Programs & Examples On #Pagefile

I also faced a similar issue. The reason was that I had the changes done in the .aspx page but not the designer page and hence I got the mentioned error. When the reference was created in the designer page I was able to build the solution.

You can try onload event. It raised when all scripts has been loaded :

window.onload = function () {
   //jquery ready for use here
}

But keep in mind, that you may override others scripts where window.onload using.

I had the same issue , i was foreach looping over my object and adding the result into a Dictionary<string, string> and i had a `Duplicate in the key from the database

 foreach (var item in myObject)
        {
            myDictionary.Add(Convert.ToString(item.x), 
                                   item.y);

        }

item.x had a duplicate value

This is because ASP.NET it changing the Id of your textbox, if you run your page, and do a view source, you will see the text box id is something like

ctl00_ContentColumn_txt_model_code

There are a few ways round this:

Use the actual control name:

var TestVar = document.getElementById('ctl00_ContentColumn_txt_model_code').value;

use the ClientID property within ASP script tags

document.getElementById('<%= txt_model_code.ClientID %>').value;

Or if you are running .NET 4 you can use the new ClientIdMode property, see this link for more details.

http://weblogs.asp.net/scottgu/archive/2010/03/30/cleaner-html-markup-with-asp-net-4-web-forms-client-ids-vs-2010-and-net-4-0-series.aspx1

Look for this:

ANY page in your project that has a missing, or different Namespace...

If you have ANY page in your project with <NO Namespace> , OR a

DIFFERENT Namespace than Default.aspx, you will get this

"Cannot load Default.aspx", or this: "Default.aspx does not belong here".

ALSO: If you have a Redirect to a page in your Solution/Project and the page which is to be Redirected To has a bad namespace -- you may not get a compiler error, until you try and run. If the Redirect is removed or commented-out, the error goes away...

BTW -- What the hell do these error messages mean? Is this MS.Access, with the "misdirection" -- ??

I wanted to update or reset a value if it didn't quite validate, and ran into this problem.

The easy answer, ModelState.Remove, is.. problematic.. because if you are using helpers you don't really know the name (unless you stick by the naming convention). Unless perhaps you create a function that both your custom helper and your controller can use to get a name.

This feature should have been implemented as an option on the helper, where by default is does not do this, but if you wanted the unaccepted input to redisplay you could just say so.

But at least I understand the issue now ;).

I encountered this error after editing a web part (.aspx) page in SharePoint Designer 2013. When I looked at the code in SPD, an H1 element near the top of the page was highlighted yellow. Hovering over that indicated that SharePoint:AjaxDelta was not closed before the H1. Adding the </SharePoint:AjaxDelta> fixed it.

Weird because it appeared SPD introduced the error after I was working on listview web parts or a page viewer web part elsewhere on the page.

Yes, it is possible using SpannedString. If you are using Kotlin, it becomes even easier to do by using core-ktx, as it provides a domain-specific-language (DSL) for doing this:

    val string: SpannedString = buildSpannedString {
        bold {
            append("1111")
        }
        append("Devansh")     
    }

More options provided by it are:

append("Hello There")
bold {
    append("bold")
    italic {
        append("bold and italic")
        underline {
            append("then some text with underline")
        }
    }
}

At last, you can just to:

textView.text = string

First find the difference between the start point and the end point (here, this is more of a directed line segment, not a "line", since lines extend infinitely and don't start at a particular point).

deltaY = P2_y - P1_y
deltaX = P2_x - P1_x

Then calculate the angle (which runs from the positive X axis at P1 to the positive Y axis at P1).

angleInDegrees = arctan(deltaY / deltaX) * 180 / PI

But arctan may not be ideal, because dividing the differences this way will erase the distinction needed to distinguish which quadrant the angle is in (see below). Use the following instead if your language includes an atan2 function:

angleInDegrees = atan2(deltaY, deltaX) * 180 / PI

EDIT (Feb. 22, 2017): In general, however, calling atan2(deltaY,deltaX) just to get the proper angle for cos and sin may be inelegant. In those cases, you can often do the following instead:

1. Treat (deltaX, deltaY) as a vector.
2. Normalize that vector to a unit vector. To do so, divide deltaX and deltaY by the vector's length (sqrt(deltaX*deltaX+deltaY*deltaY)), unless the length is 0.
3. After that, deltaX will now be the cosine of the angle between the vector and the horizontal axis (in the direction from the positive X to the positive Y axis at P1).
4. And deltaY will now be the sine of that angle.
5. If the vector's length is 0, it won't have an angle between it and the horizontal axis (so it won't have a meaningful sine and cosine).

EDIT (Feb. 28, 2017): Even without normalizing (deltaX, deltaY):

• The sign of deltaX will tell you whether the cosine described in step 3 is positive or negative.
• The sign of deltaY will tell you whether the sine described in step 4 is positive or negative.
• The signs of deltaX and deltaY will tell you which quadrant the angle is in, in relation to the positive X axis at P1:
  • +deltaX, +deltaY: 0 to 90 degrees.
  • -deltaX, +deltaY: 90 to 180 degrees.
  • -deltaX, -deltaY: 180 to 270 degrees (-180 to -90 degrees).
  • +deltaX, -deltaY: 270 to 360 degrees (-90 to 0 degrees).

An implementation in Python using radians (provided on July 19, 2015 by Eric Leschinski, who edited my answer):

from math import *
def angle_trunc(a):
    while a < 0.0:
        a += pi * 2
    return a

def getAngleBetweenPoints(x_orig, y_orig, x_landmark, y_landmark):
    deltaY = y_landmark - y_orig
    deltaX = x_landmark - x_orig
    return angle_trunc(atan2(deltaY, deltaX))

angle = getAngleBetweenPoints(5, 2, 1,4)
assert angle >= 0, "angle must be >= 0"
angle = getAngleBetweenPoints(1, 1, 2, 1)
assert angle == 0, "expecting angle to be 0"
angle = getAngleBetweenPoints(2, 1, 1, 1)
assert abs(pi - angle) <= 0.01, "expecting angle to be pi, it is: " + str(angle)
angle = getAngleBetweenPoints(2, 1, 2, 3)
assert abs(angle - pi/2) <= 0.01, "expecting angle to be pi/2, it is: " + str(angle)
angle = getAngleBetweenPoints(2, 1, 2, 0)
assert abs(angle - (pi+pi/2)) <= 0.01, "expecting angle to be pi+pi/2, it is: " + str(angle)
angle = getAngleBetweenPoints(1, 1, 2, 2)
assert abs(angle - (pi/4)) <= 0.01, "expecting angle to be pi/4, it is: " + str(angle)
angle = getAngleBetweenPoints(-1, -1, -2, -2)
assert abs(angle - (pi+pi/4)) <= 0.01, "expecting angle to be pi+pi/4, it is: " + str(angle)
angle = getAngleBetweenPoints(-1, -1, -1, 2)
assert abs(angle - (pi/2)) <= 0.01, "expecting angle to be pi/2, it is: " + str(angle)

All tests pass. See https://en.wikipedia.org/wiki/Unit_circle

Named parameters are not supported by JPA in native queries, only for JPQL. You must use positional parameters.

Named parameters follow the rules for identifiers defined in Section 4.4.1. The use of named parameters applies to the Java Persistence query language, and is not defined for native queries. Only positional parameter binding may be portably used for native queries.

So, use this

Query q = em.createNativeQuery("SELECT count(*) FROM mytable where username = ?1");
q.setParameter(1, "test");

While JPA specification doesn't support named parameters in native queries, some JPA implementations (like Hibernate) may support it

Native SQL queries support positional as well as named parameters

However, this couples your application to specific JPA implementation, and thus makes it unportable.

You can use Array.prototype.find function in javascript. Array find MDN.

So to find string in array of string, the code becomes very simple. Plus as browser implementation, it will provide good performance.

Ex.

var strs = ['abc', 'def', 'ghi', 'jkl', 'mno'];
var value = 'abc';
strs.find(
    function(str) {
        return str == value;
    }
);

or using lambda expression it will become much shorter

var strs = ['abc', 'def', 'ghi', 'jkl', 'mno'];
var value = 'abc';
strs.find((str) => str === value);

As per keras tutorial, you can simply use the same tf.device scope as in regular tensorflow:

with tf.device('/gpu:0'):
    x = tf.placeholder(tf.float32, shape=(None, 20, 64))
    y = LSTM(32)(x)  # all ops in the LSTM layer will live on GPU:0

with tf.device('/cpu:0'):
    x = tf.placeholder(tf.float32, shape=(None, 20, 64))
    y = LSTM(32)(x)  # all ops in the LSTM layer will live on CPU:0

You can use ''; to declaring NULL variable in Javascript

I find that these 2 steps work for me all the time:

1. Confirm (else add) the parent folder of the module to the PYTHONPATH.
2. Add FULL name of the module to forced builtins.

The things to note here:

• Some popular modules install with some parent and child pair having the same name. In these cases you also have to add that parent to PYTHONPATH, in addition to its grandparent folder, which you already confirmed/added for everything else.

• Use (for example) "google.appengine.api.memcache" when adding to forced builtins, NOT "memcache" only, where "google" in this example, is an immediate child of a folder defined in PYTHONPATH.

I found this answer on another site:

Disable scroll:

$( ".popup").live({
    popupbeforeposition: function(event, ui) {
    $("body").on("touchmove", false);
}
});

After close popup release scroll:

$( ".popup" ).live({
    popupafterclose: function(event, ui) {
    $("body").unbind("touchmove");
}
});

The general rule seems to be that browsers encode form responses according to the content-type of the page the form was served from. This is a guess that if the server sends us "text/xml; charset=iso-8859-1", then they expect responses back in the same format.

If you're just entering a URL in the URL bar, then the browser doesn't have a base page to work on and therefore just has to guess. So in this case it seems to be doing utf-8 all the time (since both your inputs produced three-octet form values).

The sad truth is that AFAIK there's no standard for what character set the values in a query string, or indeed any characters in the URL, should be interpreted as. At least in the case of values in the query string, there's no reason to suppose that they necessarily do correspond to characters.

It's a known problem that you have to tell your server framework which character set you expect the query string to be encoded as--- for instance, in Tomcat, you have to call request.setEncoding() (or some similar method) before you call any of the request.getParameter() methods. The dearth of documentation on this subject probably reflects the lack of awareness of the problem amongst many developers. (I regularly ask Java interviewees what the difference between a Reader and an InputStream is, and regularly get blank looks)

You're thinking too DOM, it's a hard as hell habit to break. Vue recommends you approach it data first.

It's kind of hard to tell in your exact situation but I'd probably use a v-for and make an array of finds to push to as I need more.

Here's how I'd set up my instance:

new Vue({
  el: '#app',
  data: {
    finds: []
  },
  methods: {
    addFind: function () {
      this.finds.push({ value: '' });
    }
  }
});

And here's how I'd set up my template:

<div id="app">
  <h1>Finds</h1>
  <div v-for="(find, index) in finds">
    <input v-model="find.value" :key="index">
  </div>
  <button @click="addFind">
    New Find
  </button>
</div>

Although, I'd try to use something besides an index for the key.

Here's a demo of the above: https://jsfiddle.net/crswll/24txy506/9/

You should try not open the file with a folder-explorer method (i.e. file://), but open that file from http:// (i.e. http://yoursite.com/ from http://localhost/)

Make sure your body has a height, f.ex:

body { 
    background: url(/img/debut_dark.png) repeat;
    min-height: 100%;
}

I have found this better way , no need to remove data , just call the source of the remote content each time

$(document).ready(function() {
    $('.class').click(function() {
        var id = this.id;
        //alert(id);checking that have correct id
        $("#iframe").attr("src","url?id=" + id);
        $('#Modal').modal({ 
            show: true 
        });
    });
});

You need to type it without the word image.

background: url('/image/btn.png') no-repeat;

Tested both ways and this one works.

Example:

<html>
    <head>
        <style type="text/css">
            .button{
                background: url(/image/btn.png) no-repeat;
                cursor:pointer;
                border: none;
            }
        </style>
    </head>
    <body>
        <input type="button" name="button" value="Search" onclick="showUser()" class="button"/>
        <input type="image" name="button" value="Search" onclick="showUser()" class="button"/>
        <input type="submit" name="button" value="Search" onclick="showUser()" class="button"/>
    </body>
</html>

try to add ojdbc6.jar through the server lib "C:\apache-tomcat-7.0.47\lib",

Then restart the server in eclipse.

You could use the CSS calc parameter to calculate the height dynamically like so:

.dynamic-height {_x000D_
   color: #000;_x000D_
   font-size: 12px;_x000D_
   margin-top: calc(100% - 10px);_x000D_
   text-align: left;_x000D_
}

<div class='dynamic-height'>_x000D_
    <p>Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Aenean commodo ligula eget dolor. Aenean massa. Cum sociis natoque penatibus et magnis dis parturient montes, nascetur ridiculus mus. Donec quam felis, ultricies nec, pellentesque eu, pretium quis, sem.</p>_x000D_
</div>

Set the same date and time in your android phone and in your laptop.

I had a similar problem of logs not showing, and when I set the correct date in the phone I started seeing the logs (I restarted the phone and the hour was completely wrong!).

you can insert using loop if you want to insert some random values.

BEGIN 
    FOR x IN 1 .. 1000 LOOP
         INSERT INTO MULTI_INSERT_DEMO (ID, NAME)
         SELECT x, 'anyName' FROM dual;
    END LOOP;
END;

Since Java 11 you can do:

FileWriter fw = new FileWriter("filename.txt", Charset.forName("utf-8"));

I had this issue after installing dotnetframework4.5.
Open path below:
"C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\bin" ( in 64 bits machine)
or
"C:\Program Files\Microsoft Visual Studio 10.0\VC\bin" (in 32 bits machine)
In this path find file cvtres.exe and rename it to cvtres1.exe then compile your project again.

I have removed it from my references.Then run this in Package Manager Console

Install-Package WebMatrix.Data

Finally add WebMatrix.WebData assembly to references,and rebuild project.It works for me.I hope it solves your problem too.

Look at the methods in the java.io.File class:

File file = new File("yourfileName");
String path = file.getAbsolutePath();

Put the command

yum install php-gd

and restart the server (httpd, nginx, etc)

service httpd restart

In my case i was using Ubuntu. Where the was two directories one was /android-sdks and /android-sdk-linux. I used the second one it works for me :)

I'll rename the function take_closest to conform with PEP8 naming conventions.

If you mean quick-to-execute as opposed to quick-to-write, min should not be your weapon of choice, except in one very narrow use case. The min solution needs to examine every number in the list and do a calculation for each number. Using bisect.bisect_left instead is almost always faster.

The "almost" comes from the fact that bisect_left requires the list to be sorted to work. Hopefully, your use case is such that you can sort the list once and then leave it alone. Even if not, as long as you don't need to sort before every time you call take_closest, the bisect module will likely come out on top. If you're in doubt, try both and look at the real-world difference.

from bisect import bisect_left

def take_closest(myList, myNumber):
    """
    Assumes myList is sorted. Returns closest value to myNumber.

    If two numbers are equally close, return the smallest number.
    """
    pos = bisect_left(myList, myNumber)
    if pos == 0:
        return myList[0]
    if pos == len(myList):
        return myList[-1]
    before = myList[pos - 1]
    after = myList[pos]
    if after - myNumber < myNumber - before:
       return after
    else:
       return before

Bisect works by repeatedly halving a list and finding out which half myNumber has to be in by looking at the middle value. This means it has a running time of O(log n) as opposed to the O(n) running time of the highest voted answer. If we compare the two methods and supply both with a sorted myList, these are the results:

$ python -m timeit -s "
from closest import take_closest
from random import randint
a = range(-1000, 1000, 10)" "take_closest(a, randint(-1100, 1100))"

100000 loops, best of 3: 2.22 usec per loop

$ python -m timeit -s "
from closest import with_min
from random import randint
a = range(-1000, 1000, 10)" "with_min(a, randint(-1100, 1100))"

10000 loops, best of 3: 43.9 usec per loop

So in this particular test, bisect is almost 20 times faster. For longer lists, the difference will be greater.

What if we level the playing field by removing the precondition that myList must be sorted? Let's say we sort a copy of the list every time take_closest is called, while leaving the min solution unaltered. Using the 200-item list in the above test, the bisect solution is still the fastest, though only by about 30%.

This is a strange result, considering that the sorting step is O(n log(n))! The only reason min is still losing is that the sorting is done in highly optimalized c code, while min has to plod along calling a lambda function for every item. As myList grows in size, the min solution will eventually be faster. Note that we had to stack everything in its favour for the min solution to win.

To make the answer more re-usable for things other than just the datepicker change function you can create a prototype to handle this for you.

// safety check to see if the prototype name is already defined
Function.prototype.method = function (name, func) {
    if (!this.prototype[name]) {
        this.prototype[name] = func;
        return this;
    }
};
Date.method('inPast', function () {
    return this < new Date($.now());// the $.now() requires jQuery
});

// including this prototype as using in example
Date.method('addDays', function (days) {
    var date = new Date(this);
    date.setDate(date.getDate() + (days));    
    return date;
});

If you dont like the safety check you can use the conventional way to define prototypes:

Date.prototype.inPast = function(){
    return this < new Date($.now());// the $.now() requires jQuery
}

Example Usage

var dt = new Date($.now());
var yesterday = dt.addDays(-1);
var tomorrow = dt.addDays(1);
console.log('Yesterday: ' + yesterday.inPast());
console.log('Tomorrow: ' + tomorrow.inPast());

Check wifi type in connectivity manager:

   //check network connection
    ConnectivityManager cm = (ConnectivityManager) this.getSystemService(Context.CONNECTIVITY_SERVICE);
    NetworkInfo activeNetwork = cm.getActiveNetworkInfo();
    boolean hasNetworkConnection = activeNetwork != null && activeNetwork.isConnectedOrConnecting();
    System.out.println("Connection ? : " + hasNetworkConnection);
    //check wifi
    boolean hasWifiConnection = activeNetwork.getType() == ConnectivityManager.TYPE_WIFI;
    System.out.println("Wifi ? : " + hasWifiConnection);

Android Documentation describes 'TYPE_WIFI' as 'A WIFI data connection. Devices may support more than one.'

This error was generated for me by having an incorrectly formatted NLog.config file.

This can be done in in 3 lines of code:

// grab the window frame and adjust it for orientation
UIView *rootView = [[[UIApplication sharedApplication] keyWindow] 
                                   rootViewController].view;
CGRect originalFrame = [[UIScreen mainScreen] bounds];
CGRect adjustedFrame = [rootView convertRect:originalFrame fromView:nil];

If you want to save the image and you know its URL you can do this:

try(InputStream in = new URL("http://example.com/image.jpg").openStream()){
    Files.copy(in, Paths.get("C:/File/To/Save/To/image.jpg"));
}

You will also need to handle the IOExceptions which may be thrown.

I think you have to use ::-wekbit-scrollbar for all the scrollbars, and you can use:

    .mydiv::-webkit-scrollbar {

I'm facing a similar problem. I'm using Query by Example and I want to sort the results by a custom field. In SQL I would do something like:

select pageNo, abs(pageNo - 434) as diff
from relA
where year = 2009
order by diff

It works fine without the order-by-clause. What I got is

Criteria crit = getSession().createCriteria(Entity.class);
crit.add(exampleObject);
ProjectionList pl = Projections.projectionList();
pl.add( Projections.property("id") );
pl.add(Projections.sqlProjection("abs(`pageNo`-"+pageNo+") as diff", new String[] {"diff"}, types ));
crit.setProjection(pl);

But when I add

crit.addOrder(Order.asc("diff"));

I get a org.hibernate.QueryException: could not resolve property: diff exception. Workaround with this does not work either.

PS: as I could not find any elaborate documentation on the use of QBE for Hibernate, all the stuff above is mainly trial-and-error approach

Booleans are nothing but integers only, they are just type casted values like...

typedef signed char     BOOL; 

#define YES (BOOL)1
#define NO (BOOL)0

BOOL value = YES; 
NSLog(@"Bool value: %d",value);

If output is 1,YES otherwise NO

Here how I solved it using Cookies:

First of all, inside the website main script:

var browserWindowSize = getCookie("_browserWindowSize");
var newSize = $(window).width() + "," + $(window).height();
var reloadForCookieRefresh = false;

if (browserWindowSize == undefined || browserWindowSize == null || newSize != browserWindowSize) {
    setCookie("_browserWindowSize", newSize, 30);
    reloadForCookieRefresh = true;
}

if (reloadForCookieRefresh)
    window.location.reload();

function setCookie(name, value, days) {
    var expires = "";
    if (days) {
        var date = new Date();
        date.setTime(date.getTime() + (days * 24 * 60 * 60 * 1000));
        expires = "; expires=" + date.toUTCString();
    }
    document.cookie = name + "=" + (value || "") + expires + "; path=/";
}

function getCookie(name) {
    var nameEQ = name + "=";
    var ca = document.cookie.split(';');
    for (var i = 0; i < ca.length; i++) {
        var c = ca[i];
        while (c.charAt(0) == ' ') c = c.substring(1, c.length);
        if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length, c.length);
    }
    return null;
}

And inside MVC action filter:

public class SetCurrentRequestDataFilter : ActionFilterAttribute
{
    public override void OnActionExecuting(ActionExecutingContext filterContext)
    {
        // currentRequestService is registered per web request using IoC
        var currentRequestService = iocResolver.Resolve<ICurrentRequestService>();

        if (filterContext.HttpContext.Request.Cookies.AllKeys.Contains("_browserWindowSize"))
        {
            var browserWindowSize = filterContext.HttpContext.Request.Cookies.Get("_browserWindowSize").Value.Split(',');
            currentRequestService.browserWindowWidth = int.Parse(browserWindowSize[0]);
            currentRequestService.browserWindowHeight = int.Parse(browserWindowSize[1]);
        }

    }
}

Yes there is a way to do it.

First declare a class.

//anyfile.ts
export class Custom
{
  name: string, 
  empoloyeeID: number
}

Then in your component import the class

import {Custom} from '../path/to/anyfile.ts'
.....
export class FormComponent implements OnInit {
 name: string;
 empoloyeeID : number;
 empList: Array<Custom> = [];
 constructor() {

 }

 ngOnInit() {
 }
 onEmpCreate(){
   //console.log(this.name,this.empoloyeeID);
   let customObj = new Custom();
   customObj.name = "something";
   customObj.employeeId = 12; 
   this.empList.push(customObj);
   this.name ="";
   this.empoloyeeID = 0; 
 }
}

Another way would be to interfaces read the documentation once - https://www.typescriptlang.org/docs/handbook/interfaces.html

Also checkout this question, it is very interesting - When to use Interface and Model in TypeScript / Angular2

You use:

yourcommand  > /dev/null 2>&1

If it should run in the Background add an &

yourcommand > /dev/null 2>&1 &

>/dev/null 2>&1 means redirect stdout to /dev/null AND stderr to the place where stdout points at that time

If you want stderr to occur on console and only stdout going to /dev/null you can use:

yourcommand 2>&1 > /dev/null

In this case stderr is redirected to stdout (e.g. your console) and afterwards the original stdout is redirected to /dev/null

If the program should not terminate you can use:

nohup yourcommand &

Without any parameter all output lands in nohup.out

none of the answers worked for me in 2017 with capybara 2.7. I got "ArgumentError: wrong number of arguments (given 2, expected 0)"

But this did:

find('#organizationSelect').all(:css, 'option').find { |o| o.value == 'option_name_here' }.select_option

It is possible to reference an intellij 'Path Variable' in an intellij 'Run Configuration'.

In 'Path Variables' create a variable for example ANALYTICS_VERSION.

In a 'Run Configuration' under 'Environment Variables' add for example the following:

ANALYTICS_LOAD_LOCATION=$MAVEN_REPOSITORY$\com\my\company\analytics\$ANALYTICS_VERSION$\bin

To answer the original question you would need to add an APP_HOME environment variable to your run configuration which references the path variable:

APP_HOME=$APP_HOME$

A possible workaround would be to use the multi-cursor. select the >< part of your example use Ctrl+Shift+L or select all occurrences. Then use the arrow keys to move all the cursors between the tags and press enter to insert a newline everywhere.

This won't work in all situations.

You can also use Ctrl+D for select next match, which adds the next match to the selection and adds a cursor. And use Ctrl+K Ctrl+D to skip a selection.

I got the same problem and it is not the solution that you told. So I changed the "from datetime import datetime" to "import datetime". After that with the help of "datetime.datetime" I can get the whole modules correctly. I guess this is the correct answer to that question.

open command prompt and run the following commands (assuming python 2.7):

cd c:\Python27\scripts\
pip install opencv-python

the above works for me for python 2.7 on windows 10 64 bit

• The code 302 indicates a temporary redirection.
• One of the most notable features that differentiate it from a 301 redirect is that, in the case of 302 redirects, the strength of the SEO is not transferred to a new URL.
• This is because this redirection has been designed to be used when there is a need to redirect content to a page that will not be the definitive one. Thus, once the redirection is eliminated, the original page will not have lost its positioning in the Google search engine.

EXAMPLE:- Although it is not very common that we find ourselves in need of a 302 redirect, this option can be very useful in some cases. These are the most frequent cases:

• When we realize that there is some inappropriate content on a page. While we solve the problem, we can redirect the user to another page that may be of interest.
• In the event that an attack on our website requires the restoration of any of the pages, this redirect can help us minimize the incidence.

A redirect 302 is a code that tells visitors of a specific URL that the page has been moved temporarily, directing them directly to the new location.

• In other words, redirect 302 is activated when Google robots or other search engines request to load a specific page. At that moment, thanks to this redirection, the server returns an automatic response indicating a new URL.

• In this way errors and annoyances are avoided both to search engines and users, guaranteeing smooth navigation.

This is working as intended, notification messages are delivered to your onMessageReceived callback only when your app is in the foreground. If your app is in the background or closed then a notification message is shown in the notification center, and any data from that message is passed to the intent that is launched as a result of the user tapping on the notification.

You can specify a click_action to indicate the intent that should be launched when the notification is tapped by the user. The main activity is used if no click_action is specified.

When the intent is launched you can use the

getIntent().getExtras();

to retrieve a Set that would include any data sent along with the notification message.

For more on notification message see docs.

This is simple operation no need to use any external library.

You can use this class instead :) (handles even lists , nested lists and json)

public class Utility {

    public static Map<String, Object> jsonToMap(Object json) throws JSONException {

        if(json instanceof JSONObject)
            return _jsonToMap_((JSONObject)json) ;

        else if (json instanceof String)
        {
            JSONObject jsonObject = new JSONObject((String)json) ;
            return _jsonToMap_(jsonObject) ;
        }
        return null ;
    }


   private static Map<String, Object> _jsonToMap_(JSONObject json) throws JSONException {
        Map<String, Object> retMap = new HashMap<String, Object>();

        if(json != JSONObject.NULL) {
            retMap = toMap(json);
        }
        return retMap;
    }


    private static Map<String, Object> toMap(JSONObject object) throws JSONException {
        Map<String, Object> map = new HashMap<String, Object>();

        Iterator<String> keysItr = object.keys();
        while(keysItr.hasNext()) {
            String key = keysItr.next();
            Object value = object.get(key);

            if(value instanceof JSONArray) {
                value = toList((JSONArray) value);
            }

            else if(value instanceof JSONObject) {
                value = toMap((JSONObject) value);
            }
            map.put(key, value);
        }
        return map;
    }


    public static List<Object> toList(JSONArray array) throws JSONException {
        List<Object> list = new ArrayList<Object>();
        for(int i = 0; i < array.length(); i++) {
            Object value = array.get(i);
            if(value instanceof JSONArray) {
                value = toList((JSONArray) value);
            }

            else if(value instanceof JSONObject) {
                value = toMap((JSONObject) value);
            }
            list.add(value);
        }
        return list;
    }
}

To convert your JSON string to hashmap use this :

HashMap<String, Object> hashMap = new HashMap<>(Utility.jsonToMap(response)) ;

To cater for the schema as well, use this format in SQL 2014

if exists(select 1 from sys.views V inner join sys.[schemas] S on  v.schema_id = s.schema_id where s.name='dbo' and v.name = 'someviewname' and v.type = 'v')
  drop view [dbo].[someviewname];
go

And just throwing it out there, to do stored procedures, because I needed that too:

if exists(select 1
          from sys.procedures p
          inner join sys.[schemas] S on p.schema_id = s.schema_id
          where
              s.name='dbo' and p.name = 'someprocname'
          and p.type in ('p', 'pc')
  drop procedure [dbo].[someprocname];
go

Google shrinks their css classes etc., so it is not easy to identify everything.

Also you have the problem that you have to "wait" until the site shows the result. I would do it like this:

public static void main(String[] args) {

    WebDriver driver = new FirefoxDriver();
    driver.get("http://www.google.com");
    WebElement element = driver.findElement(By.name("q"));
    element.sendKeys("Cheese!\n"); // send also a "\n"
    element.submit();

    // wait until the google page shows the result
    WebElement myDynamicElement = (new WebDriverWait(driver, 10))
              .until(ExpectedConditions.presenceOfElementLocated(By.id("resultStats")));

    List<WebElement> findElements = driver.findElements(By.xpath("//*[@id='rso']//h3/a"));

    // this are all the links you like to visit
    for (WebElement webElement : findElements)
    {
        System.out.println(webElement.getAttribute("href"));
    }
}

This will print you:

• http://de.wikipedia.org/wiki/Cheese
• http://en.wikipedia.org/wiki/Cheese
• http://www.dict.cc/englisch-deutsch/cheese.html
• http://www.cheese.com/

Why would you bother? Load your CSV into Excel like this:

$csv = Join-Path $env:TEMP "process.csv"
$xls = Join-Path $env:TEMP "process.xlsx"

$xl = New-Object -COM "Excel.Application"
$xl.Visible = $true

$wb = $xl.Workbooks.OpenText($csv)

$wb.SaveAs($xls, 51)

You just need to make sure that the CSV export uses the delimiter defined in your regional settings. Override with -Delimiter if need be.

Edit: A more general solution that should preserve the values from the CSV as plain text. Code for iterating over the CSV columns taken from here.

$csv = Join-Path $env:TEMP "input.csv"
$xls = Join-Path $env:TEMP "output.xlsx"

$xl = New-Object -COM "Excel.Application"
$xl.Visible = $true

$wb = $xl.Workbooks.Add()
$ws = $wb.Sheets.Item(1)

$ws.Cells.NumberFormat = "@"

$i = 1
Import-Csv $csv | ForEach-Object {
  $j = 1
  foreach ($prop in $_.PSObject.Properties) {
    if ($i -eq 1) {
      $ws.Cells.Item($i, $j++).Value = $prop.Name
    } else {
      $ws.Cells.Item($i, $j++).Value = $prop.Value
    }
  }
  $i++
}

$wb.SaveAs($xls, 51)
$wb.Close()

$xl.Quit()
[System.Runtime.Interopservices.Marshal]::ReleaseComObject($xl)

Obviously this second approach won't perform too well, because it's processing each cell individually.

I think the key here is understanding the difference between a Class and an Object. An Object is an instance of a Class. But in a fully object-oriented language, a Class is also an Object. So calling .class gets the reference to the Class object of that Class, which can then be manipulated.

The problem is not with extract, which can certainly handle 'military time'. It looks like you have a default timestamp format which has HH instead of HH24; or at least that's the only way I can see to recreate this:

SQL> select value from nls_session_parameters
  2  where parameter = 'NLS_TIMESTAMP_FORMAT';

VALUE
--------------------------------------------------------------------------------
DD-MON-RR HH24.MI.SSXFF

SQL> select extract(hour from cast(to_char(sysdate, 'DD-MON-YYYY HH24:MI:SS')
  2  as timestamp)) from dual;

EXTRACT(HOURFROMCAST(TO_CHAR(SYSDATE,'DD-MON-YYYYHH24:MI:SS')ASTIMESTAMP))
--------------------------------------------------------------------------
                                                                        15

alter session set nls_timestamp_format = 'DD-MON-YYYY HH:MI:SS';

Session altered.

SQL> select extract(hour from cast(to_char(sysdate, 'DD-MON-YYYY HH24:MI:SS')
  2  as timestamp)) from dual;

select extract(hour from cast(to_char(sysdate, 'DD-MON-YYYY HH24:MI:SS') as timestamp)) from dual
                              *
ERROR at line 1:
ORA-01849: hour must be between 1 and 12

So the simple 'fix' is to set the format to something that does recognise 24-hours:

SQL> alter session set nls_timestamp_format = 'DD-MON-YYYY HH24:MI:SS';

Session altered.

SQL> select extract(hour from cast(to_char(sysdate, 'DD-MON-YYYY HH24:MI:SS')
  2  as timestamp)) from dual;

EXTRACT(HOURFROMCAST(TO_CHAR(SYSDATE,'DD-MON-YYYYHH24:MI:SS')ASTIMESTAMP))
--------------------------------------------------------------------------
                                                                        15

Although you don't need the to_char at all:

SQL> select extract(hour from cast(sysdate as timestamp)) from dual;

EXTRACT(HOURFROMCAST(SYSDATEASTIMESTAMP))
-----------------------------------------
                                       15

User property binding instead of function.

GROUP BY 1

I've never known GROUP BY to support using ordinals, only ORDER BY. Either way, only MySQL supports GROUP BY's not including all columns without aggregate functions performed on them. Ordinals aren't recommended practice either because if they're based on the order of the SELECT - if that changes, so does your ORDER BY (or GROUP BY if supported).

There's no need to run GROUP BY on the contents when you're using UNION - UNION ensures that duplicates are removed; UNION ALL is faster because it doesn't - and in that case you would need the GROUP BY...

Your query only needs to be:

SELECT a.id,
       a.time
  FROM dbo.TABLE_A a
UNION
SELECT b.id,
       b.time
  FROM dbo.TABLE_B b

on particular computer color codes can be assigned to different RGB color by editing color values in cmd window properties. Easy click color on color palete and change their rgb values.

If you have HTML like this, for example:

<select id='myselect'>
    <option value='1'>A</option>
    <option value='2'>B</option>
    <option value='3'>C</option>
    <option value='4'>D</option>
</select>
<input type='hidden' id='myhidden' value=''>

All you have to do is bind a function to the change event of the select, and do what you need there:

<script type='text/javascript'>
$(function() {
    $('#myselect').change(function() {
        // if changed to, for example, the last option, then
        // $(this).find('option:selected').text() == D
        // $(this).val() == 4
        // get whatever value you want into a variable
        var x = $(this).val();
        // and update the hidden input's value
        $('#myhidden').val(x);
    });
});
</script>

All things considered, if you're going to be doing a lot of jQuery programming, always have the documentation open. It is very easy to find what you need there if you give it a chance.

Try this code

var path: String = NSBundle.mainBundle().pathForResource("nameOfFile", ofType: "svg")!

        var url: NSURL = NSURL.fileURLWithPath(path)  //Creating a URL which points towards our path

       //Creating a page request which will load our URL (Which points to our path)
        var request: NSURLRequest = NSURLRequest(URL: url)
       webView.loadRequest(request)  //Telling our webView to load our above request

That entire block is misplaced.

class Example(object):
    def main(self):     
        print "Hello World!"

if __name__ == '__main__':
    Example().main()

But you really shouldn't be using a class just to run your main code.

com.sun.tools.javac.util.Pair is an simple implementation of a pair. It can be found in jdk1.7.0_51\lib\tools.jar.

Other than the org.apache.commons.lang3.tuple.Pair, it's not just an interface.

You can just move node_modules into a / folder.

How it works

FROM node:0.12

WORKDIR /worker

COPY package.json /worker/
RUN npm install \
  && mv node_modules /node_modules

COPY . /worker/

I had the same question but figured it out finally. What you most likely need to do is run the following two git commands (replacing hash with the git commit revision number):

git checkout <hash>
git push -f HEAD:master

If you use OmniFaces you can also use it's EL functions like of:formatDate() to format Date objects. You would use it like this:

<h:outputText value="#{of:formatDate(someBean.dateField, 'dd.MM.yyyy HH:mm')}" />

This way you can not only use it for output but also to pass it on to other JSF components.

In Java 8 you can also use .stream().sorted():

myMap.keySet().stream().sorted().forEach(key -> {
        String value = myMap.get(key);

        System.out.println("key: " + key);
        System.out.println("value: " + value);
    }
);

There are many ways to rename the branch, but I am going to focus on the bigger problem: "how to allow clients to fast-forward and not have to mess with their branches locally".

First a quick picture:

This is something actually easy to do; but don't abuse it. The whole idea hinges on merge commits; as they allow fast-forward, and link histories of a branch with another.

renaming the branch:

# rename the branch "master" to "master-old"
# this works even if you are on branch "master"
git branch -m master master-old

creating the new "master" branch:

# create master from new starting point
git branch master <new-master-start-point>

creating a merge commit to have a parent-child history:

# now we've got to fix the new branch...
git checkout master

# ... by doing a merge commit that obsoletes
# "master-old" hence the "ours" strategy.
git merge -s ours master-old

and voila.

git push origin master

This works because creating a merge commit allows fast-forwarding the branch to a new revision.

using a sensible merge commit message:

renamed branch "master" to "master-old" and use commit ba2f9cc as new "master"
-- this is done by doing a merge commit with "ours" strategy which obsoletes
   the branch.

these are the steps I did:

git branch -m master master-old
git branch master ba2f9cc
git checkout master
git merge -s ours master-old

This line:

<input type="password" name="PasswordInput"/>

should have an id attribute, like so:

<input type="password" name="PasswordInput" id="PasswordInput"/>

Base on @Vikram Pudi answer, we can also do like this with pure Javascript

<form onsubmit="submitForm(event)">
    <input type="text">
    <input type="submit">
</form>

<script type="text/javascript">

    function submitForm(event){
        event.preventDefault();


    }
</script>

This removes html code or php if you supplement it. Allows you to add trailing slash and it come up as well as the url without the trailing slash all bypassing the 404 code. Plus a little added security.

Thanks Philip this helped me - my use case was I had a form with lot of input fields so I maintained initial state as object and I was not able to update the object state.The above post helped me :)

Maybe something like this, where you could select more than one element if you'd like?

$("#number").each(function(){
    $(this).val(parseFloat($(this).val()).toFixed(2));
});

In case you have a dump made with sqlplus and the output is garbled as someone did not set those 3 values before, there's a way out.

Just a couple hours ago DB admin send me that ugly looking output of query executed in sqlplus (I dunno, maybe he hates me...). I had to find a way out: this is an awk script to parse that output to make it at least more readable. It's far not perfect, but I did not have enough time to polish it properly. Anyway, it does the job quite well.

awk ' function isDashed(ln){return ln ~ /^---+/};function addLn(){ln2=ln1; ln1=ln0;ln0=$0};function isLoaded(){return l==1||ln2!=""}; function printHeader(){hdr=hnames"\n"hdash;if(hdr!=lastHeader){lastHeader=hdr;print hdr};hnames="";hdash=""};function isHeaderFirstLn(){return isDashed(ln0) && !isDashed(ln1) && !isDashed(ln2) }; function isDataFirstLn(){return isDashed(ln2)&&!isDashed(ln1)&&!isDashed(ln0)}                         BEGIN{_d=1;h=1;hnames="";hdash="";val="";ln2="";ln1="";ln0="";fheadln=""}                                 { addLn();  if(!isLoaded()){next}; l=1;             if(h==1){if(!isDataFirstLn()){if(_d==0){hnames=hnames" "ln1;_d=1;}else{hdash=hdash" "ln1;_d=0}}else{_d=0;h=0;val=ln1;printHeader()}}else{if(!isHeaderFirstLn()){val=val" "ln1}else{print val;val="";_d=1;h=1;hnames=ln1}}   }END{if(val!="")print val}'

In case anyone else would like to try improve this script, below are the variables: hnames -- column names in the header, hdash - dashed below the header, h -- whether I'm currently parsing header (then ==1), val -- the data, _d - - to swap between hnames and hdash, ln0 - last line read, ln1 - line read previously (it's the one i'm actually working with), ln2 - line read before ln1

Happy parsing!

Oh, almost forgot... I use this to prettify sqlplus output myself:

[oracle@ora ~]$ cat prettify_sql 
set lines 256
set trimout on
set tab off
set pagesize 100
set colsep " | "

colsep is optional, but it makes output look like sqlite which is easier to parse using scripts.

EDIT: A little preview of parsed and non-parsed output

Mac OS X: How to change the Terminal shell

I have never used jekyll, but it's main page says that it uses Liquid, and according to their docs, I think the following should work:

<ul> {% for page in site.pages %}     {% if page.title != 'index' %}     <li><div class="drvce"><a href="{{ page.url }}">{{ page.title }}</a></div></li>     {% endif %} {% endfor %} </ul> 

Here is an alternative that is an incremental improvement on several other answers. Assuming settings.aLengthMenu is not multi-dimensional (it can be when DataTables has row lengths and labels) and the data will not change after page load (for simple DOM-loaded DataTables), this function can be inserted to eliminate paging. It hides several paging-related classes.

Perhaps more robust would be setting paging to false inside the function below, however I don't see an API call for that off-hand.

$('#myTable').on('init.dt', function(evt, settings) {
    if (settings && settings.aLengthMenu && settings.fnRecordsTotal && settings.fnRecordsTotal() < settings.aLengthMenu[0]) {
        // hide pagination controls, fewer records than minimum length
        $(settings.nTableWrapper).find('.dataTables_paginate, .dataTables_length, .dataTables_info').hide();
    }
}).DataTable();

Depending on the level of IE support needed, you could also use the :before selector with the bullet style set as the content property.

li {  
  list-style-type: none;
  font-size: small;
}

li:before {
  content: '\2022';
  font-size: x-large;
}

You may have to look up the HTML ASCII for the bullet style you want and use a converter for CSS Hex value.

I'm new to python too. Here is something that looks like will do what you want to

axes([0.08, 0.08, 0.94-0.08, 0.94-0.08]) #[left, bottom, width, height]
axis('scaled')`

I believe this decides the size of the canvas.

Thanks for this tip. I needed the same functionality but on the Server side to check if a Port was in use so I modified it to this code.

 private bool CheckAvailableServerPort(int port) {
    LOG.InfoFormat("Checking Port {0}", port);
    bool isAvailable = true;

    // Evaluate current system tcp connections. This is the same information provided
    // by the netstat command line application, just in .Net strongly-typed object
    // form.  We will look through the list, and if our port we would like to use
    // in our TcpClient is occupied, we will set isAvailable to false.
    IPGlobalProperties ipGlobalProperties = IPGlobalProperties.GetIPGlobalProperties();
    IPEndPoint[] tcpConnInfoArray = ipGlobalProperties.GetActiveTcpListeners();

    foreach (IPEndPoint endpoint in tcpConnInfoArray) {
        if (endpoint.Port == port) {
            isAvailable = false;
            break;
        }
    }

    LOG.InfoFormat("Port {0} available = {1}", port, isAvailable);

    return isAvailable;
}

For DD-MM-YYYY here is a simple workaround to manage string and dates:

insert the date into the string via DD-MMM-YYYY for example 01-11-2017 -> 01-Nov-2017

U can use the FORMAT(date, "dd-mmm-yyyy") to input dates into a string from the spread sheet.

Later, when you output it from a string, it will not confuse the days and months.

These are all good answers, however many forget to close the cursor and database. If you don't close the cursor or database you may run in to memory leaks.

Additionally:
You can get an error when searching by String that contains non alpha/numeric characters. For example: "1a5f9ea3-ec4b-406b-a567-e6927640db40". Those dashes (-) will cause an unrecognized token error. You can overcome this by putting the string in an array. So make it a habit to query like this:

public boolean hasObject(String id) {
    SQLiteDatabase db = getWritableDatabase();
    String selectString = "SELECT * FROM " + _TABLE + " WHERE " + _ID + " =?";

    // Add the String you are searching by here. 
    // Put it in an array to avoid an unrecognized token error 
    Cursor cursor = db.rawQuery(selectString, new String[] {id}); 

    boolean hasObject = false;
    if(cursor.moveToFirst()){
        hasObject = true;

        //region if you had multiple records to check for, use this region. 

        int count = 0;
        while(cursor.moveToNext()){
          count++;
        }
        //here, count is records found
        Log.d(TAG, String.format("%d records found", count));

        //endregion

    } 

    cursor.close();          // Dont forget to close your cursor
    db.close();              //AND your Database!
    return hasObject;
}

An XPath solution is to use:

string-length((//div[@class='contest'])[$k])

where $k should be substituted by a number.

This evaluates to the string length of the $k-th (in document order) div in the XML document that has a class attribute with value 'contest'.

If you want to be able to have a SELECT without problems of the parent id having to be lower than child id, a function could be used. It supports also multiple children (as a tree should do) and the tree can have multiple heads. It also ensure to break if a loop exists in the data.

I wanted to use dynamic SQL to be able to pass the table/columns names, but functions in MySQL don't support this.

DELIMITER $$

CREATE FUNCTION `isSubElement`(pParentId INT, pId INT) RETURNS int(11)
DETERMINISTIC    
READS SQL DATA
BEGIN
DECLARE isChild,curId,curParent,lastParent int;
SET isChild = 0;
SET curId = pId;
SET curParent = -1;
SET lastParent = -2;

WHILE lastParent <> curParent AND curParent <> 0 AND curId <> -1 AND curParent <> pId AND isChild = 0 DO
    SET lastParent = curParent;
    SELECT ParentId from `test` where id=curId limit 1 into curParent;

    IF curParent = pParentId THEN
        SET isChild = 1;
    END IF;
    SET curId = curParent;
END WHILE;

RETURN isChild;
END$$

Here, the table test has to be modified to the real table name and the columns (ParentId,Id) may have to be adjusted for your real names.

Usage :

SET @wantedSubTreeId = 3;
SELECT * FROM test WHERE isSubElement(@wantedSubTreeId,id) = 1 OR ID = @wantedSubTreeId;

Result :

3   7   k
5   3   d
9   3   f
1   5   a

SQL for test creation :

CREATE TABLE IF NOT EXISTS `test` (
  `Id` int(11) NOT NULL,
  `ParentId` int(11) DEFAULT NULL,
  `Name` varchar(300) NOT NULL,
  PRIMARY KEY (`Id`)
) ENGINE=InnoDB  DEFAULT CHARSET=latin1;

insert into test (id, parentid, name) values(3,7,'k');
insert into test (id, parentid, name) values(5,3,'d');
insert into test (id, parentid, name) values(9,3,'f');
insert into test (id, parentid, name) values(1,5,'a');
insert into test (id, parentid, name) values(6,2,'o');
insert into test (id, parentid, name) values(2,8,'c');

EDIT : Here is a fiddle to test it yourself. It forced me to change the delimiter using the predefined one, but it works.

This is really just an expansion of BBB's answer which lead to to get my experiment working.

This script will simply create a file /tmp/testfile when you click on the button that says "Open Script".

This requires 3 files.

1. The actual HTML Website with a button.
2. A php script which executes the script
3. A Script

The File Tree:

root@test:/var/www/html# tree testscript/
testscript/
+-- index.html
+-- testexec.php
+-- test.sh

1. The main WebPage:

root@test:/var/www/html# cat testscript/index.html
<form action="/testscript/testexec.php">
    <input type="submit" value="Open Script">
</form>

2. The PHP Page that runs the script and redirects back to the main page:

root@test:/var/www/html# cat testscript/testexec.php
<?php
shell_exec("/var/www/html/testscript/test.sh");
header('Location: http://192.168.1.222/testscript/index.html?success=true');
?>

3. The Script :

root@test:/var/www/html# cat testscript/test.sh

#!/bin/bash

touch /tmp/testfile

http://graph.facebook.com/" + facebookId + "/picture?type=square For instance: http://graph.facebook.com/67563683055/picture?type=square

There are also more sizes besides "square". See the docs.

Update September 2020
As Facebook have updated their docs this method is not working anymore without a token. You need to append some kind of access_token. You can find further information and how to do it correctly in the fb docs to the graph api of user picture

Requirements Change This endpoint supports App-Scoped User IDs (ASID), User IDs (UID), and Page-Scoped User IDs (PSID). Currently you can query ASIDs and UIDs with no requirements. However, beginning October 24, 2020, an access token will be required for all UID-based queries. If you query a UID and thus must include a token:

use a User access token for Facebook Login authenticated requests
use a Page access token for page-scoped requests
use an App access token for server-side requests
use a Client access token for mobile or web client-side requests

Quote of fb docs

I'm on version 2.4.9 and using a config file. The service wouldn't start until I surrounded the equals sign in the config file with spaces:

dbpath = D:\Mongo data
logpath = C:\mongodb\logs\mongo.log 
logappend = true

Originally I had:

logpath=C:\mongodb\logs\mongo.log 

I also discovered that when installing the service that you have to use an absolute path for the config file eg:

c:\mongodb\bin\>mongodb.exe C:\mongodb\bin\mongod.conf --install

Don't be tempted to put inverted commas around a dbpath with spaces. The service will appear to start when you execute net start MongoDB but it will terminate. Check the log files for confirmation that the service has really started.

Regarding the answer from Michael Wyraz, where you use alt*DeploymentRepository in your settings.xml or command on the line, be careful if you are using version 3.0.0-M1 of the maven-deploy-plugin (which is the latest version at the time of writing), there is a bug in this version that could cause a server authentication issue.

A workaround is as follows. In the value:

releases::default::https://YOUR_NEXUS_URL/releases

you need to remove the default section, making it:

releases::https://YOUR_NEXUS_URL/releases

The prior version 2.8.2 does not have this bug.

While you cannot modify a column as such, you may operate on a column and return a new DataFrame reflecting that change. For that you'd first create a UserDefinedFunction implementing the operation to apply and then selectively apply that function to the targeted column only. In Python:

from pyspark.sql.functions import UserDefinedFunction
from pyspark.sql.types import StringType

name = 'target_column'
udf = UserDefinedFunction(lambda x: 'new_value', StringType())
new_df = old_df.select(*[udf(column).alias(name) if column == name else column for column in old_df.columns])

new_df now has the same schema as old_df (assuming that old_df.target_column was of type StringType as well) but all values in column target_column will be new_value.

Bootstrap 3

Here is a working left sidebar example:

http://bootply.com/90936 (similar to the Bootstrap docs)

The trick is using the affix component along with some CSS to position it:

  #sidebar.affix-top {
    position: static;
    margin-top:30px;
    width:228px;
  }

  #sidebar.affix {
    position: fixed;
    top:70px;
    width:228px;
  }

EDIT- Another example with footer and affix-bottom

Bootstrap 4

The Affix component has been removed in Bootstrap 4, so to create a sticky sidebar, you can use a 3rd party Affix plugin like this Bootstrap 4 sticky sidebar example, or use the sticky-top class is explained in this answer.

Related: Create a responsive navbar sidebar "drawer" in Bootstrap 4?

I fixed in the below way with typescript

1. Define and initialize firest

pageNumbers: number[] = [];

2. than populate it

   for (let i = 1; i < 201; i++) {
       this.pageNumbers.push(i);
   }
   

import codecs

decode_hex = codecs.getdecoder("hex_codec")

# for an array
msgs = [decode_hex(msg)[0] for msg in msgs]

# for a string
string = decode_hex(string)[0]

Go to run as and choose Run Configurations -> Common and in the Standard Input and Output you can choose a File also.

With your question edit, I see your problem. Let's say the current directory is /home/yourname ... in this case, your command below:

sed 's/xxx/'$PWD'/'

will be expanded to

sed `s/xxx//home/yourname//

which is not valid. You need to put a \ character in front of each / in your $PWD if you want to do this.

Ok @Adam and @Kimvais were right, paramiko cannot parse .ppk files.

So the way to go (thanks to @JimB too) is to convert .ppk file to openssh private key format; this can be achieved using Puttygen as described here.

Then it's very simple getting connected with it:

import paramiko
ssh = paramiko.SSHClient()

ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())

ssh.connect('<hostname>', username='<username>', password='<password>', key_filename='<path/to/openssh-private-key-file>')

stdin, stdout, stderr = ssh.exec_command('ls')
print stdout.readlines()
ssh.close()

If you are looking for 1st Number with decimal as string has correct decimal places, you may try regexp_substr function like this:

regexp_substr('stack12.345overflow', '\.*[[:digit:]]+\.*[[:digit:]]*')

It took me a while, but here's how I made it dynamic. It doesn't depend on a sorted table.

First I started with a column of state names (Column A) and a column of aircraft in each state (Column B). (Row 1 is a header row).

Finding the cell that contains the number of aircraft was:

=MATCH(MAX($B$2:$B$54),$B$2:$B$54,0)+MIN(ROW($B$2:$B$54))-1

I put that into a cell and then gave that cell a name, "StateRow" Then using the tips from above, I wound up with this:

=INDIRECT(ADDRESS(StateRow,1))

This returns the name of the state from the dynamic value in row "StateRow", column 1

Now, as the values in the count column change over time as more data is entered, I always know which state has the most aircraft.

Logically, Cody's answer should work. However I don't think the command prompt handles a code block logically. For the life of me I can't get that to work properly with any more than a single command within the block. In my case, extensive testing revealed that all of the commands within the block are being cached, and executed simultaneously at the end of the block. This of course doesn't yield the expected results. Here is an oversimplified example:

if %ERRORLEVEL%==0 (
set var1=blue
set var2=cheese
set var3=%var1%_%var2%
)

This should provide var3 with the following value:

blue_cheese

but instead yields:

_

because all 3 commands are cached and executed simultaneously upon exiting the code block.

I was able to overcome this problem by re-writing the if block to only execute one command - goto - and adding a few labels. Its clunky, and I don't much like it, but at least it works.

if %ERRORLEVEL%==0 goto :error0
goto :endif

:error0
set var1=blue
set var2=cheese
set var3=%var1%_%var2%

:endif

You can modify the path on the config.xml file in the default directory

<projectNamingStrategy class="jenkins.model.ProjectNamingStrategy$DefaultProjectNamingStrategy"/>
<workspaceDir>D:/Workspace/${ITEM_FULL_NAME}</workspaceDir>
<buildsDir>D:/Logs/${ITEM_ROOTDIR}/Build</buildsDir>

In Python 3 it's quite easy: read the file and rewrite it with utf-8 encoding:

s = open(bom_file, mode='r', encoding='utf-8-sig').read()
open(bom_file, mode='w', encoding='utf-8').write(s)

Delete node_module directory and run below in command line

rm -rf node_modules
rm package-lock.json yarn.lock
npm cache clear --force
npm install

If still not working, try below

npm install webpack --save

Removing "Launch screen interface file base name" from Info.plist file AND trashing "Launch Screen.xib" worked for me.

This worked for me:

SET SESSION sql_mode=(SELECT REPLACE(@@sql_mode,'ONLY_FULL_GROUP_BY',''));

trunc(tran_date) = trunc(sysdate -1)

Try something like this inside ThisOutlookSession:

Private Sub Application_NewMail()
    Call Your_main_macro
End Sub

My outlook vba just fired when I received an email and had that application event open.

Edit: I just tested a hello world msg box and it ran after being called in the application_newmail event when an email was received.

You should add a view to a bottom of the UISearchBar

let rect = searchController.searchBar.frame;
let lineView : UIView = UIView.init(frame: CGRect.init(x: 0, y: rect.size.height-1, width: rect.size.width, height: 1))
lineView.backgroundColor = UIColor.init(hexString: "8CC73E")
searchController.searchBar.addSubview(lineView)

The easiest way is to use a for loop template tag.

Given the view:

def MyView(request):
    ...
    query_results = YourModel.objects.all()
    ...
    #return a response to your template and add query_results to the context

You can add a snippet like this your template...

<table>
    <tr>
        <th>Field 1</th>
        ...
        <th>Field N</th>
    </tr>
    {% for item in query_results %}
    <tr> 
        <td>{{ item.field1 }}</td>
        ...
        <td>{{ item.fieldN }}</td>
    </tr>
    {% endfor %}
</table>

This is all covered in Part 3 of the Django tutorial. And here's Part 1 if you need to start there.

var a=new Array('a','b','c');
var b=new Array('d','e','f');
var d=new Array('x','y','z');
var c=a.concat(b,d)

Does that solve your problem ?

Just use Analyze | Inspect Code with appropriate inspection enabled (Unused declaration under Declaration redundancy group).

Using IntelliJ 11 CE you can now "Analyze | Run Inspection by Name ... | Unused declaration"

See triangle numbers.

Another way:

if (s.size > 5) s.reverse.substring(5).reverse

BTW, this is Scala code. May need brackets to work in Java.

Difference HTML properties and attributes:

Let's first look at the definitions of these words before evaluating what the difference is in HTML:

English definition:

• Attributes are referring to additional information of an object.
• Properties are describing the characteristics of an object.

In HTML context:

When the browser parses the HTML, it creates a tree data structure wich basically is an in memory representation of the HTML. It the tree data structure contains nodes which are HTML elements and text. Attributes and properties relate to this is the following manner:

• Attributes are additional information which we can put in the HTML to initialize certain DOM properties.
• Properties are formed when the browser parses the HTML and generates the DOM. Each of the elements in the DOM have their own set of properties which are all set by the browser. Some of these properties can have their initial value set by HTML attributes. Whenever a DOM property changes which has influence on the rendered page, the page will be immediately re rendered

It is also important to realize that the mapping of these properties is not 1 to 1. In other words, not every attribute which we give on an HTML element will have a similar named DOM property.

Furthermore have different DOM elements different properties. For example, an <input> element has a value property which is not present on a <div> property.

Example:

Let's take the following HTML document:

 <!DOCTYPE html>
<html>
<head>
  <meta charset="utf-8">  <!-- charset is a attribute -->
  <meta name="viewport" content="width=device-width"> <!-- name and content are attributes -->
  <title>JS Bin</title>
</head>
<body>
<div id="foo" class="bar foobar">hi</div> <!-- id and class are attributes -->
</body>
</html>

Then we inspect the <div>, in the JS console:

 console.dir(document.getElementById('foo'));

We see the following DOM properties (chrome devtools, not all properties shown):

• We can see that the attribute id in the HTML is now also a id property in the DOM. The id has been initialized by the HTML (although we could change it with javascript).
• We can see that the class attribute in the HTML has no corresponding class property (class is reserved keyword in JS). But actually 2 properties, classList and className.

I had angular-cli version 1.0.0-beta.28.3, and the only thing that worked for me was deleting the angular-cli directly from the global node_modules folder:

cd /usr/local/bin/lib/node_modules
rm -rf angular-cli

After that ng version output was, as expected:

command not found: ng

And I could install the latest angular-cli version:

npm install -g @angular/cli@latest

Hope it helps...

you can simply disable maximize inside form constructor.

 public Form1(){
     InitializeComponent();
     MaximizeBox = false;
 }

to minimize when closing.

private void Form1_FormClosing(Object sender, FormClosingEventArgs e) {
    e.Cancel = true;
    WindowState = FormWindowState.Minimized;
}

(Paper) Printing or Saving as HTML

For those of you wishing to print to paper the outputs the above answers alone seem not to give a nice final output. However, taking @Max Masnick's code and adding the following allows one to print it on a full A4 page.

from IPython.display import display
from IPython.display import HTML
import IPython.core.display as di

di.display_html('<script>jQuery(function() {if (jQuery("body.notebook_app").length == 0) { jQuery(".input_area").toggle(); jQuery(".prompt").toggle();}});</script>', raw=True)

CSS = """#notebook div.output_subarea {max-width:100%;}""" #changes output_subarea width to 100% (from 100% - 14ex)
HTML('<style>{}</style>'.format(CSS))

The reason for the indent is that the prompt section removed by Max Masnick means everything shifts to the left on output. This however did nothing for the maximum width of the output which was restricted to max-width:100%-14ex;. This changes the max width of the output_subarea to max-width:100%;.

I had the same problem. Firefox showed me this error but in chrome everything was OK. then after a google search, i used google cdn for jquery in index.html instead of loading local js file and the problem solved.

This is example of my own UserControl with Up and Down key catching.

Xaml code:

<Grid>
    <Grid.ColumnDefinitions>
        <ColumnDefinition Width="*" />
        <ColumnDefinition Width="13" />
    </Grid.ColumnDefinitions>
    <Grid.RowDefinitions>
        <RowDefinition Height="13" />
        <RowDefinition Height="13" />
    </Grid.RowDefinitions>
    <TextBox Name="NUDTextBox"  Grid.Column="0" Grid.Row="0" Grid.RowSpan="2" TextAlignment="Right" PreviewKeyDown="NUDTextBox_PreviewKeyDown" PreviewKeyUp="NUDTextBox_PreviewKeyUp" TextChanged="NUDTextBox_TextChanged"/>
    <RepeatButton Name="NUDButtonUP"  Grid.Column="1" Grid.Row="0" FontSize="8" FontFamily="Marlett" VerticalContentAlignment="Center" HorizontalContentAlignment="Center" Click="NUDButtonUP_Click">5</RepeatButton>
    <RepeatButton Name="NUDButtonDown"  Grid.Column="1" Grid.Row="1" FontSize="8"  FontFamily="Marlett" VerticalContentAlignment="Center" HorizontalContentAlignment="Center" Height="13" VerticalAlignment="Bottom" Click="NUDButtonDown_Click">6</RepeatButton>
</Grid>

And the code:

public partial class NumericUpDown : UserControl
{
    int minvalue = 0, 
        maxvalue = 100,
        startvalue = 10;
    public NumericUpDown()
    {
        InitializeComponent();
        NUDTextBox.Text = startvalue.ToString();
    }

    private void NUDButtonUP_Click(object sender, RoutedEventArgs e)
    {
        int number;
        if (NUDTextBox.Text != "") number = Convert.ToInt32(NUDTextBox.Text);
        else number = 0;
        if (number < maxvalue)
            NUDTextBox.Text = Convert.ToString(number + 1); 
    }

    private void NUDButtonDown_Click(object sender, RoutedEventArgs e)
    {
        int number;
        if (NUDTextBox.Text != "") number = Convert.ToInt32(NUDTextBox.Text);
        else number = 0;
        if (number > minvalue)
            NUDTextBox.Text = Convert.ToString(number - 1); 
    }

    private void NUDTextBox_PreviewKeyDown(object sender, KeyEventArgs e)
    {

i get the solution. i've using cygwin and this is the problem the rsync command for Windows work only in windows shell and works in the windows powershell.

A few times it has happened the same error between two linux boxes. and appears to be by incompatible versions of rsync

Lets see, numeric (3,2). That means you have 3 places for data and two of them are to the right of the decimal leaving only one to the left of the decimal. 15 has two places to the left of the decimal. BTW if you might have 100 as a value I'd increase that to numeric (5, 2)

You could use position: sticky

#navbar {
  position: sticky;
  top: 0px;
}

The #navbar should be a direct child of the body though.

You can parse the text as a string, which creates an Element, and create an ElementTree using that Element.

import xml.etree.ElementTree as ET
tree = ET.ElementTree(ET.fromstring(xmlstring))

I just came across this issue and the documentation, while complete, is not very straightforward on the difference in usage between the parse() and fromstring() methods.

If you have to display the field on report header then try this... RightClick on Textbox > Properties > Category > date > select *Format (Note this will maintain the regional settings).

Since this question has been viewed many times, I'm posting it... Hope it helps.

Now you can add/use instances with in the method

public class Myprogram7 {

  Scanner scan;
  int compareCount = 0;
  int low = 0;
  int high = 0;
  int mid = 0;  
  int key = 0;  
  Scanner temp;  
  int[]list;  
  String menu, outputString;  
  int option = 1;  
  boolean found = false;  

  private void readLine() {

  }

  private void findkey() {

  }

  private void printCount() {

  }
  public static void main(String[] args){

    Myprogram7 myprg=new Myprogram7();
    myprg.readLine();
    myprg.findkey();
    myprg.printCount();
  }
}

You can use clientWidth or offsetWidth Mozilla developer network reference

It would be like:

document.getElementById("yourDiv").clientWidth; // returns number, like 728

or with borders width :

document.getElementById("yourDiv").offsetWidth; // 728 + borders width

If you want to stop every movie tag in your page from playing, this little snippet of jQuery will help you:

$("video").each(function () { this.pause() });

Use different format or pattern to get the information from the date

var myDate = new Date("2015-06-17 14:24:36");_x000D_
console.log(moment(myDate).format("YYYY-MM-DD HH:mm:ss"));_x000D_
console.log("Date: "+moment(myDate).format("YYYY-MM-DD"));_x000D_
console.log("Year: "+moment(myDate).format("YYYY"));_x000D_
console.log("Month: "+moment(myDate).format("MM"));_x000D_
console.log("Month: "+moment(myDate).format("MMMM"));_x000D_
console.log("Day: "+moment(myDate).format("DD"));_x000D_
console.log("Day: "+moment(myDate).format("dddd"));_x000D_
console.log("Time: "+moment(myDate).format("HH:mm")); // Time in24 hour format_x000D_
console.log("Time: "+moment(myDate).format("hh:mm A"));

To capitalize on the answer of Alex D, using refinements:

module CoreExtensions
  module Integerable
    refine String do
      def integer?
        Integer(self)
      rescue ArgumentError
        false
      else
        true
      end
    end
  end
end

Later, in you class:

require 'core_ext/string/integerable'

class MyClass
  using CoreExtensions::Integerable

  def method
    'my_string'.integer?
  end
end

$imageURL = getFacebookImageFromURL($url);

I recommend this library from Hannes Dorfmann. It encapsulates all the logic related to particular view type in a separate object called "AdapterDelegate". https://github.com/sockeqwe/AdapterDelegates

public class CatAdapterDelegate extends AdapterDelegate<List<Animal>> {

  private LayoutInflater inflater;

  public CatAdapterDelegate(Activity activity) {
    inflater = activity.getLayoutInflater();
  }

  @Override public boolean isForViewType(@NonNull List<Animal> items, int position) {
    return items.get(position) instanceof Cat;
  }

  @NonNull @Override public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent) {
    return new CatViewHolder(inflater.inflate(R.layout.item_cat, parent, false));
  }

  @Override public void onBindViewHolder(@NonNull List<Animal> items, int position,
      @NonNull RecyclerView.ViewHolder holder, @Nullable List<Object> payloads) {

    CatViewHolder vh = (CatViewHolder) holder;
    Cat cat = (Cat) items.get(position);

    vh.name.setText(cat.getName());
  }

  static class CatViewHolder extends RecyclerView.ViewHolder {

    public TextView name;

    public CatViewHolder(View itemView) {
      super(itemView);
      name = (TextView) itemView.findViewById(R.id.name);
    }
  }
}

public class AnimalAdapter extends ListDelegationAdapter<List<Animal>> {

  public AnimalAdapter(Activity activity, List<Animal> items) {

    // DelegatesManager is a protected Field in ListDelegationAdapter
    delegatesManager.addDelegate(new CatAdapterDelegate(activity))
                    .addDelegate(new DogAdapterDelegate(activity))
                    .addDelegate(new GeckoAdapterDelegate(activity))
                    .addDelegate(23, new SnakeAdapterDelegate(activity));

    // Set the items from super class.
    setItems(items);
  }
}

d <- 5
for(i in 1:10) {

I'm using Android Studio and as of 19th of January 2016 this did the trick for me. (This seems like something that changes every year or so)

Go to: app -> Gradle Scripts -> build.gradle (Module: app)

Then under model { ... android.ndk { ... and add a line: stl = "gnustl_shared"

Like this:

model {

    ...

    android.ndk {
        moduleName = "gl2jni"
        cppFlags.add("-Werror")
        ldLibs.addAll(["log", "GLESv2"])
        stl = "gnustl_shared"     //  <-- this is the line that I added
    }

    ...

}

function printCrossword(printContainer) {
    var DocumentContainer = getElement(printContainer);
    var WindowObject = window.open('', "PrintWindow", "width=5,height=5,top=200,left=200,toolbars=no,scrollbars=no,status=no,resizable=no");
    WindowObject.document.writeln(DocumentContainer.innerHTML);
    WindowObject.document.close();
    WindowObject.focus();
    WindowObject.print();
    WindowObject.close();
}

Or for custom options

<%= f.select :desired_attribute, ['option1', 'option2']%>

Even though I'm sort of a broken clock with this one, Java XML API uses Factory a lot. I mean just look at this:

Document doc = DocumentBuilderFactory.newInstance().newDocumentBuilder().parse(source);
String title = XPathFactory.newInstance().newXPath().evaluate("//title", doc);

...and so on and so forth.

Additionally various Buffers (StringBuffer, ByteBuffer, StringBuilder) use Builder.

You don't have sufficient permissions to write to the root directory. See the leading slash on the filename?

I'm not quite sure what you mean by "sorting the items after index 0", but if you just want to sort the array of strings returned by SerialPort.GetPortNames(), you can use Array.Sort.

If the variable holding the dataframe is called df, then:

len(df.columns)

gives the number of columns.

And for those who want the number of rows:

len(df.index)

For a tuple containing the number of both rows and columns:

df.shape

 ;(function($){
        // your code
    })(jQuery);

Place your js code inside the closure above , it should solve the problem.

STR_TO_DATE allows you to do this, and it has a format argument.

I had done a detailed comparison of dupes removal at some other question but having noticed that this is the real place i just wanted to share it here as well.

I believe this is the best way to do this

var myArray = [100, 200, 100, 200, 100, 100, 200, 200, 200, 200],_x000D_
    reduced = Object.keys(myArray.reduce((p,c) => (p[c] = true,p),{}));_x000D_
console.log(reduced);

OK .. even though this one is O(n) and the others are O(n^2) i was curious to see benchmark comparison between this reduce / look up table and filter/indexOf combo (I choose Jeetendras very nice implementation https://stackoverflow.com/a/37441144/4543207). I prepare a 100K item array filled with random positive integers in range 0-9999 and and it removes the duplicates. I repeat the test for 10 times and the average of the results show that they are no match in performance.

• In firefox v47 reduce & lut : 14.85ms vs filter & indexOf : 2836ms
• In chrome v51 reduce & lut : 23.90ms vs filter & indexOf : 1066ms

Well ok so far so good. But let's do it properly this time in the ES6 style. It looks so cool..! But as of now how it will perform against the powerful lut solution is a mystery to me. Lets first see the code and then benchmark it.

var myArray = [100, 200, 100, 200, 100, 100, 200, 200, 200, 200],_x000D_
    reduced = [...myArray.reduce((p,c) => p.set(c,true),new Map()).keys()];_x000D_
console.log(reduced);

Wow that was short..! But how about the performance..? It's beautiful... Since the heavy weight of the filter / indexOf lifted over our shoulders now i can test an array 1M random items of positive integers in range 0..99999 to get an average from 10 consecutive tests. I can say this time it's a real match. See the result for yourself :)

var ranar = [],_x000D_
     red1 = a => Object.keys(a.reduce((p,c) => (p[c] = true,p),{})),_x000D_

_x000D_
console.log("reduce & lut took: " + avg1 + "msec");_x000D_
console.log("map & spread took: " + avg2 + "msec");

Which one would you use..? Well not so fast...! Don't be deceived. Map is at displacement. Now look... in all of the above cases we fill an array of size n with numbers of range < n. I mean we have an array of size 100 and we fill with random numbers 0..9 so there are definite duplicates and "almost" definitely each number has a duplicate. How about if we fill the array in size 100 with random numbers 0..9999. Let's now see Map playing at home. This time an Array of 100K items but random number range is 0..100M. We will do 100 consecutive tests to average the results. OK let's see the bets..! <- no typo

var ranar = [],_x000D_
     red1 = a => Object.keys(a.reduce((p,c) => (p[c] = true,p),{})),_x000D_
     red2 = a => reduced = [...a.reduce((p,c) => p.set(c,true),new Map()).keys()],_x000D_
     avg1 = [],_x000D_
     avg2 = [],_x000D_
       ts = 0,_x000D_
       te = 0,_x000D_
     res1 = [],_x000D_
     res2 = [],_x000D_
     count= 100;_x000D_
for (var i = 0; i<count; i++){_x000D_
  ranar = (new Array(100000).fill(true)).map(e => Math.floor(Math.random()*100000000));_x000D_
  ts = performance.now();_x000D_
  res1 = red1(ranar);_x000D_
  te = performance.now();_x000D_
  avg1.push(te-ts);_x000D_
  ts = performance.now();_x000D_
  res2 = red2(ranar);_x000D_
  te = performance.now();_x000D_
  avg2.push(te-ts);_x000D_
}_x000D_
_x000D_
avg1 = avg1.reduce((p,c) => p+c)/count;_x000D_
avg2 = avg2.reduce((p,c) => p+c)/count;_x000D_
_x000D_
console.log("reduce & lut took: " + avg1 + "msec");_x000D_
console.log("map & spread took: " + avg2 + "msec");

Now this is the spectacular comeback of Map()..! May be now you can make a better decision when you want to remove the dupes.

Well ok we are all happy now. But the lead role always comes last with some applause. I am sure some of you wonder what Set object would do. Now that since we are open to ES6 and we know Map is the winner of the previous games let us compare Map with Set as a final. A typical Real Madrid vs Barcelona game this time... or is it? Let's see who will win the el classico :)

var ranar = [],_x000D_
     red1 = a => reduced = [...a.reduce((p,c) => p.set(c,true),new Map()).keys()],_x000D_
     red2 = a => Array.from(new Set(a)),_x000D_
     avg1 = [],_x000D_
     avg2 = [],_x000D_
       ts = 0,_x000D_
       te = 0,_x000D_
     res1 = [],_x000D_
     res2 = [],_x000D_
     count= 100;_x000D_
for (var i = 0; i<count; i++){_x000D_
  ranar = (new Array(100000).fill(true)).map(e => Math.floor(Math.random()*10000000));_x000D_
  ts = performance.now();_x000D_
  res1 = red1(ranar);_x000D_
  te = performance.now();_x000D_
  avg1.push(te-ts);_x000D_
  ts = performance.now();_x000D_
  res2 = red2(ranar);_x000D_
  te = performance.now();_x000D_
  avg2.push(te-ts);_x000D_
}_x000D_
_x000D_
avg1 = avg1.reduce((p,c) => p+c)/count;_x000D_
avg2 = avg2.reduce((p,c) => p+c)/count;_x000D_
_x000D_
console.log("map & spread took: " + avg1 + "msec");_x000D_
console.log("set & A.from took: " + avg2 + "msec");

Wow.. man..! Well unexpectedly it didn't turn out to be an el classico at all. More like Barcelona FC against CA Osasuna :))

With python >= 3.5 you can use mock_object.assert_not_called().

Well According to a comment on the shuf answer he shuffed 78 000 000 000 lines in under a minute.

Challenge accepted...

EDIT: I beat my own record

powershuf did it in 0.047 seconds

$ time ./powershuf.py -n 10 --file lines_78000000000.txt > /dev/null 
./powershuf.py -n 10 --file lines_78000000000.txt > /dev/null  0.02s user 0.01s system 80% cpu 0.047 total

The reason it is so fast, well I don't read the whole file and just move the file pointer 10 times and print the line after the pointer.

Gitlab Repo

Old attempt

First I needed a file of 78.000.000.000 lines:

seq 1 78 | xargs -n 1 -P 16 -I% seq 1 1000 | xargs -n 1 -P 16 -I% echo "" > lines_78000.txt
seq 1 1000 | xargs -n 1 -P 16 -I% cat lines_78000.txt > lines_78000000.txt
seq 1 1000 | xargs -n 1 -P 16 -I% cat lines_78000000.txt > lines_78000000000.txt

This gives me a a file with 78 Billion newlines ;-)

Now for the shuf part:

$ time shuf -n 10 lines_78000000000.txt










shuf -n 10 lines_78000000000.txt  2171.20s user 22.17s system 99% cpu 36:35.80 total

The bottleneck was CPU and not using multiple threads, it pinned 1 core at 100% the other 15 were not used.

Python is what I regularly use so that's what I'll use to make this faster:

#!/bin/python3
import random
f = open("lines_78000000000.txt", "rt")
count = 0
while 1:
  buffer = f.read(65536)
  if not buffer: break
  count += buffer.count('\n')

for i in range(10):
  f.readline(random.randint(1, count))

This got me just under a minute:

$ time ./shuf.py         










./shuf.py  42.57s user 16.19s system 98% cpu 59.752 total

I did this on a Lenovo X1 extreme 2nd gen with the i9 and Samsung NVMe which gives me plenty read and write speed.

I know it can get faster but I'll leave some room to give others a try.

Or in case you just need the value of the first seleted sell (or just one selected cell if one is selected)

TextBox1.Text = SelectedCells[0].Value.ToString();

you should add python to your PATH during installation of python...after installation.. open cmd prompt type command-pip install nltk then go to IDLE and open a new file..save it as file.py..then open file.py type the following: import nltk

nltk.download()

I'm aware that question is quite old, but it's still popular and I can't see any solution for ASP.net Core.

I case of ASP.net Core, you need to add new JsonOutputFormatter in Startup.cs file:

    public void ConfigureServices(IServiceCollection services)
    {

        services.AddMvc(options =>
        {
            options.OutputFormatters.Clear();
            options.OutputFormatters.Add(new JsonOutputFormatter(new JsonSerializerSettings()
            {
                ReferenceLoopHandling = ReferenceLoopHandling.Ignore,
            }, ArrayPool<char>.Shared));
        });

        //...
    }

After implementing it, JSON serializer will simply ignore loop references. What it means is: it will return null instead of infinitely loading objects referencing each other.

Without above solution using:

var employees = db.Employees.ToList();

Would load Employees and related to them Departments.

After setting ReferenceLoopHandling to Ignore, Departments will be set to null unless you include it in your query:

var employees = db.Employees.Include(e => e.Department);

Also, keep in mind that it will clear all OutputFormatters, if you don't want that you can try removing this line:

options.OutputFormatters.Clear();

But removing it causes again self referencing loop exception in my case for some reason.

If you want to create a file and write and append data to it many times, then use the below code, it will create file if not exits and will append data if it exists.

 SimpleDateFormat formatter = new SimpleDateFormat("yyyy_MM_dd");
        Date now = new Date();
        String fileName = formatter.format(now) + ".txt";//like 2016_01_12.txt


         try
            {
                File root = new File(Environment.getExternalStorageDirectory()+File.separator+"Music_Folder", "Report Files");
                //File root = new File(Environment.getExternalStorageDirectory(), "Notes");
                if (!root.exists()) 
                {
                    root.mkdirs();
                }
                File gpxfile = new File(root, fileName);


                FileWriter writer = new FileWriter(gpxfile,true);
                writer.append(sBody+"\n\n");
                writer.flush();
                writer.close();
                Toast.makeText(this, "Data has been written to Report File", Toast.LENGTH_SHORT).show();
            }
            catch(IOException e)
            {
                 e.printStackTrace();

            }

This can be done quite easily if you:

1. Use str to convert the number into a string so that you can iterate over it.

2. Use a list comprehension to split the string into individual digits.

3. Use int to convert the digits back into integers.

Below is a demonstration:

>>> n = 43365644
>>> [int(d) for d in str(n)]
[4, 3, 3, 6, 5, 6, 4, 4]
>>>

Short (un-precise) definition:

Compiled language: Entire program is translated to machine code at once, then the machine code is run by the CPU.

Interpreted language: Program is read line-by-line and as soon as a line is read the machine instructions for that line are executed by the CPU.

But really, few languages these days are purely compiled or purely interpreted, it often is a mix. For a more detailed description with pictures, see this thread:

What is the difference between compilation and interpretation?

This is how I do it using Google Gson. I am not sure, if there are a simpler way to do this.( with or without an external library).

 Type collectionType = new TypeToken<List<Class>>() {
                } // end new
                        .getType();

                String gsonString = 
                new Gson().toJson(objList, collectionType);

<input type="text" name="field" maxlength="8"
    onkeypress="return onlyAlphabets(event,this);" />

function onlyAlphabets(e, t) {
            try {
                if (window.event) {
                    var charCode = window.event.keyCode;
                }
                else if (e) {
                    var charCode = e.which;
                }
                else { return true; }
                if ((charCode > 64 && charCode < 91) || (charCode > 96 && charCode < 123))
                    return true;
                else
                    return false;
            }
            catch (err) {
                alert(err.Description);
            }
        }

You can change the font size in R Markdown with HTML code tags <font size="1"> your text </font> . This code is added to the R Markdown document and will alter the output of the HTML output.

For example:

 <font size="1"> This is my text number1</font> _x000D_
_x000D_
 <font size="2"> This is my text number 2 </font>_x000D_
 _x000D_
 <font size="3"> This is my text number 3</font> _x000D_
 _x000D_
 <font size="4"> This is my text number 4</font> _x000D_
 _x000D_
 <font size="5"> This is my text number 5</font> _x000D_
 _x000D_
 <font size="6"> This is my text number 6</font>

A better alternative to MinGW is bash for powershell. You can install bash for Windows 10 using the steps given here

After you've installed bash, all you've got to do is run the bash command on your terminal.

user@HP:/mnt/f/cpp$ ./program

Following is the util function to get current timestamp in milliseconds:

#include <sys/time.h>

long long current_timestamp() {
    struct timeval te; 
    gettimeofday(&te, NULL); // get current time
    long long milliseconds = te.tv_sec*1000LL + te.tv_usec/1000; // calculate milliseconds
    // printf("milliseconds: %lld\n", milliseconds);
    return milliseconds;
}

About timezone:

gettimeofday() support to specify timezone, I use NULL, which ignore the timezone, but you can specify a timezone, if need.

@Update - timezone

Since the long representation of time is not relevant to or effected by timezone itself, so setting tz param of gettimeofday() is not necessary, since it won't make any difference.

And, according to man page of gettimeofday(), the use of the timezone structure is obsolete, thus the tz argument should normally be specified as NULL, for details please check the man page.

MySQLi stands for MySQL improved. It's an object-oriented interface to the MySQL bindings which makes things easier to use. It also offers support for prepared statements (which are very useful). If you're on PHP 5 use MySQLi.

Simply put the path in double quotes in front of cd, Like this:

cd "C:\Users\MyComputer\Documents\Visual Studio 2019\Projects"

What you are describing is a change of state in the parent. You pass that to the child via a prop. As you suggested, you would watch that prop. When the child takes action, it notifies the parent via an emit, and the parent might then change the state again.

var Child = {_x000D_
  template: '<div>{{counter}}</div>',_x000D_
  props: ['canI'],_x000D_
  data: function () {_x000D_
    return {_x000D_
      counter: 0_x000D_
    };_x000D_
  },_x000D_
  watch: {_x000D_
    canI: function () {_x000D_
      if (this.canI) {_x000D_
        ++this.counter;_x000D_
        this.$emit('increment');_x000D_
      }_x000D_
    }_x000D_
  }_x000D_
}_x000D_
new Vue({_x000D_
  el: '#app',_x000D_
  components: {_x000D_
    'my-component': Child_x000D_
  },_x000D_
  data: {_x000D_
    childState: false_x000D_
  },_x000D_
  methods: {_x000D_
    permitChild: function () {_x000D_
      this.childState = true;_x000D_
    },_x000D_
    lockChild: function () {_x000D_
      this.childState = false;_x000D_
    }_x000D_
  }_x000D_
})

<script src="//cdnjs.cloudflare.com/ajax/libs/vue/2.2.1/vue.js"></script>_x000D_
<div id="app">_x000D_
<my-component :can-I="childState" v-on:increment="lockChild"></my-component>_x000D_
<button @click="permitChild">Go</button>_x000D_
</div>

If you truly want to pass events to a child, you can do that by creating a bus (which is just a Vue instance) and passing it to the child as a prop.

this is the exact usage:

ssh -v -i [yourkeypairfile] ec2-user@[yourdnsaddress]

above example was taken directly from the AWS tutorial for connecting to a Linux/UNIX machine at: http://docs.amazonwebservices.com/AWSEC2/latest/GettingStartedGuide/

Navigation Bar:

navigationController?.navigationBar.barTintColor = UIColor.green

Replace greenColor with whatever UIColor you want, you can use an RGB too if you prefer.

Navigation Bar Text:

navigationController?.navigationBar.titleTextAttributes = [.foregroundColor: UIColor.orange]

Replace orangeColor with whatever color you like.

Tab Bar:

tabBarController?.tabBar.barTintColor = UIColor.brown

Tab Bar Text:

tabBarController?.tabBar.tintColor = UIColor.yellow

On the last two, replace brownColor and yellowColor with the color of your choice.

It's a reserved keyword (like return, filter, function, break).

But what happens when you want a script to exit from within a function defined in that script? ... To make this easier, Powershell has the exit keyword.

Of course, as other have pointed out, it's not hard to do what you want by wrapping exit in a function:

My solutions in one of my own sites, with a table:

$.getJSON("sections/view_numbers_update.php", function(data) {
 $.each(data, function(index, objNumber) {
  $('#tr_' + objNumber.intID).find("td").eq(3).html(objNumber.datLastCalled);
  $('#tr_' + objNumber.intID).find("td").eq(4).html(objNumber.strStatus);
  $('#tr_' + objNumber.intID).find("td").eq(5).html(objNumber.intDuration);
  $('#tr_' + objNumber.intID).find("td").eq(6).html(objNumber.blnWasHuman);
 });
});

sections/view_numbers_update.php Returns something like:

[{"intID":"19","datLastCalled":"Thu, 10 Jan 13 08:52:20 +0000","strStatus":"Completed","intDuration":"0:04 secs","blnWasHuman":"Yes","datModified":1357807940},
{"intID":"22","datLastCalled":"Thu, 10 Jan 13 08:54:43 +0000","strStatus":"Completed","intDuration":"0:00 secs","blnWasHuman":"Yes","datModified":1357808079}]

HTML table:

<table id="table_numbers">
 <tr>
  <th>[...]</th>
  <th>[...]</th>
  <th>[...]</th>
  <th>Last Call</th>
  <th>Status</th>
  <th>Duration</th>
  <th>Human?</th>
  <th>[...]</th>
 </tr>
 <tr id="tr_123456">
  [...]
 </tr>
</table>

This essentially gives every row a unique id preceding with 'tr_' to allow for other numbered element ids, at server script time. The jQuery script then just gets this TR_[id] element, and fills the correct indexed cell with the json return.

The advantage is you could get the complete array from the DB, and either foreach($array as $record) to create the table html, OR (if there is an update request) you can die(json_encode($array)) before displaying the table, all in the same page, but same display code.

var test = scala.collection.mutable.Map.empty[String, String]

So yes, you should prefer the shadowPath property for performance, but also: From the header file of CALayer.shadowPath

Specifying the path explicitly using this property will usually * improve rendering performance, as will sharing the same path * reference across multiple layers

A lesser known trick is sharing the same reference across multiple layers. Of course they have to use the same shape, but this is common with table/collection view cells.

I don't know why it gets faster if you share instances, i'm guessing it caches the rendering of the shadow and can reuse it for other instances in the view. I wonder if this is even faster with

Maybe you have changed the namespace in your project!
There is a table in your data base called dbo.__MigrationHistory. The table has a column called ContextKey.
The value of this column is based on your namespace. for example is "DataAccess.Migrations.Configuration".
When you change the namespace, it causes duplicate table names with different namespaces.
So, after you change namespace in code side, change the namespace in this table in database, too, (for all rows).
For example, if you change the namespace to EFDataAccess, then you should change the values of ContextKey column in dbo.__MigrationHistory to "EFDataAccess.Migrations.Configuration".
Then in code side, in Tools => Package Manager Console, use the update-database command.

Another option instead of changing the context value in the database is to hard code the context value in your code to the old namespace value. This is possible by inheriting DbMigrationsConfiguration<YourDbContext> and in the constructor just assign the old context value to ContextKey, than inherit from MigrateDatabaseToLatestVersion<YourDbContext, YourDbMigrationConfiguration> and leave that class empty. The last thing to do is call Database.SetInitializer(new YourDbInitializer()); in your DbContext in a static constructor.

I hope your problem will be fixed.

I've tried the above methods, end the adb process through task manager and all, it didn't work. But when I ran the adb.exe file as admin it worked fine.

To clear the value you can always reset it to $Null. For example:

Set-Mailbox -Identity "username" -CustomAttribute1 $Null

I'm not a fan of any of these solutions. I use this instead:

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "https://www.google.com/recaptcha/api/siteverify");
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, [
    'secret' => $privatekey,
    'response' => $_POST['g-recaptcha-response'],
    'remoteip' => $_SERVER['REMOTE_ADDR']
]);

$resp = json_decode(curl_exec($ch));
curl_close($ch);

if ($resp->success) {
    // Success
} else {
    // failure
}

I'd argue that this is superior because you ensure it is being POSTed to the server and it's not making an awkward 'file_get_contents' call. This is compatible with recaptcha 2.0 described here: https://developers.google.com/recaptcha/docs/verify

I find this cleaner. I see most solutions are file_get_contents, when I feel curl would suffice.

android.view.InflateException: Binary XML file line #16: Error inflating class com.google.android.material.bottomappbar.BottomAppBar

The view can be anything that is failing to get inflated, this kind of error comes when there is a clash in resolving the class names or name attribute of a view referred in the XML file.

When I get the same error I just got everything clean and safe in UI-XML file, the view I was using,

   <com.google.android.material.bottomappbar.BottomAppBar
    android:id="@+id/bottomAppBar"
    style="@style/Widget.MaterialComponents.BottomAppBar.Colored"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_gravity="bottom"
    app:hideOnScroll="true"
    app:menu="@menu/bottom_app_bar"
    app:navigationIcon="@drawable/ic__menu_24"/>

I was using a style attribute which was referring the Material components property. But my styles.xml had...

<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
....
</style>

Where the class resolving was facing the conflict. My view attributes referred a property that was not defined in my app theme. The right parent theme from material components helped me. So I changed the parent attribute to...

<style name="AppTheme" parent="Theme.MaterialComponents.Light.NoActionBar">
...
</style>

Which resolved the issue.

If a value contains a comma, a newline character or a double quote, then the string must be enclosed in double quotes. E.g: "Newline char in this field \n".

The issue is two-fold:

1. WordPress reformats the YouTube link
2. You need a custom embed link to support a live stream embed

As a prerequisite (as of August, 2016), you need to link an AdSense account and then turn on monetization in your YouTube channel. It's a painful change that broke a lot of live streams.

You will need to use the following URL format for the embed:

<iframe width="560" height="315" src="https://www.youtube.com/embed/live_stream?channel=CHANNEL_ID&autoplay=1" frameborder="0" allowfullscreen></iframe>

The &autoplay=1 is not necessary, but I like to include it. Change CHANNEL to your channel's ID. One thing to note is that WordPress may reformat the URL once you commit your change. Therefore, you'll need a plugin that allows you to use raw code and not have it override. Using a custom PHP code plugin can help and you would just echo the code like so:

<?php echo '<iframe width="560" height="315" src="https://www.youtube.com/embed/live_stream?channel=CHANNEL_ID&autoplay=1" frameborder="0" allowfullscreen></iframe>'; ?>

Let me know if that worked for you!

While string interpolation will work, as your question specifies rails 4, you could be using Arel for this and keeping your app database agnostic.

def self.search(query, page=1)
  query = "%#{query}%"
  name_match = arel_table[:name].matches(query)
  postal_match = arel_table[:postal_code].matches(query)
  where(name_match.or(postal_match)).page(page).per_page(5)
end

I've found the solution in this thread

@(ViewContext.RouteData.Values["parameterName"])

I know that it may be not directly answer to your question, because you said that null values have to be supported.

But I just want to note that supporting nulls in compareTo is not in line with compareTo contract described in official javadocs for Comparable:

Note that null is not an instance of any class, and e.compareTo(null) should throw a NullPointerException even though e.equals(null) returns false.

So I would either throw NullPointerException explicitly or just let it be thrown first time when null argument is being dereferenced.

While it's good to read and understand Josh's answer, you'll probably be happier using the class Microsoft provided for this purpose: System.Collections.BitArray It's available in all versions of .NET Framework.

I suggest Freewall. It is a cross-browser and responsive jQuery plugin to help you create many types of grid layouts: flexible layouts, images layouts, nested grid layouts, metro style layouts, pinterest like layouts ... with nice CSS3 animation effects and call back events. Freewall is all-in-one solution for creating dynamic grid layouts for desktop, mobile, and tablet.

You could do this manually or using IndexOf method.

Manually:

int index = 43;
string piece = myString.Substring(index);

Using IndexOf you can see where the fullstop is:

int index = myString.IndexOf(".") + 1;
string piece = myString.Substring(index);

I had a similar issue with mongoose :

fields: 
    [ '[object Object]',
     '[object Object]',
     '[object Object]',
     '[object Object]' ] }

In fact, I was using "type" as a property name in my schema :

fields: [
    {
      name: String,
      type: {
        type: String
      },
      registrationEnabled: Boolean,
      checkinEnabled: Boolean
    }
  ]

To avoid that behavior, you have to change the parameter to :

fields: [
    {
      name: String,
      type: {
        type: { type: String }
      },
      registrationEnabled: Boolean,
      checkinEnabled: Boolean
    }
  ]

The previous answers were in the right track, but the complete answer for this is going to Disabling rules only for a group of files, there you'll find the documentation needed to disable/enable rules for certain folders (Because in some cases you don't want to ignore the whole thing, only disable certain rules). Example:

{
    "env": {},
    "extends": [],
    "parser": "",
    "plugins": [],
    "rules": {},
    "overrides": [
      {
        "files": ["test/*.spec.js"], // Or *.test.js
        "rules": {
          "require-jsdoc": "off"
        }
      }
    ],
    "settings": {}
}

in code

listView.setSelector(getResources().getDrawable(R.drawable.transparent));

and add small transparent image to drawable folder.

Like: transparent.xml

<?xml version="1.0" encoding="utf-8"?>    
<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <solid android:color="#00000000"/>
</shape>

import xml.dom.minidom

file = open("./content.xml", 'r')
xml_string = file.read()
file.close()

parsed_xml = xml.dom.minidom.parseString(xml_string)
pretty_xml_as_string = parsed_xml.toprettyxml()

file = open("./content_new.xml", 'w')
file.write(pretty_xml_as_string)
file.close()

If you want to do this, you need to save it in a variable first. So you don't need to use id to query this element every time.

var el = $("#page_navigation1");

$("#add").click(function(){
  el.attr("id","page_navigation1");
});     

$("#remove").click(function(){
  el.removeAttr("id");
});

I know this is quite an old post, but I would like to point out the following for people who will read it in the future: As per MS:

Do not use the IISReset.exe tool to restart the IIS services. Instead, use the NET STOP and NET START commands. For example, to stop and start the World Wide Web Publishing Service, run the following commands:

• NET STOP iisadmin /y
• NET START w3svc

There are two benefits to using the NET STOP/NET START commands to restart the IIS Services as opposed to using the IISReset.exe tool. First, it is possible for IIS configuration changes that are in the process of being saved when the IISReset.exe command is run to be lost. Second, using IISReset.exe can make it difficult to identify which dependent service or services failed to stop when this problem occurs. Using the NET STOP commands to stop each individual dependent service will allow you to identify which service fails to stop, so you can then troubleshoot its failure accordingly.

Inventing yet another version of the wheel...

This function is a (hopefully) POSIX-compatible plain bourne shell replacement for GNU getopt. It supports short/long options which can accept mandatory/optional/no arguments, and the way in which options are specified is almost identical to GNU getopt, so conversion is trivial.

Of course this is still a sizeable chunk of code to drop into a script, but it's about half the lines of the well-known getopt_long shell function, and might be preferable in cases where you just want to replace existing GNU getopt uses.

This is pretty new code, so YMMV (and definitely please let me know if this isn't actually POSIX-compatible for any reason -- portability was the intention from the outset, but I don't have a useful POSIX test environment).

Look at this example:

public void RunWorker()
{
    Thread newThread = new Thread(WorkerMethod);
    newThread.Start(new Parameter());
}

public void WorkerMethod(object parameterObj)
{
    var parameter = (Parameter)parameterObj;
    // do your job!
}

You are first creating a thread by passing delegate to worker method and then starts it with a Thread.Start method which takes your object as parameter.

So in your case you should use it like this:

    Thread thread = new Thread(download);
    thread.Start(filename);

But your 'download' method still needs to take object, not string as a parameter. You can cast it to string in your method body.

Here is a summary.

1. escape() will not encode @ * _ + - . /

   Do not use it.

2. encodeURI() will not encode A-Z a-z 0-9 ; , / ? : @ & = + $ - _ . ! ~ * ' ( ) #

   Use it when your input is a complete URL like 'https://searchexample.com/search?q=wiki'

3. encodeURIComponent() will not encode A-Z a-z 0-9 - _ . ! ~ * ' ( ) Use it when your input is part of a complete URL e.g const queryStr = encodeURIComponent(someString)

Just in case it helps someone, since these questions (and answers) helped me really much; I decided to create an alias that runs these 4 commands in a row:

Just add the following line to your ~/.bashrc file (modify the main keyword accordingly to the name of your .tex and .bib files)

alias texbib = 'pdflatex main.tex && bibtex main && pdflatex main.tex && pdflatex main.tex'

And now, by just executing the texbib command (alias), all these commands will be executed sequentially.

if True:
    print "true"

This always happens because True is always True.

You want something like this:

if check():
    print "true"
else:
    print "false"

Good luck!
