This can also happen (for cross-origin requests only) because of a new feature called site isolation

This page details the issue and a work-around. Which is to go to chrome://flags/#site-isolation-trial-opt-out in chrome and change that setting to "Opt-out" and reload chrome.

It's a known issue. However that page says it's fixed in chrome 68, but I'm running chrome 68 and I still have the issue.

    List<int> first_list = new List<int>() {
        1,

    var result = first_list.Union(second_list);

As well as the previous answers are you could always use the Pull attrib as well:

    <ol class="row" id="possibilities">
       <li class="span6">
         <div class="row">
           <div class="span3">
             <p>some text here</p>
             <p>Text Here too</p>
           </div>
         <figure class="span3 pull-right"><img src="img/screenshots/options.png" alt="Some text" /></figure>
        </div>
 </li>
 <li class="span6">
     <div class="row">
         <figure class="span3"><img src="img/qrcode.png" alt="Some text" /></figure>
         <div class="span3">
             <p>Some text</p>
             <p>Some text here too.</p>
         </div>
     </div>

Here is a good introduction to logging in Java: http://www.javapractices.com/topic/TopicAction.do?Id=143

Java comes with a logging API since it's 1.4.2 version: http://download.oracle.com/javase/1.4.2/docs/guide/util/logging/overview.html

You can also use other logging frameworks like Apache Log4j which is the most popular one: http://logging.apache.org/log4j

I suggest you to use a logging abstraction framework which allows you to change your logging framework without re-factoring you code. So you can starts by using Jul (Java Util Logging) then swith to Log4j without changing you code. The most popular logging facade is slf4j: http://www.slf4j.org/

I second Jon Skeet's answer and want to add the following links for everyone who want to know more about "volatile" and Interlocked:

With regard to Peter Lawrey's note that you don't need instanceof for final classes and can just use a reference equality, be careful! Even though the final classes cannot be extended, they are not guaranteed to be loaded by the same classloader. Only use x.getClass() == SomeFinal.class or its ilk if you are absolutely positive that there is only one classloader in play for that section of code.

I'm sure you have your reasons, but just in case... you should also consider using a "merge" query instead:

begin
    merge into some_table st
    using (select 'some' name, 'values' value from dual) v
    on (st.name=v.name)
    when matched then update set st.value=v.value
    when not matched then insert (name, value) values (v.name, v.value);
end;

(modified the above to be in the begin/end block; obviously you can run it independantly of the procedure too).

The answers to your two questions are related. I'll start with the second:

Once you have staged a file (often with git add, though some other commands implicitly stage the changes as well, like git rm) you can back out that change with git reset -- <file>.

In your case you must have used git rm to remove the file, which is equivalent to simply removing it with rm and then staging that change. If you first unstage it with git reset -- <file> you can then recover it with git checkout -- <file>.

#include? should work, it works for general objects, not only strings. Your problem in example code is this test:

unless @suggested_horses.exists?(horse.id)
  @suggested_horses<< horse
end

(even assuming using #include?). You try to search for specific object, not for id. So it should be like this:

unless @suggested_horses.include?(horse)
  @suggested_horses << horse
end

ActiveRecord has redefined comparision operator for objects to take a look only for its state (new/created) and id

Just make sure it is executable, using chmod +x. By default, the current directory is not on your PATH, so you will need to execute it as ./script.sh - or otherwise reference it by a qualified path. Alternatively, if you truly need just script.sh, you would need to add it to your PATH. (You may not have access to modify the system path, but you can almost certainly modify the PATH of your own current environment.) This also assumes that your script starts with something like #!/bin/sh.

You could also still use an alias, which is not really related to shell scripting but just the shell, and is simple as:

alias script.sh='sh script.sh'

Which would allow you to use just simply script.sh (literally - this won't work for any other *.sh file) instead of sh script.sh.

That means you must install simplejson. On newer versions of python, it was included by default into python's distribution, and renamed to json. So if you are on python 2.6+ you should change all instances of simplejson to json.

For a quick fix you could also edit the file and change the line:

import simplejson

to:

import json as simplejson

and hopefully things will work.

The answer is good, but for the people that want this with range(), the form to do is:

range(end):

>>> list(range(10))
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9]

range(start,end):

 >>> list(range(1, 11))
[1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

range(start,end, step):

 >>> list(range(0, 30, 5))
[0, 5, 10, 15, 20, 25]

These are applicable to MacOS Sierra 10.12.5 (16F73) and probably some other recent and upcoming versions of MacOS.

1. chsh is not enough to change the default shell. Make sure you press Command+, while your terminal is open and change the 'Shells open with' option to 'Default login shell.'

2. In case of bash, make sure that you execute echo $BASH_VERSION to confirm you are running the intended version of bash. bash --version does not give you correct information.

I was trying to publish my own package and then include it in another project. I had that issue because of how I've built the first module. Im using ES2015 export to create the module, e.g lets say the module looks like that:

export default function(who = 'world'){
    return `Hello ${who}`;
}

After compiled with Babel and before been published:

'use strict';

Object.defineProperty(exports, "__esModule", {
    value: true
});

exports.default = function () {
    var who = arguments.length <= 0 || arguments[0] === undefined ? 'world' : arguments[0];


    return 'Hello ' + who;
};

So after npm install module-name in another project (none ES2015) i had to do

var hello = require('module-name').default;

To actually got the package imported.

Hope that helps!

find location -ctime time_period

Examples of time_period:

• More than 30 days ago: -ctime +30

• Less than 30 days ago: -ctime -30

• Exactly 30 days ago: -ctime 30

You can find Module Pattern JavaScript here http://www.sga.su/module-pattern-javascript/

It is worth noting that sometimes you do want non-configurable "hard-coded" numbers in your code. There are a number of famous ones including 0x5F3759DF which is used in the optimized inverse square root algorithm.

In the rare cases where I find the need to use such Magic Numbers, I set them as a const in my code, and document why they are used, how they work, and where they came from.

I am looking for this kind of solution for my self as well. I found reference in terms aggregation.

So, according to that following is the proper solution.

{
"aggs" : {
    "langs" : {
        "terms" : { "field" : "language",  
                    "size" : 500 }
    }
}}

But if you ran into following error:

"error": {
        "root_cause": [
            {
                "type": "illegal_argument_exception",
                "reason": "Fielddata is disabled on text fields by default. Set fielddata=true on [fastest_method] in order to load fielddata in memory by uninverting the inverted index. Note that this can however use significant memory. Alternatively use a keyword field instead."
            }
        ]}

In that case, you have to add "KEYWORD" in the request, like following:

   {
    "aggs" : {
        "langs" : {
            "terms" : { "field" : "language.keyword",  
                        "size" : 500 }
        }
    }}

For me just using the Integer.toString() method works for me just fine. You can convert it over if you just want to very if it is null. Example below:

private void setCarColor(int redIn, int blueIn, int greenIn)
{
//Integer s = null;
if (Integer.toString(redIn) == null || Integer.toString(blueIn) == null ||     Integer.toString(greenIn) == null )

you can also add below code in AndroidManifest.xml.

android:icon="@android:color/transparent"

It will work fine.

But I found that this gives a problem as the launcher icon also become transparent.

So I used:

getActionBar().setIcon(new ColorDrawable(getResources().getColor(android.R.color.transparent)));

and it worked fine.

But if you are having more than one activity and want to make the icon on an activity transparent then the previous approach will work.

First, the signature of your data() function:

bool data(struct *sampleData)

cannot possibly work, because the argument lacks a name. When you declare a function argument that you intend to actually access, it needs a name. So change it to something like:

bool data(struct sampleData *samples)

But in C++, you don't need to use struct at all actually. So this can simply become:

bool data(sampleData *samples)

Second, the sampleData struct is not known to data() at that point. So you should declare it before that:

struct sampleData {
    int N;
    int M;
    string sample_name;
    string speaker;
};

bool data(sampleData *samples)
{
    samples->N = 10;
    samples->M = 20;
    // etc.
}

And finally, you need to create a variable of type sampleData. For example, in your main() function:

int main(int argc, char *argv[]) {
    sampleData samples;
    data(&samples);
}

Note that you need to pass the address of the variable to the data() function, since it accepts a pointer.

However, note that in C++ you can directly pass arguments by reference and don't need to "emulate" it with pointers. You can do this instead:

// Note that the argument is taken by reference (the "&" in front
// of the argument name.)
bool data(sampleData &samples)
{
    samples.N = 10;
    samples.M = 20;
    // etc.
}

int main(int argc, char *argv[]) {
    sampleData samples;

    // No need to pass a pointer here, since data() takes the
    // passed argument by reference.
    data(samples);
}

This kind of thing doesn't just magically happen on its own; you changed something! In industry we use version control to make regular savepoints, so when something goes wrong we can trace back the specific changes we made that resulted in that problem.

Since you haven't done that here, we can only really guess. In Visual Studio, Intellisense (the technology that gives you auto-complete dropdowns and those squiggly red lines) works separately from the actual C++ compiler under the bonnet, and sometimes gets things a bit wrong.

In this case I'd ask why you're including both cstdlib and stdlib.h; you should only use one of them, and I recommend the former. They are basically the same header, a C header, but cstdlib puts them in the namespace std in order to "C++-ise" them. In theory, including both wouldn't conflict but, well, this is Microsoft we're talking about. Their C++ toolchain sometimes leaves something to be desired. Any time the Intellisense disagrees with the compiler has to be considered a bug, whichever way you look at it!

Anyway, your use of using namespace std (which I would recommend against, in future) means that std::system from cstdlib now conflicts with system from stdlib.h. I can't explain what's going on with std::cout and std::cin.

Try removing #include <stdlib.h> and see what happens.

If your program is building successfully then you don't need to worry too much about this, but I can imagine the false positives being annoying when you're working in your IDE.

Srsly guys... Why so many lines of code for a simple method like this? Here's my solution:

def isPrime(a):
    div = a - 1
    res = True
    while(div > 1):
        if a % div == 0:
            res = False
        div = div - 1
    return res

Simple solution on my server: After migrating to a new Debian 7 server with my MySQL databases, the second local IP address, 127.0.1.1, was missing in my hosts file. Adding this resolved the warnings:

echo -e "\n127.0.1.1       $(hostname)" >> /etc/hosts

You would have to open a new window(or navigate to a new page) containing just the information you wish the user to be able to print

Javscript:

function printInfo(ele) {
    var openWindow = window.open("", "title", "attributes");
    openWindow.document.write(ele.previousSibling.innerHTML);
    openWindow.document.close();
    openWindow.focus();
    openWindow.print();
    openWindow.close();
}

HTML:

<div id="....">
    <div>
        content to print
    </div><a href="#" onclick="printInfo(this)">Print</a>
</div>

A few notes here: the anchor must NOT have whitespace between it and the div containing the content to print

select this_.code from true.employee this_ where this_.code=? is what will be sent to your database.

this_ is an alias for that instance of the employee table.

the above solutions wont work on ipad-2

recently I had an safari browser crash issue while plotting the markers even if there are less number of markers. Initially I was using marker with label (markerwithlabel.js) library for plotting the marker , when i use google native marker it was working fine even with large number of markers but i want customized markers , so i refer the above solution given by jonathan but still the crashing issue is not resolved after doing lot of research i came to know about http://nickjohnson.com/b/google-maps-v3-how-to-quickly-add-many-markers this blog and now my map search is working smoothly on ipad-2 :)

You can try cactoos for that.

final InputStream input = new InputStreamOf("example");

The object is created with new and not a static method for a reason.

Use this SimpleDateFormat formatDate = new SimpleDateFormat("hh:mm a");

Java docs for SimpleDateFormat

single/double quotes and backslash everywhere:

$ python -c 'exec("import sys\nfor i in range(10): print \"bob\"")'

Much better:

$ python -c '
> import sys
> for i in range(10):
>   print "bob"
> '

@System.Configuration.ConfigurationManager.AppSettings["myKey"]

Facebook seemingly randomly disables the ability to set localhost as a domain on your facebook app. I found the easiest work around was to tunnel my localhost to the web. This can be done for free using http://progrium.com/localtunnel/ or with a custom url (easier since you don't have to change url everytime in facebook) https://showoff.io

If possible - use visibility instead of display

For instance:

.child {
    visibility: hidden;
    opacity: 0;
    transition: opacity 0.3s, visibility 0.3s;
}

.parent:hover .child {
    visibility: visible;
    opacity: 1;
    transition: opacity 0.3s, visibility 0.3s;
}

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".

You can use below online tool to escape "" and , operators. https://www.freeformatter.com/csv-escape.html#ad-output

Another solution, you can solve your problem using replaceAll with some regex ^.{1} (regex demo) for example :

String str = "Jamaica";
int nbr = 1;
str = str.replaceAll("^.{" + nbr + "}", "");//Output = amaica

std::copy (b.begin(), b.end(), std::back_inserter(a));

This can be used in case the items in vector a have no assignment operator (e.g. const member).

In all other cases this solution is ineffiecent compared to the above insert solution.

You can create a character array which includes all the letters and numbers, and then you can randomly select from this character array and create your own string password.

char[] chars = new char[62]; // Sum of letters and numbers

int i = 0;

for(char c = 'a'; c <= 'z'; c++) { // For letters
    chars[i++] = c;
}

for(char c = '0'; c <= '9';c++) { // For numbers
    chars[i++] = c;
}

for(char c = 'A'; c <= 'Z';c++) { // For capital letters
    chars[i++] = c;
}

int numberOfCodes = 0;
String code = "";
while (numberOfCodes < 1) { // Enter how much you want to generate at one time
    int numChars = 8; // Enter how many digits you want in your password

    for(i = 0; i < numChars; i++) {
        char c = chars[(int)(Math.random() * chars.length)];
        code = code + c;
    }
    System.out.println("Code is:" + code);
}

for the sake of completeness, you could use:

(DT_STR,8, 1252) (YEAR(GetDate()) * 10000 + MONTH(GetDate()) * 100 + DAY(GetDate()))

for YYYYMMDD or

RIGHT("000000" + (DT_STR,8, 1252) (DAY(GetDate()) * 1000000 + MONTH(GetDate()) * 10000 + YEAR(GetDate())), 8)

for DDMMYYYY (without hyphens). If you want / need the date as integer (e.g. for _key-columns in DWHs), just remove the DT_STR / RIGTH function and do just the math.

The problem with iPhone camera is that the first models (of which there are tons in use) have a fixed-focus camera that cannot take picture in-focus for distances under 2ft. The images are blurry and distorted and if taken from greater distance there is not enough detail/information from the barcode.

A few companies have developed iPhone apps that can accomodate for that by using advanced de-blurring technologies. Those applications you can find on Apple app store: pic2shop, RedLaser and ShopSavvy. All of the companies have announced that they have also SDKs available - some for free or very preferential terms, check that one out.

I have noticed that no answer display an image with a single legend referencing many curves in different subplots, so I have to show you one... to make you curious...

Now, you want to look at the code, don't you?

from numpy import linspace
import matplotlib.pyplot as plt

# Calling the axes.prop_cycle returns an itertoools.cycle

color_cycle = plt.rcParams['axes.prop_cycle']()

# I need some curves to plot

x = linspace(0, 1, 51)
f1 = x*(1-x)   ; lab1 = 'x - x x'
f2 = 0.25-f1   ; lab2 = '1/4 - x + x x' 
f3 = x*x*(1-x) ; lab3 = 'x x - x x x'
f4 = 0.25-f3   ; lab4 = '1/4 - x x + x x x'

# let's plot our curves (note the use of color cycle, otherwise the curves colors in
# the two subplots will be repeated and a single legend becomes difficult to read)
fig, (a13, a24) = plt.subplots(2)

a13.plot(x, f1, label=lab1, **next(color_cycle))
a13.plot(x, f3, label=lab3, **next(color_cycle))
a24.plot(x, f2, label=lab2, **next(color_cycle))
a24.plot(x, f4, label=lab4, **next(color_cycle))

# so far so good, now the trick

lines_labels = [ax.get_legend_handles_labels() for ax in fig.axes]
lines, labels = [sum(lol, []) for lol in zip(*lines_labels)]

# finally we invoke the legend (that you probably would like to customize...)

fig.legend(lines, labels)
plt.show()

The two lines

lines_labels = [ax.get_legend_handles_labels() for ax in fig.axes]
lines, labels = [sum(lol, []) for lol in zip(*lines_labels)]

deserve an explanation — to this aim I have encapsulated the tricky part in a function, just 4 lines of code but heavily commented

def fig_legend(fig, **kwdargs):

    # generate a sequence of tuples, each contains
    #  - a list of handles (lohand) and
    #  - a list of labels (lolbl)
    tuples_lohand_lolbl = (ax.get_legend_handles_labels() for ax in fig.axes)
    # e.g. a figure with two axes, ax0 with two curves, ax1 with one curve
    # yields:   ([ax0h0, ax0h1], [ax0l0, ax0l1]) and ([ax1h0], [ax1l0])
    
    # legend needs a list of handles and a list of labels, 
    # so our first step is to transpose our data,
    # generating two tuples of lists of homogeneous stuff(tolohs), i.e
    # we yield ([ax0h0, ax0h1], [ax1h0]) and ([ax0l0, ax0l1], [ax1l0])
    tolohs = zip(*tuples_lohand_lolbl)

    # finally we need to concatenate the individual lists in the two
    # lists of lists: [ax0h0, ax0h1, ax1h0] and [ax0l0, ax0l1, ax1l0]
    # a possible solution is to sum the sublists - we use unpacking
    handles, labels = (sum(list_of_lists, []) for list_of_lists in tolohs)

    # call fig.legend with the keyword arguments, return the legend object

    return fig.legend(handles, labels, **kwdargs)

PS I recognize that sum(list_of_lists, []) is a really inefficient method to flatten a list of lists but ? I love its compactness, ? usually is a few curves in a few subplots and ? Matplotlib and efficiency? ;-)

Important Update

If you want to stick with the official Matplotlib API my answer above is perfect, really.

On the other hand, if you don't mind using a private method of the matplotlib.legend module ... it's really much much much easier

from matplotlib.legend import _get_legend_handles_labels
...

fig.legend(*_get_legend_handles_and_labels(fig.axes), ...)

A complete explanation can be found in the source code of Axes.get_legend_handles_labels in .../matplotlib/axes/_axes.py

Iam confused a lot from morning whether it should be less than or greater than`

this can accept value less than "99999"

I think you answered it yourself... But it's valid when it's less than. Thus the following is incorrect:

}elseif($("#seats").val() < 99999){
  alert("Not a valid Number");
}else{

You are saying if it's less than 99999, then it's not valid. You want to do the opposite:

}elseif($("#seats").val() >= 99999){
  alert("Not a valid Number");
}else{

Also, since you have $("#seats") twice, jQuery has to search the DOM twice. You should really be storing the value, or at least the DOM element in a variable. And some more of your code doesn't make much sense, so I'm going to make some assumptions and put it all together:

var seats = $("#seats").val();

var error = null;

if (seats == "") {
    error = "Number is required";
} else {
    var seatsNum = parseInt(seats);
    
    if (isNaN(seatsNum)) {
        error = "Not a valid number";
    } else if (seatsNum >= 99999) {
        error = "Number must be less than 99999";
    }
}

if (error != null) {
    alert(error);
} else {
    alert("Valid number");
}

// If you really need setflag:
var setflag = error != null;

Here's a working sample: http://jsfiddle.net/LUY8q/

I wouldn't recommend doing this, but you can override the ngClick directive to do what you are looking for. That's not saying, you should.

With the original implementation in mind:

compile: function($element, attr) {
  var fn = $parse(attr[directiveName]);
  return function(scope, element, attr) {
    element.on(lowercase(name), function(event) {
      scope.$apply(function() {
        fn(scope, {$event:event});
      });
    });
  };
}

We can do this to override it:

// Go into your config block and inject $provide.
app.config(function ($provide) {

  // Decorate the ngClick directive.
  $provide.decorator('ngClickDirective', function ($delegate) {

    // Grab the actual directive from the returned $delegate array.
    var directive = $delegate[0];

    // Stow away the original compile function of the ngClick directive.
    var origCompile = directive.compile;

    // Overwrite the original compile function.
    directive.compile = function (el, attrs) {

      // Apply the original compile function. 
      origCompile.apply(this, arguments);

      // Return a new link function with our custom behaviour.
      return function (scope, el, attrs) {

        // Get the name of the passed in function. 
        var fn = attrs.ngClick;

        el.on('click', function (event) {
          scope.$apply(function () {

            // If no property on scope matches the passed in fn, return. 
            if (!scope[fn]) {
              return;
            }

            // Throw an error if we misused the new ngClick directive.
            if (typeof scope[fn] !== 'function') {
              throw new Error('Property ' + fn + ' is not a function on ' + scope);
            }

            // Call the passed in function with the event.
            scope[fn].call(null, event);

          });
        });          
      };
    };    

    return $delegate;
  });
});

Then you'd pass in your functions like this:

<div ng-click="func"></div>

as opposed to:

<div ng-click="func()"></div>

Like I said, I would not recommend doing this but it's a proof of concept showing you that, yes - you can in fact overwrite/extend/augment the builtin angular behaviour to fit your needs. Without having to dig all that deep into the original implementation.

Do please use it with care, if you were to decide on going down this path (it's a lot of fun though).

This is a bit late, but I just stumbled on this problem, trying to resolve my own problem of this kind. I then realized that I had this line in the ajax post wrong:

data: "{'quantity' : " + total_qty + ",'itemId':" + itemId + "}",

It should be:

data: "{quantity : '" + total_qty + "',itemId: '" + itemId + "'}",

As well as the WebMethod to:

public static string AddTo_Cart(string quantity, string itemId)

And this resolved my problem.

Hope it may be of help to someone else as well.

The file is just a file, you need to create an image like so:

var _URL = window.URL || window.webkitURL;
$("#file").change(function (e) {
    var file, img;
    if ((file = this.files[0])) {
        img = new Image();
        var objectUrl = _URL.createObjectURL(file);
        img.onload = function () {
            alert(this.width + " " + this.height);
            _URL.revokeObjectURL(objectUrl);
        };
        img.src = objectUrl;
    }
});

Demo: http://jsfiddle.net/4N6D9/1/

I take it you realize this is only supported in a few browsers. Mostly firefox and chrome, could be opera as well by now.

P.S. The URL.createObjectURL() method has been removed from the MediaStream interface. This method has been deprecated in 2013 and superseded by assigning streams to HTMLMediaElement.srcObject. The old method was removed because it is less safe, requiring a call to URL.revokeOjbectURL() to end the stream. Other user agents have either deprecated (Firefox) or removed (Safari) this feature feature.

If you install using bundler as suggested by gryzzly and the gem creates a binary then make sure you run it with bundle exec mygembinary as the gem is stored in a bundler directory which is not visible on the normal gem path.

For commenting blocks of code, I like the NERD Commenter plugin.

Select some text:

Shift-V
...select the lines of text you want to comment....

Comment:

,cc

Uncomment:

,cu

Or just toggle the comment state of a line or block:

,c<space>

$address = str_replace(" ", "+", $address);

$json = file_get_contents("http://maps.google.com/maps/api/geocode/json?address=$address&sensor=false&region=$region");
$json = json_decode($json);

$lat = $json->{'results'}[0]->{'geometry'}->{'location'}->{'lat'};
$long = $json->{'results'}[0]->{'geometry'}->{'location'}->{'lng'};

I just ran into this question and, while it is old, I figured I'd add an answer for the archives. The OP asked about for loops, but their goal was to gather a random sample of rows from the table. For that task, Postgres 9.5+ offers the TABLESAMPLE clause on WHERE. Here's a good rundown:

https://www.2ndquadrant.com/en/blog/tablesample-in-postgresql-9-5-2/

I tend to use Bernoulli as it's row-based rather than page-based, but the original question is about a specific row count. For that, there's a built-in extension:

https://www.postgresql.org/docs/current/tsm-system-rows.html

CREATE EXTENSION tsm_system_rows;

Then you can grab whatever number of rows you want:

select * from playtime tablesample system_rows (15);

Instead of adding "ws." before every Range, as suggested above, you can add "ws.activate" before Call instead.

This will get you into the worksheet you want to work on.

If you just want to get your HDFS back to normal state and don't worry much about the data, then

This will list the corrupt HDFS blocks:

hdfs fsck -list-corruptfileblocks

This will delete the corrupted HDFS blocks:

hdfs fsck / -delete

Note that, you might have to use sudo -u hdfs if you are not the sudo user (assuming "hdfs" is name of the sudo user)

If both arrays are in the correct order; where each item corresponds to its associated member identifier then you can simply use.

var merge = _.merge(arr1, arr2);

Which is the short version of:

var merge = _.chain(arr1).zip(arr2).map(function(item) {
    return _.merge.apply(null, item);
}).value();

Or, if the data in the arrays is not in any particular order, you can look up the associated item by the member value.

var merge = _.map(arr1, function(item) {
    return _.merge(item, _.find(arr2, { 'member' : item.member }));
});

You can easily convert this to a mixin. See the example below:

_.mixin({_x000D_
  'mergeByKey' : function(arr1, arr2, key) {_x000D_
    var criteria = {};_x000D_
    criteria[key] = null;_x000D_
    return _.map(arr1, function(item) {_x000D_
      criteria[key] = item[key];_x000D_
      return _.merge(item, _.find(arr2, criteria));_x000D_
    });_x000D_
  }_x000D_
});_x000D_
_x000D_
var arr1 = [{_x000D_
  "member": 'ObjectId("57989cbe54cf5d2ce83ff9d6")',_x000D_
  "bank": 'ObjectId("575b052ca6f66a5732749ecc")',_x000D_
  "country": 'ObjectId("575b0523a6f66a5732749ecb")'_x000D_
}, {_x000D_
  "member": 'ObjectId("57989cbe54cf5d2ce83ff9d8")',_x000D_
  "bank": 'ObjectId("575b052ca6f66a5732749ecc")',_x000D_
  "country": 'ObjectId("575b0523a6f66a5732749ecb")'_x000D_
}];_x000D_
_x000D_
var arr2 = [{_x000D_
  "member": 'ObjectId("57989cbe54cf5d2ce83ff9d8")',_x000D_
  "name": 'yyyyyyyyyy',_x000D_
  "age": 26_x000D_
}, {_x000D_
  "member": 'ObjectId("57989cbe54cf5d2ce83ff9d6")',_x000D_
  "name": 'xxxxxx',_x000D_
  "age": 25_x000D_
}];_x000D_
_x000D_
var arr3 = _.mergeByKey(arr1, arr2, 'member');_x000D_
_x000D_
document.body.innerHTML = JSON.stringify(arr3, null, 4);

For one-dimensional sorted arrays, it would be much more simpler and efficient O(log(n)) to use numpy.searchsorted which returns a NumPy integer (position). For example,

arr = np.array([1, 1, 1, 2, 3, 3, 4])
i = np.searchsorted(arr, 3)

Just make sure the array is already sorted

Also check if returned index i actually contains the searched element, since searchsorted's main objective is to find indices where elements should be inserted to maintain order.

if arr[i] == 3:
    print("present")
else:
    print("not present")

You can use the MailDefinition class.

This is how you use it:

MailDefinition md = new MailDefinition();
md.From = "[email protected]";
md.IsBodyHtml = true;
md.Subject = "Test of MailDefinition";

ListDictionary replacements = new ListDictionary();
replacements.Add("{name}", "Martin");
replacements.Add("{country}", "Denmark");

string body = "<div>Hello {name} You're from {country}.</div>";

MailMessage msg = md.CreateMailMessage("[email protected]", replacements, body, new System.Web.UI.Control());

Also, I've written a blog post on how to generate HTML e-mail body in C# using templates using the MailDefinition class.

What suited my purpose was to create a div that was always bounded within the overall browser window by a fixed amount.

What worked, at least on firefox, was this

<div style="position: absolute; top: 127px; left: 75px;right: 75px; bottom: 50px;">

Insofar as the actual window is not forced into scrolling, the div preserves its boundaries to the window edge during all re-sizing.

Hope this saves someone some time.

Here is a concise summary of what most answers are talking about.

Let's say we have two variables and $1 is set to 'one':

set one two
a=hello
b=world

The table below explains the different contexts where we can combine the values of a and b to create a new variable, c.

Context                               | Expression            | Result (value of c)
--------------------------------------+-----------------------+---------------------
Two variables                         | c=$a$b                | helloworld
A variable and a literal              | c=${a}_world          | hello_world
A variable and a literal              | c=$1world             | oneworld
A variable and a literal              | c=$a/world            | hello/world
A variable, a literal, with a space   | c=${a}" world"        | hello world
A more complex expression             | c="${a}_one|${b}_2"   | hello_one|world_2
Using += operator (Bash 3.1 or later) | c=$a; c+=$b           | helloworld
Append literal with +=                | c=$a; c+=" world"     | hello world

A few notes:

• enclosing the RHS of an assignment in double quotes is generally a good practice, though it is quite optional in many cases
• += is better from a performance standpoint if a big string is being constructed in small increments, especially in a loop
• use {} around variable names to disambiguate their expansion (as in row 2 in the table above). As seen on rows 3 and 4, there is no need for {} unless a variable is being concatenated with a string that starts with a character that is a valid first character in shell variable name, that is alphabet or underscore.

See also:

• BashFAQ/013 - How can I concatenate two variables?
• When do we need curly braces around shell variables?

You can not specify the password from the command line but you can do either using ssh keys or using sshpass as suggested by John C. or using a expect script.

To use sshpass, you need to install it first. Then

sshpass -f <(printf '%s\n' your_password) ssh user@hostname

instead of using sshpass -p your_password. As mentioned by Charles Duffy in the comments, it is safer to supply the password from a file or from a variable instead of from command line.

BTW, a little explanation for the <(command) syntax. The shell executes the command inside the parentheses and replaces the whole thing with a file descriptor, which is connected to the command's stdout.

simple add and div atribute to each meta tag example

<meta id="mtlink" name="url" content="">
<meta id="mtdesc" name="description" content="" />
<meta id="mtkwrds" name="keywords" content="" />

now like normal div change for ex. n click

<a href="#" onClick="changeTags(); return false;">Change Meta Tags</a>

function change tags with jQuery

function changeTags(){
   $("#mtlink").attr("content","http://albup.com");
   $("#mtdesc").attr("content","music all the time");
   $("#mtkwrds").attr("content","mp3, download music, ");

}

The same way Boston came up with its street plan. They followed the cow paths already there, and built houses where the streets weren't, and after a while it was too much trouble to change.

I got this error too even I ran cmd as an Administrator.

The root cause is: The file is from VCS(subversion, perforce, etc.), and when I checked the properties of this file, its' Attributes is Read-only.

So the solution is:

• (1) disable the 'Read-only' Attribute;
• (2) check out from VCS, let the file under the status of read&write.

Perhaps a use might be:

#debug = []

def debuglog(text, obj=None):
    " Simple little logger. "
    try:
        debug   # does global exist?
    except NameError:
        pass    # if not, don't even bother displaying
    except:
        print('Unknown cause. Debug debuglog().')
    else:
        # debug does exist.
        # Now test if you want to log this debug message
        # from caller "obj"
        try:
            if obj in debug:
                print(text)     # stdout
        except TypeError:
            print('The global "debug" flag should be an iterable.')
        except:
            print('Unknown cause. Debug debuglog().')

def myfunc():
    debuglog('Made it to myfunc()', myfunc)

debug = [myfunc,]
myfunc()

Maybe this will lead you too a use.

Yes, they're in the same "local scope", and actually code like this is common in Python:

if condition:
  x = 'something'
else:
  x = 'something else'

use(x)

Note that x isn't declared or initialized before the condition, like it would be in C or Java, for example.

In other words, Python does not have block-level scopes. Be careful, though, with examples such as

if False:
    x = 3
print(x)

which would clearly raise a NameError exception.

String path = "C:"+File.separator+"hello";
String fname= path+File.separator+"abc.txt";
    File f = new File(path);
    File f1 = new File(fname);

    f.mkdirs() ;
    try {
        f1.createNewFile();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
}

This should create a new file inside a directory

Here is assembly code:

7f0b024734be:       48 8d 14 f5 00 00 00    lea    rdx,[rsi*8]
7f0b024734c5:       00
7f0b024734c6:       48 03 13                add    rdx,QWORD PTR [rbx]
7f0b024734c9:       48 8d 7a 10             lea    rdi,[rdx+16]
7f0b024734cd:       8b 5f 08                mov    ebx,DWORD PTR [rdi+8]
7f0b024734d0:       89 d8                   mov    eax,ebx
7f0b024734d2:       c1 f8 03                sar    eax,0x3
7f0b024734d5:       85 db                   test   ebx,ebx
7f0b024734d7:       0f 8e cb 05 00 00       jle    0x7f0b02473aa8

And what it does is:

rdx = 0x00007f0a808d4ed2 * 8; // equals 0x0003F854046A7690. WTF???
rdx = rdx + something from old gen heap; // results 0x000600007f090486
rdi = rdx + 16; // results 0x000600007f090496
ebx = something from edi address (0x000600007f090496) + 8

Well I've had a look at the address map and there is nothing mapped to 0x000600007f090496 which is why you are getting a SEGV. Are you getting the same error with 1.6.0_26 JVM? Can you try it on a 32bit JVM? Looks like a JVM issue to me. Why would it do the first rdx=0x0... * 8 thing?

You must use ToList() method first to take rows from database and then select items as a class. Try this:

public partial class Dog {
    public string BreedName  { get; set; }}

List<Dog> GetDogsWithBreedNames(){
    var db = new DogDataContext(ConnectString);
    var result = (from d in db.Dogs
                  join b in db.Breeds on d.BreedId equals b.BreedId
                  select new
                  {
                      Name = d.Name,
                      BreedName = b.BreedName
                  }).ToList()
                    .Select(x=> 
                          new Dog{
                              Name = x.Name,
                              BreedName = x.BreedName,
                          }).ToList();
return result;}

So, the trick is first ToList(). It is immediately makes the query and gets the data from database. Second trick is Selecting items and using object initializer to generate new objects with items loaded.

Hope this helps.

If your Object contains Objects then check if they are null, if it have primitives check for their default values.

for Instance:

Person Object 
name Property with getter and setter

to check if name is not initialized. 

Person p = new Person();
if(p.getName()!=null)

This is one way of doing it:

document.getElementById("mytext").value = "My value";

In his book, "Secrets of Javascript Ninja", John Resig (creator of jQuery) has a really simple code which will handle cross-browser console.log issues. He explains that he would like to have a log message which works with all browsers and here is how he coded it:

function log() {
  try {
    console.log.apply(console, arguments);
  } catch(e) {
  try {
    opera.postError.apply(opera, arguments);
  }
  catch(e) {
    alert(Array.prototype.join.call( arguments, " "));
  }
}

NSString *message = @"Some message...";

UIAlertView *toast = [[UIAlertView alloc] initWithTitle:nil
                                                message:message
                                               delegate:nil
                                      cancelButtonTitle:nil
                                      otherButtonTitles:nil, nil];
[toast show];
        
int duration = 1; // duration in seconds
        
dispatch_after(dispatch_time(DISPATCH_TIME_NOW, duration * NSEC_PER_SEC), dispatch_get_main_queue(), ^{
    [toast dismissWithClickedButtonIndex:0 animated:YES];
});

Using UIAlertViewController for iOS 9 or later

NSString *message = @"Some message...";

UIAlertController *alert = [UIAlertController alertControllerWithTitle:nil
                                                               message:message
                                                        preferredStyle:UIAlertControllerStyleAlert];

[self presentViewController:alert animated:YES completion:nil];

int duration = 1; // duration in seconds

dispatch_after(dispatch_time(DISPATCH_TIME_NOW, duration * NSEC_PER_SEC), dispatch_get_main_queue(), ^{
    [alert dismissViewControllerAnimated:YES completion:nil];
});

Swift 3.2

let message = "Some message..."
let alert = UIAlertController(title: nil, message: message, preferredStyle: .alert)
self.present(alert, animated: true)
    
// duration in seconds
let duration: Double = 5
    
DispatchQueue.main.asyncAfter(deadline: DispatchTime.now() + duration) {
    alert.dismiss(animated: true)
}

Before apply .setBounds(..) try to convert current Drawable into ScaleDrawable

drawable = new ScaleDrawable(drawable, 0, width, height).getDrawable();

after that

drawable.setBounds(0, 0, width, height);

will work

There have been a lot of good answers around the use of crontab, but no mention of a simpler method, such as using cron.

Using cron would take advantage of system files and directories located at /etc/crontab, /etc/cron.daily,weekly,hourly or /etc/cron.d/:

cat > /etc/cron.d/<job> << EOF
SHELL=/bin/bash 
PATH=/sbin:/bin:/usr/sbin:/usr/bin 
MAILTO=root HOME=/  
01 * * * * <user> <command>
EOF

In this above example, we created a file in /etc/cron.d/, provided the environment variables for the command to execute successfully, and provided the user for the command, and the command itself. This file should not be executable and the name should only contain alpha-numeric and hyphens (more details below).

To give a thorough answer though, let's look at the differences between crontab vs cron/crond:

crontab -- maintain tables for driving cron for individual users

For those who want to run the job in the context of their user on the system, using crontab may make perfect sense.

cron -- daemon to execute scheduled commands

For those who use configuration management or want to manage jobs for other users, in which case we should use cron.

A quick excerpt from the manpages gives you a few examples of what to and not to do:

/etc/crontab and the files in /etc/cron.d must be owned by root, and must not be group- or other-writable. In contrast to the spool area, the files under /etc/cron.d or the files under /etc/cron.hourly, /etc/cron.daily, /etc/cron.weekly and /etc/cron.monthly may also be symlinks, provided that both the symlink and the file it points to are owned by root. The files under /etc/cron.d do not need to be executable, while the files under /etc/cron.hourly, /etc/cron.daily, /etc/cron.weekly and /etc/cron.monthly do, as they are run by run-parts (see run-parts(8) for more information).

Source: http://manpages.ubuntu.com/manpages/trusty/man8/cron.8.html

Managing crons in this manner is easier and more scalable from a system perspective, but will not always be the best solution.

Remember to add MatTableModule in your app.module's imports i.e.

In Angular 9+

import { MatTableModule } from '@angular/material/table'  

@NgModule({
  imports: [
    // ...
    MatTableModule
    // ...
  ]
})

Less than Angular 9

import { MatTableModule } from '@angular/material'  

@NgModule({
  imports: [
    // ...
    MatTableModule
    // ...
  ]
})

Have you tried adding lines below to your web.xml?

<context-param>
   <param-name>com.sun.faces.enableRestoreView11Compatibility</param-name>
   <param-value>true</param-value>
</context-param>

I found this to be very effective when I encountered this issue.

In my case, I was missing something really trivial.

<input value={state.myObject.inputValue} />

My state was the following when I was getting the warning:

state = {
   myObject: undefined
}

By alternating my state to reference the input of my value, my issue was solved:

state = {
   myObject: {
      inputValue: ''
   }
}

The first parameter of Html.RadioButtonFor() should be the property name you're using, and the second parameter should be the value of that specific radio button. Then they'll have the same name attribute value and the helper will select the given radio button when/if it matches the property value.

Example:

<div class="editor-field">
    <%= Html.RadioButtonFor(m => m.Gender, "M" ) %> Male
    <%= Html.RadioButtonFor(m => m.Gender, "F" ) %> Female
</div>

Here's a more specific example:

I made a quick MVC project named "DeleteMeQuestion" (DeleteMe prefix so I know that I can remove it later after I forget about it).

I made the following model:

namespace DeleteMeQuestion.Models
{
    public class QuizModel
    {
        public int ParentQuestionId { get; set; }
        public int QuestionId { get; set; }
        public string QuestionDisplayText { get; set; }
        public List<Response> Responses { get; set; }

        [Range(1,999, ErrorMessage = "Please choose a response.")]
        public int SelectedResponse { get; set; }
    }

    public class Response
    {
        public int ResponseId { get; set; }
        public int ChildQuestionId { get; set; }
        public string ResponseDisplayText { get; set; }
    }
}

There's a simple range validator in the model, just for fun. Next up, I made the following controller:

namespace DeleteMeQuestion.Controllers
{
    [HandleError]
    public class HomeController : Controller
    {
        public ActionResult Index(int? id)
        {
            // TODO: get question to show based on method parameter 
            var model = GetModel(id);
            return View(model);
        }

        [HttpPost]
        public ActionResult Index(int? id, QuizModel model)
        {
            if (!ModelState.IsValid)

                                                        },

                                                            ResponseDisplayText = "Blue"
                                                        },
                                                    new Response
                                                        {

                                                            ResponseDisplayText = "Green"
                                                        },
                                                }
            };

            return model;
        }
    }
}

Finally, I made the following view that makes use of the model:

<%@ Page Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<DeleteMeQuestion.Models.QuizModel>" %>

<asp:Content ContentPlaceHolderID="TitleContent" runat="server">

<asp:Content ContentPlaceHolderID="MainContent" runat="server">

    <% using (Html.BeginForm()) { %>

        <div>

            <h1><%: Model.QuestionDisplayText %></h1>

            <div>
            <ul>
            <% foreach (var item in Model.Responses) { %>
                <li>
                    <%= Html.RadioButtonFor(m => m.SelectedResponse, item.ResponseId, new {id="Response" + item.ResponseId}) %>
                    <label for="Response<%: item.ResponseId %>"><%: item.ResponseDisplayText %></label>
                </li>
            <% } %>
            </ul>

            <%= Html.ValidationMessageFor(m => m.SelectedResponse) %>

        </div>

        <input type="submit" value="Submit" />

    <% } %>

</asp:Content>

As I understand your context, you have questions with a list of available answers. Each answer will dictate the next question. Hopefully that makes sense from my model and TODO comments.

This gives you the radio buttons with the same name attribute, but different ID attributes.

If you not want include other function like 'ReDimPreserve' could use temporal matrix for resizing. On based to your code:

 Dim n As Integer, m As Integer, i as Long, j as Long
 Dim arrTemporal() as Variant

    n = 1
    m = 0
    Dim arrCity() As String
    ReDim arrCity(n, m)

    n = n + 1
    m = m + 1

    'VBA automatically adapts the size of the receiving matrix.
    arrTemporal = arrCity
    ReDim arrCity(n, m)

    'Loop for assign values to arrCity
    For i = 1 To UBound(arrTemporal , 1)
        For j = 1 To UBound(arrTemporal , 2)
            arrCity(i, j) = arrTemporal (i, j)
        Next
    Next

If you not declare of type VBA assume that is Variant.

Dim n as Integer, m As Integer

You can use

TF_FORCE_GPU_ALLOW_GROWTH=true

in your environment variables.

In tensorflow code:

bool GPUBFCAllocator::GetAllowGrowthValue(const GPUOptions& gpu_options) {
  const char* force_allow_growth_string =
      std::getenv("TF_FORCE_GPU_ALLOW_GROWTH");
  if (force_allow_growth_string == nullptr) {
    return gpu_options.allow_growth();
}

One option is to use Python's slicing and indexing features to logically evaluate the places where your condition holds and overwrite the data there.

Assuming you can load your data directly into pandas with pandas.read_csv then the following code might be helpful for you.

import pandas
df = pandas.read_csv("test.csv")
df.loc[df.ID == 103, 'FirstName'] = "Matt"
df.loc[df.ID == 103, 'LastName'] = "Jones"

As mentioned in the comments, you can also do the assignment to both columns in one shot:

df.loc[df.ID == 103, ['FirstName', 'LastName']] = 'Matt', 'Jones'

Note that you'll need pandas version 0.11 or newer to make use of loc for overwrite assignment operations.

Another way to do it is to use what is called chained assignment. The behavior of this is less stable and so it is not considered the best solution (it is explicitly discouraged in the docs), but it is useful to know about:

import pandas
df = pandas.read_csv("test.csv")
df['FirstName'][df.ID == 103] = "Matt"
df['LastName'][df.ID == 103] = "Jones"

OpenSSH has been added to Windows as of autumn 2018, and is included in Windows 10 and Windows Server 2019.

So you can use it in command prompt or power shell like bellow.

C:\Users\Parsa>scp [email protected]:/etc/cassandra/cassandra.yaml F:\Temporary
[email protected]'s password:
cassandra.yaml                                  100%   66KB  71.3KB/s   00:00

(I know this question is pretty old now but this can be helpful for newcomers to this question)

break x if ((int)strcmp(y, "hello")) == 0

On some implementations gdb might not know the return type of strcmp. That means you would have to cast, otherwise it would always evaluate to true!

From my experience in React Native, you can also restart your CLI and this error goes away.

When you are reading the file, have you considered reading it line by line? This would allow you to check if your line contains the file as your are reading, and you could then perform whatever logic you needed based on that?

Scanner scanner = new Scanner("Student.txt");
String currentLine;

while((currentLine = scanner.readLine()) != null)
{
    if(currentLine.indexOf("Your String"))
    {
         //Perform logic
    }
}

You could use a variable to hold the line number, or you could also have a boolean indicating if you have passed the line that contains your string:

Scanner scanner = new Scanner("Student.txt");
String currentLine;
int lineNumber = 0;
Boolean passedLine = false;
while((currentLine = scanner.readLine()) != null)
{
    if(currentLine.indexOf("Your String"))
    {
         //Do task
         passedLine = true;
    }
    if(passedLine)
    {
       //Do other task after passing the line.
    }
    lineNumber++;
}

Object.defineProperty() is a global function..Its not available inside the function which declares the object otherwise.You'll have to use it statically...

Have your tried using the 'return' keyword?

def rps():
    return True

From http://hc.apache.org/httpclient-3.x/sslguide.html:

Protocol.registerProtocol("https", 
new Protocol("https", new MySSLSocketFactory(), 443));
HttpClient httpclient = new HttpClient();
GetMethod httpget = new GetMethod("https://www.whatever.com/");
try {
  httpclient.executeMethod(httpget);
      System.out.println(httpget.getStatusLine());
} finally {
      httpget.releaseConnection();
}

Where MySSLSocketFactory example can be found here. It references a TrustManager, which you can modify to trust everything (although you must consider this!)

use

$imageString = file_get_contents("http://example.com/image.jpg");
$save = file_put_contents('Image/saveto/image.jpg',$imageString);

You will always get warnings of blocked content in most browsers when trying to display non secure content on an https page. This is tricky if you want to embed stuff from other sites that aren't behind ssl. You can turn off the warnings or remove the blocking in your own browser but for other visitors it's a problem.

One way to do it is to load the content server side and save the images and other things to your server and display them from https.

You can also try using a service like embed.ly and get the content through them. They have support for getting the content behind https.

Script its left and top properties as the number of pixels from the left edge and top edge respectively. It must have position: absolute;

var d = document.getElementById('yourDivId');
d.style.position = "absolute";
d.style.left = x_pos+'px';
d.style.top = y_pos+'px';

Or do it as a function so you can attach it to an event like onmousedown

function placeDiv(x_pos, y_pos) {
  var d = document.getElementById('yourDivId');
  d.style.position = "absolute";
  d.style.left = x_pos+'px';
  d.style.top = y_pos+'px';
}

Give a class for eg: scroll to the textarea tag. And in the css add this property -

.scroll::-webkit-scrollbar {
   display: none;
 }

<textarea class='scroll'></textarea>

It worked for without missing the scroll part

I had this issue while 'watching' tests. When the tests were edited, the watch re-ran the tests, but they failed due to this very reason.

I fixed it by checking if the model exists then use it, else create it.

import mongoose from 'mongoose';
import user from './schemas/user';

export const User = mongoose.models.User || mongoose.model('User', user);

This can be done easily through Java8 using forEach and removeIf method.

Take two lists. Iterate from listA and compare elements inside listB

Write any condition inside removeIf method.

Hope this will help

listToCompareFrom.forEach(entity -> listToRemoveFrom.removeIf(x -> x.contains(entity)));

A question mark is a signifier for 'any type'. ? alone means

Any type extending Object (including Object)

while your example above means

Any type extending or implementing HasWord (including HasWord if HasWord is a non-abstract class)

I had the same issue and resolved by adding "Connection Time" value in web.config file. locate the connectionStrings and add Connection Timeout=3600"

here is the sample

  <connectionStrings>
    <add name="MyConn" providerName="System.Data.SqlClient" connectionString="Data Source=MySQLServer;Initial Catalog=MyDB;User ID=sa;Password=123;Connection Timeout=3600" />
  </connectionStrings>

Try this:

Open PgAdmin -> Files -> Open pgpass.conf

You would get the path of pgpass.conf at the bottom of the window. Go to that location and open this file, you can find your password there.

Reference

If the above does not work, you may consider trying this:

 1. edit pg_hba.conf to allow trust authorization temporarily
 2. Reload the config file (pg_ctl reload)
 3. Connect and issue ALTER ROLE / PASSWORD to set the new password
 4. edit pg_hba.conf again and restore the previous settings
 5. Reload the config file again

This way work for me with Eclipse in Android developer tool from Google -righ click - property - java build path - add external JAR

point to: android-support-v7-appcompat.jar in /sdk/extras/android/support/v7/appcompat/libs

Then

import android.support.v7.app.ActionBarActivity;

As others have pointed out, string is always nullable in C#. I suspect you are asking the question because you are not able to leave the middle name as null or blank? I suspect the problem is with your validation attributes, most likely the RegEx. I'm not able to fully parse RegEx in my head but I think your RegEx insists on the first character being present. I could be wrong - RegEx is hard. In any case, try commenting out your validation attributes and see if it works, then add them back in one at a time.

let mergeArray = arrA.filter(aItem => !arrB.find(bItem => aItem.name === bItem.name))

It's as simple as that:

function isMacintosh() {
  return navigator.platform.indexOf('Mac') > -1
}

function isWindows() {
  return navigator.platform.indexOf('Win') > -1
}

You can do funny things then like:

var isMac = isMacintosh();
var isPC = !isMacintosh();

Maybe a syntax error in your case, you may change the line to:

directory = str(r"C:\Users\Josh\Desktop\20130216").replace('\\','\\\\')

which give you the right following output:

C:\\Users\\Josh\\Desktop\\20130216

Don't confuse, if you won't give any strWindowFeatures then it will open in a new tab.

window.open('https://play.google.com/store/apps/details?id=com.drishya');

Collections.sort( new ArrayList( coll ) );

When CPU/math computing power is limited:

There are times (such as in my work) when computing power is scarce (e.g. no floating point processor, working with small microcontrollers) where some trig functions can take an exorbitant amount of CPU time (e.g. 3000+ clock cycles), so when I only need an approximation, especially if if the CPU must not be tied up for a long time, I use this to minimize CPU overhead:

/**------------------------------------------------------------------------
 * \brief  Great Circle distance approximation in km over short distances.
 *
 * Can be off by as much as 10%.
 *
 * approx_distance_in_mi = sqrt(x * x + y * y)
 *
 * where x = 69.1 * (lat2 - lat1)
 * and y = 69.1 * (lon2 - lon1) * cos(lat1/57.3)
 *//*----------------------------------------------------------------------*/
double    ApproximateDisatanceBetweenTwoLatLonsInKm(
                  double lat1, double lon1,
                  double lat2, double lon2
                  ) {
    double  ldRadians, ldCosR, x, y;

    ldRadians = (lat1 / 57.3) * 0.017453292519943295769236907684886;
    ldCosR = cos(ldRadians);
    x = 69.1 * (lat2 - lat1);
    y = 69.1 * (lon2 - lon1) * ldCosR;

    return sqrt(x * x + y * y) * 1.609344;  /* Converts mi to km. */
}

In addition to @dawg's great answer, the equivalent solution using walrus operator (Python >= 3.8):

with open(filename, 'rb') as f:
    while buf := f.read(max_size):
        process(buf)

One way to compare your local version before pushing it on the remote repo (kind of push in dry-run):

Use TortoiseGit:
Right click on the root folder project > TortoiseGit > Diff with previous version >
for Version 2 choose refs/remotes/origin/master

You may not have permission to dba_sequences. So you can always just do:

select * from user_sequences;

use

   statusCode: {
    404: function() {
      alert('page not found');
    }
  }

-

$.ajax({
    type: 'POST',
    url: '/controller/action',
    data: $form.serialize(),
    success: function(data){
        alert('horray! 200 status code!');
    },
    statusCode: {
    404: function() {
      alert('page not found');
    },

    400: function() {
       alert('bad request');
   }
  }

});

Alternatively, you could override your spinner adapter, and provide an empty view for position 0 in your getView method, and a view with 0dp height in the getDropDownView method.

This way, you have an initial text such as "Select an Option..." that shows up when the spinner is first loaded, but it is not an option for the user to choose (technically it is, but because the height is 0, they can't see it).

http://www.refulz.com:8082/index.php#tab2?foo=789

Property    Result
------------------------------------------
host        www.refulz.com:8082
hostname    www.refulz.com
port        8082
protocol    http:
pathname    index.php
href        http://www.refulz.com:8082/index.php#tab2
hash        #tab2
search      ?foo=789

var x = $(location).attr('<property>');

This will work only if you have jQuery. For example:

<html>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.2.6/jquery.min.js"></script>
<script>
  $(location).attr('href');      // http://www.refulz.com:8082/index.php#tab2
  $(location).attr('pathname');  // index.php
</script>
</html>

there's also an interesting tool called CUFON. There's a demonstration of how to use it in this blog It's really simple and interesting. Also, it doesn't allow people to ctrl+c/ctrl+v the generated content.

I had almost the same as Jesper, only I reused the webclient and disposed it correctly. Also I cleaned up some responses by removing the extra \n at the end.

    private static IPAddress GetExternalIp () {
      using (WebClient client = new WebClient()) {
        List<String> hosts = new List<String>();
        hosts.Add("https://icanhazip.com");
        hosts.Add("https://api.ipify.org");
        hosts.Add("https://ipinfo.io/ip");
        hosts.Add("https://wtfismyip.com/text");
        hosts.Add("https://checkip.amazonaws.com/");
        hosts.Add("https://bot.whatismyipaddress.com/");
        hosts.Add("https://ipecho.net/plain");
        foreach (String host in hosts) {
          try {
            String ipAdressString = client.DownloadString(host);
            ipAdressString = ipAdressString.Replace("\n", "");
            return IPAddress.Parse(ipAdressString);
          } catch {
          }
        }
      }
      return null;
    }

hasOwnProperty() is a nice property to validate object keys. Example:

var obj = {a:1, b:2};

obj.hasOwnProperty('a') // true

As with all technologies, it has its ups and downs. If you are using an iframe to get around a properly developed site, then of course it is bad practice. However sometimes an iframe is acceptable.

One of the main problems with an iframe has to do with bookmarks and navigation. If you are using it to simply embed a page inside your content, I think that is fine. That is what an iframe is for.

However I've seen iframes abused as well. It should never be used as an integral part of your site, but as a piece of content within a site.

Usually, if you can do it without an iframe, that is a better option. I'm sure others here may have more information or more specific examples, it all comes down to the problem you are trying to solve.

With that said, if you are limited to HTML and have no access to a backend like PHP or ASP.NET etc, sometimes an iframe is your only option.

In my case it was a table with an ENUM that accepts the days of the week as integers (0 to 6). When inserting the value 0 as an integer I got the error message "Data truncated for column ..." so to fix it I had to cast the integer to a string. So instead of:

$item->day = 0;

I had to do;

$item->day = (string) 0;

It looks silly to cast the zero like that but in my case it was in a Laravel factory, and I had to write it like this:

$factory->define(App\Schedule::class, function (Faker $faker) {
    return [
        'day' => (string) $faker->numberBetween(0, 6),
        //
    ];
});

Just remove the ( and the ) on your SELECT statement:

insert into table2 (Name, Subject, student_id, result)
select Name, Subject, student_id, result
from table1;

If git was to rename detached HEAD I would have it named as a HEAD that isn’t identified by a branch and will soon be forgotten.

We as people can easily remember branch names. We do git checkout new-button-feature / git checkout main. main and new-button-feature are easy to remember. And we can just do git branch and get a list of all branches. But to do the same with just commits you'd have to do git reflog which is very tedious. Because you have thousands of commits but only very few branches.

A detached commit’s identifier is just its SHA. So suppose you checked out a commit (not a branch) i.e. you did git checkout d747dd10e450871928a56c9cb7c6577cf61fdf31 you'll get:

Note: checking out 'd747dd10e450871928a56c9cb7c6577cf61fdf31'.

You are in 'detached HEAD' state.

...

Then if you made some changes and made a commit, you're still NOT on a branch.

Do you think you'd remember the commit SHA? You won't!

git doesn't want this to happen. Hence it's informing your HEAD is not associated to a branch so you're more inclined to checkout a new branch. As a result below that message it also says:

If you want to create a new branch to retain commits you create, you may do so (now or later) by using -b with the checkout command again. Example:

git checkout -b

To go a bit deeper a branch is built in a way that it's smart. It will update its HEAD as you make commits. Tags on the other hand are not meant to be like that. If you checkout a tag, then you're again on a detached HEAD. The main reason is that if you make a new commit from that tag then given that that commit is not referenced by anything (not any branch or tag) then still its considered a detached HEAD.

Attached HEADs can only happen when you're on a branch.

For more see here

HEAD is a pointer, and it points — directly or indirectly — to a particular commit:

Attached HEAD means that it is attached to some branch (i.e. it points to a branch).

Detached HEAD means that it is not attached to any branch, i.e. it points directly to some commit.

To look at from another angle, if you're on a branch and do cat .git/HEAD you'd get:

ref: refs/heads/Your-current-branch-name

Then if you do cat refs/heads/Your-current-branch-name then you'd also see the commit that your branch is pointing/referencing to.

However if you were on a detached HEAD you and cat .git/HEAD you'd just get the SHA of the commit and nothing more:

639ce5dd952a645b7c3fcbe89e88e3dd081a9912

By nothing more I mean the head isn't pointing to any branch. It's just directly pointing to a commit.

As a result of all this, anytime you checkout a commit, even if that commit was the latest commit of your main branch, you're still in a detached HEAD because your HEAD is not pointing to any branches. Hence even checking out a tag is will put you in a detached HEAD

One thing to note, if you have a log4j.properties file on your classpath you do not need to call BasicConfigurator. A description of how to configure the properties file is here.

You could pinpoint whether your IDE is causing the issue by trying to run this class from the command line with log4j.jar and log4j.properties on your classpath.

I had same issue I could resolved issue with replace 'localhost' with IP which is '0.0.0.0'

best bet is targeting features not devices unless you have to, bootstrap do well and you can extend on their breakpoints, for instance targeting pixel density and larger screens above 1920

I had to do the following because, if the properties were not declared in the correct order, it would randomly break words at the wrong place and without adding a hyphen.

    -moz-white-space: pre-wrap;
white-space: pre-wrap;        
    hyphens: auto;
    -ms-word-break: break-all;
    -ms-word-wrap: break-all;
    -webkit-word-break: break-word;
    -webkit-word-wrap: break-word;
word-break: break-word;
word-wrap: break-word;
    -webkit-hyphens: auto;
    -moz-hyphens: auto;
    -ms-hyphens: auto;
hyphens: auto;

Another way of viewing the full content of the cells in a pandas dataframe is to use IPython's display functions:

from IPython.display import HTML

HTML(df.to_html())

easier way. You could make your object inherit from the Error object. Example:

function NotImplementError(message)
{
    this.message = message;
    Error.call();
    Error.call(message);
} 

what we are doing is using the function call() which call the constructor of the Error class so is basicly the same thing as implementing a class inheritance in other object oriented languages.

For getting all the info about the cordova package use this command:

npm info cordova

This article helps. In particular, this section:

-File

Runs the specified script in the local scope ("dot-sourced"), so that the functions and variables that the script creates are available in the current session. Enter the script file path and any parameters. File must be the last parameter in the command, because all characters typed after the File parameter name are interpreted as the script file path followed by the script parameters.

i.e.

powershell.exe -File "C:\myfile.ps1" arg1 arg2 arg3

means run the file myfile.ps1 and arg1 arg2 & arg3 are the parameters for the PowerShell script.

I Hope this will help you.

This did the trick for me: I was able to find which macro called a particular query. Incidentally, the reason someone who does know how to code in VBA would want to write something like this is when they've inherited something macro-ish written by someone who doesn't know how to code in VBA.

You will need to use strip() because of the extra bits in the strings.

A2 = [float(x.strip('"')) for x in A1]

There's a much better way to achieve your desired result, using SQL Server's analytic (or windowing) functions.

SELECT DISTINCT Date, MAX(Score) OVER(PARTITION BY Date) FROM ScoresTable

If you need more than just the date and max score combinations, you can use ranking functions, eg:

SELECT  *
FROM    ScoresTable t
JOIN (   
    SELECT 
        ScoreId,
        ROW_NUMBER() OVER (PARTITION BY Date ORDER BY Score DESC) AS [Rank] 
        FROM ScoresTable
) window ON window.ScoreId = p.ScoreId AND window.[Rank] = 1

You may want to use RANK() instead of ROW_NUMBER() if you want multiple records to be returned if they both share the same MAX(Score).

A different approach. Use Tween.js for the counter. It allows the counter to slow down, speed up, bounce, and a slew of other goodies, as the counter gets to where its going.

PS, doesn't use jQuery - but obviously could.

This lifecycle method is invoked as soon as the updating happens. The most common use case for the componentDidUpdate() method is updating the DOM in response to prop or state changes.

You can call setState() in this lifecycle, but keep in mind that you will need to wrap it in a condition to check for state or prop changes from previous state. Incorrect usage of setState() can lead to an infinite loop. Take a look at the example below that shows a typical usage example of this lifecycle method.

componentDidUpdate(prevProps) {
 //Typical usage, don't forget to compare the props
 if (this.props.userName !== prevProps.userName) {
   this.fetchData(this.props.userName);
 }
}

Notice in the above example that we are comparing the current props to the previous props. This is to check if there has been a change in props from what it currently is. In this case, there won’t be a need to make the API call if the props did not change.

For more info, refer to the official docs:

Would this parser help you?

https://github.com/fiann/jquery.ogp

It parses meta OG data to JSON, so you can just use the data directly. If you prefer, you can read/write them directly using JQuery, of course. For example:

$("meta[property='og:title']").attr("content", document.title);
$("meta[property='og:url']").attr("content", location.toString());

Note the single-quotes around the attribute values; this prevents parse errors in jQuery.

You probably have an old version of wget. I suggest installing wget using Chocolatey, the package manager for Windows. This should give you a more recent version (if not the latest).

Run this command after having installed Chocolatey (as Administrator):

choco install wget

I don't think it's a matter of being Pythonic or elegant. It's a matter of preventing exceptions as much as you can. Exceptions are meant to handle errors that might occur in code or events you have no control over.

In this case, you have full control when checking if an item is an attribute or in a dictionary, so avoid nested exceptions and stick with your second attempt.

Use \W which is equivalent to [^a-zA-Z0-9_]. Check the documentation, https://docs.python.org/2/library/re.html

Import re
s =  'h^&ell`.,|o w]{+orld'
replaced_string = re.sub(r'\W+', '*', s)
output: 'h*ell*o*w*orld'

update: This solution will exclude underscore as well. If you want only alphabets and numbers to be excluded, then solution by nneonneo is more appropriate.

The output went to stderr. Use 2> to capture that.

$make 2> file

JACKSON Library

One option would be to use Jackson library. First import the latest version (now is):

<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-databind</artifactId>
    <version>2.7.0</version>
</dependency>

Then, you can implement the correct answer as follows:

import com.fasterxml.jackson.databind.ObjectMapper;

public final class JSONUtils {
  private JSONUtils(){}

  public static boolean isJSONValid(String jsonInString ) {
    try {
       final ObjectMapper mapper = new ObjectMapper();
       mapper.readTree(jsonInString);
       return true;
    } catch (IOException e) {
       return false;
    }
  }
}

Google GSON option

Another option is to use Google Gson. Import the dependency:

<dependency>
    <groupId>com.google.code.gson</groupId>
    <artifactId>gson</artifactId>
    <version>2.5</version>
</dependency>

Again, you can implement the proposed solution as:

import com.google.gson.Gson;

public final class JSONUtils {
  private static final Gson gson = new Gson();

  private JSONUtils(){}

  public static boolean isJSONValid(String jsonInString) {
      try {
          gson.fromJson(jsonInString, Object.class);
          return true;
      } catch(com.google.gson.JsonSyntaxException ex) { 
          return false;
      }
  }
}

A simple test follows here:

//A valid JSON String to parse.
String validJsonString = "{ \"developers\": [{ \"firstName\":\"Linus\" , \"lastName\":\"Torvalds\" }, " +
        "{ \"firstName\":\"John\" , \"lastName\":\"von Neumann\" } ]}";

// Invalid String with a missing parenthesis at the beginning.
String invalidJsonString = "\"developers\": [ \"firstName\":\"Linus\" , \"lastName\":\"Torvalds\" }, " +
        "{ \"firstName\":\"John\" , \"lastName\":\"von Neumann\" } ]}";

boolean firstStringValid = JSONUtils.isJSONValid(validJsonString); //true
boolean secondStringValid = JSONUtils.isJSONValid(invalidJsonString); //false

Please, observe that there could be a "minor" issue due to trailing commas that will be fixed in release 3.0.0.

I had this error and fixed it by adding the guard on readyState and status shown here:

var xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function() {
    if (this.readyState == 4 && this.status == 200) {
          // Your code here
   }
};

In the case you have no natural partition value and just want an ordered number regardless of the partition you can just do a row_number over a constant, in the following example i've just used 'X'. Hope this helps someone

select 
    ROW_NUMBER() OVER(PARTITION BY num ORDER BY col1) as aliascol1, 
    period_next_id, period_name_long
from 
(
  select distinct col1, period_name_long, 'X' as num
  from {TABLE} 
) as x

You can have multiple tags when building the image:

$ docker build -t whenry/fedora-jboss:latest -t whenry/fedora-jboss:v2.1 .

Reference: https://docs.docker.com/engine/reference/commandline/build/#tag-image-t

Surya, your way won't work, because of two reasons:

1. you can't close driver during evaluation of test as it will loose focus, before switching to active element, and you'll get NoSuchWindowException.
2. if test are run on ChromeDriver you`ll get not a window, but tab on click in your application. As SeleniumDriver can't act with tabs, only switchs between windows, it hangs on click where new tab is being opening, and crashes on timeout.

Use which(mydata_2$height_chad1 == 2585)

Short example

df <- data.frame(x = c(1,1,2,3,4,5,6,3),
                 y = c(5,4,6,7,8,3,2,4))
df
  x y
1 1 5
2 1 4
3 2 6
4 3 7
5 4 8
6 5 3
7 6 2
8 3 4

which(df$x == 3)
[1] 4 8

length(which(df$x == 3))
[1] 2

count(df, vars = "x")
  x freq
1 1    2
2 2    1
3 3    2
4 4    1
5 5    1
6 6    1

df[which(df$x == 3),]
  x y
4 3 7
8 3 4

As Matt Weller pointed out, you can use the length function. The count function in plyr can be used to return the count of each unique column value.

For me WORKSPACE was a valid property of the pipeline itself. So when I handed over this to a Groovy method as parameter context from the pipeline script itself, I was able to access the correct value using "... ${context.WORKSPACE} ..."

(on Jenkins 2.222.3, Build Pipeline Plugin 1.5.8, Pipeline: Nodes and Processes 2.35)

Got this error as well lately. Tried all the above fixes, but none worked.

To disable it, type services.msc in command prompt, then right click and disable Internet Connection Sharing. I edited the properties of it as well to disable at startup. Mine looks like so now: services capture screenshot.

The target you tried to add in InputProps is not the same target you wanted which is in React.FormEvent

So, the solution I could come up with was, extending the event related types to add your target type, as:

interface MyEventTarget extends EventTarget {
    value: string
}

interface MyFormEvent<T> extends React.FormEvent<T> {
    target: MyEventTarget
}

interface InputProps extends React.HTMLProps<Input> {
    onChange?: React.EventHandler<MyFormEvent<Input>>;
}

Once you have those classes, you can use your input component as

<Input onChange={e => alert(e.target.value)} />

without compile errors. In fact, you can also use the first two interfaces above for your other components.

A key currently still is not required ("required" in the meaning "it will not work without"), but I think there is a good reason for the warning.

But in the documentation you may read now : "All JavaScript API applications require authentication."

I'm sure that it's planned for the future , that Javascript API Applications will not work without a key(as it has been in V2).

You better use a key when you want to be sure that your application will still work in 1 or 2 years.

EditPad Pro and PowerGREP have a unique feature that allows you to change the case of the backreference. \U1 inserts the first backreference in uppercase, \L1 in lowercase and \F1 with the first character in uppercase and the remainder in lowercase. Finally, \I1 inserts it with the first letter of each word capitalized, and the other letters in lowercase.

Try Run This Query

 ALTER TABLE tablename AUTO_INCREMENT = value;

Or Try This Query For The Reset Auto Increment

 ALTER TABLE `tablename` CHANGE `id` `id` INT(10) UNSIGNED NOT NULL;

And Set Auto Increment Then Run This Query

  ALTER TABLE `tablename` CHANGE `id` `id` INT(10) UNSIGNED NOT NULL AUTO_INCREMENT;

Git doesn't store empty folders. Just make sure there's a file in the folder like doc/foo.txt and run git add doc or git add doc/foo.txt, and the folder will be added to your local repository once you've committed (and appear on GitHub once you've pushed it).

How about something like this.

function objectToArray( $object ){
   if( !is_object( $object ) && !is_array( $object ) ){
    return $object;
 }
if( is_object( $object ) ){
    $object = get_object_vars( $object );
}
    return array_map( 'objectToArray', $object );
}

and call this function with your object

$array = objectToArray( $yourObject );

reference

<select name="name">
   <option <?php if ($_GET['name'] == 'a') { ?>selected="true" <?php }; ?>value="a">a</option>
   <option <?php if ($_GET['name'] == 'b') { ?>selected="true" <?php }; ?>value="b">b</option>
</select>

Or simply:

Date.now

From MDN documentation:

The Date.now() method returns the number of milliseconds elapsed since January 1, 1970

Available since ECMAScript 5.1

It's the same as was mentioned above (new Date().getTime()), but more shortcutted version.

You would use an MvcHtmlString if you want to pass raw HTML to an MVC helper method and you don't want the helper method to encode the HTML.

You can use this constructor

console.log( moment().format('YYYY-MM-DD HH:mm:ss') )_x000D_
_x000D_
console.log( moment({h:0, m:0, s:0, ms:0}).format('YYYY-MM-DD HH:mm:ss') )

I'm developing an application that needs currency conversion, and been using Open Exchange Rates because I wouldn't be paying since the app is in testing. But as of September 2012 Open Exchange Rates is gonna be paid for non-personal, so I checked out that they were using the Yahoo Finance Webservice (the one that "doesn't exist") and looking for documentation on it got here, and opted to use YQL.

Using YQL with the Yahoo Finance table (yahoo.finance.quotes) linked by NT3RP, currencies appear with symbol="ISOCODE=X", for example: "ARS=X" for Argentine Peso, "AUD=X" for Australian Dollar. "USD=X" doesn't exist, but it would be 1, since the rest are rates against USD.

The "price" value on the OP API is in the field "LastTradePriceOnly" of the table. For my application I used the "Ask" field.

In additional to the popular K8s, jasypt or vault solutions, there's also Karmahostage. It enables you to do:

@EncryptedValue("${application.secret}")
private String application;

It works the same way jasypt does, but encryption happens on a dedicated saas solution, with a more fine-grained ACL model attached to it.

Why would you make it VARCHAR? It doesn't vary. It's always 64 characters, which can be determined by running anything into one of the online SHA-256 calculators.

Solved my problem by adding this to my ListView:

android:scrollbars="none"

DataSet is collection of DataTables.... you can get the datatable from DataSet as below.

//here ds is dataset
DatTable dt = ds.Table[0]; /// table of dataset

In SQL Server 2008 you can use a multi-table update as follows:

UPDATE tblindiantime 
SET tblindiantime.CountryName = contacts.BusinessCountry
FROM tblindiantime 
JOIN contacts
ON -- join condition here

You need a join condition to specify which row should be updated.

If the target table is currently empty then you should use an INSERT instead:

INSERT INTO tblindiantime (CountryName)
SELECT BusinessCountry FROM contacts

UPDATE T1,T2 
INNER JOIN T1 ON  T1.Brands = T2.Brands
SET 
T1.Inci = T2.Inci
WHERE
    T1.Category= T2.Category
AND
    T1.Date = T2.Date

Naturally, my approach was to loop through the first array once and check the index of each value in the second array. If the index is > -1, then push it onto the returned array.

?Array.prototype.diff = function(arr2) {
    var ret = [];
    for(var i in this) {   
        if(arr2.indexOf(this[i]) > -1){
            ret.push(this[i]);
        }
    }
    return ret;
};

? My solution doesn't use two loops like others do so it may run a bit faster. If you want to avoid using for..in, you can sort both arrays first to reindex all their values:

Array.prototype.diff = function(arr2) {
    var ret = [];
    this.sort();
    arr2.sort();
    for(var i = 0; i < this.length; i += 1) {
        if(arr2.indexOf(this[i]) > -1){
            ret.push(this[i]);
        }
    }
    return ret;
};

Usage would look like:

var array1 = ["cat", "sum","fun", "run", "hut"];
var array2 = ["bat", "cat","dog","sun", "hut", "gut"];

console.log(array1.diff(array2));

If you have an issue/problem with extending the Array prototype, you could easily change this to a function.

var diff = function(arr, arr2) {

And you'd change anywhere where the func originally said this to arr2.

Check out the example from enable-cors.org:

In your ExpressJS app on node.js, do the following with your routes:

app.all('/', function(req, res, next) {
  res.header("Access-Control-Allow-Origin", "*");
  res.header("Access-Control-Allow-Headers", "X-Requested-With");
  next();
 });

app.get('/', function(req, res, next) {
  // Handle the get for this route
});

app.post('/', function(req, res, next) {
 // Handle the post for this route
});

The first call (app.all) should be made before all the other routes in your app (or at least the ones you want to be CORS enabled).

[Edit]

If you want the headers to show up for static files as well, try this (make sure it's before the call to use(express.static()):

app.use(function(req, res, next) {
  res.header("Access-Control-Allow-Origin", "*");
  res.header("Access-Control-Allow-Headers", "X-Requested-With");
  next();
});

I tested this with your code, and got the headers on assets from the public directory:

var express = require('express')
  , app = express.createServer();

app.configure(function () {
    app.use(express.methodOverride());
    app.use(express.bodyParser());
    app.use(function(req, res, next) {
      res.header("Access-Control-Allow-Origin", "*");
      res.header("Access-Control-Allow-Headers", "X-Requested-With");
      next();
    });
    app.use(app.router);
});

app.configure('development', function () {
    app.use(express.static(__dirname + '/public'));
    app.use(express.errorHandler({ dumpExceptions: true, showStack: true }));
});

app.configure('production', function () {
    app.use(express.static(__dirname + '/public'));
    app.use(express.errorHandler());
});

app.listen(8888);
console.log('express running at http://localhost:%d', 8888);

You could, of course, package the function up into a module so you can do something like

// cors.js

module.exports = function() {
  return function(req, res, next) {
    res.header("Access-Control-Allow-Origin", "*");
    res.header("Access-Control-Allow-Headers", "X-Requested-With");
    next();
  };
}

// server.js

cors = require('./cors');
app.use(cors());

node-dev

node-dev is great alternative to both nodemon and supervisor for developers who like to get growl (or libnotify) notifications on their desktop whenever the server restarts or when there is an error or change occur in file.

Installation:

npm install -g node-dev

Use node-dev, instead of node:

node-dev app.js

This is an old question but alot of the answers in here use VB or VBA. The tag says vbscript (which is how I got here).

The answers here got kind of muddled since VB is super broad where you can have so many applications of it. My answer is solely on vbscript and accomplishes my case of formatting in YYYYMMDD in vbscript

Sharing what I've learned:

1. There are all the DateTime functions in vbscript defined here so you can mix-n-match to get the result that you want
2. What I needed was to get the current date and format it in YYYYMMDD to do that I just needed to concat DatePart like so for the current Date: date = DatePart("yyyy",Date) & DatePart("m",Date) & DatePart("d",Date)

That's all, I hope this helps someone.

On Eclipse make a raw delete of Tomcat configuration folder under project "Servers". I tried it as last hope and it worked.

I am Using Design Support Library. And just by using custom theme I achived transparent Status Bar when Opened Navigation Drawer.

<style name="NavigationStyle" parent="Theme.AppCompat.Light.NoActionBar">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/primaryColor</item>
    <item name="colorPrimaryDark">@color/primaryColorDark</item>

    <!-- To Make Navigation Drawer Fill Status Bar and become Transparent Too -->
    <item name="android:windowDrawsSystemBarBackgrounds">true</item>
    <item name="android:statusBarColor">@android:color/transparent</item>

</style>

Finally add theme in Manifest File

<activity
  ........
  ........
 android:theme="@style/NavigationStyle"> 
</activity>

Do not forget to use the property, android:fitsSystemWindows="true" in "DrawerLayout"

It is common for comparison functions to return 0 on "equals", so that they can also return a negative number for "less than" and a positive number for "greater than". strcmp() and memcmp() work like this.

It is, however, idiomatic for zero to be false and nonzero to be true, because this is how the C flow control and logical boolean operators work. So it might be that the return values chosen for this function are fine, but it is the function's name that is in error (it should really just be called compare() or similar).

look at Comparing Inline and Multi-Statement Table-Valued Functions you can find good descriptions and performance benchmarks

I have used a syntax like this before:

$(ProjectDir)..\headers

or

..\headers

Context is an "interface" to the global information about an application environment. In practice, Context is actually an abstract class, whose implementation is provided by the Android system.

It allows access to application-specific resources and classes, as well as up-calls for application-level operations, such as launching activities, broadcasting and receiving intents, etc.

In the following picture, you can see a hierarchy of classes, where Context is the root class of this hierarchy. In particular, it's worth emphasizing that Activity is a descendant of Context.

To get the value you would do this:

document.getElementById("genderf").value;

But to check, whether the radio button is checked or selected:

document.getElementById("genderf").checked;

Very simple:

Just use the below formation###

rules_id = ["9","10"]

sql2 = "SELECT * FROM attendance_rules_staff WHERE id in"+str(tuple(rules_id))

note the str(tuple(rules_id)).

How can I go from this

A - B - C - D - E 
                |
                master

to this?

A - B - C - D - E 
    |           |
    master      newbranch

With two commands

• git branch -m master newbranch

giving

A - B - C - D - E 
                |
                newbranch

and

• git branch master B

giving

A - B - C - D - E
    |           |
    master      newbranch

You have to add following in header:

<script type="text/javascript">
        function fixform() {
            if (opener.document.getElementById("aspnetForm").target != "_blank") return;

            opener.document.getElementById("aspnetForm").target = "";
            opener.document.getElementById("aspnetForm").action = opener.location.href;
            }
</script>

Then call fixform() in load your page.

Just just using Transformers It did not work for me I was getting type cast exception.

sqlQuery.setResultTransformer(Transformers.aliasToBean(MYEngityName.class)) did notwork because I was getting Array of Object in the return list element not the fixed MYEngityName type of list element.

It worked for me when I make following changes When I have added sqlQuery.addScalar(-) each selected column and its type and for specific String type column we dont have to map its type. like addScalar("langCode");

And I have join MYEngityName with NextEnity we cant just select * in the Query it will give array of Object in the return list.

Below code sample :

session = ht.getSessionFactory().openSession();
                String sql = new StringBuffer("Select txnId,nft.mId,count,retryReason,langCode FROM  MYEngityName nft INNER JOIN NextEntity m on nft.mId  =  m.id where nft.txnId < ").append(lastTxnId)
                       .append(StringUtils.isNotBlank(regionalCountryOfService)? " And  m.countryOfService in ( "+ regionalCountryOfService +" )" :"")
                       .append(" order by nft.txnId desc").toString();
                SQLQuery sqlQuery = session.createSQLQuery(sql);
                sqlQuery.setResultTransformer(Transformers.aliasToBean(MYEngityName.class));
                sqlQuery.addScalar("txnId",Hibernate.LONG)
                        .addScalar("merchantId",Hibernate.INTEGER)
                        .addScalar("count",Hibernate.BYTE)
                        .addScalar("retryReason")
                        .addScalar("langCode");
                sqlQuery.setMaxResults(maxLimit);
                return sqlQuery.list();

It might help some one. in this way work for me.

Make your size a factor in your dataframe by:

temp$size_f = factor(temp$size, levels=c('50%','100%','150%','200%'))

Then change the facet_grid(.~size) to facet_grid(.~size_f)

Then plot:

The graphs are now in the correct order.

From MSDN:

Use of two sequential underscore characters ( __ ) at the beginning of an identifier, or a single leading underscore followed by a capital letter, is reserved for C++ implementations in all scopes. You should avoid using one leading underscore followed by a lowercase letter for names with file scope because of possible conflicts with current or future reserved identifiers.

This means that you can use a single underscore as a member variable prefix, as long as it's followed by a lower-case letter.

This is apparently taken from section 17.4.3.1.2 of the C++ standard, but I can't find an original source for the full standard online.

See also this question.

Compare date only instead of date + time (NOW) with:

CURDATE()

You can try this way also.

<?php
     $obj = json_decode("{}"); 
     var_dump($obj);
?>

Output:

object(stdClass)#1 (0) { }

Same problem in VS 2013

I added in Web.config :

<add assembly="System.Data.Entity, Version=4.0.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089" />

It worked like a charm.

I found it on page: http://www.programmer.bz/Home/tabid/115/asp_net_sql/281/The-type-or-namespace-name-Objects-does-not-exist-in-the-namespace-SystemData.aspx

window.setInterval(function() {
 alert('test');
}, 10000);

window.setInterval

Calls a function repeatedly, with a fixed time delay between each call to that function.

modelBuilder.Property(x => x.FirstName).IsUnicode().IsRequired().HasMaxLength(50);

Upsert is what you want. UPSERT syntax was added to SQLite with version 3.24.0 (2018-06-04).

CREATE TABLE phonebook2(
  name TEXT PRIMARY KEY,
  phonenumber TEXT,
  validDate DATE
);

INSERT INTO phonebook2(name,phonenumber,validDate)
  VALUES('Alice','704-555-1212','2018-05-08')
  ON CONFLICT(name) DO UPDATE SET
    phonenumber=excluded.phonenumber,
    validDate=excluded.validDate
  WHERE excluded.validDate>phonebook2.validDate;

Be warned that at this point the actual word "UPSERT" is not part of the upsert syntax.

The correct syntax is

INSERT INTO ... ON CONFLICT(...) DO UPDATE SET...

and if you are doing INSERT INTO SELECT ... your select needs at least WHERE true to solve parser ambiguity about the token ON with the join syntax.

Be warned that INSERT OR REPLACE... will delete the record before inserting a new one if it has to replace, which could be bad if you have foreign key cascades or other delete triggers.

No need to generate a function for it. Just do it like this:

$('a').each(function(){
    var s = $(this).clone().wrap('<p>').parent().html();
    console.log(s);
});

(Your browser's console will show what is logged, by the way. Most of the latest browsers since around 2009 have this feature.)

The magic is this on the end:

.clone().wrap('<p>').parent().html();

The clone means you're not actually disturbing the DOM. Run it without it and you'll see p tags inserted before/after all hyperlinks (in this example), which is undesirable. So, yes, use .clone().

The way it works is that it takes each a tag, makes a clone of it in RAM, wraps with p tags, gets the parent of it (meaning the p tag), and then gets the innerHTML property of it.

EDIT: Took advice and changed div tags to p tags because it's less typing and works the same.

It is true that if you present a view controller modally on the iPhone, it will always be presented full screen no matter how you present it on the top view controller of a navigation controller or any other way around. But you can always show the navigation bar with the following workaround way:

Rather than presenting that view controller modally present a navigation controller modally with its root view controller set as the view controller you want:

MyViewController *myViewController = [[MyViewController alloc] initWithNibName:nil bundle:nil];
UINavigationController *navigationController = 
    [[UINavigationController alloc] initWithRootViewController:myViewController];

//now present this navigation controller modally 
[self presentViewController:navigationController
                   animated:YES
                   completion:^{

                        }];

You should see a navigation bar when your view is presented modally.

public static string XmlSerializeToString(this object objectInstance)
{
    var serializer = new XmlSerializer(objectInstance.GetType());
    var sb = new StringBuilder();

    using (TextWriter writer = new StringWriter(sb))
    {
        serializer.Serialize(writer, objectInstance);
    }

    return sb.ToString();
}

public static T XmlDeserializeFromString<T>(this string objectData)
{
    return (T)XmlDeserializeFromString(objectData, typeof(T));
}

public static object XmlDeserializeFromString(this string objectData, Type type)
{
    var serializer = new XmlSerializer(type);
    object result;

    using (TextReader reader = new StringReader(objectData))
    {
        result = serializer.Deserialize(reader);
    }

    return result;
}

To use it:

//Make XML
var settings = new ObjectCustomerSettings();
var xmlString = settings.XmlSerializeToString();

//Make Object
var settings = xmlString.XmlDeserializeFromString<ObjectCustomerSettings>(); 

Although this is valid in HTML, you can't use an ID starting with an integer in CSS selectors.

As pointed out, you can use getElementById instead, but you can also still achieve the same with a querySelector:

document.querySelector("[id='22']")

It's valid, but rather nasty. I would suggest it's generally bad to allow fall-throughs as it can lead to some very messy spaghetti code.

It's almost certainly better to break these cases up into several switch statements or smaller functions.

[edit] @Tristopia: Your example:

Example from UCS-2 to UTF-8 conversion 

r is the destination array, 
wc is the input wchar_t  

switch(utf8_length) 
{ 
    /* Note: code falls through cases! */ 
    case 3: r[2] = 0x80 | (wc & 0x3f); wc >>= 6; wc |= 0x800; 
    case 2: r[1] = 0x80 | (wc & 0x3f); wc >>= 6; wc |= 0x0c0; 
    case 1: r[0] = wc;
}

would be clearer as to it's intention (I think) if it were written like this:

if( utf8_length >= 1 )
{
    r[0] = wc;

    if( utf8_length >= 2 )
    {
        r[1] = 0x80 | (wc & 0x3f); wc >>= 6; wc |= 0x0c0; 

        if( utf8_length == 3 )
        {
            r[2] = 0x80 | (wc & 0x3f); wc >>= 6; wc |= 0x800; 
        }
    }
}   

[edit2] @Tristopia: Your second example is probably the cleanest example of a good use for follow-through:

for(i=0; s[i]; i++)
{
    switch(s[i])
    {
    case '"': 
    case '\'': 
    case '\\': 
        d[dlen++] = '\\'; 
        /* fall through */ 
    default: 
        d[dlen++] = s[i]; 
    } 
}

..but personally I would split the comment recognition into it's own function:

bool isComment(char charInQuestion)
{   
    bool charIsComment = false;
    switch(charInQuestion)
    {
    case '"': 
    case '\'': 
    case '\\': 
        charIsComment = true; 
    default: 
        charIsComment = false; 
    } 
    return charIsComment;
}

for(i=0; s[i]; i++)
{
    if( isComment(s[i]) )
    {
        d[dlen++] = '\\'; 
    }
    d[dlen++] = s[i]; 
}

Add it after Placeholder attribute.

I used your own pivot as a nested query and came to this result:

SELECT
  [sub].[chardate],
  SUM(ISNULL([Australia], 0)) AS [Transactions Australia],
  SUM(CASE WHEN [Australia] IS NOT NULL THEN [TotalAmount] ELSE 0 END) AS [Amount Australia],
  SUM(ISNULL([Austria], 0)) AS [Transactions Austria],
  SUM(CASE WHEN [Austria] IS NOT NULL THEN [TotalAmount] ELSE 0 END) AS [Amount Austria]
FROM
(
  select * 
  from  mytransactions
  pivot (sum (totalcount) for country in ([Australia], [Austria])) as pvt
) AS [sub]
GROUP BY
  [sub].[chardate],
  [sub].[numericmonth]
ORDER BY 
  [sub].[numericmonth] ASC

Here is the Fiddle.

None of these answers worked for me, at least not for scrolling down a facebook search result page, but I found after a lot of testing this solution:

while driver.find_element_by_tag_name('div'):
    driver.execute_script("window.scrollTo(0, document.body.scrollHeight);")
    Divs=driver.find_element_by_tag_name('div').text
    if 'End of Results' in Divs:
        print 'end'
        break
    else:
        continue

1. Delete early created devices.
2. Close Android studio.
3. Open: Control panel -> System & security -> System -> Advanced system settings -> Environment variables.
4. Create New variable "ANDROID_SDK_HOME" and set new path(in my case it was F:\Coding2019\Android\AVDdevices). Push 'ok'.
5. Open Android Studio.
6. Create new device. After creating in drop-down menu click "View Details" to see new path of new AVD.
