Java class final and method final -> sealed. Java member variable final -> readonly for runtime constant, const for compile time constant.

No equivalent for Local Variable final and method argument final

You could achieve that simply by wrapping the image by a <div> and adding overflow: hidden to that element:

<div class="img-wrapper">
    <img src="..." />
</div>

.img-wrapper {
    display: inline-block; /* change the default display type to inline-block */
    overflow: hidden;      /* hide the overflow */
}

WORKING DEMO.

Also it's worth noting that <img> element (like the other inline elements) sits on its baseline by default. And there would be a 4~5px gap at the bottom of the image.

That vertical gap belongs to the reserved space of descenders like: g j p q y. You could fix the alignment issue by adding vertical-align property to the image with a value other than baseline.

Additionally for a better user experience, you could add transition to the images.

Thus we'll end up with the following:

.img-wrapper img {
    transition: all .2s ease;
    vertical-align: middle;
}

UPDATED DEMO.

According to your question...

How to pass parameters to Thread.ThreadStart() method in C#?

...and the error you encountered, you would have to correct your code from

Thread thread = new Thread(new ThreadStart(download(filename));

to

Thread thread = new Thread(new ThreadStart(download));
thread.Start(filename);

However, the question is more complex as it seems at first.

The Thread class currently (4.7.2) provides several constructors and a Start method with overloads.

These relevant constructors for this question are:

public Thread(ThreadStart start);

and

public Thread(ParameterizedThreadStart start);

which either take a ThreadStart delegate or a ParameterizedThreadStart delegate.

The corresponding delegates look like this:

public delegate void ThreadStart();
public delegate void ParameterizedThreadStart(object obj);

So as can be seen, the correct constructor to use seems to be the one taking a ParameterizedThreadStart delegate so that some method conform to the specified signature of the delegate can be started by the thread.

A simple example for instanciating the Thread class would be

Thread thread = new Thread(new ParameterizedThreadStart(Work));

or just

Thread thread = new Thread(Work);

The signature of the corresponding method (called Work in this example) looks like this:

private void Work(object data)
{
   ...
}

What is left is to start the thread. This is done by using either

public void Start();

or

public void Start(object parameter);

While Start() would start the thread and pass null as data to the method, Start(...) can be used to pass anything into the Work method of the thread.

There is however one big problem with this approach: Everything passed into the Work method is cast into an object. That means within the Work method it has to be cast to the original type again like in the following example:

public static void Main(string[] args)
{
    Thread thread = new Thread(Work);

    thread.Start("I've got some text");
    Console.ReadLine();
}

private static void Work(object data)
{
    string message = (string)data; // Wow, this is ugly

    Console.WriteLine($"I, the thread write: {message}");
}

Casting is something you typically do not want to do.

What if someone passes something else which is not a string? As this seems not possible at first (because It is my method, I know what I do or The method is private, how should someone ever be able to pass anything to it?) you may possibly end up with exactly that case for various reasons. As some cases may not be a problem, others are. In such cases you will probably end up with an InvalidCastException which you probably will not notice because it simply terminates the thread.

As a solution you would expect to get a generic ParameterizedThreadStart delegate like ParameterizedThreadStart<T> where T would be the type of data you want to pass into the Work method. Unfortunately something like this does not exist (yet?).

There is however a suggested solution to this issue. It involves creating a class which contains both, the data to be passed to the thread as well as the method that represents the worker method like this:

public class ThreadWithState
{
    private string message;

    public ThreadWithState(string message)
    {
        this.message = message;
    }

    public void Work()
    {
        Console.WriteLine($"I, the thread write: {this.message}");
    }
}

With this approach you would start the thread like this:

ThreadWithState tws = new ThreadWithState("I've got some text");
Thread thread = new Thread(tws.Work);

thread.Start();

So in this way you simply avoid casting around and have a typesafe way of providing data to a thread ;-)

It basically means that the application wants to perform some "naming operations" (e.g. JNDI or LDAP lookups), and it didn't have sufficient information available to be able to create a connection to the directory server. As the docs for the exception state,

This exception is thrown when no initial context implementation can be created. The policy of how an initial context implementation is selected is described in the documentation of the InitialContext class.

And if you dutifully have a look at the javadocs for InitialContext, they describe quite well how the initial context is constructed, and what your options are for supplying the address/credentials/etc.

If you have a go at creating the context and get stuck somewhere else, please post back explaining what you've done so far and where you're running aground.

This should work...

var displayDate = new Date().toLocaleDateString();

alert(displayDate);

But I suspect you are trying it on something else, for example:

var displayDate = Date.now.toLocaleDateString(); // No!

alert(displayDate);

I would like to share this answer I found because the cause of the problem was not the firewall or the process not listening correctly, it was the code sample provided from Microsoft that I used.

https://msdn.microsoft.com/en-us/library/system.net.sockets.socket%28v=vs.110%29.aspx

I implemented this function almost exactly as written, but what happened is I got this error:

2016-01-05 12:00:48,075 [10] ERROR - The error is: System.Net.Sockets.SocketException (0x80004005): No connection could be made because the target machine actively refused it [fe80::caa:745:a1da:e6f1%11]:4080

This code would say the socket is connected, but not under the correct IP address actually needed for proper communication. (Provided by Microsoft)

private static Socket ConnectSocket(string server, int port)
    {
        Socket s = null;
        IPHostEntry hostEntry = null;

        // Get host related information.
        hostEntry = Dns.GetHostEntry(server);

        // Loop through the AddressList to obtain the supported AddressFamily. This is to avoid
        // an exception that occurs when the host IP Address is not compatible with the address family
        // (typical in the IPv6 case).
        foreach(IPAddress address in hostEntry.AddressList)
        {
            IPEndPoint ipe = new IPEndPoint(address, port);
            Socket tempSocket = 
                new Socket(ipe.AddressFamily, SocketType.Stream, ProtocolType.Tcp);

            tempSocket.Connect(ipe);

            if(tempSocket.Connected)
            {
                s = tempSocket;
                break;
            }
            else
            {
                continue;
            }
        }
        return s;
    }

I re-wrote the code to just use the first valid IP it finds. I am only concerned with IPV4 using this, but it works with localhost, 127.0.0.1, and the actually IP address of you network card, where the example provided by Microsoft failed!

    private Socket ConnectSocket(string server, int port)
    {
        Socket s = null;

        try
        {
            // Get host related information.
            IPAddress[] ips;
            ips = Dns.GetHostAddresses(server);

            Socket tempSocket = null;
            IPEndPoint ipe = null;

            ipe = new IPEndPoint((IPAddress)ips.GetValue(0), port);
            tempSocket = new Socket(ipe.AddressFamily, SocketType.Stream, ProtocolType.Tcp);

            Platform.Log(LogLevel.Info, "Attempting socket connection to " + ips.GetValue(0).ToString() + " on port " + port.ToString());
            tempSocket.Connect(ipe);

            if (tempSocket.Connected)
            {
                s = tempSocket;
                s.SendTimeout = Coordinate.HL7SendTimeout;
                s.ReceiveTimeout = Coordinate.HL7ReceiveTimeout;
            }
            else
            {
                return null;
            }

            return s;
        }
        catch (Exception e)
        {
            Platform.Log(LogLevel.Error, "Error creating socket connection to " + server + " on port " + port.ToString());
            Platform.Log(LogLevel.Error, "The error is: " + e.ToString());
            if (g_NoOutputForThreading == false)
                rtbResponse.AppendText("Error creating socket connection to " + server + " on port " + port.ToString());
            return null;
        }
    }

throw is for rethrowing a caught exception. This can be useful if you want to do something with the exception before passing it up the call chain.

Using throw without any arguments preserves the call stack for debugging purposes.

Use the below code to resolve the issue.

import json
from numpyencoder import NumpyEncoder
alerts = {'upper':[1425],'lower':[576],'level':[2],'datetime':['2012-08-08 
15:30']}
afile = open('test.json','w')
afile.write(json.dumps(alerts,encoding='UTF-8',cls=NumpyEncoder))
afile.close()

You can also use that:

client.Headers.Add(HttpRequestHeader.UserAgent, "My app.");

May be you are trying to attach a function when table rows are clicked.

var table = document.getElementById("tableId");
var rows = table.getElementsByTagName("tr");
for (i = 0; i < rows.length; i++) {
    rows[i].onclick = functioname(); //call the function like this
}

There is a typo error :

$('#activelist :checkbox')...

Should be :

$('#inactivelist:checkbox')...

<%
String session_val = (String)session.getAttribute("sessionval"); 
System.out.println("session_val"+session_val);
%>
<html>
<head>
<script type="text/javascript">
var session_obj= '<%=session_val%>';
alert("session_obj"+session_obj);
</script>
</head>
</html>

On Mac using brew is a better option as apt-get is not available. Command:

brew install python

In case you have both python2 & python3 installed on machine

python2.7 -m ensurepip --default-pip

simply should solve the issue.

If instead you are missing pip from python 3 then simply change python2.7 to python3 in the command above.

They use regular CSS.

Just use your regular font family like this:

font-family: 'Open Sans', sans-serif;

Now you decide what "weight" the font should have by adding

for semi-bold

font-weight:600;

for bold (700)

font-weight:bold;

for extra bold (800)

font-weight:800;

Like this its fallback proof, so if the google font should "fail" your backup font Arial/Helvetica(Sans-serif) use the same weight as the google font.

Pretty smart :-)

Note that the different font weights have to be specifically imported via the link tag url (family query param of the google font url) in the header.

For example the following link will include both weights 400 and 700:

<link href='fonts.googleapis.com/css?family=Comfortaa:400,700'; rel='stylesheet' type='text/css'>

I ended up installing a new copy of Eclipse - JAVA EE, and it all works now.

To add on to what Alisson said you could check to see if a row is returned.

// Query stuff ...
$query = $this->db->get();

if ($query->num_rows() > 0)
{
    $row = $query->row(); 
    return $row->campaign_id;
}

return null; // or whatever value you want to return for no rows found

You can pre-fetch your data by using Resolvers in Angular2+, Resolvers process your data before your Component fully be loaded.

There are many cases that you want to load your component only if there is certain thing happening, for example navigate to Dashboard only if the person already logged in, in this case Resolvers are so handy.

Look at the simple diagram I created for you for one of the way you can use the resolver to send the data to your component.

Applying Resolver to your code is pretty simple, I created the snippets for you to see how the Resolver can be created:

import { Injectable } from '@angular/core';
import { Router, Resolve, RouterStateSnapshot, ActivatedRouteSnapshot } from '@angular/router';
import { MyData, MyService } from './my.service';

@Injectable()
export class MyResolver implements Resolve<MyData> {
  constructor(private ms: MyService, private router: Router) {}

  resolve(route: ActivatedRouteSnapshot, state: RouterStateSnapshot): Promise<MyData> {
    let id = route.params['id'];

    return this.ms.getId(id).then(data => {
      if (data) {
        return data;
      } else {
        this.router.navigate(['/login']);
        return;
      }
    });
  }
}

and in the module:

import { MyResolver } from './my-resolver.service';

@NgModule({
  imports: [
    RouterModule.forChild(myRoutes)
  ],
  exports: [
    RouterModule
  ],
  providers: [
    MyResolver
  ]
})
export class MyModule { }

and you can access it in your Component like this:

/////
 ngOnInit() {
    this.route.data
      .subscribe((data: { mydata: myData }) => {
        this.id = data.mydata.id;
      });
  }
/////

And in the Route something like this (usually in the app.routing.ts file):

////
{path: 'yourpath/:id', component: YourComponent, resolve: { myData: MyResolver}}
////

If you like Python and have obtained a legacy API token from the slack api, you can delete all private messages you sent to a user with the following:

import requests
import sys
import time
from json import loads

# config - replace the bit between quotes with your "token"
token = 'xoxp-854385385283-5438342854238520-513620305190-505dbc3e1c83b6729e198b52f128ad69'

# replace 'Carl' with name of the person you were messaging
dm_name = 'Carl'

# helper methods
api = 'https://slack.com/api/'
suffix = 'token={0}&pretty=1'.format(token)

def fetch(route, args=''):
  '''Make a GET request for data at `url` and return formatted JSON'''
  url = api + route + '?' + suffix + '&' + args
  return loads(requests.get(url).text)

# find the user whose dm messages should be removed
target_user = [i for i in fetch('users.list')['members'] if dm_name in i['real_name']]
if not target_user:
  print(' ! your target user could not be found')
  sys.exit()

# find the channel with messages to the target user
channel = [i for i in fetch('im.list')['ims'] if i['user'] == target_user[0]['id']]
if not channel:
  print(' ! your target channel could not be found')
  sys.exit()

# fetch and delete all messages
print(' * querying for channel', channel[0]['id'], 'with target user', target_user[0]['id'])
args = 'channel=' + channel[0]['id'] + '&limit=100'
result = fetch('conversations.history', args=args)
messages = result['messages']
print(' * has more:', result['has_more'], result.get('response_metadata', {}).get('next_cursor', ''))
while result['has_more']:
  cursor = result['response_metadata']['next_cursor']
  result = fetch('conversations.history', args=args + '&cursor=' + cursor)
  messages += result['messages']
  print(' * next page has more:', result['has_more'])

for idx, i in enumerate(messages):
  # tier 3 method rate limit: https://api.slack.com/methods/chat.delete
  # all rate limits: https://api.slack.com/docs/rate-limits#tiers
  time.sleep(1.05)
  result = fetch('chat.delete', args='channel={0}&ts={1}'.format(channel[0]['id'], i['ts']))
  print(' * deleted', idx+1, 'of', len(messages), 'messages', i['text'])
  if result.get('error', '') == 'ratelimited':
    print('\n ! sorry there have been too many requests. Please wait a little bit and try again.')
    sys.exit()

None of the above solutions are going to work.

Try this:

function filter_html($value){
    $value = mb_convert_encoding($value, 'ISO-8859-1', 'UTF-8');
    return $value;
}

I'm posting this here as I am sure more people will be comeing across this issue. I installed Security Update for microsoft Visual Studio 2010 Service Pack 1 (KB2565057) and lost Intellisense in SQL Server Management studio 2008 (not R2).

An uninstall of the SP restored Intellisense .. Don't you just love Microsoft????

1. First try npm install ,if the issue is not yet fixed try the following one after the other.
2. npm cache clean ,then
3. npm install -g npm,then npm install,Finally
4. ng serve --o to run the project. Hope this will help....

Cron jobs usually are stored in a per-user file under /var/spool/cron

The simplest thing for you to do is probably just create a text file with the job configured, then copy it to the cron spool folder and make sure it has the right permissions (600).

Using DataBinding and setting background to the edittext with resources from the drawable folder causes the exception.

<EditText

                            android:fontFamily="@font/avenir_roman"/>

Solution

I just change the background from android:background="@drawable/rectangle" to android:background="@null"

Clean and Rebuild the Project.

A great Spring MVC quickstart archetype is available on GitHub, courtesy of kolorobot. Good instructions are provided on how to install it to your local Maven repo and use it to create a new Spring MVC project. He’s even helpfully included the Tomcat 7 Maven plugin in the archetypical project so that the newly created Spring MVC can be run from the command line without having to manually deploy it to an application server.

Kolorobot’s example application includes the following:

• No-xml Spring MVC 3.2 web application for Servlet 3.0 environment
• Apache Tiles with configuration in place,
• Bootstrap
• JPA 2.0 (Hibernate/HSQLDB)
• JUnit/Mockito
• Spring Security 3.1

Microsoft also release the Microsoft Visual Studio 2015 Installer Projects Extension This is the same extension as the 2013 version but for Visual Studio 2015

Try this

plt.imshow(im.reshape(im.shape[0], im.shape[1]), cmap=plt.cm.Greys)

It would help in some cases.

import re
re.sub('<.*?>', '', string)
"i think mabe 124 + but I don't have a big experience it just how I see it in my eyes fun stuff"

The re.sub function takes a regular expresion and replace all the matches in the string with the second parameter. In this case, we are searching for all tags ('<.*?>') and replacing them with nothing ('').

The ? is used in re for non-greedy searches.

More about the re module.

From within less (in Linux):

 g and the line number to go forward

 G and the line number to go backwards

Used alone, g and G will take you to the first and last line in a file respectively; used with a number they are both equivalent.

An example; you want to go to line 320123 of a file,

press 'g' and after the colon type in the number 320123

Additionally you can type '-N' inside less to activate / deactivate the line numbers. You can as a matter of fact pass any command line switches from inside the program, such as -j or -N.

NOTE: You can provide the line number in the command line to start less (less +number -N) which will be much faster than doing it from inside the program:

less +12345 -N /var/log/hugelogfile

This will open a file displaying the line numbers and starting at line 12345

For those who are building an ASP.NET MVC project, make sure that you add the:

<meta http-equiv="X-UA-Compatible" content="IE=edge">

tag into your Layout (template) page. I just spent two hours debugging and tweaking, only to realize that I had only added that meta tag into my child pages. As soon as I added it to my layout page, the browser loaded in EDGE mode perfectly.

Try this:

SELECT DISTINCT city FROM STATION WHERE ID%2=0 ORDER BY CITY;

$("div.test:not(:first)").hide();

or:

$("div.test:not(:eq(0))").hide();

or:

$("div.test").not(":eq(0)").hide();

or:

$("div.test:gt(0)").hide();

or: (as per @Jordan Lev's comment):

$("div.test").slice(1).hide();

and so on.

After years and years, python finally agreed for a binary disribution called wheel which allows to install even binary extensions on Windows without having a compiler with simple pip install packagename. There is a list of popular packages with their status. Pycrypto is not there yet, but lxml, PySide and Scrapy for example.

Edited Nov 2015: pip uninstall pycrypto & pip install pycryptodome. It is a pycrypto fork with new features and it supports wheel. It replaces pycrypto, so existing code will continue to work (see https://pycryptodome.readthedocs.org/en/latest/src/examples.html)

Shahar's answer was really helpful, but I found it quite tedious to do this all myself, so I made a nifty little Python program:

import re
import urllib2
import string
url1 = raw_input("Please enter a URL from Tunein Radio: ");
open_file = urllib2.urlopen(url1);
raw_file = open_file.read();
API_key = re.findall(r"StreamUrl\":\"(.*?),",raw_file);
#print API_key;
#print "The API key is: " + API_key[0];
use_key = urllib2.urlopen(str(API_key[0]));
key_content = use_key.read();
raw_stream_url = re.findall(r"Url\": \"(.*?)\"",key_content);
bandwidth = re.findall(r"Bandwidth\":(.*?),", key_content);
reliability = re.findall(r"lity\":(.*?),", key_content);
isPlaylist = re.findall(r"HasPlaylist\":(.*?),",key_content);
codec = re.findall(r"MediaType\": \"(.*?)\",", key_content);
tipe = re.findall(r"Type\": \"(.*?)\"", key_content);
total = 0
for element in raw_stream_url:
    total = total + 1
i = 0
print "I found " + str(total) + " streams.";
for element in raw_stream_url:
    print "Stream #" + str(i + 1);
    print "Stream stats:";
    print "Bandwidth: " + str(bandwidth[i]) + " kilobytes per second."
    print "Reliability: " + str(reliability[i]) + "%"
    print "HasPlaylist: " + str(isPlaylist[i]) + "."
    print "Stream codec: " + str(codec[i]) + "."
    print "This audio stream is " + tipe[i].lower() + "."
    print "Pure streaming URL: " + str(raw_stream_url[i]) + ".";
    i = i + 1
raw_input("Press enter to close TMUS.")

It's basically Shahar's solution automated.

Hash === @some_var #=> return Boolean

this can also be used with case statement

case @some_var
when Hash
   ...
when Array
   ...
end

Your interior <div> elements should likely both be float:left. Divs size to 100% the size of their container width automatically. Try using display:inline-block instead of width:auto on the container div. Or possibly float:left the container and also apply overflow:auto. Depends on what you're after exactly.

Obligatory jQuery solution. Finds and sets the title attribute to foo. Note this selects a single element since I'm doing it by id, but you could easily set the same attribute on a collection by changing the selector.

$('#element').attr( 'title', 'foo' );

Also, It can be done with LINQ

var str = "Hello@Hello&Hello(Hello)";
var characters = str.Select(c => char.IsLetter(c) ? c : ',')).ToArray();             
var output = new string(characters);
Console.WriteLine(output);

This question is confusing. A regular object, {} doesn't have a length property unless you're intending to make your own function constructor which generates custom objects which do have it ( in which case you didn't specify ).

Meaning, you have to get the "length" by a for..in statement on the object, since length is not set, and increment a counter.

I'm confused as to why you need the length. Are you manually setting 0 on the object, or are you relying on custom string keys? eg obj['foo'] = 'bar';. If the latter, again, why the need for length?

Edit #1: Why can't you just do this?

list = [ {name:'john'}, {name:'bob'} ];

Then iterate over list? The length is already set.

In Ubuntu In the conf file: /etc/apache2/sites-enabled/your-file.conf

change

AddHandler application/x-httpd-php .js .xml .htc .css

to:

AddHandler application/x-httpd-php .js .xml .htc

Just for the future reference, you just need to add System.Configuration to your references library:

On the same note, if your server supports both http and https you can connect using:

var socket = io.connect('//localhost');

to auto detect the browser scheme and connect using http/https accordingly. when in https, the transport will be secured by default, as connecting using

var socket = io.connect('https://localhost');

will use secure web sockets - wss:// (the {secure: true} is redundant).

for more information on how to serve both http and https easily using the same node server check out this answer.

1. Set var step=1 as global variable by putting it above the function call
2. put semicolons

It will look like this

<head>
<script type="text/javascript">
var image1 = new Image()
image1.src = "images/pentagg.jpg"
var image2 = new Image()
image2.src = "images/promo.jpg"
</script>
</head>
<body>
<p><img src="images/pentagg.jpg" width="500" height="300" name="slide" /></p>
<script type="text/javascript">
        var step=1;
        function slideit()
        {
            document.images.slide.src = eval("image"+step+".src");
            if(step<2)
                step++;
            else
                step=1;
            setTimeout("slideit()",2500);
        }
        slideit();
</script>
</body>

It's compiler dependent. That said, in general using " prioritizes headers in the current working directory over system headers. <> usually is used for system headers. From to the specification (Section 6.10.2):

A preprocessing directive of the form

  # include <h-char-sequence> new-line

searches a sequence of implementation-defined places for a header identified uniquely by the specified sequence between the < and > delimiters, and causes the replacement of that directive by the entire contents of the header. How the places are specified or the header identified is implementation-defined.

A preprocessing directive of the form

  # include "q-char-sequence" new-line

causes the replacement of that directive by the entire contents of the source file identified by the specified sequence between the " delimiters. The named source file is searched for in an implementation-defined manner. If this search is not supported, or if the search fails, the directive is reprocessed as if it read

  # include <h-char-sequence> new-line

with the identical contained sequence (including > characters, if any) from the original directive.

So on most compilers, using the "" first checks your local directory, and if it doesn't find a match then moves on to check the system paths. Using <> starts the search with system headers.

Same-origin policy

You can't access an <iframe> with different origin using JavaScript, it would be a huge security flaw if you could do it. For the same-origin policy browsers block scripts trying to access a frame with a different origin.

Origin is considered different if at least one of the following parts of the address isn't maintained:

protocol://hostname:port/...

Protocol, hostname and port must be the same of your domain if you want to access a frame.

^{NOTE: Internet Explorer is known to not strictly follow this rule, see here for details.}

Examples

Here's what would happen trying to access the following URLs from http://www.example.com/home/index.html

URL                                             RESULT 
http://www.example.com/home/other.html       -> Success 
http://www.example.com/dir/inner/another.php -> Success 
http://www.example.com:80                    -> Success (default port for HTTP) 
http://www.example.com:2251                  -> Failure: different port 
http://data.example.com/dir/other.html       -> Failure: different hostname 
https://www.example.com/home/index.html:80   -> Failure: different protocol
ftp://www.example.com:21                     -> Failure: different protocol & port 
https://google.com/search?q=james+bond       -> Failure: different protocol, port & hostname 

Workaround

Even though same-origin policy blocks scripts from accessing the content of sites with a different origin, if you own both the pages, you can work around this problem using window.postMessage and its relative message event to send messages between the two pages, like this:

• In your main page:

  const frame = document.getElementById('your-frame-id');
  frame.contentWindow.postMessage(/*any variable or object here*/, 'http://your-second-site.com');
  

  The second argument to postMessage() can be '*' to indicate no preference about the origin of the destination. A target origin should always be provided when possible, to avoid disclosing the data you send to any other site.

• In your <iframe> (contained in the main page):

  window.addEventListener('message', event => {
      // IMPORTANT: check the origin of the data! 
      if (event.origin.startsWith('http://your-first-site.com')) { 
          // The data was sent from your site.
          // Data sent with postMessage is stored in event.data:
          console.log(event.data); 
      } else {
          // The data was NOT sent from your site! 
          // Be careful! Do not use it. This else branch is
          // here just for clarity, you usually shouldn't need it.
          return; 
      } 
  }); 
  

This method can be applied in both directions, creating a listener in the main page too, and receiving responses from the frame. The same logic can also be implemented in pop-ups and basically any new window generated by the main page (e.g. using window.open()) as well, without any difference.

Disabling same-origin policy in your browser

There already are some good answers about this topic (I just found them googling), so, for the browsers where this is possible, I'll link the relative answer. However, please remember that disabling the same-origin policy will only affect your browser. Also, running a browser with same-origin security settings disabled grants any website access to cross-origin resources, so it's very unsafe and should NEVER be done if you do not know exactly what you are doing (e.g. development purposes).

• Google Chrome
• Mozilla Firefox
• Safari
• Opera
• Microsoft Edge: not possible
• Microsoft Internet Explorer

In order to best standardise your @font-face embedded fonts across browsers try including the below inside your @font-face declaration or on your body font styling:

speak: none;
font-style: normal;
font-weight: normal;
font-variant: normal;
text-transform: none;
line-height: 1;
-webkit-font-smoothing: antialiased;

At present there looks to be no universal fix across all platforms and browser builds. As stated frequently all browsers/OS have different text rendering engines.

Use this method:

app.run(debug=True)

It will auto-reload the flask app when a code change happens.

Sample code:

from flask import Flask

app = Flask(__name__)

@app.route("/")
def index():
   return "Hello World"


if __name__ == '__main__':
  app.run(debug=True)

Well, if you want save time not reloading the webpage everytime when changes happen, then you can try the keyboard shortcut Ctrl + R to reload the page quickly.

-> cd ..

-> cd project_dir

-> php artisan ('works fine')

in my case, i removed the directory and again clone the repo from the same directory through terminal. then i went one step back and step into my project folder again and the problem was gone.

Just copy the script tag for adding the bootstrap.js from the head section to the end of the body. Then everything should work fine even without the scripts to activate the tabs.

Why not use a mechanism similar to Apache cron jobs? http://en.wikipedia.org/wiki/Cron

For calendar\scheduling I'd use slightly different values for "bits" to accommodate standard calendar reoccurence events - instead of [day of week (0 - 7), month (1 - 12), day of month (1 - 31), hour (0 - 23), min (0 - 59)]

-- I'd use something like [Year (repeat every N years), month (1 - 12), day of month (1 - 31), week of month (1-5), day of week (0 - 7)]

Hope this helps.

You can definitely do this with vanilla JS like stecb has shown, but I think each is the best answer to the core question concerning how to do it with lodash.

_.each( myObject.options, ( val, key ) => { 
    console.log( key, val ); 
} );

Like JohnnyHK mentioned, there is also the has method which would be helpful for the use case, but from what is originally stated set may be more useful. Let's say you wanted to add something to this object dynamically as you've mentioned:

let dynamicKey = 'someCrazyProperty';
let dynamicValue = 'someCrazyValue';

_.set( myObject.options, dynamicKey, dynamicValue );

That's how I'd do it, based on the original description.

Breaking news: I've added another answer that uses an Observable rather than an EventEmitter. I recommend that answer over this one. And actually, using an EventEmitter in a service is bad practice.

Original answer: (don't do this)

Put the EventEmitter into a service, which allows the ObservingComponent to directly subscribe (and unsubscribe) to the event:

import {EventEmitter} from 'angular2/core';

export class NavService {
  navchange: EventEmitter<number> = new EventEmitter();
  constructor() {}
  emit(number) {
    this.navchange.emit(number);
  }
  subscribe(component, callback) {
    // set 'this' to component when callback is called
    return this.navchange.subscribe(data => call.callback(component, data));
  }
}

@Component({
  selector: 'obs-comp',
  template: 'obs component, index: {{index}}'
})
export class ObservingComponent {
  item: number;
  subscription: any;
  constructor(private navService:NavService) {
   this.subscription = this.navService.subscribe(this, this.selectedNavItem);
  }
  selectedNavItem(item: number) {
    console.log('item index changed!', item);
    this.item = item;
  }
  ngOnDestroy() {
    this.subscription.unsubscribe();
  }
}

@Component({
  selector: 'my-nav',
  template:`
    <div class="nav-item" (click)="selectedNavItem(1)">item 1 (click me)</div>
  `,
})
export class Navigation {
  constructor(private navService:NavService) {}
  selectedNavItem(item: number) {
    console.log('selected nav item ' + item);
    this.navService.emit(item);
  }
}

If you try the Plunker, there are a few things I don't like about this approach:

• ObservingComponent needs to unsubscribe when it is destroyed
• we have to pass the component to subscribe() so that the proper this is set when the callback is called

Update: An alternative that solves the 2nd bullet is to have the ObservingComponent directly subscribe to the navchange EventEmitter property:

constructor(private navService:NavService) {
   this.subscription = this.navService.navchange.subscribe(data =>
     this.selectedNavItem(data));
}

If we subscribe directly, then we wouldn't need the subscribe() method on the NavService.

To make the NavService slightly more encapsulated, you could add a getNavChangeEmitter() method and use that:

getNavChangeEmitter() { return this.navchange; }  // in NavService

constructor(private navService:NavService) {  // in ObservingComponent
   this.subscription = this.navService.getNavChangeEmitter().subscribe(data =>
     this.selectedNavItem(data));
}

Type Conversions T() where T is the desired datatype of the result are quite simple in GoLang.

In my program, I scan an integer i from the user input, perform a type conversion on it and store it in the variable f. The output prints the float64 equivalent of the int input. float32 datatype is also available in GoLang

Code:

package main
import "fmt"
func main() {
    var i int
    fmt.Println("Enter an Integer input: ")
    fmt.Scanf("%d", &i)
    f := float64(i)
    fmt.Printf("The float64 representation of %d is %f\n", i, f)
}

Solution:

>>> Enter an Integer input:
>>> 232332
>>> The float64 representation of 232332 is 232332.000000

First of all you have to understand the nature of

response.sendRedirect(newUrl);

It is giving the client (browser) 302 http code response with an URL. The browser then makes a separate GET request on that URL. And that request has no knowledge of headers in the first one.

So sendRedirect won't work if you need to pass a header from Servlet A to Servlet B.

If you want this code to work - use RequestDispatcher in Servlet A (instead of sendRedirect). Also, it is always better to use relative path.

public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException
{
    String userName=request.getParameter("userName");
    String newUrl = "ServletB";
    response.addHeader("REMOTE_USER", userName);
    RequestDispatcher view = request.getRequestDispatcher(newUrl);
    view.forward(request, response);
}

========================

public void doPost(HttpServletRequest request, HttpServletResponse response)
{
    String sss = response.getHeader("REMOTE_USER");
}

So this is probably waaaaaay late to the party but the actual problem is an error or rather the repetition of the same error in three batch files.

C:\Program Files(x86)\Microsoft Visual Studio 10.0\Common7\Tools\VCVarsQueryRegistry.bat

C:\Program Files(x86)\Microsoft Visual Studio 10.0\Common7\Tools\vsvars32.bat

C:\Program Files(x86)\Microsoft Visual Studio 10.0\VC\bin\vcvars32.bat

The pattern of the error is everywhere a for loop is used to loop through registry values. It looks like this:

@for /F "tokens=1,2*" %%i in ('reg query "%1\SOFTWARE\Microsoft\VisualStudio\SxS\VS7" /v "10.0"') DO (
    @if "%%i"=="10.0" (
        @SET "VS100COMNTOOLS=%%k"
    )
)

The problem is the second occurrence of %%i. The way the loop construct works is the first %% variable is the first token, the next is the second and so on. So the second %%i should be a %%j (or whatever you want) so that it points to the value that would possibly be a "10.0". You can tell the developer wanted to use i,j,k as the values because in the enclosed @SET in the if, they use %%k. Which would be the path.

So, in short, go through all these types of loops in the three files above and change the second occurrence of %%i to %%k and everything will work like it's supposed to. So it should look like this:

@for /F "tokens=1,2*" %%i in ('reg query "%1\SOFTWARE\Microsoft\VisualStudio\SxS\VS7" /v "10.0"') DO (
    @if "%%j"=="10.0" (
        @SET "VS100COMNTOOLS=%%k"
    )
)

Hope this helps. Not sure if this applies to all versions. I only know that it does apply to VS 2010 (SP1).

Which specific index? If you want 'Add New' to be first on the dropdownlist you can add it though the code like this:

<asp:DropDownList ID="DropDownList1" AppendDataBoundItems="true" runat="server">
     <asp:ListItem Text="Add New" Value="0" />
</asp:DropDownList>

If you want to add it at a different index, maybe the last then try:

ListItem lst = new ListItem ( "Add New" , "0" );

DropDownList1.Items.Insert( DropDownList1.Items.Count-1 ,lst);

Add double quotes to use caret operator in version number.

composer require middlewares/whoops "^0.4"

I haven't reproduced the issue, but perhaps this method would solve it: (writing line by line to stdout rather than using print)

import sys
with open('a.txt', 'r') as f1:
    for line in f1:
        sys.stdout.write(line)

You could catch the broken pipe? This writes the file to stdout line by line until the pipe is closed.

import sys, errno
try:
    with open('a.txt', 'r') as f1:
        for line in f1:
            sys.stdout.write(line)
except IOError as e:
    if e.errno == errno.EPIPE:
        # Handle error

You also need to make sure that othercommand is reading from the pipe before it gets too big - https://unix.stackexchange.com/questions/11946/how-big-is-the-pipe-buffer

Here are detailed instructions combining getting rid of all MySQL from your Mac then installing it The Brew Way as Sedorner wrote above:

Remove MySQL completely per The Tech Lab

• ps -ax | grep mysql
• stop and kill any MySQL processes
• sudo rm /usr/local/mysql
• sudo rm -rf /usr/local/var/mysql
• sudo rm -rf /usr/local/mysql*
• sudo rm ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist
• sudo rm -rf /Library/StartupItems/MySQLCOM
• sudo rm -rf /Library/PreferencePanes/My*
• launchctl unload -w ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist
• edit /etc/hostconfig and remove the line MYSQLCOM=-YES-
• rm -rf ~/Library/PreferencePanes/My*
• sudo rm -rf /Library/Receipts/mysql*
• sudo rm -rf /Library/Receipts/MySQL*
• sudo rm -rf /private/var/db/receipts/*mysql*
• sudo rm -rf /tmp/mysql*
• try to run mysql, it shouldn't work

Brew install MySQL per user Sedorner from this StackOverflow answer

• brew doctor and fix any errors

• brew remove mysql

• brew cleanup

• brew update

• brew install mysql

• unset TMPDIR

    mysql_install_db --verbose --user=`whoami` --basedir="$(brew --prefix mysql)" --datadir=/usr/local/var/mysql --tmpdir=/tmp # whoami is executed inline
  

• mysql.server start

• run the commands Brew suggests, add MySQL to launchctl so it automatically launches at startup

mysql should now work and be running all the time as expected

Godspeed.

Can you open the 3rd party XML source in Firefox and see what it auto-detects as encoding? Maybe they are using plain old ISO-8859-1, UTF-16 or something else.

If they declare it to be UTF-8, though, and serve something else, their feed is clearly broken. Working around such a broken feed feels horrible to me (even though sometimes unavoidable, I know).

If it's a simple case like "UTF-8 versus ISO-8859-1", you can also try your luck with mb_detect_encoding().

If the trick using position:absolute, position:relative and top/left/bottom/right: 0px is not appropriate for your situation, you could try:

#nav {
    height: inherit;
}

This worked on one of our pages, although I am not sure exactly what other conditions were needed for it to succeed!

See the defaultValue property of a text input, it's also used when you reset the form by clicking an <input type="reset"/> button (http://www.w3schools.com/jsref/prop_text_defaultvalue.asp )

btw, defaultValue and placeholder text are different concepts, you need to see which one better fits your needs

Another possible issue which causes the same behavior is the default parameters in the routing. In my case the controller was located and instantiated correctly, but the POST was blocked because of default Get action specified:

config.Routes.MapHttpRoute(
    name: "GetAllRoute",
    routeTemplate: "api/{controller}.{ext}"/*,
    defaults: new { action = "Get" }*/ // this was causing the issue
);

Another option in case you don't wanna use a plugin:

Ctrl+` or

View -> Show Console

type on the console the following command:

view.encoding()

In case you want to something more intrusive, there's a option to create an shortcut that executes the following command:

sublime.message_dialog(view.encoding())

Below is the Update query which includes JOIN & WHERE both. Same way we can use multiple join/where clause, Hope it will help you :-

UPDATE opportunities_cstm oc JOIN opportunities o ON oc.id_c = o.id
 SET oc.forecast_stage_c = 'APX'
 WHERE o.deleted = 0
   AND o.sales_stage IN('ABC','PQR','XYZ')

I created a Package called HTMLBeautify that does a decent job of reformatting HTML. I based it off of a Perl script I found back in 1997—I updated it to work with all the new fangled modern tags. :)

Check it out and let me know what you think!

https://github.com/rareyman/HTMLBeautify

 //To send from the activity that is calling another activity via myIntent

    myIntent.putExtra("id","10");
    startActivity(myIntent);

    //To receive from another Activity

            Bundle bundle = getIntent().getExtras();
            String id=bundle.getString("id");

I hope your problem is with path & php binary as well. If you have fixed the path as per older answers, please use php-cli instead of php command while running cron job.

It may be possible php_sapi_name() is not returning cli. Its returning something else like cgi-fcgi etc.

/usr/bin/php-cli -q /home/username/public_html/cron/cron.php >/dev/null

I hope it will help.

For simple stuff I just use the following:

unsigned TokenizeString(const std::string& i_source,
                        const std::string& i_seperators,
                        bool i_discard_empty_tokens,
                        std::vector<std::string>& o_tokens)
{
    unsigned prev_pos = 0;
    unsigned pos = 0;
    unsigned number_of_tokens = 0;
    o_tokens.clear();
    pos = i_source.find_first_of(i_seperators, pos);
    while (pos != std::string::npos)
    {
        std::string token = i_source.substr(prev_pos, pos - prev_pos);
        if (!i_discard_empty_tokens || token != "")
        {
            o_tokens.push_back(i_source.substr(prev_pos, pos - prev_pos));
            number_of_tokens++;
        }

        pos++;
        prev_pos = pos;
        pos = i_source.find_first_of(i_seperators, pos);
    }

    if (prev_pos < i_source.length())
    {
        o_tokens.push_back(i_source.substr(prev_pos));
        number_of_tokens++;
    }

    return number_of_tokens;
}

Cowardly disclaimer: I write real-time data processing software where the data comes in through binary files, sockets, or some API call (I/O cards, camera's). I never use this function for something more complicated or time-critical than reading external configuration files on startup.

In the interpreter its easy to restart it and fix such problems. If you don't want to restart the interpreter, there is another way to fix it:

Python 2.6.6 (r266:84292, Dec 27 2010, 00:02:40)
[GCC 4.4.5] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> l = [1,2,3]

  File "<stdin>", line 1, in <module>
TypeError: 'int' object is not callable
>>> import sys
>>> sum = sys.modules['__builtin__'].sum # -- fixing sum

This also comes in handy if you happened to assign a value to any other builtin, like dict or list

I was using Postman to test my Laravel API.

I received an error that stated

"SQLSTATE[42S22]: Column not found: 1054 Unknown column" because Laravel was trying to automatically create two columns "created_at" and "updated_at".

I had to enter public $timestamps = false; to my model. Then, I tested again with Postman and saw that an "id" = 0 variable was being created in my database.

I finally had to add public $incrementing false; to fix my API.

This is a working solution based on @Chris answer above, but fixed so that upon subsequence clicks of the trigger element, you don't have to click the element twice.

Using .popover('hide) manually messes up bootstraps internal state, as noted in the comments.

var closePopover = function(eventShown) {
   // Set the reference to the calling element
   var $caller = $('#' + this.id);

   // Set the reference to the popover
   var $popover = $('#' + $(eventShown.target).attr('aria-describedby'));

       // Unbind any pre-existing event handlers to prevent duplicate clicks
       $popover.find('.popover-close').off('click');

       // Bind event handler to close button
       $popover.find('.popover-close').on('click', function(e) {

          // Trigger a click on the calling element, to maintain bootstrap's internal state
          $caller.trigger('click');
        });
 }

$('.popoverTriggerElement').popover({
   trigger: 'click'
})
.on('shown.bs.popover', closePopover)

Now, you can use the close button without duplicating the click events, and keeping bootstraps internal state in check so it works as expected.

Try adding System.Web as a reference to your project.

Yet another approach is using window.scrollBy

I think this is what you want:

/grand/parent/child[@id="#grand"]

Yow can use querySelectorAll to select all the classes and loop through them to assign the eventListener. The if condition checks if it contains the class name.

const arrClass = document.querySelectorAll(".className");
for (let i of arrClass) {
  i.addEventListener("click", (e) => {
    if (e.target.classList.contains("className")) {
        console.log("Perfrom Action")
    }
  })
}

Around 1:51 in the video, notice how she puts a <script> tag in there? The way it works is like this:

Create an html file (that's just a text file with a .html ending) somewhere on your computer. In the same folder that you put index.html, put a javascript file (that's just a textfile with a .js ending - let's call it game.js). Then, in your index.html file, put some html that includes the script tag with game.js, like Mary did in the video. index.html should look something like this:

<html>
    <head>
        <script src="game.js"></script>
    </head>
</html>

Now, double click on that file in finder, and it should open it up in your browser. To open up the console to see the output of your javascript code, hit Command-alt-j (those three buttons at the same time).

Good luck on your journey, hope it's as fun for you as it has been for me so far :)

I wrote something like this the other day:

import time, datetime
def nowString():
    # we want something like '2007-10-18 14:00+0100'
    mytz="%+4.4d" % (time.timezone / -(60*60) * 100) # time.timezone counts westwards!
    dt  = datetime.datetime.now()
    dts = dt.strftime('%Y-%m-%d %H:%M')  # %Z (timezone) would be empty
    nowstring="%s%s" % (dts,mytz)
    return nowstring

So the interesting part for you is probably the line starting with "mytz=...". time.timezone returns the local timezone, albeit with opposite sign compared to UTC. So it says "-3600" to express UTC+1.

Despite its ignorance towards Daylight Saving Time (DST, see comment), I'm leaving this in for people fiddling around with time.timezone.

I know this is old, but I would like to suggest using a linear-gradient to achieve the same effect instead of margin offset. This is will maintain any content at its original place.

With EF or LINQ to SQL:

var item = db.Items.OrderByDescending(i => i.Value).FirstOrDefault();

With LINQ to Objects I suggest to use morelinq extension MaxBy (get morelinq from nuget):

var item = items.MaxBy(i => i.Value);

Best thing I came up without Java 8 was:

public static <T> T[] toArray(List<T> list, Class<T> objectClass) {
    if (list == null) {
        return null;
    }

    T[] listAsArray = (T[]) Array.newInstance(objectClass, list.size());
    list.toArray(listAsArray);
    return listAsArray;
}

If anyone has a better way to do this, please share :)

You just need to divide each element by the sum of the values in its column.

Doing this should suffice:

data.perc <- apply(data, 2, function(x){x/sum(x)})

Note that the second parameter tells apply to apply the provided function to columns (using 1 you would apply it to rows). The anonymous function, then, gets passed each data column, one at a time.

One other way...

CONVERT(varchar, DATEPART(yyyy, @datetime)) + '/' + CONVERT(varchar, DATEPART(mm, @datetime)) + '/' + CONVERT(varchar, DATEPART(dd, @datetime)) 

If some of your services are balking into ulimits, it's sometimes easier to put appropriate commands into service's init-script. For example, when Apache is reporting

[alert] (11)Resource temporarily unavailable: apr_thread_create: unable to create worker thread

Try to put ulimit -s unlimited into /etc/init.d/httpd. This does not require a server reboot.

May use this-

#if defined CONDITION1 || defined CONDITION2
//your code here
#endif

This also does the same-

#if defined(CONDITION1) || defined(CONDITION2)
//your code here
#endif

Further-

• AND: #if defined CONDITION1 && defined CONDITION2
• XOR: #if defined CONDITION1 ^ defined CONDITION2
• AND NOT: #if defined CONDITION1 && !defined CONDITION2

Getting SOAP working usually does not require compiling PHP from source. I would recommend trying that only as a last option.

For good measure, check to see what your phpinfo says, if anything, about SOAP extensions:

$ php -i | grep -i soap

to ensure that it is the PHP extension that is missing.

Assuming you do not see anything about SOAP in the phpinfo, see what PHP SOAP packages might be available to you.

In Ubuntu/Debian you can search with:

$ apt-cache search php | grep -i soap

or in RHEL/Fedora you can search with:

$ yum search php | grep -i soap

There are usually two PHP SOAP packages available to you, usually php-soap and php-nusoap. php-soap is typically what you get with configuring PHP with --enable-soap.

In Ubuntu/Debian you can install with:

$ sudo apt-get install php-soap

Or in RHEL/Fedora you can install with:

$ sudo yum install php-soap

After the installation, you might need to place an ini file and restart Apache.

const double pi = boost::math::constants::pi<double>();

cv::Mat distance2ellipse(cv::Mat image, cv::RotatedRect ellipse){
    float distance = 2.0f;
    float angle = ellipse.angle;
    cv::Point ellipse_center = ellipse.center;
    float major_axis = ellipse.size.width/2;
    float minor_axis = ellipse.size.height/2;
    cv::Point pixel;
    float a,b,c,d;

    for(int x = 0; x < image.cols; x++)
    {
        for(int y = 0; y < image.rows; y++) 
        {
        auto u =  cos(angle*pi/180)*(x-ellipse_center.x) + sin(angle*pi/180)*(y-ellipse_center.y);
        auto v = -sin(angle*pi/180)*(x-ellipse_center.x) + cos(angle*pi/180)*(y-ellipse_center.y);

        distance = (u/major_axis)*(u/major_axis) + (v/minor_axis)*(v/minor_axis);  

        if(distance<=1)
        {
            image.at<cv::Vec3b>(y,x)[1] = 255;

  return image;

Sometimes using   instead of spaces will work. Clearly it has drawbacks, though.

The pack() method is defined in Window class in Java and it sizes the frame so that all its contents are at or above their preferred sizes.

A quick workaround that worked for me: try using the local ip address (127.0.0.1) instead of 'localhost' in mysql_connect(). This "forces" php to connect through TCP/IP instead of a unix socket.

I'm not sure if this is going to help, but even i faced the exact same problem very recently with oozie-4.2.0 version. After reading through the above answers i have just added the maven option through command line and it worked for me. So, just sharing here.

I'm using java 1.8.0_77, haven't tried with java 1.7

You can send the file and data over in one request using the multipart/form-data content type:

In many applications, it is possible for a user to be presented with a form. The user will fill out the form, including information that is typed, generated by user input, or included from files that the user has selected. When the form is filled out, the data from the form is sent from the user to the receiving application.

The definition of MultiPart/Form-Data is derived from one of those applications...

From http://www.faqs.org/rfcs/rfc2388.html:

"multipart/form-data" contains a series of parts. Each part is expected to contain a content-disposition header [RFC 2183] where the disposition type is "form-data", and where the disposition contains an (additional) parameter of "name", where the value of that parameter is the original field name in the form. For example, a part might contain a header:

Content-Disposition: form-data; name="user"

with the value corresponding to the entry of the "user" field.

You can include file information or field information within each section between boundaries. I've successfully implemented a RESTful service that required the user to submit both data and a form, and multipart/form-data worked perfectly. The service was built using Java/Spring, and the client was using C#, so unfortunately I don't have any Grails examples to give you concerning how to set up the service. You don't need to use JSON in this case since each "form-data" section provides you a place to specify the name of the parameter and its value.

The good thing about using multipart/form-data is that you're using HTTP-defined headers, so you're sticking with the REST philosophy of using existing HTTP tools to create your service.

There are two ways to do that (Python 2.6+):

static method

class Klass(object):
    @staticmethod
    def static_method():
        print "Hello World"

Klass.static_method()

module

your module file, called klass.py

def static_method():
    print "Hello World"

your code:

import klass

klass.static_method()

HTML

<div id="replaceMe">i need to be replaced</div>
<div id="iamReplacement">i am replacement</div>

JavaScript

jQuery('#replaceMe').replaceWith(jQuery('#iamReplacement'));

just use a label tag, that way you can hide the input, and make it work through its related label https://developer.mozilla.org/fr/docs/Web/HTML/Element/Label

Many neural network training algorithms involve making multiple presentations of the entire data set to the neural network. Often, a single presentation of the entire data set is referred to as an "epoch". In contrast, some algorithms present data to the neural network a single case at a time.

"Iteration" is a much more general term, but since you asked about it together with "epoch", I assume that your source is referring to the presentation of a single case to a neural network.

Or a comparison on the class name e.g.

except ClientError as e:
    if 'EntityAlreadyExistsException' == e.__class__.__name__:
        # handle specific error

Because they are dynamically created you can never import the class and catch it using real Python.

Extending @Tinker's answer,

In my case, I needed to make a command | command | command inside the -exec to print both the filename and the found text in files containing a certain text.

I was able to do it with:

find . -name config -type f \( -exec  grep "bitbucket" {} \; -a -exec echo {} \;  \) 

the result is:

    url = [email protected]:a/a.git
./a/.git/config
    url = [email protected]:b/b.git
./b/.git/config
    url = [email protected]:c/c.git
./c/.git/config

A single & (not double &&) is enough or as the top answer suggests you can use 'and'. I also found this in pandas

cities['Is wide and has saint name'] = (cities['Population'] > 1000000) 
& cities['City name'].apply(lambda name: name.startswith('San'))

if we replace the "&" with "and", it won't work.

If your server is not loaded with heavy configuration, the best solution would be to delete the tomcat and set it again.
It will be much easier then doing try and error for 7-10 times!

I recently run into this question in my work place so I think I should say something more here. I will use image to explain how the FTP works as an additional source for previous answer.

Active mode:

Passive mode:

In an active mode configuration, the server will attempt to connect to a random client-side port. So chances are, that port wouldn't be one of those predefined ports. As a result, an attempt to connect to it will be blocked by the firewall and no connection will be established.

A passive configuration will not have this problem since the client will be the one initiating the connection. Of course, it's possible for the server side to have a firewall too. However, since the server is expected to receive a greater number of connection requests compared to a client, then it would be but logical for the server admin to adapt to the situation and open up a selection of ports to satisfy passive mode configurations.

So it would be best for you to configure server to support passive mode FTP. However, passive mode would make your system vulnerable to attacks because clients are supposed to connect to random server ports. Thus, to support this mode, not only should your server have to have multiple ports available, your firewall should also allow connections to all those ports to pass through!

To mitigate the risks, a good solution would be to specify a range of ports on your server and then to allow only that range of ports on your firewall.

For more information, please read the official document.

Thanks @Nicholas Anderson simple and straight , here is your code applied and working at my code using jquery.

HTML .

<input class="rangelog btn border-aero" id="file_fr" name="file_fr[]" multiple type="file" placeholder="{$labels_helpfiles_placeholder_file}">
<span style="cursor: pointer; cursor: hand;" onclick="cleanInputs($('#file_fr'))"><i class="fa fa-trash"></i> Empty chosen files</span>

JS CODE

   function cleanInputs(fileEle){
    $(fileEle).val("");
    var parEle = $(fileEle).parent();
    var newEle = $(fileEle).clone()
    $(fileEle).remove();
    $(parEle).prepend(newEle);
}

Sort values without multiple for-loops (to sort by the keys change index in the sort callback to "0")

const list = {_x000D_
    "you": 100, _x000D_
    "me": 75, _x000D_
    "foo": 116, _x000D_
    "bar": 15_x000D_
  };_x000D_
_x000D_
let sorted = Object.fromEntries(_x000D_
                Object.entries(list).sort( (a,b) => a[1] - b[1] )    _x000D_
             ) _x000D_
console.log('Sorted object: ', sorted) 

This works perfectly for me in Bootstrap 4.

<div class="form-row align-items-center">
   <div class="col-md-2">
     <label for="FirstName" style="margin-bottom:0rem !important;">First Name</label>
 </div>
 <div class="col-md-10">
    <input type="text" id="FirstName" name="FirstName" class="form-control" val=""/>
  /div>
</div>

Use HH for 24 hour hours format:

DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss")

Or the tt format specifier for the AM/PM part:

DateTime.Now.ToString("yyyy-MM-dd hh:mm:ss tt")

Take a look at the custom Date and Time format strings documentation.

You're nearly there, just take out the EXECUTE:

DECLARE
  procId NUMBER;

BEGIN
  PKG1.INIT(1143824, 0, procId);
  DBMS_OUTPUT.PUT_LINE(procId);
END;

One liner using String.protype.matchAll (ES2020):

[...sourceStr.matchAll(new RegExp(searchStr, 'gi'))].map(a => a.index)

Using your values:

const sourceStr = 'I learned to play the Ukulele in Lebanon.';
const searchStr = 'le';
const indexes = [...sourceStr.matchAll(new RegExp(searchStr, 'gi'))].map(a => a.index);
console.log(indexes); // [2, 25, 27, 33]

If you're worried about doing a spread and a map() in one line, I ran it with a for...of loop for a million iterations (using your strings). The one liner averages 1420ms while the for...of averages 1150ms on my machine. That's not an insignificant difference, but the one liner will work fine if you're only doing a handful of matches.

See matchAll on caniuse

Your convention seems to be reasonable. If I were searching for your framework in the Maven repo, I would look for awesome-inhouse-framework-x.y.jar in com.mycompany.awesomeinhouseframework group directory. And I would find it there according to your convention.

Two simple rules work for me:

• reverse-domain-packages for groupId (since such are quite unique) with all the constrains regarding Java packages names
• project name as artifactId (keeping in mind that it should be jar-name friendly i.e. not contain characters that maybe invalid for a file name or just look weird)

Bootstrap-theme.css is the additional CSS file, which is optional for you to use. It gives 3D effects on the buttons and some other elements.

Try this

#include <stdio.h>

struct context;

struct funcptrs{
  void (*func0)(struct context *ctx);
  void (*func1)(void);
};

struct context{
    struct funcptrs fps;
}; 

void func1 (void) { printf( "1\n" ); }
void func0 (struct context *ctx) { printf( "0\n" ); }

void getContext(struct context *con){
    con->fps.func0 = func0;  
    con->fps.func1 = func1;  
}

int main(int argc, char *argv[]){
 struct context c;
   c.fps.func0 = func0;
   c.fps.func1 = func1;
   getContext(&c);
   c.fps.func0(&c);
   getchar();
   return 0;
}

I think you actually provided a good start for the correct answer right in your question (you just need the correct syntax). I had this exact same problem, and putting DISTINCT in a sub-query was indeed less costly than what other answers here have proposed.

select a.FirstName, a.LastName, v.District
from AddTbl a 
inner join (select distinct LastName, District 
    from ValTbl) v
   on a.LastName = v.LastName
order by Firstname   

GhostDoc!

Right-click on the function, select "Document this" and

private bool FindTheFoo(int numberOfFoos)

becomes

/// <summary>
/// Finds the foo.
/// </summary>
/// <param name="numberOfFoos">The number of foos.</param>
/// <returns></returns>
private bool FindTheFoo(int numberOfFoos)

(yes, it is all autogenerated).

It has support for C#, VB.NET and C/C++. It is per default mapped to Ctrl+Shift+D.

Remember: you should add information beyond the method signature to the documentation. Don't just stop with the autogenerated documentation. The value of a tool like this is that it automatically generates the documentation that can be extracted from the method signature, so any information you add should be new information.

That being said, I personally prefer when methods are totally selfdocumenting, but sometimes you will have coding-standards that mandate outside documentation, and then a tool like this will save you a lot of braindead typing.

It means XML namespace.

Basically, every element (or attribute) in XML belongs to a namespace, a way of "qualifying" the name of the element.

Imagine you and I both invent our own XML. You invent XML to describe people, I invent mine to describe cities. Both of us include an element called name. Yours refers to the person’s name, and mine to the city name—OK, it’s a little bit contrived.

<person>
    <name>Rob</name>
    <age>37</age>
    <homecity>
        <name>London</name>
        <lat>123.000</lat>
        <long>0.00</long>
    </homecity>
</person>

If our two XMLs were combined into a single document, how would we tell the two names apart? As you can see above, there are two name elements, but they both have different meanings.

The answer is that you and I would both assign a namespace to our XML, which we would make unique:

<personxml:person xmlns:personxml="http://www.your.example.com/xml/person"
                  xmlns:cityxml="http://www.my.example.com/xml/cities">
    <personxml:name>Rob</personxml:name>
    <personxml:age>37</personxml:age>
    <cityxml:homecity>
        <cityxml:name>London</cityxml:name>
        <cityxml:lat>123.000</cityxml:lat>
        <cityxml:long>0.00</cityxml:long>
    </cityxml:homecity>
</personxml:person>

Now we’ve fully qualified our XML, there is no ambiguity as to what each name element means. All of the tags that start with personxml: are tags belonging to your XML, all the ones that start with cityxml: are mine.

There are a few points to note:

• If you exclude any namespace declarations, things are considered to be in the default namespace.

• If you declare a namespace without the identifier, that is, xmlns="http://somenamespace", rather than xmlns:rob="somenamespace", it specifies the default namespace for the document.

• The actual namespace itself, often a IRI, is of no real consequence. It should be unique, so people tend to choose a IRI/URI that they own, but it has no greater meaning than that. Sometimes people will place the schema (definition) for the XML at the specified IRI, but that is a convention of some people only.

• The prefix is of no consequence either. The only thing that matters is what namespace the prefix is defined as. Several tags beginning with different prefixes, all of which map to the same namespace are considered to be the same.

  For instance, if the prefixes personxml and mycityxml both mapped to the same namespace (as in the snippet below), then it wouldn't matter if you prefixed a given element with personxml or mycityxml, they'd both be treated as the same thing by an XML parser. The point is that an XML parser doesn't care what you've chosen as the prefix, only the namespace it maps too. The prefix is just an indirection pointing to the namespace.

  <personxml:person 
       xmlns:personxml="http://example.com/same/url"
       xmlns:mycityxml="http://example.com/same/url" />
  

• Attributes can be qualified but are generally not. They also do not inherit their namespace from the element they are on, as opposed to elements (see below).

Also, element namespaces are inherited from the parent element. In other words I could equally have written the above XML as

<person xmlns="http://www.your.example.com/xml/person">
    <name>Rob</name>
    <age>37</age>
    <homecity xmlns="http://www.my.example.com/xml/cities">
        <name>London</name>
        <lat>123.000</lat>
        <long>0.00</long>
    </homecity>
</person>

It's a lot easier than that:

List = open("filename.txt").readlines()

This returns a list of each line in the file.

Tried all of the options above. What worked for me was:

1. Make sure the request to server have withCredentials set to true. XMLHttpRequest from a different domain cannot set cookie values for their own domain unless withCredentials is set to true before making the request.
2. Do not set Domain
3. Set Path=/

Resulting Set-Cookie header:

Set-Cookie: session_token=74528588-7c48-4546-a3ae-4326e22449e5; Expires=Sun, 16 Aug 2020 04:40:42 GMT; Path=/

If this is for debug output then OutputDebugString is what you want. A useful macro :

#define DBOUT( s )            \
{                             \
   std::ostringstream os_;    \
   os_ << s;                   \
   OutputDebugString( os_.str().c_str() );  \
}

This allows you to say things like:

DBOUT( "The value of x is " << x );

You can extend this using the __LINE__ and __FILE__ macros to give even more information.

For those in Windows and wide character land:

#include <Windows.h>
#include <iostream>
#include <sstream>

 #define DBOUT( s )            \
{                             \
   std::wostringstream os_;    \
   os_ << s;                   \
   OutputDebugStringW( os_.str().c_str() );  \
}

So the way I would solve this problem is to make sure the two datetimes are in the right timezone.

I can see that you are using datetime.now() which will return the systems current time, with no tzinfo set.

tzinfo is the information attached to a datetime to let it know what timezone it is in. If you are using naive datetime you need to be consistent through out your system. I would highly recommend only using datetime.utcnow()

seeing as somewhere your are creating datetime that have tzinfo associated with them, what you need to do is make sure those are localized (has tzinfo associated) to the correct timezone.

Take a look at Delorean, it makes dealing with this sort of thing much easier.

I'm passing to Django's template a function, which returns me some records

Why don't you pass to Django template the variable storing function's return value, instead of the function?

I've tried to set fuction's return value to a variable and iterate over variable, but there seems to be no way to set variable in Django template.

You should set variables in Django views instead of templates, and then pass them to the template.

Just for reference i had this problem mixing both multi_query and query in the same code:

$connection->multi_query($query);
...
$connection->query($otherQuery);

Which for what i read had unconsumed results pending, therefore causing in the mentioned error.

I solved it with a loop consuming all the results of the multi_query:

$connection->multi_query($query);
while ($connection->next_result()); // <--- solves the problem
...
$connection->query($otherQuery);

In my case all the queries in the multi_query where inserts so i had no interest in the results themselves.

after onclick of any action do below step

((EditText) findViewById(R.id.yoursXmlId)).setText("");

or

write this in XML file

<EditText
---------- other stuffs ------ 
android:hint="Enter Name" /> 

its works fine for me. Hope to you all.

Tomcat is not running. Your search is showing you the grep process, which is searching for tomcat. Of course, by the time you see that output, grep is no longer running, so the pid is no longer valid.

upstream in the github example is just the name they've chosen to refer to that repository. You may choose any that you like when using git remote add. Depending on what you select for this name, your git pull usage will change. For example, if you use:

git remote add upstream git://github.com/somename/original-project.git

then you would use this to pull changes:

git pull upstream master

But, if you choose origin for the name of the remote repo, your commands would be:

To name the remote repo in your local config: git remote add origin git://github.com/somename/original-project.git

And to pull: git pull origin master

PATH mode is used in generating XML from a SELECT query

1. SELECT   
       ID,  
       Name  
FROM temp1
FOR XML PATH;  

Ouput:
<row>
<ID>1</ID>
<Name>aaa</Name>
</row>

<row>
<ID>1</ID>
<Name>bbb</Name>
</row>

<row>
<ID>1</ID>
<Name>ccc</Name>
</row>

<row>
<ID>1</ID>
<Name>ddd</Name>
</row>

<row>
<ID>1</ID>
<Name>eee</Name>
</row>

The Output is element-centric XML where each column value in the resulting rowset is wrapped in an row element. Because the SELECT clause does not specify any aliases for the column names, the child element names generated are the same as the corresponding column names in the SELECT clause.

For each row in the rowset a tag is added.

2.
SELECT   
       ID,  
       Name  
FROM temp1
FOR XML PATH('');

Ouput:
<ID>1</ID>
<Name>aaa</Name>
<ID>1</ID>
<Name>bbb</Name>
<ID>1</ID>
<Name>ccc</Name>
<ID>1</ID>
<Name>ddd</Name>
<ID>1</ID>
<Name>eee</Name>

For Step 2: If you specify a zero-length string, the wrapping element is not produced.

3. 

    SELECT   

           Name  
    FROM temp1
    FOR XML PATH('');

    Ouput:
    <Name>aaa</Name>
    <Name>bbb</Name>
    <Name>ccc</Name>
    <Name>ddd</Name>
    <Name>eee</Name>

4. SELECT   
        ',' +Name  
FROM temp1
FOR XML PATH('')

Ouput:
,aaa,bbb,ccc,ddd,eee

In Step 4 we are concatenating the values.

5. SELECT ID,
    abc = (SELECT   
            ',' +Name  
    FROM temp1
    FOR XML PATH('') )
FROM temp1

Ouput:
1   ,aaa,bbb,ccc,ddd,eee
1   ,aaa,bbb,ccc,ddd,eee
1   ,aaa,bbb,ccc,ddd,eee
1   ,aaa,bbb,ccc,ddd,eee
1   ,aaa,bbb,ccc,ddd,eee


6. SELECT ID,
    abc = (SELECT   
            ',' +Name  
    FROM temp1
    FOR XML PATH('') )
FROM temp1 GROUP by iD

Ouput:
ID  abc
1   ,aaa,bbb,ccc,ddd,eee

In Step 6 we are grouping the date by ID.

STUFF( source_string, start, length, add_string ) Parameters or Arguments source_string The source string to modify. start The position in the source_string to delete length characters and then insert add_string. length The number of characters to delete from source_string. add_string The sequence of characters to insert into the source_string at the start position.

SELECT ID,
    abc = 
    STUFF (
        (SELECT   
                ',' +Name  
        FROM temp1
        FOR XML PATH('')), 1, 1, ''
    )
FROM temp1 GROUP by iD

Output:
-----------------------------------
| Id        | Name                |
|---------------------------------|
| 1         | aaa,bbb,ccc,ddd,eee |
-----------------------------------

If you want to pass in the value to use, you have to use the enum type you declared and directly use the supplied value:

public string CreateFile(string id, string name, string description,
              /* --> */  SupportedPermissions supportedPermissions)
{
    file = new File
    {  
        Name = name,
        Id = id,
        Description = description,
        SupportedPermissions = supportedPermissions // <---
    };

    return file.Id;
}

If you instead want to use a fixed value, you don't need any parameter at all. Instead, directly use the enum value. The syntax is similar to a static member of a class:

public string CreateFile(string id, string name, string description) // <---
{
    file = new File
    {  
        Name = name,
        Id = id,
        Description = description,
        SupportedPermissions = SupportedPermissions.basic // <---
    };

    return file.Id;
}

I faced this problem where the following query doesn't work as expected:

select 1 where getdate()<>null

we expect it to show 1 because getdate() doesn't return null. I guess it has something to do with SQL failing to cast null as datetime and skipping the row! of course we know we should use IS or IS NOT keywords to compare a variable with null but when comparing two parameters it gets hard to handle the null situation. as a solution you can create your own compare function like the following:

CREATE FUNCTION [dbo].[fnCompareDates]
(
    @DateTime1 datetime,
    @DateTime2 datetime
)
RETURNS bit
AS
BEGIN
    if (@DateTime1 is null and @DateTime2 is null) return 1;
    if (@DateTime1 = @DateTime2) return 1;
    return 0
END

and re writing the query like:

select 1 where dbo.fnCompareDates(getdate(),null)=0

You need to set both the user-agent and the referer:

 wget  --header="Accept: text/html" --user-agent="Mozilla/5.0 (Macintosh; Intel Mac OS X 10.8; rv:21.0) Gecko/20100101 Firefox/21.0" --referrer  connect.wso2.com http://dist.wso2.org/products/carbon/4.2.0/wso2carbon-4.2.0.zip

I'm surprised nobody pointed out JSON's [] method, which makes it very easy and transparent to decode and encode from/to JSON.

If object is string-like, parse the string and return the parsed result as a Ruby data structure. Otherwise generate a JSON text from the Ruby data structure object and return it.

Consider this:

require 'json'

hash = {"val":"test","val1":"test1","val2":"test2"} # => {:val=>"test", :val1=>"test1", :val2=>"test2"}
str = JSON[hash] # => "{\"val\":\"test\",\"val1\":\"test1\",\"val2\":\"test2\"}"

str now contains the JSON encoded hash.

It's easy to reverse it using:

JSON[str] # => {"val"=>"test", "val1"=>"test1", "val2"=>"test2"}

Custom objects need to_s defined for the class, and inside it convert the object to a Hash then use to_json on it.

You're close.

std::list<Student>::iterator it;
for (it = data.begin(); it != data.end(); ++it){
    std::cout << it->name;
}

Note that you can define it inside the for loop:

for (std::list<Student>::iterator it = data.begin(); it != data.end(); ++it){
    std::cout << it->name;
}

And if you are using C++11 then you can use a range-based for loop instead:

for (auto const& i : data) {
    std::cout << i.name;
}

Here auto automatically deduces the correct type. You could have written Student const& i instead.

I think the Amelia library does a nice job in handling missing data also includes a map for visualizing the missing rows.

install.packages("Amelia")
library(Amelia)
missmap(airquality)

You can also run the following code will return the logic values of na

row.has.na <- apply(training, 1, function(x){any(is.na(x))})

Twitter Bootstrap assigns the active class to the li element that represents the active tab:

$("ul#sampleTabs li.active")

An alternative is to bind the shown event of each tab, and save the active tab:

var activeTab = null;
$('a[data-toggle="tab"]').on('shown', function (e) {
  activeTab = e.target;
})

Unfortunately no with current state of affairs in CSS.

Ellipsis rendering has prerequisite white-space:nowrap that effectively means: ellipsis are drawn on single line text containers only.

I think it'd be okay if you commented it, e.g. // ^ == XOR.

A solid and easy way to handle it in single threaded code would be to catch it and retrow it in a RuntimeException, to avoid the need to declare it for every method.

If you mean to create a new form when a button is clicked, the below code may be of some use to you:

private void settingsButton_Click(Object sender, EventArgs e)
{
    // Create a new instance of the Form2 class
    Form2 settingsForm = new Form2();

    // Show the settings form
    settingsForm.Show();
}

From here, you could also use the 'Show Dialog' method

Using python to calculate this, for example(written in python 3), 50% transparency :

Architecture is the resulting collection of design patterns to build a system.

I guess Design is the creativity used to put all this together?

Html:

<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<meta name="x" content="xx" />

vs Php:

<?php header('Content-type: text/html; charset=ISO-8859-1'); ?>
<!DOCTYPE HTML>
<html>
<head>
<meta name="x" content="xx" />

If you want to ensure a file is closed you should use the block form of File.open:

File.open("myFile.txt", "w") do |file|
  begin
    file << "#{content} \n"
  rescue
  #handle the error here
  end
end

I use ? (0x25B8) for the right arrow, often to show a collapsed list; and I pair it with ? (0x25BE) to show the list opened up. Both are unobtrusive.

The much longer example below combines some of the useful snippets above:

• You can specify any number of sheets you want to copy across
• You can copy entire sheets, i.e. like dragging the tab across, or you can copy over the contents of cells as values-only but preserving formatting.

It could still do with a lot of work to make it better (better error-handling, general cleaning up), but it hopefully provides a good start.

Note that not all formatting is carried across because the new sheet uses its own theme's fonts and colours. I can't work out how to copy those across when pasting as values only.

You say that if int(splitLine[0]) > int(lastUnix): is causing the trouble, but you don't actually show anything which suggests that. I think this line is the problem instead:

print 'Pulled', + stock

Do you see why this line could cause that error message? You want either

>>> stock = "AAAA"
>>> print 'Pulled', stock
Pulled AAAA

or

>>> print 'Pulled ' + stock
Pulled AAAA

not

>>> print 'Pulled', + stock
PulledTraceback (most recent call last):
  File "<ipython-input-5-7c26bb268609>", line 1, in <module>
    print 'Pulled', + stock
TypeError: bad operand type for unary +: 'str'

You're asking Python to apply the + symbol to a string like +23 makes a positive 23, and she's objecting.

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.

First Open The Sublime Text 2.

And top menu bar on select the Preferences.

And than select the Key Bindings -User.

And than put this code,

[
    { "keys": ["ctrl+shift+c"], "command": "toggle_comment", "args": { "block": false } },

    { "keys": ["ctrl+shift+c"], "command": "toggle_comment", "args": { "block": true } }
]

I use Ctrl+Shift+C, You also different short cut key use.

For all those who came here and did indeed use Date typed Variables, here is the solution I found. It does also apply to TypeScript.

I was facing this error because I tried to compare two dates using the following Method

var res = dat1.getTime() > dat2.getTime(); // or any other comparison operator

However Im sure I used a Date object, because Im using angularjs with typescript, and I got the data from a typed API call.

Im not sure why the error is raised, but I assume that because my Object was created by JSON deserialisation, possibly the getTime() method was simply not added to the prototype.

Solution

In this case, recreating a date-Object based on your dates will fix the issue.

var res = new Date(dat1).getTime() > new Date(dat2).getTime()

Edit:

I was right about this. Types will be cast to the according type but they wont be instanciated. Hence there will be a string cast to a date, which will obviously result in a runtime exception.

The trick is, if you use interfaces with non primitive only data such as dates or functions, you will need to perform a mapping after your http request.

class Details {
    description: string;
    date: Date;
    score: number;
    approved: boolean;

    constructor(data: any) {
      Object.assign(this, data);
    }
}

and to perform the mapping:

public getDetails(id: number): Promise<Details> {
    return this.http
               .get<Details>(`${this.baseUrl}/api/details/${id}`)
               .map(response => new Details(response.json()))
               .toPromise();
}

for arrays use:

public getDetails(): Promise<Details[]> {
    return this.http
               .get<Details>(`${this.baseUrl}/api/details`)
               .map(response => {
                   const array = JSON.parse(response.json()) as any[];
                   const details = array.map(data => new Details(data));
                   return details;
               })
               .toPromise();
}

Here's my solution (requires no jQuery... just JavaScript):

function argsToArray(args) {
  var r = []; for (var i = 0; i < args.length; i++)
    r.push(args[i]);
  return r;
}
function bind() {
  var initArgs = argsToArray(arguments);
  var fx =        initArgs.shift();
  var tObj =      initArgs.shift();
  var args =      initArgs;
  return function() {
    return fx.apply(tObj, args.concat(argsToArray(arguments)));
  };
}
var salutation = argsToArray(document.getElementsByClassName('salutation'));
salutation.forEach(function(checkbox) {
  checkbox.addEventListener('change', bind(function(checkbox, salutation) {
    var numChecked = salutation.filter(function(checkbox) { return checkbox.checked; }).length;
    if (numChecked >= 4)
      checkbox.checked = false;
  }, null, checkbox, salutation), false);
});

Put this in a script block at the end of <body> and the snippet will do its magic, limiting the number of checkboxes checked in maximum to three (or whatever number you specify).

Here, I'll even give you a test page (paste it into a file and try it):

<!DOCTYPE html><html><body>

<input type="checkbox" class="salutation">
<input type="checkbox" class="salutation">

<input type="checkbox" class="salutation">
<input type="checkbox" class="salutation">
<input type="checkbox" class="salutation">
<input type="checkbox" class="salutation">
<input type="checkbox" class="salutation">
<script>
    function argsToArray(args) {
      var r = []; for (var i = 0; i < args.length; i++)
        r.push(args[i]);
      return r;
    }
    function bind() {
      var initArgs = argsToArray(arguments);
      var fx =        initArgs.shift();
      var tObj =      initArgs.shift();
      var args =      initArgs;
      return function() {
        return fx.apply(tObj, args.concat(argsToArray(arguments)));
      };
    }
    var salutation = argsToArray(document.getElementsByClassName('salutation'));
    salutation.forEach(function(checkbox) {
      checkbox.addEventListener('change', bind(function(checkbox, salutation) {
        var numChecked = salutation.filter(function(checkbox) { return checkbox.checked; }).length;
        if (numChecked >= 3)
          checkbox.checked = false;
      }, null, checkbox, salutation), false);
    });
</script></body></html>

I have got a same question like you, I use wireshark to capture my sent TCP packets, I found when I use mysql bin to connect the remote host, it connects remote's 3307 port, that's my falut in /etc/mysql/my.cnf, 3307 is another project mysql port, but I change that config in my.cnf [client] part, when I use -P option to specify 3306 port, it's OK.

Or use links. While it is rather unpleasant to update the PATH in a running environment, it's easy to recreate a link to a new version of JRE/JDK. So:

• install different versions of JDK you want to use
• create a link to that folder either by junction or by built-in mklink command
• set the PATH to the link
• If other version of java is to be used, delete the link, create a new one, PATH/JAVA_HOME/hardcoded scripts remain untouched

select DATE(field) from table;

select value: 2020-12-15

First, open the terminal.

Then, type

cd ~
touch .sure
chmod 700 .sure

Next, open .sure and paste this inside.

#!/bin/bash --init-file

alias n='Taskkill /IM %Terminal% /f'
echo ''
echo 'Are you sure? Answer y or n.'
echo ''

After that, close the file.

~/.sure ; ENTER COMMAND HERE

This will give you a prompt of are you sure before continuing the command.

My use case is similar, except that I want a log cleanup event to run at 2am every night. As I said in the comment above, the DAY_HOUR doesn't work for me. In my case I don't really mind potentially missing the first day (and, given it is to run at 2am then 2am tomorrow is almost always the next 2am) so I use:

CREATE EVENT applog_clean_event

I'm an async novice, so I can't tell you definitively what is happening here. I suspect that there's a mismatch in the method execution expectations, even though you are using tasks internally in the methods. I think you'd get the results you are expecting if you changed Print to return a Task<string>:

private static string Send(int id)
{
    Task<HttpResponseMessage> responseTask = client.GetAsync("aaaaa");
    Task<string> result;
    responseTask.ContinueWith(x => result = Print(x));
    result.Wait();
    responseTask.Wait(); // There's likely a better way to wait for both tasks without doing it in this awkward, consecutive way.
    return result.Result;
}

private static Task<string> Print(Task<HttpResponseMessage> httpTask)
{
    Task<string> task = httpTask.Result.Content.ReadAsStringAsync();
    string result = string.Empty;
    task.ContinueWith(t =>
    {
        Console.WriteLine("Result: " + t.Result);
        result = t.Result;
    });
    return task;
}

Three important steps - How to Task Schedule an excel.xls(m) file

simply:

1. make sure the .vbs file is correct
2. set the Action tab correctly in Task Scheduler
3. don't turn on "Run whether user is logged on or not"

IN MORE DETAIL...

1. Here is an example .vbs file:

`

'   a .vbs file is just a text file containing visual basic code that has the extension renamed from .txt  to .vbs

'Write Excel.xls  Sheet's full path here
strPath = "C:\RodsData.xlsm" 

'Write the macro name - could try including module name
strMacro = "Update" '    "Sheet1.Macro2" 

'Create an Excel instance and set visibility of the instance
Set objApp = CreateObject("Excel.Application") 
objApp.Visible = True   '   or False 

'Open workbook; Run Macro; Save Workbook with changes; Close; Quit Excel
Set wbToRun = objApp.Workbooks.Open(strPath) 
objApp.Run strMacro     '   wbToRun.Name & "!" & strMacro 
wbToRun.Save 
wbToRun.Close 
objApp.Quit 

'Leaves an onscreen message!
MsgBox strPath & " " & strMacro & " macro and .vbs successfully completed!",         vbInformation 
'

`

2. In the Action tab (Task Scheduler):

set Program/script: = C:\Windows\System32\cscript.exe

set Add arguments (optional): = C:\MyVbsFile.vbs

3. Finally, don't turn on "Run whether user is logged on or not".

That should work.

If you're willing to transmit some data and that you don't need to be secured (any public infos) you can use a CORS proxy, it's very easy, you'll not have to change anything in your code or in server side (especially of it's not your server like the Yahoo API or OpenWeather). I've used it to fetch JSON files with an XMLHttpRequest and it worked fine.

That's the platform toolset for VS2015. You uninstalled it, therefore it is no longer available.

To change your Platform Toolset:

1. Right click your project, go to Properties.
2. Under Configuration Properties, go to General.
3. Change your Platform Toolset to one of the available ones.

If you want to be able to handle an error instead of blindly exiting, instead of using set -e, use a trap on the ERR pseudo signal.

#!/bin/bash
f () {
    errorCode=$? # save the exit code as the first thing done in the trap function
    echo "error $errorCode"
    echo "the command executing at the time of the error was"
    echo "$BASH_COMMAND"
    echo "on line ${BASH_LINENO[0]}"
    # do some error handling, cleanup, logging, notification
    # $BASH_COMMAND contains the command that was being executed at the time of the trap
    # ${BASH_LINENO[0]} contains the line number in the script of that command
    # exit the script or return to try again, etc.
    exit $errorCode  # or use some other value or do return instead
}
trap f ERR
# do some stuff
false # returns 1 so it triggers the trap
# maybe do some other stuff

Other traps can be set to handle other signals, including the usual Unix signals plus the other Bash pseudo signals RETURN and DEBUG.

// Select 1 from table_name will return false if the table does not exist.
$val = mysql_query('select 1 from `table_name` LIMIT 1');

if($val !== FALSE)
{
   //DO SOMETHING! IT EXISTS!
}
else
{
    //I can't find it...
}

Admittedly, it is more Pythonic than of the PHP idiom, but on the other hand, you don't have to worry about dealing with a copious amount of extra data.

Edit

So, this answer has been marked down at least twice as of the time I am writing this message. Assuming that I had made some gargantuan error, I went and I ran some benchmarks, and this is what I found that my solution is over 10% faster than the nearest alternative when the table does not exist, and it over 25% faster when the table does exist:

:::::::::::::::::::::::::BEGINNING NON-EXISTING TABLE::::::::::::::::::::::::::::::
23.35501408577 for bad select
25.408507823944 for select from schema num rows -- calls mysql_num_rows on select... from information_schema.
25.336688995361 for select from schema fetch row -- calls mysql_fetch_row on select... from information_schema result
50.669058799744 for SHOW TABLES FROM test
:::::::::::::::::::::::::BEGINNING EXISTING TABLE::::::::::::::::::::::::::::::
15.293519973755 for good select
20.784908056259 for select from schema num rows
21.038464069366 for select from schema fetch row
50.400309085846 for SHOW TABLES FROM test

I tried running this against DESC, but I had a timeout after 276 seconds (24 seconds for my answer, 276 to fail to complete the description of a non existing table).

For good measure, I am benchmarking against a schema with only four tables in it and this is an almost fresh MySQL install (this is the only database so far). To see the export, look here.

AND FURTHERMORE

This particular solution is also more database independent as the same query will work in PgSQL and Oracle.

FINALLY

mysql_query() returns FALSE for errors that aren't "this table doesn't exist".

If you need to guarantee that the table doesn't exist, use mysql_errno() to get the error code and compare it to the relevant MySQL errors.

There’s a new HTML5 approach to this, the formaction attribute:

<button type="submit" formaction="/action_one">First action</button>
<button type="submit" formaction="/action_two">Second action</button>

Apparently this does not work in IE9 and earlier, but for other browsers you should be fine (see: w3schools.com HTML <button> formaction Attribute).

Personally, I generally use Javascript to submit forms remotely (for faster perceived feedback) with this approach as backup. Between the two, the only people not covered are IE<9 with Javascript disabled.

Of course, this may be inappropriate if you’re basically taking the same action server-side regardless of which button was pushed, but often if there are two user-side actions available then they will map to two server-side actions as well.

Edit: As noted by Pascal_dher in the comments, this attribute is also available on the <input> tag as well.

List comp:

results = [x for x in (do_action(element) for element in somelist) if check(element)]

I know it's very late for this one... But here is a (not so simple) oneliner to get what you were looking for:

git show-branch --all 2>/dev/null | grep -E "\[$(git branch | grep -E '^\*' | awk '{ printf $2 }')" | tail -n+2 | sed -E "s/^[^\[]*?\[/[/"

• We are listing commits with branch name and relative positions to actual branch states with git show-branch (sending the warnings to /dev/null).
• Then we only keep those with our branch name inside the bracket with grep -E "\[$BRANCH_NAME".
• Where actual $BRANCH_NAME is obtained with git branch | grep -E '^\*' | awk '{ printf $2 }' (the branch with a star, echoed without that star).
• From our results, we remove the redundant line at the beginning with tail -n+2.
• And then, we fianlly clean up the output by removing everything preceding [$BRANCH_NAME] with sed -E "s/^[^\[]*?\[/[/".

In my case the problem occurred due to closing my PC while visual studio were remain open, so in result csproj.user file saved empty. Thankfully i have already backup, so i just copied all xml from csproj.user and paste in my affected project csproj.user file ,so it worked perfectly.

This file just contain building device info and some more.

In my case, I noticed this behavior when the box was out of memory (RAM) I went to Jenkins -> Manage Jenkins -> Manage Nodes and found an out of memory exception. I just freed up some memory on the machine and the jobs started to go into the executors.

another alternative is to use a form replacement script/library. They usually hide the original element and replace them with a div or span, which you can style in whatever way you like.

Examples are:

http://customformelements.net (based on mootools) http://www.htmldrive.net/items/show/481/jQuery-UI-Radiobutton-und-Checkbox-Replacement.html

A more "duck typing" way is to use respond_to? this way "integer-like" or "string-like" classes can also be used

if(s.respond_to?(:match) && s.match(".com")){
  puts "It's a .com"
else
  puts "It's not"
end

Vartec's answer doesn't read all lines, so I made a version that did:

def run_command(command):
    p = subprocess.Popen(command,
                         stdout=subprocess.PIPE,
                         stderr=subprocess.STDOUT)
    return iter(p.stdout.readline, b'')

Usage is the same as the accepted answer:

command = 'mysqladmin create test -uroot -pmysqladmin12'.split()
for line in run_command(command):
    print(line)

I have a strong suspicion that all of the answers here are nothing more than hacks. I've tried them all and many others, but without any reliable conclusion as there is always some sort of stupid issue. I for one cannot rely on inconsistent results. If you look at the official Android API documentation for Fragments you will see Google clearly states the following:

Call startActivityForResult(Intent, int) from the fragment's containing Activity.

See: Android Fragment API

So, it would seem that the most correct and reliable approach would be to actually call startActivityForResult() from the hosting activity and also handle the resulting onActivityResult() from there.

Sometimes we have to use loops, for example, when we don't know how many iterations we need to get the result. Take while loops as an example. Below are methods you absolutely should avoid:

a=numeric(0)
b=1
system.time(
  {
    while(b<=1e5){
      b=b+1
      a<-c(a,pi)
    }
  }
)
# user  system elapsed 
# 13.2     0.0    13.2 

a=numeric(0)
b=1
system.time(
  {
    while(b<=1e5){
      b=b+1
      a<-append(a,pi)
    }
  }
)
# user  system elapsed 
# 11.06    5.72   16.84 

These are very inefficient because R copies the vector every time it appends.

The most efficient way to append is to use index. Note that this time I let it iterate 1e7 times, but it's still much faster than c.

a=numeric(0)
system.time(
  {
    while(length(a)<1e7){
      a[length(a)+1]=pi
    }
  }
)
# user  system elapsed 
# 5.71    0.39    6.12  

This is acceptable. And we can make it a bit faster by replacing [ with [[.

a=numeric(0)
system.time(
  {
    while(length(a)<1e7){
      a[[length(a)+1]]=pi
    }
  }
)
# user  system elapsed 
# 5.29    0.38    5.69   

Maybe you already noticed that length can be time consuming. If we replace length with a counter:

a=numeric(0)
b=1
system.time(
  {
    while(b<=1e7){
      a[[b]]=pi
      b=b+1
    }
  }
)
# user  system elapsed 
# 3.35    0.41    3.76

As other users mentioned, pre-allocating the vector is very helpful. But this is a trade-off between speed and memory usage if you don't know how many loops you need to get the result.

a=rep(NaN,2*1e7)
b=1
system.time(
  {
    while(b<=1e7){
      a[[b]]=pi
      b=b+1
    }
    a=a[!is.na(a)]
  }
)
# user  system elapsed 
# 1.57    0.06    1.63 

An intermediate method is to gradually add blocks of results.

a=numeric(0)
b=0
step_count=0
step=1e6
system.time(
  {
    repeat{
      a_step=rep(NaN,step)
      for(i in seq_len(step)){
        b=b+1
        a_step[[i]]=pi
        if(b>=1e7){
          a_step=a_step[1:i]
          break
        }
      }
      a[(step_count*step+1):b]=a_step
      if(b>=1e7) break
      step_count=step_count+1
    }
  }
)
#user  system elapsed 
#1.71    0.17    1.89

ls -alR|awk '{ if ($5 > max) {max=$5;ff=$9}} END {print max "\t" ff;}'

First of all you missed ScriptService attribute to add in webservice.

[ScriptService]

After then try following method to call webservice via JSON.

        var webAddr = "http://Domain/VBRService.asmx/callJson";
        var httpWebRequest = (HttpWebRequest)WebRequest.Create(webAddr);
        httpWebRequest.ContentType = "application/json; charset=utf-8";
        httpWebRequest.Method = "POST";            

        using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
        {
            string json = "{\"x\":\"true\"}";

            streamWriter.Write(json);
            streamWriter.Flush();
        }

        var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
        using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
        {
            var result = streamReader.ReadToEnd();
            return result;
        }

I tried updating and it didn't work. Finally , I had to completely remove (manually )cocoapods, cocoapods-core , cocoapods-try.. and any other package used by cocoapods. Use this terminal command to list all the packages:

gem list --local | grep cocoapods

After that , I also deleted ./cocoapods folder from the user's root folder.

For Bootstrap 4, you can simply use the class helper:

<table class="table">
  <thead>
    <tr>
      <td class="w-25">Col 1</td>
      <td class="w-25">Col 2</td>
      <td class="w-25">Col 3</td>
      <td class="w-25">Col 4</td>
    </tr>
  </thead>
  <tbody>
    <tr>
      ...

I would use spans or float the div left. The only problem with floating is that you have to clear the float afterwards or the containing div must have the overflow style set to auto

An absolute xpath in HTML DOM starts with /html e.g.

/html/body/div[5]/div[2]/div/div[2]/div[2]/h2[1]

and a relative xpath finds the closed id to the dom element and generates xpath starting from that element e.g.

.//*[@id='answers']/h2[1]/a[1]

You can use firepath (firebug) for generating both types of xpaths

It won't make any difference which xpath you use in selenium, the former may be faster than the later one (but it won't be observable)

Absolute xpaths are prone to more regression as slight change in DOM makes them invalid or refer to a wrong element

You're not actually using promises here. Parse lets you use callbacks or promises; your choice.

To use promises, do the following:

query.find().then(function() {
    console.log("success!");
}, function() {
    console.log("error");
});

Now, to execute stuff after the promise is complete, you can just execute it inside the promise callback inside the then() call. So far this would be exactly the same as regular callbacks.

To actually make good use of promises is when you chain them, like this:

query.find().then(function() {
    console.log("success!");

    return new Parse.Query(Obj).get("sOmE_oBjEcT");
}, function() {
    console.log("error");
}).then(function() {
    console.log("success on second callback!");
}, function() {
    console.log("error on second callback");
});

And this is the perfect solution that will also remove XSI elements. (If you remove the xmlns and don't remove XSI, .Net shouts at you...)

string xml = node.OuterXml;
//Regex below finds strings that start with xmlns, may or may not have :and some text, then continue with =
//and ", have a streach of text that does not contain quotes and end with ". similar, will happen to an attribute
// that starts with xsi.
string strXMLPattern = @"xmlns(:\w+)?=""([^""]+)""|xsi(:\w+)?=""([^""]+)""";
xml = Regex.Replace(xml, strXMLPattern, "");

if you want infos from the actual running batchfile, try this :

@echo off
set myNameFull=%0
echo myNameFull     %myNameFull%
set myNameShort=%~n0
echo myNameShort    %myNameShort%
set myNameLong=%~nx0
echo myNameLong     %myNameLong%
set myPath=%~dp0
echo myPath         %myPath%
set myLogfileWpath=%myPath%%myNameShort%.log
echo myLogfileWpath %myLogfileWpath%

more samples? C:> HELP CALL

%0 = parameter 0 = batchfile %1 = parameter 1 - 1st par. passed to batchfile... so you can try that stuff (e.g. "~dp") between 1st (e.g. "%") and last (e.g. "1") also for parameters

Flash still has the ASO file, which is the compiled byte code for your classes. On Windows, you can see the ASO files here:

C:\Documents and Settings\username\Local Settings\Application Data\Adobe\Flash CS4\en\Configuration\Classes\aso

On a Mac, the directory structure is similar in /Users/username/Library/Application Support/

You can remove those files by hand, or in Flash you can select Control->Delete ASO files to remove them.

To use a MySQL AUTO_INCREMENT column, you are supposed to use an IDENTITY strategy:

@Id @GeneratedValue(strategy=GenerationType.IDENTITY)
private Long id;

Which is what you'd get when using AUTO with MySQL:

@Id @GeneratedValue(strategy=GenerationType.AUTO)
private Long id;

Which is actually equivalent to

@Id @GeneratedValue
private Long id;

In other words, your mapping should work. But Hibernate should omit the id column in the SQL insert statement, and it is not. There must be a kind of mismatch somewhere.

Did you specify a MySQL dialect in your Hibernate configuration (probably MySQL5InnoDBDialect or MySQL5Dialect depending on the engine you're using)?

Also, who created the table? Can you show the corresponding DDL?

Follow-up: I can't reproduce your problem. Using the code of your entity and your DDL, Hibernate generates the following (expected) SQL with MySQL:

insert 
into
    Operator
    (active, password, username) 
values
    (?, ?, ?)

Note that the id column is absent from the above statement, as expected.

To sum up, your code, the table definition and the dialect are correct and coherent, it should work. If it doesn't for you, maybe something is out of sync (do a clean build, double check the build directory, etc) or something else is just wrong (check the logs for anything suspicious).

Regarding the dialect, the only difference between MySQL5Dialect or MySQL5InnoDBDialect is that the later adds ENGINE=InnoDB to the table objects when generating the DDL. Using one or the other doesn't change the generated SQL.

The method you want is toInt() -- you have to be a little careful, since the toInt() returns an optional Int.

let stringNumber = "1234"
let numberFromString = stringNumber.toInt()
// numberFromString is of type Int? with value 1234

let notANumber = "Uh oh"
let wontBeANumber = notANumber.toInt()
// wontBeANumber is of type Int? with value nil

There are three options:

1. Chain exclude and filter

   results = Model.objects.exclude(a=True).filter(x=5)
   

2. Use Q() objects and the ~ operator

   from django.db.models import Q
   object_list = QuerySet.filter(~Q(a=True), x=5)
   

3. Register a custom lookup function

   from django.db.models import Lookup
   from django.db.models import Field
   
   @Field.register_lookup
   class NotEqual(Lookup):
       lookup_name = 'ne'
   
       def as_sql(self, compiler, connection):
           lhs, lhs_params = self.process_lhs(compiler, connection)
           rhs, rhs_params = self.process_rhs(compiler, connection)
           params = lhs_params + rhs_params
           return '%s <> %s' % (lhs, rhs), params
   

   Which can the be used as usual:

   results = Model.objects.exclude(a=True, x__ne=5)
   

I was getting this problem with a maven project using the eclipse IDE. I changed the 'Order and Export' in the project's build path putting the Maven dependencies first and the error disappeared. I guess it's because the eclipse IDE was initially building my application source before loading the Maven libraries.

Top Answer from Jon Adams

Here is how to implement this for the PowerShell folks

$IncommingPath = "F:\WebContent"
$Acl = Get-Acl $IncommingPath
$Ar = New-Object  system.security.accesscontrol.filesystemaccessrule("IIS AppPool\DefaultAppPool","FullControl","ContainerInherit, ObjectInherit", "None", "Allow")
$Acl.SetAccessRule($Ar)
Set-Acl $IncommingPath $Acl

Suppose for some reason Ctrl+Z is also not working, go to another terminal, find the process id (using ps) and run:

kill -SIGSTOP PID 
kill -SIGCONT PID

SIGSTOP will suspend the process and SIGCONT will resume the process, in background. So now, closing both your terminals won't stop your process.

While I would recommend against this.

But you can use shutdown as client if the target machine has remote shutdown enabled and is in the same workgroup.

Example:

shutdown.exe /s /m \\<target-computer-name> /t 00

replacing <target-computer-name> with the URI for the target machine,

Otherwise, if you want to trigger this through Apache, you'll need to configure the batch script as a CGI script by putting AddHandler cgi-script .bat and Options +ExecCGI into either a local .htaccess file or in the main configuration for your Apache install.

Then you can just call the .bat file containing the shutdown.exe command from your browser.

Use Below Code:

private boolean isNetworkAvailable() {
  ConnectivityManager connectivityManager 
      = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
  NetworkInfo activeNetworkInfo = connectivityManager.getActiveNetworkInfo();
  return activeNetworkInfo != null && activeNetworkInfo.isConnected();
}

if isNetworkAvailable() returns true then internet connection available, otherwise internet connection not available

Here need to add below uses-permission in your application Manifest file

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

When you checked a checkbox like;

$('.className').attr('checked', 'checked')

it might not be enough. You should also call the function below;

$('.className').prop('checked', 'true')

Especially when you removed the checkbox checked attribute.

My absolute favorite description of the difference between unchecked and checked exceptions is provided by the Java Tutorial trail article, "Unchecked Exceptions - the Controversy" (sorry to get all elementary on this post - but, hey, the basics are sometimes the best):

Here's the bottom line guideline: If a client can reasonably be expected to recover from an exception, make it a checked exception. If a client cannot do anything to recover from the exception, make it an unchecked exception

The heart of "what type of exception to throw" is semantic (to some degree) and the above quote provides and excellent guideline (hence, I am still blown away by the notion that C# got rid of checked exceptions - particularly as Liskov argues for their usefulness).

The rest then becomes logical: to which exceptions does the compiler expect me to respond, explicitly? The ones from which you expect client to recover.

I ran into this on Python 3 and found this question (and solution). When opening a file, Python 3 supports the encoding keyword to automatically handle the encoding.

Without it, the BOM is included in the read result:

>>> f = open('file', mode='r')
>>> f.read()
'\ufefftest'

Giving the correct encoding, the BOM is omitted in the result:

>>> f = open('file', mode='r', encoding='utf-8-sig')
>>> f.read()
'test'

Just my 2 cents.

One can also nullify parent's line height:

#wrapper {
  line-height: 0;
}

All fixes: http://jsfiddle.net/FaPFv/

you can try this.

data_you_need=pd.DataFrame()
for infile in glob.glob("*.xlsx"):
    data = pandas.read_excel(infile)
    data_you_need=data_you_need.append(data,ignore_index=True)

I hope it can help.

The easiest way would be to set the value of the form element. If you're using jQuery (which I would highly recommend) you can do this easily with

$('#element-id').val('')

For all input elements in the form this may work (i've never tried it)

$('#form-id').children('input').val('')

Note that .children will only find input elements one level down. If you need to find grandchildren or such .find() should work.

There may be a better way however this should work for you.

CASE case_value
    WHEN when_value THEN statements
    [WHEN when_value THEN statements]
    ELSE statements
END 

Or:

CASE
WHEN <search_condition> THEN statements
[WHEN <search_condition> THEN statements] 
ELSE statements
END 

here CASE is an expression in 2nd scenario search_condition will evaluate and if no search_condition is equal then execute else

SELECT
   CASE course_enrollment_settings.base_price
    WHEN course_enrollment_settings.base_price = 0      THEN 1

should be

SELECT
   CASE 
    WHEN course_enrollment_settings.base_price = 0      THEN 1

I would first create a DataTable with the columns that you require, then populate it via Linq-to-XML.

You could use a Select query to create an object that represents each row, then use the standard approach for creating DataRows for each item ...

class Quest
{
    public string Answer1;
    public string Answer2;
    public string Answer3;
    public string Answer4;
}

public static void Main()
{
    var doc = XDocument.Load("filename.xml");

    var rows = doc.Descendants("QuestId").Select(el => new Quest
    {
        Answer1 = el.Element("Answer1").Value,
        Answer2 = el.Element("Answer2").Value,
        Answer3 = el.Element("Answer3").Value,
        Answer4 = el.Element("Answer4").Value,
    });

    // iterate over the rows and add to DataTable ...

}

I had the same issues due to corrupted or maybe outdated intellij files. Before updating to 14.0.2 I had a perfectly working project with CORRECTLY named packages and file hierarchies.

After the update, maven compilations worked without a hitch but Intellij was reporting the said error on a specific package (other packages with similar characteristics were not affected).

I didn't bother to investigate much further , but I deleted my .iml files and .idea folders, invalidated caches, restarted the IDE, and reopened the project, relying on my maven configuration.

NOTE: This, effectively deletes run and debug configurations!

Maybe someone who understands the intellij workspace files could comment on this?

Another comment for those searching into this further: Refactoring in SC managed projects can leave behind dust -- I happen to have an "old" folder which has repetitions of the current package structure. If the .iml or .idea files have any reference to these packages it's likely that intellij could get confused with references to old packages. Good luck, fellow StackExchangers.

Update: I deleted some files in a referenced maven project and the quirk has returned. So, my post is by no means a final answer.

There is a simple solution.

MySql 5.7 comes with anonymous user so you need to reconfigure MySQL server.

You can do that with this command

try to find temp pass:

grep 'temporary password' /var/log/mysqld.log

then:

sudo mysql_secure_installation

If you want to use \newcommand, you can also include \usepackage{xspace} and define command by \newcommand{\newCommandName}{text to insert\xspace}. This can allow you to just use \newCommandName rather than \newCommandName{}.

Cannot comment anymore but voted it up and wanted to let folks know that " works very well for the xml config files when forming regex expressions for RegexTransformer in Solr like so: regex=".*img src="(.*)".*" using the escaped version instead of double-quotes.
