The following code worked for me:

echo userInput

writexl, without Java requirement:

# install.packages("writexl")
library(writexl)
tempfile <- write_xlsx(iris)

No. You can't send headers after they were sent. Try to use hooks in wordpress

I wrote the following code to convert an image from sdcard to a Base64 encoded string to send as a JSON object.And it works great:

String filepath = "/sdcard/temp.png";
File imagefile = new File(filepath);
FileInputStream fis = null;
try {
    fis = new FileInputStream(imagefile);
    } catch (FileNotFoundException e) {
    e.printStackTrace();
}

Bitmap bm = BitmapFactory.decodeStream(fis);
ByteArrayOutputStream baos = new ByteArrayOutputStream();  
bm.compress(Bitmap.CompressFormat.JPEG, 100 , baos);    
byte[] b = baos.toByteArray(); 
encImage = Base64.encodeToString(b, Base64.DEFAULT);

Do this:

$(document).ready(function(){
    $(".header").click(function(){
        $(this).children(".children").toggle();
    });
   $(".header a").click(function(e) {
        e.stopPropagation();
   });
});

(tomcat 7.0.32) I had problems to see debug messages althought was enabling TldLocationsCache row in tomcat/conf/logging.properties file. All I could see was a warning but not what libs were scanned. Changed every loglevel tried everything no luck. Then I went rogue debug mode (=remove one by one, clean install etc..) and finally found a reason.

My webapp had a customized tomcat/webapps/mywebapp/WEB-INF/classes/logging.properties file. I copied TldLocationsCache row to this file, finally I could see jars filenames.

# To see debug messages in TldLocationsCache, uncomment the following line: org.apache.jasper.compiler.TldLocationsCache.level = FINE

Managed to get answer after do some google..

As stated in the answer by Henrik, titles are left-aligned by default starting with ggplot 2.2.0. Titles can be centered by adding this to the plot:

theme(plot.title = element_text(hjust = 0.5))

However, if you create many plots, it may be tedious to add this line everywhere. One could then also change the default behaviour of ggplot with

theme_update(plot.title = element_text(hjust = 0.5))

Once you have run this line, all plots created afterwards will use the theme setting plot.title = element_text(hjust = 0.5) as their default:

theme_update(plot.title = element_text(hjust = 0.5))
ggplot() + ggtitle("Default is now set to centered")

To get back to the original ggplot2 default settings you can either restart the R session or choose the default theme with

theme_set(theme_gray())

Just in case anyone will search for it - I used it on several sites, always the customization and RD possibilities were a perfect fit for what I needed. Simple and it is free to use:

Clickable CSS Maps

One note for more scripts on a site: I had some annoying problems with getting to work a map (that worked as a graphic menu) in Drupal 7. There where many other script used, and after handling them, I got stuck with the map - it still didn't work, although the jquery.cssmap.js, CSS (both local) and the script in the where in the right place. Firebug showed me an error and I suddenly eureka - a simple oversight, I left the script code as it was in the example and there was a conflict. Just change the front function "$" to "jQuery" (or other handler) and it works perfect. :]

Here's what I ment (of course you can put it before instead of the ):

<script type="text/javascript">_x000D_
      jQuery(function($){_x000D_
        $('#map-country').cssMap({'size' : 810});_x000D_
       });_x000D_
    </script>

The resources you put in src/main/resources will be copied during the build process to target/classes which can be accessed using:

...this.getClass().getResourceAsStream("/config.txt");

Many changes you can make very easily and visually in the table editor in SQL Server Management Studio actually require SSMS to drop the table in the background and re-create it from scratch. Even simple things like reordering the columns cannot be expressed in standard SQL DDL statement - all SSMS can do is drop and recreate the table.

This operation can be a) very time consuming on a large table, or b) might even fail for various reasons (like FK constraints and stuff). Therefore, SSMS in SQL Server 2008 introduced that new option the other answers have already identified.

It might seem counter-intuitive at first to prevent such changes - and it's certainly a nuisance on a dev server. But on a production server, this option and its default value of preventing such changes becomes a potential life-saver!

Your question is mixing a few different concepts. You started out saying you wanted to run sites on the same server using the same domain, but in different folders. That doesn't require any special setup. Once you get the single domain running, you just create folders under that docroot.

Based on the rest of your question, what you really want to do is run various sites on the same server with their own domain names.

The best documentation you'll find on the topic is the virtual host documentation in the apache manual.

There are two types of virtual hosts: name-based and IP-based. Name-based allows you to use a single IP address, while IP-based requires a different IP for each site. Based on your description above, you want to use name-based virtual hosts.

The initial error you were getting was due to the fact that you were using different ports than the NameVirtualHost line. If you really want to have sites served from ports other than 80, you'll need to have a NameVirtualHost entry for each port.

Assuming you're starting from scratch, this is much simpler than it may seem.

If you are using 2.3 or earlier, the first thing you need to do is tell Apache that you're going to use name-based virtual hosts.

NameVirtualHost *:80

If you are using 2.4 or later do not add a NameVirtualHost line. Version 2.4 of Apache deprecated the NameVirtualHost directive, and it will be removed in a future version.

Now your vhost definitions:

<VirtualHost *:80>
    DocumentRoot "/home/user/site1/"
    ServerName site1
</VirtualHost>

<VirtualHost *:80>
    DocumentRoot "/home/user/site2/"
    ServerName site2
</VirtualHost>

You can run as many sites as you want on the same port. The ServerName being different is enough to tell Apache which vhost to use. Also, the ServerName directive is always the domain/hostname and should never include a path.

If you decide to run sites on a port other than 80, you'll always have to include the port number in the URL when accessing the site. So instead of going to http://example.com you would have to go to http://example.com:81

While the w32tm /resync in theory does the job, it only does so under certain conditions. When "down to the millisecond" matters, however, I found that Windows wouldn't actually make the adjustment; as if "oh, I'm off by 2.5 seconds, close enough bro, nothing to see or do here".

In order to truly force the resync (Windows 7):

1. Control Panel -> Date and Time
2. "Change date and time..." (requires Admin privileges)
3. Add or Subtract a few minutes (I used -5 minutes)
4. Run "cmd.exe" as administrator
5. w32tm /resync
6. Visually check that the seconds in the "Date and Time" control panel are ticking at the same time as your authoritative clock(s). (I used watch -n 0.1 date on a Linux machine on the network that I had SSH'd over into)

--- Rapid Method ---

1. Run "cmd.exe" as administrator
2. net start w32time (Time Service must be running)
3. time 8 (where 8 may be replaced by any 'hour' value, presumably 0-23)
4. w32tm /resync
5. Jump to 3, as needed.

One reason for using non-standard checkbox serialization that isn't addressed in the question or in of the current answers is to only deserialize (change) fields that were explicitly specified in the serialized data - e.g. when you are using jquery serialization and deserialization to/from a cookie to save and load prefererences.

Thomas Danemar implemented a modification to the standard serialize() method to optionally take a checkboxesAsBools option: http://tdanemar.wordpress.com/2010/08/24/jquery-serialize-method-and-checkboxes/ - this is similar to the implementation listed above by @mydoghasworms, but also integrated into the standard serialize.

I've copied it to Github in case anyone has improvements to make at any point: https://gist.github.com/1572512

Additionally, the "jquery.deserialize" plugin will now correctly deserialize checkbox values serialized with checkboxesAsBools, and ignore checkboxes that are not mentioned in the serialized data: https://github.com/itsadok/jquery.deserialize

To iterate a loop a fixed number of times, try:

n.times do
  #Something to be done n times
end

Try this:

var data = [{field:"Data",type:"date"},  {field:"Numero",type:"number"}];

var columns = {};

var index = 0;

$.each(data, function() {

    columns[index] = {
        field : this.field,
        type : this.type
    };

    index++;
});

console.log(columns);

Typing n will go to the next match.

Put this code in your .htaccess file

RewriteEngine On
ErrorDocument 404 /404.php

where 404.php is the file name and placed at root. You can put full path over here.

To "call" means to make a reference in your code to a function that is written elsewhere. This function "call" can be made to the standard Python library (stuff that comes installed with Python), third-party libraries (stuff other people wrote that you want to use), or your own code (stuff you wrote). For example:

#!/usr/env python

import os

def foo():
    return "hello world"

print os.getlogin()
print foo()

I created a function called "foo" and called it later on with that print statement. I imported the standard "os" Python library then I called the "getlogin" function within that library.

You could try to find the indexOf "o1 " first. Then extract it. After this, Split the string using the chars "1232.5467":

        string test = "o1 1232.5467 1232.5467 1232.5467 1232.5467 1232.5467 1232.5467";
        string header = test.Substring(test.IndexOf("o1 "), "o1 ".Length);
        test = test.Substring("o1 ".Length, test.Length - "o1 ".Length);
        string[] content = test.Split(' ');

You'll have to do 2 things to make a Bootstrap label (or anything really) adjust sizes based on screen size:

• Use a media query per display size range to adjust the CSS.
• Override CSS sizing set by Bootstrap. You do this by making your CSS rules more specific than Bootstrap's. By default, Bootstrap sets .label { font-size: 75% }. So any extra selector on your CSS rule will make it more specific.

Here's an example CSS listing to accomplish what you are asking, using the default 4 sizes in Bootstrap:

@media (max-width: 767) {
    /* your custom css class on a parent will increase specificity */
    /* so this rule will override Bootstrap's font size setting */
    .autosized .label { font-size: 14px; }
}

@media (min-width: 768px) and (max-width: 991px) {
    .autosized .label { font-size: 16px; }
}

@media (min-width: 992px) and (max-width: 1199px) {
    .autosized .label { font-size: 18px; }
}

@media (min-width: 1200px) {
    .autosized .label { font-size: 20px; }
}

Here is how it could be used in the HTML:

<!-- any ancestor could be set to autosized -->
<div class="autosized">
    ...
        ...
            <span class="label label-primary">Label 1</span>
</div>

It's 2017 and it IS possible to target specific select options. In my project I have a table with a class="variations", and the select options are in the table cell td="value", and the select has an ID select#pa_color. The option element also has a class option="attached" (among other class tags). If a user is logged in as a wholesale customer, they can see all of the color options. But retail customers are not allowed to purchase 2 color options, so I've disabled them

<option class="attached" disabled>color 1</option>
<option class="attached" disabled>color 2</option>

It took a little logic, but here is how I targeted the disabled select options.

CSS

table.variations td.value select#pa_color option.attached:disabled {
display: none !important;
}

With that, my color options are only visible to wholesale customers.

select *
from YourTable
where ','+replace(col, ' ', '')+',' like '%,Cat,%'

Here's a solution that also works on Firefox:

transition: all 0.3s ease, background-position 1ms;

I made a small demo: http://jsfiddle.net/aWzwh/

OR, even better just the ol' "drag and drop" the folder, onto your repository opened in git browser.

1. Open your repository in the web portal , you will see the listing of all your files. If you have just recently created the repo, and initiated with a README, you will only see the README listing.

2. Open your folder which you want to upload. drag and drop on the listing in browser. See the image here.

I have put together a collection of categories for NSData and NSString which uses solutions found on Jeff LaMarche's blog and some hints by Quinn Taylor here on Stack Overflow.

It uses categories to extend NSData to provide AES256 encryption and also offers an extension of NSString to BASE64-encode encrypted data safely to strings.

Here's an example to show the usage for encrypting strings:

NSString *plainString = @"This string will be encrypted";
NSString *key = @"YourEncryptionKey"; // should be provided by a user

NSLog( @"Original String: %@", plainString );

NSString *encryptedString = [plainString AES256EncryptWithKey:key];
NSLog( @"Encrypted String: %@", encryptedString );

NSLog( @"Decrypted String: %@", [encryptedString AES256DecryptWithKey:key] );

Try this How to move a full Git repository

1. Create a local repository in the temp-dir directory using:

   git clone temp-dir

2. Go into the temp-dir directory.

3. To see a list of the different branches in ORI do:

   git branch -a
   

4. Checkout all the branches that you want to copy from ORI to NEW using:

   git checkout branch-name
   

5. Now fetch all the tags from ORI using:

   git fetch --tags
   

6. Before doing the next step make sure to check your local tags and branches using the following commands:

   git tag
   
   
   git branch -a
   

7. Now clear the link to the ORI repository with the following command:

   git remote rm origin
   

8. Now link your local repository to your newly created NEW repository using the following command:

   git remote add origin <url to NEW repo>
   

9. Now push all your branches and tags with these commands:

   git push origin --all
   
   
   git push --tags
   

10. You now have a full copy from your ORI repo.

For raw files, you should consider creating a raw folder inside res directory and then call getResources().openRawResource(resourceName) from your activity.

To achieve this use following html:

<a href="www.mysite.com" onclick="make(event)">Item</a>

<script>
    function make(e) {
        // ...  your function code
        // e.preventDefault();   // use this to NOT go to href site
    }
</script>

Here is working example.

With EasyGui:

import easygui
print(easygui.fileopenbox())

To install:

pip install easygui

Demo:

import easygui
easygui.egdemo()

Are you trying to view an array with memory allocated dynamically? If not, you can view an array for C++ and C# by putting it in the watch window in the debugger, with its contents visible when you expand the array on the little (+) in the watch window by a left mouse-click.

If it's a pointer to a dynamically allocated array, to view N contents of the pointer, type "pointer, N" in the watch window of the debugger. Note, N must be an integer or the debugger will give you an error saying it can't access the contents. Then, left click on the little (+) icon that appears to view the contents.

I tried the various solutions provided here and they worked fine if you simply wanted a couple of drop downs.

The best (in appearance etc) 'picker' (https://github.com/thebrowser/jquery.ui.monthpicker) suggested here is basically a copy of an old version of jquery-ui datepicker with the _generateHTML rewritten. However, I found it no longer plays nicely with current jquery-ui (1.10.2) and had other issues (doesn't close on esc, doesn't close on other widget opening, has hardcoded styles).

Rather than attempt to fix that monthpicker and rather than reattempt the same process with the latest datepicker, I went with hooking into the relevant parts of the existing date picker.

This involves overriding:

• _generateHTML (to build the month picker markup)
• parseDate (as it doesn't like it when there's no day component),
• _selectDay (as datepicker uses .html() to get the day value)

As this question is a bit old and already well answered, here's only the _selectDay override to show how this was done:

jQuery.datepicker._base_parseDate = jQuery.datepicker._base_parseDate || jQuery.datepicker.parseDate;
jQuery.datepicker.parseDate = function (format, value, settings) {
    if (format != "M y") return jQuery.datepicker._hvnbase_parseDate(format, value, settings);
    // "M y" on parse gives error as doesn't have a day value, so 'hack' it by simply adding a day component
    return jQuery.datepicker._hvnbase_parseDate("d " + format, "1 " + value, settings);
};

As stated, this is an old question, but I found it useful so wanted to add feedback with an alterantive solution.

You can create a new table using the following code.

SELECT IDENTITY (int, 1, 1) AS id, column1, column2
INTO dbo.NewTable
FROM dbo.OldTable

Then delete the old db, and rename the new db to the old db's name. Note: that column1 and column2 represent all the columns in your old table that you want to keep in your new table.

• DTR - Data Terminal Ready
• DSR - Data Set Ready
• RTS - Request To Send
• CTS - Clear To Send

There are multiple ways of doing things because there were never any protocols built into the standards. You use whatever ad-hoc "standard" your equipment implements.

Just based on the names, RTS/CTS would seem to be a natural fit. However, it's backwards from the needs that developed over time. These signals were created at a time when a terminal would batch-send a screen full of data, but the receiver might not be ready, thus the need for flow control. Later the problem would be reversed, as the terminal couldn't keep up with data coming from the host, but the RTS/CTS signals go the wrong direction - the interface isn't orthogonal, and there's no corresponding signals going the other way. Equipment makers adapted as best they could, including using the DTR and DSR signals.

EDIT

To add a bit more detail, its a two level hierarchy so "officially" both must happen for communication to take place. The behavior is defined in the original CCITT (now ITU-T) standard V.28.

The DCE is a modem connecting between the terminal and telephone network. In the telephone network was another piece of equipment which split off to the data network, eg. X.25.

The modem has three states: Powered off, Ready (Data Set Ready is true), and connected (Data Carrier Detect)

The terminal can't do anything until the modem is connected.

When the modem wants to send data, it raises RTS and the modem grants the request with CTS. The modem lowers CTS when its internal buffer is full.

So nostalgic!

I had a similar problem where the SelectedItem-binding did not update when I selected something in the combobox. My problem was that I had to set UpdateSourceTrigger=PropertyChanged for the binding.

<ComboBox ItemsSource="{Binding SalesPeriods}" 
          SelectedItem="{Binding SelectedItem, UpdateSourceTrigger=PropertyChanged}" />

To avoid possible overlapping of execution, use a locking mechanism as described in that thread.

Here is a Github link to a lightweight and very easy to integrate library that enables you to play with borders as you want for any widget you want, simply based on a FrameLayout widget.

Here is a quick sample code for you to see how easy it is, but you will find more information on the link.

<com.khandelwal.library.view.BorderFrameLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            app:leftBorderColor="#00F0F0"
            app:leftBorderWidth="10dp"
            app:topBorderColor="#F0F000"
            app:topBorderWidth="15dp"
            app:rightBorderColor="#F000F0"
            app:rightBorderWidth="20dp"
            app:bottomBorderColor="#000000"
            app:bottomBorderWidth="25dp" >
    </com.khandelwal.library.view.BorderFrameLayout>

So, if you don't want borders on bottom, delete the two lines about bottom in this custom widget, and that's done.

And no, I'm neither the author of this library nor one of his friend ;-)

You cannot add AM / PM to a TimeSpan. You'll anyway have to associate the TimaSpan value with DateTime if you want to display the time in 12-hour clock format.

TimeSpan is not intended to use with a 12-hour clock format, because we are talking about a time interval here.

As it says in the documentation;

A TimeSpan object represents a time interval (duration of time or elapsed time) that is measured as a positive or negative number of days, hours, minutes, seconds, and fractions of a second. The TimeSpan structure can also be used to represent the time of day, but only if the time is unrelated to a particular date. Otherwise, the DateTime or DateTimeOffset structure should be used instead.

Also Microsoft Docs describes as follows;

A TimeSpan value can be represented as [-]d.hh:mm:ss.ff, where the optional minus sign indicates a negative time interval, the d component is days, hh is hours as measured on a 24-hour clock, mm is minutes, ss is seconds, and ff is fractions of a second.

So in this case, you can display using AM/PM as follows.

TimeSpan storedTime = new TimeSpan(03,00,00);
string displayValue = new DateTime().Add(storedTime).ToString("hh:mm tt");

Side note :
Also should note that the TimeOfDay property of DateTime is a TimeSpan, where it represents

a time interval that represents the fraction of the day that has elapsed since midnight.

R/Rscript doesn't have concrete datatypes.

R interpreter has a duck-typing memory allocation system. There is no builtin method to tell you the datatype of your pointer to memory. Duck typing is done for speed, but turned out to be a bad idea because now statements such as: print(is.integer(5)) returns FALSE and is.integer(as.integer(5)) returns TRUE. Go figure.

The R-manual on basic types: https://cran.r-project.org/doc/manuals/R-lang.html#Basic-types

The best you can hope for is to write your own function to probe your pointer to memory, then use process of elimination to decide if it is suitable for your needs.

If your variable is a global or an object:

Your object() needs to be penetrated with get(...) before you can see inside. Example:

a <- 10
myGlobals <- objects()
for(i in myGlobals){
  typeof(i)         #prints character
  typeof(get(i))    #prints integer
}

typeof(...) probes your variable pointer to memory:

The R function typeof has a bias to give you the type at maximum depth, for example.

library(tibble)

#expression              notes                                  type
#----------------------- -------------------------------------- ----------
typeof(TRUE)             #a single boolean:                     logical
typeof(1L)               #a single numeric with L postfixed:    integer
typeof("foobar")         #A single string in double quotes:     character
typeof(1)                #a single numeric:                     double
typeof(list(5,6,7))      #a list of numeric:                    list

class(...) probes your variable pointer to memory:

The R function class has a bias to give you the type of container or structure encapsulating your types, for example.

Get the data storage.mode of your variable:

When an R variable is written to disk, the data layout changes again, and is called the data's storage.mode. The function storage.mode(...) reveals this low level information: see Mode, Class, and Type of R objects. You shouldn't need to worry about R's storage.mode unless you are trying to understand delays caused by round trip casts/coercions that occur when assigning and reading data to and from disk.

Demo: R/Rscript gettype(your_variable):

Run this R code then adapt it for your purposes, it'll make a pretty good guess as to what type it is.

I put in a C++/Java/Python ideology here that gives me the scoop of what the memory most looks like. R triad typing system is like trying to nail spaghetti to the wall, <- and <<- will package your matrix to a list when you least suspect. As the old duck-typing saying goes: If it waddles like a duck and if it quacks like a duck and if it has feathers, then it's a duck.

dicts = {}
keys = range(4)
values = ["Hi", "I", "am", "John"]
for i in keys:
        dicts[i] = values[i]
print(dicts)

alternatively

In [7]: dict(list(enumerate(values)))
Out[7]: {0: 'Hi', 1: 'I', 2: 'am', 3: 'John'}

Ok, since my attempt to post my solution in a comment failed, here's what I was trying to say. I could do exactly what I wanted from native Python (on Windows, not anywhere else though) with the following code:

import msvcrt 

def kbfunc(): 
   x = msvcrt.kbhit()
   if x: 
      ret = ord(msvcrt.getch()) 
   else: 
      ret = 0 
   return ret

Try this:

net use * /delete /y

The /y key makes it select Yes in prompt silently

Besides using std::find (from algorithm), you can also use std::find_if (which is, IMO, better than std::find), or other find algorithm from this list

#include <list>
#include <algorithm>
#include <iostream>

int main()
{
    std::list<int> myList{ 5, 19, 34, 3, 33 };
    

    auto it = std::find_if( std::begin( myList ),
                            std::end( myList ),
                            [&]( const int v ){ return 0 == ( v % 17 ); } );
        
    if ( myList.end() == it )
    {
        std::cout << "item not found" << std::endl;
    }
    else
    {
        const int pos = std::distance( myList.begin(), it ) + 1;
        std::cout << "item divisible by 17 found at position " << pos << std::endl;
    }
}

I have used RxPY which has some nice threading functions to solve this in a fairly clean manner. No queues, and I have provided a function that runs on the main thread after completion of the background thread. Here is a working example:

import rx
from rx.scheduler import ThreadPoolScheduler
import time
import tkinter as tk

class UI:
   def __init__(self):
      self.root = tk.Tk()
      self.pool_scheduler = ThreadPoolScheduler(1) # thread pool with 1 worker thread
      self.button = tk.Button(text="Do Task", command=self.do_task).pack()

   def do_task(self):
      rx.empty().subscribe(
         on_completed=self.long_running_task, 
         scheduler=self.pool_scheduler
      )

   def long_running_task(self):
      # your long running task here... eg:
      time.sleep(3)
      # if you want a callback on the main thread:
      self.root.after(5, self.on_task_complete)

   def on_task_complete(self):
       pass # runs on main thread

if __name__ == "__main__":
    ui = UI()
    ui.root.mainloop()

Another way to use this construct which might be cleaner (depending on preference):

tk.Button(text="Do Task", command=self.button_clicked).pack()

...

def button_clicked(self):

   def do_task(_):
      time.sleep(3) # runs on background thread
             
   def on_task_done():
      pass # runs on main thread

   rx.just(1).subscribe(
      on_next=do_task, 
      on_completed=lambda: self.root.after(5, on_task_done), 
      scheduler=self.pool_scheduler
   )

As other posters have stated the issue here has to do with the JRE that eclipse is using not being able to find the tools jar. I solved the issue by going in a bit of a different direction than what was stated above, and it was because of the way that my projects and environment.

Eclipse 4.5 requires at least Java 7 for runtime, so I've got my system setup to use a Java 8 JRE located at C:\java\jre1.8.0_45.

Next, I'm using a POM file that assumes that I'm running with a Java 6 JDK.

  </dependencies>

I'm not allowed to change the POM file, so I had to do some jiggery pokery. I copied the tools.jar from my Java 6 JDK, created the directory C:\java\lib and pasted it there. I then restarted eclipse and cleaned my project. And VOILA errors are gone.

It's not an elegant solution, and I would think that the proper solution would be to change the way the POM is setup, but as I was not able to, this works.

This is the easiest way I have found to download multiple files.

$('body').on('click','.download_btn',function(){
    downloadFiles([
        ['File1.pdf', 'File1-link-here'],
        ['File2.pdf', 'File2-link-here'],
        ['File3.pdf', 'File3-link-here'],
        ['File4.pdf', 'File4-link-here']
    ]);
})
function downloadFiles(files){
    if(files.length == 0){
        return;
    }
    file = files.pop();
    var Link = $('body').append('<a href="'+file[1]+'" download="file[0]"></a>');
    Link[0].click(); 
    Link.remove();
    downloadFiles(files);
}

This should be work for you. Thank You.

Very late answer, but I think my answer is more straight forward for specific use cases where users want to simply insert (copy) data from table A into table B:

INSERT INTO table_b (col1, col2, col3, col4, col5, col6)
SELECT col1, 'str_val', int_val, col4, col5, col6
FROM table_a

ValueError: cannot convert float NaN to integer

From v0.24, you actually can. Pandas introduces Nullable Integer Data Types which allows integers to coexist with NaNs.

Given a series of whole float numbers with missing data,

s = pd.Series([1.0, 2.0, np.nan, 4.0])
s

0    1.0
1    2.0
2    NaN
3    4.0
dtype: float64

s.dtype
# dtype('float64')

You can convert it to a nullable int type (choose from one of Int16, Int32, or Int64) with,

s2 = s.astype('Int32') # note the 'I' is uppercase
s2

0      1
1      2
2    NaN
3      4
dtype: Int32

s2.dtype
# Int32Dtype()

Your column needs to have whole numbers for the cast to happen. Anything else will raise a TypeError:

s = pd.Series([1.1, 2.0, np.nan, 4.0])

s.astype('Int32')
# TypeError: cannot safely cast non-equivalent float64 to int32

As annoyingly non-specific as all the current answers are, they're mostly right but with many caveats, not always mentioned. The gist is, you have two upper-limits, and only one of them is something actually defined, so YMMV:

1. Compile-time limits

Basically, what your compiler will allow. For Visual C++ 2017 on an x64 Windows 10 box, this is my max limit at compile-time before incurring the 2GB limit,

unsigned __int64 max_ints[255999996]{0};

If I did this instead,

unsigned __int64 max_ints[255999997]{0};

I'd get:

Error C1126 automatic allocation exceeds 2G

I'm not sure how 2G correllates to 255999996/7. I googled both numbers, and the only thing I could find that was possibly related was this *nix Q&A about a precision issue with dc. Either way, it doesn't appear to matter which type of int array you're trying to fill, just how many elements can be allocated.

2. Run-time limits

Your stack and heap have their own limitations. These limits are both values that change based on available system resources, as well as how "heavy" your app itself is. For example, with my current system resources, I can get this to run:

int main()
{
    int max_ints[257400]{ 0 };
    return 0;
}

But if I tweak it just a little bit...

int main()
{
    int max_ints[257500]{ 0 };
    return 0;
}

Bam! Stack overflow!

Exception thrown at 0x00007FF7DC6B1B38 in memchk.exe: 0xC00000FD: Stack overflow (parameters: 0x0000000000000001, 0x000000AA8DE03000). Unhandled exception at 0x00007FF7DC6B1B38 in memchk.exe: 0xC00000FD: Stack overflow (parameters: 0x0000000000000001, 0x000000AA8DE03000).

And just to detail the whole heaviness of your app point, this was good to go:

int main()
{
    int maxish_ints[257000]{ 0 };
    int more_ints[400]{ 0 };
    return 0;
}  

But this caused a stack overflow:

int main()
{
    int maxish_ints[257000]{ 0 };
    int more_ints[500]{ 0 };
    return 0;
}  

$http methods return a promise, which can't be iterated, so you have to attach the results to the scope variable through the callbacks:

$scope.documents = [];
$http.get('/Documents/DocumentsList/' + caseId)
  .then(function(result) {
    $scope.documents = result.data;
});

Now, since this defines the documents variable only after the results are fetched, you need to initialise the documents variable on scope beforehand: $scope.documents = []. Otherwise, your ng-repeat will choke.

This way, ng-repeat will first return an empty list, because documents array is empty at first, but as soon as results are received, ng-repeat will run again because the `documents``have changed in the success callback.

Also, you might want to alter you ng-repeat expression to:

<li ng-repeat="document in documents" ng-class="IsFiltered(document.Filtered)">

because if your DisplayDocuments() function is making a call to the server, than this call will be executed many times over, due to the $digest cycles.

var defaultSettings = {
    ajaxsettings: {},
    uisettings: {}
};

Take a look at this site: http://www.json.org/

Also, you can try calling JSON.stringify() on one of your objects from the browser to see the json format. You'd have to do this in the console or a test page.

The jQuery documentation says this "It is also displayed [the handler execution result] if you change the text in the field and then click away. If the field loses focus without the contents having changed, though, the event is not triggered.".

Try the keyup and keydown events, like this:

$("#kat").keydown(function(){ 
   alert("Hello");
});

XDocument is from the LINQ to XML API, and XmlDocument is the standard DOM-style API for XML. If you know DOM well, and don't want to learn LINQ to XML, go with XmlDocument. If you're new to both, check out this page that compares the two, and pick which one you like the looks of better.

I've just started using LINQ to XML, and I love the way you create an XML document using functional construction. It's really nice. DOM is clunky in comparison.

What about something like this:

for /f %%f in ('curl -s -l -u user:pass ftp://ftp.myftpsite.com/') do curl -O -u user:pass ftp://ftp.myftpsite.com/%%f

1. The easiest way is to click on that commit and add a tag to that commit. I have included the tag 'last_commit' with this commit

2. Than go to downloads in the left corner of the side nav in bit bucket. Click on download in the left side

3. Now click on tags in the nav bar and download the zip from the UI. Find your tag and download the zip

Both looks similar, but there are some key points:

1. save() will trigger any overridden Model.save() method, but update() will not trigger this and make a direct update on the database level. So if you have some models with overridden save methods, you must either avoid using update or find another way to do whatever you are doing on that overridden save() methods.

2. obj.save() may have some side effects if you are not careful. You retrieve the object with get(...) and all model field values are passed to your obj. When you call obj.save(), django will save the current object state to record. So if some changes happens between get() and save() by some other process, then those changes will be lost. use save(update_fields=[.....]) for avoiding such problems.

3. Before Django version 1.5, Django was executing a SELECT before INSERT/UPDATE, so it costs 2 query execution. With version 1.5, that method is deprecated.

In here, there is a good guide or save() and update() methods and how they are executed.

In the meantime, a time-window capability was added. See this link.

Note: Recent npm versions do this automatically when package-locks are enabled, so this is not necessary except for removing development packages with the --production flag.

Run npm prune to remove modules not listed in package.json.

From npm help prune:

This command removes "extraneous" packages. If a package name is provided, then only packages matching one of the supplied names are removed.

Extraneous packages are packages that are not listed on the parent package's dependencies list.

If the --production flag is specified, this command will remove the packages specified in your devDependencies.

Call this before the query:

set define off;

Alternatively, hacky:

update t set country = 'Trinidad and Tobago' where country = 'trinidad &' || ' tobago';

From Tuning SQL*Plus:

SET DEFINE OFF disables the parsing of commands to replace substitution variables with their values.

This is holmberd answer with a "table header" implementation

function createTable(tableData) {
  var table = document.createElement('table');
  var header = document.createElement("tr");
  // get first row to be header
  var headers = tableData[0];

  // create table header
  headers.forEach(function(rowHeader){
    var th = document.createElement("th");
    th.appendChild(document.createTextNode(rowHeader));
    header.appendChild(th);
  });      
  console.log(headers);

  // insert table header 
  table.append(header);
  var row = {};
  var cell = {};

  // remove first how - header
  tableData.shift();
  tableData.forEach(function(rowData, index) {
    row = table.insertRow();
    console.log("indice: " + index);
    rowData.forEach(function(cellData) {
      cell = row.insertCell();
            cell.textContent = cellData;
    });
  });
  document.body.appendChild(table);
}

createTable([["row 1, cell 1", "row 1, cell 2"], ["row 2, cell 1", "row 2, cell 2"], ["row 3, cell 1", "row 3, cell 2"]]);

object[] newarray = new object[oldarray.Length-1];

for(int x=0; x < array.Length; x++)
{
  if(!(array[x] == value_of_array_to_delete))
  // if(!(x == array_index_to_delete))
   {
     newarray[x] = oldarray[x];
   }
}

There is no way to downsize an array after it is created, but you can copy the contents to another array of a lesser size.

For the sake of future readers. My problem was that I was specifying an incompatible openssl library to build my program through CMAKE. Projects were generated but build started failing with this error without any other useful information or error. Verbose cmake/compilation logs didn't help either.

My take away lesson is that cross check the incompatibilities in case your program has dependencies on the any other third party library.

If you use the absence of "Mobile" then its almost correct. But there are HTC Sensation 4G (4.3 inch with android 2.X) which does not send Mobile keyword.

The reason why you may want to treat it separately is due to iframes etc.

In my case was Promise with no reject neither resolve, because my Promise function threw an exception. This mistake cause UnhandledPromiseRejectionWarning message.

It may happens because fake png files. You can use this command to check out fake pngs.

cd <YOUR_PROJECT/res/> && find . -name *.png | xargs pngcheck

And then,use ImageEditor(Ex, Pinta) to open fake pngs and re-save them to png.

Good luck.

I think you can also use a postgres backup container which would backup your databases within a given time duration.

  pgbackups:
    container_name: Backup
    image: prodrigestivill/postgres-backup-local
    restart: always
    volumes:
      - ./backup:/backups
    links:
      - db:db
    depends_on:
      - db
    environment:
      - POSTGRES_HOST=db
      - POSTGRES_DB=${DB_NAME} 
      - POSTGRES_USER=${DB_USER}
      - POSTGRES_PASSWORD=${DB_PASSWORD}
      - POSTGRES_EXTRA_OPTS=-Z9 --schema=public --blobs
      - SCHEDULE=@every 0h30m00s
      - BACKUP_KEEP_DAYS=7
      - BACKUP_KEEP_WEEKS=4
      - BACKUP_KEEP_MONTHS=6
      - HEALTHCHECK_PORT=81

Check execution plan of this delete statement. Have a look if index seek is used. Also what is data type of col?

If you are using wrong data type, change update statement (like from '1' to 1 or N'1').

If index scan is used consider using some query hint..

The easy way to display animated GIF directly from URL to your app layout is to use WebView class.

Step 1: In your layout XML

<WebView_x000D_
android:id="@+id/webView"_x000D_
android:layout_width="50dp"_x000D_
android:layout_height="50dp"_x000D_
/>

Step 2: In your Activity

WebView wb;_x000D_
wb = (WebView) findViewById(R.id.webView);_x000D_
wb.loadUrl("https://.......);

Step 3: In your Manifest.XML make Internet permission

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

Step 4: In case you want to make your GIF background transparent and make GIF fit to your Layout

wb.setBackgroundColor(Color.TRANSPARENT);_x000D_
wb.getSettings().setLoadWithOverviewMode(true);_x000D_
wb.getSettings().setUseWideViewPort(true);

The Binder transaction buffer has a limited fixed size, currently 1Mb, which is shared by all transactions in progress for the process. Consequently this exception can be thrown when there are many transactions in progress even when most of the individual transactions are of moderate size.

Never delete this file (ibdata1) because all your data will be deleted!!!
I suggest three ways :

A:
1- Exit from XAMPP control panel.
1- Rename the folder mysql/data to mysql/data_old (you can use any name)
2- Create a new folder mysql/data
3- Copy the content that resides in mysql/backup to the new mysql/data folder
4- Copy all your database folders that are in mysql/data_old to mysql/data (skipping the mysql, performance_schema, and phpmyadmin folders from data_old)
5- Finally copy the ibdata1 file from mysql/data_old and replace it inside mysql/data folder
6- Reastart your system.

B:
1- Stop all sql services.
2- Next, start all sql services again.

C:
1- Open XAMPP control panel
2- Click on Config button, in front of mysql, click on my.ini



3- change client port and server port.

I will go for Inner Join in this context. If I would have used contains, it would iterate 6 times despite if the fact that there are just one match.

var desiredNames = new[] { "Pankaj", "Garg" }; 

var people = new[]  
{  
    new { FirstName="Pankaj", Surname="Garg" },  
    new { FirstName="Marc", Surname="Gravell" },  
    new { FirstName="Jeff", Surname="Atwood" }  
}; 

var records = (from p in people join filtered in desiredNames on p.FirstName equals filtered  select p.FirstName).ToList(); 

Disadvantages of Contains

Suppose I have two list objects.

List 1      List 2
  1           12
  2            7
  3            8
  4           98
  5            9
  6           10
  7            6

Using Contains, it will search for each List 1 item in List 2 that means iteration will happen 49 times !!!

Guess no regex is perfect for this use. I found a pretty solid one here

/(?:(?:https?|ftp|file):\/\/|www\.|ftp\.)(?:\([-A-Z0-9+&@#\/%=~_|$?!:,.]*\)|[-A-Z0-9+&@#\/%=~_|$?!:,.])*(?:\([-A-Z0-9+&@#\/%=~_|$?!:,.]*\)|[A-Z0-9+&@#\/%=~_|$])/igm

Some differences / advantages compared to the other ones posted here:

• It does not match email addresses
• It does match localhost:12345
• It won't detect something like moo.com without http or www

Visio professional has a database reverse-engineering tool built into it. You should be able to use it with MySQL through an ODBC driver. It works best when you reverse engineer the database and then create the diagrams by dragging them off the tables and views panel. It will drag any foreign key objects and put them on the diagram as well.

In my application which calls two services, I compared both Task.Run and Task.Factory.StartNew. I found that in my case both of them work fine. However, the second one is faster.

Here's an update as of Nov 2014. I find that setting method='curl' did the trick for me (while method='auto', does not).

For example:

# does not work
download.file(url='https://s3.amazonaws.com/tripdata/201307-citibike-tripdata.zip',
              destfile='localfile.zip')

# does not work. this appears to be the default anyway
download.file(url='https://s3.amazonaws.com/tripdata/201307-citibike-tripdata.zip',

jupyter kernelspec remove now exists, see #7934.

So you can just.

# List all kernels and grap the name of the kernel you want to remove
jupyter kernelspec list
# Remove it
jupyter kernelspec remove <kernel_name>

That's it.

getDay() returns the day of the week. To get the date, use date.getDate(). getMonth() retrieves the month, but month is zero based, so using getMonth()+1 should give you the right month. Time value seems to be ok here, albeit the hour is 23 here (GMT+1). If you want universal values, add UTC to the methods (e.g. date.getUTCFullYear(), date.getUTCHours())

var timestamp = 1301090400,
date = new Date(timestamp * 1000),
datevalues = [
   date.getFullYear(),
   date.getMonth()+1,
   date.getDate(),
   date.getHours(),
   date.getMinutes(),
   date.getSeconds(),
];
alert(datevalues); //=> [2011, 3, 25, 23, 0, 0]

None of the answers here worked for me. Using FormDataCollection in the post method seems like the right answer but something about my post request was causing webapi to choke. eventually I made it work by including no parameters in the method call and just manually parsing out the form parameters like this.

public HttpResponseMessage FileUpload() {
    System.Web.HttpRequest httpRequest = System.Web.HttpContext.Current.Request;
    System.Collections.Specialized.NameValueCollection formData = httpRequest.Form;
    int ID = Convert.ToInt32(formData["ID"]);
    etc

var startDate = "06/27/2007";
startDate = new Date(startDate);

console.log(startDate);

For those using a Windows OS, I was able to import a large mysqldump file into my local XAMPP installation using this command in cmd.exe:

C:\xampp\mysql\bin>mysql -u {DB_USER} -p {DB_NAME} < path/to/file/ab.sql

Also, I just wrote a more detailed answer to another question on MySQL imports, if this is what you're after.

Moved from the closed topic

del /s d:\test\archive*.txt

This should get you all of your text files

Alternatively,

I modified a script I already wrote to look for certain files to move them, this one should go and find files and delete them. It allows you to just choose to which folder by a selection screen.

Please test this on your system before using it though.

If you change the

set targetFolder= 

to the folder you want you won't get prompted for the folder. *Remember when putting the base path in, the format does not include a '\' on the end. e.g. d:\test c:\temp

Hope this helps

My solution was to add

    location ~ \.php$ {
    try_files $uri =404;
    fastcgi_split_path_info ^(.+\.php)(/.+)$;
    fastcgi_pass unix:/run/php/php7.0-fpm.sock;
    fastcgi_index index.php;
    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    include fastcgi_params;

to my custom configuration file, for example etc/nginx/sites-available/example.com.conf

Adding to /etc/nginx/sites-available/default didn't work for me.

Put this code in onStop() method of MainActivity

@Override

    super.onStop();
    AppUtils.deleteCache(getApplicationContext());

public class AppUtils {
    public static void deleteCache(Context context) {
        try {
            File dir = context.getCacheDir();
            deleteDir(dir);
        } catch (Exception e) {}
    }

    public static boolean deleteDir(File dir) {
        if (dir != null && dir.isDirectory()) {
            String[] children = dir.list();
            for (int i = 0; i < children.length; i++) {
                boolean success = deleteDir(new File(dir, children[i]));
                if (!success) {
                    return false;
                }
            }
            return dir.delete();
        } else if(dir!= null && dir.isFile()) {
            return dir.delete();
        } else {
            return false;
        }

Pass the data like this to the ajax call (http://api.jquery.com/jQuery.ajax/):

data: { userID : userID }

And in your PHP do this:

if(isset($_POST['userID']))
{
    $uid = $_POST['userID'];

    // Do whatever you want with the $uid
}

isset() function's purpose is to check wheter the given variable exists, not to get its value.

Here is an excellent header only class template to measure the elapsed time of a function or any code block:

#ifndef EXECUTION_TIMER_H
#define EXECUTION_TIMER_H

template<class Resolution = std::chrono::milliseconds>
class ExecutionTimer {
public:
    using Clock = std::conditional_t<std::chrono::high_resolution_clock::is_steady,
                                     std::chrono::high_resolution_clock,
                                     std::chrono::steady_clock>;
private:
    const Clock::time_point mStart = Clock::now();

public:
    ExecutionTimer() = default;
    ~ExecutionTimer() {
        const auto end = Clock::now();
        std::ostringstream strStream;
        strStream << "Destructor Elapsed: "
                  << std::chrono::duration_cast<Resolution>( end - mStart ).count()
                  << std::endl;
        std::cout << strStream.str() << std::endl;
    }    

    inline void stop() {
        const auto end = Clock::now();
        std::ostringstream strStream;
        strStream << "Stop Elapsed: "
                  << std::chrono::duration_cast<Resolution>(end - mStart).count()
                  << std::endl;
        std::cout << strStream.str() << std::endl;
    }

}; // ExecutionTimer

#endif // EXECUTION_TIMER_H

Here are some uses of it:

int main() {
    { // empty scope to display ExecutionTimer's destructor's message
         // displayed in milliseconds
         ExecutionTimer<std::chrono::milliseconds> timer;

         // function or code block here

         timer.stop();

    } 

    { // same as above
        ExecutionTimer<std::chrono::microseconds> timer;

        // code block here...

        timer.stop();
    }

    {  // same as above
       ExecutionTimer<std::chrono::nanoseconds> timer;

       // code block here...

       timer.stop();

    }

    {  // same as above
       ExecutionTimer<std::chrono::seconds> timer;

       // code block here...

       timer.stop();

    }              

    return 0;
}

Since the class is a template we can specify real easily in how we want our time to be measured & displayed. This is a very handy utility class template for doing bench marking and is very easy to use.

One simple solution for me that worked was to : - Restart the IDE, since the stop Button was no longer visible.

use the builtin: (no need for tkinter)

s = input('->>')
print(s) # what you just typed); now use if's 

@dsimcha wrote: Counting sort: When you are sorting integers with a limited range

I would change that to:

Counting sort: When you sort positive integers (0 - Integer.MAX_VALUE-2 due to the pigeonhole).

You can always get the max and min values as an efficiency heuristic in linear time as well.
Also you need at least n extra space for the intermediate array and it is stable obviously.

/**
* Some VMs reserve some header words in an array.
* Attempts to allocate larger arrays may result in
* OutOfMemoryError: Requested array size exceeds VM limit
*/
private static final int MAX_ARRAY_SIZE = Integer.MAX_VALUE - 8;

(even though it actually will allow to MAX_VALUE-2) see: Do Java arrays have a maximum size?

Also I would explain that radix sort complexity is O(wn) for n keys which are integers of word size w. Sometimes w is presented as a constant, which would make radix sort better (for sufficiently large n) than the best comparison-based sorting algorithms, which all perform O(n log n) comparisons to sort n keys. However, in general w cannot be considered a constant: if all n keys are distinct, then w has to be at least log n for a random-access machine to be able to store them in memory, which gives at best a time complexity O(n log n). (from wikipedia)

I don't know if this is accurate, but I have found that python/ruby works much better for scripts that have a lot of mathematical computations. Otherwise you have to use dc or some other "arbitrary precision calculator". It just becomes a very big pain. With python you have much more control over floats vs ints and it is much easier to perform a lot of computations and sometimes.

In particular, I would never work with a bash script to handle binary information or bytes. Instead I would use something like python (maybe) or C++ or even Node.JS.

The easiest thing to do would be to insert the elements with the disabled attribute.

<input type="hidden" name="not_gonna_submit" disabled="disabled" value="invisible" />

This way you can still access them as children of the form.

Disabled fields have the downside that the user can't interact with them at all- so if you have a disabled text field, the user can't select the text. If you have a disabled checkbox, the user can't change its state.

You could also write some javascript to fire on form submission to remove the fields you don't want to submit.

Use process.wait() after you call process.communicate().
For example:

import subprocess

process = subprocess.Popen(['ipconfig', '/all'], stderr=subprocess.PIPE, stdout=subprocess.PIPE)
stdout, stderr = process.communicate()
exit_code = process.wait()
print(stdout, stderr, exit_code)

As of jQuery 1.5, there is a headers hash you can pass in as follows:

$.ajax({
    url: "/test",
    headers: {"X-Test-Header": "test-value"}
});

From http://api.jquery.com/jQuery.ajax:

headers (added 1.5): A map of additional header key/value pairs to send along with the request. This setting is set before the beforeSend function is called; therefore, any values in the headers setting can be overwritten from within the beforeSend function.

You can use Date.getTime() which:

Returns the number of milliseconds since January 1, 1970, 00:00:00 GMT represented by this Date object.

This means you can compare them just like numbers:

if (date1.getTime() <= date.getTime() && date.getTime() <= date2.getTime()) {
    /*
     * date is between date1 and date2 (both inclusive)
     */
}

/*
 * when date1 = 2015-01-01 and date2 = 2015-01-10 then
 * returns true for:
 * 2015-01-01
 * 2015-01-01 00:00:01
 * 2015-01-02
 * 2015-01-10
 * returns false for:
 * 2014-12-31 23:59:59
 * 2015-01-10 00:00:01
 * 
 * if one or both dates are exclusive then change <= to <
 */

put this code in your code..

error_reporting(-1);
ini_set('display_errors', 'On');

What you can utilize is some sort of templating engine like pug (formerly jade). To enable it you should do the following:

1. npm install --save pug - to add it to the project and package.json file
2. app.set('view engine', 'pug'); - register it as a view engine in express
3. create a ./views folder and add a simple .pug file like so:

html
  head
    title= title
  body
    h1= message

note that the spacing is very important!

4. create a route that returns the processed html:

app.get('/', function (req, res) {
  res.render('index', { title: 'Hey', message: 'Hello there!'});
});

This will render an index.html page with the variables passed in node.js changed to the values you have provided. This has been taken directly from the expressjs templating engine page: http://expressjs.com/en/guide/using-template-engines.html

For more info on pug you can also check: https://github.com/pugjs/pug

As others have pointed out, you need to disable extensions and retry the page to see if errors reoccur. If not, then the culprit might be one (or more) of them.

On my own case it was a deprecated switch, I've set up long ago. I used process-per-tab which was getting phased-out in recent (48-53) versions. Once I removed that switch all started to work correctly.

Stick to php...

Why not only allow the button to appear once an above criteria is met.

<?
if (whatever == something) {
    $display = '<input id="Button" type="button" value="+" style="background-color:grey" onclick="Me();"/>';
    return $display;
}
?>

My understanding is that set and get are for computed properties (no backing from stored properties)

_{if you are coming from an Objective-C bare in mind that the naming conventions have changed. In Swift an iVar or instance variable is named stored property}

Example 1 (read only property) - with warning:

var test : Int {
    get {
        return test
    }
}

This will result in a warning because this results in a recursive function call (the getter calls itself).The warning in this case is "Attempting to modify 'test' within its own getter".

Example 2. Conditional read/write - with warning

var test : Int {
    get {
        return test
    }
    set (aNewValue) {
        //I've contrived some condition on which this property can be set
        //(prevents same value being set)
        if (aNewValue != test) {
            test = aNewValue
        }
    }
}

Similar problem - you cannot do this as it's recursively calling the setter. Also, note this code will not complain about no initialisers as there is no stored property to initialise.

Example 3. read/write computed property - with backing store

Here is a pattern that allows conditional setting of an actual stored property

//True model data
var _test : Int = 0

var test : Int {
    get {
        return _test
    }
    set (aNewValue) {
        //I've contrived some condition on which this property can be set
        if (aNewValue != test) {
            _test = aNewValue
        }
    }
}

Note The actual data is called _test (although it could be any data or combination of data) Note also the need to provide an initial value (alternatively you need to use an init method) because _test is actually an instance variable

Example 4. Using will and did set

//True model data
var _test : Int = 0 {

    //First this
    willSet {
        println("Old value is \(_test), new value is \(newValue)")
    }

    //value is set

    //Finaly this
    didSet {
        println("Old value is \(oldValue), new value is \(_test)")
    }
}

var test : Int {
    get {
        return _test
    }
    set (aNewValue) {
        //I've contrived some condition on which this property can be set
        if (aNewValue != test) {
            _test = aNewValue
        }
    }
}

Here we see willSet and didSet intercepting a change in an actual stored property. This is useful for sending notifications, synchronisation etc... (see example below)

Example 5. Concrete Example - ViewController Container

//Underlying instance variable (would ideally be private)
var _childVC : UIViewController? {
    willSet {
        //REMOVE OLD VC
        println("Property will set")
        if (_childVC != nil) {
            _childVC!.willMoveToParentViewController(nil)
            self.setOverrideTraitCollection(nil, forChildViewController: _childVC)
            _childVC!.view.removeFromSuperview()
            _childVC!.removeFromParentViewController()
        }
        if (newValue) {
            self.addChildViewController(newValue)
        }

    }

    //I can't see a way to 'stop' the value being set to the same controller - hence the computed property

    didSet {
        //ADD NEW VC
        println("Property did set")
        if (_childVC) {
//                var views  = NSDictionaryOfVariableBindings(self.view)    .. NOT YET SUPPORTED (NSDictionary bridging not yet available)

            //Add subviews + constraints
            _childVC!.view.setTranslatesAutoresizingMaskIntoConstraints(false)       //For now - until I add my own constraints
            self.view.addSubview(_childVC!.view)
            let views = ["view" : _childVC!.view] as NSMutableDictionary
            let layoutOpts = NSLayoutFormatOptions(0)
            let lc1 : AnyObject[] = NSLayoutConstraint.constraintsWithVisualFormat("|[view]|",  options: layoutOpts, metrics: NSDictionary(), views: views)
            let lc2 : AnyObject[] = NSLayoutConstraint.constraintsWithVisualFormat("V:|[view]|", options: layoutOpts, metrics: NSDictionary(), views: views)
            self.view.addConstraints(lc1)
            self.view.addConstraints(lc2)

            //Forward messages to child
            _childVC!.didMoveToParentViewController(self)
        }
    }
}


//Computed property - this is the property that must be used to prevent setting the same value twice
//unless there is another way of doing this?
var childVC : UIViewController? {
    get {
        return _childVC
    }
    set(suggestedVC) {
        if (suggestedVC != _childVC) {
            _childVC = suggestedVC
        }
    }
}

Note the use of BOTH computed and stored properties. I've used a computed property to prevent setting the same value twice (to avoid bad things happening!); I've used willSet and didSet to forward notifications to viewControllers (see UIViewController documentation and info on viewController containers)

I hope this helps, and please someone shout if I've made a mistake anywhere here!

I am wondering when to use static methods?

1. A common use for static methods is to access static fields.

2. But you can have static methods, without referencing static variables. Helper methods without referring static variable can be found in some java classes like java.lang.Math

   public static int min(int a, int b) {
       return (a <= b) ? a : b;
   }
   

3. The other use case, I can think of these methods combined with synchronized method is implementation of class level locking in multi threaded environment.

Say if I have a class with a few getters and setters, a method or two, and I want those methods only to be invokable on an instance object of the class. Does this mean I should use a static method?

If you need to access method on an instance object of the class, your method should should be non static.

Oracle documentation page provides more details.

Not all combinations of instance and class variables and methods are allowed:

1. Instance methods can access instance variables and instance methods directly.
2. Instance methods can access class variables and class methods directly.
3. Class methods can access class variables and class methods directly.
4. Class methods cannot access instance variables or instance methods directly—they must use an object reference. Also, class methods cannot use the this keyword as there is no instance for this to refer to.

If you want to pull out only the index values for certain integer-based row-indices, you can do something like the following using the iloc method:

In [28]: temp
Out[28]:
       index                 time  complete
row_0      2  2014-10-22 01:00:00         0
row_1      3  2014-10-23 14:00:00         0
row_2      4  2014-10-26 08:00:00         0
row_3      5  2014-10-26 10:00:00         0
row_4      6  2014-10-26 11:00:00         0

In [29]: temp.iloc[[0,1,4]].index
Out[29]: Index([u'row_0', u'row_1', u'row_4'], dtype='object')

In [30]: temp.iloc[[0,1,4]].index.tolist()
Out[30]: ['row_0', 'row_1', 'row_4']

I think this is the simplest alias, add to your ~/.gitconfig

[alias]
  publish-branch = !git push -u origin $(git rev-parse --abbrev-ref HEAD)

You just run

git publish-branch

and... it publishes the branch

I know this is old, but also make sure that none of your docker containers are already on port 80. That was my issue.

Heres another approach.

HTML:

<input type='text' id="pointspossible" class="clsInput" />
<input type='text' id="pointsgiven"  class="clsInput" />
<button id="btnCalculate">Calculate</button>
<input type='text' id="pointsperc" disabled/>

JS Code:

function isNumeric(n) {
    return !isNaN(parseFloat(n)) && isFinite(n);
}


$('#btnCalculate').on('click', function() {
    var a = $('#pointspossible').val().replace(/ +/g, "");
    var b = $('#pointsgiven').val().replace(/ +/g, "");
    var perc = "0";
    if (a.length > 0 && b.length > 0) {
        if (isNumeric(a) && isNumeric(b)) {
            perc = a / b * 100;
        }
    }    
    $('#pointsperc').val(perc).toFixed(3);
});

I got this answer from the book Programming iOS 7, section Bar Position and Bar Metrics

If a navigation bar or toolbar — or a search bar (discussed earlier in this chapter) — is to occupy the top of the screen, the iOS 7 convention is that its height should be increased to underlap the transparent status bar. To make this possible, iOS 7 introduces the notion of a bar position.

UIBarPositionTopAttached

Specifies that the bar is at the top of the screen, as well as its containing view. Bars with this position draw their background extended upwards, allowing their background content to show through the status bar. Available in iOS 7.0 and later.

This should work for both strings and unicode objects in Python2, and both strings and bytes in Python3:

# python <3.0
def only_numerics(seq):
    return filter(type(seq).isdigit, seq)

# python =3.0
def only_numerics(seq):
    seq_type= type(seq)
    return seq_type().join(filter(seq_type.isdigit, seq))

The simplest approach is to set the date of the individual log files to be older than the retention period. Then the broker should clean them up and remove them for you within a few seconds. This offers several advantages:

1. No need to bring down brokers, it's a runtime operation.
2. Avoids the possibility of invalid offset exceptions (more on that below).

In my experience with Kafka 0.7.x, removing the log files and restarting the broker could lead to invalid offset exceptions for certain consumers. This would happen because the broker restarts the offsets at zero (in the absence of any existing log files), and a consumer that was previously consuming from the topic would reconnect to request a specific [once valid] offset. If this offset happens to fall outside the bounds of the new topic logs, then no harm and the consumer resumes at either the beginning or the end. But, if the offset falls within the bounds of the new topic logs, the broker attempts to fetch the message set but fails because the offset doesn't align to an actual message.

This could be mitigated by also clearing the consumer offsets in zookeeper for that topic. But if you don't need a virgin topic and just want to remove the existing contents, then simply 'touch'-ing a few topic logs is far easier and more reliable, than stopping brokers, deleting topic logs, and clearing certain zookeeper nodes.

A possible solution is using the collect_list() function from pyspark.sql.functions. This will aggregate all column values into a pyspark array that is converted into a python list when collected:

mvv_list   = df.select(collect_list("mvv")).collect()[0][0]
count_list = df.select(collect_list("count")).collect()[0][0] 

For your first method change ws.Range("A") to ws.Range("A:A") which will search the entirety of column a, like so:

Sub Find_Bingo()

        Dim wb As Workbook
        Dim ws As Worksheet
        Dim FoundCell As Range
        Set wb = ActiveWorkbook
        Set ws = ActiveSheet

            Const WHAT_TO_FIND As String = "Bingo"

            Set FoundCell = ws.Range("A:A").Find(What:=WHAT_TO_FIND)
            If Not FoundCell Is Nothing Then
                MsgBox (WHAT_TO_FIND & " found in row: " & FoundCell.Row)
            Else
                MsgBox (WHAT_TO_FIND & " not found")
            End If
End Sub

For your second method, you are using Bingo as a variable instead of a string literal. This is a good example of why I add Option Explicit to the top of all of my code modules, as when you try to run the code it will direct you to this "variable" which is undefined and not intended to be a variable at all.

Additionally, when you are using With...End With you need a period . before you reference Cells, so Cells should be .Cells. This mimics the normal qualifying behavior (i.e. Sheet1.Cells.Find..)

Change Bingo to "Bingo" and change Cells to .Cells

With Sheet1
        Set FoundCell = .Cells.Find(What:="Bingo", After:=.Cells(1, 1), _
        LookIn:=xlValues, lookat:=xlPart, SearchOrder:=xlByRows, _
        SearchDirection:=xlNext, MatchCase:=False, SearchFormat:=False)
    End With

If Not FoundCell Is Nothing Then
        MsgBox ("""Bingo"" found in row " & FoundCell.Row)
Else
        MsgBox ("Bingo not found")
End If

Update

In my

With Sheet1
    .....
End With

The Sheet1 refers to a worksheet's code name, not the name of the worksheet itself. For example, say I open a new blank Excel workbook. The default worksheet is just Sheet1. I can refer to that in code either with the code name of Sheet1 or I can refer to it with the index of Sheets("Sheet1"). The advantage to using a codename is that it does not change if you change the name of the worksheet.

Continuing this example, let's say I renamed Sheet1 to Data. Using Sheet1 would continue to work, as the code name doesn't change, but now using Sheets("Sheet1") would return an error and that syntax must be updated to the new name of the sheet, so it would need to be Sheets("Data").

In the VB Editor you would see something like this:

Notice how, even though I changed the name to Data, there is still a Sheet1 to the left. That is what I mean by codename.

The Data worksheet can be referenced in two ways:

Debug.Print Sheet1.Name
Debug.Print Sheets("Data").Name

Both should return Data

Using Integer.parseIn(String), you can parse string value into integer. Also you need to catch exception in case if input string is not a proper number.

int x = 0;

try {       
    x = Integer.parseInt("100"); // Parse string into number
} catch (NumberFormatException e) {
    e.printStackTrace();
}

Here's an example, because an example is often clearer than a long explanation. Suppose foo is a variable of type long. The following operation is not an atomic operation:

foo = 65465498L;

Indeed, the variable is written using two separate operations: one that writes the first 32 bits, and a second one which writes the last 32 bits. That means that another thread might read the value of foo, and see the intermediate state.

Making the operation atomic consists in using synchronization mechanisms in order to make sure that the operation is seen, from any other thread, as a single, atomic (i.e. not splittable in parts), operation. That means that any other thread, once the operation is made atomic, will either see the value of foo before the assignment, or after the assignment. But never the intermediate value.

A simple way of doing this is to make the variable volatile:

private volatile long foo;

Or to synchronize every access to the variable:

public synchronized void setFoo(long value) {
    this.foo = value;
}

public synchronized long getFoo() {
    return this.foo;
}
// no other use of foo outside of these two methods, unless also synchronized

Or to replace it with an AtomicLong:

private AtomicLong foo;

// wrapper function to protect inner variable tempArray from global scope;
function flattenArray(arr) {

  let tempArray = [];

  function flatten(arr) {
    arr.forEach(function(element) {
      Array.isArray(element) ? flatten(element) : tempArray.push(element);     // ternary check that calls flatten() again if element is an array, hereby making flatten() recursive.
    });
  }

  // calling the inner flatten function, and then returning the temporary array
  flatten(arr);
  return tempArray;
}

// example usage:
let flatArray = flattenArray(nestedArray);

Here's another reason: All the header paths seemed fine, but we still had an error in the precompiled (.pch) file trying to read a pod header

(i.e. #import <CocoaLumberjack/CocoaLumberjack.h>).

Looking at the raw build output, I finally noticed that the error was breaking our Watch OS Extension Target, not the main target we were building, because we were also importing the .pch precompiled header file into the Watch OS targets, and it was failing there. Make sure your accompanying Watch OS target settings don't try to import the .pch file (especially if you set that import from the master target setting, like I did!)

It's simply “No such directory entry”. Since directory entries can be directories or files (or symlinks, or sockets, or pipes, or devices), the name ENOFILE would have been too narrow in its meaning.

Below code gets .yaml files from a custom resource directory.

ClassLoader classLoader = this.getClass().getClassLoader();

                log.debug("pattern {} ", pattern.pattern());
                ApplicationHome home = new ApplicationHome(SomeApplication.class);
                JarFile file = new JarFile(home.getSource());
                Enumeration<JarEntry>  jarEntries = file.entries() ;
                while(jarEntries.hasMoreElements()){
                    JarEntry entry = jarEntries.nextElement();
                    Matcher matcher = pattern.matcher(entry.getName());
                    if(matcher.find()){
                        InputStream in =
                                file.getInputStream(entry);
                        //work on the stream
    
    
                    }

                String path = uri.getPath();
                File[] files = new File(path).listFiles();
               
                for(File file: files){
                    if(file != null){

                        }
                    }else{

The font tag has been deprecated for some time now.

That being said, the reason why both of your tables display with the same font size is that the 'size' attribute only accepts values ranging from 1 - 7. The smallest size is 1. The largest size is 7. The default size is 3. Any values larger than 7 will just display the same as if you had used 7, because 7 is the maximum value allowed.

And as @Alex H said, you should be using CSS for this.

You can use this, but remember that your query gives 1 result, multiple results will throw the exception.

declare @ModelID uniqueidentifer
Set @ModelID = (select Top(1) modelid from models where areaid = 'South Coast')

Another way:

Select Top(1)@ModelID = modelid from models where areaid = 'South Coast'

str = 'This is an example'
n = 7
result = substr(str,(nchar(str)+1)-n,nchar(str))
print(result)

Line numbers were added to the IDLE editor two days ago and will appear in the upcoming 3.8.0a3 and later 3.7.5. For new windows, they are off by default, but this can be reversed on the Setting dialog, General tab, Editor section. For existing windows, there is a new Show (Hide) Line Numbers entry on the Options menu. There is currently no hotkey. One can select a line or bloc of lines by clicking on a line or clicking and dragging.

Some people may have missed Edit / Go to Line. The right-click context menu Goto File/Line works on grep (Find in Files) output as well as on trackbacks.

You should use ::ng-deep instead of /deep/ which seems to be deprecated.

Per documentation:

The shadow-piercing descendant combinator is deprecated and support is being removed from major browsers and tools. As such we plan to drop support in Angular (for all 3 of /deep/, >>> and ::ng-deep). Until then ::ng-deep should be preferred for a broader compatibility with the tools.

You can find it here

To remove only spaces use str.replace:

sentence = sentence.replace(' ', '')

To remove all whitespace characters (space, tab, newline, and so on) you can use split then join:

sentence = ''.join(sentence.split())

or a regular expression:

import re
pattern = re.compile(r'\s+')
sentence = re.sub(pattern, '', sentence)

If you want to only remove whitespace from the beginning and end you can use strip:

sentence = sentence.strip()

You can also use lstrip to remove whitespace only from the beginning of the string, and rstrip to remove whitespace from the end of the string.

I would suggest you to use Moment.js http://momentjs.com/

Then you can do:

moment(new Date()).format("YYYY/MM/DD");

Note: you don't actualy need to add new Date() if you want the current TimeDate, I only added it as a reference that you can pass a date object to it. for the current TimeDate this also works:

moment().format("YYYY/MM/DD");

READING the <textarea>'s content:

var text1 = document.getElementById('myTextArea').value;     // plain JavaScript
var text2 = $("#myTextArea").val();                          // jQuery

WRITING to the <textarea>':

document.getElementById('myTextArea').value = 'new value';   // plain JavaScript
$("#myTextArea").val('new value');                           // jQuery

See DEMO JSFiddle here.

Do not use .html() or .innerHTML!

jQuery's .html() and JavaScript's .innerHTML should not be used, as they do not pick up changes to the textarea's text.

When the user types on the textarea, the .html() won't return the typed value, but the original one -- check demo fiddle above for an example.

I agree with Brandrew, the problem is most likely caused by some missing dlls that can't be found neither on the system path nor in the folder where the executable is. Try putting the following DLLs nearby the executable:

• the Visual Studio C++ runtime (in VS2008, they could be found at places like C:\Program Files\Microsoft Visual Studio 9.0\VC\redist\x86.) Include all 3 of the DLL files as well as the manifest file.
• the four OpenCV dlls (cv210.dll, cvaux210.dll, cxcore210.dll and highgui210.dll, or the ones your OpenCV version has)
• if that still doesn't work, try the debug VS runtime (executables compiled for "Debug" use a different set of dlls, named something like msvcrt9d.dll, important part is the "d")

Alternatively, try loading the executable into Dependency Walker ( http://www.dependencywalker.com/ ), it should point out the missing dlls for you.

Regarding jQuery, the following common methods will also remove other constructs such as data and event handlers:

remove()

In addition to the elements themselves, all bound events and jQuery data associated with the elements are removed.

empty()

To avoid memory leaks, jQuery removes other constructs such as data and event handlers from the child elements before removing the elements themselves.

html()

Additionally, jQuery removes other constructs such as data and event handlers from child elements before replacing those elements with the new content.

It was pretty exciting to make this method work, so it makes a clone of a function using Function call.

Some limitations about closures described at MDN Function Reference

function cloneFunc( func ) {
  var reFn = /^function\s*([^\s(]*)\s*\(([^)]*)\)[^{]*\{([^]*)\}$/gi
    , s = func.toString().replace(/^\s|\s$/g, '')
    , m = reFn.exec(s);
  if (!m || !m.length) return; 
  var conf = {
      name : m[1] || '',
      args : m[2].replace(/\s+/g,'').split(','),
      body : m[3] || ''
  }
  var clone = Function.prototype.constructor.apply(this, [].concat(conf.args, conf.body));
  return clone;
}

Enjoy.

If you're already using Boost, you can do it with boost string algorithms + boost lexical cast:

#include <boost/algorithm/string/predicate.hpp>
#include <boost/lexical_cast.hpp>

try {    
    if (boost::starts_with(argv[1], "--foo="))
        foo_value = boost::lexical_cast<int>(argv[1]+6);
} catch (boost::bad_lexical_cast) {
    // bad parameter
}

This kind of approach, like many of the other answers provided here is ok for very simple tasks, but in the long run you are usually better off using a command line parsing library. Boost has one (Boost.Program_options), which may make sense if you happen to be using Boost already.

Otherwise a search for "c++ command line parser" will yield a number of options.

On my machine a PID was not being shown from this command netstat -tulpn for the in-use port (8080), so i could not kill it, killing the containers and restarting the computer did not work. So service docker restart command restarted docker for me (ubuntu) and the port was no longer in use and i am a happy chap and off to lunch.

If you would like to support really old browsers you should parse the date string, since using the ISO8601 date format with the Date constructor is not supported pre IE9:

var queryDate = '2009-11-01',
    dateParts = queryDate.match(/(\d+)/g)
    realDate = new Date(dateParts[0], dateParts[1] - 1, dateParts[2]);  
                                    // months are 0-based!
// For >= IE9
var realDate = new Date('2009-11-01');  

$('#datePicker').datepicker({ dateFormat: 'yy-mm-dd' }); // format to show
$('#datePicker').datepicker('setDate', realDate);

Check the above example here.

You use List#get(int index) to get an object with the index index in the list. You use it like that:

List<ExampleClass> list = new ArrayList<ExampleClass>();
list.add(new ExampleClass());
list.add(new ExampleClass());
list.add(new ExampleClass());
ExampleClass exampleObj = list.get(2); // will get the 3rd element in the list (index 2);

Change your positioning a bit:

.container {
    border: 1px solid #DDDDDD;
    width: 200px;
    height: 200px;
    position:relative;
}
.tag {
    float: left;
    position: absolute;
    left: 0px;
    top: 0px;
    background-color: green;
}

jsFiddle example

You need to set relative positioning on the container and then absolute on the inner tag div. The inner tag's absolute positioning will be with respect to the outer relatively positioned div. You don't even need the z-index rule on the tag div.

Using MongoDB 4.0 and newer

You have two options i.e. $toInt or $convert. Using $toInt, follow the example below:

filterDateStage = {
    '$match': {
        'Date': {
            '$gt': '2015-04-01', 
            '$lt': '2015-04-05'
        }
    }
};

groupStage = {
    '$group': {
        '_id': '$PartnerID',
        'total': { '$sum': { '$toInt': '$moop' } }
    }
};

db.getCollection('my_collection').aggregate([
   filterDateStage,
   groupStage
])

If the conversion operation encounters an error, the aggregation operation stops and throws an error. To override this behavior, use $convert instead.

Using $convert

groupStage = {
    '$group': {
        '_id': '$PartnerID',
        'total': { 
            '$sum': { 
                '$convert': { 'input': '$moop', 'to': 'int' }
            } 
        }
    }
};

Using Map/Reduce

With map/reduce you can use javascript functions like parseInt() to do the conversion. As an example, you could define the map function to process each input document: In the function, this refers to the document that the map-reduce operation is processing. The function maps the converted moop string value to the PartnerID for each document and emits the PartnerID and converted moop pair. This is where the javascript native function parseInt() can be applied:

var mapper = function () {
    var x = parseInt(this.moop);
    emit(this.PartnerID, x);
};

Next, define the corresponding reduce function with two arguments keyCustId and valuesMoop. valuesMoop is an array whose elements are the integer moop values emitted by the map function and grouped by keyPartnerID. The function reduces the valuesMoop array to the sum of its elements.

var reducer = function(keyPartnerID, valuesMoop) {
                  return Array.sum(valuesMoop);
              };

db.collection.mapReduce(
    mapper,
    reducer,
    {
        out : "example_results",
        query: { 
            Date: {
                $gt: "2015-04-01", 
                $lt: "2015-04-05"
            }
        }       
    }
 );

 db.example_results.find(function (err, docs) {
    if(err) console.log(err);
    console.log(JSON.stringify(docs));
 });

For example, with the following sample collection of documents:

/* 0 */
{
    "_id" : ObjectId("550c00f81bcc15211016699b"),
    "Date" : "2015-04-04",
    "PartnerID" : "123456",
    "moop" : "1234"
}

/* 1 */
{
    "_id" : ObjectId("550c00f81bcc15211016699c"),
    "Date" : "2015-04-03",
    "PartnerID" : "123456",
    "moop" : "24"
}

/* 2 */
{
    "_id" : ObjectId("550c00f81bcc15211016699d"),
    "Date" : "2015-04-02",
    "PartnerID" : "123457",
    "moop" : "21"
}

/* 3 */
{
    "_id" : ObjectId("550c00f81bcc15211016699e"),
    "Date" : "2015-04-02",
    "PartnerID" : "123457",
    "moop" : "8"
}

The above Map/Reduce operation will save the results to the example_results collection and the shell command db.example_results.find() will give:

/* 0 */
{
    "_id" : "123456",
    "value" : 1258
}

/* 1 */
{
    "_id" : "123457",
    "value" : 29
}

In newer versions of Notepad++ (currently 5.9), this option is under:

View->Show Symbol->Show All Characters

or

View->Show Symbol->Show White Space and Tab

Starting with ElasticSearch 7.4, the best method to rename an index is to copy the index using the newly introduced Clone Index API, then to delete the original index using the Delete Index API.

The main advantage of the Clone Index API over the use of the Snapshot API or the Reindex API for the same purpose is speed, since the Clone Index API hardlinks segments from the source index to the target index, without reprocessing any of its content (on filesystems that support hardlinks, obviously; otherwise, files are copied at the file system level, which is still much more efficient that the alternatives). Clone Index also guarantee that the target index is identical in every point to the source index (that is, there is no need to manually copy settings and mappings, contrary to the Reindex approach), and doesn't require a local snapshot directory be configured.

Side note: even though this procedure is much faster than previous solutions, it still implies down time. There are real use cases that justify renaming indices (for example, as a step in a split, shrink or backup workflow), but renaming indices should not be part of day-to-day operations. If your workflow requires frequent index renaming, then you should consider using Indices Aliases instead.

Here is an example of a complete sequence of operations to rename index source_index to target_index. It can be executed using some ElasticSearch specific console, such as the one integrated in Kibana. See this gist for an alternative version of this example, using curl instead of an Elastic Search console.

# Make sure the source index is actually open
POST /source_index/_open

# Put the source index in read-only mode
PUT /source_index/_settings
{
  "settings": {
    "index.blocks.write": "true"
  }
}

# Clone the source index to the target name, and set the target to read-write mode
POST /source_index/_clone/target_index
{
  "settings": {
    "index.blocks.write": null 
  }
}

# Wait until the target index is green;
# it should usually be fast (assuming your filesystem supports hard links).
GET /_cluster/health/target_index?wait_for_status=green&timeout=30s

# If it appears to be taking too much time for the cluster to get back to green,
# the following requests might help you identify eventual outstanding issues (if any)
GET /_cat/indices/target_index
GET /_cat/recovery/target_index
GET /_cluster/allocation/explain

# Delete the source index
DELETE /source_index

Jul 2019 - Dedicated hook/function

A dedicated hook/function can hide implementation details, and provides a simple API to your components.

React 16.8 + Functional Component

const useScroll = () => {
  const elRef = useRef(null);
  const executeScroll = () => elRef.current.scrollIntoView();

  return [executeScroll, elRef];
};

Use it in any functional component.

const ScrollDemo = () => {
    const [executeScroll, elRef] = useScroll()
    useEffect(executeScroll, []) // Runs after component mounts
    
    return <div ref={elRef}>Element to scroll to</div> 
}

React 16.3 + class Component

const utilizeScroll = () => {
  const elRef = React.createRef();
  const executeScroll = () => elRef.current.scrollIntoView();

  return { executeScroll, elRef };
};

Use it in any class component.

class ScrollDemo extends Component {
  constructor(props) {
    super(props);
    this.elScroll = utilizeScroll();
  }

  componentDidMount() {
    this.elScroll.executeScroll();

} 

Full demo

You should write your own stream manipulator

• http://www.two-sdg.demon.co.uk/curbralan/papers/WritingStreamManipulators.html

cout << multi(5) << "whatever" << "lolcat";

Try another *fastcgi_param* something like

fastcgi_param SCRIPT_FILENAME /usr/share/nginx/html$fastcgi_script_name;

Simply, You can make this method static as below:

public static void startChronometer(){
    mChronometer.start();
    showElapsedTime();
} 

you can call this function in other class as below:

MainActivity.startChronometer();

export will make the variable available to all shells forked from the current shell.

Ben is completely correct in his answer - so keep what he says in mind. What I'm about to tell you isn't a full explanation, but it's a very easy way to remember how e.target, e.currentTarget work in relation to mouse events and the display list:

e.target = The thing under the mouse (as ben says... the thing that triggers the event). e.currentTarget = The thing before the dot... (see below)

So if you have 10 buttons inside a clip with an instance name of "btns" and you do:

btns.addEventListener(MouseEvent.MOUSE_OVER, onOver);
// btns = the thing before the dot of an addEventListener call
function onOver(e:MouseEvent):void{
  trace(e.target.name, e.currentTarget.name);
}

e.target will be one of the 10 buttons and e.currentTarget will always be the "btns" clip.

It's worth noting that if you changed the MouseEvent to a ROLL_OVER or set the property btns.mouseChildren to false, e.target and e.currentTarget will both always be "btns".

you should check ios UITableViewDataSourcePrefetching.

class ViewController: UIViewController {
    @IBOutlet weak var mytableview: UITableView!

    override func viewDidLoad() {
        super.viewDidLoad()
        mytableview.prefetchDataSource = self
    }

 func tableView(_ tableView: UITableView, prefetchRowsAt indexPaths: [IndexPath]) {
        print("prefetchdRowsAtIndexpath \(indexPaths)")
    }

    func tableView(_ tableView: UITableView, cancelPrefetchingForRowsAt indexPaths: [IndexPath]) {
        print("cancelPrefetchingForRowsAtIndexpath \(indexPaths)")
    }


}

• https://developer.apple.com/documentation/uikit/uitableviewdatasourceprefetching https://andreygordeev.com/2017/02/20/uitableview-prefetching/

I fixed the issue by using these command lines

• $ rm -rf node_modules/
• $ sudo npm update -g npm
• $ npm install

It's done!

You can do:

<hr style="border-bottom: dotted 1px #000" />

Checkout this, This is from PHP MANUAL, This may help you.

If you're using PHP_CLI SAPI and getting error "Maximum execution time of N seconds exceeded" where N is an integer value, try to call set_time_limit(0) every M seconds or every iteration. For example:

<?php

require_once('db.php');

$stmt = $db->query($sql);

while ($row = $stmt->fetchRow()) {
    set_time_limit(0);
    // your code here
}

?>

Here is a quick extension method you can use that mimics PHP syntax. Include AssemblyName.Extensions to the code file you are using the extension in.

Then you could call:

input.SubstringReverse(-5) and it will return "Three".

namespace AssemblyName.Extensions {

    public static class StringExtensions
    {
        /// <summary>
        /// Takes a negative integer - counts back from the end of the string.
        /// </summary>
        /// <param name="str"></param>
        /// <param name="length"></param>
        public static string SubstringReverse(this string str, int length)
        {
            if (length > 0) 
            {
                throw new ArgumentOutOfRangeException("Length must be less than zero.");
            }

            if (str.Length < Math.Abs(length))
            {
                throw new ArgumentOutOfRangeException("Length cannot be greater than the length of the string.");
            }

            return str.Substring((str.Length + length), Math.Abs(length));
        }
    }
}

Look at strtok(). strtok() is not a re-entrant function.

strtok_r() is the re-entrant version of strtok(). Here's an example program from the manual:

   #include <stdio.h>
   #include <stdlib.h>
   #include <string.h>

   int main(int argc, char *argv[])
   {
       char *str1, *str2, *token, *subtoken;
       char *saveptr1, *saveptr2;
       int j;

       if (argc != 4) {
           fprintf(stderr, "Usage: %s string delim subdelim\n",argv[0]);
           exit(EXIT_FAILURE);
       }

       for (j = 1, str1 = argv[1]; ; j++, str1 = NULL) {
           token = strtok_r(str1, argv[2], &saveptr1);
           if (token == NULL)
               break;
           printf("%d: %s\n", j, token);

           for (str2 = token; ; str2 = NULL) {
               subtoken = strtok_r(str2, argv[3], &saveptr2);
               if (subtoken == NULL)
                   break;
               printf(" --> %s\n", subtoken);
           }
       }

       exit(EXIT_SUCCESS);
   }

Sample run which operates on subtokens which was obtained from the previous token based on a different delimiter:

$ ./a.out hello:word:bye=abc:def:ghi = :

1: hello:word:bye
 --> hello
 --> word
 --> bye
2: abc:def:ghi
 --> abc
 --> def
 --> ghi

I know it's been said already, but I'd highly recommend the requests Python package.

If you've used languages other than python, you're probably thinking urllib and urllib2 are easy to use, not much code, and highly capable, that's how I used to think. But the requests package is so unbelievably useful and short that everyone should be using it.

First, it supports a fully restful API, and is as easy as:

import requests

resp = requests.get('http://www.mywebsite.com/user')
resp = requests.post('http://www.mywebsite.com/user')
resp = requests.put('http://www.mywebsite.com/user/put')
resp = requests.delete('http://www.mywebsite.com/user/delete')

Regardless of whether GET / POST, you never have to encode parameters again, it simply takes a dictionary as an argument and is good to go:

userdata = {"firstname": "John", "lastname": "Doe", "password": "jdoe123"}
resp = requests.post('http://www.mywebsite.com/user', data=userdata)

Plus it even has a built in JSON decoder (again, I know json.loads() isn't a lot more to write, but this sure is convenient):

resp.json()

Or if your response data is just text, use:

resp.text

This is just the tip of the iceberg. This is the list of features from the requests site:

• International Domains and URLs
• Keep-Alive & Connection Pooling
• Sessions with Cookie Persistence
• Browser-style SSL Verification
• Basic/Digest Authentication
• Elegant Key/Value Cookies
• Automatic Decompression
• Unicode Response Bodies
• Multipart File Uploads
• Connection Timeouts
• .netrc support
• List item
• Python 2.6—3.4
• Thread-safe.

I had a scenario, and this one helped me

JObject objParserd = JObject.Parse(jsonString);

JObject arrayObject1 = (JObject)objParserd["d"];

D myOutput= JsonConvert.DeserializeObject<D>(arrayObject1.ToString());

What it is: A class for which there is just one, persistent instance across the lifetime of an application. See Singleton Pattern.

When you should use it: As little as possible. Only when you are absolutely certain that you need it. I'm reluctant to say "never", but there is usually a better alternative, such as Dependency Injection or simply a static class.

You can also use the provided CLI tool mysqlcheck to run the optimizations. It's got a ton of switches but at its most basic you just pass in the database, username, and password.

Adding this to cron or the Windows Scheduler can make this an automated process. (MariaDB but basically the same thing.)

According to Cormen et al. Introduction to Algorithms (Appendix B.5.3), the depth of a node X in a tree T is defined as the length of the simple path (number of edges) from the root node of T to X. The height of a node Y is the number of edges on the longest downward simple path from Y to a leaf. The height of a tree is defined as the height of its root node.

Note that a simple path is a path without repeat vertices.

The height of a tree is equal to the max depth of a tree. The depth of a node and the height of a node are not necessarily equal. See Figure B.6 of the 3rd Edition of Cormen et al. for an illustration of these concepts.

I have sometimes seen problems asking one to count nodes (vertices) instead of edges, so ask for clarification if you're not sure you should count nodes or edges during an exam or a job interview.

Considering this as a general programming problem, some possible causes are:

• The service could be temporarily broken

• You could have a problem with a firewall. These could be local or they could be implemented by your ISPs.

• Your proxy HTTP settings (if you need one) could be incorrect. This Answer explains how to adjust the Eclipse-internal proxy settings ... if that is where the problem lies.

• It is possible that your access may be blocked by over-active antivirus software.

• The service could have blacklisted some net range and your hosts IP address is "collateral damage".

Try connecting to that URL with a web browser to try to see if it is just Eclipse that is affected ... or a broader problem.

Considering this in the context of the Eclipse Marketplace service, first address any local proxy / firewall / AV issues, if they apply. If that doesn't help, the best thing that you can do is to be patient.

• It has been observed that the Eclipse Marketplace service does sometimes go down. It doesn't happen often, and when it does happen the problem does get fixed relatively quickly. (Hours, not days ...)

• I can't find a "service status" page or feed or similar for the Eclipse services. (If you know of one, please add it as a comment below.)

• There may be an "outage" notice on the Eclipse front page. Check for that.

• Try to connect to the service URL (refer to the exception message!) using a web browser and/or from other locations. If you succeed, the real problem may be a networking issue at your end.

• If you feel the need to complain about Eclipse's services, please don't do it here!! (It is off topic.)

Use:

ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
error_reporting(E_ALL);

This is the best way to write it, but a syntax error gives blank output, so use the console to check for syntax errors. The best way to debug PHP code is to use the console; run the following:

php -l phpfilename.php

Not in Linux at the moment, so can't double check, but I think it's:

rpm -ql ffmpeg

That should list all the files installed as part of the ffmpeg package.

Whenever you access an Object (not being a String) in a String context then the toString() is called under the covers by the compiler.

This is why

Map map = new HashMap();
System.out.println("map=" + map);

works, and by overriding the standard toString() from Object in your own classes, you can make your objects useful in String contexts too.

(and consider it a black box! Never, ever use the contents for anything else than presenting to a human)

Another option, for incrementing the versionCode and the versionName, is using a timestamp.

defaultConfig {
   versionName "${getVersionNameTimestamp()}"
   versionCode getVersionCodeTimestamp()
}


def getVersionNameTimestamp() {
    return new Date().format('yy.MM.ddHHmm')
}

def getVersionCodeTimestamp() {
    def date = new Date()
    def formattedDate = date.format('yyMMddHHmm')
    def code = formattedDate.toInteger()
    println sprintf("VersionCode: %d", code)
    return code
}

Starting on January,1 2022 formattedDate = date.format('yyMMddHHmm') exceeds the capacity of Integers

For everyone who is stuck with .NET 2.0, like me, try the following way (applicable to the example in the OP):

ConfigItemList.ConvertAll<string>(delegate (ConfigItemType ci) 
{ 
   return ci.Name; 
}).ToArray();

where ConfigItemList is your list variable.

The target "all" is an example of a dummy target - there is nothing on disk called "all". This means that when you do a "make all", make always thinks that it needs to build it, and so executes all the commands for that target. Those commands will typically be ones that build all the end-products that the makefile knows about, but it could do anything.

Other examples of dummy targets are "clean" and "install", and they work in the same way.

If you haven't read it yet, you should read the GNU Make Manual, which is also an excellent tutorial.

Inspired by @pixelbeat's answer, here's a horizontal bar brought to existence by tput, slight misuse of printf padding/filling and tr

Multithreading Multithreading extends the idea of multitasking into applications, so you can subdivide specific operations within a single application into individual threads.

.gitignore

is a text file comprising a list of files in your directory that git will ignore or not add/update in the repository.

.gitkeep

Since Git removes or doesn't add empty directories to a repository, .gitkeep is sort of a hack (I don't think it's officially named as a part of Git) to keep empty directories in the repository.

Just do a touch /path/to/emptydirectory/.gitkeep to add the file, and Git will now be able to maintain this directory in the repository.

The class.__stuff naming convention lets the programmer know he isn't meant to access __stuff from outside. The name mangling makes it unlikely anyone will do it by accident.

True, you still can work around this, it's even easier than in other languages (which BTW also let you do this), but no Python programmer would do this if he cares about encapsulation.

If you are trying to serve an HTML file which ALREADY has all it's content inside it, then it does not need to be 'rendered', it just needs to be 'served'. Rendering is when you have the server update or inject content before the page is sent to the browser, and it requires additional dependencies like ejs, as the other answers show.

If you simply want to direct the browser to a file based on their request, you should use res.sendFile() like this:

const express = require('express');
const app = express();
var port = process.env.PORT || 3000; //Whichever port you want to run on
app.use(express.static('./folder_with_html')); //This ensures local references to cs and js files work

app.get('/', (req, res) => {
  res.sendFile(__dirname + '/folder_with_html/index.html');
});

app.listen(port, () => console.log("lifted app; listening on port " + port));

This way you don't need additional dependencies besides express. If you just want to have the server send your already created html files, the above is a very lightweight way to do so.

I've found out the solution! Thanks to Firebug ;)

//"markers" is an array that I declared which contains all the marker of the map

Here is a jQuery function I wrote that helps me position elements.

Here is an example usage:

$(document).ready(function() {
  $('#el1').position('#el2', {
    anchor: ['br', 'tr'],
    offset: [-5, 5]
  });
});

The code above aligns the bottom-right of #el1 with the top-right of #el2. ['cc', 'cc'] would center #el1 in #el2. Make sure that #el1 has the css of position: absolute and z-index: 10000 (or some really large number) to keep it on top.

The offset option allows you to nudge the coordinates by a specified number of pixels.

The source code is below:

jQuery.fn.getBox = function() {
  return {
    left: $(this).offset().left,
    top: $(this).offset().top,
    width: $(this).outerWidth(),
    height: $(this).outerHeight()
  };
}

jQuery.fn.position = function(target, options) {
  var anchorOffsets = {t: 0, l: 0, c: 0.5, b: 1, r: 1};
  var defaults = {
    anchor: ['tl', 'tl'],
    animate: false,
    offset: [0, 0]
  };
  options = $.extend(defaults, options);

  var targetBox = $(target).getBox();
  var sourceBox = $(this).getBox();

  //origin is at the top-left of the target element
  var left = targetBox.left;
  var top = targetBox.top;

  //alignment with respect to source
  top -= anchorOffsets[options.anchor[0].charAt(0)] * sourceBox.height;
  left -= anchorOffsets[options.anchor[0].charAt(1)] * sourceBox.width;

  //alignment with respect to target
  top += anchorOffsets[options.anchor[1].charAt(0)] * targetBox.height;
  left += anchorOffsets[options.anchor[1].charAt(1)] * targetBox.width;

  //add offset to final coordinates
  left += options.offset[0];
  top += options.offset[1];

  $(this).css({
    left: left + 'px',
    top: top + 'px'
  });

}

I'm way late here, but after reading @Greg Pettit's answer and a couple of blogs or other SO questions I unfortunately can't remember I decided to just make a couple of dataTables plugins to deal with this.

I put them on bitbucket in a Mercurial repo. I follwed the fnSetFilteringDelay plugin and just changed the comments and code inside, as I've never made a plugin for anything before. I made 2, and feel free to use them, contribute to them, or provide suggestions.

• dataTables.TruncateCells - truncates each cell in a column down to a set number of characters, replacing the last 3 with an ellipses, and puts the full pre-truncated text in the cell's title attributed.

• dataTables.BreakCellText - attempts to insert a break character every X, user defined, characters in each cell in the column. There are quirks regarding cells that contain both spaces and hyphens, you can get some weird looking results (like a couple of characters straggling after the last inserted
  character). Maybe someone can make that more robust, or you can just fiddle with the breakPos for the column to make it look alright with your data.

The following solution makes use of jquery. Let's assume you have a checkbox with id of checkboxId.

const checkbox = $("#checkboxId");

checkbox.change(function(event) {
    var checkbox = event.target;
    if (checkbox.checked) {
        //Checkbox has been checked
    } else {
        //Checkbox has been unchecked
    }
});

There are two way to disable IOS Simulator internet:

• Unplug your network connection
• Turn Wi-Fi off

It's the simplest way

Rubygems >= 2.1.0

gem uninstall -aIx

a removes all versions
I ignores dependencies
x includes executables

Rubgems < 2.1.0

for i in `gem list --no-versions`; do gem uninstall -aIx $i; done

It can be used for sorting, and 0 means "equal" while -1, and 1 means "less" and "more (greater)".

Any return value that is less than 0 means that left operand is lesser, and if value is bigger than 0 then left operand is bigger.

You can use:

print (1==2 and "only if condition true" or "in case condition is false")

Just as well you can keep going like:

print 1==2 and "aa" or ((2==3) and "bb" or "cc")

Real world example:

>>> print "%d item%s found." % (count, (count>1 and 's' or ''))
1 item found.
>>> count = 2
>>> print "%d item%s found." % (count, (count>1 and 's' or ''))
2 items found.

Look at the ScriptManager.RegisterStartupScript method if you're using a ScriptManager or any Ajax controls/asynchronous postbacks.

Edit:

Actually, the function you want is probably ScriptManager.RegisterClientScriptBlock

Tomalak's answer worked great for me (+1)

I only needed to make alter it slightly for my purposes, and I didn't need a password - it's for corporate domain:

Option Explicit
Dim l: l = "Z:"
Dim s: s = "\\10.10.10.1\share"
Dim Network: Set Network = CreateObject("WScript.Network")
Dim CheckDrive: Set CheckDrive = Network.EnumNetworkDrives()
Dim DriveExists: DriveExists = False
Dim i

For i = 0 to CheckDrive.Count - 1
  If CheckDrive.Item(i) = l Then
    DriveExists = True
  End If
Next

If DriveExists = False Then
  Network.MapNetworkDrive l, s, False
Else
  MsgBox l + " Drive already mapped"
End If

Or if you want to disconnect the drive:

For i = 0 to CheckDrive.Count - 1
  If CheckDrive.Item(i) = l Then 
    WshNetwork.RemoveNetworkDrive CheckDrive.Item(i)
  End If
Next

In a thread on comp.lang.java.help, Hunter Gratzner gives some arguments against the presence of a Pair construct in Java. The main argument is that a class Pair doesn't convey any semantics about the relationship between the two values (how do you know what "first" and "second" mean ?).

A better practice is to write a very simple class, like the one Mike proposed, for each application you would have made of the Pair class. Map.Entry is an example of a pair that carry its meaning in its name.

To sum up, in my opinion it is better to have a class Position(x,y), a class Range(begin,end) and a class Entry(key,value) rather than a generic Pair(first,second) that doesn't tell me anything about what it's supposed to do.

itemgetter (see other answers) is (as I know) more efficient for large dictionaries but for the common case, I believe that d.get wins. And it does not require an extra import.

>>> d = {"aa": 3, "bb": 4, "cc": 2, "dd": 1}
>>> for k in sorted(d, key=d.get, reverse=True):
...     k, d[k]
...
('bb', 4)
('aa', 3)
('cc', 2)
('dd', 1)

Note that alternatively you can set d.__getitem__ as key function which may provide a small performance boost over d.get.

The testing suite doesn't make an attempt at using the imported timeit so it's hard to tell what the intent was. Nonetheless, this is a canonical answer so a complete example of timeit seems in order, elaborating on Martijn's answer.

The docs for timeit offer many examples and flags worth checking out. The basic usage on the command line is:

$ python -mtimeit "all(True for _ in range(1000))"
2000 loops, best of 5: 161 usec per loop
$ python -mtimeit "all([True for _ in range(1000)])"
2000 loops, best of 5: 116 usec per loop

Run with -h to see all options. Python MOTW has a great section on timeit that shows how to run modules via import and multiline code strings from the command line.

In script form, I typically use it like this:

import argparse
import copy
import dis
import inspect
import random
import sys
import timeit

def test_slice(L):
    L[:]

def test_copy(L):
    L.copy()

def test_deepcopy(L):
    copy.deepcopy(L)

if __name__ == "__main__":
    parser = argparse.ArgumentParser()
    parser.add_argument("--n", type=int, default=10 ** 5)
    parser.add_argument("--trials", type=int, default=100)
    parser.add_argument("--dis", action="store_true")
    args = parser.parse_args()
    n = args.n
    trials = args.trials
    namespace = dict(L = random.sample(range(n), k=n))
    funcs_to_test = [x for x in locals().values() 
                     if callable(x) and x.__module__ == __name__]
    print(f"{'-' * 30}\nn = {n}, {trials} trials\n{'-' * 30}\n")

    for func in funcs_to_test:
        fname = func.__name__
        fargs = ", ".join(inspect.signature(func).parameters)
        stmt = f"{fname}({fargs})"
        setup = f"from __main__ import {fname}"
        time = timeit.timeit(stmt, setup, number=trials, globals=namespace)
        print(inspect.getsource(globals().get(fname)))

        if args.dis:
            dis.dis(globals().get(fname))

        print(f"time (s) => {time}\n{'-' * 30}\n")

You can pretty easily drop in the functions and arguments you need. Use caution when using impure functions and take care of state.

Sample output:

$ python benchmark.py --n 10000
------------------------------
n = 10000, 100 trials
------------------------------

def test_slice(L):
    L[:]

time (s) => 0.015502399999999972
------------------------------

def test_copy(L):
    L.copy()

time (s) => 0.01651419999999998
------------------------------

def test_deepcopy(L):
    copy.deepcopy(L)

time (s) => 2.136012
------------------------------

To make the query run faster in big tables where not every line needs to be updated, you can also choose to only update rows that will be modified:

UPDATE dbo.xxx
SET Value = REPLACE(Value, '123', '')
WHERE ID <= 4
AND Value LIKE '%123%'

When going the other way (hasMany):

User::with(array('post'=>function($query){
    $query->select('id','user_id');
}))->get();

Don't forget to include the foreign key (assuming it is user_id in this example) to resolve the relationship, otherwise you'll get zero results for your relation.
