Calculate the intersection point of the lines laying on your segments (it means basically to solve a linear equation system), then check whether is it between the starting and ending points of your segments.

There is an easier way to get the exact version .NET version installed on your machine from a cmd prompt. Just follow the following instructions;

Open the command prompt (i.e Windows + R ? type “cmd”) and type the following command, all on one line: %windir%\Microsoft.NET\FrameWork, and then navigating to the directory with the latest version number.

Refer to http://dotnettec.com/check-dot-net-framework-version/

I would use @HostListener decorator within your component:

import { HostListener } from '@angular/core';

@Component({
  ...
})
export class AppComponent {

  @HostListener('document:keypress', ['$event'])
  handleKeyboardEvent(event: KeyboardEvent) { 
    this.key = event.key;
  }
}

There are also other options like:

host property within @Component decorator

Angular recommends using @HostListener decorator over host property https://angular.io/guide/styleguide#style-06-03

@Component({
  ...
  host: {
    '(document:keypress)': 'handleKeyboardEvent($event)'
  }
})
export class AppComponent {
  handleKeyboardEvent(event: KeyboardEvent) {
    console.log(event);
  }
}

renderer.listen

import { Component, Renderer2 } from '@angular/core';

@Component({
  ...
})
export class AppComponent {
  globalListenFunc: Function;

  constructor(private renderer: Renderer2) {}

  ngOnInit() {
    this.globalListenFunc = this.renderer.listen('document', 'keypress', e => {
      console.log(e);
    });
  }

  ngOnDestroy() {
    // remove listener
    this.globalListenFunc();
  }
}

Observable.fromEvent

import { Observable } from 'rxjs/Observable';
import 'rxjs/add/observable/fromEvent';
import { Subscription } from 'rxjs/Subscription';

@Component({
  ...
})
export class AppComponent {
  subscription: Subscription;

  ngOnInit() {
    this.subscription = Observable.fromEvent(document, 'keypress').subscribe(e => {
      console.log(e);
    })
  }

  ngOnDestroy() {
    this.subscription.unsubscribe();
  }
}

The error is pretty clear, you need to specify an absolute (instead of relative) path and/or set root in the config object for res.sendFile(). Examples:

// assuming index.html is in the same directory as this script

res.sendFile(__dirname + '/index.html');

or specify a root (which is used as the base path for the first argument to res.sendFile():

res.sendFile('index.html', { root: __dirname });

Specifying the root path is more useful when you're passing a user-generated file path which could potentially contain malformed/malicious parts like .. (e.g. ../../../../../../etc/passwd). Setting the root path prevents such malicious paths from being used to access files outside of that base path.

I was using View.INVISIBLE and View.VISIBLE and the ProgressBar would slowly flash instead of constantly being visible, switched to View.GONE and View.VISIBLE and it works perfectly

You could create a user form:

http://www.excel-vba-easy.com/vba-userform-excel-vba.html

The simpliest way to do it is to use CancelableCallback. You should check the first action is complete and then call the second:

mMap.animateCamera(CameraUpdateFactory.newLatLngBounds(bounds, size.x, height, 0), new CancelableCallback() {

                @Override
                public void onFinish() {
                    CameraUpdate cu_scroll = CameraUpdateFactory.scrollBy(0, 500);
                    mMap.animateCamera(cu_scroll);
                }

                @Override
                public void onCancel() {
                }
            });

If the browser that you are planning to use is Mozilla (Addon development) (not sure of chrome) you can use the following method in Javascript

function DOM( string )
{
    var {Cc, Ci} = require("chrome");
    var parser = Cc["@mozilla.org/xmlextras/domparser;1"].createInstance(Ci.nsIDOMParser);
    console.log("PARSING OF DOM COMPLETED ...");
    return (parser.parseFromString(string, "text/html"));
};

Hope this helps

I made a **

automatic-network-drive connector

** using a batch file.

Suddenly there was a networkdrive called "Data for Analysation", and yeah with the double quotes it works proper!

looks a little bit different but works:

net use y: "\\share.blabla.com\Folder\Subfolder\Data for Analysation" /USER:domain\username PW /PERSISTENT:YES

Thx for the Hint :)

Unless you have some really compelling reason not to, I suggest ditching the MS JDBC driver.

Instead, use the jtds jdbc driver. Read the README.SSO file in the jtds distribution on how to configure for single-sign-on (native authentication) and where to put the native DLL to ensure it can be loaded by the JVM.

You can use RegExMatch:

=IF(RegExMatch(A1;"Bla");"YES";"NO")

If you want to remove ALL whitespace, even newlines:

perl -pe 's/\s+//g' file

I was getting this error:

The type com.ibm.portal.state.exceptions.StateException cannot be resolved. It is indirectly referenced from required .class files

Doing the following fixed it for me:

Properties -> Java build path -> Libraries -> Server Library[wps.base.v61]unbound -> Websphere Portal v6.1 on WAS 7 -> Finish -> OK

use the val() function

You need to specify the radix. There's an overload of Integer#parseInt() which allows you to.

int foo = Integer.parseInt("1001", 2);

If the function is from a source file available on the filesystem, then inspect.getsource(foo) might be of help:

If foo is defined as:

def foo(arg1,arg2):         
    #do something with args 
    a = arg1 + arg2         
    return a  

Then:

import inspect
lines = inspect.getsource(foo)
print(lines)

Returns:

def foo(arg1,arg2):         
    #do something with args 
    a = arg1 + arg2         
    return a                

But I believe that if the function is compiled from a string, stream or imported from a compiled file, then you cannot retrieve its source code.

I seem to have found something that worked for me which no one else mentioned.

# Ignore everything
*

# But not these files...
!.gitignore
!script.pl
!template.latex
# etc...

# And if you want to include a sub-directory and all sub-directory and files under it, but not all sub-directories
!subdir/
!subdir/**/*

Basically, it seems to negate a sub-directory from being ignored, you have to have two entries, one for the sub-directory itself !subdir/ and then another one which expands to all files and folders under it !subdir/**/*

Javascript's logical OR operator is short-circuiting and can replace your "Elvis" operator:

var displayName = user.name || "Anonymous";

However, to my knowledge there's no equivalent to your ?. operator.

try to use this

<RadioGroup
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"       
    android:orientation="horizontal"

this is java class

public void onRadioButtonClicked(View view) {
        // Is the button now checked?
        boolean checked = ((RadioButton) view).isChecked();

        // Check which radio button was clicked
        switch(view.getId()) {
            case R.id.standard_delivery:
                if (checked)
                    Toast.makeText(DishActivity.this," standard delivery",Toast.LENGTH_LONG).show();
                    break;
            case R.id.midnight_delivery:
                if (checked)
                    Toast.makeText(DishActivity.this," midnight delivery",Toast.LENGTH_LONG).show();
                    break;
        }
    }

Another cause for this might be case-insensitive file systems. If you have multiple folders in your repo on the same level whose names only differ by case, you will get hit by this. Browse the source repository using its web interface (e.g. GitHub or VSTS) to make sure.

That doesn't work because a member function pointer cannot be handled like a normal function pointer, because it expects a "this" object argument.

Instead you can pass a static member function as follows, which are like normal non-member functions in this regard:

m_cRedundencyManager->Init(&CLoggersInfra::Callback, this);

The function can be defined as follows

static void Callback(int other_arg, void * this_pointer) {
    CLoggersInfra * self = static_cast<CLoggersInfra*>(this_pointer);
    self->RedundencyManagerCallBack(other_arg);
}

Incase you have multiple versions of Postgres installed on your machine. You can remove all via brew command as:

brew uninstall --force postgresql

This isn't quite what you're looking for, but I've found it useful in similar circumstances.

I recently added the following to my $HOME/.bashrc (something similar should be possible with shells other than bash):

if [ -f $HOME/.add-screen-to-history ] ; then
    history -s 'screen -dr'
fi

I keep a screen session running on one particular machine, and I've had problems with ssh connections to that machine being dropped, requiring me to re-run screen -dr every time I reconnect.

With that addition, and after creating that (empty) file in my home directory, I automatically have the screen -dr command in my history when my shell starts. After reconnecting, I can just type Control-P Enter and I'm back in my screen session -- or I can ignore it. It's flexible, but not quite automatic, and in your case it's easier than typing tmux list-sessions.

You might want to make the history -s command unconditional.

This does require updating your $HOME/.bashrc on each of the target systems, which might or might not make it unsuitable for your purposes.

First, download the NuGet command line tool from here.

Next, open a command prompt and cd to the directory to which nuget.exe was downloaded.

You can list the local caches with this command:

nuget locals all -list

You can clear all caches with this command:

nuget locals all -clear

Reference: https://docs.nuget.org/consume/command-line-reference

You can do it like this,

<input type="text" name="name" value="<?php echo $name;?>" />

But seen as you've taken it straight from user input, you want to sanitize it first so that nothing nasty is put into the output of your page.

<input type="text" name="name" value="<?php echo htmlspecialchars($name);?>" />

A simple git fetch/pull command will throw a authentication failed message. But do the same git fetch/pull command second time, and it should prompt a window asking for credential(username/password). Enter your Id and new password and it should save and move on.

What about ordering desc by the desired property,

   blah = blah.OrderByDescending(x => x.Property);

And then doing something like

  if (!descending)
  {

Is it Reverse() too slow?

It depends on the nature of your application. And, since you did not describe it in great detail, it is an impossible question to answer. I find Backbone to be the easiest, but I work in Angular all day. Performance is more up to the coder than the framework, in my opinion.

Are you doing heavy DOM manipulation? I would use jQuery and Backbone.

Very data driven app? Angular with its nice data binding.

Game programming? None - direct to canvas; maybe a game engine.

I used SSH.Net in a project a while ago and was very happy with it. It also comes with a good documentation with lots of samples on how to use it.

The original package website can be still found here, including the documentation (which currently isn't available on GitHub).

For your case the code would be something like this.

using (var client = new SshClient("hostnameOrIp", "username", "password"))
{
    client.Connect();
    client.RunCommand("etc/init.d/networking restart");
    client.Disconnect();
}

When you delete innodb tables, MySQL does not free the space inside the ibdata file, that's why it keeps growing. These files hardly ever shrink.

How to shrink an existing ibdata file:

https://dev.mysql.com/doc/refman/5.6/en/innodb-system-tablespace.html#innodb-resize-system-tablespace

You can script this and schedule the script to run after a fixed period of time, but for the setup described above it seems that multiple tablespaces are an easier solution.

If you use the configuration option innodb_file_per_table, you create multiple tablespaces. That is, MySQL creates separate files for each table instead of one shared file. These separate files a stored in the directory of the database, and they are deleted when you delete this database. This should remove the need to shrink/purge ibdata files in your case.

More information about multiple tablespaces:

https://dev.mysql.com/doc/refman/5.6/en/innodb-file-per-table-tablespaces.html

tl;dr

Let the modern java.time classes of JSR 310 automatically generate localized text, rather than hard-coding 12-hour clock and AM/PM.

LocalTime                                     // Represent a time-of-day, without date, without time zone or offset-from-UTC.
.now(                                         // Capture the current time-of-day as seen in a particular time zone.
    ZoneId.of( "Africa/Casablanca" )          
)                                             // Returns a `LocalTime` object.
.format(                                      // Generate text representing the value in our `LocalTime` object.
    DateTimeFormatter                         // Class responsible for generating text representing the value of a java.time object.
    .ofLocalizedTime(                         // Automatically localize the text being generated.
        FormatStyle.SHORT                     // Specify how long or abbreviated the generated text should be.
    )                                         // Returns a `DateTimeFormatter` object.
    .withLocale( Locale.US )                  // Specifies a particular locale for the `DateTimeFormatter` rather than rely on the JVM’s current default locale. Returns another separate `DateTimeFormatter` object rather than altering the first, per immutable objects pattern.
)                                             // Returns a `String` object.

Automatically localize

Rather than insisting on 12-hour clock with AM/PM, you may want to let java.time automatically localize for you. Call DateTimeFormatter.ofLocalizedTime.

To localize, specify:

• FormatStyle to determine how long or abbreviated should the string be.
• Locale to determine:
  • The human language for translation of name of day, name of month, and such.
  • The cultural norms deciding issues of abbreviation, capitalization, punctuation, separators, and such.

Here we get the current time-of-day as seen in a particular time zone. Then we generate text to represent that time. We localize to French language in Canada culture, then English language in US culture.

ZoneId z = ZoneId.of( "Asia/Tokyo" ) ;
LocalTime localTime = LocalTime.now( z ) ;

// Québec
Locale locale_fr_CA = Locale.CANADA_FRENCH ;  // Or `Locale.US`, and so on.
DateTimeFormatter formatterQuébec = DateTimeFormatter.ofLocalizedTime( FormatStyle.SHORT ).withLocale( locale_fr_CA ) ;
String outputQuébec = localTime.format( formatterQuébec ) ;

System.out.println( outputQuébec ) ;

// US
Locale locale_en_US = Locale.US ;  
DateTimeFormatter formatterUS = DateTimeFormatter.ofLocalizedTime( FormatStyle.SHORT ).withLocale( locale_en_US ) ;
String outputUS = localTime.format( formatterUS ) ;

System.out.println( outputUS ) ;

They have the same speed. Maybe in some special architecture what he/she said is right, but in the x86 family at least I know they are the same. Because for doing this the CPU will do a substraction (a - b) and then check the flags of the flag register. Two bits of that register are called ZF (zero Flag) and SF (sign flag), and it is done in one cycle, because it will do it with one mask operation.

A cleaned up Python 3 example:

# inputExample.py

def confirm_input(question, default="no"):
    """Ask a yes/no question and return their answer.

    "question" is a string that is presented to the user.
    "default" is the presumed answer if the user just hits <Enter>.
        It must be "yes", "no", or None (meaning
        an answer is required of the user).

    The "answer" return value is True for "yes" or False for "no".
    """
    valid = {"yes": True, "y": True, "ye": True,
             "no": False, "n": False}
    if default is None:
        prompt = " [y/n] "
    elif default == "yes":
        prompt = " [Y/n] "
    elif default == "no":
        prompt = " [y/N] "
    else:
        raise ValueError("invalid default answer: '{}}'".format(default))

    while True:
        print(question + prompt)
        choice = input().lower()
        if default is not None and choice == '':
            return valid[default]
        elif choice in valid:
            return valid[choice]
        else:
            print("Please respond with 'yes' or 'no' "
                             "(or 'y' or 'n').\n")

def main():

    if confirm_input("\nDo you want to continue? "):
        print("You said yes because the function equals true. Continuing.")
    else:
        print("Quitting because the function equals false.")

if __name__ == "__main__":
    main()

In my case the solution was:

Permissions on the config file should be 600. chmod 600 config

As mentioned in the comments above by generalopinion

No need to touch the config file contents.

I actually just found this today for something I'm working on. This will return file paths for all files in a folder and its subfolders.

     filepath(n) = vFile
     filename = fso.GetFileName(vFile) 'If you want the filename without full path
     n=n+1
Next vFile


'These two functions are required
Public Function RecursiveDir(colFiles As Collection, strFolder As String, strFileSpec As String, bIncludeSubfolders As Boolean)
Dim strTemp As String
Dim colFolders As New Collection

    strTemp = Dir
Loop
If bIncludeSubfolders Then

    strTemp = Dir(strFolder, vbDirectory)

If class has only one empty constructor (like Activity or Fragment etc, android classes):

Class<?> myClass = Class.forName("com.example.MyClass");    
Constructor<?> constructor = myClass.getConstructors()[0];

Right here: http://jt400.sourceforge.net/

This is what I use for that exact purpose.

EDIT: Usage Examples (minus exceptions):

// Driver initialization
AS400JDBCDriver driver = new com.ibm.as400.access.AS400JDBCDriver();
DriverManager.registerDriver(driver);

// JDBC Connection URL
String url = "jdbc:as400://10.10.10.10" + ";promt=false" // disable GUI prompting by jt400 library

// Get a Connection object (this is used to create statements, etc)
Connection conn = DriverManager.getConnection(url, UserString, PassString);

Hope that helps!

A slightly nicer way of measuring execution time, is to use the rbenchmark package. This package (easily) allows you to specify how many times to replicate your test and would the relative benchmark should be.

None of the proposed answers completely worked for me. My use case is slightly different (doing an ajax get to an S3 .json file in IE9). Setting jQuery.support.cors = true; got rid of the No Transport error but I was still getting Permission denied errors.

What did work for me was to use the jQuery-ajaxTransport-XDomainRequest to force IE9 to use XDomainRequest. Using this did not require setting jQuery.support.cors = true;

1. Click on Window > Show view > Server or right click on the server in "Servers" view, select "Properties".
2. In the "General" panel, click on the "Switch Location" button.
3. The "Location: [workspace metadata]" should replace by something else.
4. Open the Overview screen for the server by double clicking it.
5. In the Server locations tab , select "Use Tomcat location".
6. Save the configurations and restart the Server.

You may want to follow the steps above before starting the server. Because server location section goes grayed-unreachable.

As someone that has ran into this problem constantly with java repositories on Windows, the best solution is to install Cygwin (https://www.cygwin.com/) and use its git installation under all > devel > git.

The reason this is the best solution I have come across is since Cygwin manages the long path names so other provided commands benefit. Ex: find, cp and rm. Trust me, the real problem begins when you have to delete path names that are too long in Windows.

What I do is use Object.keys() to return a list of all the keys and then get the length of that

Object.keys(dictionary).length

Here is a complete screenshot example that works with chrome in 2021. The end result is a blob ready to be transmitted. Flow is: request media > grab frame > draw to canvas > transfer to blob. If you want to do it more memory efficient explore OffscreenCanvas or possibly ImageBitmapRenderingContext

https://jsfiddle.net/v24hyd3q/1/

// Request media
navigator.mediaDevices.getDisplayMedia().then(stream =>

  // Grab frame from stream
  let track = stream.getVideoTracks()[0];
  let capture = new ImageCapture(track);
  capture.grabFrame().then(bitmap => 
  {
    // Stop sharing
    track.stop();
      
    // Draw the bitmap to canvas
    canvas.width = bitmap.width;
    canvas.height = bitmap.height;
    canvas.getContext('2d').drawImage(bitmap, 0, 0);
      
    // Grab blob from canvas
    canvas.toBlob(blob => {
        // Do things with blob here
        console.log('output blob:', blob);
    });

No, you cannot know when a page was last updated or last changed or uploaded to a server (which might, depending on interpretation, be three different things) just by accessing the page.

A server may, and should (according to the HTTP 1.1 protocol), send a Last-Modified header, which you can find out in several ways, e.g. using Rex Swain’s HTTP Viewer. However, according to the protocol, this is just

“the date and time at which the origin server believes the variant was last modified”.

And the protocol realistically adds:

“The exact meaning of this header field depends on the implementation of the origin server and the nature of the original resource. For files, it may be just the file system last-modified time. For entities with dynamically included parts, it may be the most recent of the set of last-modify times for its component parts. For database gateways, it may be the last-update time stamp of the record. For virtual objects, it may be the last time the internal state changed.”

In practice, web pages are very often dynamically created from a Content Management System or otherwise, and in such cases, the Last-Modified header typically shows a data stamp of creating the response, which is normally very close to the time of the request. This means that the header is practically useless in such cases.

Even in the case of a “static” page (the server simply picks up a file matching the request and sends it), the Last-Modified date stamp normally indicates just the last write access to the file on the server. This might relate to a time when the file was restored from a backup copy, or a time when the file was edited on the server without making any change to the content, or a time when it was uploaded onto the server, possibly replacing an older identical copy. In these cases, assuming that the time stamp is technically correct, it indicates a time after which the page has not been changed (but not necessarily the time of last change).

jQuery UI Touch Punch just solves it all.

It's a Touch Event Support for jQuery UI. Basically, it just wires touch event back to jQuery UI. Tested on iPad, iPhone, Android and other touch-enabled mobile devices. I used jQuery UI sortable and it works like a charm.

If you are a vim purist, skip reading this answer. OTOH, if you are new to vim and are looking for a few helpful tips you wont find in the many hundred of vim tutorials and blogs, read on... :-)

A few un-orthodox (vim) ways

It's 2014, and as someone who's recently gone back to vim I can offer a few, potentially contrarian, points of view and tips.

Use shift+left or shift+right to traverse words

While repetition is a powerful concept in vim, I (personally) find it strange that using it either forces me to count (lines, characters, words, etc.) or make guesses. My brain usually works like "I want the cursor there" and not like "I want the cursor _5_words_to_the_left_". Quickly being able to move the cursor, and visually observe where the insertion point this way allows me to keep my mind on what I'm editing instead of having to count how many hops I need to make to get to where I need to edit.

Turn on mouse mode, and use the mouse wheel and clicking

...to navigate large bodies of text.

Most (all) modern computers have a touchpad that is closely integrated with the keyboard (e.g. MacBooks). Industrial designers have spent many man years optimizing these designs so that the old problem of having to move the hand away from the keyboard is no longer a real issue. Okay, it is if you are used to a mouse and don't like to switch, but for anyone new to vim (like those that might find this post via a search), this should not be much of an issue.

As a bonus, click + drag puts you in visual mode

With mouse enabled, clicking and dragging has the effect of switching to visual mode and marking a region for yanking.

And use the scroll wheel

Using the mouse (wheel) to scroll around, and clicking to position the cursor (duh) just works. See http://usevim.com/2012/05/16/mouse/ for more on this.

And so...

These are what I'd call more modern (using mouse, scroll wheel, etc.) ways of navigating in vim, equally effective depending on your preference of input.

HTH

More accurately anything that is not 0 is true.

So 1 is true, but so is 2, 3 ... etc.

@boernard 's answer solves this from the Android Studio IDE, but if you want to understand what's happening under the covers, it's a simple gradle build file update:

You can edit the build.gradle file from within the IDE (left pane: Gradle Scripts -> build.gradle (Module: app)) or use the raw path (<proj_dir>/app/build.gradle) and add/update the following dependency section:

dependencies {
    //
    // IDE setting pulls in the specific version of v4 support you have installed:
    //
    //compile 'com.android.support:support-v4:21.0.3'

    //
    // generic directive pulls in any available version of v4 support:
    //
    compile 'com.android.support:support-v4:+'
}

Using the above generic compile directive, allows you to ship your code to anyone, provided they have some level of the Android Support Libraries v4 installed.

When I received this error I believe it was a bug, however you should keep in mind that if you do a separate query with a SELECT statement and the same WHERE clause, then you can grab the primary ID's from that SELECT: SELECT CONCAT(primary_id, ',')) statement and insert them into the failed UPDATE query with conditions -> "WHERE [primary_id] IN ([list of comma-separated primary ID's from the SELECT statement)" which allows you to alleviate any issues being caused by the original (failed) query's WHERE clause.

For me, personally, when I was using quotes for the values in the "WHERE ____ IN ([values here])", only 10 of the 300 expected entries were being affected which, in my opinion, seems like a bug.

an Activity is a specialization of Context so, if you have a Context you already know which activity you intend to use and can simply cast a into c; where a is an Activity and c is a Context.

Activity a = (Activity) c;

HttpUtility.UrlEncode / Decode

You can add a reference to the System.Web assembly if it's not available in your project

It's easy to believe that deleting the whole Subversion repository requires "informing" Subversion that you're going to delete the repository. But Subversion only cares about managing a repository once it's created, not whether the repository exists or not ( if that makes sense ). It goes like this: the Subversion tools and commands are not adversely affected by just deleting your repository directory with the regular operating system utilities (like rm -R). A repository directory is not the same thing as an installed program directory, where deleting a program without uninstalling it might leave behind erratic config files or other dependencies. A repository is 100% self-contained in its directory, and deleting it is harmless (besides losing your project history). You just clean the slate to create a new Subversion repository and import your next project.

For image tag you can use this type of style, it worked for me:

imageStyle: {
    width: Dimensions.get('window').width - 23,
    resizeMode: "contain",
    height: 211,
 },

You must to set by this order:

<link rel="stylesheet" href="path/bootstrap.min.css">
 <style type="text/css">
      @font-face {
  font-family: 'Glyphicons Halflings';
        src: url('../fonts/glyphicons-halflings-regular.eot');
        src: url('../fonts/glyphicons-halflings-regular.eot?#iefix') format('embedded-opentype'),       url('../fonts/glyphicons-halflings-regular.woff') format('woff'),        url('../fonts/glyphicons-halflings-regular.ttf') format('truetype'),       url('../fonts/glyphicons-halflings-regular.svg#glyphicons-halflingsregular') format('svg');
}
 </style>

Your app is crashing at:

welcomePlayer.setText("Welcome Back, " + String.valueOf(mPlayer.getName(this)) + " !");

because mPlayer=null.

You forgot to initialize Player mPlayer in your PlayGame Activity.

mPlayer = new Player(context,"");

I, too, have this problem on an older Mac that I upgraded to Lion.

Before reading the terminfo tip, I was able to get vi and less working by doing "export TERM=xterm".

After reading the tip, I grabbed /usr/share/terminfo from a newer Mac that has fresh install of Lion and does not exhibit this problem.

Now, even though echo $TERM still yields xterm-256color, vi and less now work fine.

Am going to try and add value to this very good question and to build on @BrittonKerin's question in one of the comments under @David Wolever's fantastic answer. Wanted to share here because I had the same challenge as @BrittonKerin and I got something working (i.e. just want to run a piece of code only IF the table doesn't exist).

        # for completeness lets do the routine thing of connections and cursors
        conn = sqlite3.connect(db_file, timeout=1000) 

        cursor = conn.cursor() 

        # get the count of tables with the name  
        tablename = 'KABOOM' 
        cursor.execute("SELECT count(name) FROM sqlite_master WHERE type='table' AND name=? ", (tablename, ))

        print(cursor.fetchone()) # this SHOULD BE in a tuple containing count(name) integer.

        # check if the db has existing table named KABOOM
        # if the count is 1, then table exists 
        if cursor.fetchone()[0] ==1 : 
            print('Table exists. I can do my custom stuff here now.... ')
            pass
        else: 
           # then table doesn't exist. 
           custRET = myCustFunc(foo,bar) # replace this with your custom logic

I don't know if this solves your problem but instead of:

$("#tbIntervalos").find("td").attr("id", horaInicial);

you can just do:

$("#tbIntervalos td#" + horaInicial);

Check this

double[] myarray = ...;
System.out.println(myarray[myarray.length-1]); //last
System.out.println(myarray[0]); //first

Please note that C# and C++'s % operator is actually NOT a modulo, it's remainder. The formula for modulo that you want, in your case, is:

float nfmod(float a,float b)
{
    return a - b * floor(a / b);
}

You have to recode this in C# (or C++) but this is the way you get modulo and not a remainder.

When spring instantiates beans, it looks for a couple of interfaces like ApplicationContextAware and InitializingBean. If they are found, the methods are invoked. E.g. (very simplified)

Class<?> beanClass = beanDefinition.getClass();
Object bean = beanClass.newInstance();
if (bean instanceof ApplicationContextAware) {
    ((ApplicationContextAware) bean).setApplicationContext(ctx);
}

Note that in newer version it may be better to use annotations, rather than implementing spring-specific interfaces. Now you can simply use:

@Inject // or @Autowired
private ApplicationContext ctx;

After reading Misko's articles I believe that static methods are bad from a testing point of view. You should have factories instead(maybe using a dependency injection tool like Guice).

how do I ensure that I only have one of something

only have one of something The problem of “how do I ensure that I only have one of something” is nicely sidestepped. You instantiate only a single ApplicationFactory in your main, and as a result, you only instantiate a single instance of all of your singletons.

The basic issue with static methods is they are procedural code

The basic issue with static methods is they are procedural code. I have no idea how to unit-test procedural code. Unit-testing assumes that I can instantiate a piece of my application in isolation. During the instantiation I wire the dependencies with mocks/friendlies which replace the real dependencies. With procedural programing there is nothing to "wire" since there are no objects, the code and data are separate.

The top answer is flawed in my opinion. Hopefully, no one is mass importing all of pandas into their namespace with from pandas import *. Also, the map method should be reserved for those times when passing it a dictionary or Series. It can take a function but this is what apply is used for.

So, if you must use the above approach, I would write it like this

df["A1"], df["A2"] = zip(*df["a"].apply(calculate))

There's actually no reason to use zip here. You can simply do this:

df["A1"], df["A2"] = calculate(df['a'])

This second method is also much faster on larger DataFrames

df = pd.DataFrame({'a': [1,2,3] * 100000, 'b': [2,3,4] * 100000})

DataFrame created with 300,000 rows

%timeit df["A1"], df["A2"] = calculate(df['a'])
2.65 ms ± 92.4 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)

%timeit df["A1"], df["A2"] = zip(*df["a"].apply(calculate))
159 ms ± 5.24 ms per loop (mean ± std. dev. of 7 runs, 10 loops each)

60x faster than zip

In general, avoid using apply

Apply is generally not much faster than iterating over a Python list. Let's test the performance of a for-loop to do the same thing as above

%%timeit
A1, A2 = [], []
for val in df['a']:
    A1.append(val**2)
    A2.append(val**3)

df['A1'] = A1
df['A2'] = A2

298 ms ± 7.14 ms per loop (mean ± std. dev. of 7 runs, 1 loop each)

So this is twice as slow which isn't a terrible performance regression, but if we cythonize the above, we get much better performance. Assuming, you are using ipython:

%load_ext cython

%%cython
cpdef power(vals):
    A1, A2 = [], []
    cdef double val
    for val in vals:
        A1.append(val**2)
        A2.append(val**3)

    return A1, A2

%timeit df['A1'], df['A2'] = power(df['a'])
72.7 ms ± 2.16 ms per loop (mean ± std. dev. of 7 runs, 10 loops each)

Directly assigning without apply

You can get even greater speed improvements if you use the direct vectorized operations.

%timeit df['A1'], df['A2'] = df['a'] ** 2, df['a'] ** 3
5.13 ms ± 320 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)

This takes advantage of NumPy's extremely fast vectorized operations instead of our loops. We now have a 30x speedup over the original.

The simplest speed test with apply

The above example should clearly show how slow apply can be, but just so its extra clear let's look at the most basic example. Let's square a Series of 10 million numbers with and without apply

s = pd.Series(np.random.rand(10000000))

%timeit s.apply(calc)
3.3 s ± 57.4 ms per loop (mean ± std. dev. of 7 runs, 1 loop each)

Without apply is 50x faster

%timeit s ** 2
66 ms ± 2 ms per loop (mean ± std. dev. of 7 runs, 10 loops each)

Edit:

The oracle tag was not on the question when this answer was offered, and apparently it doesn't work with oracle, but it does work with at least postgres and mysql

No, just use the value directly:

begin
  if (select count(*) from table) > 0 then
     update table
  end if;
end;

Note there is no need for an "else".

Edited

You can simply do it all within the update statement (ie no if construct):

update table
set ...
where ...
and exists (select 'x' from table where ...)

That query is failing and returning false.

Put this after mysqli_query() to see what's going on.

if (!$check1_res) {
    printf("Error: %s\n", mysqli_error($con));
    exit();
}

I will use one example to explain how JNDI can be used to configure database without any application developer knowing username and password of the database.

1) We have configured the data source in JBoss server's standalone-full.xml. Additionally, we can configure pool details also.

 <datasource jta="false" jndi-name="java:/DEV.DS" pool-name="DEV" enabled="true" use-ccm="false">
                <connection-url>jdbc:oracle:thin:@<IP>:1521:DEV</connection-url>
                <driver-class>oracle.jdbc.OracleDriver</driver-class>
                <driver>oracle</driver>
                <security>
                    <user-name>usname</user-name>
                    <password>pass</password>
                    </security>
                    <security>

 <security-domain>encryptedSecurityDomain</security-domain>
                    </security>

                <validation>
                    <validate-on-match>false</validate-on-match>
                    <background-validation>false</background-validation>
                    <background-validation-millis>1</background-validation-millis>
                </validation>
                <statement>
                    <prepared-statement-cache-size>0</prepared-statement-cache-size>
                    <share-prepared-statements>false</share-prepared-statements>
                    <pool>
                        <min-pool-size>5</min-pool-size>
                        <max-pool-size>10</max-pool-size>
                    </pool>
                </statement>
            </datasource>

Now, this jndi-name and its associated datasource object will be available for our application.application.

2) We can retrieve this datasource object using JndiDataSourceLookup class.

Spring will instantiate the datasource bean, after we provide the jndi-name.

Now, we can change the pool size, user name or password as per our environment or requirement, but it will not impact the application.

Note : encryptedSecurityDomain, we need to configure it separately in JBoss server like

<security-domain name="encryptedSecurityDomain" cache-type="default">
                    <authentication>
                        <login-module code="org.picketbox.datasource.security.SecureIdentityLoginModule" flag="required">
                            <module-option name="username" value="<usernamefordb>"/>
                            <module-option name="password" value="894c8a6aegc8d028ce169c596d67afd0"/>
                        </login-module>
                    </authentication>
                </security-domain>

This is one of the use cases. Hope it clarifies.

The answers are outdated. You simply have to conda install pip and git. Then you can use pip normally:

1. Activate your conda environment source activate myenv

2. conda install git pip

3. pip install git+git://github.com/scrappy/scrappy@master

Yes, according to RFC 3696 apostrophes are valid as long as they come before the @ symbol.

This is how:

[November 2020 Update: This solution relies on being able to set document.domain. The ability to do that has now been deprecated, unfortunately.]

For sharing between subdomains of a given superdomain (e.g. example.com), there's a technique you can use in that situation. It can be applied to localStorage, IndexedDB, SharedWorker, BroadcastChannel, etc, all of which offer shared functionality between same-origin pages, but for some reason don't respect any modification to document.domain that would let them use the superdomain as their origin directly.

(1) Pick one "main" domain to for the data to belong to: i.e. either https://example.com or https://www.example.com will hold your localStorage data. Let's say you pick https://example.com.

(2) Use localStorage normally for that chosen domain's pages.

(3) On all https://www.example.com pages (the other domain), use javascript to set document.domain = "example.com";. Then also create a hidden <iframe>, and navigate it to some page on the chosen https://example.com domain (It doesn't matter what page, as long as you can insert a very little snippet of javascript on there. If you're creating the site, just make an empty page specifically for this purpose. If you're writing an extension or a Greasemonkey-style userscript and so don't have any control over pages on the example.com server, just pick the most lightweight page you can find and insert your script into it. Some kind of "not found" page would probably be fine).

(4) The script on the hidden iframe page need only (a) set document.domain = "example.com";, and (b) notify the parent window when this is done. After that, the parent window can access the iframe window and all its objects without restriction! So the minimal iframe page is something like:

<!doctype html>
<html>
<head>
  <script>
    document.domain = "example.com";
    window.parent.iframeReady();  // function defined & called on parent window
  </script>
</head>
<body></body>
</html>

If writing a userscript, you might not want to add externally-accessible functions such as iframeReady() to your unsafeWindow, so instead a better way to notify the main window userscript might be to use a custom event:

    window.parent.dispatchEvent(new CustomEvent("iframeReady"));

Which you'd detect by adding a listener for the custom "iframeReady" event to your main page's window.

(NOTE: You need to set document.domain = "example.com" even if the iframe's domain is already example.com: Assigning a value to document.domain implicitly sets the origin's port to null, and both ports must match for the iframe and its parent to be considered same-origin. See the note here: https://developer.mozilla.org/en-US/docs/Web/Security/Same-origin_policy#Changing_origin)

(5) Once the hidden iframe has informed its parent window that it's ready, script in the parent window can just use iframe.contentWindow.localStorage, iframe.contentWindow.indexedDB, iframe.contentWindow.BroadcastChannel, iframe.contentWindow.SharedWorker instead of window.localStorage, window.indexedDB, etc. ...and all these objects will be scoped to the chosen https://example.com origin - so they'll have the this same shared origin for all of your pages!

The most awkward part of this technique is that you have to wait for the iframe to load before proceeding. So you can't just blithely start using localStorage in your DOMContentLoaded handler, for example. Also you might want to add some error handling to detect if the hidden iframe fails to load correctly.

Obviously, you should also make sure the hidden iframe is not removed or navigated during the lifetime of your page... OTOH I don't know what the result of that would be, but very likely bad things would happen.

And, a caveat: setting/changing document.domain can be blocked using the Feature-Policy header, in which case this technique will not be usable as described.

However, there is a significantly more-complicated generalization of this technique, that can't be blocked by Feature-Policy, and that also allows entirely unrelated domains to share data, communications, and shared workers (i.e. not just subdomains off a common superdomain). @Mayank Jain already described it in their answer, namely:

The general idea is that, just as above, you create a hidden iframe to provide the correct origin for access; but instead of then just grabbing the iframe window's properties directly, you use script inside the iframe to do all of the work, and you communicate between the iframe and your main window only using postMessage() and addEventListener("message",...).

This works because postMessage() can be used even between different-origin windows. But it's also significantly more complicated because you have to pass everything through some kind of messaging infrastructure that you create between the iframe and the main window, rather than just using the localStorage, IndexedDB, etc. APIs directly in your main window's code.

Ctrl + Shift + C . Works great on .java, .xhtml, .properties and maybe on others but I only tested these ones. Can comment single or multiple lines.

I had this problem recently where apt install wget does not find anything. As it turns out apt update was never run.

apt update
apt install wget

After discussing this with a coworker we mused that apt update is likely not run in order to save both time and space in the docker image.

looks to me yum install glibc.i686 should have worked. Unless Peter was not root. He has the 64 bit glib installed, he is installing a 32 bit package that requires the 32 bit glib which is glib.i686 for intel processors.

Use IPython display to render PIL images in a notebook.

from PIL import Image               # to load images
from IPython.display import display # to display images

pil_im = Image.open('path/to/image.jpg')
display(pil_im)

The results of the execution time directly contradict the results of the Query Cost, but I'm having difficulty determining what "Query Cost" actually means.

Query cost is what optimizer thinks of how long your query will take (relative to total batch time).

The optimizer tries to choose the optimal query plan by looking at your query and statistics of your data, trying several execution plans and selecting the least costly of them.

Here you may read in more detail about how does it try to do this.

As you can see, this may differ significantly of what you actually get.

The only real query perfomance metric is, of course, how long does the query actually take.

One more approach would be to apply n() function which is counting the number of observations

library(dplyr)
library(magrittr)
data %>% 
  group_by(columnName) %>%
  summarise(Count = n())

You need to have access as well on the site that you will be iframing. i found the best solution here: https://gist.github.com/MateuszFlisikowski/91ff99551dcd90971377

yourotherdomain.html

<script type='text/javascript' src="js/jquery.min.js"></script>
<script type='text/javascript'>
  // Size the parent iFrame
  function iframeResize() {
    var height = $('body').outerHeight(); // IMPORTANT: If body's height is set to 100% with CSS this will not work.
    parent.postMessage("resize::"+height,"*");
  }

  $(document).ready(function() {
    // Resize iframe
    setInterval(iframeResize, 1000);
  });
</script>

your website with iframe

<iframe src='example.html' id='edh-iframe'></iframe>
<script type='text/javascript'>
  // Listen for messages sent from the iFrame
  var eventMethod = window.addEventListener ? "addEventListener" : "attachEvent";
  var eventer = window[eventMethod];
  var messageEvent = eventMethod == "attachEvent" ? "onmessage" : "message";

  eventer(messageEvent,function(e) {
    // If the message is a resize frame request
    if (e.data.indexOf('resize::') != -1) {
      var height = e.data.replace('resize::', '');
      document.getElementById('edh-iframe').style.height = height+'px';
    }
  } ,false);
</script>

WITH (NOLOCK) is the equivalent of using READ UNCOMMITED as a transaction isolation level. So, you stand the risk of reading an uncommitted row that is subsequently rolled back, i.e. data that never made it into the database. So, while it can prevent reads being deadlocked by other operations, it comes with a risk. In a banking application with high transaction rates, it's probably not going to be the right solution to whatever problem you're trying to solve with it IMHO.

Very Simple Solution.

1. Login with System admin
2. copy your mdf and ldf files in "C:\Program Files (x86)\Microsoft SQL Server\MSSQL11.MSSQLSERVER\MSSQL\DATA" Where all other data file recides.
3. Now attach from there it will work

If you are only looking for a refresh rate for the GOOGLEFINANCE function, keep in mind that data delays can be up to 20 minutes (per Google Finance Disclaimer).

Single-symbol refresh rate (using GoogleClock)

Here is a modified version of the refresh action, taking the data delay into consideration, to save on unproductive refresh cycles.

=GoogleClock(GOOGLEFINANCE(symbol,"datadelay"))

For example, with:

• SYMBOL: GOOG
• DATA DELAY: 15 (minutes)

then

=GoogleClock(GOOGLEFINANCE("GOOG","datadelay"))

Results in a dynamic data-based refresh rate of:

=GoogleClock(15)

Multi-symbol refresh rate (using GoogleClock)

If your sheet contains a number of rows of symbols, you could add a datadelay column for each symbol and use the lowest value, for example:

=GoogleClock(MIN(dataDelayValuesNamedRange))

Where dataDelayValuesNamedRange is the absolute reference or named reference of the range of cells that contain the data delay values for each symbol (assuming these values are different).

Without GoogleClock()

The GoogleClock() function was removed in 2014 and replaced with settings setup for refreshing sheets. At present, I have confirmed that replacement settings is only on available in Sheets from when accessed from a desktop browser, not the mobile app (I'm using Google's mobile Sheets app updated 2016-03-14).

(This part of the answer is based on, and portions copied from, Google Docs Help)

To change how often "some" Google Sheets functions update:

1. Open a spreadsheet. Click File > Spreadsheet settings.
2. In the RECALCULATION section, choose a setting from the drop-down menu.
3. Setting options are:
   • On change
   • On change and every minute
   • On change and every hour
4. Click SAVE SETTINGS.

NOTE External data functions recalculate at the following intervals:

• ImportRange: 30 minutes
• ImportHtml, ImportFeed, ImportData, ImportXml: 1 hour
• GoogleFinance: 2 minutes

The references in earlier sections to the display and use of the datadelay attribute still apply, as well as the concepts for more efficient coding of sheets.

On a positive note, the new refresh option continues to be refreshed by Google servers regardless of whether you have the sheet loaded or not. That's a positive for shared sheets for sure; even more so for Google Apps Scripts (GAS), where GAS is used in workflow code or referenced data is used as a trigger for an event.

[*] in my understanding so far (I am currently testing this)

Empty array for empty collections and null for everything else.

this will be slow, but if it is a one time thing, try...

select * from parameters where name like '%'+char(13)+'%' or name like '%'+char(10)+'%'

Note that the ANSI SQL string concatenation operator is "||", so it may need to be:

select * from parameters where name like '%' || char(13) || '%' or name like '%' || char(10) || '%'

Even when you asked finally for the opposite, to reform 0s and 1s into Trues and Falses, however, I post an answer about how to transform falses and trues into ones and zeros (1s and 0s), for a whole dataframe, in a single line.

Example given

df <- structure(list(p1_1 = c(TRUE, FALSE, FALSE, NA, TRUE, FALSE, 
                NA), p1_2 = c(FALSE, TRUE, FALSE, NA, FALSE, NA, 
                TRUE), p1_3 = c(TRUE, 
                TRUE, FALSE, NA, NA, FALSE, TRUE), p1_4 = c(FALSE, NA, 
                FALSE,  FALSE, TRUE, FALSE, NA), p1_5 = c(TRUE, NA, 
                FALSE, TRUE, FALSE, NA, TRUE), p1_6 = c(TRUE, NA, 
                FALSE, TRUE, FALSE, NA, TRUE), p1_7 = c(TRUE, NA, 
                FALSE, TRUE, NA, FALSE, TRUE), p1_8 = c(FALSE, 
                FALSE, NA, FALSE, TRUE, FALSE, NA), p1_9 = c(TRUE, 
                FALSE,  NA, FALSE, FALSE, NA, TRUE), p1_10 = c(TRUE, 
                FALSE, NA, FALSE, FALSE, NA, TRUE), p1_11 = c(FALSE, 
                FALSE, NA, FALSE, NA, FALSE, TRUE)), .Names = 
                c("p1_1", "p1_2", "p1_3", "p1_4", "p1_5", "p1_6", 
                "p1_7", "p1_8", "p1_9", "p1_10", "p1_11"), row.names = 
                 c(NA, -7L), class = "data.frame")

   p1_1  p1_2  p1_3  p1_4  p1_5  p1_6  p1_7  p1_8  p1_9 p1_10 p1_11
1  TRUE FALSE  TRUE FALSE  TRUE  TRUE  TRUE FALSE  TRUE  TRUE FALSE
2 FALSE  TRUE  TRUE    NA    NA    NA    NA FALSE FALSE FALSE FALSE
3 FALSE FALSE FALSE FALSE FALSE FALSE FALSE    NA    NA    NA    NA
4    NA    NA    NA FALSE  TRUE  TRUE  TRUE FALSE FALSE FALSE FALSE
5  TRUE FALSE    NA  TRUE FALSE FALSE    NA  TRUE FALSE FALSE    NA
6 FALSE    NA FALSE FALSE    NA    NA FALSE FALSE    NA    NA FALSE
7    NA  TRUE  TRUE    NA  TRUE  TRUE  TRUE    NA  TRUE  TRUE  TRUE

Then by running that: df * 1 all Falses and Trues are trasnformed into 1s and 0s. At least, this was happen in the R version that I have (R version 3.4.4 (2018-03-15) ).

> df*1
  p1_1 p1_2 p1_3 p1_4 p1_5 p1_6 p1_7 p1_8 p1_9 p1_10 p1_11
1    1    0    1    0    1    1    1    0    1     1     0
2    0    1    1   NA   NA   NA   NA    0    0     0     0
3    0    0    0    0    0    0    0   NA   NA    NA    NA
4   NA   NA   NA    0    1    1    1    0    0     0     0
5    1    0   NA    1    0    0   NA    1    0     0    NA
6    0   NA    0    0   NA   NA    0    0   NA    NA     0
7   NA    1    1   NA    1    1    1   NA    1     1     1

I do not know if it a total "safe" command, under all different conditions / dfs.

The first problem with your script is that you have to put a space after the [.
Type type [ to see what is really happening. It should tell you that [ is an alias to test command, so [ ] in bash is not some special syntax for conditionals, it is just a command on its own. What you should prefer in bash is [[ ]]. This common pitfall is greatly explained here and here.

Another problem is that you didn't quote "$f" which might become a problem later. This is explained here

You can use arithmetic expressions in if, so you don't have to use [ ] or [[ ]] at all in some cases. More info here

Also there's no need to use \n in every echo, because echo places newlines by default. If you want TWO newlines to appear, then use echo -e 'start\n' or echo $'start\n' . This $'' syntax is explained here

To make it completely perfect you should place -- before arbitrary filenames, otherwise rm might treat it as a parameter if the file name starts with dashes. This is explained here.

So here's your script:

#!/bin/bash
echo "start"
for f in *.jpg
do
    fname="${f##*/}"
    echo "fname is $fname"
    if (( fname % 2 == 1 )); then
        echo "removing $fname"
        rm -- "$f"
    fi
done

For ex .. add class:

btn-lg - LARGE

btn-sm - SMALL

btn-xs - Very small

<button type=button class="btn btn-default btn-lg">
<span class="glyphicon glyphicon-star" aria-hidden=true></span> Star
</button> 

<button type=button class="btn btn-default">
<span class="glyphicon glyphicon-star" aria-hidden=true></span>Star
</button>

 <button type=button class="btn btn-default btn-sm">
<span class="glyphicon glyphicon-star" aria-hidden=true></span> Star
</button> 

<button type=button class="btn btn-default btn-xs">
<span class="glyphicon glyphicon-star" aria-hidden=true></span> Star
</button>

Type switches can also be used with reflection stuff:

var str = "hello!"
var obj = reflect.ValueOf(&str)

switch obj.Elem().Interface().(type) {
case string:
    log.Println("obj contains a pointer to a string")
default:
    log.Println("obj contains something else")
}

I am also having the same problem. I have a json which is to be converted to ArrayList.

Account looks like this.

Account{
  Person p ;
  Related r ;

}

Person{
    String Name ;
    Address a ;
}

All of the above classes have been annotated properly. I have tried TypeReference>() {} but is not working.

It gives me Arraylist but ArrayList has a linkedHashMap which contains some more linked hashmaps containing final values.

My code is as Follows:

public T unmarshal(String responseXML,String c)
{
    ObjectMapper mapper = new ObjectMapper();

    AnnotationIntrospector introspector = new JacksonAnnotationIntrospector();

    mapper.getDeserializationConfig().withAnnotationIntrospector(introspector);

    mapper.getSerializationConfig().withAnnotationIntrospector(introspector);
    try
    {
      this.targetclass = (T) mapper.readValue(responseXML,  new TypeReference<ArrayList<T>>() {});
    }
    catch (JsonParseException e)
    {
      e.printStackTrace();
    }
    catch (JsonMappingException e) {
      e.printStackTrace();
    } catch (IOException e) {
      e.printStackTrace();
    }

    return this.targetclass;
}

I finally solved the problem. I am able to convert the List in Json String directly to ArrayList as follows:

JsonMarshallerUnmarshaller<T>{

     T targetClass ;

     public ArrayList<T> unmarshal(String jsonString)
     {
        ObjectMapper mapper = new ObjectMapper();

        AnnotationIntrospector introspector = new JacksonAnnotationIntrospector();

        mapper.getDeserializationConfig().withAnnotationIntrospector(introspector);

        mapper.getSerializationConfig().withAnnotationIntrospector(introspector);
        JavaType type = mapper.getTypeFactory().
                    constructCollectionType(ArrayList.class, targetclass.getClass()) ;
        try
        {
        Class c1 = this.targetclass.getClass() ;
        Class c2 = this.targetclass1.getClass() ;
            ArrayList<T> temp = (ArrayList<T>) mapper.readValue(jsonString,  type);
        return temp ;
        }
       catch (JsonParseException e)
       {
        e.printStackTrace();
       }
       catch (JsonMappingException e) {
           e.printStackTrace();
       } catch (IOException e) {
          e.printStackTrace();
       }

     return null ;
    }  

}

Differently from Dan, I consider his answer quite elegant... but unfortunately it is also very very inefficient. So, since the question mentioned "a large csv file", let me suggest to try in a shell Dan's solution:

time python -c "import pandas as pd;
df = pd.DataFrame(['a b c']*100000, columns=['col']);
print df['col'].apply(lambda x : pd.Series(x.split(' '))).head()"

... compared to this alternative:

time python -c "import pandas as pd;
from scipy import array, concatenate;
df = pd.DataFrame(['a b c']*100000, columns=['col']);
print pd.DataFrame(concatenate(df['col'].apply( lambda x : [x.split(' ')]))).head()"

... and this:

time python -c "import pandas as pd;
df = pd.DataFrame(['a b c']*100000, columns=['col']);
print pd.DataFrame(dict(zip(range(3), [df['col'].apply(lambda x : x.split(' ')[i]) for i in range(3)]))).head()"

The second simply refrains from allocating 100 000 Series, and this is enough to make it around 10 times faster. But the third solution, which somewhat ironically wastes a lot of calls to str.split() (it is called once per column per row, so three times more than for the others two solutions), is around 40 times faster than the first, because it even avoids to instance the 100 000 lists. And yes, it is certainly a little ugly...

EDIT: this answer suggests how to use "to_list()" and to avoid the need for a lambda. The result is something like

time python -c "import pandas as pd;
df = pd.DataFrame(['a b c']*100000, columns=['col']);
print pd.DataFrame(df.col.str.split().tolist()).head()"

which is even more efficient than the third solution, and certainly much more elegant.

EDIT: the even simpler

time python -c "import pandas as pd;
df = pd.DataFrame(['a b c']*100000, columns=['col']);
print pd.DataFrame(list(df.col.str.split())).head()"

works too, and is almost as efficient.

EDIT: even simpler! And handles NaNs (but less efficient):

time python -c "import pandas as pd;
df = pd.DataFrame(['a b c']*100000, columns=['col']);
print df.col.str.split(expand=True).head()"

Add below line to your .gitignore

*/node_modules/*

This will ignore all node_modules in your current directory as well as subdirectory.

1. If you're in a heavily concurrent environment, then pure functional programming is useful. The lack of mutable state makes concurrency almost trivial. See Erlang.

2. In a multiparadigm language, you may want to model some things functionally if the existence of mutable state is must an implementation detail, and thus FP is a good model for the problem domain. For example, see list comprehensions in Python or std.range in the D programming language. These are inspired by functional programming.

Assuming that your original dataset is similar to the one you created (i.e. with NA as character. You could specify na.strings while reading the data using read.table. But, I guess NAs would be detected automatically.

The price column is factor which needs to be converted to numeric class. When you use as.numeric, all the non-numeric elements (i.e. "NA", FALSE) gets coerced to NA) with a warning.

library(dplyr)
df %>%
     mutate(price=as.numeric(as.character(price))) %>%  
     group_by(company, year, product) %>%
     summarise(total.count=n(), 
               count=sum(is.na(price)), 
               avg.price=mean(price,na.rm=TRUE),
               max.price=max(price, na.rm=TRUE))

data

I am using the same dataset (except the ... row) that was showed.

df = tbl_df(data.frame(company=c("Acme", "Meca", "Emca", "Acme", "Meca","Emca"),
 year=c("2011", "2010", "2009", "2011", "2010", "2013"), product=c("Wrench", "Hammer",
 "Sonic Screwdriver", "Fairy Dust", "Kindness", "Helping Hand"), price=c("5.67",
 "7.12", "12.99", "10.99", "NA",FALSE)))

There is a way to get count of runes without any packages by converting string to []rune as len([]rune(YOUR_STRING)):

package main

import "fmt"

func main() {
    russian := "??????? ? ??????"
    english := "Sputnik & pogrom"

    fmt.Println("count of bytes:",
        len(russian),
        len(english))

    fmt.Println("count of runes:",
        len([]rune(russian)),
        len([]rune(english)))

}

count of bytes 30 16

count of runes 16 16

This is my preferred version using a class based view. Simply subclass the basic View and override the get()-method.

import json

class MyJsonView(View):

    def get(self, *args, **kwargs):
        resp = {'my_key': 'my value',}
        return HttpResponse(json.dumps(resp), mimetype="application/json" )

HH used 24 hour format while hh used for 12 format

I'm using:

public class Person
{
    public string FirstName { get; set; }
    public string LastName { get; set; }
}

class Program
{
    static void Main(string[] args)
    {
        const string DEFAULT_NAMESPACE = "http://www.something.org/schema";
        var serializer = new XmlSerializer(typeof(Person), DEFAULT_NAMESPACE);
        var namespaces = new XmlSerializerNamespaces();
        namespaces.Add("", DEFAULT_NAMESPACE);

        using (var stream = new MemoryStream())
        {
            var someone = new Person
            {
                FirstName = "Donald",
                LastName = "Duck"
            };
            serializer.Serialize(stream, someone, namespaces);
            stream.Position = 0;
            using (var reader = new StreamReader(stream))
            {
                Console.WriteLine(reader.ReadToEnd());
            }
        }
    }
}

To get the following XML:

<?xml version="1.0"?>
<Person xmlns="http://www.something.org/schema">
  <FirstName>Donald</FirstName>
  <LastName>Duck</LastName>
</Person>

If you don't want the namespace, just set DEFAULT_NAMESPACE to "".

This is how I would do it (assuming I understand the question)

SELECT * FROM pieces ORDER BY price ASC LIMIT 1

If you are trying to select multiple rows where each of them may have the same price (which is the minimum) then @JohnWoo's answer should suffice.

Basically here we are just ordering the results by the price in ASCending order (increasing) and taking the first row of the result.

Anytime you have a question about a particular function in PHP, the easiest way to get quick answers is by visiting php.net, which has great documentation on all of the language's capabilities.

Looking up a function is easy, just visit http://php.net/<function name> and it will forward you to the appropriate place. For the date function, we'll visit http://php.net/date.

We immediately learn a couple things about this function by examining its signature:

string date ( string $format [, int $timestamp = time() ] )

First, it returns a string. That's what the first string in the above code means. Secondly, the first parameter is expected to be a string containing the format. There is an optional second parameter for passing in your own timestamp (to construct strings from some time other than now).

date("d-m-Y") // produces something like 03-12-2012

In this code, d represents the day of the month (with a leading 0 is necessary). m represents the month, again with a leading zero if necessary. And Y represents the full 4-digit year. All of these are documented in the aforementioned link.

To satisfy your request of getting the hours, minutes, and seconds, we need to give a quick look at the documentation to see which characters represents those particular units of time. When we do that, we find the following:

h   12-hour format of an hour with leading zeros    01 through 12
i   Minutes with leading zeros                      00 to 59
s   Seconds, with leading zeros                     00 through 59

With this in mind, we can no create a new format string:

date("d-m-Y h:i:s"); // produces something like 03-12-2012 03:29:13

Hope this is helpful, and I hope you find the documentation has benefiting to your development as I have to mine.

Excerpt from my Blog-Note-to-myself:

Now you can import a dump file e.g. if you are migrating between machines / subversion versions. e.g. if I had created a dump file from the source repository and load it into the new repository as shown below.

Commands for Unix-like systems (from terminal):

svnadmin dump /path/to/your/old/repo > backup.dump
svnadmin load /path/to/your/new/repo < backup.dump.dmp

Commands for Microsoft Windows systems (from cmd shell):

svnadmin dump C:\path\to\your\old\repo > backup.dump
svnadmin load C:\path\to\your\old\repo < backup.dump

All previous answers are correct, if you are looking for random characters of various types (i.e. alphanumeric and special characters) then here is an script that I created to demonstrate various types of creating random functions, it has three functions one for numbers, alpha- characters and special characters. The script simply generates passwords and is just an example to demonstrate various ways of generating random characters.

import string
import random
import sys

#make sure it's 3.7 or above
print(sys.version)

def create_str(str_length):
    return random.sample(string.ascii_letters, str_length)

def create_num(num_length):
    digits = []
    for i in range(num_length):
        digits.append(str(random.randint(1, 100)))

    return digits

def create_special_chars(special_length):
    stringSpecial = []
    for i in range(special_length):
        stringSpecial.append(random.choice('!$%&()*+,-.:;<=>?@[]^_`{|}~'))

    return stringSpecial

print("how many characters would you like to use ? (DO NOT USE LESS THAN 8)")
str_cnt = input()
print("how many digits would you like to use ? (DO NOT USE LESS THAN 2)")
num_cnt = input()
print("how many special characters would you like to use ? (DO NOT USE LESS THAN 1)")
s_chars_cnt = input()
password_values = create_str(int(str_cnt)) +create_num(int(num_cnt)) + create_special_chars(int(s_chars_cnt))

#shuffle/mix the values
random.shuffle(password_values)

print("generated password is: ")
print(''.join(password_values))

Result:

SELECT (to_date('02-JAN-2013') - to_date('02-JAN-2012')) days_between
FROM dual
/

find triggers on table:

select so.name, text
from sysobjects so, syscomments sc
where type = 'TR'
and so.id = sc.id
and text like '%TableName%'

and you can find store procedure which has reference of table:

SELECT Name
FROM sys.procedures
WHERE OBJECT_DEFINITION(OBJECT_ID) LIKE '%yourtablename%'

If the first segment doesn't start with / it is a relative route. router.navigate needs a relativeTo parameter for relative navigation

Either you make the route absolute:

this.router.navigate(['/foo-content', 'bar-contents', 'baz-content', 'page'], this.params.queryParams)

or you pass relativeTo

this.router.navigate(['../foo-content', 'bar-contents', 'baz-content', 'page'], {queryParams: this.params.queryParams, relativeTo: this.currentActivatedRoute})

In my case I have used a tab size(7") emulator to test the application.But It gave me "Failed to install xxxxx.apk on device 'emulator-5554! " and launch cancelled.

The only worked solution to me was set the emulator ram size bit high(1512Mb) and VM Heap size to 36.

After that It worked like charm.

Thank You.

TCO (Tail Call Optimization) is the process by which a smart compiler can make a call to a function and take no additional stack space. The only situation in which this happens is if the last instruction executed in a function f is a call to a function g (Note: g can be f). The key here is that f no longer needs stack space - it simply calls g and then returns whatever g would return. In this case the optimization can be made that g just runs and returns whatever value it would have to the thing that called f.

This optimization can make recursive calls take constant stack space, rather than explode.

Example: this factorial function is not TCOptimizable:

def fact(n):
    if n == 0:
        return 1
    return n * fact(n-1)

This function does things besides call another function in its return statement.

This below function is TCOptimizable:

def fact_h(n, acc):
    if n == 0:
        return acc
    return fact_h(n-1, acc*n)

def fact(n):
    return fact_h(n, 1)

This is because the last thing to happen in any of these functions is to call another function.

With my Android 5 tablet, every time I attempt to use adb, to install a signed release apk, I get the [INSTALL_FAILED_ALREADY_EXISTS] error.

I have to uninstall the debug package first. But, I cannot uninstall using the device's Application Manager!

If do uninstall the debug version with the Application Manager, then I have to re-run the debug build variant from Android Studio, then uninstall it using adb uninstall com.example.mypackagename

Finally, I can use adb install myApp.apk to install the signed release apk.

You'll need to couple the event listener to $rootScope in Angular 1.x, but you should probably future proof your code a bit by not storing the value of the previous location on $rootScope. A better place to store the value would be a service:

var app = angular.module('myApp', [])
.service('locationHistoryService', function(){
    return {
        previousLocation: null,

        store: function(location){
            this.previousLocation = location;
        },

        get: function(){
            return this.previousLocation;
        }
})
.run(['$rootScope', 'locationHistoryService', function($location, locationHistoryService){
    $rootScope.$on('$locationChangeSuccess', function(e, newLocation, oldLocation){
        locationHistoryService.store(oldLocation);
    });
}]);

I added the spring folder to the build path and, after clean&build, it worked.

Sometimes, casting an Int to a Double is not a viable solution. At some magnitudes there is a loss of precision in this conversion. For example, the following code does not return what you might intuitively expect.

Double(Int.max - 1) < Double(Int.max) // false!

If you need precision at high magnitudes and don't need to worry about negative exponents — which can't be generally solved with integers anyway — then this implementation of the tail-recursive exponentiation-by-squaring algorithm is your best bet. According to this SO answer, this is "the standard method for doing modular exponentiation for huge numbers in asymmetric cryptography."

// using Swift 5.0
func pow<T: BinaryInteger>(_ base: T, _ power: T) -> T {
    func expBySq(_ y: T, _ x: T, _ n: T) -> T {
        precondition(n >= 0)
        if n == 0 {
            return y
        } else if n == 1 {
            return y * x
        } else if n.isMultiple(of: 2) {
            return expBySq(y, x * x, n / 2)
        } else { // n is odd
            return expBySq(y * x, x * x, (n - 1) / 2)
        }
    }

    return expBySq(1, base, power) 
}

Note: in this example I've used a generic T: BinaryInteger. This is so you can use Int or UInt or any other integer-like type.

Create a new directory layout-land, then create xml file with same name in layout-land as it was layout directory and align there your content for Landscape mode.

Note that id of content in both xml is same.

In case you have to deal with the arguably unfriendly logs client (CloudWatch Logs put-log-events), this is what I had to do to properly catch Boto3 client exceptions:

try:
    ### Boto3 client code here...

except boto_exceptions.ClientError as error:
    Log.warning("Catched client error code %s",
                error.response['Error']['Code'])

    if error.response['Error']['Code'] in ["DataAlreadyAcceptedException",
                                           "InvalidSequenceTokenException"]:
        Log.debug(
            "Fetching sequence_token from boto error response['Error']['Message'] %s",
            error.response["Error"]["Message"])
        # NOTE: apparently there's no sequenceToken attribute in the response so we have
        # to parse response["Error"]["Message"] string
        sequence_token = error.response["Error"]["Message"].split(":")[-1].strip(" ")
        Log.debug("Setting sequence_token to %s", sequence_token)

This works both at first attempt (with empty LogStream) and subsequent ones.

Thank you to everyone that answered. Since this was closed for a long time I couldn't provide much feedback, but I did eventually fix my problem. I tried many of these other solutions and they didn't fix my issue, but I'm sure they help when the root cause is different.

My Solution

I solved this problem by turning off the IIS and .Net Framework features within Windows 7 and then turning them back on. It seems like this re-installation is what fixed my issue. I still don't know what caused the problem, but at least one other developer on my team had the same issue.

Solution:

mongoexport --db test --collection traffic --out traffic.json<br><br>

Where:
database -> mock-server
collection name -> api_defs
output file name -> childChoreRequest.json

The rule is as following :

A B 

B as a descendant of A

A > B 

B as a child of A

So

div.dropdown *

and not

div.dropdown > *

There are two ways of closing an alert dialog.

Option 1:

AlertDialog#create().dismiss();

Option 2:

The DialogInterface#dismiss();

Out of the box, the framework calls DialogInterface#dismiss(); when you define event listeners for the buttons:

1. AlertDialog#setNegativeButton();
2. AlertDialog#setPositiveButton();
3. AlertDialog#setNeutralButton();

for the Alert dialog.

To change the background color and not the tint the following piece of code will work:

[self.navigationController.navigationBar setBarTintColor:[UIColor greenColor]];
[self.navigationController.navigationBar setTranslucent:NO];

Use the Maven debug option, ie mvn -X :

If anyone has similar issue of having a phone with a cracked screen and has a need to access adb:

1. Root your phone (mine was already rooted, so I was blessed at least with that).

If you forgot to enable developers mode and your adb isn't running, then do the following:

1. Reboot your phone into recovery.
2. Connect the phone with a cable.
3. Open terminal.
4. If you type adb devices you should see the device in the list.

5. If so, type:

   adb shell mount /system
   abd shell
   
   echo "persist.service.adb.enable=1" >> default.prop 
   echo "persist.service.debuggable=1" >> default.prop
   echo "persist.sys.usb.config=mtp,adb" >> default.prop
   echo "persist.service.adb.enable=1" >> /system/build.prop 
   echo "persist.service.debuggable=1" >> /system/build.prop
   echo "persist.sys.usb.config=mtp,adb" >> /system/build.prop
   

Now if you are going to reboot into your phone android will tell you "oh your adb is working but please tap on this OK button, so we can trust your PC". And obviously if we can't tap on the phone stay in the recovery mode and do the following (assuming you are not in the adb shell mode, if so first type exit):

cd ~/.android
adb push adbkey.pub /data/misc/adb/adb_keys

6. Hurray, it all should be hunky-dory now! Just reboot the phone and you should be able to access adb when the phone is running:

   adb shell reboot

P.S. Was using OS X and Moto X Style that's with the cracked screen.

Return true if the input year is a leap year

Basic modern day code:

  If year mod 4 = 0, then leap year
  if year mod 100 then normal year
  if year mod 400 then leap year
  else normal year

Todays rule started 1582 AD Julian calendar rule with every 4th year started 46BC but is not coherent before 10 AD as declared by Cesar. They did however add some leap years every 3rd year now and then in the years before: Leap years were therefore 45 BC, 42 BC, 39 BC, 36 BC, 33 BC, 30 BC, 27 BC, 24 BC, 21 BC, 18 BC, 15 BC, 12 BC, 9 BC, 8 AD, 12 AD Before year 45BC leap year was not added.

The year 0 do not exist as it is ...2BC 1BC 1AD 2AD... for some calculation this can be an issue.

function isLeapYear(year: Integer): Boolean;
begin
  result := false;
  if year > 1582 then // Todays calendar rule was started in year 1582 
    result := ((year mod 4 = 0) and (not(year mod 100 = 0))) or (year mod 400 = 0)
  else if year > 10 then // Between year 10 and year 1582 every 4th year was a leap year 
    result := year mod 4 = 0
  else //Between year -45 and year 10 only certain years was leap year, every 3rd year but the entire time
    case year of
      -45, -42, -39, -36, -33, -30, -27, -24, -21, -18, -15, -12, -9:
        result := true;
    end;
end;

?. bad way: change delimiter

sed 's/xxx/'"$PWD"'/'
sed 's:xxx:'"$PWD"':'
sed 's@xxx@'"$PWD"'@'

maybe those not the final answer,

you can not known what character will occur in $PWD, / : OR @.

the good way is replace(escape) the special character in $PWD.

?. good way: escape delimiter

for example: try to replace URL as $url (has : / in content)

x.com:80/aa/bb/aa.js

in string $tmp

<a href="URL">URL</a>

A. use / as delimiter

escape / as \/ in var (before use in sed expression)

echo ${url//\//\\/}
x.com:80\/aa\/bb\/aa.js   #escape fine

echo ${url//\//\/}
x.com:80/aa/bb/aa.js      #escape not success

echo "${url//\//\/}"
x.com:80\/aa\/bb\/aa.js   #escape fine, notice `"`

echo $tmp | sed "s/URL/${url//\//\\/}/"
<a href="x.com:80/aa/bb/aa.js">URL</a>

echo $tmp | sed "s/URL/${url//\//\/}/"
<a href="x.com:80/aa/bb/aa.js">URL</a>

OR

B. use : as delimiter (more readable than /)

escape : as \: in var (before use in sed expression)

echo ${url//:/\:}
x.com:80/aa/bb/aa.js     #escape not success

echo "${url//:/\:}"
x.com\:80/aa/bb/aa.js    #escape fine, notice `"`

echo $tmp | sed "s:URL:${url//:/\:}:g"
<a href="x.com:80/aa/bb/aa.js">x.com:80/aa/bb/aa.js</a>

Your regex should work 'as-is'. Assuming that it is doing what you want it to.

wordA(\s*)wordB(?! wordc)

This means match wordA followed by 0 or more spaces followed by wordB, but do not match if followed by wordc. Note the single space between ?! and wordc which means that wordA wordB wordc will not match, but wordA wordB wordc will.

Here are some example matches and the associated replacement output:

Note that all matches are replaced no matter how many spaces. There are a couple of other points: -

• (?! wordc) is a negative lookahead, so you wont match lines wordA wordB wordc which is assume is intended (and is why the last line is not matched). Currently you are relying on the space after ?! to match the whitespace. You may want to be more precise and use (?!\swordc). If you want to match against more than one space before wordc you can use (?!\s*wordc) for 0 or more spaces or (?!\s*+wordc) for 1 or more spaces depending on what your intention is. Of course, if you do want to match lines with wordc after wordB then you shouldn't use a negative lookahead.

• * will match 0 or more spaces so it will match wordAwordB. You may want to consider + if you want at least one space.

• (\s*) - the brackets indicate a capturing group. Are you capturing the whitespace to a group for a reason? If not you could just remove the brackets, i.e. just use \s.

Update based on comment

Hello the problem is not the expression but the HTML out put   that are not considered as whitespace. it's a Joomla website.

Preserving your original regex you can use:

wordA((?:\s| )*)wordB(?!(?:\s| )wordc)

The only difference is that not the regex matches whitespace OR  . I replaced wordc with \swordc since that is more explicit. Note as I have already pointed out that the negative lookahead ?! will not match when wordB is followed by a single whitespace and wordc. If you want to match multiple whitespaces then see my comments above. I also preserved the capture group around the whitespace, if you don't want this then remove the brackets as already described above.

Example matches:

Also try thistr:hover td {color: aqua;} `

mod_deflate requires fewer resources on your server, although you may pay a small penalty in terms of the amount of compression.

If you are serving many small files, I'd recommend benchmarking and load testing your compressed and uncompressed solutions - you may find some cases where enabling compression will not result in savings.

You may use the == operator to compare unicode objects for equality.

>>> s1 = u'Hello'
>>> s2 = unicode("Hello")
>>> type(s1), type(s2)
(<type 'unicode'>, <type 'unicode'>)
>>> s1==s2
True
>>> 
>>> s3='Hello'.decode('utf-8')
>>> type(s3)
<type 'unicode'>
>>> s1==s3
True
>>> 

But, your error message indicates that you aren't comparing unicode objects. You are probably comparing a unicode object to a str object, like so:

>>> u'Hello' == 'Hello'
True
>>> u'Hello' == '\x81\x01'
__main__:1: UnicodeWarning: Unicode equal comparison failed to convert both arguments to Unicode - interpreting them as being unequal
False

See how I have attempted to compare a unicode object against a string which does not represent a valid UTF8 encoding.

Your program, I suppose, is comparing unicode objects with str objects, and the contents of a str object is not a valid UTF8 encoding. This seems likely the result of you (the programmer) not knowing which variable holds unicide, which variable holds UTF8 and which variable holds the bytes read in from a file.

I recommend http://nedbatchelder.com/text/unipain.html, especially the advice to create a "Unicode Sandwich."

Use the @ViewChildren decorator combined with QueryList. Both of these are from "@angular/core"

@ViewChildren(CustomComponent) customComponentChildren: QueryList<CustomComponent>;

Doing something with each child looks like: this.customComponentChildren.forEach((child) => { child.stuff = 'y' })

There is further documentation to be had at angular.io, specifically: https://angular.io/docs/ts/latest/cookbook/component-communication.html#!#sts=Parent%20calls%20a%20ViewChild

simply use: date("Y-m-d H:i:s") this will give you your date and time like '2020-08-22 12:20:30' this . add date_default_timezone_set("your time zone") before date() function to get the time date of your area/zone. here you can find you time zone

You got the first part right:

Yes mapStateToProps has the Store state as an argument/param (provided by react-redux::connect) and its used to link the component with certain part of the store state.

By linking I mean the object returned by mapStateToProps will be provided at construction time as props and any subsequent change will be available through componentWillReceiveProps.

If you know the Observer design pattern it's exactly that or small variation of it.

An example would help make things clearer:

import React, {
    Component,
} from 'react-native';

class ItemsContainer extends Component {
    constructor(props) {
        super(props);

        this.state = {
            items: props.items, //provided by connect@mapStateToProps
            filteredItems: this.filterItems(props.items, props.filters),
        };
    }

    componentWillReceiveProps(nextProps) {
        this.setState({
            filteredItems: this.filterItems(this.state.items, nextProps.filters),
        });
    }

    filterItems = (items, filters) => { /* return filtered list */ }

    render() {
        return (
            <View>
                // display the filtered items
            </View>
        );
    }
}

module.exports = connect(
    //mapStateToProps,
    (state) => ({
        items: state.App.Items.List,
        filters: state.App.Items.Filters,
        //the State.App & state.App.Items.List/Filters are reducers used as an example.
    })
    // mapDispatchToProps,  that's another subject
)(ItemsContainer);

There can be another react component called itemsFilters that handle the display and persisting the filter state into Redux Store state, the Demo component is "listening" or "subscribed" to Redux Store state filters so whenever filters store state changes (with the help of filtersComponent) react-redux detect that there was a change and notify or "publish" all the listening/subscribed components by sending the changes to their componentWillReceiveProps which in this example will trigger a refilter of the items and refresh the display due to the fact that react state has changed.

Let me know if the example is confusing or not clear enough to provide a better explanation.

As for: This means that the state as consumed by your target component can have a wildly different structure from the state as it is stored on your store.

I didn't get the question, but just know that the react state (this.setState) is totally different from the Redux Store state!

The react state is used to handle the redraw and behavior of the react component. The react state is contained to the component exclusively.

The Redux Store state is a combination of Redux reducers states, each is responsible of managing a small portion app logic. Those reducers attributes can be accessed with the help of react-redux::connect@mapStateToProps by any component! Which make the Redux store state accessible app wide while component state is exclusive to itself.

You can use fiddler as webdebugger http://www.telerik.com/fiddler/web-debugging

Fiddler is a debugging tool from telerik software, which helps you to intercept every request that is initiated from your machine.

So what you need to do is replace th:field with th:name and add th:value, th:value will have the value of the variable you're passing across.

<div class="col-auto">
        <input type="text" th:value="${client.name}" th:name="clientName" 
        class="form control">
</div>

You can dump a whole database in one go with mysqldump's --tab option. You supply a directory path and it creates one .sql file with the CREATE TABLE DROP IF EXISTS syntax and a .txt file with the contents, tab separated. To create comma separated files you could use the following:

mysqldump --password  --fields-optionally-enclosed-by='"' --fields-terminated-by=',' --tab /tmp/path_to_dump/ database_name

That path needs to be writable by both the mysql user and the user running the command, so for simplicity I recommend chmod 777 /tmp/path_to_dump/ first.

The nohup command is a signal masking utility and catches the hangup signal. Where as ampersand doesn’t catch the hang up signals. The shell will terminate the sub command with the hang up signal when running a command using & and exiting the shell. This can be prevented by using nohup, as it catches the signal. Nohup command accept hang up signal which can be sent to a process by the kernel and block them. Nohup command is helpful in when a user wants to start long running application log out or close the window in which the process was initiated. Either of these actions normally prompts the kernel to hang up on the application, but a nohup wrapper will allow the process to continue. Using the ampersand will run the command in a child process and this child of the current bash session. When you exit the session, all of the child processes of that process will be killed. The ampersand relates to job control for the active shell. This is useful for running a process in a session in the background.

In SQL Plus:

VAR rc REFCURSOR
EXEC gokul_proc(1,'GOKUL', :rc);
print rc

String to yyyy-MM-dd date format: Example:

TxtCalStDate.Text = Convert.ToDateTime(objItem["StartDate"]).ToString("yyyy/MM/dd");   

I like to use this mapping:

:nnoremap yp Yp

because it makes it consistent to use alongside the native YP command.

In 2020, iOS13, xCode 11.3. What is working for Objective-C is:

It's working for me, i hope the same to you! :D

Bootstrap is an open-source Javascript framework developed by the team at Twitter. It is a combination of HTML, CSS, and Javascript code designed to help build user interface components. Bootstrap was also programmed to support both HTML5 and CSS3.

Also it is called Front-end-framework.

Bootstrap is a free collection of tools for creating a websites and web applications.

It contains HTML and CSS-based design templates for typography, forms, buttons, navigation and other interface components, as well as optional JavaScript extensions.

Some Reasons for programmers preferred Bootstrap Framework

1. Easy to get started

2. Great grid system

3. Base styling for most HTML elements(Typography,Code,Tables,Forms,Buttons,Images,Icons)

4. Extensive list of components

5. Bundled Javascript plugins

Taken from About Bootstrap Framework

Just in case someone is using Bootstrap, I was able to add more than one class:

<a href="" class="baseclass" th:classappend="${isAdmin} ?: 'text-danger font-italic' "></a>

You also can use casting.

example:

string s;
int value = 3;
s.push_back((char)('0' + value));

The RSACryptoServiceProvider(CspParameters) constructor creates a keypair which is stored in the keystore on the local machine. If you already have a keypair with the specified name, it uses the existing keypair.

It sounds as if you are not interested in having the key stored on the machine.

So use the RSACryptoServiceProvider(Int32) constructor:

public static void AssignNewKey(){
    RSA rsa = new RSACryptoServiceProvider(2048); // Generate a new 2048 bit RSA key

    string publicPrivateKeyXML = rsa.ToXmlString(true);
    string publicOnlyKeyXML = rsa.ToXmlString(false);
    // do stuff with keys...
}

EDIT:

Alternatively try setting the PersistKeyInCsp to false:

public static void AssignNewKey(){
    const int PROVIDER_RSA_FULL = 1;
    const string CONTAINER_NAME = "KeyContainer";
    CspParameters cspParams;
    cspParams = new CspParameters(PROVIDER_RSA_FULL);
    cspParams.KeyContainerName = CONTAINER_NAME;
    cspParams.Flags = CspProviderFlags.UseMachineKeyStore;
    cspParams.ProviderName = "Microsoft Strong Cryptographic Provider";
    rsa = new RSACryptoServiceProvider(cspParams);

    rsa.PersistKeyInCsp = false;

    string publicPrivateKeyXML = rsa.ToXmlString(true);
    string publicOnlyKeyXML = rsa.ToXmlString(false);
    // do stuff with keys...
}

Use Instant to compute microseconds since Epoch:

val instant = Instant.now();
val currentTimeMicros = instant.getEpochSecond() * 1000_000 + instant.getNano() / 1000;

Update:

For mongodb versions 2.2+ more efficient way to do this described by @JohnnyHK in another answer.

1.Using $where

db.accommodations.find( { $where: "this.name.length > 1" } );

But...

Javascript executes more slowly than the native operators listed on this page, but is very flexible. See the server-side processing page for more information.

2.Create extra field NamesArrayLength, update it with names array length and then use in queries:

db.accommodations.find({"NamesArrayLength": {$gt: 1} });

It will be better solution, and will work much faster (you can create index on it).

No ... on all Windows platforms DWORD is 32 bits. LONGLONG or LONG64 is used for 64 bit types.

This is asking the wrong question. The right question to ask is, why am I spending time sorting socks? How much does it cost on yearly basis, when you value your free time for X monetary units of your choice?

And more often than not, this is not just any free time, it's morning free time, which you could be spending in bed, or sipping your coffee, or leaving a bit early and not being caught in the traffic.

It's often good to take a step back, and think a way around the problem.

And there is a way!

Find a sock you like. Take all relevant features into account: colour in different lighting conditions, overall quality and durability, comfort in different climatic conditions, and odour absorption. Also important is, they should not lose elasticity in storage, so natural fabrics are good, and they should be available in a plastic wrapping.

It's better if there's no difference between left and right foot socks, but it's not critical. If socks are left-right symmetrical, finding a pair is O(1) operation, and sorting the socks is approximate O(M) operation, where M is the number of places in your house, which you have littered with socks, ideally some small constant number.

If you chose a fancy pair with different left and right sock, doing a full bucket sort to left and right foot buckets take O(N+M), where N is the number of socks and M is same as above. Somebody else can give the formula for average iterations of finding the first pair, but worst case for finding a pair with blind search is N/2+1, which becomes astronomically unlikely case for reasonable N. This can be sped up by using advanced image recognition algorithms and heuristics, when scanning the pile of unsorted socks with Mk1 Eyeball.

So, an algorithm for achieving O(1) sock pairing efficiency (assuming symmetrical sock) is:

1. You need to estimate how many pairs of socks you will need for the rest of your life, or perhaps until you retire and move to warmer climates with no need to wear socks ever again. If you are young, you could also estimate how long it takes before we'll all have sock-sorting robots in our homes, and the whole problem becomes irrelevant.

2. You need to find out how you can order your selected sock in bulk, and how much it costs, and do they deliver.

3. Order the socks!

4. Get rid of your old socks.

An alternative step 3 would involve comparing costs of buying the same amount of perhaps cheaper socks a few pairs at a time over the years and adding the cost of sorting socks, but take my word for it: buying in bulk is cheaper! Also, socks in storage increase in value at the rate of stock price inflation, which is more than you would get on many investments. Then again there is also storage cost, but socks really do not take much space on the top shelf of a closet.

Problem solved. So, just get new socks, throw/donate your old ones away, and live happily ever after knowing you are saving money and time every day for the rest of your life.

You could use PHP's dirname function. <?php echo dirname(__DIR__); ?>. That will give you the name of the parent directory of __DIR__, which stores the current directory.

You can also do git push -u origin $(current_branch)

fn literally refers to the jquery prototype.

This line of code is in the source code:

jQuery.fn = jQuery.prototype = {
 //list of functions available to the jQuery api
}

But the real tool behind fn is its availability to hook your own functionality into jQuery. Remember that jquery will be the parent scope to your function, so this will refer to the jquery object.

$.fn.myExtension = function(){
 var currentjQueryObject = this;
 //work with currentObject
 return this;//you can include this if you would like to support chaining
};

So here is a simple example of that. Lets say I want to make two extensions, one which puts a blue border, and which colors the text blue, and I want them chained.

jsFiddle Demo

$.fn.blueBorder = function(){
 this.each(function(){
  $(this).css("border","solid blue 2px");
 });
 return this;
};
$.fn.blueText = function(){
 this.each(function(){
  $(this).css("color","blue");
 });
 return this;
};

Now you can use those against a class like this:

$('.blue').blueBorder().blueText();

(I know this is best done with css such as applying different class names, but please keep in mind this is just a demo to show the concept)

This answer has a good example of a full fledged extension.

Change to MyISAM engine and run this command

REPAIR TABLE tbl_name USE_FRM;

And, why not unobtrusive with jQuery:

  $(function() {
    $("#unobtrusive").click(function(e) {
      e.preventDefault(); // if desired...
      // other methods to call...
    });
  });

To get this in excel or csv format- right click the folder and select "copy response"- paste to excel and use text to columns.

Have you considered an event listener rather than setting the attribute? Among other things, it lets you pass parameters, which was a problem I ran into when trying to do this. You still have to do it twice for IE and Mozilla:

function makeEvent(element, callback, param, event) {
    function local() {
        return callback(param);
    }

    if (element.addEventListener) {
        //Mozilla
        element.addEventListener(event,local,false);
    } else if (element.attachEvent) {
        //IE
        element.attachEvent("on"+event,local);
    }
}

makeEvent(execBtn, alert, "hey buddy, what's up?", "click");

Just let event be a name like "click" or "mouseover".

Since dplyr 1.0.0, the across() function could be used:

df %>%
 group_by(Category) %>%
 summarise(across(Frequency, sum))

  Category Frequency
  <chr>        <int>
1 First           30
2 Second           5
3 Third           34

If interested in multiple variables:

df %>%
 group_by(Category) %>%
 summarise(across(c(Frequency, Frequency2), sum))

  Category Frequency Frequency2
  <chr>        <int>      <int>
1 First           30         55
2 Second           5         29
3 Third           34        190

And the selection of variables using select helpers:

df %>%
 group_by(Category) %>%
 summarise(across(starts_with("Freq"), sum))

  Category Frequency Frequency2 Frequency3
  <chr>        <int>      <int>      <dbl>
1 First           30         55        110
2 Second           5         29         58
3 Third           34        190        380

Sample data:

df <- read.table(text = "Category Frequency Frequency2 Frequency3
                 1    First        10         10         20
                 2    First        15         30         60
                 3    First         5         15         30
                 4   Second         2          8         16
                 5    Third        14         70        140
                 6    Third        20        120        240
                 7   Second         3         21         42",
                 header = TRUE,
                 stringsAsFactors = FALSE)

As Dennis says, you can't control how the browser chooses to handle target=_blank.

If you're wondering about the inconsistent behavior, probably it's pop-up blocking. Many browsers will forbid new windows from being opened apropos of nothing, but will allow new windows to be spawned as the eventual result of a mouse-click event.

SerialPort (RS-232 Serial COM Port) in C# .NET
This article explains how to use the SerialPort class in .NET to read and write data, determine what serial ports are available on your machine, and how to send files. It even covers the pin assignments on the port itself.

Example Code:

using System;
using System.IO.Ports;
using System.Windows.Forms;

namespace SerialPortExample
{
  class SerialPortProgram
  {
    // Create the serial port with basic settings
    private SerialPort port = new SerialPort("COM1",
      9600, Parity.None, 8, StopBits.One);

    [STAThread]
    static void Main(string[] args)
    { 
      // Instatiate this class
      new SerialPortProgram();
    }

    private SerialPortProgram()
    {
      Console.WriteLine("Incoming Data:");

      // Attach a method to be called when there
      // is data waiting in the port's buffer
      port.DataReceived += new 
        SerialDataReceivedEventHandler(port_DataReceived);

      // Begin communications
      port.Open();

      // Enter an application loop to keep this thread alive
      Application.Run();
    }

    private void port_DataReceived(object sender,
      SerialDataReceivedEventArgs e)
    {
      // Show all the incoming data in the port's buffer
      Console.WriteLine(port.ReadExisting());
    }
  }
}

A big difference is if you are displaying arrays. Especially ones with NIL. For example:

print [nil, 1, 2]

gives

[nil, 1, 2]

but

puts [nil, 1, 2]

gives

1
2

Note, no appearing nil item (just a blank line) and each item on a different line.

I have a simple script I use for this:

me@mycomputer:~$ cat /usr/local/bin/c

#!/bin/sh

echo "$*" | sed 's/x/\*/g' | bc -l

It changes x to * since * is a special character in the shell. Use it as follows:

• c 5x5
• c 5-4.2 + 1
• c '(5 + 5) * 30' (you still have to use quotes if the expression contains any parentheses).

Maybe not the best solution, (will rewrite history) but you could also do git reset --hard <hash of detached head commit>.

Since you ask for the easiest way, I suggest using vagrant-scp. It adds a scp command to vagrant, so you can copy files to your VM like you would normally do with scp.

Install via:

vagrant plugin install vagrant-scp

Use it like so:

vagrant scp <some_local_file_or_dir> [vm_name]:<somewhere_on_the_vm>

Use position: fixed, and anchor it to the top and right sides of the page:

#fixed-div {
    position: fixed;
    top: 1em;
    right: 1em;
}

IE6 does not support position: fixed, however. If you need this functionality in IE6, this purely-CSS solution seems to do the trick. You'll need a wrapper <div> to contain some of the styles for it to work, as seen in the stylesheet.

OK this is working well From the suggestions above GetRange( ) does not work for me with a list as an argument...so sweetening things up a bit from posts above: ( thanks everyone :)

/*  Where __strBuf is a string list used as a dumping ground for data  */
public List < string > pullStrLst( )
{
    List < string > lst;

    lst = __strBuf.GetRange( 0, __strBuf.Count );     

    __strBuf.Clear( );

    return( lst );
}

<div class="content"> 
  Counter-Strike 1.6 Steam 
     <img src="images/CSsteam.png">
     <a href="#">Koupit</a>
</div>

/*Use this css*/
content {
width: 182px; /*328 co je 1/3 - 20margin left*/
height: 121px;
line-height: 20px;
margin-top: 0px;
margin-left: 9px;
margin-right:0px;
display:inline-block;
position:relative;
}
content a{
display:inline-block;
padding:10px;
position:absolute;
bottom:10px;

}

If you want to save lines of code and leave the most flexible solution, we can deserialize the json string to a dynamic object:

p = lambda:None
p.__dict__ = json.loads('{"action": "print", "method": "onData", "data": "Madan Mohan"}')

>>>> p.action
output: u'print'

>>>> p.method
output: u'onData'

I also found that this works fine too, and its a lot shorter than the other examples.

if (myVar === myVar + '') {
   //its string
} else {
   //its something else
}

By concatenating on empty quotes it turns the value into a string. If myVar is already a string then the if statement is successful.

You have to add the FormHttpMessageConverter to your applicationContext.xml to be able to post multipart files.

<bean id="restTemplate" class="org.springframework.web.client.RestTemplate">
    <property name="messageConverters">
        <list>
            <bean class="org.springframework.http.converter.StringHttpMessageConverter" />
            <bean class="org.springframework.http.converter.FormHttpMessageConverter" />
        </list>
    </property>
</bean>

See http://docs.spring.io/spring-framework/docs/current/javadoc-api/org/springframework/http/converter/FormHttpMessageConverter.html for examples.

For cleaning Immediate window I use (VBA Excel 2016) next function:

Private Sub ClrImmediate()
   With Application.VBE.Windows("Immediate")
       .SetFocus
       Application.SendKeys "^g", True
       Application.SendKeys "^a", True
       Application.SendKeys "{DEL}", True
   End With
End Sub

But direct call of ClrImmediate() like this:

Sub ShowCommandBarNames()
    ClrImmediate
 '--   DoEvents    
    Debug.Print "next..."
End Sub

works only if i put the breakpoint on Debug.Print, otherwise the clearing will be done after execution of ShowCommandBarNames() - NOT before Debug.Print. Unfortunately, call of DoEvents() did not help me... And no matter: TRUE or FALSE is set for SendKeys.

To solve this I use next couple of calls:

Sub ShowCommandBarNames()
 '--    ClrImmediate
    Debug.Print "next..."
End Sub

Sub start_ShowCommandBarNames()
   ClrImmediate
   Application.OnTime Now + TimeSerial(0, 0, 1), "ShowCommandBarNames"
End Sub

It seems to me that using Application.OnTime might be very useful in programming for VBA IDE. In this case it's can be used even TimeSerial(0, 0, 0).

If you mean the screen where you have that interpreter prompt >>> you can do CTRL+L on Bash shell can help. Windows does not have equivalent. You can do

import os
os.system('cls')  # on windows

or

os.system('clear')  # on linux / os x

Note that -(NSString *)tableView: titleForHeaderInSection: is not called by UITableView if - (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section is implemented in delegate of UITableView;

If you're using SQL Server 2005 or above, you can use the windowing function SUM() OVER ().

case 
when test1.TotalType = 'Average' then Test2.avgscore
when test1.TotalType = 'PercentOfTot' then (cnt/SUM(test1.qrank) over ())
else cnt
end as displayscore

But it'll be better if you show your full query to get context of what you actually need.

Java is compiled to bytecode, which then goes into the Java VM, which interprets it.

Works fine for me

See example here. http://jsfiddle.net/blowsie/c6VAy/

Make sure your jquery is inside $(document).ready function or similar.

Also you can improve your code by using jquery data

$('#amount').data('min','1000');

<div id="amount" data-min=""></div>

Update,

A working example of your full code (pretty much) here. http://jsfiddle.net/blowsie/c6VAy/3/

Simply use the question mark trick for null checks:

string displayName = Dictionary.FirstOrDefault(x => x.Value.ID == long.Parse(options.ID))?.Value.DisplayName ?? "DEFINE A DEFAULT DISPLAY NAME HERE";

You need to read and write document.cookie

if (document.cookie.indexOf("visited=") >= 0) {
  // They've been here before.
  alert("hello again");
}
else {
  // set a new cookie
  expiry = new Date();
  expiry.setTime(expiry.getTime()+(10*60*1000)); // Ten minutes

  // Date()'s toGMTSting() method will format the date correctly for a cookie
  document.cookie = "visited=yes; expires=" + expiry.toGMTString();
  alert("this is your first time");
}

This work for me:

cache:clear --env=prod

select * from table where value % 2 = 1 works fine in mysql.

The else is only connected to the last if. You want elif:

if 'bad' in line:
    pass
elif 'naughty' in line:
    pass
else:
    newopen.write(line)

Also note that I removed the line substitution, as you don't write those lines anyway.

I guess this document might serve as a not so short introduction : n3055

The whole massacre began with the move semantics. Once we have expressions that can be moved and not copied, suddenly easy to grasp rules demanded distinction between expressions that can be moved, and in which direction.

From what I guess based on the draft, the r/l value distinction stays the same, only in the context of moving things get messy.

Are they needed? Probably not if we wish to forfeit the new features. But to allow better optimization we should probably embrace them.

Quoting n3055:

• An lvalue (so-called, historically, because lvalues could appear on the left-hand side of an assignment expression) designates a function or an object. [Example: If E is an expression of pointer type, then *E is an lvalue expression referring to the object or function to which E points. As another example, the result of calling a function whose return type is an lvalue reference is an lvalue.]
• An xvalue (an “eXpiring” value) also refers to an object, usually near the end of its lifetime (so that its resources may be moved, for example). An xvalue is the result of certain kinds of expressions involving rvalue references. [Example: The result of calling a function whose return type is an rvalue reference is an xvalue.]
• A glvalue (“generalized” lvalue) is an lvalue or an xvalue.
• An rvalue (so-called, historically, because rvalues could appear on the right-hand side of an assignment expression) is an xvalue, a temporary object or subobject thereof, or a value that is not associated with an object.
• A prvalue (“pure” rvalue) is an rvalue that is not an xvalue. [Example: The result of calling a function whose return type is not a reference is a prvalue]

The document in question is a great reference for this question, because it shows the exact changes in the standard that have happened as a result of the introduction of the new nomenclature.

The width attribute of <td> is deprecated in HTML 5.

Use CSS. e.g.

 <td style="width:100px">

in detail, like this:

<table >
  <tr>
    <th>Month</th>
    <th>Savings</th>
  </tr>
  <tr>
    <td style="width:70%">January</td>
    <td style="width:30%">$100</td>
  </tr>
  <tr>
    <td>February</td>
    <td>$80</td>
  </tr>
</table>

To create a spreadsheet and format a cell using POI, see the Working with Fonts example, and use:

font.setBoldweight(Font.BOLDWEIGHT_BOLD);

POI works very well. There are some things you can't do (e.g. create VBA macros), but it'll read/write spreadsheets with macros, so you can create a suitable template sheet, read it and manipulate it with POI, and then write it out.

I had the same on Android. This is how i fixed it:

including ONLY the file:

slf4j-api-1.7.6.jar

in my libs/ folder

Having any additional slf4j* file, caused the NoClassDefFoundError.

Obviously, the rest of the libs can be there (android-support-v4, etc)

Versions: Eclipse Kepler 2013 06 14 - 02 29 ADT 22.3 Android SDK: 4.4.2

Hope someone saves the time i wasted thanks to this!

This is my sample code for load static variable

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Component;

@Component
public class OnelinkConfig {
    public static int MODULE_CODE;
    public static int DEFAULT_PAGE;
    public static int DEFAULT_SIZE;

    @Autowired
    public void loadOnelinkConfig(@Value("${onelink.config.exception.module.code}") int code,
            @Value("${onelink.config.default.page}") int page, @Value("${onelink.config.default.size}") int size) {
        MODULE_CODE = code;
        DEFAULT_PAGE = page;
        DEFAULT_SIZE = size;
    }
}
