If you are using laragon open the php.ini

In the interface of laragon menu-> php-> php.ini

when you open the file look for ; extension_dir = "./"

create another one without **; ** with the path of your php version to the folder ** ext ** for example

extension_dir = "C: \ laragon \ bin \ php \ php-7.3.11-Win32-VC15-x64 \ ext"

change it save it

In most database systems, IN (val1, val2, …) and a series of OR are optimized to the same plan.

The third way would be importing the list of values into a temporary table and join it which is more efficient in most systems, if there are lots of values.

• Passing parameters in MySQL: IN list vs. temporary table

S.Lott inserted a comment, but it should be an answer: see the same question.

EDIT

Since it wasn't as obvious as I intended it to be, here follows a verbatim copy of S.Lott's answer in the other question:

I'm a big fan of ARGO UML from Tigris.org. Draws nice pictures using standard UML notation. It does some code generation, but mostly Java classes, which isn't SQL DDL, so that may not be close enough to what you want to do.

You can look at the Data Modelling Tools list and see if anything there is better than Argo UML. Many of the items on this list are free or cheap.

Also, if you're using Eclipse or NetBeans, there are many design plug-ins, some of which may have the features you're looking for.

IMHO, the reason why 2 queries

SELECT * FROM count_test WHERE b = 666 ORDER BY c LIMIT 5;
SELECT count(*) FROM count_test WHERE b = 666;

are faster than using SQL_CALC_FOUND_ROWS

SELECT SQL_CALC_FOUND_ROWS * FROM count_test WHERE b = 555 ORDER BY c LIMIT 5;

has to be seen as a particular case.

It in facts depends on the selectivity of the WHERE clause compared to the selectivity of the implicit one equivalent to the ORDER + LIMIT.

As Arvids told in comment (http://www.mysqlperformanceblog.com/2007/08/28/to-sql_calc_found_rows-or-not-to-sql_calc_found_rows/#comment-1174394), the fact that the EXPLAIN use, or not, a temporay table, should be a good base for knowing if SCFR will be faster or not.

But, as I added (http://www.mysqlperformanceblog.com/2007/08/28/to-sql_calc_found_rows-or-not-to-sql_calc_found_rows/#comment-8166482), the result really, really depends on the case. For a particular paginator, you could get to the conclusion that “for the 3 first pages, use 2 queries; for the following pages, use a SCFR” !

ucfagls is right, providing you use the plot() command. If not, please give us more detail.

In any case, you can control every axis seperately by using the axis() command and the xaxt/yaxt options in plot(). Using the data of ucfagls, this becomes :

plot(Y ~ X, data=foo,yaxt="n")
axis(2,cex.axis=2)

the option yaxt="n" is necessary to avoid that the plot command plots the y-axis without changing. For the x-axis, this works exactly the same :

plot(Y ~ X, data=foo,xaxt="n")
axis(1,cex.axis=2)

See also the help files ?par and ?axis

Edit : as it is for a barplot, look at the options cex.axis and cex.names :

tN <- table(sample(letters[1:5],100,replace=T,p=c(0.2,0.1,0.3,0.2,0.2)))

op <- par(mfrow=c(1,2))
barplot(tN, col=rainbow(5),cex.axis=0.5) # for the Y-axis
barplot(tN, col=rainbow(5),cex.names=0.5) # for the X-axis
par(op)

I had a problem with an element which had to be colored RED on hover and be BLUE on click while being hovered. To achieve this with css you need for example:

h1:hover { color: red; } 
h1:active { color: blue; }

<h1>This is a heading.</h1>

I struggled for some time until I discovered that the order of CSS selectors was the problem I was having. The problem was that I switched the places and the active selector was not working. Then I found out that :hover to go first and then :active.

To reference range of cells you can use Range(Cell1,Cell2), sample:

Sub RangeTest()
  Dim testRange As Range
  Dim targetWorksheet As Worksheet
  
  Set targetWorksheet = Worksheets("MySheetName")
  
  With targetWorksheet
    .Cells(5, 10).Select 'selects cell J5 on targetWorksheet
    Set testRange = .Range(.Cells(5, 5), .Cells(10, 10))
  End With
  
  testRange.Select 'selects range of cells E5:J10 on targetWorksheet
  
End Sub

PROBABLY ONLY IE:

>     webBrowser1.DocumentText

for FF up from 1.0:

//serialize current DOM-Tree incl. changes/edits to ss-variable
var ns = new XMLSerializer();
var ss= ns.serializeToString(document);
alert(ss.substr(0,300));

may work in FF. (Shows up the VERY FIRST 300 characters from the VERY beginning of source-text, mostly doctype-defs.)

BUT be aware, that the normal "Save As"-Dialog of FF MIGHT NOT save the current state of the page, rather the originallly loaded X/h/tml-source-text !! (a POST-up of ss to some temp-file and redirect to that might deliver a saveable source-text WITH the changes/edits prior made to it.)

Although FF surprises by good recovery on "back" and a NICE inclusion of states/values on "Save (as) ..." for input-like FIELDS, textarea etc. , not on elements in contenteditable/ designMode...

If NOT a xhtml- resp. xml-file (mime-type, NOT just filename-extension!), one may use document.open/write/close to SET the appr. content to the source-layer, that will be saved on user's save-dialog from the File/Save menue of FF. see: http://www.w3.org/MarkUp/2004/xhtml-faq#docwrite resp.

Neutral to questions of X(ht)ML, try a "view-source:http://..." as the value of the src-attrib of an (script-made!?) iframe, - to access an iframes-document in FF:

<iframe-elementnode>.contentDocument, see google "mdn contentDocument" for appr. members, like 'textContent' for instance. 'Got that years ago and no like to crawl for it. If still of urgent need, mention this, that I got to dive in ...

All of these answers appear to be incomplete and/or kludges. Looking at the RestTemplate interface, it sure looks like it is intended to have a ClientHttpRequestFactory injected into it, and then that requestFactory will be used to create the request, including any customizations of headers, body, and request params.

You either need a universal ClientHttpRequestFactory to inject into a single shared RestTemplate or else you need to get a new template instance via new RestTemplate(myHttpRequestFactory).

Unfortunately, it looks somewhat non-trivial to create such a factory, even when you just want to set a single Authorization header, which is pretty frustrating considering what a common requirement that likely is, but at least it allows easy use if, for example, your Authorization header can be created from data contained in a Spring-Security Authorization object, then you can create a factory that sets the outgoing AuthorizationHeader on every request by doing SecurityContextHolder.getContext().getAuthorization() and then populating the header, with null checks as appropriate. Now all outbound rest calls made with that RestTemplate will have the correct Authorization header.

Without more emphasis placed on the HttpClientFactory mechanism, providing simple-to-overload base classes for common cases like adding a single header to requests, most of the nice convenience methods of RestTemplate end up being a waste of time, since they can only rarely be used.

I'd like to see something simple like this made available

@Configuration
public class MyConfig {
  @Bean
  public RestTemplate getRestTemplate() {
    return new RestTemplate(new AbstractHeaderRewritingHttpClientFactory() {
        @Override
        public HttpHeaders modifyHeaders(HttpHeaders headers) {
          headers.addHeader("Authorization", computeAuthString());
          return headers;
        }
        public String computeAuthString() {
          // do something better than this, but you get the idea
          return SecurityContextHolder.getContext().getAuthorization().getCredential();
        }
    });
  }
}

At the moment, the interface of the available ClientHttpRequestFactory's are harder to interact with than that. Even better would be an abstract wrapper for existing factory implementations which makes them look like a simpler object like AbstractHeaderRewritingRequestFactory for the purposes of replacing just that one piece of functionality. Right now, they are very general purpose such that even writing those wrappers is a complex piece of research.

You could remove the name attribute of this input, so it won't be submited.

To access the value of this controll:

$("div#someID").datepicker( "getDate" )

and your may have a look at the document in http://jqueryui.com/demos/datepicker/

Windows 10 Home Edition does not have Local Users and Groups option so that is the reason you aren't able to see that in Computer Management.

You can use User Accounts by pressing Window+R, typing netplwiz and pressing OK as described here.

from datetime import date

def calculate_age(born):
    today = date.today()
    try: 
        birthday = born.replace(year=today.year)
    except ValueError: # raised when birth date is February 29 and the current year is not a leap year
        birthday = born.replace(year=today.year, month=born.month+1, day=1)
    if birthday > today:
        return today.year - born.year - 1
    else:
        return today.year - born.year

Update: Use Danny's solution, it's better

I was encountering this error while compiling my application with SDL. This was caused by SDL defining it's own main function in SDL_main.h. To prevent SDL define the main function an SDL_MAIN_HANDLED macro has to be defined before the SDL.h header is included.

Use ByteArrayInputStream:

InputStream is = new ByteArrayInputStream(decodedBytes);

select name, games, goals
from tblMadrid where name = 'ronaldo'
union
select name, games, goals
from tblBarcelona where name = 'messi'
ORDER  BY goals 

For Kotlin and bindings the code is:

binding.spinner.onItemSelectedListener = object : AdapterView.OnItemSelectedListener{
            override fun onNothingSelected(parent: AdapterView<*>?) {
            }

            override fun onItemSelected(parent: AdapterView<*>?, view: View?, position: Int, id: Long) {
            }
        }

In case you're using ASP.NET 5 with ASP.NET MVC 6, most of these answers simply won't work because you'll normally let MVC create the appropriate route collection for you (using the default RESTful conventions), meaning that you won't find any Routes.MapRoute() call to edit at will.

The ConfigureServices() method invoked by the Startup.cs file will register MVC with the Dependency Injection framework built into ASP.NET 5: that way, when you call ApplicationBuilder.UseMvc() later in that class, the MVC framework will automatically add these default routes to your app. We can take a look of what happens behind the hood by looking at the UseMvc() method implementation within the framework source code:

public static IApplicationBuilder UseMvc(
    [NotNull] this IApplicationBuilder app,
    [NotNull] Action<IRouteBuilder> configureRoutes)
{
    // Verify if AddMvc was done before calling UseMvc
    // We use the MvcMarkerService to make sure if all the services were added.
    MvcServicesHelper.ThrowIfMvcNotRegistered(app.ApplicationServices);

    var routes = new RouteBuilder
    {
        DefaultHandler = new MvcRouteHandler(),
        ServiceProvider = app.ApplicationServices
    };

    configureRoutes(routes);

    // Adding the attribute route comes after running the user-code because
    // we want to respect any changes to the DefaultHandler.
    routes.Routes.Insert(0, AttributeRouting.CreateAttributeMegaRoute(
        routes.DefaultHandler,
        app.ApplicationServices));

    return app.UseRouter(routes.Build());
}

The good thing about this is that the framework now handles all the hard work, iterating through all the Controller's Actions and setting up their default routes, thus saving you some redundant work.

The bad thing is, there's little or no documentation about how you could add your own routes. Luckily enough, you can easily do that by using either a Convention-Based and/or an Attribute-Based approach (aka Attribute Routing).

Convention-Based

In your Startup.cs class, replace this:

app.UseMvc();

with this:

app.UseMvc(routes =>
            {
                // Route Sample A
                routes.MapRoute(
                    name: "RouteSampleA",
                    template: "MyOwnGet",
                    defaults: new { controller = "Items", action = "Get" }
                );
                // Route Sample B
                routes.MapRoute(
                    name: "RouteSampleB",
                    template: "MyOwnPost",
                    defaults: new { controller = "Items", action = "Post" }
                );
            });

Attribute-Based

A great thing about MVC6 is that you can also define routes on a per-controller basis by decorating either the Controller class and/or the Action methods with the appropriate RouteAttribute and/or HttpGet / HttpPost template parameters, such as the following:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using Microsoft.AspNet.Mvc;

namespace MyNamespace.Controllers
{
    [Route("api/[controller]")]
    public class ItemsController : Controller
    {
        // GET: api/items
        [HttpGet()]
        public IEnumerable<string> Get()
        {
            return GetLatestItems();
        }

        // GET: api/items/5
        [HttpGet("{num}")]
        public IEnumerable<string> Get(int num)
        {
            return GetLatestItems(5);
        }       

        // GET: api/items/GetLatestItems
        [HttpGet("GetLatestItems")]
        public IEnumerable<string> GetLatestItems()
        {
            return GetLatestItems(5);
        }

        // GET api/items/GetLatestItems/5
        [HttpGet("GetLatestItems/{num}")]
        public IEnumerable<string> GetLatestItems(int num)
        {
            return new string[] { "test", "test2" };
        }

        // POST: /api/items/PostSomething
        [HttpPost("PostSomething")]
        public IActionResult Post([FromBody]string someData)
        {
            return Content("OK, got it!");
        }
    }
}

This controller will handle the following requests:

 [GET] api/items
 [GET] api/items/5
 [GET] api/items/GetLatestItems
 [GET] api/items/GetLatestItems/5
 [POST] api/items/PostSomething

Also notice that if you use the two approaches togheter, Attribute-based routes (when defined) would override Convention-based ones, and both of them would override the default routes defined by UseMvc().

For more info, you can also read the following post on my blog.

Have you tried adding a magic comment in the script where you use non-ASCII chars? It should go on top of the script.

#!/bin/env ruby
# encoding: utf-8

It worked for me like a charm.

In Bash shell:

#!/bin/sh

COUNTER=1

while [ $COUNTER -lt 254 ]
do
   ping 192.168.1.$COUNTER -c 1
   COUNTER=$(( $COUNTER + 1 ))
done

If you want to search recursively, you can use this beautiful piece of code:

public static FileInfo GetNewestFile(DirectoryInfo directory) {
   return directory.GetFiles()
       .Union(directory.GetDirectories().Select(d => GetNewestFile(d)))
       .OrderByDescending(f => (f == null ? DateTime.MinValue : f.LastWriteTime))
       .FirstOrDefault();                        
}

Just call it the following way:

FileInfo newestFile = GetNewestFile(new DirectoryInfo(@"C:\directory\"));

and that's it. Returns a FileInfo instance or null if the directory is empty.

A simple way to do it is by using:

new Date().getTimezoneOffset();

This was already a month ago, but oh well.

I could be wrong, but for your question I get the feeling that bind_param isn't really the problem here. You always need to define some conditions, be it directly in the query string itself, of using bind_param to set the ? placeholders. That's not really an issue.

The problem I had using MySQLi SELECT * queries is the bind_result part. That's where it gets interesting. I came across this post from Jeffrey Way: http://jeff-way.com/2009/05/27/tricky-prepared-statements/(This link is no longer active). The script basically loops through the results and returns them as an array — no need to know how many columns there are, and you can still use prepared statements.

In this case it would look something like this:

$stmt = $mysqli->prepare(
  'SELECT * FROM tablename WHERE field1 = ? AND field2 = ?');
$stmt->bind_param('ss', $value, $value2);
$stmt->execute();

Then use the snippet from the site:

$meta = $stmt->result_metadata();

while ($field = $meta->fetch_field()) {
  $parameters[] = &$row[$field->name];
}

call_user_func_array(array($stmt, 'bind_result'), $parameters);

while ($stmt->fetch()) {
  foreach($row as $key => $val) {
    $x[$key] = $val;
  }
  $results[] = $x;
}

And $results now contains all the info from SELECT *. So far I found this to be an ideal solution.

This answer will be robust enough to work for elements that aren't on the page, therefore failing gracefully (not throwing an exception) if the selector failed to find the element.

const nameSelector = '[data-automation="name-input"]';
const nameInputIsDisplayed = () => {
    return $$(nameSelector).count()
        .then(count => count !== 0)
}
it('should be displayed', () => {
    nameInputIsDisplayed().then(isDisplayed => {
        expect(isDisplayed).toBeTruthy()
    })
})

Why don't you just do

for s in l :
    print s
print "done"

?

From the documentation:

__file__ is the pathname of the file from which the module was loaded, if it was loaded from a file. The __file__ attribute is not present for C modules that are statically linked into the interpreter; for extension modules loaded dynamically from a shared library, it is the pathname of the shared library file.

From the mailing list thread linked by @kindall in a comment to the question:

I haven't tried to repro this particular example, but the reason is that we don't want to have to call getpwd() on every import nor do we want to have some kind of in-process variable to cache the current directory. (getpwd() is relatively slow and can sometimes fail outright, and trying to cache it has a certain risk of being wrong.)

What we do instead, is code in site.py that walks over the elements of sys.path and turns them into absolute paths. However this code runs before '' is inserted in the front of sys.path, so that the initial value of sys.path is ''.

For the rest of this, consider sys.path not to include ''.

So, if you are outside the part of sys.path that contains the module, you'll get an absolute path. If you are inside the part of sys.path that contains the module, you'll get a relative path.

If you load a module in the current directory, and the current directory isn't in sys.path, you'll get an absolute path.

If you load a module in the current directory, and the current directory is in sys.path, you'll get a relative path.

There are lots of great answers which discuss differences in the use cases for each function. None of the answer discuss the differences in performance. That is reasonable cause various functions expects various input and produces various output, yet most of them have a general common objective to evaluate by series/groups. My answer is going to focus on performance. Due to above the input creation from the vectors is included in the timing, also the apply function is not measured.

I have tested two different functions sum and length at once. Volume tested is 50M on input and 50K on output. I have also included two currently popular packages which were not widely used at the time when question was asked, data.table and dplyr. Both are definitely worth to look if you are aiming for good performance.

library(dplyr)
library(data.table)
set.seed(123)
n = 5e7
k = 5e5
x = runif(n)
grp = sample(k, n, TRUE)

timing = list()

# sapply
timing[["sapply"]] = system.time({
    lt = split(x, grp)
    r.sapply = sapply(lt, function(x) list(sum(x), length(x)), simplify = FALSE)
})

# lapply
timing[["lapply"]] = system.time({
    lt = split(x, grp)
    r.lapply = lapply(lt, function(x) list(sum(x), length(x)))
})

# tapply
timing[["tapply"]] = system.time(
    r.tapply <- tapply(x, list(grp), function(x) list(sum(x), length(x)))
)

# by
timing[["by"]] = system.time(
    r.by <- by(x, list(grp), function(x) list(sum(x), length(x)), simplify = FALSE)
)

# aggregate
timing[["aggregate"]] = system.time(
    r.aggregate <- aggregate(x, list(grp), function(x) list(sum(x), length(x)), simplify = FALSE)
)

# dplyr
timing[["dplyr"]] = system.time({
    df = data_frame(x, grp)
    r.dplyr = summarise(group_by(df, grp), sum(x), n())
})

# data.table
timing[["data.table"]] = system.time({
    dt = setnames(setDT(list(x, grp)), c("x","grp"))
    r.data.table = dt[, .(sum(x), .N), grp]
})

# all output size match to group count
sapply(list(sapply=r.sapply, lapply=r.lapply, tapply=r.tapply, by=r.by, aggregate=r.aggregate, dplyr=r.dplyr, data.table=r.data.table), 
       function(x) (if(is.data.frame(x)) nrow else length)(x)==k)
#    sapply     lapply     tapply         by  aggregate      dplyr data.table 
#      TRUE       TRUE       TRUE       TRUE       TRUE       TRUE       TRUE 

# print timings
as.data.table(sapply(timing, `[[`, "elapsed"), keep.rownames = TRUE
              )[,.(fun = V1, elapsed = V2)
                ][order(-elapsed)]
#          fun elapsed
#1:  aggregate 109.139
#2:         by  25.738
#3:      dplyr  18.978
#4:     tapply  17.006
#5:     lapply  11.524
#6:     sapply  11.326
#7: data.table   2.686

If you want the branch too:

gem 'foo', path: "point/to/your/path", branch: "branch-name"

My reason for sometimes preferring Timer over Executors.newSingleThreadScheduledExecutor() is that I get much cleaner code when I need the timer to execute on daemon threads.

compare

private final ThreadFactory threadFactory = new ThreadFactory() {
    public Thread newThread(Runnable r) {
        Thread t = new Thread(r);
        t.setDaemon(true);
        return t;
    }
};
private final ScheduledExecutorService timer = Executors.newSingleThreadScheduledExecutor(threadFactory); 

with

private final Timer timer = new Timer(true);

I do this when I don't need the robustness of an executorservice.

Easy way ,but you need bootstrap

 <div class="input-group mb-3">
    <div class="input-group-prepend">
      <span class="input-group-text"><i class="fa fa-envelope"></i></span> <!-- icon envelope "class="fa fa-envelope""-->
    </div>
    <input type="email" id="senha_nova" placeholder="Email">
  </div><!-- input-group -->

window.onclick = e => {
    console.dir(e.target);  // use this in chrome
    console.log(e.target);  // use this in firefox - click on tag name to view 
}  

take advantage of using filter propeties

e.target.tagName
e.target.className
e.target.style.height  // its not the value applied from the css style sheet, to get that values use `getComputedStyle()`

With the assumption that there's only one element:

 $("#grid_GridHeader")[0]
 $("#grid_GridHeader").get(0)
 $("#grid_GridHeader").get()

...are all equivalent, returning the single underlying element.

From the jQuery source code, you can see that get(0), under the covers, essentially does the same thing as the [0] approach:

 // Return just the object
 ( num < 0 ? this.slice(num)[ 0 ] : this[ num ] );

It is, in principle, impossible to determine the encoding of a text file, in the general case. So no, there is no standard Python library to do that for you.

If you have more specific knowledge about the text file (e.g. that it is XML), there might be library functions.

var timestamp = DateTime.Now.ToFileTime();

//output: 132260149842749745

This is an alternative way to individuate distinct transactions. It's not unix time, but windows filetime.

From the docs:

A Windows file time is a 64-bit value that represents the number of 100- 
nanosecond intervals that have elapsed since 12:00 midnight, January 1, 1601 
A.D. (C.E.) Coordinated Universal Time (UTC).

You can directly use String.valueOf()

String.valueOf(charSequence)

Though this is same as toString() it does a null check on the charSequence before actually calling toString.

This is useful when a method can return either a charSequence or null value.

Simple! Throw this at the like, bottom of your CSS file and this part of the CSS will be modified within a phone: -

/* ON A PHONE */
@media only screen and (max-width: 600px) { /* CSS HERE ONLY ON PHONE */ }

And voila!

Something like

create or replace procedure my_proc( p_rc OUT SYS_REFCURSOR )
as
begin
  open p_rc
   for select 1 col1
         from dual;
end;
/

variable rc refcursor;
exec my_proc( :rc );
print rc;

will work in SQL*Plus or SQL Developer. I don't have any experience with Embarcardero Rapid XE2 so I have no idea whether it supports SQL*Plus commands like this.

Xcode 8.2.1 • Swift 3.0.2

There are a couple of mysql functions you need to look into.

• mysql_query("query string here") : returns a resource

• mysql_fetch_array(resource obtained above) : fetches a row and return as an array with numerical and associative(with column name as key) indices. Typically, you need to iterate through the results till expression evaluates to false value. Like the below:

  while ($row = mysql_fetch_array($query)){
      print_r $row;
  }

  Consult the manual, the links to which are provided below, they have more options to specify the format in which the array is requested. Like, you could use mysql_fetch_assoc(..) to get the row in an associative array.

Links:

• http://php.net/manual/en/function.mysql-query.php
• http://php.net/manual/en/function.mysql-fetch-array.php

In your case,

$query = "SELECT username,userid FROM user WHERE username = 'admin' ";
$result=mysql_query($query);
if (!$result){
    die("BAD!");
}
if (mysql_num_rows($result)==1){
    $row = mysql_fetch_array($result);
    echo "user Id: " . $row['userid'];
}
else{
    echo "not found!";
}

This is what worked for me. I am not sure why the syntax is different, But it was extremely frustrating trying every combination of activate, inactive, deactivated, disabled, etc. In lower case upper case in quotes out of quotes in brackets out of brackets etc. Well, here's the winning combination for me, for some reason.. different than everyone else?

import tkinter

class App(object):
    def __init__(self):
        self.tree = None
        self._setup_widgets()

    def _setup_widgets(self):
        butts = tkinter.Button(text = "add line", state="disabled")
        butts.grid()

def main():  
    root = tkinter.Tk()
    app = App()
    root.mainloop()

if __name__ == "__main__":
    main()

If possible I would try to write those test without Spring Context. If you create this class in your test without spring, then you have full control over its fields.

To set the @value field you can use Springs ReflectionTestUtils - it has a method setField to set private fields.

@see JavaDoc: ReflectionTestUtils.setField(java.lang.Object, java.lang.String, java.lang.Object)

This one works for me...

new System.Uri(Page.Request.Url, ResolveClientUrl("~/mypage.aspx")).AbsoluteUri

use this

when: "{{ 'value' in variable1}}"

instead of

when: "'value' in {{variable1}}"

Also for string comparison you can use

when: "{{ variable1 == 'value' }}"

That you can handle the checked and unchecked events seperately doesn't mean you have to. If you don't want to follow the MVVM pattern you can simply attach the same handler to both events and you have your change signal:

<CheckBox Checked="CheckBoxChanged" Unchecked="CheckBoxChanged"/>

and in Code-behind;

private void CheckBoxChanged(object sender, RoutedEventArgs e)
{
  MessageBox.Show("Eureka, it changed!");
}

Please note that WPF strongly encourages the MVVM pattern utilizing INotifyPropertyChanged and/or DependencyProperties for a reason. This is something that works, not something I would like to encourage as good programming habit.

It's been many functions, macros and objects since I posted this question. The way I handled it, which is mentioned in one of the answers here, is by creating a string function that handles the errors that get generate by the vlookup function, and returns either nothing or the vlookup result if any.

Function fsVlookup(ByVal pSearch As Range, ByVal pMatrix As Range, ByVal pMatColNum As Integer) As String
    Dim s As String
    On Error Resume Next
    s = Application.WorksheetFunction.VLookup(pSearch, pMatrix, pMatColNum, False)
    If IsError(s) Then
        fsVlookup = ""
    Else
        fsVlookup = s
    End If
End Function

One could argue about the position of the error handling or by shortening this code, but it works in all cases for me, and as they say, "if it ain't broke, don't try and fix it".

Intents are a way of telling Android what you want to do. In other words, you describe your intention. Intents can be used to signal to the Android system that a certain event has occurred. Other components in Android can register to this event via an intent filter.

Following are 2 types of intents

1.Explicit Intents

used to call a specific component. When you know which component you want to launch and you do not want to give the user free control over which component to use. For example, you have an application that has 2 activities. Activity A and activity B. You want to launch activity B from activity A. In this case you define an explicit intent targeting activityB and then use it to directly call it.

2.Implicit Intents

used when you have an idea of what you want to do, but you do not know which component should be launched. Or if you want to give the user an option to choose between a list of components to use. If these Intents are send to the Android system it searches for all components which are registered for the specific action and the data type. If only one component is found, Android starts the component directly. For example, you have an application that uses the camera to take photos. One of the features of your application is that you give the user the possibility to send the photos he has taken. You do not know what kind of application the user has that can send photos, and you also want to give the user an option to choose which external application to use if he has more than one. In this case you would not use an explicit intent. Instead you should use an implicit intent that has its action set to ACTION_SEND and its data extra set to the URI of the photo.

An explicit intent is always delivered to its target, no matter what it contains; the filter is not consulted. But an implicit intent is delivered to a component only if it can pass through one of the component's filters

Intent Filters

If an Intents is send to the Android system, it will determine suitable applications for this Intents. If several components have been registered for this type of Intents, Android offers the user the choice to open one of them.

This determination is based on IntentFilters. An IntentFilters specifies the types of Intent that an activity, service, orBroadcast Receiver can respond to. An Intent Filter declares the capabilities of a component. It specifies what anactivity or service can do and what types of broadcasts a Receiver can handle. It allows the corresponding component to receive Intents of the declared type. IntentFilters are typically defined via the AndroidManifest.xml file. For BroadcastReceiver it is also possible to define them in coding. An IntentFilters is defined by its category, action and data filters. It can also contain additional metadata.

If a component does not define an Intent filter, it can only be called by explicit Intents.

Following are 2 ways to define a filter

1.Manifest file

If you define the intent filter in the manifest, your application does not have to be running to react to the intents defined in it’s filter. Android registers the filter when your application gets installed.

2.BroadCast Receiver

If you want your broadcast receiver to receive the intent only when your application is running. Then you should define your intent filter during run time (programatically). Keep in mind that this works for broadcast receivers only.

As mentioned array.find() is not supported in IE.

However you can read about a Polyfill here:

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/find#Polyfill

This method has been added to the ECMAScript 2015 specification and may not be available in all JavaScript implementations yet. However, you can polyfill Array.prototype.find with the following snippet:

Code:

// https://tc39.github.io/ecma262/#sec-array.prototype.find
if (!Array.prototype.find) {
  Object.defineProperty(Array.prototype, 'find', {
    value: function(predicate) {
     // 1. Let O be ? ToObject(this value).
      if (this == null) {
        throw new TypeError('"this" is null or not defined');
      }

      var o = Object(this);

      // 2. Let len be ? ToLength(? Get(O, "length")).
      var len = o.length >>> 0;

      // 3. If IsCallable(predicate) is false, throw a TypeError exception.
      if (typeof predicate !== 'function') {
        throw new TypeError('predicate must be a function');
      }

      // 4. If thisArg was supplied, let T be thisArg; else let T be undefined.
      var thisArg = arguments[1];

      // 5. Let k be 0.
      var k = 0;

      // 6. Repeat, while k < len
      while (k < len) {
        // a. Let Pk be ! ToString(k).
        // b. Let kValue be ? Get(O, Pk).
        // c. Let testResult be ToBoolean(? Call(predicate, T, « kValue, k, O »)).
        // d. If testResult is true, return kValue.
        var kValue = o[k];
        if (predicate.call(thisArg, kValue, k, o)) {
          return kValue;
        }
        // e. Increase k by 1.
        k++;
      }

      // 7. Return undefined.
      return undefined;
    }
  });
}

The Active Record definitely has some quirks. When you pass an array to the $this->db->where() function it will generate an IS NULL. For example:

$this->db->where(array('archived' => NULL));

produces

WHERE `archived` IS NULL 

The quirk is that there is no equivalent for the negative IS NOT NULL. There is, however, a way to do it that produces the correct result and still escapes the statement:

$this->db->where('archived IS NOT NULL');

produces

WHERE `archived` IS NOT NULL

I spent half a day with this problem. The reason was that be sure to check where the volume was recorded.

volumes: - api-data:/src/patterns

But the fact is that in this place was the code that we changed. But when updating the docker, the code did not change.

Therefore, if you are checking someone else's code and for some reason you are not updating, check this.

And so in general this approach works:

docker-compose down

docker-compose build

docker-compose up -d

There are two ways to connect remote redis server using redis-cli:

1. Using host & port individually as options in command

redis-cli -h host -p port

If your instance is password protected

redis-cli -h host -p port -a password

e.g. if my-web.cache.amazonaws.com is the host url and 6379 is the port

Then this will be the command:

redis-cli -h my-web.cache.amazonaws.com -p 6379

if 92.101.91.8 is the host IP address and 6379 is the port:

redis-cli -h 92.101.91.8 -p 6379

command if the instance is protected with password pass123:

redis-cli -h my-web.cache.amazonaws.com -p 6379 -a pass123

2. Using single uri option in command

redis-cli -u redis://password@host:port

command in a single uri form with username & password

redis-cli -u redis://username:password@host:port

e.g. for the same above host - port configuration command would be

redis-cli -u redis://[email protected]:6379

command if username is also provided user123

redis-cli -u redis://user123:[email protected]:6379

This detailed answer was for those who wants to check all options. For more information check documentation: Redis command line usage

This is a mistake:

m.check(side);

That code has to go inside a function. Your class definition can only contain declarations and functions.

Classes don't "run", they provide a blueprint for how to make an object.

The line Message m; means that an Orderbook will contain Message called m, if you later create an Orderbook.

@Html.DropdownListFor(model=model->Gender,new List<SelectListItem>
{
 new ListItem{Text="Male",Value="Male"},
 new ListItem{Text="Female",Value="Female"},
 new ListItem{Text="--- Select -----",Value="-----Select ----"}
}
)

On my FreeBSD system, stat just returns a bless.

$VAR1 = bless( [
                 102,
                 8,
                 33188,
                 1,
                 0,
                 0,
                 661,
                 276,
                 1372816636,
                 1372755222,
                 1372755233,
                 32768,
                 8
               ], 'File::stat' );

You need to extract mtime like this:

my @ABC = (stat($my_file));

print "-----------$ABC['File::stat'][9] ------------------------\n";

or

print "-----------$ABC[0][9] ------------------------\n";

select  stuff(list,1,1,'')
from    (
        select  ',' + cast(col1 as varchar(16)) as [text()]
        from    YourTable
        for     xml path('')
        ) as Sub(list)

Example at SQL Fiddle.

I would use itertools.chain - this will also cater for > 1 element in each sublist:

from itertools import chain
list(chain.from_iterable([[180.0], [173.8], [164.2], [156.5], [147.2], [138.2]]))

Another great implementation is jQuery History which will use the native onhashchange event if it is supported by the browser, if not it will use an iframe or interval appropriately for the browser to ensure all the expected functionality is successfully emulated. It also provides a nice interface to bind to certain states.

Another project worth noting as well is jQuery Ajaxy which is pretty much an extension for jQuery History to add ajax to the mix. As when you start using ajax with hashes it get's quite complicated!

As mentioned here - https://kite.com/python/answers/how-to-append-a-list-as-a-row-to-a-pandas-dataframe-in-python, you'll need to first convert the list to a series then append the series to dataframe.

df = pd.DataFrame([[1, 2], [3, 4]], columns = ["a", "b"])
to_append = [5, 6]
a_series = pd.Series(to_append, index = df.columns)
df = df.append(a_series, ignore_index=True)

MailSystem.NET contains all your need for IMAP4. It's free & open source.

(I'm involved in the project)

Due to the disadvantages described below, I would recommend following the accepted answer:

Use npm install --save-dev [package_name] then execute scripts with:

$ npm run lint
$ npm run build
$ npm test

My original but not recommended answer follows.

Instead of using a global install, you could add the package to your devDependencies (--save-dev) and then run the binary from anywhere inside your project:

"$(npm bin)/<executable_name>" <arguments>...

In your case:

"$(npm bin)"/node.io --help

This engineer provided an npm-exec alias as a shortcut. This engineer uses a shellscript called env.sh. But I prefer to use $(npm bin) directly, to avoid any extra file or setup.

Although it makes each call a little larger, it should just work, preventing:

• potential dependency conflicts with global packages (@nalply)
• the need for sudo
• the need to set up an npm prefix (although I recommend using one anyway)

Disadvantages:

• $(npm bin) won't work on Windows.
• Tools deeper in your dev tree will not appear in the npm bin folder. (Install npm-run or npm-which to find them.)

It seems a better solution is to place common tasks (such as building and minifying) in the "scripts" section of your package.json, as Jason demonstrates above.

I was able to get this working using the answer found here:

How to git commit nothing without an error?

git diff --quiet --exit-code --cached || git commit -m 'bla'

This will return what you asked, but I wouldnt recommend using css like this. Use external CSS instead of inline css.

$("tr[id='pDetails']").attr("style").split(':')[1];

Instead of just doing this quoted method from https://stackoverflow.com/a/4635440/3787376,

You can do something like this:

// show loading image
$('#loader_img').show();

// main image loaded ?
$('#main_img').on('load', function(){
  // hide/remove the loading image
  $('#loader_img').hide();
});

You assign load event to the image which fires when image has finished loading. Before that, you can show your loader image.

you can use a different jQuery function to make the loading image fade away, then be hidden:

// Show the loading image.
$('#loader_img').show();

// When main image loads:
$('#main_img').on('load', function(){
  // Fade out and hide the loading image.
  $('#loader_img').fadeOut(100); // Time in milliseconds.
});

"Once the opacity reaches 0, the display style property is set to none." http://api.jquery.com/fadeOut/

Or you could not use the jQuery library because there are already simple cross-browser JavaScript methods.

Google allows you to search in the project, but not the code :(

site:https://github.com/CreateJS/EaselJS test

I believe what you are looking for is functional approach

    const arr = ['a', 'a', 'b', 'g', 'a', 'e'];
    const count = arr.filter(elem => elem === 'a').length;
    console.log(count); // Prints 3

elem === 'a' is the condition, replace it with your own.

Try:

if (isset($_FILES['uploaded_file']) &&
    $_FILES['uploaded_file']['error'] == UPLOAD_ERR_OK) {
    $mail->AddAttachment($_FILES['uploaded_file']['tmp_name'],
                         $_FILES['uploaded_file']['name']);
}

Basic example can also be found here.

The function definition for AddAttachment is:

public function AddAttachment($path,
                              $name = '',
                              $encoding = 'base64',
                              $type = 'application/octet-stream')

Use the in keyword.

if 'apples' in d:
    if d['apples'] == 20:
        print('20 apples')
    else:
        print('Not 20 apples')

If you want to get the value only if the key exists (and avoid an exception trying to get it if it doesn't), then you can use the get function from a dictionary, passing an optional default value as the second argument (if you don't pass it it returns None instead):

if d.get('apples', 0) == 20:
    print('20 apples.')
else:
    print('Not 20 apples.')

I had to allow adb.exe to access my network in my firewall.

You can also use the following attr thing;

HTML

<div id="mydiv" data-myval="JohnCena"></div>

Script

 $('#mydiv').attr('data-myval', 'Undertaker'); // sets 
 $('#mydiv').attr('data-myval'); // gets

OR

$('#mydiv').data('myval'); // gets value
$('#mydiv').data('myval','John Cena'); // sets value

Check out from dateutil.relativedelta import * for adding a specific amount of time to a date, you can continue to use timedelta for the simple stuff i.e.

use_date = use_date + datetime.timedelta(minutes=+10)
use_date = use_date + datetime.timedelta(hours=+1)
use_date = use_date + datetime.timedelta(days=+1)
use_date = use_date + datetime.timedelta(weeks=+1)

or you can start using relativedelta

use_date = use_date+relativedelta(months=+1)

use_date = use_date+relativedelta(years=+1)

for the last day of next month:

use_date = use_date+relativedelta(months=+1)
use_date = use_date+relativedelta(day=31)

Right now this will provide 29/02/2016

for the penultimate day of next month:

use_date = use_date+relativedelta(months=+1)
use_date = use_date+relativedelta(day=31)
use_date = use_date+relativedelta(days=-1)

last Friday of the next month:

use_date = use_date+relativedelta(months=+1, day=31, weekday=FR(-1))

2nd Tuesday of next month:

new_date = use_date+relativedelta(months=+1, day=1, weekday=TU(2))

As @mrroot5 points out dateutil's rrule functions can be applied, giving you an extra bang for your buck, if you require date occurences.
for example:
Calculating the last day of the month for 9 months from the last day of last month.
Then, calculate the 2nd Tuesday for each of those months.

from dateutil.relativedelta import *
from dateutil.rrule import *
from datetime import datetime
use_date = datetime(2020,11,21)

#Calculate the last day of last month
use_date = use_date+relativedelta(months=-1)
use_date = use_date+relativedelta(day=31)

#Generate a list of the last day for 9 months from the calculated date
x = list(rrule(freq=MONTHLY, count=9, dtstart=use_date, bymonthday=(-1,)))
print("Last day")
for ld in x:
    print(ld)

#Generate a list of the 2nd Tuesday in each of the next 9 months from the calculated date
print("\n2nd Tuesday")
x = list(rrule(freq=MONTHLY, count=9, dtstart=use_date, byweekday=TU(2)))
for tuesday in x:
    print(tuesday)

ax.title.set_text('My Plot Title') seems to work too.

ax3 = fig.add_subplot(223)
ax4 = fig.add_subplot(224)

I was facing similar problems trying to do some dat import on an intermediate schema (that later we move on to the final one). As we rely on things like extensions (for example PostGIS), the "run_insert" sql file did not fully solved the problem.

After a while, we've found that at least with Postgres 9.3 the solution is far easier... just create your SQL script always specifying the schema when refering to the table:

CREATE TABLE "my_schema"."my_table" (...); COPY "my_schema"."my_table" (...) FROM stdin;

This way using psql -f xxxxx works perfectly, and you don't need to change search_paths nor use intermediate files (and won't hit extension schema problems).

This should work

render(){_x000D_
_x000D_
 var payments = [];_x000D_
_x000D_
 for(let i = 0; i < noGuest; i++){_x000D_
_x000D_
  payments.push(_x000D_
   <View key = {i}>_x000D_
    <View>_x000D_
     <TextInput />_x000D_
    </View>_x000D_
    <View>_x000D_
     <TextInput />_x000D_
    </View>_x000D_
    <View>_x000D_
     <TextInput />_x000D_
    </View>_x000D_
   </View>_x000D_
  )_x000D_
 }_x000D_
 _x000D_
 return (_x000D_
  <View>_x000D_
   <View>_x000D_
    <View><Text>No</Text></View>_x000D_

_x000D_
   { payments }_x000D_
  </View>_x000D_
 )_x000D_
}

Just use

git checkout filename

This will replace filename with the latest version from the current branch.

Ive come across this many times in my work, an easy work around that I found is to ask if the array element is a Hash by class.

if i.class == Hash

    notation like i[:label] will work in this block and not throw that error

end

You can also just return string if you know that's the only thing the method will ever return. For example:

public string MyActionName() {
  return "Hi there!";
}

As i know, you can't do it in a sentence.

But you can build an stored procedure that do the deletes you want in whatever table in a transaction, what is almost the same.

For MySQL, please find the below query:

select * from (select PartID, max(Pricedate) max_pricedate from MyPrices group bu partid) as a 
    inner join MyParts b on
    (a.partid = b.partid and a.max_pricedate = b.pricedate)

Inside the subquery it fetches max pricedate for every partyid of MyPrices then, inner joining with MyParts using partid and the max_pricedate

What about an answer for the question related to a workflow like this?

1. many local commits, mixed with multiple merges FROM master,
2. finally a push to remote,
3. PR and merge TO master by reviewer. (Yes, it would be easier for the developer to merge --squash after the PR, but the team thought that would slow down the process.)

I haven't seen a workflow like that on this page. (That may be my eyes.) If I understand rebase correctly, multiple merges would require multiple conflict resolutions. I do NOT want even to think about that!

So, this seems to work for us.

1. git pull master
2. git checkout -b new-branch
3. git checkout -b new-branch-temp
4. edit and commit a lot locally, merge master regularly
5. git checkout new-branch
6. git merge --squash new-branch-temp // puts all changes in stage
7. git commit 'one message to rule them all'
8. git push
9. Reviewer does PR and merges to master.

Unless you're running a production server, don't worry about this message. This is a library which is used to improve performance (on production systems). From Apache Portable Runtime (APR) based Native library for Tomcat:

Tomcat can use the Apache Portable Runtime to provide superior scalability, performance, and better integration with native server technologies. The Apache Portable Runtime is a highly portable library that is at the heart of Apache HTTP Server 2.x. APR has many uses, including access to advanced IO functionality (such as sendfile, epoll and OpenSSL), OS level functionality (random number generation, system status, etc), and native process handling (shared memory, NT pipes and Unix sockets).

It means that the number of values specified in your VALUES clause on the INSERT statement is not equal to the total number of columns in the table. You must specify the columnname if you only try to insert on selected columns.

Another one, since you are using ADO.Net , always parameterized your query to avoid SQL Injection. What you are doing right now is you are defeating the use of sqlCommand.

ex

Dim query as String = String.Empty
query &= "INSERT INTO student (colName, colID, colPhone, "
query &= "                     colBranch, colCourse, coldblFee)  "
query &= "VALUES (@colName,@colID, @colPhone, @colBranch,@colCourse, @coldblFee)"

Using conn as New SqlConnection("connectionStringHere")
    Using comm As New SqlCommand()
        With comm
            .Connection = conn
            .CommandType = CommandType.Text
            .CommandText = query
            .Parameters.AddWithValue("@colName", strName)
            .Parameters.AddWithValue("@colID", strId)
            .Parameters.AddWithValue("@colPhone", strPhone)
            .Parameters.AddWithValue("@colBranch", strBranch)
            .Parameters.AddWithValue("@colCourse", strCourse)
            .Parameters.AddWithValue("@coldblFee", dblFee)
        End With
        Try
            conn.open()
            comm.ExecuteNonQuery()
        Catch(ex as SqlException)
            MessageBox.Show(ex.Message.ToString(), "Error Message")
        End Try
    End Using
End USing 

PS: Please change the column names specified in the query to the original column found in your table.

For completely transparent color, use:

rbga(255,255,255,0)

A little more visible:

rbga(255,255,255,.3)

Use checked to get the value. During onChange, checked will be true and it will be a type of boolean.

Hope this helps!

From their signature generator, you can generate curl commands of the form:

curl --get 'https://api.twitter.com/1.1/statuses/user_timeline.json' --data 'count=2&screen_name=twitterapi' --header 'Authorization: OAuth oauth_consumer_key="YOUR_KEY", oauth_nonce="YOUR_NONCE", oauth_signature="YOUR-SIG", oauth_signature_method="HMAC-SHA1", oauth_timestamp="TIMESTAMP", oauth_token="YOUR-TOKEN", oauth_version="1.0"' --verbose

I'm not entirely sure but I think you are probably surprised at how arrays are serialized in JSON. Let's isolate the problem. Consider following code:

var display = Array();
display[0] = "none";
display[1] = "block";
display[2] = "none";

console.log( JSON.stringify(display) );

This will print:

["none","block","none"]

This is how JSON actually serializes array. However what you want to see is something like:

{"0":"none","1":"block","2":"none"}

To get this format you want to serialize object, not array. So let's rewrite above code like this:

var display2 = {};
display2["0"] = "none";
display2["1"] = "block";
display2["2"] = "none";

console.log( JSON.stringify(display2) );

This will print in the format you want.

You can play around with this here: http://jsbin.com/oDuhINAG/1/edit?js,console

A technique I use is something like the following. Define a global variable that you can use for one or multiple try catch blocks depending on what you're trying to debug and use the following structure:

if(!GlobalTestingBool)
{
   try
   {
      SomeErrorProneMethod();
   }
   catch (...)
   {
      // ... Error handling ...
   }
}
else
{
   SomeErrorProneMethod();
}

I find this gives me a bit more flexibility in terms of testing because there are still some exceptions I don't want the IDE to break on.

from the FAQ

elem = $("#elemid");
if (elem.is (".class")) {
   // whatever
}

or:

elem = $("#elemid");
if (elem.hasClass ("class")) {
   // whatever
}

NGINX supports WebSockets by allowing a tunnel to be setup between a client and a backend server. In order for NGINX to send the Upgrade request from the client to the backend server, Upgrade and Connection headers must be set explicitly. For example:

# WebSocket proxying
map $http_upgrade $connection_upgrade {
    default         upgrade;
    ''              close;
}


server {
    listen 80;

    # The host name to respond to
    server_name cdn.domain.com;

    location / {
        # Backend nodejs server
        proxy_pass          http://127.0.0.1:8080;
        proxy_http_version  1.1;
        proxy_set_header    Upgrade     $http_upgrade;
        proxy_set_header    Connection  $connection_upgrade;
    }
}

If the object was recently created, you can check the Schema Changes History report, within the SQL Server Management Studio, which "provides a history of all committed DDL statement executions within the Database recorded by the default trace":

You then can search for the create statements of the objects. Among all the information displayed, there is the login name of whom executed the DDL statement.

Apparently you don't need to specify height at all! Which is great if it changes for some reason (you resize components or change font sizes).

I just followed this tutorial and everything worked: http://natashatherobot.com/ios-autolayout-scrollview/

(Side note: There is no need to implement viewDidLayoutSubviews unless you want to center the view, so the list of steps is even shorter).

Hope that helps!

Print the Upper and Lower case alphabets in python using a built-in range function

def upperCaseAlphabets():
    print("Upper Case Alphabets")
    for i in range(65, 91):
        print(chr(i), end=" ")
    print()

def lowerCaseAlphabets():
    print("Lower Case Alphabets")
    for i in range(97, 123):
        print(chr(i), end=" ")

upperCaseAlphabets();
lowerCaseAlphabets();

Here's one that doesn't assume the input is a string, uses substring, and comes with a couple of unit tests:

var cutOutZero = function(value) {
    if (value.length && value.length > 0 && value[0] === '0') {
        return value.substring(1);
    }

    return value;
};

With new feature in docker option --config, you needn't set Proxy in Dockerfile any more. You can have same Dockerfile to be used in and out corporate environment.

--config string      Location of client config files (default "~/.docker")

or environment variable DOCKER_CONFIG

`DOCKER_CONFIG` The location of your client configuration files.

$ export DOCKER_CONFIG=~/.docker

https://docs.docker.com/engine/reference/commandline/cli/

https://docs.docker.com/network/proxy/

I recommend to set proxy with httpProxy, httpsProxy, ftpProxy and noProxy (The official document misses the variable ftpProxy which is useful sometimes)

{
 "proxies":
 {
   "default":
   {
     "httpProxy": "http://127.0.0.1:3001",
     "httpsProxy": "http://127.0.0.1:3001",
     "ftpProxy": "http://127.0.0.1:3001",
     "noProxy": "*.test.example.com,.example2.com"
   }
 }
}

Adjust proxy IP and port if needed and save to ~/.docker/config.json

After yo set properly with it, you can run docker build and docker run as normal.

$ docker build -t demo . 

$ docker run -ti --rm demo env|grep -ri proxy
(standard input):http_proxy=http://127.0.0.1:3001
(standard input):HTTPS_PROXY=http://127.0.0.1:3001
(standard input):https_proxy=http://127.0.0.1:3001
(standard input):NO_PROXY=*.test.example.com,.example2.com
(standard input):no_proxy=*.test.example.com,.example2.com
(standard input):FTP_PROXY=http://127.0.0.1:3001
(standard input):ftp_proxy=http://127.0.0.1:3001
(standard input):HTTP_PROXY=http://127.0.0.1:3001

Old answer (Decommissioned)

Below setting in Dockerfile works for me. I tested in CoreOS, Vagrant and boot2docker. Suppose the proxy port is 3128

In Centos:

ENV http_proxy=ip:3128 
ENV https_proxy=ip:3128

In Ubuntu:

ENV http_proxy 'http://ip:3128'
ENV https_proxy 'http://ip:3128'

Be careful of the format, some have http in it, some haven't, some with single quota. if the IP address is 192.168.0.193, then the setting will be:

In Centos:

ENV http_proxy=192.168.0.193:3128 
ENV https_proxy=192.168.0.193:3128

In Ubuntu:

ENV http_proxy 'http://192.168.0.193:3128'
ENV https_proxy 'http://192.168.0.193:3128'

If you need set proxy in coreos, for example to pull the image

cat /etc/systemd/system/docker.service.d/http-proxy.conf

[Service]
Environment="HTTP_PROXY=http://192.168.0.193:3128"

First add next code in your sp:

BEGIN
    dbms_output.enable();
    dbms_output.put_line ('TEST LINE'); 
END;

Compile your code in your Oracle SQL developer. So go to Menu View--> dbms output. Click on Icon Green Plus and select your schema. Run your sp now.

See the following sample code on how to Build a basic Keras Neural Net Model, save Model (JSON) & Weights (HDF5) and load them:

# create model
model = Sequential()
model.add(Dense(X.shape[1], input_dim=X.shape[1], activation='relu')) #Input Layer
model.add(Dense(X.shape[1], activation='relu')) #Hidden Layer
model.add(Dense(output_dim, activation='softmax')) #Output Layer

# Compile & Fit model
model.compile(loss='binary_crossentropy', optimizer='adam', metrics=['accuracy'])
model.fit(X,Y,nb_epoch=5,batch_size=100,verbose=1)    

# serialize model to JSON
model_json = model.to_json()
with open("Data/model.json", "w") as json_file:
    json_file.write(simplejson.dumps(simplejson.loads(model_json), indent=4))

# serialize weights to HDF5
model.save_weights("Data/model.h5")
print("Saved model to disk")

# load json and create model
json_file = open('Data/model.json', 'r')
loaded_model_json = json_file.read()
json_file.close()
loaded_model = model_from_json(loaded_model_json)

# load weights into new model
loaded_model.load_weights("Data/model.h5")
print("Loaded model from disk")

# evaluate loaded model on test data 
# Define X_test & Y_test data first
loaded_model.compile(loss='binary_crossentropy', optimizer='adam', metrics=['accuracy'])
score = loaded_model.evaluate(X_test, Y_test, verbose=0)
print ("%s: %.2f%%" % (loaded_model.metrics_names[1], score[1]*100))

You can make it a KeyValuePair, so it will return a "IEnumerable<KeyValuePair<string, string>>"

So, it will be like this:

.Select(i => new KeyValuePair<string, string>(i.category_id, i.category_name )).Distinct();

It's simple enough when you find out.

Open /etc/hosts (unix) or C:\WINDOWS\system32\drivers\etc\hosts.

If your domain is foo.com, then add this line:

127.0.0.1    local.foo.com

When you are testing, open local.foo.com in your browser and it should work.

simply use a 'script' tag with a dot after.

script.
  var users = !{JSON.stringify(users).replace(/<\//g, "<\\/")}

https://github.com/pugjs/pug/blob/master/examples/dynamicscript.pug

For me this works perfect

insert into oehr.employees select * from employees where employee_id=99

I am not sure why you get error. The nature of the error code you have produced is the columns didn't match.

One good approach will be to use the answer @Parodo specified

In the first instance you are trying to create what is called a jagged array.

double[][] ServicePoint = new double[10][9].

The above statement would have worked if it was defined like below.

double[][] ServicePoint = new double[10][]

what this means is you are creating an array of size 10 ,that can store 10 differently sized arrays inside it.In simple terms an Array of arrays.see the below image,which signifies a jagged array.

http://msdn.microsoft.com/en-us/library/2s05feca(v=vs.80).aspx

The second one is basically a two dimensional array and the syntax is correct and acceptable.

  double[,] ServicePoint = new double[10,9];//<-ok (2)

And to access or modify a two dimensional array you have to pass both the dimensions,but in your case you are passing just a single dimension,thats why the error

Correct usage would be

ServicePoint[0][2] ,Refers to an item on the first row ,third column.

Pictorial rep of your two dimensional array

A NULL pointer points to memory that doesn't exist, and will raise Segmentation fault. There's an easier way to de-reference a NULL pointer, take a look.

int main(int argc, char const *argv[])
{
    *(int *)0 = 0; // Segmentation fault (core dumped)
    return 0;
}

Since 0 is never a valid pointer value, a fault occurs.

SIGSEGV {si_signo=SIGSEGV, si_code=SEGV_MAPERR, si_addr=NULL}

Check next lines in you app build.gradle file.

android {
    compileSdkVersion 25       <--- Set exist in local machine sdk version.
    buildToolsVersion '25.0.3' <--- Set exist build tools version.
}

Centos 7 with PHP7.2:

sudo yum --enablerepo=remi-php72 install php-pecl-zip

driver.find_element_by_id("some_id").size() is class method.

What we need is :

driver.find_element_by_id("some_id").size which is dictionary so :

if driver.find_element_by_id("some_id").size['width'] != 0 : print 'button exist'

insert into TABLE_NAME
(COL1,COL2)
WITH
data AS
(
    select 'some value'    x from dual
    union all
    select 'another value' x from dual
)
SELECT my_seq.NEXTVAL, x 
FROM data
;

I think that is what you want, but i don't have access to oracle to test it right now.

git rev-parse --show-toplevel

could be enough if executed within a git repo.
From git rev-parse man page:

--show-toplevel

Show the absolute path of the top-level directory.

For older versions (before 1.7.x), the other options are listed in "Is there a way to get the git root directory in one command?":

git rev-parse --git-dir

That would give the path of the .git directory.

The OP mentions:

git rev-parse --show-prefix

which returns the local path under the git repo root. (empty if you are at the git repo root)

Note: for simply checking if one is in a git repo, I find the following command quite expressive:

git rev-parse --is-inside-work-tree

And yes, if you need to check if you are in a .git git-dir folder:

git rev-parse --is-inside-git-dir

SELECT id FROM tbl GROUP BY cat HAVING MAX(date)

For anyone that is working with a directory style like this:

project
    > src
        > pkgA     
        > pkgB
        ...
    > bin
        > pkgA
        > pkgB
        ...

The following worked very well for me. I made this myself, using the GNU make manual as my main reference; this, in particular, was extremely helpful for my last rule, which ended up being the most important one for me.

My Makefile:

PROG := sim
CC := g++
ODIR := bin
SDIR := src
MAIN_OBJ := main.o
MAIN := main.cpp
PKG_DIRS := $(shell ls $(SDIR))
CXXFLAGS = -std=c++11 -Wall $(addprefix -I$(SDIR)/,$(PKG_DIRS)) -I$(BOOST_ROOT)
FIND_SRC_FILES = $(wildcard $(SDIR)/$(pkg)/*.cpp) 
SRC_FILES = $(foreach pkg,$(PKG_DIRS),$(FIND_SRC_FILES)) 
OBJ_FILES = $(patsubst $(SDIR)/%,$(ODIR)/%,\
$(patsubst %.cpp,%.o,$(filter-out $(SDIR)/main/$(MAIN),$(SRC_FILES))))

vpath %.h $(addprefix $(SDIR)/,$(PKG_DIRS))
vpath %.cpp $(addprefix $(SDIR)/,$(PKG_DIRS)) 
vpath $(MAIN) $(addprefix $(SDIR)/,main)

# main target
#$(PROG) : all
$(PROG) : $(MAIN) $(OBJ_FILES) 
    $(CC) $(CXXFLAGS) -o $(PROG) $(SDIR)/main/$(MAIN) 

# debugging
all : ; $(info $$PKG_DIRS is [${PKG_DIRS}])@echo Hello world

%.o : %.cpp
    $(CC) $(CXXFLAGS) -c $< -o $@

# This one right here, folks. This is the one.
$(OBJ_FILES) : $(ODIR)/%.o : $(SDIR)/%.h
    $(CC) $(CXXFLAGS) -c $< -o $@

# for whatever reason, clean is not being called...
# any ideas why???
.PHONY: clean

clean :
    @echo Build done! Cleaning object files...
    @rm -r $(ODIR)/*/*.o

By using $(SDIR)/%.h as a prerequisite for $(ODIR)/%.o, this forced make to look in source-package directories for source code instead of looking in the same folder as the object file.

I hope this helps some people. Let me know if you see anything wrong with what I've provided.

BTW: As you may see from my last comment, clean is not being called and I am not sure why. Any ideas?

None of the existing answers quite offers a simple solution that returns "the number of rows that are just duplicates and should be cut out". This is a one-size-fits-all solution that does:

# generate a table of those culprit rows which are duplicated:
dups = df.groupby(df.columns.tolist()).size().reset_index().rename(columns={0:'count'})

# sum the final col of that table, and subtract the number of culprits:
dups['count'].sum() - dups.shape[0]

I got this solution. Does this help you ?

You can emulate it like this:

  countDownLatch = {
     count: 0,
     check: function() {
         this.count--;
         if (this.count == 0) this.calculate();
     },
     calculate: function() {...}
  };

then each async call does this:

countDownLatch.count++;

while in each asynch call back at the end of the method you add this line:

countDownLatch.check();

In other words, you emulate a count-down-latch functionality.

<!-- its Expression Language -->

I've used this solution to get what you need.

Let'say that in my .aspx code there's a select list runat="server":

<select id="testSelect"  runat="server" ClientIDMode="Static" required>
    <option value="1">One</option>
    <option value="2">Two</option>
</select>

In my C# code I used the code below to retrieve the text and also value of the options:

testSelect.SelectedIndex == 0 ? "uninformed" : 
    testSelect.Items[testSelect.SelectedIndex].Text);

In this case I check if the user selected any of the options. If there's nothing selected I show the text as "uninformed".

Just paste the below formula in any of the cells, it will render the path of the file:

=LEFT(CELL("filename"),FIND("]",CELL("filename"),1))

The above formula works in any version of Excel.

Combining answers from @owencm and @Chazt3n, this function will allow download of text from IE11, Firefox, and Chrome. (Sorry, I don't have access to Safari or Opera, but please add a comment if you try and it works.)

initiate_user_download = function(file_name, mime_type, text) {
    // Anything but IE works here
    if (undefined === window.navigator.msSaveOrOpenBlob) {
        var e = document.createElement('a');
        var href = 'data:' + mime_type + ';charset=utf-8,' + encodeURIComponent(text);
        e.setAttribute('href', href);
        e.setAttribute('download', file_name);
        document.body.appendChild(e);
        e.click();
        document.body.removeChild(e);
    }
    // IE-specific code
    else {
        var charCodeArr = new Array(text.length);
        for (var i = 0; i < text.length; ++i) {
            var charCode = text.charCodeAt(i);
            charCodeArr[i] = charCode;
        }
        var blob = new Blob([new Uint8Array(charCodeArr)], {type: mime_type});
        window.navigator.msSaveOrOpenBlob(blob, file_name);
    }
}

// Example:
initiate_user_download('data.csv', 'text/csv', 'Sample,Data,Here\n1,2,3\n');

If all you really care about is the actual query (the last one run) for quick debugging purposes:

DB::enableQueryLog();

# your laravel query builder goes here

$laQuery = DB::getQueryLog();

$lcWhatYouWant = $laQuery[0]['query']; # <-------

# optionally disable the query log:
DB::disableQueryLog();

do a print_r() on $laQuery[0] to get the full query, including the bindings. (the $lcWhatYouWant variable above will have the variables replaced with ??)

If you're using something other than the main mysql connection, you'll need to use these instead:

DB::connection("mysql2")->enableQueryLog();

DB::connection("mysql2")->getQueryLog();

(with your connection name where "mysql2" is)

ifPresentOrElse can handle cases of nullpointers as well. Easy approach.

   Optional.ofNullable(null)
            .ifPresentOrElse(name -> System.out.println("my name is "+ name),
                    ()->System.out.println("no name or was a null pointer"));

Set your header and footer position to "absolute" and that should do the trick. Hope it helps and good luck with your project!

Same issue happened with me, it might be that Xcode automatically selected another team name, its solved by choosing my correct team name. Good luck !

If you want to check if a string is empty:

if (str[0] == '\0')
{
    // your code here
}

$timeFirst  = strtotime('2011-05-12 18:20:20');
$timeSecond = strtotime('2011-05-13 18:20:20');
$differenceInSeconds = $timeSecond - $timeFirst;

You will then be able to use the seconds to find minutes, hours, days, etc.

Most folks have answered how a downloaded image's dimensions can be known so I'll just try to answer other part of the question - knowing downloaded image's file-size.

You can do this using resource timing api. Very specifically transferSize, encodedBodySize and decodedBodySize properties can be used for the purpose.

Check out my answer here for code snippet and more information if you seek : JavaScript - Get size in bytes from HTML img src

I am sure the following code will help you to get ip address.

<script type="application/javascript">
    function getip(json){
      alert(json.ip); // alerts the ip address
    }
</script>

<script type="application/javascript" src="http://www.telize.com/jsonip?callback=getip"></script>

if you want to get the value attribute (buttonValue) then I'd use:

<script type="text/javascript">
    $(document).ready(function() {
        $('.my_button').click(function() {
            alert($(this).attr('value'));
        });
    });
</script>

I agree that a data structure like a List is the best way to go:

List<Integer> values = new ArrayList<Integer>();
Scanner in = new Scanner(System.in);
int value;
int numValues = 0;
do {
    value = in.nextInt();
    values.add(value);
} while (value >= 1) && (value <= 100);

Or you can just allocate an array of a max size and load values into it:

int maxValues = 100;
int [] values = new int[maxValues];
Scanner in = new Scanner(System.in);
int value;
int numValues = 0;
do {
    value = in.nextInt();
    values[numValues++] = value;
} while (value >= 1) && (value <= 100) && (numValues < maxValues);

>>> str(a if a % 1 else int(a))

This excerpt from the glibc manual 0.02 may also be relevant when researching the topic:

There is a potential problem with the size_t type and versions of GCC prior to release 2.4. ANSI C requires that size_t always be an unsigned type. For compatibility with existing systems' header files, GCC defines size_t in stddef.h' to be whatever type the system'ssys/types.h' defines it to be. Most Unix systems that define size_t in `sys/types.h', define it to be a signed type. Some code in the library depends on size_t being an unsigned type, and will not work correctly if it is signed.

The GNU C library code which expects size_t to be unsigned is correct. The definition of size_t as a signed type is incorrect. We plan that in version 2.4, GCC will always define size_t as an unsigned type, and the fixincludes' script will massage the system'ssys/types.h' so as not to conflict with this.

In the meantime, we work around this problem by telling GCC explicitly to use an unsigned type for size_t when compiling the GNU C library. `configure' will automatically detect what type GCC uses for size_t arrange to override it if necessary.

Simply call list on the generator.

lst = list(gen)
lst

Be aware that this affects the generator which will not return any further items.

You also cannot directly call list in IPython, as it conflicts with a command for listing lines of code.

Tested on this file:

def gen():
    yield 1
    yield 2
    yield 3
    yield 4
    yield 5
import ipdb
ipdb.set_trace()

g1 = gen()

text = "aha" + "bebe"

mylst = range(10, 20)

which when run:

$ python code.py 
> /home/javl/sandbox/so/debug/code.py(10)<module>()
      9 
---> 10 g1 = gen()
     11 

ipdb> n
> /home/javl/sandbox/so/debug/code.py(12)<module>()
     11 
---> 12 text = "aha" + "bebe"
     13 

ipdb> lst = list(g1)
ipdb> lst
[1, 2, 3, 4, 5]
ipdb> q
Exiting Debugger.

General method for escaping function/variable/debugger name conflicts

There are debugger commands p and pp that will print and prettyprint any expression following them.

So you could use it as follows:

$ python code.py 
> /home/javl/sandbox/so/debug/code.py(10)<module>()
      9 
---> 10 g1 = gen()
     11 

ipdb> n
> /home/javl/sandbox/so/debug/code.py(12)<module>()
     11 
---> 12 text = "aha" + "bebe"
     13 

ipdb> p list(g1)
[1, 2, 3, 4, 5]
ipdb> c

There is also an exec command, called by prefixing your expression with !, which forces debugger to take your expression as Python one.

ipdb> !list(g1)
[]

For more details see help p, help pp and help exec when in debugger.

ipdb> help exec
(!) statement
Execute the (one-line) statement in the context of
the current stack frame.
The exclamation point can be omitted unless the first word
of the statement resembles a debugger command.
To assign to a global variable you must always prefix the
command with a 'global' command, e.g.:
(Pdb) global list_options; list_options = ['-l']

You will need to run the following code after your intent is fired to remove the notification.

NotificationManagerCompat.from(this).cancel(null, notificationId);

NB: notificationId is the same id passed to run your notification

I believe this error message is due to a "zombie transaction".

Look for possible areas where the transacton is being committed twice (or rolled back twice, or rolled back and committed, etc.). Does the .Net code commit the transaction after the SP has already committed it? Does the .Net code roll it back on encountering an error, then attempt to roll it back again in a catch (or finally) clause?

It's possible an error condition was never being hit on the old server, and thus the faulty "double rollback" code was never hit. Maybe now you have a situation where there is some configuration error on the new server, and now the faulty code is getting hit via exception handling.

Can you debug into the error code? Do you have a stack trace?

And my 15 cent. A one liner for the mac terminal etc just set the MIN= to whatever and a message

MIN=15 && for i in $(seq $(($MIN*60)) -1 1); do echo "$i, "; sleep 1; done; echo -e "\n\nMac Finder should show a popup" afplay /System/Library/Sounds/Funk.aiff; osascript -e 'tell app "Finder" to display dialog "Look away. Rest your eyes"'

A bonus example for inspiration to combine more commands; this will put a mac put to standby sleep upon the message too :) the sudo login is needed then, a multiplication as the 60*2 for two hours goes aswell

sudo su
clear; echo "\n\nPreparing for a sleep when timers done \n"; MIN=60*2 && for i in $(seq $(($MIN*60)) -1 1); do printf "\r%02d:%02d:%02d" $((i/3600)) $(( (i/60)%60)) $((i%60)); sleep 1; done; echo "\n\n Time to sleep  zzZZ";  afplay /System/Library/Sounds/Funk.aiff; osascript -e 'tell app "Finder" to display dialog "Time to sleep zzZZ"'; shutdown -h +1 -s

Using #selector will check your code at compile time to make sure the method you want to call actually exists. Even better, if the method doesn’t exist, you’ll get a compile error: Xcode will refuse to build your app, thus banishing to oblivion another possible source of bugs.

override func viewDidLoad() {
        super.viewDidLoad()

        navigationItem.rightBarButtonItem =
            UIBarButtonItem(barButtonSystemItem: .Add, target: self,
                            action: #selector(addNewFireflyRefernce))
    }

    func addNewFireflyReference() {
        gratuitousReferences.append("Curse your sudden but inevitable betrayal!")
    }

Another approach would be to use a NOT EXISTS condition in your join condition to test for later purchases:

SELECT *
FROM customer c
LEFT JOIN purchase p ON (
       c.id = p.customer_id
   AND NOT EXISTS (
     SELECT 1 FROM purchase p1
     WHERE p1.customer_id = c.id
     AND p1.id > p.id
   )
)

In Ubuntu I did not found httpd.conf, It may not exit longer now. Edit in apache2.conf file working for me.

cd /etc/apache2
sudo gedit apache2.conf

Here in apache2.conf change

<Directory /var/www/>
     Options Indexes FollowSymLinks
     AllowOverride None
     Require all granted
</Directory>

to

<Directory /var/www/>
        Options Indexes FollowSymLinks
        AllowOverride All
        Require all granted
</Directory>  

The following line will start reading a number (%d) followed by anything different from tabs or newlines (%[^\t\n]).

sscanf("19 cool kid", "%d %[^\t\n]", &age, buffer);

null command [colon] also useful when debugging to see variable's value

set -x
for i in {1..10}; do
    let i=i+1
    : i=$i
done
set - 

As of Android studio 3.4, You need to put this line in your Layout which holds the RecyclerView.

app:layout_behavior="android.support.design.widget.AppBarLayout$ScrollingViewBehavior"

You can bind the mouseenter and mouseleave events and jQuery will emulate those where they are not native.

$("div.system_box").on('mouseenter', function(){
    //enter
})
.on('mouseleave', function(){
    //leave
});

Either cherry-pick the relevant commits into branch aq or merge branch master into branch aq.

You need only to write:

GRANT DBA TO NewDBA;

Because this already makes the user a DB Administrator

well this is simple one to show back button

actionBar.setDisplayHomeAsUpEnabled(true);

and then you can custom the back event at onOptionsItemSelected

case android.R.id.home:
this.finish();
return true;

It means what type of response you want to send to client, some content types like :

 res.setContentType("image/gif");
 res.setContentType("application/pdf");
 res.setContentType("application/zip");

Suppose I have numbers 1 to 10 in cells A2:A11 with my autofilter in A1. I now filter to only show numbers greater then 5 (i.e. 6, 7, 8, 9, 10).

This code will only print visible cells:

Sub SpecialLoop()
    Dim cl As Range, rng As Range

    Set rng = Range("A2:A11")

    For Each cl In rng
        If cl.EntireRow.Hidden = False Then //Use Hidden property to check if filtered or not
            Debug.Print cl
        End If
    Next

End Sub

Perhaps there is a better way with SpecialCells but the above worked for me in Excel 2003.

EDIT

Just found a better way with SpecialCells:

Sub SpecialLoop()
    Dim cl As Range, rng As Range

    Set rng = Range("A2:A11")

    For Each cl In rng.SpecialCells(xlCellTypeVisible)
        Debug.Print cl
    Next cl

End Sub

You can use array_push. It adds the elements to the end of the array, like in a stack.

You could have also done it like this:

$cart = array(13, "foo", $obj);

resulting_list = first_list + [i for i in second_list if i not in first_list]

or also

<input type="text" onkeypress="handleNumber(event, '€ {-10,3} $')" placeholder="€  $" size=25>

with

function handleNumber(event, mask) {
    /* numeric mask with pre, post, minus sign, dots and comma as decimal separator
        {}: positive integer
        {10}: positive integer max 10 digit
        {,3}: positive float max 3 decimal
        {10,3}: positive float max 7 digit and 3 decimal
        {null,null}: positive integer
        {10,null}: positive integer max 10 digit
        {null,3}: positive float max 3 decimal
        {-}: positive or negative integer
        {-10}: positive or negative integer max 10 digit
        {-,3}: positive or negative float max 3 decimal
        {-10,3}: positive or negative float max 7 digit and 3 decimal
    */
    with (event) {
        stopPropagation()
        preventDefault()
        if (!charCode) return
        var c = String.fromCharCode(charCode)
        if (c.match(/[^-\d,]/)) return
        with (target) {
            var txt = value.substring(0, selectionStart) + c + value.substr(selectionEnd)
            var pos = selectionStart + 1
        }
    }
    var dot = count(txt, /\./, pos)
    txt = txt.replace(/[^-\d,]/g,'')

    var mask = mask.match(/^(\D*)\{(-)?(\d*|null)?(?:,(\d+|null))?\}(\D*)$/); if (!mask) return // meglio exception?
    var sign = !!mask[2], decimals = +mask[4], integers = Math.max(0, +mask[3] - (decimals || 0))
    if (!txt.match('^' + (!sign?'':'-?') + '\\d*' + (!decimals?'':'(,\\d*)?') + '$')) return

    txt = txt.split(',')
    if (integers && txt[0] && count(txt[0],/\d/) > integers) return
    if (decimals && txt[1] && txt[1].length > decimals) return
    txt[0] = txt[0].replace(/\B(?=(\d{3})+(?!\d))/g, '.')

    with (event.target) {
        value = mask[1] + txt.join(',') + mask[5]
        selectionStart = selectionEnd = pos + (pos==1 ? mask[1].length : count(value, /\./, pos) - dot) 
    }

    function count(str, c, e) {
        e = e || str.length
        for (var n=0, i=0; i<e; i+=1) if (str.charAt(i).match(c)) n+=1
        return n
    }
}

Option 3

Iterators are faster than using the get operation, since the get operation has to start from the beginning if it has to do some traversal. It probably wouldn't make a difference in an ArrayList, but other data structures could see a noticeable speed difference. This is also compatible with things that aren't lists, like sets.

String[] out = new String[n];
Iterator<String> iterator = in.iterator();
for (int i = 0; i < n && iterator.hasNext(); i++)
    out[i] = iterator.next();

I would suggest updating git. If you downloaded the .pkg then be sure to uninstall it first.

There are plenty of answers here, but I wanted to add something that I commonly use. IF you are in one of the branches that you would like to compare I typically do one of the following. For the sake of this answer we will say that we are in our secondary branch. Depending on what view you need at the time will depend on which you choose, but most of the time I'm using the second option of the two. The first option may be handy if you are trying to revert back to an original copy -- either way, both get the job done!

This will compare master to the branch that we are in (which is secondary) and the original code will be the added lines and the new code will be considered the removed lines

git diff ..master

OR

This will also compare master to the branch that we are in (which is secondary) and the original code will be the old lines and the new code will be the new lines

git diff master..

net use "m:\Server01\my folder" /USER:mynetwork\Administrator "Mypassword" /persistent:yes 

does not work?

Adding following in application.properties worked for me,

security.basic.enabled=false

Remember to restart the application and check in the console.

1. in your sample code you must remove the brackets, because it's not a functional assignment; also for documentary reasons I would suggest you use the := notation (see code sample below)

   2. Application.Thisworkbook refers to the book containing the VBA code, not necessarily the book containing the data, so be cautious.

Express the sheet you're working on as a sheet object and pass it, together with a logical variable to the following sub:

Sub SetProtectionMode(MySheet As Worksheet, ProtectionMode As Boolean)

    If ProtectionMode Then
        MySheet.Protect DrawingObjects:=True, Contents:=True, _
                        AllowSorting:=True, AllowFiltering:=True
    Else
        MySheet.Unprotect
    End If
End Sub

Within the .Protect method you can define what you want to allow/disallow. This code block will switch protection on/off - without password in this example, you can add it as a parameter or hardcoded within the Sub. Anyway somewhere the PW will be hardcoded. If you don't want this, just call the Protection Dialog window and let the user decide what to do:

Application.Dialogs(xlDialogProtectDocument).Show

Hope that helps

Good luck - MikeD

A better way is to use the Stopwatch class:

using System.Diagnostics;
// ...

Stopwatch sw = new Stopwatch();

sw.Start();

// ...

sw.Stop();

Console.WriteLine("Elapsed={0}",sw.Elapsed);

A lot have been analyzed and discussed about a website being detected being driven by Selenium controlled ChromeDriver. Here are my two cents:

According to the article Browser detection using the user agent serving different webpages or services to different browsers is usually not among the best of ideas. The web is meant to be accessible to everyone, regardless of which browser or device an user is using. There are best practices outlined to develop a website to progressively enhance itself based on the feature availability rather than by targeting specific browsers.

However, browsers and standards are not perfect, and there are still some edge cases where some websites still detects the browser and if the browser is driven by Selenium controled WebDriver. Browsers can be detected through different ways and some commonly used mechanisms are as follows:

• Implementing captcha / recaptcha to detect the automatic bots.

You can find a relevant detailed discussion in How does recaptcha 3 know I'm using selenium/chromedriver?

• Detecting the term HeadlessChrome within headless Chrome UserAgent

You can find a relevant detailed discussion in Access Denied page with headless Chrome on Linux while headed Chrome works on windows using Selenium through Python

• Using Bot Management service from Distil Networks

You can find a relevant detailed discussion in Unable to use Selenium to automate Chase site login

• Using Bot Manager service from Akamai

You can find a relevant detailed discussion in Dynamic dropdown doesn't populate with auto suggestions on https://www.nseindia.com/ when values are passed using Selenium and Python

• Using Bot Protection service from Datadome

You can find a relevant detailed discussion in Website using DataDome gets captcha blocked while scraping using Selenium and Python

However, using the user-agent to detect the browser looks simple but doing it well is in fact a bit tougher.

Note: At this point it's worth to mention that: it's very rarely a good idea to use user agent sniffing. There are always better and more broadly compatible way to address a certain issue.

Considerations for browser detection

The idea behind detecting the browser can be either of the following:

• Trying to work around a specific bug in some specific variant or specific version of a webbrowser.
• Trying to check for the existence of a specific feature that some browsers don't yet support.
• Trying to provide different HTML depending on which browser is being used.

Alternative of browser detection through UserAgents

Some of the alternatives of browser detection are as follows:

• Implementing a test to detect how the browser implements the API of a feature and determine how to use it from that. An example was Chrome unflagged experimental lookbehind support in regular expressions.
• Adapting the design technique of Progressive enhancement which would involve developing a website in layers, using a bottom-up approach, starting with a simpler layer and improving the capabilities of the site in successive layers, each using more features.
• Adapting the top-down approach of Graceful degradation in which we build the best possible site using all the features we want and then tweak it to make it work on older browsers.

Solution

To prevent the Selenium driven WebDriver from getting detected, a niche approach would include either/all of the below mentioned approaches:

• Rotating the UserAgent in every execution of your Test Suite using fake_useragent module as follows:

  from selenium import webdriver
  from selenium.webdriver.chrome.options import Options
  from fake_useragent import UserAgent
  
  options = Options()
  ua = UserAgent()
  userAgent = ua.random
  print(userAgent)
  options.add_argument(f'user-agent={userAgent}')
  driver = webdriver.Chrome(chrome_options=options, executable_path=r'C:\WebDrivers\ChromeDriver\chromedriver_win32\chromedriver.exe')
  driver.get("https://www.google.co.in")
  driver.quit()
  

You can find a relevant detailed discussion in Way to change Google Chrome user agent in Selenium?

• Rotating the UserAgent in each of your Tests using Network.setUserAgentOverride through execute_cdp_cmd() as follows:

  from selenium import webdriver
  
  driver = webdriver.Chrome(executable_path=r'C:\WebDrivers\chromedriver.exe')
  print(driver.execute_script("return navigator.userAgent;"))
  # Setting user agent as Chrome/83.0.4103.97
  driver.execute_cdp_cmd('Network.setUserAgentOverride', {"userAgent": 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/83.0.4103.97 Safari/537.36'})
  print(driver.execute_script("return navigator.userAgent;"))
  

You can find a relevant detailed discussion in How to change the User Agent using Selenium and Python

• Changing the property value of navigator for webdriver to undefined as follows:

  driver.execute_cdp_cmd("Page.addScriptToEvaluateOnNewDocument", {
    "source": """
      Object.defineProperty(navigator, 'webdriver', {
        get: () => undefined
      })
    """
  })

In visual studio.

• Create or open a project.
• Right-click project from solution explorer.
• Select "Add service refernce"
• Paste the address with WSDL you received.
• Click OK.

If no errors, you should be able to see the service reference in the object browser and all related methods.

I always forget the syntax so I come to google, but then I never find the one I'm familiar with :P. This is the cleanest to me and more true to what I'd expect in other languages.

i=0
((i++))

echo $i;

I have made this function. It works fine but returns string.

function show_float_val(val,upto = 2){
  var val = parseFloat(val);
  return val.toFixed(upto);
}

use defaultDate()

Set the date to highlight on first opening if the field is blank. Specify either an actual date via a Date object or as a string in the current [[UI/Datepicker#option-dateFormat|dateFormat]], or a number of days from today (e.g. +7) or a string of values and periods ('y' for years, 'm' for months, 'w' for weeks, 'd' for days, e.g. '+1m +7d'), or null for today.

try this

$("[name=trainingStartFromDate]").datepicker({ dateFormat: 'dd-mm-yy', changeYear: true,defaultDate: new Date()});
$("[name=trainingStartToDate]").datepicker({ dateFormat: 'dd-mm-yy', changeYear: true,defaultDate: +15}); 

tmtheme-editor.herokuapp.com seems pretty nice.

assign your required width and height for the textarea and then use. resize: none ; css property which will disable the textarea's stretchable property.

Another way of doing this, using only JavaScript, would be this:

window.addEventListener('resize', functionName);

This fires every time the size changes, like the other answer.

functionName is the name of the function being executed when the window is resized (the brackets on the end aren't necessary).

Using only the portable JAVA API. http://www.oracle.com/technetwork/articles/java/json-1973242.html

    try (JsonReader reader = Json.createReader(new StringReader(yourJSONresponse))) {
        JsonArray arr = reader.readArray();

        List<String> l = arr.getValuesAs(JsonObject.class)
            .stream().map(o -> o.getString("name")).collect(Collectors.toList());
    }

Here is a brief analysis of the difference put out by the Android development team:

https://www.youtube.com/watch?v=MZOf3pOAM6A

The result is that there is a difference, and in very restrained environments with very large lists it could be a noticeable difference. In their testing, the for each loop took twice as long. However, their testing was over an arraylist of 400,000 integers. The actual difference per element in the array was 6 microseconds. I haven't tested and they didn't say, but I would expect the difference to be slightly larger using objects rather than primitives, but even still unless you are building library code where you have no idea the scale of what you will be asked to iterate over, I think the difference is not worth stressing about.

Or if you dont know the url, you can use

hadoop fs -rm -r -f /user/the/path/to/your/dir

A very simple way to do it is:

list1=['']
j=0
for i in com_list:
    if j==0:
        list1[0]=(i['value'])
    else:
        list1.append(i['value'])
    j+=1

Output:

['apple', 'banana', 'cars']

The best way to implement a RESTful search is to consider the search itself to be a resource. Then you can use the POST verb because you are creating a search. You do not have to literally create something in a database in order to use a POST.

For example:

Accept: application/json
Content-Type: application/json
POST http://example.com/people/searches
{
  "terms": {
    "ssn": "123456789"
  },
  "order": { ... },
  ...
}

You are creating a search from the user's standpoint. The implementation details of this are irrelevant. Some RESTful APIs may not even need persistence. That is an implementation detail.

There are quite lots of answer based on situation.

1) Try to replace '$' with "jQuery"

2) Check that code you are executed are always below the main jquery script.

<script src="http://code.jquery.com/jquery-1.11.3.min.js"></script>
<script type="text/javascript">
jQuery(document).ready(function(){

});
</script>

3) Pass $ into the function and add "jQuery" as a main function like below.

<script type="text/javascript">
jQuery(document).ready(function($){

});
</script>

let x be an object then you can do it two ways

x.attr_name = s 
setattr(x, 'attr_name', s)

You can use ancestor. I find that this is easier to read because the element you are actually selecting is at the end of the path.

//span[contains(text(),'someText')]/ancestor::div[contains(@class, 'measure-tab')]

Just to answer the add() vs offer() question (since the other one is perfectly answered imo, and this might not be):

According to JavaDoc on interface Queue, "The offer method inserts an element if possible, otherwise returning false. This differs from the Collection.add method, which can fail to add an element only by throwing an unchecked exception. The offer method is designed for use when failure is a normal, rather than exceptional occurrence, for example, in fixed-capacity (or "bounded") queues."

That means if you can add the element (which should always be the case in a PriorityQueue), they work exactly the same. But if you can't add the element, offer() will give you a nice and pretty false return, while add() throws a nasty unchecked exception that you don't want in your code. If failure to add means code is working as intended and/or it is something you'll check normally, use offer(). If failure to add means something is broken, use add() and handle the resulting exception thrown according to the Collection interface's specifications.

They are both implemented this way to fullfill the contract on the Queue interface that specifies offer() fails by returning a false (method preferred in capacity-restricted queues) and also maintain the contract on the Collection interface that specifies add() always fails by throwing an exception.

Anyway, hope that clarifies at least that part of the question.

It is because you are in a try statement. Since there could be an error, sum might not get initialized, so put your return statement in the finally block, that way it will for sure be returned.

Make sure that you initialize sum outside the try/catch/finally so that it is in scope.

The first thing i noticed is that you have a semi colon just after your closing bracket for your if statement );

You should also try and clean up your if statement by declaring a variable for the answer separately.

function answers() {

var select = document.getElementById("mySelect");
var answer = select.options[select.selectedIndex].value;

    if(answer == "To measure time"){
        alert("Thats correct"); 
    }

}

Continuous Integration

I Agree with your university's definition. Continuous Integration is a strategy for how a developer can integrate code to the mainline continuously - as opposed to frequently.

You might claim that it's merely a branching strategy in your version control system.

It has to do with the size of the tasks you assign to a developer; If a task is estimated to take 4-5 man-days then the developer will have no incitement to deliver anything for the next 4-5 days, because he's not done with anything - yet.

So size matters:

small task = continuous integration
big task   = frequent integration

The ideal task size is not bigger than a day's work. This way a developer will naturally have at least one integration per day.

Continuous Delivery

There are basically three schools within Continuous Delivery:

Continuous Delivery is a natural extension of Continuous Integration

This school, looks at the Addison-Wesley "Martin Fowler" signature series and makes the assumption that since the 2007 release was called "Continuous Integration" and the one that followed in 2011 was called "Continuous Delivery" they are probably volume 1+2 of the same conceptual idea that has to do with continuous something.

Continuous Delivery has to do with Agile Software Development

This school takes off-set in the idea that Continuous Delivery is all about being able to support the principles in the agile movement, not just as a conceptual idea or a letter of intent but for real - in real life.

Taking offset in the first principle in the Agile Manifesto where the term "continuous delivery" is actually used for the first time:

Our highest priority is to satisfy the customer through early and continuous delivery of valuable software.

This school claims that "Continuous Delivery" is a paradigm that embraces everything required to implement an automated verification of your "definition of done".

This school accepts that "Continuous Delivery" and the buzz word or megatrend "DevOps" are flip sides of the same coin, in the sense that they both try to embrace or encapsulate this new paradigm or approach and not just a technique.

Continuous Delivery is a synonym to Continuous Deployment

The third school advocates that Continuous Deployment and Continuous Delivery can be used interchangeably to mean the same thing.

When something is ready in the hands of the developers, it's immediately delivered to the end-users, which in most cases will mean that it should be deployed to the production environment. Hence "Deploy" and "Deliver" means the same.

Which school to join

Your university clearly joined the first school and claims that we're referring to volume 1+2 of the same publication series. My opinion is that this is a misuse of the term Continuous Delivery.

I personally advocate for the understanding that Continuous Delivery is related to implementing a real-life support for the ideas and concepts stated by the agile movement. So I joined the school that says the term embraces a whole paradigm - like "DevOps".

The school that uses delivery as a synonym to deploy is mostly advocated by tool vendors who create deployment consoles, trying to get a bit of hype from the more widespread use of the term Continuous Delivery.

Continuous Deployment

The focus on Continuous Deployment is mostly relevant in domains where the end user's access to software updates relies on the update of some centralized source for this information and where this centralized source is not always easy to update because it's monolithic or has (too) high coherence by nature (web, SOA, Databases etc.).

For a lot of domains that produces software where there is no centralized source of information (devices, consumer products, client installations etc.) or where the centralized source for information is easy to update (app stores artifact management systems, Open Source repositories etc.), there is almost no hype about the term Continuous Deployment at all. They just deploy; it's not a big thing - it's not a pain that requires special focus.

The fact that Continuous Deployment is not something that is generically interesting to everyone is also an argument that the school that claims that "delivery" and "deploy" are synonyms got it all wrong. Because Continuous Delivery actually makes perfectly good sense to everyone - even if you are doing embedded software in devices or releasing Open Source plugins for a framework.

Your university's definition that Continuous Deployment is a natural next step of Continuous Delivery implicitly assumes that every delivery that is QA'ed should go become available to the end-users immediately, is closer to the definition that my tribe use to describe the term "Continous Release", which, in turn, is another concept that doesn't generically makes sense to everyone either.

A release can be a very strategic or political thing and there is no reason to assume that everybody would want to do this all the time (unless they are an online bookstore a streaming service type of company). Nevertheless, companies that don't blindly release everything all the time may have any number of reasons why they would want to be masters of deployment anyway, so they too do Continuous Deployment. Not of release to production, but of release-candidates to production-like environments.

Again I believe your university got it wrong. They are mistaking "Continuous Deployment" for "Continuous Release".

Continuous deployment is simply the discipline of continuously being able to move the result of a development process to a production-like environment where functional testing can be executed in full scale.

The Continuous Delivery Storyline

In the picture it all comes alive:

The Continuous Integration process is the first two actions in the state-transition diagram. which - if successful - kicks off the Continuous Delivery pipeline that implements the definition of done. Deployment is just one of the many actions that will have to be done continuously in this pipeline. Ideally, the process is automated from the point where the developer commits to the VCS to the point where the pipeline has confirmed that we have a valid release candidate.

From GNU Make error appendix, as you see this is not a Make error but an error coming from gcc.

‘[foo] Error NN’ ‘[foo] signal description’ These errors are not really make errors at all. They mean that a program that make invoked as part of a recipe returned a non-0 error code (‘Error NN’), which make interprets as failure, or it exited in some other abnormal fashion (with a signal of some type). See Errors in Recipes. If no *** is attached to the message, then the subprocess failed but the rule in the makefile was prefixed with the - special character, so make ignored the error.

So in order to attack the problem, the error message from gcc is required. Paste the command in the Makefile directly to the command line and see what gcc says. For more details on Make errors click here.

you can use regex in order to catch any length of white space, and this would be like:

var text = "hoi how     are          you";
var arr = text.split(/\s+/);

console.log(arr) // will result : ["hoi", "how", "are", "you"]

console.log(arr[2]) // will result : "are"

UPDATE - April '15:

If you want to get the count that is available in the Like button, you should use the engagement field in the og_object object, like so:

https://graph.facebook.com/v2.2/?id=http://www.MY-LINK.com&fields=og_object{engagement}&access_token=<access_token>

Result:

{
  "og_object": {
    "engagement": {
      "count": 93, 
      "social_sentence": "93 people like this."
    }, 
    "id": "801998203216179"
  }, 
  "id": "http://techcrunch.com/2015/04/06/they-should-have-announced-at-420/"
}

It's possible with the Graph API, simply use:

http://graph.facebook.com/?id=YOUR_URL

something like:

http://graph.facebook.com/?id=http://www.google.com

Would return:

{
   "id": "http://www.google.com",
   "shares": 1163912
}

UPDATE: while the above would answer how to get the share count. This number is not equal to the one you see on the Like Button, since that number is the sum of:

• The number of likes of this URL
• The number of shares of this URL (this includes copy/pasting a link back to Facebook)
• The number of likes and comments on stories on Facebook about this URL
• The number of inbox messages containing this URL as an attachment.

So getting the Like Button number is possible with the Graph API through the fql end-point (the link_stat table):

https://graph.facebook.com/fql?q=SELECT url, normalized_url, share_count, like_count, comment_count, total_count,commentsbox_count, comments_fbid, click_count FROM link_stat WHERE url='http://www.google.com'

total_count is the number that shows in the Like Button.

What you actually created with:

MyType[] list = []

Was fixed size array (not list) with size of 0. You can create fixed size array of size for example 4 with:

MyType[] array = new MyType[4]

But there's no add method of course.

If you create list with def it's something like creating this instance with Object (You can read more about def here). And [] creates empty ArrayList in this case.

So using def list = [] you can then append new items with add() method of ArrayList

list.add(new MyType())

Or more groovy way with overloaded left shift operator:

list << new MyType() 

As I can't yet comment (muhuk's solution), I'll response as a separate answer. This is a complete code example, that worked for me:

def clean_sku(self):
  if self.instance and self.instance.pk:
    return self.instance.sku
  else:
    return self.cleaned_data['sku']

Right...with strings...the moment you deviate from primitives or strings things change and you need to implement hashcode/equals to get the desired effect.

EDIT: Initialize your ArrayList<String> then attempt to add an item.

Step 1

• Search → Find → (goto Tab) Mark
• Find what: ^Session.*$

• Enable the checkbox Regular expression (under Search Mode)
• Click Mark All (this will find the regex and highlights all the lines and bookmark them)

Step 2

• Search → Bookmark → Remove Bookmarked Lines

It should work. Try this

var label:UILabel = UILabel(frame: CGRectMake(10
    ,100, 300, 40));
label.textAlignment = NSTextAlignment.Center;
label.numberOfLines = 0;
label.font = UIFont.systemFontOfSize(16.0);
label.text = "First label\nsecond line";
self.view.addSubview(label);

Yet another solution would be to use the isin method. Use it to determine whether each value is infinite or missing and then chain the all method to determine if all the values in the rows are infinite or missing.

Finally, use the negation of that result to select the rows that don't have all infinite or missing values via boolean indexing.

all_inf_or_nan = df.isin([np.inf, -np.inf, np.nan]).all(axis='columns')
df[~all_inf_or_nan]

My personal preference is to delete the branch name after I’m done with a topic branch.

Instead of trying to use the branch name to explain the meaning of the branch, I start the subject line of the commit message in the first commit on that branch with “Branch:” and include further explanations in the body of the message if the subject does not give me enough space.

The branch name in my use is purely a handle for referring to a topic branch while working on it. Once work on the topic branch has concluded, I get rid of the branch name, sometimes tagging the commit for later reference.

That makes the output of git branch more useful as well: it only lists long-lived branches and active topic branches, not all branches ever.

Join on one-to-many relation in JPQL looks as follows:

select b.fname, b.lname from Users b JOIN b.groups c where c.groupName = :groupName 

When several properties are specified in select clause, result is returned as Object[]:

Object[] temp = (Object[]) em.createNamedQuery("...")
    .setParameter("groupName", groupName)
    .getSingleResult(); 
String fname = (String) temp[0];
String lname = (String) temp[1];

By the way, why your entities are named in plural form, it's confusing. If you want to have table names in plural, you may use @Table to specify the table name for the entity explicitly, so it doesn't interfere with reserved words:

@Entity @Table(name = "Users")     
public class User implements Serializable { ... }
