Based on your comments in this answer, I do what you're trying to do like this:

module.exports = function (app, db) {
    var module = {};

    module.auth = function (req, res) {
        // This will be available 'outside'.
        // Authy stuff that can be used outside...
    };

    // Other stuff...
    module.pickle = function(cucumber, herbs, vinegar) {
        // This will be available 'outside'.
        // Pickling stuff...
    };

    function jarThemPickles(pickle, jar) {
        // This will be NOT available 'outside'.
        // Pickling stuff...

        return pickleJar;
    };

    return module;
};

I structure pretty much all my modules like that. Seems to work well for me.

Append ll suffix to hex digits for 64-bit (long long int), or ull suffix for unsigned 64-bit (unsigned long long)

To get the value from the servlet from POST command, you can follow the approach as explained on this post by using request.getParameter(key) format which will return the value you want.

In order to link the issue number to your commit message, you should add: #issue_number in your git commit message.

Example Commit Message from Udacity Git Commit Message Style Guide

feat: Summarize changes in around 50 characters or less

More detailed explanatory text, if necessary. Wrap it to about 72
characters or so. In some contexts, the first line is treated as the
subject of the commit and the rest of the text as the body. The
blank line separating the summary from the body is critical (unless
you omit the body entirely); various tools like `log`, `shortlog`
and `rebase` can get confused if you run the two together.

Explain the problem that this commit is solving. Focus on why you
are making this change as opposed to how (the code explains that).
Are there side effects or other unintuitive consequenses of this
change? Here's the place to explain them.

Further paragraphs come after blank lines.

 - Bullet points are okay, too

 - Typically a hyphen or asterisk is used for the bullet, preceded
   by a single space, with blank lines in between, but conventions
   vary here

If you use an issue tracker, put references to them at the bottom,
like this:

Resolves: #123
See also: #456, #789

You can also reference the repositories:

My answer is "neither one".

I believe the most "Pythonic" way to do things is to NOT check beforehand if the key is in a dictionary and instead just write code that assumes it's there and catch any KeyErrors that get raised because it wasn't.

This is usually done with enclosing the code in a try...except clause and is a well-known idiom usually expressed as "It's easier to ask forgiveness than permission" or with the acronym EAFP, which basically means it is better to try something and catch the errors instead for making sure everything's OK before doing anything. Why validate what doesn't need to be validated when you can handle exceptions gracefully instead of trying to avoid them? Because it's often more readable and the code tends to be faster if the probability is low that the key won't be there (or whatever preconditions there may be).

Of course, this isn't appropriate in all situations and not everyone agrees with the philosophy, so you'll need to decide for yourself on a case-by-case basis. Not surprisingly the opposite of this is called LBYL for "Look Before You Leap".

As a trivial example consider:

if 'name' in dct:
    value = dct['name'] * 3
else:
    logerror('"%s" not found in dictionary, using default' % name)
    value = 42

vs

try:
    value = dct['name'] * 3
except KeyError:
    logerror('"%s" not found in dictionary, using default' % name)
    value = 42

Although in the case it's almost exactly the same amount of code, the second doesn't spend time checking first and is probably slightly faster because of it (try...except block isn't totally free though, so it probably doesn't make that much difference here).

Generally speaking, testing in advance can often be much more involved and the savings gain from not doing it can be significant. That said, if 'name' in dict: is better for the reasons stated in the other answers.

If you're interested in the topic, this message titled "EAFP vs LBYL (was Re: A little disappointed so far)" from the Python mailing list archive probably explains the difference between the two approached better than I have here. There's also a good discussion about the two approaches in the book Python in a Nutshell, 2nd Ed by Alex Martelli in chapter 6 on Exceptions titled Error-Checking Strategies. (I see there's now a newer 3rd edition, publish in 2017, which covers both Python 2.7 and 3.x).

A CRC is pretty simple; you take a polynomial represented as bits and the data, and divide the polynomial into the data (or you represent the data as a polynomial and do the same thing). The remainder, which is between 0 and the polynomial is the CRC. Your code is a bit hard to understand, partly because it's incomplete: temp and testcrc are not declared, so it's unclear what's being indexed, and how much data is running through the algorithm.

The way to understand CRCs is to try to compute a few using a short piece of data (16 bits or so) with a short polynomial -- 4 bits, perhaps. If you practice this way, you'll really understand how you might go about coding it.

If you're doing it frequently, a CRC is quite slow to compute in software. Hardware computation is much more efficient, and requires just a few gates.

I found a simple way

    TrustStrategy acceptingTrustStrategy = (X509Certificate[] chain, String authType) -> true;
    SSLContext sslContext = org.apache.http.ssl.SSLContexts.custom().loadTrustMaterial(null, acceptingTrustStrategy).build();
    SSLConnectionSocketFactory csf = new SSLConnectionSocketFactory(sslContext);
    CloseableHttpClient httpClient = HttpClients.custom().setSSLSocketFactory(csf).build();
    HttpComponentsClientHttpRequestFactory requestFactory = new HttpComponentsClientHttpRequestFactory();
    requestFactory.setHttpClient(httpClient);

    RestTemplate restTemplate = new RestTemplate(requestFactory);

I ran into this related issue even after having already successfully run composer. I updated composer, and when running composer install or php composer.phar install I got:

...failed to open stream: Permission denied...

It turns out after much research that the previous answers regarding changing permissions for the folder worked. They are just slightly different directories now.

In my install, on OS X, the cache file is in /Users/[USER]/.composer/cache, and I was having trouble because the cache file was owned by root. Changing ownership of '.composer' recursively to my user solved the issue.

This is what I did:

sudo chown -R [USER] cache

Then I ran the composer install again and voila!

Depending on your need you can use one of following method:

• In first line/s of view add "using your.domainName;" (if it is required in specific view only)

• if required in all subsequent views then add "using your.domainName;" in _ViewStart.cshtml. You can find more about this in: Where and how is the _ViewStart.cshtml layout file linked?

• Or add Assembly reference in View web.config as described by others explained in: How do you implement a @using across all Views in Asp.Net MVC 3?

You have two options here:

• Option one, Anchor
• Option two, Dock

Look for both properties and figure out which one suit your needs.

This error will happen too even if the FormsModule is imported directly or indirectly (from a shared module for example) in the feature module, if the imported component is not declared on declarations:

I followed Deborah Kurata's Angular Routing course. While I added the imported component ProductEditInfoComponent on Angular Route's component property, I forgot to add ProductEditInfoComponent on declarations property.

Adding the ProductEditInfoComponent on the declarations property would solve the NG8002: Can't bind to 'ngModel' since it isn't a known property of 'input'. problem:

Share Any File as below ( Kotlin ) :
first create a folder named xml in the res folder and create a new XML Resource File named provider_paths.xml and put the below code inside it :

<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
    <files-path
        name="files"
        path="."/>

    <external-path
        name="external_files"
        path="."/>
</paths>

now go to the manifests folder and open the AndroidManifest.xml and then put the below code inside the <application> tag :

<provider
android:name="androidx.core.content.FileProvider"
android:authorities="${applicationId}.provider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
    android:name="android.support.FILE_PROVIDER_PATHS"
    android:resource="@xml/provider_paths" /> // provider_paths.xml file path in this example
</provider>

now you put the below code in the setOnLongClickListener :

share_btn.setOnClickListener {
    try {
        val file = File("pathOfFile")
        if(file.exists()) {
            val uri = FileProvider.getUriForFile(this, BuildConfig.APPLICATION_ID + ".provider", file)
            val intent = Intent(Intent.ACTION_SEND)
            intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION)
            intent.setType("*/*")
            intent.putExtra(Intent.EXTRA_STREAM, uri)
            intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            startActivity(intent)
        }
    } catch (e: java.lang.Exception) {
        e.printStackTrace()
        toast("Error")
    }
}

With Java 8 or newer, you can use String.join, which provides the same functionality:

Returns a new String composed of copies of the CharSequence elements joined together with a copy of the specified delimiter

String[] array = new String[] { "a", "n", "d", "r", "o", "i", "d" };
String joined = String.join("", array); //returns "android"

With an array of a different type, one should convert it to a String array or to a char sequence Iterable:

int[] numbers = { 1, 2, 3, 4, 5, 6, 7 };

//both of the following return "1234567"
String joinedNumbers = String.join("",
        Arrays.stream(numbers).mapToObj(String::valueOf).toArray(n -> new String[n]));
String joinedNumbers2 = String.join("",
        Arrays.stream(numbers).mapToObj(String::valueOf).collect(Collectors.toList()));

The first argument to String.join is the delimiter, and can be changed accordingly.

A .tex file should be a LaTeX source file.

If this is the case, that file contains the source code for a LaTeX document. You can open it with any text editor (notepad, notepad++ should work) and you can view the source code. But if you want to view the final formatted document, you need to install a LaTeX distribution and compile the .tex file.

Of course, any program can write any file with any extension, so if this is not a LaTeX document, then we can't know what software you need to install to open it. Maybe if you upload the file somewhere and link it in your question we can see the file and provide more help to you.

Yes, this is the source code of a LaTeX document. If you were able to paste it here, then you are already viewing it. If you want to view the compiled document, you need to install a LaTeX distribution. You can try to install MiKTeX then you can use that to compile the document to a .pdf file.

You can also check out this question and answer for how to do it: How to compile a LaTeX document?

Also, there's an online LaTeX editor and you can paste your code in there to preview the document: https://www.overleaf.com/.

You can use ggplot2 to rotate the x-axis label adding an additional layer

theme(axis.text.x = element_text(angle = 90, hjust = 1))

Well, you're getting a java.lang.NoClassDefFoundError. In your pom.xml, hibernate-core version is 3.3.2.GA and declared after hibernate-entitymanager, so it prevails. You can remove that dependency, since will be inherited version 3.6.7.Final from hibernate-entitymanager.

You're using spring-boot as parent, so no need to declare version of some dependencies, since they are managed by spring-boot.

Also, hibernate-commons-annotations is inherited from hibernate-entitymanager and hibernate-annotations is an old version of hibernate-commons-annotations, you can remove both.

Finally, your pom.xml can look like this:

Let me know if you have a problem.

I've used the "slugify" method from underscore.string and it worked like a charm:

https://github.com/epeli/underscore.string#slugifystring--string

The cool thing is that you can really just import this method, don't need to import the entire library.

First creates the function

$.UrlExists = function(url) {_x000D_
 var http = new XMLHttpRequest();_x000D_
    http.open('HEAD', url, false);_x000D_
    http.send();_x000D_
    return http.status!=404;_x000D_
}

After using the function as follows

if($.UrlExists("urlimg")){_x000D_
 foto = "img1.jpg";_x000D_
}else{_x000D_
 foto = "img2.jpg";_x000D_
}_x000D_
_x000D_
$('<img>').attr('src',foto);

This is simple solution for get a list of dates

import java.io.*;
import java.util.*;
import java.text.SimpleDateFormat;  
public class DateList
{

public static SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd");

 public static void main (String[] args) throws java.lang.Exception
 {

    Date dt = new Date();
    System.out.println(dt);

        List<Date> dates = getDates("2017-01-01",dateFormat.format(new Date()));
        //IF you don't want to reverse then remove Collections.reverse(dates);
         Collections.reverse(dates);
        System.out.println(dates.size());
    for(Date date:dates)
    {
        System.out.println(date);
    }
 }
 public static List<Date> getDates(String fromDate, String toDate)
 {
    ArrayList<Date> dates = new ArrayList<Date>();

    try {

        Calendar fromCal = Calendar.getInstance();
        fromCal.setTime(dateFormat .parse(fromDate));

        Calendar toCal = Calendar.getInstance();
        toCal.setTime(dateFormat .parse(toDate));

        while(!fromCal.after(toCal))
        {
            dates.add(fromCal.getTime());
            fromCal.add(Calendar.DATE, 1);
        }


    } catch (Exception e) {
        System.out.println(e);
    }
    return dates;
 }
}

A huge collection of useful icons is easily accessible like this:

1. Right click on Drawable folder
2. Click on New
3. Click on Vector Asset
4. In the dialog, click the button in the third row with a random icon, next to the label "Clip Art:". You can pick from the huge collection, then customize size and color.

By combining the multicol package and enumitem package packages it is easy to define environments that are multi-column analogues of the enumerate and itemize environments:

\documentclass{article}
\usepackage{enumitem}
\usepackage{multicol}

\newlist{multienum}{enumerate}{1}
\setlist[multienum]{
    label=\alph*),
    before=\begin{multicols}{2},
    after=\end{multicols}
}

\newlist{multiitem}{itemize}{1}
\setlist[multiitem]{
    label=\textbullet,
    before=\begin{multicols}{2},
    after=\end{multicols}
}

\begin{document}

  \textsf{Two column enumerate}
  \begin{multienum}
    \item item 1
    \item item 2
    \item item 3
    \item item 4
    \item item 5
    \item item 6
  \end{multienum}

  \textsf{Two column itemize}
  \begin{multiitem}
    \item item 1
    \item item 2
    \item item 3
    \item item 4
    \item item 5
    \item item 6
  \end{multiitem}

\end{document}

The output is what you would hope for:

We can set font as per our requirement like,

label.font = UIFont(name: "Avenir-Light", size: 15.0)
label.font = UIFont.boldSystemFontOfSize(15)
label.font = UIFont.italicSystemFontOfSize(15)
label.font = UIFont.systemFontOfSize(17)

Update:

There were 2 key parts to my question:

1. How to make a link where the text shown for the clickable link is different than the actual link that is invoked:
2. How to set up the links without having to use custom code to set the attributes on the text.

It turns out that iOS 7 added the ability to load attributed text from NSData.

I created a custom subclass of UITextView that takes advantage of the @IBInspectable attribute and lets you load contents from an RTF file directly in IB. You simply type the filename into IB and the custom class does the rest.

Here are the details:

In iOS 7, NSAttributedString gained the method initWithData:options:documentAttributes:error:. That method lets you load an NSAttributedString from an NSData object. You can first load an RTF file into NSData, then use initWithData:options:documentAttributes:error: to load that NSData into your text view. (Note that there is also a method initWithFileURL:options:documentAttributes:error: that will load an attributed string directly from a file, but that method was deprecated in iOS 9. It's safer to use the method initWithData:options:documentAttributes:error:, which wasn't deprecated.

I wanted a method that let me install clickable links into my text views without having to create any code specific to the links I was using.

The solution I came up with was to create a custom subclass of UITextView I call RTF_UITextView and give it an @IBInspectable property called RTF_Filename. Adding the @IBInspectable attribute to a property causes Interface Builder to expose that property in the "Attributes Inspector." You can then set that value from IB wihtout custom code.

I also added an @IBDesignable attribute to my custom class. The @IBDesignable attribute tells Xcode that it should install a running copy of your custom view class into Interface builder so you can see it in the graphical display of your view hierarchy. ()Unfortunately, for this class, the @IBDesignable property seems to be flaky. It worked when I first added it, but then I deleted the plain text contents of my text view and the clickable links in my view went away and I have not been able to get them back.)

The code for my RTF_UITextView is very simple. In addition to adding the @IBDesignable attribute and an RTF_Filename property with the @IBInspectable attribute, I added a didSet() method to the RTF_Filename property. The didSet() method gets called any time the value of the RTF_Filename property changes. The code for the didSet() method is quite simple:

@IBDesignable
class RTF_UITextView: UITextView
{
  @IBInspectable
  var RTF_Filename: String?
    {
    didSet(newValue)
    {
      //If the RTF_Filename is nil or the empty string, don't do anything
      if ((RTF_Filename ?? "").isEmpty)
      {
        return
      }
      //Use optional binding to try to get an URL to the
      //specified filename in the app bundle. If that succeeds, try to load
      //NSData from the file.
      if let fileURL = NSBundle.mainBundle().URLForResource(RTF_Filename, withExtension: "rtf"),
        
        //If the fileURL loads, also try to load NSData from the URL.
        let theData = NSData(contentsOfURL: fileURL)
      {
        var aString:NSAttributedString
        do
        {
          //Try to load an NSAttributedString from the data
          try
            aString = NSAttributedString(data: theData,
              options: [:],
              documentAttributes:  nil
          )
          //If it succeeds, install the attributed string into the field.
          self.attributedText = aString;
        }
        catch
        {
          print("Nerp.");
        }
      }
      
    }
  }
}

Note that if the @IBDesignable property isn't going to reliably allow you to preview your styled text in Interface builder then it might be better to set the above code up as an extension of UITextView rather than a custom subclass. That way you could use it in any text view without having to change the text view to the custom class.

See my other answer if you need to support iOS versions prior to iOS 7.

You can download a sample project that includes this new class from gitHub:

DatesInSwift demo project on Github

You need to subscribe to the KeyDown event on the text box. Then something like this:

private void textBox1_KeyDown(object sender, System.Windows.Forms.KeyEventArgs e)
{
    if (!char.IsControl(e.KeyChar) 
       && !char.IsDigit(e.KeyChar) 
       && e.KeyChar != '.' && e.KeyChar != '+' && e.KeyChar != '-'
       && e.KeyChar != '(' && e.KeyChar != ')' && e.KeyChar != '*' 
       && e.KeyChar != '/')
    {
        e.Handled = true;
        return;
    }
    e.Handled=false;
    return;
}

The important thing to know is that if you changed the Handled property to true, it will not process the keystroke. Setting it to false will.

A simpler solution on recent versions of tmux (tested on 1.9) you can now do :

tmux detach -a

-a is for all other client on this session except the current one

You can alias it in your .[bash|zsh]rc

alias takeover="tmux detach -a"

Workflow: You can connect to your session normally, and if you are bothered by another session that forced down your tmux window size you can simply call takeover.

In my case, I was using it on an element instead of document, and according to MDN:

Unlike some other element-lookup methods such as Document.querySelector() and Document.querySelectorAll(), getElementById() is only available as a method of the global document object, and not available as a method on all element objects in the DOM. Because ID values must be unique throughout the entire document, there is no need for "local" versions of the function.

I had the same problem in Google App Scripts, and solved it like the rest said, but with a little more..

function refreshGrid(entity) {
var store = window.localStorage;
var partitionKey;
if (condition) {
  return Browser.msgBox("something");
  }
}

This way you not only exit the function, but show a message saying why it stopped. Hope it helps.

Create a global variable in and apply the value

<script>
       var isPostBack = <%=Convert.ToString(Page.IsPostBack).ToLower()%>;
</script>

Then you can reference it from elsewhere

It seems no one has mentioned about using nonNull method which also can be used with streams in Java 8 to remove null (but not empty) as:

String[] origArray = {"Apple", "", "Cat", "Dog", "", null};
String[] cleanedArray = Arrays.stream(firstArray).filter(Objects::nonNull).toArray(String[]::new);
System.out.println(Arrays.toString(origArray));
System.out.println(Arrays.toString(cleanedArray));

And the output is:

[Apple, , Cat, Dog, , null]

[Apple, , Cat, Dog, ]

If we want to incorporate empty also then we can define a utility method (in class Utils(say)):

public static boolean isEmpty(String string) {
        return (string != null && string.isEmpty());
    }

And then use it to filter the items as:

Arrays.stream(firstArray).filter(Utils::isEmpty).toArray(String[]::new);

I believe Apache common also provides a utility method StringUtils.isNotEmpty which can also be used.

I found the solution with this link : http://pixelsvsbytes.com/blog/2013/02/nice-web-fonts-for-every-browser/

Step by step method :

• send your font to a WebFontGenerator and get the zip
• find the TTF font on the Zip file
• then, on linux, do this command (or install by apt-get install ttfautohint):
  ttfautohint --strong-stem-width=g neosansstd-black.ttf neosansstd-black.changed.ttf
• then, one more, send the new TTF file (neosansstd-black.changed.ttf) on the WebFontGenerator
• you get a perfect Zip with all your webfonts !

I hope this will help.

That is not an error; the make command in unix works based on the timestamps. I.e let's say if you have made certain changes to factorial.cpp and compile using make then make shows the information that only the cc -o factorial.cpp command is executed. Next time if you execute the same command i.e make without making any changes to any file with .cpp extension the compiler says that the output file is up to date. The compiler gives this information until we make certain changes to any file.cpp.

The advantage of the makefile is that it reduces the recompiling time by compiling the only files that are modified and by using the object (.o) files of the unmodified files directly.

I recommend a generic solution so you don't have to add the code for every form. Use the jquery form plugin (http://jquery.malsup.com/form/) and add this code.

$(function(){
$('form.ajax_submit').submit(function() {
    $(this).ajaxSubmit();
            //validation and other stuff
        return false; 
});

});

• You can do this without installing anything into python itself.

• You don't need sudo or any privileges.

• You don't need to find the latest version of a virtualenv tar file

• You don't need to edit version info in a bash script to keep things up-to-date.

• You don't need curl/wget or tar installed, nor pip or easy_install

• this works for 2.7 as well as for 3.X

Save the following to /tmp/initvenv.py:

from future import print_function

import os, sys, shutil, tempfile, subprocess, tarfile, hashlib

try:
    from urllib2 import urlopen
except ImportError:
    from urllib.request import urlopen

tmp_dir = tempfile.mkdtemp(prefix='initvenv_')
try:
    # read the latest version from PyPI
    f = urlopen("https://pypi.python.org/pypi/virtualenv/")
    # retrieve the .tar.gz file
    tar_found = False
    url = None
    sha256 = None
    for line in f.read().splitlines():
        if isinstance(line, bytes):
            line = line.decode('utf-8')
        if tar_found:
            if 'sha256' in line:
                sha256 = line.split('data-clipboard-text')[1].split('"')[1]
                break
            continue
        if not tar_found and 'tar.gz">' not in line:
            continue
        tar_found = True
        for url in line.split('"'):
            if url.startswith('https'):
                break
    else:
        print('tar.gz not found')
        sys.exit(1)
    file_name = url.rsplit('/', 1)[1]
    print(file_name)
    os.chdir(tmp_dir)
    data = urlopen(url).read()
    data_sha256 = hashlib.sha256(data).hexdigest()
    if sha256 != data_sha256:
        print('sha256 not correct')
        print(sha256)
        print(data_sha256)
        sys.exit(1)
    with open(file_name, 'wb') as fp:
        fp.write(data)
    tar = tarfile.open(file_name)
    tar.extractall()
    tar.close()
    os.chdir(file_name.replace('.tar.gz', ''))
    print(subprocess.check_output([sys.executable, 'virtualenv.py'] +
                                  [sys.argv[1]]).decode('utf-8'), end='')
    if len(sys.argv) > 2:
        print(subprocess.check_output([
            os.path.join(sys.argv[1], 'bin', 'pip'), 'install', 'virtualenv'] +

            sys.argv[2:]).decode('utf-8'), end='')
except:
    raise
finally:
    shutil.rmtree(tmp_dir)  # always clean up

and use it as

python_binary_to_use_in_venv /tmp/initvenv.py your_venv_name [optional packages]

e.g. (if you really need the distribute compatibility layer for setuptools)

python /tmp/initvenv.py venv distribute

Please note that, with older python versions, this might give you InsecurePlatformWarnings¹.

Once you have your virtualenv (name e.g. venv) you can setup another virtualenv by using the virtualenv just installed:

venv/bin/virtualenv venv2

virtualenvwrapper

I recommend taking a look at virtualenvwrapper as well, after a one time setup:

% /opt/python/2.7.10/bin/python /tmp/initvenv.py venv virtualenvwrapper

and activation (can be done from your login script):

% source venv/bin/virtualenvwrapper.sh

you can do things like:

% mktmpenv 
New python executable in tmp-17bdc3054a46b2b/bin/python
Installing setuptools, pip, wheel...done.
This is a temporary environment. It will be deleted when you run 'deactivate'.
(tmp-17bdc3054a46b2b)% 

¹ _{I have not found a way to suppress the warning. It could be solved in pip and/or request, but the developers point to each other as the cause. I got the, often non-realistic, recommendation to upgrade the python version I was using to the latest version. I am sure this would break e.g my Linux Mint 17 install. Fortunately pip caches packages, so the Warning is made only once per package install.}

If you met the problem after upgrading php-fpm like me, try this: open /etc/php5/fpm/pool.d/www.conf uncomment the following lines:

listen.owner = www-data
listen.group = www-data
listen.mode = 0666

then restart php-fpm.

Using Newton C++

bool exists_linear( INPUT_ITERATOR first, INPUT_ITERATOR last, const T& value )

bool exists_binary( INPUT_ITERATOR first, INPUT_ITERATOR last, const T& value )

the code will be something like this:

if ( newton::exists_linear(arr.begin(), arr.end(), value) )
   std::cout << "found" << std::endl;
else
   std::cout << "not found" << std::endl;

both exists_linear and exists_binary use std implementations. binary use std::binary_search, and linear use std::find, but return directly a bool, not an iterator.

int RoundedUp = (int) Math.ceil(RandomReal);

This seemed to do the perfect job. Worked everytime.

use SimpleDateFormat df = new SimpleDateFormat("HH:mm"); instead

UPDATE

@Ingo is right. is's better use setTime(d1);

first method getHours() and getMinutes() is now deprecated

I test this code

SimpleDateFormat df = new SimpleDateFormat("hh:mm");
  Date d1 = df.parse("23:30");
  Calendar c1 = GregorianCalendar.getInstance();
  c1.setTime(d1);
  System.out.println(c1.getTime());

and output is ok Thu Jan 01 23:30:00 FET 1970

try this

SimpleDateFormat df = new SimpleDateFormat("KK:mm aa");
  Date d1 = df.parse("10:30 PM");
  Calendar c1 = GregorianCalendar.getInstance(Locale.US);
  SimpleDateFormat sdf = new SimpleDateFormat("HH:mm:ss");  
  c1.setTime(d1);
  String str = sdf.format(c1.getTime());
  System.out.println(str);

Interestingly no one answers the question, OP isn't using a strongly typed int[] but an Array.

You have to cast the Array to what it actually is, an int[], then you can use ToList:

List<int> intList = ((int[])ints).ToList();

Note that Enumerable.ToList calls the list constructor that first checks if the argument can be casted to ICollection<T>(which an array implements), then it will use the more efficient ICollection<T>.CopyTo method instead of enumerating the sequence.

This happens because the scipy module doesn't have any attribute named sparse. That attribute only gets defined when you import scipy.sparse.

Submodules don't automatically get imported when you just import scipy; you need to import them explicitly. The same holds for most packages, although a package can choose to import its own submodules if it wants to. (For example, if scipy/__init__.py included a statement import scipy.sparse, then the sparse submodule would be imported whenever you import scipy.)

For ListView or GridView there is an another difference, when visibility initially set to

INVISIBLE:

Adapter's getView() function called

GONE:

Adapter's getView() function didn't call, thus preventing views to load, when it is unnecessary

Let's fit the model:

Below is an adaptation of previous code for using under PyQt5 and Matplotlib 2.0. There are a number of small changes: structure of PyQt submodules, other submodule from matplotlib, deprecated method has been replaced...

import sys
from PyQt5.QtWidgets import QDialog, QApplication, QPushButton, QVBoxLayout

from matplotlib.backends.backend_qt5agg import FigureCanvasQTAgg as FigureCanvas
from matplotlib.backends.backend_qt5agg import NavigationToolbar2QT as NavigationToolbar
import matplotlib.pyplot as plt

import random

class Window(QDialog):
    def __init__(self, parent=None):
        super(Window, self).__init__(parent)

        # a figure instance to plot on
        self.figure = plt.figure()

        # this is the Canvas Widget that displays the `figure`
        # it takes the `figure` instance as a parameter to __init__
        self.canvas = FigureCanvas(self.figure)

        # this is the Navigation widget
        # it takes the Canvas widget and a parent
        self.toolbar = NavigationToolbar(self.canvas, self)

        # Just some button connected to `plot` method
        self.button = QPushButton('Plot')
        self.button.clicked.connect(self.plot)

if __name__ == '__main__':
    app = QApplication(sys.argv)

    main = Window()
    main.show()

    sys.exit(app.exec_())

if(!response.isSuccessful()) {
    StringBuilder error = new StringBuilder();
    try {
        BufferedReader bufferedReader = null;
        if (response.errorBody() != null) {
            bufferedReader = new BufferedReader(new InputStreamReader(
                    response.errorBody().byteStream()));

            String eLine = null;
            while ((eLine = bufferedReader.readLine()) != null) {
                error.append(eLine);
            }
            bufferedReader.close();
        }

    } catch (Exception e) {
        error.append(e.getMessage());
    }

    Log.e("Error", error.toString());
}

Here is a simple way to understand the concept: The basic idea is, if you want a collection that you can use "foreach" on, but gathering the items into the collection is expensive for some reason (like querying them out of a database), AND you will often not need the entire collection, then you create a function that builds the collection one item at a time and yields it back to the consumer (who can then terminate the collection effort early).

Think of it this way: You go to the meat counter and want to buy a pound of sliced ham. The butcher takes a 10-pound ham to the back, puts it on the slicer machine, slices the whole thing, then brings the pile of slices back to you and measures out a pound of it. (OLD way). With yield, the butcher brings the slicer machine to the counter, and starts slicing and "yielding" each slice onto the scale until it measures 1-pound, then wraps it for you and you're done. The Old Way may be better for the butcher (lets him organize his machinery the way he likes), but the New Way is clearly more efficient in most cases for the consumer.

FYI - none of the above worked for me in 2012 SP1...simple solution was to embed credentials in the shared data source and then tell Safari to trust the SSRS server site. Then it worked great! Took days chasing down supposed solutions like above only to find out integrated security won't work reliably on Safari - you have to mess with the keychain on the mac and then still wouldn't work reliably.

Not sure it applies here also but in the case of protractor when using navigate().to(...) the history is being kept but when using get() it is lost.

One of my test was failing because I was using get() 2 times in a row and then doing a navigate().back(). Because the history was lost, when going back it went to the about page and an error was thrown:

Error: Error while waiting for Protractor to sync with the page: {}

Read a File from resources folder using NIO, in java8

public static String read(String fileName) {

        Path path;
        StringBuilder data = new StringBuilder();
        Stream<String> lines = null;
        try {
            path = Paths.get(Thread.currentThread().getContextClassLoader().getResource(fileName).toURI());
            lines = Files.lines(path);
        } catch (URISyntaxException | IOException e) {
            logger.error("Error in reading propertied file " + e);
            throw new RuntimeException(e);
        }

        lines.forEach(line -> data.append(line));
        lines.close();
        return data.toString();
    }

You need to change the loop from for ($i=1; $i<count($files); $i++) to for ($i=0; $i<count($files); $i++):

So the correct code is

<?php
$files = glob("images/*.*");

for ($i=0; $i<count($files); $i++) {
    $image = $files[$i];
    print $image ."<br />";
    echo '<img src="'.$image .'" alt="Random image" />'."<br /><br />";
}

?>

SRC = a.cpp b.cpp
BIN = $(patsubst %.cpp,%,$(SRC))

all: $(BIN)

clean:
    rm -f $(BIN)

.PHONY: all clean

make all will do:

c++     a.cpp   -o a
c++     b.cpp   -o b

If you set CXX and CXXFLAGS variables make will use them.

an example of a language feature that isn't just removing line breaks, although still not convinced this is clearer than the more verbose version

a = 1 if x > 15 else 2

Yes it is true.

If you create two instance of your class

Test t1 = new Test();
Test t2 = new Test();

Then t1.foo and t2.foo both synchronize on the same static object and hence block each other.

The simple solution, which no one have mentioned yet, is to just ignore the problem. If I try to use an int as a template type in a function template that expects a container class such as vector or list, then I will get a compile error. Crude and simple, but it solves the problem. The compiler will try to use the type you specify, and if that fails, it generates a compile error.

The only problem with that is that the error messages you get are going to be tricky to read. It is nevertheless a very common way to do this. The standard library is full of function or class templates that expect certain behavior from the template type, and do nothing to check that the types used are valid.

If you want nicer error messages (or if you want to catch cases that wouldn't produce a compiler error, but still don't make sense) you can, depending on how complex you want to make it, use either Boost's static assert or the Boost concept_check library.

With an up-to-date compiler you have a built_in static_assert, which could be used instead.

You can achieve almost everything in PROCESS_NUM with this one-liner:

[ `pgrep $1` ] && return 1 || return 0

if you're looking for a partial match, i.e. program is named foobar and you want your $1 to be just foo you can add the -f switch to pgrep:

[[ `pgrep -f $1` ]] && return 1 || return 0

Putting it all together your script could be reworked like this:

#!/bin/bash

check_process() {
  echo "$ts: checking $1"
  [ "$1" = "" ]  && return 0
  [ `pgrep -n $1` ] && return 1 || return 0
}

while [ 1 ]; do 
  # timestamp
  ts=`date +%T`

  echo "$ts: begin checking..."
  check_process "dropbox"
  [ $? -eq 0 ] && echo "$ts: not running, restarting..." && `dropbox start -i > /dev/null`
  sleep 5
done

Running it would look like this:

# SHELL #1
22:07:26: begin checking...
22:07:26: checking dropbox
22:07:31: begin checking...
22:07:31: checking dropbox

# SHELL #2
$ dropbox stop
Dropbox daemon stopped.

# SHELL #1
22:07:36: begin checking...
22:07:36: checking dropbox
22:07:36: not running, restarting...
22:07:42: begin checking...
22:07:42: checking dropbox

Hope this helps!

I found that most solutions didn't work with clicks on elements like Labels or DIV's (eg. when using Kendo controls). So I made this simple solution:

function isDoubleClicked(element) {
    //if already clicked return TRUE to indicate this click is not allowed
    if (element.data("isclicked")) return true;

    //mark as clicked for 1 second
    element.data("isclicked", true);
    setTimeout(function () {
        element.removeData("isclicked");
    }, 1000);

    //return FALSE to indicate this click was allowed
    return false;
}

Use it on the place where you have to decide to start an event or not:

$('#button').on("click", function () {
    if (isDoubleClicked($(this))) return;

    ..continue...
});

Note that SimpleDateFormat format pattern Z is for RFC 822 time zone and pattern X is for ISO 8601 (this standard supports single letter time zone names like Z for Zulu).

So new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSSX") produces a format that can parse both "2013-03-11T01:38:18.309Z" and "2013-03-11T01:38:18.309+0000" and will give you the same result.

Unfortunately, as far as I can tell, you can't get this format to generate the Z for Zulu version, which is annoying.

I actually have more trouble on the JavaScript side to deal with both formats.

You can use until():

LocalDate independenceDay = LocalDate.of(2014, Month.JULY, 4);
LocalDate christmas = LocalDate.of(2014, Month.DECEMBER, 25);

System.out.println("Until christmas: " + independenceDay.until(christmas));
System.out.println("Until christmas (with crono): " + independenceDay.until(christmas, ChronoUnit.DAYS));

Here are a few steps to solve it the no. 4 step is works for me.

1. Delete .log files along .metadata folder.
2. Check the current user permission make sure to check the full control checkbox click apply then OK.
3. If you run system drive defragmentation or maintenance before you run eclipse editor sometimes original file path are not in their respective path to make sure run "previous version" time before your system maintenance of your drive where the eclipse workbench or something similar to this was saved.
4. This last option is works for me. Check the drive letter of your current drive where the code editor was saved. If something unusual e.g before your maintenance your drive letter is K then after defragment or maintenance. The drive letter is now L hence you should change the drive letter to its original one that is K. to do this click the ff: Open control panel System & security Administrative tools Computer management Disk management in disk mngt choose the Drive example L then right click > change drive letter & path > click remove > then ok, open it again then > click add and > choose your original drive letter for that drive then click ok. If you use your computer for a long period of time do restart first to refresh everything.

I do not have a USB serial device, but there must be a way to find the real ports using the HAL libraries directly:

====================================================================
#! /usr/bin/env bash
#
# Uses HAL to find existing serial hardware
#

for sport in $(hal-find-by-capability --capability serial) ; do
  hal-get-property --udi "${sport}" --key serial.device
done

====================================================================

The posted python-dbus code nor this sh script lists the bluetooth /dev/rfcomm* devices, so it is not the best solution.

Note that on other unix platforms, the serial ports are not named ttyS? and even in linux, some serial cards allow you to name the devices. Assuming a pattern in the serial devices names is wrong.

$("span").mouseover(function () {
$(this).css({"background-color":"green","font-size":"20px","color":"red"});
});

<div>
Sachin Tendulkar has been the most complete batsman of his time, the most prolific     runmaker of all time, and arguably the biggest cricket icon the game has ever known. His batting is based on the purest principles: perfect balance, economy of movement, precision in stroke-making.
</div>

In practice, it is possible, if you use span element instead of font:

<style>
u { color: black; }
.red { color: red }
</style>
<u><span class='red'><br>$username</span></u>

See jsfiddle. Appears to work on Chrome, Safari, Firefox, IE, Opera (tested on Win 7 with newest versions).

The code in the question should work, too, but it does not work for some reason on WebKit browsers (Chrome, Safari).

By the CSS spec: “The color(s) required for the text decoration must be derived from the 'color' property value of the element on which 'text-decoration' is set. The color of decorations must remain the same even if descendant elements have different 'color' values.”

I start with the following template, which is derived from numerous printings of Itzik Ben-Gan's routine:

;WITH
  Pass0 as (select 1 as C union all select 1), --2 rows
  Pass1 as (select 1 as C from Pass0 as A, Pass0 as B),--4 rows
  Pass2 as (select 1 as C from Pass1 as A, Pass1 as B),--16 rows
  Pass3 as (select 1 as C from Pass2 as A, Pass2 as B),--256 rows
  Pass4 as (select 1 as C from Pass3 as A, Pass3 as B),--65536 rows
  Pass5 as (select 1 as C from Pass4 as A, Pass4 as B),--4,294,967,296 rows
  Tally as (select row_number() over(order by C) as Number from Pass5)
 select Number from Tally where Number <= 1000000

The "WHERE N<= 1000000" clause limits the output to 1 to 1 million, and can easily be adjusted to your desired range.

Since this is a WITH clause, it can be worked into an INSERT... SELECT... like so:

--  Sample use: create one million rows

Indexing the table after it's built will be the fastest way to index it.

Oh, and I'd refer to it as a "Tally" table. I think this is a common term, and you can find loads of tricks and examples by Googling it.

Here's a method that worked for me. When you type into the field, it puts that text into the hidden span, then gets its new width and applies it to the input field. It grows and shrinks with your input, with a safeguard against the input virtually disappearing when you erase all input. Tested in Chrome. (EDIT: works in Safari, Firefox and Edge at the time of this edit)

public FileContentResult GetImage(int productId) { 
     Product prod = repository.Products.FirstOrDefault(p => p.ProductID == productId);

         return File(prod.ImageData, prod.ImageMimeType); 
      } else { 
         return null; 
     } 
}

You Can Now Delete App.

On October 4, 2018, Apple released a new update of the appstoreconnect (previously iTunesConnect).

It's now easier to manage apps you no longer need in App Store Connect by removing them from your main view in My Apps, even if they haven't been submitted for approval. You must have the Legal or Admin role to remove apps.

From the homepage, click My Apps, then choose the app you want to remove. Scroll to the Additional Information section, then click Remove App. In the dialog that appears, click Remove. You can restore a removed app at any time, as long as the app name is not currently in use by another developer.

From the homepage, click My Apps. In the upper right-hand corner, click the arrow next to All Statuses. From the drop-down menu, choose Removed Apps. Choose the app you want to restore. Scroll to the Additional Information section, then click Restore App.

You can show the removed app by clicking on all Statuses on the top right of the screen and then select Removed Apps. Thank you @Daniel for the tips.

Please note:

you can only remove apps if all versions of that app are in one of the following states: Prepare for Submission, Invalid Binary, Developer Rejected, Rejected, Metadata Rejected, Developer, Removed from Sale.

For mongoDB database restore use this command here . First go to your mongodb database location such as For Example : cd Downloads/blank_db/v34000 After that Enter mongorestore -d v34000 ./

The two previous answers demonstrate how to use Canvas and ImageData. I would like to propose an answer with runnable example and using an image processing framework, so you don't need to handle the pixel data manually.

MarvinJ provides the method image.getAlphaComponent(x,y) which simply returns the transparency value for the pixel in x,y coordinate. If this value is 0, pixel is totally transparent, values between 1 and 254 are transparency levels, finally 255 is opaque.

For demonstrating I've used the image below (300x300) with transparent background and two pixels at coordinates (0,0) and (150,150).

Console output:

(0,0): TRANSPARENT
(150,150): NOT_TRANSPARENT

image = new MarvinImage();_x000D_
image.load("https://i.imgur.com/eLZVbQG.png", imageLoaded);_x000D_
_x000D_
function imageLoaded(){_x000D_
  console.log("(0,0): "+(image.getAlphaComponent(0,0) > 0 ? "NOT_TRANSPARENT" : "TRANSPARENT"));_x000D_
  console.log("(150,150): "+(image.getAlphaComponent(150,150) > 0 ? "NOT_TRANSPARENT" : "TRANSPARENT"));_x000D_
}

TO_DATE supports conversion to DATE datatype, which doesn't support milliseconds. If you want millisecond support in Oracle, you should look at TIMESTAMP datatype and TO_TIMESTAMP function.

Hope that helps.

As commented in @Benson answer, I used this example in my code and I found it very useful. However I found with the Object is possibly 'undefined'.ts(2532) error when I tried to make calculations with my class variable types, as the question mark leads them to be of type AssignedType | undefined. Even if undefined case is handled in later execution or with the compiler type enforce <AssignedType> I could not get rid of the error, so could not make the args optional.I solved creating a separated type for the arguments with the question mark params and the class variables without the question marks. Verbose, but worked.

Here is the original code, giving the error in the class method(), see below:

/** @class */

class Box {
  public x?: number;
  public y?: number;
  public height?: number;
  public width?: number;

  // The Box class can work double-duty as the interface here since they are identical
  // If you choose to add methods or modify this class, you will need to
  // define and reference a new interface for the incoming parameters object 
  // e.g.:  `constructor(params: BoxObjI = {} as BoxObjI)` 
  constructor(params: Box = {} as Box) {
    // Define the properties of the incoming `params` object here. 
    // Setting a default value with the `= 0` syntax is optional for each parameter
    const {
      x = 0,
      y = 0,
      height = 1,
      width = 1,
    } = params;

    //  If needed, make the parameters publicly accessible
    //  on the class ex.: 'this.var = var'.
    /**  Use jsdoc comments here for inline ide auto-documentation */
    this.x = x;
    this.y = y;
    this.height = height;
    this.width = width;
  }

  method(): void {
    const total = this.x + 1; // ERROR. Object is possibly 'undefined'.ts(2532)
  }
}

const box1 = new Box();
const box2 = new Box({});
const box3 = new Box({ x: 0 });
const box4 = new Box({ x: 0, height: 10 });
const box5 = new Box({ x: 0, y: 87, width: 4, height: 0 });

So variable cannot be used in the class methods. If that is corrected like this for example:

method(): void {
    const total = <number> this.x + 1;
}

Now this error appears:

Argument of type '{ x: number; y: number; width: number; height: number; }' is not 
assignable to parameter of type 'Box'.
Property 'method' is missing in type '{ x: number; y: number; width: number; height: 
number; }' but required in type 'Box'.ts(2345)

As if the whole arguments bundle was no optional anymore.

So if a type with optional args is created, and the class variables are removed from optional I achieve what I want, the arguments to be optional, and to be able to use them in the class methods. Below the solution code:

type BoxParams = {
  x?: number;
  y?: number;
  height?: number;
  width?: number;
}

/** @class */
class Box {
  public x: number;
  public y: number;
  public height: number;
  public width: number;

  // The Box class can work double-duty as the interface here since they are identical
  // If you choose to add methods or modify this class, you will need to
  // define and reference a new interface for the incoming parameters object 
  // e.g.:  `constructor(params: BoxObjI = {} as BoxObjI)` 
  constructor(params: BoxParams = {} as BoxParams) {
    // Define the properties of the incoming `params` object here. 
    // Setting a default value with the `= 0` syntax is optional for each parameter
    const {
      x = 0,
      y = 0,
      height = 1,
      width = 1,
    } = params;

    //  If needed, make the parameters publicly accessible
    //  on the class ex.: 'this.var = var'.
    /**  Use jsdoc comments here for inline ide auto-documentation */
    this.x = x;
    this.y = y;
    this.height = height;
    this.width = width;
  }

  method(): void {
    const total = this.x + 1;
  }
}

const box1 = new Box();
const box2 = new Box({});
const box3 = new Box({ x: 0 });
const box4 = new Box({ x: 0, height: 10 });
const box5 = new Box({ x: 0, y: 87, width: 4, height: 0 });

Comments appreciated from anyone who takes the time to read and try to understand the point I am trying to make.

Thanks in advance.

There are no build in function for it. You can find the GCD of two numbers using Euclid's algorithm.

For a set of number

GCD(a_1,a_2,a_3,...,a_n) = GCD( GCD(a_1, a_2), a_3, a_4,..., a_n )

Apply it recursively.

Same for LCM:

LCM(a,b) = a * b / GCD(a,b)
LCM(a_1,a_2,a_3,...,a_n) = LCM( LCM(a_1, a_2), a_3, a_4,..., a_n )

Why do we need to differentiate between POD's and non-POD's at all?

C++ started its life as an extension of C. While modern C++ is no longer a strict superset of C, people still expect a high level of compatibility between the two. The "C ABI" of a platform also frequently acts as a de-facto standard inter-language ABI for other languages on the platform.

Roughly speaking, a POD type is a type that is compatible with C and perhaps equally importantly is compatible with certain ABI optimisations.

To be compatible with C, we need to satisfy two constraints.

1. The layout must be the same as the corresponding C type.
2. The type must be passed to and returned from functions in the same way as the corresponding C type.

Certain C++ features are incompatible with this.

Virtual methods require the compiler to insert one or more pointers to virtual method tables, something that doesn't exist in C.

User-defined copy constructors, move constructors, copy assignments and destructors have implications for parameter passing and returning. Many C ABIs pass and return small parameters in registers, but the references passed to the user defined constructor/assigment/destructor can only work with memory locations.

So there is a need to define what types can be expected to be "C compatible" and what types cannot. C++03 was somewhat over-strict in this regard, any user-defined constructor would disable the built-in constructors and any attempt to add them back in would result in them being user-defined and hence the type being non-pod. C++11 opened things up quite a bit, by allowing the user to re-introduce the built-in constructors.

Here is a simple example. I suppose it will be easy to understand:

import java.awt.*;
import javax.swing.JFrame;
import javax.swing.JPanel;

public class Graph extends JFrame {
JFrame f = new JFrame();
JPanel jp;


public Graph() {
    f.setTitle("Simple Drawing");
    f.setSize(300, 300);
    f.setDefaultCloseOperation(EXIT_ON_CLOSE);

    jp = new GPanel();
    f.add(jp);
    f.setVisible(true);
}

public static void main(String[] args) {
    Graph g1 = new Graph();
    g1.setVisible(true);
}

class GPanel extends JPanel {
    public GPanel() {
        f.setPreferredSize(new Dimension(300, 300));
    }

    @Override
    public void paintComponent(Graphics g) {
        //rectangle originates at 10,10 and ends at 240,240
        g.drawRect(10, 10, 240, 240);
        //filled Rectangle with rounded corners.    
        g.fillRoundRect(50, 50, 100, 100, 80, 80);
    }
}

}

And the output looks like this:

Here's a fix to invoketheshell's buggy code (which currently appears as the accepted answer):

def performance_measure(y_actual, y_hat):
    TP = 0
    FP = 0
    TN = 0
    FN = 0

    for i in range(len(y_hat)): 
        if y_actual[i] == y_hat[i]==1:
            TP += 1
        if y_hat[i] == 1 and y_actual[i] == 0:
            FP += 1
        if y_hat[i] == y_actual[i] == 0:
            TN +=1
        if y_hat[i] == 0 and y_actual[i] == 1:
            FN +=1

    return(TP, FP, TN, FN)

Here's a response to your latest question about the difference between x86_64 and arm64:

• x86_64 architecture is required for running the 64bit simulator.

• arm64 architecture is required for running the 64bit device (iPhone 5s, iPhone 6, iPhone 6 Plus, iPad Air, iPad mini with Retina display).

Windows Firewall was creating this error for me. SMTP was trying to post to GMAIL at port 587. Adding port 587 to the Outbound rule [Outbound HTTP/SMTP/RDP] resolved the issue.

Use this

    Dialog dialog = new Dialog(getActivity());
    dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
    dialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
    dialog.setCancelable(true);
    dialog.setContentView(R.layout.image_show_dialog_layout);

The outfile should be in binary mode.

outFile = open('output.xml', 'wb')

IF(compliment IN('set','Y',1), 'Y', 'N') AS customer_compliment

Will do the job as Buttle Butkus suggested.

Nope, definitely not.

If you use a decent JSON serializer, it won't let you serialize a function like that. It's a valid OBJECT, but not valid JSON. Whatever that website's intent, it's not sending valid JSON.

DateTime.Now.ToString("h:mm tt")
DateTime.Now.ToString("MM/dd/yyyy")

Here are some common format strings

You can use e.preventDefault(); instead of e.stopPropagation();

Tested on Ideone.

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

Having hit this one a few times and followed a bunch of suggestions, if you don't find it available after installing the NuGet Microsoft.AspNet.WebApi.Client manually add a reference from the packages folder in the solution to:

\Microsoft.AspNet.WebApi.Client.5.2.6\lib\net45\System.Net.Http.Formatting.dll

And don't get into the trap of adding older references to the System.Net.Http.Formatting.dll NuGet

Use pd.to_numeric with errors='coerce'

# Setup
s = pd.Series(['1', '2', '3', '4', '.'])
s

0    1
1    2
2    3
3    4
4    .
dtype: object

pd.to_numeric(s, errors='coerce')

0    1.0
1    2.0
2    3.0
3    4.0
4    NaN
dtype: float64

If you need the NaNs filled in, use Series.fillna.

pd.to_numeric(s, errors='coerce').fillna(0, downcast='infer')

0    1
1    2
2    3
3    4
4    0
dtype: float64

Note, downcast='infer' will attempt to downcast floats to integers where possible. Remove the argument if you don't want that.

From v0.24+, pandas introduces a Nullable Integer type, which allows integers to coexist with NaNs. If you have integers in your column, you can use

pd.__version__
# '0.24.1'

pd.to_numeric(s, errors='coerce').astype('Int32')

0      1
1      2
2      3
3      4
4    NaN
dtype: Int32

There are other options to choose from as well, read the docs for more.

Extension for DataFrames

If you need to extend this to DataFrames, you will need to apply it to each row. You can do this using DataFrame.apply.

# Setup.
np.random.seed(0)
df = pd.DataFrame({
    'A' : np.random.choice(10, 5), 
    'C' : np.random.choice(10, 5), 
    'B' : ['1', '###', '...', 50, '234'], 
    'D' : ['23', '1', '...', '268', '$$']}
)[list('ABCD')]
df

   A    B  C    D
0  5    1  9   23
1  0  ###  3    1
2  3  ...  5  ...
3  3   50  2  268
4  7  234  4   $$

df.dtypes

A     int64
B    object
C     int64
D    object
dtype: object

df2 = df.apply(pd.to_numeric, errors='coerce')
df2

   A      B  C      D
0  5    1.0  9   23.0
1  0    NaN  3    1.0
2  3    NaN  5    NaN
3  3   50.0  2  268.0
4  7  234.0  4    NaN

df2.dtypes

A      int64
B    float64
C      int64
D    float64
dtype: object

You can also do this with DataFrame.transform; although my tests indicate this is marginally slower:

df.transform(pd.to_numeric, errors='coerce')

   A      B  C      D
0  5    1.0  9   23.0
1  0    NaN  3    1.0
2  3    NaN  5    NaN
3  3   50.0  2  268.0
4  7  234.0  4    NaN

If you have many columns (numeric; non-numeric), you can make this a little more performant by applying pd.to_numeric on the non-numeric columns only.

df.dtypes.eq(object)

A    False
B     True
C    False
D     True
dtype: bool

cols = df.columns[df.dtypes.eq(object)]
# Actually, `cols` can be any list of columns you need to convert.
cols
# Index(['B', 'D'], dtype='object')

df[cols] = df[cols].apply(pd.to_numeric, errors='coerce')
# Alternatively,
# for c in cols:
#     df[c] = pd.to_numeric(df[c], errors='coerce')

df

   A      B  C      D
0  5    1.0  9   23.0
1  0    NaN  3    1.0
2  3    NaN  5    NaN
3  3   50.0  2  268.0
4  7  234.0  4    NaN

Applying pd.to_numeric along the columns (i.e., axis=0, the default) should be slightly faster for long DataFrames.

When using the new ruby, the image folder will go to asset folder on folder app

after placing your images in image folder, use

<%=image_tag("example_image.png", alt: "Example Image")%>

This can also be achieved with itertools.chain.from_iterable which will flatten the consecutive iterables:

import itertools
for item in itertools.chain.from_iterable(iterables):
    # do something with item    

1-Right click on Android Studio and click on properties.

2-Replace studio64.exe in link by studio.exe.

In my case the problem was that https was unable to start correctly because Listen 443 was in "IfDefine SSL" derective, but my apache didnt start with -DSSL option. The fix was to change my apachectl script in:

$HTTPD -k $ARGV

to:

$HTTPD -k $ARGV -DSSL

Hope that helps somebody.

textBox1.Background = Brushes.Blue;
textBox1.Foreground = Brushes.Yellow;

WPF Foreground and Background is of type System.Windows.Media.Brush. You can set another color like this:

using System.Windows.Media;

textBox1.Background = Brushes.White;
textBox1.Background = new SolidColorBrush(Colors.White);
textBox1.Background = new SolidColorBrush(Color.FromArgb(0xFF, 0xFF, 0, 0));
textBox1.Background = System.Windows.SystemColors.MenuHighlightBrush;

You can use s3cmd to download your bucket:

s3cmd --configure
s3cmd sync s3://bucketnamehere/folder /destination/folder

There is another tool you can use called rclone. This is a code sample in the Rclone documentation:

rclone sync /home/local/directory remote:bucket

Use

@Before("execution(* (@YourAnnotationAtClassLevel *).*(..))")
    public void beforeYourAnnotation(JoinPoint proceedingJoinPoint) throws Throwable {

Use this syntax for VB.NET 2005/2008 compatibility:

Dim theVar As New List(Of String)(New String() {"one", "two", "three"})

Although the VB.NET 2010 syntax is prettier.

Update using a random generated public key.

Encypt:

openssl enc -aes-256-cbc -a -salt -in {raw data} -out {encrypted data} -pass file:{random key}

Decrypt:

openssl enc -d -aes-256-cbc -in {ciphered data} -out {raw data}

Okay, so if you're on the same boat as me and found that none of these solutions helped you, you most likely have a problem where NuGet (or any of those packages) is failing to install from the VSIX program due it calling a method that doesn't exist on your computer (not sure what .dll it's referencing), so try this out from the following post:

• Delete all instances of Visual Studio 2015- this includes all registry values.
• Install a version of Visual Studio older than Update 1 (RTM version.); this is available here.
• If you still get an error, try repairing just the Visual Studio 2015 program. This is what ultimately fixed it for me.

Hope this helped someone out. It's really frustrating that the installer's log file doesn't help at all. I had to look at the log file specific to NuGet, and that's where I noticed the error:

The installation was unable to install the extension to all the selected products. For more information, click on the install log link at the bottom of the dialog.

Method not found: 'System.Collections.Generic.IEnumerable`1 System.Security.Cryptography.X509Certificates.X509ChainStatus Microsoft.VisualStudio.ExtensionManager.IInstallableExtension.get_InvalidCertificateInformation()'.

If a vector has N elements, there are N+1 possible answers for find. std::find and std::find_if return an iterator to the found element OR end() if no element is found. To change the code as little as possible, your find function should return the equivalent position:

size_t find( const vector<type>& where, int searchParameter )
{
   for( size_t i = 0; i < where.size(); i++ ) {
       if( conditionMet( where[i], searchParameter ) ) {
           return i;
       }
    }
    return where.size();
}
// caller:
const int position = find( firstVector, parameter );
if( position != secondVector.size() ) {
    doAction( secondVector[position] );
}

I would still use std::find_if, though.

Here is what you can do:-

Exim SSL certificates

By default, the /etc/exim.conf will use the cert/key files:

/etc/exim.cert
/etc/exim.key

so if you're wondering where to set your files, that's where.

They're controlled by the exim.conf's options:

tls_certificate = /etc/exim.cert
tls_privatekey = /etc/exim.key

Intermediate Certificates

If you have a CA Root certificate (ca bundle, chain, etc.) you'll add the contents of your CA into the exim.cert, after your actual certificate.

Probably a good idea to make sure you have a copy of everything elsewhere in case you make an error.

Dovecot and ProFtpd should also read it correctly, so dovecot no longer needs the ssl_ca option. So for both cases, there is no need to make any changes to either the exim.conf or dovecot.conf(/etc/dovecot/conf/ssl.conf)

Swift 5.1 • iOS 13

You can use RelativeDateFormatter that has been introduced by Apple in iOS 13.

let exampleDate = Date().addingTimeInterval(-15000)

let formatter = RelativeDateTimeFormatter()
formatter.unitsStyle = .full
let relativeDate = formatter.localizedString(for: exampleDate, relativeTo: Date())

print(relativeDate) // 4 hours ago

See How to show a relative date and time using RelativeDateTimeFormatter.

in a single try catch block you can do all the thing the best practice is to catch the error in different catch block if you want them to show with their own message for particular errors.

I had a similar problem. To solve this (instead of calculate the iframe's height using the body, document or window) I created a div that wraps the whole page content (a div with an id="page" for example) and then I used its height.

What you are looking for is the wait method.

android:backgroundTintMode

Blending mode used to apply the background tint.

android:backgroundTint

Tint to apply to the background. Must be a color value, in the form of #rgb, #argb, #rrggbb, or #aarrggbb.

This may also be a reference to a resource (in the form "@[package:]type:name") or theme attribute (in the form "?[package:][type:]name") containing a value of this type.

I used this solution so that I could keep the invocation of the segue and the data communication within the same function:

private var segueCompletion : ((UIStoryboardSegue, Any?) -> Void)?

func performSegue(withIdentifier identifier: String, sender: Any?, completion: @escaping (UIStoryboardSegue, Any?) -> Void) {
    self.segueCompletion = completion;
    self.performSegue(withIdentifier: identifier, sender: sender);
    self.segueCompletion = nil
}

override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
    self.segueCompletion?(segue, sender)
}

A use case would be something like:

func showData(id : Int){
    someService.loadSomeData(id: id) {
        data in
        self.performSegue(withIdentifier: "showData", sender: self) {
            storyboard, sender in
            let dataView = storyboard.destination as! DataView
            dataView.data = data
        }
    }
}

This seems to work for me, however, I'm not 100% sure that the perform and prepare functions are always executed on the same thread.

The following code can be compiled and runs properly, using MinGW G++ 3.4.5 on Window 7:

#include <iostream>
#include <string>

using namespace std;

template <typename T>
class A{
public:
    virtual void func1(const T& p)
    {
        cout<<"A:"<<p<<endl;
    }
};

template <typename T>
class B
: public A<T>
{
public:
    virtual void func1(const T& p)
    {
        cout<<"A<--B:"<<p<<endl;
    }
};

int main(int argc, char** argv)
{
    A<string> a;
    B<int> b;
    B<string> c;

    A<string>* p = &a;
    p->func1("A<string> a");
    p = dynamic_cast<A<string>*>(&c);
    p->func1("B<string> c");
    B<int>* q = &b;
    q->func1(3);
}

and the output is:

A:A<string> a
A<--B:B<string> c
A<--B:3

And later I added a new class X:

class X
{
public:
    template <typename T>
    virtual void func2(const T& p)
    {
        cout<<"C:"<<p<<endl;
    }
};

When I tried to use class X in main() like this:

X x;
x.func2<string>("X x");

g++ report the following error:

vtempl.cpp:34: error: invalid use of `virtual' in template declaration of `virtu
al void X::func2(const T&)'

So it is obvious that:

• virtual member function can be used in a class template. It is easy for compiler to construct vtable
• It is impossible to define a class template member function as virtual, as you can see, it hard to determine function signature and allocate vtable entries.

It switches back because by default, when you click a link, it follows the link and loads the page. In your case, you don't want that. You can prevent it either by doing e.preventDefault(); (like Neal mentioned) or by returning false :

$(function() {
 $('.menulink').click(function(){
   $("#bg").attr('src',"img/picture1.jpg");
   return false;
 });
});

Interesting question on the differences between prevent default and return false.

In this case, return false will work just fine because the event doesn't need to be propagated.

I know it is not a good habit to answer an old question but I'm putting this answer for people who would see the question afterwards.

The best way to change the state in JQuery now is through

$("#input").prop('disabled', true); 
$("#input").prop('disabled', false);

Please check this link for full illustration. Disable/enable an input with jQuery?

You could do something like this:

$("#txtArea").on("keypress",function(e) {_x000D_
    var key = e.keyCode;_x000D_
_x000D_
    // If the user has pressed enter_x000D_
    if (key == 13) {_x000D_
        document.getElementById("txtArea").value =document.getElementById("txtArea").value + "\n";_x000D_
        return false;_x000D_
    }_x000D_
    else {_x000D_
        return true;_x000D_
    }_x000D_
});

<textarea id="txtArea"></textarea>

+1 on S.Lott's suggestion of a named container class.

For Python 2.6 and up, a named tuple provides a useful way of easily creating these container classes, and the results are "lightweight and require no more memory than regular tuples".

Remove ~ character in location so

path="~/Admin/SomePage.aspx"

becomes

path="Admin/SomePage.aspx"

You can use this code:

int count;
            try {
                URL url = new URL(f_url[0]);
                URLConnection conection = url.openConnection();
                conection.setConnectTimeout(TIME_OUT);
                conection.connect();
                // Getting file length
                int lenghtOfFile = conection.getContentLength();
                // Create a Input stream to read file - with 8k buffer
                InputStream input = new BufferedInputStream(url.openStream(),
                        8192);
                // Output stream to write file
                OutputStream output = new FileOutputStream(
                        "/sdcard/9androidnet.jpg");

                byte data[] = new byte[1024];
                long total = 0;
                while ((count = input.read(data)) != -1) {
                    total += count;
                    // publishing the progress....
                    // After this onProgressUpdate will be called
                    publishProgress("" + (int) ((total * 100) / lenghtOfFile));
                    // writing data to file
                    output.write(data, 0, count);
                }
                // flushing output
                output.flush();
                // closing streams
                output.close();
                input.close();
            } catch (SocketTimeoutException e) {
                connectionTimeout=true;
            } catch (Exception e) {
                Log.e("Error: ", e.getMessage());
            }

My guess: Because Twitter sees the need to support legacy browsers, otherwise they would be using the :before / :after pseudo-elements.

Legacy browsers don't support those pseudo-elements I mentioned, so they need to use an actual HTML element for the icons, and since icons don't have an 'exclusive' tag, they just went with the <i> tag, and all browsers support that tag.

They could've certainly used a <span>, just like you are (which is TOTALLY fine), but probably for the reason I mentioned above plus the ones mentioned by Quentin, is also why Bootstrap is using the <i> tag.

It's a bad practice when you use extra markup for styling reasons, that's why pseudo-elements were invented, to separate content from style... but when you see the need to support legacy browsers, sometimes you're forced to do these kind of things.

PS. The fact that icons start with an 'i' and that there's an <i> tag, is completely coincidental.

The below code worked for me for any type of cell.

InputStream inp =getClass().getResourceAsStream("filename.xls"));
Workbook wb = WorkbookFactory.create(inp);
DataFormatter objDefaultFormat = new DataFormatter();
FormulaEvaluator objFormulaEvaluator = new HSSFFormulaEvaluator((HSSFWorkbook) wb);

Sheet sheet= wb.getSheetAt(0);
Iterator<Row> objIterator = sheet.rowIterator();

while(objIterator.hasNext()){

    Row row = objIterator.next();
    Cell cellValue = row.getCell(0);
    objFormulaEvaluator.evaluate(cellValue); // This will evaluate the cell, And any type of cell will return string value
    String cellValueStr = objDefaultFormat.formatCellValue(cellValue,objFormulaEvaluator);

}

If I remember well, I had the same kind of issue when loading stuff from the asset folder but with a database. It seems that the stuff in your asset folder can have 2 stats : compressed or not.
If it is compressed, then you are allowed 1 Mo of memory to uncompress it, otherwise you will get this kind of exception. There are several bug reports about that because the documentation is not clear. So if you still want to to use your format, you have to either use an uncompressed version, or give an extension like .mp3 or .png to your file. I know it's a bit crazy but I load a database with a .mp3 extension and it works perfectly fine. This other solution is to package your application with a special option to tell it not to compress certain extension. But then you need to build your app manually and add "zip -0" option.
The advantage of an uncompressed assest is that the phase of zip-align before publication of an application will align the data correctly so that when loaded in memory it can be directly mapped.

So, solutions :

• change the extension of the file to .mp3 or .png and see if it works
• build your app manually and use the zip-0 option

If you want deep validation like @speculees, here's an answer using deep-keys (disclosure: I'm sort of a maintainer of this small package)

// obj1 should have all of obj2's properties
var deepKeys = require('deep-keys');
var _ = require('underscore');
assert(0 === _.difference(deepKeys(obj2), deepKeys(obj1)).length);

// obj1 should have exactly obj2's properties
var deepKeys = require('deep-keys');
var _ = require('lodash');
assert(0 === _.xor(deepKeys(obj2), deepKeys(obj1)).length);

or with chai:

var expect = require('chai').expect;
var deepKeys = require('deep-keys');
// obj1 should have all of obj2's properties
expect(deepKeys(obj1)).to.include.members(deepKeys(obj2));
// obj1 should have exactly obj2's properties
expect(deepKeys(obj1)).to.have.members(deepKeys(obj2));

Just use parseInt() and be sure to include the radix so you get predictable results:

parseInt(d, 10);

It works in a different way for variables copied by reference:

$a = 5;
$b = &$a;
unset($b); // just say $b should not point to any variable
print $a; // 5

$a = 5;
$b = &$a;
$b = null; // rewrites value of $b (and $a)
print $a; // nothing, because $a = null

mycrypt.o and mcrypt_filter.o are in the ext/.libs of your php downloaded directory. Just copy the files to ext/mcrypt, then run make && make install again.

Use \nolinebreak

\nolinebreak[number]

The \nolinebreak command prevents LaTeX from breaking the current line at the point of the command. With the optional argument, number, you can convert the \nolinebreak command from a demand to a request. The number must be a number from 0 to 4. The higher the number, the more insistent the request is.

Source: http://www.personal.ceu.hu/tex/breaking.htm#nolinebreak

You can control select all customised classes and methods, and right-click, choose "Source", then select "Generate Element Comment". You should get what you want.

If you want to modify the Code Template then you can go to Preferences -- Java -- Code Style -- Code Templates, then do whatever you want.

Suppose you have the following code:

import java.util.Map;
import java.util.concurrent.ConcurrentHashMap;

public class Test {
    public static void main(String[] s) {
        Map<String, Boolean> whoLetDogsOut = new ConcurrentHashMap<>();
        whoLetDogsOut.computeIfAbsent("snoop", k -> f(k));
        whoLetDogsOut.computeIfAbsent("snoop", k -> f(k));
    }
    static boolean f(String s) {
        System.out.println("creating a value for \""+s+'"');
        return s.isEmpty();
    }
}

Then you will see the message creating a value for "snoop" exactly once as on the second invocation of computeIfAbsent there is already a value for that key. The k in the lambda expression k -> f(k) is just a placeolder (parameter) for the key which the map will pass to your lambda for computing the value. So in the example the key is passed to the function invocation.

Alternatively you could write: whoLetDogsOut.computeIfAbsent("snoop", k -> k.isEmpty()); to achieve the same result without a helper method (but you won’t see the debugging output then). And even simpler, as it is a simple delegation to an existing method you could write: whoLetDogsOut.computeIfAbsent("snoop", String::isEmpty); This delegation does not need any parameters to be written.

To be closer to the example in your question, you could write it as whoLetDogsOut.computeIfAbsent("snoop", key -> tryToLetOut(key)); (it doesn’t matter whether you name the parameter k or key). Or write it as whoLetDogsOut.computeIfAbsent("snoop", MyClass::tryToLetOut); if tryToLetOut is static or whoLetDogsOut.computeIfAbsent("snoop", this::tryToLetOut); if tryToLetOut is an instance method.

Simple:

[1,2,3].map(x => [x, x * 10])
// [[1, 10], [2, 20], [3, 30]]

[1,2,3].flatMap(x => [x, x * 10])
// [1, 10, 2, 20, 3, 30]]

Bootstrap 4 define a CSS style for the HTML built-in horizontal divider <hr />, so just use it.

You can also customize margin with spacing utilities: mt for margin top, mb for margin bottom and my for margin top and bottom. The integer represent spacing 1 for small margin and 5 for huge margin. Here is an example:

<hr class="mt-2 mb-3"/>
<!-- OR -->
<hr class="my-3"/>
<!-- It's like -->
<hr class="mt-3 mb-3"/>

I used to be using just a div with border-top like:

<div class="border-top my-3"></div>

but it's a silly method to make the work done, and you can have some issues. So just use <hr />.

Be aware that passing an Object with named properties as Ken suggested adds the cost of allocating and releasing the temporary object to every call. Passing normal arguments by value or reference will generally be the most efficient. For many applications though the performance is not critical but for some it can be.

"use strict";

var constants = Object.freeze({
    "p": 3.141592653589793 ,
    "e": 2.718281828459045 ,
    "i": Math.sqrt(-1)
});

constants.p;        // -> 3.141592653589793
constants.p = 3;    // -> TypeError: Cannot assign to read only property 'p' …
constants.p;        // -> 3.141592653589793

delete constants.p; // -> TypeError: Unable to delete property.
constants.p;        // -> 3.141592653589793

See Object.freeze. You can use const if you want to make the constants reference read-only as well.

UPDATE: for your updated question

variable.match(/\[[0-9]+\]/);

Try this:

variable.match(/[0-9]+/);    // for unsigned integers
variable.match(/[-0-9]+/);   // for signed integers
variable.match(/[-.0-9]+/);  // for signed float numbers

Hope this helps!

Sequence of numbers between 1 and 100.000:

SELECT e*10000+d*1000+c*100+b*10+a n FROM
(select 0 a union all select 1 union all select 2 union all select 3 union all select 4 union all select 5 union all select 6 union all select 7 union all select 8 union all select 9) t1,
(select 0 b union all select 1 union all select 2 union all select 3 union all select 4 union all select 5 union all select 6 union all select 7 union all select 8 union all select 9) t2,
(select 0 c union all select 1 union all select 2 union all select 3 union all select 4 union all select 5 union all select 6 union all select 7 union all select 8 union all select 9) t3,
(select 0 d union all select 1 union all select 2 union all select 3 union all select 4 union all select 5 union all select 6 union all select 7 union all select 8 union all select 9) t4,
(select 0 e union all select 1 union all select 2 union all select 3 union all select 4 union all select 5 union all select 6 union all select 7 union all select 8 union all select 9) t5
order by 1

I use it to audit if some number is out of sequence, something like this:

select * from (
    select 121 id
    union all select 123
    union all select 125
    union all select 126
    union all select 127
    union all select 128
    union all select 129
) a
right join (
    SELECT e*10000+d*1000+c*100+b*10+a n FROM
    (select 0 a union all select 1 union all select 2 union all select 3 union all select 4 union all select 5 union all select 6 union all select 7 union all select 8 union all select 9) t1,
    (select 0 b union all select 1 union all select 2 union all select 3 union all select 4 union all select 5 union all select 6 union all select 7 union all select 8 union all select 9) t2,
    (select 0 c union all select 1 union all select 2 union all select 3 union all select 4 union all select 5 union all select 6 union all select 7 union all select 8 union all select 9) t3,
    (select 0 d union all select 1 union all select 2 union all select 3 union all select 4 union all select 5 union all select 6 union all select 7 union all select 8 union all select 9) t4,
    (select 0 e union all select 1 union all select 2 union all select 3 union all select 4 union all select 5 union all select 6 union all select 7 union all select 8 union all select 9) t5
    order by 1
) seq on seq.n=a.id
where seq.n between 121 and 129
and   id is null

The result will be the gap of number 122 and 124 of sequence between 121 and 129:

id     n
----   ---
null   122
null   124

Maybe it helps someone!

The second is preferred because it is far less likely to result in an accidental cross join by forgetting to put inthe where clause. A join with no on clause will fail the syntax check, an old style join with no where clause will not fail, it will do a cross join.

Additionally when you later have to a left join, it is helpful for maintenance that they all be in the same structure. And the old syntax has been out of date since 1992, it is well past time to stop using it.

Plus I have found that many people who exclusively use the first syntax don't really understand joins and understanding joins is critical to getting correct results when querying.

I add double backslash to the dot to make it work. Cheer.

var st = "okay.this.is.a.string";
var Re = new RegExp("\\.","g");
st = st.replace(Re," ");
alert(st);

You can wrap your query in another SELECT:

select count(*)
from
(
  select count(SID) tot  -- add alias
  from Test 
  where Date = '2012-12-10' 
  group by SID
) src;  -- add alias

See SQL Fiddle with Demo

In order for it to work, the count(SID) need a column alias and you have to provide an alias to the subquery itself.

Use MutationObserver as seen in this snippet provided by Mozilla, and adapted from this blog post

Alternatively, you can use the JQuery example seen in this link

Chrome 18+, Firefox 14+, IE 11+, Safari 6+

// Select the node that will be observed for mutations
var targetNode = document.getElementById('some-id');

// Options for the observer (which mutations to observe)
var config = { attributes: true, childList: true };

// Callback function to execute when mutations are observed
var callback = function(mutationsList) {
    for(var mutation of mutationsList) {
        if (mutation.type == 'childList') {
            console.log('A child node has been added or removed.');
        }
        else if (mutation.type == 'attributes') {
            console.log('The ' + mutation.attributeName + ' attribute was modified.');
        }
    }
};

// Create an observer instance linked to the callback function
var observer = new MutationObserver(callback);

// Start observing the target node for configured mutations
observer.observe(targetNode, config);

// Later, you can stop observing
observer.disconnect();

The other answers are outdated. The behavior of Chrome for window.open depends on where it is called from. See also this topic.

When window.open is called from a handler that was triggered though a user action (e.g. onclick event), it will behave similar as <a target="_blank">, which by default opens in a new tab. However if window.open is called elsewhere, Chrome ignores other arguments and always opens a new window with a non-editable address bar.

This looks like some kind of security measure, although the rationale behind it is not completely clear.

There is timeline.sty floating around.

The syntax is simpler than using tikz:

%%% In LaTeX:
%%% \begin{timeline}{length}(start,stop)
%%%   .
%%%   .
%%%   .
%%% \end{timeline}
%%%
%%% in plain TeX
%%% \timeline{length}(start,stop)
%%%   .
%%%   .
%%%   .
%%% \endtimeline
%%% in between the two, we may have:
%%% \item{date}{description}
%%% \item[sortkey]{date}{description}
%%% \optrule
%%%
%%% the options to timeline are:
%%%      length The amount of vertical space that the timeline should
%%%                use.
%%%      (start,stop) indicate the range of the timeline. All dates or
%%%                sortkeys should lie in the range [start,stop]
%%%
%%% \item without the sort key expects date to be a number (such as a
%%%      year).
%%% \item with the sort key expects the sort key to be a number; date
%%%      can be anything. This can be used for log scale time lines
%%%      or dates that include months or days.
%%% putting \optrule inside of the timeline environment will cause a
%%%      vertical rule to be drawn down the center of the timeline.

I've used python's datetime.data.toordinal to convert dates to 'sort keys' in the context of the package.

I have finally found a working code - try this:

document.getElementById("button").style.background='#000000';

For python 3.8.6/3.9, I had to do some dirty hacks, because perfplot was giving out some errors. Here assume that x[0] is a a and x[1] is b:

The plot is nearly same for large data. For small data,

Taken by perfplot and this is the code, large data == range(8), small data == range(4).

import perfplot

from random import choice
from string import ascii_lowercase as letters

def generate_random(x):
    data = ''.join(choice(letters) for i in range(x))
    sata = ''.join(choice(letters) for i in range(x))
    return [data,sata]

def fstring_func(x):
    return [ord(i) for i in f'{x[0]}{x[1]}']

def format_func(x):
    return [ord(i) for i in "{}{}".format(x[0], x[1])]

def replace_func(x):
    return [ord(i) for i in "|~".replace('|', x[0]).replace('~', x[1])]

def join_func(x):
    return [ord(i) for i in "".join([x[0], x[1]])]

perfplot.show(
    setup=lambda n: generate_random(n),
    kernels=[
        fstring_func,
        format_func,
        replace_func,
        join_func,
    ],
    n_range=[int(k ** 2.5) for k in range(4)],
)

When medium data is there, and 4 strings are there x[0], x[1], x[2], x[3] instead of 2 string:

def generate_random(x):
    a =  ''.join(choice(letters) for i in range(x))
    b =  ''.join(choice(letters) for i in range(x))
    c =  ''.join(choice(letters) for i in range(x))
    d =  ''.join(choice(letters) for i in range(x))
    return [a,b,c,d]

Better to stick with fstrings

You have two ways to do that:

METHOD 1. The secure way.

Put the images on /www/htdocs/

<?php
    $www_root = 'http://localhost/images';
    $dir = '/var/www/images';
    $file_display = array('jpg', 'jpeg', 'png', 'gif');

    if ( file_exists( $dir ) == false ) {
       echo 'Directory \'', $dir, '\' not found!';
    } else {
       $dir_contents = scandir( $dir );

        foreach ( $dir_contents as $file ) {
           $file_type = strtolower( end( explode('.', $file ) ) );
           if ( ($file !== '.') && ($file !== '..') && (in_array( $file_type, $file_display)) ) {
              echo '<img src="', $www_root, '/', $file, '" alt="', $file, '"/>';
           break;
           }
        }
    }
?>

METHOD 2. Unsecure but more flexible.

Put the images on any directory (apache must have permission to read the file).

<?php
    $dir = '/home/user/Pictures';
    $file_display = array('jpg', 'jpeg', 'png', 'gif');

    if ( file_exists( $dir ) == false ) {
       echo 'Directory \'', $dir, '\' not found!';
    } else {
       $dir_contents = scandir( $dir );

        foreach ( $dir_contents as $file ) {
           $file_type = strtolower( end( explode('.', $file ) ) );
           if ( ($file !== '.') && ($file !== '..') && (in_array( $file_type, $file_display)) ) {
              echo '<img src="file_viewer.php?file=', base64_encode($dir . '/' . $file), '" alt="', $file, '"/>';
           break;
           }
        }
    }
?>

And create another script to read the image file.

<?php
    $filename = base64_decode($_GET['file']);
    // Check the folder location to avoid exploit
    if (dirname($filename) == '/home/user/Pictures')
        echo file_get_contents($filename);
?>

$(document).ready(function() {_x000D_
  $("a").click(function(event) {_x000D_
    var myClass = $(this).attr("class");_x000D_
    var myId = $(this).attr('id');_x000D_
    alert(myClass + " " + myId);_x000D_
  });_x000D_
})

<html>_x000D_
_x000D_
<head>_x000D_
  <script type="text/javascript" src="http://code.jquery.com/jquery-1.7.2.min.js"></script>_x000D_
</head>_x000D_
_x000D_
<body>_x000D_
  <a href="#" id="kana1" class="konbo">click me 1</a>_x000D_
  <a href="#" id="kana2" class="kinta">click me 2</a>_x000D_
</body>_x000D_
_x000D_
</html>

This works for me. There is no event.target.class function in jQuery.

Because the original question relates to an array of numbers and I am using an array of strings I couldn't make the given examples work.

I found that each string needed to be encapsulated in single quotes to work with the IN() function.

Here is my solution

foreach($status as $status_a) {
        $status_sql[] = '\''.$status_a.'\'';
    }
    $status = implode(',',$status_sql);

$sql = mysql_query("SELECT * FROM table WHERE id IN ($status)");

As you can see the first function wraps each array variable in single quotes (\') and then implodes the array.

NOTE: $status does not have single quotes in the SQL statement.

There is probably a nicer way to add the quotes but this works.

For windows users, there is an easy fix. Download whl files from:

https://www.lfd.uci.edu/~gohlke/pythonlibs/#pyqt4

run from anaconda prompt pip install PyQt4-4.11.4-cp37-cp37m-win_amd64.whl

i Solve My Problem Through this Method

Easiest way for checking file is empty or not:

if [ -s /path-to-file/filename.txt ]
then
     echo "File is not empty"
else
     echo "File is empty"
fi

You can also write it on single line:

[ -s /path-to-file/filename.txt ] && echo "File is not empty" || echo "File is empty"

To expand on another answer, here is a fairly complete example which can cleanup the tmpdir even on exceptions:

import contextlib
import os
import shutil
import tempfile

@contextlib.contextmanager
def cd(newdir, cleanup=lambda: True):
    prevdir = os.getcwd()
    os.chdir(os.path.expanduser(newdir))
    try:
        yield
    finally:
        os.chdir(prevdir)
        cleanup()

@contextlib.contextmanager
def tempdir():
    dirpath = tempfile.mkdtemp()
    def cleanup():
        shutil.rmtree(dirpath)
    with cd(dirpath, cleanup):
        yield dirpath

def main():
    with tempdir() as dirpath:
        pass # do something here

You can use setCustomValidity function when oninvalid event occurs.

Like below:-

<input class="form-control" type="email" required="" 
    placeholder="username" oninvalid="this.setCustomValidity('Please Enter valid email')">
</input>

Update:-

To clear the message once you start entering use oninput="setCustomValidity('') attribute to clear the message.

<input class="form-control" type="email"  required="" placeholder="username"
 oninvalid="this.setCustomValidity('Please Enter valid email')"
 oninput="setCustomValidity('')"></input>

Using test

if test ! -z "$(docker images -q <name:tag>)"; then
  echo "Exist"
fi

or in one line

test ! -z "$(docker images -q <name:tag>)" &&  echo exist

As stated multiple times, inversion is achieved by the -v option to grep. Let me add the (hopefully amusing) note that you could have figured this out yourself by grepping through the grep help text:

grep --help | grep invert

-v, --invert-match select non-matching lines

Docker - alternative approach

Docker is some-kind of super-fast virtual machine which can be use to run tools like node (instead install them directly on mac-os). Advantages to do it are following

• all stuff ('milions' node files) are install inside docker image/container (they encapsulated in few inner-docker files)

• you can map your mac directory with project to your docker container and have access to node - but outside docker, mac-os sytem don't even know that node is installed. So you get some kind of 'virtual' console with available node commands which can works on real files

• you can easily kill node by find it by docker ps and kill by docker rm -f name_or_num

• you can easily uninstall docker image/containers by one command docker rmi ... and get free space - and install it again by run script (below)

• your node is encapsulated inside docker and don't have access to whole system - only to folders you map to it

• you can run node services and easily map they port to mac port and have access to it from web browser

• you can run many node versions at the same time

• in similar way you can install other tools like (in many versions in same time): php, databases, redis etc. - inside docker without any interaction with mac-os (which not notice such software at all). E.g. you can run at the same time 3 mysql db with different versions and 3 php application with different php version ... - so you can have many tools but clean system

• TEAM WORK: such enviroment can be easily cloned into other machines (and even to windows/linux systems - with some modifications) and provide identical docker-level environment - so you can easily set up and reuse you scripts/dockerfiles, and setup environment for new team member in very fast way (he just need to install docker and create similar folder-structure and get copy of scripts - thats all). I work this way for 2 year and with my team - and we are very happy

Instruction

• Install docker using e.g. this instructions

• Prepare 'special' directory for work e.g. my directory is /Users/kamil/work (I will use this directory further - but it can be arbitrary) - this directory will be 'interface' between docker containers and your mac file ststem. Inside this dir create following dir structure:

  /Users/kamil/work/code - here you put your projects with code

  /Users/kamil/work/tools

  /Users/kamil/work/tools/docker-data - here we map containers output data like logs (or database files if someone ouse db etc.)

  /Users/kamil/work/tools/docker

  /Users/kamil/work/tools/docker/node-cmd - here we put docker node scripts

• inside tools create file .env which will contain in one place global-paths used in other scripts

  _x000D_

  _x000D_

  toolspath="/Users/kamil/work/tools"
  codepath="/Users/kamil/work/code"
  workpath=/Users/kamil/work

  _x000D_

  _x000D_
  _x000D_

• innside dir ../node-cmd create file dockerfile with following content

  _x000D_

  _x000D_

  # default  /var/www/html (mapped to .../code folder with projects)
  FROM node
  
  WORKDIR /work
  
  # Additional arbitrary tools (ng, gulp, bower)
  RUN npm install -g n @angular/cli bower gulp grunt
  
  CMD while true; do sleep 10000; done
  
  # below ports are arbitrary
  EXPOSE 3002 3003 3004 4200

  _x000D_

  _x000D_
  _x000D_

• innside dir ../node-cmd create file run-container with following content (this file should be executable e.g. by chmod +x run-container) - (notice how we map port-s and directories form external 'world' to internal docker filesystem)

  _x000D_

  _x000D_

  set -e
  cd -- "$(dirname "$0")" # this script dir (not set on doubleclick)
  source ../../.env
  toolsdir=$toolspath/docker-data
  workdir=$workpath
  
  if [ ! "$(docker ps | grep node-cmd)" ] 
  then 
    docker build -t node-cmd .
    docker rm -f node-cmd |:
    docker run -d --name node-cmd -p 4200:4200 -p 4201:4201 -p 3002:3002 -p 3003:3003 -p 3004:3004 -v $toolsdir/node-cmd/logs:/root/.npm/_logs -v $workdir:/work node-cmd
  fi

  _x000D_

  _x000D_
  _x000D_

• ok now you can add some project e.g. work/code/myProject and add to it following file 'run-cmd' (must be executable)

  _x000D_

  _x000D_

  cd -- "$(dirname "$0")"
  ../../tools/docker/node-cmd/run-container
  docker exec -it node-cmd bash -c "cd /work/code/myProject; bash"

  _x000D_

  _x000D_
  _x000D_

• then if you run above script (by double-click), you will see console with available node commands in project directory e.g. npm install

• to run project in background (e.g some serwice) e.g. run web-server angular-cli application you can use following script (named run-front -must be executable) - (you must also edit /etc/hosts file to add proper domain)

  _x000D_

  _x000D_

  cd -- "$(dirname "$0")"
  open "http://my-angular.local:3002"
  ../../tools/docker/node-cmd/run-container
  docker exec -it node-cmd  /bin/sh -c "cd /work/code/my-angular-project; npm start"
  cat         # for block script and wait for user ctrl+C

The appropriate LC would be

[entry for tag in tags for entry in entries if tag in entry]

The order of the loops in the LC is similar to the ones in nested loops, the if statements go to the end and the conditional expressions go in the beginning, something like

[a if a else b for a in sequence]

See the Demo -

>>> tags = [u'man', u'you', u'are', u'awesome']
>>> entries = [[u'man', u'thats'],[ u'right',u'awesome']]
>>> [entry for tag in tags for entry in entries if tag in entry]
[[u'man', u'thats'], [u'right', u'awesome']]
>>> result = []
    for tag in tags:
        for entry in entries:
            if tag in entry:
                result.append(entry)


>>> result
[[u'man', u'thats'], [u'right', u'awesome']]

EDIT - Since, you need the result to be flattened, you could use a similar list comprehension and then flatten the results.

>>> result = [entry for tag in tags for entry in entries if tag in entry]
>>> from itertools import chain
>>> list(chain.from_iterable(result))
[u'man', u'thats', u'right', u'awesome']

Adding this together, you could just do

>>> list(chain.from_iterable(entry for tag in tags for entry in entries if tag in entry))
[u'man', u'thats', u'right', u'awesome']

You use a generator expression here instead of a list comprehension. (Perfectly matches the 79 character limit too (without the list call))

Edited: Kindly note that
whereBetween('date',$start_date,$end_date)
is inclusive of the first date.

After upgrading from Ubuntu 14.04 lts to Ubuntu 16.04 lts I found a yet another reason for this error that I haven't seen before.

During the upgrading process I had somehow lost my php5-fpm executable altogether. All the config files were intact and it took me a while to realize that service php5-fpm start didn't really start a process, as it did not show any errors.

My moment of awakening was when I noticed that there were no socket file in /var/run/php5-fpm.sock, as there should be, nor did netstat -an show processes listening on the port that I tried as an alternative while trying to solve this problem. Since the file /usr/sbin/php5-fpm was also non-existing, I was finally on the right track.

In order to solve this problem I upgraded php from version 5.5 to 7.0. apt-get install php-fpm did the trick as a side effect. After that and installing other necessary packages everything was back to normal.

This upgrading solution may have problems of its own, however. Since php has evolved quite a bit, it's possible that the software will break in unimaginable ways. So, even though I did go down that path, you may want to keep the version you're fond of just for a while longer.

Luckily, there seems to be a neat way for that, as described on The Customize Windows site:

add-apt-repository ppa:ondrej/php
apt-get purge php5-common
apt-get update
apt-get install php5.6

Neater solution as it might be, I didn't try that. I expect the next couple of days will tell me whether I should have.

Even better when choosing the Assembly location. Filter most of the assemblies if you know all your implemented interfaces are within the same Assembly.DefinedTypes.

// We get the assembly through the base class
var baseAssembly = typeof(baseClass).GetTypeInfo().Assembly;

// we filter the defined classes according to the interfaces they implement
var typeList = baseAssembly.DefinedTypes.Where(type => type.ImplementedInterfaces.Any(inter => inter == typeof(IMyInterface))).ToList();

I think restful authentication involves the passing of an authentication token as a parameter in the request. Examples are the use of apikeys by api's. I don't believe the use of cookies or http auth qualifies.

When peer close, you just do not know whether it just stop sending or both sending and receiving.Because TCP allows this, btw, you should know the difference between close and shutdown. If peer both stop sending and receiving, first you send some bytes, it will succeed. But the peer kernel will send you RST. So subsequently you send some bytes, your kernel will send you SIGPIPE signal, if you catch or ignore this signal, when your send returns, you just get Broken pipe error, or if you don't , the default behavior of your program is crashing.

The solution given by luschn and pillravi works fine unless you receive a Strict-Transport-Security header in the response.

Adding withCredentials: true will solve that issue.

  axios.post(session_url, {
    withCredentials: true,
    headers: {
      "Accept": "application/json",
      "Content-Type": "application/json"
    }
  },{
    auth: {
      username: "USERNAME",
      password: "PASSWORD"
  }}).then(function(response) {
    console.log('Authenticated');
  }).catch(function(error) {
    console.log('Error on Authentication');
  });

You can use this Q2C.SSMSPlugin, which is free and open source. You can right click and select "Execute Query To Command... -> Query To Insert...". Enjoy)

Further to @RobG's pure / vanilla javascript answer, you can reset to the 'default' value with

selectElement.selectedIndex = null;

It seems -1 deselects all items, null selects the default item, and 0 or a positive number selects the corresponding index option.

Options in a select object are indexed in the order in which they are defined, starting with an index of 0.

I faced the same problem and solve it by this method. html :

<div id="parentDiv">
   <div id="childDiv">
     AAA
   </div>
    BBBB
</div>

JS:

$(document).ready(function(){
 $("#parentDiv").click(function(e){
   if(e.target.id=="childDiv"){
     childEvent();
   } else {
     parentEvent();
   }
 });
});

function childEvent(){
    alert("child event");
}

function parentEvent(){
    alert("paren event");
}

Short answer: classmaps are static while PSR autoloading is dynamic.

If you don't want to use classmaps, use PSR autoloading instead.

Using both eval and creating a new Function to execute javascript comes with a lot of security risks.

const script = document.createElement("script");
const stringJquery = '$("#button").on("click", function() {console.log("hit")})';
script.text = stringJquery;
document.body.appendChild(script);

I prefer this method to execute the Javascript I receive as a string.

here's what six is:

pip search six
six                       - Python 2 and 3 compatibility utilities

to install:

pip install six

though if you did install python-dateutil from pip six should have been set as a dependency.

N.B.: to install pip run easy_install pip from command line.

You can of course change the order of the columns in a sql statement. However if you want to abstract tables' physical column order, you can create a view. i.e

CREATE TABLE myTable(
    a int NULL,
    b varchar(50) NULL,
    c datetime NULL
);


CREATE VIEW vw_myTable
AS
SELECT c, a, b
  FROM myTable;

select * from myTable;
a  b  c
-  -  -

select * from vw_myTable
c  a  b
-  -  -

If you want to create model along with migration use this command:-

sequelize model:create --name regions --attributes name:string,status:boolean --underscored

--underscored it is used to create column having underscore like:- created_at,updated_at or any other column having underscore and support user defined columns having underscore.

I think this is the simple form

Button1.layer.cornerRadius = 10(Half of the length and width)
Button1.layer.borderWidth = 2

You forgot the # on the id selector:

if ($("#EventStartTimeMin").val() === "") {
    // ...
}

brew install mysql added mysql to /usr/local/Cellar/..., so I needed to add :/usr/local/Cellar/ to my $PATH and then which mysql_config worked!

With Sharepoint Designer you can edit the CAML of your XSLT List View.

If you set the Scope attribute of the View element to Recursive or RecursiveAll, which returns all Files and Folders, you can filter the documents by FileDirRef:

<Where>
   <Contains>
      <FieldRef Name='FileDirRef' />
      <Value Type='Lookup'>MyFolder</Value>
   </Contains>
</Where>

This returns all documents which contain the string 'MyFolder' in their path.

This question seems to be the most popular one for disabling textarea wrap. However, as of April 2017 I find that IE 11 (11.0.9600) will not disable word wrap with any of the above solutions.

The only solution which does work for IE 11 is wrap="off". wrap="soft" and/or the various CSS attributes like white-space: pre alter where IE 11 chooses to wrap but it still wraps somewhere. Note that I have tested this with or without Compatibility View. IE 11 is pretty HTML 5 compatible, but not in this case.

Thus, to achieve lines which retain their whitespace and go off the right-hand side I am using:

<textarea style="white-space: pre; overflow: scroll;" wrap="off">

Fortuitously this does seem to work in Chrome & Firefox too. I am not defending the use of pre-HTML 5 wrap="off", just saying that it seems to be required for IE 11.

There are a number of different options, based on what exactly the effect you're going for is. Chris Coyier did a piece on just this way back when. Worth a read:

http://css-tricks.com/perfect-full-page-background-image/

I don't know if this what you want but try to remove overflow: hidden from #wrap

I got the same problem when accessing mysql with root. The problem I found is that some database files does not have permission by the mysql user, which is the user that started the mysql server daemon.

We can check this with ls -l /var/lib/mysql command, if the mysql user does not have permission of reading or writing on some files or directories, that might cause problem. We can change the owner or mode of those files or directories with chown/chmod commands.

After these changes, restart the mysqld daemon and login with root with command:

mysql -u root

Then change passwords or create other users for logging into mysql.

append([]int{1,2}, []int{3,4}...) will work. Passing arguments to ... parameters.

If f is variadic with a final parameter p of type ...T, then within f the type of p is equivalent to type []T.

If f is invoked with no actual arguments for p, the value passed to p is nil.

Otherwise, the value passed is a new slice of type []T with a new underlying array whose successive elements are the actual arguments, which all must be assignable to T. The length and capacity of the slice is therefore the number of arguments bound to p and may differ for each call site.

Given the function and calls

func Greeting(prefix string, who ...string)
Greeting("nobody")
Greeting("hello:", "Joe", "Anna", "Eileen")

You will need to add the jar to your local maven repository. Alternatively (better option) specify the proper repository (if one exists) so it can be automatically downloaded by maven

In either case, remove the <systemPath> tag from the dependency

I'm new to node.js (about 2 weeks), but I've just created a module that recursively reports to the console the contents of an object. It will list all or search for a specific item and then drill down by a given depth if need be.

Perhaps you can customize this to fit your needs. Keep It Simple! Why complicate?...

'use strict';

//console.log("START: AFutils");

// Recusive console output report of an Object
// Use this as AFutils.reportObject(req, "", 1, 3); // To list all items in req object by 3 levels
// Use this as AFutils.reportObject(req, "headers", 1, 10); // To find "headers" item and then list by 10 levels
// yes, I'm OLD School!  I like to see the scope start AND end!!!  :-P
exports.reportObject = function(obj, key, level, deep) 
{
    if (!obj)
    { 
        return;
    }

    var nextLevel = level + 1;

    var keys, typer, prop;
    if(key != "")
    {   // requested field
        keys = key.split(']').join('').split('[');
    }
    else
    {   // do for all
        keys = Object.keys(obj);
    }
    var len = keys.length;
    var add = "";
    for(var j = 1; j < level; j++)
    {
        // I would normally do {add = add.substr(0, level)} of a precreated multi-tab [add] string here, but Sublime keeps replacing with spaces, even with the ["translate_tabs_to_spaces": false] setting!!! (angry)
        add += "\t";
    }

    for (var i = 0; i < len; i++) 
    {
        prop = obj[keys[i]];
        if(!prop)
        {
            // Don't show / waste of space in console window...
            //console.log(add + level + ": UNDEFINED [" + keys[i] + "]");
        }
        else
        {
            typer = typeof(prop);
            if(typer == "function")
            {
                // Don't bother showing fundtion code...
                console.log(add + level + ": [" + keys[i] + "] = {" + typer + "}");
            }
            else
            if(typer == "object")
            {
                console.log(add + level + ": [" + keys[i] + "] = {" + typer + "}");
                if(nextLevel <= deep)
                {
                    // drop the key search mechanism if first level item has been found...
                    this.reportObject(prop, "", nextLevel, deep); // Recurse into
                }
            }
            else
            {
                // Basic report
                console.log(add + level + ": [" + keys[i] + "] = {" + typer + "} = " + prop + ".");
            }
        }
    }
    return ;
};

//console.log("END: AFutils");

A couple of things to note:

1. Non-JavaScript enabled clients won't be able to submit your form
2. The w3c specification does not allow nested forms in HTML - you'll potentially find that the action and method tags are ignored for this form in modern browsers, and that other ASP.NET controls no longer post-back correctly (as their form has been closed).

If you want it to be treated as a proper ASP.NET postback, you can call the methods supplied by the framework, namely __doPostBack(eventTarget, eventArgument):

<div name="mysubmitbutton" id="mysubmitbutton" class="customButton"
     onclick="javascript:__doPostBack('<%=mysubmitbutton.ClientID %>', 'MyCustomArgument');">
  Button Text
</div>

You can make an AMI of an existing instance, and then launch other instances using that AMI.

Here's a concrete example:

Suppose you have a function that calculates the gravitational force acting on an object. If you don't know the formula, you can find it here. This function takes in the three necessary parameters as arguments.

Now, being on the earth, you only want to calculate forces for objects on this planet. In a functional language, you could pass in the mass of the earth to the function and then partially evaluate it. What you'd get back is another function that takes only two arguments and calculates the gravitational force of objects on earth. This is called currying.

if the project is not a big ,

1- change the name of folder project

2- make a new project with the same project (before renaming)

3- add existing files from the old project to the new project (totally same , same folders , same names , ...)

4- open the the new project file (as xml ) and the old project

5- copy the new project file (xml content ) and paste it in the old project file

6- delete the old project

7- rename the old folder project to old name

your question doesn't sound as if you even tried it yourself, so i shouldn't even think of answering, but: if a hidden div can't be printed with that one line:

$('SelectorToPrint').printElement();

simply change it to:

$('SelectorToPrint').show().printElement();

which should make it work in all cases.

for the rest, there's no solution. the plugin will open the print-dialog for you where the user has to choose his printer. you simply can't find out if a printer is attached with javascript (and you (almost) can't print without print-dialog - if you're thinking about that).

NOTE:

The $.browser object has been removed in version 1.9.x of jQuery making this library unsupported.

No, these defines are compiler dependent. What you can do, use your own set of defines, and set them on the Makefile. See this thread for more info.

Please see https://github.com/joshua-gould/canvas2pdf. This library creates a PDF representation of your canvas element, unlike the other proposed solutions which embed an image in a PDF document.

//Create a new PDF canvas context.
var ctx = new canvas2pdf.Context(blobStream());

//draw your canvas like you would normally
ctx.fillStyle='yellow';
ctx.fillRect(100,100,100,100);
// more canvas drawing, etc...

//convert your PDF to a Blob and save to file
ctx.stream.on('finish', function () {
    var blob = ctx.stream.toBlob('application/pdf');
    saveAs(blob, 'example.pdf', true);
});
ctx.end();

I was having same issue. After some digging I realized that many post/pre-install scripts would try to install various dependencies and some times specific repositories are used. A better way is to disable certificate check for https module for nodejs that worked for me.

process.env.NODE_TLS_REJECT_UNAUTHORIZED = "0"

From this question

A few considerations on the subject:

• The parenthesis:

  The browser (engine/parser) associates the keyword function with

  [optional name]([optional parameters]){...code...}
  

  So in an expression like function(){}() the last parenthesis makes no sense.

  Now think at

  name=function(){} ; name() !?
  

Yes, the first pair of parenthesis force the anonymous function to turn into a variable (stored expression) and the second launches evaluation/execution, so ( function(){} )() makes sense.

• The utility: ?

  1. For executing some code on load and isolate the used variables from the rest of the page especially when name conflicts are possible;

  2. Replace eval("string") with

     (new Function("string"))()

  3. Wrap long code for " =?: " operator like:

     result = exp_to_test ? (function(){... long_code ...})() : (function(){...})();

Ensure that mobile devices won't change the font with their default font by using important along with the universal selector * :

* { font-family: Algerian !important;}

You are correct in guessing that the aim of using string builder is not achieved, at least not to its full extent.

However, when the compiler sees the expression "select id1, " + " id2 " + " from " + " table" it emits code which actually creates a StringBuilder behind the scenes and appends to it, so the end result is not that bad afterall.

But of course anyone looking at that code is bound to think that it is kind of retarded.

I've found a more reliable method (at least on Excel 2016 for Mac) is:

Assuming your long list is in column A, and the list of things to be removed from this is in column B, then paste this into all the rows of column C:

= IF(COUNTIF($B$2:$B$99999,A2)>0,"Delete","Keep")

Then just sort the list by column C to find what you have to delete.

In this specific case (there is always a single character at the start you want to remove) you'll want:

str.substring(1)

However, if you want to be able to detect if the comma is there and remove it if it is, then something like:

if (str[0] == ',') { 
  str = str.substring(1);
}

In Laravel 6 there is a channel called 'stderr'. See config/logging.php:

'stderr' => [
    'driver' => 'monolog',
    'handler' => StreamHandler::class,
    'formatter' => env('LOG_STDERR_FORMATTER'),
    'with' => [
        'stream' => 'php://stderr',
    ],
],

In your controller:

use Illuminate\Support\Facades\Log;

Log::channel('stderr')->info('Something happened!');

The | operator in a regular expression means or. That is to say either string1 or string2 will match. You could do:

grep 'string1' filename | grep 'string2'

which will pipe the results from the first command into the second grep. That should give you only lines that match both.

The formula in C1

=IF(A1=1,B1,"")

is either giving an answer of "" (which isn't treated as blank) or the contents of B1.

If you want the formula in D1 to show TRUE if C1 is "" and FALSE if C1 has something else in then use the formula

=IF(C2="",TRUE,FALSE)

instead of ISBLANK

The Light,

You can configure the process acting as the client to use fiddler as a proxy.

Fiddler sets itself up as a proxy conveniently on 127.0.0.1:8888, and by default overrides the system settings under Internet Options in the Control Panel (if you've configured any) such that all traffic from the common protocols (http, https, and ftp) goes to 127.0.0.1:8888 before leaving your machine.

Now these protocols are often from common processes such as browsers, and so are easily picked up by fiddler. However, in your case, the process initiating the requests is probably not a browser, but one for a programming language like php.exe, or java.exe, or whatever language you are using.

If, say, you're using php, you can leverage curl. Ensure that the curl module is enabled, and then right before your code that invokes the request, include:

curl_setopt($ch, CURLOPT_PROXY, '127.0.0.1:8888');

Hope this helps. You can also always lookup stuff like so from the fiddler documentation for a basis for you to build upon e.g. http://docs.telerik.com/fiddler/Configure-Fiddler/Tasks/ConfigurePHPcURL

you have to create an entry inside res/menu,override onCreateOptionsMenu and inflate it

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.yourentry, menu);
    return true;
}

an entry for the menu could be:

<menu xmlns:android="http://schemas.android.com/apk/res/android" >
    <item
        android:id="@+id/action_cart"
        android:icon="@drawable/cart"
        android:orderInCategory="100"
        android:showAsAction="always"/> 
</menu>
