You can add these single quotes with template literals:

var text = "http://example.com"_x000D_
var quoteText = `'${text}'`_x000D_
_x000D_
console.log(quoteText)

Docs are here. Browsers that support template literals listed here.

There's some duplicates that touch on this, and nobody really expounds on it. I'll borrow the accepted answer example to illustrate

http.open('POST', url, true);
http.send('lorem=ipsum&name=binny');

I oversimplified this (I use http.onload(function() {}) instead of that answer's older methodology) for the sake of illustration. If you use this as-is, you'll find your server is probably interpreting the POST body as a string and not actual key=value parameters (i.e. PHP won't show any $_POST variables). You must pass the form header in to get that, and do that before http.send()

http.setRequestHeader('Content-type', 'application/x-www-form-urlencoded');

If you're using JSON and not URL-encoded data, pass application/json instead

Make sure that you also have configured properly an emulated device. Android Studio may come with one that shows up in the list of emulated devices but that is not set to work with the SDK version you are using.

Try creating a new emulated device in the AVD Manager (Tools->Android>AVD Manager) and selecting that as the target.

The provided answers do not work in Firefox (Quantum). The event listener needs to be changed from mousewheel to wheel:

$(':input[type=number]').on('wheel',function(e){ $(this).blur(); });

This code works on Firefox Quantum and Chrome.

Just use this for the closing tag:

  @:</tr>

And leave your if/else as is.

Seems like the if statement doesn't wanna' work.

It works fine. You're working in 2 language-spaces here, it seems only proper not to split open/close sandwiches over the border.

Alternatively, you could create a temporary symbolic link to your file:

ln -s /data/to/zip/data.txt data.txt
zip /dir/to/file/newZip !$
rm !$

This works also for a directory.

For my Azpen A727, the Windows driver installed correctly, so only step 3 of Mohammad's answer was necessary.

While JS is probably the way to go, it could be done with HTML and CSS only.

Here you have a fake radio button which is really a label for a real hidden radio button. By doing that, you get exactly the effect you need.

<style>
   #uncheck>input { display: none }
   input:checked + label { display: none }
   input:not(:checked) + label + label{ display: none } 
</style>

<div id='uncheck'>
  <input type="radio" name='food' id="box1" /> 
  Pizza 
    <label for='box1'>&#9678;</label> 
    <label for='box0'>&#9673;</label>
  <input type="radio" name='food' id="box2" /> 
  Ice cream 
    <label for='box2'>&#9678;</label> 
    <label for='box0'>&#9673;</label>
  <input type="radio" name='food' id="box0" checked />
</div>

See it here: https://jsfiddle.net/tn70yxL8/2/

Now, that assumes you need non-selectable labels.

If you were willing to include the labels, you can technically avoid repeating the "uncheck" label by changing its text in CSS, see here: https://jsfiddle.net/7tdb6quy/2/

Let's get one thing out of the way first. The explanation that yield from g is equivalent to for v in g: yield v does not even begin to do justice to what yield from is all about. Because, let's face it, if all yield from does is expand the for loop, then it does not warrant adding yield from to the language and preclude a whole bunch of new features from being implemented in Python 2.x.

What yield from does is it establishes a transparent bidirectional connection between the caller and the sub-generator:

• The connection is "transparent" in the sense that it will propagate everything correctly too, not just the elements being generated (e.g. exceptions are propagated).

• The connection is "bidirectional" in the sense that data can be both sent from and to a generator.

(If we were talking about TCP, yield from g might mean "now temporarily disconnect my client's socket and reconnect it to this other server socket".)

BTW, if you are not sure what sending data to a generator even means, you need to drop everything and read about coroutines first—they're very useful (contrast them with subroutines), but unfortunately lesser-known in Python. Dave Beazley's Curious Course on Coroutines is an excellent start. Read slides 24-33 for a quick primer.

Reading data from a generator using yield from

def reader():
    """A generator that fakes a read from a file, socket, etc."""
    for i in range(4):
        yield '<< %s' % i

def reader_wrapper(g):
    # Manually iterate over data produced by reader
    for v in g:
        yield v

wrap = reader_wrapper(reader())
for i in wrap:
    print(i)

# Result
<< 0
<< 1
<< 2
<< 3

Instead of manually iterating over reader(), we can just yield from it.

def reader_wrapper(g):
    yield from g

That works, and we eliminated one line of code. And probably the intent is a little bit clearer (or not). But nothing life changing.

Sending data to a generator (coroutine) using yield from - Part 1

Now let's do something more interesting. Let's create a coroutine called writer that accepts data sent to it and writes to a socket, fd, etc.

def writer():
    """A coroutine that writes data *sent* to it to fd, socket, etc."""
    while True:
        w = (yield)
        print('>> ', w)

Now the question is, how should the wrapper function handle sending data to the writer, so that any data that is sent to the wrapper is transparently sent to the writer()?

def writer_wrapper(coro):
    # TBD
    pass

w = writer()
wrap = writer_wrapper(w)
wrap.send(None)  # "prime" the coroutine
for i in range(4):
    wrap.send(i)

# Expected result
>>  0
>>  1
>>  2
>>  3

The wrapper needs to accept the data that is sent to it (obviously) and should also handle the StopIteration when the for loop is exhausted. Evidently just doing for x in coro: yield x won't do. Here is a version that works.

def writer_wrapper(coro):
    coro.send(None)  # prime the coro
    while True:
        try:
            x = (yield)  # Capture the value that's sent
            coro.send(x)  # and pass it to the writer
        except StopIteration:
            pass

Or, we could do this.

def writer_wrapper(coro):
    yield from coro

That saves 6 lines of code, make it much much more readable and it just works. Magic!

Sending data to a generator yield from - Part 2 - Exception handling

Let's make it more complicated. What if our writer needs to handle exceptions? Let's say the writer handles a SpamException and it prints *** if it encounters one.

class SpamException(Exception):
    pass

def writer():
    while True:
        try:
            w = (yield)
        except SpamException:
            print('***')
        else:
            print('>> ', w)

What if we don't change writer_wrapper? Does it work? Let's try

# writer_wrapper same as above

w = writer()
wrap = writer_wrapper(w)
wrap.send(None)  # "prime" the coroutine
for i in [0, 1, 2, 'spam', 4]:
    if i == 'spam':
        wrap.throw(SpamException)
    else:
        wrap.send(i)

# Expected Result
>>  0
>>  1
>>  2
***
>>  4

# Actual Result
>>  0
>>  1
>>  2
Traceback (most recent call last):
  ... redacted ...
  File ... in writer_wrapper
    x = (yield)
__main__.SpamException

Um, it's not working because x = (yield) just raises the exception and everything comes to a crashing halt. Let's make it work, but manually handling exceptions and sending them or throwing them into the sub-generator (writer)

def writer_wrapper(coro):
    """Works. Manually catches exceptions and throws them"""
    coro.send(None)  # prime the coro
    while True:
        try:
            try:
                x = (yield)
            except Exception as e:   # This catches the SpamException
                coro.throw(e)
            else:
                coro.send(x)
        except StopIteration:
            pass

This works.

# Result
>>  0
>>  1
>>  2
***
>>  4

But so does this!

def writer_wrapper(coro):
    yield from coro

The yield from transparently handles sending the values or throwing values into the sub-generator.

This still does not cover all the corner cases though. What happens if the outer generator is closed? What about the case when the sub-generator returns a value (yes, in Python 3.3+, generators can return values), how should the return value be propagated? That yield from transparently handles all the corner cases is really impressive. yield from just magically works and handles all those cases.

I personally feel yield from is a poor keyword choice because it does not make the two-way nature apparent. There were other keywords proposed (like delegate but were rejected because adding a new keyword to the language is much more difficult than combining existing ones.

In summary, it's best to think of yield from as a transparent two way channel between the caller and the sub-generator.

In such a small cases where difference is less than 0 milliseconds you can get difference in nano seconds as well.

Those blank lines between your ?> and <?php tags are being sent to the client.

When the first one of those is sent, it causes your headers to be sent first.

Once that happens, you can't modify the headers any more.

Remove those unnecessary tags, have it all in one big <?php block.

Well the above answers have give a good explanations to half of the question. For the other half.

Why don't just hide the scroll bar itself. This way it will look more appealing as most of the people ( including me ) hate the scroll bar. You can use this code

::-webkit-scrollbar {
    width: 0px;  /* Remove scrollbar space */
    background: transparent;  /* Optional: just make scrollbar invisible */
}

This piece of CSS worked for me:

input:focus::-webkit-input-placeholder {
        color:transparent;

}

Yes. 'Z' stands for Zulu time, which is also GMT and UTC.

From http://en.wikipedia.org/wiki/Coordinated_Universal_Time:

The UTC time zone is sometimes denoted by the letter Z—a reference to the equivalent nautical time zone (GMT), which has been denoted by a Z since about 1950. The letter also refers to the "zone description" of zero hours, which has been used since 1920 (see time zone history). Since the NATO phonetic alphabet and amateur radio word for Z is "Zulu", UTC is sometimes known as Zulu time.

Technically, because the definition of nautical time zones is based on longitudinal position, the Z time is not exactly identical to the actual GMT time 'zone'. However, since it is primarily used as a reference time, it doesn't matter what area of Earth it applies to as long as everyone uses the same reference.

From wikipedia again, http://en.wikipedia.org/wiki/Nautical_time:

Around 1950, a letter suffix was added to the zone description, assigning Z to the zero zone, and A–M (except J) to the east and N–Y to the west (J may be assigned to local time in non-nautical applications; zones M and Y have the same clock time but differ by 24 hours: a full day). These were to be vocalized using a phonetic alphabet which pronounces the letter Z as Zulu, leading sometimes to the use of the term "Zulu Time". The Greenwich time zone runs from 7.5°W to 7.5°E longitude, while zone A runs from 7.5°E to 22.5°E longitude, etc.

I was struggling to get this to work for a while. Once you change the extension to .pyw, make sure that you open properties of the file and direct the "open with" path to pythonw.exe.

Sorry for only commenting in the first place, but i'm posting almost every day a similar comment since many people think that it would be smart to encapsulate ADO.NET functionality into a DB-Class(me too 10 years ago). Mostly they decide to use static/shared objects since it seems to be faster than to create a new object for any action.

That is neither a good idea in terms of peformance nor in terms of fail-safety.

Don't poach on the Connection-Pool's territory

There's a good reason why ADO.NET internally manages the underlying Connections to the DBMS in the ADO-NET Connection-Pool:

In practice, most applications use only one or a few different configurations for connections. This means that during application execution, many identical connections will be repeatedly opened and closed. To minimize the cost of opening connections, ADO.NET uses an optimization technique called connection pooling.

Connection pooling reduces the number of times that new connections must be opened. The pooler maintains ownership of the physical connection. It manages connections by keeping alive a set of active connections for each given connection configuration. Whenever a user calls Open on a connection, the pooler looks for an available connection in the pool. If a pooled connection is available, it returns it to the caller instead of opening a new connection. When the application calls Close on the connection, the pooler returns it to the pooled set of active connections instead of closing it. Once the connection is returned to the pool, it is ready to be reused on the next Open call.

So obviously there's no reason to avoid creating,opening or closing connections since actually they aren't created,opened and closed at all. This is "only" a flag for the connection pool to know when a connection can be reused or not. But it's a very important flag, because if a connection is "in use"(the connection pool assumes), a new physical connection must be openend to the DBMS what is very expensive.

So you're gaining no performance improvement but the opposite. If the maximum pool size specified (100 is the default) is reached, you would even get exceptions(too many open connections ...). So this will not only impact the performance tremendously but also be a source for nasty errors and (without using Transactions) a data-dumping-area.

If you're even using static connections you're creating a lock for every thread trying to access this object. ASP.NET is a multithreading environment by nature. So theres a great chance for these locks which causes performance issues at best. Actually sooner or later you'll get many different exceptions(like your ExecuteReader requires an open and available Connection).

Conclusion:

• Don't reuse connections or any ADO.NET objects at all.
• Don't make them static/shared(in VB.NET)
• Always create, open(in case of Connections), use, close and dispose them where you need them(f.e. in a method)
• use the using-statement to dispose and close(in case of Connections) implicitely

That's true not only for Connections(although most noticable). Every object implementing IDisposable should be disposed(simplest by using-statement), all the more in the System.Data.SqlClient namespace.

All the above speaks against a custom DB-Class which encapsulates and reuse all objects. That's the reason why i commented to trash it. That's only a problem source.

Edit: Here's a possible implementation of your retrievePromotion-method:

public Promotion retrievePromotion(int promotionID)
{
    Promotion promo = null;
    var connectionString = System.Configuration.ConfigurationManager.ConnectionStrings["MainConnStr"].ConnectionString;
    using (SqlConnection connection = new SqlConnection(connectionString))
    {
        var queryString = "SELECT PromotionID, PromotionTitle, PromotionURL FROM Promotion WHERE PromotionID=@PromotionID";
        using (var da = new SqlDataAdapter(queryString, connection))
        {
            // you could also use a SqlDataReader instead
            // note that a DataTable does not need to be disposed since it does not implement IDisposable
            var tblPromotion = new DataTable();
            // avoid SQL-Injection
            da.SelectCommand.Parameters.Add("@PromotionID", SqlDbType.Int);
            da.SelectCommand.Parameters["@PromotionID"].Value = promotionID;
            try
            {
                connection.Open(); // not necessarily needed in this case because DataAdapter.Fill does it otherwise 
                da.Fill(tblPromotion);
                if (tblPromotion.Rows.Count != 0)
                {
                    var promoRow = tblPromotion.Rows[0];
                    promo = new Promotion()
                    {
                        promotionID    = promotionID,
                        promotionTitle = promoRow.Field<String>("PromotionTitle"),
                        promotionUrl   = promoRow.Field<String>("PromotionURL")
                    };
                }
            }
            catch (Exception ex)
            {
                // log this exception or throw it up the StackTrace
                // we do not need a finally-block to close the connection since it will be closed implicitely in an using-statement
                throw;
            }
        }
    }
    return promo;
}

string = string.replace(/[\W_]/g, "_");

I created my own little lazy Math-Object for degree (MathD), hope it helps:

//helper
/**
 * converts degree to radians
 * @param degree
 * @returns {number}
 */
var toRadians = function (degree) {
    return degree * (Math.PI / 180);
};

/**
 * Converts radian to degree
 * @param radians
 * @returns {number}
 */
var toDegree = function (radians) {
    return radians * (180 / Math.PI);
}

/**
 * Rounds a number mathematical correct to the number of decimals
 * @param number
 * @param decimals (optional, default: 5)
 * @returns {number}
 */
var roundNumber = function(number, decimals) {
    decimals = decimals || 5;
    return Math.round(number * Math.pow(10, decimals)) / Math.pow(10, decimals);
}
//the object
var MathD = {
    sin: function(number){
        return roundNumber(Math.sin(toRadians(number)));
    },
    cos: function(number){
        return roundNumber(Math.cos(toRadians(number)));
    },
    tan: function(number){
        return roundNumber(Math.tan(toRadians(number)));
    },
    asin: function(number){
        return roundNumber(toDegree(Math.asin(number)));
    },
    acos: function(number){
       return roundNumber(toDegree(Math.acos(number)));
   },
   atan: function(number){
       return roundNumber(toDegree(Math.atan(number)));
   }
};

(for fellow googlers)

If you are building a serious pipeline with the Build Flow Plugin, you can pass parameters between jobs with the DSL like this :

Supposing an available string parameter "CVS_TAG", in order to pass it to other jobs :

build("pipeline_begin", CVS_TAG: params['CVS_TAG'])
parallel (
   // will be scheduled in parallel.
   { build("pipeline_static_analysis", CVS_TAG: params['CVS_TAG']) },
   { build("pipeline_nonreg", CVS_TAG: params['CVS_TAG']) }
)
// will be triggered after previous jobs complete
build("pipeline_end", CVS_TAG: params['CVS_TAG'])

Hint for displaying available variables / params :

// output values
out.println '------------------------------------'
out.println 'Triggered Parameters Map:'
out.println params
out.println '------------------------------------'
out.println 'Build Object Properties:'
build.properties.each { out.println "$it.key -> $it.value" }
out.println '------------------------------------'

Maybe the most intuitive solution is probably to use the stringr function str_remove which is even easier than str_replace as it has only 1 argument instead of 2.

The only tricky part in your example is that you want to keep the underscore but its possible: You must match the regular expression until it finds the specified string pattern (?=pattern).

See example:

strings = c("TGAS_1121", "MGAS_1432", "ATGAS_1121")
strings %>% stringr::str_remove(".+?(?=_)")

[1] "_1121" "_1432" "_1121"

I used this format - but...I found I had to run it three or more times to get it to actually change every instance which I found extremely strange. Running it once would change some in each file but not all. Running exactly the same string two-four times would catch all instances.

find . -type f -name '*.txt' -exec sed -i '' s/thistext/newtext/ {} +

This issue can also happen due to the following

1.In the Web.Config

<system.webServer>
     <modules runAllManagedModulesForAllRequests="true" /> 
<system.webServer>

2.Make sure the following are available in the bin folder on the server where the Web API is deployed

• System.Net.Http

• System.Net.Http.Formatting

• System.Web.Http.WebHost

• System.Web.Http

These assemblies won't be copied in the bin folder by default if the publish is through Visual Studio because the Web API packages are installed through Nuget in the development machine. Still if you want to achieve these files to be available as part of Visual Studio publish then you need to set CopyLocal to True for these Assemblies

Honestly even if MongoDB is slower, MongoDB definitely makes me and you code faster.... no need to worry about silly table columns, row or entity migrations...

With MongoDB, you just instantiate a class and save!

this helper method get fragment from top of stack:

public Fragment getTopFragment() {
    if (getSupportFragmentManager().getBackStackEntryCount() == 0) {
        return null;
    }
    String fragmentTag = getSupportFragmentManager().getBackStackEntryAt(getSupportFragmentManager().getBackStackEntryCount() - 1).getName();
    return getSupportFragmentManager().findFragmentByTag(fragmentTag);
}

Not sure if this is correct in any sense but this seems to work for me.

It's quite handy for "quick" tests... Try to avoid global vars tho, because every says so... ;- )

I spent ages going through all the answers on this page but found the one that worked for me in the comments of the OP question by s-walsh

The answer is to use pip3:

$ pip3 install <name-of-install>

When you decide between fixed width and fluid width you need to think in terms of your ENTIRE page. Generally, you want to pick one or the other, but not both. The examples you listed in your question are, in-fact, in the same fixed-width page. In other words, the Scaffolding page is using a fixed-width layout. The fixed grid and fluid grid on the Scaffolding page are not meant to be examples, but rather the documentation for implementing fixed and fluid width layouts.

The proper fixed width example is here. The proper fluid width example is here.

When observing the fixed width example, you should not see the content changing sizes when your browser is greater than 960px wide. This is the maximum (fixed) width of the page. Media queries in a fixed-width design will designate the minimum widths for particular styles. You will see this in action when you shrink your browser window and see the layout snap to a different size.

Conversely, the fluid-width layout will always stretch to fit your browser window, no matter how wide it gets. The media queries indicate when the styles change, but the width of containers are always a percentage of your browser window (rather than a fixed number of pixels).

The 'responsive' media queries are all ready to go. You just need to decide if you want to use a fixed width or fluid width layout for your page.

Previously, in bootstrap 2, you had to use row-fluid inside a fluid container and row inside a fixed container. With the introduction of bootstrap 3, row-fluid was removed, do no longer use it.

EDIT: As per the comments, some jsFiddles for:

• fluid non-responsive layout,
• fluid responsive layout,
• fixed non-responsive layout,
• fixed responsive layout.

These fiddles are completely Bootstrap-free, based on pure CSS media queries, which makes them a good starting point, for anyone willing to craft similar solution without using Twitter Bootstrap.

you can check this code . i hope you will easily understand.

I got similar error msgs. I run svn clean-up, and then tried "get clock" for a few times. Then this error was gone.

Try to put all your <script ...></script> tags before the </body> tag. Perhaps the js is trying to access an object of the DOM before it's built up.

This phrase is almost certainly an analogy with a phase in house construction — "stubbing out" plumbing. During construction, while the walls are still open, the rough plumbing is put in. This is necessary for the construction to continue. Then, when everything around it is ready enough, one comes back and adds faucets and toilets and the actual end-product stuff. (See for example How to Install a Plumbing Stub-Out.)

When you "stub out" a function in programming, you build enough of it to work around (for testing or for writing other code). Then, you come back later and replace it with the full implementation.

for 1D and 2D arrays you can use np.savetxt to print using a specific format string:

>>> import sys
>>> x = numpy.arange(20).reshape((4,5))
>>> numpy.savetxt(sys.stdout, x, '%5.2f')
 0.00  1.00  2.00  3.00  4.00
 5.00  6.00  7.00  8.00  9.00
10.00 11.00 12.00 13.00 14.00
15.00 16.00 17.00 18.00 19.00

Your options with numpy.set_printoptions or numpy.array2string in v1.3 are pretty clunky and limited (for example no way to suppress scientific notation for large numbers). It looks like this will change with future versions, with numpy.set_printoptions(formatter=..) and numpy.array2string(style=..).

The issue, I believe, is that the Json action result is intended to take an object (your model) and create an HTTP response with content as the JSON-formatted data from your model object.

What you are passing to the controller's Json method, though, is a JSON-formatted string object, so it is "serializing" the string object to JSON, which is why the content of the HTTP response is surrounded by double-quotes (I'm assuming that is the problem).

I think you can look into using the Content action result as an alternative to the Json action result, since you essentially already have the raw content for the HTTP response available.

return this.Content(returntext, "application/json");
// not sure off-hand if you should also specify "charset=utf-8" here, 
//  or if that is done automatically

Another alternative would be to deserialize the JSON result from the service into an object and then pass that object to the controller's Json method, but the disadvantage there is that you would be de-serializing and then re-serializing the data, which may be unnecessary for your purposes.

You can do it in a less than a minute with Google Drive (and free, no hassles)

• Bulk Upload all your images on imgur.com

• Copy the Links of all the images together, appended with .jpg. Only imgur lets you do copy all the image links together, do that using the image tab top right.

• Use http://TextMechanic.co to prepend and append each line with this: Prefix : =image(" AND Suffix : ", 1)

So that it looks like this =image("URL", 1)

• Copy All

• Paste it in Google Spreadsheet

• Voila!

The easiest way to match both

^\([0-9]{3}\)[0-9]{3}-[0-9]{4}$

and

^[0-9]{3}-[0-9]{3}-[0-9]{4}$

is to use alternation ((...|...)): specify them as two mostly-separate options:

^(\([0-9]{3}\)|[0-9]{3}-)[0-9]{3}-[0-9]{4}$

By the way, when Americans put the area code in parentheses, we actually put a space after that; for example, I'd write (123) 123-1234, not (123)123-1234. So you might want to write:

^(\([0-9]{3}\) |[0-9]{3}-)[0-9]{3}-[0-9]{4}$

(Though it's probably best to explicitly demonstrate the format that you expect phone numbers to be in.)

just another way to do it.

Label lbl = new Label();
new ToolTip().SetToolTip(lbl, "tooltip text here");

var test = parseInt($("#testid").val());

I had the same issue, and I couldn't comment on @Sven Marnach answer (not enough rep, gosh I remember when Stackoverflow first started...) anyway.

Adding a list of random numbers to a 10 X 10 matrix.

myNpArray = np.zeros([1, 10])
for x in range(1,11,1):
    randomList = [list(np.random.randint(99, size=10))]
    myNpArray = np.vstack((myNpArray, randomList))
myNpArray = myNpArray[1:]

Using np.zeros() an array is created with 1 x 10 zeros.

array([[0., 0., 0., 0., 0., 0., 0., 0., 0., 0.]])

Then a list of 10 random numbers is created using np.random and assigned to randomList. The loop stacks it 10 high. We just have to remember to remove the first empty entry.

myNpArray

array([[31., 10., 19., 78., 95., 58.,  3., 47., 30., 56.],
       [51., 97.,  5., 80., 28., 76., 92., 50., 22., 93.],
       [64., 79.,  7., 12., 68., 13., 59., 96., 32., 34.],
       [44., 22., 46., 56., 73., 42., 62.,  4., 62., 83.],
       [91., 28., 54., 69., 60., 95.,  5., 13., 60., 88.],
       [71., 90., 76., 53., 13., 53., 31.,  3., 96., 57.],
       [33., 87., 81.,  7., 53., 46.,  5.,  8., 20., 71.],
       [46., 71., 14., 66., 68., 65., 68., 32.,  9., 30.],
       [ 1., 35., 96., 92., 72., 52., 88., 86., 94., 88.],
       [13., 36., 43., 45., 90., 17., 38.,  1., 41., 33.]])

So in a function:

def array_matrix(random_range, array_size):
    myNpArray = np.zeros([1, array_size])
    for x in range(1, array_size + 1, 1):
        randomList = [list(np.random.randint(random_range, size=array_size))]
        myNpArray = np.vstack((myNpArray, randomList))
    return myNpArray[1:]

a 7 x 7 array using random numbers 0 - 1000

array_matrix(1000, 7)

array([[621., 377., 931., 180., 964., 885., 723.],
       [298., 382., 148., 952., 430., 333., 956.],
       [398., 596., 732., 422., 656., 348., 470.],
       [735., 251., 314., 182., 966., 261., 523.],
       [373., 616., 389.,  90., 884., 957., 826.],
       [587., 963.,  66., 154., 111., 529., 945.],
       [950., 413., 539., 860., 634., 195., 915.]])

The best solution is: from positive to negative or from negative to positive

For negative:

SELECT ABS(a) * -1 AS AbsoluteA, ABS(b) * -1 AS AbsoluteB
FROM YourTable

For positive:

SELECT ABS(a) AS AbsoluteA, ABS(b)  AS AbsoluteB
FROM YourTable

A pure RESTful API should use the underlying protocol standard features:

1. For HTTP, the RESTful API should comply with existing HTTP standard headers. Adding a new HTTP header violates the REST principles. Do not re-invent the wheel, use all the standard features in HTTP/1.1 standards - including status response codes, headers, and so on. RESTFul web services should leverage and rely upon the HTTP standards.

2. RESTful services MUST be STATELESS. Any tricks, such as token based authentication that attempts to remember the state of previous REST requests on the server violates the REST principles. Again, this is a MUST; that is, if you web server saves any request/response context related information on the server in attempt to establish any sort of session on the server, then your web service is NOT Stateless. And if it is NOT stateless it is NOT RESTFul.

Bottom-line: For authentication/authorization purposes you should use HTTP standard authorization header. That is, you should add the HTTP authorization / authentication header in each subsequent request that needs to be authenticated. The REST API should follow the HTTP Authentication Scheme standards.The specifics of how this header should be formatted are defined in the RFC 2616 HTTP 1.1 standards – section 14.8 Authorization of RFC 2616, and in the RFC 2617 HTTP Authentication: Basic and Digest Access Authentication.

I have developed a RESTful service for the Cisco Prime Performance Manager application. Search Google for the REST API document that I wrote for that application for more details about RESTFul API compliance here. In that implementation, I have chosen to use HTTP "Basic" Authorization scheme. - check out version 1.5 or above of that REST API document, and search for authorization in the document.

Try using double quotes and keeping the L in location lowercase...

header("location: http://linkhere.com/HERE_I_WANT_THE_VARIABLE");

or for example

header("location: http://linkhere.com/$variable");

No need to concatenate here to insert variables.

You don't "remove the character 'u' from a list", you encode Unicode strings. In fact the strings you have are perfectly fine for most uses; you will just need to encode them appropriately before outputting them.

The Internationalization API supports getting the user timezone, and is supported in all current browsers.

console.log(Intl.DateTimeFormat().resolvedOptions().timeZone)

Keep in mind that on some older browser versions that support the Internationalization API, the timeZone property is set to undefined rather than the user’s timezone string. As best as I can tell, at the time of writing (July 2017) all current browsers except for IE11 will return the user timezone as a string.

I am assuming (please correct me if I am wrong) that you want to re-display the edit page if the edit fails and to do this you are using a redirect.

You may have more luck by just returning the view again rather than trying to redirect the user, this way you will be able to use the ModelState to output any errors too.

Edit:

Updated based on feedback. You can place the previous URL in the viewModel, add it to a hidden field then use it again in the action that saves the edits.

For instance:

public ActionResult Index()
{
    return View();
}

[HttpGet] // This isn't required
public ActionResult Edit(int id)
{
   // load object and return in view
   ViewModel viewModel = Load(id);

   // get the previous url and store it with view model
   viewModel.PreviousUrl = System.Web.HttpContext.Current.Request.UrlReferrer;

   return View(viewModel);
}

[HttpPost]
public ActionResult Edit(ViewModel viewModel)
{
   // Attempt to save the posted object if it works, return index if not return the Edit view again

   bool success = Save(viewModel);
   if (success)
   {
       return Redirect(viewModel.PreviousUrl);
   }
   else
   {
      ModelState.AddModelError("There was an error");
      return View(viewModel);
   }
}

The BeginForm method for your view doesn't need to use this return URL either, you should be able to get away with:

@model ViewModel

@using (Html.BeginForm())
{
    ...
    <input type="hidden" name="PreviousUrl" value="@Model.PreviousUrl" />
}

Going back to your form action posting to an incorrect URL, this is because you are passing a URL as the 'id' parameter, so the routing automatically formats your URL with the return path.

This won't work because your form will be posting to an controller action that won't know how to save the edits. You need to post to your save action first, then handle the redirect within it.

Another way, which is a little bit easier for me is to use named pipes. Named pipes provided a way to synchronize and sending messages between different processes.

A.bash:

#!/bin/bash
msg="The Message"
echo $msg > A.pipe

B.bash:

#!/bin/bash
msg=`cat ./A.pipe`
echo "message from A : $msg"

Usage:

$ mkfifo A.pipe #You have to create it once
$ ./A.bash & ./B.bash # you have to run your scripts at the same time

B.bash will wait for message and as soon as A.bash sends the message, B.bash will continue its work.

It's not related to Ken's case directly, but such an error also can occur if you copied .h file and forgot to change #ifndef directive. In this case compiler will just skip definition of the class thinking that it's a duplication.

if (document.addEventListener) {
    document.addEventListener("click", attachEvent, false);
}
else {
    document.attachEvent("onclick", attachEvent);
}
function attachEvent(ev) {
    var target = ev.target || ev.srcElement;
    // custom code
}

myBook.Saved = true;
myBook.SaveCopyAs(xlsFileName);
myBook.Close(null, null, null);
myExcel.Workbooks.Close();
myExcel.Quit();

In my case the error was because one container created files in a folder that were mounted on the host file-system with docker-compose.

I just had to do remove the files created by the container on the host system and I was able to launch my project again.

sudo rm -Rf foldername

(I had to use sudo because the files were owned by the root user)

Docker version: 18.03.1

    .Visible = False
    .Width = TextBox1.Width + 4

You should not pass the call function hi() to the loop() function, This will give the result.

def hi():     
  print('hi')

def loop(f, n):         #f repeats n times
  if n<=0:
    return
  else:
    f()             
    loop(f, n-1)    

loop(hi, 5)            # Do not use hi() function inside loop() function

This is explained in the node eventEmitter documentation

What version of Node is this? What other code do you have? That isn't normal behavior.

In short, its: process.setMaxListeners(0);

Also see: node.js - request - How to “emitter.setMaxListeners()”?

Posting data is a matter of sending a query string (just like the way you would send it with an URL after the ?) as the request body.

This requires Content-Type and Content-Length headers, so the receiving server knows how to interpret the incoming data. ^(*)

var querystring = require('querystring');
var http = require('http');

var data = querystring.stringify({
      username: yourUsernameValue,
      password: yourPasswordValue
    });

var options = {
    host: 'my.url',
    port: 80,
    path: '/login',
    method: 'POST',
    headers: {
        'Content-Type': 'application/x-www-form-urlencoded',
        'Content-Length': Buffer.byteLength(data)
    }
};

var req = http.request(options, function(res) {
    res.setEncoding('utf8');
    res.on('data', function (chunk) {
        console.log("body: " + chunk);
    });
});

req.write(data);
req.end();

^(*) Sending data requires the Content-Type header to be set correctly, i.e. application/x-www-form-urlencoded for the traditional format that a standard HTML form would use.

It's easy to send JSON (application/json) in exactly the same manner; just JSON.stringify() the data beforehand.

URL-encoded data supports one level of structure (i.e. key and value). JSON is useful when it comes to exchanging data that has a nested structure.

The bottom line is: The server must be able to interpret the content type in question. It could be text/plain or anything else; there is no need to convert data if the receiving server understands it as it is.

Add a charset parameter (e.g. application/json; charset=Windows-1252) if your data is in an unusual character set, i.e. not UTF-8. This can be necessary if you read it from a file, for example.

The accepted answer throws a ProtocolException at:

OutputStream os = conn.getOutputStream();

because it does not enable the output for the URLConnection object. The solution should include this:

conn.setDoOutput(true);

to make it work.

Furthermore, if in the same Jenkins project we need to checkout several private GitHub repositories into several separate dirs under a project root. How can we do it please?

The Jenkin's Multiple SCMs Plugin has solved the several repositories problem for me very nicely. I have just got working a project build that checks out four different git repos under a common folder. (I'm a bit reluctant to use git super-projects as suggested previously by Lukasz Rzanek, as git is complex enough without submodules.)

Somewhere else in your code you have something that looks like this:

round = 42

Then when you write

round((a/b)*0.9*c)

that is interpreted as meaning a function call on the object bound to round, which is an int. And that fails.

The problem is whatever code binds an int to the name round. Find that and remove it.

https://docs.microsoft.com/en-us/sql/t-sql/statements/set-ansi-nulls-transact-sql

When SET ANSI_NULLS is ON, a SELECT statement that uses WHERE column_name = NULL returns zero rows even if there are null values in column_name. A SELECT statement that uses WHERE column_name <> NULL returns zero rows even if there are nonnull values in column_name.

For e.g

DECLARE @TempVariable VARCHAR(10)
SET @TempVariable = NULL

SET ANSI_NULLS ON
SELECT 'NO ROWS IF SET ANSI_NULLS ON' where    @TempVariable = NULL
-- IF ANSI_NULLS ON , RETURNS ZERO ROWS


SET ANSI_NULLS OFF
SELECT 'THERE WILL BE A ROW IF ANSI_NULLS OFF' where    @TempVariable =NULL
-- IF ANSI_NULLS OFF , THERE WILL BE ROW !

Here are the COMPLETE STEPS for remote access of MySQL (deployed on Amazon EC2):-

1. Add MySQL to inbound rules.

Go to security group of your ec2 instance -> edit inbound rules -> add new rule -> choose MySQL/Aurora and source to Anywhere.

2. Add bind-address = 0.0.0.0 to my.cnf

In instance console:

sudo vi /etc/mysql/my.cnf

this will open vi editor.
in my.cnf file, after [mysqld] add new line and write this:

bind-address = 0.0.0.0

Save file by entering :wq(enter)

now restart MySQL:

sudo /etc/init.d/mysqld restart

3. Create a remote user and grant privileges.

login to MySQL:

mysql -u root -p mysql (enter password after this)

Now write following commands:

CREATE USER 'jerry'@'localhost' IDENTIFIED BY 'jerrypassword';

CREATE USER 'jerry'@'%' IDENTIFIED BY 'jerrypassword';

GRANT ALL PRIVILEGES ON *.* to jerry@localhost IDENTIFIED BY 'jerrypassword' WITH GRANT OPTION;

GRANT ALL PRIVILEGES ON *.* to jerry@'%' IDENTIFIED BY 'jerrypassword' WITH GRANT OPTION;

FLUSH PRIVILEGES;

EXIT;

After this, MySQL dB can be remotely accessed by entering public dns/ip of your instance as MySQL Host Address, username as jerry and password as jerrypassword. (Port is set to default at 3306)

I got this error and fixed by appending the directory path in the loop. script not in the same directory as the files. dr1 ="~/test" directory variable

 fileop=open(dr1+"/"+fil,"r")

I solved the same problem, but I had to write more code. I created a server.js file, that uses express to register routes. It exposes a function,register , that can be used by other modules to register their own routes. It also exposes a function, startServer , to start listening to a port

server.js

const express = require('express');
const app = express();

const register = (path,method,callback) => methodCalled(path, method, callback)

const methodCalled = (path, method, cb) => {
  switch (method) {
    case 'get':
      app.get(path, (req, res) => cb(req, res))
      break;
    ...
    ...  
    default:
      console.log("there has been an error");
  }
}

const startServer = (port) => app.listen(port, () => {console.log(`successfully started at ${port}`)})

module.exports = {
  register,
  startServer
}

In another module, use this file to create a route.

help.js

const app = require('../server');

const registerHelp = () => {
  app.register('/help','get',(req, res) => {
    res.send("This is the help section")
  }),
  app.register('/help','post',(req, res) => {
    res.send("This is the help section")
  })}

module.exports = {
  registerHelp
}

In the main file, bootstrap both.

app.js

require('./server').startServer(7000)
require('./web/help').registerHelp()

You can use the key argument in sorted() method unless you have two same values in list2.

The code is given below:

sorted(list2, key = lambda x: list1[list2.index(x)]) 

It sorts list2 according to corresponding values in list1, but make sure that while using this, no two values in list2 evaluate to be equal because list.index() function give the first value

Here is a filter that use:

app.filter('milliSecondsToTimeCode', function () {
    return function msToTime(duration) {
        var milliseconds = parseInt((duration % 1000) / 100)
            , seconds = parseInt((duration / 1000) % 60)
            , minutes = parseInt((duration / (1000 * 60)) % 60)
            , hours = parseInt((duration / (1000 * 60 * 60)) % 24);

        hours = (hours < 10) ? "0" + hours : hours;
        minutes = (minutes < 10) ? "0" + minutes : minutes;
        seconds = (seconds < 10) ? "0" + seconds : seconds;

        return hours + ":" + minutes + ":" + seconds + "." + milliseconds;
    };
});

Just add it to your expression as such

{{milliseconds | milliSecondsToTimeCode}}

I've had a similar issue with this error. In my case, I was entering the incorrect password for the Keystore.

I changed the password for the Keystore to match what I was entering (I didn't want to change the password I was entering), but it still gave the same error.

keytool -storepasswd -keystore keystore.jks

Problem was that I also needed to change the Key's password within the Keystore.

When I initially created the Keystore, the Key was created with the same password as the Keystore (I accepted this default option). So I had to also change the Key's password as follows:

keytool -keypasswd  -alias my.alias -keystore keystore.jks

As far as I know, an input element may not have a href attribute, which is where Fancybox gets its information about the content. The following code uses an a element instead of the input element. Also, this is what I would call the "standard way".

The trick is defining the masksToBounds property of your view's layer properly:

view.layer.masksToBounds = NO;

and it should work.

(Source)

When numbers, dates and times are formatted into strings or parsed from strings a culture is used to determine how it is done. E.g. in the dominant en-US culture you have these string representations:

• 1,000,000.00 - one million with a two digit fraction
• 1/29/2013 - date of this posting

In my culture (da-DK) the values have this string representation:

• 1.000.000,00 - one million with a two digit fraction
• 29-01-2013 - date of this posting

In the Windows operating system the user may even customize how numbers and date/times are formatted and may also choose another culture than the culture of his operating system. The formatting used is the choice of the user which is how it should be.

So when you format a value to be displayed to the user using for instance ToString or String.Format or parsed from a string using DateTime.Parse or Decimal.Parse the default is to use the CultureInfo.CurrentCulture. This allows the user to control the formatting.

However, a lot of string formatting and parsing is actually not strings exchanged between the application and the user but between the application and some data format (e.g. an XML or CSV file). In that case you don't want to use CultureInfo.CurrentCulture because if formatting and parsing is done with different cultures it can break. In that case you want to use CultureInfo.InvariantCulture (which is based on the en-US culture). This ensures that the values can roundtrip without problems.

The reason that ReSharper gives you the warning is that some application writers are unaware of this distinction which may lead to unintended results but they never discover this because their CultureInfo.CurrentCulture is en-US which has the same behavior as CultureInfo.InvariantCulture. However, as soon as the application is used in another culture where there is a chance of using one culture for formatting and another for parsing the application may break.

So to sum it up:

• Use CultureInfo.CurrentCulture (the default) if you are formatting or parsing a user string.
• Use CultureInfo.InvariantCulture if you are formatting or parsing a string that should be parseable by a piece of software.
• Rarely use a specific national culture because the user is unable to control how formatting and parsing is done.

you can simply write:

for item,i in zip(your_list, range(len(your_list)):

    if type(item) == list:
        print(f"{item} at index {i} is a list")

The recommended approach in this case is to sort the data in the database, adding an ORDER BY at the end of the query that fetches the results, something like this:

SELECT temperature FROM temperatures ORDER BY temperature ASC;  -- ascending order
SELECT temperature FROM temperatures ORDER BY temperature DESC; -- descending order

If for some reason that is not an option, you can change the sorting order like this in Python:

templist = [25, 50, 100, 150, 200, 250, 300, 33]
sorted(templist, key=int)               # ascending order
> [25, 33, 50, 100, 150, 200, 250, 300]
sorted(templist, key=int, reverse=True) # descending order
> [300, 250, 200, 150, 100, 50, 33, 25]

As has been pointed in the comments, the int key (or float if values with decimals are being stored) is required for correctly sorting the data if the data received is of type string, but it'd be very strange to store temperature values as strings, if that is the case, go back and fix the problem at the root, and make sure that the temperatures being stored are numbers.

it is wrong. correct will be

P3 P2 P4 P5 P1 0 3 4 6 10 as the correct difference are these

Waiting Time (0+3+4+6+10)/5 = 4.6

Since Bootstrap 3 removed the submenu part and we need to adapt ourselves the style, I think it's better to go with SmartMenu Bootstrap: https://vadikom.github.io/smartmenus/src/demo/bootstrap-navbar.html#

That would save us time on mobile responsive and style.

This plugin also very promising.

The most efficient and easy way:

list(data_set.to_records())

You can filter the columns you need before this call.

Use the -printcert command like this:

keytool -printcert -file certificate.pem

I have tried some hours now and the easiest way to stop browsers to jump to the anchor instead of scrolling to it is: Using another anchor (an id you do not use on the site). So instead of linking to "http://#YourActualID" you link to "http://#NoIDonYourSite". Poof, browsers won’t jump anymore.

Then just check if an anchor is set (with the script provided below, that is pulled out of the other thread!). And set your actual id you want to scroll to.

$(document).ready(function(){


  $(window).load(function(){
    // Remove the # from the hash, as different browsers may or may not include it
    var hash = location.hash.replace('#','');

    if(hash != ''){

       // Clear the hash in the URL
       // location.hash = '';   // delete front "//" if you want to change the address bar
        $('html, body').animate({ scrollTop: $('#YourIDtoScrollTo').offset().top}, 1000);

       }
   });
});

See https://lightningsoul.com/media/article/coding/30/YOUTUBE-SOCKREAD-SCRIPT-FOR-MIRC#content for a working example.

There is no concept of interface in C++,
You can simulate the behavior using an Abstract class.
Abstract class is a class which has atleast one pure virtual function, One cannot create any instances of an abstract class but You could create pointers and references to it. Also each class inheriting from the abstract class must implement the pure virtual functions in order that it's instances can be created.

You can't. That's because that's what browsers were designed to do: Serve content. But you can make it harder to download.

First thing's first, you could disable the contextmenu event, aka "the right click". That would prevent your regular skiddie from blatantly ripping your video by right clicking and Save As. But then they could just disable JS and get around this or find the video source via the browser's debugger. Plus this is bad UX. There are lots of legitimate things in a context menu than just Save As.

You could also use custom video player libraries. Most of them implement video players that customize the context menu to your liking. So you don't get the default browser context menu. And if ever they do serve a menu item similar to Save As, you can disable it. But again, this is a JS workaround. Weaknesses are similar to the previous option.

Another way to do it is to serve the video using HTTP Live Streaming. What it essentially does is chop up the video into chunks and serve it one after the other. This is how most streaming sites serve video. So even if you manage to Save As, you only save a chunk, not the whole video. It would take a bit more effort to gather all the chunks and stitch them using some dedicated software.

Another technique is to paint <video> on <canvas>. In this technique, with a bit of JavaScript, what you see on the page is a <canvas> element rendering frames from a hidden <video>. And because it's a <canvas>, the context menu will use an <img>'s menu, not a <video>'s. You'll get a Save Image As instead of a Save Video As.

You could also use CSRF tokens to your advantage. You'd have your sever send down a token on the page. You then use that token to fetch your video. Your server checks to see if it's a valid token before it serves the video, or get an HTTP 401. The idea is that you can only ever get a video by having a token which you can only ever get if you came from the page, not directly visiting the video url.

At the end of the day, I'd just upload my video to a third-party video site, like YouTube or Vimeo. They have good video management tools, optimizes playback to the device, and they make efforts in preventing their videos from being ripped with zero effort on your end.

check window.history.length or simply, history.length

EDIT: some browsers start their history with 0, others with 1. adjust accordingly.

if it has a value of 1, it means it's the first page in that window/tab - then you can have JS redirect you.

<script>
    function backAway(){
        //if it was the first page
        if(history.length === 1){
            window.location = "http://www.mysite.com/"
        } else {
            history.back();
        }
    }
</script>

<a href="#" onClick="backAway()">Back</a>

Using SVN 1.8, deleting lock file does not help (lock file does not exists).

Refresh/Cleanup did not solve either.

What did solve:

1) Backup your directory, just incase...
2) Team... Disconnect. Choose to remove .svn files
3) Add it again to SVN.

Note: In my case, error was due to loss of network connection during initial commit.

Once you do this

new Date(dateString).getTime() / 1000

It is already UTC time stamp

   const getUnixTimeUtc = (dateString = new Date()) => Math.round(new Date(dateString).getTime() / 1000)

I tested on https://www.unixtimestamp.com/index.php

NVM Installation & usage on Windows

Below are the steps for NVM Installation on Windows:

NVM stands for node version manager, which will help to switch the your node versions for specific use. It also allows the user to work with multiple npm and node versions.

Install nvm setup. Use command "nvm list" to check list ofinstalled node version. Type "nvm use version number[6.9.3]" to switch versions. For more info

Lets suppose you have N elements in a heap. Then its height would be Log(N)

Now you want to insert another element, then the complexity would be : Log(N), we have to compare all the way UP to the root.

Now you are having N+1 elements & height = Log(N+1)

Using induction technique it can be proved that the complexity of insertion would be ?logi.

Now using

log a + log b = log ab

This simplifies to : ?logi=log(n!)

which is actually O(NlogN)

But

we are doing something wrong here, as in all the case we do not reach at the top. Hence while executing most of the times we may find that, we are not going even half way up the tree. Whence, this bound can be optimized to have another tighter bound by using mathematics given in answers above.

This realization came to me after a detail though & experimentation on Heaps.

If the list of N numbers from 1 to N is randomly generated, then yes, there is a possibility that some numbers may be repeated.

If you want a list of numbers from 1 to N in a random order, fill an array with integers from 1 to N, and then use a Fisher-Yates shuffle or Python's random.shuffle().

I had the same issue. I'm running a java rest app on a jboss server. But I think the solution is similar on an ASP .NET webapp.

Firefox makes a pre call to your server / rest url to check which options are allowed. That is the "OPTIONS" request which your server doesn't reply to accordingly. If this OPTIONS call is replied correct a second call is performed which is the actual "POST" request with json content.

This only happens when performing a cross-domain call. In your case calling 'http://localhost:16329/Hello' instead of calling a url path under the same domain '/Hello'

If you intend to make a cross domain call you have to enhance your rest service class with an annotated method the supports a "OPTIONS" http request. This is the according java implementation:

@Path("/rest")
public class RestfulService {

    @POST
    @Path("/Hello")
    @Consumes(MediaType.APPLICATION_JSON)
    @Produces(MediaType.TEXT_PLAIN)
    public string HelloWorld(string name)
    {
        return "hello, " + name;
    }

//THIS NEEDS TO BE ADDED ADDITIONALLY IF MAKING CROSS-DOMAIN CALLS

    @OPTIONS
    @Path("/Hello")
    @Produces(MediaType.TEXT_PLAIN+ ";charset=utf-8")
    public Response checkOptions(){
        return Response.status(200)
        .header("Access-Control-Allow-Origin", "*")
        .header("Access-Control-Allow-Headers", "Content-Type")
        .header("Access-Control-Allow-Methods", "POST, OPTIONS") //CAN BE ENHANCED WITH OTHER HTTP CALL METHODS 
        .build();
    }
}

So I guess in .NET you have to add an additional method annotated with

[WebInvoke(
        Method = "OPTIONS",
        UriTemplate = "Hello",
        ResponseFormat = WebMessageFormat.)]

where the following headers are set

.header("Access-Control-Allow-Origin", "*")
        .header("Access-Control-Allow-Headers", "Content-Type")
        .header("Access-Control-Allow-Methods", "POST, OPTIONS")

In python there are no arrays, lists are used instead. There are various ways to delete an object from a list:

my_list = [1,2,4,6,7]

del my_list[1] # Removes index 1 from the list
print my_list # [1,4,6,7]
my_list.remove(4) # Removes the integer 4 from the list, not the index 4
print my_list # [1,6,7]
my_list.pop(2) # Removes index 2 from the list

In your case the appropriate method to use is pop, because it takes the index to be removed:

x = object()
y = object()
array = [x, y]
array.pop(0)
# Using the del statement
del array[0]

1. Copy the contents of the file,
2. Create an .h file, give it the name of the original .h file
3. Copy the contents of the original file to the newly created one
4. Build it
5. VOILA!!

In my particular case -g -march=armv7-a -mfloat-abi=hard -mfpu=neon -marm -mthumb-interwork worked.

http://maven.apache.org/guides/mini/guide-using-one-source-directory.html

<build>
<sourceDirectory>../src/main/java</sourceDirectory>

also see

Maven compile with multiple src directories

def test():
    ....
    return r1, r2, r3, ....

>> ret_val = test()
>> print ret_val
(r1, r2, r3, ....)

now you can do everything you like with your tuple.

Sorry to bump an old question but the answer is to count the character length of the cell and not its value.

CellCount = Cells(Row, 10).Value
If Len(CellCount) <= "13" Then
'do something
End If

hope that helps. Cheers

Update: you can read the more complex answer, which contains more methods and information.

There exists a couple of scripts, which can be used as simple package managers. But as far as I know, none of them allows you to upgrade packages, because it’s not an easy task on Windows since there is not possible to overwrite files in use. So you have to close all Cygwin instances first and then you can use Cygwin’s native setup.exe (which itself does the upgrade via “replace after reboot” method, when files are in use).

apt-cyg

The best one for me. Simply because it’s one of the most recent. It works correctly for both platforms - x86 and x86_64. There exists a lot of forks with some additional features. For example the kou1okada fork is one of improved versions.

Cygwin’s setup.exe

It has also command line mode. Moreover it allows you to upgrade all installed packages at once.

setup.exe-x86_64.exe -q --packages=bash,vim

Example use:

setup.exe-x86_64.exe -q --packages="bash,vim"

You can create an alias for easier use, for example:

alias cyg-get="/cygdrive/d/path/to/cygwin/setup-x86_64.exe -q -P"

Then you can for example install the Vim package with:

cyg-get vim

goto begin and end of all parents closures

var foo=false;
var loop1=true;
LABEL1: do {var LABEL1GOTO=false;
    console.log("here be 2 times");
    if (foo==false){
        foo=true;
        LABEL1GOTO=true;continue LABEL1;// goto up
    }else{
        break LABEL1; //goto down
    }
    console.log("newer go here");
} while(LABEL1GOTO);

you need to give the path. Atleast you should give the path from the current directory. It will work for sure. ./filename

Using git rm --cached *file* is not working fine for me (I'm aware this question is 8 years old, but it still shows at the top of the search for this topic), it does remove the file from the index, but it also deletes the file from the remote.

I have no idea why that is. All I wanted was keeping my local config isolated (otherwise I had to comment the localhost base url before every commit), not delete the remote equivalent to config.

Reading some more I found what seems to be the proper way to do this, and the only way that did what I needed, although it does require more attention, especially during merges.

Anyway, all it requires is git update-index --assume-unchanged *path/to/file*.

As far as I understand, this is the most notable thing to keep in mind:

Git will fail (gracefully) in case it needs to modify this file in the index e.g. when merging in a commit; thus, in case the assumed-untracked file is changed upstream, you will need to handle the situation manually.

-> Testing the app with maximum number of user and input is defined as load testing. While testing the app with more than maximum number of user and input is defined as stress testing.

->In Load testing we measure the system performance based on a volume of users. While in Stress testing we measure the breakpoint of a system.

->Load Testing is testing the application for a given load requirements which may include any of the following criteria:

 .Total number of users.

 .Response Time

 .Through Put

Some parameters to check State of servers/application.

-> While stress testing is testing the application for unexpected load. It includes

 .Vusers

 .Think-Time

Example:

If an app is build for 500 users, then for load testing we check up to 500 users and for stress testing we check greater than 500.

import datetime

timestamp = datetime.datetime.fromtimestamp(1500000000)

print(timestamp.strftime('%Y-%m-%d %H:%M:%S'))

This will give the output:

2017-07-14 08:10:00

SIGABRT is, as stated in other answers, a general uncaught exception. You should definitely learn a little bit more about Objective-C. The problem is probably in your UITableViewDelegate method didSelectRowAtIndexPath.

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath

I can't tell you much more until you show us something of the code where you handle the table data source and delegate methods.

Synchronized Vs Atomic Vs Volatile:

• Volatile and Atomic is apply only on variable , While Synchronized apply on method.
• Volatile ensure about visibility not atomicity/consistency of object , While other both ensure about visibility and atomicity.
• Volatile variable store in RAM and it’s faster in access but we can’t achive Thread safety or synchronization whitout synchronized keyword.
• Synchronized implemented as synchronized block or synchronized method while both not. We can thread safe multiple line of code with help of synchronized keyword while with both we can’t achieve the same.
• Synchronized can lock the same class object or different class object while both can’t.

Please correct me if anything i missed.

The question did not state precisely what output is expected but assuming that for month you want the month number (January = 1) and for the year you want the numeric 4 digit year then assuming that we have just run the code in the question:

cycle(date1)
## [1] 3
as.integer(date1)
## [1] 2012

You can use the function int atoi (const char * str);.
You need to include #include <stdlib.h> and use the function in this way:
int x = atoi(argv[1]);
Here more information if needed: atoi - C++ Reference

May this code help you. It works in my case.
