Programs & Examples On #Sql server agent

As Marc says, you run it exactly like you would from the command line. See Creating SQL Server Agent Jobs on MSDN.

Just solved this problem. In my case it was domain controller is not accessible, because both dns servers was google dns.

I just add to checklist for this problem:

• check domain controller is accessible

I dont know if you solved this issue, but i had same issue, if the instance is local you must check the permission to access the file, but if you are accessing from your computer to a server (remote access) you have to specify the path in the server, so that means to include the file in a server directory, that solved my case

example:

BULK INSERT Table
FROM 'C:\bulk\usuarios_prueba.csv' -- This is server path not local
WITH 
  (
     FIELDTERMINATOR =',',
     ROWTERMINATOR ='\n'
  );

Sure you can.

ALTER TABLE myTable ALTER COLUMN myColumn int NULL

Just substitute int for whatever datatype your column is.

$name = str_replace(' ', '_', $name);

To accessing member functions or variables from one scope to another scope (In your case one method to another method we need to refer method or variable with class object. and you can do it by referring with self keyword which refer as class object.

class YourClass():

    def your_function(self, *args):

        self.callable_function(param) # if you need to pass any parameter

    def callable_function(self, *params): 
        print('Your param:', param)

we can set the range of textfield like this..

-(BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range  replacementString:(NSString *)string
{
     int setrange = 20;
     return !([textField.text length]>setrange && [string length] > range.length);
}

You didn't select post_id in the subquery. You have to select it in the subquery like this:

SELECT wp_woocommerce_order_items.order_id As No_Commande
FROM  wp_woocommerce_order_items
LEFT JOIN 
    (
        SELECT meta_value As Prenom, post_id  -- <----- this
        FROM wp_postmeta
        WHERE meta_key = '_shipping_first_name'
    ) AS a
ON wp_woocommerce_order_items.order_id = a.post_id
WHERE  wp_woocommerce_order_items.order_id =2198 

To answer the original question:

HTMLDocument doc = new HTMLDocument();
IHTMLDocument2 doc2 = (IHTMLDocument2)doc;
doc2.write(fileText);
// now use doc

Then to convert back to a string:

doc.documentElement.outerHTML;

I used the above rule to fwd www to no www and it works fine for the homepage, however on the internal pages they are forwarding to /index.php

I found this other rule in my .htaccess file which is causing this but not sure what to do about it. Any suggestions would be great:

############################################
## always send 404 on missing files in these folders

    RewriteCond %{REQUEST_URI} !^/(media|skin|js)/

############################################
## never rewrite for existing files, directories and links

    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteCond %{REQUEST_FILENAME} !-l

############################################
## rewrite everything else to index.php

    RewriteRule .* index.php [L]

android:backgroundTintMode

Blending mode used to apply the background tint.

android:backgroundTint

Tint to apply to the background. Must be a color value, in the form of #rgb, #argb, #rrggbb, or #aarrggbb.

This may also be a reference to a resource (in the form "@[package:]type:name") or theme attribute (in the form "?[package:][type:]name") containing a value of this type.

ws2s project is aimed at bring socket to browser-side js. It is a websocket server which transform websocket to socket.

ws2s schematic diagram

code sample:

var socket = new WS2S("wss://ws2s.feling.io/").newSocket()

socket.onReady = () => {
  socket.connect("feling.io", 80)
  socket.send("GET / HTTP/1.1\r\nHost: feling.io\r\nConnection: close\r\n\r\n")
}

socket.onRecv = (data) => {
  console.log('onRecv', data)
}

I just simply place select statements in key areas of the stored procedure to check on current status of data sets, and then comment them out (--select...) or remove them before production.

array_splice — Remove a portion of the array and replace it with something else:

$input = array(1, 2, 3, 4, 5, 6);
array_splice($input, 5); // $input is now array(1, 2, 3, 4, 5)

From PHP manual:

array array_splice ( array &$input , int $offset [, int $length = 0 [, mixed $replacement]])

If length is omitted, removes everything from offset to the end of the array. If length is specified and is positive, then that many elements will be removed. If length is specified and is negative then the end of the removed portion will be that many elements from the end of the array. Tip: to remove everything from offset to the end of the array when replacement is also specified, use count($input) for length .

If you're using a Frame (Class Extends Frame) you'll not get the

frame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE)

In case of a number you can try to convert to string:

var stringValue = str.toString();
return stringValue.replace(/^\s+|\s+$/g,'');

This is a variation of the anwser by Muhammad Rehan Saeed, with the class getting parasitically attached to the existing .net core MVC class of the same name, so that everything just works.

js-xlsx library makes it easy to convert Excel/CSV files into JSON objects.

Download the xlsx.full.min.js file from here. Write below code on your HTML page Edit the referenced js file link (xlsx.full.min.js) and link of Excel file

<!doctype html>
<html>

        /* set up XMLHttpRequest */
        var url = "http://myclassbook.org/wp-content/uploads/2017/12/Test.xlsx";

In case anyone would be searching - I created utility for automated import of xlsx files into google spreadsheet: xls2sheets. One can do it automatically via setting up the cronjob for ./cmd/sheets-refresh, readme describes it all. Hope that would be of use.

The solutions here didn't work for me as I'm styling react components.

What worked though for the sidebar was

.sidebar{
position: sticky;
top: 0;
}

Hope this helps someone.

props.children represents the content between the opening and the closing tags when invoking/rendering a component:

const Foo = props => (
  <div>
    <p>I'm {Foo.name}</p>
    <p>abc is: {props.abc}</p>

    <p>I have {props.children.length} children.</p>
    <p>They are: {props.children}.</p>
    <p>{Array.isArray(props.children) ? 'My kids are an array.' : ''}</p>
  </div>
);

const Baz = () => <span>{Baz.name} and</span>;
const Bar = () => <span> {Bar.name}</span>;

invoke/call/render Foo:

<Foo abc={123}>
  <Baz />
  <Bar />
</Foo>

Try this

SELECT TOP 1 salary FROM (
   SELECT TOP 3 salary 
   FROM employees 
   ORDER BY salary DESC) AS emp 
ORDER BY salary ASC

For 3 you can replace any value...

You are not calling the function inner, just defining it.

function outer() { 
    function inner() {
        alert("hi");
    }

    inner(); //Call the inner function

}

On the contrary, I do think working with list makes it easy to automate such things.

Here is one solution (I stored your four dataframes in folder temp/).

filenames <- list.files("temp", pattern="*.csv", full.names=TRUE)
ldf <- lapply(filenames, read.csv)
res <- lapply(ldf, summary)
names(res) <- substr(filenames, 6, 30)

It is important to store the full path for your files (as I did with full.names), otherwise you have to paste the working directory, e.g.

filenames <- list.files("temp", pattern="*.csv")
paste("temp", filenames, sep="/")

will work too. Note that I used substr to extract file names while discarding full path.

You can access your summary tables as follows:

> res$`df4.csv`
       A              B        
 Min.   :0.00   Min.   : 1.00  
 1st Qu.:1.25   1st Qu.: 2.25  
 Median :3.00   Median : 6.00  
 Mean   :3.50   Mean   : 7.00  
 3rd Qu.:5.50   3rd Qu.:10.50  
 Max.   :8.00   Max.   :16.00  

If you really want to get individual summary tables, you can extract them afterwards. E.g.,

for (i in 1:length(res))
  assign(paste(paste("df", i, sep=""), "summary", sep="."), res[[i]])

This will be in synchronisation with an api call, When the api call is triggered, the loader is shown. When the api call is succesful, the loader is removed. This can be used for either page load or during an api call.

  $.ajax({
    type: 'GET',
    url: url,
    async: true,
    dataType: 'json',
    beforeSend: function (xhr) {
      $( "<div class='loader' id='searching-loader'></div>").appendTo("#table-playlist-section");
      $("html, body").animate( { scrollTop: $(document).height() }, 100);
    },
    success: function (jsonOptions) {
      $('#searching-loader').remove();
      .
      .
    }
  });

CSS

.loader {
  border: 2px solid #f3f3f3;
  border-radius: 50%;
  border-top: 2px solid #3498db;
  width: 30px;
  height: 30px;
  margin: auto;
  -webkit-animation: spin 2s linear infinite; /* Safari */
  animation: spin 2s linear infinite;
  margin-top: 35px;
  margin-bottom: -35px;
}

/* Safari */
@-webkit-keyframes spin {
  0% { -webkit-transform: rotate(0deg); }
  100% { -webkit-transform: rotate(360deg); }
}

@keyframes spin {
  0% { transform: rotate(0deg); }
  100% { transform: rotate(360deg); }
}

After @SedatKapanoglu comment, I am adding all my approach that works, because he was right, just using the fluent API does not work.

1- Create custom code generator and override Generate for a ColumnModel.

   public class ExtendedMigrationCodeGenerator : CSharpMigrationCodeGenerator
{

    protected override void Generate(ColumnModel column, IndentedTextWriter writer, bool emitName = false)
    {

        if (column.Annotations.Keys.Contains("Default"))
        {
            var value = Convert.ChangeType(column.Annotations["Default"].NewValue, column.ClrDefaultValue.GetType());
            column.DefaultValue = value;
        }


        base.Generate(column, writer, emitName);
    }

}

2- Assign the new code generator:

public sealed class Configuration : DbMigrationsConfiguration<Data.Context.EfSqlDbContext>
{
    public Configuration()
    {
        CodeGenerator = new ExtendedMigrationCodeGenerator();
        AutomaticMigrationsEnabled = false;
    }
}

3- Use fluent api to created the Annotation:

public static void Configure(DbModelBuilder builder){    
builder.Entity<Company>().Property(c => c.Status).HasColumnAnnotation("Default", 0);            
}

Another option that worked for me was to add onsubmit="return false;" to the form tag.

<form onsubmit="return false;">

Semantically probably not as good a solution as the above methods of changing the button type, but seems to be an option if you just want a form element the won't submit.

Okay, per http://www.oracle.com/technology/tech/globalization/htdocs/nls_lang%20faq.htm:

NLS_LANG cannot be changed by ALTER SESSION, NLS_LANGUAGE and NLS_TERRITORY can. However NLS_LANGUAGE and /or NLS_TERRITORY cannot be set as "standalone" parameters in the environment or registry on the client.

Evidently the "right" solution is, before logging into Oracle at all, setting the following environment variable:

export NLS_LANG=AMERICAN_AMERICA.UTF8

Oracle gets a big fat F for usability.

You could just use the FolderBrowserDialog class from the System.Windows.Forms namespace.

In your case (and in most use cases I have seen), all you need is:

$("#baba").val("");

Demo.

The most general difference between procedures and functions is that they are invoked differently and for different purposes:

1. A procedure does not return a value. Instead, it is invoked with a CALL statement to perform an operation such as modifying a table or processing retrieved records.
2. A function is invoked within an expression and returns a single value directly to the caller to be used in the expression.
3. You cannot invoke a function with a CALL statement, nor can you invoke a procedure in an expression.

Syntax for routine creation differs somewhat for procedures and functions:

1. Procedure parameters can be defined as input-only, output-only, or both. This means that a procedure can pass values back to the caller by using output parameters. These values can be accessed in statements that follow the CALL statement. Functions have only input parameters. As a result, although both procedures and functions can have parameters, procedure parameter declaration differs from that for functions.

2. Functions return value, so there must be a RETURNS clause in a function definition to indicate the data type of the return value. Also, there must be at least one RETURN statement within the function body to return a value to the caller. RETURNS and RETURN do not appear in procedure definitions.

   • To invoke a stored procedure, use the CALL statement. To invoke a stored function, refer to it in an expression. The function returns a value during expression evaluation.

   • A procedure is invoked using a CALL statement, and can only pass back values using output variables. A function can be called from inside a statement just like any other function (that is, by invoking the function's name), and can return a scalar value.

   • Specifying a parameter as IN, OUT, or INOUT is valid only for a PROCEDURE. For a FUNCTION, parameters are always regarded as IN parameters.

   If no keyword is given before a parameter name, it is an IN parameter by default. Parameters for stored functions are not preceded by IN, OUT, or INOUT. All function parameters are treated as IN parameters.

To define a stored procedure or function, use CREATE PROCEDURE or CREATE FUNCTION respectively:

CREATE PROCEDURE proc_name ([parameters])
 [characteristics]
 routine_body


CREATE FUNCTION func_name ([parameters])
 RETURNS data_type       // diffrent
 [characteristics]
 routine_body

A MySQL extension for stored procedure (not functions) is that a procedure can generate a result set, or even multiple result sets, which the caller processes the same way as the result of a SELECT statement. However, the contents of such result sets cannot be used directly in expression.

Stored routines (referring to both stored procedures and stored functions) are associated with a particular database, just like tables or views. When you drop a database, any stored routines in the database are also dropped.

Stored procedures and functions do not share the same namespace. It is possible to have a procedure and a function with the same name in a database.

In Stored procedures dynamic SQL can be used but not in functions or triggers.

SQL prepared statements (PREPARE, EXECUTE, DEALLOCATE PREPARE) can be used in stored procedures, but not stored functions or triggers. Thus, stored functions and triggers cannot use Dynamic SQL (where you construct statements as strings and then execute them). (Dynamic SQL in MySQL stored routines)

Some more interesting differences between FUNCTION and STORED PROCEDURE:

1. (This point is copied from a blogpost.) Stored procedure is precompiled execution plan where as functions are not. Function Parsed and compiled at runtime. Stored procedures, Stored as a pseudo-code in database i.e. compiled form.

2. (I'm not sure for this point.)
   Stored procedure has the security and reduces the network traffic and also we can call stored procedure in any no. of applications at a time. reference

3. Functions are normally used for computations where as procedures are normally used for executing business logic.

4. Functions Cannot affect the state of database (Statements that do explicit or implicit commit or rollback are disallowed in function) Whereas Stored procedures Can affect the state of database using commit etc.
   refrence: J.1. Restrictions on Stored Routines and Triggers

5. Functions can't use FLUSH statements whereas Stored procedures can do.

6. Stored functions cannot be recursive Whereas Stored procedures can be. Note: Recursive stored procedures are disabled by default, but can be enabled on the server by setting the max_sp_recursion_depth server system variable to a nonzero value. See Section 5.2.3, “System Variables”, for more information.

7. Within a stored function or trigger, it is not permitted to modify a table that is already being used (for reading or writing) by the statement that invoked the function or trigger. Good Example: How to Update same table on deletion in MYSQL?

Note: that although some restrictions normally apply to stored functions and triggers but not to stored procedures, those restrictions do apply to stored procedures if they are invoked from within a stored function or trigger. For example, although you can use FLUSH in a stored procedure, such a stored procedure cannot be called from a stored function or trigger.

In my case, the database was related to an old Sharepoint install. Stopping and disabling related services in the server manager "unhung" the take offline action, which had been running for 40 minutes, and it completed immediately.

You may wish to check if any services are currently utilizing the database.

Install HookyQR.beautify extension. It will beautify your javascript, JSON, CSS, Sass, and HTML in Visual Studio Code. It is the most use extensions for this purpose

Try this:

[Authorize]
public ActionResult SomeAction()
{
    var identity = (ClaimsIdentity)User.Identity;
    IEnumerable<Claim> claims = identity.Claims;
    ...
}

Something like this:

public static String innerSubString(String txt, char prefix, char suffix) {

    if(txt != null && txt.length() > 1) {

        int start = 0, end = 0;
        char token;
        for(int i = 0; i < txt.length(); i++) {
            token = txt.charAt(i);
            if(token == prefix)
                start = i;
            else if(token == suffix)
                end = i;
        }

        if(start + 1 < end)
            return txt.substring(start+1, end);

    }

    return null;
}

I have created the Fade in and Fade Out animation for Dialogbox using ChrisJD code.

1. Inside res/style.xml

If anyone came to this question looking for ways to add multiple parameters at the same time (my case), you can use .params with a MultivalueMap instead of adding each .param :

LinkedMultiValueMap<String, String> requestParams = new LinkedMultiValueMap<>()
requestParams.add("id", "1");
requestParams.add("name", "john");
requestParams.add("age", "30");

mockMvc.perform(get("my/endpoint").params(requestParams)).andExpect(status().isOk())

In my case, I had a nested list as the series that I wanted to use as an input.

First check: If

df['nestedList'][0]

outputs a list like [1,2,3], you have a nested list.

Then check if you still get the error when changing to input df['nestedList'][0].

Then your next step is probably to concatenate all nested lists into one unnested list, using

[item for sublist in df['nestedList'] for item in sublist]

This flattening of the nested list is borrowed from How to make a flat list out of list of lists?.

How about with a :before pseudoelement:

a:before {
  content: '\a';
  white-space: pre;
}

Having tested this using Python 3.5 and pip 7.1.2 on Linux, the situation appears to be this:

• pip install --user somepackage installs to $HOME/.local, and uninstalling it does work using pip uninstall somepackage.

• This is true whether or not somepackage is also installed system-wide at the same time.

• If the package is installed at both places, only the local one will be uninstalled. To uninstall the package system-wide using pip, first uninstall it locally, then run the same uninstall command again, with root privileges.

• In addition to the predefined user install directory, pip install --target somedir somepackage will install the package into somedir. There is no way to uninstall a package from such a place using pip. (But there is a somewhat old unmerged pull request on Github that implements pip uninstall --target.)

• Since the only places pip will ever uninstall from are system-wide and predefined user-local, you need to run pip uninstall as the respective user to uninstall from a given user's local install directory.

How to specify 64 bit integers in c

Going against the usual good idea to appending LL.

Appending LL to a integer constant will insure the type is at least as wide as long long. If the integer constant is octal or hex, the constant will become unsigned long long if needed.

If ones does not care to specify too wide a type, then LL is OK. else, read on.

long long may be wider than 64-bit.

Today, it is rare that long long is not 64-bit, yet C specifies long long to be at least 64-bit. So by using LL, in the future, code may be specifying, say, a 128-bit number.

C has Macros for integer constants which in the below case will be type int_least64_t

#include <stdint.h>
#include <inttypes.h>

int main(void) {
  int64_t big = INT64_C(9223372036854775807);
  printf("%" PRId64 "\n", big);
  uint64_t jenny = INT64_C(0x08675309) << 32;  // shift was done on at least 64-bit type 
  printf("0x%" PRIX64 "\n", jenny);
}

output

9223372036854775807
0x867530900000000

get python path from

ls /usr/bin/python*

then set your python version

alias python="/usr/bin/python3"

For anyone looking for an Angular2 (2.4.8) solution, since this is a generically-popular question when searching:

<div *ngFor="let choice of choices">
  <input type="radio" [checked]="choice == defaultChoice">
</div>

This will add the checked attribute to the input given the condition, but will add nothing if the condition fails.

Do not do this:

[attr.checked]="choice == defaultChoice"

because this will add the attribute checked="false" to every other input element.

Since the browser only looks for the presence of the checked attribute (the key), ignoring its value, so the last input in the group will be checked.

All of above do not work for me.

What I found was click the Details button.

Then it works.

Your regex should be something like

[0-9\-\(\)\s]+.

It matches numbers, dashes, parentheses and space.

If you need something more strict, matching just your example, try this:

([0-9]{10})|(\([0-9]{3}\)\s+[0-9]{3}\-[0-9]{4})

from operator import truediv

c = truediv(a, b)

where a is dividend and b is the divisor. This function is handy when quotient after division of two integers is a float.

Just spotted this thread while searching for this very answer. I just made a small jQuery function, hope this helps, works like a charm:

JAVASCRIPT

var maxHeight = 0;
$('.inner').each(function() {
    maxHeight = Math.max(maxHeight, $(this).height());
});
$('.lhs_content .inner, .rhs_content .inner').css({height:maxHeight + 'px'});

HTML

<div class="lhs_content">
    <div class="inner">
        Content in here
    </div>
</div>
<div class="rhs_content">
    <div class="inner">
        More content in here
    </div>
</div>

Just ran into this again (certain I had before and came up with a less-than-satisfying solution).

For a tri-state boolean semantic (for example, using models.NullBooleanField), this works well:

{% if test.passed|lower == 'false' %} ... {% endif %}

Or if you prefer getting excited over the whole thing...

{% if test.passed|upper == 'FALSE' %} ... {% endif %}

Either way, this handles the special condition where you don't care about the None (evaluating to False in the if block) or True case.

As explained in "Deleting your master branch" by Matthew Brett, you need to change your GitHub repo default branch.

You need to go to the GitHub page for your forked repository, and click on the “Settings” button.

Click on the "Branches" tab on the left hand side. There’s a “Default branch” dropdown list near the top of the screen.

From there, select placeholder (where placeholder is the dummy name for your new default branch).

Confirm that you want to change your default branch.

Now you can do (from the command line):

git push origin :master

Or, since 2012, you can delete that same branch directly on GitHub:

That was announced in Sept. 2013, a year after I initially wrote that answer.

For small changes like documentation fixes, typos, or if you’re just a walking software compiler, you can get a lot done in your browser without needing to clone the entire repository to your computer.

Note: for BitBucket, Tum reports in the comments:

size_t is the size of a pointer.

So in 32 bits or the common ILP32 (integer, long, pointer) model size_t is 32 bits. and in 64 bits or the common LP64 (long, pointer) model size_t is 64 bits (integers are still 32 bits).

There are other models but these are the ones that g++ use (at least by default)

Java have a String pool under which Java manages the memory allocation for the String objects. See String Pools in Java

When you check (compare) two objects using the == operator it compares the address equality into the string-pool. If the two String objects have the same address references then it returns true, otherwise false. But if you want to compare the contents of two String objects then you must override the equals method.

equals is actually the method of the Object class, but it is Overridden into the String class and a new definition is given which compares the contents of object.

Example:
    stringObjectOne.equals(stringObjectTwo);

But mind it respects the case of String. If you want case insensitive compare then you must go for the equalsIgnoreCase method of the String class.

Let's See:

String one   = "HELLO"; 
String two   = "HELLO"; 
String three = new String("HELLO"); 
String four  = "hello"; 

one == two;   // TRUE
one == three; // FALSE
one == four;  // FALSE

one.equals(two);            // TRUE
one.equals(three);          // TRUE
one.equals(four);           // FALSE
one.equalsIgnoreCase(four); // TRUE

A more elegant way I found to achieve this behaviour is simply:

<div id="{{ 'object-' + myScopeObject.index }}"></div>

For my implementation I wanted each input element in a ng-repeat to each have a unique id to associate the label with. So for an array of objects contained inside myScopeObjects one could do this:

<div ng-repeat="object in myScopeObject">
    <input id="{{object.name + 'Checkbox'}}" type="checkbox">
    <label for="{{object.name + 'Checkbox'}}">{{object.name}}</label>
</div>

Being able to generate unique ids on the fly can be pretty useful when dynamically adding content like this.

df.groupby('l_customer_id_i').agg(lambda x: ','.join(x)) does already return a dataframe, so you cannot loop over the groups anymore.

In general:

• df.groupby(...) returns a GroupBy object (a DataFrameGroupBy or SeriesGroupBy), and with this, you can iterate through the groups (as explained in the docs here). You can do something like:

  grouped = df.groupby('A')
  
  for name, group in grouped:
      ...
  

• When you apply a function on the groupby, in your example df.groupby(...).agg(...) (but this can also be transform, apply, mean, ...), you combine the result of applying the function to the different groups together in one dataframe (the apply and combine step of the 'split-apply-combine' paradigm of groupby). So the result of this will always be again a DataFrame (or a Series depending on the applied function).

SignalR provides ConnectionId for each connection. To find which connection belongs to whom (the user), we need to create a mapping between the connection and the user. This depends on how you identify a user in your application.

In SignalR 2.0, this is done by using the inbuilt IPrincipal.Identity.Name, which is the logged in user identifier as set during the ASP.NET authentication.

However, you may need to map the connection with the user using a different identifier instead of using the Identity.Name. For this purpose this new provider can be used with your custom implementation for mapping user with the connection.

Example of Mapping SignalR Users to Connections using IUserIdProvider

Lets assume our application uses a userId to identify each user. Now, we need to send message to a specific user. We have userId and message, but SignalR must also know the mapping between our userId and the connection.

To achieve this, first we need to create a new class which implements IUserIdProvider:

public class CustomUserIdProvider : IUserIdProvider
{
     public string GetUserId(IRequest request)
    {
        // your logic to fetch a user identifier goes here.

        // for example:

        var userId = MyCustomUserClass.FindUserId(request.User.Identity.Name);
        return userId.ToString();
    }
}

The second step is to tell SignalR to use our CustomUserIdProvider instead of the default implementation. This can be done in the Startup.cs while initializing the hub configuration:

public class Startup
{
    public void Configuration(IAppBuilder app)
    {
        var idProvider = new CustomUserIdProvider();

        GlobalHost.DependencyResolver.Register(typeof(IUserIdProvider), () => idProvider);          

        // Any connection or hub wire up and configuration should go here
        app.MapSignalR();
    }
}

Now, you can send message to a specific user using his userId as mentioned in the documentation, like:

public class MyHub : Hub
{
   public void Send(string userId, string message)
   {
      Clients.User(userId).send(message);
   }
}

Hope this helps.

In addition to selecting all elements with an attribute $('[someAttribute]') or $('input[someAttribute]') you can also use a function for doing boolean checks on an object such as in a click handler:

if(! this.hasAttribute('myattr') ) { ...

cd /the/lib/dir/of/your/perl/installation
perldoc $(find . -name perllocal.pod)

Windows users just do a Windows Explorer search to find it.

First you need to remember that in Unix and Linux, everything is a file, even directories. For a file to have the rights to be executed as a command, it needs to satisfy 3 conditions:

1. It needs to be a regular file
2. It needs to have read-permissions
3. It needs to have execute-permissions

So this can be done simply with:

[ -f "${file}" ] && [ -r "${file}" ] && [ -x "${file}" ]

If your file is a symbolic link to a regular file, the test command will operate on the target and not the link-name. So the above command distinguishes if a file can be used as a command or not. So there is no need to pass the file first to realpath or readlink or any of those variants.

If the file can be executed on the current OS, that is a different question. Some answers above already pointed to some possibilities for that, so there is no need to repeat it here.

This worked for me. Thank you Rody!

y="HELLO"
val=$(echo $y | tr '[:upper:]' '[:lower:]')
string="$val world"

one small modification, if you are using underscore next to the variable You need to encapsulate the variable name in {}.

string="${val}_world"

The classes which you are importing have to be on the classpath. So either the users of your Applet have to have the libraries in the right place or you simply provide those libraries by including them in your jar file. For example like this: Easiest way to merge a release into one JAR file

str_replace('"', "", $string);
str_replace("'", "", $string);

I assume you mean quotation marks?

Otherwise, go for some regex, this will work for html quotes for example:

preg_replace("/<!--.*?-->/", "", $string);

C-style quotes:

preg_replace("/\/\/.*?\n/", "\n", $string);

CSS-style quotes:

preg_replace("/\/*.*?\*\//", "", $string);

bash-style quotes:

preg-replace("/#.*?\n/", "\n", $string);

Etc etc...

i had to use it for a condition add if you don't need the index

using System.Linq;

use

if(list.Any(x => x.Title == title){
// do something here
}

this will tell you if any variable satisfies your given condition.

Javascript being dynamic language there a zillion ways to mess up where another language would stop you.

Avoiding a fundamental language feature such as new on the basis that you might mess up is a bit like removing your shiny new shoes before walking through a minefield just in case you might get your shoes muddy.

I use a convention where function names begin with a lower case letter and 'functions' that are actually class definitions begin with a upper case letter. The result is a really quite compelling visual clue that the 'syntax' is wrong:-

var o = MyClass();  // this is clearly wrong.

On top of this good naming habits help. After all functions do things and therefore there should be a verb in its name whereas classes represent objects and are nouns and adjectives with no verb.

var o = chair() // Executing chair is daft.
var o = createChair() // makes sense.

Its interesting how SO's syntax colouring has interpretted the code above.

Here is a revision of @Tayrn answer above that might help you understand pivoting a little easier:

This may not be the best way to do this, but this is what helped me wrap my head around how to pivot tables.

ID = rows you want to pivot

MY_KEY = the column you are selecting from your original table that contains the column names you want to pivot.

VAL = the value you want returning under each column.

MAX(VAL) => Can be replaced with other aggregiate functions. SUM(VAL), MIN(VAL), ETC...

DECLARE @cols AS NVARCHAR(MAX),
@query  AS NVARCHAR(MAX)
select @cols = STUFF((SELECT ',' + QUOTENAME(MY_KEY) 
                from yt
                group by MY_KEY
                order by MY_KEY ASC
        FOR XML PATH(''), TYPE
        ).value('.', 'NVARCHAR(MAX)') 
    ,1,1,'')
set @query = 'SELECT ID,' + @cols + ' from 
         (
            select ID, MY_KEY, VAL 
            from yt
        ) x
        pivot 
        (
            sum(VAL)
            for MY_KEY in (' + @cols + ')
        ) p '

        execute(@query);

Nope, it is more complicated than just calling a method, if you want to transparently add it into the user's calendar.

You've got a couple of choices;

1. Calling the intent to add an event on the calendar
   This will pop up the Calendar application and let the user add the event. You can pass some parameters to prepopulate fields:

   Calendar cal = Calendar.getInstance();              
   Intent intent = new Intent(Intent.ACTION_EDIT);
   intent.setType("vnd.android.cursor.item/event");
   intent.putExtra("beginTime", cal.getTimeInMillis());
   intent.putExtra("allDay", false);
   intent.putExtra("rrule", "FREQ=DAILY");
   intent.putExtra("endTime", cal.getTimeInMillis()+60*60*1000);
   intent.putExtra("title", "A Test Event from android app");
   startActivity(intent);
   

   Or the more complicated one:

2. Get a reference to the calendar with this method
   (It is highly recommended not to use this method, because it could break on newer Android versions):

   private String getCalendarUriBase(Activity act) {
   
       String calendarUriBase = null;
       Uri calendars = Uri.parse("content://calendar/calendars");
       Cursor managedCursor = null;
       try {
           managedCursor = act.managedQuery(calendars, null, null, null, null);
       } catch (Exception e) {
       }
       if (managedCursor != null) {
           calendarUriBase = "content://calendar/";
       } else {
           calendars = Uri.parse("content://com.android.calendar/calendars");
           try {
               managedCursor = act.managedQuery(calendars, null, null, null, null);
           } catch (Exception e) {
           }
           if (managedCursor != null) {
               calendarUriBase = "content://com.android.calendar/";
           }
       }
       return calendarUriBase;
   }
   

   and add an event and a reminder this way:

   // get calendar
   Calendar cal = Calendar.getInstance();     
   Uri EVENTS_URI = Uri.parse(getCalendarUriBase(this) + "events");
   ContentResolver cr = getContentResolver();
   
   // event insert
   ContentValues values = new ContentValues();
   values.put("calendar_id", 1);
   values.put("title", "Reminder Title");
   values.put("allDay", 0);
   values.put("dtstart", cal.getTimeInMillis() + 11*60*1000); // event starts at 11 minutes from now
   values.put("dtend", cal.getTimeInMillis()+60*60*1000); // ends 60 minutes from now
   values.put("description", "Reminder description");
   values.put("visibility", 0);
   values.put("hasAlarm", 1);
   Uri event = cr.insert(EVENTS_URI, values);
   
   // reminder insert
   Uri REMINDERS_URI = Uri.parse(getCalendarUriBase(this) + "reminders");
   values = new ContentValues();
   values.put( "event_id", Long.parseLong(event.getLastPathSegment()));
   values.put( "method", 1 );
   values.put( "minutes", 10 );
   cr.insert( REMINDERS_URI, values );
   

   You'll also need to add these permissions to your manifest for this method:

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

Update: ICS Issues

The above examples use the undocumented Calendar APIs, new public Calendar APIs have been released for ICS, so for this reason, to target new android versions you should use CalendarContract.

More infos about this can be found at this blog post.

CONIO.H

the functions you need are:

int getch();
Prototype
    int _getch(void); 
Description
    _getch obtains a character  from stdin. Input is unbuffered, and this
    routine  will  return as  soon as  a character is  available  without 
    waiting for a carriage return. The character is not echoed to stdout.
    _getch bypasses the normal buffering done by getchar and getc. ungetc 
    cannot be used with _getch. 
Synonym
    Function: getch 


int kbhit();
Description
    Checks if a keyboard key has been pressed but not yet read. 
Return Value
    Returns a non-zero value if a key was pressed. Otherwise, returns 0.

or

Linux c++ implementation of conio.h http://sourceforge.net/projects/linux-conioh

myObj.name=value

or

myObj['name']=value     (Quotes are required)

Both of these are interchangeable.

Edit: I'm guessing you meant myObj[prop] = value, instead of myObj[name] = value. Second syntax works fine: http://jsfiddle.net/waitinforatrain/dNjvb/1/

    print u

on shell works , sending to sdtout not , so that is one workaround, to write to stdout .

I made other approach, which is not run if sys.stdout.encoding is not define, or in others words , need export PYTHONIOENCODING=UTF-8 first to write to stdout.

import sys
if (sys.stdout.encoding is None):            
    print >> sys.stderr, "please set python env PYTHONIOENCODING=UTF-8, example: export PYTHONIOENCODING=UTF-8, when write to stdout." 
    exit(1)

so, using same example:

export PYTHONIOENCODING=UTF-8
./test.py > output.txt

will work

For Spark 2.0.2 with grouping by multiple columns:

import org.apache.spark.sql.functions.row_number
import org.apache.spark.sql.expressions.Window

val w = Window.partitionBy($"col1", $"col2", $"col3").orderBy($"timestamp".desc)

val refined_df = df.withColumn("rn", row_number.over(w)).where($"rn" === 1).drop("rn")

Floating point calculations are not exact - there is often round-off errors, and errors due to representation. (For example, 0.1 cannot be exactly represented in binary floating point.)

Because of this, directly comparing two floating point values for equality is usually not a good idea, because they can be different by a small amount, depending upon how they were computed.

The "delta", as it's called in the JUnit javadocs, describes the amount of difference you can tolerate in the values for them to be still considered equal. The size of this value is entirely dependent upon the values you're comparing. When comparing doubles, I typically use the expected value divided by 10^6.

for 1D and 2D arrays you can use np.savetxt to print using a specific format string:

>>> import sys
>>> x = numpy.arange(20).reshape((4,5))
>>> numpy.savetxt(sys.stdout, x, '%5.2f')
 0.00  1.00  2.00  3.00  4.00
 5.00  6.00  7.00  8.00  9.00
10.00 11.00 12.00 13.00 14.00
15.00 16.00 17.00 18.00 19.00

Your options with numpy.set_printoptions or numpy.array2string in v1.3 are pretty clunky and limited (for example no way to suppress scientific notation for large numbers). It looks like this will change with future versions, with numpy.set_printoptions(formatter=..) and numpy.array2string(style=..).

Solution with TC - O(n) and SC - O(1)

        if (str.charAt(i) == ' ' || i == str.length() - 1) {

            int end = 0;

            if (i == str.length() - 1) {
                end = i;
            } else {
                end = i - 1;
            }

            str = swap(str, start, end);
            start = i + 1;
        }
    }
    System.out.println(str);

 private static String swap(String str, int start, int end) {

    StringBuilder sb = new StringBuilder(str);

    while (start < end) {
        sb.setCharAt(start, str.charAt(end));
        sb.setCharAt(end, str.charAt(start));

    }
    return sb.toString();
}

You should use the OO interface to matplotlib, rather than the state machine interface. Almost all of the plt.* function are thin wrappers that basically do gca().*.

plt.subplot returns an axes object. Once you have a reference to the axes object you can plot directly to it, change its limits, etc.

import matplotlib.pyplot as plt

ax1 = plt.subplot(131)
ax1.scatter([1, 2], [3, 4])
ax1.set_xlim([0, 5])
ax1.set_ylim([0, 5])


ax2 = plt.subplot(132)
ax2.scatter([1, 2],[3, 4])
ax2.set_xlim([0, 5])
ax2.set_ylim([0, 5])

and so on for as many axes as you want.

or better, wrap it all up in a loop:

import matplotlib.pyplot as plt

DATA_x = ([1, 2],
          [2, 3],
          [3, 4])

DATA_y = DATA_x[::-1]

XLIMS = [[0, 10]] * 3
YLIMS = [[0, 10]] * 3

for j, (x, y, xlim, ylim) in enumerate(zip(DATA_x, DATA_y, XLIMS, YLIMS)):
    ax = plt.subplot(1, 3, j + 1)
    ax.scatter(x, y)
    ax.set_xlim(xlim)
    ax.set_ylim(ylim)

python setup.py uses distutils which doesn't support install_requires. setuptools does, also distribute (its successor), and pip (which uses either) do. But you actually have to use them. I.e. call setuptools through the easy_install command or pip install.

Another way is to import setup from setuptools in your setup.py, but this not standard and makes everybody wanting to use your package have to have setuptools installed.

I received the same message. My fix included: I deleted all the additional sheets (tabs) in the .csv file, eliminated non-numeric characters, resaved the file as comma delimited and loaded in R v 2.15.0 using standard language:

filename<-read.csv("filename",header=TRUE)

As an additional safeguard, I closed the software and reopened before I loaded the csv.

Very similar to Marc, only difference I would make would be to spool to a parameter like so:

WHENEVER SQLERROR EXIT 1
SET LINES 32000
SET TERMOUT OFF ECHO OFF NEWP 0 SPA 0 PAGES 0 FEED OFF HEAD OFF TRIMS ON TAB OFF
SET SERVEROUTPUT ON

spool &1

-- Code

spool off
exit

And then to call the SQLPLUS as

sqlplus -s username/password@sid @tmp.sql /tmp/output.txt

Did you tried JQuery's scrollTo method? http://demos.flesler.com/jquery/scrollTo/

Or you can extend JQuery and add your custom mentod:

jQuery.fn.extend({
 scrollToMe: function () {
   var x = jQuery(this).offset().top - 100;
   jQuery('html,body').animate({scrollTop: x}, 400);
}});

Then you can call this method like:

$("#header").scrollToMe();

Your best bet may be to create a function that sets styles on your own:

var setStyle = function(p_elem, p_styles)
{
    var s;
    for (s in p_styles)
    {
        p_elem.style[s] = p_styles[s];
    }
}

setStyle(myDiv, {'color': '#F00', 'backgroundColor': '#000'});
setStyle(myDiv, {'color': mycolorvar, 'backgroundColor': mybgvar});

Note that you will still have to use the javascript-compatible property names (hence backgroundColor)

You can use LENGTH() for CHAR / VARCHAR2 and DBMS_LOB.GETLENGTH() for CLOB. Both functions will count actual characters (not bytes).

See the linked documentation if you do need bytes.

With Java 8 in picture, jcmd is the preferred approach.

jcmd <PID> Thread.print

Following is the snippet from Oracle documentation :

The release of JDK 8 introduced Java Mission Control, Java Flight Recorder, and jcmd utility for diagnosing problems with JVM and Java applications. It is suggested to use the latest utility, jcmd instead of the previous jstack utility for enhanced diagnostics and reduced performance overhead.

However, shipping this with the application may be licensing implications which I am not sure.

[Ljava.lang.Object; is the name for Object[].class, the java.lang.Class representing the class of array of Object.

The naming scheme is documented in Class.getName():

If this class object represents a reference type that is not an array type then the binary name of the class is returned, as specified by the Java Language Specification (§13.1).

If this class object represents a primitive type or void, then the name returned is the Java language keyword corresponding to the primitive type or void.

If this class object represents a class of arrays, then the internal form of the name consists of the name of the element type preceded by one or more '[' characters representing the depth of the array nesting. The encoding of element type names is as follows:

Element Type        Encoding
boolean             Z
byte                B
char                C

Yours is the last on that list. Here are some examples:

// xxxxx varies
System.out.println(new int[0][0][7]); // [[[I@xxxxx
System.out.println(new String[4][2]); // [[Ljava.lang.String;@xxxxx
System.out.println(new boolean[256]); // [Z@xxxxx

The reason why the toString() method on arrays returns String in this format is because arrays do not @Override the method inherited from Object, which is specified as follows:

The toString method for class Object returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of:

getClass().getName() + '@' + Integer.toHexString(hashCode())

Note: you can not rely on the toString() of any arbitrary object to follow the above specification, since they can (and usually do) @Override it to return something else. The more reliable way of inspecting the type of an arbitrary object is to invoke getClass() on it (a final method inherited from Object) and then reflecting on the returned Class object. Ideally, though, the API should've been designed such that reflection is not necessary (see Effective Java 2nd Edition, Item 53: Prefer interfaces to reflection).

On a more "useful" toString for arrays

java.util.Arrays provides toString overloads for primitive arrays and Object[]. There is also deepToString that you may want to use for nested arrays.

Here are some examples:

int[] nums = { 1, 2, 3 };

System.out.println(nums);
// [I@xxxxx

System.out.println(Arrays.toString(nums));
// [1, 2, 3]

int[][] table = {
        { 1, },
        { 2, 3, },
        { 4, 5, 6, },
};

System.out.println(Arrays.toString(table));
// [[I@xxxxx, [I@yyyyy, [I@zzzzz]

System.out.println(Arrays.deepToString(table));
// [[1], [2, 3], [4, 5, 6]]

There are also Arrays.equals and Arrays.deepEquals that perform array equality comparison by their elements, among many other array-related utility methods.

UIColor's RGB components are scaled between 0 and 1, not up to 255.

Try

categoryTitle.textColor = [UIColor colorWithRed:(188/255.f) green:... blue:... alpha:1.0];

In Swift:

categoryTitle.textColor = UIColor(red: 188/255.0, green: ..., blue: ..., alpha: 1)

it looks like this is the way to do! as simple as that

with this line you are joining together the all text parts within the current element

''.join(htmlelement.find(text=True))

This is totally OK.

1. The first group (m.group(0)) always captures the whole area that is covered by your regular expression. In this case, it's the whole string.
2. Regular expressions are greedy by default, meaning that the first group captures as much as possible without violating the regex. The (.*)(\\d+) (the first part of your regex) covers the ...QT300 int the first group and the 0 in the second.
3. You can quickly fix this by making the first group non-greedy: change (.*) to (.*?).

For more info on greedy vs. lazy, check this site.

If you have to log all args or your method have one argument, you can simply use getArgs like described in previous answers.

If you have to log a specific arg, you can annoted it and then recover its value like this :

@Retention(RetentionPolicy.RUNTIME)
@Target(ElementType.PARAMETER)
public @interface Data {
 String methodName() default "";
}

@Aspect
public class YourAspect {

 @Around("...")
 public Object around(ProceedingJoinPoint point) throws Throwable {
  Method method = MethodSignature.class.cast(point.getSignature()).getMethod();
  Object[] args = point.getArgs();
  StringBuilder data = new StringBuilder();
    Annotation[][] parameterAnnotations = method.getParameterAnnotations();
    for (int argIndex = 0; argIndex < args.length; argIndex++) {
        for (Annotation paramAnnotation : parameterAnnotations[argIndex]) {
            if (!(paramAnnotation instanceof Data)) {
                continue;
            }
            Data dataAnnotation = (Data) paramAnnotation;
            if (dataAnnotation.methodName().length() > 0) {
                Object obj = args[argIndex];
                Method dataMethod = obj.getClass().getMethod(dataAnnotation.methodName());
                data.append(dataMethod.invoke(obj));
                continue;
            }
            data.append(args[argIndex]);
        }
    }
 }
}

Examples of use :

public void doSomething(String someValue, @Data String someData, String otherValue) {
    // Apsect will log value of someData param
}

public void doSomething(String someValue, @Data(methodName = "id") SomeObject someData, String otherValue) {
    // Apsect will log returned value of someData.id() method
}

As documented in ?legend you do this like so:

plot(1:10,type = "n")
abline(v=seq(1,10,1), col='grey', lty='dotted')
legend(1, 5, "This legend text should not be disturbed by the dotted grey lines,\nbut the plotted dots should still be visible",box.lwd = 0,box.col = "white",bg = "white")
points(1:10,1:10)

Line breaks are achieved with the new line character \n. Making the points still visible is done simply by changing the order of plotting. Remember that plotting in R is like drawing on a piece of paper: each thing you plot will be placed on top of whatever's currently there.

Note that the legend text is cut off because I made the plot dimensions smaller (windows.options does not exist on all R platforms).

This question has been discussed so often on the Ruby mailing-lists and Ruby blogs that there are now even threads on the Ruby mailing-list whose only purpose is to collect links to all the other threads on the Ruby mailing-list that discuss this issue.

If you really want to know what is going on, take a look at Section 11.4.2.3 "Abbreviated assignments" of the Ruby Language Draft Specification.

As a first approximation,

a ||= b

is equivalent to

a || a = b

and not equivalent to

a = a || b

However, that is only a first approximation, especially if a is undefined. The semantics also differ depending on whether it is a simple variable assignment, a method assignment or an indexing assignment:

a    ||= b
a.c  ||= b
a[c] ||= b

are all treated differently.

$("video").prop('muted', true); //mute

AND

$("video").prop('muted', false); //unmute

You need to specify the minimum width of the field.

String.format("%" + numberOfSpaces + "s", ""); 

Why do you want to generate a String of spaces of a certain length.

If you want a column of this length with values then you can do:

String.format("%" + numberOfSpaces + "s", "Hello"); 

which gives you numberOfSpaces-5 spaces followed by Hello. If you want Hello to appear on the left then add a minus sign in before numberOfSpaces.

because the dir is not exist.

can use :!mkdir -p /etc/apt/ to make the directory.

There's certainly a performance difference when running a compiled script. If you run normal .py scripts, the machine compiles it every time it is run and this takes time. On modern machines this is hardly noticeable but as the script grows it may become more of an issue.

You can also use showdialog

Private Sub Button3_Click(sender As System.Object, e As System.EventArgs) _
                      Handles Button3.Click

     dim mydialogbox as new aboutbox1
     aboutbox1.showdialog()

End Sub

You could use Date.parse()

You can read in MDN documentation

The Date.parse() method parses a string representation of a date, and returns the number of milliseconds since January 1, 1970, 00:00:00 UTC or NaN if the string is unrecognized or, in some cases, contains illegal date values (e.g. 2015-02-31).

And check if the result of Date.parse isNaN

let isValidDate = Date.parse('01/29/1980');

if (isNaN(isValidDate)) {
  // when is not valid date logic

  return false;
}

// when is valid date logic

Please take a look when is recommended to use Date.parse in MDN

Try to include these lines on your code, after mych.Visible = true;:

1. textBoxName.Text = string.Empty;
2. textBoxName.Clear();

I needed to make report for a catering firm which serves lunches for various clients. In other words, catering may have on or more firms which take orders from catering, and it must know how many lunches it must produce every single day for all it's clients !

Just to notice, I didn't use sorting, in order not to over complicate this example.

This is my code :

@Test
public void test_2() throws Exception {
    Firm catering = DS.firm().get(1);
    LocalDateTime ldtFrom = LocalDateTime.of(2017, Month.JANUARY, 1, 0, 0);
    LocalDateTime ldtTo = LocalDateTime.of(2017, Month.MAY, 2, 0, 0);
    Date dFrom = Date.from(ldtFrom.atZone(ZoneId.systemDefault()).toInstant());
    Date dTo = Date.from(ldtTo.atZone(ZoneId.systemDefault()).toInstant());

    List<PersonOrders> LON = DS.firm().getAllOrders(catering, dFrom, dTo, false);
    Map<Object, Long> M = LON.stream().collect(
            Collectors.groupingBy(p
                    -> Arrays.asList(p.getDatum(), p.getPerson().getIdfirm(), p.getIdProduct()),
                    Collectors.counting()));

    for (Map.Entry<Object, Long> e : M.entrySet()) {
        Object key = e.getKey();
        Long value = e.getValue();
        System.err.println(String.format("Client firm :%s, total: %d", key, value));
    }
}

To add with @msandiford answer, as most of the times when a file tree is walked u may want to execute a function as a directory or any particular file is visited. If u are reluctant to using streams. The following methods overridden can be implemented

Files.walkFileTree(Paths.get(Krawl.INDEXPATH), EnumSet.of(FileVisitOption.FOLLOW_LINKS), Integer.MAX_VALUE,
    new SimpleFileVisitor<Path>() {
        @Override
        public FileVisitResult preVisitDirectory(Path dir, BasicFileAttributes attrs)
                throws IOException {
                // Do someting before directory visit
                return FileVisitResult.CONTINUE;
        }
        @Override
        public FileVisitResult visitFile(Path file, BasicFileAttributes attrs)
                throws IOException {
                // Do something when a file is visited
                return FileVisitResult.CONTINUE;
        }
        @Override
        public FileVisitResult postVisitDirectory(Path dir, IOException exc)
                throws IOException {
                // Do Something after directory visit 
                return FileVisitResult.CONTINUE;
        }
});

// get image from upload-image page 
public function postUplodeImage(Request $request)
{
    $this->validate($request, [
  // check validtion for image or file
        'uplode_image_file' => 'required|image|mimes:jpg,png,jpeg,gif,svg|max:2048',
    ]);
// rename image name or file name 

    $getimageName = time().'.'.$request->uplode_image_file->getClientOriginalExtension();
    $request->uplode_image_file->move(public_path('images'), $getimageName);
    return back()
        ->with('success','images Has been You uploaded successfully.')
        ->with('image',$getimageName);
}

I guess it's a matter of taste, although (mistakenly) mixing them up might cause some undesired behaviors:

true && false || false; // returns false

true and false || false; // returns true

Hence, using && and || is safer for they have the highest precedence. In what regards to readability, I'd say these operators are universal enough.

UPDATE: About the comments saying that both operations return false ... well, in fact the code above does not return anything, I'm sorry for the ambiguity. To clarify: the behavior in the second case depends on how the result of the operation is used. Observe how the precedence of operators comes into play here:

var_dump(true and false || false); // bool(false)

$a = true and false || false; var_dump($a); // bool(true)

The reason why $a === true is because the assignment operator has precedence over any logical operator, as already very well explained in other answers.

Maybe I am missing something here, but did you allocate any memory for that PString before you accessed it?

PString * initializeString() {
    PString *str;
    str = (PString *) malloc(sizeof(PString));
    str->length = &length;
    return str;
}

For me, the error was that I had:

    <android:support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"/>

instead of:

    <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"/>

Specifically, I had a colon between "android" and "support" on the first line instead of a period.

The statement def foo(client_id: str) -> list or bool: when evaluated is equivalent to def foo(client_id: str) -> list: and will therefore not do what you want.

The native way to describe a "either A or B" type hint is Union (thanks to Bhargav Rao):

def foo(client_id: str) -> Union[list, bool]:

I do not want to be the "Why do you want to do this anyway" guy, but maybe having 2 return types isn't what you want:

If you want to return a bool to indicate some type of special error-case, consider using Exceptions instead. If you want to return a bool as some special value, maybe an empty list would be a good representation. You can also indicate that None could be returned with Optional[list]

Add runat to the element in the markup

<div id="formSpinner" runat="server">
    <img src="images/spinner.gif">
    <p>Saving...</p>
</div

Then you can get to the control's class attributes by using formSpinner.Attributes("class") It will only be a string, but you should be able to edit it.

You can also create a new jsp file sayng that form is submited and in your main action file just write its file name

Eg. Your form is submited is in a file succes.jsp Then your action file will have

Request.sendRedirect("success.jsp")

You might want to try and set the supports-screens attribute:

<supports-screens
    android:largeScreens="true"
    android:normalScreens="true"
    android:smallScreens="true"
    android:xlargeScreens="true" >
</supports-screens>

The Wildfire has a small screen, and according to the documentation this attribute should default to "true" in all cases, but there are known issues with the supports-screens settings on different phones, so I would try this anyway.

Also - as David suggests - always compile and target against the most current version of the Android API, unless you have strong reasons not to. Pretty much every SDK prior to 2.2 has some serious issue or weird behavior; the latter SDK's help to resolve or cover up a lot (although not all) of them. You can (and should) use the Lint tool to check that your app remains compatible with API 4 when preparing a release.

Answering this after a long time...Came across the same situation and instead of using the answers mentioned, I came with below -

DELETE FROM table_name order by ID limit 10

This will delete the 1st 10 records and keep the latest records.

I don't think desc takes an na.rm argument... I'm actually surprised it doesn't throw an error when you give it one. If you just want to remove NAs, use na.omit (base) or tidyr::drop_na:

outcome.df %>%
  na.omit() %>%
  group_by(Hospital, State) %>%
  arrange(desc(HeartAttackDeath)) %>%
  head()

library(tidyr)
outcome.df %>%
  drop_na() %>%
  group_by(Hospital, State) %>%
  arrange(desc(HeartAttackDeath)) %>%
  head()

If you only want to remove NAs from the HeartAttackDeath column, filter with is.na, or use tidyr::drop_na:

outcome.df %>%
  filter(!is.na(HeartAttackDeath)) %>%
  group_by(Hospital, State) %>%
  arrange(desc(HeartAttackDeath)) %>%
  head()

outcome.df %>%
  drop_na(HeartAttackDeath) %>%
  group_by(Hospital, State) %>%
  arrange(desc(HeartAttackDeath)) %>%
  head()

As pointed out at the dupe, complete.cases can also be used, but it's a bit trickier to put in a chain because it takes a data frame as an argument but returns an index vector. So you could use it like this:

outcome.df %>%
  filter(complete.cases(.)) %>%
  group_by(Hospital, State) %>%
  arrange(desc(HeartAttackDeath)) %>%
  head()

Its a very old thread, but I don't see that the solution is here or the this thread is marked as solved. I have also stuck into the same problem I solved it like this

  $path = public_path('../storage/YOUR_FOLDER_NAME/YOUR_FILE_NAME');
  if (!File::exists($path)) 
  {
    File::delete(public_path('storage/YOUR_FOLDER_NAME/YOUR_FILE_NAME'));
  }

The key is that you need to remove '..' from the delete method. Keep in mind that this goes true if you are using Storage as well, whether you are using Storage of File don't for get to use them like

use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
use File; // For File
use Storage; // For Storage

Hope that it will help someone.

API(Application Programming Interface), the full form itself suggests that its an Interface which allows you to program for your application with the help or support of some other Application's Interface which exposes some sort of functionality which is useful to your application.

E.g showing updated currency exchange rates on your website would need some third party Interface to program against unless you plan to have your own database with currency rates and regular updates to the same. This set of functionality is when already available with some one else and when they want to share it with others they have to have an endpoint to communicate with the others who are interested in such interactions so they deploy it on web by the means of web-services. This end point is nothing but interface of their application which you can program against hence API.

Unique Keys: The columns in which no two rows are similar

Primary Key: Collection of minimum number of columns which can uniquely identify every row in a table (i.e. no two rows are similar in all the columns constituting primary key). There can be more than one primary key in a table. If there exists a unique-key then it is primary key (not "the" primary key) in the table. If there does not exist a unique key then more than one column values will be required to identify a row like (first_name, last_name, father_name, mother_name) can in some tables constitute primary key.

Index: used to optimize the queries. If you are going to search or sort the results on basis of some column many times (eg. mostly people are going to search the students by name and not by their roll no.) then it can be optimized if the column values are all "indexed" for example with a binary tree algorithm.

For zsh the syntax is slightly different, but still shorter than most answers here:

> str1='mAtCh'
> str2='MaTcH'
> [[ "$str1:u" = "$str2:u" ]] && echo 'Strings Match!'
Strings Match!
>

This will convert both strings to uppercase before the comparison.

Another method makes use zsh's globbing flags, which allows us to directly make use of case-insensitive matching by using the i glob flag:

setopt extendedglob
[[ $str1 = (#i)$str2 ]] && echo "Match success"
[[ $str1 = (#i)match ]] && echo "Match success"

Calculate x/y (your actual numbers here), and press a b/c key, which is 3rd one below Shift key.

The above answers do not fully answer the question (specifically the millisec part). My solution to this is to use gettimeofday before strftime. Note the care to avoid rounding millisec to "1000". This is based on Hamid Nazari's answer.

#include <stdio.h>
#include <sys/time.h>
#include <time.h>
#include <math.h>

int main() {
  char buffer[26];
  int millisec;
  struct tm* tm_info;
  struct timeval tv;

  gettimeofday(&tv, NULL);

  millisec = lrint(tv.tv_usec/1000.0); // Round to nearest millisec
  if (millisec>=1000) { // Allow for rounding up to nearest second
    millisec -=1000;
    tv.tv_sec++;
  }

  tm_info = localtime(&tv.tv_sec);

  strftime(buffer, 26, "%Y:%m:%d %H:%M:%S", tm_info);
  printf("%s.%03d\n", buffer, millisec);

  return 0;
}

Don't really know how they compare for speed, but the first one looks like the right idea for scaling to really big JSON data, since it parses only a small chunk at a time so they don't need to hold all the data in memory at once (This can be faster or slower depending on the library/use case)

1. If you have used an installer, you can uninstall golang by using the same installer.
2. If you have installed from source

   rm -rf /usr/local/go
   rm -rf $(echo $GOPATH)
   

Then, remove all entries related to go i.e. GOROOT, GOPATH from ~/.bash_profile and run

source ~/.bash_profile

On a Linux system

rm -rf /usr/local/go
rm -rf $(echo $GOPATH)

Then, remove all entries related to go i.e. GOROOT, GOPATH from ~/.bashrc and run

source ~/.bashrc

I just ran into this issue and checked all of the above answers to make sure I wasn't missing anything obvious. Well, I had a semi-obvious issue. My casing of my classname in code and the classname I used in the configuration file didn't match.

For example: if the class name is CalculatorService and the configuration file refers to Calculatorservice ... you will get this error.

I stumbled across this question while hitting this road block myself. I ended up writing a piece of code real quick to handle this ReDim Preserve on a new sized array (first or last dimension). Maybe it will help others who face the same issue.

So for the usage, lets say you have your array originally set as MyArray(3,5), and you want to make the dimensions (first too!) larger, lets just say to MyArray(10,20). You would be used to doing something like this right?

 ReDim Preserve MyArray(10,20) '<-- Returns Error

But unfortunately that returns an error because you tried to change the size of the first dimension. So with my function, you would just do something like this instead:

 MyArray = ReDimPreserve(MyArray,10,20)

Now the array is larger, and the data is preserved. Your ReDim Preserve for a Multi-Dimension array is complete. :)

And last but not least, the miraculous function: ReDimPreserve()

'redim preserve both dimensions for a multidimension array *ONLY
Public Function ReDimPreserve(aArrayToPreserve,nNewFirstUBound,nNewLastUBound)
    ReDimPreserve = False
    'check if its in array first
    If IsArray(aArrayToPreserve) Then       
        'create new array
        ReDim aPreservedArray(nNewFirstUBound,nNewLastUBound)
        'get old lBound/uBound
        nOldFirstUBound = uBound(aArrayToPreserve,1)
        nOldLastUBound = uBound(aArrayToPreserve,2)         
        'loop through first
        For nFirst = lBound(aArrayToPreserve,1) to nNewFirstUBound
            For nLast = lBound(aArrayToPreserve,2) to nNewLastUBound
                'if its in range, then append to new array the same way
                If nOldFirstUBound >= nFirst And nOldLastUBound >= nLast Then
                    aPreservedArray(nFirst,nLast) = aArrayToPreserve(nFirst,nLast)
                End If
            Next
        Next            
        'return the array redimmed
        If IsArray(aPreservedArray) Then ReDimPreserve = aPreservedArray
    End If
End Function

I wrote this in like 20 minutes, so there's no guarantees. But if you would like to use or extend it, feel free. I would've thought that someone would've had some code like this up here already, well apparently not. So here ya go fellow gearheads.

Without favouring any particular naming choice, remember that a git repo can be cloned into any root directory of your choice:

git clone https://github.com/user/repo.git myDir

Here repo.git would be cloned into the myDir directory.

So even if your naming convention for a public repo ended up to be slightly incorrect, it would still be possible to fix it on the client side.

That is why, in a distributed environment where any client can do whatever he/she wants, there isn't really a naming convention for Git repo.
(except to reserve "xxx.git" for bare form of the repo 'xxx')
There might be naming convention for REST service (similar to "Are there any naming convention guidelines for REST APIs?"), but that is a separate issue.

Or try pure ES6 nonlodash method like this

const reducer = (array, object) => {
  array.push(object.a)
  return array
}

var objects = [{ 'a': 1 }, { 'a': 2 }];
objects.reduce(reducer, [])

First, you don't declare the type in Ruby, so you don't need the first string.

To replace a word in string, you do: sentence.gsub(/match/, "replacement").

I personally prefer the "boolean1 ^ boolean2" expression due to its succinctness.

If I was in your situation (working in a team), I would strike a compromise by encapsulating the "boolean1 ^ boolean2" logic in a function with a descriptive name such as "isDifferent(boolean1, boolean2)".

For example, instead of using "boolean1 ^ boolean2", you would call "isDifferent(boolean1, boolean2)" like so:

if (isDifferent(boolean1, boolean2))
{
  //do it
}

Your "isDifferent(boolean1, boolean2)" function would look like:

private boolean isDifferent(boolean1, boolean2)
{
    return boolean1 ^ boolean2;
}

Of course, this solution entails the use of an ostensibly extraneous function call, which in itself is subject to Best Practices scrutiny, but it avoids the verbose (and ugly) expression "(boolean1 && !boolean2) || (boolean2 && !boolean1)"!

I once was where you are right now, as a beginner you sometimes feel out of place on how the react way to do this. I'm gonna try to tackle the same way I think of it right now.

States are the cornerstone for communication

Usually what it comes down to is the way that you alter the states in this component in your case you point out three components.

<List /> : Which probably will display a list of items depending on a filter <Filters />: Filter options that will alter your data. <TopBar />: List of options.

To orchestrate all of this interaction you are going to need a higher component let's call it App, that will pass down actions and data to each one of this components so for instance can look like this

<div>
  <List items={this.state.filteredItems}/>
  <Filter filter={this.state.filter} setFilter={setFilter}/>
</div>

So when setFilter is called it will affect the filteredItem and re-render both component;. In case this is not entirely clear I made you an example with checkbox that you can check in a single file:

import React, {Component} from 'react';
import {render} from 'react-dom';

const Person  = ({person, setForDelete}) => (
          <div>
            <input type="checkbox" name="person" checked={person.checked} onChange={setForDelete.bind(this, person)} />
            {person.name}
          </div>
);


class PeopleList extends Component {

  render() {

    return(
      <div>
       {this.props.people.map((person, i) => {
         return <Person key={i} person={person} setForDelete={this.props.setForDelete} />;
       })}
       <div onClick={this.props.deleteRecords}>Delete Selected Records</div>
     </div>
    );
  }

} // end class

class App extends React.Component {

  constructor(props) {
    super(props)
    this.state = {people:[{id:1, name:'Cesar', checked:false},{id:2, name:'Jose', checked:false},{id:3, name:'Marbel', checked:false}]}
  }

  deleteRecords() {
    const people = this.state.people.filter(p => !p.checked);

    this.setState({people});
 }

  setForDelete(person) {
    const checked = !person.checked;
    const people = this.state.people.map((p)=>{
      if(p.id === person.id)
        return {name:person.name, checked};
      return p;
    });

    this.setState({people});
  }

  render () {

    return <PeopleList people={this.state.people} deleteRecords={this.deleteRecords.bind(this)} setForDelete={this.setForDelete.bind(this)}/>;
  }
}

render(<App/>, document.getElementById('app'));

One way to speed things up is to explicitly perform multiple inserts or copy's within a transaction (say 1000). Postgres's default behavior is to commit after each statement, so by batching the commits, you can avoid some overhead. As the guide in Daniel's answer says, you may have to disable autocommit for this to work. Also note the comment at the bottom that suggests increasing the size of the wal_buffers to 16 MB may also help.

function a(a, b) {
    return a + b
};

function call_a() {
    return a.apply(a, Array.prototype.slice.call(arguments, 0));
}

console.log(call_a(1, 2))

console: 3

In Relational algebra 'Selection' and 'Projection' are different operations, but the SQL SELECT combines these operations in a single statement.

Select retrieves the tuples (rows) in a relation (table) for which the condition in 'predicate' section (WHERE clause) stands true.

Project retrieves the attributes (columns) specified.

The following SQL SELECT query:

select field1,field2 from table1 where field1 = 'Value';

is a combination of both Projection and Selection operations of relational algebra.

We do not need to use recursive method, it may be slow. My solution is using a user-defined function rint instesd of instrinsic function int or floor.

rint(x)=(x-int(x)>0.9999)?int(x)+1:int(x)

This function will give rint(0.0003/0.0001)=3, while int(0.0003/0.0001)=floor(0.0003/0.0001)=2.

Why? Please look at Perl int function and padding zeros

This work for Checkbox too.

public class EnumToBoolConverter:IValueConverter
{
    private int val;
    public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
    {
        int intParam = (int)parameter;
        val = (int)value;

        return ((intParam & val) != 0);
    }

    public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
    {
        val ^= (int)parameter;
        return Enum.Parse(targetType, val.ToString());
    }
}

Binding a single enum to multiple checkboxes.

See ?assign.

I think it's a lot easier to use NSNumbers. This all you need to do:

NSNumber *myNum1 = [NSNumber numberWithInt:myNsIntValue1];
NSNumber *myNum2 = [NSNumber numberWithInt:myNsIntValue2];
.
.
.
NSArray *myArray = [NSArray arrayWithObjects: myNum1, myNum2, ..., nil];

ptomato's code can also be written in a cleaner manner like:

ifeq ($(TARGET_CPU),x86)
  TARGET_CPU_IS_X86 := 1
else ifeq ($(TARGET_CPU),x86_64)
  TARGET_CPU_IS_X86 := 1
else
  TARGET_CPU_IS_X86 := 0
endif

This doesn't answer OP's question but as it's the top result on google, I'm adding it here in case it's useful to anyone else.

This way you can remove 1 leading "[" and 1 trailing "]" character. If your string happen to not start with "[" or end with "]" it won't remove anything:

str.replaceAll("^\\[|\\]$", "")

No, what you are looking for would be called a parent selector. CSS has none; they have been proposed multiple times but I know of no existing or forthcoming standard including them. You are correct that you would need to use something like jQuery or use additional class annotations to achieve the effect you want.

Here are some similar questions with similar results:

• Is there a CSS parent selector?
• CSS Parent/Ancestor Selector
• Complex CSS selector for parent of active child

From the Docker FAQ:

Docker is not a replacement for lxc. "lxc" refers to capabilities of the linux kernel (specifically namespaces and control groups) which allow sandboxing processes from one another, and controlling their resource allocations.

On top of this low-level foundation of kernel features, Docker offers a high-level tool with several powerful functionalities:

• Portable deployment across machines. Docker defines a format for bundling an application and all its dependencies into a single object which can be transferred to any docker-enabled machine, and executed there with the guarantee that the execution environment exposed to the application will be the same. Lxc implements process sandboxing, which is an important pre-requisite for portable deployment, but that alone is not enough for portable deployment. If you sent me a copy of your application installed in a custom lxc configuration, it would almost certainly not run on my machine the way it does on yours, because it is tied to your machine's specific configuration: networking, storage, logging, distro, etc. Docker defines an abstraction for these machine-specific settings, so that the exact same docker container can run - unchanged - on many different machines, with many different configurations.

• Application-centric. Docker is optimized for the deployment of applications, as opposed to machines. This is reflected in its API, user interface, design philosophy and documentation. By contrast, the lxc helper scripts focus on containers as lightweight machines - basically servers that boot faster and need less ram. We think there's more to containers than just that.

• Automatic build. Docker includes a tool for developers to automatically assemble a container from their source code, with full control over application dependencies, build tools, packaging etc. They are free to use make, maven, chef, puppet, salt, debian packages, rpms, source tarballs, or any combination of the above, regardless of the configuration of the machines.

• Versioning. Docker includes git-like capabilities for tracking successive versions of a container, inspecting the diff between versions, committing new versions, rolling back etc. The history also includes how a container was assembled and by whom, so you get full traceability from the production server all the way back to the upstream developer. Docker also implements incremental uploads and downloads, similar to "git pull", so new versions of a container can be transferred by only sending diffs.

• Component re-use. Any container can be used as an "base image" to create more specialized components. This can be done manually or as part of an automated build. For example you can prepare the ideal python environment, and use it as a base for 10 different applications. Your ideal postgresql setup can be re-used for all your future projects. And so on.

• Sharing. Docker has access to a public registry (https://registry.hub.docker.com/) where thousands of people have uploaded useful containers: anything from redis, couchdb, postgres to irc bouncers to rails app servers to hadoop to base images for various distros. The registry also includes an official "standard library" of useful containers maintained by the docker team. The registry itself is open-source, so anyone can deploy their own registry to store and transfer private containers, for internal server deployments for example.

• Tool ecosystem. Docker defines an API for automating and customizing the creation and deployment of containers. There are a huge number of tools integrating with docker to extend its capabilities. PaaS-like deployment (Dokku, Deis, Flynn), multi-node orchestration (maestro, salt, mesos, openstack nova), management dashboards (docker-ui, openstack horizon, shipyard), configuration management (chef, puppet), continuous integration (jenkins, strider, travis), etc. Docker is rapidly establishing itself as the standard for container-based tooling.

I hope this helps!

mainWB.Sheets.Add(After:=Sheets(Sheets.Count)).Name = new_sheet_name 

should probably be

mainWB.Sheets.Add(After:=mainWB.Sheets(mainWB.Sheets.Count)).Name = new_sheet_name 

Supplier with a one-to-many relationship with Product. One Supplier has (supplies) many Products.

***** Table: Supplier *****
+-----+-------------------+
| ID  |       NAME        |
+-----+-------------------+
|  1  |  Supplier Name 1  |
|  2  |  Supplier Name 2  |
|  3  |  Supplier Name 3  |
|  4  |  Supplier Name 4  |
+-----+-------------------+

***** Table: Product *****
+-----+-----------+--------------------+-------+------------+
| ID  |   NAME    |     DESCRIPTION    | PRICE | SUPPLIERID |
+-----+-----------+--------------------+-------+------------+
|1    | Product 1 | Name for Product 1 |  2.0  |     1      |
|2    | Product 2 | Name for Product 2 | 22.0  |     1      |
|3    | Product 3 | Name for Product 3 | 30.0  |     2      |
|4    | Product 4 | Name for Product 4 |  7.0  |     3      |
+-----+-----------+--------------------+-------+------------+

Factors:

• Lazy mode for Supplier set to “true” (default)

• Fetch mode used for querying on Product is Select

• Fetch mode (default): Supplier information is accessed

• Caching does not play a role for the first time the

• Supplier is accessed

Fetch mode is Select Fetch (default)

// It takes Select fetch mode as a default
Query query = session.createQuery( "from Product p");
List list = query.list();
// Supplier is being accessed
displayProductsListWithSupplierName(results);

select ... various field names ... from PRODUCT
select ... various field names ... from SUPPLIER where SUPPLIER.id=?
select ... various field names ... from SUPPLIER where SUPPLIER.id=?
select ... various field names ... from SUPPLIER where SUPPLIER.id=?

Result:

• 1 select statement for Product
• N select statements for Supplier

This is N+1 select problem!

• This solution uses csv-parser instead of csv-parse used in some of the answers above.
• csv-parser came around 2 years after csv-parse.
• Both of them solve the same purpose, but personally I have found csv-parser better, as it is easy to handle headers through it.

Install the csv-parser first:

npm install csv-parser

So suppose you have a csv-file like this:

NAME, AGE
Lionel Messi, 31
Andres Iniesta, 34

You can perform the required operation as:

const fs = require('fs'); 
const csv = require('csv-parser');

fs.createReadStream(inputFilePath)
.pipe(csv())
.on('data', function(data){
    try {
        console.log("Name is: "+data.NAME);
        console.log("Age is: "+data.AGE);

        //perform the operation
    }
    catch(err) {
        //error handler
    }
})
.on('end',function(){
    //some final operation
});

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

Right now it's working for me.

example:

App.js

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



class App extends Component {

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

export default App;

App.css

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

You can also use chmod 777 *

This will give permissions to all files currently in the folder and files added in the future without giving permissions to the directory itself.

NOTE: This should be done in the folder where the files are located. For me it was an images that had an issue so I went to my images folder and did this.

There is a concurrent list implementation in java.util.concurrent. CopyOnWriteArrayList in particular.

    new String(new char[] { 65 })

You will end up with a string of length one, whose single character has the (ASCII) code 65. In Java chars are numeric data types.

I modified the answer from rayzinnz to end the script with a specific key, in this case the escape key

In Java 8 you can do it like this:

import java.util.*;
import java.util.stream.*;

List<JsonNode> datasets = StreamSupport
    .stream(datasets.get("datasets").spliterator(), false)
    .collect(Collectors.toList())

In my case I had:

Referenced DLL : .NET 4.5

Project : .NET 4.0

Because of the above mismatch, the 4.0 project couldn't see inside the namespace of the 4.5 .DLL. I recompiled the .DLL to target .NET 4.0 and I was fine.

I ran into this issue with Python 3.6 and Python 3.7. The top answer (running pip install --upgrade pip enum34) did not solve the problem.

I don't know why, but the reason why this error happen is because enum.py was missing from .venv/myvenv/lib/python3.7/.

But the file was in /usr/lib/python3.7/.

Following this answer, I just created the symbolic link by myself :

ln -s /usr/lib/python3.7/enum.py .venv/myvenv/lib/python3.7/enum.py

If you can't use the delay method as Robert Harvey suggested, you can use setTimeout.

Eg.

setTimeout(function() {$("#test").animate({"top":"-=80px"})} , 1500); // delays 1.5 sec
setTimeout(function() {$("#test").animate({"opacity":"0"})} , 1500 + 1000); // delays 1 sec after the previous one

There is only a small amount of information that you can get via an HTTP connection.

1. IP - But as others have said, this is not fixed for many, if not most Internet users due to their ISP's dynamic allocation policies.

2. Useragent String - Nearly all browsers send what kind of browser they are with every request. However, this can be set by the user in many browsers today.

3. Collection of request fields - There are other fields sent with each request, such as supported encodings, etc. These, if used in the aggregate can help to ID a user's machine, but again are browser dependent and can be changed.

4. Cookies - Setting a cookie is another way to identify a machine, or more specifically a browser on a machine, but as others have said, these can be deleted, or turned off by the users, and are only applicable on a browser, not a machine.

So, the correct response is that you cannot achieve what you would live via the HTTP over IP protocols alone. However, using a combination of cookies, as well as IP, and the fields in the HTTP request, you have a good chance at guessing, sort of, what machine it is. Users tend to use only one browser, and often from one machine, so this may be fairly relieable, but this will vary depending on the audience...techies are more likely to mess with this stuff, and use more machines/browsers. Additionally, this could even be coupled with some attempt to geo-locate the IP, and use that data as well. But in any case, there is no solution that will be correct all of the time.

Open the path/to/your/rails/project/tmp/pids/server.pid file.

Copy the number you find therein.

Run kill -9 [PID]

Where [PID] is the number you copied from the server.pid file.

This will kill the running server process and you can start your server again without any trouble.

On the Terminal, type:

echo "$JAVA_HOME"

If you are not getting anything, then your environment variable JAVA_HOME has not been set. You can try using "locate java" to try and discover where your installation of Java is located.

This could better be done as

x="\n"
echo -ne $x

-e option will interpret backslahes for the escape sequence
-n option will remove the trailing newline in the output

PS: the command echo has an effect of always including a trailing newline in the output so -n is required to turn that thing off (and make it less confusing)

The issue HttpServletRequest.login does not set authentication state in session has been fixed in 3.0.1. Update glassfish to the latest version and you're done.

Updating is quite straightforward:

glassfishv3/bin/pkg set-authority -P dev.glassfish.org
glassfishv3/bin/pkg image-update

same thing JUST happened to me with NUGET.

the following tag helped

Also if this is happening on the server, I had to make sure I was running the application pool on a more "privileged account" to the file system, but I don think that's your issue here

The SQLite command line utility has a .schema TABLENAME command that shows you the create statements.

In Eclipse do the following:

GIT Repositories > Remotes > Origin > Right click and say fetch

GIT Repositories > Remote Tracking > Select your branch and say merge

Go to project, right click on your file and say Fetch from upstream.

This example might be seem a bit lengthy, but its intention should be quite clear.

It uses 3 Boolean properties in the ViewModel called, FlagForValue1, FlagForValue2 and FlagForValue3. Each of these 3 properties is backed by a single private field called _intValue.

The 3 Radio buttons of the view (xaml) are each bound to its corresponding Flag property in the view model. This means the radio button displaying "Value 1" is bound to the FlagForValue1 bool property in the view model and the other two accordingly.

When setting one of the properties in the view model (e.g. FlagForValue1), its important to also raise property changed events for the other two properties (e.g. FlagForValue2, and FlagForValue3) so the UI (WPF INotifyPropertyChanged infrastructure) can selected / deselect each radio button correctly.

    private int _intValue;

    public bool FlagForValue1
    {
        get
        {
            return (_intValue == 1) ? true : false;
        }
        set
        {
            _intValue = 1;
            RaisePropertyChanged("FlagForValue1");
            RaisePropertyChanged("FlagForValue2");
            RaisePropertyChanged("FlagForValue3");
        }
    }

    public bool FlagForValue2
    {
        get
        {
            return (_intValue == 2) ? true : false;
        }
        set
        {
            _intValue = 2;
            RaisePropertyChanged("FlagForValue1");
            RaisePropertyChanged("FlagForValue2");
            RaisePropertyChanged("FlagForValue3");
        }
    }

    public bool FlagForValue3
    {
        get
        {
            return (_intValue == 3) ? true : false;
        }
        set
        {
            _intValue = 3;
            RaisePropertyChanged("FlagForValue1");
            RaisePropertyChanged("FlagForValue2");
            RaisePropertyChanged("FlagForValue3");
        }
    }

The xaml looks like this:

                <RadioButton GroupName="Search" IsChecked="{Binding Path=FlagForValue1, Mode=TwoWay}"
                             >Value 1</RadioButton>

                <RadioButton GroupName="Search" IsChecked="{Binding Path=FlagForValue2, Mode=TwoWay}"
                             >Value 2</RadioButton>

                <RadioButton GroupName="Search" IsChecked="{Binding Path=FlagForValue3, Mode=TwoWay}"
                             >Value 3</RadioButton>

There's a situation where the cell has white space, you can't see it, use

df['col'].replace('  ', np.nan, inplace=True)

to replace white space as NaN, then

df= df.dropna(subset=['col'])

I recommend using https://www.npmjs.com/package/express-es6-template-engine - extremely lightwave and blazingly fast template engine. The name is a bit misleading as it can work without expressjs too.

The basics required to integrate express-es6-template-engine in your app are pretty simple and quite straight forward to implement:

const express = require('express'),_x000D_
  es6Renderer = require('express-es6-template-engine'),_x000D_
  app = express();_x000D_
  _x000D_
app.engine('html', es6Renderer);_x000D_
app.set('views', 'views');_x000D_
app.set('view engine', 'html');_x000D_
 _x000D_
app.get('/', function(req, res) {_x000D_
  res.render('index', {locals: {title: 'Welcome!'}});_x000D_
});_x000D_
 _x000D_
app.listen(3000);

You can use inbuilt library pickle

This library allows you to save any object in python to a file

This library will maintain the format as well

import pickle
with open('/content/list_1.txt', 'wb') as fp:
    pickle.dump(list_1, fp)

you can also read the list back as an object using same library

with open ('/content/list_1.txt', 'rb') as fp:
    list_1 = pickle.load(fp)

reference : Writing a list to a file with Python

This should do it. You were missing a ) and you only need """ not 4 of them. Also you don't need a elif at the end.

ans=True
while ans:
    print("""
    1.Add a Student
    2.Delete a Student
    3.Look Up Student Record
    4.Exit/Quit
    """)
    ans=raw_input("What would you like to do? ")
    if ans=="1":
      print("\nStudent Added")
    elif ans=="2":
      print("\n Student Deleted")
    elif ans=="3":
      print("\n Student Record Found")
    elif ans=="4":
      print("\n Goodbye") 
      ans = None
    else:
       print("\n Not Valid Choice Try again")

Use --build-arg with each argument.

If you are passing two argument then add --build-arg with each argument like:

docker build \
-t essearch/ess-elasticsearch:1.7.6 \
--build-arg number_of_shards=5 \
--build-arg number_of_replicas=2 \
--no-cache .

The return statement only makes sense inside functions:

def foo():
    while True:
        return False

This website will decompile the code embedded in APK files and extract all the other assets in the file.

You could try changing the button attribute like this:

element.setAttribute( "onClick", "javascript: Boo();" );

Nice explanation from http://www.journaldev.com/753/how-to-copy-arrays-in-java

Java Array Copy Methods

Object.clone(): Object class provides clone() method and since array in java is also an Object, you can use this method to achieve full array copy. This method will not suit you if you want partial copy of the array.

System.arraycopy(): System class arraycopy() is the best way to do partial copy of an array. It provides you an easy way to specify the total number of elements to copy and the source and destination array index positions. For example System.arraycopy(source, 3, destination, 2, 5) will copy 5 elements from source to destination, beginning from 3rd index of source to 2nd index of destination.

Arrays.copyOf(): If you want to copy first few elements of an array or full copy of array, you can use this method. Obviously it’s not versatile like System.arraycopy() but it’s also not confusing and easy to use.

Arrays.copyOfRange(): If you want few elements of an array to be copied, where starting index is not 0, you can use this method to copy partial array.

I have a far more simple solution, it is working for me; it is also a workaround but might be usable and you dont have to change your settings. I assume you can use value that will never be there, then you use it on your WHERE clause

DELETE FROM MyTable WHERE MyField IS_NOT_EQUAL AnyValueNoItemOnMyFieldWillEverHave

I don't like that solution either too much, that's why I am here, but it works and it seems better than what it has been answered

The equals() method on your List implementation should do elementwise comparison, so

assertEquals(argumentComponents, returnedComponents);

is a lot easier.

If it's possible, you can build the position array using find function, and then sort the array.

Or maybe you can use a map where the key would be the element, and the values a list of its position in the upcoming arrays (A, B and C)

It depends on later uses of those arrays.

It should be document.getElementById("hidden").style.display = "block"; not document.getElementById["hidden"].style.display = "block";

EDIT due to author edit:

Why are you using a <div> here? Just add an ID to the table element and add a hidden style to it. E.g. <td id="hidden" style="display:none" class="depot_table_left">

The fastest and imho easiest solution that works in any environment is:

<?php

namespace \My\Awesome\Namespace;

class Foo {

  private $shortName;

  public function fastShortName() {
    if ($this->shortName === null) {
      $this->shortName = explode("\\", static::class);
      $this->shortName = end($this->shortName);
    }
    return $this->shortName;
  }

  public function shortName() {
    return basename(strtr(static::class, "\\", "/"));
  }

}

echo (new Foo())->shortName(); // "Foo"

?>

If you have a radio button with same id, then you can clear the selection

Radio Button definition :

<input type="radio" name="paymentType" id="paymentType" value="CASH" /> CASH
<input type="radio" name="paymentType" id="paymentType" value="CHEQUE" /> CHEQUE
<input type="radio" name="paymentType" id="paymentType" value="DD" /> DD

Clearing all values of radio button:

document.formName.paymentType[0].checked = false;
document.formName.paymentType[1].checked = false;
document.formName.paymentType[2].checked = false;
...

git pull origin master

this will sync your master to the central repo and if new branches are pushed to the central repo it will also update your clone copy.

This isn't exactly the issue I had, but if anyone is looking to convert a BindingList of any type to List of the same type, then this is how it is done:

var list = bindingList.ToDynamicList();

Also, if you're assigning BindingLists of dynamic types to a DataGridView.DataSource, then make sure you declare it first as IBindingList so the above works.

Just execute the set command in your command line. Then you see all the environments variables you have set.

Or if on Unix you can simplify it:

$ set | grep "JAVA_HOME" 

You have mixed 2 standard.

The error is in $header = "Content-Type: multipart/form-data; boundary='123456f'";

The function http_build_query($filedata) is only for "Content-Type: application/x-www-form-urlencoded", or none.

Let's clarify first what is a CPU and what is a core, a central processing unit CPU, can have multiple core units, those cores are a processor by itself, capable of execute a program but it is self contained on the same chip.

In the past one CPU was distributed among quite a few chips, but as Moore's Law progressed they made to have a complete CPU inside one chip (die), since the 90's the manufacturer's started to fit more cores in the same die, so that's the concept of Multi-core.

In these days is possible to have hundreds of cores on the same CPU (chip or die) GPUs, Intel Xeon. Other technique developed in the 90's was simultaneous multi-threading, basically they found that was possible to have another thread in the same single core CPU, since most of the resources were duplicated already like ALU, multiple registers.

So basically a CPU can have multiple cores each of them capable to run one thread or more at the same time, we may expect to have more cores in the future, but with more difficulty to be able to program efficiently.

The Pro Git book mentions:

Tracking branches are local branches that have a direct relationship to a remote branch

Not exactly. The SO question "Having a hard time understanding git-fetch" includes:

There's no such concept of local tracking branches, only remote tracking branches.
So origin/master is a remote tracking branch for master in the origin repo.

But actually, once you establish an upstream branch relationship between:

• a local branch like master
• and a remote tracking branch like origin/master

Then you can consider master as a local tracking branch: It tracks the remote tracking branch origin/master which, in turn, tracks the master branch of the upstream repo origin.

The problem with Javascript's MIME type is that there hasn't been a standard for years. Now we've got application/javascript as an official MIME type.

But actually, the MIME type doesn't matter at all, as the browser can determine the type itself. That's why the HTML5 specs state that the type="text/javascript" is no longer required.

I found the answer is very very simple...

// It is in java, but it should be same in pyspark
Column col = ds.col("colName"); //the column object
String theNameOftheCol = col.toString();

The variable "theNameOftheCol" is "colName"

If you are making apps that require dangerous permissions and set targetSDK to 23 or above you should be careful. If you do not check permissions on runtime you will get a SecurityException and if you are using code inside a try block, for example open camera, it can be hard to detect error if you do not check logcat.

It seems that you have invalid JSON. In that case, that's totally dependent on the data the server sends you which you have not shown. I would suggest running the response through a JSON validator.

This can happen for several reasons, including:

1. The CA that issued the server certificate was unknown
2. The server certificate wasn't signed by a CA, but was self signed
3. The server configuration is missing an intermediate CA

def nans(df): return df[df.isnull().any(axis=1)]

then when ever you need it you can type:

nans(your_dataframe)

I think you are confusing objects and classes. A class inside a class looks like this:

class Foo(object):
    class Bar(object):
        pass

>>> foo = Foo()
>>> bar = Foo.Bar()

But it doesn't look to me like that's what you want. Perhaps you are after a simple containment hierarchy:

class Player(object):
    def __init__(self, ... airplanes ...) # airplanes is a list of Airplane objects
        ...
        self.airplanes = airplanes
        ...

class Airplane(object):
    def __init__(self, ... flights ...) # flights is a list of Flight objects
        ...
        self.flights = flights
        ...

class Flight(object):
    def __init__(self, ... duration ...)
        ...
        self.duration = duration
        ...

Then you can build and use the objects thus:

player = Player(...[
    Airplane(... [
        Flight(...duration=10...),
        Flight(...duration=15...),
        ] ... ),
    Airplane(...[
        Flight(...duration=20...),
        Flight(...duration=11...),
        Flight(...duration=25...),
        ]...),
    ])

player.airplanes[5].flights[6].duration = 5

When I trying to my login (which is a bootstrap modal), I used the @sessionattributes annotation. But problem was when the view is a redirect ("redirect:/home"), values I entered to session shows in the url. Some Internet sources suggest to follow http://docs.spring.io/spring/docs/4.3.x/spring-framework-reference/htmlsingle/#mvc-redirecting But I used the HttpSession instead. This session will be there until you close the browsers. Here is sample code

        @RequestMapping(value = "/login")
        @ResponseBody
        public BooleanResponse login(HttpSession session,HttpServletRequest request){
            //HttpServletRequest used to take data to the controller
            String username = request.getParameter("username");
            String password = request.getParameter("password");

           //Here you set your values to the session
           session.setAttribute("username", username);
           session.setAttribute("email", email);

          //your code goes here
}

You don't change specific thing on view side.

<c:out value="${username}"></c:out>
<c:out value="${email}"></c:out>

After login add above codes to anyplace in you web site. If session correctly set, you will see the values there. Make sure you correctly added the jstl tags and El- expressions (Here is link to set jstl tags https://menukablog.wordpress.com/2016/05/10/add-jstl-tab-library-to-you-project-correctly/)

datetime.datetime.strptime has problems with timezone parsing. Have a look at the dateutil package:

>>> from dateutil import parser
>>> parser.parse("Tue May 08 15:14:45 +0800 2012")
datetime.datetime(2012, 5, 8, 15, 14, 45, tzinfo=tzoffset(None, 28800))

It does work indeed. Issue was with my less compiler. It was compiled in to:

.container {
  min-height: calc(-51vh);
}

Fixed with the following code in less file:

.container {
  min-height: calc(~"100vh - 150px");
}

Thanks to this link: Less Aggressive Compilation with CSS3 calc
