The only way to get the iOS dictation is to sign up yourself through Nuance: http://dragonmobile.nuancemobiledeveloper.com/ - it's expensive, because it's the best. Presumably, Apple's contract prevents them from exposing an API.

The built in iOS accessibility features allow immobilized users to access dictation (and other keyboard buttons) through tools like VoiceOver and Assistive Touch. It may not be worth reinventing this if your users might be familiar with these tools.

I successfully implemented my Speech-Service with offline capabilities by using onPartialResults when offline and onResults when online.

We don't need to plt.ioff() or plt.show() (if we use %matplotlib inline). You can test above code without plt.ioff(). plt.close() has the essential role. Try this one:

%matplotlib inline
import pylab as plt

# It doesn't matter you add line below. You can even replace it by 'plt.ion()', but you will see no changes.
## plt.ioff()

# Create a new figure, plot into it, then close it so it never gets displayed
fig = plt.figure()
plt.plot([1,2,3])
plt.savefig('test0.png')
plt.close(fig)

# Create a new figure, plot into it, then don't close it so it does get displayed
fig2 = plt.figure()
plt.plot([1,3,2])
plt.savefig('test1.png')

If you run this code in iPython, it will display a second plot, and if you add plt.close(fig2) to the end of it, you will see nothing.

In conclusion, if you close figure by plt.close(fig), it won't be displayed.

If you don't want to calculate it using java's Calendar you can use Androids Time class It is supposed to be faster but I didn't notice much difference when i switched.

I could not find any pre-defined functions to determine time between 2 dates for an age in Android. There are some nice helper functions to get formatted time between dates in the DateUtils but that's probably not what you want.

I cannot quickly reproduce the symptoms: if I try myscript '"test"' with a batch file myscript.bat containing just @echo.%1 or even @echo.%~1, I get all quotes: '"test"'

Perhaps you can try the escape character ^ like this: myscript '^"test^"'?

Extract each jar to it's own directory using the jar command with parameters xvf. i.e. jar xvf myjar.jar for each jar.

Then, use the UNIX command diff to compare the two directories. This will show the differences in the directories. You can use diff -r dir1 dir2 two recurse and show the differences in text files in each directory(.xml, .properties, etc).

This will also show if binary class files differ. To actually compare the class files you will have to decompile them as noted by others.

class CurrentValue:

    def __init__(self, value):
        self.value = value

    def set_val(self, k):
        self.value = k

    def get_val(self):
        return self.value


class AddValue:

    def av(self, ocv):
        print('Before:', ocv.get_val())
        num = int(input('Enter number to add : '))
        nnum = num + ocv.get_val()
        ocv.set_val(nnum)
        print('After add :', ocv.get_val())


cvo = CurrentValue(5)

avo = AddValue()

avo.av(cvo)

We define 2 classes, CurrentValue and AddValue We define 3 methods in the first class One init in order to give to the instance variable self.value an initial value A set_val method where we set the self.value to a k A get_val method where we get the valuue of self.value We define one method in the second class A av method where we pass as parameter(ovc) an object of the first class We create an instance (cvo) of the first class We create an instance (avo) of the second class We call the method avo.av(cvo) of the second class and pass as an argument the object we have already created from the first class. So by this way I would like to show how it is possible to call a method of a class from another class.

I am sorry for any inconvenience. This will not happen again.

This is actually a very difficult problem (mathematically), and I'm working on the same thing almost. I asked a similar question on Stackoverflow but got no response, but posted in DocType (StackOverflow for HTML/CSS) and got a response. Check it out http://doctype.com/javascript-image-zoom-css3-transforms-calculate-origin-example

I'm in the middle of building a jQuery plugin that does this (Google Maps style zoom using CSS3 Transforms). I've got the zoom to mouse cursor bit working fine, still trying to figure out how to allow the user to drag the canvas around like you can do in Google Maps. When I get it working I'll post code here, but check out above link for the mouse-zoom-to-point part.

I didn't realise there was scale and translate methods on Canvas context, you can achieve the same thing using CSS3 eg. using jQuery:

$('div.canvasContainer > canvas')
    .css('-moz-transform', 'scale(1) translate(0px, 0px)')
    .css('-webkit-transform', 'scale(1) translate(0px, 0px)')
    .css('-o-transform', 'scale(1) translate(0px, 0px)')
    .css('transform', 'scale(1) translate(0px, 0px)');

Make sure you set the CSS3 transform-origin to 0, 0 (-moz-transform-origin: 0 0). Using CSS3 transform allows you to zoom in on anything, just make sure the container DIV is set to overflow: hidden to stop the zoomed edges spilling out of the sides.

Whether you use CSS3 transforms, or canvas' own scale and translate methods is upto you, but check the above link for the calculations.

Update: Meh! I'll just post the code here rather than get you to follow a link:

$(document).ready(function()
{
    var scale = 1;  // scale of the image
    var xLast = 0;  // last x location on the screen
    var yLast = 0;  // last y location on the screen
    var xImage = 0; // last x location on the image
    var yImage = 0; // last y location on the image

    // if mousewheel is moved
    $("#mosaicContainer").mousewheel(function(e, delta)
    {
        // find current location on screen 
        var xScreen = e.pageX - $(this).offset().left;
        var yScreen = e.pageY - $(this).offset().top;

        // find current location on the image at the current scale
        xImage = xImage + ((xScreen - xLast) / scale);
        yImage = yImage + ((yScreen - yLast) / scale);

        // determine the new scale
        if (delta > 0)
        {
            scale *= 2;
        }
        else
        {
            scale /= 2;
        }
        scale = scale < 1 ? 1 : (scale > 64 ? 64 : scale);

        // determine the location on the screen at the new scale
        var xNew = (xScreen - xImage) / scale;
        var yNew = (yScreen - yImage) / scale;

        // save the current screen location
        xLast = xScreen;
        yLast = yScreen;

        // redraw
        $(this).find('div').css('-moz-transform', 'scale(' + scale + ')' + 'translate(' + xNew + 'px, ' + yNew + 'px' + ')')
                           .css('-moz-transform-origin', xImage + 'px ' + yImage + 'px')
        return false;
    });
});

You will of course need to adapt it to use the canvas scale and translate methods.

Update 2: Just noticed I'm using transform-origin together with translate. I've managed to implement a version that just uses scale and translate on their own, check it out here http://www.dominicpettifer.co.uk/Files/Mosaic/MosaicTest.html Wait for the images to download then use your mouse wheel to zoom, also supports panning by dragging the image around. It's using CSS3 Transforms but you should be able to use the same calculations for your Canvas.

Use Manatee.Json https://github.com/gregsdennis/Manatee.Json/wiki/Usage

And you can convert the entire object to a string, filename.json is expected to be located in documents folder.

        var text = File.ReadAllText("filename.json");
        var json = JsonValue.Parse(text);

        while (JsonValue.Null != null)
        {
            Console.WriteLine(json.ToString());

        }
        Console.ReadLine();

If you're not wanting to save changes set savechanges to false

    Sub CloseBook2()
        ActiveWorkbook.Close savechanges:=False
    End Sub

for more examples, http://support.microsoft.com/kb/213428 and i believe in the past I've just used

    ActiveWorkbook.Close False

I suppose you're getting this JSON from a server or a file, and you want to create a JSONArray object out of it.

String strJSON = ""; // your string goes here
JSONArray jArray = (JSONArray) new JSONTokener(strJSON).nextValue();
// once you get the array, you may check items like
JSONOBject jObject = jArray.getJSONObject(0);

Hope this helps :)

You can't run two SQL statements into one like you are doing.

You can't "execute" a select query.

db is an object and you haven't set it to anything: (e.g. set db = currentdb)

In VBA integer types can hold up to max of 32767 - I would be tempted to use Long.

You might want to be a bit more specific about the date you are inserting:

INSERT INTO Test (Start_Date) VALUES ('#" & format(InDate, "mm/dd/yyyy") & "#' );"

If you need this for PHP:

The PHP DOM functions won't work properly unless it is properly formatted XML. No matter how much better their use is for the rest of mankind.

simplehtmldom is good, but I found it a bit buggy, and it is is quite memory heavy [Will crash on large pages.]

I have never used querypath, so can't comment on its usefulness.

Another one to try is my DOMParser which is very light on resources and I've been using happily for a while. Simple to learn & powerful.

For Python and Java, similar links were posted.

For the downvoters - I only wrote my class when the XML parsers proved unable to withstand real use. Religious downvoting just prevents useful answers from being posted - keep things within perspective of the question, please.

The problem is on this line:

oShell.run "cmd.exe /C copy "S:Claims\Sound.wav" "C:\WINDOWS\Media\Sound.wav"

Your first quote next to "S:Claims" ends the string; you need to escape the quotes around your files with a second quote, like this:

oShell.run "cmd.exe /C copy ""S:\Claims\Sound.wav"" ""C:\WINDOWS\Media\Sound.wav"" "

You also have a typo in S:Claims\Sound.wav, should be S:\Claims\Sound.wav.

I also assume the apostrophe before Dim oShell and after Set oShell = Nothing are typos as well.

You can set the s bit for your script so that it does not need sudo and runs as root (and you do not need to write your root password in the script):

sudo chmod +s myscript

You have broken version of RVM. Ubuntu does something to RVM that produces lots of errors, the only safe way of fixing for now is to:

sudo apt-get --purge remove ruby-rvm
sudo rm -rf /usr/share/ruby-rvm /etc/rvmrc /etc/profile.d/rvm.sh

open new terminal and validate environment is clean from old RVM settings (should be no output):

env | grep rvm

if there was output, try to open new terminal, if it does not help then restart your computer.

install RVM:

\curl -L https://get.rvm.io | 
  bash -s stable --ruby --autolibs=enable --auto-dotfiles

If you find you need some hand-holding, take a look at Installing Ruby on Ubuntu 12.04, which gives a bit more explanation.

I have used a Wrapper to get around this problem. Create a wrapper object and pass your mocked method.

See Mocking Static Methods for Unit Testing by Paul Irwin, it has nice examples.

In docker-compose.yml you can use this format:

Yes! there is a way to use a variable as a pointer in python!

I am sorry to say that many of answers were partially wrong. In principle every equal(=) assignation shares the memory address (check the id(obj) function), but in practice it is not such. There are variables whose equal("=") behaviour works in last term as a copy of memory space, mostly in simple objects (e.g. "int" object), and others in which not (e.g. "list","dict" objects).

Here is an example of pointer assignation

dict1 = {'first':'hello', 'second':'world'}
dict2 = dict1 # pointer assignation mechanism
dict2['first'] = 'bye'
dict1
>>> {'first':'bye', 'second':'world'}

Here is an example of copy assignation

a = 1
b = a # copy of memory mechanism. up to here id(a) == id(b)
b = 2 # new address generation. therefore without pointer behaviour
a
>>> 1

Pointer assignation is a pretty useful tool for aliasing without the waste of extra memory, in certain situations for performing comfy code,

class cls_X():
   ...
   def method_1():
      pd1 = self.obj_clsY.dict_vars_for_clsX['meth1'] # pointer dict 1: aliasing
      pd1['var4'] = self.method2(pd1['var1'], pd1['var2'], pd1['var3'])
   #enddef method_1
   ...
#endclass cls_X

but one have to be aware of this use in order to prevent code mistakes.

To conclude, by default some variables are barenames (simple objects like int, float, str,...), and some are pointers when assigned between them (e.g. dict1 = dict2). How to recognize them? just try this experiment with them. In IDEs with variable explorer panel usually appears to be the memory address ("@axbbbbbb...") in the definition of pointer-mechanism objects.

I suggest investigate in the topic. There are many people who know much more about this topic for sure. (see "ctypes" module). I hope it is helpful. Enjoy the good use of the objects! Regards, José Crespo

You actually can't manually "free" memory in C, in the sense that the memory is released from the process back to the OS ... when you call malloc(), the underlying libc-runtime will request from the OS a memory region. On Linux, this may be done though a relatively "heavy" call like mmap(). Once this memory region is mapped to your program, there is a linked-list setup called the "free store" that manages this allocated memory region. When you call malloc(), it quickly looks though the free-store for a free block of memory at the size requested. It then adjusts the linked list to reflect that there has been a chunk of memory taken out of the originally allocated memory pool. When you call free() the memory block is placed back in the free-store as a linked-list node that indicates its an available chunk of memory.

If you request more memory than what is located in the free-store, the libc-runtime will again request more memory from the OS up to the limit of the OS's ability to allocate memory for running processes. When you free memory though, it's not returned back to the OS ... it's typically recycled back into the free-store where it can be used again by another call to malloc(). Thus, if you make a lot of calls to malloc() and free() with varying memory size requests, it could, in theory, cause a condition called "memory fragmentation", where there is enough space in the free-store to allocate your requested memory block, but not enough contiguous space for the size of the block you've requested. Thus the call to malloc() fails, and you're effectively "out-of-memory" even though there may be plenty of memory available as a total amount of bytes in the free-store.

Answering normajeans' question about setting default value. Create a defaults object with same properties and merge with the arguments object

If using ES6:

    function yourFunction(args){
        let defaults = {opt1: true, opt2: 'something'};
        let params = {...defaults, ...args}; // right-most object overwrites 
        console.log(params.opt1);
    }

Older Browsers using Object.assign(target, source):

    function yourFunction(args){
        var defaults = {opt1: true, opt2: 'something'};
        var params = Object.assign(defaults, args) // args overwrites as it is source
        console.log(params.opt1);
    }

You have to start a service in your Application class to run it always. If you do that, your service will be always running. Even though user terminates your app from task manager or force stop your app, it will start running again.

Create a service:

public class YourService extends Service {

    @Nullable
    @Override
    public IBinder onBind(Intent intent) {
        return null;
    }

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        // do your jobs here
        return super.onStartCommand(intent, flags, startId);
    }
}

Create an Application class and start your service:

public class App extends Application {

    @Override
    public void onCreate() {
        super.onCreate();

        startService(new Intent(this, YourService.class));
    }
}

Add "name" attribute into the "application" tag of your AndroidManifest.xml

android:name=".App"

Also, don't forget to add your service in the "application" tag of your AndroidManifest.xml

<service android:name=".YourService"/>

And also this permission request in the "manifest" tag (if API level 28 or higher):

<uses-permission android:name="android.permission.FOREGROUND_SERVICE"/>

UPDATE

After Android Oreo, Google introduced some background limitations. Therefore, this solution above won't work probably. When a user kills your app from task manager, Android System will kill your service as well. If you want to run a service which is always alive in the background. You have to run a foreground service with showing an ongoing notification. So, edit your service like below.

public class YourService extends Service {

    private static final int NOTIF_ID = 1;
    private static final String NOTIF_CHANNEL_ID = "Channel_Id";

    @Nullable
    @Override
    public IBinder onBind(Intent intent) {
        return null;
    }

    @Override
    public int onStartCommand(Intent intent, int flags, int startId){

        // do your jobs here

        startForeground();
        
        return super.onStartCommand(intent, flags, startId);
    }

    private void startForeground() {
        Intent notificationIntent = new Intent(this, MainActivity.class);

        PendingIntent pendingIntent = PendingIntent.getActivity(this, 0,
                notificationIntent, 0);

        startForeground(NOTIF_ID, new NotificationCompat.Builder(this, 
                NOTIF_CHANNEL_ID) // don't forget create a notification channel first
                .setOngoing(true)
                .setSmallIcon(R.drawable.ic_notification)
                .setContentTitle(getString(R.string.app_name))
                .setContentText("Service is running background")
                .setContentIntent(pendingIntent)
                .build());         
    }
}

EDIT: RESTRICTED OEMS

Unfortunately, some OEMs (Xiaomi, OnePlus, Samsung, Huawei etc.) restrict background operations due to provide longer battery life. There is no proper solution for these OEMs. Users need to allow some special permissions that are specific for OEMs or they need to add your app into whitelisted app list by device settings. You can find more detail information from https://dontkillmyapp.com/.

If background operations are an obligation for you, you need to explain it to your users why your feature is not working and how they can enable your feature by allowing those permissions. I suggest you to use AutoStarter library (https://github.com/judemanutd/AutoStarter) in order to redirect your users regarding permissions page easily from your app.

By the way, if you need to run some periodic work instead of having continuous background job. You better take a look WorkManager (https://developer.android.com/topic/libraries/architecture/workmanager)

As has been mentioned, slicing with None or with np.newaxes is a great way to do this. Another alternative is to use transposes and broadcasting, as in

(data.T - vector).T

and

(data.T / vector).T

For higher dimensional arrays you may want to use the swapaxes method of NumPy arrays or the NumPy rollaxis function. There really are a lot of ways to do this.

For a fuller explanation of broadcasting, see http://docs.scipy.org/doc/numpy/user/basics.broadcasting.html

        let modelURL = NSBundle.mainBundle().URLForResource("some string", withExtension: "mom")
        let mom = NSManagedObjectModel(contentsOfURL: modelURL)

        for entityName in mom.entitiesByName.keys {
            let fr = NSFetchRequest(entityName: entityName as String)
            let a = Utility.managedObjectContext().executeFetchRequest(fr, error: nil) as [NSManagedObject]
            for mo in a {
                Utility.managedObjectContext().deleteObject(mo)
            }
        }

        Utility.managedObjectContext().save(nil)
    }

It sounds like your table has no key. You should be able to simply try the INSERT: if it’s a duplicate then the key constraint will bite and the INSERT will fail. No worries: you just need to ensure the application doesn't see/ignores the error. When you say 'primary key' you presumably mean IDENTITY value. That's all very well but you also need a key constraint (e.g. UNIQUE) on your natural key.

Also, I wonder whether your procedure is doing too much. Consider having separate procedures for 'create' and 'read' actions respectively.

This is what worked for me:

$.get({
    method: 'GET',
    url: 'api.php',
    headers: {
        'Content-Type': 'application/json',
    },
    // query parameters go under "data" as an Object
    data: {
        client: 'mikescafe'
    }
});

will make a REST/AJAX call - > GET http://localhost:3000/api.php?client=mikescafe

Good Luck.

I would try to solve this without VBA. Just select this space and use replace (change to nothing) on that worksheet you're trying to get rid off those spaces.

If you really want to use VBA I believe you could select first character

strSpace = left(range("A1").Value,1)

and use replace function in VBA the same way

Range("A1").Value = Replace(Range("A1").Value, strSpace, "")

or

for each cell in selection.cells
 cell.value = replace(cell.value, strSpace, "")
next

You have to use bracket notation:

var obj = {};
obj[a[i]] = 0;
x.push(obj);

The result will be:

x = [{left: 0}, {top: 0}];

Maybe instead of an array of objects, you just want one object with two properties:

var x = {};

and

x[a[i]] = 0;

This will result in x = {left: 0, top: 0}.

As already pointed out by others, all the solutions above only change the working directory of the current process. This is lost when you exit back to the Unix shell. If desperate you can change the parent shell directory on Unix with this horrible hack:

def quote_against_shell_expansion(s):
    import pipes
    return pipes.quote(s)

def put_text_back_into_terminal_input_buffer(text):
    # use of this means that it only works in an interactive session
    # (and if the user types while it runs they could insert characters between the characters in 'text'!)
    import fcntl, termios
    for c in text:
        fcntl.ioctl(1, termios.TIOCSTI, c)

def change_parent_process_directory(dest):
    # the horror
    put_text_back_into_terminal_input_buffer("cd "+quote_against_shell_expansion(dest)+"\n")

this will give you result that has the minimum price on all records.

SELECT *
FROM pieces
WHERE price =  ( SELECT MIN(price) FROM pieces )

Another way is using set data type.

Some characteristic of Sets: Sets are unordered, can include mixed data types, elements in a set cannot be repeated, are mutable.

Solving your question:

df = pd.DataFrame({'A':[1,1,3,2,6,2,8]})
sorted(set(df.A))

The answer in List type:

[1, 2, 3, 6, 8]

python supports arbitrarily large integers naturally:

In [1]: 59**3*61**4*2*3*5*7*3*5*7
Out[1]: 62702371781194950
In [2]: _ % 61**4
Out[2]: 0

Create CustomerDTO Object every time inside while loop

Check the below code

    while (rs.next()) {

    Customer customer = new Customer();

    customer.setId(rs.getInt("id"));
    customer.setName(rs.getString("name"));
    customer.setAddress(rs.getString("address"));
    customer.setPhone(rs.getString("phone"));
    customer.setEmail(rs.getString("email"));
    customer.setBountPoints(rs.getInt("bonuspoint"));
    customer.setTotalsale(rs.getInt("totalsale"));

    customers.add(customer);
}

If, for example, x = 5 and is stored as string, you can also just:

x = x + 0

and the new x would be stored as a numeric value.

Companies use their reversed Internet domain name to begin their package names—for example, com.example.mypackage for a package named mypackage created by a programmer at example.com.

Name collisions that occur within a single company need to be handled by convention within that company, perhaps by including the region or the project name after the company name (for example, com.example.region.mypackage).

If you have a company domain www.example.com

Then you should use:

com.example.region.projectname

If you own a domain name like example.co.uk than it should be:

uk.co.example.region.projectname

If you do not own a domain, you should then use your email address:

for [email protected] it should be:

com.example.name.region.projectname

One cannot disable the browser back button functionality. The only thing that can be done is prevent them.

The below JavaScript code needs to be placed in the head section of the page where you don’t want the user to revisit using the back button:

<script>
    function preventBack() {
        window.history.forward();
    }

    setTimeout("preventBack()", 0);
    window.onunload = function() {
        null
    };
</script>

Suppose there are two pages Page1.php and Page2.php and Page1.php redirects to Page2.php.

Hence to prevent user from visiting Page1.php using the back button you will need to place the above script in the head section of Page1.php.

After generation of woff files, you have to define font-family, which can be used later in all your css styles. Below is the code to define font families (for normal, bold, bold-italic, italic) typefaces. It is assumed, that there are 4 *.woff files (for mentioned typefaces), placed in fonts subdirectory.

In CSS code:

@font-face {
    font-family: "myfont";
    src: url("fonts/awesome-font.woff") format('woff');
}

@font-face {
    font-family: "myfont";
    src: url("fonts/awesome-font-bold.woff") format('woff');
    font-weight: bold;
}

@font-face {
    font-family: "myfont";
    src: url("fonts/awesome-font-boldoblique.woff") format('woff');
    font-weight: bold;
    font-style: italic;
}

@font-face {
    font-family: "myfont";
    src: url("fonts/awesome-font-oblique.woff") format('woff');
    font-style: italic;
}

After having that definitions, you can just write, for example,

In HTML code:

<div class="mydiv">
    <b>this will be written with awesome-font-bold.woff</b>
    <br/>
    <b><i>this will be written with awesome-font-boldoblique.woff</i></b>
    <br/>
    <i>this will be written with awesome-font-oblique.woff</i>
    <br/>
    this will be written with awesome-font.woff
</div>

In CSS code:

.mydiv {
    font-family: myfont
}

The good tool for generation woff files, which can be included in CSS stylesheets is located here. Not all woff files work correctly under latest Firefox versions, and this generator produces 'correct' fonts.

To add to the already selected "Best Answer" (and others that are just as good like Suragch's), String.replace() is constrained by replacing characters that are sequential (thus taking CharSequence). However, String.replaceAll() is not constrained by replacing sequential characters only. You could replace non-sequential characters as well as long as your regular expression is constructed in such a way.

Also (most importantly and painfully obvious), replace() can only replace literal values; whereas replaceAll can replace 'like' sequences (not necessarily identical).

You can get first element via index selector:

$('div.second div:eq(0)')

Code: http://jsfiddle.net/RX46D/

You can write this in a more compact way:

var now = new Date();
now.setTime(now.getTime() + 1 * 3600 * 1000);
document.cookie = "name=value; expires=" + now.toUTCString() + "; path=/";

And for someone like me, who wasted an hour trying to figure out why the cookie with expiration is not set up (but without expiration can be set up) in Chrome, here is in answer:

For some strange reason Chrome team decided to ignore cookies from local pages. So if you do this on localhost, you will not be able to see your cookie in Chrome. So either upload it on the server or use another browser.

public boolean compareMap(Map<String, String> map1, Map<String, String> map2) {

    if (map1 == null || map2 == null)
        return false;

    for (String ch1 : map1.keySet()) {
        if (!map1.get(ch1).equalsIgnoreCase(map2.get(ch1)))
            return false;

    }
    for (String ch2 : map2.keySet()) {
        if (!map2.get(ch2).equalsIgnoreCase(map1.get(ch2)))
            return false;

    }

    return true;
}

If you're using the memory you've allocated, then you're not doing anything wrong. It becomes a problem when you write functions (other than main) that allocate memory without freeing it, and without making it available to the rest of your program. Then your program continues running with that memory allocated to it, but no way of using it. Your program and other running programs are deprived of that memory.

Edit: It's not 100% accurate to say that other running programs are deprived of that memory. The operating system can always let them use it at the expense of swapping your program out to virtual memory (</handwaving>). The point is, though, that if your program frees memory that it isn't using then a virtual memory swap is less likely to be necessary.

A simplier option is to just capture the digits and replace them.

const name = 'preceding_text_0_following_text';_x000D_
const matcher = /(\d+)/;_x000D_
_x000D_
// Replace with whatever you would like_x000D_
const newName = name.replace(matcher, 'NEW_STUFF');_x000D_
console.log("Full replace", newName);_x000D_
_x000D_
// Perform work on the match and replace using a function_x000D_
// In this case increment it using an arrow function_x000D_
const incrementedName = name.replace(matcher, (match) => ++match);_x000D_
console.log("Increment", incrementedName);

The Python dateutil library is designed for this (and more). It will automatically convert this to a datetime object for you and raise a ValueError if it can't.

As an example:

>>> from dateutil.parser import parse
>>> parse("2003-09-25")
datetime.datetime(2003, 9, 25, 0, 0)

This raises a ValueError if the date is not formatted correctly:

>>> parse("2003-09-251")
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Users/jacinda/envs/dod-backend-dev/lib/python2.7/site-packages/dateutil/parser.py", line 720, in parse
    return DEFAULTPARSER.parse(timestr, **kwargs)
  File "/Users/jacinda/envs/dod-backend-dev/lib/python2.7/site-packages/dateutil/parser.py", line 317, in parse
    ret = default.replace(**repl)
ValueError: day is out of range for month

dateutil is also extremely useful if you start needing to parse other formats in the future, as it can handle most known formats intelligently and allows you to modify your specification: dateutil parsing examples.

It also handles timezones if you need that.

Update based on comments: parse also accepts the keyword argument dayfirst which controls whether the day or month is expected to come first if a date is ambiguous. This defaults to False. E.g.

>>> parse('11/12/2001')
>>> datetime.datetime(2001, 11, 12, 0, 0) # Nov 12
>>> parse('11/12/2001', dayfirst=True)
>>> datetime.datetime(2001, 12, 11, 0, 0) # Dec 11

An absolute object inside a relative object is relative to its parent, the problem here is that you need a static width for the container #slideshowWrapper , and the rest of the solution is like the other users says

body {
    text-align: center;
}

#slideshowWrapper {
    margin-top: 50px;
    text-align:center;
    width: 500px;
}

ul#slideshow {
    list-style: none;
    position: relative;
    margin: auto;
}

ul#slideshow li {
    position: relative;
    left: 50%;
}

ul#slideshow li img {
    border: 1px solid #ccc;
    padding: 4px;
    height: 450px;
}

Here's a good mnemonic. Apply uses Arrays and Always takes one or two Arguments. When you use Call you have to Count the number of arguments.

Deep copy literally performs a deep copy. It means, that if your class has some fields that are references, their values will be copied, not references themselves. If, for example you have two instances of a class, A & B with fields of reference type, and perform a deep copy, changing a value of that field in A won't affect a value in B. And vise-versa. Things are different with shallow copy, because only references are copied, therefore, changing this field in a copied object would affect the original object.

What type of a copy does a copy constructor does?

It is implementation - dependent. This means that there are no strict rules about that, you can implement it like a deep copy or shallow copy, however as far as i know it is a common practice to implement a deep copy in a copy constructor. A default copy constructor performs a shallow copy though.

In this case you can use display:inline or inline-block.

Example:

img.likeordisklike {display:inline;vertical-align:middle;  }_x000D_
h4.liketext { color:#F00; display:inline;vertical-align:top;padding-left:10px; }

<img class='likeordislike' src='design/like.png'/><h4 class='liketext'>$likes</h4>_x000D_
<img class='likeordislike' src='design/dislike.png'/><h4 class='liketext'>$dislikes</h4>

Don't use float:left because again need to write one more clear line and its old method also..

The man page has very detailed descriptions of all of the various options (the status bar is highly configurable). Your best bet is to read through man tmux and pay particular attention to those options that begin with status-.

So, for example, status-bg red would set the background colour of the bar.

The three components of the bar, the left and right sections and the window-list in the middle, can all be configured to suit your preferences. status-left and status-right, in addition to having their own variables (like #S to list the session name) can also call custom scripts to display, for example, system information like load average or battery time.

The option to rename windows or panes based on what is currently running in them is automatic-rename. You can set, or disable it globally with:

setw -g automatic-rename [on | off]

The most straightforward way to become comfortable with building your own status bar is to start with a vanilla one and then add changes incrementally, reloading the config as you go.¹

You might also want to have a look around on github or bitbucket for other people's conf files to provide some inspiration. You can see mine here².

¹ You can automate this by including this line in your .tmux.conf:

bind R source-file ~/.tmux.conf \; display-message "Config reloaded..."

You can then test your new functionality with Ctrlb,Shiftr. tmux will print a helpful error message—including a line number of the offending snippet—if you misconfigure an option.

² Note: I call a different status bar depending on whether I am in X or the console - I find this quite useful.

Another option is to use showtext package which supports more types of fonts (TrueType, OpenType, Type 1, web fonts, etc.) and more graphics devices, and avoids using external software such as Ghostscript.

font_paths()    
#> [1] "C:\\Windows\\Fonts"

# List available font files in the search path

#>   [1] "AcadEref.ttf"

Edit: another workaround to use showtext in RStudio. Run the following code at the beginning of the R session (source)

trace(grDevices::png, exit = quote({
    showtext::showtext_begin()
}), print = FALSE)

Edit 2: Starting from version 0.9, showtext can work well with the RStudio graphics device (RStudioGD). Simply call showtext_auto() in the RStudio session and then the plots will be displayed correctly.

Also ensure that "client tools" are selected in the install options. However if SQL Managment Studio 2008 exists then it is likely that you installed the express edition.

This line will unconditionally restart the running program from scratch:

You can take a look at the bytecode whenever you want to understand how java operators work. Here if you compile:

int x = 0;
x += 0.1;

the bytecode will be accessible with jdk command javap -c [*.class]:(you can refer to Java bytecode instruction listings for more explanation about bytecode)

0: iconst_0 //  load the int value 0 onto the stack
1: istore_1 //  store int value into variable 1 (x)
2: iload_1 // load an int value from local variable 1 (x)
3: i2d // convert an int into a double (cast x to double)
4: ldc2_w        #2                  // double 0.1d -> push a constant value (0.1) from a constant pool onto the stack
7: dadd //  add two doubles (pops two doubles from stack, adds them, and pushes the answer onto stack)
8: d2i // convert a double to an int (pops a value from stack, casts it to int and pushes it onto stack)
9: istore_1 // store int value into variable 1 (x)

Now it is clear that java compiler promotes x to double and then adds it with 0.1.
Finally it casts the answer to integer .
There is one interesting fact I found out that when you write:

byte b = 10;
b += 0.1;

compiler casts b to double, adds it with 0.1, casts the result which is double to integer, and finally casts it to byte and that is because there is no instruction to cast double to byte directly.
You can check the bytecode if you doubt :)

This is official recommendation for upgrading Tensorflow.

To get TensorFlow 1.5, you can use the standard pip installation (or pip3 if you use python3)

In the case you are on something else then windows and your boss is forcing you to use azure devops, and you don't want to use SSH, and you want to use to plain old way, do the following.

You have to enable 'Alternate credentials' (I know it's annoying) or you need to create an access token. Creating an access token in this case is more like a temporary random password. If you use the windows tooling it is done for you.

Any way, go to Security in the profile context menu in the right upper corner.

Then if your boss/manager/dude that has the admin rights is favoring you the 'Alternate credentials' are enabled. Otherwise accept your fate and generate a 'Personal access token'.

This one is quite simple and does not require a delegate as you say.

(CA761232-ED42-11CE-BACD-00AA0057B223)

Update 1

@NonStatic makes the point in the comments that the above regex will match false positives which have a wrong closing delimiter.

This can be avoided by regex conditionals which are broadly supported.

Conditionals are supported by the JGsoft engine, Perl, PCRE, Python, and the .NET framework. Ruby supports them starting with version 2.0. Languages such as Delphi, PHP, and R that have regex features based on PCRE also support conditionals. (source http://www.regular-expressions.info/conditional.html)

The regex that follows Will match

{123}
(123)
123

And will not match

{123)
(123}
{123
(123
123}
123)

Regex:

^({)?(\()?\d+(?(1)})(?(2)\))$

The solutions is simplified to match only numbers to show in a more clear way what is required if needed.

Unfortunately, this is currently not possible.

The GitHub Markdown documentation has no mention of 'color', 'css', 'html', or 'style'.

While some Markdown processors (e.g. the one used in Ghost) allow for HTML, such as <span style="color:orange;">Word up</span>, GitHub's discards any HTML.

If it's imperative that you use color in your readme, your README.md could simply refer users to a README.html. The trade-off for this, of course, is accessibility.

            path: str.substring(0, nOffset),
            name: str.substring(nOffset > 0 ? nOffset + 1 : nOffset, eOffset),
            extension: str.substring(eOffset > 0 ? eOffset + 1 : eOffset, str.length)};
}

// Testing the function
var testcases = [
    "C:\\blabla\\blaeobuaeu\\testcase1.jpeg",
    "/tmp/blabla/testcase2.png",
    "testcase3.htm",
    "C:\\Testcase4", "/dir.with.dots/fileWithoutDots",
    "/dir.with.dots/another.dir/"
];
for(var i=0;i<testcases.length;i++)
{
    var file = pathToFile(testcases[i]);
    document.write("- " + (file.isDirectory ? "Directory" : "File") + " with name '" + file.name + "' has extension: '" + file.extension + "' is in directory: '" + file.path + "'<br />");
}
</script>
</body>
</html>

Will output the following:

• File with name 'testcase1' has extension: 'jpeg' is in directory: 'C:\blabla\blaeobuaeu'
• File with name 'testcase2' has extension: 'png' is in directory: '/tmp/blabla'
• File with name 'testcase3' has extension: 'htm' is in directory: ''
• Directory with name 'Testcase4' has extension: '' is in directory: 'C:'
• Directory with name 'fileWithoutDots' has extension: '' is in directory: '/dir.with.dots'
• Directory with name '' has extension: '' is in directory: '/dir.with.dots/another.dir'

With && nOffset+1 === str.length added to isDirectory:

• File with name 'testcase1' has extension: 'jpeg' is in directory: 'C:\blabla\blaeobuaeu'
• File with name 'testcase2' has extension: 'png' is in directory: '/tmp/blabla'
• File with name 'testcase3' has extension: 'htm' is in directory: ''
• Directory with name 'Testcase4' has extension: '' is in directory: 'C:'
• Directory with name 'fileWithoutDots' has extension: '' is in directory: '/dir.with.dots'
• Directory with name '' has extension: '' is in directory: '/dir.with.dots/another.dir'

Given the testcases you can see this function works quite robustly compared to the other proposed methods here.

Note for newbies about the \\: \ is an escape character, for example \n means a newline and \t a tab. To make it possible to write \n, you must actually type \\n.

xcopy "$(ProjectDir)Views\Home\Index.cshtml" "$(SolutionDir)MEFMVCPOC\Views\Home"

and if you want to copy entire folders:

xcopy /E /Y "$(ProjectDir)Views" "$(SolutionDir)MEFMVCPOC\Views"

Update: here's the working version

xcopy "$(ProjectDir)Views\ModuleAHome\Index.cshtml" "$(SolutionDir)MEFMVCPOC\Views\ModuleAHome\" /Y /I

Here are some commonly used switches with xcopy:

• /I - treat as a directory if copying multiple files.
• /Q - Do not display the files being copied.
• /S - Copy subdirectories unless empty.
• /E - Copy empty subdirectories.
• /Y - Do not prompt for overwrite of existing files.
• /R - Overwrite read-only files.

You can try with Angular-Tree-DnD sample with Angular-Ui-Tree, but i edited, compatibility with table, grid, list.

• Able Drag & Drop
• Extended function directive for list (next, prev, getChildren,...)
• Filter data.
• OrderBy (ver)

Try this

select * from sys.all_columns c join sys.objects o on c.object_id=o.object_id where o.name = 'TABLENAME' and c.name like '%COLUMN NAME%'

There is a ToObject method now.

var obj = jsonObject["date_joined"];
var result = obj.ToObject<DateTime>();

It also works with any complex type, and obey to JsonPropertyAttribute rules

var result = obj.ToObject<MyClass>();

public class MyClass 
{ 
    [JsonProperty("date_field")]
    public DateTime MyDate {get;set;}
}

The Least Popular Answer

1. A deprecated tag is not necessarily a bad tag;
2. There are tags that deal with presentation logic, center is one of them;
3. A center tag is not the same as a div with text-align:center;
4. The fact that you have another way to do something doesn't make it invalid.

Let me explain because there are notorious downvoters here who will think I'm defending oldschool HTML4 or something. No I'm not. But the debate around center is simply a trend war, there is no real reason to ditch a tag that serves a valid purpose well.

So let's see the major arguments against it.

• "It describes presentation, not semantics!"
  No. It describes a logical arrangement - and yes, it has a default appearance, just as other tags like <p> or <ul> do. But the point is the enclosed part's relation to its surroundings. Center says "this is something we separate by visually different positioning".

• "It's not valid"
  Yes it is. It's just deprecated, as in, could be removed later. For 15+ years now. And it's not going anywhere, apparently. There are major sites (including google.com) that use this tag because it's very readable and to the point - and those are the same reasons we like HTML5 tags for.

• "It's not supported in HTML5"
  It's one of the most widely supported tags, actually. MDN says "its use is discouraged since it could be removed at any time" - good point, but that day may never come, to quote a classic. Center was already deprecated in like 2004 or so - it's still here and still useful.

• "It's oldschool"
  Shoelaces are oldschool too. New methods don't invalidate the old. You want to feel progressive and modern: fine. But don't make it the law.

• "It's stupid / awkward / lame / tells a story about you"
  None of these. It's like a hammer: one tool for a specific job. There are other tools for the same job and other jobs for the same tool; but it was created to solve a certain problem and that problem is still around so we might as well just use a dedicated solution.

• "You shouldn't do this, because, CSS"
  Centering can absolutely be achieved by CSS but that's just one way, not the only one, let alone the only appropriate one. Anything that's supported, working and readable should be ok to use. Also, the same argument happened before flexboxes and CSS grids, which is funny because back then there was no CSS way to achieve what center did. No, text-align:center is not the same. No, margin:auto is not the same. Anyone who argued against center tags before flexbox simply didn't know enough about CSS.

TL;DR:

The only reason not to use <center> is because people will hate you.

Use socat for this:

For example:

socat PTY,link=/dev/ttyS10 PTY,link=/dev/ttyS11

I found it in /usr/local/nginx/logs/*.

This code basically reads a JSON array object and convert each row into an option in the spinner that is passed as a parameter:

public ArrayAdapter<String> getArrayAdapterFromArrayListForSpinner(ArrayList<JSONObject> aArrayList, String aField)
{
    ArrayAdapter<String> aArrayAdapter = new ArrayAdapter<String>(context, android.R.layout.simple_spinner_item);
    aArrayAdapter.setDropDownViewResource(R.layout.multiline_spinner_dropdown_item); //android.R.layout.simple_spinner_dropdown_item
    try {
        for (int i = 0; i < aArrayList.size(); i++)
        {
            aArrayAdapter.add(aArrayList.get(i).getString(aField)); 
        }
    } catch (JSONException e) {
        e.printStackTrace();
        ShowMessage("Error while reading the JSON list");
    }
    return aArrayAdapter;       
}

I have found the answer to this, and it is annoyingly/frustratingly simple! Basically the reply to addresses needed to be added before the from address as such:

$mail->addReplyTo('[email protected]', 'Reply to name');
$mail->SetFrom('[email protected]', 'Mailbox name');

Looking at the phpmailer code in more detail this is the offending line:

public function SetFrom($address, $name = '',$auto=1) {
   $address = trim($address);
   $name = trim(preg_replace('/[\r\n]+/', '', $name)); //Strip breaks and trim
   if (!self::ValidateAddress($address)) {
     $this->SetError($this->Lang('invalid_address').': '. $address);
     if ($this->exceptions) {
       throw new phpmailerException($this->Lang('invalid_address').': '.$address);
     }
     echo $this->Lang('invalid_address').': '.$address;
     return false;
   }
   $this->From = $address;
   $this->FromName = $name;
   if ($auto) {
      if (empty($this->ReplyTo)) {
         $this->AddAnAddress('ReplyTo', $address, $name);
      }
      if (empty($this->Sender)) {
         $this->Sender = $address;
      }
   }
   return true;
}

Specifically this line:

if (empty($this->ReplyTo)) {
   $this->AddAnAddress('ReplyTo', $address, $name);
}

Thanks for your help everyone!

Simply use list property count\

i = ['apple','red','apple','red','red','pear']
d = {x:i.count(x) for x in i}
print d

output :

{'pear': 1, 'apple': 2, 'red': 3}

Look at how the current Object Results are created. Here is the BadRequestObjectResult. Just an extension of the ObjectResult with a value and StatusCode.

https://github.com/aspnet/Mvc/blob/master/src/Microsoft.AspNetCore.Mvc.Core/BadRequestObjectResult.cs

I created a TimeoutExceptionObjectResult just the same way for 408.

/// <summary>
/// An <see cref="ObjectResult"/> that when executed will produce a Request Timeout (408) response.
/// </summary>
[DefaultStatusCode(DefaultStatusCode)]
public class TimeoutExceptionObjectResult : ObjectResult
{
    private const int DefaultStatusCode = StatusCodes.Status408RequestTimeout;

    /// <summary>
    /// Creates a new <see cref="TimeoutExceptionObjectResult"/> instance.
    /// </summary>
    /// <param name="error">Contains the errors to be returned to the client.</param>
    public TimeoutExceptionObjectResult(object error)
        : base(error)
    {
        StatusCode = DefaultStatusCode;
    }
}

Client:

if (ex is TimeoutException)
{
    return new TimeoutExceptionObjectResult("The request timed out.");
}

In JavaScript you can use template literals:

let value = 100;
console.log(`The size is ${ value }`);

It isn't the most obvious workflow. You first have to click "Load preferences from a custom folder or URL". Select the folder you want them saved in; I keep an appsync folder in Dropbox for these sorts of things. Once you have selected the folder, you can click "Save settings to Folder". On a new machine / fresh install of your OS, you can now load these settings from the folder. At first I was sure that loading preferences would wipe out my previous settings, but it didn't.

If it's not related to missing using directives stated by other users, this will also happen if there is another problem with your query.

Take a look on VS compiler error list : For example, if the "Value" variable in your query doesn't exist, you will have the "lambda to string" error, and a few errors after another one more related to the unknown/erroneous field.

In your case it could be :

objContentLine = (from q in db.qryContents
                  where q.LineID == Value
                  orderby q.RowID descending
                  select q).FirstOrDefault();

Errors:

Error 241 Cannot convert lambda expression to type 'string' because it is not a delegate type

Error 242 Delegate 'System.Func<..>' does not take 1 arguments

Error 243 The name 'Value' does not exist in the current context

Fix the "Value" variable error and the other errors will also disappear.

None of the other answers worked in my case, most likely because the JSON array contained special characters. What fixed it for me:

Javascript (added encodeURIComponent)

var JSONstr = encodeURIComponent(JSON.stringify(fullInfoArray));
document.getElementById('JSONfullInfoArray').value = JSONstr;

PHP (unchanged from the question)

$data = json_decode($_POST["JSONfullInfoArray"]);
var_dump($data);

echo($_POST["JSONfullInfoArray"]);

Both echo and var_dump have been verified to work fine on a sample of more than 2000 user-entered datasets that included a URL field and a long text field, and that were returning NULL on var_dump for a subset that included URLs with the characters ?&#.

If you are using VS Code, you can rename the .ts, .html, .css/.scss, .spec.ts files and the IDE will take care of the imports for you. Therefore there will be no complaints from the files that import files from your component (such as app.module.ts). However, you will still have to rename the component name everywhere it is being used.

For visualization and summary of PyTorch models, tensorboardX can also can be utilized.

One or more of your .cpp files is not being linked in, or some non-inline functions in some class are not defined. In particular, takeaway::textualGame()'s implementation can't be found. Note that you've defined a textualGame() at toplevel, but this is distinct from a takeaway::textualGame() implementation - probably you just forgot the takeaway:: there.

What the error means is that the linker can't find the "vtable" for a class - every class with virtual functions has a "vtable" data structure associated with it. In GCC, this vtable is generated in the same .cpp file as the first listed non-inline member of the class; if there's no non-inline members, it will be generated wherever you instantiate the class, I believe. So you're probably failing to link the .cpp file with that first-listed non-inline member, or never defining that member in the first place.

You can use encoding like ASCII to get a character per byte by using the System.Text.Encoding class.

or try this

  System.Text.ASCIIEncoding.Unicode.GetByteCount(string);
  System.Text.ASCIIEncoding.ASCII.GetByteCount(string);

For your problem, an Exists filter would probably perform the fastest.

    SqlConnectionStringBuilder builder = new SqlConnectionStringBuilder();
        builder.DataSource = <sql server name>;
        builder.UserID = <user id>; //User id used to login into SQL
        builder.Password = <password>; //password used to login into SQL
        builder.InitialCatalog = <database name>; //Name of Database

        DataTable orderTable = new DataTable();

        //<sp name> stored procedute name which you want to exceute
        using (var con = new SqlConnection(builder.ConnectionString))
        using (SqlCommand cmd = new SqlCommand(<sp name>, con)) 
        using (var da = new SqlDataAdapter(cmd))
        {
            cmd.CommandType = System.Data.CommandType.StoredProcedure;
            //Data adapter(da) fills the data retuned from stored procedure 
           //into orderTable
            da.Fill(orderTable);
        }

This is all generally covered by Section 23.3.2 of SystemVerilog IEEE Std 1800-2012.

The simplest way is to instantiate in the main section of top, creating a named instance and wiring the ports up in order:

module top(
   input        clk,
   input        rst_n,
   input        enable,
   input  [9:0] data_rx_1,
   input  [9:0] data_rx_2,
   output [9:0] data_tx_2
);

subcomponent subcomponent_instance_name (
  clk, rst_n, data_rx_1, data_tx ); 

endmodule

This is described in Section 23.3.2.1 of SystemVerilog IEEE Std 1800-2012.

This has a few draw backs especially regarding the port order of the subcomponent code. simple refactoring here can break connectivity or change behaviour. for example if some one else fixs a bug and reorders the ports for some reason, switching the clk and reset order. There will be no connectivity issue from your compiler but will not work as intended.

module subcomponent(
  input        rst_n,       
  input        clk,
  ...

It is therefore recommended to connect using named ports, this also helps tracing connectivity of wires in the code.

module top(
   input        clk,
   input        rst_n,
   input        enable,
   input  [9:0] data_rx_1,
   input  [9:0] data_rx_2,
   output [9:0] data_tx_2
);

subcomponent subcomponent_instance_name (
  .clk(clk), .rst_n(rst_n), .data_rx(data_rx_1), .data_tx(data_tx) ); 

endmodule

This is described in Section 23.3.2.2 of SystemVerilog IEEE Std 1800-2012.

Giving each port its own line and indenting correctly adds to the readability and code quality.

subcomponent subcomponent_instance_name (
  .clk      ( clk       ), // input
  .rst_n    ( rst_n     ), // input
  .data_rx  ( data_rx_1 ), // input  [9:0]
  .data_tx  ( data_tx   )  // output [9:0]
);

So far all the connections that have been made have reused inputs and output to the sub module and no connectivity wires have been created. What happens if we are to take outputs from one component to another:

clk_gen( 
  .clk      ( clk_sub   ), // output
  .en       ( enable    )  // input

subcomponent subcomponent_instance_name (
  .clk      ( clk_sub   ), // input
  .rst_n    ( rst_n     ), // input 
  .data_rx  ( data_rx_1 ), // input  [9:0]
  .data_tx  ( data_tx   )  // output [9:0]
);

This nominally works as a wire for clk_sub is automatically created, there is a danger to relying on this. it will only ever create a 1 bit wire by default. An example where this is a problem would be for the data:

Note that the instance name for the second component has been changed

subcomponent subcomponent_instance_name (
  .clk      ( clk_sub   ), // input
  .rst_n    ( rst_n     ), // input 
  .data_rx  ( data_rx_1 ), // input  [9:0]
  .data_tx  ( data_temp )  // output [9:0]
);
subcomponent subcomponent_instance_name2 (
  .clk      ( clk_sub   ), // input
  .rst_n    ( rst_n     ), // input 
  .data_rx  ( data_temp ), // input  [9:0]
  .data_tx  ( data_tx   )  // output [9:0]
);

The issue with the above code is that data_temp is only 1 bit wide, there would be a compile warning about port width mismatch. The connectivity wire needs to be created and a width specified. I would recommend that all connectivity wires be explicitly written out.

wire [9:0] data_temp
subcomponent subcomponent_instance_name (
  .clk      ( clk_sub   ), // input
  .rst_n    ( rst_n     ), // input 
  .data_rx  ( data_rx_1 ), // input  [9:0]
  .data_tx  ( data_temp )  // output [9:0]
);
subcomponent subcomponent_instance_name2 (
  .clk      ( clk_sub   ), // input
  .rst_n    ( rst_n     ), // input 
  .data_rx  ( data_temp ), // input  [9:0]
  .data_tx  ( data_tx   )  // output [9:0]
);

Moving to SystemVerilog there are a few tricks available that save typing a handful of characters. I believe that they hinder the code readability and can make it harder to find bugs.

Use .port with no brackets to connect to a wire/reg of the same name. This can look neat especially with lots of clk and resets but at some levels you may generate different clocks or resets or you actually do not want to connect to the signal of the same name but a modified one and this can lead to wiring bugs that are not obvious to the eye.

module top(
   input        clk,
   input        rst_n,
   input        enable,
   input  [9:0] data_rx_1,
   input  [9:0] data_rx_2,
   output [9:0] data_tx_2
);

subcomponent subcomponent_instance_name (
  .clk,                    // input **Auto connect**
  .rst_n,                  // input **Auto connect**
  .data_rx  ( data_rx_1 ), // input  [9:0]
  .data_tx  ( data_tx   )  // output [9:0]
);

endmodule

This is described in Section 23.3.2.3 of SystemVerilog IEEE Std 1800-2012.

Another trick that I think is even worse than the one above is .* which connects unmentioned ports to signals of the same wire. I consider this to be quite dangerous in production code. It is not obvious when new ports have been added and are missing or that they might accidentally get connected if the new port name had a counter part in the instancing level, they get auto connected and no warning would be generated.

subcomponent subcomponent_instance_name (
  .*,                      // **Auto connect**
  .data_rx  ( data_rx_1 ), // input  [9:0]
  .data_tx  ( data_tx   )  // output [9:0]
);

This is described in Section 23.3.2.4 of SystemVerilog IEEE Std 1800-2012.

A Kotlin Extension to observe on the global layout and perform a given task when height is ready dynamically.

mx.iloc[0].idxmax()

This one line of code will give you how to find the maximum value from a row in dataframe, here mx is the dataframe and iloc[0] indicates the 0th index.

According to my understanding to your question, as an example: you had a style at the beginning in style sheet (ex. background-color: red), then using java script you changed it to another style (ex. background-color: green), now you want to reset the style to its original value in style sheet (background-color: red) without mentioning or even knowing its value (ex. element.style.backgroundColor = 'red')...!

If I'm correct, I have a good solution for you which is using another class name for the element:

steps:

1. set the default styles in style sheet as usual according to your desire.
2. define a new class name in style sheet and add the new style you want.
3. when you want to trigger between styles, add the new class name to the element or remove it.

if you want to edit or set a new style, get the element by the new class name and edit the style as desired.

I hope this helps. Regards!

Including the jQuery Library

That is jQuery code. You'll first need to make sure the jQuery library is loaded. If you don't host the library file yourself, you can hotlink one from the jQuery CDN:

<script src="//code.jquery.com/jquery-1.11.3.min.js"></script>

You can do this within the <head> section, but it's fine as long as it's loaded before your jQuery code.

Further reading:

• Why should I use Google's CDN for jQuery?
• Microsoft CDN for jQuery or Google CDN?

Placing Your Code in the Page

Place your code inside <script> tags. It can be inserted anywhere within either <head> or <body>. If you place it before the <input> and <tr> tags (as referenced in your code), you have to use $(document).ready() to make sure those elements are present before the code is run:

$(document).ready(function() {
    // put your jQuery code here.
});

If you want your page content to be loaded as soon as possible, you might want to place it as close as the </body> close tag as possible. But another common practice is to place all JavaScript code in the <head> section. This is your choice, based on your coding style and needs.

Suggestion: Instead of embedding JS/jQuery code directly into an HTML page, consider placing the code in a separate .js file. This will allow you to reuse the same code on other pages:

<script src="/path/to/your/code.js"></script>

If there is no hard requirement on the length of the truncated string, one can use this to truncate and prevent cutting the last word as well:

$text = "Knowledge is a natural right of every human being of which no one
has the right to deprive him or her under any pretext, except in a case where a
person does something which deprives him or her of that right. It is mere
stupidity to leave its benefits to certain individuals and teams who monopolize
these while the masses provide the facilities and pay the expenses for the
establishment of public sports.";

// we don't want new lines in our preview
$text_only_spaces = preg_replace('/\s+/', ' ', $text);

// truncates the text
$text_truncated = mb_substr($text_only_spaces, 0, mb_strpos($text_only_spaces, " ", 50));

// prevents last word truncation
$preview = trim(mb_substr($text_truncated, 0, mb_strrpos($text_truncated, " ")));

In this case, $preview will be "Knowledge is a natural right of every human being".

While reading the TCP UDP debate I noticed a logical flaw. A TCP packet loss causing a one minute delay that's converted into a one minute buffer cant be correlated to UDP dropping a full minute while experiencing the same loss. A more fair comparison is as follows.

TCP experiences a packet loss. The video is stopped while TCP resend's packets in an attempt to stream mathematically perfect packets. Video is delayed for one minute and picks up where it left off after missing packet makes its destination. We all wait but we know we wont miss a single pixel.

UDP experiences a packet loss. For a second during the video stream a corner of the screen gets a little blurry. No one notices and the show goes on without looking for the lost packets.

Anything that streams gains the most benefits from UDP. The packet loss causing a one minute delay to TCP would not cause a one minute delay to UDP. Considering that most systems use multiple resolution streams making things go blocky when starving for packets, makes even more sense to use UDP.

UDP FTW when streaming.

Please read and strongly consider my advice in the comments of your post. That being said, if you still have a good reason to do this, check out this list of crypto modules for Node. It has modules for dealing with both sha1 and base64.

The difference between RMI and RPC is that:

• RMI as the name indicates Remote Method Invoking: it invokes a method or an object. And
• RPC it invokes a function.

See help(Sys.sleep).

For example, from ?Sys.sleep

testit <- function(x)
{
    p1 <- proc.time()
    Sys.sleep(x)
    proc.time() - p1 # The cpu usage should be negligible
}
testit(3.7)

Yielding

> testit(3.7)
   user  system elapsed

I found a super simple explanation about class << self , Eigenclass and different type of methods.

In Ruby, there are three types of methods that can be applied to a class:

1. Instance methods
2. Singleton methods
3. Class methods

Instance methods and class methods are almost similar to their homonymous in other programming languages.

class Foo  
  def an_instance_method  
    puts "I am an instance method"  
  end  
  def self.a_class_method  
    puts "I am a class method"  
  end  
end

foo = Foo.new

def foo.a_singleton_method
  puts "I am a singletone method"
end

Another way of accessing an Eigenclass(which includes singleton methods) is with the following syntax (class <<):

foo = Foo.new

class << foo
  def a_singleton_method
    puts "I am a singleton method"
  end
end

now you can define a singleton method for self which is the class Foo itself in this context:

class Foo
  class << self
    def a_singleton_and_class_method
      puts "I am a singleton method for self and a class method for Foo"
    end
  end
end

Add this code to your page:

<script type="text/javascript">
$(document).ready(function() {
   $("input[type='submit']").click(function(){
      $(this).css('background-color','red');
    });
});
</script>

In addition to Ctrl+Shift+F (Cmd+Option+F on Mac) as suggested in this answer, you can right click on the top tree node in the sources tab and select "Search in All Files":

This work-around worked for me: http://connect.microsoft.com/PowerShell/feedback/details/419466/new-webserviceproxy-needs-force-parameter-to-ignore-ssl-errors

Basically, in your PowerShell script:

add-type @"
    using System.Net;
    using System.Security.Cryptography.X509Certificates;
    public class TrustAllCertsPolicy : ICertificatePolicy {
        public bool CheckValidationResult(
            ServicePoint srvPoint, X509Certificate certificate,
            WebRequest request, int certificateProblem) {
            return true;
        }
    }
"@
[System.Net.ServicePointManager]::CertificatePolicy = New-Object TrustAllCertsPolicy

$result = Invoke-WebRequest -Uri "https://IpAddress/resource"

You could use the @Consumes annotation to get the full body:

import javax.ws.rs.Consumes;
import javax.ws.rs.POST;
import javax.ws.rs.Path;
import javax.ws.rs.core.MediaType;
import javax.xml.transform.Transformer;
import javax.xml.transform.TransformerConfigurationException;
import javax.xml.transform.TransformerException;
import javax.xml.transform.TransformerFactory;
import javax.xml.transform.dom.DOMSource;
import javax.xml.transform.stream.StreamResult;
import org.w3c.dom.Document;

@Path("doc")
public class BodyResource
{
  @POST
  @Consumes(MediaType.APPLICATION_XML)
  public void post(Document doc) throws TransformerConfigurationException, TransformerException
  {
    Transformer tf = TransformerFactory.newInstance().newTransformer();
    tf.transform(new DOMSource(doc), new StreamResult(System.out));
  }
}

Note: Don't forget the "Content-Type: application/xml" header by the request.

I used similar code to @MethodMan but I had to keep track of the data the serial port was sending and look for a terminating character to know when the serial port was done sending data.

private string buffer { get; set; }
private SerialPort _port { get; set; }

public Port() 
{
    _port = new SerialPort();
    _port.DataReceived += new SerialDataReceivedEventHandler(dataReceived);
    buffer = string.Empty;
}

private void dataReceived(object sender, SerialDataReceivedEventArgs e)
{    
    buffer += _port.ReadExisting();

    //test for termination character in buffer
    if (buffer.Contains("\r\n"))
    {
        //run code on data received from serial port
    }
}

Here's how i finally created the ~/.android/debug.keystore file.

First some background. I got a new travel laptop. Installed Android Studio. Cloned my android project from git hub. The project would not run. Finally figured out that the debug.keystore was not created ... and i could not figure out how to get Android Studio to create it.

Finally, i created a new blank project ... and that created the debug.keystore!

Hope this helps other who have this problem.

The preferred method is actually:

@System.Web.Configuration.WebConfigurationManager.AppSettings["myKey"]

It also doesn't need a reference to the ConfigurationManager assembly, it's already in System.Web.

maybe map, but since you don't want to make a list, you can write your own...

def call_for_all(f, seq):
    for i in seq:
        f(i)

then you can do:

call_for_all(lamda x: x.start(), all)
call_for_all(lamda x: x.stop(), all)

by the way, all is a built in function, don't overwrite it ;-)

This probably isn't what you wanted me to say, but this is a good use of AOP. Whip an proxy interceptor around your method, and do the timing in there.

The what, why and how of AOP is rather beyond the scope of this answer, sadly, but that's how I'd likely do it.

Edit: Here's a link to Spring AOP to get you started, if you're keen. This is the most accessible implementation of AOP that Iive come across for java.

Also, given everyone else's very simple suggestions, I should add that AOP is for when you don't want stuff like timing to invade your code. But in many cases, that sort of simple and easy approach is fine.

I found this plugin to be doing what I was expecting: gulp-using

Simple usage example: Search all files in project with .jsx extension

gulp.task('reactify', function(){
        gulp.src(['../**/*.jsx']) 
            .pipe(using({}));
        ....
    });

Output:

[gulp] Using gulpfile /app/build/gulpfile.js
[gulp] Starting 'reactify'...
[gulp] Finished 'reactify' after 2.92 ms
[gulp] Using file /app/staging/web/content/view/logon.jsx
[gulp] Using file /app/staging/web/content/view/components/rauth.jsx

I've never been happy with the way anybody explains this.

The key to understanding closures is to understand what JS would be like without closures.

Without closures, this would throw an error

function outerFunc(){
    var outerVar = 'an outerFunc var';
    return function(){
        alert(outerVar);
    }
}

outerFunc()(); //returns inner function and fires it

Once outerFunc has returned in an imaginary closure-disabled version of JavaScript, the reference to outerVar would be garbage collected and gone leaving nothing there for the inner func to reference.

Closures are essentially the special rules that kick in and make it possible for those vars to exist when an inner function references an outer function's variables. With closures the vars referenced are maintained even after the outer function is done or 'closed' if that helps you remember the point.

Even with closures, the life cycle of local vars in a function with no inner funcs that reference its locals works the same as it would in a closure-less version. When the function is finished, the locals get garbage collected.

Once you have a reference in an inner func to an outer var, however it's like a doorjamb gets put in the way of garbage collection for those referenced vars.

A perhaps more accurate way to look at closures, is that the inner function basically uses the inner scope as its own scope foudnation.

But the context referenced is in fact, persistent, not like a snapshot. Repeatedly firing a returned inner function that keeps incrementing and logging an outer function's local var will keep alerting higher values.

function outerFunc(){
    var incrementMe = 0;
    return function(){ incrementMe++; console.log(incrementMe); }
}
var inc = outerFunc();
inc(); //logs 1
inc(); //logs 2

Something like this:

  public static void main(String[] args) {
   String N = "ABCD";
   char[] array = N.toCharArray();

   // and as you can see:
    System.out.println(array[0]);
    System.out.println(array[1]);
    System.out.println(array[2]);
  }

It allows servlets to have multiple servlet mappings:

<servlet>
    <servlet-name>Servlet1</servlet-name>
    <servlet-path>foo.Servlet</servlet-path>
</servlet>
<servlet-mapping>
    <servlet-name>Servlet1</servlet-name>
    <url-pattern>/enroll</url-pattern>
</servlet-mapping>
<servlet-mapping>
    <servlet-name>Servlet1</servlet-name>
    <url-pattern>/pay</url-pattern>
</servlet-mapping>
<servlet-mapping>
    <servlet-name>Servlet1</servlet-name>
    <url-pattern>/bill</url-pattern>
</servlet-mapping>

It allows filters to be mapped on the particular servlet:

<filter-mapping>
    <filter-name>Filter1</filter-name>
    <servlet-name>Servlet1</servlet-name>
</filter-mapping>

Your proposal would support neither of them. Note that the web.xml is read and parsed only once during application's startup, not on every HTTP request as you seem to think.

Since Servlet 3.0, there's the @WebServlet annotation which minimizes this boilerplate:

@WebServlet("/enroll")
public class Servlet1 extends HttpServlet {

install PIL using the command "sudo apt-get install python-imaging" and run the following program. It will print RGB values of the image. If the image is large redirect the output to a file using '>' later open the file to see RGB values

import PIL
import Image
FILENAME='fn.gif' #image can be in gif jpeg or png format 
im=Image.open(FILENAME).convert('RGB')
pix=im.load()
w=im.size[0]
h=im.size[1]
for i in range(w):
  for j in range(h):
    print pix[i,j]

• START_STICKY: It will restart the service in case if it terminated and the Intent data which is passed to the onStartCommand() method is NULL. This is suitable for the service which are not executing commands but running independently and waiting for the job.
• START_NOT_STICKY: It will not restart the service and it is useful for the services which will run periodically. The service will restart only when there are a pending startService() calls. It’s the best option to avoid running a service in case if it is not necessary.
• START_REDELIVER_INTENT: It’s same as STAR_STICKY and it recreates the service, call onStartCommand() with last intent that was delivered to the service.

Actual for EntityFrameworkCore 3.1.3:

some solution in OnModelCreating:

var fixDecimalDatas = new List<Tuple<Type, Type, string>>();
foreach (var entityType in builder.Model.GetEntityTypes())
{
    foreach (var property in entityType.GetProperties())
    {
        if (Type.GetTypeCode(property.ClrType) == TypeCode.Decimal)
        {
            fixDecimalDatas.Add(new Tuple<Type, Type, string>(entityType.ClrType, property.ClrType, property.GetColumnName()));
        }
    }
}

foreach (var item in fixDecimalDatas)
{
    builder.Entity(item.Item1).Property(item.Item2, item.Item3).HasColumnType("decimal(18,4)");
}

//custom decimal nullable:
builder.Entity<SomePerfectEntity>().Property(x => x.IsBeautiful).HasColumnType("decimal(18,4)");

yes you can do this on windows too, here's the code below, using the conio.h library

#include <iostream> //basic input/output
#include <conio.h>  //provides non standard getch() function
using namespace std;

int main()
{  
  cout << "Password: ";  
  string pass;
  while(true)
  {
             char ch = getch();    

             if(ch=='\r'){  //when a carriage return is found [enter] key
             cout << endl << "Your password is: " << pass <<endl; 
             break;
             }

             pass+=ch;             
             cout << "*";
             }
  getch();
  return 0;
}

An alternative is to use StreamReader.

public void FunctionName(HttpPostedFileBase file)
{
    string result = new StreamReader(file.InputStream).ReadToEnd();
}

    private String temp = "mahesh.hiren.darshan";

    String s_temp[] = temp.split("[.]");

  Log.e("1", ""+s_temp[0]);

I had the same issue, and spent quite a bit of time trying to track down the solution. I had Anonymous Authentication set up at two different levels with two different users. Make sure that you're not overwriting your set up at a lower level.

Java

public static String getApplicationName(Context context) {
    return context.getApplicationInfo().loadLabel(context.getPackageManager()).toString();
}

Kotlin (as extension)

fun Context.getAppName(): String = applicationInfo.loadLabel(packageManager).toString()

Maybe you should try removing "new" keyword and see if works. Because last time I got this error when I tried creating Typeface something like this:

Typeface typeface = new Typeface().create("Arial",Typeface.BOLD);

For comparing jsons I recommend using JSONCompare: https://github.com/fslev/json-compare

// Compare by regex
String expected = "{\"a\":\".*me.*\"}";
String actual = "{\"a\":\"some text\"}";
JSONCompare.assertEquals(expected, actual);  // True

// Check expected array has no extra elements
String expected = "[1,\"test\",4,\"!.*\"]";
String actual = "[4,1,\"test\"]";
JSONCompare.assertEquals(expected, actual);  // True

// Check expected array has no numbers
String expected = "[\"\\\\\\d+\"]";
String actual = "[\"text\",\"test\"]";
JSONCompare.assertEquals(expected, actual);  // True

// Check expected array has no numbers
String expected = "[\"\\\\\\d+\"]";
String actual = "[2018]";
JSONCompare.assertNotEquals(expected, actual);  // True

Are you perhaps looking for:

int Difference = (a-b).Hours;

Indeed, there is no defined standard. To support that information, have a look at wikipedia, in the Query String chapter. There is the following comment:

While there is no definitive standard, most web frameworks allow multiple values to be associated with a single field.[3][4]

Furthermore, when you take a look at the RFC 3986, in section 3.4 Query, there is no definition for parameters with multiple values.

Most applications use the first option you have shown: http://server/action?id=a&id=b. To support that information, take a look at this Stackoverflow link, and this MSDN link regarding ASP.NET applications, which use the same standard for parameters with multiple values.

However, since you are developing the APIs, I suggest you to do what is the easiest for you, since the caller of the API will not have much trouble creating the query string.

If you want to learn about win32, WTL http://wtl.sourceforge.net/ is the pretty lightweight equivalent to MFC, but you have to love template to use it.

If you want something simple MFC is already integrated with VS, also it has a large base of extra code and workarounds of know bugs in the net already.

Also Qt is really great framework it have a nice set of tools, dialog editor, themes, and a lot of other stuff, plus your application will be ready to be cross platform, although it will require some time to get accustomed.

You also have Gtk, wxWindow, and you will have no problems if you have already used it on linux.

Use Pattern package in Android to match the input validation for email and phone

The following Link has explained complete details about how to back sql server 2008 database using c#

Sql Database backup can be done using many way. You can either use Sql Commands like in the other answer or have create your own class to backup data.

But these are different mode of backup.

1. Full Database Backup
2. Differential Database Backup
3. Transaction Log Backup
4. Backup with Compression

But the disadvantage with this method is that it needs your sql management studio to be installed on your client system.

$.getJSON() is pretty handy for sending an AJAX request and getting back JSON data as a response. Alas, the jQuery documentation lacks a sister function that should be named $.postJSON(). Why not just use $.getJSON() and be done with it? Well, perhaps you want to send a large amount of data or, in my case, IE7 just doesn’t want to work properly with a GET request.

It is true, there is currently no $.postJSON() method, but you can accomplish the same thing by specifying a fourth parameter (type) in the $.post() function:

My code looked like this:

$.post('script.php', data, function(response) {
  // Do something with the request
}, 'json');

You want to do something like the following:

• Open the old file for reading
• Open a new (temporary) file for writing
• Iterate over the lines in the old file (probably using a BufferedReader)
  • For each line, check if it matches what you are supposed to remove
  • If it matches, do nothing
  • If it doesn't match, write it to the temporary file
• When done, close both files
• Delete the old file
• Rename the temporary file to the name of the original file

(I won't write the actual code, since this looks like homework, but feel free to post other questions on specific bits that you have trouble with)

This is probably system-dependent, but this is the simplest way I've found.

if [ -e /var/run/nginx.pid ]; then echo "nginx is running"; fi

That's the best solution for scripting.

This happens because your upstream takes too much to answer the request and NGINX thinks the upstream already failed in processing the request, so it responds with an error. Just include and increase proxy_read_timeout in location config block. Same thing happened to me and I used 1 hour timeout for an internal app at work:

proxy_read_timeout 3600;

With this, NGINX will wait for an hour (3600s) for its upstream to return something.

To avoid multiple formdata sends:

Don't forget to unbind submit event, before the form submited again, User can call sumbit function more than one time, maybe he forgot something, or was a validation error.

 $("#idForm").unbind().submit( function(e) {
  ....

You may have to first update all the records that are null to the default value then use the alter table statement.

Update dbo.TableName
Set
Created="01/01/2000"
where Created is NULL

Click in the grid so it has focus.

Ctrl+End

This will force the rest of the records back into the grid.

In React 16.13, you can set it directly inside the render function:

import React from 'react';
import ReactDOM from 'react-dom';

class App extends React.Component {
    render() {
        document.title = 'wow'
        return <p>Hello</p>
    }
}

ReactDOM.render(
    <App />,
    document.getElementById('root')
)

For function component:

function App() {
    document.title = 'wow'
    return <p>Hello</p>
}

I found 'Python Script' plugin for Notepad++ more useful since with the plugin, I could write simple macros in the form of python and It has also got very good documentation and sample macros written in python as well. If you are quite comfortable with python, then I think 'Python Script' will provide justice. For more information, refer : http://npppythonscript.sourceforge.net/

@skaffman nailed it down. They live each in its own context. However, I wouldn't consider using scriptlets as the solution. You'd like to avoid them. If all you want is to concatenate strings in EL and you discovered that the + operator fails for strings in EL (which is correct), then just do:

<c:out value="abc${test}" />

Or if abc is to obtained from another scoped variable named ${resp}, then do:

<c:out value="${resp}${test}" />

Sometimes gradlew clean or Invalidate Cache and Restart does not help, because these methods do not clean Android Studio specific files by themselves.

In this case, close AS and remove .idea directory and .iml file in a root project where settings.gradle file exists. This will make AS rebuild from the fresh ground.

My issue was that I called nltk.download('all') as the root user, but the process that eventually used nltk was another user who didn't have access to /root/nltk_data where the content was downloaded.

So I simply recursively copied everything from the download location to one of the paths where NLTK was looking to find it like this:

cp -R /root/nltk_data/ /home/ubuntu/nltk_data

There are ready-made shortcuts (syntactic sugar) to the function wrapper @CMS answered with. (Below assuming that the context you want is this.tip.)

ECMAScript 2015 (all common browsers and smartphones, Node.js 5.0.0+)

For virtually all javascript development (in 2020) you can use fat arrow functions, which are part of the ECMAScript 2015 (Harmony/ES6/ES2015) specification.

An arrow function expression (also known as fat arrow function) has a shorter syntax compared to function expressions and lexically binds the this value [...].

(param1, param2, ...rest) => { statements }

In your case, try this:

if (this.options.destroyOnHide) {
    setTimeout(() => { this.tip.destroy(); }, 1000);
}

ECMAScript 5 (older browsers and smartphones, Node.js) and Prototype.js

If you target browser compatible with ECMA-262, 5th edition (ECMAScript 5) or Node.js, which (in 2020) means all common browsers as well as older browsers, you could use Function.prototype.bind. You can optionally pass any function arguments to create partial functions.

fun.bind(thisArg[, arg1[, arg2[, ...]]])

Again, in your case, try this:

if (this.options.destroyOnHide) {
    setTimeout(this.tip.destroy.bind(this.tip), 1000);
}

The same functionality has also been implemented in Prototype (any other libraries?).

Function.prototype.bind can be implemented like this if you want custom backwards compatibility (but please observe the notes).

jQuery

If you are already using jQuery 1.4+, there's a ready-made function for explicitly setting the this context of a function.

jQuery.proxy(): Takes a function and returns a new one that will always have a particular context.

$.proxy(function, context[, additionalArguments])

In your case, try this:

if (this.options.destroyOnHide) {
    setTimeout($.proxy(this.tip.destroy, this.tip), 1000);
}

Underscore.js, lodash

It's available in Underscore.js, as well as lodash, as _.bind(...)^1,2

bind Bind a function to an object, meaning that whenever the function is called, the value of this will be the object. Optionally, bind arguments to the function to pre-fill them, also known as partial application.

_.bind(function, object, [*arguments])

In your case, try this:

if (this.options.destroyOnHide) {
    setTimeout(_.bind(this.tip.destroy, this.tip), 1000);
}

bind jquery underscore.js ecmascript-5 prototypejs node.js

Use the above code by placing this html file and pics(take care in namings, beacause I have given the above code with my pic names) in same folder you will get...

You can solve this problem using this code:

if(!empty($_GET['variable from which you get'])) 
{
$_SESSION['something']= $_GET['variable from which you get'];
}

So you get the variable from a GET form, you will store in the $_SESSION['whatever'] variable just once when $_GET['variable from which you get']is set and if it is empty $_SESSION['something'] will store the old parameter

The message is fairly self-explanatory; your working directory should not be the NumPy source directory when you invoke Python; NumPy should be installed and your working directory should be anything but the directory where it lives.

What you want is this constructor: std::string ( const string& str, size_t pos, size_t n = npos ), passing pos as 0. Your const char* c-style string will get implicitly cast to const string for the first parameter.

const char *c_style = "012abd";
std::string cpp_style = new std::string(c_style, 0, 10);

It seems to me there is value in considering some rewrites to your SQL code before attempting to translate it.

Personally, I'd write such a query as a union (although I'd avoid nulls entirely!):

SELECT f.value
  FROM period as p JOIN facts AS f ON p.id = f.periodid
WHERE p.companyid = 100
      AND f.otherid = 17
UNION
SELECT NULL AS value
  FROM period as p
WHERE p.companyid = 100
      AND NOT EXISTS ( 
                      SELECT * 
                        FROM facts AS f
                       WHERE p.id = f.periodid
                             AND f.otherid = 17
                     );

So I guess I agree with the spirit of @MAbraham1's answer (though their code seems to be unrelated to the question).

However, it seems the query is expressly designed to produce a single column result comprising duplicate rows -- indeed duplicate nulls! It's hard not to come to the conclusion that this approach is flawed.

I'm seeing the same thing. A quick google found this question and a bug on the chromium forums. It seems that the --user-data-dir flag is now required. Edit to add user-data-dir guide

Subclass the ArrayAdapter and override the method getView() to return your own view that contains the contents that you want to display.

Swift 4 parses JSON much more elegantly. Just adopt the codable protocol for your structure as per this simplified example:

struct Business: Codable {
    let id: Int
    let name: String
}

To parse the JSON array, you tell the decoder what the objects of the data array are

let parsedData = decoder.decode([Business].self, from: data)

Here's a full working example:

import Foundation

struct Business: Codable {
    let id: Int
    let name: String
}

// Generating the example JSON data: 
let originalObjects = [Business(id: 0, name: "A"), Business(id: 1, name: "B")]
let encoder = JSONEncoder()
let data = try! encoder.encode(originalObjects)

// Parsing the data: 
let decoder = JSONDecoder()
let parsedData = try! decoder.decode([Business].self, from: data)

For more background, check out this excellent guide.

Below is the node.js file to call this html file.

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

var server = http.createServer(function(req, resp){
  // Print the name of the file for which request is made.
  console.log("Request for demo file received.");
  fs.readFile("Documents/nodejs/demo.html",function(error, data){
    if (error) {
      resp.writeHead(404);
      resp.write('Contents you are looking for-not found');
      resp.end();
    }  else {
      resp.writeHead(200, {
        'Content-Type': 'text/html'
      });
      resp.write(data.toString());
      resp.end();
    }
  });
});

server.listen(8081, '127.0.0.1');

console.log('Server running at http://127.0.0.1:8081/');

Intiate the above nodejs file in command prompt and the message "Server running at http://127.0.0.1:8081/" is displayed.Now in your browser type "http://127.0.0.1:8081/demo.html".

First, create the new branch you would like to set as your default, for example:

$>git branch main

Next, push that branch to the origin:

$>git push origin main

Now when you login to your GitHub account, you can go to your repository and choose Settings>Default Branch and choose "main."

Then, if you so choose, you can delete the master branch:

$>git push origin :master

I was getting this same issue, and none of the other answers here helped my particular case.

It turned out to be because my Android Studio project was defaulting to use JDK 8.

Changing this, in the project settings, to point at a JDK 7 installation fixed this for me.

You can use the WebFont module, which greatly simplifies the process.

render(){
  webfont.load({
     custom: {
       families: ['MyFont'],
       urls: ['/fonts/MyFont.woff']
     }
  });
  return (
    <div style={your style} >
      your text!
    </div>
  );
}

An idea could be to use the optgroup. In my case found it better than the disabled approach. It's less confusing for the user than seeing the disabled option I think.

<select id="q1" v-model="selected" v-on:change="setCPost1(selected)">
  <option value="0"></option>
  <template
    v-for="(child, idx) in getLevel1"
    v-bind:value="child.id"      
  >

  <optgroup v-bind:value="child.id" :key="idx"
  :label="child.label"
  v-if="child.label_line_two"
  >
  </optgroup>

  <option v-bind:value="child.id" :key="idx"  v-if="!child.label_line_two"
  >
  {{ child.label }}  
  </option>

  <option v-bind:value="child.id" :key="idx" v-if="child.label_line_two"
  style="font-style:italic">
  {{ child.label_line_two }}
  </option>


  </template>
</select>

An external component sounds cool like Vue Select, but I wanted to stick with the native html select at the moment.

Helvetica Neue is a paid font, so you shouldn't @font-face it, as you'd be freely distributing a copyrighted font. It's included in Mac systems but not in windows/linux ones, so yes, plenty of your users wont have it installed. Anyway, you can use 'Arial Narrow' as a windows substitute, which is it's windows equivalent.

Question is a little vague.

list_of_lines = multiple_lines.split("\n")
for line in list_of_lines:
    list_of_items_in_line = line.split(",")
    first_int = int(list_of_items_in_line[0])

etc.

In your PHP code you have set the incorrect port, this is what the code should be

<?php

$dbhost = 'localhost';
$dbuser = 'root';
$dbpass = '';
$db     = 'test_db13';

The port in your code is set to 3360 when it should be 3306, however as this is the default port, you don't need to specify.

For making a CORS request one must add headers to the request along with the same he needs to check of mode_header is enabled in Apache.

For enabling headers in Ubuntu:

sudo a2enmod headers

For php server to accept request from different origin use:

Header set Access-Control-Allow-Origin *
Header set Access-Control-Allow-Methods "GET, POST, PUT, DELETE"
Header always set Access-Control-Allow-Headers "x-requested-with, Content-Type, origin, authorization, accept, client-security-token"

In my case I found that simply clearing the animation on the view before setting the visibility to GONE works.

dp2.clearAnimation();
dp2.setVisibility(View.GONE);

I had a similar issue where I toggle between two views, one of which must always start off as GONE - But when I displayed the views again, it was displaying over the first view even if setVisibility(GONE) was called. Clearing the animation before setting the view to GONE worked.

I looked at most the solutions posted, but came across a different one that I prefer. It's simple, doesn't use threads, and works for what I want it to.

http://weblogs.asp.net/kennykerr/archive/2004/11/26/where-is-form-s-loaded-event.aspx

I added to the solution in the article and moved the code into a base class that all my forms inherit from. Now I just call one function: ShowWaitForm() during the frm_load() event of any form that needs a wait dialogue box while the form is loading. Here's the code:

public class MyFormBase : System.Windows.Forms.Form
{
    private MyWaitForm _waitForm;

    protected void ShowWaitForm(string message)
    {
        // don't display more than one wait form at a time
        if (_waitForm != null && !_waitForm.IsDisposed) 
        {
            return;
        }

        _waitForm = new MyWaitForm();
        _waitForm.SetMessage(message); // "Loading data. Please wait..."
        _waitForm.TopMost = true;
        _waitForm.StartPosition = FormStartPosition.CenterScreen;
        _waitForm.Show();
        _waitForm.Refresh();

        // force the wait window to display for at least 700ms so it doesn't just flash on the screen
        System.Threading.Thread.Sleep(700);         
        Application.Idle += OnLoaded;
    }

    private void OnLoaded(object sender, EventArgs e)
    {
        Application.Idle -= OnLoaded;
        _waitForm.Close();
    }
}

MyWaitForm is the name of a form you create to look like a wait dialogue. I added a SetMessage() function to customize the text on the wait form.

If you want to cleanup docker images and containers

CAUTION: this will flush everything

stop all containers

docker stop $(docker ps -a -q)

remove all containers

docker rm $(docker ps -a -q)

remove all images

docker rmi -f $(docker images -a -q)

If you compile with optimizations enabled, then many variables will be removed; for example:

SomeType value = GetValue();
DoSomething(value);

here the local variable value would typically get removed, keeping the value on the stack instead - a bit like as if you had written:

DoSomething(GetValue());

Also, if a return value isn't used at all, then it will be dropped via "pop" (rather than stored in a local via "stloc", and again; the local will not exist).

Because of this, in such a build the debugger can't get the current value of value because it doesn't exist - it only exists for the brief instant between GetValue() and DoSomething(...).

So; if you want to debug... don't use a release build! or at least, disable optimizations while you debug.

sudo yum remove python-beautifulsoup

OR

sudo easy_install -m BeautifulSoup

can remove old version 3

I stuck with the same issue. I have found easiest solution which I like to share.

1) Create new branch with your changes.

git checkout -b mybranch

2) (Optional) Push new branch code on remote server.

git push origin mybranch

3) Checkout back to master branch.

git checkout master

4) Reset master branch code with remote server and remove local commit.

git reset --hard origin/master

you can rename constraint objects using sp_rename (as described in this answer)

for example:

EXEC sp_rename N'schema.MyIOldConstraint', N'MyNewConstraint'

I had this error because of my stupidity. In the manifest.xml I have wrongly declared two Activity as Launcher. Make sure you have only one activity as Launcher.

    <activity android:name=".MainActivity">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

   <activity android:name=".WelcomeActivity">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>
    </activity>

I'm writing an answer to increase visibility to the actual syntax that solves the problem. Unfortunately, what someone might see as trivial can become a very significant headache to someone looking for a simple answer to a reasonable question.

Put the following into the file "Makefile".

MY_VAR := $(shell python -c 'import sys; print int(sys.version_info >= (2,5))')

all:
    @echo MY_VAR IS $(MY_VAR)

The behavior you would like to see is the following (assuming you have recent python installed).

make
MY_VAR IS 1

If you copy and paste the above text into the Makefile, will you get this? Probably not. You will probably get an error like what is reported here:

makefile:4: *** missing separator. Stop

Why: Because although I personally used a genuine tab, Stack Overflow (attempting to be helpful) converts my tab into a number of spaces. You, frustrated internet citizen, now copy this, thinking that you now have the same text that I used. The make command, now reads the spaces and finds that the "all" command is incorrectly formatted. So copy the above text, paste it, and then convert the whitespace before "@echo" to a tab, and this example should, at last, hopefully, work for you.

Its better to always encode spaces as %20, not as "+".

It was RFC-1866 (HTML 2.0 specification), which specified that space characters should be encoded as "+" in "application/x-www-form-urlencoded" content-type key-value pairs. (see paragraph 8.2.1. subparagraph 1.). This way of encoding form data is also given in later HTML specifications, look for relevant paragraphs about application/x-www-form-urlencoded.

Here is an example of such a string in URL where RFC-1866 allows encoding spaces as pluses: "http://example.com/over/there?name=foo+bar". So, only after "?", spaces can be replaced by pluses, according to RFC-1866. In other cases, spaces should be encoded to %20. But since it's hard to determine the context, it's the best practice to never encode spaces as "+".

I would recommend to percent-encode all character except "unreserved" defined in RFC-3986, p.2.3

unreserved = ALPHA / DIGIT / "-" / "." / "_" / "~"

They differ in their types. They're all zero, but NULL is a void *, nil is an id, and Nil is a Class pointer.

The sizzle selector engine (what powers JQuery) is perfectly geared up for this:

var elements = $('input[type=text]');

Or

var elements = $('input:text');

"A requires a peer of B but none was installed". Consider it as "A requires one of B's peers but that peer was not installed and we're not telling you which of B's peers you need."

The automatic installation of peer dependencies was explicitly removed with npm 3.

NPM Blog

Release notes of v3

So you cannot install peer dependencies automatically with npm 3 and upwards.

Updated Solution:

Use following for each peer dependency to install that and remove the error

npm install --save-dev xxxxx

Deprecated Solution:

1. You can use npm-install-peers to find and install required peer dependencies.

   npm install -g npm-install-peers

   npm-install-peers

2. If you are getting this error after updating any package's version then remove node_modules directory and reinstall packages by npm install or npm cache clean and npm install.

Ok, finally found the solution.

Probably due to lack of experience with ReactJS and web development...

    var Task = React.createClass({
    render: function() {
      var percentage = this.props.children + '%';
      ....
        <div className="ui-progressbar-value ui-widget-header ui-corner-left" style={{width : percentage}}/>
      ...

I created the percentage variable outside in the render function.

You can also do this -

var handle = Activator.CreateInstance("AssemblyName", 
                "Full name of the class including the namespace and class name");
var obj = handle.Unwrap();

If you run pub build --mode=debug the build directory contains the application without symlinks. The Dart code should be retained when --mode=debug is used.

Here is some discussion going on about this topic too Dart and it's place in Rails Assets Pipeline

I have come up with a solution that is relatively accurate at evaluating when the angular initialisation is complete.

The directive is:

.directive('initialisation',['$rootScope',function($rootScope) {
            return {
                restrict: 'A',
                link: function($scope) {
                    var to;
                    var listener = $scope.$watch(function() {
                        clearTimeout(to);
                        to = setTimeout(function () {
                            console.log('initialised');
                            listener();
                            $rootScope.$broadcast('initialised');
                        }, 50);
                    });
                }
            };
        }]);

That can then just be added as an attribute to the body element and then listened for using $scope.$on('initialised', fn)

It works by assuming that the application is initialised when there are no more $digest cycles. $watch is called every digest cycle and so a timer is started (setTimeout not $timeout so a new digest cycle is not triggered). If a digest cycle does not occur within the timeout then the application is assumed to have initialised.

It is obviously not as accurate as satchmoruns solution (as it is possible a digest cycle takes longer than the timeout) but my solution doesn't need you to keep track of the modules which makes it that much easier to manage (particularly for larger projects). Anyway, seems to be accurate enough for my requirements. Hope it helps.

'Create Excel

Set objExcel = Wscript.CreateObject("Excel.Application")

objExcel.visible = True

Set objWb = objExcel.Workbooks.Add

objWb.Saveas("D:\Example.xlsx")

objExcel.Quit

There are three parts:

1. Add a 'shebang' at the top of your script which tells how to execute your script
2. Give the script 'run' permissions.
3. Make the script in your PATH so you can run it from anywhere.

Adding a shebang

You need to add a shebang at the top of your script so the shell knows which interpreter to use when parsing your script. It is generally:

#!path/to/interpretter

To find the path to your python interpretter on your machine you can run the command:

which python

This will search your PATH to find the location of your python executable. It should come back with a absolute path which you can then use to form your shebang. Make sure your shebang is at the top of your python script:

#!/usr/bin/python

Run Permissions

You have to mark your script with run permissions so that your shell knows you want to actually execute it when you try to use it as a command. To do this you can run this command:

chmod +x myscript.py

Add the script to your path

The PATH environment variable is an ordered list of directories that your shell will search when looking for a command you are trying to run. So if you want your python script to be a command you can run from anywhere then it needs to be in your PATH. You can see the contents of your path running the command:

echo $PATH

This will print out a long line of text, where each directory is seperated by a semicolon. Whenever you are wondering where the actual location of an executable that you are running from your PATH, you can find it by running the command:

which <commandname>

Now you have two options: Add your script to a directory already in your PATH, or add a new directory to your PATH. I usually create a directory in my user home directory and then add it the PATH. To add things to your path you can run the command:

export PATH=/my/directory/with/pythonscript:$PATH

Now you should be able to run your python script as a command anywhere. BUT! if you close the shell window and open a new one, the new one won't remember the change you just made to your PATH. So if you want this change to be saved then you need to add that command at the bottom of your .bashrc or .bash_profile

Try this :

$('.close-button').on('click', function(){
  $('.element').removeClass('grown');
  $('.element').addClass('spot');
});

$('.element').on('click', function(){
  $(this).removeClass('spot');
  $(this).addClass('grown');
});

I hope I understood your question.
