getItemViewType(int position) is the key

In my opinion,the starting point to create this kind of recyclerView is the knowledge of this method. Since this method is optional to override therefore it is not visible in RecylerView class by default which in turn makes many developers(including me) wonder where to begin. Once you know that this method exists, creating such RecyclerView would be a cakewalk.

How to do it ?

You can create a RecyclerView with any number of different Views(ViewHolders). But for better readability lets take an example of RecyclerView with two Viewholders.
Remember these 3 simple steps and you will be good to go.

• Override public int getItemViewType(int position)
• Return different ViewHolders based on the ViewType in onCreateViewHolder() method

• Populate View based on the itemViewType in onBindViewHolder() method

  Here is a code snippet for you

  public class YourListAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder> {
  
      private static final int LAYOUT_ONE= 0;
      private static final int LAYOUT_TWO= 1;
  
      @Override
      public int getItemViewType(int position)
      {
          if(position==0)
             return LAYOUT_ONE;
          else
             return LAYOUT_TWO;
      }
  
      @Override
      public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
  
          View view =null;
          RecyclerView.ViewHolder viewHolder = null;
  
          if(viewType==LAYOUT_ONE)
          {
             view = LayoutInflater.from(parent.getContext()).inflate(R.layout.one,parent,false);
             viewHolder = new ViewHolderOne(view);
          }
          else
          {
             view = LayoutInflater.from(parent.getContext()).inflate(R.layout.two,parent,false);
             viewHolder= new ViewHolderTwo(view);
          }
  
          return viewHolder;
      }
  
      @Override
      public void onBindViewHolder(RecyclerView.ViewHolder holder, final int position) {
  
         if(holder.getItemViewType()== LAYOUT_ONE)
         {
             // Typecast Viewholder 
             // Set Viewholder properties 
             // Add any click listener if any 
         }
         else {
  
             ViewHolderOne vaultItemHolder = (ViewHolderOne) holder;
             vaultItemHolder.name.setText(displayText);
             vaultItemHolder.name.setOnClickListener(new View.OnClickListener() {
                 @Override
                 public void onClick(View v) {
                     .......
                 }
             });
  
         }
  
     }
  
     /****************  VIEW HOLDER 1 ******************//
  
     public class ViewHolderOne extends RecyclerView.ViewHolder {
  
         public TextView name;
  
         public ViewHolderOne(View itemView) {
         super(itemView);
         name = (TextView)itemView.findViewById(R.id.displayName);
         }
     }
  
  
    //****************  VIEW HOLDER 2 ******************//
  
    public class ViewHolderTwo extends RecyclerView.ViewHolder{
  
         public ViewHolderTwo(View itemView) {
         super(itemView);
  
             ..... Do something
         }
    }
  }
  

GitHub Code:

Here is a project where I have implemented a RecyclerView with multiple ViewHolders.

Caveat: I'm running Ubuntu

sudo service --status-all

you can get a list of all running services by typing this command,

If you're running Tomcat as a service it will showes up as ("tomcat"), so run :

sudo service tomcat7 stop

(tomcat7 or 8 or depending to the name that you have in the list of running services )

else and if you are using apache tomcat you will see ("apache2") showing up with the list of services then run :

sudo service apache2 stop

SELECT * FROM employees WHERE name NOT IN (SELECT name FROM eotm_dyn)

OR

SELECT * FROM employees WHERE NOT EXISTS (SELECT * FROM eotm_dyn WHERE eotm_dyn.name = employees.name)

OR

SELECT * FROM employees LEFT OUTER JOIN eotm_dyn ON eotm_dyn.name = employees.name WHERE eotm_dyn IS NULL

For finding value use below

if let a = companies["AAPL"] {
   // a is the value
}

For traversing through the dictionary

for (key, value) in companies {
    print(key,"---", value)
}

Finally for searching key by value you firstly add the extension

extension Dictionary where Value: Equatable {
    func findKey(forValue val: Value) -> Key? {
        return first(where: { $1 == val })?.key
    }
}

Then just call

companies.findKey(val : "Apple Inc")

It is the NextStep (= NS) heritage. NeXT was the computer company that Steve Jobs formed after he quit Apple in 1985, and NextStep was it's operating system (UNIX based) together with the Obj-C language and runtime. Together with it's libraries and tools, NextStep was later renamed OpenStep (which was also the name on an API that NeXT developed together with Sun), which in turn later became Cocoa.

These different names are actually quite confusing (especially since some of the names differs only in which characters are upper or lower case..), try this for an explanation:

What worked for me is I:

1. Went to about:config.
2. Typed "security" in the search box.
3. Set all of the returned entries to their defaults.
4. Typed "ssl" in the search box.
5. Set all of the returned results to their defaults.
6. Enabled ssl2.
7. Disabled ssl3.
8. Restarted Firefox.

Note about restarting Firefox: When I do start it very soon after closing it, it often has a file access problem, which requires me to delete places.sqlite and places.sqlite-journal in C:\WINDOWS\Application Data\Mozilla\Firefox\Profiles\n18091xv.default. This causes me to lose my history, plus bookmarks have to be restored from a backup each time this happens. I wait from five to ten minutes or more to avoid this hassle.

Command line only without sdkmanager (for advanced users / CI):

You can find the download links for all individual packages, including various revisions, in the repository XML file: https://dl.google.com/android/repository/repository-12.xml

(where 12 is the version of the repository index and will increase in the future).

All <sdk:url> values are relative to https://dl.google.com/android/repository, so

<sdk:url>platform-27_r03.zip</sdk:url>

can be downloaded at https://dl.google.com/android/repository/platform-27_r03.zip

Similar summary XML files exist for system images as well:

• (default) https://dl.google.com/android/repository/sys-img/android/sys-img.xml
• (google_apis) https://dl.google.com/android/repository/sys-img/google_apis/sys-img.xml

There are several approaches to customize the error handling behavior with JAX-RS. Here are three of the easier ways.

The first approach is to create an Exception class that extends WebApplicationException.

Example:

public class NotAuthorizedException extends WebApplicationException {
     public NotAuthorizedException(String message) {
         super(Response.status(Response.Status.UNAUTHORIZED)
             .entity(message).type(MediaType.TEXT_PLAIN).build());
     }
}

And to throw this newly create Exception you simply:

@Path("accounts/{accountId}/")
    public Item getItem(@PathParam("accountId") String accountId) {
       // An unauthorized user tries to enter
       throw new NotAuthorizedException("You Don't Have Permission");
}

Notice, you don't need to declare the exception in a throws clause because WebApplicationException is a runtime Exception. This will return a 401 response to the client.

The second and easier approach is to simply construct an instance of the WebApplicationException directly in your code. This approach works as long as you don't have to implement your own application Exceptions.

Example:

@Path("accounts/{accountId}/")
public Item getItem(@PathParam("accountId") String accountId) {
   // An unauthorized user tries to enter
   throw new WebApplicationException(Response.Status.UNAUTHORIZED);
}

This code too returns a 401 to the client.

Of course, this is just a simple example. You can make the Exception much more complex if necessary, and you can generate what ever http response code you need to.

One other approach is to wrap an existing Exception, perhaps an ObjectNotFoundException with an small wrapper class that implements the ExceptionMapper interface annotated with a @Provider annotation. This tells the JAX-RS runtime, that if the wrapped Exception is raised, return the response code defined in the ExceptionMapper.

In ASCII the upper and lower case alphabet is 0x20 (in ASCII 0x20 is space ' ') apart from each other, so this is another way to do it.

int lower(int a) 
{
    return a | ' ';  
}

const state.contactList = [{
    name: 'jane',
    email: '[email protected]'
  },{},{},...]

const fileredArray = state.contactsList.filter((contactItem) => {
  const regex = new RegExp(`${action.payload}`, 'gi');
  return contactItem.nameProperty.match(regex) || 
    contactItem.emailProperty.match(regex);
});


// contactList: all the contacts stored in state
// action.payload: whatever typed in search field

Note that if you care about speed and do not need to worry about singularities, solve() should be preferred to ginv() because it is much faster, as you can check:

require(MASS)
mat <- matrix(rnorm(1e6),nrow=1e3,ncol=1e3)

t0 <- proc.time()
inv0 <- ginv(mat)
proc.time() - t0 

t1 <- proc.time()
inv1 <- solve(mat)
proc.time() - t1 

IF YOU HAVE A STRING WITH HTML CODE INSIDE YOU CAN USE:

extension String {
var utfData: Data? {
        return self.data(using: .utf8)
    }

    var htmlAttributedString: NSAttributedString? {
        guard let data = self.utfData else {
            return nil
        }
        do {
            return try NSAttributedString(data: data,
                                          options: [
                                            .documentType: NSAttributedString.DocumentType.html,
                                            .characterEncoding: String.Encoding.utf8.rawValue
                ], documentAttributes: nil)
        } catch {
            print(error.localizedDescription)
            return nil
        }
    }

    var htmlString: String {
        return htmlAttributedString?.string ?? self 
    }
}

AND IN YOUR CODE YOU USE:

label.text = "something".htmlString

The way to do this has changed in mock 0.7.0 which finally supports mocking the python protocol methods (magic methods), particularly using the MagicMock:

http://www.voidspace.org.uk/python/mock/magicmock.html

An example of mocking open as a context manager (from the examples page in the mock documentation):

>>> open_name = '%s.open' % __name__
>>> with patch(open_name, create=True) as mock_open:
...     mock_open.return_value = MagicMock(spec=file)
...
...     with open('/some/path', 'w') as f:
...         f.write('something')
...
<mock.Mock object at 0x...>
>>> file_handle = mock_open.return_value.__enter__.return_value
>>> file_handle.write.assert_called_with('something')

Generating all the indices of a sequence is generally a bad idea, as it might take a lot of time, especially if the ratio of the numbers to be chosen to MAX is low (the complexity becomes dominated by O(MAX)). This gets worse if the ratio of the numbers to be chosen to MAX approaches one, as then removing the chosen indices from the sequence of all also becomes expensive (we approach O(MAX^2/2)). But for small numbers, this generally works well and is not particularly error-prone.

Filtering the generated indices by using a collection is also a bad idea, as some time is spent in inserting the indices into the sequence, and progress is not guaranteed as the same random number can be drawn several times (but for large enough MAX it is unlikely). This could be close to complexity
O(k n log^2(n)/2), ignoring the duplicates and assuming the collection uses a tree for efficient lookup (but with a significant constant cost k of allocating the tree nodes and possibly having to rebalance).

Another option is to generate the random values uniquely from the beginning, guaranteeing progress is being made. That means in the first round, a random index in [0, MAX] is generated:

items i0 i1 i2 i3 i4 i5 i6 (total 7 items)
idx 0       ^^             (index 2)

In the second round, only [0, MAX - 1] is generated (as one item was already selected):

items i0 i1    i3 i4 i5 i6 (total 6 items)
idx 1          ^^          (index 2 out of these 6, but 3 out of the original 7)

The values of the indices then need to be adjusted: if the second index falls in the second half of the sequence (after the first index), it needs to be incremented to account for the gap. We can implement this as a loop, allowing us to select arbitrary number of unique items.

For short sequences, this is quite fast O(n^2/2) algorithm:

void RandomUniqueSequence(std::vector<int> &rand_num,
    const size_t n_select_num, const size_t n_item_num)
{
    assert(n_select_num <= n_item_num);

    rand_num.clear(); // !!

    // b1: 3187.000 msec (the fastest)
    // b2: 3734.000 msec
    for(size_t i = 0; i < n_select_num; ++ i) {
        int n = n_Rand(n_item_num - i - 1);
        // get a random number

        size_t n_where = i;
        for(size_t j = 0; j < i; ++ j) {
            if(n + j < rand_num[j]) {
                n_where = j;
                break;
            }
        }
        // see where it should be inserted

        rand_num.insert(rand_num.begin() + n_where, 1, n + n_where);
        // insert it in the list, maintain a sorted sequence
    }
    // tier 1 - use comparison with offset instead of increment
}

Where n_select_num is your 5 and n_number_num is your MAX. The n_Rand(x) returns random integers in [0, x] (inclusive). This can be made a bit faster if selecting a lot of items (e.g. not 5 but 500) by using binary search to find the insertion point. To do that, we need to make sure that we meet the requirements.

We will do binary search with the comparison n + j < rand_num[j] which is the same as
n < rand_num[j] - j. We need to show that rand_num[j] - j is still a sorted sequence for a sorted sequence rand_num[j]. This is fortunately easily shown, as the lowest distance between two elements of the original rand_num is one (the generated numbers are unique, so there is always difference of at least 1). At the same time, if we subtract the indices j from all the elements
rand_num[j], the differences in index are exactly 1. So in the "worst" case, we get a constant sequence - but never decreasing. The binary search can therefore be used, yielding O(n log(n)) algorithm:

struct TNeedle { // in the comparison operator we need to make clear which argument is the needle and which is already in the list; we do that using the type system.
    int n;

    TNeedle(int _n)
        :n(_n)
    {}
};

class CCompareWithOffset { // custom comparison "n < rand_num[j] - j"
protected:
    std::vector<int>::iterator m_p_begin_it;

public:
    CCompareWithOffset(std::vector<int>::iterator p_begin_it)
        :m_p_begin_it(p_begin_it)
    {}

    bool operator ()(const int &r_value, TNeedle n) const
    {
        size_t n_index = &r_value - &*m_p_begin_it;
        // calculate index in the array

        return r_value < n.n + n_index; // or r_value - n_index < n.n
    }

    bool operator ()(TNeedle n, const int &r_value) const
    {
        size_t n_index = &r_value - &*m_p_begin_it;
        // calculate index in the array

        return n.n + n_index < r_value; // or n.n < r_value - n_index
    }
};

And finally:

void RandomUniqueSequence(std::vector<int> &rand_num,
    const size_t n_select_num, const size_t n_item_num)
{
    assert(n_select_num <= n_item_num);

    rand_num.clear(); // !!

    // b1: 3578.000 msec
    // b2: 1703.000 msec (the fastest)
    for(size_t i = 0; i < n_select_num; ++ i) {
        int n = n_Rand(n_item_num - i - 1);
        // get a random number

        std::vector<int>::iterator p_where_it = std::upper_bound(rand_num.begin(), rand_num.end(),
            TNeedle(n), CCompareWithOffset(rand_num.begin()));
        // see where it should be inserted

        rand_num.insert(p_where_it, 1, n + p_where_it - rand_num.begin());
        // insert it in the list, maintain a sorted sequence
    }
    // tier 4 - use binary search
}

I have tested this on three benchmarks. First, 3 numbers were chosen out of 7 items, and a histogram of the items chosen was accumulated over 10,000 runs:

4265 4229 4351 4267 4267 4364 4257

This shows that each of the 7 items was chosen approximately the same number of times, and there is no apparent bias caused by the algorithm. All the sequences were also checked for correctness (uniqueness of contents).

The second benchmark involved choosing 7 numbers out of 5000 items. The time of several versions of the algorithm was accumulated over 10,000,000 runs. The results are denoted in comments in the code as b1. The simple version of the algorithm is slightly faster.

The third benchmark involved choosing 700 numbers out of 5000 items. The time of several versions of the algorithm was again accumulated, this time over 10,000 runs. The results are denoted in comments in the code as b2. The binary search version of the algorithm is now more than two times faster than the simple one.

The second method starts being faster for choosing more than cca 75 items on my machine (note that the complexity of either algorithm does not depend on the number of items, MAX).

It is worth mentioning that the above algorithms generate the random numbers in ascending order. But it would be simple to add another array to which the numbers would be saved in the order in which they were generated, and returning that instead (at negligible additional cost O(n)). It is not necessary to shuffle the output: that would be much slower.

Note that the sources are in C++, I don't have Java on my machine, but the concept should be clear.

EDIT:

For amusement, I have also implemented the approach that generates a list with all the indices
0 .. MAX, chooses them randomly and removes them from the list to guarantee uniqueness. Since I've chosen quite high MAX (5000), the performance is catastrophic:

// b1: 519515.000 msec
// b2: 20312.000 msec
std::vector<int> all_numbers(n_item_num);
std::iota(all_numbers.begin(), all_numbers.end(), 0);
// generate all the numbers

for(size_t i = 0; i < n_number_num; ++ i) {
    assert(all_numbers.size() == n_item_num - i);
    int n = n_Rand(n_item_num - i - 1);
    // get a random number

    rand_num.push_back(all_numbers[n]); // put it in the output list
    all_numbers.erase(all_numbers.begin() + n); // erase it from the input
}
// generate random numbers

I have also implemented the approach with a set (a C++ collection), which actually comes second on benchmark b2, being only about 50% slower than the approach with the binary search. That is understandable, as the set uses a binary tree, where the insertion cost is similar to binary search. The only difference is the chance of getting duplicate items, which slows down the progress.

// b1: 20250.000 msec
// b2: 2296.000 msec
std::set<int> numbers;
while(numbers.size() < n_number_num)
    numbers.insert(n_Rand(n_item_num - 1)); // might have duplicates here
// generate unique random numbers

rand_num.resize(numbers.size());
std::copy(numbers.begin(), numbers.end(), rand_num.begin());
// copy the numbers from a set to a vector

Full source code is here.

For concatenating selectors together when nesting, you need to use the parent selector (&):

.class {
    margin:20px;
    &:hover {
        color:yellow;
    }
}

INSERT INTO prices (group, id, price)
  SELECT 7, articleId, 1.50 FROM article WHERE name LIKE 'ABC%'

Find combine result for Datatype and Length and is nullable in form of "NULL" and "Not null" Use below query.

SELECT c.name AS 'Column Name',
       t.name + '(' + cast(c.max_length as varchar(50)) + ')' As 'DataType',
       case 
         WHEN  c.is_nullable = 0 then 'null' else 'not null'
         END AS 'Constraint'
  FROM sys.columns c
  JOIN sys.types t
    ON c.user_type_id = t.user_type_id
 WHERE c.object_id    = Object_id('TableName')

you will find result as shown below.

Thank you.

Having just struggled with this - I'll explain my situation.

I have my tabs within a bootstrap modal and set the following on load (pre the modal being triggered):

$('#subMenu li:first-child a').tab('show');

Whilst the tab was selected the actual pane wasn't visible. As such you need to add active class to the pane as well:

$('#profile').addClass('active');

In my case the pane had #profile (but this could have easily been .pane:first-child) which then displayed the correct pane.

There is no "correct" way to store a 64-bit pointer in an 32-bit integer. The problem is not with casting, but with the target type loosing half of the pointer. The 32 remaining bits stored inside int are insufficient to reconstruct a pointer to the thread function. Most answers just try to extract 32 useless bits out of the argument.

As Ferruccio said, int must be replaced with intptr_t to make the program meaningful.

One additional thing I would like to mention that some of the answers may have missed is the downside to having both ETags and Expires/Cache-control in your headers.

Depending on your needs it may just add extra bytes in your headers which may increase packets which means more TCP overhead. Again, you should see if the overhead of having both things in your headers is necessary or will it just add extra weight in your requests which reduces performance.

You can read more about it on this excellent blog post by Kyle Simpson: http://calendar.perfplanet.com/2010/bloated-request-response-headers/

As soon as python requests will be merged with SOCKS5 pull request it will do as simple as using proxies dictionary:

#proxy
        # SOCKS5 proxy for HTTP/HTTPS
        proxies = {
            'http' : "socks5://myproxy:9191",
            'https' : "socks5://myproxy:9191"
        }

        #headers
        headers = {

        }

        url='http://icanhazip.com/'
        res = requests.get(url, headers=headers, proxies=proxies)

See SOCKS Proxy Support

Another options, in case that you cannot wait request to be ready, when you cannot use requesocks - like on GoogleAppEngine due to the lack of pwd built-in module, is to use PySocks that was mentioned above:

1. Grab the socks.py file from the repo and put a copy in your root folder;
2. Add import socks and import socket

At this point configure and bind the socket before using with urllib2 - in the following example:

import urllib2
import socket
import socks

socks.set_default_proxy(socks.SOCKS5, "myprivateproxy.net",port=9050)
socket.socket = socks.socksocket
res=urllib2.urlopen(url).read()

This error occurred for me when a value was returned as -1.#IND due to a division by zero. More info on IEEE floating-point exceptions in C++ here on SO and by John Cook

For the one who has downvoted this answer (and did not specify why), the reason why this answer can be significant to some is that a division by zero will lead to an infinitely large number and thus a value that doesn't fit in an Int32 (or even Int64). So the error you receive will be the same (Arithmetic operation resulted in an overflow) but the reason is slightly different.

For those looking for an efficient method to convert an image file to a Base64 string without compression or converting the file to a bitmap first, you can instead encode the file as base64

val base64EncodedImage = FileInputStream(imageItem.localSrc).use {inputStream - >

Also it may cause some warnigs in logs like a Cglib2AopProxy Unable to proxy method. And many other reasons for this are described here Why always have single implementaion interfaces in service and dao layers?

A simple solution would be to iterate through the Controls list in a foreach loop. Something like this:

foreach (Control child in Controls)
{
    // Code that executes for each control.
}

So now you have your iterator, child, which is of type Control. Now do what you will with that, personally I found this in a project I did a while ago in which it added an event for this control, like this:

child.MouseDown += new MouseEventHandler(dragDown);

If you have a typescript file, you have to instruct the webpack to resolve them by using below code in webpack.config.js

module.exports={
   ...
   resolve:{
      extensions:['.ts','.tsx';]
   }
}

You can access mySQL in command line just by typing:

C:\www\mysql\bin> mysql -u root -p

After which you can type sql commands normally such as:

mysql> SHOW DATABASES;

Here, I am assuming you mySQL installation directory is C:\www\mysql.

Here's a different way of looking at it, and it's a simple one-liner:

int spaces = s.replaceAll("[^ ]", "").length();

This works by effectively removing all non-spaces then taking the length of what’s left (the spaces).

You might want to add a null check:

int spaces = s == null ? 0 : s.replaceAll("[^ ]", "").length();

Java 8 update

You can use a stream too:

int spaces = s.chars().filter(c -> c == (int)' ').count();

To select the item from the contextual menu, you have to just move your mouse positions with the use of Key down event like this:-

Actions action= new Actions(driver);
action.contextClick(productLink).sendKeys(Keys.ARROW_DOWN).sendKeys(Keys.ARROW_DOWN).sendKeys(Keys.RETURN).build().perform();

hope this will works for you. Have a great day :)

var idList=new int[]{1, 2, 3, 4};
var friendsToUpdate = await Context.Friends.Where(f => 
    idList.Contains(f.Id).ToListAsync();

foreach(var item in previousEReceipts)
{
  item.msgSentBy = "1234";
}

You can use foreach to update each element that meets your condition.

Here is an example in a more generic way:

var itemsToUpdate = await Context.friends.Where(f => f.Id == <someCondition>).ToListAsync();

foreach(var item in itemsToUpdate)
{
   item.property = updatedValue;
}
Context.SaveChanges()

In general you will most probably use async methods with await for db queries.

The Git GUI for Windows has a window-based application that allows you to paste in locations for ssh keys and repo url etc:

Another option to all of the good answers here is the npm package react-google-font-loader, found here.

The usage is simple:

import GoogleFontLoader from 'react-google-font-loader';

// Somewhere in your React tree:

<GoogleFontLoader
    fonts={[
        {
            font: 'Bungee Inline',
            weights: [400],
        },
    ]}
/>

Then you can just use the family name in your CSS:

body {
    font-family: 'Bungee Inline', cursive;
}

Disclaimer: I'm the author of the react-google-font-loader package.

May be:

ArrayList<ServiceModel> services = new ArrayList<>(parking.getServices());
intent.putExtra("servicios",services);

You can do this:

<div style="text-align: center">
    <a href="contact.html" class="button large hpbottom">Get Started</a>
</div>

A good idea is to set all of the "" (blank cells) to NA before any further analysis.

If you are reading your input from a file, it is a good choice to cast all "" to NAs:

foo <- read.table(file="Your_file.txt", na.strings=c("", "NA"), sep="\t") # if your file is tab delimited

If you have already your table loaded, you can act as follows:

foo[foo==""] <- NA

Then to keep only rows with no NA you may just use na.omit():

foo <- na.omit(foo)

Or to keep columns with no NA:

foo <- foo[, colSums(is.na(foo)) == 0] 

In Python self is the conventional name given to the first argument of instance methods of classes, which is always the instance the method was called on:

class A(object):
  def f(self):
    print self

a = A()
a.f()

Will give you something like

<__main__.A object at 0x02A9ACF0>

I've tried to make a synthesis of all solutions and created a [ButtenHandler] attribute that makes it easy to handle multiple buttons on a form.

I've described it on CodeProject Multiple parameterized (localizable) form buttons in ASP.NET MVC.

To handle the simple case of this button:

<button type="submit" name="AddDepartment">Add Department</button>

You'll have something like the following action method:

[ButtonHandler()]
public ActionResult AddDepartment(Company model)
{
    model.Departments.Add(new Department());
    return View(model);
}

Notice how the name of the button matches the name of the action method. The article also describes how to have buttons with values and buttons with indexes.

For windows, @shoaly parameters didn't completely work for me. I was getting this error:

NCAT DEBUG: Proxy returned status code 501.
Ncat: Proxy returned status code 501.
ssh_exchange_identification: Connection closed by remote host

I wanted to ssh to a REMOTESERVER and the SSH port had been closed in my network. I found two solutions but the second is better.

• To solve the problem using Ncat:

  1. I downloaded Tor Browser, run and wait to connect.
  2. I got Ncat from Nmap distribution and extracted ncat.exe into the current directory.

  3. SSH using Ncat as ProxyCommand in Git Bash with addition --proxy-type socks4 parameter:

     ssh -o "ProxyCommand=./ncat --proxy-type socks4 --proxy 127.0.0.1:9150 %h %p" USERNAME@REMOTESERVER
     

     Note that this implementation of Ncat does not support socks5.

• THE BETTER SOLUTION:

  1. Do the previous step 1.

  2. SSH using connect.c as ProxyCommand in Git Bash:

     ssh -o "ProxyCommand=connect -a none -S 127.0.0.1:9150 %h %p"
     

     Note that connect.c supports socks version 4/4a/5.

To use the proxy in git commands using ssh (for example while using GitHub) -- assuming you installed Git Bash in C:\Program Files\Git\ -- open ~/.ssh/config and add this entry:

host github.com
    user git
    hostname github.com
    port 22
    proxycommand "/c/Program Files/Git/mingw64/bin/connect.exe" -a none -S 127.0.0.1:9150 %h %p

Kenny is right, just want to clear some things out.

1. Create the file border.xml and put it in the folder res/drawable/

2. add the code

   <shape xmlns:android="http://schemas.android.com/apk/res/android"> 
      <stroke android:width="4dp" android:color="#FF00FF00" /> 
      <solid android:color="#ffffff" /> 
      <padding android:left="7dp" android:top="7dp" 
           android:right="7dp" android:bottom="0dp" /> 
      <corners android:radius="4dp" /> 
   </shape>
   

3. set back ground like android:background="@drawable/border" wherever you want the border

Mine first didn't work cause i put the border.xml in the wrong folder!

Depending on the sort order, you can do this :

    int[] array = new int[] { 3, 1, 4, 5, 2 };
    Array.Sort<int>(array,
                    new Comparison<int>(
                            (i1, i2) => i2.CompareTo(i1)
                    ));

... or this :

    int[] array = new int[] { 3, 1, 4, 5, 2 };
    Array.Sort<int>(array,
                    new Comparison<int>(
                            (i1, i2) => i1.CompareTo(i2)
                    ));

i1 and i2 are just reversed.

This worked for me.

look for this:

    DirectoryIndex index.php

replace with this:

    DirectoryIndex something.php index.php

Upload and refresh page. You will get a page error.

just change it back to:

    DirectoryIndex index.php

reupload and refresh page again.
I checked this on all of my devices and, it worked.

Try this:

^[-+]?(([0-8]\\d|\\d)(\\.\\d+)?|90(\\.0+)?)$,\s*^[-+]?((1[0-7]\\d(\\.\\d+)?)|(180(\\.0+)?)|(\\d\\d(\\.\\d+)?)|(\\d(\\.\\d+)?))$

Given it's a raw expression, you should use DB::raw() to set CURRENT_TIMESTAMP as a default value for a column:

$table->timestamp('created_at')->default(DB::raw('CURRENT_TIMESTAMP'));

This works flawlessly on every database driver.

New shortcut

As of Laravel 5.1.25 (see PR 10962 and commit 15c487fe) you can use the new useCurrent() column modifier method to set the CURRENT_TIMESTAMP as a default value for a column:

$table->timestamp('created_at')->useCurrent();

Back to the question, on MySQL you could also use the ON UPDATE clause through DB::raw():

$table->timestamp('updated_at')->default(DB::raw('CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP'));

Gotchas

• MySQL
  
  Starting with MySQL 5.7, 0000-00-00 00:00:00 is no longer considered a valid date. As documented at the Laravel 5.2 upgrade guide, all timestamp columns should receive a valid default value when you insert records into your database. You may use the useCurrent() column modifier (from Laravel 5.1.25 and above) in your migrations to default the timestamp columns to the current timestamps, or you may make the timestamps nullable() to allow null values.

• PostgreSQL & Laravel 4.x
  
  In Laravel 4.x versions, the PostgreSQL driver was using the default database precision to store timestamp values. When using the CURRENT_TIMESTAMP function on a column with a default precision, PostgreSQL generates a timestamp with the higher precision available, thus generating a timestamp with a fractional second part - see this SQL fiddle.

  This will led Carbon to fail parsing a timestamp since it won't be expecting microseconds being stored. To avoid this unexpected behavior breaking your application you have to explicitly give a zero precision to the CURRENT_TIMESTAMP function as below:

  $table->timestamp('created_at')->default(DB::raw('CURRENT_TIMESTAMP(0)'));
  

  Since Laravel 5.0, timestamp() columns has been changed to use a default precision of zero which avoids this.

  Thanks to @andrewhl for pointing out this issue in the comments.

To squabble about the performance of binary-trees is meaningless - they are not a data structure, but a family of data structures, all with different performance characteristics. While it is true that unbalanced binary trees perform much worse than self-balancing binary trees for searching, there are many binary trees (such as binary tries) for which "balancing" has no meaning.

Applications of binary trees

• Binary Search Tree - Used in many search applications where data is constantly entering/leaving, such as the map and set objects in many languages' libraries.
• Binary Space Partition - Used in almost every 3D video game to determine what objects need to be rendered.
• Binary Tries - Used in almost every high-bandwidth router for storing router-tables.
• Hash Trees - used in p2p programs and specialized image-signatures in which a hash needs to be verified, but the whole file is not available.
• Heaps - Used in implementing efficient priority-queues, which in turn are used for scheduling processes in many operating systems, Quality-of-Service in routers, and A* (path-finding algorithm used in AI applications, including robotics and video games). Also used in heap-sort.
• Huffman Coding Tree (Chip Uni) - used in compression algorithms, such as those used by the .jpeg and .mp3 file-formats.
• GGM Trees - Used in cryptographic applications to generate a tree of pseudo-random numbers.
• Syntax Tree - Constructed by compilers and (implicitly) calculators to parse expressions.
• Treap - Randomized data structure used in wireless networking and memory allocation.
• T-tree - Though most databases use some form of B-tree to store data on the drive, databases which keep all (most) their data in memory often use T-trees to do so.

The reason that binary trees are used more often than n-ary trees for searching is that n-ary trees are more complex, but usually provide no real speed advantage.

In a (balanced) binary tree with m nodes, moving from one level to the next requires one comparison, and there are log_2(m) levels, for a total of log_2(m) comparisons.

In contrast, an n-ary tree will require log_2(n) comparisons (using a binary search) to move to the next level. Since there are log_n(m) total levels, the search will require log_2(n)*log_n(m) = log_2(m) comparisons total. So, though n-ary trees are more complex, they provide no advantage in terms of total comparisons necessary.

(However, n-ary trees are still useful in niche-situations. The examples that come immediately to mind are quad-trees and other space-partitioning trees, where divisioning space using only two nodes per level would make the logic unnecessarily complex; and B-trees used in many databases, where the limiting factor is not how many comparisons are done at each level but how many nodes can be loaded from the hard-drive at once)

Newer versions of OpenSSL say BEGIN PRIVATE KEY because they contain the private key + an OID that identifies the key type (this is known as PKCS8 format). To get the old style key (known as either PKCS1 or traditional OpenSSL format) you can do this:

openssl rsa -in server.key -out server_new.key

Alternately, if you have a PKCS1 key and want PKCS8:

openssl pkcs8 -topk8 -nocrypt -in privkey.pem

It's perfectly possible to update multiple columns in the same statement, and in fact your code is doing it. So why does it seem that "INV_TOTAL is not updating, only the inv_discount"?

Because you're updating INV_TOTAL with INV_DISCOUNT, and the database is going to use the existing value of INV_DISCOUNT and not the one you change it to. So I'm afraid what you need to do is this:

UPDATE INVOICE
   SET INV_DISCOUNT = DISC1 * INV_SUBTOTAL
     , INV_TOTAL    = INV_SUBTOTAL - (DISC1 * INV_SUBTOTAL)     
WHERE INV_ID = I_INV_ID;

        

Perhaps that seems a bit clunky to you. It is, but the problem lies in your data model. Storing derivable values in the table, rather than deriving when needed, rarely leads to elegant SQL.

This will format column A as text, B as General, C as a number.

Sub formatColumns()
 Columns(1).NumberFormat = "@"
 Columns(2).NumberFormat = "General"
 Columns(3).NumberFormat = "0"
End Sub

Java 8+ version:

Files.createDirectories(Paths.get("/Your/Path/Here"));

The Files.createDirectories() creates a new directory and parent directories that do not exist. This method does not throw an exception if the directory already exists.

Not what OP asked, but for any soul that might be as well writing an userscript that goes through input fields and fills the required details. Nothing (fully) worked for me, but finally managed to get it done this way:

var el = $('#sp_formfield_fw_ip');
el.val("some value");
angular.element(el).triggerHandler('focus');
angular.element(el).triggerHandler('input');
angular.element(el).triggerHandler('change');
angular.element(el).triggerHandler('blur');

Open developer tools, and inspect input field for added events. There I found all of them (in my case): focus, input, change and blur.

You have to set the height for the parents (container and child) explicitly, here is another work-around (if you don't want to set that height explicitly):

.child {
  width: 30px;
  background-color: red;
  display: table-cell;
  vertical-align: top;
  position:relative;
}

.content {
  position:absolute;
  top:0;
  bottom:0;
  width:100%;
  background-color: blue;
}

Fiddle

The easiest cross browser solution for supporting parameters in setTimeout:

setTimeout(function() {
    postinsql(topicId);
}, 4000)

If you don't mind not supporting IE 9 and lower:

setTimeout(postinsql, 4000, topicId);

use fixed-bottom bootstrap class

<div id="footer" class="fixed-bottom w-100">

I would recommend not to use HTTP authentication with custom scheme names. If you feel that you have something of generic use, you can define a new scheme, though. See http://greenbytes.de/tech/webdav/draft-ietf-httpbis-p7-auth-latest.html#rfc.section.2.3 for details.

Your code below is zooming the map to fit the specified bounds:

addMarker(27.703402,85.311668,'New Road');
center = bounds.getCenter();
map.fitBounds(bounds);

If you only have 1 marker and add it to the bounds, that results in the closest zoom possible:

function addMarker(lat, lng, info) {
  var pt = new google.maps.LatLng(lat, lng);
  bounds.extend(pt);
}

If you keep track of the number of markers you have "added" to the map (or extended the bounds with), you can only call fitBounds if that number is greater than one. I usually push the markers into an array (for later use) and test the length of that array.

If you will only ever have one marker, don't use fitBounds. Call setCenter, setZoom with the marker position and your desired zoom level.

function addMarker(lat, lng, info) {
  var pt = new google.maps.LatLng(lat, lng);
  map.setCenter(pt);
  map.setZoom(your desired zoom);
}

I like the Infragistics controls. The WebDropDown has what you need. The only drawback is they can be a bit spendy.

This:

STR_TO_DATE(t.datestring, '%d/%m/%Y')

...will convert the string into a datetime datatype. To be sure that it comes out in the format you desire, use DATE_FORMAT:

DATE_FORMAT(STR_TO_DATE(t.datestring, '%d/%m/%Y'), '%Y-%m-%d')

If you can't change the datatype on the original column, I suggest creating a view that uses the STR_TO_DATE call to convert the string to a DateTime data type.

Can you execute python.exe from any map? If you do not, chek if you have proper values for python.exe in PATH enviroment

Are you in same directory than blah.py. Check this by issuing command -> edit blah.py and check if you can open this file

EDIT:

In that case you can not. (python arg means that you call python.exe whit some parameters which python assume that is filename of script you want to run)

You can create bat file whit lines in your path map and run .bat file

Example:
In one of Path maps create blah.py.bat Edit file and put line

python C:\Somedir\blah.py

You can now run blah.py from anywere, becuase you do not need to put .bat extention when running bat files

I know this thread is really old but the solution from @Ivan Bondarenko helped me in my situation.

I had the following in my pom.xml.

<build>
    ...
    <plugins>
         <plugin>
                <groupId>com.consol.citrus</groupId>

What I wanted, was to disable the execution of generate-citrus-war for a specific profile and this was the solution:

                <executions>
                    <!-- disable generating the war for this profile -->
                    <execution>

I had the same problem: my file was not encoded as UTF-8. I have solved it by opening the file with notepad++ and changing the encoding of the file.

Go to "Encoding" and select "Convert to UTF-8". Save changes and that's all!

java.net.URLEncoder.encode(finalPartOfString, "utf-8");

This will URL-encode the string.

finalPartOfString is the part after the last slash - in your case, the name of the song, as it seems.

i know a way ny which you can call you private function to test in mockito

@Test
    public  void  commandEndHandlerTest() throws  Exception
    {
        Method retryClientDetail_privateMethod =yourclass.class.getDeclaredMethod("Your_function_name",null);
        retryClientDetail_privateMethod.setAccessible(true);
        retryClientDetail_privateMethod.invoke(yourclass.class, null);
    }

Here are some options for using AJAX to upload files:

• AjaxFileUpload - Requires a form element on the page, but uploads the file without reloading the page. See the Demo.

• List of JQuery Plug-ins Tagged With "File"

• Uploadify - A Flash-based method of uploading files.

• How can I upload files asynchronously?

• Ten Examples of AJAX File Upload - This was posted this year.

UPDATE: Here is a JQuery plug-in for Multiple File Uploading.

In namespace RestSharp.Extensions there is method ReadAsBytes. Inside this method is used MemoryStream and there is the same code like in some examples on this page but when you are using RestSharp this is easiest way.

using RestSharp.Extensions;
var byteArray = inputStream.ReadAsBytes();

The simple way is to, Edit your migration file (cascadeDelete: true) into (cascadeDelete: false) then after assign the Update-Database command in your Package Manager Console.if it's problem with your last migration then all right. Otherwise check your earlier migration history, copy those things, paste into your last migration file, after that do it the same thing. it perfectly works for me.

ok i had the same problem and i fix it like this by removing [] from [{"key":"value"}]:

1. in your php file make shure that you print like this

echo json_encode(array_shift($your_variable));

2. in your success function do this

 success: function (data) {
    var result = $.parseJSON(data);
      ('.yourclass').append(result['your_key1']);
      ('.yourclass').append(result['your_key2']);
       ..
    }

and also you can loop it if you want

Writing exception-safe code in C++ is not so much about using lots of try { } catch { } blocks. It's about documenting what kind of guarantees your code provides.

I recommend reading Herb Sutter's Guru Of The Week series, in particular installments 59, 60 and 61.

To summarize, there are three levels of exception safety you can provide:

• Basic: When your code throws an exception, your code does not leak resources, and objects remain destructible.
• Strong: When your code throws an exception, it leaves the state of the application unchanged.
• No throw: Your code never throws exceptions.

Personally, I discovered these articles quite late, so much of my C++ code is definitely not exception-safe.

The Python docs say all that needs to be said, as far as I can see.

setattr(object, name, value)

This is the counterpart of getattr(). The arguments are an object, a string and an arbitrary value. The string may name an existing attribute or a new attribute. The function assigns the value to the attribute, provided the object allows it. For example, setattr(x, 'foobar', 123) is equivalent to x.foobar = 123.

If this isn't enough, explain what you don't understand.

Here's another dodge that I came up with for my base repository class where I needed to order by an arbitrary number of columns:

public function findAll(array $where = [], array $with = [], array $orderBy = [], int $limit = 10)
{
    $result = $this->model->with($with);
    $dataSet = $result->where($where)
        // Conditionally use $orderBy if not empty
        ->when(!empty($orderBy), function ($query) use ($orderBy) {
            // Break $orderBy into pairs
            $pairs = array_chunk($orderBy, 2);
            // Iterate over the pairs
            foreach ($pairs as $pair) {
                // Use the 'splat' to turn the pair into two arguments
                $query->orderBy(...$pair);
            }
        })
        ->paginate($limit)
        ->appends(Input::except('page'));

    return $dataSet;
}

Now, you can make your call like this:

$allUsers = $userRepository->findAll([], [], ['name', 'DESC', 'email', 'ASC'], 100);

Just a tip for this, you don't need the BEGIN and END if it only contains a single statement.

ie:

IF(@Trans_type = 'subscr_signup')    
 set @tmpType = 'premium' 
ELSE iF(@Trans_type = 'subscr_cancel')  
     set    @tmpType = 'basic'

If you want to append text or html to span then you can do it as below.

$('p span#add_here').append('text goes here');

append will add text to span tag at the end.

to replace entire text or html inside of span you can use .text() or .html()

For Angular:

getUserPicture(userId) {   
FB.api('/' + userId, {fields: 'picture.width(800).height(800)'}, function(response) {
  console.log('getUserPicture',response);
});
}

You should use & / | operators and be careful about operator precedence (== has lower precedence than bitwise AND and OR):

df1 = sqlContext.createDataFrame(
    [(1, "a", 2.0), (2, "b", 3.0), (3, "c", 3.0)],
    ("x1", "x2", "x3"))

df2 = sqlContext.createDataFrame(
    [(1, "f", -1.0), (2, "b", 0.0)], ("x1", "x2", "x3"))

df = df1.join(df2, (df1.x1 == df2.x1) & (df1.x2 == df2.x2))
df.show()

## +---+---+---+---+---+---+
## | x1| x2| x3| x1| x2| x3|
## +---+---+---+---+---+---+
## |  2|  b|3.0|  2|  b|0.0|
## +---+---+---+---+---+---+

req.params contains route parameters (in the path portion of the URL), and req.query contains the URL query parameters (after the ? in the URL).

You can also use req.param(name) to look up a parameter in both places (as well as req.body), but this method is now deprecated.

Try inserting <xsl:number format="1. "/><xsl:value-of select="."/><xsl:text> in the place of ???.

Note the "1. " - this is the number format. More info: here

A simple solution is:

df['col_3'] = df[['col_1','col_2']].apply(lambda x: f(*x), axis=1)

I got same logcat message, just realize that string.xml value of array cannot be number/digit, but only text/alphabet is allowed.

I've always had a habit of just using std::endl because it is easy for me to see.

After getting an image from the gallery, just pass the URI in the below method only for Android 4.4 (KitKat):

public String getPath(Uri contentUri) {// Will return "image:x*"

    String wholeID = DocumentsContract.getDocumentId(contentUri);

    // Split at colon, use second item in the array
    String id = wholeID.split(":")[1];

    String[] column = { MediaStore.Images.Media.DATA };

    // Where id is equal to
    String sel = MediaStore.Images.Media._ID + "=?";

    Cursor cursor = getContentResolver().query(
            MediaStore.Images.Media.EXTERNAL_CONTENT_URI, column, sel,
            new String[] { id }, null);

    String filePath = "";

    int columnIndex = cursor.getColumnIndex(column[0]);

    if (cursor.moveToFirst()) {
        filePath = cursor.getString(columnIndex);
    }

    cursor.close();
    return filePath;
}

The default mode for vue-router is hash mode - it uses the URL hash to simulate a full URL so that the page won't be reloaded when the URL changes. To get rid of the hash, we can use the router's history mode, which leverages the history.pushState API to achieve URL navigation without a page reload:

import {routes} from './routes'; //import the routes from routes.js    

const router = new VueRouter({
    routes,
    mode: "history",
});

new Vue({
    el: '#app',
    router,
    render: h => h(App)
});

routes.js

import ComponentName from './ComponentName';

export const routes = [
   {
      path:'/your-path'
      component:ComponentName
   }
]

Reference

No one has mentioned the obvious:

var myCallback = function() { console.log("name or age changed"); };
$scope.$watch("name", myCallback);
$scope.$watch("age", myCallback);

This might mean a little less polling. If you watch both name + age (for this) and name (elsewhere) then I assume Angular will effectively look at name twice to see if it's dirty.

It's arguably more readable to use the callback by name instead of inlining it. Especially if you can give it a better name than in my example.

And you can watch the values in different ways if you need to:

$scope.$watch("buyers", myCallback, true);
$scope.$watchCollection("sellers", myCallback);

$watchGroup is nice if you can use it, but as far as I can tell, it doesn't let you watch the group members as a collection or with object equality.

If you need the old and new values of both expressions inside one and the same callback function call, then perhaps some of the other proposed solutions are more convenient.

I haven’t actually done anything with font-face, so take this with a pinch of salt, but I don’t think there’s any way for the browser to definitively tell if a given web font installed on a user’s machine or not.

The user could, for example, have a different font with the same name installed on their machine. The only way to definitively tell would be to compare the font files to see if they’re identical. And the browser couldn’t do that without downloading your web font first.

Does Firefox download the font when you actually use it in a font declaration? (e.g. h1 { font: 'DejaVu Serif';)?

Why use regex for that. String implements IEnumerable<char>, so you can just use LINQ.

test.Count(c => c == '&')

FileNotFound in this case means you got a 404 from your server - could it be that the server does not like "POST" requests?

When you aren't sure which syntax to choose, especially when there doesn't seem to be much to separate the choices, consult a book on heuristics. As far as I know, the only heuristics book for SQL is 'Joe Celko's SQL Programming Style':

A correlation name is more often called an alias, but I will be formal. In SQL-92, they can have an optional AS operator, and it should be used to make it clear that something is being given a new name. [p16]

This way, if your team doesn't like the convention, you can blame Celko -- I know I do ;)

UPDATE 1: IIRC for a long time, Oracle did not support the AS (preceding correlation name) keyword, which may explain why some old timers don't use it habitually.

UPDATE 2: the term 'correlation name', although used by the SQL Standard, is inappropriate. The underlying concept is that of a ‘range variable’.

UPDATE 3: I just re-read what Celko wrote and he is wrong: the table is not being renamed! I now think:

A correlation name is more often called an alias, but I will be formal. In Standard SQL they can have an optional AS keyword but it should not be used because it may give the impression that something is being renamed when it is not. In fact, it should be omitted to enforce the point that it is a range variable.

You don't need to convert the original entry - you can use TEXT function in the concatenation formula, e.g. with date in A1 use a formula like this

="Today is "&TEXT(A1,"dd-mm-yyyy")

You can change the "dd-mm-yyyy" part as required

Those of us using Python 3.x should do this:

python -c "import sys; print(sys.path)"

C++11 has another (imperfect) option:

std::array<int, 100> a;
a.fill(-1);

<video id="myvideo">
  <source src="path/to/movie.mp4" />
</video>

<p onclick="toggleControls();">Toggle</p>

<script>
var video = document.getElementById("myvideo");

function toggleControls() {
  if (video.hasAttribute("controls")) {
     video.removeAttribute("controls")   
  } else {
     video.setAttribute("controls","controls")   
  }
}
</script>

See it working on jsFiddle: http://jsfiddle.net/dgLds/

It simply wants the ASP control on your ASPX page. I usually place mine right under the tag, or inside first Content area in the master's body (if your using a master page)

<body>
    <form id="form1" runat="server">
        <asp:ScriptManager ID="scriptManager" runat="server"></asp:ScriptManager>
        <div>
            [Content]
        </div>
    </form>
</body>

i tried the last answer from Sandeep Kumar, and i found way more simple :

<option value="1" <c:if test="${item.key == 1}"> selected </c:if>>

Expanding on @jake's answer, the transition will go all the way to the max height value, causing an extremely fast animation - if you set the transitions for both :hover and off you can then control the crazy speed a little bit more.

So the li:hover is when the mouse enters the state and then the transition on the non-hovered property will be the mouse leave.

Hopefully this will be of some help.

e.g:

.sidemenu li ul {
   max-height: 0px;
   -webkit-transition: all .3s ease;
   -moz-transition: all .3s ease;
   -o-transition: all .3s ease;
   -ms-transition: all .3s ease;
   transition: all .3s ease;
}
.sidemenu li:hover ul {
    max-height: 500px;
    -webkit-transition: all 1s ease;
   -moz-transition: all 1s ease;
   -o-transition: all 1s ease;
   -ms-transition: all 1s ease;
   transition: all 1s ease;
}
/* Adjust speeds to the possible height of the list */

Here's a fiddle: http://jsfiddle.net/BukwJ/

If you don't need admin privs for the entire app, or only for a few infrequent changes you can do the changes in a new process and launch it using:

Process.StartInfo.UseShellExecute = true;
Process.StartInfo.Verb = "runas";

which will run the process as admin to do whatever you need with the registry, but return to your app with the normal priviledges. This way it doesn't prompt the user with a UAC dialog every time it launches.

I hate to tell you, but I and others may be using white-list defaults to control our filtering of spam.

This means that all e-mail from an unknown source is automatically spam and diverted into a spam folder. (I don't let my e-mail service delete spam, because I want to always review the arrivals for false positives, something that is pretty easy to do by a quick scan of the folder.)

I even have e-mail from myself go to the spam bucket because (1) I usually don't send e-mail to myself and (2) there are spammers that fake my return address in spam sent to me.

So to get out of the spam designation, I have to consider that your mail might be legitimate (from sender and subject information) and open it first in plaintext (my default for all incoming mail, spam or not) to see if it is legitimate. My spam folder will not use any links in e-mails so I am protected against tricky image links and other misbehavior.

If I want future arrivals from the same source to go to my in box and not be diverted for spam review, I will specify that to my e-mail client. For those organizations that use bulk-mail forwarders and unique sender addresses per mail piece, that's too bad. They never get my approval and always show up in my spam folder, and if I'm busy I will never look at them.

Finally, if an e-mail is not legible in plaintext, even when sent as HTML, I am likely to just delete it unless it is something that I know is of interest to me by virtue of the source and previous valuable experiences.

As you can see, it is ultimately under an users control and there is no automated act that will convince such a system that your mail is legitimate from its structure alone. In this case, you need to play nice, don't do anything that is similar to phishing, and make it easy for users willing to trust your mail to add you to their white list.

In case if someone returns with the same question for Android platform, you cannot use the inbuilt remove() method if you are targeting for Android API-18 or less. The remove() method is added on API level 19. Thus, the best possible thing to do is to extend the JSONArray to create a compatible override for the remove() method.

public class MJSONArray extends JSONArray {

    @Override
    public Object remove(int index) {

        JSONArray output = new JSONArray();     
        int len = this.length(); 
        for (int i = 0; i < len; i++)   {
            if (i != index) {
                try {
                    output.put(this.get(i));
                } catch (JSONException e) {
                    throw new RuntimeException(e);
                }
            }
        } 
        return output;
        //return this; If you need the input array in case of a failed attempt to remove an item.
     }
}

EDIT As Daniel pointed out, handling an error silently is bad style. Code improved.

if you include the / at the start of the include, the include will be taken as the path from the root of the site.

if your site is http://www.example.com/game/forum/files/index.php you can add an include to /includes/boot.inc.php which would resolve to http://www.example.com/includes/boot.inc.php .

You have to be careful with .. traversal as some web servers have it disabled; it also causes problems when you want to move your site to a new machine/host and the structure is a little different.

while (node.hasChildNodes()) {
    node.removeChild(node.lastChild);
}

Short (un-precise) definition:

Compiled language: Entire program is translated to machine code at once, then the machine code is run by the CPU.

Interpreted language: Program is read line-by-line and as soon as a line is read the machine instructions for that line are executed by the CPU.

But really, few languages these days are purely compiled or purely interpreted, it often is a mix. For a more detailed description with pictures, see this thread:

What is the difference between compilation and interpretation?

Or my later blog post:

https://orangejuiceliberationfront.com/the-difference-between-compiler-and-interpreter/

• preg_split if you need to split by regular expressions.
• str_split if you need to split by characters.
• explode if you need to split by something simple.

Also for the future, if you ever want to know what PHP wants you to use if something is deprecated you can always check out the function in the manual and it will tell you alternatives.

EDIT: Per Michael Dillon's answer, SaveAsText does save the commands in a macro without having to go through converting to VBA. I don't know what happened when I tested that, but it didn't produce useful text in the resulting file.

So, I learned something new today!

ORIGINAL POST: To expand the question, I wondered if there was a way to retrieve the contents of a macro from code, and it doesn't appear that there is (at least not in A2003, which is what I'm running).

There are two collections through which you can access stored Macros:

  CurrentDB.Containers("Scripts").Documents
  CurrentProject.AllMacros

The properties that Intellisense identifies for the two collections are rather different, because the collections are of different types. The first (i.e., traditional, pre-A2000 way) is via a documents collection, and the methods/properties/members of all documents are the same, i.e., not specific to Macros.

Likewise, the All... collections of CurrentProject return collections where the individual items are of type Access Object. The result is that Intellisense gives you methods/properties/members that may not exist for the particular document/object.

So far as I can tell, there is no way to programatically retrieve the contents of a macro.

This would stand to reason, as macros aren't of much use to anyone who would have the capability of writing code to examine them programatically.

But if you just want to evaluate what the macros do, one alternative would be to convert them to VBA, which can be done programmatically thus:

  Dim varItem As Variant
  Dim strMacroName As String

  For Each varItem In CurrentProject.AllMacros
    strMacroName = varItem.Name
    'Debug.Print strMacroName
    DoCmd.SelectObject acMacro, strMacroName, True
    DoCmd.RunCommand acCmdConvertMacrosToVisualBasic
    Application.SaveAsText acModule, "Converted Macro- " & strMacroName, _
      CurrentProject.Path & "\" & "Converted Macro- " & strMacroName & ".txt"
  Next varItem

Then you could use the resulting text files for whatever you needed to do.

Note that this has to be run interactively in Access because it uses DoCmd.RunCommand, and you have to click OK for each macro -- tedious for databases with lots of macros, but not too onerous for a normal app, which shouldn't have more than a handful of macros.

To find all files modified in the last 24 hours use the one below. The -1 here means changed 1 day or less ago.

find . -mtime -1 -ls

Sometimes the problem is not how to use python, but with the raw data.
I got this error message

Error tokenizing data. C error: Expected 18 fields in line 72, saw 19.

It turned out that in the column description there were sometimes commas. This means that the CSV file needs to be cleaned up or another separator used.

Make sure you are connecting with a USB and not a lightning cable. I had this problem trying to connect using a cord with lightning cables on both ends and it would not list the device. But switching to a USB to lightning cable worked.

A PHP file must have permissions set to 644. Any folder containing PHP files and PHP access (to upload files, for example) must have permissions set to 755. PHP will run a 500 error when dealing with any file or folder that has permissions set to 777!

Sometimes all the solutions with Workbooks.open is not working no matter how many parameters are set. For me, the fastest solution was to change the List separator in Region & language settings. Region window / Additional settings... / List separator.

If csv is not opening in proper way You probly have set ',' as a list separator. Just change it to ';' and everything is solved. Just the easiest way when "everything is against You" :P

As pointed out, you don't need to. Use the Google AJAX Libraries API, and you get CDN hosting of jQuery for free, as depending on your site assets, jQuery can be one of the larger downloads for users.

Function is a set of logic that can be used to manipulate data.

While, Method is function that is used to manipulate the data of the object where it belongs. So technically, if you have a function that is not completely related to your class but was declared in the class, its not a method; It's called a bad design.

In plain C you can use a pointer/size combination in your API.

void doSomething(MyStruct* mystruct, size_t numElements)
{
    for (size_t i = 0; i < numElements; ++i)
    {
        MyStruct current = mystruct[i];
        handleElement(current);
    }
}

Using pointers is the closest to call-by-reference available in C.

Adding a class with a width of 90% to your input element and adding the following input-icon class to your span would achieve what you want I think.

.input { width: 90%; }
.input-icon {
    display: inline-block;
    height: 22px;
    width: 22px;
    line-height: 22px;
    text-align: center;
    color: #000;
    font-size: 12px;
    font-weight: bold;
    margin-left: 4px;
}

EDIT Per dan's suggestion, it would not be wise to use .input as the class name, some more specific would be advised. I was simply using .input as a generic placeholder for your css

Since this is the first result of google this error, I want to remind that simply click the bottom window error message blue link "Fix Gradle wrapper and re-import project Gradle settings" will auto fix for you now.

You know you can always check to see what others are doing. Open source software tend to allow access to their repositories. For example you could point your SVN browser to http://svn.doctrine-project.org and take a look at the versioning system used by a real project.

Version numbers, tags, it's all there.

I find YAML to be easier on the eyes: less parenthesis, "" etc. Although there is the annoyance of tabs in YAML... but one gets the hang of it.

In terms of performance/resources, I wouldn't expect big differences between the two.

Futhermore, we are talking about configuration files and so I wouldn't expect a high frequency of encode/decode activity, no?

Probably the author won't need my answer anymore. Still, for sake of completeness i feel other users might find it useful. The best and most simple solution is to use $(window).load() inside the body of the returned function. (alternatively you can use document.ready. It really depends if you need all the images or not).

Using $timeout in my humble opinion is a very weak option and may fail in some cases.

Here is the complete code i'd use:

.directive('directiveExample', function(){
   return {
       restrict: 'A',
       link: function($scope, $elem, attrs){

           $(window).load(function() {
               //...JS here...
           });
       }
   }
});

@echo off

set "language=de"

IF "%language%" == "de" (
    goto languageDE
) ELSE (
    IF "%language%" == "en" (
        goto languageEN
    ) ELSE (
    echo Not found.
    )
)

:languageEN
:languageDE

echo %language%

This works , but not sure how your language variable is defined.Does it have spaces in its definition.

Add script with query parameters

That was my case. It actually links to question #4485874, but I'm going to explain it here shortly.
When you try to require path/to/script.php?parameter=value, PHP looks for file named script.php?parameter=value, because UNIX allows you to have paths like this.
If you are really need to pass some data to included script, just declare it as $variable=... or $GLOBALS[]=... or other way you like.

git reset --hard origin/master

You probably wanted to ask this before you ran the command. The destructive nature is hinted at by using the same words as in "hard reset".

** Update ** A scalars converter has been added to retrofit that allows for a String response with less ceremony than my original answer below.

Example interface --

public interface GitHubService {
    @GET("/users/{user}")
    Call<String> listRepos(@Path("user") String user);
}

Add the ScalarsConverterFactory to your retrofit builder. Note: If using ScalarsConverterFactory and another factory, add the scalars factory first.

Retrofit retrofit = new Retrofit.Builder()
    .baseUrl(BASE_URL)
    .addConverterFactory(ScalarsConverterFactory.create())
    // add other factories here, if needed.
    .build();

You will also need to include the scalars converter in your gradle file --

implementation 'com.squareup.retrofit2:converter-scalars:2.1.0'

--- Original Answer (still works, just more code) ---

I agree with @CommonsWare that it seems a bit odd that you want to intercept the request to process the JSON yourself. Most of the time the POJO has all the data you need, so no need to mess around in JSONObject land. I suspect your specific problem might be better solved using a custom gson TypeAdapter or a retrofit Converter if you need to manipulate the JSON. However, retrofit provides more the just JSON parsing via Gson. It also manages a lot of the other tedious tasks involved in REST requests. Just because you don't want to use one of the features, doesn't mean you have to throw the whole thing out. There are times you just want to get the raw stream, so here is how to do it -

First, if you are using Retrofit 2, you should start using the Call API. Instead of sending an object to convert as the type parameter, use ResponseBody from okhttp --

public interface GitHubService {
    @GET("/users/{user}")
    Call<ResponseBody> listRepos(@Path("user") String user);
}

then you can create and execute your call --

GitHubService service = retrofit.create(GitHubService.class);
Call<ResponseBody> result = service.listRepos(username);
result.enqueue(new Callback<ResponseBody>() {
    @Override
    public void onResponse(Response<ResponseBody> response) {
        try {
            System.out.println(response.body().string());
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

    @Override
    public void onFailure(Throwable t) {
        e.printStackTrace();
    }
});

Note The code above calls string() on the response object, which reads the entire response into a String. If you are passing the body off to something that can ingest streams, you can call charStream() instead. See the ResponseBody docs.

Worksheets("Sheet1").Range("A1:A5").Copy
Worksheets("Sheet2").Range("A1").PasteSpecial Transpose:=True

This works good for me. I have divided the screen into two halfs: 20% and 80%:

<div style="width: 20%; float:left">
   #left content in here
</div>

<div style="width: 80%; float:right">
   #right content in there
</div>

Check out section 5.14.2. Moving files and folders (or check out "move" in the Index of the help) of the TortoiseSVN help. You do a move via right-dragging. It also mentions that you need to commit from the parent folder to make it "one" revision. This works for doing the change in a working copy.

(Note that the SVN items in the following image will only show up if the destination folder has already been added to the repository.)

You can also do the move via the Repo Browser (section 5.23. The Repository Browser of the help).

We can use params, new feature of the UI-Router:

API Reference / ui.router.state / $stateProvider

params A map which optionally configures parameters declared in the url, or defines additional non-url parameters. For each parameter being configured, add a configuration object keyed to the name of the parameter.

See the part: "...or defines additional non-url parameters..."

So the state def would be:

$stateProvider
  .state('home', {
    url: "/home",
    templateUrl: 'tpl.html',
    params: { hiddenOne: null, }
  })

Few examples form the doc mentioned above:

// define a parameter's default value
params: {
  param1: { value: "defaultValue" }
}
// shorthand default values
params: {
  param1: "defaultValue",
  param2: "param2Default"
}

// param will be array []
params: {
  param1: { array: true }
}

// handling the default value in url:
params: {
  param1: {
    value: "defaultId",
    squash: true
} }
// squash "defaultValue" to "~"
params: {
  param1: {
    value: "defaultValue",
    squash: "~"
  } }

EXTEND - working example: http://plnkr.co/edit/inFhDmP42AQyeUBmyIVl?p=info

Here is an example of a state definition:

 $stateProvider
  .state('home', {
      url: "/home",
      params : { veryLongParamHome: null, },
      ...
  })
  .state('parent', {
      url: "/parent",
      params : { veryLongParamParent: null, },
      ...
  })
  .state('parent.child', { 
      url: "/child",
      params : { veryLongParamChild: null, },
      ...
  })

This could be a call using ui-sref:

<a ui-sref="home({veryLongParamHome:'Home--f8d218ae-d998-4aa4-94ee-f27144a21238'
  })">home</a>

<a ui-sref="parent({ 
    veryLongParamParent:'Parent--2852f22c-dc85-41af-9064-d365bc4fc822'
  })">parent</a>

<a ui-sref="parent.child({
    veryLongParamParent:'Parent--0b2a585f-fcef-4462-b656-544e4575fca5',  
    veryLongParamChild:'Child--f8d218ae-d998-4aa4-94ee-f27144a61238'
  })">parent.child</a>

Check the example here

Perhaps a simple way to remember: add a dot after the numerator (or denominator)

16 ** (1. / 2)   # 4
289 ** (1. / 2)  # 17
27 ** (1. / 3)   # 3

[int(i) for i in str(number)]

or, if do not want to use a list comprehension or you want to use a base different from 10

from __future__ import division # for compatibility of // between Python 2 and 3
def digits(number, base=10):
    assert number >= 0
    if number == 0:
        return [0]
    l = []
    while number > 0:
        l.append(number % base)
        number = number // base
    return l

I think this is what you want:

document.getElementById('tag-id').innerHTML = '<ol><li>html data</li></ol>';

Keep in mind that innerHTML is not accessible for all types of tags when using IE. (table elements for example)

A faster, easier and more flexible way to do this is to use the strgen module (pip install StringGenerator).

Generate a 6-character random string with upper case letters and digits:

>>> from strgen import StringGenerator as SG
>>> SG("[\u\d]{6}").render()
u'YZI2CI'

Get a unique list:

>>> SG("[\l\d]{10}").render_list(5,unique=True)
[u'xqqtmi1pOk', u'zmkWdUr63O', u'PGaGcPHrX2', u'6RZiUbkk2i', u'j9eIeeWgEF']

Guarantee one "special" character in the string:

>>> SG("[\l\d]{10}&[\p]").render()
u'jaYI0bcPG*0'

A random HTML color:

>>> SG("#[\h]{6}").render()
u'#CEdFCa'

etc.

We need to be aware that this:

''.join(random.choice(string.ascii_uppercase + string.digits) for _ in range(N))

might not have a digit (or uppercase character) in it.

strgen is faster in developer-time than any of the above solutions. The solution from Ignacio is the fastest run-time performing and is the right answer using the Python Standard Library. But you will hardly ever use it in that form. You will want to use SystemRandom (or fallback if not available), make sure required character sets are represented, use unicode (or not), make sure successive invocations produce a unique string, use a subset of one of the string module character classes, etc. This all requires lots more code than in the answers provided. The various attempts to generalize a solution all have limitations that strgen solves with greater brevity and expressive power using a simple template language.

It's on PyPI:

pip install StringGenerator

Disclosure: I'm the author of the strgen module.

How about an extension method?

Here I have a show or hide method. Using my CSS class hidden.

public static class HtmlControlExtensions
{
    public static void Hide(this HtmlControl ctrl)
    {
        if (!string.IsNullOrEmpty(ctrl.Attributes["class"]))
        {
            if (!ctrl.Attributes["class"].Contains("hidden"))
                ctrl.Attributes.Add("class", ctrl.Attributes["class"] + " hidden");
        }
        else
        {
            ctrl.Attributes.Add("class", "hidden");
        }
    }

    public static void Show(this HtmlControl ctrl)
    {
        if (!string.IsNullOrEmpty(ctrl.Attributes["class"]))
            if (ctrl.Attributes["class"].Contains("hidden"))
                ctrl.Attributes.Add("class", ctrl.Attributes["class"].Replace("hidden", ""));
    }
}

Then when you want to show or hide your control:

myUserControl.Hide();

//... some other code

myUserControl.Show();

You can do this go to Settings > Storage, clicking on the setting menu icon in the top right hand corner and selecting "USB computer connection". I then changed the storage mode to "Camera (PTP)". Done try re installing the driver from device manager.

One simple use case when reverting change:
1. Use reset if you want to undo staging of a modified file.
2. Use checkout if you want to discard changes to unstaged file/s.

On the very left of the Chrome Developer Tools toolbar there is a button that lets you select an item to inspect regardless of context menu handlers. It looks like a square with arrow pointing to the center.

Mac OS X doesn't have apt-get. There is a package manager called Homebrew that is used instead.

This command would be:

brew install python

Use Homebrew to install packages that you would otherwise use apt-get for.

The page I linked to has an up-to-date way of installing homebrew, but at present, you can install Homebrew as follows:

Type the following in your Mac OS X terminal:

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

After that, usage of Homebrew is brew install <package>.

One of the prerequisites for Homebrew are the XCode command line tools.

1. Install XCode from the App Store.
2. Follow the directions in this Stack Overflow answer to install the XCode Command Line Tools.

Background

A package manager (like apt-get or brew) just gives your system an easy and automated way to install packages or libraries. Different systems use different programs. apt and its derivatives are used on Debian based linux systems. Red Hat-ish Linux systems use rpm (or at least they did many, many, years ago). yum is also a package manager for RedHat based systems.

Alpine based systems use apk.

Warning

As of 25 April 2016, homebrew opts the user in to sending analytics by default. This can be opted out of in two ways:

Setting an environment variable:

1. Open your favorite environment variable editor.
2. Set the following: HOMEBREW_NO_ANALYTICS=1 in whereever you keep your environment variables (typically something like ~/.bash_profile)
3. Close the file, and either restart the terminal or source ~/.bash_profile.

Running the following command:

brew analytics off

the analytics status can then be checked with the command:

brew analytics

I was able to find a solution/workaround of redirecting output to a file and then to the console:

dir > a.txt | type a.txt

where dir is the command which output needs to be redirected, a.txt a file where to store output.

Try below

Something..TrimEnd(",".ToCharArray());

Create a generic ICloneable<T> interface which you implement in your Book class so that the class knows how to create a copy of itself.

public interface ICloneable<T>
{
    T Clone();
}

public class Book : ICloneable<Book>
{
    public Book Clone()
    {
        return new Book { /* set properties */ };
    }
}

You can then use either the linq or ConvertAll methods that Mark mentioned.

List<Book> books_2 = books_1.Select(book => book.Clone()).ToList();

or

List<Book> books_2 = books_1.ConvertAll(book => book.Clone());

Try this:

1. Download and install a 32-bit JDK.
2. Go to eclipse click on your project (Run As ? Run Configurations...) under Java Application branch.
3. Go to the JRE tab and select Alternate JRE. Click on Installed JRE button, add your 32-bit JRE and select.

I am adding this answer since programmers coming to VBA from more modern languages and searching Stack Overflow for multithreading in VBA might be unaware of a couple of native VBA approaches which sometimes help to compensate for VBA's lack of true multithreading.

If the motivation of multithreading is to have a more responsive UI that doesn't hang when long-running code is executing, VBA does have a couple of low-tech solutions that often work in practice:

1) Userforms can be made to display modelessly - which allows the user to interact with Excel while the form is open. This can be specified at runtime by setting the Userform's ShowModal property to false or can be done dynamically as the from loads by putting the line

UserForm1.Show vbModeless

in the user form's initialize event.

2) The DoEvents statement. This causes VBA to cede control to the OS to execute any events in the events queue - including events generated by Excel. A typical use-case is updating a chart while code is executing. Without DoEvents the chart won't be repainted until after the macro is run, but with Doevents you can create animated charts. A variation of this idea is the common trick of creating a progress meter. In a loop which is to execute 10,000,000 times (and controlled by the loop index i ) you can have a section of code like:

If i Mod 10000 = 0 Then
    UpdateProgressBar(i) 'code to update progress bar display
    DoEvents
End If

None of this is multithreading -- but it might be an adequate kludge in some cases.

Just cast one of the two operands to a float first.

v = (float)s / t;

The cast has higher precedence than the division, so happens before the division.

The other operand will be effectively automatically cast to a float by the compiler because the rules say that if either operand is of floating point type then the operation will be a floating point operation, even if the other operand is integral. Java Language Specification, §4.2.4 and §15.17

Run this command in project root directory.

1>. List of iPhone devices for found the connected Real Devices and Simulator. same as like adb devices command for android.

xcrun instruments -s devices

2>. Select device using this command which you want to run your app

Using Device Name

react-native run-ios --device "Kool's iPhone"

Using UDID

react-native run-ios --device --udid 0412e2c2******51699

wait and watch to run your app in specific devices - K00L ;)

To suppress output, use redirection to NUL.

There are two kinds of output that console commands use:

• standard output, or stdout,

• standard error, or stderr.

Of the two, stdout is used more often, both by internal commands, like copy, and by console utilities, or external commands, like find and others, as well as by third-party console programs.

>NUL suppresses the standard output and works fine e.g. for suppressing the 1 file(s) copied. message of the copy command. An alternative syntax is 1>NUL. So,

COPY file1 file2 >NUL

or

COPY file1 file2 1>NUL

or

>NUL COPY file1 file2

or

1>NUL COPY file1 file2

suppresses all of COPY's standard output.

To suppress error messages, which are typically printed to stderr, use 2>NUL instead. So, to suppress a File Not Found message that DEL prints when, well, the specified file is not found, just add 2>NUL either at the beginning or at the end of the command line:

DEL file 2>NUL

or

2>NUL DEL file

Although sometimes it may be a better idea to actually verify whether the file exists before trying to delete it, like you are doing in your own solution. Note, however, that you don't need to delete the files one by one, using a loop. You can use a single command to delete the lot:

IF EXIST "%scriptDirectory%*.noext" DEL "%scriptDirectory%*.noext"

Try also this:

$('#divId').find('input').serialize()

Create a backup and clone the repository into a fresh directory

cp -R foo foo-backup
git clone git@url:foo foo-new

(optional) If you are working on a different branch than master, switch it.

cd foo-new
git checkout -b branch-name origin/branch-name

Sync changes excluding the .git directory

rsync -aP --exclude=.git foo-backup/ foo-new

Old topic but maybe the easiest is to use Apache commons NumberUtils which has a method createBigDecimal (String value)....

I guess (hope) it takes locales into account or else it would be rather useless.

Use a GET request to download the image and save it to a web accessible directory on your server.

As you are using PHP, you can use curl to download files from the other server.

Make sure you have the right selector, and then wait until the page is ready and that the element exists until you run the function.

$(function(){
    $('#searchBar').val('hi')
});

As Derek points out, the ID is wrong as well.

Change to $('#main_search')

Selecting the text to fix, and CtrlK, CtrlF shortcut certainly works. However, I generally find that if a particular method (for instance) has it's indentation messed up, simply removing the closing brace of the method, and re-adding, in fact fixes the indentation anyway, thereby doing without the need to select the code before hand, ergo is quicker. ymmv.

You can use ax.figure.savefig():

import pandas as pd

s = pd.Series([0, 1])
ax = s.plot.hist()
ax.figure.savefig('demo-file.pdf')

This has no practical benefit over ax.get_figure().savefig() as suggested in Philip Cloud's answer, so you can pick the option you find the most aesthetically pleasing. In fact, get_figure() simply returns self.figure:

# Source from snippet linked above
def get_figure(self):
    """Return the `.Figure` instance the artist belongs to."""
    return self.figure

I have created a utils method to check a SD card is available on device or not, and get SD card path on device if it available.

For those who don't want elegant solutions, just a quick and dirty way to stop those messages, here is a solution that worked for me (I use Hibernate 4.3.6 and Eclipse and no answers provided above (or found on the internet) worked; neither log4j config files nor setting the logging level programatically)

public static void main(String[] args) {
    //magical - do not touch
    @SuppressWarnings("unused")
    org.jboss.logging.Logger logger = org.jboss.logging.Logger.getLogger("org.hibernate");
    java.util.logging.Logger.getLogger("org.hibernate").setLevel(java.util.logging.Level.WARNING); //or whatever level you need

    ...
}

I used it in a tutorial program downloaded from this site

...
    xmlns:msxsl="urn:schemas-microsoft-com:xslt"
    xmlns:local="urn:local" extension-element-prefixes="msxsl">

    <msxsl:script language="CSharp" implements-prefix="local">
        public string dateTimeNow()
        {       
          return DateTime.Now.ToString("yyyy-MM-ddTHH:mm:ssZ"); 
        } 
    </msxsl:script>  
...
    <xsl:value-of select="local:dateTimeNow()"/>

Seems to be pure inertia. Where it is in use, everyone is too busy to learn IDL or numpy in sufficient detail to switch, and don't want to rewrite good working programs. Luckily that's not strictly true, but true enough in enough places that Matlab will be around a long time. Like Fortran (in active use where i work!)

Use RGB values combined with opacity to get the transparency that you wish.

For instance,

<div style=" background: rgb(255, 0, 0) ; opacity: 0.2;">&nbsp;</div>
<div style=" background: rgb(255, 0, 0) ; opacity: 0.4;">&nbsp;</div>
<div style=" background: rgb(255, 0, 0) ; opacity: 0.6;">&nbsp;</div>
<div style=" background: rgb(255, 0, 0) ; opacity: 0.8;">&nbsp;</div>
<div style=" background: rgb(255, 0, 0) ; opacity: 1;">&nbsp;</div>

Similarly, with actual values without opacity, will give the below.

<div style=" background: rgb(243, 191, 189) ; ">&nbsp;</div>
<div style=" background: rgb(246, 143, 142) ; ">&nbsp;</div>
<div style=" background: rgb(249, 95 , 94)  ; ">&nbsp;</div>
<div style=" background: rgb(252, 47, 47)   ; ">&nbsp;</div>
<div style=" background: rgb(255, 0, 0)     ; ">&nbsp;</div>

You can have a look at this WORKING EXAMPLE.

Now, if we specifically target your issue, here is the WORKING DEMO SPECIFIC TO YOUR ISSUE.

The HTML

<div class="social">
    <img src="http://www.google.co.in/images/srpr/logo4w.png" border="0" />

.social img:hover {
    opacity:1;
    background-color:black;
    cursor:pointer;
    background: rgb(255, 0, 0) ; opacity: 0.5;

Hope this helps Now.

Example: Read json from file

/* test.json */
{
   "appDesc": {
      "description": "SomeDescription",
      "message": "SomeMessage"
   },
   "appName": {
      "description": "Home",

      file.open(QIODevice::ReadOnly | QIODevice::Text);
      val = file.readAll();
      file.close();
      qWarning() << val;
      QJsonDocument d = QJsonDocument::fromJson(val.toUtf8());
      QJsonObject sett2 = d.object();

"QJsonObject[appName] of description: " QJsonValue(string, "Home") 
"Home" 
"QJsonObject[appName] of value: " QJsonValue(array, QJsonArray(["awesome","best","good"]) ) 
"best" 

Example: Read json from string

Assign json to string as below and use the readJson() function shown before:

val =   
'  {
       "appDesc": {
          "description": "SomeDescription",
          "message": "SomeMessage"
       },
       "appName": {
          "description": "Home",
          "message": "Welcome",
          "imp":["awesome","best","good"]
       }
    }';

OUTPUT

QJsonValue(object, QJsonObject({"description": "Home","imp": ["awesome","best","good"],"message": "YouTube"}) ) 
"QJsonObject of description: " QJsonObject({"description": "Home","imp": ["awesome","best","good"],"message": "YouTube"}) 
"QJsonObject[appName] of description: " QJsonValue(string, "Home") 
"Home" 
"QJsonObject[appName] of value: " QJsonValue(array, QJsonArray(["awesome","best","good"]) ) 
"best" 

You can also circumvent scope inheritance and store things in the "global" scope.

If you have a main controller in your application which wraps all other controllers, you can install a "hook" to the global scope:

function RootCtrl($scope) {
    $scope.root = $scope;
}

Then in any child controller, you can access the "global" scope with $scope.root. Anything you set here will be globally visible.

Example:

function RootCtrl($scope) {_x000D_
  $scope.root = $scope;_x000D_
}_x000D_
_x000D_
function ChildCtrl($scope) {_x000D_
  $scope.setValue = function() {_x000D_
    $scope.root.someGlobalVar = 'someVal';_x000D_
  }_x000D_
}_x000D_
_x000D_
function OtherChildCtrl($scope) {_x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>_x000D_
_x000D_
<div ng-app ng-controller="RootCtrl">_x000D_
  _x000D_
  <p ng-controller="ChildCtrl">_x000D_
    <button ng-click="setValue()">Set someGlobalVar</button>_x000D_
  </p>_x000D_
  _x000D_
  <p ng-controller="OtherChildCtrl">_x000D_
    someGlobalVar value: {{someGlobalVar}}_x000D_
  </p>_x000D_
_x000D_
</div>

This will get you pretty close, and I use it in production and have never had a collision. However, if you look at the constructor for a guid in reflector, you will see all of the checks it makes.

 public static bool GuidTryParse(string s, out Guid result)
    {
        if (!String.IsNullOrEmpty(s) && guidRegEx.IsMatch(s))
        {
            result = new Guid(s);
            return true;
        }

        result = default(Guid);
        return false;
    }

    static Regex guidRegEx = new Regex("^[A-Fa-f0-9]{32}$|" +
                          "^({|\\()?[A-Fa-f0-9]{8}-([A-Fa-f0-9]{4}-){3}[A-Fa-f0-9]{12}(}|\\))?$|" +

Following the instructions laid out in Facebook's extending page tokens documentation I was able to get a page access token that does not expire.

I suggest using the Graph API Explorer for all of these steps except where otherwise stated.

0. Create Facebook App

If you already have an app, skip to step 1.

1. Go to My Apps.
2. Click "+ Add a New App".
3. Setup a website app.

You don't need to change its permissions or anything. You just need an app that wont go away before you're done with your access token.

1. Get User Short-Lived Access Token

1. Go to the Graph API Explorer.
2. Select the application you want to get the access token for (in the "Application" drop-down menu, not the "My Apps" menu).
3. Click "Get Token" > "Get User Access Token".
4. In the pop-up, under the "Extended Permissions" tab, check "manage_pages".
5. Click "Get Access Token".
6. Grant access from a Facebook account that has access to manage the target page. Note that if this user loses access the final, never-expiring access token will likely stop working.

The token that appears in the "Access Token" field is your short-lived access token.

2. Generate Long-Lived Access Token

Following these instructions from the Facebook docs, make a GET request to

https://graph.facebook.com/v2.10/oauth/access_token?grant_type=fb_exchange_token&client_id={app_id}&client_secret={app_secret}&fb_exchange_token={short_lived_token}

entering in your app's ID and secret and the short-lived token generated in the previous step.

You cannot use the Graph API Explorer. For some reason it gets stuck on this request. I think it's because the response isn't JSON, but a query string. Since it's a GET request, you can just go to the URL in your browser.

The response should look like this:

{"access_token":"ABC123","token_type":"bearer","expires_in":5183791}

"ABC123" will be your long-lived access token. You can put it into the Access Token Debugger to verify. Under "Expires" it should have something like "2 months".

3. Get User ID

Using the long-lived access token, make a GET request to

https://graph.facebook.com/v2.10/me?access_token={long_lived_access_token}

The id field is your account ID. You'll need it for the next step.

4. Get Permanent Page Access Token

Make a GET request to

https://graph.facebook.com/v2.10/{account_id}/accounts?access_token={long_lived_access_token}

The JSON response should have a data field under which is an array of items the user has access to. Find the item for the page you want the permanent access token from. The access_token field should have your permanent access token. Copy it and test it in the Access Token Debugger. Under "Expires" it should say "Never".

Here is a nearly complete example javascript function that will allow multiple markers defined in a JSONObject.

It will only display the markers that are with in the bounds of the map.

This is important so you are not doing extra work.

You can also set a limit to the markers so you are not showing an extreme amount of markers (if there is a possibility of a thing in your usage);

it will also not display markers if the center of the map has not changed more than 500 meters.
This is important because if a user clicks on the marker and accidentally drags the map while doing so you don't want the map to reload the markers.

I attached this function to the idle event listener for the map so markers will show only when the map is idle and will redisplay the markers after a different event.

All of the other answers focus on individually checking every file, but if the files are all in one directory (folder), it might be much more efficient to just read the directory and check for the existence of every file name you want.

This might even be more efficient even if the files are spread across several directories, depends on the exact ratio of directories to files. Once you start getting closer to each target file being in its own directory, or there being lots of other files in the same directories which you don't want to check for, then I'd expect it to finally tip over into being less efficient than checking each file individually.

A good heuristic: working on a bunch of data you already have is much faster than asking the operating system for any amount of data. System call overhead is huge relative to individual machine instructions. So it is almost always going to be faster to ask the OS "give me the entire list of files in this directory" and then to dig through that list, and slower to ask the OS "give me information on this file", "okay now give me information on this other file", "now give me information on ...", and so on.

Every good C library implements its "iterate over all files in a directory" APIs in an efficient way, just like buffered I/O - internally it reads up a big list of directory entries from the OS at once, even though the APIs look like asking the OS for each entry individually.

So if I had this requirement, I would

1. do everything possible to encourage the design and usage so that all the files were in one folder, and no other files were in that folder,
2. put the list of file names that I need to be present into a data structure in memory that has O(1) or at least O(log(n)) lookup and delete times (like a hash map or a binary tree),
3. list the files in that directory, and "check off" (delete) each one as I went from the "list" (hash map or binary tree) in memory.

Except depending on the exact use case, maybe instead of deleting entries from a hash map or tree, I would keep track of a "do I have this file?" boolean for each entry, and figure out a data structure that would make it O(1) to ask "do I have every file?". Maybe a binary tree but the struct for each non-leaf node also has a boolean that is a logical-and of the booleans of its leaf nodes. That scales well - after setting a boolean in a leaf node, you just walk up the tree and set each node's "have this?" boolean with the && of its child node's boolean (and you don't need to recurse down those other child nodes, since if you're doing this process consistently every time you go to set one of the leaves to true, they will be set to true if and only if all of their children are.)

Sadly, there is no standard way to do it until C++17.

C++17 got std::filesystem::directory_iterator.

Of course there is a corresponding boost::filesystem::directory_iterator which I presume will work in older versions of C++.

The closest thing to a standard C way is opendir and readdir from dirent.h. That is a standard C interface, it's just standardized in POSIX and not in the C standard itself. It comes is available out-of-the-box on Mac OS, Linux, all the BSDs, other UNIX/UNIX-like systems, and any other POSIX/SUS system. For Windows, there is a dirent.h implementation that you just have to download and drop into your include path.

However, since you're looking for the fastest way, you might want to look beyond the portable/standard stuff.

On Linux, you might be able to optimize your performance by manually specifying the buffer size with the raw system call getdents64.

On Windows, after a bit of digging, it looks like for maximum performance you want to use FindFirstFileEx with FindExInfoBasic and FIND_FIRST_EX_LARGE_FETCH when you can, which a lot of the open source libraries like the above dirent.h for Windows don't seem to do. But for code that needs to work with stuff older than the last couple Windows versions, you might as well just use the straightforward FindFirstFile without the extra flags.

Plan 9 won't be covered by any of the above, and there you'll want dirread or dirreadall (the latter if you can safely assume you have enough memory for the entire directory contents). If you want more control over the buffer size for performance use plain read or read and decode the directory entry data - they're in a documented machine-independent format and I think there's helper functions provided.

I don't know about any other operating systems.

I might edit this answer with some tests later. Others are welcome to edit in test results as well.

You are missing the ()

Python comes with a script that takes care of setting up the windows path file for you.

After installation, open command prompt

cmd

Go to the directory you installed Python in

cd C:\Python27

Run python and the win_add2path.py script in Tools\Scripts

python.exe Tools\Scripts\win_add2path.py

Now you can use python as a command anywhere.

You can also use lib-auto

 xmlns:app="http://schemas.android.com/apk/lib-auto"

setting up a special stack frame for the try/catch adds additional overhead, but the JVM may be able to detect the fact that you're returning and optimize this away.

depending on the number of iterations, performance difference will likely be negligible.

However i agree with the others that having it outside the loop make the loop body look cleaner.

If there's a chance that you'll ever want to continue on with the processing rather than exit if there an invalid number, then you would want the code to be inside the loop.

Another option would be to use the chromestorage API. This allows storage of user data with optional syncing across sessions.

One downside is that it is asynchronous.

Try this out. After going through a lot of posts and forums, I found this.

mWebView.setDownloadListener(new DownloadListener() {       

    @Override
    public void onDownloadStart(String url, String userAgent,
                                    String contentDisposition, String mimetype,
                                    long contentLength) {
            DownloadManager.Request request = new DownloadManager.Request(
                    Uri.parse(url));

            request.allowScanningByMediaScanner();
            request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED); //Notify client once download is completed!
            request.setDestinationInExternalPublicDir(Environment.DIRECTORY_DOWNLOADS, "Name of your downloadble file goes here, example: Mathematics II ");
            DownloadManager dm = (DownloadManager) getSystemService(DOWNLOAD_SERVICE);
            dm.enqueue(request);
            Toast.makeText(getApplicationContext(), "Downloading File", //To notify the Client that the file is being downloaded
                    Toast.LENGTH_LONG).show();

        }
    });

Do not forget to give this permission! This is very important! Add this in your Manifest file(The AndroidManifest.xml file)

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />        <!-- for your file, say a pdf to work -->

Hope this helps. Cheers :)

Two files: 1) An app.config or web.config file. The settings her can be customized after build with a text editer. 2) The settings.designer.cs file. This file has autogenerated code to load the setting from the config file, but a default value is also present in case the config file does not have the particular setting.

I have encountered such a problem when grouping object, i always resolved them by a simple way: perform a custom filter using a java.util.Set to remove duplicate object with whatever attribute of your choice as bellow

Set<String> uniqueNames = new HashSet<>();
Map<String, String> phoneBook = people
                  .stream()
                  .filter(person -> person != null && !uniqueNames.add(person.getName()))
                  .collect(toMap(Person::getName, Person::getAddress));

Hope this helps anyone having the same problem !

This question is a few years old, and there are some good suggestions for workarounds, but I didn't really notice any answers that address the core of the original question head-on. So:

• Providing a "universal" method for viewing source in a feature phone browser (or even arbitrary third-party smartphone browser) is impossible because "view source" — via any method — is a feature implemented in the browser. So how it's accessed, or even if it can be accessed, is up to the developers of the browser. I'm sure there are plenty of browsers that intentionally prevent the user from viewing page source, and if so then you're out of luck, except maybe for workarounds like the ones offered here.

• Workarounds such as "view source" apps external to the browser, while useful in some cases, are at best an imperfect partial solution to the original request. It's never certain that any such app will display the source of the page in the same form as it's loaded by the phone's browser.

  Modern web content changes itself in all manner of ways through browser detection, session management, etc. so that the source loaded by any external app can never be relied on to represent the source as loaded by a different app. If you're going to use an external app to load a page because you want to see the source, you might as well just use Chrome (or, on an iOS device, Safari) instead.

I am not very sure whether it will make any difference in performance of my API.

Bear in mind that the primary benefit of asynchronous code on the server side is scalability. It won't magically make your requests run faster. I cover several "should I use async" considerations in my article on async ASP.NET.

I think your use case (calling other APIs) is well-suited for asynchronous code, just bear in mind that "asynchronous" does not mean "faster". The best approach is to first make your UI responsive and asynchronous; this will make your app feel faster even if it's slightly slower.

As far as the code goes, this is not asynchronous:

public Task<BackOfficeResponse<List<Country>>> ReturnAllCountries()
{
  var response = _service.Process<List<Country>>(BackOfficeEndpoint.CountryEndpoint, "returnCountries");
  return Task.FromResult(response);
}

You'd need a truly asynchronous implementation to get the scalability benefits of async:

public async Task<BackOfficeResponse<List<Country>>> ReturnAllCountriesAsync()
{
  return await _service.ProcessAsync<List<Country>>(BackOfficeEndpoint.CountryEndpoint, "returnCountries");
}

Or (if your logic in this method really is just a pass-through):

public Task<BackOfficeResponse<List<Country>>> ReturnAllCountriesAsync()
{
  return _service.ProcessAsync<List<Country>>(BackOfficeEndpoint.CountryEndpoint, "returnCountries");
}

Note that it's easier to work from the "inside out" rather than the "outside in" like this. In other words, don't start with an asynchronous controller action and then force downstream methods to be asynchronous. Instead, identify the naturally asynchronous operations (calling external APIs, database queries, etc), and make those asynchronous at the lowest level first (Service.ProcessAsync). Then let the async trickle up, making your controller actions asynchronous as the last step.

And under no circumstances should you use Task.Run in this scenario.

In case you couldn't find "Import code" button on github, you can:

1. directly open Github Importer and enter the url. It will look like:
2. give it a name (or it will import the name automatically)
3. select Public or Private repo
4. Click Begin Import

UPDATE: Recently, Github announced the ability to "Import repositories with large files"

The External Dependencies folder is populated by IntelliSense: the contents of the folder do not affect the build at all (you can in fact disable the folder in the UI).

You need to actually include the header (using a #include directive) to use it. Depending on what that header is, you may also need to add its containing folder to the "Additional Include Directories" property and you may need to add additional libraries and library folders to the linker options; you can set all of these in the project properties (right click the project, select Properties). You should compare the properties with those of the project that does build to determine what you need to add.

If you download the latest version of Adobe Acrobat Reader, it will tell you if your pdf is PDF/A compliant. Just open the PDF file and a big blue marking should appear.

OpenOffice supports PDF/A. For some reason "PDF/A-1" is called

"SelectPdfVersion"

The different values can be

0 = PDFXNONE
1 = PDFX1A2001
2 = PDFX32002
3 = PDFA1A
4 = PDFA1B

You set

FilterData

HashMap('SelectPdfVersion',1) //1 for PDFX1A2001

I had a long white cable. Just wouldnt stay connected. Switched to another, shorter, black cable and it works 100% of the time.

new(): Specifying the new() constraint means type T must use a parameterless constructor, so an object can be instantiated from it - see Default constructors.

class: Means T must be a reference type so it can't be an int, float, double, DateTime or other struct (value type).

public void MakeCars()
{
    //This won't compile as researchEngine doesn't have a public constructor and so can't be instantiated.
    CarFactory<ResearchEngine> researchLine = new CarFactory<ResearchEngine>();
    var researchEngine = researchLine.MakeEngine();

    //Can instantiate new object of class with default public constructor
    CarFactory<ProductionEngine> productionLine = new CarFactory<ProductionEngine>();
    var productionEngine = productionLine.MakeEngine();
}

public class ProductionEngine { }
public class ResearchEngine
{
    private ResearchEngine() { }
}

public class CarFactory<TEngine> where TEngine : class, new()
{
    public TEngine MakeEngine()
    {
        return new TEngine();
    }
}

Interface is a contract you should comply to or given to, depending if you are implementer or a user.

I had the same issue using SQLite. My problem was that DB_DATABASE was pointing to the wrong file location.

Create the sqlite file with the touch command and output the file path using php artisan tinker.

$ touch database/database.sqlite
$ php artisan tinker
Psy Shell v0.8.0 (PHP 5.6.27 — cli) by Justin Hileman
>>> database_path(‘database.sqlite’)
=> "/Users/connorleech/Projects/laravel-5-rest-api/database/database.sqlite"

Then output that exact path to the DB_DATABASE variable.

DB_CONNECTION=sqlite
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=/Users/connorleech/Projects/laravel-5-rest-api/database/database.sqlite
DB_USERNAME=homestead
DB_PASSWORD=secret

Without the correct path you will get the access denied error

I'm learning Algorithm right now, so i wonder how bisect module writes. Here is the code from bisect module about inserting an item into sorted list, which uses dichotomy:

def insort_right(a, x, lo=0, hi=None):
    """Insert item x in list a, and keep it sorted assuming a is sorted.
    If x is already in a, insert it to the right of the rightmost x.
    Optional args lo (default 0) and hi (default len(a)) bound the
    slice of a to be searched.
    """

    if lo < 0:
        raise ValueError('lo must be non-negative')
    if hi is None:
        hi = len(a)
    while lo < hi:
        mid = (lo+hi)//2
        if x < a[mid]:
            hi = mid
        else:
            lo = mid+1
    a.insert(lo, x)

This works for me in Outlook:

<img src="image.jpg" width="120" style="display:block;width:100%" />

I hope it works for you.

#wrapper
{
    min-width:960px;
    margin-left:auto;
    margin-right:auto;
    position-relative;
}
#left
{
    width:200px;
    position: absolute;
    background-color:antiquewhite;
    margin-left:10px;
    z-index: 2;
}
#content
{
    padding-left:210px;
    width:100%;
    background-color:AppWorkspace;
    position: relative;
    z-index: 1;
}

If you need the whitespace on the right of #left, then add a border-right: 10px solid #FFF; to #left and add 10px to the padding-left in #content

Solutions provided by RC and Luigi R. Viggiano together is possibly the best idea.

Although Mockito cannot, by design, mock final classes, the delegation approach is possible. This has its advantages:

1. You are not forced to change your class to non-final if that is what your API intends in the first place (final classes have their benefits).
2. You are testing the possibility of a decoration around your API.

In your test case, you deliberately forward the calls to the system under test. Hence, by design, your decoration does not do anything.

Hence you test can also demonstrate that the user can only decorate the API instead of extending it.

On a more subjective note: I prefer keeping the frameworks to a minimum, which is why JUnit and Mockito are usually sufficient for me. In fact, restricting this way sometimes forces me to refactor for good as well.

In short, place black behind the image, and lower the opactiy. You can do this by wrapping the image within a div, and then lowering the opacity of the image.

For example:

<!DOCTYPE html>

<style>
    .img-wrap {
        background: black;
        display: inline-block;
        line-height: 0;
    }
        .img-wrap > img {
            opacity: 0.8;
        }
</style>

<div class="img-wrap">
    <img src="http://mikecane.files.wordpress.com/2007/03/kitten.jpg" />
</div>

Here is a JSFiddle.

First declare a object of DecimalFormat class. Note the argument inside the DecimalFormat is #.00 which means exactly 2 decimal places of rounding off.

private static DecimalFormat df2 = new DecimalFormat("#.00");

Now, apply the format to your double value:

double input = 32.123456;
System.out.println("double : " + df2.format(input)); // Output: 32.12

Note in case of double input = 32.1;

Then the output would be 32.10 and so on.

Django 1.10+

Use an attribute, not a method:

if request.user.is_authenticated: # <-  no parentheses any more!
    # do something if the user is authenticated

The use of the method of the same name is deprecated in Django 2.0, and is no longer mentioned in the Django documentation.

return HttpResponse(json.dumps({
    "is_authenticated": request.user.is_authenticated()
}), content_type='application/json') 

that after updated to the property request.user.is_authenticated was throwing the exception TypeError: Object of type 'CallableBool' is not JSON serializable. The solution was to use JsonResponse, which could handle the CallableBool object properly when serializing:

return JsonResponse({
    "is_authenticated": request.user.is_authenticated
})

If someone searching how to toggle header so in componentDidMount write something like:

  this.props.navigation.setParams({

This is more an add-on to the best answer above (GZip Compression can be enabled directly through IIS) which is correct if your running IIS on Windows desktop however...

If your running IIS on Windows Server, this content compression feature is found in a different place to desktop Windows (not in programs and features in Control Panel). First open "Server Manager" then click Manage -> "Add Roles & Features" then keep clicking NEXT (make sure you select the correct server when you see the list of servers if your managing multiple servers from this instance) until you get to SERVER ROLES, scroll down to and open "Web Server (IIS)..." then "Web Server" then "Performance" then tick "Dynamic Content Compression" then click INSTALL. I tested this on Server 2016 Standard so there may be slight differences if your on an earlier version of Server.

Then follow the instructions from Testing - Check if GZIP Compression is Enabled

The problem with your code seems to be the elseif-statement which should be else if (Notice the space).

I rewrote and simplyfied the code to this:

$(document).ready(function () {

    if (screen.width < 1024) {
        $(".yourClass").hide();
    }
    else {

        $(".yourClass").show();
    }

});

There might be something wrong with your formula if you are looking from another sheet maybe you have to change Sheet1 to Sheet2 ---> =VLOOKUP(M3,Sheet2!$A$2:$Q$47,13,FALSE) --- Where Sheet2 is your table array

this.options[this.selectedIndex].innerHTML

should provide you with the "displayed" text of the selected item. this.value, like you said, merely provides the value of the value attribute.

First I'd say you probably want to turn off persistent connections as they almost always do more harm than good.

Secondly I'd say you want to double check your MySQL users, just to make sure it's not possible for anyone to be connecting from a remote server. This is also a major security thing to check.

Thirdly I'd say you want to turn on the MySQL Slow Query Log to keep an eye on any queries that are taking a long time, and use that to make sure you don't have any queries locking up key tables for too long.

Some other things you can check would be to run the following query while the CPU load is high:

SHOW PROCESSLIST;

This will show you any queries that are currently running or in the queue to run, what the query is and what it's doing (this command will truncate the query if it's too long, you can use SHOW FULL PROCESSLIST to see the full query text).

You'll also want to keep an eye on things like your buffer sizes, table cache, query cache and innodb_buffer_pool_size (if you're using innodb tables) as all of these memory allocations can have an affect on query performance which can cause MySQL to eat up CPU.

You'll also probably want to give the following a read over as they contain some good information.

• How MySQL Uses Memory
• MySQL System Variables

It's also a very good idea to use a profiler. Something you can turn on when you want that will show you what queries your application is running, if there's duplicate queries, how long they're taking, etc, etc. An example of something like this is one I've been working on called PHP Profiler but there are many out there. If you're using a piece of software like Drupal, Joomla or Wordpress you'll want to ask around within the community as there's probably modules available for them that allow you to get this information without needing to manually integrate anything.

In Python 3 it's quite easy: read the file and rewrite it with utf-8 encoding:

s = open(bom_file, mode='r', encoding='utf-8-sig').read()
open(bom_file, mode='w', encoding='utf-8').write(s)

here is the split function that u asked

CREATE FUNCTION [dbo].[split](
          @delimited NVARCHAR(MAX),
          @delimiter NVARCHAR(100)
        ) RETURNS @t TABLE (id INT IDENTITY(1,1), val NVARCHAR(MAX))
        AS
        BEGIN
          DECLARE @xml XML
          SET @xml = N'<t>' + REPLACE(@delimited,@delimiter,'</t><t>') + '</t>'

          INSERT INTO @t(val)
          SELECT  r.value('.','varchar(MAX)') as item
          FROM  @xml.nodes('/t') as records(r)
          RETURN
        END

execute the function like this

select * from dbo.split('1,2,3,4,5,6,7,8,9,10,11,12,13,14,15',',')

Night's answer is correct

 html, body {margin:0;padding:0;height:100%;}

Also check that your div or element is NOT inside another one (with height less than 100%) Hope this helps someone else.

Check this code. It gives you the clear solution of JSON parse error. It commonly happen by the newlines and the space between json key start and json key end

data_val = data_val.replace(/[\n\s]{1,}\"/g, "\"")  
               .replace(/\"[\n\s]{1,}/g, "\"")  
               .replace(/[\n]/g, "\\n") 

If you have multiple files or directories and you want to zip them into independent *.gz file you can do this. Optional -type f -atime

find -name "httpd-log*.txt" -type f -mtime +1 -exec tar -vzcf {}.gz {} \;

This will compress

httpd-log01.txt
httpd-log02.txt

to

httpd-log01.txt.gz
httpd-log02.txt.gz

If it's conciseness you're after, you might like:

prop.table(table(tips$smoker))

and then scale by 100 and round if you like. Or more like your exact output:

tbl <- table(tips$smoker)
cbind(tbl,prop.table(tbl))

If you wanted to do this for multiple columns, there are lots of different directions you could go depending on what your tastes tell you is clean looking output, but here's one option:

tblFun <- function(x){
    tbl <- table(x)
    res <- cbind(tbl,round(prop.table(tbl)*100,2))
    colnames(res) <- c('Count','Percentage')
    res
}

do.call(rbind,lapply(tips[3:6],tblFun))
       Count Percentage
Female    87      35.66
Male     157      64.34
No       151      61.89
Yes       93      38.11
Fri       19       7.79
Sat       87      35.66
Sun       76      31.15
Thur      62      25.41
Dinner   176      72.13
Lunch     68      27.87

If you don't like stack the different tables on top of each other, you can ditch the do.call and leave them in a list.

That's works for me accurately

let template = null;
    $('.modal').on('show.bs.modal', function(event) {
      template = $(this).html();
    });

    $('.modal').on('hidden.bs.modal', function(e) {
      $(this).html(template);
    });

Try using:

body {
  background-attachment: fixed;
  background-image: url(./Images/bg4.jpg);
}

Images being folder holding the picture that you want to post.
