1. Close your project.
2. Go to folder settings and select show hidden folders option.
3. Open the folder where your application is. You will see a .vs folder.
4. Open the .vs folder, you will see a config folder in it. Delete its content.
5. Run Visual Studio in admin mode. Open your solution from the File menu.
6. Clean your solution.
7. Build it.
8. Run it and voila!

I do not recommend deleting IIS Express folder or messing with the config file in it.

In my case I had to enable SchUseStrongCrypto for .Net This forces the server to make connection by using TLS 1.0, 1.1 or 1.2. Without SchUseStrongCrypto enabled the connection was trying to use SSL 3.0, which was disabled at my remote endpoint.

Registry keys to enable use of strong crypto:

[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\.NetFramework\v4.0.30319]
"SchUseStrongCrypto"=dword:00000001

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\v4.0.30319]
"SchUseStrongCrypto"=dword:00000001

When running the development server - which is what you get by running app.run(), you get a single synchronous process, which means at most 1 request is being processed at a time.

By sticking Gunicorn in front of it in its default configuration and simply increasing the number of --workers, what you get is essentially a number of processes (managed by Gunicorn) that each behave like the app.run() development server. 4 workers == 4 concurrent requests. This is because Gunicorn uses its included sync worker type by default.

It is important to note that Gunicorn also includes asynchronous workers, namely eventlet and gevent (and also tornado, but that's best used with the Tornado framework, it seems). By specifying one of these async workers with the --worker-class flag, what you get is Gunicorn managing a number of async processes, each of which managing its own concurrency. These processes don't use threads, but instead coroutines. Basically, within each process, still only 1 thing can be happening at a time (1 thread), but objects can be 'paused' when they are waiting on external processes to finish (think database queries or waiting on network I/O).

This means, if you're using one of Gunicorn's async workers, each worker can handle many more than a single request at a time. Just how many workers is best depends on the nature of your app, its environment, the hardware it runs on, etc. More details can be found on Gunicorn's design page and notes on how gevent works on its intro page.

If you are coming from java background the concept of class in scala is kind of similar to Java, but class in scala cant contain static members.

Objects in scala are singleton type you call methods inside it using object name, in scala object is a keyword and in java object is a instance of class

As of matplotlib v1.4.0rc4, a remove method has been added to the legend object.

Usage:

ax.get_legend().remove()

or

legend = ax.legend(...)
...
legend.remove()

See here for the commit where this was introduced.

Follow the steps below:

1- git stash
2- git add .
3- git commit -m "your commit message"

If you're simply locking an object, I'd prefer to use synchronized

Example:

Lock.acquire();
doSomethingNifty(); // Throws a NPE!
Lock.release(); // Oh noes, we never release the lock!

You have to explicitly do try{} finally{} everywhere.

Whereas with synchronized, it's super clear and impossible to get wrong:

synchronized(myObject) {
    doSomethingNifty();
}

That said, Locks may be more useful for more complicated things where you can't acquire and release in such a clean manner. I would honestly prefer to avoid using bare Locks in the first place, and just go with a more sophisticated concurrency control such as a CyclicBarrier or a LinkedBlockingQueue, if they meet your needs.

I've never had a reason to use wait() or notify() but there may be some good ones.

If you want the cells to resize depending on the content, then you must not specify a width to the table, the rows, or the cells.

If you don't want word wrap, assign the CSS style white-space: nowrap to the cells.

This was an old question, but existing answers ignore the serious issue of throwing away any custom attributes when you regenerate the model. I am adding a more detailed answer to cover the current options available.

You have 3 options:

• Add a [DisplayName("Name goes here")] attribute to the data model class. The downside is that this is thrown away whenever you regenerate the data models.
• Add a string parameter to your Html.LabelFor. e.g. @Html.LabelFor(model => model.SomekingStatus, "My New Label", new { @class = "control-label"}) Reference: https://msdn.microsoft.com/en-us/library/system.web.mvc.html.labelextensions.labelfor(v=vs.118).aspx The downside to this is that you must repeat the label in every view.
• Third option. Use a meta-data class attached to the data class (details follow).

Option 3 - Add a Meta-Data Class:

Microsoft allows for decorating properties on an Entity Framework class, without modifying the existing class! This by having meta-data classes that attach to your database classes (effectively a sideways extension of your EF class). This allow attributes to be added to the associated class and not to the class itself so the changes are not lost when you regenerate the data models.

For example, if your data class is MyModel with a SomekingStatus property, you could do it like this:

First declare a partial class of the same name (and using the same namespace), which allows you to add a class attribute without being overridden:

[MetadataType(typeof(MyModelMetaData))]
public partial class MyModel
{
}

All generated data model classes are partial classes, which allow you to add extra properties and methods by simply creating more classes of the same name (this is very handy and I often use it e.g. to provide formatted string versions of other field types in the model).

Step 2: add a metatadata class referenced by your new partial class:

public class MyModelMetaData
{
    // Apply DisplayNameAttribute (or any other attributes)
    [DisplayName("My New Label")]
    public string SomekingStatus;
}

Reference: https://msdn.microsoft.com/en-us/library/system.componentmodel.dataannotations.metadatatypeattribute(v=vs.110).aspx

Notes:

• From memory, if you start using a metadata class, it may ignore existing attributes on the actual class ([required] etc) so you may need to duplicate those in the Meta-data class.
• This does not operate by magic and will not just work with any classes. The code that looks for UI decoration attributes is designed to look for a meta-data class first.

Adding to what @KyleMit said, consider using:

• col-md-* classes for the larger outer columns
• col-xs-* classes for the smaller inner columns

This will be useful when you view the page on different screen sizes.

On a small screen, the wrapping of larger outer columns will then happen while maintaining the smaller inner columns, if possible

As the multitude of answers indicate, there are lots of different ways to address this issue. Not all of them address what is my number one issue, and what seems to be the asker's priority, as well: The ability to launch from Spotlight.

Here's the solution that works well for me, and should work with any OS X and XCode versions. I've tested it on OS X 10.11 and XCode 7.3.

Initial setup does require launching XCode, but after that, you won't need to just to get to the Simulator.

Setup

1. Launch XCode
2. From the XCode menu, select Open Developer Tool > Simulator
3. In the dock, control (or right) click on the Simulator icon
4. Select Options > Show in Finder
5. While holding down Command and Option, drag the Simulator icon to the applications directory. This creates an alias to it.
6. If desired, rename the alias from "Simulator" to "iOS Simulator". Whatever you name it is what it will show up as in Spotlight.

Note: There are other ways to get to the location of the Simulator app (steps 1-4), such as using Go to Folder… in the Finder, but those require knowing the location of the Simulator to begin with. Since that has changed from version to version of XCode, this way should work regardless of these changes.

Use

1. Launch Spotlight (command-space, etc.)
2. Type "simulator" or "ios" (if you renamed the alias).
3. If necessary, use the down arrow to scroll to the Simulator alias. Eventually, spotlight should learn and make the alias the top choice so you can skip this step.
4. Hit return

You can use the file Object to get the length of the file to initialize your array:

int length = Long.valueOf(file.length()).intValue();
byte[] byteArray = new byte[length];

The regex below will match both numbers from your example.

\b\d[\d,.]*\b

It will return 5000 and 99,999.99998713 - matching your requirements.

From the Console docs in MSDN:

You can solve this problem by setting the TextWriter.NewLine property of the Out or Error property to another line termination string. For example, the C# statement, Console.Error.NewLine = "\r\n\r\n";, sets the line termination string for the standard error output stream to two carriage return and line feed sequences. Then you can explicitly call the WriteLine method of the error output stream object, as in the C# statement, Console.Error.WriteLine();

So - I did this:

Console.Out.Newline = String.Empty;

Then I am able to control the output myself;

Console.WriteLine("Starting item 1:");
    Item1();
Console.WriteLine("OK.\nStarting Item2:");

Another way of getting there.

JSON.stringify(data).length return string length not Object length, you can use Object.keys.

<% for(var i=0; i < Object.keys(data).length ; i++) {%>

A simple approach is to output as html, which pandas does out of the box:

df.to_html('temp.html')

I struggled a lot to resolve it Nothing seemed to work for me.

The steps I followed are mentioned here.

1 - Go to your App settings.

2 - Click on Add domain.

3 - A dialog will open & will ask you to enter the desired domain. (Please add it starting with www for instance - www.abcd.com )

4 - One added click on Next to move to the next dialog.

5 - After adding the domain you will get the DNS target, Now you need to navigate to GoDaddy and follow the following steps.

6 - Navigate to https://dcc.godaddy.com/domains & click on your domain.

7 - Once clicked you will navigate to https://dcc.godaddy.com/control/yourdomain/settings

8 - Scroll down to the bottom you will see Manage DNS.

9 - It will navigate you to DNS settings then add the entry similar to mentioned below and delete all other CNAME records. Here the value of points is your DNS target that you got in the 4th Step.

10 - Then after some time your site should be mapped to the Heroku app URL.

There is a handy bash utility - dos2unix - which is a DOS/MAC to UNIX text file format converter, that if not already installed on your distro, should be able to be easily installed via a package manager. dos2unix man page

You should choose access via fields over access via properties. With fields you can limit the data sent and received. With via properties you can send more data as a host, and set G denominations (which factory set most of the properties in total).

IBOutlet

• It is a property.
• When the nib(IB) file is loaded, it becomes part of encapsulated data which connects to an instance variable.
• Each connection is unarchived and reestablished.

IBAction

• Attribute indicates that the method is an action that you can connect to from your storyboard in Interface Builder.

Here's a one-liner using Maven:

mvn dependency:get -Dartifact=mysql:mysql-connector-java:5.1.38

Then, with default settings, it's available in:

$HOME/.m2/repository/mysql/mysql-connector-java/5.1.38/mysql-connector-java-5.1.38.jar

Just replace the version number if you need a different one.

This feature will never be part of Sass. One major reason is import order. In CSS, the files imported last can override the styles stated before. If you import a directory, how can you determine import order? There's no way that doesn't introduce some new level of complexity. By keeping a list of imports (as you did in your example), you're being explicit with import order. This is essential if you want to be able to confidently override styles that are defined in another file or write mixins in one file and use them in another.

For a more thorough discussion, view this closed feature request here:

Your Fragment can subclass ListFragment.
And onCreateView() from ListFragment will return a ListView you can then populate.

I suggest to use utf8mb4_unicode_ci, which is based on the Unicode standard for sorting and comparison, which sorts accurately in a very wide range of languages.

Try this in Sql Server

SELECT 
      start_date as firstdate,end_date as seconddate
       ,cast(datediff(MI,start_date,end_date)as decimal(10,3)) as minutediff
      ,cast(cast(cast(datediff(MI,start_date,end_date)as decimal(10,3)) / (24*60) as int ) as varchar(10)) + ' ' + 'Days' + ' ' 
      + cast(cast((cast(datediff(MI,start_date,end_date)as decimal(10,3)) / (24*60) - 
        floor(cast(datediff(MI,start_date,end_date)as decimal(10,3)) / (24*60)) ) * 24 as int) as varchar(10)) + ':' 

     + cast( cast(((cast(datediff(MI,start_date,end_date)as decimal(10,3)) / (24*60) 
      - floor(cast(datediff(MI,start_date,end_date)as decimal(10,3)) / (24*60)))*24
        -
        cast(floor((cast(datediff(MI,start_date,end_date)as decimal(10,3)) / (24*60) 
      - floor(cast(datediff(MI,start_date,end_date)as decimal(10,3)) / (24*60)))*24) as decimal)) * 60 as int) as varchar(10))

    FROM [AdventureWorks2012].dbo.learndate

<xsl:variable name="count" select="count(/Property/long = $parPropId)"/>

Un-tested but I think that should work. I'm assuming the Property nodes are direct children of the root node and therefor taking out your descendant selector for peformance

Note most of the other techniques described here break down if you're dealing with characters outside of the BMP (Unicode Basic Multilingual Plane), i.e. code points that are outside of the u0000-uFFFF range. This will only happen rarely, since the code points outside this are mostly assigned to dead languages. But there are some useful characters outside this, for example some code points used for mathematical notation, and some used to encode proper names in Chinese.

In that case your code will be:

String str = "....";
int offset = 0, strLen = str.length();
while (offset < strLen) {
  int curChar = str.codePointAt(offset);
  offset += Character.charCount(curChar);
  // do something with curChar
}

The Character.charCount(int) method requires Java 5+.

type.convert(f) on a factor whose levels are completely numeric is another base option.

Performance-wise it's about equivalent to as.numeric(as.character(f)) but not nearly as quick as as.numeric(levels(f))[f].

identical(type.convert(f), as.numeric(levels(f))[f])

[1] TRUE

That said, if the reason the vector was created as a factor in the first instance has not been addressed (i.e. it likely contained some characters that could not be coerced to numeric) then this approach won't work and it will return a factor.

levels(f)[1] <- "some character level"
identical(type.convert(f), as.numeric(levels(f))[f])

[1] FALSE

Since this question asked for non-Python versions, here's JavaScript:

a.methodname = function () { console.log("Yay, a new method!") }

Run it with -e or set -e at the top.

Also look at set -u.

I'm not familiar with DB2, but have you tried COALESCE?

ie:

SELECT Product.ID, COALESCE(product.Name, "Internal") AS ProductName
FROM Product

That's because you created a Web Site instead of a Web Application. The cs/vb files can only be seen in a Web Application, but in a website you can't have a separate cs/vb file.

Edit: In the website you can add a cs file behavior like..

<%@ Application CodeFile="Global.asax.cs" Inherits="ApplicationName.MyApplication" Language="C#" %>

~/Global.asax.cs:

namespace ApplicationName
{
    public partial class MyApplication : System.Web.HttpApplication
    {
        protected void Application_Start()
        {
        }
    }
}

Try with this combination of Lambda expressions:

employees.ToList().ForEach(emp => 
{
    collection.AddRange(emp.Departments);
    emp.Departments.ToList().ForEach(dept => dept.SomeProperty = null);                    
});

Do you have a local user.name or user.email that's overriding the global one?

git config --list --global | grep user
  user.name=YOUR NAME
  user.email=YOUR@EMAIL
git config --list --local | grep user
  user.name=YOUR NAME
  user.email=

If so, remove them

git config --unset --local user.name
git config --unset --local user.email

The local settings are per-clone, so you'll have to unset the local user.name and user.email for each of the repos on your machine.

You can use a DOMParser, like so:

var xmlString = "<div id='foo'><a href='#'>Link</a><span></span></div>";_x000D_
var doc = new DOMParser().parseFromString(xmlString, "text/xml");_x000D_
console.log(doc.firstChild.innerHTML); // => <a href="#">Link..._x000D_
console.log(doc.firstChild.firstChild.innerHTML); // => Link

What do you actually want to achieve? What your code does is it tries to connect to a server located at 192.168.1.104:4000. Is this the address of a server that sends the messages (because this looks like a client-side code)? If I run fake server locally:

$ nc -l 4000

...and change socket address to localhost:4000, it will work and try to read something from nc-created server.

What you probably want is to create a ServerSocket and listen on it:

ServerSocket serverSocket = new ServerSocket(4000);
Socket socket = serverSocket.accept();

The second line will block until some other piece of software connects to your machine on port 4000. Then you can read from the returned socket. Look at this tutorial, this is actually a very broad topic (threading, protocols...)

I've read numerous forums and tried play apps but not found a solution until now.

My scenario I believe is similar to yours, but I will clarify to help others. I have a locally hosted website and web services to be used by my android application. I need to have this working on the road for demonstration with only my laptop and no network connection.

Note: Using my iPhone as a wifi hotspot and connecting both my pc and my android device worked, but the iPhone 4S connection is slow and dropped out regularly.

My solution is as follows:

• Unplug network cables on PC and turn off wifi.
• Turn off wifi on android device
• Connect android to pc via USB
• Turn on "USB Tethering" in the android menu. (Under networks->more...->Tethering and portable hotspot")
• Get the IP of your computer that has been assigned by the USB tether cable. (open command prompt and type "ipconfig" then look for the IP that the USB network adapter has assigned)
• Open a browser on the PC using the IP address found instead of localhost to test. i.e. http://192.168.1.1/myWebSite
• Open a browser on the android and test it works

public static IEnumerable<DateTime> GetDateRange(DateTime startDate, DateTime endDate)
{
    if (endDate < startDate)
        throw new ArgumentException("endDate must be greater than or equal to startDate");

    while (startDate <= endDate)
    {
        yield return startDate;
        startDate = startDate.AddDays(1);
    }
}

If you want to use Codeblocks and Graphics.h,you can use Codeblocks-EP(I used it when I was learning C in college) then you can try

It has templates for WinBGIm projects installed and all the necessary libraries pre-installed.

Just go to ![(Help->Install New Software)]

Then Work with: --All Available Sites--

Then type egit underneath and wait (may take a while) ! Then click the checkbox and install.

In Net Core 3.0:

I was not able to find a way to Reset Migrations.

I also ran into problems with broken migrations, and the answers provided here didn't work for me. I have a .Net Core 3.0 web API, and somewhere in the last month I edited the database directly. Yes, I did a bad, bad thing.

Strategies suggested here resulted in a number of errors in Package Manager Console:

• A migration of that name already exists
• Could not find the snapshot
• 'Force' is not a recognized parameter

Granted, I may have missed a step or missed clearing out the correct files, but I found that there are ways to clean this up without as much brute force:

• Remove-Migration from the PMC for each migration by name, in reverse order of creation, up to and including the broken migration
• Add-Migration to create a new migration which will be the delta between the last good migration up to the current schema

Now when the web API is started with an empty database, it correctly creates all the tables and properties to match the entity models.

HTH!

Many right answers but in case you want it in a float, directly, without using regex:

x= '$123.45M'

float(''.join(c for c in x if (c.isdigit() or c =='.'))

123.45

You can change the point for a comma depending on your needs.

change for this if you know your number is an integer

x='$1123'    
int(''.join(c for c in x if c.isdigit())

1123

Identify the hash of the commit, using git log, then use git revert <commit> to create a new commit that removes these changes. In a way, git revert is the converse of git cherry-pick -- the latter applies the patch to a branch that's missing it, the former removes it from a branch that has it.

You can use the dir step, example:

dir("folder") {
    sh "pwd"
}

The folder can be relative or absolute path.

Command EXPOSE in your Dockerfile lets you bind container's port to some port on the host machine but it doesn't do anything else. When running container, to bind ports specify -p option.

So let's say you expose port 5000. After building the image when you run the container, run docker run -p 5000:5000 name. This binds container's port 5000 to your laptop/computers port 5000 and that portforwarding lets container to receive outside requests.

This should do it.

What about angular-scroll, it's actively maintained and there is no dependency to jQuery..

Two years late, but I have the solution you're looking for. Not intending to take credit form the original author, here's a plugin which I found works exceptionally well for what you need, but gets all possible styles in all browsers, even IE.

Warning: This code generates a lot of output, and should be used sparingly. It not only copies all standard CSS properties, but also all vendor CSS properties for that browser.

jquery.getStyleObject.js:

/*
 * getStyleObject Plugin for jQuery JavaScript Library
 * From: http://upshots.org/?p=112
 */

(function($){
    $.fn.getStyleObject = function(){
        var dom = this.get(0);
        var style;
        var returns = {};
        if(window.getComputedStyle){
            var camelize = function(a,b){
                return b.toUpperCase();
            };
            style = window.getComputedStyle(dom, null);
            for(var i = 0, l = style.length; i < l; i++){
                var prop = style[i];
                var camel = prop.replace(/\-([a-z])/g, camelize);
                var val = style.getPropertyValue(prop);
                returns[camel] = val;
            };
            return returns;
        };
        if(style = dom.currentStyle){
            for(var prop in style){
                returns[prop] = style[prop];
            };
            return returns;
        };
        return this.css();
    }
})(jQuery);

Basic usage is pretty simple, but he's written a function for that as well:

$.fn.copyCSS = function(source){
  var styles = $(source).getStyleObject();
  this.css(styles);
}

Hope that helps.

I just found this code snippet simple and functional, try :

        mLatitudeText.setText(String.valueOf(mLastLocation.getLatitude()));
        mLongitudeText.setText(String.valueOf(mLastLocation.getLongitude()));
    }

There is an undocumented method called device_lib.list_local_devices() that enables you to list the devices available in the local process. (N.B. As an undocumented method, this is subject to backwards incompatible changes.) The function returns a list of DeviceAttributes protocol buffer objects. You can extract a list of string device names for the GPU devices as follows:

from tensorflow.python.client import device_lib

def get_available_gpus():
    local_device_protos = device_lib.list_local_devices()
    return [x.name for x in local_device_protos if x.device_type == 'GPU']

Note that (at least up to TensorFlow 1.4), calling device_lib.list_local_devices() will run some initialization code that, by default, will allocate all of the GPU memory on all of the devices (GitHub issue). To avoid this, first create a session with an explicitly small per_process_gpu_fraction, or allow_growth=True, to prevent all of the memory being allocated. See this question for more details.

You can find it via:

$(yourEl).tabs({
    activate: function(event, ui) {
        console.log(ui.newPanel.index());
    }
});

You can easily create your own extension method on IEnumerable or IQueryable:

public static IOrderedEnumerable<TSource> OrderByWithDirection<TSource,TKey>
    (this IEnumerable<TSource> source,
     Func<TSource, TKey> keySelector,
     bool descending)
{
    return descending ? source.OrderByDescending(keySelector)
                      : source.OrderBy(keySelector);
}

public static IOrderedQueryable<TSource> OrderByWithDirection<TSource,TKey>
    (this IQueryable<TSource> source,
     Expression<Func<TSource, TKey>> keySelector,
     bool descending)
{
    return descending ? source.OrderByDescending(keySelector)
                      : source.OrderBy(keySelector);
}

Yes, you lose the ability to use a query expression here - but frankly I don't think you're actually benefiting from a query expression anyway in this case. Query expressions are great for complex things, but if you're only doing a single operation it's simpler to just put that one operation:

var query = dataList.OrderByWithDirection(x => x.Property, direction);

I have had this problem frequently with multiple concurrent goroutines.

It may or may not be a good pattern, but I define a a struct for my workers with a quit channel and field for the worker state:

type Worker struct {
    data chan struct
    quit chan bool
    stopped bool
}

Then you can have a controller call a stop function for the worker:

func (w *Worker) Stop() {
    w.quit <- true
    w.stopped = true
}

func (w *Worker) eventloop() {
    for {
        if w.Stopped {
            return
        }
        select {
            case d := <-w.data:
                //DO something
                if w.Stopped {
                    return
                }
            case <-w.quit:
                return
        }
    }
}

This gives you a pretty good way to get a clean stop on your workers without anything hanging or generating errors, which is especially good when running in a container.

To count the columns of your table precisely, you can get form information_schema.columns with passing your desired Database(Schema) Name and Table Name.

Reference the following Code:

SELECT count(*)
FROM information_schema.columns
WHERE table_schema = 'myDB'  
AND table_name = 'table1';

If you're looking to use the standard construct of element = element1 || element2 where JavaScript will return the first one that is truthy, you could do exactly that:

element = $('#someParentElement .somethingToBeFound') || $('#someParentElement .somethingElseToBeFound');

which would return the first element that is actually found. But a better way would probably be to use the jQuery selector comma construct (which returns an array of found elements) in this fashion:

element = $('#someParentElement').find('.somethingToBeFound, .somethingElseToBeFound')[0];

which will return the first found element.

I use that from time to time to find either an active element in a list or some default element if there is no active element. For example:

element = $('ul#someList').find('li.active, li:first')[0] 

which will return any li with a class of active or, should there be none, will just return the last li.

Either will work. There are potential performance penalties, though, as the || will stop processing as soon as it finds something truthy whereas the array approach will try to find all elements even if it has found one already. Then again, using the || construct could potentially have performance issues if it has to go through several selectors before finding the one it will return, because it has to call the main jQuery object for each one (I really don't know if this is a performance hit or not, it just seems logical that it could be). In general, though, I use the array approach when the selector is a rather long string.

The error you're getting is that self.adj doesn't already have a key 0. You're trying to append to a list that doesn't exist yet.

Consider using a defaultdict instead, replacing this line (in __init__):

self.adj = {}

with this:

self.adj = defaultdict(list)

You'll need to import at the top:

from collections import defaultdict

Now rather than raise a KeyError, self.adj[0].append(edge) will create a list automatically to append to.

This one shows SQL that is currently "ACTIVE":-

select S.USERNAME, s.sid, s.osuser, t.sql_id, sql_text
from v$sqltext_with_newlines t,V$SESSION s
where t.address =s.sql_address
and t.hash_value = s.sql_hash_value
and s.status = 'ACTIVE'
and s.username <> 'SYSTEM'
order by s.sid,t.piece
/

This shows locks. Sometimes things are going slow, but it's because it is blocked waiting for a lock:

select
  object_name, 
  object_type, 
  session_id, 
  type,         -- Type or system/user lock
  lmode,        -- lock mode in which session holds lock
  request, 
  block, 
  ctime         -- Time since current mode was granted
from
  v$locked_object, all_objects, v$lock
where
  v$locked_object.object_id = all_objects.object_id AND
  v$lock.id1 = all_objects.object_id AND
  v$lock.sid = v$locked_object.session_id
order by
  session_id, ctime desc, object_name
/

This is a good one for finding long operations (e.g. full table scans). If it is because of lots of short operations, nothing will show up.

COLUMN percent FORMAT 999.99 

SELECT sid, to_char(start_time,'hh24:mi:ss') stime, 
message,( sofar/totalwork)* 100 percent 
FROM v$session_longops
WHERE sofar/totalwork < 1
/

As one person may have already suggested,

I passed the ISO 8601 date string directly to moment like so...

`moment.utc('2019-11-03T05:00:00.000Z').format('MM/DD/YYYY')`

or

`moment('2019-11-03T05:00:00.000Z').utc().format('MM/DD/YYYY')`

either of these solutions will give you the same result.

`console.log(moment('2019-11-03T05:00:00.000Z').utc().format('MM/DD/YYYY')) // 11/3/2019`

Assuming that I is your input image and F is its Fourier Transform (i.e. F = fft2(I))

You can use this code:

F = fftshift(F); % Center FFT

F = abs(F); % Get the magnitude
F = log(F+1); % Use log, for perceptual scaling, and +1 since log(0) is undefined
F = mat2gray(F); % Use mat2gray to scale the image between 0 and 1

imshow(F,[]); % Display the result

I get a better result setting this class:

.modal-dialog {
  position: absolute;
  top: 50px;
  right: 100px;
  bottom: 0;
  left: 0;
  z-index: 10040;
  overflow: auto;
  overflow-y: auto;
}

With bootstrap 3.3.7.

(all credits to msnfreaky for the idea...)

You should in fact URI-encode the "invalid" characters. Since the string actually contains the complete URL, it's hard to properly URI-encode it. You don't know which slashes / should be taken into account and which not. You cannot predict that on a raw String beforehand. The problem really needs to be solved at a higher level. Where does that String come from? Is it hardcoded? Then just change it yourself accordingly. Does it come in as user input? Validate it and show error, let the user solve itself.

At any way, if you can ensure that it are only the spaces in URLs which makes it invalid, then you can also just do a string-by-string replace with %20:

URI uri = new URI(string.replace(" ", "%20"));

Or if you can ensure that it's only the part after the last slash which needs to be URI-encoded, then you can also just do so with help of android.net.Uri utility class:

int pos = string.lastIndexOf('/') + 1;
URI uri = new URI(string.substring(0, pos) + Uri.encode(string.substring(pos)));

Do note that URLEncoder is insuitable for the task as it's designed to encode query string parameter names/values as per application/x-www-form-urlencoded rules (as used in HTML forms). See also Java URL encoding of query string parameters.

I like to use: ArgumentException, ArgumentNullException, and ArgumentOutOfRangeException.

• ArgumentException – Something is wrong with the argument.
• ArgumentNullException – Argument is null.
• ArgumentOutOfRangeException – I don’t use this one much, but a common use is indexing into a collection, and giving an index which is to large.

There are other options, too, that do not focus so much on the argument itself, but rather judge the call as a whole:

• InvalidOperationException – The argument might be OK, but not in the current state of the object. ^{_{Credit goes to STW (previously Yoooder). Vote his answer up as well.}}
• NotSupportedException – The arguments passed in are valid, but just not supported in this implementation. Imagine an FTP client, and you pass a command in that the client doesn’t support.

The trick is to throw the exception that best expresses why the method cannot be called the way it is. Ideally, the exception should be detailed about what went wrong, why it is wrong, and how to fix it.

I love when error messages point to help, documentation, or other resources. For example, Microsoft did a good first step with their KB articles, e.g. “Why do I receive an "Operation aborted" error message when I visit a Web page in Internet Explorer?”. When you encounter the error, they point you to the KB article in the error message. What they don’t do well is that they don’t tell you, why specifically it failed.

^{_{Thanks to STW (ex Yoooder) again for the comments.}}

In response to your followup, I would throw an ArgumentOutOfRangeException. Look at what MSDN says about this exception:

ArgumentOutOfRangeException is thrown when a method is invoked and at least one of the arguments passed to the method is not null reference (Nothing in Visual Basic) and does not contain a valid value.

So, in this case, you are passing a value, but that is not a valid value, since your range is 1–12. However, the way you document it makes it clear, what your API throws. Because although I might say ArgumentOutOfRangeException, another developer might say ArgumentException. Make it easy and document the behavior.

dict.iteritems is gone in Python3.x So use iter(dict.items()) to get the same output and memory alocation

In your view, you have to cast it back to the original type. Without the cast, it's just an object.

<td>@((ViewBag.data as ICollection<Person>).First().FirstName)</td>

ViewBag is a C# 4 dynamic type. Entities returned from it are also dynamic unless cast. However, extension methods like .First() and all the other Linq ones do not work with dynamics.

Edit - to address the comment:

If you want to display the whole list, it's as simple as this:

<ul>
    @foreach (var person in ViewBag.data)
    {
        <li>@person.FirstName</li>
    }
</ul>

Extension methods like .First() won't work, but this will.

Your function has a couple of smallint parameters.
But in the call, you are using numeric literals that are presumed to be type integer.

A string literal or string constant ('123') is not typed immediately. It remains type "unknown" until assigned or cast explicitly.

However, a numeric literal or numeric constant is typed immediately. Per documentation:

A numeric constant that contains neither a decimal point nor an exponent is initially presumed to be type integer if its value fits in type integer (32 bits); otherwise it is presumed to be type bigint if its value fits in type bigint (64 bits); otherwise it is taken to be type numeric. Constants that contain decimal points and/or exponents are always initially presumed to be type numeric.

More explanation and links in this related answer:

• PostgreSQL ERROR: function to_tsvector(character varying, unknown) does not exist

Solution

Add explicit casts for the smallint parameters or quote them.

Demo

CREATE OR REPLACE FUNCTION f_typetest(smallint)
  RETURNS bool AS 'SELECT TRUE' LANGUAGE sql;

Incorrect call:

SELECT * FROM f_typetest(1);

Correct calls:

SELECT * FROM f_typetest('1');
SELECT * FROM f_typetest(smallint '1');
SELECT * FROM f_typetest(1::int2);
SELECT * FROM f_typetest('1'::int2);

Due to the locking implementation issues, MySQL does not allow referencing the affected table with DELETE or UPDATE.

You need to make a JOIN here instead:

DELETE  gc.*
FROM    guide_category AS gc 
LEFT JOIN
        guide AS g 
ON      g.id_guide = gc.id_guide
WHERE   g.title IS NULL

or just use a NOT IN:

DELETE  
FROM    guide_category AS gc 
WHERE   id_guide NOT IN
        (
        SELECT  id_guide
        FROM    guide
        )

We implemented a ngModelChange observable directive that sends all model changes through an event emitter that you instantiate in your own component. You simply have to bind your event emitter to the directive.

See: https://github.com/atomicbits/angular2-modelchangeobservable

In html, bind your event emitter (countryChanged in this example):

<input [(ngModel)]="country.name"
       [modelChangeObservable]="countryChanged" 
       placeholder="Country"
       name="country" id="country"></input>

In your typescript component, do some async operations on the EventEmitter:

import ...
import {ModelChangeObservable} from './model-change-observable.directive'


@Component({
    selector: 'my-component',
    directives: [ModelChangeObservable],
    providers: [],
    templateUrl: 'my-component.html'
})

export class MyComponent {

    @Input()
    country: Country

    selectedCountries:Country[]
    countries:Country[] = <Country[]>[]
    countryChanged:EventEmitter<string> = new EventEmitter<string>()


    constructor() {

        this.countryChanged
            .filter((text:string) => text.length > 2)
            .debounceTime(300)
            .subscribe((countryName:string) => {
                let query = new RegExp(countryName, 'ig')
                this.selectedCountries = this.countries.filter((country:Country) => {
                    return query.test(country.name)
                })
            })
    }
}

The difference between --save and --save-dev may not be immediately noticeable if you have tried them both on your own projects. So here are a few examples...

Lets say you were building an app that used the moment package to parse and display dates. Your app is a scheduler so it really needs this package to run, as in: cannot run without it. In this case you would use

npm install moment --save

This would create a new value in your package.json

"dependencies": {
   ...
   "moment": "^2.17.1"
}

When you are developing, it really helps to use tools such as test suites and may need jasmine-core and karma. In this case you would use

npm install jasmine-core --save-dev
npm install karma --save-dev

This would also create a new value in your package.json

"devDependencies": {
    ...
    "jasmine-core": "^2.5.2",
    "karma": "^1.4.1",
}

You do not need the test suite to run the app in its normal state, so it is a --save-dev type dependency, nothing more. You can see how if you do not understand what is really happening, it is a bit hard to imagine.

Taken directly from NPM docs docs#dependencies

Dependencies

Dependencies are specified in a simple object that maps a package name to a version range. The version range is a string which has one or more space-separated descriptors. Dependencies can also be identified with a tarball or git URL.

Please do not put test harnesses or transpilers in your dependencies object. See devDependencies, below.

Even in the docs, it asks you to use --save-dev for modules such as test harnesses.

I hope this helps and is clear.

The SQL you posted in your question is one way to do it. Most things in SQL have more than one way to do it.

UPDATE
  [Table1] 
SET
  [Description]=(SELECT [Description] FROM [Table2] t2 WHERE t2.[ID]=Table1.DescriptionID)

If you are planning on running this on a PROD DB, it is best to create a snapshot or mirror of it first and test it out. Verify the data ends up as you expect for a couple records. And if you are satisfied, run it on the real DB.

I was at the pgopen today benchmarks are way faster than mongodb, I believe it was around 500% faster for selects. Pretty much everything was faster at least by at 200% when contrasted with mongodb, than one exception right now is a update which requires completely rewriting the entire json column something mongodb handles better.

The gin indexing on on jsonb sounds amazing.

Also postgres will persist types of jsonb internally and basically match this with types such as numeric, text, boolean etc.

Joins will also be possible using jsonb

Add PLv8 for stored procedures and this will basically be a dream come true for node.js developers.

Being it's stored as binary jsonb will also strip all whitespace, change the ordering of properties and remove duplicate properties using the last occurance of the property.

Besides the index when querying against a jsonb column contrasted to a json column postgres doesn't have to actually run the functionality to convert the text to json on every row which will likely save a vast amount of time alone.

Speaking production, seamless failover/recovery both require a baby sitter
1- Couchbase, there is no seamless failover/recovery, manual intervention is required.

I had the same problem in my grails project. The Bug was, that i overwrite the getter method of a collection field. This returned always a new version of the collection in other thread.

class Entity {
    List collection

    List getCollection() {
        return collection.unique()
    }
}

The solution was to rename the getter method:

class Entity {
    List collection

    List getUniqueCollection() {
        return collection.unique()
    }
}

If in every li you have only one row of text you can put text indent on li. Like this :

ul {
  list-style: disc;
}
ul li {
   text-indent: 5px;
}

or

ul {
 list-style: disc;
}
ul li {
   text-indent: -5px;
}

You can use text.

text(x, y, s, fontsize=12)

text coordinates can be given relative to the axis, so the position of your text will be independent of the size of the plot:

The default transform specifies that text is in data coords, alternatively, you can specify text in axis coords (0,0 is lower-left and 1,1 is upper-right). The example below places text in the center of the axes::

text(0.5, 0.5,'matplotlib',
     horizontalalignment='center',
     verticalalignment='center',
     transform = ax.transAxes)

To prevent the text to interfere with any point of your scatter is more difficult afaik. The easier method is to set y_axis (ymax in ylim((ymin,ymax))) to a value a bit higher than the max y-coordinate of your points. In this way you will always have this free space for the text.

EDIT: here you have an example:

In [17]: from pylab import figure, text, scatter, show
In [18]: f = figure()
In [19]: ax = f.add_subplot(111)
In [20]: scatter([3,5,2,6,8],[5,3,2,1,5])
Out[20]: <matplotlib.collections.CircleCollection object at 0x0000000007439A90>
In [21]: text(0.1, 0.9,'matplotlib', ha='center', va='center', transform=ax.transAxes)
Out[21]: <matplotlib.text.Text object at 0x0000000007415B38>
In [22]:

The ha and va parameters set the alignment of your text relative to the insertion point. ie. ha='left' is a good set to prevent a long text to go out of the left axis when the frame is reduced (made narrower) manually.

you can Try the following snippet:

var str = "How are you doing today?";
var res = str.split("o");
console.log("My Result:",res)

and your output like that

My Result: H,w are y,u d,ing t,day?

You could say that parsing a string of characters is analyzing this string to find tokens, or items and then create a structure from the result.

In your example, calling Integer.parseInt on a string is parsing this string to find an integer.

So, if you have:

String someString = "123";

And then you invoke:

int i = Integer.parseInt( someString );

You're telling java to analyze the "123" string and find an integer there.

Other example:

One of the actions the java compiler does, when it compiles your source code is to "parse" your .java file and create tokens that match the java grammar.

When you fail to write the source code properly ( for instance forget to add a ; at the end of a statement ), it is the parser who identifies the error.

Here's more information: http://en.wikipedia.org/wiki/Parse

I got this error message with a much more recent ssis version (vs 2015 enterprise, i think it's ssis 2016). I will comment here because this is the first reference that comes up when you google this error message. I think it happens mostly with character columns when the source character size is larger than the target character size. I got this message when I was using an ado.net input to ms sql from a teradata database. Funny because the prior oledb writes to ms sql handled all the character conversion perfectly with no coding overrides. The colid number and the a corresponding Destination Input column # you sometimes get with the colid message are worthless. It's not the column when you count down from the top of the mapping or anything like that. If I were microsoft, I'd be embarrased to give an error message that looks like it's pointing at the problem column when it isn't. I found the problem colid by making an educated guess and then changing the input to the mapping to "Ignore" and then rerun and see if the message went away. In my case and in my environment I fixed it by substr( 'ing the Teradata input to the character size of the ms sql declaration for the output column. Check and make sure your input substr propagates through all you data conversions and mappings. In my case it didn't and I had to delete all my Data Conversion's and Mappings and start over again. Again funny that OLEDB just handled it and ADO.net threw the error and had to have all this intervention to make it work. In general you should use OLEDB when your target is MS Sql.

For me I put my dependencies in the wrong spot.

buildscript {
  dependencies {
    //Don't put dependencies here.
  }
}

dependencies {
 //Put them here
}

The double underscore. It mangles the name in such a way that it can't be accessed simply through __fieldName from outside the class, which is what you want to begin with if they're to be private. (Though it's still not very hard to access the field.)

class Foo:
    def __init__(self):
        self.__privateField = 4;
        print self.__privateField # yields 4 no problem

foo = Foo()
foo.__privateField
# AttributeError: Foo instance has no attribute '__privateField'

It will be accessible through _Foo__privateField instead. But it screams "I'M PRIVATE DON'T TOUCH ME", which is better than nothing.

Since this issue happened because calling model another time. Work around to this issue by wrapping your model code in try catch block. typescript code is like this -

         Import {Schema, model} from 'mongoose';
         export function user(){
              try{
                   return model('user', new Schema ({
                            FirstName: String,
                            Last name: String
                     }));
              }
             catch{
                   return model('user');
              }
         }

Similarly you can write code in js too.

Like this:

int main()
{
    int arr[2][5] =
    {
        {1,8,12,20,25},
        {5,9,13,24,26}
    };
}

This should be covered by your C++ textbook: which one are you using?

Anyway, better, consider using std::vector or some ready-made matrix class e.g. from Boost.

It's simple; make a custom cell and take a outlet of button

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
    {
         NSString *identifier = @"identifier";
        customCell *cell = [tableView dequeueReusableCellWithIdentifier:identifier];

    cell.yourButton.tag = indexPath.Row;

- (void)buttonPressedAction:(id)sender

change id in above method to (UIButton *)

You can get the value that which button is being tapped by doing sender.tag.

As @Clarke said, you can use java.io.FilenameFilter to filter the file by specific condition.

As a complementary, I'd like to show how to use java.io.FilenameFilter to search file in current directory and its subdirectory.

The common methods getTargetFiles and printFiles are used to search files and print them.

public class SearchFiles {

    //It's used in dfs
    private Map<String, Boolean> map = new HashMap<String, Boolean>();

    private File root;

    public SearchFiles(File root){
        this.root = root;
    }

    /**
     * List eligible files on current path
     * @param directory
     *      The directory to be searched
     * @return
     *      Eligible files
     */
    private String[] getTargetFiles(File directory){
        if(directory == null){
            return null;
        }

        String[] files = directory.list(new FilenameFilter(){

            @Override
            public boolean accept(File dir, String name) {
                // TODO Auto-generated method stub
                return name.startsWith("Temp") && name.endsWith(".txt");
            }

        });

        return files;
    }

    /**
     * Print all eligible files
     */
    private void printFiles(String[] targets){
        for(String target: targets){
            System.out.println(target);
        }
    }
}

I will demo how to use recursive, bfs and dfs to get the job done.

Recursive:

    /**
 * How many files in the parent directory and its subdirectory <br>
 * depends on how many files in each subdirectory and their subdirectory
 */
private void recursive(File path){

    printFiles(getTargetFiles(path));
    for(File file: path.listFiles()){
        if(file.isDirectory()){
            recursive(file);
        }
    }
    if(path.isDirectory()){
        printFiles(getTargetFiles(path));
    }
}

public static void main(String args[]){
    SearchFiles searcher = new SearchFiles(new File("C:\\example"));
    searcher.recursive(searcher.root);
}

Breadth First Search:

/**
 * Search the node's neighbors firstly before moving to the next level neighbors
 */
private void bfs(){
    if(root == null){
        return;
    }

    Queue<File> queue = new LinkedList<File>();
    queue.add(root);

    while(!queue.isEmpty()){
        File node = queue.remove();
        printFiles(getTargetFiles(node));
        File[] childs = node.listFiles(new FileFilter(){

            @Override
            public boolean accept(File pathname) {
                // TODO Auto-generated method stub
                if(pathname.isDirectory())
                    return true;

                return false;
            }

        });

        if(childs != null){
            for(File child: childs){
                queue.add(child);

        }
    }
}

public static void main(String args[]){
    SearchFiles searcher = new SearchFiles(new File("C:\\example"));
    searcher.bfs();
}

Depth First Search:

 /**
 * Search as far as possible along each branch before backtracking
 */
private void dfs(){

    if(root == null){
        return;
    }

    Stack<File> stack = new Stack<File>();
    stack.push(root);
    map.put(root.getAbsolutePath(), true);
    while(!stack.isEmpty()){
        File node = stack.peek();
        File child = getUnvisitedChild(node);

        if(child != null){
            stack.push(child);
            printFiles(getTargetFiles(child));
            map.put(child.getAbsolutePath(), true);
        }else{
            stack.pop();
        }

    }
}

/**
 * Get unvisited node of the node

 */
private File getUnvisitedChild(File node){

    File[] childs = node.listFiles(new FileFilter(){

        @Override
        public boolean accept(File pathname) {
            // TODO Auto-generated method stub
            if(pathname.isDirectory())
                return true;

            return false;
        }

    });

    if(childs == null){
        return null;
    }

    for(File child: childs){

        if(map.containsKey(child.getAbsolutePath()) == false){
            map.put(child.getAbsolutePath(), false);
        }

        if(map.get(child.getAbsolutePath()) == false){
            return child; 
        }
    }

    return null;
}

public static void main(String args[]){

Try formatting the link like this (looks hellish, but it works in Firefox 3 under Vista for me) :

Best practices on internal and external temporary files:

Internal Cache

If you'd like to cache some data, rather than store it persistently, you should use getCacheDir() to open a File that represents the internal directory where your application should save temporary cache files.

When the device is low on internal storage space, Android may delete these cache files to recover space. However, you should not rely on the system to clean up these files for you. You should always maintain the cache files yourself and stay within a reasonable limit of space consumed, such as 1MB. When the user uninstalls your application, these files are removed.

External Cache

To open a File that represents the external storage directory where you should save cache files, call getExternalCacheDir(). If the user uninstalls your application, these files will be automatically deleted.

Similar to ContextCompat.getExternalFilesDirs(), mentioned above, you can also access a cache directory on a secondary external storage (if available) by calling ContextCompat.getExternalCacheDirs().

Tip: To preserve file space and maintain your app's performance, it's important that you carefully manage your cache files and remove those that aren't needed anymore throughout your app's lifecycle.

int main()
{
  int size;

  std::cin >> size;

  int *array = new int[size];

  delete [] array;

  return 0;
}

Don't forget to delete every array you allocate with new.

Basic Functionality

• Automatically saved local edit history is available with the Local History extension.
• Manually saved local edit history is available with the Checkpoints extension (this is the IntelliJ equivalent to adding tags to the local history).

Advanced Functionality

• None of the extensions mentioned above support edit history when a file is moved or renamed.
• The extensions above only support edit history. They do not support move/delete history, for example, like IntelliJ does.

Open Request

If you'd like to see this feature added natively, along with all of the advanced functionality, I'd suggest upvoting the open GitHub issue here.

Unfortunately, the MinGW-w64 installer you used sometimes has this issue. I myself am not sure about why this happens (I think it has something to do with Sourceforge URL redirection or whatever that the installer currently can't handle properly enough).

Anyways, if you're already planning on using MSYS2, there's no need for that installer.

1. Download MSYS2 from this page (choose 32 or 64-bit according to what version of Windows you are going to use it on, not what kind of executables you want to build, both versions can build both 32 and 64-bit binaries).

2. After the install completes, click on the newly created "MSYS2 Shell" option under either MSYS2 64-bit or MSYS2 32-bit in the Start menu. Update MSYS2 according to the wiki (although I just do a pacman -Syu, ignore all errors and close the window and open a new one, this is not recommended and you should do what the wiki page says).

3. Install a toolchain

   a) for 32-bit:

   pacman -S mingw-w64-i686-gcc
   

   b) for 64-bit:

   pacman -S mingw-w64-x86_64-gcc
   

4. install any libraries/tools you may need. You can search the repositories by doing

   pacman -Ss name_of_something_i_want_to_install
   

   e.g.

   pacman -Ss gsl
   

   and install using

   pacman -S package_name_of_something_i_want_to_install
   

   e.g.

   pacman -S mingw-w64-x86_64-gsl
   

   and from then on the GSL library is automatically found by your MinGW-w64 64-bit compiler!

5. Open a MinGW-w64 shell:

   a) To build 32-bit things, open the "MinGW-w64 32-bit Shell"

   b) To build 64-bit things, open the "MinGW-w64 64-bit Shell"

6. Verify that the compiler is working by doing

   gcc -v
   

If you want to use the toolchains (with installed libraries) outside of the MSYS2 environment, all you need to do is add <MSYS2 root>/mingw32/bin or <MSYS2 root>/mingw64/bin to your PATH.

for anyone like me, who want the best answer but in kotlin, here it is:

class GridItemDecoration(
    val spacing: Int,
    private val spanCount: Int,
    private val includeEdge: Boolean
) :
    RecyclerView.ItemDecoration() {

    /**
     * Applies padding to all sides of the [Rect], which is the container for the view
     */
    override fun getItemOffsets(
        outRect: Rect,
        view: View,
        parent: RecyclerView,
        state: RecyclerView.State
    ) {
        val position = parent.getChildAdapterPosition(view) // item position
        val column = position % spanCount // item column
        if (includeEdge) {
            outRect.left =
                spacing - column * spacing / spanCount // spacing - column * ((1f / spanCount) * spacing)
            outRect.right =
                (column + 1) * spacing / spanCount // (column + 1) * ((1f / spanCount) * spacing)
            if (position < spanCount) { // top edge
                outRect.top = spacing
            }
            outRect.bottom = spacing // item bottom
        } else {
            outRect.left =
                column * spacing / spanCount // column * ((1f / spanCount) * spacing)
            outRect.right =
                spacing - (column + 1) * spacing / spanCount // spacing - (column + 1) * ((1f /    spanCount) * spacing)
            if (position >= spanCount) {
                outRect.top = spacing // item top
            }
        }
    }
}

plus if you want to get the number from dimens.xml and then convert it to raw pixel you can do it easily using getDimensionPixelOffset easily like this:

recyclerView.addItemDecoration(
                GridItemDecoration(
                    resources.getDimensionPixelOffset(R.dimen.h1),
                    3,
                    true
                )
            )

Calculate row means on a subset of columns:

Create a new data.frame which specifies the first column from DF as an column called ID and calculates the mean of all the other fields on that row, and puts that into column entitled 'Means':

data.frame(ID=DF[,1], Means=rowMeans(DF[,-1]))
  ID    Means
1  A 3.666667
2  B 4.333333
3  C 3.333333
4  D 4.666667
5  E 4.333333

This topic is discussed at CProgramming.com:
https://www.cprogramming.com/compilingandlinking.html

Here is what the author there wrote:

Compiling isn't quite the same as creating an executable file! Instead, creating an executable is a multistage process divided into two components: compilation and linking. In reality, even if a program "compiles fine" it might not actually work because of errors during the linking phase. The total process of going from source code files to an executable might better be referred to as a build.

Compilation

Compilation refers to the processing of source code files (.c, .cc, or .cpp) and the creation of an 'object' file. This step doesn't create anything the user can actually run. Instead, the compiler merely produces the machine language instructions that correspond to the source code file that was compiled. For instance, if you compile (but don't link) three separate files, you will have three object files created as output, each with the name .o or .obj (the extension will depend on your compiler). Each of these files contains a translation of your source code file into a machine language file -- but you can't run them yet! You need to turn them into executables your operating system can use. That's where the linker comes in.

Linking

Linking refers to the creation of a single executable file from multiple object files. In this step, it is common that the linker will complain about undefined functions (commonly, main itself). During compilation, if the compiler could not find the definition for a particular function, it would just assume that the function was defined in another file. If this isn't the case, there's no way the compiler would know -- it doesn't look at the contents of more than one file at a time. The linker, on the other hand, may look at multiple files and try to find references for the functions that weren't mentioned.

You might ask why there are separate compilation and linking steps. First, it's probably easier to implement things that way. The compiler does its thing, and the linker does its thing -- by keeping the functions separate, the complexity of the program is reduced. Another (more obvious) advantage is that this allows the creation of large programs without having to redo the compilation step every time a file is changed. Instead, using so called "conditional compilation", it is necessary to compile only those source files that have changed; for the rest, the object files are sufficient input for the linker. Finally, this makes it simple to implement libraries of pre-compiled code: just create object files and link them just like any other object file. (The fact that each file is compiled separately from information contained in other files, incidentally, is called the "separate compilation model".)

To get the full benefits of condition compilation, it's probably easier to get a program to help you than to try and remember which files you've changed since you last compiled. (You could, of course, just recompile every file that has a timestamp greater than the timestamp of the corresponding object file.) If you're working with an integrated development environment (IDE) it may already take care of this for you. If you're using command line tools, there's a nifty utility called make that comes with most *nix distributions. Along with conditional compilation, it has several other nice features for programming, such as allowing different compilations of your program -- for instance, if you have a version producing verbose output for debugging.

Knowing the difference between the compilation phase and the link phase can make it easier to hunt for bugs. Compiler errors are usually syntactic in nature -- a missing semicolon, an extra parenthesis. Linking errors usually have to do with missing or multiple definitions. If you get an error that a function or variable is defined multiple times from the linker, that's a good indication that the error is that two of your source code files have the same function or variable.

I do not think that there is need to hack around the value and label properties, use hidden input fields or to suppress events. You may add your own custom property to each Autocomplete object and then read that property value later.

Here is an example.

$(#yourInputTextBox).autocomplete({
    source: function(request, response) {
        // Do something with request.term (what was keyed in by the user).
        // It could be an AJAX call or some search from local data.
        // To keep this part short, I will do some search from local data.
        // Let's assume we get some results immediately, where
        // results is an array containing objects with some id and name.
        var results = yourSearchClass.search(request.term);

        // Populate the array that will be passed to the response callback.
        var autocompleteObjects = [];
        for (var i = 0; i < results.length; i++) {
            var object = {
                // Used by jQuery Autocomplete to show
                // autocomplete suggestions as well as
                // the text in yourInputTextBox upon selection.
                // Assign them to a value that you want the user to see.
                value: results[i].name;
                label: results[i].name;

                // Put our own custom id here.
                // If you want to, you can even put the result object.
                id: results[i].id;
            };

            autocompleteObjects.push(object);
        }

        // Invoke the response callback.
        response(autocompleteObjects);
    },
    select: function(event, ui) {
        // Retrieve your id here and do something with it.
        console.log(ui.item.id);
    }
});

The documentation mentions you have to pass in an array of objects with label and value properties. However, you may certainly pass in objects with more than these two properties and read them later.

Here is the relevant part I am referring to.

Array: An array can be used for local data. There are two supported formats: An array of strings: [ "Choice1", "Choice2" ] An array of objects with label and value properties: [ { label: "Choice1", value: "value1" }, ... ] The label property is displayed in the suggestion menu. The value will be inserted into the input element when a user selects an item. If just one property is specified, it will be used for both, e.g., if you provide only value properties, the value will also be used as the label.

I would like to suggest an improvement to yanchenko's answer.

Instead of taking the first ip in the X_FORWARDED_FOR list, I take the first one which in not a known internal ip, as some routers don't respect the protocol, and you can see internal ips as the first value of the list.

PRIVATE_IPS_PREFIX = ('10.', '172.', '192.', )

def get_client_ip(request):
    """get the client ip from the request
    """
    remote_address = request.META.get('REMOTE_ADDR')
    # set the default value of the ip to be the REMOTE_ADDR if available
    # else None
    ip = remote_address
    # try to get the first non-proxy ip (not a private ip) from the

    x_forwarded_for = request.META.get('HTTP_X_FORWARDED_FOR')
    if x_forwarded_for:
        proxies = x_forwarded_for.split(',')
        # remove the private ips from the beginning
        while (len(proxies) > 0 and
                proxies[0].startswith(PRIVATE_IPS_PREFIX)):

            ip = proxies[0]

    return ip

I hope this helps fellow Googlers who have the same problem.

Besides using std::find (from algorithm), you can also use std::find_if (which is, IMO, better than std::find), or other find algorithm from this list

#include <list>
#include <algorithm>
#include <iostream>

int main()
{
    std::list<int> myList{ 5, 19, 34, 3, 33 };
    

    auto it = std::find_if( std::begin( myList ),
                            std::end( myList ),
                            [&]( const int v ){ return 0 == ( v % 17 ); } );
        
    if ( myList.end() == it )
    {
        std::cout << "item not found" << std::endl;
    }
    else
    {
        const int pos = std::distance( myList.begin(), it ) + 1;
        std::cout << "item divisible by 17 found at position " << pos << std::endl;
    }
}

This solves the problem of releasing the memory for me!!!

import gc
import pandas as pd

del [[df_1,df_2]]
gc.collect()
df_1=pd.DataFrame()
df_2=pd.DataFrame()

the data-frame will be explicitly set to null

in the above statements

Firstly, the self reference of the dataframe is deleted meaning the dataframe is no longer available to python there after all the references of the dataframe is collected by garbage collector (gc.collect()) and then explicitly set all the references to empty dataframe.

more on the working of garbage collector is well explained in https://stackify.com/python-garbage-collection/

If you have a value that includes a decimal, but the decimal value is negligible (ie: 100.0) and try to int that, you will get an error. It seems silly, but calling float first fixes this.

str(int(float([variable])))

The most common idiom for creating an array without using the inefficient += is something like this, from the output of a loop:

$array = foreach($i in 1..10) { 
  $i
}
$array

####################### && or (Logical AND) ######################
first_command="1"
two_command="2"

if [[ ($first_command == 1) && ($two_command == 2)]];then
 echo "Equal"
fi

When program checks if command, then the program creates a number called exit code, if both conditions are true, exit code is zero (0), otherwise, exit code is positive number. only when displaying Equal if exit code is produced zero (0) that means both conditions are true.

If you are not able to add a property to system.net class library.

Then, add in Global.asax file:

ServicePointManager.SecurityProtocol = (SecurityProtocolType)3072; //TLS 1.2
ServicePointManager.SecurityProtocol = (SecurityProtocolType)768; //TLS 1.1

And you can use it in a function, at the starting line:

ServicePointManager.SecurityProtocol = (SecurityProtocolType)768 | (SecurityProtocolType)3072;

And, it's being useful for STRIPE payment gateway, which only supports TLS 1.1, TLS 1.2.

EDIT: After so many questions on .NET 4.5 is installed on my server or not... here is the screenshot of Registry on my production server:

I have only .NET framework 4.0 installed.

I think your particular problem isn't how to use Glyphicons but understanding how Bootstrap files work together.

Bootstrap requires a specific file structure to work. I see from your code you have this:

<link href="bootstrap.css" rel="stylesheet" media="screen">

Your Bootstrap.css is being loaded from the same location as your page, this would create a problem if you didn't adjust your file structure.

But first, let me recommend you setup your folder structure like so:

/css      <-- Bootstrap.css here
/fonts    <-- Bootstrap fonts here
/img
/js       <-- Bootstrap JavaScript here
index.html

If you notice, this is also how Bootstrap structures its files in its download ZIP.

You then include your Bootstrap file like so:

<link href="css/bootstrap.css" rel="stylesheet" media="screen">
or
<link href="./css/bootstrap.css" rel="stylesheet" media="screen">
or
<link href="/css/bootstrap.css" rel="stylesheet" media="screen">

Depending on your server structure or what you're going for.

The first and second are relative to your file's current directory. The second one is just more explicit by saying "here" (./) first then css folder (/css).

The third is good if you're running a web server, and you can just use relative to root notation as the leading "/" will be always start at the root folder.

So, why do this?

Bootstrap.css has this specific line for Glyphfonts:

@font-face {
    font-family: 'Glyphicons Halflings';
    src: url('../fonts/glyphicons-halflings-regular.eot');
    src: url('../fonts/glyphicons-halflings-regular.eot?#iefix') format('embedded-opentype'), url('../fonts/glyphicons-halflings-regular.woff') format('woff'), url('../fonts/glyphicons-halflings-regular.ttf') format('truetype'), url('../fonts/glyphicons-halflings-regular.svg#glyphicons-halflingsregular') format('svg');
}

What you can see is that that Glyphfonts are loaded by going up one directory ../ and then looking for a folder called /fonts and THEN loading the font file.

The URL address is relative to the location of the CSS file. So, if your CSS file is at the same location like this:

/fonts
Bootstrap.css
index.html

The CSS file is going one level deeper than looking for a /fonts folder.

So, let's say the actual location of these files are:

C:\www\fonts
C:\www\Boostrap.css
C:\www\index.html

The CSS file would technically be looking for a folder at:

C:\fonts

but your folder is actually in:

C:\www\fonts

So see if that helps. You don't have to do anything 'special' to load Bootstrap Glyphicons, except make sure your folder structure is set up appropriately.

When you get that fixed, your HTML should simply be:

<span class="glyphicon glyphicon-comment"></span>

Note, you need both classes. The first class glyphicon sets up the basic styles while glyphicon-comment sets the specific image.

item is most likely a string in your code; the string indices are the ones in the square brackets, e.g., gravatar_id. So I'd first check your data variable to see what you received there; I guess that data is a list of strings (or at least a list containing at least one string) while it should be a list of dictionaries.

var sels = //Here is your array of SELECTs
var json = { };

for(var i = 0, l = sels.length; i < l; i++) {
  json[sels[i].id] = sels[i].value;
}

Actually quite easy to roll your own tester, by abusing Java's method overload ability. Though I'm still curious if there is an official method in the sdk.

Example:

class Typetester {
    void printType(byte x) {
        System.out.println(x + " is an byte");
    }
    void printType(int x) {
        System.out.println(x + " is an int");
    }
    void printType(float x) {
        System.out.println(x + " is an float");
    }
    void printType(double x) {
        System.out.println(x + " is an double");
    }
    void printType(char x) {
        System.out.println(x + " is an char");
    }
}

then:

Typetester t = new Typetester();
t.printType( yourVariable );

CURRENT_DATE and CURRENT_TIMESTAMP return the current date and time in the session time zone.

SYSDATE and SYSTIMESTAMP return the system date and time - that is, of the system on which the database resides.

If your client session isn't in the same timezone as the server the database is on (or says it isn't anyway, via your NLS settings), mixing the SYS* and CURRENT_* functions will return different values. They are all correct, they just represent different things. It looks like your server is (or thinks it is) in a +4:00 timezone, while your client session is in a +4:30 timezone.

You might also see small differences in the time if the clocks aren't synchronised, which doesn't seem to be an issue here.

This timer will fire a "Hello" alertbox after 30 seconds. However, everytime you click the reset timer button it clears the timerHandle then re-sets it again. Once it's fired, the game ends.

<script type="text/javascript">
    var timerHandle = setTimeout("alert('Hello')",3000);
    function resetTimer() {
        window.clearTimeout(timerHandle);
        timerHandle = setTimeout("alert('Hello')",3000);
    }
</script>

<body>
    <button onclick="resetTimer()">Reset Timer</button>
</body>

1.Install-Package Microsoft.AspNet.WebApi.Cors

2 . Add this code in WebApiConfig.cs.

public static void Register(HttpConfiguration config)
{
    // Web API configuration and services

    // Web API routes

    config.EnableCors();

    config.MapHttpAttributeRoutes();

    config.Routes.MapHttpRoute(
        name: "DefaultApi",
        routeTemplate: "api/{controller}/{id}",
        defaults: new { id = RouteParameter.Optional }
    );
}

3. Add this

using System.Web.Http.Cors; 

4. Add this code in Api Controller (HomeController.cs)

[EnableCors(origins: "*", headers: "*", methods: "*")]
public class HomeController : ApiController
{
    [HttpGet]
    [Route("api/Home/test")]
    public string test()
    {
       return "";
    }
}

In theory, the diamond operator allows you to write more compact (and readable) code by saving repeated type arguments. In practice, it's just two confusing chars more giving you nothing. Why?

1. No sane programmer uses raw types in new code. So the compiler could simply assume that by writing no type arguments you want it to infer them.
2. The diamond operator provides no type information, it just says the compiler, "it'll be fine". So by omitting it you can do no harm. At any place where the diamond operator is legal it could be "inferred" by the compiler.

IMHO, having a clear and simple way to mark a source as Java 7 would be more useful than inventing such strange things. In so marked code raw types could be forbidden without losing anything.

Btw., I don't think that it should be done using a compile switch. The Java version of a program file is an attribute of the file, no option at all. Using something as trivial as

package 7 com.example;

could make it clear (you may prefer something more sophisticated including one or more fancy keywords). It would even allow to compile sources written for different Java versions together without any problems. It would allow introducing new keywords (e.g., "module") or dropping some obsolete features (multiple non-public non-nested classes in a single file or whatsoever) without losing any compatibility.

This is probably the longest process to make a singleton in typescript, but in larger applications is the one that has worked better for me.

First you need a Singleton class in, let's say, "./utils/Singleton.ts":

module utils {
    export class Singleton {
        private _initialized: boolean;

        private _setSingleton(): void {
            if (this._initialized) throw Error('Singleton is already initialized.');
            this._initialized = true;
        }

        get setSingleton() { return this._setSingleton; }
    }
}

Now imagine you need a Router singleton "./navigation/Router.ts":

/// <reference path="../utils/Singleton.ts" />

module navigation {
    class RouterClass extends utils.Singleton {
        // NOTICE RouterClass extends from utils.Singleton
        // and that it isn't exportable.

        private _init(): void {
            // This method will be your "construtor" now,
            // to avoid double initialization, don't forget
            // the parent class setSingleton method!.
            this.setSingleton();

            // Initialization stuff.
        }

        // Expose _init method.
        get init { return this.init; }
    }

    // THIS IS IT!! Export a new RouterClass, that no
    // one can instantiate ever again!.
    export var Router: RouterClass = new RouterClass();
}

Nice!, now initialize or import wherever you need:

/// <reference path="./navigation/Router.ts" />

import router = navigation.Router;

router.init();
router.init(); // Throws error!.

The nice thing about doing singletons this way is that you still use all the beauty of typescript classes, it gives you nice intellisense, the singleton logic keeps someway separated and it's easy to remove if needed.

You can search "slashdot effect analysis" for graphs of what you would see if some aspect of the site suddenly became popular in the news, e.g. this graph on wiki.

Web-applications that survive tend to be the ones which can generate static pages instead of putting every request through a processing language.

There was an excellent video (I think it might have been on ted.com? I think it might have been by flickr web team? Does someone know the link?) with ideas on how to scale websites beyond the single server, e.g. how to allocate connections amongst the mix of read-only and read-write servers to get best effect for various types of users.

This is an answer to the comment posted by erikkallen:

You don't need a temp table. If you only have a few rows, (SELECT 1 FROM dual UNION SELECT 2 FROM dual) will do. Why would your example give ORA-0001? Wouldn't merge take the update lock on the index key and not continue until Sess1 has either committed or rolled back? – erikkallen

Well, try it yourself and tell me whether you get the same error or not:

SESS1:

create table t1 (pk int primary key, i int);
create table t11 (pk int primary key, i int);
insert into t1 values(1, 1);
insert into t11 values(2, 21);
insert into t11 values(3, 31);
commit;

SESS2: insert into t1 values(2, 2);

SESS1:

MERGE INTO t1 d
USING t11 s ON (d.pk = s.pk)
WHEN NOT MATCHED THEN INSERT (d.pk, d.i) VALUES (s.pk, s.i);

SESS2: commit;

SESS1: ORA-00001

For MacOS

1. Open terminal

2. Run the below code and hit enter

    sudo kill $(sudo lsof -t -i:4200)
   

kubectl delete po,ing,svc,pv,pvc,sc,ep,rc,deploy,replicaset,daemonset --all -A

If your values are coming from the database, show selected values in that way.

<div class="form-group">
    <label for="status">Status</label>
    <select class="form-control" name="status" [(ngModel)]="category.status">
       <option [value]="1" [selected]="category.status ==1">Active</option>
       <option [value]="0" [selected]="category.status ==0">In Active</option>
    </select>
</div>

Make sure to balance the risk that fresh statistics cause undesirable changes to query plans against the risk that stale statistics can themselves cause query plans to change.

Imagine you have a bug database with a table ISSUE and a column CREATE_DATE where the values in the column increase more or less monotonically. Now, assume that there is a histogram on this column that tells Oracle that the values for this column are uniformly distributed between January 1, 2008 and September 17, 2008. This makes it possible for the optimizer to reasonably estimate the number of rows that would be returned if you were looking for all issues created last week (i.e. September 7 - 13). If the application continues to be used and the statistics are never updated, though, this histogram will be less and less accurate. So the optimizer will expect queries for "issues created last week" to be less and less accurate over time and may eventually cause Oracle to change the query plan negatively.

HTML are markup languages, basically they are set of tags like <html>, <body>, which is used to present a website using css, and javascript as a whole. All these, happen in the clients system or the user you will be browsing the website.

Now, Connecting to a database, happens on whole another level. It happens on server, which is where the website is hosted.

So, in order to connect to the database and perform various data related actions, you have to use server-side scripts, like php, jsp, asp.net etc.

Now, lets see a snippet of connection using MYSQLi Extension of PHP

$db = mysqli_connect('hostname','username','password','databasename');

This single line code, is enough to get you started, you can mix such code, combined with HTML tags to create a HTML page, which is show data based pages. For example:

<?php
    $db = mysqli_connect('hostname','username','password','databasename');
?>
<html>
    <body>
          <?php
                $query = "SELECT * FROM `mytable`;";
                $result = mysqli_query($db, $query);
                while($row = mysqli_fetch_assoc($result)) {
                      // Display your datas on the page
                }
          ?>
    </body>
</html>

In order to insert new data into the database, you can use phpMyAdmin or write a INSERT query and execute them.

Example: to view the Windows User Name on Cell C5, you can use this script :

Range("C5").Value = ": " & Environ("USERNAME").

Keyboard(BT) commands can be passed through command prompt

open command prompt and write "adb shell input keyevent keycode"

examples:-

for "enter" write
adb shell input keyevent 23

up
adb shell input keyevent 19

down
adb shell input keyevent 20

left
adb shell input keyevent 21

right
adb shell input keyevent 22

You need to call self.a() to invoke a from b. a is not a global function, it is a method on the class.

You may want to read through the Python tutorial on classes some more to get the finer details down.

desired o/p: Enabling feature XYZ......Done

you can use below command

$a = "Enabling feature XYZ"

Write-output "$a......Done"

you have to add variable and statement inside quotes. hope this is helpful :)

Have You tried BeautifulSoup ?

from bs4 import BeautifulSoup
soup = BeautifulSoup('<div id="remository">20</div>')
tag=soup.div
print(tag.string)

This gives You 20 on output.

If you have ListView in any Parent panel (ListView dock fill), you can use simply method...

private void ListViewHeaderWidth() {
        int HeaderWidth = (listViewInfo.Parent.Width - 2) / listViewInfo.Columns.Count;
        foreach (ColumnHeader header in listViewInfo.Columns)
        {
            header.Width = HeaderWidth;
        }
    }

import csv
count = 0
with open('filename.csv', 'rb') as count_file:
    csv_reader = csv.reader(count_file)
    for row in csv_reader:
        count += 1

print count

You can't do this no. There is one attribute selector that matches exactly or partial until a - sign, but it wouldn't work here because you have multiple attributes. If the class name you are looking for would always be first, you could do this:

<html>
<head>
<title>Test Page</title>
<style type="text/css">
div[class|=status] { background-color:red; }
</style>
</head>
<body>
<div id='A' class='status-important bar-class'>A</div>
<div id='B' class='bar-class'>B</div>
<div id='C' class='status-low-priority bar-class'>C</div>

</body>
</html>

Note that this is just to point out which CSS attribute selector is the closest, it is not recommended to assume class names will always be in front since javascript could manipulate the attribute.

Another solution of max using reduce:

[1,2,5,0,4].reduce((a,b,i) => a[0] < b ? [b,i] : a, [Number.MIN_VALUE,-1])
//[5,2]

This returns [5e-324, -1] if the array is empty. If you want just the index, put [1] after.

Min via (Change to > and MAX_VALUE):

[1,2,5,0,4].reduce((a,b,i) => a[0] > b ? [b,i] : a, [Number.MAX_VALUE,-1])
//[0, 3]

I set cookies in React using the react-cookie library, it has options you can pass in options to set expiration time.

Check it out here

An example of its use for your case:

import cookie from "react-cookie";

setCookie() => {
  let d = new Date();
  d.setTime(d.getTime() + (minutes*60*1000));

  cookie.set("onboarded", true, {path: "/", expires: d});
};

I don't think it is possible to share a database link between more than one user but not all. They are either private (for one user only) or public (for all users).

A good way around this is to create a view in SCHEMA_B that exposes the table you want to access through the database link. This will also give you good control over who is allowed to select from the database link, as you can control the access to the view.

Do like this:

create database link db_link... as before;
create view mytable_view as select * from mytable@db_link;
grant select on mytable_view to myuser;

A simple git fetch/pull command will throw a authentication failed message. But do the same git fetch/pull command second time, and it should prompt a window asking for credential(username/password). Enter your Id and new password and it should save and move on.

If you want a report includes the commands -vstats_file MFRfile.txt into the presets like the example. this can make a report which it's ubicadet in the folder source of your file Source. you can put any name if you want , i solved my problem "i write many times in this forum" reading a complete .docx about mpeg properties. finally i can do my progress bar reading this txt file generated.

Regards.

1. In Notepad++ go to Plugins > Plugin manager > Show Plugin Manager then find Xml Tools plugin. Tick the box and click Install

   

2. Open XML document you want to validate and click Ctrl+Shift+Alt+M (Or use Menu if this is your preference Plugins > XML Tools > Validate Now).
   Following dialog will open:

3. Click on .... Point to XSD file and I am pretty sure you'll be able to handle things from here.

Hope this saves you some time.

EDIT: Plugin manager was not included in some versions of Notepad++ because many users didn't like commercials that it used to show. If you want to keep an older version, however still want plugin manager, you can get it on github, and install it by extracting the archive and copying contents to plugins and updates folder.
In version 7.7.1 plugin manager is back under a different guise... Plugin Admin so now you can simply update notepad++ and have it back.

This is the most flexible/reusable way to reset all select boxes in your form.

      var $form = $('form') // Replace with your form selector
      $('select', $form).each(function() {
        $(this).val($(this).prop('defaultSelected'));
      });

Try setting the HOME environment variable in Windows to your home folder (c:\users\username).

( you can confirm that this is the problem by doing echo $HOME in git bash and echo %HOME% in cmd - latter might not be available )

from the sourcecode at http://mozilla.github.com/pdf.js/build/pdf.js

/**
 * This is the main entry point for loading a PDF and interacting with it.
 * NOTE: If a URL is used to fetch the PDF data a standard XMLHttpRequest(XHR)
 * is used, which means it must follow the same origin rules that any XHR does
 * e.g. No cross domain requests without CORS.
 *
 * @param {string|TypedAray|object} source Can be an url to where a PDF is
 * located, a typed array (Uint8Array) already populated with data or
 * and parameter object with the following possible fields:
 *  - url   - The URL of the PDF.
 *  - data  - A typed array with PDF data.
 *  - httpHeaders - Basic authentication headers.
 *  - password - For decrypting password-protected PDFs.
 *
 * @return {Promise} A promise that is resolved with {PDFDocumentProxy} object.
 */

So a standard XMLHttpRequest(XHR) is used for retrieving the document. The Problem with this is that XMLHttpRequests do not support data: uris (eg. data:application/pdf;base64,JVBERi0xLjUK...).

But there is the possibility of passing a typed Javascript Array to the function. The only thing you need to do is to convert the base64 string to a Uint8Array. You can use this function found at https://gist.github.com/1032746

var BASE64_MARKER = ';base64,';

function convertDataURIToBinary(dataURI) {
  var base64Index = dataURI.indexOf(BASE64_MARKER) + BASE64_MARKER.length;
  var base64 = dataURI.substring(base64Index);
  var raw = window.atob(base64);
  var rawLength = raw.length;
  var array = new Uint8Array(new ArrayBuffer(rawLength));

  for(var i = 0; i < rawLength; i++) {
    array[i] = raw.charCodeAt(i);
  }
  return array;
}

tl;dr

var pdfAsDataUri = "data:application/pdf;base64,JVBERi0xLjUK..."; // shortened
var pdfAsArray = convertDataURIToBinary(pdfAsDataUri);
PDFJS.getDocument(pdfAsArray)

You can specify the color option as a list directly to the plot function.

from matplotlib import pyplot as plt
from itertools import cycle, islice
import pandas, numpy as np  # I find np.random.randint to be better

# Make the data
x = [{i:np.random.randint(1,5)} for i in range(10)]
df = pandas.DataFrame(x)

# Make a list by cycling through the colors you care about
# to match the length of your data.
my_colors = list(islice(cycle(['b', 'r', 'g', 'y', 'k']), None, len(df)))

# Specify this list of colors as the `color` option to `plot`.
df.plot(kind='bar', stacked=True, color=my_colors)

To define your own custom list, you can do a few of the following, or just look up the Matplotlib techniques for defining a color item by its RGB values, etc. You can get as complicated as you want with this.

my_colors = ['g', 'b']*5 # <-- this concatenates the list to itself 5 times.
my_colors = [(0.5,0.4,0.5), (0.75, 0.75, 0.25)]*5 # <-- make two custom RGBs and repeat/alternate them over all the bar elements.
my_colors = [(x/10.0, x/20.0, 0.75) for x in range(len(df))] # <-- Quick gradient example along the Red/Green dimensions.

The last example yields the follow simple gradient of colors for me:

I didn't play with it long enough to figure out how to force the legend to pick up the defined colors, but I'm sure you can do it.

In general, though, a big piece of advice is to just use the functions from Matplotlib directly. Calling them from Pandas is OK, but I find you get better options and performance calling them straight from Matplotlib.

I was getting the same problem while I trying to create a new app. If you write python manage.py startapp myapp, then it looks for usr/bin/python. But you need this "python" which is located in /bin directory of your virtual env path. I solved this by mentioning the virtualenv's python path just like this:

<env path>/bin/python manage.py startapp myapp

Basically, pip comes with python itself.Therefore it carries no meaning for using pip itself to install or upgrade python. Thus,try to install python through installer itself,visit the site "https://www.python.org/downloads/" for more help. Thank you.

Needing a more generic object comparison function than had been posted, I cooked up the following. Critique appreciated...

Object.prototype.equals = function(iObj) {
  if (this.constructor !== iObj.constructor)
    return false;
  var aMemberCount = 0;
  for (var a in this) {
    if (!this.hasOwnProperty(a))
      continue;
    if (typeof this[a] === 'object' && typeof iObj[a] === 'object' ? !this[a].equals(iObj[a]) : this[a] !== iObj[a])
      return false;
    ++aMemberCount;
  }
  for (var a in iObj)
    if (iObj.hasOwnProperty(a))
      --aMemberCount;
  return aMemberCount ? false : true;
}

use [\\W+] or "[^a-zA-Z0-9]" as regex to match any special characters and also use String.replaceAll(regex, String) to replace the spl charecter with an empty string. remember as the first arg of String.replaceAll is a regex you have to escape it with a backslash to treat em as a literal charcter.

          String c= "hjdg$h&jk8^i0ssh6";
        Pattern pt = Pattern.compile("[^a-zA-Z0-9]");
        Matcher match= pt.matcher(c);
        while(match.find())
        {
            String s= match.group();
        c=c.replaceAll("\\"+s, "");
        }
        System.out.println(c);

I was having trouble with mobile touchscreen button styling. This will fix your hover-stick / active button problems.

body, html {
  width: 600px;
}
p {
  font-size: 20px;
}

button {
  border: none;
  width: 200px;
  height: 60px;
  border-radius: 30px;
  background: #00aeff;
  font-size: 20px;
}

button:active {
  background: black;
  color: white;
}

.delayed {
  transition: all 0.2s;
  transition-delay: 300ms;
}

.delayed:active {
  transition: none;
}

<h1>Sticky styles for better touch screen buttons!</h1>

<button>Normal button</button>

<button class="delayed"><a href="https://www.google.com"/>Delayed style</a></button>

<p>The CSS :active psuedo style is displayed between the time when a user touches down (when finger contacts screen) on a element to the time when the touch up (when finger leaves the screen) occures.   With a typical touch-screen tap interaction, the time of which the :active psuedo style is displayed can be very small resulting in the :active state not showing or being missed by the user entirely.  This can cause issues with users not undertanding if their button presses have actually reigstered or not.</p>

<p>Having the the :active styling stick around for a few hundred more milliseconds after touch up would would improve user understanding when they have interacted with a button.</p>

I would strongly suggest you start using jQuery. Your code would look like:

$(function() {
    $('form[name="myform"]').submit(function(e) {
        var username = $('form[name="myform"] input[name="username"]').val();
        if ( username == '') {
            e.preventDefault();
            $('#errors').text('*Please enter a username*');
        }
    });
});

Short version: it's marking that hash as attached to the current package namespace (so that that package provides its class implementation).

Here is another method using .loc to replace inf with nan on a Series:

s.loc[(~np.isfinite(s)) & s.notnull()] = np.nan

So, in response to the original question:

df = pd.DataFrame(np.ones((3, 3)), columns=list('ABC'))

for i in range(3): 
    df.iat[i, i] = np.inf

df
          A         B         C
0       inf  1.000000  1.000000
1  1.000000       inf  1.000000
2  1.000000  1.000000       inf

df.sum()
A    inf
B    inf
C    inf
dtype: float64

df.apply(lambda s: s[np.isfinite(s)].dropna()).sum()
A    2
B    2
C    2
dtype: float64

That's because itoa isn't a standard function. Try snprintf instead.

char str[LEN];
snprintf(str, LEN, "%d", 42);

In case you have a form you can add a class name as such:

<form id="my-form">
  <input class="js-input" type="text" name="samplename" />
  <input class="js-input" type="text" name="samplename" />
  <input class="submit" type="submit" value="Submit" />
</form>

you can then use the addClassRules method of validator to add your rules like this and this will apply to all the dynamically added inputs:

$(document).ready(function() {
  $.validator.addClassRules('js-input', {
    required: true,
  });
  //validate the form
  $('#my-form').validate();
});

I have used sub-query and it worked great!

SELECT *,(SELECT count(*) FROM $this->tbl_news WHERE
$this->tbl_news.cat_id=$this->tbl_categories.cat_id) as total_news FROM
$this->tbl_categories

    new KeyValuePair<string, int>("D", 2),
    new KeyValuePair<string, int>("E", 8),
};

int input = 11;
var items = SubSets(list).FirstOrDefault(x => x.Sum(y => y.Value)==input);

                    {
                        l.Add(list[j]);
                    }
                }

                yield return l;
            }
        }
    }
}

so not sure if this answers your question but the indexOf the items you are adding keep returning -1. Not to familiar with js but it appears the items do that because they are not in the array yet. I made a jsfiddle of a little modified code for you.

this.items = [];

add(1);
add(2);
add(3);

document.write("added items to array");
document.write("<br>");
function  add(item) {
        //document.write(this.items.indexOf(item));
    if(this.items.indexOf(item) <= -1) {

      this.items.push(item);
      //document.write("Hello World!");
    }
}

document.write("array is : " + this.items);

This just means that the git clone copied the files down from github and placed them into a folder. If you try to do it again it will not let you because it can't clone into a folder that has files into it. So if you think the git clone did not complete properly, just delete the folder and do the git clone again. The clone creates a folder the same name as the git repo.

This ORA-01461 does not occur only while inserting into a Long column. This error can occur when binding a long string for insert into a VARCHAR2 column and most commonly occurs when there is a multi byte(means single char can take more than one byte space in oracle) character conversion issue.

If the database is UTF-8 then, because of the fact that each character can take up to 3 bytes, conversion of 3 applied to check and so actually limited to use 1333 characters to insert into varchar2(4000).

Another solution would be change the datatype from varchar2(4000) to CLOB.

The getDate method of datepicker returns a date type, not a string.

You need to format the returned value to a string using your date format. Use datepicker's formatDate function:

var dateTypeVar = $('#datepicker').datepicker('getDate');
$.datepicker.formatDate('dd-mm-yy', dateTypeVar);

The full list of format specifiers is available here.

From all I have read you cannot do exactly what you want without javascript. If you float left before text

<div style="float:left;">widget</div> here is some CONTENT, etc.

Your content wraps as expected. But your widget is in the top left. If you instead put the float after the content

here is some CONTENT, etc. <div style="float:left;">widget</div>

Then your content will wrap the last line to the right of the widget if the last line of content can fit to the right of the widget, otherwise no wrapping is done. To make borders and backgrounds actually include the floated area in the previous example, most people add:

here is some CONTENT, etc. <div style="float:left;">widget</div><div style="clear:both;"></div>

In your question you are using bootstrap which just adds row-fluid::after { content: ""} which resolves the border/background issue.

Moving your content up will give you the one line wrap : http://jsfiddle.net/jJNPY/34/

  <div class="container-fluid">
  <div class="row-fluid">
    <div class="offset1 span8 pull-right">
    ... Widget 1...
    </div>
    .... a lot of content ....
    <div class="span8" style="margin-left: 0;">
    ... Widget 2...
    </div>


  </div>

in accord with Laravel documentation, I create in app/Http/Controllers/Auth/LoginController.php the following method :

protected function redirectTo()

    $user=Auth::user();

    if($user->account_type == 1){

    }else{
        return '/home';
    }

}

to get the user information from my db I used "Illuminate\Support\Facades\Auth;".

It is very simple just look at their names @RequestParam it consist of two parts one is "Request" which means it is going to deal with request and other part is "Param" which itself makes sense it is going to map only the parameters of requests to java objects. Same is the case with @RequestBody it is going to deal with the data that has been arrived with request like if client has send json object or xml with request at that time @requestbody must be used.

Both of the above two answers work for me with a similar problem.

However, the body {-webkit-transform} approach causes all elements on the page to effectively be rendered in 3D. This isn't the worst thing, but it slightly changes the rendering of text and other CSS-styled elements.

It may be an effect you want. It may be useful if you're doing a lot of transform on your page. Otherwise, -webkit-backface-visibility:hidden on the element your transforming is the least invasive option.

In Java version prior to 1.7 you cannot cast object to primitive type

double d = (double) obj;

You can cast an Object to a Double just fine

Double d = (Double) obj;

Beware, it can throw a ClassCastException if your object isn't a Double

Here is a reference for using EXPLAIN PLAN with Oracle: http://download.oracle.com/docs/cd/B19306_01/server.102/b14211/ex_plan.htm), with specific information about the columns found here: http://download.oracle.com/docs/cd/B19306_01/server.102/b14211/ex_plan.htm#i18300

Your mention of 'FULL' indicates to me that the query is doing a full-table scan to find your data. This is okay, in certain situations, otherwise an indicator of poor indexing / query writing.

Generally, with explain plans, you want to ensure your query is utilizing keys, thus Oracle can find the data you're looking for with accessing the least number of rows possible. Ultimately, you can sometime only get so far with the architecture of your tables. If the costs remain too high, you may have to think about adjusting the layout of your schema to be more performance based.

I believe it is possible to get 'best of both worlds' using closures inside constructors. There are two variations:

All data members are private

function myFunc() {_x000D_
   console.log('Value of x: ' + this.x);_x000D_
   this.myPrivateFunc();_x000D_
}_x000D_
_x000D_
function myPrivateFunc() {_x000D_
   console.log('Enhanced value of x: ' + (this.x + 1));_x000D_
}_x000D_
_x000D_
class Test {_x000D_
   constructor() {_x000D_
_x000D_
      let internal = {_x000D_
         x : 2,_x000D_
      };_x000D_
      _x000D_
      internal.myPrivateFunc = myPrivateFunc.bind(internal);_x000D_
      _x000D_
      this.myFunc = myFunc.bind(internal);_x000D_
   }_x000D_
};

Some members are private

NOTE: This is admittedly ugly. If you know a better solution, please edit this response.

function myFunc(priv, pub) {_x000D_
   pub.y = 3; // The Test object now gets a member 'y' with value 3._x000D_
   console.log('Value of x: ' + priv.x);_x000D_
   this.myPrivateFunc();_x000D_
}_x000D_
_x000D_
function myPrivateFunc() {_x000D_
   pub.z = 5; // The Test object now gets a member 'z' with value 3._x000D_
   console.log('Enhanced value of x: ' + (priv.x + 1));_x000D_
}_x000D_
_x000D_

      _x000D_

      this.myFunc = myFunc.bind(null, internal, self);_x000D_
   }_x000D_
};

If you want to use jQuery, the .load() function is the correct function you are after;

But you are missing the # from the div1 id selector in the example 2)

This should work:

$("#div1").load("file2.html");

Add extra columns as null for the table having less columns like

Select Col1, Col2, Col3, Col4, Col5 from Table1
Union
Select Col1, Col2, Col3, Null as Col4, Null as Col5 from Table2

using PhpMyAdmin version 4.5.4.1deb2ubuntu2, you can set the variables in /etc/phpmyadmin/config-db.php

so set $dbserver to your server name, e.g. $dbserver='mysql.example.com';

<?php
##
## database access settings in php format
## automatically generated from /etc/dbconfig-common/phpmyadmin.conf
## by /usr/sbin/dbconfig-generate-include
##
## by default this file is managed via ucf, so you shouldn't have to
## worry about manual changes being silently discarded.  *however*,
## you'll probably also want to edit the configuration file mentioned
## above too.
##
$dbuser='phpmyadmin';
$dbpass='P@55w0rd';
$basepath='';
$dbname='phpmyadmin';
$dbserver='localhost';
$dbport='';
$dbtype='mysql';

Best way of doing it

Below code is to copy the visible data in DBExtract sheet, and paste it into duplicateRecords sheet, with only filtered values. Range selected by me is the maximum range that can be occupied by my data. You can change it as per your need.

  Sub selectVisibleRange()

    Dim DbExtract, DuplicateRecords As Worksheet
    Set DbExtract = ThisWorkbook.Sheets("Export Worksheet")
    Set DuplicateRecords = ThisWorkbook.Sheets("DuplicateRecords")

    DbExtract.Range("A1:BF9999").SpecialCells(xlCellTypeVisible).Copy
    DuplicateRecords.Cells(1, 1).PasteSpecial


    End Sub

For me it was a case of having my Groovy hat on instead of the Python 3 one.

Forgot the return keyword at the end of a def function.

Had not been coding Python 3 in earnest for a couple of months. Was thinking last statement evaluated in routine was being returned per the Groovy (or Rust) way.

Took a few iterations, looking at the stack trace, inserting try: ... except TypeError: ... block debugging/stepping thru code to figure out what was wrong.

The solution for the message certainly did not make the error jump out at me.

You can just use numpy arrays. Look at the numpy for matlab users page for a detailed overview of the pros and cons of arrays w.r.t. matrices.

As I mentioned in the comment, having to use the dot() function or method for mutiplication of vectors is the biggest pitfall. But then again, numpy arrays are consistent. All operations are element-wise. So adding or subtracting arrays and multiplication with a scalar all work as expected of vectors.

Edit2: Starting with Python 3.5 and numpy 1.10 you can use the @ infix-operator for matrix multiplication, thanks to pep 465.

Edit: Regarding your comment:

1. Yes. The whole of numpy is based on arrays.

2. Yes. linalg.norm(v) is a good way to get the length of a vector. But what you get depends on the possible second argument to norm! Read the docs.

3. To normalize a vector, just divide it by the length you calculated in (2). Division of arrays by a scalar is also element-wise.

   An example in ipython:

   In [1]: import math
   
   In [2]: import numpy as np
   
   In [3]: a = np.array([4,2,7])
   
   In [4]: np.linalg.norm(a)
   Out[4]: 8.3066238629180749
   
   In [5]: math.sqrt(sum([n**2 for n in a]))
   Out[5]: 8.306623862918075
   
   In [6]: b = a/np.linalg.norm(a)
   
   In [7]: np.linalg.norm(b)
   Out[7]: 1.0
   

   Note that In [5] is an alternative way to calculate the length. In [6] shows normalizing the vector.

select m.definition from sys.all_sql_modules m inner join  sys.triggers t
on m.object_id = t.object_id 

Here just copy the definition and alter the trigger.

Else you can just goto SSMS and Expand the your DB and under Programmability expand Database Triggeres then right click on the specific trigger and click modify there also you can change.

I have found this link

I have no idea why this works but I tried many work arounds and this is the only one that worked for me. In short, run the three commands below:

git fsck --full
git reflog expire --expire=now --all
git gc --prune=now

Length of characters to be matched.

{n,m}  n <= length <= m
{n}    length == n
{n,}   length >= n

And by default, the engine is greedy to match this pattern. For example, if the input is 123456789, \d{2,5} will match 12345 which is with length 5.

If you want the engine returns when length of 2 matched, use \d{2,5}?

Tell PDO your charset initially.... something like

PDO("mysql:host=$host;dbname=$DB_name;charset=utf8;", $username, $password);

Notice the: charset=utf8; part.

hope it helps!

when I use MVC5, and add the claim here.

public async Task<ClaimsIdentity> GenerateUserIdentityAsync(PATAUserManager manager)
    {
        // Note the authenticationType must match the one defined in CookieAuthenticationOptions.AuthenticationType
        var userIdentity = await manager.CreateIdentityAsync(this, DefaultAuthenticationTypes.ApplicationCookie);
        // Add custom user claims here
        userIdentity.AddClaim(new Claim(ClaimTypes.Role, this.Role));

        return userIdentity;
    }

when I'm check the claim result in the SignInAsync function,i can't get the role value use anyway. But...

after this request finished, I can access Role in other action(anther request).

 var userWithClaims = (ClaimsPrincipal)User;
        Claim CRole = userWithClaims.Claims.First(c => c.Type == ClaimTypes.Role);

so, i think maybe asynchronous cause the IEnumerable updated behind the process.

There are a few operations you can only do with DI/SI (or their extended counterparts, if you didn't learn ASM in 1985). Among these are

REP STOSB
REP MOVSB
REP SCASB

Which are, respectively, operations for repeated (= mass) storing, loading and scanning. What you do is you set up SI and/or DI to point at one or both operands, perhaps put a count in CX and then let 'er rip. These are operations that work on a bunch of bytes at a time, and they kind of put the CPU in automatic. Because you're not explicitly coding loops, they do their thing more efficiently (usually) than a hand-coded loop.

Just in case you're wondering: Depending on how you set the operation up, repeated storing can be something simple like punching the value 0 into a large contiguous block of memory; MOVSB is used, I think, to copy data from one buffer (well, any bunch of bytes) to another; and SCASB is used to look for a byte that matches some search criterion (I'm not sure if it's only searching on equality, or what – you can look it up :) )

That's most of what those regs are for.

Also if you want selected field from table and aggregated then as array .

SELECT json_agg(json_build_object('data_a',a,
                                  'data_b',b,
))  from t;

The result will come .

 [{'data_a':1,'data_b':'value1'}
  {'data_a':2,'data_b':'value2'}]

To show the "My Location" button you have to call

map.getUiSettings().setMyLocationButtonEnabled(true);

on your GoogleMap object.
