Install rbenv or rvm as your Ruby version manager (I prefer rbenv) via homebrew (ie. brew update & brew install rbenv) but then for example in rbenv's case make sure to add rbenv to your $PATH as instructed here and here.

For a deeper explanation on how rbenv works I recommend this.

I found out this was the easiest way to get access to the clipboard from python:

1) Install pyperclip: pip install pyperclip

2) Usage:

import pyperclip

s = pyperclip.paste()
pyperclip.copy(s)

# the type of s is string

Tested on Win10 64-bit, Python 3.5 and Python 3.7.3 (64-bit). Seems to work with non-ASCII characters, too. Tested characters include ±°©©aß????Fåäö

Update, if you are running SQL Server 2012 see: https://stackoverflow.com/a/10309947

The problem is that the SQL Server implementation of the Over clause is somewhat limited.

Oracle (and ANSI-SQL) allow you to do things like:

 SELECT somedate, somevalue,
  SUM(somevalue) OVER(ORDER BY somedate 
     ROWS BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW) 
          AS RunningTotal
  FROM Table

SQL Server gives you no clean solution to this problem. My gut is telling me that this is one of those rare cases where a cursor is the fastest, though I will have to do some benchmarking on big results.

The update trick is handy but I feel its fairly fragile. It seems that if you are updating a full table then it will proceed in the order of the primary key. So if you set your date as a primary key ascending you will probably be safe. But you are relying on an undocumented SQL Server implementation detail (also if the query ends up being performed by two procs I wonder what will happen, see: MAXDOP):

Full working sample:

drop table #t 
create table #t ( ord int primary key, total int, running_total int)

insert #t(ord,total)  values (2,20)
-- notice the malicious re-ordering 
insert #t(ord,total) values (1,10)
insert #t(ord,total)  values (3,10)
insert #t(ord,total)  values (4,1)

declare @total int 
set @total = 0
update #t set running_total = @total, @total = @total + total 

select * from #t
order by ord 

ord         total       running_total
----------- ----------- -------------
1           10          10
2           20          30
3           10          40
4           1           41

You asked for a benchmark this is the lowdown.

The fastest SAFE way of doing this would be the Cursor, it is an order of magnitude faster than the correlated sub-query of cross-join.

The absolute fastest way is the UPDATE trick. My only concern with it is that I am not certain that under all circumstances the update will proceed in a linear way. There is nothing in the query that explicitly says so.

Bottom line, for production code I would go with the cursor.

Test data:

create table #t ( ord int primary key, total int, running_total int)

set nocount on 
declare @i int
set @i = 0 
begin tran
while @i < 10000
begin
   insert #t (ord, total) values (@i,  rand() * 100) 
    set @i = @i +1

Update (2017)

Here in 2017, Promises are built into JavaScript, they were added by the ES2015 spec (polyfills are available for outdated environments like IE8-IE11). The syntax they went with uses a callback you pass into the Promise constructor (the Promise executor) which receives the functions for resolving/rejecting the promise as arguments.

First, since async now has a meaning in JavaScript (even though it's only a keyword in certain contexts), I'm going to use later as the name of the function to avoid confusion.

Basic Delay

Using native promises (or a faithful polyfill) it would look like this:

function later(delay) {
    return new Promise(function(resolve) {
        setTimeout(resolve, delay);
    });
}

Note that that assumes a version of setTimeout that's compliant with the definition for browsers where setTimeout doesn't pass any arguments to the callback unless you give them after the interval (this may not be true in non-browser environments, and didn't used to be true on Firefox, but is now; it's true on Chrome and even back on IE8).

Basic Delay with Value

If you want your function to optionally pass a resolution value, on any vaguely-modern browser that allows you to give extra arguments to setTimeout after the delay and then passes those to the callback when called, you can do this (current Firefox and Chrome; IE11+, presumably Edge; not IE8 or IE9, no idea about IE10):

function later(delay, value) {
    return new Promise(function(resolve) {
        setTimeout(resolve, delay, value); // Note the order, `delay` before `value`
        /* Or for outdated browsers that don't support doing that:
        setTimeout(function() {
            resolve(value);
        }, delay);
        Or alternately:
        setTimeout(resolve.bind(null, value), delay);
        */
    });
}

If you're using ES2015+ arrow functions, that can be more concise:

function later(delay, value) {
    return new Promise(resolve => setTimeout(resolve, delay, value));
}

or even

const later = (delay, value) =>
    new Promise(resolve => setTimeout(resolve, delay, value));

Cancellable Delay with Value

If you want to make it possible to cancel the timeout, you can't just return a promise from later, because promises can't be cancelled.

But we can easily return an object with a cancel method and an accessor for the promise, and reject the promise on cancel:

const later = (delay, value) => {
    let timer = 0;
    let reject = null;
    const promise = new Promise((resolve, _reject) => {
        reject = _reject;
        timer = setTimeout(resolve, delay, value);
    });
    return {
        get promise() { return promise; },
        cancel() {
            if (timer) {
                clearTimeout(timer);
                timer = 0;
                reject();
                reject = null;
            }
        }
    };
};

Live Example:

const later = (delay, value) => {_x000D_
    let timer = 0;_x000D_
    let reject = null;_x000D_
    const promise = new Promise((resolve, _reject) => {_x000D_

Original Answer from 2014

Usually you'll have a promise library (one you write yourself, or one of the several out there). That library will usually have an object that you can create and later "resolve," and that object will have a "promise" you can get from it.

Then later would tend to look something like this:

function later() {
    var p = new PromiseThingy();
    setTimeout(function() {
        p.resolve();
    }, 2000);

    return p.promise(); // Note we're not returning `p` directly
}

In a comment on the question, I asked:

Are you trying to create your own promise library?

and you said

I wasn't but I guess now that's actually what I was trying to understand. That how a library would do it

To aid that understanding, here's a very very basic example, which isn't remotely Promises-A compliant: Live Copy

      var PromiseThingy = (function() {

        // Internal - trigger a callback
        function triggerCallback(callback, promise) {
          try {
            callback(promise.resolvedValue);
          }
          catch (e) {
          }
        }

        // The internal promise constructor, we don't share this
        function Promise() {
          this.callbacks = [];
        }

        // Register a 'then' callback
        Promise.prototype.then = function(callback) {
          var thispromise = this;

          if (!this.resolved) {
            // Not resolved yet, remember the callback
            this.callbacks.push(callback);
          }
          else {
            // Resolved; trigger callback right away, but always async
            setTimeout(function() {
              triggerCallback(callback, thispromise);
            }, 0);
          }
          return this;

          var n;

          if (!this.p.resolved) {
            this.p.resolved = true;
            this.p.resolvedValue = value;
            for (n = 0; n < this.p.callbacks.length; ++n) {
              triggerCallback(this.p.callbacks[n], this.p);
            }
          }
        };

        // Get our underlying promise
        PromiseThingy.prototype.promise = function() {
          return this.p;
        };

        // Export public
        return PromiseThingy;
      })();

      // ==== Using it

      function later() {
        var p = new PromiseThingy();
        setTimeout(function() {
          p.resolve();

        return p.promise(); // Note we're not returning `p` directly

      });

      function display(msg) {
        var p = document.createElement('p');

            $('#MyIdTextBox').val(ui.item.id);
            return ui.item.label;
        }
    });
});

The above responses helped but, did not work in my implementation. The instead of using setting the value using jQuery, I am returning the value from the function to the select option.

The MyDataFactory.ashx page has a class with three properties Id, Label, Value.

Pass the List into the JavaScript serializer, and return the response.

This works with jQuery UI v1.10.3

$("selector").dialog({height:'auto', width:'auto'});

In my case, the same error was caused because colon: was missing at end as in staging.deploy:. So note that it can be easy syntax mistake.

This is my working solution:

select tabname as table_name
from syscat.tables
where tabschema = 'schema_name' -- put schema name here
      and type = 'T'
order by tabname

You just have to use class="row-eq-height" with your class="row" to get equal height columns for previous bootstrap versions.

but with bootstrap 4 this comes natively.

check this link --http://getbootstrap.com.vn/examples/equal-height-columns/

Try this out

/**
  * Checks the string if undefined, null, not typeof string, empty or space(s)
  * @param {any} str string to be evaluated
  * @returns {boolean} the evaluated result
*/
function isStringNullOrWhiteSpace(str) {
    return str === undefined || str === null
                             || typeof str !== 'string'
                             || str.match(/^ *$/) !== null;
}

You can use it like this

isStringNullOrWhiteSpace('Your String');

In the Edge browser as of build 20.10240.16384.0 you can hide the address bar by setting location=no in the window.open features.

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

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

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

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

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

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

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

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

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

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

As far as I know python will compile all modules you "import". However python will NOT compile a python script run using: "python script.py" (it will however compile any modules that the script imports).

The real questions is why you don't want python to compile the modules? You could probably automate a way of cleaning these up if they are getting in the way.

Use ViewBag

ViewBag.MyString = "some string";
return View();

In your View

<h1>@ViewBag.MyString</h1>

I wanted to remotely watch a yum upgrade process that had been run locally, so while there were probably more efficient ways to do this, here's what I did:

watch cat /dev/vcsa1

Obviously you'd want to use vcsa2, vcsa3, etc., depending on which terminal was being used.

So long as my terminal window was of the same width as the terminal that the command was being run on, I could see a snapshot of their current output every two seconds. The other commands recommended elsewhere did not work particularly well for my situation, but that one did the trick.

You can subclass HandleErrorAttribute and override its OnException member (no need to copy) so that it logs the exception with ELMAH and only if the base implementation handles it. The minimal amount of code you need is as follows:

using System.Web.Mvc;
using Elmah;

public class HandleErrorAttribute : System.Web.Mvc.HandleErrorAttribute
{
    public override void OnException(ExceptionContext context)
    {
        base.OnException(context);
        if (!context.ExceptionHandled) 
            return;
        var httpContext = context.HttpContext.ApplicationInstance.Context;
        var signal = ErrorSignal.FromContext(httpContext);
        signal.Raise(context.Exception, httpContext);
    }
}

The base implementation is invoked first, giving it a chance to mark the exception as being handled. Only then is the exception signaled. The above code is simple and may cause issues if used in an environment where the HttpContext may not be available, such as testing. As a result, you will want code that is that is more defensive (at the cost of being slightly longer):

using System.Web;
using System.Web.Mvc;
using Elmah;

public class HandleErrorAttribute : System.Web.Mvc.HandleErrorAttribute
{
    public override void OnException(ExceptionContext context)
    {
        base.OnException(context);
        if (!context.ExceptionHandled       // if unhandled, will be logged anyhow
            || TryRaiseErrorSignal(context) // prefer signaling, if possible
            || IsFiltered(context))         // filtered?
            return;

        LogException(context);
    }

    private static bool TryRaiseErrorSignal(ExceptionContext context)
    {
        var httpContext = GetHttpContextImpl(context.HttpContext);
        if (httpContext == null)
            return false;
        var signal = ErrorSignal.FromContext(httpContext);
        if (signal == null)
            return false;
        signal.Raise(context.Exception, httpContext);
        return true;
    }

    private static bool IsFiltered(ExceptionContext context)
    {
        var config = context.HttpContext.GetSection("elmah/errorFilter")
                        as ErrorFilterConfiguration;

        if (config == null)
            return false;

        var testContext = new ErrorFilterModule.AssertionHelperContext(
                              context.Exception, 
                              GetHttpContextImpl(context.HttpContext));
        return config.Assertion.Test(testContext);
    }

    private static void LogException(ExceptionContext context)
    {
        var httpContext = GetHttpContextImpl(context.HttpContext);
        var error = new Error(context.Exception, httpContext);
        ErrorLog.GetDefault(httpContext).Log(error);
    }

    private static HttpContext GetHttpContextImpl(HttpContextBase context)
    {
        return context.ApplicationInstance.Context;
    }
}

This second version will try to use error signaling from ELMAH first, which involves the fully configured pipeline like logging, mailing, filtering and what have you. Failing that, it attempts to see whether the error should be filtered. If not, the error is simply logged. This implementation does not handle mail notifications. If the exception can be signaled then a mail will be sent if configured to do so.

You may also have to take care that if multiple HandleErrorAttribute instances are in effect then duplicate logging does not occur, but the above two examples should get your started.

Update to a specific revision:

svn up -r1234 file

You can pass via GET. So if you want to pass the value foobar from PageA.php to PageB.php, call it as PageB.php?value=foobar.

In PageB.php, you can access it this way:

$value = $_GET['value'];

If you use the absence of "Mobile" then its almost correct. But there are HTC Sensation 4G (4.3 inch with android 2.X) which does not send Mobile keyword.

The reason why you may want to treat it separately is due to iframes etc.

If data frame fits in a driver memory and you want to save to local files system you can convert Spark DataFrame to local Pandas DataFrame using toPandas method and then simply use to_csv:

df.toPandas().to_csv('mycsv.csv')

Otherwise you can use spark-csv:

• Spark 1.3

  df.save('mycsv.csv', 'com.databricks.spark.csv')
  

• Spark 1.4+

  df.write.format('com.databricks.spark.csv').save('mycsv.csv')
  

In Spark 2.0+ you can use csv data source directly:

df.write.csv('mycsv.csv')

>>> print int('01010101111',2)
687
>>> print int('11111111',2)

                if (textRange.Text.Trim().Equals("Place Holder"))
                {
                    ((RichTextBox)sender).Foreground = Brushes.Black;

        private void rtb_LostKeyboardFocus(object sender, KeyboardFocusChangedEventArgs e)
        {
            //Make sure sender is the correct Control.
            if (sender is RichTextBox)
            {
                //If nothing was entered, reset default text.
                TextRange textRange = new TextRange(richTextBox1.Document.ContentStart, richTextBox1.Document.ContentEnd); 

                if (textRange.Text.Trim().Equals(""))
                {
                    ((RichTextBox)sender).Foreground = Brushes.Gray;
                    ((RichTextBox)sender).AppendText("Place Holder");
                }
            }
        }
}

At least in Xcode 5, there is a simple and pretty good (not perfect) solution. In IB, drag a Bar Button Item off the Utilities pane and drop it on the left side of the Navigation Bar where the Back button would be. Set the label to "Back." You will have a functioning button that you can tie to your IBAction and close your viewController. I'm doing some work and then triggering an unwind segue and it works perfectly.

What isn't ideal is that this button does not get the < arrow and does not carry forward the previous VCs title, but I think this can be managed. For my purposes, I set the new Back button to be a "Done" button so it's purpose is clear.

You also end up with two Back buttons in the IB navigator, but it is easy enough to label it for clarity.

The only reason to have a return in a void function would be to exit early due to some conditional statement:

void foo(int y)
{
    if(y == 0) return;

    // do stuff with y
}

As unwind said: when the code ends, it ends. No need for an explicit return at the end.

I managed to copy text to the clipboard (without showing any text boxes) by adding a hidden input element to body, i.e.:

 function copy(txt){_x000D_
  var cb = document.getElementById("cb");_x000D_
  cb.value = txt;_x000D_
  cb.style.display='block';_x000D_
  cb.select();_x000D_
  document.execCommand('copy');_x000D_
  cb.style.display='none';_x000D_
 }

<button onclick="copy('Hello Clipboard!')"> copy </button>_x000D_
<input id="cb" type="text" hidden>

another option (in place, any combination of indices):

_marker = object()

for i in indices:
    my_list[i] = _marker  # marked for deletion

obj[:] = [v for v in my_list if v is not _marker]

The first constructor in the header should not end with a semicolon. #include <string> is missing in the header. string is not qualified with std:: in the .cpp file. Those are all simple syntax errors. More importantly: you are not using references, when you should. Also the way you use the ifstream is broken. I suggest learning C++ before trying to use it.

Let's fix this up:

//polygone.h
# if !defined(__POLYGONE_H__)
# define __POLYGONE_H__

#include <iostream>
#include <string>    

class Polygone {
public:
  // declarations have to end with a semicolon, definitions do not
  Polygone(){} // why would we needs this?
  Polygone(const std::string& fichier);
};

# endif

and

//polygone.cc
// no need to include things twice
#include "polygone.h"
#include <fstream>


Polygone::Polygone(const std::string& nom)
{
  std::ifstream fichier (nom, ios::in);


  if (fichier.is_open())
  {
    // keep the scope as tiny as possible
    std::string line;
    // getline returns the stream and streams convert to booleans
    while ( std::getline(fichier, line) )
    {
      std::cout << line << std::endl;
    }
  }
  else
  {
    std::cerr << "Erreur a l'ouverture du fichier" << std::endl;
  }
}

There are multiple hardware revisions of Nexus 5. So, the accepted answer doesn't work for all devices (it didn't work for me).

1. Open Device Manager, right click and Properties. Now go to the "Details" tab And now select the property "Hardware Ids". Note down the PID and VID.

2. Download the Google driver

3. Update the android_winusb.inf with above VID and PID

   %CompositeAdbInterface% = USB_Install, USB\VID_18D1&**PID_4EE1**
   

4. Now in Device Manager, find Nexus 5, and update the driver software, and browse to the location where you downloaded.

5. The driver should be installed, and you should be see the device in ADB.

Very simply said, new X is Object.create(X.prototype) with additionally running the constructor function. (And giving the constructor the chance to return the actual object that should be the result of the expression instead of this.)

That’s it. :)

The rest of the answers are just confusing, because apparently nobody else reads the definition of new either. ;)

Here is a nice macro that will work for either NSMutableArray OR NSArray:

#define reverseArray(__theArray) {\
    if ([__theArray isKindOfClass:[NSMutableArray class]]) {\
        if ([(NSMutableArray *)__theArray count] > 1) {\
            NSUInteger i = 0;\
            NSUInteger j = [(NSMutableArray *)__theArray count]-1;\
            while (i < j) {\
                [(NSMutableArray *)__theArray exchangeObjectAtIndex:i\
                                                withObjectAtIndex:j];\
                i++;\
                j--;\
            }\
        }\
    } else if ([__theArray isKindOfClass:[NSArray class]]) {\
        __theArray = [[NSArray alloc] initWithArray:[[(NSArray *)__theArray reverseObjectEnumerator] allObjects]];\
    }\
}

To use just call: reverseArray(myArray);

On most devices, the other answers work. For me, to ensure it worked on every device (in react) I had to wrap it in an anchor tag <a> and add the following: :hover, :focus, :active (in that order), as well as role="button" and tabIndex="0".

Hi if you are having dropdownlist like this

<select id="testID">
<option value="1">Value1</option>
<option value="2">Value2</option>
<option value="3">Value3</option>
<option value="4">Value4</option>
<option value="5">Value5</option>
<option value="6">Value6</option>
</select>
<input type="button" value="Get dropdown selected Value" onclick="getHTML();">

after giving id to dropdownlist you just need to add jquery code like this

function getHTML()
{
      var display=$('#testID option:selected').html();
      alert(display);
}

First of all, remove video's "controls" attribute.
For iOS, we could hide video's buildin play button by adding the following CSS pseudo selector:

video::-webkit-media-controls-start-playback-button {
    display: none;
}

I think there are three key items you need to understand regarding project structure: Targets, projects, and workspaces. Targets specify in detail how a product/binary (i.e., an application or library) is built. They include build settings, such as compiler and linker flags, and they define which files (source code and resources) actually belong to a product. When you build/run, you always select one specific target.

It is likely that you have a few targets that share code and resources. These different targets can be slightly different versions of an app (iPad/iPhone, different brandings,…) or test cases that naturally need to access the same source files as the app. All these related targets can be grouped in a project. While the project contains the files from all its targets, each target picks its own subset of relevant files. The same goes for build settings: You can define default project-wide settings in the project, but if one of your targets needs different settings, you can always override them there:

Shared project settings that all targets inherit, unless they override it

Concrete target settings: PSE iPhone overrides the project’s Base SDK setting

In Xcode, you always open projects (or workspaces, but not targets), and all the targets it contains can be built/run, but there’s no way/definition of building a project, so every project needs at least one target in order to be more than just a collection of files and settings.

Select one of the project’s targets to run

In a lot of cases, projects are all you need. If you have a dependency that you build from source, you can embed it as a subproject. Subprojects can be opened separately or within their super project.

demoLib is a subproject

If you add one of the subproject’s targets to the super project’s dependencies, the subproject will be automatically built unless it has remained unchanged. The advantage here is that you can edit files from both your project and your dependencies in the same Xcode window, and when you build/run, you can select from the project’s and its subprojects’ targets:

If, however, your library (the subproject) is used by a variety of other projects (or their targets, to be precise), it makes sense to put it on the same hierarchy level – that’s what workspaces are for. Workspaces contain and manage projects, and all the projects it includes directly (i.e., not their subprojects) are on the same level and their targets can depend on each other (projects’ targets can depend on subprojects’ targets, but not vice versa).

Workspace structure

In this example, both apps (AnotherApplication / ProjectStructureExample) can reference the demoLib project’s targets. This would also be possible by including the demoLib project in both other projects as a subproject (which is a reference only, so no duplication necessary), but if you have lots of cross-dependencies, workspaces make more sense. If you open a workspace, you can choose from all projects’ targets when building/running.

You can still open your project files separately, but it is likely their targets won’t build because Xcode cannot resolve the dependencies unless you open the workspace file. Workspaces give you the same benefit as subprojects: Once a dependency changes, Xcode will rebuild it to make sure it’s up-to-date (although I have had some issues with that, it doesn’t seem to work reliably).

Your questions in a nutshell:

1) Projects contain files (code/resouces), settings, and targets that build products from those files and settings. Workspaces contain projects which can reference each other.

2) Both are responsible for structuring your overall project, but on different levels.

3) I think projects are sufficient in most cases. Don’t use workspaces unless there’s a specific reason. Plus, you can always embed your project in a workspace later.

4) I think that’s what the above text is for…

There’s one remark for 3): CocoaPods, which automatically handles 3rd party libraries for you, uses workspaces. Therefore, you have to use them, too, when you use CocoaPods (which a lot of people do).

Name of the table and rows counter for all tables under OWNER schema:

SELECT table_name, num_rows counter from DBA_TABLES WHERE owner = 'OWNER'

If the file is in the same directory as the one where the .md is, then just putting [Click here](MY-FILE.md) should work.

Otherwise, can create a path from the root directory of the project. So if the entire project/git-repo root directory is called 'my-app', and one wants to point to my-app/client/read-me.md, then try [My hyperlink](/client/read-me.md).

At least works from Chrome.

When using the new ruby, the image folder will go to asset folder on folder app

after placing your images in image folder, use

<%=image_tag("example_image.png", alt: "Example Image")%>

All you need is..

v2= v1.GetValueOrDefault();

vim +21490go script.py

From the command line will open the file and take you to position 21490 in the buffer.

Triggering it from the command line like this allows you to automate a script to parse the exception message and open the file to the problem position.

Excerpt from man vim:

+{command}

-c {command}

{command} will be executed after the first file has been read. {command} is interpreted as an Ex command. If the {command} contains spaces it must be enclosed in double quotes (this depends on the shell that is used).

I'm not saying that Array -> |value,index| and Hash -> |key,value| is not insane (see Horace Loeb's comment), but I am saying that there is a sane way to expect this arrangement.

When I am dealing with arrays, I am focused on the elements in the array (not the index because the index is transitory). The method is each with index, i.e. each+index, or |each,index|, or |value,index|. This is also consistent with the index being viewed as an optional argument, e.g. |value| is equivalent to |value,index=nil| which is consistent with |value,index|.

When I am dealing with hashes, I am often more focused on the keys than the values, and I am usually dealing with keys and values in that order, either key => value or hash[key] = value.

If you want duck-typing, then either explicitly use a defined method as Brent Longborough showed, or an implicit method as maxhawkins showed.

Ruby is all about accommodating the language to suit the programmer, not about the programmer accommodating to suit the language. This is why there are so many ways. There are so many ways to think about something. In Ruby, you choose the closest and the rest of the code usually falls out extremely neatly and concisely.

As for the original question, "What is the “right” way to iterate through an array in Ruby?", well, I think the core way (i.e. without powerful syntactic sugar or object oriented power) is to do:

for index in 0 ... array.size
  puts "array[#{index}] = #{array[index].inspect}"
end

But Ruby is all about powerful syntactic sugar and object oriented power, but anyway here is the equivalent for hashes, and the keys can be ordered or not:

for key in hash.keys.sort
  puts "hash[#{key.inspect}] = #{hash[key].inspect}"
end

So, my answer is, "The “right” way to iterate through an array in Ruby depends on you (i.e. the programmer or the programming team) and the project.". The better Ruby programmer makes the better choice (of which syntactic power and/or which object oriented approach). The better Ruby programmer continues to look for more ways.

Now, I want to ask another question, "What is the “right” way to iterate through a Range in Ruby backwards?"! (This question is how I came to this page.)

It is nice to do (for the forwards):

(1..10).each{|i| puts "i=#{i}" }

but I don't like to do (for the backwards):

(1..10).to_a.reverse.each{|i| puts "i=#{i}" }

Well, I don't actually mind doing that too much, but when I am teaching going backwards, I want to show my students a nice symmetry (i.e. with minimal difference, e.g. only adding a reverse, or a step -1, but without modifying anything else). You can do (for symmetry):

(a=*1..10).each{|i| puts "i=#{i}" }

and

(a=*1..10).reverse.each{|i| puts "i=#{i}" }

which I don't like much, but you can't do

(*1..10).each{|i| puts "i=#{i}" }
(*1..10).reverse.each{|i| puts "i=#{i}" }
#
(1..10).step(1){|i| puts "i=#{i}" }
(1..10).step(-1){|i| puts "i=#{i}" }
#
(1..10).each{|i| puts "i=#{i}" }
(10..1).each{|i| puts "i=#{i}" }   # I don't want this though.  It's dangerous

You could ultimately do

class Range

  def each_reverse(&block)
    self.to_a.reverse.each(&block)
  end

end

but I want to teach pure Ruby rather than object oriented approaches (just yet). I would like to iterate backwards:

• without creating an array (consider 0..1000000000)
• working for any Range (e.g. Strings, not just Integers)
• without using any extra object oriented power (i.e. no class modification)

I believe this is impossible without defining a pred method, which means modifying the Range class to use it. If you can do this please let me know, otherwise confirmation of impossibility would be appreciated though it would be disappointing. Perhaps Ruby 1.9 addresses this.

(Thanks for your time in reading this.)

Summary:

• PagingAndSortingRepository extends CrudRepository

• JpaRepository extends PagingAndSortingRepository

The CrudRepository interface provides methods for CRUD operations, so it allows you to create, read, update and delete records without having to define your own methods.

The PagingAndSortingRepository provides additional methods to retrieve entities using pagination and sorting.

Finally the JpaRepository add some more functionality that is specific to JPA.

Now you can use shelljs ( from node v4 ) as follows :

var shell = require('shelljs');

shell.echo('hello world');
shell.exec('node --version')

Yet another answer:

def addGetParameters(url, newParams):
    (scheme, netloc, path, params, query, fragment) = urlparse.urlparse(url)
    queryList = urlparse.parse_qsl(query, keep_blank_values=True)
    for key in newParams:
        queryList.append((key, newParams[key]))
    return urlparse.urlunparse((scheme, netloc, path, params, urllib.urlencode(queryList), fragment))

Put the @optional in front of methods or properties.

After the advice here, I have devised the following function in VB which creates passable, although not always perfect (if a company name and a suite line are given, it combines the suite and city) usable data. Please feel free to comment/refactor/yell at me for breaking one of my own rules, etc.:

Public Function parseAddress(ByVal input As String) As Collection
    input = input.Replace(",", "")
    input = input.Replace("  ", " ")
    Dim splitString() As String = Split(input)
    Dim streetMarker() As String = New String() {"street", "st", "st.", "avenue", "ave", "ave.", "blvd", "blvd.", "highway", "hwy", "hwy.", "box", "road", "rd", "rd.", "lane", "ln", "ln.", "circle", "circ", "circ.", "court", "ct", "ct."}
    Dim address1 As String
    Dim address2 As String = ""
    Dim city As String
    Dim state As String
    Dim zip As String
    Dim streetMarkerIndex As Integer

    zip = splitString(splitString.Length - 1).ToString()
    state = splitString(splitString.Length - 2).ToString()
    streetMarkerIndex = getLastIndexOf(splitString, streetMarker) + 1
    Dim sb As New StringBuilder

    For counter As Integer = streetMarkerIndex To splitString.Length - 3
        sb.Append(splitString(counter) + " ")
    Next counter
    city = RTrim(sb.ToString())
    Dim addressIndex As Integer = 0

    For counter As Integer = 0 To streetMarkerIndex
        If IsNumeric(splitString(counter)) _
            Or splitString(counter).ToString.ToLower = "po" _
            Or splitString(counter).ToString().ToLower().Replace(".", "") = "po" Then
                addressIndex = counter
            Exit For
        End If
    Next counter

    sb = New StringBuilder
    For counter As Integer = addressIndex To streetMarkerIndex - 1
        sb.Append(splitString(counter) + " ")
    Next counter

    address1 = RTrim(sb.ToString())

    sb = New StringBuilder

    If addressIndex = 0 Then
        If splitString(splitString.Length - 2).ToString() <> splitString(streetMarkerIndex + 1) Then
            For counter As Integer = streetMarkerIndex To splitString.Length - 2
                sb.Append(splitString(counter) + " ")
            Next counter
        End If
    Else
        For counter As Integer = 0 To addressIndex - 1
            sb.Append(splitString(counter) + " ")
        Next counter
    End If
    address2 = RTrim(sb.ToString())

    Dim output As New Collection
    output.Add(address1, "Address1")
    output.Add(address2, "Address2")
    output.Add(city, "City")
    output.Add(state, "State")
    output.Add(zip, "Zip")
    Return output
End Function

Private Function getLastIndexOf(ByVal sArray As String(), ByVal checkArray As String()) As Integer
    Dim sourceIndex As Integer = 0
    Dim outputIndex As Integer = 0
    For Each item As String In checkArray
        For Each source As String In sArray
            If source.ToLower = item.ToLower Then
                outputIndex = sourceIndex
                If item.ToLower = "box" Then
                    outputIndex = outputIndex + 1
                End If
            End If
            sourceIndex = sourceIndex + 1
        Next
        sourceIndex = 0
    Next
    Return outputIndex
End Function

Passing the parseAddress function "A. P. Croll & Son 2299 Lewes-Georgetown Hwy, Georgetown, DE 19947" returns:

2299 Lewes-Georgetown Hwy
A. P. Croll & Son  
Georgetown
DE
19947

I think you are trying to over complicate things. A simple solution is to just style your checkbox by default with the unchecked styles and then add the checked state styles.

input[type="checkbox"] {
  // Unchecked Styles
}
input[type="checkbox"]:checked {
  // Checked Styles
}

I apologize for bringing up an old thread but felt like it could have used a better answer.

EDIT (3/3/2016):

W3C Specs state that :not(:checked) as their example for selecting the unchecked state. However, this is explicitly the unchecked state and will only apply those styles to the unchecked state. This is useful for adding styling that is only needed on the unchecked state and would need removed from the checked state if used on the input[type="checkbox"] selector. See example below for clarification.

input[type="checkbox"] {
  /* Base Styles aka unchecked */
  font-weight: 300; // Will be overwritten by :checked
  font-size: 16px; // Base styling
}
input[type="checkbox"]:not(:checked) {
  /* Explicit Unchecked Styles */
  border: 1px solid #FF0000; // Only apply border to unchecked state
}
input[type="checkbox"]:checked {
  /* Checked Styles */
  font-weight: 900; // Use a bold font when checked
}

Without using :not(:checked) in the example above the :checked selector would have needed to use a border: none; to achieve the same affect.

Use the input[type="checkbox"] for base styling to reduce duplication.

Use the input[type="checkbox"]:not(:checked) for explicit unchecked styles that you do not want to apply to the checked state.

    public void BubbleSortNum()
    {
        int[] a = {10,5,30,25,40,20};
        int length = a.Length;
        int temp = 0; 
        for (int i = 0; i <length; i++)
        {               
            for(int j=i;j<length; j++)
            {
                if (a[i]>a[j])
                {
                    temp = a[j];
                    a[j] = a[i];
                    a[i] = temp;
                }     
            }
           Console.WriteLine(a[i]);
        }       
     }

I have encountered the same problem you have. I found that it may have some relationship with the way you terminate your run result. When you run your code, whether it has a printout, the debugger will call the console which print a "Press any key to continue...". If you terminate the console by pressing key, it's ok; if you do it by click the close button, the problem comes as you described. When you terminate it in the latter way, you have to wait several minutes before you can rebuild your code.

Using -s option will print output of all functions, which may be too much.

If you need particular output, the doc page you mentioned offers few suggestions:

1. Insert assert False, "dumb assert to make PyTest print my stuff" at the end of your function, and you will see your output due to failed test.

2. You have special object passed to you by PyTest, and you can write the output into a file to inspect it later, like

   def test_good1(capsys):
       for i in range(5):
           print i
       out, err = capsys.readouterr()
       open("err.txt", "w").write(err)
       open("out.txt", "w").write(out)
   

   You can open the out and err files in a separate tab and let editor automatically refresh it for you, or do a simple py.test; cat out.txt shell command to run your test.

That is rather hackish way to do stuff, but may be it is the stuff you need: after all, TDD means you mess with stuff and leave it clean and silent when it's ready :-).

That's no problem.

@Html.Partial("../Controller/View", model)

or

@Html.Partial("~/Views/Controller/View.cshtml", model)

Should do the trick.

If you want to pass through the (other) controller, you can use:

@Html.Action("action", "controller", parameters)

or any of the other overloads

This problem arises when you have a custom class that extends a different class (in this case a view) and does not import all the constructors required by the class.

For eg : public class CustomTextView extends TextView{}

This class would have 4 constructors and if you miss out on any one it would crash. For the matter of fact I missed out the last one which was used by Lollipop added that constructor and worked fine.

The short answer is that you can't.

There are various tools around that will make it harder for someone to read your code - some of which have been pointed out by other answers.

However, all these do is make it harder to read - they increase the amount of effort required, that is all. Often this is enough to deter casual readers, but someone who is determined to dig into your code will always be able to do so.

CTRL - ML toggles line numbers in the CodeMirror area. See the QuickHelp for other keyboard shortcuts.

In more details CTRL - M (or ESC) bring you to command mode, then pressing the L keys should toggle the visibility of current cell line numbers. In more recent notebook versions Shift-L should toggle for all cells.

If you can't remember the shortcut, bring up the command palette Ctrl-Shift+P (Cmd+Shift+P on Mac), and search for "line numbers"), it should allow to toggle and show you the shortcut.

DCEVM supports enhanced class redefinitions and is available for current JDK7 and JDK8.

Try this piece of code, it worked for me:

$('#year').datepicker({
    format: "yyyy",
    viewMode: "years",
    minViewMode: "years"
});

I hope it will do magic also for you.

OUTDATED: Many modern browsers now have first-class support for crypto operations. See Vitaly Zdanevich's answer below.

The Stanford JS Crypto Library contains an implementation of SHA-256. While crypto in JS isn't really as well-vetted an endeavor as other implementation platforms, this one is at least partially developed by, and to a certain extent sponsored by, Dan Boneh, who is a well-established and trusted name in cryptography, and means that the project has some oversight by someone who actually knows what he's doing. The project is also supported by the NSF.

It's worth pointing out, however...
... that if you hash the password client-side before submitting it, then the hash is the password, and the original password becomes irrelevant. An attacker needs only to intercept the hash in order to impersonate the user, and if that hash is stored unmodified on the server, then the server is storing the true password (the hash) in plain-text.

So your security is now worse because you decided add your own improvements to what was previously a trusted scheme.

Paul Welter's ASP.NET blog has a dictionary that is serializeable. But it does not use attributes. I will explain why below the code.

using System;
using System.Collections.Generic;
using System.Text;
using System.Xml.Serialization;

[XmlRoot("dictionary")]
public class SerializableDictionary<TKey, TValue>
    : Dictionary<TKey, TValue>, IXmlSerializable
{
    #region IXmlSerializable Members
    public System.Xml.Schema.XmlSchema GetSchema()
    {
        return null;
    }

    public void ReadXml(System.Xml.XmlReader reader)
    {
        XmlSerializer keySerializer = new XmlSerializer(typeof(TKey));
        XmlSerializer valueSerializer = new XmlSerializer(typeof(TValue));

        bool wasEmpty = reader.IsEmptyElement;
        reader.Read();

        if (wasEmpty)
            return;

        while (reader.NodeType != System.Xml.XmlNodeType.EndElement)
        {
            reader.ReadStartElement("item");

            reader.ReadStartElement("key");
            TKey key = (TKey)keySerializer.Deserialize(reader);
            reader.ReadEndElement();

            reader.ReadStartElement("value");
            TValue value = (TValue)valueSerializer.Deserialize(reader);
            reader.ReadEndElement();

            this.Add(key, value);

            reader.ReadEndElement();
            reader.MoveToContent();
        }
        reader.ReadEndElement();
    }

    public void WriteXml(System.Xml.XmlWriter writer)
    {
        XmlSerializer keySerializer = new XmlSerializer(typeof(TKey));
        XmlSerializer valueSerializer = new XmlSerializer(typeof(TValue));

        foreach (TKey key in this.Keys)
        {
            writer.WriteStartElement("item");

            writer.WriteStartElement("key");
            keySerializer.Serialize(writer, key);
            writer.WriteEndElement();

            writer.WriteStartElement("value");
            TValue value = this[key];
            valueSerializer.Serialize(writer, value);
            writer.WriteEndElement();

            writer.WriteEndElement();
        }
    }
    #endregion
}

First, there is one gotcha with this code. Say you read a dictionary from another source that has this:

<dictionary>
  <item>
    <key>
      <string>key1</string>
    </key>
    <value>
      <string>value1</string>
    </value>
  </item>
  <item>
    <key>
      <string>key1</string>
    </key>
    <value>
      <string>value2</string>
    </value>
  </item>
</dictionary>

This will throw a exception on de-seariazation because you can only have one key for a dictionary.

The reason you MUST use a XElement in a seriazed dictionary is dictionary is not defined as Dictionary<String,String>, a dictionary is Dictionary<TKey,TValue>.

To see the problem, ask your self: Lets say we have a TValue that serializes in to something that uses Elements it describes itself as XML (lets say a dictionary of dictionaries Dictionary<int,Dictionary<int,string>> (not that uncommon of a pattern, it's a lookup table)), how would your Attribute only version represent a dictionary entirely inside a attribute?

I know this is a little off the OPs original request but I came across this while looking for a way to use Invoke-WebRequest against a site requiring basic authentication.

The difference is, I did not want to record the password in the script. Instead, I wanted to prompt the script runner for credentials for the site.

Here's how I handled it

$creds = Get-Credential

$basicCreds = [pscredential]::new($Creds.UserName,$Creds.Password)

Invoke-WebRequest -Uri $URL -Credential $basicCreds

The result is the script runner is prompted with a login dialog for the U/P then, Invoke-WebRequest is able to access the site with those credentials. This works because $Creds.Password is already an encrypted string.

I hope this helps someone looking for a similar solution to the above question but without saving the username or PW in the script

I have another suggestion. When you want myDiv to have a height of 100%, use these extra 3 attributes on your div:

myDiv {
    min-height: 100%;
    overflow-y: hidden;
    position: relative;
}

That should do the job!

The Maven Dependency Plugin will help, especially the dependency:analyze goal:

dependency:analyze analyzes the dependencies of this project and determines which are: used and declared; used and undeclared; unused and declared.

Another thing that might help to do some cleanup is the Dependency Convergence report from the Maven Project Info Reports Plugin.

NVL(value, default) is the function you are looking for.

select type, craft, sum(NVL(regular, 0) + NVL(overtime, 0) ) as total_hours
from hours_t
group by type, craft
order by type, craft

Oracle have 5 NULL-related functions:

1. NVL
2. NVL2
3. COALESCE
4. NULLIF
5. LNNVL

NVL:

NVL(expr1, expr2)

NVL lets you replace null (returned as a blank) with a string in the results of a query. If expr1 is null, then NVL returns expr2. If expr1 is not null, then NVL returns expr1.

NVL2 :

NVL2(expr1, expr2, expr3)

NVL2 lets you determine the value returned by a query based on whether a specified expression is null or not null. If expr1 is not null, then NVL2 returns expr2. If expr1 is null, then NVL2 returns expr3.

COALESCE

COALESCE(expr1, expr2, ...)

COALESCE returns the first non-null expr in the expression list. At least one expr must not be the literal NULL. If all occurrences of expr evaluate to null, then the function returns null.

NULLIF

NULLIF(expr1, expr2)

NULLIF compares expr1 and expr2. If they are equal, then the function returns null. If they are not equal, then the function returns expr1. You cannot specify the literal NULL for expr1.

LNNVL

LNNVL(condition)

LNNVL provides a concise way to evaluate a condition when one or both operands of the condition may be null.

Assuming WinForms, the ForeColor property allows to change all the text in the TextBox (not just what you're about to add):

TextBox.ForeColor = Color.Red;

To only change the color of certain words, look at RichTextBox.

You are looking for a simple code, like this:

    List<string> tagList = new List<string>(new[]
    {
         "A"
        ,"B"
        ,"C"
        ,"D"
        ,"E"
    });

Ok, looks like I missed an obvious step, but posting this in case anyone else does the same.

When upgrading to 1.7, my models became unmanaged (managed = False) - I had them as True before but seems it got reverted.

Removing that line (To default to True) and then running makemigrations immediately made a migration module and now it's working. makemigrations will not work on unmanaged tables (Which is obvious in hindsight)

There is an command line application called "ShowVer" at CodeProject:

Although, I'm a big fan of Kanban Tool service (it has everything you need except free of charge) and therefore it's difficult for me to stay objective, I think that should go for Trello or Kanban Flow. Both are free and both provide basic features that are essential for agile process managers and their teams.

For pyftpdlib users. I found this on the pyftpdlib website. This creates anonymous ftp with write access to your filesystem so please use with due care. More features are available under the hood for better security so just go look:

sudo pip3 install pyftpdlib

python3 -m pyftpdlib -w  

## updated for python3 Feb14:2020

Might be helpful for those that tried using the deprecated method above.

sudo python -m pyftpdlib.ftpserver

varchar: Variable-length, non-Unicode character data. The database collation determines which code page the data is stored using.

nvarchar: Variable-length Unicode character data. Dependent on the database collation for comparisons.

Armed with this knowledge, use whichever one matches your input data (ASCII v. Unicode).

You just need to manually set the desired permissions with chmod():

private function writeFileContent($file, $content){
    $fp = fopen($file, 'w');
    fwrite($fp, $content);
    fclose($fp);

    // Set perms with chmod()
    chmod($file, 0777);
    return true;
}

After installing openjdk with brew and runnning brew info openjdk I got this

And from that I got this command here, and after running it I got Java working

sudo ln -sfn /usr/local/opt/openjdk/libexec/openjdk.jdk /Library/Java/JavaVirtualMachines/openjdk.jdk

Depth first traversal of a binary tree is of order O(n).

Algo -- <b>
    PreOrderTrav():-----------------T(n)<b>
    if root is null---------------O(1)<b>
      return null-----------------O(1)<b>
    else:-------------------------O(1)<b>
      print(root)-----------------O(1)<b>
      PreOrderTrav(root.left)-----T(n/2)<b>
      PreOrderTrav(root.right)----T(n/2)<b>

If the time complexity of the algo is T(n) then it can be written as T(n) = 2*T(n/2) + O(1). If we apply back substitution we will get T(n) = O(n).

Run a test.

   string coerce:          7.42296099663

   string fail coerce:     7.14159703255
   string fail cast:       7.87444186211

This was a test that ran each scenario 10,000,000 times. :-)

Co-ercion is 0 + "123"

Casting is (integer)"123"

I think Co-ercion is a tiny bit faster. Oh, and trying 0 + array('123') is a fatal error in PHP. You might want your code to check the type of the supplied value.

My test code is below.

function test_string_coerce($s) {
    return 0 + $s;
}

function test_string_cast($s) {
    return (integer)$s;
}

$iter = 10000000;

print "-- running each text $iter times.\n";

// string co-erce
$string_coerce = new Timer;
$string_coerce->Start();

print "String Coerce test\n";
for( $i = 0; $i < $iter ; $i++ ) {
    test_string_coerce('123');
}

$string_coerce->Stop();

// string cast
$string_cast = new Timer;
$string_cast->Start();

print "String Cast test\n";
for( $i = 0; $i < $iter ; $i++ ) {
    test_string_cast('123');
}

$string_cast->Stop();

// string co-erce fail.
$string_coerce_fail = new Timer;
$string_coerce_fail->Start();

print "String Coerce fail test\n";
for( $i = 0; $i < $iter ; $i++ ) {
    test_string_coerce('hello');
}

$string_coerce_fail->Stop();

// string cast fail
$string_cast_fail = new Timer;
$string_cast_fail->Start();

print "String Cast fail test\n";
for( $i = 0; $i < $iter ; $i++ ) {
    test_string_cast('hello');
}

$string_cast_fail->Stop();

// -----------------
print "\n";
print "string coerce:          ".$string_coerce->Elapsed()."\n";
print "string cast:            ".$string_cast->Elapsed()."\n";
print "string fail coerce:     ".$string_coerce_fail->Elapsed()."\n";
print "string fail cast:       ".$string_cast_fail->Elapsed()."\n";


class Timer {
    var $ticking = null;
    var $started_at = false;
    var $elapsed = 0;

    function Timer() {
        $this->ticking = null;
    }

    function Start() {
        $this->ticking = true;
        $this->started_at = microtime(TRUE);
    }

    function Stop() {
        if( $this->ticking )
            $this->elapsed = microtime(TRUE) - $this->started_at;
        $this->ticking = false;
    }

    function Elapsed() {
        switch( $this->ticking ) {
            case true: return "Still Running";
            case false: return $this->elapsed;
            case null: return "Not Started";
        }
    }
}

Here is a small function I wrote to try all the colorschemes in $VIMRUNTIME/colors directory.

Add the below function to your vimrc, then open your source file and call the function from command.

function! DisplayColorSchemes()
   let currDir = getcwd()
   exec "cd $VIMRUNTIME/colors"
   for myCol in split(glob("*"), '\n')
      if myCol =~ '\.vim'
         let mycol = substitute(myCol, '\.vim', '', '')
         exec "colorscheme " . mycol
         exec "redraw!"
         echo "colorscheme = ". myCol
         sleep 2
      endif
   endfor
   exec "cd " . currDir
endfunction

If you need to use " and " instead of ", " between the last two items you can do this:

function arrayToList(array){
  return array
    .join(", ")
    .replace(/, ((?:.(?!, ))+)$/, ' and $1');
}

Here are couple of utility functions I use to do just this.

/**
 * sets all the time related fields to ZERO!
 *
 * @param date
 *
 * @return Date with hours, minutes, seconds and ms set to ZERO!
 */
public static Date zeroTime( final Date date )
{
    return DateTimeUtil.setTime( date, 0, 0, 0, 0 );
}

/**
 * Set the time of the given Date
 *
 * @param date
 * @param hourOfDay
 * @param minute
 * @param second
 * @param ms
 *
 * @return new instance of java.util.Date with the time set
 */
public static Date setTime( final Date date, final int hourOfDay, final int minute, final int second, final int ms )
{
    final GregorianCalendar gc = new GregorianCalendar();
    gc.setTime( date );
    gc.set( Calendar.HOUR_OF_DAY, hourOfDay );
    gc.set( Calendar.MINUTE, minute );
    gc.set( Calendar.SECOND, second );
    gc.set( Calendar.MILLISECOND, ms );
    return gc.getTime();
}

Try this:

select * from artists where name like "A%" or name like "B%" or name like "C%"

However, if you use a better serializer like dill or cloudpickle, then most dictionaries can be pickled:

>>> import dill
>>> pik = dill.dumps(d)

Or if you want to save your dict to a file...

>>> with open('save.pik', 'w') as f:
...   dill.dump(globals(), f)
... 

The latter example is identical to any of the other good answers posted here (which aside from neglecting the picklability of the contents of the dict are good).

I added the DLLs manually. Right clicked on References in the project, select Add Reference and then in the dialog pressed the Browse button. The NuGet DLLs where in the packages directory of the solution. To get the names of them you can right click on references in another project that's working properly and select properties and look in the path property.

I worked it around through this "hiding" div ...

The web host is not really playing foul. It's not strictly according to the rules - but compared with some some of the amazing inventions intended to prevent spam, its not a particularly bad one.

If you really do want to send mail from '@gmail.com' why not just use the gmail SMTP service? If you can't reconfigure the server where PHP is running, then there are lots of email wrapper tools out there which allow you to specify a custom SMTP relay phpmailer springs to mind.

double and Double are the same (double is an alias for Double) and can be used interchangeably.

The problem with comparing a double with another value is that doubles are approximate values, not exact values. So when you set x to 0.1 it may in reality be stored as 0.100000001 or something like that.

Instead of checking for equality, you should check that the difference is less than a defined minimum difference (tolerance). Something like:

if (Math.Abs(x - 0.1) < 0.0000001)
{
    ...
}

The compiler complains that you are trying something of a list of ClientThread objects to a String. Either change the type of hey to ClientThread or clients to List<String>.

In addition: Valid indices for lists are from 0 to size()-1.

So you probably want to write

   String hey = clients.get(clients.size()-1);

partition by doesn't actually roll up the data. It allows you to reset something on a per group basis. For example, you can get an ordinal column within a group by partitioning on the grouping field and using rownum() over the rows within that group. This gives you something that behaves a bit like an identity column that resets at the beginning of each group.

If you need to increase MySQL Connections without MySQL restart do like below

mysql> show variables like 'max_connections';
+-----------------+-------+
| Variable_name   | Value |
+-----------------+-------+
| max_connections | 100   |
+-----------------+-------+
1 row in set (0.00 sec)

mysql> SET GLOBAL max_connections = 150;
Query OK, 0 rows affected (0.00 sec)

mysql> show variables like 'max_connections';
+-----------------+-------+
| Variable_name   | Value |
+-----------------+-------+
| max_connections | 150   |
+-----------------+-------+
1 row in set (0.00 sec)

These settings will change at MySQL Restart.

For permanent changes add below line in my.cnf and restart MySQL

max_connections = 150

Should switch statements always contain a default clause ? No switch cases can exist with out default case, in switch case default case will trigger switch value switch(x) in this case x when not match with any other case values.

Run a select to make sure it is what you want

SELECT t1.value AS NEWVALUEFROMTABLE1,t2.value AS OLDVALUETABLE2,*
FROM Table2 t2
INNER JOIN Table1 t1 on t1.ID = t2.ID

Update

UPDATE Table2
SET Value = t1.Value
FROM Table2 t2
INNER JOIN Table1 t1 on t1.ID = t2.ID

Also, consider using BEGIN TRAN so you can roll it back if needed, but make sure you COMMIT it when you are satisfied.

In my mind I have to consider that the foo folder is a stand-alone library. I might want to consider moving it to the Lib\site-packages folder within a python installation. I might want to consider adding a foo.pth file there.

I know it's a library since the ./programs/my_python_program.py contains the following line:

from foo.tasks import my_function

So it doesn't matter that ./programs is a sibling folder to ./foo. It's the fact that my_python_program.py is run as a script like this:

python ./programs/my_python_program.py

Adding _CRT_SECURE_NO_WARNINGS to Project -> Properties -> C/C++ -> Preprocessor -> Preprocessor Definitions didn't work for me, don't know why.

The following hint works: In stdafx.h file, please add

#define _CRT_SECURE_NO_DEPRECATE

before include other header files.

You can compare for exactly the same type using:

class A {
}
var a = new A();
var typeOfa = a.GetType();
if (typeOfa == typeof(A)) {
}

typeof returns the Type object from a given class.

But if you have a type B, that inherits from A, then this comparison is false. And you are looking for IsAssignableFrom.

class B : A {
}
var b = new B();
var typeOfb = b.GetType();

if (typeOfb == typeof(A)) { // false
}

if (typeof(A).IsAssignableFrom(typeOfb)) { // true
}

You now can do this with Flexbox justify-content: flex-end now:

div {_x000D_

Since you accepted an answer in which a list was not used, I'll assume the answer to my comment question is "No, it doesn't have to be a list". I also had the impression that maybe you were rending the HTML server side, since "checked" is present in your sample HTML (this would not be needed if ng-model were used to model your checkboxes).

Anyway, here's what I had in mind when I asked the question, also assuming you were generating the HTML server-side:

<div ng-controller="MyCtrl" 
 ng-init="checkboxes = {apple: true, orange: false, pear: true, naartjie: false}">
    <input type="checkbox" ng-model="checkboxes.apple">apple
    <input type="checkbox" ng-model="checkboxes.orange">orange
    <input type="checkbox" ng-model="checkboxes.pear">pear
    <input type="checkbox" ng-model="checkboxes.naartjie">naartjie
    <br>{{checkboxes}}
</div>

ng-init allows server-side generated HTML to initially set certain checkboxes.

Fiddle.

One solution for this can be found with find.

$ mkdir foo bar
$ touch foo/a.txt foo/Music.txt
$ find foo -type f ! -name '*Music*' -exec cp {} bar \;
$ ls bar
a.txt

Find has quite a few options, you can get pretty specific on what you include and exclude.

Edit: Adam in the comments noted that this is recursive. find options mindepth and maxdepth can be useful in controlling this.

Don't forget that integers can be negative:

^\s*-?[0-9]{1,10}\s*$

Here's the meaning of each part:

• ^: Match must start at beginning of string
• \s: Any whitespace character
  • *: Occurring zero or more times
• -: The hyphen-minus character, used to denote a negative integer
  • ?: May or may not occur
• [0-9]: Any character whose ASCII code (or Unicode code point) is between '0' and '9'
  • {1,10}: Occurring at least one, but not more than ten times
• \s: Any whitespace character
  • *: Occurring zero or more times
• $: Match must end at end of string

This ignores leading and trailing whitespace and would be more complex if you consider commas acceptable or if you need to count the minus sign as one of the ten allowed characters.

If you want to just shift everything down you can use:

Rows(1).Insert shift:=xlShiftDown

Similarly to shift everything over:

Columns(1).Insert shift:=xlShiftRight

This exact question is answered on mySql workbench-faq:

Hover over an acronym to view a description, and see the Section 8.1.11.2, “The Columns Tab” and MySQL CREATE TABLE documentation for additional details.

That means hover over an acronym in the mySql Workbench table editor.

Section 8.1.11.2, “The Columns Tab”

I'm not sure that the method that you give is really inefficient, but an alternate way, as long as it doesn't have to be flexible in the length or padding character, would be (assuming that you want to pad it with "0" to 10 characters:

DECLARE
   @pad_characters VARCHAR(10)

SET @pad_characters = '0000000000'

SELECT RIGHT(@pad_characters + @str, 10)

I have had the same problem, but none of the answers quite gave a step by step of what I needed to do. This error happens because your socket file has not been created yet. All you have to do is:

1. Start you mysql server, so your /tmp/mysql.sock is created, to do that you run: mysql server start
2. Once that is done, go to your app directory end edit the config/database.yml file and add/edit the socket: /tmp/mysql.sock entry
3. Run rake:dbmigrate once again and everything should workout fine

If you're just looking for a single character, this would work:

string = "dooobiedoobiedoobie"
match = 'o'
reduce(lambda count, char: count + 1 if char == match else count, string, 0)
# produces 7

Also,

string = "test test test test"
match = "test"
len(string.split(match)) - 1
# produces 4

My hunch is that neither of these (especially #2) is terribly performant.

One possible way is to use .map() method:

var all = $(".mbox").map(function() {
    return this.innerHTML;
}).get();

console.log(all.join());

DEMO: http://jsfiddle.net/Y4bHh/

N.B. Please don't use document.write. For testing purposes console.log is the best way to go.

I tried the methods mentioned in some other answers, but they look like workarounds to me. Using Firefox Add-on RESTclient to send HTTP POST requests with parameters is not straightforward in my opinion, at least for the version I'm currently using, 2.0.1.

Instead, try using other free open source tools, such as Apache JMeter. It is simple and straightforward (see the screenshot as below)

Taken from http://forum.jquery.com/topic/multiple-versions-of-jquery-on-the-same-page:

• Original page loads his "jquery.versionX.js" -- $ and jQuery belong to versionX.
• You call your "jquery.versionY.js" -- now $ and jQuery belong to versionY, plus _$ and _jQuery belong to versionX.
• my_jQuery = jQuery.noConflict(true); -- now $ and jQuery belong to versionX, _$ and _jQuery are probably null, and my_jQuery is versionY.

You may be interested in Python interactive tutorial for begginers and advance users , it has many available practices together with interactive interface + advance development tricks for advance users.

The problem is with the method:

private void Flow()
{
    X = x;
    Y = y;
}

Your class is named Flow so this method can't also be named Flow. You will have to change the name of the Flow method to something else to make this code compile.

Or did you mean to create a private constructor to initialize your class? If that's the case, you will have to remove the void keyword to let the compiler know that your declaring a constructor.

The main difference with shell config files is that some are only read by "login" shells (eg. when you login from another host, or login at the text console of a local unix machine). these are the ones called, say, .login or .profile or .zlogin (depending on which shell you're using).

Then you have config files that are read by "interactive" shells (as in, ones connected to a terminal (or pseudo-terminal in the case of, say, a terminal emulator running under a windowing system). these are the ones with names like .bashrc, .tcshrc, .zshrc, etc.

bash complicates this in that .bashrc is only read by a shell that's both interactive and non-login, so you'll find most people end up telling their .bash_profile to also read .bashrc with something like

[[ -r ~/.bashrc ]] && . ~/.bashrc

Other shells behave differently - eg with zsh, .zshrc is always read for an interactive shell, whether it's a login one or not.

The manual page for bash explains the circumstances under which each file is read. Yes, behaviour is generally consistent between machines.

.profile is simply the login script filename originally used by /bin/sh. bash, being generally backwards-compatible with /bin/sh, will read .profile if one exists.

The 2017 answer is: Use the date and time classes introduced in Java 8 (and also backported to Java 6 and 7 in the ThreeTen Backport).

If you want to interpret the date-time string in the computer’s time zone:

    long millisSinceEpoch = LocalDateTime.parse(myDate, DateTimeFormatter.ofPattern("uuuu/MM/dd HH:mm:ss"))
            .atZone(ZoneId.systemDefault())
            .toInstant()
            .toEpochMilli();

If another time zone, fill that zone in instead of ZoneId.systemDefault(). If UTC, use

    long millisSinceEpoch = LocalDateTime.parse(myDate, DateTimeFormatter.ofPattern("uuuu/MM/dd HH:mm:ss"))
            .atOffset(ZoneOffset.UTC)
            .toInstant()
            .toEpochMilli();

UPDATE

This was an old answer. Nowadays you should just use click. For more advanced event firing, use dispatchEvent.

const body = document.body;_x000D_
_x000D_
body.addEventListener('click', e => {_x000D_
  console.log('clicked body');_x000D_
});_x000D_
_x000D_
console.log('Using click()');_x000D_
body.click();_x000D_
_x000D_
console.log('Using dispatchEvent');_x000D_
body.dispatchEvent(new Event('click'));

Original Answer

Here is what I use: http://jsfiddle.net/mendesjuan/rHMCy/4/

Updated to work with IE9+

/**
 * Fire an event handler to the specified node. Event handlers can detect that the event was fired programatically
 * by testing for a 'synthetic=true' property on the event object
 * @param {HTMLNode} node The node to fire the event handler on.
 * @param {String} eventName The name of the event without the "on" (e.g., "focus")
 */
function fireEvent(node, eventName) {
    // Make sure we use the ownerDocument from the provided node to avoid cross-window problems
    var doc;
    if (node.ownerDocument) {
        doc = node.ownerDocument;
    } else if (node.nodeType == 9){
        // the node may be the document itself, nodeType 9 = DOCUMENT_NODE
        doc = node;
    } else {
        throw new Error("Invalid node passed to fireEvent: " + node.id);
    }

     if (node.dispatchEvent) {
        // Gecko-style approach (now the standard) takes more work
        var eventClass = "";

        // Different events have different event classes.
        // If this switch statement can't map an eventName to an eventClass,
        // the event firing is going to fail.
        switch (eventName) {
            case "click": // Dispatching of 'click' appears to not work correctly in Safari. Use 'mousedown' or 'mouseup' instead.
            case "mousedown":
            case "mouseup":
                eventClass = "MouseEvents";
                break;

            case "focus":
            case "change":
            case "blur":
            case "select":
                eventClass = "HTMLEvents";
                break;

            default:
                throw "fireEvent: Couldn't find an event class for event '" + eventName + "'.";
                break;
        }
        var event = doc.createEvent(eventClass);
        event.initEvent(eventName, true, true); // All events created as bubbling and cancelable.

        event.synthetic = true; // allow detection of synthetic events
        // The second parameter says go ahead with the default action
        node.dispatchEvent(event, true);
    } else  if (node.fireEvent) {
        // IE-old school style, you can drop this if you don't need to support IE8 and lower
        var event = doc.createEventObject();
        event.synthetic = true; // allow detection of synthetic events
        node.fireEvent("on" + eventName, event);
    }
};

Note that calling fireEvent(inputField, 'change'); does not mean it will actually change the input field. The typical use case for firing a change event is when you set a field programmatically and you want event handlers to be called since calling input.value="Something" won't trigger a change event.

None of the above answers are actually correct, because they do not follow the semantics when there are duplicated values.

For a query such as (from this duplicate):

SELECT * FROM t1 FULL OUTER JOIN t2 ON t1.Name = t2.Name;

The correct equivalent is:

SELECT t1.*, t2.*
FROM (SELECT name FROM t1 UNION  -- This is intentionally UNION to remove duplicates
      SELECT name FROM t2
     ) n LEFT JOIN
     t1
     ON t1.name = n.name LEFT JOIN
     t2
     ON t2.name = n.name;

If you need for this to work with NULL values (which may also be necessary), then use the NULL-safe comparison operator, <=> rather than =.

Because the answer is no longer valid with a more stable version of angular, I am posting a newer solution.

PHP Page: session.php

if (!isset($_SESSION))
{    
    session_start();
}    

$_SESSION['variable'] = "hello world";

$sessions = array();

$sessions['variable'] = $_SESSION['variable'];

header('Content-Type: application/json');
echo json_encode($sessions);

Send back only the session variables you want in Angular not all of them don't want to expose more than what is needed.

JS All Together

var app = angular.module('StarterApp', []);
app.controller("AppCtrl", ['$rootScope', 'Session', function($rootScope, Session) {      
    Session.then(function(response){
        $rootScope.session = response;
    });
}]);

 app.factory('Session', function($http) {    
    return $http.get('/session.php').then(function(result) {       
        return result.data; 
    });
}); 

• Do a simple get to get sessions using a factory.
• If you want to make it post to make the page not visible when you just go to it in the browser you can, I'm just simplifying it
• Add the factory to the controller
• I use rootScope because it is a session variable that I use throughout all my code.

HTML

Inside your html you can reference your session

<html ng-app="StarterApp">

<body ng-controller="AppCtrl">
{{ session.variable }}
</body>

You need to intent your current context to another activity first with startActivity. After that you can finish your current activity from where you redirect.

 Intent intent = new Intent(this, FirstActivity.class);// New activity
 intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
 startActivity(intent);
 finish(); // Call once you redirect to another activity

intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP) - Clears the activity stack. If you don't want to clear the activity stack. PLease don't use that flag then.

I experienced this issue after installing Cocoapods. Now happens everytime I update some pods. Solution I've found:

Go to terminal:

1) pod deintegrate
2) pod install

Also, check the item "Always Embed Swift Libraries" in your Build Settings. It should be "faded" indicating it is using the default configuration. If its set to a manual YES, hit delete over it to revert it to the default configuration. This stopped the behavior.

I was looking to do this also. I have a large tile (literally an image of a tile) image which I'd like to rotate by just roughly 15 degrees and have repeated. You can imagine the size of an image which would repeat seamlessly, rendering the 'image editing program' answer useless.

My solution was give the un-rotated (just one copy :) tile image to psuedo :before element - oversize it - repeat it - set the container overflow to hidden - and rotate the generated :before element using css3 transforms. Bosh!

I have the same issue, where I want to replace the white space in any pdf file to a dash -. But the files were in multiple sub-directories. So, I had to use os.walk(). In your case for multiple sub-directories, it could be something like this:

import os
for dpath, dnames, fnames in os.walk('/path/to/directory'):
    for f in fnames:
        os.chdir(dpath)
        if f.startswith('cheese_'):
            os.rename(f, f.replace('cheese_', ''))

my_data is a struct with name as a field and data[] is arry of structs, you are initializing each index. read following:

5.20 Designated Initializers:

In a structure initializer, specify the name of a field to initialize with .fieldname =' before the element value. For example, given the following structure,

struct point { int x, y; };

the following initialization

struct point p = { .y = yvalue, .x = xvalue };

is equivalent to

struct point p = { xvalue, yvalue };

Another syntax which has the same meaning, obsolete since GCC 2.5, is fieldname:', as shown here:

struct point p = { y: yvalue, x: xvalue };

You can also write:

my_data data[] = {
    { .name = "Peter" },
    { .name = "James" },
    { .name = "John" },
    { .name = "Mike" }
};

as:

my_data data[] = {
    [0] = { .name = "Peter" },
    [1] = { .name = "James" },
    [2] = { .name = "John" },
    [3] = { .name = "Mike" }
}; 

or:

my_data data[] = {
    [0].name = "Peter",
    [1].name = "James",
    [2].name = "John",
    [3].name = "Mike"
}; 

Second and third forms may be convenient as you don't need to write in order for example all of the above example are equivalent to:

my_data data[] = {
    [3].name = "Mike",
    [1].name = "James",
    [0].name = "Peter",
    [2].name = "John"
}; 

If you have multiple fields in your struct (for example, an int age), you can initialize all of them at once using the following:

my_data data[] = {
    [3].name = "Mike",
    [2].age = 40,
    [1].name = "James",
    [3].age = 23,
    [0].name = "Peter",
    [2].name = "John"
};

Here is an example how to set a request header in a jQuery Ajax call:

$.ajax({
  type: "POST",
  beforeSend: function(request) {
    request.setRequestHeader("Authority", authorizationToken);
  },
  url: "entities",
  data: "json=" + escape(JSON.stringify(createRequestObject)),
  processData: false,
  success: function(msg) {
    $("#results").append("The result =" + StringifyPretty(msg));
  }
});

The first parentheses are for, if you will, order of operations. The 'result' of the set of parentheses surrounding the function definition is the function itself which, indeed, the second set of parentheses executes.

As to why it's useful, I'm not enough of a JavaScript wizard to have any idea. :P

You should just grab the window by the title bar and snap it to the left side of your screen (close browser) then reopen the browser ans snap it to the top... problem is over.

in add method, why not using HashSet.add() to check duplicates instead of HashSet.consist(). HashSet.add() will return true if no duplicate and false otherwise.

If you don't mind using a bit of html, something like this should work.

from IPython.display import HTML, display

def display_table(data):
    html = "<table>"
    for row in data:
        html += "<tr>"
        for field in row:
            html += "<td><h4>%s</h4><td>"%(field)
        html += "</tr>"
    html += "</table>"
    display(HTML(html))

And then use it like this

data = [[1,2,3],[4,5,6],[7,8,9]]
display_table(data)

Three years after this question is posted and this is almost within reach. In fact, it's completely achievable in Firefox 1+, Chrome 1+, Safari 3+ and Opera 15+ using the CSS3 appearance property.

The result is radio elements that look like checkboxes:

input[type="radio"] {_x000D_
  -webkit-appearance: checkbox; /* Chrome, Safari, Opera */_x000D_
  -moz-appearance: checkbox;    /* Firefox */_x000D_
  -ms-appearance: checkbox;     /* not currently supported */_x000D_
}

<label><input type="radio" name="radio"> Checkbox 1</label>_x000D_
<label><input type="radio" name="radio"> Checkbox 2</label>

Note: this was eventually dropped from the CSS3 specification due to a lack of support and conformance from vendors. I'd recommend against implementing it unless you only need to support Webkit or Gecko based browsers.

How do I rename a specific column in pandas?

From v0.24+, to rename one (or more) columns at a time,

• DataFrame.rename() with axis=1 or axis='columns' (the axis argument was introduced in v0.21.

• Index.str.replace() for string/regex based replacement.

If you need to rename ALL columns at once,

• DataFrame.set_axis() method with axis=1. Pass a list-like sequence. Options are available for in-place modification as well.

rename with axis=1

df = pd.DataFrame('x', columns=['y', 'gdp', 'cap'], index=range(5))
df

   y gdp cap
0  x   x   x
1  x   x   x
2  x   x   x
3  x   x   x
4  x   x   x

With 0.21+, you can now specify an axis parameter with rename:

df.rename({'gdp':'log(gdp)'}, axis=1)
# df.rename({'gdp':'log(gdp)'}, axis='columns')
    
   y log(gdp) cap
0  x        x   x
1  x        x   x
2  x        x   x
3  x        x   x
4  x        x   x

(Note that rename is not in-place by default, so you will need to assign the result back.)

This addition has been made to improve consistency with the rest of the API. The new axis argument is analogous to the columns parameter—they do the same thing.

df.rename(columns={'gdp': 'log(gdp)'})

   y log(gdp) cap
0  x        x   x
1  x        x   x
2  x        x   x
3  x        x   x
4  x        x   x

rename also accepts a callback that is called once for each column.

df.rename(lambda x: x[0], axis=1)
# df.rename(lambda x: x[0], axis='columns')

   y  g  c
0  x  x  x
1  x  x  x
2  x  x  x
3  x  x  x
4  x  x  x

For this specific scenario, you would want to use

df.rename(lambda x: 'log(gdp)' if x == 'gdp' else x, axis=1)

Index.str.replace

Similar to replace method of strings in python, pandas Index and Series (object dtype only) define a ("vectorized") str.replace method for string and regex-based replacement.

df.columns = df.columns.str.replace('gdp', 'log(gdp)')
df
 
   y log(gdp) cap
0  x        x   x
1  x        x   x
2  x        x   x
3  x        x   x
4  x        x   x

The advantage of this over the other methods is that str.replace supports regex (enabled by default). See the docs for more information.

Passing a list to set_axis with axis=1

Call set_axis with a list of header(s). The list must be equal in length to the columns/index size. set_axis mutates the original DataFrame by default, but you can specify inplace=False to return a modified copy.

df.set_axis(['cap', 'log(gdp)', 'y'], axis=1, inplace=False)
# df.set_axis(['cap', 'log(gdp)', 'y'], axis='columns', inplace=False)

  cap log(gdp)  y

Method Chaining
Why choose set_axis when we already have an efficient way of assigning columns with df.columns = ...? As shown by Ted Petrou in this answer set_axis is useful when trying to chain methods.

Compare

# new for pandas 0.21+
df.some_method1()
  .some_method2()
  .set_axis()
  .some_method3()

Versus

# old way
df1 = df.some_method1()
        .some_method2()
df1.columns = columns
df1.some_method3()

The former is more natural and free flowing syntax.

Works with the wxWidgets library.

Believe it or not, you can actually use java.awt.Robot to "create an image containing pixels read from the screen." You can then write that image to a file on disk.

I just tried it, and the whole thing ends up like:

Rectangle screenRect = new Rectangle(Toolkit.getDefaultToolkit().getScreenSize());
BufferedImage capture = new Robot().createScreenCapture(screenRect);
ImageIO.write(capture, "bmp", new File(args[0]));

NOTE: This will only capture the primary monitor. See GraphicsConfiguration for multi-monitor support.

In case you are coming into this right now, I've just been through it today and can summarize where this stands. If you did not try this yet, some details here might help.

I think @Omid Ariyan's approach is the best way. Add the pre-commit and post-checkout scripts. DON'T forget to name them exactly the way Omid does and DON'T forget to make them executable. If you forget either of those, they have no effect and you run "git commit" over and over wondering why nothing happens :) Also, if you cut and paste out of the web browser, be careful that the quotation marks and ticks are not altered.

If you run the pre-commit script once (by running a git commit), then the file .permissions will be created. You can add it to the repository and I think it is unnecessary to add it over and over at the end of the pre-commit script. But it does not hurt, I think (hope).

There are a few little issues about the directory name and the existence of spaces in the file names in Omid's scripts. The spaces were a problem here and I had some trouble with the IFS fix. For the record, this pre-commit script did work correctly for me:

#!/bin/bash  

SELF_DIR=`git rev-parse --show-toplevel`
DATABASE=$SELF_DIR/.permissions

# Clear the permissions database file
> $DATABASE

echo -n "Backing-up file permissions..."

IFSold=$IFS
IFS=$'\n'
for FILE  in `git ls-files`
do
   # Save the permissions of all the files in the index
   echo $FILE";"`stat -c "%a;%U;%G" $FILE` >> $DATABASE
done
IFS=${IFSold}
# Add the permissions database file to the index
git add $DATABASE

echo "OK"

Now, what do we get out of this?

The .permissions file is in the top level of the git repo. It has one line per file, here is the top of my example:

$ cat .permissions
.gitignore;660;pauljohn;pauljohn
05.WhatToReport/05.WhatToReport.doc;664;pauljohn;pauljohn
05.WhatToReport/05.WhatToReport.pdf;664;pauljohn;pauljohn

As you can see, we have

filepath;perms;owner;group

In the comments about this approach, one of the posters complains that it only works with same username, and that is technically true, but it is very easy to fix it. Note the post-checkout script has 2 action pieces,

# Set the file permissions
chmod $PERMISSIONS $FILE
# Set the file owner and groups
chown $USER:$GROUP $FILE

So I am only keeping the first one, that's all I need. My user name on the Web server is indeed different, but more importantly you can't run chown unless you are root. Can run "chgrp", however. It is plain enough how to put that to use.

In the first answer in this post, the one that is most widely accepted, the suggestion is so use git-cache-meta, a script that is doing the same work that the pre/post hook scripts here are doing (parsing output from git ls-files). These scripts are easier for me to understand, the git-cache-meta code is rather more elaborate. It is possible to keep git-cache-meta in the path and write pre-commit and post-checkout scripts that would use it.

Spaces in file names are a problem with both of Omid's scripts. In the post-checkout script, you'll know you have the spaces in file names if you see errors like this

$ git checkout -- upload.sh
Restoring file permissions...chmod: cannot access  '04.StartingValuesInLISREL/Open': No such file or directory
chmod: cannot access 'Notebook.onetoc2': No such file or directory
chown: cannot access '04.StartingValuesInLISREL/Open': No such file or directory
chown: cannot access 'Notebook.onetoc2': No such file or directory

I'm checking on solutions for that. Here's something that seems to work, but I've only tested in one case

#!/bin/bash

SELF_DIR=`git rev-parse --show-toplevel`
DATABASE=$SELF_DIR/.permissions

echo -n "Restoring file permissions..."
IFSold=${IFS}
IFS=$
while read -r LINE || [[ -n "$LINE" ]];
do
   FILE=`echo $LINE | cut -d ";" -f 1`
   PERMISSIONS=`echo $LINE | cut -d ";" -f 2`
   USER=`echo $LINE | cut -d ";" -f 3`
   GROUP=`echo $LINE | cut -d ";" -f 4`

   # Set the file permissions
   chmod $PERMISSIONS $FILE
   # Set the file owner and groups
   chown $USER:$GROUP $FILE
done < $DATABASE
IFS=${IFSold}
echo "OK"

exit 0

Since the permissions information is one line at a time, I set IFS to $, so only line breaks are seen as new things.

I read that it is VERY IMPORTANT to set the IFS environment variable back the way it was! You can see why a shell session might go badly if you leave $ as the only separator.

You should be able to use join, which joins on the index as default. Given your desired result, you must use outer as the join type.

>>> df1.join(df2, how='outer')
            V1  V2
A 1/1/2012  12  15
  2/1/2012  14 NaN
  3/1/2012 NaN  21
B 1/1/2012  15  24
  2/1/2012   8   9
C 1/1/2012  17 NaN
  2/1/2012   9 NaN
D 1/1/2012 NaN   7
  2/1/2012 NaN  16

Signature: _.join(other, on=None, how='left', lsuffix='', rsuffix='', sort=False) Docstring: Join columns with other DataFrame either on index or on a key column. Efficiently Join multiple DataFrame objects by index at once by passing a list.

I needed to encode my parameters with ISO-8859-1, so the addingPercentEncoding() method doesn't work for me. I made a solution my self in Swift 4:

extension String {

  // Url percent encoding according to RFC3986 specifications
  // https://tools.ietf.org/html/rfc3986#section-2.1
  func urlPercentEncoded(withAllowedCharacters allowedCharacters: 
    CharacterSet, encoding: String.Encoding) -> String {
    var returnStr = ""

    // Compute each char seperatly
    for char in self {
      let charStr = String(char)
      let charScalar = charStr.unicodeScalars[charStr.unicodeScalars.startIndex]
      if allowedCharacters.contains(charScalar) == false,
        let bytesOfChar = charStr.data(using: encoding) {
        // Get the hexStr of every notAllowed-char-byte and put a % infront of it, append the result to the returnString
        for byte in bytesOfChar {
          returnStr += "%" + String(format: "%02hhX", byte as CVarArg)
        }
      } else {
        returnStr += charStr
      }
    }

    return returnStr
  }

}

Usage:

"aouäöü!".urlPercentEncoded(withAllowedCharacters: .urlQueryAllowed,
                                         encoding: .isoLatin1) 
// Results in -> "aou%E4%F6%FC!"

This is a working script that will scroll the page to the anchor. To setup just give the anchor link an id that matches the name attribute of the anchor that you want to scroll to.

<script>
jQuery(document).ready(function ($){ 
 $('a').click(function (){ 
  var id = $(this).attr('id');
  console.log(id);
  if ( id == 'cet' || id == 'protein' ) {
   $('html, body').animate({ scrollTop: $('[name="' + id + '"]').offset().top}, 'slow'); 
  }
 }); 
});
</script>

{
   <script type="text/javascript" src="@Url.Content("/Scripts/SomeScript.js")"></script>
   <script type="text/javascript" src="@Url.Content("/Scripts/AnotherScript.js")"></script>
}

You could use a pseudo element for this, and have your image on a hover:

I don't see what the problem with the timeit module is. This is probably the simplest way to do it.

import timeit
timeit.timeit(a, number=1)

Its also possible to send arguments to the functions. All you need is to wrap your function up using decorators. More explanation here: http://www.pythoncentral.io/time-a-python-function/

The only case where you might be interested in writing your own timing statements is if you want to run a function only once and are also want to obtain its return value.

The advantage of using the timeit module is that it lets you repeat the number of executions. This might be necessary because other processes might interfere with your timing accuracy. So, you should run it multiple times and look at the lowest value.

In my case, it was a missing line break that added unneeded parameters due to a bad copy and paste.

I followed a guide at https://pytorch.org/docs/stable/notes/windows.html#include-optional-components which looks like this when you copy it right here without any editing:

On the one hand Long is an object, while on the other hand long is a primitive type. In order to compare them you could get the primitive type out of the Long type:

public static void main(String[] args) {
    long a = 1111;
    Long b = 1113;

    if ((b!=null)&&
        (a == b.longValue())) 
    {
        System.out.println("Equals");
    } 
    else 
    {
        System.out.println("not equals");
    }
}

You are halfway there. Try:

In [4]: a[a < 0] = 0

In [5]: a
Out[5]: array([1, 2, 3, 0, 5])

The purpose of .iteritems() was to use less memory space by yielding one result at a time while looping. I am not sure why Python 3 version does not support iteritems()though it's been proved to be efficient than .items()

If you want to include a code that supports both the PY version 2 and 3,

try:
    iteritems
except NameError:
    iteritems = items

This can help if you deploy your project in some other system and you aren't sure about the PY version.

For enums, I test them only when they actually have methods in them. If it's a pure value-only enum like your example, I'd say don't bother.

But since you're keen on testing it, going with your second option is much better than the first. The problem with the first is that if you use an IDE, any renaming on the enums would also rename the ones in your test class.

If you don't have access to sysjobs table (someone elses server etc) you might be have or be allowed access to sysjobs_view

SELECT *
 from  msdb..sysjobs_view s 
 left join master.sys.syslogins l on s.owner_sid = l.sid

or

SELECT *, SUSER_SNAME(s.owner_sid) AS owner
 from  msdb..sysjobs_view s 

I don't work with contiguous ranges all the time. My solution for non-contiguous ranges is as follows (includes some code from other answers here):

Sub test_inters()
    Dim rng1 As Range
    Dim rng2 As Range
    Dim inters As Range

    Set rng2 = Worksheets("Gen2").Range("K7")
    Set rng1 = ExcludeCell(Worksheets("Gen2").Range("K6:K8"), rng2)

    If (rng2.Parent.name = rng1.Parent.name) Then
        Dim ints As Range
        MsgBox rng1.Address & vbCrLf _
        & rng2.Address & vbCrLf _

        For Each cell In rng1
            MsgBox cell.Address
            Set ints = Application.Intersect(cell, rng2)
            If (Not (ints Is Nothing)) Then
                MsgBox "Yes intersection"
            Else
                MsgBox "No intersection"
            End If
        Next cell
    End If
End Sub

As @AlexanderN pointed out, you can now delete App IDs.

1. In your Member Center go to the Certificates, Identifiers & Profiles section.
2. Go to Identifiers folder.
3. Select the App ID you want to delete and click Settings
4. Scroll down and click Delete.

Use

Console.WriteLine(String.Format("  {0:G17}", i));

That will give you all the 17 digits it have. By default, a Double value contains 15 decimal digits of precision, although a maximum of 17 digits is maintained internally. {0:R} will not always give you 17 digits, it will give 15 if the number can be represented with that precision.

which returns 15 digits if the number can be represented with that precision or 17 digits if the number can only be represented with maximum precision. There isn't any thing you can to do to make the the double return more digits that is the way it's implemented. If you don't like it do a new double class yourself...

.NET's double cant store any more digits than 17 so you cant see 6.89999999999999946709 in the debugger you would see 6.8999999999999995. Please provide an image to prove us wrong.

Using ng-pattern on the text field:

<input type="text"  ng-model="myText" name="inputName" ng-pattern="onlyNumbers">

Then include this on your controller

$scope.onlyNumbers = /^\d+$/;

If you check Thrown for Common Language Runtime Exception in the break when an exception window (Ctrl+Alt+E in Visual Studio), then the execution should break while you are debugging when the exception is thrown.

This will probably give you some insight into what is going on.

ok, so my problem was that I tried to install the package with yum which is the primary tool for getting, installing, deleting, querying, and managing Red Hat Enterprise Linux RPM software packages from official Red Hat software repositories, as well as other third-party repositories.

But I'm using ubuntu and The usual way to install packages on the command line in Ubuntu is with apt-get. so the right command was:

sudo apt-get install libstdc++.i686

Try editing your eclipse.ini file and add the following at the top

Keep the Screen On

First way:

getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);

Second way:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:keepScreenOn="true">
    ...
</RelativeLayout>

Keep the CPU On:

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

and

PowerManager powerManager = (PowerManager) getSystemService(POWER_SERVICE);
WakeLock wakeLock = powerManager.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "MyWakelockTag");
wakeLock.acquire();

To release the wake lock, call wakelock.release(). This releases your claim to the CPU. It's important to release a wake lock as soon as your app is finished using it to avoid draining the battery.

I wish to point out that if you use http://freegeoip.net/, you don't need to supply to it the IP address of the client's location. Just try these:

1) http://freegeoip.net/xml/

2) http://freegeoip.net/json/

3) http://freegeoip.net/csv/

However, I am unable to retrieve the information with AJAX calls, probably because of some cross-origin policy. Apparently they have not allowed public access to their system.

Here is another way you can change the selected option of a <select> element in javascript. You can use

document.getElementById('salesperson').selectedIndex=1;

Setting it to 1 will make the second element of the dropdown selected. The select element index start from 0.

Here is a sample code. Check if you can use this type of approach:

<html>
<head>
<script language="javascript">

function changeSelected() { 
document.getElementById('salesperson').selectedIndex=1;

} 

</script>
</head>
<body>
<form name="f1">

<select id="salesperson" > 
   <option value"">james</option>
   <option value"">john</option>  
</select> 
<input type="button" value="Change Selected" onClick="changeSelected();">

</form>
</body>
</html>

A python string is a list of characters. You can iterate over it right now!

Just open the R(software) and copy and paste

system("defaults write org.R-project.R force.LANG en_US.UTF-8")

Hope this will work fine or use the other method

open(on mac): Utilities/Terminal copy and paste

defaults write org.R-project.R force.LANG en_US.UTF-8

and close both terminal and R and reopen R.

There is a Headers property in the HttpRequestMessage class. You can add custom headers there, which will be sent with each HTTP request. The DefaultRequestHeaders in the HttpClient class, on the other hand, sets headers to be sent with each request sent using that client object, hence the name Default Request Headers.

Hope this makes things more clear, at least for someone seeing this answer in future.

This will get you a string array of all the resources:

System.Reflection.Assembly.GetExecutingAssembly().GetManifestResourceNames();

function getCustomHeaders()
{
    $headers = array();
    foreach($_SERVER as $key => $value)
    {
        if(preg_match("/^HTTP_X_/", $key))
            $headers[$key] = $value;
    }
    return $headers;
}

I use this function to get the custom headers, if the header starts from "HTTP_X_" we push in the array :)

It is part of the object literal syntax. The basic format is:

var obj = { field_name: "field value", other_field: 42 };

Then you can access these values with:

obj.field_name; // -> "field value"
obj["field_name"]; // -> "field value"

You can even have functions as values, basically giving you the methods of the object:

obj['func'] = function(a) { return 5 + a;};
obj.func(4);  // -> 9

Here's a quote from a recent blog post from Dare Obasanjo.

SQL databases are like automatic transmission and NoSQL databases are like manual transmission. Once you switch to NoSQL, you become responsible for a lot of work that the system takes care of automatically in a relational database system. Similar to what happens when you pick manual over automatic transmission. Secondly, NoSQL allows you to eke more performance out of the system by eliminating a lot of integrity checks done by relational databases from the database tier. Again, this is similar to how you can get more performance out of your car by driving a manual transmission versus an automatic transmission vehicle.

However the most notable similarity is that just like most of us can’t really take advantage of the benefits of a manual transmission vehicle because the majority of our driving is sitting in traffic on the way to and from work, there is a similar harsh reality in that most sites aren’t at Google or Facebook’s scale and thus have no need for a Bigtable or Cassandra.

To which I can add only that switching from MySQL, where you have at least some experience, to CouchDB, where you have no experience, means you will have to deal with a whole new set of problems and learn different concepts and best practices. While by itself this is wonderful (I am playing at home with MongoDB and like it a lot), it will be a cost that you need to calculate when estimating the work for that project, and brings unknown risks while promising unknown benefits. It will be very hard to judge if you can do the project on time and with the quality you want/need to be successful, if it's based on a technology you don't know.

Now, if you have on the team an expert in the NoSQL field, then by all means take a good look at it. But without any expertise on the team, don't jump on NoSQL for a new commercial project.

Update: Just to throw some gasoline in the open fire you started, here are two interesting articles from people on the SQL camp. :-)

While I am a big believer in reusing libraries, the org.apache.commons.io JAR is 174KB, which is noticably large for a mobile app.

If you download the source code and take a look at their FilenameUtils class, you can see there are a lot of extra utilities, and it does cope with Windows and Unix paths, which is all lovely.

However, if you just want a couple of static utility methods for use with Unix style paths (with a "/" separator), you may find the code below useful.

The removeExtension method preserves the rest of the path along with the filename. There is also a similar getExtension.

/**
 * Remove the file extension from a filename, that may include a path.
 * 
 * e.g. /path/to/myfile.jpg -> /path/to/myfile 
 */
public static String removeExtension(String filename) {
    if (filename == null) {
        return null;
    }

    int index = indexOfExtension(filename);

    if (index == -1) {
        return filename;
    } else {
        return filename.substring(0, index);
    }
}

/**
 * Return the file extension from a filename, including the "."
 * 
 * e.g. /path/to/myfile.jpg -> .jpg
 */
public static String getExtension(String filename) {
    if (filename == null) {
        return null;
    }

    int index = indexOfExtension(filename);

    if (index == -1) {
        return filename;
    } else {
        return filename.substring(index);
    }
}

private static final char EXTENSION_SEPARATOR = '.';
private static final char DIRECTORY_SEPARATOR = '/';

public static int indexOfExtension(String filename) {

    if (filename == null) {
        return -1;
    }

    // Check that no directory separator appears after the 
    // EXTENSION_SEPARATOR
    int extensionPos = filename.lastIndexOf(EXTENSION_SEPARATOR);

    int lastDirSeparator = filename.lastIndexOf(DIRECTORY_SEPARATOR);

    if (lastDirSeparator > extensionPos) {
        LogIt.w(FileSystemUtil.class, "A directory separator appears after the file extension, assuming there is no file extension");
        return -1;
    }

    return extensionPos;
}

If you're using a recent version of Bash (v3+), I suggest the Bash regex comparison operator =~, for example,

if [[ "$HOST" =~ ^user.* ]]; then
    echo "yes"
fi

To match this or that in a regex, use |, for example,

if [[ "$HOST" =~ ^user.*|^host1 ]]; then
    echo "yes"
fi

Note - this is 'proper' regular expression syntax.

• user* means use and zero-or-more occurrences of r, so use and userrrr will match.
• user.* means user and zero-or-more occurrences of any character, so user1, userX will match.
• ^user.* means match the pattern user.* at the begin of $HOST.

If you're not familiar with regular expression syntax, try referring to this resource.

This error occures when you try to refer to a null object instance. I can`t tell you what causes this error by your given information, but you can debug it easily in your IDE. I strongly recommend you that use exception handling to avoid unexpected program behavior.

The log file is not visible because the slf4j configuration file location needs to passed to the java run command using the following arguments .(e.g.)

-Dlogging.config={file_location}\log4j2.xml 

or this:

-Dlog4j.configurationFile={file_location}\log4j2.xml

Welcome to Java! This Nodes are like a blocks, they must be assembled to do amazing things! In this particular case, your nodes can represent a list, a linked list, You can see an example here:

public class ItemLinkedList {
    private ItemInfoNode head;
    private ItemInfoNode tail;
    private int size = 0;

    public int getSize() {
        return size;
    }

    public void addBack(ItemInfo info) {
        size++;
        if (head == null) {
            head = new ItemInfoNode(info, null, null);
            tail = head;
        } else {
            ItemInfoNode node = new ItemInfoNode(info, null, tail);
            this.tail.next =node;
            this.tail = node;
        }
    }

    public void addFront(ItemInfo info) {
        size++;
        if (head == null) {
            head = new ItemInfoNode(info, null, null);
            tail = head;
        } else {
            ItemInfoNode node = new ItemInfoNode(info, head, null);
            this.head.prev = node;
            this.head = node;
        }
    }

    public ItemInfo removeBack() {
        ItemInfo result = null;
        if (head != null) {
            size--;
            result = tail.info;
            if (tail.prev != null) {
                tail.prev.next = null;
                tail = tail.prev;
            } else {
                head = null;
                tail = null;
            }
        }
        return result;
    }

    public ItemInfo removeFront() {
        ItemInfo result = null;
        if (head != null) {
            size--;
            result = head.info;
            if (head.next != null) {
                head.next.prev = null;
                head = head.next;
            } else {
                head = null;
                tail = null;
            }
        }
        return result;
    }

    public class ItemInfoNode {

        private ItemInfoNode next;
        private ItemInfoNode prev;
        private ItemInfo info;

        public ItemInfoNode(ItemInfo info, ItemInfoNode next, ItemInfoNode prev) {
            this.info = info;
            this.next = next;
            this.prev = prev;
        }

        public void setInfo(ItemInfo info) {
            this.info = info;
        }

        public void setNext(ItemInfoNode node) {
            next = node;
        }

        public void setPrev(ItemInfoNode node) {
            prev = node;
        }

        public ItemInfo getInfo() {
            return info;
        }

        public ItemInfoNode getNext() {
            return next;
        }

        public ItemInfoNode getPrev() {
            return prev;
        }
    }
}

EDIT:

Declare ItemInfo as this:

public class ItemInfo {
    private String name;
    private String rfdNumber;
    private double price;
    private String originalPosition;

    public ItemInfo(){
    }

    public ItemInfo(String name, String rfdNumber, double price, String originalPosition) {
        this.name = name;
        this.rfdNumber = rfdNumber;
        this.price = price;
        this.originalPosition = originalPosition;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getRfdNumber() {
        return rfdNumber;
    }

    public void setRfdNumber(String rfdNumber) {
        this.rfdNumber = rfdNumber;
    }

    public double getPrice() {
        return price;
    }

    public void setPrice(double price) {
        this.price = price;
    }

    public String getOriginalPosition() {
        return originalPosition;
    }

    public void setOriginalPosition(String originalPosition) {
        this.originalPosition = originalPosition;
    }
}

Then, You can use your nodes inside the linked list like this:

public static void main(String[] args) {
    ItemLinkedList list = new ItemLinkedList();
    for (int i = 1; i <= 10; i++) {
        list.addBack(new ItemInfo("name-"+i, "rfd"+i, i, String.valueOf(i)));

    }
    while (list.size() > 0){
        System.out.println(list.removeFront().getName());
    }
}

Why so complicated? When you can do:

var loadTime = window.performance.timing.domContentLoadedEventEnd- window.performance.timing.navigationStart;

If you need more times check out the window.performance object:

console.log(window.performance);

Will show you the timing object:

connectEnd                 Time when server connection is finished.
connectStart               Time just before server connection begins.
domComplete                Time just before document readiness completes.
domContentLoadedEventEnd   Time after DOMContentLoaded event completes.
domContentLoadedEventStart Time just before DOMContentLoaded starts.
domInteractive             Time just before readiness set to interactive.
domLoading                 Time just before readiness set to loading.
domainLookupEnd            Time after domain name lookup.
domainLookupStart          Time just before domain name lookup.
fetchStart                 Time when the resource starts being fetched.
loadEventEnd               Time when the load event is complete.
loadEventStart             Time just before the load event is fired.
navigationStart            Time after the previous document begins unload.
redirectCount              Number of redirects since the last non-redirect.

More Info

Given your example, you need to add the following import in your main.main class:

import second.second;

Some bonus advice, make sure you titlecase your class names as that is a Java standard. So your example Main class will have the structure:

package main;  //lowercase package names
public class Main //titlecase class names
{
    //Main class content
}

I don't know why but i just renamed my source file COLARR.C to colarr.c and the error vanished! probably you need this

sudo apt-get install g++

You shouldn't need a $watch. Just bind to resize event on window:

DEMO

'use strict';

var app = angular.module('plunker', []);

app.directive('myDirective', ['$window', function ($window) {

     return {
        link: link,
        restrict: 'E',
        template: '<div>window size: {{width}}px</div>'
     };

     function link(scope, element, attrs){

       scope.width = $window.innerWidth;

       angular.element($window).bind('resize', function(){

         scope.width = $window.innerWidth;

         // manuall $digest required as resize event
         // is outside of angular
         scope.$digest();
       });

     }

 }]);

You need a special type of function known as a table valued function. Below is a somewhat long-winded example that builds a date dimension for a data warehouse. Note the returns clause that defines a table structure. You can insert anything into the table variable (@DateHierarchy in this case) that you want, including building a temporary table and copying the contents into it.

if object_id ('ods.uf_DateHierarchy') is not null
    drop function ods.uf_DateHierarchy
go

create function ods.uf_DateHierarchy (
       @DateFrom datetime
      ,@DateTo   datetime
) returns @DateHierarchy table (
        DateKey           datetime

Unless somefunction is a very bad coded legacy function, you shouldn't need what you're asking.

Use multiple except clause to handle in different ways different exceptions:

try:
    someFunction()
except ValueError:
    # do something
except ZeroDivision:
    # do something else

The main point is that you shouldn't catch generic exception, but only the ones that you need to. I'm sure that you don't want to shadow unexpected errors or bugs.

If you want to restrict valid input to integer values between 1 and 100, this will do it:

^([1-9]|[1-9][0-9]|100)$

Explanation:

1. ^ = start of input
2. () = multiple options to match
3. First argument [1-9] - matches any entries between 1 and 9
4. | = OR argument separator
5. Second Argument [1-9][0-9] - matches entries between 10 and 99
6. Last Argument 100 - Self explanatory - matches entries of 100

This WILL NOT ACCEPT: 1. Zero - 0 2. Any integer preceded with a zero - 01, 021, 001 3. Any integer greater than 100

Hope this helps!

The function I used:

function cutAfter($string, $len = 30, $append = '...') {
        return (strlen($string) > $len) ? 
          substr($string, 0, $len - strlen($append)) . $append : 
          $string;
}

See it in action.

Basically in this case, System.Data.OracleClient need access to some of the oracle dll which are not part of .Net. Solutions:

• Install Oracle Client , and add bin location to Path environment varaible of windows OR
• Copy oraociicus10.dll (Basic-Lite version) or aociei10.dll (Basic version), oci.dll, orannzsbb10.dll and oraocci10.dll from oracle client installable folder to bin folder of application so that application is able to find required dll

System.ArgumentNullException: Value cannot be null. Parameter name: value

This error message is not very helpful!

You can get this error in many different ways. The error may not always be with the parameter name: value. It could be whatever parameter name is being passed into a function.

As a generic way to solve this, look at the stack trace or call stack:

Test method GetApiModel threw exception: 
System.ArgumentNullException: Value cannot be null.
Parameter name: value
    at Newtonsoft.Json.JsonConvert.DeserializeObject(String value, Type type, JsonSerializerSettings settings)

You can see that the parameter name value is the first parameter for DeserializeObject. This lead me to check my AutoMapper mapping where we are deserializing a JSON string. That string is null in my database.

You can change the code to check for null.

Depending on what you want to do you could do this:

template<typename Base, typename T>
inline bool instanceof(const T*) {
    return std::is_base_of<Base, T>::value;
}

Use:

if (instanceof<BaseClass>(ptr)) { ... }

However, this purely operates on the types as known by the compiler.

Edit:

This code should work for polymorphic pointers:

template<typename Base, typename T>
inline bool instanceof(const T *ptr) {
    return dynamic_cast<const Base*>(ptr) != nullptr;
}

Example: http://cpp.sh/6qir

Cut/Paste of a section is another quick way (and easy to remember).

You can try the following:

from haversine import haversine
haversine((45.7597, 4.8422),(48.8567, 2.3508), unit='mi')
243.71209416020253

Your method implementation is ambiguous, try the following , edited your code a little bit and used HttpStatus.NO_CONTENT i.e 204 No Content as in place of HttpStatus.OK

The server has fulfilled the request but does not need to return an entity-body, and might want to return updated metainformation. The response MAY include new or updated metainformation in the form of entity-headers, which if present SHOULD be associated with the requested variant.

Any value of T will be ignored for 204, but not for 404

  public ResponseEntity<?> taxonomyPackageExists( @PathVariable final String key ) {
            LOG.debug( "taxonomyPackageExists queried with key: {0}", key ); //$NON-NLS-1$
            final TaxonomyKey taxonomyKey = TaxonomyKey.fromString( key );
            LOG.debug( "Taxonomy key created: {0}", taxonomyKey ); //$NON-NLS-1$

            if ( this.xbrlInstanceValidator.taxonomyPackageExists( taxonomyKey ) ) {
                LOG.debug( "Taxonomy package with key: {0} exists.", taxonomyKey ); //$NON-NLS-1$
                 return new ResponseEntity<T>(HttpStatus.NO_CONTENT);
            } else {
               LOG.debug( "Taxonomy package with key: {0} does NOT exist.", taxonomyKey ); //$NON-NLS-1$
                return new ResponseEntity<T>( HttpStatus.NOT_FOUND );
            }

    }

When you compare two DataFrames, you must ensure that the number of records in the first DataFrame matches with the number of records in the second DataFrame. In our example, each of the two DataFrames had 4 records, with 4 products and 4 prices.

If, for example, one of the DataFrames had 5 products, while the other DataFrame had 4 products, and you tried to run the comparison, you would get the following error:

ValueError: Can only compare identically-labeled Series objects

this should work

import pandas as pd
import numpy as np

firstProductSet = {'Product1': ['Computer','Phone','Printer','Desk'],
                   'Price1': [1200,800,200,350]
                   }
df1 = pd.DataFrame(firstProductSet,columns= ['Product1', 'Price1'])


secondProductSet = {'Product2': ['Computer','Phone','Printer','Desk'],
                    'Price2': [900,800,300,350]
                    }
df2 = pd.DataFrame(secondProductSet,columns= ['Product2', 'Price2'])


df1['Price2'] = df2['Price2'] #add the Price2 column from df2 to df1

df1['pricesMatch?'] = np.where(df1['Price1'] == df2['Price2'], 'True', 'False')  #create new column in df1 to check if prices match
df1['priceDiff?'] = np.where(df1['Price1'] == df2['Price2'], 0, df1['Price1'] - df2['Price2']) #create new column in df1 for price diff 
print (df1)

Not a regexp expert, but I think you could use a negative lookahead from the start, e.g. ^(?!foo).*$ shouldn't match anything starting with foo.

<input type="text" disabled="disabled" />

To receive a pure JSON string, without it being wrapped into an XML, you have to write the JSON string directly to the HttpResponse and change the WebMethod return type to void.

    [System.Web.Script.Services.ScriptService]
    public class WebServiceClass : System.Web.Services.WebService {
        [WebMethod]
        public void WebMethodName()
        {
            HttpContext.Current.Response.Write("{property: value}");
        }
    }
