If can manage a limit in this mode

public List<ExampleModel> listExampleModel() {
    return listExampleModel(null, null);
}

public List<ExampleModel> listExampleModel(Integer first, Integer count) {
    Query tmp = getSession().createQuery("from ExampleModel");

    if (first != null)
        tmp.setFirstResult(first);
    if (count != null)
        tmp.setMaxResults(count);

    return (List<ExampleModel>)tmp.list();
}

This is a really simple code to handle a limit or a list.

Here is a more strict version:

^([-+]?\d{1,2}[.]\d+),\s*([-+]?\d{1,3}[.]\d+)$

• Latitude = -90 -- +90
• Longitude = -180 -- +180

This works, but does not animate.

$('.btn-navbar').addClass('collapsed');
$('.nav-collapse').removeClass('in').css('height', '0');

I had the same question. This works great in Wordpress!

It's not necessary to rewrite everything. I recommend doing this instead:

Post this inside your .m file of your custom cell.

- (void)layoutSubviews {
    [super layoutSubviews];
    self.imageView.frame = CGRectMake(0,0,32,32);
}

This should do the trick nicely. :]

With recent version of Pandas, you can do df.N.hist(by=df.Letter)

Just like with the solutions above, the axes will be different for each subplot. I have not solved that one yet.

There is a Hidden helper alongside HiddenFor which lets you set the value.

@Html.Hidden("RequiredProperty", "default")

EDIT Based on the edit you've made to the question, you could do this, but I believe you're moving into territory where it will be cheaper and more effective, in the long run, to fight for making the code change. As has been said, even by yourself, the controller or view model should be setting the default.

This code:

<ul>
@{
        var stacks = new System.Diagnostics.StackTrace().GetFrames();
        foreach (var frame in stacks)
        {
            <li>@frame.GetMethod().Name - @frame.GetMethod().DeclaringType</li>
        }
}
</ul>

Will give output like this:

Execute - ASP._Page_Views_ViewDirectoryX__SubView_cshtml
ExecutePageHierarchy - System.Web.WebPages.WebPageBase
ExecutePageHierarchy - System.Web.Mvc.WebViewPage
ExecutePageHierarchy - System.Web.WebPages.WebPageBase
RenderView - System.Web.Mvc.RazorView
Render - System.Web.Mvc.BuildManagerCompiledView
RenderPartialInternal - System.Web.Mvc.HtmlHelper
RenderPartial - System.Web.Mvc.Html.RenderPartialExtensions
Execute - ASP._Page_Views_ViewDirectoryY__MainView_cshtml

So assuming the MVC framework will always go through the same stack, you can grab var frame = stacks[8]; and use the declaring type to determine who your parent view is, and then use that determination to set (or not) the default value. You could also walk the stack instead of directly grabbing [8] which would be safer but even less efficient.

Sometime we get this error when we select static character as a field in source query/view/procedure and the destination field data type in Unicode.

Below is the issue i faced: I used the script below at source

and got the error message Column "CATEGORY" cannot convert between Unicode and non-Unicode string data types. as below: error message

Resolution: I tried multiple options but none worked for me. Then I prefixed the static value with N to make in Unicode as below:

SELECT N'STUDENT DETAIL' CATEGORY, NAME, DATEOFBIRTH FROM STUDENTS
UNION
SELECT N'FACULTY DETAIL' CATEGORY, NAME, DATEOFBIRTH FROM FACULTY

if(A && B){ }

Try this:

CASE WHEN table3.col3 IS NULL THEN table2.col3 ELSE table3.col3 END as col4

The as col4 should go at the end of the CASE the statement. Also note that you're missing the END too.

Another probably more simple option would be:

IIf([table3.col3] Is Null,[table2.col3],[table3.col3])

Just to clarify, MS Access does not support COALESCE. If it would that would be the best way to go.

Edit after radical question change:

To turn the query into SQL Server then you can use COALESCE (so it was technically answered before too):

SELECT dbo.AdminID.CountryID, dbo.AdminID.CountryName, dbo.AdminID.RegionID, 
dbo.AdminID.[Region name], dbo.AdminID.DistrictID, dbo.AdminID.DistrictName,
dbo.AdminID.ADMIN3_ID, dbo.AdminID.ADMIN3,
COALESCE(dbo.EU_Admin3.EUID, dbo.EU_Admin2.EUID)
FROM dbo.AdminID

BTW, your CASE statement was missing a , before the field. That's why it didn't work.

If it's going into an HTML attribute, you'll need to both HTML-encode (as a minimum: > to &gt; < to &lt and " to ") it, and escape single-quotes (with a backslash) so they don't interfere with your javascript quoting.

Best way to do it is with your templating system (extending it, if necessary), but you could simply make a couple of escaping/encoding functions and wrap them both around any data that's going in there.

And yes, it's perfectly valid (correct, even) to HTML-escape the entire contents of your HTML attributes, even if they contain javascript.

I know it's an old question, but I just had to find solution for multiple rows update where multiple records had to updated with different values based on their IDs and I found that I can use a a scalar-subselect:

UPDATE PROJECT
  SET DEPTNO =
        (SELECT WORKDEPT FROM EMPLOYEE
           WHERE PROJECT.RESPEMP = EMPLOYEE.EMPNO)
  WHERE RESPEMP='000030'

(with WHERE optional, of course)

Also, I found that it is critical to specify that no NULL values would not be used in this update (in case not all records in first table have corresponding record in the second one), this way:

UPDATE PROJECT
  SET DEPTNO =
        (SELECT WORKDEPT FROM EMPLOYEE
           WHERE PROJECT.RESPEMP = EMPLOYEE.EMPNO)
  WHERE RESPEMP IN (SELECT EMPNO FROM EMPLOYEE)

The compiler isn't smart enough to know that <, >, and == are a "complete set". You can let it know that by removing the condition "if(val == sorted[mid])" -- it's redundant. Jut say "else return mid;"

you would put them inside a <p> or a <div>

There's a C implementation here:

Should be very straightforward to convert to C#, as almost no functions are called - just calculations.

found via Google

I don't know exactly what you mean by efficiency but this is straightforward and it works for me:

SELECT
    DB_NAME(db.database_id) DatabaseName,
    (CAST(mfrows.RowSize AS FLOAT)*8)/1024 RowSizeMB,
    (CAST(mflog.LogSize AS FLOAT)*8)/1024 LogSizeMB,
    (CAST(mfstream.StreamSize AS FLOAT)*8)/1024 StreamSizeMB,
    (CAST(mftext.TextIndexSize AS FLOAT)*8)/1024 TextIndexSizeMB
FROM sys.databases db
    LEFT JOIN (SELECT database_id, SUM(size) RowSize FROM sys.master_files WHERE type = 0 GROUP BY database_id, type) mfrows ON mfrows.database_id = db.database_id
    LEFT JOIN (SELECT database_id, SUM(size) LogSize FROM sys.master_files WHERE type = 1 GROUP BY database_id, type) mflog ON mflog.database_id = db.database_id
    LEFT JOIN (SELECT database_id, SUM(size) StreamSize FROM sys.master_files WHERE type = 2 GROUP BY database_id, type) mfstream ON mfstream.database_id = db.database_id
    LEFT JOIN (SELECT database_id, SUM(size) TextIndexSize FROM sys.master_files WHERE type = 4 GROUP BY database_id, type) mftext ON mftext.database_id = db.database_id

With results like:

DatabaseName  RowSizeMB LogSizeMB StreamSizeMB TextIndexSizeMB
------------- --------- --------- ------------ ---------------
master        4         1.25      NULL         NULL

tempdb        8         0.5       NULL         NULL

Note: was inspired by this article

var startTime = getTime(document.getElementById('startTime').value);
                var endTime = getTime(document.getElementById('endTime').value);


                var sts = startTime.split(":");
                var ets = endTime.split(":");

                var stMin = (parseInt(sts[0]) * 60 + parseInt(sts[1]));
                var etMin = (parseInt(ets[0]) * 60 + parseInt(ets[1]));
                if( etMin > stMin) {
                // do your stuff...
                }

Int cannot accept null but if developer are using int? then you store null in int like int i = null; // not accept int? i = null; // its working mostly use for pagination in MVC Pagelist

This would work just fine, set the height to desired pixel

#inner-right{
            height: 100px;
            overflow:auto;
            }

The temporary tables are defined in "tempdb", and the table names are "mangled".

This query should do the trick:

select c.*
from tempdb.sys.columns c
inner join tempdb.sys.tables t ON c.object_id = t.object_id
where t.name like '#MyTempTable%'

This method opens a file in the private data area of the application. You cannot open any files in subdirectories in this area or from entirely other areas using this method. So use the constructor of the FileInputStream directly to pass the path with a directory in it.

You can take both the collections in two different lists, say list1 and list2.

Then just write

list1.RemoveAll(Item => list2.Contains(Item));

This will work.

HTTPS is so powerful because it uses asymmetric cryptography. This type of cryptography not only allows you to create an encrypted tunnel but you can verify that you are talking to the right person, and not a hacker.

Here is Java source code which uses the asymmetric cipher RSA (used by PGP) to communicate: http://www.hushmail.com/services/downloads/

You can use directly a set collection to remove duplicate, then cast it back to an array

var myArray = [1, 4, 2, 2, 6, 24, 15, 2, 60, 15, 6]
var mySet = Set<Int>(myArray)

myArray = Array(mySet) // [2, 4, 60, 6, 15, 24, 1]

Then you can order your array as you want

myArray.sort{$0 < $1} // [1, 2, 4, 6, 15, 24, 60]

If you need to add two strings you have to use the '+' operator

hence

msg['Subject'] = 'your string' + sys.argv[1]

and also you have to import sys in the beginning

as

import sys

msg['Subject'] = "Auto Hella Restart Report " + sys.argv[1]

Quick Answer

Use index_col=False instead of index_col=None when you have delimiters at the end of each line to turn off index column inference and discard the last column.

More Detail

After looking at the data, there is a comma at the end of each line. And this quote (the documentation has been edited since the time this post was created):

index_col: column number, column name, or list of column numbers/names, to use as the index (row labels) of the resulting DataFrame. By default, it will number the rows without using any column, unless there is one more data column than there are headers, in which case the first column is taken as the index.

from the documentation shows that pandas believes you have n headers and n+1 data columns and is treating the first column as the index.

EDIT 10/20/2014 - More information

I found another valuable entry that is specifically about trailing limiters and how to simply ignore them:

If a file has one more column of data than the number of column names, the first column will be used as the DataFrame’s row names: ...

Ordinarily, you can achieve this behavior using the index_col option.

There are some exception cases when a file has been prepared with delimiters at the end of each data line, confusing the parser. To explicitly disable the index column inference and discard the last column, pass index_col=False: ...

@Garret Wilson Thank you so much! As a noob to android coding, I've been stuck with the preferences incompatibility issue for so many hours, and I find it so disappointing they deprecated the use of some methods/approaches for new ones that aren't supported by the older APIs thus having to resort to all sorts of workarounds to make your app work in a wide range of devices. It's really frustrating!

Your class is great, for it allows you to keep working in new APIs wih preferences the way it used to be, but it's not backward compatible. Since I'm trying to reach a wide range of devices I tinkered with it a bit to make it work in pre API 11 devices as well as in newer APIs:

import android.annotation.TargetApi;
import android.os.Bundle;
import android.preference.PreferenceActivity;
import android.preference.PreferenceFragment;

public class MyPrefsActivity extends PreferenceActivity
{
    private static int prefs=R.xml.myprefs;

    @Override
    protected void onCreate(final Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        try {
            getClass().getMethod("getFragmentManager");
            AddResourceApi11AndGreater();
        } catch (NoSuchMethodException e) { //Api < 11
            AddResourceApiLessThan11();
        }
    }

    @SuppressWarnings("deprecation")
    protected void AddResourceApiLessThan11()
    {
        addPreferencesFromResource(prefs);
    }

    @TargetApi(11)
    protected void AddResourceApi11AndGreater()
    {
        getFragmentManager().beginTransaction().replace(android.R.id.content,
                new PF()).commit();
    }

    @TargetApi(11)
    public static class PF extends PreferenceFragment
    {       
        @Override
        public void onCreate(final Bundle savedInstanceState)
        {
            super.onCreate(savedInstanceState);
            addPreferencesFromResource(MyPrefsActivity.prefs); //outer class
            // private members seem to be visible for inner class, and
            // making it static made things so much easier
        }
    }
}

Tested in two emulators (2.2 and 4.2) with success.

Why my code looks so crappy:

I'm a noob to android coding, and I'm not the greatest java fan.

In order to avoid the deprecated warning and to force Eclipse to allow me to compile I had to resort to annotations, but these seem to affect only classes or methods, so I had to move the code onto two new methods to take advantage of this.

I wouldn't like having to write my xml resource id twice anytime I copy&paste the class for a new PreferenceActivity, so I created a new variable to store this value.

I hope this will be useful to somebody else.

P.S.: Sorry for my opinionated views, but when you come new and find such handicaps, you can't help it but to get frustrated!

You can attach one and even more databases and work with it in the same way like using sqlite dbname.db

sqlite3
:
sqlite> attach "mydb.sqlite" as db1;

and u can see all attached databases with .databases

where in normal way the main is used for the command-line db

.databases
seq  name             file

I saw that the question is already answered, but if you'd like to learn more details, there are a total of 3 cases of communication between components:

• Case 1: Parent to Child communication
• Case 2: Child to Parent communication
• Case 3: Not-related components (any component to any component) communication

If you'd like to use dynamic mapping, and don't want to clutter up your model with attributes, this approach worked for me

Usage:

var settings = new JsonSerializerSettings();
settings.DateFormatString = "YYYY-MM-DD";
settings.ContractResolver = new CustomContractResolver();
this.DataContext = JsonConvert.DeserializeObject<CountResponse>(jsonString, settings);

Logic:

public class CustomContractResolver : DefaultContractResolver
{
    private Dictionary<string, string> PropertyMappings { get; set; }

    public CustomContractResolver()
    {
        this.PropertyMappings = new Dictionary<string, string> 
        {
            {"Meta", "meta"},
            {"LastUpdated", "last_updated"},
            {"Disclaimer", "disclaimer"},
            {"License", "license"},
            {"CountResults", "results"},
            {"Term", "term"},
            {"Count", "count"},
        };
    }

    protected override string ResolvePropertyName(string propertyName)
    {
        string resolvedName = null;
        var resolved = this.PropertyMappings.TryGetValue(propertyName, out resolvedName);
        return (resolved) ? resolvedName : base.ResolvePropertyName(propertyName);
    }
}

You also need add these lines in PostgreSQL and restart the server:

log_directory = 'pg_log'                    
log_filename = 'postgresql-dateformat.log'
log_statement = 'all'
logging_collector = on

The example below is based on the html5rocks solution. It uses the browser's FileReader() function. Newer browsers only.

See http://www.html5rocks.com/en/tutorials/file/dndfiles/#toc-reading-files

In this example, the user selects an HTML file. It uploaded into the <textarea>.

<form enctype="multipart/form-data">
<input id="upload" type=file   accept="text/html" name="files[]" size=30>
</form>

<textarea class="form-control" rows=35 cols=120 id="ms_word_filtered_html"></textarea>

<script>
function handleFileSelect(evt) {
    var files = evt.target.files; // FileList object

    // use the 1st file from the list
    f = files[0];

    var reader = new FileReader();

    // Closure to capture the file information.
    reader.onload = (function(theFile) {
        return function(e) {

          jQuery( '#ms_word_filtered_html' ).val( e.target.result );
        };
      })(f);

      // Read in the image file as a data URL.
      reader.readAsText(f);
  }

  document.getElementById('upload').addEventListener('change', handleFileSelect, false);
</script>

I know this does not answer your question, but I always end up on this page, when I search for the matplotlib solution to histograms, because the simple histogram_demo was removed from the matplotlib example gallery page.

Here is a solution, which doesn't require numpy to be imported. I only import numpy to generate the data x to be plotted. It relies on the function hist instead of the function bar as in the answer by @unutbu.

import numpy as np
mu, sigma = 100, 15
x = mu + sigma * np.random.randn(10000)

import matplotlib.pyplot as plt
plt.hist(x, bins=50)
plt.savefig('hist.png')

Curl: SSL certificate problem, verify that the CA cert is OK

07 April 2006

When opening a secure url with Curl you may get the following error:

SSL certificate problem, verify that the CA cert is OK

I will explain why the error and what you should do about it.

The easiest way of getting rid of the error would be adding the following two lines to your script . This solution poses a security risk tho.

//WARNING: this would prevent curl from detecting a 'man in the middle' attack
curl_setopt ($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt ($ch, CURLOPT_SSL_VERIFYPEER, 0); 

Let see what this two parameters do. Quoting the manual.

CURLOPT_SSL_VERIFYHOST: 1 to check the existence of a common name in the SSL peer certificate. 2 to check the existence of a common name and also verify that it matches the hostname provided.

CURLOPT_SSL_VERIFYPEER: FALSE to stop CURL from verifying the peer's certificate. Alternate certificates to verify against can be specified with the CURLOPT_CAINFO option or a certificate directory can be specified with the CURLOPT_CAPATH option. CURLOPT_SSL_VERIFYHOST may also need to be TRUE or FALSE if CURLOPT_SSL_VERIFYPEER is disabled (it defaults to 2). Setting CURLOPT_SSL_VERIFYHOST to 2 (This is the default value) will garantee that the certificate being presented to you have a 'common name' matching the URN you are using to access the remote resource. This is a healthy check but it doesn't guarantee your program is not being decieved.

Enter the 'man in the middle'

Your program could be misleaded into talking to another server instead. This can be achieved through several mechanisms, like dns or arp poisoning ( This is a story for another day). The intruder can also self-sign a certificate with the same 'comon name' your program is expecting. The communication would still be encrypted but you would be giving away your secrets to an impostor. This kind of attack is called 'man in the middle'

Defeating the 'man in the middle'

Well, we need to to verify the certificate being presented to us is good for real. We do this by comparing it against a certificate we reasonable* trust.

If the remote resource is protected by a certificate issued by one of the main CA's like Verisign, GeoTrust et al, you can safely compare against Mozilla's CA certificate bundle which you can get from http://curl.haxx.se/docs/caextract.html

Save the file cacert.pem somewhere in your server and set the following options in your script.

curl_setopt ($ch, CURLOPT_SSL_VERIFYPEER, TRUE); 
curl_setopt ($ch, CURLOPT_CAINFO, "pathto/cacert.pem");

Came here with a similar problem and, yes, my Sandbox was enabled. I disabled it and, voila, the login problem went away. I must warn that this problem does not affect developers and website administrators as Facebook allows those users to see the app. For this reason, I couldn't even believe that users complained about not being able to login, as I was able to login with no problems at all.

Obviously $_POST['month'] is not set. Maybe there's a mistake in your HTML form definition, or maybe something else is causing this. Whatever the cause, you should always check if a variable exists before using it, so

if(isset($_POST['month'])) {
   $month = $_POST['month'];
} else {
   //month is not set, do something about it, raise an error, throw an exception, orwahtever
}

I had a form with 11 submit buttons on it, and it would always use the first submit button when the user pressed enter. I read elsewhere that it is not a good idea (bad practice) to have more than one submit button on a form, and the best way to do this is have the button you want as default, as the only submit button on the form. The other buttons should be made into "TYPE=BUTTON" and an onClick event added that calls your own submit routine in Javascript. Something like this :-

<SCRIPT Language="JavaScript">
function validform()
{
  // do whatever you need to validate the form, and return true or false accordingly
}

function mjsubmit()
{
  if (validform()) { document.form1.submit(); return true;}
  return false;
}
</SCRIPT>
<INPUT TYPE=BUTTON NAME="button1" VALUE="button1" onClick="document.form1.submitvalue='button1'; return mjsubmit();">
<INPUT TYPE=BUTTON NAME="button2" VALUE="button2" onClick="document.form1.submitvalue='button2'; return mjsubmit();">
<INPUT TYPE=SUBMIT NAME="button3" VALUE="button3" onClick="document.form1.submitvalue='button3'; return validform();">
<INPUT TYPE=BUTTON NAME="button4" VALUE="button4" onClick="document.form1.submitvalue='button4'; return mjsubmit();">

Here, button3 is the default, and although you are programmatically submitting the form with the other buttons, the mjsubmit routine validates them. HTH.

Very quick Interface Builder solution:

For any number of views to be evenly spaced within a superview, simply give each an "Align Center X to superview" constraint for horizontal layout, or "Align Center Y superview" for vertical layout, and set the Multiplier to be N:p (NOTE: some have had better luck with p:N - see below)

where

N = total number of views, and

p = position of the view including spaces

First position is 1, then a space, making the next position 3, so p becomes a series [1,3,5,7,9,...]. Works for any number of views.

So, if you have 3 views to space out, it looks like this:

EDIT Note: The choice of N:p or p:N depends on the relation order of your alignment constraint. If "First Item" is Superview.Center, you may use p:N, while if Superview.Center is "Second Item", you may use N:p. If in doubt, just try both out... :-)

To return the client side date you can use the following javascript:

var d = new Date();
var month = d.getMonth()+1;
var date = d.getDate()+"."+month+"."+d.getFullYear();
document.getElementById('date').innerHTML = date;

or in jQuery:

var d = new Date();
var month = d.getMonth()+1;
var date = d.getDate()+"."+month+"."+d.getFullYear();
$('#date').html(date);

equivalent to following PHP:

<?php date("j.n.Y"); ?>

To get equivalent to the following PHP (i.e. leading 0's):

<?php date("d.m.Y"); ?>

JavaScript:

var d = new Date();
var day = d.getDate();
var month = d.getMonth()+1;

if(day < 10){
    day = "0"+d.getDate();
}

if(month < 10){
    month = "0"+eval(d.getMonth()+1);
}

var date = day+"."+month+"."+d.getFullYear();
document.getElementById('date').innerHTML = date;

jQuery:

var d = new Date();
var day = d.getDate();
var month = d.getMonth()+1;

if(day < 10){
    day = "0"+d.getDate();
}

if(month < 10){
    month = "0"+eval(d.getMonth()+1);
}

var date = day+"."+month+"."+d.getFullYear();
$('#date').html(date);

Ok guys I found the reason for my encoding issue.

The fault was in my build process. I didn't tell Maven in my pom.xml file to build the project with the UTF-8 encoding. Therefor Maven just took the default encoding from my system which is MacRoman and build it with the MacRoman encoding.

Luckily Maven is warning you about this when building your project (BUT there is a good chance that the warning disappears to fast from your screen because of all the other messages).

Here is the property you need to set in the pom.xml file:

<properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    ...
</properties>

Thank you guys for all your help. Without you guys I wouldn't be able to figure this out!

One quick and easy way:

function paintSvgToCanvas(uSvg, uCanvas) {

    var pbx = document.createElement('img');

    pbx.style.width  = uSvg.style.width;
    pbx.style.height = uSvg.style.height;

    pbx.src = 'data:image/svg+xml;base64,' + window.btoa(uSvg.outerHTML);
    uCanvas.getContext('2d').drawImage(pbx, 0, 0);

}

This worked best for me:

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:top="-5dp" android:left="-5dp" android:right="-5dp" android:bottom="0dp">
        <shape android:shape="rectangle">
            <stroke android:width="4dp" android:color="#ff0000"/>
        </shape>
    </item>
</layer-list>

Shows the line on the bottom only. You can easily change with stroke width to size you like and also update the top, left, right on the accordingly.

MySQL, SQL Server, PostgreSQL, SQLite support using the percent sign as the modulus:

WHERE column % 2 = 1

For Oracle, you have to use the MOD function:

WHERE MOD(column, 2) = 1

if by .add you mean .append, then the result is the same if #myDiv is empty.

is the performance the same? dont know.

.html(x) ends up doing the same thing as .empty().append(x)

In a nutshell, I think that the selection sort searches for the smallest value in the array first, and then does the swap whereas the insertion sort takes a value and compares it to each value left to it (behind it). If the value is smaller, it swaps. Then, the same value is compared again and if it is smaller to the one behind it, it swaps again. I hope that makes sense!

In addition to the previous comments browser support for word-wrap seems to be a bit better than for word-break.

You get SyntaxError error exception because Python has no && operator. It has and and & where the latter one is the correct choice to create boolean expressions on Column (| for a logical disjunction and ~ for logical negation).

Condition you created is also invalid because it doesn't consider operator precedence. & in Python has a higher precedence than == so expression has to be parenthesized.

(col("Age") == "") & (col("Survived") == "0")
## Column<b'((Age = ) AND (Survived = 0))'>

On a side note when function is equivalent to case expression not WHEN clause. Still the same rules apply. Conjunction:

df.where((col("foo") > 0) & (col("bar") < 0))

Disjunction:

df.where((col("foo") > 0) | (col("bar") < 0))

You can of course define conditions separately to avoid brackets:

cond1 = col("Age") == "" 
cond2 = col("Survived") == "0"

cond1 & cond2

I guess something like this would work:

Add System.ServiceProcess to your project references (It's on the .NET tab).

using System.ServiceProcess;

ServiceController sc = new ServiceController(SERVICENAME);

switch (sc.Status)
{
    case ServiceControllerStatus.Running:
        return "Running";
    case ServiceControllerStatus.Stopped:
        return "Stopped";
    case ServiceControllerStatus.Paused:
        return "Paused";
    case ServiceControllerStatus.StopPending:
        return "Stopping";
    case ServiceControllerStatus.StartPending:
        return "Starting";
    default:
        return "Status Changing";
}

Edit: There is also a method sc.WaitforStatus() that takes a desired status and a timeout, never used it but it may suit your needs.

Edit: Once you get the status, to get the status again you will need to call sc.Refresh() first.

Reference: ServiceController object in .NET.

You have compiled your code with references to the correct math.h header file, but when you attempted to link it, you forgot the option to include the math library. As a result, you can compile your .o object files, but not build your executable.

As Paul has already mentioned add "-lm" to link with the math library in the step where you are attempting to generate your executable.

In the comment, linuxD asks:

Why for sin() in <math.h>, do we need -lm option explicitly; but, not for printf() in <stdio.h>?

Because both these functions are implemented as part of the "Single UNIX Specification". This history of this standard is interesting, and is known by many names (IEEE Std 1003.1, X/Open Portability Guide, POSIX, Spec 1170).

This standard, specifically separates out the "Standard C library" routines from the "Standard C Mathematical Library" routines (page 277). The pertinent passage is copied below:

Standard C Library

The Standard C library is automatically searched by cc to resolve external references. This library supports all of the interfaces of the Base System, as defined in Volume 1, except for the Math Routines.

Standard C Mathematical Library

This library supports the Base System math routines, as defined in Volume 1. The cc option -lm is used to search this library.

The reasoning behind this separation was influenced by a number of factors:

1. The UNIX wars led to increasing divergence from the original AT&T UNIX offering.
2. The number of UNIX platforms added difficulty in developing software for the operating system.
3. An attempt to define the lowest common denominator for software developers was launched, called 1988 POSIX.
4. Software developers programmed against the POSIX standard to provide their software on "POSIX compliant systems" in order to reach more platforms.
5. UNIX customers demanded "POSIX compliant" UNIX systems to run the software.

The pressures that fed into the decision to put -lm in a different library probably included, but are not limited to:

1. It seems like a good way to keep the size of libc down, as many applications don't use functions embedded in the math library.
2. It provides flexibility in math library implementation, where some math libraries rely on larger embedded lookup tables while others may rely on smaller lookup tables (computing solutions).
3. For truly size constrained applications, it permits reimplementations of the math library in a non-standard way (like pulling out just sin() and putting it in a custom built library.

In any case, it is now part of the standard to not be automatically included as part of the C language, and that's why you must add -lm.

There is no such particular way in which you can initialize the array after declaring it once.

There are three options only:

1.) initialize them in different lines :

int array[SIZE];

array[0] = 1;
array[1] = 2;
array[2] = 3;
array[3] = 4;
//...
//...
//...

But thats not what you want i guess.

2.) Initialize them using a for or while loop:

for (i = 0; i < MAX ; i++)  {
    array[i] = i;
}

This is the BEST WAY by the way to achieve your goal.

3.) In case your requirement is to initialize the array in one line itself, you have to define at-least an array with initialization. And then copy it to your destination array, but I think that there is no benefit of doing so, in that case you should define and initialize your array in one line itself.

And can I ask you why specifically you want to do so???

CSS 3 introduces rgba colour, and you can combine it with graphics for a backwards compatible solution.

Okay, here are the explanations.

e.keyCode - used to get the number that represents the key on the keyboard

e.charCode - a number that represents the unicode character of the key on keyboard

e.which - (jQuery specific) is a property introduced in jQuery (DO Not use in plain javascript)

Below is the code snippet to get the keyCode and charCode

<script>
// get key code
function getKey(event) {
  event = event || window.event;
  var keyCode = event.which || event.keyCode;
  alert(keyCode);
}

// get char code
function getChar(event) {
  event = event || window.event;
  var keyCode = event.which || event.keyCode;
  var typedChar = String.fromCharCode(keyCode);
  alert(typedChar);
}
</script>

The one below works for me every time..

This site also has a few other suggestions, but this no-nonsense, no-worry one is available in a github:gist and answers your question (pasted here for convenience):

function hideAddressBar()
{
  if(!window.location.hash)
  {
      if(document.height < window.outerHeight)
      {
          document.body.style.height = (window.outerHeight + 50) + 'px';
      }

      setTimeout( function(){ window.scrollTo(0, 1); }, 50 );
  }
}

window.addEventListener("load", function(){ if(!window.pageYOffset){ hideAddressBar(); } } );
window.addEventListener("orientationchange", hideAddressBar );

As far as I can tell, the combination of extra height added to the page (which caused problems for you) and the scrollTo() statement make the address bar disappear.

From the same site the 'simplest' solution to hiding the address bar is using the scrollTo() method:

window.addEventListener("load", function() { window.scrollTo(0, 1); });

This will hide the address bar until the user scrolls.

This site places the same method inside a timeout function (the justification is not explained, but it claims the code doesn't work well without it):

// When ready...
window.addEventListener("load",function() {
  // Set a timeout...
  setTimeout(function(){
    // Hide the address bar!
     window.scrollTo(0, 1);
  }, 0);
});

I got an error when I used

<git config --global http.proxy http://user:password@proxy_addr:port>

The error is that the config file cannot be identified as there is no such file. I changed the command to

<git config --system http.proxy http://user:password@proxy_addr:port>

I am running git on the Windows 7 command prompt.
The above command references the config file in GIT_HOME/etc/gitconfig.
The --global option does not.

Your compound PRIMARY KEY specification already does what you want. Omit the line that's giving you a syntax error, and omit the redundant CONSTRAINT (already implied), too:

               tag3 VARCHAR(20),
               PRIMARY KEY(question_id, tag_id)
      );

     tag3        | character varying(20) |
    Indexes:

Shortest, most safe and easiest solution is:

long myValue=...;
int asInt = Long.valueOf(myValue).intValue();

Do note, the behavior of Long.valueOf is as such:

Using this code:

System.out.println("Long max: " + Long.MAX_VALUE);
System.out.println("Int max: " + Integer.MAX_VALUE);        
long maxIntValue = Integer.MAX_VALUE;
System.out.println("Long maxIntValue to int: " + Long.valueOf(maxIntValue).intValue());
long maxIntValuePlusOne = Integer.MAX_VALUE + 1;
System.out.println("Long maxIntValuePlusOne to int: " + Long.valueOf(maxIntValuePlusOne).intValue());
System.out.println("Long max to int: " + Long.valueOf(Long.MAX_VALUE).intValue());

Results into:

Long max: 9223372036854775807
Int max: 2147483647
Long max to int: -1
Long maxIntValue to int: 2147483647
Long maxIntValuePlusOne to int: -2147483648

you can also add inline css for adding image as a background as per below example

<div class="item active" style="background-image: url(../../foo.png);">

One of the good things about handle.exe is that you can run it as a subprocess and parse the output.

We do this in our deployment script - works like a charm.

Used this page a few times to copy and paste quick commands into composer, so I wrote a command that does these commands in one single artisan command.

namespace App\Console\Commands\Admin;

use Illuminate\Console\Command;

class ClearEverything extends Command
{

    protected $signature = 'traqza:clear-everything';

    protected $description = 'Clears routes, config, cache, views, compiled, and caches config.';

    public function __construct()
    {
        parent::__construct();
    }

    public function handle()
    {
        $validCommands = array('route:clear', 'config:clear', 'cache:clear', 'view:clear', 'clear-compiled', 'config:cache');
        foreach ($validCommands as $cmd) {
            $this->call('' . $cmd . '');

        }
    }
}

Place in app\Console\Commands\Admin folder

then run command in composer php artisan traqza:clear-everything

Happy coding.

The error message clearly states what the problem is. You need the intl extension installed.

Step 1: install PHP intl you comfortable version

$sudo apt-get install php-intl

step 2:

For XAMPP Server intl extension is already installed, you need to enable this extension to uncomment below the line in your php.ini file. Php.ini file is located at c:\xampp\php\php.ini or where you have installed XAMPP.

Before uncomment:

;extension=php_intl.dll ;extension=php_mbstring.dll

After uncommenting:

extension=php_intl.dll extension=php_mbstring.dll

Since Windows 10 15063 upwards

Since Windows 10 build 15063, there is a new feature called "Implicit Visibility conversion" that binds Visibility to bool value natively - There is no need anymore to use a converter.

(see https://social.technet.microsoft.com/wiki/contents/articles/34846.uwp-compiled-binding-windows-10-anniversary-update.aspx#Implicit_Visibility_conversion).

My code (which supposes that MVVM is used, and Template 10 as well):

<!-- In XAML -->
<StackPanel x:Name="Msg_StackPanel" Visibility="{x:Bind ViewModel.ShowInlineHelp}" Orientation="Horizontal" Margin="0,24,0,0">
    <TextBlock Text="Frosty the snowman was a jolly happy soul" Margin="0,0,8,0"/>
    <SymbolIcon Symbol="OutlineStar "/>
    <TextBlock Text="With a corncob pipe and a button nose" Margin="8,0,0,0"/>
</StackPanel>

<!-- in companion View-Model -->
public bool ShowInlineHelp // using T10 SettingsService
{ 
    get { return (_settings.ShowInlineHelp); }
    set { _settings.ShowInlineHelp = !value; base.RaisePropertyChanged(); }
}

From ScottGu's blog:

Starting with the ASP.NET MVC 3 Beta release, you can now add a file called _ViewStart.cshtml (or _ViewStart.vbhtml for VB) underneath the \Views folder of your project:

The _ViewStart file can be used to define common view code that you want to execute at the start of each View’s rendering. For example, we could write code within our _ViewStart.cshtml file to programmatically set the Layout property for each View to be the SiteLayout.cshtml file by default:

Because this code executes at the start of each View, we no longer need to explicitly set the Layout in any of our individual view files (except if we wanted to override the default value above).

Important: Because the _ViewStart.cshtml allows us to write code, we can optionally make our Layout selection logic richer than just a basic property set. For example: we could vary the Layout template that we use depending on what type of device is accessing the site – and have a phone or tablet optimized layout for those devices, and a desktop optimized layout for PCs/Laptops. Or if we were building a CMS system or common shared app that is used across multiple customers we could select different layouts to use depending on the customer (or their role) when accessing the site.

This enables a lot of UI flexibility. It also allows you to more easily write view logic once, and avoid repeating it in multiple places.

Also see this.

In a more general sense this ability of MVC framework to "know" about _Viewstart.cshtml is called "Coding by convention".

Convention over configuration (also known as coding by convention) is a software design paradigm which seeks to decrease the number of decisions that developers need to make, gaining simplicity, but not necessarily losing flexibility. The phrase essentially means a developer only needs to specify unconventional aspects of the application. For example, if there's a class Sale in the model, the corresponding table in the database is called “sales” by default. It is only if one deviates from this convention, such as calling the table “products_sold”, that one needs to write code regarding these names.

Wikipedia

There's no magic to it. Its just been written into the core codebase of the MVC framework and is therefore something that MVC "knows" about. That why you don't find it in the .config files or elsewhere; it's actually in the MVC code. You can however override to alter or null out these conventions.

I know this is old but I think this will help anyone else who comes looking...

                m = hashlib.md5()
                word = word.rstrip('\n')            
                m.update(word.encode('utf-8'))
                word_hash = m.hexdigest()
                if word_hash==hash:
                    print('The word, hash combination is ' + word + ',' + hash)
                    count += 1
                    break
                i += 1
        print('Itiration is ' + str(i))
    if count == 0:
        print('The hash given does not correspond to any supplied word in the wordlist.')
    else:
        print('Total passwords identified is: ' + str(count))
sys.exit()

An alternative is to use String.format:

double[] arr = { 23.59004,
    35.7,
    3.0,
    9
};

for ( double dub : arr ) {
  System.out.println( String.format( "%.2f", dub ) );
}

output:

23.59
35.70
3.00
9.00

You could also use System.out.format (same method signature), or create a java.util.Formatter which works in the same way.

You can use Object.assign() to merge them into a new object:

const response = {_x000D_
  lat: -51.3303,_x000D_
  lng: 0.39440_x000D_
}_x000D_
_x000D_
const item = {_x000D_
  id: 'qwenhee-9763ae-lenfya',_x000D_
  address: '14-22 Elder St, London, E1 6BT, UK'_x000D_
}_x000D_
_x000D_
const newItem = Object.assign({}, item, { location: response });_x000D_
_x000D_
console.log(newItem );

You can also use object spread, which is a Stage 4 proposal for ECMAScript:

const response = {_x000D_
  lat: -51.3303,_x000D_
  lng: 0.39440_x000D_
}_x000D_
_x000D_
const item = {_x000D_
  id: 'qwenhee-9763ae-lenfya',_x000D_
  address: '14-22 Elder St, London, E1 6BT, UK'_x000D_
}_x000D_
_x000D_
const newItem = { ...item, location: response }; // or { ...response } if you want to clone response as well_x000D_
_x000D_
console.log(newItem );

./ is the the folder that the working file is in:

So in /index.htm ./ is the root directory
but in /css/style.css ./ is the css folder.

This is important to remember because if you move CSS from /index.htm to /css/style.css the path will change.

This can be done by adding a reference to System.IO.Compression and System.IO.Compression.Filesystem.

A sample createZipFile() method may look as following:

public static void createZipFile(string inputfile, string outputfile, CompressionLevel compressionlevel)
        {
            try
            {
                using (ZipArchive za = ZipFile.Open(outputfile, ZipArchiveMode.Update))
                {
                    //using the same file name as entry name
                    za.CreateEntryFromFile(inputfile, inputfile);
                }
            }
            catch (ArgumentException)
            {
                Console.WriteLine("Invalid input/output file.");
                Environment.Exit(-1);
            }
}

where

• inputfile= string with the file name to be compressed (for this example, you have to add the extension)
• outputfile= string with the destination zip file name

In newer version of git (2.23+) you can use:

git switch -C master origin/master

-C is same as --force-create. Related Reference Docs

function reverseString(string) {
    var reversedString = "";
    var stringLength = string.length - 1;
    for (var i = stringLength; i >= 0; i--) {
        reversedString += string[i];
    }
    return reversedString;
}

Try

df.loc[df.my_channel > 20000, 'my_channel'] = 0

Note: Since v0.20.0, ix has been deprecated in favour of loc / iloc.

No, not knowing which variables are defined is a bug, not a feature in Python.

Use dicts instead:

d = {}
d.setdefault('key', 1)
d['key'] == 1

d['key'] = 2
d.setdefault('key', 1)
d['key'] == 2

It should be mentioned that since it is entirely possible to run DLL's just as any other executable, it has long been considered a security issue. As such, there have been a number of security improvements and registry hacks (sorry no longer have ref-links) that prevents running DLL's from regular user space without extra privileges.

As a good example. I recall making these hacks, but since I no longer remember what exactly I did. I can no longer run any DLLs from normal user shell environment, even though starting various Win apps from GUI works just fine.

That said, one should definitely read "Dynamic-Link Library Security" and "Best Practices to Prevent DLL Hijacking".

First thing Correctly specify all settings in the .ENV file for Mail.

I LOST 6 HOURS FOR THIS

I achieved the goal where I have multiple images to insert in the DB as

INSERT INTO [dbo].[User]

           ,[GroupName])
           VALUES
           ('Umar'
           , (SELECT BulkColumn 
            FROM Openrowset( Bulk 'path-to-file.jpg', Single_Blob) as Image1)
           ,26
           ,(SELECT BulkColumn

            ,'Group123'
           ,'GroupABC')

You just need to check whether the file is there, by typing

cat /etc/apache2/mods-available/rewrite.load

The result line may not be commented starting with #

Use case/esac to test:

case "$var" in
  "") echo "zero length";;
esac

Replace below line with new updated working code:

@Html.DropDownList("NewsCategoriesID", (SelectList)ViewBag.NewsCategoriesID)

Now Implement new updated working code:

@Html.DropDownListFor(model => model.NewsCategoriesID, ViewBag.NewsCategoriesID as List<SelectListItem>, new {name = "NewsCategoriesID", id = "NewsCategoriesID" })

You could put the text into a div (or other container) with a width of 50%.

To get the address of p do:

int **pp = &p;

and you can go on:

int ***ppp = &pp;
int ****pppp = &ppp;
...

or, only in C++11, you can do:

auto pp = std::addressof(p);

To print the address in C, most compilers support %p, so you can simply do:

printf("addr: %p", pp);

otherwise you need to cast it (assuming a 32 bit platform)

printf("addr: 0x%u", (unsigned)pp);

In C++ you can do:

cout << "addr: " << pp;

wrap button inside <div class="text-xs-center">

<div class="text-xs-center">
  <v-btn primary>
    Signup
  </v-btn>
</div>

Dev uses it in his examples.

For centering buttons in v-card-actions we can add class="justify-center" (note in v2 class is text-center (so without xs):

<v-card-actions class="justify-center">
  <v-btn>
    Signup
  </v-btn>
</v-card-actions>

@MykolaGolubyev has already given wonderful explanation. I was looking for a solution to do somthing like this MyClass obj ( MyAnotherClass() ) but the compiler was interpreting it as a function declaration.

C++11 has braced-init-list. Using this we can do something like this

Temp t{String()};

However, this:

Temp t(String());

throws compilation error as it considers t as of type Temp(String (*)()).

#include <iostream>

class String {
public:
    String(const char* str): ptr(str)
    {
        std::cout << "Constructor: " << str << std::endl;
    }
    String(void): ptr(nullptr)
    {
        std::cout << "Constructor" << std::endl;
    }
    virtual ~String(void)
    {
        std::cout << "Destructor" << std::endl;
    }

private:
    const char *ptr;
};

class Temp {
public:
    Temp(String in): str(in)
    {
        std::cout << "Temp Constructor" << std::endl;
    }

    Temp(): str(String("hello"))
    {
        std::cout << "Temp Constructor: 2" << std::endl;
    }
    virtual ~Temp(void)
    {
        std::cout << "Temp Destructor" << std::endl;
    }

    virtual String get_str()
    {
        return str;
    }

private:
    String str;
};

int main(void)
{
    Temp t{String()}; // Compiles Success!
    // Temp t(String()); // Doesn't compile. Considers "t" as of type: Temp(String (*)())
    t.get_str(); // dummy statement just to check if we are able to access the member
    return 0;
}

I've found my optimal blocksize to be 8 MB (equal to disk cache?) I needed to wipe (some say: wash) the empty space on a disk before creating a compressed image of it. I used:

cd /media/DiskToWash/
dd if=/dev/zero of=zero bs=8M; rm zero

I experimented with values from 4K to 100M.

After letting dd to run for a while I killed it (Ctlr+C) and read the output:

36+0 records in
36+0 records out
301989888 bytes (302 MB) copied, 15.8341 s, 19.1 MB/s

As dd displays the input/output rate (19.1MB/s in this case) it's easy to see if the value you've picked is performing better than the previous one or worse.

My scores:

bs=   I/O rate
---------------
4K    13.5 MB/s
64K   18.3 MB/s
8M    19.1 MB/s <--- winner!
10M   19.0 MB/s
20M   18.6 MB/s
100M  18.6 MB/s   

Note: To check what your disk cache/buffer size is, you can use sudo hdparm -i /dev/sda

I found 3 occasions where I needed to do this:

• allocating/deallocating objects in memory created by memory-mapped-io or shared memory
• when implementing a given C interface using C++ (yes this still happens today unfortunately (because I don't have enough clout to change it))
• when implementing allocator classes

There is an open source common resource grep tool crgrep which searches within PDF files but also other resources like content nested in archives, database tables, image meta-data, POM file dependencies and web resources - and combinations of these including recursive search.

The full description under the Files tab pretty much covers what the tool supports.

I developed crgrep as an opensource tool.

Here's a small library I created you can use to make a viewport that Just Works(TM)

https://github.com/adamjgrant/a-viewport-that-works

Read this for detail :

// 1 define a function pointer and initialize to NULL

int (TMyClass::*pt2ConstMember)(float, char, char) const = NULL;

// C++

class TMyClass
{
public:
   int DoIt(float a, char b, char c){ cout << "TMyClass::DoIt"<< endl; return a+b+c;};
   int DoMore(float a, char b, char c) const
         { cout << "TMyClass::DoMore" << endl; return a-b+c; };

   /* more of TMyClass */
};
pt2ConstMember = &TMyClass::DoIt; // note: <pt2Member> may also legally point to &DoMore

// Calling Function using Function Pointer

(*this.*pt2ConstMember)(12, 'a', 'b');

Please use if condition with while loop and try.

eg.

if ($result = $conn->query($query)) {

    /* fetch associative array */
    while ($row = $result->fetch_assoc()) {

    }
    /* free result set */
    $result->free();
}

SQL does not do that. The order of the tuples in the table are not ordered by insertion date. A lot of people include a column that stores that date of insertion in order to get around this issue.

I think this need to be run from the Management Shell rather than the console, it sounds like the module isn't being imported into the Powershell console. You can add the module by running:

Add-PSSnapin Microsoft.Sharepoint.Powershell

in the Powershell console.

The best way to visualize this is to use a packet analyzer like Wireshark and follow the TCP stream. HTTP simply uses TCP to send a stream of data starting with a few lines of HTTP headers. Often this data is easy to read because it consists of HTML, CSS, or XML, but it can be any type of data that gets transfered over the internet (Executables, Images, Video, etc).

For a GET request, your computer requests a specific URL and the web server usually responds with a 200 status code and the the content of the webpage is sent directly after the HTTP response headers. This content is the same content you would see if you viewed the source of the webpage in your browser. The query string you mentioned is just part of the URL and gets included in the HTTP GET request header that your computer sends to the web server. Below is an example of an HTTP GET request to http://accel91.citrix.com:8000/OA_HTML/OALogout.jsp?menu=Y, followed by a 302 redirect response from the server. Some of the HTTP Headers are wrapped due to the size of the viewing window (these really only take one line each), and the 302 redirect includes a simple HTML webpage with a link to the redirected webpage (Most browsers will automatically redirect any 302 response to the URL listed in the Location header instead of displaying the HTML response):

For a POST request, you may still have a query string, but this is uncommon and does not have anything to do with the data that you are POSTing. Instead, the data is included directly after the HTTP headers that your browser sends to the server, similar to the 200 response that the web server uses to respond to a GET request. In the case of POSTing a simple web form this data is encoded using the same URL encoding that a query string uses, but if you are using a SOAP web service it could also be encoded using a multi-part MIME format and XML data.

For example here is what an HTTP POST to an XML based SOAP web service located at http://192.168.24.23:8090/msh looks like in Wireshark Follow TCP Stream:

For multiple checkbox with same name... Code to remove unnecessary false :

List<string> d_taxe1 = new List<string>(Request.Form.GetValues("taxe1"));
d_taxe1 = form_checkbox.RemoveExtraFalseFromCheckbox(d_taxe1);

Function

public class form_checkbox
{

    public static List<string> RemoveExtraFalseFromCheckbox(List<string> val)
    {
        List<string> d_taxe1_list = new List<string>(val);

        int y = 0;

        foreach (string cbox in val)
        {

            if (val[y] == "false")
            {
                if (y > 0)
                {
                    if (val[y - 1] == "true")
                    {
                        d_taxe1_list[y] = "remove";
                    }
                }

            }

            y++;
        }

        val = new List<string>(d_taxe1_list);

        foreach (var del in d_taxe1_list)
            if (del == "remove") val.Remove(del);

        return val;

    }      



}

Use it :

int x = 0;
foreach (var detail in d_prix){
factured.taxe1 = (d_taxe1[x] == "true") ? true : false;
x++;
}

You could try:

print ''.join(ch for ch in some_string if ch.isalnum())

There is nothing wrong with syntax of

$('#part' + number).html(text);

jQuery accepts a String (usually a CSS Selector) or a DOM Node as parameter to create a jQuery Object.

In your case you should pass a String to $() that is

$(<a string>)

Make sure you have access to the variables number and text.

To test do:

function(){
    alert(number + ":" + text);//or use console.log(number + ":" + text)
    $('#part' + number).html(text);
}); 

If you see you dont have access, pass them as parameters to the function, you have to include the uual parameters for $.get and pass the custom parameters after them.

For future reference, you can get help for any command by using the /? switch, which should explain what switches do what.

According to the set /? screen, the format for set /p is SET /P variable=[promptString] which would indicate that the p in /p is "prompt." It just prints in your example because <nul passes in a nul character which immediately ends the prompt so it just acts like it's printing. It's still technically prompting for input, it's just immediately receiving it.

/L in for /L generates a List of numbers.

From ping /?:

Usage: ping [-t] [-a] [-n count] [-l size] [-f] [-i TTL] [-v TOS]
            [-r count] [-s count] [[-j host-list] | [-k host-list]]
            [-w timeout] [-R] [-S srcaddr] [-4] [-6] target_name

Options:
    -t             Ping the specified host until stopped.
                   To see statistics and continue - type Control-Break;
                   To stop - type Control-C.
    -a             Resolve addresses to hostnames.
    -n count       Number of echo requests to send.
    -l size        Send buffer size.
    -f             Set Don't Fragment flag in packet (IPv4-only).
    -i TTL         Time To Live.
    -v TOS         Type Of Service (IPv4-only. This setting has been deprecated
                   and has no effect on the type of service field in the IP Header).
    -r count       Record route for count hops (IPv4-only).
    -s count       Timestamp for count hops (IPv4-only).
    -j host-list   Loose source route along host-list (IPv4-only).
    -k host-list   Strict source route along host-list (IPv4-only).
    -w timeout     Timeout in milliseconds to wait for each reply.
    -R             Use routing header to test reverse route also (IPv6-only).
    -S srcaddr     Source address to use.
    -4             Force using IPv4.
    -6             Force using IPv6.

It must work.

But as Günter Zöchbauer said there must be some other problem in template. I have created kinda Relevant-Plunkr-Answer. Pleas do check browser's console.

boot.ts

@Component({
selector: 'my-app'
, template: `<div> <h1> BodyContent </h1></div>

      <filter></filter>

      <button (click)="onClickSidebar()">Click Me</button>
  `
, directives: [FilterTiles] 
})


export class BodyContent {
    @ViewChild(FilterTiles) ft:FilterTiles;

    public onClickSidebar() {
        console.log(this.ft);

        this.ft.tiles.push("entered");
    } 
}

filterTiles.ts

@Component({
     selector: 'filter',
    template: '<div> <h4>Filter tiles </h4></div>'
 })


 export class FilterTiles {
     public tiles = [];

     public constructor(){};
 }

It works like a charm. Please double check your tags and references.

Thanks...

what is the exec function and its family.

The exec function family is all functions used to execute a file, such as execl, execlp, execle, execv, and execvp.They are all frontends for execve and provide different methods of calling it.

why is this function used

Exec functions are used when you want to execute (launch) a file (program).

and how does it work.

They work by overwriting the current process image with the one that you launched. They replace (by ending) the currently running process (the one that called the exec command) with the new process that has launched.

For more details: see this link.

Paste this on your command line:

export LC_CTYPE="en_US.UTF-8" 

This is not exactly a solution, but for opening new files this works great:

AdvancedNewFile

https://github.com/skuroda/Sublime-AdvancedNewFile

Command + Option + n to save a file in a new or existing directory.

So this would place your_file.html.erb in the existing views directory in a Rails app. If you needed a new directory -you would just type that as the path and then hit enter.

You can also Tab like in terminal to autocomplete for existing directories.

This does not give the sidebar navigation I am looking for, but at least helps with one significant need that is repeated often.

If you are looking to reduce the size using coding itself, you can follow this code in php.

<?php 
function compress($source, $destination, $quality) {

    $info = getimagesize($source);

    if ($info['mime'] == 'image/jpeg') 
        $image = imagecreatefromjpeg($source);

    elseif ($info['mime'] == 'image/gif') 
        $image = imagecreatefromgif($source);

    elseif ($info['mime'] == 'image/png') 
        $image = imagecreatefrompng($source);

    imagejpeg($image, $destination, $quality);

    return $destination;
}

$source_img = 'source.jpg';
$destination_img = 'destination .jpg';

$d = compress($source_img, $destination_img, 90);
?>

$d = compress($source_img, $destination_img, 90);

This is just a php function that passes the source image ( i.e., $source_img ), destination image ( $destination_img ) and quality for the image that will take to compress ( i.e., 90 ).

$info = getimagesize($source);

The getimagesize() function is used to find the size of any given image file and return the dimensions along with the file type.

The git rev-parse solution proposed by @Andy works fine if the date you're interested is the commit's date. If however you want to checkout based on the author's date, rev-parse won't work, because it doesn't offer an option to use that date for selecting the commits. Instead, you can use the following.

git checkout $(
  git log --reverse --author-date-order --pretty=format:'%ai %H' master |
  awk '{hash = $4} $1 >= "2016-04-12" {print hash; exit 0 }
)

(If you also want to specify the time use $1 >= "2016-04-12" && $2 >= "11:37" in the awk predicate.)

Straight from the ECMA-262, Fifth Edition ECMAScript Specification:

7.9.1 Rules of Automatic Semicolon Insertion

There are three basic rules of semicolon insertion:

1. When, as the program is parsed from left to right, a token (called the offending token) is encountered that is not allowed by any production of the grammar, then a semicolon is automatically inserted before the offending token if one or more of the following conditions is true:
   • The offending token is separated from the previous token by at least one LineTerminator.
   • The offending token is }.
2. When, as the program is parsed from left to right, the end of the input stream of tokens is encountered and the parser is unable to parse the input token stream as a single complete ECMAScript Program, then a semicolon is automatically inserted at the end of the input stream.
3. When, as the program is parsed from left to right, a token is encountered that is allowed by some production of the grammar, but the production is a restricted production and the token would be the first token for a terminal or nonterminal immediately following the annotation "_{[no LineTerminator here]}" within the restricted production (and therefore such a token is called a restricted token), and the restricted token is separated from the previous token by at least one LineTerminator, then a semicolon is automatically inserted before the restricted token.

However, there is an additional overriding condition on the preceding rules: a semicolon is never inserted automatically if the semicolon would then be parsed as an empty statement or if that semicolon would become one of the two semicolons in the header of a for statement (see 12.6.3).

If there is no ORDER BY clause, then TOP 100 PERCENT is redundant. (As you mention, this was the 'trick' with views)

[Hopefully the optimizer will optimize this away.]

I took a slightly different approach. Using the Card Deck wrapper

I added a style rule that limits the height of the card block:

.card .card-block {max-height:300px;overflow:auto;}

This give the following result:

>>> from sklearn import preprocessing, metrics, cross_validation

Traceback (most recent call last):

So, simply try to restart the shell!

(tested with a CSV file with 5400 rows and 26 elements by row)

   public static string[] CSVRowToStringArray(string r, char fieldSep = ',', char stringSep = '\"')  {
            bool bolQuote = false;
            StringBuilder bld = new StringBuilder();
            List<string> retAry = new List<string>();

            foreach (char c in r.ToCharArray())
                if ((c == fieldSep && !bolQuote))
                {
                    retAry.Add(bld.ToString());
                    bld.Clear();
                }
                else
                    if (c == stringSep)
                        bolQuote = !bolQuote;
                    else
                        bld.Append(c);

            /* to solve the last element problem */
            retAry.Add(bld.ToString()); /* added this line */
            return retAry.ToArray();
        }

This is done with

ANALYZE TABLE table_name;

Read more about it here.

ANALYZE TABLE analyzes and stores the key distribution for a table. During the analysis, the table is locked with a read lock for MyISAM, BDB, and InnoDB. This statement works with MyISAM, BDB, InnoDB, and NDB tables.

SnowsPenultimateNormalityTest certainly has its virtues, but you may also want to look at qqnorm.

X <- rlnorm(100)
qqnorm(X)
qqnorm(rnorm(100))

>>> average =  [1,3,2,1,1,0,24,23,7,2,727,2,7,68,7,83,2]
>>> matches = [i for i in range(0,len(average)) if average[i]<2 or average[i]>4]
>>> matches
[0, 3, 4, 5, 6, 7, 8, 10, 12, 13, 14, 15]

I think Object.keys is the best solution to this problem. For anyone that comes across this answer and is trying to find out why Object.keys is giving them ['0', '1'] instead of ['key1', 'key2'], a cautionary tale - beware the difference between "of" and "in":

I was already using Object.keys, something similar to this:

interface demo {
    key: string;
    value: string;
}

createDemo(mydemo: any): Array<demo> {
    const tempdemo: Array<demo> = [];

    // Caution: use "of" and not "in"
    for (const key of Object.keys(mydemo)) {
        tempdemo.push(
            { key: key, value: mydemo[key]}
        );
    }

    return tempdemo;
}

However, instead of

for (const key OF Object.keys(mydemo)) {

I had inadvertently wrote

for (const key IN Object.keys(mydemo)) {

which "worked" perfectly fine without any error and returned

[{key: '0', value: undefined}, {key: '1', value: undefined}]

That cost me about 2 hours googling and cursing..

(slaps forehead)

Here's a dplyr option:

library(dplyr)

# across all columns:
df %>% filter_all(any_vars(. %in% c('M017', 'M018')))

# or in only select columns:
df %>% filter_at(vars(col1, col2), any_vars(. %in% c('M017', 'M018')))                                                                                                     

I would not expect that to work

try instead

window.frames["printf"].focus();
window.frames["printf"].print();

and use

<iframe id="printf" name="printf"></iframe>

Alternatively try good old

var newWin = window.frames["printf"];
newWin.document.write('<body onload="window.print()">dddd</body>');
newWin.document.close();

if jQuery cannot hack it

Make sure that your mongo is running. I fixed this problem by trying to repair the mongodb, there I found that the directory required for the db to run was not created. It shows this error

Type: mongod, it will show the error

exception in initAndListen: 29 Data directory /data/db not found., terminating

Error happen because dbpath /data/db/ (default config) does not exist. You need to create data folder and set permission for it.

Then I create a folder on my system by the command

sudo mkdir -p /data/db/ and sudo chown id -u /data/db

then I run the mongo again and it worked.

In my case, adding the below meta tag solved the problem. I was using Arabic content and had to add this to make the image appear on WhatsApp:

<meta property='og:locale' content='ar_AR' />

Note: If you are using English content, no need to add this meta tag since English is the default value.

have you tried:

start "c:\program files\Microsoft Virtual PC\Virtual PC.exe" "-pc MY-PC -launch"

?

In case of multiple inheritance level, this function can be used as a super() method in other languages. Here is a demo fiddle, with some tests, you can use it like this, inside your method use : call_base(this, 'method_name', arguments);

It make use of quite recent ES functions, an compatibility with older browsers is not guarantee. Tested in IE11, FF29, CH35.

/**
 * Call super method of the given object and method.
 * This function create a temporary variable called "_call_base_reference",
 * to inspect whole inheritance linage. It will be deleted at the end of inspection.
 *
 * Usage : Inside your method use call_base(this, 'method_name', arguments);
 *
 * @param {object} object The owner object of the method and inheritance linage
 * @param {string} method The name of the super method to find.
 * @param {array} args The calls arguments, basically use the "arguments" special variable.
 * @returns {*} The data returned from the super method.
 */
function call_base(object, method, args) {
    // We get base object, first time it will be passed object,
    // but in case of multiple inheritance, it will be instance of parent objects.
    var base = object.hasOwnProperty('_call_base_reference') ? object._call_base_reference : object,
    // We get matching method, from current object,
    // this is a reference to define super method.
            object_current_method = base[method],
    // Temp object wo receive method definition.
            descriptor = null,
    // We define super function after founding current position.
            is_super = false,
    // Contain output data.
            output = null;
    while (base !== undefined) {
        // Get method info
        descriptor = Object.getOwnPropertyDescriptor(base, method);
        if (descriptor !== undefined) {
            // We search for current object method to define inherited part of chain.
            if (descriptor.value === object_current_method) {
                // Further loops will be considered as inherited function.
                is_super = true;
            }
            // We already have found current object method.
            else if (is_super === true) {
                // We need to pass original object to apply() as first argument,
                // this allow to keep original instance definition along all method
                // inheritance. But we also need to save reference to "base" who
                // contain parent class, it will be used into this function startup
                // to begin at the right chain position.
                object._call_base_reference = base;
                // Apply super method.
                output = descriptor.value.apply(object, args);
                // Property have been used into super function if another
                // call_base() is launched. Reference is not useful anymore.
                delete object._call_base_reference;
                // Job is done.
                return output;
            }
        }
        // Iterate to the next parent inherited.
        base = Object.getPrototypeOf(base);
    }
}

You can work out the columns that are only in one DataFrame and use this to select a subset of columns in the merge.

cols_to_use = df2.columns.difference(df.columns)

Then perform the merge (note this is an index object but it has a handy tolist() method).

dfNew = merge(df, df2[cols_to_use], left_index=True, right_index=True, how='outer')

This will avoid any columns clashing in the merge.

It means somewhere in your chain of calls, you tried to access a Property or call a method on an object that was null.

Given your statement:

img1.ImageUrl = ConfigurationManager
                    .AppSettings
                    .Get("Url")
                    .Replace("###", randomString) 
                + Server.UrlEncode(
                      ((System.Web.UI.MobileControls.Form)Page
                      .FindControl("mobileForm"))
                      .Title);

I'm guessing either the call to AppSettings.Get("Url") is returning null because the value isn't found or the call to Page.FindControl("mobileForm") is returning null because the control isn't found.

You could easily break this out into multiple statements to solve the problem:

var configUrl = ConfigurationManager.AppSettings.Get("Url");
var mobileFormControl = Page.FindControl("mobileForm")
                            as System.Web.UI.MobileControls.Form;

if(configUrl != null && mobileFormControl != null)
{
    img1.ImageUrl = configUrl.Replace("###", randomString) + mobileControl.Title;
}

install by this command given below conda install -c conda-forge keras

this is error "CondaError: Cannot link a source that does not exist" ive get in win 10. for your error put this command in your command line.

conda update conda

this work for me .

In PHP 5+ objects are passed by reference. In PHP 4 they are passed by value (that's why it had runtime pass by reference, which became deprecated).

You can use the 'clone' operator in PHP5 to copy objects:

$objectB = clone $objectA;

Also, it's just objects that are passed by reference, not everything as you've said in your question...

You can try something like:

var str = "a,d,k";
str.replace(/,/g, "");

Solved issue using below steps :

1) edit file "/etc/apache2/sites-enabled/000-default.conf"

The command :hide will hide the currently focused window. I think this is the functionality you are looking for.

In order to navigate between windows type Ctrl+w followed by a navigation key (h,j,k,l, or arrow keys)

For more information run :help window and :help hide in vim.

<< is a binary shift, shifting 1 to the left 8 places.

4'b0001 << 1 => 4'b0010

>> is a binary right shift adding 0's to the MSB.
>>> is a signed shift which maintains the value of the MSB if the left input is signed.

4'sb1011 >>  1 => 0101
4'sb1011 >>> 1 => 1101

Three ways to indicate left operand is signed:

module shift;
  logic        [3:0] test1 = 4'b1000;
  logic signed [3:0] test2 = 4'b1000;

  initial begin
    $display("%b", $signed(test1) >>> 1 ); //Explicitly set as signed
    $display("%b", test2          >>> 1 ); //Declared as signed type
    $display("%b", 4'sb1000       >>> 1 ); //Signed constant
    $finish;
  end
endmodule

I did git reset --hard on the wrong project by mistake (I know...). I had just worked on one file and it was still open during and after I ran the command.

Even though I had not committed, I was able to retrieve the old file with the simple COMMAND + Z.

No, Not at all.

Callbacks are simply Functions In JavaScript which are to be called and then executed after the execution of another function has finished. So how it happens?

Actually, In JavaScript, functions are itself considered as objects and hence as all other objects, even functions can be sent as arguments to other functions. The most common and generic use case one can think of is setTimeout() function in JavaScript.

Promises are nothing but a much more improvised approach of handling and structuring asynchronous code in comparison to doing the same with callbacks.

The Promise receives two Callbacks in constructor function: resolve and reject. These callbacks inside promises provide us with fine-grained control over error handling and success cases. The resolve callback is used when the execution of promise performed successfully and the reject callback is used to handle the error cases.

Two approaches that come to mind:

>>> df
          A         B         C         D
0  0.424634  1.716633  0.282734  2.086944
1 -1.325816  2.056277  2.583704 -0.776403
2  1.457809 -0.407279 -1.560583 -1.316246
3 -0.757134 -1.321025  1.325853 -2.513373
4  1.366180 -1.265185 -2.184617  0.881514
>>> df.iloc[:, 2]
0    0.282734
1    2.583704
2   -1.560583
3    1.325853
4   -2.184617
Name: C
>>> df[df.columns[2]]
0    0.282734
1    2.583704
2   -1.560583
3    1.325853
4   -2.184617
Name: C

Edit: The original answer suggested the use of df.ix[:,2] but this function is now deprecated. Users should switch to df.iloc[:,2].

If you want to understand AutoResetEvent and ManualResetEvent you need to understand not threading but interrupts!

.NET wants to conjure up low-level programming the most distant possible.

An interrupts is something used in low-level programming which equals to a signal that from low became high (or viceversa). When this happens the program interrupt its normal execution and move the execution pointer to the function that handles this event.

The first thing to do when an interrupt happend is to reset its state, becosa the hardware works in this way:

1. a pin is connected to a signal and the hardware listen for it to change (the signal could have only two states).
2. if the signal changes means that something happened and the hardware put a memory variable to the state happened (and it remain like this even if the signal change again).
3. the program notice that variable change states and move the execution to a handling function.
4. here the first thing to do, to be able to listen again this interrupt, is to reset this memory variable to the state not-happened.

This is the difference between ManualResetEvent and AutoResetEvent.
If a ManualResetEvent happen and I do not reset it, the next time it happens I will not be able to listen it.

Here is an alternative method using ls:

(ls x.txt && echo yes) || echo no

If you want to hide any output from ls so you only see yes or no, redirect stdout and stderr to /dev/null:

(ls x.txt >> /dev/null 2>&1 && echo yes) || echo no

Using React Hooks and the useRef hook.

import React, { useRef } from 'react';

const MyComponent = () => {
    const myInput = useRef(null);

    const clickElement = () => {
        // To simulate a user focusing an input you should use the
        // built in .focus() method.
        myInput.current?.focus();

        // To simulate a click on a button you can use the .click()
        // method.
        // myInput.current?.click();
    }

    return (
        <div>
            <button onClick={clickElement}>
                Trigger click inside input
            </button>
            <input ref={myInput} />
        </div>
    );
}

Try this

 String str="10,692,467,440,017.120".replaceAll(",","");
 BigDecimal bd=new BigDecimal(str);

As a sure method way, you can just make a background image that is say 500x5 pixels, in your css use:

background-img:url(bg.jpg) fixed repeat-x;
background:#<xxxxxx>;

Where xxxxxx corresponds with the color that matches the final gradient color.

You could also fix this to the bottom of the screen and have it match the initial gradient color.

Complete code with error handling and added file stream closes. Add it to your class that you want to be able to serialize and deserialize. In my case the class name is CreateResumeForm. You should change it to your own class name. Android interface Serializable is not sufficient to save your objects to the file, it only creates streams.

// Constant with a file name
public static String fileName = "createResumeForm.ser";

// Serializes an object and saves it to a file
public void saveToFile(Context context) {
    try {
        FileOutputStream fileOutputStream = context.openFileOutput(fileName, Context.MODE_PRIVATE);
        ObjectOutputStream objectOutputStream = new ObjectOutputStream(fileOutputStream);
        objectOutputStream.writeObject(this);
        objectOutputStream.close();
        fileOutputStream.close();
    } catch (IOException e) {
        e.printStackTrace();
    }
}


// Creates an object by reading it from a file
public static CreateResumeForm readFromFile(Context context) {
    CreateResumeForm createResumeForm = null;
    try {
        FileInputStream fileInputStream = context.openFileInput(fileName);
        ObjectInputStream objectInputStream = new ObjectInputStream(fileInputStream);
        createResumeForm = (CreateResumeForm) objectInputStream.readObject();
        objectInputStream.close();
        fileInputStream.close();
    } catch (IOException e) {
        e.printStackTrace();
    }
    catch (ClassNotFoundException e) {
        e.printStackTrace();
    }
    return createResumeForm;
}

Use it like this in your Activity:

form = CreateResumeForm.readFromFile(this);

The following steps work fine on macOS Sierra 10.12.4. Note that after brew installs Docker, the docker command (symbolic link) is not available at /usr/local/bin. Running the Docker app for the first time creates this symbolic link. See the detailed steps below.

1. Install Docker.

   brew cask install docker
   

2. Launch Docker.

   • Press ? + Space to bring up Spotlight Search and enter Docker to launch Docker.
   • In the Docker needs privileged access dialog box, click OK.
   • Enter password and click OK.

   When Docker is launched in this manner, a Docker whale icon appears in the status menu. As soon as the whale icon appears, the symbolic links for docker, docker-compose, docker-credential-osxkeychain and docker-machine are created in /usr/local/bin.

   $ ls -l /usr/local/bin/docker*
   lrwxr-xr-x  1 susam  domain Users  67 Apr 12 14:14 /usr/local/bin/docker -> /Users/susam/Library/Group Containers/group.com.docker/bin/docker
   lrwxr-xr-x  1 susam  domain Users  75 Apr 12 14:14 /usr/local/bin/docker-compose -> /Users/susam/Library/Group Containers/group.com.docker/bin/docker-compose
   lrwxr-xr-x  1 susam  domain Users  90 Apr 12 14:14 /usr/local/bin/docker-credential-osxkeychain -> /Users/susam/Library/Group Containers/group.com.docker/bin/docker-credential-osxkeychain
   lrwxr-xr-x  1 susam  domain Users  75 Apr 12 14:14 /usr/local/bin/docker-machine -> /Users/susam/Library/Group Containers/group.com.docker/bin/docker-machine
   

3. Click on the docker whale icon in the status menu and wait for it to show Docker is running.

   

4. Test that docker works fine.

   $ docker run hello-world
   Unable to find image 'hello-world:latest' locally
   latest: Pulling from library/hello-world

   Status: Downloaded newer image for hello-world:latest
   
   Hello from Docker!
   This message shows that your installation appears to be working correctly.
   
   To generate this message, Docker took the following steps:
    1. The Docker client contacted the Docker daemon.
    2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
    3. The Docker daemon created a new container from that image which runs the
       executable that produces the output you are currently reading.
    4. The Docker daemon streamed that output to the Docker client, which sent it
       to your terminal.
   
   To try something more ambitious, you can run an Ubuntu container with:
    $ docker run -it ubuntu bash

5. If you are going to use docker-machine to create virtual machines, install VirtualBox.

   brew cask install virtualbox
   

   Note that if VirtualBox is not installed, then docker-machine fails with the following error.

   $ docker-machine create manager
   Running pre-create checks...
   Error with pre-create check: "VBoxManage not found. Make sure VirtualBox is installed and VBoxManage is in the path"
   

you seem to have not created an main method, which should probably look something like this (i am not sure)

  class RunThis
{
    public static void main(String[] args)
    {

    Calculate answer = new Calculate();
    answer.getNumber1();
    answer.getNumber2();
    answer.setNumber(answer.getNumber1() , answer.getNumber2());
    answer.getOper();
    answer.setOper(answer.getOper());
    answer.getAnswer();
    }
}

the point is you should have created a main method under some class and after compiling you should run the .class file containing main method. In this case the main method is under RunThis i.e RunThis.class.

I am new to java this may or may not be the right answer, correct me if i am wrong

print "Number of lines: $nids\n";
print "Content: $ids\n";

How did Perl complain? print $ids should work, though you probably want a newline at the end, either explicitly with print as above or implicitly by using say or -l/$\.

If you want to interpolate a variable in a string and have something immediately after it that would looks like part of the variable but isn't, enclose the variable name in {}:

print "foo${ids}bar";

A bit of explaining as to what that %2520 is :

The common space character is encoded as %20 as you noted yourself. The % character is encoded as %25.

The way you get %2520 is when your url already has a %20 in it, and gets urlencoded again, which transforms the %20 to %2520.

Are you (or any framework you might be using) double encoding characters?

Edit: Expanding a bit on this, especially for LOCAL links. Assuming you want to link to the resource C:\my path\my file.html:

• if you provide a local file path only, the browser is expected to encode and protect all characters given (in the above, you should give it with spaces as shown, since % is a valid filename character and as such it will be encoded) when converting to a proper URL (see next point).
• if you provide a URL with the file:// protocol, you are basically stating that you have taken all precautions and encoded what needs encoding, the rest should be treated as special characters. In the above example, you should thus provide file:///c:/my%20path/my%20file.html. Aside from fixing slashes, clients should not encode characters here.

NOTES:

• Slash direction - forward slashes / are used in URLs, reverse slashes \ in Windows paths, but most clients will work with both by converting them to the proper forward slash.
• In addition, there are 3 slashes after the protocol name, since you are silently referring to the current machine instead of a remote host ( the full unabbreviated path would be file://localhost/c:/my%20path/my%file.html ), but again most clients will work without the host part (ie two slashes only) by assuming you mean the local machine and adding the third slash.

On Arch Linux, the following works really great (should work on all systemd-based distros):

Create a systemd user service, by putting the following to ~/.config/systemd/user/ssh-agent.service:

[Unit]
Description=SSH key agent

[Service]
Type=simple
Environment=SSH_AUTH_SOCK=%t/ssh-agent.socket
ExecStart=/usr/bin/ssh-agent -D -a $SSH_AUTH_SOCK

[Install]
WantedBy=default.target

Setup shell to have an environment variable for the socket (.bash_profile, .zshrc, ...):

export SSH_AUTH_SOCK="$XDG_RUNTIME_DIR/ssh-agent.socket"

Enable the service, so it'll be started automatically on login, and start it:

systemctl --user enable ssh-agent
systemctl --user start ssh-agent

Add the following configuration setting to your local ssh config file ~/.ssh/config (this works since SSH 7.2):

AddKeysToAgent  yes

This will instruct the ssh client to always add the key to a running agent, so there's no need to ssh-add it beforehand.

Solution for Swift 4:

yourLabel.layer.borderColor = UIColor.green.cgColor

Reading the R language documentation, as.integer has more to do with how the number is stored than if it is practically equivalent to an integer. is.integer tests if the number is declared as an integer. You can declare an integer by putting a L after it.

> is.integer(66L)
[1] TRUE
> is.integer(66)
[1] FALSE

Also functions like round will return a declared integer, which is what you are doing with x==round(x). The problem with this approach is what you consider to be practically an integer. The example uses less precision for testing equivalence.

> is.wholenumber(1+2^-50)
[1] TRUE
> check.integer(1+2^-50)
[1] FALSE

So depending on your application you could get into trouble that way.

The general consensus is that you do not (should not) need to dispose of HttpClient.

Many people who are intimately involved in the way it works have stated this.

See Darrel Miller's blog post and a related SO post: HttpClient crawling results in memory leak for reference.

I'd also strongly suggest that you read the HttpClient chapter from Designing Evolvable Web APIs with ASP.NET for context on what is going on under the hood, particularly the "Lifecycle" section quoted here:

Although HttpClient does indirectly implement the IDisposable interface, the standard usage of HttpClient is not to dispose of it after every request. The HttpClient object is intended to live for as long as your application needs to make HTTP requests. Having an object exist across multiple requests enables a place for setting DefaultRequestHeaders and prevents you from having to re-specify things like CredentialCache and CookieContainer on every request as was necessary with HttpWebRequest.

Or even open up DotPeek.

• All my certificates are installed and expire dates are fine.
• I deleted and reinstalled all my certificates, still no luck

In the end, I right-clicked on the certificate, and selected "Get Info". Under the Trust section, I selected "Always Trust" and this solved my problem.

Your currently selected backend, 'agg' does not support show().

AGG backend is for writing to file, not for rendering in a window. See the backend FAQ at the matplotlib web site.

ImportError: No module named _backend_gdk

For the second error, maybe your matplotlib distribution is not compiled with GTK support, or you miss the PyGTK package. Try to install it.

Do you call the show() method inside a terminal or application that has access to a graphical environment?

Try other GUI backends, in this order:

• TkAgg
• WX
• QTAgg
• QT4Agg

We overflowed an integer primary key once (which is ~2.4 billion rows) on a table. If there's a row limit, you're not likely to ever hit it at a mere 36 million rows per year.

You should do this using jQuery.ajaxStart and jQuery.ajaxStop.

1. Create a div with your image
2. Make it visible in jQuery.ajaxStart
3. Hide it in jQuery.ajaxStop

Sample

<div id="loading" style="display:none">Your Image</div>

<script src="../../Scripts/jquery-1.5.1.min.js" type="text/javascript"></script>
<script>
    $(function () {
        var loading = $("#loading");
        $(document).ajaxStart(function () {
            loading.show();
        });

        $(document).ajaxStop(function () {
            loading.hide();
        });

        $("#startAjaxRequest").click(function () {
            $.ajax({
                url: "http://www.google.com",
                // ... 
            });
        });
    });
</script>

<button id="startAjaxRequest">Start</button>

Here are a couple functions I wrote to get a file in a json format which can be passed around easily:

    //takes an array of JavaScript File objects
    function getFiles(files) {
        return Promise.all(files.map(file => getFile(file)));
    }

    //take a single JavaScript File object
    function getFile(file) {
        var reader = new FileReader();
        return new Promise((resolve, reject) => {
            reader.onerror = () => { reader.abort(); reject(new Error("Error parsing file"));}
            reader.onload = function () {

                //This will result in an array that will be recognized by C#.NET WebApi as a byte[]
                let bytes = Array.from(new Uint8Array(this.result));

                //if you want the base64encoded file you would use the below line:
                let base64StringFile = btoa(bytes.map((item) => String.fromCharCode(item)).join(""));

                //Resolve the promise with your custom file structure
                resolve({ 
                    bytes: bytes,
                    base64StringFile: base64StringFile,
                    fileName: file.name, 
                    fileType: file.type
                });
            }
            reader.readAsArrayBuffer(file);
        });
    }

    //using the functions with your file:

    file = document.querySelector('#files > input[type="file"]').files[0]
    getFile(file).then((customJsonFile) => {
         //customJsonFile is your newly constructed file.
         console.log(customJsonFile);
    });

    //if you are in an environment where async/await is supported

    files = document.querySelector('#files > input[type="file"]').files
    let customJsonFiles = await getFiles(files);
    //customJsonFiles is an array of your custom files
    console.log(customJsonFiles);

The above method works good.

Another method (I am assuming web here) is to create your page. Add controls to the page. Then while in design mode go to: Tools > Generate Local Resource. A resource file will automatically appear in the solution with all the controls in the page mapped in the resource file.

To create resources for other languages, append the 4 character language to the end of the file name, before the extension (Account.aspx.en-US.resx, Account.aspx.es-ES.resx...etc).

To retrieve specific entries in the code-behind, simply call this method: GetLocalResourceObject([resource entry key/name]).

If you are actually looking for Charting libraries and not for Node/Edge Graph libraries I would suggest splurging on Big Faceless Graph library (BFG). It's way easier to use than JFreeChart, looks nicer, runs faster, has more output options, really no comparison.

Read the message:

Only one <configSections> element allowed per config file and if present must be the first child of the root <configuration> element.

Move the configSections element to the top - just above where system.data is currently.

// sample C#
public void populateButtons()
{
    int xPos;
    int yPos;

    Random ranNum = new Random();

    for (int i = 0; i < 50; i++)
    {
        Button foo = new Button();
        Style buttonStyle = Window.Resources["CurvedButton"] as Style;

        int sizeValue = ranNum.Next(50);

        foo.Width = sizeValue;
        foo.Height = sizeValue;
        foo.Name = "button" + i;

        xPos = ranNum.Next(300);
        yPos = ranNum.Next(200);

        foo.HorizontalAlignment = HorizontalAlignment.Left;
        foo.VerticalAlignment = VerticalAlignment.Top;
        foo.Margin = new Thickness(xPos, yPos, 0, 0);

        foo.Style = buttonStyle;

        foo.Click += new RoutedEventHandler(buttonClick);
        LayoutRoot.Children.Add(foo);
   }
}

private void buttonClick(object sender, EventArgs e)
{
  //do something or...
  Button clicked = (Button) sender;
  MessageBox.Show("Button's name is: " + clicked.Name);
}

Personally, I would shorten it a touch too if all you need is the columns:

For i = LBound(arr1) To UBound(arr1)
    Sheets("SheetA").Columns(arr1(i)).Copy
    Sheets("SheetB").Columns(arr2(i)).PasteSpecial xlPasteValues
    Application.CutCopyMode = False
Next

as from this code snippet, there isnt much point in lastrow or firstrowDB

Here's an example.

In CSS (used to style HTML pages), if you want an image element to be 100 pixels high and 100 pixels wide, you simply "declare" that that's what you want as follows:

#myImageId {
height: 100px;
width: 100px;
}

You can consider CSS a declarative "style sheet" language.

The browser engine that reads and interprets this CSS is free to make the image appear this tall and this wide however it wants. Different browser engines (e.g., the engine for IE, the engine for Chrome) will implement this task differently.

Their unique implementations are, of course, NOT written in a declarative language but in a procedural one like Assembly, C, C++, Java, JavaScript, or Python. That code is a bunch of steps to be carried out step by step (and might include function calls). It might do things like interpolate pixel values, and render on the screen.

I target the 1024 pixel monitors (but don't use 100% of that space). I've given up on those with 800x600. I'd rather punish the few with outdated hardware by making them scroll if they need to, versus punishing everyone with new equipment by wasting space.

I suppose it depends on your audience, and the nature of you app though.

Not necessarily true. It will be encrypted on the wire however it still lands in the logs plain text

first get the ObjectID function from the mongodb ObjectId = require(mongodb).ObjectID;

then you can call the _id with the delete function

"_id" : ObjectId("4d5192665777000000005490")

If you're still having trouble even after configuring your package.json according to the documentation (if you've opted to use package.json to track rather than separate config files):

"rules": {
      "no-console": "off"
    },

And it still isn't working for you, don't forget you need to go back to the command line and do npm install again. :)

Here's a simple example of how to load JSON data into an Angular model.

I have a JSON 'GET' web service which returns a list of Customer details, from an online copy of Microsoft's Northwind SQL Server database.

http://www.iNorthwind.com/Service1.svc/getAllCustomers

It returns some JSON data which looks like this:

{ 
    "GetAllCustomersResult" : 
        [
            {
              "CompanyName": "Alfreds Futterkiste",
              "CustomerID": "ALFKI"
            },
            {
              "CompanyName": "Ana Trujillo Emparedados y helados",
              "CustomerID": "ANATR"
            },
            {
              "CompanyName": "Antonio Moreno Taquería",
              "CustomerID": "ANTON"
            }
        ]
    }

..and I want to populate a drop down list with this data, to look like this...

I want the text of each item to come from the "CompanyName" field, and the ID to come from the "CustomerID" fields.

How would I do it ?

My Angular controller would look like this:

function MikesAngularController($scope, $http) {

    $scope.listOfCustomers = null;

    $http.get('http://www.iNorthwind.com/Service1.svc/getAllCustomers')
         .success(function (data) {
             $scope.listOfCustomers = data.GetAllCustomersResult;
         })
         .error(function (data, status, headers, config) {
             //  Do some error handling here
         });
}

... which fills a "listOfCustomers" variable with this set of JSON data.

Then, in my HTML page, I'd use this:

<div ng-controller='MikesAngularController'>
    <span>Please select a customer:</span>
    <select ng-model="selectedCustomer" ng-options="customer.CustomerID as customer.CompanyName for customer in listOfCustomers" style="width:350px;"></select>
</div>

And that's it. We can now see a list of our JSON data on a web page, ready to be used.

The key to this is in the "ng-options" tag:

customer.CustomerID as customer.CompanyName for customer in listOfCustomers

It's a strange syntax to get your head around !

When the user selects an item in this list, the "$scope.selectedCustomer" variable will be set to the ID (the CustomerID field) of that Customer record.

The full script for this example can be found here:

I created a function to check if times in an array overlap somehow:

    /**
     * Function to check if there are overlapping times in an array of \DateTime objects.
     *
     * @param $ranges
     *
     * @return \DateTime[]|bool
     */
    public function timesOverlap($ranges) {
        foreach ($ranges as $k1 => $t1) {
            foreach ($ranges as $k2 => $t2) {
                if ($k1 != $k2) {
                    /* @var \DateTime[] $t1 */
                    /* @var \DateTime[] $t2 */
                    $a = $t1[0]->getTimestamp();
                    $b = $t1[1]->getTimestamp();
                    $c = $t2[0]->getTimestamp();
                    $d = $t2[1]->getTimestamp();

                    if (($c >= $a && $c <= $b) || $d >= $a && $d <= $b) {
                        return true;
                    }
                }
            }
        }

        return false;
    }

you can use online library

SIMPLE WAY TO CONNECT

1) You'll have to verify authentication

from google.colab import auth
auth.authenticate_user()
from oauth2client.client import GoogleCredentials
creds = GoogleCredentials.get_application_default()

2)To fuse google drive

!apt-get install -y -qq software-properties-common python-software-properties module-init-tools
!add-apt-repository -y ppa:alessandro-strada/ppa 2>&1 > /dev/null
!apt-get update -qq 2>&1 > /dev/null
!apt-get -y install -qq google-drive-ocamlfuse fuse

3)To verify credentials

import getpass
!google-drive-ocamlfuse -headless -id={creds.client_id} -secret={creds.client_secret} < /dev/null 2>&1 | grep URL
vcode = getpass.getpass()
!echo {vcode} | google-drive-ocamlfuse -headless -id={creds.client_id} -secret={creds.client_secret}

4)Create a drive name to use it in colab ('gdrive') and check if it's working

!mkdir gdrive
!google-drive-ocamlfuse gdrive
!ls gdrive
!cd gdrive

This works for me (mostly).

Put this at the bottom of your page.

<script type="application/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js">
</script>

<script type="application/javascript" src="/script/jquery.browser.js">
</script>

<script type="application/javascript" src="/script/jquery-iframe-auto-height.js">
</script>

<script type="application/javascript"> 
  jQuery('iframe').iframeAutoHeight();
  $(window).load(
      function() {
          jQuery('iframe').iframeAutoHeight();  
      }
  );

  // for when content is not html e.g. a PDF
  function setIframeHeight() {
      $('.iframe_fullHeight').each(
          function (i, item) {
              item.height = $(document).height();
          }
      );
  };

  $(document).ready( function () {
      setIframeHeight();
  });
  $(window).resize( function () {
      setIframeHeight();
  });
</script> 

The first half is from ???, and works when there is html in the iframe. The second half sets the iframe to page height (not content height), when iframes class is iframe_fullHeight. You can use this if the content is a PDF or other such like, but you have to set the class. Also can only be used when being full height is appropriate.

Note: for some reason, when it recalculates after window resize, it gets height wrong.

1. Modify string to separate each character using a separator[this is to incorporate odd and even palindromes]
2. Find palindromes around each character treating it as a center

We can find all palindromes of all length using this.

Sample :

word = abcdcbc

modifiedString = a#b#c#d#c#b#c

palinCount = 1010105010301

length of longest palindrome = 5;

longest palindrome = bcdcb

public class MyLongestPalindrome {

static String word;
static int wordlength;
static int highestcount = 0;
static int newlength;
static char[] modifiedString; // stores modified string
static int[] palinCount; // stores palindrome length at each position
static char pound = '#';

public static void main(String[] args) throws IOException {
    // TODO Auto-generated method stub
    System.out.println("Enter String : ");
    InputStreamReader isr = new InputStreamReader(System.in);
    BufferedReader bfr = new BufferedReader(isr);
    word = bfr.readLine();
    wordlength = word.length();
    newlength = (wordlength * 2) - 1;
    convert();
    findpalindrome();
    display();
}

// Inserting # in string
public static void convert() {

    modifiedString = new char[newlength];
    int j = 0;
    int i;
    for (i = 0; i < wordlength - 1; i++) {
        modifiedString[j++] = word.charAt(i);
        modifiedString[j++] = pound;
    }
    modifiedString[j] = word.charAt(i);
}

// display all palindromes of highest length
public static void display() {
    String palindrome;
    String s = new String(modifiedString);
    System.out.println("Length of longest palindrome = " + highestcount);
    for (int i = 0; i < newlength; i++) {
        if (palinCount[i] == highestcount) {
            palindrome = s.substring(i - (highestcount - 1), i
                    + (highestcount));
            i = i + (highestcount - 1);
            palindrome = palindrome.replace("#", "");
            System.out.println(palindrome);
        }
    }
}

// populate palinCount with length of palindrome string at each position
public static void findpalindrome() {
    int left, right, count;
    palinCount = new int[newlength];
    palinCount[0] = 1;
    palinCount[newlength - 1] = 1;
    for (int i = 1; i < newlength - 1; i++) {
        count = 0;
        left = i - 1;
        right = i + 1;
        ;
        if (modifiedString[i] != pound)
            count++;
        while (left >= 0 && right < newlength) {
            if (modifiedString[left] == modifiedString[right]) {
                if (modifiedString[left] != pound)
                    count = count + 2;
                left--;
                right++;
            } else
                break;
        }

        palinCount[i] = count;
        highestcount = count > highestcount ? count : highestcount;

    }

}

}

I solved this issue following the indication provided in the article http://blog.dev-area.net/2015/08/13/android-4-1-enable-tls-1-1-and-tls-1-2/ with little changes.

SSLContext context = SSLContext.getInstance("TLS");
context.init(null, null, null);
SSLSocketFactory noSSLv3Factory = null;
if (Build.VERSION.SDK_INT <= Build.VERSION_CODES.KITKAT) {
    noSSLv3Factory = new TLSSocketFactory(sslContext.getSocketFactory());
} else {
    noSSLv3Factory = sslContext.getSocketFactory();
}
connection.setSSLSocketFactory(noSSLv3Factory);

This is the code of the custom TLSSocketFactory:

public static class TLSSocketFactory extends SSLSocketFactory {

    private SSLSocketFactory internalSSLSocketFactory;

    public TLSSocketFactory(SSLSocketFactory delegate) throws KeyManagementException, NoSuchAlgorithmException {
        internalSSLSocketFactory = delegate;
    }

    @Override
    public String[] getDefaultCipherSuites() {
        return internalSSLSocketFactory.getDefaultCipherSuites();
    }

    @Override
    public String[] getSupportedCipherSuites() {
        return internalSSLSocketFactory.getSupportedCipherSuites();
    }

    @Override
    public Socket createSocket(Socket s, String host, int port, boolean autoClose) throws IOException {
        return enableTLSOnSocket(internalSSLSocketFactory.createSocket(s, host, port, autoClose));
    }

    @Override
    public Socket createSocket(String host, int port) throws IOException, UnknownHostException {
        return enableTLSOnSocket(internalSSLSocketFactory.createSocket(host, port));
    }

    @Override
    public Socket createSocket(String host, int port, InetAddress localHost, int localPort) throws IOException, UnknownHostException {
        return enableTLSOnSocket(internalSSLSocketFactory.createSocket(host, port, localHost, localPort));
    }

    @Override
    public Socket createSocket(InetAddress host, int port) throws IOException {
        return enableTLSOnSocket(internalSSLSocketFactory.createSocket(host, port));
    }

    @Override
    public Socket createSocket(InetAddress address, int port, InetAddress localAddress, int localPort) throws IOException {
        return enableTLSOnSocket(internalSSLSocketFactory.createSocket(address, port, localAddress, localPort));
    }

    /*
     * Utility methods
     */

    private static Socket enableTLSOnSocket(Socket socket) {
        if (socket != null && (socket instanceof SSLSocket)
                && isTLSServerEnabled((SSLSocket) socket)) { // skip the fix if server doesn't provide there TLS version
            ((SSLSocket) socket).setEnabledProtocols(new String[]{TLS_v1_1, TLS_v1_2});
        }
        return socket;
    }

    private static boolean isTLSServerEnabled(SSLSocket sslSocket) {
        System.out.println("__prova__ :: " + sslSocket.getSupportedProtocols().toString());
        for (String protocol : sslSocket.getSupportedProtocols()) {
            if (protocol.equals(TLS_v1_1) || protocol.equals(TLS_v1_2)) {
                return true;
            }
        }
        return false;
    }
}

Edit: Thank's to ademar111190 for the kotlin implementation (link)

class TLSSocketFactory constructor(
        private val internalSSLSocketFactory: SSLSocketFactory
) : SSLSocketFactory() {

    private val protocols = arrayOf("TLSv1.2", "TLSv1.1")

    override fun getDefaultCipherSuites(): Array<String> = internalSSLSocketFactory.defaultCipherSuites

    override fun getSupportedCipherSuites(): Array<String> = internalSSLSocketFactory.supportedCipherSuites

    override fun createSocket(s: Socket, host: String, port: Int, autoClose: Boolean) =
            enableTLSOnSocket(internalSSLSocketFactory.createSocket(s, host, port, autoClose))

    override fun createSocket(host: String, port: Int) =
            enableTLSOnSocket(internalSSLSocketFactory.createSocket(host, port))

    override fun createSocket(host: String, port: Int, localHost: InetAddress, localPort: Int) =
            enableTLSOnSocket(internalSSLSocketFactory.createSocket(host, port, localHost, localPort))

    override fun createSocket(host: InetAddress, port: Int) =
            enableTLSOnSocket(internalSSLSocketFactory.createSocket(host, port))

    override fun createSocket(address: InetAddress, port: Int, localAddress: InetAddress, localPort: Int) =
            enableTLSOnSocket(internalSSLSocketFactory.createSocket(address, port, localAddress, localPort))

    private fun enableTLSOnSocket(socket: Socket?) = socket?.apply {
        if (this is SSLSocket && isTLSServerEnabled(this)) {
            enabledProtocols = protocols
        }
    }

    private fun isTLSServerEnabled(sslSocket: SSLSocket) = sslSocket.supportedProtocols.any { it in protocols }

}

C# 7 tuple example

var tuple = TupleExample(key, value);

     private (string key1, long value1) ValidateAPIKeyOwnerId(string key, string value)
            {
                return (key, value);
            }
      if (!string.IsNullOrEmpty(tuple.key1) && tuple.value1 > 0)
          {
                    //your code

                }     

1. Normal Class: A Java class

2. Java Beans:

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

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

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

use this if your email column contains empty values

 select * from table where email in (
    select email from table group by email having count(*) > 1 and email != ''
    )

That is very odd.

I went through ItemNotFoundException's base classes and tested the following multiple catches to see what would catch it:

try {
  remove-item C:\nonexistent\file.txt -erroraction stop
}
catch [System.Management.Automation.ItemNotFoundException] {
  write-host 'ItemNotFound'
}
catch [System.Management.Automation.SessionStateException] {
  write-host 'SessionState'
}
catch [System.Management.Automation.RuntimeException] {
  write-host 'RuntimeException'
}
catch [System.SystemException] {
  write-host 'SystemException'
}
catch [System.Exception] {
  write-host 'Exception'
}
catch {
  write-host 'well, darn'
}

As it turns out, the output was 'RuntimeException'. I also tried it with a different exception CommandNotFoundException:

try {
  do-nonexistent-command
}
catch [System.Management.Automation.CommandNotFoundException] {
  write-host 'CommandNotFoundException'
}
catch {
  write-host 'well, darn'
}

That output 'CommandNotFoundException' correctly.

I vaguely remember reading elsewhere (though I couldn't find it again) of problems with this. In such cases where exception filtering didn't work correctly, they would catch the closest Type they could and then use a switch. The following just catches Exception instead of RuntimeException, but is the switch equivalent of my first example that checks all base types of ItemNotFoundException:

try {
  Remove-Item C:\nonexistent\file.txt -ErrorAction Stop
}
catch [System.Exception] {
  switch($_.Exception.GetType().FullName) {
    'System.Management.Automation.ItemNotFoundException' {
      write-host 'ItemNotFound'
    }
    'System.Management.Automation.SessionStateException' {
      write-host 'SessionState'
    }
    'System.Management.Automation.RuntimeException' {
      write-host 'RuntimeException'
    }
    'System.SystemException' {
      write-host 'SystemException'
    }
    'System.Exception' {
      write-host 'Exception'
    }
    default {'well, darn'}
  }
}

This writes 'ItemNotFound', as it should.

$.each(["input[type=text][value=]", "textarea[value=]"], function (index, element) {
              //only empty input and textarea will come here
});

I only just wrote it for another issue and thought it may help either of you as well.

Usage:

• i.e. onclick="_DOM_Trackr(this);"

Parameters:

1. DOM-Object to trace
2. return/alert switch (optional, default=alert)

Source-Code:

function _DOM_Trackr(_elem,retn=false)
{
    var pathTrackr='';
    var $self=$(_elem).get(0);
    while($self && $self.tagName)
    {
        var $id=($($self).attr("id"))?('#'+$($self).attr("id")):'';
        var $nName=$self.tagName;
        pathTrackr=($nName.toLowerCase())+$id+((pathTrackr=='')?'':' > '+(pathTrackr));
        $self=$($self).parent().get(0);
    }
    if (retn)
    {
        return pathTrackr;
    }
    else
    {
        alert(pathTrackr);
    }
}

Here's how to do this with java.nio operations:

public static void copyFile(File sourceFile, File destFile) throws IOException {
    if(!destFile.exists()) {
        destFile.createNewFile();
    }

    FileChannel source = null;
    FileChannel destination = null;
    try {
        source = new FileInputStream(sourceFile).getChannel();
        destination = new FileOutputStream(destFile).getChannel();

        // previous code: destination.transferFrom(source, 0, source.size());
        // to avoid infinite loops, should be:
        long count = 0;
        long size = source.size();              
        while((count += destination.transferFrom(source, count, size-count))<size);
    }
    finally {
        if(source != null) {
            source.close();
        }
        if(destination != null) {
            destination.close();
        }
    }
}

if the last element type is article too, last-of-type will not work as expected.

maybe i not really understand how it work.

demo

If you aren't dynamically loading scripts or marking them as defer or async, then scripts are loaded in the order encountered in the page. It doesn't matter whether it's an external script or an inline script - they are executed in the order they are encountered in the page. Inline scripts that come after external scripts are held until all external scripts that came before them have loaded and run.

Async scripts (regardless of how they are specified as async) load and run in an unpredictable order. The browser loads them in parallel and it is free to run them in whatever order it wants.

There is no predictable order among multiple async things. If one needed a predictable order, then it would have to be coded in by registering for load notifications from the async scripts and manually sequencing javascript calls when the appropriate things are loaded.

When a script tag is inserted dynamically, how the execution order behaves will depend upon the browser. You can see how Firefox behaves in this reference article. In a nutshell, the newer versions of Firefox default a dynamically added script tag to async unless the script tag has been set otherwise.

A script tag with async may be run as soon as it is loaded. In fact, the browser may pause the parser from whatever else it was doing and run that script. So, it really can run at almost any time. If the script was cached, it might run almost immediately. If the script takes awhile to load, it might run after the parser is done. The one thing to remember with async is that it can run anytime and that time is not predictable.

A script tag with defer waits until the entire parser is done and then runs all scripts marked with defer in the order they were encountered. This allows you to mark several scripts that depend upon one another as defer. They will all get postponed until after the document parser is done, but they will execute in the order they were encountered preserving their dependencies. I think of defer like the scripts are dropped into a queue that will be processed after the parser is done. Technically, the browser may be downloading the scripts in the background at any time, but they won't execute or block the parser until after the parser is done parsing the page and parsing and running any inline scripts that are not marked defer or async.

Here's a quote from that article:

script-inserted scripts execute asynchronously in IE and WebKit, but synchronously in Opera and pre-4.0 Firefox.

The relevant part of the HTML5 spec (for newer compliant browsers) is here. There is a lot written in there about async behavior. Obviously, this spec doesn't apply to older browsers (or mal-conforming browsers) whose behavior you would probably have to test to determine.

A quote from the HTML5 spec:

Then, the first of the following options that describes the situation must be followed:

If the element has a src attribute, and the element has a defer attribute, and the element has been flagged as "parser-inserted", and the element does not have an async attribute The element must be added to the end of the list of scripts that will execute when the document has finished parsing associated with the Document of the parser that created the element.

The task that the networking task source places on the task queue once the fetching algorithm has completed must set the element's "ready to be parser-executed" flag. The parser will handle executing the script.

If the element has a src attribute, and the element has been flagged as "parser-inserted", and the element does not have an async attribute The element is the pending parsing-blocking script of the Document of the parser that created the element. (There can only be one such script per Document at a time.)

The task that the networking task source places on the task queue once the fetching algorithm has completed must set the element's "ready to be parser-executed" flag. The parser will handle executing the script.

If the element does not have a src attribute, and the element has been flagged as "parser-inserted", and the Document of the HTML parser or XML parser that created the script element has a style sheet that is blocking scripts The element is the pending parsing-blocking script of the Document of the parser that created the element. (There can only be one such script per Document at a time.)

Set the element's "ready to be parser-executed" flag. The parser will handle executing the script.

If the element has a src attribute, does not have an async attribute, and does not have the "force-async" flag set The element must be added to the end of the list of scripts that will execute in order as soon as possible associated with the Document of the script element at the time the prepare a script algorithm started.

The task that the networking task source places on the task queue once the fetching algorithm has completed must run the following steps:

If the element is not now the first element in the list of scripts that will execute in order as soon as possible to which it was added above, then mark the element as ready but abort these steps without executing the script yet.

Execution: Execute the script block corresponding to the first script element in this list of scripts that will execute in order as soon as possible.

Remove the first element from this list of scripts that will execute in order as soon as possible.

If this list of scripts that will execute in order as soon as possible is still not empty and the first entry has already been marked as ready, then jump back to the step labeled execution.

If the element has a src attribute The element must be added to the set of scripts that will execute as soon as possible of the Document of the script element at the time the prepare a script algorithm started.

The task that the networking task source places on the task queue once the fetching algorithm has completed must execute the script block and then remove the element from the set of scripts that will execute as soon as possible.

Otherwise The user agent must immediately execute the script block, even if other scripts are already executing.

What about Javascript module scripts, type="module"?

Javascript now has support for module loading with syntax like this:

<script type="module">
  import {addTextToBody} from './utils.mjs';

  addTextToBody('Modules are pretty cool.');
</script>

Or, with src attribute:

<script type="module" src="http://somedomain.com/somescript.mjs">
</script>

All scripts with type="module" are automatically given the defer attribute. This downloads them in parallel (if not inline) with other loading of the page and then runs them in order, but after the parser is done.

Module scripts can also be given the async attribute which will run inline module scripts as soon as possible, not waiting until the parser is done and not waiting to run the async script in any particular order relative to other scripts.

There's a pretty useful timeline chart that shows fetch and execution of different combinations of scripts, including module scripts here in this article: Javascript Module Loading.

I too had this problem. My solution was:

sc.setSoLinger(true, 10);

COPY FROM A WEBSITE -->By using the setSoLinger() method, you can explicitly set a delay before a reset is sent, giving more time for data to be read or send.

Maybe it is not the answer to everybody but to some people.

There's no need to manually put class files on Tomcat. Just make sure your package declaration for Member is correctly defined as

package pageNumber;

since, that's the only application package you're importing in your JSP.

<%@ page import="pageNumber.*, java.util.*, java.io.*" %>

Step 1 – Check the DB listener status

   lsnrctl status

Notice that the listener you want (in our case “orcl”) is not showing.

Step 2 – Login via sqlplus

   sqlplus sys/oracle as sysdba

Sqlplus gave us this error message:

   Writing audit records to Windows Event Log failed

Step 3 – Go into the Windows Event Viewer (eventvwr.exe)

Under “Windows Logs”, right click on Application and select “Clear Log”. Do the same for System.

It may also be wise to right click on Application and select Properties. Then, under “Log Size” select the following option under “When maximum log size is reached”: “Overwrite events as needed”. This should prevent the log from maxing out and causing the DB not to start.

In Windows Vista and higher, you can execute the following command to clear the Application log:

   wevtutil cl Application

Step 4 – Login via sqlplus

   sqlplus sys/oracle as sysdba

You should now be able to login with no error messages.

Step 5 - Check the DB listener status

   lsnrctl status

You should now see your listener running.

Step 6 – Start UCM

UCM should now start up.

For a more in-depth answer to this question you can read my full blog post.

please use this

var uri = "ws://localhost:5000/ws";
var socket = new WebSocket(uri);
socket.onclose = function (e){
    console.log(connection closed);
};
window.addEventListener("unload", function () {
    if(socket.readyState == WebSocket.OPEN)
        socket.close();
});

Close browser doesn't trigger websocket close event. You must call socket.close() manually.

It is Vb.Net version:

Public Class Test
Public Property id As Integer
Public Property name As String

  Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click

    Dim x As Date = Now

    Debug.WriteLine("Begin: " & DateDiff(DateInterval.Second, x, Now) & "-" & Now)

    Dim dt As New DataTable
    dt.Columns.Add("id")
    dt.Columns.Add("name")
    dt.Columns.Add("address")
    dt.Columns.Add("createdDate")

    For i As Integer = 0 To 100000
        dt.Rows.Add(i, "name - " & i, "address - " & i, DateAdd(DateInterval.Second, i, Now))
    Next

    Debug.WriteLine("Datatable created: " & DateDiff(DateInterval.Second, x, Now) & "-" & Now)


    Dim items As IList(Of Test) = dt.AsEnumerable().[Select](Function(row) New _
            Test With {
                        .id = row.Field(Of String)("id"),
                        .name = row.Field(Of String)("name"),
                        .address = row.Field(Of String)("address"),
                        .createdDate = row.Field(Of String)("createdDate")
                       }).ToList()

    Debug.WriteLine("List created: " & DateDiff(DateInterval.Second, x, Now) & "-" & Now)

    Debug.WriteLine("Complated")

You might be getting this error because you have updated your password. So on Terminal first make sure you clear your GitHub credentials from the keychain and then push your changes to your repo, terminal will ask for your username and password.

You can return json in PHP this way:

header('Content-Type: application/json');
echo json_encode(array('foo' => 'bar'));
exit;
