I solved this by using this way -

    @RunWith(SpringRunner.class)
    @EnableJpaRepositories(basePackages={"com.path.repositories"})
    @EntityScan(basePackages={"com.model"})
    @TestPropertySource("classpath:application.properties")
    @ContextConfiguration(classes = {ApiTestConfig.class,SaveActionsServiceImpl.class})
    public class SaveCriticalProcedureTest {

        @Autowired
        private SaveActionsService saveActionsService;
        .......
        .......
}

You're right:

$('#myTableRow').remove();

This works fine if your row has an id, such as:

<tr id="myTableRow"><td>blah</td></tr>

If you don't have an id, you can use any of jQuery's plethora of selectors.

Example for escaped string with variable:

@some-variable-height: 10px;

...

div {
    height: ~"calc(100vh - "@some-variable-height~")";
}

compiles to

div {
    height: calc(100vh - 10px );
}

Had this happen intermittently, turns out I only had this issue when the list was scrolled after a 'load more' last item was clicked. If the list wasn't scrolled, everything worked fine.

After MUCH debugging, it was a bug on my part, but an inconsistency in the Android code also.

When the validation happens, this code is executed in ListView

        } else if (mItemCount != mAdapter.getCount()) {
            throw new IllegalStateException("The content of the adapter has changed but "
                    + "ListView did not receive a notification. Make sure the content of "

But when onChange happens it fires this code in AdapterView (parent of ListView)

    @Override
    public void onChanged() {
        mDataChanged = true;
        mOldItemCount = mItemCount;
        mItemCount = getAdapter().getCount();

Notice the way the Adapter is NOT guaranteed to be the Same!

In my case, since it was a 'LoadMoreAdapter' I was returning the WrappedAdapter in the getAdapter call (for access to the underlying objects). This resulted in the counts being different due to the extra 'Load More' item and the Exception being thrown.

I only did this because the docs make it seem like it's ok to do

ListView.getAdapter javadoc

Returns the adapter currently in use in this ListView. The returned adapter might not be the same adapter passed to setAdapter(ListAdapter) but might be a WrapperListAdapter.

Guys thank you for your help. I think all of this answers works. However i think my byte array contains raw bytes. That's why all of those solutions didnt work for my code.

However i found a solution. Maybe this solution helps other coders who have problem like mine.

static byte[] PadLines(byte[] bytes, int rows, int columns) {
   int currentStride = columns; // 3
   int newStride = columns;  // 4
   byte[] newBytes = new byte[newStride * rows];
   for (int i = 0; i < rows; i++)
       Buffer.BlockCopy(bytes, currentStride * i, newBytes, newStride * i, currentStride);
   return newBytes;
 }

 int columns = imageWidth;
 int rows = imageHeight;
 int stride = columns;
 byte[] newbytes = PadLines(imageData, rows, columns);

 Bitmap im = new Bitmap(columns, rows, stride, 
          PixelFormat.Format8bppIndexed, 
          Marshal.UnsafeAddrOfPinnedArrayElement(newbytes, 0));

 im.Save("C:\\Users\\musa\\Documents\\Hobby\\image21.bmp");

This solutions works for 8bit 256 bpp (Format8bppIndexed). If your image has another format you should change PixelFormat .

And there is a problem with colors right now. As soon as i solved this one i will edit my answer for other users.

*PS = I am not sure about stride value but for 8bit it should be equal to columns.

And also this function Works for me.. This function copies 8 bit greyscale image into a 32bit layout.

public void SaveBitmap(string fileName, int width, int height, byte[] imageData)
        {

            byte[] data = new byte[width * height * 4];

            int o = 0;

            for (int i = 0; i < width * height; i++)
            {
                byte value = imageData[i];


                data[o++] = value;
                data[o++] = value;
                data[o++] = value;
                data[o++] = 0; 
            }

            unsafe
            {
                fixed (byte* ptr = data)
                {

                    using (Bitmap image = new Bitmap(width, height, width * 4,
                                PixelFormat.Format32bppRgb, new IntPtr(ptr)))
                    {

                        image.Save(Path.ChangeExtension(fileName, ".jpg"));
                    }
                }
            }
        }

Following query helped me. Instead of using LIKE, you can use ~*.

select id, name from hosts where name ~* 'julia|lena|jack';

Do a row div.

Like this:

<link href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-beta.3/css/bootstrap.min.css" rel="stylesheet" integrity="sha384-Zug+QiDoJOrZ5t4lssLdxGhVrurbmBWopoEl+M6BdEfwnCJZtKxi1KgxUyJq13dy" crossorigin="anonymous">_x000D_
<div class="grid">_x000D_
    <div class="row">_x000D_
        <div class="col-lg-3 col-md-3 col-sm-3 col-xs-12 bg-success">Under me should be a DIV</div>_x000D_
        <div class="col-lg-6 col-md-6 col-sm-5 col-xs-12 bg-danger">Under me should be a DIV</div>_x000D_
    </div>_x000D_
    <div class="row">_x000D_
        <div class="col-lg-3 col-md-3 col-sm-4 col-xs-12 bg-warning">I am the last DIV</div>_x000D_
    </div>_x000D_
</div>

You could use curl instead. It is installed by default into /usr/bin.

I think I found another solution to this question.

Go to Project > Properties > Java Build Path > tab [Order and Export] > Tick Android Version Checkbox Then if your workspace does not build automatically…

Properties again > Build Project

I found out a solution about excluding SecurityAutoConfiguration class.

Example:

@SpringBootApplication(exclude = {SecurityAutoConfiguration.class })
public class ReportApplication {

    public static void main(String[] args) throws Exception {
        SpringApplication.run(MyApplication.class, args);
    }
}

You may also try standard sql un-pivoting method by using a sequence of logic with the following code.. The following code has 3 steps:

1. create multiple copies for each row using cross join (also creating subject column in this case)
2. create column "marks" and fill in relevant values using case expression ( ex: if subject is science then pick value from science column)

3. remove any null combinations ( if exists, table expression can be fully avoided if there are strictly no null values in base table)

    select *
    from 
    (
       select name, subject,
       case subject
       when 'Maths' then maths
       when 'Science' then science
       when 'English' then english
       end as Marks
   from studentmarks
   Cross Join (values('Maths'),('Science'),('English')) AS Subjct(Subject)
   )as D
   where marks is not null;
   

you can use AlertDialog as ProgressDialog refer below code for the ProgressDialog. This function you need to call whenever you show a progress dialog.

Code:

    public void setProgressDialog() {

    int llPadding = 30;
    LinearLayout ll = new LinearLayout(this);
    ll.setOrientation(LinearLayout.HORIZONTAL);
    ll.setPadding(llPadding, llPadding, llPadding, llPadding);
    ll.setGravity(Gravity.CENTER);
    LinearLayout.LayoutParams llParam = new LinearLayout.LayoutParams(
            LinearLayout.LayoutParams.WRAP_CONTENT,
            LinearLayout.LayoutParams.WRAP_CONTENT);
    llParam.gravity = Gravity.CENTER;
    ll.setLayoutParams(llParam);

    ProgressBar progressBar = new ProgressBar(this);
    progressBar.setIndeterminate(true);
    progressBar.setPadding(0, 0, llPadding, 0);
    progressBar.setLayoutParams(llParam);

    llParam = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT,
            ViewGroup.LayoutParams.WRAP_CONTENT);
    llParam.gravity = Gravity.CENTER;
    TextView tvText = new TextView(this);
    tvText.setText("Loading ...");
    tvText.setTextColor(Color.parseColor("#000000"));
    tvText.setTextSize(20);
    tvText.setLayoutParams(llParam);

    ll.addView(progressBar);
    ll.addView(tvText);

    AlertDialog.Builder builder = new AlertDialog.Builder(this);
    builder.setCancelable(true);
    builder.setView(ll);

    AlertDialog dialog = builder.create();
    dialog.show();
    Window window = dialog.getWindow();
    if (window != null) {
        WindowManager.LayoutParams layoutParams = new WindowManager.LayoutParams();
        layoutParams.copyFrom(dialog.getWindow().getAttributes());
        layoutParams.width = LinearLayout.LayoutParams.WRAP_CONTENT;
        layoutParams.height = LinearLayout.LayoutParams.WRAP_CONTENT;
        dialog.getWindow().setAttributes(layoutParams);
    }
}

If you want to get the week number with the year, Grant Shannon's solution using strftime works, but you need to make some corrections for the dates around january 1st. For instance, 2016-01-03 (yyyy-mm-dd) is week 53 of year 2015, not 2016. And 2018-12-31 is week 1 of 2019, not of 2018. This codes provides some examples and a solution. In column "yearweek" the years are sometimes wrong, in "yearweek2" they are corrected (rows 2 and 5).

library(dplyr)
library(lubridate)

# create a testset
test <- data.frame(matrix(data = c("2015-12-31",
                                   "2016-01-03",
                                   "2016-01-04",
                                   "2018-12-30",
                                   "2018-12-31",
                                   "2019-01-01") , ncol=1, nrow = 6 ))
# add a colname
colnames(test) <- "date_txt"

# this codes provides correct year-week numbers
test <- test %>%
        mutate(date = as.Date(date_txt, format = "%Y-%m-%d")) %>%
        mutate(yearweek = as.integer(strftime(date, format = "%Y%V"))) %>%
        mutate(yearweek2 = ifelse(test = day(date) > 7 & substr(yearweek, 5, 6) == '01',
                                 yes  = yearweek + 100,
                                 no   = ifelse(test = month(date) == 1 & as.integer(substr(yearweek, 5, 6)) > 51,
                                               yes  = yearweek - 100,
                                               no   = yearweek)))
# print the result
print(test)

Use the tee command:

echo "hello" | tee logfile.txt

Go to Start and search for cmd. Right click on it, properties then set the Target path in quotes. This worked fine for me.

In my case, I needed to get the total rows from a ResultSet and also access the ResultSet values ??if the total rows did not reach the limit of an XLS file.

For that, I had to make two adjustments to my code:

1) Change in object construction PreparedStatement

A default ResultSet object has a cursor that moves forward only. Thus, you can iterate through it only once and only from the first row to the last row. It is possible to produce ResultSet objects that are scrollable. The following code fragment illustrates how to make a result set that is scrollable and insensitive to updates by others.

PreparedStatement ps = connection.prepareStatement(sql, ResultSet.TYPE_SCROLL_INSENSITIVE, 
ResultSet.CONCUR_READ_ONLY);

2) Get total rows. The following code fragment illustrates how:

ResultSet rs = ps.executeQuery();
rs.last();
int totalRowsResult = rs.getRow();

PS: If the number of records of the query result is too large, you may run out of memory on the Java server by getting an exception: java.lang.OutOfMemoryError: Java heap space. This exception will occur when executing the rs.last () method

3) Access again the ResultSet and you don't get the message: exhaused result set. So, vou need reset the result set to the top, using rs.first() or rs.absolute(1). The following code fragment illustrates how:

rs.first();
System.out.println(rs.getString(1));

You will need to add the application.properties file in your classpath.

If you are using Maven or Gradle, you can just put the file under src/main/resources.
If you are not using Maven or any other build tools, put that under your src folder and you should be fine.

Then you can just add an entry server.port = xxxx in the properties file.

String strJson="{\"Employee\":
[{\"id\":\"101\",\"name\":\"Pushkar\",\"salary\":\"5000\"},
{\"id\":\"102\",\"name\":\"Rahul\",\"salary\":\"4000\"},
{\"id\":\"103\",\"name\":\"tanveer\",\"salary\":\"56678\"}]}";

This is an example of a JSON string with Employee as object, then multiple strings and values in an array as a reference to @cregox...

A bit complicated but can explain a lot in a single JSON string.

You have to write this code instead of return View(); :

return RedirectToAction("ActionName", "ControllerName");

This was driving me bonkers as the .astype() solution above didn't work for me. But I found another way. Haven't timed it or anything, but might work for others out there:

t1 = pd.to_datetime('1/1/2015 01:00')
t2 = pd.to_datetime('1/1/2015 03:30')

print pd.Timedelta(t2 - t1).seconds / 3600.0

...if you want hours. Or:

print pd.Timedelta(t2 - t1).seconds / 60.0

...if you want minutes.

If you have stumbled upon this problem due to getting this error recently out of nowhere in react native- this is due to the latest BREAKING CHANGE in Google Play service and Firebase. Check this thread first -

And solution would mostly be like this -

Solution

It is possible to use str_detect of the stringr package included in the tidyverse package. str_detect returns True or False as to whether the specified vector contains some specific string. It is possible to filter using this boolean value. See Introduction to stringr for details about stringr package.

The good things about Stringr

We should use rather stringr::str_detect() than base::grepl(). This is because there are the following reasons.

• The functions provided by the stringr package start with the prefix str_, which makes the code easier to read.
• The first argument of the functions of stringr package is always the data.frame (or value), then comes the parameters.(Thank you Paolo)

object <- "stringr"
# The functions with the same prefix `str_`.
# The first argument is an object.
stringr::str_count(object) # -> 7
stringr::str_sub(object, 1, 3) # -> "str"
stringr::str_detect(object, "str") # -> TRUE
stringr::str_replace(object, "str", "") # -> "ingr"
# The function names without common points.
# The position of the argument of the object also does not match.
base::nchar(object) # -> 7
base::substr(object, 1, 3) # -> "str"
base::grepl("str", object) # -> TRUE
base::sub("str", "", object) # -> "ingr"

Benchmark

The results of the benchmark test are as follows. For large dataframe, str_detect is faster.

library(rbenchmark)
library(tidyverse)

# The data. Data expo 09. ASA Statistics Computing and Graphics 
# http://stat-computing.org/dataexpo/2009/the-data.html
df <- read_csv("Downloads/2008.csv")
print(dim(df))
# [1] 7009728      29

benchmark(
  "str_detect" = {df %>% filter(str_detect(Dest, 'MCO|BWI'))},
  "grepl" = {df %>% filter(grepl('MCO|BWI', Dest))},
  replications = 10,
  columns = c("test", "replications", "elapsed", "relative", "user.self", "sys.self"))
# test replications elapsed relative user.self sys.self
# 2      grepl           10  16.480    1.513    16.195    0.248
# 1 str_detect           10  10.891    1.000     9.594    1.281

I have added an extra update method onto my repository base class that's similar to the update method generated by Scaffolding. Instead of setting the entire object to "modified", it sets a set of individual properties. (T is a class generic parameter.)

public void Update(T obj, params Expression<Func<T, object>>[] propertiesToUpdate)
{
    Context.Set<T>().Attach(obj);

    foreach (var p in propertiesToUpdate)
    {
        Context.Entry(obj).Property(p).IsModified = true;
    }
}

And then to call, for example:

public void UpdatePasswordAndEmail(long userId, string password, string email)
{
    var user = new User {UserId = userId, Password = password, Email = email};

    Update(user, u => u.Password, u => u.Email);

    Save();
}

I like one trip to the database. Its probably better to do this with view models, though, in order to avoid repeating sets of properties. I haven't done that yet because I don't know how to avoid bringing the validation messages on my view model validators into my domain project.

If you read the help file for ?boxplot, you'll see there is a names= parameter.

     boxplot(apple, banana, watermelon, names=c("apple","banana","watermelon"))

If you want to build DOM you can use jsdom.

There's also cheerio, it has the jQuery interface and it's a lot faster than older versions of jsdom, although these days they are similar in performance.

You might wanna have a look at htmlparser2, which is a streaming parser, and according to its benchmark, it seems to be faster than others, and no DOM by default. It can also produce a DOM, as it is also bundled with a handler that creates a DOM. This is the parser that is used by cheerio.

parse5 also looks like a good solution. It's fairly active (11 days since the last commit as of this update), WHATWG-compliant, and is used in jsdom, Angular, and Polymer.

And if you want to parse HTML for web scraping, you can use YQL¹. There is a node module for it. YQL I think would be the best solution if your HTML is from a static website, since you are relying on a service, not your own code and processing power. Though note that it won't work if the page is disallowed by the robot.txt of the website, YQL won't work with it.

If the website you're trying to scrape is dynamic then you should be using a headless browser like phantomjs. Also have a look at casperjs, if you're considering phantomjs. And you can control casperjs from node with SpookyJS.

Beside phantomjs there's zombiejs. Unlike phantomjs that cannot be embedded in nodejs, zombiejs is just a node module.

There's a nettuts+ toturial for the latter solutions.

¹ Since Aug. 2014, YUI library, which is a requirement for YQL, is no longer actively maintained, source

Swift 5/iOS 13

To change color of title in controller:

UINavigationBar.appearance().titleTextAttributes = [NSAttributedString.Key.foregroundColor: UIColor.white]

mvn -version

export PATH=$PATH:/opt/apache-maven-3.6.0/bin

Try loading your javascript after.

Try this:

<h2>Hello World!</h2>
<p id="myParagraph">This is an example website</p>

<form>
  <input type="text" id="myTextfield" placeholder="Type your name" />
  <input type="submit" id="myButton" value="Go" />
</form>

<script src="js/script.js" type="text/javascript"></script>

It's because you're trying to assign an object by reference. Remove the ampersand and your script should work as intended.

There are a few ways depending on some data rules that you have not included, but here is one way using what you gave.

SELECT
    t1.Field1,
    t2.Field2
FROM Table1 t1
    LEFT JOIN Table1 t2 ON t1.FK = t2.FK AND t2.Field1 IS NULL

Another way:

SELECT
    t1.Field1,
    (SELECT Field2 FROM Table2 t2 WHERE t2.FK = t1.FK AND Field1 IS NULL) AS Field2
FROM Table1 t1

use ONLY

function init() { 
    about = document.getElementById("about");
    about.style.color = 'blue';
}

.innerHTML() sets or gets the HTML syntax describing the element's descendants., All you need is an object here.

Problem Cause

In mac os image rendering back end of matplotlib (what-is-a-backend to render using the API of Cocoa by default). There are Qt4Agg and GTKAgg and as a back-end is not the default. Set the back end of macosx that is differ compare with other windows or linux os.

Solution

• I assume you have installed the pip matplotlib, there is a directory in your root called ~/.matplotlib.
• Create a file ~/.matplotlib/matplotlibrc there and add the following code: backend: TkAgg

From this link you can try different diagrams.

@SolutionYogi's answer works like a charm, but it seems that using $.each is less straightforward and efficient than directly appending listitems :

var mylist = $('#list');
var listitems = mylist.children('li').get();

listitems.sort(function(a, b) {
   return $(a).text().toUpperCase().localeCompare($(b).text().toUpperCase());
})

mylist.empty().append(listitems);

Fiddle

This is super old, but I figured I'd add my 2c. DATE_FORMAT does indeed return a string, but I was looking for the CAST function, in the situation that I already had a datetime string in the database and needed to pattern match against it:

http://dev.mysql.com/doc/refman/5.0/en/cast-functions.html

In this case, you'd use:

CAST(date_value AS char)

This answers a slightly different question, but the question title seems ambiguous enough that this might help someone searching.

preparedStatement.setNull(index, java.sql.Types.NULL);

that should work for any type. Though in some cases failure happens on the server-side, like: for SQL:

COALESCE(?, CURRENT_TIMESTAMP)

Oracle 18XE fails with the wrong type: expected DATE, got STRING -- that is a perfectly valid failure;

Bottom line: it is good to know the type if you call .setNull()

To get an access token: facebook Graph API Explorer

You can customize specific access permissions, basic permissions are included by default.

       var mode = [];
                $("input[name='mode[]']:checked").each(function(i) {
                    mode.push($(this).val());
                })
 if(mode.length == 0)
                {
                   alert('Please select mode!')
                };

Try this

<script type="text/javascript">
    function AddItem()
    {
        // Create an Option object       
        var opt = document.createElement("option");        

        // Assign text and value to Option object
        opt.text = "New Value";
        opt.value = "New Value";

        // Add an Option object to Drop Down List Box
        document.getElementById('<%=DropDownList.ClientID%>').options.add(opt);
    }
<script />

The Value will append to the drop down list.

Here are the high-level differences:

Forking

Pros

• Keeps branches separated by user
• Reduces clutter in the primary repository
• Your team process reflects the external contributor process

Cons

• Makes it more difficult to see all of the branches that are active (or inactive, for that matter)
• Collaborating on a branch is trickier (the fork owner needs to add the person as a collaborator)
• You need to understand the concept of multiple remotes in Git
  • Requires additional mental bookkeeping
  • This will make the workflow more difficult for people who aren't super comfortable with Git

Branching

Pros

• Keeps all of the work being done around a project in one place
• All collaborators can push to the same branch to collaborate on it
• There's only one Git remote to deal with

Cons

• Branches that get abandoned can pile up more easily
• Your team contribution process doesn't match the external contributor process
• You need to add team members as contributors before they can branch

You can find a lot of historical data here: https://www.quandl.com/data/BCHARTS-Bitcoin-Charts-Exchange-Rate-Data

For VB.NET, you can place the following before your web request:

Const _Tls12 As SslProtocols = DirectCast(&HC00, SslProtocols)
Const Tls12 As SecurityProtocolType = DirectCast(_Tls12, SecurityProtocolType)
ServicePointManager.SecurityProtocol = Tls12

This solved my security issue on .NET 3.5.

The first one

f = lambda x: x*x
[f(x) for x in range(10)]

runs f() for each value in the range so it does f(x) for each value

the second one

[lambda x: x*x for x in range(10)]

runs the lambda for each value in the list, so it generates all of those functions.

HTML:

<a href="#" class="delete" data-confirm="Are you sure to delete this item?">Delete</a>

Using jQuery:

$('.delete').on("click", function (e) {
    e.preventDefault();

    var choice = confirm($(this).attr('data-confirm'));

    if (choice) {
        window.location.href = $(this).attr('href');
    }
});

Suggest do this in your code-behind before sending down to SQL Server.

 int userVal = int.Parse(txtboxname.Text);

Perhaps try to parse and optionally let the user know.

int? userVal;
if (int.TryParse(txtboxname.Text, out userVal) 
{
  DoSomething(userVal.Value);
}
else
{ MessageBox.Show("Hey, we need an int over here.");   }

The exception you note means that you're not including the value in the call to the stored proc. Try setting a debugger breakpoint in your code at the time you call down into the code that builds the call to SQL Server.

Ensure you're actually attaching the parameter to the SqlCommand.

using (SqlConnection conn = new SqlConnection(connString))
{
    SqlCommand cmd = new SqlCommand(sql, conn);
    cmd.Parameters.Add("@ParamName", SqlDbType.Int);
    cmd.Parameters["@ParamName"].Value = newName;        
    conn.Open();
    string someReturn = (string)cmd.ExecuteScalar();        
}

Perhaps fire up SQL Profiler on your database to inspect the SQL statement being sent/executed.

With the constructor:

// create a vector with 20 integer elements
std::vector<int> arr(20);

for(int x = 0; x < 20; ++x)
   arr[x] = x;

Very simple methods Just go to the terminal and the type following

rails g devise:controllers users //This will create devise controllers in controllers/users folder

Next to use custom views

rails g devise:views users //This will create devise views in views/users folder

now in your route.rb file

devise_for :users, controllers: {
           :sessions => "users/sessions",
           :registrations => "users/registrations" }

You can add other controllers too. This will make devise to use controllers in users folder and views in users folder.

Now you can customize your views as your desire and add your logic to controllers in controllers/users folder. Enjoy !

var str = "123, 124, 234,252";
var arr = str.split(",");
for(var i=0;i<arr.length;i++) {
    arr[i] = ++arr[i];
}

You don't need to parse the string, it's defined as a string already.

Just do:

    private static String getStringInput (String prompt) {
     String input = EZJ.getUserInput(prompt);
     return input;
    }

This is impossible as you cannot return from an asynchronous call inside a synchronous method.

In this case you need to pass a callback to foo that will receive the return value

function foo(address, fn){
  geocoder.geocode( { 'address': address}, function(results, status) {
     fn(results[0].geometry.location); 
  });
}

foo("address", function(location){
  alert(location); // this is where you get the return value
});

The thing is, if an inner function call is asynchronous, then all the functions 'wrapping' this call must also be asynchronous in order to 'return' a response.

If you have a lot of callbacks you might consider taking the plunge and use a promise library like Q.

For File Open only, the syntax is

 ,"one\n
 two",...

The critical thing is that there is no space after the first ",". Normally spaces are fine, and trimmed if the string is not quoted. But otherwise nasty. Took me a while to figure that out.

It does not seem to matter if the line is ended \n or \c\n.

Make sure you expand the formula bar so you can actually see the text in the cell (got me after a long day...)

Now of course, File Open will not support UTF-8 Properly (unless one uses tricks).

Excel > Data > Get External Data > From Text

Can be set into UTF-8 mode (it is way down the list of fonts). However, in that case the new lines do not seem to work and I know no way to fix that.

(One might thing that after 30 years MS would get this stuff right.)

I think it's a matter of preference. I personally use:

if($something){
       $execute_something;
}

Add a try/catch block, if the transaction succeeds it will commit the changes, if the transaction fails the transaction is rolled back:

BEGIN TRANSACTION [Tran1]

  BEGIN TRY

      INSERT INTO [Test].[dbo].[T1] ([Title], [AVG])
      VALUES ('Tidd130', 130), ('Tidd230', 230)

      UPDATE [Test].[dbo].[T1]
      SET [Title] = N'az2' ,[AVG] = 1
      WHERE [dbo].[T1].[Title] = N'az'

      COMMIT TRANSACTION [Tran1]

  END TRY

  BEGIN CATCH

      ROLLBACK TRANSACTION [Tran1]

  END CATCH  

For Windows, you can use winsound. It's built in

import winsound

winsound.PlaySound('sound.wav', winsound.SND_FILENAME)

You should be able to use ossaudiodev for linux:

from wave import open as waveOpen
from ossaudiodev import open as ossOpen
s = waveOpen('tada.wav','rb')
(nc,sw,fr,nf,comptype, compname) = s.getparams( )
dsp = ossOpen('/dev/dsp','w')
try:
  from ossaudiodev import AFMT_S16_NE
except ImportError:
  from sys import byteorder
  if byteorder == "little":
    AFMT_S16_NE = ossaudiodev.AFMT_S16_LE
  else:
    AFMT_S16_NE = ossaudiodev.AFMT_S16_BE
dsp.setparameters(AFMT_S16_NE, nc, fr)
data = s.readframes(nf)
s.close()
dsp.write(data)
dsp.close()

(Credit for ossaudiodev: Bill Dandreta http://mail.python.org/pipermail/python-list/2004-October/288905.html)

I personally find it hard to remember all the modules that needed to be imported. Thus I tend to use a simple method, even though I don't know how its performance is compared to other answers.

If you just want to flatten nested lists, then the following will do the job:

def flatten(lst):
    for item in lst:
        if isinstance(item, list):
            yield from flatten(item)
        else:
            yield item

# test case:
a =[0, [], "fun", [1, 2, 3], [4, [5], 6], 3, [7], [8, 9]]
list(flatten(a))
# output 
# [0, 'fun', 1, 2, 3, 4, 5, 6, 3, 7, 8, 9]

However, if you want to flatten a list of iterables (list and/or tuples), it can also do the job with a slight modification:

from collections.abc import Iterable
def flatten(lst):
    for item in lst:
        if isinstance(item,Iterable) and not isinstance(item,str):
            yield from flatten(item)
        else:
            yield item

# test case:
a =[0, [], "fun", (1, 2, 3), [4, [5], (6)], 3, [7], [8, 9]]
list(flatten(a))
# output: 
# [0, 'fun', 1, 2, 3, 4, 5, 6, 3, 7, 8, 9]

Setting vars in /etc/environment also worked for me in Ubuntu. As of 12.04, variables in /etc/environment are loaded for cron.

Typical Java programs compile into .jar files, which can be executed like .exe files provided the target machine has Java installed and that Java is in its PATH. From Eclipse you use the Export menu item from the File menu.

I have not played with 3D yet, but I know a good place for ressources on 3D for HTML5.

http://www.html5rocks.com/en/gaming

And here is a tutorial on how to create your 3D models with the Three.js Framework.

There is a much simpler way to do it using seaborn:

import seaborn as sns
from scipy.stats import norm

data = norm.rvs(5,0.4,size=1000) # you can use a pandas series or a list if you want

sns.distplot(data)
plt.show()

output:

Make use of using the Color and Backcolor Properties to write Expressions for your query. Add the following to the expression option for the color property that you want to cater for)

Example

=iif(fields!column.value = "Approved", "Green","<other color>")

iif needs 3 values, first the relating Column, then the second is to handle the True and the third is to handle the False for the iif statement

ls -l $file | awk '{print $6}'

assuming that ls command reports filesize at column #6

No need for array. Just use something like this:

Sub ARRAYER()

    Dim Rng As Range
    Dim Number_of_Sims As Long
    Dim i As Long
    Number_of_Sims = 10

    Set Rng = Range("C4:G4")
    For i = 1 To Number_of_Sims
       Rng.Offset(i, 0).Value = Rng.Value
       Worksheets("Sheetname").Calculate   'replacing Sheetname with name of your sheet
    Next

End Sub

I put together start to finish code of a hypothetical experiment with ten measurement replicated three times. Just for fun with the help of other stackoverflowers. Thank you... Obviously loops are an option as applycan be used but I like to see what happens.

#Create fake data
x <-rep(1:10, each =3)
y <- rnorm(30, mean=4,sd=1)

#Loop to get standard deviation from data
sd.y = NULL
for(i in 1:10){
  sd.y[i] <- sd(y[(1+(i-1)*3):(3+(i-1)*3)])
}
sd.y<-rep(sd.y,each = 3)

#Loop to get mean from data
mean.y = NULL
for(i in 1:10){
  mean.y[i] <- mean(y[(1+(i-1)*3):(3+(i-1)*3)])
}
mean.y<-rep(mean.y,each = 3)

#Put together the data to view it so far
data <- cbind(x, y, mean.y, sd.y)

#Make an empty matrix to fill with shrunk data
data.1 = matrix(data = NA, nrow=10, ncol = 4)
colnames(data.1) <- c("X","Y","MEAN","SD")

#Loop to put data into shrunk format
for(i in 1:10){
  data.1[i,] <- data[(1+(i-1)*3),]
}

#Create atomic vectors for arrows
x <- data.1[,1]
mean.exp <- data.1[,3]
sd.exp <- data.1[,4]

#Plot the data
plot(x, mean.exp, ylim = range(c(mean.exp-sd.exp,mean.exp+sd.exp)))
abline(h = 4)
arrows(x, mean.exp-sd.exp, x, mean.exp+sd.exp, length=0.05, angle=90, code=3)

The ngRoute module is no longer part of the core angular.js file. If you are continuing to use $routeProvider then you will now need to include angular-route.js in your HTML:

<script src="angular.js">
<script src="angular-route.js">

API Reference

You also have to add ngRoute as a dependency for your application:

var app = angular.module('MyApp', ['ngRoute', ...]);

If instead you are planning on using angular-ui-router or the like then just remove the $routeProvider dependency from your module .config() and substitute it with the relevant provider of choice (e.g. $stateProvider). You would then use the ui.router dependency:

var app = angular.module('MyApp', ['ui.router', ...]);

        Note:
        1) Both ++ and * have same precedence(priority), so the associativity comes into picture.
        2) in this case Associativity is from **Right-Left**

        important table to remember in case of pointers and arrays: 

        operators           precedence        associativity

    1)  () , []                1               left-right
    2)  *  , identifier        2               right-left
    3)  <data type>            3               ----------

        let me give an example, this might help;

        char **str;
        str = (char **)malloc(sizeof(char*)*2); // allocate mem for 2 char*
        str[0]=(char *)malloc(sizeof(char)*10); // allocate mem for 10 char
        str[1]=(char *)malloc(sizeof(char)*10); // allocate mem for 10 char

        strcpy(str[0],"abcd");  // assigning value
        strcpy(str[1],"efgh");  // assigning value

        while(*str)
        {
            cout<<*str<<endl;   // printing the string
            *str++;             // incrementing the address(pointer)
                                // check above about the prcedence and associativity
        }
        free(str[0]);
        free(str[1]);
        free(str);

I use this to convert char to string (an example) :

char c = 'A';
char str1[2] = {c , '\0'};
char str2[5] = "";
strcpy(str2,str1);

I had this issue and it took me for a while to figure out how to fix that.

My case is slightly different. My MySQL server is of version 5.1.x. And somehow I upgraded my MySQL-python from 1.2.3 to 1.2.5. And I kept getting this issue since then event I added the following soft link.

libmysqlclient.18.dylib -> /usr/local/mysql/lib/libmysqlclient.18.dylib

It turns out that for MySQL 5.1.x there is no libmysqlclient.18.dylib, but only libmysqlclient.16.dylib. You can fix this issue either by downgrade your MySQL-python to 1.2.3 or upgrade your MySQL server to 5.6.x (I haven't tried 5.5.x.)

I downgraded the library to 1.2.3 since upgrading MySQL is not an option for me.

For Asp.Net core you better use

<partial name="_MyPartialView" model="MyModel" />

So for example

@foreach (var item in Model)
{
   <partial name="_MyItemView" model="item" />
}

Since Java 7 this is very easy and intuitive to do.

List<String> fileContent = new ArrayList<>(Files.readAllLines(FILE_PATH, StandardCharsets.UTF_8));

for (int i = 0; i < fileContent.size(); i++) {
    if (fileContent.get(i).equals("old line")) {
        fileContent.set(i, "new line");
        break;
    }
}

Files.write(FILE_PATH, fileContent, StandardCharsets.UTF_8);

Basically you read the whole file to a List, edit the list and finally write the list back to file.

FILE_PATH represents the Path of the file.

I use the IntelliJ one, because I'm mostly concerned with IntelliJ flagging things that might produce a NPE. I agree that it's frustrating not having a standard annotation in the JDK. There's talk of adding it, it might make it into Java 7. In which case there will be one more to choose from!

The problem is in the line before the one that throws the warning. When you create df_2 that's where you're creating a copy of a slice of a dataframe. Instead, when you create df_2, use .copy() and you won't get that warning later on.

df_2 = df[df['B'] == 'b.2'].copy()

Acepted solution implemented in PyQt5

import sys
from PyQt5.QtWidgets import QApplication, QDialog, QFormLayout
from PyQt5.QtWidgets import (QPushButton, QLineEdit)

A JIT compiler runs after the program has started and compiles the code (usually bytecode or some kind of VM instructions) on the fly (or just-in-time, as it's called) into a form that's usually faster, typically the host CPU's native instruction set. A JIT has access to dynamic runtime information whereas a standard compiler doesn't and can make better optimizations like inlining functions that are used frequently.

This is in contrast to a traditional compiler that compiles all the code to machine language before the program is first run.

To paraphrase, conventional compilers build the whole program as an EXE file BEFORE the first time you run it. For newer style programs, an assembly is generated with pseudocode (p-code). Only AFTER you execute the program on the OS (e.g., by double-clicking on its icon) will the (JIT) compiler kick in and generate machine code (m-code) that the Intel-based processor or whatever will understand.

To answer to your second question. You can just hit the IP address of the machine that your flask app is running, e.g. 192.168.1.100 in a browser on different machine on the same network and you are there. Though, you will not be able to access it if you are on a different network. Firewalls or VLans can cause you problems with reaching your application. If that computer has a public IP, then you can hit that IP from anywhere on the planet and you will be able to reach the app. Usually this might impose some configuration, since most of the public servers are behind some sort of router or firewall.

This looks like a Json array list.Therefore its best to use ArrayList to handle the data. In your api end point add array list like this

 @GET("places/")
Call<ArrayList<Place>> getNearbyPlaces(@Query("latitude") String latitude, @Query("longitude") String longitude);

You cannot run an ipa file in the simulator because the ipa file is compiled for a phone's ARM architecture, not the simulator's x86 architecture.

However, you can extract an app installed in a local simulator, send it to someone else, and have them copy it to the simulator on their machine.

In terminal, type:

open ~/Library/Application\ Support/iPhone\ Simulator/*/Applications

This will open all the applications folders of all the simulators you have installed. Each of the applications will be in a folder with a random hexadecimal name. You can work out which is your application by looking inside each of them. Once you have found out which one you want, right click it and choose "Compress ..." and it will make a zip file that you can easily copy to another computer and unzip to a similar location.

Git 1.8.2 features a new option ,--remote, that will enable exactly this behavior. Running

git submodule update --rebase --remote

will fetch the latest changes from upstream in each submodule, rebase them, and check out the latest revision of the submodule. As the documentation puts it:

--remote

This option is only valid for the update command. Instead of using the superproject’s recorded SHA-1 to update the submodule, use the status of the submodule’s remote-tracking branch.

This is equivalent to running git pull in each submodule, which is generally exactly what you want.

You should be importing

#import "SCLAlertView-Swift.h"

The & means that the function accepts the address (or reference) to a variable, instead of the value of the variable.

For example, note the difference between this:

void af(int& g)
{
    g++;
    cout<<g;
}

int main()
{
    int g = 123;
    cout << g;
    af(g);
    cout << g;
    return 0;
}

And this (without the &):

void af(int g)
{
    g++;
    cout<<g;
}

int main()
{
    int g = 123;
    cout << g;
    af(g);
    cout << g;
    return 0;
}

Assuming you are talking about the ActionEvent class, then there is a big difference between the two methods.

getActionCommand() gives you a String representing the action command. The value is component specific; for a JButton you have the option to set the value with setActionCommand(String command) but for a JTextField if you don't set this, it will automatically give you the value of the text field. According to the javadoc this is for compatability with java.awt.TextField.

getSource() is specified by the EventObject class that ActionEvent is a child of (via java.awt.AWTEvent). This gives you a reference to the object that the event came from.

Edit:

Here is a example. There are two fields, one has an action command explicitly set, the other doesn't. Type some text into each then press enter.

public class Events implements ActionListener {

  private static JFrame frame; 

  public static void main(String[] args) {

    frame = new JFrame("JTextField events");
    frame.getContentPane().setLayout(new FlowLayout());

    JTextField field1 = new JTextField(10);
    field1.addActionListener(new Events());
    frame.getContentPane().add(new JLabel("Field with no action command set"));
    frame.getContentPane().add(field1);

    JTextField field2 = new JTextField(10);
    field2.addActionListener(new Events());
    field2.setActionCommand("my action command");
    frame.getContentPane().add(new JLabel("Field with an action command set"));
    frame.getContentPane().add(field2);


    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    frame.setSize(220, 150);
    frame.setResizable(false);
    frame.setVisible(true);
  }

  @Override
  public void actionPerformed(ActionEvent evt) {
    String cmd = evt.getActionCommand();
    JOptionPane.showMessageDialog(frame, "Command: " + cmd);
  }

}

You could just add one needed external jar file to the project. Go to your project-->java build path-->libraries, add external JARS.Then add your downloaded file from the formal website. My default name is commons-codec-1.10.jar

Probably the easiest way would be use this app Hosts Editor . You need to have root

The top ranked answer to this question suggests using the readLine() method to take in user input from the command line. However, I want to note that you need to use the ! operator when calling this method to return a string instead of an optional:

var response = readLine()!

Setting your provisioning profile moved. It confounded me for a while until I found it also.

1. Select your project file (to open target)
2. Click on the "Build Settings" tab
3. Scroll down to "Code Signing" and see the new "Provisioning Profile" section there.

Pika is a CDN that takes care of providing module versions of popular packages

<script type='module'>
    import * as $ from 'https://cdn.skypack.dev/jquery';

    // use it!
    $('#myDev').on('click', alert);
</script>

Skypack is Pika, so you could also use: import * as $ from 'https://cdn.pika.dev/jquery@^3.5.1';

I think the reason that this is happening could be because TextBox1 is scoping to the VBA module and its associated sheet, while Range is scoping to the "Active Sheet".

EDIT

It looks like you may be able to use the GetObject function to pull the textbox from the workbook.

This is also another good Home Screen script that support iphone/ipad, Mobile Safari, Android, Blackberry touch smartphones and Playbook .

Just in case commands in previous answers doesn't work, Try this: dat.dropna(subset=['x'], inplace = True)

I was looking for a solution to this as well. In my case, it was pretty easy.

I have a list menu with all the links:

<ul>
<li><a href="#one">one</a></li>
<li><a href="#two">two</a></li>
<li><a href="#three">three</a></li>
<li><a href="#four">four</a></li>
</ul>

And below that the headings where it should go to.

<h3>one</h3>
<p>text here</p>

<h3>two</h3>
<p>text here</p>

<h3>three</h3>
<p>text here</p>

<h3>four</h3>
<p>text here</p>

Now because I have a fixed menu at the top of my page I can't just make it go to my tag because that would be behind the menu.

Instead, I put a span tag inside my tag with the proper id.

<h3><span id="one"></span>one</h3>

Now use 2 lines of CSS to position them properly.

h3{ position:relative; }
h3 span{ position:absolute; top:-200px;}

Change the top value to match the height of your fixed header (or more). Now I assume this would work with other elements as well.

document.getElementById('Id').value='new value';

https://developer.mozilla.org/en-US/docs/Web/API/document.getElementById

You could do it with a static import and a helper class

nb the generification of this class could probably be improved

public class Lists {

   private Lists() { } // can't be instantiated

   public static List<T> join(List<T>... lists) {
      List<T> result = new ArrayList<T>();
      for(List<T> list : lists) {
         result.addAll(list);
      }
      return results;
   }

}

Then you can do things like

import static Lists.join;
List<T> result = join(list1, list2, list3, list4);

Well, the Console Standard (as of commit ef88ec7a39fdfe79481d7d8f2159e4a323e89648) currently calls for console.dir to apply generic JavaScript object formatting before passing it to Printer (a spec-level operation), but for a single-argument console.log call, the spec ends up passing the JavaScript object directly to Printer.

Since the spec actually leaves almost everything about the Printer operation to the implementation, it's left to their discretion what type of formatting to use for console.log().

I think that you are after this:

SELECT image_id
FROM list
WHERE (style_id, style_value) IN ((24,'red'),(25,'big'),(27,'round'))
GROUP BY image_id
HAVING count(distinct style_id, style_value)=3

You can't use AND, because values can't be 24 red and 25 big and 27 round at the same time in the same row, but you need to check the presence of style_id, style_value in multiple rows, under the same image_id.

In this query I'm using IN (that, in this particular example, is equivalent to an OR), and I am counting the distinct rows that match. If 3 distinct rows match, it means that all 3 attributes are present for that image_id, and my query will return it.

var ItemSchema = new Schema({
    name : { type: String }
});

ItemSchema.set('timestamps', true); // this will add createdAt and updatedAt timestamps

Docs: https://mongoosejs.com/docs/guide.html#timestamps

Keep in mind the second parameter to @Html.HiddenFor will only be used to set the value when it can't find route or model data matching the field. Darin is correct, use view model.

Try this:

/\d{3}-(?:(apple|banana)-)?\d{3}/

As posted by 'Dan' in a similar thread, there is a possible fix if you're not using a sprite:

How do I make background-size work in IE?

filter: progid:DXImageTransform.Microsoft.AlphaImageLoader(
src='images/logo.gif',
sizingMethod='scale');

-ms-filter: "progid:DXImageTransform.Microsoft.AlphaImageLoader(
src='images/logo.gif',
sizingMethod='scale')";

However, this scales the entire image to fit in the allocated area. So if your using a sprite, this may cause issues.

Caution
The filter has a flaw, any links inside the allocated area are no longer clickable.

To set a class completely, instead of adding one or removing one, use this:

$(this).attr("class","newclass");

Advantage of this is that you'll remove any class that might be set in there and reset it to how you like. At least this worked for me in one situation.

$('.some_selector').attr('disabled', true);

Try "eventcreate.exe"

An example:

eventcreate /ID 1 /L APPLICATION /T INFORMATION  /SO MYEVENTSOURCE /D "My first log"

This will create a new event source named MYEVENTSOURCE under APPLICATION event log as INFORMATION event type.

I think this utility is included only from XP onwards.

This article clarifies the question for me and discusses other types of load balancer persistence.

Dave's Thoughts: Load balancer persistence (sticky sessions)

This will work on Snowflake (credit to Darren Gardner):

create temp table ss (id int, val int);
insert into ss (id,val) select 1, 3;
insert into ss (id,val) select 2, null;
insert into ss (id,val) select 3, 5;
insert into ss (id,val) select 4, null;
insert into ss (id,val) select 5, null;
insert into ss (id,val) select 6, 2;

select *
      ,last_value(val ignore nulls) over 
       (order by id rows between unbounded preceding and current row) as val2
  from ss;

I am not really sure about your question (the meaning of "empty table" etc, or how mappedBy and JoinColumn were not working).

I think you were trying to do a bi-directional relationships.

First, you need to decide which side "owns" the relationship. Hibernate is going to setup the relationship base on that side. For example, assume I make the Post side own the relationship (I am simplifying your example, just to keep things in point), the mapping will look like:

(Wish the syntax is correct. I am writing them just by memory. However the idea should be fine)

public class User{
    @OneToMany(fetch=FetchType.LAZY, cascade = CascadeType.ALL, mappedBy="user")
    private List<Post> posts;
}


public class Post {
    @ManyToOne(fetch=FetchType.LAZY)
    @JoinColumn(name="user_id")
    private User user;
}

By doing so, the table for Post will have a column user_id which store the relationship. Hibernate is getting the relationship by the user in Post (Instead of posts in User. You will notice the difference if you have Post's user but missing User's posts).

You have mentioned mappedBy and JoinColumn is not working. However, I believe this is in fact the correct way. Please tell if this approach is not working for you, and give us a bit more info on the problem. I believe the problem is due to something else.

Edit:

Just a bit extra information on the use of mappedBy as it is usually confusing at first. In mappedBy, we put the "property name" in the opposite side of the bidirectional relationship, not table column name.

This can be addressed using the following LINQ expression:

var result = peopleList2.Where(p => !peopleList1.Any(p2 => p2.ID == p.ID));

An alternate way of expressing this via LINQ, which some developers find more readable:

var result = peopleList2.Where(p => peopleList1.All(p2 => p2.ID != p.ID));

Warning: As noted in the comments, these approaches mandate an O(n*m) operation. That may be fine, but could introduce performance issues, and especially if the data set is quite large. If this doesn't satisfy your performance requirements, you may need to evaluate other options. Since the stated requirement is for a solution in LINQ, however, those options aren't explored here. As always, evaluate any approach against the performance requirements your project might have.

@coldmind answer is correct but lacks details.

The 'NOT NULL constraint failed' occurs when something tries to set None to the 'zipcode' property, while it has not been explicitely allowed.

It usually happens when:

1) your field has Null=False by default, so that the value in the database cannot be None (i.e. undefined) when the object is created and saved in the database (this happens after a objects_set.create() call or setting the .zipcode property and doing a .save() call).

For instance, if somewhere in your code an assignement results in:

model.zipcode = None

this error is raised

2) When creating or updating the database, Django is constrained to find a default value to fill the field, because Null=False by default. It does not find any because you haven't defined any. So this error can not only happen during code execution but also when creating the database?

3) Note that the same error would be returned of you define default=None, or if your default value with an incorrect type, for instance default='00000' instead of 00000 for your field (maybe can there be automatic conversion between char and integers, but I would advise against relying on it. Besides, explicit is better than implicit). Most likely an error would also be raised if the default value violates the max_length property, e.g. 123456

So you'll have to define the field by one of the following:

models.IntegerField(_('zipcode'), max_length=5, Null=True,
   blank=True)

models.IntegerField(_('zipcode'), max_length=5, Null=False,
   blank=True, default=00000)

models.IntegerField(_('zipcode'), max_length=5, blank=True,
   default=00000)

and then make a migration (python3 manage.py makemigration ) and then migrate (python3 manage.py migrate).

For safety you can also delete the last failed migration files in <app_name>/migrations/, there are usually named after this pattern:

<NUMBER>_auto_<DATE>_<HOUR>.py

Finally, if you don't set Null=True, make sure that mode.zipcode = None is never done anywhere.

Do you merely want to print the string that way, or do you want that to be the internal representation of the string? If the latter, create it as a raw string by prefixing it with r: r"Hello\tWorld\nHello World".

>>> a = r"Hello\tWorld\nHello World"
>>> a # in the interpreter, this calls repr()
'Hello\\tWorld\\nHello World'
>>> print a
Hello\tWorld\nHello World

Also, \s is not an escape character, except in regular expressions, and then it still has a much different meaning than what you're using it for.

just write "java -d64 -version" or d32 and if you have It installed it will give a response with current version installed

An empty static class is appropriate. Consider using several classes, so that you end up with good groups of related constants, and not one giant Globals.cs file.

Additionally, for some int constants, consider the notation:

[Flags]
enum Foo
{
}

As this allows for treating the values like flags.

one liner remote remove all collections from mongo database

note must use --host, (-h is help for mongo command), and -d is not an option, select the db and command after password.

mongo --host <mongo_host>:<mongo_port> -u <db_user> -p <db_pass> <your_db> --eval "db.dropDatabase()"

Here's an example previously found at androidsnippets.com (the site is currently not maintained anymore).

// Create a new HttpClient and Post Header
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://www.yoursite.com/script.php");

try {
    // Add your data
    List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
    nameValuePairs.add(new BasicNameValuePair("id", "12345"));
    nameValuePairs.add(new BasicNameValuePair("stringdata", "AndDev is Cool!"));
    httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

    // Execute HTTP Post Request
    HttpResponse response = httpclient.execute(httppost);

} catch (ClientProtocolException e) {
    // TODO Auto-generated catch block
} catch (IOException e) {
    // TODO Auto-generated catch block
}

So, you can add your parameters as BasicNameValuePair.

An alternative is to use (Http)URLConnection. See also Using java.net.URLConnection to fire and handle HTTP requests. This is actually the preferred method in newer Android versions (Gingerbread+). See also this blog, this developer doc and Android's HttpURLConnection javadoc.

From Hadoop page,

start-all.sh 

This will startup a Namenode, Datanode, Jobtracker and a Tasktracker on your machine.

start-dfs.sh

This will bring up HDFS with the Namenode running on the machine you ran the command on. On such a machine you would need start-mapred.sh to separately start the job tracker

start-all.sh/stop-all.sh has to be run on the master node

You would use start-all.sh on a single node cluster (i.e. where you would have all the services on the same node.The namenode is also the datanode and is the master node).

In multi-node setup,

You will use start-all.sh on the master node and would start what is necessary on the slaves as well.

Alternatively,

Use start-dfs.sh on the node you want the Namenode to run on. This will bring up HDFS with the Namenode running on the machine you ran the command on and Datanodes on the machines listed in the slaves file.

Use start-mapred.sh on the machine you plan to run the Jobtracker on. This will bring up the Map/Reduce cluster with Jobtracker running on the machine you ran the command on and Tasktrackers running on machines listed in the slaves file.

hadoop-daemon.sh as stated by Tariq is used on each individual node. The master node will not start the services on the slaves.In a single node setup this will act same as start-all.sh.In a multi-node setup you will have to access each node (master as well as slaves) and execute on each of them.

Have a look at this start-all.sh it call config followed by dfs and mapred

With the advent of .NET 4.0 (and higher) with the Stream.CopyTo() methods, I thought I would post an updated approach.

I also think the below version is useful as a clear example of a self-contained class for compressing regular strings to Base64 encoded strings, and vice versa:

public static class StringCompression
{
    /// <summary>
    /// Compresses a string and returns a deflate compressed, Base64 encoded string.
    /// </summary>
    /// <param name="uncompressedString">String to compress</param>
    public static string Compress(string uncompressedString)
    {
        byte[] compressedBytes;

        using (var uncompressedStream = new MemoryStream(Encoding.UTF8.GetBytes(uncompressedString)))
        {
            using (var compressedStream = new MemoryStream())
            { 
                // setting the leaveOpen parameter to true to ensure that compressedStream will not be closed when compressorStream is disposed
                // this allows compressorStream to close and flush its buffers to compressedStream and guarantees that compressedStream.ToArray() can be called afterward
                // although MSDN documentation states that ToArray() can be called on a closed MemoryStream, I don't want to rely on that very odd behavior should it ever change
                using (var compressorStream = new DeflateStream(compressedStream, CompressionLevel.Fastest, true))
                {
                    uncompressedStream.CopyTo(compressorStream);
                }

                // call compressedStream.ToArray() after the enclosing DeflateStream has closed and flushed its buffer to compressedStream
                compressedBytes = compressedStream.ToArray();
            }
        }

        return Convert.ToBase64String(compressedBytes);
    }

    /// <summary>
    /// Decompresses a deflate compressed, Base64 encoded string and returns an uncompressed string.
    /// </summary>
    /// <param name="compressedString">String to decompress.</param>
    public static string Decompress(string compressedString)
    {
        byte[] decompressedBytes;

        var compressedStream = new MemoryStream(Convert.FromBase64String(compressedString));

        using (var decompressorStream = new DeflateStream(compressedStream, CompressionMode.Decompress))
        {
            using (var decompressedStream = new MemoryStream())
            {
                decompressorStream.CopyTo(decompressedStream);

                decompressedBytes = decompressedStream.ToArray();
            }
        }

        return Encoding.UTF8.GetString(decompressedBytes);
    }

Here’s another approach using the extension methods technique to extend the String class to add string compression and decompression. You can drop the class below into an existing project and then use thusly:

var uncompressedString = "Hello World!";
var compressedString = uncompressedString.Compress();

and

var decompressedString = compressedString.Decompress();

To wit:

public static class Extensions
{
    /// <summary>
    /// Compresses a string and returns a deflate compressed, Base64 encoded string.
    /// </summary>
    /// <param name="uncompressedString">String to compress</param>
    public static string Compress(this string uncompressedString)
    {
        byte[] compressedBytes;

        using (var uncompressedStream = new MemoryStream(Encoding.UTF8.GetBytes(uncompressedString)))
        {
            using (var compressedStream = new MemoryStream())
            { 
                // setting the leaveOpen parameter to true to ensure that compressedStream will not be closed when compressorStream is disposed
                // this allows compressorStream to close and flush its buffers to compressedStream and guarantees that compressedStream.ToArray() can be called afterward
                // although MSDN documentation states that ToArray() can be called on a closed MemoryStream, I don't want to rely on that very odd behavior should it ever change
                using (var compressorStream = new DeflateStream(compressedStream, CompressionLevel.Fastest, true))
                {
                    uncompressedStream.CopyTo(compressorStream);
                }

                // call compressedStream.ToArray() after the enclosing DeflateStream has closed and flushed its buffer to compressedStream
                compressedBytes = compressedStream.ToArray();
            }
        }

        return Convert.ToBase64String(compressedBytes);
    }

    /// <summary>
    /// Decompresses a deflate compressed, Base64 encoded string and returns an uncompressed string.
    /// </summary>
    /// <param name="compressedString">String to decompress.</param>
    public static string Decompress(this string compressedString)
    {
        byte[] decompressedBytes;

        var compressedStream = new MemoryStream(Convert.FromBase64String(compressedString));

        using (var decompressorStream = new DeflateStream(compressedStream, CompressionMode.Decompress))
        {
            using (var decompressedStream = new MemoryStream())
            {
                decompressorStream.CopyTo(decompressedStream);

                decompressedBytes = decompressedStream.ToArray();
            }
        }

        return Encoding.UTF8.GetString(decompressedBytes);
    }

A nice and easy way for those people who always forget the command axhline is the following

plt.plot(x, [y]*len(x))

In your case xs = x and y = 40. If len(x) is large, then this becomes inefficient and you should really use axhline.

I've found that you can move div elements to the next line simply by setting the property Display: block;

On each div.

You Can try this:

function formatDate(userDOB) {_x000D_
  const dob = new Date(userDOB);_x000D_
_x000D_
  const monthNames = [_x000D_
    'January', 'February', 'March', 'April', 'May', 'June', 'July',_x000D_
     'August', 'September', 'October', 'November', 'December'_x000D_
  ];_x000D_
_x000D_
  const day = dob.getDate();_x000D_
  const monthIndex = dob.getMonth();_x000D_
  const year = dob.getFullYear();_x000D_
_x000D_
  // return day + ' ' + monthNames[monthIndex] + ' ' + year;_x000D_
  return `${day} ${monthNames[monthIndex]} ${year}`;_x000D_
}_x000D_
_x000D_
console.log(formatDate('1982-08-10'));

You can do Edit, Find in Files (or Ctrl+Shift+F - default key binding, Cmd+Shift+F on MacOS) to search the Currently open Folder.

There is an ellipsis on the dialog where you can include/exclude files, and options in the search box for matching case/word and using Regex.

This is a common issue if the Zookeeper server is not running or no longer running (i.e. it crashed after you started it).

So first, check that you have the Zookeeper server running. A simple way to check is grep the running processes:

# ps -ef | grep zookeeper

(run this a couple of times to see if the same process ID is still there. its possible it keep restarting with a new process ID. Alternatively you can use 'systemctl status zookeeper' if your Linux distro support systemd)

You should see the process running as a java process:

# ps -ef | grep zookeeper
root       492     0  0 00:01 pts/1    00:00:00 java -Dzookeeper.log.dir=. -Dzookeeper.root.logger=INFO,CONSOLE -cp /root/zookeeper-3.5.0-alpha/bin/../build/classes:/root/zookeeper-3.5.0-alpha/bin/../build/lib/*.jar:/root/zookeeper-3.5.0-alpha/bin/../lib/slf4j-log4j12-1.7.5.jar:/root/zookeeper-3.5.0-alpha/bin/../lib/slf4j-api-1.7.5.jar:/root/zookeeper-3.5.0-alpha/bin/../lib/servlet-api-2.5-20081211.jar:/root/zookeeper-3.5.0-alpha/bin/../lib/netty-3.7.0.Final.jar:/root/zookeeper-3.5.0-alpha/bin/../lib/log4j-1.2.16.jar:/root/zookeeper-3.5.0-alpha/bin/../lib/jline-2.11.jar:/root/zookeeper-3.5.0-alpha/bin/../lib/jetty-util-6.1.26.jar:/root/zookeeper-3.5.0-alpha/bin/../lib/jetty-6.1.26.jar:/root/zookeeper-3.5.0-alpha/bin/../lib/javacc.jar:/root/zookeeper-3.5.0-alpha/bin/../lib/jackson-mapper-asl-1.9.11.jar:/root/zookeeper-3.5.0-alpha/bin/../lib/jackson-core-asl-1.9.11.jar:/root/zookeeper-3.5.0-alpha/bin/../lib/commons-cli-1.2.jar:/root/zookeeper-3.5.0-alpha/bin/../zookeeper-3.5.0-alpha.jar:/root/zookeeper-3.5.0-alpha/bin/../src/java/lib/*.jar:/root/zookeeper-3.5.0-alpha/bin/../conf: -Xmx1000m -Xmx1000m -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.local.only=false org.apache.zookeeper.server.quorum.QuorumPeerMain /root/zookeeper-3.5.0-alpha/bin/../conf/zoo.cfg

If its not there, then there's likely something in the zookeeper log file indicating the issue.

To find the zookeeper log file, you should first figure out where its configured for logging. In my case I have zookeeper installed under my root directory (not suggesting you install it there):

[root@centos6_zookeeper conf]# pwd
/root/zookeeper-3.5.0-alpha/conf

And you can find the log setting in this file:

[root@centos6_zookeeper conf]# grep "zookeeper.log" log4j.properties 
zookeeper.log.dir=/var/log
zookeeper.log.file=zookeeper.log
zookeeper.log.threshold=INFO
zookeeper.log.maxfilesize=256MB
zookeeper.log.maxbackupindex=20

So Zookeeper is configured to log under /var/log.

Then there's usually a zookeeper.log and/or zookeeper.out file which should indicate your startup error.

For a API v3 solution, refer to:

http://blog.enbake.com/draw-circle-with-google-maps-api-v3

It creates circle around points and then show markers within and out of the range with different colors. They also calculate dynamic radius but in your case radius is fixed so may be less work.

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

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

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

Here are some example matches and the associated replacement output:

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

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

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

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

Update based on comment

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

Preserving your original regex you can use:

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

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

Example matches:

It depends on the output you expect.

A cross join matches all rows in one table to all rows in another table. An inner join matches on a field or fields. If you have one table with 10 rows and another with 10 rows then the two joins will behave differently.

The cross join will have 100 rows returned and they won't be related, just what is called a Cartesian product. The inner join will match records to each other. Assuming one has a primary key and that is a foreign key in the other you would get 10 rows returned.

A cross join has limited general utility, but exists for completeness and describes the result of joining tables with no relations added to the query. You might use a cross join to make lists of combinations of words or something similar. An inner join on the other hand is the most common join.

Simple solution:

# touch filename

will do all OK.

If you are using six, you can try this, by which utilizing the latest Python 3 API and can run in both Python 2/3:

import six

if six.PY2:
    # FileNotFoundError is only available since Python 3.3
    FileNotFoundError = IOError
    from io import open

fname = 'index.rst'
try:
    with open(fname, "rt", encoding="utf-8") as f:
        pass
        # do_something_with_f ...
except FileNotFoundError:
    print('Oops.')

And, Python 2 support abandon is just deleting everything related to six.

Add /Q for quiet mode and it should remove the prompt.

Java 8 introduces the Instant.ofEpochSecond utility method for creating an Instant from a Unix timestamp, this can then be converted into a ZonedDateTime and finally formatted, e.g.:

final DateTimeFormatter formatter = 
    DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss");

final long unixTime = 1372339860;
final String formattedDtm = Instant.ofEpochSecond(unixTime)
        .atZone(ZoneId.of("GMT-4"))
        .format(formatter);

System.out.println(formattedDtm);   // => '2013-06-27 09:31:00'

I thought this might be useful for people who are using Java 8.

I know you said you didn't want to catch an exception. But, because catching an exception is more reliable, I will go ahead and post this answer.

public static bool IsBase64(this string base64String) {
     // Credit: oybek https://stackoverflow.com/users/794764/oybek
     if (string.IsNullOrEmpty(base64String) || base64String.Length % 4 != 0
        || base64String.Contains(" ") || base64String.Contains("\t") || base64String.Contains("\r") || base64String.Contains("\n"))
        return false;

     try{
         Convert.FromBase64String(base64String);
         return true;
     }
     catch(Exception exception){
     // Handle the exception
     }
     return false;
}

Update: I've updated the condition thanks to oybek to further improve reliability.

Using Linux Top command

top -H -p (process id)

you could get process id of one program by this method :

ps aux | grep (your program name)

for example :

ps aux | grep user.py

Persist should be called only on new entities, while merge is meant to reattach detached entities.

If you're using the assigned generator, using merge instead of persist can cause a redundant SQL statement.

Also, calling merge for managed entities is also a mistake since managed entities are automatically managed by Hibernate, and their state is synchronized with the database record by the dirty checking mechanism upon flushing the Persistence Context.

All this tricks just look (more or less) as local functions, but they don't work like that. In a local function you can use local variables of it's super functions. It's kind of semi-globals. Non of these tricks can do that. The closest is the lambda trick from c++0x, but it's closure is bound in definition time, not the use time.

If you want listen an event (i.e OnClick) on an input with "demo" id, you can use:

new Vue({
  el: '#demo',
  data: {
    n: 0
  },
  methods: {
   onClick: function (e) {
     console.log(e.target.tagName) // "A"
     console.log(e.targetVM === this) // true
  }
 }
})

I faced the same issue but the reason was none of the ones listed above. I created a task, created a scope inside the task and asked the container to obtain a service. That worked fine but then I used a second service inside the task and I forgot to also asked for it to the new scope. Because of that, the 2nd service was using a DbContext that was already disposed.

Task task = Task.Run(() =>
    {
        using (var scope = serviceScopeFactory.CreateScope())
        {
            var otherOfferService = scope.ServiceProvider.GetService<IOfferService>();
            // everything was ok here. then I did: 
            productService.DoSomething(); // (from the main scope) and this failed because the db context associated to that service was already disposed.
            ...
        }
    }

I should have done this:

var otherProductService = scope.ServiceProvider.GetService<IProductService>();
otherProductService.DoSomething();

Small change to sam yi's answer (for better readability):

select top 1000 TableID
into #ControlTable 
from dbo.table
where StatusID = 7

declare @TableID int

while exists (select * from #ControlTable)
begin

    select @TableID = (select top 1 TableID
                       from #ControlTable
                       order by TableID asc)

    -- Do something with your TableID

    delete #ControlTable
    where TableID = @TableID

end

drop table #ControlTable

This is a function i used in the past for substracting a date from another one related with your question, my principe was to get how many days, hours minutes and seconds has left until a product has expired :

$expirationDate = strtotime("2015-01-12 20:08:23");
$toDay = strtotime(date('Y-m-d H:i:s'));
$difference = abs($toDay - $expirationDate);
$days = floor($difference / 86400);
$hours = floor(($difference - $days * 86400) / 3600);
$minutes = floor(($difference - $days * 86400 - $hours * 3600) / 60);
$seconds = floor($difference - $days * 86400 - $hours * 3600 - $minutes * 60);

echo "{$days} days {$hours} hours {$minutes} minutes {$seconds} seconds";

Just in case if you are having issues with the code, try putting getSupportActionBar().setTitle(title) inside onResume() of your fragment instead of onCreateView(...) i.e

In MainActivity.java :

public void setActionBarTitle(String title) {
    getSupportActionBar().setTitle(title);
}

In Fragment:

 @Override
 public void onResume(){
     super.onResume();
     ((MainActivity) getActivity()).setActionBarTitle("Your Title");
 }

If you don't want to use the KnockoutValidation library you can write your own. Here's an example for a Mandatory field.

Add a javascript class with all you KO extensions or extenders, and add the following:

ko.extenders.required = function (target, overrideMessage) {
    //add some sub-observables to our observable
    target.hasError = ko.observable();
    target.validationMessage = ko.observable();

    //define a function to do validation
    function validate(newValue) {
    target.hasError(newValue ? false : true);
    target.validationMessage(newValue ? "" : overrideMessage || "This field is required");
    }

    //initial validation
    validate(target());

    //validate whenever the value changes
    target.subscribe(validate);

    //return the original observable
    return target;
};

Then in your viewModel extend you observable by:

self.dateOfPayment: ko.observable().extend({ required: "" }),

There are a number of examples online for this style of validation.

Try this:

document.frames["myiframe"].onload = function(){
   alert("Hello World");
}

If the array is not large, you could just loop and check the string against each substring individually using indexOf(). Alternatively you could construct a regular expression with substrings as alternatives, which may or may not be more efficient.

char c = '1';
int i = (int)(c-'0');

and you can create a static method out of it:

static int ToInt(this char c)
{
    return (int)(c - '0');
}

Use character classes:

^[[:alnum:]]*$

Close Eclipse. Open RemoteSystemsTempFiles folder in Workspace, and clear inside this folder. Again open eclipse and close, warn about .project. Press Ok, then open Eclipse. Solved my problem that.

With the new C++ standard (may need special flags to be enabled on your compiler) you can simply do:

std::vector<int> v { 34,23 };
// or
// std::vector<int> v = { 34,23 };

Or even:

std::vector<int> v(2);
v = { 34,23 };

On compilers that don't support this feature (initializer lists) yet you can emulate this with an array:

int vv[2] = { 12,43 };
std::vector<int> v(&vv[0], &vv[0]+2);

Or, for the case of assignment to an existing vector:

int vv[2] = { 12,43 };
v.assign(&vv[0], &vv[0]+2);

Like James Kanze suggested, it's more robust to have functions that give you the beginning and end of an array:

template <typename T, size_t N>
T* begin(T(&arr)[N]) { return &arr[0]; }
template <typename T, size_t N>
T* end(T(&arr)[N]) { return &arr[0]+N; }

And then you can do this without having to repeat the size all over:

int vv[] = { 12,43 };
std::vector<int> v(begin(vv), end(vv));

Why am I unable to use a string for a newline in write() but I can use it in writelines()?

The idea is the following: if you want to write a single string you can do this with write(). If you have a sequence of strings you can write them all using writelines().

write(arg) expects a string as argument and writes it to the file. If you provide a list of strings, it will raise an exception (by the way, show errors to us!).

writelines(arg) expects an iterable as argument (an iterable object can be a tuple, a list, a string, or an iterator in the most general sense). Each item contained in the iterator is expected to be a string. A tuple of strings is what you provided, so things worked.

The nature of the string(s) does not matter to both of the functions, i.e. they just write to the file whatever you provide them. The interesting part is that writelines() does not add newline characters on its own, so the method name can actually be quite confusing. It actually behaves like an imaginary method called write_all_of_these_strings(sequence).

What follows is an idiomatic way in Python to write a list of strings to a file while keeping each string in its own line:

lines = ['line1', 'line2']
with open('filename.txt', 'w') as f:
    f.write('\n'.join(lines))

This takes care of closing the file for you. The construct '\n'.join(lines) concatenates (connects) the strings in the list lines and uses the character '\n' as glue. It is more efficient than using the + operator.

Starting from the same lines sequence, ending up with the same output, but using writelines():

lines = ['line1', 'line2']
with open('filename.txt', 'w') as f:
    f.writelines("%s\n" % l for l in lines)

This makes use of a generator expression and dynamically creates newline-terminated strings. writelines() iterates over this sequence of strings and writes every item.

Edit: Another point you should be aware of:

write() and readlines() existed before writelines() was introduced. writelines() was introduced later as a counterpart of readlines(), so that one could easily write the file content that was just read via readlines():

outfile.writelines(infile.readlines())

Really, this is the main reason why writelines has such a confusing name. Also, today, we do not really want to use this method anymore. readlines() reads the entire file to the memory of your machine before writelines() starts to write the data. First of all, this may waste time. Why not start writing parts of data while reading other parts? But, most importantly, this approach can be very memory consuming. In an extreme scenario, where the input file is larger than the memory of your machine, this approach won't even work. The solution to this problem is to use iterators only. A working example:

with open('inputfile') as infile:
    with open('outputfile') as outfile:
        for line in infile:
            outfile.write(line)

This reads the input file line by line. As soon as one line is read, this line is written to the output file. Schematically spoken, there always is only one single line in memory (compared to the entire file content being in memory in case of the readlines/writelines approach).

Instance variables or fields, along with static variables, are assigned default values based on the variable type:

• int: 0
• char: \u0000 or 0
• double: 0.0
• boolean: false
• reference: null

Just want to clarify that local variables (ie. declared in block, eg. method, for loop, while loop, try-catch, etc.) are not initialized to default values and must be explicitly initialized.

you can try Expiring Map http://www.java2s.com/Code/Java/Collections-Data-Structure/ExpiringMap.htm a class from The Apache MINA Project

This helped me ..

@Override
public void onBackPressed() {
    startActivity(new Intent(currentActivity.this, LastActivity.class));
    finish();
}

OR????? even you can use this for drawer toggle also

@Override
public void onBackPressed() {
    DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
    if (drawer.isDrawerOpen(GravityCompat.START)) {
        drawer.closeDrawer(GravityCompat.START);
    } else {
        super.onBackPressed();
    }
        startActivity(new Intent(currentActivity.this, LastActivity.class));
    finish();

}

I hope this would help you.. :)

You failed to specify the exact columns (data) to test for normality. Use this instead

shapiro.test(heisenberg$HWWIchg)

Store information:

static final String PLAYER_SCORE = "playerScore";
static final String PLAYER_LEVEL = "playerLevel";

@Override
public void onSaveInstanceState(Bundle savedInstanceState) {
    // Save the user's current game state
    savedInstanceState.putInt(PLAYER_SCORE, mCurrentScore);
    savedInstanceState.putInt(PLAYER_LEVEL, mCurrentLevel);

// Always call the superclass so it can save the view hierarchy state
super.onSaveInstanceState(savedInstanceState);
}

If you don't want to restore information in your onCreate-Method:

Here are the examples: Recreating an Activity

Instead of restoring the state during onCreate() you may choose to implement onRestoreInstanceState(), which the system calls after the onStart() method. The system calls onRestoreInstanceState() only if there is a saved state to restore, so you do not need to check whether the Bundle is null

public void onRestoreInstanceState(Bundle savedInstanceState) {
// Always call the superclass so it can restore the view hierarchy
super.onRestoreInstanceState(savedInstanceState);

// Restore state members from saved instance
mCurrentScore = savedInstanceState.getInt(PLAYER_SCORE);
mCurrentLevel = savedInstanceState.getInt(PLAYER_LEVEL);
}

Use System.Linq.Enumerable.OrderByDescending()?

For example:

var items = someEnumerable.OrderByDescending();

You can use this: if ( str[4] === 'r' ) str = str.slice(0, 4) + str.slice(5)

Explanation:

1. if ( str[4] === 'r' )
   Check if the 5th character is a 'r'
   

2. str.slice(0, 4)
   Slice the string to get everything before the 'r'

3. + str.slice(5)
   Add the rest of the string.

Minified: s=s[4]=='r'?s.slice(0,4)+s.slice(5):s [37 bytes!]

DEMO:

function remove5thR (s) {_x000D_
  s=s[4]=='r'?s.slice(0,4)+s.slice(5):s;_x000D_
  console.log(s); // log output_x000D_
}_x000D_
_x000D_
remove5thR('crt/r2002_2')  // > 'crt/2002_2'_x000D_
remove5thR('crt|r2002_2')  // > 'crt|2002_2'_x000D_
remove5thR('rrrrr')        // > 'rrrr'_x000D_
remove5thR('RRRRR')        // > 'RRRRR' (no change)

The following OpenJDK changeset from 22 January 2016 appears to be related: http://hg.openjdk.java.net/jdk8u/jdk8u/jdk/rev/32f64c19b5fb (commit message "8144430: Improve JMX connections"). The changeset seems to be related to this vulnerability, https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2016-3427, which is mentioned in a comment to this Red Hat bug report, https://bugzilla.redhat.com/show_bug.cgi?id=1336481.

The Update 91 release notes document mentions JDK-8144430 (non-public ticket): http://www.oracle.com/technetwork/java/javase/8u91-relnotes-2949462.html.

In "Oracle Critical Patch Update Advisory - April 2016", the CVE-2016-3427 vulnerability is mentioned: http://www.oracle.com/technetwork/security-advisory/cpuapr2016v3-2985753.html.

The best bitmap encoder is the one you do not write yourself. The file format is a lot more involved, than one might expect. This is evidenced by the fact, that all proposed answers do not create a monochrome (1bpp) bitmap, but rather write out 24bpp files, that happen to only use 2 colors.

The following is a Windows-only solution, using the Windows Imaging Component. It doesn't rely on any external/3rd party libraries, other than what ships with Windows.

Like every C++ program, we need to include several header files. And link to Windowscodecs.lib while we're at it:

#include <Windows.h>
#include <comdef.h>
#include <comip.h>
#include <comutil.h>
#include <wincodec.h>

#include <vector>

#pragma comment(lib, "Windowscodecs.lib")

Next up, we declare our container (a vector, of vectors! Of bool!), and a few smart pointers for convenience:

using _com_util::CheckError;
using container = std::vector<std::vector<bool>>;

_COM_SMARTPTR_TYPEDEF(IWICImagingFactory, __uuidof(IWICImagingFactory));
_COM_SMARTPTR_TYPEDEF(IWICBitmapEncoder, __uuidof(IWICBitmapEncoder));
_COM_SMARTPTR_TYPEDEF(IWICBitmapFrameEncode, __uuidof(IWICBitmapFrameEncode));
_COM_SMARTPTR_TYPEDEF(IWICStream, __uuidof(IWICStream));
_COM_SMARTPTR_TYPEDEF(IWICPalette, __uuidof(IWICPalette));

With that all settled, we can jump right into the implementation. There's a bit of setup required to get a factory, an encoder, a frame, and get everything prepared:

void write_bitmap(wchar_t const* pathname, container const& data)
{
    // Create factory
    IWICImagingFactoryPtr sp_factory { nullptr };
    CheckError(sp_factory.CreateInstance(CLSID_WICImagingFactory, nullptr,
                                         CLSCTX_INPROC_SERVER));

    // Create encoder
    IWICBitmapEncoderPtr sp_encoder { nullptr };
    CheckError(sp_factory->CreateEncoder(GUID_ContainerFormatBmp, nullptr, &sp_encoder));

    // Create stream
    IWICStreamPtr sp_stream { nullptr };
    CheckError(sp_factory->CreateStream(&sp_stream));
    CheckError(sp_stream->InitializeFromFilename(pathname, GENERIC_WRITE));

    // Initialize encoder with stream
    CheckError(sp_encoder->Initialize(sp_stream, WICBitmapEncoderNoCache));

    // Create new frame
    IWICBitmapFrameEncodePtr sp_frame { nullptr };
    IPropertyBag2Ptr sp_properties { nullptr };
    CheckError(sp_encoder->CreateNewFrame(&sp_frame, &sp_properties));

    // Initialize frame with default properties
    CheckError(sp_frame->Initialize(sp_properties));

    // Set pixel format
    // SetPixelFormat() requires a pointer to non-const
    auto pf { GUID_WICPixelFormat1bppIndexed };
    CheckError(sp_frame->SetPixelFormat(&pf));
    if (!::IsEqualGUID(pf, GUID_WICPixelFormat1bppIndexed))
    {
        // Report unsupported pixel format
        CheckError(WINCODEC_ERR_UNSUPPORTEDPIXELFORMAT);
    }

    // Set size derived from data argument
    auto const width { static_cast<UINT>(data.size()) };
    auto const height { static_cast<UINT>(data[0].size()) };
    CheckError(sp_frame->SetSize(width, height));

    // Set palette on frame. This is required since we use an indexed pixel format.
    // Only GIF files support global palettes, so make sure to set it on the frame
    // rather than the encoder.
    IWICPalettePtr sp_palette { nullptr };
    CheckError(sp_factory->CreatePalette(&sp_palette));
    CheckError(sp_palette->InitializePredefined(WICBitmapPaletteTypeFixedBW, FALSE));
    CheckError(sp_frame->SetPalette(sp_palette));

At that point everything is set up, and we have a frame to dump our data into. For 1bpp files, every byte stores the information of 8 pixels. The left-most pixel is stored in the MSB, with pixels following all the way down to the right-most pixel stored in the LSB.

The code isn't entirely important; you'll be replacing that with whatever suits your needs, when you replace the data layout of your input anyway:

    // Write data to frame
    auto const stride { (width * 1 + 7) / 8 };
    auto const size { height * stride };
    std::vector<unsigned char> buffer(size, 127u);
    // Convert data to match required layout. Each byte stores 8 pixels, with the
    // MSB being the leftmost, the LSB the right-most.
    for (size_t x { 0 }; x < data.size(); ++x)
    {
        for (size_t y { 0 }; y < data[x].size(); ++y)
        {
            auto shift { x % 8 };
            auto mask { 0x80 >> shift };
            auto bit { mask * data[x][y] };
            auto& value { buffer[y * stride + x / 8] };
            value &= ~mask;
            value |= bit;
        }
    }
    CheckError(sp_frame->WritePixels(height, stride,
                                     static_cast<UINT>(buffer.size()), buffer.data()));

What's left is to commit the changes to the frame and the encoder, which will ultimately write the image file to disk:

    // Commit frame
    CheckError(sp_frame->Commit());

    // Commit image
    CheckError(sp_encoder->Commit());
}

This is a test program, writing out an image to a file passed as the first command-line argument:

#include <iostream>

int wmain(int argc, wchar_t* argv[])
try
{
    if (argc != 2)
    {
        return -1;
    }

    CheckError(::CoInitializeEx(nullptr, COINIT_APARTMENTTHREADED));


    // Create 64x64 matrix
    container data(64, std::vector<bool>(64, false));
    // Fill with arrow pointing towards the upper left
    for (size_t i { 0 }; i < data.size(); ++i)
    {
        data[0][i] = true;
        data[i][0] = true;
        data[i][i] = true;
    }
    ::write_bitmap(argv[1], data);

It produces the following image (true 1bpp, 574 bytes in size):

You can also work with "overflow: hidden" or "overflow-x: hidden" (for just the width). This requires a defined width (and/or height?) and maybe a "display: block" as well.

"Overflow:Hidden" hides the whole content, which does not fit into the defined box.

Example:

http://jsfiddle.net/NAJvp/

HTML:

<table border="1">
    <tr>
        <td><div>aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa</div></td>
        <td>bbb</td>
        <td>cccc</td>
    </tr>
</table>

CSS:

td div { width: 100px; overflow-y: hidden; }

EDIT: Shame on me, I've seen, you already use "overflow". I guess it doesn't work, because you don't set "display: block" to your element ...

The simplest thing you can do is use reset.css. It normalizes the default stylesheet across browsers, and coincidentally allows button { vertical-align: middle; } to work just fine. Give it a shot - I use it in virtually all of my projects just to kill little bugs like this.

Use this function to run your program in background. It cross-platform and fully customizable.

<?php
function startBackgroundProcess(
    $command,
    $stdin = null,
    $redirectStdout = null,
    $redirectStderr = null,
    $cwd = null,
    $env = null,
    $other_options = null
) {
    $descriptorspec = array(
        1 => is_string($redirectStdout) ? array('file', $redirectStdout, 'w') : array('pipe', 'w'),
        2 => is_string($redirectStderr) ? array('file', $redirectStderr, 'w') : array('pipe', 'w'),
    );
    if (is_string($stdin)) {
        $descriptorspec[0] = array('pipe', 'r');
    }
    $proc = proc_open($command, $descriptorspec, $pipes, $cwd, $env, $other_options);
    if (!is_resource($proc)) {
        throw new \Exception("Failed to start background process by command: $command");
    }
    if (is_string($stdin)) {
        fwrite($pipes[0], $stdin);
        fclose($pipes[0]);
    }
    if (!is_string($redirectStdout)) {
        fclose($pipes[1]);
    }
    if (!is_string($redirectStderr)) {
        fclose($pipes[2]);
    }
    return $proc;
}

Note that after command started, by default this function closes the stdin and stdout of running process. You can redirect process output into some file via $redirectStdout and $redirectStderr arguments.

Note for windows users:
You cannot redirect stdout/stderr to nul in the following manner:

startBackgroundProcess('ping yandex.com', null, 'nul', 'nul');

However, you can do this:

startBackgroundProcess('ping yandex.com >nul 2>&1');

Notes for *nix users:

1) Use exec shell command if you want get actual PID:

$proc = startBackgroundProcess('exec ping yandex.com -c 15', null, '/dev/null', '/dev/null');
print_r(proc_get_status($proc));

2) Use $stdin argument if you want to pass some data to the input of your program:

startBackgroundProcess('cat > input.txt', "Hello world!\n");

Heroku has deprecated the --db option now, so now use:

heroku pg:reset DATABASE_URL --confirm {the name of your app}

It's a little confusing because you use the literal text SHARED_DATABASE but where I have written {the name of your app} substitute the name of your app. For example, if your app is called my_great_app then you use:

heroku pg:reset DATABASE_URL --confirm my_great_app

After running the repair I was able to start the mongod proccessor but as root, which meant that service mongod start would not work. To repair this issue, I needed to make sure that all the files inside the database folder were owned and grouped to mongod. I did this by the following:

1. Check the file permissions inside your database folder
   1. note you need to be in your dbpath folder mine was /var/lib/mongo I went to cd /var/lib
   2. I ran ls -l mongo
2. This showed me that databases were owned by root, which is wrong. I ran the following to fix this: chown -R mongod:mongod mongo. This changed the owner and group of every file in the folder to mongod. (If using the mongodb package, chown -R mongodb:mongodb mongodb)

I hope this helps someone else in the future.

A timestamp is a point in time. Typically this can be represented by a number of milliseconds past an epoc (the Unix Epoc of Jan 1 1970 12AM UTC). The format of that point in time depends on the time zone. While it is the same point in time, the "hours value" is not the same among time zones and one must take into account the offset from the UTC.

Here's some code to illustrate. A point is time is captured in three different ways.

var moment = require( 'moment' );

var localDate = new Date();
var localMoment = moment();
var utcMoment = moment.utc();
var utcDate = new Date( utcMoment.format() );

//These are all the same
console.log( 'localData unix = ' + localDate.valueOf() );
console.log( 'localMoment unix = ' + localMoment.valueOf() );
console.log( 'utcMoment unix = ' + utcMoment.valueOf() );

//These formats are different
console.log( 'localDate = ' + localDate );
console.log( 'localMoment string = ' + localMoment.format() );
console.log( 'utcMoment string = ' + utcMoment.format() );
console.log( 'utcDate  = ' + utcDate );

//One to show conversion
console.log( 'localDate as UTC format = ' + moment.utc( localDate ).format() );
console.log( 'localDate as UTC unix = ' + moment.utc( localDate ).valueOf() );

Which outputs this:

localData unix = 1415806206570
localMoment unix = 1415806206570
utcMoment unix = 1415806206570
localDate = Wed Nov 12 2014 10:30:06 GMT-0500 (EST)
localMoment string = 2014-11-12T10:30:06-05:00
utcMoment string = 2014-11-12T15:30:06+00:00
utcDate  = Wed Nov 12 2014 10:30:06 GMT-0500 (EST)
localDate as UTC format = 2014-11-12T15:30:06+00:00
localDate as UTC unix = 1415806206570

In terms of milliseconds, each are the same. It is the exact same point in time (though in some runs, the later millisecond is one higher).

As far as format, each can be represented in a particular timezone. And the formatting of that timezone'd string looks different, for the exact same point in time!

Are you going to compare these time values? Just convert to milliseconds. One value of milliseconds is always less than, equal to or greater than another millisecond value.

Do you want to compare specific 'hour' or 'day' values and worried they "came from" different timezones? Convert to UTC first using moment.utc( existingDate ), and then do operations. Examples of those conversions, when coming out of the DB, are the last console.log calls in the example.

Thnaks for answer. I tried it myself too to an Empty Project and - lo behold allmighty creator of heaven and seven seas - it worked. I originally had ListBox inside which was inside of root . For some reason ListBox doesn't like being inside of StackPanel, at all! =)

USe session.evict(object); The function of evict() method is used to remove instance from the session cache. So for first time saving the object ,save object by calling session.save(object) method before evicting the object from the cache. In the same way update object by calling session.saveOrUpdate(object) or session.update(object) before calling evict().

I think the accepted answer is not the perfect solution because it converts to string.

If you don't wanna convert to string and back to a double use double.toPrecision(decimalNumber) from GetX package.

If you don't wanna use GetX just for this (I highly recommend GetX, it will change your life with flutter) you can copy and paste this.

import 'dart:math';

extension Precision on double {
  double toPrecision(int fractionDigits) {
    var mod = pow(10, fractionDigits.toDouble()).toDouble();
    return ((this * mod).round().toDouble() / mod);
  }
}

You are trying to do a logarithm of something that is not positive.

Logarithms figure out the base after being given a number and the power it was raised to. log(0) means that something raised to the power of 2 is 0. An exponent can never result in 0*, which means that log(0) has no answer, thus throwing the math domain error

*Note: 0^0 can result in 0, but can also result in 1 at the same time. This problem is heavily argued over.

Are you meaning?

data2 <- data1[good,]

With

data1[good]

you're selecting columns in a wrong way (using a logical vector of complete rows).

Consider that parameter pollutant is not used; is it a column name that you want to extract? if so it should be something like

data2 <- data1[good, pollutant]

Furthermore consider that you have to rbind the data.frames inside the for loop, otherwise you get only the last data.frame (its completed.cases)

And last but not least, i'd prefer generating filenames eg with

id <- 1:322
paste0( directory, "/", gsub(" ", "0", sprintf("%3d",id)), ".csv")

A little modified chunk of ?sprintf

The string fmt (in our case "%3d") contains normal characters, which are passed through to the output string, and also conversion specifications which operate on the arguments provided through .... The allowed conversion specifications start with a % and end with one of the letters in the set aAdifeEgGosxX%. These letters denote the following types:

• d: integer

Eg a more general example

    sprintf("I am %10d years old", 25)
[1] "I am         25 years old"
          ^^^^^^^^^^
          |        |
          1       10

You have to use implicitly unwrapped optionals so that Swift can cope with circular dependencies (parent <-> child of the UI components in this case) during the initialization phase.

@IBOutlet var imgBook: UIImageView!
@IBOutlet var titleBook: UILabel!
@IBOutlet var pageBook: UILabel!

Read this doc, they explain it all nicely.

The following key combinations are used to do things:

CTRL + M + M → Collapse / Expand current preset area (e.g. Method)

CTRL + M + H → Collapse / Hide (Expand) current selection

CTRL + M + O → Collapse all(Collapse declaration bodies)

CTRL + M + A → Collapse all

CTRL + M + X → Expand all

CTRL + M + L → Toggle all

There some options in the context menu under Outlining.

PNG file you attached looks really blurred. In case if you need to use additional post-processing for each image you generated as PDF preview, you will decrease performance of your solution.

2JPEG can convert PDF file you attached to a nice sharpen JPG and crop empty margins in one call:

You basically need to run the installation again to rebuild the master database with the new collation. You cannot change the entire server's collation any other way.

See:

• MSDN: Setting and changing the server collation
• How to change database or server collation (in the middle of the page)

Update: if you want to change the collation of a database, you can get the current collation using this snippet of T-SQL:

SELECT name, collation_name 
FROM sys.databases
WHERE name = 'test2'   -- put your database name here

This will yield a value something like:

Latin1_General_CI_AS

The _CI means "case insensitive" - if you want case-sensitive, use _CS in its place:

Latin1_General_CS_AS

So your T-SQL command would be:

ALTER DATABASE test2 -- put your database name here
   COLLATE Latin1_General_CS_AS   -- replace with whatever collation you need

You can get a list of all available collations on the server using:

SELECT * FROM ::fn_helpcollations()

You can see the server's current collation using:

SELECT SERVERPROPERTY ('Collation')

I believe python just has next() and according to the doc, it throws an exception is there are no more elements.

http://docs.python.org/library/stdtypes.html#iterator-types

It means that the value type in question is a nullable type

Nullable types are instances of the System.Nullable struct. A nullable type can represent the correct range of values for its underlying value type, plus an additional null value. For example, a Nullable<Int32>, pronounced "Nullable of Int32," can be assigned any value from -2147483648 to 2147483647, or it can be assigned the null value. A Nullable<bool> can be assigned the values true, false, or null. The ability to assign null to numeric and Boolean types is especially useful when you are dealing with databases and other data types that contain elements that may not be assigned a value. For example, a Boolean field in a database can store the values true or false, or it may be undefined.

class NullableExample
{
  static void Main()
  {
      int? num = null;

      // Is the HasValue property true?
      if (num.HasValue)
      {
          System.Console.WriteLine("num = " + num.Value);
      }
      else
      {
          System.Console.WriteLine("num = Null");
      }

      // y is set to zero
      int y = num.GetValueOrDefault();

      // num.Value throws an InvalidOperationException if num.HasValue is false
      try
      {
          y = num.Value;
      }
      catch (System.InvalidOperationException e)
      {
          System.Console.WriteLine(e.Message);
      }
  }
}

By default you can't use PHP in HTML pages.

To do that, modify your .htacccess file with the following:

AddType application/x-httpd-php .html

I know the reason why it is the way it is has already been addressed, but when it comes to "custom" boolean formatting, I've got two extension methods that I can't live without anymore :-)

public static class BoolExtensions
{
    public static string ToString(this bool? v, string trueString, string falseString, string nullString="Undefined") {
        return v == null ? nullString : v.Value ? trueString : falseString;
    }
    public static string ToString(this bool v, string trueString, string falseString) {
        return ToString(v, trueString, falseString, null);
    }
}

Usage is trivial. The following converts various bool values to their Portuguese representations:

string verdadeiro = true.ToString("verdadeiro", "falso");
string falso = false.ToString("verdadeiro", "falso");
bool? v = null;
string nulo = v.ToString("verdadeiro", "falso", "nulo");

For .NET 4.0 and higher, you can compare elements in array or tuples using the StructuralComparisons type:

object[] a1 = { "string", 123, true };
object[] a2 = { "string", 123, true };
        
Console.WriteLine (a1 == a2);        // False (because arrays is reference types)
Console.WriteLine (a1.Equals (a2));  // False (because arrays is reference types)
        
IStructuralEquatable se1 = a1;
//Next returns True
Console.WriteLine (se1.Equals (a2, StructuralComparisons.StructuralEqualityComparer)); 

I've written an article that explains how to extend the Distinct function so that you can do as follows:

var people = new List<Person>();

people.Add(new Person(1, "a", "b"));
people.Add(new Person(2, "c", "d"));
people.Add(new Person(1, "a", "b"));

foreach (var person in people.Distinct(p => p.ID))
    // Do stuff with unique list here.

Here's the article (now in the Web Archive): Extending LINQ - Specifying a Property in the Distinct Function

There is a condition, when all of the values that you are checking are the same, where @jerryjvl's code would return NaN.

if (OldMin != OldMax && NewMin != NewMax):
    return (((OldValue - OldMin) * (NewMax - NewMin)) / (OldMax - OldMin)) + NewMin
else:
    return (NewMax + NewMin) / 2

Added shortcut Ctrl+Shift+X C to Keybindings (Window -> Preferences -> filter for Keys) when 'Editing Java Source' for 'Remove Active Session'.

You're really close. Try using a large row number with End(xlUp)

Function ultimaFilaBlanco(col As String) As Long

        Dim lastRow As Long
        With ActiveSheet
            lastRow = ActiveSheet.Cells(1048576, col).End(xlUp).row
        End With

        ultimaFilaBlanco = lastRow

End Function

This one command workes for me (Suse):

mail-srv:/var/log # tail -f /var/log/mail.info |grep --line-buffered LOGIN  >> logins_to_mail

collecting logins to mail service

We can change this yyyy-mm-dd format to dd-mm-yyyy in javascript by using split method.

let dateyear= "2020-03-18";
let arr = dateyear.split('-') //now we get array of these and we can made in any format as we want
let dateFormat = arr[2] + "-" + arr[1] + "-" + arr[0]  //In dd-mm-yyyy format

You can use the UNPIVOT function to convert the columns into rows:

select id, entityId,
  indicatorname,
  indicatorvalue
from yourtable
unpivot
(
  indicatorvalue
  for indicatorname in (Indicator1, Indicator2, Indicator3)
) unpiv;

Note, the datatypes of the columns you are unpivoting must be the same so you might have to convert the datatypes prior to applying the unpivot.

You could also use CROSS APPLY with UNION ALL to convert the columns:

select id, entityid,
  indicatorname,
  indicatorvalue
from yourtable
cross apply
(
  select 'Indicator1', Indicator1 union all
  select 'Indicator2', Indicator2 union all
  select 'Indicator3', Indicator3 union all
  select 'Indicator4', Indicator4 
) c (indicatorname, indicatorvalue);

Depending on your version of SQL Server you could even use CROSS APPLY with the VALUES clause:

select id, entityid,
  indicatorname,
  indicatorvalue
from yourtable
cross apply
(
  values
  ('Indicator1', Indicator1),
  ('Indicator2', Indicator2),
  ('Indicator3', Indicator3),
  ('Indicator4', Indicator4)
) c (indicatorname, indicatorvalue);

Finally, if you have 150 columns to unpivot and you don't want to hard-code the entire query, then you could generate the sql statement using dynamic SQL:

DECLARE @colsUnpivot AS NVARCHAR(MAX),
   @query  AS NVARCHAR(MAX)

select @colsUnpivot 
  = stuff((select ','+quotename(C.column_name)
           from information_schema.columns as C
           where C.table_name = 'yourtable' and
                 C.column_name like 'Indicator%'
           for xml path('')), 1, 1, '')

set @query 
  = 'select id, entityId,
        indicatorname,
        indicatorvalue
     from yourtable
     unpivot
     (
        indicatorvalue
        for indicatorname in ('+ @colsunpivot +')
     ) u'

exec sp_executesql @query;

You can use php for making multi-page website.

• Create a header.php in which you should put all your html code for menu's and social media etc
• Insert header.php in your index.php using following code

<? php include 'header.php'; ?>

(Above code will dump all html code before this)Your site body content.

• Similarly you can create footer and other elements with ease. PHP built-in support html code in their extensions. So, better learn this easy fix.

You can scale the image with pygame.transform.scale:

import pygame
picture = pygame.image.load(filename)
picture = pygame.transform.scale(picture, (1280, 720))

You can then get the bounding rectangle of picture with

rect = picture.get_rect()

and move the picture with

rect = rect.move((x, y))
screen.blit(picture, rect)

where screen was set with something like

screen = pygame.display.set_mode((1600, 900))

To allow your widgets to adjust to various screen sizes, you could make the display resizable:

import os
import pygame
from pygame.locals import *

pygame.init()
screen = pygame.display.set_mode((500, 500), HWSURFACE | DOUBLEBUF | RESIZABLE)
pic = pygame.image.load("image.png")
screen.blit(pygame.transform.scale(pic, (500, 500)), (0, 0))
pygame.display.flip()
while True:
    pygame.event.pump()
    event = pygame.event.wait()
    if event.type == QUIT:
        pygame.display.quit()
    elif event.type == VIDEORESIZE:
        screen = pygame.display.set_mode(
            event.dict['size'], HWSURFACE | DOUBLEBUF | RESIZABLE)
        screen.blit(pygame.transform.scale(pic, event.dict['size']), (0, 0))
        pygame.display.flip()

Yes, that will work as you expect it to. Unfortunately, I seem to be having trouble to find an explicit statement of this in the MySQL manual.

Foreign keys mean the value must exist in the other table. NULL refers to the absence of value, so when you set a column to NULL, it wouldn't make sense to try to enforce constraints on that.

That error means that a function call is only matched by an existing function if all its arguments are of the same type and passed in same order. So if the next f() function

create function f() returns integer as $$ 
    select 1;
$$ language sql;

is called as

select f(1);

It will error out with

ERROR:  function f(integer) does not exist
LINE 1: select f(1);
               ^
HINT:  No function matches the given name and argument types. You might need to add explicit type casts.

because there is no f() function that takes an integer as argument.

So you need to carefully compare what you are passing to the function to what it is expecting. That long list of table columns looks like bad design.

although the answer is for Java, but the code can be easily adapted from this Kotlin String extension I came up with (adapted from that @brcolow provided):

private val escapeChars = charArrayOf(
    '<',
    '(',
    '[',
    '{',
    '\\',
    '^',
    '-',
    '=',
    '$',
    '!',
    '|',
    ']',
    '}',
    ')',
    '?',
    '*',
    '+',
    '.',
    '>'
)

fun String.escapePattern(): String {
    return this.fold("") {
      acc, chr ->
        acc + if (escapeChars.contains(chr)) "\\$chr" else "$chr"
    }
}

fun main() {
    println("(.*)".escapePattern())
}

prints \(\.\*\)

If your library name is say libxyz.so and it is located on path say:

/home/user/myDir

then to link it to your program:

g++ -L/home/user/myDir -lxyz myprog.cpp -o myprog

I use the old PHP way..It unsets all session variables and doesn't require to specify each one of them in an array. And after unsetting the variables we destroy the session.

session_unset();
session_destroy();

I don't know what the .tex extension on your file means. If we are saying that it is any file with any extension you have several methods of reading it.

I have to assume you are using windows because you have mentioned notepad++.

1. Use notepad++. Right click on the file and choose "edit with notepad++"

2. Use notepad Change the filename extension to .txt and double click the file.

3. Use command prompt. Open the folder that your file is in. Hold down shift and right click. (not on the file, but in the folder that the file is in.) Choose "open command window here" from the command prompt type: "type filename.tex"

If these don't work, I would need more detail as to how they are not working. Errors that you may be getting or what you may expect to be in the file might help.

You will want to use the Type.GetType method.

Here is a very simple example:

using System;
using System.Reflection;

class Program
{
    static void Main()
    {
        Type t = Type.GetType("Foo");
        MethodInfo method 
             = t.GetMethod("Bar", BindingFlags.Static | BindingFlags.Public);

        method.Invoke(null, null);
    }
}

class Foo
{
    public static void Bar()
    {
        Console.WriteLine("Bar");
    }
}

I say simple because it is very easy to find a type this way that is internal to the same assembly. Please see Jon's answer for a more thorough explanation as to what you will need to know about that. Once you have retrieved the type my example shows you how to invoke the method.

Simplifying from pctroll's answer, similarly based on this blog post.

# look up the commit id in git log or on github, e.g. 42480f3, then do

You can use either File.Copy(oldFilePath, newFilePath) method or other way is, read file using StreamReader into an string and then use StreamWriter to write the file to destination location.

Your code might look like this :

StreamReader reader = new StreamReader("C:\foo.txt");
string fileContent = reader.ReadToEnd();

StreamWriter writer = new StreamWriter("D:\bar.txt");
writer.Write(fileContent);

You can add exception handling code...

Now the class is this

 <img src="img/img5.jpg" width="200px" class="rounded-circle float-right">

In Java 8,

For small files:

String line = Files.readAllLines(Paths.get("file.txt")).get(n);

For large files:

String line;
try (Stream<String> lines = Files.lines(Paths.get("file.txt"))) {
    line = lines.skip(n).findFirst().get();
}

In Java 7

String line;
try (BufferedReader br = new BufferedReader(new FileReader("file.txt"))) {
    for (int i = 0; i < n; i++)
        br.readLine();
    line = br.readLine();
}

Using Guava on Java 8

private Set<Integer> findDuplicates(List<Integer> input) {
    // Linked* preserves insertion order so the returned Sets iteration order is somewhat like the original list
    LinkedHashMultiset<Integer> duplicates = LinkedHashMultiset.create(input);

    // Remove all entries with a count of 1
    duplicates.entrySet().removeIf(entry -> entry.getCount() == 1);

    return duplicates.elementSet();
}

The way I would do it is to leave the __ init__.py files empty, and do:

import lib.mod1.mod11
lib.mod1.mod11.mod12()

or

from lib.mod1.mod11 import mod12
mod12()

You may find that the mod1 dir is unnecessary, just have mod12.py in lib.

If you use :active selector in combination with :hover you can achieve this according to w3schools as long as the :active selector is called after the :hover selector.

 .info-slide:hover, .info-slide:active{

You'd have to test the FIDDLE in a mobile environment. I can't at the moment.
correction - I just tested in a mobile, it works fine

Just to be a bit left handed...

x ? y : x = value

will assign value to y if x is not 0 (false).

In the fragment where you would like to handle your back button you should attach stuff to your view in the oncreateview

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    View v = inflater.inflate(R.layout.second_fragment, container, false);
    v.setOnKeyListener(pressed);
    return v;
}



@Override
public boolean onKey(View v, int keyCode, KeyEvent event) {
    // TODO Auto-generated method stub
    if( keyCode == KeyEvent.KEYCODE_BACK ){
            // back to previous fragment by tag
            myfragmentclass fragment = (myfragmentclass) getActivity().getSupportFragmentManager().findFragmentByTag(TAG);
            if(fragment != null){
                (getActivity().getSupportFragmentManager().beginTransaction()).replace(R.id.cf_g1_mainframe_fm, fragment).commit();
            }
            return true;
        }
        return false;
    }
};
