I would like to re-structure the statement that you mentioned which is:

This means that the state as consumed by your target component can have a wildly different structure from the state as it is stored on your store

You can say that the state consumed by your target component has a small portion of the state that is stored on the redux store. In other words, the state consumed by your component would be the sub-set of the state of the redux store.

As far as understanding the connect() method is concerned, it's fairly simple! connect() method has the power to add new props to your component and even override existing props. It is through this connect method that we can access the state of the redux store as well which is thrown to us by the Provider. A combination of which works in your favor and you get to add the state of your redux store to the props of your component.

Above is some theory and I would suggest you look at this video once to understand the syntax better.

You can set display attribute as none to hide a label.

<label id="excel-data-div" style="display: none;"></label>

Are you looking for something like this?

SELECT CASE WHEN LEFT(created_ts, 1) LIKE '[0-9]' 
            THEN CONVERT(VARCHAR(10), CONVERT(datetime, created_ts,   1), 101)
            ELSE CONVERT(VARCHAR(10), CONVERT(datetime, created_ts, 109), 101)
      END created_ts
  FROM table1

Output:

| CREATED_TS |

Here is SQLFiddle demo

Reading an html page with urllib is fairly simple to do. Since you want to read it as a single string I will show you.

Import urllib.request:

#!/usr/bin/python3.5

import urllib.request

Prepare our request

request = urllib.request.Request('http://www.w3schools.com')

Always use a "try/except" when requesting a web page as things can easily go wrong. urlopen() requests the page.

try:
    response = urllib.request.urlopen(request)
except:
    print("something wrong")

Type is a great function that will tell us what 'type' a variable is. Here, response is a http.response object.

print(type(response))

The read function for our response object will store the html as bytes to our variable. Again type() will verify this.

htmlBytes = response.read()

print(type(htmlBytes))

Now we use the decode function for our bytes variable to get a single string.

htmlStr = htmlBytes.decode("utf8")

print(type(htmlStr))

If you do want to split up this string into separate lines, you can do so with the split() function. In this form we can easily iterate through to print out the entire page or do any other processing.

htmlSplit = htmlStr.split('\n')

print(type(htmlSplit))

for line in htmlSplit:
    print(line)

Hopefully this provides a little more detailed of an answer. Python documentation and tutorials are great, I would use that as a reference because it will answer most questions you might have.

You can use MERGE Statement, This statement is used to insert data if not exist or update if does exist.

MERGE INTO Employee AS e
using EmployeeUpdate AS eu
ON e.EmployeeID = eu.EmployeeID`

Truncate the contents of a variable

$ var="abcde"; echo ${var%d*}
abc

Make substitutions similar to sed

$ var="abcde"; echo ${var/de/12}
abc12

Use a default value

$ default="hello"; unset var; echo ${var:-$default}
hello

schema definition as simple string

Just in case if some one is interested in schema definition as simple string with date and time stamp

data file creation from Terminal or shell

echo " 
2019-07-02 22:11:11.000999, 01/01/2019, Suresh, abc  
2019-01-02 22:11:11.000001, 01/01/2020, Aadi, xyz 
" > data.csv

Defining the schema as String

    user_schema = 'timesta TIMESTAMP,date DATE,first_name STRING , last_name STRING'

reading the data

    df = spark.read.csv(path='data.csv', schema = user_schema, sep=',', dateFormat='MM/dd/yyyy',timestampFormat='yyyy-MM-dd HH:mm:ss.SSSSSS')

    df.show(10, False)

    +-----------------------+----------+----------+---------+
    |timesta                |date      |first_name|last_name|
    +-----------------------+----------+----------+---------+
    |2019-07-02 22:11:11.999|2019-01-01| Suresh   | abc     |
    |2019-01-02 22:11:11.001|2020-01-01| Aadi     | xyz     |
    +-----------------------+----------+----------+---------+

Please note defining the schema explicitly instead of letting spark infer the schema also improves the spark read performance.

You want to get the computed width. Try: .offsetWidth

(I.e: this.offsetWidth='50px' or var w=this.offsetWidth)

In my case I had to remove React Dev Tools from Chrome to stop seeing the strange errors during development of React app using a local Express server with a create-react-app client (which uses Webpack). In the interest of community I did a sanity check and quit everything - server/client server/Chrome - and then I opened Chrome and reinstalled React Dev Tools... Started things back up and am seeing this funky address and error again:

For Swift 3

UserDefaults.standard.setValue(token, forKey: "user_auth_token")
print("\(UserDefaults.standard.value(forKey: "user_auth_token")!)")

jQuery:

$('#foo').click(function() { alert('foo'); });

Or if you don't want it to follow the link href:

$('#foo').click(function() { alert('foo'); return false; });

I would recommend adding a boolean check for the magnitude of the number. I'm converting a high milliseconds value to datetime. I have numbers from 2 to 200,000,200 so 0 is a valid output. The function as @Chris Mueller has it will return 0 even if number is smaller than 10**n.

def get_digit(number, n):
    return number // 10**n % 10

get_digit(4231, 5)
# 0

def get_digit(number, n):
    if number - 10**n < 0:
        return False
    return number // 10**n % 10

get_digit(4321, 5)
# False

You do have to be careful when checking the boolean state of this return value. To allow 0 as a valid return value, you cannot just use if get_digit:. You have to use if get_digit is False: to keep 0 from behaving as a false value.

Create the Button and add it to Form.Controls list to display it on your form:

Button buttonOk = new Button();
buttonOk.Location = new Point(295, 45);  //or what ever position you want it to give
buttonOk.Text = "OK"; //or what ever you want to write over it
buttonOk.Click += new EventHandler(buttonOk_Click);
this.Controls.Add(buttonOk); //here you add it to the Form's Controls list

Create the button click method here:

void buttonOk_Click(object sender, EventArgs e)
        {
            MessageBox.Show("clicked");
            this.Close(); //all your choice to close it or remove this line
        }

For those about to hack:

    public static int GetNativeThreadId(Thread thread)
    {
        var f = typeof(Thread).GetField("DONT_USE_InternalThread",
            BindingFlags.GetField | BindingFlags.NonPublic | BindingFlags.Instance);

        var pInternalThread = (IntPtr)f.GetValue(thread);
        var nativeId = Marshal.ReadInt32(pInternalThread, (IntPtr.Size == 8) ? 548 : 348); // found by analyzing the memory
        return nativeId;
    }

This line is a problem:

ADD ../../home/ubuntu/.ssh/id_rsa /root/.ssh/id_rsa

When specifying the files you want to copy into the image you can only use relative paths - relative to the directory where your Dockerfile is. So you should instead use:

ADD id_rsa /root/.ssh/id_rsa

And put the id_rsa file into the same directory where your Dockerfile is.

I wanna submit my project : https://github.com/flyingangel/argparser

source argparser.sh
parse_args "$@"

Simple as that. The environment will be populated with variables with the same name as the arguments

Inside of VBS you can access parameters with

Wscript.Arguments(0)
Wscript.Arguments(1)

and so on. The number of parameter:

Wscript.Arguments.Count

The obvious thing to do is read the documentation.

But to help: substr($str, $start, $end);

$str is your text

$start is the character index to begin at. In your case, it is likely 0 which means the very beginning.

$end is where to truncate at. Suppose you wanted to end at 15 characters, for example. You would write it like this:

<?php

$text = "long text that should be truncated";
echo substr($text, 0, 15);

?>

and you would get this:

long text that 

makes sense?

EDIT

The link you gave is a function to find the last white space after chopping text to a desired length so you don't cut off in the middle of a word. However, it is missing one important thing - the desired length to be passed to the function instead of always assuming you want it to be 25 characters. So here's the updated version:

function truncate($text, $chars = 25) {
    if (strlen($text) <= $chars) {
        return $text;
    }
    $text = $text." ";
    $text = substr($text,0,$chars);
    $text = substr($text,0,strrpos($text,' '));
    $text = $text."...";
    return $text;
}

So in your case you would paste this function into the functions.php file and call it like this in your page:

$post = the_post();
echo truncate($post, 100);

This will chop your post down to the last occurrence of a white space before or equal to 100 characters. Obviously you can pass any number instead of 100. Whatever you need.

You can use the try..catch statement in java, to capture an exception that may arise from Integer.parseInt().

Example:

try {
  int i = Integer.parseint(stringToParse);
  //parseInt succeded
} catch(Exception e)
{
   //parseInt failed
}

If you know x and y are both strings, using === is not strictly necessary, but is still good practice.

Assuming both variables actually are strings, both operators will function identically. However, TS often allows you to pass an object that meets all the requirements of string rather than an actual string, which may complicate things.

Given the possibility of confusion or changes in the future, your linter is probably correct in demanding ===. Just go with that.

I'm using SSH to authenticate my GitHub account and have a couple dependencies in my project installed as follows:

"dependencies": {
  "<dependency name>": "git+ssh://[email protected]/<github username>/<repository name>.git#<release version | branch>"
}

Have same error from time to time (when I set install location to "prefer external" in manifest). Just clean and rebuild project. Works for me.

Another small tip: when going the batch file route, I like to be able to abort it in case I run it accidentally. So the batch file invokes the shutdown but leaves you at the command prompt afterwards.

@echo off
echo Shutting down in 10 seconds. Please type "shutdown /a" to abort.
cmd.exe /K shutdown /f /t 10 /r

Plus, since it's on a timer, you get about the same thrill as you do when hunting in The Oregon Trail.

Unfortunatelly, for IIS installed on Windows 7/8 machines, there is no option to create users only for IIS authentification. For Windows Server there is that option where you can add users from IIS Manager UI. These users have roles only on IIS, but not for the rest of the system. In this article it shows how you add users, but it is incorrect stating that is also appliable to standard OS, it only applies to server versions.

The fully RFC 822 compliant regex is inefficient and obscure because of its length. Fortunately, RFC 822 was superseded twice and the current specification for email addresses is RFC 5322. RFC 5322 leads to a regex that can be understood if studied for a few minutes and is efficient enough for actual use.

One RFC 5322 compliant regex can be found at the top of the page at http://emailregex.com/ but uses the IP address pattern that is floating around the internet with a bug that allows 00 for any of the unsigned byte decimal values in a dot-delimited address, which is illegal. The rest of it appears to be consistent with the RFC 5322 grammar and passes several tests using grep -Po, including cases domain names, IP addresses, bad ones, and account names with and without quotes.

Correcting the 00 bug in the IP pattern, we obtain a working and fairly fast regex. (Scrape the rendered version, not the markdown, for actual code.)

or:

Here is diagram of finite state machine for above regexp which is more clear than regexp itself

The more sophisticated patterns in Perl and PCRE (regex library used e.g. in PHP) can correctly parse RFC 5322 without a hitch. Python and C# can do that too, but they use a different syntax from those first two. However, if you are forced to use one of the many less powerful pattern-matching languages, then it’s best to use a real parser.

It's also important to understand that validating it per the RFC tells you absolutely nothing about whether that address actually exists at the supplied domain, or whether the person entering the address is its true owner. People sign others up to mailing lists this way all the time. Fixing that requires a fancier kind of validation that involves sending that address a message that includes a confirmation token meant to be entered on the same web page as was the address.

Confirmation tokens are the only way to know you got the address of the person entering it. This is why most mailing lists now use that mechanism to confirm sign-ups. After all, anybody can put down [email protected], and that will even parse as legal, but it isn't likely to be the person at the other end.

For PHP, you should not use the pattern given in Validate an E-Mail Address with PHP, the Right Way from which I quote:

There is some danger that common usage and widespread sloppy coding will establish a de facto standard for e-mail addresses that is more restrictive than the recorded formal standard.

That is no better than all the other non-RFC patterns. It isn’t even smart enough to handle even RFC 822, let alone RFC 5322. This one, however, is.

If you want to get fancy and pedantic, implement a complete state engine. A regular expression can only act as a rudimentary filter. The problem with regular expressions is that telling someone that their perfectly valid e-mail address is invalid (a false positive) because your regular expression can't handle it is just rude and impolite from the user's perspective. A state engine for the purpose can both validate and even correct e-mail addresses that would otherwise be considered invalid as it disassembles the e-mail address according to each RFC. This allows for a potentially more pleasing experience, like

The specified e-mail address 'myemail@address,com' is invalid. Did you mean '[email protected]'?

I struggled for a couple of days to find anything that would work for me as was passing multiple arrays of ids and returning a blob. Turns out if using .NET CORE I'm using 2.1, you need to use [FromBody] and as can only use once you need to create a viewmodel to hold the data.

Wrap up content like below,

var params = {
            "IDs": IDs,
            "ID2s": IDs2,
            "id": 1
        };

In my case I had already json'd the arrays and passed the result to the function

var IDs = JsonConvert.SerializeObject(Model.Select(s => s.ID).ToArray());

Then call the XMLHttpRequest POST and stringify the object

var ajax = new XMLHttpRequest();
ajax.open("POST", '@Url.Action("MyAction", "MyController")', true);
ajax.responseType = "blob";
ajax.setRequestHeader("Content-Type", "application/json;charset=UTF-8");           
ajax.onreadystatechange = function () {
    if (this.readyState == 4) {
       var blob = new Blob([this.response], { type: "application/octet-stream" });
       saveAs(blob, "filename.zip");
    }
};

ajax.send(JSON.stringify(params));

Then have a model like this

public class MyModel
{
    public int[] IDs { get; set; }
    public int[] ID2s { get; set; }
    public int id { get; set; }
}

Then pass in Action like

public async Task<IActionResult> MyAction([FromBody] MyModel model)

git cherry-pick : Apply the changes introduced by some existing commits

Assume we have branch A with (X, Y, Z) commits. We need to add these commits to branch B. We are going to use the cherry-pick operations.

When we use cherry-pick, we should add commits on branch B in the same chronological order that the commits appear in Branch A.

cherry-pick does support a range of commits, but if you have merge commits in that range, it gets really complicated

git checkout B
git cherry-pick SHA-COMMIT-X
git cherry-pick SHA-COMMIT-Y
git cherry-pick SHA-COMMIT-Z

Example of workflow :

We can use cherry-pick with options

-e or --edit : With this option, git cherry-pick will let you edit the commit message prior to committing.

-n or --no-commit : Usually the command automatically creates a sequence of commits. This flag applies the changes necessary to cherry-pick each named commit to your working tree and the index, without making any commit. In addition, when this option is used, your index does not have to match the HEAD commit. The cherry-pick is done against the beginning state of your index.

Here an interesting article concerning cherry-pick.

It's useful if you want to separate allocation from initialization. STL uses placement new to create container elements.

You have to read the API carefully for this methods. Sometimes you can get confused very easily.

It is either:

if (B.class.isInstance(view))

API says: Determines if the specified Object (the parameter) is assignment-compatible with the object represented by this Class (The class object you are calling the method at)

or:

if (B.class.isAssignableFrom(view.getClass()))

API says: Determines if the class or interface represented by this Class object is either the same as, or is a superclass or superinterface of, the class or interface represented by the specified Class parameter

or (without reflection and the recommended one):

if (view instanceof B)

You can do it with window functions

SELECT t.*
FROM
    (SELECT
        *,
        ROW_NUMBER() OVER(PARTITION BY usr_id ORDER BY time_stamp DESC) as r
    FROM lives) as t
WHERE t.r = 1

ROWS UNBOUNDED PRECEDING is no Teradata-specific syntax, it's Standard SQL. Together with the ORDER BY it defines the window on which the result is calculated.

Logically a Windowed Aggregate Function is newly calculated for each row within the PARTITION based on all ROWS between a starting row and an ending row.

Starting and ending rows might be fixed or relative to the current row based on the following keywords:

• CURRENT ROW, the current row
• UNBOUNDED PRECEDING, all rows before the current row -> fixed
• UNBOUNDED FOLLOWING, all rows after the current row -> fixed
• x PRECEDING, x rows before the current row -> relative
• y FOLLOWING, y rows after the current row -> relative

Possible kinds of calculation include:

• Both starting and ending row are fixed, the window consists of all rows of a partition, e.g. a Group Sum, i.e. aggregate plus detail rows
• One end is fixed, the other relative to current row, the number of rows increases or decreases, e.g. a Running Total, Remaining Sum
• Starting and ending row are relative to current row, the number of rows within a window is fixed, e.g. a Moving Average over n rows

So SUM(x) OVER (ORDER BY col ROWS UNBOUNDED PRECEDING) results in a Cumulative Sum or Running Total

11 -> 11
 2 -> 11 +  2                = 13
 3 -> 13 +  3 (or 11+2+3)    = 16
44 -> 16 + 44 (or 11+2+3+44) = 60

I strongly recommend the MahApps it's simply awesome!

select constraint_name,constraint_type 
from user_constraints
where table_name = 'YOUR TABLE NAME';

note: table name should be in caps.

In case you don't know the name of the table then,

select constraint_name,constraint_type,table_name 
from user_constraints;

For varchars, you may need to do something like this:

select convert(varchar(25), NULL) as abc_column into xyz_table

If you try

select '' as abc_column into xyz_table

you may get errors related to truncation, or an issue with null values, once you populate.

You should escape the characters like double quotes in the html string by adding "\"

eg: <h2 class=\"fg-white\">

In java syntax:

rdd.collect().forEach(line -> System.out.println(line));

• Make sure we are not editing any of the default sshd_config properties to skip the error

• Host Verification Failed - Definitely a missing entry of hostname in known_hosts file

• Login to the server where the process is failing and do the following:

  1. Sudo to the user running the process

  2. ssh-copy-id destinationuser@destinationhostname

  3. It will prompt like this for the first time, say yes and it will also ask password for the first time:

     The authenticity of host 'sample.org (205.214.640.91)' can't be established.
     RSA key fingerprint is 97:8c:1b:f2:6f:14:6b:5c:3b:ec:aa:46:46:74:7c:40.
     Are you sure you want to continue connecting (yes/no)? *yes*
     

     Password prompt ? give password

  4. Now from the server where process is running, do ssh destinationuser@destinationhostname. It should login without a password.

     Note: Do not change the default permissions of files in the user's .ssh directory, you will end up with different issues

This makes it 'code block' instead of 'image inclusion'. Just remove the leading spaces.

You can execute it using a function. Example:

var theInstructions = "alert('Hello World'); var x = 100";

var F=new Function (theInstructions);

return(F());

As of April 2014, FileSytem APIs may not be standardized in W3C. Anyone looking at the solution with blob should thread with caution, I guess.

HTML5 rocks heads up

W3C Mailing List on FileSytem API

It looks like the github.com host which jenkins tries to connect to is not listed under the Jenkins user's $HOME/.ssh/known_hosts. Jenkins runs on most distros as the user jenkins and hence has its own .ssh directory to store the list of public keys and known_hosts.

The easiest solution I can think of to fix this problem is:

# Login as the jenkins user and specify shell explicity,
# since the default shell is /bin/false for most
# jenkins installations.
sudo su jenkins -s /bin/bash

cd SOME_TMP_DIR
# git clone YOUR_GITHUB_URL

# Allow adding the SSH host key to your known_hosts

# Exit from su
exit

The problem is that for json.load you should pass a file like object with a read function defined. So either you use json.load(response) or json.loads(response.read()).

Do you want to know if a type is the same type as int64_t or do you want to know if something is 64 bits? Based on your proposed solution, I think you're asking about the latter. In that case, I would do something like

template<typename T>
bool is_64bits() { return sizeof(T) * CHAR_BIT == 64; } // or >= 64

Try this for Windows:

    npm uninstall -g cordova

Try this for MAC:

    sudo npm uninstall -g cordova

You can also add Cordova like this:

1. If You Want To install the previous version of Cordova through the Node Package Manager (npm):

   npm install -g [email protected]
   

2. If You Want To install the latest version of Cordova:

   npm install -g cordova 
   

Enjoy!

To get rid of the first column of NAs, you can do it with negative indexing (which removes indices from the R data set). For example:

output = matrix(1:6, 2, 3) # gives you a 2 x 3 matrix filled with the numbers 1 to 6

# output = 
#           [,1] [,2] [,3]
#     [1,]    1    3    5
#     [2,]    2    4    6

output = output[,-1] # this removes column 1 for all rows

# output = 
#           [,1] [,2]
#     [1,]    3    5
#     [2,]    4    6

So you can just add output = output[,-1]after the for loop in your original code.

in SQL 2017 You can do it more easily in the toolbar to the right just hit

the SQL button then its gonna apear the query with the top 200 you edit until the quantity that You want and Execute the query and Done! just Edit

public static String showDate(){
    SimpleDateFormat df=new SimpleDateFormat("\nTime:yyyy-MM-dd HH:mm:ss");
    System.out.println(df.format(new Date()));
    String s=df.format(new Date());
    return s;
}

I think this code may solve your problem.

Linux / Ubuntu Users Step 1:

Instance: instance means just creating a reference(copy).

object: means when memory location is associated with the object (is a run-time entity of the class) by using the new operator.

In simple words, Instance refers to the copy of the object at a particular time whereas object refers to the memory address of the class.

On CentOS EL 6 and perhaps on earlier versions there is one way to get into this same mess.

Install CentOS EL6 with a minimal installation. For example I used kickstart to install the following:

%packages
@core
acpid
bison
cmake
dhcp-common
flex
gcc
gcc-c++
git
libaio-devel
make
man
ncurses-devel
perl
ntp
ntpdate
pciutils
tar
tcpdump
wget
%end

You will find that one of the dependencies of the above list is mysql-libs. I found that my system has a default my.cnf in /etc and this contains:

[mysqld]
dataddir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
user=mysql
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0

[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid

When you build from the Generic Linux (Architecture Independent), Compressed TAR Archive your default data directory is /usr/local/mysql/data which conflicts with the /etc/my.cnf already present which defines datadir=/var/lib/mysql. Also the pid-file defined in the same file does not have permissions for the mysql user/group to write to it in /var/run/mysqld.

A quick remedy is to mv /etc/my.cnf /etc/my.cnf.old which should get your generic source procedure working.

Of course the experience is different of you use the source RPMs.

Another solution, based on scroll listener. Initial conditions are the same as in Sevastyan answer

RecyclerView recyclerView;
TextView tvTitle; //sticky header view

//... onCreate, initialize, etc...

public void bindList(List<Item> items) { //All data in adapter. Item - just interface for different item types
    adapter = new YourAdapter(items);
    recyclerView.setAdapter(adapter);
    StickyHeaderViewManager<HeaderItem> stickyHeaderViewManager = new StickyHeaderViewManager<>(
            tvTitle,
            recyclerView,
            HeaderItem.class, //HeaderItem - subclass of Item, used to detect headers in list
            data -> { // bind function for sticky header view
                tvTitle.setText(data.getTitle());
            });
    stickyHeaderViewManager.attach(items);
}

Layout for ViewHolder and sticky header.

item_header.xml

<TextView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/tv_title"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"/>

Layout for RecyclerView

<FrameLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <android.support.v7.widget.RecyclerView
        android:id="@+id/recycler_view"
        android:layout_width="match_parent"
        android:layout_height="match_parent"/>

    <!--it can be any view, but order important, draw over recyclerView-->
    <include
        layout="@layout/item_header"/>

</FrameLayout>

Class for HeaderItem.

public class HeaderItem implements Item {

    private String title;

    public HeaderItem(String title) {
        this.title = title;
    }

    public String getTitle() {
        return title;
    }

}

It's all use. The implementation of the adapter, ViewHolder and other things, is not interesting for us.

Interface for bind header view.

public interface StickyHeaderViewWrapper<T> {

    void bindView(T data);
}

$('#mytable tr').each(function() {
  // need this to skip the first row
  if ($(this).find("td:first").length > 0) {
    var cutomerId = $(this).find("td:first").html();
  }
});

What about using idate()? idate()

$integer = idate('w', $timestamp);

There is a simple one-liner solution not yet mentioned that will convert hex strings into byte arrays (we don't care about negative interpretation here as it does not matter):

BigInteger.Parse(str, System.Globalization.NumberStyles.HexNumber).ToByteArray().Reverse().ToArray();

If you are

• trying to communicate between two containers from different docker-compose projects and don't want to use the same network (because let's say they would have PostgreSQL or Redis container on the same port and you would prefer to not changing these ports and not use it at the same network)
• developing locally and want to imitate communication between two docker compose projects
• running two docker-compose projects on localhost
• developing especially Django apps or Django Rest Framework (drf) API and running app inside container on some exposed port
• getting Connection refused while trying to communicate between two containers

And you want to

• container api_a communicate to api_b (or vice versa) without the same "docker network"

(example below)

you can use "host" of the second container as IP of your computer and port that is mapped from inside Docker container. You can obtain IP of your computer with this script (from: Finding local IP addresses using Python's stdlib):

import socket
def get_ip():
    s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
    try:
        # doesn't even have to be reachable
        s.connect(('10.255.255.255', 1))
        IP = s.getsockname()[0]
    except:
        IP = '127.0.0.1'
    finally:
        s.close()
    return IP

Example:

project_api_a/docker-compose.yml:

networks:
  app-tier:
    driver: bridge

services:
  api:
    container_name: api_a
    image: api_a:latest
    depends_on:
      - postgresql
    networks:
      - app-tier

inside api_a container you are running Django app: manage.py runserver 0.0.0.0:8000

and second docker-compose.yml from other project:

project_api_b/docker-compose-yml :

networks:
  app-tier:
    driver: bridge

services:
  api:
    container_name: api_b
    image: api_b:latest
    depends_on:
      - postgresql
    networks:
      - app-tier

inside api_b container you are running Django app: manage.py runserver 0.0.0.0:8001

And trying to connect from container api_a to api_b then URL of api_b container will be: http://<get_ip_from_script_above>:8001/

It can be especially valuable if you are using even more than two(three or more) docker-compose projects and it's hard to provide common network for all of it - it's good workaround and solution

According to the UI dialog documentation, the dialog plugin generates something like this:

<div class="ui-dialog ui-widget ui-widget-content ui-corner-all ui-draggable ui-resizable">
   <div class="ui-dialog-titlebar ui-widget-header ui-corner-all ui-helper-clearfix">
      <span id="ui-dialog-title-dialog" class="ui-dialog-title">Dialog title</span>
      <a class="ui-dialog-titlebar-close ui-corner-all" href="#"><span class="ui-icon ui-icon-closethick">close</span></a>
   </div>
   <div class="ui-dialog-content ui-widget-content" id="dialog_style1">
      <p>One content</p>
   </div>
</div>

That means what you can add to any class to exactly to first or second dialog using jQuery's closest() method. For example:

$('#dialog_style1').closest('.ui-dialog').addClass('dialog_style1');

$('#dialog_style2').closest('.ui-dialog').addClass('dialog_style2');

and then CSS it.

Well, it's clearly not a number since it has dashes in it. The error message and the two comments tell you that it is a factor but the commentators are apparently waiting and letting the message sink in. Dirk is suggesting that you do this:

 EPL2011_12$Date2 <- as.Date( as.character(EPL2011_12$Date), "%d-%m-%y")

After that you can do this:

 EPL2011_12FirstHalf <- subset(EPL2011_12, Date2 > as.Date("2012-01-13") )

R date functions assume the format is either "YYYY-MM-DD" or "YYYY/MM/DD". You do need to compare like classes: date to date, or character to character.

When you're on Windows but running VS Code in Windows Subsystem for Linux like this

linux@user: /home$ code .

you actually want to install NodeJs on Linux with

linux@user: /home$ sudo apt install nodejs

Installing NodeJs on Windows, modifying PATH and restarting will get you no results.

Only update your import.

import android.app.AlertDialog;

to

import android.support.v7.app.AlertDialog;

It will be fixed.

document.getElementById("txtBillingGroupName").value = groupName;

You don't need any javascript, you just need your href to be coded like this:

<a href="mailto:[email protected]">email me here!</a>

If the above ans doesn't work then try running conda install ipykernel in new env and then run jupyter notebook from any env, you will be able to see or switch between those kernels.

You can get the name set, save it as a list, and then do your bulk renaming on the string. A good example of this is when you are doing a long to wide transition on a dataset:

names(labWide)
      Lab1    Lab10    Lab11    Lab12    Lab13    Lab14    Lab15    Lab16
1 35.75366 22.79493 30.32075 34.25637 30.66477 32.04059 24.46663 22.53063

nameVec <- names(labWide)
nameVec <- gsub("Lab","LabLat",nameVec)

names(labWide) <- nameVec
"LabLat1"  "LabLat10" "LabLat11" "LabLat12" "LabLat13" "LabLat14""LabLat15"    "LabLat16" " 

With this method you can upper the first char of every word.

Example "HeLlo wOrld" => "Hello World"

public static string FirstCharToUpper(string input)
{
    if (String.IsNullOrEmpty(input))
        throw new ArgumentException("Error");
    return string.Join(" ", input.Split(' ').Select(d => d.First().ToString().ToUpper() +  d.ToLower().Substring(1)));
}

Look at your function s definition. If you forget using "()" after function declaration somewhere, you ll get plenty of errors with the same format:

 ... ??: class, interface, or enum expected ...

And also you have forgot closing bracket after your class or function definition ends. But note that these missing bracket, is not the only reason for this type of error.

Accepted answer is outdated.

If you use MySQL 5.5.3+, use utf8mb4_unicode_ci instead of utf8_unicode_ci to ensure the characters typed by your users won't give you errors.

utf8mb4 supports emojis for example, whereas utf8 might give you hundreds of encoding-related bugs like:

Incorrect string value: ‘\xF0\x9F\x98\x81…’ for column ‘data’ at row 1

Assuming your DateColumn formatted 3312018.0 should be converted to 03/31/2018 as a string. And, some records are missing or 0.

df['DateColumn'] = df['DateColumn'].astype(int)
df['DateColumn'] = df['DateColumn'].astype(str)
df['DateColumn'] = df['DateColumn'].apply(lambda x: x.zfill(8))
df.loc[df['DateColumn'] == '00000000','DateColumn'] = '01011980'
df['DateColumn'] = pd.to_datetime(df['DateColumn'], format="%m%d%Y")
df['DateColumn'] = df['DateColumn'].apply(lambda x: x.strftime('%m/%d/%Y'))

In case you need ViewPager that adjust its size to every child, not just to biggest one, I have wrote a piece of code that does it. Note that there is no animation upon that change (not neccessary in my case)

android:minHeight flag is also supported.

public class ChildWrappingAdjustableViewPager extends ViewPager {
    List<Integer> childHeights = new ArrayList<>(getChildCount());
    int minHeight = 0;
    int currentPos = 0;

    public ChildWrappingAdjustableViewPager(@NonNull Context context) {
        super(context);
        setOnPageChangeListener();
    }

    public ChildWrappingAdjustableViewPager(@NonNull Context context, @Nullable AttributeSet attrs) {
        super(context, attrs);
        obtainMinHeightAttribute(context, attrs);
        setOnPageChangeListener();
    }

    @Override
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {            
        childHeights.clear();

        //calculate child views
        for (int i = 0; i < getChildCount(); i++) {
            View child = getChildAt(i);
            child.measure(widthMeasureSpec, MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED));
            int h = child.getMeasuredHeight();
            if (h < minHeight) {
                h = minHeight;
            }
            childHeights.add(i, h);
        }

        if (childHeights.size() - 1 >= currentPos) {
            heightMeasureSpec = MeasureSpec.makeMeasureSpec(childHeights.get(currentPos), MeasureSpec.EXACTLY);
        }
        super.onMeasure(widthMeasureSpec, heightMeasureSpec);
    }

    private void obtainMinHeightAttribute(@NonNull Context context, @Nullable AttributeSet attrs) {
        int[] heightAttr = new int[]{android.R.attr.minHeight};
        TypedArray typedArray = context.obtainStyledAttributes(attrs, heightAttr);
        minHeight = typedArray.getDimensionPixelOffset(0, -666);
        typedArray.recycle();
    }

    private void setOnPageChangeListener() {
        this.addOnPageChangeListener(new SimpleOnPageChangeListener() {
            @Override
            public void onPageSelected(int position) {
                currentPos = position;

                ViewGroup.LayoutParams layoutParams = ChildWrappingAdjustableViewPager.this.getLayoutParams();
                layoutParams.height = childHeights.get(position);
                ChildWrappingAdjustableViewPager.this.setLayoutParams(layoutParams);
                ChildWrappingAdjustableViewPager.this.invalidate();
            }
        });
    }
}

Have you checked the docstring of write()? It says:

write(str) -> None. Write string str to file.

Note that due to buffering, flush() or close() may be needed before the file on disk reflects the data written.

So you need to convert y to str first.

Also note that the string will be written at the current position which will be at the end of the file, because you'll already have read the old value. Use f.seek(0) to get to the beginning of the file.`

Edit: As for the IOError, this issue seems related. A cite from there:

For the modes where both read and writing (or appending) are allowed (those which include a "+" sign), the stream should be flushed (fflush) or repositioned (fseek, fsetpos, rewind) between either a reading operation followed by a writing operation or a writing operation followed by a reading operation.

So, I suggest you try f.seek(0) and maybe the problem goes away.

Others have very well described the difference between First() and FirstOrDefault(). I want to take a further step in interpreting the semantics of these methods. In my opinion FirstOrDefault is being overused a lot. In the majority of the cases when you’re filtering data you would either expect to get back a collection of elements matching the logical condition or a single unique element by its unique identifier – such as a user, book, post etc... That’s why we can even get as far as saying that FirstOrDefault() is a code smell not because there is something wrong with it but because it’s being used way too often. This blog post explores the topic in details. IMO most of the times SingleOrDefault() is a much better alternative so watch out for this mistake and make sure you use the most appropriate method that clearly represents your contract and expectations.

Rahul's answer is best fit for your question. Anyway, if you have a group of checkboxes to be checked and not all the checkbox in your form, you can go for it.

Put a classname for all the checkboxes you want to check, say for example, a classname test_check and now you can check if any of the checkbox is checked belonging to the group by:

$("#formID .test_check:checked").length > 0

If it returns true, assume that one or more checkboxes are checked having the classname test_check and none checked if returns false.

Hope it helps someone. Thanks :)-

There are two ideas here being confused:

1. The first idea is about "returning" styles back to a browser's UA style sheet value set (the style sheet that comes with the browser on install that defines what each element looks like). Each browser defines its own styles as to how elements should look by default. This idea is about returning all page styles back to each browsers native element styles.
2. The second idea is about "resetting" all default browser styles to a common look and feel shared by all browsers. People build special "reset" sheets to try and align all the browser elements to a common agreed on style, universally. This has nothing to do with a browsers default UA styles and more about "cleaning up" and aligning all browsers to a common base style. This is an additive process only.

Those are two very different concepts people here are confusing.

Because each browser often had default, out-of-the-box element and layout styles that looked slightly different, people came up with the idea of the "reset" or "reboot" style sheet to align all the browsers BEFORE applying custom CSS. Bootstrap now does this, for example. But that had nothing to do with people wanting to return to the browser's default look and feel.

The problem was not the building of these custom "reset" style sheets, it is figuring out what the default CSS was for each browser and each element BEFORE any styles were applied. Most found out you cant rebuild an existing clean cascade until you "clear out" all styles already applied. But how to get back to the default browser styling?

For some this meant going beyond returning the elements to the browsers UA style sheet that comes with the browser. Many wanted to reset back to "initial" property values which has NOTHING to do with the browser's default style, but really the properties defaults. This is dangerous as in the case of "display" pushes block level elements back to "inline" and breaks table layouts and other things.

So I do NOT agree with users here using "initial" to reset anything or custom reset classes that change every property back to some arbitrary base value set.

A better solution to me has always been to attempt to try and return all core element styling back to the browser's UA style sheet values, which is what all our end-users are using anyway. If you are creating a new website, you don't have to do this. You start with the browser's default styles and add to them. Its only after you've added third-party CSS products, or found yourself with complicated CSS cascades you want to figure out how to return to the browser default style sheet values.

For this reason, I'm for creating your own "reset" sheet to reset all the elements to one common style first that's shared by all old and new browsers as a first step. You then have a solid framework that's much easier to revert to without going back to the browser defaults. You are simply building on a reset common core set of element style values. Once build your own "reset" sheet, one that ADDS not ALTERS the browsers UA styles, you have a site that's very easy to modify.

The only problem remaining then is when you have a site that does NOT have such a reset sheet, or have that complex third party CSS and need to try and return to the browser UA styles. How do you do that?

I realize Internet Explorer has forced us too manually reset every property to get back to any sort of reset. But pushing those property values all back to "initial" destroys the browser UA style sheet values completely! BAD IDEA! A better way is to simply use "all:revert" for non-IE browsers on every element using a wildcard, and "inherit" only for a handful of inherited root-level properties found in the "html" and "body" elements that affect all inheriting children in the page. (see below). I'm NOT for these huge resets of properties using "initial" or going back to some imaginary standard we assume all browsers or IE will use. For starters "initial" has poor support in IE and doesn't reset values to element defaults, only property defaults. But its also pointless if you are going to create a reset sheet to align all elements to a common style. In that case its pointless to clear out styles and start over.

So here is my simple solution that in most cases does enough to reset what text-based values sift down into IE from the root and use "all:revert" for all non-IE browsers to force non-inherited values back to the browser's UA style sheet completely, giving you a true restart. This does not interfere with higher level classes and styles layered over your element styles, which should always be the goal anyway. Its why I'm NOT for these custom reset classes which is tedious and unnecessary and doesn't return the element to its browser UA style anyway. Notice the slightly more selective selectors below which would write over, for example, Bootstrap's "reboot" style values, returning them to the browser default styles. These would not reset element styles on elements for IE, of course, but for non-IE browsers and most inheritable text styling it would return elements in most agents to the UA style sheets that come with browsers:

:root, html {
    display: block;
    font-family: inherit;
    font-size: inherit;
    font-weight: inherit;
    line-height: inherit;
    -webkit-text-size-adjust: inherit;
    -webkit-tap-highlight-color: inherit;
    all: revert;
}

html body {
    display: block;
    font-family: inherit;
    font-size: inherit;
    font-weight: inherit;
    line-height: inherit;
    margin: inherit;
    padding: inherit;
    color: inherit;
    text-align: inherit;
    background-color: inherit;
    background: inherit;
    all: revert;
}

html body * {
    /* IE elements under body would not be affected by this, but if needed you could add custom elements with property resets as needed to this sheet. */
    all: revert;
}

<select name="FakeName" id="Fake-ID" aria-required="true" required>  <?php $options=nl2br(file_get_contents("employees.txt")); $options=explode("<br />",$options);  foreach ($options as $item_array) { echo "<option value='".$item_array"'>".$item_array"</option>";  } ?> </select> 

Variable definitions right:

$      => SCSS, SASS
--     => CSS
@      => LESS

All answers is good but question a little different than answers

"about Sass. How is SCSS different from CSS" : scss is well formed CSS3 syntax. uses sass preprocessor to create that.

and if I use SCSS instead of CSS will it work the same? yes. if your ide supports sass preprocessor. than it will work same.

Sass has two syntaxes. The most commonly used syntax is known as “SCSS” (for “Sassy CSS”), and is a superset of CSS3’s syntax. This means that every valid CSS3 stylesheet is valid SCSS as well. SCSS files use the extension .scss.

The second, older syntax is known as the indented syntax (or just “.sass”). Inspired by Haml’s terseness, it’s intended for people who prefer conciseness over similarity to CSS. Instead of brackets and semicolons, it uses the indentation of lines to specify blocks. Files in the indented syntax use the extension .sass.

What Is A CSS Preprocessor?

CSS in itself is devoid of complex logic and functionality which is required to write reusable and organized code. As a result, a developer is bound by limitations and would face extreme difficulty in code maintenance and scalability, especially when working on large projects involving extensive code and multiple CSS stylesheets. This is where CSS Preprocessors come to the rescue.

A CSS Preprocessor is a tool used to extend the basic functionality of default vanilla CSS through its own scripting language. It helps us to use complex logical syntax like – variables, functions, mixins, code nesting, and inheritance to name a few, supercharging your vanilla CSS. By using CSS Preprocessors, you can seamlessly automate menial tasks, build reusable code snippets, avoid code repetition and bloating and write nested code blocks that are well organized and easy to read. However, browsers can only understand native vanilla CSS code and will be unable to interpret the CSS Preprocessor syntax. Therefore, the complex and advanced Preprocessor syntax needs to be first compiled into native CSS syntax which can then be interpreted by the browsers to avoid cross browser compatibility issues. While different Preprocessors have their own unique syntaxes, eventually all of them are compiled to the same native CSS code.

Moving forward in the article, we will take a look at the 3 most popular CSS Preprocessors currently being used by developers around the world i.e Sass, LESS, and Stylus. Before you decide the winner between Sass vs LESS vs Stylus, let us get to know them in detail first.

Sass – Syntactically Awesome Style Sheets

Sass is the acronym for “Syntactically Awesome Style Sheets”. Sass is not only the most popular CSS Preprocessor in the world but also one of the oldest, launched in 2006 by Hampton Catlin and later developed by Natalie Weizenbaum. Although Sass is written in Ruby language, a Precompiler LibSass allows Sass to be parsed in other languages and decouple it from Ruby. Sass has a massive active community and extensive learning resources available on the net for beginners. Thanks to its maturity, stability and powerful logical prowess, Sass has established itself to the forefront of CSS Preprocessor ahead of its rival peers.

Sass can be written in 2 syntaxes either using Sass or SCSS. What is the difference between the two? Let’s find out.

Syntax Declaration: Sass vs SCSS

• SCSS stands for Sassy CSS. Unlike Sass, SCSS is not based on indentation.
• .sass extension is used as original syntax for Sass, while SCSS offers a newer syntax with .scss extension.
• Unlike Sass, SCSS has curly braces and semicolons, just like CSS.
• Contrary to SCSS, Sass is difficult to read as it is quite deviant from CSS. Which is why SCSS it the more recommended Sass syntax as it is easier to read and closely resembles Native CSS while at the same time enjoying with power of Sass.

Consider the example below with Sass vs SCSS syntax along with Compiled CSS code.

Sass SYNTAX
    $font-color: #fff
    $bg-color: #00f

    #box
      color: $font-color
      background: $bg-color

SCSS SYNTAX
    $font-color: #fff;
    $bg-color: #00f;

    #box{
      color: $font-color;
      background: $bg-color;
    }

In both cases, be it Sass or SCSS, the compiled CSS code will be the same –

#box {
      color: #fff;
      background: #00f;

Usage of Sass

Arguably the most Popular front end framework Bootstrap is written in Sass. Up until version 3, Bootstrap was written in LESS but bootstrap 4 adopted Sass and boosted its popularity. A few of the big companies using Sass are – Zapier, Uber, Airbnb and Kickstarter.

LESS – Leaner Style Sheets

LESS is an acronym for “Leaner Stylesheets”. It was released in 2009 by Alexis Sellier, 3 years after the initial launch of Sass in 2006. While Sass is written in Ruby, LESS is written JavaScript. In fact, LESS is a JavaScript library that extends the functionality of native vanilla CSS with mixins, variables, nesting and rule set loop. Sass vs LESS has been a heated debate. It is no surprise that LESS is the strongest competitor to Sass and has the second-largest user base. However, When bootstrap dumped LESS in favor of Sass with the launch of Bootstrap 4, LESS has waned in popularity. One of the few disadvantages of LESS over Sass is that it does not support functions. Unlike Sass, LESS uses @ to declare variables which might cause confusion with @media and @keyframes. However, One key advantage of LESS over Sass and Stylus or any other preprocessors, is the ease of adding it in your project. You can do that either by using NPM or by incorporating Less.js file. Syntax Declaration: LESS Uses .less extension. Syntax of LESS is quite similar to SCSS with the exception that for declaring variables, instead of $ sign, LESS uses @.

@font-color: #fff;
    @bg-color: #00f

    #box{
      color: @font-color;
      background: @bg-color;
    }

COMPILED CSS
    #box {
        color: #fff;
        background: #00f;
      }

Usage Of LESS The popular Bootstrap framework until the launch of version 4 was written in LESS. However, another popular framework called SEMANTIC UI is still written in LESS. Among the big companies using Sass are – Indiegogo, Patreon, and WeChat

Stylus

The stylus was launched in 2010 by former Node JS developer TJ Holowaychuk, nearly 4 years after the release of Sass and 1 year after the release of LESS. The stylus is written Node JS and fits perfectly with JS stack. The stylus was heavily influenced by the logical prowess of the Sass and simplicity of LESS. Even though Stylus is still popular with Node JS developers, it hasn’t managed to carve out a sizeable share for itself. One advantage of Stylus over Sass or LESS, is that it is armed with extremely powerful built-in functions and is capable of handling heavy computing.

Syntax Declaration: Stylus Uses .styl extension. Stylus offers a great deal of flexibility in writing syntax, supports native CSS as well as allows omission of brackets colons and semicolons. Also, note that Stylus does not use @ or $ symbols for defining variables. Instead, Stylus uses the assignment operators to indicate a variable declaration.

STYLUS SYNTAX WRITTEN LIKE NATIVE CSS

font-color = #fff;
bg-color = #00f;

#box {
    color: font-color;
    background: bg-color;
}

OR

STYLUS SYNTAX WITHOUT CURLY BRACES

font-color = #fff;
bg-color = #00f;

#box 
    color: font-color;
    background: bg-color;

OR

STYLUS SYNTAX WITHOUT COLONS AND SEMICOLONS

font-color = #fff
bg-color = #00f

#box 
    color font-color
    background bg-color

MongoDB actually stores the millis of a date as an int(64), as prescribed by http://bsonspec.org/#/specification

However, it can get pretty confusing when you retrieve dates as the client driver will instantiate a date object with its own local timezone. The JavaScript driver in the mongo console will certainly do this.

So, if you care about your timezones, then make sure you know what it's supposed to be when you get it back. This shouldn't matter so much for the queries, as it will still equate to the same int(64), regardless of what timezone your date object is in (I hope). But I'd definitely make queries with actual date objects (not strings) and let the driver do its thing.

This is a mistake:

m.check(side);

That code has to go inside a function. Your class definition can only contain declarations and functions.

Classes don't "run", they provide a blueprint for how to make an object.

The line Message m; means that an Orderbook will contain Message called m, if you later create an Orderbook.

I have been working on a system that ran on a PC and Mac and was battling to find code that worked for inserting pictures on both PC and Mac. This worked for me so hopefully someone else can make use of it!

Note: the strPictureFilePath and strPictureFileName variables need to be set to valid PC and Mac paths Eg

For PC: strPictureFilePath = "E:\Dropbox\" and strPictureFileName = "TestImage.jpg" and with Mac: strPictureFilePath = "Macintosh HD:Dropbox:" and strPictureFileName = "TestImage.jpg"

Code as Follows:

    On Error GoTo ErrorOccured

    shtRecipeBrowser.Cells(intDestinationRecipeRowCount, 1).Select

    ActiveSheet.Pictures.Insert(Trim(strPictureFilePath & strPictureFileName)).Select

    Selection.ShapeRange.Left = shtRecipeBrowser.Cells(intDestinationRecipeRowCount, 1).Left
    Selection.ShapeRange.Top = shtRecipeBrowser.Cells(intDestinationRecipeRowCount, 1).Top + 10
    Selection.ShapeRange.LockAspectRatio = msoTrue
    Selection.ShapeRange.Height = 130

Perhaps I am missing something, but although the other solutions do call the parent scope function there is no ability to pass arguments from directive code, this is because the update-fn is calling updateFn() with fixed parameters, in for example {msg: "Hello World"}. A slight change allows the directive to pass arguments, which I would think is far more useful.

<test color1="color1" update-fn="updateFn"></test>

Note the HTML is passing a function reference, i.e., without () brackets.

JS

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

app.controller("testCtrl", function($scope) {
    $scope.color1 = "color";
    $scope.updateFn = function(msg) {        
        alert(msg);
    }
});

app.directive('test', function() {
    return {
        restrict: 'E',
        scope: {
            color1: '=',
            updateFn: '&'
        },
        // object is passed while making the call
        template: "<button ng-click='callUpdate()'>
            Click</button>",
        replace: true,        
        link: function(scope, elm, attrs) {       
          scope.callUpdate = function() {
            scope.updateFn()("Directive Args");
          }
        }
    }
});

So in the above, the HTML is calling local scope callUpdate function, which then 'fetches' the updateFn from the parent scope and calls the returned function with parameters that the directive can generate.

All the other responses I see are fine, but C# has support for named groups!

I'd use the following code:

const string input = "Lorem ipsum dolor sit %download%#456 amet, consectetur adipiscing %download%#3434 elit. Duis non nunc nec mauris feugiat porttitor. Sed tincidunt blandit dui a viverra%download%#298. Aenean dapibus nisl %download%#893434 id nibh auctor vel tempor velit blandit.";

static void Main(string[] args)
{
    Regex expression = new Regex(@"%download%#(?<Identifier>[0-9]*)");
    var results = expression.Matches(input);
    foreach (Match match in results)
    {
        Console.WriteLine(match.Groups["Identifier"].Value);
    }
}

The code that reads: (?<Identifier>[0-9]*) specifies that [0-9]*'s results will be part of a named group that we index as above: match.Groups["Identifier"].Value

It is not entirely clear what you want, but I would use numpy.random.randint:

import numpy.random as nprnd
import timeit

t1 = timeit.Timer('[random.randint(0, 1000) for r in xrange(10000)]', 'import random') # v1

### Change v2 so that it picks numbers in (0, 10000) and thus runs...
t2 = timeit.Timer('random.sample(range(10000), 10000)', 'import random') # v2
t3 = timeit.Timer('nprnd.randint(1000, size=10000)', 'import numpy.random as nprnd') # v3

print t1.timeit(1000)/1000
print t2.timeit(1000)/1000
print t3.timeit(1000)/1000

which gives on my machine:

0.0233682730198
0.00781716918945
0.000147947072983

Note that randint is very different from random.sample (in order for it to work in your case I had to change the 1,000 to 10,000 as one of the commentators pointed out -- if you really want them from 0 to 1,000 you could divide by 10).

And if you really don't care what distribution you are getting then it is possible that you either don't understand your problem very well, or random numbers -- with apologies if that sounds rude...

Addition to what Albert has already said:

This code (a mashup of various samples) provides the ability to have a SaveAs dialog box

Function getFileName() As String
    Dim fDialog    As Object
    Set fDialog = Application.FileDialog(msoFileDialogSaveAs)
    Dim varFile As Variant

    With fDialog
       .AllowMultiSelect = False
       .Title = "Select File Location to Export XLSx :"
       .InitialFileName = "jeffatwood.xlsx"

    If .Show = True Then
       For Each varFile In .SelectedItems
         getFileName = varFile
       Next
    End If
End With
End Function

First of all, I suggest to modify a bit your sql query:

 select * from shift 
 where shift.shiftid not in (select employeeshift.shiftid from employeeshift 
                             where employeeshift.empid = 57);

This query provides same functionality. If you want to get the same result with LINQ, you can try this code:

//Variable dc has DataContext type here
//Here we get list of ShiftIDs from employeeshift table
List<int> empShiftIds = dc.employeeshift.Where(p => p.EmpID = 57).Select(s => s.ShiftID).ToList();

//Here we get the list of our shifts
List<shift> shifts = dc.shift.Where(p => !empShiftIds.Contains(p.ShiftId)).ToList();

I think random.choice() is a better option.

import numpy as np

mylist = [13,23,14,52,6,23]

np.random.choice(mylist, 3, replace=False)

the function returns an array of 3 randomly chosen values from the list

I also use Stefan Petre’s http://www.eyecon.ro/bootstrap-datepicker and it does not work with Bootstrap 3 without modification. Note that http://eternicode.github.io/bootstrap-datepicker/ is a fork of Stefan Petre's code.

You have to change your markup (the sample markup will not work) to use the new CSS and form grid layout in Bootstrap 3. Also, you have to modify some CSS and JavaScript in the actual bootstrap-datepicker implementation.

Here is my solution:

<div class="form-group row">
  <div class="col-xs-8">
    <label class="control-label">My Label</label>
    <div class="input-group date" id="dp3" data-date="12-02-2012" data-date-format="mm-dd-yyyy">
      <input class="form-control" type="text" readonly="" value="12-02-2012">
      <span class="input-group-addon"><i class="glyphicon glyphicon-calendar"></i></span>
    </div>
  </div>
</div>

CSS changes in datepicker.css on lines 176-177:

.input-group.date .input-group-addon i,
.input-group.date .input-group-addon i {

Javascript change in datepicker-bootstrap.js on line 34:

this.component = this.element.is('.date') ? this.element.find('.input-group-addon') : false;

UPDATE

Using the newer code from http://eternicode.github.io/bootstrap-datepicker/ the changes are as follows:

CSS changes in datepicker.css on lines 446-447:

.input-group.date .input-group-addon i,
.input-group.date .input-group-addon i {

Javascript change in datepicker-bootstrap.js on line 46:

 this.component = this.element.is('.date') ? this.element.find('.input-group-addon, .btn') : false;

Finally, the JavaScript to enable the datepicker (with some options):

 $(".input-group.date").datepicker({ autoclose: true, todayHighlight: true });

Tested with Bootstrap 3.0 and JQuery 1.9.1. Note that this fork is better to use than the other as it is more feature rich, has localization support and auto-positions the datepicker based on the control position and window size, avoiding the picker going off the screen which was a problem with the older version.

You start tomcat from some directory - which is the $cwd for tomcat. You can specify any path relative to this $cwd.

suppose you have

home
- tomcat
 |_bin
- cssStore
 |_file.css

And suppose you start tomcat from ~/tomcat, using the command "bin/startup.sh".

~/tomcat becomes the home directory ($cwd) for tomcat

You can access "../cssStore/file.css" from class files in your servlet now

Hope that helps, - M.S.

When you create an App, a file called styles.xml will be created in your res/values folder. If you change the styles, you can change the background, text color, etc for all your layouts. That way you don’t have to go into each individual layout and change the it manually.

styles.xml:

<resources xmlns:android="http://schemas.android.com/apk/res/android">
<style name="Theme.AppBaseTheme" parent="@android:style/Theme.Light">
    <item name="android:editTextColor">#295055</item> 
    <item name="android:textColorPrimary">#295055</item>
    <item name="android:textColorSecondary">#295055</item>
    <item name="android:textColorTertiary">#295055</item>
    <item name="android:textColorPrimaryInverse">#295055</item>
    <item name="android:textColorSecondaryInverse">#295055</item>
    <item name="android:textColorTertiaryInverse">#295055</item>

     <item name="android:windowBackground">@drawable/custom_background</item>        
</style>

<!-- Application theme. -->
<style name="AppTheme" parent="AppBaseTheme">
    <!-- All customizations that are NOT specific to a particular API-level can go here. -->
</style>

parent="@android:style/Theme.Light" is Google’s native colors. Here is a reference of what the native styles are: https://android.googlesource.com/platform/frameworks/base/+/refs/heads/master/core/res/res/values/themes.xml

The default Android style is also called “Theme”. So you calling it Theme probably confused the program.

name="Theme.AppBaseTheme" means that you are creating a style that inherits all the styles from parent="@android:style/Theme.Light". This part you can ignore unless you want to inherit from AppBaseTheme again. = <style name="AppTheme" parent="AppBaseTheme">

@drawable/custom_background is a custom image I put in the drawable’s folder. It is a 300x300 png image.

#295055 is a dark blue color.

My code changes the background and text color. For Button text, please look through Google’s native stlyes (the link I gave u above).

Then in Android Manifest, remember to include the code:

<application
android:theme="@style/Theme.AppBaseTheme">

I don't know of any full Chrome component, but you could use WebKit, which is the rendering engine that Chrome uses. The Mono project made WebKit Sharp, which might work for you.

Previous answers cover about ASCII character at a certain index.

It is a little bit troublesome to get a Unicode character at a certain index in Python 2.

E.g., with s = '????????' which is <type 'str'>,

__getitem__, e.g., s[i] , does not lead you to where you desire. It will spit out semething like ?. (Many Unicode characters are more than 1 byte but __getitem__ in Python 2 is incremented by 1 byte.)

In this Python 2 case, you can solve the problem by decoding:

s = '????????'
s = s.decode('utf-8')
for i in range(len(s)):
    print s[i]

After a lot of digging around I finally ended up downloading the source code of the recovery section of Android. Turns out you can actually send commands to the recovery.

 * The arguments which may be supplied in the recovery.command file:
 *   --send_intent=anystring - write the text out to recovery.intent
 *   --update_package=path - verify install an OTA package file
 *   --wipe_data - erase user data (and cache), then reboot
 *   --wipe_cache - wipe cache (but not user data), then reboot
 *   --set_encrypted_filesystem=on|off - enables / diasables encrypted fs

Those are the commands you can use according to the one I found but that might be different for modded files. So using adb you can do this:

adb shell
recovery --wipe_data

Using --wipe_data seemed to do what I was looking for which was handy although I have not fully tested this as of yet.

EDIT:

For anyone still using this topic, these commands may change based on which recovery you are using. If you are using Clockword recovery, these commands should still work. You can find other commands in /cache/recovery/command

For more information please see here: https://github.com/CyanogenMod/android_bootable_recovery/blob/cm-10.2/recovery.c

Isn't this the normal way to free the memory associated with an object?

This is a common way of managing dynamically allocated memory, but it's not a good way to do so. This sort of code is brittle because it is not exception-safe: if an exception is thrown between when you create the object and when you delete it, you will leak that object.

It is far better to use a smart pointer container, which you can use to get scope-bound resource management (it's more commonly called resource acquisition is initialization, or RAII).

As an example of automatic resource management:

void test()
{
    std::auto_ptr<Object1> obj1(new Object1);

} // The object is automatically deleted when the scope ends.

Depending on your use case, auto_ptr might not provide the semantics you need. In that case, you can consider using shared_ptr.

As for why your program crashes when you delete the object, you have not given sufficient code for anyone to be able to answer that question with any certainty.

Unless you have a special situation that requires a non thread-pool thread, just use a thread pool thread like this:

Action secondFooAsync = new Action(SecondFoo);

secondFooAsync.BeginInvoke(new AsyncCallback(result =>
      {
         (result.AsyncState as Action).EndInvoke(result); 

      }), secondFooAsync); 

Gaurantees that EndInvoke is called to take care of the clean up for you.

I think you should store the size somewhere.

The null-terminated-string kind of model for determining array length is a bad idea. For instance, getting the size of the array will be O(N) when it could very easily have been O(1) otherwise.

Having that said, a good solution might be glib's Arrays, they have the added advantage of expanding automatically if you need to add more items.

P.S. to be completely honest, I haven't used much of glib, but I think it's a (very) reputable library.

Here I found a workaround to pass multiple generic objects (as json) from jquery to a WEB API using JObject, and then cast back to your required specific object type in api controller. This objects provides a concrete type specifically designed for working with JSON.

var combinedObj = {}; 
combinedObj["obj1"] = [your json object 1]; 
combinedObj["obj2"] = [your json object 2];

$http({
       method: 'POST',
       url: 'api/PostGenericObjects/',
       data: JSON.stringify(combinedObj)
    }).then(function successCallback(response) {
         // this callback will be called asynchronously
         // when the response is available
         alert("Saved Successfully !!!");
    }, function errorCallback(response) {
         // called asynchronously if an error occurs
         // or server returns response with an error status.
         alert("Error : " + response.data.ExceptionMessage);
});

and then you can get this object in your controller

using Newtonsoft.Json;
using Newtonsoft.Json.Linq;

public [OBJECT] PostGenericObjects(object obj)
    {
        string[] str = GeneralMethods.UnWrapObjects(obj);
        var item1 = JsonConvert.DeserializeObject<ObjectType1>(str[0]);
        var item2 = JsonConvert.DeserializeObject<ObjectType2>(str[1]);

        return *something*;
    } 

I have made a generic function to unwrap the complex object, so there is no limitation of number of objects while sending and unwrapping. We can even send more than two objects

public class GeneralMethods
{
    public static string[] UnWrapObjects(object obj)
    {
        JObject o = JObject.Parse(obj.ToString());

        string[] str = new string[o.Count];

        for (int i = 0; i < o.Count; i++)
        {
            string var = "obj" + (i + 1).ToString();
            str[i] = o[var].ToString(); 
        }

        return str;
    }

}

I have posted the solution to my blog with a little more description with simpler code to integrate easily.

Pass multiple complex objects to Web API

I hope it would help someone. I would be interested to hear from the experts here regarding the pros and cons of using this methodology.

Yes if you are using latest java which is version 8. Java8 make it possible to define anonymous functions which was impossible in previous versions.

Lets take example from java docs to get know how we can declare anonymous functions, classes

The following example, HelloWorldAnonymousClasses, uses anonymous classes in the initialization statements of the local variables frenchGreeting and spanishGreeting, but uses a local class for the initialization of the variable englishGreeting:

public class HelloWorldAnonymousClasses {

    interface HelloWorld {
        public void greet();
        public void greetSomeone(String someone);
    }

    public void sayHello() {

        class EnglishGreeting implements HelloWorld {
            String name = "world";
            public void greet() {
                greetSomeone("world");
            }
            public void greetSomeone(String someone) {
                name = someone;
                System.out.println("Hello " + name);
            }
        }

        HelloWorld englishGreeting = new EnglishGreeting();

        HelloWorld frenchGreeting = new HelloWorld() {
            String name = "tout le monde";
            public void greet() {
                greetSomeone("tout le monde");
            }
            public void greetSomeone(String someone) {
                name = someone;
                System.out.println("Salut " + name);
            }
        };

        HelloWorld spanishGreeting = new HelloWorld() {
            String name = "mundo";
            public void greet() {
                greetSomeone("mundo");
            }
            public void greetSomeone(String someone) {
                name = someone;
                System.out.println("Hola, " + name);
            }
        };
        englishGreeting.greet();
        frenchGreeting.greetSomeone("Fred");
        spanishGreeting.greet();
    }

    public static void main(String... args) {
        HelloWorldAnonymousClasses myApp =
            new HelloWorldAnonymousClasses();
        myApp.sayHello();
    }            
}

Syntax of Anonymous Classes

Consider the instantiation of the frenchGreeting object:

    HelloWorld frenchGreeting = new HelloWorld() {
        String name = "tout le monde";
        public void greet() {
            greetSomeone("tout le monde");
        }
        public void greetSomeone(String someone) {
            name = someone;
            System.out.println("Salut " + name);
        }
    };

The anonymous class expression consists of the following:

• The new operator

• The name of an interface to implement or a class to extend. In this example, the anonymous class is implementing the interface HelloWorld.

• Parentheses that contain the arguments to a constructor, just like a normal class instance creation expression. Note: When you implement an interface, there is no constructor, so you use an empty pair of parentheses, as in this example.

• A body, which is a class declaration body. More specifically, in the body, method declarations are allowed but statements are not.

This will also checks in leap year. This is pure regex, so it's faster than any lib (also faster than moment.js). But if you gonna use a lot of dates in ur code, I do recommend to use moment.js

var dateRegex = /^(?=\d)(?:(?:31(?!.(?:0?[2469]|11))|(?:30|29)(?!.0?2)|29(?=.0?2.(?:(?:(?:1[6-9]|[2-9]\d)?(?:0[48]|[2468][048]|[13579][26])|(?:(?:16|[2468][048]|[3579][26])00)))(?:\x20|$))|(?:2[0-8]|1\d|0?[1-9]))([-.\/])(?:1[012]|0?[1-9])\1(?:1[6-9]|[2-9]\d)?\d\d(?:(?=\x20\d)\x20|$))?(((0?[1-9]|1[012])(:[0-5]\d){0,2}(\x20[AP]M))|([01]\d|2[0-3])(:[0-5]\d){1,2})?$/;

console.log(dateRegex.test('21/01/1986'));

Official FAQ ( https://reactjs.org/docs/hooks-faq.html#is-there-something-like-forceupdate ) now recommends this way if you really need to do it:

  const [ignored, forceUpdate] = useReducer(x => x + 1, 0);

  function handleClick() {
    forceUpdate();
  }

sed -n '2p' < file.txt

will print 2nd line

sed -n '2011p' < file.txt

2011th line

sed -n '10,33p' < file.txt

line 10 up to line 33

sed -n '1p;3p' < file.txt

1st and 3th line

and so on...

For adding lines with sed, you can check this:

sed: insert a line in a certain position

If using MacPorts on OS X 10.9 Mavericks, you can simply do:

sudo port install maven3
sudo port select --set maven maven3

You are using an adjacent sibling selector (+) when the elements are not siblings. The label is the parent of the input, not it's sibling.

CSS has no way to select an element based on it's descendents (nor anything that follows it).

You'll need to look to JavaScript to solve this.

Alternatively, rearrange your markup:

<input id="foo"><label for="foo">…</label>

If you want to reuse in multiple places:

var maxHeight = function(elems){
    return Math.max.apply(null, elems.map(function ()
    {
        return $(this).height();
    }).get());
}

Then you can use:

maxHeight($("some selector"));

You can use pandas.Series.map :

df['col'].map('str{}'.format)

It will apply the word "str" before all your values.

I don't know what things were like in the alpha, but I'm using beta 12 right now and this works fine. If you have an array of objects, create a select like this:

<select [(ngModel)]="simpleValue"> // value is a string or number
    <option *ngFor="let obj of objArray" [value]="obj.value">{{obj.name}}</option>
</select>

If you want to match on the actual object, I'd do it like this:

<select [(ngModel)]="objValue"> // value is an object
    <option *ngFor="let obj of objArray" [ngValue]="obj">{{obj.name}}</option>
</select>

If you are 100% sure $message contain ISO-8859-1 you can use utf8_encode as David says. Otherwise use mb_detect_encoding and mb_convert_encoding on $message.

Also take note that

$mail -> charSet = "UTF-8"; 

Should be replaced by:

$mail->CharSet = 'UTF-8';

And placed after the instantiation of the class (after the new). The properties are case sensitive! See the PHPMailer doc fot the list & exact spelling.

Also the default encoding of PHPMailer is 8bit which can be problematic with UTF-8 data. To fix this you can do:

$mail->Encoding = 'base64';

Take note that 'quoted-printable' would probably work too in these cases (and maybe even 'binary'). For more details you can read RFC1341 - Content-Transfer-Encoding Header Field.

To avoid getting the warning in a push navigation, you can directly use :

[self.view.window.rootViewController presentViewController:viewController animated:YES completion:nil];

And then in your modal view controller, when everything is finished, you can just call :

[self dismissViewControllerAnimated:YES completion:nil];

For converting number as varchar to int, you could also use simple

(column + 0)

Use services.msc or (Start > Control Panel > Administrative Tools > Services) to find the service in question. Double-click to see the service name and the path to the executable.

Check the exe version information for a clue as to the owner of the service, and use Add/Remove programs to do a clean uninstall if possible.

Failing that, from the command prompt:

sc stop servicexyz
sc delete servicexyz

No restart should be required.

The size_t type is the unsigned integer type that is the result of the sizeof operator (and the offsetof operator), so it is guaranteed to be big enough to contain the size of the biggest object your system can handle (e.g., a static array of 8Gb).

The size_t type may be bigger than, equal to, or smaller than an unsigned int, and your compiler might make assumptions about it for optimization.

You may find more precise information in the C99 standard, section 7.17, a draft of which is available on the Internet in pdf format, or in the C11 standard, section 7.19, also available as a pdf draft.

FETCH_HEAD is a short-lived ref, to keep track of what has just been fetched from the remote repository. git pull first invokes git fetch, in normal cases fetching a branch from the remote; FETCH_HEAD points to the tip of this branch (it stores the SHA1 of the commit, just as branches do). git pull then invokes git merge, merging FETCH_HEAD into the current branch.

The result is exactly what you'd expect: the commit at the tip of the appropriate remote branch is merged into the commit at the tip of your current branch.

This is a bit like doing git fetch without arguments (or git remote update), updating all your remote branches, then running git merge origin/<branch>, but using FETCH_HEAD internally instead to refer to whatever single ref was fetched, instead of needing to name things.

t indicates for text mode

https://docs.python.org/release/3.1.5/library/functions.html#open

on linux, there's no difference between text mode and binary mode, however, in windows, they converts \n to \r\n when text mode.

In my case, after 30 minutes changing permissions, got into account that the XLSX file I was trying to transfer was still open in Excel.

In some references, use the second instead of the first:

soup_object= BeautifulSoup(markup,'html-parser')
soup_object= BeautifulSoup(markup,'html.parser')

With native JavaScript:

newelement = element.cloneNode(bool)

where the Boolean indicates whether to clone child nodes or not.

Here is the complete documentation on MDN.

In my case there was a static variable which was not initialized. When I initialized it, the error was removed. I don't know the logic behind it but worked for me. I know its a little late but other people with similar problem might get some help.

If you are using Bootstrap Responsive Utilities or similar alternative that allows to hide / show divs depending on the break points, it may be possible to use several elements and show the most appropriate. i.e.

It may have been because I am still new to VS and definitely new to C, but the only thing that allowed me to build was adding

#pragma warning(disable:4996)

At the top of my file, this suppressed the C4996 error I was getting with sprintf

A bit annoying but perfect for my tiny bit of code and by far the easiest.

I read about it here: https://msdn.microsoft.com/en-us/library/2c8f766e.aspx

IMO the best way to check if an array contains a given value is to use System.Collections.Generic.IList<T>.Contains(T item) method the following way:

((IList<string>)stringArray).Contains(value)

Complete code sample:

string[] stringArray = { "text1", "text2", "text3", "text4" };
string value = "text3";
if (((IList<string>)stringArray).Contains(value)) Console.WriteLine("The array contains "+value);
else Console.WriteLine("The given string was not found in array.");

T[] arrays privately implement a few methods of List<T>, such as Count and Contains. Because it's an explicit (private) implementation, you won't be able to use these methods without casting the array first. This doesn't only work for strings - you can use this trick to check if an array of any type contains any element, as long as the element's class implements IComparable.

Keep in mind not all IList<T> methods work this way. Trying to use IList<T>'s Add method on an array will fail.

Start MySQL Workbench, then Server -> Options File and look at bottom of the window; it will say something like "Configuration File: C:\ProgramData\MySQL\MySQL Server 5.6\my.ini"

ObjectMapper.readTree() can do this in one line:

mapper.readTree(json).toPrettyString();

Since readTree produces a JsonNode, this should pretty much always produce equivalent pretty-formatted JSON, as it JsonNode is a direct tree representation of the underlying JSON string.

Prior to Jackson 2.10

The JsonNode.toPrettyString() method was added in Jackson 2.10. Prior to that, a second call to the ObjectMapper was needed to write the pretty formatted result:

mapper.writerWithDefaultPrettyPrinter()
        .writeValueAsString(mapper.readTree(json));

I was attempting to do something similar to this, but I needed the results ordered by date since I can't rely on the ID field as a sortable column. Here's the solution I came up with.

First we find out the index of the desired record in the table, when it's sorted as we want:

SELECT row
FROM 
(SELECT @rownum:=@rownum+1 row, a.* 
FROM articles a, (SELECT @rownum:=0) r
ORDER BY date, id) as article_with_rows
WHERE id = 50;

Then decrement the result by 2 put it in the limit statement. For example the above returned 21 for me so I run:

SELECT * 
FROM articles
ORDER BY date, id
LIMIT 19, 3

Gives you your primary record along with it's next and previous records given your stated order.

I tried to do it as a single database call, but couldn't get the LIMIT statement to take a variable as one of it's parameters.

Enumerable.SequenceEqual Method

Determines whether two sequences are equal according to an equality comparer. MS.Docs

Enumerable.SequenceEqual(list1, list2);

This works for all primitive data types. If you need to use it on custom objects you need to implement IEqualityComparer

Defines methods to support the comparison of objects for equality.

IEqualityComparer Interface

Defines methods to support the comparison of objects for equality. MS.Docs for IEqualityComparer

The first ten lowercase letters are string.lowercase[:10] (if you have imported the standard library module string previously, of course;-).

Other ways to "make a string of 10 characters": 'x'*10 (all the ten characters will be lowercase xs;-), ''.join(chr(ord('a')+i) for i in xrange(10)) (the first ten lowercase letters again), etc, etc;-).

sp_change_users_login is deprecated.

Much easier is:

I realize this is an older thread, but for future reference:

As of iPhone SDK 3.0, custom gradients can be implemented very easily, without subclassing or images, by using the new CAGradientLayer:

 UIView *view = [[[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 100)] autorelease];
 CAGradientLayer *gradient = [CAGradientLayer layer];
 gradient.frame = view.bounds;
 gradient.colors = [NSArray arrayWithObjects:(id)[[UIColor blackColor] CGColor], (id)[[UIColor whiteColor] CGColor], nil];
 [view.layer insertSublayer:gradient atIndex:0];

Take a look at the CAGradientLayer docs. You can optionally specify start and end points (in case you don't want a linear gradient that goes straight from the top to the bottom), or even specific locations that map to each of the colors.

That would work depending on what client.get does when passed undefined as its first parameter.

Something like this would be safer:

app.get('/:key?', function(req, res, next) {
    var key = req.params.key;
    if (!key) {
        next();
        return;
    }
    client.get(key, function(err, reply) {
        if(client.get(reply)) {
            res.redirect(reply);
        }
        else {
            res.render('index', {
                link: null
            });
        }
    });
});

There's no problem in calling next() inside the callback.

According to this, handlers are invoked in the order that they are added, so as long as your next route is app.get('/', ...) it will be called if there is no key.

This code is working fine for me.

Encode data with btoa

let data_str = btoa(JSON.stringify(jsonData));
$("#target_id").attr('data-json', data_str);

And then decode it with atob

let tourData = $(this).data("json");
tourData = atob(tourData);

A temp table can be created in the caller and then populated from the called SP.

  create table #GetValuesOutputTable(
     ...   
  );

  exec GetValues; -- populates #GetValuesOutputTable

  select * from #GetValuesOutputTable;

Some advantages of this approach over the "insert exec" is that it can be nested and that it can be used as input or output.

Some disadvantages are that the "argument" is not public, the table creation exists within each caller, and that the name of the table could collide with other temp objects. It helps when the temp table name closely matches the SP name and follows some convention.

Taking it a bit farther, for output only temp tables, the insert-exec approach and the temp table approach can be supported simultaneously by the called SP. This doesn't help too much for chaining SP's because the table still need to be defined in the caller but can help to simplify testing from the cmd line or when calling externally.

  -- The "called" SP
  declare
      @returnAsSelect bit = 0;

  if object_id('tempdb..#GetValuesOutputTable') is null
  begin
      set @returnAsSelect = 1;
      create table #GetValuesOutputTable(
         ...   
      );
  end

  -- populate the table

  if @returnAsSelect = 1
      select * from #GetValuesOutputTable;

You forgot the dot of class selector of result class.

Live Demo

$(".result").hover(
  function () {
    $(this).addClass("result_hover");
  },
  function () {
    $(this).removeClass("result_hover");
  }
);

You can use toggleClass on hover event

Live Demo

 $(".result").hover(function () {
    $(this).toggleClass("result_hover");
 });

Your code is fine. What you are seeing is a linker issue.

If you put your code in a single file like this:

#include <iostream>
#include <string>

using namespace std;

string trim(const string& str)
{
    size_t first = str.find_first_not_of(' ');
    if (string::npos == first)
    {
        return str;
    }
    size_t last = str.find_last_not_of(' ');
    return str.substr(first, (last - first + 1));
}

int main() {
    string s = "abc ";
    cout << trim(s);

}

then do g++ test.cc and run a.out, you will see it works.

You should check if the file that contains the trim function is included in the link stage of your compilation process.

#include"stdio.h"//rmv coding for randam number access

#include"conio.h"

#include"time.h"

void main()
{
    time_t t;
    int rmvivek;

    srand(time(&t));
    rmvivek=1;

    while(rmvivek<=5)
    {
        printf("%c\t",rand()%10);
        rmvivek++;
    }
    getch();
}

Try Fiddler2 it will let you inspect the requests and response. It might be worth noting that Fiddler works with both http and https traffic.

Seems we could use a new HTML5 feature if the browser version is not a problem:

in HTML files :

<div class="centerBloc">
  I will be in the center
</div>

And in CSS file, we write:

body .centerBloc {
  position: fixed;
  top: 50%;
  left: 50%;
  transform: translate(-50%, -50%);
}

And so the div could be perfectly center in browser.

encodeURIComponent(string) will do it:

encodeURIComponent("Robert'); DROP TABLE Students;--")
//>> "Robert')%3B%20DROP%20TABLE%20Students%3B--"

Passing SQL around in a query string might not be a good plan though,

see this one

A simple solution would be Open Android Studio -> Build -> Analyze Apk... browse and select the APK now you can find the package name and pretty much you can read.

I'm assuming c++ here. If you're using c#, the answer is probably the same, but the syntax will be a bit different. The enum is a set of int values. It's not an object, so you shouldn't be setting it to null. Setting something to null means you are pointing a pointer to an object to address zero. You can't really do that with an int. What you want to do with an int is to set it to a value you wouldn't normally have it at so that you can tel if it's a good value or not. So, set your colour to -1

Color color = -1;

Or, you can start your enum at 1 and set it to zero. If you set the colour to zero as it is right now, you will be setting it to "red" because red is zero in your enum.

So,

enum Color {
red =1
blue,
green
}
//red is 1, blue is 2, green is 3
Color mycolour = 0;

This is impossible as a child's z-index is set to the same stacking index as its parent.

You have already solved the problem by removing the z-index from the parent, keep it like this or make the element a sibling instead of a child.

I'd agree it is interesting to propose a particular style of working. However, unless I have the chance to set the style, I usually follow what's been done for consistency.

Taking a look at the Linux Kernel Commits, the project that started git if you like, http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=bca476139d2ded86be146dae09b06e22548b67f3, they don't follow the 50/72 rule. The first line is 54 characters.

I would say consistency matters. Set up proper means of identifying users who've made commits (user.name, user.email - especially on internal networks. User@OFFICE-1-PC-10293982811111 isn't a useful contact address). Depending on the project, make the appropriate detail available in the commit. It's hard to say what that should be; it might be tasks completed in a development process, then details of what's changed.

I don't believe users should use git one way because certain interfaces to git treat the commits in certain ways.

I should also note there are other ways to find commits. For a start, git diff will tell you what's changed. You can also do things like git log --pretty=format:'%T %cN %ce' to format the options of git log.

Are you trying to protect the variables against modification? If so, then you can use a module pattern:

var CONFIG = (function() {
     var private = {
         'MY_CONST': '1',
         'ANOTHER_CONST': '2'
     };

     return {
        get: function(name) { return private[name]; }
    };
})();

alert('MY_CONST: ' + CONFIG.get('MY_CONST'));  // 1

CONFIG.MY_CONST = '2';
alert('MY_CONST: ' + CONFIG.get('MY_CONST'));  // 1

CONFIG.private.MY_CONST = '2';                 // error
alert('MY_CONST: ' + CONFIG.get('MY_CONST'));  // 1

Using this approach, the values cannot be modified. But, you have to use the get() method on CONFIG :(.

If you don't need to strictly protect the variables value, then just do as suggested and use a convention of ALL CAPS.

As pointed out by others, define studentType outside the function. One more thing, even if you do that, do not create a local studentType instance inside the function. The instance is on the function stack and will not be available when you try to return it. One thing you can however do is create studentType dynamically and return the pointer to it outside the function.

If you look at the language feature implementation status of the .NET Compiler Platform ("Roslyn") you can clearly see that in C# 6.0 this is a planned feature, so in the next release we can do it in the usual way.

According to the following post, you can't do this with log4j: Use MaxBackupIndex in DailyRollingFileAppender -log4j

As far as I know, this functionality was supposed to make it into log4j 2.0 but that effort got sidetracked. According to the logback website, logback is the intended successor to log4j so you might consider using that.

There's an API called SLF4J which provides a common API to logging. It will load up the actual logging implementation at runtime so depending on the configuration that you have provided, it might use java.util.log or log4j or logback or any other library capable of providing logging facilities. There'll be a bit of up-front work to go from using log4j directly to using SLF4J but they provide some tools to automate this process. Once you've converted your code to use SLF4J, switching logging backends should simply be a case of changing the config file.

But can I abort a Task (in .Net 4.0) in the same way not by cancellation mechanism. I want to kill the Task immediately.

Other answerers have told you not to do it. But yes, you can do it. You can supply Thread.Abort() as the delegate to be called by the Task's cancellation mechanism. Here is how you could configure this:

class HardAborter
{
  public bool WasAborted { get; private set; }
  private CancellationTokenSource Canceller { get; set; }
  private Task<object> Worker { get; set; }

  public void Start(Func<object> DoFunc)
  {
    WasAborted = false;

    // start a task with a means to do a hard abort (unsafe!)
    Canceller = new CancellationTokenSource();

    Worker = Task.Factory.StartNew(() => 
      {
        try
        {
          // specify this thread's Abort() as the cancel delegate
          using (Canceller.Token.Register(Thread.CurrentThread.Abort))
          {
            return DoFunc();
          }
        }
        catch (ThreadAbortException)
        {
          WasAborted = true;
          return false;
        }
      }, Canceller.Token);
  }

  public void Abort()
  {
    Canceller.Cancel();
  }

}

disclaimer: don't do this.

Here is an example of what not to do:

 var doNotDoThis = new HardAborter();

 // start a thread writing to the console
 doNotDoThis.Start(() =>
    {
       while (true)
       {
          Thread.Sleep(100);
          Console.Write(".");
       }
       return null;
    });


 // wait a second to see some output and show the WasAborted value as false
 Thread.Sleep(1000);
 Console.WriteLine("WasAborted: " + doNotDoThis.WasAborted);

 // wait another second, abort, and print the time
 Thread.Sleep(1000);
 doNotDoThis.Abort();
 Console.WriteLine("Abort triggered at " + DateTime.Now);

 // wait until the abort finishes and print the time
 while (!doNotDoThis.WasAborted) { Thread.CurrentThread.Join(0); }
 Console.WriteLine("WasAborted: " + doNotDoThis.WasAborted + " at " + DateTime.Now);

 Console.ReadKey();

Blaming the db engine when the query that ran sooo fast on your development machine blows up and choke once you throw some traffic at the application.

You can not use strtotime as your time format is not within the supported date and time formats of PHP.

Therefor, you have to create a valid date format first making use of createFromFormat function.

//creating a valid date format
$newDate = DateTime::createFromFormat('YmdHi', $longdate);

//formating the date as we want
$finalDate = $newDate->format('D'); 

if(stop == true)

or

if(stop)

= is for assignment.

== is for checking condition.

if(stop = true) 

It will assign true to stop and evaluates if(true). So it will always execute the code inside if because stop will always being assigned with true.

This does the same, enhanced with CONTAINS:

Function SingleCellExtract(LookupValue As String, LookupRange As Range, ColumnNumber As Integer, Char As String)
Dim I As Long
Dim xRet As String
For I = 1 To LookupRange.Columns(1).Cells.Count
     If InStr(1, LookupRange.Cells(I, 1), LookupValue) > 0 Then
        If xRet = "" Then
            xRet = LookupRange.Cells(I, ColumnNumber) & Char
        Else
            xRet = xRet & "" & LookupRange.Cells(I, ColumnNumber) & Char
        End If
    End If
Next
SingleCellExtract = Left(xRet, Len(xRet) - 1)
End Function

Use EditorFor rather than TextBoxFor

Normally you want to perform this check atomically with using the result, so stat() is useless. Instead, open() the file read-only first and use fstat(). If it's a directory, you can then use fdopendir() to read it. Or you can try opening it for writing to begin with, and the open will fail if it's a directory. Some systems (POSIX 2008, Linux) also have an O_DIRECTORY extension to open which makes the call fail if the name is not a directory.

Your method with opendir() is also good if you want a directory, but you should not close it afterwards; you should go ahead and use it.

The best version of this I've found on Windows is Joseph Newcomer's "whereis" utility, which is available (with source) from his site.

The article about the development of "whereis" is worth reading.

I would simply do the following to backup all new files from 7 days ago

tar --newer $(date -d'7 days ago' +"%d-%b") -zcf thisweek.tgz .

note you can also replace '7 days ago' with anything that suits your need

Can be : date -d'yesterday' +"%d-%b"

Or even : date -d'first Sunday last month' +"%d-%b"

this worked for me: Do not occupy large files, distribute in several small ones you create file Temp, delete file A and then rename file Temp to A.

import os
import json

def Server():
    i = 0
    while i == 0:
        try:        
                with open(File_Temp, "w") as file:
                    json.dump(DATA, file, indent=2)
                if os.path.exists(File_A):
                    os.remove(File_A)
                os.rename(File_Temp, File_A)
                i = 1
        except OSError as e:
                print ("file locked: " ,str(e))
                time.sleep(1)
            
            
def Clients():
    i = 0
    while i == 0:
        try:
            if os.path.exists(File_A):
                with open(File_A,"r") as file:
                    DATA_Temp = file.read()
            DATA = json.loads(DATA_Temp)
            i = 1
        except OSError as e:
            print (str(e))
            time.sleep(1)

This is quite an old question but there's a much simple way of achieving this.

myButton.userInteractionEnabled = false

This will only disable any touch gestures without changing the appearance of the button

Define an action:

const RESET_ACTION = {
  type: "RESET"
}

Then in each of your reducers assuming you are using switch or if-else for handling multiple actions through each reducer. I am going to take the case for a switch.

const INITIAL_STATE = {
  loggedIn: true
}

const randomReducer = (state=INITIAL_STATE, action) {
  switch(action.type) {
    case 'SOME_ACTION_TYPE':

       //do something with it

    case "RESET":

      return INITIAL_STATE; //Always return the initial state

   default: 
      return state; 
  }
}

This way whenever you call RESET action, you reducer will update the store with default state.

Now, for logout you can handle the like below:

const logoutHandler = () => {
    store.dispatch(RESET_ACTION)
    // Also the custom logic like for the rest of the logout handler
}

Every time a userlogs in, without a browser refresh. Store will always be at default.

store.dispatch(RESET_ACTION) just elaborates the idea. You will most likely have an action creator for the purpose. A much better way will be that you have a LOGOUT_ACTION.

Once you dispatch this LOGOUT_ACTION. A custom middleware can then intercept this action, either with Redux-Saga or Redux-Thunk. Both ways however, you can dispatch another action 'RESET'. This way store logout and reset will happen synchronously and your store will ready for another user login.

Warning: this can introduce security issues that SSL is designed to protect against, rendering your entire codebase insecure. It goes against every recommended practice.

But a really simple fix that worked for me was to call:

curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);

before calling:

curl_exec():

in the php file.

I believe that this disables all verification of SSL certificates.

You can get around the "impedance mismatch" caused by the lack of precision in the DateTimeField/date object comparison -- that can occur if using range -- by using a datetime.timedelta to add a day to last date in the range. This works like:

start = date(2012, 12, 11)
end = date(2012, 12, 18)
new_end = end + datetime.timedelta(days=1)

ExampleModel.objects.filter(some_datetime_field__range=[start, new_end])

As discussed previously, without doing something like this, records are ignored on the last day.

Edited to avoid the use of datetime.combine -- seems more logical to stick with date instances when comparing against a DateTimeField, instead of messing about with throwaway (and confusing) datetime objects. See further explanation in comments below.

This works for me. Has a nice delayed action going on.

var $mouseX = 0, $mouseY = 0;
var $xp = 0, $yp =0;

$(document).mousemove(function(e){
    $mouseX = e.pageX;
    $mouseY = e.pageY;    
});

var $loop = setInterval(function(){
// change 12 to alter damping higher is slower
$xp += (($mouseX - $xp)/12);
$yp += (($mouseY - $yp)/12);
$("#moving_div").css({left:$xp +'px', top:$yp +'px'});  
}, 30);

Nice and simples

Try putting the search condition in a bracket, as shown below. This returns the result of the conditional query inside the bracket. Then test its result to determine if it is negative (i.e. it does not belong to any of the options in the vector), by setting it to FALSE.

SE_CSVLinelist_filtered <- filter(SE_CSVLinelist_clean, 
(where_case_travelled_1 %in% c('Outside Canada','Outside province/territory of residence but within Canada')) == FALSE)

From android API Level 19, when I want to instance JSONArray object I put JSONObject directly as parameter like below:

JSONArray jsonArray=new JSONArray(jsonObject);

JSONArray has constructor to accept object.

We have our Create/Alter scripts under source control. As for the database itself, when you have hundreds of tables and a lot of processing data every minutes, it would be CPU and HDD killer to version all the database. That's why backup is still, according to me, the best way to control your data.

Your port 80 is being used by the system.

1. In Windows “World Wide Publishing" Service is using this port and it's process is system which PID is 4 maximum time and stopping this service(“World Wide Publishing") will free the port 80 and you can connect Apache using this port. To stop the service go to the “Task manager –> Services tab”, right click the “World Wide Publishing Service” and stop.
2. If you don't find there then Then go to "Run > services.msc" and again find there and right click the “World Wide Publishing Service” and stop.
3. If you didn't find “World Wide Publishing Service” there then go to "Run>>resmon.exe>> Network Tab>>Listening Ports" and see which process is using port 80

And from "Overview>>CPU" just Right click on that process and click "End Process Tree". If that process is system that might be a critical issue.

An abbreviated version of your code worked for me,

class Remote: NSObject {

    var data = NSMutableData()

    func connect(query:NSString) {
        var url =  NSURL.URLWithString("http://www.google.com")
        var request = NSURLRequest(URL: url)
        var conn = NSURLConnection(request: request, delegate: self, startImmediately: true)
    }


     func connection(didReceiveResponse: NSURLConnection!, didReceiveResponse response: NSURLResponse!) {
        println("didReceiveResponse")
    }

    func connection(connection: NSURLConnection!, didReceiveData conData: NSData!) {
        self.data.appendData(conData)
    }

    func connectionDidFinishLoading(connection: NSURLConnection!) {
        println(self.data)
    }


    deinit {
        println("deiniting")
    }
}

This is the code I used in the calling class,

class ViewController: UIViewController {

    var remote = Remote()


    @IBAction func downloadTest(sender : UIButton) {
        remote.connect("/apis")
    }

}

You didn't specify in your question where you had this code,

var remote = Remote()
remote.connect("/apis")

If var is a local variable, then the Remote class will be deallocated right after the connect(query:NSString) method finishes, but before the data returns. As you can see by my code, I usually implement reinit (or dealloc up to now) just to make sure when my instances go away. You should add that to your Remote class to see if that's your problem.

}

Let me know if this is what you need. Or some thing is missing. I went through the other answers and found that jquery has been used . I took it on assumption that you need css solution . If I am missing any more point please mention :)

This is defined in the ECMAScript Optional Chaining specification, so we should probably refer to optional chaining when we discuss this. Likely implementation:

const result = a?.b?.c;

The long and short of this one is that the TypeScript team are waiting for the ECMAScript specification to get tightened up, so their implementation can be non-breaking in the future. If they implemented something now, it would end up needing major changes if ECMAScript redefine their specification.

See Optional Chaining Specification

Where something is never going to be standard JavaScript, the TypeScript team can implement as they see fit, but for future ECMAScript additions, they want to preserve semantics even if they give early access, as they have for so many other features.

Short Cuts

So all of JavaScripts funky operators are available, including the type conversions such as...

var n: number = +myString; // convert to number
var b: bool = !!myString; // convert to bool

Manual Solution

But back to the question. I have an obtuse example of how you can do a similar thing in JavaScript (and therefore TypeScript) although I'm definitely not suggesting it is a graceful as the feature you are really after.

(foo||{}).bar;

So if foo is undefined the result is undefined and if foo is defined and has a property named bar that has a value, the result is that value.

I put an example on JSFiddle.

This looks quite sketchy for longer examples.

var postCode = ((person||{}).address||{}).postcode;

Chain Function

If you are desperate for a shorter version while the specification is still up in the air, I use this method in some cases. It evaluates the expression and returns a default if the chain can't be satisfied or ends up null/undefined (note the != is important here, we don't want to use !== as we want a bit of positive juggling here).

function chain<T>(exp: () => T, d: T) {
    try {
        let val = exp();
        if (val != null) {
            return val;
        }
    } catch { }
    return d;
}

let obj1: { a?: { b?: string }} = {
    a: {
        b: 'c'
    }
};

// 'c'
console.log(chain(() => obj1.a.b, 'Nothing'));

obj1 = {
    a: {}
};

// 'Nothing'
console.log(chain(() => obj1.a.b, 'Nothing'));

obj1 = {};

// 'Nothing'
console.log(chain(() => obj1.a.b, 'Nothing'));

obj1 = null;

// 'Nothing'
console.log(chain(() => obj1.a.b, 'Nothing'));

What have you tried? This should work.

h1 { font-size: 20pt; }
h2 { font-size: 16pt; }

I think Amith Koujalgi is correct but also, in cases where the webservice responses are in JSON then it might be more useful to see the results in a clean JSON format instead of a very long string. Just add | grep }| python -mjson.tool to the end of curl commands here is two examples:

GET approach with JSON result

JavaSE and JavaEE both are computing platform which allows the developed software to run.

There are three main computing platform released by Sun Microsystems, which was eventually taken over by the Oracle Corporation. The computing platforms are all based on the Java programming language. These computing platforms are:

Java SE, i.e. Java Standard Edition. It is normally used for developing desktop applications. It forms the core/base API.

Java EE, i.e. Java Enterprise Edition. This was originally known as Java 2 Platform, Enterprise Edition or J2EE. The name was eventually changed to Java Platform, Enterprise Edition or Java EE in version 5. Java EE is mainly used for applications which run on servers, such as web sites.

Java ME, i.e. Java Micro Edition. It is mainly used for applications which run on resource constrained devices (small scale devices) like cell phones, most commonly games.

Generally, you could create a channel and receive a stop signal in the goroutine.

There two way to create channel in this example.

1. channel

2. context. In the example I will demo context.WithCancel

The first demo, use channel:

package main

import "fmt"
import "time"

func do_stuff() int {
    return 1
}

func main() {

    ch := make(chan int, 100)
    done := make(chan struct{})
    go func() {
        for {
            select {
            case ch <- do_stuff():
            case <-done:
                close(ch)
                return
            }
            time.Sleep(100 * time.Millisecond)
        }
    }()

    go func() {
        time.Sleep(3 * time.Second)
        done <- struct{}{}
    }()

    for i := range ch {
        fmt.Println("receive value: ", i)
    }

    fmt.Println("finish")
}

The second demo, use context:

package main

import (
    "context"
    "fmt"
    "time"
)

func main() {
    forever := make(chan struct{})
    ctx, cancel := context.WithCancel(context.Background())

    go func(ctx context.Context) {
        for {
            select {
            case <-ctx.Done():  // if cancel() execute
                forever <- struct{}{}
                return
            default:
                fmt.Println("for loop")
            }

            time.Sleep(500 * time.Millisecond)
        }
    }(ctx)

    go func() {
        time.Sleep(3 * time.Second)
        cancel()
    }()

    <-forever
    fmt.Println("finish")
}

<TextView
 android:id="@+id/phoneNumber"
 android:autoLink="phone"
 android:linksClickable="true"
 android:text="+91 22 2222 2222"
 />

This is how you can open EditText label assigned number on dialer directly.

Sometimes it may be better to use chrome.storage API. It's better then localStorage because you can:

• store information from your content script without the need for message passing between content script and extension;
• store your data as JavaScript objects without serializing them to JSON (localStorage only stores strings).

Here's a simple code demonstrating the use of chrome.storage. Content script gets the url of visited page and timestamp and stores it, popup.js gets it from storage area.

content_script.js

(function () {
    var visited = window.location.href;
    var time = +new Date();
    chrome.storage.sync.set({'visitedPages':{pageUrl:visited,time:time}}, function () {
        console.log("Just visited",visited)
    });
})();

popup.js

(function () {
    chrome.storage.onChanged.addListener(function (changes,areaName) {
        console.log("New item in storage",changes.visitedPages.newValue);
    })
})();

"Changes" here is an object that contains old and new value for a given key. "AreaName" argument refers to name of storage area, either 'local', 'sync' or 'managed'.

Remember to declare storage permission in manifest.json.

manifest.json

...
"permissions": [
    "storage"
 ],
...

For Print Result to text file

we can follow

echo "test data" > test.txt

This will create test.txt file and written "test data"

If you want to append then

echo "test data" >> test.txt

You'd probably use the subprocess module. Something like this:

import subprocess
p = subprocess.Popen(["scp", myfile, destination])
sts = os.waitpid(p.pid, 0)

Where destination is probably of the form user@remotehost:remotepath. Thanks to @Charles Duffy for pointing out the weakness in my original answer, which used a single string argument to specify the scp operation shell=True - that wouldn't handle whitespace in paths.

The module documentation has examples of error checking that you may want to perform in conjunction with this operation.

Ensure that you've set up proper credentials so that you can perform an unattended, passwordless scp between the machines. There is a stackoverflow question for this already.

import { Router } from '@angular/router';
//in your constructor
constructor(public router: Router){}

//navigation 
link.this.router.navigateByUrl('/home');

Alternatively you can use the lodash toPairs method:

const _ = require('lodash');
const map = new Map(_.toPairs({foo: 'bar'}));

I have a workaround using jquery... although we cannot style a particular option, we can style the select itself - and use javascript to change the class of the select based on what is selected. It works sufficiently for simple cases.

$('select.potentially_red').on('change', function() {_x000D_
 if ($(this).val()=='red') {_x000D_
  $(this).addClass('option_red');_x000D_
 } else {_x000D_
  $(this).removeClass('option_red');_x000D_
 }_x000D_
});_x000D_
$('select.potentially_red').each( function() {_x000D_
 if ($(this).val()=='red') {_x000D_
  $(this).addClass('option_red');_x000D_
 } else {_x000D_
  $(this).removeClass('option_red');_x000D_
 }_x000D_
});

.option_red {_x000D_
    background-color: #cc0000; _x000D_
    font-weight: bold; _x000D_
    font-size: 12px; _x000D_
    color: white;_x000D_
}

     <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>_x000D_
<!-- The js will affect all selects which have the class 'potentially_red' -->_x000D_
<select name="color" class="potentially_red">_x000D_
    <option value="red">Red</option>_x000D_
    <option value="white">White</option>_x000D_
    <option value="blue">Blue</option>_x000D_
    <option value="green">Green</option>_x000D_
</select>

Note that the js is in two parts, the each part for initializing everything on the page correctly, the .on('change', ... part for responding to change. I was unable to mangle the js into a function to DRY it up, it breaks it for some reason

svn log -q -v shows paths and hides comments. All the paths are indented so you can search for lines starting with whitespace. Then pipe to cut and sort to tidy up:

svn log --stop-on-copy -q -v | grep '^[[:space:]]'| cut -c6- | sort -u

This gets all the paths mentioned on the branch since its branch point. Note it will list deleted and added, as well as modified files. I just used this to get the stuff I should worry about reviewing on a slightly messy branch from a new dev.

I followed some tips from the rest answers and discovered that these odd actions helped (at least in my case).

1) I added to server block the following:

location ~ \.css {
 add_header Content-Type text/css;
}

I reloaded nginx and got this in error.log:

2015/06/18 11:32:29 [error] 3430#3430: *169 open() "/etc/nginx/html/css/mysite.css" failed (2: No such file or directory)

2) I deleted the rows, reloaded nginx and got working css. I can't explain what happend because my conf file became such as before.

My case was clean xubuntu 14.04 on VirtualBox, nginx/1.9.2, a row 127.51.1.1 mysite in /etc/hosts and pretty simple /etc/nginx/nginx.conf with a server block:

user nginx;
worker_processes 1;

error_log /var/log/nginx/error.log warn;
pid /var/run/nginx.pid;

events {
    worker_connections  1024;
}

http {
    include /etc/nginx/mime.types;

    server {
        listen 80;
        server_name mysite;

        location / {
            root /home/testuser/dev/mysite/;
        }
    }
}
