From what I remember on Windows the search order for a dll is:

1. Current Directory
2. System folder, C:\windows\system32 or c:\windows\SysWOW64 (for 32-bit process on 64-bit box).
3. Reading from the Path environment variable

In addition I'd check the dependencies of the DLL, the dependency walker provided with Visual Studio can help you out here, it can also be downloaded for free: http://www.dependencywalker.com

The problem could be that the thread calling your code from the hook hasn't been initialized by the runtime so calling runtime methods don't work.

Perhaps you could try doing an Invoke to marshal your code on to the UI thread to call your code that brings the window to the foreground.

If you try to run 32-bit applications on IIS 7 (and/or 64-bit OS machine), you will get the same error. So, from the IIS 7, right click on the applications' application pool and go to "advanced settings" and change "Enable 32-Bit Applications" to "TRUE".

Restart your website and it should work.

Having a space in the file path prevents the Cmd+D from working. I moved my project to a location without a space and I finally got the Chrome debugger to work. Seems like a bug.

Running Android Studio 0.4.0 Solved the problem of importing jar by

Project Structure > Modules > Dependencies > Add Files
Browse to the location of jar file and select it

For those like manual editing Open app/build.gradle

dependencies {
    compile files('src/main/libs/xxx.jar')
}

There is no such font as “Calibri (Body)”. You probably saw this string in Microsoft Word font selection menu, but it’s not a font name (see e.g. the explanation Font: +body (in W07)).

So use just font-family: Calibri or, better, font-family: Calibri, sans-serif. (There is no adequate backup font for Calibri, but the odds are that when Calibri is not available, the browser’s default sans-serif font suits your design better than the browser’s default font, which is most often a serif font.)

You can convert a datetime.date object into a pandas Timestamp like this:

#!/usr/bin/env python3
# coding: utf-8

import pandas as pd
import datetime

# create a datetime data object
d_time = datetime.date(2010, 11, 12)

# create a pandas Timestamp object
t_stamp = pd.to_datetime('2010/11/12')

# cast `datetime_timestamp` as Timestamp object and compare
d_time2t_stamp = pd.to_datetime(d_time)

# print to double check
print(d_time)
print(t_stamp)
print(d_time2t_stamp)

# since the conversion succeds this prints `True`
print(d_time2t_stamp == t_stamp)

You can achieve the desired result by encapsulating the HTML code in a div tag which contains the "required' class followed by the "form-group" class. *however this works only if you have Bootstrap.

<div class="form-group required">
    <div class="required">
        <label>Name:</label>
        <input type="text">
    </div>
  <div>

Comparable is usually preferred. But sometimes a class already implements Comparable, but you want to sort on a different property. Then you're forced to use a Comparator.

Some classes actually provide Comparators for common cases; for instance, Strings are by default case-sensitive when sorted, but there is also a static Comparator called CASE_INSENSITIVE_ORDER.

Some of us prefer languages like Java which force us to declare all the exceptions thrown by methods, instead of making them invisible as in C++ and C#.

When done properly, exceptions are superior to error return codes, if for no other reason than you don't have to propagate failures up the call chain manually.

That being said, low-level API library programming should probably avoid exception handling, and stick to error return codes.

It's been my experience that it's difficult to write clean exception handling code in C++. I end up using new(nothrow) a lot.

You cannot, due to security reasons.

Imagine:

<form name="foo" method="post" enctype="multipart/form-data">
    <input type="file" value="c:/passwords.txt">
</form>
<script>document.foo.submit();</script>

My guess is that $_.Name does not exist.

give width as 0dp to make sure its size is exactly as per its weight this will make sure that even if content of child views get bigger, they'll still be limited to exactly half(according to is weight)

For me it was important to delete the "php.executablePath" path from the VS code settings and leave only the path to PHP in the Path variable.

When I had the Path variable together with php.executablePath, an irritating error still occurred (despite the fact that the path to php was correct).

I agree with Thomas and I would choose the DECIMAL(5,4) solution at least for WPF applications.

Have a look to the MSDN Numeric Format String to know why : http://msdn.microsoft.com/en-us/library/dwhawy9k#PFormatString

The percent ("P") format specifier multiplies a number by 100 and converts it to a string that represents a percentage.

Then you would be able to use this in your XAML code:

DataFormatString="{}{0:P}"

Use the built in promisify library (Node 8+) to make these old callback functions more elegant.

const fs = require('fs');
const util = require('util');

const readFile = util.promisify(fs.readFile);

async function doStuff() {
  try {
    const content = await readFile(filePath, 'utf8');
    console.log(content);
  } catch (e) {
    console.error(e);
  }
}

I once solved this kind of problem by moving all inlines after the class definition and putting the #include for the other classes just before the inlines in the header file. This way one make sure all definitions+inlines are set prior the inlines are parsed.

Doing like this makes it possible to still have a bunch of inlines in both(or multiple) header files. But it's necessary to have include guards.

Like this

// File: A.h
#ifndef __A_H__
#define __A_H__
class B;
class A
{
    int _val;
    B *_b;
public:
    A(int val);
    void SetB(B *b);
    void Print();
};

// Including class B for inline usage here 
#include "B.h"

inline A::A(int val) : _val(val)
{
}

inline void A::SetB(B *b)
{
    _b = b;
    _b->Print();
}

inline void A::Print()
{
    cout<<"Type:A val="<<_val<<endl;
}

#endif /* __A_H__ */

...and doing the same in B.h

It's just JSON? You can stringify() JSON:

var obj = {
    cons: [[String, 'some', 'somemore']],
    func: function(param, param2){
        param2.some = 'bla';
    }
};

var text = JSON.stringify(obj);

And parse back to JSON again with parse():

var myVar = JSON.parse(text);

If you have functions in the object, use this to serialize:

function objToString(obj, ndeep) {
  switch(typeof obj){
    case "string": return '"'+obj+'"';
    case "function": return obj.name || obj.toString();
    case "object":
      var indent = Array(ndeep||1).join('\t'), isArray = Array.isArray(obj);
      return ('{['[+isArray] + Object.keys(obj).map(function(key){
           return '\n\t' + indent +(isArray?'': key + ': ' )+ objToString(obj[key], (ndeep||1)+1);
         }).join(',') + '\n' + indent + '}]'[+isArray]).replace(/[\s\t\n]+(?=(?:[^\'"]*[\'"][^\'"]*[\'"])*[^\'"]*$)/g,'');
    default: return obj.toString();
  }
}

Examples:

Serialize:

var text = objToString(obj); //To Serialize Object

Result:

"{cons:[[String,"some","somemore"]],func:function(param,param2){param2.some='bla';}}"

Deserialize:

Var myObj = eval('('+text+')');//To UnSerialize 

Result:

Object {cons: Array[1], func: function, spoof: function}

For Older browsers, you need to add this line on top of HTML doc

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

RSS is Resident Set Size (physically resident memory - this is currently occupying space in the machine's physical memory), and VSZ is Virtual Memory Size (address space allocated - this has addresses allocated in the process's memory map, but there isn't necessarily any actual memory behind it all right now).

Note that in these days of commonplace virtual machines, physical memory from the machine's view point may not really be actual physical memory.

Take a look at the GeckoFX control.

GeckoFX is an open-source component which makes it easy to embed Mozilla Gecko (Firefox) into any .NET Windows Forms application. Written in clean, fully commented C#, GeckoFX is the perfect replacement for the default Internet Explorer-based WebBrowser control.

I think you're getting confused about what can hold what in JSON.Net.

• A JToken is a generic representation of a JSON value of any kind. It could be a string, object, array, property, etc.
• A JProperty is a single JToken value paired with a name. It can only be added to a JObject, and its value cannot be another JProperty.
• A JObject is a collection of JProperties. It cannot hold any other kind of JToken directly.

In your code, you are attempting to add a JObject (the one containing the "banana" data) to a JProperty ("orange") which already has a value (a JObject containing {"colour":"orange","size":"large"}). As you saw, this will result in an error.

What you really want to do is add a JProperty called "banana" to the JObject which contains the other fruit JProperties. Here is the revised code:

JObject foodJsonObj = JObject.Parse(jsonText);
JObject fruits = foodJsonObj["food"]["fruit"] as JObject;
fruits.Add("banana", JObject.Parse(@"{""colour"":""yellow"",""size"":""medium""}"));

In SSMS: right-click on SQL server icon, Activity Monitor. Open Processes. Find the processed connected. Right-click on the process, Kill.

First of all, it is a bad design, if you need something like that, it is good idea to refactor, e.g. by renaming the method. Java allows calling of overriden method using the "super" keyword, but only one level up in the hierarchy, I am not sure, maybe Scala and some other JVM languages support it for any level.

I'm not using Android Studio, but had same problem. I had to update the latest java jdk and set the JAVA_HOME to that jdk.

There are actually two ways of doing this:

1. st = "Line 1" + vbCrLf + "Line 2"

2. st = "Line 1" + vbNewLine + "Line 2"

These even work for message boxes (and all other places where strings are used).

Yes, using custom tags. Example in Python, making the !join tag join strings in an array:

import yaml

## define custom tag handler
def join(loader, node):
    seq = loader.construct_sequence(node)
    return ''.join([str(i) for i in seq])

## register the tag handler
yaml.add_constructor('!join', join)

## using your sample data
yaml.load("""
paths:
    root: &BASE /path/to/root/
    patha: !join [*BASE, a]
    pathb: !join [*BASE, b]
    pathc: !join [*BASE, c]
""")

Which results in:

{
    'paths': {
        'patha': '/path/to/root/a',
        'pathb': '/path/to/root/b',
        'pathc': '/path/to/root/c',
        'root': '/path/to/root/'
     }
}

The array of arguments to !join can have any number of elements of any data type, as long as they can be converted to string, so !join [*a, "/", *b, "/", *c] does what you would expect.

Linux

If you're using Linux, you can also follow this official wiki pages:

• Configuring SSL certificates on Linux.
• NSS Shared DB And LINUX
• NSS Shared DB Howto

Basically:

• click the lock icon with an X,
• choose Certificate Information
• go to Details tab
• Click on Export... (save as a file)

Now, the following command will add the certificate (where YOUR_FILE is your exported file):

certutil -d sql:$HOME/.pki/nssdb -A -t "P,," -n YOUR_FILE -i YOUR_FILE

To list all your certificates, run the following command:

certutil -d sql:$HOME/.pki/nssdb -L

If it still doesn't work, you could be affected by this bug: Issue 55050: Ubuntu SSL error 8179

P.S. Please also make sure that you have libnss3-tools, before you can use above commands.

If you don't have, please install it by:

sudo apt-get install libnss3-tools # on Ubuntu
sudo yum install nss-tools # on Fedora, Red Hat, etc.

As a bonus, you can use the following handy scripts:

$ cat add_cert.sh
certutil -d sql:$HOME/.pki/nssdb -A -t "P,," -n $1 -i $1
$ cat list_cert.sh
certutil -d sql:$HOME/.pki/nssdb -L # add '-h all' to see all built-in certs
$ cat download_cert.sh
echo QUIT | openssl s_client -connect $1:443 | sed -ne '/BEGIN CERT/,/END CERT/p'

Usage:

add_cert.sh [FILE]
list_cert.sh
download_cert.sh [DOMAIN]

    return o.getClass().getName();
}

At long last, we're excited to announce that we FINALLY implemented copy and paste support for Linux/WSL instances in Windows Console via CTRL + SHIFT + [C|V]!

You can enable/disable this feature in case you find a keyboard collision with a command-line app, but this should start working when you install and run any Win10 builds >= 17643.

Thanks for your patience while we re-engineered Console's internals to allow this feature to work :)

It can be cleaner to add an extension to FileManager for this kind of awkward call, for tidiness if nothing else. Something like:

extension FileManager {
    static var documentDir : URL {
        return FileManager.default.urls(for: .documentDirectory, in: .userDomainMask).first!
    }
}

Of course there are many approaches like synchronous request, promise, but from my experience I think you should use the callback approach. It's natural to asynchronous behavior of Javascript. So, your code snippet can be rewrite a little different:

function foo() {
    var result;

    $.ajax({
        url: '...',
        success: function(response) {
            myCallback(response);
        }
    });

    return result;
}

function myCallback(response) {
    // Does something.
}

It depends on what environment you're running in. In a web browser you simply need to make sure that file1.js is loaded before file2.js:

<script src="file1.js"></script>
<script src="file2.js"></script>

In node.js, the recommended way is to make file1 a module then you can load it with the require function:

require('path/to/file1.js');

It's also possible to use node's module style in HTML using the require.js library.

This works on CentOS:

$ sudo httpd -M |grep rewrite_module

Should output rewrite_module (shared)

If you are making a console window program, you can use system("pause");

Do not delete, use truncate:

Truncate table XXX

The table handler does not remember the last used AUTO_INCREMENT value, but starts counting from the beginning. This is true even for MyISAM and InnoDB, which normally do not reuse sequence values.

Source.

Two things: Change the variables x, y, z as int and call the method as Math.max(Math.max(x,y),z) as it accepts two parameters only.

In Summary, change below:

    String x = keyboard.nextLine();
    String y = keyboard.nextLine();
    String z = keyboard.nextLine();
    int max = Math.max(x,y,z);

to

    int x = keyboard.nextInt();
    int y = keyboard.nextInt();
    int z = keyboard.nextInt();
    int max =  Math.max(Math.max(x,y),z);

From Solaris 11.2 onwards you can indeed do this with the netstat command. Have a look here. The -u switch is what you are looking for.

If you are on a lower version of Solaris then - as others have pointed out - the Solaris way of doing this is some kind of script wrapper around pfiles command. Beware though that pfiles command halts the process for a split second in order to inspect it. For 99.9% of processes this is unimportant. Unfortunately we have a process that will give a core dump if it is hit with a pfiles command so we are a bit cautious about using the command. Your situation may be totally different if you are in the 99.9%, meaning you can safely use the pfiles command.

I think you are putting one too many curly brackets. Try this

 @if($user->status=='waiting')
            <td><a href="#" class="viewPopLink btn btn-default1" role="button" data-id="{!! $user->travel_id !!}" data-toggle="modal" data-target="#myModal">Approve/Reject</a> </td>
            @else
            <td>{!! $user->status !!}</td>
        @endif

You copied using Cells.
If so, no need to PasteSpecial since you are copying data at exactly the same format.
Here's your code with some fixes.

Dim x As Workbook, y As Workbook
Dim ws1 As Worksheet, ws2 As Worksheet

Set x = Workbooks.Open("path to copying book")
Set y = Workbooks.Open("path to pasting book")

Set ws1 = x.Sheets("Sheet you want to copy from")
Set ws2 = y.Sheets("Sheet you want to copy to")

ws1.Cells.Copy ws2.cells
y.Close True
x.Close False

If however you really want to paste special, use a dynamic Range("Address") to copy from.
Like this:

ws1.Range("Address").Copy: ws2.Range("A1").PasteSpecial xlPasteValues
y.Close True
x.Close False

Take note of the : colon after the .Copy which is a Statement Separating character.
Using Object.PasteSpecial requires to be executed in a new line.
Hope this gets you going.

I had this problem running WSL 2

the solution was the command

 $ sudo dockerd

if after that you still have a problem with permission, run the command:

 $ sudo usermod -aG docker your-user

You could get the full path as a string then split it into a list using your operating system's separator character. Then you get the program name, folder name etc by accessing the elements from the end of the list using negative indices.

Like this:

import os
strPath = os.path.realpath(__file__)
print( f"Full Path    :{strPath}" )
nmFolders = strPath.split( os.path.sep )
print( "List of Folders:", nmFolders )
print( f"Program Name :{nmFolders[-1]}" )
print( f"Folder Name  :{nmFolders[-2]}" )
print( f"Folder Parent:{nmFolders[-3]}" )

The output of the above was this:

Full Path    :C:\Users\terry\Documents\apps\environments\dev\app_02\app_02.py
List of Folders: ['C:', 'Users', 'terry', 'Documents', 'apps', 'environments', 'dev', 'app_02', 'app_02.py']
Program Name :app_02.py
Folder Name  :app_02
Folder Parent:dev

Here's another way to do it using map() and lambda functions:

>>> map(lambda d: d['value'], l)

where l is the list. I see this way "sexiest", but I would do it using the list comprehension.

Update: In case that 'value' might be missing as a key use:

>>> map(lambda d: d.get('value', 'default value'), l)

Update: I'm also not a big fan of lambdas, I prefer to name things... this is how I would do it with that in mind:

>>> import operator
>>> get_value = operator.itemgetter('value')
>>> map(get_value, l)

I would even go further and create a sole function that explicitly says what I want to achieve:

>>> import operator, functools
>>> get_value = operator.itemgetter('value')
>>> get_values = functools.partial(map, get_value)
>>> get_values(l)
... [<list of values>]

With Python 3, since map returns an iterator, use list to return a list, e.g. list(map(operator.itemgetter('value'), l)).

Call myTextInputLayout.setError() instead of myEditText.setError().

These container and containment have double functionality on setting errors. Functionality you need is container's one. But you could require minimal version of 23 for that.

Try to browse the service in the browser and in the Https mode, if it is not brow-sable then it proves the reason for this error. Now, to solve this error you need to check :

• https port , check if it is not being used by some other resources (website)
• Check if certificate for https are properly configured or not (check signing authority, self signed certificate, using multiple certificate )
• check WCF service binding and configuration for Https mode

The External Dependencies folder is populated by IntelliSense: the contents of the folder do not affect the build at all (you can in fact disable the folder in the UI).

You need to actually include the header (using a #include directive) to use it. Depending on what that header is, you may also need to add its containing folder to the "Additional Include Directories" property and you may need to add additional libraries and library folders to the linker options; you can set all of these in the project properties (right click the project, select Properties). You should compare the properties with those of the project that does build to determine what you need to add.

Behaviour

Suppose you have two lists:

Id  Value
1   A
2   B
3   C

Id  ChildValue
1   a1
1   a2
1   a3
2   b1
2   b2

When you Join the two lists on the Id field the result will be:

Value ChildValue
A     a1
A     a2
A     a3
B     b1
B     b2

When you GroupJoin the two lists on the Id field the result will be:

Value  ChildValues
A      [a1, a2, a3]
B      [b1, b2]
C      []

So Join produces a flat (tabular) result of parent and child values.
GroupJoin produces a list of entries in the first list, each with a group of joined entries in the second list.

That's why Join is the equivalent of INNER JOIN in SQL: there are no entries for C. While GroupJoin is the equivalent of OUTER JOIN: C is in the result set, but with an empty list of related entries (in an SQL result set there would be a row C - null).

Syntax

So let the two lists be IEnumerable<Parent> and IEnumerable<Child> respectively. (In case of Linq to Entities: IQueryable<T>).

Join syntax would be

from p in Parent
join c in Child on p.Id equals c.Id
select new { p.Value, c.ChildValue }

returning an IEnumerable<X> where X is an anonymous type with two properties, Value and ChildValue. This query syntax uses the Join method under the hood.

GroupJoin syntax would be

from p in Parent
join c in Child on p.Id equals c.Id into g
select new { Parent = p, Children = g }

returning an IEnumerable<Y> where Y is an anonymous type consisting of one property of type Parent and a property of type IEnumerable<Child>. This query syntax uses the GroupJoin method under the hood.

We could just do select g in the latter query, which would select an IEnumerable<IEnumerable<Child>>, say a list of lists. In many cases the select with the parent included is more useful.

Some use cases

1. Producing a flat outer join.

As said, the statement ...

from p in Parent
join c in Child on p.Id equals c.Id into g
select new { Parent = p, Children = g }

... produces a list of parents with child groups. This can be turned into a flat list of parent-child pairs by two small additions:

from p in parents
join c in children on p.Id equals c.Id into g // <= into
from c in g.DefaultIfEmpty()               // <= flattens the groups
select new { Parent = p.Value, Child = c?.ChildValue }

The result is similar to

Value Child
A     a1
A     a2
A     a3
B     b1
B     b2
C     (null)

Note that the range variable c is reused in the above statement. Doing this, any join statement can simply be converted to an outer join by adding the equivalent of into g from c in g.DefaultIfEmpty() to an existing join statement.

This is where query (or comprehensive) syntax shines. Method (or fluent) syntax shows what really happens, but it's hard to write:

parents.GroupJoin(children, p => p.Id, c => c.Id, (p, c) => new { p, c })
       .SelectMany(x => x.c.DefaultIfEmpty(), (x,c) => new { x.p.Value, c?.ChildValue } )

So a flat outer join in LINQ is a GroupJoin, flattened by SelectMany.

2. Preserving order

Suppose the list of parents is a bit longer. Some UI produces a list of selected parents as Id values in a fixed order. Let's use:

var ids = new[] { 3,7,2,4 };

Now the selected parents must be filtered from the parents list in this exact order.

If we do ...

var result = parents.Where(p => ids.Contains(p.Id));

... the order of parents will determine the result. If the parents are ordered by Id, the result will be parents 2, 3, 4, 7. Not good. However, we can also use join to filter the list. And by using ids as first list, the order will be preserved:

from id in ids
join p in parents on id equals p.Id
select p

The result is parents 3, 7, 2, 4.

In my instance of this problem I had to specify box-shadow: none

button:focus {
  outline:none;
  box-shadow: none;
}

The model being shared here is very similar to Ryan Fait's StickyFooter http://ryanfait.com/sticky-footer

Just one div is missing so far in this discussion (the model proposed here by Kenneth Palanganas worked fine for local Win81 design for about 48 hours and then in ie/chrome collapsed for unknown reason). Ryan's "push" div will satisfy some reluctant browsers. Note that px is usual, however, for liquid layout consistency, em may be preferred.

* { border: 0; margin: 0; padding: 0; }
html, body { height: 100%; }
.wrapper { height: auto !important; height: 100%; margin: 0 auto -1em; min-height: 100%; }
.footer, .push { height: 1em; }

<div class="wrapper"><p>Your website content here.</p>
<div class="push"></div>
</div>
<div class="footer"><p>This is a footer</p>
</div>

clear() will be much more efficient. It will simply remove each and every item. Using removeAll(arraylist) will take a lot more work because it will check every item in arraylist to see if it exists in arraylist before removing it.

I deal with the same problem (Jenkins multibranch pipeline) - having only commit information and trying to find a branch name where this commit originally came from. It must work for remote branches, local copies are not available.

This is what I work with:

git rev-parse HEAD | xargs git name-rev

Optionally you can strip the output:

git rev-parse HEAD | xargs git name-rev | cut -d' ' -f2 | sed 's/remotes\/origin\///g'

You can change from the property of every item.

I was working with LAMP and to change the document root folder, I have edited the default file which is there in the /etc/apache2/sites-available folder.

If you want to do the same, just edit as follows:

DocumentRoot /home/username/new_root_folder
    <Directory />
        Options FollowSymLinks
        AllowOverride None
    </Directory>
    <Directory /home/username/new_root_folder>
        Options Indexes FollowSymLinks MultiViews
        AllowOverride None
        Order allow,deny
        allow from all
    </Directory>

After this, if you type "localhost" in the browser, it will load the /home/username/new_root_folder content.

Here you can do it by using HttpRequest or HttpSession. And think your problem is within the JSP.

If you are going to use the inside servlet do following,

Object obj = new Object();
session.setAttribute("object", obj);

or

HttpSession session = request.getSession();
Object obj = new Object();
session.setAttribute("object", obj);

and after setting your attribute by using request or session, use following to access it in the JSP,

<%= request.getAttribute("object")%>

or

<%= session.getAttribute("object")%>

So seems your problem is in the JSP.

If you want use scriptlets it should be as follows,

<%
Object obj = request.getSession().getAttribute("object");
out.print(obj);
%>

Or can use expressions as follows,

<%= session.getAttribute("object")%>

or can use EL as follows, ${object} or ${sessionScope.object}

I wrote this simple function to produce this format: 01:00:03

Seconds are always shown (even if zero). Minutes are shown if greater than zero or if hours or days are required. Hours are shown if greater than zero or if days are required. Days are shown if greater than zero.

function formatSeconds($secs) {
    $result = '';

    $seconds = intval($secs) % 60;
    $minutes = (intval($secs) / 60) % 60;
    $hours = (intval($secs) / 3600) % 24;
    $days = intval(intval($secs) / (3600*24));

    if ($days > 0) {
        $result = str_pad($days, 2, '0', STR_PAD_LEFT) . ':';
    } 

    if(($hours > 0) || ($result!="")) {
        $result .= str_pad($hours, 2, '0', STR_PAD_LEFT) . ':';
    } 

    if (($minutes > 0) || ($result!="")) {
        $result .= str_pad($minutes, 2, '0', STR_PAD_LEFT) . ':';
    } 

    //seconds aways shown
    $result .= str_pad($seconds, 2, '0', STR_PAD_LEFT); 

    return $result;

} //funct

Examples:

echo formatSeconds(15); //15
echo formatSeconds(100); //01:40
echo formatSeconds(10800); //03:00:00 (mins shown even if zero)
echo formatSeconds(10000000); //115:17:46:40 

My solution works with MySQL date time formats and provides a callback function. on complition. Disclaimer: works only with minutes and seconds, as this is what I needed.

jQuery.fn.countDownTimer = function(futureDate, callback){
    if(!futureDate){
        throw 'Invalid date!';
    }

    var currentTs = +new Date();
    var futureDateTs = +new Date(futureDate);

    if(futureDateTs <= currentTs){
        throw 'Invalid date!';
    }


    var diff = Math.round((futureDateTs - currentTs) / 1000);
    var that = this;

    (function countdownLoop(){
        // Get hours/minutes from timestamp
        var m = Math.floor(diff % 3600 / 60);
        var s = Math.floor(diff % 3600 % 60);
        var text = zeroPad(m, 2) + ':' + zeroPad(s, 2);

        $(that).text(text);

        if(diff <= 0){
            typeof callback === 'function' ? callback.call(that) : void(0);
            return;
        }

        diff--;
        setTimeout(countdownLoop, 1000);
    })();

    function zeroPad(num, places) {
      var zero = places - num.toString().length + 1;
      return Array(+(zero > 0 && zero)).join("0") + num;
    }
}

// $('.heading').countDownTimer('2018-04-02 16:00:59', function(){ // on complete})

convert string to datetime object

from datetime import datetime
s = "2016-03-26T09:25:55.000Z"
f = "%Y-%m-%dT%H:%M:%S.%fZ"
out = datetime.strptime(s, f)
print(out)
output:
2016-03-26 09:25:55

:not([class])

Actually, this will select anything that does not have a css class (class="css-selector") applied to it.

I made a jsfiddle demo

    h2 {color:#fff}_x000D_
    :not([class]) {color:red;background-color:blue}_x000D_
    .fake-class {color:green}

    <h2 class="fake-class">fake-class will be green</h2>_x000D_
    <h2 class="">empty class SHOULD be white</h2>_x000D_
    <h2>no class should be red</h2>_x000D_
    <h2 class="fake-clas2s">fake-class2 SHOULD be white</h2>_x000D_
    <h2 class="">empty class2 SHOULD be white</h2>_x000D_
    <h2>no class2 SHOULD be red</h2>

Is this supported? Yes : Caniuse.com (accessed 02 Jan 2020):

• Support: 98.74%
• Partial support: 0.1%
• Total:98.84%

Funny edit, I was Googling for the opposite of :not. CSS negation?

selector[class]  /* the oposite of :not[]*/

Suppose you have a hidden input, named XXX, if you want to assign a value to the following

<script type="text/javascript">

    $(document).ready(function(){
    $('#XXX').val('any value');
    })
</script>

If you use the history,then Router put everything into the location from the history,such as:

this.props.location.pathname;
this.props.location.query;

get it?

std::fill(v.begin(), v.end(), 0);

shlex has a .split() function. It differs from str.split() in that it does not preserve quotes and treats a quoted phrase as a single word:

>>> import shlex
>>> shlex.split("sudo echo 'foo && bar'")
['sudo', 'echo', 'foo && bar']

NB: it works well for Unix-like command line strings. It doesn't work for natural-language processing.

Using datetime example

>>> from datetime import datetime
>>> then = datetime(2012, 3, 5, 23, 8, 15)        # Random date in the past
>>> now  = datetime.now()                         # Now
>>> duration = now - then                         # For build-in functions
>>> duration_in_s = duration.total_seconds()      # Total number of seconds between dates

Duration in years

>>> years = divmod(duration_in_s, 31536000)[0]    # Seconds in a year=365*24*60*60 = 31536000.

Duration in days

>>> days  = duration.days                         # Build-in datetime function
>>> days  = divmod(duration_in_s, 86400)[0]       # Seconds in a day = 86400

Duration in hours

>>> hours = divmod(duration_in_s, 3600)[0]        # Seconds in an hour = 3600

Duration in minutes

>>> minutes = divmod(duration_in_s, 60)[0]        # Seconds in a minute = 60

Duration in seconds

[!] See warning about using duration in seconds in the bottom of this post

>>> seconds = duration.seconds                    # Build-in datetime function
>>> seconds = duration_in_s

Duration in microseconds

[!] See warning about using duration in microseconds in the bottom of this post

>>> microseconds = duration.microseconds          # Build-in datetime function

Total duration between the two dates

>>> days    = divmod(duration_in_s, 86400)        # Get days (without [0]!)
>>> hours   = divmod(days[1], 3600)               # Use remainder of days to calc hours
>>> minutes = divmod(hours[1], 60)                # Use remainder of hours to calc minutes
>>> seconds = divmod(minutes[1], 1)               # Use remainder of minutes to calc seconds
>>> print("Time between dates: %d days, %d hours, %d minutes and %d seconds" % (days[0], hours[0], minutes[0], seconds[0]))

or simply:

>>> print(now - then)

Edit 2019 Since this answer has gained traction, I'll add a function, which might simplify the usage for some

from datetime import datetime

def getDuration(then, now = datetime.now(), interval = "default"):

    # Returns a duration as specified by variable interval
    # Functions, except totalDuration, returns [quotient, remainder]

    duration = now - then # For build-in functions
    duration_in_s = duration.total_seconds() 
    
    def years():
      return divmod(duration_in_s, 31536000) # Seconds in a year=31536000.

    def days(seconds = None):
      return divmod(seconds if seconds != None else duration_in_s, 86400) # Seconds in a day = 86400

    def hours(seconds = None):
      return divmod(seconds if seconds != None else duration_in_s, 3600) # Seconds in an hour = 3600

    def minutes(seconds = None):
      return divmod(seconds if seconds != None else duration_in_s, 60) # Seconds in a minute = 60

    def seconds(seconds = None):
      if seconds != None:
        return divmod(seconds, 1)   
      return duration_in_s

    def totalDuration():
        y = years()
        d = days(y[1]) # Use remainder to calculate next variable
        h = hours(d[1])
        m = minutes(h[1])
        s = seconds(m[1])

        return "Time between dates: {} years, {} days, {} hours, {} minutes and {} seconds".format(int(y[0]), int(d[0]), int(h[0]), int(m[0]), int(s[0]))

    return {
        'years': int(years()[0]),
        'days': int(days()[0]),
        'hours': int(hours()[0]),
        'minutes': int(minutes()[0]),
        'seconds': int(seconds()),
        'default': totalDuration()
    }[interval]

# Example usage
then = datetime(2012, 3, 5, 23, 8, 15)
now = datetime.now()

print(getDuration(then)) # E.g. Time between dates: 7 years, 208 days, 21 hours, 19 minutes and 15 seconds
print(getDuration(then, now, 'years'))      # Prints duration in years
print(getDuration(then, now, 'days'))       #                    days
print(getDuration(then, now, 'hours'))      #                    hours
print(getDuration(then, now, 'minutes'))    #                    minutes
print(getDuration(then, now, 'seconds'))    #                    seconds

Warning: Caveat about built-in .seconds and .microseconds
datetime.seconds and datetime.microseconds are capped to [0,86400) and [0,10^6) respectively.

They should be used carefully if timedelta is bigger than the max returned value.

Examples:

end is 1h and 200µs after start:

>>> start = datetime(2020,12,31,22,0,0,500)
>>> end = datetime(2020,12,31,23,0,0,700)
>>> delta = end - start
>>> delta.microseconds
RESULT: 200
EXPECTED: 3600000200

end is 1d and 1h after start:

>>> start = datetime(2020,12,30,22,0,0)
>>> end = datetime(2020,12,31,23,0,0)
>>> delta = end - start
>>> delta.seconds
RESULT: 3600
EXPECTED: 90000

I know this thread is a year old now but having experienced the same problem I managed to solve the problem by setting a target server for my project.

i.e. right-click on your project and select 'Properties' -> 'Targeted Runtimes' and select the server you going to run your web app on (Tomcat 6 or 7).

If none of the above solutions work for any reason, like my case, try this:

  <script type="text/javascript">
    $(function()
    {
      $('[name="my_checkbox"]').change(function()
      {
        if ($(this).is(':checked')) {
           // Do something...
           alert('You can rock now...');
        };
      });
    });
  </script>

In your gemfile add:

gem 'execjs'
gem 'therubyracer', :platforms => :ruby

For more details: ExecJS and could not find a JavaScript runtime

The other answers perform a fixed (width, height) resize. If you wanted to resize to a specific size while maintaining aspect ratio, use this

def ResizeWithAspectRatio(image, width=None, height=None, inter=cv2.INTER_AREA):
    dim = None
    (h, w) = image.shape[:2]

    if width is None and height is None:
        return image
    if width is None:
        r = height / float(h)
        dim = (int(w * r), height)
    else:
        r = width / float(w)
        dim = (width, int(h * r))

    return cv2.resize(image, dim, interpolation=inter)

Example

image = cv2.imread('img.png')
resize = ResizeWithAspectRatio(image, width=1280) # Resize by width OR
# resize = ResizeWithAspectRatio(image, height=1280) # Resize by height 

cv2.imshow('resize', resize)
cv2.waitKey()

I add the changes directly to my virtualhost instead the global config of nginx, like this:

   server {
     client_max_body_size 100M;
     ...
   }

And then I change the params in php.ini, like the comments above:

   max_input_time = 24000
   max_execution_time = 24000
   upload_max_filesize = 12000M
   post_max_size = 24000M
   memory_limit = 12000M

and what you can not forget is to restart nginx and php-fpm, in centos 7 is like this:

  systemctl restart nginx
  systemctl restart php-fpm

    public static bool IsPalindrome(string str)
    {
        int i = 0;
        int a = 0;

        char[] chr = str.ToCharArray();
        foreach (char cr in chr)
        {
            Array.Reverse(chr);
            if (chr[i] == cr)
            {
                if (a == str.Length)
                {
                    return true;
                }
                a++;
                i++;
            }
            else
            {
                return false;
            }
        }
        return true;
    }

CentOS is Linux, so as in just about all other Unix/Linux systems, you have the find command. To search for files within the current directory:

find -name "filename"

You can also have wildcards inside the quotes, and not just a strict filename. You can also explicitly specify a directory to start searching from as the first argument to find:

find / -name "filename"

will look for "filename" or all the files that match the regex expression in between the quotes, starting from the root directory. You can also use single quotes instead of double quotes, but in most cases you don't need either one, so the above commands will work without any quotes as well. Also, for example, if you're searching for java files and you know they are somewhere in your /home/username, do:

find /home/username -name *.java

There are many more options to the find command and you should do a:

man find

to learn more about it.

One more thing: if you start searching from / and are not root or are not sudo running the command, you might get warnings that you don't have permission to read certain directories. To ignore/remove those, do:

find / -name 'filename' 2>/dev/null

That just redirects the stderr to /dev/null.

Try:

array[i] = Convert.ToDouble(Console.Readline());

You might also want to use double.TryParse() to make sure that the user didn't enter bogus text and handle that somehow.

Make sure you use the latest version of JDK/JRE.

In my case, I had put JCE into JRE folder, but it didn't help. It happened because I was running my project from the IDE directly (using JDK).

Then I updated my JDK and JRE to the latest version (1.8.0_211) and the problem had gone.

More details: https://bugs.java.com/bugdatabase/view_bug.do?bug_id=JDK-8170157

If based on click here it is:

ng-click="orderReverse = orderReverse ? false : true"

The syntax for accessing a dict given a key is number_map[int(x)]. number_map(int(x)) would actually be a function call but since number_map is not a callable, an exception is raised.

Like the other answers have said, instance methods operate on an object and has access to its instance variables, while a class method operates on a class as a whole and has no access to a particular instance's variables (unless you pass the instance in as a parameter).

A good example of an class method is a counter-type method, which returns the total number of instances of a class. Class methods start with a +, while instance ones start with an -. For example:

static int numberOfPeople = 0;

@interface MNPerson : NSObject {
     int age;  //instance variable
}

+ (int)population; //class method. Returns how many people have been made.
- (id)init; //instance. Constructs object, increments numberOfPeople by one.
- (int)age; //instance. returns the person age
@end

@implementation MNPerson
- (id)init{
    if (self = [super init]){
          numberOfPeople++;
          age = 0;
    }    
    return self;
}

+ (int)population{ 
     return numberOfPeople;
}

- (int)age{
     return age;
}

@end

main.m:

MNPerson *micmoo = [[MNPerson alloc] init];
MNPerson *jon = [[MNPerson alloc] init];
NSLog(@"Age: %d",[micmoo age]);
NSLog(@"%Number Of people: %d",[MNPerson population]);

Output: Age: 0 Number Of people: 2

Another example is if you have a method that you want the user to be able to call, sometimes its good to make that a class method. For example, if you have a class called MathFunctions, you can do this:

+ (int)square:(int)num{ 
      return num * num;
}

So then the user would call:

[MathFunctions square:34];

without ever having to instantiate the class!

You can also use class functions for returning autoreleased objects, like NSArray's

+ (NSArray *)arrayWithObject:(id)object

That takes an object, puts it in an array, and returns an autoreleased version of the array that doesn't have to be memory managed, great for temperorary arrays and what not.

I hope you now understand when and/or why you should use class methods!!

Trying to access an undefined variable will throw you a ReferenceError.

A solution to this is to use typeof:

if (typeof window === "undefined") {
  console.log("Oops, `window` is not defined")
}

or a try catch:

try { window } catch (err) {
  console.log("Oops, `window` is not defined")
}

While typeof window is probably the cleanest of the two, the try catch can still be useful in some cases.

On the same note, if your server supports both http and https you can connect using:

var socket = io.connect('//localhost');

to auto detect the browser scheme and connect using http/https accordingly. when in https, the transport will be secured by default, as connecting using

var socket = io.connect('https://localhost');

will use secure web sockets - wss:// (the {secure: true} is redundant).

for more information on how to serve both http and https easily using the same node server check out this answer.

getElementById is defined by DOM Level 1 HTML to return null in the case no element is matched.

!==null is the most explicit form of the check, and probably the best, but there is no non-null falsy value that getElementById can return - you can only get null or an always-truthy Element object. So there's no practical difference here between !==null, !=null or the looser if (document.getElementById('xx')).

React is not passing you the kind of events you might think. Rather, it is passing synthetic events.

In a brief test, event.keyCode == 0 is always true. What you want is event.charCode

Daemon threads are killed ungracefully so any finalizer instructions are not executed. A possible solution is to check is main thread is alive instead of infinite loop.

E.g. for Python 3:

while threading.main_thread().isAlive():
    do.you.subthread.thing()
gracefully.close.the.thread()

See Check if the Main Thread is still alive from another thread.

this worked for me:

var blobToBase64 = function(blob, callback) {
    var reader = new FileReader();
    reader.onload = function() {
        var dataUrl = reader.result;
        var base64 = dataUrl.split(',')[1];
        callback(base64);
    };
    reader.readAsDataURL(blob);
};

This simple example illustrates it:

MR_COUNT = 0        # constant defined on main Object class
module Foo
  MR_COUNT = 0
  ::MR_COUNT = 1    # set global count to 1
  MR_COUNT = 2      # set local count to 2
end

puts MR_COUNT       # this is the global constant: 1
puts Foo::MR_COUNT  # this is the local constant: 2

What's the first part of your Subversion repository URL?

• If your URL looks like: http://subversion/repos/, then you're probably going over Port 80.
• If your URL looks like: https://subversion/repos/, then you're probably going over Port 443.
• If your URL looks like: svn://subversion/, then you're probably going over Port 3690.
• If your URL looks like: svn+ssh://subversion/repos/, then you're probably going over Port 22.
• If your URL contains a port number like: http://subversion/repos:8080, then you're using that port.

I can't guarantee the first four since it's possible to reconfigure everything to use different ports, of if you go through a proxy of some sort.

If you're using a VPN, you may have to configure your VPN client to reroute these to their correct ports. A lot of places don't configure their correctly VPNs to do this type of proxying. It's either because they have some sort of anal-retentive IT person who's being overly security conscious, or because they simply don't know any better. Even worse, they'll give you a client where this stuff can't be reconfigured.

The only way around that is to log into a local machine over the VPN, and then do everything from that system.

From the post above, I think the best way is

1. Have a fixed div with width: 100%
2. Inside the div, make a new static div with margin-left: auto and margin-right: auto, or for table make it align="center".
3. Tadaaaah, you have centered your fixed div now

Hope this will help.

Seems to be a common Windows problem. This fixed it for me:

Nodejs cannot find installed module on Windows?

"Add an environment variable called NODE_PATH and set it to %USERPROFILE%\Application Data\npm\node_modules (Windows XP), %AppData%\npm\node_modules (Windows 7), or wherever npm ends up installing the modules on your Windows flavor. To be done with it once and for all, add this as a System variable in the Advanced tab of the System Properties dialog (run control.exe sysdm.cpl,System,3)."

Note that you can't actually use another environment variable within the value of NODE_PATH. That is, don't just copy and paste that string above, but set it to an actual resolved path like C:\Users\MYNAME\AppData\Roaming\npm\node_modules

If you're looking to get promise in resource call, you should use

Regions.query().$q.then(function(){ .... })

Update : the promise syntax is changed in current versions which reads

Regions.query().$promise.then(function(){ ..... })

Those who have downvoted don't know what it was and who first added this promise to resource object. I used this feature in late 2012 - yes 2012.

No. There isn't..

But, for development there is such a link on the jQuery code site.

You need to find the position of the first /, and then calculate the portion you want:

string url = "www.example.com/aaa/bbb.jpg";
int Idx = url.IndexOf("/");
string yourValue = url.Substring(Idx + 1, url.Length - Idx - 4);

You may use line-height on div1 as below:

<div id="div1" style="line-height:0px;">
    <div></div><div></div><div></div><br/><div></div><div></div><div></div>
</div>

Sun's java 1.4 has the following arguments to control memory size:

-Xmsn Specify the initial size, in bytes, of the memory allocation pool. This value must be a multiple of 1024 greater than 1MB. Append the letter k or K to indicate kilobytes, or m or M to indicate megabytes. The default value is 2MB. Examples:

           -Xms6291456
           -Xms6144k
           -Xms6m

-Xmxn Specify the maximum size, in bytes, of the memory allocation pool. This value must a multiple of 1024 greater than 2MB. Append the letter k or K to indicate kilobytes, or m or M to indicate megabytes. The default value is 64MB. Examples:

           -Xmx83886080
           -Xmx81920k
           -Xmx80m

Java 5 and 6 have some more. See http://java.sun.com/javase/technologies/hotspot/vmoptions.jsp

Simplest way is to Check the Output - Build tab: It would display the location of war file.
It will have something like:

Installing D:\Project\target\Tool.war to C:\Users\myname.m2\repository\com\tool\1.0\Tool-1.0.war

On Mac press Ctrl+\ to quit a python process attached to a terminal.

You can use it by using the StackTrace and then you can get reflective types from that.

StackTrace stackTrace = new StackTrace();           // get call stack
StackFrame[] stackFrames = stackTrace.GetFrames();  // get method calls (frames)

StackFrame callingFrame = stackFrames[1];
MethodInfo method = callingFrame.GetMethod();
Console.Write(method.Name);
Console.Write(method.DeclaringType.Name);

It appears that as of Java 7, David Santamaria's answer doesn't work reliably any more. It looks like you can still reliably use a Socket to test the connection, however.

private static boolean available(int port) {
    System.out.println("--------------Testing port " + port);
    Socket s = null;
    try {
        s = new Socket("localhost", port);

        // If the code makes it this far without an exception it means
        // something is using the port and has responded.
        System.out.println("--------------Port " + port + " is not available");
        return false;
    } catch (IOException e) {
        System.out.println("--------------Port " + port + " is available");
        return true;
    } finally {
        if( s != null){
            try {
                s.close();
            } catch (IOException e) {
                throw new RuntimeException("You should handle this error." , e);
            }
        }
    }
}

What you can do is select everything into a new instance of Course, and afterwards convert them to a List.

var qry = from a in obj.tbCourses
                     select new Course() {
                         Course.Property = a.Property
                         ...
                     };

qry.toList<Course>();

These are automatic variables, like $null, $true, $false etc.

about_Automatic_Variables, see https://technet.microsoft.com/en-us/library/hh847768.aspx?f=255&MSPPError=-2147217396

$NULL
$null is an automatic variable that contains a NULL or empty value. You can use this variable to represent an absent or undefined value in commands and scripts.

Windows PowerShell treats $null as an object with a value, that is, as an explicit placeholder, so you can use $null to represent an empty value in a series of values.

For example, when $null is included in a collection, it is counted as one of the objects.

C:\PS> $a = ".dir", $null, ".pdf"
C:\PS> $a.count
3

If you pipe the $null variable to the ForEach-Object cmdlet, it generates a value for $null, just as it does for the other objects.

PS C:\ps-test> ".dir", $null, ".pdf" | Foreach {"Hello"}
Hello
Hello
Hello

As a result, you cannot use $null to mean "no parameter value." A parameter value of $null overrides the default parameter value.

However, because Windows PowerShell treats the $null variable as a placeholder, you can use it scripts like the following one, which would not work if $null were ignored.

$calendar = @($null, $null, “Meeting”, $null, $null, “Team Lunch”, $null)
$days = Sunday","Monday","Tuesday","Wednesday","Thursday","Friday","Saturday"
$currentDay = 0

foreach($day in $calendar)
{
    if($day –ne $null)
    {
        "Appointment on $($days[$currentDay]): $day"
    }

    $currentDay++
}

output:

Appointment on Tuesday: Meeting
Appointment on Friday: Team lunch

Pretty old question but check this for a more clustered way of checking conditions:

private bool IsColumn(string col, params string[] names) => names.Any(n => n == col);

usage:

private void CheckColumn()
{
     if(!IsColumn(ColName, "Column A", "Column B", "Column C"))
    {
     //not A B C column
    }

}

Also works in ubuntu with Ctrl+E

When dealing with large streams, like a file sized over 4GB - you don't want to load the file into memory (as a Byte[]) because not only is it very slow, but also may cause a crash as even in 64-bit processes a Byte[] cannot exceed 2GB (or 4GB with gcAllowVeryLargeObjects).

Fortunately there's a neat helper in .NET called ToBase64Transform which processes a stream in chunks. For some reason Microsoft put it in System.Security.Cryptography and it implements ICryptoTransform (for use with CryptoStream), but disregard that ("a rose by any other name...") just because you aren't performing any cryprographic tasks.

You use it with CryptoStream like so:

using System.Security.Cryptography;
using System.IO;

//

using( FileStream   inputFile    = new FileStream( @"C:\VeryLargeFile.bin", FileMode.Open, FileAccess.Read, FileShare.None, bufferSize: 1024 * 1024, useAsync: true ) ) // When using `useAsync: true` you get better performance with buffers much larger than the default 4096 bytes.
using( CryptoStream base64Stream = new CryptoStream( inputFile, new ToBase64Transform(), CryptoStreamMode.Read ) )
using( FileStream   outputFile   = new FileStream( @"C:\VeryLargeBase64File.txt", FileMode.CreateNew, FileAccess.Write, FileShare.None, bufferSize: 1024 * 1024, useAsync: true ) )
{
    await base64Stream.CopyToAsync( outputFile ).ConfigureAwait(false);
}

One possible solution that I use is to use python3. It seems to solve many utf issues.

Sorry for the late answer, but it may help people in the future.

For example,

#!/usr/bin/env python3
import json
# your code follows

You can test-drive this code exactly as is using the public GitHub API (don't go over the request limit):

public class App {

    public static void main(String[] args) throws IOException {

        CloseableHttpClient client = HttpClients.custom().build();

        // (1) Use the new Builder API (from v4.3)
        HttpUriRequest request = RequestBuilder.get()
                .setUri("https://api.github.com")
                // (2) Use the included enum
                .setHeader(HttpHeaders.CONTENT_TYPE, "application/json")
                // (3) Or your own
                .setHeader("Your own very special header", "value")
                .build();

        CloseableHttpResponse response = client.execute(request);

        // (4) How to read all headers with Java8
        List<Header> httpHeaders = Arrays.asList(response.getAllHeaders());
        httpHeaders.stream().forEach(System.out::println);

        // close client and response
    }
}

The FragmentManger's function add and replace can be described as these 1. add means it will add the fragment in the fragment back stack and it will show at given frame you are providing like

getFragmentManager.beginTransaction.add(R.id.contentframe,Fragment1.newInstance(),null)

2.replace means that you are replacing the fragment with another fragment at the given frame

getFragmentManager.beginTransaction.replace(R.id.contentframe,Fragment1.newInstance(),null)

The Main utility between the two is that when you are back stacking the replace will refresh the fragment but add will not refresh previous fragment.

Trident provides the ::-ms-check pseudo-element for checkbox and radio button controls. For example:

<input type="checkbox">
<input type="radio">

::-ms-check {
    color: red;
    background: black;
    padding: 1em;
}

This displays as follows in IE10 on Windows 8:

sort ip_addresses | uniq -c

This will print the count first, but other than that it should be exactly what you want.

Not exactly an answer to the question because the question already has great answers. This is a side info. Enabling general_log really put a dent on MySQL performance. I left general_log =1 accidentally on a production server and spent hours finding out why performance was not comparable to a similar setup on other servers. Then I found this which explains the impact of enabling general log. http://www.fromdual.com/general_query_log_vs_mysql_performance.

Gist of the story, don't put general_log=1 in the .cnf file. Instead use set global general_log =1 for a brief duration just to log enough to find out what you are trying to find out and then turn it off.

I am glad you were able to get this done in this manner, but you can (and I did) use the GParted tool for my Windows XP host by following the helpful entry by Eric. To re-iterate/expand on his solution (don't be afraid of the # steps, I'm trying to help newbies here, so there are necessarily more detailed instructions!):

1. change the size of the virtual hard disk via the VBoxManage modifyhd command, which is well-documented here and in the VirtualBox documentation.

2. download the GParted-live (http://sourceforge.net/projects/gparted/files/latest/download?source=dlp) or search the internet for GParted-live ISO. The important part is to get the live (.iso) verison, which is in the form of a bootable .ISO (CD) image.

3. Mount this new .ISO to the CD virtual drive in the host machine's Storage settings

4. If necessary/desired, change the boot order in the System settings for the host machine, to boot from CD before Hard Disk (alternatively, you can press F12 when it's booting up, and select the device)

5. start your VM; if you changed the boot order, it will boot to the GParted-live ISO; otherwise press F12 to do this.

6. do not be afraid or get too confused/wrapped up in the initial options you are presented; I selected all the defaults (booting to GParted default, default key mapping, language (assuming English - sorry for my non-English friends!), display, etc.). Read it, but just press enter at each prompt. With a Windows VM you should be fine with all the defaults, and if you're not, you're not going to break anything, and the instructions are pretty good about what to do if the defaults don't work.

7. it will boot to a GUI environment and start the GParted utility. Highlight the c: drive (assuming that's the drive you want to increase the size on) and select resize/move.

8. change to the new size you want in MB (they abbreviate MiB) - just add the new amount available (represented in the bottom number - MiB following) to the middle number. E.g: I changed mine from like 4000 MiB (e.g., 4GB - my initial size) to 15000 MiB (15 GB) because I'd added 10 GB to my virtual disk. Then click OK.

9. Click Apply. Once it's done you'll have to reboot - for whatever reason my mouse did not work on the desktop icons on the GUI (I could not click exit) so I just closed the VM window and selected reboot. I did not even have to unmount the ISO, it apparently did it automatically.

10. Let Windows go through the disk check - remember, you just changed the size outside of Windows, so it has no record of this. This will presumably allow it to update itself with the new info. Once it completes and you log in, you'll likely be told that Windows needs to reboot to use your 'new device' (at least in XP it did for me). Just reboot and you are done!

In Java, as you may know, exceptions can be categorized into two: One that needs the throws clause or must be handled if you don't specify one and another one that doesn't. Now, see the following figure:

In Java, you can throw anything that extends the Throwable class. However, you don't need to specify a throws clause for all classes. Specifically, classes that are either an Error or RuntimeException or any of the subclasses of these two. In your case Exception is not a subclass of an Error or RuntimeException. So, it is a checked exception and must be specified in the throws clause, if you don't handle that particular exception. That is why you needed the throws clause.

From Java Tutorial:

An exception is an event, which occurs during the execution of a program, that disrupts the normal flow of the program's instructions.

Now, as you know exceptions are classified into two: checked and unchecked. Why these classification?

Checked Exception: They are used to represent problems that can be recovered during the execution of the program. They usually are not the programmer's fault. For example, a file specified by user is not readable, or no network connection available, etc., In all these cases, our program doesn't need to exit, instead it can take actions like alerting the user, or go into a fallback mechanism(like offline working when network not available), etc.

Unchecked Exceptions: They again can be divided into two: Errors and RuntimeExceptions. One reason for them to be unchecked is that they are numerous in number, and required to handle all of them will clutter our program and reduce its clarity. The other reason is:

• Runtime Exceptions: They usually happen due to a fault by the programmer. For example, if an ArithmeticException of division by zero occurs or an ArrayIndexOutOfBoundsException occurs, it is because we are not careful enough in our coding. They happen usually because some errors in our program logic. So, they must be cleared before our program enters into production mode. They are unchecked in the sense that, our program must fail when it occurs, so that we programmers can resolve it at the time of development and testing itself.

• Errors: Errors are situations from which usually the program cannot recover. For example, if a StackOverflowError occurs, our program cannot do much, such as increase the size of program's function calling stack. Or if an OutOfMemoryError occurs, we cannot do much to increase the amount of RAM available to our program. In such cases, it is better to exit the program. That is why they are made unchecked.

For detailed information see:

• Unchecked Exceptions — The Controversy
• The Catch or Specify Requirement

Yes, but in what file is pyth_test's definition declared in? Is it also located before it's called?

Edit:

To put it into perspective, create a file called test.py with the following contents:

def pyth_test (x1, x2):
    print x1 + x2

pyth_test(1,2)

Now run the following command:

python test.py

You should see the output you desire. Now if you are in an interactive session, it should go like this:

>>> def pyth_test (x1, x2):
...     print x1 + x2
... 
>>> pyth_test(1,2)
3
>>> 

I hope this explains how the declaration works.

To give you an idea of how the layout works, we'll create a few files. Create a new empty folder to keep things clean with the following:

myfunction.py

def pyth_test (x1, x2):
    print x1 + x2 

program.py

#!/usr/bin/python

# Our function is pulled in here
from myfunction import pyth_test

pyth_test(1,2)

Now if you run:

python program.py

It will print out 3. Now to explain what went wrong, let's modify our program this way:

# Python: Huh? where's pyth_test?
# You say it's down there, but I haven't gotten there yet!
pyth_test(1,2)

# Our function is pulled in here
from myfunction import pyth_test

Now let's see what happens:

$ python program.py 
Traceback (most recent call last):
  File "program.py", line 3, in <module>
    pyth_test(1,2)
NameError: name 'pyth_test' is not defined

As noted, python cannot find the module for the reasons outlined above. For that reason, you should keep your declarations at top.

Now then, if we run the interactive python session:

>>> from myfunction import pyth_test
>>> pyth_test(1,2)
3

The same process applies. Now, package importing isn't all that simple, so I recommend you look into how modules work with Python. I hope this helps and good luck with your learnings!

I ended up going with a shell script that you should only really have to run once when you first checkout a project

#!/usr/bin/env bash

mkdir -p webroot/js
mkdir -p webroot/css
mkdir -p webroot/css-min
mkdir -p webroot/img
mkdir -p webroot/font

npm i
bower i

# boostrap
pushd components/bootstrap
npm i
make bootstrap
popd
cp components/bootstrap/bootstrap/css/*.min.css webroot/css-min/
cp components/bootstrap/bootstrap/js/bootstrap.js src/js/deps/
cp components/bootstrap/bootstrap/img/* webroot/img/

# fontawesome
cp components/font-awesome/css/*.min.css webroot/css-min/
cp components/font-awesome/font/* webroot/font/

I realized that several answers have been provided but no real fix yet.

The reason, as mentioned above, is a "End of line" missing at the end of the CSV file.

While the real Fix should come from Microsoft, the walk around is to open the CSV file with a Text-editor and add a line at the end of the file (aka press return key). I use ATOM software as a text/code editor but virtually all basic text editor would do.

In the meanwhile, please report the bug to Microsoft.

Question: It seems to me that it is a office 2016 problem. Does anyone have the issue on a PC?

UPDATE: for rxjs > v5.5

As mentioned in some of the comments and other answers, by default the HttpClient deserializes the content of a response into an object. Some of its methods allow passing a generic type argument in order to duck-type the result. Thats why there is no json() method anymore.

import {throwError} from 'rxjs';
import {catchError, map} from 'rxjs/operators';

export interface Order {
  // Properties
}

interface ResponseOrders {
  results: Order[];
}

@Injectable()
export class FooService {
 ctor(private http: HttpClient){}

 fetch(startIndex: number, limit: number): Observable<Order[]> {
    let params = new HttpParams();
    params = params.set('startIndex',startIndex.toString()).set('limit',limit.toString());
    // base URL should not have ? in it at the en
    return this.http.get<ResponseOrders >(this.baseUrl,{
       params
    }).pipe(
       map(res => res.results || []),
       catchError(error => _throwError(error.message || error))
    );
} 

Notice that you could easily transform the returned Observable to a Promise by simply invoking toPromise().

ORIGINAL ANSWER:

In your case, you can

Assumming that your backend returns something like:

{results: [{},{}]}

in JSON format, where every {} is a serialized object, you would need the following:

// Somewhere in your src folder

export interface Order {
  // Properties
}

import { HttpClient, HttpParams } from '@angular/common/http';
import { Observable } from 'rxjs/Observable';
import 'rxjs/add/operator/catch';
import 'rxjs/add/operator/map';

import { Order } from 'somewhere_in_src';    

@Injectable()
export class FooService {
 ctor(private http: HttpClient){}

 fetch(startIndex: number, limit: number): Observable<Order[]> {
    let params = new HttpParams();
    params = params.set('startIndex',startIndex.toString()).set('limit',limit.toString());
    // base URL should not have ? in it at the en
    return this.http.get(this.baseUrl,{
       params
    })
    .map(res => res.results as Order[] || []); 
   // in case that the property results in the res POJO doesnt exist (res.results returns null) then return empty array ([])
  }
} 

I removed the catch section, as this could be archived through a HTTP interceptor. Check the docs. As example:

https://gist.github.com/jotatoledo/765c7f6d8a755613cafca97e83313b90

And to consume you just need to call it like:

// In some component for example
this.fooService.fetch(...).subscribe(data => ...); // data is Order[]

SciPy's imresize() method was another resize method, but it will be removed starting with SciPy v 1.3.0 . SciPy refers to PIL image resize method: Image.resize(size, resample=0)

size – The requested size in pixels, as a 2-tuple: (width, height).
resample – An optional resampling filter. This can be one of PIL.Image.NEAREST (use nearest neighbour), PIL.Image.BILINEAR (linear interpolation), PIL.Image.BICUBIC (cubic spline interpolation), or PIL.Image.LANCZOS (a high-quality downsampling filter). If omitted, or if the image has mode “1” or “P”, it is set PIL.Image.NEAREST.

Link here: https://pillow.readthedocs.io/en/3.1.x/reference/Image.html#PIL.Image.Image.resize

Declare them outside the subroutines, like this:

Public wbA as Workbook
Public wbB as Workbook
Sub MySubRoutine()
    Set wbA = Workbooks.Open("C:\file.xlsx")
    Set wbB = Workbooks.Open("C:\file2.xlsx")
    OtherSubRoutine
End Sub
Sub OtherSubRoutine()
    MsgBox wbA.Name, vbInformation
End Sub

Alternately, you can pass variables between subroutines:

Sub MySubRoutine()
Dim wbA as Workbook
Dim wbB as Workbook
    Set wbA = Workbooks.Open("C:\file.xlsx")
    Set wbB = Workbooks.Open("C:\file2.xlsx")
    OtherSubRoutine wbA, wbB
End Sub
Sub OtherSubRoutine(wb1 as Workbook, wb2 as Workbook)
    MsgBox wb1.Name, vbInformation
    MsgBox wb2.Name, vbInformation
End Sub

Or use Functions to return values:

Sub MySubroutine()
    Dim i as Long
    i = MyFunction()
    MsgBox i
End Sub
Function MyFunction()
    'Lots of code that does something
    Dim x As Integer, y as Double
    For x = 1 to 1000
        'Lots of code that does something
    Next
    MyFunction = y
End Function

In the second method, within the scope of OtherSubRoutine you refer to them by their parameter names wb1 and wb2. Passed variables do not need to use the same names, just the same variable types. This allows you some freedom, for example you have a loop over several workbooks, and you can send each workbook to a subroutine to perform some action on that Workbook, without making all (or any) of the variables public in scope.

A Note About User Forms

Personally I would recommend keeping Option Explicit in all of your modules and forms (this prevents you from instantiating variables with typos in their names, like lCoutn when you meant lCount etc., among other reasons).

If you're using Option Explicit (which you should), then you should qualify module-scoped variables for style and to avoid ambiguity, and you must qualify user-form Public scoped variables, as these are not "public" in the same sense. For instance, i is undefined, though it's Public in the scope of UserForm1:

You can refer to it as UserForm1.i to avoid the compile error, or since forms are New-able, you can create a variable object to contain reference to your form, and refer to it that way:

NB: In the above screenshots x is declared Public x as Long in another standard code module, and will not raise the compilation error. It may be preferable to refer to this as Module2.x to avoid ambiguity and possible shadowing in case you re-use variable names...

The benefit is that the output of previous function is used. You do not need to repeat where the data source comes from, for example.

1. Use require function when you need to load any class, function, or dependency.

2. Use include function when you want to load template-styled file

If you are still confused, just use require_once for all time.

If you mean delete every instance of all models, I would use

ActiveRecord::Base.connection.tables.map(&:classify)
  .map{|name| name.constantize if Object.const_defined?(name)}
  .compact.each(&:delete_all)

In force layouts simply setting the 'height' and 'width' attributes will not work to re-center/move the plot into the svg container. However, there's a very simple answer that works for Force Layouts found here. In summary:

Use same (any) eventing you like.

window.on('resize', resize);

Then assuming you have svg & force variables:

var svg = /* D3 Code */;
var force = /* D3 Code */;    

function resize(e){
    // get width/height with container selector (body also works)
    // or use other method of calculating desired values
    var width = $('#myselector').width(); 
    var height = $('#myselector').height(); 

    // set attrs and 'resume' force 
    svg.attr('width', width);
    svg.attr('height', height);
    force.size([width, height]).resume();
}

In this way, you don't re-render the graph entirely, we set the attributes and d3 re-calculates things as necessary. This at least works when you use a point of gravity. I'm not sure if that's a prerequisite for this solution. Can anyone confirm or deny ?

see my answer here:

How can I get the current date and time in UTC or GMT in Java?

I've fully tested it by changing the timezones on the emulator

Once I had written a program that handle the short (-h), long (--help) and non-option arguments in batch file. This techniques includes:

• non-option arguments followed by a option arguments.

• shift operator for those options that have no argument like '--help'.

• two time shift operator for those options that require an argument.

• loop through a label for processing all command line arguments.

• Exit script and stop processing for those options that no need to require further action like '--help'.

• Wrote help functions for user guidiness

From matplotlib 3.1 onwards you can use .legend_elements(). An example is shown in Automated legend creation. The advantage is that a single scatter call can be used.

In this case:

import numpy as np
import pandas as pd
import matplotlib.pyplot as plt

df = pd.DataFrame(np.random.normal(10,1,30).reshape(10,3), 
                  index = pd.date_range('2010-01-01', freq = 'M', periods = 10), 
                  columns = ('one', 'two', 'three'))
df['key1'] = (4,4,4,6,6,6,8,8,8,8)


fig, ax = plt.subplots()
sc = ax.scatter(df['one'], df['two'], marker = 'o', c = df['key1'], alpha = 0.8)
ax.legend(*sc.legend_elements())
plt.show()

In case the keys were not directly given as numbers, it would look as

import numpy as np
import pandas as pd
import matplotlib.pyplot as plt

df = pd.DataFrame(np.random.normal(10,1,30).reshape(10,3), 
                  index = pd.date_range('2010-01-01', freq = 'M', periods = 10), 
                  columns = ('one', 'two', 'three'))
df['key1'] = list("AAABBBCCCC")

labels, index = np.unique(df["key1"], return_inverse=True)

fig, ax = plt.subplots()
sc = ax.scatter(df['one'], df['two'], marker = 'o', c = index, alpha = 0.8)
ax.legend(sc.legend_elements()[0], labels)
plt.show()

Way to instantly get first value:

$neededObject = array_reduce(
    $arrayOfObjects,
    function ($result, $item) use ($searchedValue) {
        return $item->id == $searchedValue ? $item : $result;
    }
);

If you have no other links, then there is no use for navbar-header....

HTML:

<nav class="navbar navbar-inverse navbar-static-top">
    <div class="container">
     <a class="navbar-brand text-center center-block" href="#">Navbar Brand</a>
  .....
</nav>

CSS:

.navbar-brand {
  float: none;
}

However, if you do want other links here's a very effective approach that allows that: https://stackoverflow.com/a/34149840/3123861

If you are running ASP.Net, check out the Bundling and Minification module available in ASP.Net 4.5.

http://www.asp.net/mvc/tutorials/mvc-4/bundling-and-minification

You can declare a "bundle" that points to your javascript file. Every time your file changes, it will generate a new querystring suffix... but will only do so when the file changes. This makes it super simple to deploy updates, because you don't even have to think about updating your tags with new version numbers.

It can also bundle multiple .js files together into one file, and minify them, all in one step. Ditto for css.

The following is a way to achieve a fixed header table, I don't know if it will be enough for your purpose. Changes are:

1. use "bScrollCollapse" instead of "sScrollXInner"
2. don't use fieldset to wrap table
3. add a "div.box" css class

It seems fully working on my local machine, but it's not fully working using Fiddle. It seems that Fiddle adds a css file (normalize.css) that in some way broke the plugin css (quite sure I can make fully working also in Fiddle adding some css clear rules, but not have time to investigate further now)

My working code snippet is below. Hope this can help.

In example 3 you don't modify the array. In all other examples you modify either the contents or the internal array pointer. This is important when it comes to PHP arrays because of the semantics of the assignment operator.

The assignment operator for the arrays in PHP works more like a lazy clone. Assigning one variable to another that contains an array will clone the array, unlike most languages. However, the actual cloning will not be done unless it is needed. This means that the clone will take place only when either of the variables is modified (copy-on-write).

Here is an example:

$a = array(1,2,3);
$b = $a;  // This is lazy cloning of $a. For the time
          // being $a and $b point to the same internal
          // data structure.

$a[] = 3; // Here $a changes, which triggers the actual
          // cloning. From now on, $a and $b are two
          // different data structures. The same would
          // happen if there were a change in $b.

Coming back to your test cases, you can easily imagine that foreach creates some kind of iterator with a reference to the array. This reference works exactly like the variable $b in my example. However, the iterator along with the reference live only during the loop and then, they are both discarded. Now you can see that, in all cases but 3, the array is modified during the loop, while this extra reference is alive. This triggers a clone, and that explains what's going on here!

Here is an excellent article for another side effect of this copy-on-write behaviour: The PHP Ternary Operator: Fast or not?

I faced the same problem. Initially I deleted the .bash_profile but this is not the right way. After installing anaconda it is showing the instructions clearly for this problem. Please check the image for solution provided by Anaconda

MySQL recommends using indexes for a variety of reasons including elimination of rows between conditions: http://dev.mysql.com/doc/refman/5.0/en/mysql-indexes.html

This makes your datetime column an excellent candidate for an index if you are going to be using it in conditions frequently in queries. If your only condition is BETWEEN NOW() AND DATE_ADD(NOW(), INTERVAL 30 DAY) and you have no other index in the condition, MySQL will have to do a full table scan on every query. I'm not sure how many rows are generated in 30 days, but as long as it's less than about 1/3 of the total rows it will be more efficient to use an index on the column.

Your question about creating an efficient database is very broad. I'd say to just make sure that it's normalized and all appropriate columns are indexed (i.e. ones used in joins and where clauses).

There is a new free-to-use webtool, where you can view any xml schema:

Online XML Schema Viewer

www.xml-tools.net

It's written completely in JavaScript, so it's running in most modern browsers.

it's pretty painless to pop a couple methods in a file that will handle asynchronous data in a serialized order and give a more conventional flavour to your code. For example:

module.exports = function () {
  var self = this;

  this.each = async (items, fn) => {
    if (items && items.length) {
      await Promise.all(
        items.map(async (item) => {
          await fn(item);
        }));
    }
  };

  this.reduce = async (items, fn, initialValue) => {
    await self.each(
      items, async (item) => {
        initialValue = await fn(initialValue, item);
      });
    return initialValue;
  };
};

now, assuming that's saved at './myAsync.js' you can do something similar to the below in an adjacent file:

...
/* your server setup here */
...
var MyAsync = require('./myAsync');
var Cat = require('./models/Cat');
var Doje = require('./models/Doje');
var example = async () => {
  var myAsync = new MyAsync();
  var doje = await Doje.findOne({ name: 'Doje', noises: [] }).save();
  var cleanParams = [];

  // FOR EACH EXAMPLE
  await myAsync.each(['bork', 'concern', 'heck'], 
    async (elem) => {
      if (elem !== 'heck') {
        await doje.update({ $push: { 'noises': elem }});
      }
    });

  var cat = await Cat.findOne({ name: 'Nyan' });

  // REDUCE EXAMPLE
  var friendsOfNyanCat = await myAsync.reduce(cat.friends,
    async (catArray, friendId) => {
      var friend = await Friend.findById(friendId);
      if (friend.name !== 'Long cat') {
        catArray.push(friend.name);
      }
    }, []);
  // Assuming Long Cat was a friend of Nyan Cat...
  assert(friendsOfNyanCat.length === (cat.friends.length - 1));
}

Swift 5
let desiredIndex: Int = 7 let substring = str[String.Index(encodedOffset: desiredIndex)...]
This substring variable will give you the result.
Simply here Int is converted to Index and then you can split the strings. Unless you will get errors.

>>> a = 255556
>>> a == 255556
True
>>> a is 255556
False

I think that should answer it ;-)

The reason is that some often-used objects, such as the booleans True and False, all 1-letter strings and short numbers are allocated once by the interpreter, and each variable containing that object refers to it. Other numbers and larger strings are allocated on demand. The 255556 for instance is allocated three times, every time a different object is created. And therefore, according to is, they are not the same.

Use (V3 version):

(Get-Content c:\temp\test.txt).replace('[MYID]', 'MyValue') | Set-Content c:\temp\test.txt

Or for V2:

(Get-Content c:\temp\test.txt) -replace '\[MYID\]', 'MyValue' | Set-Content c:\temp\test.txt

/usr/local/ssl/openssl.cnf

is soft link of

/etc/ssl/openssl.cnf

You can see that using long list (ls -l) on the /usr/local/ssl/ directory where you will find

lrwxrwxrwx 1 root root 20 Mar 1 05:15 openssl.cnf -> /etc/ssl/openssl.cnf

Since you want the trailing string from the input, you can use %n (number of characters consumed thus far) to get the position at which the trailing string starts. This avoids memory copies and buffer sizing issues, but comes at the cost that you may need to do them explicitly if you wanted a copy.

const char *input = "19  cool kid";
int age;
int nameStart = 0;
sscanf(input, "%d %n", &age, &nameStart);
printf("%s is %d years old\n", input + nameStart, age);

outputs:

cool kid is 19 years old

In my case the issue was that Virtual directory was not created.

1. Right click on web project file and go to properties
2. Navigate to Web
3. Scroll down to Project Url
4. Click Create Virtual Directory button to create virtual directory

Great Answer by Jon.

I'm lazy though and I hate typing, so I created a simple cut and paste example for all the other people who are like me. Enjoy!

import java.util.ArrayList;
import java.util.List;

public class Main {

    public static void main(String[] args) {

        List<String> animals = new ArrayList<>();

        animals.add("Lion");
        animals.add("Tiger");
        animals.add("Cat");
        animals.add("Dog");

        System.out.println(animals); // [Lion, Tiger, Cat, Dog]

        // add() -> push(): Add items to the end of an array
        animals.add("Elephant");
        System.out.println(animals);  // [Lion, Tiger, Cat, Dog, Elephant]

        // remove() -> pop(): Remove an item from the end of an array
        animals.remove(animals.size() - 1);
        System.out.println(animals); // [Lion, Tiger, Cat, Dog]

        // add(0,"xyz") -> unshift(): Add items to the beginning of an array
        animals.add(0, "Penguin");
        System.out.println(animals); // [Penguin, Lion, Tiger, Cat, Dog]

        // remove(0) -> shift(): Remove an item from the beginning of an array
        animals.remove(0);
        System.out.println(animals); // [Lion, Tiger, Cat, Dog]

    }

}

This is largely a shameless clone of my answer to the Java question of the same topic. It turns out that JewelCLI is Scala-friendly in that it doesn't require JavaBean style methods to get automatic argument naming.

JewelCLI is a Scala-friendly Java library for command-line parsing that yields clean code. It uses Proxied Interfaces Configured with Annotations to dynamically build a type-safe API for your command-line parameters.

An example parameter interface Person.scala:

import uk.co.flamingpenguin.jewel.cli.Option

trait Person {
  @Option def name: String
  @Option def times: Int
}

An example usage of the parameter interface Hello.scala:

import uk.co.flamingpenguin.jewel.cli.CliFactory.parseArguments
import uk.co.flamingpenguin.jewel.cli.ArgumentValidationException

object Hello {
  def main(args: Array[String]) {
    try {
      val person = parseArguments(classOf[Person], args:_*)
      for (i <- 1 to (person times))
        println("Hello " + (person name))
    } catch {
      case e: ArgumentValidationException => println(e getMessage)
    }
  }
}

Save copies of the files above to a single directory and download the JewelCLI 0.6 JAR to that directory as well.

Compile and run the example in Bash on Linux/Mac OS X/etc.:

scalac -cp jewelcli-0.6.jar:. Person.scala Hello.scala
scala -cp jewelcli-0.6.jar:. Hello --name="John Doe" --times=3

Compile and run the example in the Windows Command Prompt:

scalac -cp jewelcli-0.6.jar;. Person.scala Hello.scala
scala -cp jewelcli-0.6.jar;. Hello --name="John Doe" --times=3

Running the example should yield the following output:

Hello John Doe
Hello John Doe
Hello John Doe

I tried with cygwin & gnuwin, and didn't worked for me, I guess because the makefile used mainly specific linux code.

What it worked was use Ubuntu Bash for Windows 10. This is a Marvel if you come from MAC as it is my case:

1. To install the Ubuntu Bash: https://itsfoss.com/install-bash-on-windows/
2. Once in the console, to install make simply type "make" and it gives the instructions to download it.

Extras:

1. Useful enable copy / paste on bash: Copy Paste in Bash on Ubuntu on Windows
2. In my case the make called Maven, so I have to install it as well: https://askubuntu.com/questions/722993/unable-to-locate-package-maven
3. To access windows filesystem C: drive, for example: "cd /mnt/c/"

Hope it helps

I'm using VerboseRunnable class from jcabi-log, which swallows all exceptions and logs them. Very convenient, for example:

import com.jcabi.log.VerboseRunnable;
scheduler.scheduleWithFixedDelay(
  new VerboseRunnable(
    Runnable() {
      public void run() { 
        // the code, which may throw
      }
    },
    true // it means that all exceptions will be swallowed and logged
  ),
  1, 1, TimeUnit.MILLISECONDS
);

Since this post is tagged Windows, I thought I would work out a solution for Windows. I wanted to automate the process, and I made a bat file. I resisted making a console.exe in C#.

I wanted to add any files or folders which are not added in my repository when I begin the commit process.

The problem with many of the answers is they will list unversioned files which should be ignored as per my ignore list in TortoiseSVN.

Here is my hook setting and batch file which does that

Tortoise Hook Script:

"start_commit_hook".
(where I checkout) working copy path = C:\Projects
command line: C:\windows\system32\cmd.exe /c C:\Tools\SVN\svnadd.bat
(X) Wait for the script to finish
(X) (Optional) Hide script while running
(X) Always execute the script

svnadd.bat

@echo off

rem Iterates each line result from the command which lists files/folders
rem     not added to source control while respecting the ignore list.
FOR /F "delims==" %%G IN ('svn status ^| findstr "^?"') DO call :DoSVNAdd "%%G"
goto end

:DoSVNAdd
set addPath=%1
rem Remove line prefix formatting from svn status command output as well as
rem    quotes from the G call (as required for long folder names). Then
rem    place quotes back around the path for the SVN add call.
set addPath="%addPath:~9,-1%"
svn add %addPath%

:end

This function avoids you having to list out every variable in your dataset just to order a few of them.

def order(frame,var):
    if type(var) is str:
        var = [var] #let the command take a string or list
    varlist =[w for w in frame.columns if w not in var]
    frame = frame[var+varlist]
    return frame 

It takes two arguments, the first is the dataset, the second are the columns in the data set that you want to bring to the front.

So in my case I have a data set called Frame with variables A1, A2, B1, B2, Total and Date. If I want to bring Total to the front then all I have to do is:

frame = order(frame,['Total'])

If I want to bring Total and Date to the front then I do:

frame = order(frame,['Total','Date'])

EDIT:

Another useful way to use this is, if you have an unfamiliar table and you're looking with variables with a particular term in them, like VAR1, VAR2,... you may execute something like:

frame = order(frame,[v for v in frame.columns if "VAR" in v])

List<Employee> employees = new List<Employee>()
{
    new Employee{Id =1,Name="AAAAA"}
    , new Employee{Id =2,Name="BBBBB"}
    , new Employee{Id =3,Name="AAAAA"}
    , new Employee{Id =4,Name="CCCCC"}
    , new Employee{Id =5,Name="AAAAA"}
};

List<Employee> duplicateEmployees = employees.Except(employees.GroupBy(i => i.Name)
                                             .Select(ss => ss.FirstOrDefault()))
                                            .ToList();

In order to have this result:

{"aoColumnDefs":[{"aTargets":[0],"aDataSort":[0,1]},{"aTargets":[1],"aDataSort":[1,0]},{"aTargets":[2],"aDataSort":[2,3,4]}]}

that holds the same data as:

  {
    "aoColumnDefs": [
     { "aDataSort": [ 0, 1 ], "aTargets": [ 0 ] },
     { "aDataSort": [ 1, 0 ], "aTargets": [ 1 ] },
     { "aDataSort": [ 2, 3, 4 ], "aTargets": [ 2 ] }
   ]
  }

you could use this code:

    JSONObject jo = new JSONObject();
    Collection<JSONObject> items = new ArrayList<JSONObject>();

    JSONObject item1 = new JSONObject();
    item1.put("aDataSort", new JSONArray(0, 1));
    item1.put("aTargets", new JSONArray(0));
    items.add(item1);
    JSONObject item2 = new JSONObject();
    item2.put("aDataSort", new JSONArray(1, 0));
    item2.put("aTargets", new JSONArray(1));
    items.add(item2);
    JSONObject item3 = new JSONObject();
    item3.put("aDataSort", new JSONArray(2, 3, 4));
    item3.put("aTargets", new JSONArray(2));
    items.add(item3);

    jo.put("aoColumnDefs", new JSONArray(items));

    System.out.println(jo.toString());

the thing that work for me was to set /etc/hosts to point the hostname to the ip and not to the loopback interface and than restart my application.

cat /etc/hosts

127.0.0.1      localhost.localdomain localhost
192.168.0.1    myservername

This is my configuration:

-Dcom.sun.management.jmxremote.port=1617 
-Dcom.sun.management.jmxremote.ssl=false 
-Dcom.sun.management.jmxremote.authenticate=false

GitHub is a great tool in-all for making repositories. However, it does not do good with private repositories.

You're forced to pay for private repositories unless you get some sort of plan. I have a couple of projects so far, and if GitHub doesn't do what I want I just go to Bitbucket. It's a bit harder to work with than GitHub, however it's unlimited free repositories.

Check your folder structure where you are executing the command, you should run the command 'ng serve' where there should be a angular.json file in the structure.

angular.json file will be generated by default when we run the command

npm install -g '@angular/cli' ng new Project_name then cd project_folder then, run ng serve. it worked for me

Either use a real fully qualified domain name (like dev.yourdomain.com) that pointing to 127.0.0.1 or try editing the proper hosts file (usually /etc/hosts in *nix environments).

I don't how this works, but it worked.

As explained here http://www.postgresonline.com/journal/categories/journal/archives/339-OGR-foreign-data-wrapper-on-Windows-first-taste.html

With ogr_fdw module, its possible to open the excel sheet as foreign table in pgsql and query it directly like any other regular tables in pgsql. This is useful for reading data from the same regularly updated table

To do this, the table header in your spreadsheet must be clean, the current ogr_fdw driver can't deal with wide-width character or new lines etc. with these characters, you will probably not be able to reference the column in pgsql due to encoding issue. (Major reason I can't use this wonderful extension.)

The ogr_fdw pre-build binaries for windows are located here http://winnie.postgis.net/download/windows/pg96/buildbot/extras/ change the version number in link to download corresponding builds. extract the file to pgsql folder to overwrite the same name sub-folders. restart pgsql. Before the test drive, the module needs to be installed by executing:

CREATE EXTENSION ogr_fdw;

Usage in brief:

1. use ogr_fdw_info.exe to prob the excel file for sheet name list

   ogr_fdw_info -s "C:/excel.xlsx"
   

2. use "ogr_fdw_info.exe -l" to prob a individual sheet and generate a table definition code.

   ogr_fdw_info -s "C:/excel.xlsx" -l "sheetname"
   

Execute the generated definition code in pgsql, a foreign table is created and mapped to your excel file. it can be queried like regular tables.

This is especially useful, if you have many small files with the same table structure. Just change the path and name in definition, and update the definition will be enough.

This plugin supports both XLSX and XLS file. According to the document it also possible to write data back into the spreadsheet file, but all the fancy formatting in your excel will be lost, the file is recreated on write.

If the excel file is huge. This will not work. which is another reason I didn't use this extension. It load data in one time. But this extension also support ODBC interface, it should be possible to use windows' ODBC excel file driver to create a ODBC source for the excel file and use ogr_fdw or any other pgsql's ODBC foreign data wrapper to query this intermediate ODBC source. This should be fairly stable.

The downside is that you can't change file location or name easily within pgsql like in the previous approach.

A friendly reminder. The permission issue applies to this fdw extensions. since its loaded into pgsql service. pgsql must have access privileged to the excel files.

First check if the table/column(id/name) combination exists in dbo.syscolumns (an internal SQL Server table that contains field definitions), and if not issue the appropriate ALTER TABLE query to add it. For example:

IF NOT EXISTS ( SELECT  *
            FROM    syscolumns
            WHERE   id = OBJECT_ID('Client')
                    AND name = 'Name' ) 
ALTER TABLE Client
ADD Name VARCHAR(64) NULL

Though there are other correct answers here (such as using classes), from an academic point of view it is of course possible to have multiple divs with the same ID, and it is possible to select them with jQuery.

When you use

jQuery("#elemid") 

it selects only the first element with the given ID.

However, when you select by attribute (e.g. id in your case), it returns all matching elements, like so:

jQuery("[id=elemid]") 

This of course works for selection on any attribute, and you could further refine your selection by specifying the tag in question (e.g. div in your case)

jQuery("div[id=elemid]") 

You only need this link jspdf.min.js

It has everything in it.

<script src="https://cdnjs.cloudflare.com/ajax/libs/jspdf/1.3.2/jspdf.min.js"></script>

The order is always implied in the structure of the regular expression. To accomplish what you want, you'll have to match the input string multiple times against different expressions.

What you want to do is not possible with a single regexp.

The best solution I could find was listening to the scroll event on the window and set the scrollTop to the previous scrollTop if the child div was visible.

prevScrollPos = 0
$(window).scroll (ev) ->
    if $('#mydiv').is(':visible')
        document.body.scrollTop = prevScrollPos
    else
        prevScrollPos = document.body.scrollTop

There is a flicker in the background of the child div if you fire a lot of scroll events, so this could be tweaked, but it is hardly noticed and it was sufficient for my use case.

select 1 from table

will return a column of 1's for every row in the table. You could use it with a where statement to check whether you have an entry for a given key, as in:

if exists(select 1 from table where some_column = 'some_value')

What your friend was probably saying is instead of making bulk selects with select * from table, you should specify the columns that you need precisely, for two reasons:

1) performance & you might retrieve more data than you actually need.

2) the query's user may rely on the order of columns. If your table gets updated, the client will receive columns in a different order than expected.

Starting from Apache HTTPComponents 4.3.x HttpClientBuilder class sets the proxy defaults from System properties http.proxyHost and http.proxyPort or else you can override them using setProxy method.

If you are just opened a new java project then create a new folder src/ in the man project location.

Then cut and paste all your package in that folder.

Then Right click on src directory and select option Mark Directory As > Sources Root.

You need a regular expression like "\\s+", which means: split whenever at least one whitespace is encountered. The full Java code is:

try {
    String[] splitArray = input.split("\\s+");
} catch (PatternSyntaxException ex) {
    // 
}

man your container is 40% of the width of the parent element

but when you use position:fixed, the width is based on viewport(document) width...

thinking about, i realized your parent element have 10% padding(left and right), it means your element have 80% of the total page width. so your fixed element must have 40% based on 80% of total width

so you just need to change your #fixed class to

#fixed{ 
    position:fixed;
    width: calc(80% * 0.4);
    height:10px;
    background-color:#333;
}

if you use sass, postcss or another css compiler, you can use variables to avoid breaking the layout when you change the padding value of parent element.

My reason was having same library with different snapshot versions in WEB-INF/lib:

some-lib-3.14.0.143-SNAPSHOT.jar
some-lib-3.14.0.143-20200708.101204-1.jar

To fix the issue remove redundant copy.

I think most of the important stuff has been said, but I just thought I'd add one thing: If you compile as Any CPU and run on an x64 platform, then you won't be able to load 32-bit DLL files, because your application wasn't started in WoW64, but those DLL files need to run there.

If you compile as x86, then the x64 system will run your application in WoW64, and you'll be able to load 32-bit DLL files.

So I think you should choose "Any CPU" if your dependencies can run in either environment, but choose x86 if you have 32-bit dependencies. This article from Microsoft explains this a bit:

/CLRIMAGETYPE (Specify Type of CLR Image)

Incidentally, this other Microsoft documentation agrees that x86 is usually a more portable choice:

Choosing x86 is generally the safest configuration for an app package since it will run on nearly every device. On some devices, an app package with the x86 configuration won't run, such as the Xbox or some IoT Core devices. However, for a PC, an x86 package is the safest choice and has the largest reach for device deployment. A substantial portion of Windows 10 devices continue to run the x86 version of Windows.

It's often mentioned that to list a complete list of attributes you should use dir(). Note however that contrary to popular belief dir() does not bring out all attributes. For example you might notice that __name__ might be missing from a class's dir() listing even though you can access it from the class itself. From the doc on dir() (Python 2, Python 3):

Because dir() is supplied primarily as a convenience for use at an interactive prompt, it tries to supply an interesting set of names more than it tries to supply a rigorously or consistently defined set of names, and its detailed behavior may change across releases. For example, metaclass attributes are not in the result list when the argument is a class.

A function like the following tends to be more complete, although there's no guarantee of completeness since the list returned by dir() can be affected by many factors including implementing the __dir__() method, or customizing __getattr__() or __getattribute__() on the class or one of its parents. See provided links for more details.

def dirmore(instance):
    visible = dir(instance)
    visible += [a for a in set(dir(type)).difference(visible)
                if hasattr(instance, a)]
    return sorted(visible)

Sometimes you do get focus but no cursor in a text field. In this case you would do this:

document.getElementById(frmObj.id).select();

This is a tool to open Java class file binaries, view their internal structure, modify portions of it if required and save the class file back. It also generates readable reports similar to the javap utility. Easy to use Java Swing GUI. The user interface tries to display as much detail as possible and tries to present a structure as close as the actual Java class file structure. At the same time ease of use and class file consistency while doing modifications is also stressed. For example, when a method is deleted, the associated constant pool entry will also be deleted if it is no longer referenced. In built verifier checks changes before saving the file. This tool has been used by people learning Java class file internals. This tool has also been used to do quick modifications in class files when the source code is not available." this is a quote from the website.

http://classeditor.sourceforge.net/

Text files in Windows don't have a format. There's an unofficial convention that if the file starts with the BOM codepoint in UTF-8 format that it's UTF-8, but that convention isn't universally supported. That would be the 3 byte sequence "\xef\xbf\xbe", i.e. ￾ in the Latin-1 character set.

From the context, the conflict was caused by the version of the package.
Let's take a look the manual about rpm:

--force
    Same as using --replacepkgs, --replacefiles, and --oldpackage.

--oldpackage
    Allow an upgrade to replace a newer package with an older one.

So, you can execute the command rpm -Uvh info-4.13a-2.rpm --force to solve your issue.

For Python Run This Command

The up-to-date answer (as of PHP 5.4 or newer) for generating 404 pages is to use http_response_code:

<?php
http_response_code(404);
include('my_404.php'); // provide your own HTML for the error page
die();

die() is not strictly necessary, but it makes sure that you don't continue the normal execution.

This is a correct answer:

<a class="btn" ng-click="remove($index)">Delete</a>
$scope.remove=function($index){ 
  $scope.bdays.splice($index,1);     
}

In @charlietfl's answer. I think it's wrong since you pass $index as paramter but you use the wish instead in controller. Correct me if I'm wrong :)

UPDATE tobeupdated
INNER JOIN original ON (tobeupdated.value = original.value)
SET tobeupdated.id = original.id

That should do it, and really its doing exactly what yours is. However, I prefer 'JOIN' syntax for joins rather than multiple 'WHERE' conditions, I think its easier to read

As for running slow, how large are the tables? You should have indexes on tobeupdated.value and original.value

EDIT: we can also simplify the query

UPDATE tobeupdated
INNER JOIN original USING (value)
SET tobeupdated.id = original.id

USING is shorthand when both tables of a join have an identical named key such as id. ie an equi-join - http://en.wikipedia.org/wiki/Join_(SQL)#Equi-join

To determine if the array is sparse, it may help to get a proportion of nan values

np.isnan(ndarr).sum() / ndarr.size

If that proportion exceeds a threshold, then use a sparse array, e.g. - https://sparse.pydata.org/en/latest/

I presume from your static array example that you want a rectangular array, and not a jagged one. You can use the following:

int *ary = new int[sizeX * sizeY];

Then you can access elements as:

ary[y*sizeX + x]

Don't forget to use delete[] on ary.

A simple (no checks for overflow or for validity of arguments) implementation for the repeated-squaring algorithm for computing the power:

/** Compute a**p, assume result fits in a 32-bit signed integer */ 
int pow(int a, int p)
{
    int res = 1;
    int i1 = 31 - Integer.numberOfLeadingZeros(p); // highest bit index
    for (int i = i1; i >= 0; --i) {
        res *= res;
        if ((p & (1<<i)) > 0)
            res *= a;
    }
    return res;
}

The time complexity is logarithmic to exponent p (i.e. linear to the number of bits required to represent p).

Use escape characters: "full\\path\\here", "\\" and "\\\\"

You can use this in your MySQL WHERE clause to return records that were created within the last 7 days/week:

created >= DATE_SUB(CURDATE(),INTERVAL 7 day)

Also use NOW() in the subtraction to give hh:mm:ss resolution. So to return records created exactly (to the second) within the last 24hrs, you could do:

created >= DATE_SUB(NOW(),INTERVAL 1 day)

You can use Array.delete_at(0) method which will delete first element.

 x = [2,3,4,11,0]
 x.delete_at(0) unless x.empty? # [3,4,11,0]

Previous versions of Angular (pre 1.0 RC) allowed you to use this interchangeably with the $scope method, but this is no longer the case. Inside of methods defined on the scope this and $scope are interchangeable (angular sets this to $scope), but not otherwise inside your controller constructor.

To bring back this behaviour (does anyone know why was it changed?) you can add:

return angular.extend($scope, this);

at the end of your controller function (provided that $scope was injected to this controller function).

This has a nice effect of having access to parent scope via controller object that you can get in child with require: '^myParentDirective'

Why not use globalize? This is only one of the issues that you can run in to when you don't use the english language:

Globalize.parseFloat('0,04'); // 0.04

Some links on stackoverflow to look into:

• Jquery Globalization
• Globalization in JQuery is not working

You have some errors in your code:

1. Use myArray[i].push( 0 ); to add a new column. Your code (myArray[i][j].push(0);) would work in a 3-dimensional array as it tries to add another element to an array at position [i][j].
2. You only expand (col-d)-many columns in all rows, even in those, which haven't been initialized yet and thus have no entries so far.

One correct, although kind of verbose version, would be the following:

var r = 3; //start from rows 3

var rows = 8;
var cols = 7;

// expand to have the correct amount or rows
for( var i=r; i<rows; i++ ) {
  myArray.push( [] );
}

// expand all rows to have the correct amount of cols
for (var i = 0; i < rows; i++)
{
    for (var j =  myArray[i].length; j < cols; j++)
    {
        myArray[i].push(0);
    }
}

You can download gems from https://rubygems.org/gems/ or build you local gem via bundle and rack.

• bundle gem yourGemName
• rake install

Take care of installing dependencies before installing actual gems.

• gem install --local /pathToFolder/xxx-2.6.1.gem

Note: If using fluentd td-agent and ruby on same machine. Please make sure to use td-agent's td-agent-gem command. td-agent has own Ruby.

Everything you need to know about underscore template is here. Only 3 things to keep in mind:

1. <% %> - to execute some code
2. <%= %> - to print some value in template
3. <%- %> - to print some values HTML escaped

That's all about it.

Simple example:

var tpl = _.template("<h1>Some text: <%= foo %></h1>");

then tpl({foo: "blahblah"}) would be rendered to the string <h1>Some text: blahblah</h1>
