Programs & Examples On #Control characters

As a supplement,

1, Carriage return: It's a printer terminology meaning changing the print location to the beginning of current line. In computer world, it means return to the beginning of current line in most cases but stands for new line rarely.

2, Line feed: It's a printer terminology meaning advancing the paper one line. So Carriage return and Line feed are used together to start to print at the beginning of a new line. In computer world, it generally has the same meaning as newline.

3, Form feed: It's a printer terminology, I like the explanation in this thread.

If you were programming for a 1980s-style printer, it would eject the paper and start a new page. You are virtually certain to never need it.

http://en.wikipedia.org/wiki/Form_feed

It's almost obsolete and you can refer to Escape sequence \f - form feed - what exactly is it? for detailed explanation.

Note, we can use CR or LF or CRLF to stand for newline in some platforms but newline can't be stood by them in some other platforms. Refer to wiki Newline for details.

LF: Multics, Unix and Unix-like systems (Linux, OS X, FreeBSD, AIX, Xenix, etc.), BeOS, Amiga, RISC OS, and others

CR: Commodore 8-bit machines, Acorn BBC, ZX Spectrum, TRS-80, Apple II family, Oberon, the classic Mac OS up to version 9, MIT Lisp Machine and OS-9

RS: QNX pre-POSIX implementation

0x9B: Atari 8-bit machines using ATASCII variant of ASCII (155 in decimal)

CR+LF: Microsoft Windows, DOS (MS-DOS, PC DOS, etc.), DEC TOPS-10, RT-11, CP/M, MP/M, Atari TOS, OS/2, Symbian OS, Palm OS, Amstrad CPC, and most other early non-Unix and non-IBM OSes

LF+CR: Acorn BBC and RISC OS spooled text output.

Combining CodeIgniter and JavaScript:

//for using the base_url() function
$this->load->helper('url');

echo "<script type='javascript/text'>";
echo "alert('There are no fields to generate a report');"
echo "window.location.href = '" . base_url() . "admin/ahm/panel';"
echo "</script>";

Note: The redirect() function automatically includes the base_url path that is why it wasn't required there.

Based on quentinadam's answer

Swift 5.1

// size refers to the width/height of your tile images, by default is 256.0
// Seems to get better results using round()
// frame.width is the width of the MKMapView

let zoom = round(log2(360 * Double(frame.width) / size / region.span.longitudeDelta))

you can use @see to do that:

sample:

interface View {
        /**
         * @return true: have read contact and call log permissions, else otherwise
         * @see #requestReadContactAndCallLogPermissions()
         */
        boolean haveReadContactAndCallLogPermissions();

        /**
         * if not have permissions, request to user for allow
         * @see #haveReadContactAndCallLogPermissions()
         */
        void requestReadContactAndCallLogPermissions();
    }

In case you do not know the usernames as created here. You can get the users as described by @FallenAngel above.

python manage.py shell 
from django.contrib.auth.models import User
usrs = User.objects.filter(is_superuser=True)
#identify the user
your_user = usrs.filter(username="yourusername")[0]
#youruser = usrs.get(username="yourusername")
#then set the password

However in the event that you created your independent user model. A simple case is when you want to use email as a username instead of the default user name. In which case your user model lives somewhere such as your_accounts_app.models then the above solution wont work. In this case you can instead use the get_user_model method

from django.contrib.auth import get_user_model 
super_users = get_user_model().objects.filter(is_superuser=True)
#proceed to get identify your user
# and set their user password

To get the raw data, use request.data. This only works if it couldn't be parsed as form data, otherwise it will be empty and request.form will have the parsed data.

from flask import request
request.data

There are two following important features that prevent to inherit Abstract class

1. Abstract class must have an abstract method otherwise it is not a abstract class

2. Abstract class must be inherited by derived class,So if a class inherited by other class than what is use of to create object of that class

Here is the code, and you can decide which
(synchronized)StringBuffer or faster StringBuilder to use.

Benchmark shows StringBuilder is Faster.

public class Main {
            int times = 777;
            long t;

            {
                StringBuffer sb = new StringBuffer();
                t = System.currentTimeMillis();
                for (int i = times; i --> 0 ;) {
                    sb.append("");
                    getJSONFromStringBuffer(String stringJSON);
                }
                System.out.println(System.currentTimeMillis() - t);
            }

            {
                StringBuilder sb = new StringBuilder();
                t = System.currentTimeMillis();
                for (int i = times; i --> 0 ;) {
                     getJSONFromStringBUilder(String stringJSON);
                    sb.append("");
                }
                System.out.println(System.currentTimeMillis() - t);
            }
            private String getJSONFromStringBUilder(String stringJSONArray) throws JSONException {
                return new StringBuffer(
                       new JSONArray(stringJSONArray).getJSONObject(0).getString("phonetype"))
                           .append(" ")
                           .append(
                       new JSONArray(employeeID).getJSONObject(0).getString("cat"))
                      .toString();
            }
            private String getJSONFromStringBuffer(String stringJSONArray) throws JSONException {
                return new StringBuffer(
                       new JSONArray(stringJSONArray).getJSONObject(0).getString("phonetype"))
                           .append(" ")
                           .append(
                       new JSONArray(employeeID).getJSONObject(0).getString("cat"))
                      .toString();
            }
        }

You can create a new empty array with your existing array size, and you can assign back them to your array. This may faster than other. Snipet:

package com.array.zero;
public class ArrayZero {
public static void main(String[] args) {
    // Your array with data
    int[] yourArray = { 1, 2, 3, 4, 5, 6, 7, 8, 9 };
    //Creating same sized array with 0
    int[] tempArray = new int[yourArray.length];
    Assigning temp array to replace values by zero [0]
    yourArray = tempArray;

    //testing the array size and value to be zero
    for (int item : yourArray) {
        System.out.println(item);
    }
}
}

Result :

CancelAsync doesn't actually abort your thread or anything like that. It sends a message to the worker thread that work should be cancelled via BackgroundWorker.CancellationPending. Your DoWork delegate that is being run in the background must periodically check this property and handle the cancellation itself.

The tricky part is that your DoWork delegate is probably blocking, meaning that the work you do on your DataSource must complete before you can do anything else (like check for CancellationPending). You may need to move your actual work to yet another async delegate (or maybe better yet, submit the work to the ThreadPool), and have your main worker thread poll until this inner worker thread triggers a wait state, OR it detects CancellationPending.

What's happening here is the following: You create a new file on your trunk, then you merge it into your branch. In the merge commit this file will be created in your branch also.

When you merge your branch back into the trunk, SVN tries to do the same again: It sees that a file was created in your branch, and tries to create it in your trunk in the merge commit, but it already exists! This creates a tree conflict.

The way to avoid this, is to do a special merge, a reintegration. You can achieve this with the --reintegrate switch.

You can read about this in the documentation: http://svnbook.red-bean.com/en/1.7/svn.branchmerge.basicmerging.html#svn.branchemerge.basicmerging.reintegrate

When merging your branch back to the trunk, however, the underlying mathematics are quite different. Your feature branch is now a mishmash of both duplicated trunk changes and private branch changes, so there's no simple contiguous range of revisions to copy over. By specifying the --reintegrate option, you're asking Subversion to carefully replicate only those changes unique to your branch. (And in fact, it does this by comparing the latest trunk tree with the latest branch tree: the resulting difference is exactly your branch changes!)

After reintegrating a branch it is highly advisable to remove it, otherwise you will keep getting treeconflicts whenever you merge in the other direction: from the trunk to your branch. (For exactly the same reason as described before.)

There is a way around this too, but I never tried it. You can read it in this post: Subversion branch reintegration in v1.6

To get the plugin directory you can use the Wordpress function plugin_basename($file). So you would use is as follows to extract the folder and filename of the plugin:

$plugin_directory = plugin_basename(__FILE__); 

You can combine this with the URL or the server path of the plugin directory. Therefor you can use the constants WP_PLUGIN_URL to get the plugin directory url or WP_PLUGIN_DIR to get the server path. But as Mark Jaquith mentioned in a comment below this only works if the plugins resides in the Wordpress plugin directory.

Read more about it in the Wordpress codex.

Try this, to set the focus to the first input field:

$(this).parent().siblings('div.bottom').find("input.post").focus();

npm install --save @types/lodash

https://www.npmjs.com/package/@types/lodash

The groupingBy method has the first parameter is Function<T,K> where:

@param <T> the type of the input elements

@param <K> the type of the keys

If we replace lambda with the anonymous class in your code, we can see some kind of that:

people.stream().collect(Collectors.groupingBy(new Function<Person, int>() {
            @Override
            public int apply(Person person) {
                return person.getAge();
            }
        }));

Just now change output parameter<K>. In this case, for example, I used a pair class from org.apache.commons.lang3.tuple for grouping by name and age, but you may create your own class for filtering groups as you need.

people.stream().collect(Collectors.groupingBy(new Function<Person, Pair<Integer, String>>() {
                @Override
                public YourFilter apply(Person person) {
                    return Pair.of(person.getAge(), person.getName());
                }
            }));

Finally, after replacing with lambda back, code looks like that:

Map<Pair<Integer,String>, List<Person>> peopleByAgeAndName = people.collect(Collectors.groupingBy(p -> Pair.of(person.getAge(), person.getName()), Collectors.mapping((Person p) -> p, toList())));

You can also use the mouse middle button to paste in insert mode (Linux only).

One of the reasons for me getting an error was the file name make sure the file name is Dockerfile So i figured it out, hope it might help someone.

I tried all answers but nothing worked for me. I ended up connecting to different WiFi network then I was able to debug wirelessly.

I have no clue why it didn't work with the old network

You may use NULL instead of NA. This creates a truly empty data frame.

You can do this, just wrap it in typeof()

foo.GetColumnValues(typeof(int))

public void GetColumnValues(Type type)
{
    //logic
}

Running the command prompt or Powershell ISE as an administrator fixed this for me.

Try This One:

@list_of_params varchar(20) -- value 1, 2, 5, 7, 20 

SELECT d.[Name]
FROM Department d
where @list_of_params like ('%'+ CONVERT(VARCHAR(10),d.Id)  +'%')

very simple.

private DateTime ConvertToDateTime(string strDateTime)
{
DateTime dtFinaldate; string sDateTime;
try { dtFinaldate = Convert.ToDateTime(strDateTime); }
catch (Exception e)
{
string[] sDate = strDateTime.Split('/');
sDateTime = sDate[1] + '/' + sDate[0] + '/' + sDate[2];
dtFinaldate = Convert.ToDateTime(sDateTime);
}
return dtFinaldate;
}

static T DeserializeXml<T>(string sourceXML) where T : class
{
    var serializer = new XmlSerializer(typeof(T));
    T result = null;

    using (TextReader reader = new StringReader(sourceXML))
    {
        result = (T) serializer.Deserialize(reader);
    }

    return result;
}

Current version of FF and IE and some other browsers support multiple background images in a single CSS2 declaration. Look here http://dense13.com/blog/2008/08/31/multiple-background-images-with-css2/ and here http://www.quirksmode.org/css/multiple_backgrounds.html and here http://nicolasgallagher.com/multiple-backgrounds-and-borders-with-css2/

For IE, you might consider adding a behavior. Look here: http://css3pie.com/

It also implements a lot of LAPACK functions.

If you have multiple folders in your workspace, set up the search.exclude on each folder. There's a drop-down next to WORKSPACE SETTINGS.

Folder Settings Tab

ls -l --block-size=M 

will give you a long format listing (needed to actually see the file size) and round file sizes up to the nearest MiB. If you want MB (10^6 bytes) rather than MiB (2^20 bytes) units, use --block-size=MB instead.

Or

ls -lah 

-h When used with the -l option, use unit suffixes: Byte, Kilobyte, Megabyte, Gigabyte, Terabyte and Petabyte in order to reduce the number of digits to three or less using base 2 for sizes.

man ls

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

"${foo}bar"

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

Curly braces are also unconditionally required when:

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

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

For people still getting the issue.

I face same problem and seems some .jar file missing.

so try tar -xf apache-jmeter-5.2.1.tgz in the console rather than just right click unzip. And also, try binary package if source package still has an issue. this solve my issue (I am using ubuntu)

Using Concat on the group by will work

SELECT clients.id, clients.name, portfolios.id, SUM ( portfolios.portfolio + portfolios.cash ) AS total
FROM clients, portfolios
WHERE clients.id = portfolios.client_id
GROUP BY CONCAT(portfolios.id, "-", clients.id)
ORDER BY total DESC
LIMIT 30

RPC is an old protocol based on C.It can invoke a remote procedure and make it look like a local call.RPC handles the complexities of passing that remote invocation to the server and getting the result to client.

Java RMI also achieves the same thing but slightly differently.It uses references to remote objects.So, what it does is that it sends a reference to the remote object alongwith the name of the method to invoke.It is better because it results in cleaner code in case of large programs and also distribution of objects over the network enables multiple clients to invoke methods in the server instead of establishing each connection individually.

You want to create an Object, not an Array.

Like so,

var Map = {};

Map['key1'] = 'value1';
Map['key2'] = 'value2';

You can check if the key exists in multiple ways:

Map.hasOwnProperty(key);
Map[key] != undefined // For illustration // Edit, remove null check
if (key in Map) ...

Sometimes "Nothing to be done for all" error can be caused by spaces before command in makefile rule instead of tab. Please ensure that you use tabs instead of spaces inside of your rules.

all:
<\t>$(CC) $(CFLAGS) ...

instead of

all:
    $(CC) $(CFLAGS) ...

Please see the GNU make manual for the rule syntax description: https://www.gnu.org/software/make/manual/make.html#Rule-Syntax

The 2nd call to Enable-Migrations is failing because the Configuration.cs file already exists. If you rename that class and file, you should be able to run that 2nd Enable-Migrations, which will create another Configuration.cs.

You will then need to specify which configuration you want to use when updating the databases.

Update-Database -ConfigurationTypeName MyRenamedConfiguration

You can use something like following:

Matrix matrix = new Matrix();
matrix.setRotate(mRotation,source.getWidth()/2,source.getHeight()/2);
RectF rectF = new RectF(0, 0, source.getWidth(), source.getHeight());
matrix.mapRect(rectF);
Bitmap targetBitmap = Bitmap.createBitmap(rectF.width(), rectF.height(), config);
Canvas canvas = new Canvas(targetBitmap);
canvas.drawBitmap(source, matrix, new Paint());

var obj = {
    "key1" : "k1",
    "key2" : "k2",
    "key3" : "k3"
};

if ("key1" in obj)
    console.log("has key1 in obj");

=========================================================================

To access a child key of another key

var obj = {
    "key1": "k1",
    "key2": "k2",
    "key3": "k3",
    "key4": {
        "keyF": "kf"
    }
};

if ("keyF" in obj.key4)
    console.log("has keyF in obj");

Heres the method I used in my logging library: https://github.com/goktugyil/QorumLogs

This method fills html forms inside Google Forms. Hope it helps someone using Swift.

var url = NSURL(string: urlstring)

var request = NSMutableURLRequest(URL: url!)
request.HTTPMethod = "POST"
request.setValue("application/x-www-form-urlencoded; charset=utf-8", forHTTPHeaderField: "Content-Type")
request.HTTPBody = postData.dataUsingEncoding(NSUTF8StringEncoding)
var connection = NSURLConnection(request: request, delegate: nil, startImmediately: true)

In general, you can classify any error/exception in one of three categories:

• Fatal: Not your fault, you cannot prevent them, you cannot recover from them. You should certainly not ignore them and continue, and leave your program in an unknown state. Just let the error terminate your program, there is nothing you can do.

• Boneheaded: Your own fault, most likely due to an oversight, bug or programming error. You should fix the bug. Again, you should most certainly not ignore and continue.

• Exogenous: You can expect these errors in exceptional situations, such as file not found or connection terminated. You should explicitly handle these errors, and only these.

In all cases except: pass will only leave your program in an unknown state, where it can cause more damage.

For angular 4 I have used

<img [src]="data.pic ? data.pic : 'assets/images/no-image.png' " alt="Image" title="Image">

It works for me , I hope it may use to other's also for Angular 4-5. :)

I see many (all) posts above relying on LBound/UBound calls upon yet potentially uninitialized VBA dynamic array, what causes application's inevitable death ...

Erratic code:

Dim x As Long Dim arr1() As SomeType ... x = UBound(arr1) 'crashes

Correct code:

Dim x As Long Dim arr1() As SomeType ... ReDim Preserve arr1(0 To 0) ... x = UBound(arr1)

... i.e. any code where Dim arr1() is followed immediatelly by LBound(arr1)/UBound(arr1) calls without ReDim arr1(...) in between, crashes. The roundabout is to employ an On Error Resume Next and check the Err.Number right after the LBound(arr1)/UBound(arr1) call - it should be 0 if the array is initialized, otherwise non-zero. As there is some VBA built-in misbehavior, the further check of array's limits is needed. Detailed explanation may everybody read at Chip Pearson's website (which should be celebrated as a Mankind Treasure Of VBA Wisdom ...)

Heh, that's my first post, believe it is legible.

import sys
sys.modules.keys()

An approximation of getting all imports for the current module only would be to inspect globals() for modules:

import types
def imports():
    for name, val in globals().items():
        if isinstance(val, types.ModuleType):
            yield val.__name__

This won't return local imports, or non-module imports like from x import y. Note that this returns val.__name__ so you get the original module name if you used import module as alias; yield name instead if you want the alias.

Notice that if the file's parent folder doesn't exist you'll get the same error:

IOError: [Errno 2] No such file or directory:

Below is another solution which handles this case:
(*) I used sys.stdout and print instead of f.write just to show another use case

# Make sure the file's folder exist - Create folder if doesn't exist
folder_path = 'path/to/'+folder_name+'/'
if not os.path.exists(folder_path):
     os.makedirs(folder_path)

print_to_log_file(folder_path, "Some File" ,"Some Content")

Where the internal print_to_log_file just take care of the file level:

# If you're not familiar with sys.stdout - just ignore it below (just a use case example)
def print_to_log_file(folder_path ,file_name ,content_to_write):

   #1) Save a reference to the original standard output       
    original_stdout = sys.stdout   
    
    #2) Choose the mode
    write_append_mode = 'a' #Append mode
    file_path = folder_path + file_name
    if (if not os.path.exists(file_path) ):
       write_append_mode = 'w' # Write mode
     
    #3) Perform action on file
    with open(file_path, write_append_mode) as f:
        sys.stdout = f  # Change the standard output to the file we created.
        print(file_path, content_to_write)
        sys.stdout = original_stdout  # Reset the standard output to its original value

Consider the following states:

'w'  --> Write to existing file
'w+' --> Write to file, Create it if doesn't exist
'a'  --> Append to file
'a+' --> Append to file, Create it if doesn't exist

In your case I would use a different approach and just use 'a' and 'a+'.

In your storyboard go to the Attributes inspector and set the view controller's Identifier. You can then present that view controller using the following code.

UIStoryboard *sb = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle:nil];
UIViewController *vc = [sb instantiateViewControllerWithIdentifier:@"myViewController"];
vc.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
[self presentViewController:vc animated:YES completion:NULL];

Give Mobiscroll a try. The scroller style date and time picker was especially created for interaction on touch devices. It is pretty flexible, and easily customizable. It comes with iOS/Android themes.

You can simply download the library which you want to include and copy it to libs folder of your project. Then select that file (in my case it was android-support-v4 library) right click on it and select "Add as Library"

If your chart uses both fill and color aesthetics, you can remove the legend with:

+ guides(fill=FALSE, color=FALSE)

We version and source control everything surrounding our databases:

• DDL (create and alters)
• DML (reference data, codes, etc.)
• Data Model changes (using ERwin or ER/Studio)
• Database configuration changes (permissions, security objects, general config changes)

We do all this with automated jobs using Change Manager and some custom scripts. We have Change Manager monitoring these changes and notifying when they are done.

You need to use a concrete class and not an Abstract class while deserializing. if the Abstract class has several implementations then, in that case, you can use it as below-

  @JsonTypeInfo( use = JsonTypeInfo.Id.NAME, include = JsonTypeInfo.As.PROPERTY, property = "type")
    @JsonSubTypes({ 
      @Type(value = Bike.class, name = "bike"), 
      @Type(value = Auto.class, name = "auto"), 
      @Type(value = Car.class, name = "car")
    })
    public abstract class Vehicle {
        // fields, constructors, getters, setters
    }

let suppose you are using xampp and phpmyadmin

you have file name 'ratings.txt' table name 'ratings' and database name 'movies'

if your xampp is installed in "C:\xampp\"

copy your "ratings.txt" file in "C:\xampp\mysql\data\movies" folder

LOAD DATA INFILE 'ratings.txt' INTO TABLE ratings FIELDS TERMINATED BY ',' ENCLOSED BY '"' LINES TERMINATED BY '\r\n' IGNORE 1 LINES;

Hope this can help you to omit your error if you are doing this on localhost

Try this...

I am in Windows 7 with Code::Blocks

while (true)

    char input;
    input = getch();

        break;
    case 72:

    }
}

[Update Sept 2020] Although my original answer here, from many years ago, seems to be helpful and is still getting upvotes, I now use the GSON library from Google, which I find to be more intuitive.

I've got the following code:

public void testJackson() throws IOException {  
    ObjectMapper mapper = new ObjectMapper(); 
    File from = new File("albumnList.txt"); 
    TypeReference<HashMap<String,Object>> typeRef 
            = new TypeReference<HashMap<String,Object>>() {};

    HashMap<String,Object> o = mapper.readValue(from, typeRef); 
    System.out.println("Got " + o); 
}   

It's reading from a file, but mapper.readValue() will also accept an InputStream and you can obtain an InputStream from a string by using the following:

new ByteArrayInputStream(astring.getBytes("UTF-8")); 

There's a bit more explanation about the mapper on my blog.

This regex is very short and sweet for working.

/^([+]\d{2})?\d{10}$/

Ex: +910123456789 or 0123456789

-> /^ and $/ is for starting and ending
-> The ? mark is used for conditional formatting where before question mark is available or not it will work
-> ([+]\d{2}) this indicates that the + sign with two digits '\d{2}' here you can place digit as per country
-> after the ? mark '\d{10}' this says that the digits must be 10 of length change as per your country mobile number length

This is how this regex for mobile number is working.
+ sign is used for world wide matching of number.

if you want to add the space between than you can use the

[ ]

here the square bracket represents the character sequence and a space is character for searching in regex.
for the space separated digit you can use this regex

/^([+]\d{2}[ ])?\d{10}$/

Ex: +91 0123456789

Thanks ask any question if you have.

If you look at the source code, you will see, they are calling ThreadPoolExecutor. internally and setting their properties. You can create your one to have a better control of your requirement.

public static ExecutorService newFixedThreadPool(int nThreads) {
   return new ThreadPoolExecutor(nThreads, nThreads,0L, TimeUnit.MILLISECONDS,
new LinkedBlockingQueue<Runnable>());
}

public static ExecutorService newCachedThreadPool() {
        return new ThreadPoolExecutor(0, Integer.MAX_VALUE,
                                      60L, TimeUnit.SECONDS,
                                      new SynchronousQueue<Runnable>());
}

YourClassName.YourStaticFieldName

For your static field would look like:

public class StaticExample 
{
   public static double Pi = 3.14;
}

From another class, you can access the staic field as follows:

    class Program
    {
     static void Main(string[] args)
     {
         double radius = 6;
         double areaOfCircle = 0;

         areaOfCircle = StaticExample.Pi * radius * radius;
         Console.WriteLine("Area = "+areaOfCircle);

         Console.ReadKey();
     }
  }

Here is a link to a 4Guys article on how you can format Dates and Times using the ToString() method by passing in a custom format string.

http://www.aspfaqs.com/aspfaqs/ShowFAQ.asp?FAQID=181

Just in case it goes away here is one of the examples.

'Create a var. named rightNow and set it to the current date/time
Dim rightNow as DateTime = DateTime.Now
Dim s as String 'create a string

s = rightNow.ToString("MMM dd, yyyy")

Since his link is broken here is a link to the DateTimeFormatInfo class that makes those formatting options possible.

http://msdn.microsoft.com/en-us/library/system.globalization.datetimeformatinfo.aspx

It's probably a little more consistent to do something like that rather than use a substring, but who knows.

I believe you are looking for the setTimeout function.

To make your code a little neater, define a separate function for onclick in a <script> block:

function myClick() {
  setTimeout(
    function() {
      document.getElementById('div1').style.display='none';
      document.getElementById('div2').style.display='none';
    }, 5000);
}

then call your function from onclick

onclick="myClick();"

First of all, do a backup of your needed databases with mysqldump

Note: If you want to restore later, just backup your relevant databases, and not the WHOLE, because the whole database might actually be the reason you need to purge and reinstall).

In total, do this:

sudo service mysql stop  #or mysqld
sudo killall -9 mysql
sudo killall -9 mysqld
sudo apt-get remove --purge mysql-server mysql-client mysql-common
sudo apt-get autoremove
sudo apt-get autoclean
sudo deluser -f mysql
sudo rm -rf /var/lib/mysql
sudo apt-get purge mysql-server-core-5.7
sudo apt-get purge mysql-client-core-5.7
sudo rm -rf /var/log/mysql
sudo rm -rf /etc/mysql

All above commands in single line (just copy and paste):

sudo service mysql stop && sudo killall -9 mysql && sudo killall -9 mysqld && sudo apt-get remove --purge mysql-server mysql-client mysql-common && sudo apt-get autoremove && sudo apt-get autoclean && sudo deluser mysql && sudo rm -rf /var/lib/mysql && sudo apt-get purge mysql-server-core-5.7 && sudo apt-get purge mysql-client-core-5.7 && sudo rm -rf /var/log/mysql && sudo rm -rf /etc/mysql

Since this issue is still active, here's another approach:

• ES6/2015

function mergeDeep(...objects) {_x000D_

  _x000D_
  return objects.reduce((prev, obj) => {_x000D_

        prev[key] = pVal.concat(...oVal);_x000D_
      }_x000D_
      else if (isObject(pVal) && isObject(oVal)) {_x000D_
        prev[key] = mergeDeep(pVal, oVal);_x000D_
      }_x000D_
      else {_x000D_
        prev[key] = oVal;_x000D_

    });_x000D_
    _x000D_
    return prev;_x000D_

Less no longer evaluates expression inside calc by default since v3.00.

Original answer (Less v1.x...2.x):

Do this:

body { width: calc(~"100% - 250px - 1.5em"); }

In Less 1.4.0 we will have a strictMaths option which requires all Less calculations to be within brackets, so the calc will work "out-of-the-box". This is an option since it is a major breaking change. Early betas of 1.4.0 had this option on by default. The release version has it off by default.

Yes:

<input required title="Enter something OR ELSE." /> 

The title attribute will be used to notify the user of a problem.

Open finder>Library>Developer>CoreSimulator>Devices

Then Change Arrangement icon from finder select Date Added

Select your app >data>Container>data>Applications>

choose your app >Documents>Here is your db file

In my case:

/Users/pluto/Library/Developer/CoreSimulator/Devices/A75107D2-A535-415A-865D-978B2555370B/data/Containers/Data/Application/265A12BC-FF5B-4235-B5EF-6022B83754B4/Documents/dboPhotoBucket.sqlite

Otherwise do this :

NSLog(@"app dir: %@",[[[NSFileManager defaultManager] URLsForDirectory:NSDocumentDirectory inDomains:NSUserDomainMask] lastObject]); 

- It will print the full path to data folder.

Swift:

let dirPaths = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true)
println("App Path: \(dirPaths)")

Use python's binascii module

import binascii

binFile = open('somebinaryfile.exe','rb')
binaryData = binFile.read(8)

print binascii.hexlify(binaryData)

You could also rewrite the code to remove the nested 'If' statement completely.

Today I ran into the same error, however, i was using Android Studio 1.0.2. What i did tot fix the problem was that i started a project with minimum SDK 4.4 (API 19) so when i checked the version i noticed that at File->ProjectStructure->app i found Android 5 as a compile SDK Version. I changed that back to 4.4.

For TFS 2013:

Start in VisualStudio-Team Explorer, in the PendingChanges Dialog undo the Changes whith the state [add], which should be ignored.

Visual Studio will detect the Add(s) again. Click On "Detected: x add(s)"-in Excluded Changes

In the opened "Promote Cadidate Changes"-Dialog You can easy exclude Files and Folders with the Contextmenu. Options are:

• Ignore this item
• Ignore by extension
• Ignore by file name
• Ignore by ffolder (yes ffolder, TFS 2013 Update 4/Visual Studio 2013 Premium Update 4)

Don't forget to Check In the changed .tfignore-File.

For VS 2015/2017:

The same procedure: In the "Excluded Changes Tab" in TeamExplorer\Pending Changes click on Detected: xxx add(s)

The "Promote Candidate Changes" Dialog opens, and on the entries you can Right-Click for the Contextmenu. Typo is fixed now :-)

The following code uses both data.table and fastmatch for increased speed.

library("data.table")
library("fastmatch")

a1 <- setDT(data.frame(a = 1:5, b=letters[1:5]))
a2 <- setDT(data.frame(a = 1:3, b=letters[1:3]))

compare_rows <- a1$a %fin% a2$a
# the %fin% function comes from the `fastmatch` package

added_rows <- a1[which(compare_rows == FALSE)]

added_rows

#    a b
# 1: 4 d
# 2: 5 e

If one wants to have the conf\logging.properties read one must (see also here) dump this file into the Servers\Tomcat v7.0 Server at localhost-config\ folder and then add the lines :

-Djava.util.logging.config.file="${workspace_loc}\Servers\Tomcat v7.0 Server at localhost-config\logging.properties" -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager

to the VM arguments of the launch configuration one is using.

This may have taken a restart or two (or not) but finally I saw in the console in bright red :

FINE: No TLD files were found in [file:/C:/Dropbox/eclipse_workspaces/javaEE/.metadata/.plugins/org.eclipse.wst.server.core/tmp0/wtpwebapps/ted2012/WEB-INF/lib/logback-classic-1.0.7.jar]. Consider adding the JAR to the tomcat.util.scan.DefaultJarScanner.jarsToSkip or org.apache.catalina.startup.TldConfig.jarsToSkip property in CATALINA_BASE/conf/catalina.properties file. //etc

I still don't know when exactly this FINE warning appears - does not appear immediately on tomcat launch EDIT: from the comment by @Stephan: "The FINE warning appears each time any change is done in the JSP file".

Bonus: To make the warning go away add in catalina.properties :

# Additional JARs (over and above the default JARs listed above) to skip when
# scanning for TLDs. The list must be a comma separated list of JAR file names.
org.apache.catalina.startup.TldConfig.jarsToSkip=logback-classic-1.0.7.jar,\

Q1) Here are couple things to read or google more :

Main differences between SOAP and RESTful web services in java http://www.ajaxonomy.com/2008/xml/web-services-part-1-soap-vs-rest

It's up to you what do you want to learn first. I'd recommend you take a look at the CXF framework. You can build both rest/soap services.

Q2) Here are couple of good tutorials for soap (I had them bookmarked) :

http://united-coders.com/phillip-steffensen/developing-a-simple-soap-webservice-using-spring-301-and-apache-cxf-226

http://www.benmccann.com/blog/web-services-tutorial-with-apache-cxf/

http://www.mastertheboss.com/web-interfaces/337-apache-cxf-interceptors.html

Best way to learn is not just reading tutorials. But you would first go trough tutorials to get a basic idea so you can see that you're able to produce something(or not) and that would get you motivated.

SO is great way to learn particular technology (or more), people ask lot of wierd questions, and there are ever weirder answers. But overall you'll learn about ways to solve issues on other way. Maybe you didn't know of that way, maybe you couldn't thought of it by yourself.

Subscribe to couple of tags that are interesting to you and be persistent, ask good questions and try to give good answers and I guarantee you that you'll learn this as time passes (if you're persistent that is).

Q3) You will have to answer this one yourself. First by deciding what you're going to build, after all you will need to think of some mini project or something and take it from there.

If you decide to use CXF as your framework for building either REST/SOAP services I'd recommend you look up this book Apache CXF Web Service Development. It's fantastic, not hard to read and not too big either (win win).

In order to show all items / simulate combobox behavior, you should first ensure you have set the minLength option to 0 (default is 1). Then you can bind the click event to perform a search with the empty string.

$('inputSelector').autocomplete({ minLength: 0 });
$('inputSelector').click(function() { $(this).autocomplete("search", ""); });

Delete web.config file and insert again. http://forums.asp.net/post/916808.aspx

Use the replace function in js:

var emailAdd = $(this).text().replace(/ /g,'');

That will remove all the spaces

If you want to remove the leading and trailing whitespace only, use the jQuery $.trim method :

var emailAdd = $.trim($(this).text());

This particular error implies that one of the variables being used in the arithmetic on the line has a shape incompatible with another on the same line (i.e., both different and non-scalar). Since n and the output of np.add.reduce() are both scalars, this implies that the problem lies with xm and ym, the two of which are simply your x and y inputs minus their respective means.

Based on this, my guess is that your x and y inputs have different shapes from one another, making them incompatible for element-wise multiplication.

** Technically, it's not that variables on the same line have incompatible shapes. The only problem is when two variables being added, multiplied, etc., have incompatible shapes, whether the variables are temporary (e.g., function output) or not. Two variables with different shapes on the same line are fine as long as something else corrects the issue before the mathematical expression is evaluated.

Run your code under a JRockit JVM, then use JRCMD <PID> print_class_summary

This will output all loaded classes, one on each line.

int(hexstring, 16) does the trick, and works with and without the 0x prefix:

>>> int("a", 16)
10
>>> int("0xa", 16)
10

I always use the iPhone configuration utility for this. Allows much more control and is faster - you don't have to sync the whole device.

I had a similar problem with my Nexus 4(Android version 4.4.2), it wasn't listed in adb devices.

Make sure USB debugging is enabled from device, and do the following on your PC:

1. Update Android SDK (Google USB Driver)

2. From PC Control Panel, System -> Device manager -> Right click Nexus 4 -> Update driver.

3. Set android-sdk-folder\extras\google\usb_driver as path to search, include subfolders checked.

If windows tells you that the driver is up to date, just uninstall the driver (right click on nexu4 -> uninstall driver) and start from step 2 again.

After that, open a cmd and type adb kill-server and then a adb devices, now it will include your device.

Trailing whitespace is any spaces or tabs after the last non-whitespace character on the line until the newline.

In your posted question, there is one extra space after try:, and there are 12 extra spaces after pass:

>>> post_text = '''\
...             if self.tagname and self.tagname2 in list1:
...                 try: 
...                     question = soup.find("div", "post-text")
...                     title = soup.find("a", "question-hyperlink")
...                     self.list2.append(str(title)+str(question)+url)
...                     current += 1
...                 except AttributeError:
...                     pass            
...             logging.info("%s questions passed, %s questions \
...                 collected" % (count, current))
...             count += 1

>>> for line in post_text.splitlines():

... 
'                try: '
'                    pass            '

See where the strings end? There are spaces before the lines (indentation), but also spaces after.

Use your editor to find the end of the line and backspace. Many modern text editors can also automatically remove trailing whitespace from the end of the line, for example every time you save a file.

Also, take a look at FrameLayout, that's how the Camera's Gallery application implements the Zoom buttons overlay.

Many solutions have been provided, but I have not seen this one, which uses package chron:

hours = times(strftime(times, format="%T"))
plot(val~hours)

If you know part of the subnet (i.e. 10.3 in this example), then this will grab any addresses that are in the given subnet:

PS C:\> [System.Net.Dns]::GetHostAddresses("MyPC") | foreach { $_.IPAddressToString | findstr "10.3."}

This is a very simple solution, but it works for me:

<!--TEXT-AREA-->_x000D_
<textarea id="textBox1" name="content" TextMode="MultiLine" onkeyup="setHeight('textBox1');" onkeydown="setHeight('textBox1');">Hello World</textarea>_x000D_
_x000D_
<!--JAVASCRIPT-->_x000D_
<script type="text/javascript">_x000D_
function setHeight(fieldId){_x000D_
    document.getElementById(fieldId).style.height = document.getElementById(fieldId).scrollHeight+'px';_x000D_
}_x000D_
setHeight('textBox1');_x000D_
</script>

Use dataType casting. For example:

// converting from double to float:
double someValue;
// cast someValue to float!
float newValue = (float)someValue;

Cheers!

Note:

Integers are whole numbers, e.g. 10, 400, or -5.

Floating point numbers (floats) have decimal points and decimal places, for example 12.5, and 56.7786543.

Doubles are a specific type of floating point number that have greater precision than standard floating point numbers (meaning that they are accurate to a greater number of decimal places).

The file may be existing but may have a different path. Try writing the absolute path for the file.

Try os.listdir() function to check that atleast python sees the file.

You can access any LayoutParams from code using View.getLayoutParams. You just have to be very aware of what LayoutParams your accessing. This is normally achieved by checking the containing ViewGroup if it has a LayoutParams inner child then that's the one you should use. In your case it's RelativeLayout.LayoutParams. You'll be using RelativeLayout.LayoutParams#addRule(int verb) and RelativeLayout.LayoutParams#addRule(int verb, int anchor)

You can get to it via code:

RelativeLayout.LayoutParams params = (RelativeLayout.LayoutParams)button.getLayoutParams();
params.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);
params.addRule(RelativeLayout.LEFT_OF, R.id.id_to_be_left_of);

button.setLayoutParams(params); //causes layout update

x.transpose[6][3..8] or x[3..8].map {|r| r [6]} would give what you want.

Example:

a = [ [1,  2,  3,  4,  5],
      [6,  7,  8,  9,  10],
      [11, 12, 13, 14, 15],
      [21, 22, 23, 24, 25]
    ]

#a[1..2][2]  -> [8,13]
puts a.transpose[2][1..2].inspect   # [8,13]
puts a[1..2].map {|r| r[2]}.inspect  # [8,13]

I found an important step to add to this - after you've installed the SDK, go to your project properties and change Configuration Properties->General->Platform Toolset from v100 or whatever it is to Windows7.1SDK. This changes $(WindowsSdkDir) to the proper place and seemed to solve some other difficulties I was encountering as well.

You're getting errors 'table liam does not exist' because the table's name is Liam which is not the same as liam. MySQL table names are case sensitive.

First - most classes will never need to be thread-safe. Use YAGNI: only apply thread-safety when you know you actually are going to use it (and test it).

For the method-level stuff, there is [MethodImpl]:

[MethodImpl(MethodImplOptions.Synchronized)]
public void SomeMethod() {/* code */}

This can also be used on accessors (properties and events):

private int i;
public int SomeProperty
{
    [MethodImpl(MethodImplOptions.Synchronized)]
    get { return i; }
    [MethodImpl(MethodImplOptions.Synchronized)]
    set { i = value; }
}

Note that field-like events are synchronized by default, while auto-implemented properties are not:

public int SomeProperty {get;set;} // not synchronized
public event EventHandler SomeEvent; // synchronized

Personally, I don't like the implementation of MethodImpl as it locks this or typeof(Foo) - which is against best practice. The preferred option is to use your own locks:

private readonly object syncLock = new object();
public void SomeMethod() {
    lock(syncLock) { /* code */ }
}

Note that for field-like events, the locking implementation is dependent on the compiler; in older Microsoft compilers it is a lock(this) / lock(Type) - however, in more recent compilers it uses Interlocked updates - so thread-safe without the nasty parts.

This allows more granular usage, and allows use of Monitor.Wait/Monitor.Pulse etc to communicate between threads.

I finally solved this problem, I had to go to the Developer options from the Settings in the Emulator, then scrolled down a little, turned on the USB debugging. Instantly my device was recognized online, and I no longer faced that issue. I tried restarting android studio and emulator, killing adb process, but those did not work.

Here's a real world example with the use of non-minified versus minified assets in your layout.

Web.Config

<appSettings>

   <add key="Environment" value="Dev" />

 </appSettings>

Razor Template - use that var above like this:

@if (System.Configuration.ConfigurationManager.AppSettings["Environment"] == "Dev")
{    
    <link type="text/css" rel="stylesheet" href="@Url.Content("~/Content/styles/theme.css" )">    

}else{        

   <link type="text/css" rel="stylesheet" href="@Url.Content("~/Content/styles/blue_theme.min.css" )">    

}

Modern browsers provide URLSearchParams interface to work with search params. Which has delete method that removes param by name.

if (typeof URLSearchParams !== 'undefined') {_x000D_
  const params = new URLSearchParams('param1=1&param2=2&param3=3')_x000D_
  _x000D_
  console.log(params.toString())_x000D_
  _x000D_
  params.delete('param2')_x000D_
  _x000D_
  console.log(params.toString())_x000D_
_x000D_
} else {_x000D_
  console.log(`Your browser ${navigator.appVersion} does not support URLSearchParams`)_x000D_
}

for speed you can do this

WHERE date(created_at) ='2019-10-21'

I've been using some simple CSS and it seems to remove them and work fine.

input[type=number]::-webkit-inner-spin-button, _x000D_
input[type=number]::-webkit-outer-spin-button { _x000D_
    -webkit-appearance: none;_x000D_
    -moz-appearance: none;_x000D_
    appearance: none;_x000D_

It turns out the answer was ridiculously simple, but mystifying as to why it was necessary.

In the IIS Manager on the server, I set the application pool for my web application to not allow 32-bit assemblies.

It seems it assumes, on a 64-bit system, that you must want the 32 bit assembly. Bizarre.

useComponentWillMount hook

export const useComponentWillMount = (func) => {
    const willMount = useRef(true)

    if (willMount.current) func()

    willMount.current = false
}

// or
export const useComponentWillMount = (func) => {
    useMemo(func, [])
}

Discussion

In class components componentWillMount is considered legacy (source 1, source2). However, this shouldn't apply to functional components and a hook based solution. Class component componentWillMount is deprecated since it might run more than once, and there is an alternative - using the constructor. Those considerations aren't relevant for a functional component.

My experience is that such a hook could be a saver when timing/sequence is critical. I'm interested to know what is your use case - comments are welcome.

useComponentDidMount hook

Alternatively, use componentDidMount hook.

const useComponentDidMount = func => useEffect(func, []);

It will run only once, after component has mounted(initial render to the dom).

Demo

const Component = (props) => {
  useComponentWillMount(() => console.log("Runs only once before component mounts"));
  useComponentDidMount(() => console.log("Runs only once after component mounts"));
  ...

  return (
    <div>{...}</div>
  );
}

You need xlutils.copy. Try something like this:

from xlutils.copy import copy
w = copy('book1.xls')
w.get_sheet(0).write(0,0,"foo")
w.save('book2.xls')

Keep in mind you can't overwrite cells by default as noted in this question.

If Your issue is when you touch/tap on android and whole div covered by blue transparent color! Then you need to just change the

CURSOR : POINTER; to CURSOR : DEFAULT;

use mediaQuery to hide in mobile phone/Tablet.

This works for me.

Try this:

HTML:

<input type="checkbox" value="FALSE" />

jQ:

$("input[type='checkbox']").on('change', function(){
  $(this).val(this.checked ? "TRUE" : "FALSE");
})

jsfiddle

Please bear in mind that unchecked checkbox will not be submitted in regular form, and you should use hidden filed in order to do it.

I personaly prefer to use plural names to represent a set, it just "sounds" better to my relational mind.

At this exact moment i am using singular names to define a data model for my company, because most of the people at work feel more confortable with it. Sometimes you just have to make life easier to everyone instead of imposing your personal preferences. (that's how i ended up in this thread, to get a confirmation on what should be the "best practice" for naming tables)

After reading all the arguing in this thread, i reached one conclusion:

I like my pancakes with honey, no matter what everybody's favorite flavour is. But if i am cooking for other people, i will try to serve them something they like.

In management studio you can set the timeout in seconds. menu Tools => Options set the field and then Ok

C++ is a language and Visual C++ is a compiler for that language. Certainly, it (and every other compiler) introduces tiny modifications to the language, but the language recognized is mainly the same.

I prefer to use <limits> to check for an int until it is passed.

#include <iostream>
#include <limits> //std::numeric_limits

using std::cout, std::endl, std::cin;

int main() {
    int num;
    while(!(cin >> num)){  //check the Input format for integer the right way
        cin.clear();
        cin.ignore(std::numeric_limits<std::streamsize>::max(), '\n');
        cout << "Invalid input.  Reenter the number: ";
      };

    cout << "output= " << num << endl;

    return 0;
}

Do not bother with encoding. Use a text node instead. Data in text node is guaranteed to be treated as text.

document.body.appendChild(document.createTextNode("Your&funky<text>here"))

this inside of doThings is the window object. Try this instead:

var doThings = function (element) {
    var eventHandler = function(ev, func){
        if (element[ev] == undefined) {
            return;
        }

        element[ev] = function(e){
            func(e, element);
        }
    };

    return {
        eventHandler: eventHandler
    };
};

This is a great example of using the wrong tool for the job. Regular expressions do not handle arbitrarily nested sub-matches very well. What you should do instead is use a real lexer and parser (a grammar for C++ should be easy to find) and look for unexpectedly empty loop bodies.

You didn't bind all your bindings here

$sql = "SELECT SQL_CALC_FOUND_ROWS *, UNIX_TIMESTAMP(publicationDate) AS publicationDate     FROM comments WHERE articleid = :art 
ORDER BY " . mysqli_escape_string($order) . " LIMIT :numRows";

$st = $conn->prepare( $sql );
$st->bindValue( ":art", $art, PDO::PARAM_INT );

You've declared a binding called :numRows but you never actually bind anything to it.

UPDATE 2019: I keep getting upvotes on this and that reminded me of another suggestion

Double quotes are string interpolation in PHP, so if you're going to use variables in a double quotes string, it's pointless to use the concat operator. On the flip side, single quotes are not string interpolation, so if you've only got like one variable at the end of a string it can make sense, or just use it for the whole string.

In fact, there's a micro op available here since the interpreter doesn't care about parsing the string for variables. The boost is nearly unnoticable and totally ignorable on a small scale. However, in a very large application, especially good old legacy monoliths, there can be a noticeable performance increase if strings are used like this. (and IMO, it's easier to read anyway)

From all I have read you cannot do exactly what you want without javascript. If you float left before text

<div style="float:left;">widget</div> here is some CONTENT, etc.

Your content wraps as expected. But your widget is in the top left. If you instead put the float after the content

here is some CONTENT, etc. <div style="float:left;">widget</div>

Then your content will wrap the last line to the right of the widget if the last line of content can fit to the right of the widget, otherwise no wrapping is done. To make borders and backgrounds actually include the floated area in the previous example, most people add:

here is some CONTENT, etc. <div style="float:left;">widget</div><div style="clear:both;"></div>

In your question you are using bootstrap which just adds row-fluid::after { content: ""} which resolves the border/background issue.

Moving your content up will give you the one line wrap : http://jsfiddle.net/jJNPY/34/

  <div class="container-fluid">
  <div class="row-fluid">
    <div class="offset1 span8 pull-right">
    ... Widget 1...
    </div>
    .... a lot of content ....
    <div class="span8" style="margin-left: 0;">
    ... Widget 2...
    </div>


  </div>

Assuming one has a simple setup (CentOS 7, Apache 2.4.x, and PHP 5.6.20) and only one website (not assuming virtual hosting) ...

In the PHP sense, $_SERVER['SERVER_NAME'] is an element PHP registers in the $_SERVER superglobal based on your Apache configuration (**ServerName** directive with UseCanonicalName On ) in httpd.conf (be it from an included virtual host configuration file, whatever, etc ...). HTTP_HOST is derived from the HTTP host header. Treat this as user input. Filter and validate before using.

Here is an example of where I use $_SERVER['SERVER_NAME'] as the basis for a comparison. The following method is from a concrete child class I made named ServerValidator (child of Validator). ServerValidator checks six or seven elements in $_SERVER before using them.

In determining if the HTTP request is POST, I use this method.

public function isPOST()
{
    return (($this->requestMethod === 'POST')    &&  // Ignore
            $this->hasTokenTimeLeft()            &&  // Ignore
            $this->hasSameGETandPOSTIdentities() &&  // Ingore
            ($this->httpHost === filter_input(INPUT_SERVER, 'SERVER_NAME')));
}

By the time this method is called, all filtering and validating of relevant $_SERVER elements would have occurred (and relevant properties set).

The line ...

($this->httpHost === filter_input(INPUT_SERVER, 'SERVER_NAME')

... checks that the $_SERVER['HTTP_HOST'] value (ultimately derived from the requested host HTTP header) matches $_SERVER['SERVER_NAME'].

Now, I am using superglobal speak to explain my example, but that is just because some people are unfamiliar with INPUT_GET, INPUT_POST, and INPUT_SERVER in regards to filter_input_array().

The bottom line is, I do not handle POST requests on my server unless all four conditions are met. Hence, in terms of POST requests, failure to provide an HTTP host header (presence tested for earlier) spells doom for strict HTTP 1.0 browsers. Moreover, the requested host must match the value for ServerName in the httpd.conf, and, by extention, the value for $_SERVER('SERVER_NAME') in the $_SERVER superglobal. Again, I would be using INPUT_SERVER with the PHP filter functions, but you catch my drift.

Keep in mind that Apache frequently uses ServerName in standard redirects (such as leaving the trailing slash off a URL: Example, http://www.example.com becoming http://www.example.com/), even if you are not using URL rewriting.

I use $_SERVER['SERVER_NAME'] as the standard, not $_SERVER['HTTP_HOST']. There is a lot of back and forth on this issue. $_SERVER['HTTP_HOST'] could be empty, so this should not be the basis for creating code conventions such as my public method above. But, just because both may be set does not guarantee they will be equal. Testing is the best way to know for sure (bearing in mind Apache version and PHP version).

From the docs

To whitelist an entire hash of parameters, the permit! method can be used

params.require(:log_entry).permit!

Nested attributes are in the form of a hash. In my app, I have a Question.rb model accept nested attributes for an Answer.rb model (where the user creates answer choices for a question he creates). In the questions_controller, I do this

  def question_params

      params.require(:question).permit!

  end

Everything in the question hash is permitted, including the nested answer attributes. This also works if the nested attributes are in the form of an array.

Having said that, I wonder if there's a security concern with this approach because it basically permits anything that's inside the hash without specifying exactly what it is, which seems contrary to the purpose of strong parameters.

You can do that for your entire script by using something like that at the beginning of your script :

#!/usr/bin/env bash

test x$1 = x$'\x00' && shift || { set -o pipefail ; ( exec 2>&1 ; $0 $'\x00' "$@" ) | tee mylogfile ; exit $? ; }

# do whaetever you want

This redirect both stderr and stdout outputs to the file called mylogfile and let everything goes to stdout at the same time.

It is used some stupid tricks :

• use exec without command to setup redirections,
• use tee to duplicates outputs,
• restart the script with the wanted redirections,
• use a special first parameter (a simple NUL character specified by the $'string' special bash notation) to specify that the script is restarted (no equivalent parameter may be used by your original work),
• try to preserve the original exit status when restarting the script using the pipefail option.

Ugly but useful for me in certain situations.

Fiddle showing that it works: http://jsfiddle.net/trott/5vu28/.

If you really want this to be on a single line in the source file, you could insert the HTML character references for a line feed and a carriage return as shown in the answer from @Bakudan:

Based on my experience, solution which is fine(the best) when keys are not important:

$cart = [];
$cart[] = 13;
$cart[] = "foo";
$cart[] = obj;

This is a python pointer (different of c/c++)

Better yet use a oneliner:

Contrary to what pointy says, the blur() method does exist and is a part of the w3c standard. The following exaple will work in every modern browser (including IE):

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<html>
    <head>
        <title>Javascript test</title>
        <script type="text/javascript" language="javascript">
            window.onload = function()
            {
                var field = document.getElementById("field");
                var link = document.getElementById("link");
                var output = document.getElementById("output");

                field.onfocus = function() { output.innerHTML += "<br/>field.onfocus()"; };
                field.onblur = function() { output.innerHTML += "<br/>field.onblur()"; };
                link.onmouseover = function() { field.blur(); };
            };
        </script>
    </head>
    <body>
        <form name="MyForm">
            <input type="text" name="field" id="field" />
            <a href="javascript:void(0);" id="link">Blur field on hover</a>
            <div id="output"></div>
        </form>
    </body>
</html>

Note that I used link.onmouseover instead of link.onclick, because otherwise the click itself would have removed the focus.

To set to default Excel type Date (defaulted to OS level locale /-> i.e. xlsx will look different when opened by a German or British person/ and flagged with an asterisk if you choose it in Excel's cell format chooser) you should:

    CellStyle cellStyle = xssfWorkbook.createCellStyle();
    cellStyle.setDataFormat((short)14);
    cell.setCellStyle(cellStyle);

I did it with xlsx and it worked fine.

You can put an image into ::before pseudoelement and set the same dimensions for as is the image + add overflow:hidden, like:

li a::before{
  content:url('img');
  width:20px;
  height:10px
}

a {
  overflow:hidden;
  width:20px;
  height:10px
}

Instead of use img src="", try to create a div and set background-image as the image you want.

Right now it's working for me.

example:

App.js

import React, { Component } from 'react';
import './App.css';



class App extends Component {

  render() {
    return (
      <div>
        <div className="myImage"> </div>
      </div>
    );
  }
}

export default App;

App.css

.myImage {
  width: 60px;
  height: 60px;
  background-image: url("./icons/add-circle.png");
  background-repeat: no-repeat;
  background-size: 100%;
}

If you need to target multiple classes use:

#main_text .title, #main_text .title2 {
  /* Properties */
}

Here's how to pick a random sample out of each group:

SELECT GROUPING_COLUMN, 
       MIN (COLUMN_NAME) KEEP (DENSE_RANK FIRST ORDER BY DBMS_RANDOM.VALUE) 
         AS RANDOM_SAMPLE
FROM TABLE_NAME
GROUP BY GROUPING_COLUMN
ORDER BY GROUPING_COLUMN;

I'm not sure how efficient it is, but if you have a lot of categories and sub-categories, this seems to do the job nicely.

The C++ 11 way is to use std::stod and std::to_string. Both work in Visual Studio 11.

My environment:

• Ubuntu 15.10
• Python 3.5

Since none of the previous answers worked for me, I downloaded OpenCV 3.0 from http://opencv.org/downloads.html and followed the installation manual. I used the following cmake command:

$ ~/Programs/opencv-3.0.0$ cmake -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=/usr/local -D PYTHON3_EXECUTABLE=/usr/bin/python3.5 -D PYTHON_INCLUDE_DIR=/usr/include/python3.5 -D PYTHON_INCLUDE_DIR2=/usr/include/x86_64-linux-gnu/python3.5m -D PYTHON_LIBRARY=/usr/lib/x86_64-linux-gnu/libpython3.5m.so -D PYTHON3_NUMPY_INCLUDE_DIRS=/usr/lib/python3/dist-packages/numpy/core/include/ -D PYTHON3_PACKAGES_PATH=/usr/lib/python3/dist-packages ..

Each step of the tutorial is important. Particularly, don't forget to call sudo make install.

Kotlin code that works for me:

 private fun takePhotoFromCamera() {
          val intent = Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE)
        startActivityForResult(intent, PERMISSIONS_REQUEST_TAKE_PICTURE_CAMERA)
      }

And get Result :

 override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
    super.onActivityResult(requestCode, resultCode, data)
 if (requestCode == PERMISSIONS_REQUEST_TAKE_PICTURE_CAMERA) {
         if (resultCode == Activity.RESULT_OK) {
           val photo: Bitmap? =  MediaStore.Images.Media.getBitmap(this.contentResolver, Uri.parse( data!!.dataString)   )
            // Do something here : set image to an ImageView or save it ..   
              imgV_pic.imageBitmap = photo 
        } else if (resultCode == Activity.RESULT_CANCELED) {
            Log.i(TAG, "Camera  , RESULT_CANCELED ")
        }

    }

}

and don't forget to declare request code:

companion object {
 const val PERMISSIONS_REQUEST_TAKE_PICTURE_CAMERA = 300
  }

No.

From the cron man page:

...cron will then examine the modification time on all crontabs and reload those which have changed. Thus cron need not be restarted whenever a crontab file is modified

But if you just want to make sure its done anyway,

sudo service cron reload

or

/etc/init.d/cron reload

You were just missing the second half of the column statement telling it to remove the entire column, since most normal Ranges start with a Column Letter, it was looking for a number and didn't get one. The ":" gets the whole column, or row.

I think what you were looking for in your Range was this:

Range("C:C,F:F,I:I,L:L,O:O,R:R").Delete

Just change the column letters to match your needs.

Yes, 4,2 means "4 digits total, 2 of which are after the decimal place". That translates to a number in the format of 00.00. Beyond that, you'll have to show us your SQL query. PHP won't translate 3.80 into 99.99 without good reason. Perhaps you've misaligned your fields/values in the query and are trying to insert a larger number that belongs in another field.

The question of speed is irrelevant without a specific speed problem.

If you are writing SQL code to make a change to an existing row, you UPDATE it. Anything else is incorrect.

If you're going to break the rules of how code should work, then you'd better have a damn good, quantified reason for it, and not a vague idea of "This way is faster", when you don't have any idea what "faster" is.

The problem is because you haven't set JDK version properly.You should use jdk 7 for major number 51. Like this:

JAVA_HOME=/usr/java/jdk1.7.0_79

By converting the matrix to array by using

n12 = np.squeeze(np.asarray(n2))

X12 = np.squeeze(np.asarray(x1))

solved the issue.

You need to enclose your class in { and }. A few extra pointers: According to the Java coding conventions, you should

• Put your { on the same line as the method declaration:
• Name your classes using CamelCase (with initial capital letter)
• Name your methods using camelCase (with small initial letter)

Here's how I would write it:

public class ModMyMod extends BaseMod {

    public String version() {
         return "1.2_02";
    }

    public void addRecipes(CraftingManager recipes) {
       recipes.addRecipe(new ItemStack(Item.diamond), new Object[] {
          "#", Character.valueOf('#'), Block.dirt
       });
    }
}

$('form#register input[required]')

It will only return inputs which have required attribute.

A couple of issues

• You're not limiting it to files, so when it finds a matching directory it will list every file within it.
• You can't use > in -exec without something like bash -c '... > ...'. Though the > will overwrite the file, so you want to redirect the entire find anyway rather than each -exec.
• +30 is older than 30 days, -30 would be modified in last 30 days.
• -exec really isn't needed, you could list everything with various -printf options.

Something like below should work

find . -type f -mtime -30 -exec ls -l {} \; > last30days.txt

Example with -printf

find . -type f -mtime -30 -printf "%M %u %g %TR %TD %p\n" > last30days.txt

This will list files in format "permissions owner group time date filename". -printf is generally preferable to -exec in cases where you don't have to do anything complicated. This is because it will run faster as a result of not having to execute subshells for each -exec. Depending on the version of find, you may also be able to use -ls, which has a similar format to above.

Developed this method:

You NEED a table that has an unique value that can be ordered.

If you want rows 10,000 to 25,000 and your Table has 40,000 rows, first you need to get the starting point and total rows:

int start = 40000 - 10000;

int total = 25000 - 10000;

And then pass these by code to the query:

SELECT * FROM 
(SELECT * FROM schema.mytable 
ORDER BY userId DESC fetch first {start} rows only ) AS mini 
ORDER BY mini.userId ASC fetch first {total} rows only

If you only need the names of the remote repositories (and not any of the other data), a simple git remote is enough.

$ git remote
iqandreas
octopress
origin

You have strange expectations. If you gave the chain of arguments that led you to them, we might spot the flaw in them. As it is, I can only give a short primer on generics, hoping to touch on the points you might have misunderstood.

ArrayList<? extends Object> is an ArrayList whose type parameter is known to be Object or a subtype thereof. (Yes, extends in type bounds has a meaning other than direct subclass). Since only reference types can be type parameters, this is actually equivalent to ArrayList<?>.

That is, you can put an ArrayList<String> into a variable declared with ArrayList<?>. That's why a1.add(3) is a compile time error. a1's declared type permits a1 to be an ArrayList<String>, to which no Integer can be added.

Clearly, an ArrayList<?> is not very useful, as you can only insert null into it. That might be why the Java Spec forbids it:

It is a compile-time error if any of the type arguments used in a class instance creation expression are wildcard type arguments

ArrayList<ArrayList<?>> in contrast is a functional data type. You can add all kinds of ArrayLists into it, and retrieve them. And since ArrayList<?> only contains but is not a wildcard type, the above rule does not apply.

//Add "format" method to the string class
//supports:  "Welcome {0}. You are the first person named {0}".format("David");
//       and "First Name:{} Last name:{}".format("David","Wazy");
//       and "Value:{} size:{0} shape:{1} weight:{}".format(value, size, shape, weight)
String.prototype.format = function () {
    var content = this;
    for (var i = 0; i < arguments.length; i++) {
        var target = '{' + i + '}';
        content=content.split(target).join(String(arguments[i]))
        content = content.replace("{}", String(arguments[i]));
    }
    return content;
}
alert("I {} this is what {2} want and {} works for {2}!".format("hope","it","you"))

You can mix and match using positional and "named" replacement locations using this function.

The best option is create a directive and wrap the slider features there. The secret is use $timeout, the jquery code will be called only when DOM is ready.

angular.module('app')
.directive('my-slider', 
    ['$timeout', function($timeout) {
        return {
            restrict:'E',
            scope: true,
            template: '<div id="{{ id }}"></div>',
            link: function($scope) {
                $scope.id = String(Math.random()).substr(2, 8);

                $timeout(function() {
                    angular.element('#'+$scope.id).slider();                    
                });
            }
        };
    }]
);

But what if the element's CSS is like the following?

.element{
    position: absolute;left:-9999;    
}

So this answer to Stack Overflow question How to check if an element is off-screen should also be considered.

Another way to accomplish this in a pure PowerShell way would be to do something like this:

("" -eq ("{0}" -f $val).Trim())

This evaluates successfully for null, empty string, and whitespace. I'm formatting the passed value into an empty string to handle null (otherwise a null will cause an error when the Trim is called). Then just evaluate equality with an empty string. I think I still prefer the IsNullOrWhiteSpace, but if you're looking for another way to do it, this will work.

$val = null    
("" -eq ("{0}" -f $val).Trim())
>True
$val = "      "
("" -eq ("{0}" -f $val).Trim())
>True
$val = ""
("" -eq ("{0}" -f $val).Trim())
>True
$val = "not null or empty or whitespace"
("" -eq ("{0}" -f $val).Trim())
>False

In a fit of boredom, I played with this some and made it shorter (albeit more cryptic):

!!(("$val").Trim())

or

!(("$val").Trim())

depending on what you're trying to do.

Android Jetpack introduced WorkManager,which fixes the problem of background service restriction in Oreo and use of Alarm Manager below Lolipop and JobScheduler above Lolipop.

Please use WorkManager to run tasks on background thread and it's continue to run even after user closes the app.

This is how I handle this case:

On the machine where I have access to Internet:

mkdir keystone-deps
pip download python-keystoneclient -d "/home/aviuser/keystone-deps"
tar cvfz keystone-deps.tgz keystone-deps

Then move the tar file to the destination machine that does not have Internet access and perform the following:

tar xvfz keystone-deps.tgz
cd keystone-deps
pip install python_keystoneclient-2.3.1-py2.py3-none-any.whl -f ./ --no-index

You may need to add --no-deps to the command as follows:

pip install python_keystoneclient-2.3.1-py2.py3-none-any.whl -f ./ --no-index --no-deps

If someone wants to add a legend and/or colors to some vertical lines, then use this:

import matplotlib.pyplot as plt

# x coordinates for the lines
xcoords = [0.1, 0.3, 0.5]
# colors for the lines
colors = ['r','k','b']

for xc,c in zip(xcoords,colors):
    plt.axvline(x=xc, label='line at x = {}'.format(xc), c=c)

plt.legend()
plt.show()

Hey, this might not be the most ideal solution, but it works for me. I ended up creating a Python-Markdown LaTeX extension.

https://github.com/justinvh/Markdown-LaTeX

It adds support for inline math and text expressions using a $math$ and %text% syntax. The extension is a preprocessor that will use latex/dvipng to generate pngs for the respective equations/text and then base64 encode the data to inline the images directly, rather than have external images.

The data is then put in a simple-delimited cache file that encodes the expression to the base64 representation. This limits the number of times latex actually has to be run.

Here is an example:

%Hello, world!% This is regular text, but this: $y = mx + b$ is not.

The output:

$ markdown -x latex test.markdown
<p><img class='latex-inline math-false' alt='Hello, world!' id='Helloworld' src='data:image/png;base64,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'> This is regular text, but this: <img class='latex-inline math-true' alt='y = mx + b' id='ymxb' src='data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAFIAAAAOBAMAAABOTlYkAAAAMFBMVEX///9ERETu7u4yMjK6urp2dnZUVFSIiIjMzMwQEBDc3NwiIiJmZmaYmJiqqqoAAADS00rKAAAAAXRSTlMAQObYZgAAAOtJREFUKM9jYCAACsCk4wYGgiABTLInEKuS+QGxKvkVGBj47jBwI8tcffI84e45BoZ7GVcLECo9751iWLeSoRPITBQEggMMDBy9sxj2MDgz8DIE8yCpPMxwjWFBGUMMkpFcbAEMvxjKGLgYxIE8NkHBiYIyQMY+hmoGhi0Mdsi2czawbGCQBTJ+ILvzE0MaA9MHIIWwnWE9A+sBpk8LGDgmMCnAVXJNYPgCJHhRQvUiA/cDXoECZx4DXoSZTBtYgaaEPw5AVnkOGBRc5xTcbsReQrL9+nWwyxbgC88DcJZ+QygDcYD1+QPiFAIAtLA8KPZOGFEAAAAASUVORK5CYII='> is not.</p>

Identity = Name with Location

Every URL(Uniform Resource Locator) is a URI(Uniform Resource Identifier), abstractly speaking, but every URI is not a URL. There is another subcategory of URI is URN (Uniform Resource Name), which is a named resource but do not specify how to locate them, like mailto, news, ISBN is URIs. Source

URN:

• URN Format : urn:[namespace identifier]:[namespace specific string]
• urn: and : stand for themselves.
• Examples:
  • urn:uuid:6e8bc430-9c3a-11d9-9669-0800200c9a66
  • urn:ISSN:0167-6423
  • urn:isbn:096139210x
  • Amazon Resource Names (ARNs) is a uniquely identify AWS resources.
    • ARN Format : arn:partition:service:region:account-id:resource

URL:

• URL Format : [scheme]://[Domain][Port]/[path]?[queryString]#[fragmentId]
• :,//,? and # stand for themselves.
• schemes are https,ftp,gopher,mailto,news,telnet,file,man,info,whatis,ldap...
• Examples:
  • http://ip_server/path?query
  • ftp://ip_server/path
  • mailto:email-address
  • news:newsgroup-name
  • telnet://ip_server/
  • file://ip_server/path_segments
  • ldap://hostport/dn?attributes?scope?filter?extensions

Analogy:
To reach a person: Driving(protocol others SMS, email, phone), Address(hostname other phone-number, emailid) and person name(object name with a relative path).

The awk solution is what I would use, but if you want to understand your problems with bash, here is a revised version of your script.

#!/bin/bash -vx

##config file with ip addresses like 10.10.10.1:80
file=config.txt

while read line ; do
  ##this line is not correct, should strip :port and store to ip var
  ip=$( echo "$line" |cut -d\: -f1 )
  ping $ip
done < ${file}

You could write your top line as

for line in $(cat $file) ; do ...

(but not recommended).

You needed command substitution $( ... ) to get the value assigned to $ip

reading lines from a file is usually considered more efficient with the while read line ... done < ${file} pattern.

I hope this helps.

It matches p elements with class some_class that are directly under a div.

Retrofit 2.0 solution

@Multipart
@POST(APIUtils.UPDATE_PROFILE_IMAGE_URL)
public Call<CommonResponse> requestUpdateImage(@PartMap Map<String, RequestBody> map);

and

    Map<String, RequestBody> params = new HashMap<>();

    params.put("newProfilePicture" + "\"; filename=\"" + FilenameUtils.getName(file.getAbsolutePath()), RequestBody.create(MediaType.parse("image/jpg"), file));



 Call<CommonResponse> call = request.requestUpdateImage(params);

you can use
image/jpg image/png image/gif

No matter how many times you call Class.forName() method, Only once the static block gets executed not multiple time:

package forNameMethodDemo;

public class MainClass {

    public static void main(String[] args) throws Exception {
        Class.forName("forNameMethodDemo.DemoClass");
        Class.forName("forNameMethodDemo.DemoClass");
        Class.forName("forNameMethodDemo.DemoClass");
        DemoClass demoClass = (DemoClass)Class.forName("forNameMethodDemo.DemoClass").newInstance();
    }
}


public class DemoClass {
    
    static {
        System.out.println("in Static block");
    }

    {
        System.out.println("in Instance block");
    }
}

output will be:

in Static block
in Instance block

This in Static block statement is printed only once not three times.

In one reusable piece of code I use the directive <%@include file="reuse.html"%> and in the second I use the standard action <jsp:include page="reuse.html" />.

Let the code in the reusable file be:

<html>
<head>
    <title>reusable</title>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
</head>
<body>
    <img src="candle.gif" height="100" width="50"/> <br />
    <p><b>As the candle burns,so do I</b></p>
</body>

After running both the JSP files you see the same output and think if there was any difference between the directive and the action tag. But if you look at the generated servlet of the two JSP files, you will see the difference.

Here is what you will see when you use the directive:

out.write("<html>\r\n");
out.write("    <head>\r\n");
out.write("        <title>reusable</title>\r\n");
out.write("        <meta http-equiv=\"Content-Type\" content=\"text/html; charset=UTF-8\">\r\n");
out.write("    </head>\r\n");
out.write("    <body>\r\n");
out.write("        <img src=\"candle.gif\" height=\"100\" width=\"50\"/> <br />\r\n");
out.write("        <p><b>As the candle burns,so do I</b></p>\r\n");
out.write("    </body>\r\n");
out.write("</html>\r\n");
 

And this is what you will see for the used standard action in the second JSP file :

org.apache.jasper.runtime.JspRuntimeLibrary.include(request, response, "reusable.html", out, false);

So now you know that the include directive inserts the source of reuse.html at translation time, but the action tag inserts the response of reuse.html at runtime.

If you think about it, there is an extra performance hit with every action tag (<jsp:include>). It means you can guarantee you will always have the latest content, but it increases performance cost.

Transition is more like an animation.

div.sicon a {
    background:-moz-radial-gradient(left, #ffffff 24%, #cba334 88%);
    transition: background 0.5s linear;
    -moz-transition: background 0.5s linear; /* Firefox 4 */
    -webkit-transition: background 0.5s linear; /* Safari and Chrome */
    -o-transition: background 0.5s linear; /* Opera */
    -ms-transition: background 0.5s linear; /* Explorer 10 */
}

So you need to invoke that animation with an action.

div.sicon a:hover {
    background:-moz-radial-gradient(left, #cba334 24%, #ffffff 88%);
}

Also check for browser support and if you still have some problem with whatever you're trying to do! Check css-overrides in your stylesheet and also check out for behavior: ***.htc css hacks.. there may be something overriding your transition!

You should check this out: http://www.w3schools.com/css/css3_transitions.asp

Simply add the disabled class to the button instead of the disabled attribute to make it visibly disabled instead.

<button class="btn disabled" rel="tooltip" data-title="Dieser Link führt zu Google">button disabled</button>

Note: this button only appears to be disabled, but it still triggers events, and you just have to be mindful of that.

My team use Gradle and Nexus OSS 3.5.2,

I have found a solution: upload artyfacts from locakhost (I checked Nexus documentation and did not found anything about uploading artifacts from folders) => I have shared directory (use Apache httpd) and connected one to created new Nexus proxy repository. Now when I want to add my own artifacts I can upload ones into shared directory in my remote server.

Maybe someone find my solution useful:

My question is here: Is it possible to deploy artifacts from local folder in Sonatype Nexus Repository Manager 3.x

If the C variant needs x hours less, then I'd invest that time in letting the algorithms run longer/again

"invest" isn't the right word here.

1. Build a working implementation in Python. You'll finish this long before you'd finish a C version.

2. Measure performance with the Python profiler. Fix any problems you find. Change data structures and algorithms as necessary to really do this properly. You'll finish this long before you finish the first version in C.

3. If it's still too slow, manually translate the well-designed and carefully constructed Python into C.

   Because of the way hindsight works, doing the second version from existing Python (with existing unit tests, and with existing profiling data) will still be faster than trying to do the C code from scratch.

This quote is important.

It depends on how you tested it, and possibly on differences in the TCP stack implementation of the personal computer and the server.

For example, if your sendall always completes immediately (or very quickly) on the personal computer, the connection may simply never have broken during sending. This is very likely if your browser is running on the same machine (since there is no real network latency).

In general, you just need to handle the case where a client disconnects before you're finished, by handling the exception.

Remember that TCP communications are asynchronous, but this is much more obvious on physically remote connections than on local ones, so conditions like this can be hard to reproduce on a local workstation. Specifically, loopback connections on a single machine are often almost synchronous.

As simple as you can use const adults = family.filter(({ age }) => age > 18 );

const family =[{"name":"Jack",  "age": 26},_x000D_
              {"name":"Jill",  "age": 22},_x000D_
              {"name":"James", "age": 5 },_x000D_
              {"name":"Jenny", "age": 2 }];_x000D_

const adults = family.filter(({ age }) => age > 18 );_x000D_

This phrase is almost certainly an analogy with a phase in house construction — "stubbing out" plumbing. During construction, while the walls are still open, the rough plumbing is put in. This is necessary for the construction to continue. Then, when everything around it is ready enough, one comes back and adds faucets and toilets and the actual end-product stuff. (See for example How to Install a Plumbing Stub-Out.)

When you "stub out" a function in programming, you build enough of it to work around (for testing or for writing other code). Then, you come back later and replace it with the full implementation.

Just in case you want to see all of the gory details in human readable form, you can use:

import platform;

print(platform.sys.version);

Output for my system:

3.6.5 |Anaconda, Inc.| (default, Apr 29 2018, 16:14:56) 
[GCC 7.2.0]

Something very detailed but machine parsable would be to get the version_info object from platform.sys, instead, and then use its properties to take a predetermined course of action. For example:

import platform;

print(platform.sys.version_info)

Output on my system:

sys.version_info(major=3, minor=6, micro=5, releaselevel='final', serial=0)

Use below code for IMEI:

TelephonyManager tm = (TelephonyManager)getSystemService(TELEPHONY_SERVICE);
String imei= tm.getDeviceId();

go to Run Configuration and in argument tab you can write your argument

As per latest api docs:

$(document).ready(function() {
    $('#example').dataTable({
        "order": []
    });
});

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

Solution for me:

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

run on terminal

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

Create a new pair of SSH keys

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

Copy content of public key

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

On other shell in Homestead VM Machine copy into authorized_keys

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

Now can access with vagrant ssh

The dropdown width itself cannot be set. It's width depend on the option-values. See also here ( jsfiddle.net/LgS3C/ )

How the select box looks like is also depending on your browser.

You can build your own control or use Select2 https://select2.org

This is just a sample code, but it may help you get on your way:

Public Sub testIt()
    Workbooks("Workbook2").Activate
    ActiveWorkbook.Sheets("Sheet2").Activate
    ActiveSheet.Range("B3").Select
    ActiveCell.EntireRow.Insert
End Sub

I am assuming that you can open the book (called Workbook2 in the example).

I think (but I'm not sure) you can squash all this in a single line of code:

    Workbooks("Workbook2").Sheets("Sheet2").Range("B3").EntireRow.Insert

This way you won't need to activate the workbook (or sheet or cell)... Obviously, the book has to be open.

Use Redis if

1. You require selectively deleting/expiring items in the cache. (You need this)

2. You require the ability to query keys of a particular type. eq. 'blog1:posts:*', 'blog2:categories:xyz:posts:*'. oh yeah! this is very important. Use this to invalidate certain types of cached items selectively. You can also use this to invalidate fragment cache, page cache, only AR objects of a given type, etc.

3. Persistence (You will need this too, unless you are okay with your cache having to warm up after every restart. Very essential for objects that seldom change)

Use memcached if

1. Memcached gives you headached!
2. umm... clustering? meh. if you gonna go that far, use Varnish and Redis for caching fragments and AR Objects.

From my experience I've had much better stability with Redis than Memcached

REV=svn info svn://svn.code.sf.net/p/retroshare/code/trunk | grep 'Revision:' | cut -d\ -f2

In plain-old JavaScript you can do this:

var inputs = document.getElementsByTagName('input');

for(var i = 0; i < inputs.length; i++) {
    if(inputs[i].type.toLowerCase() == 'text') {
        alert(inputs[i].value);
    }
}

In jQuery, you would just do:

// select all inputs of type 'text' on the page
$("input:text")

// hide all text inputs which are descendants of div class="foo"
$("div.foo input:text").hide();

eldNew <- eld[-14,]

See ?"[" for a start ...

For ‘[’-indexing only: ‘i’, ‘j’, ‘...’ can be logical vectors, indicating elements/slices to select. Such vectors are recycled if necessary to match the corresponding extent. ‘i’, ‘j’, ‘...’ can also be negative integers, indicating elements/slices to leave out of the selection.

(emphasis added)

The --force option will reinstall already installed packages or overwrite already installed files from other packages. You don't want this normally.

If you tell rpm to install all RPMs from some directory, then it does exactly this. rpm will not ignore RPMs listed for installation. You must manually remove the unneeded RPMs from the list (or directory). It will always overwrite the files with the "latest RPM installed" whichever order you do it in.

You can remove the old RPM and rpm will resolve the dependency with the newer version of the installed RPM. But this will only work, if none of the to be installed RPMs depends exactly on the old version.

If you really need different versions of the same RPM, then the RPM must be relocatable. You can then tell rpm to install the specific RPM to a different directory. If the files are not conflicting, then you can just install different versions with rpm -i (zypper in can not install different versions of the same RPM). I am packaging for example ruby gems as relocatable RPMs at work. So I can have different versions of the same gem installed.

I don't know on which files your RPMs are conflicting, but if all of them are "just" man pages, then you probably can simply overwrite the new ones with the old ones with rpm -i --replacefiles. The only problem with this would be, that it could confuse somebody who is reading the old man page and thinks it is for the actual version. Another problem would be the rpm --verify command. It will complain for the new package if the old one has overwritten some files.

Is this possibly a duplicate of https://serverfault.com/questions/522525/rpm-ignore-conflicts?

Despite following the accepted answer exactly, I was still unable to get the service to start-- I was instead given a failure message during installation stating that the service that was just installed could not be started, as it did not exist, despite using this.serviceInstaller.ServiceName rather than a literal...

I eventually found an alternative solution that makes use of the command line:

private void serviceInstaller_AfterInstall(object sender, InstallEventArgs e) {
        ProcessStartInfo startInfo = new ProcessStartInfo();
        startInfo.WindowStyle = ProcessWindowStyle.Hidden;
        startInfo.FileName = "cmd.exe";
        startInfo.Arguments = "/C sc start " + this.serviceInstaller.ServiceName;

        Process process = new Process();
        process.StartInfo = startInfo;
        process.Start();
    }

The simplest way to add x no. of days..

echo date('Y-m-d',strtotime('+1 day'));    //+1 day from today

OR from specified date...

echo date('Y-m-d',strtotime('+1 day', strtotime('2007-02-28')));

The easiest is:

Step 1. Install "Apache_OpenOffice_4.1.2" in your system Step 2. Download "unoconv" library from github or any where else.

-> C:\Program Files (x86)\OpenOffice 4\program\python.exe = Path of open office install directory

-> D:\wamp\www\doc_to_pdf\libobasis4.4-pyuno\unoconv = Path of library folder

-> D:/wamp/www/doc_to_pdf/files/'.$pdf_File_name.' = path and file name of pdf

-> D:/wamp/www/doc_to_pdf/files/'.$doc_file_name = Path of your document file.

If pdf not created than last step is Go to ->Control Panel\All Control Panel Items\Administrative Tools-> services-> find "wampapache" -> right click and click on property -> click on logon tab Than check checkbox of allow service to interact with desktop

Create sample .php file and put below code and run on wamp or xampp server

$result = exec('"C:\Program Files (x86)\OpenOffice 4\program\python.exe" D:\wamp\www\doc_to_pdf\libobasis4.4-pyuno\unoconv -f pdf -o D:/wamp/www/doc_to_pdf/files/'.$pdf_File_name.' D:/wamp/www/doc_to_pdf/files/'.$doc_file_name);

This code working for me in windows-8 operating system

I was executing a get request an also want to see just the response and nothing else, seems like magic is done with -silent,-s option.

From the curl man page:

-s, --silent Silent or quiet mode. Don't show progress meter or error messages. Makes Curl mute. It will still output the data you ask for, potentially even to the terminal/stdout unless you redirect it.

Below the examples:

curl -s "http://host:8080/some/resource"
curl -silent "http://host:8080/some/resource"

Using custom headers

curl -s -H "Accept: application/json" "http://host:8080/some/resource")

Using POST method with a header

curl -s -X POST -H "Content-Type: application/json" "http://host:8080/some/resource") -d '{ "myBean": {"property": "value"}}'

You can also customize the output for specific values with -w, below the options I use to get just response codes of the curl:

curl -s -o /dev/null -w "%{http_code}" "http://host:8080/some/resource"

If you are using Sql Server Management Studio, you can obtain a list of all schemas, create your own schema or remove an existing one by browsing to:

Databases - [Your Database] - Security - Schemas

[

You can do (pre-Java 8):

List<Enum> enumValues = Arrays.asList(Enum.values());

or

List<Enum> enumValues = new ArrayList<Enum>(EnumSet.allOf(Enum.class));

Using Java 8 features, you can map each constant to its name:

List<String> enumNames = Stream.of(Enum.values())
                               .map(Enum::name)
                               .collect(Collectors.toList());

I'm guessing EventDate is a char or varchar and not a date otherwise your order by clause would be fine.

You can use CONVERT to change the values to a date and sort by that

SELECT * 
FROM 
     vw_view 
ORDER BY 
   CONVERT(DateTime, EventDate,101)  DESC

The problem with that is, as Sparky points out in the comments, if EventDate has a value that can't be converted to a date the query won't execute.

This means you should either exclude the bad rows or let the bad rows go to the bottom of the results

To exclude the bad rows just add WHERE IsDate(EventDate) = 1

To let let the bad dates go to the bottom you need to use CASE

e.g.

ORDER BY 
    CASE
       WHEN IsDate(EventDate) = 1 THEN CONVERT(DateTime, EventDate,101)
       ELSE null
    END DESC

Change IDs and data attributes as you wish!

  <select id="selectVehicle">
       <option value="1" data-year="2011">Mazda</option>
       <option value="2" data-year="2015">Honda</option>
       <option value="3" data-year="2008">Mercedes</option>
       <option value="4" data-year="2005">Toyota</option>
  </select>

$("#selectVehicle").change(function () {
     alert($(this).find(':selected').data("year"));
});

Here is the working example: https://jsfiddle.net/ed5axgvk/1/

During the preflight request, you should see the following two headers: Access-Control-Request-Method and Access-Control-Request-Headers. These request headers are asking the server for permissions to make the actual request. Your preflight response needs to acknowledge these headers in order for the actual request to work.

For example, suppose the browser makes a request with the following headers:

Origin: http://yourdomain.com
Access-Control-Request-Method: POST
Access-Control-Request-Headers: X-Custom-Header

Your server should then respond with the following headers:

Access-Control-Allow-Origin: http://yourdomain.com
Access-Control-Allow-Methods: GET, POST
Access-Control-Allow-Headers: X-Custom-Header

Pay special attention to the Access-Control-Allow-Headers response header. The value of this header should be the same headers in the Access-Control-Request-Headers request header, and it can not be '*'.

Once you send this response to the preflight request, the browser will make the actual request. You can learn more about CORS here: http://www.html5rocks.com/en/tutorials/cors/

Using a single Awk:

... | awk -F '[/:]' '{print $5}'

That is, using as field separator either / or :, the username is always in field 5.

To store it in a variable:

username=$(... | awk -F '[/:]' '{print $5}')

A more flexible implementation with sed that doesn't require username to be field 5:

... | sed -e s/:.*// -e s?.*/??

That is, delete everything from : and beyond, and then delete everything up until the last /. sed is probably faster too than awk, so this alternative is definitely better.

Use this method:

private Long secondsBetween(Date first, Date second){
    return (second.getTime() - first.getTime())/1000;
}
