You can do a side-by-side diff using sdiff as follows:

$ git difftool -y -x sdiff  HEAD^ | less

where HEAD^ is an example that you should replace with whatever you want to diff against.

I found this solution here where there are a couple of other suggestions also. However, this one answer's the OP's question succinctly and clearly.

See the man git-difftool for an explanation of the arguments.

Taking the comments on board, you can create a handy git sdiff command by writing the following executable script:

#!/bin/sh
git difftool -y -x "sdiff -w $(tput cols)" "${@}" | less

Save it as /usr/bin/git-sdiff and chmod +x it. Then you'll be able to do this:

$ git sdiff HEAD^

Extra Tip

As suggested in comments you can use icdiff to do what sdiff does with colored output:

$ more /usr/bin/git-sdiff
#!/bin/sh
git difftool -y -x "icdiff --cols=$(tput cols)" "${@}" | less

Simply use help(package="my_package") and look at the version shown.

This assumes there are no other package versions in the same .libPaths.

I newer version of xampp you may use another method first open your httpd-xampp.conf file and find the string "phpmyadmin" using ctrl+F command (Windows). and then replace this code

Alias /phpmyadmin "D:/server/phpMyAdmin/"
<Directory "D:/server/phpMyAdmin">
    AllowOverride AuthConfig
    Require local
    ErrorDocument 403 /error/XAMPP_FORBIDDEN.html.var
</Directory>

with this

Alias /phpmyadmin "D:/server/phpMyAdmin/"
<Directory "D:/server/phpMyAdmin">
    AllowOverride AuthConfig
    Require all granted
    ErrorDocument 403 /error/XAMPP_FORBIDDEN.html.var
</Directory>

Don't Forget to Restart your Xampp.

For Bootstrap 3.

I also got the same issue and not able to create a jar, and I found that in Windows-->Prefernces-->Java-->installed JREs By default JRE was added to the build path of newly created java project so just changed it to your prefered JDK.

for me encoding with utf16 worked

file = open('filename.csv', encoding="utf16")

If you don't need in a complete reference to the most part of algorithms and data structures that are in use and just want to get acquainted with common techniques I would recommend something more lightweight than Cormen, Sedgewick or Knuth. I think, Algorithms and Data Structures by N. Wirth is not as bad choice even in spite of it was printed far ago.

Accessing CSS property & manipulating is quite easy using .css(). For example, to change single property:

$("selector").css('top', '50px');

Build up a JavaScript data structure with the required information, then turn it into the json string at the end.

Based on what I think you're doing, try something like this:

var result = [];
for (var name in goals) {
  if (goals.hasOwnProperty(name)) {
    result.push({name: name, goals: goals[name]});
  }
}

res.contentType('application/json');
res.send(JSON.stringify(result));

or something along those lines.

var animals = new List<string> { "bird", "dog" };
List<string> animals= new List<string> { "bird", "dog" };

Above two are the shortest ways, please see https://www.dotnetperls.com/list

Leaving an answer for anyone looking to do something similar but in a horizontal direction, like I wanted to.

Tweaking @strider820's answer like below will do the magic:

.fixed-content {        //comments showing what I replaced.
    left:0;             //top: 0;
    right:0;            //bottom:0;
    position:fixed;
    overflow-y:hidden;  //overflow-y:scroll;
    overflow-x:auto;    //overflow-x:hidden;
}

That's it. Also check this comment where @train explained using overflow:auto over overflow:scroll.

What does const mean
First, realize that the semantics of a "const" keyword means different things to different people:

• read-only reference - Java final semantics - reference variable itself cannot be reassigned to point to another instance (memory location), but the instance itself is modifiable
• readable-only reference - C const pointer/reference semantics - means this reference cannot be used to modify the instance (e.g. cannot assign to instance variables, cannot invoke mutable methods) - affects the reference variable only, so a non-const reference pointing to the same instance could modify the instance
• immutable object - means the instance itself cannot be modified - applies to instance, so any non-const reference would not be allowed or could not be used to modify the instance
• some combination of the the above?
• others?

Why or Why Not const
Second, if you really want to dig into some of the "pro" vs "con" arguments, see the discussion under this request for enhancement (RFE) "bug". This RFE requests a "readable-only reference"-type "const" feature. Opened in 1999 and then closed/rejected by Sun in 2005, the "const" topic was vigorously debated:

http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4211070

While there are a lot of good arguments on both sides, some of the oft-cited (but not necessarily compelling or clear-cut) reasons against const include:

• may have confusing semantics that may be misused and/or abused (see the What does const mean above)
• may duplicate capability otherwise available (e.g. designing an immutable class, using an immutable interface)
• may be feature creep, leading to a need for other semantic changes such as support for passing objects by value

Before anyone tries to debate me about whether these are good or bad reasons, note that these are not my reasons. They are simply the "gist" of some of the reasons I gleaned from skimming the RFE discussion. I don't necessarily agree with them myself - I'm simply trying to cite why some people (not me) may feel a const keyword may not be a good idea. Personally, I'd love more "const" semantics to be introduced to the language in an unambiguous manner.

As drewm himself said this is due to the subsequent redirect after the POST to the script has in fact succeeded. (I might have added this as a comment to his answer but you need 50 reputation to comment and I'm new round here - daft rule IMHO)

BUT it also applies if you're trying to redirect to a page, not just a directory - at least it did for me. I was trying to redirect to /thankyou.html. What fixes this is using an absolute URL, i.e. http://example.com/thankyou.html

I had the same issue when I clone my project from Git and directly build the solution first time. Instead of that go to the local repository in file explorer and double click the solution file (.sln) solved my issue.

git remote prune origin prunes tracking branches not on the remote.

git branch --merged lists branches that have been merged into the current branch.

xargs git branch -d deletes branches listed on standard input.

Be careful deleting branches listed by git branch --merged. The list could include master or other branches you'd prefer not to delete.

To give yourself the opportunity to edit the list before deleting branches, you could do the following in one line:

git branch --merged >/tmp/merged-branches && \
  vi /tmp/merged-branches && xargs git branch -d </tmp/merged-branches

Relational databases have a mathematical basis (set theory, relational theory), which are distilled into SQL == Structured Query Language.

NoSQL's many forms (e.g. document-based, graph-based, object-based, key-value store, etc.) may or may not be based on a single underpinning mathematical theory. As S. Lott has correctly pointed out, hierarchical data stores do indeed have a mathematical basis. The same might be said for graph databases.

I'm not aware of a universal query language for NoSQL databases.

You can do it with gridview's datarow bound event. try the following sample of code:

protected void grv_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.Header)
{
e.Row.Cells[0].Text = "TiTle";
}
}

For more details about the row databound event study Thsi....

No need for a regex here, if you just want to replace a piece of string by another: using str_replace() should be more than enough :

$new = str_replace(' ', '%20', $your_string);

But, if you want a bit more than that, and you probably do, if you are working with URLs, you should take a look at the urlencode() function.

Looking at the code always helps too. That is, you can actually take a look at the generated partial class (that calls LoadComponent) by doing the following:

1. Go to the Solution Explorer pane in the Visual Studio solution that you are interested in.
2. There is a button in the tool bar of the Solution Explorer titled 'Show All Files'. Toggle that button.
3. Now, expand the obj folder and then the Debug or Release folder (or whatever configuration you are building) and you will see a file titled YourClass.g.cs.

The YourClass.g.cs ... is the code for generated partial class. Again, if you open that up you can see the InitializeComponent method and how it calls LoadComponent ... and much more.

I'd do this one of two ways. Since you're setting your start and end dates in your t-sql code, i wouldn't ask for parameters in the stored proc

Option 1

Create Procedure [Test] AS
    DECLARE @StartDate varchar(10)
    DECLARE @EndDate varchar(10)
    Set @StartDate = '201620' --Define start YearWeek
    Set @EndDate  = (SELECT CAST(DATEPART(YEAR,getdate()) AS varchar(4)) + CAST(DATEPART(WEEK,getdate())-1 AS varchar(2)))

SELECT 
*
FROM
    (SELECT DISTINCT [YEAR],[WeekOfYear] FROM [dbo].[DimDate] WHERE [Year]+[WeekOfYear] BETWEEN @StartDate AND @EndDate ) dimd
    LEFT JOIN [Schema].[Table1] qad ON (qad.[Year]+qad.[Week of the Year]) = (dimd.[Year]+dimd.WeekOfYear)

Option 2

Create Procedure [Test] @StartDate varchar(10),@EndDate varchar(10) AS

SELECT 
*
FROM
    (SELECT DISTINCT [YEAR],[WeekOfYear] FROM [dbo].[DimDate] WHERE [Year]+[WeekOfYear] BETWEEN @StartDate AND @EndDate ) dimd
    LEFT JOIN [Schema].[Table1] qad ON (qad.[Year]+qad.[Week of the Year]) = (dimd.[Year]+dimd.WeekOfYear)

Then run exec test '2016-01-01','2016-01-25'

You can implement this using Java 8 lambdas.

import java.util.HashMap;
import java.util.Map;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.slf4j.event.Level;

public class LevelLogger {
    private static final Logger LOGGER = LoggerFactory.getLogger(LevelLogger.class);
    private static final Map<Level, LoggingFunction> map;

    static {
        map = new HashMap<>();
        map.put(Level.TRACE, (o) -> LOGGER.trace(o));
        map.put(Level.DEBUG, (o) -> LOGGER.debug(o));
        map.put(Level.INFO, (o) -> LOGGER.info(o));
        map.put(Level.WARN, (o) -> LOGGER.warn(o));
        map.put(Level.ERROR, (o) -> LOGGER.error(o));
    }

    public static void log(Level level, String s) {
        map.get(level).log(s);
    }

    @FunctionalInterface
    private interface LoggingFunction {
        public void log(String arg);
    }
}

There is an example class on Oracle Docs which works very much similar to the UNIX chmod. It works with java se 7+ though.

I am late, But If you are struggling through the following error and using datasource(javax.sql.DataSource):

The server time zone value 'CEST' is unrecognized or represents more than one time zone.

Set following line to get rid of the error:

MysqlDataSource dataSource = new MysqlDataSource();
dataSource.setServerTimezone("UTC");

Just add the document ready function, this way it waits until the DOM has been loaded, also by using the :visible pseudo you can write a simple show and hide function.

Sample

 $(document).ready(function(){

    $( '.expand' ).click(function() {
         if($( '.img_display_content' ).is(":visible")){
              $( '.img_display_content' ).hide();
         } else{
              $( '.img_display_content' ).show();
         }

    });
});

In case is saves someone else 3 hours... my case was a bit different. My code used DevExpress v11.1 v11.1.4.0. I had it all referenced correctly in my code. But .net memory profiler installed DevExpress v11.1 v11.1.12.0 in the GAC. In fact it wasn't the components I referenced but the ones they referenced internally that failed. Try as I might, the GAC is always checked first. It compiled and ran fine but I couldn't view the win forms designer and the stack trace was no help at all. Finally uninstalled .net memory profiler and all was restored.

#php -i | grep php.ini also will work too!

df = data.frame(cond=c(rep("x",3),rep("y",3)),rating=c(x,y))

You can get IP Genymotion Virtual Device Manager,then use the command like this

adb connect your ip

Using url.format:

var url = require('url');

This support all protocols and include port number. If you don't have a query string in your originalUrl you can use this cleaner solution:

var requrl = url.format({
    protocol: req.protocol,
    host: req.get('host'),
    pathname: req.originalUrl,
});

If you have a query string:

var urlobj = url.parse(req.originalUrl);
urlobj.protocol = req.protocol;
urlobj.host = req.get('host');
var requrl = url.format(urlobj);

This works fine for me...

   .delimitador{
        width:100%;
        margin:auto;
    }
    .contenedor{
        height:0px;
        width:100%;
        /*max-width:560px; /* Así establecemos el ancho máximo (si lo queremos) */
        padding-top:56.25%; /* Relación: 16/9 = 56.25% */
        position:relative;
    }

    iframe{
            position:absolute;
            height:100%;
            width:100%;
            top:0px;
            left:0px;
    }

and then

<div class="delimitador">
<div class="contenedor">
// youtube code 
</div>
</div>

Restarting MySQL works fine for me.

You can make an Embedded class, which contains your two keys, and then have a reference to that class as EmbeddedId in your Entity.

You would need the @EmbeddedId and @Embeddable annotations.

@Entity
public class YourEntity {
    @EmbeddedId
    private MyKey myKey;

    @Column(name = "ColumnA")
    private String columnA;

    /** Your getters and setters **/
}

@Embeddable
public class MyKey implements Serializable {

    @Column(name = "Id", nullable = false)
    private int id;

    @Column(name = "Version", nullable = false)
    private int version;

    /** getters and setters **/
}

Another way to achieve this task is to use @IdClass annotation, and place both your id in that IdClass. Now you can use normal @Id annotation on both the attributes

@Entity
@IdClass(MyKey.class)
public class YourEntity {
   @Id
   private int id;
   @Id
   private int version;

}

public class MyKey implements Serializable {
   private int id;
   private int version;
}

Eric Lippert recently had a very in-depth series of blog posts about this: "Every Binary Tree There Is" and "Every Tree There Is" (plus some more after that).

In answer to your specific question, he says:

The number of binary trees with n nodes is given by the Catalan numbers, which have many interesting properties. The nth Catalan number is determined by the formula (2n)! / (n+1)!n!, which grows exponentially.

Execute command as www-data user: docker exec -t --user www-data container bash -c "ls -la"

Yes. You can tell the OS what kind of transition you want to have for your activity.

@Override
public void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);
    getWindow().setWindowAnimations(ANIMATION);

    ...

}

Where ANIMATION is an integer referring to a built in animation in the OS.

This would work

setInterval(function(){$("#myButtonId").click();}, 1000);

//Data Table

 protected DataTable tblDynamic
        {
            get
            {
                return (DataTable)ViewState["tblDynamic"];
            }
            set
            {
                ViewState["tblDynamic"] = value;
            }
        }
//DynamicReport_GetUserType() function for getting data from DB


System.Data.DataSet ds = manage.DynamicReport_GetUserType();
                tblDynamic = ds.Tables[13];

//Add Column as "TypeName"

                tblDynamic.Columns.Add(new DataColumn("TypeName", typeof(string)));

//fill column data against ds.Tables[13]


                for (int i = 0; i < tblDynamic.Rows.Count; i++)
                {

                    if (tblDynamic.Rows[i]["Type"].ToString()=="A")
                    {
                        tblDynamic.Rows[i]["TypeName"] = "Apple";
                    }
                    if (tblDynamic.Rows[i]["Type"].ToString() == "B")
                    {
                        tblDynamic.Rows[i]["TypeName"] = "Ball";
                    }
                    if (tblDynamic.Rows[i]["Type"].ToString() == "C")
                    {
                        tblDynamic.Rows[i]["TypeName"] = "Cat";
                    }
                    if (tblDynamic.Rows[i]["Type"].ToString() == "D")
                    {
                        tblDynamic.Rows[i]["TypeName"] = "Dog;
                    }
                }

"Rounded" down as in your example. This will return a varchar value of the date.

DECLARE @date As DateTime2
SET @date = '2007-09-22 15:07:38.850'

SELECT CONVERT(VARCHAR(16), @date, 120) --2007-09-22 15:07
SELECT CONVERT(VARCHAR(13), @date, 120) --2007-09-22 15

It's simple:

array = []

will set array to be an empty list. (They're called lists in Python, by the way, not arrays)

If that doesn't work for you, edit your question to include a code sample that demonstrates your problem.

Geany has a plugin for markdown which does a fair job, giving you also a Markdown preview in the sidebar. It also runs on Linux, Mac OS X and Windows.

To use it, install geany, then install the package geany-plugin-markdown and select it from the plugin manager.

The (un)safe way to do this - if you are ok with not using option explicit - is...

Not TypeName(myObj) = "Empty"

This also handles the case if the object has not been declared. This is useful if you want to just comment out a declaration to switch off some behaviour...

Dim myObj as Object
Not TypeName(myObj) = "Empty"  '/ true, the object exists - TypeName is Object

'Dim myObj as Object
Not TypeName(myObj) = "Empty"  '/ false, the object has not been declared

This works because VBA will auto-instantiate an undeclared variable as an Empty Variant type. It eliminates the need for an auxiliary Boolean to manage the behaviour.

Just had a similar issue

Resolved it by checking in httpd.conf

     # AllowOverride controls what directives may be placed in .htaccess files.
     # It can be "All", "None", or any combination of the keywords:
     #   Options FileInfo AuthConfig Limit
     #
     AllowOverride All   <--- make sure this is not set to "None"

It is worth bearing in mind I tried (from Mark's answer) the "put garbage in the .htaccess" which did give a server error - but even though it was being read, it wasn't being acted on due to no overrides allowed.

NASA has a paper on radiation-hardened software. It describes three main tasks:

1. Regular monitoring of memory for errors then scrubbing out those errors,
2. robust error recovery mechanisms, and
3. the ability to reconfigure if something no longer works.

Note that the memory scan rate should be frequent enough that multi-bit errors rarely occur, as most ECC memory can recover from single-bit errors, not multi-bit errors.

Robust error recovery includes control flow transfer (typically restarting a process at a point before the error), resource release, and data restoration.

Their main recommendation for data restoration is to avoid the need for it, through having intermediate data be treated as temporary, so that restarting before the error also rolls back the data to a reliable state. This sounds similar to the concept of "transactions" in databases.

They discuss techniques particularly suitable for object-oriented languages such as C++. For example

1. Software-based ECCs for contiguous memory objects
2. Programming by Contract: verifying preconditions and postconditions, then checking the object to verify it is still in a valid state.

And, it just so happens, NASA has used C++ for major projects such as the Mars Rover.

C++ class abstraction and encapsulation enabled rapid development and testing among multiple projects and developers.

They avoided certain C++ features that could create problems:

1. Exceptions
2. Templates
3. Iostream (no console)
4. Multiple inheritance
5. Operator overloading (other than new and delete)
6. Dynamic allocation (used a dedicated memory pool and placement new to avoid the possibility of system heap corruption).

Better and clean example using JS only

Reference: TheDeveloperBlog.com

Step 1 - Create your java script and place it in your HTML page.

<script type="text/javascript">
    function ShowLoading(e) {
        var div = document.createElement('div');
        var img = document.createElement('img');
        img.src = 'loading_bar.GIF';
        div.innerHTML = "Loading...<br />";
        div.style.cssText = 'position: fixed; top: 5%; left: 40%; z-index: 5000; width: 422px; text-align: center; background: #EDDBB0; border: 1px solid #000';
        div.appendChild(img);
        document.body.appendChild(div);
        return true;
        // These 2 lines cancel form submission, so only use if needed.
        //window.event.cancelBubble = true;
        //e.stopPropagation();
    }
</script>

in your form call the java script function on submit event.

<form runat="server"  onsubmit="ShowLoading()">
</form>

Soon after you submit the form, it will show you the loading image.

You have extra brackets in Hours property;

public  object Hours { get; set; }}

You could use a recursive scalar function:-

set nocount on

create table location (
    id int,
    name varchar(50),
    parent int
)
insert into location values
    (1,'france',null),
    (2,'paris',1),
    (3,'belleville',2),
    (4,'lyon',1),
    (5,'vaise',4),
    (6,'united kingdom',null),
    (7,'england',6),
    (8,'manchester',7),
    (9,'fallowfield',8),
    (10,'withington',8)
go
create function dbo.breadcrumb(@child int)
returns varchar(1024)
as begin
    declare @returnValue varchar(1024)=''
    declare @parent int
    select @returnValue+=' > '+name,@parent=parent
    from location
    where id=@child
    if @parent is not null
        set @returnValue=dbo.breadcrumb(@parent)+@returnValue
    return @returnValue
end
go

declare @location int=1
while @location<=10 begin
    print dbo.breadcrumb(@location)+' >'
    set @location+=1
end

produces:-

 > france >
 > france > paris >
 > france > paris > belleville >
 > france > lyon >
 > france > lyon > vaise >
 > united kingdom >
 > united kingdom > england >
 > united kingdom > england > manchester >
 > united kingdom > england > manchester > fallowfield >
 > united kingdom > england > manchester > withington >

TL;DR

Transient objects are always different; a new instance is provided to every controller and every service.

Scoped objects are the same within a request, but different across different requests.

Singleton objects are the same for every object and every request.

For more clarification, this example from .NET documentation shows the difference:

To demonstrate the difference between these lifetime and registration options, consider a simple interface that represents one or more tasks as an operation with a unique identifier, OperationId. Depending on how we configure the lifetime for this service, the container will provide either the same or different instances of the service to the requesting class. To make it clear which lifetime is being requested, we will create one type per lifetime option:

using System;

namespace DependencyInjectionSample.Interfaces
{
    public interface IOperation
    {
        Guid OperationId { get; }
    }

    public interface IOperationTransient : IOperation
    {
    }

    public interface IOperationScoped : IOperation
    {
    }

    public interface IOperationSingleton : IOperation
    {
    }

    public interface IOperationSingletonInstance : IOperation
    {
    }
}

We implement these interfaces using a single class, Operation, that accepts a GUID in its constructor, or uses a new GUID if none is provided:

using System;
using DependencyInjectionSample.Interfaces;
namespace DependencyInjectionSample.Classes
{
    public class Operation : IOperationTransient, IOperationScoped, IOperationSingleton, IOperationSingletonInstance
    {
        Guid _guid;
        public Operation() : this(Guid.NewGuid())
        {

        }

        public Operation(Guid guid)
        {
            _guid = guid;
        }

        public Guid OperationId => _guid;
    }
}

Next, in ConfigureServices, each type is added to the container according to its named lifetime:

services.AddTransient<IOperationTransient, Operation>();
services.AddScoped<IOperationScoped, Operation>();
services.AddSingleton<IOperationSingleton, Operation>();
services.AddSingleton<IOperationSingletonInstance>(new Operation(Guid.Empty));
services.AddTransient<OperationService, OperationService>();

Note that the IOperationSingletonInstance service is using a specific instance with a known ID of Guid.Empty, so it will be clear when this type is in use. We have also registered an OperationService that depends on each of the other Operation types, so that it will be clear within a request whether this service is getting the same instance as the controller, or a new one, for each operation type. All this service does is expose its dependencies as properties, so they can be displayed in the view.

using DependencyInjectionSample.Interfaces;

namespace DependencyInjectionSample.Services
{
    public class OperationService
    {
        public IOperationTransient TransientOperation { get; }
        public IOperationScoped ScopedOperation { get; }
        public IOperationSingleton SingletonOperation { get; }
        public IOperationSingletonInstance SingletonInstanceOperation { get; }

        public OperationService(IOperationTransient transientOperation,
            IOperationScoped scopedOperation,
            IOperationSingleton singletonOperation,
            IOperationSingletonInstance instanceOperation)
        {
            TransientOperation = transientOperation;
            ScopedOperation = scopedOperation;
            SingletonOperation = singletonOperation;
            SingletonInstanceOperation = instanceOperation;
        }
    }
}

To demonstrate the object lifetimes within and between separate individual requests to the application, the sample includes an OperationsController that requests each kind of IOperation type as well as an OperationService. The Index action then displays all of the controller’s and service’s OperationId values.

using DependencyInjectionSample.Interfaces;
using DependencyInjectionSample.Services;
using Microsoft.AspNetCore.Mvc;

namespace DependencyInjectionSample.Controllers
{
    public class OperationsController : Controller
    {
        private readonly OperationService _operationService;
        private readonly IOperationTransient _transientOperation;
        private readonly IOperationScoped _scopedOperation;
        private readonly IOperationSingleton _singletonOperation;
        private readonly IOperationSingletonInstance _singletonInstanceOperation;

        public OperationsController(OperationService operationService,
            IOperationTransient transientOperation,
            IOperationScoped scopedOperation,
            IOperationSingleton singletonOperation,
            IOperationSingletonInstance singletonInstanceOperation)
        {
            _operationService = operationService;
            _transientOperation = transientOperation;
            _scopedOperation = scopedOperation;
            _singletonOperation = singletonOperation;
            _singletonInstanceOperation = singletonInstanceOperation;
        }

        public IActionResult Index()
        {
            // ViewBag contains controller-requested services
            ViewBag.Transient = _transientOperation;
            ViewBag.Scoped = _scopedOperation;
            ViewBag.Singleton = _singletonOperation;
            ViewBag.SingletonInstance = _singletonInstanceOperation;

            // Operation service has its own requested services
            ViewBag.Service = _operationService;
            return View();
        }
    }
}

Now two separate requests are made to this controller action:

Observe which of the OperationId values varies within a request, and between requests.

• Transient objects are always different; a new instance is provided to every controller and every service.

• Scoped objects are the same within a request, but different across different requests

• Singleton objects are the same for every object and every request (regardless of whether an instance is provided in ConfigureServices)

The openssh project lists several Java alternatives, Trilead SSH for Java seems to fit what you're asking for.

I know DOS and cmd prompt DOES NOT LIKE spaces in folder names. Your code starts with

cd c:\Program files\IIS Express

and it's trying to go to c:\Program in stead of C:\"Program Files"

Change the folder name and *.exe name. Hope this helps

It looks like details is an array of hashes. So item inside of your block will be the whole hash. Therefore, to check the :qty key, you'd do something like the following:

details.select{ |item| item[:qty] != "" }

That will give you all items where the :qty key isn't an empty string.

official select documentation

Here is a clearer solution.

def freeze(o):
  if isinstance(o,dict):
    return frozenset({ k:freeze(v) for k,v in o.items()}.items())

  if isinstance(o,list):
    return tuple([freeze(v) for v in o])

  return o


def make_hash(o):
    """
    makes a hash out of anything that contains only list,dict and hashable types including string and numeric types
    """
    return hash(freeze(o))  

For the first solution proposed by Joe Kington ( .copy_from_bbox & .draw_artist & canvas.blit), I had to capture the backgrounds after the fig.canvas.draw() line, otherwise the background had no effect and I got the same result as you mentioned. If you put it after the fig.show() it still does not work as proposed by Michael Browne.

So just put the background line after the canvas.draw():

[...]
fig.show()

# We need to draw the canvas before we start animating...
fig.canvas.draw()

# Let's capture the background of the figure
backgrounds = [fig.canvas.copy_from_bbox(ax.bbox) for ax in axes]

if you need the batch file to schedule the backup, the SQL management tools have scheduled tasks built in...

I work with gcc 7.2. I specifically needed a function to be non-inlined, because it had to be instantiated in a library. I tried the __attribute__((noinline)) answer, as well as the asm("") answer. Neither one solved the problem.

Finally, I figured that defining a static variable inside the function will force the compiler to allocate space for it in the static variable block, and to issue an initialization for it when the function is first called.

This is sort of a dirty trick, but it works.

A neato trick with groupby is to run length encoding in one line:

[(c,len(list(cgen))) for c,cgen in groupby(some_string)]

will give you a list of 2-tuples where the first element is the char and the 2nd is the number of repetitions.

Edit: Note that this is what separates itertools.groupby from the SQL GROUP BY semantics: itertools doesn't (and in general can't) sort the iterator in advance, so groups with the same "key" aren't merged.

**Replacing  href attribut value to other** 
 
 <div class="cpt">
   <a href="/ref/ref/testone.html">testoneLink</a>
 </div>

  <div class="test" >
      <a href="/ref/ref/testtwo.html">testtwoLInk</a>
  </div>

 <!--Remove first default Link from href attribut -->
<script>
     Remove first default Link from href attribut
    $(".cpt a").removeAttr("href");
    
    Add  Link to same href attribut
    var testurl= $(".test").find("a").attr("href");
    $(".test a").attr('href', testurl);
</script>

This bash script is for N parallel threads. Each argument is a command.

trap will kill all subprocesses when SIGINT is catched.
wait $PID_LIST is waiting each process to complete. When all processes have completed, the program exits.

#!/bin/bash

for cmd in "$@"; do {
  echo "Process \"$cmd\" started";
  $cmd & pid=$!
  PID_LIST+=" $pid";
} done

trap "kill $PID_LIST" SIGINT

echo "Parallel processes have started";

wait $PID_LIST

echo
echo "All processes have completed";

Save this script as parallel_commands and make it executable.
This is how to use this script:

parallel_commands "cmd arg0 arg1 arg2" "other_cmd arg0 arg2 arg3"

Example:

parallel_commands "sleep 1" "sleep 2" "sleep 3" "sleep 4"

Start 4 parallel sleep and waits until "sleep 4" finishes.

use an infinity loop like what you have originally done. Its cleanest and you can incorporate many conditions as you wish

while 1:
  if condition1 and condition2:
      break
  ...
  ...
  if condition3: break
  ...
  ...

In another scenario just I would like to add is In my scenario, the name space was different for controller as it was mistake of copying controller from another project.

Vim :help window explains the confusion "tabs vs buffers" pretty well.

A buffer is the in-memory text of a file.
A window is a viewport on a buffer.
A tab page is a collection of windows.

Opening multiple files is achieved in vim with buffers. In other editors (e.g. notepad++) this is done with tabs, so the name tab in vim maybe misleading.

Windows are for the purpose of splitting the workspace and displaying multiple files (buffers) together on one screen. In other editors this could be achieved by opening multiple GUI windows and rearranging them on the desktop.

Finally in this analogy vim's tab pages would correspond to multiple desktops, that is different rearrangements of windows.

As vim help: tab-page explains a tab page can be used, when one wants to temporarily edit a file, but does not want to change anything in the current layout of windows and buffers. In such a case another tab page can be used just for the purpose of editing that particular file.

Of course you have to remember that displaying the same file in many tab pages or windows would result in displaying the same working copy (buffer).

Use prop() instead of attr() to set the value of checked. Also use :checkbox in find method instead of input and be specific.

Live Demo

$("#news_list tr").click(function() {
    var ele = $(this).find('input');
    if(ele.is(':checked')){
        ele.prop('checked', false);
        $(this).removeClass('admin_checked');
    }else{
        ele.prop('checked', true);
        $(this).addClass('admin_checked');
    }
});

Use prop instead of attr for properties like checked

As of jQuery 1.6, the .attr() method returns undefined for attributes that have not been set. To retrieve and change DOM properties such as the checked, selected, or disabled state of form elements, use the .prop() method

Hope this helps somebody!

<style> html { scroll-behavior: smooth;} </style>
<a id="top"></>
<!--content here-->
<a href="#top">Back to top..</a>

ng-click "$watch(edit($index), open())"

Another way would be:

string="Paris, France, Europe"
IFS=', ' arr=(${string})

Now your elements are stored in "arr" array. To iterate through the elements:

for i in ${arr[@]}; do echo $i; done

In plain-old JavaScript you can do this:

var inputs = document.getElementsByTagName('input');

for(var i = 0; i < inputs.length; i++) {
    if(inputs[i].type.toLowerCase() == 'text') {
        alert(inputs[i].value);
    }
}

In jQuery, you would just do:

// select all inputs of type 'text' on the page
$("input:text")

// hide all text inputs which are descendants of div class="foo"
$("div.foo input:text").hide();

Basically, this will not work out

Format("20130423014854","yyyy-MM-dd hh:mm:ss")

the format function will only work if your string has correct format

Format (#17/04/2004#, "yyyy/mm/dd")

And you need to specify, what datatype of field [Date] is, because I can't put this value 2013-04-23 13:48:54.0 under a General Date field (I use MS access2007). You might want to view this topic: select date in between

selection opertion is used to select a subset of tuple from the relation that satisfied selection condition It filter out those tuple that satisfied the condition .Selection opertion can be visualized as horizontal partition into two set of tuple - those tuple satisfied the condition are selected and those tuple do not select the condition are discarded sigma (R) projection opertion is used to select a attribute from the relation that satisfied selection condition . It filter out only those tuple that satisfied the condition . The projection opertion can be visualized as a vertically partition into two part -are those satisfied the condition are selected other discarded ?(R) attribute list is a num of attribute

To answer the second part of your question - there are no pointers in PHP.

When working with objects, you generally pass by reference rather than by value - so in some ways this operates like a pointer, but is generally completely transparent.

This does depend on the version of PHP you are using.

You can completely avoid manually doing the transforms and scaling yourself, as suggested by an0 in this answer here:

- (UIImage *)normalizedImage {
    if (self.imageOrientation == UIImageOrientationUp) return self; 

    UIGraphicsBeginImageContextWithOptions(self.size, NO, self.scale);
    [self drawInRect:(CGRect){0, 0, self.size}];
    UIImage *normalizedImage = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();
    return normalizedImage;
}

The documentation for the UIImage methods size and drawInRect explicitly states that they take into account orientation.

According to https://groups.google.com/forum/?fromgroups#!topic/mockito/9WUvkhZUy90, you should rephrase your

when(bar.getFoo()).thenReturn(fooBar)

to

doReturn(fooBar).when(bar).getFoo()

I just had this same problem:

1. rails d migration fuu -this deleted the migration with the last timestamp
2. rails d migration fuu -this deleted the other migration
3. use git status to check that is not on the untracked files anymore
4. rails g migration fuu

That fixed it for me

you can try to export as "Runnable jar" in eclipse. I have also problems, when i export as "jar", but i have never problems when i export as "Runnable jar".

tl;dr

LocalDate.parse( "2011-01-01" )
         .format( DateTimeFormatter.ofPattern( "MM-dd-uuuu" ) ) 

java.time

The other Answers are now outdated. The troublesome old date-time classes such as java.util.Date, java.util.Calendar, and java.text.SimpleDateFormat are now legacy, supplanted by the java.time classes.

ISO 8601

The input string 2011-01-01 happens to comply with the ISO 8601 standard formats for date-time text. The java.time classes use these standard formats by default when parsing/generating strings. So no need to specify a formatting pattern.

LocalDate

The LocalDate class represents a date-only value without time-of-day and without time zone.

LocalDate ld = LocalDate.parse( "2011-01-01" ) ;

Generate a String in the same format by calling toString.

String output = ld.toString() ;

2011-01-01

DateTimeFormatter

To parse/generate other formats, use a DateTimeFormatter.

DateTimeFormatter f = DateTimeFormatter.ofPattern( "MM-dd-uuuu" ) ;
String output = ld.format( f ) ;

01-01-2011

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

Where to obtain the java.time classes?

• Java SE 8, Java SE 9, and later
  • Built-in.
  • Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and Java SE 7
  • Much of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • The ThreeTenABP project adapts ThreeTen-Backport (mentioned above) for Android specifically.
  • See How to use ThreeTenABP….

The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval, YearWeek, YearQuarter, and more.

As others have said, this is bad practice, but if you don't have a choice because you need to integrate with a third-party library that uses the default package, then you could create your own class in the default package and access the other class that way. Classes in the default package basically share a single namespace, so you can access the other class even if it resides in a separate JAR file. Just make sure the JAR file is in the classpath.

This trick doesn't work if your class is not in the default package.

Try this instead:

print_r($sth->errorInfo());

Add this before your prepare:

$this->pdo->setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_WARNING );

This will change the PDO error reporting type and cause it to emit a warning whenever there is a PDO error. It should help you track it down, although your errorInfo should have bet set.

Sure:

try {
   throw new Exception('Something bad');
} catch (Exception $e) {
    // Do nothing
}

You might want to go have a read of the PHP documentation on Exceptions.

I am also facing this problem.

Problem in IE is newWin.document.write(divToPrint.innerHTML);

when we remove this line print function in IE is working. but again problem still exist about the content of page.

You can open the page using window.open, and write the content in that page. then print function will work in IE.This is alternate solution.

Best luck.

@Pratik

As simple as this !

var json_data = {"2013-01-21":1,"2013-01-22":7};
var result = [json_data];
console.log(result);

You can also try this, after injecting $window service.

$window.location.reload();

I've taken Irritate's answer and refactored it so as to minimize the computational steps for subsequent computations by factoring it into the fewest constants. The motivation is to allow a scaler to be trained on one set of data, and then be run on new data (for an ML algo). In effect, it's much like SciKit's preprocessing MinMaxScaler for Python in usage.

Thus, x' = (b-a)(x-min)/(max-min) + a (where b!=a) becomes x' = x(b-a)/(max-min) + min(-b+a)/(max-min) + a which can be reduced to two constants in the form x' = x*Part1 + Part2.

Here's a C# implementation with two constructors: one to train, and one to reload a trained instance (e.g., to support persistence).

public class MinMaxColumnSpec
{
    /// <summary>
    /// To reduce repetitive computations, the min-max formula has been refactored so that the portions that remain constant are just computed once.
    /// This transforms the forumula from
    /// x' = (b-a)(x-min)/(max-min) + a
    /// into x' = x(b-a)/(max-min) + min(-b+a)/(max-min) + a
    /// which can be further factored into
    /// x' = x*Part1 + Part2
    /// </summary>
    public readonly double Part1, Part2;

    /// <summary>
    /// Use this ctor to train a new scaler.
    /// </summary>
    public MinMaxColumnSpec(double[] columnValues, int newMin = 0, int newMax = 1)
    {
        if (newMax <= newMin)
            throw new ArgumentOutOfRangeException("newMax", "newMax must be greater than newMin");

        var oldMax = columnValues.Max();
        var oldMin = columnValues.Min();

        Part1 = (newMax - newMin) / (oldMax - oldMin);
        Part2 = newMin + (oldMin * (newMin - newMax) / (oldMax - oldMin));
    }

    /// <summary>
    /// Use this ctor for previously-trained scalers with known constants.
    /// </summary>
    public MinMaxColumnSpec(double part1, double part2)
    {
        Part1 = part1;
        Part2 = part2;
    }

    public double Scale(double x) => (x * Part1) + Part2;
}

Adding a space before the EOF delimiter allows to avoid cmd:

- shell: |
    cat <<' EOF'
    This is a test.
    EOF

You could also just do this:

mysql_query("
    UPDATE member_profile 
    SET points = points + 1
    WHERE user_id = '".$userid."'
");

I don't think you can set that option there. You will have to use jQuery.ajax() with the appropriate parameters (basically getJSON just wraps that call into an easier API, as well).

EncodeAndSend is not a static function, which means it can be called on an instance of the class CPMSifDlg. You cannot write this:

 CPMSifDlg::EncodeAndSend(/*...*/);  //wrong - EncodeAndSend is not static

It should rather be called as:

 CPMSifDlg dlg; //create instance, assuming it has default constructor!
 dlg.EncodeAndSend(/*...*/);   //correct

You have to wrap \n or \r in "", not ''. When using single quotes escape sequences will not be interpreted (except \' and \\).

The manual states:

If the string is enclosed in double-quotes ("), PHP will interpret more escape sequences for special characters:

• \n linefeed (LF or 0x0A (10) in ASCII)

• \r carriage return (CR or 0x0D (13) in ASCII)\

• (...)

Because you're trying to add a click event to a submit input you will need to prevent the normal flow that this will do that is submit the form.

You can also use $(document).ready()

But since you have your script tag at the end of the page the DOM is already loaded.

To prevent the default you will need something like this:

$("form").on('submit',function(e){
    e.preventDefault();
    $("#dsf").val("changed value")

})

If the element wasn't a submit input it will be as simple as

$("#cd").click(function(){
    $("#dsf").val("changed value")

})

See this Fiddle

Opposite up is children(), but opposite in position is prepend(). Here a very good tutorial.

change image captcha refresh

html:

 <img id="captcha_img" src="http://localhost/captcha.php" /> 

jquery:

$("#captcha_img").click(function()
    {
        var capt_rand=Math.floor((Math.random() * 9999) + 1);
        $("#captcha_img").attr("src","http://localhost/captcha.php?" + capt_rand);
    });

x = y = 5 is equivalent to x = (y = 5), because the assignment operators "group" right to left, which works. Meaning: assign 5 to y, leaving the number 5; and then assign that 5 to x.

This is not the same as (x = y) = 5, which doesn't work! Meaning: assign the value of y to x, leaving the value of y; and then assign 5 to, umm..., what exactly?

When you mix the different kinds of assignment operators, <- binds tighter than =. So x = y <- 5 is interpreted as x = (y <- 5), which is the case that makes sense.

Unfortunately, x <- y = 5 is interpreted as (x <- y) = 5, which is the case that doesn't work!

See ?Syntax and ?assignOps for the precedence (binding) and grouping rules.

HTML

<mat-form-field>
<mat-select [(ngModel)]="modeSelect" placeholder="Mode">
  <mat-option *ngFor="let obj of Array"  [value]="obj.value">{{obj.value}}</mat-option>

Now set your default value to

modeSelect

, where you are getting the values in Array variable.

In my case, there is a redundant \ in the like following:

Return converted image without saving:

# Take in base64 string and return cv image
def stringToRGB(base64_string):
    imgdata = base64.b64decode(str(base64_string))
    image = Image.open(io.BytesIO(imgdata))
    return cv2.cvtColor(np.array(image), cv2.COLOR_BGR2RGB)

here is a simple javascript for that

call this when you need to scroll the screen to an element which has id="yourSpecificElementId"

window.scroll(0,findPos(document.getElementById("yourSpecificElementId")));

and you need this function for the working:

//Finds y value of given object
function findPos(obj) {
    var curtop = 0;
    if (obj.offsetParent) {
        do {
            curtop += obj.offsetTop;
        } while (obj = obj.offsetParent);
    return [curtop];
    }
}

the screen will be scrolled to your specific element.

// These are three very simple and concise answers:

function fun() {
    console.log(this.prop1, this.prop2, this.prop3);
}

let obj = { prop1: 'one', prop2: 'two', prop3: 'three' };

let bound = fun.bind(obj);

setTimeout(bound, 3000);

 // or

function funOut(par1, par2, par3) {

  return function() { 

    console.log(par1, par2, par3);

  }
};

setTimeout(funOut('one', 'two', 'three'), 5000);

 // or

let funny = function(a, b, c) { console.log(a, b, c); };

setTimeout(funny, 2000, 'hello', 'worldly', 'people');

If you're checking from the outside, not from the server itself, and you don't want to bother installing telnet (as it doesn't come with the last versions of Windows) or any other software, then you have native PowerShell:

Test-NetConnection -Port 800 -ComputerName 192.168.0.1 -InformationLevel Detailed

(Unfortunately this only works with PowerShell 4.0 or newer. To check your PowerShell version, type $PSVersionTable.)

PS: Note, these days there are some claims on the twittersphere that hint that this answer could be improved by mentioning "Test-Connection" from PowerShell Core, or the shortcut "tnc". See https://twitter.com/david_obrien/status/1214082339203993600 and help me edit this answer to improve it please!

(If you have a PSVersion < 4.0, you're out of luck. Check this table:

Even though you can upgrade your version of PowerShell by installing the Windows Management Framework 4.0, it didn't do the trick for me, Test-NetConnection cmdlet is still not available).

This post is old, but I change your code to:

scope.$watch("assignments", function (value) {//I change here
  var val = value || null;            
  if (val)
    element.dataTable({"bDestroy": true});
  });
}

see jsfiddle.

I hope it helps you

Just Set it up like this

{% set active_link = recordtype -%}

#!/bin/bash
#file getActivity.sh
package_name=$1
#launch app by package name
adb shell monkey -p ${package_name} -c android.intent.category.LAUNCHER 1;
sleep 1;
#get Activity name
adb shell logcat -d | grep 'START u0' | tail -n 1 | sed 's/.*cmp=\(.*\)} .*/\1/g'

sample:

getActivity.sh com.tencent.mm
com.tencent.mm/.ui.LauncherUI

If you want convert Keys:

List<string> listNumber = dicNumber.Keys.ToList();

else if you want convert Values:

List<string> listNumber = dicNumber.Values.ToList();

As of April 2018, Chrome's autoplay policies changed:

"Chrome's autoplay policies are simple:

• Muted autoplay is always allowed.

Autoplay with sound is allowed if:

• User has interacted with the domain (click, tap, etc.).
• On desktop, the user's Media Engagement Index threshold has been crossed, meaning the user has previously play video with sound.
• On mobile, the user has added the site to his or her home screen.

Also

• Top frames can delegate autoplay permission to their iframes to allow autoplay with sound. "

Chrome's developer site has more information, including some programming examples, which can be found here: https://developers.google.com/web/updates/2017/09/autoplay-policy-changes

You can also take a look at the built-in .NET tracing facilities too. There's a set of trace listeners that allow you to output to a log file, but you can configure it to log into the Event viewer, or to a database (or all of them simultaneously).

http://www.codeguru.com/csharp/.net/net_debugging/tracing/article.php/c5919/NET-Tracing-Tutorial.htm

The lmplot function returns a FacetGrid instance. This object has a method called set, to which you can pass key=value pairs and they will be set on each Axes object in the grid.

Secondly, you can set only one side of an Axes limit in matplotlib by passing None for the value you want to remain as the default.

Putting these together, we have:

g = sns.lmplot('X', 'Y', df, col='Z', sharex=False, sharey=False)
g.set(ylim=(0, None))

You got a ninja ')'.

Try :

<div *ngIf="currentStatus !== 'open' || currentStatus !== 'reopen'">

I got this error in a JobService from the following code:

    } else {
        Logger.debug(TAG, "BluetoothAdapter isn't on so will attempting to turn on and will retry starting scanning in a few seconds");
        getBluetoothAdapter().enable();
        (new Handler()).postDelayed(new Runnable() {
            @Override
            public void run() {
                startScanningBluetooth();
            }
        }, 5000);
    }

Now the code doesn't throw the RuntimeException anymore.

All the methods collected with examples

Intro

Actually, there are many ways to do it. Some are harder from others, but it is up to you which one suits you best. I will try to showcase them all.

#1 Programatically in your app

Seems to be the easiest, but you will need to recompile your app to change those settings. Personally, I don't like it but it works fine.

Example:

import org.apache.log4j.{Level, Logger}

val rootLogger = Logger.getRootLogger()
rootLogger.setLevel(Level.ERROR)

Logger.getLogger("org.apache.spark").setLevel(Level.WARN)
Logger.getLogger("org.spark-project").setLevel(Level.WARN)

You can achieve much more just using log4j API.
Source: [Log4J Configuration Docs, Configuration section]

#2 Pass log4j.properties during spark-submit

This one is very tricky, but not impossible. And my favorite.

Log4J during app startup is always looking for and loading log4j.properties file from classpath.

However, when using spark-submit Spark Cluster's classpath has precedence over app's classpath! This is why putting this file in your fat-jar will not override the cluster's settings!

Add -Dlog4j.configuration=<location of configuration file> to spark.driver.extraJavaOptions (for the driver) or
spark.executor.extraJavaOptions (for executors).

Note that if using a file, the file: protocol should be explicitly provided, and the file needs to exist locally on all the nodes.

To satisfy the last condition, you can either upload the file to the location available for the nodes (like hdfs) or access it locally with driver if using deploy-mode client. Otherwise:

upload a custom log4j.properties using spark-submit, by adding it to the --files list of files to be uploaded with the application.

Source: Spark docs, Debugging

Steps:

Example log4j.properties:

# Blacklist all to warn level
log4j.rootCategory=WARN, console

log4j.appender.console=org.apache.log4j.ConsoleAppender
log4j.appender.console.target=System.err
log4j.appender.console.layout=org.apache.log4j.PatternLayout
log4j.appender.console.layout.ConversionPattern=%d{yy/MM/dd HH:mm:ss} %p %c{1}: %m%n

# Whitelist our app to info :)
log4j.logger.com.github.atais=INFO

Executing spark-submit, for cluster mode:

spark-submit \
    --master yarn \
    --deploy-mode cluster \
    --conf "spark.driver.extraJavaOptions=-Dlog4j.configuration=file:log4j.properties" \
    --conf "spark.executor.extraJavaOptions=-Dlog4j.configuration=file:log4j.properties" \
    --files "/absolute/path/to/your/log4j.properties" \
    --class com.github.atais.Main \
    "SparkApp.jar"

Note that you must use --driver-java-options if using client mode. Spark docs, Runtime env

Executing spark-submit, for client mode:

spark-submit \
    --master yarn \
    --deploy-mode client \
    --driver-java-options "-Dlog4j.configuration=file:/absolute/path/to/your/log4j.properties \
    --conf "spark.executor.extraJavaOptions=-Dlog4j.configuration=file:log4j.properties" \
    --files "/absolute/path/to/your/log4j.properties" \
    --class com.github.atais.Main \
    "SparkApp.jar"

Notes:

1. Files uploaded to spark-cluster with --files will be available at root dir, so there is no need to add any path in file:log4j.properties.
2. Files listed in --files must be provided with absolute path!
3. file: prefix in configuration URI is mandatory.

#3 Edit cluster's conf/log4j.properties

This changes global logging configuration file.

update the $SPARK_CONF_DIR/log4j.properties file and it will be automatically uploaded along with the other configurations.

Source: Spark docs, Debugging

To find your SPARK_CONF_DIR you can use spark-shell:

atais@cluster:~$ spark-shell 
Welcome to
      ____              __
     / __/__  ___ _____/ /__
    _\ \/ _ \/ _ `/ __/  '_/
   /___/ .__/\_,_/_/ /_/\_\   version 2.1.1
      /_/   

scala> System.getenv("SPARK_CONF_DIR")
res0: String = /var/lib/spark/latest/conf

Now just edit /var/lib/spark/latest/conf/log4j.properties (with example from method #2) and all your apps will share this configuration.

#4 Override configuration directory

If you like the solution #3, but want to customize it per application, you can actually copy conf folder, edit it contents and specify as the root configuration during spark-submit.

To specify a different configuration directory other than the default “SPARK_HOME/conf”, you can set SPARK_CONF_DIR. Spark will use the configuration files (spark-defaults.conf, spark-env.sh, log4j.properties, etc) from this directory.

Source: Spark docs, Configuration

Steps:

1. Copy cluster's conf folder (more info, method #3)
2. Edit log4j.properties in that folder (example in method #2)

3. Set SPARK_CONF_DIR to this folder, before executing spark-submit,
   example:

   export SPARK_CONF_DIR=/absolute/path/to/custom/conf
   
   spark-submit \
       --master yarn \
       --deploy-mode cluster \
       --class com.github.atais.Main \
       "SparkApp.jar"
   

Conclusion

I am not sure if there is any other method, but I hope this covers the topic from A to Z. If not, feel free to ping me in the comments!

Enjoy your way!

please import requestoptions from angular cors

    import {RequestOptions, Request, Headers } from '@angular/http';

and add request options in your code like given below

    let requestOptions = new RequestOptions({ headers:null, withCredentials: 
    true });

send request option in your api request

code snippet below-

     let requestOptions = new RequestOptions({ headers:null, 
     withCredentials: true });
     return this.http.get(this.config.baseUrl + 
     this.config.getDropDownListForProject, requestOptions)
     .map(res => 
     {
      if(res != null)
      { 
        return res.json();
        //return true;
      }
    })
  .catch(this.handleError);
   }  

and add CORS in your backend PHP code where all api request will land first.

try this and let me know if it is working or not i had a same issue i was adding CORS from angular5 that was not working then i added CORS to backend and it worked for me

It seems all the answers assume high level languages and mainly C/C++.

But the question is tagged "assembly" and in all assemblers I know (for 8bit, 16bit, 32bit and 64bit CPUs), the definitions are much more clear:

byte  = 8 bits 
word  = 2 bytes
dword = 4 bytes = 2Words (dword means "double word")
qword = 8 bytes = 2Dwords = 4Words ("quadruple word")

The best way to solve this problem would be by starting with customizing Bootstrap using their customization tools.

http://getbootstrap.com/customize/

Go down to @headings-color and change it from "inherit" to something that you would like your headers to be across the site (if you like the default just change it to #333).

Note that this will keep all your headings the same color, as you requested.

Now in order to accomplish what you want that after you make this change you can now overwrite them specifically in your own CSS to apply your own color to them. The "inherit" keyword I always have found to be a pain in frameworks.

You can use:

for await (let resolvedPromise of arrayOfPromises) {
  console.log(resolvedPromise)
}

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/for-await...of

If you wish to use Promise.all() instead you can go for Promise.allSettled() So you can have better control over rejected promises.

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise/allSettled

By lines I assume you mean rows in the table person. What you're looking for is:

select p.name
from   person p
where  p.name LIKE '%A%'; --contains the character 'A'

The above is case sensitive. For a case insensitive search, you can do:

select p.name
from   person p
where  UPPER(p.name) LIKE '%A%'; --contains the character 'A' or 'a'

For the special character, you can do:

select p.name
from   person p
where  p.name LIKE '%'||chr(8211)||'%'; --contains the character chr(8211)

The LIKE operator matches a pattern. The syntax of this command is described in detail in the Oracle documentation. You will mostly use the % sign as it means match zero or more characters.

This is the simple solution for saving some typing you can use the following steps in git bash easily..

(1) create the remote repository

git remote add origin https://{your_username}:{your_password}@github.com/{your_username}/repo.git

Note: If your password contains '@' sign use '%40' instead of that

(2) Then do anything you want with the remote repository

ex:- git push origin master

Simple way

@{
   Model.CRN = ViewBag.CRN;
}

@Html.HiddenFor(x => x.CRN)

Depending on the nature of the duplicate rows, it looks like all you want is to have case-sensitivity on those columns. Setting the collation on these columns should be what you're after:

SELECT DISTINCT p.IDNO COLLATE SQL_Latin1_General_CP1_CI_AS, p.FirstName COLLATE SQL_Latin1_General_CP1_CI_AS, p.LastName COLLATE SQL_Latin1_General_CP1_CI_AS
FROM people P

I wrote this quick example. It works for me. I only tested it with one dataset with one table inside, but I guess that may be enough for you.

Take into consideration that I treated all cells as String (not even SharedStrings). If you want to use SharedStrings you might need to tweak my sample a bit.

Edit: To make this work it is necessary to add WindowsBase and DocumentFormat.OpenXml references to project.

mainJSON.getJSONArray("source") returns a JSONArray, hence you can remove the new JSONArray.

The JSONArray contructor with an object parameter expects it to be a Collection or Array (not JSONArray)

Try this:

JSONArray jsonMainArr = mainJSON.getJSONArray("source"); 

So, say you have your View with PartialView, which have to be updated by button click:

<div class="target">
    @{ Html.RenderAction("UpdatePoints");}
</div>

<input class="button" value="update" />

There are some ways to do it. For example you may use jQuery:

<script type="text/javascript">
    $(function(){    
        $('.button').on("click", function(){        
            $.post('@Url.Action("PostActionToUpdatePoints", "Home")').always(function(){
                $('.target').load('/Home/UpdatePoints');        
            })        
        });
    });        
</script>

PostActionToUpdatePoints is your Action with [HttpPost] attribute, which you use to update points

If you use logic in your action UpdatePoints() to update points, maybe you forgot to add [HttpPost] attribute to it:

[HttpPost]
public ActionResult UpdatePoints()
{    
    ViewBag.points =  _Repository.Points;
    return PartialView("UpdatePoints");
}

• using: You are going to use it.
• namespace: To use what? A namespace.
• std: The std namespace (where features of the C++ Standard Library, such as string or vector, are declared).

After you write this instruction, if the compiler sees string it will know that you may be referring to std::string, and if it sees vector, it will know that you may be referring to std::vector. (Provided that you have included in your compilation unit the header files where they are defined, of course.)

If you don't write it, when the compiler sees string or vector it will not know what you are refering to. You will need to explicitly tell it std::string or std::vector, and if you don't, you will get a compile error.

The issue I had is that sometimes I will need to get at a value that is deeply nested. Normally you would need to do a type assertion at each level, so I went ahead and just made a method that takes a map[string]interface{} and a string key, and returns the resulting map[string]interface{}.

The issue that cropped up for me was that at some depths you will encounter a Slice instead of Map. So I also added methods to return a Slice from Map, and Map from Slice. I didnt do one for Slice to Slice, but you could easily add that if needed. Here are the methods:

package main
type Slice []interface{}
type Map map[string]interface{}

func (m Map) M(s string) Map {
   return m[s].(map[string]interface{})
}

func (m Map) A(s string) Slice {
   return m[s].([]interface{})
}

func (a Slice) M(n int) Map {
   return a[n].(map[string]interface{})
}

and example code:

package main

import (
   "encoding/json"
   "fmt"
   "log"
   "os"
)

func main() {
   o, e := os.Open("a.json")
   if e != nil {
      log.Fatal(e)
   }
   in_m := Map{}
   json.NewDecoder(o).Decode(&in_m)
   out_m := in_m.
      M("contents").
      M("sectionListRenderer").
      A("contents").
      M(0).
      M("musicShelfRenderer").
      A("contents").
      M(0).
      M("musicResponsiveListItemRenderer").
      M("navigationEndpoint").
      M("browseEndpoint")
   fmt.Println(out_m)
}

to make it as globally reuse function using jquery

HTML

<select class="select_location">
   <option value="http://localhost.com/app/page1.html">Page 1</option>
   <option value="http://localhost.com/app/page2.html">Page 2</option>
   <option value="http://localhost.com/app/page3.html">Page 3</option>
</select>

Javascript using jquery

$('.select_location').on('change', function(){
   window.location = $(this).val();
});

now you will able to reuse this function by adding .select_location class to any Select element class

EDIT: If you are using a Dockerfile for deployments these are the steps you need to take to resolve this issue.

Change your Dockerfile to include the following:

FROM mcr.microsoft.com/dotnet/core/sdk:3.1 AS build-env
ENV PATH $PATH:/root/.dotnet/tools
RUN dotnet tool install -g dotnet-ef --version 3.1.1

Also change your dotnet ef commands to be dotnet-ef

For me Arrays.asList() is the best and convenient one. I always like to initialize that way. If you are a beginner into Java Collections then I would like you to refer ArrayList initialization

The XPath spec. defines the string value of an element as the concatenation (in document order) of all of its text-node descendents.

This explains the "strange results".

"Better" results can be obtained using the expressions below:

//*[text() = 'qwerty']

The above selects every element in the document that has at least one text-node child with value 'qwerty'.

//*[text() = 'qwerty' and not(text()[2])]

The above selects every element in the document that has only one text-node child and its value is: 'qwerty'.

Supposedly you can do this on windows with the growl for windows javascript API:

http://ajaxian.com/archives/growls-for-windows-and-a-web-notification-api

Your users will have to install growl though.

Eventually this is going to be part of google gears, in the form of the NotificationAPI:

http://code.google.com/p/gears/wiki/NotificationAPI

So I would recommend using the growl approach for now, falling back to window title updates if possible, and already engineering in attempts to use the Gears Notification API, for when it eventually becomes available.

mylist[c(5,7,9)] should do it.

You want the sublists returned as sublists of the result list; you don't use [[]] (or rather, the function is [[) for that -- as Dason mentions in comments, [[ grabs the element.

REPAIR TABLE tbl_name USE_FRM;

Command only run when MySQL 'Storage Engine' type should be 'MyISAM'

Hope this helps

I've also had problem with data being lost after application is restarted. Adding this helped:

webView.getSettings().setDatabasePath("/data/data/" + webView.getContext().getPackageName() + "/databases/");

$mail = new PHPMailer();

$mail->AddAddress($email); 
$mail->From     = $from;
$mail->Subject  = $subject; 
$mail->Body     = $body;

if($mail->Send()){
    echo 'Email Successfully Sent!';
}else{
    echo 'Email Sending Failed!';
}

the simplest way to handle email sending successful or failed...

They are extension methods. Welcome to a whole new fluent world. :)

You should use some form of the String#equals(Object) method. However, there is some subtlety in how you should do it:

If you have a string literal then you should use it like this:

"Hello".equals(someString);

This is because the string literal "Hello" can never be null, so you will never run into a NullPointerException.

If you have a string and another object then you should use:

myString.equals(myObject);

You can make sure you are actually getting string equality by doing this. For all you know, myObject could be of a class that always returns true in its equals method!

Start with the object less likely to be null because this:

String foo = null;
String bar = "hello";
foo.equals(bar);

will throw a NullPointerException, but this:

String foo = null;
String bar = "hello";
bar.equals(foo);

will not. String#equals(Object) will correctly handle the case when its parameter is null, so you only need to worry about the object you are dereferencing--the first object.

echo '<pre>';
var_dump($_SESSION);
echo '</pre>';

Or you can use print_r if you don't care about types. If you use print_r, you can make the second argument TRUE so it will return instead of echo, useful for...

echo '<pre>' . print_r($_SESSION, TRUE) . '</pre>';

If your looking for a (US) phone number to be converted in real time. I suggest using this extension. This method works perfectly without filling in the numbers backwards. The String.Format solution appears to work backwards. Just apply this extension to your string.

public static string PhoneNumberFormatter(this string value)
{
    value = new Regex(@"\D").Replace(value, string.Empty);
    value = value.TrimStart('1');

    if (value.Length == 0)
        value = string.Empty;
    else if (value.Length < 3)
        value = string.Format("({0})", value.Substring(0, value.Length));
    else if (value.Length < 7)
        value = string.Format("({0}) {1}", value.Substring(0, 3), value.Substring(3, value.Length - 3));
    else if (value.Length < 11)
        value = string.Format("({0}) {1}-{2}", value.Substring(0, 3), value.Substring(3, 3), value.Substring(6));
    else if (value.Length > 10)
    {
        value = value.Remove(value.Length - 1, 1);
        value = string.Format("({0}) {1}-{2}", value.Substring(0, 3), value.Substring(3, 3), value.Substring(6));
    }
    return value;
}

The accepted answer does not show 0 in integer place on giving input like 0.299. It shows .3 in WPF UI. So my suggestion to use following string format

<TextBox Text="{Binding Value,  StringFormat={}{0:#,0.0}}" 

Adding this to your code android:focusableInTouchMode="true" will make sure that your keypad doesn't appear on startup for your edittext box. You want to add this line to your linear layout that contains the EditTextBox. You should be able to play with this to solve both your problems. I have tested this. Simple solution.

ie: In your app_list_view.xml file

<LinearLayout 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" 
    android:orientation="vertical" 
    android:focusableInTouchMode="true">
    <EditText 
        android:id="@+id/filter_edittext"       
        android:layout_width="fill_parent" 
        android:layout_height="wrap_content" 
        android:hint="Search" 
        android:inputType="text" 
        android:maxLines="1"/>
    <ListView 
        android:id="@id/android:list" 
        android:layout_height="fill_parent"
        android:layout_weight="1.0" 
        android:layout_width="fill_parent" 
        android:focusable="true" 
        android:descendantFocusability="beforeDescendants"/>
</LinearLayout> 

------------------ EDIT: To Make keyboard appear on startup -----------------------

This is to make they Keyboard appear on the username edittextbox on startup. All I've done is added an empty Scrollview to the bottom of the .xml file, this puts the first edittext into focus and pops up the keyboard. I admit this is a hack, but I am assuming you just want this to work. I've tested it, and it works fine.

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:orientation="vertical" 
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:paddingLeft="20dip"  
    android:paddingRight="20dip">
    <EditText 
        android:id="@+id/userName" 
        android:singleLine="true" 
        android:layout_width="fill_parent"  
        android:layout_height="wrap_content" 
        android:hint="Username"  
        android:imeOptions="actionDone" 
        android:inputType="text"
        android:maxLines="1"
       />
    <EditText 
        android:id="@+id/password" 
        android:password="true" 
        android:singleLine="true"  
        android:layout_width="fill_parent" 
        android:layout_height="wrap_content" 
        android:hint="Password" />
    <ScrollView
        android:id="@+id/ScrollView01"  
        android:layout_height="fill_parent"   
        android:layout_width="fill_parent"> 
    </ScrollView>
</LinearLayout>

If you are looking for a more eloquent solution, I've found this question which might help you out, it is not as simple as the solution above but probably a better solution. I haven't tested it but it apparently works. I think it is similar to the solution you've tried which didn't work for you though.

Hope this is what you are looking for.

Cheers!

The easiest way for me is just like:

            try {
                FileWriter writer = new FileWriter("C:/Your/Absolute/Path/YourFile.txt");
                writer.write("Wow, this is so easy!");
                writer.close();
            } catch (IOException e) {
                e.printStackTrace();
            }

Useful tips & tricks:

• Give it a certain path:

  new FileWriter("C:/Your/Absolute/Path/YourFile.txt");

• New line

  writer.write("\r\n");

• Append lines into existing txt

  new FileWriter("log.txt");

Hope it works!

The <button> element, when placed in a form, will submit the form automatically unless otherwise specified. You can use the following 2 strategies:

1. Use <button type="button"> to override default submission behavior
2. Use event.preventDefault() in the onSubmit event to prevent form submission

Solution 1:

• Advantage: simple change to markup
• Disadvantage: subverts default form behavior, especially when JS is disabled. What if the user wants to hit "enter" to submit?

Insert extra type attribute to your button markup:

<button id="button" type="button" value="send" class="btn btn-primary">Submit</button>

Solution 2:

• Advantage: form will work even when JS is disabled, and respects standard form UI/UX such that at least one button is used for submission

Prevent default form submission when button is clicked. Note that this is not the ideal solution because you should be in fact listening to the submit event, not the button click event:

$(document).ready(function () {
  // Listen to click event on the submit button
  $('#button').click(function (e) {

    e.preventDefault();

    var name = $("#name").val();
    var email = $("#email").val();

    $.post("process.php", {
      name: name,
      email: email
    }).complete(function() {
        console.log("Success");
      });
  });
});

Better variant:

In this improvement, we listen to the submit event emitted from the <form> element:

$(document).ready(function () {
  // Listen to submit event on the <form> itself!
  $('#main').submit(function (e) {

    e.preventDefault();

    var name = $("#name").val();
    var email = $("#email").val();

    $.post("process.php", {
      name: name,
      email: email
    }).complete(function() {
        console.log("Success");
      });
  });
});

Even better variant: use .serialize() to serialize your form, but remember to add name attributes to your input:

The name attribute is required for .serialize() to work, as per jQuery's documentation:

For a form element's value to be included in the serialized string, the element must have a name attribute.

<input type="text" id="name" name="name" class="form-control mb-2 mr-sm-2 mb-sm-0" id="inlineFormInput" placeholder="Jane Doe">
<input type="text" id="email" name="email" class="form-control" id="inlineFormInputGroup" placeholder="[email protected]">

And then in your JS:

$(document).ready(function () {
  // Listen to submit event on the <form> itself!
  $('#main').submit(function (e) {

    // Prevent form submission which refreshes page
    e.preventDefault();

    // Serialize data
    var formData = $(this).serialize();

    // Make AJAX request
    $.post("process.php", formData).complete(function() {
      console.log("Success");
    });
  });
});

If you are using CentOS or another Linux flavour then just do Ctrl+R at the prompt and type git.

If you keep hitting Ctrl+R this will do a reverse search through your history for commands that start with git

how will I know that some tables are locked?

You can use SHOW OPEN TABLES command to view locked tables.

how do I unlock tables manually?

If you know the session ID that locked tables - 'SELECT CONNECTION_ID()', then you can run KILL command to terminate session and unlock tables.

In Xcode 6, you can do this mostly right in Xcode:

1. Go to Xcode -> Preferences -> Accounts.
2. Choose your Apple ID in the left column.
3. In the right pane, click the "View Details..." button.
4. Right-click on the provisioning profile you want to delete, then click "Show Details".
5. A Finder window will open up with the provisioning profile highlighted.
6. Delete the selected provisioning profile.

This only applies to question 1.

I have an app that runs on Windows and uses a multi-line MFC editor box.
The editor box expects CRLF linebreaks, but I need to parse the text enterred
with some really big/nasty regexs'.

I didn't want to be stressing about this while writing the regex, so
I ended up normalizing back and forth between the parser and editor so that
the regexs' just use \n. I also trap paste operations and convert them for the boxes.

This does not take much time.
This is what I use.

 boost::regex  CRLFCRtoLF (
     " \\r\\n | \\r(?!\\n) "
     , MODx);

 boost::regex  CRLFCRtoCRLF (
     " \\r\\n?+ | \\n "
     , MODx);


 // Convert (All style) linebreaks to linefeeds 
 // ---------------------------------------
 void ReplaceCRLFCRtoLF( string& strSrc, string& strDest )
 {
    strDest  = boost::regex_replace ( strSrc, CRLFCRtoLF, "\\n" );
 }

 // Convert linefeeds to linebreaks (Windows) 
 // ---------------------------------------
 void ReplaceCRLFCRtoCRLF( string& strSrc, string& strDest )
 {
    strDest  = boost::regex_replace ( strSrc, CRLFCRtoCRLF, "\\r\\n" );
 }

I was having this same issue for both Windows 8 and Windows Server 2012 configurations. I had installed the latest version of JDK Java 7 and had set my **JAVA_HOME**system env variable to the jre folder: *C:\Program Files (x86)\Java\jre7* I also added the bin folder to my **Path** system env variable: *%JAVA_HOME%\bin*

But I was still having problems with double clicking the executable jar files. I found another system env variable OPENDS_JAVA_ARGS that can be used to set the optional properties for javaw.exe. So I added this variable and set it to: -jar

Now I am able to run the executable jar files when double clicking them.

Some time ago I used JAD (JAva Decompiler) to achieve this - I do not think IntelliJ's decompiler was incorporated with exporting in mind. It is more of a tool to help look through classes where sources are not available.

JAD is still available for download, but I do not think anyone maintains it anymore: http://varaneckas.com/jad/

There were numerous plugins for it, namely Jadclipse (you guessed it, a way to use JAD in Eclipse - see decompiled classes where code is not available :)).

For dump, your DB fallow the below CMD

   mongodump -d <your d name> -o <dump path>
Ex:mongodump -d qualetics -o D:\dbpackup\qualetics

As of Angular 6.1, the router provides a configuration option called scrollPositionRestoration, this is designed to cater for this scenario.

imports: [
  RouterModule.forRoot(routes, {
    scrollPositionRestoration: 'enabled'
  }),
  ...
]

In order to use source map, you should change devtool option value from true to the value which available in this list, for instance source-map

devtool: 'source-map'

devtool: 'source-map' - A SourceMap is emitted.

With the introduction of globalThis in ES2020 you can use properties like.

For screen size:

globalThis.screen.availWidth 
globalThis.screen.availHeight

For Window Size

globalThis.outerWidth
globalThis.outerHeight

For Offset:

globalThis.pageXOffset
globalThis.pageYOffset

...& so on.

alert("Screen Width: "+ globalThis.screen.availWidth +"\nScreen Height: "+ globalThis.screen.availHeight)

If you are using Spring 3.2.x and <mvc:annotation-driven />, create this little BeanPostProcessor:

package spring;

public final class DoNotTruncateMyUrls implements BeanPostProcessor {
    @Override
    public Object postProcessBeforeInitialization(Object bean, String beanName) throws BeansException {
        if (bean instanceof RequestMappingHandlerMapping) {
            ((RequestMappingHandlerMapping)bean).setUseSuffixPatternMatch(false);
        }
        return bean;
    }
    @Override
    public Object postProcessAfterInitialization(Object bean, String beanName) throws BeansException {
        return bean;
    }
}

Then put this in your MVC config xml:

<bean class="spring.DoNotTruncateMyUrls" />

Since we're on a subject, one can use regular expressions too

"aaabcd".replaceFirst(".$",""); //=> aaabc  

from PIL import Image
import os, os.path

imgs = []
path = "/home/tony/pictures"
valid_images = [".jpg",".gif",".png",".tga"]
for f in os.listdir(path):
    ext = os.path.splitext(f)[1]
    if ext.lower() not in valid_images:
        continue
    imgs.append(Image.open(os.path.join(path,f)))
   

I had the same issue, couldn't find a right solution so I have manually deleted the component folder and then updated the app.module.ts file (removed the references to the deleted component) and it worked for me.

The W3C excluded such a selector because of the huge performance impact it would have on a browser.

Following is a summarization and curation from many different sources on this topic including code example and quotes from selected blog posts. The complete list of best practices can be found here

Best practices of Node.JS error handling

Number1: Use promises for async error handling

TL;DR: Handling async errors in callback style is probably the fastest way to hell (a.k.a the pyramid of doom). The best gift you can give to your code is using instead a reputable promise library which provides much compact and familiar code syntax like try-catch

Otherwise: Node.JS callback style, function(err, response), is a promising way to un-maintainable code due to the mix of error handling with casual code, excessive nesting and awkward coding patterns

Code example - good

doWork()
.then(doWork)
.then(doError)
.then(doWork)
.catch(errorHandler)
.then(verify);

code example anti pattern – callback style error handling

getData(someParameter, function(err, result){
    if(err != null)
      //do something like calling the given callback function and pass the error
    getMoreData(a, function(err, result){
          if(err != null)
            //do something like calling the given callback function and pass the error
        getMoreData(b, function(c){ 
                getMoreData(d, function(e){ 
                    ...
                });
            });
        });
    });
});

Blog quote: "We have a problem with promises" (From the blog pouchdb, ranked 11 for the keywords "Node Promises")

"…And in fact, callbacks do something even more sinister: they deprive us of the stack, which is something we usually take for granted in programming languages. Writing code without a stack is a lot like driving a car without a brake pedal: you don’t realize how badly you need it, until you reach for it and it’s not there. The whole point of promises is to give us back the language fundamentals we lost when we went async: return, throw, and the stack. But you have to know how to use promises correctly in order to take advantage of them."

Number2: Use only the built-in Error object

TL;DR: It pretty common to see code that throws errors as string or as a custom type – this complicates the error handling logic and the interoperability between modules. Whether you reject a promise, throw exception or emit error – using Node.JS built-in Error object increases uniformity and prevents loss of error information

Otherwise: When executing some module, being uncertain which type of errors come in return – makes it much harder to reason about the coming exception and handle it. Even worth, using custom types to describe errors might lead to loss of critical error information like the stack trace!

Code example - doing it right

    //throwing an Error from typical function, whether sync or async
 if(!productToAdd)
 throw new Error("How can I add new product when no value provided?");

//'throwing' an Error from EventEmitter
const myEmitter = new MyEmitter();
myEmitter.emit('error', new Error('whoops!'));

//'throwing' an Error from a Promise
 return new promise(function (resolve, reject) {
 DAL.getProduct(productToAdd.id).then((existingProduct) =>{
 if(existingProduct != null)
 return reject(new Error("Why fooling us and trying to add an existing product?"));

code example anti pattern

//throwing a String lacks any stack trace information and other important properties
if(!productToAdd)
    throw ("How can I add new product when no value provided?");

Blog quote: "A string is not an error" (From the blog devthought, ranked 6 for the keywords “Node.JS error object”)

"…passing a string instead of an error results in reduced interoperability between modules. It breaks contracts with APIs that might be performing instanceof Error checks, or that want to know more about the error. Error objects, as we’ll see, have very interesting properties in modern JavaScript engines besides holding the message passed to the constructor.."

Number3: Distinguish operational vs programmer errors

TL;DR: Operations errors (e.g. API received an invalid input) refer to known cases where the error impact is fully understood and can be handled thoughtfully. On the other hand, programmer error (e.g. trying to read undefined variable) refers to unknown code failures that dictate to gracefully restart the application

Otherwise: You may always restart the application when an error appear, but why letting ~5000 online users down because of a minor and predicted error (operational error)? the opposite is also not ideal – keeping the application up when unknown issue (programmer error) occurred might lead unpredicted behavior. Differentiating the two allows acting tactfully and applying a balanced approach based on the given context

Code example - doing it right

    //throwing an Error from typical function, whether sync or async
 if(!productToAdd)
 throw new Error("How can I add new product when no value provided?");

//'throwing' an Error from EventEmitter
const myEmitter = new MyEmitter();
myEmitter.emit('error', new Error('whoops!'));

//'throwing' an Error from a Promise
 return new promise(function (resolve, reject) {
 DAL.getProduct(productToAdd.id).then((existingProduct) =>{
 if(existingProduct != null)
 return reject(new Error("Why fooling us and trying to add an existing product?"));

code example - marking an error as operational (trusted)

//marking an error object as operational 
var myError = new Error("How can I add new product when no value provided?");
myError.isOperational = true;

//or if you're using some centralized error factory (see other examples at the bullet "Use only the built-in Error object")
function appError(commonType, description, isOperational) {
    Error.call(this);
    Error.captureStackTrace(this);
    this.commonType = commonType;
    this.description = description;
    this.isOperational = isOperational;
};

throw new appError(errorManagement.commonErrors.InvalidInput, "Describe here what happened", true);

//error handling code within middleware
process.on('uncaughtException', function(error) {
    if(!error.isOperational)
        process.exit(1);
});

Blog Quote: "Otherwise you risk the state" (From the blog debugable, ranked 3 for the keywords "Node.JS uncaught exception")

"…By the very nature of how throw works in JavaScript, there is almost never any way to safely “pick up where you left off”, without leaking references, or creating some other sort of undefined brittle state. The safest way to respond to a thrown error is to shut down the process. Of course, in a normal web server, you might have many connections open, and it is not reasonable to abruptly shut those down because an error was triggered by someone else. The better approach is to send an error response to the request that triggered the error, while letting the others finish in their normal time, and stop listening for new requests in that worker"

Number4: Handle errors centrally, through but not within middleware

TL;DR: Error handling logic such as mail to admin and logging should be encapsulated in a dedicated and centralized object that all end-points (e.g. Express middleware, cron jobs, unit-testing) call when an error comes in.

Otherwise: Not handling errors within a single place will lead to code duplication and probably to errors that are handled improperly

Code example - a typical error flow

//DAL layer, we don't handle errors here
DB.addDocument(newCustomer, (error, result) => {
    if (error)
        throw new Error("Great error explanation comes here", other useful parameters)
});

//API route code, we catch both sync and async errors and forward to the middleware
try {
    customerService.addNew(req.body).then(function (result) {
        res.status(200).json(result);
    }).catch((error) => {
        next(error)
    });
}
catch (error) {
    next(error);
}

//Error handling middleware, we delegate the handling to the centrzlied error handler
app.use(function (err, req, res, next) {
    errorHandler.handleError(err).then((isOperationalError) => {
        if (!isOperationalError)
            next(err);
    });
});

Blog quote: "Sometimes lower levels can’t do anything useful except propagate the error to their caller" (From the blog Joyent, ranked 1 for the keywords “Node.JS error handling”)

"…You may end up handling the same error at several levels of the stack. This happens when lower levels can’t do anything useful except propagate the error to their caller, which propagates the error to its caller, and so on. Often, only the top-level caller knows what the appropriate response is, whether that’s to retry the operation, report an error to the user, or something else. But that doesn’t mean you should try to report all errors to a single top-level callback, because that callback itself can’t know in what context the error occurred"

Number5: Document API errors using Swagger

TL;DR: Let your API callers know which errors might come in return so they can handle these thoughtfully without crashing. This is usually done with REST API documentation frameworks like Swagger

Otherwise: An API client might decide to crash and restart only because he received back an error he couldn’t understand. Note: the caller of your API might be you (very typical in a microservices environment)

Blog quote: "You have to tell your callers what errors can happen" (From the blog Joyent, ranked 1 for the keywords “Node.JS logging”)

…We’ve talked about how to handle errors, but when you’re writing a new function, how do you deliver errors to the code that called your function? …If you don’t know what errors can happen or don’t know what they mean, then your program cannot be correct except by accident. So if you’re writing a new function, you have to tell your callers what errors can happen and what they mea

Number6: Shut the process gracefully when a stranger comes to town

TL;DR: When an unknown error occurs (a developer error, see best practice number #3)- there is uncertainty about the application healthiness. A common practice suggests restarting the process carefully using a ‘restarter’ tool like Forever and PM2

Otherwise: When an unfamiliar exception is caught, some object might be in a faulty state (e.g an event emitter which is used globally and not firing events anymore due to some internal failure) and all future requests might fail or behave crazily

Code example - deciding whether to crash

//deciding whether to crash when an uncaught exception arrives
//Assuming developers mark known operational errors with error.isOperational=true, read best practice #3
process.on('uncaughtException', function(error) {
 errorManagement.handler.handleError(error);
 if(!errorManagement.handler.isTrustedError(error))
 process.exit(1)
});


//centralized error handler encapsulates error-handling related logic 
function errorHandler(){
 this.handleError = function (error) {
 return logger.logError(err).then(sendMailToAdminIfCritical).then(saveInOpsQueueIfCritical).then(determineIfOperationalError);
 }

 this.isTrustedError = function(error)
 {
 return error.isOperational;
 }

Blog quote: "There are three schools of thoughts on error handling" (From the blog jsrecipes)

…There are primarily three schools of thoughts on error handling: 1. Let the application crash and restart it. 2. Handle all possible errors and never crash. 3. Balanced approach between the two

Number7: Use a mature logger to increase errors visibility

TL;DR: A set of mature logging tools like Winston, Bunyan or Log4J, will speed-up error discovery and understanding. So forget about console.log.

Otherwise: Skimming through console.logs or manually through messy text file without querying tools or a decent log viewer might keep you busy at work until late

Code example - Winston logger in action

//your centralized logger object
var logger = new winston.Logger({
 level: 'info',
 transports: [
 new (winston.transports.Console)(),
 new (winston.transports.File)({ filename: 'somefile.log' })
 ]
 });

//custom code somewhere using the logger
logger.log('info', 'Test Log Message with some parameter %s', 'some parameter', { anything: 'This is metadata' });

Blog quote: "Lets identify a few requirements (for a logger):" (From the blog strongblog)

…Lets identify a few requirements (for a logger): 1. Time stamp each log line. This one is pretty self explanatory – you should be able to tell when each log entry occured. 2. Logging format should be easily digestible by humans as well as machines. 3. Allows for multiple configurable destination streams. For example, you might be writing trace logs to one file but when an error is encountered, write to the same file, then into error file and send an email at the same time…

Number8: Discover errors and downtime using APM products

TL;DR: Monitoring and performance products (a.k.a APM) proactively gauge your codebase or API so they can auto-magically highlight errors, crashes and slow parts that you were missing

Otherwise: You might spend great effort on measuring API performance and downtimes, probably you’ll never be aware which are your slowest code parts under real world scenario and how these affects the UX

Blog quote: "APM products segments" (From the blog Yoni Goldberg)

"…APM products constitutes 3 major segments:1. Website or API monitoring – external services that constantly monitor uptime and performance via HTTP requests. Can be setup in few minutes. Following are few selected contenders: Pingdom, Uptime Robot, and New Relic 2. Code instrumentation – products family which require to embed an agent within the application to benefit feature slow code detection, exceptions statistics, performance monitoring and many more. Following are few selected contenders: New Relic, App Dynamics 3. Operational intelligence dashboard – these line of products are focused on facilitating the ops team with metrics and curated content that helps to easily stay on top of application performance. This is usually involves aggregating multiple sources of information (application logs, DB logs, servers log, etc) and upfront dashboard design work. Following are few selected contenders: Datadog, Splunk"

The above is a shortened version - see here more best practices and examples

The most beginner-friendly solution is:

Drag a Timer from the Toolbox, give it a Name, set your desired Interval, and set "Enabled" to True. Then double-click the Timer and Visual Studio (or whatever you are using) will write the following code for you:

private void wait_Tick(object sender, EventArgs e)
{
    refreshText(); // Add the method you want to call here.
}

No need to worry about pasting it into the wrong code block or something like that.

When it comes to multi field forms, it makes sense to use React's key feature: components.

In my projects, I create TextField components, that take a value prop at minimum, and it takes care of handling common behaviors of an input text field. This way you don't have to worry about keeping track of field names when updating the value state.

[...]

handleChange: function(event) {
  this.setState({value: event.target.value});
},
render: function() {
  var value = this.state.value;
  return <input type="text" value={value} onChange={this.handleChange} />;
}

[...]

Sounds like you only installed the MySQL Client Tools (MySQL Workbench). You have to install the MySQL Database server, configure and start it.

You probably want the MySQL Community Server download.

In case you are trying to build a jar with kotlin you need to create a src/main/java folder and use this folder as a location for the META-INF folder.

  SELECT * FROM (SELECT ROW_NUMBER () OVER (ORDER BY sal DESC) row_number, sr,sal FROM empsal) a WHERE (row_number%2) = 1

and

      SELECT * FROM (SELECT ROW_NUMBER () OVER (ORDER BY sal DESC) row_number, sr,sal FROM   empsal) a WHERE (row_number%2) = 0

Yes, you can use GROUP BY:

SELECT time,
       activities,
       COUNT(*)
FROM table
GROUP BY time, activities;

For Mountain Lion, Apple's java is up to 1.6.0_35-b10-428.jdk as of today.
It is indeed located under /Library/Java/JavaVirtualMachines .

You just download
"Java for OS X 2012-005 Developer Package" (Sept 6, 2012)
from
http://connect.apple.com/

In my view, Apple's naming is at least a bit confusing; why "-005" - is this the fifth version, or the fifth of five installers one needs?

And then run the installer; then follow the above steps inside Eclipse.

The simple solution would be:

while True:
    age = int(input("Please enter your age: "))

    if (age<=0) or (age>120):
        print('Sorry, I did not understand that.Please try again')
        continue
    else:

        if age>=18:
            print("You are able to vote in the United States!")
        else:
            print("You are not able to vote in the United States.")
        break

Explanation of above code: In order for a valid age,it should be positive and should not be more than normal physical age,say for example maximum age is 120.

Then we can ask user for age and if age input is negative or more than 120,we consider it invalid input and ask the user to try again.

Once the valid input is entered, we perform a check (using nested if-else statement) whether the age is >=18 or vice versa and print a message whether the user is eligible to vote

http://github.com/grosser/single_test lets you do stuff like..

rake spec:user          #run spec/model/user_spec.rb (searches for user*_spec.rb)
rake test:users_c       #run test/functional/users_controller_test.rb
rake spec:user:token    #run the first spec in user_spec.rb that matches /token/
rake test:user:token    #run all tests in user_test.rb that match /token/
rake test:last
rake spec:last

'[{"event":"inbound","ts":1426249238}]' is a string, you cannot access any properties there. You will have to parse it to an object, with JSON.parse() and then handle it like a normal object

I needed to add USE_FRM to the repair statement to make it work.

REPAIR TABLE <table_name> USE_FRM;

Turning my linux environment into a clean complete UTF-8 environment made the trick for me. Try the following in your command line:

export LC_ALL=en_US.UTF-8
export LANG=en_US.UTF-8
export LANGUAGE=en_US.UTF-8

Remove the function and check the output of:

var_dump(function_exists('parseDate'));

In which case, change the name of the function.

If you get false, you're including the file with that function twice, replace :

include

by

include_once

And replace :

require

by

require_once

EDIT : I'm just a little too late, post before beat me to it !

You can use Procpath (author here), to simplify parsing of VmSwap from /proc/$PID/status.

$ procpath record -f stat,cmdline,status -r 1 -d db.sqlite
$ sqlite3 -column db.sqlite \
  'SELECT status_name, status_vmswap FROM record ORDER BY status_vmswap DESC LIMIT 5'
Web Content  192136       
okular       186872       
thunderbird  183692       
Web Content  143404       
MainThread   86300

You can also plot VmSwap of processes of interest over time like this. Here I'm recording my Firefox process tree while opening a couple tens of tabs along with statrting a memory-hungry application to try to cause it to swap (which wasn't convincing for Firefox, but your kilometrage may vary).

$ procpath record -f stat,cmdline,status -i 1 -d db2.sqlite \
  '$..children[?(@.stat.pid == 6029)]'
# interrupt by Ctrl+C
$ procpath plot -d db2.sqlite -q cpu --custom-value-expr status_vmswap \
  --title "CPU usage, % vs Swap, kB"

For a system with legacy usb coming back and libusb-1.0, this approach will work to retrieve the various actual strings. I show the vendor and product as examples. It can cause some I/O, because it actually reads the info from the device (at least the first time, anyway.) Some devices don't provide this information, so the presumption that they do will throw an exception in that case; that's ok, so we pass.

import usb.core
import usb.backend.libusb1

busses = usb.busses()
for bus in busses:
    devices = bus.devices
    for dev in devices:
        if dev != None:
            try:
                xdev = usb.core.find(idVendor=dev.idVendor, idProduct=dev.idProduct)
                if xdev._manufacturer is None:
                    xdev._manufacturer = usb.util.get_string(xdev, xdev.iManufacturer)
                if xdev._product is None:
                    xdev._product = usb.util.get_string(xdev, xdev.iProduct)
                stx = '%6d %6d: '+str(xdev._manufacturer).strip()+' = '+str(xdev._product).strip()
                print stx % (dev.idVendor,dev.idProduct)
            except:
                pass

>>> {i:i for i in range(1, 11)}
{1: 1, 2: 2, 3: 3, 4: 4, 5: 5, 6: 6, 7: 7, 8: 8, 9: 9, 10: 10}

First make sure you have installed the composer.

composer install

If you already have installed then update the composer.

composer update

if there are multiple java processes and you wish to kill them with one command try the below command

kill -9 $(ps -ef | pgrep -f "java")

replace "java" with any process string identifier , to kill anything else.

Use the javac program that comes with the JDK (visit java.sun.com if you don't have it). The installer does not automatically add javac to your system path, so you'll need to add the bin directory of the installed path to your system path before you can use it easily.

Just in case you are looking for an alternate way and the environment you use is Windows, Microsoft's Network Monitor 3.3 is a good choice. It has the process name column. You easily add it to a filter using the context menu and apply the filter.. As usual the GUI is very intuitive...

In MYSQL we have function called DATE_FORMAT(date,format). In your case your select statement will become like this:-

SELECT DATE_FORMAT(dateTimeFieldName,"%a%m%Y") as dateFieldName FROM table_name

A workaround wich works perfectly :

In the source page,, start opening a session and assign as many values as you might want. Then do the relocation with "header" :

<!DOCTYPE html>
<html>
   <head>
       <?php
           session_start();
           $_SESSION['val1'] = val1;
           ...
           $_SESSION['valn'] = valn;
           header('Location: http//Page-to-redirect-to');
       ?>
   </head>
</html>

And then, in the targe page :

<!DOCTYPE html>
<?php
    session_start();
?>
<html>
    ...
    <body>
        <?php
            if (isset($_SESSION['val1']) && ... && isset($_SESSION['valn'])) {
                YOUR CODE HERE based on $_SESSION['val1']...$_SESSION['valn'] values
            }
        ?>
    </body>
</html>

No need of Javascript nor JQuery.. Good luck !

Windows 7, 64 bit, no modifications to the Registry key, the location is:

I create the database myself using the command line. Then try to import again, it works.

You could use TimeZoneInfo class

The TimeZone class recognizes local time zone, and can convert times between Coordinated Universal Time (UTC) and local time. A TimeZoneInfo object can represent any time zone, and methods of the TimeZoneInfo class can be used to convert the time in one time zone to the corresponding time in any other time zone. The members of the TimeZoneInfo class support the following operations:

1. Retrieving a time zone that is already defined by the operating system.

2. Enumerating the time zones that are available on a system.

3. Converting times between different time zones.

4. Creating a new time zone that is not already defined by the operating system.

   Serializing a time zone for later retrieval.

To only modify the title's font (and not the font of the axis) I used this:

import matplotlib.pyplot as plt
fig = plt.Figure()
ax = fig.add_subplot(111)
ax.set_title('My Title', fontdict={'fontsize': 8, 'fontweight': 'medium'})

The fontdict accepts all kwargs from matplotlib.text.Text.

You may already have Process Explorer (from Sysinternals, now part of Microsoft) installed. If not, go ahead and install it now -- it's just that cool.

In Process Explorer: locate the process in question, right-click and select the TCP/IP tab. It will even show you, for each socket, a stack trace representing the code that opened that socket.

A primary key is not required. A foreign key is not required either. You can construct a query joining two tables on any column you wish as long as the datatypes either match or are converted to match. No relationship needs to explicitly exist.

To do this you use an outer join:

select tablea.code, tablea.name, tableb.location from tablea left outer join 
tableb on tablea.code = tableb.code

join with out relation

SQL join

I experienced the same error and tried numerous things before I succeeded. The solution was to prepend the path of the script to the relative path of the module like this:

// Note that .Path will only be available during script-execution
$ScriptPath = Split-Path $MyInvocation.MyCommand.Path

Import-Module $ScriptPath\Modules\Builder.psm1

Btw you should take a look at http://msdn.microsoft.com/en-us/library/dd878284(v=vs.85).aspx which states:

Beginning in Windows PowerShell 3.0, modules are imported automatically when any cmdlet or function in the module is used in a command. This feature works on any module in a directory that this included in the value of the PSModulePath environment variable ($env:PSModulePath)

From man curl:

-x, --proxy <[protocol://][user:password@]proxyhost[:port]>

     Use the specified HTTP proxy. 
     If the port number is not specified, it is assumed at port 1080.

General way:

export http_proxy=http://your.proxy.server:port/

Then you can connect through proxy from (many) application.

And, as per comment below, for https:

export https_proxy=https://your.proxy.server:port/

The only suspect entry in your config looks to me to be core.ignorecase. You could try unsetting that with:

  git config --unset core.ignorecase

... and see if the output from git status or git diff is different.

1) First you need to generate EDMX model using your database. To do that you should add new item to your project:

• Select ADO.NET Entity Data Model from the Templates list.
• On the Choose Model Contents page, select the Generate from Database option and click Next.
• Choose your database.
• On the Choose Your Database Objects page, check the Tables. Choose Views or Stored Procedures if you need.

So now you have Model1.edmx file in your project.

2) To generate classes using your model:

• Open your EDMX model designer.
• On the design surface Right Click –> Add Code Generation Item…
• Select Online templates.
• Select EF 4.x DbContext Generator for C#.
• Click ‘Add’.

Notice that two items are added to your project:

• Model1.tt (This template generates very simple POCO classes for each entity in your model)
• Model1.Context.tt (This template generates a derived DbContext to use for querying and persisting data)

3) Read/Write Data example:

 var dbContext = new YourModelClass(); //class derived from DbContext
 var contacts = from c in dbContext.Contacts select c; //read data
 contacts.FirstOrDefault().FirstName = "Alex"; //edit data
 dbContext.SaveChanges(); //save data to DB

Don't forget that you need 4.x version of EntityFramework. You can download EF 4.1 here: Entity Framework 4.1.

Please do right click on the project and go to properties. Then go to Build and Packaging. You can see the JAR file location that is produced by defualt setting of netbean in the dist directory.

Simple Example: Let's say you have a Students table, and a Lockers table. In SQL, the first table you specify in a join, Students, is the LEFT table, and the second one, Lockers, is the RIGHT table.

Each student can be assigned to a locker, so there is a LockerNumber column in the Student table. More than one student could potentially be in a single locker, but especially at the beginning of the school year, you may have some incoming students without lockers and some lockers that have no students assigned.

For the sake of this example, let's say you have 100 students, 70 of which have lockers. You have a total of 50 lockers, 40 of which have at least 1 student and 10 lockers have no student.

INNER JOIN is equivalent to "show me all students with lockers".
Any students without lockers, or any lockers without students are missing.
Returns 70 rows

LEFT OUTER JOIN would be "show me all students, with their corresponding locker if they have one".
This might be a general student list, or could be used to identify students with no locker.
Returns 100 rows

RIGHT OUTER JOIN would be "show me all lockers, and the students assigned to them if there are any".
This could be used to identify lockers that have no students assigned, or lockers that have too many students.
Returns 80 rows (list of 70 students in the 40 lockers, plus the 10 lockers with no student)

FULL OUTER JOIN would be silly and probably not much use.
Something like "show me all students and all lockers, and match them up where you can"
Returns 110 rows (all 100 students, including those without lockers. Plus the 10 lockers with no student)

CROSS JOIN is also fairly silly in this scenario.
It doesn't use the linked lockernumber field in the students table, so you basically end up with a big giant list of every possible student-to-locker pairing, whether or not it actually exists.
Returns 5000 rows (100 students x 50 lockers). Could be useful (with filtering) as a starting point to match up the new students with the empty lockers.

Look at http.request

var options = {
  host: url,
  port: 80,
  path: '/resource?id=foo&bar=baz',
  method: 'POST'
};

http.request(options, function(res) {
  console.log('STATUS: ' + res.statusCode);
  console.log('HEADERS: ' + JSON.stringify(res.headers));
  res.setEncoding('utf8');
  res.on('data', function (chunk) {
    console.log('BODY: ' + chunk);
  });
}).end();

I had the same problem and for some reason The sshKeys was not syncing up with my user on the instance.

I created another user by adding --ssh_user=anotheruser to gcutil command.

The gcutil looked like this

gcutil --service_version="v1" --project="project"  --ssh_user=anotheruser ssh  --zone="us-central1-a" "inst1"

Check whether you are actually under a github repo.

So, listing of .git/ should give you results..otherwise you may be some level outside your repo.

Now, cd to your repo and you are good to go.

This works for me, in MVC5:

@Html.TextBoxFor(m => m.Name, new { @class = "form-control", id = "theID" , @Value="test" })

Is there a function in the .net Math library?

No.

It's not hard to write your own though. The naive algorithm sorts the array and picks the middle (or the average of the two middle) elements. However, this algorithm is O(n log n) while its possible to solve this problem in O(n) time. You want to look at selection algorithms to get such an algorithm.

Perl approach:

perl -ne 'if($i<1000) { print; } else { print STDERR;}; $i++;' in 1> in.new 2> out && mv in.new in

I guess this is because your nodejs cert has expired. Type this line :
npm set registry http://registry.npmjs.org/
and after that try again with npm install . This actually solved my problem.

Add this:

<div class="footer navbar-fixed-bottom">

EDIT: class navbar-fixed-bottom has been changed to fixed-bottom as of Bootstrap v4-alpha.6.

Try this:

SELECT
    'the sqlserver is ' + substring(@@VERSION, 21, 5) AS [sql version]

I had to read subtitles files and split them into sentences. After pre-processing (like removing time information etc in the .srt files), the variable fullFile contained the full text of the subtitle file. The below crude way neatly split them into sentences. Probably I was lucky that the sentences always ended (correctly) with a space. Try this first and if it has any exceptions, add more checks and balances.

# Very approximate way to split the text into sentences - Break after ? . and !
fullFile = re.sub("(\!|\?|\.) ","\\1<BRK>",fullFile)
sentences = fullFile.split("<BRK>");
sentFile = open("./sentences.out", "w+");
for line in sentences:
    sentFile.write (line);
    sentFile.write ("\n");
sentFile.close;

Oh! well. I now realize that since my content was Spanish, I did not have the issues of dealing with "Mr. Smith" etc. Still, if someone wants a quick and dirty parser...
