I can't upvote/comment yet, but +1 for manually removing the lock file haha.

My C9 workspace crashed on me and triggered an unexpected shutdown. The API advises: https://docs.mongodb.com/manual/tutorial/recover-data-following-unexpected-shutdown/

.. but removing data/mongo.lock worked for me :).

Also, just in case you're getting a connection refusal (which happened to me), running the repair command before removing the lock file could solve your problem (it did mine).

sudo -u mongodb mongod --repair --dbpath /var/lib/mongodb/

Sample solution Press Window+R and type services.msc to view all the services on machine Then find MongoDBServer right click it and start it. Then go to C:\Program Files\MongoDB\Server\4.2\bin and type mongo on command promt.

For Windows 7

You may specify an alternate path for \data\db with the dbpath setting for mongod.exe,

as in the following example:

c:\mongodb\bin\mongod.exe --dbpath c:\mongodb\data\db

or

you can set dbpath through Configuration File.

Working with BOOTSTRAP 3 : Short and Simple

Yes. Have a look at Wikipedia and Cloanto Implementation of INI File Format (see bottom of page).

Try this:

if (getResult.Equals(new KeyValuePair<T,U>()))

or this:

if (getResult.Equals(default(KeyValuePair<T,U>)))

This means that a TCP RST was received and the connection is now closed. This occurs when a packet is sent from your end of the connection but the other end does not recognize the connection; it will send back a packet with the RST bit set in order to forcibly close the connection.

This can happen if the other side crashes and then comes back up or if it calls close() on the socket while there is data from you in transit, and is an indication to you that some of the data that you previously sent may not have been received.

It is up to you whether that is an error; if the information you were sending was only for the benefit of the remote client then it may not matter that any final data may have been lost. However you should close the socket and free up any other resources associated with the connection.

You can use the back button callback, like this:

- (BOOL) navigationShouldPopOnBackButton
{
    [self backAction];
    return NO;
}

- (void) backAction {
    // your code goes here
    // show confirmation alert, for example
    // ...
}

for swift version you can do something like in global scope

extension UIViewController {
     @objc func navigationShouldPopOnBackButton() -> Bool {
     return true
    }
}

extension UINavigationController: UINavigationBarDelegate {
     public func navigationBar(_ navigationBar: UINavigationBar, shouldPop item: UINavigationItem) -> Bool {
          return self.topViewController?.navigationShouldPopOnBackButton() ?? true
    }
}

Below one you put in the viewcontroller where you want to control back button action:

override func navigationShouldPopOnBackButton() -> Bool {
    self.backAction()//Your action you want to perform.

    return true
}

You are trying to access the struct statically with a . instead of ::, nor are its members static. Either instantiate ReducedForm:

ReducedForm rf;
rf.iSimplifiedNumerator = 5;

or change the members to static like this:

struct ReducedForm
{
    static int iSimplifiedNumerator;
    static int iSimplifiedDenominator;
};

In the latter case, you must access the members with :: instead of . I highly doubt however that the latter is what you are going for ;)

For Mac Users: The debug.keystore file exists in ~/.android directory. Sometimes, due to the relative path, the above mentioned error keeps on popping up.

As others have mentioned: CSS-3 says that you can use the rgba(...) syntax to specify a border color with an opacity (alpha) value.

here's a quick example if you'd like to check it.

• It works in Safari and Chrome (probably works in all webkit browsers).

• It works in Firefox

• I doubt that it works at all in IE, but I suspect that there is some filter or behavior that will make it work.

There's also this stackoverflow post, which suggests some other issues--namely, that the border renders on-top-of any background color (or background image) that you've specified; thus limiting the usefulness of border alpha in many cases.

sudo usermod -a -G docker jenkins
sudo service jenkins restart

If you're page has an Open Graph image, commonly used for social sharing, you can use it to set the background image at runtime with vanilla JavaScript like so:

<script>
  const meta = document.querySelector('[property="og:image"]');
  const body = document.querySelector("body");
  body.style.background = `url(${meta.content})`;
</script>

The above uses document.querySelector and Attribute Selectors to assign meta the first Open Graph image it selects. A similar task is performed to get the body. Finally, string interpolation is used to assign body the background.style the value of the path to the Open Graph image.

If you want the image to cover the entire viewport and stay fixed set background-size like so:

body.style.background = `url(${meta.content}) center center no-repeat fixed`;
body.style.backgroundSize = 'cover';

Using this approach you can set a low-quality background image placeholder using CSS and swap with a high-fidelity image later using an image onload event, thereby reducing perceived latency.

This would do the work and avoid the issue that you can no longer select part of the text by mouse.

$("input[type=text]").click(function() {
    if(!$(this).hasClass("selected")) {
        $(this).select();
        $(this).addClass("selected");
    }
});
$("input[type=text]").blur(function() {
    if($(this).hasClass("selected")) {
        $(this).removeClass("selected");
    }
});

For what it's worth, here are two pointless ways of doing it:

scala> case class Foo(bar: Int)
defined class Foo

scala> import scalaz._, Scalaz._
import scalaz._
import Scalaz._

scala> val c = Vector(Foo(9), Foo(11))
c: scala.collection.immutable.Vector[Foo] = Vector(Foo(9), Foo(11))

scala> c.map(((_: Foo).bar) &&& identity).toMap
res30: scala.collection.immutable.Map[Int,Foo] = Map(9 -> Foo(9), 11 -> Foo(11))

scala> c.map(((_: Foo).bar) >>= (Pair.apply[Int, Foo] _).curried).toMap
res31: scala.collection.immutable.Map[Int,Foo] = Map(9 -> Foo(9), 11 -> Foo(11))

These days, socket.on('connect', ...) is not working for me. I use the below code to check at 1st connecting.

if (socket.connected)
  console.log('socket.io is connected.')

and use this code when reconnected.

socket.on('reconnect', ()=>{
  //Your Code Here
});

This is an old post but maybe this could help people to complete the CORS problem. To complete the basic authorization problem you should avoid authorization for OPTIONS requests in your server. This is an Apache configuration example. Just add something like this in your VirtualHost or Location.

<LimitExcept OPTIONS>
    AuthType Basic
    AuthName <AUTH_NAME>
    Require valid-user
    AuthUserFile <FILE_PATH>
</LimitExcept>

Looks like npm-check-updates is the only way to make this happen now.

npm i -g npm-check-updates
ncu -u
npm install

On npm <3.11:

Simply change every dependency's version to *, then run npm update --save. (Note: broken in recent (3.11) versions of npm).

Before:

  "dependencies": {
    "express": "*",
    "mongodb": "*",
    "underscore": "*",
    "rjs": "*",
    "jade": "*",
    "async": "*"
  }

After:

  "dependencies": {
    "express": "~3.2.0",
    "mongodb": "~1.2.14",
    "underscore": "~1.4.4",
    "rjs": "~2.10.0",
    "jade": "~0.29.0",
    "async": "~0.2.7"
  }

Of course, this is the blunt hammer of updating dependencies. It's fine if—as you said—the project is empty and nothing can break.

On the other hand, if you're working in a more mature project, you probably want to verify that there are no breaking changes in your dependencies before upgrading.

To see which modules are outdated, just run npm outdated. It will list any installed dependencies that have newer versions available.

If you are using Nodemon my guess is the PORT 3000 is set in the nodemonConfig. Check if that is the case.

If removing postmaster.pid does not resolve the issue, this worked for me:

cd /usr/local/var/
rm -rf postgres/
mkdir postgres
initdb --locale=C -E UTF-8 postgres/
brew services restart postgresql

This generally means that the remote side closed the connection (usually by sending a TCP/IP RST packet). If you're working with a third-party application, the likely causes are:

• You are sending malformed data to the application (which could include sending an HTTPS request to an HTTP server)
• The network link between the client and server is going down for some reason
• You have triggered a bug in the third-party application that caused it to crash
• The third-party application has exhausted system resources

It's likely that the first case is what's happening.

You can fire up Wireshark to see exactly what is happening on the wire to narrow down the problem.

Without more specific information, it's unlikely that anyone here can really help you much.

Open the file /etc/mongod.conf and add the ip of the machine from where you are connecting, to bind_ip

bind_ip = 127.0.0.1,your Remote Machine Ip Address Here

Ex:-

bind_ip = 127.0.0.1,192.168.1.5

Restart mongodb service:

sudo service mongod restart

Make sure mongodb port is opened in the firewall.

You can also comment the line, if you are not worried about security.

I had this problem, and the cause was rather silly. I was trying out Microsoft's demo regarding running a ServiceHost from w/in a Command Line executable. I followed the instructions, including where it says to add the appropriate Service (and interface). But I got the above error.

Turns out when I added the service class, VS automatically added the configuration to the app.config. And the demo was trying to add that info too. Since it was already in the config, I removed the demo part, and it worked.

Rails scaffolds use 422 Unprocessable Entity for these kinds of errors. See RFC 4918 for more information.

Currently as of Django 2.2, the recommended way when starting a new project is to create a custom user model that inherits from AbstractUser, then point AUTH_USER_MODEL to the model.

You can do this:

/* Clearfix for the menu */
.ui-menu:after {
    content: ".";
    display: block;
    clear: both;
    visibility: hidden;
    line-height: 0;
    height: 0;
}

and also set:

.ui-menu .ui-menu-item {
    display: inline-block;
    float: left;
    margin: 0;
    padding: 0;
    width: auto;
}

In IDE's such as PTVS, PyCharm, Wing assert isinstance() statements can be used to enable code completion for some unclear objects.

Adding a FileUpload control from the code behind should work just fine, where the HasFile property should be available (for instance in your Click event).

If the properties don't appear to be available (either as a compiler error or via intellisense), you probably are referencing a different variable than you think you are.

There are two possible result rearrangements (following example by @eumiro). Einops package provides a powerful notation to describe such operations non-ambigously

>> a = np.arange(18).reshape(9,2)

# this version corresponds to eumiro's answer
>> einops.rearrange(a, '(x y) z -> z y x', x=3)

array([[[ 0,  6, 12],
        [ 2,  8, 14],
        [ 4, 10, 16]],

       [[ 1,  7, 13],
        [ 3,  9, 15],
        [ 5, 11, 17]]])

# this has the same shape, but order of elements is different (note that each paer was trasnposed)
>> einops.rearrange(a, '(x y) z -> z x y', x=3)

array([[[ 0,  2,  4],
        [ 6,  8, 10],
        [12, 14, 16]],

       [[ 1,  3,  5],
        [ 7,  9, 11],
        [13, 15, 17]]])

Convert the value to a string, add a zero in front of it (so that it's two or tree characters), and get the last to characters:

Tables work differently; sometimes counter-intuitively.

The solution is to use width on the table cells instead of max-width.

Although it may sound like in that case the cells won't shrink below the given width, they will actually.
with no restrictions on c, if you give the table a width of 70px, the widths of a, b and c will come out as 16, 42 and 12 pixels, respectively.
With a table width of 400 pixels, they behave like you say you expect in your grid above.
Only when you try to give the table too small a size (smaller than a.min+b.min+the content of C) will it fail: then the table itself will be wider than specified.

I made a snippet based on your fiddle, in which I removed all the borders and paddings and border-spacing, so you can measure the widths more accurately.

table {_x000D_
  width: 70px;_x000D_
}_x000D_
_x000D_
table, tbody, tr, td {_x000D_
  margin: 0;_x000D_
  padding: 0;_x000D_
  border: 0;_x000D_
  border-spacing: 0;_x000D_
}_x000D_
_x000D_
.a, .c {_x000D_
  background-color: red;_x000D_
}_x000D_
_x000D_
.b {_x000D_
  background-color: #F77;_x000D_
}_x000D_
_x000D_
.a {_x000D_
  min-width: 10px;_x000D_
  width: 20px;_x000D_
  max-width: 20px;_x000D_
}_x000D_
_x000D_
.b {_x000D_
  min-width: 40px;_x000D_
  width: 45px;_x000D_
  max-width: 45px;_x000D_
}_x000D_
_x000D_
.c {}

<table>_x000D_
  <tr>_x000D_
    <td class="a">A</td>_x000D_
    <td class="b">B</td>_x000D_
    <td class="c">C</td>_x000D_
  </tr>_x000D_

Easiest solution:

class OuterClass:
    outer_var = 1
    class InnerClass:
        def __init__(self):
            self.inner_var = OuterClass.outer_var

It requires you to be explicit, but doesn't take much effort.

A few of the solutions here reference the time taken for various "is even" operations, specifically n % 2 vs n & 1, without systematically checking how this varies with the size of n, which turns out to be predictive of speed.

The short answer is that if you're using reasonably sized numbers, normally < 1e9, it doesn't make much difference. If you're using larger numbers then you probably want to be using the bitwise operator.

Here's a plot to demonstrate what's going on (with Python 3.7.3, under Linux 5.1.2):

Basically as you hit "arbitrary precision" longs things get progressively slower for modulus, while remaining constant for the bitwise op. Also, note the 10**-7 multiplier on this, i.e. I can do ~30 million (small integer) checks per second.

Here's the same plot for Python 2.7.16:

which shows the optimisation that's gone into newer versions of Python.

I've only got these versions of Python on my machine, but could rerun for other versions of there's interest. There are 51 ns between 1 and 1e100 (evenly spaced on a log scale), for each point I do the equivalent of:

timeit('n % 2', f'n={n}', number=niter) 

where niter is calculated to make timeit take ~0.1 seconds, and this is repeated 5 times. The slightly awkward handling of n is to make sure we're not also benchmarking global variable lookup, which is slower than local variables. The mean of these values are used to draw the line, and the individual values are drawn as points.

WHERE clause is used for comparing values in the base table, whereas the HAVING clause can be used for filtering the results of aggregate functions in the result set of the query Click here!

You can get desired result with help of Regular Expressions.

SELECT fiberbox from fiberbox where fiberbox REGEXP '[1740|1938|1940]';

We can test the above query please click SQL fiddle

The Code Runner extension has a setting "Clear previous output", which is what I need 95% of the time.

File > Preferences > Settings > (search for "output") > Code-runner: Clear previous output

The remaining few times I will disable the setting and use the "Clear output" button (top right of the output pane) to selectively clear accumulated output.

This is in Visual Studio Code 1.33.1 with Code Runner 0.9.8.

(Setting the keybinding for Ctrl+k did not work for me, presumably because some extension has defined "chords" beginning with Ctrl-k. But "Clear previous output" was actually a better option for me.)

GNU parallel

I was making a synthetic compilation benchmark and couldn't be bothered to write a Makefile, so I used:

sudo apt-get install parallel
ls | grep -E '\.c$' | parallel -t --will-cite "gcc -c -o '{.}.o' '{}'"

Explanation:

• {.} takes the input argument and removes its extension
• -t prints out the commands being run to give us an idea of progress
• --will-cite removes the request to cite the software if you publish results using it...

parallel is so convenient that I could even do a timestamp check myself:

ls | grep -E '\.c$' | parallel -t --will-cite "\
  if ! [ -f '{.}.o' ] || [ '{}' -nt '{.}.o' ]; then
    gcc -c -o '{.}.o' '{}'
  fi
"

xargs -P can also run jobs in parallel, but it is a bit less convenient to do the extension manipulation or run multiple commands with it: Calling multiple commands through xargs

Parallel linking was asked at: Can gcc use multiple cores when linking?

TODO: I think I read somewhere that compilation can be reduced to matrix multiplication, so maybe it is also possible to speed up single file compilation for large files. But I can't find a reference now.

As Oli pointed out, you can use fmod(). Don't forget to include math.h.

SELECT t1.name
FROM table1 t1
LEFT JOIN table2 t2 ON t2.name = t1.name
WHERE t2.name IS NULL

Q: What is happening here?

A: Conceptually, we select all rows from table1 and for each row we attempt to find a row in table2 with the same value for the name column. If there is no such row, we just leave the table2 portion of our result empty for that row. Then we constrain our selection by picking only those rows in the result where the matching row does not exist. Finally, We ignore all fields from our result except for the name column (the one we are sure that exists, from table1).

While it may not be the most performant method possible in all cases, it should work in basically every database engine ever that attempts to implement ANSI 92 SQL

Have in mind that clone() doesn't work out of the box. You will have to implement Cloneable and override the clone() method making in public.

There are a few alternatives, which are preferable (since the clone() method has lots of design issues, as stated in other answers), and the copy-constructor would require manual work:

• BeanUtils.cloneBean(original) creates a shallow clone, like the one created by Object.clone(). (this class is from commons-beanutils)

• SerializationUtils.clone(original) creates a deep clone. (i.e. the whole properties graph is cloned, not only the first level) (from commons-lang), but all classes must implement Serializable

• Java Deep Cloning Library offers deep cloning without the need to implement Serializable

simple example

<?php
echo '#start main# ';
function a(){
    echo '{start[';
    for($i=1; $i<=9; $i++)
        yield $i;
    echo ']end} ';
}
foreach(a() as $v)
    echo $v.',';
echo '#end main#';
?>

output

#start main# {start[1,2,3,4,5,6,7,8,9,]end} #end main#

advanced example

<?php
echo '#start main# ';
function a(){
    echo '{start[';
    for($i=1; $i<=9; $i++)
        yield $i;
    echo ']end} ';
}
foreach(a() as $k => $v){
    if($k === 5)
        break;
    echo $k.'=>'.$v.',';
}
echo '#end main#';
?>

output

#start main# {start[0=>1,1=>2,2=>3,3=>4,4=>5,#end main#

If you look at the scope of the variable 'hoursWorked' you will see that it is a member of the class (declared as private int)

The two variables you are having trouble with are passed as parameters to the constructor.

The error message is because 'hours' is out of scope in the setter.

tofile is a convenient function to do this:

import numpy as np
a = np.asarray([ [1,2,3], [4,5,6], [7,8,9] ])
a.tofile('foo.csv',sep=',',format='%10.5f')

The man page has some useful notes:

This is a convenience function for quick storage of array data. Information on endianness and precision is lost, so this method is not a good choice for files intended to archive data or transport data between machines with different endianness. Some of these problems can be overcome by outputting the data as text files, at the expense of speed and file size.

Note. This function does not produce multi-line csv files, it saves everything to one line.

string s = "søme string";
s = Regex.Replace(s, @"[^\u0000-\u007F]+", string.Empty);

You can use groupBy of angular.filter module.
so you can do something like this:

JS:

$scope.players = [
  {name: 'Gene', team: 'alpha'},
  {name: 'George', team: 'beta'},
  {name: 'Steve', team: 'gamma'},
  {name: 'Paula', team: 'beta'},
  {name: 'Scruath', team: 'gamma'}
];

HTML:

<ul ng-repeat="(key, value) in players | groupBy: 'team'">
  Group name: {{ key }}
  <li ng-repeat="player in value">
    player: {{ player.name }} 
  </li>
</ul>

RESULT:
Group name: alpha
* player: Gene
Group name: beta
* player: George
* player: Paula
Group name: gamma
* player: Steve
* player: Scruath

UPDATE: jsbin Remember the basic requirements to use angular.filter, specifically note you must add it to your module's dependencies:

(1) You can install angular-filter using 4 different methods:

1. clone & build this repository
2. via Bower: by running $ bower install angular-filter from your terminal
3. via npm: by running $ npm install angular-filter from your terminal
4. via cdnjs http://www.cdnjs.com/libraries/angular-filter

(2) Include angular-filter.js (or angular-filter.min.js) in your index.html, after including Angular itself.

(3) Add 'angular.filter' to your main module's list of dependencies.

There is a easy way to do it.

    NSArray *myArray = @[@"5",@"4",@"3",@"2",@"1"];
    NSMutableArray *myNewArray = [[NSMutableArray alloc] init]; //this object is going to be your new array with inverse order.
    for(int i=0; i<[myNewArray count]; i++){
        [myNewArray insertObject:[myNewArray objectAtIndex:i] atIndex:0];
    }
    //other way to do it
    for(NSString *eachValue in myArray){
        [myNewArray insertObject:eachValue atIndex:0];
    }

    //in both cases your new array will look like this
    NSLog(@"myNewArray: %@", myNewArray);
    //[@"1",@"2",@"3",@"4",@"5"]

I hope this helps.

NSData *imageData = UIImagePNGRepresentation(myImage.image);

class Program
{
    static void Main(string[] args)
    {

        int transactionDate = 20201010;
        int? transactionTime = 210000;

        var agreementDate = DateTime.Today;
        var previousDate = agreementDate.AddDays(-1);

        var agreementHour = 22;
        var agreementMinute = 0;
        var agreementSecond = 0;

        var startDate = new DateTime(previousDate.Year, previousDate.Month, previousDate.Day, agreementHour, agreementMinute, agreementSecond);
        var endDate = new DateTime(agreementDate.Year, agreementDate.Month, agreementDate.Day, agreementHour, agreementMinute, agreementSecond);

        DateTime selectedDate = Convert.ToDateTime(transactionDate.ToString().Substring(6, 2) + "/" + transactionDate.ToString().Substring(4, 2) + "/" + transactionDate.ToString().Substring(0, 4) + " " + string.Format("{0:00:00:00}", transactionTime));

        Console.WriteLine("Selected Date : " + selectedDate.ToString());
        Console.WriteLine("Start Date : " + startDate.ToString());
        Console.WriteLine("End Date : " + endDate.ToString());

        if (selectedDate > startDate && selectedDate <= endDate)
            Console.WriteLine("Between two dates..");
        else if (selectedDate <= startDate)
            Console.WriteLine("Less than or equal to the start date!");
        else if (selectedDate > endDate)
            Console.WriteLine("Greater than end date!");
        else
            Console.WriteLine("Out of date ranges!");
    }
}

Simply we can format the date like,

var month = date.getMonth() + 1;
var day = date.getDate();
var date1 = (('' + day).length < 2 ? '0' : '') + day + '/' + (('' + month).length < 2 ? '0' : '') + month + '/' + date.getFullYear();
$("#txtDate").val($.datepicker.formatDate('dd/mm/yy', new Date(date1)));

Where "date" is a date in any format.

In my case, using JSX a parent component was calling other components without the "<>"

 <ComponentA someProp={someCheck ? ComponentX : ComponentY} />

fix

<ComponentA someProp={someCheck ? <ComponentX /> : <ComponentY />} />

When the iFrame points to your site like this:

<html>
  <head>
    <script type="text/javascript" src="/jquery.js"></script>
  </head>
  <body>
    <iframe id="my_frame" src="/wherev"></iframe>
  </body>
</html>

You can access iFrame DOM through this kind of thing.

var iframeBody = $(window.my_frame.document.getElementsByTagName("body")[0]);
iframeBody.append($("<h1/>").html("Hello world!"));

You are getting NullReferenceExeption because of you are using the cmb.SelectedValue which is null. the comboBox doesn't know what is the value of your custom class ComboboxItem, so either do:

ComboboxItem selectedCar = (ComboboxItem)comboBox2.SelectedItem;
int selecteVal = Convert.ToInt32(selectedCar.Value);

Or better of is use data binding like:

ComboboxItem item1 = new ComboboxItem();
item1.Text = "test";
item1.Value = "123";

ComboboxItem item2 = new ComboboxItem();
item2.Text = "test2";
item2.Value = "456";

List<ComboboxItem> items = new List<ComboboxItem> { item1, item2 };

this.comboBox1.DisplayMember = "Text";
this.comboBox1.ValueMember = "Value";
this.comboBox1.DataSource = items;

Say the table is user(id, user_name, user_email).

You can use this query:

INSERT INTO user (SELECT NULL,user_name, user_email FROM user WHERE id = 1)

In 2017, CSS media query from second answer still doesn't work on Firefox. I found a soluton for that: -moz-touch-enabled

So, here is cross-browser media query:

@media (-moz-touch-enabled: 1), (pointer:coarse) {
    .something {
        its: working;
    }
}

As of iOS 6 and onward. The new diagram is as follows:

I had a problem where I had to many columns to visually inspect on the screen so a short list comp that filters and returns the offending columns is

nan_cols = [i for i in df.columns if df[i].isnull().any()]

if that's helpful to anyone

To install Python package from github, you need to clone that repository.

git clone https://github.com/jkbr/httpie.git

Then just run the setup.py file from that directory,

sudo python setup.py install

I just found another reason why to get this error. I cleaned my GAC from all versions of a specific library and built my project with reference to specific version deployed together with the executable. When I run the project I got this exception searching for a newer version of the library.

The reason was publisher policy. When I uninstalled library's versions from GAC I forgot to uninstall publisher policy assemblies as well so instead of using my locally deployed assembly the assembly loader found publisher policy in GAC which told it to search for a newer version.

Note you can add the Microsoft.AspNetCore.WebUtilities nuget package from Microsoft and then use this to append values to query string:

QueryHelpers.AddQueryString(longurl, "action", "login1")
QueryHelpers.AddQueryString(longurl, new Dictionary<string, string> { { "action", "login1" }, { "attempts", "11" } });

Got mine working with

react-native run-ios --device="My’s iPhone"

And notice that your iphone name, the apostrophe s ' might be different. Mine is using this ’

When I need to do this, I make the other values data-values and then use js to assign them to a hidden input

<select id=select>
<option value=1 data-othervalue=2 data-someothervalue=3>
//...
</select>

<input type=hidden name=otherValue id=otherValue />
<input type=hidden name=someOtherValue id=someOtherValue />

<script>
$('#select').change(function () {
var otherValue=$(this).find('option:selected').attr('data-othervalue');
var someOtherValue=$(this).find('option:selected').attr('data-someothervalue');
$('#otherValue').val(otherValue);
$('#someOtherValue').val(someOtherValue);
});
</script>

You don't need to apply to_date() to sysdate. It is already there:

select 1
from dual 
WHERE sysdate BETWEEN TO_DATE('28/02/2014', 'DD/MM/YYYY') AND TO_DATE('20/06/2014', 'DD/MM/YYYY');

If you are concerned about the time component on the date, then use trunc():

select 1
from dual 
WHERE trunc(sysdate) BETWEEN TO_DATE('28/02/2014', 'DD/MM/YYYY') AND
                             TO_DATE('20/06/2014', 'DD/MM/YYYY');

On Mac OS use

find -E packages  -regex ".*\.(jpg|gif|png|jpeg)"

The usual pattern is EXISTS(subselect):

BEGIN
  IF EXISTS(SELECT name
              FROM test_table t
             WHERE t.id = x
               AND t.name = 'test')
  THEN
     ---
  ELSE
     ---
  END IF;

This pattern is used in PL/SQL, PL/pgSQL, SQL/PSM, ...

Daniel's script appears to be a good all encompassing solution, but even he admitted that his laptop ran out of memory. Here is an option I came up with. I based my procedure off of Mohammad Nizamuddin's post on TechNet. I added an initial cursor loop that pulls all the database names into a temporary table and then uses that to pull all the base table names from each of those databases.

You can optionally pass the fill factor you would prefer and specify a target database if you do not want to re-index all databases.

--===============================================================
-- Name:  sp_RebuildAllIndexes
-- Arguements:  [Fill Factor], [Target Database name]
-- Purpose:  Loop through all the databases on a server and
--           compile a list of all the table within them.
--           This list is then used to rebuild indexes for
--           all the tables in all the database.  Optionally,
--           you may pass a specific database name if you only
--           want to reindex that target database.
--================================================================
CREATE PROCEDURE sp_RebuildAllIndexes(
    @FillFactor     INT = 90,
    @TargetDatabase NVARCHAR(100) = NULL)

        DECLARE @TableSelect VARCHAR(MAX);
        DECLARE @DatabasesToIndex CURSOR;

        IF ISNULL( @TargetDatabase, '' ) = ''
          SET @DatabasesToIndex = CURSOR

place the required dlls in folder and set the folder path in PATH environment variable. make sure updated environment PATH variable is reflected.

If you are using Eclipse you can move files to and from the SD Card through the Android Perspective (it is called DDMS in Eclipse). Just select the Emulator in the left part of the screen and then choose the File Explorer tab. Above the list with your files should be two symbols, one with an arrow pointing at a phone, clicking this will allow you to choose a file to move to phone memory.

Basically, it's a shortcut of:

class Genre{
    private string genre;
    public string getGenre() {
        return this.genre;
    }
    public void setGenre(string theGenre) {
        this.genre = theGenre;
    }
}
//In Main method
genre g1 = new Genre();
g1.setGenre("Female");
g1.getGenre(); //Female

I have the same error and it fixed it including in the file the following

#include <stdint.h>

at the beginning of your file.

It looks like a container with the name qgis-desktop-2-4 already exists in the system. You can check the output of the below command to confirm if it indeed exists:

$ docker ps -a

The last column in the above command's output is for names.

If the container exists, remove it using:

$ docker rm qgis-desktop-2-4

Or forcefully using,

$ docker rm -f qgis-desktop-2-4

And then try creating a new container.

If you need to query large (or small) log files on Windows, the best tool I have found is Microsoft's free Log Parser 2.2. You can call it from PowerShell if you want and it will do all the heavy lifting for you, and very fast too.

adb reboot should not reboot your linux box.

But in any case, you can redirect the command to a specific adb device using adb -s <device_id> command , where

Device ID can be obtained from the command adb devices
command in this case is reboot

This should work as well

<a href="#" onclick="callFunction();">Submit</a>

<script type="text/javascript">

function callFunction()

  <?php require("functions.php");  ?>
}

If you are using intellij go to Run > Edit Configurations menu setting. A dialog box will appear. Now you can add arguments to the Program arguments input field.

It does not make any sense to call new Set(...anArrayOrSet) when adding multiple elements (from either an array or another set) to an existing set.

I use this in a reduce function, and it is just plain silly. Even if you have the ...array spread operator available, you should not use it in this case, as it wastes processor, memory, and time resources.

// Add any Map or Set to another
function addAll(target, source) {
  if (target instanceof Map) {
    Array.from(source.entries()).forEach(it => target.set(it[0], it[1]))
  } else if (target instanceof Set) {
    source.forEach(it => target.add(it))
  }
}

If you're writing for Android you can do this...

android.text.HtmlCompat.fromHtml(instruction, HtmlCompat.FROM_HTML_MODE_LEGACY).toString()

Here is function I use to fetch the url that have redirect:

const http = require('http');
const url = require('url');

function get({path, host}, callback) {
    http.get({
        path,
        host
    }, function(response) {
        if (response.headers.location) {    
            var loc = response.headers.location;
            if (loc.match(/^http/)) {
                loc = new Url(loc);
                host = loc.host;
                path = loc.path;
            } else {
                path = loc;
            }
            get({host, path}, callback);
        } else {
            callback(response);
        }
    });
}

it work the same as http.get but follow redirect.

I needed to remove special characters from an XML file. Here's how I did it. char.ToString() is the hero in this code.

string item = "<item type="line" />"
char DC4 = (char)0x14;
string fixed = item.Replace(DC4.ToString(), string.Empty);

If you use the Chocolatey package manager, you can install cURL by running this command from the command line or from PowerShell:

I got the same error. I have been using select2-3.5.2

This was my code which had error

    $('#carstatus-select').select2().val([1,2])

Below code fixed the issue.

    $('#carstatus-select').val([1,2]);

This is in response to a number of comments as my reputation isn't high enough to comment directly.

You can specify the profile at runtime as long as the application context has not yet been loaded.

// Previous answers incorrectly used "spring.active.profiles" instead of
// "spring.profiles.active" (as noted in the comments).
// Use AbstractEnvironment.ACTIVE_PROFILES_PROPERTY_NAME to avoid this mistake.

System.setProperty(AbstractEnvironment.ACTIVE_PROFILES_PROPERTY_NAME, environment);
ApplicationContext applicationContext = new ClassPathXmlApplicationContext("/META-INF/spring/applicationContext.xml");

The easiest way to get second last row from a SQL table is to use ORDER BYColumnNameDESC and set LIMIT 1,1.

Try this:

SELECT * from `TableName` ORDER BY `ColumnName` DESC LIMIT 1,1

If you would like to 'add' additional items to a page, you may want to create an array of maps. This is how I created an array of maps and then added results to it:

import { Product } from '../models/product';

products: Array<Product>;          // Initialize the array.

[...]

let i = 0;
this.service.products( i , (result) => {

    if ( i == 0 ) {
        // Create the first element of the array.
        this.products = Array(result);
    } else { 
        // Add to the array of maps.
        this.products.push(result);
    }

});

Where product.ts look like...

export class Product {
    id: number;
    [...]
}

Immutable, suitable for ReactJS:

Assume:

cosnt arr = [{id: 1, name: "Person 1"}, {id:2, name:"Person 2"}];

The updated item is the second and name is changed to Special Person:

const updatedItem = {id:2, name:"Special Person"};

Hint: the lodash has useful tools but now we have some of them on Ecmascript6+, so I just use map function that is existed on both of lodash and ecmascript6+:

const newArr = arr.map(item => item.id === 2 ? updatedItem : item);

@Override
public CharSequence filter(CharSequence source, int start, int end, Spanned dest, int dstart, int dend) {
    try {
        String prefix = dest.toString().substring(0, dstart);
        String insert = source.toString();
        String suffix = dest.toString().substring(dend);
        String input_string = prefix + insert + suffix;
        int input = Integer.parseInt(input_string);

        if (isInRange(min, max, input) || input_string.length() < String.valueOf(min).length())
            return null;
    } catch (NumberFormatException nfe) { }
    return "";
}

private boolean isInRange(int a, int b, int c) {
    return b > a ? c >= a && c <= b : c >= b && c <= a;
}

I was looking for the same thing and end up with the solution and here it's a simple example if anybody wants to go through this.

var FA = function(data){
   console.log("IN A:"+data)
   FC(data,"LastName");
};
var FC = function(data,d2){
   console.log("IN C:"+data,d2)
};
var FB = function(data){
   console.log("IN B:"+data);
    FA(data)
};
FB('FirstName')

As of Java 7, the NIO Api provides a better and more generic way of accessing the contents of Zip or Jar files. Actually, it is now a unified API which allows you to treat Zip files exactly like normal files.

In order to extract all of the files contained inside of a zip file in this API, you'd do this:

In Java 8:

private void extractAll(URI fromZip, Path toDirectory) throws IOException{
    FileSystems.newFileSystem(fromZip, Collections.emptyMap())
            .getRootDirectories()
            .forEach(root -> {
                // in a full implementation, you'd have to
                // handle directories 
                Files.walk(root).forEach(path -> Files.copy(path, toDirectory));
            });
}

In java 7:

private void extractAll(URI fromZip, Path toDirectory) throws IOException{
    FileSystem zipFs = FileSystems.newFileSystem(fromZip, Collections.emptyMap());

    for(Path root : zipFs.getRootDirectories()) {
        Files.walkFileTree(root, new SimpleFileVisitor<Path>() {
            @Override
            public FileVisitResult visitFile(Path file, BasicFileAttributes attrs) 
                    throws IOException {
                // You can do anything you want with the path here
                Files.copy(file, toDirectory);
                return FileVisitResult.CONTINUE;
            }

            @Override
            public FileVisitResult preVisitDirectory(Path dir, BasicFileAttributes attrs) 
                    throws IOException {
                // In a full implementation, you'd need to create each 
                // sub-directory of the destination directory before 
                // copying files into it
                return super.preVisitDirectory(dir, attrs);
            }
        });
    }
}

For Android API level 13 and you need to use this:

Display display = getWindowManager().getDefaultDisplay();
Point size = new Point();
display.getSize(size);
int maxX = size.x; 
int maxY = size.y;

Then (0,0) is top left corner and (maxX,maxY) is bottom right corner of the screen.

The 'getWidth()' for screen size is deprecated since API 13

Furthermore getwidth() and getHeight() are methods of android.view.View class in android.So when your java class extends View class there is no windowManager overheads.

          int maxX=getwidht();
          int maxY=getHeight();

as simple as that.

I managed to do this with the following code:

ALTER TABLE `table_name`
CHANGE COLUMN `colum_name` `colum_name` INT(11) NOT NULL AUTO_INCREMENT FIRST;

This is the only way I could make a column auto increment.

INT(11) shows that the maximum int length is 11, you can skip it if you want.

Have you tried using the concat() function?

ON tableTwo.query = concat('category_id=',tableOne.category_id)

            {
                builder.AddConfiguration(hostingContext.Configuration.GetSection("Logging"));
                builder.AddConsole();
                builder.AddDebug();
            })
            .UseIISIntegration()
            .UseDefaultServiceProvider((context, options) =>
            {
                options.ValidateScopes = context.HostingEnvironment.IsDevelopment();
            })
            .UseStartup<Startup>()
            .Build();
    }

Ant then reads it in ConfigureServices like this:

public IServiceProvider ConfigureServices(IServiceCollection services)
{
    var isDevelopment = Program.HostingEnvironment.IsDevelopment();
}

Please <staticContent /> line and erased it from the web.config.

If you check the length seperately, you can do the following:

var regularExpression  = /^[a-zA-Z]$/;

if (regularExpression.test(newPassword)) {
    alert("password should contain atleast one number and one special character");
    return false;
} 

Whenever possible, you should avoid parsing the output of ls (see Greg's wiki on the subject). Basically, the output of ls will be ambiguous if there are funny characters in any of the filenames. It's also usually a waste of time. In this case, when you execute ls -d */, what happens is that the shell expands */ to a list of subdirectories (which is already exactly what you want), passes that list as arguments to ls -d, which looks at each one, says "yep, that's a directory all right" and prints it (in an inconsistent and sometimes ambiguous format). The ls command isn't doing anything useful!

Well, ok, it is doing one thing that's useful: if there are no subdirectories, */ will get left as is, ls will look for a subdirectory named "*", not find it, print an error message that it doesn't exist (to stderr), and not print the "*/" (to stdout).

The cleaner way to make an array of subdirectory names is to use the glob (*/) without passing it to ls. But in order to avoid putting "*/" in the array if there are no actual subdirectories, you should set nullglob first (again, see Greg's wiki):

shopt -s nullglob
array=(*/)
shopt -u nullglob # Turn off nullglob to make sure it doesn't interfere with anything later
echo "${array[@]}"  # Note double-quotes to avoid extra parsing of funny characters in filenames

If you want to print an error message if there are no subdirectories, you're better off doing it yourself:

if (( ${#array[@]} == 0 )); then
    echo "No subdirectories found" >&2
fi

You can use that gist, pretty easy to use, stores your settings in local storage: https://gist.github.com/4533361

In case someone need an equivalent for macOS like I did, here is it:

lsof -i tcp:8080

After you get the PID of the process, you can kill it with:

kill -9 <PID>

Check out the @property decorator.

You can use matcher.start() and matcher.end() methods to get the group positions. So using this positions you can easily replace any text.

Add a contextmenu to your form and then assign it in the control's properties under ContextMenuStrip. Hope this helps :).

Hope this helps:

ContextMenu cm = new ContextMenu();
cm.MenuItems.Add("Item 1");
cm.MenuItems.Add("Item 2");

pictureBox1.ContextMenu = cm;

This is quite an old question but there's a much simple way of achieving this.

myButton.userInteractionEnabled = false

This will only disable any touch gestures without changing the appearance of the button

I can see that other responders have given you a complete solution. Problem with regexes is that they can be difficult to maintain/understand.

An easier solution would be to retain your existing regex, then create two new regexes to test for your "at least one alphabetic" and "at least one numeric".

So, test for this :-

/^([a-zA-Z0-9]+)$/

Then this :-

/\d/

Then this :-

/[A-Z]/i

If your string passes all three regexes, you have the answer you need.

This has not been tested but I think this should work using mod_rewrite

RewriteEngine On
RewriteCond %{HTTPS} on
RewriteRule (.*) http://%{HTTP_HOST}%{REQUEST_URI}

Another easy option was to use [HeidiSQL client][1] for PostgreSQL database.

How to go into the database tab where all the databases and tables are listed.

Click on any of the table/View which you wanted to see the DDL/create a statement of the particular table.

Now there this client do the following jobs for you for that table, on the right-hand side windows:

The first window would be for data of table

Second for your SQL Host information

Third for database-level information like which tables and what is the size

Forth which we are more concern about table/view information tab will have the create table statement readily available for you.

I can not show you in the snapshot as working with confidential data, Try it with yourself and let me know if any issues you guys found.

Use malloc() when you don't know the amount of memory needed during compile time. In case if you have read-only strings then you can use const char* str = "something"; . Note that the string is most probably be stored in a read-only memory location and you'll not be able to modify it. On the other hand if you know the string during compiler time then you can do something like: char str[10]; strcpy(str, "Something"); Here the memory is allocated from stack and you will be able to modify the str. Third case is allocating using malloc. Lets say you don'r know the length of the string during compile time. Then you can do char* str = malloc(requiredMem); strcpy(str, "Something"); free(str);

Use ?? operator at the end of your <#if> statement.

This example demonstrates how to handle null values for two lists in a Freemaker template.

List of cars:
<#if cars??>
    <#list cars as car>${car.owner};</#list>
</#if>
List of motocycles:
<#if motocycles??>
    <#list motocycles as motocycle>${motocycle.owner};</#list>
</#if>

Answer

Convert the UTC datetime to America/Denver

// create a $dt object with the UTC timezone
$dt = new DateTime('2016-12-12 12:12:12', new DateTimeZone('UTC'));

// change the timezone of the object without changing it's time
$dt->setTimezone(new DateTimeZone('America/Denver'));

// format the datetime
$dt->format('Y-m-d H:i:s T');

Notes

time() returns the unix timestamp, which is a number, it has no timezone.

date('Y-m-d H:i:s T') returns the date in the current locale timezone.

gmdate('Y-m-d H:i:s T') returns the date in UTC

date_default_timezone_set() changes the current locale timezone

to change a time in a timezone

// create a $dt object with the America/Denver timezone
$dt = new DateTime('2016-12-12 12:12:12', new DateTimeZone('America/Denver'));

// change the timezone of the object without changing it's time
$dt->setTimezone(new DateTimeZone('UTC'));

// format the datetime
$dt->format('Y-m-d H:i:s T');

here you can see all the available timezones

https://en.wikipedia.org/wiki/List_of_tz_database_time_zones

here are all the formatting options

In essence, while your SQL looks perfectly reasonable, Jet has never supported the SQL standard syntax for UPDATE. Instead, it uses its own proprietary syntax (different again from SQL Server's proprietary UPDATE syntax) which is very limited. Often, the only workarounds "Operation must use an updatable query" are very painful. Seriously consider switching to a more capable SQL product.

For some more details about your specific problems and some possible workarounds, see Update Query Based on Totals Query Fails.

I've had the same problem, but in my case Apache was already running and for some reason the XAMPP config tool didn't show that. It happened after I started XAMPP for the first time after the installation. After crashing the other Apache instances all was fine and ports 80 and 443 were free again.

So before making changes to your systeem, make sure something as obvious as the above isn't happening.

In my case -- using React with Gatsby -- the issue was solved with double-checking all of my paths. I was using React/Gatsby with Sass and the Gatsby source files were looking for the fonts in a different place than the compiled files. Once I duplicated the files into each path this problem was gone.

All .idea files that are explicitly ignored are still showing up to commit

you have to remove them from the staging area

git rm --cached .idea

now you have to commit those changes and they will be ignored from this point on.
Once git start to track changes it will not "stop" tracking them even if they were added to the .gitignore file later on.

You must explicitly remove them and then commit your removal manually in order to fully ignore them.

I found a very good jquery plugin that can ease your life with this type of operation. You can checkout https://github.com/ocombe/jQuery-keepAlive.

$.fn.keepAlive({url: 'your-route/filename', timer: 'time'},       function(response) {
        console.log(response);
      });//

I was facing the same problem in one of my projects and have decided to make a custom widget that has both the date and the time picker in one user-friendly dialog. You can get the source code along with an example at http://code.google.com/p/datetimepicker/. The code is licensed under Apache 2.0.

You can password protect SQLite3 DB. For the first time before doing any operations, set password as follows.

SQLiteConnection conn = new SQLiteConnection("Data Source=MyDatabase.sqlite;Version=3;");
conn.SetPassword("password");
conn.open();

then next time you can access it like

conn = new SQLiteConnection("Data Source=MyDatabase.sqlite;Version=3;Password=password;");
conn.Open();

This wont allow any GUI editor to view Your data. Later if you wish to change the password, use conn.ChangePassword("new_password"); To reset or remove password, use conn.ChangePassword(String.Empty);

char *arr; above statement implies that arr is a character pointer and it can point to either one character or strings of character

& char arr[]; above statement implies that arr is strings of character and can store as many characters as possible or even one but will always count on '\0' character hence making it a string ( e.g. char arr[]= "a" is similar to char arr[]={'a','\0'} )

But when used as parameters in called function, the string passed is stored character by character in formal arguments making no difference.

ROWS UNBOUNDED PRECEDING is no Teradata-specific syntax, it's Standard SQL. Together with the ORDER BY it defines the window on which the result is calculated.

Logically a Windowed Aggregate Function is newly calculated for each row within the PARTITION based on all ROWS between a starting row and an ending row.

Starting and ending rows might be fixed or relative to the current row based on the following keywords:

• CURRENT ROW, the current row
• UNBOUNDED PRECEDING, all rows before the current row -> fixed
• UNBOUNDED FOLLOWING, all rows after the current row -> fixed
• x PRECEDING, x rows before the current row -> relative
• y FOLLOWING, y rows after the current row -> relative

Possible kinds of calculation include:

• Both starting and ending row are fixed, the window consists of all rows of a partition, e.g. a Group Sum, i.e. aggregate plus detail rows
• One end is fixed, the other relative to current row, the number of rows increases or decreases, e.g. a Running Total, Remaining Sum
• Starting and ending row are relative to current row, the number of rows within a window is fixed, e.g. a Moving Average over n rows

So SUM(x) OVER (ORDER BY col ROWS UNBOUNDED PRECEDING) results in a Cumulative Sum or Running Total

11 -> 11
 2 -> 11 +  2                = 13
 3 -> 13 +  3 (or 11+2+3)    = 16
44 -> 16 + 44 (or 11+2+3+44) = 60

You can use pydoc.

Open your terminal and type python -m pydoc list.append

The advantage of pydoc over help() is that you do not have to import a module to look at its help text. For instance python -m pydoc random.randint.

Also you can start an HTTP server to interactively browse documentation by typing python -m pydoc -b (python 3)

For more information python -m pydoc

Check all the key and values in info.plist file. if any key is missing then it will cause this issue. AppIcon and other thing written in info.plist file must be prefect then u will not able to get this issue.

Greg's answer is right. Note that in Python 3.0 you'll have to do

sorted(dict.items())

as iteritems will be gone.

you can use linkbutton for navigating to another section in the same page by using PostBackUrl="#Section2"

I also put an answer there, but the article @Colonel Panic's update refers to suggests forcing TLS 1.2. In the future, when TLS 1.2 is compromised or just superceded, having your code stuck to TLS 1.2 will be considered a deficiency. Negotiation to TLS1.2 is enabled in .Net 4.6 by default. If you have the option to upgrade your source to .Net 4.6, I would highly recommend that change over forcing TLS 1.2.

If you do force TLS 1.2, strongly consider leaving some type of breadcrumb that will remove that force if you do upgrade to the 4.6 or higher framework.

I needed to use this as a cell function (like SUM or VLOOKUP) and found that it was easy to:

1. Make sure you are in a Macro Enabled Excel File (save as xlsm).
2. Open developer tools Alt + F11
3. Add Microsoft VBScript Regular Expressions 5.5 as in other answers

4. Create the following function either in workbook or in its own module:

   Function REGPLACE(myRange As Range, matchPattern As String, outputPattern As String) As Variant
       Dim regex As New VBScript_RegExp_55.RegExp
       Dim strInput As String
   
       strInput = myRange.Value
   
       With regex
           .Global = True
           .MultiLine = True
           .IgnoreCase = False
           .Pattern = matchPattern
       End With
   
       REGPLACE = regex.Replace(strInput, outputPattern)
   
   End Function
   

5. Then you can use in cell with =REGPLACE(B1, "(\w) (\d+)", "$1$2") (ex: "A 243" to "A243")

You can as well do:

git checkout --theirs /path/to/file

to keep the remote file, and:

git checkout --ours /path/to/file

to keep local file.

Then git add them and everything is done.

Edition: Keep in mind that this is for a merge scenario. During a rebase --theirs refers to the branch where you've been working.

My way to replicate Excel's MOD(a,b) in VBA is to use XLMod(a,b) in VBA where you include the function:

Function XLMod(a, b)
    ' This replicates the Excel MOD function
    XLMod = a - b * Int(a / b)
End Function

in your VBA Module

Just add water style="display:none"; to the <div>

Fiddles I say: http://jsfiddle.net/krY56/13/

jQuery:

function toggler(divId) {
    $("#" + divId).toggle();
}

Preferred to have a CSS Class .hidden

.hidden {
     display:none;
}

It might be most sensible to use multiprocessing.Pool which produces a pool of worker processes based on the max number of cores available on your system, and then basically feeds tasks in as the cores become available.

The example from the standard docs (http://docs.python.org/2/library/multiprocessing.html#using-a-pool-of-workers) shows that you can also manually set the number of cores:

from multiprocessing import Pool

def f(x):
    return x*x

if __name__ == '__main__':
    pool = Pool(processes=4)              # start 4 worker processes
    result = pool.apply_async(f, [10])    # evaluate "f(10)" asynchronously
    print result.get(timeout=1)           # prints "100" unless your computer is *very* slow
    print pool.map(f, range(10))          # prints "[0, 1, 4,..., 81]"

And it's also handy to know that there is the multiprocessing.cpu_count() method to count the number of cores on a given system, if needed in your code.

Edit: Here's some draft code that seems to work for your specific case:

import multiprocessing

def f(name):
    print 'hello', name

if __name__ == '__main__':
    pool = multiprocessing.Pool() #use all available cores, otherwise specify the number you want as an argument
    for i in xrange(0, 512):
        pool.apply_async(f, args=(i,))
    pool.close()
    pool.join()

The str function has a bug. Please try the following. You will see '0,196553' but the right output is '0,196554'. Because the str function's default value is ROUND_HALF_UP.

>>> value=0.196553500000 
>>> str("%f" % value).replace(".", ",")

If you're using CloudFoundry then you'd have to explicitly push the jar along with the keystore having the certificate.

Yes, SELECT from table_schema could be very usefull for system administration. If you have lot of servers, databases, tables... sometimes you need to DROP or UPDATE bunch of elements. For example to create query for DROP all tables with prefix name "wp_old_...":

SELECT concat('DROP TABLE ', table_name, ';') FROM INFORMATION_SCHEMA.TABLES
WHERE table_schema = '*name_of_your_database*'
AND table_name LIKE 'wp_old_%';

I see a number of answers using the Remove method and others using the Delete method.

Remove (according to the docs) will immediately remove the record from the (local) table, and on Update, will not remove a missing record.

Delete in comparison changes the RowState to Deleted, and will update the server table on Update. Likewise, calling the AcceptChanges method before the Update to the server table will reset all your RowState(s) to Unchanged and nothing will flow to the server. (Still nursing my thumb after hitting this a number of times).

Simple solution:

git rm --cached directory
git add directory

You can convert yourInt to bytes by using a ByteBuffer like this:

return ByteBuffer.allocate(4).putInt(yourInt).array();

Beware that you might have to think about the byte order when doing so.

I believe you must add the namespace to your xml document, with, for example, the use of a SAX filter.

That means:

• Define a ContentHandler interface with a new class which will intercept SAX events before JAXB can get them.
• Define a XMLReader which will set the content handler

then link the two together:

public static Object unmarshallWithFilter(Unmarshaller unmarshaller,
java.io.File source) throws FileNotFoundException, JAXBException 
{
    FileReader fr = null;
    try {
        fr = new FileReader(source);
        XMLReader reader = new NamespaceFilterXMLReader();
        InputSource is = new InputSource(fr);
        SAXSource ss = new SAXSource(reader, is);
        return unmarshaller.unmarshal(ss);
    } catch (SAXException e) {
        //not technically a jaxb exception, but close enough
        throw new JAXBException(e);
    } catch (ParserConfigurationException e) {
        //not technically a jaxb exception, but close enough
        throw new JAXBException(e);
    } finally {
        FileUtil.close(fr); //replace with this some safe close method you have
    }
}

There isn't really a standard name for this case convention, and there is disagreement over what it should be called.

That said, as of 2019, there is a strong case to be made that kebab-case is winning:

https://trends.google.com/trends/explore?date=all&q=kebab-case,spinal-case,lisp-case,dash-case,caterpillar-case

spinal-case is a distant second, and no other terms have any traction at all.

Additionally, kebab-case has entered the lexicon of several javascript code libraries, e.g.:

• https://lodash.com/docs/#kebabCase
• https://www.npmjs.com/package/kebab-case
• https://vuejs.org/v2/guide/components-props.html#Prop-Casing-camelCase-vs-kebab-case

However, there are still other terms that people use. Lisp has used this convention for decades as described in this Wikipedia entry, so some people have described it as lisp-case. Some other forms I've seen include caterpillar-case, dash-case, and hyphen-case, but none of these is standard.

So the answer to your question is: No, there isn't a single widely-accepted name for this case convention analogous to snake_case or camelCase, which are widely-accepted.

Another example when the table name or database contains unsupported characters such as a space, or '-'

db='data-base'

db_d=''
db_d+='`'
db_d+=$db
db_d+='`'

myvariable=`mysql --user=$user --password=$password -e "SELECT A, B, C FROM $db_d.table_a;"`

There's this library GeoCoordinate for these platforms:

• Mono
• .NET 4.5
• .NET Core
• Windows Phone 8.x
• Universal Windows Platform
• Xamarin iOS
• Xamarin Android

Installation is done via NuGet:

PM> Install-Package GeoCoordinate

Usage

GeoCoordinate pin1 = new GeoCoordinate(lat, lng);
GeoCoordinate pin2 = new GeoCoordinate(lat, lng);

double distanceBetween = pin1.GetDistanceTo(pin2);

The distance between the two coordinates, in meters.

To my knowledge, which, to be fair, is fairly new and limited, the only potential issue with this technique is the fact that you are prevented from dynamically creating some table elements.

I use a form to templating by adding "template" elements to a hidden DIV and then using cloneNode(true) to create a clone and appending it as required. Bear in ind that you do need to ensure you re-assign id's as required to prevent duplication.

Using PostgreSQL like (see accepted answer above) somehow didn't work for me although cases matched, but ilike (case insensisitive like) does.

Java 7 support was added at build tools 19. You can now use features like the diamond operator, multi-catch, try-with-resources, strings in switches, etc. Add the following to your build.gradle.

android {
    compileSdkVersion 19
    buildToolsVersion "19.0.0"

    defaultConfig {
        minSdkVersion 7
        targetSdkVersion 19
    }

    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_7
        targetCompatibility JavaVersion.VERSION_1_7
    }
}

Gradle 1.7+, Android gradle plugin 0.6.+ are required.

Note, that only try with resources require minSdkVersion 19. Other features works on previous platforms.

If the image has big dimenssions is hard to get good results without resizing, below is a 60 percent resizing which for most of the purposes doesn't destroys too much of the image.

I use this with good result for gray-scale images (I convert from PNG):

ls ./*.png | xargs -L1 -I {} convert {} -strip -interlace JPEG -sampling-factor 4:2:0 -adaptive-resize 60%   -gaussian-blur 0.05 -colorspace Gray -quality 20  {}.jpg

I use this for scanned B&W pages get them to gray-scale images (the extra arguments cleans shadows from previous pages):

ls ./*.png | xargs -L1 -I {} convert {} -strip -interlace JPEG -sampling-factor 4:2:0 -adaptive-resize 60%   -gaussian-blur 0.05 -colorspace Gray -quality 20 -density 300 -fill white -fuzz 40% +opaque "#000000" -density 300 {}.jpg 

I use this for color images:

ls ./*.png | xargs -L1 -I {} convert {} -strip -interlace JPEG -sampling-factor 4:2:0 -adaptive-resize 60%   -gaussian-blur 0.05 -colorspace RGB -quality 20  {}.jpg 

    let path = window.location.href;
    $('#nav li a').each(function() {
        if (this.href === path) {
            $(this).addClass('activo');
        }else{
            $(this).removeClass('activo')
        }
        
    })
    

If the header file is /usr/include/sdl/SDL.h and your code has:

#include "SDL.h"

You need to either fix your code:

#include "sdl/SDL.h"

Or tell the preprocessor where to find include files:

CFLAGS = ... -I/usr/include/sdl ...

upstream defines a cluster that you can proxy requests to. It's commonly used for defining either a web server cluster for load balancing, or an app server cluster for routing / load balancing.

Use this function, the first argument is the url to the folder, the second is the place the folder will be downloaded to:

function github-dir() {
    svn export "$(sed 's/tree\/master/trunk/' <<< "$1")" "$2"  
}

This is a better method :-

void main()throws IOException
{
    System.out.println("Enter sentence");
    BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
    String str = br.readLine();
    String sentence = "";
    for(int i=0;i<str.length();i++)
    {
        if(Character.isUpperCase(str.charAt(i))==true)
        {
            char ch2= (char)(str.charAt(i)+32);
            sentence = sentence + ch2;
        }
        else if(Character.isLowerCase(str.charAt(i))==true)
        {
            char ch2= (char)(str.charAt(i)-32);
            sentence = sentence + ch2;
        }
        else
        sentence= sentence + str.charAt(i);

    }
    System.out.println(sentence);
}

This does not work in Chrome Developer tools to locate a element, i am looking to locate the 'Submit' button in the screen

//input[matches(@value,'submit','i')]

However, using 'translate' to replace all caps to small works as below

//input[translate(@value,'ABCDEFGHIJKLMNOPQRSTUVWXYZ','abcdefghijklmnopqrstuvwxyz') = 'submit']

Update: I just found the reason why 'matches' doesnt work. I am using Chrome with xpath 1.0 which wont understand the syntax 'matches'. It should be xpath 2.0

I agree with @annakata that this question needs some more clarification, but here is a very, very basic example of how to setup an onclick event handler for the radio buttons:

<html>
 <head>
  <script type="text/javascript">
    window.onload = function() {

        var ex1 = document.getElementById('example1');
        var ex2 = document.getElementById('example2');
        var ex3 = document.getElementById('example3');

        ex1.onclick = handler;
        ex2.onclick = handler;
        ex3.onclick = handler;

    }

    function handler() {
        alert('clicked');
    }
  </script>
 </head>
 <body>
  <input type="radio" name="example1" id="example1" value="Example 1" />
  <label for="example1">Example 1</label>
  <input type="radio" name="example2" id="example2" value="Example 2" />
  <label for="example1">Example 2</label>
  <input type="radio" name="example3" id="example3" value="Example 3" />
  <label for="example1">Example 3</label>
 </body>
</html>

I know this is an old question, but it might be worth mentioning that you can create your own configurations outside of DEBUG and RELEASE, such as TEST or UAT.

If then on the Build tab of the project properties page you then set the "Conditional compilation symbols" to TEST (for instance) you can then use a construct such as

#if (DEBUG || TEST )
    //Code that will not be executed in RELEASE or UAT
#endif

You can use this construct for specific reason such as different clients if you have the need, or even entire Web Methods for instance. We have also used this in the past where some commands have caused issues on specific hardware, so we have a configuration for an app when deployed to hardware X.

There is no rate of growth from 0 to any other number. That is to say, there is no percentage of increase from zero to greater than zero and there is no percentage of decrease from zero to less than zero (a negative number). What you have to decide is what to put as an output when this situation happens. Here are two possibilities I am comfortable with:

1. Any time you have to show a rate of increase from zero, output the infinity symbol (8). That's Alt + 236 on your number pad, in case you're wondering. You could also use negative infinity (-8) for a negative growth rate from zero.
2. Output a statement such as "[Increase/Decrease] From Zero" or something along those lines.

Unfortunately, if you need the growth rate for further calculations, the above options will not work, but, on the other hand, any number would give your following calculations incorrect data any way so the point is moot. You'd need to update your following calculations to account for this eventuality.

As an aside, the ((New-Old)/Old) function will not work when your new and old values are both zero. You should create an initial check to see if both values are zero and, if they are, output zero percent as the growth rate.

In later versions of JQuery they have changed the function from select to activate. http://api.jqueryui.com/tabs/#event-activate

Matlab allows you to return multiple values as well as receive them inline.

When you call it, receive individual variables inline:

[array, listp, freep] = initialize(size)

This is useful to check the status of autocommit;

select @@autocommit;

On RHEL 6 this worked for me also:

umount -f -a -t cifs -l FOLDER_NAME

1. Can I replace the toggle text with an image

   No, we can not, although we can hide the text by overiding the default style of the toggle button, but still that won't give us a toggle button you want as we can't replace the text with an image.

2. How can I make a normal toggle button

   Create a file ic_toggle in your res/drawable folder

   <selector xmlns:android="http://schemas.android.com/apk/res/android">
   
       <item android:state_checked="false"
             android:drawable="@drawable/ic_slide_switch_off" />
   
       <item android:state_checked="true"
             android:drawable="@drawable/ic_slide_switch_on" />
   
   </selector>
   

   Here @drawable/ic_slide_switch_on & @drawable/ic_slide_switch_off are images you create.

   Then create another file in the same folder, name it ic_toggle_bg

   <?xml version="1.0" encoding="utf-8"?>
   <layer-list xmlns:android="http://schemas.android.com/apk/res/android">
   
       <item android:id="@+android:id/background"  
             android:drawable="@android:color/transparent" />
   
       <item android:id="@+android:id/toggle"
             android:drawable="@drawable/ic_toggle" />
   
   </layer-list>
   

   Now add to your custom theme, (if you do not have one create a styles.xml file in your res/values/folder)

   <style name="Widget.Button.Toggle" parent="android:Widget">
      <item name="android:background">@drawable/ic_toggle_bg</item>
      <item name="android:disabledAlpha">?android:attr/disabledAlpha</item>
   </style>
   
   <style name="toggleButton"  parent="@android:Theme.Black">
      <item name="android:buttonStyleToggle">@style/Widget.Button.Toggle</item>
      <item name="android:textOn"></item>
      <item name="android:textOff"></item>
   </style>
   

   This creates a custom toggle button for you.

3. How to use it

   Use the custom style and background in your view.

     <ToggleButton
           android:id="@+id/toggleButton"
           android:layout_width="wrap_content"
           android:layout_height="match_parent"
           android:layout_gravity="right"
           style="@style/toggleButton"
           android:background="@drawable/ic_toggle_bg"/>
   

NSString *folderName=[NSString stringWithFormat:@"/documents/%@",[tempDictLitrature objectForKey:@"folder"]];
NSString *fileName=[tempDictLitrature objectForKey:@"name"];
[self.navigationItem setTitle:fileName];
NSString *type=[tempDictLitrature objectForKey:@"type"];

NSString *path=[[NSBundle mainBundle]pathForResource:fileName ofType:type inDirectory:folderName];

NSURL *targetURL = [NSURL fileURLWithPath:path];
NSURLRequest *request = [NSURLRequest requestWithURL:targetURL];
webView=[[UIWebView alloc] initWithFrame:CGRectMake(0, 0, 1024, 730)];
[webView setBackgroundColor:[UIColor lightGrayColor]];
webView.scalesPageToFit = YES;

[[webView scrollView] setContentOffset:CGPointZero animated:YES];
[webView stringByEvaluatingJavaScriptFromString:[NSString stringWithFormat:@"window.scrollTo(0.0, 50.0)"]];
[webView loadRequest:request];
[self.view addSubview:webView];

For swift 4 and you can adjust imageView size

 let logoContainer = UIView(frame: CGRect(x: 0, y: 0, width: 270, height: 30))

 let imageView = UIImageView(frame: CGRect(x: 0, y: 0, width: 270, height: 30))
 imageView.contentMode = .scaleAspectFit
 let image = UIImage(named: "your_image")
 imageView.image = image
 logoContainer.addSubview(imageView)
 navigationItem.titleView = logoContainer

just use pow(a,b),which is exactly 3**4 in python

To make it easier to get the fully qualified name of a class in order to create an instance using Class.forName(...), one could use the Class.getName() method. Something like:

class ObjectMaker {
    // Constructor, fields, initialization, etc...
    public Object makeObject(Class<?> clazz) {
        Object o = null;

        try {
            o = Class.forName(clazz.getName()).newInstance();
        } catch (ClassNotFoundException e) {
            // There may be other exceptions to throw here, 
            // but I'm writing this from memory.
            e.printStackTrace();
        }

        return o;
    }
}

Then you can cast the object you get back to whatever class you pass to makeObject(...):

Data d = (Data) objectMaker.makeObject(Data.class);

The answer from las3rjock, which somehow is the answer accepted by the OP, is incorrect--the code doesn't run, nor is it valid matplotlib syntax; that answer provides no runnable code and lacks any information or suggestion that the OP might find useful in writing their own code to solve the problem in the OP.

Given that it's the accepted answer and has already received several up-votes, I suppose a little deconstruction is in order.

First, calling subplot does not give you multiple plots; subplot is called to create a single plot, as well as to create multiple plots. In addition, "changing plt.figure(i)" is not correct.

plt.figure() (in which plt or PLT is usually matplotlib's pyplot library imported and rebound as a global variable, plt or sometimes PLT, like so:

from matplotlib import pyplot as PLT

fig = PLT.figure()

the line just above creates a matplotlib figure instance; this object's add_subplot method is then called for every plotting window (informally think of an x & y axis comprising a single subplot). You create (whether just one or for several on a page), like so

fig.add_subplot(111)

this syntax is equivalent to

fig.add_subplot(1,1,1)

choose the one that makes sense to you.

Below I've listed the code to plot two plots on a page, one above the other. The formatting is done via the argument passed to add_subplot. Notice the argument is (211) for the first plot and (212) for the second.

from matplotlib import pyplot as PLT

fig = PLT.figure()

ax1 = fig.add_subplot(211)
ax1.plot([(1, 2), (3, 4)], [(4, 3), (2, 3)])

ax2 = fig.add_subplot(212)
ax2.plot([(7, 2), (5, 3)], [(1, 6), (9, 5)])

PLT.show()

Each of these two arguments is a complete specification for correctly placing the respective plot windows on the page.

211 (which again, could also be written in 3-tuple form as (2,1,1) means two rows and one column of plot windows; the third digit specifies the ordering of that particular subplot window relative to the other subplot windows--in this case, this is the first plot (which places it on row 1) hence plot number 1, row 1 col 1.

The argument passed to the second call to add_subplot, differs from the first only by the trailing digit (a 2 instead of a 1, because this plot is the second plot (row 2, col 1).

An example with more plots: if instead you wanted four plots on a page, in a 2x2 matrix configuration, you would call the add_subplot method four times, passing in these four arguments (221), (222), (223), and (224), to create four plots on a page at 10, 2, 8, and 4 o'clock, respectively and in this order.

Notice that each of the four arguments contains two leadings 2's--that encodes the 2 x 2 configuration, ie, two rows and two columns.

The third (right-most) digit in each of the four arguments encodes the ordering of that particular plot window in the 2 x 2 matrix--ie, row 1 col 1 (1), row 1 col 2 (2), row 2 col 1 (3), row 2 col 2 (4).

According to the Git Cheatsheet you have to create the branch first

git branch [branchName]

and then

git checkout [branchName]

You can go up a folder in the hierarchy by using

../

So to get to folder /webroot/site/pages/folder2/mypage.htm from /webroot/site/pages/folder1/myotherpage.htm your link would look like this:

<a href="../folder2/mypage.htm">Link to My Page</a>

If You have no access to plugin for instance outside of controller You can get params from servicelocator like this

//from POST
$foo = $this->serviceLocator->get('request')->getPost('foo'); 
//from GET
$foo = $this->serviceLocator->get('request')->getQuery()->foo;
//from route
$foo = $this->serviceLocator->get('application')->getMvcEvent()->getRouteMatch()->getParam('foo');

$(".datepicker").datepicker({maxDate: '0'});

This will set the maxDate to +0 days from the current date (i.e. today). See:

http://api.jqueryui.com/datepicker/#option-maxDate

I get the code to generate the PDF from html template :

    import os

    from weasyprint import HTML

    from django.template import Template, Context
    from django.http import HttpResponse 


    def generate_pdf(self, report_id):

            # Render HTML into memory and get the template firstly
            template_file_loc = os.path.join(os.path.dirname(__file__), os.pardir, 'templates', 'the_template_pdf_generator.html')
            template_contents = read_all_as_str(template_file_loc)
            render_template = Template(template_contents)

            #rendering_map is the dict for params in the template 
            render_definition = Context(rendering_map)
            render_output = render_template.render(render_definition)

            # Using Rendered HTML to generate PDF
            response = HttpResponse(content_type='application/pdf')
            response['Content-Disposition'] = 'attachment; filename=%s-%s-%s.pdf' % \
                                              ('topic-test','topic-test', '2018-05-04')
            # Generate PDF
            pdf_doc = HTML(string=render_output).render()
            pdf_doc.pages[0].height = pdf_doc.pages[0]._page_box.children[0].children[
                0].height  # Make PDF file as single page file 
            pdf_doc.write_pdf(response)
            return response

    def read_all_as_str(self, file_loc, read_method='r'):
        if file_exists(file_loc):
            handler = open(file_loc, read_method)
            contents = handler.read()
            handler.close()
            return contents
        else:
            return 'file not exist'  

choose a low resolution emulator (eg: Nexus S) if you don't have a good graphic card (like me)

I used AndExplorer for this purpose and my solution is popup a dialog and then redirect on the market to install the misssing application:

My startCreation is trying to call external file/directory picker. If it is missing call show installResultMessage function.

private void startCreation(){
    Intent intent = new Intent();
    intent.setAction(Intent.ACTION_PICK);
    Uri startDir = Uri.fromFile(new File("/sdcard"));

    intent.setDataAndType(startDir,
            "vnd.android.cursor.dir/lysesoft.andexplorer.file");
    intent.putExtra("browser_filter_extension_whitelist", "*.csv");
    intent.putExtra("explorer_title", getText(R.string.andex_file_selection_title));
    intent.putExtra("browser_title_background_color",
            getText(R.string.browser_title_background_color));
    intent.putExtra("browser_title_foreground_color",
            getText(R.string.browser_title_foreground_color));
    intent.putExtra("browser_list_background_color",
            getText(R.string.browser_list_background_color));
    intent.putExtra("browser_list_fontscale", "120%");
    intent.putExtra("browser_list_layout", "2");

    try{
         ApplicationInfo info = getPackageManager()
                                 .getApplicationInfo("lysesoft.andexplorer", 0 );

            startActivityForResult(intent, PICK_REQUEST_CODE);
    } catch( PackageManager.NameNotFoundException e ){
        showInstallResultMessage(R.string.error_install_andexplorer);
    } catch (Exception e) {
        Log.w(TAG, e.getMessage());
    }
}

This methos is just pick up a dialog and if user wants install the external application from market

private void showInstallResultMessage(int msg_id) {
    AlertDialog dialog = new AlertDialog.Builder(this).create();
    dialog.setMessage(getText(msg_id));
    dialog.setButton(getText(R.string.button_ok),
            new DialogInterface.OnClickListener() {

                @Override
                public void onClick(DialogInterface dialog, int which) {
                    finish();
                }
            });
    dialog.setButton2(getText(R.string.button_install),
            new DialogInterface.OnClickListener() {

                @Override
                public void onClick(DialogInterface dialog, int which) {
                    Intent intent = new Intent(Intent.ACTION_VIEW);
                    intent.setData(Uri.parse("market://details?id=lysesoft.andexplorer"));
                    startActivity(intent);
                    finish();
                }
            });
    dialog.show();
}

Depending on the version you are running. It is basically the same just go to
File -> Invalidate caches, then restart Intellij
or
File -> Invalidate caches / Restart

The main difference is that in older versions you had to manually restart as cache files are not removed until you restart. The newer versions will ask if you also want to restart.

As seen here on this official Jetbrains help page

You can also try delete caches manually in the system folder for your installed version. The location of this folder depends on your OS and version installed.

Windows Vista, 7, 8, 10
<SYSTEM DRIVE>\Users\<USER ACCOUNT NAME>\.<PRODUCT><VERSION>

Linux/Unix
~/.<PRODUCT><VERSION>

Mac OS
~/Library/Caches/<PRODUCT><VERSION>

Read this for more details on cache locations.

from datetime import datetime

a = datetime.strptime(f, "%Y-%m-%d")

Try

checkbox1.onclick= e => {
  if(!checkbox1.checked) checkbox1.checked = !confirm("Are you sure?");
  textbox1.value = checkbox1.checked;
}

<input type="checkbox" id="checkbox1" /><br />
<input type="text" id="textbox1" value='false'/>

In Global.asax.cs, Application_Start() method add:

DataAnnotationsModelValidatorProvider.RegisterAdapter(typeof(MyRequiredAttribute), typeof(RequiredAttributeAdapter));

Simple tabulation of the output:

a = 0.3333333
b = 200/3
print("variable a    variable b")
print("%10.2f    %10.2f" % (a, b))

output:

variable a    variable b
      0.33         66.67

%10.2f: 10 is the minimum length and 2 is the number of decimal places.

You can use GroupBy with anonymous type, and then get First:

list.GroupBy(e => new { 
                          empLoc = e.empLoc, 
                          empPL = e.empPL, 
                          empShift = e.empShift 
                       })

    .Select(g => g.First());

Of course, just assign seperate css classes to both tables.

<table class="style1"></table>
<table class="style2"></table>

.css

table.style1 { //your css here}
table.style2 { //your css here}

Take a look at this video

All what you have to do is to select your file (assuming it's same simple form of txt file), then drag it to the project in Eclipse and then drop it there. Choose Copy instead of Link as it's more flexible. That's it - I just tried that.

If ever you need to do the same thing with mongoid:

Model.all.rename(:old_field, :new_field)

UPDATE

There is change in the syntax in monogoid 4.0.0:

Model.all.rename(old_field: :new_field)

A "sort merge" join is performed by sorting the two data sets to be joined according to the join keys and then merging them together. The merge is very cheap, but the sort can be prohibitively expensive especially if the sort spills to disk. The cost of the sort can be lowered if one of the data sets can be accessed in sorted order via an index, although accessing a high proportion of blocks of a table via an index scan can also be very expensive in comparison to a full table scan.

A hash join is performed by hashing one data set into memory based on join columns and reading the other one and probing the hash table for matches. The hash join is very low cost when the hash table can be held entirely in memory, with the total cost amounting to very little more than the cost of reading the data sets. The cost rises if the hash table has to be spilled to disk in a one-pass sort, and rises considerably for a multipass sort.

(In pre-10g, outer joins from a large to a small table were problematic performance-wise, as the optimiser could not resolve the need to access the smaller table first for a hash join, but the larger table first for an outer join. Consequently hash joins were not available in this situation).

The cost of a hash join can be reduced by partitioning both tables on the join key(s). This allows the optimiser to infer that rows from a partition in one table will only find a match in a particular partition of the other table, and for tables having n partitions the hash join is executed as n independent hash joins. This has the following effects:

1. The size of each hash table is reduced, hence reducing the maximum amount of memory required and potentially removing the need for the operation to require temporary disk space.
2. For parallel query operations the amount of inter-process messaging is vastly reduced, reducing CPU usage and improving performance, as each hash join can be performed by one pair of PQ processes.
3. For non-parallel query operations the memory requirement is reduced by a factor of n, and the first rows are projected from the query earlier.

You should note that hash joins can only be used for equi-joins, but merge joins are more flexible.

In general, if you are joining large amounts of data in an equi-join then a hash join is going to be a better bet.

This topic is very well covered in the documentation.

This should do the trick

var start = $('#start_date').val();
var end = $('#end_date').val();

// end - start returns difference in milliseconds 
var diff = new Date(end - start);

// get days
var days = diff/1000/60/60/24;

Example

var start = new Date("2010-04-01"),
    end   = new Date(),
    diff  = new Date(end - start),
    days  = diff/1000/60/60/24;

Try update your Eclipse with the newest Maven repository as follows:

1. Open "Install" dialog box by choosing "Help/Install New Software..." in Eclipse
2. Insert following link into "Work with:" input box http://download.eclipse.org/technology/m2e/releases/
   and press Enter
3. Select (check) "Maven Integration for Eclipse" and choose "Next >" button
4. Continue with the installation, confirm the License agreement, let the installation download what is necessary
5. After successful installation you should restart Eclipse
6. Your project should be loaded without Maven-related errors now

You could simply do:

Select Req_ID, (avg(R1)+avg(R2)+avg(R3)+avg(R4)+avg(R5))/5 as Average
from Request
Group by Req_ID

Right?

I'm assuming that you may have multiple rows with the same Req_ID and in these cases you want to calculate the average across all columns and rows for those rows with the same Req_ID

Two years late, but I have the solution you're looking for. Not intending to take credit form the original author, here's a plugin which I found works exceptionally well for what you need, but gets all possible styles in all browsers, even IE.

Warning: This code generates a lot of output, and should be used sparingly. It not only copies all standard CSS properties, but also all vendor CSS properties for that browser.

jquery.getStyleObject.js:

/*
 * getStyleObject Plugin for jQuery JavaScript Library
 * From: http://upshots.org/?p=112
 */

(function($){
    $.fn.getStyleObject = function(){
        var dom = this.get(0);
        var style;
        var returns = {};
        if(window.getComputedStyle){
            var camelize = function(a,b){
                return b.toUpperCase();
            };
            style = window.getComputedStyle(dom, null);
            for(var i = 0, l = style.length; i < l; i++){
                var prop = style[i];
                var camel = prop.replace(/\-([a-z])/g, camelize);
                var val = style.getPropertyValue(prop);
                returns[camel] = val;
            };
            return returns;
        };
        if(style = dom.currentStyle){
            for(var prop in style){
                returns[prop] = style[prop];
            };
            return returns;
        };
        return this.css();
    }
})(jQuery);

Basic usage is pretty simple, but he's written a function for that as well:

$.fn.copyCSS = function(source){
  var styles = $(source).getStyleObject();
  this.css(styles);
}

Hope that helps.

Another way to view it is to open IE, then click on the "gear" icon, then Internet options -> Connections tab -> click on LAN settings

Also make sure you check the vendors website for their "USB" drivers. I had this problem with my AT&T Galaxy Note (Running Android 2.3.6) and it wasn't being recognized by the adb without a driver install that I got from the samsung website.

I had this issue for longer than I would like to admit.

I simply just needed to run VS as an administrator, rookie mistake on my part...

Hope this helps someone <3

I wonder why no one added the alternative of using the function chr():

echo 'Hello World!' . chr(10);

or, more efficient if you're going to repeat it a million times:

define('C_NewLine', chr(10));
...
echo 'Hello World!' . C_NewLine;

This avoids the silly-looking notation of concatenating a single- and double-quoted string.

This error would suggest that User::where('email', '=', $userEmail)->first() is returning null, rather than a problem with updating your model.

Check that you actually have a User before attempting to change properties on it, or use the firstOrFail() method.

$UpdateDetails = User::where('email', $userEmail)->first();

if (is_null($UpdateDetails)) {
    return false;
}

or using the firstOrFail() method, theres no need to check if the user is null because this throws an exception (ModelNotFoundException) when a model is not found, which you can catch using App::error() http://laravel.com/docs/4.2/errors#handling-errors

$UpdateDetails = User::where('email', $userEmail)->firstOrFail();

{ } -->

defines scope, so if(a==1) { int b = 10; } says, you are defining int b, for {}- this scope. For

if(a==1)
  int b =10;

there is no scope. And you will not be able to use b anywhere.

What is RMSE? Also known as MSE, RMD, or RMS. What problem does it solve?

If you understand RMSE: (Root mean squared error), MSE: (Mean Squared Error) RMD (Root mean squared deviation) and RMS: (Root Mean Squared), then asking for a library to calculate this for you is unnecessary over-engineering. All these metrics are a single line of python code at most 2 inches long. The three metrics rmse, mse, rmd, and rms are at their core conceptually identical.

RMSE answers the question: "How similar, on average, are the numbers in list1 to list2?". The two lists must be the same size. I want to "wash out the noise between any two given elements, wash out the size of the data collected, and get a single number feel for change over time".

Intuition and ELI5 for RMSE:

Imagine you are learning to throw darts at a dart board. Every day you practice for one hour. You want to figure out if you are getting better or getting worse. So every day you make 10 throws and measure the distance between the bullseye and where your dart hit.

You make a list of those numbers list1. Use the root mean squared error between the distances at day 1 and a list2 containing all zeros. Do the same on the 2nd and nth days. What you will get is a single number that hopefully decreases over time. When your RMSE number is zero, you hit bullseyes every time. If the rmse number goes up, you are getting worse.

Example in calculating root mean squared error in python:

import numpy as np
d = [0.000, 0.166, 0.333]   #ideal target distances, these can be all zeros.
p = [0.000, 0.254, 0.998]   #your performance goes here

print("d is: " + str(["%.8f" % elem for elem in d]))
print("p is: " + str(["%.8f" % elem for elem in p]))

def rmse(predictions, targets):
    return np.sqrt(((predictions - targets) ** 2).mean())

rmse_val = rmse(np.array(d), np.array(p))
print("rms error is: " + str(rmse_val))

Which prints:

d is: ['0.00000000', '0.16600000', '0.33300000']
p is: ['0.00000000', '0.25400000', '0.99800000']
rms error between lists d and p is: 0.387284994115

The mathematical notation:

Glyph Legend: n is a whole positive integer representing the number of throws. i represents a whole positive integer counter that enumerates sum. d stands for the ideal distances, the list2 containing all zeros in above example. p stands for performance, the list1 in the above example. superscript 2 stands for numeric squared. d_i is the i'th index of d. p_i is the i'th index of p.

The rmse done in small steps so it can be understood:

def rmse(predictions, targets):

    differences = predictions - targets                       #the DIFFERENCEs.

    differences_squared = differences ** 2                    #the SQUAREs of ^

    mean_of_differences_squared = differences_squared.mean()  #the MEAN of ^

    rmse_val = np.sqrt(mean_of_differences_squared)           #ROOT of ^

    return rmse_val                                           #get the ^

How does every step of RMSE work:

Subtracting one number from another gives you the distance between them.

8 - 5 = 3         #absolute distance between 8 and 5 is +3
-20 - 10 = -30    #absolute distance between -20 and 10 is +30

If you multiply any number times itself, the result is always positive because negative times negative is positive:

3*3     = 9   = positive
-30*-30 = 900 = positive

Add them all up, but wait, then an array with many elements would have a larger error than a small array, so average them by the number of elements.

But wait, we squared them all earlier to force them positive. Undo the damage with a square root!

That leaves you with a single number that represents, on average, the distance between every value of list1 to it's corresponding element value of list2.

If the RMSE value goes down over time we are happy because variance is decreasing.

RMSE isn't the most accurate line fitting strategy, total least squares is:

Root mean squared error measures the vertical distance between the point and the line, so if your data is shaped like a banana, flat near the bottom and steep near the top, then the RMSE will report greater distances to points high, but short distances to points low when in fact the distances are equivalent. This causes a skew where the line prefers to be closer to points high than low.

If this is a problem the total least squares method fixes this: https://mubaris.com/posts/linear-regression

Gotchas that can break this RMSE function:

If there are nulls or infinity in either input list, then output rmse value is is going to not make sense. There are three strategies to deal with nulls / missing values / infinities in either list: Ignore that component, zero it out or add a best guess or a uniform random noise to all timesteps. Each remedy has its pros and cons depending on what your data means. In general ignoring any component with a missing value is preferred, but this biases the RMSE toward zero making you think performance has improved when it really hasn't. Adding random noise on a best guess could be preferred if there are lots of missing values.

In order to guarantee relative correctness of the RMSE output, you must eliminate all nulls/infinites from the input.

RMSE has zero tolerance for outlier data points which don't belong

Root mean squared error squares relies on all data being right and all are counted as equal. That means one stray point that's way out in left field is going to totally ruin the whole calculation. To handle outlier data points and dismiss their tremendous influence after a certain threshold, see Robust estimators that build in a threshold for dismissal of outliers.

Use boolean rather than Boolean every time you can. This will avoid many NullPointerExceptions and make your code more robust.

Boolean is useful, for example

• to store booleans in a collection (List, Map, etc.)
• to represent a nullable boolean (coming from a nullable boolean column in a database, for example). The null value might mean "we don't know if it's true or false" in this context.
• each time a method needs an Object as argument, and you need to pass a boolean value. For example, when using reflection or methods like MessageFormat.format().

You can try below code:

$("Your button id or class").live("click", function(){

    $('#detailInfo').html('set your value as you want');

});

Good Luck...

Just for posterity, here's the text from several external sources regarding the Excel file formats. Some of these have been mentioned in other answers to this question but without reproducing the essential content.

1. From Doug Mahugh, August 22, 2006:

...the new XLSB binary format. Like Open XML, it’s a full-fidelity file format that can store anything you can create in Excel, but the XLSB format is optimized for performance in ways that aren’t possible with a pure XML format.

The XLSB format (also sometimes referred to as BIFF12, as in “binary file format for Office 12”) uses the same Open Packaging Convention used by the Open XML formats and XPS. So it’s basically a ZIP container, and you can open it with any ZIP tool to see what’s inside. But instead of .XML parts within the package, you’ll find .BIN parts...

This article also refers to documentation about the BIN format, too lengthy to reproduce here.

2. From MSDN Archive, August 29, 2006 which in turn cites an already-missing blog post regarding the XLSB format:

Even though we’ve done a lot of work to make sure that our XML formats open quickly and efficiently, this binary format is still more efficient for Excel to open and save, and can lead to some performance improvements for workbooks that contain a lot of data, or that would require a lot of XML parsing during the Open process. (In fact, we’ve found that the new binary format is faster than the old XLS format in many cases.) Also, there is no macro-free version of this file format – all XLSB files can contain macros (VBA and XLM). In all other respects, it is functionally equivalent to the XML file format above:

File size – file size of both formats is approximately the same, since both formats are saved to disk using zip compression Architecture – both formats use the same packaging structure, and both have the same part-level structures. Feature support – both formats support exactly the same feature set Runtime performance – once loaded into memory, the file format has no effect on application/calculation speed Converters – both formats will have identical converter support
