in rails 2.3.X,just type following command to start rails server on linux

script/server

and for more help read "README" file which is already created in rails project folder

You can use LINQ for this

var list = new List<int>();
var sum = list.Sum();

and for a List of strings like Roy Dictus said you have to convert

list.Sum(str => Convert.ToInt32(str));

On my side, i got this problem when i added a new project (Library)

How i solved it

Right click the new added Library go to Properties then Application, under Application change the Target Framework to the framework of all projects.

The problem is that you have project using different target frameworks.

I guess these days you would do:

import subprocess

subprocess.run(["pwd"], cwd="sub-dir")

Nothing from above worked for me. The problem for me was that I had wrong source in my Java Build Path for android-support-v7-appcompat. When you go to Project> Build Path> Configure Build Path>. Under the Source tab make sure you have android-support-v7-appcompat/gen , android-support-v7-appcompat/libs and android-support-v7-appcompat/src and nothing else. Click OK and it should work.

If you already have your line of text in a variable $LINE, then you should be able to say

for L in $LINE; do
   echo $L;
done

If you want the basic answer to have the files on the left-hand side, just go on "View" then "Tool Buttons", you will then be able to choose "project".

There is a jQuery plugin that can deal with this very well

http://www.jqui.net/jquery-projects/jquery-mutate-official/

here is a demo of it with different scenarios as to when the height change, if you resize the red bordered div.

In my case, I needed to install a plugin to an offline build server that's running a Windows Server (version won't matter here). I already installed Jenkins on my laptop to test out changes in advance and it is running on localhost:8080 as a windows service.

So if you are willing to take the time to setup Jenkins on a machine with Internet connection and carry these changes to the offline server Jenkins (it works, confirmed by me!), these are steps you could follow:

• Jenkins on my laptop: Open up Jenkins, http://localhost:8080
• Navigator: Manage Jenkins | Download plugin without install option
• Windows Explorer: Copy the downloaded plugin file that is located at "c:\program files (x86)\Jenkins\plugins" folder (i.e. role-strategy.jpi)
• Paste it into a shared folder in the offline server
• Stop the Jenkins Service (Offline Server Jenkins) through Component Services, Jenkins Service
• Copy the plugin file (i.e. role-strategy.jpi) into "c:\program files (x86)\Jenkins\plugins" folder on the (Offline Jenkins) server
• Restart Jenkins and voila! It should be installed.

For external keystores, prefix with "file:"

server.ssl.key-store=file:config/keystore 

Bootstrap 4, 2019

I read a lot of these answers but I ended up doing it myself because it was just not what i needed.

I have Bootstrap 4, and want to keep the click + the hover functionality. Besides I want to enable it only on dropdowns that have an extra class ".open-on-hover".

I also want to keep the Bootstrap's Jquery that positions the dropdown when it is next to the edge of the page. So we don't just want to do "display: block". We want the full Bootstrap's way of working. So I just trigger click.

The logic is "If it is a mouseenter then open it, if it is a mouseleave then hide it if it is open"

/**
 * Open Bootstrap 4 dropdown on hover
 */
$(document).on('mouseenter mouseleave', '.dropdown.open-on-hover', function(e) 
{
    let toggler = $(this).find('[data-toggle="dropdown"]').first();

    if(e.type === 'mouseenter') {
        $(toggler).trigger('click', 'open');
    } else if ($(this).children('.dropdown-menu.show').length) {
        $(toggler).trigger('click', 'close');
    }
});

The html

<div class="dropdown open-on-hover">
    <div class="btn" data-toggle="dropdown">
        Hover or click me
    </div>
    <div class="dropdown-menu">
        <a class="dropdown-item">
            Item 1
        </a>
        <a class="dropdown-item">
            Item 2
        </a>
    </div>
</div>

Use

<string name="win_percentage">%d%% wins</string>

to get

80% wins as a formatted string.

I'm using String.format() method to get the number inserted instead of %d.

Select the Body using chrome dev tools (Inspect ) and change in css overflow:visible,

If that doesn't work then check in below css file if html, body is set as overflow:hidden , change it as visible

Another solution i´ve used is to move the button instead of disabling it. In that case you don´t have those "disable" problems. Finally what you really want is people not to press twice, if the button is not there they can´t do it.

You may also replace it with another button.

var output = emails.Where(e => domains.All(d => !e.EndsWith(d)));

Or if you prefer:

var output = emails.Where(e => !domains.Any(d => e.EndsWith(d)));

Simply use:

$(".parent a[id]");

An alternate is to use a new helper function which will take values from List and update in the DataGridView as following:

    private void DisplayStringListInDataGrid(List<string> passedList, ref DataGridView gridToUpdate, string newColumnHeader)
    {
        DataTable gridData = new DataTable();
        gridData.Columns.Add(newColumnHeader);

        foreach (string listItem in passedList)
        {
            gridData.Rows.Add(listItem);
        }

        BindingSource gridDataBinder = new BindingSource();
        gridDataBinder.DataSource = gridData;
        dgDataBeingProcessed.DataSource = gridDataBinder;
    }

Then we can call this function the following way:

    DisplayStringListInDataGrid(<nameOfListWithStrings>, ref <nameOfDataGridViewToDisplay>, <nameToBeGivenForTheNewColumn>);

I know this is an old thread, but I wanted to call out that API for getting the PID (as well as other manipulation of the Java process at runtime) is being added to the Process class in JDK 9: http://openjdk.java.net/jeps/102

RouteParams are now deprecated , So here is how to do it in the new router.

this.router.navigate(['/login'],{ queryParams: { token:'1234'}})

And then in the login component you can take the parameter,

constructor(private route: ActivatedRoute) {}
ngOnInit() {
    // Capture the token  if available
    this.sessionId = this.route.queryParams['token']

}

Here is the documentation

How about this:

EXECUTE xp_regread @rootkey='HKEY_LOCAL_MACHINE',
                   @key='SOFTWARE\Microsoft\Microsoft SQL Server\Instance Names\SQl',
                   @value_name='MSSQLSERVER'

This will get the instance name as well. null means default instance:

SELECT SERVERPROPERTY ('InstanceName')

http://technet.microsoft.com/en-us/library/ms174396.aspx

Sometime we might don't want to apply ordering on our result set to add serial number. But if we are going to use ROW_NUMBER() then we have to have a ORDER BY clause. So, for that we can simply apply a tricks to avoid any ordering on the result set.

SELECT ROW_NUMBER() OVER(ORDER BY (SELECT 1)) AS ItemNo, ItemName FROM ItemMastetr

For that we don't need to apply order by on our result set. We'll just add ItemNo on our given result set.

You can cast the int to an enum

(MyColour)2

There is also the option of Enum.Parse

(MyColour)Enum.Parse(typeof(MyColour), "Red")

If the array is unsorted, there isn't really a better way (aside from using the above-mentioned indexOf, which I think amounts to the same thing). If the array is sorted, you can do a binary search, which works like this:

1. Pick the middle element of the array.
2. Is the element you're looking for bigger than the element you picked? If so, you've eliminated the bottom half of the array. If it isn't, you've eliminated the top half.
3. Pick the middle element of the remaining half of the array, and continue as in step 2, eliminating halves of the remaining array. Eventually you'll either find your element or have no array left to look through.

Binary search runs in time proportional to the logarithm of the length of the array, so it can be much faster than looking at each individual element.

Create your list before your loop, else it will be created at each loop.

>>> list1 = []
>>> for i in range(10) :
...   list1.append( range(i,10) )
...
>>> list1
[[0, 1, 2, 3, 4, 5, 6, 7, 8, 9], [1, 2, 3, 4, 5, 6, 7, 8, 9], [2, 3, 4, 5, 6, 7, 8, 9], [3, 4, 5, 6, 7, 8, 9], [4, 5, 6, 7, 8, 9], [5, 6, 7, 8, 9], [6, 7, 8, 9], [7, 8, 9], [8, 9], [9]]

You can use the DateTime.Add() method to add the time to the date.

DateTime date = DateTime.Now;
TimeSpan time = new TimeSpan(36, 0, 0, 0);
DateTime combined = date.Add(time);
Console.WriteLine("{0:dddd}", combined);

You can also create your timespan by parsing a String, if that is what you need to do.

Alternatively, you could look at using other controls. You didn't mention if you are using winforms, wpf or asp.net, but there are various date and time picker controls that support selection of both date and time.

As a follow on, you could select "all nodes with a particular attribute" like this:

//*[@id='4']

DEMO: Resizing images with JS and HTML Canvas Demo fiddler.

You may find 3 different methods to do this resize, that will help you understand how the code is working and why.

https://jsfiddle.net/1b68eLdr/93089/

Full code of both demo, and TypeScript method that you may want to use in your code, can be found in the GitHub project.

https://github.com/eyalc4/ts-image-resizer

This is the final code:

export class ImageTools {
base64ResizedImage: string = null;

constructor() {
}

ResizeImage(base64image: string, width: number = 1080, height: number = 1080) {
    let img = new Image();
    img.src = base64image;

    img.onload = () => {

        // Check if the image require resize at all
        if(img.height <= height && img.width <= width) {
            this.base64ResizedImage = base64image;

            // TODO: Call method to do something with the resize image
        }
        else {
            // Make sure the width and height preserve the original aspect ratio and adjust if needed
            if(img.height > img.width) {
                width = Math.floor(height * (img.width / img.height));
            }
            else {
                height = Math.floor(width * (img.height / img.width));
            }

            let resizingCanvas: HTMLCanvasElement = document.createElement('canvas');
            let resizingCanvasContext = resizingCanvas.getContext("2d");

            // Start with original image size
            resizingCanvas.width = img.width;
            resizingCanvas.height = img.height;


            // Draw the original image on the (temp) resizing canvas
            resizingCanvasContext.drawImage(img, 0, 0, resizingCanvas.width, resizingCanvas.height);

            let curImageDimensions = {
                width: Math.floor(img.width),
                height: Math.floor(img.height)
            };

            let halfImageDimensions = {
                width: null,
                height: null
            };

            // Quickly reduce the size by 50% each time in few iterations until the size is less then
            // 2x time the target size - the motivation for it, is to reduce the aliasing that would have been
            // created with direct reduction of very big image to small image
            while (curImageDimensions.width * 0.5 > width) {
                // Reduce the resizing canvas by half and refresh the image
                halfImageDimensions.width = Math.floor(curImageDimensions.width * 0.5);
                halfImageDimensions.height = Math.floor(curImageDimensions.height * 0.5);

                resizingCanvasContext.drawImage(resizingCanvas, 0, 0, curImageDimensions.width, curImageDimensions.height,
                    0, 0, halfImageDimensions.width, halfImageDimensions.height);

                curImageDimensions.width = halfImageDimensions.width;
                curImageDimensions.height = halfImageDimensions.height;
            }

            // Now do final resize for the resizingCanvas to meet the dimension requirments
            // directly to the output canvas, that will output the final image
            let outputCanvas: HTMLCanvasElement = document.createElement('canvas');
            let outputCanvasContext = outputCanvas.getContext("2d");

            outputCanvas.width = width;
            outputCanvas.height = height;

            outputCanvasContext.drawImage(resizingCanvas, 0, 0, curImageDimensions.width, curImageDimensions.height,
                0, 0, width, height);

            // output the canvas pixels as an image. params: format, quality
            this.base64ResizedImage = outputCanvas.toDataURL('image/jpeg', 0.85);

List.equals()

http://java.sun.com/j2se/1.5/docs/api/java/util/List.html#equals(java.lang.Object)

I'm using

Sheet1.Range("E2", "E3000").NumberFormat = "dd/mm/yyyy hh:mm:ss"

to format a column

So I guess

Sheet1.Range("E2", "E3000").NumberFormat = "MMM dd yyyy"

would do the trick for you.

More: NumberFormat function.

I know this is an old one but it comes up top of Google and all the links provided now seem out of date.

This is the latest list of types Facebook accepts: https://developers.facebook.com/docs/reference/opengraph

If you don't use one of these then the type will default to 'website' which is best used for home pages/summarising a web site.

In answer to the OP you would now want to use a place which will allow you to add lat/long location details.

This code can be useful for you:

A PIL only solution for creating a bi-level (black and white) image with a custom threshold:

from PIL import Image
img = Image.open('mB96s.png')
thresh = 200
fn = lambda x : 255 if x > thresh else 0
r = img.convert('L').point(fn, mode='1')
r.save('foo.png')

With just

r = img.convert('1')
r.save('foo.png')

you get a dithered image.

From left to right the input image, the black and white conversion result and the dithered result:

You can click on the images to view the unscaled versions.

That is the release version of RHEL, or at least the release of RHEL from which the package supplying /etc/redhat-release was installed. A file like that is probably the closest you can come; you could also look at /etc/lsb-release.

It is theoretically possible to have packages installed from a mix of versions (e.g. upgrading part of the system to 5.5 while leaving other parts at 5.4), so if you depend on the versions of specific components you will need to check for those individually.

Given that your date format follows : "YYYY-MM-DD HH:MM:SS", if you need to find the difference between two dates in number of months :

(strftime('%m', date1) + 12*strftime('%Y', date1)) - (strftime('%m', date2) + 12*strftime('%Y', date2))

Like this:

<c:forEach var="entry" items="${myMap}">
  Key: <c:out value="${entry.key}"/>
  Value: <c:out value="${entry.value}"/>
</c:forEach>

If you just want to remove any duplicate paths, I use this script I wrote a while back since I was having trouble with multiple perl5/bin paths:

#!/bin/bash
#
# path-cleanup
#
# This must be run as "source path-cleanup" or ". path-cleanup"
# so the current shell gets the changes.

pathlist=`echo $PATH | sed 's/:/\n/g' | uniq`

# echo "Starting PATH: $PATH"
# echo "pathlist: $pathlist"
unset PATH
# echo "After unset, PATH: $PATH"
for dir in $pathlist
do
    if test -d $dir ; then
        if test -z $PATH; then
            PATH=$dir
        else
            PATH=$PATH:$dir
        fi
    fi
done
export PATH
# echo "After loop, PATH: $PATH"

And I put it in my ~/.profile at the end. Since I use BASH almost exclusively, I haven't tried it in other shells.

WWW FAQs: What is the maximum length of a URL? has its own answer based on empirical testing and research. The short answer is that going over 2048 characters makes Internet Explorer unhappy and thus this is the limit you should use. See the page for a long answer.

Expanding on zoul's answer:

If you want to setup Vim to use specific settings when editing a particular filetype, you'll want to use autocommands:

autocmd Filetype css setlocal tabstop=4

This will make it so that tabs are displayed as 4 spaces. Setting expandtab will cause Vim to actually insert spaces (the number of them being controlled by tabstop) when you press tab; you might want to use softtabstop to make backspace work properly (that is, reduce indentation when that's what would happen should tabs be used, rather than always delete one char at a time).

To make a fully educated decision as to how to set things up, you'll need to read Vim docs on tabstop, shiftwidth, softtabstop and expandtab. The most interesting bit is found under expandtab (:help 'expandtab):

There are four main ways to use tabs in Vim:

1. Always keep 'tabstop' at 8, set 'softtabstop' and 'shiftwidth' to 4 (or 3 or whatever you prefer) and use 'noexpandtab'. Then Vim will use a mix of tabs and spaces, but typing and will behave like a tab appears every 4 (or 3) characters.

2. Set 'tabstop' and 'shiftwidth' to whatever you prefer and use 'expandtab'. This way you will always insert spaces. The formatting will never be messed up when 'tabstop' is changed.

3. Set 'tabstop' and 'shiftwidth' to whatever you prefer and use a |modeline| to set these values when editing the file again. Only works when using Vim to edit the file.

4. Always set 'tabstop' and 'shiftwidth' to the same value, and 'noexpandtab'. This should then work (for initial indents only) for any tabstop setting that people use. It might be nice to have tabs after the first non-blank inserted as spaces if you do this though. Otherwise aligned comments will be wrong when 'tabstop' is changed.

GetType() exists on every single framework type, because it is defined on the base object type. So, regardless of the type itself, you can use it to return the underlying Type

So, all you need to do is:

u.GetType() == t

I would definitely suggest using element.getBoundingClientRect().

https://developer.mozilla.org/en-US/docs/Web/API/element.getBoundingClientRect

Summary

Returns a text rectangle object that encloses a group of text rectangles.

Syntax

var rectObject = object.getBoundingClientRect();

Returns

The returned value is a TextRectangle object which is the union of the rectangles returned by getClientRects() for the element, i.e., the CSS border-boxes associated with the element.

The returned value is a TextRectangle object, which contains read-only left, top, right and bottom properties describing the border-box, in pixels, with the top-left relative to the top-left of the viewport.

Here's a browser compatibility table taken from the linked MDN site:

+---------------+--------+-----------------+-------------------+-------+--------+
|    Feature    | Chrome | Firefox (Gecko) | Internet Explorer | Opera | Safari |
+---------------+--------+-----------------+-------------------+-------+--------+
| Basic support | 1.0    | 3.0 (1.9)       | 4.0               | (Yes) | 4.0    |
+---------------+--------+-----------------+-------------------+-------+--------+

It's widely supported, and is really easy to use, not to mention that it's really fast. Here's a related article from John Resig: http://ejohn.org/blog/getboundingclientrect-is-awesome/

You can use it like this:

var logo = document.getElementById('hlogo');
var logoTextRectangle = logo.getBoundingClientRect();

console.log("logo's left pos.:", logoTextRectangle.left);
console.log("logo's right pos.:", logoTextRectangle.right);

Here's a really simple example: http://jsbin.com/awisom/2 (you can view and edit the code by clicking "Edit in JS Bin" in the upper right corner).

Or here's another one using Chrome's console:

Note:

I have to mention that the width and height attributes of the getBoundingClientRect() method's return value are undefined in Internet Explorer 8. It works in Chrome 26.x, Firefox 20.x and Opera 12.x though. Workaround in IE8: for width, you could subtract the return value's right and left attributes, and for height, you could subtract bottom and top attributes (like this).

In my case:

<html>
 <head>
  <script type="text/javascript">

    function changeFunction(val) {

       //Show option value
       console.log(val.value);
    }

  </script>
 </head>
 <body>
   <select id="selectBox" onchange="changeFunction(this)">
     <option value="1">Option #1</option>
     <option value="2">Option #2</option>
   </select>
 </body>
</html>

It is possible to turn the string into a stream by using the std::stringstream class (its constructor takes a string as parameter). Once it's built, you can use the >> operator on it (like on regular file based streams), which will extract, or tokenize word from it:

#include <iostream>
#include <sstream>

using namespace std;

Most of the answers fail here, when process list exceeds 20 processes. That is top -p option limit. For those with older top that does not support filtering with o options, here is a scriptable example to get full screen/console outuput (summary information is missing from this output).

__keyword="YOUR_FILTER" ; ( FILL=""; for i in  $( seq 1 $(stty size|cut -f1 -d" ")); do FILL=$'\n'$FILL; done ;  while :; do HSIZE=$(( $(stty size|cut -f1 -d" ")  - 1 ));  (top -bcn1 | grep "$__keyword"; echo "$FILL" )|head -n$HSIZE; sleep 1;done )

Some explanations

__keyword = your grep filter keyword
HSIZE=console height
FILL=new lines to fill the screen if list is shorter than console height
top -bcn1 = batch, full commandline, repeat once

Try the following:

CONVERT(VARCHAR(10),GetDate(),102)

Then you would need to replace the "." with "-".

The option 1 sounds not too efficient. What if there is no space in the client to do a clone and then remove the .git folder?

Today I found myself trying to do this, where the client is a Raspberry Pi with almost no space left. Furthermore, I also want to exclude some heavy folder from the repository.

Option 2 and others answers here do not help in this scenario. Neither git archive (because require to commit a .gitattributes file, and I don't want to save this exclusion in the repository).

Here I share my solution, similar to option 3, but without the need of git clone:

tmp=`mktemp`
git ls-tree --name-only -r HEAD > $tmp
rsync -avz --files-from=$tmp --exclude='fonts/*' . raspberry:

Changing the rsync line for an equivalent line for compress will also work as a git archive but with a sort of exclusion option (as is asked here).

In my case the error was on a module of my project.I have resolved this with adding

    implementation 'com.android.support:support-v4:20.0.+'
}

I've done this, "parsing" a json response for a particular value, as follows:

curl $url | grep $var | awk '{print $2}' | sed s/\"//g 

Clearly, $url here would be the twitter url, and $var would be "text" to get the response for that var.

Really, I think the only thing I'm doing the OP has left out is grep for the line with the specific variable he seeks. Awk grabs the second item on the line, and with sed I strip the quotes.

Someone smarter than I am could probably do the whole think with awk or grep.

Now, you could do it all with just sed:

curl $url | sed '/text/!d' | sed s/\"text\"://g | sed s/\"//g | sed s/\ //g

thus, no awk, no grep...I don't know why I didn't think of that before. Hmmm...

As you noticed, this exception isn't a real problem. It happens during the boot, when Hibernate tries to retrieve some meta information from the database. If this annoys you, you can disable it:

I just wanted to supplement MajesticRa's recommendation of OxyPlot, and point out how OxyPlot can be used for a variety of plotting cases. The software is free and Open-Source, very polished, and allows for a variety of uses beyon normal 2D mapping.

I've been using OxyPlot for an unorthodox project, where I display (in WPF/C#) a map (Robotic Occupancy Grid) which I could overlay with LineSeries (Path Traveled) and PointSeries (Way Points). Using the OxyPlot ImageAnnotation feature I am able to display 60Hz Video within my OxyPlot, by periodically updating the ImageAnnotation on its own thread, while mapping Series of points overtop the video. The background video and points are even scalable and translatable.

Hopefully this is helpful for other looking to display plots overtop of images and videos.

ArrayList<ArrayList<String>> listOLists = new ArrayList<ArrayList<String>>();
ArrayList<String> singleList = new ArrayList<String>();
singleList.add("hello");
singleList.add("world");
listOLists.add(singleList);

ArrayList<String> anotherList = new ArrayList<String>();
anotherList.add("this is another list");
listOLists.add(anotherList);

When you overload in TypeScript, you only have one implementation with multiple signatures.

class Foo {
    myMethod(a: string);
    myMethod(a: number);
    myMethod(a: number, b: string);
    myMethod(a: any, b?: string) {
        alert(a.toString());
    }
}

Only the three overloads are recognized by TypeScript as possible signatures for a method call, not the actual implementation.

In your case, I would personally use two methods with different names as there isn't enough commonality in the parameters, which makes it likely the method body will need to have lots of "ifs" to decide what to do.

TypeScript 1.4

As of TypeScript 1.4, you can typically remove the need for an overload using a union type. The above example can be better expressed using:

myMethod(a: string | number, b?: string) {
    alert(a.toString());
}

The type of a is "either string or number".

I have solved this if you are using array called for 2 tables. Example you have, $tableA['yellow'] and $tableA['blue'] . You are getting these 2 values and you want to add another element inside them to separate them by their type.

foreach ($tableA['yellow'] as $value) {
    $value->type = 'YELLOW';  //you are adding new element named 'type'
}

foreach ($tableA['blue'] as $value) {
    $value->type = 'BLUE';  //you are adding new element named 'type'
}

So, both of the tables value will have new element called type.

I strongly do NOT recommend to use < modules runAllManagedModulesForAllRequests="true">. This leads all requests (even .jpg, .css, .pdf, etc) will be processed by all registered HTTP modules. There are two negative moments: a) additional load on hardware resources; b) potential errors, as http modules will process new type of content.

with this solution:

for(int i = dtPerson.Rows.Count-1; i >= 0; i--) 
{ 
    DataRow dr = dtPerson.Rows[i]; 
    if (dr["name"] == "Joe")
        dr.Delete();
} 

if you are going to use the datatable after deleting the row, you will get an error. So what you can do is: replace dr.Delete(); with dtPerson.Rows.Remove(dr);

Arrays have a property .length that returns the number of elements.

var st =
    {
        "itema":{},
        "itemb":
        [
            {"id":"s01","cd":"c01","dd":"d01"},
            {"id":"s02","cd":"c02","dd":"d02"}
        ]
    };

st.itemb.length // 2

Yeap, you just need to make . match newline :

$string =~ /(START)(.+?)(END)/s;

SELECT name
FROM sys.objects
WHERE type = 'P'
AND (DATEDIFF(D,modify_date, GETDATE()) < 7
     OR DATEDIFF(D,create_date, GETDATE()) < 7)

This is probably the easiest way:

new Date(<your-date-object>.toDateString());

Example: To get the Current Date without time component:

new Date(new Date().toDateString());

gives: Thu Jul 11 2019 00:00:00 GMT-0400 (Eastern Daylight Time)

Note this works universally, because toDateString() produces date string with your browser's localization (without the time component), and the new Date() uses the same localization to parse that date string.

#!/usr/bin/env python
# -*- coding: utf-8 -*-

s = u"6Â 918Â 417Â 712"
s = s.replace(u"Â", "") 
print s

This will print out 6 918 417 712

    os.system('cls' if os.name=='nt' else 'clear')

You can now use RPC libraries that support Python and Javascript such as zerorpc

From their front page:

Node.js Client

var zerorpc = require("zerorpc");

var client = new zerorpc.Client();
client.connect("tcp://127.0.0.1:4242");

client.invoke("hello", "RPC", function(error, res, more) {
    console.log(res);
});

Python Server

import zerorpc

class HelloRPC(object):
    def hello(self, name):
        return "Hello, %s" % name

s = zerorpc.Server(HelloRPC())
s.bind("tcp://0.0.0.0:4242")
s.run()

mystring = mystring.replace(/["']/g, "");

You probably need to either open up the port to access it in your LAN (or outside of it) or bind the network address to the port (make PostgreSQL listen on your LAN instead of just on localhost)

That's right, if you're on a mac(unix) you won't see .git in finder(the file browser). You can follow the directions above to delete and there are git commands that allow you to delete files as well(they are sometimes difficult to work with and learn, for example: on making a 'git rm -r ' command you might be prompted with a .git/ not found. Here is the git command specs:

usage: git rm [options] [--] ...

-n, --dry-run         dry run
-q, --quiet           do not list removed files
--cached              only remove from the index
-f, --force           override the up-to-date check
-r                    allow recursive removal
--ignore-unmatch      exit with a zero status even if nothing matched

When I had to do this, deleting the objects and refs didn't matter. After I deleted the other files in the .git, I initialized a git repo with 'git init' and it created an empty repo.

I also encountered this situation when I was trying to train a KNN classifier. but it seems that the warning was gone after I changed:
knn.fit(X_train,y_train)
to
knn.fit(X_train, np.ravel(y_train,order='C'))

Ahead of this line I used import numpy as np.

I installed the Role plugin under Jenkins-3.5, but it does not show the "Manage Roles" option under "Manage Jenkins", and when one follows the security install page from the wiki, all users are locked out instantly. I had to manually shutdown Jenkins on the server, restore the correct configuration settings (/me is happy to do proper backups) and restart Jenkins.

I didn't have high hopes, as that plugin was last updated in 2011

You could try this:

{% if not profile.user.first_name.value %}
  <p> -- </p>
{% else %}
  {{ profile.user.first_name }} {{ profile.user.last_name }}
{% endif %}

This way, you're essentially checking to see if the form field first_name has any value associated with it. See {{ field.value }} in Looping over the form's fields in Django Documentation.

I'm using Django 3.0.

Add pointer-events: none; to the overlay.

Original answer: My suggestion would be that you could capture the click event with the overlay, hide the overlay, then refire the click event, then display the overlay again. I'm not sure if you'd get a flicker effect though.

[Update] Exactly this problem and exactly my solution just appeared in this post: "Forwarding Mouse Events Through Layers". I know its probably a little late for the OP, but for the sake of somebody having this problem in the future, I though I would include it.

Reasons of the warning are already described, but how would you fix the warning? You have to seal either class or virtual member.

  class B
  {
    protected virtual void Foo() { }
  }

  class A : B
  {
    public A()
    {
      Foo(); // warning here
    }
  }

You can seal class A:

  sealed class A : B
  {
    public A()
    {
      Foo(); // no warning
    }
  }

Or you can seal method Foo:

  class A : B
  {
    public A()
    {
      Foo(); // no warning
    }

    protected sealed override void Foo()
    {
      base.Foo();
    }
  }

Binary Search :

// List - values inside list
// searchItem - Item to search
// size - Size of list
// upperBound - higher index of list
// lowerBound - lower index of list
def binarySearch(list, searchItem, size, upperBound, lowerBound):
        print(list)
        print(upperBound)
        print(lowerBound)
        mid = ((upperBound + lowerBound)) // 2
        print(mid)
        if int(list[int(mid)]) == value:
               return "value exist"
        elif int(list[int(mid)]) < value:
             return searchItem(list, value, size, upperBound, mid + 1)
        elif int(list[int(mid)]) > value:
               return searchItem(list, value, size, mid - 1, lowerBound)

// To call above function use :

list = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
searchItem = 1        
print(searchItem(list[0], item, len(list[0]) -1, len(list[0]) - 1, 0))

Check your git repo before committing

gitrepo/.git/hooks/commit-msg

if this file is not present in that location then you will get this error "missing Change-Id in commit message" .

To solve this just copy paste the commit hook in .git folder.

I faced this same issue when I needed to load location data that I had serialized into the database from the google places API. Generally I would want the whole thing so it works with maps but I didn't want to have to specify all of the fields every time.

I was working in Ruby so I can't give you the PHP implementation but the principle should be the same.

I defined a custom scalar type called JSON which just returns a literal JSON object.

The ruby implementation was like so (using graphql-ruby)

module Graph
  module Types
    JsonType = GraphQL::ScalarType.define do
      name "JSON"
      coerce_input -> (x) { x }
      coerce_result -> (x) { x }
    end
  end
end

Then I used it for our objects like so

field :location, Types::JsonType

I would use this very sparingly though, using it only where you know you always need the whole JSON object (as I did in my case). Otherwise it is defeating the object of GraphQL more generally speaking.

As Brad Wilson states in his answer here:

ModelState.IsValid tells you if any model errors have been added to ModelState.

The default model binder will add some errors for basic type conversion issues (for example, passing a non-number for something which is an "int"). You can populate ModelState more fully based on whatever validation system you're using.

Try using :-

if (!ModelState.IsValid)
{
    var errors = ModelState.SelectMany(x => x.Value.Errors.Select(z => z.Exception));

    // Breakpoint, Log or examine the list with Exceptions.
}

If it helps catching you the error. Courtesy this and this

What about performance?

1. Always debounce events to reduce calculations
2. Use scope.applyAsync to reduce overall digest cycles count

function debounce(func, wait) {
    var timeout;
    return function () {
        var context = this, args = arguments;
        var later = function () {
            timeout = null;
            func.apply(context, args);
        };

        if (!timeout) func.apply(context, args);
        clearTimeout(timeout);
        timeout = setTimeout(later, wait);
    };
}

angular.module('app.layout')
  .directive('classScroll', function ($window) {    
    return {
        restrict: 'A',
        link: function (scope, element) {    
            function toggle() {
                angular.element(element)
                  .toggleClass('class-scroll--scrolled', 
                    window.pageYOffset > 0);
                scope.$applyAsync();
            }    
            angular.element($window)
              .on('scroll', debounce(toggle, 50));

            toggle();
        }
    };
});

3. If you don't need to trigger watchers/digests at all then use compile

.directive('classScroll', function ($window, utils) {
    return {
        restrict: 'A',
        compile: function (element, attributes) {
            function toggle() {
                angular.element(element)
                  .toggleClass(attributes.classScroll,
                    window.pageYOffset > 0);
            }

            angular.element($window)
              .on('scroll', utils.debounce(toggle, 50));
            toggle();
        }
    };
  });

And you can use it like <header class-scroll="header--scrolled">

If you are working with form validation. Then in this case form send string. I used following code to check either form input is a decimal number or not. I hope this will work for you too.

function is_decimal($input = '') {

    $alphabets = str_split($input);
    $find = array('0','1','2','3','4','5','6','7','8','9','.'); // Please note: All intiger numbers are decimal. If you want to check numbers without point "." then you can remove '.' from array. 

    foreach ($alphabets as $key => $alphabet) {
        if (!in_array($alphabet, $find)) {
            return false;
        }
    }

    // Check if user has enter "." point more then once.
    if (substr_count($input, ".") > 1) {
        return false;
    }

    return true;
}

Ugg! This turned out to simply be a Java version issue for me. I got the handshake error using JRE 1.6 and everything worked perfectly using JRE 1.8.0_144.

To answer your titular question, you use [0] to access the first element, but as it stands mandrill_events contains a string not an array, so mandrill_events[0] will just get you the first character, '['.

So either correct your source to:

var req = { mandrill_events: [{"event":"inbound","ts":1426249238}] };

and then req.mandrill_events[0], or if you're stuck with it being a string, parse the JSON the string contains:

var req = { mandrill_events: '[{"event":"inbound","ts":1426249238}]' };
var mandrill_events = JSON.parse(req.mandrill_events);
var result = mandrill_events[0];

As a side note - there seems to be a bug in the Android API or faulty documentation or maybe I am just plain stupid. The google docs clearly states the following:

Note: Starting with Android 4.0 (API level 14), the Camera.lock() and Camera.unlock() calls are managed for you automatically.

See: http://developer.android.com/guide/topics/media/camera.html

This does not seem to be the case!

After batteling for literaly days without any success and many little problems like "failed to start" kinda errors I decided to manually implement the locking and BAM! everything worked fine.

Im using the genymotion emulator for a 4.1.1 device with a min sdk of 14.

Almost there. In your predicate, you want a relative path, so change

./book[/author/name = 'John'] 

to either

./book[author/name = 'John'] 

or

./book[./author/name = 'John'] 

and you will match your element. Your current predicate goes back to the root of the document to look for an author.

Paths specified with a . are relative to the current working directory, not relative to the script file. So the file might be found if you run node app.js but not if you run node folder/app.js. The only exception to this is require('./file') and that is only possible because require exists per-module and thus knows what module it is being called from.

To make a path relative to the script, you must use the __dirname variable.

var path = require('path');

path.join(__dirname, 'path/to/file')

or potentially

path.join(__dirname, 'path', 'to', 'file')

Parallel GC

• XX:+UseParallelGC Use parallel garbage collection for scavenges. (Introduced in 1.4.1)
• XX:+UseParallelOldGC Use parallel garbage collection for the full collections. Enabling this option automatically sets -XX:+UseParallelGC. (Introduced in 5.0 update 6.)

UseParNewGC

UseParNewGC A parallel version of the young generation copying collector is used with the concurrent collector (i.e. if -XX:+ UseConcMarkSweepGC is used on the command line then the flag UseParNewGC is also set to true if it is not otherwise explicitly set on the command line).

Perhaps the easiest way to understand was combinations of garbage collection algorithms made by Alexey Ragozin

<table border="1" style="width:100%">_x000D_

    <td align="center">Young collector</td>_x000D_

Conclusion:

1. Apply -XX:+UseParallelGC when you require parallel collection method over YOUNG generation ONLY, (but still) use serial-mark-sweep method as OLD generation collection
2. Apply -XX:+UseParallelOldGC when you require parallel collection method over YOUNG generation (automatically sets -XX:+UseParallelGC) AND OLD generation collection
3. Apply -XX:+UseParNewGC & -XX:+UseConcMarkSweepGC when you require parallel collection method over YOUNG generation AND require CMS method as your collection over OLD generation memory
4. You can't apply -XX:+UseParallelGC or -XX:+UseParallelOldGC with -XX:+UseConcMarkSweepGC simultaneously, that's why your require -XX:+UseParNewGC to be paired with CMS otherwise use -XX:+UseSerialGC explicitly OR -XX:-UseParNewGC if you wish to use serial method against young generation

If you are running your application just on localhost and it is not yet live, I believe it is very difficult to send mail using this.

Once you put your application online, I believe that this problem should be automatically solved. By the way,ini_set() helps you to change the values in php.ini during run time.

This is the same question as Failed to connect to mailserver at "localhost" port 25

also check this php mail function not working

you need to call the function like this

$this->assign()

instead of just assign()

First, you need to understand the difference between window and document. The window object is a top level client side object. There is nothing above the window object. JavaScript is an object orientated language. You start with an object and apply methods to its properties or the properties of its object groups. For example, the document object is an object of the window object. To change the document's background color, you'd set the document's bgcolor property.

window.document.bgcolor = "red" 

To answer your question, There is no difference in the end result between window and document scrollTop. Both will give the same output.

Check working example at http://jsfiddle.net/7VRvj/6/

In general use document mainly to register events and use window to do things like scroll, scrollTop, and resize.

Sometimes the formatting is different in a cell when using print(res), but jupyter/ipython comes with a display. See an example of the formatting difference using pandas below.

%%time
import pandas as pd 
from IPython.display import display

df = pd.DataFrame({"col0":{"a":0,"b":0}
              ,"col1":{"a":1,"b":1}
              ,"col2":{"a":2,"b":2}
             })

#compare the following
print(df)
display(df)

The display statement can preserve the formatting.

The error comes when you try to call sum(x) and x is a factor.

What that means is that one of your columns, though they look like numbers are actually factors (what you are seeing is the text representation)

simple fix, convert to numeric. However, it needs an intermeidate step of converting to character first. Use the following:

family[, 1] <- as.numeric(as.character( family[, 1] ))
family[, 3] <- as.numeric(as.character( family[, 3] ))

For a detailed explanation of why the intermediate as.character step is needed, take a look at this question: How to convert a factor to integer\numeric without loss of information?

from jquery api

Added to jQuery in version 1.4, the .delay() method allows us to delay the execution of functions that follow it in the queue. It can be used with the standard effects queue or with a custom queue. Only subsequent events in a queue are delayed; for example this will not delay the no-arguments forms of .show() or .hide() which do not use the effects queue.

http://api.jquery.com/delay/

Very simple and surprisingly fast: (without numpy or pandas)

    str( myDate ) == 'NaT'            # True if myDate is NaT

Ok, it's a little nasty, but given the ambiguity surrounding 'NaT' it does the job nicely.

It's also useful when comparing two dates either of which might be NaT as follows:

   str( date1 ) == str( date1 )       # True
   str( date1 ) == str( NaT )         # False
   str( NaT )   == str( date1 )       # False

wait for it...

   str( NaT )   == str( Nat )         # True    (hooray!)

It worked for me to add a class name to the input and then apply CSS rules to that:

<input type="text" name="product" class="product" />

<style>
input[value=""].product {
    display: none;
}
</style>

At least in IE, it has a little difference on local file:

document.URL will return "file://C:\projects\abc\a.html"

but window.location.href will return "file:///C:/projects/abc/a.html"

One is back slash, one is forward slash.

If you go to the Flat file connection manager under Advanced and Look at the "OutputColumnWidth" description's ToolTip It will tell you that Composit characters may use more spaces. So the "é" in "Société" most likely occupies more than one character.

EDIT: Here's something about it: http://en.wikipedia.org/wiki/Precomposed_character

Swift - 5.0

let date = Date()
let formate = date.getFormattedDate(format: "yyyy-MM-dd HH:mm:ss") // Set output formate

extension Date {
   func getFormattedDate(format: String) -> String {
        let dateformat = DateFormatter()
        dateformat.dateFormat = format
        return dateformat.string(from: self)
    }
}

Swift - 4.0

2018-02-01T19:10:04+00:00 Convert Feb 01,2018

extension Date {
    static func getFormattedDate(string: String , formatter:String) -> String{
        let dateFormatterGet = DateFormatter()
        dateFormatterGet.dateFormat = "yyyy-MM-dd'T'HH:mm:ssZ"

        let dateFormatterPrint = DateFormatter()
        dateFormatterPrint.dateFormat = "MMM dd,yyyy"

        let date: Date? = dateFormatterGet.date(from: "2018-02-01T19:10:04+00:00")
        print("Date",dateFormatterPrint.string(from: date!)) // Feb 01,2018
        return dateFormatterPrint.string(from: date!);
    }
}

you can use TextBlock control and assign the text property.

My guess is a wrong version of project A jar in your local maven repository. It seems that the dependency is resolved otherwise I think maven does not start compiling but usually these compiling error means that you have a version mix up. try to make a maven clean install of your project A and see if it changes something for the project B... Also a little more information on your setting could be useful:

• How is maven launched? what command? on a shell, an IDE (using a plugin or not), on a CI server?
• What maven command are you using?

According to http://docs.python.org/dev/py3k/library/stdtypes.html#dictionary-view-objects , the keys(), values() and items() methods of a dict will return corresponding iterators whose orders correspond. However, I am unable to find a reference to the official documentation for python 2.x for the same thing.

So as far as I can tell, the answer is yes, but only in python 3.0+

You're declaring (some of) your event handlers incorrectly:

$('.menuOption').click(function( event ){ // <---- "event" parameter here

    event.preventDefault();
    var categories = $(this).attr('rel');
    $('.pages').hide();
    $(categories).fadeIn();


});

You need "event" to be a parameter to the handlers. WebKit follows IE's old behavior of using a global symbol for "event", but Firefox doesn't. When you're using jQuery, that library normalizes the behavior and ensures that your event handlers are passed the event parameter.

edit — to clarify: you have to provide some parameter name; using event makes it clear what you intend, but you can call it e or cupcake or anything else.

Note also that the reason you probably should use the parameter passed in from jQuery instead of the "native" one (in Chrome and IE and Safari) is that that one (the parameter) is a jQuery wrapper around the native event object. The wrapper is what normalizes the event behavior across browsers. If you use the global version, you don't get that.

After reading the article from Marc Cliament's comment above, I've now changed my all-purpose cross-browser console.log function to look like this:

function log()
{
    "use strict";

    if (typeof(console) !== "undefined" && console.log !== undefined)
    {
        try
        {
            console.log.apply(console, arguments);
        }
        catch (e)
        {
            var log = Function.prototype.bind.call(console.log, console);
            log.apply(console, arguments);
        }
    }
}

<%: DateTime.Today.ToShortDateString() %>

Just Make a single class like, everything will be fine with this:

        @Component
        @Order(Ordered.HIGHEST_PRECEDENCE)
        public class MyCorsConfig implements Filter {

            @Override
            public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) throws IOException, ServletException {
                final HttpServletResponse response = (HttpServletResponse) res;
                response.setHeader("Access-Control-Allow-Origin", "*");
                response.setHeader("Access-Control-Allow-Methods", "POST, PUT, GET, OPTIONS, DELETE");
                response.setHeader("Access-Control-Allow-Headers", "Authorization, Content-Type, enctype");
                response.setHeader("Access-Control-Max-Age", "3600");
                if (HttpMethod.OPTIONS.name().equalsIgnoreCase(((HttpServletRequest) req).getMethod())) {
                    response.setStatus(HttpServletResponse.SC_OK);
                } else {
                    chain.doFilter(req, res);
                }
            }

            @Override
            public void destroy() {
            }

            @Override
            public void init(FilterConfig config) throws ServletException {
            }
        }

Nobody mentioned one crucial difference, ironically answered on a question closed as a duplicated of this.

IEnumerable is read-only and List is not.

See Practical difference between List and IEnumerable

Have you tried using the JQuery change event?

$("#g01-01").change(function() {
    if(this.checked) {
        //Do stuff
    }
});

Then you can also remove onchange="doalert(this.id)" from your checkbox :)

Edit:

I don't know if you are using JQuery, but if you're not yet using it, you will need to put the following script in your page so you can use it:

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script>

This also works:

REPLACE(ISNULL(CONVERT(DATE, @date), ''), '1900-01-01', '') AS 'Your Date Field'

I would follow official projects like tar as an example. In my opinion help msg. needs to be simple and descriptive as possible. Examples of use are good too. There is no real need for "standard help".

I have the following nginx virtual host (static content) for local development work to disable all browser caching:

If you don't want to use Scheduled Tasks you can use the Windows Subsystem for Linux which will allow you to use cron jobs like on Linux.

To make sure cron is actually running you can type service cron status from within the Linux terminal. If it isn't currently running then type service cron start and you should be good to go.

If you need more than one location, you need more than one task. One copy task can copy only from one location (including multiple files) to another one on the node.

- copy: src=/file1 dest=/destination/file1
- copy: src=/file2 dest=/destination/file2

# copy each file over that matches the given pattern
- copy: src={{ item }} dest=/destination/

    - /files/*

To load a .docx file:

    if let htmlFile = Bundle.main.path(forResource: "fileName", ofType: "docx") {
        let url = URL(fileURLWithPath: htmlFile)
        do{
            let data = try Data(contentsOf: url)
            self.webView.load(data, mimeType: "application/vnd.openxmlformats-officedocument.wordprocessingml.document", textEncodingName: "UTF-8", baseURL: url)
        }catch{
            print("errrr")
        }
    }

the implementation in the cpp file should be in the form

gameObject::gameObject()
    {
    x = 0;
    y = 0;
    }
gameObject::gameObject(int inx, int iny)
    {
        x = inx;
        y = iny;
    }

gameObject::~gameObject()
    {
    //
    }
int gameObject::add()
    {
        return x+y;
    }

not within a class gameObject { } definition block

The short answer: no.

The long answer:

Fixed formats work better for HTML emails. In my experience you're best off pretending it's 1999 when it comes to HTML emails. Be explicit and use HTML attributes (width="650") where ever possible in your table definitions, not CSS (style="width:650px"). Use fixed widths, no percentages. A table width of 650 pixels wide is a safe bet. Use inline CSS to set text properties.

It's not a matter of what works in "HTML emails", but rather the plethora of email clients and their limited (and sometimes deliberately so in the case of Gmail, Hotmail etc) ability to render HTML.

This seems to work fine:

<button onclick="location.href='mailto:[email protected]';">send mail</button>

If you're like me you just want to modify some of the colors in AppCompat, and the only color you need to uniquely change in the dialog is the background. Then all you need to do is set a color for colorBackgroundFloating.

Here's my basic theme that simply modifies some colors with no nested themes:

    <style name="AppTheme" parent="Theme.AppCompat">
        <item name="colorPrimary">@color/theme_colorPrimary</item>
        <item name="colorPrimaryDark">@color/theme_colorPrimaryDark</item>
        <item name="colorAccent">@color/theme_colorAccent</item>
        <item name="colorControlActivated">@color/theme_colorControlActivated</item>
        <item name="android:windowBackground">@color/theme_bg</item>
        <item name="colorBackgroundFloating">@color/theme_dialog_bg</item><!-- Dialog background color -->
        <item name="colorButtonNormal">@color/theme_colorPrimary</item>
        <item name="colorControlHighlight">@color/theme_colorAccent</item>
    </style>

My solution is:

import threading, time

def a():
    t = threading.currentThread()
    while getattr(t, "do_run", True):
    print('Do something')
    time.sleep(1)

def getThreadByName(name):
    threads = threading.enumerate() #Threads list
    for thread in threads:
        if thread.name == name:
            return thread

threading.Thread(target=a, name='228').start() #Init thread
t = getThreadByName('228') #Get thread by name
time.sleep(5)
t.do_run = False #Signal to stop thread
t.join()

I solve this by instancing a new instance of depending Object. For an example

instanceA.setInstanceB(new InstanceB());
instanceA.setInstanceB(YOUR NEW VALUE);

By default, the C library buffers the output until it sees a return. To print out the results immediately, use fflush:

while((c=getchar())!= EOF)      
{
    putchar(c);
    fflush(stdout);
}

If none of the above solutions work (nothing worked for me) then just RESTART your computer and you will be able to connect to your sql server (localhost).

Anyway, here is how to fix it:

Use DATEADD in your WHERE clause:

...
WHERE date < DATEADD(day, -30, GETDATE())

You can also use abbreviation d or dd instead of day.

If you want to store the list of ignored files outside of your Git tree, you can use the .git/info/exclude file. It is applied only to your checkout of the repo.

Escape the variable in order to access variables outside of the ssh session: ssh [email protected] "~/tools/myScript.pl \$BUILD_NUMBER"

This will work with "org.bouncycastle.util.encoders.Hex" following package

return new String(Hex.encode(digest));

Its in bouncycastle jar.

Just use the this reference

$(this).attr("id")

or

$(this).prop("id")

I think the best that's possible in cross-browser JavaScript is window.print(), which (in Firefox 3, for me) brings up the 'print' dialog and not the print preview dialog.

FYI, the print dialog is your computer's Print popup, what you get when you do Ctrl-p. The print preview is Firefox's own Preview window, and it has more options. It's what you get with Firefox Menu > Print...

I needed to break some text into paragraphs ("p" tags), so I created a simple helper using some of the recommendations in previous answers (thank you guys).

public static MvcHtmlString ToParagraphs(this HtmlHelper html, string value) 
    { 
        value = html.Encode(value).Replace("\r", String.Empty);
        var arr = value.Split('\n').Where(a => a.Trim() != string.Empty);
        var htmlStr = "<p>" + String.Join("</p><p>", arr) + "</p>";
        return MvcHtmlString.Create(htmlStr);
    }

Usage:

@Html.ToParagraphs(Model.Comments)

The standard time.time() function provides sub-second precision, though that precision varies by platform. For Linux and Mac precision is +- 1 microsecond or 0.001 milliseconds. Python on Windows uses +- 16 milliseconds precision due to clock implementation problems due to process interrupts. The timeit module can provide higher resolution if you're measuring execution time.

>>> import time
>>> time.time()        #return seconds from epoch
1261367718.971009      

Python 3.7 introduces new functions to the time module that provide higher resolution:

>>> import time
>>> time.time_ns()
1530228533161016309
>>> time.time_ns() / (10 ** 9) # convert to floating-point seconds
1530228544.0792289

regex: /^[a-zA-Z0-9_.]$/i

This works

Many suggestions here, most along the lines of git checkout $revision -- $file. A couple of obscure alternatives:

git show $revision:$file > $file

And also, I use this a lot just to see a particular version temporarily:

git show $revision:$file

or

git show $revision:$file | vim -R -

(OBS: $file needs to be prefixed with ./ if it is a relative path for git show $revision:$file to work)

And the even more weird:

git archive $revision $file | tar -x0 > $file

Both methods ensure that your process doesn't end before all of your threads have ended.

The join method has your thread of the main function explicitly wait for all threads that are to be "joined".

The pthread_exit method terminates your main function and thread in a controlled way. main has the particularity that ending main otherwise would be terminating your whole process including all other threads.

For this to work, you have to be sure that none of your threads is using local variables that are declared inside them main function. The advantage of that method is that your main doesn't have to know all threads that have been started in your process, e.g because other threads have themselves created new threads that main doesn't know anything about.

You'll want to have 3 directories inside your chosen GOPATH directory.

GOPATH
     /bin
     /src
       /someProgram
        program.go
       /someLibrary
        library.go
     /pkg

Then you'll run go install from inside either someProgram (which puts an executable in bin) or someLibrary (which puts a library in pkg).

Change secret_string += str(chr(char + 7429146))

To secret_string += chr(ord(char) + 7429146)

ord() converts the character to its Unicode integer equivalent. chr() then converts this integer into its Unicode character equivalent.

Also, 7429146 is too big of a number, it should be less than 1114111

You have to drop the ssh:// prefix when using git clone as an example

git clone [email protected]:owner/repo.git

You can use the net send command to send a message over a network.

example:

net send * How Are You

you can use the above statement to send a message to all members of your domain.But if you want to send a message to a single user named Mike, you can use

 net send mike hello!

this will send hello! to the user named Mike.

Using Windows Authentication

To connect to the database server is recommended to use Windows Authentication, commonly known as integrated security. To specify the Windows authentication, you can use any of the following two key-value pairs with the data provider. NET Framework for SQL Server:

 Integrated Security = true;
 Integrated Security = SSPI;

However, only the second works with the data provider .NET Framework OleDb. If you set Integrated Security = true for ConnectionString an exception is thrown.

To specify the Windows authentication in the data provider. NET Framework for ODBC, you should use the following key-value pair.

Trusted_Connection = yes;

Don't agree with post above. I have a Hero with only English available and I want Spanish.

I installed MoreLocale 2, and it has lots of different languages (Dutch among them). I choose Spanish, Sense UI restarted and EVERYTHING in my phone changed to Spanish: menus, settings, etc. The keyboard predictive text defaulted to Spanish and started suggesting words in Spanish. This means, somewhere within the OS there is a Spanish dictionary hidden and MoreLocale made it available.

The problem is that English is still the only option available in keyboard input language so I can switch to English but can't switch back to Spanish unless I restart Sense UI, which takes a couple of minutes so not a very practical solution.

Still looking for an easier way to do it so please help.

The nature and even existence of file extensions is platform-dependent (some obscure platforms don't even have them, remember) -- in other systems they're only conventional (UNIX and its ilk), while in still others they have definite semantics and in some cases specific limits on length or character content (Windows, etc.).

Since the maintainers have asked that you use ".yaml", that's as close to an "official" ruling as you can get, but the habit of 8.3 is hard to get out of (and, appallingly, still occasionally relevant in 2013).

As a new set of tests to show @EriF89 is still right after all these years:

$ python -m timeit -s "l={k:k for k in xrange(5000)}"    "[i for i in xrange(10000) if i in l]"
1000 loops, best of 3: 1.84 msec per loop
$ python -m timeit -s "l=[k for k in xrange(5000)]"    "[i for i in xrange(10000) if i in l]"
10 loops, best of 3: 573 msec per loop
$ python -m timeit -s "l=tuple([k for k in xrange(5000)])"    "[i for i in xrange(10000) if i in l]"
10 loops, best of 3: 587 msec per loop
$ python -m timeit -s "l=set([k for k in xrange(5000)])"    "[i for i in xrange(10000) if i in l]"
1000 loops, best of 3: 1.88 msec per loop

Here we also compare a tuple, which are known to be faster than lists (and use less memory) in some use cases. In the case of lookup table, the tuple faired no better .

Both the dict and set performed very well. This brings up an interesting point tying into @SilentGhost answer about uniqueness: if the OP has 10M values in a data set, and it's unknown if there are duplicates in them, then it would be worth keeping a set/dict of its elements in parallel with the actual data set, and testing for existence in that set/dict. It's possible the 10M data points only have 10 unique values, which is a much smaller space to search!

SilentGhost's mistake about dicts is actually illuminating because one could use a dict to correlate duplicated data (in values) into a nonduplicated set (keys), and thus keep one data object to hold all data, yet still be fast as a lookup table. For example, a dict key could be the value being looked up, and the value could be a list of indices in an imaginary list where that value occurred.

For example, if the source data list to be searched was l=[1,2,3,1,2,1,4], it could be optimized for both searching and memory by replacing it with this dict:

>>> from collections import defaultdict
>>> d = defaultdict(list)
>>> l=[1,2,3,1,2,1,4]
>>> for i, e in enumerate(l):
...     d[e].append(i)
>>> d
defaultdict(<class 'list'>, {1: [0, 3, 5], 2: [1, 4], 3: [2], 4: [6]})

With this dict, one can know:

1. If a value was in the original dataset (ie 2 in d returns True)
2. Where the value was in the original dataset (ie d[2] returns list of indices where data was found in original data list: [1, 4])

I have seen something like this

private Class<T> persistentClass;

public Constructor() {
    this.persistentClass = (Class<T>) ((ParameterizedType) getClass()
                            .getGenericSuperclass()).getActualTypeArguments()[0];
 }

in the hibernate GenericDataAccessObjects Example

Today I ran into the same error, however, i was using Android Studio 1.0.2. What i did tot fix the problem was that i started a project with minimum SDK 4.4 (API 19) so when i checked the version i noticed that at File->ProjectStructure->app i found Android 5 as a compile SDK Version. I changed that back to 4.4.

You could subscribe for the change and keyup events:

$(function() {
    $(':input').change(myFunction).keyup(myFunction);
});

where myFunction is the function you would like executed:

function myFunction() {
    alert( 'something happened!' );
}

Tools > Options > Query Results > SQL Server > Results to Text (or Grid if you want) > Include columns headers in the result set

You might need to close and reopen SSMS after changing this option.

On the SQL Editor Toolbar you can select save to file without having to restart SSMS

With ECMAScript 2015 you are now able to do it directly in object declaration with the brackets notation: 

var obj = {
  [key]: value
}

Where key can be any sort of expression (e.g. a variable) returning a value.

So here your code would look like:

<something>.stop().animate({
  [thetop]: 10
}, 10)

Where thetop will be evaluated before being used as key.

Update: Google Forms can now upload files. This answer was posted before Google Forms had the capability to upload files.

This solution does not use Google Forms. This is an example of using an Apps Script Web App, which is very different than a Google Form. A Web App is basically a website, but you can't get a domain name for it. This is not a modification of a Google Form, which can't be done to upload a file.

NOTE: I did have an example of both the UI Service and HTML Service, but have removed the UI Service example, because the UI Service is deprecated.

NOTE: The only sandbox setting available is now IFRAME. I you want to use an onsubmit attribute in the beginning form tag: <form onsubmit="myFunctionName()">, it may cause the form to disappear from the screen after the form submission.

If you were using NATIVE mode, your file upload Web App may no longer be working. With NATIVE mode, a form submission would not invoke the default behavior of the page disappearing from the screen. If you were using NATIVE mode, and your file upload form is no longer working, then you may be using a "submit" type button. I'm guessing that you may also be using the "google.script.run" client side API to send data to the server. If you want the page to disappear from the screen after a form submission, you could do that another way. But you may not care, or even prefer to have the page stay on the screen. Depending upon what you want, you'll need to configure the settings and code a certain way.

If you are using a "submit" type button, and want to continue to use it, you can try adding event.preventDefault(); to your code in the submit event handler function. Or you'll need to use the google.script.run client side API.

A custom form for uploading files from a users computer drive, to your Google Drive can be created with the Apps Script HTML Service. This example requires writing a program, but I've provide all the basic code here.

This example shows an upload form with Google Apps Script HTML Service.

What You Need

• Google Account
• Google Drive
• Google Apps Script - also called Google Script

Google Apps Script

There are various ways to end up at the Google Apps Script code editor.

• Load Apps Script directly from the web address: https://script.google.com
• Open a Google Sheet first, then open Apps Script
• Go to your Google Drive, then Open Apps Script: https://drive.google.com/drive/#my-drive
• Go to your Google Drive, then click on an Apps Script project file
• Open Apps Script from Google Docs
• etc

I mention this because if you are not aware of all the possibilities, it could be a little confusing. Google Apps Script can be embedded in a Google Site, Sheets, Docs or Forms, or used as a stand alone app.

Apps Script Overview

This example is a "Stand Alone" app with HTML Service.

HTML Service - Create a web app using HTML, CSS and Javascript

Google Apps Script only has two types of files inside of a Project:

• Script
• HTML

Script files have a .gs extension. The .gs code is a server side code written in JavaScript, and a combination of Google's own API.

• Copy and Paste the following code

• Save It

• Create the first Named Version

• Publish it

• Set the Permissions

  and you can start using it.

Start by:

• Create a new Blank Project in Apps Script
• Copy and Paste in this code:

Upload a file with HTML Service:

Code.gs file (Created by Default)

//For this to work, you need a folder in your Google drive named:
// 'For Web Hosting'
// or change the hard coded folder name to the name of the folder
// you want the file written to

function doGet(e) {
  return HtmlService.createTemplateFromFile('Form')
    .evaluate() // evaluate MUST come before setting the Sandbox mode
    .setTitle('Name To Appear in Browser Tab')
    .setSandboxMode();//Defaults to IFRAME which is now the only mode available
}

function processForm(theForm) {
  var fileBlob = theForm.picToLoad;
  
  Logger.log("fileBlob Name: " + fileBlob.getName())
  Logger.log("fileBlob type: " + fileBlob.getContentType())
  Logger.log('fileBlob: ' + fileBlob);

  var fldrSssn = DriveApp.getFolderById(Your Folder ID);
    fldrSssn.createFile(fileBlob);
    
  return true;
}

Create an html file:

<!DOCTYPE html>
<html>
  <head>
    <base target="_top">
  </head>
  <body>
    <h1 id="main-heading">Main Heading</h1>
    <br/>
    <div id="formDiv">

      <form id="myForm">
    
        <input name="picToLoad" type="file" /><br/>
        <input type="button" value="Submit" onclick="picUploadJs(this.parentNode)" />
          
      </form>
    </div>


  <div id="status" style="display: none">
  <!-- div will be filled with innerHTML after form submission. -->
  Uploading. Please wait...
</div>

</body>
<script>

function picUploadJs(frmData) {

  document.getElementById('status').style.display = 'inline';

  google.script.run
    .withSuccessHandler(updateOutput)
    .processForm(frmData)
};
  // Javascript function called by "submit" button handler,
  // to show results.
  
  function updateOutput() {
  
    var outputDiv = document.getElementById('status');
    outputDiv.innerHTML = "The File was UPLOADED!";
  }

</script>
</html>

This is a full working example. It only has two buttons and one <div> element, so you won't see much on the screen. If the .gs script is successful, true is returned, and an onSuccess function runs. The onSuccess function (updateOutput) injects inner HTML into the div element with the message, "The File was UPLOADED!"

• Save the file, give the project a name
• Using the menu: File, Manage Version then Save the first Version
• Publish, Deploy As Web App then Update

When you run the Script the first time, it will ask for permissions because it's saving files to your drive. After you grant permissions that first time, the Apps Script stops, and won't complete running. So, you need to run it again. The script won't ask for permissions again after the first time.

The Apps Script file will show up in your Google Drive. In Google Drive you can set permissions for who can access and use the script. The script is run by simply providing the link to the user. Use the link just as you would load a web page.

Another example of using the HTML Service can be seen at this link here on StackOverflow:

File Upload with HTML Service

NOTES about deprecated UI Service:

There is a difference between the UI Service, and the Ui getUi() method of the Spreadsheet Class (Or other class) The Apps Script UI Service was deprecated on Dec. 11, 2014. It will continue to work for some period of time, but you are encouraged to use the HTML Service.

Google Documentation - UI Service

Even though the UI Service is deprecated, there is a getUi() method of the spreadsheet class to add custom menus, which is NOT deprecated:

Spreadsheet Class - Get UI method

I mention this because it could be confusing because they both use the terminology UI.

The UI method returns a Ui return type.

You can add HTML to a UI Service, but you can't use a <button>, <input> or <script> tag in the HTML with the UI Service.

Here is a link to a shared Apps Script Web App file with an input form:

Shared File - Contact Form

Linebreaks (\n) only work if you put your string resource value in quotes like this:

<string name="sample_string">"some test line 1 \n some test line 2"</string>

It won't do linebreaks if you put it without quotes like this:

<string name="sample_string">some test line 1 \n some test line 2</string>

yes, it's that easy.

I'm assuming you are using jQuery or something similar. If you are using jQuery, then the following should work:

<html>
<head>
   <script src="jquery.js" type="text/javascript"></script>
</head>
<body>
   content
</body>
<script type="text/javascript">
   $("body").load(url);
</script>
</html>

In order to create a .jar file, you need to use jar instead of java:

jar cf myJar.jar myClass.class

Additionally, if you want to make it executable, you need to indicate an entry point (i.e., a class with public static void main(String[] args)) for your application. This is usually accomplished by creating a manifest file that contains the Main-Class header (e.g., Main-Class: myClass).

However, as Mark Peters pointed out, with JDK 6, you can use the e option to define the entry point:

jar cfe myJar.jar myClass myClass.class 

Finally, you can execute it:

java -jar myJar.jar

See also

• Creating a JAR File
• Setting an Application's Entry Point with the JAR Tool

With Joda-Time since version 2.0 you can use LocalDate.toDate().

Simply

// someDatetime is whatever java.util.Date you have.
Date someDay = new LocalDate(someDatetime).toDate();

If you want to print output of anything in Bash without end of line, you echo it with the -n switch.

If you have it in a variable already, then echo it with the trailing newline cropped:

$ testvar=$(wc -l < log.txt)
$ echo -n $testvar

Or you can do it in one line, instead:

$ echo -n $(wc -l < log.txt)

Try SQLDeveloper - there is a migration workbench there

You will need to save the Docker image as a tar file:

docker save -o <path for generated tar file> <image name>

Then copy your image to a new system with regular file transfer tools such as cp, scp or rsync(preferred for big files). After that you will have to load the image into Docker:

docker load -i <path to image tar file>

PS: You may need to sudo all commands.

EDIT: You should add filename (not just directory) with -o, for example:

docker save -o c:/myfile.tar centos:16

Since multi-window mode is available now, your app may not have statusbar on top.

Following solution handle all the cases automatically for you.

android:fitsSystemWindows="true"

or programatically

findViewById(R.id.your_root_view).setFitsSystemWindows(true);

you may also get root view by

findViewById(android.R.id.content).getRootView();
or
getWindow().getDecorView().findViewById(android.R.id.content)

For more details on getting root-view refer - https://stackoverflow.com/a/4488149/9640177

As everybody else has said, there is no difference. (As a sanity check I did some tests, but it was a waste of time, of course they work the same.)

But there are actually FOUR types of inequality operators: !=, ^=, <>, and ¬=. See this page in the Oracle SQL reference. On the website the fourth operator shows up as ÿ= but in the PDF it shows as ¬=. According to the documentation some of them are unavailable on some platforms. Which really means that ¬= almost never works.

Just out of curiosity, I'd really like to know what environment ¬= works on.

Use the Find method if item_manuf_id is a primary key:

var result = dtPs.Rows.Find("some value");

If you only want to know if the value is in there then use the Contains method.

if (dtPs.Rows.Contains("some value"))
{
  ...
}

Primary key restriction applies to Contains aswell.

LinearLayout YOUR_LinearLayout =(LinearLayout)findViewById(R.id.YOUR_LinearLayout)
    LinearLayout.LayoutParams param = new LinearLayout.LayoutParams(
                       /*width*/ ViewGroup.LayoutParams.MATCH_PARENT,
               /*height*/ 100,
               /*weight*/ 1.0f
                );
                YOUR_LinearLayout.setLayoutParams(param);

Look inside the implementation of the two methods to understand them deeply:

array1.equals(array2);

/**
 * Indicates whether some other object is "equal to" this one.
 * <p>
 * The {@code equals} method implements an equivalence relation
 * on non-null object references:
 * <ul>
 * <li>It is <i>reflexive</i>: for any non-null reference value
 *     {@code x}, {@code x.equals(x)} should return
 *     {@code true}.
 * <li>It is <i>symmetric</i>: for any non-null reference values
 *     {@code x} and {@code y}, {@code x.equals(y)}
 *     should return {@code true} if and only if
 *     {@code y.equals(x)} returns {@code true}.
 * <li>It is <i>transitive</i>: for any non-null reference values
 *     {@code x}, {@code y}, and {@code z}, if
 *     {@code x.equals(y)} returns {@code true} and
 *     {@code y.equals(z)} returns {@code true}, then
 *     {@code x.equals(z)} should return {@code true}.
 * <li>It is <i>consistent</i>: for any non-null reference values
 *     {@code x} and {@code y}, multiple invocations of
 *     {@code x.equals(y)} consistently return {@code true}
 *     or consistently return {@code false}, provided no
 *     information used in {@code equals} comparisons on the
 *     objects is modified.
 * <li>For any non-null reference value {@code x},
 *     {@code x.equals(null)} should return {@code false}.
 * </ul>
 * <p>
 * The {@code equals} method for class {@code Object} implements
 * the most discriminating possible equivalence relation on objects;
 * that is, for any non-null reference values {@code x} and
 * {@code y}, this method returns {@code true} if and only
 * if {@code x} and {@code y} refer to the same object
 * ({@code x == y} has the value {@code true}).
 * <p>
 * Note that it is generally necessary to override the {@code hashCode}
 * method whenever this method is overridden, so as to maintain the
 * general contract for the {@code hashCode} method, which states
 * that equal objects must have equal hash codes.
 *
 * @param   obj   the reference object with which to compare.
 * @return  {@code true} if this object is the same as the obj
 *          argument; {@code false} otherwise.
 * @see     #hashCode()
 * @see     java.util.HashMap
 */
public boolean equals(Object obj) {
    return (this == obj);
}

while:

Arrays.equals(array1, array2);

/**

Don't know if this helps anyone but I was struggling with this problem for awhile, none of the answers online helped me. For me the problem was I had different heights and widths set on the image in storyboard. I tried every solution on stack and it turns out it was something as simple as that. Once I set them both to 200 my circle profile image was perfect. This was code then in my VC.

profileImage2.layer.cornerRadius = profileImage2.frame.size.width/2
    profileImage2.clipsToBounds = true

Well if you are doing this in Asp.Net or have access to HttpContext.Current.Request I'd say these are easier and more general ways of getting them:

var scheme = Request.Url.Scheme; // will get http, https, etc.
var host = Request.Url.Host; // will get www.mywebsite.com
var port = Request.Url.Port; // will get the port
var path = Request.Url.AbsolutePath; // should get the /pages/page1.aspx part, can't remember if it only get pages/page1.aspx

I hope this helps. :)

The entire confusion is caused since Google chose non-intuivitive names instead of something as follows:

onCreateAndPrepareToDisplay()   [instead of onCreate() ]
onPrepareToDisplay()            [instead of onRestart() ]
onVisible()                     [instead of onStart() ]
onBeginInteraction()            [instead of onResume() ]
onPauseInteraction()            [instead of onPause() ]
onInvisible()                   [instead of onStop]
onDestroy()                     [no change] 

The Activity Diagram can be interpreted as:

There is a difference between what JSON.parse() and eval() will accept. Try eval on this:

var x = "{\"shoppingCartName\":\"shopping_cart:2000\"}"

eval(x)         //won't work
JSON.parse(x)   //does work

See this example.

Phone and cable companies maintain a model of their wiring topology, which in effect is a large network or graph. Recursion is one way to traverse this model when you want to find all parent or all child elements.

Since recursion is expensive from a processing and memory perspective, this step is commonly only performed when the topology is changed and the result is stored in a modified pre-ordered list format.

i don't know if this answer can be found on the links above, but i just run SQL management studio as Administrator and worked. Hope it helps

It turns out to get this application working under VBScript, I had to do two things.

1. Run RegAsm.exe to register the DLLs.
2. Run the C:\Windows\SysWOW64\cscript.exe to run my VBScript.

If these don't work, check out the other answer here about enabling 32-bit applications in IIS.

In Django 1.8, this is how I did mine.

from django.views.generic.base import RedirectView

url(r'^$', views.comingSoon, name='homepage'),
# whatever urls you might have in here
# make sure the 'catch-all' url is placed last
url(r'^.*$', RedirectView.as_view(pattern_name='homepage', permanent=False))

Instead of using url, you can use the pattern_name, which is a bit un-DRY, and will ensure you change your url, you don't have to change the redirect too.

It seems the docs/tool have been updated and you can now add the image tag to your script. This was successful for me.

Example:

version: '2'
services:

  baggins.api.rest:
    image: my.image.name:rc2
    build:
      context: ../..
      dockerfile: app/Docker/Dockerfile.release
    ports:
      ...

https://docs.docker.com/compose/compose-file/#build

As mentioned, but with a code sample:

foreach(var item in collection.ToArray())
    collection.Add(new Item...);

What's wrong:

The definition of "nonrecursivecountcells" has no parameter named grid. You need to pass the type AND variable name to the function. You only passed the type.

Note if you use the name grid for the parameter, that name has nothing to do with your main() declaration of grid. You could have used any other name as well.

***Also you can't pass arrays as values.

How to fix:

The easy way to fix this is to pass a pointer to an array to the function "nonrecursivecountcells".

int nonrecursivecountcells(color[ROW_SIZE][COL_SIZE], int, int);

better and type safe ->

int nonrecursivecountcells(color (&grid)[ROW_SIZE][COL_SIZE], int, int);

About scope:

A variable created on the stack comes out of scope when the block it is declared in is terminated. A block is anything within an opening and matching closing brace. For example an if() { }, function() { }, while() {}, ...

Note I said variable and not data. For example you can allocate memory on the heap and that data will still remain valid even outside of the scope. But the variable that originally pointed to it would still come out of scope.

The ACTION_SEND will only give you options for sending using GMail, YahooMail... etc(Any application installed on your phone, that can perform ACTION_SEND). If you want to share on Facebook or Twitter you will need to place custom buttons for each and use their own SDK such as Facebook SDK or Twitter4J .

you can use:

$('body').ready(function(){
   $(document).on('change', '#elemID', function(){
      // do something
   });
});

It works with me.

If your Local branch and remote branch is the same name then you can just do it:

git push origin branchName

When your local and remote branch name is different then you can just do it:

git push origin localBranchName:remoteBranchName

var someString = "(/n{})+++(/n{})---(/n{})$$$";_x000D_
var toRemove = "(/n{})"; // should find & remove last occurrence _x000D_
_x000D_
function removeLast(s, r){_x000D_
  s = s.split(r)_x000D_
  return s.slice(0,-1).join(r) + s.pop()_x000D_
}_x000D_
_x000D_
console.log(_x000D_
  removeLast(someString, toRemove)_x000D_
)

Breakdown:

s = s.split(toRemove)         // ["", "+++", "---", "$$$"]

s.slice(0,-1)                 //  ["", "+++", "---"]   

s.slice(0,-1).join(toRemove)  // "})()+++})()---"

s.pop()                       //  "$$$"   

Another way of doing this is using nested IF statements. Suppose you have companies table and you want to count number of records in it. A sample query would be something like this

SELECT IF(
      count(*) > 15,
      'good',
      IF(
          count(*) > 10,
          'average',
          'poor'
        ) 
      ) as data_count 
      FROM companies

Here second IF condition works when the first IF condition fails. So Sample Syntax of the IF statement would be IF ( CONDITION, THEN, ELSE). Hope it helps someone.

HEX_TO_BINARY_CONVERSION_TABLE = { '0': '0000',

                              '1': '0001',

                              '2': '0010',

                              '3': '0011',

This is another Python3 variant of airmind's example. I wanted some specific features I didn't see in the other examples

• use colors for the terminal but do not write non-printable characters in the file handlers (I defined 2 formatters for this)
• ability to override the color for a specific log message
• configure the logger from a file (yaml in this case)

Notes: I used colorama but you could modify this so it is not required. Also for my testing I was just running python file so my class is in module __main__ You would have to change (): __main__.ColoredFormatter to whatever your module is.

pip install colorama pyyaml

output:

When I tried to access the result from

Object.keys(a).forEach(function (key){ console.log(a[key]); });

it was plain text result with no key-value pairs Here is an example

var fruits = {
    apple: "fruits/apple.png",
    banana: "fruits/banana.png",
    watermelon: "watermelon.jpg",
    grapes: "grapes.png",
    orange: "orange.jpg"
}

Now i want to get all links in a separated array , but with this code

    function linksOfPics(obJect){
Object.keys(obJect).forEach(function(x){
    console.log('\"'+obJect[x]+'\"');
});
}

the result of :

linksOfPics(fruits)



"fruits/apple.png"
 "fruits/banana.png"
 "watermelon.jpg"
 "grapes.png"
 "orange.jpg"
undefined

I figured out this one which solves what I'm looking for

  console.log(Object.values(fruits));
["fruits/apple.png", "fruits/banana.png", "watermelon.jpg", "grapes.png", "orange.jpg"]

I had the same problem. Here's what I did:

1. I downloaded pywin32 Wheel file from here, then

2. I uninstalled the pywin32 module. To uninstall execute the following command in Command Prompt.

   pip uninstall pywin32

3. Then, I reinstalled pywin32. To install it, open the Command Prompt in the same directory where the pywin32 wheel file lies. Then execute the following command.

   pip install <Name of the wheel file with extension> Wheel file will be like: piwin32-XXX-cpXX-none-win32.whl

It solvs the problem for me. You may also like to give it a try. Hope it work for you as well.

window.location.protocol === 'http:' && (location.href = location.href.replace(/^http:/, 'https:'));

In Java 8, you don't have to use isDebugEnabled() to improve the performance.

https://logging.apache.org/log4j/2.0/manual/api.html#Java_8_lambda_support_for_lazy_logging

import java.util.logging.Logger;
...
Logger.getLogger("hello").info(() -> "Hello " + name);

From within less (in Linux):

 g and the line number to go forward

 G and the line number to go backwards

Used alone, g and G will take you to the first and last line in a file respectively; used with a number they are both equivalent.

An example; you want to go to line 320123 of a file,

press 'g' and after the colon type in the number 320123

Additionally you can type '-N' inside less to activate / deactivate the line numbers. You can as a matter of fact pass any command line switches from inside the program, such as -j or -N.

NOTE: You can provide the line number in the command line to start less (less +number -N) which will be much faster than doing it from inside the program:

less +12345 -N /var/log/hugelogfile

This will open a file displaying the line numbers and starting at line 12345

Source: man 1 less and built-in help in less (less 418)

Arrays are not changeable after initialization. You have to give it a value, and that value is what that array length stays. You can create multiple arrays to contain certain parts of player information like their hand and such, and then create an arrayList to sort of shepherd those arrays.

Another point of contention I see, and I may be wrong about this, is the fact that your private Player[] InitializePlayers() is static where the class is now non-static. So:

private Player[] InitializePlayers(int playerCount)
{
 ...
}

My last point would be that you should probably have playerCount declared outside of the method that is going to change it so that the value that is set to it becomes the new value as well and it is not just tossed away at the end of the method's "scope."

Hope this helps

How about this...?

TextReader tr = new StringReader("<Root>Content</Root>");
XDocument doc = XDocument.Load(tr);
Console.WriteLine(doc);

This was taken from the MSDN docs for XDocument.Load, found here...

It is possible to connect to the database without specifying a password. Once you've done that you can then reset the passwords. I'm assuming that you've installed the database on your machine; if not you'll first need to connect to the machine the database is running on.

1. Ensure your user account is a member of the dba group. How you do this depends on what OS you are running.

2. Enter sqlplus / as sysdba in a Command Prompt/shell/Terminal window as appropriate. This should log you in to the database as SYS.

3. Once you're logged in, you can then enter

   alter user SYS identified by "newpassword";
   

   to reset the SYS password, and similarly for SYSTEM.

(Note: I haven't tried any of this on Oracle 12c; I'm assuming they haven't changed things since Oracle 11g.)

You need either of the following depending on the type of the container of T elements you pass to the builder (Collection<T> or T[]):

• In case of an existing Collection<T> YOUR_COLLECTION:

Collections.unmodifiableList(new ArrayList<>(YOUR_COLLECTION));

• In case of an existing T[] YOUR_ARRAY:

Arrays.asList(YOUR_ARRAY);

Simple as that

I'd suggest the question you should be asking is how to inject services into controllers. Fat services with skinny controllers is a good rule of thumb, aka just use controllers to glue your service/factory (with the business logic) into your views.

Controllers get garbage collected on route changes, so for example, if you use controllers to hold business logic that renders a value, your going to lose state on two pages if the app user clicks the browser back button.

var app = angular.module("testApp", ['']);

app.factory('methodFactory', function () {
    return { myMethod: function () {
            console.log("methodFactory - myMethod");
    };
};

app.controller('TestCtrl1', ['$scope', 'methodFactory', function ($scope,methodFactory) {  //Comma was missing here.Now it is corrected.
    $scope.mymethod1 = methodFactory.myMethod();
}]);

app.controller('TestCtrl2', ['$scope', 'methodFactory', function ($scope, methodFactory) {
    $scope.mymethod2 = methodFactory.myMethod();
}]);

Here is a working demo of factory injected into two controllers

Also, I'd suggest having a read of this tutorial on services/factories.

I was facing this issue in Grafana and all I had to do was go to the config file and change allow_embedding to true and restart the server :)

Heres some code in c to convert rgb to grayscale. The real weighting used for rgb to grayscale conversion is 0.3R+0.6G+0.11B. these weights arent absolutely critical so you can play with them. I have made them 0.25R+ 0.5G+0.25B. It produces a slightly darker image.

NOTE: The following code assumes xRGB 32bit pixel format

unsigned int *pntrBWImage=(unsigned int*)..data pointer..;  //assumes 4*width*height bytes with 32 bits i.e. 4 bytes per pixel
unsigned int fourBytes;
        unsigned char r,g,b;
        for (int index=0;index<width*height;index++)
        {
            fourBytes=pntrBWImage[index];//caches 4 bytes at a time
            r=(fourBytes>>16);
            g=(fourBytes>>8);
            b=fourBytes;

            I_Out[index] = (r >>2)+ (g>>1) + (b>>2); //This runs in 0.00065s on my pc and produces slightly darker results
            //I_Out[index]=((unsigned int)(r+g+b))/3;     //This runs in 0.0011s on my pc and produces a pure average
        }

I tried doing sudo pip uninstall numpy instead, because the rm didn't work at first.

Hopefully that helps.

Uninstalling then to install it again.

Simple Override onBackPressed Method:

    @Override
    public void onBackPressed() {
            super.onBackPressed();
            this.finish();
    }

It's not an error. Javascript will gladly convert a number to a string when a string is expected (for example parseInt(42)), but in this case there is nothing that expect the number to be a string.

Here's a makeLowerCase function. :)

function makeLowerCase(value) {
  return value.toString().toLowerCase();
}

While this is probably an awful idea, it is along the same lines as rlotun's answer but it'll return the correct result more often.

import inspect
def getVarName(getvar):
  frame = inspect.currentframe()
  callerLocals = frame.f_back.f_locals
  for k, v in list(callerLocals.items()):
    if v is getvar():
      callerLocals.pop(k)
      try:
        getvar()
        callerLocals[k] = v
      except NameError:
        callerLocals[k] = v
        del frame
        return k
  del frame

You call it like this:

bar = True
foo = False
bean = False
fooName = getVarName(lambda: foo)
print(fooName) # prints "foo"
