Programs & Examples On #Powercfg

A few points:

1) "DataBind()" is only for web apps (not windows apps).

2) Your code looks very 'JAVAish' (not a bad thing, just an observation).

Try this:

mnuActionLanguage.ComboBox.DataSource = languages;

If that doesn't work... then I'm assuming that your datasource is being stepped on somewhere else in the code.

If you want to trigger the keypress or keydown event then all you have to do is:

var e = jQuery.Event("keydown");
e.which = 50; // # Some key code value
$("input").trigger(e);

You should first submit your form and then change the value of your submit:

onClick="this.form.submit(); this.disabled=true; this.value='Sending…'; "

To start server locally paste the below code in package.json and run npm start in command line.

"scripts": { "start": "http-server -c-1 -p 8081" },

just one line code to get simple Date format :

SimpleDateFormat.getDateInstance().format(Date())

output : 18-May-2020

SimpleDateFormat.getDateTimeInstance().format(Date())

output : 18-May-2020 11:00:39 AM

SimpleDateFormat.getTimeInstance().format(Date())

output : 11:00:39 AM

Hope this answer is enough to get this Date and Time Format ... :)

I found this resource that details the various methods: How to embed TIFF files in HTML documents

As mentioned, it will very much depend on browser support for the format. Viewing that page in Chrome on Windows didn't display any of the images.

It would also be helpful if you posted the code you've tried already.

Lazy Set

VARIABLE = value

Normal setting of a variable, but any other variables mentioned with the value field are recursively expanded with their value at the point at which the variable is used, not the one it had when it was declared

Immediate Set

VARIABLE := value

Setting of a variable with simple expansion of the values inside - values within it are expanded at declaration time.

Lazy Set If Absent

VARIABLE ?= value

Setting of a variable only if it doesn't have a value. value is always evaluated when VARIABLE is accessed. It is equivalent to

ifeq ($(origin FOO), undefined)
  FOO = bar
endif

See the documentation for more details.

Append

VARIABLE += value

Appending the supplied value to the existing value (or setting to that value if the variable didn't exist)

Using the arrow function, and sorting by the second string field

var a = [[12, 'CCC'], [58, 'AAA'], [57, 'DDD'], [28, 'CCC'],[18, 'BBB']];_x000D_
a.sort((a, b) => a[1].localeCompare(b[1]));_x000D_
console.log(a)

This is not possible, as you say, from a security stand point. The only way you could simulate it, is by creating a modeless dialog window.

There are many third-party javascript-plugins that you could use to fake this effect so you do not have to write all that code.

It depends of the language, and of the architecture you are using.

For example, in a php platform, you can format almost language with GeSHi

As bluish comments, GeSHi is a generic syntax highlighter, with no beautification feature. It is more used on the server side, and combine it with a beautification tool can be tricky, as illustrated with this GeSHi drupal ticket.

I liked the TimeUnit-based approach until I found out that it only covers the trivial cases where the number of how many units of one timeunit are in the next higher unit is fixed. This breaks apart when you want to know how many months, year, etc are in between.

here is a counting approach, not as efficient as some others, but it seems to work for me and takes into account DST, too.

public static String getOffsetAsString( Calendar cNow, Calendar cThen) {
    Calendar cBefore;
    Calendar cAfter;
    if ( cNow.getTimeInMillis() < cThen.getTimeInMillis()) {
        cBefore = ( Calendar) cNow.clone();
        cAfter = cThen;
    } else {
        cBefore = ( Calendar) cThen.clone();
        cAfter = cNow;
    }
    // compute diff
    Map<Integer, Long> diffMap = new HashMap<Integer, Long>();
    int[] calFields = { Calendar.YEAR, Calendar.MONTH, Calendar.DAY_OF_MONTH, Calendar.HOUR_OF_DAY, Calendar.MINUTE, Calendar.SECOND, Calendar.MILLISECOND};
    for ( int i = 0; i < calFields.length; i++) {
        int field = calFields[ i];
        long    d = computeDist( cAfter, cBefore, field);
        diffMap.put( field, d);
    }
    final String result = String.format( "%dY %02dM %dT %02d:%02d:%02d.%03d",
            diffMap.get( Calendar.YEAR), diffMap.get( Calendar.MONTH), diffMap.get( Calendar.DAY_OF_MONTH), diffMap.get( Calendar.HOUR_OF_DAY), diffMap.get( Calendar.MINUTE), diffMap.get( Calendar.SECOND), diffMap.get( Calendar.MILLISECOND));
    return result;
}

private static int computeDist( Calendar cAfter, Calendar cBefore, int field) {
    cBefore.setLenient( true);
    System.out.print( "D " + new Date( cBefore.getTimeInMillis()) + " --- " + new Date( cAfter.getTimeInMillis()) + ": ");
    int count = 0;
    if ( cAfter.getTimeInMillis() > cBefore.getTimeInMillis()) {
        int fVal = cBefore.get( field);
        while ( cAfter.getTimeInMillis() >= cBefore.getTimeInMillis()) {
            count++;
            fVal = cBefore.get( field);
            cBefore.set( field, fVal + 1);
            System.out.print( count + "/"  + ( fVal + 1) + ": " + new Date( cBefore.getTimeInMillis()) + " ] ");
        }
        int result = count - 1;
        cBefore.set( field, fVal);
        System.out.println( "" + result + " at: " + field + " cb = " + new Date( cBefore.getTimeInMillis()));
        return result;
    }
    return 0;
}

Is it possible to select an element if it contains a specific child element?

Unfortunately not yet.

The CSS2 and CSS3 selector specifications do not allow for any sort of parent selection.

A Note About Specification Changes

This is a disclaimer about the accuracy of this post from this point onward. Parent selectors in CSS have been discussed for many years. As no consensus has been found, changes keep happening. I will attempt to keep this answer up-to-date, however be aware that there may be inaccuracies due to changes in the specifications.

An older "Selectors Level 4 Working Draft" described a feature which was the ability to specify the "subject" of a selector. This feature has been dropped and will not be available for CSS implementations.

The subject was going to be the element in the selector chain that would have styles applied to it.

<p><span>lorem</span> ipsum dolor sit amet</p>
<p>consecteture edipsing elit</p>

This selector would style the span element

p span {
    color: red;
}

This selector would style the p element

!p span {
    color: red;
}

A more recent "Selectors Level 4 Editor’s Draft" includes "The Relational Pseudo-class: :has()"

:has() would allow an author to select an element based on its contents. My understanding is it was chosen to provide compatibility with jQuery's custom :has() pseudo-selector*.

In any event, continuing the example from above, to select the p element that contains a span one could use:

p:has(span) {
    color: red;
}

_{* This makes me wonder if jQuery had implemented selector subjects whether subjects would have remained in the specification.}

You call writer.close(); in writeToFile so the writer has been closed the second time you call writeToFile.

Why don't you merge FileStatus into writeToFile?

You will first need to update the local formulas by doing

brew update

and then upgrade the package by doing

brew upgrade formula-name

An example would be if i wanted to upgrade mongodb, i would do something like this, assuming mongodb was already installed :

brew update && brew upgrade mongodb && brew cleanup mongodb

Add these lines to your web.config file:

<system.data>
    <DbProviderFactories>
               <add name="MySQL Data Provider" invariant="MySql.Data.MySqlClient" description=".Net Framework Data Provider for MySQL" type="MySql.Data.MySqlClient.MySqlClientFactory,MySql.Data,  Version=6.6.4.0, Culture=neutral, PublicKeyToken=C5687FC88969C44D"/>
    </DbProviderFactories>
</system.data>

Change your provider from MySQL to SQL Server or whatever database provider you are connecting to.

One big and great approach is to load the module from a NgModuleFactory, you can load a module inside another module by calling this:

constructor(private loader: NgModuleFactoryLoader, private injector: Injector) {}

loadModule(path: string) {
    this.loader.load(path).then((moduleFactory: NgModuleFactory<any>) => {
        const entryComponent = (<any>moduleFactory.moduleType).entry;
        const moduleRef = moduleFactory.create(this.injector);
        const compFactory = moduleRef.componentFactoryResolver.resolveComponentFactory(entryComponent);
        this.lazyOutlet.createComponent(compFactory);
    });
}

I got this from here.

the accepted answer does not work any longer with laravel 5.3 because mailable tries to access ->email and results in

ErrorException in Mailable.php line 376: Trying to get property of non-object

a working code for laravel 5.3 is this:

$users_temp = explode(',', '[email protected],[email protected]');
    $users = [];
    foreach($users_temp as $key => $ut){
      $ua = [];
      $ua['email'] = $ut;
      $ua['name'] = 'test';
      $users[$key] = (object)$ua;
    }
 Mail::to($users)->send(new OrderAdminSendInvoice($o));

CREATE GLOBAL TEMPORARY TABLE Table_name
    (startdate DATE,
     enddate DATE,
     class CHAR(20))
  ON COMMIT DELETE ROWS;

If you also want to allow empty extensions, this is the shortest I could come up with:

echo 'hello.txt' | sed -r 's/.+\.(.+)|.*/\1/' # EXTENSION
echo 'hello.txt' | sed -r 's/(.+)\..+|(.*)/\1\2/' # FILENAME

1st line explained: It matches PATH.EXT or ANYTHING and replaces it with EXT. If ANYTHING was matched, the ext group is not captured.

This is taken from the Python docs:

Identifiers (also referred to as names) are described by the following lexical definitions:

identifier ::=  (letter|"_") (letter | digit | "_")*

letter     ::=  lowercase | uppercase

lowercase  ::=  "a"..."z"

uppercase  ::=  "A"..."Z"

digit      ::=  "0"..."9"

Identifiers are unlimited in length. Case is significant.

That should explain how to name your variables.

This can be achieved with the onresize property of the GlobalEventHandlers interface in JavaScript, by assigning a function to the onresize property, like so:

window.onresize = functionRef;

The following code snippet demonstrates this, by console logging the innerWidth and innerHeight of the window whenever it's resized. (The resize event fires after the window has been resized)

function resize() {_x000D_
  console.log("height: ", window.innerHeight, "px");_x000D_
  console.log("width: ", window.innerWidth, "px");_x000D_
}_x000D_
_x000D_
window.onresize = resize;

<p>In order for this code snippet to work as intended, you will need to either shrink your browser window down to the size of this code snippet, or fullscreen this code snippet and resize from there.</p>

[...] How should Java Comparator class be declared to sort the arrays by their first elements in decreasing order [...]

Here's a complete example using Java 8:

import java.util.*;

public class Test {

    public static void main(String args[]) {

        int[][] twoDim = { {1, 2}, {3, 7}, {8, 9}, {4, 2}, {5, 3} };

        Arrays.sort(twoDim, Comparator.comparingInt(a -> a[0])
                                      .reversed());

        System.out.println(Arrays.deepToString(twoDim));
    }
}

Output:

[[8, 9], [5, 3], [4, 2], [3, 7], [1, 2]]

For Java 7 you can do:

Arrays.sort(twoDim, new Comparator<int[]>() {
    @Override
    public int compare(int[] o1, int[] o2) {
        return Integer.compare(o2[0], o1[0]);
    }
});

If you unfortunate enough to work on Java 6 or older, you'd do:

Arrays.sort(twoDim, new Comparator<int[]>() {
    @Override
    public int compare(int[] o1, int[] o2) {
        return ((Integer) o2[0]).compareTo(o1[0]);
    }
});

>>> 2 == 2.0
True
>>> 2 is 2.0
False

Use ==

You can use the Tuple class as a substitute for an anonymous types when returning is necessary:

Note: Tuple can have up to 8 parameters.

return Tuple.Create(variable1, variable2);

Or, for the example from the original post:

public List<Tuple<SomeType, AnotherType>> TheMethod(SomeParameter)
{
  using (MyDC TheDC = new MyDC())
  {
     var TheQueryFromDB = (....
                           select Tuple.Create(..., ...)
                           ).ToList();

      return TheQueryFromDB.ToList();
    }
}

http://msdn.microsoft.com/en-us/library/system.tuple(v=vs.110).aspx

can you try it once...

String dob="your date String";
String dobis=null;
final DateFormat df = new SimpleDateFormat("yyyy-MMM-dd");
final Calendar c = Calendar.getInstance();
try {
    if(dob!=null && !dob.isEmpty() && dob != "")
    {
    c.setTime(df.parse(dob));
    int month=c.get(Calendar.MONTH);
    month=month+1;
    dobis=c.get(Calendar.YEAR)+"-"+month+"-"+c.get(Calendar.DAY_OF_MONTH);
    }

}

DateTime TaskStart = DateTime.Parse(dr["TaskStart"].ToString());

Lets assume you created a Ubuntu VM on your local machine. It's IP address is 192.168.1.104.

You login into VM, and installed Kubernetes. Then you created a pod where nginx image running on it.

1- If you want to access this nginx pod inside your VM, you will create a ClusterIP bound to that pod for example:

$ kubectl expose deployment nginxapp --name=nginxclusterip --port=80 --target-port=8080

Then on your browser you can type ip address of nginxclusterip with port 80, like:

http://10.152.183.2:80

2- If you want to access this nginx pod from your host machine, you will need to expose your deployment with NodePort. For example:

$ kubectl expose deployment nginxapp --name=nginxnodeport --port=80 --target-port=8080 --type=NodePort

Now from your host machine you can access to nginx like:

http://192.168.1.104:31865/

In my dashboard they appear as:

Below is a diagram shows basic relationship.

Simple and crisp...:

private OnItemSelectedListener OnCatSpinnerCL = new AdapterView.OnItemSelectedListener() {
    public void onItemSelected(AdapterView<?> parent, View view, int pos, long id) {

       ((TextView) parent.getChildAt(0)).setTextColor(Color.BLUE);
       ((TextView) parent.getChildAt(0)).setTextSize(5);

    }

    public void onNothingSelected(AdapterView<?> parent) {

    }
};

Try with:

select p from Person p left join FETCH p.address a where...

It works for me in a similar with JPA2/EclipseLink, but it seems this feature is present in JPA1 too:

in bootstrap 3.0.3 you can do it by modifying the popover class

.popover {
    min-width: 200px;
    max-width: 400px;
}

Here is what you can do using jquery:

$('#A_ID').click(function (e) { //#A_ID is an example. Use the id of your Anchor
    $('html, body').animate({
        scrollTop: $('#DIV_ID').offset().top - 20 //#DIV_ID is an example. Use the id of your destination on the page
    }, 'slow');
});

Here too I can reproduce this problem with scrapy and psycopg2 (both require C++ compiling), even though I have Microsoft Visual C++ Compiler for Python 2.7 installed.

It has to be noted that I use virtualenv. From your post I'm not sure whether you do the same.

Anyway I tried to skip the activation of the virtual environment. Then both scrapy and psycopg2 installed fine.

My hypothesis: there is a conflict between this 2014 C++ compiler for Python and virtualenv. I do not know why nor how to solve it (and I'd be glad if someone can suggest a workaround).

An alternative would be to use Font-Awesome for icons:

Including Font-Awesome

Open Font-Awesome on CDNJS and copy the CSS url of the latest version:

<link rel="stylesheet" href="<url>">

Or in CSS

@import url("<url>");

For example (note, the version will change):

<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/4.7.0/css/font-awesome.css">

Usage:

<i class="fa fa-bed"></i>

It contains a lot of icons!

In my case, the error was caused because I have no permissions in the repository.

Your example is basically what I'm using. It never works on the emulator, however, because the emulator doesn't have any ringtones by default, and content://settings/system/ringtone doesn't resolve to anything playable. It works fine on my actual phone.

I had the same problem I used the solution offered above - I dropped the SYNONYM, created a VIEW with the same name as the synonym. it had a select using the dblink , and gave GRANT SELECT to the other schema It worked great.

1. Open your Atom IDE
2. press ctrl+shift+P and search for "platformio-ide-terminal" package
3. press install
4. once installed press ctrl+~ (tilde above tab key in a standard keyboard)
5. terminal opens enjoy!!!

The proper way would be to use $_SERVER["PHP_SELF"] (in conjunction with htmlspecialchars to avoid possible exploits). You can also just skip the action= part empty, which is not W3C valid, but currently works in most (all?) browsers - the default is to submit to self if it's empty.

Here is an example form that takes a name and email, and then displays the values you have entered upon submit:

<?php if (!empty($_POST)): ?>
    Welcome, <?php echo htmlspecialchars($_POST["name"]); ?>!<br>
    Your email is <?php echo htmlspecialchars($_POST["email"]); ?>.<br>
<?php else: ?>
    <form action="<?php echo htmlspecialchars($_SERVER["PHP_SELF"]); ?>" method="post">
        Name: <input type="text" name="name"><br>
        Email: <input type="text" name="email"><br>
        <input type="submit">
    </form>
<?php endif; ?>

On CentOS Linux, Python3.6, I edited this file (make a backup copy first)

/usr/lib/python3.6/site-packages/certifi/cacert.pem

to the end of the file, I added my public certificate from my .pem file. you should be able to obtain the .pem file from your ssl certificate provider.

Rails 6.1 added a new 'syntax' for comparison operators in where conditions, for example:

Post.where('id >': 9)
Post.where('id >=': 9)
Post.where('id <': 3)
Post.where('id <=': 3)

So your query can be rewritten as follows:

Note
  .where(user_id: current_user.id, notetype: p[:note_type], 'date >', p[:date])
  .order(date: :asc, created_at: :asc)

Here is a link to PR where you can find more examples.

You should be able to match it with: /<primaryAddress>(.+?)<\/primaryAddress>/

The content between the tags will be in the matched group.

SELECT CONVERT(CAST(column as BINARY) USING utf8) as column FROM table 

    import java.util.Scanner;

    public class LeapYear {
    public static void main(String[] args) {
        // TODO Auto-generated method stub
        Scanner input = new Scanner(System.in);
        System.out.print("Enter the year then press Enter : ");
        int year = input.nextInt();

        if ((year < 1580) && (year % 4 == 0)) {
            System.out.println("Leap year: " + year);
        } else {
            if ((year % 4 == 0) && (year % 100 != 0) || (year % 400 == 0)) {
                System.out.println("Leap year: " + year);
            } else {
                System.out.println(year + " not a leap year!");
            }

        }
    }
}

Simply saying, any() does this work : according to the condition even if it encounters one fulfilling value in the list, it returns true, else it returns false.

list = [2,-3,-4,5,6]

a = any(x>0 for x in lst)

print a:
True


list = [2,3,4,5,6,7]

a = any(x<0 for x in lst)

print a:
False

Because InfluxDB is a bit painful about deletes, we use a schema that has a boolean field called "ForUse", which looks like this when posting via the line protocol (v0.9):

your_measurement,your_tag=foo ForUse=TRUE,value=123.5 1262304000000000000

You can overwrite the same measurement, tag key, and time with whatever field keys you send, so we do "deletes" by setting "ForUse" to false, and letting retention policy keep the database size under control.

Since the overwrite happens seamlessly, you can retroactively add the schema too. Noice.

This has been answered before (although this question was first!):

"You should use java.net.URI to do this, as the URLDecoder class does x-www-form-urlencoded decoding which is wrong (despite the name, it's for form data)."

As URL class documentation states:

The recommended way to manage the encoding and decoding of URLs is to use URI, and to convert between these two classes using toURI() and URI.toURL().

The URLEncoder and URLDecoder classes can also be used, but only for HTML form encoding, which is not the same as the encoding scheme defined in RFC2396.

Basically:

String url = "https%3A%2F%2Fmywebsite%2Fdocs%2Fenglish%2Fsite%2Fmybook.do%3Frequest_type";
System.out.println(new java.net.URI(url).getPath());

will give you:

https://mywebsite/docs/english/site/mybook.do?request_type

the answer is already exist above, but I would like to add some thing.. you can specify the following in your @font-face

@font-face {
  font-family: 'Name You Font';
  src: url('assets/font/xxyourfontxxx.eot');
  src: local('Cera Pro Medium'), local('CeraPro-Medium'),
  url('assets/font/xxyourfontxxx.eot?#iefix') format('embedded-opentype'),
  url('assets/font/xxyourfontxxx.woff') format('woff'),
  url('assets/font/xxyourfontxxx.ttf') format('truetype');
  font-weight: 500;
  font-style: normal;
}

So you can just indicate your fontfamily name that you already choosed

NOTE: the font-weight and font-style depend on your .woff .ttf ... files

I don't think you understand how \n works. The resulting string still just contains a byte with value 10. This is represented in javascript source code with \n.

The code snippet you posted doesn't actually work, but if it did, the newline would be equivalent to \n, unless it's a windows-style newline, in which case it would be \r\n. (but even that the replace would still work).

If you want to use them like that, define the function with the variable names as normal:

def my_function(school, standard, city, name):
    schoolName  = school
    cityName = city
    standardName = standard
    studentName = name

Now you can use ** when you call the function:

data = {'school':'DAV', 'standard': '7', 'name': 'abc', 'city': 'delhi'}

my_function(**data)

and it will work as you want.

P.S. Don't use reserved words such as class.(e.g., use klass instead)

Here are some up-to-date albeit narrow findings of mine with GCC 4.7.2 and Clang 3.2 for C++.

UPDATE: GCC 4.8.1 v clang 3.3 comparison appended below.

UPDATE: GCC 4.8.2 v clang 3.4 comparison is appended to that.

I maintain an OSS tool that is built for Linux with both GCC and Clang, and with Microsoft's compiler for Windows. The tool, coan, is a preprocessor and analyser of C/C++ source files and codelines of such: its computational profile majors on recursive-descent parsing and file-handling. The development branch (to which these results pertain) comprises at present around 11K LOC in about 90 files. It is coded, now, in C++ that is rich in polymorphism and templates and but is still mired in many patches by its not-so-distant past in hacked-together C. Move semantics are not expressly exploited. It is single-threaded. I have devoted no serious effort to optimizing it, while the "architecture" remains so largely ToDo.

I employed Clang prior to 3.2 only as an experimental compiler because, despite its superior compilation speed and diagnostics, its C++11 standard support lagged the contemporary GCC version in the respects exercised by coan. With 3.2, this gap has been closed.

My Linux test harness for current coan development processes roughly 70K sources files in a mixture of one-file parser test-cases, stress tests consuming 1000s of files and scenario tests consuming < 1K files. As well as reporting the test results, the harness accumulates and displays the totals of files consumed and the run time consumed in coan (it just passes each coan command line to the Linux time command and captures and adds up the reported numbers). The timings are flattered by the fact that any number of tests which take 0 measurable time will all add up to 0, but the contribution of such tests is negligible. The timing stats are displayed at the end of make check like this:

coan_test_timer: info: coan processed 70844 input_files.
coan_test_timer: info: run time in coan: 16.4 secs.
coan_test_timer: info: Average processing time per input file: 0.000231 secs.

I compared the test harness performance as between GCC 4.7.2 and Clang 3.2, all things being equal except the compilers. As of Clang 3.2, I no longer require any preprocessor differentiation between code tracts that GCC will compile and Clang alternatives. I built to the same C++ library (GCC's) in each case and ran all the comparisons consecutively in the same terminal session.

The default optimization level for my release build is -O2. I also successfully tested builds at -O3. I tested each configuration 3 times back-to-back and averaged the 3 outcomes, with the following results. The number in a data-cell is the average number of microseconds consumed by the coan executable to process each of the ~70K input files (read, parse and write output and diagnostics).

          | -O2 | -O3 |O2/O3|
----------|-----|-----|-----|
GCC-4.7.2 | 231 | 237 |0.97 |
----------|-----|-----|-----|
Clang-3.2 | 234 | 186 |1.25 |
----------|-----|-----|------
GCC/Clang |0.99 | 1.27|

Any particular application is very likely to have traits that play unfairly to a compiler's strengths or weaknesses. Rigorous benchmarking employs diverse applications. With that well in mind, the noteworthy features of these data are:

1. -O3 optimization was marginally detrimental to GCC
2. -O3 optimization was importantly beneficial to Clang
3. At -O2 optimization, GCC was faster than Clang by just a whisker
4. At -O3 optimization, Clang was importantly faster than GCC.

A further interesting comparison of the two compilers emerged by accident shortly after those findings. Coan liberally employs smart pointers and one such is heavily exercised in the file handling. This particular smart-pointer type had been typedef'd in prior releases for the sake of compiler-differentiation, to be an std::unique_ptr<X> if the configured compiler had sufficiently mature support for its usage as that, and otherwise an std::shared_ptr<X>. The bias to std::unique_ptr was foolish, since these pointers were in fact transferred around, but std::unique_ptr looked like the fitter option for replacing std::auto_ptr at a point when the C++11 variants were novel to me.

In the course of experimental builds to gauge Clang 3.2's continued need for this and similar differentiation, I inadvertently built std::shared_ptr<X> when I had intended to build std::unique_ptr<X>, and was surprised to observe that the resulting executable, with default -O2 optimization, was the fastest I had seen, sometimes achieving 184 msecs. per input file. With this one change to the source code, the corresponding results were these;

          | -O2 | -O3 |O2/O3|
----------|-----|-----|-----|
GCC-4.7.2 | 234 | 234 |1.00 |
----------|-----|-----|-----|
Clang-3.2 | 188 | 187 |1.00 |
----------|-----|-----|------
GCC/Clang |1.24 |1.25 |

The points of note here are:

1. Neither compiler now benefits at all from -O3 optimization.
2. Clang beats GCC just as importantly at each level of optimization.
3. GCC's performance is only marginally affected by the smart-pointer type change.
4. Clang's -O2 performance is importantly affected by the smart-pointer type change.

Before and after the smart-pointer type change, Clang is able to build a substantially faster coan executable at -O3 optimisation, and it can build an equally faster executable at -O2 and -O3 when that pointer-type is the best one - std::shared_ptr<X> - for the job.

An obvious question that I am not competent to comment upon is why Clang should be able to find a 25% -O2 speed-up in my application when a heavily used smart-pointer-type is changed from unique to shared, while GCC is indifferent to the same change. Nor do I know whether I should cheer or boo the discovery that Clang's -O2 optimization harbours such huge sensitivity to the wisdom of my smart-pointer choices.

UPDATE: GCC 4.8.1 v clang 3.3

The corresponding results now are:

          | -O2 | -O3 |O2/O3|
----------|-----|-----|-----|
GCC-4.8.1 | 442 | 443 |1.00 |
----------|-----|-----|-----|
Clang-3.3 | 374 | 370 |1.01 |
----------|-----|-----|------
GCC/Clang |1.18 |1.20 |

The fact that all four executables now take a much greater average time than previously to process 1 file does not reflect on the latest compilers' performance. It is due to the fact that the later development branch of the test application has taken on lot of parsing sophistication in the meantime and pays for it in speed. Only the ratios are significant.

The points of note now are not arrestingly novel:

• GCC is indifferent to -O3 optimization
• clang benefits very marginally from -O3 optimization
• clang beats GCC by a similarly important margin at each level of optimization.

Comparing these results with those for GCC 4.7.2 and clang 3.2, it stands out that GCC has clawed back about a quarter of clang's lead at each optimization level. But since the test application has been heavily developed in the meantime one cannot confidently attribute this to a catch-up in GCC's code-generation. (This time, I have noted the application snapshot from which the timings were obtained and can use it again.)

UPDATE: GCC 4.8.2 v clang 3.4

I finished the update for GCC 4.8.1 v Clang 3.3 saying that I would stick to the same coan snaphot for further updates. But I decided instead to test on that snapshot (rev. 301) and on the latest development snapshot I have that passes its test suite (rev. 619). This gives the results a bit of longitude, and I had another motive:

My original posting noted that I had devoted no effort to optimizing coan for speed. This was still the case as of rev. 301. However, after I had built the timing apparatus into the coan test harness, every time I ran the test suite the performance impact of the latest changes stared me in the face. I saw that it was often surprisingly big and that the trend was more steeply negative than I felt to be merited by gains in functionality.

By rev. 308 the average processing time per input file in the test suite had well more than doubled since the first posting here. At that point I made a U-turn on my 10 year policy of not bothering about performance. In the intensive spate of revisions up to 619 performance was always a consideration and a large number of them went purely to rewriting key load-bearers on fundamentally faster lines (though without using any non-standard compiler features to do so). It would be interesting to see each compiler's reaction to this U-turn,

Here is the now familiar timings matrix for the latest two compilers' builds of rev.301:

coan - rev.301 results

          | -O2 | -O3 |O2/O3|
----------|-----|-----|-----|
GCC-4.8.2 | 428 | 428 |1.00 |
----------|-----|-----|-----|
Clang-3.4 | 390 | 365 |1.07 |
----------|-----|-----|------
GCC/Clang | 1.1 | 1.17|

The story here is only marginally changed from GCC-4.8.1 and Clang-3.3. GCC's showing is a trifle better. Clang's is a trifle worse. Noise could well account for this. Clang still comes out ahead by -O2 and -O3 margins that wouldn't matter in most applications but would matter to quite a few.

And here is the matrix for rev. 619.

coan - rev.619 results

          | -O2 | -O3 |O2/O3|
----------|-----|-----|-----|
GCC-4.8.2 | 210 | 208 |1.01 |
----------|-----|-----|-----|
Clang-3.4 | 252 | 250 |1.01 |
----------|-----|-----|------
GCC/Clang |0.83 | 0.83|

Taking the 301 and the 619 figures side by side, several points speak out.

• I was aiming to write faster code, and both compilers emphatically vindicate my efforts. But:

• GCC repays those efforts far more generously than Clang. At -O2 optimization Clang's 619 build is 46% faster than its 301 build: at -O3 Clang's improvement is 31%. Good, but at each optimization level GCC's 619 build is more than twice as fast as its 301.

• GCC more than reverses Clang's former superiority. And at each optimization level GCC now beats Clang by 17%.

• Clang's ability in the 301 build to get more leverage than GCC from -O3 optimization is gone in the 619 build. Neither compiler gains meaningfully from -O3.

I was sufficiently surprised by this reversal of fortunes that I suspected I might have accidentally made a sluggish build of clang 3.4 itself (since I built it from source). So I re-ran the 619 test with my distro's stock Clang 3.3. The results were practically the same as for 3.4.

So as regards reaction to the U-turn: On the numbers here, Clang has done much better than GCC at at wringing speed out of my C++ code when I was giving it no help. When I put my mind to helping, GCC did a much better job than Clang.

I don't elevate that observation into a principle, but I take the lesson that "Which compiler produces the better binaries?" is a question that, even if you specify the test suite to which the answer shall be relative, still is not a clear-cut matter of just timing the binaries.

Is your better binary the fastest binary, or is it the one that best compensates for cheaply crafted code? Or best compensates for expensively crafted code that prioritizes maintainability and reuse over speed? It depends on the nature and relative weights of your motives for producing the binary, and of the constraints under which you do so.

And in any case, if you deeply care about building "the best" binaries then you had better keep checking how successive iterations of compilers deliver on your idea of "the best" over successive iterations of your code.

UPDATE: 9/24/16 Angular 2.0 Stable

This question gets a lot of traffic still, so, I wanted to update it. With the insanity of changes from Alpha, Beta, and 7 RC candidates, I stopped updating my SO answers until they went stable.

This is the perfect case for using Subjects and ReplaySubjects

I personally prefer to use ReplaySubject(1) as it allows the last stored value to be passed when new subscribers attach even when late:

let project = new ReplaySubject(1);

//subscribe
project.subscribe(result => console.log('Subscription Streaming:', result));

http.get('path/to/whatever/projects/1234').subscribe(result => {
    //push onto subject
    project.next(result));

    //add delayed subscription AFTER loaded
    setTimeout(()=> project.subscribe(result => console.log('Delayed Stream:', result)), 3000);
});

//Output
//Subscription Streaming: 1234
//*After load and delay*
//Delayed Stream: 1234

So even if I attach late or need to load later I can always get the latest call and not worry about missing the callback.

This also lets you use the same stream to push down onto:

project.next(5678);
//output
//Subscription Streaming: 5678

But what if you are 100% sure, that you only need to do the call once? Leaving open subjects and observables isn't good but there's always that "What If?"

That's where AsyncSubject comes in.

let project = new AsyncSubject();

//subscribe
project.subscribe(result => console.log('Subscription Streaming:', result),
                  err => console.log(err),
                  () => console.log('Completed'));

http.get('path/to/whatever/projects/1234').subscribe(result => {
    //push onto subject and complete
    project.next(result));
    project.complete();

    //add a subscription even though completed
    setTimeout(() => project.subscribe(project => console.log('Delayed Sub:', project)), 2000);
});

//Output
//Subscription Streaming: 1234
//Completed
//*After delay and completed*
//Delayed Sub: 1234

Awesome! Even though we closed the subject it still replied with the last thing it loaded.

Another thing is how we subscribed to that http call and handled the response. Map is great to process the response.

public call = http.get(whatever).map(res => res.json())

But what if we needed to nest those calls? Yes you could use subjects with a special function:

getThing() {
    resultSubject = new ReplaySubject(1);

    http.get('path').subscribe(result1 => {
        http.get('other/path/' + result1).get.subscribe(response2 => {
            http.get('another/' + response2).subscribe(res3 => resultSubject.next(res3))
        })
    })
    return resultSubject;
}
var myThing = getThing();

But that's a lot and means you need a function to do it. Enter FlatMap:

var myThing = http.get('path').flatMap(result1 => 
                    http.get('other/' + result1).flatMap(response2 => 
                        http.get('another/' + response2)));

Sweet, the var is an observable that gets the data from the final http call.

OK thats great but I want an angular2 service!

I got you:

import { Injectable } from '@angular/core';
import { Http, Response } from '@angular/http';
import { ReplaySubject } from 'rxjs';

@Injectable()
export class ProjectService {

  public activeProject:ReplaySubject<any> = new ReplaySubject(1);

  constructor(private http: Http) {}

  //load the project
  public load(projectId) {
    console.log('Loading Project:' + projectId, Date.now());
    this.http.get('/projects/' + projectId).subscribe(res => this.activeProject.next(res));
    return this.activeProject;
  }

 }

 //component

@Component({
    selector: 'nav',
    template: `<div>{{project?.name}}<a (click)="load('1234')">Load 1234</a></div>`
})
 export class navComponent implements OnInit {
    public project:any;

    constructor(private projectService:ProjectService) {}

    ngOnInit() {
        this.projectService.activeProject.subscribe(active => this.project = active);
    }

    public load(projectId:string) {
        this.projectService.load(projectId);
    }

 }

I'm a big fan of observers and observables so I hope this update helps!

Original Answer

I think this is a use case of using a Observable Subject or in Angular2 the EventEmitter.

In your service you create a EventEmitter that allows you to push values onto it. In Alpha 45 you have to convert it with toRx(), but I know they were working to get rid of that, so in Alpha 46 you may be able to simply return the EvenEmitter.

class EventService {
  _emitter: EventEmitter = new EventEmitter();
  rxEmitter: any;
  constructor() {
    this.rxEmitter = this._emitter.toRx();
  }
  doSomething(data){
    this.rxEmitter.next(data);
  }
}

This way has the single EventEmitter that your different service functions can now push onto.

If you wanted to return an observable directly from a call you could do something like this:

myHttpCall(path) {
    return Observable.create(observer => {
        http.get(path).map(res => res.json()).subscribe((result) => {
            //do something with result. 
            var newResultArray = mySpecialArrayFunction(result);
            observer.next(newResultArray);
            //call complete if you want to close this stream (like a promise)
            observer.complete();
        });
    });
}

That would allow you do this in the component: peopleService.myHttpCall('path').subscribe(people => this.people = people);

And mess with the results from the call in your service.

I like creating the EventEmitter stream on its own in case I need to get access to it from other components, but I could see both ways working...

Here's a plunker that shows a basic service with an event emitter: Plunkr

This is probably related to your database connection string or something like that.

I just solved this exception right now. What was happening is that I was using a connection string intended to be used when debugging in a different machine (the server).

I commented the wrong connection string in Web.config and uncommented the right one. Now I'm back in business... this is something I forget to look at after sometime not working in a given solution. ;)

As mentioned before, you can't use inline elements for styling pseudo classes. Before and after pseudo classes are states of elements, not actual elements. You could only possibly use JavaScript for this.

It's because you're casting to the wrong thing - you're trying to convert to a particular type, and the object that your express refers to is incompatible with that type. For example:

Object x = "this is a string";
InputStream y = (InputStream) x; // This will throw ClassCastException

If you could provide a code sample, that would really help...

If you are using the vs code for editing then try restarting the editor.This scenario fixed my issue.I think it's the issue with editor cache.

What you have to do is to append the values as parameters in the iframe src (URL).

E.g. <iframe src="some_page.php?somedata=5&more=bacon"></iframe>

And then in some_page.php file you use php $_GET['somedata'] to retrieve it from the iframe URL. NB: Iframes run as a separate browser window in your file.

Try

string reversed(temp.rbegin(), temp.rend());

EDIT: Elaborating as requested.

string::rbegin() and string::rend(), which stand for "reverse begin" and "reverse end" respectively, return reverse iterators into the string. These are objects supporting the standard iterator interface (operator* to dereference to an element, i.e. a character of the string, and operator++ to advance to the "next" element), such that rbegin() points to the last character of the string, rend() points to the first one, and advancing the iterator moves it to the previous character (this is what makes it a reverse iterator).

Finally, the constructor we are passing these iterators into is a string constructor of the form:

template <typename Iterator>
string(Iterator first, Iterator last);

which accepts a pair of iterators of any type denoting a range of characters, and initializes the string to that range of characters.

If you go there will be trouble, but if you stay it will be double.

I'd much rather go against some supposed non-plurals naming convention than name my table after something which might be a reserved word.

If you're using Entity Framework < v6.0, then use EntityFunctions.TruncateTime If you're using Entity Framework >= v6.0, then use DbFunctions.TruncateTime

Use either (based on your EF version) around any DateTime class property you want to use inside your Linq query

Example

var list = db.Cars.Where(c=> DbFunctions.TruncateTime(c.CreatedDate) 
                                       >= DbFunctions.TruncateTime(DateTime.UtcNow));

Via Bootstrap Grid, you can easily get the cross browser compatible solution.

If the underlying goal is "How can I start a container when Docker starts?"

We can use Docker's restart policy

To add a restart policy to an existing container:

Docker: Add a restart policy to a container that was already created

Example:

docker update --restart=always <container>

You can use a for loop. but don't forget the last char must be a null character !

char * msg = new char[65546];
for(int i=0;i<65545;i++)
{
    msg[i]='0';
}
msg[65545]='\0';

There is another possible scenario I have just come across.

I did an ajax call and got data back as null, in a string format. I had to check it like this:

if(value != 'null'){}

So, null was a string which read "null" rather than really being null.

EDIT: It should be understood that I'm not selling this as the way it should be done. I had a scenario where this was the only way it could be done. I'm not sure why... perhaps the guy who wrote the back-end was presenting the data incorrectly, but regardless, this is real life. It's frustrating to see this down-voted by someone who understands that it's not quite right, and then up-voted by someone it actually helps.

Looks like your file.next() line in the while loop is throwing the NoSuchElementException since the scanner reached the end of file. Read the next() java API here

Also you should not call next() in the loop and also in the while condition. In the while condition you should check if next token is available and inside the while loop check if its equal to treasure.

This is 2013. Forget about the 2009 comments. Likewise, if you are running serious traffic loads, do not even contemplate how to make-do with a windows based memcache. When dealing with a very large scale (500+ front end web servers) and 20+ back end database servers and replicants (mysql & mssql mix), a farm of memcached servers (12 servers in group) supports multiple high volume OLTP applications answering 25K ~ 40K mc->get calls per-second. These calls are those that do NOT have to reach a database.

IMHO, this use of memcached provided SERIOUS $$$,$$$savings on CAPEX for new DB servers & licences as well as on support contracts for large commercial designs.

Plain and simple:

If Jenkins sees the build step (which is a script too) exits with non-zero code, the build is marked with a red ball (= failed).

Why exactly that happens depends on your build script.

I wrote something similar from another point-of-view but maybe it will help to read it anyway: Why does Jenkins think my build succeeded?

None of these solutions worked for me, however I was able to fix it by taking the width and subtracting the width of the scroll bar. I'm not sure how cross-browser compatible this is.

Oh. I think you're writing the workbook out 944,000 times. Your wb.write(bos) call is in the inner loop. I'm not sure this is quite consistent with the semantics of the Workbook class? From what I can tell in the Javadocs of that class, that method writes out the entire workbook to the output stream specified. And it's gonna write out every row you've added so far once for every row as the thing grows.

This explains why you're seeing exactly 1 row, too. The first workbook (with one row) to be written out to the file is all that is being displayed - and then 7GB of junk thereafter.

GET and POST are two different types of HTTP requests.

According to Wikipedia:

GET requests a representation of the specified resource. Note that GET should not be used for operations that cause side-effects, such as using it for taking actions in web applications. One reason for this is that GET may be used arbitrarily by robots or crawlers, which should not need to consider the side effects that a request should cause.

and

POST submits data to be processed (e.g., from an HTML form) to the identified resource. The data is included in the body of the request. This may result in the creation of a new resource or the updates of existing resources or both.

So essentially GET is used to retrieve remote data, and POST is used to insert/update remote data.

In addition to explaining the intended uses of each method, the spec also provides at least one practical reason for why GET should only be used to retrieve data:

Authors of services which use the HTTP protocol SHOULD NOT use GET based forms for the submission of sensitive data, because this will cause this data to be encoded in the Request-URI. Many existing servers, proxies, and user agents will log the request URI in some place where it might be visible to third parties. Servers can use POST-based form submission instead

If I understand correctly, you're looking for a multi-line representation, for readability? You want something like a here-string in other languages. Javascript can come close with this:

var x =
    "<div> \
    <span> \
    <p> \
    some text \
    </p> \

AttributeError("'str' object has no attribute 'read'",)

This means exactly what it says: something tried to find a .read attribute on the object that you gave it, and you gave it an object of type str (i.e., you gave it a string).

The error occurred here:

json.load (jsonofabitch)['data']['children']

Well, you aren't looking for read anywhere, so it must happen in the json.load function that you called (as indicated by the full traceback). That is because json.load is trying to .read the thing that you gave it, but you gave it jsonofabitch, which currently names a string (which you created by calling .read on the response).

Solution: don't call .read yourself; the function will do this, and is expecting you to give it the response directly so that it can do so.

You could also have figured this out by reading the built-in Python documentation for the function (try help(json.load), or for the entire module (try help(json)), or by checking the documentation for those functions on http://docs.python.org .

You actually don't need to use the attach at all. I had the same problem and it was resolved by removing the attach statement.

The typical approach is to use select() to wait until data is available or until the timeout occurs. Only call recv() when data is actually available. To be safe, we also set the socket to non-blocking mode to guarantee that recv() will never block indefinitely. select() can also be used to wait on more than one socket at a time.

import select

mysocket.setblocking(0)

ready = select.select([mysocket], [], [], timeout_in_seconds)
if ready[0]:
    data = mysocket.recv(4096)

If you have a lot of open file descriptors, poll() is a more efficient alternative to select().

Another option is to set a timeout for all operations on the socket using socket.settimeout(), but I see that you've explicitly rejected that solution in another answer.

We shall get the long value by using Number reference.

public static long toLong(Number number){
    return number.longValue();
}

It works for all number types, here is a test:

public static void testToLong() throws Exception {
    assertEquals(0l, toLong(0));   // an int
    assertEquals(0l, toLong((short)0)); // a short
    assertEquals(0l, toLong(0l)); // a long
    assertEquals(0l, toLong((long) 0)); // another long
    assertEquals(0l, toLong(0.0f));  // a float
    assertEquals(0l, toLong(0.0));  // a double

}

you can set this in catalina.sh as CATALINA_OPTS=-Xms512m -Xmx512m

Open your tomcat-dir/bin/catalina.sh file and add following line anywhere -

CATALINA_OPTS="$CATALINA_OPTS -Xms1024m -Xmx3024m"

and restart your tomcat

Use a Temp Table or a Table variable, e.g.

select 'A' as [value]
into #tmp
union
select 'B'
union 
select 'C'

and then

SELECT   
blah 
FROM    foo 
WHERE   myField IN (select [value] from #tmp) 

or

SELECT   
f.blah 
FROM foo f INNER JOIN #tmp t ON f.myField = t.[value]

Simply you can use $state.transitionTo instead of $state.go . $state.go calls $state.transitionTo internally but automatically sets options to { location: true, inherit: true, relative: $state.$current, notify: true } . You can call $state.transitionTo and set notify: false . For example:

$state.go('.detail', {id: newId}) 

can be replaced by

$state.transitionTo('.detail', {id: newId}, {
    location: true,
    inherit: true,
    relative: $state.$current,
    notify: false
})

Edit: As suggested by fracz it can simply be:

$state.go('.detail', {id: newId}, {notify: false}) 

Since this is one of the top search results for questions related to this I felt it was worth mentioning how you can make this work with Kendo().DropDownListFor() as well.

Everything is the same as with OnaBai's post except for how you select the item based off of its text and your selector.

To do that you would swap out dataItem.symbol for dataItem.[DataTextFieldName]. Whatever model field you used for .DataTextField() is what you will be comparing against.

@(Html.Kendo().DropDownListFor(model => model.Status.StatusId)
    .Name("Status.StatusId")
    .DataTextField("StatusName")
    .DataValueField("StatusId")
    .BindTo(...)
)

//So that your ViewModel gets bound properly on the post, naming is a bit 
//different and as such you need to replace the periods with underscores
var ddl = $('#Status_StatusId').data('kendoDropDownList');    

ddl.select(function(dataItem) {
    return dataItem.StatusName === "Active";
});

I encountered this problem too and what solved it has nothing to do with Facebook but the prior script I included that was in bad form

<script type="text/javascript" src="js/my_script.js" />

I changed it to

<script type="text/javascript" src="js/my_script.js"></script>

And it works...

Weew... hopefully my experience can help others stuck in this that has done almost about everything but still can't get it to work...

Oh Boy... ^^

It can be as follows:

UPDATE A 
SET A.`id` = (SELECT id from B WHERE A.title = B.title)

I have changed the length of value from varchar(255) to varchar(25) to all varchar columns and i get the solution.

Many programming language optimize the switch statement so that it is much faster than a standard if-else if structure provided the cases are compiler constants. Many languages use a jump table or indexed branch table to optimize switch statements. Wikipedia has a good discussion of the switch statement. Also, here is a discussion of switch optimization in C.

One thing to note is that switch statements can be abused and, depending on the case, it may be preferable to use polymorphism instead of switch statements. See here for an example.

If you are having an issue retrieving the password using the keychain wrapper, use this code:

NSData *pass =[keychain objectForKey:(__bridge id)(kSecValueData)];
NSString *passworddecoded = [[NSString alloc] initWithData:pass
                                           encoding:NSUTF8StringEncoding];

Without you providing any specific error message, it's hard to give specific suggestions.

However, I was using the same example and was getting a permissions exception on File.OpenWrite - using the localFileName variable, because using Path.GetFile was pointing to a location that obviously would not have permissions for opening a file > C:\ProgramFiles\IIS(Express)\filename.doc

I found that using System.IO.Path.GetFileName is not correct, use System.IO.Path.GetFullPath instead, point to your file starting with "C:\..."

Also open your solution in FileExplorer and grant permissions to asp.net for the file or any folders holding the file. I was able to download my file at that point.

I posted an answer to this already when someone else asked the same question (see How to bring back "Browser mode" in IE11?).

Read my answer there for a fuller explaination, but in short:

• They removed it deliberately, because compat mode is not actually really very good for testing compatibility.

• If you really want to test for compatibility with any given version of IE, you need to test in a real copy of that IE version. MS provide free VMs on http://modern.ie/ for you to use for this purpose.

• The only way to get compat mode in IE11 is to set the X-UA-Compatible header. When you have this and the site defaults to compat mode, you will be able to set the mode in dev tools, but only between edge or the specified compat mode; other modes will still not be available.

Just for the fun, I'm offering an alternative solution using jOOQ and Java 8. Instead of using jOOQ, you could be using any other API that maps JDBC ResultSet to List, such as Spring JDBC or Apache DbUtils, or write your own ResultSetIterator:

jOOQ 3.8 or less

List<Object> list =
DSL.using(connection)
   .fetch("SELECT col1, col2, col3, ...")
   .stream()
   .flatMap(r -> Arrays.stream(r.intoArray()))
   .collect(Collectors.toList());

jOOQ 3.9

List<Object> list =
DSL.using(connection)
   .fetch("SELECT col1, col2, col3, ...")
   .stream()
   .flatMap(Record::intoStream)
   .collect(Collectors.toList());

(Disclaimer, I work for the company behind jOOQ)

The eval is dangerous - you shouldn't execute user input.

If you have 2.6 or newer, use ast instead of eval:

>>> import ast
>>> ast.literal_eval('["A","B" ,"C" ," D"]')
["A", "B", "C", " D"]

Once you have that, strip the strings.

If you're on an older version of Python, you can get very close to what you want with a simple regular expression:

>>> x='[  "A",  " B", "C","D "]'
>>> re.findall(r'"\s*([^"]*?)\s*"', x)
['A', 'B', 'C', 'D']

This isn't as good as the ast solution, for example it doesn't correctly handle escaped quotes in strings. But it's simple, doesn't involve a dangerous eval, and might be good enough for your purpose if you're on an older Python without ast.

In the ListBox DoubleClick event get the selecteditem(s) member of the listbox, and there you are.

void ListBox1DoubleClick(object sender, EventArgs e)
    {
        MessageBox.Show(string.Format("SelectedItem:\n{0}",listBox1.SelectedItem.ToString()));
    }

Have you thinked about using instanceof ? Like, say

if(myObject instanceof Collection) {
     Collection myCollection = (Collection) myObject;

Although not that pure OOP style, it is however largely used for so-called "type escalation".

First of all, when you create ob1 then constructor is called and it starts execution. At that time t.start() also runs in separate thread. Remember when a new thread is created, it runs parallely to main thread. And thats why main start execution again with next statement.

And Join() statement is used to prevent the child thread from becoming orphan. Means if you did'nt call join() in your main class, then main thread will exit after its execution and child thread will be still there executing the statements. Join() will wait until all child thread complete its execution and then only main method will exit.

Go through this article, helps a lot.

If you want to keep the database between uninstalls you have to put it on the SD Card. This is the only place that won't be deleted at the moment your app is deleted. But in return it can be deleted by the user every time.

If you put your DB on the SD Card you can't use the SQLiteOpenHelper anymore, but you can use the source and the architecture of this class to get some ideas on how to implement the creation, updating and opening of a databse.

css:

header.sticky {
  font-size: 24px;
  line-height: 48px;
  height: 48px;
  background: #efc47D;
  text-align: left;
  padding-left: 20px;
}

JS:

$(window).scroll(function() {
 if ($(this).scrollTop() > 100){  
    $('header').addClass("sticky");
  }
  else{
    $('header').removeClass("sticky");
  }
});

If you are using firestore (and not just storing the timestamp as a string) a date field in a document will return a Timestamp. The Timestamp object contains a toDate() method.

Using timeago you can create a relative time quite simply:

_ago(Timestamp t) {
  return timeago.format(t.toDate(), 'en_short');
}

build() {
  return  Text(_ago(document['mytimestamp'])));
}

Make sure to set _firestore.settings(timestampsInSnapshotsEnabled: true); to return a Timestamp instead of a Date object.

If you generally use constructor-injection and don't want to switch to property-injection then Spring's lookup-method-injection will let one bean lazily lookup the other and hence workaround the cyclic dependency. See here: http://docs.spring.io/spring/docs/1.2.9/reference/beans.html#d0e1161

This simple formula should work. Give the element whose text will contain a tab the following CSS property: white-space:pre. Otherwise your html may not render tabs at all. Then, wherever you want to have a tab in your text, type 	.

Since you didn't mention CSS, if you want to do this without a CSS file, just use

<tag-name style="white-space:pre">text in element&#9;more text</tag-name>

in your HTML.

Make a bat file with the following in it:

copy /y C:\temp\log1k.txt C:\temp\log1k_copied.txt

However, I think there are issues if there are spaces in your directory names. Notice this was copied to the same directory, but that doesn't matter. If you want to see how it runs, make another bat file that calls the first and outputs to a log:

C:\temp\test.bat > C:\temp\test.log

(assuming the first bat file was called test.bat and was located in that directory)

My shortened solution that works with unhandled areas, controllers and actions:

1. Create a view 404.cshtml.

2. Create a base class for your controllers:

   public class Controller : System.Web.Mvc.Controller
   {
       protected override void HandleUnknownAction(string actionName)
       {
           Http404().ExecuteResult(ControllerContext);
       }
   
       protected virtual ViewResult Http404()
       {
           Response.StatusCode = (int)HttpStatusCode.NotFound;
           return View("404");
       }
   }
   

3. Create a custom controller factory returning your base controller as a fallback:

   public class ControllerFactory : DefaultControllerFactory
   {
       protected override IController GetControllerInstance(RequestContext requestContext, Type controllerType)
       {
           if (controllerType != null)
               return base.GetControllerInstance(requestContext, controllerType);
   
           return new Controller();
       }
   }
   

4. Add to Application_Start() the following line:

   ControllerBuilder.Current.SetControllerFactory(typeof(ControllerFactory));
   

this works for me:

bool hasColumnName = reader.GetSchemaTable().AsEnumerable().Any(c => c["ColumnName"] == "YOUR_COLUMN_NAME");

For anyone having the problem of the API being called more than once while downloading a fairly large file using the method in the accepted answer, please set response buffering to true System.Web.HttpContext.Current.Response.Buffer = true;

This makes sure that the entire binary content is buffered on the server side before it is sent to the client. Otherwise you will see multiple request being sent to the controller and if you do not handle it properly, the file will become corrupt.

To DELETE, without changing the references, you should first delete or otherwise alter (in a manner suitable for your purposes) all relevant rows in other tables.

To TRUNCATE you must remove the references. TRUNCATE is a DDL statement (comparable to CREATE and DROP) not a DML statement (like INSERT and DELETE) and doesn't cause triggers, whether explicit or those associated with references and other constraints, to be fired. Because of this, the database could be put into an inconsistent state if TRUNCATE was allowed on tables with references. This was a rule when TRUNCATE was an extension to the standard used by some systems, and is mandated by the the standard, now that it has been added.

you can simply do:

In[17]:df['combined']=df['bar'].astype(str)+'_'+df['foo']+'_'+df['new']

In[17]:df
Out[18]: 
   bar foo     new    combined
0    1   a   apple   1_a_apple
1    2   b  banana  2_b_banana
2    3   c    pear    3_c_pear

Toolbar customization can done by following ways

write button and textViews code inside toolbar as shown below

<android.support.v7.widget.Toolbar
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/app_bar"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    >

    <Button
      android:layout_width="wrap_content"
        android:layout_height="@dimen/btn_height_small"
        android:text="Departure"
        android:layout_gravity="right"
        />
</android.support.v7.widget.Toolbar>

Other way is to use item menu as shown below

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.menu_main, menu);
    return true;
}

The first step is to make P2 reference P1 by doing the following

• Right Click on the project and select "Add Reference"
• Go to the Projects Tab
• Select P1 and hit OK

Next you'll need to make sure that the classes in P1 are accessible to P2. The easiest way is to make them public.

public class MyType { ... }

Now you should be able to use them in P2 via their fully qualified name. Assuming the namespace of P1 is Project1 then the following would work

Project1.MyType obj = new Project1.MyType();

The preferred way though is to add a using for Project1 so you can use the types without qualification

using Project1;
...

public void Example() {
  MyType obj = new MyType();
}

The original checked attribute (HTML 4 and before) did not require a value on it - if it existed, the element was "checked", if not, it wasn't.

This, however is not valid for XHTML that followed HTML 4.

The standard proposed to use checked="checked" as a condition for true - so both ways you posted end up doing the same thing.

It really doesn't matter which one you use - use the one that makes most sense to you and stick to it (or agree with your team which way to go).

$http_name_of_the_header_key

i.e if you have origin = domain.com in header, you can use $http_origin to get "domain.com"

In nginx does support arbitrary request header field. In the above example last part of a variable name is the field name converted to lower case with dashes replaced by underscores

Reference doc here: http://nginx.org/en/docs/http/ngx_http_core_module.html#var_http_

For your example the variable would be $http_my_custom_header.

I don't know if this would fit what you are doing, but as a quick fix I would "wrap" the http content into an https script. For instance, on your page that is served through https i would introduce an iframe that would replace your rss feed and in the src attr of the iframe put a url of a script on your server that captures the feed and outputs the html. the script is reading the feed through http and outputs it through https (thus "wrapping")

Just a thought

Here's a cleaner, more "plug-and-play", version of @Nagasaki45's answer. Unlike many other answers here, it works properly with strings of different lengths. It achieves this by clearing the line with just as many spaces as the length of the last line printed print. Will also work on Windows.

def print_statusline(msg: str):
    last_msg_length = len(print_statusline.last_msg) if hasattr(print_statusline, 'last_msg') else 0
    print(' ' * last_msg_length, end='\r')
    print(msg, end='\r')
    sys.stdout.flush()  # Some say they needed this, I didn't.
    print_statusline.last_msg = msg

Usage

Simply use it like this:

for msg in ["Initializing...", "Initialization successful!"]:
    print_statusline(msg)
    time.sleep(1)

This small test shows that lines get cleared properly, even for different lengths:

for i in range(9, 0, -1):
    print_statusline("{}".format(i) * i)
    time.sleep(0.5)

You really want to do this

flog.write("\nCompany Name: "+ pCompanyName.encode('utf-8'))

This is the "encode late" strategy described in this unicode presentation (slides 32 through 35).

I have the same problem, but you know why? because I didn't put .txt in the end of my File and so it was File not a textFile, you shoud do just two things:

1. Put your Text File in the Root Directory (e.x if you have a project called HelloWorld, just right-click on the HelloWorld file in the package Directory and create File
2. Save as that File with any name that you want but with a .txt in the end of that I guess your problem is solved, but I write it to other peoples know that. Thanks.

I'd advise against a simple regular expression approach to this problem. There are too many words that are substrings of other unrelated words, and you'll probably drive yourself crazy trying to overadapt the simpler solutions already provided.

You'll want at least a naive stemming algorithm (try the Porter stemmer; there's available, free code in most languages) to process text first. Keep this processed text and the preprocessed text in two separate space-split arrays. Make sure each non-alphabetical character also gets its own index in this array. Whatever list of words you're filtering, stem them also.

The next step would be to find the array indices which match to your list of stemmed 'stop' words. Remove those from the unprocessed array, and then rejoin on spaces.

This is only slightly more complicated, but will be much more reliable an approach. If you've got any doubts on the value of a more NLP-oriented approach, you might want to do some research into clbuttic mistakes.

you have a lot of answers in the post

var d1 = new Date (),
d2 = new Date ( d1 );
d2.setMinutes ( d1.getMinutes() + 20 );
alert ( d2 );

Here is how you can print without using native function.

function pretty(ob, lvl = 0) {

  let temp = [];

  if(typeof ob === "object"){
    for(let x in ob) {
      if(ob.hasOwnProperty(x)) {
        temp.push( getTabs(lvl+1) + x + ":" + pretty(ob[x], lvl+1) );
      }
    }
    return "{\n"+ temp.join(",\n") +"\n" + getTabs(lvl) + "}";
  }
  else {
    return ob;
  }

}

function getTabs(n) {
  let c = 0, res = "";
  while(c++ < n)
    res+="\t";
  return res;
}

let obj = {a: {b: 2}, x: {y: 3}};
console.log(pretty(obj));

/*
  {
    a: {
      b: 2
    },
    x: {
      y: 3
    }
  }
*/

It is because one or all of the maven dependencies got corrupted. Just delete corrupted dependencies or all the maven local dependencies and restart the eclipse and update project.

Install brew or apt-get is also not easy for me so I downloaded mysql via: https://dev.mysql.com/downloads/connector/python/, installed it. So I can find mysql_config int this directory: /usr/local/mysql/bin

the next step is:

1. export PATH=$PATH:/usr/local/mysql/bin
2. pip install MySQL-python==1.2.5

    UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 100, 30)];

Based up the OP's original request to be able to called a stored proc like this...

using (Entities context = new Entities())
{
    context.MyStoreadProcedure(Parameters); 
}

Mindless passenger has a project that allows you to call a stored proc from entity frame work like this....

using (testentities te = new testentities())
{
    //-------------------------------------------------------------
    // Simple stored proc
    //-------------------------------------------------------------
    var parms1 = new testone() { inparm = "abcd" };
    var results1 = te.CallStoredProc<testone>(te.testoneproc, parms1);
    var r1 = results1.ToList<TestOneResultSet>();
}

... and I am working on a stored procedure framework (here) which you can call like in one of my test methods shown below...

[TestClass]
public class TenantDataBasedTests : BaseIntegrationTest
{
    [TestMethod]
    public void GetTenantForName_ReturnsOneRecord()
    {
        // ARRANGE
        const int expectedCount = 1;
        const string expectedName = "Me";

        // Build the paraemeters object
        var parameters = new GetTenantForTenantNameParameters
        {
            TenantName = expectedName
        };

        // get an instance of the stored procedure passing the parameters
        var procedure = new GetTenantForTenantNameProcedure(parameters);

        // Initialise the procedure name and schema from procedure attributes
        procedure.InitializeFromAttributes();

        // Add some tenants to context so we have something for the procedure to return!
        AddTenentsToContext(Context);

        // ACT
        // Get the results by calling the stored procedure from the context extention method 
        var results = Context.ExecuteStoredProcedure(procedure);

        // ASSERT
        Assert.AreEqual(expectedCount, results.Count);
    }
}

internal class GetTenantForTenantNameParameters
{
    [Name("TenantName")]
    [Size(100)]
    [ParameterDbType(SqlDbType.VarChar)]
    public string TenantName { get; set; }
}

[Schema("app")]
[Name("Tenant_GetForTenantName")]
internal class GetTenantForTenantNameProcedure
    : StoredProcedureBase<TenantResultRow, GetTenantForTenantNameParameters>
{
    public GetTenantForTenantNameProcedure(
        GetTenantForTenantNameParameters parameters)
        : base(parameters)
    {
    }
}

If either of those two approaches are any good?

Interestingly putting <httpCookies httpOnlyCookies="false"/> doesn't seem to disable httpOnlyCookies in ASP.NET 2.0. Check this article about SessionID and Login Problems With ASP .NET 2.0.

Looks like Microsoft took the decision to not allow you to disable it from the web.config. Check this post on forums.asp.net

A SELECT INTO statement will throw an error if it returns anything other than 1 row. If it returns 0 rows, you'll get a no_data_found exception. If it returns more than 1 row, you'll get a too_many_rows exception. Unless you know that there will always be exactly 1 employee with a salary greater than 3000, you do not want a SELECT INTO statement here.

Most likely, you want to use a cursor to iterate over (potentially) multiple rows of data (I'm also assuming that you intended to do a proper join between the two tables rather than doing a Cartesian product so I'm assuming that there is a departmentID column in both tables)

BEGIN
  FOR rec IN (SELECT EMPLOYEE.EMPID, 
                     EMPLOYEE.ENAME, 
                     EMPLOYEE.DESIGNATION, 
                     EMPLOYEE.SALARY,  
                     DEPARTMENT.DEPT_NAME 
                FROM EMPLOYEE, 
                     DEPARTMENT 
               WHERE employee.departmentID = department.departmentID
                 AND EMPLOYEE.SALARY > 3000)
  LOOP
    DBMS_OUTPUT.PUT_LINE ('Employee Nnumber: ' || rec.EMPID);
    DBMS_OUTPUT.PUT_LINE ('---------------------------------------------------');
    DBMS_OUTPUT.PUT_LINE ('Employee Name: ' || rec.ENAME);
    DBMS_OUTPUT.PUT_LINE ('---------------------------------------------------');
    DBMS_OUTPUT.PUT_LINE ('Employee Designation: ' || rec.DESIGNATION);
    DBMS_OUTPUT.PUT_LINE ('----------------------------------------------------');
    DBMS_OUTPUT.PUT_LINE ('Employee Salary: ' || rec.SALARY);
    DBMS_OUTPUT.PUT_LINE ('----------------------------------------------------');
    DBMS_OUTPUT.PUT_LINE ('Employee Department: ' || rec.DEPT_NAME);
  END LOOP;
END;

I'm assuming that you are just learning PL/SQL as well. In real code, you'd never use dbms_output like this and would not depend on anyone seeing data that you write to the dbms_output buffer.

      1- delete .gradle folder in the root directory of the app
      2- invalidate cache and restart 

In addition to Ishan's answer, if you want to draw programatically without user interaction, you can edit the class just a little like this.

public class DrawingCanvas extends View {

private Paint mPaint;
private Path mPath;
private boolean isUserInteractionEnabled = false;

public DrawingCanvas(Context context, AttributeSet attrs) {
    super(context, attrs);
    mPaint = new Paint();
    mPaint.setColor(Color.RED);
    mPaint.setStyle(Paint.Style.STROKE);
    mPaint.setStrokeJoin(Paint.Join.ROUND);
    mPaint.setStrokeCap(Paint.Cap.ROUND);
    mPaint.setStrokeWidth(10);
    mPath = new Path();

@Override

    canvas.drawPath(mPath, mPaint);
    super.onDraw(canvas);

@Override

    if (isUserInteractionEnabled) {
        switch (event.getAction()) {
            case MotionEvent.ACTION_DOWN:
                mPath.moveTo(event.getX(), event.getY());
                break;
            case MotionEvent.ACTION_MOVE:
                mPath.lineTo(event.getX(), event.getY());
                invalidate();
                break;
            case MotionEvent.ACTION_UP:
                break;
        }
    }

    return true;
}

public void moveCursorTo(float x, float y) {
    mPath.moveTo(x, y);
}

public void makeLine(float toX, float toY) {
    mPath.lineTo(toX, toY);
}

public void setUserInteractionEnabled(boolean userInteractionEnabled) {
    isUserInteractionEnabled = userInteractionEnabled;
}
}

And then use it like

drawingCanvas.setUserInteractionEnabled(true) // to enable user interaction
drawingCanvas.setUserInteractionEnabled(true) // to disable user interaction

To Draw programatically

drawingCanvas.moveCursorTo(70f, 70f) // Move the cursor (Define starting point)
drawingCanvas.makeLine(200f, 200f) // End point (To where you need to draw)

Noticing that user 42-'s perfect approach {
* "do while" = "repeat until not"
* The code equivalence:

do while (condition) # in other language
..statements..
endo

repeat{ # in R
  ..statements..
  if(! condition){ break } # Negation is crucial here!
}

} did not receive enough attention from the others, I'll emphasize and bring forward his approach via a concrete example. If one does not negate the condition in do-while (via ! or by taking negation), then distorted situations (1. value persistence 2. infinite loop) exist depending on the course of the code.

In Gauss:

proc(0)=printvalues(y);
DO WHILE y < 5;    
y+1;
 y=y+1;
ENDO;
ENDP;
printvalues(0); @ run selected code via F4 to get the following @
       1.0000000 
       2.0000000 
       3.0000000 
       4.0000000 
       5.0000000 

In R:

printvalues <- function(y) {
repeat {
 y=y+1;
print(y)
if (! (y < 5) ) {break}   # Negation is crucial here!
}
}
printvalues(0)
# [1] 1
# [1] 2
# [1] 3
# [1] 4
# [1] 5

I still insist that without the negation of the condition in do-while, Salcedo's answer is wrong. One can check this via removing negation symbol in the above code.

There are several problems in your code.

First the big ones:

1. You are creating a new figure and a new axes in every iteration of your loop ? put fig = plt.figure and ax = fig.add_subplot(1,1,1) outside of the loop.

2. Don't use the Locators. Call the functions ax.set_xticks() and ax.grid() with the correct keywords.

3. With plt.axes() you are creating a new axes again. Use ax.set_aspect('equal').

The minor things: You should not mix the MATLAB-like syntax like plt.axis() with the objective syntax. Use ax.set_xlim(a,b) and ax.set_ylim(a,b)

This should be a working minimal example:

import numpy as np
import matplotlib.pyplot as plt

fig = plt.figure()
ax = fig.add_subplot(1, 1, 1)

# Major ticks every 20, minor ticks every 5
major_ticks = np.arange(0, 101, 20)
minor_ticks = np.arange(0, 101, 5)

ax.set_xticks(major_ticks)
ax.set_xticks(minor_ticks, minor=True)
ax.set_yticks(major_ticks)
ax.set_yticks(minor_ticks, minor=True)

# And a corresponding grid
ax.grid(which='both')

# Or if you want different settings for the grids:
ax.grid(which='minor', alpha=0.2)
ax.grid(which='major', alpha=0.5)

plt.show()

Output is this:

This is equivalent to the path of the script:

%~dp0

This uses the batch parameter extension syntax. Parameter 0 is always the script itself.

If your script is stored at C:\example\script.bat, then %~dp0 evaluates to C:\example\.

ss64.com has more information about the parameter extension syntax. Here is the relevant excerpt:

You can get the value of any parameter using a % followed by it's numerical position on the command line.

[...]

When a parameter is used to supply a filename then the following extended syntax can be applied:

[...]

%~d1 Expand %1 to a Drive letter only - C:

[...]

%~p1 Expand %1 to a Path only e.g. \utils\ this includes a trailing \ which may be interpreted as an escape character by some commands.

[...]

The modifiers above can be combined:

%~dp1 Expand %1 to a drive letter and path only

[...]

You can get the pathname of the batch script itself with %0, parameter extensions can be applied to this so %~dp0 will return the Drive and Path to the batch script e.g. W:\scripts\

If not using C++14, then I find below the simplest solution.

#define METHOD(NAME, ...) auto NAME __VA_ARGS__ -> decltype(m_T.r##NAME) { return m_T.r##NAME; }
template<typename T>
struct Reverse
{
  T& m_T;

  METHOD(begin());
  METHOD(end());
  METHOD(begin(), const);
  METHOD(end(), const);
};
#undef METHOD

template<typename T>
Reverse<T> MakeReverse (T& t) { return Reverse<T>{t}; }

Demo.
It doesn't work for the containers/data-types (like array), which doesn't have begin/rbegin, end/rend functions.

I used this code to show the dialog at the bottom of the screen:

Dialog dlg = <code to create custom dialog>;

Window window = dlg.getWindow();
WindowManager.LayoutParams wlp = window.getAttributes();

wlp.gravity = Gravity.BOTTOM;
wlp.flags &= ~WindowManager.LayoutParams.FLAG_DIM_BEHIND;
window.setAttributes(wlp);

This code also prevents android from dimming the background of the dialog, if you need it. You should be able to change the gravity parameter to move the dialog about

private void showPictureialog() {
    final Dialog dialog = new Dialog(this,
            android.R.style.Theme_Translucent_NoTitleBar);

    // Setting dialogview
    Window window = dialog.getWindow();
    window.setGravity(Gravity.CENTER);

    window.setLayout(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT);
    dialog.setTitle(null);
    dialog.setContentView(R.layout.selectpic_dialog);
    dialog.setCancelable(true);

    dialog.show();
}

you can customize you dialog based on gravity and layout parameters change gravity and layout parameter on the basis of your requirenment

Inspired by Eric's answer, here is my solution to this problem for selenium 3.7.0. Compared with the solution at http://tarunlalwani.com/post/reusing-existing-browser-session-selenium/, the advantage is that there won't be a blank browser window each time I connect to the existing session.

        self.capabilities = response['value']

To use it:

if use_existing_session:
    browser = AttachableWebDriver(command_executor=('http://%s:4444/wd/hub' % ip),
                                  desired_capabilities=(DesiredCapabilities.INTERNETEXPLORER),

else:
    browser = AttachableWebDriver(command_executor=('http://%s:4444/wd/hub' % ip),
                                  desired_capabilities=(DesiredCapabilities.INTERNETEXPLORER))
    self.logger.info('New session_id  : {}'.format(browser.session_id))

you can get the index via grep and colnames:

grep("B", colnames(df))
[1] 2

or use

grep("^B$", colnames(df))
[1] 2

to only get the columns called "B" without those who contain a B e.g. "ABC".

You can use mysql_real_escape_string. mysql_real_escape_string() does not escape % and _, so you should escape MySQL wildcards (% and _) separately.

In my case none of the above solutions worked. I solved by right clicking on the reference

System.Net.Http.Formatting

from Visual studio and setting the property Copy Local to true.

I hope this is useful somehow.

Escape with a double backslash

R treats backslashes as escape values for character constants. (... and so do regular expressions. Hence the need for two backslashes when supplying a character argument for a pattern. The first one isn't actually a character, but rather it makes the second one into a character.) You can see how they are processed using cat.

y <- "double quote: \", tab: \t, newline: \n, unicode point: \u20AC"
print(y)
## [1] "double quote: \", tab: \t, newline: \n, unicode point: €"
cat(y)
## double quote: ", tab:    , newline: 
## , unicode point: €

Further reading: Escaping a backslash with a backslash in R produces 2 backslashes in a string, not 1

To use special characters in a regular expression the simplest method is usually to escape them with a backslash, but as noted above, the backslash itself needs to be escaped.

grepl("\\[", "a[b")
## [1] TRUE

To match backslashes, you need to double escape, resulting in four backslashes.

grepl("\\\\", c("a\\b", "a\nb"))
## [1]  TRUE FALSE

The rebus package contains constants for each of the special characters to save you mistyping slashes.

library(rebus)
OPEN_BRACKET
## [1] "\\["
BACKSLASH
## [1] "\\\\"

For more examples see:

?SpecialCharacters

Your problem can be solved this way:

library(rebus)
grepl(OPEN_BRACKET, "a[b")

Form a character class

You can also wrap the special characters in square brackets to form a character class.

grepl("[?]", "a?b")
## [1] TRUE

Two of the special characters have special meaning inside character classes: \ and ^.

Backslash still needs to be escaped even if it is inside a character class.

grepl("[\\\\]", c("a\\b", "a\nb"))
## [1]  TRUE FALSE

Caret only needs to be escaped if it is directly after the opening square bracket.

grepl("[ ^]", "a^b")  # matches spaces as well.
## [1] TRUE
grepl("[\\^]", "a^b") 
## [1] TRUE

rebus also lets you form a character class.

char_class("?")
## <regex> [?]

Use a pre-existing character class

If you want to match all punctuation, you can use the [:punct:] character class.

grepl("[[:punct:]]", c("//", "[", "(", "{", "?", "^", "$"))
## [1] TRUE TRUE TRUE TRUE TRUE TRUE TRUE

stringi maps this to the Unicode General Category for punctuation, so its behaviour is slightly different.

stri_detect_regex(c("//", "[", "(", "{", "?", "^", "$"), "[[:punct:]]")
## [1]  TRUE  TRUE  TRUE  TRUE  TRUE FALSE FALSE

You can also use the cross-platform syntax for accessing a UGC.

stri_detect_regex(c("//", "[", "(", "{", "?", "^", "$"), "\\p{P}")
## [1]  TRUE  TRUE  TRUE  TRUE  TRUE FALSE FALSE

Use \Q \E escapes

Placing characters between \\Q and \\E makes the regular expression engine treat them literally rather than as regular expressions.

grepl("\\Q.\\E", "a.b")
## [1] TRUE

rebus lets you write literal blocks of regular expressions.

literal(".")
## <regex> \Q.\E

Don't use regular expressions

Regular expressions are not always the answer. If you want to match a fixed string then you can do, for example:

grepl("[", "a[b", fixed = TRUE)
stringr::str_detect("a[b", fixed("["))
stringi::stri_detect_fixed("a[b", "[")

Here's another way:

int length = 0;
while (!str.equals("")) {
    str = str.substring(1);
    ++length;
}

In the same spirit (although much less efficient):

String regex = "(?s)";
int length = 0;
while (!str.matches(regex)) {
    regex += ".";
    ++length;
}

Or even:

int length = 0;
while (!str.matches("(?s).{" + length + "}")) {
    ++length;
}

Your .vimrc file goes in your $HOME directory. In *nix, cd ~; vim .vimrc. The commands in the .vimrc are the same as you type in ex-mode in vim, only without the leading colon, so colo evening would suffice. Comments in the .vimrc are indicated with a leading double-quote.

To see an example vimrc, open $VIMRUNTIME/vimrc_example.vim from within vim

:e $VIMRUNTIME/vimrc_example.vim

org.apache.commons.lang3.StringUtils.substring(s, -7) 

gives you the answer. It returns the input if it is shorter than 7, and null if s == null. It never throws an exception.

See https://commons.apache.org/proper/commons-lang/apidocs/org/apache/commons/lang3/StringUtils.html#substring-java.lang.String-int-int-

You probably should not use your own function here. Use find() from STL.

Example:

list L;
L.push_back(3);
L.push_back(1);
L.push_back(7);

list::iterator result = find(L.begin(), L.end(), 7);
assert(result == L.end() || *result == 7);

In Rails 3, I don't know anything fancier. However, I'm not sure if you're aware, your not equal condition does not match for (user_id) NULL values. If you want that, you'll have to do something like this:

GroupUser.where("user_id != ? OR user_id IS NULL", me)

In MacOS Mojave, the location is:

/Library/Java/JavaVirtualMachines/jdk1.8.0_192.jdk/Contents/Home/jre/lib/security/cacerts 

If using sdkman to manage java versions, the cacerts is in

~/.sdkman/candidates/java/current/jre/lib/security

Here is:

var array : [String] = ["One", "Two", "Three"]
let userDefault = UserDefaults.standard
// set
userDefault.set(array, forKey: "array")
// retrieve 
if let fetchArray = userDefault.array(forKey: "array") as? [String] {
    // code 
}

This is an easy way for any format. Just change it to required format string

XMLGregorianCalendar gregFmt = DatatypeFactory.newInstance().newXMLGregorianCalendar(new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss").format(new Date()));
System.out.println(gregFmt);

The <select> element is generated by the application and styling is not part of the CSS/HTML spec.

You would have to fake it with your own DIV and overlay it on top of the existing one, or build your own control emulating the same functionality.

You can find all the details here:

• IDEA-170117 "objc: Class JavaLaunchHelper is implemented in both ..." warning in Run consoles

It's the old bug in Java on Mac that got triggered by the Java Agent being used by the IDE when starting the app. This message is harmless and is safe to ignore. Oracle developer's comment:

The message is benign, there is no negative impact from this problem since both copies of that class are identical (compiled from the exact same source). It is purely a cosmetic issue.

The problem is fixed in Java 9 and in Java 8 update 152.

If it annoys you or affects your apps in any way (it shouldn't), the workaround for IntelliJ IDEA is to disable idea_rt launcher agent by adding idea.no.launcher=true into idea.properties (Help | Edit Custom Properties...). The workaround will take effect on the next restart of the IDE.

I don't recommend disabling IntelliJ IDEA launcher agent, though. It's used for such features as graceful shutdown (Exit button), thread dumps, workarounds a problem with too long command line exceeding OS limits, etc. Losing these features just for the sake of hiding the harmless message is probably not worth it, but it's up to you.

Add the s modifier to your regex to cause . to match newlines:

$string =~ /(START)(.+?)(END)/s;

You can use either,

int i = Convert.ToInt32(TextBoxD1.Text);

or

int i = int.Parse(TextBoxD1.Text);

arguments.callee.toString();

seems to be right for your needs.

I think what are attempting is semantically same as a radio button when 1 is when one of the options is selected and 0 is the other option.

I suggest using the radio button provided by Android by default.

Here is how to use it- http://www.mkyong.com/android/android-radio-buttons-example/

and the android documentation is here-

http://developer.android.com/guide/topics/ui/controls/radiobutton.html

Thanks.

Use a packet sniffer like Wireshark to look at what happens. You need to see a SYN-flagged packet outgoing, a SYN+ACK-flagged incoming and then a ACK-flagged outgoing. After that, the port is considered open on the local side.

If you only see the first packet and the error message comes after several seconds of waiting, the other side is not answering at all (like in: unplugged cable, overloaded server, misguided packet was discarded) and your local network stack aborts the connection attempt. If you see RST packets, the host actually denies the connection. If you see "ICMP Port unreachable" or host unreachable packets, a firewall or the target host inform you of the port actually being closed.

Of course you cannot expect the service to be available at all times (consider all the points of failure in between you and the data), so you should try again later.

this worked for me:

ALTER TABLE [Table] 
Alter COLUMN [Column] VARCHAR(50) not null;

You can pass variable on the command line via --extra-vars "name=value". Sudo password variable is ansible_sudo_pass. So your command would look like:

ansible-playbook playbook.yml -i inventory.ini --user=username \
                              --extra-vars "ansible_sudo_pass=yourPassword"

Update 2017: Ansible 2.2.1.0 now uses var ansible_become_pass. Either seems to work.

For someone who is new to IPC and Named Pipes, I found the following NuGet package to be a great help.

GitHub: Named Pipe Wrapper for .NET 4.0

To use first install the package:

PS> Install-Package NamedPipeWrapper

Then an example server (copied from the link):

var server = new NamedPipeServer<SomeClass>("MyServerPipe");
server.ClientConnected += delegate(NamedPipeConnection<SomeClass> conn)
    {
        Console.WriteLine("Client {0} is now connected!", conn.Id);
        conn.PushMessage(new SomeClass { Text: "Welcome!" });
    };

server.ClientMessage += delegate(NamedPipeConnection<SomeClass> conn, SomeClass message)
    {
        Console.WriteLine("Client {0} says: {1}", conn.Id, message.Text);
    };

server.Start();

Example client:

var client = new NamedPipeClient<SomeClass>("MyServerPipe");
client.ServerMessage += delegate(NamedPipeConnection<SomeClass> conn, SomeClass message)
    {
        Console.WriteLine("Server says: {0}", message.Text);
    };

client.Start();

Best thing about it for me is that unlike the accepted answer here it supports multiple clients talking to a single server.

If you just want to get rid of the error, you can also delete this line in bootstrap.css:

/*# sourceMappingURL=bootstrap.css.map */

if you want to use it in all of your classes you can use:

public var yourVariable = "something"

if you want to use just in one class you can use :

var yourVariable = "something"

Select * from table where date > 'Today's date(mm/dd/yyyy)'

You can also add time in the single quotes(00:00:00AM)

For example:

Select * from Receipts where Sales_date > '08/28/2014 11:59:59PM'

@Ric Jafe's solution is what worked for me.

This is exactly what I was looking for. A way to push it through for research test code. Nothing fancy. Yeah I know that that's what they all say :) The various maven plugin solutions seem to be overkill for my purposes. I have some jars that were given to me as 3rd party libs with a pom file. I want it to compile/run quickly. This solution which I trivially adapted to python worked wonders for me. Cut and pasted into my pom. Python/Perl code for this task is in this Q&A: Can I add jars to maven 2 build classpath without installing them?

def AddJars(jarList):
  s1 = ''
  for elem in jarList:
   s1+= """
     <dependency>
        <groupId>local.dummy</groupId>
        <artifactId>%s</artifactId>
        <version>0.0.1</version>
        <scope>system</scope>
        <systemPath>${project.basedir}/manual_jars/%s</systemPath>
     </dependency>\n"""%(elem, elem)
  return s1

Another way I haven't seen listed yet is to set your sentinel value ahead of time. This method takes advantage of Python's lazy evaluation, in which you don't always have to provide an else statement. Example:

startingpoint = 'blah'
if len(sys.argv) >= 2:
  startingpoint = sys.argv[1]

Or if you're going syntax CRAZY you could use Python's ternary operator:

startingpoint = sys.argv[1] if len(sys.argv) >= 2 else 'blah'

The built-in getopts command is still, AFAIK, limited to single-character options only.

There is (or used to be) an external program getopt that would reorganize a set of options such that it was easier to parse. You could adapt that design to handle long options too. Example usage:

aflag=no
bflag=no
flist=""
set -- $(getopt abf: "$@")
while [ $# -gt 0 ]
do
    case "$1" in
    (-a) aflag=yes;;
    (-b) bflag=yes;;
    (-f) flist="$flist $2"; shift;;
    (--) shift; break;;
    (-*) echo "$0: error - unrecognized option $1" 1>&2; exit 1;;
    (*)  break;;
    esac
    shift
done

# Process remaining non-option arguments
...

You could use a similar scheme with a getoptlong command.

Note that the fundamental weakness with the external getopt program is the difficulty of handling arguments with spaces in them, and in preserving those spaces accurately. This is why the built-in getopts is superior, albeit limited by the fact it only handles single-letter options.

div1 {
    float: right;
} 
div2 {
    float: left;
}

This will work OK as long as you set clear: both for the element that separates this two column block.

a <- 1:120
b <- a[seq(1, length(a), 6)]

maybe you are having the same problem i had, my tablet has a SD card on it, in /mnt/sdcard and the sd card external was in /mnt/extcard, you can look it on the android file manager, going to your sd card and see the path to it.

Hope it helps.

1. Create an Activity SplashScreen.java

   public class SplashScreen extends Activity {
   protected boolean _active = true;
   protected int _splashTime = 3000; // time to display the splash screen in ms
   
   
   
   @Override
   public void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
       setContentView(R.layout.splashscreen);
   
       Thread splashTread = new Thread() {
           @Override
           public void run() {
               try {
                   int waited = 0;
                   while (_active && (waited < _splashTime)) {
                       sleep(100);
                       if (_active) {
                           waited += 100;
                       }
                   }
               } catch (Exception e) {
   
               } finally {
   
                   startActivity(new Intent(SplashScreen.this,
                           MainActivity.class));
                   finish();
               }
           };
                };
       splashTread.start();
   }
    }
   

2. splashscreen.xml will be like this

   <?xml version="1.0" encoding="utf-8"?>
   <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
     android:layout_width="600px" android:layout_height="1024px"
     android:background="#FF0000">
   </RelativeLayout> 
   

The methods are used for different things.

Thread.sleep(5000);   // Wait until the time has passed.

Object.wait();        // Wait until some other thread tells me to wake up.

Thread.sleep(n) can be interrupted, but Object.wait() must be notified. It's possible to specify the maximum time to wait: Object.wait(5000) so it would be possible to use wait to, er, sleep but then you have to bother with locks.

Neither of the methods uses the cpu while sleeping/waiting.

The methods are implemented using native code, using similar constructs but not in the same way.

Look for yourself: Is the source code of native methods available? The file /src/share/vm/prims/jvm.cpp is the starting point...

As a string, no. As an integer, %d.

Unless you count:

static char* enumStrings[] = { /* filler 0's to get to the first value, */
                               "enum0", "enum1", 
                               /* filler for hole in the middle: ,0 */
                               "enum2", "enum3", .... };

...

printf("The value is %s\n", enumStrings[thevalue]);

This won't work for something like an enum of bit masks. At that point, you need a hash table or some other more elaborate data structure.

Edit: A hacky way to do it would be to create a variable that keeps track of focus for every element you care about. So, if you care that 'myInput' lost focus, set a variable to it on focus.

<script type="text/javascript">
   var lastFocusedElement;
</script>
<input id="myInput" onFocus="lastFocusedElement=this;" />

Original Answer: You can pass 'this' to the function.

<input id="myInput" onblur="function(this){
   var theId = this.id; // will be 'myInput'
}" />

I had similar trouble in a venv on a mounted NTFS partition on linux with all the right permissions. Making sure pip ran with --ignore-installed solved it, i.e.:

python -m pip install --upgrade --ignore-installed

You could just search for the item you want to delete. It is really simple. Example:

    letters = ["a", "b", "c", "d", "e"]
    letters.remove(letters[1])
    print(*letters) # Used with a * to make it unpack you don't have to (Python 3.x or newer)

Output: a c d e

Let's evaluate the parsing of each:

http://jsfiddle.net/brandonscript/Y2dGv/

var json1 = '{}';
var json2 = '{"myCount": null}';
var json3 = '{"myCount": 0}';
var json4 = '{"myString": ""}';
var json5 = '{"myString": "null"}';
var json6 = '{"myArray": []}';

console.log(JSON.parse(json1)); // {}
console.log(JSON.parse(json2)); // {myCount: null}
console.log(JSON.parse(json3)); // {myCount: 0}
console.log(JSON.parse(json4)); // {myString: ""}
console.log(JSON.parse(json5)); // {myString: "null"}
console.log(JSON.parse(json6)); // {myArray: []}

The tl;dr here:

The fragment in the json2 variable is the way the JSON spec indicates null should be represented. But as always, it depends on what you're doing -- sometimes the "right" way to do it doesn't always work for your situation. Use your judgement and make an informed decision.

JSON1 {}

This returns an empty object. There is no data there, and it's only going to tell you that whatever key you're looking for (be it myCount or something else) is of type undefined.

JSON2 {"myCount": null}

In this case, myCount is actually defined, albeit its value is null. This is not the same as both "not undefined and not null", and if you were testing for one condition or the other, this might succeed whereas JSON1 would fail.

This is the definitive way to represent null per the JSON spec.

JSON3 {"myCount": 0}

In this case, myCount is 0. That's not the same as null, and it's not the same as false. If your conditional statement evaluates myCount > 0, then this might be worthwhile to have. Moreover, if you're running calculations based on the value here, 0 could be useful. If you're trying to test for null however, this is actually not going to work at all.

JSON4 {"myString": ""}

In this case, you're getting an empty string. Again, as with JSON2, it's defined, but it's empty. You could test for if (obj.myString == "") but you could not test for null or undefined.

JSON5 {"myString": "null"}

This is probably going to get you in trouble, because you're setting the string value to null; in this case, obj.myString == "null" however it is not == null.

JSON6 {"myArray": []}

This will tell you that your array myArray exists, but it's empty. This is useful if you're trying to perform a count or evaluation on myArray. For instance, say you wanted to evaluate the number of photos a user posted - you could do myArray.length and it would return 0: defined, but no photos posted.

The easisest thing to do is to wrap your code in a transaction, and then execute each batch of T-SQL code line by line.

For example,

Begin Transaction

         -Do some T-SQL queries here.

Rollback transaction -- OR commit transaction

If you want to incorporate error handling you can do so by using a TRY...CATCH BLOCK. Should an error occur you can then rollback the tranasction within the catch block.

For example:

USE AdventureWorks;
GO
BEGIN TRANSACTION;

BEGIN TRY
    -- Generate a constraint violation error.
    DELETE FROM Production.Product
    WHERE ProductID = 980;
END TRY
BEGIN CATCH
    SELECT 
        ERROR_NUMBER() AS ErrorNumber
        ,ERROR_SEVERITY() AS ErrorSeverity
        ,ERROR_STATE() AS ErrorState
        ,ERROR_PROCEDURE() AS ErrorProcedure
        ,ERROR_LINE() AS ErrorLine
        ,ERROR_MESSAGE() AS ErrorMessage;

    IF @@TRANCOUNT > 0
        ROLLBACK TRANSACTION;
END CATCH;

IF @@TRANCOUNT > 0
    COMMIT TRANSACTION;
GO

Hope this helps but please let me know if you need more details.

You may also want to check to make sure your not replacing an occurrence that has already been replaced. You can use a regular expression with negative lookahead to do this.

For example:

String str = "sdasdasa&adas&dasdasa";  
str = str.replaceAll("&(?!amp;)", "&");

This would result in the string "sdasdasa&adas&dasdasa".

The regex pattern "&(?!amp;)" basically says: Match any occurrence of '&' that is not followed by 'amp;'.

$sql="SELECT * FROM TABLE_NAME WHERE item_id=".$item_id;

$query=mysql_query($sql);

while($myrow=mysql_fetch_array($query)) {

echo   print_r($myrow,1);


}

select *
from Common c
where not exists (select t1.commonid from table1 t1 where t1.commonid = c.commonid)
and not exists (select t2.commonid from table2 t2 where t2.commonid = c.commonid)

This is universal code , no matter how your input is long but in same schema if there is : separator :)

var string = "firstName:name1, lastName:last1"; 
var pass = string.replace(',',':');
var arr = pass.split(':');
var empty = {};
arr.forEach(function(el,i){
  var b = i + 1, c = b/2, e = c.toString();
     if(e.indexOf('.') != -1 ) {
     empty[el] = arr[i+1];
  } 
}); 
  console.log(empty)

With PostgreSQL there are a number of date/time functions available, see here.

In your example, you could use:

SELECT * FROM myTable WHERE date_trunc('day', dt) = 'YYYY-MM-DD';

If you are running this query regularly, it is possible to create an index using the date_trunc function as well:

CREATE INDEX date_trunc_dt_idx ON myTable ( date_trunc('day', dt) );

One advantage of this is there is some more flexibility with timezones if required, for example:

CREATE INDEX date_trunc_dt_idx ON myTable ( date_trunc('day', dt at time zone 'Australia/Sydney') );
SELECT * FROM myTable WHERE date_trunc('day', dt at time zone 'Australia/Sydney') = 'YYYY-MM-DD';

Your document does not contain any element with class content-nav, thus the method .offset() returns undefined which indeed has no top property.

You can see for yourself in this fiddle

alert($('.content-nav').offset());

(you will see "undefined")

To avoid crashing the whole code, you can have such code instead:

var top = ($('.content-nav').offset() || { "top": NaN }).top;
if (isNaN(top)) {
    alert("something is wrong, no top");
} else {
    alert(top);
}

Updated fiddle.

OS X tends to prefix the system account names with "_"; you don't say what version of OS X you're using, but at least in 10.8 and 10.9 the _postgres user exists in a default install. Note that you won't be able to su to this account (except as root), since it doesn't have a password. sudo -u _postgres, on the other hand, should work fine.

"Resource temporarily unavailable" is the error message corresponding to EAGAIN, which means that the operation would have blocked but nonblocking operation was requested. For send(), that could be due to any of:

• explicitly marking the file descriptor as nonblocking with fcntl(); or
• passing the MSG_DONTWAIT flag to send(); or
• setting a send timeout with the SO_SNDTIMEO socket option.

Download version tar.gz for windows and just extract files to the folder by your needs. On the left pane, you can select which version of openjdk to download

JDK vs OpenJDK

curl -u username:password http://
curl -u username http://

From the documentation page:

-u, --user <user:password>

Specify the user name and password to use for server authentication. Overrides -n, --netrc and --netrc-optional.

If you simply specify the user name, curl will prompt for a password.

The user name and passwords are split up on the first colon, which makes it impossible to use a colon in the user name with this option. The password can, still.

When using Kerberos V5 with a Windows based server you should include the Windows domain name in the user name, in order for the server to succesfully obtain a Kerberos Ticket. If you don't then the initial authentication handshake may fail.

When using NTLM, the user name can be specified simply as the user name, without the domain, if there is a single domain and forest in your setup for example.

To specify the domain name use either Down-Level Logon Name or UPN (User Principal Name) formats. For example, EXAMPLE\user and [email protected] respectively.

If you use a Windows SSPI-enabled curl binary and perform Kerberos V5, Negotiate, NTLM or Digest authentication then you can tell curl to select the user name and password from your environment by specifying a single colon with this option: "-u :".

If this option is used several times, the last one will be used.

http://curl.haxx.se/docs/manpage.html#-u

Note that you do not need --basic flag as it is the default.

It also can be run by exporting the bash and sh of the gitbash C:\Program Files\git\bin\ in the Advance section of the environment variable of the Windows Server.

In Advance section in the path var kindly add the C:\Program Files\git\bin\ which will make the bash and the sh of the git-bash to be executable from the window cmd.

Then,

Run the shell file as

bash shellscript.sh or sh shellscript.sh

There seems to be some misunderstanding here about the Bash builtin true, and more specifically, about how Bash expands and interprets expressions inside brackets.

The code in miku's answer has absolutely nothing to do with the Bash builtin true, nor /bin/true, nor any other flavor of the true command. In this case, true is nothing more than a simple character string, and no call to the true command/builtin is ever made, neither by the variable assignment, nor by the evaluation of the conditional expression.

The following code is functionally identical to the code in the miku's answer:

the_world_is_flat=yeah
if [ "$the_world_is_flat" = yeah ]; then
    echo 'Be careful not to fall off!'
fi

The only difference here is that the four characters being compared are 'y', 'e', 'a', and 'h' instead of 't', 'r', 'u', and 'e'. That's it. There's no attempt made to call a command or builtin named yeah, nor is there (in miku's example) any sort of special handling going on when Bash parses the token true. It's just a string, and a completely arbitrary one at that.

Update (2014-02-19): After following the link in miku's answer, now I see where some of the confusion is coming from. Miku's answer uses single brackets, but the code snippet he links to does not use brackets. It's just:

the_world_is_flat=true
if $the_world_is_flat; then
  echo 'Be careful not to fall off!'
fi

Both code snippets will behave the same way, but the brackets completely change what's going on under the hood.

Here's what Bash is doing in each case:

No brackets:

1. Expand the variable $the_world_is_flat to the string "true".
2. Attempt to parse the string "true" as a command.
3. Find and run the true command (either a builtin or /bin/true, depending on the Bash version).
4. Compare the exit code of the true command (which is always 0) with 0. Recall that in most shells, an exit code of 0 indicates success and anything else indicates failure.
5. Since the exit code was 0 (success), execute the if statement's then clause

Brackets:

1. Expand the variable $the_world_is_flat to the string "true".
2. Parse the now-fully-expanded conditional expression, which is of the form string1 = string2. The = operator is bash's string comparison operator. So...
3. Do a string comparison on "true" and "true".
4. Yep, the two strings were the same, so the value of the conditional is true.
5. Execute the if statement's then clause.

The no-brackets code works, because the true command returns an exit code of 0, which indicates success. The bracketed code works, because the value of $the_world_is_flat is identical to the string literal true on the right side of the =.

Just to drive the point home, consider the following two snippets of code:

This code (if run with root privileges) will reboot your computer:

var=reboot
if $var; then
  echo 'Muahahaha! You are going down!'
fi

This code just prints "Nice try." The reboot command is not called.

var=reboot
if [ $var ]; then
  echo 'Nice try.'
fi

Update (2014-04-14) To answer the question in the comments regarding the difference between = and ==: AFAIK, there is no difference. The == operator is a Bash-specific synonym for =, and as far as I've seen, they work exactly the same in all contexts.

Note, however, that I'm specifically talking about the = and == string comparison operators used in either [ ] or [[ ]] tests. I'm not suggesting that = and == are interchangeable everywhere in bash.

For example, you obviously can't do variable assignment with ==, such as var=="foo" (well technically you can do this, but the value of var will be "=foo", because Bash isn't seeing an == operator here, it's seeing an = (assignment) operator, followed by the literal value ="foo", which just becomes "=foo").

Also, although = and == are interchangeable, you should keep in mind that how those tests work does depend on whether you're using it inside [ ] or [[ ]], and also on whether or not the operands are quoted. You can read more about that in Advanced Bash Scripting Guide: 7.3 Other Comparison Operators (scroll down to the discussion of = and ==).

Screen size in Android is grouped into categories ldpi, mdpi, hdpi, xhdpi, xxhdpi and xxxhdpi. Screen density is the amount of pixels within an area (like inch) of the screen. Generally it is measured in dots-per-inch (dpi).

PX(Pixels):

• our usual standard pixel which maps to the screen pixel. px is meant for absolute pixels. This is used if you want to give in terms of absolute pixels for width or height. Not recommended.

DP/DIP(Density pixels / Density independent pixels):

• dip == dp. In earlier Android versions dip was used and later changed to dp. This is alternative of px.

• Generally we never use px because it is absolute value. If you use px to set width or height, and if that application is being downloaded into different screen sized devices, then that view will not stretch as per the screen original size.

• dp is highly recommended to use in place of px. Use dp if you want to mention width and height to grow & shrink dynamically based on screen sizes.

• if we give dp/dip, android will automatically calculate the pixel size on the basis of 160 pixel sized screen.

SP(Scale independent pixels):

• scaled based on user’s font size preference. Fonts should use sp.

• when mentioning the font sizes to fit for various screen sizes, use sp. This is similar to dp.Use sp especially for font sizes to grow & shrink dynamically based on screen sizes

Android Documentation says:

when specifying dimensions, always use either dp or sp units. A dp is a density-independent pixel that corresponds to the physical size of a pixel at 160 dpi. An sp is the same base unit, but is scaled by the user's preferred text size (it’s a scale-independent pixel), so you should use this measurement unit when defining text size

A short solution:

use Dotenv;

with(new Dotenv(app()->environmentPath(), app()->environmentFile()))->overload();
with(new LoadConfiguration())->bootstrap(app());

In my case I needed to re-establish database connection after altering .env programmatically, but it didn't work , If you get into this trouble try this

app('db')->purge($connection->getName()); 

after reloading .env , that's because Laravel App could have accessed the default connection before and the \Illuminate\Database\DatabaseManager needs to re-read config parameters.

Any chance that you changed the name of your table view from "tableView" to "myTableView" at some point?

Use a DataTrigger:

<DataGrid ItemsSource="{Binding YourItemsSource}">
    <DataGrid.RowStyle>
        <Style TargetType="DataGridRow"> 
            <Style.Triggers>
                <DataTrigger Binding="{Binding State}" Value="State1">
                    <Setter Property="Background" Value="Red"></Setter>
                </DataTrigger>
                <DataTrigger Binding="{Binding State}" Value="State2">
                    <Setter Property="Background" Value="Green"></Setter>
                </DataTrigger>
            </Style.Triggers>
        </Style>
    </DataGrid.RowStyle>
</DataGrid>

For the record, none of the aforementioned Git Python libraries seem to contain a "git status" equivalent, which is really the only thing I would want since dealing with the rest of the git commands via subprocess is so easy.

The Oracle and OpenJDK JVMs are the same and have the same GC features (as of the latest versions 10+). Prior to Oracle managing the OpenJDK JVM there were concrete differences that made that old Openjdk JVM almost unusable in many environments. The JVMs are now the same.

The JDKs which include the JVM as part of the Kit, differ by licensing, release and maintenance schedule, and the software libraries included in the JDK. Crucial differences to me also mean things that would make code not run if not present. Not only licensing.

For people Googling and want more general rules about selecting with data-attributes:

$("[data-test]") will select any element that merely has the data attribute (no matter the value of the attribute). Including:

<div data-test=value>attributes with values</div>
<div data-test>attributes without values</div>

$('[data-test~="foo"]') will select any element where the data attribute contains foo but doesn't have to be exact, such as:

<div data-test="foo">Exact Matches</div>
<div data-test="this has the word foo">Where the Attribute merely contains "foo"</div>

$('[data-test="the_exact_value"]') will select any element where the data attribute exact value is the_exact_value, for example:

<div data-test="the_exact_value">Exact Matches</div>

but not

<div data-test="the_exact_value foo">This won't match</div>

As others point out, the user name is usually anonymous, and the password is usually your e-mail address, but this is not universally true, and has been found not to work for certain anonymous FTP sites. For example, at least some cPanel sites seem to deviate from the norm, and if given the traditional user name without domain, one of various errors may result:

If the server uses Pure-FTP as the FTP server:

421 Can't change directory to /var/ftp/ error message.

If the server uses ProFTP as the FTP server:

530 Login Authentication Failed error message.

When one of the aforementioned errors occurs when attempting anonymous access, try including a domain with the username. For example, where example.com is the domain used in your e-mail address:

User name: [email protected]

In the specific case of a cPanel site, the password value is unimportant, and may be left blank, but there is no harm in providing a "traditional" anonymous password formatted as an e-mail address.

For reference, this answer is based on content found on a documentation.cpanel.net Anonymous FTP page. At the time of this writing, it stated:

When users log in to FTP anonymously, they must format usernames as [email protected], where example.com represents the user's domain name. This requirement directs your server to the correct public_ftp directory.

Seen on the Udacity deep learning foundation course:

df = pd.read_csv('my.csv')
...
regr = LinearRegression()
regr.fit(df[['column x']], df[['column y']])

I also just found out how to do this with the Excel Name Manager (Formulas > Defined Names Section > Name Manager).

You can define a variable that doesn't have to "live" within a cell and then you can use it in formulas.

No. Private fields are not inherited... and that's why Protected was invented. It is by design. I guess this justified the existence of protected modifier.

Now coming to the contexts. What you mean by inherited -- if it is there in the object created from derived class? yes, it is.

If you mean can it be useful to derived class. Well, no.

Now, when you come to functional programming the private field of super class is not inherited in a meaningful way for the subclass. For the subclass, a private field of super class is same as a private field of any other class.

Functionally, it's not inherited. But ideally, it is.

OK, just looked into Java tutorial they quote this:

Private Members in a Superclass

A subclass does not inherit the private members of its parent class. However, if the superclass has public or protected methods for accessing its private fields, these can also be used by the subclass.

refer: http://download.oracle.com/javase/tutorial/java/IandI/subclasses.html

I agree, that the field is there. But, subclass does not get any privilege on that private field. To a subclass, the private field is same as any private field of any other class.

I believe it's purely matter of point-of-view. You may mould the argument either side. It's better justify both way.

you don't have to use regex. In your favourite language, split on spaces, go over the splitted words, check for cat and mat. eg in Python

>>> for line in open("file"):
...     g=0;f=0
...     s = line.split()
...     for item in s:
...         if item =="cat": f=1
...         if item =="mat": g=1
...     if (g,f)==(1,1): print "found: " ,line.rstrip()

found:  The cat slept on the mat in front of the fire.
found:  At 5:00 pm, I found the cat scratching the wool off the mat.

While I do love using CHECKSUM, I feel that a better way to go is using NEWID(), just because you don't have to go through a complicated math to generate simple numbers .

ROUND( 1000 *RAND(convert(varbinary, newid())), 0)

You can replace the 1000 with whichever number you want to set as the limit, and you can always use a plus sign to create a range, let's say you want a random number between 100 and 200, you can do something like :

100 + ROUND( 100 *RAND(convert(varbinary, newid())), 0)

Putting it together in your query :

UPDATE CattleProds 
SET SheepTherapy= ROUND( 1000 *RAND(convert(varbinary, newid())), 0)
WHERE SheepTherapy IS NULL
