I only use MicrosoftAdvertising.Mobile and Microsoft.Advertising.Mobile.UI and I am served ads. The SDK should only add the DLLs not reference itself.

Note: You need to explicitly set width and height Make sure the phone dialer, and web browser capabilities are enabled

Followup note: Make sure that after you've removed the SDK DLL, that the xmlns references are not still pointing to it. The best route to take here is

1. Remove the XAML for the ad
2. Remove the xmlns declaration (usually at the top of the page, but sometimes will be declared in the ad itself)
3. Remove the bad DLL (the one ending in .SDK )
4. Do a Clean and then Build (clean out anything remaining from the DLL)
5. Add the xmlns reference (actual reference is below)
6. Add the ad to the page (example below)

Here is the xmlns reference:

xmlns:AdNamepace="clr-namespace:Microsoft.Advertising.Mobile.UI;assembly=Microsoft.Advertising.Mobile.UI" 

Then the ad itself:

<AdNamespace:AdControl x:Name="myAd" Height="80" Width="480"                    AdUnitId="yourAdUnitIdHere" ApplicationId="yourIdHere"/> 

The Chapter object should have reference to the book it came from so I would suggest something like chapter.getBook().getTitle();

Your database table structure should have a books table and a chapters table with columns like:

books

• id
• book specific info
• etc

chapters

• id
• book_id
• chapter specific info
• etc

Then to reduce the number of queries use a join table in your search query.

Very interesting question.

I don't see any difference w.r.t safety or versatility, since you can do the same thing with pointer or reference. I also don't think there is any visible difference in performance since references are implemented by pointers.

But I think using reference is better because it is consistent with the standard library. For example, chaining in iostream is done by reference rather than pointer.

We have found that adding the Apptentive cocoa pod to an existing Xcode project may potentially not include some of our required frameworks.

Check your linker flags:

Target > Build Settings > Other Linker Flags 

You should see -lApptentiveConnect listed as a linker flag:

... -ObjC -lApptentiveConnect ... 

You should also see our required Frameworks listed:

• Accelerate
• CoreData
• CoreText
• CoreGraphics
• CoreTelephony
• Foundation
• QuartzCore
• StoreKit
• SystemConfiguration

• UIKit

  -ObjC -lApptentiveConnect -framework Accelerate -framework CoreData -framework CoreGraphics -framework CoreText -framework Foundation -framework QuartzCore -framework SystemConfiguration -framework UIKit -framework CoreTelephony -framework StoreKit  

So I assume your permissions table has a foreign key reference to admin_accounts table. If so because of referential integrity you will only be able to add permissions for account ids exsiting in the admin accounts table. Which also means that you wont be able to enter a user_account_id [assuming there are no duplicates!]

If you're creating a framework the whole idea is to make it portable. Tying a framework to the app delegate defeats the purpose of building a framework. What is it you need the app delegate for?

I've heard that you must set a variable to 'null' once you're done using it so the garbage collector can get to it (if it's a field var).

This is very rarely a good idea. You only need to do this if the variable is a reference to an object which is going to live much longer than the object it refers to.

Say you have an instance of Class A and it has a reference to an instance of Class B. Class B is very large and you don't need it for very long (a pretty rare situation) You might null out the reference to class B to allow it to be collected.

A better way to handle objects which don't live very long is to hold them in local variables. These are naturally cleaned up when they drop out of scope.

If I were to have a variable that I won't be referring to agaon, would removing the reference vars I'm using (and just using the numbers when needed) save memory?

You don't free the memory for a primitive until the object which contains it is cleaned up by the GC.

Would that take more space than just plugging '5' into the println method?

The JIT is smart enough to turn fields which don't change into constants.

Been looking into memory management, so please let me know, along with any other advice you have to offer about managing memory

Use a memory profiler instead of chasing down 4 bytes of memory. Something like 4 million bytes might be worth chasing if you have a smart phone. If you have a PC, I wouldn't both with 4 million bytes.

The link you gave does actually describe the differences, but it's buried at the bottom of the page:

Text files are files containing sequences of lines of text. Depending on the environment where the application runs, some special character conversion may occur in input/output operations in text mode to adapt them to a system-specific text file format. Although on some environments no conversions occur and both text files and binary files are treated the same way, using the appropriate mode improves portability.

The conversion could be to normalize \r\n to \n (or vice-versa), or maybe ignoring characters beyond 0x7F (a-la 'text mode' in FTP). Personally I'd open everything in binary-mode and use a good text-encoding library for dealing with text.

You can use Jquery's on method and listen for the scroll event.

maybe this will help you out:

What you show looks like a mesh warp. That would be straightforward using OpenGL, but "straightforward OpenGL" is like straightforward rocket science.

I wrote an iOS app for my company called Face Dancerthat's able to do 60 fps mesh warp animations of video from the built-in camera using OpenGL, but it was a lot of work. (It does funhouse mirror type changes to faces - think "fat booth" live, plus lots of other effects.)

All your exercise conditionals are separate and the else is only tied to the last if statement. Use else if to bind them all together in the way I believe you intend.

It is very inefficient to store all values in memory, so the objects are reused and loaded one at a time. See this other SO question for a good explanation. Summary:

[...] when looping through the Iterable value list, each Object instance is re-used, so it only keeps one instance around at a given time.

Use properties file. Here is a good start: http://www.mkyong.com/java/java-properties-file-examples/

You need to use get_serving_url from the Images API. As that page explains, you need to call create_gs_key() first to get the key to pass to the Images API.

First of all, Applets are designed to be run from within the context of a browser (or applet viewer), they're not really designed to be added into other containers.

Technically, you can add a applet to a frame like any other component, but personally, I wouldn't. The applet is expecting a lot more information to be available to it in order to allow it to work fully.

Instead, I would move all of the "application" content to a separate component, like a JPanel for example and simply move this between the applet or frame as required...

ps- You can use f.setLocationRelativeTo(null) to center the window on the screen ;)

Updated

You need to go back to basics. Unless you absolutely must have one, avoid applets until you understand the basics of Swing, case in point...

Within the constructor of GalzyTable2 you are doing...

JApplet app = new JApplet(); add(app); app.init(); app.start(); 

...Why are you adding another applet to an applet??

Case in point...

Within the main method, you are trying to add the instance of JFrame to itself...

f.getContentPane().add(f, button2); 

Instead, create yourself a class that extends from something like JPanel, add your UI logical to this, using compound components if required.

Then, add this panel to whatever top level container you need.

You need to use ScriptManager.RegisterStartupScript for Ajax.

protected void ButtonPP_Click(object sender, EventArgs e) {     if (radioBtnACO.SelectedIndex < 0)     {         string csname1 = "PopupScript";          var cstext1 = new StringBuilder();         cstext1.Append("alert('Please Select Criteria!')");          ScriptManager.RegisterStartupScript(this, GetType(), csname1,             cstext1.ToString(), true);     } } 

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

Just a wild guess: (not much to go on) but I have had similar problems when, for example, I was using the IIS rewrite module on my local machine (and it worked fine), but when I uploaded to a host that did not have that add-on module installed, I would get a 500 error with very little to go on - sounds similar. It drove me crazy trying to find it.

So make sure whatever options/addons that you might have and be using locally in IIS are also installed on the host.

Similarly, make sure you understand everything that is being referenced/used in your web.config - that is likely the problem area.

For solution just uncomment line 29:

**protected $namespace = 'App\\Http\\Controllers';**

in 'app\Providers\RouteServiceProvider.php' file.

just uncomment line 29

Developers who are using Xcode 11.5 and trying to install their app in iOS 13.6 device will also see this message. It's a very confusing message.

All you need to do is Download Device support files of iOS 13.6 from this link

filsv/iPhoneOSDeviceSupport

• Close Xcode

• Unzip and paste it in this location:

  /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/

• Reopen Xcode.

Now you can install the app on the iOS 13.6 device using Xcode 11.5.

Extensions without enough permission on chrome can cause these warnings, for example for React developer tools, check if the following procedure solves your problem:

1. Right click on the extension icon.

Or

1. Go to extensions.
2. Click the three-dot in the row of React developer tool.

Then choose "this can read and write site data". You should see 3 options in the list, pick one that is strict enough based on how much you trust the extension and also satisfies the extensions's needs.

Try to see if it works in Incognito Mode. If it does, then it's a bug in recent Chrome. On my computer the following fix worked:

1. Quit Chrome
2. Delete your full Chrome cache folder
3. Restart Chrome

Goto You Chrome setting->About Chorme->Check version and download chromedriver from Below according your chrome Version https://chromedriver.chromium.org/downloads

Originally from https://stackoverflow.com/a/59796324/32453 though this might be useful:

Beware that your parent pom can (re) define repositories as well, and if it has overridden central and specified http for whatever reason, you'll need to fix that (so places to fix: ~/.m2/settings.xml AND also parent poms).

If you can't fix it in parent pom, you can override parent pom's repo's, like this, in your child pom (extracted from the 3.6.3 default super pom, seems they changed the name from repo1 as well):

  <repositories>
    <repository>
      <id>central</id>
      <name>Central Repository</name>
      <url>https://repo.maven.apache.org/maven2</url> <!-- the https you've been looking for -->
      <layout>default</layout>
      <snapshots>
        <enabled>false</enabled> <!-- or set to true if desired, default is false -->
      </snapshots>
    </repository>
  </repositories>

I add the following code to my pom.xml file. It solved my problem.

<properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <maven.compiler.source>1.8</maven.compiler.source>
    <maven.compiler.target>1.8</maven.compiler.target>
</properties>

This happens because $cOTLdata is not null but the index 'char_data' does not exist. Previous versions of PHP may have been less strict on such mistakes and silently swallowed the error / notice while 7.4 does not do this anymore.

To check whether the index exists or not you can use isset():

isset($cOTLdata['char_data'])

Which means the line should look something like this:

$len = isset($cOTLdata['char_data']) ? count($cOTLdata['char_data']) : 0;

Note I switched the then and else cases of the ternary operator since === null is essentially what isset already does (but in the positive case).

I had same problem & i have installed "create-react-app" globally on my machine. There is error :

"A template was not provided. This is likely because you're using an outdated version of create-react-app. Please note that global installs of create-react-app are no longer supported."

Then i removed previous install by using this command.

npm uninstall -g create-react-app

Then install new react app.

npx create-react-app new-app

For anyone going through these issues and uneasy about disabling a whole set of checks, there is a way to pass your own custom signatures to Intelephense.

Copied from Intelephese repo's comment (by @KapitanOczywisty):
https://github.com/bmewburn/vscode-intelephense/issues/892#issuecomment-565852100

For single workspace it is very simple, you have to create .php file with all signatures and intelephense will index them.

If you want add stubs globally, you still can, but I'm not sure if it's intended feature. Even if intelephense.stubs throws warning about incorrect value you can in fact put there any folder name.

{   
   "intelephense.stubs": [
       // ...
       "/path/to/your/stub"   
   ] 
} 

Note: stubs are refreshed with this setting change.

You can take a look at build-in stubs here: https://github.com/JetBrains/phpstorm-stubs

In my case, I needed dspec's describe, beforeEach, it... to don't be highlighted as errors, so I just included the file with the signatures /directories_and_paths/app/vendor/bin/dspec in my VSCode's workspace settings, which had the function declarations I needed:

function describe($description = null, \Closure $closure = null) {
}

function it($description, \Closure $closure) {
}

// ... and so on

A simple brew update && brew upgrade did the trick for me

By default nginx limits upload size to 1MB.

With client_max_body_size you can set your own limit, as in

location /uploads {
    ...
    client_max_body_size 100M;
} 

You can set this setting also on the http or server block instead (See here).

This fixed my issue with net::ERR_HTTP2_PROTOCOL_ERROR

Just add .pack between the name and the extension in the <script> tag in src. i.e.:

<script src="name.pack.js">
// code here
</script>

As the new feature comes, SameSite=None cookies must also be marked as Secure or they will be rejected.

One can find more information about the change on chromium updates and on this blog post

Note: not quite related directly to the question, but might be useful for others who landed here as it was my concern at first during development of my website:

if you are seeing the warning from question that lists some 3rd party sites (in my case it was google.com, huh) - that means they need to fix it and it's nothing to do with your site. Of course unless the warning mentions your site, in which case adding Secure should fix it.

You need to add the package containing the executable pg_config.

A prior answer should have details you need: pg_config executable not found

You can also use Python to press the arrow keys. I added a little bit of randomness in the following code as well.

from pyautogui import press, typewrite, hotkey
import time
from random import shuffle

array = ["left", "right", "up", "down"]

while True:
    shuffle(array)
    time.sleep(10)
    press(array[0])
    press(array[1])
    press(array[2])
    press(array[3])

When using Object.keys, the following works:

Object.keys(this)
    .forEach(key => {
      console.log(this[key as keyof MyClass]);
    });

I was having this problem after I installed the dotnet-ef tool using Ansible with sudo escalated previllage on Ubuntu. I had to add become: no for the Playbook task, then the dotnet-ef tool became available to the current user.

  - name: install dotnet tool dotnet-ef
    command: dotnet tool install --global dotnet-ef --version {{dotnetef_version}}
    become: no

UPDATE:

To append Token to each request you can create one Interceptor as below.

import { Injectable } from '@angular/core';
import { HttpEvent, HttpHandler, HttpInterceptor, HttpRequest } from '@angular/common/http';
import { Observable } from 'rxjs';

@Injectable()
export class AuthInterceptor implements HttpInterceptor {

  intercept(req: HttpRequest<any>, next: HttpHandler): Observable<HttpEvent<any>> {
    const token = window.localStorage.getItem('tokenKey'); // you probably want to store it in localStorage or something


    if (!token) {
      return next.handle(req);
    }

    const req1 = req.clone({
      headers: req.headers.set('Authorization', `${token}`),
    });

    return next.handle(req1);
  }

}

Example

Here's my version of fix in ObjectiveC using Categories. With this approach you'll have default UIModalPresentationStyleFullScreen behaviour until another one explicitly set.

#import "UIViewController+Presentation.h"
#import "objc/runtime.h"

@implementation UIViewController (Presentation)

- (void)setModalPresentationStyle:(UIModalPresentationStyle)modalPresentationStyle {
    [self setPrivateModalPresentationStyle:modalPresentationStyle];
}

-(UIModalPresentationStyle)modalPresentationStyle {
    UIModalPresentationStyle style = [self privateModalPresentationStyle];
    if (style == NSNotFound) {
        return UIModalPresentationFullScreen;
    }
    return style;
}

- (void)setPrivateModalPresentationStyle:(UIModalPresentationStyle)modalPresentationStyle {
    NSNumber *styleNumber = [NSNumber numberWithInteger:modalPresentationStyle];
     objc_setAssociatedObject(self, @selector(privateModalPresentationStyle), styleNumber, OBJC_ASSOCIATION_RETAIN_NONATOMIC);
}

- (UIModalPresentationStyle)privateModalPresentationStyle {
    NSNumber *styleNumber = objc_getAssociatedObject(self, @selector(privateModalPresentationStyle));
    if (styleNumber == nil) {
        return NSNotFound;
    }
    return styleNumber.integerValue;
}

@end

The solution needs to add these headers to the server response.

'Access-Control-Allow-Origin', '*'
'Access-Control-Allow-Methods', 'GET,POST,OPTIONS,DELETE,PUT'

If you have access to the server, you can add them and this will solve your problem

You can try concatentaing this in front of the url:

I have tried a lot of suggestions to fix this problem for an existing project on my Windows 10 machine and ended up following these steps to fix it;

• Uninstall Node.js from "Add or remove programs". Fire up a new Command prompt and type gulp -v and then node -v to check that it has been uninstalled completely.
• Download and install Node.js v10.16.0 - not the latest as latest node & gulp combination is causing the problem as far as I see. During installation I didn't change the installation path which I normally do(C:\Program Files\nodejs).
• Open up a new Command prompt, go to your project's directory where you have got your gulpfile.js and start gulp as shown in the image.

Please note sometimes when I switch between git branches I might need to close my Visual Studio and run it as Admin again in order to see this solution working again.

As far as I see this problem started to happen after I installed the latest recommended version(12.18.4) of Node.js for a new project and I only realised this when some FE changes weren't reflected on the existing web project.

I just used allow_pickle = True as an argument to np.load() and it worked for me.

np.load(path, allow_pickle=True)

I used tensorflow 1.8 to train my model and there is no problem for now. Tensorflow 2.0 alpha is not suitable with object detection API

Actually the warnings are very useful when you develop with hooks. but in some cases, it can needle you. especially when you do not need to listen for dependencies change.

If you don't want to put fetchBusinesses inside the hook's dependencies, you can simply pass it as an argument to the hook's callback and set the main fetchBusinesses as the default value for it like this

useEffect((fetchBusinesses = fetchBusinesses) => {
   fetchBusinesses();
}, []);

It's not best practice but it could be useful in some cases.

Also as Shubnam wrote, you can add below code to tell ESLint to ignore the checking for your hook.

// eslint-disable-next-line react-hooks/exhaustive-deps

Yes it's possible. Follow these steps:

1. Download Xcode 10.2 via this link (you need to be signed in with your Apple Id): https://developer.apple.com/services-account/download?path=/Developer_Tools/Xcode_10.2/Xcode_10.2.xip and install it
2. Edit Xcode.app/Contents/Info.plist and change the Minimum System Version to 10.13.6
3. Do the same for Xcode.app/Contents/Developer/Applications/Simulator.app/Contents/Info.plist (might require a restart of Xcode and/or Mac OS to make it open the simulator on run)
4. Replace Xcode.app/Contents/Developer/usr/bin/xcodebuild with the one from 10.1 (or another version you have currently installed, such as 10.0).
5. If there are problems with the simulator, reboot your Mac

After hours searching for a answer. The solution was to make a downgrade node to version 12.4.

In my case I realize that the error just occurs in version react native 0.60 with node version 12.6.

I know this is not the solution to OPs post. However, this post is the first one indexed by Google when I searched for answers to this error. For this reason I feel this will benefit others.

The following error...

The POST method is not supported for this route. Supported methods: GET, HEAD.

was caused by not clearing the routing cache

php artisan route:cache

Old ionic cli (4.2) was causing issue in my case, update to 5 solve the problem

If your are come from react-native and facing this error just do this

1. Open Podfile(your project > ios>Podfile)
2. comment flipper functions in podfile as below

#use_flipper!
 #post_install do |installer|
   #flipper_post_install(installer)
 #end

3. In terminal inside IOS folder enter this command pod install

yep, that is it hope it works to you

The following steps can be used:

sudo apt-get -y update

i also got same error , i just change the java version in pom.xml from 11 to 1.8 and it's work fine.

P.S:

• I have been using vs code for a while now and found an another way to show virtual environments in vs code.

• Go to the parent folder in which venv is there through command prompt.

• Type code . and Enter. [Working on both windows and linux for me.]

• That should also show the virtual environments present in that folder.

Original Answer

I almost run into same problem everytime I am working on VS-Code using venv. I follow below steps, hope it helps:

1. Go to File > preferences > Settings.

2. Click on Workspace settings.

3. Under Files:Association, in the JSON: Schemas section, you will find Edit in settings.json , click on that.

4. Update "python.pythonPath": "Your_venv_path/bin/python" under workspace settings. (For Windows): Update "python.pythonPath": "Your_venv_path/Scripts/python.exe" under workspace settings.

5. Restart VSCode incase if it still doesn't show your venv.

Just add this git config --global http.sslVerify false , so that it doesn't check the certificate and it should work just fine

I had a similar issue thanks @ford04 helped me out.

However, another error occurred.

NB. I am using ReactJS hooks

ndex.js:1 Warning: Cannot update during an existing state transition (such as within `render`). Render methods should be a pure function of props and state.

What causes the error?

import {useHistory} from 'react-router-dom'

const History = useHistory()
if (true) {
  history.push('/new-route');
}
return (
  <>
    <render component />
  </>
)

This could not work because despite you are redirecting to new page all state and props are being manipulated on the dom or simply rendering to the previous page did not stop.

What solution I found

import {Redirect} from 'react-router-dom'

if (true) {
  return <redirect to="/new-route" />
}
return (
  <>
    <render component />
  </>
)

In case of a Pylint error, install the following

pipenv install pylint-django

Then create a file, .pylintrc, in the root folder and write the following

load-plugins=pylint-django

In order to downgrade, i had to recompile from source (MacOS Mojave)

$ wget https://ssl.icu-project.org/files/icu4c/62.1/icu4c-62_1-src.tgz
$ tar xvfz icu4c-62_1-src.tgz
$ cd icu/sources
$ ./configure
$ make
$ make install

To expand on Ryan's answer:

Whenever setStateValues is called, React re-renders your component, which means that the function body of the StateSelector component function gets re-executed.

React docs:

setState() will always lead to a re-render unless shouldComponentUpdate() returns false.

Essentially, you're setting state with:

setStateValues(allowedState);

causing a re-render, which then causes the function to execute, and so on. Hence, the loop issue.

To illustrate the point, if you set a timeout as like:

  setTimeout(
    () => setStateValues(allowedState),
    1000
  )

Which ends the 'too many re-renders' issue.

In your case, you're dealing with a side-effect, which is handled with UseEffectin your component functions. You can read more about it here.

For me, everything was just fine but the issue was due to publishing by different VS versions, weird !!! (latest VS 2019 (16.4.2)). When I publish the application with VS 2017 it works fine.

The actual issue is in its dependency json file (e.g. MyWebApp.deps.json) in the publish folder. Hope it helps someone.

This problem is probably from your /etc/apt/sources.list as others mentioned but there is chance that the problem is with your hard disk. I solved the same issue by cleaning up some space.

When you don't have enough space on your hard disk, updating your machine won't occur until you delete some files.

I solved this issue after changing the "Gradle Version" and "Android Plugin version".

You just goto "File>>Project Structure>>Project>>" and make changes here. I have worked a combination of versions from another working project of mine and added to the Project where I was getting this problem.

This post will go through the following topics:

• how to correctly generalize to multiple DataFrames (and why merge has shortcomings here)
• merging on unique keys
• merging on non-unqiue keys

_{BACK TO TOP}

Generalizing to multiple DataFrames

Oftentimes, the situation arises when multiple DataFrames are to be merged together. Naively, this can be done by chaining merge calls:

df1.merge(df2, ...).merge(df3, ...)

However, this quickly gets out of hand for many DataFrames. Furthermore, it may be necessary to generalise for an unknown number of DataFrames.

Here I introduce pd.concat for multi-way joins on unique keys, and DataFrame.join for multi-way joins on non-unique keys. First, the setup.

# Setup.
np.random.seed(0)
A = pd.DataFrame({'key': ['A', 'B', 'C', 'D'], 'valueA': np.random.randn(4)})    
B = pd.DataFrame({'key': ['B', 'D', 'E', 'F'], 'valueB': np.random.randn(4)})
C = pd.DataFrame({'key': ['D', 'E', 'J', 'C'], 'valueC': np.ones(4)})
dfs = [A, B, C] 

# Note, the "key" column values are unique, so the index is unique.
A2 = A.set_index('key')
B2 = B.set_index('key')
C2 = C.set_index('key')

dfs2 = [A2, B2, C2]

Multiway merge on unique keys

If your keys (here, the key could either be a column or an index) are unique, then you can use pd.concat. Note that pd.concat joins DataFrames on the index.

# merge on `key` column, you'll need to set the index before concatenating
pd.concat([
    df.set_index('key') for df in dfs], axis=1, join='inner'
).reset_index()

  key    valueA    valueB  valueC
0   D  2.240893 -0.977278     1.0

# merge on `key` index
pd.concat(dfs2, axis=1, sort=False, join='inner')

       valueA    valueB  valueC
key                            
D    2.240893 -0.977278     1.0

Omit join='inner' for a FULL OUTER JOIN. Note that you cannot specify LEFT or RIGHT OUTER joins (if you need these, use join, described below).

Multiway merge on keys with duplicates

concat is fast, but has its shortcomings. It cannot handle duplicates.

A3 = pd.DataFrame({'key': ['A', 'B', 'C', 'D', 'D'], 'valueA': np.random.randn(5)})

pd.concat([df.set_index('key') for df in [A3, B, C]], axis=1, join='inner')
ValueError: Shape of passed values is (3, 4), indices imply (3, 2)

In this situation, we can use join since it can handle non-unique keys (note that join joins DataFrames on their index; it calls merge under the hood and does a LEFT OUTER JOIN unless otherwise specified).

# join on `key` column, set as the index first
# For inner join. For left join, omit the "how" argument.
A.set_index('key').join(
    [df.set_index('key') for df in (B, C)], how='inner').reset_index()

  key    valueA    valueB  valueC
0   D  2.240893 -0.977278     1.0

# join on `key` index
A3.set_index('key').join([B2, C2], how='inner')

       valueA    valueB  valueC
key                            
D    1.454274 -0.977278     1.0
D    0.761038 -0.977278     1.0

It's the "null coalescing operator", added in php 7.0. The definition of how it works is:

It returns its first operand if it exists and is not NULL; otherwise it returns its second operand.

So it's actually just isset() in a handy operator.

Those two are equivalent¹:

$foo = $bar ?? 'something';
$foo = isset($bar) ? $bar : 'something';

EDIT: As this answer gets a lot of views, little clarification:

¹There is a difference: In case of ??, the first expression is evaluated only once, as opposed to ? :, where the expression is first evaluated in the condition section, then the second time in the "answer" section.

I am using git+vscode+windows+vue, and after read the eslint document: https://eslint.org/docs/rules/linebreak-style

Finally fix it by:

add *.js text eol=lf to .gitattributes

then run vue-cli-service lint --fix

Using .multiply() (ufunc multiply)

a_1 = np.array([1.0, 2.0, 3.0])
a_2 = np.array([[1., 2.], [3., 4.]])
b = 2.0 

np.multiply(a_1,b)
# array([2., 4., 6.])
np.multiply(a_2,b)
# array([[2., 4.],[6., 8.]])

For really simple prop comparison you can use useEffect to easily check to see if a prop has updated.

const myComponent = ({ prop }) => {
  useEffect(() => {
    ---Do stuffhere----
  }, [prop])
}

useEffect will then only run your code if the prop changes.

I suggest to look at Dan Abramov (one of the React core maintainers) answer here:

I think you're making it more complicated than it needs to be.

function Example() {
  const [data, dataSet] = useState<any>(null)

  useEffect(() => {
    async function fetchMyAPI() {
      let response = await fetch('api/data')
      response = await response.json()
      dataSet(response)
    }

    fetchMyAPI()
  }, [])

  return <div>{JSON.stringify(data)}</div>
}

Longer term we'll discourage this pattern because it encourages race conditions. Such as — anything could happen between your call starts and ends, and you could have gotten new props. Instead, we'll recommend Suspense for data fetching which will look more like

const response = MyAPIResource.read();

and no effects. But in the meantime you can move the async stuff to a separate function and call it.

You can read more about experimental suspense here.

If you want to use functions outside with eslint.

 function OutsideUsageExample() {
  const [data, dataSet] = useState<any>(null)

  const fetchMyAPI = useCallback(async () => {
    let response = await fetch('api/data')
    response = await response.json()
    dataSet(response)
  }, [])

  useEffect(() => {
    fetchMyAPI()
  }, [fetchMyAPI])

  return (
    <div>
      <div>data: {JSON.stringify(data)}</div>
      <div>
        <button onClick={fetchMyAPI}>manual fetch</button>
      </div>
    </div>
  )
}

If you will use useCallback, look at example of how it works useCallback. Sandbox.

import React, { useState, useEffect, useCallback } from "react";

export default function App() {
  const [counter, setCounter] = useState(1);

  // if counter is changed, than fn will be updated with new counter value
  const fn = useCallback(() => {
    setCounter(counter + 1);
  }, [counter]);

  // if counter is changed, than fn will not be updated and counter will be always 1 inside fn
  /*const fnBad = useCallback(() => {
      setCounter(counter + 1);
    }, []);*/

  // if fn or counter is changed, than useEffect will rerun
  useEffect(() => {
    if (!(counter % 2)) return; // this will stop the loop if counter is not even

    fn();
  }, [fn, counter]);

  // this will be infinite loop because fn is always changing with new counter value
  /*useEffect(() => {
    fn();
  }, [fn]);*/

  return (
    <div>
      <div>Counter is {counter}</div>
      <button onClick={fn}>add +1 count</button>
    </div>
  );
}

For a non-angular general answer for those who land on this question from Google:

Every time you face this error its probably because of a memory leak or difference between how Node <= 10 and Node > 10 manage memory. Usually just increasing the memory allocated to Node will allow your program to run but may not actually solve the real problem and the memory used by the node process could still exceed the new memory you allocate. I'd advise profiling memory usage in your node process when it starts running or updating to node > 10.

I had a memory leak. Here is a great article on debugging memory leaks in node.

That said, to increase the memory, in the terminal where you run your Node process:

export NODE_OPTIONS="--max-old-space-size=8192"

where values of max-old-space-size can be: [2048, 4096, 8192, 16384] etc

[UPDATE] More examples for further clarity:

export NODE_OPTIONS="--max-old-space-size=5120" #increase to 5gb
export NODE_OPTIONS="--max-old-space-size=6144" #increase to 6gb
export NODE_OPTIONS="--max-old-space-size=7168" #increase to 7gb
export NODE_OPTIONS="--max-old-space-size=8192" #increase to 8gb

# and so on...

# formula:
export NODE_OPTIONS="--max-old-space-size=(X * 1024)" #increase to Xgb

# Note: it doesn't have to be multiples of 1024. 
# max-old-space-size can be any number of memory megabytes(MB) you have available.

I believe the original post was about removing the space between the buttons in a row, not adding space.

The trick is that the minimum space between the buttons was due to padding built into the buttons as part of the material design specification.

So, don't use buttons! But a GestureDetector instead. This widget type give the onClick / onTap functionality but without the styling.

See this post for an example.

Basically we had to enable TLS 1.2 for .NET 4.x. Making this registry changed worked for me, and stopped the event log filling up with the Schannel error.

More information on the answer can be found here

Linked Info Summary

Enable TLS 1.2 at the system (SCHANNEL) level:

Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.2]
[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

(equivalent keys are probably also available for other TLS versions)

Tell .NET Framework to use the system TLS versions:

Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\v4.0.30319]
"SystemDefaultTlsVersions"=dword:00000001
[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\.NETFramework\v4.0.30319]
"SystemDefaultTlsVersions"=dword:00000001

This may not be desirable for edge cases where .NET Framework 4.x applications need to have different protocols enabled and disabled than the OS does.

I like to define a mount function, it tricks EsLint in the same way useMount does and I find it more self-explanatory.

const mount = () => {
  console.log('mounted')
  // ...

  const unmount = () => {
    console.log('unmounted')
    // ...
  }
  return unmount
}
useEffect(mount, [])

You can easily do this one. In each column you will get a class with the field name prefixed with mat-column, so the class will be like mat-column-yourFieldName. So for that you can set the style like following

.mat-column-yourFieldName {
    flex: none;
    width: 100px;
}

So we can give fixed width for column as per our requirement.

Hope this helps for someone.

When you call "https://darkorbit.com/" your server figures that it's missing "www" so it redirects the call to "http://www.darkorbit.com/" and then to "https://www.darkorbit.com/", your WebView call is blocked at the first redirection as it's a "http" call. You can call "https://www.darkorbit.com/" instead and it will solve the issue.

Note: These solutions work for various versions of Java including Java 8, Java 11, and the new Java 15, and for any other previous Java version covered by the listed version managers. This includes alternative JDK's from OpenJDK, Oracle, IBM, Azul, Amazon Correto, Graal and more. Easily work with Java 7, Java 8, Java 9, Java 10, Java 11, Java 12, Java 13, Java 14, and Java 15!

You have a few options for how to do the installation as well as manage JDK switching. Installation can be done by Homebrew, SDKMAN, Jabba, or a manual install. Switching can be done by JEnv, SDKMAN, Jabba, or manually by setting JAVA_HOME. All of these are described below.

Installation

First, install Java using whatever method you prefer including Homebrew, SDKMAN or a manual install of the tar.gz file. The advantage of a manual install is that the location of the JDK can be placed in a standardized location for Mac OSX. Otherwise, there are easier options such as SDKMAN that also will install other important and common tools for the JVM.

Installing and Switching versions with SDKMAN

SDKMAN is a bit different and handles both the install and the switching. SDKMAN also places the installed JDK's into its own directory tree, which is typically ~/.sdkman/candidates/java. SDKMAN allows setting a global default version, and a version specific to the current shell.

1. Install SDKMAN from https://sdkman.io/install

2. List the Java versions available to make sure you know the version ID

   sdk list java
   

3. Install one of those versions, for example, Java 15:

   sdk install java 15-open 
   

4. Make 15 the default version:

   sdk default java 15-open
   

   Or switch to 15 for the session:

   sdk use java 15-open
   

When you list available versions for installation using the list command, you will see a wide variety of distributions of Java:

sdk list java

And install additional versions, such as JDK 8:

sdk install java 8.0.181-oracle

SDKMAN can work with previously installed existing versions. Just do a local install giving your own version label and the location of the JDK:

sdk install java my-local-13 /Library/Java/JavaVirtualMachines/jdk-13.jdk/Contents/Home

And use it freely:

sdk use java my-local-13

More information is available in the SDKMAN Usage Guide along with other SDK's it can install and manage.

SDKMAN will automatically manage your PATH and JAVA_HOME for you as you change versions.

Install manually from OpenJDK download page:

1. Download OpenJDK for Mac OSX from http://jdk.java.net/ (for example Java 15)

2. Unarchive the OpenJDK tar, and place the resulting folder (i.e. jdk-15.jdk) into your /Library/Java/JavaVirtualMachines/ folder since this is the standard and expected location of JDK installs. You can also install anywhere you want in reality.

Install with Homebrew

The version of Java available in Homebrew Cask previous to October 3, 2018 was indeed the Oracle JVM. Now, however, it has now been updated to OpenJDK. Be sure to update Homebrew and then you will see the lastest version available for install.

1. install Homebrew if you haven't already. Make sure it is updated:

    brew update
   

2. Add the casks tap, if you want to use the AdoptOpenJDK versions (which tend to be more current):

    brew tap adoptopenjdk/openjdk
   

   These casks change their Java versions often, and there might be other taps out there with additional Java versions.

3. Look for installable versions:

    brew search java   
   

   or for AdoptOpenJDK versions:

    brew search jdk     
   

4. Check the details on the version that will be installed:

    brew info java
   

   or for the AdoptOpenJDK version:

    brew info adoptopenjdk
   

5. Install a specific version of the JDK such as java11, adoptopenjdk8, or adoptopenjdk13, or just java or adoptopenjdk for the most current of that distribution. For example:

    brew install java
   
    brew cask install adoptopenjdk13
   

And these will be installed into /Library/Java/JavaVirtualMachines/ which is the traditional location expected on Mac OSX.

Other installation options:

Some other flavours of OpenJDK are:

Azul Systems Java Zulu certified builds of OpenJDK can be installed by following the instructions on their site.

Zulu® is a certified build of OpenJDK that is fully compliant with the Java SE standard. Zulu is 100% open source and freely downloadable. Now Java developers, system administrators, and end-users can enjoy the full benefits of open source Java with deployment flexibility and control over upgrade timing.

Amazon Correto OpenJDK builds have an easy to use an installation package for Java 8 or Java 11, and installs to the standard /Library/Java/JavaVirtualMachines/ directory on Mac OSX.

Amazon Corretto is a no-cost, multiplatform, production-ready distribution of the Open Java Development Kit (OpenJDK). Corretto comes with long-term support that will include performance enhancements and security fixes. Amazon runs Corretto internally on thousands of production services and Corretto is certified as compatible with the Java SE standard. With Corretto, you can develop and run Java applications on popular operating systems, including Linux, Windows, and macOS.

Where is my JDK?!?!

To find locations of previously installed Java JDK's installed at the default system locations, use:

/usr/libexec/java_home -V

15, x86_64: "OpenJDK 15" /Library/Java/JavaVirtualMachines/jdk-15.jdk/Contents/Home 14, x86_64: "OpenJDK 14" /Library/Java/JavaVirtualMachines/jdk-14.jdk/Contents/Home 13, x86_64: "OpenJDK 13" /Library/Java/JavaVirtualMachines/openjdk-13.jdk/Contents/Home 12, x86_64: "OpenJDK 12" /Library/Java/JavaVirtualMachines/jdk-12.jdk/Contents/Home
11, x86_64: "Java SE 11" /Library/Java/JavaVirtualMachines/jdk-11.jdk/Contents/Home
10.0.2, x86_64: "Java SE 10.0.2" /Library/Java/JavaVirtualMachines/jdk-10.0.2.jdk/Contents/Home
9, x86_64: "Java SE 9" /Library/Java/JavaVirtualMachines/jdk-9.jdk/Contents/Home
1.8.0_144, x86_64: "Java SE 8" /Library/Java/JavaVirtualMachines/jdk1.8.0_144.jdk/Contents/Home

You can also report just the location of a specific Java version using -v. For example for Java 15:

/usr/libexec/java_home -v 15

/Library/Java/JavaVirtualMachines/jdk-15.jdk/Contents/Home

Knowing the location of the installed JDK's is also useful when using tools like JEnv, or adding a local install to SDKMAN, or linking a system JDK in Jabba -- and you need to know where to find them.

If you need to find JDK's installed by other tools, check these locations:

• SDKMAN installs to ~/.sdkman/candidates/java/
• Jabba installs to ~/.jabba/jdk

Switching versions manually

The Java executable is a wrapper that will use whatever JDK is configured in JAVA_HOME, so you can change that to also change which JDK is in use.

For example, if you installed or untar'd JDK 15 to /Library/Java/JavaVirtualMachines/jdk-15.jdk if it is the highest version number it should already be the default, if not you could simply set:

export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk-15.jdk/Contents/Home

And now whatever Java executable is in the path will see this and use the correct JDK.

Using the /usr/libexec/java_home utility as previously described helps you to create aliases or to run commands to change Java versions by identifying the locations of different JDK installations. For example, creating shell aliases in your .profile or .bash_profile to change JAVA_HOME for you:

export JAVA_8_HOME=$(/usr/libexec/java_home -v1.8)
export JAVA_9_HOME=$(/usr/libexec/java_home -v9)
export JAVA_10_HOME=$(/usr/libexec/java_home -v10)
export JAVA_11_HOME=$(/usr/libexec/java_home -v11)
export JAVA_12_HOME=$(/usr/libexec/java_home -v12)
export JAVA_13_HOME=$(/usr/libexec/java_home -v13)
export JAVA_14_HOME=$(/usr/libexec/java_home -v14)
export JAVA_15_HOME=$(/usr/libexec/java_home -v15)

alias java8='export JAVA_HOME=$JAVA_8_HOME'
alias java9='export JAVA_HOME=$JAVA_9_HOME'
alias java10='export JAVA_HOME=$JAVA_10_HOME'
alias java11='export JAVA_HOME=$JAVA_11_HOME'
alias java12='export JAVA_HOME=$JAVA_12_HOME'
alias java13='export JAVA_HOME=$JAVA_13_HOME'
alias java14='export JAVA_HOME=$JAVA_14_HOME'
alias java15='export JAVA_HOME=$JAVA_15_HOME'

# default to Java 15
java15

Then to change versions, just use the alias.

java8
java -version

java version "1.8.0_144"

Of course, setting JAVA_HOME manually works too!

Switching versions with JEnv

JEnv expects the Java JDK's to already exist on the machine and can be in any location. Typically you will find installed Java JDK's in /Library/Java/JavaVirtualMachines/. JEnv allows setting the global version of Java, one for the current shell, and a per-directory local version which is handy when some projects require different versions than others.

1. Install JEnv if you haven't already, instructions on the site http://www.jenv.be/ for manual install or using Homebrew.

2. Add any Java version to JEnv (adjust the directory if you placed this elsewhere):

   jenv add /Library/Java/JavaVirtualMachines/jdk-15.jdk/Contents/Home
   

3. Set your global version using this command:

   jenv global 15
   

You can also add other existing versions using jenv add in a similar manner, and list those that are available. For example Java 8:

jenv add /Library/Java/JavaVirtualMachines/jdk1.8.0_144.jdk/Contents/Home 
jenv versions

See the JEnv docs for more commands. You may now switch between any Java versions (Oracle, OpenJDK, other) at any time either for the whole system, for shells, or per local directory.

To help manage JAVA_HOME while using JEnv you can add the export plugin to do this for you.

$ jenv enable-plugin export
  You may restart your session to activate jenv export plugin echo export plugin activated

The export plugin may not adjust JAVA_HOME if it is already set, so you may need to clear this variable in your profile so that it can be managed by JEnv.

You can also use jenv exec <command> <parms...> to run single commands with JAVA_HOME and PATH set correctly for that one command, which could include opening another shell.

Installing and Switching versions with Jabba

Jabba also handles both the install and the switching. Jabba also places the installed JDK's into its own directory tree, which is typically ~/.jabba/jdk.

1. Install Jabba by following the instructions on the home page.

2. List available JDK's

   jabba ls-remote

3. Install Java JDK 12

   jabba install [email protected]

4. Use it:

   jabba use [email protected]

You can also alias version names, link to existing JDK's already installed, and find a mix of interesting JDK's such as GraalVM, Adopt JDK, IBM JDK, and more. The complete usage guide is available on the home page as well.

Jabba will automatically manage your PATH and JAVA_HOME for you as you change versions.

Use the Chocolatey packet manager. It's a command-line tool similar to npm. Once you have installed it, use

choco install openjdk

in an elevated command prompt to install OpenJDK.

To update an installed version to the latest version, type

choco upgrade openjdk

Pretty simple to use and especially helpful to upgrade to the latest version. No manual fiddling with path environment variables.

Now it is possible to install openjdk-11 this way:

sudo apt-get install openjdk-11-jdk

(Previously it installed openjdk-10, but not anymore)

According to the release-notes, Java 11 removed the Java EE modules:

java.xml.bind (JAXB) - REMOVED

• Java 8 - OK
• Java 9 - DEPRECATED
• Java 10 - DEPRECATED
• Java 11 - REMOVED

See JEP 320 for more info.

You can fix the issue by using alternate versions of the Java EE technologies. Simply add Maven dependencies that contain the classes you need:

<dependency>
  <groupId>javax.xml.bind</groupId>
  <artifactId>jaxb-api</artifactId>
  <version>2.3.0</version>
</dependency>
<dependency>
  <groupId>com.sun.xml.bind</groupId>
  <artifactId>jaxb-core</artifactId>
  <version>2.3.0</version>
</dependency>
<dependency>
  <groupId>com.sun.xml.bind</groupId>
  <artifactId>jaxb-impl</artifactId>
  <version>2.3.0</version>
</dependency>

Jakarta EE 8 update (Mar 2020)

Instead of using old JAXB modules you can fix the issue by using Jakarta XML Binding from Jakarta EE 8:

<dependency>
  <groupId>jakarta.xml.bind</groupId>
  <artifactId>jakarta.xml.bind-api</artifactId>
  <version>2.3.3</version>
</dependency>
<dependency>
  <groupId>com.sun.xml.bind</groupId>
  <artifactId>jaxb-impl</artifactId>
  <version>2.3.3</version>
  <scope>runtime</scope>
</dependency>

Jakarta EE 9 update (Nov 2020)

Use latest release of Eclipse Implementation of JAXB 3.0.0:

• Jakarta EE9 API jakarta.xml.bind-api
• compatible implementation jaxb-impl

<dependency>
  <groupId>jakarta.xml.bind</groupId>
  <artifactId>jakarta.xml.bind-api</artifactId>
  <version>3.0.0</version>
</dependency>
<dependency>
  <groupId>com.sun.xml.bind</groupId>
  <artifactId>jaxb-impl</artifactId>
  <version>3.0.0</version>
  <scope>runtime</scope>
</dependency>

Note: Jakarta EE 9 adopts new API package namespace jakarta.xml.bind.*, so update import statements:

javax.xml.bind -> jakarta.xml.bind

This worked for me:

Import Service

import 'package:flutter/services.dart';

Then add:

@override
  Widget build(BuildContext context) {

    SystemChrome.setSystemUIOverlayStyle(SystemUiOverlayStyle(
      statusBarColor: Colors.white,
      statusBarBrightness: Brightness.dark,
    ));
    return MaterialApp(home: Scaffold(

I had same problem and it solved by defining kotlin gradle plugin version in build.gradle file.

change this

 classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"

to

 classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:1.3.50{or latest version}"

Quick summary, you can do either:

1. Include the JavaFX modules via --module-path and --add-modules like in José's answer.

   OR

2. Once you have JavaFX libraries added to your project (either manually or via maven/gradle import), add the module-info.java file similar to the one specified in this answer. (Note that this solution makes your app modular, so if you use other libraries, you will also need to add statements to require their modules inside the module-info.java file).

This answer is a supplement to Jose's answer.

The situation is this:

1. You are using a recent Java version, e.g. 13.
2. You have a JavaFX application as a Maven project.
3. In your Maven project you have the JavaFX plugin configured and JavaFX dependencies setup as per Jose's answer.
4. You go to the source code of your main class which extends Application, you right-click on it and try to run it.
5. You get an IllegalAccessError involving an "unnamed module" when trying to launch the app.

Exception running application org.jewelsea.demo.javafx.springboot.Main

OK, now you are kind of stuck and have no clue what is going on.

What has actually happened is this:

1. Maven has successfully downloaded the JavaFX dependencies for your application, so you don't need to separately download the dependencies or install a JavaFX SDK or module distribution or anything like that.
2. Idea has successfully imported the modules as dependencies to your project, so everything compiles OK and all of the code completion and everything works fine.

So it seems everything should be OK. BUT, when you run your application, the code in the JavaFX modules is failing when trying to use reflection to instantiate instances of your application class (when you invoke launch) and your FXML controller classes (when you load FXML). Without some help, this use of reflection can fail in some cases, generating the obscure IllegalAccessError. This is due to a Java module system security feature which does not allow code from other modules to use reflection on your classes unless you explicitly allow it (and the JavaFX application launcher and FXMLLoader both require reflection in their current implementation in order for them to function correctly).

This is where some of the other answers to this question, which reference module-info.java, come into the picture.

So let's take a crash course in Java modules:

• https://www.baeldung.com/java-9-modularity

The key part is this:

4.9. Opens

If we need to allow reflection of private types, but we don't want all of our code exposed, we can use the opens directive to expose specific packages.

But remember, this will open the package up to the entire world, so make sure that is what you want:

module my.module { opens com.my.package; }

So, perhaps you don't want to open your package to the entire world, then you can do:

4.10. Opens … To

Okay, so reflection is great sometimes, but we still want as much security as we can get from encapsulation. We can selectively open our packages to a pre-approved list of modules, in this case, using the opens…to directive:

module my.module { opens com.my.package to moduleOne, moduleTwo, etc.; }

So, you end up creating a src/main/java/module-info.java class which looks like this:

module org.jewelsea.demo.javafx.springboot {
    requires javafx.fxml;
    requires javafx.controls;
    requires javafx.graphics;
    opens org.jewelsea.demo.javafx.springboot to javafx.graphics,javafx.fxml;
}

Where, org.jewelsea.demo.javafx.springboot is the name of the package which contains the JavaFX Application class and JavaFX Controller classes (replace this with the appropriate package name for your application). This tells the Java runtime that it is OK for classes in the javafx.graphics and javafx.fxml to invoke reflection on the classes in your org.jewelsea.demo.javafx.springboot package. Once this is done, and the application is compiled and re-run things will work fine and the IllegalAccessError generated by JavaFX's use of reflection will no longer occur.

But what if you don't want to create a module-info.java file

If instead of using the the Run button in the top toolbar of IDE to run your application class directly, you instead:

1. Went to the Maven window in the side of the IDE.
2. Chose the javafx maven plugin target javafx.run.
3. Right-clicked on that and chose either Run Maven Build or Debug....

Then the app will run without the module-info.java file. I guess this is because the maven plugin is smart enough to dynamically include some kind of settings which allows the app to be reflected on by the JavaFX classes even without a module-info.java file, though I don't know how this is accomplished.

To get that setting transferred to the Run button in the top toolbar, right-click on the javafx.run Maven target and choose the option to Create Run/Debug Configuration for the target. Then you can just choose Run from the top toolbar to execute the Maven target.

Update: AdoptOpenJDK has changed its name to Adoptium, as part of its move to the Eclipse Foundation.

OpenJDK ? source code
Adoptium/AdoptOpenJDK ? builds

Difference between OpenJDK and AdoptOpenJDK

The first provides source-code, the other provides builds of that source-code.

• OpenJDK is an open-source project providing source-code (not builds) of an implementation of the Java platform as defined by:
  • the Java Specifications
  • Java Specification Request (JSR) documents published by Oracle via the Java Community Process
  • JDK Enhancement Proposal (JEP) documents published by Oracle via the OpenJDK project
• AdoptOpenJDK is an organization founded by some prominent members of the Java community aimed at providing binary builds and installers at no cost for users of Java technology.

Several vendors of Java & OpenJDK

Adoptium of the Eclipse Foundation, formerly known as AdoptOpenJDK, is only one of several vendors distributing implementations of the Java platform. These include:

• Eclipse Foundation (Adoptium/AdoptOpenJDK)
• Azul Systems
• Oracle
• Red Hat / IBM
• BellSoft
• SAP
• Amazon AWS
• … and more

See this flowchart of mine to help guide you in picking a vendor for an implementation of the Java platform. Click/tap to zoom.

Another resource: This comparison matrix by Azul Systems is useful, and seems true and fair to my mind.

Here is a list of considerations and motivations to consider in choosing a vendor and implementation.

Some vendors offer you a choice of JIT technologies.

Check if you're using an Ad Hoc Distribution provisioning profile and not an App Store Distribution provisioning profile instead, I was getting this error because of that.

This is the most simple solution if you just need to refresh the entire page

   refreshPage() {
    window.location.reload();
   }

Still surprised that no one proposed the shortest solution with align-center justify-center to center content vertically and horizontally. Check this CodeSandbox and code below:

<v-container fluid fill-height>
  <v-layout align-center justify-center>
    <v-flex>
      <!-- Some HTML elements... -->
    </v-flex>
  </v-layout>

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

Tutorial: unzip as expected. You need to set system variable PATH to include your directory with openjdk so you can type java -version in console.

JDK vs OpenJDK

Instead, use: sudo service redis-server start

I had the same problem, stopping/starting other services from within Ubuntu on WSL. This worked, where systemctl did not.

And one could reasonably wonder, "how would you know that the service name was 'redis-server'?" You can see them using service --status-all

You have a CryptoListPresenter _presenter but you are never initializing it. You should either be doing that when you declare it or in your initState() (or another appropriate but called-before-you-need-it method).

One thing I find that helps is that if I know a member is functionally 'final', to actually set it to final as that way the analyzer complains that it hasn't been initialized.

EDIT:

I see diegoveloper beat me to answering this, and that the OP asked a follow up.

@Jake - it's hard for us to tell without knowing exactly what CryptoListPresenter is, but depending on what exactly CryptoListPresenter actually is, generally you'd do final CryptoListPresenter _presenter = new CryptoListPresenter(...);, or

CryptoListPresenter _presenter;

@override
void initState() {
  _presenter = new CryptoListPresenter(...);
}

1. Can someone give a simple definition of what Record is?

A Record<K, T> is an object type whose property keys are K and whose property values are T. That is, keyof Record<K, T> is equivalent to K, and Record<K, T>[K] is (basically) equivalent to T.

2. Is Record<K,T> merely a way of saying "all properties on this object will have type T"? Probably not all objects, since K has some purpose...

As you note, K has a purpose... to limit the property keys to particular values. If you want to accept all possible string-valued keys, you could do something like Record<string, T>, but the idiomatic way of doing that is to use an index signature like { [k: string]: T }.

3. Does the K generic forbid additional keys on the object that are not K, or does it allow them and just indicate that their properties are not transformed to T?

It doesn't exactly "forbid" additional keys: after all, a value is generally allowed to have properties not explicitly mentioned in its type... but it wouldn't recognize that such properties exist:

declare const x: Record<"a", string>;
x.b; // error, Property 'b' does not exist on type 'Record<"a", string>'

and it would treat them as excess properties which are sometimes rejected:

declare function acceptR(x: Record<"a", string>): void;
acceptR({a: "hey", b: "you"}); // error, Object literal may only specify known properties

and sometimes accepted:

const y = {a: "hey", b: "you"};
acceptR(y); // okay

4. With the given example:

   type ThreeStringProps = Record<'prop1' | 'prop2' | 'prop3', string>
   

   Is it exactly the same as this?:

   type ThreeStringProps = {prop1: string, prop2: string, prop3: string}
   

Yes!

Hope that helps. Good luck!

I was getting this error. Turns out it only happened when I completely cleaned the RN caches (quite elaborate process) and then created a release build.

If I cleaned the caches, created a debug build and then a release build, everything worked. Bit worrying but works.

Note: My clean command is...

rm -r android/build ; rm -r android/app/src/release/res ; rm -r android/app/build/intermediates ; watchman watch-del-all ; rm -rf $TMPDIR/react-* ; npm start -- --reset-cache

This error can be due to many many things.

The key here seems the hint about error reading. I see you are working on a flash drive or something similar? Try to run the install on a local folder owned by your current user.

You could also try with sudo, that might solve a permission problem if that's the case.

Another reason why it cannot read could be because it has not downloaded correctly, or saved correctly. A little problem in your network could have caused that, and the cache clean would remove the files and force a refetch but that does not solve your problem. That means it would be more on the save part, maybe it didn't save because of permissions, maybe it didn't not save correctly because it was lacking disk space...

I did it like this. hope this will help you.

This worked for me:

File >> Project Structure >> Modules >> Dependency >> + (on left-side of window)

clicking the "+" sign will let you designate the directory where you have unpacked JavaFX's "lib" folder.

Scope is Compile (which is the default.) You can then edit this to call it JavaFX by double-clicking on the line.

then in:

Run >> Edit Configurations

Add this line to VM Options:

--module-path /path/to/JavaFX/lib --add-modules=javafx.controls

(oh and don't forget to set the SDK)

I got same problem. So I looked into the axios document. I found it. you can do it like this. this is easiest way. and super simple.

https://www.npmjs.com/package/axios#using-applicationx-www-form-urlencoded-format

var params = new URLSearchParams();
params.append('param1', 'value1');
params.append('param2', 'value2');
axios.post('/foo', params);

You can use .then,.catch.

Although I've tried all the previous answers, only the following one worked out:

1 - Open Powershell (as Admin)

2 - Run:

[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12

3 - Run:

Install-PackageProvider -Name NuGet

I stumbled upon another possible reason of this error. If you use NTFS symbolic links in your project tree, and probably subst'ed drives, you may get this error even if they point to your local drive. If this is the case, try to avoid the situation when .resx files are reached via symlinks.

On ubuntu you can add this PPA Repository and use it to install python 3.7: https://launchpad.net/~jonathonf/+archive/ubuntu/python-3.7

Or a different PPA that provides several Python versions is Deadsnakes: https://launchpad.net/~deadsnakes/+archive/ubuntu/ppa

See also here: https://askubuntu.com/questions/865554/how-do-i-install-python-3-6-using-apt-get (I know it says 3.6 in the url, but the deadsnakes ppa also contains 3.7 so you can use it for 3.7 just the same)

If you want "official" you'd have to install it from the sources from the site, get the code (which you already downloaded) and do this:

tar -xf Python-3.7.0.tar.xz
cd Python-3.7.0
./configure
make
sudo make install        <-- sudo is required.

This might take a while

This link helped.

Spring Boot auto-configuration tries to configure beans automatically based on the dependencies added to the classpath. And because we have a JPA dependency (spring-data-starter-jpa) on our classpath, it tries to configure it.

The problem: Spring boot doesn't have the all the info needed to configure the JPA data source i.e. the JDBC connection properties. Solutions:

1. provide the JDBC connection properties (best)
2. postpone supplying connection properties by excluding some AutoConfig classes (temporary - should be removed eventually)

The above link excludes the DataSourceAutoConfiguration.class with

@SpringBootApplication(exclude={DataSourceAutoConfiguration.class})

But this didn't work for me. I instead, had to exclude 2 AutoConfig classes:

@SpringBootApplication(exclude = {DataSourceAutoConfiguration.class, XADataSourceAutoConfiguration.class})

I had this issue with offline mode enable. I disabled offline mode and synced.

• Open the Preferences, by clicking File > Settings.
• In the left pane, click Build, Execution, Deployment > Gradle.
• Uncheck the Offline work.
• Apply changes and sync project again.

Try this

products.sort(function (a, b) {
  return a.title.rendered - b.title.rendered;
});

OR

You can import lodash/underscore library, it has many build functions available for manipulating, filtering, sorting the array and all.

Using underscore: (below one is just an example)

import * as _ from 'underscore';
let sortedArray = _.sortBy(array, 'title'); 

Use FirebaseMessaging instead

 FirebaseMessaging.getInstance().getToken()
    .addOnCompleteListener(new OnCompleteListener<String>() {
        @Override
        public void onComplete(@NonNull Task<String> task) {
          if (!task.isSuccessful()) {
            Log.w(TAG, "Fetching FCM registration token failed", task.getException());
            return;
          }

          // Get new FCM registration token
          String token = task.getResult();

          // Log and toast
          String msg = getString(R.string.msg_token_fmt, token);
          Log.d(TAG, msg);
          Toast.makeText(MainActivity.this, msg, Toast.LENGTH_SHORT).show();
        }
    });

You are calling:

JSON.parse(scatterSeries)

But when you defined scatterSeries, you said:

var scatterSeries = []; 

When you try to parse it as JSON it is converted to a string (""), which is empty, so you reach the end of the string before having any of the possible content of a JSON text.

scatterSeries is not JSON. Do not try to parse it as JSON.

data is not JSON either (getJSON will parse it as JSON automatically).

ch is JSON … but shouldn't be. You should just create a plain object in the first place:

var ch = {
    "name": "graphe1",
    "items": data.results[1]
};

scatterSeries.push(ch);

In short, for what you are doing, you shouldn't have JSON.parse anywhere in your code. The only place it should be is in the jQuery library itself.

The recommended method worked for me but after updating my library implementation 'androidx.appcompat:appcompat:1.1.0'

Implement as below

 val onBackPressedCallback = object : OnBackPressedCallback(true) {
        override fun handleOnBackPressed() {
            // Handle the back button event
        }
    }
    requireActivity().onBackPressedDispatcher.addCallback(this, onBackPressedCallback)

using Kotlin

Browser have cross domain security at client side which verify that server allowed to fetch data from your domain. If Access-Control-Allow-Origin not available in response header, browser disallow to use response in your JavaScript code and throw exception at network level. You need to configure cors at your server side.

You can fetch request using mode: 'cors'. In this situation browser will not throw execption for cross domain, but browser will not give response in your javascript function.

So in both condition you need to configure cors in your server or you need to use custom proxy server.

If you want a free simple location map showing a single marked location, for your website, Then

When you adding assets directory in pubspec.yaml file give more attention in to spaces

this is wrong

flutter:

This is the correct way,

  assets:
    - assets/images/

Because the bootstrap-select is a bootstrap component and therefore you need to include it in your code as you did for your V3

NOTE: this component only works in boostrap-4 since version 1.13.0

In most cases, the blocked response should not affect the web page's behavior and the CORB error message can be safely ignored. For example, the warning may occur in cases when the body of the blocked response was empty already, or when the response was going to be delivered to a context that can't handle it (e.g., a HTML document such as a 404 error page being delivered to an tag).

I had to clean my browser's cache, I was reading in this link, that, if the request get a empty response, we get this warning error. I was getting some CORS on my request, and so the response of this request got empty, All I had to do was clear the browser's cache, and the CORS got away. I was receiving CORS because the chrome had saved the PORT number on the cache, The server would just accept localhost:3010 and I was doing localhost:3002, because of the cache.

I had the same problem and passing auth_plugin='mysql_native_password' did not work, because I accidentally installed mysql-connector instead of mysql-connector-python (via pip3). Just leaving this here in case it helps someone.

I think a more flexible option would be to wrap the Text() with Align() like so:

Align(
  alignment: Alignment.center, // Align however you like (i.e .centerRight, centerLeft)
  child: Text("My Text"),
),

Using Center() seems to ignore TextAlign entirely on the Text widget. It will not align TextAlign.left or TextAlign.right if you try, it will remain in the center.

I would use a https://docs.flutter.io/flutter/widgets/Stack-class.html to be able to freely position widgets.

To create circles

  new BoxDecoration(
    color: effectiveBackgroundColor,
    image: backgroundImage != null
      ? new DecorationImage(image: backgroundImage, fit: BoxFit.cover)
      : null,
    shape: BoxShape.circle,
  ),

and https://docs.flutter.io/flutter/widgets/Transform/Transform.rotate.html to position the white dots.

npm install --save-dev @angular-devkit/build-angular

It's Install @angular-devkit/build-angular as dev dependency. This package is newly introduced in Angular 6.0

npm i --save-dev @angular-devkit/build-angular

This code install @angular-devkit/build-angular as dev dependency.

100% TESTED.

It's an open issue #900 on GitHub, unfortunately at this point of time it looks that in Angular CLI there's nothing like ng remove/rm/..., only using npm uninstall DEPENDENCY is the current workaround.

For angular material you should use fontSet input to change the font family:

<link href="https://fonts.googleapis.com/css?family=Material+Icons|Material+Icons+Outlined|Material+Icons+Two+Tone|Material+Icons+Round|Material+Icons+Sharp"
rel="stylesheet" />

<mat-icon>edit</mat-icon>
<mat-icon fontSet="material-icons-outlined">edit</mat-icon>
<mat-icon fontSet="material-icons-two-tone">edit</mat-icon>
...

npm install --save bootstrap

afterwards, inside angular.json (previously .angular-cli.json) inside the project's root folder, find styles and add the bootstrap css file like this:

for angular 6

"styles": [
          "../node_modules/bootstrap/dist/css/bootstrap.min.css",
          "styles.css"
],

for angular 7

"styles": [
          "node_modules/bootstrap/dist/css/bootstrap.min.css",
          "src/styles.css"
],

In my case the trouble was I didn't put the components that contain the datasource in the declarations of main module.

NgModule({
  imports: [
    EnterpriseConfigurationsRoutingModule,
    SharedModule
  ],
  declarations: [
    LegalCompanyTypeAssignComponent,
    LegalCompanyTypeAssignItemComponent,
    ProductsOfferedListComponent,
    ProductsOfferedItemComponent,
    CustomerCashWithdrawalRangeListComponent,
    CustomerCashWithdrawalRangeItemComponent,
    CustomerInitialAmountRangeListComponent,
    CustomerInitialAmountRangeItemComponent,
    CustomerAgeRangeListComponent,
    CustomerAgeRangeItemComponent,
    CustomerAccountCreditRangeListComponent, //<--This component contains the dataSource
    CustomerAccountCreditRangeItemComponent,
  

  ],

The component contains the dataSource:

export class CustomerAccountCreditRangeListComponent implements OnInit {

  @ViewChild(MatPaginator) set paginator(paginator: MatPaginator){
    this.dataSource.paginator = paginator;
  }
  @ViewChild(MatSort) set sort(sort: MatSort){
    this.dataSource.sort = sort;
  }

  dataSource = new MatTableDataSource(); //<--The dataSource used in HTML
  loading: any;
  resultsLength: any;
  displayedColumns: string[] = ["id", "desde", "hasta", "tipoClienteNombre", "eliminar"];
  data: any;

  constructor(
    private crud: CustomerAccountCreditRangeService,
    public snackBar: MatSnackBar,
    public dialog: MatDialog,
    private ui: UIComponentsService
  ) {
  }

This is for Angular 9

In addition to other answers which helped me, you can also add to surrounding div. In my case this was for sign on with user Name/Password fields.

<div (keyup.enter)="login()" class="container-fluid">

A better solution is explained in the official explanation. I left the answer I have given before under the horizontal line.

According to the solution there:

Use an external tag and write down the following code below in the top-level build.gradle file. You're going to change the version to a variable rather than a static version number.

ext {
    compileSdkVersion = 26
    supportLibVersion = "27.1.1"
}

Change the static version numbers in your app-level build.gradle file, the one has (Module: app) near.

android {
    compileSdkVersion rootProject.ext.compileSdkVersion // It was 26 for example
    // the below lines will stay
}

// here there are some other stuff maybe

dependencies {
    implementation "com.android.support:appcompat-v7:${rootProject.ext.supportLibVersion}"
    // the below lines will stay
}

Sync your project and you'll get no errors.

You don't need to add anything to Gradle scripts. Install the necessary SDKs and the problem will be solved.

In your case, install the libraries below from Preferences > Android SDK or Tools > Android > SDK Manager

Full Steps For MySQL 8

Connect to MySQL

$ mysql -u root -p
Enter password: (enter your root password)

Reset your password

(Replace your_new_password with the password you want to use)

mysql> ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'your_new_password';
mysql> FLUSH PRIVILEGES;
mysql> quit

Then try connecting using node

For implementing the rounded border button with a border color use this

OutlineButton(
                    child: new Text("Button Text"),borderSide: BorderSide(color: Colors.blue),
                    onPressed: null,
                    shape: new RoundedRectangleBorder(borderRadius: new BorderRadius.circular(20.0))
                ),

ALTER USER 'mysqlUsername'@'localhost' IDENTIFIED WITH mysql_native_password BY 'mysqlUsernamePassword';

Remove quotes (') after ALTER USER and keep quote (') after mysql_native_password BY

It is working for me also.

I had a similar issue. Back-revving RXJS from 6.x to the latest 5.x release fixed it for Angular 5.2.x.

Open package.json.

Change "rxjs": "^6.0.0", to "rxjs": "^5.5.10",

run npm update

Edit file: C:\Users\kpate\hw6\python-zulip-api\zulip_bots\setup.py in line 108

to

rcode = pip.main(['install', '-r', req_path, '--quiet'])

do

rcode = getattr(pip, '_main', pip.main)(['install', '-r', req_path, '--quiet'])´

Just run ng update @angular/cli in your console. You might find some vulnerabilities after running the command (if using npm), but then just runnpm audit fix in the console to fix them. This command will scan the project for any vulnerabilities and it will also fix compatibility issues by installing updates to these dependencies. If you do not wish to auto fix these vulnerabilities immediately, you can perform a Dry Run: by running npm audit fix --dry-run -json in the console. This will give you an idea of what the command npm audit fix will do, in the form of json in the console.

Support for TLS 1.0 and 1.1 was dropped for PyPI. If your system does not use a more recent version, it could explain your error.

Could you try reinstalling pip system-wide, to update your system dependencies to a newer version of TLS?

This seems to be related to Unable to install Python libraries

See Dominique Barton's answer:

Apparently pip is trying to access PyPI via HTTPS (which is encrypted and fine), but with an old (insecure) SSL version. Your system seems to be out of date. It might help if you update your packages.

On Debian-based systems I'd try:

apt-get update && apt-get upgrade python-pip

On Red Hat Linux-based systems:

yum update python-pip # (or python2-pip, at least on Red Hat Linux 7)

On Mac:

sudo easy_install -U pip

You can also try to update openssl separately.

Go to your tsconfig.json file and change "noImplicitReturns": false then add "strictPropertyInitialization": false to your tsconfig.json file under "compilerOptions" property. Here is what my tsconfig.json file looks like

tsconfig.json

{
  ...
  "compilerOptions": {
        ....
        "noImplicitReturns": false,
        ....
        "strictPropertyInitialization": false
  },
  "angularCompilerOptions": {
     ......
  }  
}

Hope this will help !! Good Luck

You can simply use this

!unzip file_location

As we recently posted on the React blog, in the vast majority of cases you don't need getDerivedStateFromProps at all.

If you just want to compute some derived data, either:

1. Do it right inside render
2. Or, if re-calculating it is expensive, use a memoization helper like memoize-one.

Here's the simplest "after" example:

import memoize from "memoize-one";

class ExampleComponent extends React.Component {
  getDerivedData = memoize(computeDerivedState);

  render() {
    const derivedData = this.getDerivedData(this.props.someValue);
    // ...
  }
}

To start the standalone Device Monitor application, enter the following on the command line in the android-sdk/tools/ directory:

monitor

You can then link the tool to a connected device by selecting the device from the Devices pane. If you have trouble viewing panes or windows, select Window > Reset Perspective from the menu bar.

• Note: Each device can be attached to only one debugger process at a time. So, for example, if you are using Android Studio to debug your app on a device, you need to disconnect the Android Studio debugger from the device before you attach a debugger process from the Android Device Monitor.

reference : https://developer.android.com/studio/profile/monitor.html

=> You Can change minSdkVersion 16 And open Device File Explorer

• Device File Explorer work same as a Android Device Monitor

My project use ButterKnife and Retro lambda, setting JavaVersion.VERSION_1_8 will not work. It always blames at ButterKnife static interface function until I found this Migrate from Retrolambda

TL;DR

Just add JavaVersion.VERSION_1_8 and completely REMOVE retrolambda from your project. It will build successfully.

You can simply use named constructors for creating different types of buttons with icons. For instance

FlatButton.icon(onPressed: null, icon: null, label: null);
RaisedButton.icon(onPressed: null, icon: null, label: null);

But if you have specfic requirements then you can always create custom button with different layouts or simply wrap a widget in GestureDetector.

You can see the button "Code" in the attached screenshot, press it and you can get your code in many different languages including PHP cURL

I had the SAME issue today and it was driving me nuts!!! What I had done was upgrade to node 8.10 and upgrade my NPM to the latest I uninstalled angular CLI

npm uninstall -g angular-cli
npm uninstall --save-dev angular-cli

I then verified my Cache from NPM if it wasn't up to date I cleaned it and ran the install again if npm version is < 5 then use npm cache clean --force

npm install -g @angular/cli@latest

and created a new project file and create a new angular project.

I have solved this issue about $ sudo docker run hello-world following the Docker doc.

If you are behind an HTTP Proxy server of corporate, this may solve your problem.

Docker doc also displays other situation about HTTP proxy setting.

Note that there is an unrelated issue in your code but that could bite you later: you should return res.json() or you will not catch any error occurring in JSON parsing or your own function processing data.

Back to your error: You cannot have a TypeError: failed to fetch with a successful request. You probably have another request (check your "network" panel to see all of them) that breaks and causes this error to be logged. Also, maybe check "Preserve log" to be sure the panel is not cleared by any indelicate redirection. Sometimes I happen to have a persistent "console" panel, and a cleared "network" panel that leads me to have error in console which is actually unrelated to the visible requests. You should check that.

Or you (but that would be vicious) actually have a hardcoded console.log('TypeError: failed to fetch') in your final .catch ;) and the error is in reality in your .then() but it's hard to believe.

Alternatively if you enable developer mode and (ADB) is still needed you can use connect to the device.

To enable developer Mode you go to Phone Settings > About Phone > tap buildnumber 7 times

once you have it enabled and have the device connected you can start seeing the device in VSCode

I had the exact same issue. The following thread helped me solve it. Just set your Compile SDK version to Android P.

https://stackoverflow.com/a/49172361/1542720

I fixed this issue by selecting:

API 27+: Android API 27, P preview (Preview)

in the project structure settings. the following image shows my settings. The 13 errors that were coming while building the app, have disappeared.

Build cache is generated on application run time when a temporary file automatically generated in dart-tools folder, android folder and iOS folder. Clear command will delete the build tools and dart directories in flutter project so when we re-compile the project it will start from beginning. This command is mostly used when our project is showing debug error or running related error. In this answer we would Clear Build Cache in Flutter Android iOS App and Rebuild Project structure again.

1. Open your flutter project folder in Command Prompt or Terminal. and type flutter clean command and press enter.

2. After executing flutter clean command we would see that it will delete the dart-tools folder, android folder and iOS folder in our application with debug file. This might take some time depending upon your system speed to clean the project.

For more info, see https://flutter-examples.com/clear-build-cache-in-flutter-app/

In my case:

Windows 10 and Docker Desktop works:

docker-compose -f .docker/docker-compose.yml exec php env COMPOSER_MEMORY_LIMIT=-1 composer require fideloper/proxy

If anybody has this error using phonegap or cordova with the cordova-plugin-fcm-ng or cordova-plugin-fcm plugin, the solution that worked for me is creating the extra config file for gradle "build-extras.gradle" in the \platforms\android\app folder, and putting the following lines in it

configurations.all {
 resolutionStrategy {
  force 'com.google.firebase:firebase-messaging:18.0.0'
  force 'com.google.firebase:firebase-core:16.0.8'
 }
}

I found this solution reading this page https://github.com/facebook/react-native/issues/25371, in particular comment of shreyakupadhyay on 30/07/19 and consulting https://developers.google.com/android/guides/releases#may_07_2019 about last libraries version.

I was having similar problem but I came out of the solution the problem was that you were using any thing in the dependency that correspond to same domain but with different versions make sure those all are same

Problem

The trim() method removes whitespace from both sides of a string.

Source

Solution

You can use a Javascript replace method to remove white space like

"hello world".replace(/\s/g, "");

Example

var out = "hello world".replace(/\s/g, "");_x000D_
console.log(out);

To remove complete conda environment :

conda remove --name YOUR_CONDA_ENV_NAME --all

            Container(
         height: 50,
          // margin: EdgeInsets.only(top: 20),
          decoration: BoxDecoration(
              color: Colors.tealAccent,
              borderRadius: BorderRadius.circular(32)),
          child: TextFormField(
            cursorColor: Colors.black,
            // keyboardType: TextInputType.,
            decoration: InputDecoration(
              hintStyle: TextStyle(fontSize: 17),
              hintText: 'Search your trips',
              suffixIcon: Icon(Icons.search),
              border: InputBorder.none,
              contentPadding: EdgeInsets.all(18),
            ),

We can use ls and many other Linux commands in Windows cmd. Just follow these steps.

Steps:

1) Install Git in your computer - https://git-scm.com/downloads.

2) After installing Git, go to the folder in which Git is installed. Mostly it will be in C drive and then Program Files Folder.

3) In Program Files folder, you will find the folder named Git, find the bin folder which is inside usr folder in the Git folder.

In my case, the location for bin folder was - C:\Program Files\Git\usr\bin

4) Add this location (C:\Program Files\Git\usr\bin) in path variable, in system environment variables.

5) You are done. Restart cmd and try to run ls and other Linux commands.

The next solution helped me. Add to build.gradle

 compileKotlin {
    kotlinOptions.jvmTarget = "1.8"
}

compileTestKotlin {
    kotlinOptions.jvmTarget = "1.8"
}

The problem for me seems to have been how the user has been setup on my local machine to. Using the command
git push -u origin master
was causing the error. Removing the switch -u to have
git push origin master
solved it for me. It can be scary to imagine how user setup can result in an error related to LibreSSL.

If you have a standard code signing certificate, some time will be needed for your application to build trust. Microsoft affirms that an Extended Validation (EV) Code Signing Certificate allows us to skip this period of trust-building. According to Microsoft, extended validation certificates allow the developer to immediately establish a reputation with SmartScreen. Otherwise, the users will see a warning like "Windows Defender SmartScreen prevented an unrecognized app from starting. Running this app might put your PC at risk.", with the two buttons: "Run anyway" and "Don't run".

Another Microsoft resource states the following (quote): "Although not required, programs signed by an EV code signing certificate can immediately establish a reputation with SmartScreen reputation services even if no prior reputation exists for that file or publisher. EV code signing certificates also have a unique identifier which makes it easier to maintain reputation across certificate renewals."

My experience is as follows. Since 2005, we have been using regular (non-EV) code signing certificates to sign .MSI, .EXE and .DLL files with time stamps, and there has never been a problem with SmartScreen until 2018, when there was just one case when it took 3 days for a beta version of our application to build trust since we have released it to beta testers, and it was in the middle of certificate validity period. I don't know what SmartScreen might not like in that specific version of our application, but there have been no SmartScreen complaints since then. Therefore, if your certificate is a non-EV, it is a signed application (such as an .MSI file) that will build trust over time, not a certificate. For example, a certificate can be issued a few months ago and used to sign many files, but for each signed file you publish, it may take a few days for SmartScreen to stop complaining about the file after publishing, as was in our case in 2018.

As a conclusion, to avoid the warning completely, i.e. prevent it from happening even suddenly, you need an Extended Validation (EV) code signing certificate.

Just default the variable to the expected type:

(number=1) => ...
(number=1.0) => ...
(string='str') ...

I know this issue has been asked two years ago, but I just had this issue and the fix I used really helped.

If you are doing two queries with the same Context - you might need to remove the AsNoTracking. If you do use AsNoTracking you are creating a new data-reader for each read. Two data readers cannot read the same data.

If you just want to read an image in Python using the specified libraries only, I will go with matplotlib

In matplotlib :

import matplotlib.image
read_img = matplotlib.image.imread('your_image.png')

I had the same error message but for a totally different reason.

Being new to docker, I issued

docker run -it <crypticalId>

where <crypticalId> was the id of my newly created container.

But, the run command wants the id of an image, not a container.

To start a container, docker wants

docker start -i <crypticalId>

You can do this two options:

1. Add classpath 'com.google.gms:google-services:3.2.0' in ur project: build.gradle dependencies and
2. Replace your module: build.gradle in dependency from complile with implementation and you wont get any warning messages.

Perhaps you can try to sync up the dependencies by executing 'flutter pub get' in terminal.

Unfortunately, the answer to your question of whether there is official Material support for selecting the time is "No", but it's currently an open issue on the official Material2 GitHub repo: https://github.com/angular/material2/issues/5648

Hopefully this changes soon, in the mean time, you'll have to fight with the 3rd-party ones you've already discovered. There are a few people in that GitHub issue that provide their self-made workarounds that you can try.

edit2, I figured out a new solution without the need of setting index

newdf=pd.concat([df1,df2]).drop_duplicates(keep=False)

Okay i found the answer of highest vote already contain what I have figured out. Yes, we can only use this code on condition that there are no duplicates in each two dfs.

I have a tricky method. First we set ’Name’ as the index of two dataframe given by the question. Since we have same ’Name’ in two dfs, we can just drop the ’smaller’ df’s index from the ‘bigger’ df. Here is the code.

df1.set_index('Name',inplace=True)
df2.set_index('Name',inplace=True)
newdf=df1.drop(df2.index)

Whenever you try to show a Link on a page thats outside the BrowserRouter you will get that error.

This error message is essentially saying that any component that is not a child of our <Router> cannot contain any React Router related components.

You need to migrate your component hierarchy to how you see it in the first answer above. For anyone else reviewing this post who may need to look at more examples.

Let's say you have a Header.jscomponent that looks like this:

import React from 'react';
import { Link } from 'react-router-dom';

const Header = () => {
    return (
        <div className="ui secondary pointing menu">
            <Link to="/" className="item">
                Streamy
            </Link>
            <div className="right menu">
                <Link to="/" className="item">
                    All Streams
                </Link>
            </div>
        </div>
    );
};

export default Header;

And your App.js file looks like this:

import React from 'react';
import { BrowserRouter, Route, Link } from 'react-router-dom';
import StreamCreate from './streams/StreamCreate';
import StreamEdit from './streams/StreamEdit';
import StreamDelete from './streams/StreamDelete';
import StreamList from './streams/StreamList';
import StreamShow from './streams/StreamShow';
import Header from './Header';

const App = () => {
  return (
    <div className="ui container">
      <Header />
      <BrowserRouter>
        <div>
        <Route path="/" exact component={StreamList} />
        <Route path="/streams/new" exact component={StreamCreate} />
        <Route path="/streams/edit" exact component={StreamEdit} />
        <Route path="/streams/delete" exact component={StreamDelete} />
        <Route path="/streams/show" exact component={StreamShow} />
        </div> 
      </BrowserRouter>
    </div>
  );
};

export default App;

Notice that the Header.js component is making use of the Link tag from react-router-dom but the componet was placed outside the <BrowserRouter>, this will lead to the same error as the one experience by the OP. In this case, you can make the correction in one move:

import React from 'react';
import { BrowserRouter, Route } from 'react-router-dom';
import StreamCreate from './streams/StreamCreate';
import StreamEdit from './streams/StreamEdit';
import StreamDelete from './streams/StreamDelete';
import StreamList from './streams/StreamList';
import StreamShow from './streams/StreamShow';
import Header from './Header';

const App = () => {
  return (
    <div className="ui container">
      <BrowserRouter>
        <div>
        <Header />
        <Route path="/" exact component={StreamList} />
        <Route path="/streams/new" exact component={StreamCreate} />
        <Route path="/streams/edit" exact component={StreamEdit} />
        <Route path="/streams/delete" exact component={StreamDelete} />
        <Route path="/streams/show" exact component={StreamShow} />
        </div> 
      </BrowserRouter>
    </div>
  );
};

export default App;

Please review carefully and ensure you have the <Header /> or whatever your component may be inside of not only the <BrowserRouter> but also inside of the <div>, otherwise you will also get the error that a Router may only have one child which is referring to the <div> which is the child of <BrowserRouter>. Everything else such as Route and components must go within it in the hierarchy.

So now the <Header /> is a child of the <BrowserRouter> within the <div> tags and it can successfully make use of the Link element.

In my case the problem was in parameters arrangement. Initially I had --name parameter after environment parameters and then volume and attach_dbs parameters, and image at the end of command like below.

docker run -p 1433:1433 -e sa_password=myComplexPwd -e ACCEPT_EULA=Y --name sql1 -v c:/temp/:c:/temp/ attach_dbs="[{'dbName':'TestDb','dbFiles':['c:\\temp\\TestDb.mdf','c:\\temp\\TestDb_log.ldf']}]" -d microsoft/mssql-server-windows-express

After rearranging the parameters like below everything worked fine (basically putting --name parameter followed by image name).

docker run -d -p 1433:1433 -e sa_password=myComplexPwd -e ACCEPT_EULA=Y --name sql1 microsoft/mssql-server-windows-express -v C:/temp/:C:/temp/ attach_dbs="[{'dbName':'TestDb','dbFiles':['C:\\temp\\TestDb.mdf','C:\\temp\\TestDb_log.ldf']}]"

This examples shows calling a method

  final GlobalKey<ChildPageState> _key = GlobalKey();

  @override

    return Scaffold(
      appBar: AppBar(title: Text("Parent")),
      body: Center(

                  onPressed: () => _key.currentState.methodInChild(), // calls method in child
                ),
              ),
            ),
            Text("Above = Parent\nBelow = Child"),
            Expanded(

                key: _key,
                function: methodInParent,
              ),
            ),
          ],
        ),
      ),
    );
  }

  methodInParent() => Fluttertoast.showToast(msg: "Method called in parent", gravity: ToastGravity.CENTER);
}

class ChildPage extends StatefulWidget {
  final Function function;

  ChildPage({Key key, this.function}) : super(key: key);

  @override

  }

  methodInChild() => Fluttertoast.showToast(msg: "Method called in child");
}

I was getting this Swagger error when I created Version 2 of my api using version headers instead of url versioning. The workaround was to add [Obsolete] attributes to the Version 1 methods then use SwaggerGeneratorOptions to ignore the obsolete api methods in Startup -> ConfigureServices method.

services.AddSwaggerGen(c =>
{
    c.SwaggerGeneratorOptions.IgnoreObsoleteActions = true;
    c.SwaggerDoc("v2", new Info { Title = "My API", Version = "v2" });
});

Might sound silly but I simply called npm i node-fetch --save in the wrong project. Make sure you are in the correct directory.

Removing the v=...& part from the url, and only keep the list=... part. The main problem being the special character &, interpreted by the shell.

You can also quote your 'url' in your command.

I’m lazy and my memory is bad, so I decided to create easycolab which is easier to memorize and type:

import easycolab as ec
ec.mount()

Make sure to install it first: !pip install easycolab

The mount() method basically implement this:

from google.colab import drive
drive.mount(‘/content/drive’)
cd ‘/content/gdrive/My Drive/’

If you want to check the python version in a particular cond environment you can also use conda list python

If you want to use default mailtrip.io you don't need to modify mail.php file.

1. Create account on mailtrip.io
2. Go to Inboxes > My Inbox > SMTP Settings > Integration Laravel
3. Modify .env file and replace all nulls of correct credentials:

MAIL_HOST=smtp.mailtrap.io
MAIL_PORT=2525
MAIL_USERNAME=null
MAIL_PASSWORD=null
MAIL_ENCRYPTION=null

4. Run:

php artisan config:cache

If you are using Gmail there is an instruction for Gmail: https://stackoverflow.com/a/64582540/7082164

Just Type the Drive Location you want to work with: This worked for me! For example you want to change to D drive in windows:

D:\

If you want to change to particular folder in the drive:

cd D:\Newfolder

All I did is go to my project directory from the cmd (command prompt) I typed java -version.it told me what version it was looking for. so I Installed that version and I changed the path to were the jdk of that version was located .

As others have pointed out, the cd command needs to start with a percentage sign:

%cd SwitchFrequencyAnalysis

Difference between % and !

Google Colab seems to inherit these syntaxes from Jupyter (which inherits them from IPython). Jake VanderPlas explains this IPython behaviour here. You can see the excerpt below.

If you play with IPython's shell commands for a while, you might notice that you cannot use !cd to navigate the filesystem:

In [11]: !pwd 
/home/jake/projects/myproject

In [12]: !cd ..

In [13]: !pwd 
/home/jake/projects/myproject 

The reason is that shell commands in the notebook are executed in a temporary subshell. If you'd like to change the working directory in a more enduring way, you can use the %cd magic command:

In [14]: %cd ..
/home/jake/projects

Another way to look at this: you need % because changing directory is relevant to the environment of the current notebook but not to the entire server runtime.

In general, use ! if the command is one that's okay to run in a separate shell. Use % if the command needs to be run on the specific notebook.

As an alternative, you can install 7.1 version of mcrypt and create a symbolic link to it:

Install php7.1-mcrypt:

sudo apt install php7.1-mcrypt

Create a symbolic link:

sudo ln -s /etc/php/7.1/mods-available/mcrypt.ini /etc/php/7.2/mods-available

After enabling mcrypt by sudo phpenmod mcrypt, it gets available.

Triple check the name and path of the file. In my case I had something like this content in the target folder:

lib
    foobar.bundle.js
    foobr.css

And this link:

<link rel="stylesheet" href="lib/foobar.css">

I guess that the browser was trying to load the JavaScript file and complaining about its MIME type instead of giving me a file not found error.

This is because map.keys() returns an iterator. *ngFor can work with iterators, but the map.keys() will be called on every change detection cycle, thus producing a new reference to the array, resulting in the error you see. By the way, this is not always an error as you would traditionally think of it; it may even not break any of your functionality, but suggests that you have a data model which seems to behave in an insane way - changing faster than the change detector checks its value.

If you do no want to convert the map to an array in your component, you may use the pipe suggested in the comments. There is no other workaround, as it seems.

P.S. This error will not be shown in the production mode, as it is more like a very strict warning, rather than an actual error, but still, this is not a good idea to leave it be.

You can get headers using below code

let main_headers = {}
this.http.post(url,
  {email: this.username, password: this.password},
  {'headers' : new HttpHeaders ({'Content-Type' : 'application/json'}), 'responseType': 'text', observe:'response'})
  .subscribe(response => {
    const keys = response.headers.keys();
    let headers = keys.map(key => {
      `${key}: ${response.headers.get(key)}`
        main_headers[key] = response.headers.get(key)
       }
      );
  });

later we can get the required header form the json object.

SciPy's imresize() method was another resize method, but it will be removed starting with SciPy v 1.3.0 . SciPy refers to PIL image resize method: Image.resize(size, resample=0)

size – The requested size in pixels, as a 2-tuple: (width, height).
resample – An optional resampling filter. This can be one of PIL.Image.NEAREST (use nearest neighbour), PIL.Image.BILINEAR (linear interpolation), PIL.Image.BICUBIC (cubic spline interpolation), or PIL.Image.LANCZOS (a high-quality downsampling filter). If omitted, or if the image has mode “1” or “P”, it is set PIL.Image.NEAREST.

You are missing a 'b' I think?

sudo service mongod start

should be

sudo service mongodb start

I think this is the case?

The way I did it can be found in this Stack Overflow question.

It is important to use resetModules before each test and then dynamically import the module inside the test:

describe('environmental variables', () => {
  const OLD_ENV = process.env;

  beforeEach(() => {
    jest.resetModules() // Most important - it clears the cache
    process.env = { ...OLD_ENV }; // Make a copy
  });

  afterAll(() => {
    process.env = OLD_ENV; // Restore old environment
  });

  test('will receive process.env variables', () => {
    // Set the variables
    process.env.NODE_ENV = 'dev';
    process.env.PROXY_PREFIX = '/new-prefix/';
    process.env.API_URL = 'https://new-api.com/';
    process.env.APP_PORT = '7080';
    process.env.USE_PROXY = 'false';

    const testedModule = require('../../config/env').default

    // ... actual testing
  });
});

If you look for a way to load environment values before running the Jest look for the answer below. You should use setupFiles for that.

After yum install python3-pip, check the name of the installed binary. e.g.

ll /usr/bin/pip*

On my CentOS 7, it is named as pip-3 instead of pip3.

Hello from Docker!
This message shows that your installation appears to be working correctly.

To generate this message, Docker took the following steps:
 1. The Docker client contacted the Docker daemon.
 2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
    (amd64)
 3. The Docker daemon created a new container from that image which runs the
    executable that produces the output you are currently reading.
 4. The Docker daemon streamed that output to the Docker client, which sent it
    to your terminal.

Unchecking proxy and SSL Certificate Verification didn't work for me.

Unsetting PROXY environment variables did the trick.

I've never seen this error before, but whenever I can't get Xcode and React-Native to play well together, I do a couple of things. Check what version of Xcode I'm working with. If it needs to be updated, I update it. Then clearing watchman and the cache are the second place I go. I don't use the reset cache command. It always says that I need to verify the cache, so I skip that (you can do it though, I just get confused). I use rm -rf $TMPDIR/react-* to get rid of any cached builds. If that doesn't work, I try to build the app in Xcode, then work my way from there, to build it with react-native run-ios. With this error message, it seems you might start by trying to build it with Xcode. Hope that helps...let me know your progress with it. Good luck! (Also, you could update to RN 0.51 as another attempt to get your versions synced.)

urllib is a standard python library (built-in) so you don't have to install it. just import it if you need to use request by:

import urllib.request

if it's not work maybe you compiled python in wrong way, so be kind and give us more details.

I solve that with

First delete package-lock.json

npm cache clean --force

then update npm

npm i npm@latest -g

then use npm install command

npm install 

It used to work with the older versions of MongoDb client ~ 2.2.33

Option 1: So you can either use the older version

npm uninstall mongodb --save

npm install [email protected] --save

Option 2: Keep using the newer version (3.0 and above) and modify the code a little bit.

let MongoClient = require('mongodb').MongoClient;
MongoClient.connect('mongodb://localhost:27017', function(err, client){
  if(err) throw err;
  let db = client.db('myTestingDb');
  db.collection('customers').find().toArray(function(err, result){
    if(err) throw err;
    console.log(result);
    client.close();
    });
 });

You can post axios data by using FormData() like:

var bodyFormData = new FormData();

And then add the fields to the form you want to send:

bodyFormData.append('userName', 'Fred');

If you are uploading images, you may want to use .append

bodyFormData.append('image', imageFile); 

And then you can use axios post method (You can amend it accordingly)

axios({
  method: "post",
  url: "myurl",
  data: bodyFormData,
  headers: { "Content-Type": "multipart/form-data" },
})
  .then(function (response) {
    //handle success
    console.log(response);
  })
  .catch(function (response) {
    //handle error
    console.log(response);
  });

Can't get a .post with 'Content-Type': 'multipart/form-data' to work @ axios/axios

According to the official ReactJs documentation, you need to pass argument in the default format witch is:

P = {} // default for your props
S = {} // default for yout state

interface Component<P = {}, S = {}> extends ComponentLifecycle<P, S> { }

Or to define your own type like below: (just an exp)

interface IProps {
    clients: Readonly<IClientModel[]>;

    onSubmit: (data: IClientModel) => void;
}

interface IState {
   clients: Readonly<IClientModel[]>;
   loading: boolean;
}

class ClientsPage extends React.Component<IProps, IState> {
  // ...
}

Someone's going to post a much better answer than this, but just wanted to make the point that personally I would never store a phone number in any kind of integer field, mainly because:

1. You don't need to do any kind of arithmetic with it, and
2. Sooner or later someone's going to try to (do something like) put brackets around their area code.

In general though, I seem to almost exclusively use:

• INT(11) for anything that is either an ID or references another ID
• DATETIME for time stamps
• VARCHAR(255) for anything guaranteed to be under 255 characters (page titles, names, etc)
• TEXT for pretty much everything else.

Of course there are exceptions, but I find that covers most eventualities.

This answer is quite old. pguardiario's got it.

One site to check out is JSON implementation for Ruby. This site offers a gem you can install for a much faster C extension variant.

With the benchmarks given their documentation page they claim that it is 21.500x faster than ActiveSupport::JSON.decode

The code would be the same as Milan Novota's answer with this gem, but the parsing would just be:

parsed_json = JSON(your_json_string)

For me this solved the problem.

heroku pg:reset DATABASE_URL

heroku run bash
>> Inside heroku bash
cd app_name && rm -rf migrations && cd ..
./manage.py makemigrations app_name
./manage.py migrate

If you need to know which properties are different, use reduce():

_.reduce(a, function(result, value, key) {
    return _.isEqual(value, b[key]) ?
        result : result.concat(key);
}, []);
// ? [ "prop2" ]

You forgot to print the result. What you get is the P in RE(P)L and not the actual printed result.

In Py2.x you should so something like

>>> print "\n".join(['I', 'would', 'expect', 'multiple', 'lines'])
I
would
expect
multiple
lines

and in Py3.X, print is a function, so you should do

print("\n".join(['I', 'would', 'expect', 'multiple', 'lines']))

Now that was the short answer. Your Python Interpreter, which is actually a REPL, always displays the representation of the string rather than the actual displayed output. Representation is what you would get with the repr statement

>>> print repr("\n".join(['I', 'would', 'expect', 'multiple', 'lines']))
'I\nwould\nexpect\nmultiple\nlines'

I had the same problem, but

py -m notebook

worked for me.

IN MS SQL server use the COLLATE clause.

SELECT Column1
FROM Table1
WHERE Column1 COLLATE Latin1_General_CS_AS = 'casesearch'

Adding COLLATE Latin1_General_CS_AS makes the search case sensitive.

Default Collation of the SQL Server installation SQL_Latin1_General_CP1_CI_AS is not case sensitive.

To change the collation of the any column for any table permanently run following query.

ALTER TABLE Table1
ALTER COLUMN Column1 VARCHAR(20)
COLLATE Latin1_General_CS_AS

To know the collation of the column for any table run following Stored Procedure.

EXEC sp_help DatabaseName

These days you can also use the Web API ResizeObserver.

Simple example:

const resizeObserver = new ResizeObserver(() => {
    console.log('size changed');
});

resizeObserver.observe(document.querySelector('#myElement'));

a core dump is usually only made when the Windows kernel crashes (aka blue screen). A servicecrash will most of the times only leave some logging behind (in the event viewer probably).

If it is the bluescreen crash dump you are looking for, look in C:\Windows\Minidump or C:\windows\MEMORY.DMP

If you are manually assembling the XML string use var.ToUniversalTime().ToString("yyyy-MM-dd'T'HH:mm:ss.fffffffZ")); That will output the official XML Date Time format. But you don't have to worry about format if you use the built-in serialization methods.

Below the attached solution work over local machine and server.

     public static string SendMail(string bodyContent)
    {
        string sendMail = "";
        try
        {

            string fromEmail = "[email protected]";
            MailMessage mailMessage = new MailMessage(fromEmail, "[email protected]", "Subject", body);
            mailMessage.IsBodyHtml = true;
            SmtpClient smtpClient = new SmtpClient("smtp.gmail.com", 587);
            smtpClient.EnableSsl = true;
            smtpClient.UseDefaultCredentials = false;
            smtpClient.Credentials = new NetworkCredential(fromEmail, frompassword);
            smtpClient.Send(mailMessage);
        }
        catch (Exception ex)
        {
            sendMail = ex.Message.ToString();
            Console.WriteLine(ex.ToString());
        }
        return sendMail;
    }

In my case it was because of other compile errors. When other errors have been solved this seemingly related error was also removed from the list. Specially the errors at the bottom of the errors list and on pages you have recently changed.

So do not pay attention to this error directly and focus on other errors at first.

If you don't want to use any JPA provider such as OpenJPA or Hibernate, you can just give Apache DbUtils a try.

http://commons.apache.org/proper/commons-dbutils/examples.html

Then your code will look like this:

QueryRunner run = new QueryRunner(dataSource);

// Use the BeanListHandler implementation to convert all
// ResultSet rows into a List of Person JavaBeans.
ResultSetHandler<List<Person>> h = new BeanListHandler<Person>(Person.class);

// Execute the SQL statement and return the results in a List of
// Person objects generated by the BeanListHandler.
List<Person> persons = run.query("SELECT * FROM Person", h);

It is really easy to do a bulk insert in Laravel using Eloquent or the query builder.

You can use the following approach.

$data = [
    ['user_id'=>'Coder 1', 'subject_id'=> 4096],
    ['user_id'=>'Coder 2', 'subject_id'=> 2048],
    //...
];

Model::insert($data); // Eloquent approach
DB::table('table')->insert($data); // Query Builder approach

In your case you already have the data within the $query variable.

The default IsSelected trigger changes 3 properties, Background, Foreground & BorderBrush. If you want to change the border as well as the background, just include this in your style trigger.

<Style TargetType="{x:Type dg:DataGridCell}">
    <Style.Triggers>
        <Trigger Property="dg:DataGridCell.IsSelected" Value="True">
            <Setter Property="Background" Value="#CCDAFF" />
            <Setter Property="BorderBrush" Value="Black" />
        </Trigger>
    </Style.Triggers>
</Style>

you have to add parameter also @zip

 SqlConnection conn = new SqlConnection("Data Source=;Initial Catalog=;Persist Security Info=True;User ID=;Password=");
      conn.Open();
      SqlCommand command = new SqlCommand("Select id from [table1] where name=@zip", conn);
      //
    // Add new SqlParameter to the command.
    //
      command.Parameters.AddWithValue("@zip","india");
      int result = (Int32) (command.ExecuteScalar());
      using (SqlDataReader reader = command.ExecuteReader())
      {
          // iterate your results here
       Console.WriteLine(String.Format("{0}",reader["id"]));

      }
      conn.Close();

The easiest way I have tested just add a <br> as in the following:

<div class="col-sm-6">
    <br><h3><p class="text-center">Some Text</p></h3>
</div>

The only problem is that a extra line break (generated by that <br>) is generated when the screen gets smaller and it stacks. But it is quick and simple.

just made something like this as an exercise in Eloquent JavaScript

function range(start, end, step) {
  var ar = [];
  if (start < end) {
    if (arguments.length == 2) step = 1;
    for (var i = start; i <= end; i += step) {
      ar.push(i);
    }
  }
  else {
    if (arguments.length == 2) step = -1;
    for (var i = start; i >= end; i += step) {
      ar.push(i);
    }
  }
  return ar;
}

Maven Micro-Tip: Get sources and Javadocs

When you're using Maven in an IDE you often find the need for your IDE to resolve source code and Javadocs for your library dependencies. There's an easy way to accomplish that goal.

mvn dependency:sources
mvn dependency:resolve -Dclassifier=javadoc

The first command will attempt to download source code for each of the dependencies in your pom file.

The second command will attempt to download the Javadocs.

Maven is at the mercy of the library packagers here. So some of them won't have source code packaged and many of them won't have Javadocs.

In case you have a lot of dependencies it might also be a good idea to use inclusions/exclusions to get specific artifacts, the following command will for example only download the sources for the dependency with a specific artifactId:

mvn dependency:sources -DincludeArtifactIds=guava

Documentation: https://maven.apache.org/plugins/maven-dependency-plugin/sources-mojo.html

HEAD is short for current branch so git push -u origin HEAD works. Now to avoid this typing everytime I use alias:

git config --global alias.pp 'push -u origin HEAD'

After this, everytime I want to push branch created via git -b branch I can push it using:

git pp

Hope this saves time for someone!

jQuery.load()

$('#summary').load('ajax.php', function() {
  alert('Loaded.');
});

for (char letter = 'a'; letter <= 'z'; letter++)
{
    System.out.println(letter);
}

You can give this a try. I am quite new to the forum but wanted to offer something that worked for me since I've gotten so much help from this site in the past. This is essentially a variation of the above, but I found it simpler.

Just paste this into the Userform_Initialize section of your userform code. Note you must already have a listbox on the userform or have it created dynamically above this code. Also please note the Array is a list of headings (below as "Header1", "Header2" etc. Replace these with your own headings. This code will then set up a heading bar at the top based on the column widths of the list box. Sorry it doesn't scroll - it's fixed labels.

More senior coders - please feel free to comment or improve this.

    Dim Mywidths As String
    Dim Arrwidths, Arrheaders As Variant
    Dim ColCounter, Labelleft As Long
    Dim theLabel As Object                

    [Other code here that you would already have in the Userform_Initialize section]

    Set theLabel = Me.Controls.Add("Forms.Label.1", "Test" & ColCounter, True)
            With theLabel
                    .Left = ListBox1.Left

In reference to the above code
$(this) is the element which as some variable.
click is the event that needs to be performed.
the parameter e is automatically passed from js to your function which holds the value of $(this) value and can be used further in your code to do some operation.

Please remove all jar files of Http from 'libs' folder and add below dependencies in gradle file:

compile 'org.apache.httpcomponents:httpclient:4.5'
compile 'org.apache.httpcomponents:httpcore:4.4.3'

None of the above answers worked for me using git version 1.8.3.msysgit.0 and TortoiseGit 1.8.4.0.

In my particular situation, I have to connect to the remote git repo over HTTPS, using a full blown e-mail address as username. In this situation, wincred did not appear to work.

Using the email address as a part of the repo URL also did not work, as the software seems to be confused by the double appearance of the '@' character in the URL.

I did manage to overcome the problem using winstore. Here is what I did:

• Download winstore from http://gitcredentialstore.codeplex.com/
• Run git-credential-winstore.exe to install it.

This will copy the git-credential-winstore.exe to a local directory and add two lines to your global .gitconfig. You can verify this by examining your global .gitconfig. This is easiest done via right mouse button on a folder, "TortoiseGit > Settings > Git > Edit global .gitconfig". The file should contain two lines like:

    [credential]
        helper = !'C:\\Users\\yourlogin\\AppData\\Roaming\\GitCredStore\\git-credential-winstore.exe'

• No other TortoiseGit settings are needed under "Network" or "Credential". In particular: the "Credential helper" pull down menu under "Credential" will have gone blank as a result of these configuration lines, since TortoiseGit does not recognize the new helper. Do not set the pull down menu to another value or the global .gitconfig will be overwritten with an incorrect value! (*)

You are now ready to go:

• Try to pull from the remote repository. You will notice an authentication popup asking your username and password, the popup should be visually different from the default TortoiseGit popup. This is a good sign and means winstore works. Enter the correct authentication and the pull should succeed.
• Try the same pull again, and your username and password should no longer be asked.

Done! Enjoy your interactions with the remote repo while winstore takes care of the authentication.

(*) Alternatively, if you don't like the blank selection in the TortoiseGit Credential settings helper pull down menu, you can use the "Advanced" option:

• Go to "TortoiseGit > Settings > Credential"
• Select Credential helper "Advanced"
• Click on the "G" (for global) under Helpers

• Enter the Helper path as below. Note: a regular Windows path notation (e.g. "C:\Users...") will not work here, you have to replicate the exact line that installing winstore created in the global .gitconf without the "helper =" bit.

  !'C:\\Users\\yourlogin\\AppData\\Roaming\\GitCredStore\\git-credential-winstore.exe'
  

• Click the "Add New/Save" button

   4) Renaming application name- Refer "A)"**

SOAP (Simple Object Access Protocol) is the communication protocol in the web service scenario.

One benefit of SOAP is that it allowas RPC to execute through a firewall. But to pass through a firewall, you will probably want to use 80. it uses port no.8084 To the firewall, a SOAP conversation on 80 looks like a POST to a web page. However, there are extensions in SOAP which are specifically aimed at the firewall. In the future, it may be that firewalls will be configured to filter SOAP messages. But as of today, most firewalls are SOAP ignorant.

so exclusively open SOAP Port in Firewalls

It is really easy with Google Maps Android API v2

Just copy the example from Developer documentation

(of course you have to init your map first)

GoogleMap map;
 // ... get a map.
 // Add a thin red line from London to New York.
 Polyline line = map.addPolyline(new PolylineOptions()
     .add(new LatLng(51.5, -0.1), new LatLng(40.7, -74.0))
     .width(5)
     .color(Color.RED));

You probably did not init postgres.

If you installed using HomeBrew, the init must be run before anything else becomes usable.

To see the instructions, run brew info postgres

# Create/Upgrade a Database
If this is your first install, create a database with:
     initdb /usr/local/var/postgres -E utf8

To have launchd start postgresql at login:
   ln -sfv /usr/local/opt/postgresql/*.plist ~/Library/LaunchAgents 
Then to load postgresql now:     
   launchctl load ~/Library/LaunchAgents/homebrew.mxcl.postgresql.plist 
Or, if you don't want/need launchctl, you can just run:
    pg_ctl -D /usr/local/var/postgres -l /usr/local/var/postgres/server.log start

Once you have run that, it should say something like:

Success. You can now start the database server using:

postgres -D /usr/local/var/postgres or
pg_ctl -D /usr/local/var/postgres -l logfile start

If you are still having issues, check your firewall. If you use a good one like HandsOff! and it was configured to block traffic, then your page will not see the database.

<a href="javascript:void(0);" (click)="onGoToPage2()">Go to Page 2</a>

Steps:

• host + f, to switch to full screen mode, if not yet,
• host + c, to switch to/out of scaled mode,
• host + f, to switch back normal size, if need,

Tip:

• host key, default to right ctrl, the control button on right part of your keyboard,
• host + c seems only work in fullscreen mode,

For an absolute base URL use this. Works with both HTTP and HTTPS.

new Uri(Request.Url, Url.Content("~"))

This might not really answer the question, but just in case someone just need to quickly send a string value to a function that require a NSArray parameter.

NSArray *data = @[@"The String Value"];

if you need to send more than just 1 string value, you could also use

NSArray *data = @[@"The String Value", @"Second String", @"Third etc"];

then you can send it to the function like below

theFunction(data);

Calendar cal = Calendar.getInstance();
SimpleDateFormat sdf = new SimpleDateFormat("EEE MMM dd HH:mm:ss z yyyy", Locale.ENGLISH);
cal.setTime(sdf.parse("Mon Mar 14 16:02:37 GMT 2011"));// all done

note: set Locale according to your environment/requirement

This can be accomplished using the brand new CSS display: grid (browser support)

HTML:

<div class='container'>
  <label for="dummy1">title for dummy1:</label>
  <input id="dummy1" name="dummy1" value="dummy1">
  <label for="dummy2">longer title for dummy2:</label>
  <input id="dummy2" name="dummy2" value="dummy2">
  <label for="dummy3">even longer title for dummy3:</label>
  <input id="dummy3" name="dummy3" value="dummy3">
</div>

CSS:

.container {
  display: grid;
  grid-template-columns: 1fr 3fr;
}

When using css grid, by default elements are laid out column by column then row by row. The grid-template-columns rule creates two grid columns, one which takes up 1/4 of the total horizontal space and the other which takes up 3/4 of the horizontal space. This creates the desired effect.

JS-FIDDLE

In .NET 2.0, you'll need to use Array.Sort to sort the FileSystemInfos.

Additionally, you can use a Comparer delegate to avoid having to declare a class just for the comparison:

DirectoryInfo dir = new DirectoryInfo(path);
FileSystemInfo[] files = dir.GetFileSystemInfos();

// sort them by creation time
Array.Sort<FileSystemInfo>(files, delegate(FileSystemInfo a, FileSystemInfo b)
                                    {
                                        return a.LastWriteTime.CompareTo(b.LastWriteTime);
                                    });

problem is with dos line ending. Following will convert it for unix

dos2unix file_name

NB: you may need to install dos2unix first with yum install dos2unix

another way to do it is using sed command to search and replace the dos line ending characters to unix format:

$sed -i -e 's/\r$//' your_script.sh

As an unordered collection type, set([8, 1, 6]) is equivalent to set([1, 6, 8]).

While it might be nicer to display the set contents in sorted order, that would make the repr() call more expensive.

Internally, the set type is implemented using a hash table: a hash function is used to separate items into a number of buckets to reduce the number of equality operations needed to check if an item is part of the set.

To produce the repr() output it just outputs the items from each bucket in turn, which is unlikely to be the sorted order.

Methods can only declare local variables. That is why the compiler reports an error when you try to declare it as public.

In the case of local variables you can not use any kind of accessor (public, protected or private).

You should also know what the static keyword means. In method checkYourself, you use the Integer array locations.

The static keyword distinct the elements that are accessible with object creation. Therefore they are not part of the object itself.

public class Test { //Capitalized name for classes are used in Java
   private final init[] locations; //key final mean that, is must be assigned before object is constructed and can not be changed later. 

   public Test(int[] locations) {
      this.locations = locations;//To access to class member, when method argument has the same name use `this` key word. 
   }

   public boolean checkYourSelf(int value) { //This method is accessed only from a object.
      for(int location : locations) {
         if(location == value) {
            return true; //When you use key word return insied of loop you exit from it. In this case you exit also from whole method.
         }
      }
      return false; //Method should be simple and perform one task. So you can get more flexibility. 
   }
   public static int[] locations = {1,2,3};//This is static array that is not part of object, but can be used in it. 

   public static void main(String[] args) { //This is declaration of public method that is not part of create object. It can be accessed from every place.
      Test test = new Test(Test.locations); //We declare variable test, and create new instance (object) of class Test.  
      String result;
      if(test.checkYourSelf(2)) {//We moved outside the string
        result = "Hurray";        
      } else {
        result = "Try again"
      }
      System.out.println(result); //We have only one place where write is done. Easy to change in future.
   } 
}

It can be achieved in 2 steps:

1. Set the status bar color to match to your page background using FlutterStatusbarcolor package
2. Set the status bar buttons' (battery, wifi etc.) colors using the AppBar.brightness property

If you have an AppBar:

  @override
  Widget build(BuildContext context) {
    FlutterStatusbarcolor.setStatusBarColor(Colors.white);
    return Scaffold(
      appBar: AppBar(
        brightness: Brightness.light,
        // Other AppBar properties
      ),
      body: Container()
    );
  }

If you don't want to show the app bar in the page:

  @override
  Widget build(BuildContext context) {
    FlutterStatusbarcolor.setStatusBarColor(Colors.white);
    return Scaffold(
      appBar: AppBar(
        brightness: Brightness.light,
        elevation: 0.0,
        toolbarHeight: 0.0, // Hide the AppBar
      ),
      body: Container()
  }

You will want to use the Type.GetType method.

Here is a very simple example:

using System;
using System.Reflection;

class Program
{
    static void Main()
    {
        Type t = Type.GetType("Foo");
        MethodInfo method 
             = t.GetMethod("Bar", BindingFlags.Static | BindingFlags.Public);

        method.Invoke(null, null);
    }
}

class Foo
{
    public static void Bar()
    {
        Console.WriteLine("Bar");
    }
}

I say simple because it is very easy to find a type this way that is internal to the same assembly. Please see Jon's answer for a more thorough explanation as to what you will need to know about that. Once you have retrieved the type my example shows you how to invoke the method.

I had the same issue. The problem is that pip install tries to use C:\Users(username)\AppData\Local\Temp to unpack. You have to explicitly set those directories to R/W.I still couldn't do it because it was a work laptop and there were some permissions issues with trying to set these directories to R/W. The alternative is to go to your Env Variables, and set both Tmp and Temp to point to a writeable directory such as C:. The installation went fine. I was able to install pip.

The way I stumbled onto this is by not defaulting pip install in my installation. Even though the pip install was failing, the installer was not giving any errors. Removing pip and then trying to manually add it later is what pointed to what was going on.

I want to add my 2 cents. I am far from being a database expert, but I've recently read up a bit on this topic; enough for me to try and give an ELI5. So, here's may layman's explanation.

I understand it as such that an index is like a mini-mirror of your table, pretty much like an associative array. If you feed it with a matching key then you can just jump to that row in one "command".

But if you didn't have that index / array, the query interpreter must use a for-loop to go through all rows and check for a match (the full-table scan).

Having an index has the "downside" of extra storage (for that mini-mirror), in exchange for the "upside" of looking up content faster.

Note that (in dependence of your db engine) creating primary, foreign or unique keys automatically sets up a respective index as well. That same principle is basically why and how those keys work.

Note: "schtasks" (see the other, accepted response) has replaced "at". However, "at" may be of use if the situation calls for compatibility with older versions of Windows that don't have schtasks.

Command-line help for "at":

C:\>at /?
The AT command schedules commands and programs to run on a computer at
a specified time and date. The Schedule service must be running to use
the AT command.

AT [\\computername] [ [id] [/DELETE] | /DELETE [/YES]]
AT [\\computername] time [/INTERACTIVE]
    [ /EVERY:date[,...] | /NEXT:date[,...]] "command"

\\computername     Specifies a remote computer. Commands are scheduled on the
                   local computer if this parameter is omitted.
id                 Is an identification number assigned to a scheduled
                   command.
/delete            Cancels a scheduled command. If id is omitted, all the
                   scheduled commands on the computer are canceled.
/yes               Used with cancel all jobs command when no further
                   confirmation is desired.
time               Specifies the time when command is to run.
/interactive       Allows the job to interact with the desktop of the user
                   who is logged on at the time the job runs.
/every:date[,...]  Runs the command on each specified day(s) of the week or
                   month. If date is omitted, the current day of the month
                   is assumed.
/next:date[,...]   Runs the specified command on the next occurrence of the
                   day (for example, next Thursday).  If date is omitted, the
                   current day of the month is assumed.
"command"          Is the Windows NT command, or batch program to be run.

Marshalling is usually between relatively closely associated processes; serialization does not necessarily have that expectation. So when marshalling data between processes, for example, you may wish to merely send a REFERENCE to potentially expensive data to recover, whereas with serialization, you would wish to save it all, to properly recreate the object(s) when deserialized.

Quick and dirty:

LP == Long Pointer. Just think pointer or char*

C = Const, in this case, I think they mean the character string is a const, not the pointer being const.

STR is string

the T is for a wide character or char (TCHAR) depending on compile options.

So you just have to do this right?:

@echo off
echo text shizzle
echo.
echo pause^>nul (press enter)
pause>nul

REM writing to file
(
echo XD
echo LOL
)>settings.cdb
cls

REM setting the variables out of the file
(
set /p input=
set /p input2=
)<settings.cdb
cls

REM echo'ing the variables
echo variables:
echo %input%
echo %input2%
pause>nul

if %input%==XD goto newecho
DEL settings.cdb
exit

:newecho
cls
echo If you can see this, good job!
DEL settings.cdb
pause>nul
exit

You don't want a string, you really want a JS map of key value pairs. E.g., change:

 data: myDataVar.toString(),

with:

var myKeyVals = { A1984 : 1, A9873 : 5, A1674 : 2, A8724 : 1, A3574 : 3, A1165 : 5 }



var saveData = $.ajax({
      type: 'POST',
      url: "someaction.do?action=saveData",
      data: myKeyVals,
      dataType: "text",
      success: function(resultData) { alert("Save Complete") }
});
saveData.error(function() { alert("Something went wrong"); });

jQuery understands key value pairs like that, it does NOT understand a big string. It passes it simply as a string.

UPDATE: Code fixed.

I ran into this as well, but in the case where I wanted to avoid the extra error messages while keeping the range provided. An option is also to subset the data prior to setting the range, so that the range can be kept however you like without triggering warnings.

library(ggplot2)

range(mtcars$hp)
#> [1]  52 335

# Setting limits with scale_y_continous (or ylim) and subsetting accordingly
## avoid warning messages about removing data
ggplot(data= subset(mtcars, hp<=300 & hp >= 100), aes(mpg, hp)) + 
  geom_point() +
  scale_y_continuous(limits=c(100,300))

You could use np.array(list(result.items()), dtype=dtype):

import numpy as np
result = {0: 1.1181753789488595, 1: 0.5566080288678394, 2: 0.4718269778030734, 3: 0.48716683119447185, 4: 1.0, 5: 0.1395076201641266, 6: 0.20941558441558442}

names = ['id','data']
formats = ['f8','f8']
dtype = dict(names = names, formats=formats)
array = np.array(list(result.items()), dtype=dtype)

print(repr(array))

yields

array([(0.0, 1.1181753789488595), (1.0, 0.5566080288678394),
       (2.0, 0.4718269778030734), (3.0, 0.48716683119447185), (4.0, 1.0),
       (5.0, 0.1395076201641266), (6.0, 0.20941558441558442)], 
      dtype=[('id', '<f8'), ('data', '<f8')])

If you don't want to create the intermediate list of tuples, list(result.items()), then you could instead use np.fromiter:

In Python2:

array = np.fromiter(result.iteritems(), dtype=dtype, count=len(result))

In Python3:

array = np.fromiter(result.items(), dtype=dtype, count=len(result))

Why using the list [key,val] does not work:

By the way, your attempt,

numpy.array([[key,val] for (key,val) in result.iteritems()],dtype)

was very close to working. If you change the list [key, val] to the tuple (key, val), then it would have worked. Of course,

numpy.array([(key,val) for (key,val) in result.iteritems()], dtype)

is the same thing as

numpy.array(result.items(), dtype)

in Python2, or

numpy.array(list(result.items()), dtype)

in Python3.

np.array treats lists differently than tuples: Robert Kern explains:

As a rule, tuples are considered "scalar" records and lists are recursed upon. This rule helps numpy.array() figure out which sequences are records and which are other sequences to be recursed upon; i.e. which sequences create another dimension and which are the atomic elements.

Since (0.0, 1.1181753789488595) is considered one of those atomic elements, it should be a tuple, not a list.

Honestly, this doesn't need to be difficult. It may seem that on the onset, but it's not. Here's a simple linq query in C# that does exactly as requested.

In my example, I'm working against a list of persons that have one property called FirstName.

var results = ClientsRepository().Where(c => c.FirstName.ToLower().Contains(searchText.ToLower())).ToList();

This will search the database on lower case search but return full case results.

Try this:

curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);

geocoder.geocode( { 'address': address}, function(results, status) {
    if (status == google.maps.GeocoderStatus.OK) {
      map.setCenter(results[0].geometry.location);
      var marker = new google.maps.Marker({
          map: map,
          position: results[0].geometry.location
      });
    } else {
      alert('Geocode was not successful for the following reason: ' + status);
    }
  });

This is a good article about the subject.

To summarize,

1. Managed code is not compiled to machine code but to an intermediate language which is interpreted and executed by some service on a machine and is therefore operating within a (hopefully!) secure framework which handles dangerous things like memory and threads for you. In modern usage this frequently means .NET but does not have to.

An application program that is executed within a runtime engine installed in the same machine. The application cannot run without it. The runtime environment provides the general library of software routines that the program uses and typically performs memory management. It may also provide just-in-time (JIT) conversion from source code to executable code or from an intermediate language to executable code. Java, Visual Basic and .NET's Common Language Runtime (CLR) are examples of runtime engines. (Read more)

2. Unmanaged code is compiled to machine code and therefore executed by the OS directly. It therefore has the ability to do damaging/powerful things Managed code does not. This is how everything used to work, so typically it's associated with old stuff like .dlls.

An executable program that runs by itself. Launched from the operating system, the program calls upon and uses the software routines in the operating system, but does not require another software system to be used. Assembly language programs that have been assembled into machine language and C/C++ programs compiled into machine language for a particular platform are examples of unmanaged code.(Read more)

3. Native code is often synonymous with Unmanaged, but is not identical.

FIRST, if you want to be able to access man1.py from man1test.py AND manModules.py from man1.py, you need to properly setup your files as packages and modules.

Packages are a way of structuring Python’s module namespace by using “dotted module names”. For example, the module name A.B designates a submodule named B in a package named A.

...

When importing the package, Python searches through the directories on sys.path looking for the package subdirectory.

The __init__.py files are required to make Python treat the directories as containing packages; this is done to prevent directories with a common name, such as string, from unintentionally hiding valid modules that occur later on the module search path.

You need to set it up to something like this:

man
|- __init__.py
|- Mans
   |- __init__.py
   |- man1.py
|- MansTest
   |- __init.__.py
   |- SoftLib
      |- Soft
         |- __init__.py
         |- SoftWork
            |- __init__.py
            |- manModules.py
      |- Unittests
         |- __init__.py
         |- man1test.py

SECOND, for the "ModuleNotFoundError: No module named 'Soft'" error caused by from ...Mans import man1 in man1test.py, the documented solution to that is to add man1.py to sys.path since Mans is outside the MansTest package. See The Module Search Path from the Python documentation. But if you don't want to modify sys.path directly, you can also modify PYTHONPATH:

sys.path is initialized from these locations:

• The directory containing the input script (or the current directory when no file is specified).
• PYTHONPATH (a list of directory names, with the same syntax as the shell variable PATH).
• The installation-dependent default.

THIRD, for from ...MansTest.SoftLib import Soft which you said "was to facilitate the aforementioned import statement in man1.py", that's now how imports work. If you want to import Soft.SoftLib in man1.py, you have to setup man1.py to find Soft.SoftLib and import it there directly.

With that said, here's how I got it to work.

man1.py:

from Soft.SoftWork.manModules import *
# no change to import statement but need to add Soft to PYTHONPATH

def foo():
    print("called foo in man1.py")
    print("foo call module1 from manModules: " + module1())

man1test.py

# no need for "from ...MansTest.SoftLib import Soft" to facilitate importing..
from ...Mans import man1

man1.foo()

manModules.py

def module1():
    return "module1 in manModules"

Terminal output:

$ python3 -m man.MansTest.Unittests.man1test
Traceback (most recent call last):
  ...
    from ...Mans import man1
  File "/temp/man/Mans/man1.py", line 2, in <module>
    from Soft.SoftWork.manModules import *
ModuleNotFoundError: No module named 'Soft'

$ PYTHONPATH=$PYTHONPATH:/temp/man/MansTest/SoftLib
$ export PYTHONPATH
$ echo $PYTHONPATH
:/temp/man/MansTest/SoftLib
$ python3 -m man.MansTest.Unittests.man1test
called foo in man1.py
foo called module1 from manModules: module1 in manModules 

As a suggestion, maybe re-think the purpose of those SoftLib files. Is it some sort of "bridge" between man1.py and man1test.py? The way your files are setup right now, I don't think it's going to work as you expect it to be. Also, it's a bit confusing for the code-under-test (man1.py) to be importing stuff from under the test folder (MansTest).

You need to take out the $ signs before the row numbers in the formula....and the row number used in the formula should correspond to the first row of data, so if you are applying this to the ("applies to") range $B$2:$B$5 it must be this formula

=$B2>$C2

by using that "relative" version rather than your "absolute" one Excel (implicitly) adjusts the formula for each row in the range, as if you were copying the formula down

Thanks Jason Rogers's answer first.

In Android && cpp should be this:

const char *nativeString = env->GetStringUTFChars(javaString, nullptr);

// use your string

env->ReleaseStringUTFChars(javaString, nativeString);

Can fix this errors:

1.error: base operand of '->' has non-pointer type 'JNIEnv {aka _JNIEnv}'

2.error: no matching function for call to '_JNIEnv::GetStringUTFChars(JNIEnv*&, _jstring*&, bool)'

3.error: no matching function for call to '_JNIEnv::ReleaseStringUTFChars(JNIEnv*&, _jstring*&, char const*&)'

4.add "env->DeleteLocalRef(nativeString);" at end.

Here's a nice trick to read JSON from s3:

import json, boto3
s3 = boto3.resource("s3").Bucket("bucket")
json.load_s3 = lambda f: json.load(s3.Object(key=f).get()["Body"])
json.dump_s3 = lambda obj, f: s3.Object(key=f).put(Body=json.dumps(obj))

Now you can use json.load_s3 and json.dump_s3 with the same API as load and dump

data = {"test":0}
json.dump_s3(data, "key") # saves json to s3://bucket/key
data = json.load_s3("key") # read json from s3://bucket/key

I think a more elegant solution is to use the controller and the ViewData dictionary:

//Controller:
public ActionResult Action(int IFRAME)
    {
        ViewData["IsIframe"] = IFRAME == 1;
        return View();
    }

//view
@{
    string classToUse = (bool)ViewData["IsIframe"] ? "iframe-page" : "";
   <div id="wrap" class='@classToUse'></div>
 }

Moved from the closed topic

del /s d:\test\archive*.txt

This should get you all of your text files

Alternatively,

I modified a script I already wrote to look for certain files to move them, this one should go and find files and delete them. It allows you to just choose to which folder by a selection screen.

Please test this on your system before using it though.

If you change the

    * @return the FXML file name
    */
   public abstract String getFileName();

   /**
    * Load FXML, set its controller with given {@code Provider}, and add it to {@code Stage}.
    */
   public void loadView() {
      try {
         FXMLLoader loader = new FXMLLoader(getClass().getClassLoader().getResource(getFileName()));
         loader.setControllerFactory(p -> mProvider.get());
         Node view = loader.load();
         setViewInStage(view);
      }
      catch (IOException ex) {
         LOGGER.error("Failed to load FXML: " + getFileName(), ex);
      }
   }

   private void setViewInStage(Node view) {
      BorderPane pane = (BorderPane)mStage.getScene().getRoot();
      pane.setCenter(view);
   }

   private static final Logger LOGGER = Logger.getLogger(GuiceFxmlLoader.class);

   private final Stage mStage;
   private final Provider<?> mProvider;
}

Here is a concrete implementation of the loader:

public class ConcreteViewLoader extends GuiceFxmlLoader {

   @Inject
   public ConcreteViewLoader(Stage stage, Provider<MyController> provider) {
      super(stage, provider);
   }

   @Override
   public String getFileName() {
      return "my_view.fxml";
   }
}

Note this example loads the view into the center of a BoarderPane that is the root of the Scene in the Stage. This is irrelevant to the example (implementation detail of my specific use case) but decided to leave it in as some may find it useful.

you can also use $rootScope to call a function/method of 1st controller from second controller like this,

.controller('ctrl1', function($rootScope, $scope) {
     $rootScope.methodOf2ndCtrl();
     //Your code here. 
})

.controller('ctrl2', function($rootScope, $scope) {
     $rootScope.methodOf2ndCtrl = function() {
     //Your code here. 
}
})

I know that are already many answers written for this solution however I want to show another javascript method (dependent on JQuery) in which you simply need to include ONLY a single JS File without any dependency on CSS or Gif Images in your code and that will take care of all progress bar related animations that happens during Ajax Request. You need to simnply pass javascript function like this

var objGlobalEvent = new RegisterGlobalEvents(true, "");

Here is the working fiddle for the code. https://jsfiddle.net/vibs2006/c7wukc41/3/

You can use pandas.cut:

bins = [0, 1, 5, 10, 25, 50, 100]
df['binned'] = pd.cut(df['percentage'], bins)
print (df)
   percentage     binned
0       46.50   (25, 50]
1       44.20   (25, 50]
2      100.00  (50, 100]
3       42.12   (25, 50]

bins = [0, 1, 5, 10, 25, 50, 100]
labels = [1,2,3,4,5,6]
df['binned'] = pd.cut(df['percentage'], bins=bins, labels=labels)
print (df)
   percentage binned
0       46.50      5
1       44.20      5
2      100.00      6
3       42.12      5

Or numpy.searchsorted:

bins = [0, 1, 5, 10, 25, 50, 100]
df['binned'] = np.searchsorted(bins, df['percentage'].values)
print (df)
   percentage  binned
0       46.50       5
1       44.20       5
2      100.00       6
3       42.12       5

...and then value_counts or groupby and aggregate size:

s = pd.cut(df['percentage'], bins=bins).value_counts()
print (s)
(25, 50]     3
(50, 100]    1
(10, 25]     0
(5, 10]      0
(1, 5]       0
(0, 1]       0
Name: percentage, dtype: int64

s = df.groupby(pd.cut(df['percentage'], bins=bins)).size()
print (s)
percentage
(0, 1]       0
(1, 5]       0
(5, 10]      0
(10, 25]     0
(25, 50]     3
(50, 100]    1
dtype: int64

By default cut return categorical.

Series methods like Series.value_counts() will use all categories, even if some categories are not present in the data, operations in categorical.

Not directly. But you can use extensions such as LESS to help you achieve the same.

            //do processing
            $(this).attr("label", $(this).text()).text("loading ....").animate({ disabled: true }, 1000, function () {
                //original event call
                $.when($(elm).delay(1000).one("click")).done(function () {//processing finalized
                    $(this).text($(this).attr("label")).animate({ disabled: false }, 1000, function () {
                    })
                });
            });

What's the difference between an RDD's map and mapPartitions method?

The method map converts each element of the source RDD into a single element of the result RDD by applying a function. mapPartitions converts each partition of the source RDD into multiple elements of the result (possibly none).

And does flatMap behave like map or like mapPartitions?

Neither, flatMap works on a single element (as map) and produces multiple elements of the result (as mapPartitions).

In addition to the points from prior answers, it's worth clarifying the differences between these two products from the perspective of choices made in their development.

Sublime is binary compiled for the platform. Its core is written in C/C++ and a number of its features are implemented in Python, which is also the language used for extending it. Atom is written in Node.js/Coffeescript and runs under webkit, with Coffeescript being the extension language. Though similar in UI and UX, Sublime performs significantly better than Atom especially in "heavy lifting" like working with large files, complex SnR or plugins that do heavy processing on files/buffers. Though I expect improvements in Atom as it matures, design & platform choices limit performance.

The "closed" part of Sublime includes the API and UI. Apart from skins/themes and colourisers, the API currently makes it difficult to modify other aspects of the UI. For example, Sublime plugins can't interact with the sidebar, control or draw on the editing area (except in some limited ways eg. in the gutter) or manipulate the statusbar beyond basic text. Atom's "closed" part is unknown at the moment, but I get the sense it's smaller. Atom has a richer API (though poorly documented at present) with the design goal of allowing greater control of its UI. Being closely coupled with webkit offers numerous capabilities for UI feature enhancements not presently possible with Sublime. However, Sublime's extensions perform closer to native, so those that perform compute-intensive, highly repetitive or complex text manipulations in large buffers are feasible in Sublime.

Since more of Atom will be open, Github open-sourced Atom on May 6th. As a result it's likely that support and pace of development will be rapid. By contrast, Sublime's development has slowed significantly of late - but it's not dead. In particular there are a number of bugs, many quite trivial, that haven't been fixed by the developer. None are showstopping imo, but if you want something in rapid development with regular bugfixing and enhancements, Sublime will frustrate. That said, installable Atom packages for Windows and Linux are yet to be released and activity on the codebase seems to have cooled in the weeks before and since the announcement, according to Github's stats.

In terms of IDE functions, from a webdev perspective Atom will allow extensions to the point of approaching products like Webstorm, though none have appeared yet. It remains to be seen how Atom will perform with such "heavy" extensions, since the editor natively feels sluggish. Due to restrictions in the API and lack of underlying webkit, Sublime won't allow this level of UI customisation although the developer may extend the API to support such features in future. Again, Sublime's underlying performance allows for things that involve computational grunt; ST3's symbol indexing being an example that performs well even with big projects. And though Atom's UI is certainly modelled upon Sublime, some refinements are noticeably missing, such as Sublime's learning panels and tab-complete popups which weight the defaults in accordance with those you most use.

I see these products as complementary. The fact that they share similar visuals and keystrokes just adds to the fact. There will be situations where the use of either has advantages. Presently, Sublime is a mature product with feature parity across all three platforms, and a rich set of plugins. Atom is the new kid whose features will rapidly grow; it doesn't feel production ready just yet and there are concerns in the area of performance.

[Update/Edit: May 18, 2015]

A note about improvements to these two editors since the time of writing the above.

In addition to bugfixes and improvements to its core, Atom has experienced a rapid growth in third-party extensions, with autocomplete-plus becoming part of the standard Atom distribution. Extension quality varies widely and a particular irritation is the frequency by which unstable third party packages can crash the editor. Within the last year, Atom has moved to using React by way of shifting reflow/repaint activity to the GPU for performance reasons, significantly improving the responsiveness of the UI for typical editing actions (scrolling, cursor movement etc.). While this has markedly improved the feel of the editor, it still feels cumbersome for CPU intensive tasks as described above, and is still slow in startup. Apart from performance improvements, Atom feels significantly more stable across the board.

Development of Sublime has picked up again since Jan 2015, with bugfixes, some minor new features (tooltip API, build system improvements) and a major development in the form of a new yaml-based .sublime-syntax definition (to eventually replace the old xml .tmLanguage). Together with a custom regex engine which replaces Onigurama, the new system offers more potential for precise regex matching, is significantly faster (up to 4x) and can perform multiple matches in parallel. Apart from colouring syntax, Sublime uses these components for symbol indexing (goto definition etc.) and other language-aware features. In addition to further speeding up Sublime, particularly for large files, this feature should open up the potential for performant language-specific features such as code-refactoring etc.. Further 'big developments' are promised, though the author remains, as ever, tight lipped about them.

Was the fix for me in MVC 4.

Goto File -> Settings -> Compiler now check use external build

then rebuild project

In case someone wanted an example using variables...

#!/bin/bash

# Only continue for 'develop' or 'release/*' branches
BRANCH_REGEX="^(develop$|release//*)"

if [[ $BRANCH =~ $BRANCH_REGEX ]];
then
    echo "BRANCH '$BRANCH' matches BRANCH_REGEX '$BRANCH_REGEX'"
else
    echo "BRANCH '$BRANCH' DOES NOT MATCH BRANCH_REGEX '$BRANCH_REGEX'"
fi

Another way is,

mysql > SHOW CREATE TABLE my_db.my_table;

You should get the table name and create table sql

It is fairly easy to understand. The "-1" stands for "unknown dimension" which can should be infered from another dimension. In this case, if you set your matrix like this:

a = numpy.matrix([[1, 2, 3, 4], [5, 6, 7, 8]])

Modify your matrix like this:

b = numpy.reshape(a, -1)

It will call some deafult operations to the matrix a, which will return a 1-d numpy array/martrix.

However, I don't think it is a good idea to use code like this. Why not try:

b = a.reshape(1,-1)

It will give you the same result and it's more clear for readers to understand: Set b as another shape of a. For a, we don't how much columns it should have(set it to -1!), but we want a 1-dimension array(set the first parameter to 1!).

Use

ftp -s:FileName 

as decribed in Windows XP Professional Product Documentation.

The file name that you have to specify in place of FileName must contain FTP commands that you want to send to the server. Among theses commands are

• open Computer [Port] to connect to an FTP server,
• user UserName [Password] [Account] to authenticate with the FTP server,
• get RemoteFile [LocalFile] to retrieve a file,
• quit to end the FTP session and terminate the ftp program.

More commands can be found under Ftp subcommands.

ADDENDUM: For Windows 8 this will not work; see this excellent answer instead.

Found this solution here: http://www.robvanderwoude.com/clevertricks.php

AT > NUL
IF %ERRORLEVEL% EQU 0 (
    ECHO you are Administrator
) ELSE (
    ECHO you are NOT Administrator. Exiting...
    PING 127.0.0.1 > NUL 2>&1
    EXIT /B 1
)

Assuming that doesn't work and since we're talking Win7 you could use the following in Powershell if that's suitable:

$principal = new-object System.Security.Principal.WindowsPrincipal([System.Security.Principal.WindowsIdentity]::GetCurrent())
$principal.IsInRole([System.Security.Principal.WindowsBuiltInRole]::Administrator)

If not (and probably not, since you explicitly proposed batch files) then you could write the above in .NET and return an exit code from an exe based on the result for your batch file to use.

CMake favours passing the full path to link libraries, so assuming libbingitup.a is in ${CMAKE_SOURCE_DIR}, doing the following should succeed:

add_executable(main main.cpp)
target_link_libraries(main ${CMAKE_SOURCE_DIR}/libbingitup.a)

I've found out the solution! Thanks to Firebug ;)

//"markers" is an array that I declared which contains all the marker of the map
//"i" is the index of the marker in the array that I want to trigger the OnClick event

//V2 version is:
GEvent.trigger(markers[i], 'click');

//V3 version is:
google.maps.event.trigger(markers[i], 'click');

Be very cautious about git rm .; it might remove more than you want. Of course, you can recover, but it is simpler not to have to do so.

Simplest would be:

git rm modules/welcome/language/english/kaimonokago_lang.php \
       modules/welcome/language/french/kaimonokago_lang.php \
       modules/welcome/language/german/kaimonokago_lang.php \
       modules/welcome/language/norwegian/kaimonokago_lang.php

You can't use shell wildcards because the files don't exist, but you could use (in Bash at least):

git rm modules/welcome/language/{english,french,german,norwegian}/kaimonokago_lang.php

Or consider:

git status | sed -n '/^# *deleted:/s///p' | xargs git rm

This takes the output of git status, doesn't print anything by default (sed -n), but on lines that start # deleted:, it gets rid of the # and the deleted: and prints what is left; xargs gathers up the arguments and provides them to a git rm command. This works for any number of files regardless of similarity (or dissimilarity) in the names.

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

My answer is too late, but it can help others.

I had the same problem, even when I used a form tag.

I solved it by declaring Meta Charset in the header of the page:

<meta charset = "UTF-8" />

To change action value of form dynamically, you can try below code:

below code is if you are opening some dailog box and inside that dailog box you have form and you want to change the action of it. I used Bootstrap dailog box and on opening of that dailog box I am assigning action value to the form.

$('#your-dailog-id').on('show.bs.modal', function (event) {
    var link = $(event.relatedTarget);// Link that triggered the modal
    var cURL= link.data('url');// Extract info from data-* attributes
    $("#delUserform").attr("action", cURL);
});

If you are trying to change the form action on regular page, use below code

$("#yourElementId").change(function() { 
  var action = <generate_action>;
  $("#formId").attr("action", action);
});

You would usually do something like this:

while ( resultSet.next() ) { 
   // Read the next item
   resultSet.getString("columnName");
}

If you want to report an empty set, add a variable counting the items read. If you only need to read a single item, then your code is adequate.

I'm trying to find a method to redirect my request from filter to login page

Don't

You just invoke

chain.doFilter(request, response);

from filter and the normal flow will go ahead.

I don't know how to redirect from servlet

You can use

response.sendRedirect(url);

to redirect from servlet

your maximum, minimum method is right

but you don't print int to console!

and... maybe better location change (maximum, minimum) methods

now (maximum, minimum) methods in the roop. it is need not.. just need one call

i suggest change this code

    for (int i = 0 ; i < array.length; i++ ) {
       int next = input.nextInt();
       // sentineil that will stop loop when 999 is entered
       if (next == 999)
       break;
       array[i] = next;
}
System.out.println("max Value : " + getMaxValue(array));
System.out.println("min Value : " + getMinValue(array));
System.out.println("These are the numbers you have entered.");
printArray(array);

wget is capable of doing what you are asking. Just try the following:

wget -p -k http://www.example.com/

The -p will get you all the required elements to view the site correctly (css, images, etc). The -k will change all links (to include those for CSS & images) to allow you to view the page offline as it appeared online.

From the Wget docs:

‘-k’
‘--convert-links’
After the download is complete, convert the links in the document to make them
suitable for local viewing. This affects not only the visible hyperlinks, but
any part of the document that links to external content, such as embedded images,
links to style sheets, hyperlinks to non-html content, etc.

Each link will be changed in one of the two ways:

    The links to files that have been downloaded by Wget will be changed to refer
    to the file they point to as a relative link.

    Example: if the downloaded file /foo/doc.html links to /bar/img.gif, also
    downloaded, then the link in doc.html will be modified to point to
    ‘../bar/img.gif’. This kind of transformation works reliably for arbitrary
    combinations of directories.

    The links to files that have not been downloaded by Wget will be changed to
    include host name and absolute path of the location they point to.

    Example: if the downloaded file /foo/doc.html links to /bar/img.gif (or to
    ../bar/img.gif), then the link in doc.html will be modified to point to
    http://hostname/bar/img.gif. 

Because of this, local browsing works reliably: if a linked file was downloaded,
the link will refer to its local name; if it was not downloaded, the link will
refer to its full Internet address rather than presenting a broken link. The fact
that the former links are converted to relative links ensures that you can move
the downloaded hierarchy to another directory.

Note that only at the end of the download can Wget know which links have been
downloaded. Because of that, the work done by ‘-k’ will be performed at the end
of all the downloads. 

SELECT product FROM Your_table_name WHERE Product LIKE '%XYZ%';

The above statement will show result from a single table. If you want to add more tables then simply use the UNION statement.

SELECT product FROM Table_name_1 
WHERE Product LIKE '%XYZ%'  
UNION  
SELECT product FROM Table_name_2 
WHERE Product LIKE '%XYZ%'  
UNION  
SELECT product FROM Table_name_3 
WHERE Product LIKE '%XYZ%' 

... and so on

The data containing the date column can be read by using the below code:

data = pd.csv(file_path,parse_dates=[date_column])

Once the data is read by using the above line of code, the column containing the information about the date can be accessed using pd.date_time() like:

pd.date_time(data[date_column], format = '%d/%m/%y')

to change the format of date as per the requirement.

Long winded and convoluted (but bear with me!), here is a class system I made to check if a DB exists and also to create the tables required:

<?php
class Table
{
    public static function Script()
    {
        return "
            CREATE TABLE IF NOT EXISTS `users` ( `id` INT NOT NULL PRIMARY KEY AUTO_INCREMENT );

        ";
    }
}

class Install
{
    #region Private constructor
    private static $link;
    private function __construct()
    {
        static::$link = new mysqli();
        static::$link->real_connect("localhost", "username", "password");
    }
    #endregion

    #region Instantiator
    private static $instance;
    public static function Instance()
    {
        static::$instance = (null === static::$instance ? new self() : static::$instance);
        return static::$instance;
    }
    #endregion

    #region Start Install
    private static $installed;
    public function Start()
    {
        var_dump(static::$installed);
        if (!static::$installed)
        {
            if (!static::$link->select_db("en"))
            {
                static::$link->query("CREATE DATABASE `en`;")? $die = false: $die = true;
                if ($die)
                    return false;
                static::$link->select_db("en");
            }
            else
            {
                static::$link->select_db("en");          
            }
            return static::$installed = static::DatabaseMade();  
        }
        else
        {
            return static::$installed;
        }
    }
    #endregion

    #region Table creator
    private static function CreateTables()
    {
        $tablescript = Table::Script();
        return static::$link->multi_query($tablescript) ? true : false;
    }
    #endregion

    private static function DatabaseMade()
    {
        $created = static::CreateTables();
        if ($created)
        {
            static::$installed = true;
        }
        else
        {
            static::$installed = false;
        }
        return $created;
    }
}

In this you can replace the database name en with any database name you like and also change the creator script to anything at all and (hopefully!) it won't break it. If anyone can improve this, let me know!

Note
If you don't use Visual Studio with PHP tools, don't worry about the regions, they are they for code folding :P

You can use boost::lexical_cast:

#include <iostream>
#include <boost/lexical_cast.hpp>

int main( int argc, char* argv[] ){
std::string s1 = "10";
std::string s2 = "abc";
int i;

   try   {

   }
   catch( boost::bad_lexical_cast & e ){
      std::cout << "Exception caught : " << e.what() << std::endl;
   }

   try   {
      i = boost::lexical_cast<int>( s2 );
   }
   catch( boost::bad_lexical_cast & e ){
      std::cout << "Exception caught : " << e.what() << std::endl;
   }

   return 0;
}

The mipmap folders are for placing your app/launcher icons (which are shown on the homescreen) in only. Any other drawable assets you use should be placed in the relevant drawable folders as before.

According to this Google blogpost:

It’s best practice to place your app icons in mipmap- folders (not the drawable- folders) because they are used at resolutions different from the device’s current density.

When referencing the mipmap- folders ensure you are using the following reference:

android:icon="@mipmap/ic_launcher"

The reason they use a different density is that some launchers actually display the icons larger than they were intended. Because of this, they use the next size up.

I had the same problem. I decided in a very unexpected way. Just opened the command line as an administrator. And then typed:

pip install numpy

This worked for me:

Check your topic list on firebase console.

1. Go to firebase console

2. Click Grow from side menu

3. Click Cloud Messaging

4. Click Send your first message

5. In the notification section, type something for Notification title and Notification text

6. Click Next

7. In target section click Topic

8. Click on Message topic textbox, then you can see your topics (I didn't created topic called android or ios, but I can see those two topics.

9. When you send push notification add this as your condition.

   "condition"=> "'all' in topics || 'android' in topics || 'ios' in topics",

Full body

array(
    "notification"=>array(
        "title"=>"Test",
        "body"=>"Test Body",
    ),
    "condition"=> "'all' in topics || 'android' in topics || 'ios' in topics",
);

If you have more topics you can add those with || (or) condition, Then all users will get your notification. Tested and worked for me.

I don't think your question is very clear, this code assumes that if you're going to include the -domain parameter, it's always 'named' (i.e. dostuff computername arg2 -domain domain); this also makes the computername parameter mandatory.

Function DoStuff(){
    param(
        [Parameter(Mandatory=$true)][string]$computername,
        [Parameter(Mandatory=$false)][string]$arg2,
        [Parameter(Mandatory=$false)][string]$domain
    )
    if(!($domain)){
        $domain = 'domain1'
    }
    write-host $domain
    if($arg2){
        write-host "arg2 present... executing script block"
    }
    else{
        write-host "arg2 missing... exiting or whatever"
    }
}

You can use the react-moment package

-> https://www.npmjs.com/package/react-moment

Put in your file the next line:

import moment from "moment";

date_create: moment().format("DD-MM-YYYY hh:mm:ss")

You can test if bool is defined in c99 stdbool.h with

#ifndef __bool_true_false_are_defined || __bool_true_false_are_defined == 0
//typedef or define here
#endif

from collections import OrderedDict
OrderedDict((word, True) for word in words)

contains

OrderedDict([('He', True), ('will', True), ('be', True), ('the', True), ('winner', True)])

If the values are True (or any other immutable object), you can also use:

OrderedDict.fromkeys(words, True)

Every other Object not --> you need to iterate and do a copy by yourself.

To avoid this implement Cloneable.

public class User implements Serializable, Cloneable {

    private static final long serialVersionUID = 1L;

    private String user;
    private String password;
    ...

    @Override
    public Object clone() {
        Object o = null;
        try {
          o = super.clone();
        } catch(CloneNotSupportedException e) {
        }
        return o;
     }
 }

....

  public static void main(String[] args) {

      List<User> userList1 = new ArrayList<User>();

      User user1 = new User();
      user1.setUser("User1");
      user1.setPassword("pass1");
      ...

      User user2 = new User();
      user2.setUser("User2");
      user2.setPassword("pass2");
      ...

      userList1 .add(user1);
      userList1 .add(user2);

      List<User> userList2 = new ArrayList<User>();


      for(User u: userList1){
          u.add((User)u.clone());
      }

      //With this you can avoid 
      /*
        for(User u: userList1){
            User tmp = new User();
            tmp.setUser(u.getUser);
            tmp.setPassword(u.getPassword);
            ...
            u.add(tmp);               
        }
       */

Octave and matlab have many similarities. But Octave is a command line interface. You have to type each command in the command prompt, while matlab comes with best GUI. I recommend first you use matlab student version; after learning basic lessons use gnu octave permentaly. Now gnu octave comes with gui, but it is a development version now. There are some gui front end for gnu octave, like guioctave, xoctave(not free), DomainMath IDE,etc.

Yes. There is a simple way to remove everything in iPython. In iPython console, just type:

%reset

Then system will ask you to confirm. Press y. If you don't want to see this prompt, simply type:

%reset -f

This should work..

The next expression does the job and also works for symbols, not only letters.

The expression works as follows:

1: it uses lapply on the columns of the dataframe q.data to iterate over the rows of the column 2 ("lapply(q.data[,2],"),

2: it apply to each row of the column 2 a function "function(x){sum('a' == strsplit(as.character(x), '')[[1]])}". The function takes each row value of column 2 (x), convert to character (in case it is a factor for example), and it does the split of the string on every character ("strsplit(as.character(x), '')"). As a result we have a a vector with each character of the string value for each row of the column 2.

3: Each vector value of the vector is compared with the desired character to be counted, in this case "a" (" 'a' == "). This operation will return a vector of True and False values "c(True,False,True,....)", being True when the value in the vector matches the desired character to be counted.

4: The total times the character 'a' appears in the row is calculated as the sum of all the 'True' values in the vector "sum(....)".

5: Then it is applied the "unlist" function to unpack the result of the "lapply" function and assign it to a new column in the dataframe ("q.data$number.of.a<-unlist(....")

q.data$number.of.a<-unlist(lapply(q.data[,2],function(x){sum('a' == strsplit(as.character(x), '')[[1]])}))

>q.data

#  number     string     number.of.a
#1   greatgreat         2
#2      magic           1
#3      not             0

SHIFT + Page Up and SHIFT + Page Down are the correct keys to operate on the linux (virtual) console, but vmware console doesn't have those terminal settings. The virtual console has fixed scroll back size, it sounds like it's limited to video memory size according to this Linux virtual console Scrolling behavior documentation.

This is probably an edge case, but every time I've got this specific error it is because I've recently mapped a drive in Windows, and powershell cannot find it.

A computer restart (of all things) fixes the error for me, as powershell can now pick up the newly mapped drive. Just make sure you connect to the mapped drive BEFORE opening the github client.

Use subDays() method:

$users = Users::where('status_id', 'active')
           ->where( 'created_at', '>', Carbon::now()->subDays(30))
           ->get();

The obj directory is for intermediate object files and other transient data files that are generated by the compiler or build system during a build. The bin directory is the directory that final output binaries (and any dependencies or other deployable files) will be written to.

You can change the actual directories used for both purposes within the project settings, if you like.

you need to simply add /Y

xcopy /s c:\mmyinbox\test.doc C:\myoutbox /Y

and if you're using path with spaces, try this

xcopy /s "c:\mmyinbox\test.doc" "C:\myoutbox" /Y

g++ -lboost_system -lboost_filesystem userentry.cpp -o userentry

worked perfectly under debian. (boost c++ libraries installed with apt-get).

I had this problem, then I did:

gem install bundle

notice "bundle" not "bundler" solved my problem.

then in your project folder do:

bundle install

and then you can run your project using:

script/rails server

Here is my observation. I created a login (readonly) for a group windows(AD) user account but, its acting defiantly in different SQL servers. In the SQl servers that users can not see the databases I added view definition checked and also gave database execute permeation to the master database for avoiding error 229. I do not have this issue if I create a login for a user.

Try Using JOptionPane or Swt Shell .

you can simply use this

 startActivity(new Intent(this, Splash.class));
 moveTaskToBack(true);

The startActivity(new Intent(this, Splash.class)); is the first class that will be lauched when the application starts

moveTaskToBack(true); will minimize your application

Simplest solution: You're probably running out of virtual address space (any other form of error usually means running really slowly for a long time before you finally get a MemoryError). This is because a 32 bit application on Windows (and most OSes) is limited to 2 GB of user mode address space (Windows can be tweaked to make it 3 GB, but that's still a low cap). You've got 8 GB of RAM, but your program can't use (at least) 3/4 of it. Python has a fair amount of per-object overhead (object header, allocation alignment, etc.), odds are the strings alone are using close to a GB of RAM, and that's before you deal with the overhead of the dictionary, the rest of your program, the rest of Python, etc. If memory space fragments enough, and the dictionary needs to grow, it may not have enough contiguous space to reallocate, and you'll get a MemoryError.

Install a 64 bit version of Python (if you can, I'd recommend upgrading to Python 3 for other reasons); it will use more memory, but then, it will have access to a lot more memory space (and more physical RAM as well).

If that's not enough, consider converting to a sqlite3 database (or some other DB), so it naturally spills to disk when the data gets too large for main memory, while still having fairly efficient lookup.

i adapted slightly for better ease of use :)

placed at top of script

NEW_LINE=$'\n'

then to use easily with other variables

variable1="test1"
variable2="test2"

OR to append thank-you William Pursell

DESCRIPTION="$variable1$NEW_LINE"
DESCRIPTION+="$variable2$NEW_LINE"

I use highcharts. They are very interactive (and very fancy I might add). You do have to get a little creative to access data from MySQL database, but if you have a general understanding of JavaScript and PHP, you should have no problems.

This link should satisfy your curiosity.

Basically (forgetting your third example which is bad), the different between 1 and 2 is that 1 allocates space for a pointer to the array.

But in the code, you can manipulate them as pointers all the same -- only thing, you cannot reallocate the second.

Just repair Visual Studio itself from the control panel and that should do the trick!

Great suggestion! Here's my reusable take on it:

public class StreamUtils {

    public static <T> Stream<T> asStream(Iterator<T> sourceIterator) {
        return asStream(sourceIterator, false);
    }

    public static <T> Stream<T> asStream(Iterator<T> sourceIterator, boolean parallel) {
        Iterable<T> iterable = () -> sourceIterator;
        return StreamSupport.stream(iterable.spliterator(), parallel);
    }
}

And usage (make sure to statically import asStream):

List<String> aPrefixedStrings = asStream(sourceIterator)
                .filter(t -> t.startsWith("A"))
                .collect(toList());

<a class="btn btn-large btn-success" id="fire" href="http://twitter.github.io/bootstrap/examples/marketing-narrow.html#">Send Email</a>

$('#fire').on('click', function (e) {

     //your awesome code here

})

Try writting the lambda with the same conditions as the delegate. like this:

  List<AnalysisObject> analysisObjects = 
    analysisObjectRepository.FindAll().Where(
    (x => 
       (x.ID == packageId)
    || (x.Parent != null && x.Parent.ID == packageId)
    || (x.Parent != null && x.Parent.Parent != null && x.Parent.Parent.ID == packageId)
    ).ToList();

This one worked for me:

ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;

That's what have worked for me, I wanted to commit only one Cordova plugin to the repo:

try to set the transparency with the android-studio designer in activity_main.xml. If you want it to be transparent, write it for example like this for white: White: #FFFFFF, with 50% transparency: #80FFFFFF This is for Kotlin tho, not sure if that will work the same way for basic android (java).

If you want to check the total line of all the files in a directory ,you can use find and wc:

find . -type f -exec wc -l {} +

Another approach would be to leverage the INSERT ALL syntax from oracle,

INSERT ALL 
    INTO table1(email, campaign_id) VALUES (email, campaign_id)
WITH source_data AS
 (SELECT '[email protected]' email,100 campaign_id
  FROM   dual
  UNION ALL
  SELECT '[email protected]' email,200 campaign_id
  FROM   dual)      
SELECT email
      ,campaign_id
FROM   source_data src
WHERE  NOT EXISTS (SELECT 1
        FROM   table1 dest
        WHERE  src.email = dest.email
        AND    src.campaign_id = dest.campaign_id);

INSERT ALL also allow us to perform a conditional insert into multiple tables based on a sub query as source.

There are some really clean and nice examples are there to refer.

Here's a simple function. It generates a data frame and automatically uses the names of the vectors as values for the first column.

myfunc <- function(a, b, names = NULL) {
  setNames(data.frame(c(rep(deparse(substitute(a)), length(a)), 
                        rep(deparse(substitute(b)), length(b))), c(a, b)), names)
}

An example:

x <-c(1,2,3)
y <-c(100,200,300)
x_name <- "cond"
y_name <- "rating"

myfunc(x, y, c(x_name, y_name))

  cond rating
1    x      1
2    x      2
3    x      3
4    y    100
5    y    200
6    y    300

In past few days my co-workers keep asking me about using AlertDialog in Xamarin.Android and almost all of them sent this question as the ref which they read before asking me (and didn't find the answer), so here is Xamarin.Android (C#) version:

var alertDialog = new AlertDialog.Builder(this) // this: Activity
    .SetTitle("Hello!")
    .SetMessage("Are you sure?")
    .SetPositiveButton("Ok", (sender, e) => { /* ok things */ })
    .SetNegativeButton("Cancel", (sender, e) => { /* cancel things */ })
    .Create();

alertDialog.Show();

// you can customize your AlertDialog, like so
var tvMessage = alertDialog.FindViewById<TextView>(Android.Resource.Id.Message);
tvMessage.TextSize = 13;
// ...

In Netbeans 8 you may have to install the Tomcat plugin manually. After you download and extract Tomcat follow these steps:

1. Tools -> Plugins -> Available plugins, search for 'tomcat' and install the one named "Java EE Base plugin".
2. Restart Netbeans
3. On the project view (default left side of the screen), go to services, right click on Servers and then "Add Server"
4. Select Apache Tomcat, enter username and password and config the rest and finish

When filtering a DataFrame with string values, I find that the pyspark.sql.functions lower and upper come in handy, if your data could have column entries like "foo" and "Foo":

import pyspark.sql.functions as sql_fun
result = source_df.filter(sql_fun.lower(source_df.col_name).contains("foo"))

I did use urlmon.dll in the end. I thought there would be an easier way but this works. I include the code to help anyone else and allow me to find it again if I need it.

using System.Runtime.InteropServices;

...

    [DllImport(@"urlmon.dll", CharSet = CharSet.Auto)]
    private extern static System.UInt32 FindMimeFromData(
        System.UInt32 pBC,
        [MarshalAs(UnmanagedType.LPStr)] System.String pwzUrl,
        [MarshalAs(UnmanagedType.LPArray)] byte[] pBuffer,
        System.UInt32 cbSize,
        [MarshalAs(UnmanagedType.LPStr)] System.String pwzMimeProposed,
        System.UInt32 dwMimeFlags,
        out System.UInt32 ppwzMimeOut,
        System.UInt32 dwReserverd
    );

    public static string getMimeFromFile(string filename)
    {
        if (!File.Exists(filename))
            throw new FileNotFoundException(filename + " not found");

        byte[] buffer = new byte[256];
        using (FileStream fs = new FileStream(filename, FileMode.Open))
        {
            if (fs.Length >= 256)
                fs.Read(buffer, 0, 256);
            else
                fs.Read(buffer, 0, (int)fs.Length);
        }
        try
        {
            System.UInt32 mimetype;
            FindMimeFromData(0, null, buffer, 256, null, 0, out mimetype, 0);
            System.IntPtr mimeTypePtr = new IntPtr(mimetype);
            string mime = Marshal.PtrToStringUni(mimeTypePtr);
            Marshal.FreeCoTaskMem(mimeTypePtr);
            return mime;
        }
        catch (Exception e)
        {
            return "unknown/unknown";
        }
    }

Small reminder: the big O notation is used to denote asymptotic complexity (that is, when the size of the problem grows to infinity), and it hides a constant.

This means that between an algorithm in O(n) and one in O(n²), the fastest is not always the first one (though there always exists a value of n such that for problems of size >n, the first algorithm is the fastest).

Note that the hidden constant very much depends on the implementation!

Also, in some cases, the runtime is not a deterministic function of the size n of the input. Take sorting using quick sort for example: the time needed to sort an array of n elements is not a constant but depends on the starting configuration of the array.

There are different time complexities:

• Worst case (usually the simplest to figure out, though not always very meaningful)

• Average case (usually much harder to figure out...)

• ...

A good introduction is An Introduction to the Analysis of Algorithms by R. Sedgewick and P. Flajolet.

As you say, premature optimisation is the root of all evil, and (if possible) profiling really should always be used when optimising code. It can even help you determine the complexity of your algorithms.

After much testing, I have verified that the original question is already right; missing just a couple of settings:

• the container_row MUST have position: relative;
• the children (...), MUST have position: absolute; left:0;
• to make sure the children (...) align exactly over each other, the container_row should have additional styling:
  • height:x; line-height:x; vertical-align:middle;
  • text-align:center; could, also, help.

In case you have trouble building boost or prefer not to do that, an alternative is to download the lib files from SourceForge. The link will take you to a folder of zipped lib and dll files for version 1.51. But, you should be able to edit the link to specify the version of choice. Apparently the installer from BoostPro has some issues.

Another method is to expose a web-accessible resource, though this will allow any website to test if your extension is installed.

Suppose your extension's ID is aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa, and you add a file (say, a transparent pixel image) as test.png in your extension's files.

Then, you expose this file to the web pages with web_accessible_resources manifest key:

  "web_accessible_resources": [
    "test.png"
  ],

In your web page, you can try to load this file by its full URL (in an <img> tag, via XHR, or in any other way):

chrome-extension://aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa/test.png

If the file loads, then the extension is installed. If there's an error while loading this file, then the extension is not installed.

// Code from https://groups.google.com/a/chromium.org/d/msg/chromium-extensions/8ArcsWMBaM4/2GKwVOZm1qMJ
function detectExtension(extensionId, callback) { 
  var img; 
  img = new Image(); 
  img.src = "chrome-extension://" + extensionId + "/test.png"; 
  img.onload = function() { 
    callback(true); 
  }; 
  img.onerror = function() { 
    callback(false); 
  };
}

Of note: if there is an error while loading this file, said network stack error will appear in the console with no possibility to silence it. When Chromecast used this method, it caused quite a bit of controversy because of this; with the eventual very ugly solution of simply blacklisting very specific errors from Dev Tools altogether by the Chrome team.

Important note: this method will not work in Firefox WebExtensions. Web-accessible resources inherently expose the extension to fingerprinting, since the URL is predictable by knowing the ID. Firefox decided to close that hole by assigning an instance-specific random URL to web accessible resources:

The files will then be available using a URL like:

moz-extension://<random-UUID>/<path/to/resource>

This UUID is randomly generated for every browser instance and is not your extension's ID. This prevents websites from fingerprinting the extensions a user has installed.

However, while the extension can use runtime.getURL() to obtain this address, you can't hard-code it in your website.

in mvc 5

              @Html.EditorFor(x => x.Address, 
              new {htmlAttributes = new {@class = "form-control", 
                   @placeholder = "Complete Address", @cols = 10, @rows = 10 } })

Posting a java based solution, incase your team only uses java. The keyword inner will ensure that matching rows only are present in the final dataframe.

            Dataset<Row> joined = PersonDf.join(ProfileDf, 
                    PersonDf.col("personId").equalTo(ProfileDf.col("personId")),
                    "inner");
            joined.show();

Hashes are a sequence of bits (128 bits, 160 bits, 256 bits, etc., depending on the algorithm). Your column should be binary-typed, not text/character-typed, if MySQL allows it (SQL Server datatype is binary(n) or varbinary(n)). You should also salt the hashes. Salts may be text or binary, and you will need a corresponding column.

First you need to turn on virtualization on your machine. To do that, restart your machine. Press F2. Goto BIOS. Make Virtualization Enabled. Press F10. Start windows. Now, goto Extras folder of Android installation folder and find intel-haxm-android.exe. Run it. Start Android Studio. Now, it should allow you to run your program using emulator.

Here's an awesome one-liner to update everything to the latest on master:

git submodule foreach 'git fetch origin --tags; git checkout master; git pull' && git pull && git submodule update --init --recursive

Thanks to Mark Jaquith

git log --format="%h" | tail -1 gives you the commit hash (ie 0dd89fb), which you can feed into other commands, by doing something like

git diff `git log --format="%h" --after="1 day"| tail -1`..HEAD to view all the commits in the last day.

To add to @akilat90's update about sklearn.metrics.plot_confusion_matrix:

You can use the ConfusionMatrixDisplay class within sklearn.metrics directly and bypass the need to pass a classifier to plot_confusion_matrix. It also has the display_labels argument, which allows you to specify the labels displayed in the plot as desired.

The constructor for ConfusionMatrixDisplay doesn't provide a way to do much additional customization of the plot, but you can access the matplotlib axes obect via the ax_ attribute after calling its plot() method. I've added a second example showing this.

I found it annoying to have to rerun a classifier over a large amount of data just to produce the plot with plot_confusion_matrix. I am producing other plots off the predicted data, so I don't want to waste my time re-predicting every time. This was an easy solution to that problem as well.

Example:

from sklearn.metrics import confusion_matrix, ConfusionMatrixDisplay

cm = confusion_matrix(y_true, y_preds, normalize='all')
cmd = ConfusionMatrixDisplay(cm, display_labels=['business','health'])
cmd.plot()

Example using ax_:

cm = confusion_matrix(y_true, y_preds, normalize='all')
cmd = ConfusionMatrixDisplay(cm, display_labels=['business','health'])
cmd.plot()
cmd.ax_.set(xlabel='Predicted', ylabel='True')

you can for example: set your environment variable path with php.exe folder e.g c:\program files\php

create a script file in d:\ with filename as a.php

open cmd: go to d: drive using d: command

type following command

php -f a.php

you will see the output

You can use .substring, which returns a potion of a string:

"abcdefghijklmnopq".substring(0, 8) === "abcdefgh"; // portion from index 0 to 8

My two cents on Stream. I think it's better to use

IntStream.generate(i -> MyClass.contruct())
         .limit(INT_SIZE)
         .collect(Collectors.toList());

with the flexibility to put any initial values.

Make sure to remove any previous 'localhost' certificates as those could conflict with the one generated by IIS Express. I had this same error (ERR_SSL_PROTOCOL_ERROR), and it took me many hours to finally figure it out after trying out many many "solutions". My mistake was that I had created my own 'localhost' certificate and there were two of them. I had to delete both and have IIS Express recreate it.

Here is how you can check for and remove 'localhost' certificate:

• On Start, type ? mmc.exe
• File ? Add/Remove Snap-in...
• Select Certificates ? Add> ? Computer account ? Local computer
• Check under Certificates > Personal > Certificates
• Make sure the localhost certificate that exist has a friendly name "IIS Express Development Certificate". If not, delete it. Or if multiple, delete all.

On Visual Studio, select project and under property tab, enable SSL=true. Save, Build and Run. IIS Express will generate a new 'localhost' certificate.

Note: If it doesn't work, try these: make sure to disable IIS Express on VS project and stopping all running app on it prior to removing 'localhost' certificate. Also, you can go to 'control panel > programs' and Repair IIS Express.

I always looked at scripting languages as a means to communicate with some sort of application or program. In contrast, a language which is compiled actually creates the program itself.

Now keep in mind that a scripting language usually adds on to or modifies the program that was initially created with a language that was compiled. Thus, it can certainly be part of the larger picture but the initial binaries are first created with a language that is compiled.

So I could create a scripting language which lets users perform various actions or customize my program. My program would interpret the scripted code and in turn call some kind of function. This is just a basic example. It just gives you a way to dynamically call routines within the program.

My program would have to parse the scripted code (you could refer to these as commands) and execute whatever action was intended in real time.

I see this question was already answered several times but I thought I would add my way of looking at things into the mix. Granted, some folks may disagree with this answer but this way of thinking has always helped me.

The AdamOptimizer class creates additional variables, called "slots", to hold values for the "m" and "v" accumulators.

See the source here if you're curious, it's actually quite readable: https://github.com/tensorflow/tensorflow/blob/master/tensorflow/python/training/adam.py#L39 . Other optimizers, such as Momentum and Adagrad use slots too.

These variables must be initialized before you can train a model.

The normal way to initialize variables is to call tf.initialize_all_variables() which adds ops to initialize the variables present in the graph when it is called.

(Aside: unlike its name suggests, initialize_all_variables() does not initialize anything, it only add ops that will initialize the variables when run.)

What you must do is call initialize_all_variables() after you have added the optimizer:

...build your model...
# Add the optimizer
train_op = tf.train.AdamOptimizer(1e-4).minimize(cross_entropy)
# Add the ops to initialize variables.  These will include 
# the optimizer slots added by AdamOptimizer().
init_op = tf.initialize_all_variables()

# launch the graph in a session
sess = tf.Session()
# Actually intialize the variables
sess.run(init_op)
# now train your model
for ...:
  sess.run(train_op)

I've found yet another reason for spy to call the original method.

Someone had the idea to mock a final class, and found about MockMaker:

As this works differently to our current mechanism and this one has different limitations and as we want to gather experience and user feedback, this feature had to be explicitly activated to be available ; it can be done via the mockito extension mechanism by creating the file src/test/resources/mockito-extensions/org.mockito.plugins.MockMaker containing a single line: mock-maker-inline

Source: https://github.com/mockito/mockito/wiki/What%27s-new-in-Mockito-2#mock-the-unmockable-opt-in-mocking-of-final-classesmethods

After I merged and brought that file to my machine, my tests failed.

I just had to remove the line (or the file), and spy() worked.

Instead of instantiating as follows:

TestRestTemplate restTemplate = new TestRestTemplate();

Just do it like this:

TestRestTemplate restTemplate = new TestRestTemplate(user, password);

It works for me, I hope it helps!

It seems to me removeProp is not working properly in Chrome : jsfiddle

        $('#badBut1').click(function () {
        checkit('Before');
        if( $('#chk').prop('checked') )
        {
          $('#chk').removeProp('checked');
        }else{
            $('#chk').prop('checked', true);
        }
        checkit('After');
    });
    $('#But1').click(function () {
        checkit('Before');
        if( $('#chk').prop('checked') )
        {
          $('#chk').removeClass('checked').prop('checked',false);
        }else{
            $('#chk').addClass('checked').prop('checked', true);
        }
        checkit('After');
    });

    $('#But2').click(function () {
        var chk1 = $('#chk').is(':checked');
        console.log("Value : " + chk1);
    });

    $('#chk').on( 'change',function () {
        checkit('Result');
    });
    function checkit(moment) {
        var chk1 = $('#chk').is(':checked');
        console.log(moment+", value = " + chk1);
    };

From JDK8 on words it is as simple as

final File currentDir = new File(YOUR_DIRECTORY_PATH);
File[] files = currentDir.listFiles((File pathname) -> pathname.getName().endsWith(extension));

There are two possible reasons for that error:

1. your jquery script file referencing is not valid

2. try to put your jquery code in document.ready, like this:

You can actually set the timeout interval at the Jetty server side configuration using the WebSocketServletFactory instance. For example:

WebSocketHandler wsHandler = new WebSocketHandler() {
    @Override
    public void configure(WebSocketServletFactory factory) {
        factory.getPolicy().setIdleTimeout(1500);
        factory.register(MyWebSocketAdapter.class);
        ...
    }
}

"start" is a name of a script, in npm you run scripts like this npm run scriptName, npm start is also a short for npm run start

As for "react-scripts" this is a script related specifically to create-react-app

I am in ubuntu 14.04 and mongod is registered as an upstart service. The answers in this post sent me in the right direction. The only adaptation I had to do to make things work with the upstart service was to edit /etc/mongod.conf. Look for the lines that read:

# Enable the HTTP interface (Defaults to port 28017).
# httpinterface = true

Just remove the # in front of httpinterface and restart the mongod service:

sudo restart mongod

Note: You can also enable the rest interface by adding a line that reads rest=true right below the httpinterface line mentioned above.

for using As logout you need to terminate all app from Ram Cache so close The Application first and then Rerun it

//on clicking Logout Button

foreach(Form frm in Application.OpenForms.Cast<Form>().ToList())
        {
            frm.Close();
        }
System.Diagnostics.Process.Start(Application.ExecutablePath);

I was getting the same error when I tried to do :

cordova build ios

except mine said ** ARCHIVE FAILED ** rather than ** BUILD FAILED **.

I fixed it by opening the projectName.xcodeproj file in Xcode and then adjusting these 2 settings :

1. In Targets > General > Signing ensure you have selected a Team

2. In Targets > Build Settings > (search for "bitcode") set Enable Bitcode to "Yes"

Then I quit out of Xcode and reran cordova build ios and it worked.

Answers so far helped me come up with mine. I'm wary of UTC vs local time; ticks should always be UTC IMO.

public class Time
{
    public static void Timestamps()
    {
        OutputTimestamp();
        Thread.Sleep(1000);
        OutputTimestamp();
    }

    private static void OutputTimestamp()
    {
        var timestamp = DateTime.UtcNow.Ticks;
        var localTicks = DateTime.Now.Ticks;
        var localTime = new DateTime(timestamp, DateTimeKind.Utc).ToLocalTime();
        Console.Out.WriteLine("Timestamp = {0}.  Local ticks = {1}.  Local time = {2}.", timestamp, localTicks, localTime);
    }
}

Output:

Timestamp = 636988286338754530.  Local ticks = 636988034338754530.  Local time = 2019-07-15 4:03:53 PM.
Timestamp = 636988286348878736.  Local ticks = 636988034348878736.  Local time = 2019-07-15 4:03:54 PM.

Add the file to a formData object, and set the Content-Type header to multipart/form-data.

var formData = new FormData();
var imagefile = document.querySelector('#file');
formData.append("image", imagefile.files[0]);
axios.post('upload_file', formData, {
    headers: {
      'Content-Type': 'multipart/form-data'
    }
})

Yes you can do that by just creating a BroadcastReceiver that calls your Service when your Application boots. Here is a complete answer given by me.
Android - Start service on boot

If you don't want any icon/launcher for you Application you can do that also, just don't create any Activity with

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

Just declare your Service as declared normally.

I had this problem with only with redirectMode="ResponseRewrite" (redirectMode="ResponseRedirect" worked fine) and none of the above solutions helped my resolve the issue. However, once I changed the server's application pool's "Managed Pipeline Mode" from "Classic" to "Integrated" the custom error page appeared as expected.

Check if port 80 and 443 are blocked. or enter - IP graph.facebook.com and enter it in etc/hosts file

To make your life simpler, you may want to consider using JAX-WS framework such as Apache CXF or Apache Axis2.

EDIT By the way, the Authorization field just uses simple Base64 encoding. According to this ( http://www.motobit.com/util/base64-decoder-encoder.asp ), the decoded value is german:german.

I just ran into a similar issue. Recently started developing on windows, so getting used to the PowerShell. Ironically when trying to use 'conda activate ' in Git-bash i got the error

$ conda activate obf

CommandNotFoundError: Your shell has not been properly configured to use 'conda activate'.
If using 'conda activate' from a batch script, change your
invocation to 'CALL conda.bat activate'.

To initialize your shell, run

    $ conda init <SHELL_NAME>

Currently supported shells are:
  - bash
  - cmd.exe
  - fish
  - tcsh
  - xonsh
  - zsh
  - powershell

See 'conda init --help' for more information and options.

IMPORTANT: You may need to close and restart your shell after running 'conda init'. 

Running the command in my PowerShell (elevated) as instructed did the trick for me.

conda init powershell 

This should be true across all terminal environments, just strange PowerShell didn't return this error itself.

Try this:

<asp:HiddenField ID="0858674_h" Value="0" runat="server" />

var test = $(this).find('[id*="_h"').val();

Yes, require is a Node.JS function and doesn't work in client side scripting without certain requirements. If you're getting this error while writing electronJS code, try the following:

In your BrowserWindow declaration, add the following webPreferences field: i.e, instead of plain mainWindow = new BrowserWindow(), write

mainWindow = new BrowserWindow({
        webPreferences: {
            nodeIntegration: true
        }
    });

Maybe you can try the following :

var i = 0;
function AjaxSendForm(url, placeholder, form, append) {
var data = $(form).serialize();
append = (append === undefined ? false : true); // whatever, it will evaluate to true or false only
$.ajax({
    type: 'POST',
    url: url,
    data: data,
    beforeSend: function() {
        // setting a timeout
        $(placeholder).addClass('loading');
        i++;
    },
    success: function(data) {
        if (append) {
            $(placeholder).append(data);
        } else {
            $(placeholder).html(data);
        }
    },
    error: function(xhr) { // if error occured
        alert("Error occured.please try again");
        $(placeholder).append(xhr.statusText + xhr.responseText);
        $(placeholder).removeClass('loading');
    },
    complete: function() {
        i--;
        if (i <= 0) {
            $(placeholder).removeClass('loading');
        }
    },
    dataType: 'html'
});
}

This way, if the beforeSend statement is called before the complete statement i will be greater than 0 so it will not remove the class. Then only the last call will be able to remove it.

I cannot test it, let me know if it works or not.

its very simple

just write:

//first create table named test....

create table test (name varchar2(10),age number(5));

//when you run the above code a table will be created....

//now we have to insert a name & an age..

Make sure age will be inserted via opening a form that seeks our help to enter the value in it

insert into test values('Deepak', :age);

//now run the above code and you'll get "1 row inserted" output...

/now run the select query to see the output

select * from test;

//that's all ..Now i think no one has any queries left over accepting a user data...

Since the column is of type VARCHAR, you should convert the input parameter to a string rather than converting the column value to a number:

select * from exception where exception_value = to_char(105);

A few differences:

1. print vs println:

   The print function prints messages in the Xcode console when debugging apps.

   The println is a variation of this that was removed in Swift 2 and is not used any more. If you see old code that is using println, you can now safely replace it with print.

   Back in Swift 1.x, print did not add newline characters at the end of the printed string, whereas println did. But nowadays, print always adds the newline character at the end of the string, and if you don't want it to do that, supply a terminator parameter of "".

2. NSLog:

   • NSLog adds a timestamp and identifier to the output, whereas print will not;

   • NSLog statements appear in both the device’s console and debugger’s console whereas print only appears in the debugger console.

   • NSLog in iOS 10-13/macOS 10.12-10.x uses printf-style format strings, e.g.

       NSLog("%0.4f", CGFloat.pi)
     

     that will produce:

     2017-06-09 11:57:55.642328-0700 MyApp[28937:1751492] 3.1416

   • NSLog from iOS 14/macOS 11 can use string interpolation. (Then, again, in iOS 14 and macOS 11, we would generally favor Logger over NSLog. See next point.)

   Nowadays, while NSLog still works, we would generally use “unified logging” (see below) rather than NSLog.

3. Effective iOS 14/macOS 11, we have Logger interface to the “unified logging” system. For an introduction to Logger, see WWDC 2020 Explore logging in Swift.

   • To use Logger, you must import os:

     import os
     

   • Like NSLog, unified logging will output messages to both the Xcode debugging console and the device console, too

   • Create a Logger and log a message to it:

     let logger = Logger(subsystem: Bundle.main.bundleIdentifier!, category: "network")
     logger.log("url = \(url)")
     

     When you observe the app via the external Console app, you can filter on the basis of the subsystem and category. It is very useful to differentiate your debugging messages from (a) those generated by other subsystems on behalf of your app, or (b) messages from other categories or types.

   • You can specify different types of logging messages, either .info, .debug, .error, .fault, .critical, .notice, .trace, etc.:

     logger.error("web service did not respond \(error.localizedDescription)")
     

     So, if using the external Console app, you can choose to only see messages of certain categories (e.g. only show debugging messages if you choose “Include Debug Messages” on the Console “Action” menu). These settings also dictate many subtle issues details about whether things are logged to disk or not. See WWDC video for more details.

   • By default, non-numeric data is redacted in the logs. In the example where you logged the URL, if the app were invoked from the device itself and you were watching from your macOS Console app, you would see the following in the macOS Console:

     url = <private>

     If you are confident that this message will not include user confidential data and you wanted to see the strings in your macOS console, you would have to do:

     os_log("url = \(url, privacy: .public)")
     

4. Prior to iOS 14/macOS 11, iOS 10/macOS 10.12 introduced os_log for “unified logging”. For an introduction to unified logging in general, see WWDC 2016 video Unified Logging and Activity Tracing.

   • Import os.log:

     import os.log
     

   • You should define the subsystem and category:

     let log = OSLog(subsystem: Bundle.main.bundleIdentifier!, category: "network")
     

     When using os_log, you would use a printf-style pattern rather than string interpolation:

     os_log("url = %@", log: log, url.absoluteString)
     

   • You can specify different types of logging messages, either .info, .debug, .error, .fault (or .default):

     os_log("web service did not respond", type: .error)
     

   • You cannot use string interpolation when using os_log. For example with print and Logger you do:

     logger.log("url = \(url)")
     

     But with os_log, you would have to do:

     os_log("url = %@", url.absoluteString)
     

   • The os_log enforces the same data privacy, but you specify the public visibility in the printf formatter (e.g. %{public}@ rather than %@). E.g., if you wanted to see it from an external device, you'd have to do:

     os_log("url = %{public}@", url.absoluteString)
     

   • You can also use the “Points of Interest” log if you want to watch ranges of activities from Instruments:

     let pointsOfInterest = OSLog(subsystem: Bundle.main.bundleIdentifier!, category: .pointsOfInterest)
     

     And start a range with:

     os_signpost(.begin, log: pointsOfInterest, name: "Network request")
     

     And end it with:

     os_signpost(.end, log: pointsOfInterest, name: "Network request")
     

     For more information, see https://stackoverflow.com/a/39416673/1271826.

Bottom line, print is sufficient for simple logging with Xcode, but unified logging (whether Logger or os_log) achieves the same thing but offers far greater capabilities.

The power of unified logging comes into stark relief when debugging iOS apps that have to be tested outside of Xcode. For example, when testing background iOS app processes like background fetch, being connected to the Xcode debugger changes the app lifecycle. So, you frequently will want to test on a physical device, running the app from the device itself, not starting the app from Xcode’s debugger. Unified logging lets you still watch your iOS device log statements from the macOS Console app.

The solution was to add these flags to JVM command line when Tomcat is started:

-XX:+CMSClassUnloadingEnabled -XX:+CMSPermGenSweepingEnabled

You can do that by shutting down the tomcat service, then going into the Tomcat/bin directory and running tomcat6w.exe. Under the "Java" tab, add the arguments to the "Java Options" box. Click "OK" and then restart the service.

If you get an error the specified service does not exist as an installed service you should run:

tomcat6w //ES//servicename

where servicename is the name of the server as viewed in services.msc

This works for me. say you have a strings.resx file with string ok in it. to read it

String varOk = My.Resources.strings.ok

If you're feeling lazy, here's a terse method of handling conditions using || (or) and && (and) after the operation:

wget -q --tries=10 --timeout=20 --spider http://google.com || \
{ echo "Sorry you are Offline" && exit 1; }

you can use always:

'C:/mydir'

this works both in linux and windows. Other posibility is

'C:\\mydir'

if you have problems with some names you can also try raw string literals:

r'C:\mydir'

however best practice is to use the os.path module functions that always select the correct configuration for your OS:

os.path.join(mydir, myfile)

From python 3.4 you can also use the pathlib module. This is equivelent to the above:

pathlib.Path(mydir, myfile)

or

pathlib.Path(mydir) / myfile

indentation is important in Python. Your if else statement should be within triple arrow (>>>), In Mac python IDLE version 3.7.4 elif statement doesn't comes with correct indentation when you go on next line you have to shift left to avoid syntax error.

Unfortunately node does not support for each ... in, even though it is specified in JavaScript 1.6. Chrome uses the same JavaScript engine and is reported as having a similar shortcoming.

You'll have to settle for array.forEach(function(item) { /* etc etc */ }).

EDIT: From Google's official V8 website:

V8 implements ECMAScript as specified in ECMA-262.

On the same MDN website where it says that for each ...in is in JavaScript 1.6, it says that it is not in any ECMA version - hence, presumably, its absence from Node.

As of Android Studio 3.0 / Gradle Build Tools 3.0.0, APK artifacts can now be found in foo/bar/build/outputs/apk/flavorName/buildType with respect to your project name, foo, and your module name, bar. There is now a directory for each apk file sorted organized first by flavor (with respect to flavor dimensions) and then by build type.

You need to use gdb's memory-display commands. The basic one is x, for examine. There's an example on the linked-to page that uses

gdb> x/4xw $sp

to print "four words (w ) of memory above the stack pointer (here, $sp) in hexadecimal (x)". The quotation is slightly paraphrased.

I had an issue and fixed it after spending 2 hours to find. My environment as below:

cocoapod 0.39.0

swift 2.x

XCode 7.3.1

Steps:

1. project path: project_name/project_name/your_bridging_header.h
2. In Swift section at Build Setting, Objective-C Bridging Header should be: project_name/your_bridging_header.h
3. In your_bridging_header.h, change all declarations from .h to #import
4. In class which is being used your_3rd_party. Declare import your_3rd_party

You can use requests-html which will download and use chromium underneath.

from requests_html import HTML

html = HTML(html="<a href='http://www.example.com/'>")

script = """
function escramble_758(){
    var a,b,c
    a='+1 '
    b='84-'
    a+='425-'
    b+='7450'
    c='9'
    return a+c+b;
}
"""

val = html.render(script=script, reload=False)
print(val)
# +1 425-984-7450

Service extends ContextWrapper which extends Context. Hence the Service is a Context. Use 'this' keyword in the service.

There are several different ways to achieve this, as shown by the variety of answers on this question.

To actually assign the listener to the view, you use the same methods as you would in Java:

button.setOnClickListener()

However, Kotlin makes it easy to assign a lambda as a listener:

button.onSetClickListener {
    // Listener code
}

Alternatively, if you want to use this listener for multiple views, consider a lambda expression (a lambda assigned to a variable/value for reference):

val buttonClickListener = View.OnClickListener { view ->
    // Listener code
}

button.setOnClickListener(buttonClickListener)
another_button.setOnClickListener(buttonClickListener)

For closing (not quit) the running application in Simulator the keyboard shortcut is "shift+command+h".

For versions prior to 2.5, there's the trick:

[expression] and [on_true] or [on_false]

It can give wrong results when on_true has a false boolean value.¹
Although it does have the benefit of evaluating expressions left to right, which is clearer in my opinion.
