Fix: Unlock your device before running it.

Hi Guys: Think I may have a fix for this:

Sounds ridiculous but try unlocking your Virtual Device; i.e. use your mouse to swipe and open. Your app should then work!!

The following code fetches a JSON object from a webserver, and parses it to an NSDictionary. I have used the openweathermap API that returns a simple JSON response for this example. For keeping it simple, this code uses synchronous requests.

   NSString *urlString   = @"http://api.openweathermap.org/data/2.5/weather?q=London,uk"; // The Openweathermap JSON responder
   NSURL *url            = [[NSURL alloc]initWithString:urlString];
   NSURLRequest *request = [NSURLRequest requestWithURL:url];
   NSURLResponse *response;
   NSData *GETReply      = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:nil];
   NSDictionary *res     = [NSJSONSerialization JSONObjectWithData:GETReply options:NSJSONReadingMutableLeaves|| NSJSONReadingMutableContainers error:nil];
   Nslog(@"%@",res);

Have <option value="">- Please select a name -</option> as the first option and use JavaScript (and backend validation) to ensure the user has selected something other than an empty value.

You could achieve this without having to import traceback:

try:
    func1()
except Exception as ex:
    trace = []
    tb = ex.__traceback__
    while tb is not None:
        trace.append({
            "filename": tb.tb_frame.f_code.co_filename,
            "name": tb.tb_frame.f_code.co_name,
            "lineno": tb.tb_lineno
        })
        tb = tb.tb_next
    print(str({
        'type': type(ex).__name__,
        'message': str(ex),
        'trace': trace
    }))

Output:

{

  'type': 'ZeroDivisionError',
  'message': 'division by zero',
  'trace': [
    {
      'filename': '/var/playground/main.py',
      'name': '<module>',
      'lineno': 16
    },
    {
      'filename': '/var/playground/main.py',
      'name': 'func1',
      'lineno': 11
    },
    {
      'filename': '/var/playground/main.py',
      'name': 'func2',
      'lineno': 7
    },
    {
      'filename': '/var/playground/my.py',
      'name': 'test',
      'lineno': 2
    }
  ]
}

The answer will not work when using the overload to indicate the template @Html.DisplayFor(x => x.Foos, "YourTemplateName) .

Seems to be designed that way, see this case. Also the exception the framework gives (about the type not been as expected) is quite misleading and fooled me on the first try (thanks @CodeCaster)

In this case you have to use @foreach

@foreach (var item in Model.Foos)
{
    @Html.DisplayFor(x => item, "FooTemplate")
}

I use this method as a wrapper so that I can send parameters. Also using the variables in the top of the method allows it to be minimized at a higher ratio and allows for some code reuse if making multiple similar calls.

function InfoByDate(sDate, eDate){
    var divToBeWorkedOn = "#AjaxPlaceHolder";
    var webMethod = "http://MyWebService/Web.asmx/GetInfoByDates";
    var parameters = "{'sDate':'" + sDate + "','eDate':'" + eDate + "'}";

    $.ajax({
        type: "POST",
        url: webMethod,
        data: parameters,
        contentType: "application/json; charset=utf-8",
        dataType: "json",
        success: function(msg) {
            $(divToBeWorkedOn).html(msg.d);
        },
        error: function(e){
            $(divToBeWorkedOn).html("Unavailable");
        }
    });
}

I hope that helps.

Please note that this requires the 3.5 framework to expose JSON webmethods that can be consumed in this manner.

I listen for WifiManager.NETWORK_STATE_CHANGED_ACTION in a broadcast receiver

if (WifiManager.NETWORK_STATE_CHANGED_ACTION.equals (action)) {
        NetworkInfo netInfo = intent.getParcelableExtra (WifiManager.EXTRA_NETWORK_INFO);
        if (ConnectivityManager.TYPE_WIFI == netInfo.getType ()) {

I check for netInfo.isConnected (). Then I am able to use

WifiManager wifiManager = (WifiManager) getSystemService (Context.WIFI_SERVICE);
WifiInfo info = wifiManager.getConnectionInfo ();
String ssid  = info.getSSID();

UPDATE

From android 8.0 onwards we wont be getting SSID of the connected network unless GPS is turned on.

Use the following:

SELECT * FROM `calendar` WHERE DATE(startTime) = '2010-04-29'

Just for reference I have a 2 million record table, I ran a similar query. Salils answer took 4.48 seconds, the above took 2.25 seconds.

So if the table is BIG I would suggest this rather.

I have a similar scenario, and had no problem connecting after setting the JNLP port as you describe, and adding a single firewall rule allowing a connection on the server using that port. Granted it is a randomly selected client port going to a known server port (a host:ANY -> server:1 rule is needed).

From my reading of the source code, I don't see a way to set the local port to use when making the request from the slave. It's unfortunate, it would be a nice feature to have.

Alternatives:

Use a simple proxy on your client that listens on port N and then does forward all data to the actual Jenkins server on the remote host using a constant local port. Connect your slave to this local proxy instead of the real Jenkins server.

Create a custom Jenkins slave build that allows an option to specify the local port to use.

Remember also if you are using HTTPS via a self-signed certificate, you must alter the configuration jenkins-slave.xml file on the slave to specify the -noCertificateCheck option on the command line.

It's called a for-each or enhanced for statement. See the JLS §14.14.2.

It's syntactic sugar provided by the compiler for iterating over Iterables and arrays. The following are equivalent ways to iterate over a list:

List<Foo> foos = ...;
for (Foo foo : foos)
{
    foo.bar();
}

// equivalent to:
List<Foo> foos = ...;
for (Iterator<Foo> iter = foos.iterator(); iter.hasNext();)
{
    Foo foo = iter.next();
    foo.bar();
}

and these are two equivalent ways to iterate over an array:

int[] nums = ...;
for (int num : nums)
{
    System.out.println(num);
}

// equivalent to:
int[] nums = ...;
for (int i=0; i<nums.length; i++)
{
    int num = nums[i];
    System.out.println(num);
}

You cannot get stdout to print unbuffered to a pipe (unless you can rewrite the program that prints to stdout), so here is my solution:

Redirect stdout to sterr, which is not buffered. '<cmd> 1>&2' should do it. Open the process as follows: myproc = subprocess.Popen('<cmd> 1>&2', stderr=subprocess.PIPE)
You cannot distinguish from stdout or stderr, but you get all output immediately.

Hope this helps anyone tackling this problem.

Don't use wsgiref for production. Use Apache and mod_wsgi, or something else.

We continue to see these connection resets, sometimes frequently, with wsgiref (the backend used by the werkzeug test server, and possibly others like the Django test server). Our solution was to log the error, retry the call in a loop, and give up after ten failures. httplib2 tries twice, but we needed a few more. They seem to come in bunches as well - adding a 1 second sleep might clear the issue.

We've never seen a connection reset when running through Apache and mod_wsgi. I don't know what they do differently, (maybe they just mask them), but they don't appear.

When we asked the local dev community for help, someone confirmed that they see a lot of connection resets with wsgiref that go away on the production server. There's a bug there, but it is going to be hard to find it.

For disable trigger

ALTER TABLE table_name DISABLE TRIGGER trigger_name

For enable trigger

ALTER TABLE table_name ENABLE TRIGGER trigger_name

There is, however, no guarantee that the output of SDTOUT and STDERR are interweaved line-by-line in timely order, using the POSIX redirect merge syntax.

If an application uses buffered output, it may happen that the text of one stream is inserted in the other at a buffer boundary, which may appear in the middle of a text line.

A dedicated console output logger (I.e. the "StdOut/StdErr Logger" by 'LoRd MuldeR') may be more reliable for such a task.

See: MuldeR's OpenSource Projects

Direct Javascript calls between frames and/or windows are only allowed if they conform to the same-origin policy. If your window and iframe share a common parent domain you can set document.domain to "domain lower") one or both such that they can communicate. Otherwise you'll need to look into something like the postMessage() API.

Try this:

<?php 
/*
Template Name: [contact us]

*/
get_header();
echo do_shortcode('[CONTACT-US-FORM]'); 
?>

The use of cron on OS X is discouraged. launchd is used instead. Try man launchctl to get started. You have to create special XML files that define your jobs and put them in a special place with certain permissions.

You'll usually just need to figure out launchctl load

http://developer.apple.com/library/mac/#documentation/Darwin/Reference/ManPages/man1/launchctl.1.html

http://nb.nathanamy.org/2012/07/schedule-jobs-using-launchd/

Edit

If you really do want to use cron on OS X, check out this answer: https://superuser.com/a/243944/2449

The syntax is wrong. The typedef should be removed.

Make the header looks like this for HttpClient in NG5:

let httpOptions = {
      headers: new HttpHeaders({
        'Content-Type': 'application/json',
        'apikey': this.apikey,
        'appkey': this.appkey,
      }),
      params: new HttpParams().set('program_id', this.program_id)
    };

You will be able to make api call with your localhost url, it works for me ..

• Please never forget your params columnd in the header: such as params: new HttpParams().set('program_id', this.program_id)

You can simply cast to List and then check if every element can be casted to T.

public <T> List<T> asList(final Class<T> clazz) {
    List<T> values = (List<T>) this.value;
    values.forEach(clazz::cast);
    return values;
}

Both UTF8 and UTF-8 work for me.

The Node REPL uses the underscore variable to hold the result of the last operation, so it conflicts with the Underscore library's use of the same variable. Try something like this:

Admin-MacBook-Pro:test admin$ node
> _und = require("./underscore-min")
{ [Function]
  _: [Circular],
  VERSION: '1.1.4',
  forEach: [Function],
  each: [Function],
  map: [Function],
  inject: [Function],
  (...more functions...)
  templateSettings: { evaluate: /<%([\s\S]+?)%>/g, interpolate: /<%=([\s\S]+?)%>/g },
  template: [Function] }
> _und.max([1,2,3])
3
> _und.max([4,5,6])
6

For a string of length 1 you can simply perform isdigit() or isalpha()

If your string length is greater than 1, you can make a function something like..

def isinteger(a):
    try:
        int(a)
        return True
    except ValueError:
        return False

I solved this problem, I changed build system to Legacy Build System from New Build System

In Xcode v10+, select File > Project Settings

In previous Xcode, select File > Workspace Settings

Change Build System to Legacy Build System from New Build System --> Click Done.

See also std::remove_if to be able to use a predicate...

Here's the example from the link above:

vector<int> V;
V.push_back(1);
V.push_back(4);
V.push_back(2);
V.push_back(8);
V.push_back(5);
V.push_back(7);

copy(V.begin(), V.end(), ostream_iterator<int>(cout, " "));
    // The output is "1 4 2 8 5 7"

vector<int>::iterator new_end = 
    remove_if(V.begin(), V.end(), 
              compose1(bind2nd(equal_to<int>(), 0),
                       bind2nd(modulus<int>(), 2)));
V.erase(new_end, V.end()); [1]

copy(V.begin(), V.end(), ostream_iterator<int>(cout, " "));
    // The output is "1 5 7".

First: it can be done without HTML5 Canvas or SVG.
Actually, someone just managed to generate client-side PNG files using JavaScript, without canvas or SVG, using the data URI scheme.

Second: you might actually not need Canvas, SVG or any of the above at all.
If you only need to process images on the client side, without modifying them, all this is not needed.

You can get the source address from the img tag on the page, make an XHR request for it - it will most probably come from the browser cache - and process it as a byte stream from Javascript.
You will need a good understanding of the image format. (The above generator is partially based on libpng sources and might provide a good starting point.)

Another option would be:

SELECT * FROM [Village] WHERE PATINDEX('foo', [CastleType]) <> 0

Is there a way to initialize the EntityManager without a persistence unit defined?

You should define at least one persistence unit in the persistence.xml deployment descriptor.

Can you give all the required properties to create an Entitymanager?

• The name attribute is required. The other attributes and elements are optional. (JPA specification). So this should be more or less your minimal persistence.xml file:

<persistence>
    <persistence-unit name="[REQUIRED_PERSISTENCE_UNIT_NAME_GOES_HERE]">
        SOME_PROPERTIES
    </persistence-unit>
</persistence>

In Java EE environments, the jta-data-source and non-jta-data-source elements are used to specify the global JNDI name of the JTA and/or non-JTA data source to be used by the persistence provider.

So if your target Application Server supports JTA (JBoss, Websphere, GlassFish), your persistence.xml looks like:

<persistence>
    <persistence-unit name="[REQUIRED_PERSISTENCE_UNIT_NAME_GOES_HERE]">
        <!--GLOBAL_JNDI_GOES_HERE-->
        <jta-data-source>jdbc/myDS</jta-data-source>
    </persistence-unit>
</persistence>

If your target Application Server does not support JTA (Tomcat), your persistence.xml looks like:

<persistence>
    <persistence-unit name="[REQUIRED_PERSISTENCE_UNIT_NAME_GOES_HERE]">
        <!--GLOBAL_JNDI_GOES_HERE-->
        <non-jta-data-source>jdbc/myDS</non-jta-data-source>
    </persistence-unit>
</persistence>

If your data source is not bound to a global JNDI (for instance, outside a Java EE container), so you would usually define JPA provider, driver, url, user and password properties. But property name depends on the JPA provider. So, for Hibernate as JPA provider, your persistence.xml file will looks like:

<persistence>
    <persistence-unit name="[REQUIRED_PERSISTENCE_UNIT_NAME_GOES_HERE]">
        <provider>org.hibernate.ejb.HibernatePersistence</provider>
        <class>br.com.persistence.SomeClass</class>
        <properties>
            <property name="hibernate.connection.driver_class" value="org.apache.derby.jdbc.ClientDriver"/>
            <property name="hibernate.connection.url" value="jdbc:derby://localhost:1527/EmpServDB;create=true"/>
            <property name="hibernate.connection.username" value="APP"/>
            <property name="hibernate.connection.password" value="APP"/>
        </properties>
    </persistence-unit>
</persistence>

Transaction Type Attribute

In general, in Java EE environments, a transaction-type of RESOURCE_LOCAL assumes that a non-JTA datasource will be provided. In a Java EE environment, if this element is not specified, the default is JTA. In a Java SE environment, if this element is not specified, a default of RESOURCE_LOCAL may be assumed.

• To insure the portability of a Java SE application, it is necessary to explicitly list the managed persistence classes that are included in the persistence unit (JPA specification)

I need to create the EntityManager from the user's specified values at runtime

So use this:

Map addedOrOverridenProperties = new HashMap();

// Let's suppose we are using Hibernate as JPA provider
addedOrOverridenProperties.put("hibernate.show_sql", true);

Persistence.createEntityManagerFactory(<PERSISTENCE_UNIT_NAME_GOES_HERE>, addedOrOverridenProperties);

In Java there is no direct way to get browser and OS related information.

But to get this few third-party tools are available.

Instead of trusting third-party tools, I suggest you to parse the user agent.

String  browserDetails  =   request.getHeader("User-Agent");

By doing this you can separate the browser details and OS related information easily according to your requirement. PFB the snippet for reference.

        String  browserDetails  =   request.getHeader("User-Agent");
        String  userAgent       =   browserDetails;
        String  user            =   userAgent.toLowerCase();

        String os = "";
        String browser = "";

        log.info("User Agent for the request is===>"+browserDetails);

Well, I have tried something I hope it helps ..

They changed the schema a little bit ..

Use the following :

1- Change the AccessDataSource to SQLDataSource in the toolbox.

2- In the drop down menu choose your access database (xxxx.accdb or xxxx.mdb)

3- Next -> Next -> Test Query -> Finish.

Worked for me.

I use it in form of a meta box. Here is a function that dumps values of all the meta data for post.

    function dump_all_meta(){

        echo "<h3>All Post Meta</h3>";

        // Get all the data.
        $getPostCustom=get_post_custom();


        foreach( $getPostCustom as $name=>$value ) {

            echo "<strong>".$name."</strong>"."  =>  ";

            foreach($getPostCustom as $name=>$value) {

        echo "<strong>".$name."</strong>"."  =>  ";

        foreach($value as $nameAr=>$valueAr) {
                echo "<br />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;";
                echo $nameAr."  =>  ";
                echo var_dump($valueAr);
        }

        echo "<br /><br />";

        }
    } // Callback funtion ended.

Hope it helps. You can use it inside a meta box or at the front-end.

I found one good thing about using bind is that you get to know the trigger event: something like: "You clicked with event = [ButtonPress event state=Mod1 num=1 x=43 y=20]" due to the code below:

self.submit.bind('<Button-1>', self.parse)
def parse(self, trigger_event):
        print("You clicked with event = {}".format(trigger_event))

Comparing the following two ways of coding a button click:

btn = Button(root, text="Click me to submit", command=(lambda: reply(ent.get())))
btn = Button(root, text="Click me to submit")
btn.bind('<Button-1>', (lambda event: reply(ent.get(), e=event)))
def reply(name, e = None):
    messagebox.showinfo(title="Reply", message = "Hello {0}!\nevent = {1}".format(name, e))

The first one is using the command function which doesn't take an argument, so no event pass-in is possible. The second one is a bind function which can take an event pass-in and print something like "Hello Charles! event = [ButtonPress event state=Mod1 num=1 x=68 y=12]"

We can left click, middle click or right click a mouse which corresponds to the event number of 1, 2 and 3, respectively. Code:

btn = Button(root, text="Click me to submit")
buttonClicks = ["<Button-1>", "<Button-2>", "<Button-3>"]
for bc in buttonClicks:
    btn.bind(bc, lambda e : print("Button clicked with event = {}".format(e.num)))

Output:

Button clicked with event = 1
Button clicked with event = 2
Button clicked with event = 3

1. Using header, a built-in PHP function

a) Simple redirect without parameters

<?php
   header('Location: index.php');
?>

b) Redirect with GET parameters

<?php
      $id = 2;
      header("Location: index.php?id=$id&msg=succesfully redirect");
  ?>

2. Redirect with JavaScript in PHP

a) Simple redirect without parameters

<?php
     echo "<script>location.href='index.php';</script>";
 ?>

b) Redirect with GET parameters

<?php
     $id = 2;
     echo "<script>location.href='index.php?id=$id&msg=succesfully redirect';</script>";
   ?>

I had the same problem and the "Microsoft.Web.Infrastructure.dll" appeared to be missing. I have tried few advises and installed MVC`s etc. and nothing helped. The solution was to install "Web Services Enhancements (WSE) 1.0 SP1 for Microsoft .NET" which includes Microsoft.Web.Infrastructure.dll. Available at: http://www.microsoft.com/en-gb/download/details.aspx?id=4065

I found this snippet to work well when switching between X and no-X environments.

import os
import matplotlib as mpl
if os.environ.get('DISPLAY','') == '':
    print('no display found. Using non-interactive Agg backend')
    mpl.use('Agg')
import matplotlib.pyplot as plt

.inspect is what you're looking for, it's way easier IMO than .to_yaml!

user = User.new
user.name = "will"
user.email = "[email protected]"

user.inspect
#<name: "will", email: "[email protected]">

Strictly speaking, there is no single configuration file. Excluding ASP.NET¹ there can be three configuration files using the inbuilt (System.Configuration) support. In addition to the machine config: app.exe.config, user roaming, and user local.

To get the "global" configuration (exe.config):

ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None)
                    .FilePath

Use different ConfigurationUserLevel values for per-use roaming and non-roaming configuration files.

¹ Which has a completely different model where the content of a child folders (IIS-virtual or file system) web.config can (depending on the setting) add to or override the parent's web.config.

Check for id. It may have root permissions.

So type su and then execute the script as ./scripts/replace-md5sums.py.

It works.

Use this code:

<!DOCTYPE html>
<html>
<head>
<style>
.text-center{
    text-align:center;
    margin-left:auto;
    margin-right:auto;
}
</style>
</head>
<body>

<div class="text-center">
<canvas id="myCanvas" width="200" height="100" style="border:1px solid #000000;">
Your browser does not support the HTML5 canvas tag.
</canvas>
</div>

</body>
</html>

In the Html

<div id="AssignUniqueId" runat="server">.....BLAH......<div/>

In the code

public void Page_Load(object source, Event Args e)
{

   if(Session["Something"] == "ShowDiv")
      AssignUniqueId.Visible = true;
    else
      AssignUniqueID.Visible = false;
}

I know it's a bit late but I had issues with a modal window not allowing some links on the menu bar to work, even when it has not been triggered. But I solved it by doing the following:

.modal{
display:none;
}

swift 4:

let username = "username"
let password = "password"
let loginString = "\(username):\(password)"

guard let loginData = loginString.data(using: String.Encoding.utf8) else {
    return
}
let base64LoginString = loginData.base64EncodedString()

request.httpMethod = "GET"
request.setValue("Basic \(base64LoginString)", forHTTPHeaderField: "Authorization")

An optional means that Swift is not entirely sure if the value corresponds to the type: for example, Int? means that Swift is not entirely sure whether the number is an Int.

To remove it, there are three methods you could employ.

1) If you are absolutely sure of the type, you can use an exclamation mark to force unwrap it, like this:

// Here is an optional variable:

var age: Int?

// Here is how you would force unwrap it:

var unwrappedAge = age!

If you do force unwrap an optional and it is equal to nil, you may encounter this crash error:

This is not necessarily safe, so here's a method that might prevent crashing in case you are not certain of the type and value:

Methods 2 and three safeguard against this problem.

2) The Implicitly Unwrapped Optional

 if let unwrappedAge = age {

 // continue in here

 }

Note that the unwrapped type is now Int, rather than Int?.

3) The guard statement

 guard let unwrappedAge = age else { 
   // continue in here
 }

From here, you can go ahead and use the unwrapped variable. Make sure only to force unwrap (with an !), if you are sure of the type of the variable.

Good luck with your project!

Here is a bash-only parser that leverages sed and awk to parse simple yaml files:

function parse_yaml {
   local prefix=$2
   local s='[[:space:]]*' w='[a-zA-Z0-9_]*' fs=$(echo @|tr @ '\034')
   sed -ne "s|^\($s\):|\1|" \
        -e "s|^\($s\)\($w\)$s:$s[\"']\(.*\)[\"']$s\$|\1$fs\2$fs\3|p" \
        -e "s|^\($s\)\($w\)$s:$s\(.*\)$s\$|\1$fs\2$fs\3|p"  $1 |
   awk -F$fs '{
      indent = length($1)/2;
      vname[indent] = $2;
      for (i in vname) {if (i > indent) {delete vname[i]}}
      if (length($3) > 0) {
         vn=""; for (i=0; i<indent; i++) {vn=(vn)(vname[i])("_")}
         printf("%s%s%s=\"%s\"\n", "'$prefix'",vn, $2, $3);
      }
   }'
}

It understands files such as:

## global definitions
global:
  debug: yes
  verbose: no
  debugging:
    detailed: no
    header: "debugging started"

## output
output:
   file: "yes"

Which, when parsed using:

parse_yaml sample.yml

will output:

global_debug="yes"
global_verbose="no"
global_debugging_detailed="no"
global_debugging_header="debugging started"
output_file="yes"

it also understands yaml files, generated by ruby which may include ruby symbols, like:

---
:global:
  :debug: 'yes'
  :verbose: 'no'
  :debugging:
    :detailed: 'no'
    :header: debugging started
  :output: 'yes'

and will output the same as in the previous example.

typical use within a script is:

eval $(parse_yaml sample.yml)

parse_yaml accepts a prefix argument so that imported settings all have a common prefix (which will reduce the risk of namespace collisions).

parse_yaml sample.yml "CONF_"

yields:

CONF_global_debug="yes"
CONF_global_verbose="no"
CONF_global_debugging_detailed="no"
CONF_global_debugging_header="debugging started"
CONF_output_file="yes"

Note that previous settings in a file can be referred to by later settings:

## global definitions
global:
  debug: yes
  verbose: no
  debugging:
    detailed: no
    header: "debugging started"

## output
output:
   debug: $global_debug

Another nice usage is to first parse a defaults file and then the user settings, which works since the latter settings overrides the first ones:

eval $(parse_yaml defaults.yml)
eval $(parse_yaml project.yml)

Just use Date.parse() which returns a Number, then use new Date() to parse it:

var thedate = new Date(Date.parse("2011-07-14 11:23:00"));

return; will exit a method in C#.

See code snippet below

using System;

namespace Exercise_strings
{
    class Program
    {
        static void Main(string[] args)
        {
           Console.WriteLine("Input string separated by -");

            var stringInput = Console.ReadLine();

            if (string.IsNullOrWhiteSpace(stringInput))
            {
                Console.WriteLine("Nothing entered");
                return;
            }
}

So in this case if a user enters a null string or whitespace, the use of the return method terminates the Main method elegantly.

Try that:

/bin/dd if=/dev/zero of=/var/swap.1 bs=1M count=1024

/sbin/mkswap /var/swap.1

/sbin/swapon /var/swap.1

Semantically, you're probably looking for the one-liner

new Date().toLocaleString()

which formats the date in the locale of the user.

If you're really looking for a specific way to format dates, I recommend the moment.js library.

You can increase the List View Threshold beyond the 5,000 default, but it is highly recommended that you don't, as it has performance implications. The recommended fix is to add an index to the field or fields used in the query (usually the ID field for a list or the Title field for a library).

When there is an index, that is used to retrieve the item(s); when there is no index the whole list is opened for a scan (and therefore hits the threshold). You create the index on the List (or Library) settings page.

This article is a good overview: http://office.microsoft.com/en-us/sharepoint-foundation-help/manage-lists-and-libraries-with-many-items-HA010377496.aspx

I use

@echo off
Start notepad "filename.txt"
exit

to open the file.

Another example is

@echo off
start chrome "filename.html"
pause

One already exists. If you cannot get over the "Move" syntax of the System.IO namespace. There is a static class FileSystem within the Microsoft.VisualBasic.FileIO namespace that has both a RenameDirectory and RenameFile already within it.

As mentioned by SLaks, this is just a wrapper for Directory.Move and File.Move.

Furthermore, as said in file_put_contents man page in php.net, beware of naming issues.

file_put_contents($dir."/file.txt", "hello");

may not work (even though it is correct on syntax), but

file_put_contents("$dir/file.txt", "hello");

works. I experienced this on different php installed servers.

use this

for num in range(1,100):
    print("\n")

Be careful with rebase. If you're sharing your develop branch with anybody, rebase can make a mess of things. Rebase is good only for your own local branches.

Rule of thumb, if you've pushed the branch to origin, don't use rebase. Instead, use merge.

If you just need a true/false result

bool isInList = intList.IndexOf(intVariable) != -1;

if the intVariable does not exist in the List it will return -1

Well, using LIKE in statement is the best option WHERE datetime LIKE '2009-10-20%' it should work in this case

max-age
    When an intermediate cache is forced, by means of a max-age=0 directive, to revalidate 
its own cache entry, and the client has supplied its own validator in the request, the 
supplied validator might differ from the validator currently stored with the cache entry. 
In this case, the cache MAY use either validator in making its own request without 
affecting semantic transparency. 

    However, the choice of validator might affect performance. The best approach is for the 
intermediate cache to use its own validator when making its request. If the server replies 
with 304 (Not Modified), then the cache can return its now validated copy to the client 
with a 200 (OK) response. If the server replies with a new entity and cache validator, 
however, the intermediate cache can compare the returned validator with the one provided in 
the client's request, using the strong comparison function. If the client's validator is 
equal to the origin server's, then the intermediate cache simply returns 304 (Not 
Modified). Otherwise, it returns the new entity with a 200 (OK) response. 

    If a request includes the no-cache directive, it SHOULD NOT include min-fresh, 
max-stale, or max-age.

Don't accept this as answer - I will have to read it to understand the true usage of it :)

Since TopicService is a Service class, you should annotate it with @Service, so that Spring autowires this bean for you. Like so:

@Service
public class TopicServiceImplementation implements TopicService {
    ...
}

This will solve your problem.

I was looking for same answer and finally I found this link. You can find explained three different ways how to add bootstrap css into your angular 2 project. It helped me.

Here is the link: http://codingthesmartway.com/using-bootstrap-with-angular/

I just had the same issue. In my application I have 2 navigation controllers and pushing the same view controller in each of them worked in one case and not in the other. I mean that when pushing the exact same view controller in the first UINavigationController, viewWillAppear was called but not when pushed in the second navigation controller.

Then I came across this post UINavigationController should call viewWillAppear/viewWillDisappear methods

And realized that my second navigation controller did redefine viewWillAppear. Screening the code showed that I was not calling

[super viewWillAppear:animated];

I added it and it worked !

The documentation says:

If you override this method, you must call super at some point in your implementation.

Something like

file = open('Stud.txt')
contents = file.read()
replaced_contents = contents.replace('A', 'Orange')

<do stuff with the result>

use this way from dotnetperls

  using System;

    class Program

        /// Determines whether the string is a palindrome.
        /// </summary>

        {
            int min = 0;
            int max = value.Length - 1;
            while (true)
            {
                if (min > max)

                "Dammit, I'm mad!",

            foreach (string value in array)
            {

In the source header you can declare:

#!/usr/bin/env python
# -*- coding: utf-8 -*-
....

It is described in the PEP 0263:

Then you can use UTF-8 in strings:

#!/usr/bin/env python
# -*- coding: utf-8 -*-

u = 'idzie waz waska drózka'
uu = u.decode('utf8')
s = uu.encode('cp1250')
print(s)

This declaration is not needed in Python 3 as UTF-8 is the default source encoding (see PEP 3120).

In addition, it may be worth verifying that your text editor properly encodes your code in UTF-8. Otherwise, you may have invisible characters that are not interpreted as UTF-8.

The ifelse function would be a quick and easy way to do this.

I also face the same problem. do the simple steps

1. Go to bin directory copy the path and set it as a environment variable.
2. Run the command prompt as admin and cd to bin directory:
3. Run command : mysqld –install
4. Now the services are successfully installed
5. Start the service in service windows of os
6. Type mysql and go

If it's a DNS problem, you could try:

• ipconfig /flushdns
• ipconfig /registerdns

If this doesn't fix it, you could try editing the hosts file located here:

C:\Windows\System32\drivers\etc\hosts

And ensure that this line (and no other line referencing localhost) is in there:

127.0.0.1 localhost

typedef defines a new data type. So you can have:

typedef char* my_string;
typedef struct{
  int member1;
  int member2;
} my_struct;

So now you can declare variables with these new data types

my_string s;
my_struct x;

s = "welcome";
x.member1 = 10;

For enum, things are a bit different - consider the following examples:

enum Ranks {FIRST, SECOND};
int main()
{
   int data = 20;
   if (data == FIRST)
   {
      //do something
   }
}

using typedef enum creates an alias for a type:

typedef enum Ranks {FIRST, SECOND} Order;
int main()
{
   Order data = (Order)20;  // Must cast to defined type to prevent error

   if (data == FIRST)
   {
      //do something
   }
}

The following code works fine:

@using (Html.BeginForm("Upload", "Upload", FormMethod.Post, 
                                      new { enctype = "multipart/form-data" }))
{
    @Html.ValidationSummary(true)
    <fieldset>
        Select a file <input type="file" name="file" />
        <input type="submit" value="Upload" />
    </fieldset>
}

and generates as expected:

<form action="/Upload/Upload" enctype="multipart/form-data" method="post">    
    <fieldset>
        Select a file <input type="file" name="file" />
        <input type="submit" value="Upload" />
    </fieldset>
</form>

On the other hand if you are writing this code inside the context of other server side construct such as an if or foreach you should remove the @ before the using. For example:

@if (SomeCondition)
{
    using (Html.BeginForm("Upload", "Upload", FormMethod.Post, 
                                      new { enctype = "multipart/form-data" }))
    {
        @Html.ValidationSummary(true)
        <fieldset>
            Select a file <input type="file" name="file" />
            <input type="submit" value="Upload" />
        </fieldset>
    }
}

As far as your server side code is concerned, here's how to proceed:

[HttpPost]
public ActionResult Upload(HttpPostedFileBase file) 
{
    if (file != null && file.ContentLength > 0) 
    {
        var fileName = Path.GetFileName(file.FileName);
        var path = Path.Combine(Server.MapPath("~/content/pics"), fileName);
        file.SaveAs(path);
    }
    return RedirectToAction("Upload");
}

This is an old question, and there are many answers, most of which will be more or less helpful; however, there is one, very important and still relevant point, which none of the answers touch (providing, instead, different hacks to make build possible), and which, I think, in no way has a less importance.. on the contrary.

According to your log message, you are using Maven, which is a Project Management tool, firmly following the conventions, over configuration principle.

When Maven builds the project:

1. it expects your project to have a particular directory structure, so that it knows where to expect what. This is called a Maven's Standard Directory Layout;
2. during the build, it creates also proper directory structure and places files into corresponding locations/directories, and this, in compliance with the Sun Microsystems Directory Structure Standard for Java EE [web] applications.

You may incorporate many things, including maven plugins, changing/reconfiguring project root directory, etc., but better and easier is to follow the default conventions over configuration, according to which, (now is the answer to your problem) there is one simple step that can make your project work: Just place your web.xml under src\main\webapp\WEB-INF\ and try to build the project with mvn package.

This works:

SELECT STR_TO_DATE(dateColumn, '%c/%e/%Y %r') FROM tabbleName WHERE 1

Choose one from, where :my_date is a string input parameter of yyyy-MM-dd format:

SELECT EXTRACT(YEAR FROM CAST(:my_date AS DATE));

or

SELECT DATE_PART('year', CAST(:my_date AS DATE));

Better use CAST than :: as there may be conflicts with input parameters.

This example program illustrates initialization of an array of C strings.

#include <stdio.h>

const char * array[] = {
    "First entry",
    "Second entry",
    "Third entry",
};

#define n_array (sizeof (array) / sizeof (const char *))

int main ()
{
    int i;

    for (i = 0; i < n_array; i++) {
        printf ("%d: %s\n", i, array[i]);
    }
    return 0;
}

It prints out the following:

0: First entry
1: Second entry
2: Third entry

You can access the values in a vector just as you access any other array.

for (int i = 0; i < v.size(); i++)

Usernames and passwords

Subclipse does not collect or store username and password credentials when defining a repository. This is because the JavaHL and SVNKit client adapters are intelligent enough to prompt you for this information when they need to -- including when your password has changed.

You can also allow the adapter to cache this information and a common question is how do you delete this cached information so that you can be prompted again? We have an open request to have an API added to JavaHL so that we could provide a UI to do this. Currently, you have to manually delete the cache. The location of the cache varies based on the client adapter used.

JavaHL caches the information in the same location as the command line client -- in the Subversion runtime configuration area. On Windows this is located in %APPDATA%\Subversion\auth. On Linux and OSX it is located in ~/.subversion/auth. Just find and delete the file with the cached information.

SVNKit caches information in the Eclipse keyring. By default this is a file named .keyring that is stored in the root of the Eclipse configuration folder. Both of these values can be overriden with command line options. To clear the cache, you have to delete the file. Eclipse will create a new empty keyring when you restart

Dan's idea doesn't quite work:

#!/usr/bin/env python
class flushfile(file):
    def __init__(self, f):
        self.f = f
    def write(self, x):
        self.f.write(x)
        self.f.flush()

import sys
sys.stdout = flushfile(sys.stdout)

print "foo"

The result:

Traceback (most recent call last):
  File "./passpersist.py", line 12, in <module>
    print "foo"
ValueError: I/O operation on closed file

I believe the problem is that it inherits from the file class, which actually isn't necessary. According to the docs for sys.stdout:

stdout and stderr needn’t be built-in file objects: any object is acceptable as long as it has a write() method that takes a string argument.

so changing

class flushfile(file):

to

class flushfile(object):

makes it work just fine.

How about using %/sprintf:

i = 20
"%x" % i  #=> "14"

As a follow on, you could select "all nodes with a particular attribute" like this:

//*[@id='4']

Try changing Deny from all to Allow from all in your conf and see if that helps.

Try this

@font-face {  _x000D_
    src: url(fonts/Market_vilis.ttf) format("truetype");_x000D_
}_x000D_
div.FontMarket { _x000D_
    font-family:  Market Deco;_x000D_
}

 <div class="FontMarket">KhonKaen Market</div>

A better and more organized way of overriding Devise controllers and views using namespaces:

Create the following folders:

app/controllers/my_devise
app/views/my_devise

Put all controllers that you want to override into app/controllers/my_devise and add MyDevise namespace to controller class names. Registrations example:

# app/controllers/my_devise/registrations_controller.rb
class MyDevise::RegistrationsController < Devise::RegistrationsController

  ...

  def create
    # add custom create logic here
  end

  ...    

end 

Change your routes accordingly:

devise_for :users,
           :controllers  => {
             :registrations => 'my_devise/registrations',
             # ...
           }

Copy all required views into app/views/my_devise from Devise gem folder or use rails generate devise:views, delete the views you are not overriding and rename devise folder to my_devise.

This way you will have everything neatly organized in two folders.

using indices, for loops and formatting:

import numpy as np

def printMatrix(a):
   print "Matrix["+("%d" %a.shape[0])+"]["+("%d" %a.shape[1])+"]"
   rows = a.shape[0]
   cols = a.shape[1]
   for i in range(0,rows):
      for j in range(0,cols):
         print "%6.f" %a[i,j],
      print
   print      


def printMatrixE(a):
   print "Matrix["+("%d" %a.shape[0])+"]["+("%d" %a.shape[1])+"]"
   rows = a.shape[0]
   cols = a.shape[1]
   for i in range(0,rows):
      for j in range(0,cols):
         print("%6.3f" %a[i,j]),
      print
   print      


inf = float('inf')
A = np.array( [[0,1.,4.,inf,3],
     [1,0,2,inf,4],
     [4,2,0,1,5],
     [inf,inf,1,0,3],
     [3,4,5,3,0]])

printMatrix(A)    
printMatrixE(A)    

which yields the output:

Matrix[5][5]
     0      1      4    inf      3
     1      0      2    inf      4
     4      2      0      1      5
   inf    inf      1      0      3
     3      4      5      3      0

Matrix[5][5]
 0.000  1.000  4.000    inf  3.000
 1.000  0.000  2.000    inf  4.000
 4.000  2.000  0.000  1.000  5.000
   inf    inf  1.000  0.000  3.000
 3.000  4.000  5.000  3.000  0.000

There's no need to group in that subquery... a where clause would suffice:

SELECT * FROM tblpm n
WHERE date_updated=(SELECT MAX(date_updated)
    FROM tblpm WHERE control_number=n.control_number)

Also, do you have an index on the 'date_updated' column? That would certainly help.

In response to @MiniQuark's answer:

I was trying to read in a csv file that was half-French (containing accents) and also some strings which would eventually become integers and floats. As a test, I created a test.txt file that looked like this:

Montréal, über, 12.89, Mère, Françoise, noël, 889

I had to include lines 2 and 3 to get it to work (which I found in a python ticket), as well as incorporate @Jabba's comment:

import sys 
reload(sys) 
sys.setdefaultencoding("utf-8")
import csv
import unicodedata

def remove_accents(input_str):
    nkfd_form = unicodedata.normalize('NFKD', unicode(input_str))
    return u"".join([c for c in nkfd_form if not unicodedata.combining(c)])

with open('test.txt') as f:
    read = csv.reader(f)
    for row in read:
        for element in row:
            print remove_accents(element)

The result:

Montreal
uber
12.89
Mere
Francoise
noel
889

(Note: I am on Mac OS X 10.8.4 and using Python 2.7.3)

Adding a separate answer because it is radically different.

You could use rgba and set the alpha channel low (to get transparency) to make your drop shadow less noticeable.

Try something like this (play with the .5)

-webkit-box-shadow: 0px -4px 7px rbga(230, 230, 230, .5);
-moz-box-shadow: 0px -4px 7px rbga(230, 230, 230, .5);
box-shadow: 0px -4px 7px rbga(230, 230, 230, .5);

Hope this helps!

try this:

.test {
    position:absolute;
    background:blue;
    width:200px;
    height:200px;
    top:40px;
    transition:left 1s linear;
    left: 0;
}

I used following Regex to satisfy for following emails.

[email protected] # Minimum three characters
[email protected] # Accepts Caps as well.
[email protected] # Accepts . before @

Code

<input type="email" pattern="[A-Za-z0-9._%+-]{3,}@[a-zA-Z]{3,}([.]{1}[a-zA-Z]{2,}|[.]{1}[a-zA-Z]{2,}[.]{1}[a-zA-Z]{2,})" />

where date_dt = to_date(to_char(sysdate-1, 'YYYY-MM-DD') || ' 19:16:08', 'YYYY-MM-DD HH24:MI:SS') 

should work.

There is Distinct() method. it should works.

List<long> longs = new List<long> { 1, 2, 3, 4, 3, 2, 5 };
var distinctList = longs.Distinct().ToList();

In Clean Code: A Handbook of Agile Software Craftsmanship there is an explicit recommendation against the usage of this prefix:

You also don't need to prefix member variables with m_ anymore. Your classes and functions should be small enough that you don't need them.

There is also an example (C# code) of this:

Bad practice:

public class Part
{
    private String m_dsc; // The textual description

    void SetName(string name)
    {
        m_dsc = name;
    }
}

Good practice:

public class Part
{
    private String description;

    void SetDescription(string description)
    {
        this.description = description;
    }
}

We count with language constructs to refer to member variables in the case of explicitly ambiguity (i.e., description member and description parameter): this.

Try this

<select class="form-control" name="country_code" value="{{ old('country_code') }}">
   @foreach (\App\SystemCountry::orderBy('country')->get() as $country)
       <option value="{{ $country->country_code }}"
           @if ($country->country_code == "LKA")
             {{'selected="selected"'}}
           @endif
       >
          {{ $country->country }}
       </option>
   @endforeach
</select>

Go to Help=>install new software=>workwith choice kEPLER and

search in the below "type filter text" --------------market,

1. Select and expand general purpose tools and find MPC Marketplace Client
2. Restart After installed..

I hit on the same problem and finally find the working solution.

1. in the string.xml file, define:

   <string name="textWithHtml">The URL link is &lt;a href="http://www.google.com">Google&lt;/a></string>
   

Replace the "<" less than character with HTML escaped character.

2. In Java code:

   String text = v.getContext().getString(R.string.textWithHtml);
   textView.setText(Html.fromHtml(text));
   textView.setMovementMethod(LinkMovementMethod.getInstance());
   

And the TextBox will correctly display the text with clickable anchor link

You use something like

from flask import send_file

@app.route('/get_image')
def get_image():
    if request.args.get('type') == '1':
       filename = 'ok.gif'
    else:
       filename = 'error.gif'
    return send_file(filename, mimetype='image/gif')

to send back ok.gif or error.gif, depending on the type query parameter. See the documentation for the send_file function and the request object for more information.

I got this exception because I was trying to make a Toast popup from a background thread.
Toast needs an Activity to push to the user interface and threads don't have that.
So one workaround is to give the thread a link to the parent Activity and Toast to that.

Put this code in the thread where you want to send a Toast message:

parent.runOnUiThread(new Runnable() {
    public void run() {
        Toast.makeText(parent.getBaseContext(), "Hello", Toast.LENGTH_LONG).show();
    }
});

Keep a link to the parent Activity in the background thread that created this thread. Use parent variable in your thread class:

private static YourActivity parent;

When you create the thread, pass the parent Activity as a parameter through the constructor like this:

public YourBackgroundThread(YourActivity parent) {
    this.parent = parent;
}

Now the background thread can push Toast messages to the screen.

They are HTTP request libraries...

I end up with the same doubt but the table in this post makes me go with isomorphic-fetch. Which is fetch but works with NodeJS.

http://andrewhfarmer.com/ajax-libraries/

The link above is dead The same table is here: https://www.javascriptstuff.com/ajax-libraries/

Or here:

var startDate = moment(startDateVal, "DD.MM.YYYY");//Date format
var endDate = moment(endDateVal, "DD.MM.YYYY");

var isAfter = moment(startDate).isAfter(endDate);

if (isAfter) {
    window.showErrorMessage("Error Message");
    $(elements.endDate).focus();
    return false;
}

Also can be done from the environment variable:

export CURL_CA_BUNDLE=""

The answer is, really, breadth first search (or depth first search, it doesn't really matter). The details lie in the analysis.

Now, how fast is the algorithm?

First, imagine the graph has no cycles. The number of edges is then O(V), the graph is a forest, goal reached.

Now, imagine the graph has cycles, and your searching algorithm will finish and report success in the first of them. The graph is undirected, and therefore, the when the algorithm inspects an edge, there are only two possibilities: Either it has visited the other end of the edge, or it has and then, this edge closes a circle. And once it sees the other vertex of the edge, that vertex is "inspected", so there are only O(V) of these operations. The second case will be reached only once throughout the run of the algorithm.

To set it programmatically in Activity.java:

public void onCreate(Bundle savedInstanceState) {

  super.onCreate(savedInstanceState);

  setTheme(R.style.MyTheme); // (for Custom theme)
  setTheme(android.R.style.Theme_Holo); // (for Android Built In Theme)

  this.setContentView(R.layout.myactivity);

To set in Application scope in Manifest.xml (all activities):

 <application
    android:theme="@android:style/Theme.Holo"
    android:theme="@style/MyTheme">

To set in Activity scope in Manifest.xml (single activity):

  <activity
    android:theme="@android:style/Theme.Holo"
    android:theme="@style/MyTheme">

To build a custom theme, you will have to declare theme in themes.xml file, and set styles in styles.xml file.

Solution:

>>> s = []
>>> p = ['This', 'That', 'There', 'is', 'apple']
>>> [s.append(i.lower()) if not i.islower() else s.append(i) for i in p]
>>> s
>>> ['this', 'that', 'there', 'is','apple']

This solution will create a separate list containing the lowercase items, regardless of their original case. If the original case is upper then the list s will contain lowercase of the respective item in list p. If the original case of the list item is already lowercase in list p then the list s will retain the item's case and keep it in lowercase. Now you can use list s instead of list p.

PizzaChange=float(input("What would you like the new price for all standard pizzas to be? "))      
for i,price in enumerate(PriceList):
  PriceList[i] = PizzaChange + 3*int(i>=7)

If you want to create a tree data structure then first you have to create the treeElement object. If you create the treeElement object, then you can decide how your tree behaves.

To do this following is the TreeElement class:

class TreeElement (object):

def __init__(self):
    self.elementName = None
    self.element = []
    self.previous = None
    self.elementScore = None
    self.elementParent = None
    self.elementPath = []
    self.treeLevel = 0

def goto(self, data):
    for child in range(0, len(self.element)):
        if (self.element[child].elementName == data):
            return self.element[child]

def add(self):

    single_element = TreeElement()
    single_element.elementName = self.elementName
    single_element.previous = self.elementParent
    single_element.elementScore = self.elementScore
    single_element.elementPath = self.elementPath
    single_element.treeLevel = self.treeLevel

    self.element.append(single_element)

    return single_element

Now, we have to use this element to create the tree, I am using A* tree in this example.

# Initialization Function: Called one time when the game starts
def registerInitialState(self, state):
    return;

# GetAction Function: Called with every frame

            astar_queue.sort(key=lambda x: sortByHeuristic(x))

        # Get the first node from the queue
        astar_child_object = astar_queue.pop(0)
        astar_child_state = astar_child_object.elementName

        # get all legal actions for the current node
        current_actions = astar_child_state.getLegalPacmanActions()

        if current_actions:

                # Get the successor of the current node
                next_state = astar_child_state.generatePacmanSuccessor(action)

                if next_state:

                    # evaluate the successor states using scoreEvaluation heuristic
                    element_scored = [(admissibleHeuristic(next_state), action)]

                        astar_tree_level = parent_tree_level.treeLevel + 1
                    else:
                        astar_tree_level += 1

                    # create tree for the finding the data
                    astar_tree.elementName = next_state
                    astar_tree.elementParent = astar_child_state
                    astar_tree.elementScore = element_scored
                    astar_tree.elementPath.append(astar_child_state)
                    astar_tree.treeLevel = astar_tree_level
                    astar_object = astar_tree.add()

                    # If the state exists then add that to the queue
                    astar_queue.append(astar_object)

                else:
                    # Update the value leaf into the queue
                    astar_leaf_state = astar_tree.goto(astar_child_state)
                    astar_leaf_queue.append(astar_leaf_state)

You can add/remove any elements from the object, but make the structure intect.

Make sure that the file name is correct and that the file is actually in the class path. getResourceAsStream() will return null if this is not the case which causes the last line to throw the exception.

If myProp.properties is in the root directory of your project, use /myProp.properties instead.

I have same problem but with different situation. I can compile without any issue with maven in command line (mvn clean install), but in Intellij I always got "java: diamond operator is not supported in -source 1.5" compile error despite I have set the maven-compiler-plugin with java 1.8 in the pom.xml.

It turned out I have remote repository setting in my maven's settings.xml which the project depends on, but Intellij uses his own maven which doesn't have same setting with my local maven.

So my solution was changing the Intellij's maven setting (Settings -> Build, execution, Deployment -> Maven -> Maven home directory) to use the local maven.

@Transactional uses in service layer which is called by using controller layer (@Controller) and service layer call to the DAO layer (@Repository) i.e data base related operation.

@paweloque For Comparing two Map Objects in java, you can add the keys of a map to list and with those 2 lists you can use the methods retainAll() and removeAll() and add them to another common keys list and different keys list. Using the keys of the common list and different list you can iterate through map, using equals you can compare the maps.

The below code will give output like this: Before {zoo=barbar, foo=barbar} After {zoo=barbar, foo=barbar} Equal: Before- barbar After- barbar Equal: Before- barbar After- barbar

        if (map1 != null) 
        {
            Iterator<String> mapIterator = map1.keySet().iterator();
            while (mapIterator.hasNext()) 
            {
                key.add(mapIterator.next());
            }
        }
        return key;
    }
}

Use the Chr or ChrW function, Chr(charNumber).

I think this will do it:

SELECT * FROM MyTable WHERE mydate > now()::date - 365;

Like @zane-hooper, I've had a similar problem on NFS. On parallel / distributed filesystems the lag between you creating a file on one machine and the other machine "seeing" it can be very large, so I could wait up to a full minute after the creation of the file before the while loop exits (and there also is an aftereffect of it "seeing" an already deleted file).

This creates the illusion that the script "doesn't work", while in fact it is the filesystem that is dropping the ball.

This took me a while to figure out, hope it saves somebody some time.

PS This also causes an annoying number of "Stale file handler" errors.

Wikipedia says:

Method overriding, in object oriented programming, is a language feature that allows a subclass or child class to provide a specific implementation of a method that is already provided by one of its superclasses or parent classes.

In detail, when you have an object foo that has a void hello() function:

class foo {
    virtual void hello(); // Code : printf("Hello!");
}

A child of foo, will also have a hello() function:

class bar : foo {
    // no functions in here but yet, you can call
    // bar.hello()
}

However, you may want to print "Hello Bar!" when hello() function is being called from a bar object. You can do this using override

class bar : foo {
    virtual void hello() override; // Code : printf("Hello Bar!");
}

You can use reduce() - A functional way.

words = "apple banana apple strawberry banana lemon"
reduce( lambda d, c: d.update([(c, d.get(c,0)+1)]) or d, words.split(), {})

returns:

{'strawberry': 1, 'lemon': 1, 'apple': 2, 'banana': 2}

If you want to set the active tab by ID instead of index, you can also use the following:

$('#tabs').tabs({ active: $('#tabs ul').index($('#tab-101')) });

From wikipedia Bash

When Bash starts, it executes the commands in a variety of different scripts.

When Bash is invoked as an interactive login shell, it first reads and executes commands from the file /etc/profile, if that file exists. After reading that file, it looks for ~/.bash_profile, ~/.bash_login, and ~/.profile, in that order, and reads and executes commands from the first one that exists and is readable.

When a login shell exits, Bash reads and executes commands from the file ~/.bash_logout, if it exists.

When an interactive shell that is not a login shell is started, Bash reads and executes commands from ~/.bashrc, if that file exists. This may be inhibited by using the --norc option. The --rcfile file option will force Bash to read and execute commands from file instead of ~/.bashrc.

Using HTTP with SSL will make your life much easier and you can rest at ease very smart people (smarter than me at least!) have scrutinized this method of confidential communication for years.

If you're writing a chrome-extension

You have to add in the manifest.json the permissions for your domain(s).

"permissions": [
   "http://example.com/*",
   "https://example.com/*",
   "http://www.example.com/*",
   "https://www.example.com/*"

Thanks to @EdChum I was struggling with same problem especially when indexes do not match. Unfortunatly in pandas guide this case is missed (when you for example delete some rows)

import pandas as pd
t=pd.DataFrame()
t['a']=[1,2,3,4]
t=t.loc[t['a']>1] #now index starts from 1

u=pd.DataFrame()
u['b']=[1,2,3] #index starts from 0

#option 1
#keep index of t
u.index = t.index 

#option 2
#index of t starts from 0
t.reset_index(drop=True, inplace=True)

#now concat will keep number of rows 
r=pd.concat([t,u], axis=1)

The thing is that the printf function needs a pointer as parameter. However a char is a variable that you have directly acces. A string is a pointer on the first char of the string, so you don't have to add the * because * is the identifier for the pointer of a variable.

Basically , For example :

public class Kerem
{
    public static void main(String[] args)
    {
        short x = 10;
        short y = 3;
        Object o = y;
        System.out.println(o.getClass()); // java.lang.Short
    }

}

#case_date= 03/31/2020   

#Above is the value stored in case_date in format(mm/dd/yyyy )

demo=case_date.split("/")
new_case_date = demo[1]+"-"+demo[0]+"-"+demo[2]
#new format of date is (dd/mm/yyyy) test by printing it 
print(new_case_date)

Adding additional information to emboss's answer.

To put it simply, there is an incorrect cert in your certificate chain.

For example, your certificate authority will have most likely given you 3 files.

• your_domain_name.crt
• DigiCertCA.crt # (Or whatever the name of your certificate authority is)
• TrustedRoot.crt

You most likely combined all of these files into one bundle.

-----BEGIN CERTIFICATE----- 
(Your Primary SSL certificate: your_domain_name.crt) 
-----END CERTIFICATE----- 
-----BEGIN CERTIFICATE----- 
(Your Intermediate certificate: DigiCertCA.crt) 
-----END CERTIFICATE----- 
-----BEGIN CERTIFICATE----- 
(Your Root certificate: TrustedRoot.crt) 
-----END CERTIFICATE-----

If you create the bundle, but use an old, or an incorrect version of your Intermediate Cert (DigiCertCA.crt in my example), you will get the exact symptoms you are describing.

• SSL connections appear to work from browser
• SSL connections fail from other clients
• Curl fails with error: "curl: (60) SSL certificate : unable to get local issuer certificate"
• openssl s_client -connect gives error "verify error:num=20:unable to get local issuer certificate"

Redownload all certs from your certificate authority and make a fresh bundle.

constructor(props) {
    super(props);
    this.state = {
      visible: true,
}
}

declare visible false so by default modal / view are hide

example = () => {

 this.setState({ visible: !this.state.visible })

}

**Function call **

{this.state.visible == false ?
        <View>
            <TouchableOpacity
              onPress= {() => this.example()}>   // call function
                          <Text>
                            show view
                          </Text>
            </TouchableOpacity>

</View>
:
 <View>
    <TouchableOpacity
              onPress= {() => this.example()}>
                          <Text>
                            hide view
                          </Text>
            </TouchableOpacity>
</View> 
 }

Just to add to the noise here, you could create an extension method:

public static bool IsWithin(this int value, int minimum, int maximum)
{
    return value >= minimum && value <= maximum;
}

Which would let you do something like...

int val = 15;

bool foo = val.IsWithin(5,20);

That being said, this seems like a silly thing to do when the check itself is only one line.

Logic index:

d<-d[!(d$A=="B" & d$E==0),]

It looks like your Spring component scan Base is missing UserServiceImpl

Projection: what ever typed in select clause i.e, 'column list' or '*' or 'expressions' that becomes under projection.

*selection:*what type of conditions we are applying on that columns i.e, getting the records that comes under selection.

For example:

  SELECT empno,ename,dno,job from Emp 
     WHERE job='CLERK'; 

in the above query the columns "empno,ename,dno,job" those comes under projection, "where job='clerk'" comes under selection

For some reason, the accepted answer worked for me only if being used once on the page, but in my case I was trying to save data on many elements on the page and the data was somehow lost on all except the first element.

As an alternative, I ended up writing the data out to the dom and parsing it back in when needed. Perhaps it's less efficient, but worked well for my purpose because I'm really prototyping data and not writing this for production.

To save the data I used:

$('#myElement').attr('data-key', JSON.stringify(jsonObject));

To then read the data back is the same as the accepted answer, namely:

var getBackMyJSON = $('#myElement').data('key');

Doing it this way also made the data appear in the dom if I were to inspect the element with Chrome's debugger.

If I understand you correctly, you want to list to exclude duplicates on one column only, inner join to a sub-select

select u.* [whatever joined values]
from users u
inner join
(select name from users group by name having count(*)=1) uniquenames
on uniquenames.name = u.name

Another option you can choose:

select price = table1.price , other_price = table2.price from .....

Reference:

In case you are curious about the performance or otherwise of aliasing a column using “=” versus “as”.

Stack memory allocation (function variables, local variables) can be problematic when your stack is too "deep" and you overflow the memory available to stack allocations. The heap is for objects that need to be accessed from multiple threads or throughout the program lifecycle. You can write an entire program without using the heap.

You can leak memory quite easily without a garbage collector, but you can also dictate when objects and memory is freed. I have run in to issues with Java when it runs the GC and I have a real time process, because the GC is an exclusive thread (nothing else can run). So if performance is critical and you can guarantee there are no leaked objects, not using a GC is very helpful. Otherwise it just makes you hate life when your application consumes memory and you have to track down the source of a leak.

If you're executing the query and expecting a ResultSet (you are in this scenario, at least) then you can simply call ResultSet's getStatement() like so:

ResultSet rs = pstmt.executeQuery();
String executedQuery = rs.getStatement().toString();

The variable executedQuery will contain the statement that was used to create the ResultSet.

Now, I realize this question is quite old, but I hope this helps someone..

Use http://www.proxomitron.info and set up the header you want, etc.

Note to Joseph -- if you are creating database objects in a before(:all) they won't be captured in a transaction and you're much more likely to leave cruft in your test database. Use before(:each) instead.

The other reason to use let and its lazy evaluation is so you can take a complicated object and test individual pieces by overriding lets in contexts, as in this very contrived example:

context "foo" do
  let(:params) do
     { :foo => foo,  :bar => "bar" }
  end
  let(:foo) { "foo" }
  it "is set to foo" do
    params[:foo].should eq("foo")
  end
  context "when foo is bar" do
    let(:foo) { "bar" }
    # NOTE we didn't have to redefine params entirely!
    it "is set to bar" do
      params[:foo].should eq("bar")
    end
  end
end

td.setAttribute('rowspan',x);

JS does not have a sleep function, it has setTimeout() or setInterval() functions.

If you can move the code that you need to run after the pause into the setTimeout() callback, you can do something like this:

//code before the pause
setTimeout(function(){
    //do what you need here
}, 2000);

see example here : http://jsfiddle.net/9LZQp/

This won't halt the execution of your script, but due to the fact that setTimeout() is an asynchronous function, this code

console.log("HELLO");
setTimeout(function(){
    console.log("THIS IS");
}, 2000);
console.log("DOG");

will print this in the console:

HELLO
DOG
THIS IS

(note that DOG is printed before THIS IS)

You can use the following code to simulate a sleep for short periods of time:

function sleep(milliseconds) {
  var start = new Date().getTime();
  for (var i = 0; i < 1e7; i++) {
    if ((new Date().getTime() - start) > milliseconds){
      break;
    }
  }
}

now, if you want to sleep for 1 second, just use:

sleep(1000);

example: http://jsfiddle.net/HrJku/1/

please note that this code will keep your script busy for n milliseconds. This will not only stop execution of Javascript on your page, but depending on the browser implementation, may possibly make the page completely unresponsive, and possibly make the entire browser unresponsive. In other words this is almost always the wrong thing to do.

Currently with swift 5 the easiest way to check if the player is playing or paused is to check the .timeControlStatus variable.

player.timeControlStatus == .paused
player.timeControlStatus == .playing

grep's -A 1 option will give you one line after; -B 1 will give you one line before; and -C 1 combines both to give you one line both before and after, -1 does the same.

The block approach avoids running the lookup algorithm for every key:

[dict enumerateKeysAndObjectsUsingBlock:^(id key, id value, BOOL* stop) {
  NSLog(@"%@ => %@", key, value);
}];

Even though NSDictionary is implemented as a hashtable (which means that the cost of looking up an element is O(1)), lookups still slow down your iteration by a constant factor.

My measurements show that for a dictionary d of numbers ...

NSMutableDictionary* dict = [NSMutableDictionary dictionary];
for (int i = 0; i < 5000000; ++i) {
  NSNumber* value = @(i);
  dict[value.stringValue] = value;
}

... summing up the numbers with the block approach ...

__block int sum = 0;
[dict enumerateKeysAndObjectsUsingBlock:^(NSString* key, NSNumber* value, BOOL* stop) {
  sum += value.intValue;
}];

... rather than the loop approach ...

int sum = 0;
for (NSString* key in dict)
  sum += [dict[key] intValue];

... is about 40% faster.

EDIT: The new SDK (6.1+) appears to optimise loop iteration, so the loop approach is now about 20% faster than the block approach, at least for the simple case above.

In the first question, you don't need an event listener on every input that would be wasteful.

Instead, listen for the enter key and to find the currently focused element use document.activeElement

window.onkeypress = function(e) {
    if (e.which == 13) {
       e.preventDefault();
       var nextInput = inputs.get(inputs.index(document.activeElement) + 1);
       if (nextInput) {
          nextInput.focus();
       }
    }
};

One event listener is better than many, especially on low power / mobile browsers.

You can use move for this. The documentation from help move states:

Moves files and renames files and directories.

To move one or more files:
MOVE [/Y | /-Y] [drive:][path]filename1[,...] destination

To rename a directory:
MOVE [/Y | /-Y] [drive:][path]dirname1 dirname2

  [drive:][path]filename1 Specifies the location and name of the file
                          or files you want to move.
  destination             Specifies the new location of the file. Destination
                          can consist of a drive letter and colon, a
                          directory name, or a combination. If you are moving
                          only one file, you can also include a filename if
                          you want to rename the file when you move it.
  [drive:][path]dirname1  Specifies the directory you want to rename.
  dirname2                Specifies the new name of the directory.

  /Y                      Suppresses prompting to confirm you want to
                          overwrite an existing destination file.
  /-Y                     Causes prompting to confirm you want to overwrite
                          an existing destination file.

The switch /Y may be present in the COPYCMD environment variable.
This may be overridden with /-Y on the command line.  Default is
to prompt on overwrites unless MOVE command is being executed from
within a batch script.

See the following transcript for an example where it initially shows the qq1 and qq2 directories as having three and no files respectively. Then, we do the move and we find that the three files have been moved from qq1 to qq2 as expected.

To whoever may be checking this out in 2018. I am using font awesome 4.7.0 and I got this issue solved by simply taking out the s in fas as seen in the code <i class="fa fa-[icon-name]"></i>. This was originally <i class="fas fa-[icon-name]"></i>.

Hope this helps.

Right click on your project -> properties -> build path. Add to your build path jar file(s) that have the javax.servlet implemenation. Ite depends on your servlet container or application server what file(s) you need to include, so search for that information.

You can also use LocalBroadcast for this purpose. Here is a quick guide

Create a broadcast receiver:

   LocalBroadcastManager.getInstance(this).registerReceiver(
            mMessageReceiver, new IntentFilter("speedExceeded"));

private BroadcastReceiver mMessageReceiver = new BroadcastReceiver() {
    @Override
    public void onReceive(Context context, Intent intent) {
        String action = intent.getAction();
        Double currentSpeed = intent.getDoubleExtra("currentSpeed", 20);
        Double currentLatitude = intent.getDoubleExtra("latitude", 0);
        Double currentLongitude = intent.getDoubleExtra("longitude", 0);
        //  ... react to local broadcast message
    }

This is how you can trigger it

Intent intent = new Intent("speedExceeded");
intent.putExtra("currentSpeed", currentSpeed);
intent.putExtra("latitude", latitude);
intent.putExtra("longitude", longitude);
LocalBroadcastManager.getInstance(this).sendBroadcast(intent);

unRegister receiver in onPause:

protected void onPause() {
  super.onPause();
  LocalBroadcastManager.getInstance(this).unregisterReceiver(mMessageReceiver);
}

You're thinking too complicated. It's actually just $('#'+openaddress).

Why "one line"? You can fit anything onto one line.

Assuming you want them to start with 'a', and increment by one character each time (with wrapping > 26), here's a line:

>>> mkstring = lambda(x): "".join(map(chr, (ord('a')+(y%26) for y in range(x))))
>>> mkstring(10)
'abcdefghij'
>>> mkstring(30)
'abcdefghijklmnopqrstuvwxyzabcd'

Something like this should do the trick

function array_max_key($array) {
  $max_key = -1;
  $max_val = -1;

  foreach ($array as $key => $value) {
    if ($value > $max_val) {
      $max_key = $key;
      $max_val = $value;
    }
  }

  return $max_key;
}

FormulaR1C1 has the same behavior as Formula, only using R1C1 style annotation, instead of A1 annotation. In A1 annotation you would use:

Worksheets("Sheet1").Range("A5").Formula = "=A4+A10"

In R1C1 you would use:

Worksheets("Sheet1").Range("A5").FormulaR1C1 = "=R4C1+R10C1"

It doesn't act upon row 1 column 1, it acts upon the targeted cell or range. Column 1 is the same as column A, so R4C1 is the same as A4, R5C2 is B5, and so forth.

The command does not change names, the targeted cell changes. For your R2C3 (also known as C2) example :

Worksheets("Sheet1").Range("C2").FormulaR1C1 = "=your formula here"

A one-liner using only the standard library works starting with Python 3.3. You can get a local timezone aware datetime object using astimezone (as suggested by johnchen902):

from datetime import datetime, timezone

aware_local_now = datetime.now(timezone.utc).astimezone()

print(aware_local_now)
# 2020-03-03 09:51:38.570162+01:00

print(repr(aware_local_now))
# datetime.datetime(2020, 3, 3, 9, 51, 38, 570162, tzinfo=datetime.timezone(datetime.timedelta(0, 3600), 'CET'))

If you are getting an error like the one below:

OperationalError: FATAL:  no pg_hba.conf entry for host "your ipv6",
                  user "username", database "postgres", SSL off

then add an entry like the following, with your mac address.

host   all    all       [your ipv6]/128         md5

try this.

table 
{
    background-color: #aaa;
}

tbody 
{
    background-color: #ddd;
    height: 100px;
    overflow-y: scroll;
    position: absolute;
}

td 
{
    padding: 3px 10px;
    color: green;
    width: 100px;
}

Use ternary operator:

echo (($test == '') ? $redText : '');
echo $test == '' ? $redText : ''; //removed parenthesis

But in this case you can't use shorter reversed version because it will return bool(true) in first condition.

echo (($test != '') ?: $redText); //this will not work properly for this case

I had this problem while trying to mix figures and text. What worked for me was the 'H' option without the '!' option. \begin{figure}[H]
'H' tries to forces the figure to be exactly where you put it in the code. This requires you include \usepackage{float}

The options are explained here

Yes: :has()

Browser support: none

The other methods work fine, but you can also use the good old django.shortcut.redirect.

The code below was taken from this answer.

In Django 2.x:

from django.shortcuts import redirect
from django.urls import path, include

urlpatterns = [
    # this example uses named URL 'hola-home' from app named hola
    # for more redirect's usage options: https://docs.djangoproject.com/en/2.1/topics/http/shortcuts/
    path('', lambda request: redirect('hola/', permanent=True)),
    path('hola/', include('hola.urls')),
]

You are only looking at the first li child in the query you have instead of looking for any li child element that may contain the text, 'Model'. What you need is a query like the following:

//ul[@class='featureList' and ./li[contains(.,'Model')]]

This query will give you the elements that have a class of featureList with one or more li children that contain the text, 'Model'.

C99 does, if you have

#include <stdbool.h> 

If the compiler does not support C99, you can define it yourself:

// file : myboolean.h
#ifndef MYBOOLEAN_H
#define MYBOOLEAN_H

#define false 0
#define true 1
typedef int bool; // or #define bool int

#endif

(but note that this definition changes ABI for bool type so linking against external libraries which were compiled with properly defined bool may cause hard-to-diagnose runtime errors).

var iDiv = document.createElement('div'),
    jDiv = document.createElement('div');
iDiv.id = 'block';
iDiv.className = 'block';
jDiv.className = 'block-2';
iDiv.appendChild(jDiv);
document.getElementsByTagName('body')[0].appendChild(iDiv);

MySQL will assume the part before the equals references the columns named in the INSERT INTO clause, and the second part references the SELECT columns.

INSERT INTO lee(exp_id, created_by, location, animal, starttime, endtime, entct, 
                inact, inadur, inadist, 
                smlct, smldur, smldist, 
                larct, lardur, lardist, 
                emptyct, emptydur)
SELECT id, uid, t.location, t.animal, t.starttime, t.endtime, t.entct, 
       t.inact, t.inadur, t.inadist, 
       t.smlct, t.smldur, t.smldist, 
       t.larct, t.lardur, t.lardist, 
       t.emptyct, t.emptydur 
FROM tmp t WHERE uid=x
ON DUPLICATE KEY UPDATE entct=t.entct, inact=t.inact, ...

If notepad is already started, you should write:

// import the function in your class
[DllImport ("User32.dll")]
static extern int SetForegroundWindow(IntPtr point);

//...

Process p = Process.GetProcessesByName("notepad").FirstOrDefault();
if (p != null)
{
    IntPtr h = p.MainWindowHandle;
    SetForegroundWindow(h);
    SendKeys.SendWait("k");
}

GetProcessesByName returns an array of processes, so you should get the first one (or find the one you want).

If you want to start notepad and send the key, you should write:

Process p = Process.Start("notepad.exe");
p.WaitForInputIdle();
IntPtr h = p.MainWindowHandle;
SetForegroundWindow(h);
SendKeys.SendWait("k");

The only situation in which the code may not work is when notepad is started as Administrator and your application is not.

By doing a rotation of the string you can reverse the order of the words without reversing the order of the letters.

As each word is rotated to the end of the string we reduce the amount of the string to be rotated by the length of the word. We then rotate any spaces to in front of the word we just placed at the end and shorten the rotating part of the string by 1 for each space. If the entire string is rotated with out seeing a space we are done.

Here is am implementation in C+. The l variable contains the length of the buf to rotate, and n counts the number of rotations made.

    #include <stdio.h>
    #include <string.h>
    
    int main(char *argv[], int argc)
    {
      char buf[20] = "My name is X Y Z";
      int l = strlen(buf);
      int n = 1;
    
      while (l >= n) {
        unsigned char c = buf[0];
        for (int i = 1; i < l; i++) {
          buf[i-1] = buf[i];
        }
        buf[l - 1] = c;
        if (buf[0] == ' ' || c == ' ') {
          l -= n;
          n = 1;
        } else {
          n++;
        }
      }
    
      printf("%s\n", buf);
    }

The rotation code was purposely left very simple.

It has been quite a while since this question was asked, and in the meantime, another library that can handle this has cropped up: You can use the copy function included in the Plumbum library:

import plumbum
r = plumbum.machines.SshMachine("example.net")
   # this will use your ssh config as `ssh` from shell
   # depending on your config, you might also need additional
   # params, eg: `user="username", keyfile=".ssh/some_key"`
fro = plumbum.local.path("some_file")
to = r.path("/path/to/destination/")
plumbum.path.utils.copy(fro, to)

as KingCrunch pointed out, using phpinfo you can see what config file is in action in the "Loaded Configuration File" row. in my case in was in C:\xampp\apache\bin note that there is a php.ini also in C:\xampp\php which seems to be redundant and irrelevant

If you are using Google App Engine or MongoDB as your backend, and you are using the djangoappengine library, there is a built in ListField that does exactly what you want. Further, it's easy to query the Listfield to find all objects that contain an element in the list.

One problem with option 1 in answer from Victor Zamanian is that if the type isn't exported then users of your package can't declare it as the type for function parameters etc. One way around this would be to export an interface instead of the struct e.g.

package candidate
// Exporting interface instead of struct
type Candidate interface {}
// Struct is not exported
type candidate struct {
    Name string
    Votes uint32 // Defaults to 0
}
// We are forced to call the constructor to get an instance of candidate
func New(name string) Candidate {
    return candidate{name, 0}  // enforce the default value here
}

Which lets us declare function parameter types using the exported Candidate interface. The only disadvantage I can see from this solution is that all our methods need to be declared in the interface definition, but you could argue that that is good practice anyway.

A simple solution is to set the spring bean in the Job Data Map and then retrieve the bean in the job class, for instance

// the class sets the configures the MyJob class 
    SchedulerFactory sf = new StdSchedulerFactory();
    Scheduler sched = sf.getScheduler();
    Date startTime = DateBuilder.nextGivenSecondDate(null, 15);
    JobDetail job = newJob(MyJob.class).withIdentity("job1", "group1").build();
    job.getJobDataMap().put("processDataDAO", processDataDAO);

`

 // this is MyJob Class
    ProcessDataDAO processDataDAO = (ProcessDataDAO) jec.getMergedJobDataMap().get("processDataDAO");

Or you can try something like this:

Html.DropDownList("Types", Model.Types, new { @readonly = "true" })

Was facing similar issue and found below link more helpful then the answers provided here. I guess this is due to the updates to AWS CLI since the answers are provided.

https://serverfault.com/questions/792937/the-config-profile-adminuser-could-not-be-found

Essentially it helps to create two different files (i.e. one for the general config related information and the second for the credentials related information).

Windows uses carriage return + line feed for newline:

\r\n

Unix only uses Line feed for newline:

\n

In conclusion, simply replace every occurence of \n by \r\n.
Both unix2dos and dos2unix are not by default available on Mac OSX.
Fortunately, you can simply use Perl or sed to do the job:

sed -e 's/$/\r/' inputfile > outputfile                # UNIX to DOS  (adding CRs)
sed -e 's/\r$//' inputfile > outputfile                # DOS  to UNIX (removing CRs)
perl -pe 's/\r\n|\n|\r/\r\n/g' inputfile > outputfile  # Convert to DOS
perl -pe 's/\r\n|\n|\r/\n/g'   inputfile > outputfile  # Convert to UNIX
perl -pe 's/\r\n|\n|\r/\r/g'   inputfile > outputfile  # Convert to old Mac

Just for the fun of it, another way without using any extra variable would be:

var arr = [1, 2, 3, 4, 5, 6, 7, 8, 9];_x000D_
_x000D_
// swap index 0 and 2_x000D_
arr[arr.length] = arr[0];   // copy idx1 to the end of the array_x000D_
arr[0] = arr[2];            // copy idx2 to idx1_x000D_
arr[2] = arr[arr.length-1]; // copy idx1 to idx2_x000D_
arr.length--;               // remove idx1 (was added to the end of the array)_x000D_
_x000D_
_x000D_
console.log( arr ); // -> [3, 2, 1, 4, 5, 6, 7, 8, 9]

I'm using Xcode 8.3/Swift 3

I used @Ron B.'s answer to go through all the code and comment out different functions until I got a successful build. It turns out it was async trailing closures that was causing my error:

My trailing closures:

let firstTask = DispatchWorkItem{
     //self.doSomthing()
}
let secondTask = DispatchWorkItem{
     //self.doSomthingElse()
}

//trailing closure #1
DispatchQueue.main.asyncAfter(deadline: .now() + 10){firstTask}

//trailing closure #2 
DispatchQueue.main.asyncAfter(deadline: .now() + 20){secondTask}

Once I used the autocomplete syntax the Segmentation fault: 11 was Gone

//autocomplete syntax closure #1
DispatchQueue.main.asyncAfter(deadline: .now() + 10, execute: firstTask)

//autocomplete syntax closure #2
DispatchQueue.main.asyncAfter(deadline: .now() + 20, execute: secondTask)

Object Orientation is not about inheritance, it is about encapsulation. And inheritance breaks encapsulation.

Declaring a class final makes perfect sense in a lot of cases. Any object representing a “value” like a color or an amount of money could be final. They stand on their own.

If you are writing libraries, make your classes final unless you explicitly indent them to be derived. Otherwise, people may derive your classes and override methods, breaking your assumptions / invariants. This may have security implications as well.

Joshua Bloch in “Effective Java” recommends designing explicitly for inheritance or prohibiting it and he notes that designing for inheritance is not that easy.

To access named elements placed in a form, it is a good practice to use the form object itself.

To access an arbitrary element in the DOM tree that may on occasion be found within a form, use getElementById and the element's id.

Using FormData is the way to go as indicated by many answers. here is a bit of code that works great for this purpose. I also agree with the comment of nesting ajax blocks to complete complex circumstances. By including e.PreventDefault(); in my experience makes the code more cross browser compatible.

    $('#UploadB1').click(function(e){        
    e.preventDefault();

    if (!fileupload.valid()) {
        return false;            
    }

    var myformData = new FormData();        
    myformData.append('file', $('#uploadFile')[0].files[0]);

    $("#UpdateMessage5").html("Uploading file ....");
    $("#UpdateMessage5").css("background","url(../include/images/loaderIcon.gif) no-repeat right");

    myformData.append('mode', 'fileUpload');
    myformData.append('myid', $('#myid').val());
    myformData.append('type', $('#fileType').val());
    //formData.append('myfile', file, file.name); 

    $.ajax({
        url: 'include/fetch.php',
        method: 'post',
        processData: false,
        contentType: false,
        cache: false,
        data: myformData,
        enctype: 'multipart/form-data',
        success: function(response){
            $("#UpdateMessage5").html(response); //.delay(2000).hide(1); 
            $("#UpdateMessage5").css("background","");

            console.log("file successfully submitted");
        },error: function(){
            console.log("not okay");
        }
    });
});

You can use @@trancount in MSSQL

From the documentation:

Returns the number of BEGIN TRANSACTION statements that have occurred on the current connection.
