Here's a more visual explanation in the context of a MVVM architecture:

Updated after Alfe pointed out you don't need to check for float separately as complex handles both:

def is_number(s):
    try:
        complex(s) # for int, long, float and complex
    except ValueError:
        return False

    return True

Previously said: Is some rare cases you might also need to check for complex numbers (e.g. 1+2i), which can not be represented by a float:

def is_number(s):
    try:
        float(s) # for int, long and float
    except ValueError:
        try:
            complex(s) # for complex
        except ValueError:
            return False

    return True

This one, from kristopherjohnson is heaps better:

1. It doesn't require an XML document header either.
2. Has clearer exceptions
3. Adds extra behaviour options: OmitXmlDeclaration = true, NewLineOnAttributes = true

4. Less lines of code

   static string PrettyXml(string xml)
   {
       var stringBuilder = new StringBuilder();
   
       var element = XElement.Parse(xml);
   
       var settings = new XmlWriterSettings();
       settings.OmitXmlDeclaration = true;
       settings.Indent = true;
       settings.NewLineOnAttributes = true;
   
       using (var xmlWriter = XmlWriter.Create(stringBuilder, settings))
       {
           element.Save(xmlWriter);
       }
   
       return stringBuilder.ToString();
   }
   

1. Go to working directory where you project folder (cloned folder) is placed.
2. Now delete the folder.
3. in windows just right click and do delete.
4. in command line use rm -r "folder name"
5. this worked for me

take look at my solution

I have this HTML table Head

<thead>
    <tr>
        <th style="width: 20%">@L("Id")</th>
        <th style="width: 20%">@L("IdentityNumber")</th>
        <th style="width: 20%">@L("Name")</th>
        <th style="width: 20%">@L("MobileNumber")</th>
        <th style="width: 20%">@L("RegistrationStatus")</th>
        <th style="width: 20%">@L("RegistrationStatusId")</th>
        <th style="width: 20%; text-align: center;" data-hide="phone">@L("Actions")</th>
    </tr>
</thead>

and my Ajax request returned something like this

so I want to hide Id index [0] and RegistrationStatusId index [5]

$(document).ready(function() {
    $('#example').dataTable( {
        "columnDefs": [
            { "aTargets": [0, 5], "sClass": "invisible"},// here is the tricky part
        ]
    });
});

I hope this would help you

Use regular expression:

String s="your1string2contain3with4number";
int i=Integer.parseInt(s.replaceAll("[\\D]", ""));

output: i=1234;

If you need first number combination then you should try below code:

String s="abc123xyz456";
int i=NumberFormat.getInstance().parse(s).intValue();

output: i=123;

Consider using JSONPath https://packagist.org/packages/flow/jsonpath

There is a pretty clear explanation of how to use it and parse a JSON-file avoiding all the loops proposed. If you are familiar with XPath for XML you will start loving this approach.

Try this:

a = 1
b = 2
int_div  = a // b

Yes, Its possible in SQL, but we can't set more than one primary keys in MsAccess. Then, I don't know about the other databases.

CREATE TABLE CHAPTER (
    BOOK_ISBN VARCHAR(50) NOT NULL,
    IDX INT NOT NULL,
    TITLE VARCHAR(100) NOT NULL,
    NUM_OF_PAGES INT,
    PRIMARY KEY (BOOK_ISBN, IDX)
);

Read about Storage Engines.

MyISAM:

The MyISAM storage engine in MySQL.

• Simpler to design and create, thus better for beginners. No worries about the foreign relationships between tables.
• Faster than InnoDB on the whole as a result of the simpler structure thus much less costs of server resources. -- Mostly no longer true.
• Full-text indexing. -- InnoDB has it now
• Especially good for read-intensive (select) tables. -- Mostly no longer true.
• Disk footprint is 2x-3x less than InnoDB's. -- As of Version 5.7, this is perhaps the only real advantage of MyISAM.

InnoDB:

The InnoDB storage engine in MySQL.

• Support for transactions (giving you support for the ACID property).
• Row-level locking. Having a more fine grained locking-mechanism gives you higher concurrency compared to, for instance, MyISAM.
• Foreign key constraints. Allowing you to let the database ensure the integrity of the state of the database, and the relationships between tables.
• InnoDB is more resistant to table corruption than MyISAM.
• Support for large buffer pool for both data and indexes. MyISAM key buffer is only for indexes.
• MyISAM is stagnant; all future enhancements will be in InnoDB. This was made abundantly clear with the roll out of Version 8.0.

MyISAM Limitations:

• No foreign keys and cascading deletes/updates
• No transactional integrity (ACID compliance)
• No rollback abilities
• 4,284,867,296 row limit (2^32) -- This is old default. The configurable limit (for many versions) has been 2**56 bytes.
• Maximum of 64 indexes per table

InnoDB Limitations:

• No full text indexing (Below-5.6 mysql version)
• Cannot be compressed for fast, read-only (5.5.14 introduced ROW_FORMAT=COMPRESSED)
• You cannot repair an InnoDB table

I needed something a bit different than what these solutions gave, in that I needed to create an array with a number of distinct random numbers held to a specified range. Below is my solution.

function getDistinctRandomIntForArray(array, range){
   var n = Math.floor((Math.random() * range));
   if(array.indexOf(n) == -1){        
    return n; 
   } else {
    return getDistinctRandomIntForArray(array, range); 
   }
}

function generateArrayOfRandomInts(count, range) {
   var array = []; 
   for (i=0; i<count; ++i){
    array[i] = getDistinctRandomIntForArray(array, range);
   };
   return array; 
}

I would have preferred to not create a loop that has the possibility to end up with a lot of unnecessary calls (if your count, and range are high and are close to the same number) but this is the best I could come up with.

To solve this simply add android:windowSoftInputMode="stateVisible|adjustPan to that activity in android manifest file. for example

<activity 
    android:name="com.comapny.applicationname.activityname"
    android:screenOrientation="portrait"
    android:windowSoftInputMode="stateVisible|adjustPan"/>

Add an id then to each

<li> add data-target="myMenu" data-toggle="collapse"
<div id="myMenu" class="nav-collapse">
    <ul class="nav">
      <li class="active" data-target="myMenu" data-toggle="collapse"><a href="#home">Home</a></li>
      <li data-target="myMenu" data-toggle="collapse"><a href="#about">About</a></li>
      <li data-target="myMenu" data-toggle="collapse"><a href="#portfolio">Portfolio</a></li>
      <li data-target="myMenu" data-toggle="collapse"><a href="#services">Services</a></li>
      <li data-target="myMenu" data-toggle="collapse"><a href="#contact">Contact</a></li>
    </ul>
</div>

You can access it by the class' private attributes:

cls_name = self.__class__.__name__

EDIT:

As said by Ned Batcheler, this wouldn't work in the class body, but it would in a method.

Try to install your application by using yum command yum install application_name

Here is my summary of this problem: 5 Ways of Calling Java from Python

http://baojie.org/blog/2014/06/16/call-java-from-python/ (cached)

Short answer: Jpype works pretty well and is proven in many projects (such as python-boilerpipe), but Pyjnius is faster and simpler than JPype

I have tried Pyjnius/Jnius, JCC, javabridge, Jpype and Py4j.

Py4j is a bit hard to use, as you need to start a gateway, adding another layer of fragility.

This prevent from the multiple inclusion of same header file multiple time.

#ifndef __COMMON_H__
#define __COMMON_H__
//header file content
#endif

Suppose you have included this header file in multiple files. So first time __COMMON_H__ is not defined, it will get defined and header file included.

Next time __COMMON_H__ is defined, so it will not include again.

For Swift 3, many Foundation types have dropped the 'NS' prefix, so you'd access it by UUID().uuidString.

As mentioned in the comments to the question, the JDBC-ODBC Bridge is - as the name indicates - only a mechanism for the JDBC layer to "talk to" the ODBC layer. Even if you had a JDBC-ODBC Bridge on your Mac you would also need to have

• an implementation of ODBC itself, and
• an appropriate ODBC driver for the target database (ACE/Jet, a.k.a. "Access")

So, for most people, using JDBC-ODBC Bridge technology to manipulate ACE/Jet ("Access") databases is really a practical option only under Windows. It is also important to note that the JDBC-ODBC Bridge will be has been removed in Java 8 (ref: here).

There are other ways of manipulating ACE/Jet databases from Java, such as UCanAccess and Jackcess. Both of these are pure Java implementations so they work on non-Windows platforms. For details on how to use UCanAccess see

Manipulating an Access database from Java without ODBC

My problem was unrelated to processData. It was because I sent a function that cannot be called later with apply because it did not have enough arguments. Specifically I shouldn't have used alert as the error callback.

$.ajax({
    url: csvApi,
    success: parseCsvs,
    dataType: "json",
    timeout: 5000,
    processData: false,
    error: alert
});

See this answer for more information on why that can be a problem: Why are certain function calls termed "illegal invocations" in JavaScript?

The way I was able to discover this was by adding a console.log(list[ firingIndex ]) to jQuery so I could track what it was firing.

This was the fix:

function myError(jqx, textStatus, errStr) {
    alert(errStr);
}

$.ajax({
    url: csvApi,
    success: parseCsvs,
    dataType: "json",
    timeout: 5000,
    error: myError // Note that passing `alert` instead can cause a "jquery.js:3189 Uncaught TypeError: Illegal invocation" sometimes
});

You can just follow instructions from the Homebrew on Linux docs, but I think it is better to understand what the instructions are trying to achieve.

Understanding the installation steps can save some time

Step 1: Choose location

First of all, it is important to understand that linuxbrew will be installed on the /home directory and not inside /home/your-user (the ~ directory).
(See the reason for that at the end of answer).
Keep this in mind when you run the other steps below.

Step 2: Add linuxbrew binaries to /home :

The installation script will do it for us:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

Step 3: Check that /linuxbrew was added to the relevant location

This can be done by simply navigating to /home.
Notice that the docs are showing it as a one-liner by adding test -d <linuxbrew location> before each command.

(Read more about the test command in here).

Step 4: Export relevant environment variables to terminal

We need to add linuxbrew to PATH and add some more environment variables to the current terminal.

We can just add the following exports to terminal (wait don't do it..):

export PATH="/home/linuxbrew/.linuxbrew/bin:/home/linuxbrew/.linuxbrew/sbin${PATH+:$PATH}";

export HOMEBREW_PREFIX="/home/linuxbrew/.linuxbrew";
export HOMEBREW_CELLAR="/home/linuxbrew/.linuxbrew/Cellar";
export HOMEBREW_REPOSITORY="/home/linuxbrew/.linuxbrew/Homebrew";
export MANPATH="/home/linuxbrew/.linuxbrew/share/man${MANPATH+:$MANPATH}:";
export INFOPATH="/home/linuxbrew/.linuxbrew/share/info:${INFOPATH:-}";

Or simply run (If your linuxbrew folder is on other location then /home - change the path):

eval $(/home/linuxbrew/.linuxbrew/bin/brew shellenv)

(*) Because brew command is not yet identified by the current terminal (this is what we're solving right now) we'll have to specify the full path to the brew binary: /home/linuxbrew/.linuxbrew/bin/brew shellenv

Test this step by:

1 ) Run brew from current terminal to see if it identifies the command.

2 ) Run printenv and check if all environment variables were exported and that you see /home/linuxbrew/.linuxbrew/bin:/home/linuxbrew/.linuxbrew/sbin on PATH.

Step 5: Ensure step 4 is running on each terminal

We need to add step 4 to ~/.profile (in case of Debian/Ubuntu):

echo "eval \$($(brew --prefix)/bin/brew shellenv)" >> ~/.profile

For CentOS/Fedora/Red Hat - replace ~/.profile with ~/.bash_profile.

Step 6: Ensure that ~/.profile or ~/.bash_profile are being executed when new terminal is opened

If you executed step 5 and failed to run brew from new terminal - add a test command like echo "Hi!" to ~/.profile or ~/.bash_profile.
If you don't see Hi! when you open a new terminal - go to the terminal preferences and ensure that the attribute of 'run command as login shell' is set.
Read more in here.

Why the installation script installs Homebrew to /home/linuxbrew/.linuxbrew - from here:

The installation script installs Homebrew to /home/linuxbrew/.linuxbrew using sudo if possible and in your home directory at ~/.linuxbrew otherwise. Homebrew does not use sudo after installation.
Using /home/linuxbrew/.linuxbrew allows the use of more binary packages (bottles) than installing in your personal home directory.

The prefix /home/linuxbrew/.linuxbrew was chosen so that users without admin access can ask an admin to create a linuxbrew role account and still benefit from precompiled binaries.

If you do not yourself have admin privileges, consider asking your admin staff to create a linuxbrew role account for you with home directory /home/linuxbrew.

If I have one thing that I love to share with respect to CSS, it's MY FAVE WAY OF CENTERING THINGS ALONG BOTH AXES!!!

Advantages of this method:

1. Full compatibility with browsers that people actually use
2. No tables required
3. Highly reusable for centering any other elements inside their parent
4. Accomodates parents and children with dynamic (changing) dimensions!

I always do this by using 2 classes: One to specify the parent element, whose content will be centered (.centered-wrapper), and the 2nd one to specify which child of the parent is centered (.centered-content). This 2nd class is useful in the case where the parent has multiple children, but only 1 needs to be centered). In this case, body will be the .centered-wrapper, and an inner div will be .centered-content.

<html>
    <head>...</head>
    <body class="centered-wrapper">
        <div class="centered-content">...</div>
    </body>
</html>

The idea for centering will now be to make .centered-content an inline-block. This will easily facilitate horizontal centering, through text-align: center;, and also allows for vertical centering as you shall see.

.centered-wrapper {
    position: relative;
    text-align: center;
}
.centered-wrapper:before {
    content: "";
    position: relative;
    display: inline-block;
    width: 0; height: 100%;
    vertical-align: middle;
}
.centered-content {
    display: inline-block;
    vertical-align: middle;
}

This gives you 2 really reusable classes for centering any child inside of any parent! Just add the .centered-wrapper and .centered-content classes.

So, what's up with that :before element? It facilitates vertical-align: middle; and is necessary because vertical alignment isn't relative to the height of the parent - vertical alignment is relative to the height of the tallest sibling!!!. Therefore, by ensuring that there is a sibling whose height is the parent's height (100% height, 0 width to make it invisible), we know that vertical alignment will be with respect to the parent's height.

One last thing: You need to ensure that your html and body tags are the size of the window so that centering to them is the same as centering to the browser!

html, body {
    width: 100%;
    height: 100%;
    padding: 0;
    margin: 0;
}

Fiddle: https://jsfiddle.net/gershy/g121g72a/

This code is perfect for me:

this.context.beginPath();
this.context.moveTo(data[0].x, data[0].y);
for (let i = 1; i < data.length; i++) {
  this.context.bezierCurveTo(
    data[i - 1].x + (data[i].x - data[i - 1].x) / 2,
    data[i - 1].y,
    data[i - 1].x + (data[i].x - data[i - 1].x) / 2,
    data[i].y,
    data[i].x,
    data[i].y);
}

you have correct smooth line and correct endPoints NOTICE! (y = "canvas height" - y);

This worked for me while searching for value less than or equal than now:

db.collectionName.find({ "dt": { "$lte" : new Date() + "" } });

String.format (https://docs.oracle.com/javase/1.5.0/docs/api/java/util/Formatter.html#syntax)

In your case it will be:

String formatted = String.format("%03d", num);

• 0 - to pad with zeros
• 3 - to set width to 3

You just need to change directories to your app, THEN run bundle install :)

In linux environment:

ip="$(ifconfig eth0 | grep "inet addr:" | awk '{print $2}' | cut -d ':' -f 2)"

or

ip="$(ifconfig eth0 | grep "inet addr:" | awk '{print $2}' | cut -d ':' -f 2)" | echo $ip

example in FreeBSD:

ifconfig re0 | grep -v "inet6" | grep -i "inet" | awk '{print $2}'

If you have more than one IP address configured, you will have more than one IP address in stdout.

As far as I know, Both are same. For cross browser safety you can use window.location rather than document.location.

All modern browsers map document.location to window.location, but I still prefer window.location as that's what I've used since I wrote my first web page. it is more consistent.

you can also see document.location === window.location returns true, which clarifies that both are same.

A neat solution that only uses numpy (not scipy nor the Counter class):

A = np.array([[1,3,4,2,2,7], [5,2,2,1,4,1], [3,3,2,2,1,1]])

np.apply_along_axis(lambda x: np.bincount(x).argmax(), axis=0, arr=A)

array([1, 3, 2, 2, 1, 1])

Or, alternatively, you can take a list comprehension approach:

>>> mylis = ['this is test', 'another test']
>>> [item.upper() for item in mylis]
['THIS IS TEST', 'ANOTHER TEST']

In your project, find Target -> Build Settings -> Other Linker Flags, select Other Linker Flags, press delete(Mac Keyboard)/Backspace(Normal keyboard) to recover the setting. It works for me.

I maintain PDFKit, which also powers pdfmake (already mentioned here). It works in both Node and the browser, and supports a bunch of stuff that other libraries do not:

• Embedding subsetted fonts, with support for unicode.
• Lots of advanced text layout stuff (columns, page breaking, full unicode line breaking, basic rich text, etc.).
• Working on even more font stuff for advanced typography (OpenType/AAT ligatures, contextual substitution, etc.). Coming soon: see the fontkit branch if you're interested.
• More graphics stuff: gradients, etc.
• Built with modern tools like browserify and streams. Usable both in the browser and node.

Check out http://pdfkit.org/ for a full tutorial to see for yourself what PDFKit can do. And for an example of what kinds of documents can be produced, check out the docs as a PDF generated from some Markdown files using PDFKit itself: http://pdfkit.org/docs/guide.pdf.

You can also try it out interactively in the browser here: http://pdfkit.org/demo/browser.html.

If you want to compare files visually you can use:

git difftool

It will start your diff app automatically for each changed file.

PS: If you did not set a diff app, you can do it like in the example below(I use Winmerge):

git config --global merge.tool winmerge
git config --replace --global mergetool.winmerge.cmd "\"C:\Program Files (x86)\WinMerge\WinMergeU.exe\" -e -u -dl \"Base\" -dr \"Mine\" \"$LOCAL\" \"$REMOTE\" \"$MERGED\""
git config --global mergetool.prompt false

Found a site on google explaining some changes, according to the author of the page fb does not allow custom buttons. Heres the website.

Unfortunately, it’s against Facebook’s developer policies, which state:

You must not circumvent our intended limitations on core Facebook features.

The Facebook Connect button is intended to be rendered in FBML, which means it’s only meant to look the way Facebook lets it.

you can simply use onBackPressed();

or if you are using fragment you can use getActivity().onBackPressed()

It seems to be working fine:

List<BigDecimal> list = Arrays.asList(new BigDecimal("24.455"), new BigDecimal("23.455"), new BigDecimal("28.455"), new BigDecimal("20.455"));
System.out.println("Unsorted list: " + list);
final List<BigDecimal> sortedList = list.stream().sorted((o1, o2) -> o1.compareTo(o2)).collect(Collectors.toList());
System.out.println("Sorted list: " + sortedList);

Example Input/Output

Unsorted list: [24.455, 23.455, 28.455, 20.455]
Sorted list: [20.455, 23.455, 24.455, 28.455]

Are you sure you are not verifying list instead of sortedList [in above example] i.e. you are storing the result of stream() in a new List object and verifying that object?

I generally just put a log4j.xml file into src/test/resources and let log4j find it by itself: no code required, the default log4j initialisation will pick it up. (I typically want to set my own loggers to 'DEBUG' anyway)

          .style("fill", color);

      legend.append("text")
          .attr("x", width - 24)
          .attr("y", 9)
          .attr("dy", ".35em")
          .style("text-anchor", "end")
          .text(function(d) { return d; });

    });

}

updateData('data1.csv');

});

You're saying "if it's not set or it's different from add or it's different from delete". You realize that a != x && a != y, with x != y is necessarily false since a cannot be simultaneously two different values.

As of 2016, the following will suffice (you don't even need to embed):

let src = 'https://file-examples.com/wp-content/uploads/2017/11/file_example_MP3_700KB.mp3';
let audio = new Audio(src);
audio.play();

Ideally the email content should be about 550px wide to fit within most email clients preview window. If you know for sure your target market can view bigger then you can design bigger. Loads of email examples over on http://www.beautiful-email-newsletters.com/

div.style yields an object (CSSStyleDeclaration). Since it's an object, you can alternatively use the following:

div.style["top"] = "200px";
div.style["left"] = "200px";

This is useful, for example, if you need to access a "variable" property:

div.style[prop] = "200px";

Inspired by Nelson's and Chris' comments, I've found a way to workaround the same origin policy with a div and an iframe:

HTML:

<div id='div_iframe'><iframe id='frame' src='...'></iframe></div>

CSS:

#div_iframe {
  border-style: inset;
  border-color: grey;
  overflow: scroll;
  height: 500px;
  width: 90%
}

#frame {
  width: 100%;
  height: 1000%;   /* 10x the div height to embrace the whole page */
}

Now suppose I want to skip the first 438 (vertical) pixels of the iframe page, by scrolling to that position.

JS solution:

document.getElementById('div_iframe').scrollTop = 438

JQuery solution:

$('#div_iframe').scrollTop(438)

CSS solution:

#frame { margin-top: -438px }

(Each solution alone is enough, and the effect of the CSS one is a little different since you can't scroll up to see the top of the iframed page.)

There are a few things to change in your edited version:

1. You've taken the suggestion of using document.myform['whichThing'] a bit too literally. Your form is named "aye", so the code to access the whichThing radio buttons should use that name: `document.aye['whichThing'].

2. There's no such thing as an action attribute for the <input> tag. Use onclick instead: <input name="Submit" type="submit" value="Update" onclick="handleClick();return false"/>

3. Obtaining and cancelling an Event object in a browser is a very involved process. It varies a lot by browser type and version. IE and Firefox handle these things very differently, so a simple event.preventDefault() won't work... in fact, the event variable probably won't even be defined because this is an onclick handler from a tag. This is why Stephen above is trying so hard to suggest a framework. I realize you want to know the mechanics, and I recommend google for that. In this case, as a simple workaround, use return false in the onclick tag as in number 2 above (or return false from the function as stephen suggested).

4. Because of #3, get rid of everything not the alert statement in your handler.

The code should now look like:

function handleClick()
      {
        alert("Favorite weird creature: "+getRadioButtonValue(document.aye['whichThing']));
      }
    </script>
  </head>
<body>
    <form name="aye">
      <input name="Submit"  type="submit" value="Update" onclick="handleClick();return false"/>
      Which of the following do you like best?
      <p><input type="radio" name="whichThing" value="slithy toves" />Slithy toves</p>
      <p><input type="radio" name="whichThing" value="borogoves" />Borogoves</p>
      <p><input type="radio" name="whichThing" value="mome raths" />Mome raths</p>
    </form>

Just set
mWebView.setWebChromeClient(new WebChromeClient());

and video plays as normally wont need any custom view.

git reset HEAD

Should do it. If you don't have any uncommitted changes that you care about, then

git reset --hard HEAD

should forcibly reset everything to your last commit. If you do have uncommitted changes, but the first command doesn't work, then save your uncommitted changes with git stash:

git stash
git reset --hard HEAD
git stash pop

If you use storyboards you can use a prototype cell in the tableview to layout your header view. Set an unique id and viewForHeaderInSection you can dequeue the cell with that ID and cast it to a UIView.

pandas uses matplotlib for basic dataframe plots. So, if you are using pandas for basic plot you can use matplotlib for plot customization. However, I propose an alternative method here using seaborn which allows more customization of the plot while not going into the basic level of matplotlib.

Working Code:

import pandas as pd
import seaborn as sns
values = [[1, 2], [2, 5]]
df2 = pd.DataFrame(values, columns=['Type A', 'Type B'], 
                   index=['Index 1', 'Index 2'])
ax= sns.lineplot(data=df2, markers= True)
ax.set(xlabel='xlabel', ylabel='ylabel', title='Video streaming dropout by category') 

In this particular example, it makes no difference. However, the {} in ${} are useful if you want to expand the variable foo in the string

"${foo}bar"

since "$foobar" would instead expand the variable identified by foobar.

Curly braces are also unconditionally required when:

• expanding array elements, as in ${array[42]}
• using parameter expansion operations, as in ${filename%.*} (remove extension)
• expanding positional parameters beyond 9: "$8 $9 ${10} ${11}"

Doing this everywhere, instead of just in potentially ambiguous cases, can be considered good programming practice. This is both for consistency and to avoid surprises like $foo_$bar.jpg, where it's not visually obvious that the underscore becomes part of the variable name.

Since Guava 22, from package com.google.common.primitives you can use three new classes, which have a lower memory footprint compared to ImmutableList.

• ImmutableIntArray
• ImmutableLongArray
• ImmutableDoubleArray

They also have a builder. Example:

int size = 2;
ImmutableLongArray longArray = ImmutableLongArray.builder(size)
  .add(1L)
  .add(2L)
  .build();

or, if the size is known at compile-time:

ImmutableLongArray longArray = ImmutableLongArray.of(1L, 2L);

This is another way of getting an immutable view of an array for Java primitives.

AFAIK, I don't think this is possible with a direct method naming query. You can however use the built in sorting mechanism, using the Sort class. The repository has a findAll(Sort) method that you can pass an instance of Sort to. For example:

import org.springframework.data.domain.Sort;

@Repository
public class StudentServiceImpl implements StudentService {
    @Autowired
    private StudentDAO studentDao;

    @Override
    public List<Student> findAll() {
        return studentDao.findAll(sortByIdAsc());
    }

    private Sort sortByIdAsc() {
        return new Sort(Sort.Direction.ASC, "id");
    }
} 

Trying to write a REST API from scratch is not a simple task. There are many issues to factor and you will need to write a lot of code to process requests and data coming from the caller, authentication, retrieval of data and sending back responses.

Your best bet is to use a framework that already has this functionality ready and tested for you.

Some suggestions are:

Phalcon - REST API building - Easy to use all in one framework with huge performance

Apigility - A one size fits all API handling framework by Zend Technologies

Laravel API Building Tutorial

and many more. Simple searches on Bitbucket/Github will give you a lot of resources to start with.

Our problem solved with updating windows! Our web application is on .Net 4.7.1 and c# 7.0. As we tested in different windowses, we understood that the problem will be solved by updating windows. Indeed, the problem was seen in windows 10 (version 1703) and also in a windows server 2012(not updated in last year). After updating both of them, the problem was solved. In fact, the asp.net minor version(the third part of the clr.dll version in C:\Windows\Microsoft.NET\Framework64\v4.0.30319 ) was changed a bit after the update.

This error will also occur if you call .ps1 file from a .bat file and file path has spaces.

The fix is to make sure there are no spaces in the path of .ps1 file.

Suppose your dataframe is df and you want to change gender from 2 to 1 in participant id 5 then you should determine the row by writing "==" as you can see

 df["rowName", "columnName"] <- value
 df[df$serial.id==5, "gender"] <- 1

First, don't use prints for logging, there is astable, proven and well-thought out stdlib module to do that: logging. You definitely should use it instead.

Second, don't be tempted to do a mess with unrelated tools when there is native and simple approach. Here it is:

log = logging.getLogger(__name__)

try:
    call_code_that_fails()
except MyError:
    log.exception('Any extra info you want to see in your logs')

That's it. You are done now.

Explanation for anyone who is interested in how things work under the hood

What log.exception is actually doing is just a call to log.error (that is, log event with level ERROR) and print traceback then.

Why is it better?

Well, here is some considerations:

• it is just right;
• it is straightforward;
• it is simple.

Why should nobody use traceback or call logger with exc_info=True or get their hands dirty with sys.exc_info?

Well, just because! They all exist for different purposes. For example, traceback.print_exc's output is a little bit different from tracebacks produced by the interpreter itself. If you use it, you will confuse anyone who reads your logs, they will be banging their heads against them.

Passing exc_info=True to log calls is just inappropriate. But, it is useful when catching recoverable errors and you want to log them (using, e.g INFO level) with tracebacks as well, because log.exception produces logs of only one level - ERROR.

And you definitely should avoid messing with sys.exc_info as much as you can. It's just not a public interface, it's an internal one - you can use it if you definitely know what you are doing. It is not intended for just printing exceptions.

You can move the count() inside your sub-select:

SELECT a AS current_a, COUNT(*) AS b,
   ( SELECT COUNT(*) FROM t WHERE a = current_a AND c = 'const' ) as d,
   from t group by a order by b desc

For one of my applications, I either use the computer name if it is non-domain computer, or the domain machine account SID for domain computers. Mark Russinovich talks about it in this blog post, Machine SID:

The final case where SID duplication would be an issue is if a distributed application used machine SIDs to uniquely identify computers. No Microsoft software does so and using the machine SID in that way doesn’t work just for the fact that all DC’s have the same machine SID. Software that relies on unique computer identities either uses computer names or computer Domain SIDs (the SID of the computer accounts in the Domain).

You can access the domain machine account SID via LDAP or System.DirectoryServices.

Some browsers use their own way to read .css files. So the right way to beat this: If you type the command line directly in the .html source code, this beats the .css file, in that way, you told the browser directly what to do and the browser is at position not to read the commands from the .css file. Remember that the commands writen in the .html file is stronger than the command in the .css.

In angular 9, Before tried 'Content-Type': undefined, but it is not worked for me then I tried the below code and It works like charms for a file object

const request = this.http.post(url, data, {
      headers: {
        'Content-Type': 'file'
      },
    });

A GridView is a ViewGroup that displays items in two-dimensional scrolling grid. The items in the grid come from the ListAdapter associated with this view.

This is what you'd want to use (keep using). Because a GridView gets its data from a ListAdapter, the only data loaded in memory will be the one displayed on screen. GridViews, much like ListViews reuse and recycle their views for better performance.

Whereas a GridLayout is a layout that places its children in a rectangular grid.

It was introduced in API level 14, and was recently backported in the Support Library. Its main purpose is to solve alignment and performance problems in other layouts. Check out this tutorial if you want to learn more about GridLayout.

You need to be in the directory of the file and then type the following into the terminal

git reset HEAD .

Assumption is that you need to reset one file only.

1. Make sure you can run powershell scripts (it is disabled by default). Likely you have already done this. http://technet.microsoft.com/en-us/library/ee176949.aspx

   Set-ExecutionPolicy RemoteSigned
   

2. Run this python script on your powershell script helloworld.py:

   # -*- coding: iso-8859-1 -*-
   import subprocess, sys
   
   p = subprocess.Popen(["powershell.exe", 
                 "C:\\Users\\USER\\Desktop\\helloworld.ps1"], 
                 stdout=sys.stdout)
   p.communicate()
   

This code is based on python3.4 (or any 3.x series interpreter), though it should work on python2.x series as well.

In PHP, Encryption and Decryption of a string is possible using one of the Cryptography Extensions called OpenSSL function for encrypt and decrypt.

openssl_encrypt() Function: The openssl_encrypt() function is used to encrypt the data.

Syntax is as follows :

string openssl_encrypt( string $data, string $method, string $key, $options = 0, string $iv, string $tag= NULL, string $aad, int $tag_length = 16 )

Parameters are as follows :

$data: It holds the string or data which need to be encrypted.

$method: The cipher method is adopted using openssl_get_cipher_methods() function.

$key: It holds the encryption key.

$options: It holds the bitwise disjunction of the flags OPENSSL_RAW_DATA and OPENSSL_ZERO_PADDING.

$iv: It holds the initialization vector which is not NULL.

$tag: It holds the authentication tag which is passed by reference when using AEAD cipher mode (GCM or CCM).

$aad: It holds the additional authentication data.

$tag_length: It holds the length of the authentication tag. The length of authentication tag lies between 4 to 16 for GCM mode.

Return Value: It returns the encrypted string on success or FALSE on failure.

openssl_decrypt() Function The openssl_decrypt() function is used to decrypt the data.

Syntax is as follows :

string openssl_decrypt( string $data, string $method, string $key, int $options = 0, string $iv, string $tag, string $aad)

Parameters are as follows :

$data: It holds the string or data which need to be encrypted.

$method: The cipher method is adopted using openssl_get_cipher_methods() function.

$key: It holds the encryption key.

$options: It holds the bitwise disjunction of the flags OPENSSL_RAW_DATA and OPENSSL_ZERO_PADDING.

$iv: It holds the initialization vector which is not NULL.

$tag: It holds the authentication tag using AEAD cipher mode (GCM or CCM). When authentication fails openssl_decrypt() returns FALSE.

$aad: It holds the additional authentication data.

Return Value: It returns the decrypted string on success or FALSE on failure.

Approach: First declare a string and store it into variable and use openssl_encrypt() function to encrypt the given string and use openssl_decrypt() function to descrypt the given string.

You can find the examples at : https://www.geeksforgeeks.org/how-to-encrypt-and-decrypt-a-php-string/

For celery 3.0+:

$ celery purge

To purge a specific queue:

$ celery -Q queue_name purge

List<string> list_lines = new List<string>(lines);
Parallel.ForEach(list_lines, line =>

Justin is dead on. The key point here is that HTML is just a language for describing a document. Once the browser reads it, it's gone. Open tags, close tags, and formatting are all taken care of by the parser and then go away. Any tool that shows you HTML is generating it based on the contents of the document, so it will always be valid.

I had to explain this to another web developer once, and it took a little while for him to accept it.

You can try it for yourself in any JavaScript console:

el = document.createElement('div');
el.innerHTML = "<p>Some text<P>More text";
el.innerHTML; // <p>Some text</p><p>More text</p>

The un-closed tags and uppercase tag names are gone, because that HTML was parsed and discarded after the second line.

The right way to modify the document from JavaScript is with document methods (createElement, appendChild, setAttribute, etc.) and you'll observe that there's no reference to tags or HTML syntax in any of those functions. If you're using document.write, innerHTML, or other HTML-speaking calls to modify your pages, the only way to validate it is to catch what you're putting into them and validate that HTML separately.

That said, the simplest way to get at the HTML representation of the document is this:

document.documentElement.innerHTML

If you are using dj-database-url check the schema in your DATABASES

https://github.com/kennethreitz/dj-database-url

MySQL is

'default': dj_database_url.config(default='mysql://USER:PASSWORD@localhost:PORT/NAME') 

It solves the same error even without the PORT

You set the password with:

mysql -u user -p 

Use a shell script:

#!/bin/bash
# myscript
FOO=bar
somecommand someargs | somecommand2

> ./myscript

I faced the same issue. Just download and install the SQL Server suite from the following link :http://www.microsoft.com/en-US/download/details.aspx?id=42299

restart your SSMS and you should be able to "Register Local Servers" via right-click on "Local Servers Groups", select "tasks", click "register local servers"

For renaming recursively I use the following commands:

find -iname \*.* | rename -v "s/ /-/g"

Just change few snippet(use array_merge function):-

  $options['inputs']=array_merge($options['inputs'], $new_input);

I suppose the easiest and the best solution is using OUTER APPLY. You only use one field with DISTINCT but to retrieve more data about that record, you utilize OUTER APPLY.

To test the solution, execute following query which firstly creates a temp table then retrieves data:

 DECLARE @tblFruit TABLE (tblFruit_ID int, tblFruit_FruitType varchar(10), tblFruit_FruitName varchar(50))
 SET NOCOUNT ON
 INSERT @tblFruit VALUES (1,'Citrus ','Orange')
 INSERT @tblFruit VALUES (2,'Citrus','Lime')
 INSERT @tblFruit VALUES (3,'Citrus','Lemon')
 INSERT @tblFruit VALUES (4,'Seed','Cherry')
 INSERT @tblFruit VALUES (5,'Seed','Banana')
   
SELECT DISTINCT (f.tblFruit_FruitType), outter_f.tblFruit_ID
FROM @tblFruit AS f
OUTER APPLY (
    SELECT TOP(1) *
    FROM @tblFruit AS inner_f
    WHERE inner_f.tblFruit_FruitType = f.tblFruit_FruitType
) AS outter_f

The result will be:

Citrus 1

How to rotate an image around its center:

ImageView view = ... //Initialize ImageView via FindViewById or programatically

RotateAnimation anim = new RotateAnimation(0.0f, 360.0f, Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f);

//Setup anim with desired properties
anim.setInterpolator(new LinearInterpolator());
anim.setRepeatCount(Animation.INFINITE); //Repeat animation indefinitely
anim.setDuration(700); //Put desired duration per anim cycle here, in milliseconds

//Start animation
view.startAnimation(anim); 
//Later on, use view.setAnimation(null) to stop it.

This will cause the image to rotate around its center (0.5 or 50% of its width/height). I am posting this for future readers who get here from Google, as I have, and who wish to rotate the image around its center without defining said center in absolute pixels.

NSMutableArray *array = [[NSMutableArray alloc] initWithObjects:@"First",@"Second", nil];
NSMutableArray *copiedArray = [array mutableCopy];
NSMutableArray *retainedArray = [array retain];

[retainedArray addObject:@"Retained Third"];
[copiedArray addObject:@"Copied Third"];

NSLog(@"array = %@",array);
NSLog(@"Retained Array = %@",retainedArray);
NSLog(@"Copied Array = %@",copiedArray);

array = (
    First,
    Second,
    "Retained Third"
)
Retained Array = (
    First,
    Second,
    "Retained Third"
)
Copied Array = (
    First,
    Second,
    "Copied Third"
)

In order to complement the answer of cantdutchthis and Rodrigo Remedio;

moving_fun <- function(x, w, FUN, ...) {
  # x: a double vector
  # w: the length of the window, i.e., the section of the vector selected to apply FUN
  # FUN: a function that takes a vector and return a summarize value, e.g., mean, sum, etc.
  # Given a double type vector apply a FUN over a moving window from left to the right, 
  #    when a window boundary is not a legal section, i.e. lower_bound and i (upper bound) 
  #    are not contained in the length of the vector, return a NA_real_
  if (w < 1) {
    stop("The length of the window 'w' must be greater than 0")
  }
  output <- x
  for (i in 1:length(x)) {
     # plus 1 because the index is inclusive with the upper_bound 'i'
    lower_bound <- i - w + 1
    if (lower_bound < 1) {
      output[i] <- NA_real_
    } else {
      output[i] <- FUN(x[lower_bound:i, ...])
    }
  }
  output
}

# example
v <- seq(1:10)

# compute a MA(2)
moving_fun(v, 2, mean)

# compute moving sum of two periods
moving_fun(v, 2, sum)

Another common cause of this error on the Mac is Apple's quarantine flag.

ls the directory containing the resource(s) in question. If you see the extended attribute indicator, i.e., the little @ symbol at the end of the permissions block (e.g. -rw-r--r--@ ) then the file could be quarantined.

Try ls -la@e and look for com.apple.quarantine

The following command will remove the quarantine:

xattr -d com.apple.quarantine /path/to/file

Don't know what bugs can hide here, but I use this:

var some_string_with_extra_spaces="   goes here    "
console.log(some_string_with_extra_spaces.match(/\S.*\S|\S/)[0])

Or this, if text contain enters:

console.log(some_string_with_extra_spaces.match(/\S[\s\S]*\S|\S/)[0])

Another try:

console.log(some_string_with_extra_spaces.match(/^\s*(.*?)\s*$/)[1])

How about writing out some escape sequences?

echo "\033[01;31m Request has been sent. Please wait for my reply! \033[0m";

Won't work through browser though, only from console ;))

This should work fine for you.

Write this code in the Page_Load event of the page.

string ID = Request.QueryString["id"].ToString();
Response.Redirect("http://www.example.com/rendernews.php?id=" + ID);

It may not be quite what you want, since it's not a standard command on anyone's systems, but since my program should work fine on POSIX systems (if compiled), I'll mention it anyway. If you have the ability to compile or add programs on the machine in question, it should work.

I've used it without issue for about a year now, but it could be that it won't handle some edge cases. Most specifically, I have no idea what it would do with newlines in strings; a case for \\n might need to be added. This list of characters is not authoritative, but I believe it covers everything else.

I wrote this specifically as a 'helper' program so I could make a wrapper for things like scp commands.

It can likely be implemented as a shell function as well

I therefore present escapify.c. I use it like so:

scp user@host:"$(escapify "/this/path/needs to be escaped/file.c")" destination_file.c

PLEASE NOTE: I made this program for my own personal use. It also will (probably wrongly) assume that if it is given more than one argument that it should just print an unescaped space and continue on. This means that it can be used to pass multiple escaped arguments correctly, but could be seen as unwanted behavior by some.

You've almost done it. However setting flex: 0 0 <basis> declaration to the columns would prevent them from growing/shrinking; And the <basis> parameter would define the width of columns.

In addition, you could use CSS3 calc() expression to specify the height of columns with the respect to the height of the header.

#productShowcaseTitle {
  flex: 0 0 100%; /* Let it fill the entire space horizontally */
  height: 100px;
}

#productShowcaseDetail,
#productShowcaseThumbnailContainer {
  height: calc(100% - 100px); /* excluding the height of the header */
}

#productShowcaseContainer {_x000D_
  display: flex;_x000D_
  flex-flow: row wrap;_x000D_
_x000D_
  height: 600px;_x000D_
  width: 580px;_x000D_
}_x000D_
_x000D_
#productShowcaseTitle {_x000D_
  flex: 0 0 100%; /* Let it fill the entire space horizontally */_x000D_
  height: 100px;_x000D_
  background-color: silver;_x000D_
}_x000D_
_x000D_
#productShowcaseDetail {_x000D_
  flex: 0 0 66%; /* ~ 2 * 33.33% */_x000D_
  height: calc(100% - 100px); /* excluding the height of the header */_x000D_
  background-color: lightgray;_x000D_
}_x000D_
_x000D_
#productShowcaseThumbnailContainer {_x000D_
  flex: 0 0 34%;  /* ~ 33.33% */_x000D_
  height: calc(100% - 100px); /* excluding the height of the header */_x000D_
  background-color: black;_x000D_

(Vendor prefixes omitted due to brevity)

Alternatively, if you could change your markup e.g. wrapping the columns by an additional <div> element, it would be achieved without using calc() as follows:

<div class="contentContainer"> <!-- Added wrapper -->
    <div id="productShowcaseDetail"></div>
    <div id="productShowcaseThumbnailContainer"></div>
</div>

#productShowcaseContainer {
  display: flex;
  flex-direction: column;
  height: 600px; width: 580px;
}

.contentContainer { display: flex; flex: 1; }
#productShowcaseDetail { flex: 3; }
#productShowcaseThumbnailContainer { flex: 2; }

You'll need to add the other repository as a remote, then fetch its changes. From there you see the commit and you can cherry-pick it.

Like that:

git remote add other https://example.link/repository.git
git fetch other

Now you have all the information to simply do git cherry-pick.

More info about working with remotes here: https://git-scm.com/book/en/v2/Git-Basics-Working-with-Remotes

based on fortran's answer, this is a recusive version that uses a StringBuilder:

public static void repeat(StringBuilder stringBuilder, String s, int times) {
    if (times > 0) {
        repeat(stringBuilder.append(s), s, times - 1);
    }
}

public static String repeat(String s, int times) {
    StringBuilder stringBuilder = new StringBuilder(s.length() * times);
    repeat(stringBuilder, s, times);
    return stringBuilder.toString();
}

CSS isn't going to be able to call other elements like that, you'll need to use JavaScript to reach beyond a child or sibling selector.

You could try something like this:

<a>Some Link
<div><img src="/you/image" /></div>
</a>

then...

a>div { display: none; }
a:hover>div { display: block; }

I had the same issue before. Try this answer here, it works on my site.

$(function(){
  var current_page_URL = location.href;
  $( "a" ).each(function() {
     if ($(this).attr("href") !== "#") {
       var target_URL = $(this).prop("href");
       if (target_URL == current_page_URL) {
          $('nav a').parents('li, ul').removeClass('active');
          $(this).parent('li').addClass('active');
          return false;
       }
     }
  });
});

I noticed that whenever I would start the form tag inside a div the subsequent div siblings would not be part of the form when I inspect (chrome inspect) henceforth my form would never submit.

<div>
<form>
<input name='1st input'/>
</div>
<div>
<input name='2nd input'/>
</div>
<input type='submit'/>
</form>

I figured that if I put the form tag outside the DIVs it worked. The form tag should be placed at the start of the parent DIV. Like shown below.

<form>
<div>
<input name='1st input'/>
</div>
<div>
<input name='2nd input'/>
</div>
<input type='submit'/>
</form>

Acoording to RFC 2046 (Multipurpose Internet Mail Extensions):

The recommended action for an implementation that receives an
"application/octet-stream" entity is to simply offer to put the data in a file

So I'd go for that one.

The problem with other proposed solutions is that they will either drop characters that cannot be directly mapped to ASCII, or replace them with a marker character like ?.

You might desire to have for example accented characters converted to that same character without the accent. There are a couple of tricks to do this (including building a static mapping table yourself or leveraging existing 'normalization' defined for unicode), but those methods are far from complete.

Your best bet is using the junidecode library, which cannot be complete either but incorporates a lot of experience in the most sane way of transliterating Unicode to ASCII.

'\r' = carriage return and '\n' = line feed.

In fact, there are some different behaviors when you use them in different OSes. On Unix it is '\n', but it is '\r''\n' on Windows.

On Linux, and Unix in general, "r" and "rb" are the same. More specifically, a FILE pointer obtained by fopen()ing a file in in text mode and in binary mode behaves the same way on Unixes. On windows, and in general, on systems that use more than one character to represent "newlines", a file opened in text mode behaves as if all those characters are just one character, '\n'.

If you want to portably read/write text files on any system, use "r", and "w" in fopen(). That will guarantee that the files are written and read properly. If you are opening a binary file, use "rb" and "wb", so that an unfortunate newline-translation doesn't mess your data.

Note that a consequence of the underlying system doing the newline translation for you is that you can't determine the number of bytes you can read from a file using fseek(file, 0, SEEK_END).

Finally, see What's the difference between text and binary I/O? on comp.lang.c FAQs.

I hope, I answered your Question.

You can also use jq to track down the array within the returned json and then pipe that in to a second jq call to get its length. Suppose it was in a property called records, like {"records":[...]}.

$ curl https://my-source-of-json.com/list | jq -r '.records' | jq length

I had the same problem. Microsoft.Owin.Host.SystemWeb package was installed but during the installation NuGet was not able to add the dll as a reference for some reason. Make sure your project has that reference. If not you can try to reinstall:

update-package Microsoft.Owin.Host.SystemWeb -reinstall

I had an error like below on reinstall but somehow it worked:

System call failed. (Exception from HRESULT: 0x80010100 (RPC_E_SYS_CALL_FAILED))

I wrote an informative blog article about this topic: How to Extract IPv4 and IPv6 IP Addresses from Plain Text Using Regex.

In the article there's a detailed guide of the most common different patterns for IPs, often required to be extracted and isolated from plain text using regular expressions.
This guide is based on CodVerter's IP Extractor source code tool for handling IP addresses extraction and detection when necessary.

If you wish to validate and capture IPv4 Address this pattern can do the job:

\b(?:(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)[.]){3}(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\b

or to validate and capture IPv4 Address with Prefix ("slash notation"):

\b(?:(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)[.]){3}(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?/[0-9]{1,2})\b

or to capture subnet mask or wildcard mask:

(255|254|252|248|240|224|192|128|0)[.](255|254|252|248|240|224|192|128|0)[.](255|254|252|248|240|224|192|128|0)[.](255|254|252|248|240|224|192|128|0)

or to filter out subnet mask addresses you do it with regex negative lookahead:

\b((?!(255|254|252|248|240|224|192|128|0)[.](255|254|252|248|240|224|192|128|0)[.](255|254|252|248|240|224|192|128|0)[.](255|254|252|248|240|224|192|128|0)))(?:(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)[.]){3}(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\b

For IPv6 validation you can go to the article link I have added at the top of this answer.
Here is an example for capturing all the common patterns (taken from CodVerter`s IP Extractor Help Sample):

If you wish you can test the IPv4 regex here.

I tried many solutions but only one worked for me, the install of Microsoft Visual Studio 2008 Express C++.

I got this issue with a Python 2.7 module written in C (yEnc, which has other issues with MS VS). Note that Python 2.7 is built with MS VS 2008 version, not 2010!

Despite the fact it's free, it is quite hard to find since MS is promoting VS 2010. Still, the MSDN official very direct links are still working: check https://stackoverflow.com/a/15319069/2227298 for download links.

$(document).ready(function(){
$("#HoursEntry").change(function(){
var HoursEntry = $(#HoursEntry option:selected).val();
if(HoursEntry == "")
{
$("#HoursEntry").html("Please select");
return false;
}
});
});

I think it is not totally unrelated but did you consider canvas? something like Process JS can make it simpler.

You can do this:

alert([
  "afshin", 
  "saeed", 
  "larry",
  "sasha",
  "boby",
  "jhon",
  "anna",
  // ...
].includes(varName)? 'Hey' : 'Default case')

or just a single line of code:

alert(["afshin", "saeed", "larry",...].includes(varName)? 'Hey' : 'Default case')

a little improvement from ErikE's answer

Guys it has very simple solution

https://developers.google.com/instance-id/guides/android-implementation#generate_a_token

Note: If your app used tokens that were deleted by deleteInstanceID, your app will need to generate replacement tokens.

In stead of deleting instance Id, delete only token:

String authorizedEntity = PROJECT_ID;
String scope = "GCM";
InstanceID.getInstance(context).deleteToken(authorizedEntity,scope);

As written by Dave Butenhof himself:

"The biggest of all the big problems with recursive mutexes is that they encourage you to completely lose track of your locking scheme and scope. This is deadly. Evil. It's the "thread eater". You hold locks for the absolutely shortest possible time. Period. Always. If you're calling something with a lock held simply because you don't know it's held, or because you don't know whether the callee needs the mutex, then you're holding it too long. You're aiming a shotgun at your application and pulling the trigger. You presumably started using threads to get concurrency; but you've just PREVENTED concurrency."

you could do this, if you want to use the old syntax (or don't want to rewrite every template)

@for $i from 1 through $grid-columns {
  @include media-breakpoint-up(xs) {
    .col-xs-#{$i} {
      @include make-col-ready();
      @include make-col($i);
    }
  }
}

Another option: Do not float your right column; just give it a left margin to move it beyond the float. You'll need a hack or two to fix IE6, but that's the basic idea.

Solving this will require a platform specific solution. Look for opendir() on unix/linux or FindFirstFile() on Windows. Or, there are many libraries that will handle the platform specific part for you.

Here is how one can do it. I will give an example with joining so that it becomes super clear to someone.

$products = DB::table('products AS pr')
        ->leftJoin('product_families AS pf', 'pf.id', '=', 'pr.product_family_id')
        ->select('pr.id as id', 'pf.name as product_family_name', 'pf.id as product_family_id')
        ->orderBy('pr.id', 'desc')
        ->get();

Hope this helps.

If you use Robert Harder's Base64 utility, then you can do:

InputStream is = new Base64.InputStream(cph);

Or with sun's JRE, you can do:

InputStream is = new
com.sun.xml.internal.messaging.saaj.packaging.mime.util.BASE64DecoderStream(cph)

However don't rely on that class continuing to be a part of the JRE, or even continuing to do what it seems to do today. Sun say not to use it.

There are other Stack Overflow questions about Base64 decoding, such as this one.

Several years too late:

Just for completeness I want to give yet another answer:

First, go to Excel-Options -> Formulas and enable R1C1 references. Then use

  =CELL("width", RC)

RC always refers the current Row, current Column, i.e. "this cell".

Rick Teachey's solution is basically a tweak to make the same possible in A1 reference style (see also GSerg's comment to Joey's answer and note his comment to Patrick McDonald's answer).

== is an equality test. It checks whether the right hand side and the left hand side are equal objects (according to their __eq__ or __cmp__ methods.)

is is an identity test. It checks whether the right hand side and the left hand side are the very same object. No methodcalls are done, objects can't influence the is operation.

You use is (and is not) for singletons, like None, where you don't care about objects that might want to pretend to be None or where you want to protect against objects breaking when being compared against None.

The function scipy.signal.find_peaks, as its name suggests, is useful for this. But it's important to understand well its parameters width, threshold, distance and above all prominence to get a good peak extraction.

According to my tests and the documentation, the concept of prominence is "the useful concept" to keep the good peaks, and discard the noisy peaks.

What is (topographic) prominence? It is "the minimum height necessary to descend to get from the summit to any higher terrain", as it can be seen here:

The idea is:

The higher the prominence, the more "important" the peak is.

Test:

I used a (noisy) frequency-varying sinusoid on purpose because it shows many difficulties. We can see that the width parameter is not very useful here because if you set a minimum width too high, then it won't be able to track very close peaks in the high frequency part. If you set width too low, you would have many unwanted peaks in the left part of the signal. Same problem with distance. threshold only compares with the direct neighbours, which is not useful here. prominence is the one that gives the best solution. Note that you can combine many of these parameters!

Code:

import numpy as np
import matplotlib.pyplot as plt 
from scipy.signal import find_peaks

x = np.sin(2*np.pi*(2**np.linspace(2,10,1000))*np.arange(1000)/48000) + np.random.normal(0, 1, 1000) * 0.15
peaks, _ = find_peaks(x, distance=20)
peaks2, _ = find_peaks(x, prominence=1)      # BEST!
peaks3, _ = find_peaks(x, width=20)
peaks4, _ = find_peaks(x, threshold=0.4)     # Required vertical distance to its direct neighbouring samples, pretty useless
plt.subplot(2, 2, 1)
plt.plot(peaks, x[peaks], "xr"); plt.plot(x); plt.legend(['distance'])
plt.subplot(2, 2, 2)
plt.plot(peaks2, x[peaks2], "ob"); plt.plot(x); plt.legend(['prominence'])
plt.subplot(2, 2, 3)
plt.plot(peaks3, x[peaks3], "vg"); plt.plot(x); plt.legend(['width'])
plt.subplot(2, 2, 4)
plt.plot(peaks4, x[peaks4], "xk"); plt.plot(x); plt.legend(['threshold'])
plt.show()

Another approach to address the issue is to use ConstraintLayout inside ScrollView:

<ScrollView>
  <ConstraintLayout> (this is the only child of ScrollView)
    <...Some Views...>
    <RecyclerView> (layout_height=wrap_content)
    <...Some Other Views...>

But I would still stick to the androidx.core.widget.NestedScrollView approach, proposed by Yang Peiyong.

I had the same problem when I deployed my application to test PC. The problem was development PC had msvcp110d.dll and msvcr110d.dll but not the test PC.

I added "Visual Studio C++ 11.0 DebugCRT (x86)" merge module in InstalledSheild and it worked. Hope this will be helpful for someone else.

Also, it has to be noted that if you're using your_tensor.assign(), then the tf.global_variables_initializer need not be called explicitly since the assign operation does it for you in the background.

Example:

In [212]: w = tf.Variable(12)
In [213]: w_new = w.assign(34)

In [214]: with tf.Session() as sess:
     ...:     sess.run(w_new)
     ...:     print(w_new.eval())

# output
34 

However, this will not initialize all variables, but it will only initialize the variable on which assign was executed on.

I faced the same error, but only with files cloned from git that were assigned to a proprietary plugin. I realized that even after cloning the files from git, I needed to create a new project or import a project in eclipse and this resolved the error.

The easy way:

myInt *= -1;

You are using the wrong format tokens when parsing your input. You should use ddd for an abbreviation of the name of day of the week, DD for day of the month, MMM for an abbreviation of the month's name, YYYY for the year, hh for the 1-12 hour, mm for minutes and A for AM/PM. See moment(String, String) docs.

Here is a working live sample:

console.log( moment('Mon 03-Jul-2017, 11:00 AM', 'ddd DD-MMM-YYYY, hh:mm A').format('hh:mm A') );_x000D_
console.log( moment('Mon 03-Jul-2017, 11:00 PM', 'ddd DD-MMM-YYYY, hh:mm A').format('hh:mm A') );

Since there were no exact answers to my question, I made some investigation why my code doesn't work when there are other solutions that works, and decided to post what I found to complete the subject.
As it turns out:

"ssh uses direct TTY access to make sure that the password is indeed issued by an interactive keyboard user." sshpass manpage

which answers the question, why the pipes don't work in this case. The obvious solution was to create conditions so that ssh "thought" that it is run in the regular terminal and since it may be accomplished by simple posix functions, it is beyond what simple bash offers.

Because your delimiter is ", " you could use any of the following:

public class StringDelim {

    public static void removeBrackets(String string) {
        System.out.println(string.substring(1, string.length() - 1));
    }

    public static void main(String... args) {
        // Array.toString() example
        String [] arr = {"Hi" , "My", "name", "is", "br3nt"};
        String string = Arrays.toString(arr);
        removeBrackets(string);

        // List#toString() example
        List<String> list = new ArrayList<String>();
        list.add("Hi");
        list.add("My");
        list.add("name");
        list.add("is");
        list.add("br3nt");
        string = list.toString();
        removeBrackets(string);

        // Map#values().toString() example
        Map<String, String> map = new LinkedHashMap<String, String>();
        map.put("1", "Hi");
        map.put("2", "My");
        map.put("3", "name");
        map.put("4", "is");
        map.put("5", "br3nt");
        System.out.println(map.values().toString());
        removeBrackets(string);

        // Enum#toString() example
        EnumSet<Days> set = EnumSet.allOf(Days.class);
        string = set.toString();
        removeBrackets(string);
    }

    public enum Days {
        MON("Monday"),
        TUE("Tuesday"),
        WED("Wednesday"),
        THU("Thursday"),
        FRI("Friday"),
        SAT("Saturday"),
        SUN("Sunday");

        private final String day;

        Days(String day) {this.day = day;}
        public String toString() {return this.day;}
    }
}

If your delimiter is ANYTHING else then this isn't going to work for you.

Sometimes the easiest way to fix this issue is to make a new branch from the place where you know the code is good. Then you can leave the errant branch history alone in case you need to cherry-pick other commits from it later. This also ensures you did not lose any commit history.

From your local errant branch:

git log

copy the commit hash that you wanted the branch to be at and exit the git log

git checkout theHashYouJustCopied
git checkout -b your_new_awesome_branch

Now you have a new branch just the way you want it.

If you also needed to keep a specific commit from the errant branch that is not on your new branch, you can just cherry-pick that specific commit you need:

git checkout the_errant_branch
git log

Copy the commit hash of the one commit you need to pull into the good branch and exit the git log.

git checkout your_new_awesome_branch
git cherry-pick theHashYouJustCopied

Pat yourself on the back.

You can use the com.google.common.io.Resources.getResource to read the url of file and then get the file content using java.nio.file.Files to read the content of file.

URL urlPath = Resources.getResource("src/main/resource");
List<String> multilineContent= Files.readAllLines(Paths.get(urlPath.toURI()));

I had the same problem - solved it by setting display_errors = On in both php.ini files.

/etc/php5/apache2/php.ini
/etc/php5/cli/php.ini

Then restarting Apache:

sudo /etc/init.d/apache2 restart

Hope this helps.

Generally you would need some form of post build tool to perform an assembly merge like you are describing. There is a free tool called Eazfuscator (eazfuscator.blogspot.com/) which is designed for bytecode mangling that also handles assembly merging. You can add this into a post build command line with Visual Studio to merge your assemblies, but your mileage will vary due to issues that will arise in any non trival assembly merging scenarios.

You could also check to see if the build make untility NANT has the ability to merge assemblies after building, but I am not familiar enough with NANT myself to say whether the functionality is built in or not.

There are also many many Visual Studio plugins that will perform assembly merging as part of building the application.

Alternatively if you don't need this to be done automatically, there are a number of tools like ILMerge that will merge .net assemblies into a single file.

The biggest issue I've had with merging assemblies is if they use any similar namespaces. Or worse, reference different versions of the same dll (my problems were generally with the NUnit dll files).

There are a few efficient ways to implement this. Let's start with required imports:

from pyspark.sql.functions import col, expr, when

You can use Hive IF function inside expr:

new_column_1 = expr(
    """IF(fruit1 IS NULL OR fruit2 IS NULL, 3, IF(fruit1 = fruit2, 1, 0))"""
)

or when + otherwise:

new_column_2 = when(
    col("fruit1").isNull() | col("fruit2").isNull(), 3
).when(col("fruit1") == col("fruit2"), 1).otherwise(0)

Finally you could use following trick:

from pyspark.sql.functions import coalesce, lit

new_column_3 = coalesce((col("fruit1") == col("fruit2")).cast("int"), lit(3))

With example data:

df = sc.parallelize([
    ("orange", "apple"), ("kiwi", None), (None, "banana"), 
    ("mango", "mango"), (None, None)
]).toDF(["fruit1", "fruit2"])

you can use this as follows:

(df
    .withColumn("new_column_1", new_column_1)
    .withColumn("new_column_2", new_column_2)
    .withColumn("new_column_3", new_column_3))

and the result is:

+------+------+------------+------------+------------+
|fruit1|fruit2|new_column_1|new_column_2|new_column_3|
+------+------+------------+------------+------------+
|orange| apple|           0|           0|           0|
|  kiwi|  null|           3|           3|           3|
|  null|banana|           3|           3|           3|
| mango| mango|           1|           1|           1|
|  null|  null|           3|           3|           3|
+------+------+------------+------------+------------+

Actual for EntityFrameworkCore 3.1.3:

some solution in OnModelCreating:

var fixDecimalDatas = new List<Tuple<Type, Type, string>>();
foreach (var entityType in builder.Model.GetEntityTypes())
{
    foreach (var property in entityType.GetProperties())
    {
        if (Type.GetTypeCode(property.ClrType) == TypeCode.Decimal)
        {
            fixDecimalDatas.Add(new Tuple<Type, Type, string>(entityType.ClrType, property.ClrType, property.GetColumnName()));
        }
    }
}

foreach (var item in fixDecimalDatas)
{
    builder.Entity(item.Item1).Property(item.Item2, item.Item3).HasColumnType("decimal(18,4)");
}

//custom decimal nullable:
builder.Entity<SomePerfectEntity>().Property(x => x.IsBeautiful).HasColumnType("decimal(18,4)");

If you are planning to draw a lot of pixel, it's a lot more efficient to use the image data of the canvas to do pixel drawing.

var canvas = document.getElementById("myCanvas");
var canvasWidth = canvas.width;
var canvasHeight = canvas.height;
var ctx = canvas.getContext("2d");
var canvasData = ctx.getImageData(0, 0, canvasWidth, canvasHeight);

// That's how you define the value of a pixel //
function drawPixel (x, y, r, g, b, a) {
    var index = (x + y * canvasWidth) * 4;

    canvasData.data[index + 0] = r;
    canvasData.data[index + 1] = g;
    canvasData.data[index + 2] = b;
    canvasData.data[index + 3] = a;
}

// That's how you update the canvas, so that your //
// modification are taken in consideration //
function updateCanvas() {
    ctx.putImageData(canvasData, 0, 0);
}

Then, you can use it in this way :

drawPixel(1, 1, 255, 0, 0, 255);
drawPixel(1, 2, 255, 0, 0, 255);
drawPixel(1, 3, 255, 0, 0, 255);
updateCanvas();

For more information, you can take a look at this Mozilla blog post : http://hacks.mozilla.org/2009/06/pushing-pixels-with-canvas/

If an object's property may refer to some other object then you can test that for undefined before trying to use its properties:

if (thing && thing.foo)
   alert(thing.foo.bar);

I could update my answer to better reflect your situation if you show some actual code, but possibly something like this:

function someFunc(parameterName) {
   if (parameterName && parameterName.foo)
       alert(parameterName.foo.bar);
}

You can modify the output format:

>>> a = 13.95
>>> a
13.949999999999999
>>> print "%.2f" % a
13.95

I find the simple solution

pylab.ticklabel_format(axis='y',style='sci',scilimits=(1,4))

The getTimezoneOffset() method in JavaScript, in a browser, returns the number of minutes offset from the 00:00 time zone. For example, America/New_York time zone in Daylight Savings (DST) returns the number 300. 300 minutes is 5 hours difference from zero. 300 minutes divided by 60 minutes is 5 hours. Every time zone is compared to the zero time zone, +00:00 / Etc/GMT / Greenwich time.

MDN Web Docs

The next thing that you must know, is that the offset has the opposite sign of the actual time zone.

Information about time zones is maintained by the Internet Assigned Numbers Authority (iana)

iana time zones

A nicely formatted table of Time Zones is supplied by joda.org

joda-time Time Zones

+00:00 or Etc/GMT is Greenwich time

All time zones are offset from +00:00 / "Etc/GMT" / Greenwich time

Daylight Savings Time is always an earlier time than the "regular" time in the summer. You set your clocks back in the fall season. ("Fall Back" slogan to remember what to do)

So, America/New_York time in Daylight Savings (winter) is one hour before the regular time. So, for example, what was normally 5 p.m. in the afternoon in New York city in the summer, is now 4 p.m. America/New_York time in Daylight Savings. The name "America/New_York" time is a "Long Format" time zone name. The east coast of the U.S typically calls their time zone Eastern Standard Time (EST)

If you want to compare today's time zone offset to the time zone offset of some other date, you need to know that mathematical sign (+/- "Positive / Negative") of the time zone offset is the opposite of the time zone.

Look at the time zone table at joda.org and find the time zone for "America/New_York" It will have a negative sign in front of the Standard Offset.

The earth rotates counter-clockwise on it's axis. A person watch the sunrise in Greenwich sees the sunrise 5 hours before someone in New York City will see the sunrise. And someone on the West Coast of the U.S. will see the sunrise after someone on the East Coast of the U.S. sees the sunrise.

There's a reason why you need to know all of this. So that you'll be able to logically determine whether some JavaScript code is getting the DST status correctly or not, without needing to test every time zone at different times of the year.

Imagine that it's November in New York City, and the clocks have been set back an hour. In the summer in New York City, the offset is 240 minutes or 4 hours.

You can test this by creating a date that is in July and then getting the offset.

var July_Date = new Date(2017, 6, 1);
var july_Timezone_OffSet = July_Date.getTimezoneOffset();

console.log('july_Timezone_OffSet: ' + july_Timezone_OffSet)

What will print to the browser's developer tools console log?

Answer is: 240

So, now you can create a date in January and see what your browser returns for a time zone offset for the winter season.

var Jan_Date = new Date(2017, 0, 1);//Month is zero indexed - Jan is zero
var jan_Timezone_OffSet = Jan_Date.getTimezoneOffset();

console.log('jan_Timezone_OffSet: ' + jan_Timezone_OffSet)

Answer is: 300

Obviously 300 is bigger than 240. So, what does this mean? Should you write code that tests for the winter offset being bigger than the summer offset? Or the summer offset less than the winter offset? If there is a difference between the summer and winter time zone offsets, then you can assume that DST is being used for this time zone. But that doesn't tell you if today is using DST for the browsers time zone. So, you'll need to get the time zone offset for today.

var today = new Date();
var todaysTimeZone = today.getTimezoneOffset();

console.log('todaysTimeZone : ' + todaysTimeZone)

Answer is: ? - Depends on the time of year

If today's time zone offset and the summer time zone offset is the same, AND the summer and winter time zone offsets are different, then by logical deduction, today must be NOT be in DST.

Can you omit comparing the summer and winter time zone offsets, (To know if DST is used for this time zone) and just compare today's time zone offset to the summer TZ offset, and always get the correct answer?

today's TZ Offset !== Summer TZ Offset

Well, is today in the winter or summer? If you knew that then you could apply the following logic:

if ( it_is_winter && ( todays_TZ_Offset !== summer_TZ_Offset) {
  var are_We_In_DST = true;
}

But the problem is, that you don't know if today's date is in winter or summer. Every time zone can have it's own rules for when DST starts and stops. You'd need to keep track of every time zone's rules for every time zone in the world. So, if there is a better and easier way then you might as well do it the better and easier way.

What we are left with, is that you need to know if this time zone uses DST, and then compare today's time zone offset with the summer time zone offset. That will always give you a reliable answer.

The final logic is:

if ( DST_Is_Used_In_This_Time_Zone && ( todays_TZ_Offset !== summer_TZ_Offset) {
  var are_We_In_DST = true;
}

Function to determine if the time zone in the browser uses DST:

function is_DST_Used_In_This_TimeZone() {
  var Jan_Date, jan_Timezone_OffSet, July_Date, july_Timezone_OffSet 
      offsetsNotEqual, thisYear, today;

  today = new Date();//Create a date object that is now
  thisYear = today.getFullYear();//Get the year as a number

  Jan_Date = new Date(thisYear, 0, 1);//Month is zero indexed - Jan is zero
  jan_Timezone_OffSet = Jan_Date.getTimezoneOffset();

  console.log('jan_Timezone_OffSet: ' + jan_Timezone_OffSet)

  July_Date = new Date(thisYear, 6, 1);
  july_Timezone_OffSet = July_Date.getTimezoneOffset();

  console.log('july_Timezone_OffSet: ' + july_Timezone_OffSet)

  offsetsNotEqual = july_Timezone_OffSet !== jan_Timezone_OffSet;//True if not equal

  console.log('offsetsNotEqual: ' + offsetsNotEqual);

  return offsetsNotEqual;//If the offsets are not equal for summer and
       //winter then the only possible reason is that DST is used for
       //this time zone
}

 grouped=df.groupby(['Team','Year'])['W'].count().reset_index()

Just as there are printer drivers that do not connect to a printer at all but rather write to a PDF file, analogously there are virtual audio drivers available that do not connect to a physical microphone at all but can pipe input from other sources such as files or other programs.

I hope I'm not breaking any rules by recommending free/donation software, but VB-Audio Virtual Cable should let you create a pair of virtual input and output audio devices. Then you could play an MP3 into the virtual output device and then set the virtual input device as your "microphone". In theory I think that should work.

If all else fails, you could always roll your own virtual audio driver. Microsoft provides some sample code but unfortunately it is not applicable to the older Windows XP audio model. There is probably sample code available for XP too.

I would suggest going the lxml route and using xpath.

from lxml import etree
# data is the variable containing the html
data = etree.HTML(data)
anchor = data.xpath('//a[@class="title"]/text()')

An example that uses RecursiveDirectoryIterator class, it's a convenient way to iterate recursively over filesystem.

$output = array();
foreach( new RecursiveIteratorIterator( 
    new RecursiveDirectoryIterator( 'path', FilesystemIterator::SKIP_DOTS | FilesystemIterator::UNIX_PATHS ) ) as $value ) {      
        if ( $value->isFile() ) {
            $output[] = array( $value->getMTime(), $value->getRealPath() );
        }
}

usort ( $output, function( $a, $b ) {
    return $a[0] > $b[0];
});

Yes, it does. From the AdMob page:

The Mobile Ads SDK for iOS utilizes Apple's advertising identifier (IDFA). The SDK uses IDFA under the guidelines laid out in the iOS developer program license agreement. You must ensure you are in compliance with the iOS developer program license agreement policies governing the use of this identifier.

I know this is an old thread, but for others looking, the above solutions are maybe not as good as the following, instead of checking change events, check the input events.

$("#myInput").on("input", function() {
    // Print entered value in a div box
    $("#result").text($(this).val());
});

Also, consider to use a repository manager such as Nexus and configure all your repositories there.

You may try this way. just use a function to get your object

def get_object(self, id):
    try:
        return UniversityDetails.objects.get(email__exact=email)
    except UniversityDetails.DoesNotExist:
        return False

From the command line, it's simply:

printf "compute sha1" | openssl sha1

You can invoke the library like this:

#include <stdio.h>
#include <string.h>
#include <openssl/sha.h>

int main()
{
    unsigned char ibuf[] = "compute sha1";
    unsigned char obuf[20];

    SHA1(ibuf, strlen(ibuf), obuf);

    int i;
    for (i = 0; i < 20; i++) {
        printf("%02x ", obuf[i]);
    }
    printf("\n");

    return 0;
}

When doing a clean HTML Structure, you can use this.

//Jquery Code_x000D_
$('a#link_1').click(function(e){_x000D_
  e . preventDefault () ;_x000D_
  var a = e . target ;_x000D_
  window . open ( '_top' , a . getAttribute ('href') ) ;_x000D_
});_x000D_
_x000D_
//Normal Code_x000D_
element = document . getElementById ( 'link_1' ) ;_x000D_
element . onClick = function (e) {_x000D_
  e . preventDefault () ;_x000D_
  _x000D_
  window . open ( '_top' , element . getAttribute ('href') ) ;_x000D_
} ;

<a href="#Foo" id="link_1">Do it!</a>

Of course, the proper way to write a Makefile is to actually document which targets depend on which sources. In the trivial case, the proposed solution will make foo depend on itself, but of course, make is smart enough to drop a circular dependency. But if you add a temporary file to your directory, it will "magically" become part of the dependency chain. Better to create an explicit list of dependencies once and for all, perhaps via a script.

GNU make knows how to run gcc to produce an executable out of a set of .c and .h files, so maybe all you really need amounts to

foo: $(wildcard *.h) $(wildcard *.c)

Date.now() returns a unix timestamp in milliseconds.

const now = Date.now(); // Unix timestamp in milliseconds_x000D_
console.log( now );

Prior to ECMAScript5 (I.E. Internet Explorer 8 and older) you needed to construct a Date object, from which there are several ways to get a unix timestamp in milliseconds:

console.log( +new Date );_x000D_
console.log( (new Date).getTime() );_x000D_
console.log( (new Date).valueOf() );

I got the solution for onunload in all browsers except Opera by changing the Ajax asynchronous request into synchronous request.

xmlhttp.open("POST","LogoutAction",false);

It works well for all browsers except Opera.

I had the same problem for a long time now, I often needed to mix Matchers and values and I never managed to do that with Mockito.... until recently ! I put the solution here hoping it will help someone even if this post is quite old.

It is clearly not possible to use Matchers AND values together in Mockito, but what if there was a Matcher accepting to compare a variable ? That would solve the problem... and in fact there is : eq

when(recommendedAccessor.searchRecommendedHolidaysProduct(eq(metas), any(List.class), any(HotelsBoardBasisType.class), any(Config.class)))
            .thenReturn(recommendedResults);

In this example 'metas' is an existing list of values

Try this:

From the libraries tab:

Eclipse -> right click on project name in sidebar -> configure build path -> Libraries

Remove your web app libraries:

click on "Web App Libraries" -> click "remove"

Add them back in:

click "Add Library" -> click to highlight "Web App Libraries" -> click "next" -> confirm your desired project is the selected option -> click "Finish"

Highlighting "Web App Libraries":

Items should have an "ID" field, and Tags should have an "ID" field (Primary Key, Clustered).

Then make an intermediate table of ItemID/TagID and put the "Perfect Index" on there.

If you're on linux then you can grab the guest processes with

ps axuw | grep vmware-vmx

As @Dubas pointed out, you should be able to pick out the errant process by the path name to the VMD

If you have your text in your_text variable, you can use:

your_text[0..29]

strtotime() gives you a number back that represents a time in seconds. To increment it, add the corresponding number of seconds you want to add. 10 hours = 60*60*10 = 36000, so...

$date = date('h:i:s A', strtotime($today)+36000); // $today is today date

Edit: I had assumed you had a string time in $today - if you're just using the current time, even simpler:

$date = date('h:i:s A', time()+36000); // time() returns a time in seconds already

Apparently, _JAVA_OPTIONS works on Linux, too:

$ export _JAVA_OPTIONS="-Xmx1g"
$ java -jar jconsole.jar &
Picked up _JAVA_OPTIONS: -Xmx1g

Something like this:

 $("input[name=test]").is(":checked");

Using the jQuery is() function should work.

If you use anaconda, you can just create a new environment with the specified version. In case you don't want to keep the existing version 3.7, you can just uninstall it and install it from here.

Scanner scanner = new Scanner(new File("tall.txt"));
int [] tall = new int [100];
int i = 0;
while(scanner.hasNextInt()){
   tall[i++] = scanner.nextInt();

            select Task.Run(async delegate
            {
                using (partition)
                    while (partition.MoveNext())
                        await body(partition.Current).ConfigureAwait(false);
            }));
    }
}

And then use like so:

Task.Run(async () =>
{
    var s3 = new AmazonS3Client(Config.Instance.Aws.Credentials, Config.Instance.Aws.RegionEndpoint);
    var buckets = await s3.ListBucketsAsync();

    foreach (var s3Bucket in buckets.Buckets)
    {
        if (s3Bucket.BucketName.StartsWith("mybucket-"))
        {
            log.Information("Bucket => {BucketName}", s3Bucket.BucketName);

            ListObjectsResponse objects;
            try
            {
                objects = await s3.ListObjectsAsync(s3Bucket.BucketName);
            }
            catch
            {
                log.Error("Error getting objects. Bucket => {BucketName}", s3Bucket.BucketName);
                continue;
            }

            // ForEachAsync (4 is how many tasks you want to run in parallel)
            await objects.S3Objects.ForEachAsync(4, async s3Object =>
            {
                try
                {
                    log.Information("Bucket => {BucketName} => {Key}", s3Bucket.BucketName, s3Object.Key);
                    await s3.DeleteObjectAsync(s3Bucket.BucketName, s3Object.Key);
                }
                catch
                {
                    log.Error("Error deleting bucket {BucketName} object {Key}", s3Bucket.BucketName, s3Object.Key);
                }
            });

            try
            {
                await s3.DeleteBucketAsync(s3Bucket.BucketName);
            }
            catch
            {
                log.Error("Error deleting bucket {BucketName}", s3Bucket.BucketName);
            }
        }
    }
}).Wait();

Add -storepass to keytool arguments.

keytool -storepasswd -storepass '' -keystore mykeystore.jks

But also notice that -list command does not always require a password. I could execute follow command in both cases: without password or with valid password

I know this question has been answered already, however, I still would like to add to what a lot has posted here for others having a similar but not specific problem.

This error sometimes also comes as “Android resource linking failed”. It is sometimes vague. The solution sometimes could be quite boring and painful but, this error is absolutely nothing serious.

In this case, the error is not Vague because Android Studio pointed to the problem file.

General Cause The error shows up when Gradle encounters an error (Usually a syntax or typo error) in one or more of your XML files.

Most of the XML files are located in the res folder, however, you might still find some outside the res folder. For example, the AndroidManifest.xml located in “/src/main/AndroidManifest.xml”. Here is an example of a layout file that would give the “Error: failed linking file resources” error.

Solution To solve this problem, all you have to do is go through each of your XML files to figure out where the error might be. This could sometimes be time-consuming but be rest assured that the error will disappear as soon as you find and fix the problem XML.

You might be lucky and Android Studio will point you in the exact direction just like the one asked in the question......

Other times like when you are using an older version of Android Studio, the error would not be this specific.

Here are some Tips to finding the problem XML quickly If you have a lot of XML files and it would be just too difficult to go through them one after the other, you could use the following tips to make the process easier:

Undo: Most times, you are already halfway through a project before you experience this issue. Meaning that it was a recent change to one of your XML files that caused the issue. If that is the case, you can try to undo your recent change to the XML files. To undo, simply use the key combination: Ctrl+Z.

Open every XML file: The second method involves simply opening every single XML file in your project (Without scanning). The reason for this is that sometimes, after opening the problem XML file, Android Studio then detects the error and underlines the exact line.

What worked for me was (adapt "css/style.css" to your css path):

Head HTML:

 <link rel="stylesheet" type="text/css" href="css/style.css" media="screen" />

Body HTML:

 <div class="container">
  <div class="row">
    <div class="mycentered-text">
      <button class="btn btn-default"> Login </button>
    </div>
  </div>
</div>

Css:

.mycentered-text {
    text-align:center
}

There is an app in google play known as MyAppSharer. Open the app, search for the app that you have installed, check apk and select share. The app would take some time and build the apk. You can then close the app. The apk of the file is located in /sdcard/MyAppSharer

This does not require rooting your phone and works only for apps that are currently installed on your phone

The first allocates an object with automatic storage duration, which means it will be destructed automatically upon exit from the scope in which it is defined.

The second allocated an object with dynamic storage duration, which means it will not be destructed until you explicitly use delete to do so.

I created a library to address the need for a page indicator in a ViewPager. My library contains a View called DotIndicator. To use my library, add compile 'com.matthew-tamlin:sliding-intro-screen:3.2.0' to your gradle build file.

The View can be added to your layout by adding the following:

    <com.matthewtamlin.sliding_intro_screen_library.indicators.DotIndicator
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            app:numberOfDots=YOUR_INT_HERE
            app:selectedDotIndex=YOUR_INT_HERE/>

The above code perfectly replicates the functionality of the dots on the Google Launcher homescreen, however if you want to further customise it then the following attributes can be added:

• app:unselectedDotDiameter and app:selectedDotDiameter to set the diameters of the dots
• app:unselectedDotColor and app:selectedDotColor to set the colors of the dots
• app:spacingBetweenDots to change the distance between the dots
• app:dotTransitionDuration to set the time for animating the change from small to big (and back)

Additionally, the view can be created programatically using:

DotIndicator indicator = new DotIndicator(context);

Methods exist to modify the properties, similar to the attributes. To update the indicator to show a different page as selected, just call method indicator.setSelectedItem(int, true) from inside ViewPager.OnPageChangeListener.onPageSelected(int).

Here's an example of it in use:

If you're interested, the library was actually designed to make intro screens like the one shown in the above gif.

Github source available here: https://github.com/MatthewTamlin/SlidingIntroScreen

Build system independent method

make SHELL='sh -x'

is another option. Sample Makefile:

a:
    @echo a

Output:

+ echo a
a

This sets the special SHELL variable for make, and -x tells sh to print the expanded line before executing it.

One advantage over -n is that is actually runs the commands. I have found that for some projects (e.g. Linux kernel) that -n may stop running much earlier than usual probably because of dependency problems.

One downside of this method is that you have to ensure that the shell that will be used is sh, which is the default one used by Make as they are POSIX, but could be changed with the SHELL make variable.

Doing sh -v would be cool as well, but Dash 0.5.7 (Ubuntu 14.04 sh) ignores for -c commands (which seems to be how make uses it) so it doesn't do anything.

make -p will also interest you, which prints the values of set variables.

CMake generated Makefiles always support VERBOSE=1

As in:

mkdir build
cd build
cmake ..
make VERBOSE=1

Dedicated question at: Using CMake with GNU Make: How can I see the exact commands?

in devices which has Android 4.3 and above you should follow these steps:

How to enable Developer Options:

Launch Settings menu.
Find the open the ‘About Device’ menu.
Scroll down to ‘Build Number’.
Next, tap on the ‘build number’ section seven times.
After the seventh tap you will be told that you are now a developer.
Go back to Settings menu and the Developer Options menu will now be displayed.

In order to enable the USB Debugging you will simply need to open Developer Options, scroll down and tick the box that says ‘USB Debugging’. That’s it.

This is because of the proxy settings. I also had the same problem, under which I could not use any of the modules which were fetching data from the internet. There are simple steps to follow:
1. open the control panel
2. open internet options
3. under connection tab open LAN settings
4. go to advance settings and unmark everything, delete every proxy in there. Or u can just unmark the checkbox in proxy server this will also do the same
5. save all the settings by clicking ok.
you are done. try to run the programme again, it must work it worked for me at least

Here's a complete answer with Objective C and Swift:

1) Create an IBAction unwind segue in your destination view controller (where you want to segue to). Anywhere in the implementation file.

// Objective C

    - (IBAction)unwindToContainerVC:(UIStoryboardSegue *)segue {

    }

// Swift

 @IBAction func unwindToContainerVC(segue: UIStoryboardSegue) {

    }

2) On the source view controller (the controller you're segueing from), ^ + drag from "Name of activity" to exit. You should see the unwind segue created in step 1 in the popup. (If you don't see it, review step one). Pick unwindToContainerVC: from the popup, or whatever you named your method to connect your source controller to the unwind IBAction.

3) Select the segue in the source view controller's document outline of the storyboard (it will be listed near the bottom), and give it an identifier.

4) Call the unwind segue using this method from source view controller, substituting your unwind segue name.

// Objective C

[self performSegueWithIdentifier:@"unwindToContainerVC" sender:self];

// Swift

self.performSegueWithIdentifier("unwindToContainerVC", sender: self)

NB. Use the sourceViewController property of the segue parameter on the unwind method to access any exposed properties on the source controller. Also, notice that the framework handles dismissing the source controller. If you'd like to confirm this add a dealloc method to the source controller with a log message that should fire once it has been killed. If dealloc doesn't fire you may have a retain cycle.

Here's a quick and dirty example of how to use an ArrayAdapter if you don't want to bother yourself with extending the mother class:

class MyClass extends Activity {
    private ArrayAdapter<String> mAdapter = null;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        mAdapter = new ArrayAdapter<String>(getApplicationContext(),
            android.R.layout.simple_dropdown_item_1line, android.R.id.text1);

        final ListView list = (ListView) findViewById(R.id.list);
        list.setAdapter(mAdapter);

        //Add Some Items in your list:
        for (int i = 1; i <= 10; i++) {
            mAdapter.add("Item " + i);
        }

        // And if you want selection feedback:
        list.setOnItemClickListener(new OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
                //Do whatever you want with the selected item
                Log.d(TAG, mAdapter.getItem(position) + " has been selected!");
            }
        });
    }
}

In addition to the above I personally recommend

onKeyUp():

Programatically Speaking keydown will fire when the user depresses a key initially but It will repeat while the user keeps the key depressed.*

This remains true for all development platforms.

Google development suggested that if you are intercepting the BACK button in a view you should track the KeyEvent with starttracking on keydown then invoke with keyup.

public boolean onKeyDown(int keyCode, KeyEvent event) {
    if (keyCode == KeyEvent.KEYCODE_BACK
            && event.getRepeatCount() == 0) {
        event.startTracking();
        return true;
    }
    return super.onKeyDown(keyCode, event);
}

public boolean onKeyUp(int keyCode, KeyEvent event) {
    if (keyCode == KeyEvent.KEYCODE_BACK && event.isTracking()
            && !event.isCanceled()) {
        // *** Your Code ***
        return true;
    }
    return super.onKeyUp(keyCode, event);
}

I would usually go with the following code in my plain PHP projects.

if(!defined('ENVIRONMENT')){
    define('ENVIRONMENT', 'DEVELOPMENT');
}

$base_url = null;

if (defined('ENVIRONMENT'))
{
    switch (ENVIRONMENT)
    {
        case 'DEVELOPMENT':
            $base_url = 'http://localhost/product/';
            ini_set('display_errors', 1);
            ini_set('display_startup_errors', 1);
            error_reporting(E_ALL|E_STRICT);
            break;

        case 'PRODUCTION':
            $base_url = 'Production URL'; /* https://google.com */
            error_reporting(0);
            /* Mechanism to log errors */
            break;

        default:
            exit('The application environment is not set correctly.');
    }
}

I'd try doing this with jQuery's .hover() event handler system, it makes it easy to show a div with the tooltip when the mouse is over the text, and hide it once it's gone.

Here's a simple example.

HTML:

?<p id="testText">Some Text</p>
<div id="tooltip">Tooltip Hint Text</div>???????????????????????????????????????????

Basic CSS:

?#?tooltip {
display:none;
border:1px solid #F00;
width:150px;
}?

jQuery:

$("#testText").hover(
   function(e){
       $("#tooltip").show();
   },
   function(e){
       $("#tooltip").hide();
  });??????????

$('div').css({"-webkit-transform":"translate(100px,100px)"});?

My approach is very close to Garret Wilson's (thanks, I voted you up ;)

In addition it provides downward compatibility with Android < 3.

I just recognized that my solution is even closer to the one by Kevin Remo. It's just a wee bit cleaner (as it does not rely on the "expection" antipattern).

public class MyPreferenceActivity extends PreferenceActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        if (Build.VERSION.SDK_INT < Build.VERSION_CODES.HONEYCOMB) {
            onCreatePreferenceActivity();
        } else {
            onCreatePreferenceFragment();
        }
    }

    /**
     * Wraps legacy {@link #onCreate(Bundle)} code for Android < 3 (i.e. API lvl
     * < 11).
     */
    @SuppressWarnings("deprecation")
    private void onCreatePreferenceActivity() {
        addPreferencesFromResource(R.xml.preferences);
    }

    /**
     * Wraps {@link #onCreate(Bundle)} code for Android >= 3 (i.e. API lvl >=
     * 11).
     */
    @TargetApi(Build.VERSION_CODES.HONEYCOMB)
    private void onCreatePreferenceFragment() {
        getFragmentManager().beginTransaction()
                .replace(android.R.id.content, new MyPreferenceFragment ())
                .commit();
    }
}

For a "real" (but more complex) example see NusicPreferencesActivity and NusicPreferencesFragment.

Both foo() and bar() may generate warnings in some IDEs. For example, IntelliJ IDEA will generate a Allocation of zero-length array warning.

An alternative approach is to use Apache Commons Lang 3 ArrayUtils.toArray() function with empty arguments:

public File[] bazz() {
    return ArrayUtils.toArray();
}

This approach is both performance and IDE friendly, yet requires a 3rd party dependency. However, if you already have commons-lang3 in your classpath, you could even use statically-defined empty arrays for primitive types:

public String[] bazz() {
    return ArrayUtils.EMPTY_STRING_ARRAY;
}

I use to work with $http, when a want to get some information from a resource I do the following:

angular.module('services.value', [])

.service('Value', function($http, $q) {

var URL = "http://localhost:8080/myWeb/rest/";

var valid = false;

return {
    isValid: valid,
    getIsValid: function(callback){
        return $http.get(URL + email+'/'+password, {cache: false})
                    .success(function(data){
            if(data === 'true'){ valid = true; }
        }).then(callback);
    }}
    });

And the code in the controller:

angular.module('controllers.value', ['services.value'])

.controller('ValueController', function($scope, Value) {
    $scope.obtainValue = function(){
        Value.getIsValid(function(){$scope.printValue();});
    }

    $scope.printValue = function(){
        console.log("Do it, and value is " Value.isValid);
    }
}

I send to the service what function have to call in the controller

Curl should now work with that URL correctly.

It happens because you call it before DOM has loaded. Firstly, create the element and add atrributes to it, then after DOM has loaded call it. In your case it should look like that:

var canvas = document.createElement('canvas');
canvas.id     = "CursorLayer";
canvas.width  = 1224;
canvas.height = 768;
canvas.style.zIndex   = 8;
canvas.style.position = "absolute";
canvas.style.border   = "1px solid";
window.onload = function() {
    document.getElementById("CursorLayer");
}

What the PHP Notice means and how to reproduce it:

If you send a PHP array into a function that expects a string like: echo or print, then the PHP interpreter will convert your array to the literal string Array, throw this Notice and keep going. For example:

php> print(array(1,2,3))

PHP Notice:  Array to string conversion in 
/usr/local/lib/python2.7/dist-packages/phpsh/phpsh.php(591) :
eval()'d code on line 1
Array

In this case, the function print dumps the literal string: Array to stdout and then logs the Notice to stderr and keeps going.

Another example in a PHP script:

<?php
    $stuff = array(1,2,3);
    print $stuff;  //PHP Notice:  Array to string conversion in yourfile on line 3
?>

Correction 1: use foreach loop to access array elements

http://php.net/foreach

$stuff = array(1,2,3);
foreach ($stuff as $value) {
    echo $value, "\n";
}

Prints:

1
2
3

Or along with array keys

$stuff = array('name' => 'Joe', 'email' => '[email protected]');
foreach ($stuff as $key => $value) {
    echo "$key: $value\n";
}

Prints:

name: Joe
email: [email protected]

Note that array elements could be arrays as well. In this case either use foreach again or access this inner array elements using array syntax, e.g. $row['name']

Correction 2: Joining all the cells in the array together:

In case it's just a plain 1-demensional array, you can simply join all the cells into a string using a delimiter:

<?php
    $stuff = array(1,2,3);
    print implode(", ", $stuff);    //prints 1, 2, 3
    print join(',', $stuff);        //prints 1,2,3

Correction 3: Stringify an array with complex structure:

In case your array has a complex structure but you need to convert it to a string anyway, then use http://php.net/json_encode

$stuff = array('name' => 'Joe', 'email' => '[email protected]');
print json_encode($stuff);

Prints

{"name":"Joe","email":"[email protected]"}

A quick peek into array structure: use the builtin php functions

If you want just to inspect the array contents for the debugging purpose, use one of the following functions. Keep in mind that var_dump is most informative of them and thus usually being preferred for the purpose

• http://php.net/print_r
• http://php.net/var_dump
• http://php.net/var_export

examples

$stuff = array(1,2,3);
print_r($stuff);
$stuff = array(3,4,5);
var_dump($stuff);

Prints:

Array
(
    [0] => 1
    [1] => 2
    [2] => 3
)
array(3) {
  [0]=>
  int(3)
  [1]=>
  int(4)
  [2]=>
  int(5)
}

Here's some JavaScript for copy-paste ease (this is irritate's answer):

function scaleBetween(unscaledNum, minAllowed, maxAllowed, min, max) {
  return (maxAllowed - minAllowed) * (unscaledNum - min) / (max - min) + minAllowed;
}

Applied like so, scaling the range 10-50 to a range between 0-100.

var unscaledNums = [10, 13, 25, 28, 43, 50];

var maxRange = Math.max.apply(Math, unscaledNums);
var minRange = Math.min.apply(Math, unscaledNums);

for (var i = 0; i < unscaledNums.length; i++) {
  var unscaled = unscaledNums[i];
  var scaled = scaleBetween(unscaled, 0, 100, minRange, maxRange);
  console.log(scaled.toFixed(2));
}

0.00, 18.37, 48.98, 55.10, 85.71, 100.00

Edit:

I know I answered this a long time ago, but here's a cleaner function that I use now:

Array.prototype.scaleBetween = function(scaledMin, scaledMax) {
  var max = Math.max.apply(Math, this);
  var min = Math.min.apply(Math, this);
  return this.map(num => (scaledMax-scaledMin)*(num-min)/(max-min)+scaledMin);
}

Applied like so:

[-4, 0, 5, 6, 9].scaleBetween(0, 100);

[0, 30.76923076923077, 69.23076923076923, 76.92307692307692, 100]

just put this method in your forms then it will handle double-click or more clicks in once. once request send it will not allow sending again and again request.

<script type="text/javascript">
    $(document).ready(function(){
            $("form").submit(function() {
                $(this).submit(function() {
                    return false;
                });
                return true;
            }); 
    }); 
</script>

it will help you for sure.

If you are also trying to gzip dynamic pages (like aspx) and it isnt working, its probably because the option is not enabled (you need to install the Dynamic Content Compression module using Windows Features):

In this code the path is stored in the %1 argument (which is written in the registry under quote that are escaped: \"%1\" ). To retrieve it, we need the $arg (inbuilt arg). Don't forget the quote around $FilePath.

# Get the File path:  
$FilePath = $args
Write-Host "FilePath: " $FilePath

# Get the complete file name:
$file_name_complete = [System.IO.Path]::GetFileName("$FilePath")
Write-Host "fileNameFull :" $file_name_complete

# Get File Name Without Extension:
$fileNameOnly = [System.IO.Path]::GetFileNameWithoutExtension("$FilePath")
Write-Host "fileNameOnly :" $fileNameOnly

# Get the Extension:
$fileExtensionOnly = [System.IO.Path]::GetExtension("$FilePath")
Write-Host "fileExtensionOnly :" $fileExtensionOnly

As per your question vertical listing have a scrollbar effect.

No, there isn't. The designers of Java are on record as saying they didn't like unsigned ints. Use a BigInteger instead. See this question for details.

I have finally gotten what I needed.

I needed to scroll to the top, but wanted some transitions not to

You can control this on a route-by-route level.
I'm combining the above solution by @wkonkel and adding a simple noScroll: true parameter to some route declarations. Then I'm catching that in the transition.

All in all: This floats to the top of the page on new transitions, it doesn't float to the top on Forward / Back transitions, and it allows you to override this behavior if necessary.

The code: (previous solution plus an extra noScroll option)

  // hack to scroll to top when navigating to new URLS but not back/forward
  let wrap = function(method) {
    let orig = $window.window.history[method];
    $window.window.history[method] = function() {
      let retval = orig.apply(this, Array.prototype.slice.call(arguments));
      if($state.current && $state.current.noScroll) {
        return retval;
      }
      $anchorScroll();
      return retval;
    };
  };
  wrap('pushState');
  wrap('replaceState');

Put that in your app.run block and inject $state... myApp.run(function($state){...})

Then, If you don't want to scroll to the top of the page, create a route like this:

.state('someState', {
  parent: 'someParent',
  url: 'someUrl',
  noScroll : true // Notice this parameter here!
})

Here are some ways to edit the text and the size of the box:

rows="insertNumber"
cols="insertNumber"
style="font-size:12pt"

Example:

<textarea rows="5" cols="30" style="font-size: 12pt" id="myText">Enter 
Text Here</textarea>
