Here's an iterator-based method.

ifstream file("file", ios::binary);
string fileStr;

istreambuf_iterator<char> inputIt(file), emptyInputIt
back_insert_iterator<string> stringInsert(fileStr);

copy(inputIt, emptyInputIt, stringInsert);

In the example you give, you're perfectly right, you have to set the title attribute.

If the aria-label is one tool used by assistive technologies (like screen readers), it is not natively supported on browsers and has no effect on them. It won't be of any help to most of the people targetted by the WCAG (except screen reader users), for instance a person with intellectal disabilities.

The "X" is not sufficient enough to give information to the action led by the button (think about someone with no computer knowledge). It might mean "close", "delete", "cancel", "reduce", a strange cross, a doodle, nothing.

Despite the fact that the W3C seems to promote the aria-label rather that the title attribute here: http://www.w3.org/TR/2014/NOTE-WCAG20-TECHS-20140916/ARIA14 in a similar example, you can see that the technology support does not include standard browsers : http://www.w3.org/WAI/WCAG20/Techniques/ua-notes/aria#ARIA14

In fact aria-label, in this exact situation might be used to give more context to an action:

For instance, blind people do not perceive popups like those of us with good vision, it's like a change of context. "Back to the page" will be a more convenient alternative for a screen reader, when "Close" is more significant for someone with no screen reader.

  <button
      aria-label="Back to the page"
      title="Close" onclick="myDialog.close()">X</button>

Try this:

HTML:

<input type="checkbox" value="FALSE" />

jQ:

$("input[type='checkbox']").on('change', function(){
  $(this).val(this.checked ? "TRUE" : "FALSE");
})

jsfiddle

Please bear in mind that unchecked checkbox will not be submitted in regular form, and you should use hidden filed in order to do it.

The problem in my case was that the "receiver mountpoint" was incorrectly mounted. It was in read-only mode (for some extrange reason). It looked like rsync was copying the files, but it was not. I checked my fstab file and changed mount options to default, re-mount file system and execute rsync again. All fine then.

This works really well:

<td><div style = "width:80px; word-wrap: break-word"> your text </div></td> 

You can use the same width for all your <div's, or adjust the width in each case to break your text wherever you like.

This way you do not have to fool around with fixed table widths, or complex css.

According to the RFC that introduced the operator, $a <=> $b evaluates to:

• 0 if $a == $b
• -1 if $a < $b
• 1 if $a > $b

which seems to be the case in practice in every scenario I've tried, although strictly the official docs only offer the slightly weaker guarantee that $a <=> $b will return

an integer less than, equal to, or greater than zero when $a is respectively less than, equal to, or greater than $b

Regardless, why would you want such an operator? Again, the RFC addresses this - it's pretty much entirely to make it more convenient to write comparison functions for usort (and the similar uasort and uksort).

usort takes an array to sort as its first argument, and a user-defined comparison function as its second argument. It uses that comparison function to determine which of a pair of elements from the array is greater. The comparison function needs to return:

an integer less than, equal to, or greater than zero if the first argument is considered to be respectively less than, equal to, or greater than the second.

The spaceship operator makes this succinct and convenient:

$things = [
    [
        'foo' => 5.5,
        'bar' => 'abc'
    ],
    [
        'foo' => 7.7,
        'bar' => 'xyz'
    ],
    [
        'foo' => 2.2,
        'bar' => 'efg'
    ]
];

// Sort $things by 'foo' property, ascending
usort($things, function ($a, $b) {
    return $a['foo'] <=> $b['foo'];
});

// Sort $things by 'bar' property, descending
usort($things, function ($a, $b) {
    return $b['bar'] <=> $a['bar'];
});

More examples of comparison functions written using the spaceship operator can be found in the Usefulness section of the RFC.

Even though you define android:onClick = "DoIt" in XML, you need to make sure your activity (or view context) has public method defined with exact same name and View as parameter. Android wires your definitions with this implementation in activity. At the end, implementation will have same code which you wrote in anonymous inner class. So, in simple words instead of having inner class and listener attachement in activity, you will simply have a public method with implementation code.

Within your component, you can define an array of number (ES6) as described below:

export class SampleComponent {
  constructor() {
    this.numbers = Array(5).fill(0).map((x,i)=>i);
  }
}

See this link for the array creation: Tersest way to create an array of integers from 1..20 in JavaScript.

You can then iterate over this array with ngFor:

@View({
  template: `
    <ul>
      <li *ngFor="let number of numbers">{{number}}</li>
    </ul>
  `
})
export class SampleComponent {
  (...)
}

Or shortly:

@View({
  template: `
    <ul>
      <li *ngFor="let number of [0,1,2,3,4]">{{number}}</li>
    </ul>
  `
})
export class SampleComponent {
  (...)
}

Hope it helps you, Thierry

Edit: Fixed the fill statement and template syntax.

It supports lists, but not as a separate data structure (ignoring arrays for the moment).

The for loop iterates over a list (in the generic sense) of white-space separated values, regardless of how that list is created, whether literally:

for i in 1 2 3; do
    echo "$i"
done

or via parameter expansion:

listVar="1 2 3"
for i in $listVar; do
    echo "$i"
done

or command substitution:

for i in $(echo 1; echo 2; echo 3); do
    echo "$i"
done

An array is just a special parameter which can contain a more structured list of value, where each element can itself contain whitespace. Compare the difference:

array=("item 1" "item 2" "item 3")
for i in "${array[@]}"; do   # The quotes are necessary here
    echo "$i"
done

list='"item 1" "item 2" "item 3"'
for i in $list; do
    echo $i
done
for i in "$list"; do
    echo $i
done
for i in ${array[@]}; do
    echo $i
done

EDIT:

Ok I found why the int.ToString() in LINQtoEF fails, please read this post: Problem with converting int to string in Linq to entities

This works on my side :

        List<string> materialTypes = (from u in result.Users
                                      select u.LastName)
                       .Union(from u in result.Users
                               select SqlFunctions.StringConvert((double) u.UserId)).ToList();

On yours it should be like this:

    IList<String> materialTypes = ((from tom in context.MaterialTypes
                                       where tom.IsActive == true
                                       select tom.Name)
                                       .Union(from tom in context.MaterialTypes
                                       where tom.IsActive == true
                                       select SqlFunctions.StringConvert((double)tom.ID))).ToList();

Thanks, i've learnt something today :)

i am very new to this website. I am an undergraduate student, doing my Bachelor Of Computer Application. I am doing a simple program in Visual Studio using C# and I came across the same problem, how to check whether a button is clicked? I wanted to do this,

if(-button1 is clicked-) then
{
this should happen;
}
if(-button2 is clicked-) then
{
this should happen;
}

I didn't know what to do, so I tried searching for the solution in the internet. I got many solutions which didn't help me. So, I tried something on my own and did this,

int i;
private void button1_Click(object sender, EventArgs e)
        {
            i = 1;
            label3.Text = "Principle";
            label4.Text = "Rate";
            label5.Text = "Time";
            label6.Text = "Simple Interest";
        }


private void button2_Click(object sender, EventArgs e)
        {
            i = 2;
            label3.Text = "SI";
            label4.Text = "Rate";
            label5.Text = "Time";
            label6.Text = "Principle";
        }
private void button5_Click(object sender, EventArgs e)
        {

            try
            {
                if (i == 1)
                {
                    si = (Convert.ToInt32(textBox1.Text) * Convert.ToInt32(textBox2.Text) * Convert.ToInt32(textBox3.Text)) / 100;
                    textBox4.Text = Convert.ToString(si);
                }
                if (i == 2)
                {
                    p = (Convert.ToInt32(textBox1.Text) * 100) / (Convert.ToInt32(textBox2.Text) * Convert.ToInt32(textBox3.Text));
                    textBox4.Text = Convert.ToString(p);
                }

I declared a variable "i" and assigned it with different values in different buttons and checked the value of i in the if function. It worked. Give your suggestions if any. Thank you.

If you have a hard time remembering the default values (I know I have...) here's a short extract from BalusC's answer:

In gitk --all:

• right click on the commit you want
• -> create new branch
• enter the name of an existing branch
• press return on the dialog that confirms replacing the old branch of that name.

Beware that re-creating instead of modifying the existing branch will lose tracking-branch information. (This is generally not a problem for simple use-cases where there's only one remote and your local branch has the same name as the corresponding branch in the remote. See comments for more details, thanks @mbdevpl for pointing out this downside.)

It would be cool if gitk had a feature where the dialog box had 3 options: overwrite, modify existing, or cancel.

Even if you're normally a command-line junkie like myself, git gui and gitk are quite nicely designed for the subset of git usage they allow. I highly recommend using them for what they're good at (i.e. selectively staging hunks into/out of the index in git gui, and also just committing. (ctrl-s to add a signed-off: line, ctrl-enter to commit.)

gitk is great for keeping track of a few branches while you sort out your changes into a nice patch series to submit upstream, or anything else where you need to keep track of what you're in the middle of with multiple branches.

I don't even have a graphical file browser open, but I love gitk/git gui.

Me did not nothing, just copied development Bin folder DLLs to online deployed Bin folder and it worked fine for me.

For what it is worth I came to this page because I had the same problem. I never got anywhere except some IMAP stuff that I don't understand. Then I remembered I had uninstalled privoxy on my ubuntu (because of some weird runtime error that mentioned 127.0.0.1:8118 when I used Daniel Kehoe's Rails template, https://github.com/RailsApps/rails3-application-templates [never discovered what it was]) and I hadn't changed my terminal to the state of no system wide proxy, under network proxy.

I know this may not be on-point but if I wound up here maybe other privoxy users can benefit too.

I don't think any built-in feature of the standard Date object will do this for you in a way that's more convenient than just doing the math yourself.

hours = Math.floor(totalSeconds / 3600);
totalSeconds %= 3600;
minutes = Math.floor(totalSeconds / 60);
seconds = totalSeconds % 60;

Example:

let totalSeconds = 28565;_x000D_
let hours = Math.floor(totalSeconds / 3600);_x000D_
totalSeconds %= 3600;_x000D_
let minutes = Math.floor(totalSeconds / 60);_x000D_
let seconds = totalSeconds % 60;_x000D_
_x000D_
console.log("hours: " + hours);_x000D_
console.log("minutes: " + minutes);_x000D_
console.log("seconds: " + seconds);_x000D_
_x000D_
// If you want strings with leading zeroes:_x000D_
minutes = String(minutes).padStart(2, "0");_x000D_
hours = String(hours).padStart(2, "0");_x000D_
seconds = String(seconds).padStart(2, "0");_x000D_
console.log(hours + ":" + minutes + ":" + seconds);

Yes, if you redirect the output, it won't appear on the console. Use tee.

and use the class in div. like here.

<div> <p class = "scrol" id = "title">-</p></div>

If you have any difficulties managing your global CLI version it is better to use NVM: MAC, Windows.

To update the local CLI in your Angular project follow this steps:

Starting from CLI v6 you can just run ng update in order to get your dependencies updated automatically to a new version.

ng update @angular/cli

With ng update sometimes you might want to add --force flag.

You can also pass --all flag to upgrade all packages at the same time.

ng update --all --force

If you want just to migrate CLI just run this:

ng update @angular/cli --migrateOnly

You can also pass flag --from=from- version from which to migrate from, e.g --from=1.7.4. This flag is only available with a single package being updated, and only on migration only.

After update is done make sure that the version of typescript you got installed supported by your current angular version, otherwise you might need to downgrade the typescript version. Also bear in mind that usually the latest version of angular won't support the latest version of the typescript.

OLD ANSWER:
All you need to do is to diff with angular-cli-diff and apply the changes in your current project.

Here is the steps:

1. Say you go from 1.4. to 1.5 then you do https://github.com/cexbrayat/angular-cli-diff/compare/1.4.0...1.5.0
2. click on File changed tab
3. Apply the changes to your current project.
4. npm install / yarn
5. Test all npm scripts (more details here: https://stackoverflow.com/a/45431592/415078)

If gives "permission denied" on adb shell -> su...

Some ROMs are running adbd daemon in secure mode (adbd has no root access and su command does not even show permission ask dialog on the device). In this case you will get "permission denied" when you try cmd -> adb shell -> su. The solution I've found is one app from the famous modder Chainfire called Adbd Insecure.

The way Facebook does this is pretty interesting.

A common method of doing such notifications is to poll a script on the server (using AJAX) on a given interval (perhaps every few seconds), to check if something has happened. However, this can be pretty network intensive, and you often make pointless requests, because nothing has happened.

The way Facebook does it is using the comet approach, rather than polling on an interval, as soon as one poll completes, it issues another one. However, each request to the script on the server has an extremely long timeout, and the server only responds to the request once something has happened. You can see this happening if you bring up Firebug's Console tab while on Facebook, with requests to a script possibly taking minutes. It is quite ingenious really, since this method cuts down immediately on both the number of requests, and how often you have to send them. You effectively now have an event framework that allows the server to 'fire' events.

Behind this, in terms of the actual content returned from those polls, it's a JSON response, with what appears to be a list of events, and info about them. It's minified though, so is a bit hard to read.

In terms of the actual technology, AJAX is the way to go here, because you can control request timeouts, and many other things. I'd recommend (Stack overflow cliche here) using jQuery to do the AJAX, it'll take a lot of the cross-compability problems away. In terms of PHP, you could simply poll an event log database table in your PHP script, and only return to the client when something happens? There are, I expect, many ways of implementing this.

Implementing:

Server Side:

There appear to be a few implementations of comet libraries in PHP, but to be honest, it really is very simple, something perhaps like the following pseudocode:

while(!has_event_happened()) {
   sleep(5);
}

echo json_encode(get_events());

• The has_event_happened function would just check if anything had happened in an events table or something, and then the get_events function would return a list of the new rows in the table? Depends on the context of the problem really.

• Don't forget to change your PHP max execution time, otherwise it will timeout early!

Client Side:

Take a look at the jQuery plugin for doing Comet interaction:

• Project homepage: http://plugins.jquery.com/project/Comet
• Google Code: https://code.google.com/archive/p/jquerycomet/ - Appears to have some sort of example usage in the subversion repository.

That said, the plugin seems to add a fair bit of complexity, it really is very simple on the client, perhaps (with jQuery) something like:

function doPoll() {
   $.get("events.php", {}, function(result) {
      $.each(result.events, function(event) { //iterate over the events
          //do something with your event
      });
      doPoll(); 
      //this effectively causes the poll to run again as
      //soon as the response comes back
   }, 'json'); 
}

$(document).ready(function() {
    $.ajaxSetup({
       timeout: 1000*60//set a global AJAX timeout of a minute
    });
    doPoll(); // do the first poll
});

The whole thing depends a lot on how your existing architecture is put together.

Just saw this old question looking to see if Windows had something built in. The ~z thing is something I didn't know about, but not applicable for me. I ended up with a Perl one-liner:

@echo off

set yourfile=output.txt
set maxsize=10000

perl -e "-s $ENV{yourfile} > $ENV{maxsize} ? exit 1 : exit 0"
rem if %errorlevel%. equ 1. goto abort
if errorlevel 1 goto abort

echo OK!
exit /b 0

:abort
echo Bad!
exit /b 1

The easiest way:

python 2

import urllib2, ssl

request = urllib2.Request('https://somedomain.co/')
response = urllib2.urlopen(request, context=ssl._create_unverified_context())

python 3

from urllib.request import urlopen
import ssl

response = urlopen('https://somedomain.co', context=ssl._create_unverified_context())

By putting an assignment of list on a variable first

myVar <- list()

it opens the possibility of hiearchial assignments by

myVar[[1]] <- list()
myVar[[2]] <- list()

and so on... so now it's possible to do

myVar[[1]][[1]] <- c(...)
myVar[[1]][[2]] <- c(...)

or

myVar[[1]][['subVar']] <- c(...)

and so on

it is also possible to assign directly names (instead of $)

myVar[['nameofsubvar]] <- list()

and then

myVar[['nameofsubvar]][['nameofsubsubvar']] <- c('...')

important to remember is to always use double brackets to make the system work

then to get information is simple

myVar$nameofsubvar$nameofsubsubvar

and so on...

example:

a <-list()
a[['test']] <-list()
a[['test']][['subtest']] <- c(1,2,3)
a
$test
$test$subtest
[1] 1 2 3


a[['test']][['sub2test']] <- c(3,4,5)
a
$test
$test$subtest
[1] 1 2 3

$test$sub2test
[1] 3 4 5

a nice feature of the R language in it's hiearchial definition...

I used it for a complex implementation (with more than two levels) and it works!

You might be needing a cleanup:

git gc --prune=now

or you might be needing a prune:

git remote prune public

prune

Deletes all stale tracking branches under <name>. These stale branches have already been removed from the remote repository referenced by <name>, but are still locally available in "remotes/<name>".

With --dry-run option, report what branches will be pruned, but do no actually prune them.

However, it appears these should have been cleaned up earlier with

git remote rm public 

rm

Remove the remote named <name>. All remote tracking branches and configuration settings for the remote are removed.

So it might be you hand-edited your config file and this did not occur, or you have privilege problems.

Maybe run that again and see what happens.

Advice Context

If you take a look in the revision logs, you'll note I suggested more "correct" techniques, which for whatever reason didn't want to work on their repository.

I suspected the OP had done something that left their tree in an inconsistent state that caused it to behave a bit strangely, and git gc was required to fix up the left behind cruft.

Usually git branch -rd origin/badbranch is sufficient for nuking a local tracking branch , or git push origin :badbranch for nuking a remote branch, and usually you will never need to call git gc

Try this

SELECT CAST(DataField AS time(7)) AS 'time'

Assuming you want to use numpy, you can numerically compute the derivative of a function at any point using the Rigorous definition:

def d_fun(x):
    h = 1e-5 #in theory h is an infinitesimal
    return (fun(x+h)-fun(x))/h

You can also use the Symmetric derivative for better results:

def d_fun(x):
    h = 1e-5
    return (fun(x+h)-fun(x-h))/(2*h)

Using your example, the full code should look something like:

def fun(x):
    return x**2 + 1

def d_fun(x):
    h = 1e-5
    return (fun(x+h)-fun(x-h))/(2*h)

Now, you can numerically find the derivative at x=5:

In [1]: d_fun(5)
Out[1]: 9.999999999621423

This is what worked for me.

set hive.resultset.use.unique.column.names=false;

A void* does not mean anything. It is a pointer, but the type that it points to is not known.

It's not that it can return "anything". A function that returns a void* generally is doing one of the following:

• It is dealing in unformatted memory. This is what operator new and malloc return: a pointer to a block of memory of a certain size. Since the memory does not have a type (because it does not have a properly constructed object in it yet), it is typeless. IE: void.
• It is an opaque handle; it references a created object without naming a specific type. Code that does this is generally poorly formed, since this is better done by forward declaring a struct/class and simply not providing a public definition for it. Because then, at least it has a real type.
• It returns a pointer to storage that contains an object of a known type. However, that API is used to deal with objects of a wide variety of types, so the exact type that a particular call returns cannot be known at compile time. Therefore, there will be some documentation explaining when it stores which kinds of objects, and therefore which type you can safely cast it to.

This construct is nothing like dynamic or object in C#. Those tools actually know what the original type is; void* does not. This makes it far more dangerous than any of those, because it is very easy to get it wrong, and there's no way to ask if a particular usage is the right one.

And on a personal note, if you see code that uses void*'s "often", you should rethink what code you're looking at. void* usage, especially in C++, should be rare, used primary for dealing in raw memory.

1. remove git data, rm .git
2. git init
3. add a git remote
4. force push

Generally, you can use the func(*tuple) syntax. You can even pass a part of the tuple, which seems like what you're trying to do here:

t = (2010, 10, 2, 11, 4, 0, 2, 41, 0)
dt = datetime.datetime(*t[0:7])

This is called unpacking a tuple, and can be used for other iterables (such as lists) too. Here's another example (from the Python tutorial):

>>> range(3, 6)             # normal call with separate arguments
[3, 4, 5]
>>> args = [3, 6]
>>> range(*args)            # call with arguments unpacked from a list
[3, 4, 5]

This worked for me :

select option {
   color: black;
}
select:not(:checked) {
   color: gray;
}

Another way to handle this that removes any need for includes at all is to use the autoload feature. Including everything your script needs "Just in Case" can impede performance. If your includes are all class or interface definitions, and you want to load them only when needed, you can overload the __autoload() function with your own code to find the appropriate class file and load it only when it's called. Here is the example from the manual:

function __autoload($class_name) {
    require_once $class_name . '.php';
}

$obj  = new MyClass1();
$obj2 = new MyClass2(); 

As long as you set your include_path variables accordingly, you never need to include a class file again.

You should convert first DataSource in BindingSource, look example

BindingSource bs = (BindingSource)dgrid.DataSource; // Se convierte el DataSource 
DataTable tCxC = (DataTable) bs.DataSource;

With the data of tCxC you can do anything.

This will work:

#div{
     max-height:300px;
     overflow:hidden;
}
#div:hover{
     overflow-y:scroll;
}

Swift 3:

let documentsURL = try! FileManager().url(for: .documentDirectory,
                                          in: .userDomainMask,
                                          appropriateFor: nil,
                                          create: true)

... gives you a file URL of the documents directory. The following checks if there's a file named foo.html:

let fooURL = documentsURL.appendingPathComponent("foo.html")
let fileExists = FileManager().fileExists(atPath: fooURL.path)

Objective-C:

NSString* documentsPath = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES)[0];

NSString* foofile = [documentsPath stringByAppendingPathComponent:@"foo.html"];
BOOL fileExists = [[NSFileManager defaultManager] fileExistsAtPath:foofile];

this is more likely happening because somewhere along your certificate chain you have a certificate, more likely an old root, which is still signed with the MD2RSA algorythm.

You need to locate it into your certificate store and delete it.

Then get back to your certification authority and ask them for then new root.

It will more likely be the same root with the same validity period but it has been recertified with SHA1RSA.

Hope this help.

There is no difference.

COUNT(1) is basically just counting a constant value 1 column for each row. As other users here have said, it's the same as COUNT(0) or COUNT(42). Any non-NULL value will suffice.

http://asktom.oracle.com/pls/asktom/f?p=100:11:2603224624843292::::P11_QUESTION_ID:1156151916789

The Oracle optimizer did apparently use to have bugs in it, which caused the count to be affected by which column you picked and whether it was in an index, so the COUNT(1) convention came into being.

Good news everyone, there's an isBetween function! Update your library ;)

Simple, standard library only. Gives timezone-aware datetime, unlike datetime.utcnow().

from datetime import datetime,timezone
now_utc = datetime.now(timezone.utc)

An Alternative Solution to the above

Card(
  shape: RoundedRectangleBorder(
     borderRadius: BorderRadius.only(topLeft: Radius.circular(20), topRight: Radius.circular(20))),
  color: Colors.white,
  child: ...
)

You can use BorderRadius.only() to customize the corners you wish to manage.

Just to add description for another one case. I've got to install similar Vagrant Ubuntu 18.04 based configurations to multiple Ubuntu machines. Downloaded bionic64 box to one using vagrant up with Vagrantfile where this box was specified, then copied folder .vagrant.d/boxes/ubuntu-VAGRANTSLASH-bionic64 to others.

As claustrofob said, oninput is supported for IE9+.

However, "The oninput event is buggy in Internet Explorer 9. It is not fired when characters are deleted from a text field through the user interface only when characters are inserted. Although the onpropertychange event is supported in Internet Explorer 9, but similarly to the oninput event, it is also buggy, it is not fired on deletion.

Since characters can be deleted in several ways (Backspace and Delete keys, CTRL + X, Cut and Delete command in context menu), there is no good solution to detect all changes. If characters are deleted by the Delete command of the context menu, the modification cannot be detected in JavaScript in Internet Explorer 9."

I have good results binding to both input and keyup (and keydown, if you want it to fire in IE while holding down the Backspace key).

The answer of ADTC works fine, but I've find another solution, so I post it here if someone wants something different.

I think ADTC's solution is better, but mine's also works.

Here is the other solution I found

select p.name
from   person p
where  instr(p.name,chr(8211)) > 0; --contains the character chr(8211) 
                                    --at least 1 time

Thank you.

In the code below, Class A implements the interface IShow and implements its method ShowData. Class B inherits Class A. In order to use ShowData method in Class B, we have to use keyword new in the ShowData method in order to hide the base class Class A method and use override keyword in order to extend the method.

interface IShow
{
    protected void ShowData();
}

class A : IShow
{
    protected void ShowData()
    {
        Console.WriteLine("This is Class A");
    }
}

class B : A
{
    protected new void ShowData()
    {
        Console.WriteLine("This is Class B");
    }
}

Note: I see that someone (not @unutbu) changed the referenced answer so that it no longer uses vars()['Foo'] — so the primary point of my post no longer applies.

FWIW, here's what I meant about @unutbu's answer only working with locally defined classes — and that using eval() instead of vars() would make it work with any accessible class, not only those defined in the current scope.

For those who dislike using eval(), a way is also shown to avoid it.

First here's a concrete example demonstrating the potential problem with using vars():

class Foo(object): pass
class Bar(Foo): pass
class Baz(Foo): pass
class Bing(Bar): pass

# unutbu's approach
def all_subclasses(cls):
    return cls.__subclasses__() + [g for s in cls.__subclasses__()
                                       for g in all_subclasses(s)]

print(all_subclasses(vars()['Foo']))  # Fine because  Foo is in scope
# -> [<class '__main__.Bar'>, <class '__main__.Baz'>, <class '__main__.Bing'>]

def func():  # won't work because Foo class is not locally defined
    print(all_subclasses(vars()['Foo']))

try:
    func()  # not OK because Foo is not local to func()
except Exception as e:
    print('calling func() raised exception: {!r}'.format(e))
    # -> calling func() raised exception: KeyError('Foo',)

print(all_subclasses(eval('Foo')))  # OK
# -> [<class '__main__.Bar'>, <class '__main__.Baz'>, <class '__main__.Bing'>]

# using eval('xxx') instead of vars()['xxx']
def func2():
    print(all_subclasses(eval('Foo')))

func2()  # Works
# -> [<class '__main__.Bar'>, <class '__main__.Baz'>, <class '__main__.Bing'>]

This could be improved by moving the eval('ClassName') down into the function defined, which makes using it easier without loss of the additional generality gained by using eval() which unlike vars() is not context-sensitive:

# easier to use version
def all_subclasses2(classname):
    direct_subclasses = eval(classname).__subclasses__()
    return direct_subclasses + [g for s in direct_subclasses
                                    for g in all_subclasses2(s.__name__)]

# pass 'xxx' instead of eval('xxx')
def func_ez():
    print(all_subclasses2('Foo'))  # simpler

func_ez()
# -> [<class '__main__.Bar'>, <class '__main__.Baz'>, <class '__main__.Bing'>]

Lastly, it's possible, and perhaps even important in some cases, to avoid using eval() for security reasons, so here's a version without it:

def get_all_subclasses(cls):
    """ Generator of all a class's subclasses. """
    try:
        for subclass in cls.__subclasses__():
            yield subclass
            for subclass in get_all_subclasses(subclass):
                yield subclass
    except TypeError:
        return

def all_subclasses3(classname):
    for cls in get_all_subclasses(object):  # object is base of all new-style classes.
        if cls.__name__.split('.')[-1] == classname:
            break
    else:
        raise ValueError('class %s not found' % classname)
    direct_subclasses = cls.__subclasses__()
    return direct_subclasses + [g for s in direct_subclasses
                                    for g in all_subclasses3(s.__name__)]

# no eval('xxx')
def func3():
    print(all_subclasses3('Foo'))

func3()  # Also works
# -> [<class '__main__.Bar'>, <class '__main__.Baz'>, <class '__main__.Bing'>]

except Exception:
    pass

This will only give you marginal protection. If the attacker can run arbitrary code in your application they can get at the passwords in exactly the same way your application can. You could still get some protection from some SQL injection attacks and misplaced db backups if you store a secret key in a file and use that to encrypt on the way to the db and decrypt on the way out. But you should use bindparams to completely avoid the issue of SQL injection.

If decide to encrypt, you should use some high level crypto library for this, or you will get it wrong. You'll have to get the key-setup, message padding and integrity checks correct, or all your encryption effort is of little use. GPGME is a good choice for one example. Mcrypt is too low level and you will probably get it wrong.

• npm install installs the depedendencies in your package.json config.
• npm run build runs the script "build" and created a script which runs your application - let's say server.js
• npm start runs the "start" script which will then be "node server.js"

It's difficult to tell exactly what the issue was but basically if you look at your scripts configuration, I would guess that "build" uses some kind of build tool to create your application while "start" assumes the build has been done but then fails if the file is not there.

You are probably using bower or grunt - I seem to remember that a typical grunt application will have defined those scripts as well as a "clean" script to delete the last build.

Build tools tend to create a file in a bin/, dist/, or build/ folder which the start script then calls - e.g. "node build/server.js". When your npm start fails, it is probably because you called npm clean or similar to delete the latest build so your application file is not present causing npm start to fail.

npm build's source code - to touch on the discussion in this question - is in github for you to have a look at if you like. If you run npm build directly and you have a "build" script defined, it will exit with an error asking you to call your build script as npm run-script build so it's not the same as npm run script.

I'm not quite sure what npm build does, but it seems to be related to postinstall and packaging scripts in dependencies. I assume that this might be making sure that any CLI build scripts's or native libraries required by dependencies are built for the specific environment after downloading the package. This will be why link and install call this script.

You would still need to go through the DataTable class. But you can do so using your DataRow instance by using the Table property.

foreach (DataColumn c in dr.Table.Columns)  //loop through the columns. 
{
    MessageBox.Show(c.ColumnName);
}

Stephen Darlington makes a very good point, and you can see that if you change my benchmark to use a more realistically sized table if I fill the table out to 10000 rows using the following:

begin 
  for i in 2 .. 10000 loop
    insert into t (NEEDED_FIELD, cond) values (i, 10);
  end loop;
end;

Then re-run the benchmarks. (I had to reduce the loop counts to 5000 to get reasonable times).

declare
  otherVar  number;
  cnt number;
begin
  for i in 1 .. 5000 loop
     select count(*) into cnt from t where cond = 0;

     if (cnt = 1) then
       select NEEDED_FIELD INTO otherVar from t where cond = 0;
     else
       otherVar := 0;
     end if;
   end loop;
end;
/

declare
  otherVar  number;
begin
  for i in 1 .. 5000 loop
     begin

       when no_data_found then
         otherVar := 0;
     end;
   end loop;
end;

The method with the exception is now more than twice as fast. So, for almost all cases,the method:

SELECT NEEDED_FIELD INTO var WHERE condition;
EXCEPTION
WHEN NO_DATA_FOUND....

is the way to go. It will give correct results and is generally the fastest.

How about with a :before pseudoelement:

a:before {
  content: '\a';
  white-space: pre;
}

Add a margin to your li tags. That will create space between the li and you can use line-height to set the spacing to the text within the li tags.

I would say there is also a starred notation for the import ES6 keyword worth to mention.

If you try to console log Mix:

import * as Mix from "./A";
console.log(Mix);

You will get:

When should I use curly braces for ES6 import?

The brackets are golden when you need only specific components from the module, which makes smaller footprints for bundlers like webpack.

Check for the 32/64 bit you trying to install. both python interpreter and your app which trying to use python might be of different bit.

All depends on your visualization of the array. Rows and Columns are properties of visualization (probably in your imagination) of the array, not the array itself.

It's exactly the same as asking is number "5" red or green?

I could draw it red, I could draw it greed right? Color is not an integral property of a number. In the same way representing 2D array as a grid of rows and columns is not necessary for existence of this array.

2D array has just first dimention and second dimention, everything related to visualizing those is purely your flavour.

When I have char array char[80][25], I may like to print it on console rotated so that I have 25 rows of 80 characters that fits the screen without scroll.

I'll try to provide viable example when representing 2D array as rows and columns doesn't make sense at all: Let's say I need an array of 1 000 000 000 integers. My machine has 8GB of RAM, so I have enough memory for this, but if you try executing var a = new int[1000000000], you'll most likely get OutOfMemory exception. That's because of memory fragmentation - there is no consecutive block of memory of this size. Instead you you can create 2D array 10 000 x 100 000 with your values. Logically it is 1D array, so you'd like to draw and imagine it as a single sequence of values, but due to technical implementation it is 2D.

Simply we can trace the request message as.

OperationContext context = OperationContext.Current;

if (context != null && context.RequestContext != null)

{

Message msg = context.RequestContext.RequestMessage;

string reqXML = msg.ToString();

OK, Firefox 7 implemented text-overflow: ellipsis as well as text-overflow: "string". Final release is planned for 2011-09-27.

For approximating short distances between two coordinates I used formulas from http://en.wikipedia.org/wiki/Lat-lon:

m_per_deg_lat = 111132.954 - 559.822 * cos( 2 * latMid ) + 1.175 * cos( 4 * latMid);
m_per_deg_lon = 111132.954 * cos ( latMid );

.

In the code below I've left the raw numbers to show their relation to the formula from wikipedia.

double latMid, m_per_deg_lat, m_per_deg_lon, deltaLat, deltaLon,dist_m;

latMid = (Lat1+Lat2 )/2.0;  // or just use Lat1 for slightly less accurate estimate


m_per_deg_lat = 111132.954 - 559.822 * cos( 2.0 * latMid ) + 1.175 * cos( 4.0 * latMid);
m_per_deg_lon = (3.14159265359/180 ) * 6367449 * cos ( latMid );

deltaLat = fabs(Lat1 - Lat2);
deltaLon = fabs(Lon1 - Lon2);

dist_m = sqrt (  pow( deltaLat * m_per_deg_lat,2) + pow( deltaLon * m_per_deg_lon , 2) );

The wikipedia entry states that the distance calcs are within 0.6m for 100km longitudinally and 1cm for 100km latitudinally but I have not verified this as anywhere near that accuracy is fine for my use.

I had two interfaces. First was child of other. I did following:

1. Added index signature in parent interface.
2. Used appropriate type using as keyword.

Complete code is as below:

Child Interface:

interface UVAmount {
  amount: number;
  price: number;
  quantity: number;
};

Parent Interface:

interface UVItem  {
// This is index signature which compiler is complaining about.
// Here we are mentioning key will string and value will any of the types mentioned.
  [key: string]:  UVAmount | string | number | object;

  name: string;
  initial: UVAmount;
  rating: number;
  others: object;
};

React Component:

let valueType = 'initial';

function getTotal(item: UVItem) {
// as keyword is the dealbreaker.
// If you don't use it, it will take string type by default and show errors.
  let itemValue = item[valueType] as UVAmount;

  return itemValue.price * itemValue.quantity;
}

SELECT *
FROM TableName
WHERE julianday(substr(date,7)||'-'||substr(date,4,2)||'-'||substr(date,1,2)) BETWEEN julianday('2011-01-11') AND julianday('2011-08-11')

Note that I use the format : dd/mm/yyyy

If you use d/m/yyyy, Change in substr()

Hope this will help you.

What about:

PrintWriter out = response.getWriter();
out.println("THE_STRING_TO_SEND_AS_RESPONSE");

This woks for me.

A covered query is a query where all the columns in the query's result set are pulled from non-clustered indexes.

A query is made into a covered query by the judicious arrangement of indexes.

A covered query is often more performant than a non-covered query in part because non-clustered indexes have more rows per page than clustered indexes or heap indexes, so fewer pages need to be brought into memory in order to satisfy the query. They have more rows per page because only part of the table row is part of the index row.

A covering index is an index which is used in a covered query. There is no such thing as an index which, in and of itself, is a covering index. An index may be a covering index with respect to query A, while at the same time not being a covering index with respect to query B.

If you've been using the OnDestry lifecycle hook, you might be interested in using something like this before calling window.location.href=...

    this.router.ngOnDestroy();
    window.location.href = 'http://www.cnn.com/';

that will trigger the OnDestry callback in your component that you might like.

Ohh, and also:

import { Router } from '@angular/router';

is where you find the router.

---EDIT--- Sadly, I might have been wrong in the example above. At least it's not working as exepected in my production code right now - so, until I have time to investigate further, I solve it like this (since my app really need the hook when possible)

this.router.navigate(["/"]).then(result=>{window.location.href = 'http://www.cnn.com/';});

Basically routing to any (dummy) route to force the hook, and then navigate as requested.

You can use OLDand NEW in the trigger to access those values which had changed in that trigger. Mysql Ref

Thanks Hong, that was exactly the problem I was running into. The error you get suggests that the number of rows is wrong, but the problem is actually that the model has been trained using a command that ends up with the wrong names for parameters.

This is really a critical detail that is entirely non-obvious for lm and so on. Some of the tutorial make reference to doing lines like lm(olive$Area@olive$Palmitic) - ending up with variable names of olive$Area NOT Area, so creating an entry using anewdata<-data.frame(Palmitic=2) can't then be used. If you use lm(Area@Palmitic,data=olive) then the variable names are right and prediction works.

The real problem is that the error message does not indicate the problem at all:

Warning message: 'anewdata' had 1 rows but variable(s) found to have X rows

You cannot access a local directory from pl/sql. If you use bfile, you will setup a directory (create directory) on the server where Oracle is running where you will need to put your images.

If you want to insert a handful of images from your local machine, you'll need a client side app to do this. You can write your own, but I typically use Toad for this. In schema browser, click onto the table. Click the data tab, and hit + sign to add a row. Double click the BLOB column, and a wizard opens. The far left icon will load an image into the blob:

SQL Developer has a similar feature. See the "Load" link below:

If you need to pull images over the wire, you can do it using pl/sql, but its not straight forward. First, you'll need to setup ACL list access (for security reasons) to allow a user to pull over the wire. See this article for more on ACL setup.

Assuming ACL is complete, you'd pull the image like this:

declare
    l_url varchar2(4000) := 'http://www.oracleimg.com/us/assets/12_c_navbnr.jpg';
    l_http_request   UTL_HTTP.req;
    l_http_response  UTL_HTTP.resp;
    l_raw RAW(2000);
    l_blob BLOB;
begin
   -- Important: setup ACL access list first!

    DBMS_LOB.createtemporary(l_blob, FALSE);

    l_http_request  := UTL_HTTP.begin_request(l_url);
    l_http_response := UTL_HTTP.get_response(l_http_request);

  -- Copy the response into the BLOB.
  BEGIN
    LOOP
      UTL_HTTP.read_raw(l_http_response, l_raw, 2000);
      DBMS_LOB.writeappend (l_blob, UTL_RAW.length(l_raw), l_raw);
    END LOOP;
  EXCEPTION
    WHEN UTL_HTTP.end_of_body THEN
      UTL_HTTP.end_response(l_http_response);
  END;

  insert into my_pics (pic_id, pic) values (102, l_blob);
  commit;

  DBMS_LOB.freetemporary(l_blob); 
end;

Hope that helps.

When i analyzed your code. I have also faced the same problem but my problem is if i give value for both first and last name means it is working fine. but when i give only one value means it says 400. anyway use the .andDo(print()) method to find out the error

public void testGetUserByName() throws Exception {
    String firstName = "Jack";
    String lastName = "s";       
    this.userClientObject = client.createClient();
    mockMvc.perform(get("/byName")
            .sessionAttr("userClientObject", this.userClientObject)
            .param("firstName", firstName)
            .param("lastName", lastName)               
    ).andDo(print())
     .andExpect(status().isOk())
            .andExpect(content().contentType("application/json"))
            .andExpect(jsonPath("$[0].id").exists())
            .andExpect(jsonPath("$[0].fn").value("Marge"));
}

If your problem is org.springframework.web.bind.missingservletrequestparameterexception you have to change your code to

@RequestMapping(value = "/byName", method = RequestMethod.GET)
    @ResponseStatus(HttpStatus.OK)
    public
    @ResponseBody
    String getUserByName(
        @RequestParam( value="firstName",required = false) String firstName,
        @RequestParam(value="lastName",required = false) String lastName, 
        @ModelAttribute("userClientObject") UserClient userClient)
    {

        return client.getUserByName(userClient, firstName, lastName);
    }

int is inherently finite; there's no value that satisfies your requirements.

If you're willing to change the type of b, though, you can do this with operator overrides:

class infinitytype {};

template<typename T>
bool operator>(const T &, const infinitytype &) {
  return false;
}

template<typename T>
bool operator<(const T &, const infinitytype &) {
  return true;
}

bool operator<(const infinitytype &, const infinitytype &) {
  return false;
}


bool operator>(const infinitytype &, const infinitytype &) {
  return false;
}

// add operator==, operator!=, operator>=, operator<=...

int main() {
  std::cout << ( INT_MAX < infinitytype() ); // true
}

Try this code its working perfect

<script>
$(function() {

    $("#submit").hide();

    $("#page-changer select").change(function() {
        window.location = $("#page-changer select option:selected").val();
    })

});
</script>

<?php
    if (isset($_POST['nav'])) {
         header("Location: $_POST[nav]");
    }
?>
<form id="page-changer" action="" method="post">
    <select name="nav">
        <option value="">Go to page...</option>
        <option value="http://css-tricks.com/">CSS-Tricks</option>
        <option value="http://digwp.com/">Digging Into WordPress</option>
        <option value="http://quotesondesign.com/">Quotes on Design</option>
    </select>
    <input type="submit" value="Go" id="submit" />
</form>

UPDATE:

All of the above answers won't work for the repeated values, @BenBolker's answer using duplicated() predicate solves this:

full_vector[!full_vector %in% searched_vector | duplicated(full_vector)]

Original Answer: here I write a little function for this:

exclude_val<-function(full_vector,searched_vector){

      found=c()

      for(i in full_vector){  

        if(any(is.element(searched_vector,i))){
          searched_vector[(which(searched_vector==i))[1]]=NA
        }
        else{
          found=c(found,i)
        }
    }

    return(found)
}

so, let's say full_vector=c(1,2,3,4,1) and searched_vector=c(1,2,3).

exclude_val(full_vector,searched_vector) will return (4,1), however above answers will return just (4).

You need to use RegularExpression Attribute, something like this:

[RegularExpression("^[a-zA-Z0-9_\\.-]+@([a-zA-Z0-9-]+\\.)+[a-zA-Z]{2,6}$", ErrorMessage = "E-mail is not valid")]

And don't delete [Required] because [RegularExpression] doesn't affect empty fields.

I got the same error in a project I was working with in VB.NET. Checking the "Enable application framework" on the properties page solved it for me.

In your Controller

public function updtitle() 
{   
    $data = array(
        'table_name' => 'your_table_name_to_update', // pass the real table name
        'id' => $this->input->post('id'),
        'title' => $this->input->post('title')
    );

    $this->load->model('Updmodel'); // load the model first
    if($this->Updmodel->upddata($data)) // call the method from the model
    {
        // update successful
    }
    else
    {
        // update not successful
    }

}

In Your Model

public function upddata($data) {
    extract($data);
    $this->db->where('emp_no', $id);
    $this->db->update($table_name, array('title' => $title));
    return true;
}

The active record query is similar to

"update $table_name set title='$title' where emp_no=$id"

Thanks for all answers above, but for me, I can not find Base64Encoder class, so I sort out my way anyway.

public static void main(String[] args) {
    try {
        DefaultHttpClient Client = new DefaultHttpClient();

        HttpGet httpGet = new HttpGet("https://httpbin.org/basic-auth/user/passwd");
        String encoding = DatatypeConverter.printBase64Binary("user:passwd".getBytes("UTF-8"));
        httpGet.setHeader("Authorization", "Basic " + encoding);

        HttpResponse response = Client.execute(httpGet);

        System.out.println("response = " + response);

        BufferedReader breader = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));
        StringBuilder responseString = new StringBuilder();
        String line = "";
        while ((line = breader.readLine()) != null) {
            responseString.append(line);
        }
        breader.close();
        String repsonseStr = responseString.toString();

        System.out.println("repsonseStr = " + repsonseStr);

    } catch (IOException e) {
        e.printStackTrace();
    }

}

One more thing, I also tried

Base64.encodeBase64String("user:passwd".getBytes());

It does NOT work due to it return a string almost same with

DatatypeConverter.printBase64Binary()

but end with "\r\n", then server will return "bad request".

Also following code is working as well, actually I sort out this first, but for some reason, it does NOT work in some cloud environment (sae.sina.com.cn if you want to know, it is a chinese cloud service). so have to use the http header instead of HttpClient credentials.

public static void main(String[] args) {
    try {
        DefaultHttpClient Client = new DefaultHttpClient();
        Client.getCredentialsProvider().setCredentials(
                AuthScope.ANY,
                new UsernamePasswordCredentials("user", "passwd")
        );

        HttpGet httpGet = new HttpGet("https://httpbin.org/basic-auth/user/passwd");
        HttpResponse response = Client.execute(httpGet);

        System.out.println("response = " + response);

        BufferedReader breader = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));
        StringBuilder responseString = new StringBuilder();
        String line = "";
        while ((line = breader.readLine()) != null) {
            responseString.append(line);
        }
        breader.close();
        String responseStr = responseString.toString();
        System.out.println("responseStr = " + responseStr);

    } catch (IOException e) {
        e.printStackTrace();
    }
}

Looper.myLooper() == Looper.getMainLooper()

if this returns true, then you're on the UI thread!

For a Windows console app, you want to use SetConsoleCtrlHandler to handle CTRL+C and CTRL+BREAK.

See here for an example.

Use the function Contains from the strings package.

import (
    "strings"
)
strings.Contains("something", "some") // true

You can't do this directly - UITextField has no maxLength attribute, but you can set the UITextField's delegate, then use:

- (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string

CSS3: http://webdesign.about.com/od/styleproperties/p/blspbgsize.htm

.style1 {
  ...
  background-size: 100%;
}

You can specify just width or height with:

background-size: 100% 50%;

Which will stretch it 100% of the width and 50% of the height.

Browser support: http://caniuse.com/#feat=background-img-opts

If you have Python installed, you can do

python -c "import datetime;print(datetime.date.today().strftime('%Y-%m-%d'))"

You can easily adapt the format string to your needs.

This command with --user 0 do the job:

adb uninstall --user 0 <package_name>

What happens if the fragment that you want to remove is not on top of the stack?

Then you can use theses functions

popBackStack(int arg0, int arg1);

popBackStack(String arg0, int arg1);

please add these codes to your dependencies. It will work.

implementation 'org.jbundle.util.osgi.wrapped:org.jbundle.util.osgi.wrapped.org.apache.http.client:4.1.2'

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    implementation 'com.android.support:appcompat-v7:23.1.0'
    implementation 'com.android.support:design:23.1.0'
    implementation 'com.android.support:cardview-v7:23.1.0'
    implementation 'com.android.support:recyclerview-v7:23.1.0'

    implementation 'org.jbundle.util.osgi.wrapped:org.jbundle.util.osgi.wrapped.org.apache.http.client:4.1.2'
}

var str = "Hello, playground"
let indexcut = str.firstIndex(of: ",")
print(String(str[..<indexcut!]))
print(String(str[indexcut!...]))

You can try in this way and will get proper results.

Python lists are mutable objects and here:

plot_data = [[]] * len(positions) 

you are repeating the same list len(positions) times.

>>> plot_data = [[]] * 3
>>> plot_data
[[], [], []]
>>> plot_data[0].append(1)
>>> plot_data
[[1], [1], [1]]
>>> 

Each list in your list is a reference to the same object. You modify one, you see the modification in all of them.

If you want different lists, you can do this way:

plot_data = [[] for _ in positions]

for example:

>>> pd = [[] for _ in range(3)]
>>> pd
[[], [], []]
>>> pd[0].append(1)
>>> pd
[[1], [], []]

Although os.rename() and shutil.move() will both rename files, the command that is closest to the Unix mv command is shutil.move(). The difference is that os.rename() doesn't work if the source and destination are on different disks, while shutil.move() doesn't care what disk the files are on.

Use a UI library, like jquery or yui, that provides an alternative to the native SELECT element, typically as part of the implementation of a combo box.

This works as well:

In my case, same as in this question, it happened becayse I had my project in a symbolic link directory. After reopening the project in the real directory and reconfiguring gradle (File -> Sync with Gradle files) the problem went away. Shame on you, Android Studio!

Look at the "Sprite Text" sample in the GLSurfaceView samples.

This solution is for Litespeed Server (Apache as well)

Add the following code in .htaccess

RewriteRule .* - [E=noabort:1]
RewriteRule .* - [E=noconntimeout:1]

Without seeing specific code, it's difficult to give you a precise answer. However, from the Bootstrap docs, you can hide the modal like this:

$('#myModal').modal('hide')

Then, show another modal once it's hidden:

$('#myModal').on('hidden.bs.modal', function () {
  // Load up a new modal...
  $('#myModalNew').modal('show')
})

You're going to have to find a way to push the URL to the new modal window, but I'd assume that'd be trivial. Without seeing the code it's hard to give an example of that.

My answer is inspired from Andras Balázs Lajtha answer it allow to work without xml file

Adding to the mentions of jwplayer and possible TOS violations, I would like to to link to the following repository on github: YouTube Audio Player Generation Library, that allows to generate the following output:

Library has the support for the playlists and PHP autorendering given the video URL and the configuration options.

This works for me:

curl -I http://websitename.com

Which shows results like this or similar including the PHP version:

A more generic solution for might be the following.

    extendDf <- function (df, n) {
    withFactors <- sum(sapply (df, function(X) (is.factor(X)) )) > 0
    nr          <- nrow (df)
    colNames    <- names(df)
    for (c in 1:length(colNames)) {
        if (is.factor(df[,c])) {
            col         <- vector (mode='character', length = nr+n) 
            col[1:nr]   <- as.character(df[,c])
            col[(nr+1):(n+nr)]<- rep(col[1], n)  # to avoid extra levels
            col         <- as.factor(col)
        } else {
            col         <- vector (mode=mode(df[1,c]), length = nr+n)
            class(col)  <- class (df[1,c])
            col[1:nr]   <- df[,c] 
        }
        if (c==1) {
            newDf       <- data.frame (col ,stringsAsFactors=withFactors)
        } else {
            newDf[,c]   <- col 
        }
    }
    names(newDf) <- colNames
    newDf
}

The function extendDf() extends a data frame with n rows.

As an example:

aDf <- data.frame (l=TRUE, i=1L, n=1, c='a', t=Sys.time(), stringsAsFactors = TRUE)
extendDf (aDf, 2)
#      l i n c                   t
# 1  TRUE 1 1 a 2016-07-06 17:12:30
# 2 FALSE 0 0 a 1970-01-01 01:00:00
# 3 FALSE 0 0 a 1970-01-01 01:00:00

system.time (eDf <- extendDf (aDf, 100000))
#    user  system elapsed 
#   0.009   0.002   0.010
system.time (eDf <- extendDf (eDf, 100000))
#    user  system elapsed 
#   0.068   0.002   0.070

When using the new ruby, the image folder will go to asset folder on folder app

after placing your images in image folder, use

<%=image_tag("example_image.png", alt: "Example Image")%>

Try to get using:

var count = $("ul > li").size();
alert(count);

In case all your source and replacement strings are just one character long, you can simply use the TRANSLATE function:

  SELECT translate('THIS IS UPPERCASE', 'THISUP', 'thisup') 
  FROM DUAL

If you just need the name of the current directory, you could do something like this:

If I didn'n anotate the @SuppressWarnings("unchecked") here, it would have a problem with line, where I want to return my ResultList.

If you can live with 3. and 3.0 appearing as "3.0", a very simple approach that right-strips zeros from float representations:

You shouldn't edit it, you should completely scrap it.

Any attempt to make execution stop for a certain amount of time will lock up the browser and switch it to a Not Responding state. The only thing you can do is use setTimeout correctly.

The issue here is your version of AngularJS; ng-attr is not working due to the fact that it was introduced in version 1.1.4. I am unsure as to why title="{{product.shortDesc}}" isn't working for you, but I imagine it is for similar reasons (old Angular version). I tested this on 1.2.9 and it is working for me.

As for the other answers here, this is NOT among the few use cases for ng-attr! This is a simple double-curly-bracket situation:

<a title="{{product.shortDesc}}" ng-bind="product.shortDesc" />

I found that when I create Sqlconnection = new SqlConnection(), I forgot to pass my connectionString variable. So that is why I changed the way I initialize my connectionString (and nothing changed).

And if you like me just don't forget to pass your string connection into SqlConnection parameters.

Sqlconnection = new SqlConnection("ConnString")

To delete folder having files, no need of loops or recursive search. You can directly use:

FileUtils.deleteDirectory(<File object of directory>);

This function will directory delete the folder and all files in it.

Very easy, trial and error. Go to the cell you want the month in. Type the Month, go to the next cell and type the year, something weird will come up but then go to your number section click on the little arrow in the right bottom and highlight text and it will change to the year you originally typed

This worked for me, in my case I had a button with a data-id attribute:

$("a").data("item-id");

Fiddle

What you're looking for is componentWillMount.

From the documentation:

Invoked once, both on the client and server, immediately before the initial rendering occurs. If you call setState within this method, render() will see the updated state and will be executed only once despite the state change.

So you would do something like this:

componentWillMount : function () {
    var data = this.getData();
    this.setState({data : data});
},

This way, render() will only be called once, and you'll have the data you're looking for in the initial render.

if you can dodge the single quotes:

__='
blah blah comment.
'

This is where fnmatch comes very handy:

Probably the best way to do it is using rake to write the tasks you need and the just execute it via command line.

As you mentioned, prompt works for browsers all the way back to IE:

var answer = prompt('question', 'defaultAnswer');

For Node.js > v7.6, you can use console-read-write, which is a wrapper around the low-level readline module:

const io = require('console-read-write');

async function main() {
  // Simple readline scenario
  io.write('I will echo whatever you write!');
  io.write(await io.read());

  // Simple question scenario
  io.write(`hello ${await io.ask('Who are you?')}!`);

  // Since you are not blocking the IO, you can go wild with while loops!
  let saidHi = false;
  while (!saidHi) {
    io.write('Say hi or I will repeat...');
    saidHi = await io.read() === 'hi';
  }

  io.write('Thanks! Now you may leave.');
}

main();
// I will echo whatever you write!
// > ok
// ok
// Who are you? someone
// hello someone!
// Say hi or I will repeat...
// > no
// Say hi or I will repeat...
// > ok
// Say hi or I will repeat...
// > hi
// Thanks! Now you may leave.

For SpiderMonkey, simple readline as suggested by @MooGoo and @Zaz.

It's pretty simple, take a look at the code below:

The form:

<form action="result.php" method="post">
  Answer 1 <input type="radio" name="ans" value="ans1" /><br />
  Answer 2 <input type="radio" name="ans" value="ans2"  /><br />
  Answer 3 <input type="radio" name="ans" value="ans3"  /><br />
  Answer 4 <input type="radio" name="ans" value="ans4"  /><br />
  <input type="submit" value="submit" />
</form>

PHP code:

<?php 

$answer = $_POST['ans'];  
if ($answer == "ans1") {          
    echo 'Correct';      
}
else {
    echo 'Incorrect';
}          
?>

Look at your actual html code and check that the weird symbols are not originating there. This issue came up when I started coding in Notepad++ halfway after coding in Notepad. It seems to me that the older version of Notepad I was using may have used different encoding to Notepad's++ UTF-8 encoding. After I transferred my code from Notepad to Notepad++, the apostrophes got replaced with weird symbols, so I simply had to remove the symbols from my Notepad++ code.

Android follows normal java package conventions plus here is an important snippet of text to read (this is important regarding the wide use of xml files while developing on android).

The reason for having it in reverse order is to do with the layout on the storage media. If you consider each period ('.') in the application name as a path separator, all applications from a publisher would sit together in the path hierarchy. So, for instance, packages from Adobe would be of the form:

com.adobe.reader (Adobe Reader)

com.adobe.photoshop (Adobe Photoshop)

com.adobe.ideas (Adobe Ideas)

[Note that this is just an illustration and these may not be the exact package names.]

These could internally be mapped (respectively) to:

com/adobe/reader

com/adobe/photoshop

com/adobe/ideas

The concept comes from Package Naming Conventions in Java, more about which can be read here:*

http://en.wikipedia.org/wiki/Java_package#Package_naming_conventions

If you have a window which extends javafx.application.Application; you can use the following method. (This will close the whole application, not just the window. I misinterpreted the OP, thanks to the commenters for pointing it out).

Platform.exit();

Example:

public class MainGUI extends Application {
.........

Button exitButton = new Button("Exit");
exitButton.setOnAction(new ExitButtonListener());
.........

public class ExitButtonListener implements EventHandler<ActionEvent> {

  @Override
  public void handle(ActionEvent arg0) {
    Platform.exit();
  }
}

Edit for the beauty of Java 8:

 public class MainGUI extends Application {
    .........

    Button exitButton = new Button("Exit");
    exitButton.setOnAction(actionEvent -> Platform.exit());
 }

You can use the Background Panel class. It does the custom painting as explained above but gives you options to display the image scaled, tiled or normal size. It also explains how you can use a JLabel with an image as the content pane for the frame.

Make sure if root project directory is coming up in sys.path output. If not, please add path of root project directory to sys.path.

I had a very similar issue. I got the same error because the csv contained spaces in the header. My csv contained a header "Gender " and I had it listed as:

[['Gender']]

If it's easy enough for you to access your csv, you can use the excel formula trim() to clip any spaces of the cells.

or remove it like this

df.columns = df.columns.to_series().apply(lambda x: x.strip())

Summary:

1. Step 1

You search your file full path in history of deleted files git log --diff-filter=D --summary | grep filename

2. Step 2

You restore your file from commit before it was deleted

restore () {
  filepath="$@"
  last_commit=$(git log --all --full-history -- $filepath | grep commit | head -1 | awk '{print $2; exit}')
  echo "Restoring file from commit before $last_commit"
  git checkout $last_commit^ -- $filepath
}

restore my/file_path

The short answer is that there is no guaranteed way to get the information you want, however there are heuristics that work almost always in practice. You might look at How do I find the location of the executable in C?. It discusses the problem from a C point of view, but the proposed solutions are easily transcribed into Python.

The correct url is:

file:///android_asset/RELATIVEPATH

where RELATIVEPATH is the path to your resource relative to the assets folder.

Note the 3 /'s in the scheme. Web view would not load any of my assets without the 3. I tried 2 as (previously) commented by CommonsWare and it wouldn't work. Then I looked at CommonsWare's source on github and noticed the extra forward slash.

This testing though was only done on the 1.6 Android emulator but I doubt its different on a real device or higher version.

EDIT: CommonsWare updated his answer to reflect this tiny change. So I've edited this so it still makes sense with his current answer.

$ne

selects the documents where the value of the field is not equal to the specified value. This includes documents that do not contain the field.

User.find({ "username": { "$ne": 'admin' } })

$nin

$nin selects the documents where: the field value is not in the specified array or the field does not exist.

User.find({ "groups": { "$nin": ['admin', 'user'] } })

The funny symbols you're encountering are a UTF-8 BOM (Byte Order Mark). To get rid of them, open the file using the correct encoding (I'm assuming you're on Python 3):

file = open(r"D:\zzzz\names2.txt", "r", encoding="utf-8-sig")

Furthermore, for counting, you can use collections.Counter:

from collections import Counter
wordcount = Counter(file.read().split())

Display them with:

>>> for item in wordcount.items(): print("{}\t{}".format(*item))
...
snake   1
lion    2
goat    2
horse   3

As I understand it, you want the server be able to send messages through from client 1 to client 2. You cannot directly connect two clients because one of the two ends of a WebSocket connection needs to be a server.

This is some pseudocodish JavaScript:

Client:

var websocket = new WebSocket("server address");

websocket.onmessage = function(str) {
  console.log("Someone sent: ", str);
};

// Tell the server this is client 1 (swap for client 2 of course)
websocket.send(JSON.stringify({
  id: "client1"
}));

// Tell the server we want to send something to the other client
websocket.send(JSON.stringify({
  to: "client2",
  data: "foo"
}));

Server:

var clients = {};

server.on("data", function(client, str) {
  var obj = JSON.parse(str);

  if("id" in obj) {
    // New client, add it to the id/client object
    clients[obj.id] = client;
  } else {
    // Send data to the client requested
    clients[obj.to].send(obj.data);
  }
});

Use:

SELECT *
  FROM YOUR_TABLE
 WHERE creation_date <= TRUNC(SYSDATE) - 30

SYSDATE returns the date & time; TRUNC resets the date to being as of midnight so you can omit it if you want the creation_date that is 30 days previous including the current time.

Depending on your needs, you could also look at using ADD_MONTHS:

SELECT *
  FROM YOUR_TABLE
 WHERE creation_date <= ADD_MONTHS(TRUNC(SYSDATE), -1)

In Python 3, you can use

"one" in d.values()

to test if "one" is among the values of your dictionary.

In Python 2, it's more efficient to use

"one" in d.itervalues()

instead.

Note that this triggers a linear scan through the values of the dictionary, short-circuiting as soon as it is found, so this is a lot less efficient than checking whether a key is present.

I found the answers above didn't give me the guidance I needed (I too expected to be in the code for the .java file, and right-click on the tab and see a Refactor option). Here's what I did:

1. Go to the top of the .java module (ctrl+Home)
2. Double-click on the class name that is the same name as the .java module and the class name should now be highlight
3. Right-click the highlighted class name | Open Type Hierarchy. The Type Hierarchy should open showing the class name
4. Right-click the class name in the Type Hierarchy | Refactor | Rename | type the new name in the popup window Rename Type

$dom->@loadHTML($html);

This is incorrect, use this instead:

@$dom->loadHTML($html);

The order() function fails when the column has levels or factor. It works properly when stringsAsFactors=FALSE is used in data.frame creation.

I saw examples of thread IDs like this:

class myThread(threading.Thread):
    def __init__(self, threadID, name, counter):
        self.threadID = threadID
        ...

The threading module docs lists name attribute as well:

...

A thread has a name. 
The name can be passed to the constructor, 
and read or changed through the name attribute.

...

Thread.name

A string used for identification purposes only. 
It has no semantics. Multiple threads may
be given the same name. The initial name is set by the constructor.

JavaScript is a client-side language and your MySQL database is going to be running on a server.

So you have to rename your file to index.php for example (.php is important) so you can use php code for that. It is not very difficult, but not directly possible with html.

(Somehow you can tell your server to let the html files behave like php files, but this is not the best solution.)

So after you renamed your file, go to the very top, before <html> or <!DOCTYPE html> and type:

<?php
    if($_SERVER['REQUEST_METHOD'] == 'POST') {
        /*Creating variables*/
        $name = $_POST["name"];
        $address = $_POST["address"];
        $age = $_POST["age"];


        $dbhost = "localhost"; /*most of the time it's localhost*/
        $username = "yourusername";
        $password = "yourpassword";
        $dbname = "mydatabase";

        $mysql = mysqli_connect($dbhost, $username, $password, $dbname); //It connects
        $query = "INSERT INTO yourtable (name,address,age) VALUES $name, $address, $age";
        mysqli_query($mysql, $query);
    }
?>
<!DOCTYPE html>

        <input name="name" type="text"/>
        <input name="address" type="text"/>
        <input name="age" type="text"/>

in the end i found a solution First, make sure MySQL server is running. Type the following command at a shell prompt:

/etc/init.d/mysql status

If MySQL is not running, enter:

/etc/init.d/mysql start

If MySQL is not installed, type the following command to install MySQL server:

apt-get install mysql-server

Make sure MySQL module for php5 is installed:

dpkg --list | grep php5-mysql

To install php5-mysql module enter:

apt-get install php5-mysql

Next, restart the Apache2 web server:

/etc/init.d/apache2 restart

Sorry, the short answer is no. CSS (2.1) will only mark up the elements of a DOM, not their attributes. You'd have to apply a specific class to each input.

Bummer I know, because that would be incredibly useful.

I know you've said you'd prefer CSS over JavaScript, but you should still consider using jQuery. It provides a very clean and elegant way of adding styles to DOM elements based on attributes.

You can do a couple of things to troubleshoot this issue. First, use Windows file search to search your hard drive for your assembly (.dll). Once you have a list of results, do View->Choose Details... and then check "File Version". This will display the version number in the list of results, so you can see where the old version might be coming from.

Also, like Lars said, check your GAC to see what version is listed there. This Microsoft article states that assemblies found in the GAC are not copied locally during a build, so you might need to remove the old version before doing a rebuild all. (See my answer to this question for notes on creating a batch file to do this for you)

If you still can't figure out where the old version is coming from, you can use the fuslogvw.exe application that ships with Visual Studio to get more information about the binding failures. Microsoft has information about this tool here. Note that you'll have to enable logging by setting the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Fusion\EnableLog registry key to 1.

Try this: Adding users to MySQL

You need grant privileges to the user if you want external acess to database(ie. web pages).

For anyone uninterested in writing their own static null safety method you can use: commons-lang's org.apache.commons.lang.ObjectUtils.defaultIfNull(Object, Object). For example:

    for (final String item : 
    (List<String>)ObjectUtils.defaultIfNull(items, Collections.emptyList())) { ... }

ObjectUtils.defaultIfNull JavaDoc

You can change the behavior of the built in types in Python. For your case it's really easy to create a dict subclass that will store duplicated values in lists under the same key automatically:

class Dictlist(dict):
    def __setitem__(self, key, value):
        try:
            self[key]
        except KeyError:
            super(Dictlist, self).__setitem__(key, [])
        self[key].append(value)

Output example:

>>> d = dictlist.Dictlist()
>>> d['test'] = 1
>>> d['test'] = 2
>>> d['test'] = 3
>>> d
{'test': [1, 2, 3]}
>>> d['other'] = 100
>>> d
{'test': [1, 2, 3], 'other': [100]}

Efficient is a word that depends on context. The solution to this problem depends on the amount of queries performed relative to the amount of insertions. Suppose you are inserting N numbers and K times towards the end you were interested in the median. The heap based algorithm's complexity would be O(N log N + K).

Consider the following alternative. Plunk the numbers in an array, and for each query, run the linear selection algorithm (using the quicksort pivot, say). Now you have an algorithm with running time O(K N).

Now if K is sufficiently small (infrequent queries), the latter algorithm is actually more efficient and vice versa.

I do it like Bradley Braithwaite suggests in his blog:

app
    .factory('searchService', ['$q', '$http', function($q, $http) {
        var service = {};

        service.search = function search(query) {
            // We make use of Angular's $q library to create the deferred instance
            var deferred = $q.defer();

            $http
                .get('http://localhost/v1?=q' + query)
                .success(function(data) {
                    // The promise is resolved once the HTTP call is successful.
                    deferred.resolve(data);
                })
                .error(function(reason) {
                    // The promise is rejected if there is an error with the HTTP call.
                    deferred.reject(reason);
                });

            // The promise is returned to the caller
            return deferred.promise;
        };

        return service;
    }])
    .controller('SearchController', ['$scope', 'searchService', function($scope, searchService) {
        // The search service returns a promise API
        searchService
            .search($scope.query)
            .then(function(data) {
                // This is set when the promise is resolved.
                $scope.results = data;
            })
            .catch(function(reason) {
                // This is set in the event of an error.
                $scope.error = 'There has been an error: ' + reason;
            });
    }])

Key Points:

• The resolve function links to the .then function in our controller i.e. all is well, so we can keep our promise and resolve it.

• The reject function links to the .catch function in our controller i.e. something went wrong, so we can’t keep our promise and need to reject it.

It is quite stable and safe and if you have other conditions to reject the promise you can always filter your data in the success function and call deferred.reject(anotherReason) with the reason of the rejection.

As Ryan Vice suggested in the comments, this may not be seen as useful unless you fiddle a bit with the response, so to speak.

Because success and error are deprecated since 1.4 maybe it is better to use the regular promise methods then and catch and transform the response within those methods and return the promise of that transformed response.

I am showing the same example with both approaches and a third in-between approach:

success and error approach (success and error return a promise of an HTTP response, so we need the help of $q to return a promise of data):

function search(query) {
  // We make use of Angular's $q library to create the deferred instance
  var deferred = $q.defer();

  $http.get('http://localhost/v1?=q' + query)
  .success(function(data,status) {
    // The promise is resolved once the HTTP call is successful.
    deferred.resolve(data);              
  })

  .error(function(reason,status) {
    // The promise is rejected if there is an error with the HTTP call.
    if(reason.error){
      deferred.reject({text:reason.error, status:status});
    }else{
      //if we don't get any answers the proxy/api will probably be down
      deferred.reject({text:'whatever', status:500});
    }
  });

  // The promise is returned to the caller
  return deferred.promise;
};

then and catch approach (this is a bit more difficult to test, because of the throw):

function search(query) {

  var promise=$http.get('http://localhost/v1?=q' + query)

  .then(function (response) {
    // The promise is resolved once the HTTP call is successful.
    return response.data;
  },function(reason) {
    // The promise is rejected if there is an error with the HTTP call.
    if(reason.statusText){
      throw reason;
    }else{
      //if we don't get any answers the proxy/api will probably be down
      throw {statusText:'Call error', status:500};
    }

  });

  return promise;
}

There is a halfway solution though (this way you can avoid the throw and anyway you'll probably need to use $q to mock the promise behavior in your tests):

function search(query) {
  // We make use of Angular's $q library to create the deferred instance
  var deferred = $q.defer();

  $http.get('http://localhost/v1?=q' + query)

  .then(function (response) {
    // The promise is resolved once the HTTP call is successful.
    deferred.resolve(response.data);
  },function(reason) {
    // The promise is rejected if there is an error with the HTTP call.
    if(reason.statusText){
      deferred.reject(reason);
    }else{
      //if we don't get any answers the proxy/api will probably be down
      deferred.reject({statusText:'Call error', status:500});
    }

  });

  // The promise is returned to the caller
  return deferred.promise;
}

Any kind of comments or corrections are welcome.

This is what you have to do

var fileVariable =document.getElementsById('fileId').files[0];

If you want to check for image file types then

if(fileVariable.type.match('image.*'))
{
 alert('its an image');
}

lets put this in a simple term. An element is a set of opening and closing tags in use.

Element

<h1>...</h1>

Tag H1 opening tag

<h1>

H1 closing tag

</h1>

Updating/completing zszep answer:

After copying the request as cUrl (bash), simply import it in the Postman App:

The other answers here are very much correct, and valuable. But sometimes you just want simple: to get a plain old parsed value at directive instantiation, without needing updates, and without messing with isolate scope. For instance, it can be handy to provide a declarative payload into your directive as an array or hash-object in the form:

my-directive-name="['string1', 'string2']"

In that case, you can cut to the chase and just use a nice basic angular.$eval(attr.attrName).

element.val("value = "+angular.$eval(attr.value));

Working Fiddle.

The List<> class does guarantee ordering - things will be retained in the list in the order you add them, including duplicates, unless you explicitly sort the list.

According to MSDN:

...List "Represents a strongly typed list of objects that can be accessed by index."

The index values must remain reliable for this to be accurate. Therefore the order is guaranteed.

You might be getting odd results from your code if you're moving the item later in the list, as your Remove() will move all of the other items down one place before the call to Insert().

Can you boil your code down to something small enough to post?

In MySQL, "Group By" uses an extra step: filesort. I realize DISTINCT is faster than GROUP BY, and that was a surprise.

Just in case someone is lost. For both new application or existing ones go to File->Project Structure. Then in Project settings on the left pane select Project for the Java SDK and select Modules for Android SDK.

You can push an 'empty' reference to the remote tag name:

git push origin :tagname

Or, more expressively, use the --delete option (or -d if your git version is older than 1.8.0):

git push --delete origin tagname

Note that git has tag namespace and branch namespace so you may use the same name for a branch and for a tag. If you want to make sure that you cannot accidentally remove the branch instead of the tag, you can specify full ref which will never delete a branch:

git push origin :refs/tags/tagname

If you also need to delete the local tag, use:

git tag --delete tagname

Background

Pushing a branch, tag, or other ref to a remote repository involves specifying "which repo, what source, what destination?"

git push remote-repo source-ref:destination-ref

A real world example where you push your master branch to the origin's master branch is:

git push origin refs/heads/master:refs/heads/master

Which because of default paths, can be shortened to:

git push origin master:master

Tags work the same way:

git push origin refs/tags/release-1.0:refs/tags/release-1.0

Which can also be shortened to:

git push origin release-1.0:release-1.0

By omitting the source ref (the part before the colon), you push 'nothing' to the destination, deleting the ref on the remote end.

Change Minute parameter to 0.

You can set the cron for every three hours as:

0 */3 * * * your command here ..

int means interrupt, and the number 0x80 is the interrupt number. An interrupt transfers the program flow to whomever is handling that interrupt, which is interrupt 0x80 in this case. In Linux, 0x80 interrupt handler is the kernel, and is used to make system calls to the kernel by other programs.

The kernel is notified about which system call the program wants to make, by examining the value in the register %eax (AT&T syntax, and EAX in Intel syntax). Each system call have different requirements about the use of the other registers. For example, a value of 1 in %eax means a system call of exit(), and the value in %ebx holds the value of the status code for exit().

By using this class you can apply "dashed and underline" effect to multiple lines text. to use DashPathEffect you have to turn off hardwareAccelerated of your TextView(though DashPathEffect method has a problem with long text). you can find my sample project here: https://github.com/jintoga/Dashed-Underlined-TextView/blob/master/Untitled.png.

public class DashedUnderlineSpan implements LineBackgroundSpan, LineHeightSpan {

    private Paint paint;
    private TextView textView;
    private float offsetY;
    private float spacingExtra;

    public DashedUnderlineSpan(TextView textView, int color, float thickness, float dashPath,
                               float offsetY, float spacingExtra) {
        this.paint = new Paint();
        this.paint.setColor(color);
        this.paint.setStyle(Paint.Style.STROKE);
        this.paint.setPathEffect(new DashPathEffect(new float[] { dashPath, dashPath }, 0));
        this.paint.setStrokeWidth(thickness);
        this.textView = textView;
        this.offsetY = offsetY;
        this.spacingExtra = spacingExtra;
    }

    @Override
    public void chooseHeight(CharSequence text, int start, int end, int spanstartv, int v,
                             Paint.FontMetricsInt fm) {
        fm.ascent -= spacingExtra;
        fm.top -= spacingExtra;
        fm.descent += spacingExtra;
        fm.bottom += spacingExtra;
    }

    @Override
    public void drawBackground(Canvas canvas, Paint p, int left, int right, int top, int baseline,
                               int bottom, CharSequence text, int start, int end, int lnum) {
        int lineNum = textView.getLineCount();
        for (int i = 0; i < lineNum; i++) {
            Layout layout = textView.getLayout();
            canvas.drawLine(layout.getLineLeft(i), layout.getLineBottom(i) - spacingExtra + offsetY,
                    layout.getLineRight(i), layout.getLineBottom(i) - spacingExtra + offsetY,
                    this.paint);
        }
    }
}

Result:

Use one way flow syntax property binding:

<div [innerHTML]="comment"></div>

From angular docs: "Angular recognizes the value as unsafe and automatically sanitizes it, which removes the <script> tag but keeps safe content such as the <b> element."

For fetching the name of all tables:

SELECT table_name 
FROM information_schema.tables;

If you need to fetch it for a specific database:

SELECT table_name 
FROM information_schema.tables
WHERE table_schema = 'your_db_name';

Output:

+--------------------+
| table_name         |
+--------------------+
| myapp              |
| demodb             |
| cliquein           |
+--------------------+
3 rows in set (0.00 sec)

As hadley mentioned there are more effective ways of communicating your message than labels in stacked bar charts. In fact, stacked charts aren't very effective as the bars (each Category) doesn't share an axis so comparison is hard.

It's almost always better to use two graphs in these instances, sharing a common axis. In your example I'm assuming that you want to show overall total and then the proportions each Category contributed in a given year.

library(grid)
library(gridExtra)
library(plyr)

# create a new column with proportions
prop <- function(x) x/sum(x)
Data <- ddply(Data,"Year",transform,Share=prop(Frequency))

# create the component graphics
totals <- ggplot(Data,aes(Year,Frequency)) + geom_bar(fill="darkseagreen",stat="identity") + 
  xlab("") + labs(title = "Frequency totals in given Year")
proportion <- ggplot(Data, aes(x=Year,y=Share, group=Category, colour=Category)) 
+ geom_line() + scale_y_continuous(label=percent_format())+ theme(legend.position = "bottom") + 
  labs(title = "Proportion of total Frequency accounted by each Category in given Year")

# bring them together
grid.arrange(totals,proportion)

This will give you a 2 panel display like this:

If you want to add Frequency values a table is the best format.

Here's a nice and simple cache helper class/service I use:

using System.Runtime.Caching;  

public class InMemoryCache: ICacheService
{
    public T GetOrSet<T>(string cacheKey, Func<T> getItemCallback) where T : class
    {
        T item = MemoryCache.Default.Get(cacheKey) as T;
        if (item == null)
        {
            item = getItemCallback();
            MemoryCache.Default.Add(cacheKey, item, DateTime.Now.AddMinutes(10));
        }
        return item;
    }
}

interface ICacheService
{
    T GetOrSet<T>(string cacheKey, Func<T> getItemCallback) where T : class;
}

Usage:

cacheProvider.GetOrSet("cache key", (delegate method if cache is empty));

Cache provider will check if there's anything by the name of "cache id" in the cache, and if there's not, it will call a delegate method to fetch data and store it in cache.

Example:

var products=cacheService.GetOrSet("catalog.products", ()=>productRepository.GetAll())

var array = new Uint8Array(100);    
array[10] = 256;
array[10] === 0 // true

I verified in firefox and chrome, its really an array of bytes :

var array = new Uint8Array(1024*1024*50);  // allocates 50MBytes

If you are using Spring Boot, your main app should be like this (just to make and understand things in simple way) -

package aaa.bbb.ccc;
@SpringBootApplication
@ComponentScan({ "aaa.bbb.ccc.*" })
public class Application {
.....

Make sure you have @Repository and @Service appropriately annotated.

Make sure all your packages fall under - aaa.bbb.ccc.*

In most cases this setup resolves these kind of trivial issues. Here is a full blown example. Hope it helps.

It depends on your IDE or compiler.

Here is a list for Eclipse Galileo:

• all to suppress all warnings
• boxing to suppress warnings relative to boxing/unboxing operations
• cast to suppress warnings relative to cast operations
• dep-ann to suppress warnings relative to deprecated annotation
• deprecation to suppress warnings relative to deprecation
• fallthrough to suppress warnings relative to missing breaks in switch statements
• finally to suppress warnings relative to finally block that don’t return
• hiding to suppress warnings relative to locals that hide variable
• incomplete-switch to suppress warnings relative to missing entries in a switch statement (enum case)
• nls to suppress warnings relative to non-nls string literals
• null to suppress warnings relative to null analysis
• restriction to suppress warnings relative to usage of discouraged or forbidden references
• serial to suppress warnings relative to missing serialVersionUID field for a serializable class
• static-access to suppress warnings relative to incorrect static access
• synthetic-access to suppress warnings relative to unoptimized access from inner classes
• unchecked to suppress warnings relative to unchecked operations

• sync-override to suppress warnings because of missing synchronize when overriding a synchronized method

Kepler and Luna use the same token list as Juno (list).

Others will be similar but vary.

Recommend use: pathinfo with PATHINFO_FILENAME

$filename = 'abc_123_filename.html';
$without_extension = pathinfo($filename, PATHINFO_FILENAME);

git checkout -f your_branch_name

git checkout -f your_branch_name

if you have troubles reverting changes:

git checkout .

if you want to remove untracked directories and files:

git clean -fd

One thing that i didn't see in other answers is To clarify another answers that there is a difference between returning std::unique_ptr that has been created within a function, and one that has been given to that function.

The example could be like this:

class Test
{int i;};
std::unique_ptr<Test> foo1()
{
    std::unique_ptr<Test> res(new Test);
    return res;
}
std::unique_ptr<Test> foo2(std::unique_ptr<Test>&& t)
{
    // return t;  // this will produce an error!
    return std::move(t);
}

//...
auto test1=foo1();
auto test2=foo2(std::unique_ptr<Test>(new Test));

There could be one of the following reasons:

1. You need make an entry in the Amazon Security Group to allow remote access from your machine to Amazon EC2 instance. :- I believe this is done by you as from your question it seems like you already made an entry with 0.0.0.0, which allows everybody to access the machine.
2. MySQL not allowing user to connect from remote machine:- By default MySql creates root user id with admin access. But root id's access is limited to localhost only. This means that root user id with correct password will not work if you try to access MySql from a remote machine. To solve this problem, you need to allow either the root user or some other DB user to access MySQL from remote machine. I would not recommend allowing root user id accessing DB from remote machine. You can use wildcard character % to specify any remote machine.
3. Check if machine's local firewall is not enabled. And if its enabled then make sure that port 3306 is open.

Please go through following link: How Do I Enable Remote Access To MySQL Database Server?

<a href="1.html"><input type="text" class="button_active" value="1"></a>
<a href="2.html"><input type="text" class="button" value="2"></a>
<a href="3.html"><input type="text" class="button" value="3"></a>

Try that. Unless you truly need to stick with the type as submit, then what I provided should work. If you are going to stick with submit, then everything mentioned above is correct, it makes no sense.

"The following SDK components were not installed: sys-img-x86-addon-google_apis-google-22 and addon-google_apis-google-22".

I would suggest just close the window instead of clicking Finish and select not to run the setup wizard.

Solution for this issue is:

1. Create another connection manager for your excel or flat files else you just have to pass variable values in connection string:

2. Right Click on Connection Manager>>properties>>Expression >>Select "ConnectionString" from drop down and pass the input variable like path , filename ..

Do you mean to property files located in src/main/resources? Then you should exclude them using the maven-resource-plugin. See the following page for details:

http://maven.apache.org/plugins/maven-resources-plugin/examples/include-exclude.html

You may also use math.log1p.

According to the official documentation :

math.log1p(x)

Return the natural logarithm of 1+x (base e). The result is calculated in a way which is accurate for x near zero.

You may convert back to the original value using math.expm1 which returns e raised to the power x, minus 1.

The length function will do it. See http://www.techonthenet.com/oracle/functions/length.php

I'm the main author of jblas and wanted to point out that I've released Version 1.0 in late December 2009. I worked a lot on the packaging, meaning that you can now just download a "fat jar" with ATLAS and JNI libraries for Windows, Linux, Mac OS X, 32 and 64 bit (except for Windows). This way you will get the native performance just by adding the jar file to your classpath. Check it out at http://jblas.org!

Why do you use Restrictions.like(...)?

You should use Restrictions.eq(...).

Note you can also use .le, .lt, .ge, .gt on date objects as comparison operators. LIKE operator is not appropriate for this case since LIKE is useful when you want to match results according to partial content of a column. Please see http://www.sql-tutorial.net/SQL-LIKE.asp for the reference.

For example if you have a name column with some people's full name, you can do where name like 'robert %' so that you will return all entries with name starting with 'robert ' (% can replace any character).

In your case you know the full content of the date you're trying to match so you shouldn't use LIKE but equality. I guess Hibernate doesn't give you any exception in this case, but anyway you will probably have the same problem with the Restrictions.eq(...).

Your date object you got with the code:

SimpleDateFormat formatter = new SimpleDateFormat("dd-MM-YYYY");
String myDate = "17-04-2011";
Date date = formatter.parse(myDate);

This date object is equals to the 17-04-2011 at 0h, 0 minutes, 0 seconds and 0 nanoseconds.

This means that your entries in database must have exactly that date. What i mean is that if your database entry has a date "17-April-2011 19:20:23.707000000", then it won't be retrieved because you just ask for that date: "17-April-2011 00:00:00.0000000000".

If you want to retrieve all entries of your database from a given day, you will have to use the following code:

    SimpleDateFormat formatter = new SimpleDateFormat("dd-MM-YYYY");
    String myDate = "17-04-2011";
    // Create date 17-04-2011 - 00h00
    Date minDate = formatter.parse(myDate);
    // Create date 18-04-2011 - 00h00 
    // -> We take the 1st date and add it 1 day in millisecond thanks to a useful and not so known class
    Date maxDate = new Date(minDate.getTime() + TimeUnit.DAYS.toMillis(1));
    Conjunction and = Restrictions.conjunction();
    // The order date must be >= 17-04-2011 - 00h00
    and.add( Restrictions.ge("orderDate", minDate) );
    // And the order date must be < 18-04-2011 - 00h00
    and.add( Restrictions.lt("orderDate", maxDate) ); 

You can use:

try:
   # get your models
except ObjectDoesNotExist:
   # do something

Did you import it? Importing matplotlib is not enough.

>>> import matplotlib
>>> matplotlib.pyplot
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'module' object has no attribute 'pyplot'

but

>>> import matplotlib.pyplot
>>> matplotlib.pyplot

works.

pyplot is a submodule of matplotlib and not immediately imported when you import matplotlib.

The most common form of importing pyplot is

import matplotlib.pyplot as plt

Thus, your statements won't be too long, e.g.

plt.plot([1,2,3,4,5])

instead of

matplotlib.pyplot.plot([1,2,3,4,5])

And: pyplot is not a function, it's a module! So don't call it, use the functions defined inside this module instead. See my example above

You can use getComputedStyle().

var element = document.getElementById('image_1'),
    style = window.getComputedStyle(element),
    top = style.getPropertyValue('top');

jsFiddle.

Although this may be more complicated/heavier-weight than you want, one very flexible way to do it is using something like Expect (or one of the derivatives in another programming language).

Expect is a language designed specifically to control text-based applications, which is exactly what you are looking to do. If you end up needing to do something more complicated (like with logic to actually decide what to do/answer next), Expect is the way to go.

Convert.ToInt32 is the best way to convert
