You can add a style.css, import this file after the bootstrap.css to override this code.

For example:

/* bootstrap.css */
* {
   font-size: 14px;
   line-height: 1.428;
}

/* style.css */
* {
   font-size: 16px;
   line-height: 2;
}

Don't change bootstrap.css directly for better maintenance of code.

You could do:

std::tie(x, y) = std::make_pair(y, x);

Or use make_tuple when swapping more than two variables:

std::tie(x, y, z) = std::make_tuple(y, z, x);

But I'm not sure if internally std::tie uses a temporary variable or not!

Functions are another type of variable in JavaScript (with some nuances of course). Creating a function within another function changes the scope of the function in the same way it would change the scope of a variable. This is especially important for use with closures to reduce total global namespace pollution.

The functions defined within another function won't be accessible outside the function unless they have been attached to an object that is accessible outside the function:

function foo(doBar)
{
  function bar()
  {
    console.log( 'bar' );
  }

  function baz()
  {
    console.log( 'baz' );
  }

  window.baz = baz;
  if ( doBar ) bar();
}

In this example, the baz function will be available for use after the foo function has been run, as it's overridden window.baz. The bar function will not be available to any context other than scopes contained within the foo function.

as a different example:

function Fizz(qux)
{
  this.buzz = function(){
    console.log( qux );
  };
}

The Fizz function is designed as a constructor so that, when run, it assigns a buzz function to the newly created object.

403 - means I know who you are but you are not authorized to do what you asking.

In my case, the problem was in a Policy - I didn't choose an object when specified the Policy in Visual Editor

I find answer. Thanks all but right answer next:

$("#myModal").on("hidden", function () {
  $('#result').html('yes,result');
});

Events here http://bootstrap-ru.com/javascript.php#modals

UPD

For Bootstrap 3.x need use hidden.bs.modal:

$("#myModal").on("hidden.bs.modal", function () {
  $('#result').html('yes,result');
});

The problem is the 'table-layout:fixed' which create evenly-spaced-fixed-width columns. But disabling this css-property will kill the text-overflow because the table will become as large as possible (and than there is noting to overflow).

I'm sorry but in this case Fred can't have his cake and eat it to.. unless the landlord gives Celldito less space to work with in the first place, Fred cannot use his..

You are getting a table scan there, meaning that you do not have an index defined on er101_upd_date_iso, or if that column is part of an existing index, the index can't be used (possibly it is not the primary indexer column).

Adding missing indexes will help performance no end.

there are already indexs on the columns which are queried most commonly

That does not mean they are used in this query (and they probably are not).

I suggest reading Finding the Causes of Poor Performance in SQL Server by Gail Shaw, part 1 and part 2.

In my case I had two Constructors in the bean and I had the same error. I have just deleted one of them and now the issue is fixed!

May the div with id="content" not be created when this event is attached? You can try live() jquery method.

Else there may be multiple divs with the same id or you just spelled it wrong, it happens...

r = requests.get('https://api.github.com', auth=('user', 'pass'))

r is a response. It has a request attribute which has the information you need.

r.request.allow_redirects  r.request.headers          r.request.register_hook
r.request.auth             r.request.hooks            r.request.response
r.request.cert             r.request.method           r.request.send
r.request.config           r.request.params           r.request.sent
r.request.cookies          r.request.path_url         r.request.session
r.request.data             r.request.prefetch         r.request.timeout
r.request.deregister_hook  r.request.proxies          r.request.url
r.request.files            r.request.redirect         r.request.verify

r.request.headers gives the headers:

{'Accept': '*/*',
 'Accept-Encoding': 'identity, deflate, compress, gzip',
 'Authorization': u'Basic dXNlcjpwYXNz',
 'User-Agent': 'python-requests/0.12.1'}

Then r.request.data has the body as a mapping. You can convert this with urllib.urlencode if they prefer:

import urllib
b = r.request.data
encoded_body = urllib.urlencode(b)

depending on the type of the response the .data-attribute may be missing and a .body-attribute be there instead.

There seems to be an issue with select drop down controls not dynamically changing when the controls are dynamically created instead of being in a static HTML page.

In jQuery this solution worked for me.

$('#editAddMake').val(result.data.make_id);
$('#editAddMake').selectmenu('refresh');

Just as an addendum the first line of code without the second line, did actually work transparently in that, retrieving the selected index was correct after setting the index and if you actually clicked the control it would show the correct item but this didn't reflect in the top label of the control.

Hope this helps.

Above wait statement is a nice example of Explicit wait.

As Explicit waits are intelligent waits that are confined to a particular web element(as mentioned in above x-path).

By Using explicit waits you are basically telling WebDriver at the max it is to wait for X units(whatever you have given as timeoutInSeconds) of time before it gives up.

Here's what I cooked up. It's pretty simple, but it works:

function eventFire(el, etype){
  if (el.fireEvent) {
    el.fireEvent('on' + etype);
  } else {
    var evObj = document.createEvent('Events');
    evObj.initEvent(etype, true, false);
    el.dispatchEvent(evObj);
  }
}

Usage:

eventFire(document.getElementById('mytest1'), 'click');

That's now how PHP works. test() will execute when the page is loaded, not when the submit button is clicked.

To do this sort of thing, you have to have the onclick attribute do an AJAX call to a PHP file.

I resolved this by editing the svg file too.

I wrapped the xml of the whole svg graphic in a group tag that has a click event as follows:

<svg .....>
<g id="thefix" onclick="window.top.location.href='http://www.google.com/';">
 <!-- ... your graphics ... -->
</g>
</svg>

Solution works in all browsers that support object svg script. (default a img tag inside your object element for browsers that don't support svg and you'll cover the gamut of browsers)

Use DefinePlugin.

The DefinePlugin allows you to create global constants which can be configured at compile time.

new webpack.DefinePlugin(definitions)

Example:

plugins: [
  new webpack.DefinePlugin({
    PRODUCTION: JSON.stringify(true)
  })
  //...
]

Usage:

console.log(`Environment is in production: ${PRODUCTION}`);

Assembly code is a human readable representation of machine code:

mov eax, 77
jmp anywhere

Machine code is pure hexadecimal code:

5F 3A E3 F1

I assume you mean object code as in an object file. This is a variant of machine code, with a difference that the jumps are sort of parameterized such that a linker can fill them in.

An assembler is used to convert assembly code into machine code (object code) A linker links several object (and library) files to generate an executable.

I have once written an assembler program in pure hex (no assembler available) luckily this was way back on the good old (ancient) 6502. But I'm glad there are assemblers for the pentium opcodes.

In addition to @Malk, I wanted to clear all fields in the popup, except the hidden fields. To do that just use this:

$('.modal').on('hidden.bs.modal', function () {
    $(this)
        .find("input:not([type=hidden]),textarea,select")
        .val('')
        .end()
        .find("input[type=checkbox], input[type=radio]")
        .prop("checked", "")
        .end();
});

This will clear all fields, except the hidden ones.

string input = "OneTwoThree";
(if input.length >5)
{
string str=input.substring(input.length-5,5);
}

You can find those maven properties in the super pom.

You find the jar here:

${M2_HOME}/lib/maven-model-builder-3.0.3.jar

Open the jar with 7-zip or some other archiver (or use the jar tool).

Navigate to

org/apache/maven/model

There you'll find the pom-4.0.0.xml.

It contains all those "short cuts":

<project>
    ...
    <build>
        <directory>${project.basedir}/target</directory>
        <outputDirectory>${project.build.directory}/classes</outputDirectory>
        <finalName>${project.artifactId}-${project.version}</finalName>
        <testOutputDirectory>${project.build.directory}/test-classes</testOutputDirectory>
        <sourceDirectory>${project.basedir}/src/main/java</sourceDirectory>
        <scriptSourceDirectory>src/main/scripts</scriptSourceDirectory>
        <testSourceDirectory>${project.basedir}/src/test/java</testSourceDirectory>
        <resources>
            <resource>
                <directory>${project.basedir}/src/main/resources</directory>
            </resource>
        </resources>
        <testResources>
            <testResource>
                <directory>${project.basedir}/src/test/resources</directory>
            </testResource>
        </testResources>
        ...
    </build>
    ...
</project>

Update

After some lobbying I am adding a link to the pom-4.0.0.xml. This allows you to see the properties without opening up the local jar file.

MD5 is a bit old, SHA-1 is a better algorithm, there is a example here.

(Also as they note in that post, Java handles this on it's own, no Android specific code.)

Basically you need following things to make location detector android app

• Location Listener, which detect current location
• Marker to add and animate when person moves
• Polyline to add path on person's movement
• Services for sending and receiving location
• Rest API / Firebase Realtime Database to store and fetch locations

Now if you write each of these module yourself then it needs much time and efforts. So it would be better to use ready resources that are being maintained already.

Using all these resources, you will be able to create an flawless android location detection app.

1. Location Listening

You will first need to listen for current location of user. You can use any of below libraries to quick start.

Google Play Location Samples

This library provide last known location, location updates

Location Manager

With this library you just need to provide a Configuration object with your requirements, and you will receive a location or a fail reason with all the stuff are described above handled.

Live Location Sharing

Use this open source repo of the Hypertrack Live app to build live location sharing experience within your app within a few hours. HyperTrack Live app helps you share your Live Location with friends and family through your favorite messaging app when you are on the way to meet up. HyperTrack Live uses HyperTrack APIs and SDKs.

2. Markers Library

Google Maps Android API utility library

• Marker clustering — handles the display of a large number of points
• Heat maps — display a large number of points as a heat map
• IconGenerator — display text on your Markers
• Poly decoding and encoding — compact encoding for paths, interoperability with Maps API web services
• Spherical geometry — for example: computeDistance, computeHeading, computeArea
• KML — displays KML data
• GeoJSON — displays and styles GeoJSON data

3. Polyline Libraries

DrawRouteMaps

If you want to add route maps feature in your apps you can use DrawRouteMaps to make you work more easier. This is lib will help you to draw route maps between two point LatLng.

trail-android

Simple, smooth animation for route / polylines on google maps using projections. (WIP)

Google-Directions-Android

This project allows you to calculate the direction between two locations and display the route on a Google Map using the Google Directions API.

A map demo app for quick start with maps

In your .gradle change MinSDK, for example:

• build.gradle (Module: app)
  • before: minSdkVersion 9
  • after: minSdkVersion 14

etc.

Has your problem been resolved? What is your target SDK? Try adding android;maxSDKVersion="21" to <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

This will let Git authenticate on HTTPS using .netrc:

• The file should be named _netrc and located in c:\Users\<username>.
• You will need to set an environment variable called HOME=%USERPROFILE% (set system-wide environment variables using the System option in the control panel. Depending on the version of Windows, you may need to select "Advanced Options".).
• The password stored in the _netrc file cannot contain spaces (quoting the password will not work).

I use Windows 10 Bash shell aka Linux Subsystem aka Ubuntu in Windows 10 as guided here

In order to encode + value using JavaScript, you can use encodeURIComponent function.

Example:

var url = "+11";
var encoded_url = encodeURIComponent(url);
console.log(encoded_url)

The right way is to use SwingFXUtils.toFXImage(bufferedImage,null) to convert a BufferedImage to a JavaFX Image instance and SwingFXUtils.fromFXImage(image,null) for the inverse operation.

Optionally the second parameter can be a WritableImage to avoid further object allocation.

Mustache pros:

• Very popular choice with a large, active community.
• Server side support in many languages, including Java.
• Logic-less templates do a great job of forcing you to separate presentation from logic.
• Clean syntax leads to templates that are easy to build, read, and maintain.

Mustache cons:

• A little too logic-less: basic tasks (e.g. label alternate rows with different CSS classes) are difficult.
• View logic is often pushed back to the server or implemented as a "lambda" (callable function).
• For lambdas to work on client and server, you must write them in JavaScript.

Handlebars pros:

• Logic-less templates do a great job of forcing you to separate presentation from logic.
• Clean syntax leads to templates that are easy to build, read, and maintain.
• Compiled rather than interpreted templates.
• Better support for paths than mustache (ie, reaching deep into a context object).
• Better support for global helpers than mustache.

Handlebars cons:

• Requires server-side JavaScript to render on the server.

Source: The client-side templating throwdown: mustache, handlebars, dust.js, and more

ACID is a set of properties that you would like to apply when modifying a database.

• Atomicity
• Consistency
• Isolation
• Durability

A transaction is a set of related changes which is used to achieve some of the ACID properties. Transactions are tools to achieve the ACID properties.

Atomicity means that you can guarantee that all of a transaction happens, or none of it does; you can do complex operations as one single unit, all or nothing, and a crash, power failure, error, or anything else won't allow you to be in a state in which only some of the related changes have happened.

Consistency means that you guarantee that your data will be consistent; none of the constraints you have on related data will ever be violated.

Isolation means that one transaction cannot read data from another transaction that is not yet completed. If two transactions are executing concurrently, each one will see the world as if they were executing sequentially, and if one needs to read data that is written by another, it will have to wait until the other is finished.

Durability means that once a transaction is complete, it is guaranteed that all of the changes have been recorded to a durable medium (such as a hard disk), and the fact that the transaction has been completed is likewise recorded.

So, transactions are a mechanism for guaranteeing these properties; they are a way of grouping related actions together such that as a whole, a group of operations can be atomic, produce consistent results, be isolated from other operations, and be durably recorded.

Instead of writing the code from the scratch you can use jquery plug in. Such plug in can provide many configuration option as well.

Here is the one I most liked.

http://www.zurb.com/playground/orbit-jquery-image-slider

Loads of answers here, but haven't seen the one I use:

input[type="text"]:read-only { color: blue; }

Note the dash in the pseudo selector. If the input is readonly="false" it'll catch that too since this selector catches the presence of readonly regardless of the value. Technically false is invalid according to specs, but the internet is not a perfect world. If you need to cover that case, you can do this:

input[type="text"]:read-only:not([read-only="false"]) { color: blue; }

textarea works the same way:

textarea:read-only:not([read-only="false"]) { color: blue; }

Keep in mind that html now supports not only type="text", but a slew of other textual types such a number, tel, email, date, time, url, etc. Each would need to be added to the selector.

I use a simple/minimal solution, one line, cross browser, and works with legacy browsers as well:

/\bmyClass/.test(document.body.className) // notice the \b command for whole word 'myClass'

This method is great because does not require polyfills and if you use them for classList it's much better in terms of performance. At least for me.

Update: I made a tiny polyfill that's an all round solution I use now:

function hasClass(element,testClass){
  if ('classList' in element) { return element.classList.contains(testClass);
} else { return new Regexp(testClass).exec(element.className); } // this is better

//} else { return el.className.indexOf(testClass) != -1; } // this is faster but requires indexOf() polyfill
  return false;
}

For the other class manipulation, see the complete file here.

Try setting the initial value when you instantiate the form:

form = MyForm(initial={'max_number': '3'})

The accepted answer does not show 0 in integer place on giving input like 0.299. It shows .3 in WPF UI. So my suggestion to use following string format

<TextBox Text="{Binding Value,  StringFormat={}{0:#,0.0}}" 

I'm interpreting your question to be about getting row numbers.

• You can try as.numeric(rownames(df)) if you haven't set the rownames. Otherwise use a sequence of 1:nrow(df).
• The which() function converts a TRUE/FALSE row index into row numbers.

First get the value from edit text in a String variable

String value = edttxt.getText().toString();

Then set that value to textView

txtview.setText(value);

Where edttxt refers to edit text field in XML file and txtview refers to textfield in XML file to show the value

Based on the link provided by @better_use_mkstemp, here's a fiddle where nested iframe resizes to fill parent div: http://jsfiddle.net/orlenko/HNyJS/

Html:

<div id="content">
    <iframe src="http://www.microsoft.com" name="frame2" id="frame2" frameborder="0" marginwidth="0" marginheight="0" scrolling="auto" onload="" allowtransparency="false"></iframe>
</div>
<div id="block"></div>
<div id="header"></div>
<div id="footer"></div>

Relevant parts of CSS:

div#content {
    position: fixed;
    top: 80px;
    left: 40px;
    bottom: 25px;
    min-width: 200px;
    width: 40%;
    background: black;
}

div#content iframe {
    position: absolute;
    top: 0;
    bottom: 0;
    left: 0;
    right: 0;
    height: 100%;
    width: 100%;
}

You can create a custom layout and apply it to the actionBar.

To do so, follow those 2 simple steps:

1. Java Code

   getSupportActionBar().setDisplayOptions(ActionBar.DISPLAY_SHOW_CUSTOM);
   getSupportActionBar().setCustomView(R.layout.actionbar);
   

Where R.layout.actionbar is the following layout.

2. XML

   <?xml version="1.0" encoding="utf-8"?>
   <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
       android:layout_width="match_parent"
       android:layout_height="wrap_content"
       android:layout_gravity="center"
       android:orientation="vertical">
   
   <TextView
       android:layout_width="wrap_content"
       android:layout_height="wrap_content"
       android:layout_gravity="center"
       android:id="@+id/action_bar_title"
       android:text="YOUR ACTIVITY TITLE"
       android:textColor="#ffffff"
       android:textSize="24sp" />
   </LinearLayout>
   

It can be as complex as you want. Try it out!

EDIT:

To set the background you can use the property android:background in the container layout (LinearLayout in that case). You may need to set the layout height android:layout_height to match_parent instead of wrap_content.

Moreover, you can also add a LOGO / ICON to it. To do so, simply add an ImageView inside your layout, and set layout orientation property android:orientation to horizontal (or simply use a RelativeLayout and manage it by yourself).

To change the title of above custom action bar dynamically, do this:

TextView title=(TextView)findViewById(getResources().getIdentifier("action_bar_title", "id", getPackageName()));
title.setText("Your Text Here");

You can get first element via index selector:

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

ASP.NET MVC offers us three options ViewData, ViewBag, and TempData for passing data from controller to view and in next request. ViewData and ViewBag are almost similar and TempData performs additional responsibility. Lets discuss or get key points on those three objects:

Similarities between ViewBag & ViewData :

• Helps to maintain data when you move from controller to view.
• Used to pass data from controller to corresponding view.
• Short life means value becomes null when redirection occurs. This is because their goal is to provide a way to communicate between controllers and views. It’s a communication mechanism within the server call.

Difference between ViewBag & ViewData:

• ViewData is a dictionary of objects that is derived from ViewDataDictionary class and accessible using strings as keys.
• ViewBag is a dynamic property that takes advantage of the new dynamic features in C# 4.0.
• ViewData requires typecasting for complex data type and check for null values to avoid error.
• ViewBag doesn’t require typecasting for complex data type.

ViewBag & ViewData Example:

public ActionResult Index()
{
    ViewBag.Name = "Monjurul Habib";
    return View();
}


public ActionResult Index()
{
    ViewData["Name"] = "Monjurul Habib";
    return View();
} 

In View:

@ViewBag.Name 
@ViewData["Name"] 

TempData:

TempData is also a dictionary derived from TempDataDictionary class and stored in short lives session and it is a string key and object value. The difference is that the life cycle of the object. TempData keep the information for the time of an HTTP Request. This mean only from one page to another. This also work with a 302/303 redirection because it’s in the same HTTP Request. Helps to maintain data when you move from one controller to other controller or from one action to other action. In other words when you redirect, “TempData” helps to maintain data between those redirects. It internally uses session variables. Temp data use during the current and subsequent request only means it is use when you are sure that next request will be redirecting to next view. It requires typecasting for complex data type and check for null values to avoid error. Generally used to store only one time messages like error messages, validation messages.

public ActionResult Index()
{
  var model = new Review()
            {
                Body = "Start",
                Rating=5
            };
    TempData["ModelName"] = model;
    return RedirectToAction("About");
}

public ActionResult About()
{
    var model= TempData["ModelName"];
    return View(model);
}

The last mechanism is the Session which work like the ViewData, like a Dictionary that take a string for key and object for value. This one is stored into the client Cookie and can be used for a much more long time. It also need more verification to never have any confidential information. Regarding ViewData or ViewBag you should use it intelligently for application performance. Because each action goes through the whole life cycle of regular asp.net mvc request. You can use ViewData/ViewBag in your child action but be careful that you are not using it to populate the unrelated data which can pollute your controller.

I actually had a similar issue, where we had to many trusted root certificates. Our fresh installed webserver had over a hunded. Our root started with the letter Z so it ended up at the end of the list.

The problem was that the IIS sent only the first twenty-something trusted roots to the client and truncated the rest, including ours. It was a few years ago, can't remember the name of the tool... it was part of the IIS admin suite, but Fiddler should do as well. After realizing the error, we removed a lot trusted roots that we don't need. This was done trial and error, so be careful what you delete.

After the cleanup everything worked like a charm.

Nobody mentioned the limit on the size of the stack frame.

There are two places memory can be allocated:

• On the heap (dynamically allocated memory).
  The size limit here is a combination of available hardware and the OS's ability to simulate space by using other devices to temporarily store unused data (i.e. move pages to hard disk).
• On the stack (Locally declared variables).
  The size limit here is compiler defined (with possible hardware limits). If you read the compiler documentation you can often tweak this size.

Thus if you allocate an array dynamically (the limit is large and described in detail by other posts.

int* a1 = new int[SIZE];  // SIZE limited only by OS/Hardware

Alternatively if the array is allocated on the stack then you are limited by the size of the stack frame. N.B. vectors and other containers have a small presence in the stack but usually the bulk of the data will be on the heap.

int a2[SIZE]; // SIZE limited by COMPILER to the size of the stack frame

I met the same error. And after a lot search, I finally found this one: Angular2 application install & run via package.json. Then I tried to replace

"scripts": { "start": "tsc && concurrently \"npm run tsc:w\" \"npm run lite\" ", "lite": "lite-server", "postinstall": "typings install", "tsc": "tsc", "tsc:w": "tsc -w", "typings": "typings" }, to

"scripts": { "start": "concurrently \"npm run tsc:w\" \"npm run lite\" ", "lite": "lite-server", "postinstall": "typings install", "tsc": "tsc", "tsc:w": "tsc -w", "typings": "typings" },

Hope it helps who get the same error.

PS: My error is not the same as Tomasz, which is my npm version is 3.7.3 and node version is 5.9.1.

You can try of the following type :

#!/bin/bash
 declare -a arr

 i=0
 j=0

  for dir in $(find /home/rmajeti/programs -type d)
   do
        arr[i]=$dir
        i=$((i+1))
   done


  while [ $j -lt $i ]
  do
        echo ${arr[$j]}
        j=$((j+1))
  done

Often it is easier to parse without VBA, when you don't want to enable macros. This can be done with the replace function. Enter your start and end nodes into cells B1 and C1.

Cell A1: {your XML here}
Cell B1: <X>
Cell C1: </X>
Cell D1: =REPLACE(A1,1,FIND(A2,A1)+LEN(A2)-1,"")
Cell E1: =REPLACE(A4,FIND(A3,A4),LEN(A4)-FIND(A3,A4)+1,"")

And the result line E1 will have your parsed value:

Cell A1: {your XML here}
Cell B1: <X>
Cell C1: </X>
Cell D1: 24.365<X><Y>78.68</Y></PointN>
Cell E1: 24.365

What you are trying to achieve should be done in the web browser because javascript simply doesn't work with html email design. The various email clients that are out there e.g. gmail, outlook, yahoo strip scripts put of the code for security reasons.

It is best to just use HTML and CSS to style your emails. Maybe you could have a call to action (cta) in your html email that sends the user to a web page with your expanding and collapsing content feature.

You create an empty project in gitlab then on your local terminal follow one of these:

Push an existing folder

cd existing_folder
git init
git remote add origin [email protected]:GITLABUSERNAME/YOURGITPROJECTNAME.git
git add .
git commit -m "Initial commit"
git push -u origin master

Push an existing Git repository

cd existing_repo
git remote rename origin old-origin
git remote add origin [email protected]:GITLABUSERNAME/YOURGITPROJECTNAME.git

I don't think there is a way to do this. I submitted a feature request. If there is a way, the developers at Google will surly point it out and I will edit my answer. If not, we will have to wait and watch. (you can star the issue to vote for it)

Comment 1 by Chrome project member: In 10.0.620.0, the Styles panel shows the :hover styles for the selected element but not :active.

(as of this post) Current Stable channel version is 8.0.552.224.

You can replace your Stable channel installation of Google Chrome with the Beta channel or the Dev channel (See Early Access Release Channels).

You can also install a secondary installation of chrome that is even more up to date than the Dev channel.

... The Canary build is updated even more frequently than the Dev channel and is not tested before being released. Because the Canary build may at times be unusable, it cannot be set as your default browser and may be installed in addition to any of the above channels of Google Chrome. ...

The reduce function also works

import operator
h=['a','b','c','d']
reduce(operator.add, h)
'abcd'

The error TypeError: 'numpy.ndarray' object is not callable means that you tried to call a numpy array as a function. We can reproduce the error like so in the repl:

In [16]: import numpy as np

In [17]: np.array([1,2,3])()
---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)
/home/user/<ipython-input-17-1abf8f3c8162> in <module>()
----> 1 np.array([1,2,3])()

TypeError: 'numpy.ndarray' object is not callable

If we are to assume that the error is indeed coming from the snippet of code that you posted (something that you should check,) then you must have reassigned either pd.rolling_mean or pd.rolling_std to a numpy array earlier in your code.

What I mean is something like this:

In [1]: import numpy as np

In [2]: import pandas as pd

In [3]: pd.rolling_mean(np.array([1,2,3]), 20, min_periods=5) # Works
Out[3]: array([ nan,  nan,  nan])

In [4]: pd.rolling_mean = np.array([1,2,3])

In [5]: pd.rolling_mean(np.array([1,2,3]), 20, min_periods=5) # Doesn't work anymore...
---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)
/home/user/<ipython-input-5-f528129299b9> in <module>()
----> 1 pd.rolling_mean(np.array([1,2,3]), 20, min_periods=5) # Doesn't work anymore...

TypeError: 'numpy.ndarray' object is not callable

So, basically you need to search the rest of your codebase for pd.rolling_mean = ... and/or pd.rolling_std = ... to see where you may have overwritten them.

I had the same problem and I've already tried everything and nothing seemed to work until I just changed the 'host' value in config.php to:

 'host' => env('smtp.mailtrap.io'),

When I changed that it worked nicely, somehow it was using the default host " smtp.mailtrap.org" and ignoring the .env variable I was setting.

After making some test I realize that if I placed the env variable in this order it would worked as it shoulded:

MAIL_HOST=smtp.mailtrap.io

?MAIL_DRIVER=smtp

?MAIL_PORT=2525?

MAIL_USERNAME=xxxx

?MAIL_PASSWORD=xxx

?MAIL_ENCRYPTION=null

I can see only 1 things happening here: You did't set properly dependences to thelibrary.lib in your project meaning that thelibrary.lib is built in the wrong order (Or in the same time if you have more then 1 CPU build configuration, which can also explain randomness of the error). ( You can change the project dependences in: Menu->Project->Project Dependencies )

I had the same problem while installing scipy-0.17.0-cp35-none-win_amd64.whl and my Python version is 3.5. It returned the same error message:

 scipy-0.17.0-cp35-none-win_amd64.whl is not supported wheel on this platform.

I realized that amd64 is not about my Windows, but about the Python version. Actually I am using a 32 bit Python on a 64 bit Windows. Installing the following file solved the issue:

scipy-0.17.0-cp35-none-win32.whl

I prefer a non blocking approach:

            Dim aw1=GenerateCodeAsync().GetAwaiter()
            While Not aw1.IsCompleted
                Application.DoEvents()
            End While

For the Base64 code like:

"data:image/jpg;base64,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"

Use Swift5.0 code like:

func imageFromBase64(_ base64: String) -> UIImage? {
    if let url = URL(string: base64) {
        if let data = try? Data(contentsOf: url) {
            return UIImage(data: data)
        }
    }
    return nil
}

You can also use the root shortcut like so

  <template>
   <div class="container">
    <h1>Recipes</h1>
      <img src="@/assets/burger.jpg" />
   </div>
  </template>

Although this was Nuxt, it should be same with Vue CLI.

Usually I handle my operations within a transaction. As I've experienced, it is not enough to set the context command timeout, but the transaction needs a constructor with a timeout parameter. I had to set both time out values for it to work properly.

int? prevto = uow.Context.Database.CommandTimeout;
uow.Context.Database.CommandTimeout = 900;
using (TransactionScope scope = new TransactionScope(TransactionScopeOption.Required, TimeSpan.FromSeconds(900))) {
...
}

At the end of the function I set back the command timeout to the previous value in prevto.

Using EF6

I've created the visualization which should help to understand the idea. Semaphore controls access to a common resource in a multithreading environment.

ExecutorService executor = Executors.newFixedThreadPool(7);

Semaphore semaphore = new Semaphore(4);

Runnable longRunningTask = () -> {
    boolean permit = false;
    try {
        permit = semaphore.tryAcquire(1, TimeUnit.SECONDS);
        if (permit) {
            System.out.println("Semaphore acquired");
            Thread.sleep(5);
        } else {
            System.out.println("Could not acquire semaphore");
        }
    } catch (InterruptedException e) {
        throw new IllegalStateException(e);
    } finally {
        if (permit) {
            semaphore.release();
        }
    }
};

// execute tasks
for (int j = 0; j < 10; j++) {
    executor.submit(longRunningTask);
}
executor.shutdown();

Output

Semaphore acquired
Semaphore acquired
Semaphore acquired
Semaphore acquired
Could not acquire semaphore
Could not acquire semaphore
Could not acquire semaphore

Sample code from the article

Here it is a simpler way to achieve that:

1. Set the three elements' container (#outer) display: table
2. And set the elements themselves (#inner) display: table-cell
3. Remove the floating.
4. Success.

#outer{
    display: table;
}
#inner {
    display: table-cell;
    float: none;
}

I like matching the editor dark scheme to IPython dark scheme. As for IPython, go to

Tools > Preferences > IPython cosole > display tab

and check Dark background.

Restart the kernel. Then look at the colors you get, say, when you import. My spyder2 (python 2.7) uses Anaconda's ipython 5.3.0 and import is pink, the best matching scheme for the editor is Monokai, you choose this in

Tools > Preferences > Syntax coloring

My spyder3, when choosing dark IPython (2.4.1) background prints colors a bit different than Monokai, but if you go to

Tools > Preferences > Syntax coloring  

you go to Monokai tab and tweak the colors a bit. I had to change builtin from lilac to cyan

It's a common interview question asked by Facebook etc. I don't think it's a good idea to use the Newton's method in an interview. What if the interviewer ask you the mechanism of the Newton's method when you don't really understand it?

I provided a binary search based solution in Java which I believe everyone can understand.

public int sqrt(int x) {

    if(x < 0) return -1;
    if(x == 0 || x == 1) return x;

    int lowerbound = 1;
    int upperbound = x;
    int root = lowerbound + (upperbound - lowerbound)/2;

    while(root > x/root || root+1 <= x/(root+1)){
        if(root > x/root){
            upperbound = root;
        } else {
            lowerbound = root;
        }
        root = lowerbound + (upperbound - lowerbound)/2;
    }
    return root;
}

You can test my code here: leetcode: sqrt(x)

I ran into the same problem while installing a package via npm.

After creating the npm folder manually in C:\Users\UserName\AppData\Roaming\ that particular error was gone, but it gave similar multiple errors as it tried to create additional directories in the npm folder and failed. The issue was resolved after running the command prompt as an administrator.

mysqli can run multiple queries separated by a ;

you could read in the whole file and run it all at once using mysqli_multi_query()

But, I'll be the first to say that this isn't the most elegant solution.

std::find().

On a current python version you have to use parenthesis, like so :

print ("If there was a birth every 7 seconds", X)

Another polyfill for element.classList is here. I found it via MDN.

I include that script and use element.classList.add("first","second","third") as it's intended.

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

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

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

It's easy just add the name which you want to use in quotes before adding vector

a_matrix <- cbind(b_matrix,'Name-Change'= c_vector)

Declare your menu field.

private Menu menu;

Following is onCreateOptionsMenu() method

public boolean onCreateOptionsMenu(Menu menu) {
this.menu = menu;
    try {
        getMenuInflater().inflate(R.menu.menu_main,menu);
    } catch (Exception e) {
        e.printStackTrace();
        Log.i(TAG, "onCreateOptionsMenu: error: "+e.getMessage());
    }
    return super.onCreateOptionsMenu(menu);
}

Following will be your name setter activity. Either through a button click or through conditional code

public void setMenuName(){
menu.findItem(R.id.menuItemId).setTitle(/*Set your desired menu title here*/);
}

This worked for me.

nohup blah &

Substitute your process name for blah!

It's a separate statement.

It's also not possible to insert into a table and select from it and build an index in the same statement either.

The BOL entry contains the information you need:

CLUSTERED | NONCLUSTERED
Indicate that a clustered or a nonclustered index is created for the PRIMARY KEY or UNIQUE constraint. PRIMARY KEY constraints default to CLUSTERED, and UNIQUE constraints default to NONCLUSTERED.

In a CREATE TABLE statement, CLUSTERED can be specified for only one constraint. If CLUSTERED is specified for a UNIQUE constraint and a PRIMARY KEY constraint is also specified, the PRIMARY KEY defaults to NONCLUSTERED.

You can create an index on a PK field, but not a non-clustered index on a non-pk non-unique-constrained field.

A NCL index is not relevant to the structure of the table, and is not a constraint on the data inside the table. It's a separate entity that supports the table but is not integral to it's functionality or design.

That's why it's a separate statement. The NCL index is irrelevant to the table from a design perspective (query optimization notwithstanding).

This is actually on the main page of nltk.org:

>>> import nltk
>>> sentence = """At eight o'clock on Thursday morning
... Arthur didn't feel very good."""
>>> tokens = nltk.word_tokenize(sentence)
>>> tokens
['At', 'eight', "o'clock", 'on', 'Thursday', 'morning',
'Arthur', 'did', "n't", 'feel', 'very', 'good', '.']

This solved my problem, from preventign that an event gets fired by a children:

doSmth(){_x000D_
  // what ever_x000D_
}

        <div (click)="doSmth()">_x000D_
            <div (click)="$event.stopPropagation()">_x000D_
                <my-component></my-component>_x000D_
            </div>_x000D_
        </div>

Git log but you need to prefix the path with --

Eg:

Following Steps are much enough to back button:

Step 1: This code should be in Manifest.xml

<activity android:name=".activity.ChildActivity"
        android:parentActivityName=".activity.ParentActivity"
        android:screenOrientation="portrait">
        <meta-data
            android:name="android.support.PARENT_ACTIVITY"
            android:value=".activity.ParentActivity" /></activity>

Step 2: You won't give

finish();

in your Parent Activity while starting Child Activity.

Step 3: If you need to come back to Parent Activity from Child Activity, Then you just give this code for Child Activity.

startActivity(new Intent(ParentActivity.this, ChildActivity.class));

Wanting to initalize an array of fixed size is a perfectly acceptable thing to do in any programming language; it isn't like the programmer wants to put a break statement in a while(true) loop. Believe me, especially if the elements are just going to be overwritten and not merely added/subtracted, like is the case of many dynamic programming algorithms, you don't want to mess around with append statements and checking if the element hasn't been initialized yet on the fly (that's a lot of code gents).

object = [0 for x in range(1000)]

This will work for what the programmer is trying to achieve.

Because you can't easily union a function definition and another data type, I find having these types around useful to strongly type them. Based on Drew's answer.

type Func<TArgs extends any[], TResult> = (...args: TArgs) => TResult; 
//Syntax sugar
type Action<TArgs extends any[]> = Func<TArgs, undefined>; 

Now you can strongly type every parameter and the return type! Here's an example with more parameters than what is above.

save(callback: Func<[string, Object, boolean], number>): number
{
    let str = "";
    let obj = {};
    let bool = true;
    let result: number = callback(str, obj, bool);
    return result;
}

Now you can write a union type, like an object or a function returning an object, without creating a brand new type that may need to be exported or consumed.

//THIS DOESN'T WORK
let myVar1: boolean | (parameters: object) => boolean;

//This works, but requires a type be defined each time
type myBoolFunc = (parameters: object) => boolean;
let myVar1: boolean | myBoolFunc;

//This works, with a generic type that can be used anywhere
let myVar2: boolean | Func<[object], boolean>;

An Euler path is a path that passes through every edge exactly once. If it ends at the initial vertex then it is an Euler cycle.

A Hamiltonian path is a path that passes through every vertex exactly once (NOT every edge). If it ends at the initial vertex then it is a Hamiltonian cycle.

In an Euler path you might pass through a vertex more than once.

In a Hamiltonian path you may not pass through all edges.

In actionPerformed(ActionEvent e) you call encrypt(), which is declared to throw Exception. However, actionPerformed neither catches this Exception (with try/catch around the call to encrypt()) nor declares that it throws Exception itself.

Your encrypt method, however, does not truly throw Exception. It swallows all Exceptions without even as much as logging a complaint. (Bad practice and bad style!)

Also, your encrypt method does the following:

public static byte[] encrypt(String toEncrypt) throws Exception {
  try{
    ....
    return encrypted; // HERE YOU CORRECTLY RETURN A VALUE
  } catch(Exception e) {
  }
  // YOU DO NOT RETURN ANYTHING HERE
}

That is, if you do catch any Exception, you discard it silently and then fall off the bottom of your encrypt method without actually returning anything. This won't compile (as you see), because a method that is declared to return a value must either return a value or throw an Exception for every single possible code path.

I would have a directory somewhere called scripts under the WWW folder so that it's not reachable from the web but is reachable by PHP.

e.g. /var/www/scripts/testscript

Make sure the user/group for your testscript is the same as your webfiles. For instance if your client.php is owned by apache:apache, change the bash script to the same user/group using chown. You can find out what your client.php and web files are owned by doing ls -al.

Then run

<?php
      $message=shell_exec("/var/www/scripts/testscript 2>&1");
      print_r($message);
    ?>  

EDIT:

If you really want to run a file as root from a webserver you can try this binary wrapper below. Check out this solution for the same thing you want to do.

Execute root commands via PHP

In case you need this within an input where the user can type 0 and 0x too but not a hex number without the 0x prefix:

^0?[xX]?[0-9a-fA-F]*$

The Network pending state on time, means your request is in progressing state. As soon as it responds the time will be updated with total elapsed time.

This picture shows the network call is in processing state(Pending)

This picture shows the time taken in processing by network call.

Executing a click via JavaScript has some behaviors of which you should be aware. If for example, the code bound to the onclick event of your element invokes window.alert(), you may find your Selenium code hanging, depending on the implementation of the browser driver. That said, you can use the JavascriptExecutor class to do this. My solution differs from others proposed, however, in that you can still use the WebDriver methods for locating the elements.

// Assume driver is a valid WebDriver instance that
// has been properly instantiated elsewhere.
WebElement element = driver.findElement(By.id("gbqfd"));
JavascriptExecutor executor = (JavascriptExecutor)driver;
executor.executeScript("arguments[0].click();", element);

You should also note that you might be better off using the click() method of the WebElement interface, but disabling native events before instantiating your driver. This would accomplish the same goal (with the same potential limitations), but not force you to write and maintain your own JavaScript.

This is a simple way to select an option from a dropdownlist based on a string val

private void SetDDLs(DropDownList d,string val)
    {
        ListItem li;
        for (int i = 0; i < d.Items.Count; i++)
        {
            li = d.Items[i];
            if (li.Value == val)
            {
                d.SelectedIndex = i;
                break;
            }
        }
    }

Assuming you want an actual SQL Server MERGE statement:

MERGE INTO dbo.energydata WITH (HOLDLOCK) AS target
USING dbo.temp_energydata AS source
    ON target.webmeterID = source.webmeterID
    AND target.DateTime = source.DateTime
WHEN MATCHED THEN 
    UPDATE SET target.kWh = source.kWh
WHEN NOT MATCHED BY TARGET THEN
    INSERT (webmeterID, DateTime, kWh)
    VALUES (source.webmeterID, source.DateTime, source.kWh);

If you also want to delete records in the target that aren't in the source:

MERGE INTO dbo.energydata WITH (HOLDLOCK) AS target
USING dbo.temp_energydata AS source
    ON target.webmeterID = source.webmeterID
    AND target.DateTime = source.DateTime
WHEN MATCHED THEN 
    UPDATE SET target.kWh = source.kWh
WHEN NOT MATCHED BY TARGET THEN
    INSERT (webmeterID, DateTime, kWh)
    VALUES (source.webmeterID, source.DateTime, source.kWh)
WHEN NOT MATCHED BY SOURCE THEN
    DELETE;

Because this has become a bit more popular, I feel like I should expand this answer a bit with some caveats to be aware of.

First, there are several blogs which report concurrency issues with the MERGE statement in older versions of SQL Server. I do not know if this issue has ever been addressed in later editions. Either way, this can largely be worked around by specifying the HOLDLOCK or SERIALIZABLE lock hint:

MERGE INTO dbo.energydata WITH (HOLDLOCK) AS target
[...]

You can also accomplish the same thing with more restrictive transaction isolation levels.

There are several other known issues with MERGE. (Note that since Microsoft nuked Connect and didn't link issues in the old system to issues in the new system, these older issues are hard to track down. Thanks, Microsoft!) From what I can tell, most of them are not common problems or can be worked around with the same locking hints as above, but I haven't tested them.

As it is, even though I've never had any problems with the MERGE statement myself, I always use the WITH (HOLDLOCK) hint now, and I prefer to use the statement only in the most straightforward of cases.

My case, I fix it by:

Go to Build Phases and check Compile Sources files, check if it has duplicate file, just keep one.

As others have mentioned, Google uses a homegrown solution called BigTable and they've released a few papers describing it out into the real world.

The Apache folks have an implementation of the ideas presented in these papers called HBase. HBase is part of the larger Hadoop project which according to their site "is a software platform that lets one easily write and run applications that process vast amounts of data." Some of the benchmarks are quite impressive. Their site is at http://hadoop.apache.org.

Use this code:

Intent intent=new Intent(context,SecondActivty.class);
startActivity(intent);

Here is a simple generic C++11 function contains which works for both arrays and containers:

using namespace std;

template<class C, typename T>
bool contains(C&& c, T e) { return find(begin(c), end(c), e) != end(c); };

Simple usage contains(arr, el) is somewhat similar to in keyword semantics in Python.

Here is a complete demo:

#include <algorithm>
#include <array>
#include <string>
#include <vector>
#include <iostream>

template<typename C, typename T>
bool contains(C&& c, T e) { 
    return std::find(std::begin(c), std::end(c), e) != std::end(c);
};

template<typename C, typename T>
void check(C&& c, T e) {
    std::cout << e << (contains(c,e) ? "" : " not") <<  " found\n";
}

int main() {
    int a[] = { 10, 15, 20 };
    std::array<int, 3> b { 10, 10, 10 };
    std::vector<int> v { 10, 20, 30 };
    std::string s { "Hello, Stack Overflow" };
    
    check(a, 10);
    check(b, 15);
    check(v, 20);
    check(s, 'Z');

    return 0;
}

Output:

10 found
15 not found
20 found
Z not found

just return true inside your if statement

var myArr = [1,2,3,4];

myArr.forEach(function(elem){
  if (elem === 3) {

      return true;

    // Go to "next" iteration. Or "continue" to next iteration...
  }

  console.log(elem);
});

Simple Solution::

use {nativeQuery=true} in your query.

for example

  @Query(value = "select d.id,d.name,d.breed,d.origin from Dog d",nativeQuery = true)
        
    List<Dog> findALL();

I had a similar issue. You won't be able to ping the VM's from external devices if using NAT setting from within VMware's networking options. I switched to bridged connection so that the guest virtual machine will get it's own IP address and and then I added a second adapter set to NAT for the guest to get to the Internet.

If you're using bash....

#!/bin/bash

pushd $(dirname "${0}") > /dev/null
basedir=$(pwd -L)
# Use "pwd -P" for the path without links. man bash for more info.
popd > /dev/null

echo "${basedir}"

You can use the DataGridViewColumn.Width property to do it:

DataGridViewColumn column = dataGridView.Columns[0];
column.Width = 60;

http://msdn.microsoft.com/en-us/library/system.windows.forms.datagridviewcolumn.width.aspx

Based on your own answer, I'm guessing that your column has data formatted like this:

'DD/MM/YYYY HH:MI:SS'

The actual separators between Day/Month/Year don't matter, nor does anything that comes after the year.

You don't say what version of DB2 you are using or what platform it's running on, so I'm going to assume that it's on Linux, UNIX or Windows.

Almost any recent version of DB2 for Linux/UNIX/Windows (8.2 or later, possibly even older versions), you can do this using the TRANSLATE function:

select 
   date(translate('GHIJ-DE-AB',column_with_date,'ABCDEFGHIJ'))
from
   yourtable

With this solution it doesn't matter what comes after the date in your column.

In DB2 9.7, you can also use the TO_DATE function (similar to Oracle's TO_DATE):

date(to_date(column_with_date,'DD-MM-YYYY HH:MI:SS'))

This requires your data match the formatting string; it's easier to understand when looking at it, but not as flexible as the TRANSLATE option.

vim is a handy editor, you simple type vim filename to open the file, edit, save and close.

emacs is an "operating system" pretend to be an editor, you can eval code to change its behavior, and extend it as you like. A mode to receive/send email on emacs is like an email software on operating system.

When doing simple editing, for example, modify a config file, I use vim.

Otherwise, I never leave emacs.

Calculate row means on a subset of columns:

Create a new data.frame which specifies the first column from DF as an column called ID and calculates the mean of all the other fields on that row, and puts that into column entitled 'Means':

data.frame(ID=DF[,1], Means=rowMeans(DF[,-1]))
  ID    Means
1  A 3.666667
2  B 4.333333
3  C 3.333333
4  D 4.666667
5  E 4.333333

just put #login-box before <h2>Welcome</h2> will be ok.

<div class='container'>
    <div class='hero-unit'>
        <div id='login-box' class='pull-right control-group'>
            <div class='clearfix'>
                <input type='text' placeholder='Username' />
            </div>
            <div class='clearfix'>
                <input type='password' placeholder='Password' />
            </div>
            <button type='button' class='btn btn-primary'>Log in</button>
        </div>
        <h2>Welcome</h2>

        <p>Please log in</p>

    </div>
</div>

There are many ways as as outlined above. You can also do this in onNavigationDrawerSelected()in your DrawerActivity

public void setTitle(final String title){
    ((TextView)findViewById(R.id.toolbar_title)).setText(title);
}

@Override
public void onNavigationDrawerItemSelected(int position) {
    // update the main content by replacing fragments
    fragment = null;
    String title = null;
    switch(position){

    case 0:
        fragment = new HomeFragment();
        title = "Home";
        break;
    case 1:
        fragment = new ProfileFragment();
        title = ("Find Work");
        break;
    ...
    }
    if (fragment != null){

        FragmentManager fragmentManager = getFragmentManager();
        fragmentManager
        .beginTransaction()
        .replace(R.id.container,
                fragment).commit();

        //The key is this line
        if (title != null && findViewById(R.id.toolbar_title)!= null ) setTitle(title);
    }
}

My which pip shows the following path:

$ which pip
/home/kmario23/anaconda3/bin/pip

So, whatever package I install using pip install <package-name> will have to be reflected in the list of packages when the list is exported using:

$ conda list --export > conda_list.txt

But, I don't. So, instead I used the following command as suggested by several others:

# get environment name by
$ conda-env list

# get list of all installed packages by (conda, pip, etc.,)
$ conda-env export -n <my-environment-name> > all_packages.yml
# if you haven't created any specific env, then just use 'root'

Now, I can see all the packages in my all-packages.yml file.

This code snippets might be useful. If you want to sort an Object in my case I want to sort by VolumeName:

public List<Volume> getSortedVolumes() throws SystemException {
    List<Volume> volumes = VolumeLocalServiceUtil.getAllVolumes();
    Collections.sort(volumes, new Comparator<Volume>() {
        public int compare(Volume o1, Volume o2) {
            Volume p1 = (Volume) o1;
            Volume p2 = (Volume) o2;
            return p1.getVolumeName().compareToIgnoreCase(
                    p2.getVolumeName());
        }
    });
    return volumes;
}

This works. I use it in my jsp.

I know it's an old thread, but I just looked into schemas myself and think the following could be another good candidate for schema usage:

In a Datawarehouse, with data coming from different sources, you can use a different schema for each source, and then e.g. control access based on the schemas. Also avoids the possible naming collisions between the various source, as another poster replied above.

With VSCode 1.47+ you can simply use OPT-w for this.

Utilizing built-in functionality to trigger emmet, this is the easiest way:

1. Select your text/html.
2. Option+w
3. In the emmet window opened in the command palette, type in the tag or wrapping code you need.
4. Enter
5. Voila

Calendar date = Calendar.getInstance();
date.set(Calendar.DAY_OF_MONTH, 1);

Try this with your user & pass

keytool -list -v -keystore {path of jks file} -alias {keyname} -storepass {keypassword} -keypass {aliaspassword}

Exe

keytool -list -v -keystore "E:\AndroidStudioProject\ParathaApp\key.jks" -alias key0 -storepass mks@1 -keypass golu@1

Take a look at FileSaver.js. It provides a handy saveAs function which takes care of most browser specific quirks.

You can do this per class or globally, I believe.

For per class, try @JsonSerialize above class declaration.

For a mapper, here's one example:

ObjectMapper mapper = new ObjectMapper();
mapper.configure(SerializationFeature.FAIL_ON_EMPTY_BEANS, false);
// do various things, perhaps:
String someJsonString = mapper.writeValueAsString(someClassInstance);
SomeClass someClassInstance = mapper.readValue(someJsonString, SomeClass.class)

The StackOverflow link below also has an example for a Spring project.

For REST with Jersey, I don't remember off the top off my head, but I believe it's similar.

Couple of links I dug up: (edited 1st link due to Codehaus shutting down).

• https://web.archive.org/web/20150513164332/https://jira.codehaus.org/browse/JACKSON-201
• Jackson serializationConfig

You can convert Date to almost any format using the Snippet I have added below.

Code:

dateFormat(new Date(),"dd/mm/yy h:MM TT")
//"20/06/14 6:49 PM"

Other examples

// Can also be used as a standalone function
dateFormat(new Date(), "dddd, mmmm dS, yyyy, h:MM:ss TT");
// Saturday, June 9th, 2007, 5:46:21 PM

dateFormat(new Date(),"dddd d mmmm yyyy")
//Monday 2 June 2014"

Snippet:

Add following code taken from this link into your code.

var dateFormat = function () {
    var token = /d{1,4}|m{1,4}|yy(?:yy)?|([HhMsTt])\1?|[LloSZ]|"[^"]*"|'[^']*'/g,
        timezone = /\b(?:[PMCEA][SDP]T|(?:Pacific|Mountain|Central|Eastern|Atlantic) (?:Standard|Daylight|Prevailing) Time|(?:GMT|UTC)(?:[-+]\d{4})?)\b/g,
        timezoneClip = /[^-+\dA-Z]/g,
        pad = function (val, len) {
            val = String(val);
            len = len || 2;
            while (val.length < len) val = "0" + val;
            return val;
        };

    // Regexes and supporting functions are cached through closure
    return function (date, mask, utc) {
        var dF = dateFormat;

        // You can't provide utc if you skip other args (use the "UTC:" mask prefix)
        if (arguments.length == 1 && Object.prototype.toString.call(date) == "[object String]" && !/\d/.test(date)) {
            mask = date;
            date = undefined;
        }

        // Passing date through Date applies Date.parse, if necessary
        date = date ? new Date(date) : new Date;
        if (isNaN(date)) throw SyntaxError("invalid date");

        mask = String(dF.masks[mask] || mask || dF.masks["default"]);

        // Allow setting the utc argument via the mask
        if (mask.slice(0, 4) == "UTC:") {
            mask = mask.slice(4);
            utc = true;
        }

        var _ = utc ? "getUTC" : "get",
            d = date[_ + "Date"](),
            D = date[_ + "Day"](),
            m = date[_ + "Month"](),
            y = date[_ + "FullYear"](),
            H = date[_ + "Hours"](),
            M = date[_ + "Minutes"](),
            s = date[_ + "Seconds"](),
            L = date[_ + "Milliseconds"](),
            o = utc ? 0 : date.getTimezoneOffset(),

There are many ways to take input from the users. I personally like using the method gets. When you use gets, it gets the string that you typed, and that includes the ENTER key that you pressed to end your input.

name = gets
"mukesh\n"

You can see this in irb; type this and you will see the \n, which is the “newline” character that the ENTER key produces: Type name = gets you will see somethings like "mukesh\n" You can get rid of pesky newline character using chomp method.

The chomp method gives you back the string, but without the terminating newline. Beautiful chomp method life saviour.

name = gets.chomp
"mukesh"

You can also use terminal to read the input. ARGV is a constant defined in the Object class. It is an instance of the Array class and has access to all the array methods. Since it’s an array, even though it’s a constant, its elements can be modified and cleared with no trouble. By default, Ruby captures all the command line arguments passed to a Ruby program (split by spaces) when the command-line binary is invoked and stores them as strings in the ARGV array.

When written inside your Ruby program, ARGV will take take a command line command that looks like this:

test.rb hi my name is mukesh

and create an array that looks like this:

["hi", "my", "name", "is", "mukesh"]

But, if I want to passed limited input then we can use something like this.

test.rb 12 23

and use those input like this in your program:

a = ARGV[0]
b = ARGV[1]

select * from Header where userID like '%''%'

Hope this helps.

The best way is to store native JavaScript Date objects, which map onto BSON native Date objects.

> db.test.insert({date: ISODate()})
> db.test.insert({date: new Date()})
> db.test.find()
{ "_id" : ObjectId("..."), "date" : ISODate("2014-02-10T10:50:42.389Z") }
{ "_id" : ObjectId("..."), "date" : ISODate("2014-02-10T10:50:57.240Z") }

The native type supports a whole range of useful methods out of the box, which you can use in your map-reduce jobs, for example.

If you need to, you can easily convert Date objects to and from Unix timestamps¹⁾, using the getTime() method and Date(milliseconds) constructor, respectively.

¹⁾ Strictly speaking, the Unix timestamp is measured in seconds. The JavaScript Date object measures in milliseconds since the Unix epoch.

To determine if an argument was passed at all, I use a custom utility object as the default value:

MISSING = object()

The issue here is that ng-repeat creates its own scope, so when you do selected=$index it creates a new a selected property in that scope rather than altering the existing one. To fix this you have two options:

Change the selected property to a non-primitive (ie object or array, which makes javascript look up the prototype chain) then set a value on that:

$scope.selected = {value: 0};

<a ng-click="selected.value = $index">A{{$index}}</a>

See plunker

or

Use the $parent variable to access the correct property. Though less recommended as it increases coupling between scopes

<a ng-click="$parent.selected = $index">A{{$index}}</a>

See plunker

This may not be the same problem that the OP had but in case someone got here with the same mistake I had then this will help them solve their problem. I got the same error as the OP when I used an ObjectMapper from a different dependency as the JsonProperty annotation.

This works:

import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.annotation.JsonProperty;

Does NOT work:

import org.codehaus.jackson.map.ObjectMapper; //org.codehaus.jackson:jackson-mapper-asl:1.8.8
import com.fasterxml.jackson.annotation.JsonProperty; //com.fasterxml.jackson.core:jackson-databind:2.2.3

I was just searching for a solution for this :)

it appears that you can't have OkControlID assign to a control if you want to that control fires an event, just removing this property I got everything working again.

my code (working):

<asp:Panel ID="pnlResetPanelsView" CssClass="modalPopup" runat="server" Style="display:none;">
    <h2>
        Warning</h2>
    <p>
        Do you really want to reset the panels to the default view?</p>

Android 3.2 introduces a new approach to screen sizes,the numbers describing the screen size are all in “dp” units.Mostly we can use

smallest width dp: the smallest width available for application layout in “dp” units; this is the smallest width dp that you will ever encounter in any rotation of the display.

To create one right click on res >>> new >>> Android resource directory

From Available qualifiers window move Smallest Screen Width to Chosen qualifiers

In Screen width window just write the "dp" value starting from you would like Android Studio to use that dimens.

Than change to Project view,right click on your new created resource directory

new >>> Values resource file enter a new file name dimens.xml and you are done.

From my testing Write-Output and [Console]::WriteLine() perform much better than Write-Host.

Depending on how much text you need to write out this may be important.

Below if the result of 5 tests each for Write-Host, Write-Output and [Console]::WriteLine().

In my limited experience, I've found when working with any sort of real world data I need to abandon the cmdlets and go straight for the lower level commands to get any decent performance out of my scripts.

measure-command {$count = 0; while ($count -lt 1000) { Write-Host "hello"; $count++ }}

1312ms
1651ms
1909ms
1685ms
1788ms


measure-command { $count = 0; while ($count -lt 1000) { Write-Output "hello"; $count++ }}

97ms
105ms
94ms
105ms
98ms


measure-command { $count = 0; while ($count -lt 1000) { [console]::WriteLine("hello"); $count++ }}

158ms
105ms
124ms
99ms
95ms

The modulus operator. The remainder when you divide two number.

For Example:

>>> 5 % 2 = 1 # remainder of 5 divided by 2 is 1
>>> 7 % 3 = 1 # remainer of 7 divided by 3 is 1
>>> 3 % 1 = 0 # because 1 divides evenly into 3

For completeness' sake, here's the way to do it with arrow (better dates and times for Python):

sometime = arrow.now()
abitlater = sometime.shift(seconds=3)

This happen after you disable via Control Panel -> network adapters -> right click button on the virtual connection -> disable

To fix that go to Device Manager (Windows-key + x + m on windows 8, Windows-key + x then m on windows 10), then open the network adapters tree , right click button on Microsoft Hosted Network Virtual Adapter and click on enable.

Try now with the command netsh wlan start hostednetwork with admin privileges. It should work.

Note: If you don't see the network adapter with name 'Microsoft Hosted Network Virtual Adapter' try on menu -> view -> show hidden devices in the Device Manager window.

Since the request module that other answers use has been deprecated, may I suggest switching to node-fetch:

const fetch = require("node-fetch")

const url = "https://www.googleapis.com/urlshortener/v1/url"
const payload = { longUrl: "http://www.google.com/" }

const res = await fetch(url, {
  method: "post",
  body: JSON.stringify(payload),
  headers: { "Content-Type": "application/json" },
})

const { id } = await res.json()

You have two choices, depending on your table order

create table aa (sht int)
create table cc (sht int)
create table cd (sht int)
create table ab (sht int)

-- type 1    
select * from cd
inner join cc on cd.sht = cc.sht
LEFT JOIN ab ON ab.sht = cd.sht
LEFT JOIN aa ON aa.sht = cc.sht

-- type 2
select * from cc
inner join cc on cd.sht = cc.sht
LEFT JOIN ab
LEFT JOIN aa
ON aa.sht = ab.sht

Have you seen the FAQ entry What if I'm behind a proxy??

... edit your "servers" configuration file to indicate which proxy to use. The files location depends on your operating system. On Linux or Unix it is located in the directory "~/.subversion". On Windows it is in "%APPDATA%\Subversion". (Try "echo %APPDATA%", note this is a hidden directory.)

For me this involved uncommenting and setting the following lines:

#http-proxy-host=my.proxy
#http-proxy-port=80
#http-proxy-username=[username]
#http-proxy-password=[password]

On command line : nano ~/.subversion/servers

First step is to save all open notebooks. And then think about shutting down your running Jupyter Notebook. You can use this simple command:

$ jupyter notebook stop 
Shutting down server on port 8888 ...

Which also takes the port number as argument and you can shut down the jupyter notebook gracefully.

For eg:

jupyter notebook stop 8889 
Shutting down server on port 8889 ...

Additionally to know your current jupyter instance running, check below command:

shell> jupyter notebook list 
Currently running servers:
http://localhost:8888/?token=ef12021898c435f865ec706de98632 :: /Users/username/jupyter-notebooks [/code]

For some algorithms you need a consistent bias when 'nearest' is a tie.

// round-to-nearest with mid-value bias towards positive infinity
int div_nearest( int n, int d )
   {
   if (d<0) n*=-1, d*=-1;
   return (abs(n)+((d-(n<0?1:0))>>1))/d * ((n<0)?-1:+1);
   }

This works regardless of the sign of the numerator or denominator.

If you want to match the results of round(N/(double)D) (floating-point division and rounding), here are a few variations that all produce the same results:

int div_nearest( int n, int d )
   {
   int r=(n<0?-1:+1)*(abs(d)>>1); // eliminates a division
// int r=((n<0)^(d<0)?-1:+1)*(d/2); // basically the same as @ericbn
// int r=(n*d<0?-1:+1)*(d/2); // small variation from @ericbn
   return (n+r)/d;
   }

Note: The relative speed of (abs(d)>>1) vs. (d/2) is likely to be platform dependent.

If you have configured jenkins on ec2 instance with linux AMI and looking to change the port. Edit the file at

sudo vi /etc/sysconfig/jenkins

Edit

JENKINS_PORT="your port number"

Exit vim

:wq

Restart jenkins

sudo service jenkins restart

Or simply start it, if its not already running

sudo service jenkins start

To verify if your jenkins is running on mentioned port

netstat -lntu | grep "your port number"

try the following:

 myPictureBox.Image = global::mynamespace.Properties.Resources.photo1;

and replace namespace with your project namespace

This works for me using the normal wc -l and sed to strip any char what is not a number.

wc -l big_file.log | sed -E "s/([a-z\-\_\.]|[[:space:]]*)//g"

Symfony 2.1

$response = new Response(json_encode(array('name' => $name)));
$response->headers->set('Content-Type', 'application/json');

return $response;

Symfony 2.2 and higher

You have special JsonResponse class, which serialises array to JSON:

return new JsonResponse(array('name' => $name));

But if your problem is How to serialize entity then you should have a look at JMSSerializerBundle

Assuming that you have it installed, you'll have simply to do

$serializedEntity = $this->container->get('serializer')->serialize($entity, 'json');

return new Response($serializedEntity);

You should also check for similar problems on StackOverflow:

• How to encode Doctrine entities to JSON in Symfony 2.0 AJAX application?
• Symfony 2 Doctrine export to JSON

So here is a simple example of how to use classes: Suppose you are a finance institute. You want your customer's accounts to be managed by a computer. So you need to model those accounts. That is where classes come in. Working with classes is called object oriented programming. With classes you model real world objects in your computer. So, what do we need to model a simple bank account? We need a variable that saves the balance and one that saves the customers name. Additionally, some methods to in- and decrease the balance. That could look like:

class bankaccount():
    def __init__(self, name, money):
        self.name = name
        self.money = money

    def earn_money(self, amount):
        self.money += amount

    def withdraw_money(self, amount):
        self.money -= amount

    def show_balance(self):
        print self.money

Now you have an abstract model of a simple account and its mechanism. The def __init__(self, name, money) is the classes' constructor. It builds up the object in memory. If you now want to open a new account you have to make an instance of your class. In order to do that, you have to call the constructor and pass the needed parameters. In Python a constructor is called by the classes's name:

spidermans_account = bankaccount("SpiderMan", 1000)

If Spiderman wants to buy M.J. a new ring he has to withdraw some money. He would call the withdraw method on his account:

spidermans_account.withdraw_money(100)

If he wants to see the balance he calls:

spidermans_account.show_balance()

The whole thing about classes is to model objects, their attributes and mechanisms. To create an object, instantiate it like in the example. Values are passed to classes with getter and setter methods like `earn_money()´. Those methods access your objects variables. If you want your class to store another object you have to define a variable for that object in the constructor.

Mockito comes with a helper class to save you some reflection boiler plate code:

import org.mockito.internal.util.reflection.Whitebox;

//...

@Mock
private Person mockedPerson;
private Test underTest;

// ...

@Test
public void testMethod() {
    Whitebox.setInternalState(underTest, "person", mockedPerson);
    // ...
}

Update: Unfortunately the mockito team decided to remove the class in Mockito 2. So you are back to writing your own reflection boilerplate code, use another library (e.g. Apache Commons Lang), or simply pilfer the Whitebox class (it is MIT licensed).

Update 2: JUnit 5 comes with its own ReflectionSupport and AnnotationSupport classes that might be useful and save you from pulling in yet another library.

Your font tag is not correct, so it won't work in some browsers. The px unit is used with CSS, not HTML attributes. The font tag should look like this:

<font size="100">

Well, actually it shouldn't be there at all. The font tag is deprecated, you should use CSS to style the content, like you do already with the text-decoration:

<a href="selectTopic?html" style="font-size: 100px; text-decoration: none">HTML 5</a>

To separate the content from the styling, you should of course work towards putting the CSS in a style sheet rather than as inline style attributes. That way you can apply one style to several elements without having to put the same style attribute in all of them.

Example:

<a href="selectTopic?html" class="topic">HTML 5</a>

CSS:

.topic { font-size: 100px; text-decoration: none; }

With SSL the encryption is at the transport level, so it takes place before a request is sent.

So everything in the request is encrypted.

formatDate is the function you can call it and pass the date you want to format to dd/mm/yyyy

It is same as above answers, but is simple in steps

c:\SRC\folder1

c:\SRC\folder2

c:\SRC\folder3

c:\SRC\folder4

to copy all above folders to c:\DST\ except folder1 and folder2.

Step1: create a file c:\list.txt with below content, one folder name per one line

folder1\

folder2\

Step2: Go to command pompt and run as below xcopy c:\SRC*.* c:\DST*.* /EXCLUDE:c:\list.txt

set -o xtrace

or

bash -x myscript.sh

This works with standard /bin/sh as well IIRC (it might be a POSIX thing then)

And remember, there is bashdb (bash Shell Debugger, release 4.0-0.4)

To revert to normal, exit the subshell or

set +o xtrace

Update ListView's contents by below code:

private ListView listViewBuddy;
private BuddyAdapter mBuddyAdapter;
private ArrayList<BuddyModel> buddyList = new ArrayList<BuddyModel>();

onCreate():

listViewBuddy = (ListView)findViewById(R.id.listViewBuddy);
mBuddyAdapter = new BuddyAdapter();
listViewBuddy.setAdapter(mBuddyAdapter);

onDataGet (After webservice call or from local database or otherelse):

mBuddyAdapter.setData(buddyList);
mBuddyAdapter.notifyDataSetChanged();

BaseAdapter:

private class BuddyAdapter extends BaseAdapter { 

    private ArrayList<BuddyModel> mArrayList = new ArrayList<BuddyModel>();
    private LayoutInflater mLayoutInflater= (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    private ViewHolder holder;

    public void setData(ArrayList<BuddyModel> list){
        mArrayList = list;
    }

    @Override
    public int getCount() {
        return mArrayList.size();
    }

    @Override
    public BuddyModel getItem(int position) {
        return mArrayList.get(position);
    }

    @Override
    public long getItemId(int pos) {
        return pos;
    }

    private class ViewHolder {
        private TextView txtBuddyName, txtBuddyBadge;

    }
    @SuppressLint("InflateParams")
    @Override
    public View getView(final int position, View convertView, ViewGroup parent) {
        if (convertView == null) {
            holder = new ViewHolder();
            convertView = mLayoutInflater.inflate(R.layout.row_buddy, null);
            // bind views
            holder.txtBuddyName = (TextView) convertView.findViewById(R.id.txtBuddyName);
            holder.txtBuddyBadge = (TextView) convertView.findViewById(R.id.txtBuddyBadge);

            // set tag
            convertView.setTag(holder);
        } else {
            // get tag
            holder = (ViewHolder) convertView.getTag();
        }

        holder.txtBuddyName.setText(mArrayList.get(position).getFriendId());

        int badge = mArrayList.get(position).getCount();
        if(badge!=0){
            holder.txtBuddyBadge.setVisibility(View.VISIBLE);
            holder.txtBuddyBadge.setText(""+badge);
        }else{
            holder.txtBuddyBadge.setVisibility(View.GONE);
        }   

        return convertView;
    }
}

Whenever you want to Update Listview just call below two lines code:

 mBuddyAdapter.setData(Your_Updated_ArrayList);
 mBuddyAdapter.notifyDataSetChanged();

Done

You can use ssh to forward ports onto somewhere else.

If you have two computers, one you browse from, and one which is free to access websites, and is not logged (ie. you own it and it's sitting at home), then you can set up a tunnel between them to forward http traffic over.

For example, I connect to my home computer from work using ssh, with port forwarding, like this:

ssh -L 22222:<target_website>:80 <home_computer>

Then I can point my browser to

http://localhost:22222/

And this request will be forwarded over ssh. Since the work computer is first contacting the home computer, and then contacting the target website, it will be hard to log.

However, this is all getting into 'how to bypass web proxies' and the like, and I suggest you create a new question asking what exactly you want to do.

Ie. "How do I bypass web proxies to avoid my traffic being logged?"

You are implementing LocationListener in your activity MainActivity. The call for concurrent location updates will therefor be like this:

mLocationClient.requestLocationUpdates(mLocationRequest, this);

Be sure that the LocationListener you're implementing is from the google api, that is import this:

import com.google.android.gms.location.LocationListener;

and not this:

import android.location.LocationListener;

and it should work just fine.

It's also important that the LocationClient really is connected before you do this. I suggest you don't call it in the onCreate or onStart methods, but in onResume. It is all explained quite well in the tutorial for Google Location Api: https://developer.android.com/training/location/index.html

Yes, Since C++11:

struct B2 {
    B2(int = 13, int = 42);
};
struct D2 : B2 {
    using B2::B2;
// The set of inherited constructors is
// 1. B2(const B2&)
// 2. B2(B2&&)
// 3. B2(int = 13, int = 42)
// 4. B2(int = 13)
// 5. B2()

// D2 has the following constructors:
// 1. D2()
// 2. D2(const D2&)
// 3. D2(D2&&)
// 4. D2(int, int) <- inherited
// 5. D2(int) <- inherited
};

For additional information see http://en.cppreference.com/w/cpp/language/using_declaration

Thinking about it in general, I would strongly consider hiding coordinate system behind well-designed abstraction. Quoting Uncle Bob and his book:

class Point(object)
    def setCartesian(self, x, y)
    def setPolar(self, rho, theta)
    def getX(self)
    def getY(self)
    def getRho(self)
    def setTheta(self)

With interface like that any user of Point class may choose convenient representation, no explicit conversions will be performed. All this ugly sines, cosines etc. will be hidden in one place. Point class. Only place where you should care which representation is used in computer memory.

Just in addition to @David Brown´s answer, if you want to block an IP, you must first allow all then block the IPs as such:

    <RequireAll>
      Require all granted
      Require not ip 10.0.0.0/255.0.0.0
      Require not ip 172.16.0.0/12
      Require not ip 192.168
    </RequireAll>

First line allows all
Second line blocks from 10.0.0.0 to 10.255.255.255
Third line blocks from 172.16.0.0 to 172.31.255.255
Fourth line blocks from 192.168.0.0 to 192.168.255.255

You may use any of the notations mentioned above to suit you CIDR needs.

The token has to be placed in an Authorization header according to the following format:

    """
    req=urllib2.Request("https://xforce-api.mybluemix.net/auth/anonymousToken")
    response=urllib2.urlopen(req)
    html=response.read()
    json_obj=json.loads(html)
    token_string=json_obj["token"].encode("ascii","ignore")
    return token_string

def get_response_json_object(url, auth_token):
    """
    returns json object with info
    """
    auth_token=get_auth_token()

    response=urllib2.urlopen(req)
    html=response.read()

The simple way to solve the problem is to use ComparisonChain from Guava http://docs.guava-libraries.googlecode.com/git/javadoc/com/google/common/collect/ComparisonChain.html

private static Comparator<String> stringAlphabeticalComparator = new Comparator<String>() {
        public int compare(String str1, String str2) {
            return ComparisonChain.start().
                                compare(str1,str2, String.CASE_INSENSITIVE_ORDER).
                                compare(str1,str2).
                                result();
         }
 };
Collections.sort(list, stringAlphabeticalComparator);

The first comparator from the chain will sort strings according to the case insensitive order, and the second comparator will sort strings according to the case insensitive order. As excepted strings appear in the result according to the alphabetical order:

"AA","Aa","aa","Development","development"

You have to set the 'float mode' to fixed.

float num = 15.839;

// this will output 15.84
std::cout << std::fixed << "num = " << std::setprecision(2) << num << std::endl;

Exercise 16 from Zed Shaw's book? You can use escape characters as follows:

target.write(paragraph1)

error: package android.support.v4.content does not exist import android.support.v4.content.FileProvider;

using jetify helped to solve .

from jcesarmobile' s post --- >https://github.com/ionic-team/capacitor/pull/2832

Error: "package android.support.* does not exist" This error occurs when some Cordova or Capacitor plugin has old android support dependencies instead of using the new AndroidX equivalent. You should report the issue in the plugin repository so the maintainers can update the plugin to use AndroidX dependencies.

As workaround you can also patch the plugin using jetifier

npm install jetifier

npx jetify

npx cap sync android

You have used regular expression for this format : DD - MM- YYYY

If you need this format DD/MM/YYYY use

var pattern =/^([0-9]{2})\/([0-9]{2})\/([0-9]{4})$/;

Change

JSONObject objects = getArray.getJSONArray(i);

to

JSONObject objects = getArray.getJSONObject(i);

or to

JSONObject objects = getArray.optJSONObject(i);

depending on which JSON-to/from-Java library you're using. (It looks like getJSONObject will work for you.)

Then, to access the string elements in the "objects" JSONObject, get them out by element name.

String a = objects.get("A");

If you need the names of the elements in the JSONObject, you can use the static utility method JSONObject.getNames(JSONObject) to do so.

String[] elementNames = JSONObject.getNames(objects);

"Get the value for the first element and the value for the last element."

If "element" is referring to the component in the array, note that the first component is at index 0, and the last component is at index getArray.length() - 1.

I want to iterate though the objects in the array and get thier component and thier value. In my example the first object has 3 components, the scond has 5 and the third has 4 components. I want iterate though each of them and get thier component name and value.

The following code does exactly that.

import org.json.JSONArray;
import org.json.JSONObject;

public class Foo
{
  public static void main(String[] args) throws Exception
  {
    String jsonInput = "{\"JObjects\":{\"JArray1\":[{\"A\":\"a\",\"B\":\"b\",\"C\":\"c\"},{\"A\":\"a1\",\"B\":\"b2\",\"C\":\"c3\",\"D\":\"d4\",\"E\":\"e5\"},{\"A\":\"aa\",\"B\":\"bb\",\"C\":\"cc\",\"D\":\"dd\"}]}}";

    // "I want to iterate though the objects in the array..."
    JSONObject outerObject = new JSONObject(jsonInput);
    JSONObject innerObject = outerObject.getJSONObject("JObjects");
    JSONArray jsonArray = innerObject.getJSONArray("JArray1");
    for (int i = 0, size = jsonArray.length(); i < size; i++)
    {
      JSONObject objectInArray = jsonArray.getJSONObject(i);

      // "...and get thier component and thier value."
      String[] elementNames = JSONObject.getNames(objectInArray);
      System.out.printf("%d ELEMENTS IN CURRENT OBJECT:\n", elementNames.length);
      for (String elementName : elementNames)
      {
        String value = objectInArray.getString(elementName);
        System.out.printf("name=%s, value=%s\n", elementName, value);
      }
      System.out.println();
    }
  }
}
/*
OUTPUT:
3 ELEMENTS IN CURRENT OBJECT:

tl;dr

cp -R "/src/project 1/App" "/src/project 2"

Explanation:

Using quotes will cater for spaces in the directory names

cp -R "/src/project 1/App" "/src/project 2"

If the App directory is specified in the destination directory:

cp -R "/src/project 1/App" "/src/project 2/App"

and "/src/project 2/App" already exists the result will be "/src/project 2/App/App"

Best not to specify the directory copied in the destination so that the command can be repeated over and over with the expected result.

Inside a bash script:

cp -R "${1}/App" "${2}"

This my extension, this is an example of change image with FadIn and FadOut :

fun ImageView.setImageDrawableWithAnimation(@DrawableRes() resId: Int, duration: Long = 300) {    
    if (drawable != null) {
        animate()
            .alpha(0f)
            .setDuration(duration)
             .withEndAction {
                 setImageResource(resId)
                 animate()
                     .alpha(1f)
                     .setDuration(duration)
             }

    } else if (drawable == null) {
        setAlpha(0f)
        setImageResource(resId)
        animate()
            .alpha(1f)
            .setDuration(duration)
    }
}

I found that along with setting the -p port values, Docker for Windows uses vpnkit and inbound traffic for it was disabled by default on my host machine's firewall. After enabling the inbound TCP rules for vpnkit I was able to access my containers from other machines on the local network.

Try using {} instead of ():

${"file".$i} = file($filelist[$i]);

Before I show you how to reload / refresh model data from the server programmatically? I have to explain for you the concept of Data Binding. This is an extremely powerful concept that will truly revolutionize the way you develop. So may be you have to read about this concept from this link or this seconde link in order to unterstand how AngularjS work.

now I'll show you a sample example that exaplain how can you update your model from server.

HTML Code:

<div ng-controller="PersonListCtrl">
    <ul>
        <li ng-repeat="person in persons">
            Name: {{person.name}}, Age {{person.age}}
        </li>
    </ul>
   <button ng-click="updateData()">Refresh Data</button>
</div>

So our controller named: PersonListCtrl and our Model named: persons. go to your Controller js in order to develop the function named: updateData() that will be invoked when we are need to update and refresh our Model persons.

Javascript Code:

app.controller('adsController', function($log,$scope,...){

.....

$scope.updateData = function(){
$http.get('/persons').success(function(data) {
       $scope.persons = data;// Update Model-- Line X
     });
}

});

Now I explain for you how it work: when user click on button Refresh Data, the server will call to function updateData() and inside this function we will invoke our web service by the function $http.get() and when we have the result from our ws we will affect it to our model (Line X).Dice that affects the results for our model, our View of this list will be changed with new Data.

An easy way to reduce compilation time in larger C++ projects is to make a *.cpp include file that includes all the cpp files in your project and compile that. This reduces the header explosion problem to once. The advantage of this is that compilation errors will still reference the correct file.

For example, assume you have a.cpp, b.cpp and c.cpp.. create a file: everything.cpp:

#include "a.cpp"
#include "b.cpp"
#include "c.cpp"

Then compile the project by just making everything.cpp

You should be able to view all the global environment variables that are available during the build by navigating to https://<your-jenkins>/env-vars.html.

Replace https://<your-jenkins>/ with the URL you use to get to Jenkins webpage (for example, it could be http://localhost:8080/env-vars.html).

One of the environment variables is :

BUILD_ID
    The current build id, such as "2005-08-22_23-59-59" (YYYY-MM-DD_hh-mm-ss)

If you use jenkins editable email notification, you should be able to use ${ENV, var="BUILD_ID"} in the subject line of your email.

Tracemalloc module was integrated as a built-in module starting from Python 3.4, and appearently, it's also available for prior versions of Python as a third-party library (haven't tested it though).

This module is able to output the precise files and lines that allocated the most memory. IMHO, this information is infinitly more valuable than the number of allocated instances for each type (which ends up being a lot of tuples 99% of the time, which is a clue, but barely helps in most cases).

I recommend you use tracemalloc in combination with pyrasite. 9 times out of 10, running the top 10 snippet in a pyrasite-shell will give you enough information and hints to to fix the leak within 10 minutes. Yet, if you're still unable to find the leak cause, pyrasite-shell in combination with the other tools mentioned in this thread will probably give you some more hints too. You should also take a look on all the extra helpers provided by pyrasite (such as the memory viewer).

Use std::vector for this. For example:

std::vector<int> values;
values.resize(n);

The memory will be allocated on the heap, but this holds only a small performance drawback. Furthermore, it is wise not to allocate large datablocks on the stack, as it is rather limited in size.

I also had to deal with this problem, so here my solution. It works great for me.

1. Create class DelegateCommand

    public class DelegateCommand<T> : ICommand
{
    private Predicate<T> _canExecuteMethod;
    private readonly Action<T> _executeMethod;
    public event EventHandler CanExecuteChanged;

    public DelegateCommand(Action<T> executeMethod) : this(executeMethod, null)
    {
    }
    public DelegateCommand(Action<T> executeMethod, Predicate<T> canExecuteMethod)
    {
        this._canExecuteMethod = canExecuteMethod;
        this._executeMethod = executeMethod ?? throw new ArgumentNullException(nameof(executeMethod), "Command is not specified."); 
    }


    public void RaiseCanExecuteChanged()
    {
        if (this.CanExecuteChanged != null)
            CanExecuteChanged(this, null);
    }
    public bool CanExecute(object parameter)
    {
        return _canExecuteMethod == null || _canExecuteMethod((T)parameter) == true;
    }

    public void Execute(object parameter)
    {
        _executeMethod((T)parameter);
    }
}

2. Define your command

        public DelegateCommand<Window> CloseWindowCommand { get; private set; }


    public MyViewModel()//ctor of your viewmodel
    {
        //do something

        CloseWindowCommand = new DelegateCommand<Window>(CloseWindow);


    }
        public void CloseWindow(Window win) // this method is also in your viewmodel
    {
        //do something
        win?.Close();
    }

3. Bind your command in the view

public MyView(Window win) //ctor of your view, window as parameter
    {
        InitializeComponent();
        MyButton.CommandParameter = win;
        MyButton.Command = ((MyViewModel)this.DataContext).CloseWindowCommand;
    }

4. And now the window

  Window win = new Window()
        {
            Title = "My Window",
            Height = 800,
            Width = 800,
            WindowStartupLocation = WindowStartupLocation.CenterScreen,

        };
        win.Content = new MyView(win);
        win.ShowDialog();

so thats it, you can also bind the command in the xaml file and find the window with FindAncestor and bind it to the command parameter.

I recommend Dowser. It is very easy to setup, and you need zero changes to your code. You can view counts of objects of each type through time, view list of live objects, view references to live objects, all from the simple web interface.

# memdebug.py

import cherrypy
import dowser

def start(port):
    cherrypy.tree.mount(dowser.Root())
    cherrypy.config.update({
        'environment': 'embedded',
        'server.socket_port': port
    })
    cherrypy.server.quickstart()
    cherrypy.engine.start(blocking=False)

You import memdebug, and call memdebug.start. That's all.

I haven't tried PySizer or Heapy. I would appreciate others' reviews.

UPDATE

The above code is for CherryPy 2.X, CherryPy 3.X the server.quickstart method has been removed and engine.start does not take the blocking flag. So if you are using CherryPy 3.X

# memdebug.py

import cherrypy
import dowser

def start(port):
    cherrypy.tree.mount(dowser.Root())
    cherrypy.config.update({
        'environment': 'embedded',
        'server.socket_port': port
    })
    cherrypy.engine.start()

You haven't provided any of your code from LightFactoryRemote, so this is only a presumption, but it looks like the kind of problem you'd be seeing if you were using the bindService method on it's own.

To ensure a service is kept running, even after the activity that started it has had its onDestroy method called, you should first use startService.

The android docs for startService state:

Using startService() overrides the default service lifetime that is managed by bindService(Intent, ServiceConnection, int): it requires the service to remain running until stopService(Intent) is called, regardless of whether any clients are connected to it.

Whereas for bindService:

The service will be considered required by the system only for as long as the calling context exists. For example, if this Context is an Activity that is stopped, the service will not be required to continue running until the Activity is resumed.

So what's happened is the activity that bound (and therefore started) the service, has been stopped and thus the system thinks the service is no longer required and causes that error (and then probably stops the service).

Example

In this example the service should be kept running regardless of whether the calling activity is running.

ComponentName myService = startService(new Intent(this, myClass.class));
bindService(new Intent(this, myClass.class), myServiceConn, BIND_AUTO_CREATE);

The first line starts the service, and the second binds it to the activity.

This will only works for everything except [0..2]

boolean isPositive = (n % (n - 1)) * n == n;

You can make a better solution like this (works except for [0..1])

boolean isPositive = ((n % (n - 0.5)) * n) / 0.5 == n;

You can get better precision by changing the 0.5 part with something like 2^m (m integer):

boolean isPositive = ((n % (n - 0.03125)) * n) / 0.03125 == n;

The Python pprint module actually already sorts dictionaries by key. In versions prior to Python 2.5, the sorting was only triggered on dictionaries whose pretty-printed representation spanned multiple lines, but in 2.5.X and 2.6.X, all dictionaries are sorted.

Generally, though, if you're writing data structures to a file and want them human-readable and writable, you might want to consider using an alternate format like YAML or JSON. Unless your users are themselves programmers, having them maintain configuration or application state dumped via pprint and loaded via eval can be a frustrating and error-prone task.

Use \r instead of \n.

Substituting by \n inserts a null character into the text. To get a newline, use \r. When searching for a newline, you’d still use \n, however. This asymmetry is due to the fact that \n and \r do slightly different things:

\n matches an end of line (newline), whereas \r matches a carriage return. On the other hand, in substitutions \n inserts a null character whereas \r inserts a newline (more precisely, it’s treated as the input CR). Here’s a small, non-interactive example to illustrate this, using the Vim command line feature (in other words, you can copy and paste the following into a terminal to run it). xxd shows a hexdump of the resulting file.

echo bar > test
(echo 'Before:'; xxd test) > output.txt
vim test '+s/b/\n/' '+s/a/\r/' +wq
(echo 'After:'; xxd test) >> output.txt
more output.txt

Before:
0000000: 6261 720a                                bar.
After:
0000000: 000a 720a                                ..r.

In other words, \n has inserted the byte 0x00 into the text; \r has inserted the byte 0x0a.

I have added line

$this->_productCollection->addAttributeToSelect('releasedate');

in

app/code/core/Mage/Catalog/Block/Product/List.php on line 95

in function _getProductCollection()

and then call it in

app/design/frontend/default/hellopress/template/catalog/product/list.phtml

By writing code

<div><?php echo $this->__('Release Date: %s', $this->dateFormat($_product->getReleasedate())) ?>
</div>

Now it is working in Magento 1.4.x

Don't know what you are doing (helpful to show what you tried that didn't work), but your claim that cex.axis only affects the x-axis is not true:

set.seed(123)
foo <- data.frame(X = rnorm(10), Y = rnorm(10))
plot(Y ~ X, data = foo, cex.axis = 3)

at least for me with:

Also, cex.axis affects the labelling of tick marks. cex.lab is used to control what R call the axis labels.

plot(Y ~ X, data = foo, cex.lab = 3)

but even that works for both the x- and y-axis.

Following up Jens' comment about using barplot(). Check out the cex.names argument to barplot(), which allows you to control the bar labels:

dat <- rpois(10, 3) names(dat) <- LETTERS[1:10] barplot(dat, cex.names = 3, cex.axis = 2)

As you mention that cex.axis was only affecting the x-axis I presume you had horiz = TRUE in your barplot() call as well? As the bar labels are not drawn with an axis() call, applying Joris' (otherwise very useful) answer with individual axis() calls won't help in this situation with you using barplot()

For those situations where you need a bit more customisation of the output (separator or decimal symbol), or who have large dataset (over 65k rows), I wrote the following:

    ar = rng
    f = FreeFile()
    Open fileName For Output As #f

    oldDec = Format(0, ".")     'current client's decimal symbol
    replaceDecimal = (decimalSign <> "") And (decimalSign <> oldDec)

From the Solution Explorer window select your form, right-click, click on View Designer. Voila! The form should display.

I tried posting a couple screenshots, but this is my first post; therefore, I could not post any images.

Where are you jar files? Is there a pattern to find where they are?

1. Are they all in one directory?

For example, foo/a/a.jar and foo/b/b.jar are all under the folder foo/, in this case, you could use find with grep:

find foo/ -name "*.jar" | xargs grep Hello.class

Sure, at least you can search them under the root directory /, but it will be slow.

As @loganaayahee said, you could also use the command locate. locate search the files with an index, so it will be faster. But the command should be:

locate "*.jar" | xargs grep Hello.class

Since you want to search the content of the jar files.

2. Are the paths stored in an environment variable?

Typically, Java will store the paths to find jar files in an environment variable like CLASS_PATH, I don't know if this is what you want. But if your variable is just like this:CLASS_PATH=/lib:/usr/lib:/bin, which use a : to separate the paths, then you could use this commend to search the class:

for P in `echo $CLASS_PATH | sed 's/:/ /g'`; do grep Hello.calss $P/*.jar; done

I got this error/exception in Visual Studio 2010 when I changed my build in the Configuration Manager dialog box from "x86" to "Any CPU". This OLEDB database driver I understand only works in x86 and is not 64bit compatible. Changing the build configuration back to x86 solved the problem for me.

i think that is the solution

ArrayList<table> libel = new ArrayList<table>();
try {
SessionFactory sf = new Configuration().configure().buildSessionFactory();
Session s = sf.openSession();
s.beginTransaction();

String hql = "FROM table ";

org.hibernate.Query query = s.createQuery(hql);
libel= (ArrayList<table>) query.list();
Iterator it = libel.iterator();
while(it.hasNext()) {
table cat = (table) it.next();

cat.getLibCat();//table colonm getter


combobox.addItem(cat.getLibCat());
}
s.getTransaction().commit();
s.close();
sf.close();
} catch (Exception e) {
System.out.println("Exception in getSelectedData::"+e.getMessage());

Disclaimer

There is a way to achieve this which is quite simple, but I wouldn't suggest it is a good approach for an app you are going to let other people see. But if you had some developer need to show the console and windows forms at the same time, it can be done quite easily.

This method also supports showing only the Console window, but does not support showing only the Windows Form - i.e. the Console will always be shown. You can only interact (i.e. receive data - Console.ReadLine(), Console.Read()) with the console window if you do not show the windows forms; output to Console - Console.WriteLine() - works in both modes.

This is provided as is; no guarantees this won't do something horrible later on, but it does work.

Project steps

Start from a standard Console Application.

Mark the Main method as [STAThread]

Add a reference in your project to System.Windows.Forms

Add a Windows Form to your project.

Add the standard Windows start code to your Main method:

End Result

You will have an application that shows the Console and optionally windows forms.

Sample Code

Program.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace ConsoleApplication9 {
    class Program {

        [STAThread]
        static void Main(string[] args) {

            if (args.Length > 0 && args[0] == "console") {
                Console.WriteLine("Hello world!");
                Console.ReadLine();
            }
            else {
                Application.EnableVisualStyles(); 
                Application.SetCompatibleTextRenderingDefault(false); 
                Application.Run(new Form1());
            }
        }
    }
}

Form1.cs

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace ConsoleApplication9 {
    public partial class Form1 : Form {
        public Form1() {
            InitializeComponent();
        }

        private void Form1_Click(object sender, EventArgs e) {
            Console.WriteLine("Clicked");
        }
    }
}

Generally, EXC_BAD_INSTRUCTION means that there was an assertion failure in your code. A wild guess, your Screen.text is not an integer. Double check its type.

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;"

You can achieve this by utilizing the jsPDF library and the toDataURL function.

I made a little demonstration:

var context = canvas.getContext('2d');_x000D_
_x000D_

context.beginPath();_x000D_
context.moveTo(170, 80);_x000D_
context.bezierCurveTo(130, 100, 130, 150, 230, 150);_x000D_
context.bezierCurveTo(250, 180, 320, 180, 340, 150);_x000D_
context.bezierCurveTo(420, 150, 420, 120, 390, 100);_x000D_
context.bezierCurveTo(430, 40, 370, 30, 340, 50);_x000D_
context.bezierCurveTo(320, 5, 250, 20, 250, 50);_x000D_
context.bezierCurveTo(200, 5, 150, 20, 170, 80);_x000D_
context.closePath();_x000D_
context.lineWidth = 5;_x000D_
context.fillStyle = '#8ED6FF';_x000D_
context.fill();_x000D_
context.strokeStyle = '#0000ff';_x000D_
context.stroke();_x000D_

Your suggested solution only waits for DOM readyState to signal complete. But Selenium by default tries to wait for those (and a little bit more) on page loads via the driver.get() and element.click() methods. They are already blocking, they wait for the page to fully load and those should be working ok.

Problem, obviously, are redirects via AJAX requests and running scripts - those can't be caught by Selenium, it doesn't wait for them to finish. Also, you can't reliably catch them via readyState - it waits for a bit, which can be useful, but it will signal complete long before all the AJAX content is downloaded.

There is no general solution that would work everywhere and for everyone, that's why it's hard and everyone uses something a little bit different.

The general rule is to rely on WebDriver to do his part, then use implicit waits, then use explicit waits for elements you want to assert on the page, but there's a lot more techniques that can be done. You should pick the one (or a combination of several of them) that works best in your case, on your tested page.

See my two answers regarding this for more information:

• How I can check whether page is loaded completely or not in web driver
• Selenium Webdriver : Wait for complex page with javascript to load

I had this other solution (I'm posting it in case someone else as me is using the following method from the model):

class onlyUserIsActiveField(forms.ModelForm):
    def __init__(self, *args, **kwargs):
        super(onlyUserIsActiveField, self).__init__(*args, **kwargs)
        self.fields['is_active'].initial = False

    class Meta:
        model = User
        fields = ['is_active']
        labels = {'is_active': 'Is Active'}
        widgets = {
            'is_active': forms.CheckboxInput( attrs={
                            'class':          'form-control bootstrap-switch',
                            'data-size':      'mini',
                            'data-on-color':  'success',
                            'data-on-text':   'Active',
                            'data-off-color': 'danger',
                            'data-off-text':  'Inactive',
                            'name':           'is_active',

            })
        }

The initial is definded on the __init__ function as self.fields['is_active'].initial = False

struct Bool {
    int true;
    int false;
}

int main() {

    /* bool is a variable of data type – bool*/
    struct Bool bool;

    /*below I’m accessing struct members through variable –bool*/ 
    bool = {1,0};
    print("Student Name is: %s", bool.true);
    return 0;
}

1. Control-click your connection and choose Connection Properties.
2. Under Advanced tab, set the Socket Timeout (sec) to a larger value.

I was getting the same error. In my case there was a leading space-symbol in the fxml file name:

" fxml_example.fxml" instead of "fxml_example.fxml"

I don't know where it came from. It was very difficult to notice it. When I removed the leading space, everything went ok. I didn't even knew that file name could start with the space-symbol.

1.84E-07 is the exact value, represented using scientific notation, also known as exponential notation.

1.845E-07 is the same as 0.0000001845. Excel will display a number very close to 0 as 0, unless you modify the formatting of the cell to display more decimals.

C# however will get the actual value from the cell. The ToString method use the e-notation when converting small numbers to a string.

You can specify a format string if you don't want to use the e-notation.

This is a modern approach and it utilizes the CSS Flexbox functionality. You can now vertically align the content within your parent container by just adding these styles to the .main container

.main {
        display: flex;
        flex-direction: column;
        justify-content: center;
}

And you are good to go!

While not as pretty as querySelectorAll (which has a litany of issues), here's a very flexible function that recurses the DOM and should work in most browsers (old and new). As long as the browser supports your condition (ie: data attributes), you should be able to retrieve the element.

To the curious: Don't bother testing this vs. QSA on jsPerf. Browsers like Opera 11 will cache the query and skew the results.

Code:

function recurseDOM(start, whitelist)
{
    /*
    *    @start:        Node    -    Specifies point of entry for recursion
    *    @whitelist:    Object  -    Specifies permitted nodeTypes to collect
    */

    var i = 0, 
    startIsNode = !!start && !!start.nodeType, 
    startHasChildNodes = !!start.childNodes && !!start.childNodes.length,
    nodes, node, nodeHasChildNodes;
    if(startIsNode && startHasChildNodes)
    {       
        nodes = start.childNodes;
        for(i;i<nodes.length;i++)
        {
            node = nodes[i];
            nodeHasChildNodes = !!node.childNodes && !!node.childNodes.length;
            if(!whitelist || whitelist[node.nodeType])
            {
                //condition here
                if(!!node.dataset && !!node.dataset.foo)
                {
                    //handle results here
                }
                if(nodeHasChildNodes)
                {
                    recurseDOM(node, whitelist);
                }
            }
            node = null;
            nodeHasChildNodes = null;
        }
    }
}

You can then initiate it with the following:

recurseDOM(document.body, {"1": 1}); for speed, or just recurseDOM(document.body);

install "SQL Express 2005 service pack 4" version "directly".

it contains sql Express 2005 inside . dont let the name fool you

runs succesfuly. from my experince

You will learn the way to do it, in an easy way, is:

public class Mtest extends Activity {
  Button b1;
  Button b2;
  public void onCreate(Bundle savedInstanceState) {
    ...
    b1 = (Button) findViewById(R.id.b1);
    b2 = (Button) findViewById(R.id.b2);
    b1.setOnClickListener(myhandler1);
    b2.setOnClickListener(myhandler2);
    ...
  }
  View.OnClickListener myhandler1 = new View.OnClickListener() {
    public void onClick(View v) {
      // it was the 1st button
    }
  };
  View.OnClickListener myhandler2 = new View.OnClickListener() {
    public void onClick(View v) {
      // it was the 2nd button
    }
  };
}

Or, if you are working with just one clicklistener, you can do:

View.OnClickListener myOnlyhandler = new View.OnClickListener() {
  public void onClick(View v) {
      switch(v.getId()) {
        case R.id.b1:
          // it was the first button
          break;
        case R.id.b2:
          // it was the second button
          break;
      }
  }
}

Though, I don't recommend doing it that way since you will have to add an if for each button you use. That's hard to maintain.

I'd start by not calling it list, since that's the name of the constructor for Python's built in list type.

But once you've renamed it to cities or something, you'd do:

print(cities[0][0], cities[1][0])
print(cities[0][1], cities[1][1])

Any seaborn plots suported by facetgrid won't work with (e.g. catplot)

g.set_xticklabels(rotation=30) 

however barplot, countplot, etc. will work as they are not supported by facetgrid. Below will work for them.

g.set_xticklabels(g.get_xticklabels(), rotation=30)

Also, in case you have 2 graphs overlayed on top of each other, try set_xticklabels on graph which supports it.

Quoting spaces inside variables such that the shell will re-interpret things properly is hard. It's this type of thing that prompts me to reach for a stronger language. Whether that's perl or python or ruby or whatever (I choose perl, but that's not always for everyone), it's just something that will allow you to bypass the shell for quoting.

It's not that I've never managed to get it right with liberal doses of eval, but just that eval gives me the eebie-jeebies (becomes a whole new headache when you want to take user input and eval it, though in this case you'd be taking stuff that you wrote and evaling that instead), and that I've gotten headaches in debugging.

With perl, as my example, I'd be able to do something like:

@tar_cmd = ( qw(tar cv), $directory );
@encrypt_cmd = ( qw(openssl des3 -salt) );
@split_cmd = ( qw(split -b 1024m -), $backup_file );

The hard part here is doing the pipes - but a bit of IO::Pipe, fork, and reopening stdout and stderr, and it's not bad. Some would say that's worse than quoting the shell properly, and I understand where they're coming from, but, for me, this is easier to read, maintain, and write. Heck, someone could take the hard work out of this and create a IO::Pipeline module and make the whole thing trivial ;-)
