cursor:url('http://www.javascriptkit.com/dhtmltutors/cursor-hand.gif'), auto

NOTE 1: In some cases you should consider setting the offset (anchor):

cursor:url(http://www.javascriptkit.com/dhtmltutors/cursor-hand.gif) 10 3, auto;

in this exmple, we set offsetx to 10 and offsety to 3 (from top left), so the pointer finger will be anchor. fiddle: http://jsfiddle.net/5kxt1j98/ (you can see the difference by moving cursor to top left of container)

NOTE 2: THE MAX CURSOR SIZE IS 128*128, recommended one is below 32*32.

It's not really possible. You could, but if you're going to it would be useless without appropriate plugins. You'd be better using some other form. PDF's are used to have a consolidated output to printers and the screen, so animations won't work without other resources, and then it's not really a PDF.

Very easy code. You keep appending the path each time you discover a node.

graph = {
         'A': set(['B', 'C']),
         'B': set(['A', 'D', 'E']),
         'C': set(['A', 'F']),
         'D': set(['B']),
         'E': set(['B', 'F']),
         'F': set(['C', 'E'])
         }
def retunShortestPath(graph, start, end):

    queue = [(start,[start])]
    visited = set()

    while queue:
        vertex, path = queue.pop(0)
        visited.add(vertex)
        for node in graph[vertex]:
            if node == end:
                return path + [end]
            else:
                if node not in visited:
                    visited.add(node)
                    queue.append((node, path + [node]))

So.. I was also looking into this matter and saw that most of the answers here are asking to fade the container element, not the actual background-image. Then a hack crossed my mind. We can give multiple background right? what if we overlay other color and make it transparent, like code below-

 background: url("//unsplash.it/500/400") rgb(255, 255, 255, 0.5) no-repeat center;

This code actually works stand alone. Try it. We gave a bg image and asked other white color with transparency on top of the image and Voila. TIP- we can give different colors and transparencies to get different filter kind of effect.

In my experience, I always just use an external program to generate the graph (mathematica, gnuplot, matlab, etc.) and export the graph as a pdf or eps file. Then I include it into the document with includegraphics.

According to this page, it's ∞.

Long time since I've done Assembly programming, but this link might be useful...

The processor has a collection of registers which are used to store data. Some of these are direct values while others are pointing to an area within RAM. Registers do tend to be used for certain specific actions and every operand in assembly will require a certain amount of data in specific registers.

The stack pointer is mostly used when you're calling other procedures. With modern compilers, a bunch of data will be dumped first on the stack, followed by the return address so the system will know where to return once it's told to return. The stack pointer will point at the next location where new data can be pushed to the stack, where it will stay until it's popped back again.

Base registers or segment registers just point to the address space of a large amount of data. Combined with a second regiser, the Base pointer will divide the memory in huge blocks while the second register will point at an item within this block. Base pointers therefor point to the base of blocks of data.

Do keep in mind that Assembly is very CPU specific. The page I've linked to provides information about different types of CPU's.

This KineticModel is an implementation of the cited approach in Java.

Without Homebrew

1. Use the installer from git's website.
2. Update your ~/.bash_profile file. Notice this command differs from kmikael's answer by what it puts in the file:
   • Other command: export PATH=/usr/local/git/bin:/usr/local/sbin/:[and so on]
   • Below command: export PATH="/usr/local/git/bin:/usr/local/sbin:$PATH"
   • Use whichever one you prefer.

echo 'export PATH="/usr/local/git/bin:/usr/local/sbin:$PATH"' >> ~/.bash_profile

3. If you're using Xcode, you'll need to add some symbolic links.
   • Example: ln -s /opt/local/bin/git /usr/bin/git
4. Restart terminal.
   • which git should say the directory in the README.txt file from the dmg.
   • git --version should say the updated version.
   • echo $PATH should start with /usr/local/git/bin:/usr/local/sbin:

Look at java.lang.BigDecimal, may solve your problem.

http://docs.oracle.com/javase/7/docs/api/java/math/BigDecimal.html

In Python mutable objects are passed as reference, so you can pass a reference of the outer class to the inner class.

class OuterClass:
    def __init__(self):
        self.outer_var = 1
        self.inner_class = OuterClass.InnerClass(self)
        print('Inner variable in OuterClass = %d' % self.inner_class.inner_var)

    class InnerClass:
        def __init__(self, outer_class):
            self.outer_class = outer_class
            self.inner_var = 2
            print('Outer variable in InnerClass = %d' % self.outer_class.outer_var)

Info from http://w3schools.com/sql/sql_null_values.asp:

1) NULL values represent missing unknown data.

2) By default, a table column can hold NULL values.

3) NULL values are treated differently from other values

4) It is not possible to compare NULL and 0; they are not equivalent.

5) It is not possible to test for NULL values with comparison operators, such as =, <, or <>.

6) We will have to use the IS NULL and IS NOT NULL operators instead

So in case of your problem:

SELECT pid FROM planets WHERE userid IS NULL

It looks like you may have to do a bit of manual installation for PyQt4.

http://pyqt.sourceforge.net/Docs/PyQt4/installation.html

This might help a bit more, it's a bit more in a tutorial/set-by-step format:

http://movingthelamppost.com/blog/html/2013/07/12/installing_pyqt____because_it_s_too_good_for_pip_or_easy_install_.html

do it with the following code:

DocumentBuilderFactory builderFactory = DocumentBuilderFactory.newInstance();

    try {
        DocumentBuilder builder = builderFactory.newDocumentBuilder();
        Document doc = builder.parse("/home/codefelix/IdeaProjects/Gradle/src/main/resources/static/Employees.xml");
        NodeList namelist = (NodeList) doc.getElementById("1");

        for (int i = 0; i < namelist.getLength(); i++) {
            Node p = namelist.item(i);

            if (p.getNodeType() == Node.ELEMENT_NODE) {
                Element person = (Element) p;
                NodeList id = (NodeList) person.getElementsByTagName("Employee");
                NodeList nodeList = person.getChildNodes();
                List<EmployeeDto> employeeDtoList=new ArrayList();

                for (int j = 0; j < nodeList.getLength(); j++) {
                    Node n = nodeList.item(j);

                    if (n.getNodeType() == Node.ELEMENT_NODE) {
                        Element naame = (Element) n;
                        System.out.println("Employee" + id + ":" + naame.getTagName() + "=" +naame.getTextContent());
                    }
                }
            }
        }
    } catch (ParserConfigurationException e) {
        e.printStackTrace();
    } catch (SAXException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }
}

}

Another approach when you have many updates would be to use COALESCE:

UPDATE [DATABASE].[dbo].[TABLE_NAME]
SET    
    [ABC]  = COALESCE(@ABC, [ABC]),
    [ABCD] = COALESCE(@ABCD, [ABCD])

One way to do this is to pull your field into the rows section of the pivot table from the Filter section. Then group the values that you want to keep into a group, using the group option on the menu. After that is completed, drag your field back into the Filters section. The grouping will remain and you can check or uncheck one box to remove lots of values.

Anaconda comes with the conda package manager which is designed to handle these kinds of upgrades. Start by updating conda itself to get the most recent package lists:

conda update conda

And then install the version of scikit-learn you want

conda install scikit-learn=0.17

All necessary dependencies will be upgraded as well. If you have trouble with conda on Windows, there are some relevant FAQ here: http://docs.continuum.io/anaconda/faq

I recently discovered an interesting trick that allows to "Split String With String As Delimiter", so I couldn't resist the temptation to post it here as a new answer. Note that "obviously the question wasn't accurate. Firstly, both string1 and string2 can contain spaces. Secondly, both string1 and string2 can contain ampersands ('&')". This method correctly works with the new specifications (posted as a comment below Stephan's answer).

@echo off
setlocal

set "str=string1&with spaces by string2&with spaces.txt"

set "string1=%str: by =" & set "string2=%"
set "string2=%string2:.txt=%"

echo "%string1%"
echo "%string2%"

For further details on the split method, see this post.

This can achieve using two SQL functions- SUBSTRING and CHARINDEX

You can read strings to a variable as shown in the above answers, or can add it to a SELECT statement as below:

SELECT SUBSTRING('Net Operating Loss - 2007' ,0, CHARINDEX('-','Net Operating Loss - 2007'))

If you're using the MVC preview 4, you could be experiencing this because you're using the HandleErrorAttribute. The behavior changed in 5 so that it doesn't handle exceptions if you turn off custom errors.

Run the following commands in the terminal:

rm -Rf /Applications/Android\ Studio.app  
rm -Rf ~/Library/Preferences/AndroidStudio*  
rm -Rf ~/Library/Preferences/com.google.android.*  
rm -Rf ~/Library/Preferences/com.android.*  
rm -Rf ~/Library/Application\ Support/AndroidStudio*

rm -Rf ~/.AndroidStudio*  
rm -Rf ~/.gradle  
rm -Rf ~/.android  
rm -Rf ~/Library/Android*  
rm -Rf /usr/local/var/lib/android-sdk/  

To delete all projects:

rm -Rf ~/AndroidStudioProjects  

Based on quick inspection of google web, this would be CSS path to links in page list

ol[id="rso"] h3[class="r"] a

So you should do something like

String path = "ol[id='rso'] h3[class='r'] a";
driver.findElements(By.cssSelector(path)).get(2).click();

However you could also use xpath which is not really recommended as a best practice and also JQuery locators but I am not sure if you can use them aynywhere else except inArquillian Graphene

The memory must be configured in several places.
Set memory_limit to 512M:

sudo vi /etc/php5/cgi/php.ini
sudo vi /etc/php5/cli/php.ini
sudo vi /etc/php5/apache2/php.ini Or /etc/php5/fpm/php.ini

Restart service:

sudo service service php5-fpm restart
sudo service service nginx restart

or

sudo service apache2 restart

Finally it should solve the problem of the memory_limit

By simply subtracting by char '0'(zero) a char (of digit '0' to '9') can be converted into int(0 to 9), e.g., '5'-'0' gives int 5.

String str = "123";

int a=str.charAt(1)-'0';

One more idea for anyone else getting this...

I had some gzipped svg, but it had a php error in the output, which caused this error message. (Because there was text in the middle of gzip binary.) Fixing the php error solved it.

Here is a sample script that I recently used in a Gateway POST transaction that receives a GET response. Are you using this in a custom C# form? Whatever your purpose, just replace the String fields (username, password, etc.) with the parameters from your form.

private String readHtmlPage(string url)
   {

    //setup some variables

    String username  = "demo";
    String password  = "password";
    String firstname = "John";
    String lastname  = "Smith";

    //setup some variables end

      String result = "";
      String strPost = "username="+username+"&password="+password+"&firstname="+firstname+"&lastname="+lastname;
      StreamWriter myWriter = null;

      HttpWebRequest objRequest = (HttpWebRequest)WebRequest.Create(url);
      objRequest.Method = "POST";
      objRequest.ContentLength = strPost.Length;
      objRequest.ContentType = "application/x-www-form-urlencoded";

      try
      {
         myWriter = new StreamWriter(objRequest.GetRequestStream());
         myWriter.Write(strPost);
      }
      catch (Exception e) 
      {
         return e.Message;
      }
      finally {
         myWriter.Close();
      }

      HttpWebResponse objResponse = (HttpWebResponse)objRequest.GetResponse();
      using (StreamReader sr = 
         new StreamReader(objResponse.GetResponseStream()) )
      {
         result = sr.ReadToEnd();

         // Close and clean up the StreamReader
         sr.Close();
      }
      return result;
   } 

to get all the data that contains duplication i used this:

SELECT * FROM TableName INNER JOIN(
  SELECT DupliactedData FROM TableName GROUP BY DupliactedData HAVING COUNT(DupliactedData) > 1 order by DupliactedData)
  temp ON TableName.DupliactedData = temp.DupliactedData;

TableName = the table you are working with.

DupliactedData = the duplicated data you are looking for.

// sample code for addition using JOptionPane

import javax.swing.JOptionPane;

public class Addition {

    public static void main(String[] args) {

        String firstNumber = JOptionPane.showInputDialog("Input <First Integer>");

        String secondNumber = JOptionPane.showInputDialog("Input <Second Integer>");

        int num1 = Integer.parseInt(firstNumber);
        int num2 = Integer.parseInt(secondNumber);
        int sum = num1 + num2;
        JOptionPane.showMessageDialog(null, "Sum is" + sum, "Sum of two Integers", JOptionPane.PLAIN_MESSAGE);
    }
}

You can use a pseudo-element to position as the background of the content with the same image as the background, but blurred with the new CSS3 filter.

You can see it in action here: http://codepen.io/jiserra/pen/JzKpx

I made that for customizing a select, but I added the blur background effect.

update We have since just installed our own Nexus server, much easier and cleaner.

At our company we had some jars that we some jars that were common but were not hosted in any maven repositories, nor did we want to have them in local storage. We created a very simple mvn (public) repo on Github (but you can host it on any server or locally):
note that this is only ideal for managing a few rarely chaning jar files

1. Create repo on GitHub:
   https://github.com/<user_name>/mvn-repo/

2. Add Repository in pom.xml
   (Make note that the full path raw file will be a bit different than the repo name)
   

   <repository>
       <id>project-common</id>
       <name>Project Common</name>
       <url>https://github.com/<user_name>/mvn-repo/raw/master/</url>
   </repository>
   

3. Add dependency to host (Github or private server)
   a. All you need to know is that files are stored in the pattern mentioned by @glitch
   /groupId/artifactId/version/artifactId-version.jar
   b. On your host create the folders to match this pattern.
   i.e if you have a jar file named service-sdk-0.0.1.jar, create the folder service-sdk/service-sdk/0.0.1/ and place the jar file service-sdk-0.0.1.jar into it.
   c. Test it by trying to download the jar from a browser (in our case: https://github.com/<user_name>/mvn-repo/raw/master/service-sdk/service-sdk/0.0.1/service-sdk-0.0.1.jar
   

4. Add dependency to your pom.xml file:
   

   <dependency>
       <groupId>service-sdk</groupId>
       <artifactId>service-sdk</artifactId>
       <version>0.0.1</version>
   </dependency>
   

5. Enjoy

Solution for a fresh install of Tomcat 7 on Ubuntu 12.04.

restart Tomcat -

service tomcat7 restart

urls to access managers -

1. tomcat test page - http://localhost:8080/
2. manager webapp - http://localhost:8080/manager/html
3. host-manager webapp - http://localhost:8080/host-manager/html

just wanted to put the latest info out there.

Here's how you would create such a link:

<a href="javascript:if(confirm('Close window?'))window.close()">close</a>

Just incase Someone needs an easier way:

The following code gives a view of the whole activity:

View v1 = getWindow().getDecorView().getRootView();

To get a certian view in the activity,for example an imageView inside the activity, simply add the id of that view you want to get:

View v1 = getWindow().getDecorView().getRootView().findViewById(R.id.imageView1);

Hope this helps somebody

One more thing that can cause this is when you map a network drive or connect a VHD after GitHub Desktop has already been started. The reason for this is that GitHub Desktop uses ssh-agent from the portable GIT install to establish connections, and never closes it... even if you uninstall the application. The process starts with no knowledge of the new drive and never refreshes itself, and when it is used to run the GIT commands to work on your repo it fails because it doesn't understand the paths.

The solution in this instance is to close GitHub Desktop and use Task Manager to terminate the running ssh-agent before starting it again. This will start a new instance of ssh-agent when needed which will pick up the new drive mappings, etc.

Note: this answer was motivated by this comment. The purpose of UsedRange is different from what is mentioned in the answer above.

As to the correct way of finding the last used cell, one has first to decide what is considered used, and then select a suitable method. I conceive at least three meanings:

1. Used = non-blank, i.e., having data.

2. Used = "... in use, meaning the section that contains data or formatting." As per official documentation, this is the criterion used by Excel at the time of saving. See also this official documentation. If one is not aware of this, the criterion may produce unexpected results, but it may also be intentionally exploited (less often, surely), e.g., to highlight or print specific regions, which may eventually have no data. And, of course, it is desirable as a criterion for the range to use when saving a workbook, lest losing part of one's work.

3. Used = "... in use, meaning the section that contains data or formatting" or conditional formatting. Same as 2., but also including cells that are the target for any Conditional Formatting rule.

How to find the last used cell depends on what you want (your criterion).

For criterion 1, I suggest reading this answer. Note that UsedRange is cited as unreliable. I think that is misleading (i.e., "unfair" to UsedRange), as UsedRange is simply not meant to report the last cell containing data. So it should not be used in this case, as indicated in that answer. See also this comment.

For criterion 2, UsedRange is the most reliable option, as compared to other options also designed for this use. It even makes it unnecessary to save a workbook to make sure that the last cell is updated. Ctrl+End will go to a wrong cell prior to saving (“The last cell is not reset until you save the worksheet”, from http://msdn.microsoft.com/en-us/library/aa139976%28v=office.10%29.aspx. It is an old reference, but in this respect valid).

For criterion 3, I do not know any built-in method. Criterion 2 does not account for Conditional Formatting. One may have formatted cells, based on formulas, which are not detected by UsedRange or Ctrl+End. In the figure, the last cell is B3, since formatting was applied explicitly to it. Cells B6:D7 have a format derived from a Conditional Formatting rule, and this is not detected even by UsedRange. Accounting for this would require some VBA programming.

As to your specific question: What's the reason behind this?

Your code uses the first cell in your range E4:E48 as a trampoline, for jumping down with End(xlDown).

The "erroneous" output will obtain if there are no non-blank cells in your range other than perhaps the first. Then, you are leaping in the dark, i.e., down the worksheet (you should note the difference between blank and empty string!).

Note that:

1. If your range contains non-contiguous non-blank cells, then it will also give a wrong result.

2. If there is only one non-blank cell, but it is not the first one, your code will still give you the correct result.

you can use the below method to extract all numbers from a string.

def extract_numbers_from_string(string):
    number = ''
    for i in string:
        try:
            number += str(int(i))
        except:
            pass
    return number

(OR) you could use i.isdigit() or i.isnumeric(in Python 3.6.5 or above)

def extract_numbers_from_string(string):
    number = ''
    for i in string:
        if i.isnumeric():
            number += str(int(i))
    return number


a = '343fdfd3'
print (extract_numbers_from_string(a))
# 3433

It is pretty easy. If you are using DB generated Ids (like IDENTITY in MS SQL) you just need to add entity to ObjectSet and SaveChanges on related ObjectContext. Id will be automatically filled for you:

using (var context = new MyContext())
{
  context.MyEntities.Add(myNewObject);
  context.SaveChanges();

  int id = myNewObject.Id; // Yes it's here
}

Entity framework by default follows each INSERT with SELECT SCOPE_IDENTITY() when auto-generated Ids are used.

The python error says that wordInput is not an iterable -> it is of NoneType.

If you print wordInput before the offending line, you will see that wordInput is None.

Since wordInput is None, that means that the argument passed to the function is also None. In this case word. You assign the result of pickEasy to word.

The problem is that your pickEasy function does not return anything. In Python, a method that didn't return anything returns a NoneType.

I think you wanted to return a word, so this will suffice:

def pickEasy():
    word = random.choice(easyWords)
    word = str(word)
    for i in range(1, len(word) + 1):
        wordCount.append("_")
    return word

In my case I use finishAffinity() function in last activity like:

finishAffinity()
startHomeActivity()

Hope it'll be useful.

It works for me:

if (isset($_POST['MyTextAreaName'])){
    $array=explode( "\r\n", $_POST['MyTextAreaName'] );

now, my $array will have all the lines I need

    for ($i = 0; $i <= count($array); $i++) 
    {
        echo (trim($array[$i]) . "<br/>");
    }

(make sure to close the if block with another curly brace)

}

Go via POSIXct and you want to set a TZ there -- here you see my (Chicago) default:

R> val <- 1352068320
R> as.POSIXct(val, origin="1970-01-01")
[1] "2012-11-04 22:32:00 CST"
R> as.Date(as.POSIXct(val, origin="1970-01-01"))
[1] "2012-11-05" 
R> 

Edit: A few years later, we can now use the anytime package:

R> library(anytime)
R> anytime(1352068320)
[1] "2012-11-04 16:32:00 CST"
R> anydate(1352068320)
[1] "2012-11-04"
R> 

Note how all this works without any format or origin arguments.

If you miss, Microsoft.CSharp.dll this error can occur. Check you project references.

For what is worth, I took advantage that I was already using bootstrap (4.3), because I needed to add margin, box-shadow and border-radius to my row, something I can't do with tables.

<div id="loop" class="table-responsive px-4">
<section>
    <div id="thead" class="row m-0">
        <div class="col"></div>
        <div class="col"></div>
        <div class="col"></div>
    </div>
    <div id="tbody" class="row m-0">
        <div class="col"></div>
        <div class="col"></div>
        <div class="col"></div>
    </div>
</section>
</div>

On css I added a few lines to mantain the table behavior of bootstrap

@media (max-width: 800px){
    #loop{
        section{
            min-width: 700px;
        }
    }
}

The binary serializer included with .net should be faster that the XmlSerializer. Or another serializer for protobuf, json, ...

But for some of them you need to add Attributes, or some other way to add metadata. For example ProtoBuf uses numeric property IDs internally, and the mapping needs to be somehow conserved by a different mechanism. Versioning isn't trivial with any serializer.

What size this image should be depends on where it is to be used.

It is up to applications, eg WhatsApp, Facebook Messenger, Reddit, etc etc to decide what to do with the image. Some use it as a square image, some as a 1:19.1 rectangle, and some use different sizes when the display environment is of different sizes even for the same application. There are no rules, and there is no way to control what applications do with the image.

So you should test out the image on your intended target application(s) and find a compromise. That applications tend to cache the image makes it a pain on the trial and error approach.

There is a little "hack" on CSS that also allows you to disable scrolling:

.lock-screen {
    height: 100%;
    overflow: hidden;
    width: 100%;
    position: fixed;
}

Adding that class to the body will prevent scrolling.

In SQLServer Management Studio:

Tools -> Options -> Designers -> Table and Database Designers

• Unselect 'Prevent saving changes that require table re-creation'.

Then:

• right click the table you want to re-order the columns for.
• click 'Design'.
• Drag the columns to the order you want.
• finally, click save.

SQLServer Management studio will drop the table and recreate it using the data.

fopen() is a C library function and so you won't see any syscall instructions in your code, just a regular function call. At some point, it does call open(2), but it does that via a trampoline. There is simply a jump to the VDSO page, which is provided by the kernel to every process. The VDSO then provides code to make the system call. On modern processors, the SYSCALL or SYSENTER instructions will be used, but you can also use INT 80h on x86 processors.

While working with selected cells as shown by @tbur can be useful, it's also not the only option available.

You can use Range() like so:

If Worksheets("Sheet1").Range("A1").MergeCells Then
  Do something
Else
  Do something else
End If

Or:

If Worksheets("Sheet1").Range("A1:C1").MergeCells Then
  Do something
Else
  Do something else
End If

Alternately, you can use Cells():

If Worksheets("Sheet1").Cells(1, 1).MergeCells Then
  Do something
Else
  Do something else
End If

The command [Environment]::SetEnvironmentVariable("Path", "$env:Path;C:\Python27", "User") is not a Python command. Instead, this is an operating system command to the set the PATH variable.

You are getting this error as you are inside the Python interpreter which was triggered by the command python you have entered in the terminal (Windows PowerShell).

Please note the >>> at the left side of the line. It states that you are on inside Python interpreter.

Please enter quit() to exit the Python interpreter and then type the command. It should work!

This also works fine, testing by type against undefined.

if (currentData[index] === undefined){return}

Test:

const fruits = ["Banana", "Orange", "Apple", "Mango"];_x000D_
_x000D_
if (fruits["Raspberry"] === undefined){_x000D_
  console.log("No Raspberry entry in fruits!")_x000D_

I will refer you to my blog post - A lesson in address storage, I go into some of the techniques and algorithms used in the process of address validation. My key thought is "Don't be lazy with address storage, it will cause you nothing but headaches in the future!"

Also, there is another StackOverflow question that asks this question. Entitled How should international geographic addresses be stored in a relational database.

I also saw this change on my Mac when I went from running pip to sudo pip. Adding -H to sudo causes the message to go away for me. E.g.

sudo -H pip install foo

man sudo tells me that -H causes sudo to set $HOME to the target users (root in this case).

So it appears pip is looking into $HOME/Library/Log and sudo by default isn't setting $HOME to /root/. Not surprisingly ~/Library/Log is owned by you as a user rather than root.

I suspect this is some recent change in pip. I'll run it with sudo -H for now to work around.

Most answers suggest to just add ServerName localhost to /etc/apache2/apache2.conf.

But quoting Apache documentation :

The presence of this error message also indicates that Apache httpd was unable to obtain a fully-qualified hostname by doing a reverse lookup on your server's IP address. While the above instructions will get rid of the warning in any case, it is also a good idea to fix your name resolution so that this reverse mapping works.

Therefore adding such a line to /etc/hosts is probably a more robust solution :

192.0.2.0  foobar.example.com  foobar

where 192.0.2.0 is the static IP address of the server named foobar within the example.com domain.

One can check the FQDN e.g. with

hostname -A

(shortcut for hostname --all-fqdn).

I encountered a similar problem. The solution is surprisingly simple.

The error message looks like this:

07-05 ...... Invalid key hash. The key hash sL1***************VY= does not match any stored key hashes. Configure your app key hashes at http://developers.facebook.com/apps/150*******778
07-05 ......     at com.facebook.login.LoginManager.onActivityResult(LoginManager.java:191)

Simply log into https://developers.facebook.com , select the "Settings" tab, and add the key hash "sL1***************VY=" to the list of saved Key hashes in the Android panel.

OP stated he didn't want to modify the code for the buttons. This is the least-intrusive answer I could come up with using the other answers as a guide. It doesn't require additional hidden fields, allows you to leave the button code intact (sometimes you don't have access to what generates it), and gives you the info you were looking for from anywhere in your code...which button was used to submit the form. I haven't evaluated what happens if the user uses the Enter key to submit the form, rather than clicking.

<script language="javascript" type="text/javascript">

    var initiator = '';
    $(document).ready(function() {
        $(":submit").click(function() { initiator = this.name });
    });

</script>

Then you have access to the 'initiator' variable anywhere that might need to do the checking. Hope this helps.

If you only want to read the first 999,999 (non-header) rows:

read_csv(..., nrows=999999)

If you only want to read rows 1,000,000 ... 1,999,999

read_csv(..., skiprows=1000000, nrows=999999)

nrows : int, default None Number of rows of file to read. Useful for reading pieces of large files*

skiprows : list-like or integer Row numbers to skip (0-indexed) or number of rows to skip (int) at the start of the file

and for large files, you'll probably also want to use chunksize:

chunksize : int, default None Return TextFileReader object for iteration

For future Googlers i've a different approach to check if it's last element. It's similar to last lines in OP question.

This directly compares elements rather than just checking index numbers.

$yourset.each(function() {
    var $this = $(this);
    if($this[0] === $yourset.last()[0]) {
        //$this is the last one
    }
});

Try this:

true
select cast(salesDate as date) [date] from sales where salesDate = '2010/11/11'
false
select cast(salesDate as date) [date] from sales where salesDate = '11/11/2010'

It's very simple really. Use percentage for width and left properties. For example:

logo : {
  position: 'absolute',
  top : 50,
  left: '30%',
  zIndex: 1,
  width: '40%',
  height: 150,
}

Whatever width is, left equals (100% - width)/2

Although there are a bunch of correct answers above, it should be noted that the String object in JavaScript has a native .trim() method as of ECMAScript 5. Thus ideally any attempt to prototype the trim method should really check to see if it already exists first.

if(!String.prototype.trim){  
  String.prototype.trim = function(){  
    return this.replace(/^\s+|\s+$/g,'');  
  };  
}

Added natively in: JavaScript 1.8.1 / ECMAScript 5

1. Open your ~./bashrc
2. Find the following code (maybe something similar) that launches your conda:

    # >>> conda init >>>
    # !! Contents within this block are managed by 'conda init' !!
    __conda_setup="$(CONDA_REPORT_ERRORS=false '/anaconda3/bin/conda' shell.bash hook 2> /dev/null)" if [ $? -eq 0 ]; then
        \eval "$__conda_setup" else

3. source ~/.zshrc
4. Things should work.

The usual way is to use zip():

for x, y in zip(a, b):
    # x is from a, y is from b

This will stop when the shorter of the two iterables a and b is exhausted. Also worth noting: itertools.izip() (Python 2 only) and itertools.izip_longest() (itertools.zip_longest() in Python 3).

Try:

start  "" "C:\Program Files (x86)\Microsoft Office\Office12\WINWORD.EXE" --new-window/min

I had the same problem, but I was trying to open chrome.exe maximized. If I put the /min anywhere else in the command line, like before or after the empty title, it was ignored.

This will help to find the spaces in the beginning, middle and ending:

var regexp = /\s/g

I like solutions that are "computer science elegant." My solution here hits the [inserted] and [deleted] pseudotables once each to get their statuses and puts the result in a bit mapped variable. Then each possible combination of INSERT, UPDATE and DELETE can readily be tested throughout the trigger with efficient binary evaluations (except for the unlikely INSERT or DELETE combination).

It does make the assumption that it does not matter what the DML statement was if no rows were modified (which should satisfy the vast majority of cases). So while it is not as complete as Roman Pekar's solution, it is more efficient.

With this approach, we have the possibility of one "FOR INSERT, UPDATE, DELETE" trigger per table, giving us A) complete control over action order and b) one code implementation per multi-action-applicable action. (Obviously, every implementation model has its pros and cons; you will need to evaluate your systems individually for what really works best.)

Note that the "exists (select * from «inserted/deleted»)" statements are very efficient since there is no disk access (https://social.msdn.microsoft.com/Forums/en-US/01744422-23fe-42f6-9ab0-a255cdf2904a).

Only a teacher would ask you to do something silly like this. You could provide an expected answer. Or a unique solution, while the rest of the class will be (yawn) the same...

from operator import lt, gt
def ultimate (l,op,c=1,u=0):
    try:
        if op(l[c],l[u]): 
            u = c
        c += 1
        return ultimate(l,op,c,u)
    except IndexError:
        return l[u]
def minimum (l):
    return ultimate(l,lt)
def maximum (l):
    return ultimate(l,gt)

The solution is simple. Use this to set yourself apart from obvious choices.

You need to export the User.name field so that the json package can see it. Rename the name field to Name.

package main

import (
    "fmt"
    "encoding/json"
)

type User struct {
    Name string
}

func main() {
    user := &User{Name: "Frank"}
    b, err := json.Marshal(user)
    if err != nil {
        fmt.Println(err)
        return
    }
    fmt.Println(string(b))
}

Output:

{"Name":"Frank"}

The class which implements KeyListener interface becomes our custom key event listener. This listener can not directly listen the key events. It can only listen the key events through intermediate objects such as JFrame. So

1. Make one Key listener class as

   class MyListener implements KeyListener{
   
      // override all the methods of KeyListener interface.
   }
   

2. Now our class MyKeyListener is ready to listen the key events. But it can not directly do so.

3. Create any object like JFrame object through which MyListener can listen the key events. for that you need to add MyListener object to the JFrame object.

   JFrame f=new JFrame();
   f.addKeyListener(new MyKeyListener);
   

It also changes what pydoc will show:

a = "A"
b = "B"
c = "C"

module2.py

__all__ = ['a', 'b']

a = "A"
b = "B"
c = "C"

$ pydoc module1

Help on module module1:

I declare __all__ in all my modules, as well as underscore internal details, these really help when using things you've never used before in live interpreter sessions.

After many struggles and to achive a general, flexible and more readable solution, in my case I ended up saving the ORs results into ENV variables and doing the ANDs of those variables.

# RESULT_ONE = A OR B
RewriteRule ^ - [E=RESULT_ONE:False]
RewriteCond ...A... [OR]
RewriteCond ...B...
RewriteRule ^ - [E=RESULT_ONE:True]

# RESULT_TWO = C OR D
RewriteRule ^ - [E=RESULT_TWO:False]
RewriteCond ...C... [OR]
RewriteCond ...D...
RewriteRule ^ - [E=RESULT_TWO:True]

# if ( RESULT_ONE AND RESULT_TWO ) then ( RewriteRule ...something... )
RewriteCond %{ENV:RESULT_ONE} =True
RewriteCond %{ENV:RESULT_TWO} =True
RewriteRule ...something...

Requirements:

You can read from file to map, where the key is the date and skip if the the whole row if the date is already in map

        Map<String, List<String>> map = new HashMap<String, List<String>>();

        int i = 0;
        String lastData = null;
        while (s.hasNext()) {
            String str = s.next();
            if (i % 13 == 0) {
                if (map.containsKey(str)) {
                    //skip the whole row
                    lastData = null;
                } else {
                    lastData = str;
                    map.put(lastData, new ArrayList<String>());
                }
            } else if (lastData != null) {
                map.get(lastData).add(str);
            }


            i++;
        }

A user agent style sheet is a ”default style sheet” provided by the browser (e.g., Chrome, Firefox, Edge, etc.) in order to present the page in a way that satisfies ”general presentation expectations.” For example, a default style sheet would provide base styles for things like font size, borders, and spacing between elements. It is common to employ a reset style sheet to deal with inconsistencies amongst browsers.

From the specification...

A user agent's default style sheet should present the elements of the document language in ways that satisfy general presentation expectations for the document language. ~ The Cascade.

For more information about user agents in general, see user agent.

What you are currently doing is checking whether neither the start_date nor the end_date fall within the range of the dates given.

I guess what you are really looking for is a record which does not fit in the date range given. If so, use the query below.

SELECT * 
    FROM `test_table` 
    WHERE  CAST('2009-12-15' AS DATE) > start_date  AND  CAST('2010-01-02' AS DATE) < end_date

I had a similar issue but I was unable to use the UserAgent class inside the fake_useragent module. I was running the code inside a docker container

import requests
import ujson
import random

response = requests.get('https://fake-useragent.herokuapp.com/browsers/0.1.11')
agents_dictionary = ujson.loads(response.text)
random_browser_number = str(random.randint(0, len(agents_dictionary['randomize'])))
random_browser = agents_dictionary['randomize'][random_browser_number]
user_agents_list = agents_dictionary['browsers'][random_browser]
user_agent = user_agents_list[random.randint(0, len(user_agents_list)-1)]

I targeted the endpoint used in the module. This solution still gave me a random user agent however there is the possibility that the data structure at the endpoint could change.

The best way I know to sort HTML table with javascript is with the following function.

Just pass to it the id of the table you'd like to sort and the column number on the row. it assumes that the column you are sorting is numeric or has numbers in it and will do regex replace to get the number itself (great for currencies and other numbers with symbols in it).

function sortTable(table_id, sortColumn){
    var tableData = document.getElementById(table_id).getElementsByTagName('tbody').item(0);
    var rowData = tableData.getElementsByTagName('tr');            
    for(var i = 0; i < rowData.length - 1; i++){
        for(var j = 0; j < rowData.length - (i + 1); j++){
            if(Number(rowData.item(j).getElementsByTagName('td').item(sortColumn).innerHTML.replace(/[^0-9\.]+/g, "")) < Number(rowData.item(j+1).getElementsByTagName('td').item(sortColumn).innerHTML.replace(/[^0-9\.]+/g, ""))){
                tableData.insertBefore(rowData.item(j+1),rowData.item(j));
            }
        }
    }
}

Using example:

$(function(){
    // pass the id and the <td> place you want to sort by (td counts from 0)
    sortTable('table_id', 3);
});

Just use "\n" in your strings.xml file as below

<string name="relaxing_sounds">RELAXING\nSOUNDS</string>

Even if it doesn't looks 2 lines on layout actually it is 2 lines. Firstly you can check it on Translation Editor

Click the down button and you will see this image

Moreover if you run the app you will see that it is written in two lines.

I think you can't call

 androidHttpTransport.call(SOAP_ACTION, envelope);

on main Thread.

Network operations should be done on different Thread.

Create another Thread or AsyncTask to call the method.

cellspacing (distance between cells) parameter of the TABLE tag is precisely what you want. The disadvantage is it's one value, used both for x and y, you can't choose different spacing or padding vertically/horizontally. There is a CSS property too, but it's not widely supported.

I've a same problem. After move machine from restore of Time Machine, on another host. There problem it's that ssh key for vagrant it's not your key, it's a key on Homestead directory.

Solution for me:

• Use vagrant / vagrant for access ti VM of Homestead
• vagrant ssh-config for see config of ssh

run on terminal

vagrant ssh-config
Host default
HostName 127.0.0.1
User vagrant
Port 2222
UserKnownHostsFile /dev/null
StrictHostKeyChecking no
PasswordAuthentication no
IdentityFile "/Users/MYUSER/.vagrant.d/insecure_private_key"
IdentitiesOnly yes
LogLevel FATAL
ForwardAgent yes

Create a new pair of SSH keys

ssh-keygen -f /Users/MYUSER/.vagrant.d/insecure_private_key

Copy content of public key

cat /Users/MYUSER/.vagrant.d/insecure_private_key.pub

On other shell in Homestead VM Machine copy into authorized_keys

vagrant@homestad:~$ echo 'CONTENT_PASTE_OF_PRIVATE_KEY' >> ~/.ssh/authorized_keys

Now can access with vagrant ssh

At my previous employer, we used custom HTML tags all the time to hold info about the form elements. The catch: We knew that the user was forced to use IE.

It didn't work well for FireFox at the time. I don't know if FireFox has changed this or not, but be aware that adding your own attributes to HTML elements may or may-not be supported by your reader's browser.

If you can control which browser your reader is using (i.e. an internal web applet for a corporation), then by all means, try it. What can it hurt, right?

double *ptr = malloc(sizeof(double *) * TIME);
/* ... */
for(tcount = 0; tcount <= TIME; tcount++)
                         ^^

• You're overstepping the array. Either change <= to < or alloc SIZE + 1 elements
• Your malloc is wrong, you'll want sizeof(double) instead of sizeof(double *)
• As ouah comments, although not directly linked to your corruption problem, you're using *(ptr+tcount) without initializing it

• Just as a style note, you might want to use ptr[tcount] instead of *(ptr + tcount)
• You don't really need to malloc + free since you already know SIZE

If issue remains even after updating dependency version, then delete everything present under

And, make sure following dependencies are present:

And here's a jQuery example:

HTML text field:

<input type="text" id="myTextfield" />

jQuery code to limit its size:

var elem = $("#myTextfield");
if(elem) elem.val(elem.val().substr(0,10));

As an example, you could use the jQuery code above to restrict the user from entering more than 10 characters while he's typing; the following code snippet does exactly this:

$(document).ready(function() {
    var elem = $("#myTextfield");
    if (elem) {
        elem.keydown(function() {
            if (elem.val().length > 10)
                elem.val(elem.val().substr(0, 10));
        });
    }            
});

Update: The above code snippet was only used to show an example usage.

The following code snippet will handle you issue with the DIV element:

$(document).ready(function() {
    var elem = $(".tasks-overflow");
    if(elem){
        if (elem.text().length > 10)
                elem.text(elem.text().substr(0,10))
    }
});

Please note that I'm using text instead of val in this case, since the val method doesn't seem to work with the DIV element.

myString.count('a');

Surround what you want to be bold with:

<span style="font-weight:bold">Your bold text</span>

This would go inside your <td> tag.

You should be able to access your windows system under the /mnt directory. For example inside of bash, use this to get to your pictures directory:

cd /mnt/c/Users/<ubuntu.username>/Pictures

Hope this helps!

• fill_parent will make the width or height of the element to be as large as the parent element, in other words, the container.

• wrap_content will make the width or height be as large as needed to contain the elements within it.

The issue for me was that DocumentFormat.OpenXml.dll existed in the Global Assembly Cache (GAC) on my Win7 development box. So when publishing my project in VS2013, it found the file in the GAC and therefore omitted it from being copied to the publish folder.

Solution: remove the DLL from the GAC.

1. Open the GAC root in Windows Explorer (Win7: %windir%\Microsoft.NET\assembly)
2. Search for OpenXml
3. Delete any appropriate folders (or to be safe, cut them out to your desktop in case you should want to restore them)

There may be a more proper way to remove a GAC file (below), but that is what I did and it worked. gacutil –u DocumentFormat.OpenXml.dll

Hope that helps!

My original reply was factually incorrect and I'm glad it was removed. The code below will work under the following conditions a) you know that nobody else modified the sequence b) the sequence was modified by your session. In my case, I encountered a similar issue where I was calling a procedure which modified a value and I'm confident the assumption is true.

SELECT mysequence.CURRVAL INTO v_myvariable FROM DUAL;

Sadly, if you didn't modify the sequence in your session, I believe others are correct in stating that the NEXTVAL is the only way to go.

If $new_input may contain more than just a 'name' element you may want to use array_merge.

$new_input = array('name'=>array(), 'details'=>array());
$new_input['name'] = array('type'=>'text', 'label'=>'First name'...);
$options['inputs'] = array_merge($options['inputs'], $new_input);

The basic difference :

Linear regression is basically a regression model which means its will give a non discreet/continuous output of a function. So this approach gives the value. For example : given x what is f(x)

For example given a training set of different factors and the price of a property after training we can provide the required factors to determine what will be the property price.

Logistic regression is basically a binary classification algorithm which means that here there will be discreet valued output for the function . For example : for a given x if f(x)>threshold classify it to be 1 else classify it to be 0.

For example given a set of brain tumour size as training data we can use the size as input to determine whether its a benine or malignant tumour. Therefore here the output is discreet either 0 or 1.

*here the function is basically the hypothesis function

You can add new column with the query

ALTER TABLE TableName ADD COLUMN COLNew CHAR(25)

But it will be added at the end, not in between the existing columns.

dateDate.Ticks

should give you what you're looking for.

The value of this property represents the number of 100-nanosecond intervals that have elapsed since 12:00:00 midnight, January 1, 0001, which represents DateTime.MinValue. It does not include the number of ticks that are attributable to leap seconds.

DateTime.Ticks

If you're really looking for the Linux Epoch time (seconds since Jan 1, 1970), the accepted answer for this question should be relevant.

But if you're actually trying to "compress" a string representation of the date into an int, you should ask yourself why aren't you just storing it as a string to begin with. If you still want to do it after that, Stecya's answer is the right one. Keep in mind it won't fit into an int, you'll have to use a long.

I was unable to find JSTool. Please see below url to see how I installed Notepad++

How to view Plugin Manager in Notepad++

I created JSMinNPP folder in C:\Program Files (x86)\Notepad++\plugins and copied JSMinNPP to it.

I think the confusion over here roots from the english. I mean __repr__(); short for 'representation' of the value I'm guessing, like @S.Lott said

"What is the difference between "an actual expression, that can ... recreate the object" and "a rehasing of the actual expression which was used [to create the object]"? Both are an expression that creates the object. There's no practical distinction between these. A repr call could produce either a new expression or the original expression. In many cases, they're the same."

But in some cases they might be different. E.g; coordinate points, you might want c.coordinate to return: 3,5 but c.__repr__ to return Coordinate(3, 5). Hope that makes more sense...

adding HttpClientModule in app.module.ts file in import section fixed my issue.

You can pass in wildcards in instead of specifying file names or using stdin.

You can not return anonymous types directly, but you can loop them through your generic method. So do most of LINQ extension methods. There is no magic in there, while it looks like it they would return anonymous types. If parameter is anonymous result can also be anonymous.

var result = Repeat(new { Name = "Foo Bar", Age = 100 }, 10);

private static IEnumerable<TResult> Repeat<TResult>(TResult element, int count)
{
    for(int i=0; i<count; i++)
    {
        yield return element;
    }
}

Below an example based on code from original question:

var result = GetDogsWithBreedNames((Name, BreedName) => new {Name, BreedName });


public static IQueryable<TResult> GetDogsWithBreedNames<TResult>(Func<object, object, TResult> creator)
{
    var db = new DogDataContext(ConnectString);
    var result = from d in db.Dogs
                    join b in db.Breeds on d.BreedId equals b.BreedId
                    select creator(d.Name, b.BreedName);
    return result;
}

Your command is correct. You just need to add -l to grep:

find / -type f -exec grep -l 'text-to-find-here' {} \;

Note from 2017: File::Slurp is not recommended due to design mistakes and unmaintained errors. Use File::Slurper or Path::Tiny instead.

extending on your answer

use File::Slurp ();
my $value = File::Slurp::slurp($filename);
$value =~ s/\R*//g;

File::Slurp abstracts away the File IO stuff and just returns a string for you.

NOTE

1. Important to note the addition of /g , without it, given a multi-line string, it will only replace the first offending character.

2. Also, the removal of $, which is redundant for this purpose, as we want to strip all line breaks, not just line-breaks before whatever is meant by $ on this OS.

3. In a multi-line string, $ matches the end of the string and that would be problematic ).

4. Point 3 means that point 2 is made with the assumption that you'd also want to use /m otherwise '$' would be basically meaningless for anything practical in a string with >1 lines, or, doing single line processing, an OS which actually understands $ and manages to find the \R* that proceed the $

Examples

while( my $line = <$foo> ){
      $line =~ $regex;
}

Given the above notation, an OS which does not understand whatever your files '\n' or '\r' delimiters, in the default scenario with the OS's default delimiter set for $/ will result in reading your whole file as one contiguous string ( unless your string has the $OS's delimiters in it, where it will delimit by that )

So in this case all of these regex are useless:

• /\R*$// : Will only erase the last sequence of \R in the file
• /\R*// : Will only erase the first sequence of \R in the file

• /\012?\015?// : When will only erase the first 012\015 , \012 , or \015 sequence, \015\012 will result in either \012 or \015 being emitted.

• /\R*$// : If there happens to be no byte sequences of '\015$OSDELIMITER' in the file, then then NO linebreaks will be removed except for the OS's own ones.

It would appear nobody gets what I'm talking about, so here is example code, that is tested to NOT remove line feeds. Run it, you'll see that it leaves the linefeeds in.

#!/usr/bin/perl 

use strict;
use warnings;

my $fn = 'TestFile.txt';

my $LF = "\012";
my $CR = "\015";

my $UnixNL = $LF;
my $DOSNL  = $CR . $LF;
my $MacNL  = $CR;

sub generate { 
    my $filename = shift;
    my $lineDelimiter = shift;

    open my $fh, '>', $filename;
    for ( 0 .. 10 )
    {
        print $fh "{0}";
        print $fh join "", map { chr( int( rand(26) + 60 ) ) } 0 .. 20;
        print $fh "{1}";
        print $fh $lineDelimiter->();
        print $fh "{2}";
    }
    close $fh;
}

sub parse { 
    my $filename = shift;
    my $osDelimiter = shift;
    my $message = shift;
    print "Parsing $message File $filename : \n";

    local $/ = $osDelimiter;

    open my $fh, '<', $filename;
    while ( my $line = <$fh> )
    {

        $line =~ s/\R*$//;
        print ">|" . $line . "|<";

    }
    print "Done.\n\n";
}


my @all = ( $DOSNL,$MacNL,$UnixNL);
generate 'Windows.txt' , sub { $DOSNL }; 
generate 'Mac.txt' , sub { $MacNL };
generate 'Unix.txt', sub { $UnixNL };
generate 'Mixed.txt', sub {
    return @all[ int(rand(2)) ];
};


for my $os ( ["$MacNL", "On Mac"], ["$DOSNL", "On Windows"], ["$UnixNL", "On Unix"]){
    for ( qw( Windows Mac Unix Mixed ) ){
        parse $_ . ".txt", @{ $os };
    }
}

For the CLEARLY Unprocessed output, see here: http://pastebin.com/f2c063d74

Note there are certain combinations that of course work, but they are likely the ones you yourself naívely tested.

Note that in this output, all results must be of the form >|$string|<>|$string|< with NO LINE FEEDS to be considered valid output.

and $string is of the general form {0}$data{1}$delimiter{2} where in all output sources, there should be either :

1. Nothing between {1} and {2}
2. only |<>| between {1} and {2}

npm start will run whatever you have defined for the start command of the scripts object in your package.json file.

So if it looks like this:

"scripts": {
  "start": "ng serve"
}

Then npm start will run ng serve.

For people with only one IP address and multiple sites on one server, you can configure IIS to listen on a port other than 80, e.g 8080 by setting the TCP port in the properties of each of its sites (including the default one).

In Apache, enable mod_proxy and mod_proxy_http, then add a catch-all VirtualHost (after all others) so that requests Apache isn't explicitly handling get "forwarded" on to IIS.

<VirtualHost *:80>
    ServerName foo.bar
    ServerAlias *
    ProxyPreserveHost On
    ProxyPass / http://127.0.0.1:8080/
</VirtualHost>

Now you can have Apache serve some sites and IIS serve others, with no visible difference to the user.

Edit: your IIS sites must not include their port number in any URLs within their responses, including headers.

As of React Native 0.4.2, View components have an onLayout prop. Pass in a function that takes an event object. The event's nativeEvent contains the view's layout.

<View onLayout={(event) => {
  var {x, y, width, height} = event.nativeEvent.layout;
}} />

The onLayout handler will also be invoked whenever the view is resized.

The main caveat is that the onLayout handler is first invoked one frame after your component has mounted, so you may want to hide your UI until you have computed your layout.

jakub.g's answer is correct, however an example using grunt seems a bit complex.

So my simpler answer:

- Sending a command line argument to an npm script

Syntax for sending command line arguments to an npm script:

npm run [command] [-- <args>]

Imagine we have an npm start task in our package.json to kick off webpack dev server:

"scripts": {
  "start": "webpack-dev-server --port 5000"
},

We run this from the command line with npm start

Now if we want to pass in a port to the npm script:

"scripts": {
  "start": "webpack-dev-server --port process.env.port || 8080"
},

running this and passing the port e.g. 5000 via command line would be as follows:

npm start --port:5000

- Using package.json config:

As mentioned by jakub.g, you can alternatively set params in the config of your package.json

"config": {
  "myPort": "5000"
}

"scripts": {
  "start": "webpack-dev-server --port process.env.npm_package_config_myPort || 8080"
},

npm start will use the port specified in your config, or alternatively you can override it

npm config set myPackage:myPort 3000

- Setting a param in your npm script

An example of reading a variable set in your npm script. In this example NODE_ENV

"scripts": {
  "start:prod": "NODE_ENV=prod node server.js",
  "start:dev": "NODE_ENV=dev node server.js"
},

read NODE_ENV in server.js either prod or dev

var env = process.env.NODE_ENV || 'prod'

if(env === 'dev'){
    var app = require("./serverDev.js");
} else {
    var app = require("./serverProd.js");
}

You have to sink "output" and "message" separately (the sink function only looks at the first element of type)

Now if you want the input to be logged too, then put it in a script:

script.R

1:5 + 1:3   # prints and gives a warning
stop("foo") # an error

And at the prompt:

con <- file("test.log")
sink(con, append=TRUE)
sink(con, append=TRUE, type="message")

# This will echo all input and not truncate 150+ character lines...
source("script.R", echo=TRUE, max.deparse.length=10000)

# Restore output to console
sink() 
sink(type="message")

# And look at the log...
cat(readLines("test.log"), sep="\n")

The best way that I've found to revert a min-width setting is:

min-width: 0;
min-width: unset;

unset is in the spec, but some browsers (IE 10) do not respect it, so 0 is a good fallback in most cases. min-width: 0;

For example, if this is a number :

ouloulou={
    1:US,
    2:BR,
    3:FR
    }
ouloulou[1]()

It's work perfectly, but if you use for example :

ouloulou[input("select 1 2 or 3"]()

it's doesn't work, because your input return string '1'. So you need to use int()

ouloulou[int(input("select 1 2 or 3"))]()

Yes, Python does support Short-circuit evaluation, minimal evaluation, or McCarthy evaluation for Boolean operators. It is used to reduce the number of evaluations for computing the output of boolean expression. Example -

Base Functions

def a(x):
    print('a')
    return x

def b(x):
    print('b')
    return x 

AND

if(a(True) and b(True)):
    print(1,end='\n\n')

if(a(False) and b(True)):
    print(2,end='\n\n') 

AND-OUTPUT

a
b
1

a 

OR

if(a(True) or b(False)):
    print(3,end='\n\n')

if(a(False) or b(True)):
    print(4,end='\n\n') 

OR-OUTPUT

a
3

a
b
4 

This script outputs the number of unique values in each column of a given file. It assumes that first line of given file is header line. There is no need for defining number of fields. Simply save the script in a bash file (.sh) and provide the tab delimited file as a parameter to this script.

Code

#!/bin/bash

awk '
(NR==1){
    for(fi=1; fi<=NF; fi++)
        fname[fi]=$fi;
} 
(NR!=1){
    for(fi=1; fi<=NF; fi++) 
        arr[fname[fi]][$fi]++;
} 
END{
    for(fi=1; fi<=NF; fi++){
        out=fname[fi];
        for (item in arr[fname[fi]])
            out=out"\t"item"_"arr[fname[fi]][item];
        print(out);
    }
}
' $1

Execution Example:

bash> ./script.sh <path to tab-delimited file>

Output Example

isRef    A_15      C_42     G_24     T_18
isCar    YEA_10    NO_40    NA_50
isTv     FALSE_33  TRUE_66

I always use requestAnimationFrame() to jump over internal post-event mechanisms and this works perfectly in Firefox. Haven't tested in Chrome.

$("input[type=text]").on('focus', function() {
    requestAnimationFrame(() => $(this).select());
});

I ended up here looking to delete my node_modules folders before doing a backup of my work in progress using rsync. A key requirements is that the node_modules folder can be nested, so you need the -prune option.

First I ran this to visually verify the folders to be deleted:

find -type d -name node_modules -prune

Then I ran this to delete them all:

find -type d -name node_modules -prune -exec rm -rf {} \;

Thanks to pistache

Here's an improvement to Gavin's answer. marcp's solution is similar also, but neither postpone the division.

This actually turns out to be a practical application of Gareth Rees' answer as well, because the cross-product's equivalent in 2D is the perp-dot-product, which is what this code uses three of. Switching to 3D and using the cross-product, interpolating both s and t at the end, results in the two closest points between the lines in 3D. Anyway, the 2D solution:

int get_line_intersection(float p0_x, float p0_y, float p1_x, float p1_y, 
    float p2_x, float p2_y, float p3_x, float p3_y, float *i_x, float *i_y)
{
    float s02_x, s02_y, s10_x, s10_y, s32_x, s32_y, s_numer, t_numer, denom, t;
    s10_x = p1_x - p0_x;
    s10_y = p1_y - p0_y;
    s32_x = p3_x - p2_x;
    s32_y = p3_y - p2_y;

    denom = s10_x * s32_y - s32_x * s10_y;
    if (denom == 0)
        return 0; // Collinear
    bool denomPositive = denom > 0;

    s02_x = p0_x - p2_x;
    s02_y = p0_y - p2_y;
    s_numer = s10_x * s02_y - s10_y * s02_x;
    if ((s_numer < 0) == denomPositive)
        return 0; // No collision

    t_numer = s32_x * s02_y - s32_y * s02_x;
    if ((t_numer < 0) == denomPositive)
        return 0; // No collision

    if (((s_numer > denom) == denomPositive) || ((t_numer > denom) == denomPositive))
        return 0; // No collision
    // Collision detected
    t = t_numer / denom;
    if (i_x != NULL)
        *i_x = p0_x + (t * s10_x);
    if (i_y != NULL)
        *i_y = p0_y + (t * s10_y);

    return 1;
}

Basically it postpones the division until the last moment, and moves most of the tests until before certain calculations are done, thereby adding early-outs. Finally, it also avoids the division by zero case which occurs when the lines are parallel.

You also might want to consider using an epsilon test rather than comparison against zero. Lines that are extremely close to parallel can produce results that are slightly off. This is not a bug, it is a limitation with floating point math.

Given your simple question: "In javascript, when would you want to use this:..."

I like @ken_browning and @sean_holding's answers, but here's another use-case that I don't see mentioned:

let red_tree = new Node(10);

(async function () {
    for (let i = 0; i < 1000; i++) {
        await red_tree.insert(i);
    }
})();

console.log('----->red_tree.printInOrder():', red_tree.printInOrder());

where Node.insert is some asynchronous action.

I can't just call await without the async keyword at the declaration of my function, and i don't need a named function for later use, but need to await that insert call or i need some other richer features (who knows?).

Simple change to syntax is all that is needed:

 create table ImagenesUsuario (
   idImagen int not null identity(1,1) primary key
 )

By explicitly using the "constraint" keyword, you can give the primary key constraint a particular name rather than depending on SQL Server to auto-assign a name:

 create table ImagenesUsuario (
   idImagen int not null identity(1,1) constraint pk_ImagenesUsario primary key
 )

Add the "CLUSTERED" keyword if that makes the most sense based on your use of the table (i.e., the balance of searches for a particular idImagen and amount of writing outweighs the benefits of clustering the table by some other index).

It seem like your Resort method doesn't declare a compareTo method. This method typically belongs to the Comparable interface. Make sure your class implements it.

Additionally, the compareTo method is typically implemented as accepting an argument of the same type as the object the method gets invoked on. As such, you shouldn't be passing a String argument, but rather a Resort.

Alternatively, you can compare the names of the resorts. For example

if (resortList[mid].getResortName().compareTo(resortName)>0)  

You just need to keep track of a max value like this:

int maxValue = 0;

Then as you iterate through the numbers, keep setting the maxValue to the next value if it is greater than the maxValue:

if (value > maxValue) {
    maxValue = value;
}

Repeat in the opposite direction for minValue.

You may do this with a for loop instead of a while:

max_loop=20
for ((count = 0; count < max_loop; count++)); do
  if /home/hadoop/latest/bin/hadoop fs -ls /apps/hdtech/bds/quality-rt/dt=$DATE_YEST_FORMAT2 then
       echo "Files Present" | mailx -s "File Present"  -r [email protected] [email protected]
       break
  else
       echo "Sleeping for half an hour" | mailx -s "Time to Sleep Now"  -r [email protected] [email protected]
       sleep 1800
  fi
done

if [ "$count" -eq "$max_loop" ]; then
  echo "Maximum number of trials reached" >&2
  exit 1
fi

$("#test").hide(100, function() {

_{This is the first google hit for "python test empty array" and similar queries, plus other people seem to be generalizing the question beyond just lists, so I thought I'd add a caveat for a different type of sequence that a lot of people might use.}

Other methods don't work for NumPy arrays

You need to be careful with NumPy arrays, because other methods that work fine for lists or other standard containers fail for NumPy arrays. I explain why below, but in short, the preferred method is to use size.

The "pythonic" way doesn't work: Part 1

The "pythonic" way fails with NumPy arrays because NumPy tries to cast the array to an array of bools, and if x tries to evaluate all of those bools at once for some kind of aggregate truth value. But this doesn't make any sense, so you get a ValueError:

>>> x = numpy.array([0,1])
>>> if x: print("x")
ValueError: The truth value of an array with more than one element is ambiguous. Use a.any() or a.all()

The "pythonic" way doesn't work: Part 2

But at least the case above tells you that it failed. If you happen to have a NumPy array with exactly one element, the if statement will "work", in the sense that you don't get an error. However, if that one element happens to be 0 (or 0.0, or False, ...), the if statement will incorrectly result in False:

>>> x = numpy.array([0,])
>>> if x: print("x")
... else: print("No x")
No x

But clearly x exists and is not empty! This result is not what you wanted.

Using len can give unexpected results

For example,

len( numpy.zeros((1,0)) )

returns 1, even though the array has zero elements.

The numpythonic way

As explained in the SciPy FAQ, the correct method in all cases where you know you have a NumPy array is to use if x.size:

>>> x = numpy.array([0,1])
>>> if x.size: print("x")
x

>>> x = numpy.array([0,])
>>> if x.size: print("x")
... else: print("No x")
x

>>> x = numpy.zeros((1,0))
>>> if x.size: print("x")
... else: print("No x")
No x

If you're not sure whether it might be a list, a NumPy array, or something else, you could combine this approach with the answer @dubiousjim gives to make sure the right test is used for each type. Not very "pythonic", but it turns out that NumPy intentionally broke pythonicity in at least this sense.

If you need to do more than just check if the input is empty, and you're using other NumPy features like indexing or math operations, it's probably more efficient (and certainly more common) to force the input to be a NumPy array. There are a few nice functions for doing this quickly — most importantly numpy.asarray. This takes your input, does nothing if it's already an array, or wraps your input into an array if it's a list, tuple, etc., and optionally converts it to your chosen dtype. So it's very quick whenever it can be, and it ensures that you just get to assume the input is a NumPy array. We usually even just use the same name, as the conversion to an array won't make it back outside of the current scope:

x = numpy.asarray(x, dtype=numpy.double)

This will make the x.size check work in all cases I see on this page.

Just adding one more point

Using app.config some how you can control application access, you want apply particular change to entire application use app config file and you can access the settings like below ConfigurationSettings.AppSettings["Key"]

Manoj answer above is correct, but another option is to use MESSAGE.encode() or encode('utf-8') to convert to bytes. bytes and encode are mostly the same, encode is compatible with python 2. see here for more

full code:

import socket

UDP_IP = "127.0.0.1"
UDP_PORT = 5005
MESSAGE = "Hello, World!"

print("UDP target IP: %s" % UDP_IP)
print("UDP target port: %s" % UDP_PORT)
print("message: %s" % MESSAGE)

sock = socket.socket(socket.AF_INET, # Internet
                     socket.SOCK_DGRAM) # UDP
sock.sendto(MESSAGE.encode(), (UDP_IP, UDP_PORT))

You are using wrong formatting sequence for double, you should use %lf instead of %ld:

double a;
scanf("%lf",&a);

$timestamp = strtotime($row['DATETIMEAPP']);

gives you timestamp, which then you can use date to format:

$date = date('d-m-Y', $timestamp);
$time = date('Gi.s', $timestamp);

Alternatively

list($date, $time) = explode('|', date('d-m-Y|Gi.s', $timestamp));

I had the same thing in both Chrome and Safari aka Webkit browsers. I'm suspecting it's not a bug, but the incorrect use of css which 'breaks' the background.

In the Question above, the body background property is set to:

background: black;

Which is fine, but not entirely correct. There's no image background, thus...

background-color: black;

For the go up, you just need to use scrollTop instead of scrollBottom:

$("#upClick").on("click", function () {
    scrolled = scrolled - 300;
    $(".cover").stop().animate({
        scrollTop: scrolled
    });
});

Also, use the .stop() method to stop the currently-running animation on the cover div. When .stop() is called on an element, the currently-running animation (if any) is immediately stopped.

You're probably targeting the Client Profile, in which System.Web.dll is not available.

You can target the full framework in project's Properties.

lastInsertId() only work after the INSERT query.

Correct:

$stmt = $this->conn->prepare("INSERT INTO users(userName,userEmail,userPass) 
                              VALUES(?,?,?);");
$sonuc = $stmt->execute([$username,$email,$pass]);
$LAST_ID = $this->conn->lastInsertId();

Incorrect:

$stmt = $this->conn->prepare("SELECT * FROM users");
$sonuc = $stmt->execute();
$LAST_ID = $this->conn->lastInsertId(); //always return string(1)=0

Stash is just a convenience method. Since branches are so cheap and easy to manage in git, I personally almost always prefer creating a new temporary branch than stashing, but it's a matter of taste mostly.

The one place I do like stashing is if I discover I forgot something in my last commit and have already started working on the next one in the same branch:

# Assume the latest commit was already done
# start working on the next patch, and discovered I was missing something

# stash away the current mess I made
git stash save

# some changes in the working dir

# and now add them to the last commit:
git add -u
git commit --amend

# back to work!
git stash pop

Further to the other answers suggesting LINQ, another alternative in this case would be to use the FindAll instance method:

List<SampleClass> results = myList.FindAll(x => x.Name == nameToExtract);

In my case, I see the window, but no messages in it. Only restart (studio version 1.5.1) brought the messages back.

I am trying to get recursion too.

I found a way i think,

i think of it like a chain of steps(the step isnt constant it may change depending on the previous node)

I have to figure out 2 things:

1. previous node
2. step kind
3. after the step what else before call(this is the argument for the next call

example

factorial

1,2,6,24,120 ......... or

1,2*(1),3*(2*1),4*(3*2*1,5*(4*3*2*1)

step=multiple by last node

after the step what i need to get to the next node,abstract 1

ok

function =

n*f(n-1) 

its 2 steps process
from a-->to step--->b

i hoped this help,just think about 2 thniks,not how to get from node to node,but node-->step-->node

node-->step is the body of the function step-->node is the arguments of the other function

bye:) hope i helped

This is what worked for my, and its pure css

For SQL Server use exec sp_help

USE db_name;
exec sp_help 'dbo.table_name'

For MySQL, use describe

DESCRIBE table_name;

If the database engine for tables differ you will get this error so change them to InnoDB

ALTER TABLE my_table ENGINE = InnoDB;

In my case I fixed this issue like below:-

1. First I removed (apache) C:\Users\myuserId\.m2\repository\org\apache

2. I added below dependencies in my pom.xml file

   <dependency>
       <groupId>org.springframework.boot</groupId>
       <artifactId>spring-boot-starter-web</artifactId>
   </dependency>
   

3. I have changed the default socket by adding below lines in resource file ..\yourprojectfolder\src\main\resourcesand\application.properties(I manually created this file)

    server.port=8099
    [email protected]@
   

   for that I have added below block in my pom.xml under <build> section.

     <build>
     .
     .
    <resources>
       <resource>
           <directory>src/main/resources</directory>

Here's an idea using Object.defineProperty which directly modifies the way a property is accessed.

Code:

function bind(base, el, varname) {
    Object.defineProperty(base, varname, {
        get: () => {
            return el.value;
        },
        set: (value) => {
            el.value = value;
        }
    })
}

Usage:

var p = new some_class();
bind(p,document.getElementById("someID"),'variable');

p.variable="yes"

fiddle: Here

{% for days in days_list %}
    <h2># Day {{ forloop.counter }} - From {{ days.from_location }} to {{ days.to_location }}</h2>
{% endfor %}

or if you want to start from 0

{% for days in days_list %}
        <h2># Day {{ forloop.counter0 }} - From {{ days.from_location }} to {{ days.to_location }}</h2>
    {% endfor %}

Just to clarify this: if we have a RadioGroup with several RadioButtons and need to activate one by index, implies that:

radioGroup.check(R.id.radioButtonId)

and

radioGroup.getChildAt(index)`

We can to do:

radioGroup.check(radioGroup.getChildAt(index).getId());

The -p approach works well, but you do have to remember to use it every time. If your goal is to switch to a newer version of Python generally, that's a pain and can also lead to mistakes.

Your other option is to set an environment variable that does the same thing as -p. Set this via your ~/.bashrc file or wherever you manage environment variables for your login sessions:

export VIRTUALENV_PYTHON=/path/to/desired/version

Then virtualenv will use that any time you don't specify -p on the command line.

I had something similar, and here's (an edited) version of what I ended up using successfully:

ISNULL(CONVERT(VARCHAR(50),[column name goes here],[date style goes here] ),'')

Here's why this works: If you select a date which is NULL, it will show return NULL, though it is really stored as 01/01/1900. This is why an ISNULL on the date field, while you're working with any date data type will not treat this as a NULL, as it is technically not being stored as a NULL.

However, once you convert it to a new datatype, it will convert it as a NULL, and at that point, you're ISNULL will work as you expect it to work.

I hope this works out for you as well!

~Eli

Update, nearly one year later:

I had a similar situation, where I needed the output to be of the date data-type, and my aforementioned solution didn't work (it only works if you need it displayed as a date, not be of the date data type.

If you need it to be of the date data-type, there is a way around it, and this is to nest a REPLACE within an ISNULL, the following worked for me:

Select 
    ISNULL(
        REPLACE(
            [DATE COLUMN NAME],
            '1900-01-01',
            ''
        ),
    '') AS [MeaningfulAlias]

Defining constants by using preprocessor directive #define is not recommended to apply not only in C++, but also in C. These constants will not have the type. Even in C was proposed to use const for constants.

I was able to solve it by clicking on the "Kernel" drop down menu and choosing "Interrupt."

If you are developing for Android, Color's method for this is rgb(int, int, int)

So you would do something like

myPaint.setColor(Color.rgb(int, int, int)); 

For retrieving the individual color values you can use the methods for doing so:

Color.red(int color) 
Color.blue(int color) 
Color.green(int color)

The best way to define a class in JavaScript is to not define a class.

Seriously.

There are several different flavors of object-orientation, some of them are:

• class-based OO (first introduced by Smalltalk)
• prototype-based OO (first introduced by Self)
• multimethod-based OO (first introduced by CommonLoops, I think)
• predicate-based OO (no idea)

And probably others I don't know about.

JavaScript implements prototype-based OO. In prototype-based OO, new objects are created by copying other objects (instead of being instantiated from a class template) and methods live directly in objects instead of in classes. Inheritance is done via delegation: if an object doesn't have a method or property, it is looked up on its prototype(s) (i.e. the object it was cloned from), then the prototype's prototypes and so on.

In other words: there are no classes.

JavaScript actually has a nice tweak of that model: constructors. Not only can you create objects by copying existing ones, you can also construct them "out of thin air", so to speak. If you call a function with the new keyword, that function becomes a constructor and the this keyword will not point to the current object but instead to a newly created "empty" one. So, you can configure an object any way you like. In that way, JavaScript constructors can take on one of the roles of classes in traditional class-based OO: serving as a template or blueprint for new objects.

Now, JavaScript is a very powerful language, so it is quite easy to implement a class-based OO system within JavaScript if you want to. However, you should only do this if you really have a need for it and not just because that's the way Java does it.

Thanks Philip this helped me - my use case was I had a form with lot of input fields so I maintained initial state as object and I was not able to update the object state.The above post helped me :)

const [projectGroupDetails, setProjectGroupDetails] = useState({
    "projectGroupId": "",
    "projectGroup": "DDD",
    "project-id": "",
    "appd-ui": "",
    "appd-node": ""    
});

const inputGroupChangeHandler = (event) => {
    setProjectGroupDetails((prevState) => ({
       ...prevState,
       [event.target.id]: event.target.value
    }));
}

<Input 
    id="projectGroupId" 
    labelText="Project Group Id" 
    value={projectGroupDetails.projectGroupId} 
    onChange={inputGroupChangeHandler} 
/>

For those using AngularJS, there is also direct method for cloning or extending of the objects in this library.

var destination = angular.copy(source);

or

angular.copy(source, destination);

More in angular.copy documentation...

FYI

Using netbeans New Entity Classes from Database with a mysql *auto_increment* column, creates you an attribute with the following annotations:

@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Basic(optional = false)
@Column(name = "id")
@NotNull
private Integer id;

This was getting me the same an error saying the column must not be null, so i simply removed the @NotNull anotation leaving the attribute null, and it works!

You can also add opacity to your overlay color.

Instead of doing

background: url('../img/bg/diagonalnoise.png');
background-color: rgba(248, 247, 216, 0.7);

You can do:

background: url('../img/bg/diagonalnoise.png');

Then create a new style for the opacity color:

.colorStyle{
    background-color: rgba(248, 247, 216, 0.7);
    opacity: 0.8;
}

Change the opacity to whatever number you want below 1. Then you make this color style the same size as your image. It should work.

A word of caution regarding handrolled approaches:

I'm disappointed to see that some of the suggested code examples in this post do not protect against such fundamental authentication vulnerabilities such as session fixation or timing attacks.

Contrary to several suggestions here, authentication is not simple and handrolling a solution is not always trivial. I would recommend passportjs and bcrypt.

If you do decide to handroll a solution however, have a look at the express js provided example for inspiration.

Good luck.

The real answer is : It depends

There are a couple factors to consider, the most obvious are : the cpu you are running these algorithms on and the implementation of the algorithms.

For instance, me and my friend both run the exact same openssl version and get slightly different results with different Intel Core i7 cpus.

My test at work with an Intel(R) Core(TM) i7-2600 CPU @ 3.40GHz

The 'numbers' are in 1000s of bytes per second processed.
type             16 bytes     64 bytes    256 bytes   1024 bytes   8192 bytes
md5              64257.97k   187370.26k   406435.07k   576544.43k   649827.67k
sha1             73225.75k   202701.20k   432679.68k   601140.57k   679900.50k

And his with an Intel(R) Core(TM) i7 CPU 920 @ 2.67GHz

The 'numbers' are in 1000s of bytes per second processed.
type             16 bytes     64 bytes    256 bytes   1024 bytes   8192 bytes
md5              51859.12k   156255.78k   350252.00k   513141.73k   590701.52k
sha1             56492.56k   156300.76k   328688.76k   452450.92k   508625.68k

We both are running the exact same binaries of OpenSSL 1.0.1j 15 Oct 2014 from the ArchLinux official package.

My opinion on this is that with the added security of sha1, cpu designers are more likely to improve the speed of sha1 and more programmers will be working on the algorithm's optimization than md5sum.

I guess that md5 will no longer be used some day since it seems that it has no advantage over sha1. I also tested some cases on real files and the results were always the same in both cases (likely limited by disk I/O).

md5sum of a large 4.6GB file took the exact same time than sha1sum of the same file, same goes with many small files (488 in the same directory). I ran the tests a dozen times and they were consitently getting the same results.

--

It would be very interesting to investigate this further. I guess there are some experts around that could provide a solid answer to why sha1 is getting faster than md5 on newer processors.

I think I should share my experience with you all. Well I see in some situations REMOTE_ADDR will NOT get you what you are looking for. For instance, if you have a Load Balancer behind the scene and if you are trying to get the Client's IP then you will be in trouble. I checked it with my IP masking software plus I also checked with my colleagues being in different continents. So here is my solution.

When I want to know the IP of a client, I try to pick every possible evidence so I could determine if they are unique:

Here I found another sever-var that could help you all if you want to get exact IP of the client side. so I am using : HTTP_X_CLUSTER_CLIENT_IP

HTTP_X_CLUSTER_CLIENT_IP always gets you the exact IP of the client. In any case if its not giving you the value, you should then look for HTTP_X_FORWARDED_FOR as it is the second best candidate to get you the client IP and then the REMOTE_ADDR var which may or may not return you the IP but to me having all these three is what I find the best thing to monitor them.

I hope this helps some guys.

Solution for Jupyter notebook PIL image visualization with arbitrary number of images:

def show(*imgs, **kwargs):
    '''Show in Jupyter notebook one or sequence of PIL images in a row. figsize - optional parameter, controlling size of the image.
    Examples:
    show(img)
    show(img1,img2,img3)
    show(img1,img2,figsize=[8,8])
    '''
    
    if 'figsize' not in kwargs:
        figsize = [9,9]
    else:
        figsize = kwargs['figsize']
    
    fig, ax = plt.subplots(1,len(imgs),figsize=figsize)
    if len(imgs)==1:
        ax=[ax]
    
    for num,img in enumerate(imgs):
        ax[num].imshow(img)
        ax[num].axis('off')
        
    tight_layout()

you must use [ngModel] instead of two way model binding with [(ngModel)]. then use manual change event with (ngModelChange). this is public rule for all two way input in components.

because pipe on event emitter is wrong.

In case you are using WPF and Xceed's TimePicker (which seems to be using DateTime?) as a timespan picker -as I do right now- you can get the total milliseconds (or a TimeSpan) out of it like so:

var milliseconds = DateTimeToTimeSpan(timePicker.Value).TotalMilliseconds;

    TimeSpan DateTimeToTimeSpan(DateTime? ts)
    {
        if (!ts.HasValue) return TimeSpan.Zero;
        else return new TimeSpan(0, ts.Value.Hour, ts.Value.Minute, ts.Value.Second, ts.Value.Millisecond);
    }

XAML :

<Xceed:TimePicker x:Name="timePicker" Format="Custom" FormatString="H'h 'm'm 's's'" />

If not, I guess you could just adjust my DateTimeToTimeSpan() so that it also takes 'days' into account or do sth like dateTime.Substract(DateTime.MinValue).TotalMilliseconds.

Use isinstance(object, type). As above this is easy to use if you know the correct type, e.g.,

isinstance('dog', str) ## gives bool True

But for more esoteric objects, this can be difficult to use. For example:

import numpy as np 
a = np.array([1,2,3]) 
isinstance(a,np.array) ## breaks

but you can do this trick:

y = type(np.array([1]))
isinstance(a,y) ## gives bool True 

So I recommend instantiating a variable (y in this case) with a type of the object you want to check (e.g., type(np.array())), then using isinstance.

With Prototype, you can also do:

HTML:

<ul id="mylist"></ul>

JS:

$('mylist').insert('<li>text</li>');

Try this ls -d */ to list directories within the current directory

Looks like this bug has been around for quite a while! Here are some bug references you may find helpful (and may want to subscribe to / vote up, hint, hint...):

Debian bug #85123 ("sudo: SECURE_PATH still can't be overridden") (from 2001!)

It seems that Bug#20996 is still present in this version of sudo. The changelog says that it can be overridden at runtime but I haven't yet discovered how.

They mention putting something like this in your sudoers file:

Defaults secure_path="/bin:/usr/bin:/usr/local/bin"

but when I do that in Ubuntu 8.10 at least, it gives me this error:

visudo: unknown defaults entry `secure_path' referenced near line 10

Ubuntu bug #50797 ("sudo built with --with-secure-path is problematic")

Worse still, as far as I can tell, it is impossible to respecify secure_path in the sudoers file. So if, for example, you want to offer your users easy access to something under /opt, you must recompile sudo.

---

Yes. There needs to be a way to override this "feature" without having to recompile. Nothing worse then security bigots telling you what's best for your environment and then not giving you a way to turn it off.

---

This is really annoying. It might be wise to keep current behavior by default for security reasons, but there should be a way of overriding it other than recompiling from source code! Many people ARE in need of PATH inheritance. I wonder why no maintainers look into it, which seems easy to come up with an acceptable solution.

---

I worked around it like this:

mv /usr/bin/sudo /usr/bin/sudo.orig

then create a file /usr/bin/sudo containing the following:

#!/bin/bash
/usr/bin/sudo.orig env PATH=$PATH "$@"

then your regular sudo works just like the non secure-path sudo

Ubuntu bug #192651 ("sudo path is always reset")

Given that a duplicate of this bug was originally filed in July 2006, I'm not clear how long an ineffectual env_keep has been in operation. Whatever the merits of forcing users to employ tricks such as that listed above, surely the man pages for sudo and sudoers should reflect the fact that options to modify the PATH are effectively redundant.

Modifying documentation to reflect actual execution is non destabilising and very helpful.

Ubuntu bug #226595 ("impossible to retain/specify PATH")

I need to be able to run sudo with additional non-std binary folders in the PATH. Having already added my requirements to /etc/environment I was surprised when I got errors about missing commands when running them under sudo.....

I tried the following to fix this without sucess:

1. Using the "sudo -E" option - did not work. My existing PATH was still reset by sudo

2. Changing "Defaults env_reset" to "Defaults !env_reset" in /etc/sudoers -- also did not work (even when combined with sudo -E)

3. Uncommenting env_reset (e.g. "#Defaults env_reset") in /etc/sudoers -- also did not work.

4. Adding 'Defaults env_keep += "PATH"' to /etc/sudoers -- also did not work.

Clearly - despite the man documentation - sudo is completely hardcoded regarding PATH and does not allow any flexibility regarding retaining the users PATH. Very annoying as I can't run non-default software under root permissions using sudo.

JSch library is the powerful library that can be used to read file from SFTP server. Below is the tested code to read file from SFTP location line by line

JSch jsch = new JSch();
        Session session = null;
        try {
            session = jsch.getSession("user", "127.0.0.1", 22);
            session.setConfig("StrictHostKeyChecking", "no");
            session.setPassword("password");
            session.connect();

            Channel channel = session.openChannel("sftp");
            channel.connect();
            ChannelSftp sftpChannel = (ChannelSftp) channel;

            InputStream stream = sftpChannel.get("/usr/home/testfile.txt");
            try {
                BufferedReader br = new BufferedReader(new InputStreamReader(stream));
                String line;
                while ((line = br.readLine()) != null) {
                    System.out.println(line);
                }

            } catch (IOException io) {
                System.out.println("Exception occurred during reading file from SFTP server due to " + io.getMessage());
                io.getMessage();

            } catch (Exception e) {
                System.out.println("Exception occurred during reading file from SFTP server due to " + e.getMessage());
                e.getMessage();

            }

            sftpChannel.exit();
            session.disconnect();
        } catch (JSchException e) {
            e.printStackTrace();
        } catch (SftpException e) {
            e.printStackTrace();
        }

Please refer the blog for whole program.

Here's a quick code snippet that will find the first non-empty line in a string:

string line1;
while (
    ((line1 = sr.ReadLine()) != null) &&
    ((line1 = line1.Trim()).Length == 0)
)
{ /* Do nothing - just trying to find first non-empty line*/ }

if(line1 == null){ /* Error - no non-empty lines in string */ }

A clustered index alters the way that the rows are stored. When you create a clustered index on a column (or a number of columns), SQL server sorts the table’s rows by that column(s). It is like a dictionary, where all words are sorted in alphabetical order in the entire book.

A non-clustered index, on the other hand, does not alter the way the rows are stored in the table. It creates a completely different object within the table that contains the column(s) selected for indexing and a pointer back to the table’s rows containing the data. It is like an index in the last pages of a book, where keywords are sorted and contain the page number to the material of the book for faster reference.

Coversion from string to double can be achieved by using the 'strtod()' function from the library 'stdlib.h'

#include <iostream>
#include <stdlib.h>
int main () 
{
    std::string data="20.9";
    double value = strtod(data.c_str(), NULL);
    std::cout<<value<<'\n';
    return 0;
}

I followed steps in below link - https://medium.com/@euedofia/fix-default-java-version-on-maven-on-mac-os-x-156cf5930078 and it worked for me.

cd /usr/local/Cellar/maven/3.5.4/bin/
nano mvn
--Update JAVA_HOME -> "${JAVA_HOME:-$(/usr/libexec/java_home)}"
mvn -version

public void breadthFirstSearch(Node root, Consumer<String> c) {
    List<Node> queue = new LinkedList<>();

    queue.add(root);

    while (!queue.isEmpty()) {
        Node n = queue.remove(0);
        c.accept(n.value);

        if (n.left != null)
            queue.add(n.left);
        if (n.right != null)
            queue.add(n.right);
    }
}

And the Node:

public static class Node {
    String value;
    Node left;
    Node right;

    public Node(final String value, final Node left, final Node right) {
        this.value = value;
        this.left = left;
        this.right = right;
    }
}

I needed to make sure that my scripts are entirely portable between various machines, shells and even cygwin versions. Further, my colleagues who were the ones I had to write the scripts for, are programmers, so I ended up using this:

for ((i=1;i<=$#;i++)); 
do

    if [ ${!i} = "-s" ] 
    then ((i++)) 
        var1=${!i};

    elif [ ${!i} = "-log" ];
    then ((i++)) 
        logFile=${!i};  

    elif [ ${!i} = "-x" ];
    then ((i++)) 
        var2=${!i};    

    elif [ ${!i} = "-p" ]; 
    then ((i++)) 
        var3=${!i};

    elif [ ${!i} = "-b" ];
    then ((i++)) 
        var4=${!i};

    elif [ ${!i} = "-l" ];
    then ((i++)) 
        var5=${!i}; 

    elif [ ${!i} = "-a" ];
    then ((i++)) 
        var6=${!i};
    fi

done;

Rationale: I included a launcher.sh script as well, since the whole operation had several steps which were quasi independent on each other (I'm saying "quasi", because even though each script could be run on its own, they were usually all run together), and in two days I found out, that about half of my colleagues, being programmers and all, were too good to be using the launcher file, follow the "usage", or read the HELP which was displayed every time they did something wrong and they were making a mess of the whole thing, running scripts with arguments in the wrong order and complaining that the scripts didn't work properly. Being the choleric I am I decided to overhaul all my scripts to make sure that they are colleague-proof. The code segment above was the first thing.

I use to have that problem, but the simples way to fix it is this (this works for me):

on the CSS file type:

body{overflow-y:scroll;}

as that simple! :)

Java 8+

Encode or decode byte arrays:

byte[] encoded = Base64.getEncoder().encode("Hello".getBytes());
println(new String(encoded));   // Outputs "SGVsbG8="

byte[] decoded = Base64.getDecoder().decode(encoded);
println(new String(decoded))    // Outputs "Hello"

Or if you just want the strings:

String encoded = Base64.getEncoder().encodeToString("Hello".getBytes());
println(encoded);   // Outputs "SGVsbG8="

String decoded = new String(Base64.getDecoder().decode(encoded.getBytes()));
println(decoded)    // Outputs "Hello"

For more info, see Base64.

Java < 8

Base64 is not bundled with Java versions less than 8. I recommend using Apache Commons Codec.

For direct byte arrays:

Base64 codec = new Base64();
byte[] encoded = codec.encode("Hello".getBytes());
println(new String(encoded));   // Outputs "SGVsbG8="

byte[] decoded = codec.decode(encoded);
println(new String(decoded))    // Outputs "Hello"

Or if you just want the strings:

Base64 codec = new Base64();
String encoded = codec.encodeBase64String("Hello".getBytes());
println(encoded);   // Outputs "SGVsbG8="

String decoded = new String(codec.decodeBase64(encoded));
println(decoded)    // Outputs "Hello"

Spring

If you're working in a Spring project already, you may find their org.springframework.util.Base64Utils class more ergonomic:

For direct byte arrays:

byte[] encoded = Base64Utils.encode("Hello".getBytes());
println(new String(encoded))    // Outputs "SGVsbG8="

byte[] decoded = Base64Utils.decode(encoded);
println(new String(decoded))    // Outputs "Hello"

Or if you just want the strings:

String encoded = Base64Utils.encodeToString("Hello".getBytes());
println(encoded);   // Outputs "SGVsbG8="

String decoded = Base64Utils.decodeFromString(encoded);
println(new String(decoded))    // Outputs "Hello"

Android (with Java < 8)

If you are using the Android SDK before Java 8 then your best option is to use the bundled android.util.Base64.

For direct byte arrays:

byte[] encoded = Base64.encode("Hello".getBytes());
println(new String(encoded))    // Outputs "SGVsbG8="

byte [] decoded = Base64.decode(encoded);
println(new String(decoded))    // Outputs "Hello"

Or if you just want the strings:

String encoded = Base64.encodeToString("Hello".getBytes());
println(encoded);   // Outputs "SGVsbG8="

String decoded = new String(Base64.decode(encoded));
println(decoded)    // Outputs "Hello"

For just counting the lines use:

$handle = fopen("file","r");
static $b = 0;
while($a = fgets($handle)) {
    $b++;
}
echo $b;

You missed the each= argument to rep():

R> n <- 3
R> rep(1:5, each=n)
 [1] 1 1 1 2 2 2 3 3 3 4 4 4 5 5 5
R> 

so your example can be done with a simple

R> rep(1:8, each=20)

The above answers work fine too, but I've found you can usually just use message.author.send("blah blah") instead of message.author.sendMessage("blah blah").

-EDIT- : This is because the sendMessage command is outdated as of v12 in Discord Js

.send tends to work better for me in general than .sendMessage, which sometimes runs into problems. Hope that helps a teeny bit!

Try this code, hope it will help you

String regex = "(\\d+)(\\.)?(\\d+)?";  for integer and decimal like 232 232.12 

Here is a command that gives you all tracking branches (configured for 'pull'), see:

$ git branch -vv
  main   aaf02f0 [main/master: ahead 25] Some other commit
* master add0a03 [jdsumsion/master] Some commit

You have to wade through the SHA and any long-wrapping commit messages, but it's quick to type and I get the tracking branches aligned vertically in the 3rd column.

If you need info on both 'pull' and 'push' configuration per branch, see the other answer on git remote show origin.

Update

Starting in git version 1.8.5 you can show the upstream branch with git status and git status -sb

You can use GCD (in the example with a 10 second delay):

Swift 2

let triggerTime = (Int64(NSEC_PER_SEC) * 10)
dispatch_after(dispatch_time(DISPATCH_TIME_NOW, triggerTime), dispatch_get_main_queue(), { () -> Void in
    self.functionToCall()
})

Swift 3 and Swift 4

DispatchQueue.main.asyncAfter(deadline: .now() + 10.0, execute: {
    self.functionToCall()
})

Swift 5 or Later

 DispatchQueue.main.asyncAfter(deadline: .now() + 10.0) {
        //call any function
    }

You probably want the isinstance builtin function:

self.data = data if isinstance(data, list) else self.parse(data)

USE This Assembly Referance in your Project

Add a reference to System.Net.Http.Formatting.dll

The best practice for this sort of situation is to create a method that hold all the logics, and call the method in both events, rather than calling an event from another event;

Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click

        LogicMethod()

End Sub

Protected Sub Button2_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click

        LogicMethod()

End Sub

Private Sub LogicMethod()

     // All your logic goes here

End Sub

In case you need the properties of the EventArgs (e), you can easily pass it through parameters in your method, that will avoid errors if ever the sender is of different types. But that won't be a problem in your case, as both senders are of type Button.

A simple way to find this out in Windows is to run SQLPlus from your Oracle homes's bin directory and then check Task Manager. If it is a 32-bit version of SQLPlus, you'll see a process on the Processes tab that looks like this:

sqlplus.exe *32

If it is 64-bit, the process will look like this:

sqlplus.exe

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

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

Close the modal box using javascript

$('#product-options').modal('hide');

Open the modal box using javascript

$('#product-options').modal('show');

Toggle the modal box using javascript

$('#myModal').modal('toggle');

Means close the modal if it's open and vice versa.

HTML5: Use the value attribute (no CSS needed)

Modern browsers will interpret the value attribute and will display it as you expect. See MDN documentation.

<ol>_x000D_
  <li value="3">This is item three.</li>_x000D_
  <li value="50">This is item fifty.</li>_x000D_
  <li value="100">This is item one hundred.</li>_x000D_
</ol>

Also have a look at the <ol> article on MDN, especially the documentation for the start and attribute.

FOR will give you any information you'll ever need to know about FOR loops, including examples on proper usage.

To print a vector which possibly has complex numbers-

fprintf('Answer: %s\n', sprintf('%d ', num2str(x)));

Coalesce will fold nulls into a default:

COALESCE (fieldName, '') <> ''

It should be

yadayada.val.split(/\n/)

you're passing in a literal string to the split command, not a regex.

For me, the next worked well:

I wrapped the header and the content on a div

<div class="main-wrapper">
    <div class="header">

    </div>
    <div class="content">

    </div>
</div>

I used this reference to fill the height with flexbox. The CSS goes like this:

.main-wrapper {
    display: flex;
    flex-direction: column;
    min-height: 100vh;
}
.header {
    flex: 1;
}
.content {
    flex: 1;
}

Below is the pagination logic as a function

function Pagination(pageEleArr, numOfEleToDisplayPerPage) {
    this.pageEleArr = pageEleArr;
    this.numOfEleToDisplayPerPage = numOfEleToDisplayPerPage;
    this.elementCount = this.pageEleArr.length;
    this.numOfPages = Math.ceil(this.elementCount / this.numOfEleToDisplayPerPage);
    const pageElementsArr = function (arr, eleDispCount) {
        const arrLen = arr.length;
        const noOfPages = Math.ceil(arrLen / eleDispCount);
        let pageArr = [];
        let perPageArr = [];
        let index = 0;
        let condition = 0;
        let remainingEleInArr = 0;

        for (let i = 0; i < noOfPages; i++) {

            if (i === 0) {
                index = 0;
                condition = eleDispCount;
            }
            for (let j = index; j < condition; j++) {
                perPageArr.push(arr[j]);
            }
            pageArr.push(perPageArr);
            if (i === 0) {
                remainingEleInArr = arrLen - perPageArr.length;
            } else {
                remainingEleInArr = remainingEleInArr - perPageArr.length;
            }

            if (remainingEleInArr > 0) {
                if (remainingEleInArr > eleDispCount) {
                    index = index + eleDispCount;
                    condition = condition + eleDispCount;
                } else {
                    index = index + perPageArr.length;
                    condition = condition + remainingEleInArr;
                }
            }
            perPageArr = [];
        }
        return pageArr;
    }
    this.display = function (pageNo) {
        if (pageNo > this.numOfPages || pageNo <= 0) {
            return -1;
        } else {
            console.log('Inside else loop in display method');
            console.log(pageElementsArr(this.pageEleArr, this.numOfEleToDisplayPerPage));
            console.log(pageElementsArr(this.pageEleArr, this.numOfEleToDisplayPerPage)[pageNo - 1]);
            return pageElementsArr(this.pageEleArr, this.numOfEleToDisplayPerPage)[pageNo - 1];
        }
    }
}

const p1 = new Pagination(['a', 'b', 'c', 'd', 'e', 'f', 'g'], 3);
console.log(p1.elementCount);
console.log(p1.pageEleArr);
console.log(p1.numOfPages);
console.log(p1.numOfEleToDisplayPerPage);
console.log(p1.display(3));

Make sure you have a jdk setup. To do this, create a new project and then go to file -> project structure. From there you can add a new jdk. Once that is setup, go back to your gradle project and you should have a jdk to select in the 'Gradle JVM' field.

Using jQuery

I would create a button and an invisible input like so:

<button id="button">Open</button>
<input id="file-input" type="file" name="name" style="display: none;" />

and add some jQuery to trigger it:

$('#button').on('click', function() {
    $('#file-input').trigger('click');
});

Using Vanilla JS

Same idea, without jQuery (credits to @Pascale):

<button onclick="document.getElementById('file-input').click();">Open</button>
<input id="file-input" type="file" name="name" style="display: none;" />

You will need to change JAVA_HOME path to the Java SDK directory instead of the Java RE directory. In Windows you can do this using the set command in a command prompt.

e.g.

set JAVA_HOME="C:\Program Files\Java\jdk1.6.0_14"

People like me who are looking for something like this in in build:

<script type="text/javascript" src="https://dsomething.cloudfront.net/static/js/main.ec7f8972.js">

Then setting https://dsomething.cloudfront.net to homepage in package.json will not work.

1. Quick Solution

Build your project like this:
(windows)

set PUBLIC_URL=https://dsomething.cloudfront.net&&npm run build

(linux/mac)

PUBLIC_URL=https://dsomething.cloudfront.net npm run build

And you will get

<script type="text/javascript" src="https://dsomething.cloudfront.net/static/js/main.ec7f8972.js">

in your built index.html

2. Permanent & Recommended Solution

Create a file called .env at your project root(same place where package.json is located).
In this file write this(no quotes around the url):

PUBLIC_URL=https://dsomething.cloudfront.net

Build your project as usual (npm run build)
This will also generate index.html with:

<script type="text/javascript" src="https://dsomething.cloudfront.net/static/js/main.ec7f8972.js">

3. Weird Solution (Will do not work in latest react-scripts version)

Add this in your package.json
"homepage": "http://://dsomething.cloudfront.net",

Then index.html will be generated with:

<script type="text/javascript" src="//dsomething.cloudfront.net/static/js/main.ec7f8972.js">

Which is basically the same as:

<script type="text/javascript" src="https://dsomething.cloudfront.net/static/js/main.ec7f8972.js">

in my understanding.

For some who wants to reset the form can also use type="reset" inside any form.

<form action="/action_page.php">

<input type="reset" value="Reset">
<input type="submit" value="Submit">

I do not use const for value-passed parametere. The caller does not care whether you modify the parameter or not, it's an implementation detail.

What is really important is to mark methods as const if they do not modify their instance. Do this as you go, because otherwise you might end up with either lots of const_cast<> or you might find that marking a method const requires changing a lot of code because it calls other methods which should have been marked const.

I also tend to mark local vars const if I do not need to modify them. I believe it makes the code easier to understand by making it easier to identify the "moving parts".

I don't know how it works, but you can also use it to tab your values !

Example :

Console.WriteLine($"I can tab like {"this !", 5}.");

Of course, you can replace "this !" with any variable or anything meaningful, just as you can also change the tab.
