I happened to encounter a similar kind of issue after setting up local internal JFrog Docker Private Registry on Amazon Linux.

THE followings I did to solve the issue:

Added "--insecure-registry xx.xx.xx.xx:8081" by modifying the OPTIONS variable in the /etc/sysconfig/docker file:

OPTIONS="--default-ulimit nofile=1024:40961 --insecure-registry hostname:8081"

Then restarted the docker.

I was then able to login to the local docker registry using:

docker login -u admin -p password hostname:8081

I think it depends on what OS you are using, Vista is much harder to attach to Services, because of the separation between sessions.

The two options I've used in the past are:

• Use GFlags (in the Debugging Tools for Windows) to setup a permanent debugger for a process. This exists in the "Image File Execution Options" registry key and is incredibly useful. I think you'll need to tweak the Service settings to enable "Interact with Desktop". I use this for all types of debugging, not just services.
• The other option, is to separate the code a bit, so that the service part is interchangable with a normal app startup. That way, you can use a simple command line flag, and launch as a process (rather than a Service), which makes it much easier to debug.

Hope this helps.

As a MAC address can be 6 or 20 bytes (infiniband, ...) the correct answer is:

^([0-9A-Fa-f]{2}:){5}(([0-9A-Fa-f]{2}:){14})?([0-9A-Fa-f]{2})$

you can replace : with [:-.]? if you want different separators or none.

It is supported as of Java 12. Check out JEP 354. No "range" possibilities here, but can be useful either.

switch (day) {
    case MONDAY, FRIDAY, SUNDAY -> System.out.println(6);//number of letters
    case TUESDAY                -> System.out.println(7);
    case THURSDAY, SATURDAY     -> System.out.println(8);
    case WEDNESDAY              -> System.out.println(9);
}

You should be able to implement that on ints too. Note through that your switch statement have to be exhaustive (using default keyword, or using all possible values in case statements).

The error as reported appears when the variables are null (or empty):

$ unset var3 var4; var5=$(($var4-$var3))
bash: -: syntax error: operand expected (error token is "-")

That could happen because the value given to bc was incorrect. That might well be that bc needs UPPERcase values. It needs BFCA3000, not bfca3000. That is easily fixed in bash, just use the ^^ expansion:

var3=bfca3000; var3=`echo "ibase=16; ${var1^^}" | bc`

That will change the script to this:

#!/bin/bash

var1="bfca3000"
var2="efca3250"

var3="$(echo "ibase=16; ${var1^^}" | bc)"
var4="$(echo "ibase=16; ${var2^^}" | bc)"

var5="$(($var4-$var3))"

echo "Diference $var5"

But there is no need to use bc [1], as bash could perform the translation and substraction directly:

#!/bin/bash

var1="bfca3000"
var2="efca3250"

var5="$(( 16#$var2 - 16#$var1 ))"

echo "Diference $var5"

[1]^{Note: I am assuming the values could be represented in 64 bit math, as the difference was calculated in bash in your original script. Bash is limited to integers less than ((2**63)-1) if compiled in 64 bits. That will be the only difference with bc which does not have such limit.}

A predicate in T is a delegate that takes in a T and returns a bool. List<T>.RemoveAll will remove all elements in a list where calling the predicate returns true. The easiest way to supply a simple predicate is usually a lambda expression, but you can also use anonymous methods or actual methods.

{
    List<Vehicle> vehicles;
    // Using a lambda
    vehicles.RemoveAll(vehicle => vehicle.EnquiryID == 123);
    // Using an equivalent anonymous method
    vehicles.RemoveAll(delegate(Vehicle vehicle)
    {
        return vehicle.EnquiryID == 123;
    });
    // Using an equivalent actual method
    vehicles.RemoveAll(VehiclePredicate);
}

private static bool VehiclePredicate(Vehicle vehicle)
{
    return vehicle.EnquiryID == 123;
}

it feels like it's stupid access the filesystem and get the contents for every subdirectory instead of getting everything at once.

Your feeling is wrong. That's how filesystems work. There is no faster way (except when you have to do this repeatedly or for different patterns, you can cache all the file paths in memory, but then you have to deal with cache invalidation i.e. what happens when files are added/removed/renamed while the app runs).

Go and buy the book titled "Java examples in a nutshell". In the book you will find most of practical examples.

To update a subset of fields, you can use update_fields:

survey.save(update_fields=["active"]) 

The update_fields argument was added in Django 1.5. In earlier versions, you could use the update() method instead:

Survey.objects.filter(pk=survey.pk).update(active=True)

Understand this has been solved, but the solution provided above might not work in all situation.

For my case,

<div style="height: 490px; position:relative; overflow:hidden">
    <div id="map-canvas"></div>
</div>

A replacement implement:

class A:

    def __init__(self):
        self.a = 123

    def kill(self):
        from itertools import chain
        for attr_name in chain(dir(self.__class__), dir(self)):
            if attr_name.startswith('__'):
                continue
            attr = getattr(self, attr_name)
            if callable(attr):
                setattr(self, attr_name, lambda *args, **kwargs: print('NoneType'))
            else:
                setattr(self, attr_name, None)
        a.__str__ = lambda: ''
        a.__repr__ = lambda: ''

a = A()
print(a.a)
a.kill()

print(a.a)
a.kill()

a = A()
print(a.a)

will outputs:

123
None
NoneType
123

-XX:PermSize specifies the initial size that will be allocated during startup of the JVM. If necessary, the JVM will allocate up to -XX:MaxPermSize.

I just used post and an if:

data = getDataObjectByForm(form);
var jqxhr = $.post(url, data, function(){}, 'json')
    .done(function (response) {

            var json = response;
        else
            var json = $.parseJSON(response);
        // console.log(response);
        // console.log(json);
        jsonToDom(json);
        if (json.reload != undefined && json.reload)
            location.reload();
        $("body").delay(1000).css("cursor", "default");
    })
    .fail(function (jqxhr, textStatus, error) {
        var err = textStatus + ", " + error;
        console.log("Request Failed: " + err);
        alert("Fehler!");

OR

you right in aspx.cs file like

SqlConnection conn = new SqlConnection("Data Source=12.16.1.25;Initial Catalog=Login;Persist Security Info=True;User ID=sa;Password=example.com");

While Markdown doesn't support color, if you don't need too many, you could always sacrifice some of the supported styles and redefine the related tag using CSS to make it color, and also remove the formatting, or not.

Example:

// resets
s { text-decoration:none; } //strike-through
em { font-style: normal; font-weight: bold; } //italic emphasis


// colors
s { color: green }
em { color: blue }

See also: How to restyle em tag to be bold instead of italic

Then in your markdown text

~~This is green~~
_this is blue_

Try this:

Dim text As String = ""
Dim files() As String = IO.Directory.GetFiles(sFolder)

For Each sFile As String In files
    text &= IO.File.ReadAllText(sFile)
Next

However this question is seeking to find the last row using VBA, I think it would be good to include an array formula for worksheet function as this gets visited frequently:

{=ADDRESS(MATCH(INDEX(D:D,MAX(IF(D:D<>"",ROW(D:D)-ROW(D1)+1)),1),D:D,0),COLUMN(D:D))}

You need to enter the formula without brackets and then hit Shift + Ctrl + Enter to make it an array formula.

This will give you address of last used cell in the column D.

My guess is, that the @Value can not cope with "complex" types. You can go with a prop class like this:

@Component
@ConfigurationProperties('ignore')
class IgnoreSettings {
    List<String> filenames
}

Please note: This code is Groovy - not Java - to keep the example short! See the comments for tips how to adopt.

See the complete example https://github.com/christoph-frick/so-springboot-yaml-string-list

if ($inputs['type'] == 'attach') {

The code is valid, but it expects the function parameter $inputs to be an array. The "Illegal string offset" warning when using $inputs['type'] means that the function is being passed a string instead of an array. (And then since a string offset is a number, 'type' is not suitable.)

So in theory the problem lies elsewhere, with the caller of the code not providing a correct parameter.

However, this warning message is new to PHP 5.4. Old versions didn't warn if this happened. They would silently convert 'type' to 0, then try to get character 0 (the first character) of the string. So if this code was supposed to work, that's because abusing a string like this didn't cause any complaints on PHP 5.3 and below. (A lot of old PHP code has experienced this problem after upgrading.)

You might want to debug why the function is being given a string by examining the calling code, and find out what value it has by doing a var_dump($inputs); in the function. But if you just want to shut the warning up to make it behave like PHP 5.3, change the line to:

if (is_array($inputs) && $inputs['type'] == 'attach') {

I use old good printf approach (an ancient technique which will work well in any time).

Look to magic %o:

console.log("this is %o, event is %o, host is %s", this, e, location.host);

%o dump clickable and deep-browsable, pretty-printed content of JS object. %s was shown just for a record.

And this:

console.log("%s", new Error().stack);

gives you Java-like stack trace to point of new Error() invocation (including path to file and line number!!).

Both %o and new Error().stack available in Chrome and Firefox.

With such powerful tools you make assumption whats going wrong in your JS, put debug output (don't forget wrap in if statement to reduce amount of data) and verify your assumption. Fix issue or make new assumption or put more debug output to bit problem.

Also for stack traces use:

console.trace();

as say Console

Happy hacking!

You could decompose the date into it's constituent parts and then concatenate them together like this:

JSONP is a great away to get around cross-domain scripting errors. You can consume a JSONP service purely with JS without having to implement a AJAX proxy on the server side.

You can use the b1t.co service to see how it works. This is a free JSONP service that alllows you to minify your URLs. Here is the url to use for the service:

http://b1t.co/Site/api/External/MakeUrlWithGet?callback=[resultsCallBack]&url=[escapedUrlToMinify]

For example the call, http://b1t.co/Site/api/External/MakeUrlWithGet?callback=whateverJavascriptName&url=google.com

would return

whateverJavascriptName({"success":true,"url":"http://google.com","shortUrl":"http://b1t.co/54"});

And thus when that get's loaded in your js as a src, it will automatically run whateverJavascriptName which you should implement as your callback function:

function minifyResultsCallBack(data)
{
    document.getElementById("results").innerHTML = JSON.stringify(data);
}

To actually make the JSONP call, you can do it about several ways (including using jQuery) but here is a pure JS example:

function minify(urlToMinify)
{
   url = escape(urlToMinify);
   var s = document.createElement('script');
   s.id = 'dynScript';
   s.type='text/javascript';
   s.src = "http://b1t.co/Site/api/External/MakeUrlWithGet?callback=resultsCallBack&url=" + url;
   document.getElementsByTagName('head')[0].appendChild(s);
}

A step by step example and a jsonp web service to practice on is available at: this post

Because & has a lesser priority than ==.

Your code is equivalent to a[0] & (1 == 0), and unless a[0] is a boolean this won't compile...

You need to:

(a[0] & 1) == 0

etc etc.

(yes, Java does hava a boolean & operator -- a non shortcut logical and)

This makes me wonder, when is it advisable to use the EntityManager.getReference() method instead of the EntityManager.find() method?

EntityManager.getReference() is really an error prone method and there is really very few cases where a client code needs to use it.
Personally, I never needed to use it.

EntityManager.getReference() and EntityManager.find() : no difference in terms of overhead

I disagree with the accepted answer and particularly :

If i call find method, JPA provider, behind the scenes, will call

SELECT NAME, AGE FROM PERSON WHERE PERSON_ID = ?

UPDATE PERSON SET AGE = ? WHERE PERSON_ID = ?

If i call getReference method, JPA provider, behind the scenes, will call

UPDATE PERSON SET AGE = ? WHERE PERSON_ID = ?

It is not the behavior that I get with Hibernate 5 and the javadoc of getReference() doesn't say such a thing :

Get an instance, whose state may be lazily fetched. If the requested instance does not exist in the database, the EntityNotFoundException is thrown when the instance state is first accessed. (The persistence provider runtime is permitted to throw the EntityNotFoundException when getReference is called.) The application should not expect that the instance state will be available upon detachment, unless it was accessed by the application while the entity manager was open.

EntityManager.getReference() spares a query to retrieve the entity in two cases :

1) if the entity is stored in the Persistence context, that is the first level cache.
And this behavior is not specific to EntityManager.getReference(), EntityManager.find() will also spare a query to retrieve the entity if the entity is stored in the Persistence context.

You can check the first point with any example.
You can also rely on the actual Hibernate implementation.
Indeed, EntityManager.getReference() relies on the createProxyIfNecessary() method of the org.hibernate.event.internal.DefaultLoadEventListener class to load the entity.
Here is its implementation :

private Object createProxyIfNecessary(
        final LoadEvent event,
        final EntityPersister persister,
        final EntityKey keyToLoad,
        final LoadEventListener.LoadType options,
        final PersistenceContext persistenceContext) {
    Object existing = persistenceContext.getEntity( keyToLoad );
    if ( existing != null ) {
        // return existing object or initialized proxy (unless deleted)
        if ( traceEnabled ) {
            LOG.trace( "Entity found in session cache" );
        }
        if ( options.isCheckDeleted() ) {
            EntityEntry entry = persistenceContext.getEntry( existing );
            Status status = entry.getStatus();
            if ( status == Status.DELETED || status == Status.GONE ) {
                return null;
            }
        }
        return existing;
    }
    if ( traceEnabled ) {
        LOG.trace( "Creating new proxy for entity" );
    }
    // return new uninitialized proxy
    Object proxy = persister.createProxy( event.getEntityId(), event.getSession() );
    persistenceContext.getBatchFetchQueue().addBatchLoadableEntityKey( keyToLoad );
    persistenceContext.addProxy( keyToLoad, proxy );
    return proxy;
}

The interesting part is :

Object existing = persistenceContext.getEntity( keyToLoad );

2) If we don't effectively manipulate the entity, echoing to the lazily fetched of the javadoc.
Indeed, to ensure the effective loading of the entity, invoking a method on it is required.
So the gain would be related to a scenario where we want to load a entity without having the need to use it ? In the frame of applications, this need is really uncommon and in addition the getReference() behavior is also very misleading if you read the next part.

Why favor EntityManager.find() over EntityManager.getReference()

In terms of overhead, getReference() is not better than find() as discussed in the previous point.
So why use the one or the other ?

Invoking getReference() may return a lazily fetched entity.
Here, the lazy fetching doesn't refer to relationships of the entity but the entity itself.
It means that if we invoke getReference() and then the Persistence context is closed, the entity may be never loaded and so the result is really unpredictable. For example if the proxy object is serialized, you could get a null reference as serialized result or if a method is invoked on the proxy object, an exception such as LazyInitializationException is thrown.

It means that the throw of EntityNotFoundException that is the main reason to use getReference() to handle an instance that does not exist in the database as an error situation may be never performed while the entity is not existing.

EntityManager.find() doesn't have the ambition of throwing EntityNotFoundException if the entity is not found. Its behavior is both simple and clear. You will never have surprise as it returns always a loaded entity or null (if the entity is not found) but never an entity under the shape of a proxy that may not be effectively loaded.
So EntityManager.find() should be favored in the very most of cases.

Since enums with Strings values differ from the ones that have number values it is better to filter nonNumbers from @user8363 solution.

Here is how you can get values from enum either strings, numbers of mixed:

    //Helper
    export const StringIsNotNumber = value => isNaN(Number(value)) === true;
    
    // Turn enum into array
    export function enumToArray(enumme) {
      return Object.keys(enumme)
       .filter(StringIsNotNumber)
       .map(key => enumme[key]);
    }

Might be cleaner to use PrintWriter and its method println.
Just make sure you close the writer when you're done

Tested on Ideone.

import json
array = '{"fruits": ["apple", "banana", "orange"]}'
data  = json.loads(array)
fruits_list = data['fruits']
print fruits_list

Your regular expression should be \btrue\b to get around the 'miscontrue' issue Casper brings up. The full solution would look like this:

string searchText = "7,true,NA,false:67,false,NA,false:5,false,NA,false:5,false,NA,false";
string regexPattern = @"\btrue\b";
int numberOfTrues = Regex.Matches(searchText, regexPattern).Count;

Make sure the System.Text.RegularExpressions namespace is included at the top of the file.

We can hide close button on form by setting this.ControlBox=false;

Note that this hides all of those sizing buttons. Not just the X. In some cases that may be fine.

This is an old post, but I ended up using Peter Lang's thoughts, and did a similar, but yet different approach. Here is what I did:

CREATE OR REPLACE FUNCTION multi_replace(
                        pString IN VARCHAR2
                        ,pReplacePattern IN VARCHAR2
) RETURN VARCHAR2 IS
    iCount  INTEGER;
    vResult VARCHAR2(1000);
    vRule   VARCHAR2(100);
    vOldStr VARCHAR2(50);
    vNewStr VARCHAR2(50);
BEGIN
    iCount := 0;
    vResult := pString;
    LOOP
        iCount := iCount + 1;

        -- Step # 1: Pick out the replacement rules
        vRule := REGEXP_SUBSTR(pReplacePattern, '[^/]+', 1, iCount);

        -- Step # 2: Pick out the old and new string from the rule
        vOldStr := REGEXP_SUBSTR(vRule, '[^=]+', 1, 1);
        vNewStr := REGEXP_SUBSTR(vRule, '[^=]+', 1, 2);

        -- Step # 3: Do the replacement
        vResult := REPLACE(vResult, vOldStr, vNewStr);

        EXIT WHEN vRule IS NULL;
    END LOOP;

    RETURN vResult;
END multi_replace;

Then I can use it like this:

SELECT  multi_replace(
                        'This is a test string with a #, a $ character, and finally a & character'
                        ,'#=%23/$=%24/&=%25'
        )
FROM dual

This makes it so that I can can any character/string with any character/string.

I just got the same error after I upgraded to 10.14 Mojave and had to reinstall command line tools (I don't use the full Xcode IDE and wanted command line tools a la carte).

My xcode-select -p path was right, per Basav's answer, so that wasn't the issue.

I also ran sudo softwareupdate --clear-catalog per Lambda W's answer and that reset to Apple Production, but did not make a difference.

What worked was User 92's answer to visit https://developer.apple.com/download/more/.

From there I was able to download a .dmg file that had a GUI installer wizard for command line tools :)

I installed that, then I restarted terminal and everything was back to normal.

Let’s make it simple:

++[[]][+[]]+[+[]] = "10"

var a = [[]][+[]];
var b = [+[]];

// so a == [] and b == [0]

++a;

// then a == 1 and b is still that array [0]
// when you sum the var a and an array, it will sum b as a string just like that:

1 + "0" = "10"

Answer Clarification - Android Studio supports JDK8

The following is an answer to the question "What version of Java does Android support?" which is different from "What version of Java can I use to run Android Studio?" which is I believe what was actually being asked. For those looking to answer the 2nd question, you might find Using Android Studio with Java 1.7 helpful.

Also: See http://developer.android.com/sdk/index.html#latest for Android Studio system requirements. JDK8 is actually a requirement for PC and linux (as of 5/14/16).

Java 8 update (3/19/14)

Because I'd assume this question will start popping up soon with the release yesterday: As of right now, there's no set date for when Android will support Java 8.

Here's a discussion over at /androiddev - http://www.reddit.com/r/androiddev/comments/22mh0r/does_android_have_any_plans_for_java_8/

If you really want lambda support, you can checkout Retrolambda - https://github.com/evant/gradle-retrolambda. I've never used it, but it seems fairly promising.

Another Update: Android added Java 7 support

Android now supports Java 7 (minus try-with-resource feature). You can read more about the Java 7 features here: https://stackoverflow.com/a/13550632/413254. If you're using gradle, you can add the following in your build.gradle:

android {
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_7
        targetCompatibility JavaVersion.VERSION_1_7
    }
}

Older response

I'm using Java 7 with Android Studio without any problems (OS X - 10.8.4). You need to make sure you drop the project language level down to 6.0 though. See the screenshot below.

What tehawtness said below makes sense, too. If they're suggesting JDK 6, it makes sense to just go with JDK 6. Either way will be fine.

Update: See this SO post -- https://stackoverflow.com/a/9567402/413254

In my case, i had copied a plugins folder into workspace from a collegue. Becaouse it was an unzipped folder, the structure was like 'pluginsfolder inside a plugins folder2 . so make sure that all the plugins are directly located under the toppest plugins folder at the workspace.

It's generally considered bad practice. The problem is that the constants are part of the public "interface" (for want of a better word) of the implementing class. This means that the implementing class is publishing all of these values to external classes even when they are only required internally. The constants proliferate throughout the code. An example is the SwingConstants interface in Swing, which is implemented by dozens of classes that all "re-export" all of its constants (even the ones that they don't use) as their own.

But don't just take my word for it, Josh Bloch also says it's bad:

The constant interface pattern is a poor use of interfaces. That a class uses some constants internally is an implementation detail. Implementing a constant interface causes this implementation detail to leak into the class's exported API. It is of no consequence to the users of a class that the class implements a constant interface. In fact, it may even confuse them. Worse, it represents a commitment: if in a future release the class is modified so that it no longer needs to use the constants, it still must implement the interface to ensure binary compatibility. If a nonfinal class implements a constant interface, all of its subclasses will have their namespaces polluted by the constants in the interface.

An enum may be a better approach. Or you could simply put the constants as public static fields in a class that cannot be instantiated. This allows another class to access them without polluting its own API.

Taken from here and it worked for me :

1.Go to IIS Manager.

2.Click on your app.

3.Go to "Handler Mappings".

4.In the feature list, double click on "WebDAV".

5.Click on "Request Restrictions".

6.In the tab "Verbs" select "All verbs" .

7.Press OK.

INSERT INTO prices (group, id, price)
  SELECT 7, articleId, 1.50 FROM article WHERE name LIKE 'ABC%'

$('#myinput').is(':checkbox')

this is the only work, to solve the issue to detect if checkbox checked or not. It returns true or false, I search it for hours and try everything, now its work to be clear I use EDG as browser and W2UI

Going back to Servlet days, web.xml can have only one <context-param>, so only one context object gets created when server loads an application and the data in that context is shared among all resources (Ex: Servlets and JSPs). It is same as having Database driver name in the context, which will not change. In similar way, when we declare contextConfigLocation param in <contex-param> Spring creates one Application Context object.

 <context-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>com.myApp.ApplicationContext</param-value>
 </context-param>

You can have multiple Servlets in an application. For example you might want to handle /secure/* requests in one way and /non-seucre/* in other way. For each of these Servlets you can have a context object, which is a WebApplicationContext.

<servlet>
    <servlet-name>SecureSpringDispatcher</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
        <param-name>contextClass</param-name>
        <param-value>com.myapp.secure.SecureContext</param-value>
    </init-param>
</servlet>
<servlet-mapping>
    <servlet-name>SecureSpringDispatcher</servlet-name>
    <url-pattern>/secure/*</url-pattern>
</servlet-mapping>
<servlet>
    <servlet-name>NonSecureSpringDispatcher</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
        <param-name>contextClass</param-name>
        <param-value>com.myapp.non-secure.NonSecureContext</param-value>
    </init-param>
</servlet>
<servlet-mapping>
    <servlet-name>NonSecureSpringDispatcher</servlet-name>
    <url-pattern>/non-secure/*</url-patten>
</servlet-mapping>

select convert(varchar(10), cast(fmdate as date), 101) from sery

Without cast I was not getting fmdate converted, so fmdate was a string.

Suppose you have a function:

def sinus2d(x, y):
    return np.sin(x) + np.sin(y)

and you want, for example, to see what it looks like in the range 0 to 2*pi. How would you do it? There np.meshgrid comes in:

xx, yy = np.meshgrid(np.linspace(0,2*np.pi,100), np.linspace(0,2*np.pi,100))
z = sinus2d(xx, yy) # Create the image on this grid

and such a plot would look like:

import matplotlib.pyplot as plt
plt.imshow(z, origin='lower', interpolation='none')
plt.show()

So np.meshgrid is just a convenience. In principle the same could be done by:

z2 = sinus2d(np.linspace(0,2*np.pi,100)[:,None], np.linspace(0,2*np.pi,100)[None,:])

but there you need to be aware of your dimensions (suppose you have more than two ...) and the right broadcasting. np.meshgrid does all of this for you.

Also meshgrid allows you to delete coordinates together with the data if you, for example, want to do an interpolation but exclude certain values:

condition = z>0.6
z_new = z[condition] # This will make your array 1D

so how would you do the interpolation now? You can give x and y to an interpolation function like scipy.interpolate.interp2d so you need a way to know which coordinates were deleted:

x_new = xx[condition]
y_new = yy[condition]

and then you can still interpolate with the "right" coordinates (try it without the meshgrid and you will have a lot of extra code):

from scipy.interpolate import interp2d
interpolated = interp2d(x_new, y_new, z_new)

and the original meshgrid allows you to get the interpolation on the original grid again:

interpolated_grid = interpolated(xx[0], yy[:, 0]).reshape(xx.shape)

These are just some examples where I used the meshgrid there might be a lot more.

Logical exclusive-or in Java is called !=. You can also use ^ if you want to confuse your friends.

I've tried so many of the answers here but none of them works, so I decided to mix some of the answers here and I am successful!

Step 1: Go to the system properties by right-clicking on My Computer or by pressing windows button on typing This PC and right clicking on it and selecting Properties.

Step 2: Click the advanced system settings or Environment Variables

Step 3: Take note that there are 2 different variable. What you need to create is system variables not user variables, when you clicked new type the following

Variable name: JAVA_HOME

Variable value: C:\Program Files\Java\jdk1.8.0_25\ (Note: Please check if the path is right, sometimes it is C:\Program Files (x86)\Java\jdk1.8.0_25)

Step 4: Run the android studio, no need to restart.

Note:

*C:\Program Files\Java\jdk1.8.0_25\ depends entirely on the installation path of your JDK not JRE so don't be confused if you see something like the picture below. Just enter the location of your jdk, in my case it is C:\Program Files\Java\jdk1.8.0_25\.

*Do not include the bin folder when you enter the Variable value.

Edit: For Windows 8 and 10 Users: Try to run C:\Program Files\Android\Android Studio\bin\studio.exe instead of C:\Program Files\Android\Android Studio\binstudio64.exe

echo ""

myArray=( "$@" )

echo "A Val 0: ${myArray[0]}"
echo "A Val 1: ${myArray[1]}"
echo "A Val 2: ${myArray[2]}"
echo "A All Values: ${myArray[@]}"

Input:

./bash-array-practice.sh 1 2 3 4

Output:

Theres the ByteArrayInputStream.

It does exactly this.

Here is my attempt: The first select presents the csv field to the split. Using recursive CTE, we can create a list of numbers that are limited to the number of terms in the csv field. The number of terms is just the difference in the length of the csv field and itself with all the delimiters removed. Then joining with this numbers, substring_index extracts that term.

with recursive
    T as ( select 'a,b,c,d,e,f' as items),
    N as ( select 1 as n union select n + 1 from N, T
        where n <= length(items) - length(replace(items, ',', '')))
    select distinct substring_index(substring_index(items, ',', n), ',', -1)
group_name from N, T

I think previous responses defined very well what MixIns are. However, in order to better understand them, it might be useful to compare MixIns with Abstract Classes and Interfaces from the code/implementation perspective:

1. Abstract Class

• Class that needs to contain one or more abstract methods

• Abstract Class can contain state (instance variables) and non-abstract methods

2. Interface

• Interface contains abstract methods only (no non-abstract methods and no internal state)

3. MixIns

• MixIns (like Interfaces) do not contain internal state (instance variables)
• MixIns contain one or more non-abstract methods (they can contain non-abstract methods unlike interfaces)

In e.g. Python these are just conventions, because all of the above are defined as classes. However, the common feature of both Abstract Classes, Interfaces and MixIns is that they should not exist on their own, i.e. should not be instantiated.

You can use the official Slider in the Material Components Library.

Use the app:trackHeight="xxdp" (default value is 4dp) to change the height of the track bar.

Also use these attributes to customize the colors:

• app:activeTrackColor: the active track color
• app:inactiveTrackColor: the inactive track color
• app:thumbColor: to fill the thumb

Something like:

    <com.google.android.material.slider.Slider
        android:id="@+id/slider"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        app:activeTrackColor="#ffd400"
        app:inactiveTrackColor="#e7e7e7"
        app:thumbColor="#ffb300"
        app:trackHeight="12dp"
        .../>

It requires the version 1.2.0 of the library.

android:drawablePadding will only create a padding gap between the text and the drawable if the button is small enough to squish the 2 together. If your button is wider than the combined width (for drawableLeft/drawableRight) or height (for drawableTop/drawableBottom) then drawablePadding doesn't do anything.

I'm struggling with this right now as well. My buttons are quite wide, and the icon is hanging on the left edge of the button and the text is centered in the middle. My only way to get around this for now has been to bake in a margin on the drawable by adding blank pixels to the left edge of the canvas with photoshop. Not ideal, and not really recommended either. But thats my stop-gap solution for now, short of rebuilding TextView/Button.

With safety-mirror on the classpath you get something similar to C#'s delegates and events.

Examples from the project's README:

Delegates in Java!

  Delegate.With1Param<String, String> greetingsDelegate = new Delegate.With1Param<>();
  greetingsDelegate.add(str -> "Hello " + str);
  greetingsDelegate.add(str -> "Goodbye " + str);

  DelegateInvocationResult<String> invocationResult = 
  greetingsDelegate.invokeAndAggregateExceptions("Sir");

  invocationResult.getFunctionInvocationResults().forEach(funInvRes -> 

  System.out.println(funInvRes.getResult()));
  //prints: "Hello sir" and "Goodbye Sir"

Events

  //Create a private Delegate. Make sure it is private so only *you* can invoke it.
  private static Delegate.With0Params<String> trimDelegate = new Delegate.With0Params<>();

  //Create a public Event using the delegate you just created.
  public static Event.With0Params<String> trimEvent= new Event.With0Params<>(trimDelegate)

Alternate Vanilla JS version with click outside to hide checkboxes:

let expanded = false;
const multiSelect = document.querySelector('.multiselect');

multiSelect.addEventListener('click', function(e) {
  const checkboxes = document.getElementById("checkboxes");
    if (!expanded) {
    checkboxes.style.display = "block";
    expanded = true;
  } else {
    checkboxes.style.display = "none";
    expanded = false;
  }
  e.stopPropagation();
}, true)

document.addEventListener('click', function(e){
  if (expanded) {
    checkboxes.style.display = "none";
    expanded = false;
  }
}, false)

I'm using addEventListener instead of onClick in order to take advantage of the capture/bubbling phase options along with stopPropagation(). You can read more about the capture/bubbling here: https://developer.mozilla.org/en-US/docs/Web/API/EventTarget/addEventListener

The rest of the code matches vitfo's original answer (but no need for onclick() in the html). A couple of people have requested this functionality sans jQuery.

Here's codepen example https://codepen.io/davidysoards/pen/QXYYYa?editors=1010

Try this:

ORDER BY 1, 2

OR

ORDER BY rsc.RadioServiceCodeId, rsc.RadioServiceCode + ' - ' + rsc.RadioService

This worked for me, as documented on this page:

TransformerFactory tf = TransformerFactory.newInstance();
Transformer trans = tf.newTransformer();
StringWriter sw = new StringWriter();
trans.transform(new DOMSource(document), new StreamResult(sw));
return sw.toString();

TL;DR

Short, clear and clean: use len(df)

len() is your friend, and it can be used for row counts as len(df).

Alternatively, you can access all rows by df.index and all columns by df.columns, and as you can use the len(anyList) for getting the count of list, use len(df.index) for getting the number of rows, and len(df.columns) for the column count.

Or, you can use df.shape which returns the number of rows and columns together. If you want to access the number of rows, only use df.shape[0]. For the number of columns, only use: df.shape[1].

You can use any of these two:

return redirect()->back()->withInput(Input::all())->with('message', 'Some message');

Or,

return redirect('url_goes_here')->withInput(Input::all())->with('message', 'Some message');

Not possible, I believe ie has a content changed event but it is certainly not x-browser

Should I say not possible without some nasty interval chugging away in the background!

// this is how you shorten the length of the string with .. // add following method to your class

private String abbreviate(String s){
  if(s.length() <= 10) return s;
  return s.substring(0, 8) + ".." ;
}

In case if you want to check whether file does not contain a specific string, you can do it as follows.

if ! grep -q SomeString "$File"; then
  Some Actions # SomeString was not found
fi

If you want to send data from one to another viewController, here's a way to do it:

Say we have viewControllers: viewControllerA and viewControllerB

Now in file viewControllerB.h

@interface viewControllerB : UIViewController {

  NSString *string;
  NSArray *array;

}

- (id)initWithArray:(NSArray)a andString:(NSString)s;

In file viewControllerB.m:

#import "viewControllerB.h"

@implementation viewControllerB

- (id)initWithArray:(NSArray)a andString:(NSString)s {

   array = [[NSArray alloc] init];
   array = a;

   string = [[NSString alloc] init];
   string = s;

}

In file viewControllerA.m:

#import "viewControllerA.h"
#import "viewControllerB.h"

@implementation viewControllerA

- (void)someMethod {

  someArray = [NSArray arrayWithObjects:@"One", @"Two", @"Three", nil];
  someString = [NSString stringWithFormat:@"Hahahahaha"];

  viewControllerB *vc = [[viewControllerB alloc] initWithArray:someArray andString:someString];

  [self.navigationController pushViewController:vc animated:YES];
  [vc release];
}

So this is how you can pass data from viewControllerA to viewControllerB without setting any delegate. ;)

Normally, you'd get an RST if you do a close which doesn't linger (i.e. in which data can be discarded by the stack if it hasn't been sent and ACK'd) and a normal FIN if you allow the close to linger (i.e. the close waits for the data in transit to be ACK'd).

Perhaps all you need to do is set your socket to linger so that you remove the race condition between a non lingering close done on the socket and the ACKs arriving?

ran across this page and several like it all talking about the GIT_DISCOVERY_ACROSS_FILESYSTEM not set message. In my case our sys admin had decided that the apache2 directory needed to be on a mounted filesystem in case the disk for the server stopped working and had to get rebuilt. I found this with a simple df command:

as for react-router-dom 4.x.x (https://www.npmjs.com/package/react-router-dom) you can pass params to the component to route to via:

<Route path="/ideas/:value" component ={CreateIdeaView} />

linking via (considering testValue prop is passed to the corresponding component (e.g. the above App component) rendering the link)

<Link to={`/ideas/${ this.props.testValue }`}>Create Idea</Link>

passing props to your component constructor the value param will be available via

props.match.params.value

Short form:

.zip is an archive format using, usually, the Deflate compression method. The .gz gzip format is for single files, also using the Deflate compression method. Often gzip is used in combination with tar to make a compressed archive format, .tar.gz. The zlib library provides Deflate compression and decompression code for use by zip, gzip, png (which uses the zlib wrapper on deflate data), and many other applications.

Long form:

The ZIP format was developed by Phil Katz as an open format with an open specification, where his implementation, PKZIP, was shareware. It is an archive format that stores files and their directory structure, where each file is individually compressed. The file type is .zip. The files, as well as the directory structure, can optionally be encrypted.

The ZIP format supports several compression methods:

    0 - The file is stored (no compression)
    1 - The file is Shrunk
    2 - The file is Reduced with compression factor 1
    3 - The file is Reduced with compression factor 2
    4 - The file is Reduced with compression factor 3
    5 - The file is Reduced with compression factor 4
    6 - The file is Imploded
    7 - Reserved for Tokenizing compression algorithm
    8 - The file is Deflated
    9 - Enhanced Deflating using Deflate64(tm)
   10 - PKWARE Data Compression Library Imploding (old IBM TERSE)
   11 - Reserved by PKWARE
   12 - File is compressed using BZIP2 algorithm
   13 - Reserved by PKWARE
   14 - LZMA
   15 - Reserved by PKWARE
   16 - IBM z/OS CMPSC Compression
   17 - Reserved by PKWARE
   18 - File is compressed using IBM TERSE (new)
   19 - IBM LZ77 z Architecture 
   20 - deprecated (use method 93 for zstd)
   93 - Zstandard (zstd) Compression 
   94 - MP3 Compression 
   95 - XZ Compression 
   96 - JPEG variant
   97 - WavPack compressed data
   98 - PPMd version I, Rev 1
   99 - AE-x encryption marker (see APPENDIX E)

Methods 1 to 7 are historical and are not in use. Methods 9 through 98 are relatively recent additions and are in varying, small amounts of use. The only method in truly widespread use in the ZIP format is method 8, Deflate, and to some smaller extent method 0, which is no compression at all. Virtually every .zip file that you will come across in the wild will use exclusively methods 8 and 0, likely just method 8. (Method 8 also has a means to effectively store the data with no compression and relatively little expansion, and Method 0 cannot be streamed whereas Method 8 can be.)

The ISO/IEC 21320-1:2015 standard for file containers is a restricted zip format, such as used in Java archive files (.jar), Office Open XML files (Microsoft Office .docx, .xlsx, .pptx), Office Document Format files (.odt, .ods, .odp), and EPUB files (.epub). That standard limits the compression methods to 0 and 8, as well as other constraints such as no encryption or signatures.

Around 1990, the Info-ZIP group wrote portable, free, open-source implementations of zip and unzip utilities, supporting compression with the Deflate format, and decompression of that and the earlier formats. This greatly expanded the use of the .zip format.

In the early '90s, the gzip format was developed as a replacement for the Unix compress utility, derived from the Deflate code in the Info-ZIP utilities. Unix compress was designed to compress a single file or stream, appending a .Z to the file name. compress uses the LZW compression algorithm, which at the time was under patent and its free use was in dispute by the patent holders. Though some specific implementations of Deflate were patented by Phil Katz, the format was not, and so it was possible to write a Deflate implementation that did not infringe on any patents. That implementation has not been so challenged in the last 20+ years. The Unix gzip utility was intended as a drop-in replacement for compress, and in fact is able to decompress compress-compressed data (assuming that you were able to parse that sentence). gzip appends a .gz to the file name. gzip uses the Deflate compressed data format, which compresses quite a bit better than Unix compress, has very fast decompression, and adds a CRC-32 as an integrity check for the data. The header format also permits the storage of more information than the compress format allowed, such as the original file name and the file modification time.

Though compress only compresses a single file, it was common to use the tar utility to create an archive of files, their attributes, and their directory structure into a single .tar file, and to then compress it with compress to make a .tar.Z file. In fact, the tar utility had and still has an option to do the compression at the same time, instead of having to pipe the output of tar to compress. This all carried forward to the gzip format, and tar has an option to compress directly to the .tar.gz format. The tar.gz format compresses better than the .zip approach, since the compression of a .tar can take advantage of redundancy across files, especially many small files. .tar.gz is the most common archive format in use on Unix due to its very high portability, but there are more effective compression methods in use as well, so you will often see .tar.bz2 and .tar.xz archives.

Unlike .tar, .zip has a central directory at the end, which provides a list of the contents. That and the separate compression provides random access to the individual entries in a .zip file. A .tar file would have to be decompressed and scanned from start to end in order to build a directory, which is how a .tar file is listed.

Shortly after the introduction of gzip, around the mid-1990s, the same patent dispute called into question the free use of the .gif image format, very widely used on bulletin boards and the World Wide Web (a new thing at the time). So a small group created the PNG losslessly compressed image format, with file type .png, to replace .gif. That format also uses the Deflate format for compression, which is applied after filters on the image data expose more of the redundancy. In order to promote widespread usage of the PNG format, two free code libraries were created. libpng and zlib. libpng handled all of the features of the PNG format, and zlib provided the compression and decompression code for use by libpng, as well as for other applications. zlib was adapted from the gzip code.

All of the mentioned patents have since expired.

The zlib library supports Deflate compression and decompression, and three kinds of wrapping around the deflate streams. Those are: no wrapping at all ("raw" deflate), zlib wrapping, which is used in the PNG format data blocks, and gzip wrapping, to provide gzip routines for the programmer. The main difference between zlib and gzip wrapping is that the zlib wrapping is more compact, six bytes vs. a minimum of 18 bytes for gzip, and the integrity check, Adler-32, runs faster than the CRC-32 that gzip uses. Raw deflate is used by programs that read and write the .zip format, which is another format that wraps around deflate compressed data.

zlib is now in wide use for data transmission and storage. For example, most HTTP transactions by servers and browsers compress and decompress the data using zlib, specifically HTTP header Content-Encoding: deflate means deflate compression method wrapped inside the zlib data format.

Different implementations of deflate can result in different compressed output for the same input data, as evidenced by the existence of selectable compression levels that allow trading off compression effectiveness for CPU time. zlib and PKZIP are not the only implementations of deflate compression and decompression. Both the 7-Zip archiving utility and Google's zopfli library have the ability to use much more CPU time than zlib in order to squeeze out the last few bits possible when using the deflate format, reducing compressed sizes by a few percent as compared to zlib's highest compression level. The pigz utility, a parallel implementation of gzip, includes the option to use zlib (compression levels 1-9) or zopfli (compression level 11), and somewhat mitigates the time impact of using zopfli by splitting the compression of large files over multiple processors and cores.

This works perfectly:

for /f "usebackq tokens=2,*" %A in (`reg query HKCU\Environment /v PATH`) do set my_user_path=%B

setx PATH "C:\Python27;C:\Python27\Scripts;%my_user_path%"

The 1st command gets the USER environment variable 'PATH', into 'my_user_path' variable The 2nd line prepends the 'C:\Python27;C:\Python27\Scripts;' to the USER environment variable 'PATH'

There are multiple ways to achieve this one:-

1. Add $rootScope in .run method

.run(function ($rootScope) {
    $rootScope.name = "Peter";
});

// Controller
.controller('myController', function ($scope,$rootScope) {
    console.log("Name in rootscope ",$rootScope.name);
    OR
    console.log("Name in scope ",$scope.name);
});

2. Create one service and access it in both the controllers.

.factory('myFactory', function () {
     var object = {};

     object.users = ['John', 'James', 'Jake']; 

     return object;
})
// Controller A

.controller('ControllerA', function (myFactory) {
    console.log("In controller A ", myFactory);
})

// Controller B

.controller('ControllerB', function (myFactory) {
    console.log("In controller B ", myFactory);
})

Just call moment as a function without any arguments:

moment()

For timezone information with moment, look at the moment-timezone package: http://momentjs.com/timezone/

This seems to be answered - #include <fstream>.

The message means :-

incomplete type - the class has not been defined with a full class. The compiler has seen statements such as class ifstream; which allow it to understand that a class exists, but does not know how much memory the class takes up.

The forward declaration allows the compiler to make more sense of :-

void BindInput( ifstream & inputChannel ); 

It understands the class exists, and can send pointers and references through code without being able to create the class, see any data within the class, or call any methods of the class.

The has initializer seems a bit extraneous, but is saying that the incomplete object is being created.

i use it like this:

printf("my number is 0x%02X\n",number);
// output: my number is 0x4A

Just change number "2" to any number of chars You want to print ;)

Basically: try Googling?

You don't need to have a reportViewer control anywhere - you can create the LocalReport on the fly:

var lr = new LocalReport
{
    ReportPath = Path.Combine(Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location) ?? @"C:\", "Reports", "PathOfMyReport.rdlc"),
    EnableExternalImages = true
};

lr.DataSources.Add(new ReportDataSource("NameOfMyDataSet", model));

string mimeType, encoding, extension;

Warning[] warnings;
string[] streams;
var renderedBytes = lr.Render
    (
        "PDF",
        @"<DeviceInfo><OutputFormat>PDF</OutputFormat><HumanReadablePDF>False</HumanReadablePDF></DeviceInfo>",
        out mimeType,
        out encoding,
        out extension,
        out streams,
        out warnings
    );

var saveAs = string.Format("{0}.pdf", Path.Combine(tempPath, "myfilename"));

var idx = 0;
while (File.Exists(saveAs))
{
    idx++;
    saveAs = string.Format("{0}.{1}.pdf", Path.Combine(tempPath, "myfilename"), idx);
}

using (var stream = new FileStream(saveAs, FileMode.Create, FileAccess.Write))
{
    stream.Write(renderedBytes, 0, renderedBytes.Length);
    stream.Close();
}

lr.Dispose();

You can also add parameters: (lr.SetParameter()), handle subreports: (lr.SubreportProcessing+=YourHandler), or pretty much anything you can think of.

if(Locale.getDefault().getDisplayName().equals("?????? (????)")){
    // your code here
}

getResourceAsStream is the right way to do it for web apps (as you already learned).

The reason is that reading from the file system cannot work if you package your web app in a WAR. This is the proper way to package a web app. It's portable that way, because you aren't dependent on an absolute file path or the location where your app server is installed.

React Native is for mobile applications while React is for websites(front-end). Both are frameworks invented by Facebook. React Native is a cross platform developing framework meaning one could write almost the same code for both IOS and Android and it would work. I personally know much more about React Native so I will leave it at this.

I would start with upgrade of CMAKE version.

You can use INCLUDE_DIRECTORIES for header location and LINK_DIRECTORIES + TARGET_LINK_LIBRARIES for libraries

INCLUDE_DIRECTORIES(your/header/dir)
LINK_DIRECTORIES(your/library/dir)
rosbuild_add_executable(kinectueye src/kinect_ueye.cpp)
TARGET_LINK_LIBRARIES(kinectueye lib1 lib2 lib2 ...)

note that lib1 is expanded to liblib1.so (on Linux), so use ln to create appropriate links in case you do not have them

If anyone is curious on how to create a custom error and get the stack trace:

function CustomError(message) {
  this.name = 'CustomError';
  this.message = message || '';
  var error = new Error(this.message);
  error.name = this.name;
  this.stack = error.stack;
}
CustomError.prototype = Object.create(Error.prototype);

try {
  throw new CustomError('foobar');
}
catch (e) {
  console.log('name:', e.name);
  console.log('message:', e.message);
  console.log('stack:', e.stack);
}

You can use GetExitCodeProcess. It will return STILL_ACTIVE (259) if the process is still running (or if it happened to exit with that exit code :( ).

You should enable the management plugin.

rabbitmq-plugins enable rabbitmq_management

See here:

http://www.rabbitmq.com/plugins.html

And here for the specifics of management.

http://www.rabbitmq.com/management.html

Finally once set up you will need to follow the instructions below to install and use the rabbitmqadmin tool. Which can be used to fully interact with the system. http://www.rabbitmq.com/management-cli.html

For example:

rabbitmqadmin get queue=<QueueName> requeue=false

will give you the first message off the queue.

The following simply returns 4 as an answer. When you replace the add expressions for strings it returns the first string.

Function StartingMain {
  $a = 1 + 3
  $b = 2 + 5
  $c = 3 + 7
  Return $a
}

Function StartingEnd($b) {
  Write-Host $b
}

StartingEnd(StartingMain)

This can also be done for an array. The example below will return "Text 2"

Function StartingMain {
  $a = ,@("Text 1","Text 2","Text 3")
  Return $a
}

Function StartingEnd($b) {
  Write-Host $b[1]
}

StartingEnd(StartingMain)

Note that you have to call the function below the function itself. Otherwise, the first time it runs it will return an error that it doesn't know what "StartingMain" is.

If my compiler is set to 32 bit, size_t is nothing other than a typedef for unsigned int. If my compiler is set to 64 bit, size_t is nothing other than a typedef for unsigned long long.

<link rel="shortcut icon" type="image/x-icon" href="favicon.ico" />

add this to your HTML Head. Of course the file "favicon.ico" has to exist. I think 16x16 or 32x32 pixel files are best.

Does your find have the -mmin option? That can let you test the number of mins since last modification:

find $LOCATION -name $REQUIRED_FILES -type f -mmin +360 -delete

Or maybe look at using tmpwatch to do the same job. phjr also recommended tmpreaper in the comments.

Use ix operator:

print df.ix[159220]

Try the below code:

Sub opendfiles()

Dim myfile As Variant
Dim counter As Integer
Dim path As String

myfolder = "D:\temp\"
ChDir myfolder
myfile = Application.GetOpenFilename(, , , , True)
counter = 1
If IsNumeric(myfile) = True Then
    MsgBox "No files selected"
End If
While counter <= UBound(myfile)
    path = myfile(counter)
    Workbooks.Open path
    counter = counter + 1
Wend

End Sub

I just use:

$('body').animate({ 'scrollTop': '-=-'+<yourValueScroll>+'px' }, 2000);

The solution for those who cannot or do not want to wrap the table in a div (e.g. if the HTML is generated from Markdown) but still want to have scrollbars:

table {_x000D_
  display: block;_x000D_
  max-width: -moz-fit-content;_x000D_
  max-width: fit-content;_x000D_
  margin: 0 auto;_x000D_
  overflow-x: auto;_x000D_
  white-space: nowrap;_x000D_
}

<table>_x000D_
  <tr>_x000D_
    <td>Especially on mobile, a table can easily become wider than the viewport.</td>_x000D_
    <td>Using the right CSS, you can get scrollbars on the table without wrapping it.</td>_x000D_
  </tr>_x000D_
</table>_x000D_
_x000D_
<table>_x000D_
  <tr>_x000D_
    <td>A centered table.</td>_x000D_
  </tr>_x000D_
</table>

Explanation: display: block; makes it possible to have scrollbars. By default (and unlike tables), blocks span the full width of the parent element. This can be prevented with max-width: fit-content;, which allows you to still horizontally center tables with less content using margin: 0 auto;. white-space: nowrap; is optional (but useful for this demonstration).

A funny solution

import pandas as pd
list(pd.DataFrame({'lists':l})['lists'].explode())


[1, 2, 3, 4, 5, 6, 7, 8, 9]

Try the Content-Disposition header

Content-Disposition: attachment; filename=<file name.ext> 

You can open up terminal and simply type

java -version // this will check your jre version
javac -version // this will check your java compiler version if you installed 

this should show you the version of java installed on the system (assuming that you have set the path of the java in system environment).

And if you haven't, add it via

export JAVA_HOME=/path/to/java/jdk1.x

and if you unsure if you have java at all on your system just use find in terminal

i.e. find / -name "java"

The code is fine just setStyle of paint as STROKE

paint.setStyle(Paint.Style.STROKE);

Have a look to this wiki: LaTeX/Labels and Cross-referencing:

The hyperref package automatically includes the nameref package, and a similarly named command. It inserts text corresponding to the section name, for example:

\section{MyFirstSection}
\label{marker}
\section{MySecondSection} In section \nameref{marker} we defined...

For UTC:

string unixTimestamp = Convert.ToString((int)DateTime.UtcNow.Subtract(new DateTime(1970, 1, 1)).TotalSeconds);

For local system:

string unixTimestamp = Convert.ToString((int)DateTime.Now.Subtract(new DateTime(1970, 1, 1)).TotalSeconds);

There is no difference until you compile to same target architecture. I suppose you are compiling for 32 bit architecture in both cases.

It's worth mentioning that OutOfMemoryException can also be raised if you get 2GB of memory allocated by a single collection in CLR (say List<T>) on both architectures 32 and 64 bit.

To be able to benefit from memory goodness on 64 bit architecture, you have to compile your code targeting 64 bit architecture. After that, naturally, your binary will run only on 64 bit, but will benefit from possibility having more space available in RAM.

Pandas >= 0.21

set_value has been deprecated. You can now use DataFrame.at to set by label, and DataFrame.iat to set by integer position.

Setting Cell Values with at/iat

# Setup
df = pd.DataFrame({'A': [12, 23], 'B': [['a', 'b'], ['c', 'd']]})
df

    A       B
0  12  [a, b]
1  23  [c, d]

df.dtypes

A     int64
B    object
dtype: object

If you want to set a value in second row of the "B" to some new list, use DataFrane.at:

df.at[1, 'B'] = ['m', 'n']
df

    A       B
0  12  [a, b]
1  23  [m, n]

You can also set by integer position using DataFrame.iat

df.iat[1, df.columns.get_loc('B')] = ['m', 'n']
df

    A       B
0  12  [a, b]
1  23  [m, n]

What if I get ValueError: setting an array element with a sequence?

I'll try to reproduce this with:

df

    A   B
0  12 NaN
1  23 NaN

df.dtypes

A      int64
B    float64
dtype: object

df.at[1, 'B'] = ['m', 'n']
# ValueError: setting an array element with a sequence.

This is because of a your object is of float64 dtype, whereas lists are objects, so there's a mismatch there. What you would have to do in this situation is to convert the column to object first.

df['B'] = df['B'].astype(object)
df.dtypes

A     int64
B    object
dtype: object

Then, it works:

df.at[1, 'B'] = ['m', 'n']
df

    A       B
0  12     NaN
1  23  [m, n]

Possible, But Hacky

Even more wacky, I've found you can hack through DataFrame.loc to achieve something similar if you pass nested lists.

df.loc[1, 'B'] = [['m'], ['n'], ['o'], ['p']]
df

    A             B
0  12        [a, b]
1  23  [m, n, o, p]

You can read more about why this works here.

@Before(JUnit4) -> @BeforeEach(JUnit5) - method is called before every test

@After(JUnit4) -> @AfterEach(JUnit5) - method is called after every test

@BeforeClass(JUnit4) -> @BeforeAll(JUnit5) - static method is called before executing all tests in this class. It can be a large task as starting server, read file, making db connection...

@AfterClass(JUnit4) -> @AfterAll(JUnit5) - static method is called after executing all tests in this class.

I have the same problem and I solved it by adding package to explore to the Jaxb2marshaller. For spring will be define a bean like this:

@Bean
    public Jaxb2Marshaller marshaller() {
        Jaxb2Marshaller marshaller = new Jaxb2Marshaller();
        String[] packagesToScan= {"<packcge which contain the department class>"};
        marshaller.setPackagesToScan(packagesToScan);
        return marshaller;
    }

By this way if all your request and response classes are in the same package you do not need to specifically indicate the classes on the JAXBcontext

had this problem in kali. deleted go and reinstalled and now it works perfectly.

The MessageBox in the Extended WPF Toolkit is very nice. It's at Microsoft.Windows.Controls.MessageBox after referencing the toolkit DLL. Of course this was released Aug 9 2011 so it would not have been an option for you originally. It can be found at Github for everyone out there looking around.

The concept of creating or dropping a database is not meaningful for an embedded database engine like SQLite. It only has meaning with a client-sever database system, such as used by MySQL or Postgres.

To create a new database, just do sqlite_open() or from the command line sqlite3 databasefilename.

To drop a database, delete the file.

Reference: sqlite - Unsupported SQL

I would disagree with converting it on the server side. If you do that it's going to come back as a string type rather than a date type with all that entails (it will sort as a string for example)

My principle when dealing with dates is to keep them typed as a date for as long as you possibly can.

If your facing a performance bottleneck on the report server there are better ways to handle it than compromising your logic.

You can fill the <td/> elements with <div/> elements, and apply any margin to those divs that you like. For a visual space between the rows, you can use a repeating background image on the <tr/> element. (This was the solution I just used today, and it appears to work in both IE6 and FireFox 3, though I didn't test it any further.)

Also, if you're averse to modifying your server code to put <div/>s inside the <td/>s, you can use jQuery (or something similar) to dynamically wrap the <td/> contents in a <div/>, enabling you to apply the CSS as desired.

dat <- data.frame(x1 = c(1,2,3, NA, 5), x2 = c(100, NA, 300, 400, 500))

na.omit(dat)
  x1  x2
1  1 100
3  3 300
5  5 500

This is my solution:

/*
Change dimension of Image
*/
public static Image resizeImage(Image image, int scaledWidth, int scaledHeight, boolean preserveRatio) {  

    if (preserveRatio) { 
        double imageHeight = image.getHeight();
        double imageWidth = image.getWidth();

        if (imageHeight/scaledHeight > imageWidth/scaledWidth) {
            scaledWidth = (int) (scaledHeight * imageWidth / imageHeight);
        } else {
            scaledHeight = (int) (scaledWidth * imageHeight / imageWidth);
        }        
    }                   
    BufferedImage inputBufImage = SwingFXUtils.fromFXImage(image, null);     
    // creates output image
    BufferedImage outputBufImage = new BufferedImage(scaledWidth, scaledHeight, inputBufImage.getType());       
    // scales the input image to the output image
    Graphics2D g2d = outputBufImage.createGraphics();
    g2d.drawImage(inputBufImage, 0, 0, scaledWidth, scaledHeight, null);
    g2d.dispose();      
    return SwingFXUtils.toFXImage(outputBufImage, null);
}

From the use of 8080 I'm assuming you are using a tomcat servlet container to serve your rest api. If this is the case you can also consider to have your webserver proxy the requests to the servlet container.

With apache you would typically use mod_jk (although there are other alternatives) to serve the api trough the web server behind port 80 instead of 8080 which would solve the cross domain issue.

This is common practice, have the 'static' content in the webserver and dynamic content in the container, but both served from behind the same domain.

The url for the rest api would be http://localhost/restws/json/product/get

Here a description on how to use mod_jk to connect apache to tomcat: http://tomcat.apache.org/connectors-doc/webserver_howto/apache.html

How to Use Sockets in JavaScript/HTML?

There is no facility to use general-purpose sockets in JS or HTML. It would be a security disaster, for one.

There is WebSocket in HTML5. The client side is fairly trivial:

socket= new WebSocket('ws://www.example.com:8000/somesocket');
socket.onopen= function() {
    socket.send('hello');
};
socket.onmessage= function(s) {
    alert('got reply '+s);
};

You will need a specialised socket application on the server-side to take the connections and do something with them; it is not something you would normally be doing from a web server's scripting interface. However it is a relatively simple protocol; my noddy Python SocketServer-based endpoint was only a couple of pages of code.

In any case, it doesn't really exist, yet. Neither the JavaScript-side spec nor the network transport spec are nailed down, and no browsers support it.

You can, however, use Flash where available to provide your script with a fallback until WebSocket is widely available. Gimite's web-socket-js is one free example of such. However you are subject to the same limitations as Flash Sockets then, namely that your server has to be able to spit out a cross-domain policy on request to the socket port, and you will often have difficulties with proxies/firewalls. (Flash sockets are made directly; for someone without direct public IP access who can only get out of the network through an HTTP proxy, they won't work.)

Unless you really need low-latency two-way communication, you are better off sticking with XMLHttpRequest for now.

Based on the discussion in the comments (particularly from BalusC), it's probably not worth doing anything more complicated than this:

<script>var ctx = "${pageContext.request.contextPath}"</script>

1. Slowest and doesn't work in Python3: concatenate the items and call dict on the resulting list:

   $ python -mtimeit -s'd1={1:2,3:4}; d2={5:6,7:9}; d3={10:8,13:22}' \
   'd4 = dict(d1.items() + d2.items() + d3.items())'
   
   100000 loops, best of 3: 4.93 usec per loop
   

2. Fastest: exploit the dict constructor to the hilt, then one update:

   $ python -mtimeit -s'd1={1:2,3:4}; d2={5:6,7:9}; d3={10:8,13:22}' \
   'd4 = dict(d1, **d2); d4.update(d3)'
   
   1000000 loops, best of 3: 1.88 usec per loop
   

3. Middling: a loop of update calls on an initially-empty dict:

   $ python -mtimeit -s'd1={1:2,3:4}; d2={5:6,7:9}; d3={10:8,13:22}' \
   'd4 = {}' 'for d in (d1, d2, d3): d4.update(d)'
   
   100000 loops, best of 3: 2.67 usec per loop
   

4. Or, equivalently, one copy-ctor and two updates:

   $ python -mtimeit -s'd1={1:2,3:4}; d2={5:6,7:9}; d3={10:8,13:22}' \
   'd4 = dict(d1)' 'for d in (d2, d3): d4.update(d)'
   
   100000 loops, best of 3: 2.65 usec per loop
   

I recommend approach (2), and I particularly recommend avoiding (1) (which also takes up O(N) extra auxiliary memory for the concatenated list of items temporary data structure).

Are you calling getWidth() before the view is actually laid out on the screen?

A common mistake made by new Android developers is to use the width and height of a view inside its constructor. When a view’s constructor is called, Android doesn’t know yet how big the view will be, so the sizes are set to zero. The real sizes are calculated during the layout stage, which occurs after construction but before anything is drawn. You can use the onSizeChanged() method to be notified of the values when they are known, or you can use the getWidth() and getHeight() methods later, such as in the onDraw() method.

After insertion code,

ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "alertMessage", "alert('Record Inserted Successfully')", true);

Issue:

Encountered with a similar issue for a NuGet package DLL (Newtonsoft.json.dll) where the build output doesn't include the referenced DLL. But the compilation goes thru fine.

Fix:

Go through your projects in a text editor and look for references with "Private" tags in them. Like True or False. “Private” is a synonym for “Copy Local.” Somewhere in the actions, MSBuild is taking to locate dependencies, it’s finding your dependency somewhere else and deciding not to copy it.

So, go through each .csproj/.vbproj file and remove the tags manually. Rebuild, and everything works in both Visual Studio and MSBuild. Once you’ve got that working, you can go back in and update the to where you think they need to be.

Reference:

https://www.paraesthesia.com/archive/2008/02/13/what-to-do-if-copy-local-works-in-vs-but.aspx/

Most of the answers provided here address the number of incoming requests to your backend webservice, not the number of outgoing requests you can make from your ASP.net application to your backend service.

It's not your backend webservice that is throttling your request rate here, it is the number of open connections your calling application is willing to establish to the same endpoint (same URL).

You can remove this limitation by adding the following configuration section to your machine.config file:

<configuration>
  <system.net>
    <connectionManagement>
      <add address="*" maxconnection="65535"/>
    </connectionManagement>
  </system.net>
</configuration>

You could of course pick a more reasonable number if you'd like such as 50 or 100 concurrent connections. But the above will open it right up to max. You can also specify a specific address for the open limit rule above rather than the '*' which indicates all addresses.

MSDN Documentation for System.Net.connectionManagement

Another Great Resource for understanding ConnectManagement in .NET

Hope this solves your problem!

EDIT: Oops, I do see you have the connection management mentioned in your code above. I will leave my above info as it is relevant for future enquirers with the same problem. However, please note there are currently 4 different machine.config files on most up to date servers!

There is .NET Framework v2 running under both 32-bit and 64-bit as well as .NET Framework v4 also running under both 32-bit and 64-bit. Depending on your chosen settings for your application pool you could be using any one of these 4 different machine.config files! Please check all 4 machine.config files typically located here:

The answer of Anuja Patil only works with a single file input on a page. This works if there are more than one. This snippet will also show all files if multiple is enabled.

<script type="text/javascript">

    $('.custom-file input').change(function (e) {
        var files = [];
        for (var i = 0; i < $(this)[0].files.length; i++) {
            files.push($(this)[0].files[i].name);
        }
        $(this).next('.custom-file-label').html(files.join(', '));
    });

</script>

Note that $(this).next('.custom-file-label').html($(this)[0].files.join(', ')); does not work. So that is why the for loop is needed.

If you never work with mulitple files in the file upload, this simpler snippet can be used.

<script type="text/javascript">

    $('.custom-file input').change(function (e) {
        if (e.target.files.length) {
            $(this).next('.custom-file-label').html(e.target.files[0].name);
        }
    });

</script>

Use the Controller's Redirect() method.

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

Update

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

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

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

That works with :

 var element = document.getElementById('myElem');
 if (typeof (element) != undefined && typeof (element) != null && typeof (element) != 'undefined') {
     console.log('element exists');
 }
 else{
     console.log('element NOT exists');
 }

Try the connect by clause in oracle, something like this

select level,level+1,level+2 from dual connect by level <=3;

For more information on connect by clause follow this link : removed URL because oraclebin site is now malicious.

Just one command did the work

netsh http add iplisten 127.0.0.1

As Mark mentioned, the previous statement should be ended in semi-colon. So you can use:

; DISABLE TRIGGER dbo.tr_name ON dbo.table_name

you can render in following way

{{ post.published_at|date("m/d/Y") }}

For more details can visit http://twig.sensiolabs.org/doc/filters/date.html

I suggest you use dialog...

Linux Apprentice: Improve Bash Shell Scripts Using Dialog

The dialog command enables the use of window boxes in shell scripts to make their use more interactive.

it's simple and easy to use, there's also a gnome version called gdialog that takes the exact same parameters, but shows it GUI style on X.

I just realized why I was having so much trouble - in MATLAB you can't store strings of different lengths as an array using square brackets. Using square brackets concatenates strings of varying lengths into a single character array.

    >> a=['matlab','is','fun']

a =

matlabisfun

>> size(a)

ans =

     1    11

In a character array, each character in a string counts as one element, which explains why the size of a is 1X11.

To store strings of varying lengths as elements of an array, you need to use curly braces to save as a cell array. In cell arrays, each string is treated as a separate element, regardless of length.

>> a={'matlab','is','fun'}

a = 

    'matlab'    'is'    'fun'

>> size(a)

ans =

     1     3

Can you place the #ulId in the document prior to the ajax load (with css display: none;), or wrap it in a containing div (with css display: none;), then just load the inner html during ajax page load, that way the scroll event will be linked to the div that is already there prior to the ajax?

Then you can use:

$('#ulId').on('scroll',function(){ console.log('Event Fired'); })

obviously replacing ulId with whatever the actual id of the scrollable div is.

Then set css display: block; on the #ulId (or containing div) upon load?

Oracle

I recommend reading about string aggregation/concatentation in Oracle.

In addition to the ?ShiftU/CtrlShiftU solution, you can also add a link quickly by doing the following:

1. Copy a URL to the clipboard
2. Select the text in a slack message you are writing that you want to be a link
3. Press ?V on Mac or CtrlV

I couldn't find it documented anywhere, but it works, and seems very handy.

Here is a method I use to get the last xx of a string:

public static String takeLast(String value, int count) {
    if (value == null || value.trim().length() == 0) return "";
    if (count < 1) return "";

    if (value.length() > count) {
        return value.substring(value.length() - count);
    } else {
        return value;
    }
}

Then use it like so:

String testStr = "this is a test string";
String last1 = takeLast(testStr, 1); //Output: g
String last4 = takeLast(testStr, 4); //Output: ring

Although I almost always just use pandas for this, my current little tool is being packaged into an executable and including pandas is overkill. So I created a version of poida's solution that resulted in a list of named tuples. His code with this change would look like this:

from xlrd import open_workbook
from collections import namedtuple
from pprint import pprint

wb = open_workbook('sample.xls')

FORMAT = ['Arm_id', 'DSPName', 'PinCode']
OneRow = namedtuple('OneRow', ' '.join(FORMAT))
all_rows = []

for s in wb.sheets():
    headerRow = s.row(0)
    columnIndex = [x for y in FORMAT for x in range(len(headerRow)) if y == headerRow[x].value]

    for row in range(1,s.nrows):
        currentRow = s.row(row)
        currentRowValues = [currentRow[x].value for x in columnIndex]
        all_rows.append(OneRow(*currentRowValues))

pprint(all_rows)

position: relative act as a parent element position: absolute act a child of relative position. you can see the below example

.postion-element{
   position:relative;
   width:200px;
   height:200px;
   background-color:green;
 }
.absolute-element{
  position:absolute;
  top:10px;
  left:10px;
  background-color:blue;
 }

Wow, you have a huge misunderstanding how asp.net works.

This line of code

System.Diagnostics.Process.Start("help/AdminTutorial.html");

Will not redirect a admin user to a new site, but start a new process on the server (usually a browser, IE) and load the site. That is for sure not what you want.

A very easy solution would be to change the href attribute of the link in you page_load method.

Your aspx code:

<a href="#" runat="server" id="myLink">Tutorial</a>

Your codebehind / cs code of page_load:

...
if (userinfo.user == "Admin")
{
  myLink.Attributes["href"] = "help/AdminTutorial.html";
}
else 
{
  myLink.Attributes["href"] = "help/otherSite.html";
}
...

Don't forget to check the Admin rights again on "AdminTutorial.html" to "prevent" hacking.

Just adding this for multiple filters attaching to Q object, if someone might be looking to it. If a Q object is provided, it must precede the definition of any keyword arguments. Otherwise its an invalid query. You should be careful when doing it.

an example would be

from django.db.models import Q
User.objects.filter(Q(income__gte=5000) | Q(income__isnull=True),category='income')

Here the OR condition and a filter with category of income is taken into account

I created dummy sample for Google Maps v2 Android with Kotlin and AndroidX

You can find complete project here: github-link

MainActivity.kt

class MainActivity : AppCompatActivity() {

val position = LatLng(-33.920455, 18.466941)

    setContentView(R.layout.activity_main)

    with(mapView) {
        // Initialise the MapView
        onCreate(null)
        // Set the map ready callback to receive the GoogleMap object
        getMapAsync{
            MapsInitializer.initialize(applicationContext)
            setMapLocation(it)
        }

Depends on what your native code does, but v7a has support for hardware floating point operations, which makes a huge difference. armeabi will work fine on all devices, but will be a lot slower, and won't take advantage of newer devices' CPU capabilities. Do take some benchmarks for your particular application, but removing the armeabi-v7a binaries is generally not a good idea. If you need to reduce size, you might want to have two separate apks for older (armeabi) and newer (armeabi-v7a) devices.

The problem lays here:

--This result set has 3 columns
select LOC_id,LOC_locatie,LOC_deelVan_LOC_id from tblLocatie t
where t.LOC_id = 1 -- 1 represents an example

union all

--This result set has 1 columns   
select t.LOC_locatie + '>' from tblLocatie t
inner join q parent on parent.LOC_id = t.LOC_deelVan_LOC_id

In order to use union or union all number of columns and their types should be identical cross all result sets.

I guess you should just add the column LOC_deelVan_LOC_id to your second result set

If you encounter this error in SourceTree, go to Actions>Resolve Conflicts>Restart Merge.

SourceTree version used is 1.6.14.0

You can return dynamic which will give you a runtime checked version of the anonymous type but only in .NET 4+

If you are floating the elements you can reverse the order

i.e. float: right; instead of float: left;

And then use this method to select the first-child of a class.

/* 1: Apply style to ALL instances */
#header .some-class {
  padding-right: 0;
}
/* 2: Remove style from ALL instances except FIRST instance */
#header .some-class~.some-class {
  padding-right: 20px;
}

This is actually applying the class to the LAST instance only because it's now in reversed order.

Here is a working example for you:

<!doctype html>
<head><title>CSS Test</title>
<style type="text/css">
.some-class { margin: 0; padding: 0 20px; list-style-type: square; }
.lfloat { float: left; display: block; }
.rfloat { float: right; display: block; }
/* apply style to last instance only */
#header .some-class {
  border: 1px solid red;
  padding-right: 0;
}
#header .some-class~.some-class {
  border: 0;
  padding-right: 20px;
}
</style>
</head>
<body>
<div id="header">
  <img src="some_image" title="Logo" class="lfloat no-border"/>
  <ul class="some-class rfloat">
    <li>List 1-1</li>
    <li>List 1-2</li>
    <li>List 1-3</li>
  </ul>
  <ul class="some-class rfloat">
    <li>List 2-1</li>
    <li>List 2-2</li>
    <li>List 2-3</li>
  </ul>
  <ul class="some-class rfloat">
    <li>List 3-1</li>
    <li>List 3-2</li>
    <li>List 3-3</li>
  </ul>
  <img src="some_other_img" title="Icon" class="rfloat no-border"/>
</div>
</body>
</html>

Others have pointed out that a get_FOO_display method is what you need. I'm using this:

def get_type(self):
    return [i[1] for i in Item._meta.get_field('type').choices if i[0] == self.type][0]

which iterates over all of the choices that a particular item has until it finds the one that matches the items type

Another solution would be as below where the list is placed under a drop-down button.

  <button class="btn dropdown-toggle btn-primary btn-sm" data-toggle="dropdown"
    >Markets<span class="caret"></span></button>

    <ul class="dropdown-menu", style="height:40%; overflow:hidden; overflow-y:scroll;">
      {{ form.markets }}
    </ul>

Had to do it in a project without Boost. So, ended up writing my own. I will just put it on GitHub: https://github.com/corporateshark/LUrlParser

clParseURL URL = clParseURL::ParseURL( "https://name:[email protected]:80/path/res" );

if ( URL.IsValid() )
{
    cout << "Scheme    : " << URL.m_Scheme << endl;
    cout << "Host      : " << URL.m_Host << endl;
    cout << "Port      : " << URL.m_Port << endl;
    cout << "Path      : " << URL.m_Path << endl;
    cout << "Query     : " << URL.m_Query << endl;
    cout << "Fragment  : " << URL.m_Fragment << endl;
    cout << "User name : " << URL.m_UserName << endl;
    cout << "Password  : " << URL.m_Password << endl;
}

You can use reject method of Underscore, below will return a new array which won't have array with particular match

arr = _.reject(arr, function(objArr){ return objArr.id == 3; });

The following works well in a .php file.

<php? /*your block you want commented out*/ ?>

If you fiddle with browser versions it leads to no good very often. You don't want to implement it by yourself. But you can Modernizr made by Paul Irish and other smart folks. It will detect what the browser actually can do and put apropriate classes in <html> element. However with Modernizr, you can test IE version like this:

$('html.lt-ie9').each() {
    // this will execute if browser is IE 8 or less
}

Similary, you can use .lt-ie8, and .lt-ie7.

You can try lubridate package which makes life much easier

library(lubridate)

mdy_hms(mydate)

The above will change the date format to POSIXct

A sample working example:

> data <- "1/15/2006 01:15:00"
> library(lubridate)
> mydate <- mdy_hms(data)
> mydate
[1] "2006-01-15 01:15:00 UTC"
> class(mydate)
[1] "POSIXct" "POSIXt" 

For case with factor use as.character

data <- factor("1/15/2006 01:15:00")
library(lubridate)
mydate <- mdy_hms(as.character(data))

May be sometimes upgrading to a superuser might not be a good option. So apart from super user there are lot of other options which you can use. Open your terminal and type the following:

$ sudo su - postgres
[sudo] password for user: (type your password here)
$ psql
postgres@user:~$ psql
psql (10.5 (Ubuntu 10.5-1.pgdg18.04+1))
Type "help" for help.

postgres=# ALTER USER my_user WITH option

Also listing the list of options

SUPERUSER | NOSUPERUSER | CREATEDB | NOCREATEDB  | CREATEROLE | NOCREATEROLE |
CREATEUSER | NOCREATEUSER | INHERIT | NOINHERIT | LOGIN | NOLOGIN | REPLICATION|
NOREPLICATION | BYPASSRLS | NOBYPASSRLS | CONNECTION LIMIT connlimit | 
[ ENCRYPTED | UNENCRYPTED ] PASSWORD 'password' | VALID UNTIL 'timestamp'

So in command line it will look like

postgres=# ALTER USER my_user WITH  LOGIN

OR use an encrypted password.

postgres=# ALTER USER my_user  WITH ENCRYPTED PASSWORD '5d41402abc4b2a76b9719d911017c592';

OR revoke permissions after a specific time.

postgres=# ALTER USER my_user  WITH VALID UNTIL '2019-12-29 19:09:00';

Recognizing this question was asked years ago, I think a more elegant solution is offered on github by frmdstryr using his module pywinutils:

Excerpt:

import pythoncom
from win32com.shell import shell,shellcon

def copy(src,dst,flags=shellcon.FOF_NOCONFIRMATION):
    """ Copy files using the built in Windows File copy dialog

    Requires absolute paths. Does NOT create root destination folder if it doesn't exist.
    Overwrites and is recursive by default 
    @see http://msdn.microsoft.com/en-us/library/bb775799(v=vs.85).aspx for flags available
    """
    # @see IFileOperation
    pfo = pythoncom.CoCreateInstance(shell.CLSID_FileOperation,None,pythoncom.CLSCTX_ALL,shell.IID_IFileOperation)

    # Respond with Yes to All for any dialog
    # @see http://msdn.microsoft.com/en-us/library/bb775799(v=vs.85).aspx
    pfo.SetOperationFlags(flags)

    # Set the destionation folder
    dst = shell.SHCreateItemFromParsingName(dst,None,shell.IID_IShellItem)

    if type(src) not in (tuple,list):
        src = (src,)

    for f in src:
        item = shell.SHCreateItemFromParsingName(f,None,shell.IID_IShellItem)
        pfo.CopyItem(item,dst) # Schedule an operation to be performed

    # @see http://msdn.microsoft.com/en-us/library/bb775780(v=vs.85).aspx

    # @see sdn.microsoft.com/en-us/library/bb775769(v=vs.85).aspx
    aborted = pfo.GetAnyOperationsAborted()
    return success is None and not aborted    

This utilizes the COM interface and automatically indicates that admin privileges are needed with the familiar dialog prompt that you would see if you were copying into a directory where admin privileges are required and also provides the typical file progress dialog during the copy operation.

In parallel with William Pursell's answer, here is a simple construct which should work even in the original v7 Bourne shell (and thus also places where Bash is not available).

i=0
while read line; do
    i=`expr "$i" + 1`
    case $i in 5) echo "$line"; break;; esac
done <file

Notice also the optimization to break out of the loop when we have obtained the line we were looking for.

I've fixed the problem in my case very easy:
go to Build- Path->Configure Build Path->Order and Export and ensure that <project name>/gen folder is above <project name>/src
After fixing the order the error disappears.

Sometimes brew update fails on me because one package doesn't download properly. So you can just upgrade a specific library like this:

brew upgrade node

https://gist.github.com/3005832

If the structs only contain primitives or if you are interested in strict equality then you can do something like this:

int my_struct_cmp(const struct my_struct * lhs, const struct my_struct * rhs)
{
    return memcmp(lhs, rsh, sizeof(struct my_struct));
}

However, if your structs contain pointers to other structs or unions then you will need to write a function that compares the primitives properly and make comparison calls against the other structures as appropriate.

Be aware, however, that you should have used memset(&a, sizeof(struct my_struct), 1) to zero out the memory range of the structures as part of your ADT initialization.

It is this line button2.Enabled == true, it should be button2.Enabled = true. You are doing comparison when you should be doing assignment.

A bit late, but this could also be useful. There is an IE filter, for IE 5.5+, which you can apply:

filter: progid:DXImageTransform.Microsoft.AlphaImageLoader(
src='images/logo.gif',
sizingMethod='scale');

-ms-filter: "progid:DXImageTransform.Microsoft.AlphaImageLoader(
src='images/logo.gif',
sizingMethod='scale')";

However, this scales the entire image to fit in the allocated area, so if you're using a sprite, this may cause issues.

Specification: AlphaImageLoader Filter @microsoft

# Let's add key:value to a dictionary, the functional way

print(dict_obj) 

here's an answer that does follow the syntax of

$(element).hasAnyOfClasses("class1","class2","class3")

(function($){
    $.fn.hasAnyOfClasses = function(){
        for(var i= 0, il=arguments.length; i<il; i++){
            if($self.hasClass(arguments[i])) return true;
        }
        return false;
    }
})(jQuery);

it's not the fastest, but its unambiguous and the solution i prefer. bench: http://jsperf.com/hasclasstest/10

another solution is catching onClick event and for aggregate data to js function you can

.hmtl.erb

<%= link_to "Action", 'javascript:;', class: 'my-class', data: { 'array' => %w(foo bar) } %>

.js

// handle my-class click
$('a.my-class').on('click', function () {
  var link = $(this);
  var array = link.data('array');
});

When a module is loaded from a file in Python, __file__ is set to its path. You can then use that with other functions to find the directory that the file is located in.

Taking your examples one at a time:

A = os.path.join(os.path.dirname(__file__), '..')
# A is the parent directory of the directory where program resides.

B = os.path.dirname(os.path.realpath(__file__))
# B is the canonicalised (?) directory where the program resides.

C = os.path.abspath(os.path.dirname(__file__))
# C is the absolute path of the directory where the program resides.

You can see the various values returned from these here:

import os
print(__file__)
print(os.path.join(os.path.dirname(__file__), '..'))
print(os.path.dirname(os.path.realpath(__file__)))
print(os.path.abspath(os.path.dirname(__file__)))

and make sure you run it from different locations (such as ./text.py, ~/python/text.py and so forth) to see what difference that makes.

I just want to address some confusion first. __file__ is not a wildcard it is an attribute. Double underscore attributes and methods are considered to be "special" by convention and serve a special purpose.

http://docs.python.org/reference/datamodel.html shows many of the special methods and attributes, if not all of them.

In this case __file__ is an attribute of a module (a module object). In Python a .py file is a module. So import amodule will have an attribute of __file__ which means different things under difference circumstances.

Taken from the docs:

__file__ is the pathname of the file from which the module was loaded, if it was loaded from a file. The __file__ attribute is not present for C modules that are statically linked into the interpreter; for extension modules loaded dynamically from a shared library, it is the pathname of the shared library file.

In your case the module is accessing it's own __file__ attribute in the global namespace.

To see this in action try:

# file: test.py

print globals()
print __file__

And run:

python test.py

{'__builtins__': <module '__builtin__' (built-in)>, '__name__': '__main__', '__file__':
 'test_print__file__.py', '__doc__': None, '__package__': None}
test_print__file__.py

As programmers we want the quickest, most fool-proof way to get our tools in order so we can start hacking. Here are how I got it to work in MacOS 10.13.1 (High Sierra):

• Option 1: Go to System Preferences | Keyboard | Shortcut | Services. Under Files and Folders section, enable New Terminal at Folder and/or New Terminal Tab at Folder and assign a shortcut key to it.

• Option 2: If you want the shortcut key to work anywhere, create a new Service using Automator, then go to the Keyboard Shortcut to assign a shortcut key to it. Known limitation: not work from the desktop

Notes:

• If the shortcut doesn't work, it might be in conflict with another key binding (and the OS wouldn't warn you), try something else, e.g. if ??T doesn't work, try ??T.
• Don't spell-correct MacOS, that's not necessary.

1. Go to you package.json

2. Change "react-scripts": "3.x.x" to "react-scripts": "^3.4.0" in the dependencies

3. Reinstall react-scripts: npm I react-scripts

4. Start your project: npm start

In my case I'd install VS.Net 2015 update 2 and left the Windows 8.1 SDK box UNchecked (since I'm now using Windows 10 and didn't think it necessary). However that seems to have resulted in some required registry settings being omitted.

Doing a modify of VS.Net 2015 from the control panel and checking the 8.1 SDK box fixed the problem.

A very simple check you can do with Cell formulas:

Sheet 1 (new - old)

=(if(AND(Ref_New<>"";Ref_Old="");Ref_New;"")

Sheet 2 (old - new)

=(if(AND(Ref_Old<>"";Ref_New="");Ref_Old;"")

This formulas should work for an ENGLISH Excel. For other languages they need to be translated. (For German i can assist)

You need to open all three Excel Documents, then copy the first formula into A1 of your sheet 1 and the second into A1 of sheet 2. Now click in A1 of the first cell and mark "Ref_New", now you can select your reference, go to the new file and click in the A1, go back to sheet1 and do the same for "Ref_Old" with the old file. Replace also the other "Ref_New".

Doe the same for Sheet two.

Now copy the formaula form A1 over the complete range where zour data is in the old and the new file.

But two cases are not covered here:

1. In the compared cell of New and Old is the same data (Resulting Cell will be empty)
2. In the compared cell of New and Old is diffe data (Resulting Cell will be empty)

To cover this two cases also, you should create your own function, means learn VBA. A very useful Excel page is cpearson.com

You can set up a express proxy server using http-proxy-middleware to bypass CORS:

const express = require('express');
const proxy = require('http-proxy-middleware');
const path = require('path');
const port = process.env.PORT || 8080;
const app = express();

app.use(express.static(__dirname));
app.use('/proxy', proxy({
    pathRewrite: {
       '^/proxy/': '/'
    },
    target: 'https://server.com',
    secure: false
}));

app.get('*', (req, res) => {
   res.sendFile(path.resolve(__dirname, 'index.html'));
});

app.listen(port);
console.log('Server started');

From your react app all requests should be sent to /proxy endpoint and they will be redirected to the intended server.

const URL = `/proxy/${PATH}`;
return axios.get(URL);

Select @ModelID =m.modelid 
From   MODELS m
Where  m.areaid = 'South Coast'

In this case if you have two or more results returned then your result is the last record. So be aware of this if you might have two more records returned as you might not see the expected result.

If your error event handler takes the three arguments (xmlhttprequest, textstatus, and message) when a timeout happens, the status arg will be 'timeout'.

Per the jQuery documentation:

Possible values for the second argument (besides null) are "timeout", "error", "notmodified" and "parsererror".

You can handle your error accordingly then.

I created this fiddle that demonstrates this.

$.ajax({
    url: "/ajax_json_echo/",
    type: "GET",
    dataType: "json",
    timeout: 1000,
    success: function(response) { alert(response); },
    error: function(xmlhttprequest, textstatus, message) {
        if(textstatus==="timeout") {
            alert("got timeout");
        } else {
            alert(textstatus);
        }
    }
});?

With jsFiddle, you can test ajax calls -- it will wait 2 seconds before responding. I put the timeout setting at 1 second, so it should error out and pass back a textstatus of 'timeout' to the error handler.

Hope this helps!

There are two steps:

1. Convert interface to JSON Byte
2. Convert JSON Byte to struct

Below is an example:

dbByte, _ := json.Marshal(dbContent)
_ = json.Unmarshal(dbByte, &MyStruct)

I am also suffering from the same issue. In my case I just copied the image to the drawable folder, then Android Studio is showing the error "Some file crunching failed".

My problem regarding to image only because that image was saved from the one of the my customized camera application in .png format. And for testing purposes I copied it into the drawable folder.

After that I tested saving the image as .jpg. It was not giving any error. That means the camera by default supports the ".jpg" format.

Finally I realized two things:

1. The camera by default supports the ".jpg" format

2. Without using image tools, don't change the image formats (even programmatically).

The default value is indeed false.

However you can't use a local variable is it's not been assigned first.

You can use the default keyword to verify:

bool foo = default(bool);
if (!foo) { Console.WriteLine("Default is false"); }

For me both these methods didn't work:

• navigationView.getMenu().getItem(0).setChecked(true);
• navigationView.setCheckedItem(id);

Try this one, it works for me.

onNavigationItemSelected(navigationView.getMenu().findItem(R.id.nav_profile));

Solutions revolve around:

• changing MySQL's permissions

  sudo chown -R _mysql:mysql /usr/local/var/mysql
  

• Starting a MySQL process

  sudo mysql.server start
  

Just to add on a lot of great and useful answers that have been provided here and from many different posts, try specifying the host if the above commands did not resolve this issue for you, i.e

mysql -u root -p h127.0.0.1

mkdir ~/bin
PATH=~/bin:$PATH
ln -s /usr/bin/python2 ~/bin/python

To stop using python2, exit or rm ~/bin/python.

var = None "clears the value", setting the value of the variable to "null" like value of "None", however the pointer to the variable remains.

del var removes the definition for the variable totally.

In case you want to use the variable later, e.g. set a new value for it, i.e. retain the variable, None would be better.

The colorbar has to have its own axes. However, you can create an axes that overlaps with the previous one. Then use the cax kwarg to tell fig.colorbar to use the new axes.

For example:

import numpy as np
import matplotlib.pyplot as plt

data = np.arange(100, 0, -1).reshape(10, 10)

fig, ax = plt.subplots()
cax = fig.add_axes([0.27, 0.8, 0.5, 0.05])

im = ax.imshow(data, cmap='gist_earth')
fig.colorbar(im, cax=cax, orientation='horizontal')
plt.show()

To install Python package from github, you need to clone that repository.

git clone https://github.com/jkbr/httpie.git

Then just run the setup.py file from that directory,

sudo python setup.py install

I know it's not the exact answer to this question, but I found this thread after hunting the internet down for an answer. I assume others share that feeling.

This is my variance of the UITapGestureRecognizer which I find reliable and easy to use - just set the delegate of the TextView to the ViewController.

Instead of ViewDidLoad I add the UITapGestureRecognizer when the TextView becomes active for editing:

-(void)textViewDidBeginEditing:(UITextView *)textView{
    _tapRec = [[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(tap:)];

    [self.view addGestureRecognizer: _tapRec];
    NSLog(@"TextView Did begin");
}

When I tap outside the TextView, the view ends editing mode and the UITapGestureRecognizer removes itself so I can continue interacting with other controls in the view.

-(void)tap:(UITapGestureRecognizer *)tapRec{
    [[self view] endEditing: YES];
    [self.view removeGestureRecognizer:tapRec];
    NSLog(@"Tap recognized, tapRec getting removed");
}

I hope this helps. It seems so obvious but I have never seen this solution anywhere on the web - am I doing something wrong?

I have converted to using Powershell calls for this purpose in my scripts. It requires script execution permission and is by far the slowest option. However it is also localization independent, very easy to write and read, and it is much more feasible to perform adjustments to the date like addition/subtraction or get the last day of the month, etc.

Here is how to get the day, month, and year

for /f %%i in ('"powershell (Get-Date).ToString(\"dd\")"') do set day=%%i
for /f %%i in ('"powershell (Get-Date).ToString(\"MM\")"') do set month=%%i
for /f %%i in ('"powershell (Get-Date).ToString(\"yyyy\")"') do set year=%%i

Or, here is yesterday's date in yyyy-MM-dd format

for /f %%i in ('"powershell (Get-Date).AddDays(-1).ToString(\"yyyy-MM-dd\")"') do set yesterday=%%i

Day of the week

for /f %%d in ('"powershell (Get-Date).DayOfWeek"') do set DayOfWeek=%%d

Current time plus 15 minutes

for /f %%i in ('"powershell (Get-Date).AddMinutes(15).ToString(\"HH:mm\")"') do set time=%%i

From https://developer.mozilla.org/en-US/docs/Web/CSS/background-color

To set background color:

/* Hexadecimal value with color and 100% transparency*/
background-color: #11ffee00;  /* Fully transparent */

/* Special keyword values */
background-color: transparent;

/* HSL value with color and 100% transparency*/
background-color: hsla(50, 33%, 25%, 1.00);  /* 100% transparent */

/* RGB value with color and 100% transparency*/
background-color: rgba(117, 190, 218, 1.0);  /* 100% transparent */

you can use this function to get actionbar's height.

public int getActionBarHeight() {
    final TypedArray ta = getContext().getTheme().obtainStyledAttributes(
            new int[] {android.R.attr.actionBarSize});
    int actionBarHeight = (int) ta.getDimension(0, 0);
    return actionBarHeight;
}

A bat file has no structure...it is how you would type it on the command line. So just open your favourite editor..copy the line of code you want to run..and save the file as whatever.bat or whatever.cmd

Well here is a solution for you but I don't really understand why it works:

<html><body>
  <div style="width: 200px; border: 1px solid red;">Test</div>
  <div style="width: 200px; border: 1px solid blue; overflow: hidden; height: 1.5em;">My hovercraft is full of eels.  These pretzels are making me thirsty.</div>
  <div style="width: 200px; border: 1px solid yellow; overflow: hidden; height: 1.5em;">
  This_is_a_terrible_example_of_thinking_outside_the_box.
  </div>
  <table style="border: 2px solid black; border-collapse: collapse; width: 200px;"><tr>
   <td style="width:200px; border: 1px solid green; overflow: hidden; height: 1.5em;"><div style="width: 200px; border: 1px solid yellow; overflow: hidden;">
    This_is_a_terrible_example_of_thinking_outside_the_box.
   </div></td>
  </tr></table>
</body></html>

Namely, wrapping the cell contents in a div.

Use the tee command:

echo "hello" | tee logfile.txt

For gcc 4.8.4 you need to use -std=c++1y in later versions, looks like starting with 5.2 you can use -std=c++14.

If we look at the gcc online documents we can find the manuals for each version of gcc and we can see by going to Dialect options for 4.9.3 under the GCC 4.9.3 manual it says:

‘c++1y’

The next revision of the ISO C++ standard, tentatively planned for 2014. Support is highly experimental, and will almost certainly change in incompatible ways in future releases.

So up till 4.9.3 you had to use -std=c++1y while the gcc 5.2 options say:

‘c++14’ ‘c++1y’

The 2014 ISO C++ standard plus amendments. The name ‘c++1y’ is deprecated.

It is not clear to me why this is listed under Options Controlling C Dialect but that is how the documents are currently organized.

We had a very similar issue whereby a client's website was trying to connect to our Web API service and getting that same message. This started happening completely out of the blue when there had been no code changes or Windows updates on the server where IIS was running.

In our case it turned out that the calling website was using a version of .Net that only supported TLS 1.0 and for some reason the server where our IIS was running stopped appeared to have stopped accepting TLS 1.0 calls. To diagnose that we had to explicitly enable TLS via the registry on the IIS's server and then restart that server. These are the reg keys:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS
    1.0\Client] "DisabledByDefault"=dword:00000000 "Enabled"=dword:00000001

    [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS
    1.0\Server] "DisabledByDefault"=dword:00000000 "Enabled"=dword:00000001

    [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS
    1.1\Client] "DisabledByDefault"=dword:00000000 "Enabled"=dword:00000001

    [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS
    1.1\Server] "DisabledByDefault"=dword:00000000 "Enabled"=dword:00000001

    [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS
    1.2\Client] "DisabledByDefault"=dword:00000000 "Enabled"=dword:00000001

    [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS
    1.2\Server] "DisabledByDefault"=dword:00000000 "Enabled"=dword:00000001

If that doesn't do it, you could also experiment with adding the entry for SSL 2.0:


    [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\SSL 2.0\Client]
    "DisabledByDefault"=dword:00000000
    "Enabled"=dword:00000001

    [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\SSL 2.0\Server]
    "DisabledByDefault"=dword:00000000
    "Enabled"=dword:00000001

My answer to another question here has this powershell script that we used to add the entries:

NOTE: Enabling old security protocols is not a good idea, the right answer in our case was to get the client website to update it's code to use TLS 1.2, but the registry entries above can help diagnose the issue in the first place.

In Java, an initializer with the declaration means the field is always initialized the same way, regardless of which constructor is used (if you have more than one) or the parameters of your constructors (if they have arguments), although a constructor might subsequently change the value (if it is not final). So using an initializer with a declaration suggests to a reader that the initialized value is the value that the field has in all cases, regardless of which constructor is used and regardless of the parameters passed to any constructor. Therefore use an initializer with the declaration only if, and always if, the value for all constructed objects is the same.

I managed to do it with CSS display: table-*. I haven't tested with more than 3 blocks though.

If you want to use raw python rather than numpy or panda, you can use the python stats module to find the median of the upper and lower half of the list:

    >>> import statistics as stat
    >>> def quartile(data):
            data.sort()               
            half_list = int(len(data)//2)
            upper_quartile = stat.median(data[-half_list]
            lower_quartile = stat.median(data[:half_list])
            print("Lower Quartile: "+str(lower_quartile))
            print("Upper Quartile: "+str(upper_quartile))
            print("Interquartile Range: "+str(upper_quartile-lower_quartile)

    >>> quartile(df.time_diff)

Line 1: import the statistics module under the alias "stat"

Line 2: define the quartile function

Line 3: sort the data into ascending order

Line 4: get the length of half of the list

Line 5: get the median of the lower half of the list

Line 6: get the median of the upper half of the list

Line 7: print the lower quartile

Line 8: print the upper quartile

Line 9: print the interquartile range

Line 10: run the quartile function for the time_diff column of the DataFrame

It's also possible to use jQuery's .load()

$('#submitform').click(function() {
  $('#showresults').load('getinfo.asp #showresults', {
    txtsearch: $('#appendedInputButton').val()
  }, function() {
    // alert('Load was performed.')
    // $('#showresults').slideDown('slow')
  });
});

unlike $.get(), allows us to specify a portion of the remote document to be inserted. This is achieved with a special syntax for the url parameter. If one or more space characters are included in the string, the portion of the string following the first space is assumed to be a jQuery selector that determines the content to be loaded.

We could modify the example above to use only part of the document that is fetched:

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

When this method executes, it retrieves the content of ajax/test.html, but then jQuery parses the returned document to find the element with an ID of container. This element, along with its contents, is inserted into the element with an ID of result, and the rest of the retrieved document is discarded.
