I have the same problem with python 3.8.5 using venv,vscode 1.48.2 I found my solution. In (env folder)/lib/site-packages does not contains the packages. I use this setting (.vscode/settings.json)

   {
        "python.autoComplete.extraPaths": [
            "./**",
        ],
        "python.pythonPath": "env\\Scripts\\python.exe",
        "python.languageServer": "Microsoft"
   }

Submodule repositories stay in a detached HEAD state pointing to a specific commit. Changing that commit simply involves checking out a different tag or commit then adding the change to the parent repository.

$ cd submodule
$ git checkout v2.0
Previous HEAD position was 5c1277e... bumped version to 2.0.5
HEAD is now at f0a0036... version 2.0

git-status on the parent repository will now report a dirty tree:

# On branch dev [...]
#
#   modified:   submodule (new commits)

Add the submodule directory and commit to store the new pointer.

You can use advanced string formatting, available in Python 2.6 and Python 3.x:

incoming = 'arbit'
result = '{0} hello world {0} hello world {0}'.format(incoming)

I use a combination of add() and endOf() with moment

//...
const today = moment().endOf('day')
const tomorrow = moment().add(1, 'day').endOf('day')

if (date < today) return 'today'
if (date < tomorrow) return 'tomorrow'
return 'later'
//...

The solution for multi-indexes is inside jezrael's cyclopedic answer, but it took me a while to find it so I am posting a new answer:

df.index.names gives the names of a multi-index (as a Frozenlist).

From what I understand they are independent of one another. By keeping the session timeout less than or equal to the authentication timeout, you can make sure any user-specific session variables are not persisted after the authentication has timed out (if that is your concern, which I think is the normal one when asking this question). Of course, you'll have to manually handle the disposal of session variables upon log-out.

Here is a decent response that may answer your question or at least point you in the right direction:

• Forms Authentication Timeout vs Session Timeout

My company has us using FortiClient VPN, which caused this error to occur.

Try disconnecting from your VPN if applicable, and try again.

I prefer using .env file for different environment.

1. Use webpack.dev.config to copy env.dev to .env into root folder
2. Use webpack.prod.config to copy env.prod to .env

and in code

use

require('dotenv').config(); const API = process.env.API ## which will store the value from .env file

try{
    // ...
} catch (...) {
    // ...
}

will catch all C++ exceptions, but it should be considered bad design. You can use c++11's new current_exception mechanism, but if you don't have the ability to use c++11 (legacy code systems requiring a rewrite), then you have no named exception pointer to use to get a message or name. You may want to add separate catch clauses for the various exceptions you can catch, and only catch everything at the bottom to record an unexpected exception. E.g.:

try{
    // ...
} catch (const std::exception& ex) {
    // ...
} catch (const std::string& ex) {
    // ...
} catch (...) {
    // ...
}

You seem to look for the input attribute value, "the initial value of the control"?

<input type="text" value="Morlodenhof 7" />

Double brackets accesses a list element, while a single bracket gives you back a list with a single element.

lst <- list('one','two','three')

a <- lst[1]
class(a)
## returns "list"

a <- lst[[1]]
class(a)
## returns "character"

@since 2.10 version we can use JsonMapper.Builder and accepted answer could look like:

JsonMapper mapper = JsonMapper.builder()
    .visibility(PropertyAccessor.FIELD, JsonAutoDetect.Visibility.ANY)
    .visibility(PropertyAccessor.GETTER, JsonAutoDetect.Visibility.NONE)
    .visibility(PropertyAccessor.SETTER, JsonAutoDetect.Visibility.NONE)
    .visibility(PropertyAccessor.CREATOR, JsonAutoDetect.Visibility.NONE)
    .build();

It's impossible to say without seeing your actual code. Likely the reason is a code path through your function that doesn't execute a return statement. When the code goes down that path, the function ends with no value returned, and so returns None.

Updated: It sounds like your code looks like this:

def b(self, p, data): 
    current = p 
    if current.data == data: 
        return True 
    elif current.data == 1:
        return False 
    else: 
        self.b(current.next, data)

That else clause is your None path. You need to return the value that the recursive call returns:

    else:
        return self.b(current.next, data)

BTW: using recursion for iterative programs like this is not a good idea in Python. Use iteration instead. Also, you have no clear termination condition.

As Java has no pointer data types, it is impossible to use pointers in Java. Even the few experts will not be able to use pointers in java.

Using is_numeric or intval is likely the best way to validate a number here, but to answer your question you could try using preg_replace instead. This example removes all non-numeric characters:

$output = preg_replace( '/[^0-9]/', '', $string );

If the "Customer don't want to install and buy MS Office on a server not at any price", then you cannot use Excel ... But I cannot get the trick: it's all about one basic Office licence which costs something like 150 USD ... And I guess that spending time finding an alternative will cost by far more than this amount!

We had the same problem. In our case, the browser was blocked by a login popup (Windows authentication), so not returning after 60 seconds. Adding correct access rights to the Windows account Chrome was running under solved the problem.

Another option: when cell type is unknown at compile time and cell is formatted as Date Range.Value returns a desired DateTime object.

public static DateTime? GetAsDateTimeOrDefault(Range cell)
{
    object cellValue = cell.Value;
    if (cellValue is DateTime result)
    {
        return result;
    }
    return null;
}

grep will print any lines matching the pattern you provide. If you only want to print the part of the line that matches the pattern, you can pass the -o option:

-o, --only-matching Print only the matched (non-empty) parts of a matching line, with each such part on a separate output line.

Like this:

echo 'Here is a line mentioning 99% somewhere' | grep -o '[0-9]+'

conda doesn't support this directly because it installs from binaries, whereas git install would be from source. conda build does support recipes that are built from git. On the other hand, if all you want to do is keep up-to-date with the latest and greatest of a package, using pip inside of Anaconda is just fine, or alternately, use setup.py develop against a git clone.

This is the reason why Factory Patterns and other creational patterns are so popular in Java. You are correct that without them Java doesn't provide an out of the box mechanism for easy abstraction of instantiation. Still, you get abstraction everywhere where you don't create an object in your method, which should be most of your code.

As an aside, I generally encourage people to not follow the "IRealname" mechanism for naming interfaces. That's a Windows/COM thing that puts one foot in the grave of Hungarian notation and really isn't necessary (Java is already strongly typed, and the whole point of having interfaces is to have them as largely indistinguishable from class types as possible).

FAT32 along with FAT16 and FAT12 are File System Types, but vfat along with umsdos and msdos are drivers, used to mount the FAT file systems in Linux. The choosing of the driver determines how some of the features are applied to the file system, for example, systems mounted with msdos driver don't have long filenames (they are 8.3 format). vfat is the most common driver for mounting FAT32 file systems nowadays.

Source: this wikipedia article

Output of commands like df and lsblk indeed show vfat as the File System Type. But sudo file -sL /dev/<partition> shows FAT (32 bit) if a File System is FAT32.

You can confirm vfat is a module and not a File System Type by running modinfo vfat.

More wordy, but it may benefit SEO, and it will look like nice simple text with CSS disabled.

you can use sorted() method if you want it to return the sorted list. It's more convenient.

l1 = []
n = int(input())

for i in range(n):
  user = int(input())
  l1.append(user)
sorted(l1,reverse=True)

list.sort() method modifies the list in-place and returns None.

if you still want to use sort you can do this.

l1 = []
n = int(input())

for i in range(n):
  user = int(input())
  l1.append(user)
l1.sort(reverse=True)
print(l1)

No; instances of class File represent a path in a filesystem. Therefore, you can use that function only with a file. But perhaps there is an overload that takes an InputStream instead?

Here are the changes that I had to make to the accepted answer when I did this with an image as the centre element:

1. Make sure the image is enclosed within a div (#center in this case). If it isn't, you'll have to set display to block, and it seems to centre relative to the space between the floated elements.

2. Make sure to set the size of both the image and its container:

   #center {
       margin: 0 auto;
   }
   
   #center, #center > img {
       width: 100px;
       height: auto;
   }

If you want to use bootstrap dropdowns, I will recommend this for angular2:

ngx-dropdown

You should target the smallest, not the largest, supported pixel resolution by the devices your app can run on.

Say if there's an actual Mac computer that can run OS X 10.9 and has a native screen resolution of only 1280x720 then that's the resolution you should focus on. Any higher and your game won't correctly run on this device and you could as well remove that device from your supported devices list.

You can rely on upscaling to match larger screen sizes, but you can't rely on downscaling to preserve possibly important image details such as text or smaller game objects.

The next most important step is to pick a fitting aspect ratio, be it 4:3 or 16:9 or 16:10, that ideally is the native aspect ratio on most of the supported devices. Make sure your game only scales to fit on devices with a different aspect ratio.

You could scale to fill but then you must ensure that on all devices the cropped areas will not negatively impact gameplay or the use of the app in general (ie text or buttons outside the visible screen area). This will be harder to test as you'd actually have to have one of those devices or create a custom build that crops the view accordingly.

Alternatively you can design multiple versions of your game for specific and very common screen resolutions to provide the best game experience from 13" through 27" displays. Optimized designs for iMac (desktop) and a Macbook (notebook) devices make the most sense, it'll be harder to justify making optimized versions for 13" and 15" plus 21" and 27" screens.

But of course this depends a lot on the game. For example a tile-based world game could simply provide a larger viewing area onto the world on larger screen resolutions rather than scaling the view up. Provided that this does not alter gameplay, like giving the player an unfair advantage (specifically in multiplayer).

You should provide @2x images for the Retina Macbook Pro and future Retina Macs.

Convert Date To String

I got this error when using the Atom editor and mingw (through a package called gpp-compiler) for C++. Closing the open console window fixed my issue.

Here's my code (not optimized but a full working example):

<head>

var offX = 15;          // X offset from mouse position
var offY = 15;          // Y offset from mouse position

function mouseX(evt) {if (!evt) evt = window.event; if (evt.pageX) return evt.pageX; else if (evt.clientX)return evt.clientX + (document.documentElement.scrollLeft ?  document.documentElement.scrollLeft : document.body.scrollLeft); else return 0;}

function follow(evt) {
    var obj = document.getElementById(divName).style;
    obj.left = (parseInt(mouseX(evt))+offX) + 'px';

Above answer can be considered to be confusing a little. String methods are not modifying original object. They return new object. It must be:

var str = "Sonic Free Games";
str = str.replace(/\s+/g, '-').toLowerCase(); //new object assigned to var str

Speed

SUMPRODUCT is faster than SUM arrays, i.e. having {} arrays in the SUM function. SUMIFS is 30% faster than SUMPRODUCT.

{SUM(SUMIFS({}))} vs SUMPRODUCT(SUMIFS({})) both works fine, but SUMPRODUCT feels a bit easier to write without the CTRL-SHIFT-ENTER to create the {}.

Preference

I personally prefer writing SUMPRODUCT(--(ISNUMBER(MATCH(...)))) over SUMPRODUCT(SUMIFS({})) for multiple criteria.

However, if you have a drop-down menu where you want to select specific characteristics or all, SUMPRODUCT(SUMIFS()), is the only way to go. (as for selecting "all", the value should enter in "<>" + "Whatever word you want as long as it's not part of the specific characteristics".

All the answers on this page assume that the map occupies the full screen. I actually have a HUD display (ie buttons scattered at the top and bottom) that give information ontop of the map.. and so the algorithms on the page will display the pins all right, but some of them will appear under the HUD display buttons.

My solution zooms the map in to display the annotations in a subset of the screen and works for different screen sizes (ie 3.5" vs 4.0" etc):

// create a UIView placeholder and throw it on top of the original mapview
// position the UIView to fit the maximum area not hidden by the HUD display buttons
// add an *other* mapview in that uiview, 
// get the MKCoordinateRegion that fits the pins from that fake mapview
// kill the fake mapview and set the region of the original map 
// to that MKCoordinateRegion.

Here is what I did in code (note: i use NSConstraints with some helper methods to make my code work in different screen sizes.. while the code is quite readable.. my answer here explains it better.. it's basically the same workflow:)

// position smallerMap to fit available space
// don't store this map, it will slow down things if we keep it hidden or even in memory
[@[_smallerMapPlaceholder] mapObjectsApplyingBlock:^(UIView *view) {
    [view removeFromSuperview];
    [view setTranslatesAutoresizingMaskIntoConstraints:NO];
    [view setHidden:NO];
    [self.view addSubview:view];
}];

NSDictionary *buttonBindingDict = @{ @"mapPlaceholder": _smallerMapPlaceholder};

NSArray *constraints = [@[@"V:|-225-[mapPlaceholder(>=50)]-176-|",
                          @"|-40-[mapPlaceholder(<=240)]-40-|"
                          ] mapObjectsUsingBlock:^id(NSString *formatString, NSUInteger idx){
                              return [NSLayoutConstraint constraintsWithVisualFormat:formatString options:0 metrics:nil views:buttonBindingDict];
                          }];

[self.view addConstraints:[constraints flattenArray]];
[self.view layoutIfNeeded];

MKMapView *smallerMap = [[MKMapView alloc] initWithFrame:self.smallerMapPlaceholder.frame];
[_smallerMapPlaceholder addSubview:smallerMap];

MKCoordinateRegion regionThatFits = [smallerMap getRegionThatFits:self.mapView.annotations];
[smallerMap removeFromSuperview];
smallerMap = nil;
[_smallerMapPlaceholder setHidden:YES];

[self.mapView setRegion:regionThatFits animated:YES];

here is the code that gets region that fits:

- (MKCoordinateRegion)getRegionThatFits:(NSArray *)routes {
    MKCoordinateRegion region;
    CLLocationDegrees maxLat = -90.0;
    CLLocationDegrees maxLon = -180.0;
    CLLocationDegrees minLat = 90.0;
    CLLocationDegrees minLon = 180.0;
    for(int idx = 0; idx < routes.count; idx++)
    {
        CLLocation* currentLocation = [routes objectAtIndex:idx];
        if(currentLocation.coordinate.latitude > maxLat)
            maxLat = currentLocation.coordinate.latitude;
        if(currentLocation.coordinate.latitude < minLat)
            minLat = currentLocation.coordinate.latitude;
        if(currentLocation.coordinate.longitude > maxLon)
            maxLon = currentLocation.coordinate.longitude;
        if(currentLocation.coordinate.longitude < minLon)
            minLon = currentLocation.coordinate.longitude;
    }
    region.center.latitude     = (maxLat + minLat) / 2.0;
    region.center.longitude    = (maxLon + minLon) / 2.0;
    region.span.latitudeDelta = 0.01;
    region.span.longitudeDelta = 0.01;

    region.span.latitudeDelta  = ((maxLat - minLat)<0.0)?100.0:(maxLat - minLat);
    region.span.longitudeDelta = ((maxLon - minLon)<0.0)?100.0:(maxLon - minLon);

    MKCoordinateRegion regionThatFits = [self regionThatFits:region];
    return regionThatFits;
}

Use the following code:

foreach (string line in File.ReadAllLines(fileName))

This was a HUGE difference in reading performance.

It comes at the cost of memory consumption, but totally worth it!

To complement the existing helpful answers:

Using Bash's own regex-matching operator, =~, is a faster alternative in this case, given that you're only matching a single value already stored in a variable:

set -- '12-34-5678' # set $1 to sample value

kREGEX_DATE='^[0-9]{2}[-/][0-9]{2}[-/][0-9]{4}$' # note use of [0-9] to avoid \d
[[ $1 =~ $kREGEX_DATE ]]
echo $? # 0 with the sample value, i.e., a successful match

Note, however, that the caveat re using flavor-specific regex constructs such as \d equally applies: While =~ supports EREs (extended regular expressions), it also supports the host platform's specific extension - it's a rare case of Bash's behavior being platform-dependent.

To remain portable (in the context of Bash), stick to the POSIX ERE specification.

Note that =~ even allows you to define capture groups (parenthesized subexpressions) whose matches you can later access through Bash's special ${BASH_REMATCH[@]} array variable.

Further notes:

• $kREGEX_DATE is used unquoted, which is necessary for the regex to be recognized as such (quoted parts would be treated as literals).

• While not always necessary, it is advisable to store the regex in a variable first, because Bash has trouble with regex literals containing \.

  • E.g., on Linux, where \< is supported to match word boundaries, [[ 3 =~ \<3 ]] && echo yes doesn't work, but re='\<3'; [[ 3 =~ $re ]] && echo yes does.

• I've changed variable name REGEX_DATE to kREGEX_DATE (k signaling a (conceptual) constant), so as to ensure that the name isn't an all-uppercase name, because all-uppercase variable names should be avoided to prevent conflicts with special environment and shell variables.

If you are facing this issue while using Kotlin and have

kotlin.incremental=true
kapt.incremental.apt=true

in the gradle.properties, then you need to remove this temporarily to fix the build.

After the successful build, you can again add these properties to speed up the build time while using Kotlin.

I think, you can use objects as params-transportes, too.

$myParam = new stdClass();
$myParam->optParam2 = 'something';
$myParam->optParam8 = 3;
theFunction($myParam);

function theFunction($fparam){      
  return "I got ".$fparam->optParam8." of ".$fparam->optParam2." received!";
}

Of course, you have to set default values for "optParam8" and "optParam2" in this function, in other case you will get "Notice: Undefined property: stdClass::$optParam2"

If using arrays as function parameters, I like this way to set default values:

function theFunction($fparam){
   $default = array(
      'opt1' => 'nothing',
      'opt2' => 1
   );
   if(is_array($fparam)){
      $fparam = array_merge($default, $fparam);
   }else{
      $fparam = $default;
   }
   //now, the default values are overwritten by these passed by $fparam
   return "I received ".$fparam['opt1']." and ".$fparam['opt2']."!";
}

If you're using Symfony 2 security management, you don't need to get posted values, you only need to manage form template (see documentation).

If you aren't using Symfony 2 security management, I advise you strongly to use it. If you don't want to or if you can't, can you give us the LoginType's sources ?

let firstname = "paresh"
let lastname = "hirpara"
let itsme = "\(firstname) \(lastname)"

I agree with squelart. Incrementing two variables is bug prone, especially if you only test for one of them.

This is the readable way to do this:

int j = 0;
for(int i = 0; i < 5; ++i) {
    do_something(i, j);
    ++j;
}

For loops are meant for cases where your loop runs on one increasing/decreasing variable. For any other variable, change it in the loop.

If you need j to be tied to i, why not leave the original variable as is and add i?

for(int i = 0; i < 5; ++i) {
    do_something(i,a+i);
}

If your logic is more complex (for example, you need to actually monitor more than one variable), I'd use a while loop.

An inner class, by definition, cannot be static, so I am going to recast your question as "What is the difference between static and non-static nested classes?"

A non-static nested class has full access to the members of the class within which it is nested. A static nested class does not have a reference to a nesting instance, so a static nested class cannot invoke non-static methods or access non-static fields of an instance of the class within which it is nested.

Preinstalled applications are in /system/app folder. User installed applications are in /data/app. I guess you can't access unless you have a rooted phone. I don't have a rooted phone here but try this code out:

public class Testing extends Activity {
    private static final String TAG = "TEST";
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        File appsDir = new File("/data/app");

        String[] files = appsDir.list();

        for (int i = 0 ; i < files.length ; i++ ) {
            Log.d(TAG, "File: "+files[i]);

        }
    }

It does lists the apks in my rooted htc magic and in the emu.

You can do the following. Add your ggplot code after the first line of code and end with dev.off().

tiff("test.tiff", units="in", width=5, height=5, res=300)
# insert ggplot code
dev.off()

res=300 specifies that you need a figure with a resolution of 300 dpi. The figure file named 'test.tiff' is saved in your working directory.

Change width and height in the code above depending on the desired output.

Note that this also works for other R plots including plot, image, and pheatmap.

Other file formats

In addition to TIFF, you can easily use other image file formats including JPEG, BMP, and PNG. Some of these formats require less memory for saving.

Further to @and_rest answer, this is how I clone the children and add a class.

<div className="parent">
    {React.Children.map(this.props.children, child => React.cloneElement(child, {className:'child'}))}
</div>

From the official documentation:

As of PHP 5.2.2, DateTime objects can be compared using comparison operators.

$date1 = new DateTime("now");
$date2 = new DateTime("tomorrow");

var_dump($date1 == $date2); // false
var_dump($date1 < $date2); // true
var_dump($date1 > $date2); // false

For PHP versions before 5.2.2 (actually for any version), you can use diff.

$datetime1 = new DateTime('2009-10-11'); // 11 October 2013
$datetime2 = new DateTime('2009-10-13'); // 13 October 2013

$interval = $datetime1->diff($datetime2);
echo $interval->format('%R%a days'); // +2 days

You can concat origin and pathname, if theres present a port such as example.com:80, that will be included as well.

location.origin + location.pathname

The boolean values are compiled to int data type in JVM. See here.

You want the :checkbox:checked selector and map to create an array of the values:

var checkedValues = $('input:checkbox:checked').map(function() {
    return this.value;
}).get();

If your checkboxes have a shared class it would be faster to use that instead, eg. $('.mycheckboxes:checked'), or for a common name $('input[name="Foo"]:checked')

- Update -

If you don't need IE support then you can now make the map() call more succinct by using an arrow function:

var checkedValues = $('input:checkbox:checked').map((i, el) => el.value).get();

I agree with Ajeesh, but there are simpler ways to do this...

if ($maker == "2") { }

or

if ($maker == 2) { }

• Why am I not returning a "Toyota" value? Because the "Toyota" choice in the Selection Box would have already returned "2", which, would indicate that the selected Manufacturer in the Selection Box would be Toyota.

• How would the user know if the value is equal to the Toyota selection in the Selection Box? In between my example code's brackets, you would put $maker = "Toyota" then echo $maker, or create a new string, like so: $maketwo = "Toyota" then you can echo $makertwo (I much prefer creating a new string, rather than overwriting $maker's original value.)

• If the user selects "Nissan", will the example code take care of that as well..? Yes, and no. While "Toyota" would return value "2", "Nissan" would instead return value "3". The current set value that the example code is looking for is "2", which means that if the user selects "Nissan", which represents value "3", then presses "Search", the example code would not be executed. You can easily change the code to check for value "3", or value "1", which represents "--Any--".

• What if the user clicks "Search" while the Selection Box is set to "Select Manufacturer"? How can I prevent them from doing so? To prevent them from proceeding any further, change the set value of the example code to "0", and in between the brackets, you may place your code, then after that, add return;, which terminates all execution of any further code within the function / statement.

this works well for me

    arglen=$#
    argparam=$*
    if [ $arglen -eq '3' ];
    then
            echo Valid Number of arguments
            echo "Arguments are $*"
    else
            echo only four arguments are allowed
    fi

If you want "physical" access, we're developing this API that will eventually allows you to communicate with storage devices. It's open source and you can see the current code for some information. Check back for more features: https://github.com/virtium/vtStor

The browser is preventing you from cross-site scripting.

If the url is outside of your domain, then you need to do this on the server side or move it into your domain.

They are parts of the Observer design pattern. Usually one or more obervers get informed about changes in one observable. It's a notifcation that "something" happened, where you as a programmer can define what "something" means.

When using this pattern, you decouple the both entities from each another - the observers become pluggable.

You can solve it by symbolic link.

unlink /usr/local/bin/python
ln -s /usr/local/bin/python3.3 /usr/local/bin/python

I got the same question here. If the document is huge, it is not a good idea to use XmlDocument. The fact is that the first element is the root element, based on which XmlReader can be used to get the root element. Using XmlReader will be much more efficient than using XmlDocument as it doesn't require load the whole document into memory.

  using (XmlReader reader = XmlReader.Create(<your_xml_file>)) {
    while (reader.Read()) {
      // first element is the root element
      if (reader.NodeType == XmlNodeType.Element) {
        System.Console.WriteLine(reader.Name);
        break;
      }
    }
  }

Have you activated your environment? Also you could try this: vscode select venv

I've had success with the following personally, but my function should probably be called something like 'ensure this directory exists':

def mkdirRecursive(dirpath):
    import os
    if os.path.isdir(dirpath): return

    h,t = os.path.split(dirpath) # head/tail
    if not os.path.isdir(h):
        mkdirRecursive(h)

    os.mkdir(join(h,t))
# end mkdirRecursive

i had same issue i resolve this use under

go to gmail.com

my account

and enable

Allow less secure apps: ON

it start works

I have encountered a similar issue a couple of times. Normally I just do a fresh installation of PostgreSQL following this tutorial and that solves the problem at the expense of losing data.

I was determined on getting real fix today. Restarting PostgreSQL resolved it on ubuntu. sudo /etc/init.d/postgresql restart

Most of the roles you see were defined as part of ARIA 1.0, and then later incorporated into HTML via supporting specs like HTML-AAM. Some of the new HTML5 elements (dialog, main, etc.) are even based on the original ARIA roles.

http://www.w3.org/TR/wai-aria/

There are a few primary reasons to use roles in addition to your native semantic element.

Reason #1. Overriding the role where no host language element is appropriate or, for various reasons, a less semantically appropriate element was used.

In this example, a link was used, even though the resulting functionality is more button-like than a navigation link.

<a href="#" role="button" aria-label="Delete item 1">Delete</a>
<!-- Note: href="#" is just a shorthand here, not a recommended technique. Use progressive enhancement when possible. -->

Screen readers users will hear this as a button (as opposed to a link), and you can use a CSS attribute selector to avoid class-itis and div-itis.

[role="button"] {
  /* style these as buttons w/o relying on a .button class */
}

[Update 7 years later: removed the * selector to make some commenters happy, since the old browser quirk that required universal selector on attribute selectors is unnecessary in 2020.]

Reason #2. Backing up a native element's role, to support browsers that implemented the ARIA role but haven't yet implemented the native element's role.

For example, the "main" role has been supported in browsers for many years, but it's a relatively recent addition to HTML5, so many browsers don't yet support the semantic for <main>.

<main role="main">…</main>

This is technically redundant, but helps some users and doesn't harm any. In a few years, this technique will likely become unnecessary for main.

Reason #3. Update 7 years later (2020): As at least one commenter pointed out, this is now very useful for custom elements, and some spec work is underway to define the default accessibility role of a web component. Even if/once that API is standardized, there may be need to override the default role of a component.

Note/Reply

You also wrote:

I see some people make up their own. Is that allowed or a correct use of the role attribute?

That's an allowed use of the attribute unless a real role is not included. Browsers will apply the first recognized role in the token list.

<span role="foo link note bar">...</a>

Out of the list, only link and note are valid roles, and so the link role will be applied in the platform accessibility API because it comes first. If you use custom roles, make sure they don't conflict with any defined role in ARIA or the host language you're using (HTML, SVG, MathML, etc.)

I think the asker wants to use watch with Vuex.

this.$store.watch(
      (state)=>{
        return this.$store.getters.your_getter
      },
      (val)=>{
       //something changed do something

      },
      {
        deep:true
      }
      );

TLDR; Pandas groupby.agg has a new, easier syntax for specifying (1) aggregations on multiple columns, and (2) multiple aggregations on a column. So, to do this for pandas >= 0.25, use

df.groupby('dummy').agg(Mean=('returns', 'mean'), Sum=('returns', 'sum'))

           Mean       Sum
dummy                    
1      0.036901  0.369012

OR

df.groupby('dummy')['returns'].agg(Mean='mean', Sum='sum')

           Mean       Sum
dummy                    
1      0.036901  0.369012

Pandas >= 0.25: Named Aggregation

Pandas has changed the behavior of GroupBy.agg in favour of a more intuitive syntax for specifying named aggregations. See the 0.25 docs section on Enhancements as well as relevant GitHub issues GH18366 and GH26512.

From the documentation,

To support column-specific aggregation with control over the output column names, pandas accepts the special syntax in GroupBy.agg(), known as “named aggregation”, where

• The keywords are the output column names
• The values are tuples whose first element is the column to select and the second element is the aggregation to apply to that column. Pandas provides the pandas.NamedAgg namedtuple with the fields ['column', 'aggfunc'] to make it clearer what the arguments are. As usual, the aggregation can be a callable or a string alias.

You can now pass a tuple via keyword arguments. The tuples follow the format of (<colName>, <aggFunc>).

import pandas as pd

pd.__version__                                                                                                                            
# '0.25.0.dev0+840.g989f912ee'

# Setup
df = pd.DataFrame({'kind': ['cat', 'dog', 'cat', 'dog'],
                   'height': [9.1, 6.0, 9.5, 34.0],
                   'weight': [7.9, 7.5, 9.9, 198.0]
})

df.groupby('kind').agg(
    max_height=('height', 'max'), min_weight=('weight', 'min'),)

      max_height  min_weight
kind                        
cat          9.5         7.9
dog         34.0         7.5

Alternatively, you can use pd.NamedAgg (essentially a namedtuple) which makes things more explicit.

df.groupby('kind').agg(
    max_height=pd.NamedAgg(column='height', aggfunc='max'), 
    min_weight=pd.NamedAgg(column='weight', aggfunc='min')
)

      max_height  min_weight
kind                        
cat          9.5         7.9
dog         34.0         7.5

It is even simpler for Series, just pass the aggfunc to a keyword argument.

df.groupby('kind')['height'].agg(max_height='max', min_height='min')    

      max_height  min_height
kind                        
cat          9.5         9.1
dog         34.0         6.0       

Lastly, if your column names aren't valid python identifiers, use a dictionary with unpacking:

df.groupby('kind')['height'].agg(**{'max height': 'max', ...})

Pandas < 0.25

In more recent versions of pandas leading upto 0.24, if using a dictionary for specifying column names for the aggregation output, you will get a FutureWarning:

df.groupby('dummy').agg({'returns': {'Mean': 'mean', 'Sum': 'sum'}})
# FutureWarning: using a dict with renaming is deprecated and will be removed 
# in a future version

Using a dictionary for renaming columns is deprecated in v0.20. On more recent versions of pandas, this can be specified more simply by passing a list of tuples. If specifying the functions this way, all functions for that column need to be specified as tuples of (name, function) pairs.

df.groupby("dummy").agg({'returns': [('op1', 'sum'), ('op2', 'mean')]})

        returns          
            op1       op2
dummy                    
1      0.328953  0.032895

Or,

df.groupby("dummy")['returns'].agg([('op1', 'sum'), ('op2', 'mean')])

            op1       op2
dummy                    
1      0.328953  0.032895

$("#id").change(function(){
    //does some stuff;
});

Use

YourCommaSeparatedString.split(',');

In case you have generated-code (EMF, etc.) there can be too many static initialisers which consume all stack space.

See Stack Overflow question How to increase the Java stack size?.

The hide selector was incorrect. I hid the blocks at page load and showed the selected value. I also changed the car div id's to make it easier to append the radio button value and create the proper id selector.

<div id="myRadioGroup">
  2 Cars<input type="radio" name="cars" checked="checked" value="2"  />
  3 Cars<input type="radio" name="cars" value="3" />
  <div id="car-2">
  2 Cars
  </div>
  <div id="car-3">
  3 Cars
  </div>
</div>

<script type="text/javascript">
$(document).ready(function(){ 
  $("div div").hide();
  $("#car-2").show();
  $("input[name$='cars']").click(function() {
      var test = $(this).val();
      $("div div").hide();
      $("#car-"+test).show();
  }); 
});
</script>

Use jquery change event

Description: Bind an event handler to the "change" JavaScript event, or trigger that event on an element.

An example

$("input[type='text']").change( function() {
  // your code
});

The advantage that .change has over .keypress , .focus , .blur is that .change event will fire only when input has changed

for (int i = 0; i < nodeList.getLength(); i++)

change to

for (int i = 0, len = nodeList.getLength(); i < len; i++)

to be more efficient.

The second way of javanna answer may be the best as it tends to use a flatter, predictable memory model.

You can install it using binstar:

conda install -c menpo opencv

svn checkout --force svn://repo website.dir

then

svn revert -R website.dir

Will check out on top of existing files in website.dir, but not overwrite them. Then the revert will overwrite them. This way you do not need to take the site down to complete it.

Yes, see "Loading Page Fragments" on http://api.jquery.com/load/.

In short, you add the selector after the URL. For example:

$('#result').load('ajax/test.html #container');

I did something as below to find patterns in my bucket

def getListOfPrefixesFromS3(dataPath: String, prefix: String, delimiter: String, batchSize: Integer): List[String] = {
    var s3Client = new AmazonS3Client()
    var listObjectsRequest = new ListObjectsRequest().withBucketName(dataPath).withMaxKeys(batchSize).withPrefix(prefix).withDelimiter(delimiter)
    var objectListing: ObjectListing = null
    var res: List[String] = List()

    do {
      objectListing = s3Client.listObjects(listObjectsRequest)
      res = res ++ objectListing.getCommonPrefixes
      listObjectsRequest.setMarker(objectListing.getNextMarker)
    } while (objectListing.isTruncated)
    res
  }

For larger buckets this consumes too much of time since all the object summaries are returned by the Aws and not only the ones that match the prefix and the delimiter. I am looking for ways to improve the performance and so far i've only found that i should name the keys and organise them in buckets properly.

Why don't you try it like this:

$Weddingdate = new DateTime($row2['weddingdate']);
$formattedweddingdate = date_format($Weddingdate, 'd-m-Y');

Or you can also just do it like :

$Weddingdate = new DateTime($row2['weddingdate']);
echo $Weddingdate->format('d-m-Y');

This code shows the example how to prevent entering non digit symbols.

angular.module('app').
  directive('onlyDigits', function () {

    return {
        restrict: 'A',
        require: '?ngModel',
        link: function (scope, element, attrs, modelCtrl) {
            modelCtrl.$parsers.push(function (inputValue) {
                if (inputValue == undefined) return '';
                var transformedInput = inputValue.replace(/[^0-9]/g, '');
                if (transformedInput !== inputValue) {
                    modelCtrl.$setViewValue(transformedInput);
                    modelCtrl.$render();
                }
                return transformedInput;
            });
        }
    };
});

You need change url from https://android.googleapis.com/gcm/send to https://fcm.googleapis.com/fcm/send and change your app library too. this tutorial can help you https://firebase.google.com/docs/cloud-messaging/server#implementing-http-connection-server-protocol

This is how it should be:

Code:

$(function(){
  $("button").mouseover(function(){
    var $p = $("#P44");
    $p.stop()
      .css("background-color","yellow")
      .hide(1500, function() {
          $p.css("background-color","red")
            .show(1500);
      });
  });
});

Demo: http://jsfiddle.net/p7w9W/2/

Explanation:

You have to wait for the callback on the animating functions before you switch background color. You should also not use only numeric ID:s, and if you have an ID of your <p> there you shouldn't include a class in your selector.

I also enhanced your code (caching of the jQuery object, chaining, etc.)

Update: As suggested by VKolev the color is now changing when the item is hidden.

I was also searching same answer, because at some point of time I needed total_count with distinct values along with limit/offset.

Because it's little tricky to do- To get total count with distinct values along with limit/offset. Usually it's hard to get total count with limit/offset. Finally I got the way to do -

SELECT DISTINCT COUNT(*) OVER() as total_count, * FROM table_name limit 2 offset 0;

Query performance is also high.

From the docs, "Note that from + size can not be more than the index.max_result_window index setting which defaults to 10,000". So my admittedly very ad-hoc solution is to just pass size: 10000 or 10,000 minus from if I use the from argument.

Note that following Matt's comment below, the proper way to do this if you have a larger amount of documents is to use the scroll api. I have used this successfully, but only with the python interface.

Don't delete the folder or you will create a registry problem. However, if you do not want to use IIS, search the web for turning it off. You might want to check out "www.blackviper.com" because he lists all Operating System "services" (Not "Computer Services" - both are in Administrator Tools) with extra information for what you can and cannot disable to change to manual. If I recall correctly, he had some IIS info and how to turn it off.

Migrating from Glyphicons to Font Awesome is quite easy.

Include a reference to Font Awesome (either locally, or use the CDN).

<link href="https://maxcdn.bootstrapcdn.com/font-awesome/4.7.0/css/font-awesome.min.css" rel="stylesheet">

Then run a search and replace where you search for glyphicon glyphicon- and replace it with fa fa-, and also change the enclosing element from <span to <i. Most of the CSS class names are the same. Some have changed though, so you have to manually fix those.

Another example : I use it to group Data by date. But some data don't have date. I can group it with the header "NoDate"

Nothing that was written here helped me - but it did set me on the right path. What I ended up doing was the following:

1. Analyze the error message.

   It says Library not found: -lPods-... So it cannot find that particular library. How to resolve it? Well, make sure that this library is in the search path. So where is this library located?

2. Search where the library is located.

   I typed find . | grep -e 'Pods-.*\.a' in a terminal in my ~/Library/Developer/Xcode/DerivedData folder. I found out my libPods-... library is located in a bunch of places, for example ~/Library/Developer/Xcode/DerivedData/[generated-name]/Build/Products/Release-iphonesimulator/libPods-[name].a

3. Add one of these folders to the library search path

   If we add one of these folders to the library search path, then the problem will disappear. However, all the paths have a [generated-name] folder somewhere, in my case [Project]-guyraaahpczkqmhghlwgsdsqyxxs.

   So how do we add that folder to the search path responsibly? By using a build time variable! We can get a list of which variables exist by looking at this answer. It turns out one of the variables that's defined is called ${PODS_CONFIGURATION_BUILD_DIR}, and in that exact folder my libPods-[Product].a is located!

4. Now add that folder to the library search path.

   This is the easy part, and my actual answer to this question. Go to Build Settings -> Search paths -> Library search, make sure it is collapsed, and double click on <Multiple Values>.

   In the dialog that pops up, click on the little '+' sign in the bottom left. Now type "${PODS_CONFIGURATION_BUILD_DIR}", and leave the drop-down option at "non-recursive". Type <Enter>. Now drag this entry all the way back up so that it sits directly under $(inherited).

5. You're done. Rebuild your product!

   My error had now disappeared. Upvote this answer, close the tab, and forget the problem ever existed

Try this

DECLARE @String VARCHAR(100)
SET @String = 'TEST STRING'
SELECT LEFT(@String, LEN(@String) - 1) AS MyTrimmedColumn

Fool proof method (no RegEx and Ctrl+Enter didn't work for me as it was just jumping to next Find):

First, select an occurrence of \n and hit Ctrl+H (brings up the Replace... dialogue, also accessible through Find -> Replace... menu). This populates the Find what field.

Go to the end of any line of your file (press End if your keyboard has it) and select the end of line by holding down Shift and pressing ? (right arrow) EXACTLY once. Then copy-paste this into the Replace with field.

(the animation is for finding true new lines; works the same for replacing them)

For Android problems with this:

in app/src/AndroidManifest.xml change windowSoftInputMode to the following.

<activity
   android:windowSoftInputMode="stateAlwaysHidden|adjustPan">

I had absolutely no problems with this in ios using react-native and keyboardAwareScroll. I was about to implement a ton of code to figure this out until someone gave me this solution. Worked perfectly.

To me, the main gain is that I only need to remember, and read, one form of the complicated regex API syntax - the <compiled_pattern>.method(xxx) form rather than that and the re.func(<pattern>, xxx) form.

The re.compile(<pattern>) is a bit of extra boilerplate, true.

But where regex are concerned, that extra compile step is unlikely to be a big cause of cognitive load. And in fact, on complicated patterns, you might even gain clarity from separating the declaration from whatever regex method you then invoke on it.

I tend to first tune complicated patterns in a website like Regex101, or even in a separate minimal test script, then bring them into my code, so separating the declaration from its use fits my workflow as well.

Never construct BigDecimals from floats or doubles. Construct them from ints or strings. floats and doubles loose precision.

This code works as expected (I just changed the type from double to String):

public static void main(String[] args) {
  String doubleVal = "1.745";
  String doubleVal1 = "0.745";
  BigDecimal bdTest = new BigDecimal(  doubleVal);
  BigDecimal bdTest1 = new BigDecimal(  doubleVal1 );
  bdTest = bdTest.setScale(2, BigDecimal.ROUND_HALF_UP);
  bdTest1 = bdTest1.setScale(2, BigDecimal.ROUND_HALF_UP);
  System.out.println("bdTest:"+bdTest); //1.75
  System.out.println("bdTest1:"+bdTest1);//0.75, no problem
}

In the command prompt, type the command below and press Enter.

bcdedit /enum

Under the Windows Boot Loader sections, make note of the identifier value.

To start in safe mode from command prompt :

bcdedit /set {identifier} safeboot minimal 

Then enter the command line to reboot your computer.

I assume 0 means false (which is the case in a lot of programming languages). That means true is not 0 (some languages use -1 some others use 1; doesn't hurt to be compatible to either). So assuming by "better" you mean less typing, you can just write:

bool boolValue = intValue != 0;

You can set the value of document.location.href for this purpose. It points to the current URL. jQuery is not required to do this.

You can always use the 'pre' tag inside the label, and just enter the blank spaces in it, So you can always add the same or different number of spaces you require

<form>
<label>First Name :<pre>Here just enter number of spaces you want to use(I mean using spacebar to enter blank spaces)</pre>
<input type="text"></label>
<label>Last Name :<pre>Now Enter enter number of spaces to match above number of 
spaces</pre>
<input type="text"></label>
</form>

Hope you like my answer, It's a simple and efficient hack

It's called a "finalizer", and you should usually only create one for a class whose state (i.e.: fields) include unmanaged resources (i.e.: pointers to handles retrieved via p/invoke calls). However, in .NET 2.0 and later, there's actually a better way to deal with clean-up of unmanaged resources: SafeHandle. Given this, you should pretty much never need to write a finalizer again.

We can add scroll bar even without using Canvas. I have read it in many other post we can't add vertical scroll bar in frame directly etc etc. But after doing many experiment found out way to add vertical as well as horizontal scroll bar :). Please find below code which is used to create scroll bar in treeView and frame.

f = Tkinter.Frame(self.master,width=3)
f.grid(row=2, column=0, columnspan=8, rowspan=10, pady=30, padx=30)
f.config(width=5)
self.tree = ttk.Treeview(f, selectmode="extended")
scbHDirSel =tk.Scrollbar(f, orient=Tkinter.HORIZONTAL, command=self.tree.xview)
scbVDirSel =tk.Scrollbar(f, orient=Tkinter.VERTICAL, command=self.tree.yview)
self.tree.configure(yscrollcommand=scbVDirSel.set, xscrollcommand=scbHDirSel.set)           
self.tree["columns"] = (self.columnListOutput)
self.tree.column("#0", width=40)
self.tree.heading("#0", text='SrNo', anchor='w')
self.tree.grid(row=2, column=0, sticky=Tkinter.NSEW,in_=f, columnspan=10, rowspan=10)
scbVDirSel.grid(row=2, column=10, rowspan=10, sticky=Tkinter.NS, in_=f)
scbHDirSel.grid(row=14, column=0, rowspan=2, sticky=Tkinter.EW,in_=f)
f.rowconfigure(0, weight=1)
f.columnconfigure(0, weight=1)

Using Date object guarantees that. For eg if you try to create April 31st :

new Date(2014,3,31)        // Thu May 01 2014 00:00:00

Please note that it's zero indexed, so Jan. is 0, Feb. is 1 etc.

Yes, you can input multiple items from cin, using exactly the syntax you describe. The result is essentially identical to:

cin >> a;
cin >> b;
cin >> c;

This is due to a technique called "operator chaining".

Each call to operator>>(istream&, T) (where T is some arbitrary type) returns a reference to its first argument. So cin >> a returns cin, which can be used as (cin>>a)>>b and so forth.

Note that each call to operator>>(istream&, T) first consumes all whitespace characters, then as many characters as is required to satisfy the input operation, up to (but not including) the first next whitespace character, invalid character, or EOF.

We have been using the plugin bootstrap-select for Bootstrap for dtyling selects. Really works well and has lots of interesting additional features. I can recommend it for sure.

Just specify max-width: 100% alone, that should do it.

?? should be preferred to || because it checks only for nulls and undefined.

All The expressions below are true:

(null || 'x') === 'x' ;
(undefined || 'x') === 'x' ;
//Most of the times you don't want the result below
('' || 'x') === 'x'  ;
(0 || 'x') === 'x' ;
(false || 'x') === 'x' ;
//-----

//Using ?? is preferred
(null ?? 'x') === 'x' ;
(undefined ?? 'x') === 'x' ;
//?? works only for null and undefined, which is in general safer
('' ?? 'x') === '' ;
(0 ?? 'x') === 0 ;
(false ?? 'x') === false ;

Bottom line:

int j=i ?? 10; is perfectly fine to use in javascript also. Just replace int with let.

Asterisk: Check browser compatibility and if you really need to support these other browsers use babel.

This is known as a fork bomb. It keeps splitting itself until there is no option but to restart the system. http://en.wikipedia.org/wiki/Fork_bomb

Quit skype and right click on wamp icon-apache-services-start all services that will work after wamp server is start you can use skype again ;)

You can do this by using the following xml

<RelativeLayout
    style="@style/GenericProgressBackground"
    android:id="@+id/loadingPanel"
    >
    <ProgressBar
        style="@style/GenericProgressIndicator"/>
</RelativeLayout>

With this style

<style name="GenericProgressBackground" parent="android:Theme">
    <item name="android:layout_width">fill_parent</item>    
    <item name="android:layout_height">fill_parent</item>
    <item name="android:background">#DD111111</item>    
    <item name="android:gravity">center</item>  
</style>
<style name="GenericProgressIndicator" parent="@android:style/Widget.ProgressBar.Small">
    <item name="android:layout_width">wrap_content</item>
    <item name="android:layout_height">wrap_content</item>
    <item name="android:indeterminate">true</item> 
</style>

To use this, you must hide your UI elements by setting the visibility value to GONE and whenever the data is loaded, call setVisibility(View.VISIBLE) on all your views to restore them. Don't forget to call findViewById(R.id.loadingPanel).setVisiblity(View.GONE) to hide the loading animation.

If you dont have a loading event/function but just want the loading panel to disappear after x seconds use a Handle to trigger the hiding/showing.

There were several problems in your code. Here you have a functional version you can analyze (Lets set 'hello' as the target word):

word = 'hello'
so_far = "-" * len(word)       # Create variable so_far to contain the current guess

while word != so_far:          # if still not complete
    print(so_far)
    guess = input('>> ')       # get a char guess

    if guess in word:
        print("\nYes!", guess, "is in the word!")

        new = ""
        for i in range(len(word)):  
            if guess == word[i]:
                new += guess        # fill the position with new value
            else:
                new += so_far[i]    # same value as before
        so_far = new
    else:
        print("try_again")

print('finish')

I tried to write it for py3k with a py2k ide, be careful with errors.

i found something in the browser side itself.

Try this steps. here i have been mentioned the Steps to disable the Header and footer in all the three major browsers.

Chrome Click the Menu icon in the top right corner of the browser. Click Print. Uncheck Headers and Footers under the Options section.

Firefox Click Firefox in the top left corner of the browser. Place your mouse over Print, the click Page Setup. Click the Margins & Header/Footer tab. Change each value under Headers & Footers to --blank--.

Internet Explorer Click the Gear icon in the top right corner of the browser. Place your mouse over Print, then click Page Setup. Change each value under Headers and Footers to -Empty-.

postgresql.conf is located in PostgreSQL's data directory. The data directory is configured during the setup and the setting is saved as PGDATA entry in c:\Program Files\PostgreSQL\<version>\pg_env.bat, for example

@ECHO OFF
REM The script sets environment variables helpful for PostgreSQL

@SET PATH="C:\Program Files\PostgreSQL\<version>\bin";%PATH%
@SET PGDATA=D:\PostgreSQL\<version>\data
@SET PGDATABASE=postgres
@SET PGUSER=postgres
@SET PGPORT=5432
@SET PGLOCALEDIR=C:\Program Files\PostgreSQL\<version>\share\locale

Alternatively you can query your database with SHOW config_file; if you are a superuser.

I'm not sure there is an api to get the default system font name. So I just get the name like this :

    //get system default font
    UILabel *label = [[UILabel alloc] init];        
    fontname = label.font.fontName;
    [label release];

Looks stupid but it works.

Don't store it if possible. Just read through it if you are memory constrained. You can use a StreamReader:

using (var reader = new StreamReader("file.txt"))
{
    var line = reader.ReadLine();
    // process line here
}

This can be wrapped in a method which yields strings per line read if you want to use LINQ.

Warning: this answer covers only ReactRouter versions before 1.0

I will update this answer with 1.0.0-rc1 use cases after!

You can do this without mixins too.

let Authentication = React.createClass({
  contextTypes: {
    router: React.PropTypes.func
  },
  handleClick(e) {
    e.preventDefault();
    this.context.router.transitionTo('/');
  },
  render(){
    return (<div onClick={this.handleClick}>Click me!</div>);
  }
});

The gotcha with contexts is that it is not accessible unless you define the contextTypes on the class.

As for what is context, it is an object, like props, that are passed down from parent to child, but it is passed down implicitly, without having to redeclare props each time. See https://www.tildedave.com/2014/11/15/introduction-to-contexts-in-react-js.html

Advantages

• By inlining your code where it is needed, your program will spend less time in the function call and return parts. It is supposed to make your code go faster, even as it goes larger (see below). Inlining trivial accessors could be an example of effective inlining.
• By marking it as inline, you can put a function definition in a header file (i.e. it can be included in multiple compilation unit, without the linker complaining)

Disadvantages

• It can make your code larger (i.e. if you use inline for non-trivial functions). As such, it could provoke paging and defeat optimizations from the compiler.
• It slightly breaks your encapsulation because it exposes the internal of your object processing (but then, every "private" member would, too). This means you must not use inlining in a PImpl pattern.
• It slightly breaks your encapsulation 2: C++ inlining is resolved at compile time. Which means that should you change the code of the inlined function, you would need to recompile all the code using it to be sure it will be updated (for the same reason, I avoid default values for function parameters)
• When used in a header, it makes your header file larger, and thus, will dilute interesting informations (like the list of a class methods) with code the user don't care about (this is the reason that I declare inlined functions inside a class, but will define it in an header after the class body, and never inside the class body).

Inlining Magic

• The compiler may or may not inline the functions you marked as inline; it may also decide to inline functions not marked as inline at compilation or linking time.
• Inline works like a copy/paste controlled by the compiler, which is quite different from a pre-processor macro: The macro will be forcibly inlined, will pollute all the namespaces and code, won't be easily debuggable, and will be done even if the compiler would have ruled it as inefficient.
• Every method of a class defined inside the body of the class itself is considered as "inlined" (even if the compiler can still decide to not inline it
• Virtual methods are not supposed to be inlinable. Still, sometimes, when the compiler can know for sure the type of the object (i.e. the object was declared and constructed inside the same function body), even a virtual function will be inlined because the compiler knows exactly the type of the object.
• Template methods/functions are not always inlined (their presence in an header will not make them automatically inline).
• The next step after "inline" is template metaprograming . I.e. By "inlining" your code at compile time, sometimes, the compiler can deduce the final result of a function... So a complex algorithm can sometimes be reduced to a kind of return 42 ; statement. This is for me extreme inlining. It happens rarely in real life, it makes compilation time longer, will not bloat your code, and will make your code faster. But like the grail, don't try to apply it everywhere because most processing cannot be resolved this way... Still, this is cool anyway...
  :-p

You cannot directly create a table stored as a sequence file and insert text into it. You must do this:

1. Create a table stored as text
2. Insert the text file into the text table
3. Do a CTAS to create the table stored as a sequence file.
4. Drop the text table if desired

Example:

CREATE TABLE test_txt(field1 int, field2 string)
ROW FORMAT DELIMITED FIELDS TERMINATED BY '\t';

LOAD DATA INPATH '/path/to/file.tsv' INTO TABLE test_txt;

CREATE TABLE test STORED AS SEQUENCEFILE
AS SELECT * FROM test_txt;

DROP TABLE test_txt;

I'm not entirely sure but I think you are probably surprised at how arrays are serialized in JSON. Let's isolate the problem. Consider following code:

var display = Array();
display[0] = "none";
display[1] = "block";
display[2] = "none";

console.log( JSON.stringify(display) );

This will print:

["none","block","none"]

This is how JSON actually serializes array. However what you want to see is something like:

{"0":"none","1":"block","2":"none"}

To get this format you want to serialize object, not array. So let's rewrite above code like this:

var display2 = {};
display2["0"] = "none";
display2["1"] = "block";
display2["2"] = "none";

console.log( JSON.stringify(display2) );

This will print in the format you want.

You can play around with this here: http://jsbin.com/oDuhINAG/1/edit?js,console

Try this code in Swift or Objective-C

Swift

self.tabBarController.selectedIndex = 1

Objective-C

[self.tabBarController setSelectedIndex:1];

Yeah, this is a general generics problem, not mockito-specific.

There is no class object for ArrayList<SomeType>, and thus you can't type-safely pass such an object to a method requiring a Class<ArrayList<SomeType>>.

You can cast the object to the right type:

Class<ArrayList<SomeType>> listClass =
              (Class<ArrayList<SomeType>>)(Class)ArrayList.class;
ArgumentCaptor<ArrayList<SomeType>> argument = ArgumentCaptor.forClass(listClass);

This will give some warnings about unsafe casts, and of course your ArgumentCaptor can't really differentiate between ArrayList<SomeType> and ArrayList<AnotherType> without maybe inspecting the elements.

(As mentioned in the other answer, while this is a general generics problem, there is a Mockito-specific solution for the type-safety problem with the @Captor annotation. It still can't distinguish between an ArrayList<SomeType> and an ArrayList<OtherType>.)

Edit:

Take also a look at tenshis comment. You can change the original code from Paulo Ebermann to this (much simpler)

final ArgumentCaptor<List<SomeType>> listCaptor
        = ArgumentCaptor.forClass((Class) List.class);

Search for make.exe using the search feature, when found, note down the absolute path to the file. You can do that by right-clicking on the filename in the search result and then properties, or open location folder (not sure of the exact wording, I'm not using an English locale).

When you open the command line console (cmd) instead of typing make, type the whole path and name, e.g. C:\Windows\System32\java (this is for java...).

Alternatively, if you don't want to provide the full path each time, then you have to possibilities:

• make C:\Windows\System32\ the current working directory, using cd at cmd level.
• add C:\Windows\System32\ to you PATH environment variable.

Refs:

• use full path: http://technet.microsoft.com/en-us/magazine/ff678296.aspx
• cd: http://technet.microsoft.com/en-us/library/cc731237.aspx
• PATH: http://technet.microsoft.com/en-us/library/bb490963.aspx

You must return something

instead of this (this is not the right way)

const def = (props) => { <div></div> };

try

const def = (props) => ( <div></div> );

or use return statement

const def = (props) => { return  <div></div> };

sed 's/^.\{5\}//' logfile 

and you replace 5 by the number you want...it should do the trick...

EDIT if for each line sed 's/^.\{5\}//g' logfile

Use -B, -A or -C option

grep --help
...
-B, --before-context=NUM  print NUM lines of leading context
-A, --after-context=NUM   print NUM lines of trailing context
-C, --context=NUM         print NUM lines of output context
-NUM                      same as --context=NUM
...

The way you have used the HTML syntax is problematic.

This is how the syntax should be

style="property1:value1;property2:value2"

In your case, this will be the way to do

<h2 style="text-align :center; font-family :tahoma" >TITLE</h2>

A further example would be as follows

<div class ="row">
    <button type="button" style= "margin-top : 20px; border-radius: 15px" 
    class="btn btn-primary">View Full Profile</button>
</div>

This is the first example in the manual page for mysql_query:

$result = mysql_query('SELECT * WHERE 1=1');
if (!$result) {
    die('Invalid query: ' . mysql_error());
}

If you wish to use something other than die, then I'd suggest trigger_error.

Strictly with sed:

grep ... | sed -e 's/^\(.\{N\}\).*$/\1/'

Sorry, I wasn't sure which SQL platform you're talking about:

In MySQL:

$query = ("SELECT * FROM $db WHERE conditions AND LENGTH(col_name) = 3");

in MSSQL

$query = ("SELECT * FROM $db WHERE conditions AND LEN(col_name) = 3");

The LENGTH() (MySQL) or LEN() (MSSQL) function will return the length of a string in a column that you can use as a condition in your WHERE clause.

Edit

I know this is really old but thought I'd expand my answer because, as Paulo Bueno rightly pointed out, you're most likely wanting the number of characters as opposed to the number of bytes. Thanks Paulo.

So, for MySQL there's the CHAR_LENGTH(). The following example highlights the difference between LENGTH() an CHAR_LENGTH():

CREATE TABLE words (
    word VARCHAR(100)
) ENGINE INNODB DEFAULT CHARSET utf8mb4 COLLATE utf8mb4_unicode_ci;

INSERT INTO words(word) VALUES('??'), ('happy'), ('hayir');

SELECT word, LENGTH(word) as num_bytes, CHAR_LENGTH(word) AS num_characters FROM words;

+--------+-----------+----------------+
| word   | num_bytes | num_characters |
+--------+-----------+----------------+
| ??    |         6 |              2 |
| happy  |         5 |              5 |
| hayir  |         6 |              5 |
+--------+-----------+----------------+

Be careful if you're dealing with multi-byte characters.

Virtualenv is a tool to create isolated Python environments.

Let's say you're working in 2 different projects, A and B. Project A is a web project and the team is using the following packages:

• Python 2.8.x
• Django 1.6.x

The project B is also a web project but your team is using:

• Python 2.7.x
• Django 1.4.x

The machine that you're working doesn't have any version of django, what should you do? Install django 1.4? django 1.6? If you install django 1.4 globally would be easy to point to django 1.6 to work in project A?

Virtualenv is your solution! You can create 2 different virtualenv's, one for project A and another for project B. Now, when you need to work in project A, just activate the virtualenv for project A, and vice-versa.

A better tip when using virtualenv is to install virtualenvwrapper to manage all the virtualenv's that you have, easily. It's a wrapper for creating, working, removing virtualenv's.

int max = 50;
int min = 1;

1. Using Math.random()

double random = Math.random() * 49 + 1;
or
int random = (int )(Math.random() * 50 + 1);

This will give you value from 1 to 50 in case of int or 1.0 (inclusive) to 50.0 (exclusive) in case of double

Why?

random() method returns a random number between 0.0 and 0.9..., you multiply it by 50, so upper limit becomes 0.0 to 49.999... when you add 1, it becomes 1.0 to 50.999..., now when you truncate to int, you get 1 to 50. (thanks to @rup in comments). leepoint's awesome write-up on both the approaches.

2. Using Random class in Java.

Random rand = new Random(); 
int value = rand.nextInt(50); 

This will give value from 0 to 49.

For 1 to 50: rand.nextInt((max - min) + 1) + min;

Source of some Java Random awesomeness.

The previous answer is correct but I'll give you all the code as well.

Your app.config should look like this:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
   <configSections>
      <section name="ServicesSection" type="RT.Core.Config.ServiceConfigurationSection, RT.Core"/>
   </configSections>
   <ServicesSection>
      <Services>
         <add Port="6996" ReportType="File" />
         <add Port="7001" ReportType="Other" />
      </Services>
   </ServicesSection>
</configuration>

Your ServiceConfig and ServiceCollection classes remain unchanged.

You need a new class:

public class ServiceConfigurationSection : ConfigurationSection
{
   [ConfigurationProperty("Services", IsDefaultCollection = false)]
   [ConfigurationCollection(typeof(ServiceCollection),
       AddItemName = "add",
       ClearItemsName = "clear",
       RemoveItemName = "remove")]
   public ServiceCollection Services
   {
      get
      {
         return (ServiceCollection)base["Services"];
      }
   }
}

And that should do the trick. To consume it you can use:

ServiceConfigurationSection serviceConfigSection =
   ConfigurationManager.GetSection("ServicesSection") as ServiceConfigurationSection;

ServiceConfig serviceConfig = serviceConfigSection.Services[0];

In my case, i was facing this issue while installing create-react-app in MAC (Mojave OS) with following command :

I have read npm.community that try to install without sudo :

npm install create-react-app -g

and it actually solved my issue ..!!

I was running into the same problem, here is how I got it working..

open terminal:

mkdir testExpress
cd testExpress
npm install request

or

sudo npm install -g request // If you would like to globally install.

now don't use

node app.js or node test.js, you will run into this problem doing so. You can also print the problem that is being cause by using this command.. "node -p app.js"

The above command to start nodeJs has been deprecated. Instead use

npm start

You should see this..

[email protected] start /Users/{username}/testExpress
node ./bin/www

Open your web browser and check for localhost:3000

You should see Express install (Welcome to Express)

df.groupby('Company Name').agg({'Organisation name':'count','Amount':'sum'})\
    .apply(lambda x: x.sort_values(['count','sum'], ascending=False))

You can perform a simple each loop on the range from 1 to `x´:

(1..x).each do |i|
  #...
end

just insert this jquery code to your HTML's head section:

<!--[if lt IE 9 ]>
     <script>
        $(document).ready(function(){
            $('a > button').click(function(){
                window.location.href = $(this).parent().attr('href');
            });
        });
    </script>
<![endif]-->

    client.post(getUrl(), params,

        new AsyncHttpResponseHandler() {

            public void onSuccess(String result) {

                Log.d(TAG,"uploadFile response: "+result);

            };

}

A string to char array is as simple as

String str = "someString"; 
char[] charArray = str.toCharArray();

Can you explain a little more on what you are trying to do?

* Update *

if I am understanding your new comment, you can use a byte array and example is provided.

byte[] bytes = ByteBuffer.allocate(4).putInt(1695609641).array();

for (byte b : bytes) {
   System.out.format("0x%x ", b);
}

With the following output

0x65 0x10 0xf3 0x29

Have you taken a look at ExpandoObject?

see: http://blogs.msdn.com/b/csharpfaq/archive/2009/10/01/dynamic-in-c-4-0-introducing-the-expandoobject.aspx

From MSDN:

The ExpandoObject class enables you to add and delete members of its instances at run time and also to set and get values of these members. This class supports dynamic binding, which enables you to use standard syntax like sampleObject.sampleMember instead of more complex syntax like sampleObject.GetAttribute("sampleMember").

Allowing you to do cool things like:

dynamic dynObject = new ExpandoObject();
dynObject.SomeDynamicProperty = "Hello!";
dynObject.SomeDynamicAction = (msg) =>
    {
        Console.WriteLine(msg);
    };

dynObject.SomeDynamicAction(dynObject.SomeDynamicProperty);

Based on your actual code you may be more interested in:

public static dynamic GetDynamicObject(Dictionary<string, object> properties)
{
    return new MyDynObject(properties);
}

public sealed class MyDynObject : DynamicObject
{
    private readonly Dictionary<string, object> _properties;

    public MyDynObject(Dictionary<string, object> properties)
    {
        _properties = properties;
    }

    public override IEnumerable<string> GetDynamicMemberNames()
    {
        return _properties.Keys;
    }

    public override bool TryGetMember(GetMemberBinder binder, out object result)
    {
        if (_properties.ContainsKey(binder.Name))
        {
            result = _properties[binder.Name];
            return true;
        }
        else
        {
            result = null;
            return false;
        }
    }

    public override bool TrySetMember(SetMemberBinder binder, object value)
    {
        if (_properties.ContainsKey(binder.Name))
        {
            _properties[binder.Name] = value;
            return true;
        }
        else
        {
            return false;
        }
    }
}

That way you just need:

var dyn = GetDynamicObject(new Dictionary<string, object>()
    {
        {"prop1", 12},
    });

Console.WriteLine(dyn.prop1);
dyn.prop1 = 150;

Deriving from DynamicObject allows you to come up with your own strategy for handling these dynamic member requests, beware there be monsters here: the compiler will not be able to verify a lot of your dynamic calls and you won't get intellisense, so just keep that in mind.

The linefeed character \n is not the line separator in certain operating systems (such as windows, where it's "\r\n") - my suggestion is that you use \r\n instead, then it'll both see the line-break with only \n and \r\n, I've never had any problems using it.

Also, you should look into using a StringBuilder instead of concatenating the String in the while-loop at BookCatalog.toString(), it is a lot more effective. For instance:

public String toString() {
        BookNode current = front;
        StringBuilder sb = new StringBuilder();
        while (current!=null){
            sb.append(current.getData().toString()+"\r\n ");
            current = current.getNext();
        }
        return sb.toString();
}

Use the Controller's Redirect() method.

public ActionResult YourAction()
{
    // ...
    return Redirect("http://www.example.com");
}

Update

You can't directly perform a server side redirect from an ajax response. You could, however, return a JsonResult with the new url and perform the redirect with javascript.

public ActionResult YourAction()
{
    // ...
    return Json(new {url = "http://www.example.com"});
}

$.post("@Url.Action("YourAction")", function(data) {
    window.location = data.url;
});

Try opening services.msc from the start menu search box and try manually starting the MySQL service or directly write services.msc in Run box

raw.githubusercontent.com/username/repo-name/branch-name/path

Replace username with the username of the user that created the repo.

Replace repo-name with the name of the repo.

Replace branch-name with the name of the branch.

Replace path with the path to the file.

To reverse to go to GitHub.com:

GitHub.com/username/repo-name/directory-path/blob/branch-name/filename

/// Create the bottom sheet UI
  Widget bottomSheetBuilder(){
    return Container(
      color: Color(0xFF737373), // This line set the transparent background
      child: Container(
        decoration: BoxDecoration(
          color: Colors.white,
            borderRadius: BorderRadius.only(
                topLeft: Radius.circular(16.0),
                topRight: Radius.circular( 16.0)
            )
        ),
        child: Center( child: Text("Hi everyone!"),)
      ),
    );
  }

Call this to show the BotoomSheet with corners:

/// Show the bottomSheet when called
  Future _onMenuPressed() async {
    showModalBottomSheet(
        context: context,
        builder: (widgetBuilder) => bottomSheetBuilder()
    );
  }

Index the list then the dict.

print L[1]['d']

ANSI (aka Windows-1252/WinLatin1) is a character encoding of the Latin alphabet, fairly similar to ISO-8859-1. You may want to take a look of it at Wikipedia.

this.$("#yourSelector").select2("data", { id: 1, text: "Some Text" });

this should be of help.

Writing the code for checking palindromes following the best practices of JavaScript:

I had similar experience and it took me time to solve the problem. Though, my own case was ASP.Net MVC Core and Core framework. Setting Trusted_Connection=False; solved my problem.

Inside appsettings.json file

"ConnectionStrings": {
    "DefaultConnection": "Server=servername; Database=databasename; User Id=userid; Password=password; Trusted_Connection=False; MultipleActiveResultSets=true",
  },

public class ScannerExample {

        int a;
        String s;
        Scanner scan = new Scanner(System.in);

        System.out.println("enter a no");
        a = scan.nextInt();
        System.out.println("no is =" + a);

        System.out.println("enter a string");
        s = scan.next();
        System.out.println("string is=" + s);
    }
}

I would try this:

select sum (case when TotalHousM is null then 0 else TotalHousM end)
       + (case when TotalHousT is null then 0 else TotalHousT end)
       + (case when TotalHousW is null then 0 else TotalHousW end)
       + (case when TotalHousTH is null then 0 else TotalHousTH end)
       + (case when TotalHousF is null then 0 else TotalHousF end)
       as Total

I was just working on this within MaterialUI's text inputs. Adding padding-top: 0.5rem to the input style worked for me. While this was adjusting the padding, at least you don't need to worry about adjusting for updates, much less different breakpoints.

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

This is probably too late, but I had a similar problem with dates that I wanted entered into cells from a text variable. Inevitably, it converted my variable text value to a date. What I finally had to do was concatentate a ' to the string variable and then put it in the cell like this:

prvt_rng_WrkSht.Cells(prvt_rng_WrkSht.Rows.Count, cnst_int_Col_Start_Date).Formula = "'" & _ 
    param_cls_shift.Start_Date (string property of my class) 

This is because IIS 7 uses http handlers from both <system.web><httpHandlers> and <system.webServer><handlers>. if you need CloudConnectHandler in your application, you should add <httpHandlers> section with this handler to the <system.web>:

<httpHandlers>
    <add verb="*" path="CloudConnect.aspx" type="CloudConnectHandler" />
</httpHandlers>

and also add preCondition attribute to the handler in <system.webServer>:

<handlers>
  <add name="CloudConnectHandler" verb="*" path="CloudConnect.aspx" type="CloudConnectHandler" preCondition="integratedMode" />
</handlers>

Hope it helps

Fix: sudo mongod

I had the same problem, running mongod with sudo privileges fixed it. Coming from a windows environment, I used just mongod to start the daemon, well it looks like we need the superuser privileges to access /data/db.

You can also give non root users Read and Write permissions to that path. check answers above for a guide!

Since you tagged Java-ee as well - then YES it is possible.

and in core java as well it is possible using static blocks

and check this How can you run a Java program without main method?

Edit:
as already pointed out in other answers - it does not support from Java 7

From your question all I can understand is that you already have some hover effect on your button which you want remove. For that either remove that css which causes the hover effect or override it.

For overriding, do this

.buttonDisabled:hover
{
    //overriding css goes here
}

For example if your button's background color changes on hover from red to blue. In the overriding css you will make it as red so that it doesnt change.

Also go through all the rules of writing and overriding css. Get familiar with what css will have what priority.

Best of luck.

You can read up elsewhere on substitution variables; they're quite handy in SQL Developer. But I have fits trying to use bind variables in SQL Developer. This is what I do:

SET SERVEROUTPUT ON
declare
  v_testnum number;
  v_teststring varchar2(1000);

begin
   v_testnum := 2;
   DBMS_OUTPUT.put_line('v_testnum is now ' || v_testnum);

   SELECT 36,'hello world'
   INTO v_testnum, v_teststring
   from dual;

   DBMS_OUTPUT.put_line('v_testnum is now ' || v_testnum);
   DBMS_OUTPUT.put_line('v_teststring is ' || v_teststring);
end;

SET SERVEROUTPUT ON makes it so text can be printed to the script output console.

I believe what we're doing here is officially called PL/SQL. We have left the pure SQL land and are using a different engine in Oracle. You see the SELECT above? In PL/SQL you always have to SELECT ... INTO either variable or a refcursor. You can't just SELECT and return a result set in PL/SQL.

If you’re using TortoiseSVN…

From your commit window in the “Changes Made” section you can select all the offending files, then right-click and select delete. Finish the commit and the files will be removed from the scheduled additions.

You can use the built-in encryption of the sqlite .net provider (System.Data.SQLite). See more details at http://web.archive.org/web/20070813071554/http://sqlite.phxsoftware.com/forums/t/130.aspx

To encrypt an existing unencrypted database, or to change the password of an encrypted database, open the database and then use the ChangePassword() function of SQLiteConnection:

// Opens an unencrypted database
SQLiteConnection cnn = new SQLiteConnection("Data Source=c:\\test.db3");
cnn.Open();
// Encrypts the database. The connection remains valid and usable afterwards.
cnn.ChangePassword("mypassword");

To decrypt an existing encrypted database call ChangePassword() with a NULL or "" password:

// Opens an encrypted database
SQLiteConnection cnn = new SQLiteConnection("Data Source=c:\\test.db3;Password=mypassword");
cnn.Open();
// Removes the encryption on an encrypted database.
cnn.ChangePassword(null);

To open an existing encrypted database, or to create a new encrypted database, specify a password in the ConnectionString as shown in the previous example, or call the SetPassword() function before opening a new SQLiteConnection. Passwords specified in the ConnectionString must be cleartext, but passwords supplied in the SetPassword() function may be binary byte arrays.

// Opens an encrypted database by calling SetPassword()
SQLiteConnection cnn = new SQLiteConnection("Data Source=c:\\test.db3");
cnn.SetPassword(new byte[] { 0xFF, 0xEE, 0xDD, 0x10, 0x20, 0x30 });
cnn.Open();
// The connection is now usable

By default, the ATTACH keyword will use the same encryption key as the main database when attaching another database file to an existing connection. To change this behavior, you use the KEY modifier as follows:

If you are attaching an encrypted database using a cleartext password:

// Attach to a database using a different key than the main database
SQLiteConnection cnn = new SQLiteConnection("Data Source=c:\\test.db3");
cnn.Open();
cmd = new SQLiteCommand("ATTACH DATABASE 'c:\\pwd.db3' AS [Protected] KEY 'mypassword'", cnn);
cmd.ExecuteNonQuery();

To attach an encrypted database using a binary password:

// Attach to a database encrypted with a binary key
SQLiteConnection cnn = new SQLiteConnection("Data Source=c:\\test.db3");
cnn.Open();
cmd = new SQLiteCommand("ATTACH DATABASE 'c:\\pwd.db3' AS [Protected] KEY X'FFEEDD102030'", cnn);
cmd.ExecuteNonQuery();

<service android:name=".Service2"
            android:process="@string/app_name"
            android:exported="true"
            android:isolatedProcess="true"
            />

Declare this in your manifest. Give a custom name to your process and make that process isolated and exported .

You can try:

{{ 1 * num_str + 1 }}

http://jsfiddle.net/Z32fP/

var data= { 
    myAction: function(array){
        return array.filter(function(el){
           return (el !== (undefined || null || ''));
        }).join(" ");
    }
}; 
var string = data.myAction(["I", "am","", "working", "", "on","", "nodejs", "" ]);
console.log(string);

Output:

I am working on nodejs

It will remove empty element from array and display other element.

You don't need to rely on the preprocessor to ensure your enums and strings are in sync. To me using macros tend to make the code harder to read.

Using Enum And An Array Of Strings

enum fruit                                                                   
{
    APPLE = 0, 
    ORANGE, 
    GRAPE,
    BANANA,
    /* etc. */
    FRUIT_MAX                                                                                                                
};   

const char * const fruit_str[] =
{
    [BANANA] = "banana",
    [ORANGE] = "orange",
    [GRAPE]  = "grape",
    [APPLE]  = "apple",
    /* etc. */  
};

Note: the strings in the fruit_str array don't have to be declared in the same order as the enum items.

How To Use It

printf("enum apple as a string: %s\n", fruit_str[APPLE]);

Adding A Compile Time Check

If you are afraid to forget one string, you can add the following check:

#define ASSERT_ENUM_TO_STR(sarray, max) \                                       
  typedef char assert_sizeof_##max[(sizeof(sarray)/sizeof(sarray[0]) == (max)) ? 1 : -1]

ASSERT_ENUM_TO_STR(fruit_str, FRUIT_MAX);

An error would be reported at compile time if the amount of enum items does not match the amount of strings in the array.

I also faced this same issue while working in my development environment, the problem was that I left host: localhost commented out in the config/database.yml file.

So my application could not connect to the PostgreSQL database, simply uncommenting it solved the issue.

development:
  <<: *default
  database: database_name

  username: database_username 

  password: database_password

  host: localhost

That's all.

I hope this helps

You could try the somewhat dangerous: taskkill /IM cmd.exe ..dangerous bcz that will kill the cmd that is open and any cmd's opened before it.

Or add a verification to confirm that you had the right cmd.exe and then kill it via PID, such as this:

set loc=%time%%random%
title=%loc%
for /f "tokens=2 delims= " %%A in ('tasklist /v ^| findstr /i "%loc%"') do (taskkill /PID %%A) 

Substitute (pslist &&A) or (tasklist /FI "PID eq %%A") for the (taskkill /PID %%A) if you want to check it first (and maybe have pstools installed).

1. Select all cells by left-top corner
2. Choose [Home] >> [Conditional Formatting] >> [New Rule]
3. Choose [Format only cells that contain]
4. In [Format only cells with:], choose "Errors"
5. Choose proper formats in [Format..] button

You can add ng-change directive to input fields. Have a look at the docs example.

Do this in your .profile -

export JAVA_HOME=`/usr/libexec/java_home`

(backticks make sure to execute the command and place its value in JAVA_HOME)

Mostly the default shortcut key combination is Ctrl + Alt + Left/Right. (I'm using the linux version)

Or you can have a toolbar option for it. Enable the tool bar by View -> Toolbar. The Left and Right Arrows will do the same. If you hover over it then you can see the shortcut key combination also.

Just in case the key combination is not working (this can be due to several reasons like you are using a virtual machine, etc) you can change this default key combination, or you can add an extra combination (ex: For Back/Move to previous Ctrl + Alt + < or Comma).

Go to Settings -> select keymap (type keymap in the search bar) -> **Editor Actions -> search for back and find Navigate options -> change the settings as you prefer.

I Was trying to do the exact same thing, I accomplished this after a long time! Here is the code I ended up using! It works: Perfect! This was Done by using the shortcuts.js library! added a few other key presses as an example!

Just Run the code snip-it, Click inside box and press the G key!

Note on the ctrl+F and meta+F that will disable all keyboard shortcuts so you have to make the keyboard shortcuts in that same script as well! also the keyboard shortcut actions can only be called in javascript!

For security reasons, you can't move the mouse pointer with javascript, nor simulate a click with it.

What is it that you are trying to accomplish?

As for cv2 is concerned.

1. You might not have provided the right file type while cv2.imread(). eg jpg instead of png.
2. Or you are providing image path instead of image's array. eg plt.imshow(img_path),

try cv2.imread(img_path) first then plt.imshow(img) or cv2.imshow(img).

important: in this kind of error you should look for simple mistakes in most cases

besides syntax error, I should say once I had same problem and it was because of bad name I have chosen for function. I have never searched for the reason but I remember that I copied another function and change it to use. I add "1" after the name to changed the function name and I got this error.

You can also click on the Formulas tab in Excel and select Show Formulas, then use the regular "Find" and "Replace" function. This should not affect the rest of your formula.

Surprised to not find a solution using a generator for timing. I just designed this one for my own purposes.

This solution: single threaded, no object instantiation each period, uses generator for times, rock solid on timing down to precision of the time module (unlike several of the solutions I've tried from stack exchange).

Note: for Python 2.x, replace next(g) below with g.next().

import time

def do_every(period,f,*args):
    def g_tick():
        t = time.time()
        while True:
            t += period
            yield max(t - time.time(),0)
    g = g_tick()
    while True:
        time.sleep(next(g))
        f(*args)

def hello(s):
    print('hello {} ({:.4f})'.format(s,time.time()))
    time.sleep(.3)

do_every(1,hello,'foo')

Results in, for example:

hello foo (1421705487.5811)
hello foo (1421705488.5811)
hello foo (1421705489.5809)
hello foo (1421705490.5830)
hello foo (1421705491.5803)
hello foo (1421705492.5808)
hello foo (1421705493.5811)
hello foo (1421705494.5811)
hello foo (1421705495.5810)
hello foo (1421705496.5811)
hello foo (1421705497.5810)
hello foo (1421705498.5810)
hello foo (1421705499.5809)
hello foo (1421705500.5811)
hello foo (1421705501.5811)
hello foo (1421705502.5811)
hello foo (1421705503.5810)

Note that this example includes a simulation of the cpu doing something else for .3 seconds each period. If you changed it to be random each time it wouldn't matter. The max in the yield line serves to protect sleep from negative numbers in case the function being called takes longer than the period specified. In that case it would execute immediately and make up the lost time in the timing of the next execution.

The accepted answer by @kevinsa5 is correct, but you might be thinking "I swear this code used to work and now it doesn't," and you would be right.

There was an API change in the MySQLdb library between 1.2.3 and 1.2.5. The 1.2.3 versions supported

cursor.execute("SELECT * FROM foo WHERE bar = %s", 'baz')

but the 1.2.5 versions require

cursor.execute("SELECT * FROM foo WHERE bar = %s", ['baz'])

as the other answers state. I can't find the change in the changelogs, and it's possible the earlier behavior was considered a bug.

The Ubuntu 14.04 repository has python-mysqldb 1.2.3, but Ubuntu 16.04 and later have python-mysqldb 1.3.7+.

If you're dealing with a legacy codebase that requires the old behavior but your platform is a newish Ubuntu, install MySQLdb from PyPI instead:

$ pip install MySQL-python==1.2.3

yes, but why !!??

   Select CustomerID,
     Min(Case DBColumnName When 'FirstName' Then Data End) FirstName,
     Min(Case DBColumnName When 'MiddleName' Then Data End) MiddleName,
     Min(Case DBColumnName When 'LastName' Then Data End) LastName,
     Min(Case DBColumnName When 'Date' Then Data End) Date
   From table
   Group By CustomerId

Using pipes seems weird to me. Anyway you should use the logical and Bash operator:

$ cp /templates/apple /templates/used && cp /templates/apple /templates/inuse && rm /templates/apples

If the cp commands fail, the rm will not be executed.

Or, you can make a more elaborated command line using a for loop and cmp.

The with keywork is introduced in C# version 9! you can use it to create copy of object like follows

Person brother = person with { FirstName = "Paul" };

"The above line creates a new Person record where the LastName property is a copy of person, and the FirstName is "Paul". You can set any number of properties in a with-expression. Any of the synthesized members except the "clone" method may be written by you. If a record type has a method that matches the signature of any synthesized method, the compiler doesn't synthesize that method."

UPDATE:

At the time this answer is written, C#9 is not officially released but in preview only. However, it is planned to be shipped along with .NET 5.0 in November 2020

for more information, check the record types.

Added to @muffls answer so that this works with all twitter bootstrap collapse and makes the change to the arrow before the animatation starts.

$('.collapse').on('show', function(){
    $(this).parent().find(".icon-chevron-left").removeClass("icon-chevron-left").addClass("icon-chevron-down");
}).on('hide', function(){
    $(this).parent().find(".icon-chevron-down").removeClass("icon-chevron-down").addClass("icon-chevron-left");
});

Depending on your HTML structure you may need to modify the parent().

Here is a mockable singleton using CRTP. It relies on a little helper to enforce a single object at any one time (at most). To enforce a single object over program execution, remove the reset (which we find useful for tests).

A ConcreteSinleton can be implemented like this:

class ConcreteSingleton : public Singleton<ConcreteSingleton>
{
public:
  ConcreteSingleton(const Singleton<ConcreteSingleton>::PrivatePass&)
      : Singleton<StandardPaths>::Singleton{pass}
  {}
  
  // ... concrete interface
  int f() const {return 42;}

};

And then used with

ConcreteSingleton::instance().f();

In addition to what eugene and stevenl posted, you might encounter problems with using both <> and <STDIN> in one script: <> iterates through (=concatenating) all files given as command line arguments.

However, should a user ever forget to specify a file on the command line, it will read from STDIN, and your code will wait forever on input

A more recent solution is using the The PerformanceNavigation interface:

if(!!window.performance && window.performance.navigation.type === 2)
{
    console.log('Reloading');
    window.location.reload();
}

Where the value 2 means "The page was accessed by navigating into the history".

just use class='text-center' in element for center heading.

<h2 class="text-center">sample center heading</h2>

use class='text-left' in element for left heading, and use class='text-right' in element for right heading.

Many hours spent to clarify what was that. Please, read this post to get the advanced .HTACCESS codes and learn what they do.

You can use:

Header append Vary "Accept-Encoding"
#or
Header set Vary "Accept-Encoding"

Mostly you don't see a difference, unless you are using set -u:

/home/user1> var=""
/home/user1> echo $var

/home/user1> set -u
/home/user1> echo $var

/home/user1> unset var
/home/user1> echo $var
-bash: var: unbound variable

So really, it depends on how you are going to test the variable.

I will add that my preferred way of testing if it is set is:

[[ -n $var ]]  # True if the length of $var is non-zero

or

[[ -z $var ]]  # True if zero length
