Grep has an option called Context Line Control, you can use the --context in that, simply,

| grep -C 5

or

| grep -5

Should do the trick

For Windows: 3 steps

Step1: Just need to give the ext folder path in php.ini

Here

; Directory in which the loadable extensions (modules) reside.
; http://php.net/extension-dir
; extension_dir = "./"
; On windows:
 extension_dir = "C:\php7\ext"

Step 2: Remove the comment from

extension=php_mysqli.dll

Step 3: restart the Apache server.

Joins can only be used when there is an association between entities. Your Employee entity should not have a field named id_team, of type int, mapped to a column. It should have a ManyToOne association with the Team entity, mapped as a JoinColumn:

@ManyToOne
@JoinColumn(name="ID_TEAM")
private Team team;

Then, the following query will work flawlessly:

select e from Employee e inner join e.team

Which will load all the employees, except those that aren't associated to any team.

The same goes for all the other fields which are a foreign key to some other table mapped as an entity, of course (id_boss, id_profession).

It's time for you to read the Hibernate documentation, because you missed an extremely important part of what it is and how it works.

How do I run an executable JAR file? If you have a jar file called Example.jar, follow these rules:

Open a notepad.exe.
Write : java -jar Example.jar.
Save it with the extension .bat.
Copy it to the directory which has the .jar file.
Double click it to run your .jar file.

You can also do it with two sed calls:

$ cat file.txt 
something1:    +12.0   (some unnecessary trailing data (this must go))
something2:    +15.5   (some more unnecessary trailing data)
something4:    +9.0   (some other unnecessary data)
something1:    +13.5  (blah blah blah)
$ sed 's/^[^:]*: *\([+0-9.]\+\) .*/\1/' file.txt | sed -e :a -e '$!N; s/\n/,/; ta'
+12.0,+15.5,+9.0,+13.5

First sed call removes uninteresting data, and the second join all lines.

I use a simple Python HTTP server. When in the directory of the Angular app in question (using a MBP with Mavericks 10.9 and Python 2.x) I simply run

python -m SimpleHTTPServer 8080

And that sets up the simple server on port 8080 letting you visit localhost:8080 on your browser to view the app in development.

Hope that helped!

You can use .concat method to create copy of your array with new data:

this.setState({ myArray: this.state.myArray.concat('new value') })

But beware of special behaviour of .concat method when passing arrays - [1, 2].concat(['foo', 3], 'bar') will result in [1, 2, 'foo', 3, 'bar'].

As an node manager alternative you can use Volta from LinkedIn.

This might be a little late to answer but most simple and accurate way to compute square root is newton's method.

You have a number which you want to compute its square root (num) and you have a guess of its square root (estimate). Estimate can be any number bigger than 0, but a number that makes sense shortens the recursive call depth significantly.

new_estimate = (estimate + num / estimate) / 2

This line computes a more accurate estimate with those 2 parameters. You can pass new_estimate value to the function and compute another new_estimate which is more accurate than the previous one or you can make a recursive function definition like this.

def newtons_method(num, estimate):
    # Computing a new_estimate
    new_estimate = (estimate + num / estimate) / 2
    print(new_estimate)
    # Base Case: Comparing our estimate with built-in functions value
    if new_estimate == math.sqrt(num):
        return True
    else:
        return newtons_method(num, new_estimate)

For example we need to find 30's square root. We know that the result is between 5 and 6.

newtons_method(30,5)

number is 30 and estimate is 5. The result from each recursive calls are:

5.5
5.477272727272727
5.4772255752546215
5.477225575051661

The last result is the most accurate computation of the square root of number. It is the same value as the built-in function math.sqrt().

Changing the data frames list into a list of tuples.

df = pd.DataFrame({'col1': [1, 2, 3], 'col2': [4, 5, 6]})
print(df)
OUTPUT
   col1  col2
0     1     4
1     2     5
2     3     6

records = df.to_records(index=False)
result = list(records)
print(result)
OUTPUT
[(1, 4), (2, 5), (3, 6)]

"Validation injection without submit looping":

I just want to check reCaptcha and some other stuff before HTML5 validation, so I did something like that (the validation function returns true or false):

$(document).ready(function(){
   var application_form = $('form#application-form');

   application_form.on('submit',function(e){

        if(application_form_extra_validation()===true){
           return true;
        }

        e.preventDefault();

   });
});

You want to check if an object is NULL/empty. Being NULL and empty are not the same. Like Justin and Brian have already mentioned, in C++ NULL is an assignment you'd typically associate with pointers. You can overload operator= perhaps, but think it through real well if you actually want to do this. Couple of other things:

1. In C++ NULL pointer is very different to pointer pointing to an 'empty' object.
2. Why not have a bool IsEmpty() method that returns true if an object's variables are reset to some default state? Guess that might bypass the NULL usage.
3. Having something like A* p = new A; ... p = NULL; is bad (no delete p) unless you can ensure your code will be garbage collected. If anything, this'd lead to memory leaks and with several such leaks there's good chance you'd have slow code.
4. You may want to do this class Null {}; Null _NULL; and then overload operator= and operator!= of other classes depending on your situation.

Perhaps you should post us some details about the context to help you better with option 4.

This is bad style, but I'll assume you have a good reason for doing something similar.

<html>
<body>
    <input type="text" id="userInput">give me input</input>
    <button id="submitter">Submit</button>
    <div id="output"></div>
    <script>
        var didClickIt = false;
        document.getElementById("submitter").addEventListener("click",function(){
            // same as onclick, keeps the JS and HTML separate
            didClickIt = true;
        });

        setInterval(function(){
            // this is the closest you get to an infinite loop in JavaScript
            if( didClickIt ) {
                didClickIt = false;
                // document.write causes silly problems, do this instead (or better yet, use a library like jQuery to do this stuff for you)
                var o=document.getElementById("output"),v=document.getElementById("userInput").value;
                if(o.textContent!==undefined){
                    o.textContent=v;
                }else{
                    o.innerText=v;

this can help you even more better, Fast, Convenient & Easiest.

Let me explain backwards:

Consider this...

foo()

... as syntactic sugar for:

foo.__call__()

Where foo can be any object that responds to __call__. When I say any object, I mean it: built-in types, your own classes and their instances.

In the case of built-in types, when you write:

int('10')
unicode(10)

You're essentially doing:

int.__call__('10')
unicode.__call__(10)

That's also why you don't have foo = new int in Python: you just make the class object return an instance of it on __call__. The way Python solves this is very elegant in my opinion.

Another alternative to simulating a F5 key press would be to simply host the WebBrowser control in the Window Forms application. You use the WebBrowser.Navigate method to load your web page and then use a standard Timer and on each tick of the timer you just re-Navigate to the url which will reload the page.

If you don't want to install Homebrew only for install Maven you could simply do this:

1. Download the binary Maven and extract the zip

2. Launch the Terminal and type this command:

   sudo ln -s /path_to_maven_folder/bin/mvn /usr/bin/mvn

You can find more details on this post.

Try this

Check if table have there , and drop the table , then create

WHERE name LIKE '#Customer%')
DROP TABLE #Customer CREATE TABLE Customer(First_Name char(50),Last_Name char(50),Address char(50),City char(50),Country char(25),Birth_Date datetime);", con))

You need to use ?param instead of @param when performing queries to MySQL

 str_carSql = "insert into members_car (car_id, member_id, model, color, chassis_id, plate_number, code) values (?id,?m_id,?model,?color,?ch_id,?pt_num,?code)"
        sqlCommand.Connection = SQLConnection
        sqlCommand.CommandText = str_carSql
        sqlCommand.Parameters.AddWithValue("?id", TextBox20.Text)
        sqlCommand.Parameters.AddWithValue("?m_id", TextBox20.Text)
        sqlCommand.Parameters.AddWithValue("?model", TextBox23.Text)
        sqlCommand.Parameters.AddWithValue("?color", TextBox24.Text)
        sqlCommand.Parameters.AddWithValue("?ch_id", TextBox22.Text)
        sqlCommand.Parameters.AddWithValue("?pt_num", TextBox21.Text)
        sqlCommand.Parameters.AddWithValue("?code", ComboBox1.SelectedItem)
        sqlCommand.ExecuteNonQuery()

Change the catch block to see the actual exception:

  Catch ex As Exception
         MsgBox(ex.Message)   
          Return False

    End Try

You are inside vim. To save changes and quit, type:

<esc> :wq <enter>

That means:

• Press Escape. This should make sure you are in command mode
• type in :wq
• Press Return

An alternative that stdcall in the comments mentions is:

• Press Escape
• Press shift+Z shift+Z (capital Z twice).

We can also use REGEXP

select employee_name 
from employees
where employee_name REGEXP '[ab].*'
order by employee_name

The issue because of not loading jquery ui library.

https://code.jquery.com/ui/1.11.4/jquery-ui.js - CDN source file

Call above path in your file.

As a side note processes that uses virtual accounts (NT Service\MyService and IIS AppPool\MyAppPool) are still running under the "NETWORK SERVICE" account as this post suggests http://www.adopenstatic.com/cs/blogs/ken/archive/2008/01/29/15759.aspx. The only difference is that these processes are members of the "NT Service\MyService" or "IIS AppPool\MyAppPool" groups (as these are actually groups and not users). This is also the reason why the processes authenticate at the network as the machine the same way NETWORK SERVICE account does.

The way to secure access is not to depend upon this accounts not having NETWORK SERVICE privileges but to grant more permissions specifically to "NT Service\MyService" or "IIS AppPool\MyAppPool" and to remove permissions for "Users" if necessary.

If anyone has more accurate or contradictional information please post.

Unfortunately you can't use Process.Start() to start an instance of the currently running process. According to the Process.Start() docs: "If the process is already running, no additional process resource is started..."

This technique will work fine under the VS debugger (because VS does some kind of magic that causes Process.Start to think the process is not already running), but will fail when not run under the debugger. (Note that this may be OS-specific - I seem to remember that in some of my testing, it worked on either XP or Vista, but I may just be remembering running it under the debugger.)

This technique is exactly the one used by the last programmer on the project on which I'm currently working, and I've been trying to find a workaround for this for quite some time. So far, I've only found one solution, and it just feels dirty and kludgy to me: start a 2nd application, that waits in the background for the first application to terminate, then re-launches the 1st application. I'm sure it would work, but, yuck.

Edit: Using a 2nd application works. All I did in the second app was:

    static void RestartApp(int pid, string applicationName )
    {
        // Wait for the process to terminate
        Process process = null;
        try
        {
            process = Process.GetProcessById(pid);
            process.WaitForExit(1000);
        }
        catch (ArgumentException ex)
        {
            // ArgumentException to indicate that the 
            // process doesn't exist?   LAME!!
        }
        Process.Start(applicationName, "");
    }

(This is a very simplified example. The real code has lots of sanity checking, error handling, etc)

I had some issues playing on Android Phone. After few tries I found out that when Data Saver is on there is no auto play:

There is no autoplay if Data Saver mode is enabled. If Data Saver mode is enabled, autoplay is disabled in Media settings.

You can use jsoup to parse any kind of web page. Here you can find the jsoup library and full source code.

Here is an example: http://desicoding.blogspot.com/2011/03/how-to-parse-html-in-java-jsoup.html

To install in Eclipse:

1. Right Click on project
2. BuildPath
3. Add External Archives
4. select the .jar file

You can parse according to tag/parent/child very comfortably

GNU parallel

I was making a synthetic compilation benchmark and couldn't be bothered to write a Makefile, so I used:

sudo apt-get install parallel
ls | grep -E '\.c$' | parallel -t --will-cite "gcc -c -o '{.}.o' '{}'"

Explanation:

• {.} takes the input argument and removes its extension
• -t prints out the commands being run to give us an idea of progress
• --will-cite removes the request to cite the software if you publish results using it...

parallel is so convenient that I could even do a timestamp check myself:

ls | grep -E '\.c$' | parallel -t --will-cite "\
  if ! [ -f '{.}.o' ] || [ '{}' -nt '{.}.o' ]; then
    gcc -c -o '{.}.o' '{}'
  fi
"

xargs -P can also run jobs in parallel, but it is a bit less convenient to do the extension manipulation or run multiple commands with it: Calling multiple commands through xargs

Parallel linking was asked at: Can gcc use multiple cores when linking?

TODO: I think I read somewhere that compilation can be reduced to matrix multiplication, so maybe it is also possible to speed up single file compilation for large files. But I can't find a reference now.

Tested in Ubuntu 18.10.

Don't you just want:

",".join(l)

Obviously it gets more complicated if you need to quote/escape commas etc in the values. In that case I would suggest looking at the csv module in the standard library:

https://docs.python.org/library/csv.html

"simple solution is here"

1 .Create a folder named libs under the app directory for that matter any directory within the project..

2 .Copy Paste your Library to libs folder

3.You simply copy the JAR to your libs/ directory and then from inside Android Studio, right click the Jar that shows up under libs/ > Add As Library..

Peace!

To answer "why" someone might use it, I was tempted to use it since I had the $_POST values stored after the page refresh or while going from one page to another. My sense tells me this is not a good practice, but it works nevertheless.

Sharing a few functions which I created for dates:

Please note that I wanted to get time for a particular location (not just UTC time). If you want UTC time, just remove loc variable and .In(loc) function call.

func GetTimeStamp() string {
     loc, _ := time.LoadLocation("America/Los_Angeles")
     t := time.Now().In(loc)
     return t.Format("20060102150405")
}
func GetTodaysDate() string {
    loc, _ := time.LoadLocation("America/Los_Angeles")
    current_time := time.Now().In(loc)
    return current_time.Format("2006-01-02")
}

func GetTodaysDateTime() string {
    loc, _ := time.LoadLocation("America/Los_Angeles")
    current_time := time.Now().In(loc)
    return current_time.Format("2006-01-02 15:04:05")
}

func GetTodaysDateTimeFormatted() string {
    loc, _ := time.LoadLocation("America/Los_Angeles")
    current_time := time.Now().In(loc)
    return current_time.Format("Jan 2, 2006 at 3:04 PM")
}

func GetTimeStampFromDate(dtformat string) string {
    form := "Jan 2, 2006 at 3:04 PM"
    t2, _ := time.Parse(form, dtformat)
    return t2.Format("20060102150405")
}

If you want to format your table via kable, you can use row.names = F

kable(df, row.names = F)

You can use :text Selector to select all inputs with type text

Working Fiddle

$(document).ready(function () {
    $(":text").css({    //or $("input:text")
        'background': 'green',
        'color':'#fff'
    });
});

:text is a jQuery extension and not part of the CSS specification, queries using :text cannot take advantage of the performance boost provided by the native DOM querySelectorAll() method. For better performance in modern browsers, use [type="text"] instead. This will work for IE6+.

$("[type=text]").css({  // or $("input[type=text]")
    'background': 'green',
    'color':'#fff'
});

CSS

[type=text] // or input[type=text] 
{
    background: green;
}

I enclose my example code with <pre class="brush: java"></pre> tags and use SyntaxHighlighter for published javadocs. It doesn't hurt IDE and makes published code examples beautiful.

From R..'s answer:

However, this is probably a very bad idea, because the resulting type is an array type, but users of it won't see that it's an array type. If used as a function argument, it will be passed by reference, not by value, and the sizeof for it will then be wrong.

Users who don't see that it's an array will most likely write something like this (which fails):

#include <stdio.h>

typedef int twoInts[2];

void print(twoInts *twoIntsPtr);
void intermediate (twoInts twoIntsAppearsByValue);

int main () {
    twoInts a;
    a[0] = 0;
    a[1] = 1;
    print(&a);
    intermediate(a);
    return 0;
}
void intermediate(twoInts b) {
    print(&b);
}

void print(twoInts *c){
    printf("%d\n%d\n", (*c)[0], (*c)[1]);
}

It will compile with the following warnings:

In function ‘intermediate’:
warning: passing argument 1 of ‘print’ from incompatible pointer type [enabled by default]
    print(&b);
     ^
note: expected ‘int (*)[2]’ but argument is of type ‘int **’
    void print(twoInts *twoIntsPtr);
         ^

And produces the following output:

0
1
-453308976
32767

For simple cases like this, TimeUnit should be used. TimeUnit usage is a bit more explicit about what is being represented and is also much easier to read and write when compared to doing all of the arithmetic calculations explicitly. For example, to calculate the number days from milliseconds, the following statement would work:

    long days = TimeUnit.MILLISECONDS.toDays(milliseconds);

For cases more advanced, where more finely grained durations need to be represented in the context of working with time, an all encompassing and modern date/time API should be used. For JDK8+, java.time is now included (here are the tutorials and javadocs). For earlier versions of Java joda-time is a solid alternative.

In order to simulate the issue that you are facing, I created the following sample using SSIS 2008 R2 with SQL Server 2008 R2 backend. The example is based on what I gathered from your question. This example doesn't provide a solution but it might help you to identify where the problem could be in your case.

Created a simple CSV file with two columns namely order number and order date. As you had mentioned in your question, values of both the columns are qualified with double quotes (") and also the lines end with Line Feed (\n) with the date being the last column. The below screenshot was taken using Notepad++, which can display the special characters in a file. LF in the screenshot denotes Line Feed.

Created a simple table named dbo.Destination in the SQL Server database to populate the CSV file data using SSIS package. Create script for the table is given below.

CREATE TABLE [dbo].[Destination](
    [OrderNumber] [varchar](50) NULL,
    [OrderDate] [date] NULL
) ON [PRIMARY]
GO

On the SSIS package, I created two connection managers. SQLServer was created using the OLE DB Connection to connect to the SQL Server database. FlatFile is a flat file connection manager.

Flat file connection manager was configured to read the CSV file and the settings are shown below. The red arrows indicate the changes made.

Provided a name to the flat file connection manager. Browsed to the location of the CSV file and selected the file path. Entered the double quote (") as the text qualifier. Changed the Header row delimiter from {CR}{LF} to {LF}. This header row delimiter change also reflects on the Columns section.

No changes were made in the Columns section.

Changed the column name from Column0 to OrderNumber.

Changed the column name from Column1 to OrderDate and also changed the data type to date [DT_DATE]

Preview of the data within the flat file connection manager looks good.

On the Control Flow tab of the SSIS package, placed a Data Flow Task.

Within the Data Flow Task, placed a Flat File Source and an OLE DB Destination.

The Flat File Source was configured to read the CSV file data using the FlatFile connection manager. Below three screenshots show how the flat file source component was configured.

The OLE DB Destination component was configured to accept the data from Flat File Source and insert it into SQL Server database table named dbo.Destination. Below three screenshots show how the OLE DB Destination component was configured.

Using the steps mentioned in the below 5 screenshots, I added a data viewer on the flow between the Flat File Source and OLE DB Destination.

Before running the package, I verified the initial data present in the table. It is currently empty because I created this using the script provided at the beginning of this post.

Executed the package and the package execution temporarily paused to display the data flowing from Flat File Source to OLE DB Destination in the data viewer. I clicked on the run button to proceed with the execution.

The package executed successfully.

Flat file source data was inserted successfully into the table dbo.Destination.

Here is the layout of the table dbo.Destination. As you can see, the field OrderDate is of data type date and the package still continued to insert the data correctly.

This post even though is not a solution. Hopefully helps you to find out where the problem could be in your scenario.

As I understand it, you want the server be able to send messages through from client 1 to client 2. You cannot directly connect two clients because one of the two ends of a WebSocket connection needs to be a server.

This is some pseudocodish JavaScript:

Client:

var websocket = new WebSocket("server address");

websocket.onmessage = function(str) {
  console.log("Someone sent: ", str);
};

// Tell the server this is client 1 (swap for client 2 of course)
websocket.send(JSON.stringify({
  id: "client1"
}));

// Tell the server we want to send something to the other client
websocket.send(JSON.stringify({
  to: "client2",
  data: "foo"
}));

Server:

var clients = {};

server.on("data", function(client, str) {
  var obj = JSON.parse(str);

  if("id" in obj) {
    // New client, add it to the id/client object
    clients[obj.id] = client;
  } else {
    // Send data to the client requested
    clients[obj.to].send(obj.data);
  }
});

By encode, do you mean: Convert all applicable characters to HTML entities?

htmlspecialchars or htmlentities

You can also use strip_tags if you want to remove all HTML tags :

strip_tags

Note: this will NOT stop all XSS attacks

Here is an example of using a dynamic T-SQL query and then extracting the results should you have more than one column of returned values (notice the dynamic table name):

DECLARE 
@strSQLMain nvarchar(1000),
@recAPD_number_key char(10),    
@Census_sub_code varchar(1),
@recAPD_field_name char(100),
@recAPD_table_name char(100),
@NUMBER_KEY varchar(10),

if object_id('[Permits].[dbo].[myTempAPD_Txt]') is not null 

    DROP TABLE [Permits].[dbo].[myTempAPD_Txt]

CREATE TABLE [Permits].[dbo].[myTempAPD_Txt]
(
    [MyCol1] char(10) NULL,
    [MyCol2] char(1) NULL,

)   
-- an example of what @strSQLMain is : @strSQLMain = SELECT @recAPD_number_key = [NUMBER_KEY], @Census_sub_code=TEXT_029 FROM APD_TXT0 WHERE Number_Key = '01-7212' 
SET @strSQLMain = ('INSERT INTO myTempAPD_Txt SELECT [NUMBER_KEY], '+ rtrim(@recAPD_field_name) +' FROM '+ rtrim(@recAPD_table_name) + ' WHERE Number_Key = '''+ rtrim(@Number_Key) +'''')      
EXEC (@strSQLMain)  
SELECT @recAPD_number_key = MyCol1, @Census_sub_code = MyCol2 from [Permits].[dbo].[myTempAPD_Txt]

DROP TABLE [Permits].[dbo].[myTempAPD_Txt]  

Call runnable whenever you want:

runOnUiThread(run);

OnCreate(), you set your runnable thread:

run = new Runnable() {
    public void run() {
        //reload content
        arraylist.clear();
        arraylist.addAll(db.readAll());
        adapter.notifyDataSetChanged();
        listview.invalidateViews();
        listview.refreshDrawableState();
    }
};

Please remove "C:\ProgramData\Oracle\Java\javapath\java.exe" from the Path variable and add your jdk bin path. It will work.

In my case the I have removed the the above path and added my JDK path which is "C:\Program Files\Java\jdk1.8.0_221\bin"

xhr.getResponseHeader('Set-Cookie');

In SQL Server 2008 you can insert multiple rows using a single SQL INSERT statement.

INSERT INTO MyTable ( Column1, Column2 ) VALUES
( Value1, Value2 ), ( Value1, Value2 )

For reference to this have a look at MOC Course 2778A - Writing SQL Queries in SQL Server 2008.

For example:

INSERT INTO MyTable
  ( Column1, Column2, Column3 )
VALUES
  ('John', 123, 'Lloyds Office'), 
  ('Jane', 124, 'Lloyds Office'), 
  ('Billy', 125, 'London Office'),
  ('Miranda', 126, 'Bristol Office');

You can code it yourself using Paramiko, as suggested above. Alternatively, you can look into Fabric, a python application for doing all the things you asked about:

Fabric is a Python library and command-line tool designed to streamline deploying applications or performing system administration tasks via the SSH protocol. It provides tools for running arbitrary shell commands (either as a normal login user, or via sudo), uploading and downloading files, and so forth.

I think this fits your needs. It is also not a large library and requires no server installation, although it does have dependencies on paramiko and pycrypt that require installation on the client.

The app used to be here. It can now be found here.

* The official, canonical repository is git.fabfile.org
* The official Github mirror is GitHub/bitprophet/fabric

There are several good articles on it, though you should be careful because it has changed in the last six months:

Later: Fabric no longer requires paramiko to install:

This is mostly cosmetic, however: ssh is a fork of paramiko, the maintainer for both libraries is the same (Jeff Forcier, also the author of Fabric), and the maintainer has plans to reunite paramiko and ssh under the name paramiko. (This correction via pbanka.)

You will get rejection message from apple just because the product you have registered for inApp purchase might come under category Non-renewing subscriptions and consumable products. These type of products will not automatically renewable. you need to have explicit restore button in your application.

for other type of products it will automatically restore it.

Please read following text which will clear your concept about this :

Once a transaction has been processed and removed from the queue, your application normally never sees it again. However, if your application supports product types that must be restorable, you must include an interface that allows users to restore these purchases. This interface allows a user to add the product to other devices or, if the original device was wiped, to restore the transaction on the original device.

Store Kit provides built-in functionality to restore transactions for non-consumable products, auto-renewable subscriptions and free subscriptions. To restore transactions, your application calls the payment queue’s restoreCompletedTransactions method. The payment queue sends a request to the App Store to restore the transactions. In return, the App Store generates a new restore transaction for each transaction that was previously completed. The restore transaction object’s originalTransaction property holds a copy of the original transaction. Your application processes a restore transaction by retrieving the original transaction and using it to unlock the purchased content. After Store Kit restores all the previous transactions, it notifies the payment queue observers by calling their paymentQueueRestoreCompletedTransactionsFinished: method.

If the user attempts to purchase a restorable product (instead of using the restore interface you implemented), the application receives a regular transaction for that item, not a restore transaction. However, the user is not charged again for that product. Your application should treat these transactions identically to those of the original transaction. Non-renewing subscriptions and consumable products are not automatically restored by Store Kit. Non-renewing subscriptions must be restorable, however. To restore these products, you must record transactions on your own server when they are purchased and provide your own mechanism to restore those transactions to the user’s devices

for example:

<ImageView android:id="@+id/image_view"     
  android:layout_width="wrap_content"  
  android:layout_height="wrap_content"  
  android:adjustViewBounds="true"  
  android:maxWidth="42dp"  
  android:maxHeight="42dp"  
  android:scaleType="fitCenter"  
  android:layout_marginLeft="3dp"  
  android:src="@drawable/icon"  
  /> 

Add property android:scaleType="fitCenter" and android:adjustViewBounds="true".

Here's a different approach:

1) Use the multiplication character: × ×

2) Hide half of it with overflow:hidden

3) Then add a triangle as a pseudo element for the tip.

The advantage here is that no transforms are necessary. (It will work in IE8+)

Remember to add the activity you want to present, to your AndroidManifest.xml too :-) That was the issue for me.

Open your Android SDK Manager and ensure that you download/install a system image for the API level you are developing with.

Try something like this:

Bitmap bmp = intent.getExtras().get("data");
ByteArrayOutputStream stream = new ByteArrayOutputStream();
bmp.compress(Bitmap.CompressFormat.PNG, 100, stream);
byte[] byteArray = stream.toByteArray();
bmp.recycle();

The problem will be that you cannot represent 0.575 exactly as a binary floating point number (eg a double). Though I don't know exactly it seems that the representation closest is probably just a bit lower and so when rounding it uses the true representation and rounds down.

If you want to avoid this problem then use a more appropriate data type. decimal will do what you want:

Math.Round(0.575M, 2, MidpointRounding.AwayFromZero)

Result: 0.58

The reason that 0.75 does the right thing is that it is easy to represent in binary floating point since it is simple 1/2 + 1/4 (ie 2^-1 +2^-2). In general any finite sum of powers of two can be represented in binary floating point. Exceptions are when your powers of 2 span too great a range (eg 2^100+2 is not exactly representable).

Edit to add:

Formatting doubles for output in C# might be of interest in terms of understanding why its so hard to understand that 0.575 is not really 0.575. The DoubleConverter in the accepted answer will show that 0.575 as an Exact String is 0.5749999999999999555910790149937383830547332763671875 You can see from this why rounding give 0.57.

As far as the compiler is concerned, those two methods are identical. There will be one implementation of both.

This isn't a problem if the two methods are effectively identical, in that they should have the same implementation. If they are contractually different (as per the documentation for each interface), you'll be in trouble.

I prefer minecart as it is extremely easy to use. The below snippet show how to extract images from a pdf:

#pip install minecart
import minecart

pdffile = open('Invoices.pdf', 'rb')
doc = minecart.Document(pdffile)

page = doc.get_page(0) # getting a single page

#iterating through all pages
for page in doc.iter_pages():
    im = page.images[0].as_pil()  # requires pillow
    display(im)

Find *.pem file and place it to the anchors sub-directory or just simply link the *.pem file to there.

yum install -y ca-certificates
update-ca-trust force-enable
sudo ln -s /etc/ssl/your-cert.pem /etc/pki/ca-trust/source/anchors/your-cert.pem
update-ca-trust

This answer may have to be modified depending on what you were trying to achieve with position: fixed;. If all you want is two columns side by side then do the following:

I floated both columns to the left.

Note: I added min-height to each column for illustrative purposes and I simplified your CSS.

  <div id="rightcolumn">_x000D_

If you would like the left column to stay in place as you scroll do the following:

Here we float the right column to the right while adding position: relative; to #wrapper and position: fixed; to #leftcolumn.

A Tale of Two Questions

The question of "How do I test pathname validity and, for valid pathnames, the existence or writability of those paths?" is clearly two separate questions. Both are interesting, and neither have received a genuinely satisfactory answer here... or, well, anywhere that I could grep.

vikki's answer probably hews the closest, but has the remarkable disadvantages of:

• Needlessly opening (...and then failing to reliably close) file handles.
• Needlessly writing (...and then failing to reliable close or delete) 0-byte files.
• Ignoring OS-specific errors differentiating between non-ignorable invalid pathnames and ignorable filesystem issues. Unsurprisingly, this is critical under Windows. (See below.)
• Ignoring race conditions resulting from external processes concurrently (re)moving parent directories of the pathname to be tested. (See below.)
• Ignoring connection timeouts resulting from this pathname residing on stale, slow, or otherwise temporarily inaccessible filesystems. This could expose public-facing services to potential DoS-driven attacks. (See below.)

We're gonna fix all that.

Question #0: What's Pathname Validity Again?

Before hurling our fragile meat suits into the python-riddled moshpits of pain, we should probably define what we mean by "pathname validity." What defines validity, exactly?

By "pathname validity," we mean the syntactic correctness of a pathname with respect to the root filesystem of the current system – regardless of whether that path or parent directories thereof physically exist. A pathname is syntactically correct under this definition if it complies with all syntactic requirements of the root filesystem.

By "root filesystem," we mean:

• On POSIX-compatible systems, the filesystem mounted to the root directory (/).
• On Windows, the filesystem mounted to %HOMEDRIVE%, the colon-suffixed drive letter containing the current Windows installation (typically but not necessarily C:).

The meaning of "syntactic correctness," in turn, depends on the type of root filesystem. For ext4 (and most but not all POSIX-compatible) filesystems, a pathname is syntactically correct if and only if that pathname:

• Contains no null bytes (i.e., \x00 in Python). This is a hard requirement for all POSIX-compatible filesystems.
• Contains no path components longer than 255 bytes (e.g., 'a'*256 in Python). A path component is a longest substring of a pathname containing no / character (e.g., bergtatt, ind, i, and fjeldkamrene in the pathname /bergtatt/ind/i/fjeldkamrene).

Syntactic correctness. Root filesystem. That's it.

Question #1: How Now Shall We Do Pathname Validity?

Validating pathnames in Python is surprisingly non-intuitive. I'm in firm agreement with Fake Name here: the official os.path package should provide an out-of-the-box solution for this. For unknown (and probably uncompelling) reasons, it doesn't. Fortunately, unrolling your own ad-hoc solution isn't that gut-wrenching...

O.K., it actually is. It's hairy; it's nasty; it probably chortles as it burbles and giggles as it glows. But what you gonna do? Nuthin'.

We'll soon descend into the radioactive abyss of low-level code. But first, let's talk high-level shop. The standard os.stat() and os.lstat() functions raise the following exceptions when passed invalid pathnames:

• For pathnames residing in non-existing directories, instances of FileNotFoundError.
• For pathnames residing in existing directories:
  • Under Windows, instances of WindowsError whose winerror attribute is 123 (i.e., ERROR_INVALID_NAME).
  • Under all other OSes:
  • For pathnames containing null bytes (i.e., '\x00'), instances of TypeError.
  • For pathnames containing path components longer than 255 bytes, instances of OSError whose errcode attribute is:
    • Under SunOS and the *BSD family of OSes, errno.ERANGE. (This appears to be an OS-level bug, otherwise referred to as "selective interpretation" of the POSIX standard.)
    • Under all other OSes, errno.ENAMETOOLONG.

Crucially, this implies that only pathnames residing in existing directories are validatable. The os.stat() and os.lstat() functions raise generic FileNotFoundError exceptions when passed pathnames residing in non-existing directories, regardless of whether those pathnames are invalid or not. Directory existence takes precedence over pathname invalidity.

Does this mean that pathnames residing in non-existing directories are not validatable? Yes – unless we modify those pathnames to reside in existing directories. Is that even safely feasible, however? Shouldn't modifying a pathname prevent us from validating the original pathname?

To answer this question, recall from above that syntactically correct pathnames on the ext4 filesystem contain no path components (A) containing null bytes or (B) over 255 bytes in length. Hence, an ext4 pathname is valid if and only if all path components in that pathname are valid. This is true of most real-world filesystems of interest.

Does that pedantic insight actually help us? Yes. It reduces the larger problem of validating the full pathname in one fell swoop to the smaller problem of only validating all path components in that pathname. Any arbitrary pathname is validatable (regardless of whether that pathname resides in an existing directory or not) in a cross-platform manner by following the following algorithm:

1. Split that pathname into path components (e.g., the pathname /troldskog/faren/vild into the list ['', 'troldskog', 'faren', 'vild']).
2. For each such component:
   1. Join the pathname of a directory guaranteed to exist with that component into a new temporary pathname (e.g., /troldskog) .
   2. Pass that pathname to os.stat() or os.lstat(). If that pathname and hence that component is invalid, this call is guaranteed to raise an exception exposing the type of invalidity rather than a generic FileNotFoundError exception. Why? Because that pathname resides in an existing directory. (Circular logic is circular.)

Is there a directory guaranteed to exist? Yes, but typically only one: the topmost directory of the root filesystem (as defined above).

Passing pathnames residing in any other directory (and hence not guaranteed to exist) to os.stat() or os.lstat() invites race conditions, even if that directory was previously tested to exist. Why? Because external processes cannot be prevented from concurrently removing that directory after that test has been performed but before that pathname is passed to os.stat() or os.lstat(). Unleash the dogs of mind-fellating insanity!

There exists a substantial side benefit to the above approach as well: security. (Isn't that nice?) Specifically:

Front-facing applications validating arbitrary pathnames from untrusted sources by simply passing such pathnames to os.stat() or os.lstat() are susceptible to Denial of Service (DoS) attacks and other black-hat shenanigans. Malicious users may attempt to repeatedly validate pathnames residing on filesystems known to be stale or otherwise slow (e.g., NFS Samba shares); in that case, blindly statting incoming pathnames is liable to either eventually fail with connection timeouts or consume more time and resources than your feeble capacity to withstand unemployment.

The above approach obviates this by only validating the path components of a pathname against the root directory of the root filesystem. (If even that's stale, slow, or inaccessible, you've got larger problems than pathname validation.)

Lost? Great. Let's begin. (Python 3 assumed. See "What Is Fragile Hope for 300, leycec?")

Done. Don't squint at that code. (It bites.)

Question #2: Possibly Invalid Pathname Existence or Creatability, Eh?

Testing the existence or creatability of possibly invalid pathnames is, given the above solution, mostly trivial. The little key here is to call the previously defined function before testing the passed path:

def is_path_creatable(pathname: str) -> bool:
    '''
    `True` if the current user has sufficient permissions to create the passed
    pathname; `False` otherwise.
    '''
    # Parent directory of the passed path. If empty, we substitute the current
    # working directory (CWD) instead.
    dirname = os.path.dirname(pathname) or os.getcwd()
    return os.access(dirname, os.W_OK)

def is_path_exists_or_creatable(pathname: str) -> bool:
    '''
    `True` if the passed pathname is a valid pathname for the current OS _and_
    either currently exists or is hypothetically creatable; `False` otherwise.

    This function is guaranteed to _never_ raise exceptions.
    '''
    try:
        # To prevent "os" module calls from raising undesirable exceptions on
        # invalid pathnames, is_pathname_valid() is explicitly called first.
        return is_pathname_valid(pathname) and (
            os.path.exists(pathname) or is_path_creatable(pathname))
    # Report failure on non-fatal filesystem complaints (e.g., connection
    # timeouts, permissions issues) implying this path to be inaccessible. All
    # other exceptions are unrelated fatal issues and should not be caught here.
    except OSError:
        return False

Done and done. Except not quite.

Question #3: Possibly Invalid Pathname Existence or Writability on Windows

There exists a caveat. Of course there does.

As the official os.access() documentation admits:

Note: I/O operations may fail even when os.access() indicates that they would succeed, particularly for operations on network filesystems which may have permissions semantics beyond the usual POSIX permission-bit model.

To no one's surprise, Windows is the usual suspect here. Thanks to extensive use of Access Control Lists (ACL) on NTFS filesystems, the simplistic POSIX permission-bit model maps poorly to the underlying Windows reality. While this (arguably) isn't Python's fault, it might nonetheless be of concern for Windows-compatible applications.

If this is you, a more robust alternative is wanted. If the passed path does not exist, we instead attempt to create a temporary file guaranteed to be immediately deleted in the parent directory of that path – a more portable (if expensive) test of creatability:

import os, tempfile

def is_path_sibling_creatable(pathname: str) -> bool:
    '''
    `True` if the current user has sufficient permissions to create **siblings**
    (i.e., arbitrary files in the parent directory) of the passed pathname;
    `False` otherwise.
    '''
    # Parent directory of the passed path. If empty, we substitute the current
    # working directory (CWD) instead.
    dirname = os.path.dirname(pathname) or os.getcwd()

    try:
        # For safety, explicitly close and hence delete this temporary file
        # immediately after creating it in the passed path's parent directory.
        with tempfile.TemporaryFile(dir=dirname): pass
        return True
    # While the exact type of exception raised by the above function depends on
    # the current version of the Python interpreter, all such types subclass the
    # following exception superclass.
    except EnvironmentError:
        return False

def is_path_exists_or_creatable_portable(pathname: str) -> bool:
    '''
    `True` if the passed pathname is a valid pathname on the current OS _and_
    either currently exists or is hypothetically creatable in a cross-platform
    manner optimized for POSIX-unfriendly filesystems; `False` otherwise.

    This function is guaranteed to _never_ raise exceptions.
    '''
    try:
        # To prevent "os" module calls from raising undesirable exceptions on
        # invalid pathnames, is_pathname_valid() is explicitly called first.
        return is_pathname_valid(pathname) and (
            os.path.exists(pathname) or is_path_sibling_creatable(pathname))
    # Report failure on non-fatal filesystem complaints (e.g., connection
    # timeouts, permissions issues) implying this path to be inaccessible. All
    # other exceptions are unrelated fatal issues and should not be caught here.
    except OSError:
        return False

Note, however, that even this may not be enough.

Thanks to User Access Control (UAC), the ever-inimicable Windows Vista and all subsequent iterations thereof blatantly lie about permissions pertaining to system directories. When non-Administrator users attempt to create files in either the canonical C:\Windows or C:\Windows\system32 directories, UAC superficially permits the user to do so while actually isolating all created files into a "Virtual Store" in that user's profile. (Who could have possibly imagined that deceiving users would have harmful long-term consequences?)

This is crazy. This is Windows.

Prove It

Dare we? It's time to test-drive the above tests.

Since NULL is the only character prohibited in pathnames on UNIX-oriented filesystems, let's leverage that to demonstrate the cold, hard truth – ignoring non-ignorable Windows shenanigans, which frankly bore and anger me in equal measure:

>>> print('"foo.bar" valid? ' + str(is_pathname_valid('foo.bar')))
"foo.bar" valid? True
>>> print('Null byte valid? ' + str(is_pathname_valid('\x00')))
Null byte valid? False
>>> print('Long path valid? ' + str(is_pathname_valid('a' * 256)))
Long path valid? False
>>> print('"/dev" exists or creatable? ' + str(is_path_exists_or_creatable('/dev')))
"/dev" exists or creatable? True
>>> print('"/dev/foo.bar" exists or creatable? ' + str(is_path_exists_or_creatable('/dev/foo.bar')))
"/dev/foo.bar" exists or creatable? False
>>> print('Null byte exists or creatable? ' + str(is_path_exists_or_creatable('\x00')))
Null byte exists or creatable? False

Beyond sanity. Beyond pain. You will find Python portability concerns.

Since I consider it relevant and elegant enough (no need to specify coordinates to place text), I copy (with a slight adaptation) an answer to another related question.

import matplotlib.pyplot as plt
fig, axes = plt.subplots(5, 2, sharex=True, sharey=True, figsize=(6,15))
# add a big axis, hide frame
fig.add_subplot(111, frameon=False)
# hide tick and tick label of the big axis
plt.tick_params(labelcolor='none', top=False, bottom=False, left=False, right=False)
plt.xlabel("common X")
plt.ylabel("common Y")

This results in the following (with matplotlib version 2.2.0):

It doesn't recognize that you have a master branch, but I found a way to get around it. I found out that there's nothing special about a master branch, you can just create another branch and call it master branch and that's what I did.

To create a master branch:

git checkout -b master

And you can work off of that.

1. Firstly uninstall pyserial using the command pip uninstall pyserial
2. Then go to https://www.lfd.uci.edu/~gohlke/pythonlibs/
3. download the suitable pyserial version and then go to the directory where the file is downloaded and open cmd there
4. then type pip install "filename"(without quotes)

Use either toLowerCase or toLocaleLowerCase methods of the String object. The difference is that toLocaleLowerCase will take current locale of the user/host into account. As per § 15.5.4.17 of the ECMAScript Language Specification (ECMA-262), toLocaleLowerCase…

…works exactly the same as toLowerCase except that its result is intended to yield the correct result for the host environment’s current locale, rather than a locale-independent result. There will only be a difference in the few cases (such as Turkish) where the rules for that language conflict with the regular Unicode case mappings.

Example:

var lower = 'Your Name'.toLowerCase();

Also note that the toLowerCase and toLocaleLowerCase functions are implemented to work generically on any value type. Therefore you can invoke these functions even on non-String objects. Doing so will imply automatic conversion to a string value prior to changing the case of each character in the resulting string value. For example, you can apply toLowerCase directly on a date like this:

var lower = String.prototype.toLowerCase.apply(new Date());

and which is effectively equivalent to:

var lower = new Date().toString().toLowerCase();

The second form is generally preferred for its simplicity and readability. On earlier versions of IE, the first had the benefit that it could work with a null value. The result of applying toLowerCase or toLocaleLowerCase on null would yield null (and not an error condition).

As said Will Wagner, in old version of jsp you should always use c:out to output dynamic text.

Moreover, using this syntax:

<c:out value="${person.name}">No name</c:out>

you can display the text "No name" when name is null.

At the very core, the file extension you use makes no difference as to how perl interprets those files.

However, putting modules in .pm files following a certain directory structure that follows the package name provides a convenience. So, if you have a module Example::Plot::FourD and you put it in a directory Example/Plot/FourD.pm in a path in your @INC, then use and require will do the right thing when given the package name as in use Example::Plot::FourD.

The file must return true as the last statement to indicate successful execution of any initialization code, so it's customary to end such a file with 1; unless you're sure it'll return true otherwise. But it's better just to put the 1;, in case you add more statements.

If EXPR is a bareword, the require assumes a ".pm" extension and replaces "::" with "/" in the filename for you, to make it easy to load standard modules. This form of loading of modules does not risk altering your namespace.

All use does is to figure out the filename from the package name provided, require it in a BEGIN block and invoke import on the package. There is nothing preventing you from not using use but taking those steps manually.

For example, below I put the Example::Plot::FourD package in a file called t.pl, loaded it in a script in file s.pl.

C:\Temp> cat t.pl
package Example::Plot::FourD;

use strict; use warnings;

sub new { bless {} => shift }

sub something { print "something\n" }

"Example::Plot::FourD"

C:\Temp> cat s.pl
#!/usr/bin/perl
use strict; use warnings;

BEGIN {
    require 't.pl';
}

my $p = Example::Plot::FourD->new;
$p->something;


C:\Temp> s
something

This example shows that module files do not have to end in 1, any true value will do.

It might be obvious, but make sure that you are sending to the parser URL object not a String containing www adress. This will not work:

    ObjectMapper mapper = new ObjectMapper();
    String www = "www.sample.pl";
    Weather weather = mapper.readValue(www, Weather.class);

But this will:

    ObjectMapper mapper = new ObjectMapper();
    URL www = new URL("http://www.oracle.com/");
    Weather weather = mapper.readValue(www, Weather.class);

$() is the jQuery constructor function.

this is a reference to the DOM element of invocation.

So basically, in $(this), you are just passing the this in $() as a parameter so that you could call jQuery methods and functions.

Do not use authorization instead of authentication. I should get whole access to service all clients with header. The working code is :

public class TokenAuthenticationHandler : AuthenticationHandler<TokenAuthenticationOptions> 
{
    public IServiceProvider ServiceProvider { get; set; }

    public TokenAuthenticationHandler (IOptionsMonitor<TokenAuthenticationOptions> options, ILoggerFactory logger, UrlEncoder encoder, ISystemClock clock, IServiceProvider serviceProvider) 
        : base (options, logger, encoder, clock) 
    {
        ServiceProvider = serviceProvider;
    }

    protected override Task<AuthenticateResult> HandleAuthenticateAsync () 
    {
        var headers = Request.Headers;
        var token = "X-Auth-Token".GetHeaderOrCookieValue (Request);

        if (string.IsNullOrEmpty (token)) {
            return Task.FromResult (AuthenticateResult.Fail ("Token is null"));
        }           

        bool isValidToken = false; // check token here

        if (!isValidToken) {
            return Task.FromResult (AuthenticateResult.Fail ($"Balancer not authorize token : for token={token}"));
        }

        var claims = new [] { new Claim ("token", token) };
        var identity = new ClaimsIdentity (claims, nameof (TokenAuthenticationHandler));
        var ticket = new AuthenticationTicket (new ClaimsPrincipal (identity), this.Scheme.Name);
        return Task.FromResult (AuthenticateResult.Success (ticket));
    }
}

Startup.cs :

#region Authentication
services.AddAuthentication (o => {
    o.DefaultScheme = SchemesNamesConst.TokenAuthenticationDefaultScheme;
})
.AddScheme<TokenAuthenticationOptions, TokenAuthenticationHandler> (SchemesNamesConst.TokenAuthenticationDefaultScheme, o => { });
#endregion

And mycontroller.cs

[Authorize(AuthenticationSchemes = SchemesNamesConst.TokenAuthenticationDefaultScheme)]
public class MainController : BaseController
{ ... }

I can't find TokenAuthenticationOptions now, but it was empty. I found the same class PhoneNumberAuthenticationOptions :

public class PhoneNumberAuthenticationOptions : AuthenticationSchemeOptions
{
    public Regex PhoneMask { get; set; }// = new Regex("7\\d{10}");
}

You should define static class SchemesNamesConst. Something like:

public static class SchemesNamesConst
{
    public const string TokenAuthenticationDefaultScheme = "TokenAuthenticationScheme";
}

I check length.

if (str.length == 0) {
}

You can do it without root permissions:

cat srcfile > /mnt/sdcard/dstfile

I like

if ('string'[/^str/]) ...

"How can I directly (without saving the file on 2nd server) download the file from 1st server to client's machine?"

Just use the Client API and get the InputStream from the response

Client client = ClientBuilder.newClient();
String url = "...";
final InputStream responseStream = client.target(url).request().get(InputStream.class);

There are two flavors to get the InputStream. You can also use

Response response = client.target(url).request().get();
InputStream is = (InputStream)response.getEntity();

Which one is the more efficient? I'm not sure, but the returned InputStreams are different classes, so you may want to look into that if you care to.

From 2nd server I can get a ByteArrayOutputStream to get the file from 1st server, can I pass this stream further to the client using the REST service?

So most of the answers you'll see in the link provided by @GradyGCooper seem to favor the use of StreamingOutput. An example implementation might be something like

final InputStream responseStream = client.target(url).request().get(InputStream.class);
System.out.println(responseStream.getClass());
StreamingOutput output = new StreamingOutput() {
    @Override
    public void write(OutputStream out) throws IOException, WebApplicationException {  
        int length;
        byte[] buffer = new byte[1024];
        while((length = responseStream.read(buffer)) != -1) {
            out.write(buffer, 0, length);
        }
        out.flush();
        responseStream.close();
    }   
};
return Response.ok(output).header(
        "Content-Disposition", "attachment, filename=\"...\"").build();

But if we look at the source code for StreamingOutputProvider, you'll see in the writeTo, that it simply writes the data from one stream to another. So with our implementation above, we have to write twice.

How can we get only one write? Simple return the InputStream as the Response

final InputStream responseStream = client.target(url).request().get(InputStream.class);
return Response.ok(responseStream).header(
        "Content-Disposition", "attachment, filename=\"...\"").build();

If we look at the source code for InputStreamProvider, it simply delegates to ReadWriter.writeTo(in, out), which simply does what we did above in the StreamingOutput implementation

 public static void writeTo(InputStream in, OutputStream out) throws IOException {
    int read;
    final byte[] data = new byte[BUFFER_SIZE];
    while ((read = in.read(data)) != -1) {
        out.write(data, 0, read);
    }
}

Asides:

• Client objects are expensive resources. You may want to reuse the same Client for request. You can extract a WebTarget from the client for each request.

  WebTarget target = client.target(url);
  InputStream is = target.request().get(InputStream.class);
  

  I think the WebTarget can even be shared. I can't find anything in the Jersey 2.x documentation (only because it is a larger document, and I'm too lazy to scan through it right now :-), but in the Jersey 1.x documentation, it says the Client and WebResource (which is equivalent to WebTarget in 2.x) can be shared between threads. So I'm guessing Jersey 2.x would be the same. but you may want to confirm for yourself.

• You don't have to make use of the Client API. A download can be easily achieved with the java.net package APIs. But since you're already using Jersey, it doesn't hurt to use its APIs

• The above is assuming Jersey 2.x. For Jersey 1.x, a simple Google search should get you a bunch of hits for working with the API (or the documentation I linked to above)

UPDATE

I'm such a dufus. While the OP and I are contemplating ways to turn a ByteArrayOutputStream to an InputStream, I missed the simplest solution, which is simply to write a MessageBodyWriter for the ByteArrayOutputStream

import java.io.ByteArrayOutputStream;
import java.io.IOException;
import java.io.OutputStream;
import java.lang.annotation.Annotation;
import java.lang.reflect.Type;
import javax.ws.rs.WebApplicationException;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.MultivaluedMap;
import javax.ws.rs.ext.MessageBodyWriter;
import javax.ws.rs.ext.Provider;

@Provider
public class OutputStreamWriter implements MessageBodyWriter<ByteArrayOutputStream> {

    @Override
    public boolean isWriteable(Class<?> type, Type genericType,
            Annotation[] annotations, MediaType mediaType) {
        return ByteArrayOutputStream.class == type;
    }

    @Override
    public long getSize(ByteArrayOutputStream t, Class<?> type, Type genericType,
            Annotation[] annotations, MediaType mediaType) {
        return -1;
    }

    @Override
    public void writeTo(ByteArrayOutputStream t, Class<?> type, Type genericType,
            Annotation[] annotations, MediaType mediaType,
            MultivaluedMap<String, Object> httpHeaders, OutputStream entityStream)
            throws IOException, WebApplicationException {
        t.writeTo(entityStream);
    }
}

Then we can simply return the ByteArrayOutputStream in the response

return Response.ok(baos).build();

D'OH!

UPDATE 2

Here are the tests I used (

Resource class

@Path("test")
public class TestResource {

    final String path = "some_150_mb_file";

    @GET
    @Produces(MediaType.APPLICATION_OCTET_STREAM)
    public Response doTest() throws Exception {
        InputStream is = new FileInputStream(path);
        ByteArrayOutputStream baos = new ByteArrayOutputStream();
        int len;
        byte[] buffer = new byte[4096];
        while ((len = is.read(buffer, 0, buffer.length)) != -1) {
            baos.write(buffer, 0, len);
        }
        System.out.println("Server size: " + baos.size());
        return Response.ok(baos).build();
    }
}

Client test

public class Main {
    public static void main(String[] args) throws Exception {
        Client client = ClientBuilder.newClient();
        String url = "http://localhost:8080/api/test";
        Response response = client.target(url).request().get();
        String location = "some_location";
        FileOutputStream out = new FileOutputStream(location);
        InputStream is = (InputStream)response.getEntity();
        int len = 0;
        byte[] buffer = new byte[4096];
        while((len = is.read(buffer)) != -1) {
            out.write(buffer, 0, len);
        }
        out.flush();
        out.close();
        is.close();
    }
}

UPDATE 3

So the final solution for this particular use case was for the OP to simply pass the OutputStream from the StreamingOutput's write method. Seems the third-party API, required a OutputStream as an argument.

StreamingOutput output = new StreamingOutput() {
    @Override
    public void write(OutputStream out) {
        thirdPartyApi.downloadFile(.., .., .., out);
    }
}
return Response.ok(output).build();

Not quite sure, but seems the reading/writing within the resource method, using ByteArrayOutputStream`, realized something into memory.

The point of the downloadFile method accepting an OutputStream is so that it can write the result directly to the OutputStream provided. For instance a FileOutputStream, if you wrote it to file, while the download is coming in, it would get directly streamed to the file.

It's not meant for us to keep a reference to the OutputStream, as you were trying to do with the baos, which is where the memory realization comes in.

So with the way that works, we are writing directly to the response stream provided for us. The method write doesn't actually get called until the writeTo method (in the MessageBodyWriter), where the OutputStream is passed to it.

You can get a better picture looking at the MessageBodyWriter I wrote. Basically in the writeTo method, replace the ByteArrayOutputStream with StreamingOutput, then inside the method, call streamingOutput.write(entityStream). You can see the link I provided in the earlier part of the answer, where I link to the StreamingOutputProvider. This is exactly what happens

To set focus,

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs)
    TextBox1.Focus()
End Sub

Set the TabIndex by

Me.TextBox1.TabIndex = 0

If script execution order is not the issue, another possible cause of the problem is that the element is not being selected properly:

• getElementById requires the passed string to be the ID verbatim, and nothing else. If you prefix the passed string with a #, and the ID does not start with a #, nothing will be selected:

    <div id="foo"></div>
  

    // Error, selected element will be null:
    document.getElementById('#foo')
    // Fix:
    document.getElementById('foo')
  

• Similarly, for getElementsByClassName, don't prefix the passed string with a .:

    <div class="bar"></div>
  

    // Error, selected element will be undefined:
    document.getElementsByClassName('.bar')[0]
    // Fix:
    document.getElementsByClassName('bar')[0]
  

• With querySelector, querySelectorAll, and jQuery, to match an element with a particular class name, put a . directly before the class. Similarly, to match an element with a particular ID, put a # directly before the ID:

    <div class="baz"></div>
  

    // Error, selected element will be null:
    document.querySelector('baz')
    $('baz')
    // Fix:
    document.querySelector('.baz')
    $('.baz')
  

  The rules here are, in most cases, identical to those for CSS selectors, and can be seen in detail here.

• To match an element which has two or more attributes (like two class names, or a class name and a data- attribute), put the selectors for each attribute next to each other in the selector string, without a space separating them (because a space indicates the descendant selector). For example, to select:

    <div class="foo bar"></div>
  

  use the query string .foo.bar. To select

    <div class="foo" data-bar="someData"></div>
  

  use the query string .foo[data-bar="someData"]. To select the <span> below:

    <div class="parent">
      <span data-username="bob"></span>
    </div>
  

  use div.parent > span[data-username="bob"].

• Capitalization and spelling does matter for all of the above. If the capitalization is different, or the spelling is different, the element will not be selected:

    <div class="result"></div>
  

    // Error, selected element will be null:
    document.querySelector('.results')
    $('.Result')
    // Fix:
    document.querySelector('.result')
    $('.result')
  

• You also need to make sure the methods have the proper capitalization and spelling. Use one of:

  $(selector)
  document.querySelector
  document.querySelectorAll
  document.getElementsByClassName
  document.getElementsByTagName
  document.getElementById
  

  Any other spelling or capitalization will not work. For example, document.getElementByClassName will throw an error.

• Make sure you pass a string to these selector methods. If you pass something that isn't a string to querySelector, getElementById, etc, it almost certainly won't work.

• If the HTML attributes on elements you want to select are surrounded by quotes, they must be plain straight quotes (either single or double); curly quotes like ‘ or ” will not work if you're trying to select by ID, class, or attribute.

You can do it this way:

=IF(E9>21,"Text 1",IF(AND(E9>=5,E9<=21),"Test 2","Text 3"))

Note I assume you meant >= and <= here since your description skipped the values 5 and 21, but you can adjust these inequalities as needed.

Or you can do it this way:

=IF(E9>21,"Text 1",IF(E9<5,"Text 3","Text 2"))

This is worked for me.. Make sure you typed nib name correctly.

[[NSBundle mainBundle]loadNibNamed:@"Graphview" owner:self options:nil];

Graphview(nib name)

Use the following:

$("select").attr("disabled", "disabled");

Or simply add id="pizza_kind" to <select> tag, like <select name="pizza_kind" id="pizza_kind">: jsfiddle link

The reason your code didn't work is simply because $("#pizza_kind") isn't selecting the <select> element because it does not have id="pizza_kind".

Edit: actually, a better selector is $("select[name='pizza_kind']"): jsfiddle link

You could try

NumberUtils.isParsable(yourInput)

It is part of org/apache/commons/lang3/math/NumberUtils and it checks whether the string can be parsed by Integer.parseInt(String), Long.parseLong(String), Float.parseFloat(String) or Double.parseDouble(String).

See below:

https://commons.apache.org/proper/commons-lang/apidocs/org/apache/commons/lang3/math/NumberUtils.html#isParsable-java.lang.String-

It normally means an un-aligned access.

An attempt to access memory that isn't physically present would also give a bus error, but you won't see this if you're using a processor with an MMU and an OS that's not buggy, because you won't have any non-existent memory mapped to your process's address space.

If you need async: false in your ajax, you should use success instead of .done. Else you better to use .done. This is from jQuery official site:

As of jQuery 1.8, the use of async: false with jqXHR ($.Deferred) is deprecated; you must use the success/error/complete callback options instead of the corresponding methods of the jqXHR object such as jqXHR.done().

You need to run the function in the page the form is sent to.

I'll start with the answer then context NOTE this fix was logged above, I'm just re-stating it for anyone googling.

1. Download the source code of php 7 and extract it.
2. open your terminal
3. swim to the ext/pdo_mysql directory

4. use commands:

   phpize

   ./configure

   make

   make install (as root)

5. enable extension=mysqli.so in your php.ini file

apt-get install php7.0-mysql

Result:

Package 'php7.0-mysql' has no installation candidate

Get instructions saying all I have to do is run this:

add-apt-repository -y ppa:ondrej/apache2

But then I get this:

UnicodeDecodeError: 'ascii' codec can't decode byte 0xc5 in position 223: ordinal not in range(128)

So I try and force some type of UTF: LC_ALL=C.UTF-8 add-apt-repository -y ppa:ondrej/apache2 and I get this: no valid OpenPGP data found.

Follow some other instructions to run this: apt-get update and I get this: Err:14 http://ppa.launchpad.net/ondrej/apache2/ubuntu cosmic/main amd64 Packages 404 Not Found Err:15 http://ppa.launchpad.net/ondrej/php/ubuntu cosmic/main amd64 Packages 404 Not Found and - I think because of that - I then get:

The repository 'http://ppa.launchpad.net/ondrej/apache2/ubuntu cosmic Release' does not have a Release file.

By this stage, I'm still getting this on apt-get update:

Package 'php7.0-mysql' has no installation candidate.

I start trying to add in php libraries, got Unicode issues, tried to get around that and.... you get the idea... whack-a-mole. I gave up and looked to see if I could compile it and I found the answer I started with.

You might be wondering why I wrote so much? So that anyone googling can find this solution (including me!).

Since the title didn't specify that it has to be programmatic I'll assume that it was a genuine debugging/privacy management issue and solution is browser dependent and requires a browser with built in detailed cookie management toll and/or a debugging module or a plug-in/extension. I'm going to list one and ask other people to write up on browsers they know in detail and please be precise with versions.

Chromium, Iron build (SRWare Iron 4.0.280)

The wrench(tool) menu: Options / Under The Hood / [Show cookies and website permissions] For related domains/sites type the suffix into the search box (like .foo.tv). Caveat: when you have a node (site or cookie) click-highlighted only use [Remove] to kill specific subtrees. Using [Remove All] will still delete cookies for all sites selected by search and waste your debugging session.

Tensorflow 2.2.0 supports Python3.8

First, make sure to install Python 3.8 64bit. For some reason, the official site defaults to 32bit. Verify this using python -VV (two capital V, not W). Then continue as usual:

python -m pip install --upgrade pip
python -m pip install wheel  # not necessary
python -m pip install tensorflow

As usual, make sure you have CUDA 10.1 and CuDNN installed.

You can try this:

td p {word-break:break-all;}

This, however, makes it appear like this when there's enough space, unless you add a <br> tag:

aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb

So, I would then suggest adding <br> tags where there are newlines, if possible.

aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb

The above answers give a good insight on how to delete the "Cars"

However, I want this answer to challenge the approach itself:

1- SQLite CoreData is a relational database. In this case, where there isn't any releation, I would advise against using CoreData and maybe using the file system instead, or keep things in memory.

2- In other examples, where "Car" entity have other relations, and therefore CoreData, I would advise against having 2000 cars as root entity. Instead I would give them a parent, let's say "CarsRepository" entity. Then you can give a one-to-many relationship to the "Car" entity, and just replace the relationship to point to the new cars when they are downloaded. Adding the right deletion rule to the relationships ensures the integrity of the model.

The simplest solution is to select the second cell, and press =. This will begin the fomula creation process. Now either type in the 1st cell reference (eg, A1) or click on the first cell and press enter. This should make the second cell reference the value of the first cell.

I was getting same issue, I did every thing correct excepted in xml file:

• step first 1: initialize recyclerview & List & Adaptor:

  RecyclerView recyclerview;
  List<ModelName> list;
  ProvideBidAdaptor adaptor;
  

• step 2: bind it in onCreate-

  recyclerview = findByViewId(R.id.providerBidRV);
  recyclerview.setLayoutManager(new LinearLayoutManager(this));
  recyclerview.setHasFixedSize(true);
  list = new ArrayList<>();
  

• step 3: Where you getting response or list - add list- (i am getting from response)>

  responseList.addAll(response.getResponse());
  adaptor = new ProvideBidAdaptor(this, responseList);
  binding.detailsRV.setAdapter(adaptor);
  

Here is my xml file where i implement RecyclerView: I was forget orientation in LinearLayout, after this correction- RecyclerView attached.

<?xml version="1.0" encoding="utf-8"?>
    <layout>
    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:app="http://schemas.android.com/apk/res-auto"
        xmlns:tools="http://schemas.android.com/tools"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical"
        tools:context=".activities.Bidding.ProvideBid">

        <include
            android:id="@+id/toolbar"
            layout="@layout/app_toolbar"/>

        <androidx.recyclerview.widget.RecyclerView
            android:id="@+id/providerBidRV"
            android:layout_width="match_parent"
            android:layout_height="match_parent"/>
    </LinearLayout>
</layout> 

Here is Adaptor:

    public class ProvideBidAdaptor extends RecyclerView.Adapter<ProvideBidAdaptor.ViewHolder> {
    Context context;
    List<Response> responseList;
    DateTime dateTimeInstance = new DateTime();

    public ProvideBidAdaptor(Context context, List<Response> responseList) {
        this.context = context;
        this.responseList = responseList;
    }

    @NonNull
    @Override
    public ViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
        View view = LayoutInflater.from(context).inflate(R.layout.geo_presence_item_list, parent, false);
        return new ViewHolder(view);
    }

    @Override
    public void onBindViewHolder(@NonNull ViewHolder holder, int position) {
        final Response detailsResponse = responseList.get(position);
        if (!detailsResponse.getUserId().isEmpty()) {

            holder.day.setText(detailsResponse.getDay());
            holder.locationType.setText(detailsResponse.getLocationType());

        }

    }

    @Override
    public int getItemCount() {
        return responseList.size();
    }

    public class ViewHolder extends RecyclerView.ViewHolder {
        TextView date,locationType;
        CardView provideBidCV;
        LinearLayout dayLLayout,locationTypeLLayout;
        public ViewHolder(@NonNull View itemView) {
            super(itemView);
            date = itemView.findViewById(R.id.date_value);
            day = itemView.findViewById(R.id.day_value);
            locationType = itemView.findViewById(R.id.locationType_value);

            locationTypeLLayout = itemView.findViewById(R.id.locationTypeLLayout);

        }
    }
}

var payeeCountry = document.getElementById( "payeeCountry" );
alert( payeeCountry.options[ yourSelect.selectedIndex ].value );

I'm now using RxJS 5.5.7 in an Angular application and using finalize operator has a weird behavior for my use case since is fired before success or error callbacks.

Simple example:

// Simulate an AJAX callback...
of(null)
  .pipe(
    delay(2000),
    finalize(() => {
      // Do some work after complete...
      console.log('Finalize method executed before "Data available" (or error thrown)');
    })
  )
  .subscribe(
      response => {
        console.log('Data available.');
      },
      err => {
        console.error(err);
      }
  );

I have had to use the add medhod in the subscription to accomplish what I want. Basically a finally callback after the success or error callbacks are done. Like a try..catch..finally block or Promise.finally method.

Simple example:

// Simulate an AJAX callback...
of(null)
  .pipe(
    delay(2000)
  )
  .subscribe(
      response => {
        console.log('Data available.');
      },
      err => {
        console.error(err);
      }
  );
  .add(() => {
    // Do some work after complete...
    console.log('At this point the success or error callbacks has been completed.');
  });

I previously had this problem with my EC2 instance (I was serving couchdb to serve resources -- am considering Amazon's S3 for the future).

One thing to check (assuming Ec2) is that the couchdb port is added to your open ports within your security policy.

I specifically encountered

"[Errno 111] Connection refused"

over EC2 when the instance was stopped and started. The problem seems to be a pidfile race. The solution for me was killing couchdb (entirely and properly) via:

pkill -f couchdb

and then restarting with:

/etc/init.d/couchdb restart

Here is a code snippet taken from a blog article written by Anubhav Goyal:

// this code will mark the forms authentication cookie and the
// session cookie as Secure.
if (Response.Cookies.Count > 0)
{
    foreach (string s in Response.Cookies.AllKeys)
    {
        if (s == FormsAuthentication.FormsCookieName || "asp.net_sessionid".Equals(s, StringComparison.InvariantCultureIgnoreCase))
        {
             Response.Cookies[s].Secure = true;
        }
    }
}

Adding this to the EndRequest event handler in the global.asax should make this happen for all page calls.

Note: An edit was proposed to add a break; statement inside a successful "secure" assignment. I've rejected this edit based on the idea that it would only allow 1 of the cookies to be forced to secure and the second would be ignored. It is not inconceivable to add a counter or some other metric to determine that both have been secured and to break at that point.

I was in such situation .. and found This:

int ColumnIndex = DataGrid.CurrentColumn.DisplayIndex;
TextBlock CellContent = DataGrid.SelectedCells[ColumnIndex].Column.GetCellContent(DataGrid.SelectedItem);

And make sure to treat custom columns' templates

You can get the DOM element and set disabled attribute to true/false.

If you use vue framework,here is a very easy demo.

  let vm = new Vue({
        el: "#app",
        data() {
            return { flag: true }
        },
        computed: {
            btnText() {
                return this.flag ? "Enable" : "Disable";
            }
        }
    })

<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"></script>

<div id="app">
    <input type="text" value="something" :disabled="flag" />
    <input type="button" :value="btnText" @click="flag=!flag">
</div>

XmlDocument is great for developers who are familiar with the XML DOM object model. It's been around for a while, and more or less corresponds to a W3C standard. It supports manual navigation as well as XPath node selection.

XDocument powers the LINQ to XML feature in .NET 3.5. It makes heavy use of IEnumerable<> and can be easier to work with in straight C#.

Both document models require you to load the entire document into memory (unlike XmlReader for example).

You have to use eval() to execute any script code that you've inserted as DOM text.

MooTools will do this for you automatically, and I'm sure jQuery would as well (depending on the version. jQuery version 1.6+ uses eval). This saves a lot of hassle of parsing out <script> tags and escaping your content, as well as a bunch of other "gotchas".

Generally if you're going to eval() it yourself, you want to create/send the script code without any HTML markup such as <script>, as these will not eval() properly.

If you are dealing with more dynamic screen resolution/sizes, instead of hardcoding the size in pixels you can change the width to a percentage of the media width as such

@media (min-width: 1200px) {
    .container{
        max-width: 70%;
   }
}

Here is an example. Green square is parent and yellow square is child element.

The input type=email page of the www.w3.org site notes that an email address is any string which matches the following regular expression:

/^[a-zA-Z0-9.!#$%&’*+/=?^_`{|}~-]+@[a-zA-Z0-9-]+(?:\.[a-zA-Z0-9-]+)*$/

Use the required attribute and a pattern attribute to require the value to match the regex pattern.

<input
    type="text"
    pattern="/^[a-zA-Z0-9.!#$%&’*+/=?^_`{|}~-]+@[a-zA-Z0-9-]+(?:\.[a-zA-Z0-9-]+)*$/"
    required
>

Try this one

 public static void main(String[] args) 
{
     int x=11;
     int y=x/2; // spaces
     int z=1; // *`s

     for(int i=0;i<5;i++)
    {
         for(int j=0;j<y;j++)
        {
             System.out.print(" ");
        }
        for(int k=0;k<z;k++)
        {
            System.out.print("*");
        }

        y=y-1;
        z=z+2;
        System.out.println();  
    }

}

Yes, it's true. Why do you doubt the php faq on the function? :)

The result of running password_hash() has has four parts:

1. the algorithm used
2. parameters
3. salt
4. actual password hash

So as you can see, the hash is a part of it.

Sure, you could have an additional salt for an added layer of security, but I honestly think that's overkill in a regular php application. The default bcrypt algorithm is good, and the optional blowfish one is arguably even better.

This solution avoids iteration, works for both +ve and -ve weekday differences and includes a unit test suite to regression against the slower method of counting weekdays. I've also include a concise method to add weekdays also works in the same non-iterative way.

Unit tests cover a few thousand date combinations in order to exhaustively test all start/end weekday combinations with both small and large date ranges.

Important: We make the assumption that we are counting days by excluding the start date and including the end date. This is important when counting weekdays as the specific start/end days that you include/exclude affect the result. This also ensures that the difference between two equal days is always zero and that we only include full working days as typically you want the answer to be correct for any time on the current start date (often today) and include the full end date (e.g. a due date).

NOTE: This code needs an additional adjustment for holidays but in keeping with the above assumption, this code must exclude holidays on the start date.

Add weekdays:

private static readonly int[,] _addOffset = 
{
  // 0  1  2  3  4
    {0, 1, 2, 3, 4}, // Su  0
    {0, 1, 2, 3, 4}, // M   1
    {0, 1, 2, 3, 6}, // Tu  2
    {0, 1, 4, 5, 6}, // W   3
    {0, 1, 4, 5, 6}, // Th  4
    {0, 3, 4, 5, 6}, // F   5
    {0, 2, 3, 4, 5}, // Sa  6
};

public static DateTime AddWeekdays(this DateTime date, int weekdays)
{
    int extraDays = weekdays % 5;
    int addDays = weekdays >= 0
        ? (weekdays / 5) * 7 + _addOffset[(int)date.DayOfWeek, extraDays]
        : (weekdays / 5) * 7 - _addOffset[6 - (int)date.DayOfWeek, -extraDays];
    return date.AddDays(addDays);
}

Compute weekday difference:

static readonly int[,] _diffOffset = 
{
  // Su M  Tu W  Th F  Sa
    {0, 1, 2, 3, 4, 5, 5}, // Su
    {4, 0, 1, 2, 3, 4, 4}, // M 
    {3, 4, 0, 1, 2, 3, 3}, // Tu
    {2, 3, 4, 0, 1, 2, 2}, // W 
    {1, 2, 3, 4, 0, 1, 1}, // Th
    {0, 1, 2, 3, 4, 0, 0}, // F 
    {0, 1, 2, 3, 4, 5, 0}, // Sa
};

public static int GetWeekdaysDiff(this DateTime dtStart, DateTime dtEnd)
{
    int daysDiff = (int)(dtEnd - dtStart).TotalDays;
    return daysDiff >= 0
        ? 5 * (daysDiff / 7) + _diffOffset[(int) dtStart.DayOfWeek, (int) dtEnd.DayOfWeek]
        : 5 * (daysDiff / 7) - _diffOffset[6 - (int) dtStart.DayOfWeek, 6 - (int) dtEnd.DayOfWeek];
}

I found that most other solutions on stack overflow were either slow (iterative) or overly complex and many were just plain incorrect. Moral of the story is ... Don't trust it unless you've exhaustively tested it!!

I spent over 3 hours to find out solution. Actually port 80 was being used by "system" service so I tried to change port from 80 to 8080 in "httpd" file but same problem raised "port 80 is used by system". It had driven me mad for 3 hours as every thing was changed like port , localhost server etc pointing to 8080.

At last I found mistake that was server root. Basically "Server Root" in "httpd" should be pointing to apache foler of xampp. In my case that's was

ServerRoot "xampp/apache"

I just changed it as follows:

ServerRoot "C:/xampp/apache" 

It has worked successfully and now everything is running with OK status.

wmode=opaque or transparent at the beginning of my query string didnt solve anything. This issue for me only occurs on Chrome, and not across even all computers. Just one cpu. It occurs in vimeo embeds as well, and possibly others.

My solution to to attach to the 'shown' and 'hidden' event of the bootstrap modals I am using, add a class which sets the iframe to 1x1 pixels, and remove the class when the modal closes. Seems like it works and is simple to implement.

Here is a quick start to get the gears turning...

ParkingLot is a class.

ParkingSpace is a class.

ParkingSpace has an Entrance.

Entrance has a location or more specifically, distance from Entrance.

ParkingLotSign is a class.

ParkingLot has a ParkingLotSign.

ParkingLot has a finite number of ParkingSpaces.

HandicappedParkingSpace is a subclass of ParkingSpace.

RegularParkingSpace is a subclass of ParkingSpace.

CompactParkingSpace is a subclass of ParkingSpace.

ParkingLot keeps array of ParkingSpaces, and a separate array of vacant ParkingSpaces in order of distance from its Entrance.

ParkingLotSign can be told to display "full", or "empty", or "blank/normal/partially occupied" by calling .Full(), .Empty() or .Normal()

Parker is a class.

Parker can Park().

Parker can Unpark().

Valet is a subclass of Parker that can call ParkingLot.FindVacantSpaceNearestEntrance(), which returns a ParkingSpace.

Parker has a ParkingSpace.

Parker can call ParkingSpace.Take() and ParkingSpace.Vacate().

Parker calls Entrance.Entering() and Entrance.Exiting() and ParkingSpace notifies ParkingLot when it is taken or vacated so that ParkingLot can determine if it is full or not. If it is newly full or newly empty or newly not full or empty, it should change the ParkingLotSign.Full() or ParkingLotSign.Empty() or ParkingLotSign.Normal().

HandicappedParker could be a subclass of Parker and CompactParker a subclass of Parker and RegularParker a subclass of Parker. (might be overkill, actually.)

In this solution, it is possible that Parker should be renamed to be Car.

Not sure as cant see it in steps you mentioned.

Another alternative is KMP (Knuth–Morris–Pratt).

The KMP algorithm searches for a length-m substring in a length-n string in worst-case O(n+m) time, compared to a worst-case of O(n·m) for the naive algorithm, so using KMP may be reasonable if you care about worst-case time complexity.

Here's a JavaScript implementation by Project Nayuki, taken from https://www.nayuki.io/res/knuth-morris-pratt-string-matching/kmp-string-matcher.js:

// Searches for the given pattern string in the given text string using the Knuth-Morris-Pratt string matching algorithm.
// If the pattern is found, this returns the index of the start of the earliest match in 'text'. Otherwise -1 is returned.

function kmpSearch(pattern, text) {_x000D_
  if (pattern.length == 0)_x000D_
    return 0; // Immediate match_x000D_
_x000D_
  // Compute longest suffix-prefix table_x000D_
  var lsp = [0]; // Base case_x000D_
  for (var i = 1; i < pattern.length; i++) {_x000D_
    var j = lsp[i - 1]; // Start by assuming we're extending the previous LSP_x000D_
    while (j > 0 && pattern.charAt(i) != pattern.charAt(j))_x000D_
      j = lsp[j - 1];_x000D_
    if (pattern.charAt(i) == pattern.charAt(j))_x000D_
      j++;_x000D_
    lsp.push(j);_x000D_
  }_x000D_
_x000D_
  // Walk through text string_x000D_
  var j = 0; // Number of chars matched in pattern_x000D_
  for (var i = 0; i < text.length; i++) {_x000D_
    while (j > 0 && text.charAt(i) != pattern.charAt(j))_x000D_
      j = lsp[j - 1]; // Fall back in the pattern_x000D_
    if (text.charAt(i) == pattern.charAt(j)) {_x000D_
      j++; // Next char matched, increment position_x000D_
      if (j == pattern.length)_x000D_
        return i - (j - 1);_x000D_
    }_x000D_
  }_x000D_
  return -1; // Not found_x000D_
}_x000D_
_x000D_
console.log(kmpSearch('ays', 'haystack') != -1) // true_x000D_
console.log(kmpSearch('asdf', 'haystack') != -1) // false

You get the index number of the row in the datagridview using northwind database employees tables as an example:

using System;
using System.Windows.Forms;

namespace WindowsFormsApplication5
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            // TODO: This line of code loads data into the 'nORTHWNDDataSet.Employees' table. You can move, or remove it, as needed.
            this.employeesTableAdapter.Fill(this.nORTHWNDDataSet.Employees);

        }

        private void dataGridView1_CellDoubleClick(object sender, DataGridViewCellEventArgs e)
        {
            var dataIndexNo = dataGridView1.Rows[e.RowIndex].Index.ToString();
            string cellValue = dataGridView1.Rows[e.RowIndex].Cells[1].Value.ToString();

            MessageBox.Show("The row index = " + dataIndexNo.ToString() + " and the row data in second column is: "
                + cellValue.ToString());
        }
    }
}

the result will show you index number of record and the contents of the second table column in datagridview:

import Foundation
import CoreLocation

enum Result<T> {
  case success(T)
  case failure(Error)
}

final class LocationService: NSObject {

    }

}

 extension LocationService: CLLocationManagerDelegate {
    func locationManager(_ manager: CLLocationManager, didFailWithError error: Error) {
        newLocation?(.failure(error))
        manager.stopUpdatingLocation()
    }

    func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
        if let location = locations.sorted(by: {$0.timestamp > $1.timestamp}).first {
            newLocation?(.success(location))
        }
        manager.stopUpdatingLocation()
    }

    func locationManager(_ manager: CLLocationManager, didChangeAuthorization status: CLAuthorizationStatus) {
        switch status {
        case .notDetermined, .restricted, .denied:
            didChangeStatus?(false)
        default:
            didChangeStatus?(true)
        }
    }
}

Needs to write this code in required ViewController.

                    self.displayLocationInfo(pmark)
                } else {
                    print("Problem with the data received from geocoder")
                }
            })
        case .failure(let error):

Nicely explained above!

For all those who may suffer like me to get this working in a localized Windows (mine is XP in Slovak), you may try to replace the % with a !

So:

SET TEXT=Hello World
SET SUBSTRING=!TEXT:~3,5!
ECHO !SUBSTRING!

Try like this:

$data = array('current_login' => date('Y-m-d H:i:s'));
$this->db->set('last_login', 'current_login', false);
$this->db->where('id', 'some_id');
$this->db->update('login_table', $data);

Pay particular attention to the set() call's 3rd parameter. false prevents CodeIgniter from quoting the 2nd parameter -- this allows the value to be treated as a table column and not a string value. For any data that doesn't need to special treatment, you can lump all of those declarations into the $data array.

The query generated by above code:

UPDATE `login_table`
SET last_login = current_login, `current_login` = '2018-01-18 15:24:13'
WHERE `id` = 'some_id'

Short and simple:

new DirectoryInfo(path).GetFiles().OrderByDescending(o => o.LastWriteTime).FirstOrDefault();

try

$("#my_txtbox").keypress(function(event) {event.preventDefault();});

Iterate over an objects attributes in python:

class C:
    a = 5
    b = [1,2,3]
    def foobar():
        b = "hi"    

for attr, value in C.__dict__.iteritems():
    print "Attribute: " + str(attr or "")
    print "Value: " + str(value or "")

Prints:

python test.py
Attribute: a
Value: 5
Attribute: foobar
Value: <function foobar at 0x7fe74f8bfc08>
Attribute: __module__
Value: __main__
Attribute: b
Value: [1, 2, 3]
Attribute: __doc__
Value:

Try this (I've used Home controller and Index View):

return RedirectToAction("Index", "Home");

In my app I have app delegate and other classes that need to be accessed by the tests as public. As outlined here, I then import my my app into my tests.

When I recently created two new classes ,their test targets were both the main and testing parts. Removing them from their membership from the tests solved the issue.

Converting the object to JSON, and then parsing it, works for me, like:

JSON.parse(JSON.stringify(object))

This is exceedingly tricky in standard Unix, and most solutions run foul of newlines or some other character. However, if you are using the GNU tool set, then you can exploit the find option -print0 and use xargs with the corresponding option -0 (minus-zero). There are two characters that cannot appear in a simple filename; those are slash and NUL '\0'. Obviously, slash appears in pathnames, so the GNU solution of using a NUL '\0' to mark the end of the name is ingenious and fool-proof.

It's seems the obvious answer was missing. To get all data from a table (Ttable) where the column (DatetimeColumn) is a datetime with a timestamp the following query can be used:

SELECT * FROM Ttable
WHERE DATEDIFF(day,Ttable.DatetimeColumn ,GETDATE()) = 1 -- yesterday

This can easily be changed to today, last month, last year, etc.

Use hashes when you don't want to be able to get back the original input, use encryption when you do.

Hashes take some input and turn it into some bits (usually thought of as a number, like a 32 bit integer, 64 bit integer, etc). The same input will always produce the same hash, but you PRINCIPALLY lose information in the process so you can't reliably reproduce the original input (there are a few caveats to that however).

Encryption principally preserves all of the information you put into the encryption function, just makes it hard (ideally impossible) for anyone to reverse back to the original input without possessing a specific key.

Simple Example of Hashing

Here's a trivial example to help you understand why hashing can't (in the general case) get back the original input. Say I'm creating a 1-bit hash. My hash function takes a bit string as input and sets the hash to 1 if there are an even number of bits set in the input string, else 0 if there were an odd number.

Example:

Input    Hash
0010     0
0011     1
0110     1
1000     0

Note that there are many input values that result in a hash of 0, and many that result in a hash of 1. If you know the hash is 0, you can't know for sure what the original input was.

By the way, this 1-bit hash isn't exactly contrived... have a look at parity bit.

Simple Example of Encryption

You might encrypt text by using a simple letter substitution, say if the input is A, you write B. If the input is B, you write C. All the way to the end of the alphabet, where if the input is Z, you write A again.

Input   Encrypted
CAT     DBU
ZOO     APP

Just like the simple hash example, this type of encryption has been used historically.

File.getParent() from Java Documentation

You should use keyPressed if you want an immediate effect, and keyReleased if you want the effect after you release the key. You cannot use keyTyped because F5 is not a character. keyTyped is activated only when an character is pressed.

You need the following line:

<script src="../jquery/development-bundle/ui/i18n/jquery.ui.datepicker-sv.js"></script>

Adjust the path depending on where you put the jquery-files.

I've just run in a similar issue. git diff file showed nothing because I added file to the Git index with some part of its name in uppercase: GeoJSONContainer.js.

Afterwards, I've renamed it to GeoJsonContainer.js and changes stopped being tracked. git diff GeoJsonContainer.js was showing nothing. I had to remove the file from the index with a force flag, and add the file again:

git rm -f GeoJSONContainer.js
git add GeoJSONContainer.js

If you get the IP address from a DHCP server, you can also set the server to send a DNS server. Or add the nameserver 8.8.8.8 into /etc/resolvconf/resolv.conf.d/base file. The information in this file is included in the resolver configuration file even when no interfaces are configured.

Why not just use a custom format for the cell you need to quote?

If you set a custom format to the cell column, all values will take on that format.

For numbers....like a zip code....it would be this '#' For string text, it would be this '@'

You save the file as csv format, and it will have all the quotes wrapped around the cell data as needed.

How to get rid of a header(first row) and an index(first column).

To write to CSV file:

df = pandas.DataFrame(your_array)
df.to_csv('your_array.csv', header=False, index=False)

To read from CSV file:

df = pandas.read_csv('your_array.csv')
a = df.values

If you want to read a CSV file that doesn't contain a header, pass additional parameter header:

df = pandas.read_csv('your_array.csv', header=None)

Twitter now has a sass-ready version of bootstrap with gem included, so it is easier than ever to add it to Rails.

Simply add to your gemfile the following:

gem 'sass-rails', '>= 3.2' # sass-rails needs to be higher than 3.2
gem 'bootstrap-sass', '~> 3.1.1'

bundle install and restart your server to make the files available through the pipeline.

There is also support for compass and sass-only: https://github.com/twbs/bootstrap-sass

Your question shows you have succumbed to some of the common misconceptions surrounding table variables and temporary tables.

I have written quite an extensive answer on the DBA site looking at the differences between the two object types. This also addresses your question about disk vs memory (I didn't see any significant difference in behaviour between the two).

Regarding the question in the title though as to when to use a table variable vs a local temporary table you don't always have a choice. In functions, for example, it is only possible to use a table variable and if you need to write to the table in a child scope then only a #temp table will do (table-valued parameters allow readonly access).

Where you do have a choice some suggestions are below (though the most reliable method is to simply test both with your specific workload).

1. If you need an index that cannot be created on a table variable then you will of course need a #temporary table. The details of this are version dependant however. For SQL Server 2012 and below the only indexes that could be created on table variables were those implicitly created through a UNIQUE or PRIMARY KEY constraint. SQL Server 2014 introduced inline index syntax for a subset of the options available in CREATE INDEX. This has been extended since to allow filtered index conditions. Indexes with INCLUDE-d columns or columnstore indexes are still not possible to create on table variables however.

2. If you will be repeatedly adding and deleting large numbers of rows from the table then use a #temporary table. That supports TRUNCATE (which is more efficient than DELETE for large tables) and additionally subsequent inserts following a TRUNCATE can have better performance than those following a DELETE as illustrated here.

3. If you will be deleting or updating a large number of rows then the temp table may well perform much better than a table variable - if it is able to use rowset sharing (see "Effects of rowset sharing" below for an example).
4. If the optimal plan using the table will vary dependent on data then use a #temporary table. That supports creation of statistics which allows the plan to be dynamically recompiled according to the data (though for cached temporary tables in stored procedures the recompilation behaviour needs to be understood separately).
5. If the optimal plan for the query using the table is unlikely to ever change then you may consider a table variable to skip the overhead of statistics creation and recompiles (would possibly require hints to fix the plan you want).
6. If the source for the data inserted to the table is from a potentially expensive SELECT statement then consider that using a table variable will block the possibility of this using a parallel plan.
7. If you need the data in the table to survive a rollback of an outer user transaction then use a table variable. A possible use case for this might be logging the progress of different steps in a long SQL batch.
8. When using a #temp table within a user transaction locks can be held longer than for table variables (potentially until the end of transaction vs end of statement dependent on the type of lock and isolation level) and also it can prevent truncation of the tempdb transaction log until the user transaction ends. So this might favour the use of table variables.
9. Within stored routines, both table variables and temporary tables can be cached. The metadata maintenance for cached table variables is less than that for #temporary tables. Bob Ward points out in his tempdb presentation that this can cause additional contention on system tables under conditions of high concurrency. Additionally, when dealing with small quantities of data this can make a measurable difference to performance.

Effects of rowset sharing

DECLARE @T TABLE(id INT PRIMARY KEY, Flag BIT);

CREATE TABLE #T (id INT PRIMARY KEY, Flag BIT);

INSERT INTO @T 
output inserted.* into #T
SELECT TOP 1000000 ROW_NUMBER() OVER (ORDER BY @@SPID), 0
FROM master..spt_values v1, master..spt_values v2

SET STATISTICS TIME ON

/*CPU time = 7016 ms,  elapsed time = 7860 ms.*/
UPDATE @T SET Flag=1;

/*CPU time = 6234 ms,  elapsed time = 7236 ms.*/
DELETE FROM @T

/* CPU time = 828 ms,  elapsed time = 1120 ms.*/
UPDATE #T SET Flag=1;

/*CPU time = 672 ms,  elapsed time = 980 ms.*/
DELETE FROM #T

DROP TABLE #T

kk: (01-24) will look like 01, 02..24.

HH:(00-23) will look like 00, 01..23.

hh:(01-12 in AM/PM) will look like 01, 02..12.

so the last printout (working2) is a bit weird. It should say 12:00:00 (edit: if you were setting the working2 timezone and format, which (as kdagli pointed out) you are not)

Update on 16-Feb-2019

The approach mentioned earlier below is essentially "Resource Owner Password Credential" grant type of OAuth2.0. This is an easy way to get up and running. However, with this approach every application in the organization will end up with its own authentication and authorization mechanisms. The recommended approach is "Authorization Code" grant type. Additionally, in my earlier answer below I recommended browser localStorage for storing auth tokens. However, I've come to believe that cookie is the right option for this purpose. I have detailed my reasons, authorization code grant type implementation approach, security considerations etc. in this StackOverflow answer.

I think the following approach can be used for REST service authentication:

1. Create a login RESTful API to accept username and password for authentication. Use HTTP POST method to prevent caching and SSL for security during transit On successful authentication, the API returns two JWTs - one access token (shorter validity, say 30 minutes) and one refresh token (longer validity, say 24 hours)
2. The client (a web based UI) stores the JWTs in local storage and in every subsequent API call passes the access token in "Authorization: Bearer #access token" header
3. The API checks the validity of the token by verifying the signature and expiry date. If the token is valid, check if the user (It interprets the "sub" claim in JWT as username) has access to the API with a cache lookup. If the user is authorized to access the API, execute the business logic
4. If the token is expired, the API returns HTTP response code 400
5. The client, on receiving 400/401, invokes another REST API with the refresh token in "Authorization: Bearer #refresh token" header to get a new access token.
6. On receiving the call with refresh token, check if the refresh token is valid by checking the signature and the expiry date. If the refresh token is valid, refresh the access right cache of the user from DB and return new access token and refresh token. If the refresh token is invalid, return HTTP response code 400
7. If a new access token and refresh token are returned, go to step 2. If HTTP response code 400 is returned, the client assumes that the refresh token has expired and asks for username and password from the user
8. For logout, purge the local storage

With this approach we are doing the expensive operation of loading the cache with user specific access right details every 30 minutes. So if an access is revoked or new access is granted, it takes 30 minutes to reflect or a logout followed by a login.

if its mysql, you can try something like this.

select 
   (select count(*) from TABLENAME WHERE a = 'null') as total_null, 
   (select count(*) from TABLENAME WHERE a != 'null') as total_not_null
FROM TABLENAME

One use case is to make an ajax call before the user closes the window or leaves the page. This would be like deleting some temporary records in the database before the user can navigate to another site or closes the browser.

 $(window).unload(
        function(){
            $.ajax({
            url: 'your url',
            global: false,
            type: 'POST',
            data: {},
            async: false, //blocks window close
            success: function() {}
        });
    });

Use redirect and url_for

from flask import redirect, url_for

@app.route('/', methods=['GET'])
def metrics():
    return redirect(url_for('static', filename='jenkins_analytics.html'))

This servers all files (css & js...) referenced in your html.

On Error Resume Next means that On Error, It will resume to the next line to resume.

e.g. if you try the Try block, That will stop the script if a error occurred

The only way I know is this:

Reassure that preferences | Basic Notes Client configuration | Drag and drop saves as eml file is checked

1) Drag your email to e.g. your desktop or to an explorer instance (will be saved as an eml file).
2) Attach this file to your opened email by either selecting it with the paperclip menu item or drag 'n drop the file into the opened email.

There may be multiple ways to count the tables of a database. My favorite is this on:

SELECT
    COUNT(*)
FROM
    `information_schema`.`tables`
WHERE
    `table_schema` = 'my_database_name'
;

You can use either of these functions:

// This should work in node.js and other ES5 compliant implementations.
function isEmptyObject(obj) {
  return !Object.keys(obj).length;
}

// This should work both there and elsewhere.
function isEmptyObject(obj) {
  for (var key in obj) {
    if (Object.prototype.hasOwnProperty.call(obj, key)) {
      return false;
    }
  }
  return true;
}

Example usage:

if (isEmptyObject(query)) {
  // There are no queries.
} else {
  // There is at least one query,
  // or at least the query object is not empty.
}

Try AhtiK Eclipse WordWrap, it works for me: http://www.ahtik.com/eclipse-update/

Recursion is better than iteration for problems that can be broken down into multiple, smaller pieces.

For example, to make a recursive Fibonnaci algorithm, you break down fib(n) into fib(n-1) and fib(n-2) and compute both parts. Iteration only allows you to repeat a single function over and over again.

However, Fibonacci is actually a broken example and I think iteration is actually more efficient. Notice that fib(n) = fib(n-1) + fib(n-2) and fib(n-1) = fib(n-2) + fib(n-3). fib(n-1) gets calculated twice!

A better example is a recursive algorithm for a tree. The problem of analyzing the parent node can be broken down into multiple smaller problems of analyzing each child node. Unlike the Fibonacci example, the smaller problems are independent of each other.

So yeah - recursion is better than iteration for problems that can be broken down into multiple, smaller, independent, similar problems.

As you want to specifically search for a wildcard character you need to escape that

This is done by adding the ESCAPE clause to your LIKE expression. The character that is specified with the ESCAPE clause will "invalidate" the following wildcard character.

You can use any character you like (just not a wildcard character). Most people use a \ because that is what many programming languages also use

So your query would result in:

select * 
from Manager
where managerid LIKE '\_%' escape '\'
and managername like '%\_%' escape '\';

But you can just as well use any other character:

select * 
from Manager
where managerid LIKE '#_%' escape '#'
and managername like '%#_%' escape '#';

Here is an SQLFiddle example: http://sqlfiddle.com/#!6/63e88/4

This could also occur if you refer to a variable in the data.frame that doesn't exist. For example, recently I forgot to tell ddply to summarize by one of my variables that I used in geom_line to specify line color. Then, ggplot didn't know where to find the variable I hadn't created in the summary table, and I got this error.

If you don't want to go with separate struct definition for nested struct and you don't like second method suggested by @OneOfOne you can use this third method:

package main
import "fmt"
type Configuration struct {
    Val   string
    Proxy struct {
        Address string
        Port    string
    }
}

func main() {
    c := &Configuration{
        Val: "test",
    }

    c.Proxy.Address = `127.0.0.1`
    c.Proxy.Port = `8080`
}

You can check it here: https://play.golang.org/p/WoSYCxzCF2

Your sample code won't work as shown because you forgot to include a Console.ReadLine() before the serviceHost.Close() line. That means the host is opened and then immediately closed.

Other than that, it seems you have a permission problem on your machine. Ensure you are logged-in as an administrator account on your machine. If you are an administrator then it may be that you don't have the World Wide Web Publishing Service (W3SVC) running to handle HTTP requests.

If your two angles are x and y, then one of the angles between them is abs(x - y). The other angle is (2 * PI) - abs(x - y). So the value of the smallest of the 2 angles is:

min((2 * PI) - abs(x - y), abs(x - y))

This gives you the absolute value of the angle, and it assumes the inputs are normalized (ie: within the range [0, 2p)).

If you want to preserve the sign (ie: direction) of the angle and also accept angles outside the range [0, 2p) you can generalize the above. Here's Python code for the generalized version:

PI = math.pi
TAU = 2*PI
def smallestSignedAngleBetween(x, y):
    a = (x - y) % TAU
    b = (y - x) % TAU
    return -a if a < b else b

Note that the % operator does not behave the same in all languages, particularly when negative values are involved, so if porting some sign adjustments may be necessary.

One potential gotcha that has bitten me before:

I like to have at most one @Before method in each test class, because order of running the @Before methods defined within a class is not guaranteed. Typically, I will call such a method setUpTest().

But, although @Before is documented as The @Before methods of superclasses will be run before those of the current class. No other ordering is defined., this only applies if each method marked with @Before has a unique name in the class hierarchy.

For example, I had the following:

public class AbstractFooTest {
  @Before
  public void setUpTest() { 
     ... 
  }
}

public void FooTest extends AbstractFooTest {
  @Before
  public void setUpTest() { 
    ...
  }
}

I expected AbstractFooTest.setUpTest() to run before FooTest.setUpTest(), but only FooTest.setupTest() was executed. AbstractFooTest.setUpTest() was not called at all.

The code must be modified as follows to work:

public void FooTest extends AbstractFooTest {
  @Before
  public void setUpTest() {
    super.setUpTest();
    ...
  }
}

Check if your object is a list or a vector. To do this, type is.list(yourobject). If this is true, try renaming it x<-unlist(yourobject). This will make it into a vector you can plot.

You can just run

git config --global credential.helper wincred

after installing and logging into GIT for windows in your system.

There are codes for other space characters, and the codes as such work well, but the characters themselves are legacy character. They have been included into character sets only due to their presence in existing character data, rather than for use in new documents. For some combinations of font and browser version, they may cause a generic glyph of unrepresentable character to be shown. For details, check my page about Unicode spaces.

So using CSS is safer and lets you specify any desired amount of spacing, not just the specific widths of fixed-width spaces. If you just want to have added spacing around your h2 elements, as it seems to me, then setting padding on those elements (changing the value of the padding: 0 settings that you already have) should work fine.

Better solution is to add a new property "Fonts provided by application" to your info.plist file.

Then, you can use your custom font like normal UIFont.

The following will do.

string datestring = DateTime.Now.ToString("yyyy-MM-dd", CultureInfo.InvariantCulture);

$(function () {
    $('#datepicker').datepicker({
        dateFormat: 'yy-mm-dd',
        showButtonPanel: true,
        changeMonth: true,
        changeYear: true,
yearRange: '1999:2012',
        showOn: "button",
        buttonImage: "images/calendar.gif",
        buttonImageOnly: true,
        minDate: new Date(1999, 10 - 1, 25),
        maxDate: '+30Y',
        inline: true
    });
});

Just added year range option. It should solve the problem

#id {
  position: relative;
  opacity: 0.99;
}

#id::before {
  content: "";
  position: absolute;
  width: 100%;
  height: 100%;
  z-index: -1;
  background: url('image.png');
  opacity: 0.3;
}

Hack with opacity 0.99 (less than 1) creates z-index context so you can not worry about global z-index values. (Try to remove it and see what happens in the next demo where parent wrapper has positive z-index.)
If your element already has z-index, then you don't need this hack.

Demo.

Try this formula (it will return value from A1 as is if it's not a date):

=TEXT(A1,"mm-yyyy")

Or this formula (it's more strict, it will return #VALUE error if A1 is not date):

=TEXT(MONTH(A1),"00")&"-"&YEAR(A1)

You could use a labeled BREAK statement:

search:
    for (i = 0; i < arrayOfInts.length; i++) {
        for (j = 0; j < arrayOfInts[i].length; j++) {
            if (arrayOfInts[i][j] == searchfor) {
                foundIt = true;
                break search;
            }
        }
    }

However, in properly designed code, you shouldn't need GOTO functionality.

You can use IN operator as below

select * from dbo.books where isbn IN
(select isbn from dbo.lending where lended_date between @fdate and @tdate)

It sounds like your table has no key. You should be able to simply try the INSERT: if it’s a duplicate then the key constraint will bite and the INSERT will fail. No worries: you just need to ensure the application doesn't see/ignores the error. When you say 'primary key' you presumably mean IDENTITY value. That's all very well but you also need a key constraint (e.g. UNIQUE) on your natural key.

Also, I wonder whether your procedure is doing too much. Consider having separate procedures for 'create' and 'read' actions respectively.

If you have dynamic element ID where you need to assign the dynamic value, you may use this:

//element_id = you dynamic id.
//dynamic_val = you dynamic value.
let _el = document.getElementById(element_id);
_el.value = dynamic_val.toString();

This works for me.

Either set the enum name to be the same as the string you want or, more generally,you can associate arbitrary attributes with your enum values:

enum Strings {
   STRING_ONE("ONE"), STRING_TWO("TWO");
   private final String stringValue;
   Strings(final String s) { stringValue = s; }
   public String toString() { return stringValue; }
   // further methods, attributes, etc.
}

It's important to have the constants at the top, and the methods/attributes at the bottom.

Making these 2 communicate

=IF(OR(AND(MID(K27,6,1)="N",(MID(K27,6,1)="C"),(MID(K27,6,1)="H"),(MID(K27,6,1)="I"),(MID(K27,6,1)="B"),(MID(K27,6,1)="F"),(MID(K27,6,1)="L"),(MID(K27,6,1)="M"),(MID(K27,6,1)="P"),(MID(K27,6,1)="R"),(MID(K27,6,1)="P"),ISTEXT(G27)="61"),AND(RIGHT(K27,2)=G27)),"Good","Review")

=IF(AND(RIGHT(K27,2)=G27),"Good","Review")

According to the manual this should work:

Custom key/value method:

You can include an operator in the first parameter in order to control the comparison:

$this->db->where('name !=', $name);
$this->db->where('id <', $id);
Produces: WHERE name != 'Joe' AND id < 45

Search for $this->db->where(); and look at item #2.

To get all tables with columns columnA or ColumnB in the database YourDatabase:

SELECT DISTINCT TABLE_NAME 
    FROM INFORMATION_SCHEMA.COLUMNS
    WHERE COLUMN_NAME IN ('columnA','ColumnB')
        AND TABLE_SCHEMA='YourDatabase';

This should not affect everyone, but one of the semi-hidden reasons of the repository size being large could be Git submodules.

You might have added one or more submodules, but stopped using it at some time, and some files remained in .git/modules directory. To make redundant submodule files gone away, see this question.

However, just like the main repository, the other way is to navigate to the submodule directory in .git/modules, and do a, for example, git gc --aggressive --prune.

These should have a good impact in the repository size, but as long as you use Git submodules, e.g. especially with large libraries, your repository size should not change drastically.

Here's my shell script solution, which deletes derived data and cleans a project's cached assets, for Xcode 4, 5 and 6.

Sometimes, simply calling rm -rf on the Derived Data directory leaves a lingering file or two, but my script loops until all files are deleted.

Your code seems fine except the result is an NSArray, not an NSDictionary, here is an example:

The first two lines just creates a data object with the JSON, the same as you would get reading it from the net.

NSString *jsonString = @"[{\"id\": \"1\", \"name\":\"Aaa\"}, {\"id\": \"2\", \"name\":\"Bbb\"}]";
NSData *jsonData = [jsonString dataUsingEncoding:NSUTF8StringEncoding];

NSError *e;
NSMutableArray *jsonList = [NSJSONSerialization JSONObjectWithData:jsonData options:NSJSONReadingMutableContainers error:&e];
NSLog(@"jsonList: %@", jsonList);

NSLog contents (a list of dictionaries):

jsonList: (
           {
               id = 1;
               name = Aaa;
           },
           {
               id = 2;
               name = Bbb;
           }
           )

I was struggling with this exact issue for three days. I had set permissions on the script to 755. I had been calling my script as follows.

<?php
   $outcome = shell_exec('/tmp/clearUp.sh');
   echo $outcome;
?>

My script was as follows.

#!bin/bash
find . -maxdepth 1 -name "search*.csv" -mmin +0 -exec rm {} \;

I was getting no output or feedback. The change I made to get the script to run was to add a cd to tmp inside the script:

#!bin/bash
cd /tmp;
find . -maxdepth 1 -name "search*.csv" -mmin +0 -exec rm {} \;

This was more by luck than judgement but it is now working perfectly. I hope this helps.

It ought to be implemented in msysgit, but there are two downsides:

• Symbolic links are only available in Windows Vista and later (should not be an issue in 2011, and yet it is...), since older versions only support directory junctions.
• (the big one) Microsoft considers symbolic links a security risk and so only administrators can create them by default. You'll need to elevate privileges of the git process or use fstool to change this behavior on every machine you work on.

I did a quick search and there is work being actively done on this, see issue 224.

The apache benchmark tool is very basic, and while it will give you a solid idea of some performance, it is a bad idea to only depend on it if you plan to have your site exposed to serious stress in production.

Having said that, here's the most common and simplest parameters:

-c: ("Concurrency"). Indicates how many clients (people/users) will be hitting the site at the same time. While ab runs, there will be -c clients hitting the site. This is what actually decides the amount of stress your site will suffer during the benchmark.

-n: Indicates how many requests are going to be made. This just decides the length of the benchmark. A high -n value with a -c value that your server can support is a good idea to ensure that things don't break under sustained stress: it's not the same to support stress for 5 seconds than for 5 hours.

-k: This does the "KeepAlive" funcionality browsers do by nature. You don't need to pass a value for -k as it it "boolean" (meaning: it indicates that you desire for your test to use the Keep Alive header from HTTP and sustain the connection). Since browsers do this and you're likely to want to simulate the stress and flow that your site will have from browsers, it is recommended you do a benchmark with this.

The final argument is simply the host. By default it will hit http:// protocol if you don't specify it.

ab -k -c 350 -n 20000 example.com/

By issuing the command above, you will be hitting http://example.com/ with 350 simultaneous connections until 20 thousand requests are met. It will be done using the keep alive header.

After the process finishes the 20 thousand requests, you will receive feedback on stats. This will tell you how well the site performed under the stress you put it when using the parameters above.

For finding out how many people the site can handle at the same time, just see if the response times (means, min and max response times, failed requests, etc) are numbers your site can accept (different sites might desire different speeds). You can run the tool with different -c values until you hit the spot where you say "If I increase it, it starts to get failed requests and it breaks".

Depending on your website, you will expect an average number of requests per minute. This varies so much, you won't be able to simulate this with ab. However, think about it this way: If your average user will be hitting 5 requests per minute and the average response time that you find valid is 2 seconds, that means that 10 seconds out of a minute 1 user will be on requests, meaning only 1/6 of the time it will be hitting the site. This also means that if you have 6 users hitting the site with ab simultaneously, you are likely to have 36 users in simulation, even though your concurrency level (-c) is only 6.

This depends on the behavior you expect from your users using the site, but you can get it from "I expect my user to hit X requests per minute and I consider an average response time valid if it is 2 seconds". Then just modify your -c level until you are hitting 2 seconds of average response time (but make sure the max response time and stddev is still valid) and see how big you can make -c.

I hope I explained this clear :) Good luck

One solution you could use is to assign a more generalized class to any div you want the click event handler bound to.

For example:

HTML:

<body>
<div id="dog" class="selected" data-selected="false">dog</div>
<div id="cat" class="selected" data-selected="true">cat</div>
<div id="mouse" class="selected" data-selected="false">mouse</div>

<div class="dog"><img/></div>
<div class="cat"><img/></div>
<div class="mouse"><img/></div>
</body>

JS:

$( ".selected" ).each(function(index) {
    $(this).on("click", function(){
        // For the boolean value
        var boolKey = $(this).data('selected');
        // For the mammal value
        var mammalKey = $(this).attr('id'); 
    });
});

First of all, you should install SignalR.Host.Self on the server application and SignalR.Client on your client application by nuget :

PM> Install-Package SignalR.Hosting.Self -Version 0.5.2

PM> Install-Package Microsoft.AspNet.SignalR.Client

Then add the following code to your projects ;)

(run the projects as administrator)

Server console app:

using System;
using SignalR.Hubs;

namespace SignalR.Hosting.Self.Samples {
    class Program {
        static void Main(string[] args) {
            string url = "http://127.0.0.1:8088/";
            var server = new Server(url);

            // Map the default hub url (/signalr)
            server.MapHubs();

            // Start the server
            server.Start();

            Console.WriteLine("Server running on {0}", url);

            // Keep going until somebody hits 'x'
            while (true) {
                ConsoleKeyInfo ki = Console.ReadKey(true);
                if (ki.Key == ConsoleKey.X) {
                    break;
                }
            }
        }

        [HubName("CustomHub")]
        public class MyHub : Hub {
            public string Send(string message) {
                return message;
            }

            public void DoSomething(string param) {
                Clients.addMessage(param);
            }
        }
    }
}

Client console app:

using System;
using SignalR.Client.Hubs;

namespace SignalRConsoleApp {
    internal class Program {
        private static void Main(string[] args) {
            //Set connection
            var connection = new HubConnection("http://127.0.0.1:8088/");
            //Make proxy to hub based on hub name on server
            var myHub = connection.CreateHubProxy("CustomHub");
            //Start connection

            connection.Start().ContinueWith(task => {
                if (task.IsFaulted) {
                    Console.WriteLine("There was an error opening the connection:{0}",
                                      task.Exception.GetBaseException());
                } else {
                    Console.WriteLine("Connected");
                }

            }).Wait();

            myHub.Invoke<string>("Send", "HELLO World ").ContinueWith(task => {
                if (task.IsFaulted) {
                    Console.WriteLine("There was an error calling send: {0}",
                                      task.Exception.GetBaseException());
                } else {
                    Console.WriteLine(task.Result);
                }
            });

            myHub.On<string>("addMessage", param => {
                Console.WriteLine(param);
            });

            myHub.Invoke<string>("DoSomething", "I'm doing something!!!").Wait();


            Console.Read();
            connection.Stop();
        }
    }
}

x^y is not "x to the power of y". It's "x XOR y".

@inmyth's answer is correct, just modify the code a bit, to handle empty list.

public class NewsAdapter extends RecyclerView.Adapter<...> {    
    ...
    private static List mFeedsList;
    ...    
    public void swap(List list){
            if (mFeedsList != null) {
                mFeedsList.clear();
                mFeedsList.addAll(list);
            }
            else {
                mFeedsList = list;
            }
            notifyDataSetChanged();
    }

I am using Retrofit to fetch the list, on Retrofit's onResponse() use,

adapter.swap(feedList);

If you are using mac, try giving root access to gradlew by doing

chmod +x ./gradlew

Always prefer to use the language features over some additional tools like preprocessor.

ES.31: Don't use macros for constants or "functions"

Macros are a major source of bugs. Macros don't obey the usual scope and type rules. Macros don't obey the usual rules for argument passing. Macros ensure that the human reader sees something different from what the compiler sees. Macros complicate tool building.

From C++ Core Guidelines

Consider:

Function GetFolder() As String
    Dim fldr As FileDialog
    Dim sItem As String
    Set fldr = Application.FileDialog(msoFileDialogFolderPicker)
    With fldr
        .Title = "Select a Folder"
        .AllowMultiSelect = False
        .InitialFileName = Application.DefaultFilePath
        If .Show <> -1 Then GoTo NextCode
        sItem = .SelectedItems(1)
    End With
NextCode:
    GetFolder = sItem
    Set fldr = Nothing
End Function

This code was adapted from Ozgrid

and as jkf points out, from Mr Excel

A bit late here, but I could use SNag's solution further into $.ajax(). Here is the code if it would help anyone:

var array = [1, 2, 3, 4, 5];

$.ajax({
    type: "GET",
    url: '/controller/MyAction',
    data: $.param({ data: array}, true),
    contentType: 'application/json; charset=utf-8',
    success: function (data) {
    },
    error: function (x, y, z) {
    }
});

// Action Method
public void MyAction(List<int> data)
{
    // do stuff here
}

You use a for..in loop for this. Be sure to check if the object owns the properties or all inherited properties are shown as well. An example is like this:

var obj = {a: 1, b: 2};
for (var key in obj) {
  if (obj.hasOwnProperty(key)) {
    var val = obj[key];
    console.log(val);
  }
}

Or if you need recursion to walk through all the properties:

var obj = {a: 1, b: 2, c: {a: 1, b: 2}};
function walk(obj) {
  for (var key in obj) {
    if (obj.hasOwnProperty(key)) {
      var val = obj[key];
      console.log(val);
      walk(val);
    }
  }
}
walk(obj);

This code bellow will make your whole table clickable. Clicking the links in this example will show the link in an alert dialog instead of following the link.

The HTML:

Here's the HTML behind the above example:

    <table id="example">
    <tr>
     <th>&nbsp;</th>
     <th>Name</th>
     <th>Description</th>
     <th>Price</th>
   </tr>
   <tr>
     <td><a href="apples">Edit</a></td>
     <td>Apples</td>
     <td>Blah blah blah blah</td>
     <td>10.23</td>
   </tr>
    <tr>
     <td><a href="bananas">Edit</a></td>
     <td>Bananas</td>
     <td>Blah blah blah blah</td>
     <td>11.45</td>
   </tr>
   <tr>
     <td><a href="oranges">Edit</a></td>
     <td>Oranges</td>
     <td>Blah blah blah blah</td>
     <td>12.56</td>
   </tr>

And the CSS:

    table#example {
    border-collapse: collapse;   
}
#example tr {
    background-color: #eee;
    border-top: 1px solid #fff;
}
#example tr:hover {
    background-color: #ccc;
}
#example th {
    background-color: #fff;
}
#example th, #example td {
    padding: 3px 5px;
}
#example td:hover {
    cursor: pointer;
}

The jQuery

And finally the jQuery which makes the magic happen:

    $(document).ready(function() {

    $('#example tr').click(function() {
        var href = $(this).find("a").attr("href");
        if(href) {
            window.location = href;
        }
    });

});

What it does is when a row is clicked, a search is done for the href belonging to an anchor. If one is found, the window's location is set to that href.

if you use Bootstrap 2.2.1 then maybe is this what you are looking for.

Union has not good performance : this article describe about compare them with together

var dict = list2.ToDictionary(p => p.Number);
foreach (var person in list1)
{
        dict[person.Number] = person;
}
var merged = dict.Values.ToList();

Lists and LINQ merge: 4820ms
Dictionary merge: 16ms
HashSet and IEqualityComparer: 20ms
LINQ Union and IEqualityComparer: 24ms

Let's see this in action:

var b = true;_x000D_
_x000D_
console.log(b); // true_x000D_
_x000D_
b = !b;_x000D_
console.log(b); // false_x000D_
_x000D_
b = !b;_x000D_
console.log(b); // true

Anyways, there is no shorter way than what you currently have.

In my case, I set UTC as a time zone for everything: the system, the database server, etc. every time that I can. If my customer requires another time zone, then I configure it on the app.

I almost always prefer timestamps rather than datetime fields, because timestamps include the timezone implicitly. So, since the moment that the app will be accessed from users from different time zones and you want them to see dates and times in their local timezone, this field type makes it pretty easy to do it than if the data were saved in datetime fields.

As a plus, in the case of a migration of the database to a system with another timezone, I would feel more confident using timestamps. Not to say possible issues when calculating differences between two moments with a sumer time change in between and needing a precision of 1 hour or less.

So, to summarize, I value this advantages of timestamp:

• ready to use on international (multi time zone) apps
• easy migrations between time zones
• pretty easy to calculate diferences (just subtract both timestamps)
• no worry about dates in/out a summer time period

For all this reasons, I choose UTC & timestamp fields where posible. And I avoid headaches ;)

My problem was very similar (produces same problem). After refactoring variable name by "refactor -> rename" option in Android Studio (from "value" to "myValue") i found changes in manifest file, too. Meta-data "value" pool has changed to "myValue".

<meta-data
        android:name="com.facebook.sdk.ApplicationId"
        android:myValue="@string/facebook_app_id"/>

After revert file everything seams to be ok again.

<meta-data
        android:name="com.facebook.sdk.ApplicationId"
        android:value="@string/facebook_app_id"/>

I hope, it will help someone!

./me casts raise_dead()

I was looking for something like this, but I also needed to reuse the same string minus two parameters so I ended up with something like:

my_exe ()
{
    mysql -sN -e "select $1 from heat.stack where heat.stack.name=\"$2\";"
}

This is something I use to monitor openstack heat stack creation. In this case I expect two conditions, an action 'CREATE' and a status 'COMPLETE' on a stack named "Somestack"

To get those variables I can do something like:

ACTION=$(my_exe action Somestack)
STATUS=$(my_exe status Somestack)
if [[ "$ACTION" == "CREATE" ]] && [[ "$STATUS" == "COMPLETE" ]]
...

press WIN+R and from the run dialog run dialog Execute the following: **%appdata%..\Local\Android**

You should now be presented with Folder Explorer displaying the parent directory of the SDK.

If you are setting the contents of IFrame using javascript document.write() then you must close the document by newWin.document.close(); otherwise the following code will not work and print will print the contents of whole page instead of only the IFrame contents.

var frm = document.getElementById(id).contentWindow;
frm.focus();// focus on contentWindow is needed on some ie versions
frm.print();

Log.WriteLine("Value of CompanyName column:" + thisReader["CompanyName"]); 

It is important that you include the "required" keyword inside each one of your mandatory input tags for it to work.

 <form (ngSubmit)="login(loginForm.value)" #loginForm="ngForm">
    ...
    <input ngModel required name="username" id="userName" type="text" class="form-control" placeholder="User Name..." />
    <button type="submit" [disabled]="loginForm.invalid" class="btn btn-primary">Login</button>

You're not assigning any id to the text view, but you're using tv.getId() to pass it to the addRule method as a parameter. Try to set a unique id via tv.setId(int).

You could also use the LinearLayout with vertical orientation, that might be easier actually. I prefer LinearLayout over RelativeLayouts if not necessary otherwise.

As Draemon says, the closest that Java comes to inline arrays is new String[]{"blah", "hey", "yo"} however there is a neat trick that allows you to do something like

array("blah", "hey", "yo") with the type automatically inferred.

I have been working on a useful API for augmenting the Java language to allow for inline arrays and collection types. For more details google project Espresso4J or check it out here

I got that error, when sometimes I type in Chinese language. When it comes to punctuation marks, you do not notice that you are actually typing the Chinese version, instead of the English version.

The interpreter will give you an error message, but for human eyes, it is hard to notice the difference.

For example, "," in Chinese; and "," in English. So be careful with your language setting.
