Hardware wise the Quadro and GeForce cards are often idential. Indeed it is sometimes possible to convert some models from GeForce into Quadro by simply uploading new firmware and changing a couple resistor jumpers.

The difference is in the intended market and hence cost.

Quadro cards are intended for CAD. High end CAD software still uses OpenGL, whereas games and lower end CAD software use Direct3D (aka DirectX).

Quadro cards simply have firmware that is optimised for OpenGL. In the early days OpenGL was better and faster than Direct3D but now there is little difference. Gaming cards only support a very limited set of OpenGL, hence they don't run it very well.

CAD companies, e.g. Dassault with SolidWorks actively push high end cards by offering no support for DirectX with any level of performance.

Other CAD companies such as Altium, with Altium Designer, made the decision that forcing their customers to buy more expensive cards is not worthwhile when Direct3D is as good (if not better these days) than OpenGL.

Because of the cost, there are often other differences in the hardware, such as less use of overclocking, more memory etc, but these have relatively minor effects compared with the firmware support.

Try this ..

    txtview.setCompoundDrawablesWithIntrinsicBounds(
                    R.drawable.image, 0, 0, 0);

Also see this.. http://developer.android.com/reference/android/widget/TextView.html

Try this in xml file

    <TextView
        android:id="@+id/txtStatus"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:drawableLeft="@drawable/image"
        android:drawablePadding="5dp"
        android:maxLines="1"
        android:text="@string/name"/>

Empty both your tables' data and run the command. It will work.

You can also throw an exception:

Note:

For the sake of readability each step of stream should be listed in new line.

players.stream()
       .filter(player -> player.getName().contains(name))
       .findFirst()
       .orElseThrow(MyCustomRuntimeException::new);

if your logic is loosely "exception driven" such as there is one place in your code that catches all exceptions and decides what to do next. Only use exception driven development when you can avoid littering your code base with multiples try-catch and throwing these exceptions are for very special cases that you expect them and can be handled properly.)

The most secure solution is to keep your keys on a server and route all requests needing that key through your server. That way the key never leaves your server, so as long as your server is secure then so is your key. Of course there is a performance cost with this solution.

Adding my own experience for those who are experiencing this in the future. My specific error was

Failed to establish a new connection: [Errno 8] nodename nor servname provided, or not known'

It turns out that this was actually because I had reach the maximum number of open files on my system. It had nothing to do with failed connections, or even a DNS error as indicated.

How are you calling the start function?

This should work (new is the key)

var o = new Request(destination, stay_open);
o.start();

If you directly call it like Request.prototype.start(), this will refer to the global context (window in browsers).

Also, if this is undefined, it results in an error. The if expression does not evaluate to false.

Update: this object is not set based on declaration, but by invocation. What it means is that if you assign the function property to a variable like x = o.start and call x(), this inside start no longer refers to o. This is what happens when you do setTimeout. To make it work, do this instead:

 var o = new Request(...);
 setTimeout(function() { o.start(); }, 1000);

You could also use a LEFT JOIN and IS NULL condition:

SELECT 
  mac, 
  creation_date 
FROM 
  logs
    LEFT JOIN consols ON logs.mac = consols.mac
WHERE 
  logs_type_id=11
AND
  consols.mac IS NULL;

An index on the "mac" columns might improve performance.

You can also do this easily in Pandas, if your data is represented in a Dataframe, as described here:

http://pandas.pydata.org/pandas-docs/version/0.15.0/visualization.html#scatter-plot

yes, it was introduced in 1993.

In Java you can only import class Names, or static methods/fields.

To import class use

import full.package.name.of.SomeClass;

to import static methods/fields use

import static full.package.name.of.SomeClass.staticMethod;
import static full.package.name.of.SomeClass.staticField;

Assuming one has installed a JDK in /opt/java/jdk1.8.0_144 then:

1. Install the alternative for javac

   $ sudo update-alternatives --install /usr/bin/javac javac /opt/java/jdk1.8.0_144/bin/javac 1
   

2. Check / update the alternatives config:

   $ sudo update-alternatives --config javac
   

If there is only a single alternative for javac you will get a message saying so, otherwise select the option for the new JDK.

To check everything is setup correctly then:

$ which javac
/usr/bin/javac

$ ls -l /usr/bin/javac
lrwxrwxrwx 1 root root 23 Sep  4 17:10 /usr/bin/javac -> /etc/alternatives/javac

$ ls -l /etc/alternatives/javac
lrwxrwxrwx 1 root root 32 Sep  4 17:10 /etc/alternatives/javac -> /opt/java/jdk1.8.0_144/bin/javac

And finally

$ javac -version
javac 1.8.0_144

Repeat for java, keytool, jar, etc as needed.

just to make the Answer 2 much easier, you can also define the folder where you can put your saved file

    spool /home/admin/myoutputfile.txt
    select * from table_name;
    spool off;

after that only with nano or vi myoutputfile.txt, you will see all the sql track.

hope is that help :)

As of Retrofit 2.0.0-beta2, if you have a service responding JSON from this URL : http://myhost/mypath

The following is not working :

public interface ClientService {
    @GET("")
    Call<List<Client>> getClientList();
}

Retrofit retrofit = new Retrofit.Builder()
    .baseUrl("http://myhost/mypath")
    .addConverterFactory(GsonConverterFactory.create())
    .build();

ClientService service = retrofit.create(ClientService.class);

Response<List<Client>> response = service.getClientList().execute();

But this is ok :

public interface ClientService {
    @GET
    Call<List<Client>> getClientList(@Url String anEmptyString);
}

Retrofit retrofit = new Retrofit.Builder()
    .baseUrl("http://myhost/mypath")
    .addConverterFactory(GsonConverterFactory.create())
    .build();

ClientService service = retrofit.create(ClientService.class);

Response<List<Client>> response = service.getClientList("").execute();

What worked for me (with JDK7) was the following:

1. Download the openjdk-xy-sources.jar from GrepCode,
2. rename the file to src.zip,
3. copy src.zip to the root folder of the JRE/JDK added to eclipse (the one with bin and lib folders in it)
4. restart eclipse

Alternatively, if you don't want to write to your JDK folder, you could also attach src.zip to (at least) rt.jar in eclipse in the Window | Preferences menu in Java | Installed JREs.

If you're not comfortable with downloading the sources from GrepCode, you could also get them from openJDK directly. This requires requires a bit more effort, though. Replace step one above by the following steps:

1. Download the JDK sources from here,
2. extract all folders from the zip file's *openjdk\jdk\src\share\classes* folder,
3. create a file src.zip and add these folders to it,
4. copy src.zip to the root folder of the JRE/JDK added to eclipse (the one with bin and lib folders in it)
5. restart eclipse

A third alternative to acquire src.zip is to download the unofficial OpenJDK builds from here. The src.zip is contained within the downloaded zip.

Well, first of all, in Python there is no ! operator, that'd be not. But open would not fail silently either - it would throw an exception. And the blocks need to be indented properly - Python uses whitespace to indicate block containment.

Thus we get:

fn = input('Enter file name: ')
try:
    file = open(fn, 'r')
except IOError:
    file = open(fn, 'w')

The code from Jaldhi Bhatt doesn't works for me.

Flutter throws a 'Navigator operation requested with a context that does not include a Navigator.'

I fixed the code wrapping the Navigator consumer component inside of another component that initialize the Navigator context using routes, as mentioned in this article.

import 'dart:async';

import 'package:flutter/material.dart';
import 'package:my-app/view/main-view.dart';

class SplashView extends StatelessWidget {

  @override
  Widget build(BuildContext context) {
    return new MaterialApp(
        home: Builder(
          builder: (context) => new _SplashContent(),
        ),
        routes: <String, WidgetBuilder>{
          '/main': (BuildContext context) => new MainView()}
    );
  }
}

class _SplashContent extends StatefulWidget{

  @override
  _SplashContentState createState() => new _SplashContentState();
}

class _SplashContentState extends State<_SplashContent>
    with SingleTickerProviderStateMixin {

  var _iconAnimationController;
  var _iconAnimation;

  startTimeout() async {
    var duration = const Duration(seconds: 3);
    return new Timer(duration, handleTimeout);
  }

  void handleTimeout() {
    Navigator.pushReplacementNamed(context, "/main");
  }

  @override
  void initState() {
    super.initState();

    _iconAnimationController = new AnimationController(
        vsync: this, duration: new Duration(milliseconds: 2000));

    _iconAnimation = new CurvedAnimation(
        parent: _iconAnimationController, curve: Curves.easeIn);
    _iconAnimation.addListener(() => this.setState(() {}));

    _iconAnimationController.forward();

    startTimeout();
  }

  @override
  Widget build(BuildContext context) {
    return new Center(
        child: new Image(
          image: new AssetImage("images/logo.png"),
          width: _iconAnimation.value * 100,
          height: _iconAnimation.value * 100,
        )
    );
  }
}

fill_parent :

A component is arranged layout for the fill_parent will be mandatory to expand to fill the layout unit members, as much as possible in the space. This is consistent with the dockstyle property of the Windows control. A top set layout or control to fill_parent will force it to take up the entire screen.

wrap_content

Set up a view of the size of wrap_content will be forced to view is expanded to show all the content. The TextView and ImageView controls, for example, is set to wrap_content will display its entire internal text and image. Layout elements will change the size according to the content. Set up a view of the size of Autosize attribute wrap_content roughly equivalent to set a Windows control for True.

Add GROUP BY to field you want to check for duplicates your query may look like

SELECT field1, field2, field3, ......   FROM table GROUP BY field1

field1 will be checked to exclude duplicate records

or you may query like

SELECT *  FROM table GROUP BY field1

duplicate records of field1 are excluded from SELECT

If you want to store multiple values for a key (if I understand you correctly), you could try a MultiHashMap (available in various libraries, not only commons-collections).

This explanation might help: http://code.google.com/p/android/issues/detail?id=8488#c80

"Fast Tips:

1) NEVER call System.gc() yourself. This has been propagated as a fix here, and it doesn't work. Do not do it. If you noticed in my explanation, before getting an OutOfMemoryError, the JVM already runs a garbage collection so there is no reason to do one again (its slowing your program down). Doing one at the end of your activity is just covering up the problem. It may causes the bitmap to be put on the finalizer queue faster, but there is no reason you couldn't have simply called recycle on each bitmap instead.

2) Always call recycle() on bitmaps you don't need anymore. At the very least, in the onDestroy of your activity go through and recycle all the bitmaps you were using. Also, if you want the bitmap instances to be collected from the dalvik heap faster, it doesn't hurt to clear any references to the bitmap.

3) Calling recycle() and then System.gc() still might not remove the bitmap from the Dalvik heap. DO NOT BE CONCERNED about this. recycle() did its job and freed the native memory, it will just take some time to go through the steps I outlined earlier to actually remove the bitmap from the Dalvik heap. This is NOT a big deal because the large chunk of native memory is already free!

4) Always assume there is a bug in the framework last. Dalvik is doing exactly what its supposed to do. It may not be what you expect or what you want, but its how it works. "

I agree with peterh's answer, so for those of you who like to copy and paste instead of 60 more seconds of Googling:

private String getComputerName()
{
    Map<String, String> env = System.getenv();
    if (env.containsKey("COMPUTERNAME"))
        return env.get("COMPUTERNAME");
    else if (env.containsKey("HOSTNAME"))
        return env.get("HOSTNAME");
    else
        return "Unknown Computer";
}

I have tested this in Windows 7 and it works. If peterh was right the else if should take care of Mac and Linux. Maybe someone can test this? You could also implement Brian Roach's answer inside the else if you wanted extra robustness.

As other have mentioned you can't display an image in an alert. The solution is to show it on the webpage.

If I have my webpage paused in the debugger and I already have an image loaded, I can display it. There is no need to use jQuery; with this native 14 lines of Javascript it will work from code or the debugger command line:

function show(img){
 var _=document.getElementById('_'); 
 if(!_){_=document.createElement('canvas');document.body.appendChild(_);}
 _.id='_';
 _.style.top=0;
 _.style.left=0;
 _.width=img.width;
 _.height=img.height;
 _.style.zIndex=9999; 
 _.style.position='absolute';
 _.getContext('2d').drawImage(img,0,0);
}

Usage:

show( myimage );

This is what I got from oracle documentation, but it is for oracle 10g release 2:

When you define a NUMBER variable, you can specify its precision (p) and scale (s) so that it is sufficiently, but not unnecessarily, large. Precision is the number of significant digits. Scale can be positive or negative. Positive scale identifies the number of digits to the right of the decimal point; negative scale identifies the number of digits to the left of the decimal point that can be rounded up or down.

The NUMBER data type is supported by Oracle Database standard libraries and operates the same way as it does in SQL. It is used for dimensions and surrogates when a text or INTEGER data type is not appropriate. It is typically assigned to variables that are not used for calculations (like forecasts and aggregations), and it is used for variables that must match the rounding behavior of the database or require a high degree of precision. When deciding whether to assign the NUMBER data type to a variable, keep the following facts in mind in order to maximize performance:

• Analytic workspace calculations on NUMBER variables is slower than other numerical data types because NUMBER values are calculated in software (for accuracy) rather than in hardware (for speed).
• When data is fetched from an analytic workspace to a relational column that has the NUMBER data type, performance is best when the data already has the NUMBER data type in the analytic workspace because a conversion step is not required.

For Perfect DateTime Match in SQL Server

SELECT ID FROM [Table Name] WHERE (DateLog between '2017-02-16 **00:00:00.000**' and '2017-12-16 **23:59:00.999**') ORDER BY DateLog DESC

Will the conditions be ORed or ANDed together?

Starts with: abc
Ends with: xyz
Contains: 123
Doesn't contain: 456

The OR version is fairly simple; as you said, it's mostly a matter of inserting pipes between individual conditions. The regex simply stops looking for a match as soon as one of the alternatives matches.

/^abc|xyz$|123|^(?:(?!456).)*$/

That fourth alternative may look bizarre, but that's how you express "doesn't contain" in a regex. By the way, the order of the alternatives doesn't matter; this is effectively the same regex:

/xyz$|^(?:(?!456).)*$|123|^abc/

The AND version is more complicated. After each individual regex matches, the match position has to be reset to zero so the next regex has access to the whole input. That means all of the conditions have to be expressed as lookaheads (technically, one of them doesn't have to be a lookahead, I think it expresses the intent more clearly this way). A final .*$ consummates the match.

/^(?=^abc)(?=.*xyz$)(?=.*123)(?=^(?:(?!456).)*$).*$/

And then there's the possibility of combined AND and OR conditions--that's where the real fun starts. :D

According to the docs numpy.loadtxt is

a fast reader for simply formatted files. The genfromtxt function provides more sophisticated handling of, e.g., lines with missing values.

so there are only a few options to handle more complicated files. As mentioned numpy.genfromtxt has more options. So as an example you could use

import numpy as np
data = np.genfromtxt('e:\dir1\datafile.csv', delimiter=',', skip_header=10,
                     skip_footer=10, names=['x', 'y', 'z'])

to read the data and assign names to the columns (or read a header line from the file with names=True) and than plot it with

ax1.plot(data['x'], data['y'], color='r', label='the data')

I think numpy is quite well documented now. You can easily inspect the docstrings from within ipython or by using an IDE like spider if you prefer to read them rendered as HTML.

You may start with Titanium for desktop dev. Also you may have a look at Chromium Embedded Framework. It's basically a web browser control based on chromium.

It's written in C++ so you can do all the low level OS stuff you want(Growl, tray icons, local file access, com ports, etc) in your container app, and then all the application logic and gui in html/javascript. It allows you to intercept any http request to either serve local resources or perform some custom action. For example, a request to http://localapp.com/SetTrayIconState?state=active could be intercepted by the container and then call the C++ function to update the tray icon.

It also allows you to create functions that can be called directly from JavaScript.

It's very difficult to debug JavaScript directly in CEF. There's no support for anything like Firebug.

You may also try AppJS.com (Helps to build Desktop Applications. for Linux, Windows and Mac using HTML, CSS and JavaScript)

Also, as pointed out by @Clint, the team at brackets.io (Adobe) created an awesome shell using Chromium Embedded Framework that makes it much easier to get started. It is called the brackets shell: github.com/adobe/brackets-shell Find out more about it here: clintberry.com/2013/html5-desktop-apps-with-brackets-shell

Like Jaanus told:

Calling this (-selectRowAtIndexPath:animated:scrollPosition:) method does not cause the delegate to receive a tableView:willSelectRowAtIndexPath: or tableView:didSelectRowAtIndexPath: message, nor will it send UITableViewSelectionDidChangeNotification notifications to observers.

So you just have to call the delegate method yourself.

For example:

Swift 3 version:

let indexPath = IndexPath(row: 0, section: 0);
self.tableView.selectRow(at: indexPath, animated: false, scrollPosition: UITableViewScrollPosition.none)
self.tableView(self.tableView, didSelectRowAt: indexPath)

ObjectiveC version:

NSIndexPath *indexPath = [NSIndexPath indexPathForRow:0 inSection:0];
[self.tableView selectRowAtIndexPath:indexPath 
                            animated:YES 
                      scrollPosition:UITableViewScrollPositionNone];
[self tableView:self.tableView didSelectRowAtIndexPath:indexPath];

Swift 2.3 version:

 let indexPath = NSIndexPath(forRow: 0, inSection: 0);
 self.tableView.selectRowAtIndexPath(indexPath, animated: false, scrollPosition: UITableViewScrollPosition.None)
 self.tableView(self.tableView, didSelectRowAtIndexPath: indexPath)

Check if you mixed tabs and spaces, that is a frequent source of indentation errors.

Since Symfony 3.3 you can use binding, like

services:
_defaults:
    autowire: true      
    autoconfigure: true
    bind:
        $kernelProjectDir: '%kernel.project_dir%'

After that you can use parameter $kernelProjectDir in any controller OR service. Just like

class SomeControllerOrService
{
    public function someAction(...., $kernelProjectDir)
    {
          .....

I needed to test for an empty field in PHP and used

ctype_space($tempVariable)

which worked well for me.

import random
class a:
    foo = "bar"

a1 = a()
a2 = a()
b = [a1.foo,a2.foo]
random.shuffle(b)

The event attribute of <f:ajax> can hold at least all supported DOM events of the HTML element which is been generated by the JSF component in question. An easy way to find them all out is to check all on* attribues of the JSF input component of interest in the JSF tag library documentation and then remove the "on" prefix. For example, the <h:inputText> component which renders <input type="text"> lists the following on* attributes (of which I've already removed the "on" prefix so that it ultimately becomes the DOM event type name):

• blur
• change
• click
• dblclick
• focus
• keydown
• keypress
• keyup
• mousedown
• mousemove
• mouseout
• mouseover
• mouseup
• select

Additionally, JSF has two more special event names for EditableValueHolder and ActionSource components, the real HTML DOM event being rendered depends on the component type:

• valueChange (will render as change on text/select inputs and as click on radio/checkbox inputs)
• action (will render as click on command links/buttons)

The above two are the default events for the components in question.

Some JSF component libraries have additional customized event names which are generally more specialized kinds of valueChange or action events, such as PrimeFaces <p:ajax> which supports among others tabChange, itemSelect, itemUnselect, dateSelect, page, sort, filter, close, etc depending on the parent <p:xxx> component. You can find them all in the "Ajax Behavior Events" subsection of each component's chapter in PrimeFaces Users Guide.

editText.setRawInputType(InputType.TYPE_CLASS_NUMBER);

this works for me try it.

height:1rem;
font-size: 3.75em;

typeof(T).Name // class name, no namespace
typeof(T).FullName // namespace and class name
typeof(T).Namespace // namespace, no class name

At my work we have recently put together a couple of test suites written in Java to test some RESTful APIs we built. Our Services could invoke other RESTful APIs they depend on. We split it into two suites.

• Suite 1 - Testing each service in isolation
  • Mock any peer services the API depends on using restito. Other alternatives include rest-driver, wiremock and betamax.
  • Tests the service we are testing and the mocks all run in a single JVM
  • Launches the service in Jetty

I would definitely recommend doing this. It has worked really well for us. The main advantages are:

• Peer services are mocked, so you needn't perform any complicated data setup. Before each test you simply use restito to define how you want peer services to behave, just like you would with classes in unit tests with Mockito.
• You can ask the mocked peer services if they were called. You can't do these asserts as easily with real peer services.
• The suite is super fast as mocked services serve pre-canned in-memory responses. So we can get good coverage without the suite taking an age to run.
• The suite is reliable and repeatable as its isolated in it's own JVM, so no need to worry about other suites/people mucking about with an shared environment at the same time the suite is running and causing tests to fail.

• Suite 2 - Full End to End
  • Suite runs against a full environment deployed across several machines
  • API deployed on Tomcat in environment
  • Peer services are real 'as live' full deployments

This suite requires us to do data set up in peer services which means tests generally take more time to write. As much as possible we use REST clients to do data set up in peer services.

Tests in this suite usually take longer to write, so we put most of our coverage in Suite 1. That being said there is still clear value in this suite as our mocks in Suite 1 may not be behaving quite like the real services.

Inline elements (like SPAN, LABEL, etc.) are displayed so that their height and width are calculated by the browser based on their content. If you want to control height and width you have to change those elements' blocks.

display: block; makes the element displayed as a solid block (like DIV tags) which means that there is a line break after the element (it's not inline). Although you can use display: inline-block to fix the issue of line break, this solution does not work in IE6 because IE6 doesn't recognize inline-block. If you want it to be cross-browser compatible then look at this article: http://webjazz.blogspot.com/2008/01/getting-inline-block-working-across.html

You simply have to do:

INSERT INTO def (catid, title, page, publish) 
SELECT catid, title, 'page','yes' from `abc`

Locate the installation path of GlassFish. Then move to domains/domain-dir/logs/ and you'll find there the log files. If you have created the domain with NetBeans, the domain-dir is most probably called domain1.

See this link for the official GlassFish documentation about logging.

For multicolumn listbox extract data from any column of selected row by

 listboxControl.List(listboxControl.ListIndex,col_num)

where col_num is required column ( 0 for first column)

Use the following command

remove(list=c("data_1", "data_2", "data_3"))

If you have url with path variables, example www.myexampl.com/item/12/update where 12 is the id and create is the variable you want to use for specifying your execution for instance in using a single form to do an update and create, you do this in your controller.

   @PostMapping(value = "/item/{id}/{method}")
    public String getForm(@PathVariable("id") String itemId ,  
        @PathVariable("method") String methodCall , Model model){

     if(methodCall.equals("create")){
            //logic
      }
     if(methodCall.equals("update")){
            //logic
      }

      return "path to your form";
    }

You need to include stdint.h

 #include <stdint.h>

This problem might occur if you are behind corporate proxy and corporation uses its own certificate. Just add "--no-check-certificate" in the command. e.g. wget --no-check-certificate -qO - http://pkg.jenkins-ci.org/debian/jenkins-ci.org.key | sudo apt-key add -

It works. If you want to see what is going on, you can use verbose command instead of quiet before adding "--no-check-certificate" option. e.g. wget -vO - http://pkg.jenkins-ci.org/debian/jenkins-ci.org.key | sudo apt-key add - This will tell you to use "--no-check-certificate" if you are behind proxy.

To support the answer by @oberstet, if the cert is not trusted by the browser (for example you get a "this site is not secure, do you want to continue?") one solution is to open the browser options, navigate to the certificates settings and add the host and post that the websocket server is being served from to the certificate provider as an exception.

for example add 'example-wss-domain.org:6001' as an exception to 'Certificate Provider Ltd'.

In firefox, this can be done from 'about:preferences' and searching for 'Certificates'

Interestingly I checked this on an app of mine and I got the same error.

I spent a while checking through headers to see if there was anything undef'ing the _USE_MATH_DEFINES and found nothing.

So I moved the

#define _USE_MATH_DEFINES
#include <cmath>

to be the first thing in my file (I don't use PCHs so if you are you will have to have it after the #include "stdafx.h") and suddenly it compile perfectly.

Try moving it higher up the page. Totally unsure as to why this would cause issues though.

Edit: Figured it out. The #include <math.h> occurs within cmath's header guards. This means that something higher up the list of #includes is including cmath without the #define specified. math.h is specifically designed so that you can include it again with that define now changed to add M_PI etc. This is NOT the case with cmath. So you need to make sure you #define _USE_MATH_DEFINES before you include anything else. Hope that clears it up for you :)

Failing that just include math.h you are using non-standard C/C++ as already pointed out :)

Edit 2: Or as David points out in the comments just make yourself a constant that defines the value and you have something more portable anyway :)

You will see this error in case a some class in your library file you have in classpath has reference to non-existing classe(s) which could be in another jar file. Here, I received this error when I did not add org.springframework.beans-3.1.2.RELEASE.jar and had extended a class from org.springframework.jdbc.core.support.JdbcDaoSupport, which was in org.springframework.jdbc-3.1.2.RELEASE.jar of my classpath.

var apps = [{id:34,name:'My App',another:'thing'},{id:37,name:'My New App',another:'things'}];

// get index of object with id:37

var removeIndex = apps.map(function(item) { return item.id; }).indexOf(37);

// remove object

apps.splice(removeIndex, 1);

This one worked for me:

In Activity:

User user;
public User getUser(){ return this.user;}

In Fragment's onCreateView method:

User user = ((MainActivity)getActivity()).getUser(); 

Replace the MainActivity with your Activity Name.

For long arrays

s = np.empty(len(var))

s[:] = np.nan

for  x in  set(var):

    x_positions = np.where(var==x)

    s[x_positions[0][0]]=x


sorted_var=s[~np.isnan(s)]

Not an answer to your question (which others have answered), but if you want to have some edit functionality of an uploaded file field, what you probably want to do is:

• show the current value of this field by just printing the filename or URL, a clickable link to download it, or if it's an image: just show it, possibly as thumbnail
• the <input> tag to upload a new file
• a checkbox that, when checked, deletes the currently uploaded file. note that there's no way to upload an 'empty' file, so you need something like this to clear out the field's value

Using String#gsub with regular expression:

"((String1))".gsub(/^\(+|\)+$/, '')
# => "String1"
"(((((( parentheses )))".gsub(/^\(+|\)+$/, '')
# => " parentheses "

This will remove surrounding parentheses only.

"(((((( This (is) string )))".gsub(/^\(+|\)+$/, '')
# => " This (is) string "

In PostgreSQL 9.6, there's a new option idle_in_transaction_session_timeout which should accomplish what you describe. You can set it using the SET command, e.g.:

SET SESSION idle_in_transaction_session_timeout = '5min';

You need to remove the static from your accessor methods - these methods need to be instance methods and access the instance variables

public class IDCard {
    public String name, fileName;
    public int id;

    public IDCard(final String name, final String fileName, final int id) {
        this.name = name;
        this.fileName = fileName
        this.id = id;
    }

    public String getName() {
        return name;
    }
}

You can the create an IDCard and use the accessor like this:

final IDCard card = new IDCard();
card.getName();

Each time you call new a new instance of the IDCard will be created and it will have it's own copies of the 3 variables.

If you use the static keyword then those variables are common across every instance of IDCard.

A couple of things to bear in mind:

1. don't add useless comments - they add code clutter and nothing else.
2. conform to naming conventions, use lower case of variable names - name not Name.

You can do it with CSS:

<iframe style="position: absolute; height: 100%; border: none"></iframe>

Be aware that this will by default place it in the upper-left corner of the page, but I guess that is what you want to achieve. You can position with the left,right, top and bottom CSS properties.

Using data.frame instead of cbind should be helpful

x <- data.frame(col1=c(10, 20), col2=c("[]", "[]"), col3=c("[[1,2]]","[[1,3]]"))
x
  col1 col2    col3
1   10   [] [[1,2]]
2   20   [] [[1,3]]

sapply(x, class) # looking into x to see the class of each element
     col1      col2      col3 
"numeric"  "factor"  "factor" 

As you can see elements from col1 are numeric as you wish.

data.frame can have variables of different class: numeric, factor and character but matrix doesn't, once you put a character element into a matrix all the other will become into this class no matter what clase they were before.

Here is another concrete example.It is for a shared library. The shared library's main function is to communicate with a smart card reader. But it can also receive 'configuration information' at runtime over udp. The udp is handled by a thread which MUST be started at init time.

__attribute__((constructor))  static void startUdpReceiveThread (void) {
    pthread_create( &tid_udpthread, NULL, __feigh_udp_receive_loop, NULL );
    return;

  }

The library was written in c.

I solved the problem with these online tools:

1. To check if the Json structure is OKAY: http://jsonlint.com/
2. To generate my Object class from my Json structure: https://www.jsonutils.com/

The simple code:

RootObject rootObj= JsonConvert.DeserializeObject<RootObject>(File.ReadAllText(pathFile));

As long as your program's in a sane state, you can also call (void)puts(your_string) to print it to stdout. Same principle applies to all functions available to the debugger, actually.

Much better to use following:

For is not null:

where('archived IS NOT NULL', null);

For is null:

where('archived', null);

Tomcat will only extract the war which is copied to webapps directory. Change Dockerfile as below:

FROM tomcat:8.0.20-jre8
COPY /1.0-SNAPSHOT/my-app-1.0-SNAPSHOT.war /usr/local/tomcat/webapps/myapp.war

You might need to access the url as below unless you have specified the webroot

http://192.168.59.103:8888/myapp/getData

Using <summary> and <details>

Using <summary> and <details> elements is the simplest but see browser support as current IE is not supporting it. You can polyfill though (most are jQuery-based). Do note that unsupported browser will simply show the expanded version of course, so that may be acceptable in some cases.

/* Optional styling */_x000D_
summary::-webkit-details-marker {_x000D_
  color: blue;_x000D_
}_x000D_
summary:focus {_x000D_
  outline-style: none;_x000D_
}

<details>_x000D_
  <summary>Summary, caption, or legend for the content</summary>_x000D_
  Content goes here._x000D_
</details>

See also how to style the <details> element (HTML5 Doctor) (little bit tricky).

Pure CSS3

The :target selector has a pretty good browser support, and it can be used to make a single collapsible element within the frame.

.details,_x000D_
.show,_x000D_
.hide:target {_x000D_
  display: none;_x000D_
}_x000D_
.hide:target + .show,_x000D_
.hide:target ~ .details {_x000D_
  display: block;_x000D_
}

<div>_x000D_
  <a id="hide1" href="#hide1" class="hide">+ Summary goes here</a>_x000D_
  <a id="show1" href="#show1" class="show">- Summary goes here</a>_x000D_
  <div class="details">_x000D_
    Content goes here._x000D_
  </div>_x000D_
</div>_x000D_
<div>_x000D_
  <a id="hide2" href="#hide2" class="hide">+ Summary goes here</a>_x000D_
  <a id="show2" href="#show2" class="show">- Summary goes here</a>_x000D_
  <div class="details">_x000D_
    Content goes here._x000D_
  </div>_x000D_
</div>

2>&1 is a POSIX shell construct. Here is a breakdown, token by token:

2: "Standard error" output file descriptor.

>&: Duplicate an Output File Descriptor operator (a variant of Output Redirection operator >). Given [x]>&[y], the file descriptor denoted by x is made to be a copy of the output file descriptor y.

1 "Standard output" output file descriptor.

The expression 2>&1 copies file descriptor 1 to location 2, so any output written to 2 ("standard error") in the execution environment goes to the same file originally described by 1 ("standard output").

Further explanation:

File Descriptor: "A per-process unique, non-negative integer used to identify an open file for the purpose of file access."

Standard output/error: Refer to the following note in the Redirection section of the shell documentation:

Open files are represented by decimal numbers starting with zero. The largest possible value is implementation-defined; however, all implementations shall support at least 0 to 9, inclusive, for use by the application. These numbers are called "file descriptors". The values 0, 1, and 2 have special meaning and conventional uses and are implied by certain redirection operations; they are referred to as standard input, standard output, and standard error, respectively. Programs usually take their input from standard input, and write output on standard output. Error messages are usually written on standard error. The redirection operators can be preceded by one or more digits (with no intervening characters allowed) to designate the file descriptor number.

Unfortunately, Dictionary has problems with Model Binding in MVC. Read the full story here. Instead, create a custom model binder to get the Dictionary as a parameter for the controller action.

To solve your requirement, here is the working solution -

First create your ViewModels in following way. PersonModel can have list of RoleModels.

public class PersonModel
{
    public List<RoleModel> Roles { get; set; }
    public string Name { get; set; }
}

public class RoleModel
{
    public string RoleName { get; set;}
    public string Description { get; set;}
}

Then have a index action which will be serving basic index view -

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

Index view will be having following JQuery AJAX POST operation -

<script src="~/Scripts/jquery-1.10.2.min.js"></script>
<script>
    $(function () {
        $('#click1').click(function (e) {

            var jsonObject = {
                "Name" : "Rami",
                "Roles": [{ "RoleName": "Admin", "Description" : "Admin Role"}, { "RoleName": "User", "Description" : "User Role"}]
            };

            $.ajax({
                url: "@Url.Action("AddUser")",
                type: "POST",
                data: JSON.stringify(jsonObject),
                contentType: "application/json; charset=utf-8",
                dataType: "json",
                error: function (response) {
                    alert(response.responseText);
            },
                success: function (response) {
                    alert(response);
                }
            });

        });
    });
</script>

<input type="button" value="click1" id="click1" />

Index action posts to AddUser action -

[HttpPost]
public ActionResult AddUser(PersonModel model)
{
    if (model != null)
    {
        return Json("Success");
    }
    else
    {
        return Json("An Error Has occoured");
    }
}

So now when the post happens you can get all the posted data in the model parameter of action.

Update:

For asp.net core, to get JSON data as your action parameter you should add the [FromBody] attribute before your param name in your controller action. Note: if you're using ASP.NET Core 2.1, you can also use the [ApiController] attribute to automatically infer the [FromBody] binding source for your complex action method parameters. (Doc)

You can use the Enumerable.SequenceEqual() in the System.Linq to compare the contents in the array

bool isEqual = Enumerable.SequenceEqual(target1, target2);

First Question: Difference between parseInt and valueOf in java?

Second Question:

NumberFormat format = NumberFormat.getInstance(Locale.FRANCE);
Number number = format.parse("1,234");
double d = number.doubleValue();

Third Question:

DecimalFormat df = new DecimalFormat();
DecimalFormatSymbols symbols = new DecimalFormatSymbols();
symbols.setDecimalSeparator('.');
symbols.setGroupingSeparator(',');
df.setDecimalFormatSymbols(symbols);
df.parse(p);

I know it's quite late but in case someone needs a simple solution, the cool thing is you can also add the where clause with it:

public static void DeleteWhere<T>(this DbContext db, Expression<Func<T, bool>> filter) where T : class
{
    string selectSql = db.Set<T>().Where(filter).ToString();
    string fromWhere = selectSql.Substring(selectSql.IndexOf("FROM"));
    string deleteSql = "DELETE [Extent1] " + fromWhere;
    db.Database.ExecuteSqlCommand(deleteSql);
}

Note: just tested with MSSQL2008.

Update:

The solution above won't work when EF generates sql statement with parameters, so here's the update for EF5:

public static void DeleteWhere<T>(this DbContext db, Expression<Func<T, bool>> filter) where T : class
{
    var query = db.Set<T>().Where(filter);

    string selectSql = query.ToString();
    string deleteSql = "DELETE [Extent1] " + selectSql.Substring(selectSql.IndexOf("FROM"));

    var internalQuery = query.GetType().GetFields(BindingFlags.NonPublic | BindingFlags.Instance).Where(field => field.Name == "_internalQuery").Select(field => field.GetValue(query)).First();
    var objectQuery = internalQuery.GetType().GetFields(BindingFlags.NonPublic | BindingFlags.Instance).Where(field => field.Name == "_objectQuery").Select(field => field.GetValue(internalQuery)).First() as ObjectQuery;
    var parameters = objectQuery.Parameters.Select(p => new SqlParameter(p.Name, p.Value)).ToArray();

    db.Database.ExecuteSqlCommand(deleteSql, parameters);
}

It requires a little bit of reflection but works well.

.fa-circle{_x000D_
  color: tomato;_x000D_
}_x000D_
_x000D_
div{_x000D_
  font-size: 100px;_x000D_
}

<link href="https://maxcdn.bootstrapcdn.com/font-awesome/4.7.0/css/font-awesome.min.css" rel="stylesheet"/>_x000D_
<div><i class="fa fa-circle" aria-hidden="true"></i></div>

Just wanted to mention another solution which answers the question of "Easier way to create circle div than using an image?" which is to use FontAwesome.

You import the fontawesome css file or from the CDN here

and then you just:

<div><i class="fa fa-circle" aria-hidden="true"></i></div>

and you can give it any color you want any font size.

Use git reflog to find the hashes of previously checked out commits.

A shortcut command to get to your last checked out branch (not sure if this work correctly with detached HEAD and intermediate commits though) is git checkout -

This is a fairly old thread, but since I was reinstalling my Visual Studio 2015 Community today, I thought I might add some info on what to use on VS2015, or what might work in general.

To see which instances were installed by default, type sqllocaldb info inside a command prompt. On my machine, I get two instances, the first one named MSSQLLocalDB.

C:\>sqllocaldb info
MSSQLLocalDB
ProjectsV13

You can also create a new instance if you wish, using sqllocaldb create "some_instance_name", but the default one will work just fine:

// if not using a verbatim string literal, don't forget to escape backslashes
@"Server=(localdb)\MSSQLLocalDB;Integrated Security=true;"

URLs can give a lot of clues, especially with Content Management Systems.

For example "http://abcxyz.com/node/46" looks a lot like Drupal.

Also many frameworks have standard JavaScript and CSS files they use.

If you are using "MTP mode" for USB computer connection. Change it to "PTP mode" or "Card reader mode".

I have same issue and it works fine to me.

If you are trying to build John the Ripper "bleeding-jumbo" and get an error like "make: *** No rule to make target 'linux-x86-64'". Try running this command instead: ./configure && make

In application.properties file present in resources:

server.port=8082

Suppose your function enters data in columns A and B and you want to a custom Userform to appear if the user selects a cell in column C. One way to do this is to use the SelectionChange event:

Private Sub Worksheet_SelectionChange(ByVal Target As Range)
    Dim clickRng As Range
    Dim lastRow As Long

    lastRow = Range("A1").End(xlDown).Row
    Set clickRng = Range("C1:C" & lastRow) //Dynamically set cells that can be clicked based on data in column A

    If Not Intersect(Target, clickRng) Is Nothing Then
        MyUserForm.Show //Launch custom userform
    End If

End Sub

Note that the userform will appear when a user selects any cell in Column C and you might want to populate each cell in Column C with something like "select cell to launch form" to make it obvious that the user needs to perform an action (having a button naturally suggests that it should be clicked)

From this tutorial:

<style name="CustomProgressBarHorizontal" parent="android:Widget.ProgressBar.Horizontal">
      <item name="android:progressDrawable">@drawable/custom_progress_bar_horizontal</item>
      <item name="android:minHeight">10dip</item>
      <item name="android:maxHeight">20dip</item>
</style>

Then simply apply the style to your progress bars or better, override the default style in your theme to style all of your app's progress bars automatically.

The difference you are seeing in the screenshots is because the phones/emulators are using a difference Android version (latest is the theme from ICS (Holo), top is the original theme).

Inline code takes higher precedence than the other ones. To call your other function func () call it from the f1 ().

Inside your function, add a line,

function fun () {
// Your code here
}

function f1()
    {
       alert("f1 called");
       //form validation that recalls the page showing with supplied inputs.    

fun ();

    }

Rewriting your whole code,

 <!DOCTYPE html>
    <html>
      <head>

      <script>

       function fun()
        {
         alert("hello");
         //validation code to see State field is mandatory.  
        }   

        function f1()
        {
           alert("f1 called");
           //form validation that recalls the page showing with supplied inputs.   
           fun (); 
        }

      </script>
      </head>
      <body>
       <form name="form1" id="form1" method="post">

         State: <select id="state ID">
                   <option></option>
                   <option value="ap">ap</option>
                   <option value="bp">bp</option>
                </select>
       </form>
       <table><tr><td id="Save" onclick="f1()">click</td></tr></table>

      </body>
</html>

To obtain the column count on a table, use this:

select count(id) from syscolumns where id = object_id('tablename')

and to pass a table to a function, try XML as show here:

create function dbo.ReadXml (@xmlMatrix xml)
returns table
as
return
( select
t.value('./@Salary', 'integer') as Salary,
t.value('./@Age', 'integer') as Age
from @xmlMatrix.nodes('//row') x(t)
)
go

declare @source table
( Salary integer,
age tinyint
)
insert into @source
select 10000, 25 union all
select 15000, 27 union all
select 12000, 18 union all
select 15000, 36 union all
select 16000, 57 union all
select 17000, 44 union all
select 18000, 32 union all
select 19000, 56 union all
select 25000, 34 union all
select 7500, 29
--select * from @source

declare @functionArgument xml

select @functionArgument =
( select
Salary as [row/@Salary],
Age as [row/@Age]
from @source
for xml path('')
)
--select @functionArgument as [@functionArgument]

select * from readXml(@functionArgument)

/* -------- Sample Output: --------
Salary Age
----------- -----------
10000 25
15000 27
12000 18
15000 36
16000 57
17000 44
18000 32
19000 56
25000 34
7500 29

Escaped percent sign is double percent (%%):

System.out.printf("2 out of 10 is %d%%", 20);

You can use URL encoding to encode the newline as %0A.

mailto:[email protected]?subject=test&body=type%20your%0Amessage%20here

While the above appears to work in many cases, user olibre points out that the RFC governing the mailto URI scheme specifies that %0D%0A (carriage return + line feed) should be used instead of %0A (line feed). See also: Newline Representations.

Read /usr/src/linux/Documentation/sysctl/kernel.txt.

[/proc/sys/kernel/]core_pattern is used to specify a core dumpfile pattern name.

• If the first character of the pattern is a '|', the kernel will treat the rest of the pattern as a command to run. The core dump will be written to the standard input of that program instead of to a file.

Instead of writing the core dump to disk, your system is configured to send it to the abrt program instead. Automated Bug Reporting Tool is possibly not as documented as it should be...

In any case, the quick answer is that you should be able to find your core file in /var/cache/abrt, where abrt stores it after being invoked. Similarly, other systems using Apport may squirrel away cores in /var/crash, and so on.

I'm guessing that you don't need to re-increment the existing data so, why can't you just run a simple ALTER TABLE command to change the PK's attributes?

Something like:

ALTER TABLE `content` CHANGE `id` `id` SMALLINT( 5 ) UNSIGNED NOT NULL AUTO_INCREMENT 

I've tested this code on my own MySQL database and it works but I have not tried it with any meaningful number of records. Once you've altered the row then you need to reset the increment to a number guaranteed not to interfere with any other records.

ALTER TABLE `content` auto_increment = MAX(`id`) + 1

Again, untested but I believe it will work.

To check the version of R execute : R --version

Or after you are in the R shell print the contents of version$version.string

EDIT

To check the version of installed packages do the following.

After loading the library, you can execute sessionInfo ()

But to know the list of all installed packages:

packinfo <- installed.packages(fields = c("Package", "Version"))
packinfo[,c("Package", "Version")]

OR to extract a specific library version, once you have extracted the information using the installed.package function as above just use the name of the package in the first dimension of the matrix.

packinfo["RANN",c("Package", "Version")]
packinfo["graphics",c("Package", "Version")]

The above will print the versions of the RANN library and the graphics library.

Both pandas and matplotlib.dates use matplotlib.units for locating the ticks.

But while matplotlib.dates has convenient ways to set the ticks manually, pandas seems to have the focus on auto formatting so far (you can have a look at the code for date conversion and formatting in pandas).

So for the moment it seems more reasonable to use matplotlib.dates (as mentioned by @BrenBarn in his comment).

import numpy as np
import pandas as pd
import matplotlib.pyplot as plt 
import matplotlib.dates as dates

idx = pd.date_range('2011-05-01', '2011-07-01')
s = pd.Series(np.random.randn(len(idx)), index=idx)

fig, ax = plt.subplots()
ax.plot_date(idx.to_pydatetime(), s, 'v-')
ax.xaxis.set_minor_locator(dates.WeekdayLocator(byweekday=(1),
                                                interval=1))
ax.xaxis.set_minor_formatter(dates.DateFormatter('%d\n%a'))
ax.xaxis.grid(True, which="minor")
ax.yaxis.grid()
ax.xaxis.set_major_locator(dates.MonthLocator())
ax.xaxis.set_major_formatter(dates.DateFormatter('\n\n\n%b\n%Y'))
plt.tight_layout()
plt.show()

(my locale is German, so that Tuesday [Tue] becomes Dienstag [Di])

Only static functions are called with class name.

classname::Staicfunction();

Non static functions have to be called using objects.

classname obj;
obj.Somefunction();

This is exactly what your error means. Since your function is non static you have to use a object reference to invoke it.

You could also use bc

hour=8
result=$(echo "$hour + 1" | bc)
echo $result
9

You should be able to use the IF function for that. the syntax is =IF(condition, value_if_true, value_if_false). To add an extra column with only the non-reimbursed amounts, you would use something like:

=IF(B1="No", A1, 0)

and sum that. There's probably a way to include it in a single cell below the column as well, but off the top of my head I can't think of anything simple.

There could be any of the following, but all of them lead into DOM not loaded before its accessed by the javascript.

So here is what you have to ensure before actually calling JS code: * Make sure the container has loaded before any javascript is called * Make sure the target URL is loaded in whatever container it has to

I came across the similar issue but on my local when I am trying to have my Javascript run well before onLoad of the main page which causes the error message. I have fixed it by simply waiting for whole page to load and then call the required function.

You could simply do this by adding a timeout function when page has loaded and call your onload event like:

window.onload = new function() { setTimeout(function() { // some onload event }, 10); }

that will ensure what you are trying will execute well after onLoad is trigger.

This worked for my tests;

This is CLEANEST, SIMPLEST ANSWER for CONTIGUOUS NON-PRINTING Ruby Code:

The below also happens to answer the Original Poster's question without, the "ugly" conditional code that some commenters have mentioned.

1. CONTIGUOUS NON-PRINTING Ruby Code

   • This will work in any mixed language Rails View file, e.g, *.html.erb, *.js.erb, *.rhtml, etc.

   • This should also work with STD OUT/printing code, e.g. <%#= f.label :title %>

   • DETAILS:

     Rather than use rails brackets on each line and commenting in front of each starting bracket as we usually do like this:

       <%# if flash[:myErrors] %>

     YOU CAN INSTEAD add only one comment (hashmark/poundsign) to the first open Rails bracket if you write your code as one large block... LIKE THIS:

       <%# 
         if flash[:myErrors] then
           if flash[:myErrors].any? then
             if @post.id.nil? then
               if @myPost!=-1 then
                 @post = @myPost 
               else 
                 @post = Post.new 
               end 
             end 
           end 
         end 
       %>
     

You can access the USB drive by its drive letter. To know the drive letter you can run this command:

C:\>wmic logicaldisk where drivetype=2 get deviceid, volumename, description

From here you will get the drive letter (Device ID) of your USB drive.

For example if its F: then run the following command in command prompt to see its contents:

C:\> F:

F:\> dir

Here's mine:

String.format = function(tokenised){
        var args = arguments;
        return tokenised.replace(/{[0-9]}/g, function(matched){
            matched = matched.replace(/[{}]/g, "");
            return args[parseInt(matched)+1];             
        });
    }

Not bullet proof but works if you use it sensibly.

So do you want them to get the IE password-challenge box, or should they be directed to your login page and enter their information there? If it's the second option, then you should at least enable Anonymous access to your login page, since the site won't know who they are yet.

If you want the first option, then the login page they're getting forwarded to will need to read the currently logged-in user and act based on that, since they would have had to correctly authenticate to get this far.

The whole "reverse a string in place" is an antiquated interview question C programmers, and people who were interviewed by them (for revenge, maybe?), will ask. Unfortunately, it's the "In Place" part that no longer works because strings in pretty much any managed language (JS, C#, etc) uses immutable strings, thus defeating the whole idea of moving a string without allocating any new memory.

While the solutions above do indeed reverse a string, they do not do it without allocating more memory, and thus do not satisfy the conditions. You need to have direct access to the string as allocated, and be able to manipulate its original memory location to be able to reverse it in place.

Personally, i really hate these kinds of interview questions, but sadly, i'm sure we'll keep seeing them for years to come.

You can run a JAR file from the command line like this:

Better Way to Provide Choice inside a django Model :

from django.db import models

class Student(models.Model):
    FRESHMAN = 'FR'
    SOPHOMORE = 'SO'
    JUNIOR = 'JR'
    SENIOR = 'SR'
    GRADUATE = 'GR'
    YEAR_IN_SCHOOL_CHOICES = [
        (FRESHMAN, 'Freshman'),
        (SOPHOMORE, 'Sophomore'),
        (JUNIOR, 'Junior'),
        (SENIOR, 'Senior'),
        (GRADUATE, 'Graduate'),
    ]
    year_in_school = models.CharField(

$myArray = array(
    2 => '3th element',

echo min(array_keys($myArray)); // return 1

In PHP, If your network under proxy. You should set the proxy URL and port

curl_setopt($ch, CURLOPT_PROXY, "http://url.com"); //your proxy url
curl_setopt($ch, CURLOPT_PROXYPORT, "80"); // your proxy port number

This is solves my problem

=IF(ISNUMBER(SEARCH(LEFT(H2,3),I2)),"YES","NO")))

The one poit I've noticed to be "the double edged sword" is:

placing the logic in hands of non technical staff

I've seen this work great, when you have one or two multidisciplinary geniuses on the non technical side, but I've also seen the lack of technicity leading to bloat, more bugs, and in general 4x the development/maintenance cost.

Thus you need to consider your user-base seriously.

You can write a very elegant solution using a functional style.

class Object
  def hashify
    Hash[instance_variables.map { |v| [v.to_s[1..-1].to_sym, instance_variable_get v] }]
  end
end

My users are allowed to upload CSV files and text/csv and application/csv did not appear by now. These are the ones identified through finfo():

If you are using only the default javax.xml package, you could set the JAXB_FRAGMENT option of the marshaller to 'true' (this omits the default xml processing instruction) and use the writeProcessingInstruction method of the XMLStreamWriter to insert your own:

xmlStreamWriter.writeProcessingInstruction("xml", "version=\"1.0\" encoding=\"UTF-8\"");
jaxbMarshaller.setProperty( Marshaller.JAXB_FRAGMENT, Boolean.TRUE);
jaxbMarshaller.marshal(object, xmlStreamWriter);
xmlStreamWriter.writeEndDocument();

brew install gradle

In short that will save time :) Ionic team please fix this

I was able to convert using below method for my WebAPI:

[HttpPost]
public HttpResponseMessage Post(dynamic item) // Passing parameter as dynamic
{
JArray itemArray = item["Region"]; // You need to add JSON.NET library
JObject obj = itemArray[0] as JObject;  // Converting from JArray to JObject
Region objRegion = obj.ToObject<Region>(); // Converting to Region object
}

You can use the bootstrap template from

http://www.initializr.com/

which includes all the bootstrap .less files. You can then change variables / update the less files as you want and it will automatically compile the css. When deploying compile the less file to css.

You can easily restart your MySql service. This kicks the error off.

A simple example of set cookie in your browser:

            $(function() {

               if ($.cookie('cookieStore')) {
                    var data=JSON.parse($.cookie("cookieStore"));
                    $('#name').text(data[0]);
                    $('#address').text(data[1]);
              }

              $('#submit').on('click', function(){

                    var storeData = new Array();
                    storeData[0] = $('#inputName').val();
                    storeData[1] = $('#inputAddress').val();

                    $.cookie("cookieStore", JSON.stringify(storeData));

                    $('#name').text(data[0]);
                    $('#address').text(data[1]);
              });
            });

Simple just copy/paste and use this code for set your cookie.

var checkedString = $('input:checkbox:checked.name').map(function() { return this.value; }).get().join();

The percentage % sign followed by two hexadecimal numbers (UTF-8 character representation) typically denotes a string which has been encoded to be part of a URI. This ensures that characters that would otherwise have special meaning don't interfere. In your case %20 is immediately recognisable as a whitespace character - while not really having any meaning in a URI it is encoded in order to avoid breaking the string into multiple "parts".

Don't get me wrong, regex is the bomb! However any web technology worth caring about will already have tools available in it's library to handle standards like this for you. Why re-invent the wheel...?

var str = 'xPasswords%20do%20not%20match';
console.log( decodeURI(str) ); // "xPasswords do not match"

Javascript has both decodeURI and decodeURIComponent which differ slightly in respect to their encodeURI and encodeURIComponent counterparts - you should familiarise yourself with the documentation.

Doctrine now has Criteria which offers a single API for filtering collections with SQL and in PHP, depending on the context.

https://www.doctrine-project.org/projects/doctrine-orm/en/latest/reference/working-with-associations.html#filtering-collections

Update

This will achieve the result in the accepted answer, without getting everything from the database.

use Doctrine\Common\Collections\Criteria;

/**
 * @ORM\Entity
 */
class Member {
  // ...
  public function getCommentsFiltered($ids) {
    $criteria = Criteria::create()->where(Criteria::expr()->in("id", $ids));

    return $this->getComments()->matching($criteria); 
  }
}

I talk about what \b-style regex boundaries actually are here.

The short story is that they’re conditional. Their behavior depends on what they’re next to.

# same as using a \b before:
(?(?=\w) (?<!\w)  | (?<!\W) )

# same as using a \b after:
(?(?<=\w) (?!\w)  | (?!\W)  )

Sometimes that isn’t what you want. See my other answer for elaboration.

For someone who needs quick reference of C# Escape Sequences that can be used in string literals:

\t     Horizontal tab (ASCII code value: 9)

\n     Line feed (ASCII code value: 10)

\r     Carriage return (ASCII code value: 13)

\'     Single quotation mark

\"     Double quotation mark

\\     Backslash

\?     Literal question mark

\x12     ASCII character in hexadecimal notation (e.g. for 0x12)

\x1234     Unicode character in hexadecimal notation (e.g. for 0x1234)

It's worth mentioning that these (in most cases) are universal codes. So \t is 9 and \n is 10 char value on Windows and Linux. But newline sequence is not universal. On Windows it's \n\r and on Linux it's just \n. That's why it's best to use Environment.Newline which gets adjusted to current OS settings. With .Net Core it gets really important.

Just do this element.remove();

I had the exact same problem while trying to setup a Gitlab pipeline executed by a Docker runner installed on a Raspberry Pi 4

Using nload to follow bandwidth usage within Docker runner container while pipeline was cloning the repo i saw the network usage dropped down to a few bytes per seconds..

After a some deeper investigations i figured out that the Raspberry temperature was too high and the network card start to dysfunction above 50° Celsius.

Adding a fan to my Raspberry solved the issue.

Very simple. Just follow these procedure:
1. git status
2. git add {File_Name} //the file name you haven been changed
3. git status
4. git commit -m '{your_message}'
5. git push origin master

Use an array, not a string, as given as guidance in BashFAQ #50.

Using a string is extremely bad security practice: Consider the case where password (or a where clause in the query, or any other component) is user-provided; you don't want to eval a password containing $(rm -rf .)!

Just Running A Local Command

variable declares and call like this in a class

class X {
    var x: Int = 3

}
var y = X()
print("value of x is: ", y.x)

//value of x is:  3

now you want to program to make the default value of x more than or equal to 3. Now take the hypothetical case if x is less than 3, your program will fail. so, you want people to either put 3 or more than 3. Swift got it easy for you and it is important to understand this bit-advance way of dating the variable value because they will extensively use in iOS development. Now let's see how get and set will be used here.

class X {
    var _x: Int = 3
    var x: Int {
        get {
            return _x
        }
        set(newVal) {  //set always take 1 argument
            if newVal >= 3 {
             _x = newVal //updating _x with the input value by the user
            print("new value is: ", _x)
            }
            else {
                print("error must be greater than 3")
            }
        }
    }
}
let y = X()
y.x = 1
print(y.x) //error must be greater than 3
y.x = 8 // //new value is: 8

if you still have doubts, just remember, the use of get and set is to update any variable the way we want it to be updated. get and set will give you better control to rule your logic. Powerful tool hence not easily understandable.

We can also use regular expression (/^([\w.-]+)@([\w-]+)((.(\w){2,3})+)$/i) to validate email address format is correct or not.

var emailRegex = new RegExp(/^([\w\.\-]+)@([\w\-]+)((\.(\w){2,3})+)$/i);
 var valid = emailRegex.test(emailAddress);
  if (!valid) {
    alert("Invalid e-mail address");
    return false;
  } else
    return true;

In some cases it is critical to perform a more in-depth debugging to the problem before stopping a container or killing a process.

Consider following the checklist below:

1) Check you current docker compose environment
Run docker-compose ps.
If port is in use by another container, stop it with docker-compose stop <service-name-in-compose-file> or remove it by replacing stop with rm.

2) Check the containers running outside your current workspace
Run docker ps to see list of all containers running under your host.
If you find the port is in use by another container, you can stop it with docker stop <container-id>.
(*) Because you're not under the scope of the origin compose environment - it is a good practice first to use docker inspect to gather more information about the container that you're about to stop.

3) Check if port is used by other processes running on the host
For example if the port is 6379 run:

$ sudo netstat -ltnp | grep ':6379'
tcp        0      0 127.0.0.1:6379          0.0.0.0:*               LISTEN      915/redis-server 12 
tcp6       0      0 ::1:6379                :::*                    LISTEN      915/redis-server 12

(*) You can also use the lsof command which is mainly used to retrieve information about files that are opened by various processes (I suggest running netstat before that).

So, In case of the output above the PID is 915. Now you can run:

$ ps j 915
 PPID   PID  PGID   SID TTY      TPGID STAT   UID   TIME COMMAND
    1   915   915   915 ?           -1 Ssl    123   0:11 /usr/bin/redis-server 127.0.0.1:6379

And see the ID of the parent process (PPID) and the execution command.
You can also run: $ pstree -s <PID> to a visual display of the process and its related processes.

In our case we can see that the process probably is a daemon (PPID is 1) - In that case consider running:
A) $ cat /proc/<PID>/status in order to get a more in-depth information about the process like the number of threads spawned by the process, its capabilities, etc'.
B) $ systemctl status <PID> in order to see the systemd unit that caused the creation of a specific process. If the service is not critical - you can stop and disable the service.

4) Restart Docker service
Run: sudo service docker restart.

5) You reached this point and..
Only if its not placing your system at risk - consider restarting the server.

The "Getting Started" page is the introduction to the documentation. Most documentation will start off with installation instructions, just like Composer's do.

The page that contains information on the composer.json file is located here - under "Basic Usage", the second page.

I'd recommend reading over the documentation in full, so that you gain a better understanding of how to use Composer. I'd also recommend removing what you have and following the installation instructions provided in the documentation.

Here's the mysql reference for cursors. So I'm guessing it's something like this:

  DECLARE done INT DEFAULT 0;
  DECLARE products_id INT;
  DECLARE result varchar(4000);
  DECLARE cur1 CURSOR FOR SELECT products_id FROM sets_products WHERE set_id = 1;
  DECLARE CONTINUE HANDLER FOR NOT FOUND SET done = 1;

  OPEN cur1;

  REPEAT
    FETCH cur1 INTO products_id;
    IF NOT done THEN
      CALL generate_parameter_list(@product_id, @result);
      SET param = param + "," + result; -- not sure on this syntax
    END IF;
  UNTIL done END REPEAT;

  CLOSE cur1;

  -- now trim off the trailing , if desired

I'm not sure why you'd want to validate an optional email address, but I'd suggest you use

^$|^[^@\s]+@[^@\s]+$

meaning

^$        empty string
|         or
^         beginning of string
[^@\s]+   any character but @ or whitespace
@         
[^@\s]+
$         end of string

You won't stop fake emails anyway, and this way you won't stop valid addresses.

If SESSION_START_DATE_TIME is of type TIMESTAMP you may want to try using the SQL function TO_TIMESTAMP. Here is an example:

     SQL> CREATE TABLE t (ts TIMESTAMP);

     Table created.

     SQL> INSERT INTO t
       2       VALUES (
       3                 TO_TIMESTAMP (
       4                    '1/12/2012 5:03:27.221008 PM'
       5                   ,'mm/dd/yyyy HH:MI:SS.FF AM'
       6                 )
       7              );

     1 row created.

     SQL> SELECT *
       2    FROM t
       3   WHERE ts =
       4            TO_TIMESTAMP (
       5               '1/12/2012 5:03:27.221008 PM'
       6              ,'mm/dd/yyyy HH:MI:SS.FF AM'
       7            );

Import JSON/CSV file in MongoDB

• wait wait
• first check mongoimport.exe file in your bin folder(C:\Program Files\MongoDB\Server\4.4\bin) if it is not then download mongodb database tools(https://www.mongodb.com/try/download/database-tools)
• copy extracted(unzip) files(inside unzipped bin) to bin folder(C:\Program Files\MongoDB\Server\4.4\bin)
• copy your json file to bin folder(C:\Program Files\MongoDB\Server\4.4\bin)
• Now open your commond prompt change its directory to bin

cd "C:\Program Files\MongoDB\Server\4.4\bin"

• Now copy this on your commnad prompt

mongoimport -d tymongo -c test --type json --file restaurants.json

• where d- database(tymongo-database name), c-collection(test-collection name)

FOR CSV FILE

 mongoimport -d tymongo -c test --type csv --file database2.csv --headerline

if you used List object and passed to the adapter you can remove the value from the List object and than call the notifyDataSetChanged() using adapter object.

for e.g.

List<String> list = new ArrayList<String>();
ArrayAdapter adapter;


adapter = new ArrayAdapter<String>(DeleteManyTask.this, 
            android.R.layout.simple_list_item_1,
            (String[])list.toArray(new String[0]));

listview = (ListView) findViewById(R.id.list);
listview.setAdapter(adapter);

listview.setAdapter(listAdapter);

for remove do this way

list.remove(index); //or
list.clear();
adpater.notifyDataSetChanged();

or without list object remove item from list.

adapter.clear();
adpater.notifyDataSetChanged();

You could even do it like this:

Example

grep -rl 'windows' ./ | xargs sed -i 's/windows/linux/g'

This will search for the string 'windows' in all files relative to the current directory and replace 'windows' with 'linux' for each occurrence of the string in each file.

td.description {vertical-align: top;}

where description is the class name of the td with that text in it

td.description {_x000D_
  vertical-align: top;_x000D_
}

<td class="description">Description</td>

OR inline (yuk!)

<td style="vertical-align: top;">Description</td>

What Facebook used is not the default password and alias for debug. You need to change it following and it will work.

/usr/lib/jvm/jdk1.8.0_66/bin/keytool -exportcert -alias androiddebugkey -keystore ~/.android/debug.keystore | openssl sha1 -binary | openssl base64

If you have not changed anything with the default password it should be "android".

You can also configure it in the build.gradle file. But the same alias password should be used for generating the hash:

android {
    signingConfigs {
        release {
            storeFile file("~/.android/debug.keystore")
            storePassword "android"
            keyAlias "androiddebugkey"
            keyPassword "android"
        }
    }
}

Joshc's answer was on the right track, but I found that it totally deletes the ?rel=0 querystring and replaces it with the ?wmode=transparent item - which has the effect of displaying the YouTube Suggested Videos list at the end of the playback, even though you originally didn't want this to happen.

I changed the code so that the src attribute of the embedded video is scanned first, to see if there is a question mark ? in it already (because this denotes the presence of a pre-existing query string, which might be something like ?rel=0 but could in theory be anything that YouTube choose to append in the future). If there's a query string already there, we want to preserve it, not destroy it, because it represents a setting chosen by whoever pasted in this YouTube video, and they presumably chose it for a reason!

So, if ? is found, the wmode=transparent will be appended using the format: &mode=transparent to just tag it on the end of the pre-existing query string.

If no ? is found, then the code will work in exactly the same way as it did originally (in toomanyairmiles's post), appending just ?wmode=transparent as a new query string to the URL.

Now, regardless of what may or may not be on the end of the YouTube URL as a query string already, it gets preserved, and the required wmode parameters get injected or added without damage to what was there before.

Here's the code to drop into your document.ready function:

$('iframe').each(function() {
  var url = $(this).attr("src");
  if (url.indexOf("?") > 0) {
    $(this).attr({
      "src" : url + "&wmode=transparent",
      "wmode" : "opaque"
    });
  }
  else {
    $(this).attr({
      "src" : url + "?wmode=transparent",
      "wmode" : "opaque"
    });
  }
});

@Override
public void onClick(View v)
{
    // TODO Auto-generated method stub
    Intent intent = new Intent(Activity1.this,Activity2.class);
    startActivity(intent);

}

First - do not edit anything in your gem path! It will influence all projects, and you will have a lot problems later...

In your project edit script/rails this way:

#!/usr/bin/env ruby
# This command will automatically be run when you run "rails" with Rails 3 gems installed from the root of your application.

APP_PATH = File.expand_path('../../config/application',  __FILE__)
require File.expand_path('../../config/boot',  __FILE__)

# THIS IS NEW:
require "rails/commands/server"
module Rails
  class Server
    def default_options
      super.merge({
        :Port        => 10524,
        :environment => (ENV['RAILS_ENV'] || "development").dup,
        :daemonize   => false,
        :debugger    => false,
        :pid         => File.expand_path("tmp/pids/server.pid"),
        :config      => File.expand_path("config.ru")
      })
    end
  end
end
# END OF CHANGE
require 'rails/commands'

The principle is simple - you are monkey-patching the server runner - so it will influence just one project.

UPDATE: Yes, I know that the there is simpler solution with bash script containing:

#!/bin/bash
rails server -p 10524

but this solution has a serious drawback - it is boring as hell.

I would like to make a little bit more emphasis on some key differences between res.end() & res.send() with respect to response headers and why they are important.

1. res.send() will check the structure of your output and set header information accordingly.

    app.get('/',(req,res)=>{
       res.send('<b>hello</b>');
    });

     app.get('/',(req,res)=>{
         res.send({msg:'hello'});
     });

Where with res.end() you can only respond with text and it will not set "Content-Type"

      app.get('/',(req,res)=>{
           res.end('<b>hello</b>');
      }); 

2. res.send() will set "ETag" attribute in the response header

      app.get('/',(req,res)=>{
            res.send('<b>hello</b>');
      });

¿Why is this tag important?
The ETag HTTP response header is an identifier for a specific version of a resource. It allows caches to be more efficient, and saves bandwidth, as a web server does not need to send a full response if the content has not changed.

res.end() will NOT set this header attribute

I've gotten around this with

mystr = ' '.join(
        ["Why, hello there",
         "wonderful stackoverflow people!"])

in the past. It's not perfect, but it works nicely for very long strings that need to not have line breaks in them.

Try to use this composed of two steps command:

rm -rf bar && cp -r foo bar

I think the blow code will help you, and add those code before setContentView()

getWindow().setFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS, WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);

Add those code behind setContentView() getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LOW_PROFILE);

It's better to do this.

Navigate to the folder structure you require

Use the command

jar -xvf  'Path_to_ur_Jar_file'

Try setting the disabled attribute directly:

if ( someCondition == true ) {
   document.getElementById('btn1').setAttribute('disabled', 'disabled');
} else {
   document.getElementById('btn1').removeAttribute('disabled');
}

While the above answers work but in case you have multiple devices connected to your computer then the following command can be used to remove the app from one of them:

adb -s <device-serial> shell pm uninstall <app-package-name>

If you want to find out the device serial then use the following command:

adb devices -l

This will give you a list of devices attached. The left column shows the device serials.

Another way which could make sense for the given situation is

BigDecimal newBD = oldBD.setScale(2);

I just say this because in some cases when it comes to money going beyond 2 decimal places does not make sense. Taking this a step further, this could lead to

String displayString = oldBD.setScale(2).toPlainString();

but I merely wanted to highlight the setScale method (which can also take a second rounding mode argument to control how that last decimal place is handled. In some situations, Java forces you to specify this rounding method).

You are not indicating what to include in the archive.

Go one level outside your folder and try:

sudo tar -cvjSf folder.tar.bz2 folder

Or from the same folder try

sudo tar -cvjSf folder.tar.bz2 *

Cheers!

There is a gcc extension which allows lambda templates:

// create the widgets and set the label
base::for_each(_widgets, [] <typename Key_T, typename Widget_T>
                         (boost::fusion::pair<Key_T, Widget_T*>& pair) -> void {
                             pair.second = new Widget_T();
                             pair.second->set_label_str(Key_T::label);
                          }
              );

where _widgets is a std::tuple< fusion::pair<Key_T, Widget_T>... >

In the START menu type "regedit" to open the Registry editor

Go to "HKEY_LOCAL_MACHINE" on the left-hand side registry explorer/tree menu

Click "SOFTWARE" within the "HKEY_LOCAL_MACHINE" registries

Click "JavaSoft" within the "SOFTWARE" registries

Click "Java Runtime Environment" within the "JavaSoft" list of registries here you can see different versions of installed java

Click "Java Runtime Environment"- On right hand side you will get 4-5 rows . Please select "CurrentVersion" and right Click( select modify option) Change version to "1.7"

Now the magic has been completed

pip3 not pip. You can create an alias like you did with python3 if you like.

For Chart.js 2.*, the option for the scale to begin at zero is listed under the configuration options of the linear scale. This is used for numerical data, which should most probably be the case for your y-axis. So, you need to use this:

options: {
    scales: {
        yAxes: [{
            ticks: {
                beginAtZero: true
            }
        }]
    }
}

A sample line chart is also available here where the option is used for the y-axis. If your numerical data is on the x-axis, use xAxes instead of yAxes. Note that an array (and plural) is used for yAxes (or xAxes), because you may as well have multiple axes.

I forgot to select Microsoft Office Developer Tools for installation initially. In my case Visual Studio Professional 2013 and also 2015.

I wrote a VBA file to add a tool cleaning these abnormally biggest file. This script clear all columns and rows after the last cells realy used to reset the last cells ( [Ctrl]+[End] ), and it also provides enable images compression.

I dev an AddIns with auto install (just run it with macro enabled) to include in context menu many new buttons:

1. Optimize
2. Optimize and Save
3. Disable Optimizer

This is based on KB of Microsoft office 2003 and answer of PP. with personals improvement :

1. add compression of images
2. fix bug for Columns
3. feat compatibility with excel 2007 - 2010 - ... (more than 255 columns)

This should work too:

logging.Formatter(fmt='%(asctime)s.%(msecs)03d',datefmt='%Y-%m-%d,%H:%M:%S')

You could default the parameter to null or false.
This way, it would be shorter to test if a value has been passed as parameter.

@mixin clearfix($width: null) {

  @if not ($width) {

    // if width is not passed, or empty do this

  } @else {

    display: inline-block;
    width: $width;

  }
}

Within the parent, you can reference the child using @ViewChild. When needed (i.e. when the event would be fired), you can just execute a method in the child from the parent using the @ViewChild reference.

Quoting MSDN:

When SET XACT_ABORT is ON, if a Transact-SQL statement raises a run-time error, the entire transaction is terminated and rolled back. When SET XACT_ABORT is OFF, in some cases only the Transact-SQL statement that raised the error is rolled back and the transaction continues processing.

In practice this means that some of the statements might fail, leaving the transaction 'partially completed', and there might be no sign of this failure for a caller.

A simple example:

INSERT INTO t1 VALUES (1/0)    
INSERT INTO t2 VALUES (1/1)    
SELECT 'Everything is fine'

This code would execute 'successfully' with XACT_ABORT OFF, and will terminate with an error with XACT_ABORT ON ('INSERT INTO t2' will not be executed, and a client application will raise an exception).

As a more flexible approach, you could check @@ERROR after each statement (old school), or use TRY...CATCH blocks (MSSQL2005+). Personally I prefer to set XACT_ABORT ON whenever there is no reason for some advanced error handling.

FormHelper::select(string $fieldName, array $options, 
array $attributes)

$attributes['value'] to set which value should be selected default

<?php echo $this->Form->select('status', $list, array(

    'value' => 1)
); ?>

Use set_index with stack for MultiIndex Series, then for DataFrame add reset_index with rename:

df1 = (df.set_index(["location", "name"])
         .stack()
         .reset_index(name='Value')
         .rename(columns={'level_2':'Date'}))
print (df1)
  location  name        Date  Value

As of Java 11 one can use Pattern#asMatchPredicate which returns Predicate<String>.

String string = "stores%store%product";
String regex = "stores.*store.*product.*";
Predicate<String> matchesRegex = Pattern.compile(regex).asMatchPredicate();

boolean match = matchesRegex.test(string);                   // true

The method enables chaining with other String predicates, which is the main advantage of this method as long as the Predicate offers and, or and negate methods.

String string = "stores$store$product";
String regex = "stores.*store.*product.*";

Predicate<String> matchesRegex = Pattern.compile(regex).asMatchPredicate();
Predicate<String> hasLength = s -> s.length() > 20;

boolean match = hasLength.and(matchesRegex).test(string);    // false

according to GSON User guide, you cannot.

Collections Limitations

Can serialize collection of arbitrary objects but can not deserialize from it. Because there is no way for the user to indicate the type of the resulting object

Off hand the code looks right. What if you try using an 'Else' and see what happens?

IF @SchoolCategoryCode = 'Elem' 

--- We now have determined we are processing an elementary school...

BEGIN

---- Only do the following if the variable @Term equals a 3 - if it does not, skip just this first part

    IF @Term = 3
    BEGIN
        INSERT INTO @Classes

        SELECT              
            XXXXXX  
        FROM XXXX blah blah blah

        INSERT INTO @Classes    
        SELECT
        XXXXXXXX    
        FROM XXXXXX (more code) 
    END   <----(Should this be ENDIF?)
    ELSE
    BEGIN


        INSERT INTO @Classes    
        SELECT
        XXXXXXXX    
        FROM XXXXXX (more code) 
    END
END

first you can check console.log(typeof Object)

if the output is object then var {data}=object ie just destructure the object according to the object keys. and the function can be like this.

const abc=(str1,str2=null)=>{


     var result=[];
      result.push(str1);result.push(str2);
      return result.join("");

}

if you include the / at the start of the include, the include will be taken as the path from the root of the site.

if your site is http://www.example.com/game/forum/files/index.php you can add an include to /includes/boot.inc.php which would resolve to http://www.example.com/includes/boot.inc.php .

You have to be careful with .. traversal as some web servers have it disabled; it also causes problems when you want to move your site to a new machine/host and the structure is a little different.

By using display: inline-block; And more generally when you have a parent (always there is a parent except for html) use display: inline-block; for the inner elements. and to force them to stay in the same line even when the window get shrunk (contracted). Add for the parent the two property:

    white-space: nowrap;
    overflow-x: auto;

here a more formatted example to make it clear:

.parent {
    white-space: nowrap;
    overflow-x: auto;
}

.children {
   display: inline-block;
   margin-left: 20px; 
}

For this example particularly, you can apply the above as fellow (i'm supposing the parent is body. if not you put the right parent), you can also like change the html and add a parent for them if it's possible.

body { /*body may pose problem depend on you context, there is no better then have a specific parent*/
        white-space: nowrap;
        overflow-x: auto;
 }

#element1, #element2{ /*you can like put each one separately, if the margin for the first element is not wanted*/
   display: inline-block;
   margin-left: 10px; 
}

keep in mind that white-space: nowrap; and overlow-x: auto; is what you need to force them to be in one line. white-space: nowrap; disable wrapping. And overlow-x:auto; to activate scrolling, when the element get over the frame limit.

Scikit learn plays really well with Pandas, so I suggest you use it. Here's an example:

In [1]: 
import pandas as pd
import numpy as np
from sklearn.model_selection import train_test_split
data = np.reshape(np.random.randn(20),(10,2)) # 10 training examples
labels = np.random.randint(2, size=10) # 10 labels

In [2]: # Giving columns in X a name
X = pd.DataFrame(data, columns=['Column_1', 'Column_2'])
y = pd.Series(labels)

In [3]:
X_train, X_test, y_train, y_test = train_test_split(X, y, 
                                                    test_size=0.2, 
                                                    random_state=0)

In [4]: X_test
Out[4]:

     Column_1    Column_2
2   -1.39       -1.86
8    0.48       -0.81
4   -0.10       -1.83

In [5]: y_test
Out[5]:

2    1
8    1
4    1
dtype: int32

You can directly call any scikit functions on DataFrame/Series and it will work.

Let's say you wanted to do a LogisticRegression, here's how you could retrieve the coefficients in a nice way:

In [6]: 
from sklearn.linear_model import LogisticRegression

model = LogisticRegression()
model = model.fit(X_train, y_train)

# Retrieve coefficients: index is the feature name (['Column_1', 'Column_2'] here)
df_coefs = pd.DataFrame(model.coef_[0], index=X.columns, columns = ['Coefficient'])
df_coefs
Out[6]:
            Coefficient
Column_1    0.076987
Column_2    -0.352463

$("#birthdate" ).datepicker("setDate", new Date(1985,01,01))

Try adding log_errors = Off and check the error_reporting setting whether it's set high enough.

Here's a one-liner using sschober's tool.

$ while true; do kqwait ./file-to-watch.js; script-to-execute.sh; done

IEquatable<T> can be a much easier way to do this with modern frameworks.

You get a nice simple bool Equals(T other) function and there's no messing around with casting or creating a separate class.

public class Person : IEquatable<Person>
{
    public Person(string name, string hometown)
    {
        this.Name = name;
        this.Hometown = hometown;
    }

    public string Name { get; set; }
    public string Hometown { get; set; }

    // can't get much simpler than this!
    public bool Equals(Person other)
    {
        return this.Name == other.Name && this.Hometown == other.Hometown;
    }

    public override int GetHashCode()
    {
        return Name.GetHashCode();  // see other links for hashcode guidance 
    }
}

Note you DO have to implement GetHashCode if using this in a dictionary or with something like Distinct.

PS. I don't think any custom Equals methods work with entity framework directly on the database side (I think you know this because you do AsEnumerable) but this is a much simpler method to do a simple Equals for the general case.

If things don't seem to be working (such as duplicate key errors when doing ToDictionary) put a breakpoint inside Equals to make sure it's being hit and make sure you have GetHashCode defined (with override keyword).

I needed a regular 10 GB file for testing, so I couldn't use fsutil because it creates sparse files (thanks @ZXX).

@echo off

:: Create file with 2 bytes
echo.>file-big.txt

:: Expand to 1 KB
for /L %%i in (1, 1, 9) do type file-big.txt>>file-big.txt

:: Expand to 1 MB
for /L %%i in (1, 1, 10) do type file-big.txt>>file-big.txt

:: Expand to 1 GB
for /L %%i in (1, 1, 10) do type file-big.txt>>file-big.txt

:: Expand to 4 GB
del file-4gb.txt
for /L %%i in (1, 1, 4) do type file-big.txt>>file-4gb.txt

del file-big.txt

I wanted to create a 10 GB file, but for some reason it only showed up as 4 GB, so I wanted to be safe and stopped at 4 GB. If you really want to be sure your file will be handled properly by the operating system and other applications, stop expanding it at 1 GB.

Late answer but showing one more possibility...

Cumulative Sum generation can be more optimized with the CROSS APPLY logic.

Works better than the INNER JOIN & OVER Clause when analyzed the actual query plan ...

/* Create table & populate data */

If you want to use both the simple click and long click on list view items better way to implement that would be to use context menu for long click. Avoid using setItemLongClickListener especially if you have multiple row layouts for your listview.

The Groovy script you provided is formatting the first line as a blank line in the resultant script. The shebang, telling the script to run with /bin/bash instead of /bin/sh, needs to be on the first line of the file or it will be ignored.

So instead, you should format your Groovy like this:

stage('Setting the variables values') {
    steps {
         sh '''#!/bin/bash
                 echo "hello world" 
         '''
    }
}

And it will execute with /bin/bash.

If you want multiple messages from a queue, say 10 messages, the command to use is:

rabbitmqadmin get queue=<QueueName> ackmode=ack_requeue_true count=10

If you don't want the messages requeued, just change ackmode to ack_requeue_false.

Using OVER() and LIMIT 1:

SELECT COUNT(1) OVER()
FROM posts 
   INNER JOIN votes ON votes.post_id = posts.id 
GROUP BY posts.id
LIMIT 1;

INSERT INTO test VALUES('a line\nanother line');

\n just works fine here

Use Below Code instead of your code

<EditText 
    android:id="@+id/searchbox"  
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:maxLines="1"
    android:inputType="text"
    android:scrollHorizontally="true"
    android:ellipsize="end"
    android:layout_weight="1"
    android:layout_marginTop="2dp"
    android:drawablePadding="10dp"
    android:background="@drawable/edittext"
    android:drawableLeft="@drawable/folder_full"
    android:drawableRight="@drawable/search"
    android:paddingLeft="15dp"
    android:hint="search..."/>

I suppose this depends on your architecture and whatever else you may need to consider, but you could also take the object-oriented approach and use a class.

class ClassName {

    private $site_url;

    function __construct( $url ) {
        $this->site_url = $url;
    }

    public function parts( string $part ) {
        echo 'http://' . $this->site_url . 'content/' . $part . '.php';
    }

    # You could build a bunch of other things here
    # too and still have access to $this->site_url.
}

Then you can create and use the object wherever you'd like.

$obj = new ClassName($site_url);
$obj->parts('part_argument');

This could be overkill for what OP was specifically trying to achieve, but it's at least an option I wanted to put on the table for newcomers since nobody mentioned it yet.

The advantage here is scalability and containment. For example, if you find yourself needing to pass the same variables as references to multiple functions for the sake of a common task, that could be an indicator that a class is in order.

9.3 Context per request

Entity Framework’s contexts are meant to be used as short-lived instances in order to provide the most optimal performance experience. Contexts are expected to be short lived and discarded, and as such have been implemented to be very lightweight and reutilize metadata whenever possible. In web scenarios it’s important to keep this in mind and not have a context for more than the duration of a single request. Similarly, in non-web scenarios, context should be discarded based on your understanding of the different levels of caching in the Entity Framework. Generally speaking, one should avoid having a context instance throughout the life of the application, as well as contexts per thread and static contexts.

Try this:

select * from your_table
where date >= '2020-10-01'  

You need to check for status 0 (as when loading files locally with XMLHttpRequest, you don't get a status and if it is from web server it returns the status)

function readTextFile(file) {
var rawFile = new XMLHttpRequest();
rawFile.open("GET", file, false);
rawFile.onreadystatechange = function ()
{
    if(rawFile.readyState === 4)
    {
        if(rawFile.status === 200 || rawFile.status == 0)
        {
            var allText = rawFile.responseText;
            alert(allText);
        }
    }
}
rawFile.send(null);

}

For device file readuing use this:

readTextFile("file:///C:/your/path/to/file.txt");

For file reading from server use:

readTextFile("http://test/file.txt");

This worked for me every time, inspired by Craig Ringer:

brew install proctools
sudo pkill -u postgres

proctools includes pkill. If you don't have Homebrew: https://brew.sh/

Use Ctrl + Alt + F combination in Ubuntu.

Try Portable UTF-8:

$str = utf8_chr( 0x1000 );
$str = utf8_chr( '\u1000' );
$str = utf8_chr( 4096 );

All work exactly the same way. You can get the codepoint of a character with utf8_ord(). Read more about Portable UTF-8.

You need to encode Unicode explicitly before writing to a file, otherwise Python does it for you with the default ASCII codec.

Pick an encoding and stick with it:

f.write(printinfo.encode('utf8') + '\n')

or use io.open() to create a file object that'll encode for you as you write to the file:

import io

f = io.open(filename, 'w', encoding='utf8')

Here's what Oracle's documentation has to say:

By default the heap dump is created in a file called java_pid.hprof in the working directory of the VM, as in the example above. You can specify an alternative file name or directory with the -XX:HeapDumpPath= option. For example -XX:HeapDumpPath=/disk2/dumps will cause the heap dump to be generated in the /disk2/dumps directory.

This worked for me with 5 images in diferent sizes.

1. Create a container div
2. An Unordered list for the images
3. On css the unordened must be displayed vertically and without bullets
4. Justify content of container div

This works because of justify-content:space-between, and it's on a list, displayed horizontally.

On CSS

 #container {
            display: flex;
            justify-content: space-between;
 }
    #container ul li{ display:inline; list-style-type:none;
}

On html

<div id="container"> 
  <ul>  
        <li><img src="box1.png"><li>
        <li><img src="box2.png"><li>
        <li><img src="box3.png"><li>
        <li><img src="box4.png"><li>
        <li><img src="box5.png"><li>
    </ul>
</div>

You could just do it like this

$query_select = "SELECT * FROM shouts ORDER BY id DESC LIMIT 8;"; 

$result_select = mysql_query($query_select) or die(mysql_error());

 foreach($result_select as $row){
    $ename = stripslashes($row['name']);
    $eemail = stripcslashes($row['email']);
    $epost = stripslashes($row['post']);
    $eid = $row['id'];

    $grav_url = "http://www.gravatar.com/avatar.php?gravatar_id=".md5(strtolower($eemail))."&size=70";

    echo ('<img src = "' . $grav_url . '" alt="Gravatar">'.'<br/>');

    echo $eid . '<br/>';

    echo $ename . '<br/>';

    echo $eemail . '<br/>';

    echo $epost . '<br/><br/><br/><br/>';
 }

  appBar: new AppBar(title: new Text("SmartDocs SPAY"),backgroundColor: Colors.blueAccent, automaticallyImplyLeading:false,
        leading: new Container(),
      ),

It is working Fine

If you can't rename the module to match Python naming conventions, create a new module to act as an intermediary:

 ---- foo_proxy.py ----
 tmp = __import__('foo-bar')
 globals().update(vars(tmp))

 ---- main.py ----
 from foo_proxy import * 

I would use PowerShell instead!

To add a directory to PATH using PowerShell, do the following:

$PATH = [Environment]::GetEnvironmentVariable("PATH")
$xampp_path = "C:\xampp\php"
[Environment]::SetEnvironmentVariable("PATH", "$PATH;$xampp_path")

To set the variable for all users, machine-wide, the last line should be like:

[Environment]::SetEnvironmentVariable("PATH", "$PATH;$xampp_path", "Machine")

In a PowerShell script, you might want to check for the presence of your C:\xampp\php before adding to PATH (in case it has been previously added). You can wrap it in an if conditional.

So putting it all together:

$PATH = [Environment]::GetEnvironmentVariable("PATH", "Machine")
$xampp_path = "C:\xampp\php"
if( $PATH -notlike "*"+$xampp_path+"*" ){
    [Environment]::SetEnvironmentVariable("PATH", "$PATH;$xampp_path", "Machine")
}

Better still, one could create a generic function. Just supply the directory you wish to add:

function AddTo-Path{
param(
    [string]$Dir
)

    if( !(Test-Path $Dir) ){
        Write-warning "Supplied directory was not found!"
        return
    }
    $PATH = [Environment]::GetEnvironmentVariable("PATH", "Machine")
    if( $PATH -notlike "*"+$Dir+"*" ){
        [Environment]::SetEnvironmentVariable("PATH", "$PATH;$Dir", "Machine")
    }
}

You could make things better by doing some polishing. For example, using Test-Path to confirm that your directory actually exists.

If you need refresh, this is another posibility:

setTimeout(function () { 
    $("#jsSegurosProductos").jsGrid("refresh"); 
}, 1000);

You start by writing a class that derives from Attribute:

public class MyCustomAttribute: Attribute
{
    public string SomeProperty { get; set; }
}

Then you could decorate anything (class, method, property, ...) with this attribute:

[MyCustomAttribute(SomeProperty = "foo bar")]
public class Foo
{

}

and finally you would use reflection to fetch it:

var customAttributes = (MyCustomAttribute[])typeof(Foo).GetCustomAttributes(typeof(MyCustomAttribute), true);
if (customAttributes.Length > 0)
{
    var myAttribute = customAttributes[0];
    string value = myAttribute.SomeProperty;
    // TODO: Do something with the value
}

You could limit the target types to which this custom attribute could be applied using the AttributeUsage attribute:

/// <summary>
/// This attribute can only be applied to classes
/// </summary>
[AttributeUsage(AttributeTargets.Class)]
public class MyCustomAttribute : Attribute

Important things to know about attributes:

• Attributes are metadata.
• They are baked into the assembly at compile-time which has very serious implications of how you could set their properties. Only constant (known at compile time) values are accepted
• The only way to make any sense and usage of custom attributes is to use Reflection. So if you don't use reflection at runtime to fetch them and decorate something with a custom attribute don't expect much to happen.
• The time of creation of the attributes is non-deterministic. They are instantiated by the CLR and you have absolutely no control over it.

If you use VSCode, consider using the Angular Console

It provides an interface for the Angular CLI. You will see an option to specify the path.

The Angular CLI is immensely powerful and extensible. In fact, there are so many capabilities that it is helpful for developers to have all of the different configuration options for every command available to them.

With Angular Console, you’ll get recommendations and be able to pull up even the most easily forgotten or rarely used features!

Angular Console is, first and foremost, a more productive way to work with what the Angular CLI provides.

I believe that currently (5/1/2012), all major browsers support the outerHTML function. It seems to me that this snippet is sufficient. I personally would choose to memorize this:

// Gives you the DOM element without the outside wrapper you want
$('.classSelector').html()

// Gives you the outside wrapper as well only for the first element
$('.classSelector')[0].outerHTML

// Gives you the outer HTML for all the selected elements
var html = '';
$('.classSelector').each(function () {
    html += this.outerHTML;
});

//Or if you need a one liner for the previous code
$('.classSelector').get().map(function(v){return v.outerHTML}).join('');

EDIT: Basic support stats for element.outerHTML

If checked:

$( "SELECTOR" ).attr( "checked" )  // Returns ‘true’ if present on the element, returns undefined if not present
$( "SELECTOR" ).prop( "checked" ) // Returns true if checked, false if unchecked.
$( "SELECTOR" ).is( ":checked" ) // Returns true if checked, false if unchecked.

Get the checked val:

$( "SELECTOR:checked" ).val()

Get the checked val numbers:

$( "SELECTOR:checked" ).length

Check or uncheck checkbox

$( "SELECTOR" ).prop( "disabled", false );
$( "SELECTOR" ).prop( "checked", true );

I struggled with the idea of centralizing a global error handling routine in an MVC app before. I have a post on the ASP.NET forums.

It basically handles all your application errors in the global.asax without the need for an error controller, decorating with the [HandlerError] attribute, or fiddling with the customErrors node in the web.config.

// I use this jquery it works perfect, just add class nosonly to any textbox that should be numbers only:

$(document).ready(function () {
       $(".nosonly").keydown(function (event) {
           // Allow only backspace and delete
           if (event.keyCode == 46 || event.keyCode == 8) {
               // let it happen, don't do anything
           }
           else {
               // Ensure that it is a number and stop the keypress
               if (event.keyCode < 48 || event.keyCode > 57) {
              alert("Only Numbers Allowed"),event.preventDefault();
               }
           }
       });
   });
