Unless you resize up, you cannot do this with raster graphics.

What you can do with good filtering and smoothing is to resize without losing any noticable quality.

You can also alter the DPI metadata of the image (assuming it has some) which will keep exactly the same pixel count, but will alter how image editors think of it in 'real-world' measurements.

And just to cover all bases, if you really meant just the file size of the image and not the actual image dimensions, I suggest you look at a lossless encoding of the image data. My suggestion for this would be to resave the image as a .png file (I tend to use paint as a free transcoder for images in windows. Load image in paint, save as in the new format)

Only set the width or height, and it will scale the other automatically. And yes you can use a percentage.

The first part can be done, but requires JavaScript, so might not work for all users.

There's an article on Code Project about using GDI+ for .NET to do photo resizing using, say, Bicubic interpolation.

There was also another article about this topic on another blog (MS employee, I think), but I can't find the link anywhere. :( Perhaps someone else can find it?

Below code Working for scale image as aspect ratio:

Bitmap bitmapImage = BitmapFactory.decodeFile("Your path");
int nh = (int) ( bitmapImage.getHeight() * (512.0 / bitmapImage.getWidth()) );
Bitmap scaled = Bitmap.createScaledBitmap(bitmapImage, 512, nh, true);
your_imageview.setImageBitmap(scaled);

Just generalizing it down to aspect ratios and sizes, image stuff can be done outside of this function

public static d.RectangleF ScaleRect(d.RectangleF dest, d.RectangleF src, 
  bool keepWidth, bool keepHeight)  
{
    d.RectangleF destRect = new d.RectangleF();

    float sourceAspect = src.Width / src.Height;
    float destAspect = dest.Width / dest.Height;

    if (sourceAspect > destAspect)
    {
        // wider than high keep the width and scale the height
        destRect.Width = dest.Width;
        destRect.Height = dest.Width / sourceAspect;

        if (keepHeight)
        {
            float resizePerc = dest.Height / destRect.Height;
            destRect.Width = dest.Width * resizePerc;
            destRect.Height = dest.Height;
        }
    }
    else
    {
        // higher than wide – keep the height and scale the width
        destRect.Height = dest.Height;
        destRect.Width = dest.Height * sourceAspect;

        if (keepWidth)
        {
            float resizePerc = dest.Width / destRect.Width;
            destRect.Width = dest.Width;
            destRect.Height = dest.Height * resizePerc;
        }

    }

    return destRect;
}

As @Bozho says, you probably want to use getScaledInstance.

To understand how grph.scale(2.0, 2.0) works however, you could have a look at this code:

import java.awt.*;
import java.awt.image.BufferedImage;
import java.io.*;

import javax.imageio.ImageIO;
import javax.swing.ImageIcon;


class Main {
    public static void main(String[] args) throws IOException {

        final int SCALE = 2;

        Image img = new ImageIcon("duke.png").getImage();

        BufferedImage bi = new BufferedImage(SCALE * img.getWidth(null),
                                             SCALE * img.getHeight(null),
                                             BufferedImage.TYPE_INT_ARGB);

        Graphics2D grph = (Graphics2D) bi.getGraphics();
        grph.scale(SCALE, SCALE);

        // everything drawn with grph from now on will get scaled.

        grph.drawImage(img, 0, 0, null);
        grph.dispose();

        ImageIO.write(bi, "png", new File("duke_double_size.png"));
    }
}

Given duke.png:

it produces duke_double_size.png:

Please try this code:

$("#YourSelect>option:selected").html()

I work with Windows7.

Control Panel - Region and Language - Administrative - Language for non-Unicode programs.

After I set "Change system locale" to English(United States). My default encoding of vs2010 change to Windows-1252. It was gb2312 before.

I created a new .cpp file for a C++ project, after checking in the new file to TFS the encoding show Windows-1252 from the properties page of the file.

@RobW's answer is correct, but this is more performant ! Because it uses a hashmap/set:

const customStringify = function (v) {
  const cache = new Set();
  return JSON.stringify(v, function (key, value) {
    if (typeof value === 'object' && value !== null) {
      if (cache.has(value)) {
        // Circular reference found
        try {
          // If this value does not reference a parent it can be deduped
         return JSON.parse(JSON.stringify(value));
        }
        catch (err) {
          // discard key if value cannot be deduped
         return;
        }
      }
      // Store value in our set
      cache.add(value);
    }
    return value;
  });
};

For the rows containing strings, I can convert them to strings as in changing

tmpStr = nameItem("lastname") + " " + nameItem("initials")

to

tmpStr = myItem("lastname").toString + " " + myItem("intials").toString

For the comparison in the if statement myItem("sID")=sID, it needs to be change to

myItem("sID").Equals(sID)

Then the code will run without any runtime errors due to vbNull data.

You can use

Uri.EscapeUriString (see http://msdn.microsoft.com/en-us/library/system.uri.escapeuristring.aspx)

Both are synchronized version of HashMap, with difference in their core functionality and their internal structure.

ConcurrentHashMap consist of internal segments which can be viewed as independent HashMaps Conceptually. All such segments can be locked by separate threads in high concurrent executions. So, multiple threads can get/put key-value pairs from ConcurrentHashMap without blocking/waiting for each other. This is implemented for higher throughput.

whereas

Collections.synchronizedMap(), we get a synchronized version of HashMap and it is accessed in blocking manner. This means if multiple threads try to access synchronizedMap at same time, they will be allowed to get/put key-value pairs one at a time in synchronized manner.

What is wrong with Date.parse method?

str = "Tue, 10 Aug 2010 01:20:19 -0400 (EDT)"
date = Date.parse str
=> #<Date: 4910837/2,0,2299161>
puts date
2010-08-10

It seems to work.

The only problem here is time zone. If you want date in UTC time zone, then it is better to use Time object, suppose we have string:

str = "Tue, 10 Aug 2010 01:20:19 +0400"
puts Date.parse str
2010-08-10
puts Date.parse(Time.parse(str).utc.to_s)
2010-08-09

I couldn't find simpler method to convert Time to Date.

You have two options; either handle the exception or test the length:

if len(dlist) > 1:
    newlist.append(dlist[1])
    continue

or

try:
    newlist.append(dlist[1])
except IndexError:
    pass
continue

Use the first if there often is no second item, the second if there sometimes is no second item.

Don't know for sure, but it sounds like it is still submitting. I quick solution would be to change your (guessing at your code here):

<input type="submit" value="Submit" onclick="checkform()">

to a button:

<input type="button" value="Submit" onclick="checkform()">

That way your form still gets submitted (from the else part of your checkform()) and it shouldn't be reloading the page.

There are other, perhaps better, ways of handling it but this works in the mean time.

You can use this: document.getElementById('h1_id').innerHTML = 'the new text';

To answer the question. stringstream basically allows you to treat a string object like a stream, and use all stream functions and operators on it.

I saw it used mainly for the formatted output/input goodness.

One good example would be c++ implementation of converting number to stream object.

Possible example:

template <class T>
string num2str(const T& num, unsigned int prec = 12) {
    string ret;
    stringstream ss;
    ios_base::fmtflags ff = ss.flags();
    ff |= ios_base::floatfield;
    ff |= ios_base::fixed;
    ss.flags(ff);
    ss.precision(prec);
    ss << num;
    ret = ss.str();
    return ret;
};

Maybe it's a bit complicated but it is quite complex. You create stringstream object ss, modify its flags, put a number into it with operator<<, and extract it via str(). I guess that operator>> could be used.

Also in this example the string buffer is hidden and not used explicitly. But it would be too long of a post to write about every possible aspect and use-case.

Note: I probably stole it from someone on SO and refined, but I don't have original author noted.

You don't need a regex for this. Use tr:

"some text\nandsomemore".tr("\n","")

You could also enter the following into a CMD window:

dir <ParentDirectory> /X

Where <ParentDirectory> is replaced with the full path of the directory containing the item you would like the name for.

While the output is not a simple as Timbo's answer, it will list all the items in the specified directory with the actual name and (if different) the short name.

If you do use for %I in (.) do echo %~sI you can replace the . with the full path of the file/folder to get the short name of that file/folder (otherwise the short name of the current folder is returned).

Tested on Windows 7 x64.

Personally, I like setting the options directly with an assignment statement as it is easy to find via tab completion thanks to iPython. I find it hard to remember what the exact option names are, so this method works for me.

For instance, all I have to remember is that it begins with pd.options

pd.options.<TAB>

Most of the options are available under display

pd.options.display.<TAB>

From here, I usually output what the current value is like this:

pd.options.display.max_rows
60

I then set it to what I want it to be:

pd.options.display.max_rows = 100

Also, you should be aware of the context manager for options, which temporarily sets the options inside of a block of code. Pass in the option name as a string followed by the value you want it to be. You may pass in any number of options in the same line:

with pd.option_context('display.max_rows', 100, 'display.max_columns', 10):
    some pandas stuff

You can also reset an option back to its default value like this:

pd.reset_option('display.max_rows')

And reset all of them back:

pd.reset_option('all')

It is still perfectly good to set options via pd.set_option. I just find using the attributes directly is easier and there is less need for get_option and set_option.

If your end goal is to add elements to your page, just manipulate the DOM directly. Don't use string concatenation to try to create HTML - what a pain! See how much more straightforward it is to just create your element, instead of the HTML that represents your element:

var x = document.createElement("option");
x.value = col;
x.text = "Very roomy";
x.selected = col == "screwdriver";

Then, later when you put the element in your page, instead of setting the innerHTML of the parent element, call appendChild():

mySelectElement.appendChild(x);

This is what i usally use:

$x= array(1,2,3);
echo "<pre>".var_export($x,1)."</pre>";

https://github.com/cscott/jsshaper implements a translator from JavaScript 1.8 to ECMAScript 5.1, which would allow you to use 'for each' in code running on webkit or node.

Github blog spoke yesterday about Egit plugin:

http://freshmeat.net/projects/jgit/

The solution to this is actually easier than I thought. You can simply add in your custom adapter's getView() method a setOnClickListener() for the buttons you're using.

Any data associated with the button has to be added with myButton.setTag() in the getView() and can be accessed in the onClickListener via view.getTag()

I posted a detailed solution on my blog as a tutorial.

<?php
if (in_array('your_variable', $Your_array)) {
    $redImg = 'true code here';
} else {
    $redImg = 'false code here';
} 
?>

This could be simply done this way:

var dateOnly = new DateTime(dateTime.Year, dateTime.Month, dateTime.Day)

If you aren't using an auto-filter (i.e. you have manually hidden rows), you will need to use the AGGREGATE function instead of SUBTOTAL.

Additionally to the answer of @tkruse and @Yishai:
I do this way to conditionally skip test methods especially for Parameterized tests, if a test method should only run for some test data records.

public class MyTest {
    // get current test method
    @Rule public TestName testName = new TestName();
    
    @Before
    public void setUp() {
        org.junit.Assume.assumeTrue(new Function<String, Boolean>() {
          @Override
          public Boolean apply(String testMethod) {
            if (testMethod.startsWith("testMyMethod")) {
              return <some condition>;
            }
            return true;
          }
        }.apply(testName.getMethodName()));
        
        ... continue setup ...
    }
}

Use findElement instead of findElements

driver.findElement(By.xpath("//input[@id='invoice_supplier_id'])).sendKeys("your value");

OR

driver.findElement(By.id("invoice_supplier_id")).sendKeys("value", "your value");

OR using JavascriptExecutor

WebElement element = driver.findElement(By.xpath("enter the xpath here")); // you can use any locator
 JavascriptExecutor jse = (JavascriptExecutor)driver;
 jse.executeScript("arguments[0].value='enter the value here';", element);

OR

(JavascriptExecutor) driver.executeScript("document.evaluate(xpathExpresion, document, null, 9, null).singleNodeValue.innerHTML="+ DesiredText);

OR (in javascript)

driver.findElement(By.xpath("//input[@id='invoice_supplier_id'])).setAttribute("value", "your value")

Hope it will help you :)

The simplest way I found is it that includes host/path/query and

From Excel Macro Security - www.excelfunctions.net:

Macro Security in Excel 2007, 2010 & 2013:

.....

The different Excel file types provided by the latest versions of Excel make it clear when workbook contains macros, so this in itself is a useful security measure. However, Excel also has optional macro security settings, which are controlled via the options menu. These are :

'Disable all macros without notification'

• This setting does not allow any macros to run. When you open a new Excel workbook, you are not alerted to the fact that it contains macros, so you may not be aware that this is the reason a workbook does not work as expected.

'Disable all macros with notification'

• This setting prevents macros from running. However, if there are macros in a workbook, a pop-up is displayed, to warn you that the macros exist and have been disabled.

'Disable all macros except digitally signed macros'

• This setting only allow macros from trusted sources to run. All other macros do not run. When you open a new Excel workbook, you are not alerted to the fact that it contains macros, so you may not be aware that this is the reason a workbook does not work as expected.

'Enable all macros'

• This setting allows all macros to run. When you open a new Excel workbook, you are not alerted to the fact that it contains macros and may not be aware of macros running while you have the file open.

If you trust the macros and are ok with enabling them, select this option:

'Enable all macros'

and this dialog box should not show up for macros.

As for the dialog for saving, after noting that this was running on Excel for Mac 2011, I came across the following question on SO, StackOverflow - Suppress dialog when using VBA to save a macro containing Excel file (.xlsm) as a non macro containing file (.xlsx). From it, removing the dialog does not seem to be possible, except for possibly by some Keyboard Input simulation. I would post another question to inquire about that. Sorry I could only get you halfway. The other option would be to use a Windows computer with Microsoft Excel, though I'm not sure if that is a option for you in this case.

I think it has to do with your second element in storbinary. You are trying to open file, but it is already a pointer to the file you opened in line file = open(local_path,'rb'). So, try to use ftp.storbinary("STOR " + i, file).

I found this wonderful mapping script (mapper.js) that I have used in the past. What's different about it is you can hover over the map or a link on your page to make the map area highlight. Sadly it's written in javascript and requires a lot of in-line coding in the HTML - I would love to see this script ported over to jQuery :P

Also, check out all the demos! I think this example could almost be made into a simple online game (without using flash) - make sure you click on the different camera angles.

I have success with using the Chrome addon "Sharelatex". This online editor has great compability with most latex files, but it somewhat lacks configuration possibilities. www.sharelatex.com

I'm probably going a million miles in the wrong direct (but i'm only young :P ). but couldn't you add the graphic to a panel and then a mouselistener to the graphic object so that when the user on the graphic your action is preformed.

Button inputs don't have a submit event. Try attaching the event handler to the form instead:

<script type="text/javascript">
     $('#login_form').submit(function() {
       $('#gif').show(); 
       return true;
     });
 </script>

    while(start <= end){_x000D_
        mid = Math.floor((end + start)/2);_x000D_
        if(val <= arr[mid]){_x000D_
            if(val >= arr[mid-1]){_x000D_
                arr.splice(mid,0,val);_x000D_
                break;_x000D_
            }_x000D_
            end = mid-1;_x000D_
        }else{_x000D_
            if(val <= arr[mid+1]){_x000D_
                arr.splice(mid+1,0,val);_x000D_
                break;_x000D_
            }_x000D_
            start = mid+1;_x000D_
        }_x000D_
    }_x000D_
    return arr;_x000D_
}_x000D_

    5,   6,  14,  19, 23, 44,_x000D_

Using Java 8+ features we can write the code in few lines:

protected static Collection<Path> find(String fileName, String searchDirectory) throws IOException {
    try (Stream<Path> files = Files.walk(Paths.get(searchDirectory))) {
        return files
                .filter(f -> f.getFileName().toString().equals(fileName))
                .collect(Collectors.toList());

    }
}

Files.walk returns a Stream<Path> which is "walking the file tree rooted at" the given searchDirectory. To select the desired files only a filter is applied on the Stream files. It compares the file name of a Path with the given fileName.

Note that the documentation of Files.walk requires

This method must be used within a try-with-resources statement or similar control structure to ensure that the stream's open directories are closed promptly after the stream's operations have completed.

I'm using the try-resource-statement.

For advanced searches an alternative is to use a PathMatcher:

protected static Collection<Path> find(String searchDirectory, PathMatcher matcher) throws IOException {
    try (Stream<Path> files = Files.walk(Paths.get(searchDirectory))) {
        return files
                .filter(matcher::matches)
                .collect(Collectors.toList());

    }
}

An example how to use it to find a certain file:

public static void main(String[] args) throws IOException {
    String searchDirectory = args[0];
    String fileName = args[1];
    PathMatcher matcher = FileSystems.getDefault().getPathMatcher("regex:.*" + fileName);
    Collection<Path> find = find(searchDirectory, matcher);
    System.out.println(find);
}

More about it: Oracle Finding Files tutorial

The real problem is that you are using dynamic return type in the FacebookClient Get method. And although you use a method for serializing, the JSON converter cannot deserialize this Object after that.

Use insted of:

dynamic result = client.Get("fql", new { q = "select target_id,target_type from connection where source_id = me()"}); 
string jsonstring = JsonConvert.SerializeObject(result);

something like that:

string result = client.Get("fql", new { q = "select target_id,target_type from connection where source_id = me()"}).ToString();

Then you can use DeserializeObject method:

var datalist = JsonConvert.DeserializeObject<List<RootObject>>(result);

Hope this helps.

Have you tried overflow-y:auto ? It is not exactly what you want, as the scrollbar will appear only when needed.

Goto SolutionExplorer (should be already visible, if not use menu: View->SolutionExplorer).

Find your .cxx file in the solution tree, right click on it and choose "Properties" from the popup menu. You will get window with your file's properties.

Using tree on the left side go to the "C++/Precompiled Headers" section. On the right side of the window you'll get three properties. Set property named "Create/Use Precompiled Header" to the value of "Not Using Precompiled Headers".

Make a connection and open it.

con = new OracleConnection("Data Source=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=localhost)(PORT=1521)))(CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=<database_name>)));User Id =<userid>; Password =<password>");
con.Open();

Write the select query:

string sql = "select * from Pending_Tasks";

Create a command object:

OracleCommand cmd = new OracleCommand(sql, con);

Execute the command and put the result in a object to read it.

OracleDataReader r = cmd.ExecuteReader();

now start reading from it.

while (read.Read())
{
 CustID.Text = (read["Customer_ID"].ToString());
 CustName.Text = (read["Customer_Name"].ToString());
 Add1.Text = (read["Address_1"].ToString());
 Add2.Text = (read["Address_2"].ToString());
 PostBox.Text = (read["Postcode"].ToString());
 PassBox.Text = (read["Password"].ToString());
 DatBox.Text = (read["Data_Important"].ToString());
 LanNumb.Text = (read["Landline"].ToString());
 MobNumber.Text = (read["Mobile"].ToString());
 FaultRep.Text = (read["Fault_Report"].ToString());
}
read.Close();

Add this too using Oracle.ManagedDataAccess.Client;

I had a similar problem and found the way that worked best was to rely on Event Bubbling and event delegation to handle it. The nice thing about event delegation is that once setup, you don't have to rebind events after an AJAX update.

What I do in my code is setup a delegate on the parent element of the update panel. This parent element is not replaced on an update and therefore the event binding is unaffected.

There are a number of good articles and plugins to handle event delegation in jQuery and the feature will likely be baked into the 1.3 release. The article/plugin I use for reference is:

http://www.danwebb.net/2008/2/8/event-delegation-made-easy-in-jquery

Once you understand what it happening, I think you'll find this a much more elegant solution that is more reliable than remembering to re-bind events after every update. This also has the added benefit of giving you one event to unbind when the page is unloaded.

The following code worked for me:

echo userInput

You can define a boolean and change it to false when you want to stop handler. Like this..

boolean stop = false;

handler.postDelayed(new Runnable() {
    @Override
    public void run() {

        //do your work here..

        if (!stop) {
            handler.postDelayed(this, delay);
        }
    }
}, delay);

I haven't done time test with this but it was fun to try. Basically convert two columns to one column of tuples. Now convert that to a dataframe, do 'value_counts()' which finds the unique elements and counts them. Fiddle with zip again and put the columns in order you want. You can probably make the steps more elegant but working with tuples seems more natural to me for this problem

b = pd.DataFrame({'A':['yes','yes','yes','yes','no','no','yes','yes','yes','no'],'B':['yes','no','no','no','yes','yes','no','yes','yes','no']})

b['count'] = pd.Series(zip(*[b.A,b.B]))
df = pd.DataFrame(b['count'].value_counts().reset_index())
df['A'], df['B'] = zip(*df['index'])
df = df.drop(columns='index')[['A','B','count']]

[For a bonus point...]

Using the JOIN syntax allows you to more easily comment out the join as its all included on one line. This can be useful if you are debugging a complex query

As everyone else says, they are functionally the same, however the JOIN is more clear of a statement of intent. It therefore may help the query optimiser either in current oracle versions in certain cases (I have no idea if it does), it may help the query optimiser in future versions of Oracle (no-one has any idea), or it may help if you change database supplier.

I have a similar scenario, and had no problem connecting after setting the JNLP port as you describe, and adding a single firewall rule allowing a connection on the server using that port. Granted it is a randomly selected client port going to a known server port (a host:ANY -> server:1 rule is needed).

From my reading of the source code, I don't see a way to set the local port to use when making the request from the slave. It's unfortunate, it would be a nice feature to have.

Alternatives:

Use a simple proxy on your client that listens on port N and then does forward all data to the actual Jenkins server on the remote host using a constant local port. Connect your slave to this local proxy instead of the real Jenkins server.

Create a custom Jenkins slave build that allows an option to specify the local port to use.

Remember also if you are using HTTPS via a self-signed certificate, you must alter the configuration jenkins-slave.xml file on the slave to specify the -noCertificateCheck option on the command line.

Make the value a list, e.g.

a["abc"] = [1, 2, "bob"]

UPDATE:

There are a couple of ways to add values to key, and to create a list if one isn't already there. I'll show one such method in little steps.

key = "somekey"
a.setdefault(key, [])
a[key].append(1)

Results:

>>> a
{'somekey': [1]}

Next, try:

key = "somekey"
a.setdefault(key, [])
a[key].append(2)

Results:

>>> a
{'somekey': [1, 2]}

The magic of setdefault is that it initializes the value for that key if that key is not defined, otherwise it does nothing. Now, noting that setdefault returns the key you can combine these into a single line:

a.setdefault("somekey",[]).append("bob")

Results:

>>> a
{'somekey': [1, 2, 'bob']}

You should look at the dict methods, in particular the get() method, and do some experiments to get comfortable with this.

Here's a tutorial about ordering objects:

• The Java Tutorials - Collections - Object Ordering

Although I will give some examples, I would recommend to read it anyway.

There are various way to sort an ArrayList. If you want to define a natural (default) ordering, then you need to let Contact implement Comparable. Assuming that you want to sort by default on name, then do (nullchecks omitted for simplicity):

public class Contact implements Comparable<Contact> {

    private String name;
    private String phone;
    private Address address;

    @Override
    public int compareTo(Contact other) {
        return name.compareTo(other.name);
    }

    // Add/generate getters/setters and other boilerplate.
}

so that you can just do

List<Contact> contacts = new ArrayList<Contact>();
// Fill it.

Collections.sort(contacts);

If you want to define an external controllable ordering (which overrides the natural ordering), then you need to create a Comparator:

List<Contact> contacts = new ArrayList<Contact>();
// Fill it.

// Now sort by address instead of name (default).
Collections.sort(contacts, new Comparator<Contact>() {
    public int compare(Contact one, Contact other) {
        return one.getAddress().compareTo(other.getAddress());
    }
}); 

You can even define the Comparators in the Contact itself so that you can reuse them instead of recreating them everytime:

public class Contact {

    private String name;
    private String phone;
    private Address address;

    // ...

    public static Comparator<Contact> COMPARE_BY_PHONE = new Comparator<Contact>() {
        public int compare(Contact one, Contact other) {
            return one.phone.compareTo(other.phone);
        }
    };

    public static Comparator<Contact> COMPARE_BY_ADDRESS = new Comparator<Contact>() {
        public int compare(Contact one, Contact other) {
            return one.address.compareTo(other.address);
        }
    };

}

which can be used as follows:

List<Contact> contacts = new ArrayList<Contact>();
// Fill it.

// Sort by address.
Collections.sort(contacts, Contact.COMPARE_BY_ADDRESS);

// Sort later by phone.
Collections.sort(contacts, Contact.COMPARE_BY_PHONE);

And to cream the top off, you could consider to use a generic javabean comparator:

public class BeanComparator implements Comparator<Object> {

    private String getter;

    public BeanComparator(String field) {
        this.getter = "get" + field.substring(0, 1).toUpperCase() + field.substring(1);
    }

    public int compare(Object o1, Object o2) {
        try {
            if (o1 != null && o2 != null) {
                o1 = o1.getClass().getMethod(getter, new Class[0]).invoke(o1, new Object[0]);
                o2 = o2.getClass().getMethod(getter, new Class[0]).invoke(o2, new Object[0]);
            }
        } catch (Exception e) {
            // If this exception occurs, then it is usually a fault of the developer.
            throw new RuntimeException("Cannot compare " + o1 + " with " + o2 + " on " + getter, e);
        }

        return (o1 == null) ? -1 : ((o2 == null) ? 1 : ((Comparable<Object>) o1).compareTo(o2));
    }

}

which you can use as follows:

// Sort on "phone" field of the Contact bean.
Collections.sort(contacts, new BeanComparator("phone"));

(as you see in the code, possibly null fields are already covered to avoid NPE's during sort)

import java.lang.String;

This is an unnecessary import. java.lang classes are always implicitly imported. This means that you do not have to import them manually (explicitly).

Just an addition to abeing's answer above. You can define a function to encapsulate the complexity of defineProperty as mentioned below.

var defineProp = function ( obj, key, value ){
  var config = {
    value: value,
    writable: true,
    enumerable: true,
    configurable: true
  };
  Object.defineProperty( obj, key, config );
};

//Call the method to add properties to any object
defineProp( data, "PropertyA",  1 );
defineProp( data, "PropertyB",  2 );
defineProp( data, "PropertyC",  3 );

Here is what worked for me: (I got this answer from https://productforums.google.com/forum/#!topic/chrome/MJjuK65Exkg)

1. Unpin Chrome icon from task bar so it is on the desktop.
2. Right mouse click on said icon and left click on Properties.
3. Click on Shortcuts tab 4A. In Target window, add this exact text: [space]--disable-gpu" 4B. The end of the text string in the Target window should now read: ...chrome.exe" --disable-gpu"
4. Double click on the desktop icon and Chrome should open correctly. If you want, you may pin this icon to the taskbar.
5. Left single click on the "Customize" icon in the top right, which is the 3 horizontal lines icon. Select "Settings" from the list.
6. Select "Show advanced settings..." at the bottom.
7. Deselect "Use hardware acceleration when available."

I think you can get it using subc1.text.

Or if you want to explore it, you can use .contents :

>>> p = soup.find('p')
>>> from pprint import pprint
>>> pprint(p.contents)

and filter out the necessary items from the list:

The current recommended way is with the flask command line utility.

https://flask.palletsprojects.com/en/1.1.x/quickstart/#debug-mode

Example:

$ export FLASK_APP=main.py
$ export FLASK_ENV=development
$ flask run

or in one command:

$ FLASK_APP=main.py FLASK_ENV=development flask run

If you want different port than the default (5000) add --port option.

Example:

$ FLASK_APP=main.py FLASK_ENV=development flask run --port 8080

More options are available with:

$ flask run --help

FLASK_APP can also be set to module:app or module:create_app instead of module.py. See https://flask.palletsprojects.com/en/1.1.x/cli/#application-discovery for a full explanation.

The code starts file search from root colon, If I want to start search from a specific directory, to avoid going to that directory every time, where I should put one. I did it like

Sub GetFilePath()
FileSelected = "G:\Audits\A2010"
Set myFile = Application.FileDialog(msoFileDialogOpen)
With myFile
.Title = "Choose File"
.AllowMultiSelect = False
If .Show <> -1 Then
Exit Sub
End If
FileSelected = .SelectedItems(1)
End With

ActiveSheet.Range("C14") = FileSelected
End Sub

But it could not start reach from "G:\Audits\A2010"

For current ActiveRecord (4.2.4+) there is a method to_hash on the Result object that returns an array of hashes. You can then map over it and convert to symbolized hashes:

# Get an array of hashes representing the result (column => value):
result.to_hash
# => [{"id" => 1, "title" => "title_1", "body" => "body_1"},
      {"id" => 2, "title" => "title_2", "body" => "body_2"},
      ...
     ]

result.to_hash.map(&:symbolize_keys)
# => [{:id => 1, :title => "title_1", :body => "body_1"},
      {:id => 2, :title => "title_2", :body => "body_2"},
      ...
     ]

See the ActiveRecord::Result docs for more info.

Object properties can be checked for existence by property_exists

Example from a unit test:

function testPropertiesExist()
{
    $sl =& $this->system_log;
    $props = array('log_id',
                   'type',
                   'message',
                   'username',
                   'ip_address',
                   'date_added');

    foreach($props as $prop) {
        $this->assertTrue(property_exists($sl, $prop),
                           "Property <{$prop}> exists");
    }
}

Underscore Mixins

Extending on @emil_lundberg's answer, you can also write a "mixin" if you're using Underscore to make a custom function for sorting if it's a kind of sorting you might repeat in an application somewhere.

For example, maybe you have a controller or view sorting results with sort order of "ASC" or "DESC", and you want to toggle between that sort, you could do something like this:

Mixin.js

_.mixin({
    sortByOrder: function(stooges, prop, order) {
      if (String(order) === "desc") {
          return _.sortBy(stooges, prop).reverse();
      } else if (String(order) === "asc") {
          return _.sortBy(stooges, prop);
      } else {
          return stooges;
      }
    }
})

Usage Example

var sort_order = "asc";
var stooges = [
  {name: 'moe', age: 40}, 
  {name: 'larry', age: 50}, 
  {name: 'curly', age: 60},
  {name: 'July', age: 35},
  {name: 'mel', age: 38}
 ];

_.mixin({
    sortByOrder: function(stooges, prop, order) {
    if (String(order) === "desc") {
        return _.sortBy(stooges, prop).reverse();
    } else if (String(order) === "asc") {
        return _.sortBy(stooges, prop);
    } else {
        return stooges;
    }
  }
})


// find elements
var banner = $("#banner-message");
var sort_name_btn = $("button.sort-name");
var sort_age_btn = $("button.sort-age");

function showSortedResults(results, sort_order, prop) {
    banner.empty();
    banner.append("<p>Sorting: " + prop + ', ' + sort_order + "</p><hr>")
  _.each(results, function(r) {
    banner.append('<li>' + r.name + ' is '+ r.age + ' years old.</li>');
  }) 
}

// handle click and add class
sort_name_btn.on("click", function() {
  sort_order = (sort_order === "asc") ? "desc" : "asc"; 
    var sortedResults = _.sortByOrder(stooges, 'name', sort_order);
  showSortedResults(sortedResults, sort_order, 'name');
})

sort_age_btn.on('click', function() {
    sort_order = (sort_order === "asc") ? "desc" : "asc"; 
    var sortedResults = _.sortByOrder(stooges, 'age', sort_order);
  showSortedResults(sortedResults, sort_order, 'age');
})

Here's a JSFiddle demonstrating this: JSFiddle for SortBy Mixin

If your computer can't find the IP address associated with SUBDOMAIN1.example.COM, it will not find the site.

You need to either change your hosts file (so you can at least test things - this will be a local change, only available to yourself), or update DNS so the name will resolve correctly (so the rest of the world can see it).

Do not create separate lists; create a list of lists:

results = []
with open('inputfile.txt') as inputfile:
    for line in inputfile:
        results.append(line.strip().split(','))

or better still, use the csv module:

import csv

results = []
with open('inputfile.txt', newline='') as inputfile:
    for row in csv.reader(inputfile):
        results.append(row)

Lists or dictionaries are far superiour structures to keep track of an arbitrary number of things read from a file.

Note that either loop also lets you address the rows of data individually without having to read all the contents of the file into memory either; instead of using results.append() just process that line right there.

Just for completeness sake, here's the one-liner compact version to read in a CSV file into a list in one go:

import csv

with open('inputfile.txt', newline='') as inputfile:
    results = list(csv.reader(inputfile))

I just wanted to answer something new for this question - J2V8.

Author Ian Bull says "Rhino and Nashorn are two common JavaScript runtimes, but these did not meet our requirements in a number of areas:

Neither support ‘Primitives‘. All interactions with these platforms require wrapper classes such as Integer, Double or Boolean. Nashorn is not supported on Android. Rhino compiler optimizations are not supported on Android. Neither engines support remote debugging on Android.""

Highly Efficient Java & JavaScript Integration

One possible workaround would be using a "frame-breaker" script as described here

You just need to alter the "if" statement to check for your allowed domains.

   if (self === top) {
       var antiClickjack = document.getElementById("antiClickjack");
       antiClickjack.parentNode.removeChild(antiClickjack);
   } else {
       //your domain check goes here
       if(top.location.host != "allowed.domain1.com" && top.location.host == "allowed.domain2.com")
         top.location = self.location;
   }

This workaround would be safe, I think. because with javascript not enabled you will have no security concern about a malicious website framing your page.

Use the entity code   instead.

  is a HTML "character entity reference". There is no named entity for non-breaking space in XML, so you use the code  .

Wikipedia includes a list of XML and HTML entities, and you can see that there are only 5 "predefined entities" in XML, but HTML has over 200. I'll also point over to Creating a space ( ) in XSL which has excellent answers.

According to this message on the GCC mailing list, you can use the file "nul" instead of /dev/null:

#include <stdio.h>

int main ()
{
    FILE* outfile = fopen ("/dev/null", "w");
    if (outfile == NULL)
    {
        fputs ("could not open '/dev/null'", stderr);
    }
    outfile = fopen ("nul", "w");
    if (outfile == NULL)
    {
        fputs ("could not open 'nul'", stderr);
    }

    return 0;
}

(Credits to Danny for this code; copy-pasted from his message.)

You can also use this special "nul" file through redirection.

Use npm install angular-cli --save-dev

Here's another solution using df.transform and df.set_index:

>>> (df['teams']
       .transform([lambda x:x[0], lambda x:x[1]])
       .set_axis(['team1','team2'],
                  axis=1,
                  inplace=False)
    )

  team1 team2
0    SF   NYG
1    SF   NYG
2    SF   NYG
3    SF   NYG
4    SF   NYG
5    SF   NYG
6    SF   NYG

You could use JavaScript and trigger the hidden file input when the button input has been clicked.

http://jsfiddle.net/gregorypratt/dhyzV/ - simple

http://jsfiddle.net/gregorypratt/dhyzV/1/ - fancier with a little JQuery

Or, you could style a div directly over the file input and set pointer-events in CSS to none to allow the click events to pass through to the file input that is "behind" the fancy div. This only works in certain browsers though; http://caniuse.com/pointer-events

Both 'is' and 'as' are valid syntax. Output is disabled by default. Try a procedure that also enables output...

create or replace procedure temp_proc is
begin
  DBMS_OUTPUT.ENABLE(1000000);
  DBMS_OUTPUT.PUT_LINE('Test');
end;

...and call it in a PLSQL block...

begin
  temp_proc;
end;

...as SQL is non-procedural.

 <?php
$array["a"] = "Thusitha";
$array["b"] = "Sumanadasa";
$array["c"] = "Lakmal";
$array["d"] = "Nanayakkara";

$str = serialize($array);
$strenc = urlencode($str);
print $str . "\n";
print $strenc . "\n";
?> 

print $str . "\n"; gives a:4:{s:1:"a";s:8:"Thusitha";s:1:"b";s:10:"Sumanadasa";s:1:"c";s:6:"Lakmal";s:1:"d";s:11:"Nanayakkara";} and

print $strenc . "\n"; gives

a%3A4%3A%7Bs%3A1%3A%22a%22%3Bs%3A8%3A%22Thusitha%22%3Bs%3A1%3A%22b%22%3Bs%3A10%3A%22Sumanadasa%22%3Bs%3A1%3A%22c%22%3Bs%3A6%3A%22Lakmal%22%3Bs%3A1%3A%22d%22%3Bs%3A11%3A%22Nanayakkara%22%3B%7D

So if you want to pass this $array through URL to page_no_2.php,

ex:-

$url ='http://page_no_2.php?data=".$strenc."';

To return back to the original array, it needs to be urldecode(), then unserialize(), like this in page_no_2.php:

    <?php
    $strenc2= $_GET['data'];
    $arr = unserialize(urldecode($strenc2));
    var_dump($arr);
    ?>

gives

 array(4) {
  ["a"]=>
  string(8) "Thusitha"
  ["b"]=>
  string(10) "Sumanadasa"
  ["c"]=>
  string(6) "Lakmal"
  ["d"]=>
  string(11) "Nanayakkara"
}

Use XmlDocument.Load() method to load XML from your file. Then use XmlDocument.InnerXml property to get XML string.

XmlDocument doc = new XmlDocument();
doc.Load("path to your file");
string xmlcontents = doc.InnerXml;

In addition to the accepted answer, it is useful to know the following ...

Each of those functions should have manual pages associated with them.

If you run man -k syslog (a keyword search of man pages) you will get a list of man pages that refer to, or are about syslog

$ man -k syslog
logger (1)           - a shell command interface to the syslog(3) system l...
rsyslog.conf (5)     - rsyslogd(8) configuration file
rsyslogd (8)         - reliable and extended syslogd

syslog (3)           - send messages to the system logger
vsyslog (3)          - send messages to the system logger

You need to understand the manual sections in order to delve further.

Here's an excerpt from the man page for man, that explains man page sections :

The table below shows the section numbers of the manual followed  by
the types of pages they contain.

   1   Executable programs or shell commands
   2   System calls (functions provided by the kernel)
   3   Library calls (functions within program libraries)
   4   Special files (usually found in /dev)
   5   File formats and conventions eg /etc/passwd
   6   Games
   7   Miscellaneous  (including  macro  packages and conven-
       tions), e.g. man(7), groff(7)
   8   System administration commands (usually only for root)
   9   Kernel routines [Non standard]

To read the above run

$man man 

So, if you run man 3 syslog you get a full manual page for the syslog function that you called in your code.

SYSLOG(3)                Linux Programmer's Manual                SYSLOG(3)

   void vsyslog(int priority, const char *format, va_list ap);

Not a direct answer but hopefully you will find this useful.

You don't need to define intersection. It's already a first-class part of set.

>>> b1 = [1,2,3,4,5,9,11,15]
>>> b2 = [4,5,6,7,8]
>>> set(b1).intersection(b2)
set([4, 5])

        console.log(response);
      });//

This is more an object initialzation question more than a jpa question, both methods work and you can have both of them at the same time , usually if the data member value is ready before the instantiation you use the constructor parameters, if this value could be updated after the instantiation you should have a setter.

Such a silly solution in my case:

// Example a
#include <iostream>    
#include "stdafx.h"

The above was odered as per example a, when I changed it to resemble example b below...

// Example b
#include "stdafx.h"
#include <iostream>  

My code compiled like a charm. Try it, guaranteed to work.

ApplicationContext applicationContext = new ClassPathXmlApplicationContext("/spring-servlet.xml");

Then you can retrieve the bean:

MyClass myClass = (MyClass) context.getBean("myClass");

Transaction - is just a logically composed set of operations you want all together be either committed or rolled back.

I'm going to throw my two cents into this question and suggest a slightly more verbose extension of elias's answer. As of gcc 4.6, running of gcc -march=native -v -E - < /dev/null emits an increasing amount of spam in the form of superfluous -mno-* flags. The following will strip these:

gcc -march=native -v -E - < /dev/null 2>&1 | grep cc1 | perl -pe 's/ -mno-\S+//g; s/^.* - //g;'

However, I have only verified the correctness of this on two different CPUs (an Intel Core2 and AMD Phenom), so I suggest also running the following script to be sure that all of these -mno-* flags can be safely stripped.

2021 EDIT: There are indeed machines where -march=native uses a particular -march value, but must disable some implied ISAs (Instruction Set Architecture) with -mno-*.

#!/bin/bash

gcc_cmd="gcc"

# Optionally supply path to gcc as first argument
if (($#)); then
    gcc_cmd="$1"
fi

with_mno=$(
    "${gcc_cmd}" -march=native -mtune=native -v -E - < /dev/null 2>&1 |
    grep cc1 |
    perl -pe 's/^.* - //g;'
)
without_mno=$(echo "${with_mno}" | perl -pe 's/ -mno-\S+//g;')

"${gcc_cmd}" ${with_mno}    -dM -E - < /dev/null > /tmp/gcctest.a.$$
"${gcc_cmd}" ${without_mno} -dM -E - < /dev/null > /tmp/gcctest.b.$$

if diff -u /tmp/gcctest.{a,b}.$$; then
    echo "Safe to strip -mno-* options."
else
    echo
    echo "WARNING! Some -mno-* options are needed!"
    exit 1
fi

rm /tmp/gcctest.{a,b}.$$

I haven't found a difference between gcc -march=native -v -E - < /dev/null and gcc -march=native -### -E - < /dev/null other than some parameters being quoted -- and parameters that contain no special characters, so I'm not sure under what circumstances this makes any real difference.

Finally, note that --march=native was introduced in gcc 4.2, prior to which it is just an unrecognized argument.

Intention of ConstraintLayout is to optimize and flatten the view hierarchy of your layouts by applying some rules to each view to avoid nesting.

Rules remind you of RelativeLayout, for example setting the left to the left of some other view.

app:layout_constraintBottom_toBottomOf="@+id/view1"

Unlike RelativeLayout, ConstraintLayout offers bias value that is used to position a view in terms of 0% and 100% horizontal and vertical offset relative to the handles (marked with circle). These percentages (and fractions) offer seamless positioning of the view across different screen densities and sizes.

app:layout_constraintHorizontal_bias="0.33" <!-- from 0.0 to 1.0 -->
app:layout_constraintVertical_bias="0.53" <!-- from 0.0 to 1.0 -->

Baseline handle (long pipe with rounded corners, below the circle handle) is used to align content of the view with another view reference.

Square handles (on each corner of the view) are used to resize the view in dps.

This is totally opinion based and my impression of ConstraintLayout

the right way(!) to do it is to

1. fork()
2. setsid()
3. execve()

fork forks, setsid tell the current process to become a master one (no parent), execve tell the calling process to be replaced by the called one. so that the parent can quit without affecting the child.

 $pid=pcntl_fork();
 if($pid==0)
 {
   posix_setsid();
   pcntl_exec($cmd,$args,$_ENV);
   // child becomes the standalone detached process
 }

 // parent's stuff
 exit();

This function provided by Nick is good but if you use new String(byte[] bytes) to make the transformation to String, it failed. You can use this function to do that.

private static final char[] hex = { '0', '1', '2', '3', '4', '5', '6', '7', '8', '9', 'a', 'b', 'c', 'd', 'e', 'f' };

public static String byteArray2Hex(byte[] bytes) {
    StringBuffer sb = new StringBuffer(bytes.length * 2);
    for(final byte b : bytes) {
        sb.append(hex[(b & 0xF0) >> 4]);
        sb.append(hex[b & 0x0F]);
    }
    return sb.toString();
}

public static String getStringFromSHA256(String stringToEncrypt) throws NoSuchAlgorithmException {
    MessageDigest messageDigest = MessageDigest.getInstance("SHA-256");
    messageDigest.update(stringToEncrypt.getBytes());
    return byteArray2Hex(messageDigest.digest());
}

May be this can help somebody

I really liked @Daniel's answer, but the console.log{color} functions didn't work the same way as regular console.log. I have made a few changes, and now all parameters to the new functions will be passed to console.log (as well as the color codes).

const _colors = {
    Reset : "\x1b[0m",
    Bright : "\x1b[1m",
    Dim : "\x1b[2m",
    Underscore : "\x1b[4m",
    Blink : "\x1b[5m",
    Reverse : "\x1b[7m",
    Hidden : "\x1b[8m",

    FgBlack : "\x1b[30m",
    FgRed : "\x1b[31m",
    FgGreen : "\x1b[32m",
    FgYellow : "\x1b[33m",
    FgBlue : "\x1b[34m",
    FgMagenta : "\x1b[35m",
    FgCyan : "\x1b[36m",
    FgWhite : "\x1b[37m",

    BgBlack : "\x1b[40m",
    BgRed : "\x1b[41m",
    BgGreen : "\x1b[42m",
    BgYellow : "\x1b[43m",
    BgBlue : "\x1b[44m",
    BgMagenta : "\x1b[45m",
    BgCyan : "\x1b[46m",
    BgWhite : "\x1b[47m",
};

const enableColorLogging = function(){
    Object.keys(_colors).forEach(key => {
        console['log' + key] = function(){
            return console.log(_colors[key], ...arguments, _colors.Reset);
        }
    });
}

If you want to remove the routes cache on your server, remove this file:

bootstrap/cache/routes.php

And if you want to update it just run php artisan route:cache and upload the bootstrap/cache/routes.php to your server.

Check file permissions of the /var/www/html and the ALLOW directive in your apache conf

Make sure all files are readable by the webserver and the allow directive is like

 <Directory "/var/www/html">
    Order allow,deny
    Allow from all
  </Directory>

if you can see files then consider sorting the directive to be more restrictive

The problem is with line

imageWidth = 1 * Convert.ToInt32(Label1.Text);

Label1.Text may or may not be int. Check.

Use Int32.TryParse(value, out number) instead. That will solve your problem.

int imageWidth;
if(Int32.TryParse(Label1.Text, out imageWidth))
{
    Image1.Width= imageWidth;
}

Yes, Daniel is correct, but to expand upon his answer, your primary app component would need to have a navbar component within it. That way, when you render the primary app (any page under the '/' path), it would also display the navbar. I am guessing that you wouldn't want your login page to display the navbar, so that shouldn't be a nested component, and should instead be by itself. So your routes would end up looking something like this:

<Router>
  <Route path="/" component={App}>
    <Route path="page1" component={Page1} />
    <Route path="page2" component={Page2} />
  </Route>
  <Route path="/login" component={Login} />
</Router>

And the other components would look something like this:

var NavBar = React.createClass({
  render() {
    return (
      <div>
        <ul>
          <a onClick={() => history.push('page1') }>Page 1</a>
          <a onClick={() => history.push('page2') }>Page 2</a>
        </ul>
      </div>
    )
  }
});

var App = React.createClass({
  render() {
    return (
      <div>
        <NavBar />
        <div>Other Content</div>
        {this.props.children}
      </div>
    )
  }
});

Ideally you shouldn't be splitting strings in T-SQL at all.

Barring that change, on older versions before SQL Server 2016, create a split function:

CREATE FUNCTION dbo.SplitStrings
(
    @List      nvarchar(max), 
    @Delimiter nvarchar(2)
)
RETURNS TABLE
WITH SCHEMABINDING
AS
  RETURN ( WITH x(x) AS
    (
      SELECT CONVERT(xml, N'<root><i>' 
        + REPLACE(@List, @Delimiter, N'</i><i>') 
        + N'</i></root>')
    )
    SELECT Item = LTRIM(RTRIM(i.i.value(N'.',N'nvarchar(max)')))
      FROM x CROSS APPLY x.nodes(N'//root/i') AS i(i)
  );
GO

Now you can say:

DECLARE @Values varchar(1000);

SET @Values = 'A, B, C';

SELECT blah
  FROM dbo.foo
  INNER JOIN dbo.SplitStrings(@Values, ',') AS s
    ON s.Item = foo.myField;

On SQL Server 2016 or above (or Azure SQL Database), it is much simpler and more efficient, however you do have to manually apply LTRIM() to take away any leading spaces:

DECLARE @Values varchar(1000) = 'A, B, C';

SELECT blah
  FROM dbo.foo
  INNER JOIN STRING_SPLIT(@Values, ',') AS s
    ON LTRIM(s.value) = foo.myField;

git log -1 --format="%an %ae%n%cn %ce" a2c25061

The Pretty Formats section of the git show documentation contains

• format:<string>

The format:<string> format allows you to specify which information you want to show. It works a little bit like printf format, with the notable exception that you get a newline with %n instead of \n …

The placeholders are:

• %an: author name
• %ae: author email
• %cn: committer name
• %ce: committer email

You have set the upstream of that branch

(see:

• "How do you make an existing git branch track a remote branch?" and
• "Git: Why do I need to do --set-upstream-to all the time?"
  )

git branch -f --track my_local_branch origin/my_remote_branch
# OR (if my_local_branch is currently checked out):
$ git branch --set-upstream-to my_local_branch origin/my_remote_branch

(git branch -f --track won't work if the branch is checked out: use the second command git branch --set-upstream-to instead, or you would get "fatal: Cannot force update the current branch.")

That means your branch is already configured with:

branch.my_local_branch.remote origin
branch.my_local_branch.merge my_remote_branch

Git already has all the necessary information.
In that case:

# if you weren't already on my_local_branch branch:
git checkout my_local_branch 
# then:
git pull

is enough.

If you hadn't establish that upstream branch relationship when it came to push your 'my_local_branch', then a simple git push -u origin my_local_branch:my_remote_branch would have been enough to push and set the upstream branch.
After that, for the subsequent pulls/pushes, git pull or git push would, again, have been enough.

• The first danger lies in reload(sys).

  When you reload a module, you actually get two copies of the module in your runtime. The old module is a Python object like everything else, and stays alive as long as there are references to it. So, half of the objects will be pointing to the old module, and half to the new one. When you make some change, you will never see it coming when some random object doesn't see the change:

  (This is IPython shell)
  
  In [1]: import sys
  
  In [2]: sys.stdout
  Out[2]: <colorama.ansitowin32.StreamWrapper at 0x3a2aac8>
  
  In [3]: reload(sys)
  <module 'sys' (built-in)>
  
  In [4]: sys.stdout
  Out[4]: <open file '<stdout>', mode 'w' at 0x00000000022E20C0>
  
  In [11]: import IPython.terminal
  
  In [14]: IPython.terminal.interactiveshell.sys.stdout
  Out[14]: <colorama.ansitowin32.StreamWrapper at 0x3a9aac8>
  

• Now, sys.setdefaultencoding() proper

  All that it affects is implicit conversion str<->unicode. Now, utf-8 is the sanest encoding on the planet (backward-compatible with ASCII and all), the conversion now "just works", what could possibly go wrong?

  Well, anything. And that is the danger.

  • There may be some code that relies on the UnicodeError being thrown for non-ASCII input, or does the transcoding with an error handler, which now produces an unexpected result. And since all code is tested with the default setting, you're strictly on "unsupported" territory here, and no-one gives you guarantees about how their code will behave.
  • The transcoding may produce unexpected or unusable results if not everything on the system uses UTF-8 because Python 2 actually has multiple independent "default string encodings". (Remember, a program must work for the customer, on the customer's equipment.)
    • Again, the worst thing is you will never know that because the conversion is implicit -- you don't really know when and where it happens. (Python Zen, koan 2 ahoy!) You will never know why (and if) your code works on one system and breaks on another. (Or better yet, works in IDE and breaks in console.)

What you need is nm and its -D option:

$ nm -D /usr/lib/libopenal.so.1
.
.
.
00012ea0 T alcSetThreadContext
000140f0 T alcSuspendContext
         U atanf
         U calloc
.
.
.

Exported sumbols are indicated by a T. Required symbols that must be loaded from other shared objects have a U. Note that the symbol table does not include just functions, but exported variables as well.

See the nm manual page for more information.

This is what I'm using (very efficient):

function find_last () { find "${1:-.}" -type f -printf '%TY-%Tm-%Td %TH:%TM %P\n' 2>/dev/null | sort | tail -n "${2:-10}"; }

PROS:

• it spawns only 3 processes

USAGE:

find_last [dir [number]]

where:

• dir - a directory to be searched [current dir]
• number - number of newest files to display [10]

Output for find_last /etc 4 looks like this:

2019-07-09 12:12 cups/printers.conf
2019-07-09 14:20 salt/minion.d/_schedule.conf
2019-07-09 14:31 network/interfaces
2019-07-09 14:41 environment

The problem is that your PATH does not include the location of the node executable.

You can likely run node as "/usr/local/bin/node".

You can add that location to your path by running the following command to add a single line to your bashrc file:

echo 'export PATH=$PATH:/usr/local/bin' >> $HOME/.bashrc

The Official Documentation is clear about Path.

Linux Syntax: /home/joe/foo

Windows Syntax: C:\home\joe\foo

Note: joe is your username for these examples.

Pandas is pretty good at dealing with data. Here is one example how to use it:

import pandas as pd

# Read the CSV into a pandas data frame (df)
#   With a df you can do many things
#   most important: visualize data with Seaborn
df = pd.read_csv('filename.csv', delimiter=',')

# Or export it in many ways, e.g. a list of tuples
tuples = [tuple(x) for x in df.values]

# or export it as a list of dicts
dicts = df.to_dict().values()

One big advantage is that pandas deals automatically with header rows.

If you haven't heard of Seaborn, I recommend having a look at it.

See also: How do I read and write CSV files with Python?

Pandas #2

import pandas as pd

# Get data - reading the CSV file
import mpu.pd
df = mpu.pd.example_df()

# Convert
dicts = df.to_dict('records')

The content of df is:

     country   population population_time    EUR
0    Germany   82521653.0      2016-12-01   True
1     France   66991000.0      2017-01-01   True

If you happen to use Vavr(formerly known as Javaslang), this can be as easy as:

Iterable i = //...
Stream.ofAll(i);

Not only there is no need to declare it as false first, I would add few other improvements:

• use boolean instead of Boolean (which can also be null for no reason)

• assign during declaration:

  boolean isMatch = email1.equals(email2);
  

• ...and use final keyword if you can:

  final boolean isMatch = email1.equals(email2);
  

Last but not least:

if (isMatch == true)

can be expressed as:

if (isMatch)

which renders the isMatch flag not that useful, inlining it might not hurt readability. I suggest looking for some better courses/tutorials out there...

You could try:

print ''.join(ch for ch in some_string if ch.isalnum())

In older versions of IIS, you will not find Advance Settings so to enable Enable 32-bit Applications you have to execute the following commands:

cscript %SYSTEMDRIVE%\inetpub\adminscripts\adsutil.vbs SET W3SVC/AppPools/Enable32bitAppOnWin64 1

and

%SYSTEMROOT%\Microsoft.NET\Framework\v2.0.50727\aspnet_regiis.exe -i

Reference : Here

Also The function can help in sorting. To be more clear about sorting. strcmp() returns less than 0 if string1 sorts before string2, greater than 0 if string2 sorts before string1 or 0 if they are the same. For example

$first_string = "aabo";
$second_string = "aaao";
echo $n = strcmp($first_string,$second_string);

The function will return greater than zero, as aaao is sorting before aabo.

namespace MySingleton {
  interface IMySingleton {
      doSomething(): void;
  }
  class MySingleton implements IMySingleton {
      private usePrivate() { }
      doSomething() {
          this.usePrivate();
      }
  }
  export var Instance: IMySingleton = new MySingleton();
}

This way we can apply an interface, unlike in Ryan Cavanaugh's accepted answer.

You can use autoPrint() and set output to 'dataurlnewwindow' like this:

function printPDF() {
    var printDoc = new jsPDF();
    printDoc.fromHTML($('#pdf').get(0), 10, 10, {'width': 180});
    printDoc.autoPrint();
    printDoc.output("dataurlnewwindow"); // this opens a new popup,  after this the PDF opens the print window view but there are browser inconsistencies with how this is handled
}

Maybe someone is looking for a more generic approach, since Java 8 there is the Package java.util.function that allows to define Supplier Functions. You could have a function that takes a supplier and a default value as follows:

public static <T> T tryGetOrDefault(Supplier<T> supplier, T defaultValue) {
    try {
        return supplier.get();
    } catch (Exception e) {
        return defaultValue;
    }
}

With this function, you can execute any parsing method or even other methods that could throw an Exception while ensuring that no Exception can ever be thrown:

Integer i = tryGetOrDefault(() -> Integer.parseInt(stringValue), 0);
Long l = tryGetOrDefault(() -> Long.parseLong(stringValue), 0l);
Double d = tryGetOrDefault(() -> Double.parseDouble(stringValue), 0d);

Actually, you have at least 2 ways to do it, the first way is described by ColinD, you just configure the "resources" folder as Sources folder in IDEA. If the Resource Patterns contains the extension of your resource, then it will be copied to the output directory when you Make the project and output directory is automatically a classpath of your application.

Another common way is to add the "resources" folder to the classpath directly. Go to Project Structure | Modules | Your Module | Dependencies, click Add, Single-Entry Module Library, specify the path to the "resources" folder.

Yet another solution would be to put the log4j.properties file directly under the Source root of your project (in the default package directory). It's the same as the first way except you don't need to add another Source root in the Module Paths settings, the file will be copied to the output directory on Make.

If you want to test with different log4j configurations, it may be easier to specify a custom configuration file directly in the Run/Debug configuration, VM parameters filed like:

-Dlog4j.configuration=file:/c:/log4j.properties.

You need to create a C API for exposing the functionality of your C++ code. Basically, you will need to write C++ code that is declared extern "C" and that has a pure C API (not using classes, for example) that wraps the C++ library. Then you use the pure C wrapper library that you've created.

Your C API can optionally follow an object-oriented style, even though C is not object-oriented. Ex:

 // *.h file
 // ...
 #ifdef __cplusplus
 #define EXTERNC extern "C"
 #else
 #define EXTERNC
 #endif

 typedef void* mylibrary_mytype_t;

 EXTERNC mylibrary_mytype_t mylibrary_mytype_init();
 EXTERNC void mylibrary_mytype_destroy(mylibrary_mytype_t mytype);
 EXTERNC void mylibrary_mytype_doit(mylibrary_mytype_t self, int param);

 #undef EXTERNC

The answers by Bomber and Jakub (Thanks!) are correct and work for me in different situations.

For a quick glance at what was in the commit, I use

git show <replace this with your commit-id>

But I like to view a graphical Diff when studying something in detail and have set up a P4diff as my git diff and then use

git diff <replace this with your commit-id>^!

To create a user with sudo privileges is to put the user into /etc/sudoers, or make the user a member of a group specified in /etc/sudoers. And to make it password-less is to additionally specify NOPASSWD in /etc/sudoers.

Example of /etc/sudoers:

## Allow root to run any commands anywhere
root    ALL=(ALL)       ALL

## Allows people in group wheel to run all commands
%wheel  ALL=(ALL)       ALL

## Same thing without a password
%wheel  ALL=(ALL)       NOPASSWD: ALL

And instead of fiddling with /etc/sudoers file, we can create a new file in /etc/sudoers.d/ directory since this directory is included by /etc/sudoers by default, which avoids the possibility of breaking existing sudoers file, and also eliminates the dependency on the content inside of /etc/sudoers.

To achieve above in Ansible, refer to the following:

- name: sudo without password for wheel group
  copy:
    content: '%wheel ALL=(ALL:ALL) NOPASSWD:ALL'
    dest: /etc/sudoers.d/wheel_nopasswd
    mode: 0440

You may replace %wheel with other group names like %sudoers or other user names like deployer.

Easiest way is probably to convert from a VARCHAR to a DATE; then format it back to a VARCHAR again in the format you want;

            Console.WriteLine(Path.GetFileName(f));
        }
        foreach (string d in Directory.GetDirectories(dir))
        {
            Console.WriteLine(Path.GetFileName(d));
            DirectorySearch(d);
        }
    }
    catch (System.Exception ex)

        Console.WriteLine(ex.Message);

Note: the function shows only names without relative paths.

I like List comprehensions because of their Math (Set) syntax. So how about this:

L = [1, 2, 3, 4, 5, 6, 7]
odd_numbers = [y for x,y in enumerate(L) if x%2 != 0]
even_numbers = [y for x,y in enumerate(L) if x%2 == 0]

Basically, if you enumerate over a list, you'll get the index x and the value y. What I'm doing here is putting the value y into the output list (even or odd) and using the index x to find out if that point is odd (x%2 != 0).

Here's a short example of why typedef array can be confusingly inconsistent. The other answers provide a workaround.

#include <stdio.h>
typedef char type24[3];

int func(type24 a) {
        type24 b;
        printf("sizeof(a) is %zu\n",sizeof(a));
        printf("sizeof(b) is %zu\n",sizeof(b));
        return 0;
}

int main(void) {
        type24 a;
        return func(a);
}

This produces the output

sizeof(a) is 8
sizeof(b) is 3

because type24 as a parameter is a pointer. (In C, arrays are always passed as pointers.) The gcc8 compiler will issue a warning by default, thankfully.

In classic mode IIS works h ISAPI extensions and ISAPI filters directly. And uses two pipe lines , one for native code and other for managed code. You can simply say that in Classic mode IIS 7.x works just as IIS 6 and you dont get extra benefits out of IIS 7.x features.

In integrated mode IIS and ASP.Net are tightly coupled rather then depending on just two DLLs on Asp.net as in case of classic mode.

On Salesforce platform this error is caused by /, the solution is to escape these as //.

For c++ you should use g++.

It's the same compiler (e.g. the GNU compiler collection). GCC or G++ just choose a different front-end with different default options.

In a nutshell: if you use g++ the frontend will tell the linker that you may want to link with the C++ standard libraries. The gcc frontend won't do that (also it could link with them if you pass the right command line options).

If you run GNOME, you can use the system monitor (System->Administration->System Monitor) to kill processes as you would under Windows. KDE will have something similar.

I tried this DB insert method, but as it does not use the model, it ignored a sluggable trait I had on the model. So, given the Model for this table exists, as soon as its migrated, I figured the model would be available to use to insert data. And I came up with this:

public function up() {
        Schema::create('parent_categories', function (Blueprint $table) {
            $table->bigIncrements('id');
            $table->string('name');
            $table->string('slug');
            $table->timestamps();
        });
        ParentCategory::create(
            [
                'id' => 1,
                'name' => 'Occasions',
            ],
        );
    }

This worked correctly, and also took into account the sluggable trait on my Model to automatically generate a slug for this entry, and uses the timestamps too. NB. Adding the ID was no neccesary, however, I wanted specific IDs for my categories in this example. Tested working on Laravel 5.8

There are two types of WITH clauses:

Here is the FizzBuzz in SQL form, using a WITH common table expression (CTE).

;WITH mil AS (
 SELECT TOP 1000000 ROW_NUMBER() OVER ( ORDER BY c.column_id ) [n]
 FROM master.sys.all_columns as c
 CROSS JOIN master.sys.all_columns as c2
)                
 SELECT CASE WHEN n  % 3 = 0 THEN
             CASE WHEN n  % 5 = 0 THEN 'FizzBuzz' ELSE 'Fizz' END
        WHEN n % 5 = 0 THEN 'Buzz'
        ELSE CAST(n AS char(6))
     END + CHAR(13)
 FROM mil

Here is a select statement also using a WITH clause

SELECT * FROM orders WITH (NOLOCK) where order_id = 123

Abstract Methods and Classes:

An abstract class is a class that is declared abstract—it may or may not include abstract methods

Abstract classes cannot be instantiated, but they can be subclassed

An abstract method is a method that is declared without an implementation (without braces, and followed by a semicolon), like this:

abstract void moveTo(double deltaX, double deltaY);

If a class includes abstract methods, then the class itself must be declared abstract, as in:

public abstract class GraphicObject {
   // declare fields
   // declare nonabstract methods
   abstract void draw();
}

When an abstract class is subclassed, the subclass usually provides implementations for all of the abstract methods in its parent class. However, if it does not, then the subclass must also be declared abstract.

Since abstract classes and interfaces are related, have a look at below SE questions:

What is the difference between an interface and abstract class?

How should I have explained the difference between an Interface and an Abstract class?

Request.ServerVariables["REMOTE_ADDR"] should work - either directly in a view or in the controller action method body (Request is a property of Controller class in MVC, not Page).

It is working.. but you have to publish on a real IIS not the virtual one.

The Collection#filter method really does eager load all members. Filtering at the SQL level will be added in doctrine 2.3.

TLDR:

git pull is like running git fetch then git merge
git pull --rebase is like git fetch then git rebase

In reply to your first statement,

git pull is like a git fetch + git merge.

"In its default mode, git pull is shorthand for git fetch followed by git merge FETCH_HEAD" More precisely, git pull runs git fetch with the given parameters and then calls git merge to merge the retrieved branch heads into the current branch"

(Ref: https://git-scm.com/docs/git-pull)

For your second statement/question:

'But what is the difference between git pull VS git fetch + git rebase'

Again, from same source:
git pull --rebase

"With --rebase, it runs git rebase instead of git merge."

Now, if you wanted to ask

'the difference between merge and rebase'

that is answered here too:
https://git-scm.com/book/en/v2/Git-Branching-Rebasing
(the difference between altering the way version history is recorded)

The problem is that the else and if are two operators here. Since you open a new 'if' you need a corresponding 'end if'.

Thus:

declare
mark number :=50;
begin
  mark :=& mark;
  if (mark between 85 and 100) then
    dbms_output.put_line('mark is A ');
  else 
    if (mark between 50 and 65) then
      dbms_output.put_line('mark is D ');
    else 
      if (mark between 66 and 75) then
        dbms_output.put_line('mark is C ');
      else 
        if (mark between 76 and 84) then
          dbms_output.put_line('mark is B');
        else 
          dbms_output.put_line('mark is F');
        end if;
      end if;
    end if;
  end if;
end;
/

Alternatively you can use elsif:

declare
mark number :=50;
begin
  mark :=& mark;
  if (mark between 85 and 100)
    then
    dbms_output.put_line('mark is A ');
  elsif (mark between 50 and 65) then
    dbms_output.put_line('mark is D ');
  elsif (mark between 66 and 75) then
    dbms_output.put_line('mark is C ');
  elsif (mark between 76 and 84) then
    dbms_output.put_line('mark is B');
  else 
    dbms_output.put_line('mark is F');
  end if;
end;
/

If you want a readonly variable but don't want the client to have to change the way they access it, try this templated class:

template<typename MemberOfWhichClass, typename primative>                                       
class ReadOnly {
    friend MemberOfWhichClass;
public:
    template<typename number> inline bool   operator==(const number& y) const { return x == y; } 
    template<typename number> inline number operator+ (const number& y) const { return x + y; } 
    template<typename number> inline number operator- (const number& y) const { return x - y; } 
    template<typename number> inline number operator* (const number& y) const { return x * y; }  
    template<typename number> inline number operator/ (const number& y) const { return x / y; } 
    template<typename number> inline number operator<<(const number& y) const { return x << y; }
    template<typename number> inline number operator^(const number& y) const  { return x^y; }
    template<typename number> inline number operator~() const                 { return ~x; }
    template<typename number> inline operator number() const                  { return x; }
protected:
    template<typename number> inline number operator= (const number& y) { return x = y; }       
    template<typename number> inline number operator+=(const number& y) { return x += y; }      
    template<typename number> inline number operator-=(const number& y) { return x -= y; }      
    template<typename number> inline number operator*=(const number& y) { return x *= y; }      
    template<typename number> inline number operator/=(const number& y) { return x /= y; }      
    primative x;                                                                                
};      

Example Use:

class Foo {
public:
    ReadOnly<Foo, int> cantChangeMe;
};

Remember you'll need to add bitwise and unary operators as well! This is just to get you started

The OP asked, is it possible to reference a table, not how to add a table. So the working equivalent of

Sheets("Sheet1").Table("A_Table").Select

would be this statement:

Sheets("Sheet1").ListObjects("A_Table").Range.Select

or to select parts (like only the data in the table):

Dim LO As ListObject
Set LO = Sheets("Sheet1").ListObjects("A_Table")
LO.HeaderRowRange.Select        ' Select just header row
LO.DataBodyRange.Select         ' Select just data cells
LO.TotalsRowRange.Select        ' Select just totals row

For the parts, you may want to test for the existence of the header and totals rows before selecting them.

And seriously, this is the only question on referencing tables in VBA in SO? Tables in Excel make so much sense, but they're so hard to work with in VBA!

I have joined the answer from Lucas and "ASP.NET MVC Helpers, Merging two object htmlAttributes together" and plus controllerName to following code:

// Sample usage in CSHTML

 @Html.ActionImage("Edit",
       "EditController"
        new { id = MyId },
       "~/Content/Images/Image.bmp",
       new { width=108, height=129, alt="Edit" })

And the extension class for the code above:

using System.Collections.Generic;
using System.Reflection;
using System.Web.Mvc;

namespace MVC.Extensions

    public static class MvcHtmlStringExt
    {
        // Extension method
        public static MvcHtmlString ActionImage(

            imgBuilder.MergeAttribute("src", url.Content(imagePath));

            var dictAttributes = htmlAttributes.ToDictionary();

            if (dictAttributes != null)
            {

                }
            }                        

            string imgHtml = imgBuilder.ToString(TagRenderMode.SelfClosing);

            string anchorHtml = anchorBuilder.ToString(TagRenderMode.Normal);

            return MvcHtmlString.Create(anchorHtml);
        }

tl;dr

Standard ISO 8601 format is used by your input string.

Instant.parse ( "2011-08-12T20:17:46.384Z" ) 

ISO 8601

This format is defined by the sensible practical standard, ISO 8601.

The T separates the date portion from the time-of-day portion. The Z on the end means UTC (that is, an offset-from-UTC of zero hours-minutes-seconds). The Z is pronounced “Zulu”.

java.time

The old date-time classes bundled with the earliest versions of Java have proven to be poorly designed, confusing, and troublesome. Avoid them.

Instead, use the java.time framework built into Java 8 and later. The java.time classes supplant both the old date-time classes and the highly successful Joda-Time library.

The java.time classes use ISO 8601 by default when parsing/generating textual representations of date-time values.

The Instant class represents a moment on the timeline in UTC with a resolution of nanoseconds. That class can directly parse your input string without bothering to define a formatting pattern.

Instant instant = Instant.parse ( "2011-08-12T20:17:46.384Z" ) ;

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

You may exchange java.time objects directly with your database. Use a JDBC driver compliant with JDBC 4.2 or later. No need for strings, no need for java.sql.* classes. Hibernate 5 & JPA 2.2 support java.time.

Where to obtain the java.time classes?

• Java SE 8, Java SE 9, Java SE 10, Java SE 11, and later - Part of the standard Java API with a bundled implementation.
  • Java 9 brought some minor features and fixes.
• Java SE 6 and Java SE 7
  • Most of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • Later versions of Android (26+) bundle implementations of the java.time classes.
  • For earlier Android (<26), a process known as API desugaring brings a subset of the java.time functionality not originally built into Android.
    • If the desugaring does not offer what you need, the ThreeTenABP project adapts ThreeTen-Backport (mentioned above) to Android. See How to use ThreeTenABP….

Yes, you need to use PropTypes.arrayOf instead of PropTypes.array in the code, you can do something like this:

import PropTypes from 'prop-types';

MyComponent.propTypes = {
  annotationRanges: PropTypes.arrayOf(
    PropTypes.shape({
      start: PropTypes.string.isRequired,
      end: PropTypes.number.isRequired
    }).isRequired
  ).isRequired
}

Swift 4

DispatchQueue.main.asyncAfter(deadline: .now() + 0.1 + .milliseconds(500) + 
.microseconds(500) + .nanoseconds(1000)) {

You have to append your project's path to PYTHONPATH and make sure to use absolute imports.

For UNIX (Linux, OSX, ...)

export PYTHONPATH="${PYTHONPATH}:/path/to/your/project/"

For Windows

set PYTHONPATH=%PYTHONPATH%;C:\path\to\your\project\

Absolute imports

Assuming that we have the following project structure,

+-- myproject
    +-- mypackage
    ¦   +-- a.py
    +-- anotherpackage
        +-- b.py
        +-- c.py
        +-- mysubpackage
            +-- d.py

just make sure to reference each import starting from the project's root directory. For instance,

# in module a.py
import anotherpackage.mysubpackage.d

# in module b
import anotherpackage.c
import mypackage.a

For a more comprehensive explanation, refer to the article How to fix ModuleNotFoundError and ImportError

You can hack the useMemo hook to imitate a componentWillMount lifecycle event. Just do:

const Component = () => {
   useMemo(() => {
     // componentWillMount events
   },[]);
   useEffect(() => {
     // componentDidMount events
     return () => {
       // componentWillUnmount events
     }
   }, []);
};

You would need to keep the useMemo hook before anything that interacts with your state. This is not how it is intended but it worked for me for all componentWillMount issues.

This works because useMemo doesnt require to actually return a value and you dont have to actually use it as anything, but since it memorizes a value based on dependencies which will only run once ("[]") and its on top of our component it runs once when the component mounts before anything else.

My understanding of the words "If the function modifies that value, the modifications appear also within the scope of the calling function for both passing by value and by reference" is that they are an error.

Modifications made in a called function are not in scope of the calling function when passing by value.

Either you have mistyped the quoted words or they have been extracted out of whatever context made what appears to be wrong, right.

Could you please ensure you have correctly quoted your source and if there are no errors there give more of the text surrounding that statement in the source material.

You told your repository to rebase. It looks like you were on a commit (identified by SHA 9c168a5) and then did git rebase master or git pull --rebase master.

You are rebasing the branch master onto that commit. You can end the rebase via git rebase --abort. This would put back at the state that you were at before you started rebasing.

Solution for Windows

Go to File --> Set Path and add the folder containing the functions as Matlab files. (At least for Matlab 2007b on Vista)

If you have multiple layer proxies just like CDN + Load Balancer.
Using Laravel Request::ip() function will get right-most proxy IP but not client IP.
You may try following solution.

Adding to tfe's answer, you can recover with this process mentioned, unless it's commits are not garbage collected. Git branch is simply a pointer to a particular commit in the commit tree. But if you delete the pointer, and the commits on that branch are not merged into other existing branch, then git treats it as dangling commits and removes them during garbage collection, which it may run automatically periodically.

If your branch wasn't merged to an existing branch, and if it was garbage collected, then you will loose all commits up until the point from where branch was forked from an existing branch.

As stated in an article by Slicehost:

User setup

So let's start by adding the main user to the Apache user group:

sudo usermod -a -G www-data demo

That adds the user 'demo' to the 'www-data' group. Do ensure you use both the -a and the -G options with the usermod command shown above.

You will need to log out and log back in again to enable the group change.

Check the groups now:

groups
...
# demo www-data

So now I am a member of two groups: My own (demo) and the Apache group (www-data).

Folder setup

Now we need to ensure the public_html folder is owned by the main user (demo) and is part of the Apache group (www-data).

Let's set that up:

sudo chgrp -R www-data /home/demo/public_html

As we are talking about permissions I'll add a quick note regarding the sudo command: It's a good habit to use absolute paths (/home/demo/public_html) as shown above rather than relative paths (~/public_html). It ensures sudo is being used in the correct location.

If you have a public_html folder with symlinks in place then be careful with that command as it will follow the symlinks. In those cases of a working public_html folder, change each folder by hand.

Setgid

Good so far, but remember the command we just gave only affects existing folders. What about anything new?

We can set the ownership so anything new is also in the 'www-data' group.

The first command will change the permissions for the public_html directory to include the "setgid" bit:

sudo chmod 2750 /home/demo/public_html

That will ensure that any new files are given the group 'www-data'. If you have subdirectories, you'll want to run that command for each subdirectory (this type of permission doesn't work with '-R'). Fortunately new subdirectories will be created with the 'setgid' bit set automatically.

If we need to allow write access to Apache, to an uploads directory for example, then set the permissions for that directory like so:

sudo chmod 2770 /home/demo/public_html/domain1.com/public/uploads

The permissions only need to be set once as new files will automatically be assigned the correct ownership.

getJSONArray(attrname) will get you an array from the object of that given attribute name in your case what is happening is that for

^ its trying to search for a value "characters"

but you need to get into the array and then do a search for "characters"

try this

String json="{'abridged_cast':[{'name':'JeffBridges','id':'162655890','characters':['JackPrescott']},{'name':'CharlesGrodin','id':'162662571','characters':['FredWilson']},{'name':'JessicaLange','id':'162653068','characters':['Dwan']},{'name':'JohnRandolph','id':'162691889','characters':['Capt.Ross']},{'name':'ReneAuberjonois','id':'162718328','characters':['Bagley']}]}";

    JSONObject jsonResponse;
    try {
        ArrayList<String> temp = new ArrayList<String>();
        jsonResponse = new JSONObject(json);
        JSONArray movies = jsonResponse.getJSONArray("abridged_cast");
        for(int i=0;i<movies.length();i++){
            JSONObject movie = movies.getJSONObject(i);
            JSONArray characters = movie.getJSONArray("characters");
            for(int j=0;j<characters.length();j++){
                temp.add(characters.getString(j));
            }
        }
        Toast.makeText(this, "Json: "+temp, Toast.LENGTH_LONG).show();
    } catch (JSONException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

checked it :)

I had the same problem and solved it like this:

final YourType[] yourArray = ...;
return new Iterable<YourType>() {
  public Iterator<YourType> iterator() {
     return Iterators.forArray(yourArray);   // Iterators is a Google guava utility
  }
}

The iterator itself is a lazy UnmodifiableIterator but that's exactly what I needed.

The S parameter does not do anything on its own.

/S      Modifies the treatment of string after /C or /K (see below) 
/C      Carries out the command specified by string and then terminates  
/K      Carries out the command specified by string but remains  

Try something like this instead

Call Shell("cmd.exe /S /K" & "perl a.pl c:\temp", vbNormalFocus)

You may not even need to add "cmd.exe" to this command unless you want a command window to open up when this is run. Shell should execute the command on its own.

Shell("perl a.pl c:\temp")

-Edit-
To wait for the command to finish you will have to do something like @Nate Hekman shows in his answer here

Dim wsh As Object
Set wsh = VBA.CreateObject("WScript.Shell")
Dim waitOnReturn As Boolean: waitOnReturn = True
Dim windowStyle As Integer: windowStyle = 1

wsh.Run "cmd.exe /S /C perl a.pl c:\temp", windowStyle, waitOnReturn

I applied CSS styling to an anchored HREF attribute fully emulating the push button behaviors I needed (hover, active, background-color, etc., etc.). HTML markup is much simpler a-n-d eliminates the get/post complexity associated with using a form-based approach.

I used Joe's way to solve this issue :)

decimal argument = 123.456m;
int count = BitConverter.GetBytes(decimal.GetBits(argument)[3])[2];

Here's another JavaScript solution. Works very good and very fast.

https://github.com/dobiatowski/jQuery.FastEllipsis

Tested on Chrome, FF, IE on Windows and Mac.

There is no way to do so. Either use an HTML table, or put the same text on several cells.

like this:

| Can Reorder | 2nd operation |2nd operation |2nd operation |
| :---: | --- |
|1st operation|Normal Load <br/>Normal Store| Volatile Load <br/>MonitorEnter|Volatile Store<br/> MonitorExit|
|Normal Load <br/> Normal Store| | | No|
|Volatile Load <br/> MonitorEnter| No|No|No|
|Volatile store <br/> MonitorExit| | No|No|

which looks like

Add this single line in manifest (for permission)

<uses-permission android:name="android.permission.GET_ACCOUNTS" />

Then paste this code in your activity

private ArrayList<String> getPrimaryMailId() {
    ArrayList<String> accountsList = new ArrayList<String>();
    try {
        Account[] accounts = AccountManager.get(this).getAccountsByType("com.google");
        for (Account account : accounts) {
            accountsList.add(account.name);
            Log.e("GetPrimaryMailId ", account.name);
        }
    } catch (Exception e) {
        Log.e("GetPrimaryMailId", " Exception : " + e);
    }
    return accountsList;
}

The most important thing to know about async and await is that await doesn't wait for the associated call to complete. What await does is to return the result of the operation immediately and synchronously if the operation has already completed or, if it hasn't, to schedule a continuation to execute the remainder of the async method and then to return control to the caller. When the asynchronous operation completes, the scheduled completion will then execute.

The answer to the specific question in your question's title is to block on an async method's return value (which should be of type Task or Task<T>) by calling an appropriate Wait method:

public static async Task<Foo> GetFooAsync()
{
    // Start asynchronous operation(s) and return associated task.
    ...
}

public static Foo CallGetFooAsyncAndWaitOnResult()
{
    var task = GetFooAsync();
    task.Wait(); // Blocks current thread until GetFooAsync task completes
                 // For pedagogical use only: in general, don't do this!
    var result = task.Result;
    return result;
}

In this code snippet, CallGetFooAsyncAndWaitOnResult is a synchronous wrapper around asynchronous method GetFooAsync. However, this pattern is to be avoided for the most part since it will block a whole thread pool thread for the duration of the asynchronous operation. This an inefficient use of the various asynchronous mechanisms exposed by APIs that go to great efforts to provide them.

The answer at "await" doesn't wait for the completion of call has several, more detailed, explanations of these keywords.

Meanwhile, @Stephen Cleary's guidance about async void holds. Other nice explanations for why can be found at http://www.tonicodes.net/blog/why-you-should-almost-never-write-void-asynchronous-methods/ and https://jaylee.org/archive/2012/07/08/c-sharp-async-tips-and-tricks-part-2-async-void.html

I got it working by using Jimmy Zoto's answer and adding a second parameter to my belongsTo. Here it is:

First, as suggested by Jimmy Zoto, my code in blade from

$article->poster->name 

to

$article->poster['name']

Next is to add a second parameter in my belongsTo, from

return $this->belongsTo('App\User');

to

return $this->belongsTo('App\User', 'user_id');

in which user_id is my foreign key in the news table.

Use:

Random ran = new Random();
int x = ran.nextInt(6) + 5;

The integer x is now the random number that has a possible outcome of 5-10.

The documentation for WAITFOR() doesn't explicitly lay out the required string format.

This will wait for 2 seconds:

WAITFOR DELAY '00:00:02';

The format is hh:mi:ss.mmm.

I had the same problem when my plugin was depending on another project, which exported some packages in its manifest file. Instead of changing access rules, I have managed to solve the problem by adding the required packages into its Export-Package section. This makes the packages legally visible. Eclipse actually provides this fix on the "Access restriction" error marker.

You would want to pass a pointer by reference if you have a need to modify the pointer rather than the object that the pointer is pointing to.

This is similar to why double pointers are used; using a reference to a pointer is slightly safer than using pointers.

@media (max-width: @iphone-screen) {
  background-attachment:inherit;    
  background-size:cover;
  -webkit-background-size:cover;
}

All the previous posts are correct. There's more than one way to skin a cat. Here is another way to do the same thing: (just replace "what_ever_you_want_to_convert" with your string and run it in Oracle:

    set serveroutput on;
    DECLARE
    v_str VARCHAR2(1000);
    BEGIN
    --Create encoded value
    v_str := utl_encode.text_encode
    ('what_ever_you_want_to_convert','WE8ISO8859P1', UTL_ENCODE.BASE64);
    dbms_output.put_line(v_str);
    --Decode the value..
    v_str := utl_encode.text_decode
    (v_str,'WE8ISO8859P1', UTL_ENCODE.BASE64);
    dbms_output.put_line(v_str);
    END;
    /

[u'ABC'] would be a one-element list of unicode strings. Beautiful Soup always produces Unicode. So you need to convert the list to a single unicode string, and then convert that to ASCII.

I don't know exaxtly how you got the one-element lists; the contents member would be a list of strings and tags, which is apparently not what you have. Assuming that you really always get a list with a single element, and that your test is really only ASCII you would use this:

 soup[0].encode("ascii")

However, please double-check that your data is really ASCII. This is pretty rare. Much more likely it's latin-1 or utf-8.

 soup[0].encode("latin-1")


 soup[0].encode("utf-8")

Or you ask Beautiful Soup what the original encoding was and get it back in this encoding:

 soup[0].encode(soup.originalEncoding)

Another difference is that Sublime text is a closed source project, while Atom source code is/will be publicly available --although Github does not plan to release it as a real open source project. They want to give access to the code, without opening it to contributions.

Github made the code public: http://blog.atom.io/2014/05/06/atom-is-now-open-source.html

If you're willing to use underscore or lodash, you can use pick (or its opposite, omit).

Examples from underscore's docs:

_.pick({name: 'moe', age: 50, userid: 'moe1'}, 'name', 'age');
// {name: 'moe', age: 50}

Or with a callback (for lodash, use pickBy):

_.pick({name: 'moe', age: 50, userid: 'moe1'}, function(value, key, object) {
  return _.isNumber(value);
});
// {age: 50}

Just add this to your recycleview in xml

 android:nestedScrollingEnabled="false"

like this

<android.support.v7.widget.RecyclerView
                    android:background="#ffffff"
                    android:id="@+id/myrecycle"
                    android:layout_width="match_parent"
                    android:layout_height="match_parent"
                    android:nestedScrollingEnabled="false">

If it says the API key is listed as a header, more than likely you need to set it in the headers option of your http request. Normally something like this :

headers: {'Authorization': '[your API key]'}

Here is an example from another Question

$http({method: 'GET', url: '[the-target-url]', headers: {
  'Authorization': '[your-api-key]'}
});

Edit : Just saw you wanted to store the response in a variable. In this case I would probably just use AJAX. Something like this :

$.ajax({ 
   type : "GET", 
   url : "[the-target-url]", 
   beforeSend: function(xhr){xhr.setRequestHeader('Authorization', '[your-api-key]');},
   success : function(result) { 
       //set your variable to the result 
   }, 
   error : function(result) { 
     //handle the error 
   } 
 }); 

I got this from this question and I'm at work so I can't test it at the moment but looks solid

Edit 2: Pretty sure you should be able to use this line :

headers: {'Authorization': '[your API key]'},

instead of the beforeSend line in the first edit. This may be simpler for you

Mehrwolf below is correct, but here is a heuristic which may help:

If you are working in a 2-dimensional coordinate system, which is often the case for programming the inverse tangent, you should use definitely use atan2. It will give the full 2 pi range of angles and take care of zeros in the x coordinate for you.

Another way of saying this is that atan(y/x) is virtually always wrong. Only use atan if the argument cannot be thought of as y/x.

This is not a bug- you can only transition on ordinal/calculable properties (an easy way of thinking of this is any property with a numeric start and end number value..though there are a few exceptions).

This is because transitions work by calculating keyframes between two values, and producing an animation by extrapolating intermediate amounts.

visibility in this case is a binary setting (visible/hidden), so once the transition duration elapses, the property simply switches state, you see this as a delay- but it can actually be seen as the final keyframe of the transition animation, with the intermediary keyframes not having been calculated (what constitutes the values between hidden/visible? Opacity? Dimension? As it is not explicit, they are not calculated).

opacity is a value setting (0-1), so keyframes can be calculated across the duration provided.

A list of transitionable (animatable) properties can be found here

You can alternatively use NamedParameterJdbcTemplate (naming can be useful when you have many parameters)

Map<String, Object> params = new HashMap<>();
params.put("var1",value1); 
params.put("var2",value2); 
namedJdbcTemplate.update(
    "INSERT INTO schema.tableName (column1, column2) VALUES (:var1, :var2)",
    params
);

The idea behind reporting progress with the background worker is through sending a 'percent completed' event. You are yourself responsible for determining somehow 'how much' work has been completed. Unfortunately this is often the most difficult part.

In your case, the bulk of the work is database-related. There is to my knowledge no way to get progress information from the DB directly. What you can try to do however, is split up the work dynamically. E.g., if you need to read a lot of data, a naive way to implement this could be.

• Determine how many rows are to be retrieved (SELECT COUNT(*) FROM ...)

• Divide the actual reading in smaller chunks, reporting progress every time one chunk is completed:

  for (int i = 0; i < count; i++)
  {
      bgWorker.ReportProgress((100 * i) / count);
      // ... (read data for step i)
  }
  

In Java 9, using List#of, which is an Immutable List Static Factory Methods, become more simpler.

 String s = "a,b,c,d,e,.........";
 List<String> lst = List.of(s.split(","));

This is what working for me

<android.support.v4.widget.NestedScrollView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fillViewport="true"
    app:layout_behavior="@string/appbar_scrolling_view_behavior">

    <android.support.v7.widget.RecyclerView
        android:id="@+id/rv_recycler_view"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:layout_behavior="@string/appbar_scrolling_view_behavior"/>
</android.support.v4.widget.NestedScrollView>

Just add parenthesis around the query:

set @user = 123456;
set @group = (select GROUP from USER where User = @user);
select * from USER where GROUP = @group;

I had a similar issue but from reading this question I figured I could run on UI thread:

YourActivity.this.runOnUiThread(new Runnable() {
    public void run() {
        alertDialog.show();
    }
});

Seems to do the trick for me.

There's no way to specify a StringComparer at the point where you try to get a value. If you think about it, "foo".GetHashCode() and "FOO".GetHashCode() are totally different so there's no reasonable way you could implement a case-insensitive get on a case-sensitive hash map.

You can, however, create a case-insensitive dictionary in the first place using:-

var comparer = StringComparer.OrdinalIgnoreCase;
var caseInsensitiveDictionary = new Dictionary<string, int>(comparer);

Or create a new case-insensitive dictionary with the contents of an existing case-sensitive dictionary (if you're sure there are no case collisions):-

var oldDictionary = ...;
var comparer = StringComparer.OrdinalIgnoreCase;
var newDictionary = new Dictionary<string, int>(oldDictionary, comparer);

This new dictionary then uses the GetHashCode() implementation on StringComparer.OrdinalIgnoreCase so comparer.GetHashCode("foo") and comparer.GetHashcode("FOO") give you the same value.

Alternately, if there are only a few elements in the dictionary, and/or you only need to lookup once or twice, you can treat the original dictionary as an IEnumerable<KeyValuePair<TKey, TValue>> and just iterate over it:-

var myKey = ...;
var myDictionary = ...;
var comparer = StringComparer.OrdinalIgnoreCase;
var value = myDictionary.FirstOrDefault(x => String.Equals(x.Key, myKey, comparer)).Value;

Or if you prefer, without the LINQ:-

var myKey = ...;
var myDictionary = ...;
var comparer = StringComparer.OrdinalIgnoreCase;
int? value;
foreach (var element in myDictionary)
{
  if (String.Equals(element.Key, myKey, comparer))
  {
    value = element.Value;
    break;
  }
}

This saves you the cost of creating a new data structure, but in return the cost of a lookup is O(n) instead of O(1).

Any decent text editor has a search&replace facility that supports regular expressions.

If however, you have reason to reinvent the wheel in Java, you can do:

Path path = Paths.get("test.txt");
Charset charset = StandardCharsets.UTF_8;

String content = new String(Files.readAllBytes(path), charset);
content = content.replaceAll("foo", "bar");
Files.write(path, content.getBytes(charset));

This only works for Java 7 or newer. If you are stuck on an older Java, you can do:

String content = IOUtils.toString(new FileInputStream(myfile), myencoding);
content = content.replaceAll(myPattern, myReplacement);
IOUtils.write(content, new FileOutputStream(myfile), myencoding);

In this case, you'll need to add error handling and close the streams after you are done with them.

IOUtils is documented at http://commons.apache.org/proper/commons-io/javadocs/api-release/org/apache/commons/io/IOUtils.html

You can use stepi or nexti (which can be abbreviated to si or ni) to step through your machine code.

Try this one.

ALTER TABLE tb_TableName
ALTER COLUMN Record_Status VARCHAR(20) NOT NULL

ALTER TABLE tb_TableName
ADD CONSTRAINT DEF_Name DEFAULT '' FOR Record_Status

There is a plugin for that, jquery-formatcurrency.

You can set the decimal separator (default .) and currency symbol (default $) for custom formatting or use the built in International Support. The format for Bahasa Indonesia (Indonesia) - Indonesian (Indonesia) coded id-ID looks closest to what you have provided.

Groovy doesn't have an import keyword like typical scripting languages that will do a literal include of another file's contents (alluded to here: Does groovy provide an include mechanism?).
Because of its object/class oriented nature, you have to "play games" to make things like this work. One possibility is to make all your utility functions static (since you said they don't use objects) and then perform a static import in the context of your executing shell. Then you can call these methods like "global functions".
Another possibility would be using a Binding object (http://groovy.codehaus.org/api/groovy/lang/Binding.html) while creating your Shell and binding all the functions you want to the methods (the downside here would be having to enumerate all methods in the binding but you could perhaps use reflection). Yet another solution would be to override methodMissing(...) in the delegate object assigned to your shell which allows you to basically do dynamic dispatch using a map or whatever method you'd like.

Several of these methods are demonstrated here: http://www.nextinstruction.com/blog/2012/01/08/creating-dsls-with-groovy/. Let me know if you want to see an example of a particular technique.

SELECT * 
INTO target
FROM  source
WHERE 1 = 2

"location" directive should be inside a 'server' directive, e.g.

server {
    listen       8765;

    location / {
        resolver 8.8.8.8;
        proxy_pass http://$http_host$uri$is_args$args;
    }

    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   html;
    }
}

Somewhat similar to your original attempt, but more Pythonic, is to use Python's standard negative-indexing convention to count backwards from the end:

df[df.columns[-1]]

To complement the previous answers, I whipped up a quick class to write to CSV files. It makes it easier to manage and close open files and achieve consistency and cleaner code if you have to deal with multiple files.

class CSVWriter():

    filename = None
    fp = None
    writer = None

    def __init__(self, filename):
        self.filename = filename
        self.fp = open(self.filename, 'w', encoding='utf8')
        self.writer = csv.writer(self.fp, delimiter=';', quotechar='"', quoting=csv.QUOTE_ALL, lineterminator='\n')

    def close(self):
        self.fp.close()

    def write(self, elems):
        self.writer.writerow(elems)

    def size(self):
        return os.path.getsize(self.filename)

    def fname(self):
        return self.filename

Example usage:

mycsv = CSVWriter('/tmp/test.csv')
mycsv.write((12,'green','apples'))
mycsv.write((7,'yellow','bananas'))
mycsv.close()
print("Written %d bytes to %s" % (mycsv.size(), mycsv.fname()))

[Range(0.01,100000000,ErrorMessage = "Price must be greter than zero !")]

Mainly I'm using this:

list.removeAll(Collections.singleton(null));

But after I learned Java 8, I switched to this:

List.removeIf(Objects::isNull);

First off, you need to get a MemberInfo object that represents that property. You will need to do some form of reflection:

MemberInfo property = typeof(Class1).GetProperty("Name");

(I'm using "old-style" reflection, but you can also use an expression tree if you have access to the type at compile-time)

Then you can fetch the attribute and obtain the value of the DisplayName property:

var attribute = property.GetCustomAttributes(typeof(DisplayNameAttribute), true)
      .Cast<DisplayNameAttribute>().Single();
string displayName = attribute.DisplayName;

() parentheses are required typo error

Reinstall node and python with x32 versions.
I spent a lot of time with this error:

Failed to load c++ bson extension

and finally, when I installed module node-gyp (for building native addons) and even installed windows SDK with visual studio - nodejs didn't recognize assembled module bson.node as a module. After reinstalling the problem is gone.

Again, What does this error mean?

Actually, it's even not error. You still can use mongoose. But in this case, instead of fast native realization of bson module, you got js-realization, which is slower.

I saw many tips like: "edit path deep inside node_modules..." - which is totally useless, because it does not solve the problem, but just turned off the error messages.

If sorting of objects needs to be based on natural order then use Comparable whereas if your sorting needs to be done on attributes of different objects, then use Comparator in Java.

Main differences between Comparable and Comparator:

Pythonic way to do this is ...

np.divide(data.T,vector).T

This takes care of reshaping and also the results are in floating point format. In other answers results are in rounded integer format.

#NOTE: No of columns in both data and vector should match

Since you seem to be on windows you can do this so python <filename.py>. Check that python's bin folder is in your PATH, or you can do c:\python23\bin\python <filename.py>. Python is an interpretive language and so you need the interpretor to run your file, much like you need java runtime to run a jar file.

I know this is old, but wanted to share my solution.

In my case the issue was in my .htaccess as I added variables to raise my PHP's max upload limit. My code was like this:

php_value post_max_size 50MB
php_value upload_max_filesize 50MB

Later I notice that the values should like xxM not xxMB and when I changed it to:

php_value post_max_size 50M
php_value upload_max_filesize 50M

now my $_POST returned the data as normal before. Hope this helps someone in the future.

If you just want to programmatically (as oppossed to giving the user a link to open in a browser) download a file through the Google Drive API, I would suggest using the downloadUrl of the file instead of the webContentLink, as documented here: https://developers.google.com/drive/web/manage-downloads

This is what worked for me...

$('#dialog').live("dialogclose", function(){
   //code to run on dialog close
});

Your web form shouldn't have all of that markup (like the <html> tag). Since it has a master page, you just start with the content tag. Your aspx page should look like this:

<%@ Page Language="vb" AutoEventWireup="false" CodeBehind="Default.aspx.vb" Inherits="WebUI._Default" MasterPageFile="~/Site1.Master" %>

<asp:content id="Content1" ContentPlaceHolderID="ContentPlaceHolder1" runat="server">
   This is the body!
</asp:content>

When you're adding a new aspx page make sure to check "select master page" in the "add new item" dialog.

a_list = [
          [1,2],
          [1,2],
          [2,3],
          [3,4]
]

print (list(map(list,set(map(tuple,a_list)))))

outputs: [[1, 2], [3, 4], [2, 3]]
