You can use this command,

jmeter -n -t /path to the script.jmx -l /path to save results with file name file.jtl

But if you really want to run a load test in a remote machine, you should be able to make it run eventhough you close the window. So we can use nohup to ignore the HUP (hangup) signal. So you can use this command as below.

nohup sh jmeter.sh -n -t /path to the script.jmx -l /path to save results with file name file.jtl &

class PagesController extends BaseController {
    protected $layout = 'layouts.master';

    public function index()
    {
        $this->layout->title = "Home page";
        $this->layout->content = View::make('pages/index');
    }
}

At the Blade Template file, REMEMBER to use @ in front the variable.

...
<title>{{ $title or '' }}</title>
...
@yield('content')
...

In the IntelliJ IDE you just need to type:

""

Then position your cursor inside the quotation marks and paste your string. The IDE will expand it into multiple concatenated lines.

My two cents on Stream. I think it's better to use

IntStream.generate(i -> MyClass.contruct())
         .limit(INT_SIZE)
         .collect(Collectors.toList());

with the flexibility to put any initial values.

Using this code might help. It solved my problem!

mb_convert_encoding($post["post"],'UTF-8','UTF-8');

or like that

mb_convert_encoding($string,'UTF-8','UTF-8');

I believe for this typical case, i.e. to run something with a fixed interval, Timer is more appropriate. Here is a simple example:

myTimer = new Timer();
myTimer.schedule(new TimerTask() {          
@Override
public void run() {
    // If you want to modify a view in your Activity
    MyActivity.this.runOnUiThread(new Runnable()
        public void run(){
            tv.append("Hello World");
        });
    }
}, 1000, 1000); // initial delay 1 second, interval 1 second

Using Timer has few advantages:

• Initial delay and the interval can be easily specified in the schedule function arguments
• The timer can be stopped by simply calling myTimer.cancel()
• If you want to have only one thread running, remember to call myTimer.cancel() before scheduling a new one (if myTimer is not null)

Final keyword has a numerous way to use:

• A final class cannot be subclassed.
• A final method cannot be overridden by subclasses
• A final variable can only be initialized once

Other usage:

• When an anonymous inner class is defined within the body of a method, all variables declared final in the scope of that method are accessible from within the inner class

A static class variable will exist from the start of the JVM, and should be initialized in the class. The error message won't appear if you do this.

That's the compiler that comes with Apple's XCode tools package. They've hacked on it a little, but basically it's just g++.

You can download XCode for free (well, mostly, you do have to sign up to become an ADC member, but that's free too) here: http://developer.apple.com/technology/xcode.html

Edit 2013-01-25: This answer was correct in 2010. It needs an update.

While XCode tools still has a command-line C++ compiler, In recent versions of OS X (I think 10.7 and later) have switched to clang/llvm (mostly because Apple wants all the benefits of Open Source without having to contribute back and clang is BSD licensed). Secondly, I think all you have to do to install XCode is to download it from the App store. I'm pretty sure it's free there.

So, in order to get g++ you'll have to use something like homebrew (seemingly the current way to install Open Source software on the Mac (though homebrew has a lot of caveats surrounding installing gcc using it)), fink (basically Debian's apt system for OS X/Darwin), or MacPorts (Basically, OpenBSDs ports system for OS X/Darwin) to get it.

Fink definitely has the right packages. On 2016-12-26, it had gcc 5 and gcc 6 packages.

I'm less familiar with how MacPorts works, though some initial cursory investigation indicates they have the relevant packages as well.

Hashing:

It is a one-way algorithm and once hashed can not rollback and this is its sweet point against encryption.

Encryption

If we perform encryption, there will a key to do this. If this key will be leaked all of your passwords could be decrypted easily.

On the other hand, even if your database will be hacked or your server admin took data from DB and you used hashed passwords, the hacker will not able to break these hashed passwords. This would actually practically impossible if we use hashing with proper salt and additional security with PBKDF2.

If you want to take a look at how should you write your hash functions, you can visit here.

There are many algorithms to perform hashing.

1. MD5 - Uses the Message Digest Algorithm 5 (MD5) hash function. The output hash is 128 bits in length. The MD5 algorithm was designed by Ron Rivest in the early 1990s and is not a preferred option today.

2. SHA1 - Uses Security Hash Algorithm (SHA1) hash published in 1995. The output hash is 160 bits in length. Although most widely used, this is not a preferred option today.

3. HMACSHA256, HMACSHA384, HMACSHA512 - Use the functions SHA-256, SHA-384, and SHA-512 of the SHA-2 family. SHA-2 was published in 2001. The output hash lengths are 256, 384, and 512 bits, respectively,as the hash functions’ names indicate.

To get all rows, don't specify the key. Try this:

$meta_values = get_post_meta( get_the_ID() );

var_dump( $meta_values );

Hope it helps!

the difference is not between <span> and <div> specifically, but between inline and block elements. <span> defaults to being display:inline; whereas <div> defaults to being display:block;. But these can be overridden in CSS.

The difference in the way text-align:center works between the two is down to the width.

A block element defaults to being the width of its container. It can have its width set using CSS, but either way it is a fixed width.

An inline element takes its width from the size of its content text.

text-align:center tells the text to position itself centrally in the element. But in an inline element, this is clearly not going to have any effect because the element is the same width as the text; aligning it one way or the other is meaningless.

In a block element, because the element's width is independent of the content, the content can be positioned within the element using the text-align style.

Finally, a solution for you:

There is an additional value for the display property which provides a half-way house between block and inline. Conveniently enough, it's called inline-block. If you specify a <span> to be display:inline-block; in the CSS, it will continue to work as an inline element but will take on some of the properties of a block as well, such as the ability to specify a width. Once you specify a width for it, you will be able to center the text within that width using text-align:center;

Hope that helps.

Any spaces in the names of the columns in Excel caused the error for me. Once I removed any spaces then it imported with no problems.

Also, one things that may help to understand:

math.js

this.add = function (a, b) {
    return a + b;
};

client.js

var math = require('./math');
console.log(math.add(2,2); // 4;

Great, in this case:

console.log(this === module.exports); // true
console.log(this === exports); // true
console.log(module.exports === exports); // true

Thus, by default, "this" is actually equals to module.exports.

However, if you change your implementation to:

math.js

var add = function (a, b) {
    return a + b;
};

module.exports = {
    add: add
};

In this case, it will work fine, however, "this" is not equal to module.exports anymore, because a new object was created.

console.log(this === module.exports); // false
console.log(this === exports); // true
console.log(module.exports === exports); // false

And now, what will be returned by the require is what was defined inside the module.exports, not this or exports, anymore.

Another way to do it would be:

math.js

module.exports.add = function (a, b) {
    return a + b;
};

Or:

math.js

exports.add = function (a, b) {
    return a + b;
};

        frame.setLayout(new FlowLayout());
        frame.setSize(200,300);

    }
}

The correct shortcut is CTRL-R-W like you don't have to release CTRL button while pressing W. This worked for me in VS 2015

There is another alternative. Instead of manipulating the pseudo-classes directly, create real classes that model the same things, like a "hover" class or a "visited" class. Style the classes with the usual "." syntax and then you can use JavaScript to add or remove classes from an element when the appropriate event fires.

The string that you pass to the constructor JSONObject has to be escaped with quote():

public static java.lang.String quote(java.lang.String string)

Your code would now be:

JSONObject jsonObj = new JSONObject.quote(jsonString.toString());
System.out.println(jsonString);
System.out.println("---------------------------");
System.out.println(jsonObj);

You could do this using SUMIF. This allows you to SUM a value in a cell IF a value in another cell meets the specified criteria. Here's an example:

 -   A         B
 1   100       YES
 2   100       YES
 3   100       NO

Using the formula: =SUMIF(B1:B3, "YES", A1:A3), you will get the result of 200.

Here's a screenshot of a working example I just did in Excel:

As Nikolai has said you can use the gdb 'set' command to change the value of a variable.

You can also use the 'set' command to change memory locations. eg. Expanding on Nikolai's example:

(gdb) l
6       {
7           int i;
8           struct file *f, *ftmp;
9
(gdb) set variable i = 10
(gdb) p i
$1 = 10

(gdb) p &i
$2 = (int *) 0xbfbb0000
(gdb) set *((int *) 0xbfbb0000) = 20
(gdb) p i
$3 = 20

This should work for any valid pointer, and can be cast to any appropriate data type.

I adapted some code to create a TouchImageView that supports multitouch (>2.1). It is inspired by the book Hello, Android! (3rd edition)

In addition to the already posted answer, I thought I should share a handy trick I use to load all the DLL functions into the program through function pointers, without writing a separate GetProcAddress call for each and every function. I also like to call the functions directly as attempted in the OP.

Start by defining a generic function pointer type:

typedef int (__stdcall* func_ptr_t)();

What types that are used aren't really important. Now create an array of that type, which corresponds to the amount of functions you have in the DLL:

func_ptr_t func_ptr [DLL_FUNCTIONS_N];

In this array we can store the actual function pointers that point into the DLL memory space.

Next problem is that GetProcAddress expects the function names as strings. So create a similar array consisting of the function names in the DLL:

const char* DLL_FUNCTION_NAMES [DLL_FUNCTIONS_N] = 
{
  "dll_add",
  "dll_subtract",
  "dll_do_stuff",
  ...
};

Now we can easily call GetProcAddress() in a loop and store each function inside that array:

for(int i=0; i<DLL_FUNCTIONS_N; i++)
{
  func_ptr[i] = GetProcAddress(hinst_mydll, DLL_FUNCTION_NAMES[i]);

  if(func_ptr[i] == NULL)
  {
    // error handling, most likely you have to terminate the program here
  }
}

If the loop was successful, the only problem we have now is calling the functions. The function pointer typedef from earlier isn't helpful, because each function will have its own signature. This can be solved by creating a struct with all the function types:

typedef struct
{
  int  (__stdcall* dll_add_ptr)(int, int);
  int  (__stdcall* dll_subtract_ptr)(int, int);
  void (__stdcall* dll_do_stuff_ptr)(something);
  ...
} functions_struct;

And finally, to connect these to the array from before, create a union:

typedef union
{
  functions_struct  by_type;
  func_ptr_t        func_ptr [DLL_FUNCTIONS_N];
} functions_union;

Now you can load all the functions from the DLL with the convenient loop, but call them through the by_type union member.

But of course, it is a bit burdensome to type out something like

functions.by_type.dll_add_ptr(1, 1); whenever you want to call a function.

As it turns out, this is the reason why I added the "ptr" postfix to the names: I wanted to keep them different from the actual function names. We can now smooth out the icky struct syntax and get the desired names, by using some macros:

#define dll_add (functions.by_type.dll_add_ptr)
#define dll_subtract (functions.by_type.dll_subtract_ptr)
#define dll_do_stuff (functions.by_type.dll_do_stuff_ptr)

And voilà, you can now use the function names, with the correct type and parameters, as if they were statically linked to your project:

int result = dll_add(1, 1);

Disclaimer: Strictly speaking, conversions between different function pointers are not defined by the C standard and not safe. So formally, what I'm doing here is undefined behavior. However, in the Windows world, function pointers are always of the same size no matter their type and the conversions between them are predictable on any version of Windows I've used.

Also, there might in theory be padding inserted in the union/struct, which would cause everything to fail. However, pointers happen to be of the same size as the alignment requirement in Windows. A static_assert to ensure that the struct/union has no padding might be in order still.

It sounds like you're looking for applicationHost.config, which is located in C:\Windows\System32\inetsrv\config.

Yes, it's an XML file, and yes, editing the file by hand will affect the IIS config after a restart. You can think of IIS Manager as a GUI front-end for editing applicationHost.config and web.config.

I had similar problem before. But this was resolved when I started using hostname instead of IP address in my connection string.

Bottom Line

Your code has retrieved data (entities) via entity-framework with lazy-loading enabled and after the DbContext has been disposed, your code is referencing properties (related/relationship/navigation entities) that was not explicitly requested.

More Specifically

The InvalidOperationException with this message always means the same thing: you are requesting data (entities) from entity-framework after the DbContext has been disposed.

A simple case:

(these classes will be used for all examples in this answer, and assume all navigation properties have been configured correctly and have associated tables in the database)

public class Person
{
  public int Id { get; set; }
  public string name { get; set; }
  public int? PetId { get; set; }
  public Pet Pet { get; set; }
}

public class Pet 
{
  public string name { get; set; }
}

using (var db = new dbContext())
{
  var person = db.Persons.FirstOrDefaultAsync(p => p.id == 1);
}

Console.WriteLine(person.Pet.Name);

The last line will throw the InvalidOperationException because the dbContext has not disabled lazy-loading and the code is accessing the Pet navigation property after the Context has been disposed by the using statement.

Debugging

How do you find the source of this exception? Apart from looking at the exception itself, which will be thrown exactly at the location where it occurs, the general rules of debugging in Visual Studio apply: place strategic breakpoints and inspect your variables, either by hovering the mouse over their names, opening a (Quick)Watch window or using the various debugging panels like Locals and Autos.

If you want to find out where the reference is or isn't set, right-click its name and select "Find All References". You can then place a breakpoint at every location that requests data, and run your program with the debugger attached. Every time the debugger breaks on such a breakpoint, you need to determine whether your navigation property should have been populated or if the data requested is necessary.

Ways to Avoid

Disable Lazy-Loading

public class MyDbContext : DbContext
{
  public MyDbContext()
  {
    this.Configuration.LazyLoadingEnabled = false;
  }
}

Pros: Instead of throwing the InvalidOperationException the property will be null. Accessing properties of null or attempting to change the properties of this property will throw a NullReferenceException.

How to explicitly request the object when needed:

using (var db = new dbContext())
{
  var person = db.Persons
    .Include(p => p.Pet)
    .FirstOrDefaultAsync(p => p.id == 1);
}
Console.WriteLine(person.Pet.Name);  // No Exception Thrown

In the previous example, Entity Framework will materialize the Pet in addition to the Person. This can be advantageous because it’s a single call the the database. (However, there can also be huge performance problems depending on the number of returned results and the number of navigation properties requested, in this instance, there would be no performance penalty because both instances are only a single record and a single join).

or

using (var db = new dbContext())
{
  var person = db.Persons.FirstOrDefaultAsync(p => p.id == 1);

  var pet = db.Pets.FirstOrDefaultAsync(p => p.id == person.PetId);
}
Console.WriteLine(person.Pet.Name);  // No Exception Thrown

In the previous example, Entity Framework will materialize the Pet independently of the Person by making an additional call to the database. By default, Entity Framework tracks objects it has retrieved from the database and if it finds navigation properties that match it will auto-magically populate these entities. In this instance because the PetId on the Person object matches the Pet.Id, Entity Framework will assign the Person.Pet to the Pet value retrieved, before the value is assigned to the pet variable.

I always recommend this approach as it forces programmers to understand when and how code is request data via Entity Framework. When code throws a null reference exception on a property of an entity, you can almost always be sure you have not explicitly requested that data.

For IE 7 & 8 (and other browsers without CSS3 support not including IE6) you can use the following to get the 2nd and 3rd children:

2nd Child:

td:first-child + td

3rd Child:

td:first-child + td + td

Then simply add another + td for each additional child you wish to select.

If you want to support IE6 that can be done too! You simply need to use a little javascript (jQuery in this example):

$(function() {
    $('td:first-child').addClass("firstChild");
    $(".table-class tr").each(function() {
        $(this).find('td:eq(1)').addClass("secondChild");
        $(this).find('td:eq(2)').addClass("thirdChild");
    });
});

Then in your css you simply use those class selectors to make whatever changes you like:

table td.firstChild { /*stuff here*/ }
table td.secondChild { /*stuff to apply to second td in each row*/ }

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

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

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

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

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

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

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

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

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

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

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

exec sp_executesql @query;

ALTER TABLE allitems
CHANGE itemid itemid INT(10) AUTO_INCREMENT;

The 'new' way to install tensorflow GPU if you have Nvidia, is with Anaconda. Works on Windows too. With 1 line.

conda create --name tf_gpu tensorflow-gpu 

This is a shortcut for 3 commands, which you can execute separately if you want or if you already have a conda environment and do not need to create one.

1. Create an anaconda environment conda create --name tf_gpu

2. Activate the environment activate tf_gpu

3. Install tensorflow-GPU conda install tensorflow-gpu

You can use the conda environment.

If by numbers between 1 and 10 you mean any float that is >= 1 and < 10, then it's easy:

select random() * 9 + 1

This can be easily tested with:

# select min(i), max(i) from (
    select random() * 9 + 1 as i from generate_series(1,1000000)
) q;
       min       |       max
-----------------+------------------
 1.0000083274208 | 9.99999571684748
(1 row)

If you want integers, that are >= 1 and < 10, then it's simple:

select trunc(random() * 9 + 1)

And again, simple test:

# select min(i), max(i) from (
    select trunc(random() * 9 + 1) as i from generate_series(1,1000000)
) q;
 min | max
-----+-----
   1 |   9
(1 row)

Seems like a Permissions Issue. I was facing the same error. But when I ran it from the root account, it worked. So either give the read permission to the file using chmod (in linux) or run your script after logging in as a root user.

First you have to include the file you call:

#!/bin/bash
. includes/included_file.sh

then you call your function like this:

#!/bin/bash
my_called_function

The problem is that they're all the same exact list in memory. When you use the [x]*n syntax, what you get is a list of n many x objects, but they're all references to the same object. They're not distinct instances, rather, just n references to the same instance.

To make a list of 3 different lists, do this:

x = [[] for i in range(3)]

This gives you 3 separate instances of [], which is what you want

[[]]*n is similar to

l = []
x = []
for i in range(n):
    x.append(l)

While [[] for i in range(3)] is similar to:

x = []
for i in range(n):
    x.append([])   # appending a new list!

In [20]: x = [[]] * 4

In [21]: [id(i) for i in x]
Out[21]: [164363948, 164363948, 164363948, 164363948] # same id()'s for each list,i.e same object


In [22]: x=[[] for i in range(4)]

In [23]: [id(i) for i in x]
Out[23]: [164382060, 164364140, 164363628, 164381292] #different id(), i.e unique objects this time

If you're doing fragment caching, you can manually break the cache by updating your cache key, like so:

Version #1

<% cache ['cool_name_for_cache_key', 'v1'] do %>

Version #2

<% cache ['cool_name_for_cache_key', 'v2'] do %>

Or you can have the cache automatically reset based on the state of a non-static object, such as an ActiveRecord object, like so:

<% cache @user_object do %>

With this ^ method, any time the user object is updated, the cache will automatically be reset.

List(Of String) will handle that, mostly - though you need to either use AddRange to add a collection of items, or Add to add one at a time:

lstOfString.Add(String1)
lstOfString.Add(String2)
lstOfString.Add(String3)
lstOfString.Add(String4)

If you're adding known values, as you show, a good option is to use something like:

Dim inputs() As String = { "some value", _
                              "some value2", _
                              "some value3", _
                              "some value4" }

Dim lstOfString as List(Of String) = new List(Of String)(inputs)

' ...
Dim s3 = lstOfStrings(3)

This will still allow you to add items later as desired, but also get your initial values in quickly.

Edit:

In your code, you need to fix the declaration. Change:

Dim lstWriteBits() As List(Of String) 

To:

Dim lstWriteBits As List(Of String) 

Currently, you're declaring an Array of List(Of String) objects.

you can use

empty($result) 

to check if the main array is empty or not.

But since you have a SimpleXMLElement object, you need to query the object if it is empty or not. See http://www.php.net/manual/en/simplexmlelement.count.php

ex:

if (empty($result) || !isset($result['Tags'])) {
    return false;
}
if ( !($result['Tags'] instanceof SimpleXMLElement)) {
    return false;
}
return ($result['Tags']->count());

Configure Fiddler as a 'reverse proxy' on Windows

(for Mac, see the link in Partizano's comment below)

I know there's already an answer suggesting this, however I want to provide the explanation and instructions for this that Telerik should have provided, and also cover some of the 'gotchas', so here goes:

What does it mean to configure Fiddler as a 'reverse proxy'?

• By default, Fiddler only monitors outgoing requests from the machine on which you're running Fiddler
• To monitor incoming requests, you need to configure Fiddler to work as a 'reverse proxy'
• What this means is that you need to set Fiddler up as a 'proxy' that will intercept incoming http requests that are sent to a specific port (8888) on the machine where you want to listen to the incoming requests. Fiddler will then forward those requests to the web server on the same machine by sending them to the usual port for http requests (usually port 80 or 443 for https). It's actually very quick and easy to do!
• The standard way to set this up with Fiddler is to get Fiddler to intercept all request sent to Port '8888' (since this won't normally be used by anything else, although you could just as easily use another port)
• You then need to use the registry editor to get Fiddler to forward any http requests that Fiddler receives on port 8888, so that they're forwarded to the standard http port (port 80, port 443 for an https request, or another custom port that your web server is set to listen on)

NOTE: For this to work, any request you want to intercept must be sent to port 8888

You do this by appending :8888 to your hostname, for example like this for an MVC route:

http://myhostname:8888/controller/action

Walkthrough

Ensure Fiddler can accept remote http requests on port 8888:

Run Fiddler as administrator Go to Tools > Fiddler Options > Connections, and ensure that 'Allow remote computers to connect' is checked, and 'Fiddler listens on port' is set to 8888:

Configure Fiddler to forward requests received on port 8888 to port 80

• Close Fiddler
• Start REGEDIT
• Create a new DWORD named ReverseProxyForPort inside HKEY_CURRENT_USER\SOFTWARE\Microsoft\Fiddler2.
  • Now set the DWORD value to the local port you'd like to re-route inbound traffic to (generally port 80 for a standard HTTP server)
• To do this, right-click the DWORD you created and select 'Modify'. Ensure 'Base' is set to 'Decimal' and enter '80' (or another port) as the 'Value data':

Ensure that port 8888 is opened on the firewall

• You must ensure that port 8888 is open to external requests (it won't be by default if your server is firewall-protected)

That's it! Fiddler should now be set up as a reverse proxy, to intercept all requests from port 8888 (so that you can view them in Fiddler), and it will then forward them to your web server to actually be handled.

Test a request

• Restart Fiddler
• To test that Fiddler is intercepting external requests, open a browser on the same machine where you've set up Fiddler as a reverse proxy. Navigate your browser to http://127.0.0.1:8888
• This tests making a basic request to to port 8888
• You should see the request intercepted by Fiddler
• Now you can test a request from another machine, for example by making a request from a browser on another machine like this (where 'remoteHostname' is a hostname on the machine where you've set up Fiddler as a reverse proxy) :

http://remoteHostname:8888/controller/action

• Alternatively, you can compose a request by using another instance of Fiddler on a remote machine, using a URL similar to the one above. This will allow you to make either a GET or a POST request.

IMPORTANT: Once you've finished viewing your request(s), go back to Tools > Fiddler Options > Connections and remove the 'Allow remote computers to connect' option, otherwise 3rd parties will be able to bounce traffic through your server

Clickatell is a popular SMS gateway. It works in 200+ countries.

Their API offers a choice of connection options via: HTTP/S, SMPP, SMTP, FTP, XML, SOAP. Any of these options can be used from php.

The HTTP/S method is as simple as this:

http://api.clickatell.com/http/sendmsg?to=NUMBER&msg=Message+Body+Here

The SMTP method consists of sending a plain-text e-mail to: [email protected], with the following body:

user: xxxxx
password: xxxxx
api_id: xxxxx
to: 448311234567
text: Meet me at home

You can also test the gateway (incoming and outgoing) for free from your browser

Use:

• :ls - to list buffers
• :bd#n - to close buffer where #n is the buffer number (use ls to get it)

Examples:

• to delete buffer 2:

  :bd2
  

By default git push updates all the remote branches. But you can configure git to update only the current branch to it's upstream.

git config push.default upstream

It means git will update only the current (checked out) branch when you do git push.

Other valid options are:

• nothing : Do not push anything (error out) unless a refspec is explicitly given. This is primarily meant for people who want to avoid mistakes by always being explicit.
• matching : Push all branches having the same name on both ends. (default option prior to Ver 1.7.11)
• upstream: Push the current branch to its upstream branch. This mode only makes sense if you are pushing to the same repository you would normally pull from (i.e. central workflow). No need to have the same name for local and remote branch.
• tracking : Deprecated, use upstream instead.
• current : Push the current branch to the remote branch of the same name on the receiving end. Works in both central and non-central workflows.
• simple : [available since Ver 1.7.11] in centralized workflow, work like upstream with an added safety to refuse to push if the upstream branch’s name is different from the local one. When pushing to a remote that is different from the remote you normally pull from, work as current. This is the safest option and is suited for beginners. This mode has become the default in Git 2.0.

Use the shell function test:

foo:
    test $(something)

Usage:

$ make foo
test 
Makefile:2: recipe for target 'foo' failed
make: *** [foo] Error 1
$ make foo something=x
test x

This code is using the new React context API:

  import React, { PureComponent, createContext } from 'react';

  const { Provider, Consumer } = createContext({ width: 0, height: 0 });

  class WindowProvider extends PureComponent {
    state = this.getDimensions();

    componentDidMount() {
      window.addEventListener('resize', this.updateDimensions);
    }

    componentWillUnmount() {
      window.removeEventListener('resize', this.updateDimensions);
    }

    getDimensions() {
      const w = window;
      const d = document;
      const documentElement = d.documentElement;
      const body = d.getElementsByTagName('body')[0];
      const width = w.innerWidth || documentElement.clientWidth || body.clientWidth;
      const height = w.innerHeight || documentElement.clientHeight || body.clientHeight;

      return { width, height };
    }

    updateDimensions = () => {
      this.setState(this.getDimensions());
    };

    render() {
      return <Provider value={this.state}>{this.props.children}</Provider>;
    }
  }

Then you can use it wherever you want in your code like this:

<WindowConsumer>
  {({ width, height }) =>  //do what you want}
</WindowConsumer>

document.getElementsByTagName("html")[0].classList.add('theme-dark');
document.getElementsByTagName("html")[0].classList.remove('theme-dark')
document.getElementsByTagName("html")[0].classList.toggle('theme-dark')

You could add a span before the link with a specific class like so:

<div class="btn btn_red"><span class="icon"></span><a href="#">Crimson</a><span></span></div>

And then give that a specific width and a background image just like you are doing with the button itself.

.btn span.icon {
    background: url(imgs/icon.png) no-repeat;
    float: left;
    width: 10px;
    height: 40px;
}

I am no CSS guru but off the top of my head I think that should work.

The trick is to read the declaration backwards (right-to-left):

const int a = 1; // read as "a is an integer which is constant"
int const a = 1; // read as "a is a constant integer"

Both are the same thing. Therefore:

a = 2; // Can't do because a is constant

The reading backwards trick especially comes in handy when you're dealing with more complex declarations such as:

const char *s;      // read as "s is a pointer to a char that is constant"
char c;
char *const t = &c; // read as "t is a constant pointer to a char"

*s = 'A'; // Can't do because the char is constant
s++;      // Can do because the pointer isn't constant
*t = 'A'; // Can do because the char isn't constant
t++;      // Can't do because the pointer is constant

Use SHOW OPEN TABLES: http://dev.mysql.com/doc/refman/5.1/en/show-open-tables.html

You can do something like this

SHOW OPEN TABLES WHERE `Table` LIKE '%[TABLE_NAME]%' AND `Database` LIKE '[DBNAME]' AND In_use > 0;

to check any locked tables in a database.

I know this is an old question, I'd like to post my approach anyway. This way you don't have to handle the 0 trick that T. J. Crowder expained.

var keepGoing = true;

function myLoop() {
    // ... Do something ...

    if(keepGoing) {
        setTimeout(myLoop, 1000);
    }
}

function startLoop() {
    keepGoing = true;
    myLoop();
}

function stopLoop() {
    keepGoing = false;
}

Maybe this is obvious, maybe not, but you can make the string '\' by calling x=chr(92)

x=chr(92)
print type(x), len(x) # <type 'str'> 1
y='\\'
print type(y), len(y) # <type 'str'> 1
x==y   # True
x is y # False

Your code won't work because you haven't assigned anything to n before you first use it. Try this:

def oracle():
    n = None
    while n != 'Correct':
        # etc...

A more readable approach is to move the test until later and use a break:

def oracle():
    guess = 50

    while True:
        print 'Current number = {0}'.format(guess)
        n = raw_input("lower, higher or stop?: ")
        if n == 'stop':
            break
        # etc...

Also input in Python 2.x reads a line of input and then evaluates it. You want to use raw_input.

Note: In Python 3.x, raw_input has been renamed to input and the old input method no longer exists.

This is what I have tried out:

1. You need to make sure you give your buttons different names
2. Write an if statement that will do the required action if either button is clicked.

<form>
    <input type="text" name="field1" /> <!-- Put your cursor in this field and press Enter -->

    <input type="submit" name="prev" value="Previous Page" /> <!-- This is the button that will submit -->
    <input type="submit" name="next" value="Next Page" /> <!-- But this is the button that I WANT to submit -->
</form>

In PHP,

if(isset($_POST['prev']))
{
    header("Location: previous.html");
    die();
}

if(isset($_POST['next']))
{
    header("Location: next.html");
    die();
}

this could do it:

perl -ne 'if(m/name="(.*?)"/){ print $1 . "\n"; }'

A module could be in the following states:

• imported
• available on disk (or local network)
• available in online gallery

If you just want to have the darn thing available in a PowerShell session for use, here is a function that will do that or exit out if it cannot get it done:

function Load-Module ($m) {

    # If module is imported say that and do nothing
    if (Get-Module | Where-Object {$_.Name -eq $m}) {
        write-host "Module $m is already imported."
    }
    else {

        # If module is not imported, but available on disk then import
        if (Get-Module -ListAvailable | Where-Object {$_.Name -eq $m}) {
            Import-Module $m -Verbose
        }
        else {

            # If module is not imported, not available on disk, but is in online gallery then install and import
            if (Find-Module -Name $m | Where-Object {$_.Name -eq $m}) {
                Install-Module -Name $m -Force -Verbose -Scope CurrentUser
                Import-Module $m -Verbose
            }
            else {

                # If module is not imported, not available and not in online gallery then abort
                write-host "Module $m not imported, not available and not in online gallery, exiting."
                EXIT 1
            }
        }
    }
}

Load-Module "ModuleName" # Use "PoshRSJob" to test it out

Update the master branch, which you need to do regardless.

Then, one of:

1. Rebase the old branch against the master branch. Solve the merge conflicts during rebase, and the result will be an up-to-date branch that merges cleanly against master.

2. Merge your branch into master, and resolve the merge conflicts.

3. Merge master into your branch, and resolve the merge conflicts. Then, merging from your branch into master should be clean.

None of these is better than the other, they just have different trade-off patterns.

I would use the rebase approach, which gives cleaner overall results to later readers, in my opinion, but that is nothing aside from personal taste.

To rebase and keep the branch you would:

git checkout <branch> && git rebase <target>

In your case, check out the old branch, then

git rebase master 

to get it rebuilt against master.

The following is a group of versatile C functions for timer management based on the gettimeofday() system call. All the timer properties are contained in a single ticktimer struct - the interval you want, the total running time since the timer initialization, a pointer to the desired callback you want to call, the number of times the callback was called. A callback function would look like this:

void your_timer_cb (struct ticktimer *t) {
  /* do your stuff here */
}

To initialize and start a timer, call ticktimer_init(your_timer, interval, TICKTIMER_RUN, your_timer_cb, 0).

In the main loop of your program call ticktimer_tick(your_timer) and it will decide whether the appropriate amount of time has passed to invoke the callback.

To stop a timer, just call ticktimer_ctl(your_timer, TICKTIMER_STOP).

New Feature of Java Standard Edition (JSE 7)

1. Decorate Components with the JLayer Class:

   The JLayer class is a flexible and powerful decorator for Swing components. The JLayer class in Java SE 7 is similar in spirit to the JxLayer project project at java.net. The JLayer class was initially based on the JXLayer project, but its API evolved separately.

2. Strings in switch Statement:

   In the JDK 7 , we can use a String object in the expression of a switch statement. The Java compiler generates generally more efficient bytecode from switch statements that use String objects than from chained if-then-else statements.

3. Type Inference for Generic Instance:

   We can replace the type arguments required to invoke the constructor of a generic class with an empty set of type parameters (<>) as long as the compiler can infer the type arguments from the context. This pair of angle brackets is informally called the diamond. Java SE 7 supports limited type inference for generic instance creation; you can only use type inference if the parameterized type of the constructor is obvious from the context. For example, the following example does not compile:

   List<String> l = new ArrayList<>();
   l.add("A");
   l.addAll(new ArrayList<>());
   

   In comparison, the following example compiles:

   List<? extends String> list2 = new ArrayList<>();
   l.addAll(list2);
   

4. Catching Multiple Exception Types and Rethrowing Exceptions with Improved Type Checking:

   In Java SE 7 and later, a single catch block can handle more than one type of exception. This feature can reduce code duplication. Consider the following code, which contains duplicate code in each of the catch blocks:

   catch (IOException e) {
       logger.log(e);
       throw e;
   }
   catch (SQLException e) {
       logger.log(e);
       throw e;
   }
   

   In releases prior to Java SE 7, it is difficult to create a common method to eliminate the duplicated code because the variable e has different types. The following example, which is valid in Java SE 7 and later, eliminates the duplicated code:

   catch (IOException|SQLException e) {
       logger.log(e);
       throw e;
   }
   

   The catch clause specifies the types of exceptions that the block can handle, and each exception type is separated with a vertical bar (|).

5. The java.nio.file package

   The java.nio.file package and its related package, java.nio.file.attribute, provide comprehensive support for file I/O and for accessing the file system. A zip file system provider is also available in JDK 7.

join is not a jQuery function .Its a javascript function.

The join() method joins the elements of an array into a string, and returns the string.The elements will be separated by a specified separator. The default separator is comma (,).

http://www.w3schools.com/jsref/jsref_join.asp

Here is an alternative that works also

public final class Storage : AnyObject {

    var object:Any?

    public init(_ object:Any) {
        self.object = object
    }
}

extension Date {

    private static let associationMap = NSMapTable<NSString, AnyObject>()
    private struct Keys {
        static var Locale:NSString = "locale"
    }

    public var locale:Locale? {
        get {

            if let storage = Date.associationMap.object(forKey: Keys.Locale) {
                return (storage as! Storage).object as? Locale
            }
            return nil
        }
        set {
            if newValue != nil {
                Date.associationMap.setObject(Storage(newValue), forKey: Keys.Locale)
            }
        }
    }
}



var date = Date()
date.locale = Locale(identifier: "pt_BR")
print( date.locale )

From my perspective it is more semantic to use <hr> elements as line breaks between flex items.

.container {_x000D_
  display: flex;_x000D_
  flex-flow: wrap;_x000D_
}_x000D_
_x000D_
.container hr {_x000D_
  width: 100%;_x000D_
}

<div class="container">_x000D_
  <div>1</div>_x000D_
  <div>2</div>_x000D_
  <hr>_x000D_
  <div>3</div>_x000D_
  <div>2</div>_x000D_
  ..._x000D_
</div>

Tested in Chrome 66, Firefox 60 and Safari 11.

The correct path shouldn't end with "/", I had it wrong that caused the trouble

Right way:

http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd

I usually come across this when the port which the server (I use JBoss) is already in use

Usual suspects

1. Apache Http Server => turn down the service if working in windows.
2. IIS => stop the ISS using
3. Skype =>yea I got skype attaching itself to port 80

To change the port to which JBoss 4.2.x binds itself go to:

"C:\jboss4.2.2\server\default\deploy\jboss-web.deployer\server.xml"

here default is the instance of the server change the port here :

<Connector port="8080" address="${jboss.bind.address}" >

In the above example the port is bound to 8080

This doesn't require jQuery. The JavaScript Math.random function returns a random number between 0 and 1, so if you want a number between 1 and 6, you can do:

var number = 1 + Math.floor(Math.random() * 6);

Update: (as per comment) If you want to display a random number that changes every so often, you can use setInterval to create a timer:

setInterval(function() {
  var number = 1 + Math.floor(Math.random() * 6);
  $('#my_div').text(number);
},
1000); // every 1 second

.disabledLink.disabled {pointer-events:none;}

That should do it hope I helped!

A special case is when trying to assess if a boolean value is nil:

false.present? == false
false.blank? == true
false.nil? == false

In this case the recommendation would be to use .nil?

Here is the syntax using jQuery $.get

$.get(url, data, successCallback, datatype)

So in your case, that would equate to,

var url = 'ajax.asp';
var data = { ajaxid: 4, UserID: UserID, EmailAddress: EmailAddress };
var datatype = 'jsonp';

function success(response) {
// do something here 
}

$.get('ajax.aspx', data, success, datatype)

Note $.get does not give you the opportunity to set an error handler. But there are several ways to do it either using $.ajaxSetup(), $.ajaxError() or chaining a .fail on your $.get like below

$.get(url, data, success, datatype)
 .fail(function(){
})

The reason for setting the datatype as 'jsonp' is due to browser same origin policy issues, but if you are making the request on the same domain where your javascript is hosted, you should be fine with datatype set to json.

If you don't want to use the jquery $.get then see the docs for $.ajax which allows room for more flexibility

When you run

install.packages("whatever")

you got message that your binaries are downloaded into temporary location (e.g. The downloaded binary packages are in C:\Users\User_name\AppData\Local\Temp\RtmpC6Y8Yv\downloaded_packages ). Go there. Take binaries (zip file). Copy paste into location which you get from running the code:

.libPaths()

If libPaths shows 2 locations, then paste into second one. Load library:

library(whatever)

Fixed.

Why not just convert all <button> to <span> with type="button" and then style with your normal css button classes? Just confirmed that this works in IE11.

Python allows you to use a string as an iterator:

for character in 'string':
    print(character)

I'm guessing it's your job to figure out how to turn that into a while loop.

You could also just use system("pause");

I'm not really sure of your question, but if all you really want is list currently opened screen session, try:

screen -ls

In the Hibernate Manual you can see this example

Session session = sessionFactory.openSession();
Transaction tx = session.beginTransaction();

for (int i = 0; i < 100000; i++) {
    Customer customer = new Customer(...);
    session.save(customer);
    if (i % 20 == 0) { // 20, same as the JDBC batch size
        // flush a batch of inserts and release memory:
        session.flush();
        session.clear();
    }
}

tx.commit();
session.close();

Without the call to the flush method, your first-level cache would throw an OutOfMemoryException

Also you can look at this post about flushing

Another simple solution is to use map() as follows:

tensor_shape = map(int, my_tensor.shape)

This converts all the Dimension objects to int

If you want a quick and easy solution (and you have gulp installed).

In my gulpfile.js I run a simple copy paste task that puts any files I might need into ./public/modules/ directory.

gulp.task('modules', function() {
    sources = [
      './node_modules/prismjs/prism.js',
      './node_modules/prismjs/themes/prism-dark.css',
    ]
    gulp.src( sources ).pipe(gulp.dest('./public/modules/'));
});

gulp.task('copy-modules', ['modules']);

The downside to this is that it isn't automated. However, if all you need is a few scripts and styles copied over (and kept in a list), this should do the job.

There are 2 solutions for this, but it return all columns separately:

import functools

dfs = [df1, df2, df3]

df_final = functools.reduce(lambda left,right: pd.merge(left,right,on='date'), dfs)
print (df_final)
          date     a_x   b_x       a_y      b_y   c_x         a        b   c_y
0  May 15,2017  900.00  0.2%  1,900.00  1000000  0.2%  2,900.00  2000000  0.2%

k = np.arange(len(dfs)).astype(str)
df = pd.concat([x.set_index('date') for x in dfs], axis=1, join='inner', keys=k)
df.columns = df.columns.map('_'.join)
print (df)
                0_a   0_b       1_a      1_b   1_c       2_a      2_b   2_c
date                                                                       
May 15,2017  900.00  0.2%  1,900.00  1000000  0.2%  2,900.00  2000000  0.2%

Well for me only works adding the text "_helper" after in the php file like:

And to load automatically the helper in the folder aplication -> file autoload.php add in the array helper's the name without "_helper" like:

$autoload['helper'] = array('comunes');

And with that I can use all the helper's functions

Use request npm module and after call

var request = require('request');
request('http://www.google.com', function (error, response, body) {
  console.log('error:', error); // Print the error if one occurred
  console.log('statusCode:', response && response.statusCode); // Print the response status code if a response was received
  console.log('body:', body); // Print the HTML for the Google homepage.
});

For best practice also use some winston logger module or else simple console.log and then run your application like

npm start output.txt 

Result of above command will generate one txt file on root with all data which you have printed in console.log

normaly is better image store in public folder (because it has write permission already that you can use when I upload images to it)

public
    upload_media
         photos
            image.png


$image  = public_path() . '/upload_media/photos/image.png'; // destination path

view PHP

<img src="<?= $image ?>">

View blade

<img src="{{ $image }}">

On Windows 10 - This happened for me after the latest update in 2020.

What solved this issue for me was running the following in PowerShell

C:\>Install-Module -Name MicrosoftPowerBIMgmt

Adding on to the one mentioned by @abarnert

a better one is to catch the exception

import subprocess
try:
    py2output = subprocess.check_output(['python', 'py2.py', '-i', 'test.txt'],stderr= subprocess.STDOUT)  
    #print('py2 said:', py2output)
    print "here"
except subprocess.CalledProcessError as e:
    print "Calledprocerr"

this stderr= subprocess.STDOUT is for making sure you dont get the filenotfound error in stderr- which cant be usually caught in filenotfoundexception, else you would end up getting

python: can't open file 'py2.py': [Errno 2] No such file or directory

Infact a better solution to this might be to check, whether the file/scripts exist and then to run the file/script

The solution is also given by react, they advice you use useCallback which will return a memoize version of your function :

The 'fetchBusinesses' function makes the dependencies of useEffect Hook (at line NN) change on every render. To fix this, wrap the 'fetchBusinesses' definition into its own useCallback() Hook react-hooks/exhaustive-deps

useCallback is simple to use as it has the same signature as useEffect the difference is that useCallback returns a function. It would look like this :

 const fetchBusinesses = useCallback( () => {
        return fetch("theURL", {method: "GET"}
    )
    .then(() => { /* some stuff */ })
    .catch(() => { /* some error handling */ })
  }, [/* deps */])
  // We have a first effect thant uses fetchBusinesses
  useEffect(() => {
    // do things and then fetchBusinesses
    fetchBusinesses(); 
  }, [fetchBusinesses]);
   // We can have many effect thant uses fetchBusinesses
  useEffect(() => {
    // do other things and then fetchBusinesses
    fetchBusinesses();
  }, [fetchBusinesses]);

Like this

#if defined(LINUX) || defined(ANDROID)

 SqlConnection con = new SqlConnection(@"Some Connection String");
 SqlDataAdapter da = new SqlDataAdapter("ParaEmp_Select",con);
            da.SelectCommand.CommandType = CommandType.StoredProcedure;
            da.SelectCommand.Parameters.Add("@Contactid", SqlDbType.Int).Value = 123;
            DataTable dt = new DataTable();
            da.Fill(dt);
            dataGridView1.DataSource = dt;

With jQuery date format :

$.format.date(new Date(), 'yyyy/MM/dd HH:mm:ss');

Always use tax_query to get posts/products from a particular category or any other taxonomy. You can also get the products using ID/slug of particular taxonomy...

$the_query = new WP_Query( array(
    'post_type' => 'product',
    'tax_query' => array(
        array (
            'taxonomy' => 'product_cat',
            'field' => 'slug',
            'terms' => 'accessories',
        )
    ),
) );

while ( $the_query->have_posts() ) :
    $the_query->the_post();
    the_title(); echo "<br>";
endwhile;

To use the class ActionBarOverlayLayout you need to include this in the dependencies section of build.gradle file:

compile 'com.android.support:design:24.1.1'

Sync the project once again and then you will find no problem

Try next xml drawable code:

    <layer-list>
        <item android:top="-2dp" android:right="-2dp" android:left="-2dp">
            <shape>
                <solid android:color="@android:color/transparent" />
                <stroke
                    android:width="1dp"

yeah you will come across of various issues using HTML5 datepicker, it would work with some or might not be. I faced the same issue. Please check this DatePicker Demo, I solved my problem with this plugin. Its very good and flexible datepicker plugin with complete demo. It is completely compatible with mobile browsers too and can be integrated with jquery mobile too.

You cannot, due to security reasons.

Imagine:

<form name="foo" method="post" enctype="multipart/form-data">
    <input type="file" value="c:/passwords.txt">
</form>
<script>document.foo.submit();</script>

You don't want the websites you visit to be able to do this, do you? =)

In JavaScript, you call the replace method on the String object, e.g. "this is some sample text that i want to replace".replace("want", "dont want"), which will return the replaced string.

var text = "this is some sample text that i want to replace";
var new_text = text.replace("want", "dont want"); // new_text now stores the replaced string, leaving the original untouched

This is not possible from HTML on. The closest what you can get is the accept-charset attribute of the <form>. Only MSIE browser adheres that, but even then it is doing it wrong (e.g. CP1252 is actually been used when it says that it has sent ISO-8859-1). Other browsers are fully ignoring it and they are using the charset as specified in the Content-Type header of the response. Setting the character encoding right is basically fully the responsiblity of the server side. The client side should just send it back in the same charset as the server has sent the response in.

To the point, you should really configure the character encoding stuff entirely from the server side on. To overcome the inability to edit URIEncoding attribute, someone here on SO wrote a (complex) filter: Detect the URI encoding automatically in Tomcat. You may find it useful as well (note: I haven't tested it).

Update: Noted should be that the meta tag as given in your question is ignored when the content is been transferred over HTTP. Instead, the HTTP response Content-Type header will be used to determine the content type and character encoding. You can determine the HTTP header with for example Firebug, in the Net panel.

I ran into this on Mac as well, and it seems to be related to having an unfortunately similarly named "crypto" module (not sure what that is for) installed alongside of pycrypto via pip.

The fix seems to be removing both crypto and pycrypto with pip:

sudo pip uninstall crypto
sudo pip uninstall pycrypto

and reinstalling pycrypto:

sudo pip install pycrypto

Now it works as expected when I do something like:

from Crypto.Cipher import AES

Perhaps this is specific to .net core, I found DisplayName would not work but Display(Name=...) does. This may save someone else the troubleshooting involved :)

//using statements
using System;
using System.ComponentModel.DataAnnotations;  //needed for Display annotation
using System.ComponentModel;  //needed for DisplayName annotation

public class Whatever
{
    //Property
    [Display(Name ="Release Date")]
    public DateTime ReleaseDate { get; set; }
}


//cshtml file
@Html.DisplayNameFor(model => model.ReleaseDate)

Code:

List<String> list = new ArrayList<String>();

list.add("a");

JSONArray array = new JSONArray();

for (int i = 0; i < list.size(); i++) {
    array.put(list.get(i));
}
JSONObject obj = new JSONObject();

try {
    obj.put("result", array);
} catch (JSONException e) {
    e.printStackTrace();
}

No, there's no direct not operator. At least not the way you hope for.

You can use a zero-width negative lookahead, however:

\((?!2001)[0-9a-zA-z _\.\-:]*\)

The (?!...) part means "only match if the text following (hence: lookahead) this doesn't (hence: negative) match this. But it doesn't actually consume the characters it matches (hence: zero-width).

There are actually 4 combinations of lookarounds with 2 axes:

• lookbehind / lookahead : specifies if the characters before or after the point are considered
• positive / negative : specifies if the characters must match or must not match.

after some test: If you send an email to an outlook client, and the subject is >77 chars, and it needs to use "=?ISO" inside the subject (in my case because of accents) then OutLook will "cut" the subject in the middle of it and mesh it all that comes after, including body text, attaches, etc... all a mesh!

I have several examples like this one:

Subject: =?ISO-8859-1?Q?Actas de la obra N=BA.20100154 (Expediente N=BA.20100182) "NUEVA RED FERROVIARIA.=

TRAMO=20BEASAIN=20OESTE(Pedido=20PC10/00123-125),=20BEASAIN".?=

To:

As you see, in the subject line it cutted on char 78 with a "=" followed by 2 or 3 line feeds, then continued with the rest of the subject baddly.

It was reported to me from several customers who all where using OutLook, other email clients deal with those subjects ok.

If you have no ISO on it, it doesn't hurt, but if you add it to your subject to be nice to RFC, then you get this surprise from OutLook. Bit if you don't add the ISOs, then iPhone email will not understand it(and attach files with names using such characters will not work on iPhones).

Judging by the declaration and description of the startsWith Java function, the "most straight forward way" to implement it in VBA would either be with Left:

Public Function startsWith(str As String, prefix As String) As Boolean
    startsWith = Left(str, Len(prefix)) = prefix
End Function

Or, if you want to have the offset parameter available, with Mid:

Public Function startsWith(str As String, prefix As String, Optional toffset As Integer = 0) As Boolean

I found this helpful. http://jqr.github.com/2009/04/25/deploying-multiple-environments-on-heroku.html

I have added var for all the variables in the corrosponding javascript. That solved the problem in IE.

Previous Code

billableStatus = 1 ;
var classStr = $(this).attr("id").split("_");  
date = currentWeekDates[classStr[2]]; // Required    

activityNameId = "initialRows_" + classStr[1] + "_projectActivityName";
activityId = $("#"+activityNameId).val();        

var projectNameId = "initialRows_" + classStr[1] + "_projectName" ;
projectName = $("#"+projectNameId).val();        

var timeshitEntryId = "initialRows_"+classStr[1]+"_"+classStr[2];     
timeshitEntry = $("#"+timeshitEntryId).val();   

New Code

var billableStatus = 1 ;
var classStr = $(this).attr("id").split("_");  
var date = currentWeekDates[classStr[2]]; // Required    

var activityNameId = "initialRows_" + classStr[1] + "_projectActivityName";
var activityId = $("#"+activityNameId).val();        

var projectNameId = "initialRows_" + classStr[1] + "_projectName" ;
var projectName = $("#"+projectNameId).val();        

var timeshitEntryId = "initialRows_"+classStr[1]+"_"+classStr[2];     
var timeshitEntry = $("#"+timeshitEntryId).val();   

It looks like you were on the right path. Here is the one-liner you were looking for:

df.reset_index().T.drop_duplicates().T

But since there is no example data frame that produces the referenced error message Reindexing only valid with uniquely valued index objects, it is tough to say exactly what would solve the problem. if restoring the original index is important to you do this:

original_index = df.index.names
df.reset_index().T.drop_duplicates().reset_index(original_index).T

public void run() {
    byte[] buffer = new byte[256];  
    int bytes;                      

    while (true) {
        try {
            bytes = mmInStream.read(buffer);
            mHandler.obtainMessage(RECIEVE_MESSAGE, bytes, -1, buffer).sendToTarget();
        } catch (IOException e) {
            break;
        }
    }
}

If you actually create the buffer as per dirks suggestion, then:

  int readResult = read(socketFileDescriptor, buffer, BUFFER_SIZE);

may completely fill the buffer, possibly overwriting the terminating zero character which you depend on when extracting to a stringstream. You need:

  int readResult = read(socketFileDescriptor, buffer, BUFFER_SIZE - 1 );

If you're going to compile a 64bit version(x86_64) of php use: /usr/lib64/

For architectures (i386 ... i686) use /usr/lib/

I recommend compiling php to the same architecture as apache. As you're using a 64bit linux i asume your apache is also compiled for x86_64.

Not really, you have to assign a variable. So

    var bar = Stuff.Elements.Foo;
    bar.Name = "Bob Dylan";
    bar.Age = 68;
    bar.Location = "On Tour";
    bar.IsCool = True;

Or in C# 3.0:

    var bar = Stuff.Elements.Foo
    {
        Name = "Bob Dylan",
        Age = 68,
        Location = "On Tour",
        IsCool = True
    };

They are lists because you type them as lists in the dictionary:

bikes = {
    # Bike designed for children"
    "Trike": ["Trike", 20, 100],
    # Bike designed for everyone"
    "Kruzer": ["Kruzer", 50, 165]
    }

You should use the bike-class instead:

bikes = {
    # Bike designed for children"
    "Trike": Bike("Trike", 20, 100),
    # Bike designed for everyone"
    "Kruzer": Bike("Kruzer", 50, 165)
    }

This will allow you to get the cost of the bikes with bike.cost as you were trying to.

for bike in bikes.values():
    profit = bike.cost * margin
    print(bike.name + " : " + str(profit))

This will now print:

Kruzer : 33.0
Trike : 20.0

Since you're using ToFileTime, you'll want to use FromFileTime to go the other way. But note:

Ordinarily, the FromFileTime method restores a DateTime value that was saved by the ToFileTime method. However, the two values may differ under the following conditions:

If the serialization and deserialization of the DateTime value occur in different time zones. For example, if a DateTime value with a time of 12:30 P.M. in the U.S. Eastern Time zone is serialized, and then deserialized in the U.S. Pacific Time zone, the original value of 12:30 P.M. is adjusted to 9:30 A.M. to reflect the difference between the two time zones.

If the DateTime value that is serialized represents an invalid time in the local time zone. In this case, the ToFileTime method adjusts the restored DateTime value so that it represents a valid time in the local time zone.

If you don't care which long representation of a DateTime is stored, you can use Ticks as others have suggested (Ticks is probably preferable, depending on your requirements, since the value returned by ToFileTime seems to be in the context of the Windows filesystem API).

for Xcode 8:

What I do is run sudo du -khd 1 in the Terminal to see my file system's storage amounts for each folder in simple text, then drill up/down into where the huge GB are hiding using the cd command.

Ultimately you'll find the Users//Library/Developer/CoreSimulator/Devices folder where you can have little concern about deleting all those "devices" using iOS versions you no longer need. It's also safe to just delete them all, but keep in mind you'll lose data that's written to the device like sqlite files you may want to use as a backup version.

I once saved over 50GB doing this since I did so much testing on older iOS versions.

For me it was that I could not cluster my zookeeper.

A comprehansive comparison between diffreent formats made by me in this post- https://maxondev.com/serialization-performance-comparison-c-net-formats-frameworks-xmldatacontractserializer-xmlserializer-binaryformatter-json-newtonsoft-servicestack-text/

Just one sample from the post-

In matplotlib grey colors can be given as a string of a numerical value between 0-1.
For example c = '0.1'

Then you can convert your third variable in a value inside this range and to use it to color your points.
In the following example I used the y position of the point as the value that determines the color:

from matplotlib import pyplot as plt

x = [1, 2, 3, 4, 5, 6, 7, 8, 9]
y = [125, 32, 54, 253, 67, 87, 233, 56, 67]

color = [str(item/255.) for item in y]

plt.scatter(x, y, s=500, c=color)

plt.show()

You can find if the textbox is disabled using is method by passing :disabled selector to it. Try this.

if($('textbox').is(':disabled')){
     //textbox is disabled
}

The normal way to plot plots with points in different colors in matplotlib is to pass a list of colors as a parameter.

E.g.:

import matplotlib.pyplot
matplotlib.pyplot.scatter([1,2,3],[4,5,6],color=['red','green','blue'])

When you have a list of lists and you want them colored per list. I think the most elegant way is that suggesyted by @DSM, just do a loop making multiple calls to scatter.

But if for some reason you wanted to do it with just one call, you can make a big list of colors, with a list comprehension and a bit of flooring division:

import matplotlib
import numpy as np

X = [1,2,3,4]
Ys = np.array([[4,8,12,16],
      [1,4,9,16],
      [17, 10, 13, 18],
      [9, 10, 18, 11],
      [4, 15, 17, 6],
      [7, 10, 8, 7],
      [9, 0, 10, 11],
      [14, 1, 15, 5],
      [8, 15, 9, 14],
       [20, 7, 1, 5]])
nCols = len(X)  
nRows = Ys.shape[0]

colors = matplotlib.cm.rainbow(np.linspace(0, 1, len(Ys)))

cs = [colors[i//len(X)] for i in range(len(Ys)*len(X))] #could be done with numpy's repmat
Xs=X*nRows #use list multiplication for repetition
matplotlib.pyplot.scatter(Xs,Ys.flatten(),color=cs)

cs = [array([ 0.5,  0. ,  1. ,  1. ]),
 array([ 0.5,  0. ,  1. ,  1. ]),
 array([ 0.5,  0. ,  1. ,  1. ]),
 array([ 0.5,  0. ,  1. ,  1. ]),
 array([ 0.28039216,  0.33815827,  0.98516223,  1.        ]),
 array([ 0.28039216,  0.33815827,  0.98516223,  1.        ]),
 array([ 0.28039216,  0.33815827,  0.98516223,  1.        ]),
 array([ 0.28039216,  0.33815827,  0.98516223,  1.        ]),
 ...
 array([  1.00000000e+00,   1.22464680e-16,   6.12323400e-17,
          1.00000000e+00]),
 array([  1.00000000e+00,   1.22464680e-16,   6.12323400e-17,
          1.00000000e+00]),
 array([  1.00000000e+00,   1.22464680e-16,   6.12323400e-17,
          1.00000000e+00]),
 array([  1.00000000e+00,   1.22464680e-16,   6.12323400e-17,
          1.00000000e+00])]

The safest way IMO is to point at the file in your run/debug config

-Dlog4j.configuration=file:mylogging.properties

! Be aware: when using the eclipse launch configurations the specification of the file: protocol is mandatory.

In this way the logger will not catch any logging.properties that come before in the classpath nor the default one in the JDK.

Also, consider actually use the log4j.xml which has a richer expression syntax and will allow more things (log4j.xml tahe precedence over log4j.properties.

Fears of performance or bloat are not good reason to forgo C++. Every language has its potential pitfalls and trade offs - good programmers learn about these and where necessary develop coping strategies, poor programmers will fall foul and blame the language.

Interpreted Python is in many ways considered to be a "slow" language, but for non-trivial tasks a skilled Python programmer can easily produce code that executes faster than that of an inexperienced C developer.

In my industry, video games, we write high performance code in C++ by avoiding things such as RTTI, exceptions, or virtual-functions in inner loops. These can be extremely useful but have performance or bloat problems that it's desirable to avoid. If we were to go a step further and switch entirely to C we would gain little and lose the most useful constructs of C++.

The biggest practical reason for preferring C is that support is more widespread than C++. There are many platforms, particularly embedded ones, that do not even have C++ compilers.

There is also the matter of compatibility for vendors. While C has a stable and well-defined ABI (Application Binary Interface) C++ does not. The ABI in C++ is more complicated due to such things as vtables and constructurs/destructors so is implemented differently with every vendor, and even versions of a vendors toolchain.

In real-terms this means you cannot take a library generated by one compiler and link it with code or a library from another which creates a nightmare for distributed projects or middleware providers of binary libraries.

For simply checking against Object or Array without additional function call (speed).

isArray()

isArray = function(a) {
    return (!!a) && (a.constructor === Array);
};
console.log(isArray(        )); // false
console.log(isArray(    null)); // false
console.log(isArray(    true)); // false
console.log(isArray(       1)); // false
console.log(isArray(   'str')); // false
console.log(isArray(      {})); // false
console.log(isArray(new Date)); // false
console.log(isArray(      [])); // true

isObject()

isObject = function(a) {
    return (!!a) && (a.constructor === Object);
};
console.log(isObject(        )); // false
console.log(isObject(    null)); // false
console.log(isObject(    true)); // false
console.log(isObject(       1)); // false
console.log(isObject(   'str')); // false
console.log(isObject(      [])); // false
console.log(isObject(new Date)); // false
console.log(isObject(      {})); // true

console.log has nothing to do with jQuery.

It logs a message to a debugging console, such as Firebug.

If you are using form control then the simplest way to do this:

this.FormName.get('ControlName').setValue(value);

This will give you the deadline :

select id,  
       title,
       created_at + interval '1' day * claim_window as deadline
from projects

Alternatively the function make_interval can be used:

select id,  
       title,
       created_at + make_interval(days => claim_window) as deadline
from projects

To get all projects where the deadline is over, use:

select *
from (
  select id, 
         created_at + interval '1' day * claim_window as deadline
  from projects
) t
where localtimestamp at time zone 'UTC' > deadline

Try using document.getElementById("myForm") instead of document.myForm.

<script>
var auto_refresh = setInterval(function() { submitform(); }, 10000);

function submitform()
{
  alert('test');
  document.getElementById("myForm").submit();
}
</script>

At the beginning of your loading script, just make your

visible through css [display:block;] and make the rest of the page invisible through css[display:none;].

Once the loading is done, just make the loading invisible and the page visible again with the same technique. You can use the document.getElementById() to select the divs you want to change the display.

Edit: Here's what it would sort of look like. When the body finishes loading, it will call the javascript function that will change the display values of the different elements. By default, your style would be to have the page not visible the loading visible.

<head>
    <style>
        #page{
            display: none;
        }
        #loading{
            display: block;
        }
    </style>
    <script>
        function myFunction()
        {
            document.getElementById("page").style.display = "block";
            document.getElementById("loading").style.display = "none";
        }
    </script>
</head>

<body onload="myFunction()">
    <div id="page">

    </div>
    <div id="loading">

    </div>
</body>

TLDR

=(A1/86400)+25569

...and the format of the cell should be date.

If it doesn't work for you

• If you get a number you forgot to format the output cell as a date.
• If you get ##### you probably don't have a real Unix time. Check your timestamps in https://www.epochconverter.com/. Try to divide your input by 10, 100, 1000 or 10000**
• You work with timestamps outside Excel's (very extended) limits.
• You didn't replace A1 with the cell containing the timestamp ;-p

Explanation

Unix system represent a point in time as a number. Specifically the number of seconds* since a zero-time called the Unix epoch which is 1/1/1970 00:00 UTC/GMT. This number of seconds is called "Unix timestamp" or "Unix time" or "POSIX time" or just "timestamp" and sometimes (confusingly) "Unix epoch".

In the case of Excel they chose a different zero-time and step (because who wouldn't like variety in technical details?). So Excel counts days since 24 hours before 1/1/0000 UTC/GMT. So 25569 corresponds to 1/1/1970 00:00 UTC/GMT and 25570 to 2/1/1970 00:00.

Now please note that we have 86400 seconds per day (24 hours x60 minutes each x60 seconds) and you can understand what this formula does: A1/86400 converts seconds to days and +25569 adjusts for the offset between what is time-zero for Unix and what is time-zero for Excel.

By the way DATE(1970,1,1) will helpfully return 25569 for you in case you forget all this so a more "self-documenting" way to write our formula is:

=A1/(24*60*60) + DATE(1970,1,1)

P.S.: All these were already present in other answers and comments just not laid out as I like them and I don't feel it's OK to edit the hell out of another answer.

*: that's almost correct because you should not count leap seconds

**: E.g. in the case of this question the number was number of milliseconds since the the Unix epoch.

Next release of ASP.NET MVC (available in January or so) should have MSBuild task that compiles views, so you might want to wait.

Change the function that you get one single Result=[array, listp, freep]. So there is only one result to be displayed

ffmpeg -i <input.mp4> -b:v 2048k -s 1000x600 -fs 2048k -vcodec mpeg4 -acodec copy <output.mp4>

• -i input file

• -b:v videobitrate of output video in kilobytes (you have to try)

• -s dimensions of output video

• -fs FILESIZE of output video in kilobytes

• -vcodec videocodec (use ffmpeg -codecs to list all available codecs)

• -acodec audio codec for output video (only copy the audiostream, don't temper)

Use this

try this

SimpleDateFormat dateFormat = new SimpleDateFormat("dd-MM-yyyy HH:mm:ss");
String string  = dateFormat.format(new Date());

git push --all --prune --dry-run

By doing so like the above, git will provide you with a list of what would happen if the below command is executed.

Then run the following command to remove all branches from the remote repo that are not in your local repo:

git push --all --prune

Looking at the code I found the following differences between jquery.js and jquery.slim.js:

In the jquery.slim.js, the following features are removed:

1. jQuery.fn.extend
2. jquery.fn.load
3. jquery.each // Attach a bunch of functions for handling common AJAX events
4. jQuery.expr.filters.animated
5. ajax settings like jQuery.ajaxSettings.xhr, jQuery.ajaxPrefilter, jQuery.ajaxSetup, jQuery.ajaxPrefilter, jQuery.ajaxTransport, jQuery.ajaxSetup
6. xml parsing like jQuery.parseXML,
7. animation effects like jQuery.easing, jQuery.Animation, jQuery.speed

I guess you'll need absolute position

.vertical_banner {position:relative;}
#bottom_link{position:absolute; bottom:0;}

It's really easy to do: reliable and not messy:

        Try
            Clients.Client.Send(BufferByte)
        Catch verror As Exception
            BufferString = verror.ToString
        End Try
        If BufferString <> "" Then
            EventLog.Text &= "User disconnected: " + vbNewLine
            Clients.Close()
        End If

I got this error because i was using a variable in component.html which was not declared in component.ts. Once I removed the part in HTML, this error was gone.

On Windows, line.separator is a CR/LF combination (reference here).

The Java String.split() method takes a regular expression. So I think there's some confusion here.

Just for the record in history!

I've come up with a solution for my own work from 5-6 years ago, which is Gradext ( pure javascript and pure css, no dependency ) .

The technical explanation is you can create an element like this:

<span>A</span>

now if you want to make a gradient on text, you need to create some multiple layers, each individually specifically colored and the spectrum created will illustrate the gradient effect.

for example look at this is the word lorem inside of a <span> and will cause a horizontal gradient effect ( check the examples ):

 <span data-i="0" style="color: rgb(153, 51, 34);">L</span>
 <span data-i="1" style="color: rgb(154, 52, 35);">o</span>
 <span data-i="2" style="color: rgb(155, 53, 36);">r</span>
 <span data-i="3" style="color: rgb(156, 55, 38);">e</span>
 <span data-i="4" style="color: rgb(157, 56, 39);">m</span>

and you can continue doing this pattern for a long time and long paragraph as well.

But!

What if you want to create a vertical gradient effect on texts?

Then there's another solution which could be helpful. I will describe in details.

Assuming our first <span> again. but the content shouldn't be the letters individually; the content should be the whole text, and now we're going to copy the same ??<span> again and again ( count of spans will define the quality of your gradient, more span, better result, but poor performance ). have a look at this:

<span data-i="6" style="color: rgb(81, 165, 39); overflow: hidden; height: 11.2px;">Lorem ipsum dolor sit amet, tincidunt ut laoreet dolore magna aliquam erat volutpat.</span>
<span data-i="7" style="color: rgb(89, 174, 48); overflow: hidden; height: 12.8px;">Lorem ipsum dolor sit amet, tincidunt ut laoreet dolore magna aliquam erat volutpat.</span>
<span data-i="8" style="color: rgb(97, 183, 58); overflow: hidden; height: 14.4px;">Lorem ipsum dolor sit amet, tincidunt ut laoreet dolore magna aliquam erat volutpat.</span>
<span data-i="9" style="color: rgb(105, 192, 68); overflow: hidden; height: 16px;">Lorem ipsum dolor sit amet, tincidunt ut laoreet dolore magna aliquam erat volutpat.</span>
<span data-i="10" style="color: rgb(113, 201, 78); overflow: hidden; height: 17.6px;">Lorem ipsum dolor sit amet, tincidunt ut laoreet dolore magna aliquam erat volutpat.</span>
<span data-i="11" style="color: rgb(121, 210, 88); overflow: hidden; height: 19.2px;">Lorem ipsum dolor sit amet, tincidunt ut laoreet dolore magna aliquam erat volutpat.</span>

Again, But!

what if you want to make these gradient effects to move and create an animation out of it?

well, there's another solution for it too. You should definitely check animation: true or even .hoverable() method which will lead to a gradient to start based on cursor position! ( sounds cool xD )

this is simply how we're creating gradients ( linear or radial ) on texts. If you liked the idea or want to know more about it, you should check the links provided.

Maybe this is not the best option, maybe not the best performant way to do this, but it will open up some space to create exciting and delightful animations to inspire some other people for a better solution.

It will allow you to use gradient style on texts, which is supported by even IE8!

Here you can find a working live demo and the original repository is here on GitHub as well, open source and ready to get some updates ( :D )

This is my first time ( yeah, after 5 years, you've heard it right ) to mention this repository anywhere on the Internet, and I'm excited about that!

[Update - 2019 August:] Github removed github-pages demo of that repository because I'm from Iran! Only the source code is available here tho...

A bit of a hack, but this gives the effect of a multi-line select, puts in a gray bgcolor for your multi line, and if you select any of the gray text, it selects the first of the grouping. Kinda clever I'd say :) The first option also shows how you can put a title tag in for an option as well.

 function SelectFirst(SelVal) {_x000D_
   var arrSelVal = SelVal.split(",")_x000D_
   if (arrSelVal.length > 1) {_x000D_
     Valuetoselect = arrSelVal[0];_x000D_
     document.getElementById("select1").value = Valuetoselect;_x000D_
   }_x000D_
 }

<select name="select1" id="select1" onchange="SelectFirst(this.value)">_x000D_
  <option value="1" title="this is my long title for the yes option">Yes</option>_x000D_
  <option value="2">No</option>_x000D_
  <option value="2,1" style="background:#eeeeee">&nbsp;&nbsp;&nbsp;This is my description for the no option</option>_x000D_
  <option value="2,2" style="background:#eeeeee">&nbsp;&nbsp;&nbsp;This is line 2 for the no option</option>_x000D_

Reading through the answers here the common named reasons are that one cannot iterate through the tree or that the tree does not assume the similar interface to other STL containers and one could not use STL algorithms with such tree structure.

Having that in mind I tried to design my own tree data structure which will provide STL-like interface and will be usable with existing STL algorthims as much as possible.

My idea was that the tree must be based on the existing STL containers and that it must not hide the container, so that it will be accessible to use with STL algorithms.

The other important feature the tree must provide is the traversing iterators.

Here is what I was able to come up with: https://github.com/cppfw/utki/blob/master/src/utki/tree.hpp

And here are the tests: https://github.com/cppfw/utki/blob/master/tests/tree/tests.cpp

Generally, when you create an index on a table, database will automatically use that index while searching for data in that table. You don't need to do anything about that.

However, in MSSQL, you can specify an index hint which can specify that a particular index should be used to execute this query. More information about this can be found here.

Index hint is also seems to be available for MySQL. Thanks to Tudor Constantine.

You can use php in the style sheet. Just remember to set header("Content-type: text/css") in the style.php (or whatever then name is) file

Neither of these approaches (npm link or package.json file dependency) work if the local module has peer dependencies that you only want to install in your project's scope.

For example:

/local/mymodule/package.json:
  "name": "mymodule",
  "peerDependencies":
  {
    "foo": "^2.5"
  }

/dev/myproject/package.json:
  "dependencies":
  {
    "mymodule": "file:/local/mymodule",
    "foo": "^2.5"
  }

In this scenario, npm sets up myproject's node_modules/ like this:

/dev/myproject/node_modules/
  foo/
  mymodule -> /local/mymodule

When node loads mymodule and it does require('foo'), node resolves the mymodule symlink, and then only looks in /local/mymodule/node_modules/ (and its ancestors) for foo, which it doen't find. Instead, we want node to look in /local/myproject/node_modules/, since that's where were running our project from, and where foo is installed.

So, we either need a way to tell node to not resolve this symlink when looking for foo, or we need a way to tell npm to install a copy of mymodule when the file dependency syntax is used in package.json. I haven't found a way to do either, unfortunately :(

In my code, when I got the error, I checked the possible source, In a line, I had typed a beginning \[ and an ending \] due to which the error of missing $ appeared though I tried using $ for both the brackets. Removing the brackets or using $[$ instead of $\[$ solved my problem. If you've something like that, try altering.

The accepted solution from Dallas was working for us if we use Load Balancer on the Citrix Netscaler (without WAF policy).

The download of the file doesn't work through the LB of the Netscaler when it is associated with WAF as the current scenario (Content-length not being correct) is a RFC violation and AppFW resets the connection, which doesn't happen when WAF policy is not associated.

So what was missing was:

Response.End();

Just another take, this is what native JavaScript functions Map and Reduce were built for (Map and Reduce are powerhouses in many languages).

var traveler = [{description: 'Senior', Amount: 50},
                {description: 'Senior', Amount: 50},
                {description: 'Adult', Amount: 75},
                {description: 'Child', Amount: 35},
                {description: 'Infant', Amount: 25}];

function amount(item){
  return item.Amount;
}

function sum(prev, next){
  return prev + next;
}

traveler.map(amount).reduce(sum);
// => 235;

// or use arrow functions
traveler.map(item => item.Amount).reduce((prev, next) => prev + next);

Note: by making separate smaller functions we get the ability to use them again.

// Example of reuse.
// Get only Amounts greater than 0;

// Also, while using Javascript, stick with camelCase.
// If you do decide to go against the standards, 
// then maintain your decision with all keys as in...

// { description: 'Senior', Amount: 50 }

// would be

// { Description: 'Senior', Amount: 50 };

var travelers = [{description: 'Senior', amount: 50},
                {description: 'Senior', amount: 50},
                {description: 'Adult', amount: 75},
                {description: 'Child', amount: 35},
                {description: 'Infant', amount: 0 }];

// Directly above Travelers array I changed "Amount" to "amount" to match standards.

function amount(item){
  return item.amount;
}

travelers.filter(amount);
// => [{description: 'Senior', amount: 50},
//     {description: 'Senior', amount: 50},
//     {description: 'Adult', amount: 75},
//     {description: 'Child', amount: 35}];
//     Does not include "Infant" as 0 is falsey.

HashMap is unordered per the second line of the documentation:

This class makes no guarantees as to the order of the map; in particular, it does not guarantee that the order will remain constant over time.

Perhaps you can do as aix suggests and use a LinkedHashMap, or another ordered collection. This link can help you find the most appropriate collection to use.

I ended up doing something like this for AngularJS in case someone stumbles across this question:

const imageElem = angular.element('#awardImg');

if (imageElem[0].files[0])
    vm.award.imageElem = imageElem;
    vm.award.image = imageElem[0].files[0];

And then:

if (vm.award.imageElem)
    $('#awardImg').replaceWith(vm.award.imageElem);
    delete vm.award.imageElem;

wxLua has three sleep functions:

local wx = require 'wx'
wx.wxSleep(12)   -- sleeps for 12 seconds
wx.wxMilliSleep(1200)   -- sleeps for 1200 milliseconds
wx.wxMicroSleep(1200)   -- sleeps for 1200 microseconds (if the system supports such resolution)

While working with selected cells as shown by @tbur can be useful, it's also not the only option available.

You can use Range() like so:

If Worksheets("Sheet1").Range("A1").MergeCells Then
  Do something
Else
  Do something else
End If

Or:

If Worksheets("Sheet1").Range("A1:C1").MergeCells Then
  Do something
Else
  Do something else
End If

Alternately, you can use Cells():

If Worksheets("Sheet1").Cells(1, 1).MergeCells Then
  Do something
Else
  Do something else
End If

To use video extensions that are MKV. You should use video, not source

For example :

  <!-- mkv -->
  <video width="320" height="240" controls src="assets/animation.mkv"></video>
<!-- mp4 -->
  <video width="320" height="240" controls>
    <source src="assets/animation.mp4" type="video/mp4" />
  </video>

I think you have a couple of options here.

you could store the last Exception in the Session and retrieve it from your custom error page; or you could just redirect to your custom error page within the Application_error event. If you choose the latter, you want to make sure you use the Server.Transfer method.

Android needs to be compiled for every hardware plattform / every device model seperatly with the specific drivers etc. If you manage to do that you need also break the security arrangements every manufacturer implements to prevent the installation of other software - these are also different between each model / manufacturer. So it is possible at in theory, but only there :-)

String is immutable, meaning that when you perform an operation on a String you are really creating a whole new String.

StringBuffer is mutable, and you can append to it as well as reset its length to 0.

In practice, the compiler seems to use StringBuffer during String concatenation for performance reasons.

Compile is the process of creating an executable program from code written in a compiled programming language. Compiling allows the computer to run and understand the program without the need of the programming software used to create it. When a program is compiled it is often compiled for a specific platform (e.g. IBM platform) that works with IBM compatible computers, but not other platforms (e.g. Apple platform). The first compiler was developed by Grace Hopper while working on the Harvard Mark I computer. Today, most high-level languages will include their own compiler or have toolkits available that can be used to compile the program. A good example of a compiler used with Java is Eclipse and an example of a compiler used with C and C++ is the gcc command. Depending on how big the program is it should take a few seconds or minutes to compile and if no errors are encountered while being compiled an executable file is created.check this information

$response is instance of PSR-7 ResponseInterface. For more details see https://www.php-fig.org/psr/psr-7/#3-interfaces

getBody() returns StreamInterface:

/**
 * Gets the body of the message.
 *
 * @return StreamInterface Returns the body as a stream.
 */
public function getBody();

StreamInterface implements __toString() which does

Reads all data from the stream into a string, from the beginning to end.

Therefore, to read body as string, you have to cast it to string:

$stringBody = (string) $response->getBody()

Gotchas

1. json_decode($response->getBody() is not the best solution as it magically casts stream into string for you. json_decode() requires string as 1st argument.
2. Don't use $response->getBody()->getContents() unless you know what you're doing. If you read documentation for getContents(), it says: Returns the remaining contents in a string. Therefore, calling getContents() reads the rest of the stream and calling it again returns nothing because stream is already at the end. You'd have to rewind the stream between those calls.

here, 2 in binary(8 bit) is 00000010 and its 1's complement is 11111101, subtract 1 from that 1's complement we get 11111101-1 = 11111100, here the sign is - as 8th character (from R to L) is 1 find 1's complement of that no. i.e. 00000011 = 3 and the sign is negative that's why we get -3 here.

I assume curl is reading the proxy address from the environment variable http_proxy and that the variable should keep its value. Then in a shell like bash, export http_proxy=''; before a command (or in a shell script) would temporarily change its value.

You can also do it without subclassing UITextView. Have a look at my answer to How do I size a UITextView to its content on iOS 7?

Use the value of this expression:

to update the constant of the textView's height UILayoutConstraint.

I was having this same problem in a web app using Microsoft Visual Studio 2019, Asp.Net 3.1 and Bootstrap 4.5. I had a modal form open to add a new staff person (only a few input fields) and the Add Staff button would invoke an ajax call to create the staff records in the database. Upon successful return the code would refresh the partial razor page of staff (so the new staff person would appear in the list).

Just before the refresh I would close the Add Staff modal and display a Please Wait modal which only had a bootstrap spinner button on it. What happened is that the Please Wait modal would stay displayed and not close after the staff refresh and the modal('hide') function on this modal was called. Some times the modal would disappear but the modal backdrop would remain effectively locking the Staff List form.

Since Bootstrap has issues with multiple modals open at once, I thought maybe the Add Staff modal was still open when the Please Wait modal was displayed and this was causing problems. I made a function to display the Please Wait modal and do the refresh, and called it using the Javascript function setTimeout() to wait 1/2 second after closing/hiding the Add Staff modal:

//hide the modal form
$("#addNewStaffModal").modal('hide');
setTimeout(RefreshStaffListAfterAddingStaff, 500); //wait for 1/2 second

Here is the code for the refresh function:

function RefreshStaffListAfterAddingStaff() {
    // refresh the staff list in our partial view

    //show the please wait message
    $('#PleaseWaitModal').modal('show');

    //refresh the partial view
    $('#StaffAccountsPartialView').load('StaffAccounts?handler=StaffAccountsPartial',
        function (data, status, jqXGR) {

            //hide the wait modal
            $('#PleaseWaitModal').modal('hide');
            // enable all the fields on our form
            $("#StaffAccountsForm :input").prop("disabled", false);

            //scroll to the top of the staff list window
            window.scroll({
                top: 0,
                left: 0,
                behavior: 'smooth'
            });

        });
}

This seems to have totally solved my problem!

What about CassandraDB, Project Voldemort, TokyoCabinet?

The best solution is to use async Task. You should avoid async void for several reasons, one of which is composability.

If the method cannot be made to return Task (e.g., it's an event handler), then you can use SemaphoreSlim to have the method signal when it is about to exit. Consider doing this in a finally block.

There is an easy way to sort a dictionary.

According to your question,

The solution is :

c={2:3, 1:89, 4:5, 3:0}
y=sorted(c.items())
print y

(Where c,is the name of your dictionary.)

This program gives the following output:

[(1, 89), (2, 3), (3, 0), (4, 5)]

like u wanted.

Another example is:

d={"John":36,"Lucy":24,"Albert":32,"Peter":18,"Bill":41}
x=sorted(d.keys())
print x

Gives the output:['Albert', 'Bill', 'John', 'Lucy', 'Peter']

y=sorted(d.values())
print y

Gives the output:[18, 24, 32, 36, 41]

z=sorted(d.items())
print z

Gives the output:

[('Albert', 32), ('Bill', 41), ('John', 36), ('Lucy', 24), ('Peter', 18)]

Hence by changing it into keys, values and items , you can print like what u wanted.Hope this helps!

\df+ in psql gives you the sourcecode.

Simple, edit /etc/nginx/nginx.conf and remove comment from

#server_tokens off;

Search for http section.

This is a simple approach if you don't have much code changes:

1. git stash
2. git stash apply
3. remove the files/code you don't want to commit
4. commit the remaining files/code you do want

Then if you want the code you removed (bits you didn't commit) in a separate commit or another branch, then while still on this branch do:

5. git stash apply
6. git stash

With step 5 as you already applied the stash and committed the code you did want in step 4, the diff and untracked in the newly applied stash is just the code you removed in step 3 before you committed in step 4.

As such step 6 is a stash of the code you didn't [want to] commit, as you probably don't really want to lose those changes right? So the new stash from step 6 can now be committed to this or any other branch by doing git stash apply on the correct branch and committing.

Obviously this presumes you do the steps in one flow, if you stash at any other point in these steps you'll need to note the stash ref for each step above (rather than just basic stash and apply the most recent stash).

Maybe it's too late for an answer to this question but i think i have found a fix for it, what i noticed is within the info.plist file > JVMoption (Mac) with in the application package there is two version of java i.e it was showing "1.6*,1.7+" so i just changed it to "1.8*" which is my current java version and now its working for me

Other answers were not working for me so i did some changes. Hope this will help

$('#iframe').on("load", function() {
    var iframe = $(window.top.document).find("#iframe");
    iframe.height(iframe[0].ownerDocument.body.scrollHeight+'px' );
});

Check out some of the answers to this question - I think it might apply to yours:

how to run click function after default behaviour of a element

I think you're running into an inconsistency in the browser implementation of the onclick function. Some choose to toggle the checkbox before the event is fired and some after.

I know this is well answered, but if you're interested, I wrote a library that makes executing commands much easier.

Check it out here: https://github.com/twitchax/Sheller.

To kill a process by a specific keyword you could create an alias in ~/.bashrc (linux) or ~/.bash_profile (mac).

alias killps="kill -9 `ps -ef | grep '[k]eyword' | awk '{print $2}'`"

You can also try this, after injecting $window service.

$window.location.reload();

Use a white space to match all descendants of an element:

div.dropdown * {
    color: red;
}

x y matches every element y that is inside x, however deeply nested it may be - children, grandchildren and so on.

The asterisk * matches any element.

For Developer certificate, you need to create a developer .mobileprovision profile and install add it to your XCode. In case you want to distribute the app using an adhoc distribution profile you will require AdHoc Distribution certificate and private key installed in your keychain.

If you have not created the cert, here are steps to create it. Incase it has already been created by someone in your team, ask him to share the cert and private key. If that someone is no longer in your team then you can revoke the cert from developer account and create new.

This solution may not be optimal or pretty, but it works. It reads in an input file line by line, writing each line out to a temporary output file. Whenever it encounters a line that matches what you are looking for, it skips writing that one out. It then renames the output file. I have omitted error handling, closing of readers/writers, etc. from the example. I also assume there is no leading or trailing whitespace in the line you are looking for. Change the code around trim() as needed so you can find a match.

File inputFile = new File("myFile.txt");
File tempFile = new File("myTempFile.txt");

BufferedReader reader = new BufferedReader(new FileReader(inputFile));
BufferedWriter writer = new BufferedWriter(new FileWriter(tempFile));

String lineToRemove = "bbb";
String currentLine;

while((currentLine = reader.readLine()) != null) {
    // trim newline when comparing with lineToRemove
    String trimmedLine = currentLine.trim();
    if(trimmedLine.equals(lineToRemove)) continue;
    writer.write(currentLine + System.getProperty("line.separator"));
}
writer.close(); 
reader.close(); 
boolean successful = tempFile.renameTo(inputFile);

To use the second way, add 1:

print $#arr + 1; # Second way to print array size

Replace the desired hyphen with an underscore; it will automatically be rendered as a hyphen:

@Html.ActionLink("Edit", "edit", "markets",
    new { id = 1 },
    new {@class="ui-btn-right", data_icon="gear"})

becomes:

<form action="markets/Edit/1" class="ui-btn-right" data-icon="gear" .../>

playersList.get(0)

Java has limited operator polymorphism. So you use the get() method on List objects, not the array index operator ([])

Thank you for this example, SPRBRN. It helped me. And I can suggest the mixin, which I've used based on the code given above:

//multi-column-list( fixed columns width)
  @mixin multi-column-list($column-width, $column-rule-style) {
  -webkit-column-width: $column-width;
  -moz-column-width: $column-width;
  -o-column-width: $column-width;
  -ms-column-width: $column-width;
  column-width: $column-width;

  -webkit-column-rule-style: $column-rule-style;
  -moz-column-rule-style: $column-rule-style;
  -o-column-rule-style: $column-rule-style;
  -ms-column-rule-style: $column-rule-style;
  column-rule-style: $column-rule-style;
 }

Using:

   @include multi-column-list(250px, solid);

onActivityCreated() - Deprecated

onActivityCreated() is now deprecated as Fragments Version 1.3.0-alpha02

The onActivityCreated() method is now deprecated. Code touching the fragment's view should be done in onViewCreated() (which is called immediately before onActivityCreated()) and other initialization code should be in onCreate(). To receive a callback specifically when the activity's onCreate() is complete, a LifeCycleObserver should be registered on the activity's Lifecycle in onAttach(), and removed once the onCreate() callback is received.

Detailed information can be found here

It is crazy that no one has mentioned this elegant solution. This should be the accepted answer.

SplashActivity -> AuthActivity -> DashActivity

if (!sessionManager.isLoggedIn()) {
    Intent intent = new Intent(context, AuthActivity.class);
    intent.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
    context.startActivity(intent);
    finish();
} else {
   Intent intent = new Intent(context, DashActivity.class);
   context.startActivity(intent);
    finish();
}

The key here is to use intent.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY); for the intermediary Activity. Once that middle link is broken, the DashActivity will the first and last in the stack.

android:noHistory="true" is a bad solution, as it causes problems when relying on the Activity as a callback e.g onActivityResult. This is the recommended solution and should be accepted.

You should not ever want to do this. Select * should not be used as the basis for an insert as the columns may get moved around and break your insert (or worse not break your insert but mess up your data. Suppose someone adds a column to the table in the select but not the other table, you code will break. Or suppose someone, for reasons that surpass understanding but frequently happen, decides to do a drop and recreate on a table and move the columns around to a different order. Now your last_name is is the place first_name was in originally and select * will put it in the wrong column in the other table. It is an extremely poor practice to fail to specify columns and the specific mapping of one column to the column you want in the table you are interested in.

Right now you may have several problems, first the two structures don't match directly or second the table being inserted to has an identity column and so even though the insertable columns are a direct match, the table being inserted to has one more column than the other and by not specifying the database assumes you are going to try to insert to that column. Or you might have the same number of columns but one is an identity and thus can't be inserted into (although I think that would be a different error message).

Back references can find interesting solutions here. This regex:

([a-z]+).*(\1)

will find the longest repeated sequence.

This one will find a sequence of 3 letters that is repeated:

([a-z]{3}).*(\1)

A naive, CPU-intensive method to block execution for a number of milliseconds:

/**
* Delay for a number of milliseconds
*/
function sleep(delay) {
    var start = new Date().getTime();
    while (new Date().getTime() < start + delay);
}

For Database first Aproach:

We can still set it in a constructor, by override the ContextName.Context.tt T4 Template this way:

<#=Accessibility.ForType(container)#> partial class <#=code.Escape(container)#> : DbContext
{
    public <#=code.Escape(container)#>()
        : base("name=<#=container.Name#>")
    {
        Database.CommandTimeout = 180;
<#
if (!loader.IsLazyLoadingEnabled(container))
{
#>
        this.Configuration.LazyLoadingEnabled = false;
<#
}

Database.CommandTimeout = 180; is the acutaly change.

The generated output is this:

public ContextName() : base("name=ContextName")
{
    Database.CommandTimeout = 180;
}

If you change your Database Model, this template stays, but the actualy class will be updated.

You can try this code for converting bytes from packet to a null-terminated string and store to "string" variable for processing.

const int buffer_size = 2048;
// variable for storing buffer as printable HEX string
char data[buffer_size*2];
// receive message from socket
int ret = recvfrom(sock, buffer, sizeofbuffer, 0, reinterpret_cast<SOCKADDR *>(&from), &size);
// bytes converting cycle
for (int i=0,j=0; i<ret; i++,j+=2){ 
    char res[2]; 
    itoa((buffer[i] & 0xFF), res, 16);
        if (res[1] == 0) {
            data[j] = 0x30; data[j+1] = res[0];
        }else {
            data[j] = res[0]; data[j + 1] = res[1];
        }
}
// Null-Terminating the string with converted buffer
data[(ret * 2)] = 0;

When we send message with hex bytes 0x01020E0F, variable "data" had char array with string "01020e0f".

Please use Spring Tool Suite (Eclipse-based development environment that is customized for developing Spring applications).
Create a Spring Starter Project, it will create the directory structure for you with the spring boot maven dependencies.

The purpose of this answer is not to add anything new that the others don't already cover, but to extend @Kevin Loney's answer.

You could use the lightweight declaration:

int *ary = new int[SizeX*SizeY]

and access syntax will be:

ary[i*SizeY+j]     // ary[i][j]

but this is cumbersome for most, and can lead to confusion. So, you can define a macro as follows:

#define ary(i, j)   ary[(i)*SizeY + (j)]

Now you can access the array using the very similar syntax ary(i, j) // means ary[i][j]. This has the advantages of being simple and beautiful, and at the same time, using expressions in place of the indices is also simpler and less confusing.

To access, say, ary[2+5][3+8], you can write ary(2+5, 3+8) instead of the complex-looking ary[(2+5)*SizeY + (3+8)] i.e. it saves parentheses and helps readability.

Caveats:

• Although the syntax is very similar, it is NOT the same.
• In case you pass the array to other functions, SizeY has to be passed with the same name (or instead be declared as a global variable).

Or, if you need to use the array in multiple functions, then you could add SizeY also as another parameter in the macro definition like so:

#define ary(i, j, SizeY)  ary[(i)*(SizeY)+(j)]

You get the idea. Of course, this becomes too long to be useful, but it can still prevent the confusion of + and *.

This is not recommended definitely, and it will be condemned as bad practice by most experienced users, but I couldn't resist sharing it because of its elegance.

Edit:
If you want a portable solution that works for any number of arrays, you can use this syntax:

#define access(ar, i, j, SizeY) ar[(i)*(SizeY)+(j)]

and then you can pass on any array to the call, with any size using the access syntax:

access(ary, i, j, SizeY)      // ary[i][j]

P.S.: I've tested these, and the same syntax works (as both an lvalue and an rvalue) on g++14 and g++11 compilers.

This may also tangentially help, to understand if a logging request (from the code) at a certain level will result in it actually being logged given the effective logging level that a deployment is configured with. Decide what effective level you want to configure you deployment with from the other Answers here, and then refer to this to see if a particular logging request from your code will actually be logged then...

For examples:

• "Will a logging code line that logs at WARN actually get logged on my deployment configured with ERROR?" The table says, NO.
• "Will a logging code line that logs at WARN actually get logged on my deployment configured with DEBUG?" The table says, YES.

from logback documentation:

In a more graphic way, here is how the selection rule works. In the following table, the vertical header shows the level of the logging request, designated by p, while the horizontal header shows effective level of the logger, designated by q. The intersection of the rows (level request) and columns (effective level) is the boolean resulting from the basic selection rule.

So a code line that requests logging will only actually get logged if the effective logging level of its deployment is less than or equal to that code line's requested level of severity.

For me the issue turned out to be I was using es6's right arrow functions => as opposed to function ().

Replacing => with function () resolved for me.

I had assumed it was a jQuery issue.

Like this:

    std::string s("Test string");
    std::string::iterator it = s.begin();

    //Use the iterator...
    ++it;
    //...

    std::cout << "index is: " << std::distance(s.begin(), it) << std::endl;

Exactly what you need:) You can choose callback version or Promise version. Note that promises will work in IE only with Promise polyfill lib.You can put this code once on a page, and this function will appear in all your files.

The loadend event is fired when progress has stopped on the loading of a resource (e.g. after "error", "abort", or "load" have been dispatched)

Callback version

        File.prototype.convertToBase64 = function(callback){
                var reader = new FileReader();
                reader.onloadend = function (e) {
                    callback(e.target.result, e.target.error);
                };   
                reader.readAsDataURL(this);
        };

        $("#asd").on('change',function(){
          var selectedFile = this.files[0];
          selectedFile.convertToBase64(function(base64){
               alert(base64);
          }) 
        });

Promise version

    File.prototype.convertToBase64 = function(){
         return new Promise(function(resolve, reject) {
                var reader = new FileReader();
                reader.onloadend = function (e) {
                    resolve({
                      fileName: this.name,
                      result: e.target.result, 
                      error: e.target.error
                    });
                };   
                reader.readAsDataURL(this);
        }.bind(this)); 
    };

    FileList.prototype.convertAllToBase64 = function(regexp){
      // empty regexp if not set
      regexp = regexp || /.*/;
      //making array from FileList
      var filesArray = Array.prototype.slice.call(this);
      var base64PromisesArray = filesArray.
           filter(function(file){
             return (regexp).test(file.name)
           }).map(function(file){
             return file.convertToBase64();
           });
      return Promise.all(base64PromisesArray);
    };

    $("#asd").on('change',function(){
      //for one file
      var selectedFile = this.files[0];
      selectedFile.convertToBase64().
          then(function(obj){
            alert(obj.result);
          });
      });
      //for all files that have file extention png, jpeg, jpg, gif
      this.files.convertAllToBase64(/\.(png|jpeg|jpg|gif)$/i).then(function(objArray){
            objArray.forEach(function(obj, i){
                  console.log("result[" + obj.fileName + "][" + i + "] = " + obj.result);
            });
      });
    })

html

<input type="file" id="asd" multiple/>

Update:

if (localStorage.hasOwnProperty("username")) {
    //
}

Another way, relevant when value is not expected to be empty string, null or any other falsy value:

if (localStorage["username"]) {
    //
}

You can use YQL to do the request without needing to host your own proxy. I have made a simple function to make it easier to run commands:

function RunYQL(command, callback){
     callback_name = "__YQL_callback_"+(new Date()).getTime();
     window[callback_name] = callback;
     a = document.createElement('script');
     a.src = "http://query.yahooapis.com/v1/public/yql?q="
             +escape(command)+"&format=json&callback="+callback_name;
     a.type = "text/javascript";
     document.getElementsByTagName("head")[0].appendChild(a);
}

If you have jQuery, you may use $.getJSON instead.

A sample may be this:

RunYQL('select * from html where url="http://www.google.com/"',
       function(data){/* actions */}
);

Just had this happen to me.

Apparently Java's automatic updater installed and configured a new version of the JRE for me, while leaving the old JDK intact. So even though I did have a JDK, it didn't match the currently "active" JRE, which was causing the error.

Download a matching version of the JDK to the JRE you currently have installed, (In OP's case 151) That should do the trick.
