Here's my take on this:

if(object_id(N'[dbo].[fn_Nth_Pos]', N'FN')) is not null
    drop function [dbo].[fn_Nth_Pos];
GO
CREATE FUNCTION [dbo].[fn_Nth_Pos]
(
    @find char, --char to find
    @search varchar(max), --string to process   
    @nth int --occurrence   
)
RETURNS int
AS
BEGIN
    declare @pos int --position of nth occurrence
    --init
    set @pos = 0

    while(@nth > 0)
    begin       
        set @pos = charindex(@find,@search,@pos+1)
        set @nth = @nth - 1
    end 

    return @pos
END
GO

--EXAMPLE
declare @files table(name varchar(max));

insert into @files(name) values('abc_1_2_3_4.gif');
insert into @files(name) values('zzz_12_3_3_45.gif');

select
    f.name,
    dbo.fn_Nth_Pos('_', f.name, 1) as [1st],
    dbo.fn_Nth_Pos('_', f.name, 2) as [2nd],
    dbo.fn_Nth_Pos('_', f.name, 3) as [3rd],
    dbo.fn_Nth_Pos('_', f.name, 4) as [4th]
from 
    @files f;

If you dont want your local changes, then do below command to ignore(delete permanently) the local changes.

• If its unstaged changes, then do checkout (git checkout <filename> or git checkout -- .)
• If its staged changes, then first do reset (git reset <filename> or git reset) and then do checkout (git checkout <filename> or git checkout -- .)
• If it is untracted files/folders (newly created), then do clean (git clean -fd)

If you dont want to loose your local changes, then stash it and do pull or rebase. Later merge your changes from stash.

• Do git stash, and then get latest changes from repo git pull orign master or git rebase origin/master, and then merge your changes from stash git stash pop stash@{0}

First, you can't make a class that extends from String, because String is a final class. And java manage Strings differently from other classes so only with String you can do

String s = "Polish";

But whit your class you have to invoke the constructor. So, that code is fine.

 mkdir -p `dirname /nosuchdirectory/hi.txt` && cp -r urls-resume /nosuchdirectory/hi.txt

Use Not IsNull(Fields!W_O_Count.Value)

If it is possible in your case, you could make your methods method1(arg1) ... method7() protected instead of private so they could be accesible from test class within the same package. Then you can simply test all theese methods separately.

I believe your code is analogous to the following, and you should not have expected the value to have changed for the same reason it wouldn't here:

 public static void Main()
 {
     StringWrapper testVariable = new StringWrapper("before passing");
     Console.WriteLine(testVariable);
     TestI(testVariable);
     Console.WriteLine(testVariable);
 }

 public static void TestI(StringWrapper testParameter)
 {
     testParameter = new StringWrapper("after passing");

     // this will change the object that testParameter is pointing/referring
     // to but it doesn't change testVariable unless you use a reference
     // parameter as indicated in other answers
 }

>>> isinstance([0, 10, 20, 30], list)
True
>>> isinstance(50, list)
False

To support any type of sequence, check collections.Sequence instead of list.

note: isinstance also supports a tuple of classes, check type(x) in (..., ...) should be avoided and is unnecessary.

You may also wanna check not isinstance(x, (str, unicode))

I know when you said "contents" you didn't mean this, but if you want to find all the values of all the attributes of a webelement this is a pretty nifty way to do that with javascript in python:

everything = b.execute_script(
    'var element = arguments[0];'
    'var attributes = {};'
    'for (index = 0; index < element.attributes.length; ++index) {'
    '    attributes[element.attributes[index].name] = element.attributes[index].value };'
    'var properties = [];'
    'properties[0] = attributes;'
    'var element_text = element.textContent;'
    'properties[1] = element_text;'
    'var styles = getComputedStyle(element);'
    'var computed_styles = {};'
    'for (index = 0; index < styles.length; ++index) {'
    '    var value_ = styles.getPropertyValue(styles[index]);'
    '    computed_styles[styles[index]] = value_ };'
    'properties[2] = computed_styles;'
    'return properties;', element)

you can also get some extra data with element.__dict__.

I think this is about all the data you'd ever want to get from a webelement.

You could make the variables public fields:

  public int width;
  public int height;

  DrawFrame() {
    this.width = 400;
    this.height = 400;
  }

You could then access the variables like so:

DrawFrame frame = new DrawFrame();
int theWidth = frame.width;
int theHeight = frame.height;

A better solution, however, would be to make the variables private fields add two accessor methods to your class, keeping the data in the DrawFrame class encapsulated:

 private int width;
 private int height;

 DrawFrame() {
    this.width = 400;
    this.height = 400;
 }

  public int getWidth() {
     return this.width;
  }

  public int getHeight() {
     return this.height;
  }

Then you can get the width/height like so:

  DrawFrame frame = new DrawFrame();
  int theWidth = frame.getWidth();
  int theHeight = frame.getHeight();

I strongly suggest you use the latter method.

Some great examples of recursion are found in functional programming languages. In functional programming languages (Erlang, Haskell, ML/OCaml/F#, etc.), it's very common to have any list processing use recursion.

When dealing with lists in typical imperative OOP-style languages, it's very common to see lists implemented as linked lists ([item1 -> item2 -> item3 -> item4]). However, in some functional programming languages, you find that lists themselves are implemented recursively, where the "head" of the list points to the first item in the list, and the "tail" points to a list containing the rest of the items ([item1 -> [item2 -> [item3 -> [item4 -> []]]]]). It's pretty creative in my opinion.

This handling of lists, when combined with pattern matching, is VERY powerful. Let's say I want to sum a list of numbers:

let rec Sum numbers =
    match numbers with
    | [] -> 0
    | head::tail -> head + Sum tail

This essentially says "if we were called with an empty list, return 0" (allowing us to break the recursion), else return the value of head + the value of Sum called with the remaining items (hence, our recursion).

For example, I might have a list of URLs, I think break apart all the URLs each URL links to, and then I reduce the total number of links to/from all URLs to generate "values" for a page (an approach that Google takes with PageRank and that you can find defined in the original MapReduce paper). You can do this to generate word counts in a document also. And many, many, many other things as well.

You can extend this functional pattern to any type of MapReduce code where you can taking a list of something, transforming it, and returning something else (whether another list, or some zip command on the list).

In my case, the request was getting timed out. So all you need to do is to increase the time out while creating the HttpClient.

HttpClient client = new HttpClient();

client.Timeout = TimeSpan.FromMinutes(5);

The elevation style property on Android does not work unless backgroundColor has been specified for the element.

Android - elevation style property does not work without backgroundColor

Example:

{
  shadowColor: 'black',
  shadowOpacity: 0.26,
  shadowOffset: { width: 0, height: 2},
  shadowRadius: 10,
  elevation: 3,
  backgroundColor: 'white'
}

var option = driver.FindElement(By.Id("employmentType"));
        var selectElement = new SelectElement(option);
        Task.Delay(3000).Wait();
        selectElement.SelectByIndex(2);
        Console.Read();

Just to update all, after some deliberations, I have decided to use Async Http Client instead to solve my earlier problem. The library allows a cleaner approach (to me) to manipulate HTTP responses especially in cases where JSON objects are returned in all scenarios/HTTP statuses.

protected void getLogin() {

    EditText username = (EditText) findViewById(R.id.username); 
    EditText password = (EditText) findViewById(R.id.password); 

    RequestParams params = new RequestParams();
    params.put("username", username.getText().toString());
    params.put("password", password.getText().toString());

    RestClient.post(getHost() + "api/v1/auth/login", params,
            new JsonHttpResponseHandler() {

        @Override
        public void onSuccess(int statusCode, Header[] headers,
                JSONObject response) {

            try {

                //process JSONObject obj 
                Log.w("myapp","success status code..." + statusCode);

            } catch (JSONException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        }

        @Override
        public void onFailure(int statusCode, Header[] headers,
                Throwable throwable, JSONObject errorResponse) {
            Log.w("myapp", "failure status code..." + statusCode);


            try {
                //process JSONObject obj
                Log.w("myapp", "error ..."  + errorResponse.getString("message").toString());
            } catch (JSONException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        }
    });
}

I don't think that this is safe because e.g. the "=" character is used in raw base 64 and is also used in differentiating the parameters from the values in an HTTP GET.

Somehow python 3 came back (after some updates?) and is causing big issues with apt updates, so I've decided to remove python 3 completely from the alternatives:

root:~# python -V
Python 3.5.2

root:~# update-alternatives --config python
There are 2 choices for the alternative python (providing /usr/bin/python).

  Selection    Path                Priority   Status

  2            /usr/bin/python3.5   3         manual mode


root:~# update-alternatives --remove python /usr/bin/python3.5

root:~# update-alternatives --config python
There is 1 choice for the alternative python (providing /usr/bin/python).

    Selection    Path                Priority   Status

This one works for me:

html

<ul>
    <li> name here </li>
</ul>

CSS

ul li::before {
    content: url(../images/check.png);
}

Im working with mysql and registered with root user, the solution that work for me is the following:

mysql > SET SESSION sql_mode=(SELECT REPLACE(@@sql_mode,'ONLY_FULL_GROUP_BY',''));

An Ad-Hoc Query is a query that cannot be determined prior to the moment the query is issued. It is created in order to get information when need arises and it consists of dynamically constructed SQL which is usually constructed by desktop-resident query tools.

Check: http://www.learn.geekinterview.com/data-warehouse/dw-basics/what-is-an-ad-hoc-query.html

The LOAD DATA INFILE statement reads rows from a text file into a table at a very high speed.

LOAD DATA INFILE '/tmp/test.txt' 
INTO TABLE test
FIELDS TERMINATED BY ','
LINES STARTING BY 'xxx';

If the data file looks like this:

xxx"abc",1
something xxx"def",2
"ghi",3

The resulting rows will be ("abc",1) and ("def",2). The third row in the file is skipped because it does not contain the prefix.

LOAD DATA INFILE 'data.txt'
INTO TABLE tbl_name
FIELDS TERMINATED BY ','
ENCLOSED BY '"'
LINES TERMINATED BY '\r\n'

You can also load data files by using the mysqlimport utility; it operates by sending a LOAD DATA INFILE statement to the server

mysqlimport -u root -ptmppassword --local test employee.txt

test.employee: Records: 3  Deleted: 0  Skipped: 0  Warnings: 0

Perhaps using the textDecoder will be sufficient.

Not supported in IE though.

var decoder = new TextDecoder('utf-8'),
    decodedMessage;

decodedMessage = decoder.decode(message.data);

Handling non-UTF8 text

In this example, we decode the Russian text "??????, ???!", which means "Hello, world." In our TextDecoder() constructor, we specify the Windows-1251 character encoding, which is appropriate for Cyrillic script.

    let win1251decoder = new TextDecoder('windows-1251');
    let bytes = new Uint8Array([207, 240, 232, 226, 229, 242, 44, 32, 236, 232, 240, 33]);
    console.log(win1251decoder.decode(bytes)); // ??????, ???!

The interface for the TextDecoder is described here.

Retrieving a byte array from a string is equally simpel:

const decoder = new TextDecoder();
const encoder = new TextEncoder();

const byteArray = encoder.encode('Größe');
// converted it to a byte array

// now we can decode it back to a string if desired
console.log(decoder.decode(byteArray));

If you have it in a different encoding then you must compensate for that upon encoding. The parameter in the constructor for the TextEncoder is any one of the valid encodings listed here.

For IIS 7.5+ you can use IIS CORS Module: https://www.iis.net/downloads/microsoft/iis-cors-module

Your web.config should be something like this:

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <system.webServer>
        <cors enabled="true" failUnlistedOrigins="true">
            <add origin="http://localhost:1506">
                <allowMethods>                    
                    <add method="GET" />
                    <add method="HEAD" />

                    <add method="PUT" /> 
                    <add method="DELETE" /> 
                </allowMethods>
            </add>

                </allowMethods>
            </add>
        </cors>
    </system.webServer>

in my case app want to use iCloud services, but in distr. provision profile wasn't set iCloud enabled. turn it on and refresh profile.

If you are using JetBrains editors like IntelliJ IDEA, PhpStorm, WebStorm etc. Use the following settings in Settings > File Watchers.

1. Convert style.scss to style.css set the arguments

   --no-cache --update $FileName$:$FileNameWithoutExtension$.css
   

   and output paths to refresh

   $FileNameWithoutExtension$.css
   

2. Convert style.scss to compressed style.min.css set the arguments

   --no-cache --update $FileName$:$FileNameWithoutExtension$.min.css --style compressed
   

   and output paths to refresh

   $FileNameWithoutExtension$.min.css
   

From the official Spring documentation:

General interface that represents binding results. Extends the interface for error registration capabilities, allowing for a Validator to be applied, and adds binding-specific analysis and model building.

Serves as result holder for a DataBinder, obtained via the DataBinder.getBindingResult() method. BindingResult implementations can also be used directly, for example to invoke a Validator on it (e.g. as part of a unit test).

If you would like to add vector to itself both popular solutions will fail:

std::vector<std::string> v, orig;

orig.push_back("first");
orig.push_back("second");

// BAD:
v = orig;
v.insert(v.end(), v.begin(), v.end());
// Now v contains: { "first", "second", "", "" }

// BAD:
v = orig;
std::copy(v.begin(), v.end(), std::back_inserter(v));
// std::bad_alloc exception is generated

// GOOD, but I can't guarantee it will work with any STL:
v = orig;
v.reserve(v.size()*2);
v.insert(v.end(), v.begin(), v.end());
// Now v contains: { "first", "second", "first", "second" }

// GOOD, but I can't guarantee it will work with any STL:
v = orig;
v.reserve(v.size()*2);
std::copy(v.begin(), v.end(), std::back_inserter(v));
// Now v contains: { "first", "second", "first", "second" }

// GOOD (best):
v = orig;
v.insert(v.end(), orig.begin(), orig.end()); // note: we use different vectors here
// Now v contains: { "first", "second", "first", "second" }

Turns out that the post (or rather the whole table) was locked by the very same connection that I tried to update the post with.

I had a opened record set of the post that was created by:

Set RecSet = Conn.Execute()

This type of recordset is supposed to be read-only and when I was using MS Access as database it did not lock anything. But apparently this type of record set did lock something on MS SQL Server 2012 because when I added these lines of code before executing the UPDATE SQL statement...

RecSet.Close
Set RecSet = Nothing

...everything worked just fine.

So bottom line is to be careful with opened record sets - even if they are read-only they could lock your table from updates.

The closest thing in C# 3.0, is that you can use a constructor to initialize properties:

Stuff.Elements.Foo foo = new Stuff.Elements.Foo() {Name = "Bob Dylan", Age = 68, Location = "On Tour", IsCool = true}

The current answers suggest a workaround but it's bugged me why this doesn't exist, so I've created a babel plugin which does this.

Install it using:

npm i --save-dev babel-plugin-wildcard

then add it to your .babelrc with:

{
    "plugins": ["wildcard"]
}

see the repo for detailed install info

This allows you to do this:

import * as Things from './lib/things';

// Do whatever you want with these :D
Things.ThingA;
Things.ThingB;
Things.ThingC;

again, the repo contains further information on what exactly it does, but doing it this way avoids creating index.js files and also happens at compile-time to avoid doing readdirs at runtime.

Also with a newer version you can do exactly like your example:

 import { ThingsA, ThingsB, ThingsC } from './lib/things/*';

works the same as the above.

Assuming your page is available under "http://example.com"

from selenium import webdriver
from selenium.webdriver.common.keys import Keys

driver = webdriver.Firefox()
driver.get("http://example.com")

Select element by id:

inputElement = driver.find_element_by_id("a1")
inputElement.send_keys('1')

Now you can simulate hitting ENTER:

inputElement.send_keys(Keys.ENTER)

or if it is a form you can submit:

inputElement.submit() 

Hi I'm also relatively new but I can give you basic help.

1. To switch to another branch use "Checkout". Just click on your branch and then on the button "checkout" at the top.

UPDATE 12.01.2016:

The bold line is the current branch.

You can also just double click a branch to use checkout.

2. Your first answer I think depends on the repository you use (like github or bitbucket). Maybe the "Show hosted repository"-Button can help you (Left panel, bottom, right button = database with cog)

To get the first and the last day of the year, one can use the CONCAT function. The resulting value may be cast to any type.

I found that subplots_adjust(hspace = 0.001) is what ended up working for me. When I use space = None, there is still white space between each plot. Setting it to something very close to zero however seems to force them to line up. What I've uploaded here isn't the most elegant piece of code, but you can see how the hspace works.

import numpy as np
import matplotlib.pyplot as plt
import matplotlib.ticker as tic

fig = plt.figure()

x = np.arange(100)
y = 3.*np.sin(x*2.*np.pi/100.)

for i in range(5):
    temp = 510 + i
    ax = plt.subplot(temp)
    plt.plot(x,y)
    plt.subplots_adjust(hspace = .001)
    temp = tic.MaxNLocator(3)
    ax.yaxis.set_major_locator(temp)
    ax.set_xticklabels(())
    ax.title.set_visible(False)

Please use json.Decoder instead of json.Unmarshal.

func test(rw http.ResponseWriter, req *http.Request) {
    decoder := json.NewDecoder(req.Body)
    var t test_struct

    if err != nil {
        panic(err)
    }
    log.Println(t.Test)
}

This is the format of /etc/crontab:

# .---------------- minute (0 - 59)
# |  .------------- hour (0 - 23)
# |  |  .---------- day of month (1 - 31)
# |  |  |  .------- month (1 - 12) OR jan,feb,mar,apr ...
# |  |  |  |  .---- day of week (0 - 6) (Sunday=0 or 7) OR sun,mon,tue,wed,thu,fri,sat
# |  |  |  |  |
# *  *  *  *  * user-name  command to be executed

I recommend copy & pasting that into the top of your crontab file so that you always have the reference handy. RedHat systems are setup that way by default.

To run something every minute:

* * * * * username /var/www/html/a.php

To run something at midnight of every day:

0 0 * * * username /var/www/html/reset.php

You can either include /usr/bin/php in the command to run, or you can make the php scripts directly executable:

chmod +x file.php

Start your php file with a shebang so that your shell knows which interpreter to use:

#!/usr/bin/php
<?php
// your code here

It is simpler than I thought it would be.

To set the font size of the x-axis ticks:

x_ticks=['x tick 1','x tick 2','x tick 3']
ax.set_xticklabels(x_ticks, rotation=0, fontsize=8)

To do it for the y-axis ticks:

y_ticks=['y tick 1','y tick 2','y tick 3']
ax.set_yticklabels(y_ticks, rotation=0, fontsize=8)

The arguments rotation and fontsize can easily control what I was after.

Beware of sample for splitting if you look for reproducible results. If your data changes even slightly, the split will vary even if you use set.seed. For example, imagine the sorted list of IDs in you data is all the numbers between 1 and 10. If you just dropped one observation, say 4, sampling by location would yield a different results because now 5 to 10 all moved places.

An alternative method is to use a hash function to map IDs into some pseudo random numbers and then sample on the mod of these numbers. This sample is more stable because assignment is now determined by the hash of each observation, and not by its relative position.

For example:

require(openssl)  # for md5
require(data.table)  # for the demo data

set.seed(1)  # this won't help `sample`

population <- as.character(1e5:(1e6-1))  # some made up ID names

N <- 1e4  # sample size

sample1 <- data.table(id = sort(sample(population, N)))  # randomly sample N ids
sample2 <- sample1[-sample(N, 1)]  # randomly drop one observation from sample1

# samples are all but identical
sample1
sample2
nrow(merge(sample1, sample2))

[1] 9999

# row splitting yields very different test sets, even though we've set the seed
test <- sample(N-1, N/2, replace = F)

test1 <- sample1[test, .(id)]
test2 <- sample2[test, .(id)]
nrow(test1)

[1] 5000

nrow(merge(test1, test2))

[1] 2653

# to fix that, we can use some hash function to sample on the last digit

md5_bit_mod <- function(x, m = 2L) {
  # Inputs: 
  #  x: a character vector of ids
  #  m: the modulo divisor (modify for split proportions other than 50:50)
  # Output: remainders from dividing the first digit of the md5 hash of x by m
  as.integer(as.hexmode(substr(openssl::md5(x), 1, 1)) %% m)
}

# hash splitting preserves the similarity, because the assignment of test/train 
# is determined by the hash of each obs., and not by its relative location in the data
# which may change 
test1a <- sample1[md5_bit_mod(id) == 0L, .(id)]
test2a <- sample2[md5_bit_mod(id) == 0L, .(id)]
nrow(merge(test1a, test2a))

[1] 5057

nrow(test1a)

sample size is not exactly 5000 because assignment is probabilistic, but it shouldn't be a problem in large samples thanks to the law of large numbers.

I have the same error the result of command :

file hadoop-2.7.2.tar.gz

is hadoop-2.7.2.tar.gz: HTML document, ASCII text

the reason that the file is not gzip format due to problem in download or other.

I got the same error. Tried solutions like cleaning, rebuild, invalidateCache, retart etc but nothing works.

I just have created a new folder with short name and copied all the files(app folder, gradle files etc) in new folder. Opened application in android studio and its working fine.

ID's must be unique (only be given to one element in the DOM at a time), whereas classes don't have to be. You've already discovered the CSS . class and # ID prefixes, so that's pretty much it.

If the ListView is a child of the ListActivity:

getListView().addFooterView(
    getLayoutInflater().inflate(R.layout.footer_view, null)
);

(inside onCreate())

http://handbrake.fr is a nice high level tool with a lot of useful presets for mp4 for iPod, PS3, ... with both GUI and CLI interfaces for Linux, Windows and Mac OS X.

It comes with its own dependencies as a single statically linked fat binary so you have all the x264 / aac codecs included.

  $ HandBrakeCLI -Z Universal -i myinputfile.mov -o myoutputfile.mp4

To list all the available presets:

  $ HandBrakeCLI -z

You can't use a table name for a variable. You'd have to do this instead:

DECLARE @sqlCommand varchar(1000)
SET @sqlCommand = 'SELECT * from yourtable'
EXEC (@sqlCommand)

I have an answer (I admit somewhat confusing answer) that involvessed, regular expressions and capture groups:

• \S* - first word
• \s* - delimiter
• (\S*) - second word - captured
• .* - rest of the line

As a sed expression, the capture group needs to be escaped, i.e. \( and \).

The \1 returns a copy of the captured group, i.e. the second word.

$ echo "alpha beta gamma delta" | sed 's/\S*\s*\(\S*\).*/\1/'
beta

When you look at this answer, its somewhat confusing, and, you may think, why bother? Well, I'm hoping that some, may go "Aha!" and will use this pattern to solve some complex text extraction problems with a single sed expression.

While the OP asks for a CLI command, some of the answers focus on the IDEs. In this answer I just confirm, that the current WebStorm/IntelliJ does allow renaming the component. All that needs to be done is attempting to rename the class in the .ts file. You will be presented with:

and the rename will be performed in all relevant places.

for (let i = 0; i < localStorage.length; i++) {
    if (localStorage.key(i).indexOf('the-name-to-delete') > -1) {
        arr.push(localStorage.key(i));
    }
}

for (let i = 0; i < arr.length; i++) {
    localStorage.removeItem(arr[i]);
}

The accepted answer was correct up until July 2011. To get the latest version, including the Service Pack you should find the latest version as described here:

• http://support.microsoft.com/kb/2527041

For example, if you check the SP2 CTP and SP1, you'll find the latest version of SQL Server Management Studio under SP1:

• http://www.microsoft.com/en-us/download/details.aspx?id=26727

Download the 32-bit (x86) or 64-bit (x64) version of the SQLManagementStudio*.exe files as appropriate and install it. You can find out whether your system is 32-bit or 64-bit by right clicking Computer, selecting Properties and looking at the System Type.

Although you could apply the service pack to the base version that results from following the accepted answer, it's easier to just download the latest version of SQL Server Management Studio and simply install it in one step.

Sounds like it might be a realative uri. I ran into this problem when doing cross-browser Silverlight; on my blog I mentioned a workaround: pass a "context" uri as the first parameter.

If the uri is realtive, the context uri is used to create a full uri. If the uri is absolute, then the context uri is ignored.

EDIT: You need a "scheme" in the uri, e.g., "ftp://" or "http://"

for angular2 with systemjs and jspm had to do:

import * as moment_ from 'moment';
export const moment =  moment_["default"];

var a = moment.now();
var b = moment().format('dddd');
var c = moment().startOf('day').fromNow();

<hostA_shell_prompt>$ ssh user@hostB "ls -la"

That will prompt you for password, unless you have copied your hostA user's public key to the authorized_keys file on the home of user .ssh's directory. That will allow for passwordless authentication (if accepted as an auth method on the ssh server's configuration)

It can be done using a directive. Below is the plunker of the input mask I built.

Note: there are still a few bugs.

Option 1

With Bootstrap 3.2 you can wrap each iframe in the responsive-embed wrapper of your choice:

http://getbootstrap.com/components/#responsive-embed

<!-- 16:9 aspect ratio -->
<div class="embed-responsive embed-responsive-16by9">
  <iframe class="embed-responsive-item" src="…"></iframe>
</div>

<!-- 4:3 aspect ratio -->
<div class="embed-responsive embed-responsive-4by3">
  <iframe class="embed-responsive-item" src="…"></iframe>
</div>

Option 2

If you don't want to wrap your iframes, you can use FluidVids https://github.com/toddmotto/fluidvids. See demo here: http://toddmotto.com/labs/fluidvids/

   <!-- fluidvids.js -->
    <script src="js/fluidvids.js"></script>
    <script>
    fluidvids.init({
      selector: ['iframe'],
      players: ['www.youtube.com', 'player.vimeo.com']
    });
    </script>

The answer by Jones Agyemang is probably sufficient for most use cases and was a great starting point for my solution. For scripting in Git Bent, the git wrapper library I made, I needed something a bit more robust. I'm posting the prototype I've written which is not yet totally script-friendly

Notes

• The linked answer checks for <<<<<<< HEAD which doesn't work for merge conflicts from using git stash apply which has <<<<<<< Updated Upstream
• My solution confirms the presence of ======= & >>>>>>>
• The linked answer is surely more performant, as it doesn't have to do as much
• My solution does NOT provide line numbers

Print files with merge conflicts

You need the str_split_line function from below.

# Root git directory
dir="$(git rev-parse --show-toplevel)"
# Put the grep output into an array (see below)
str_split_line "$(grep -r "^<<<<<<< " "${dir})" files
bn="$(basename "${dir}")"
for i in "${files[@]}"; do 
    # Remove the matched string, so we're left with the file name  
    file="$(sed -e "s/:<<<<<<< .*//" <<< "${i}")"

    # Remove the path, keep the project dir's name  
    fileShort="${file#"${dir}"}"
    fileShort="${bn}${fileShort}"

    # Confirm merge divider & closer are present
    c1=$(grep -c "^=======" "${file}")
    c2=$(grep -c "^>>>>>>> " "${file}")
    if [[ c1 -gt 0 && c2 -gt 0 ]]; then
        echo "${fileShort} has a merge conflict"
    fi
done

Output

projectdir/file-name
projectdir/subdir/file-name

Split strings by line function

You can just copy the block of code if you don't want this as a separate function

function str_split_line(){
# for IFS, see https://stackoverflow.com/questions/16831429/when-setting-ifs-to-split-on-newlines-why-is-it-necessary-to-include-a-backspac
IFS="
"
    declare -n lines=$2
    while read line; do
        lines+=("${line}")
    done <<< "${1}"
}

It means exactly what it says. You're trying to insert a value into a column that has a FK constraint on it that doesn't match any values in the lookup table.

A list is considered to be False if it has no elements, so you can do something like this:

{% if mylist %}
    <p>I have a list!</p>
{% else %}
    <p>I don't have a list!</p>
{% endif %}

I recorded a macro making a hiperlink. This resulted.

ActiveCell.FormulaR1C1 = "=HYPERLINK(""[Workbook.xlsx]Sheet1!A1"",""CLICK HERE"")"

FWIW This may be a bit redundant to all the other answers and is very similar to the accepted answer which is spot on; but maybe it will help someone out.

git stash show --help will give you all you should need; including stash show info.

show [<stash>]

Show the changes recorded in the stash as a diff between the stashed state and its original parent. When no is given, shows the latest one. By default, the command shows the diffstat, but it will accept any format known to git diff (e.g., git stash show -p stash@{1} to view the second most recent stash in patch form). You can use stash.showStat and/or stash.showPatch config variables to change the default behavior.

My problem was took IBOutlet but didn't connect with interface builder and using in swift file.

Delete your bin and obj subfolders to remove a load of incorrect reference then use windows to search for old name.

Edit any code or xml files found and rebuild, should be ok now.

Here is one way to do this using css

HTML

<div class="imageWrapper">
    <img src="http://lorempixel.com/300/300/" alt="" />
    <a href="http://google.com" class="cornerLink">Link</a>
</div>?

CSS

.imageWrapper {
    position: relative;
    width: 300px;
    height: 300px;
}
.imageWrapper img {
    display: block;
}
.imageWrapper .cornerLink {
    opacity: 0;
    position: absolute;
    bottom: 0px;
    left: 0px;
    right: 0px;
    padding: 2px 0px;
    color: #ffffff;
    background: #000000;
    text-decoration: none;
    text-align: center;
    -webkit-transition: opacity 500ms;
    -moz-transition: opacity 500ms;
    -o-transition: opacity 500ms;
    transition: opacity 500ms;

}
.imageWrapper:hover .cornerLink {
    opacity: 0.8;
}

Hint: actively refused sounds like somewhat deeper technical trouble, but...

...actually, this response (and also specifically errno:10061) is also given, if one calls the bin/mongo executable and the mongodb service is simply not running on the target machine. This even applies to local machine instances (all happening on localhost).

? Always rule out for this trivial possibility first, i.e. simply by using the command line client to access your db.

See here.

Your server configuration settings allows users to upload files upto 16MB (because you have set upload_max_filesize = 16Mb) but the post_max_size accepts post data upto 8MB only. This is why it throws an error.

Quoted from the official PHP site:

1. To upload large files, post_max_size value must be larger than upload_max_filesize.

2. memory_limit should be larger than post_max_size

You should always set your post_max_size value greater than the upload_max_filesize value.

in my case i have used both npm install and yarn install that is why i got this issue so to solve this i have removed package-lock.json and node_modules and then i did

yarn install
cd ios
pod install

it worked for me

It is changed to : from PIL.Image import core as image for new versions.

I'm not sure about Tomcat 7, but with Tomcat 6... once you start Tomcat: By going into the bin directory and starting startup.bat (win) or startup.sh (Unix/osx) it will spin up a local instance of the server running usually on port 8080 by default. Then by going to http://localhost:8080/ and seeing that it is running, there is a link to the manager. If that page is not there, you can try loading the manager by going directly to manager/html, and that will load the Host Manager gui.

http://localhost:8080/manager/html

Make sure Tomcat is running first and that 8080 is the right port. These are just the defaults that tomcat usually runs with.

To login you need to edit the conf/tomcat-users.xml, and create a Manager GUI role

<role rolename="manager-gui"/>

and add that to a user

<user username="admin" password="password" roles="manager-gui"/>

Then when you go to Manager GUI app at http://localhost:8080/manager/html it will prompt you for a username/password, which you added to that config file.

To make a simple hexagon without the need for a loop, Just use the beginPath() function. Make sure your canvas.getContext('2d') is the equal to ctx if not it will not work.

I also like to add a variable called times that I can use to scale the object if I need to.This what I don't need to change each number.

     // Times Variable 

     var times = 1;

    // Create a shape

    ctx.beginPath();
    ctx.moveTo(99*times, 0*times);
    ctx.lineTo(99*times, 0*times);
    ctx.lineTo(198*times, 50*times);
    ctx.lineTo(198*times, 148*times);
    ctx.lineTo(99*times, 198*times);
    ctx.lineTo(99*times, 198*times);
    ctx.lineTo(1*times, 148*times);
    ctx.lineTo(1*times,57*times);
    ctx.closePath();
    ctx.clip();
    ctx.stroke();

You need to understand the different between pass-by-reference and pass-by-value.

Basically, C only support pass-by-value. So you can't reference a variable directly when pass it to a function. If you want to change the variable out a function, which the swap do, you need to use pass-by-reference. To implement pass-by-reference in C, need to use pointer, which can dereference to the value.

The function:

void intSwap(int* a, int* b)

It pass two pointers value to intSwap, and in the function, you swap the values which a/b pointed to, but not the pointer itself. That's why R. Martinho & Dan Fego said it swap two integers, not pointers.

For chars, I think you mean string, are more complicate. String in C is implement as a chars array, which referenced by a char*, a pointer, as the string value. And if you want to pass a char* by pass-by-reference, you need to use the ponter of char*, so you get char**.

Maybe the code below more clearly:

typedef char* str;
void strSwap(str* a, str* b);

The syntax swap(int& a, int& b) is C++, which mean pass-by-reference directly. Maybe some C compiler implement too.

Hope I make it more clearly, not comfuse.

First create the file you want, with any editor like vi r gedit. And save with. Py extension.In that the first line should be

!/usr/bin/env python

To reload a section of the page, you could use jquerys load with the current url and specify the fragment you need, which would be the same element that load is called on, in this case #here:

function updateDiv()
{ 
    $( "#here" ).load(window.location.href + " #here" );
}

• Don't disregard the space within the load element selector: + " #here"

This function can be called within an interval, or attached to a click event

This would be better as a comment on bobobobo's answer, but I don't have the rep for that. It accomplishes the same thing but with better practices.

Although the other answers are useful, if you ever need to convert std::string to char* explicitly without const, const_cast is your friend.

std::string str = "string";
char* chr = const_cast<char*>(str.c_str());

Note that this will not give you a copy of the data; it will give you a pointer to the string. Thus, if you modify an element of chr, you'll modify str.

Even though a bit old thread, for those who still looking for the differences:

Aside from layout (space) taken in Hidden and not taken in Collapsed, there is another difference.

If we have custom controls inside this 'Collapsed' main control, the next time we set it to Visible, it will "load" all custom controls. It will not pre-load when window is started.

As for 'Hidden', it will load all custom controls + main control which we set as hidden when the "window" is started.

Seems like you've shadowed the builtin name list pointing at a class by the same name pointing at its instance. Here is an example:

>>> example = list('easyhoss')  # here `list` refers to the builtin class
>>> list = list('abc')  # we create a variable `list` referencing an instance of `list`
>>> example = list('easyhoss')  # here `list` refers to the instance
Traceback (most recent call last):
  File "<string>", line 1, in <module>
TypeError: 'list' object is not callable

I believe this is fairly obvious. Python stores object names (functions and classes are objects, too) in namespaces (which are implemented as dictionaries), hence you can rewrite pretty much any name in any scope. It won't show up as an error of some sort. As you might know, Python emphasizes that "special cases aren't special enough to break the rules". And there are two major rules behind the problem you've faced:

1. Namespaces. Python supports nested namespaces. Theoretically you can endlessly nest namespaces. As I've already mentioned, namespaces are basically dictionaries of names and references to corresponding objects. Any module you create gets its own "global" namespace. In fact it's just a local namespace with respect to that particular module.

2. Scoping. When you reference a name, the Python runtime looks it up in the local namespace (with respect to the reference) and, if such name does not exist, it repeats the attempt in a higher-level namespace. This process continues until there are no higher namespaces left. In that case you get a NameError. Builtin functions and classes reside in a special high-order namespace __builtins__. If you declare a variable named list in your module's global namespace, the interpreter will never search for that name in a higher-level namespace (that is __builtins__). Similarly, suppose you create a variable var inside a function in your module, and another variable var in the module. Then, if you reference var inside the function, you will never get the global var, because there is a var in the local namespace - the interpreter has no need to search it elsewhere.

Here is a simple illustration.

>>> example = list("abc")  # Works fine
>>> 
>>> # Creating name "list" in the global namespace of the module
>>> list = list("abc")
>>> 
>>> example = list("abc")
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'list' object is not callable
>>> # Python looks for "list" and finds it in the global namespace,
>>> # but it's not the proper "list".
>>> 
>>> # Let's remove "list" from the global namespace
>>> del list
>>> # Since there is no "list" in the global namespace of the module,
>>> # Python goes to a higher-level namespace to find the name. 
>>> example = list("abc")  # It works.

So, as you see there is nothing special about Python builtins. And your case is a mere example of universal rules. You'd better use an IDE (e.g. a free version of PyCharm, or Atom with Python plugins) that highlights name shadowing to avoid such errors.

You might as well be wondering what is a "callable", in which case you can read this post. list, being a class, is callable. Calling a class triggers instance construction and initialisation. An instance might as well be callable, but list instances are not. If you are even more puzzled by the distinction between classes and instances, then you might want to read the documentation (quite conveniently, the same page covers namespaces and scoping).

If you want to know more about builtins, please read the answer by Christian Dean.

P.S. When you start an interactive Python session, you create a temporary module.

Of course, you may write a recursive algorithm in Batch that gives you exact control of what you do in every nested subdirectory:

@echo off
set mypath=
call :treeProcess
goto :eof

:treeProcess
setlocal
for %%f in (*.txt) do echo %mypath%%%f
for /D %%d in (*) do (
    set mypath=%mypath%%%d\
    cd %%d
    call :treeProcess
    cd ..
)
endlocal
exit /b

Is there any reason for a class declaration to inherit from object?

In Python 3, apart from compatibility between Python 2 and 3, no reason. In Python 2, many reasons.

Python 2.x story:

In Python 2.x (from 2.2 onwards) there's two styles of classes depending on the presence or absence of object as a base-class:

1. "classic" style classes: they don't have object as a base class:

   >>> class ClassicSpam:      # no base class
   ...     pass
   >>> ClassicSpam.__bases__
   ()
   

2. "new" style classes: they have, directly or indirectly (e.g inherit from a built-in type), object as a base class:

   >>> class NewSpam(object):           # directly inherit from object
   ...    pass
   >>> NewSpam.__bases__
   (<type 'object'>,)
   >>> class IntSpam(int):              # indirectly inherit from object...
   ...    pass
   >>> IntSpam.__bases__
   (<type 'int'>,) 
   >>> IntSpam.__bases__[0].__bases__   # ... because int inherits from object  
   (<type 'object'>,)
   

Without a doubt, when writing a class you'll always want to go for new-style classes. The perks of doing so are numerous, to list some of them:

• Support for descriptors. Specifically, the following constructs are made possible with descriptors:

  1. classmethod: A method that receives the class as an implicit argument instead of the instance.
  2. staticmethod: A method that does not receive the implicit argument self as a first argument.
  3. properties with property: Create functions for managing the getting, setting and deleting of an attribute.
  4. __slots__: Saves memory consumptions of a class and also results in faster attribute access. Of course, it does impose limitations.

• The __new__ static method: lets you customize how new class instances are created.

• Method resolution order (MRO): in what order the base classes of a class will be searched when trying to resolve which method to call.

• Related to MRO, super calls. Also see, super() considered super.

If you don't inherit from object, forget these. A more exhaustive description of the previous bullet points along with other perks of "new" style classes can be found here.

One of the downsides of new-style classes is that the class itself is more memory demanding. Unless you're creating many class objects, though, I doubt this would be an issue and it's a negative sinking in a sea of positives.

Python 3.x story:

In Python 3, things are simplified. Only new-style classes exist (referred to plainly as classes) so, the only difference in adding object is requiring you to type in 8 more characters. This:

class ClassicSpam:
    pass

is completely equivalent (apart from their name :-) to this:

class NewSpam(object):
     pass

and to this:

class Spam():
    pass

All have object in their __bases__.

>>> [object in cls.__bases__ for cls in {Spam, NewSpam, ClassicSpam}]
[True, True, True]

So, what should you do?

In Python 2: always inherit from object explicitly. Get the perks.

In Python 3: inherit from object if you are writing code that tries to be Python agnostic, that is, it needs to work both in Python 2 and in Python 3. Otherwise don't, it really makes no difference since Python inserts it for you behind the scenes.

The Gradle build system for Android supports "resource shrinking": the automatic removal of resources that are unused, at build time, in the packaged app. In addition to removing resources in your project that are not actually needed at runtime, this also removes resources from libraries you are depending on if they are not actually needed by your application.

To enable this add the line shrinkResources true in your gradle file.

   android {
        ...

        buildTypes {
            release {
                minifyEnabled true //Important step
                shrinkResources true
            }
   }
}

This question is the top Google result for "Java String Right".

Surprisingly, no-one has yet mentioned Apache Commons StringUtils.right():

String numbers = org.apache.commons.lang.StringUtils.right( text, 7 );

This also handles the case where text is null, where many of the other answers would throw a NullPointerException.

In addition to options suggested by others I can recommend the fmt library which implements string formatting similar to str.format in Python and String.Format in C#. Here's an example:

std::string a = "test";
std::string b = "text.txt";
std::string c = "text1.txt";
std::string result = fmt::format("{0} {1} > {2}", a, b, c);

video/mp4should be used when you have video content in your file. If there is none, but there is audio, you should use audio/mp4. If no audio and no video is used, for instance if the file contains only a subtitle track or a metadata track, the MIME should be application/mp4. Also, as a server, you should try to include the codecs or profiles parameters as defined in RFC6381, as this will help clients determine if they can play the file, prior to downloading it.

Ruby 2.7+

There is now!

Ruby 2.7 is introducing filter_map for this exact purpose. It's idiomatic and performant, and I'd expect it to become the norm very soon.

For example:

numbers = [1, 2, 5, 8, 10, 13]
enum.filter_map { |i| i * 2 if i.even? }
# => [4, 16, 20]

In your case, as the block evaluates to falsey, simply:

items.filter_map { |x| process_x url }

"Ruby 2.7 adds Enumerable#filter_map" is a good read on the subject, with some performance benchmarks against some of the earlier approaches to this problem:

N = 100_000
enum = 1.upto(1_000)
Benchmark.bmbm do |x|
  x.report("select + map")  { N.times { enum.select { |i| i.even? }.map{ |i| i + 1 } } }
  x.report("map + compact") { N.times { enum.map { |i| i + 1 if i.even? }.compact } }
  x.report("filter_map")    { N.times { enum.filter_map { |i| i + 1 if i.even? } } }
end

If you look up the help page, one of the arguments to lapply is the mysterious .... When we look at the Arguments section of the help page, we find the following line:

...: optional arguments to ‘FUN’.

So all you have to do is include your other argument in the lapply call as an argument, like so:

lapply(input, myfun, arg1=6)

and lapply, recognizing that arg1 is not an argument it knows what to do with, will automatically pass it on to myfun. All the other apply functions can do the same thing.

An addendum: You can use ... when you're writing your own functions, too. For example, say you write a function that calls plot at some point, and you want to be able to change the plot parameters from your function call. You could include each parameter as an argument in your function, but that's annoying. Instead you can use ... (as an argument to both your function and the call to plot within it), and have any argument that your function doesn't recognize be automatically passed on to plot.

There are two major performance issues with your code:

• Using Add method
• Using SaveChanges

Using Add method

The Add method becomes only slower and slower at each entity you add.

See: http://entityframework.net/improve-ef-add-performance

For example, adding 10,000 entities via:

• Add (take ~105,000ms)
• AddRange (take ~120ms)

Note: Entities has not been saved yet in the database!

The problem is that the Add method tries to DetectChanges at every entity added while AddRange does it once after all entities have been added to the context.

Common solutions are:

• Use AddRange over Add
• SET AutoDetectChanges to false
• SPLIT SaveChanges in multiple batches

Using SaveChanges

Entity Framework has not been created for Bulk Operations. For every entity you save, a database round-trip is performed.

So, if you want to insert 20,000 records, you will perform 20,000 database round-trip which is INSANE!

There are some third-party libraries supporting Bulk Insert available:

• Z.EntityFramework.Extensions (Recommended)
• EFUtilities
• EntityFramework.BulkInsert

See: Entity Framework Bulk Insert library

Be careful, when choosing a bulk insert library. Only Entity Framework Extensions support all kind of associations and inheritance, and it's the only one still supported.

Disclaimer: I'm the owner of Entity Framework Extensions

This library allows you to perform all bulk operations you need for your scenarios:

• Bulk SaveChanges
• Bulk Insert
• Bulk Delete
• Bulk Update
• Bulk Merge

Example

// Easy to use
context.BulkSaveChanges();

// Easy to customize
context.BulkSaveChanges(bulk => bulk.BatchSize = 100);

// Perform Bulk Operations
context.BulkDelete(customers);
context.BulkInsert(customers);
context.BulkUpdate(customers);

// Customize Primary Key
context.BulkMerge(customers, operation => {
   operation.ColumnPrimaryKeyExpression = 
        customer => customer.Code;
});

EDIT: Answer Question in Comment

Is there a recommend max size for each bulk insert for the library you created

Not too high, not too low. There isn't a particular value that fit in all scenarios since it depends on multiple factors such as row size, index, trigger, etc.

It's normally recommended to be around 4000.

Also is there a way to tie it all in one transaction and not worry about it timing out

You can use Entity Framework transaction. Our library uses the transaction if one is started. But be careful, a transaction that takes too much time come also with problems such as some row/index/table lock.

Look at the filter function.

If you just need a 1-pole low-pass filter, it's

xfilt = filter(a, [1 a-1], x);

where a = T/τ, T = the time between samples, and τ (tau) is the filter time constant.

Here's the corresponding high-pass filter:

xfilt = filter([1-a a-1],[1 a-1], x);

If you need to design a filter, and have a license for the Signal Processing Toolbox, there's a bunch of functions, look at fvtool and fdatool.

If you want to compile and run Java/C/C++ apps directly on your Android device, I recommend the Terminal IDE environment from Google Play. It's a very slick package to develop and compile Android APKs, Java, C and C++ directly on your device. The interface is all command line and "vi" based, so it has real Linux feel. It comes with the gnu C/C++ implementation.

Additionally, there is a telnet and telnet server application built in, so you can do all the programming with your PC and big keyboard, but working on the device. No root permission is needed.

My Source: http://htmlhelp.com/tools/validator/problems.html#amp

Another common error occurs when including a URL which contains an ampersand ("&"):

This is invalid:

a href="foo.cgi?chapter=1&section=2&copy=3&lang=en"

Explanation:

This example generates an error for "unknown entity section" because the "&" is assumed to begin an entity reference. Browsers often recover safely from this kind of error, but real problems do occur in some cases. In this example, many browsers correctly convert &copy=3 to ©=3, which may cause the link to fail. Since ⟨ is the HTML entity for the left-pointing angle bracket, some browsers also convert &lang=en to <=en. And one old browser even finds the entity §, converting &section=2 to §ion=2.

So the goal here is to avoid problems when you are trying to validate your website. So you should be replacing your ampersands with & when writing a URL in your markup.

Note that replacing & with &amp; is only done when writing the URL in HTML, where "&" is a special character (along with "<" and ">"). When writing the same URL in a plain text email message or in the location bar of your browser, you would use "&" and not "&". With HTML, the browser translates "&" to "&" so the Web server would only see "&" and not "&" in the query string of the request.

Hope this helps : )

Use UUID function.

I don't know the source of your procedures in PHP that generates unique values. If it is library function they should guarantee that your value is really unique. Check in documentation. You should, hovewer, use this function all the time. If you, for example, use PHP function to generate unique value, and then you decide to use MySQL function, you can generate value that already exist. In this case putting UNIQUE INDEX on the column is also a good idea.

You say you have a database on PhpMyAdmin, so you are using MySQL. PHP provides functions for connecting to a MySQL database.

$connection = mysql_connect('localhost', 'root', ''); //The Blank string is the password
mysql_select_db('hrmwaitrose');

$query = "SELECT * FROM employee"; //You don't need a ; like you do in SQL
$result = mysql_query($query);

echo "<table>"; // start a table tag in the HTML

while($row = mysql_fetch_array($result)){   //Creates a loop to loop through results
echo "<tr><td>" . $row['name'] . "</td><td>" . $row['age'] . "</td></tr>";  //$row['index'] the index here is a field name
}

echo "</table>"; //Close the table in HTML

mysql_close(); //Make sure to close out the database connection

In the while loop (which runs every time we encounter a result row), we echo which creates a new table row. I also add a to contain the fields.

This is a very basic template. You see the other answers using mysqli_connect instead of mysql_connect. mysqli stands for mysql improved. It offers a better range of features. You notice it is also a little bit more complex. It depends on what you need.

So interestingly enough this error "Transport endpoint is not connected" was caused by my having more than one Veracrypt device mounted. I closed the extra device and suddenly I had access to the drive. Hmm..

Combination of all of these suggestions, and the reasons behind them. Feel free to add more test cases too. If getting the client IP is of utmost importance, than you might wan to get all of theses are run some comparisons on which result might be more accurate.

Simple check of all suggestions in this thread plus some of my own code...

    using System.IO;
    using System.Net;

    public string GetUserIP()
    {
        string strIP = String.Empty;
        HttpRequest httpReq = HttpContext.Current.Request;

        //test for non-standard proxy server designations of client's IP
        if (httpReq.ServerVariables["HTTP_CLIENT_IP"] != null)
        {
            strIP = httpReq.ServerVariables["HTTP_CLIENT_IP"].ToString();
        }
        else if (httpReq.ServerVariables["HTTP_X_FORWARDED_FOR"] != null)
        {
            strIP = httpReq.ServerVariables["HTTP_X_FORWARDED_FOR"].ToString();
        }
        //test for host address reported by the server
        else if
        (
            //if exists
            (httpReq.UserHostAddress.Length != 0)
            &&
            //and if not localhost IPV6 or localhost name
            ((httpReq.UserHostAddress != "::1") || (httpReq.UserHostAddress != "localhost"))
        )
        {
            strIP = httpReq.UserHostAddress;
        }
        //finally, if all else fails, get the IP from a web scrape of another server
        else
        {
            WebRequest request = WebRequest.Create("http://checkip.dyndns.org/");
            using (WebResponse response = request.GetResponse())
            using (StreamReader sr = new StreamReader(response.GetResponseStream()))
            {
                strIP = sr.ReadToEnd();
            }
            //scrape ip from the html
            int i1 = strIP.IndexOf("Address: ") + 9;
            int i2 = strIP.LastIndexOf("</body>");
            strIP = strIP.Substring(i1, i2 - i1);
        }
        return strIP;
    }

If you ran into this issue when using TypeScript, you may need to add skipLibCheck: true in your tsconfig.json file.

From the docs page, notice they have these helpful headers

http://momentjs.com/docs/#/get-set/weekday/
(I didn't see them at first)

With header sections for:

• Date of Month
• Day of Week
• etc

.

  var now = moment();
  var day  = now.day();
  var date = now.date(); // Number

Another useful (Python-based) tool for this is Androguard, using its axml sub-command:

androguard axml my.apk -o my.xml

This extracts and decodes the app manifest in one go. Unlike apktool this doesn't unpack anything else.

Very simple way in codeigniter to call a method of one controller to other controller

1. Controller A 
   class A extends CI_Controller {

    public function __construct()
    {
        parent::__construct();
    }
    function custom_a()
    {
    }
}

2. Controller B 

   class B extends CI_Controller {

    public function __construct()
    {
        parent::__construct();
    }
    function custom_b()
    {
            require_once(APPPATH.'controllers/a.php'); //include controller
            $aObj = new a();  //create object 
            $aObj->custom_a(); //call function
    }
}

When I used the solution stated by Dason, instead of getting a data frame as a result, I got a vector of numbers (the scaled values of my df).

In case someone is having the same trouble, you have to add as.data.frame() to the code, like this:

df.scaled <- as.data.frame(scale(df))

I hope this is will be useful for ppl having the same issue!

I had no snap files. Going through the help menu installation list, at least 90% of my plugins had the uninstall button deactivated so I could not handle it through there. Under startup/shutdown most of plugins were not listed. Instead, I had to manually remove items from my plugins folder. Wow, the startup time is much faster for me now. So if everything else does not work and you have plugins that are disposable, this could be the ultimate solution to use.

Use strncpy

e.g.

strncpy(dest, src + beginIndex, endIndex - beginIndex);

This assumes you've

1. Validated that dest is large enough.
2. endIndex is greater than beginIndex
3. beginIndex is less than strlen(src)
4. endIndex is less than strlen(src)

At the time of writing in 2013, this was one way to do it. Composer has added support for better ways: See @igorw 's answer

DO YOU HAVE A REPOSITORY?

Git, Mercurial and SVN is supported by Composer.

DO YOU HAVE WRITE ACCESS TO THE REPOSITORY?

Yes?

DOES THE REPOSITORY HAVE A composer.json FILE

If you have a repository you can write to: Add a composer.json file, or fix the existing one, and DON'T use the solution below.

Go to @igorw 's answer

ONLY USE THIS IF YOU DON'T HAVE A REPOSITORY
OR IF THE REPOSITORY DOES NOT HAVE A composer.json AND YOU CANNOT ADD IT

This will override everything that Composer may be able to read from the original repository's composer.json, including the dependencies of the package and the autoloading.

Using the package type will transfer the burden of correctly defining everything onto you. The easier way is to have a composer.json file in the repository, and just use it.

This solution really only is for the rare cases where you have an abandoned ZIP download that you cannot alter, or a repository you can only read, but it isn't maintained anymore.

To make it work in JSON, you need to escape a few more character than that.

myString.replace("\\", "\\\\")
    .replace("\"", "\\\"")
    .replace("\r", "\\r")
    .replace("\n", "\\n")

and if you want to be able to use json2.js to parse it then you also need to escape

   .replace("\u2028", "\\u2028")
   .replace("\u2029", "\\u2029")

which JSON allows inside quoted strings, but which JavaScript does not.

Simply you can use padding-top and padding-bottom on a td element.

Unit can anything from this list:

Demo Code:

td_x000D_
{_x000D_
  padding-top: 10px;_x000D_
  padding-bottom: 10px;_x000D_
}

<table>_x000D_
  <tr>_x000D_
    <th>Firstname</th>_x000D_
    <th>Lastname</th>_x000D_
  </tr>_x000D_
  <tr>_x000D_
    <td>Peter</td>_x000D_
    <td>Griffin</td>_x000D_
  </tr>_x000D_
  <tr>_x000D_
    <td>Lois</td>_x000D_
    <td>Griffin</td>_x000D_
  </tr>_x000D_
</table>

You don't need --header "Content-Length: $LENGTH".

curl --request POST --data-binary "@template_entry.xml" $URL

Note that GET request does not support content body widely.

Also remember that POST request have 2 different coding schema. This is first form:

  $ nc -l -p 6666 &
  $ curl  --request POST --data-binary "@README" http://localhost:6666

POST / HTTP/1.1
User-Agent: curl/7.21.0 (x86_64-pc-linux-gnu) libcurl/7.21.0 OpenSSL/0.9.8o zlib/1.2.3.4 libidn/1.15 libssh2/1.2.6

.. -*- mode: rst; coding: cp1251; fill-column: 80 -*-

.. contents::

You probably request this:

-F/--form name=content
           (HTTP) This lets curl emulate a filled-in form in
              which a user has pressed the submit button. This
              causes curl to POST data using the Content- Type
              multipart/form-data according to RFC2388. This
              enables uploading of binary files etc. To force the
              'content' part to be a file, prefix the file name
              with an @ sign. To just get the content part from a
              file, prefix the file name with the symbol <. The
              difference between @ and < is then that @ makes a
              file get attached in the post as a file upload,
              while the < makes a text field and just get the
              contents for that text field from a file.

I can understand your pain. In my case the error got resolved by performing below steps:

1. Start > Run > dcomcnfg.
2. Open the folder DCOM Config and Select Component Services > Computers > My Computer > DCOM Config.
3. Select “Microsoft Office Word 97 – 2003 document”/”Microsoft Excel Application” and go to its properties.
4. In "Security" tab set “Launch and Activation Permissions” need to be Customize (Authorized user).
5. Now go to IIS and select application pool of the Web and go to its Advanced Settings and select “NETWORK SERVICE” as identity user.

Hope this helps.

Red Alert pointed out that the code uses memcpy from array to array and std::copy from array to vector. That coud be a reason for faster memcpy.

Since there is

v.reserve(sizeof(arr1));

there shall be no difference in copy to vector or array.

The code is fixed to use array for both cases. memcpy still faster:

{
    time_t t = time(NULL);
    for(uint32_t i = 0; i < iterations; ++i)
        memcpy(arr1, arr2, sizeof(arr1));
    printf("memcpy()    elapsed %ld s\n", time(NULL) - t);
}

{
    time_t t = time(NULL);
    for(uint32_t i = 0; i < iterations; ++i)
        std::copy(arr1, arr1 + sizeof(arr1), arr2);
    printf("std::copy() elapsed %ld s\n", time(NULL) - t);
}

memcpy()    elapsed 44 s

I got the same error when using policy as below, although i have "s3:ListBucket" for s3:ListObjects operation.

Using regular ng-view module you cannot have more than one dynamic template.

However, this project enables you to do so (look for ui-router).

For Leaflet, I'm using

    map.setView(markersLayer.getBounds().getCenter());

Same problem here, this worked just fine:

$('input[name="someRadioGroup"]').change(function() {
    $('#r1edit:input').prop('disabled', !$("#r1").is(':checked'));
});

I've faced the same issue and want to share how I solved it and why.

As you mentioned there are two problems. The first:

In Asp.Net Core how do I register these services and resolve it at runtime based on some key?

So what options do we have? Folks suggest two:

• Use a custom factory (like _myFactory.GetServiceByKey(key))

• Use another DI engine (like _unityContainer.Resolve<IService>(key))

Is the Factory pattern the only option here?

In fact both options are factories because each IoC Container is also a factory (highly configurable and complicated though). And it seems to me that other options are also variations of the Factory pattern.

So what option is better then? Here I agree with @Sock who suggested using custom factory, and that is why.

First, I always try to avoid adding new dependencies when they are not really needed. So I agree with you in this point. Moreover, using two DI frameworks is worse than creating custom factory abstraction. In the second case you have to add new package dependency (like Unity) but depending on a new factory interface is less evil here. The main idea of ASP.NET Core DI, I believe, is simplicity. It maintains a minimal set of features following KISS principle. If you need some extra feature then DIY or use a corresponding Plungin that implements desired feature (Open Closed Principle).

Secondly, often we need to inject many named dependencies for single service. In case of Unity you may have to specify names for constructor parameters (using InjectionConstructor). This registration uses reflection and some smart logic to guess arguments for the constructor. This also may lead to runtime errors if registration does not match the constructor arguments. From the other hand, when using your own factory you have full control of how to provide the constructor parameters. It's more readable and it's resolved at compile-time. KISS principle again.

The second problem:

How can _serviceProvider.GetService() inject appropriate connection string?

First, I agree with you that depending on new things like IOptions (and therefore on package Microsoft.Extensions.Options.ConfigurationExtensions) is not a good idea. I've seen some discussing about IOptions where there were different opinions about its benifit. Again, I try to avoid adding new dependencies when they are not really needed. Is it really needed? I think no. Otherwise each implementation would have to depend on it without any clear need coming from that implementation (for me it looks like violation of ISP, where I agree with you too). This is also true about depending on the factory but in this case it can be avoided.

The ASP.NET Core DI provides a very nice overload for that purpose:

var mongoConnection = //...
var efConnection = //...
var otherConnection = //...
services.AddTransient<IMyFactory>(
             s => new MyFactoryImpl(
                 mongoConnection, efConnection, otherConnection, 
                 s.GetService<ISomeDependency1>(), s.GetService<ISomeDependency2>())));

These words existed way before Computer Science came around.

1. Attribute is a quality or object that we attribute to someone or something. For example, the scepter is an attribute of power and statehood.

2. Property is a quality that exists without any attribution. For example, clay has adhesive qualities; i.e, a property of clay is its adhesive quality. Another example: one of the properties of metals is electrical conductivity. Properties demonstrate themselves through physical phenomena without the need to attribute them to someone or something. By the same token, saying that someone has masculine attributes is self-evident. In effect, you could say that a property is owned by someone or something.

To be fair though, in Computer Science these two words, at least for the most part, can be used interchangeably - but then again programmers usually don't hold degrees in English Literature and do not write or care much about grammar books :).

You need to use backtick instead of single quotes:

Single quote - 'Business Name' - Wrong

Backtick - `Business Name` - Correct

You can try this

string s1 = "Hello";
string s2 = "el";
if(strstr(s1.c_str(),s2.c_str()))
{
   cout << " S1 Contains S2";
}

For me, once there was a mistake in spelling of function

For e.g. instead of

$(document).ready(function(){

});

I wrote

$(document).ready(funciton(){

});

So keep that also in check

One way, making the preprocessor do the work. It also ensures your enums and strings are in sync.

#define FOREACH_FRUIT(FRUIT) \
        FRUIT(apple)   \
        FRUIT(orange)  \
        FRUIT(grape)   \
        FRUIT(banana)  \

#define GENERATE_ENUM(ENUM) ENUM,
#define GENERATE_STRING(STRING) #STRING,

enum FRUIT_ENUM {
    FOREACH_FRUIT(GENERATE_ENUM)
};

static const char *FRUIT_STRING[] = {
    FOREACH_FRUIT(GENERATE_STRING)
};

After the preprocessor gets done, you'll have:

enum FRUIT_ENUM {
    apple, orange, grape, banana,
};

static const char *FRUIT_STRING[] = {
    "apple", "orange", "grape", "banana",
};

Then you could do something like:

printf("enum apple as a string: %s\n",FRUIT_STRING[apple]);

If the use case is literally just printing the enum name, add the following macros:

#define str(x) #x
#define xstr(x) str(x)

Then do:

printf("enum apple as a string: %s\n", xstr(apple));

In this case, it may seem like the two-level macro is superfluous, however, due to how stringification works in C, it is necessary in some cases. For example, let's say we want to use a #define with an enum:

#define foo apple

int main() {
    printf("%s\n", str(foo));
    printf("%s\n", xstr(foo));
}

The output would be:

foo
apple

This is because str will stringify the input foo rather than expand it to be apple. By using xstr the macro expansion is done first, then that result is stringified.

See Stringification for more information.

When I have added/modified/deleted many files (since the last commit), I like to look at those modifications in chronological order.

For that I use:

• To list all non-staged files:

  git ls-files --other --modified --exclude-standard
  

• To get the last modified date for each file:

  while read filename; do  echo -n "$(stat -c%y -- $filename 2> /dev/null) "; echo $filename;  done
  

Although ruvim suggests in the comments:

xargs -0 stat -c '%y %n' -- 

• To sort them from oldest to more recent:

  sort
  

An alias makes it easier to use:

alias gstlast='git ls-files --other --modified --exclude-standard|while read filename; do  echo -n "$(stat -c%y -- $filename 2> /dev/null) "; echo $filename;  done|sort'

Or (shorter and more efficient, thanks to ruvim)

alias gstlast='git ls-files --other --modified --exclude-standard|xargs -0 stat -c '%y %n' --|sort'

For example:

username@hostname:~> gstlast
2015-01-20 11:40:05.000000000 +0000 .cpl/params/libelf
2015-01-21 09:02:58.435823000 +0000 .cpl/params/glib

I now can review my modifications, from oldest to more recent.

"Lean and Mean" TIMER with Regional format, 24h and mixed input support
Adapting Aacini's substitution method body, no IF's, just one FOR (my regional fix)

1: File timer.bat placed somewhere in %PATH% or the current dir

@echo off & rem :AveYo: compact timer function with Regional format, 24-hours and mixed input support

endlocal & set "timer_end=%value%" & set "timer_set=" & goto :eof

Usage:
timer & echo start_cmds & timeout /t 3 & echo end_cmds & timer
timer & timer "23:23:23,00"
timer "23:23:23,00" & timer
timer "13.23.23,00" & timer "03:03:03.00"
timer & timer "0:00:00.00" no & cmd /v:on /c echo until midnight=!timer_end!
Input can now be mixed, for those unlikely, but possible time format changes during execution

2: Function :timer bundled with the batch script (sample usage below):

@echo off
set "TIMER=call :timer" & rem short macro
echo.
echo EXAMPLE:
call :timer
timeout /t 3 >nul & rem Any process here..
call :timer
echo.
echo SHORT MACRO:
%TIMER% & timeout /t 1 & %TIMER% 
echo.
echo TEST INPUT:
set "start=22:04:04.58"
set "end=04.22.44,22"
echo %start% ~ start & echo %end% ~ end
call :timer "%start%"
call :timer "%end%"
echo.
%TIMER% & %TIMER% "00:00:00.00" no 
echo UNTIL MIDNIGHT: %timer_end%
echo.
pause 
exit /b

:: to test it, copy-paste both above and below code sections

If you want to create a garage and fill it up with new cars that can be accessed later, use this code:

for (int i = 0; i < garage.length; i++)
     garage[i] = new Car("argument");

Also, the cars are later accessed using:

garage[0];
garage[1];
garage[2];
etc.

I was able to solve the issue by following these steps-

1.) This error occurs when you didn't connect your project to firebase. Do that from Tools->Firebase if you are using Android studio version 2.2 or above.

2.) Make sure you have replaced the compile with implementation in dependencies in app/build.gradle

3.) Include your firebase dependency from the firebase docs. Everything should work fine now

If you are trying to get multiple mobile numbers in the same text (re.findall) then you should probably use the following. It's basically on the same lines as the ones that are already mentioned but it also has special look behind and look ahead assertions so that we don't pick a mobile number immediately preceded or immediately followed by a digit. I've also added 0? just before capturing the actual mobile number to handle special cases where people prepend 0 to the mobile number.

(?<!\d)(?:\+91|91)?\W*(?P<mobile>[789]\d{9})(?!\d)

You may try it on pythex.org!

A more permanent solution is to subclass float:

>>> class prettyfloat(float):
    def __repr__(self):
        return "%0.2f" % self

>>> x
[1.290192, 3.0002, 22.119199999999999, 3.4110999999999998]
>>> x = map(prettyfloat, x)
>>> x
[1.29, 3.00, 22.12, 3.41]
>>> y = x[2]
>>> y
22.12

The problem with subclassing float is that it breaks code that's explicitly looking for a variable's type. But so far as I can tell, that's the only problem with it. And a simple x = map(float, x) undoes the conversion to prettyfloat.

Tragically, you can't just monkey-patch float.__repr__, because float's immutable.

If you don't want to subclass float, but don't mind defining a function, map(f, x) is a lot more concise than [f(n) for n in x]

Again with getElementById, but instead .value, use .innerText

<td id="test">Chicken</td>
document.getElementById('test').innerText; //the value of this will be 'Chicken'

What the PHP Notice means and how to reproduce it:

If you send a PHP array into a function that expects a string like: echo or print, then the PHP interpreter will convert your array to the literal string Array, throw this Notice and keep going. For example:

php> print(array(1,2,3))

PHP Notice:  Array to string conversion in 
/usr/local/lib/python2.7/dist-packages/phpsh/phpsh.php(591) :
eval()'d code on line 1
Array

In this case, the function print dumps the literal string: Array to stdout and then logs the Notice to stderr and keeps going.

Another example in a PHP script:

<?php
    $stuff = array(1,2,3);
    print $stuff;  //PHP Notice:  Array to string conversion in yourfile on line 3
?>

Correction 1: use foreach loop to access array elements

http://php.net/foreach

$stuff = array(1,2,3);
foreach ($stuff as $value) {
    echo $value, "\n";
}

Prints:

1
2
3

Or along with array keys

$stuff = array('name' => 'Joe', 'email' => '[email protected]');
foreach ($stuff as $key => $value) {
    echo "$key: $value\n";
}

Prints:

name: Joe
email: [email protected]

Note that array elements could be arrays as well. In this case either use foreach again or access this inner array elements using array syntax, e.g. $row['name']

Correction 2: Joining all the cells in the array together:

In case it's just a plain 1-demensional array, you can simply join all the cells into a string using a delimiter:

<?php
    $stuff = array(1,2,3);
    print implode(", ", $stuff);    //prints 1, 2, 3
    print join(',', $stuff);        //prints 1,2,3

Correction 3: Stringify an array with complex structure:

In case your array has a complex structure but you need to convert it to a string anyway, then use http://php.net/json_encode

$stuff = array('name' => 'Joe', 'email' => '[email protected]');
print json_encode($stuff);

Prints

{"name":"Joe","email":"[email protected]"}

A quick peek into array structure: use the builtin php functions

If you want just to inspect the array contents for the debugging purpose, use one of the following functions. Keep in mind that var_dump is most informative of them and thus usually being preferred for the purpose

• http://php.net/print_r
• http://php.net/var_dump
• http://php.net/var_export

examples

$stuff = array(1,2,3);
print_r($stuff);
$stuff = array(3,4,5);
var_dump($stuff);

Prints:

Array
(
    [0] => 1
    [1] => 2
    [2] => 3
)
array(3) {
  [0]=>
  int(3)
  [1]=>
  int(4)
  [2]=>
  int(5)
}

In insert()

public void insert(String tableImg, Object object,
        ContentValues dataToInsert) {

   db.insert(tablename, null, dataToInsert);
}

Hope it helps you.

You could create a DataView object from your datasource. This would allow you to filter and sort your data without directly modifying the datasource.

Also, remember to call dataGridView1.DataBind(); after you set the data source.

// To delete all the folders and files within folders recursively
File sdDir = new File(sdPath);

if(sdDir.exists())
    deleteRecursive(sdDir);




// Delete any folder on a device if exists
void deleteRecursive(File fileOrDirectory) {
    if (fileOrDirectory.isDirectory())
    for (File child : fileOrDirectory.listFiles())
        deleteRecursive(child);

    fileOrDirectory.delete();
}

On my clean macOS 10.15.7, I needed to brew link gnupg && brew unlink gnupg first and then used Ashish's answer to use gpg instead of gpg2. I also had to chown a few directories. before the un/link.

There are a few solutions; if you are comfortable with CSS, here's a very flexible solution:

Create an appropriately styled Panel that resembles a "Message Box", put a Label in it and set its Visible property to false. Then whenever the user needs to see a message after a postback (e.g. pushing a button), from codebehind set the Labels Text property to the desired error message and set the Panel's Visible property to true.

General sibling combinator

The general sibling combinator selector is very similar to the adjacent sibling combinator selector. The difference is that the element being selected doesn't need to immediately succeed the first element, but can appear anywhere after it.

just surround your text with < u > tag in your string.xml resource file

<string name="your_string"><u>Underlined text</u></string>

and in your Activity/Fragment

mTextView.setText(R.string.your_string);

A simple answer would be : No, it doesn't

Explanation : According to the definition of unique constraints (SQL-92)

A unique constraint is satisfied if and only if no two rows in a table have the same non-null values in the unique columns

This statement can have two interpretations as :

• No two rows can have same values i.e. NULL and NULL is not allowed
• No two non-null rows can have values i.e NULL and NULL is fine, but StackOverflow and StackOverflow is not allowed

Since MySQL follows second interpretation, multiple NULL values are allowed in UNIQUE constraint column. Second, if you would try to understand the concept of NULL in SQL, you will find that two NULL values can be compared at all since NULL in SQL refers to unavailable or unassigned value (you can't compare nothing with nothing). Now, if you are not allowing multiple NULL values in UNIQUE constraint column, you are contracting the meaning of NULL in SQL. I would summarise my answer by saying :

MySQL supports UNIQUE constraint but not on the cost of ignoring NULL values

Put the frame in a VisualBrush:

VisualBrush brush = new VisualBrush { TileMode = TileMode.None };

brush.Visual = frame;

brush.AlignmentX = AlignmentX.Center;
brush.AlignmentY = AlignmentY.Center;
brush.Stretch = Stretch.Uniform;

Put the VisualBrush in GeometryDrawing

GeometryDrawing drawing = new GeometryDrawing();

drawing.Brush = brush;

// Brush this in 1, 1 ratio
RectangleGeometry rect = new RectangleGeometry { Rect = new Rect(0, 0, 1, 1) };
drawing.Geometry = rect;

Now put the GeometryDrawing in a DrawingImage:

new DrawingImage(drawing);

Place this on your source of the image, and voilà!

You could do it a lot easier though:

<Image>
    <Image.Source>
        <BitmapImage UriSource="/yourassembly;component/YourImage.PNG"></BitmapImage>
    </Image.Source>
</Image>

And in code:

BitmapImage image = new BitmapImage { UriSource="/yourassembly;component/YourImage.PNG" };

The usual API for this is DirectShow.

You can use P/Invoke to import the C++ APIs, but I think there are already a few projects out there that have done this.

http://channel9.msdn.com/forums/TechOff/93476-Programatically-Using-A-Webcam-In-C/

http://www.codeproject.com/KB/directx/DirXVidStrm.aspx

To get the streaming part, you probably want to use DirectShow to apply a compression codec to reduce lag, then you can get a Stream and transmit it. You could consider using multicast to reduce network load.

JSON.stringify

JSON.stringify(`{ 
  a:"a"
}`)

would convert the above string to

"{ \n      a:\"a\"\n    }"

as mentioned here

json stringify

This function adds double quotes at the beginning and end of the input string and escapes special JSON characters. In particular, a newline is replaced by the \n character, a tab is replaced by the \t character, a backslash is replaced by two backslashes \, and a backslash is placed before each quotation mark.

You can create any kind of your own assertions based on assertions from junit:

static void assertDoesNotThrow(Executable executable) {
    assertDoesNotThrow(executable, "must not throw");
}
static void assertDoesNotThrow(Executable executable, String message) {
    try {
        executable.execute();
    } catch (Throwable err) {
        fail(message);
    }
}

And test:

//the following will succeed
assertDoesNotThrow(()->methodMustNotThrow(1));
assertDoesNotThrow(()->methodMustNotThrow(1), "fail with specific message: facepalm");
//the following will fail
assertDoesNotThrow(()->methodMustNotThrow(2));
assertDoesNotThrow(()-> {throw new Exception("Hello world");}, "Fail: must not trow");

Generally speaking there is possibility to instantly fail("bla bla bla") the test in any scenarios, in any place where it makes sense. For instance use it in a try/catch block to fail if anything is thrown in the test case:

try{methodMustNotThrow(1);}catch(Throwable e){fail("must not throw");}
//or
try{methodMustNotThrow(1);}catch(Throwable e){Assertions.fail("must not throw");}

This is the sample of the method we test, supposing we have such a method that must not fail under specific circumstances, but it can fail:

void methodMustNotThrow(int x) throws Exception{
    if (x == 1) return;
    throw new Exception();
}

The above method is a simple sample. But this works for complex situations, where the failure is not so obvious. There are the imports:

import org.junit.jupiter.api.Assertions;
import org.junit.jupiter.api.Test;
import org.junit.jupiter.api.function.Executable;
import static org.junit.jupiter.api.Assertions.*;

You can also use sum, if you give it a start argument:

>>> list1, list2, list3 = [1,2,3], ['a','b','c'], [7,8,9]
>>> all_lists = sum([list1, list2, list3], [])
>>> all_lists
[1, 2, 3, 'a', 'b', 'c', 7, 8, 9]

This works in general for anything that has the + operator:

>>> sum([(1,2), (1,), ()], ())
(1, 2, 1)

>>> sum([Counter('123'), Counter('234'), Counter('345')], Counter())
Counter({'1':1, '2':2, '3':3, '4':2, '5':1})

>>> sum([True, True, False], False)
2

With the notable exception of strings:

>>> sum(['123', '345', '567'], '')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: sum() can't sum strings [use ''.join(seq) instead]

response[0] is not defined, check if it is defined and then check for its property title.

if(typeof response[0] !== 'undefined' && typeof response[0].title !== 'undefined'){
    //Do something
}

Have a look at the MDN article about window.location.

The QueryString is available in window.location.search.

Solution that work in legacy browsers as well

MDN provide an example (no longer available in the above referenced article) of how to the get value of a single key available in the QueryString. Something like this:

function getQueryStringValue (key) {  
  return decodeURIComponent(window.location.search.replace(new RegExp("^(?:.*[&\\?]" + encodeURIComponent(key).replace(/[\.\+\*]/g, "\\$&") + "(?:\\=([^&]*))?)?.*$", "i"), "$1"));  
}  

// Would write the value of the QueryString-variable called name to the console  
console.log(getQueryStringValue("name")); 

In modern browsers

In modern browsers you have the searchParams property of the URL interface, which returns a URLSearchParams object. The returned object has a number of convenient methods, including a get-method. So the equivalent of the above example would be:

let params = (new URL(document.location)).searchParams;
let name = params.get("name");

The URLSearchParams interface can also be used to parse strings in a querystring format, and turn them into a handy URLSearchParams object.

let paramsString = "name=foo&age=1337"
let searchParams = new URLSearchParams(paramsString);

searchParams.has("name") === true; // true
searchParams.get("age") === "1337"; // true

Notice that the browser support is still limited on this interface, so if you need to support legacy browsers, stick with the first example or use a polyfill.

${#var} returns the length of var

${var:pos:N} returns N characters from pos onwards

Examples:

$ words="abc"
$ echo ${words:0:1}
a
$ echo ${words:1:1}
b
$ echo ${words:2:1}
c

so it is easy to iterate.

another way:

$ grep -o . <<< "abc"
a
b
c

or

$ grep -o . <<< "abc" | while read letter;  do echo "my letter is $letter" ; done 

my letter is a
my letter is b
my letter is c

I spent my whole day today investigating this problem and none of the answers helped. Here is my scenario. The WebApplicationInitializer types in my case are inside jar files. we have a multi-module gradle web project where each module is packaged as a jar and included in the web artifact. The problem is that Apache tomcat's classloader is not looking for the implementations of WebApplicationIntializer in WEB-INF/lib instead its looking for those types directly under WEB-INF/classes folder.

Here is what I ended up doing for anyone who faces this problem in future.

I implemented a ServletContainerInitializer myself and added that class name to META-INF/services/javax.servlet.ServletContainerInitializer

In the implementation, I copied the code from SpringServletContainerIntializer and used reflections to find the classes implementing a CustomWebApplicationInitializer interface, I did not make use of spring's WebApplicationInitializer interface to avoid any conflicts. Basically I have the same contract as WebApplicationInitializer with a different name. Now on startup, my container initializer is called and I delegated the call to all my CustomWebApplicationInitializers.

Based on my search I also found that the loader used for tomcat can be updated to have it search in WEB-INF/lib but I have little control over the tomcat I deploy my app to so went with the above solution. Hope this helps someone.

It's may be due difference reportviewer version in your project and VS

Another way to get the number of occurrences of each item, in a dictionary:

dict((i, a.count(i)) for i in a)

You didn't mention any specifics about your target environment or constraints, so this may not be entirely applicable... but if you're looking for a way to effectively track an evolving DB schema and aren't adverse to the idea of using Ruby, ActiveRecord's migrations are right up your alley.

Migrations programatically define database transformations using a Ruby DSL; each transformation can be applied or (usually) rolled back, allowing you to jump to a different version of your DB schema at any given point in time. The file defining these transformations can be checked into version control like any other piece of source code.

Because migrations are a part of ActiveRecord, they typically find use in full-stack Rails apps; however, you can use ActiveRecord independent of Rails with minimal effort. See here for a more detailed treatment of using AR's migrations outside of Rails.

For Laravel ^5

Orders::max('id');

I used it is short and best;

both are the same, but array_push makes a loop in it's parameter which is an array and perform $array[]=$element

All design patterns are some classes arranged in some way or other that suits a specific application. The purpose of facade pattern is to hide the complexity of an operation or operations. You can see an example and learn facade pattern from http://preciselyconcise.com/design_patterns/facade.php

I had this problem couple of weeks ago. I first tried the troubleshooting on the Android developer site, but without luck. After that I reinstalled the Android SDK, which solved my problem.

Linux.

$ apt-get install beep

$ python
>>> os.system("beep -f 555 -l 460")

OR

$ beep -f 659 -l 460 -n -f 784 -l 340 -n -f 659 -l 230 -n -f 659 -l 110 -n -f 880 -l 230 -n -f 659 -l 230 -n -f 587 -l 230 -n -f 659 -l 460 -n -f 988 -l 340 -n -f 659 -l 230 -n -f 659 -l 110 -n -f 1047-l 230 -n -f 988 -l 230 -n -f 784 -l 230 -n -f 659 -l 230 -n -f 988 -l 230 -n -f 1318 -l 230 -n -f 659 -l 110 -n -f 587 -l 230 -n -f 587 -l 110 -n -f 494 -l 230 -n -f 740 -l 230 -n -f 659 -l 460

To name a few we can use redux-react-session which is having good API for session management like, initSessionService, refreshFromLocalStorage, checkAuth and many other. It also provide some advanced functionality like Immutable JS.

Alternatively we can leverage react-web-session which provides options like callback and timeout.

In my instance it had nothing to do with spaces in the file name. I used the MSI installer custom configuration and opted to exclude the default databases, assuming it was just something like Northwind/Adventureworks. Nope, it includes the core MySql system database... once I added that to the installation it worked.

You can simply access like

Context mContext;

public View onCreateView(LayoutInflater inflater,
                             @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {

mContext = getActivity();

}

and then use

FragmentManager fm = ((FragmentActivity) mContext)
                        .getSupportFragmentManager();

I met the same problem, the situation is I need to download flash game by embed tag and H5 game by iframe, I need a loading box there, when the flash or H5 download done, let the loading box display none. well, the flash one work well but when things go to iframe, I cannot find the property 'style' of null , so I add a clock to it , and it works

let clock = setInterval(() => {
        clearInterval(clock)
        clock = null
        document.getElementById('loading-box').style.display = 'none'
    }, 200)

If you have many cases and do not want to write a ton of strcmp() calls, you could do something like:

switch(my_hash_function(the_string)) {
    case HASH_B1: ...
    /* ...etc... */
}

You just have to make sure your hash function has no collisions inside the set of possible values for the string.

You want to treat dot (.) like comma (,). So, replace

if (double.TryParse(values[i, j], out tmp))

with

if (double.TryParse(values[i, j].Replace('.', ','), out tmp))

If I understand correctly, you want to get the String of an Editable object, right? If yes, try using toString().

First of all you need to install json-loader:

npm i json-loader --save-dev

Then, there are two ways how you can use it:

1. In order to avoid adding json-loader in each import you can add to webpack.config this line:

   loaders: [
     { test: /\.json$/, loader: 'json-loader' },
     // other loaders 
   ]
   

   Then import json files like this

   import suburbs from '../suburbs.json';
   

2. Use json-loader directly in your import, as in your example:

   import suburbs from 'json!../suburbs.json';
   

Note: In webpack 2.* instead of keyword loaders need to use rules.,

also webpack 2.* uses json-loader by default

*.json files are now supported without the json-loader. You may still use it. It's not a breaking change.

v2.1.0-beta.28

    $recipients = "[email protected],[email protected],[email protected],[email protected]";
    $email_array = explode(",",$recipients);
    foreach($email_array as $email)
    {
        echo $to      =  $email;
        $subject = 'the subject';
        $message = 'hello';
       $headers = 'From: [email protected]' . "\r\n" .
       'Reply-To: [email protected]' . "\r\n" .
        'X-Mailer: PHP/' . phpversion();
        mail($to, $subject, $message, $headers);

    }

select * 
from my_table 
where length( Name ) = ( 
      select max( length( Name ) ) 
      from my_table
      limit 1 
);

It this involves two table scans, and so might not be very fast !

I got this error: "Source option 5 is no longer supported. Use 6 or later" after I changed the pom.xml

<java.version>7</java.version>

to

<java.version>11</java.version>

Later to realise the property was used with a dash insteal of a dot:

  <source>${java-version}</source>
  <target>${java-version}</target>

(swearings), I replaced the dot with a dash and the error went away:

<java-version>11</javaversion>

Just to add my answer, it seems that the transitions need to be based on initial values and final values within the css properties to be able to manage the animation.

Those reworked css classes should provide the expected result :

    top:0px;_x000D_
    left:0px;_x000D_

}_x000D_
_x000D_
.box:hover .hidden{_x000D_
    opacity: 1;_x000D_
     width: 500px;_x000D_

I don't think there is any easy way to get only HTTP headers. You have to iterate through request.META dict to get what all you need.

django-debug-toolbar takes the same approach to show header information. Have a look at this file responsible for retrieving header information.

Do not hesitate to put constraints on the database. You'll be sure to have a consistent database, and that's one of the good reasons to use a database. Especially if you have several applications requesting it (or just one application but with a direct mode and a batch mode using different sources).

With MySQL you do not have advanced constraints like you would have in postgreSQL but at least the foreign key constraints are quite advanced.

We'll take an example, a company table with a user table containing people from theses company

CREATE TABLE COMPANY (
     company_id INT NOT NULL,
     company_name VARCHAR(50),
     PRIMARY KEY (company_id)
) ENGINE=INNODB;

CREATE TABLE USER (
     user_id INT, 
     user_name VARCHAR(50), 
     company_id INT,
     INDEX company_id_idx (company_id),
     FOREIGN KEY (company_id) REFERENCES COMPANY (company_id) ON...
) ENGINE=INNODB;

Let's look at the ON UPDATE clause:

• ON UPDATE RESTRICT : the default : if you try to update a company_id in table COMPANY the engine will reject the operation if one USER at least links on this company.
• ON UPDATE NO ACTION : same as RESTRICT.
• ON UPDATE CASCADE : the best one usually : if you update a company_id in a row of table COMPANY the engine will update it accordingly on all USER rows referencing this COMPANY (but no triggers activated on USER table, warning). The engine will track the changes for you, it's good.
• ON UPDATE SET NULL : if you update a company_id in a row of table COMPANY the engine will set related USERs company_id to NULL (should be available in USER company_id field). I cannot see any interesting thing to do with that on an update, but I may be wrong.

And now on the ON DELETE side:

• ON DELETE RESTRICT : the default : if you try to delete a company_id Id in table COMPANY the engine will reject the operation if one USER at least links on this company, can save your life.
• ON DELETE NO ACTION : same as RESTRICT
• ON DELETE CASCADE : dangerous : if you delete a company row in table COMPANY the engine will delete as well the related USERs. This is dangerous but can be used to make automatic cleanups on secondary tables (so it can be something you want, but quite certainly not for a COMPANY<->USER example)
• ON DELETE SET NULL : handful : if you delete a COMPANY row the related USERs will automatically have the relationship to NULL. If Null is your value for users with no company this can be a good behavior, for example maybe you need to keep the users in your application, as authors of some content, but removing the company is not a problem for you.

usually my default is: ON DELETE RESTRICT ON UPDATE CASCADE. with some ON DELETE CASCADE for track tables (logs--not all logs--, things like that) and ON DELETE SET NULL when the master table is a 'simple attribute' for the table containing the foreign key, like a JOB table for the USER table.

Edit

It's been a long time since I wrote that. Now I think I should add one important warning. MySQL has one big documented limitation with cascades. Cascades are not firing triggers. So if you were over confident enough in that engine to use triggers you should avoid cascades constraints.

• http://dev.mysql.com/doc/refman/5.6/en/triggers.html

MySQL triggers activate only for changes made to tables by SQL statements. They do not activate for changes in views, nor by changes to tables made by APIs that do not transmit SQL statements to the MySQL Server

• http://dev.mysql.com/doc/refman/5.6/en/stored-program-restrictions.html#stored-routines-trigger-restrictions

==> See below the last edit, things are moving on this domain

Triggers are not activated by foreign key actions.

And I do not think this will get fixed one day. Foreign key constraints are managed by the InnoDb storage and Triggers are managed by the MySQL SQL engine. Both are separated. Innodb is the only storage with constraint management, maybe they'll add triggers directly in the storage engine one day, maybe not.

But I have my own opinion on which element you should choose between the poor trigger implementation and the very useful foreign keys constraints support. And once you'll get used to database consistency you'll love PostgreSQL.

12/2017-Updating this Edit about MySQL:

as stated by @IstiaqueAhmed in the comments, the situation has changed on this subject. So follow the link and check the real up-to-date situation (which may change again in the future).

You can have it this way:

It is important to mind the commas after each struct item or set of items.

earnings := []LineItemsType{

        LineItemsType{

            TypeName: "Earnings",

            Totals: 0.0,

            HasTotal: true,

            items: []LineItems{

                LineItems{

                    name: "Basic Pay",

                    amount: 100.0,
                },

                LineItems{

                    name: "Commuter Allowance",

                    amount: 100.0,
                },
            },
        },
        LineItemsType{

            TypeName: "Earnings",

            Totals: 0.0,

            HasTotal: true,

            items: []LineItems{

                LineItems{

                    name: "Basic Pay",

                    amount: 100.0,
                },

                LineItems{

                    name: "Commuter Allowance",

                    amount: 100.0,
                },
            },
        },
    }

What are the possible ways to do that such as any SQL query to import .sql file ?

Try this

 mysql -u<user> -p<password> <database name> < /path/to/dump.sql

assuming dump.sql is your 1 GB dump file

If I understand your question correctly, you are asking how you can create class level constants (static - in C++ parlance) such that you don't a) replicate the overhead in every instance, and b have to recompute what is otherwise constant.

The language has evolved - as every reader knows, but as I test this in Xcode 6.3.1, the solution is:

import Swift

class MyClass {
    static let testStr = "test"
    static let testStrLen = count(testStr)

    init() {
        println("There are \(MyClass.testStrLen) characters in \(MyClass.testStr)")
    }
}

let a = MyClass()

// -> There are 4 characters in test

I don't know if the static is strictly necessary as the compiler surely only adds only one entry per const variable into the static section of the binary, but it does affect syntax and access. By using static, you can refer to it even when you don't have an instance: MyClass.testStrLen.

There is way with add class and css style

![pic][logo]{.classname}

then write down link and css below

[logo]: (picurl)

<style type="text/css">
    .classname{
        width: 200px;
    }
</style>

Reference Here

The easiest way is this.

byte[] bytes = rs.getBytes("my_field");

Another way is to use FIXED function, you can specify the number of decimal places but it defaults to 2 if the places aren't specified, i.e.

=FIXED(E5,2)

or just

=FIXED(E5)

"matt b" has it right, but to be specific, the "install" goal copies your built target to the local repository on your file system; useful for small changes across projects not currently meant for the full group.

The "deploy" goal uploads it to your shared repository for when your work is finished, and then can be shared by other people who require it for their project.

In your case, it seems that "install" is used to make the management of the deployment easier since CI's local repo is the shared repo. If CI was on another box, it would have to use the "deploy" goal.

On Linux, I often use curl with the --head parameter. It is available for several operating systems, including Windows.

[edit] related to the answer below, gknw.net is currently down as of February 23 2012. Check curl.haxx.se for updated info.

In addition to Gusev Slava's answer, you might want to use groupby's groups:

{key: df.loc[value] for key, value in df.groupby("name").groups.items()}

This will yield a dictionary with the keys you have grouped by, pointing to the corresponding partitions. The advantage is that the keys are maintained and don't vanish in the list index.

You can also use the matrix command, to create a matrix with n lines and m columns, filled with zeros.

matrix(0, n, m)

You can use the directive v-el to save an element and then use it later.

tl;dr

The other Answers are outmoded as of Java 8.

Instant                           // Represent a moment in UTC. 
.parse( "2013-09-29T18:46:19Z" )  // Parse text in standard ISO 8601 format where the `Z` means UTC, pronounces “Zulu”.
.atZone(                          // Adjust from UTC to a time zone. 
    ZoneId.of( "Asia/Kolkata" )
)                                 // Returns a `ZonedDateTime` object. 

ISO 8601

Your string format happens to comply with the ISO 8601 standard. This standard defines sensible formats for representing various date-time values as text.

java.time

The old java.util.Date/.Calendar and java.text.SimpleDateFormat classes have been supplanted by the java.time framework built into Java 8 and later. See Tutorial. Avoid the old classes as they have proven to be poorly designed, confusing, and troublesome.

Part of the poor design in the old classes has bitten you, where the toString method applies the JVM's current default time zone when generating a text representation of the date-time value that is actually in UTC (GMT); well-intentioned but confusing.

The java.time classes use ISO 8601 formats by default when parsing/generating textual representations of date-time values. So no need to specify a parsing pattern.

An Instant is a moment on the timeline in UTC.

Instant instant = Instant.parse( "2013-09-29T18:46:19Z" );

You can apply a time zone as needed to produce a ZonedDateTime object.

ZoneId zoneId = ZoneId.of( "America/Montreal" );
ZonedDateTime zdt = instant.atZone( zoneId );

The examples have very different outcomes.

Before looking at the differences, the following should be noted:

• A constructor's prototype provides a way to share methods and values among instances via the instance's private [[Prototype]] property.
• A function's this is set by how the function is called or by the use of bind (not discussed here). Where a function is called on an object (e.g. myObj.method()) then this within the method references the object. Where this is not set by the call or by the use of bind, it defaults to the global object (window in a browser) or in strict mode, remains undefined.
• JavaScript is an object-oriented language, i.e. most values are objects, including functions. (Strings, numbers, and booleans are not objects.)

So here are the snippets in question:

var A = function () {
    this.x = function () {
        //do something
    };
};

In this case, variable A is assigned a value that is a reference to a function. When that function is called using A(), the function's this isn't set by the call so it defaults to the global object and the expression this.x is effective window.x. The result is that a reference to the function expression on the right-hand side is assigned to window.x.

In the case of:

var A = function () { };
A.prototype.x = function () {
    //do something
};

something very different occurs. In the first line, variable A is assigned a reference to a function. In JavaScript, all functions objects have a prototype property by default so there is no separate code to create an A.prototype object.

In the second line, A.prototype.x is assigned a reference to a function. This will create an x property if it doesn't exist, or assign a new value if it does. So the difference with the first example in which object's x property is involved in the expression.

Another example is below. It's similar to the first one (and maybe what you meant to ask about):

var A = new function () {
    this.x = function () {
        //do something
    };
};

In this example, the new operator has been added before the function expression so that the function is called as a constructor. When called with new, the function's this is set to reference a new Object whose private [[Prototype]] property is set to reference the constructor's public prototype. So in the assignment statement, the x property will be created on this new object. When called as a constructor, a function returns its this object by default, so there is no need for a separate return this; statement.

To check that A has an x property:

console.log(A.x) // function () {
                 //   //do something
                 // };

This is an uncommon use of new since the only way to reference the constructor is via A.constructor. It would be much more common to do:

var A = function () {
    this.x = function () {
        //do something
    };
};
var a = new A();

Another way of achieving a similar result is to use an immediately invoked function expression:

var A = (function () {
    this.x = function () {
        //do something
    };
}());

In this case, A assigned the return value of calling the function on the right-hand side. Here again, since this is not set in the call, it will reference the global object and this.x is effective window.x. Since the function doesn't return anything, A will have a value of undefined.

These differences between the two approaches also manifest if you're serializing and de-serializing your Javascript objects to/from JSON. Methods defined on an object's prototype are not serialized when you serialize the object, which can be convenient when for example you want to serialize just the data portions of an object, but not it's methods:

var A = function () { 
    this.objectsOwnProperties = "are serialized";
};
A.prototype.prototypeProperties = "are NOT serialized";
var instance = new A();
console.log(instance.prototypeProperties); // "are NOT serialized"
console.log(JSON.stringify(instance)); 
// {"objectsOwnProperties":"are serialized"} 

Related questions:

• What does it mean that JavaScript is a prototypal language?
• What is the scope of a function in JavaScript?
• How does the "this" keyword work?

Sidenote: There may not be any significant memory savings between the two approaches, however using the prototype to share methods and properties will likely use less memory than each instance having its own copy.

JavaScript isn't a low-level language. It may not be very valuable to think of prototyping or other inheritance patterns as a way to explicitly change the way memory is allocated.

If you use android studio, this might be useful for you.

I had a similar problem and i solved it by changing the skd path from the default C:\Program Files (x86)\Android\android-studio\sdk to C:\Program Files (x86)\Android\android-sdk .

It seems the problem came from the compiler version (gradle sets it automatically to the highest one available in the sdk folder) which doesn't support this theme, and since android studio had only the api 7 in its sdk folder, it gave me this error.

Create the Intent like this:

   Uri uriSms = Uri.parse("smsto:1234567899");   
   Intent intentSMS = new Intent(Intent.ACTION_SENDTO, uriSms);   
   intentSMS.putExtra("sms_body", "The SMS text");   
   startActivity(intentSMS); 

The toggleOption function is not perfect and introduced nasty bugs in my application. jQuery will get confused with .val() and .arraySerialize() Try to select options 4 and 5 to see what I mean:

<select id="t">
<option value="v1">options 1</option>
<option value="v2">options 2</option>
<option value="v3" id="o3">options 3</option>
<option value="v4">options 4</option>
<option value="v5">options 5</option>
</select>
<script>
jQuery.fn.toggleOption = function( show ) {
    jQuery( this ).toggle( show );
    if( show ) {
        if( jQuery( this ).parent( 'span.toggleOption' ).length )
            jQuery( this ).unwrap( );
    } else {
        jQuery( this ).wrap( '<span class="toggleOption" style="display: none;" />' );
    }
};

$("#o3").toggleOption(false); 
$("#t").change(function(e) {
    if($(this).val() != this.value) {
    console.log("Error values not equal", this.value, $(this).val());

With Bootstrap 2.0 you can give your tabs the "stackable" class, which makes them stack vertically.

The error says "The index is out of range". That means you were trying to index an object with a value that was not valid. If you have two books, and I ask you to give me your third book, you will look at me funny. This is the computer looking at you funny. You said - "create a collection". So it did. But initially the collection is empty: not only is there nothing in it - it has no space to hold anything. "It has no hands".

Then you said "the first element of the collection is now 'ItemID'". And the computer says "I never was asked to create space for a 'first item'." I have no hands to hold this item you are giving me.

In terms of your code, you created a view, but never specified the size. You need a

dataGridView1.ColumnCount = 5;

Before trying to access any columns. Modify

DataGridView dataGridView1 = new DataGridView();

dataGridView1.Columns[0].Name = "ItemID";

to

DataGridView dataGridView1 = new DataGridView();
dataGridView1.ColumnCount = 5;
dataGridView1.Columns[0].Name = "ItemID";

See http://msdn.microsoft.com/en-us/library/system.windows.forms.datagridview.columncount.aspx

Put this code where you define recycler view in activity.

    rv_list.addOnItemTouchListener(
            new RecyclerItemClickListener(activity, new RecyclerItemClickListener.OnItemClickListener() {
                @Override
                public void onItemClick(View v, int position) {

                    Toast.makeText(activity, "" + position, Toast.LENGTH_SHORT).show();
                }
            })
    );

Then make separate class and put this code:

import android.content.Context;
import android.support.v7.widget.RecyclerView;
import android.view.GestureDetector;
import android.view.MotionEvent;
import android.view.View;
public class RecyclerItemClickListener implements RecyclerView.OnItemTouchListener {

    private OnItemClickListener mListener;
    public interface OnItemClickListener {
        public void onItemClick(View view, int position);
    }
    GestureDetector mGestureDetector;
    public RecyclerItemClickListener(Context context, OnItemClickListener listener) {
        mListener = listener;
        mGestureDetector = new GestureDetector(context, new GestureDetector.SimpleOnGestureListener() {
            @Override
            public boolean onSingleTapUp(MotionEvent e) {
                return true;
            }
        });
    }
    @Override
    public boolean onInterceptTouchEvent(RecyclerView view, MotionEvent e) {
        View childView = view.findChildViewUnder(e.getX(), e.getY());
        if (childView != null && mListener != null && mGestureDetector.onTouchEvent(e)) {
            mListener.onItemClick(childView, view.getChildAdapterPosition(childView));
        }
        return false;
    }

    @Override
    public void onTouchEvent(RecyclerView view, MotionEvent motionEvent) {
    }

    @Override
    public void onRequestDisallowInterceptTouchEvent(boolean disallowIntercept) {

    }
}

Based on @hajili's contribution (which is a creative use of the parsename function, intended to parse the name of an object that is period-separated), I modified it so it can handle cases where the data doesn't containt a middle name or when the name is "John and Jane Doe". It's not 100% perfect but it's compact and might do the trick depending on the business case.

SELECT NAME,
CASE WHEN parsename(replace(NAME, ' ', '.'), 4) IS NOT NULL THEN 
   parsename(replace(NAME, ' ', '.'), 4) ELSE
    CASE WHEN parsename(replace(NAME, ' ', '.'), 3) IS NOT NULL THEN 
    parsename(replace(NAME, ' ', '.'), 3) ELSE
   parsename(replace(NAME, ' ', '.'), 2) end END as FirstName
   ,
CASE WHEN parsename(replace(NAME, ' ', '.'), 3) IS NOT NULL THEN 
   parsename(replace(NAME, ' ', '.'), 2) ELSE NULL END as MiddleName,
   parsename(replace(NAME, ' ', '.'), 1) as LastName

The ** never properly worked before, but since git 1.8.2 (March, 8th 2013), it seems to be explicitly mentioned and supported:

The patterns in .gitignore and .gitattributes files can have **/, as a pattern that matches 0 or more levels of subdirectory.

E.g. "foo/**/bar" matches "bar" in "foo" itself or in a subdirectory of "foo".

In your case, that means this line might now be supported:

/main/**/bin/

From the OData documentation:

The OData Protocol is an application-level protocol for interacting with data via RESTful web services.

...

The OData Protocol is different from other REST-based web service approaches in that it provides a uniform way to describe both the data and the data model.

If you have an array of objects and want to flatten it with a node, just use this function:

function objectArray_flatten($array,$childField) {
    $result = array();
    foreach ($array as $node)
    {
        $result[] = $node;
        if(isset($node->$childField))
        {
            $result = array_merge(
                $result, 
                objectArray_flatten($node->$childField,$childField)
            );
            unset($node->$childField);
        }

    }
    return $result;
}

Well the answer was sitting right in front of me the whole time.

In SQL Server Management Studio 2008 there is a Debug button in the toolbar. Set a break point in a query window to step through.

I dismissed this functionality at the beginning because I didn't think of stepping INTO the stored procedure, which you can do with ease.

SSMS basically does what FinnNK mentioned with the MSDN walkthrough but automatically.

So easy! Thanks for your help FinnNK.

Edit: I should add a step in there to find the stored procedure call with parameters I used SQL Profiler on my database.

I wasn't quite sure where I would store the start position, so I want to elaborate on David Boikes comment. I found that I could store that variable in the ui.item object itself and retrieve it in the stop function as so:

$( "#sortable" ).sortable({
    start: function(event, ui) {
        ui.item.startPos = ui.item.index();
    },
    stop: function(event, ui) {
        console.log("Start position: " + ui.item.startPos);
        console.log("New position: " + ui.item.index());
    }
});
