Opacity changes the context of your z-index, as does the static positioning. Either add opacity to the element that doesn't have it or remove it from the element that does. You'll also have to either make both elements static positioned or specify relative or absolute position. Here's some background on contexts: http://philipwalton.com/articles/what-no-one-told-you-about-z-index/

For me this worked.

$ sudo apt-get install openjfx

you can use the views *_DEPENDENCIES, for example:

SELECT owner, NAME
  FROM dba_dependencies
 WHERE referenced_owner = :table_owner
   AND referenced_name = :table_name
   AND TYPE IN ('PACKAGE', 'PACKAGE BODY')

Encoding flash video is actually very easy with ffmpeg. You can use one command to convert from just about any video format, ffmpeg is smart enough to figure the rest out, and it'll use every processor on your machine. Invoking it is easy:

ffmpeg -i input.avi output.flv

ffmpeg will guess at the bitrate you want, but if you'd like to specify one, you can use the -b option, so -b 500000 is 500kbps for example. There's a ton of options of course, but I generally get good results without much tinkering. This is a good place to start if you're looking for more options: video options.

You don't need a special web server to show flash video. I've done just fine by simply pushing .flv files up to a standard web server, and linking to them with a good swf player, like flowplayer.

WMVs are fine if you can be sure that all of your users will always use [a recent, up to date version of] Windows only, but even then, Flash is often a better fit for the web. The player is even extremely skinnable and can be controlled with javascript.

See the Android documentation on controlling the emulator; it's Ctrl + F11 / Ctrl + F12.

On ThinkPad running Ubuntu, you may try CTRL + Left Arrow Key or Right Arrow Key

You put your image in resources folder and use follow code:

JButton btn = new JButton("");
btn.setIcon(new ImageIcon(Class.class.getResource("/resources/img.png")));

Use the CSS property visibility and set it to hidden.

Some practical examples, somewhat connected to large scale development where Gerrit is used for review and delivery integration:

I merge when I uplift my feature branch to a fresh remote master. This gives minimal uplift work and it's easy to follow the history of the feature development in for example gitk.

git fetch
git checkout origin/my_feature
git merge origin/master
git commit
git push origin HEAD:refs/for/my_feature

I merge when I prepare a delivery commit.

git fetch
git checkout origin/master
git merge --squash origin/my_feature
git commit
git push origin HEAD:refs/for/master

I rebase when my delivery commit fails integration for whatever reason, and I need to update it towards a fresh remote master.

git fetch
git fetch <gerrit link>
git checkout FETCH_HEAD
git rebase origin/master
git push origin HEAD:refs/for/master

Python installation folder > Lib > idlelib > idle.pyw

Double click on it and you're good to go.

I'm not sure if you need perfomance for doing this, but here is the fastest method to convert byte[] to hex string that I can think of :

static readonly char[] hexchar = new char[] { '0', '1', '2', '3', '4', '5', '6', '7', '8', '9', 'A', 'B', 'C', 'D', 'E', 'F' };
public static string HexStr(byte[] data, int offset, int len, bool space = false)
{
    int i = 0, k = 2;
    if (space) k++;
    var c = new char[len * k];
    while (i < len)
    {
        byte d = data[offset + i];
        c[i * k] = hexchar[d / 0x10];
        c[i * k + 1] = hexchar[d % 0x10];
        if (space && i < len - 1) c[i * k + 2] = ' ';
        i++;
    }
    return new string(c, 0, c.Length);
}

If you're talking about last time the table was updated in terms of its structured has changed (new column added, column changed etc.) - use this query:

SELECT name, [modify_date] FROM sys.tables

If you're talking about DML operations (insert, update, delete), then you either need to persist what that DMV gives you on a regular basis, or you need to create triggers on all tables to record that "last modified" date - or check out features like Change Data Capture in SQL Server 2008 and newer.

log2j now has support to delete old logs.

Take a look at DefaultRolloverStrategy tag and at a snippet below.

It

• creates up to 10 archives on the same day,

• will parse the ${baseDir} directory that you define under the Properties tag at max depth of 2 with log filename matching "app-*.log.gz"

• delete logs older than 7 days but keep the most recent 5 logs if your most recent 5 logs are older than 7 days.

  <DefaultRolloverStrategy max="10">
    <Delete basePath="${baseDir}" maxDepth="2">
      <IfFileName glob="*/app-*.log.gz">
        <IfLastModified age="7d">
          <IfAny>
            <IfAccumulatedFileCount exceeds="5" />
          </IfAny>
        </IfLastModified>
      </IfFileName>
    </Delete>
  </DefaultRolloverStrategy>
  

A good debug option is if you set:

<Configuration status="trace">

and use testMode Option like this:

        <DefaultRolloverStrategy>
          <Delete basePath="${baseDir}" testMode="true">
            <IfFileName glob="*.log" />
            <IfLastModified age="7d" />
          </Delete>
        </DefaultRolloverStrategy>
        

You can see in console log what files would get deleted without deleting the files right away.

declare @RangeWidth int

set @RangeWidth = 10

select
   Floor(Score/@RangeWidth) as LowerBound,
   Floor(Score/@RangeWidth)+@RangeWidth as UpperBound,

group by
   Floor(Score/@RangeWidth)

I found this implementation very easy to use. Also has a generous BSD-style license:

jsSHA: https://github.com/Caligatio/jsSHA

I needed a quick way to get the hex-string representation of a SHA-256 hash. It only took 3 lines:

var sha256 = new jsSHA('SHA-256', 'TEXT');
sha256.update(some_string_variable_to_hash);
var hash = sha256.getHash("HEX");

I am not an expert but try white-space:nowrap;

The white-space property is supported in all major browsers.

Note: The value "inherit" is not supported in IE7 and earlier. IE8 requires a !DOCTYPE. IE9 supports "inherit".

I was looking for something and I found this post. I post this code that managed many-to-many relationships in case someone needs it.

    var UserInRole = db.UsersInRoles.Include(u => u.UserProfile).Include(u => u.Roles)
    .Select (m => new 
    {
        UserName = u.UserProfile.UserName,
        RoleName = u.Roles.RoleName
    });

If you will not be needing the _id of the records I will recommend unsetting it when querying the DB which will enable you to print the returned records directly e.g

To unset the _id when querying and then print data in a loop you write something like this

records = mycollection.find(query, {'_id': 0}) #second argument {'_id':0} unsets the id from the query
for record in records:
    print(record)

You can have just one ng-view.

You can change its content in several ways: ng-include, ng-switch or mapping different controllers and templates through the routeProvider.

Here's an httplib solution that behaves like urllib2. You can just give it a URL and it just works. No need to mess about splitting up your URLs into hostname and path. This function already does that.

import httplib
import socket
def get_link_status(url):
  """
    Gets the HTTP status of the url or returns an error associated with it.  Always returns a string.
  """
  https=False
  url=re.sub(r'(.*)#.*$',r'\1',url)
  url=url.split('/',3)
  if len(url) > 3:
    path='/'+url[3]
  else:
    path='/'
  if url[0] == 'http:':
    port=80
  elif url[0] == 'https:':
    port=443
    https=True
  if ':' in url[2]:
    host=url[2].split(':')[0]
    port=url[2].split(':')[1]
  else:
    host=url[2]
  try:
    headers={'User-Agent':'Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:26.0) Gecko/20100101 Firefox/26.0',
             'Host':host
             }
    if https:
      conn=httplib.HTTPSConnection(host=host,port=port,timeout=10)
    else:
      conn=httplib.HTTPConnection(host=host,port=port,timeout=10)
    conn.request(method="HEAD",url=path,headers=headers)
    response=str(conn.getresponse().status)
    conn.close()
  except socket.gaierror,e:
    response="Socket Error (%d): %s" % (e[0],e[1])
  except StandardError,e:
    if hasattr(e,'getcode') and len(e.getcode()) > 0:
      response=str(e.getcode())
    if hasattr(e, 'message') and len(e.message) > 0:
      response=str(e.message)
    elif hasattr(e, 'msg') and len(e.msg) > 0:
      response=str(e.msg)
    elif type('') == type(e):
      response=e
    else:
      response="Exception occurred without a good error message.  Manually check the URL to see the status.  If it is believed this URL is 100% good then file a issue for a potential bug."
  return response

Here's my attempt to install .msi using msiexec in Administrative PowerShell.

I've made it 7 times for each of 2 drives, C: and D: (14 total) with different arguments in place of ARG and the same desirable path value.

Template: PS C:\WINDOWS\system32> msiexec /a D:\users\username\downloads\soft\publisher\softwarename\software.msi /passive ARG="D:\Soft\publisher\softwarename"

ARGs:

• TARGETDIR
  • Works OK-ish, but produces redundand ProgramFilesFolder (with an additional folders similar to the default installation path, e.g. D:\Soft\BlenderFoundation\Blender\ProgramFilesFolder\Blender Foundation\Blender\2.81\) and a copy of the .msi at the target folder.
• INSTALLDIR, INSTALLPATH, INSTALLFOLDER, INSTALLLOCATION, APPLICATIONFOLDER, APPDIR
  • When running on the same drive as set in the parameter: installs on this drive in a default folder (e.g. D:\Blender Foundation\Blender\2.81\)
  • When running from a differnet drive: seems to do nothing

import os
## first file in current dir (with full path)
file = os.path.join(os.getcwd(), os.listdir(os.getcwd())[0])
file
os.path.dirname(file) ## directory of file
os.path.dirname(os.path.dirname(file)) ## directory of directory of file
...

And you can continue doing this as many times as necessary...

Edit: from os.path, you can use either os.path.split or os.path.basename:

dir = os.path.dirname(os.path.dirname(file)) ## dir of dir of file
## once you're at the directory level you want, with the desired directory as the final path node:
dirname1 = os.path.basename(dir) 
dirname2 = os.path.split(dir)[1] ## if you look at the documentation, this is exactly what os.path.basename does.

Talk about making a mountain out of a mole hill. If you relax the requirement to make a float analog of the range function, and just create a list of floats that is easy to use in a for loop, the coding is simple and robust.

def super_range(first_value, last_value, number_steps):
    if not isinstance(number_steps, int):
        raise TypeError("The value of 'number_steps' is not an integer.")
    if number_steps < 1:
        raise ValueError("Your 'number_steps' is less than 1.")

    step_size = (last_value-first_value)/(number_steps-1)

    output_list = []
    for i in range(number_steps):
        output_list.append(first_value + step_size*i)
    return output_list

first = 20.0
last = -50.0
steps = 5

print(super_range(first, last, steps))

The output will be

[20.0, 2.5, -15.0, -32.5, -50.0]

Note that the function super_range is not limited to floats. It can handle any data type for which the operators +, -, *, and / are defined, such as complex, Decimal, and numpy.array:

import cmath
first = complex(1,2)
last = complex(5,6)
steps = 5

print(super_range(first, last, steps))

from decimal import *
first = Decimal(20)
last = Decimal(-50)
steps = 5

print(super_range(first, last, steps))

import numpy as np
first = np.array([[1, 2],[3, 4]])
last = np.array([[5, 6],[7, 8]])
steps = 5

print(super_range(first, last, steps))

The output will be:

[(1+2j), (2+3j), (3+4j), (4+5j), (5+6j)]
[Decimal('20.0'), Decimal('2.5'), Decimal('-15.0'), Decimal('-32.5'), Decimal('-50.0')]
[array([[1., 2.],[3., 4.]]),
 array([[2., 3.],[4., 5.]]),
 array([[3., 4.],[5., 6.]]),
 array([[4., 5.],[6., 7.]]),
 array([[5., 6.],[7., 8.]])]

I found that doing it in two relatively simple steps seemed to work quite well. The first css definition for ul sets the base indent that you want for the list as a whole. The second definition sets the indent value for each nested list item within it. In my case they are the same, but you can obviously pick whatever you want.

ul {
    margin-left: 1.5em;
}

ul > ul {
    margin-left: 1.5em;
}

In the case you want to download a single file, you can try the following command:

aws s3 cp s3://bucket/filename /path/to/dest/folder

I did some test:

When it's running:

$ /usr/lib/zookeeper/bin/zkServer.sh status
JMX enabled by default
Using config: /usr/lib/zookeeper/bin/../conf/zoo.cfg

When it's stopped:

$ zkServer status

Error contacting service. It is probably not running.

I'm not running on the same machine, but you get the idea.

Why did it take a lot of valgrind investigation to find this out! Just prove it to yourself with some simple code e.g.

std::vector<std::string> vec;

{
      std::string obj("hello world");
      vec.push_pack(obj);
}

std::cout << vec[0] << std::endl;  

If "hello world" is printed, the object must have been copied

Your second delegate is not a rewrite of the first in anonymous delegate (rather than lambda) format. Look at your conditions.

First:

x.ID == packageId || x.Parent.ID == packageId || x.Parent.Parent.ID == packageId

Second:

(x.ID == packageId) || (x.Parent != null && x.Parent.ID == packageId) || 
(x.Parent != null && x.Parent.Parent != null && x.Parent.Parent.ID == packageId)

The call to the lambda would throw an exception for any x where the ID doesn't match and either the parent is null or doesn't match and the grandparent is null. Copy the null checks into the lambda and it should work correctly.

Edit after Comment to Question

If your original object is not a List<T>, then we have no way of knowing what the return type of FindAll() is, and whether or not this implements the IQueryable interface. If it does, then that likely explains the discrepancy. Because lambdas can be converted at compile time into an Expression<Func<T>> but anonymous delegates cannot, then you may be using the implementation of IQueryable when using the lambda version but LINQ-to-Objects when using the anonymous delegate version.

This would also explain why your lambda is not causing a NullReferenceException. If you were to pass that lambda expression to something that implements IEnumerable<T> but not IQueryable<T>, runtime evaluation of the lambda (which is no different from other methods, anonymous or not) would throw a NullReferenceException the first time it encountered an object where ID was not equal to the target and the parent or grandparent was null.

Added 3/16/2011 8:29AM EDT

Consider the following simple example:

IQueryable<MyObject> source = ...; // some object that implements IQueryable<MyObject>

var anonymousMethod =  source.Where(delegate(MyObject o) { return o.Name == "Adam"; });    
var expressionLambda = source.Where(o => o.Name == "Adam");

These two methods produce entirely different results.

The first query is the simple version. The anonymous method results in a delegate that's then passed to the IEnumerable<MyObject>.Where extension method, where the entire contents of source will be checked (manually in memory using ordinary compiled code) against your delegate. In other words, if you're familiar with iterator blocks in C#, it's something like doing this:

public IEnumerable<MyObject> MyWhere(IEnumerable<MyObject> dataSource, Func<MyObject, bool> predicate)
{
    foreach(MyObject item in dataSource)
    {
        if(predicate(item)) yield return item;
    }
}

The salient point here is that you're actually performing your filtering in memory on the client side. For example, if your source were some SQL ORM, there would be no WHERE clause in the query; the entire result set would be brought back to the client and filtered there.

The second query, which uses a lambda expression, is converted to an Expression<Func<MyObject, bool>> and uses the IQueryable<MyObject>.Where() extension method. This results in an object that is also typed as IQueryable<MyObject>. All of this works by then passing the expression to the underlying provider. This is why you aren't getting a NullReferenceException. It's entirely up to the query provider how to translate the expression (which, rather than being an actual compiled function that it can just call, is a representation of the logic of the expression using objects) into something it can use.

An easy way to see the distinction (or, at least, that there is) a distinction, would be to put a call to AsEnumerable() before your call to Where in the lambda version. This will force your code to use LINQ-to-Objects (meaning it operates on IEnumerable<T> like the anonymous delegate version, not IQueryable<T> like the lambda version currently does), and you'll get the exceptions as expected.

TL;DR Version

The long and the short of it is that your lambda expression is being translated into some kind of query against your data source, whereas the anonymous method version is evaluating the entire data source in memory. Whatever is doing the translating of your lambda into a query is not representing the logic that you're expecting, which is why it isn't producing the results you're expecting.

I saw in at least one other place that people don't realize Date-Time takes in times as well, so I figured I'd share it here since it's really short to do so:

Get-Date # Following the OP's example, let's say it's Friday, March 12, 2010 9:00:00 AM
(Get-Date '22:00').AddDays(-1) # Thursday, March 11, 2010 10:00:00 PM

It's also the shortest way to strip time information and still use other parameters of Get-Date. For instance you can get seconds since 1970 this way (Unix timestamp):

Get-Date '0:00' -u '%s' # 1268352000

Or you can get an ISO 8601 timestamp:

Get-Date '0:00' -f 's' # 2010-03-12T00:00:00

Then again if you reverse the operands, it gives you a little more freedom with formatting with any date object:

'The sortable timestamp: {0:s}Z{1}Vs measly human format: {0:D}' -f (Get-Date '0:00'), "`r`n"
# The sortable timestamp: 2010-03-12T00:00:00Z
# Vs measly human format: Friday, March 12, 2010

However if you wanted to both format a Unix timestamp (via -u aka -UFormat), you'll need to do it separately. Here's an example of that:

'ISO 8601: {0:s}Z{1}Unix: {2}' -f (Get-Date '0:00'), "`r`n", (Get-Date '0:00' -u '%s')
# ISO 8601: 2010-03-12T00:00:00Z
# Unix: 1268352000

Hope this helps!

The other respondents are correct in describing the double leading and trailing underscores as a naming convention for "special" or "magic" methods.

While you can call these methods directly ([10, 20].__len__() for example), the presence of the underscores is a hint that these methods are intended to be invoked indirectly (len([10, 20]) for example). Most python operators have an associated "magic" method (for example, a[x] is the usual way of invoking a.__getitem__(x)).

For Some reason it is not working so we can do this by another way

just remove the line and add this :-

<a onclick="window.open ('http://www.foracure.org.au', ''); return false" href="javascript:void(0);"></a>

Good luck.

Just simply add or die(mysqli_error($db)); at the end of your query, this will print the mysqli error.

 mysqli_query($db,"INSERT INTO stockdetails (`itemdescription`,`itemnumber`,`sellerid`,`purchasedate`,`otherinfo`,`numberofitems`,`isitdelivered`,`price`) VALUES ('$itemdescription','$itemnumber','$sellerid','$purchasedate','$otherinfo','$numberofitems','$numberofitemsused','$isitdelivered','$price')") or die(mysqli_error($db));

As a side note I'd say you are at risk of mysql injection, check here How can I prevent SQL injection in PHP?. You should really use prepared statements to avoid any risk.

For an instance

Character.Gorgon gor = new Character.Gorgon();

Then do

gor instanceof Monster

For a Class instance do

Class<?> clazz = Character.Gorgon.class;
Monster.class.isAssignableFrom(clazz);

When your browser redirects the user to Google's oAuth page, are you passing as a parameter the redirect URI you want Google's server to return to with the token response? Setting a redirect URI in the console is not a way of telling Google where to go when a login attempt comes in, but rather it's a way of telling Google what the allowed redirect URIs are (so if someone else writes a web app with your client ID but a different redirect URI it will be disallowed); your web app should, when someone clicks the "login" button, send the browser to:

https://accounts.google.com/o/oauth2/auth?client_id=XXXXX&redirect_uri=http://localhost:8080/WEBAPP/youtube-callback.html&response_type=code&scope=https://www.googleapis.com/auth/youtube.upload

(the callback URI passed as a parameter must be url-encoded, btw).

When Google's server gets authorization from the user, then, it'll redirect the browser to whatever you sent in as the redirect_uri. It'll include in that request the token as a parameter, so your callback page can then validate the token, get an access token, and move on to the other parts of your app.

If you visit:

http://code.google.com/p/google-api-java-client/wiki/OAuth2#Authorization_Code_Flow

You can see better samples of the java client there, demonstrating that you have to override the getRedirectUri method to specify your callback path so the default isn't used.

The redirect URIs are in the client_secrets.json file for multiple reasons ... one big one is so that the oAuth flow can verify that the redirect your app specifies matches what your app allows.

If you visit https://developers.google.com/api-client-library/java/apis/youtube/v3 You can generate a sample application for yourself that's based directly off your app in the console, in which (again) the getRedirectUri method is overwritten to use your specific callbacks.

I'm not sure what jQuery api you're looking at, but you should only have to specify id.

$('#thumb').removeAttr('id');

I think the problem may be that you are not finding your element because of the "#" in your call to get it:

window.parent.document.getElementById('#target'); 

You only need the # if you are using jquery. Here it should be:

window.parent.document.getElementById('target'); 

You need to add this as the last line...

HttpContext.Current.Response.Cookies.Add(userid);

When you need to read the value of the cookie, you'd use a method similar to this:

    string cookieUserID= String.Empty;

    try
    {
        if (HttpContext.Current.Request.Cookies["userid"] != null)
        {
            cookieUserID = HttpContext.Current.Request.Cookies["userid"];
        }
    }
    catch (Exception ex)
    {
       //handle error
    }

    return cookieUserID;

here is revised one to treat null = null as equal

 private bool PublicInstancePropertiesEqual<T>(T self, T to, params string[] ignore) where T : class
        {
            if (self != null && to != null)
            {
                Type type = typeof(T);
                List<string> ignoreList = new List<string>(ignore);
                foreach (PropertyInfo pi in type.GetProperties(BindingFlags.Public | BindingFlags.Instance))
                {
                    if (!ignoreList.Contains(pi.Name))
                    {
                        object selfValue = type.GetProperty(pi.Name).GetValue(self, null);
                        object toValue = type.GetProperty(pi.Name).GetValue(to, null);
                        if (selfValue != null)
                        {
                            if (!selfValue.Equals(toValue))
                                return false;
                        }
                        else if (toValue != null)
                            return false;
                    }
                }
                return true;
            }
            return self == to;
        }

first, create a class to hold your parameters:

public class PkRk {
    public int pk { get; set; }
    public int rk { get; set; }
}

then, use the Html.Action passing the parameters:

Html.Action("PkRkAction", new { pkrk = new PkRk { pk=400, rk=500} })

and use in Controller:

public ActionResult PkRkAction(PkRk pkrk) {
    return PartialView(pkrk);
}

in my case it wasn't checked in xcode After installation process ,

you can do that as following : xcode -> Preferences and tap Locations then select , as the followng image

If you are doing this often then it is better to stove it away in a helper function:

def index_of(val, in_list):
    try:
        return in_list.index(val)
    except ValueError:
        return -1 

You were on the right track. IrfanView sets the background for transparency the same as the viewing color around the image.

You just need to re-open the image with IrfanView after changing the view color to white.

To change the viewing color in Irfanview go to:

Options > Properties/Settings > Viewing > Main window color

You can't have duplicate keys in a Map. You can rather create a Map<Key, List<Value>>, or if you can, use Guava's Multimap.

Multimap<Integer, String> multimap = ArrayListMultimap.create();
multimap.put(1, "rohit");
multimap.put(1, "jain");

System.out.println(multimap.get(1));  // Prints - [rohit, jain]

And then you can get the java.util.Map using the Multimap#asMap() method.

Adding to the solutions of others, I'd like to suggest using the plotly package for R, as this has worked well for me.

Below, I'm using the reformatted dataset suggested above, from xyz-tripplets to axis vectors x and y and a matrix z:

x <- 1:5/10
y <- 1:5
z <- x %o% y
z <- z + .2*z*runif(25) - .1*z

library(plotly)
plot_ly(x=x,y=y,z=z, type="surface")

The rendered surface can be rotated and scaled using the mouse. This works fairly well in RStudio.

You can also try it with the built-in volcano dataset from R:

plot_ly(z=volcano, type="surface")

This can be fixed by inserting the respective records in the Parent table first and then we can insert records in the Child table's respective column. Also check the data type and size of the column. It should be same as the parent table column,even the engine and collation should also be the same. TRY THIS! This is how I solved mine. Correct me if am wrong.

The correct way to do it for Material design is :

Style :

<style name="MyCheckBox" parent="Theme.AppCompat.Light">  
    <item name="colorControlNormal">@color/foo</item>
    <item name="colorControlActivated">@color/bar</item>
</style>  

Layout :

<CheckBox  
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:checked="true"
    android:text="Check Box"
    android:theme="@style/MyCheckBox"/>

It will preserve Material animations on Lollipop+.

libconfig is very easy, and what's better, it uses a pseudo json notation for better readability.

Easy to install on Ubuntu: sudo apt-get install libconfig++8-dev

and link: -lconfig++

In EF Core you can enter the command Remove-Migration in the package manager console after you've added your erroneous migration.

The console suggests you do so if your migration could involve a loss of data:

An operation was scaffolded that may result in the loss of data. Please review the migration for accuracy. To undo this action, use Remove-Migration.

Your worker method needs 'self' as a parameter, since it is a class method and not a function. Adding that should make it work fine.

This simple method will work for most cases, but would trip up over something like "u005Cu005C" which should decode to the string "\u0048" but would actually decode "H" as the first pass produces "\u0048" as the working string which then gets processed again by the while loop.

static final String decode(final String in)
{
    String working = in;
    int index;
    index = working.indexOf("\\u");
    while(index > -1)
    {
        int length = working.length();
        if(index > (length-6))break;
        int numStart = index + 2;
        int numFinish = numStart + 4;
        String substring = working.substring(numStart, numFinish);
        int number = Integer.parseInt(substring,16);
        String stringStart = working.substring(0, index);
        String stringEnd   = working.substring(numFinish);
        working = stringStart + ((char)number) + stringEnd;
        index = working.indexOf("\\u");
    }
    return working;
}

You could possibly use Reflection to do this. As far as I understand it, you could enumerate the properties of your class and set the values. You would have to try this out and make sure you understand the order of the properties though. Refer to this MSDN Documentation for more information on this approach.

For a hint, you could possibly do something like:

Record record = new Record();

PropertyInfo[] properties = typeof(Record).GetProperties();
foreach (PropertyInfo property in properties)
{
    property.SetValue(record, value);
}

Where value is the value you're wanting to write in (so from your resultItems array).

dd in command mode (after pressing escape) will cut the line, p in command mode will paste.

Update:

For a bonus, d and then a movement will cut the equivalent of that movement, so dw will cut a word, d<down-arrow> will cut this line and the line below, d50w will cut 50 words.

yy is copy line, and works like dd.

D cuts from cursor to end of line.

If you've used v (visual mode), you should try V (visual line mode) and <ctrl>v (visual block mode).

Same as @Sanchit Gupta.

in this part

if (results[0]) {
 var add= results[0].formatted_address ;
 var  value=add.split(",");
 count=value.length;
 country=value[count-1];
 state=value[count-2];
 city=value[count-3];
 x.innerHTML = "city name is: " + city;
}

just console the results array

if (results[0]) {
 console.log(results[0]);
 // choose from console whatever you need.
 var city = results[0].address_components[3].short_name;
 x.innerHTML = "city name is: " + city;
}

Answer to your first question is : both are similar,

Answer to your second question is: one-to-many --> a MAN(MAN table) may have more than one wife(WOMEN table) many-to-one --> more than one women have married one MAN.

Now if you want to relate this relation with two tables MAN and WOMEN, one MAN table row may have many relations with rows in the WOMEN table. hope it clear.

A simple way to see remote branches is:

git branch -r

To see local branches:

git branch -l

You can use Newtonsoft.Json, it's a dependency of Microsoft.AspNet.Mvc.ModelBinding which is a dependency of Microsoft.AspNet.Mvc. So, you don't need to add a dependency in your project.json.

#using Newtonsoft.Json
....
JsonConvert.DeserializeObject(json);

Note, using a WebAPI controller you don't need to deal with JSON.

UPDATE ASP.Net Core 3.0

Json.NET has been removed from the ASP.NET Core 3.0 shared framework.

You can use the new JSON serializer layers on top of the high-performance Utf8JsonReader and Utf8JsonWriter. It deserializes objects from JSON and serializes objects to JSON. Memory allocations are kept minimal and includes support for reading and writing JSON with Stream asynchronously.

To get started, use the JsonSerializer class in the System.Text.Json.Serialization namespace. See the documentation for information and samples.

To use Json.NET in an ASP.NET Core 3.0 project:

• Add a package reference to Microsoft.AspNetCore.Mvc.NewtonsoftJson
• Update ConfigureServices to call AddNewtonsoftJson().

    services.AddMvc()
        .AddNewtonsoftJson();

Read Json.NET support in Migrate from ASP.NET Core 2.2 to 3.0 Preview 2 for more information.

For me, I saw none of the MVC templates (except the bottom two), after installing Update 3 which installed all the Core stuff.

Solution

I downloaded most recent core preview...

It prompted me for "repair" and after it was done, bringing up VS indicated it was "Installing Templates" and they appeared!

Warning

Update 3 is a game changer in that the "preferred" way of doing things is to use dotnetcore. For example a console application now uses the new file stucture, other projects such as a Test Project still use the same folder structure as before. But MVC has changed. I'm not even sure what other "Web Developer Tools" work with dotnetcore right now.

As for 2018 there is still not a simple answer to the question of how to convert a PDF document to an image in C#; many libraries use Ghostscript licensed under AGPL and in most cases an expensive commercial license is required for production use.

A good alternative might be using the popular 'pdftoppm' utility which has a GPL license; it can be used from C# as command line tool executed with System.Diagnostics.Process. Popular tools are well known in the Linux world, but a windows build is also available.

If you don't want to integrate pdftoppm by yourself, you can use my PdfRenderer popular wrapper (supports both classic .NET Framework and .NET Core) - it is not free, but pricing is very affordable.

If you are using tcsh, then edit your ~/.cshrc file to include the lines:

setenv CLICOLOR 1
setenv LSCOLORS dxfxcxdxbxegedabagacad

Where, like Martin says, LSCOLORS specifies the color scheme you want to use.

To generate the LSCOLORS you want to use, checkout this site

You get the error because order[1] is undefined.

That error message means that somewhere in your code, an attempt is being made to access a property with some name (here it's "push"), but instead of an object, the base for the reference is actually undefined. Thus, to find the problem, you'd look for code that refers to that property name ("push"), and see what's to the left of it. In this case, the code is

if(parseInt(a[i].daysleft) > 0){ order[1].push(a[i]); }

which means that the code expects order[1] to be an array. It is, however, not an array; it's undefined, so you get the error. Why is it undefined? Well, your code doesn't do anything to make it anything else, based on what's in your question.

Now, if you just want to place a[i] in a particular property of the object, then there's no need to call .push() at all:

var order = [], stack = [];
for(var i=0;i<a.length;i++){
    if(parseInt(a[i].daysleft) == 0){ order[0] = a[i]; }
    if(parseInt(a[i].daysleft) > 0){ order[1] = a[i]; }
    if(parseInt(a[i].daysleft) < 0){ order[2] = a[i]; }
}

As per Android Documentation RecyclerView is the new way to organize the items in listview and to be displayed horizontally

Advantages:

1. Since by using Recyclerview Adapter, ViewHolder pattern is automatically implemented
2. Animation is easy to perform
3. Many more features

More Information about RecyclerView:

1. grokkingandroid.com
2. antonioleiva.com

Sample:

survivingwithandroid.com

Just add the below block to make the ListView to horizontal from vertical

Code-snippet

LinearLayoutManager layoutManager= new LinearLayoutManager(this,LinearLayoutManager.HORIZONTAL, false);
mRecyclerView = (RecyclerView) findViewById(R.id.recycler_view);
mRecyclerView.setLayoutManager(layoutManager);

Firefox 48.0 and selenium==2.53.6 work fine without any errors

To upgrade firefox on Ubuntu 14.04 only

sudo apt-get update
sudo apt-get upgrade firefox

The TextBoxFor is a newer MVC input extension introduced in MVC2.

The main benefit of the newer strongly typed extensions is to show any errors / warnings at compile-time rather than runtime.

See this page.

http://weblogs.asp.net/scottgu/archive/2010/01/10/asp-net-mvc-2-strongly-typed-html-helpers.aspx

Yes you can. You can even test it:

var i = 0;_x000D_
var timer = setInterval(function() {_x000D_
  console.log(++i);_x000D_
  if (i === 5) clearInterval(timer);_x000D_
  console.log('post-interval'); //this will still run after clearing_x000D_
}, 200);

In this example, this timer clears when i reaches 5.

$(".edgetoedge>li").removeClass("highlight");

The csh shell has never been known for its extensive ability to manipulate file handles in the redirection process.

You can redirect both standard output and error to a file with:

xxx >& filename

but that's not quite what you were after, redirecting standard error to the current standard output.

However, if your underlying operating system exposes the standard output of a process in the file system (as Linux does with /dev/stdout), you can use that method as follows:

xxx >& /dev/stdout

This will force both standard output and standard error to go to the same place as the current standard output, effectively what you have with the bash redirection, 2>&1.

Just keep in mind this isn't a csh feature. If you run on an operating system that doesn't expose standard output as a file, you can't use this method.

However, there is another method. You can combine the two streams into one if you send it to a pipeline with |&, then all you need to do is find a pipeline component that writes its standard input to its standard output. In case you're unaware of such a thing, that's exactly what cat does if you don't give it any arguments. Hence, you can achieve your ends in this specific case with:

xxx |& cat

Of course, there's also nothing stopping you from running bash (assuming it's on the system somewhere) within a csh script to give you the added capabilities. Then you can use the rich redirections of that shell for the more complex cases where csh may struggle.

Let's explore this in more detail. First, create an executable echo_err that will write a string to stderr:

#include <stdio.h>
int main (int argc, char *argv[]) {
    fprintf (stderr, "stderr (%s)\n", (argc > 1) ? argv[1] : "?");
    return 0;
}

Then a control script test.csh which will show it in action:

#!/usr/bin/csh

ps -ef ; echo ; echo $$ ; echo

echo 'stdout (csh)'
./echo_err csh

bash -c "( echo 'stdout (bash)' ; ./echo_err bash ) 2>&1"

The echo of the PID and ps are simply so you can ensure it's csh running this script. When you run this script with:

./test.csh >test.out 2>test.err

(the initial redirection is set up by bash before csh starts running the script), and examine the out/err files, you see:

test.out:
    UID     PID    PPID  TTY        STIME     COMMAND
    pax    5708    5364  cons0      11:31:14  /usr/bin/ps
    pax    5364    7364  cons0      11:31:13  /usr/bin/tcsh
    pax    7364       1  cons0      10:44:30  /usr/bin/bash

    5364

    stdout (csh)
    stdout (bash)
    stderr (bash)

test.err:
    stderr (csh)

You can see there that the test.csh process is running in the C shell, and that calling bash from within there gives you the full bash power of redirection.

The 2>&1 in the bash command quite easily lets you redirect standard error to the current standard output (as desired) without prior knowledge of where standard output is currently going.

Here is my (seemingly) robust, complete and (fairly) concise solution. It uses the minification compatible style (and the angular.module(NAME) access to your module).

angular.module('yourModuleName').run(["$rootScope", "$anchorScroll" , function ($rootScope, $anchorScroll) {
    $rootScope.$on("$locationChangeSuccess", function() {
                $anchorScroll();
    });
}]);

PS I found that the autoscroll thing had no effect whether set to true or false.

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

Following are 2 types of intents

1.Explicit Intents

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

2.Implicit Intents

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

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

Intent Filters

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

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

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

Following are 2 ways to define a filter

1.Manifest file

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

2.BroadCast Receiver

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

An alternative to @tv's answer:

var elems = $(parentSelect).nextAll(), count = elems.length;

elems.each( function(i) {
  $(this).fadeOut(200, function() { 
    $(this).remove(); 
    if (!--count) doMyThing();
  });
});

Note that .each() itself is synchronous — the statement that follows the call to .each() will be executed only after the .each() call is complete. However, asynchronous operations started in the .each() iteration will of course continue on in their own way. That's the issue here: the calls to fade the elements are timer-driven animations, and those continue at their own pace.

The solution above, therefore, keeps track of how many elements are being faded. Each call to .fadeOut() gets a completion callback. When the callback notices that it's counted through all of the original elements involved, some subsequent action can be taken with confidence that all of the fading has finished.

This is a four-year-old answer (at this point in 2014). A modern way to do this would probably involve using the Deferred/Promise mechanism, though the above is simple and should work just fine.

If you want to filter only items that are less than 7 days old then you just use

Filter

• Created

• is greater than or equal to

• [Today]-7

Note - the screenshot is incorrect.

[Today] is fully supported in view filters in 2007 and onwards (just keep the spaces out!) and you only need to muck around with calculated columns in 2003.

This should work:

git show branch:file

Where branch can be any ref (branch, tag, HEAD, ...) and file is the full path of the file. To export it you could use

git show branch:file > exported_file

You should also look at VonC's answers to some related questions:

• How to retrieve a single file from specific revision in Git?
• How to get just one file from another branch

UPDATE 2015-01-19:

Nowadays you can use relative paths with git show a1b35:./file.txt.

Even simpler is to use:

(?P<project_id>\w+|)

The "(a|b)" means a or b, so in your case it would be one or more word characters (\w+) or nothing.

So it would look like:

url(
    r'^project_config/(?P<product>\w+)/(?P<project_id>\w+|)/$',
    'tool.views.ProjectConfig',
    name='project_config'
),

Note that sort() operates on the array in place, so you only need to call

sort($a);
doSomething($a);

This will not work;

$a = sort($a);
doSomething($a);

Another possibility is to use the Maven Shade Plugin, e.g. to exclude a logging properties file used only locally in your IDE:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-shade-plugin</artifactId>
    <version>${maven-shade-plugin-version}</version>
    <executions>
        <execution>
            <phase>package</phase>
            <goals>
                <goal>shade</goal>
            </goals>
            <configuration>
                <filters>
                    <filter>
                        <artifact>*:*</artifact>
                        <excludes>
                            <exclude>log4j2.xml</exclude>
                        </excludes>
                    </filter>
                </filters>
            </configuration>
        </execution>
    </executions>
</plugin>

This will however exclude the files from every artifact, so it might not be feasible in every situation.

On Windows I usually use windows types. To use it you have to include <Windows.h>.

In this case uint32_t is UINT32 or just UINT.

All types definitions are here: http://msdn.microsoft.com/en-us/library/windows/desktop/aa383751%28v=vs.85%29.aspx

Well the easy answer would be: "your executable files are in the directories contained in your PATH variable" but that would not really find your executables and could miss a lot of executables anyway.

I don't know much about mac but I think "mdfind 'kMDItemContentType=public.unix-executable'" might miss stuff like interpreted scripts

If it's ok for you to find files with the executable bits set (regardless of whether they are actually executable) then it's fine to do

find . -type f -perm +111 -print

where supported the "-executable" option will make a further filter looking at acl and other permission artifacts but is technically not much different to "-pemr +111".

Maybe in the future find will support "-magic " and let you look explicitly for files with a specific magic id ... but then you would haveto specify to fine all the executable formats magic id.

I'm unaware of a technically correct easy way out on unix.

The DBHelper class is what handles the opening and closing of sqlite databases as well sa creation and updating, and a decent article on how it all works is here. When I started android it was very useful (however I've been objective-c lately, and forgotten most of it to be any use.

Instead of disabled, you could consider using readonly. With some extra CSS you can style the input so it looks like an disabled field.

There is actually another problem. The event change only triggers when the element looses focus, which is not logic considering an disabled field. Probably you are pushing data into this field from another call. To make this work you can use the event 'bind'.

$('form').bind('change', 'input', function () {
    console.log('Do your thing.');
});

SSH itself provides a means of communication, it does not know anything about directories. Since you can specify which remote command to execute (this is - by default - your shell), I'd start there.

There is no difference in working in both the concepts of assignment to unique_ptr.

int* intPtr = new int(3);
unique_ptr<int> uptr (intPtr);

is similar to

unique_ptr<int> uptr (new int(3));

Here unique_ptr automatically deletes the space occupied by uptr.

how pointers, declared in this way will be different from the pointers declared in a "normal" way.

If you create an integer in heap space (using new keyword or malloc), then you will have to clear that memory on your own (using delete or free respectively).

In the below code,

int* heapInt = new int(5);//initialize int in heap memory
.
.//use heapInt
.
delete heapInt;

Here, you will have to delete heapInt, when it is done using. If it is not deleted, then memory leakage occurs.

In order to avoid such memory leaks unique_ptr is used, where unique_ptr automatically deletes the space occupied by heapInt when it goes out of scope. So, you need not do delete or free for unique_ptr.

gcc and g++ are compiler-drivers of the GNU Compiler Collection (which was once upon a time just the GNU C Compiler).

Even though they automatically determine which backends (cc1 cc1plus ...) to call depending on the file-type, unless overridden with -x language, they have some differences.

The probably most important difference in their defaults is which libraries they link against automatically.

According to GCC's online documentation link options and how g++ is invoked, g++ is equivalent to gcc -xc++ -lstdc++ -shared-libgcc (the 1st is a compiler option, the 2nd two are linker options). This can be checked by running both with the -v option (it displays the backend toolchain commands being run).

As others have already mentioned your compile sdk version must match your support library's major version. This is however, also relevant for subprojects should you have any.

In case you do, you can set your subprojects compile sdk versions with the following script:

subprojects { subproject ->
afterEvaluate{
    if((subproject.plugins.hasPlugin('android') || subproject.plugins.hasPlugin('android-library'))) {
        android {
            compileSdkVersion rootProject.ext.compileSdkVersion
            buildToolsVersion rootProject.ext.buildToolsVersion
        }
      }
   }
}

Add this script in your root build.gradle file.

This is code I'm using to get ID for both iOS 5 and iOS 6, 7:

- (NSString *) advertisingIdentifier
{
    if (!NSClassFromString(@"ASIdentifierManager")) {
        SEL selector = NSSelectorFromString(@"uniqueIdentifier");
        if ([[UIDevice currentDevice] respondsToSelector:selector]) {
            return [[UIDevice currentDevice] performSelector:selector];
        }
    }
    return [[[ASIdentifierManager sharedManager] advertisingIdentifier] UUIDString];
}

I think a better way to solve this would be to use the datetime callable:

from datetime import datetime

date = models.DateField(default=datetime.now)

Note that no parenthesis were used. If you used parenthesis you would invoke the now() function just once (when the model is created). Instead, you pass the callable as an argument, thus being invoked everytime an instance of the model is created.

Credit to Django Musings. I've used it and works fine.

const a = {
  foods: {
    dinner: 'Pasta'
  }
}
let b = JSON.parse(JSON.stringify(a))
b.foods.dinner = 'Soup'
console.log(b.foods.dinner) // Soup
console.log(a.foods.dinner) // Pasta

Using JSON.stringify and JSON.parse is the best way. Because by using the spread operator we will not get the efficient answer when the json object contains another object inside it. we need to manually specify that.

You should define source code encoding, add this to the top of your script:

# -*- coding: utf-8 -*-

The reason why it works differently in console and in the IDE is, likely, because of different default encodings set. You can check it by running:

import sys
print sys.getdefaultencoding()

Also see:

I'm sure you've found your answer by now, but for those who are still looking for an answer:

When input-lg is used, margins mismatch unless you use form-group-lg in addition to form-group class. Its example is in docs:

<form class="form-horizontal">
  <div class="form-group form-group-lg">
    <label class="col-sm-2 control-label" for="formGroupInputLarge">Large label</label>
    <div class="col-sm-10">
      <input class="form-control" type="text" id="formGroupInputLarge" placeholder="Large input">
    </div>
  </div>
  <div class="form-group form-group-sm">
    <label class="col-sm-2 control-label" for="formGroupInputSmall">Small label</label>
    <div class="col-sm-10">
      <input class="form-control" type="text" id="formGroupInputSmall" placeholder="Small input">
    </div>
  </div>
</form>

I have got same issue on my server. Follow below steps -

1. Open command prompt (run as administrator)
2. type IISReset and enter.

It works and solved my problem.

The previous answers are correct but remember to use the name attribute in the input fields (html form) or you won't get anything. Example:

<input type="text" id="username" /> <!-- won't work --> <input type="text" name="username" /> <!-- will work --> <input type="text" name="username" id="username" /> <!-- will work too -->

All this code is HTML valid, but using getParameter(java.lang.String) you will need the name attribute been set in all parameters you want to receive.

For some reason @Alejandro Gracia answer starts working only after a few second. I found a solution that blocks the RecyclerView instantaneously:

recyclerView.addOnItemTouchListener(new RecyclerView.OnItemTouchListener() {
            @Override
            public boolean onInterceptTouchEvent(RecyclerView rv, MotionEvent e) {
                return true;
            }
            @Override
            public void onTouchEvent(RecyclerView rv, MotionEvent e) {
            }
            @Override
            public void onRequestDisallowInterceptTouchEvent(boolean disallowIntercept) {
            }
        });

I Created this module to help make this process piece of cake

You can do things like:

$routeProvider
  .state('secret',
    {
      ...
      permissions: {
        only: ['admin', 'god']
      }
    });

Or also

$routeProvider
  .state('userpanel',
    {
      ...
      permissions: {
        except: ['not-logged-in']
      }
    });

It's brand new but worth checking out!

Perhaps the project's type table is in an incorrect state. I would try to remove/add the reference and if that didn't work, create another project, import my code, and see if that works.

I ran into this while using VS 2005, one would expect MS to have fixed that particular problem by now though..

UPDATE: Added C# code, and link to Windows Jobs

I spent sometime trying to figure out this problem, and at the time XtremeVBTalk was the most active and responsive. Here is a link to my original post, Closing an Excel Interop process cleanly, even if your application crashes. Below is a summary of the post, and the code copied to this post.

• Closing the Interop process with Application.Quit() and Process.Kill() works for the most part, but fails if the applications crashes catastrophically. I.e. if the app crashes, the Excel process will still be running loose.
• The solution is to let the OS handle the cleanup of your processes through Windows Job Objects using Win32 calls. When your main application dies, the associated processes (i.e. Excel) will get terminated as well.

I found this to be a clean solution because the OS is doing real work of cleaning up. All you have to do is register the Excel process.

    Excel.Application app = new Excel.ApplicationClass();
    Job job = new Job();
    uint pid = 0;
    Win32.GetWindowThreadProcessId(new IntPtr(app.Hwnd), out pid);
    job.AddProcess(Process.GetProcessById((int)pid).Handle);

this some kind of late but anyway and it is also somewhat tricky

end if 
arr  = split(temp_var , "||") ' here you got new elemet in array ' 
for each x in arr
response.write(x & "<br />")

review and tell me if this can work or initially you save all data in string and later split for array

The link provided in the accepted answer shows a nice way to implement the pub/sub system using jQuery, but I found the code somewhat difficult to read, so here is my simplified version of the code:

http://jsfiddle.net/tFw89/5/

$(document).on('testEvent', function(e, eventInfo) { 
  subscribers = $('.subscribers-testEvent');
  subscribers.trigger('testEventHandler', [eventInfo]);
});

$('#myButton').on('click', function() {
  $(document).trigger('testEvent', [1011]);
});

$('#notifier1').on('testEventHandler', function(e, eventInfo) { 
  alert('(notifier1)The value of eventInfo is: ' + eventInfo);
});

$('#notifier2').on('testEventHandler', function(e, eventInfo) { 
  alert('(notifier2)The value of eventInfo is: ' + eventInfo);
});

$(this).find('.info').animate({'margin-top': '-50px', opacity: 0.5 }, 1000);

Not MarginTop. It works

You might want to do something like this (if you're in java 5 & up)

   tall[i++] = scanner.nextInt();

What do you mean by delete? In Python, removing a reference (or a name) can be done with the del keyword, but if there are other names to the same object that object will not be deleted.

--> test = 3
--> print(test)
3
--> del test
--> print(test)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
NameError: name 'test' is not defined

compared to:

--> test = 5
--> other is test  # check that both name refer to the exact same object
True
--> del test       # gets rid of test, but the object is still referenced by other
--> print(other)
5

c.AddFunc("0 30 * * * *", func() { fmt.Println("Every hour on the half hour") })
c.AddFunc("@hourly",      func() { fmt.Println("Every hour") })
c.AddFunc("@every 1h30m", func() { fmt.Println("Every hour thirty") })
c.Start()

Java 9 introduces

ifPresentOrElse if a value is present, performs the given action with the value, otherwise performs the given empty-based action.

See excellent Optional in Java 8 cheat sheet.

It provides all answers for most use cases.

Short summary below

ifPresent() - do something when Optional is set

opt.ifPresent(x -> print(x)); 
opt.ifPresent(this::print);

filter() - reject (filter out) certain Optional values.

opt.filter(x -> x.contains("ab")).ifPresent(this::print);

map() - transform value if present

opt.map(String::trim).filter(t -> t.length() > 1).ifPresent(this::print);

orElse()/orElseGet() - turning empty Optional to default T

int len = opt.map(String::length).orElse(-1);
int len = opt.
    map(String::length).
    orElseGet(() -> slowDefault());     //orElseGet(this::slowDefault)

orElseThrow() - lazily throw exceptions on empty Optional

opt.
filter(s -> !s.isEmpty()).
map(s -> s.charAt(0)).
orElseThrow(IllegalArgumentException::new);

If you want to call JavaScript function in C#, this will help you:

public string functionname(arg)
{
    if (condition)
    {
        Page page = HttpContext.Current.CurrentHandler as Page;
        page.ClientScript.RegisterStartupScript(
            typeof(Page),
            "Test",
            "<script type='text/javascript'>functionname1(" + arg1 + ",'" + arg2 + "');</script>");
    }
}

After adding php directory in User Settings,

{
    "php.validate.executablePath": "C:/phpdirectory/php7.1.8/php.exe",
    "php.executablePath": "C:/phpdirectory/php7.1.8/php.exe"
}

If you still have this error, please verify you have installed :

• 64-bit or 32-bit version of php (x64 or x86), depending on your OS;

• some librairies like Visual C++ Redistributable for Visual Studio 2015 : http://www.microsoft.com/en-us/download/details.aspx?id=48145;

To test if you PHP exe is ok, open cmd.exe :

c:/prog/php-7.1.8-Win32-VC14-x64/php.exe --version

If PHP fails, a message will be prompted with the error (missing dll for example).

Generally when I want to create a JSON or YAML string, I start out by building the Perl data structure, and then running a simple conversion on it. You could put a UI in front of the Perl data structure generation, e.g. a web form.

Converting a structure to JSON is very straightforward:

use strict;
use warnings;
use JSON::Any;

my $data = { arbitrary structure in here };
my $json_handler = JSON::Any->new(utf8=>1);
my $json_string = $json_handler->objToJson($data);

I have worked extensively in Excel and have found the following 3 points very useful

Find if there are cells which apparently do not hold any data but Excel considers them to have data

You can find this by using the following property on a sheet

ActiveSheet.UsedRange.Rows.Count
ActiveSheet.UsedRange.Columns.Count

If this range is more than the cells on which you have data, delete the rest of the rows/columns

You will be surprised to see the amount of space it can free

Convert files to .xlsb format

XLSM format is to make Excel compliant with Open XML, but there are very few instances when we actually use the XML format of Excel. This reduces size by almost 50% if not more

Optimum way of storing information

For example if you have to save the stock price for around 10 years, and you need to save Open, High, Low, Close for a stock, this would result in (252*10) * (4) cells being used

Instead, of using separate columns for Open,High,Low,Close save them in a single column with a field separator Open:High:Low:Close

You can easily write a function to extract info from the single column whenever you want to, but it will free up almost 2/3rd space that you are currently taking up

You can also use the following syntax for the strongly typed version:

<% using (Html.BeginForm<SomeController>(x=> x.SomeAction(), 
          FormMethod.Post, 
          new { enctype = "multipart/form-data" })) 
   { %>

If you want or need to work with a Java array then you can always use the java.util.Arrays utility classes' static asList() method to convert your array to a List.

Something along those lines should work.

String mStringArray[] = { "String1", "String2" };

JSONArray mJSONArray = new JSONArray(Arrays.asList(mStringArray));

Beware that code is written offhand so consider it pseudo-code.

for just minutes and seconds use this

String.format("%02d:%02d", (seconds / 3600 * 60 + ((seconds % 3600) / 60)), (seconds % 60))

This is the way to disable foreign key checks in MySQL. Not relevant to OP's question since they use MS SQL Server, but google search results do turn this up so here's for reference:

SET FOREIGN_KEY_CHECKS = 0;

/ Run your script /

SET FOREIGN_KEY_CHECKS = 1;

See if this helps, This is for ignoring the foreign key checks. But deleting disabling this is very bad practice.

ID tag - used by CSS, define a unique instance of a div, span or other elements. Appears within the Javascript DOM model, allowing you to access them with various function calls.

Name tag for fields - This is unique per form -- unless you are doing an array which you want to pass to PHP/server-side processing. You can access it via Javascript by name, but I think that it does not appear as a node in the DOM or some restrictions may apply (you cannot use .innerHTML, for example, if I recall correctly).

For my Raspberry Pi 3B model it was

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet manual

allow-hotplug wlan0
iface wlan0 inet manual
    wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

allow-hotplug wlan1
iface wlan1 inet manual
    wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

On Fedora 17 I had to install libjpeg-devel and afterwards reinstall PIL:

sudo yum install --assumeyes libjpeg-devel
sudo pip-python install --upgrade PIL

On (mostly) old processors, multiplying by 31 can be relatively cheap. On an ARM, for instance, it is only one instruction:

RSB       r1, r0, r0, ASL #5    ; r1 := - r0 + (r0<<5)

Most other processors would require a separate shift and subtract instruction. However, if your multiplier is slow this is still a win. Modern processors tend to have fast multipliers so it doesn't make much difference, so long as 32 goes on the correct side.

It's not a great hash algorithm, but it's good enough and better than the 1.0 code (and very much better than the 1.0 spec!).

realy simple

"9001234567".match(/^\d{10}$/g)

Just use break, like that:

int cont = 0;
foreach (ListViewItem lvi in listView.Items) {
   if(cont==50) { //if listViewItem reach 50 break out.
      break; 
   }
   cont++;   //increment cont.
}

#include<stdio.h>
int b=1;
int printS(){    
    printf("%d\n",b);
    b++;
    (1001-b) && printS();
}
int main(){printS();}

I got same problem lot of time. Check your request url, if you are requesting on local server like 127.1.1/api or 192.168...., try to change it, make sure you are hitting cloud.

If you put together the answers so far, clean up and improve, you would arrive at this superior query:

UPDATE sales
SET    status = 'ACTIVE'
WHERE  (saleprice, saledate) IN (
    SELECT saleprice, saledate
    FROM   sales
    GROUP  BY saleprice, saledate
    HAVING count(*) = 1 
    );

Which is much faster than either of them. Nukes the performance of the currently accepted answer by factor 10 - 15 (in my tests on PostgreSQL 8.4 and 9.1).

But this is still far from optimal. Use a NOT EXISTS (anti-)semi-join for even better performance. EXISTS is standard SQL, has been around forever (at least since PostgreSQL 7.2, long before this question was asked) and fits the presented requirements perfectly:

UPDATE sales s
SET    status = 'ACTIVE'
WHERE  NOT EXISTS (
   SELECT FROM sales s1                     -- SELECT list can be empty for EXISTS
   WHERE  s.saleprice = s1.saleprice
   AND    s.saledate  = s1.saledate
   AND    s.id <> s1.id                     -- except for row itself
   )
AND    s.status IS DISTINCT FROM 'ACTIVE';  -- avoid empty updates. see below

db<>fiddle here
Old SQL Fiddle

Unique key to identify row

If you don't have a primary or unique key for the table (id in the example), you can substitute with the system column ctid for the purpose of this query (but not for some other purposes):

   AND    s1.ctid <> s.ctid

_{Every table should have a primary key. Add one if you didn't have one, yet. I suggest a serial or an IDENTITY column in Postgres 10+.}

Related:

• In-order sequence generation
• Auto increment table column

How is this faster?

The subquery in the EXISTS anti-semi-join can stop evaluating as soon as the first dupe is found (no point in looking further). For a base table with few duplicates this is only mildly more efficient. With lots of duplicates this becomes way more efficient.

Exclude empty updates

For rows that already have status = 'ACTIVE' this update would not change anything, but still insert a new row version at full cost (minor exceptions apply). Normally, you do not want this. Add another WHERE condition like demonstrated above to avoid this and make it even faster:

If status is defined NOT NULL, you can simplify to:

AND status <> 'ACTIVE';

The data type of the column must support the <> operator. Some types like json don't. See:

• How to query a json column for empty objects?

Subtle difference in NULL handling

This query (unlike the currently accepted answer by Joel) does not treat NULL values as equal. The following two rows for (saleprice, saledate) would qualify as "distinct" (though looking identical to the human eye):

(123, NULL)
(123, NULL)

Also passes in a unique index and almost anywhere else, since NULL values do not compare equal according to the SQL standard. See:

• Create unique constraint with null columns

OTOH, GROUP BY, DISTINCT or DISTINCT ON () treat NULL values as equal. Use an appropriate query style depending on what you want to achieve. You can still use this faster query with IS NOT DISTINCT FROM instead of = for any or all comparisons to make NULL compare equal. More:

• How to delete duplicate rows without unique identifier

If all columns being compared are defined NOT NULL, there is no room for disagreement.

it solved me by adjusting code from @Connor Cushion Mulhall by

iframe, object, embed {_x000D_
  width: 100%;_x000D_
  display: block !important;_x000D_
}

By using sscanf we can convert string to float.

#include<stdio.h>    
#include<string.h>    

int main() 
{
    char str[100] ="4.0800" ;     
    const char s[2] = "-";   
    char *token;
    double x;
   /* get the first token */ 
   token = strtok(str, s);
   sscanf(token,"%f",&x);
    printf( " %f",x );

    return 0; 
}

I agree with William that in general it is a bad idea to hijack the function keys. That said, I found the shortcut library that adds this functionality, as well as other keyboard shortcuts and combination, in a very slick way.

Single keystroke:

shortcut.add("F1", function() {
    alert("F1 pressed");
});

Combination of keystrokes:

shortcut.add("Ctrl+Shift+A", function() {
    alert("Ctrl Shift A pressed");
});

First off, you shouldn't add $ when you're outside of strings ($class in your first function being an exception), so it should be:

def doCopyMibArtefactsHere(projectName) {
    step ([
        $class: 'CopyArtifact',
        projectName: projectName,
        filter: '**/**.mib',
        fingerprintArtifacts: true, 
        flatten: true
    ]);
}

def BuildAndCopyMibsHere(projectName, params) {
    build job: project, parameters: params
    doCopyMibArtefactsHere(projectName)
}
...

Now, as for your problem; the second function takes two arguments while you're only supplying one argument at the call. Either you have to supply two arguments at the call:

...
node { 
    stage('Prepare Mib'){
        BuildAndCopyMibsHere('project1', null)
    }
}

... or you need to add a default value to the functions' second argument:

def BuildAndCopyMibsHere(projectName, params = null) {
    build job: project, parameters: params
    doCopyMibArtefactsHere($projectName)
}

Like the others said:

inputString.split('\n')  # --> ['Line 1', 'Line 2', 'Line 3']

This is identical to the above, but the string module's functions are deprecated and should be avoided:

import string
string.split(inputString, '\n')  # --> ['Line 1', 'Line 2', 'Line 3']

Alternatively, if you want each line to include the break sequence (CR,LF,CRLF), use the splitlines method with a True argument:

inputString.splitlines(True)  # --> ['Line 1\n', 'Line 2\n', 'Line 3']

Use sysdate-1 to subtract one day from system date.

select sysdate, sysdate -1 from dual;

Output:

SYSDATE  SYSDATE-1
-------- ---------
22-10-13 21-10-13 

To be honest, I didn't like any of previous the solutions.

The best way to do this, is binding the "click" event to the document, and comparing if that click is really outside the element (just like Art said in his suggestion).

However, you'll have some problems there: You'll never be able to unbind it, and you cannot have an external button to open/close that element.

That's why I wrote this small plugin (click here to link), to simplify these tasks. Could it be simpler?

<a id='theButton' href="#">Toggle the menu</a><br/>
<div id='theMenu'>
    I should be toggled when the above menu is clicked,
    and hidden when user clicks outside.
</div>

<script>
$('#theButton').click(function(){
    $('#theMenu').slideDown();
});
$("#theMenu").dClickOutside({ ignoreList: $("#theButton") }, function(clickedObj){
    $(this).slideUp();
});
</script>

The best approach for this sort of thing is probably git rebase. It allows you to pull changes from master into your development branch, but leave all of your development work "on top of" (later in the commit log) the stuff from master. When your new work is complete, the merge back to master is then very straightforward.

You don't need EXEC clause. Simply use

proc_name paramValue1, paramValue2

(and you need commas as Misnomer mentioned)

The wb indicates that the file is opened for writing in binary mode.

When writing in binary mode, Python makes no changes to data as it is written to the file. In text mode (when the b is excluded as in just w or when you specify text mode with wt), however, Python will encode the text based on the default text encoding. Additionally, Python will convert line endings (\n) to whatever the platform-specific line ending is, which would corrupt a binary file like an exe or png file.

Text mode should therefore be used when writing text files (whether using plain text or a text-based format like CSV), while binary mode must be used when writing non-text files like images.

From the PHP Manual:

Warning This extension was deprecated in PHP 5.5.0, and it was removed in PHP 7.0.0. Instead, the MySQLi or PDO_MySQL extension should be used. See also MySQL: choosing an API guide. Alternatives to this function include:

mysqli_connect()

PDO::__construct()

use MySQLi or PDO

<?php
$con = mysqli_connect('localhost', 'username', 'password', 'database');

What are you using to compile this? If there's an undefined reference error, usually it's because the .o file (which gets created from the .cpp file) doesn't exist and your compiler/build system is not able to link it.

Also, in your card.cpp, the function should be Card::Card() instead of void Card. The Card:: is scoping; it means that your Card() function is a member of the Card class (which it obviously is, since it's the constructor for that class). Without this, void Card is just a free function. Similarly,

void Card(Card::Rank rank, Card::Suit suit)

should be

Card::Card(Card::Rank rank, Card::Suit suit)

Also, in deck.cpp, you are saying #include "Deck.h" even though you referred to it as deck.h. The includes are case sensitive.

The each function iterates over an array, calling the supplied function once per element, and setting this to the active element. This:

function countdown() {
    alert(this + "..");
}

$([5, 4, 3, 2, 1]).each(countdown);

will alert 5.. then 4.. then 3.. then 2.. then 1..

Map on the other hand takes an array, and returns a new array with each element changed by the function. This:

function squared() {
    return this * this;
}

var s = $([5, 4, 3, 2, 1]).map(squared);

would result in s being [25, 16, 9, 4, 1].

Using location.go(url) is the way to go, but instead of hardcoding the url , consider generating it using router.createUrlTree().

Given that you want to do the following router call: this.router.navigate([{param: 1}], {relativeTo: this.activatedRoute}) but without reloading the component, it can be rewritten as:

const url = this.router.createUrlTree([], {relativeTo: this.activatedRoute, queryParams: {param: 1}}).toString()

 this.location.go(url);

Is this what you are looking for:

myListBox.DataSource = MyList;

CSS

:active denotes the interaction state (so for a button will be applied during press), :focus may be a better choice here. However, the styling will be lost once another element gains focus.

The final potential alternative using CSS would be to use :target, assuming the items being clicked are setting routes (e.g. anchors) within the page- however this can be interrupted if you are using routing (e.g. Angular), however this doesnt seem the case here.

.active:active {_x000D_
  color: red;_x000D_
}_x000D_
.focus:focus {_x000D_
  color: red;_x000D_
}_x000D_
:target {_x000D_
  color: red;_x000D_
}

<button class='active'>Active</button>_x000D_
<button class='focus'>Focus</button>_x000D_
<a href='#target1' id='target1' class='target'>Target 1</a>_x000D_
<a href='#target2' id='target2' class='target'>Target 2</a>_x000D_
<a href='#target3' id='target3' class='target'>Target 3</a>

Javascript / jQuery

As such, there is no way in CSS to absolutely toggle a styled state- if none of the above work for you, you will either need to combine with a change in your HTML (e.g. based on a checkbox) or programatically apply/remove a class using e.g. jQuery

$('button').on('click', function(){_x000D_
    $('button').removeClass('selected');_x000D_
    $(this).addClass('selected');_x000D_
});

button.selected{_x000D_
  color:red;_x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
_x000D_
<button>Item</button><button>Item</button><button>Item</button>_x000D_
  

Change your second table code like below.

<table style="border: 1px solid red;width:300px;display:block;">
<thead>
    <tr>
        <td width=150>Name</td>
        <td width=150>phone</td>
    </tr>
</thead>
<tbody style='height:50px;overflow:auto;display:block;width:317px;'>
    <tr>
        <td width=150>AAAA</td>
        <td width=150>323232</td>
    </tr>
    <tr>
        <td>BBBBB</td>
        <td>323232</td>
    </tr>
    <tr>
        <td>CCCCC</td>
        <td>3435656</td>
    </tr>
</tbody>
</table>

JSFIDDLE DEMO

Your fundamental problem is that grep works one line at a time - so it cannot find a SELECT statement spread across lines.

Your second problem is that the regex you are using doesn't deal with the complexity of what can appear between SELECT and FROM - in particular, it omits commas, full stops (periods) and blanks, but also quotes and anything that can be inside a quoted string.

I would likely go with a Perl-based solution, having Perl read 'paragraphs' at a time and applying a regex to that. The downside is having to deal with the recursive search - there are modules to do that, of course, including the core module File::Find.

In outline, for a single file:

$/ = "\n\n";    # Paragraphs

while (<>)
{
     if ($_ =~ m/SELECT.*customerName.*FROM/mi)
     {
         printf file name
         go to next file
     }
}

That needs to be wrapped into a sub that is then invoked by the methods of File::Find.

After much pain and suffering, turns out I needed to install the "Visual C++ Redistributable for Visual Studio 2012 Update 4 32-bit version", even on my 64-bit server.

The difference is that if you only specify the DOCTYPE, IE’s Compatibility View Settings take precedence. By default these settings force all intranet sites into Compatibility View regardless of DOCTYPE. There’s also a checkbox to use Compatibility View for all websites, regardless of DOCTYPE.

X-UA-Compatible overrides the Compatibility View Settings, so the page will render in standards mode regardless of the browser settings. This forces standards mode for:

• intranet pages
• external web pages when the computer administrator has chosen “Display all websites in Compatibility View” as the default—think big companies, governments, universities
• when you unintentionally end up on the Microsoft Compatibility View List
• cases where users have manually added your website to the list in Compatibility View Settings

DOCTYPE alone cannot do that; you will end up in one of the Compatibility View modes in these cases regardless of DOCTYPE.

If both the meta tag and the HTTP header are specified, the meta tag takes precedence.

This answer is based on examining the complete rules for deciding document mode in IE8, IE9, and IE10. Note that looking at the DOCTYPE is the very last fallback for deciding the document mode.

I came across to this post but I wanted to sort by time when returning the items inside my class and I got an error.

So I research the php.net website and end up doing this:

class MyClass {
   public function getItems(){
      usort( $this->items, array("MyClass", "sortByTime") );
      return $this->items;
   }
   public function sortByTime($a, $b){
      return $b["time"] - $a["time"];
   }
}

You can find very useful examples in the PHP.net website

My array looked like this:

  'recent' => 
    array
      92 => 
        array
          'id' => string '92' (length=2)
          'quantity' => string '1' (length=1)
          'time' => string '1396514041' (length=10)
      52 => 
        array
          'id' => string '52' (length=2)
          'quantity' => string '8' (length=1)
          'time' => string '1396514838' (length=10)
      22 => 
        array
          'id' => string '22' (length=2)
          'quantity' => string '1' (length=1)
          'time' => string '1396514871' (length=10)
      81 => 
        array
          'id' => string '81' (length=2)
          'quantity' => string '2' (length=1)
          'time' => string '1396514988' (length=10)

I used a temp table and finally got this to work. Here is the logic that is used once you create the temp table:

UPDATE your_table, temp
SET your_table.value = temp.value
WHERE your_table.id = temp.id

I had to find the same answer. The best example I found is http://www.cssplay.co.uk/menu/tablescroll.html - I found example #2 worked well for me. You will have to set the height of the inner table with Java Script, the rest is CSS.

There is an open bug on Chromium: https://bugs.chromium.org/p/chromium/issues/detail?id=584905

Unfortunately they depend on Apple to open up an API in WKView for this to happen, after which maybe debugging will be available from Safari.

In some cases, you may run into a problem of synchronization with this method. I wrote the callback call inside a setTimeout function, and it worked synchronously just fine =)

E.G:

function obterJson(callback) {


    jqxhr = $.getJSON(window.location.href + "js/data.json", function(data) {

    setTimeout(function(){
        callback(data);
    },0);
}

I tried the other solutions here, they work but I'm lazy so this is my solution

1. hover over the element to trigger expanded state
2. ctrl+shift+c
3. hover over element again
4. right click
5. navigate to the debugger

by right clicking it no longer registers mouse event since a context menu pops up, so you can move the mouse away safely

Instead of doing this via an SQL query use the php function: mysqli::set_charset mysqli_set_charset

Note:

This is the preferred way to change the charset. Using mysqli_query() to set it (such as SET NAMES utf8) is not recommended.

See the MySQL character set concepts section for more information.

from http://www.php.net/manual/en/mysqli.set-charset.php

This code might work:

//if the directory exists
 DWORD dwAttr = GetFileAttributes(str);
 if(dwAttr != 0xffffffff && (dwAttr & FILE_ATTRIBUTE_DIRECTORY)) 

def inside():
   global var
   var = 'info'
inside()
print(var)

>>>'info'

problem ended

additional desc params for Ege Özcan code

function dynamicSort(property, desc) {
    if (desc) {
        return function (a, b) {
            return (a[property] > b[property]) ? -1 : (a[property] < b[property]) ? 1 : 0;
        }   
    }
    return function (a, b) {
        return (a[property] < b[property]) ? -1 : (a[property] > b[property]) ? 1 : 0;
    }
}

Just do myFunction.foo = "bar" and it will add it. myFunction is the name of the object in this case.

You need to include the path of the libraries inside /etc/ld.so.conf, and rerun ldconfig to upate the list

Other possibility is to include in the env variable LD_LIBRARY_PATH the path to your library, and rerun the executable.

check the symbolic links if they point to a valid library ...

You can add the path directly in /etc/ld.so.conf, without include...

run ldconfig -p to see whether your library is well included in the cache.

//an easy way:
str := fmt.Sprint(data)

In order to achieve what you want, you need to use jQuery Ajax as below:

$('#myForm').submit(function(e){
    e.preventDefault();
    $.ajax({
        url: '/Car/Edit/17/',
        type: 'post',
        data:$('#myForm').serialize(),
        success:function(){
            // Whatever you want to do after the form is successfully submitted
        }
    });
});

Also try this one:

function SubForm(e){
    e.preventDefault();
    var url = $(this).closest('form').attr('action'),
    data = $(this).closest('form').serialize();
    $.ajax({
        url: url,
        type: 'post',
        data: data,
        success: function(){
           // Whatever you want to do after the form is successfully submitted
       }
   });
}

Final solution

This worked flawlessly. I call this function from Html.ActionLink(...)

function SubForm (){
    $.ajax({
        url: '/Person/Edit/@Model.Id/',
        type: 'post',
        data: $('#myForm').serialize(),
        success: function(){
            alert("worked");
        }
    });
}

All above will works fine. But the right method is this:

yourString = [yourString stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceCharacterSet]];

It will work like a TRIM method. It will remove all front and back spaces.

Thanks

You're correct. As others said according to your comments, you probably did not initialize your ArrayList.

My point is different: you claimed that you're checking for duplicates and this is why you call the contains method. Try using HashSet. It should be more efficient - unless you need to keep the order of URLs for any reason.

I had a similar issue and ended up with this:

For me this has the advantage that data and annotation are not overlapping.

from matplotlib import pyplot as plt
import numpy as np

fig = plt.figure()
ax = fig.add_subplot(111)

A = -0.75, -0.25, 0, 0.25, 0.5, 0.75, 1.0
B = 0.73, 0.97, 1.0, 0.97, 0.88, 0.73, 0.54

plt.plot(A,B)

# annotations at the side (ordered by B values)
x0,x1=ax.get_xlim()
y0,y1=ax.get_ylim()
for ii, ind in enumerate(np.argsort(B)):
    x = A[ind]
    y = B[ind]
    xPos = x1 + .02 * (x1 - x0)
    yPos = y0 + ii * (y1 - y0)/(len(B) - 1)
    ax.annotate('',#label,
          xy=(x, y), xycoords='data',
          xytext=(xPos, yPos), textcoords='data',
          arrowprops=dict(
                          connectionstyle="arc3,rad=0.",
                          shrinkA=0, shrinkB=10,
                          arrowstyle= '-|>', ls= '-', linewidth=2
                          ),
          va='bottom', ha='left', zorder=19
          )
    ax.text(xPos + .01 * (x1 - x0), yPos,
            '({:.2f}, {:.2f})'.format(x,y),
            transform=ax.transData, va='center')

plt.grid()
plt.show()

Using the text argument in .annotate ended up with unfavorable text positions. Drawing lines between a legend and the data points is a mess, as the location of the legend is hard to address.

You could decorate your view model property with the [DisplayName] attribute and specify the text to be used:

[DisplayName("foo bar")]
public string SomekingStatus { get; set; }

Or use another overload of the LabelFor helper which allows you to specify the text:

@Html.LabelFor(model => model.SomekingStatus, "foo bar")

And, no, you cannot specify a class name in MVC3 as you tried to do, as the LabelFor helper doesn't support that. However, this would work in MVC4 or 5.

00 23 * * * [[ $(date +'%d') -eq $(cal | awk '!/^$/{ print $NF }' | tail -1) ]] && job

Check out a related question on the unix.com forum.

If you're using JSX with Harmony, you could do this:

<img className="image" src={`images/${this.props.image}`} />

Here you are writing the value of src as an expression.

The best solution seem to be to create a file list and then archive files because you can use other sources and do something else with the list.

For example this allows using the list to calculate size of the files being archived:

#!/bin/sh

backupFileName="backup-big-$(date +"%Y%m%d-%H%M")"
backupRoot="/var/www"
backupOutPath=""

archivePath=$backupOutPath$backupFileName.tar.gz
listOfFilesPath=$backupOutPath$backupFileName.filelist

#
# Make a list of files/directories to archive
#
echo "" > $listOfFilesPath
echo "${backupRoot}/uploads" >> $listOfFilesPath
echo "${backupRoot}/extra/user/data" >> $listOfFilesPath
find "${backupRoot}/drupal_root/sites/" -name "files" -type d >> $listOfFilesPath

#
# Size calculation
#
sizeForProgress=`
cat $listOfFilesPath | while read nextFile;do
    if [ ! -z "$nextFile" ]; then
        du -sb "$nextFile"
    fi
done | awk '{size+=$1} END {print size}'
`

#
# Archive with progress
#
## simple with dump of all files currently archived
#tar -czvf $archivePath -T $listOfFilesPath
## progress bar
sizeForShow=$(($sizeForProgress/1024/1024))
echo -e "\nRunning backup [source files are $sizeForShow MiB]\n"
tar -cPp -T $listOfFilesPath | pv -s $sizeForProgress | gzip > $archivePath

Most of the given solutions using the mouseup or contextmenu events fire every time the right mouse button goes up, but they don't check wether it was down before.

If you are looking for a true right click event, which only fires when the mouse button has been pressed and released within the same element, then you should use the auxclick event. Since this fires for every none-primary mouse button you should also filter other events by checking the button property.

window.addEventListener("auxclick", (event) => {
  if (event.button === 2) alert("Right click");
});

You can also create your own right click event by adding the following code to the start of your JavaScript:

{
  const rightClickEvent = new CustomEvent('rightclick', { bubbles: true });
  window.addEventListener("auxclick", (event) => {
    if (event.button === 2) {
      event.target.dispatchEvent(rightClickEvent);
    }
  });
}

You can then listen for right click events via the addEventListener method like so:

your_element.addEventListener("rightclick", your_function);

Read more about the auxclick event on MDN.

What you have is correct, though you will not call it global, it is a class attribute and can be accessed via class e.g Shape.lolwut or via an instance e.g. shape.lolwut but be careful while setting it as it will set an instance level attribute not class attribute

class Shape(object):
    lolwut = 1

shape = Shape()

print Shape.lolwut,  # 1
print shape.lolwut,  # 1

# setting shape.lolwut would not change class attribute lolwut 
# but will create it in the instance
shape.lolwut = 2

print Shape.lolwut,  # 1
print shape.lolwut,  # 2

# to change class attribute access it via class
Shape.lolwut = 3

print Shape.lolwut,  # 3
print shape.lolwut   # 2 

output:

1 1 1 2 3 2

Somebody may expect output to be 1 1 2 2 3 3 but it would be incorrect

I just encountered this problem. I tried a few things, but settled on using JSoup. The jar is about 132k, which is a bit big, but if you download the source and take out some of the methods you will not be using, then it is not as big.
=> Good thing about it is that it will handle badly formed HTML

Here's a good example from their site.

File input = new File("/tmp/input.html");
Document doc = Jsoup.parse(input, "UTF-8", "http://example.com/");

//http://jsoup.org/cookbook/input/load-document-from-url
//Document doc = Jsoup.connect("http://example.com/").get();

Element content = doc.getElementById("content");
Elements links = content.getElementsByTag("a");
for (Element link : links) {
  String linkHref = link.attr("href");
  String linkText = link.text();
}

I just ran into the exact same problem (same Python version, OS, code, etc).

You just have to copy Python's Lib/ directory in your program's working directory ( on VC it's the directory where the .vcproj is )

All these answers around here, as well as the answers in this question, suggest that loading absolute URLs, like "/foo/bar.properties" treated the same by class.getResourceAsStream(String) and class.getClassLoader().getResourceAsStream(String). This is NOT the case, at least not in my Tomcat configuration/version (currently 7.0.40).

MyClass.class.getResourceAsStream("/foo/bar.properties"); // works!  
MyClass.class.getClassLoader().getResourceAsStream("/foo/bar.properties"); // does NOT work!

Sorry, I have absolutely no satisfying explanation, but I guess that tomcat does dirty tricks and his black magic with the classloaders and cause the difference. I always used class.getResourceAsStream(String) in the past and haven't had any problems.

PS: I also posted this over here

Docker:

I was getting this problem from my Dockerfile as I had:

RUN bash < <(curl -s -S -L https://raw.githubusercontent.com/moovweb/gvm/master/binscripts/gvm-installer)

However, according to this issue, it was solved:

The exec form makes it possible to avoid shell string munging, and to RUN commands using a base image that does not contain /bin/sh.

Note

To use a different shell, other than /bin/sh, use the exec form passing in the desired shell. For example,

RUN ["/bin/bash", "-c", "echo hello"]

Solution:

RUN ["/bin/bash", "-c", "bash < <(curl -s -S -L https://raw.githubusercontent.com/moovweb/gvm/master/binscripts/gvm-installer)"]

Notice the quotes around each parameter.

I changed @Eli Bendersky's answer a little bit to use the ctor __init__() and dtor __del__() to do the timing, so that it can be used more conveniently without indenting the original code:

class Timer(object):
    def __init__(self, name=None):
        self.name = name
        self.tstart = time.time()

    def __del__(self):
        if self.name:
            print '%s elapsed: %.2fs' % (self.name, time.time() - self.tstart)
        else:
            print 'Elapsed: %.2fs' % (time.time() - self.tstart)

To use, simple put Timer("blahblah") at the beginning of some local scope. Elapsed time will be printed at the end of the scope:

for i in xrange(5):
    timer = Timer("eigh()")
    x = numpy.random.random((4000,4000));
    x = (x+x.T)/2
    numpy.linalg.eigh(x)
    print i+1
timer = None

It prints out:

1
eigh() elapsed: 10.13s
2
eigh() elapsed: 9.74s
3
eigh() elapsed: 10.70s
4
eigh() elapsed: 10.25s
5
eigh() elapsed: 11.28s

Swift 3 Update

Replace

Selector("tapFunction:")

with

#selector(DetailViewController.tapFunction)

Example:

class DetailViewController: UIViewController {

    @IBOutlet weak var tripDetails: UILabel!

    override func viewDidLoad() {
        super.viewDidLoad()
        ...

        let tap = UITapGestureRecognizer(target: self, action: #selector(DetailViewController.tapFunction))
        tripDetails.isUserInteractionEnabled = true
        tripDetails.addGestureRecognizer(tap)
    }

    @objc
    func tapFunction(sender:UITapGestureRecognizer) {
        print("tap working")
    }
}

You might need a bit more background on what a Materialized View actually is. In Oracle these are an object that consists of a number of elements when you try to build it elsewhere.

An MVIEW is essentially a snapshot of data from another source. Unlike a view the data is not found when you query the view it is stored locally in a form of table. The MVIEW is refreshed using a background procedure that kicks off at regular intervals or when the source data changes. Oracle allows for full or partial refreshes.

In SQL Server, I would use the following to create a basic MVIEW to (complete) refresh regularly.

First, a view. This should be easy for most since views are quite common in any database Next, a table. This should be identical to the view in columns and data. This will store a snapshot of the view data. Then, a procedure that truncates the table, and reloads it based on the current data in the view. Finally, a job that triggers the procedure to start it's work.

Everything else is experimentation.

I have created a responsive sample that works well for me and I find it to be quite simple have a look at my carousel-fill:

.carousel-fill {
    height: -o-calc(100vh - 165px) !important;
    height: -webkit-calc(100vh - 165px) !important;
    height: -moz-calc(100vh - 165px) !important;
    height: calc(100vh - 165px) !important;
    width: auto !important;
    overflow: hidden;
    display: inline-block;
    text-align: center;
}

.carousel-item {
    text-align: center !important;
}

my navigation height+footer are a hair less then 165px so that value works for me. take off a value that fits for you, I overrdide the .carousel-item from bootstrap so make sure by videos are centered.

my carousel looks like this, note the "carousel-fill" on the video tag.

<div>
        <div id="myCarousel" class="carousel slide carousel-fade text-center" data-ride="carousel">

in case some one needs to control the videos like i do, I start and stop the videos like this:

            $('.carousel').carousel({ interval: 8000 })
            $('#myCarousel').on('slide.bs.carousel', function (args) {
                var videoList = document.getElementsByTagName("video");
                switch (args.from) {
                    case 0:
                        videoList[0].pause();
                        break;
                    case 1:
                        videoList[1].pause();
                        break;
                    case 2:
                        videoList[2].pause();
                        break;
                }
                switch (args.to) {
                    case 0:
                        videoList[0].play();

                        break;
                    case 1:
                        videoList[1].play();
                        break;
                    case 2:
                        videoList[2].play();
                        break;
                }
            })

        });

Adding on to Carlos Calla's great answer.

The height of .modal-body must be set, BUT you can use media queries to make sure it's appropriate for the screen size.

.modal-body{
    height: 250px;
    overflow-y: auto;
}

@media (min-height: 500px) {
    .modal-body { height: 400px; }
}

@media (min-height: 800px) {
    .modal-body { height: 600px; }
}

In newer versions of Notepad++ (currently 5.9), this option is under:

View->Show Symbol->Show All Characters

or

View->Show Symbol->Show White Space and Tab

Exception for DialogFragment though, focus of the embedded Dialog must be hidden, instead only the first EditText within the embedded Dialog

this.getDialog().getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_HIDDEN);

As other mentioned JSX is not a standard Javascript extension. It's better to name your entry point of Application based on .js and for the rest components, you can use .jsx.

I have an important reason for why I'm using .JSX for all component's file names. Actually, In a large scale project with huge bunch of code, if we set all React's component with .jsx extension, It'll be easier while navigating to different javascript files across the project(like helpers, middleware, etc.) and you know this is a React Component and not other types of the javascript file.

You won't see a simple answer because there isn't one.

First, Unicode doesn't contain "every character from every language", although it sure does try.

Unicode itself is a mapping, it defines codepoints and a codepoint is a number, associated with usually a character. I say usually because there are concepts like combining characters. You may be familiar with things like accents, or umlauts. Those can be used with another character, such as an a or a u to create a new logical character. A character therefore can consist of 1 or more codepoints.

To be useful in computing systems we need to choose a representation for this information. Those are the various unicode encodings, such as utf-8, utf-16le, utf-32 etc. They are distinguished largely by the size of of their codeunits. UTF-32 is the simplest encoding, it has a codeunit that is 32bits, which means an individual codepoint fits comfortably into a codeunit. The other encodings will have situations where a codepoint will need multiple codeunits, or that particular codepoint can't be represented in the encoding at all (this is a problem for instance with UCS-2).

Because of the flexibility of combining characters, even within a given encoding the number of bytes per character can vary depending on the character and the normalization form. This is a protocol for dealing with characters which have more than one representation (you can say "an 'a' with an accent" which is 2 codepoints, one of which is a combining char or "accented 'a'" which is one codepoint).

You can parse the date using the Date constructor, then spit out the individual time components:

function convert(str) {_x000D_
  var date = new Date(str),_x000D_
    mnth = ("0" + (date.getMonth() + 1)).slice(-2),_x000D_
    day = ("0" + date.getDate()).slice(-2);_x000D_

As you can see from the result though, this will parse the date into the local time zone. If you want to keep the date based on the original time zone, the easiest approach is to split the string and extract the parts you need:

function convert(str) {_x000D_
  var mnths = {_x000D_
      Jan: "01",_x000D_
      Feb: "02",_x000D_

# start with the mtcars data frame (included with your installation of R)
mtcars

# pick your 'group by' variable

I would simply look for a $_GET variable and redirect the user if it's not correct.

<?php
$pass = $_GET['pass'];
if($pass != 'my-secret-password') {
  header('Location: http://www.staggeringbeauty.com/');
}
?>

Now, if this page is located at say: http://example.com/secrets/files.php

You can now access it with: http://example.com/secrets/files.php?pass=my-secret-password Keep in mind that this isn't the most efficient or secure way, but nonetheless it is a easy and fast way. (Also, I know my answer is outdated but someone else looking at this question may find it valuable)

In MAC OS Catalina, this are the steps that worked for me, all the above solutions did help but didn't solve my problem.

1. check node --version, still the old one in use.
2. cd ~/
3. atom .bash_profile
4. Remove the $PATH pointing to old node version, in my case it was /usr/local/bin/node/@node8
5. Add & save this to $PATH instead "export PATH=$PATH:/usr/local/git/bin:/usr/local/bin"
6. Close all applications using node (terminal, simulator, browser expo etc)
7. restart terminal and check node --version

1. Open the file using vi myfile.csv
2. Press Escape
3. Type :%s/replaceme/withthis/
4. Type :wq and press Enter

Now you will have the new pattern in your file.

If you want it to check explicit for it to not be false (boolean value) you have to use

if(borrar() !== false)

But in JavaScript we usually use falsy and truthy and you could use

if(!borrar())

but then values 0, '', null, undefined, null and NaN would not generate the alert.

The following values are always falsy:

false,
,0 (zero)
,'' or "" (empty string)
,null
,undefined
,NaN

Everything else is truthy. That includes:

'0' (a string containing a single zero)
,'false' (a string containing the text “false”)
,[] (an empty array)
,{} (an empty object)
,function(){} (an “empty” function)

Source: https://www.sitepoint.com/javascript-truthy-falsy/

As an extra perk to convert any value to true or false (boolean type), use double exclamation mark:

!![] === true
!!'false' === true
!!false === false
!!undefined === false

You can find dimension of an image on the page using something like

document.getElementById('someImage').width

file size, however, you will have to use something server-side

import zipfile
with zipfile.ZipFile(path_to_zip_file, 'r') as zip_ref:
    zip_ref.extractall(directory_to_extract_to)

That's pretty much it!

Every time an entity is updated in the database the version field will be increased by one. Every operation that updates the entity in the database will have appended WHERE version = VERSION_THAT_WAS_LOADED_FROM_DATABASE to its query.

In checking affected rows of your operation the jpa framework can make sure there was no concurrent modification between loading and persisting your entity because the query would not find your entity in the database when it's version number has been increased between load and persist.

You can append to a csv by opening the file in append mode:

with open('my_csv.csv', 'a') as f:
    df.to_csv(f, header=False)

If this was your csv, foo.csv:

,A,B,C
0,1,2,3
1,4,5,6

If you read that and then append, for example, df + 6:

In [1]: df = pd.read_csv('foo.csv', index_col=0)

In [2]: df
Out[2]:
   A  B  C
0  1  2  3
1  4  5  6

In [3]: df + 6
Out[3]:
    A   B   C
0   7   8   9
1  10  11  12

In [4]: with open('foo.csv', 'a') as f:
             (df + 6).to_csv(f, header=False)

foo.csv becomes:

,A,B,C
0,1,2,3
1,4,5,6
0,7,8,9
1,10,11,12

I was over-complicating myself. After taking a long break and coming back, the desired output could be accomplished by this simple query:

SELECT Sandwiches.[Sandwich Type], Sandwich.Bread, Count(Sandwiches.[SandwichID]) AS [Total Sandwiches]
FROM Sandwiches
GROUP BY Sandwiches.[Sandwiches Type], Sandwiches.Bread;

Thanks for answering, it helped my train of thought.

The @ symbol denotes an annotation type definition.

That means it is not really an interface, but rather a new annotation type -- to be used as a function modifier, such as @override.

See this javadocs entry on the subject.

If you even did not get scroll after doing what is written above .....

Set the android:layout_height="250dp"or you can say xdp where x can be any numerical value.

If you want to access dict keys as an object (or as a dict for difficult keys), do it recursively, and also be able to update the original dict, you could do:

class Dictate(object):
    """Object view of a dict, updating the passed in dict when values are set
    or deleted. "Dictate" the contents of a dict...: """

    def __init__(self, d):
        # since __setattr__ is overridden, self.__dict = d doesn't work
        object.__setattr__(self, '_Dictate__dict', d)

    # Dictionary-like access / updates
    def __getitem__(self, name):
        value = self.__dict[name]
        if isinstance(value, dict):  # recursively view sub-dicts as objects
            value = Dictate(value)
        return value

    def __setitem__(self, name, value):
        self.__dict[name] = value
    def __delitem__(self, name):
        del self.__dict[name]

    # Object-like access / updates
    def __getattr__(self, name):
        return self[name]

    def __setattr__(self, name, value):
        self[name] = value
    def __delattr__(self, name):
        del self[name]

    def __repr__(self):
        return "%s(%r)" % (type(self).__name__, self.__dict)
    def __str__(self):
        return str(self.__dict)

Example usage:

d = {'a': 'b', 1: 2}
dd = Dictate(d)
assert dd.a == 'b'  # Access like an object
assert dd[1] == 2  # Access like a dict
# Updates affect d
dd.c = 'd'
assert d['c'] == 'd'
del dd.a
del dd[1]
# Inner dicts are mapped
dd.e = {}
dd.e.f = 'g'
assert dd['e'].f == 'g'
assert d == {'c': 'd', 'e': {'f': 'g'}}

A couple of scenarios might help illustrate the purpose of access and refresh tokens and the engineering trade-offs in designing an oauth2 (or any other auth) system:

Web app scenario

In the web app scenario you have a couple of options:

1. if you have your own session management, store both the access_token and refresh_token against your session id in session state on your session state service. When a page is requested by the user that requires you to access the resource use the access_token and if the access_token has expired use the refresh_token to get the new one.

Let's imagine that someone manages to hijack your session. The only thing that is possible is to request your pages.

2. if you don't have session management, put the access_token in a cookie and use that as a session. Then, whenever the user requests pages from your web server send up the access_token. Your app server could refresh the access_token if need be.

Comparing 1 and 2:

In 1, access_token and refresh_token only travel over the wire on the way between the authorzation server (google in your case) and your app server. This would be done on a secure channel. A hacker could hijack the session but they would only be able to interact with your web app. In 2, the hacker could take the access_token away and form their own requests to the resources that the user has granted access to. Even if the hacker gets a hold of the access_token they will only have a short window in which they can access the resources.

Either way the refresh_token and clientid/secret are only known to the server making it impossible from the web browser to obtain long term access.

Let's imagine you are implementing oauth2 and set a long timeout on the access token:

In 1) There's not much difference here between a short and long access token since it's hidden in the app server. In 2) someone could get the access_token in the browser and then use it to directly access the user's resources for a long time.

Mobile scenario

On the mobile, there are a couple of scenarios that I know of:

1. Store clientid/secret on the device and have the device orchestrate obtaining access to the user's resources.

2. Use a backend app server to hold the clientid/secret and have it do the orchestration. Use the access_token as a kind of session key and pass it between the client and the app server.

Comparing 1 and 2

In 1) Once you have clientid/secret on the device they aren't secret any more. Anyone can decompile and then start acting as though they are you, with the permission of the user of course. The access_token and refresh_token are also in memory and could be accessed on a compromised device which means someone could act as your app without the user giving their credentials. In this scenario the length of the access_token makes no difference to the hackability since refresh_token is in the same place as access_token. In 2) the clientid/secret nor the refresh token are compromised. Here the length of the access_token expiry determines how long a hacker could access the users resources, should they get hold of it.

Expiry lengths

Here it depends upon what you're securing with your auth system as to how long your access_token expiry should be. If it's something particularly valuable to the user it should be short. Something less valuable, it can be longer.

Some people like google don't expire the refresh_token. Some like stackflow do. The decision on the expiry is a trade-off between user ease and security. The length of the refresh token is related to the user return length, i.e. set the refresh to how often the user returns to your app. If the refresh token doesn't expire the only way they are revoked is with an explicit revoke. Normally, a log on wouldn't revoke.

Hope that rather length post is useful.
