I used the code example from: http://www.sunshine2k.de/articles/coding/crc/understanding_crc.html#ch5

And also this utility to verify: http://www.sunshine2k.de/coding/javascript/crc/crc_js.html

[Offering a somewhat more descriptive answer than the answer provided by @Ajni.]

This can also be achieved using LINQ fluent syntax:

var list = ctn.Items
    .Where(t=> t.DeliverySelection == true && t.Delivery.SentForDelivery == null)
    .OrderBy(t => t.Delivery.SubmissionDate)
    .Take(5);

Note that each method (Where, OrderBy, Take) that appears in this LINQ statement takes a lambda expression as an argument. Also note that the documentation for Enumerable.Take begins with:

Returns a specified number of contiguous elements from the start of a sequence.

Like this:

<video width="300" height="200" autoplay="autoplay">
  <source src="video/supercoolvideo.mp4" type="video/mp4" />
</video>

controls is a boolean attribute:

Note: The values "true" and "false" are not allowed on boolean attributes. To represent a false value, the attribute has to be omitted altogether.

I got the same error and for the issue was that I was on VPN and I didn't realize that. After disconnecting the VPN and reconnecting the wifi resolved it.

Use the ternary operator

direction == 1 ? dosomething () : dosomethingelse ();

Declare it as a decimal which uses the int variable and divide this by 100

int number = 700
decimal correctNumber = (decimal)number / 100;

Following rajibchowdhury's answer (upvoted), use git rm command which is advised is for removing the special entry in the index indicating a submodule (a 'folder' with a special mode 160000).

If that special entry path isn't referenced in the .gitmodule (like 'Classes/Support/Three20' in the original question), then you need to remove it, in order to avoid the "No submodule mapping found in .gitmodules for path" error message.

You can check all the entries in the index which are referencing submodules:

git ls-files --stage | grep 160000

Previous answer (November 2010)

It is possible that you haven't declared your initial submodule correctly (i.e. without any tail '/' at the end, as described in my old answer, even though your .gitmodule has paths which looks ok in it).

This thread mentions:

do you get the same error when running 'git submodule init' from a fresh clone?
If so, you have something wrong.

If you have no submodules, delete .gitmodules, and any references to submodules in .git/config, and ensure the Pikimal dir does not have a .git dir in it.
If that fixes the problem, check in and do the same on your cruise working copy.

Obviously, don't delete your main .gitmodules file, but look after other extra .gitmodules files in your working tree.

Still in the topic of "incorrect submodule initialization", Jefromi mentions submodules which actually are gitlinks.

See How to track untracked content? in order to convert such a directory to a real submodule.

We can define maximum pool size in following way:

                <pool> 
               <min-pool-size>5</min-pool-size>
                <max-pool-size>200</max-pool-size>
                <prefill>true</prefill>
                <use-strict-min>true</use-strict-min>
                <flush-strategy>IdleConnections</flush-strategy>
                </pool>

There are some cases during development when there is no service yet but you want to simulate it and keep the container alive.

It is very easy to write a bash placeholder that simulates a running service:

while true; do
  sleep 100
done

You replace this by something more serious as the development progress.

I found this maven repo where you could download from directly a zip file containing all the jars you need.

• https://maven.springframework.org/release/org/springframework/spring/
• https://repo.spring.io/release/org/springframework/spring/

Alternate solution: Maven

The solution I prefer is using Maven, it is easy and you don't have to download each jar alone. You can do it with the following steps:

1. Create an empty folder anywhere with any name you prefer, for example spring-source

2. Create a new file named pom.xml

3. Copy the xml below into this file

4. Open the spring-source folder in your console

5. Run mvn install

6. After download finished, you'll find spring jars in /spring-source/target/dependencies

   <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

Also, if you need to download any other spring project, just copy the dependency configuration from its corresponding web page.

For example, if you want to download Spring Web Flow jars, go to its web page, and add its dependency configuration to the pom.xml dependencies, then run mvn install again.

<dependency>
  <groupId>org.springframework.webflow</groupId>
  <artifactId>spring-webflow</artifactId>
  <version>2.3.2.RELEASE</version>
</dependency>

The answer is System.exit(), but not a good thing to do as this aborts the program. Any cleaning up, destroy that you intend to do will not happen.

Setting a reference to the Microsoft Access 12.0 Object Library allows us to test if a table exists using DCount.

Public Function ifTableExists(tblName As String) As Boolean

    If DCount("[Name]", "MSysObjects", "[Name] = '" & tblName & "'") = 1 Then

        ifTableExists = True

    End If

End Function

Implement the routerOnActivate in your @Component and return your promise:

EDIT: This explicitly does NOT work, although the current documentation can be a little hard to interpret on this topic. See Brandon's first comment here for more information: https://github.com/angular/angular/issues/6611

EDIT: The related information on the otherwise-usually-accurate Auth0 site is not correct: https://auth0.com/blog/2016/01/25/angular-2-series-part-4-component-router-in-depth/

EDIT: The angular team is planning a @Resolve decorator for this purpose.

I also see that the page loading (performance) takes a long time on using h:commandLink than h:link. h:link is faster compared to h:commandLink

Broken pipe simply means that the connection has failed. It is reasonable to assume that this is unrecoverable, and to then perform any required cleanup actions (closing connections, etc). I don't believe that you would ever see this simply due to the connection not yet being complete.

If you are using non-blocking mode then the SocketChannel.connect method will return false, and you will need to use the isConnectionPending and finishConnect methods to insure that the connection is complete. I would generally code based upon the expectation that things will work, and then catch exceptions to detect failure, rather than relying on frequent calls to "isConnected".

TLDR; Pandas groupby.agg has a new, easier syntax for specifying (1) aggregations on multiple columns, and (2) multiple aggregations on a column. So, to do this for pandas >= 0.25, use

df.groupby('dummy').agg(Mean=('returns', 'mean'), Sum=('returns', 'sum'))

           Mean       Sum
dummy                    
1      0.036901  0.369012

OR

df.groupby('dummy')['returns'].agg(Mean='mean', Sum='sum')

           Mean       Sum
dummy                    
1      0.036901  0.369012

Pandas >= 0.25: Named Aggregation

Pandas has changed the behavior of GroupBy.agg in favour of a more intuitive syntax for specifying named aggregations. See the 0.25 docs section on Enhancements as well as relevant GitHub issues GH18366 and GH26512.

From the documentation,

To support column-specific aggregation with control over the output column names, pandas accepts the special syntax in GroupBy.agg(), known as “named aggregation”, where

• The keywords are the output column names
• The values are tuples whose first element is the column to select and the second element is the aggregation to apply to that column. Pandas provides the pandas.NamedAgg namedtuple with the fields ['column', 'aggfunc'] to make it clearer what the arguments are. As usual, the aggregation can be a callable or a string alias.

You can now pass a tuple via keyword arguments. The tuples follow the format of (<colName>, <aggFunc>).

import pandas as pd

pd.__version__                                                                                                                            
# '0.25.0.dev0+840.g989f912ee'

# Setup
df = pd.DataFrame({'kind': ['cat', 'dog', 'cat', 'dog'],
                   'height': [9.1, 6.0, 9.5, 34.0],
                   'weight': [7.9, 7.5, 9.9, 198.0]
})

df.groupby('kind').agg(
    max_height=('height', 'max'), min_weight=('weight', 'min'),)

      max_height  min_weight
kind                        
cat          9.5         7.9
dog         34.0         7.5

Alternatively, you can use pd.NamedAgg (essentially a namedtuple) which makes things more explicit.

df.groupby('kind').agg(
    max_height=pd.NamedAgg(column='height', aggfunc='max'), 
    min_weight=pd.NamedAgg(column='weight', aggfunc='min')
)

      max_height  min_weight
kind                        
cat          9.5         7.9
dog         34.0         7.5

It is even simpler for Series, just pass the aggfunc to a keyword argument.

df.groupby('kind')['height'].agg(max_height='max', min_height='min')    

      max_height  min_height
kind                        
cat          9.5         9.1
dog         34.0         6.0       

Lastly, if your column names aren't valid python identifiers, use a dictionary with unpacking:

df.groupby('kind')['height'].agg(**{'max height': 'max', ...})

Pandas < 0.25

In more recent versions of pandas leading upto 0.24, if using a dictionary for specifying column names for the aggregation output, you will get a FutureWarning:

df.groupby('dummy').agg({'returns': {'Mean': 'mean', 'Sum': 'sum'}})
# FutureWarning: using a dict with renaming is deprecated and will be removed 
# in a future version

Using a dictionary for renaming columns is deprecated in v0.20. On more recent versions of pandas, this can be specified more simply by passing a list of tuples. If specifying the functions this way, all functions for that column need to be specified as tuples of (name, function) pairs.

df.groupby("dummy").agg({'returns': [('op1', 'sum'), ('op2', 'mean')]})

        returns          
            op1       op2
dummy                    
1      0.328953  0.032895

Or,

df.groupby("dummy")['returns'].agg([('op1', 'sum'), ('op2', 'mean')])

            op1       op2
dummy                    
1      0.328953  0.032895

For the UPDATE

Use:

UPDATE table1 
   SET col1 = othertable.col2,
       col2 = othertable.col3 
  FROM othertable 
 WHERE othertable.col1 = 123;

For the INSERT

Use:

INSERT INTO table1 (col1, col2) 
SELECT col1, col2 
  FROM othertable

You don't need the VALUES syntax if you are using a SELECT to populate the INSERT values.

I came across this question when I was trying to find multiple filenames that I could not combine into a regular expression as described in @Chris J's answer, here is what worked for me

find . -name one.pdf -o -name two.txt -o -name anotherone.jpg

-o or -or is logical OR. See Finding Files on Gnu.org for more information.

I was running this on CygWin.

As to me, you can first(find version.hpp the version variable is in it, if you know where it is(in ubuntu it usually in /usr/include/boost/version.hpp by default install)):

 locate `boost/version.hpp`

Second show it's version by:

 grep BOOST_LIB_VERSION /usr/include/boost/version.hpp

or

  grep BOOST_VERSION /usr/include/boost/version.hpp.

As to me, I have two version boost installed in my system. Output as below:

xy@xy:~$ locate boost/version.hpp |grep boost

/home/xy/boost_install/boost_1_61_0/boost/version.hpp
/home/xy/boost_install/lib/include/boost/version.hpp
/usr/include/boost/version.hpp

xy@xy:~$ grep BOOST_VERSION /usr/include/boost/version.hpp
#ifndef BOOST_VERSION_HPP
#define BOOST_VERSION_HPP
//  BOOST_VERSION % 100 is the patch level
//  BOOST_VERSION / 100 % 1000 is the minor version
//  BOOST_VERSION / 100000 is the major version
#define BOOST_VERSION 105800
//  BOOST_LIB_VERSION must be defined to be the same as BOOST_VERSION

# or this way more readable
xy@xy:~$ grep BOOST_LIB_VERSION /usr/include/boost/version.hpp
//  BOOST_LIB_VERSION must be defined to be the same as BOOST_VERSION
#define BOOST_LIB_VERSION "1_58"

Show local installed version:

xy@xy:~$ grep BOOST_LIB_VERSION /home/xy/boost_install/lib/include/boost/version.hpp
//  BOOST_LIB_VERSION must be defined to be the same as BOOST_VERSION
#define BOOST_LIB_VERSION "1_61"

As sixty4bit question, if your mysql root user looks to be misconfigured, try to install the configurator extension from mysql official source:

According to www.mcafeesecure.com General Solution for vulnerable to cross-site scripting (XSS) filter function can be:

function xss_cleaner($input_str) {
    $return_str = str_replace( array('<','>',"'",'"',')','('), array('&lt;','&gt;','&apos;','&#x22;','&#x29;','&#x28;'), $input_str );
    $return_str = str_ireplace( '%3Cscript', '', $return_str );
    return $return_str;
}

Solution Steps:

1. Unchecked "Automatically manage signing".

2. Select "Provisioning profile" in "Signing (Release)" section.

3. No signing certificate error will be show.

4. Then below the error has a "Manage Certificates" button. click the button.

5. This window will come. Click the + sign and click "iOS Distribution". xcode will create the private key for your distribution certificate and error will be gone.

This worked for me

Function round_Up_To_Int(n As Double)
    If Math.Round(n) = n Or Math.Round(n) = 0 Then
        round_Up_To_Int = Math.Round(n)
    Else: round_Up_To_Int = Math.Round(n + 0.5)
    End If
End Function

Arrays must have zero based integer indexes in JavaScript. So:

var valueToPush = new Array();
valueToPush[0] = productID;
valueToPush[1] = itemColorTitle;
valueToPush[2] = itemColorPath;
cookie_value_add.push(valueToPush);

Or maybe you want to use objects (which are associative arrays):

var valueToPush = { }; // or "var valueToPush = new Object();" which is the same
valueToPush["productID"] = productID;
valueToPush["itemColorTitle"] = itemColorTitle;
valueToPush["itemColorPath"] = itemColorPath;
cookie_value_add.push(valueToPush);

which is equivalent to:

var valueToPush = { };
valueToPush.productID = productID;
valueToPush.itemColorTitle = itemColorTitle;
valueToPush.itemColorPath = itemColorPath;
cookie_value_add.push(valueToPush);

It's a really fundamental and crucial difference between JavaScript arrays and JavaScript objects (which are associative arrays) that every JavaScript developer must understand.

The answer above with spark-csv is correct but there is an issue - the library creates several files based on the data frame partitioning. And this is not what we usually need. So, you can combine all partitions to one:

df.coalesce(1).
    write.
    format("com.databricks.spark.csv").
    option("header", "true").
    save("myfile.csv")

and rename the output of the lib (name "part-00000") to a desire filename.

This blog post provides more details: https://fullstackml.com/2015/12/21/how-to-export-data-frame-from-apache-spark/

You can use

insert into table_name
(date_field)
values
(TO_DATE('2003/05/03 21:02:44', 'yyyy/mm/dd hh24:mi:ss'));

Hope it helps.

With Git 2.0, git add -A is default: git add . equals git add -A ..

git add <path> is the same as "git add -A <path>" now, so that "git add dir/" will notice paths you removed from the directory and record the removal.
In older versions of Git, "git add <path>" ignored removals.

You can say "git add --ignore-removal <path>" to add only added or modified paths in <path>, if you really want to.

git add -A is like git add :/ (add everything from top git repo folder).
Note that git 2.7 (Nov. 2015) will allow you to add a folder named ":"!
See commit 29abb33 (25 Oct 2015) by Junio C Hamano (gitster).

Note that starting git 2.0 (Q1 or Q2 2014), when talking about git add . (current path within the working tree), you must use '.' in the other git add commands as well.

That means:

"git add -A ." is equivalent to "git add .; git add -u ."

(Note the extra '.' for git add -A and git add -u)

Because git add -A or git add -u would operate (starting git 2.0 only) on the entire working tree, and not just on the current path.

Those commands will operate on the entire tree in Git 2.0 for consistency with "git commit -a" and other commands. Because there will be no mechanism to make "git add -u" behave as if "git add -u .", it is important for those who are used to "git add -u" (without pathspec) updating the index only for paths in the current subdirectory to start training their fingers to explicitly say "git add -u ." when they mean it before Git 2.0 comes.

A warning is issued when these commands are run without a pathspec and when you have local changes outside the current directory, because the behaviour in Git 2.0 will be different from today's version in such a situation.

Try WebClient.DownloadFileAsync(). You can call CancelAsync() by timer with your own timeout.

The System.Math.Round method uses the Double structure, which, as others have pointed out, is prone to floating point precision errors. The simple solution I found to this problem when I encountered it was to use the System.Decimal.Round method, which doesn't suffer from the same problem and doesn't require redifining your variables as decimals:

Decimal.Round(0.575, 2, MidpointRounding.AwayFromZero)

Result: 0.58

You can easily use Node.JS in your web app only for real-time communication. Node.JS is really powerful when it's about WebSockets. Therefore "PHP Notifications via Node.js" would be a great concept.

See this example: Creating a Real-Time Chat App with PHP and Node.js

value="<?php echo htmlspecialchars($name); ?>"

on sql 2008 this is valid

DECLARE @myVariable nvarchar(Max) = 'John said to Emily "Hey there Emily"'
select @myVariable

on sql server 2005, you need to do this

DECLARE @myVariable nvarchar(Max) 
select @myVariable = 'John said to Emily "Hey there Emily"'
select @myVariable

I have noticed some of the other answers here use a bare clone and then mirror push to the new repository, however this does not work for me and when I open the new repository after that, the files look mixed up and not as I expect.

Here is a solution that definitely works for copying the files, although it does not preserve the original repository's revision history.

1. git clone the repository onto your local machine.
2. cd into the project directory and then run rm -rf .git to remove all the old git metadata including commit history, etc.
3. Initialize a fresh git repository by running git init.
4. Run git add . ; git commit -am "Initial commit" - Of course you can call this commit what you want.
5. Set the origin to your new repository git remote add origin https://github.com/user/repo-name (replace the url with the url to your new repository)
6. Push it to your new repository with git push origin master.

This would print the files in those directories line by line.

array=(ww/* ee/* qq/*)
printf "%s\n" "${array[@]}"

It isn't pretty, but it works. If you have access apache commons i would suggest that use that

if (val.length() < 8) {
  for (int i = 0; i < val - 8; i++) {
    val = "0" + val;
  }
}

1. Go to phpmyadmin

2. Open user account section:

   

3. Use EDIT Privileges

4. Change password and username

   

5. Add privileges for database

Because your function is an instance or non-static function you should create an object first.

Program p=new Program();
p.Add(1,1)

First Look at this example :

The C code for a simple C program is given below

struct Foo {
    char a;
    int b;
    double c;
    } foo1,foo2;

void foo_assign(void)
{
    foo1 = foo2;
}
int main(/*char *argv[],int argc*/)
{
    foo_assign();
return 0;
}

The Equivalent ASM Code for foo_assign() is

00401050 <_foo_assign>:
  401050:   55                      push   %ebp
  401051:   89 e5                   mov    %esp,%ebp
  401053:   a1 20 20 40 00          mov    0x402020,%eax
  401058:   a3 30 20 40 00          mov    %eax,0x402030
  40105d:   a1 24 20 40 00          mov    0x402024,%eax
  401062:   a3 34 20 40 00          mov    %eax,0x402034

As you can see that a assignment is simply replaced by a "mov" instruction in assembly, the assignment operator simply means moving data from one memory location to another memory location. The assignment will only do it for immediate members of a structures and will fail to copy when you have Complex datatypes in a structure. Here COMPLEX means that you cant have array of pointers ,pointing to lists.

An array of characters within a structure will itself not work on most compilers, this is because assignment will simply try to copy without even looking at the datatype to be of complex type.

SELECT *, COUNT(*) FROM my_table is not what you want, and it's not really valid SQL, you have to group by all the columns that's not an aggregate.

You'd want something like

SELECT somecolumn,someothercolumn, COUNT(*) 
   FROM my_table 
GROUP BY somecolumn,someothercolumn

You basically have two options, either define it as a service, or place it on your root scope. I would suggest that you make a service out of it to avoid polluting the root scope. You create a service and make it available in your controller like this:

<!doctype html>
<html ng-app="myApp">
<head>
    <script src="http://code.jquery.com/jquery-1.9.1.min.js"></script>
    <script src="http://code.angularjs.org/1.1.2/angular.min.js"></script>
    <script type="text/javascript">
    var myApp = angular.module('myApp', []);

    myApp.factory('myService', function() {
        return {
            foo: function() {
                alert("I'm foo!");
            }
        };
    });

    myApp.controller('MainCtrl', ['$scope', 'myService', function($scope, myService) {
        $scope.callFoo = function() {
            myService.foo();
        }
    }]);
    </script>
</head>
<body ng-controller="MainCtrl">
    <button ng-click="callFoo()">Call foo</button>
</body>
</html>

If that's not an option for you, you can add it to the root scope like this:

<!doctype html>
<html ng-app="myApp">
<head>
    <script src="http://code.jquery.com/jquery-1.9.1.min.js"></script>
    <script src="http://code.angularjs.org/1.1.2/angular.min.js"></script>
    <script type="text/javascript">
    var myApp = angular.module('myApp', []);

    myApp.run(function($rootScope) {
        $rootScope.globalFoo = function() {
            alert("I'm global foo!");
        };
    });

    myApp.controller('MainCtrl', ['$scope', function($scope){

    }]);
    </script>
</head>
<body ng-controller="MainCtrl">
    <button ng-click="globalFoo()">Call global foo</button>
</body>
</html>

That way, all of your templates can call globalFoo() without having to pass it to the template from the controller.

Here is a working example.

Keypoints are:

• Declaration of Accounts
• Use of JsonProperty attribute

.

using (WebClient wc = new WebClient())
{
    var json = wc.DownloadString("http://coderwall.com/mdeiters.json");
    var user = JsonConvert.DeserializeObject<User>(json);
}

-

public class User
{
    /// <summary>
    /// A User's username. eg: "sergiotapia, mrkibbles, matumbo"
    /// </summary>
    [JsonProperty("username")]
    public string Username { get; set; }

    /// <summary>
    /// A User's name. eg: "Sergio Tapia, John Cosack, Lucy McMillan"
    /// </summary>
    [JsonProperty("name")]
    public string Name { get; set; }

    /// <summary>
    /// A User's location. eh: "Bolivia, USA, France, Italy"
    /// </summary>
    [JsonProperty("location")]
    public string Location { get; set; }

    [JsonProperty("endorsements")]
    public int Endorsements { get; set; } //Todo.

    [JsonProperty("team")]
    public string Team { get; set; } //Todo.

    /// <summary>
    /// A collection of the User's linked accounts.
    /// </summary>
    [JsonProperty("accounts")]
    public Account Accounts { get; set; }

    /// <summary>
    /// A collection of the User's awarded badges.
    /// </summary>
    [JsonProperty("badges")]
    public List<Badge> Badges { get; set; }
}

public class Account
{
    public string github;
}

public class Badge
{
    [JsonProperty("name")]
    public string Name;
    [JsonProperty("description")]
    public string Description;
    [JsonProperty("created")]
    public string Created;
    [JsonProperty("badge")]
    public string BadgeUrl;
}

@Frode F. gave the right answer.

By the Way Invoke-WebRequest also prints you the 200 OK and a lot of bla, bla, bla... which might be useful but I still prefer the Invoke-RestMethod which is lighter.

Also, keep in mind that you need to use | ConvertTo-Json for the body only, not the header:

$body = @{
 "UserSessionId"="12345678"
 "OptionalEmail"="[email protected]"
} | ConvertTo-Json

$header = @{
 "Accept"="application/json"
 "connectapitoken"="97fe6ab5b1a640909551e36a071ce9ed"
 "Content-Type"="application/json"
} 

Invoke-RestMethod -Uri "http://MyServer/WSVistaWebClient/RESTService.svc/member/search" -Method 'Post' -Body $body -Headers $header | ConvertTo-HTML

and you can then append a | ConvertTo-HTML at the end of the request for better readability

Change the version number to 2.19.1 works for me :)

For python selenium,

Importing the library,

from selenium.webdriver.common.keys import Keys

Use this code to press any key you want,

Anyelement.send_keys(Keys.RETURN)

You can find all the key names by searching this selenium.webdriver.common.keys.

you can use this on your button click activity

Intent webOpen = new Intent(android.content.Intent.ACTION_VIEW);
            WebOpen.setData(Uri.parse("http://www.google.com"));
                startActivity(myWebLink);

and import this on your code

import android.net.Uri;

Before going into Bucketing, we need to understand what Partitioning is. Let us take the below table as an example. Note that I have given only 12 records in the below example for beginner level understanding. In real-time scenarios you might have millions of records.

PARTITIONING
---------------------
Partitioning is used to obtain performance while querying the data. For example, in the above table, if we write the below sql, it need to scan all the records in the table which reduces the performance and increases the overhead.

select * from sales_table where product_id='P1'

To avoid full table scan and to read only the records related to product_id='P1' we can partition (split hive table's files) into multiple files based on the product_id column. By this the hive table's file will be split into two files one with product_id='P1' and other with product_id='P2'. Now when we execute the above query, it will scan only the product_id='P1' file.

../hive/warehouse/sales_table/product_id=P1
../hive/warehouse/sales_table/product_id=P2

The syntax for creating the partition is given below. Note that we should not use the product_id column definition along with the non-partitioned columns in the below syntax. This should be only in the partitioned by clause.

create table sales_table(sales_id int,trans_date date, amount int) 
partitioned by (product_id varchar(10))

Cons : We should be very careful while partitioning. That is, it should not be used for the columns where number of repeating values are very less (especially primary key columns) as it increases the number of partitioned files and increases the overhead for the Name node.

BUCKETING
------------------
Bucketing is used to overcome the cons that I mentioned in the partitioning section. This should be used when there are very few repeating values in a column (example - primary key column). This is similar to the concept of index on primary key column in the RDBMS. In our table, we can take Sales_Id column for bucketing. It will be useful when we need to query the sales_id column.

Below is the syntax for bucketing.

create table sales_table(sales_id int,trans_date date, amount int) 
partitioned by (product_id varchar(10)) Clustered by(Sales_Id) into 3 buckets

Here we will further split the data into few more files on top of partitions.

Since we have specified 3 buckets, it is split into 3 files each for each product_id. It internally uses modulo operator to determine in which bucket each sales_id should be stored. For example, for the product_id='P1', the sales_id=1 will be stored in 000001_0 file (ie, 1%3=1), sales_id=2 will be stored in 000002_0 file (ie, 2%3=2),sales_id=3 will be stored in 000000_0 file (ie, 3%3=0) etc.

It is often required to move both body and html objects together.

$('html,body').animate({
   scrollTop: $("#divToBeScrolledTo").offset().top
});

ShiftyThomas is right:

$("#divToBeScrolledTo").offset().top + 10 // +10 (pixels) reduces the margin.

So to increase the margin use:

$("#divToBeScrolledTo").offset().top - 10 // -10 (pixels) would increase the margin between the top of your window and your element.

A lambda is a type of function, defined inline. Along with a lambda you also usually have some kind of variable type that can hold a reference to a function, lambda or otherwise.

For instance, here's a C# piece of code that doesn't use a lambda:

public Int32 Add(Int32 a, Int32 b)
{
    return a + b;
}

public Int32 Sub(Int32 a, Int32 b)
{
    return a - b;
}

public delegate Int32 Op(Int32 a, Int32 b);

public void Calculator(Int32 a, Int32 b, Op op)
{
    Console.WriteLine("Calculator: op(" + a + ", " + b + ") = " + op(a, b));
}

public void Test()
{
    Calculator(10, 23, Add);
    Calculator(10, 23, Sub);
}

This calls Calculator, passing along not just two numbers, but which method to call inside Calculator to obtain the results of the calculation.

In C# 2.0 we got anonymous methods, which shortens the above code to:

public delegate Int32 Op(Int32 a, Int32 b);

public void Calculator(Int32 a, Int32 b, Op op)
{
    Console.WriteLine("Calculator: op(" + a + ", " + b + ") = " + op(a, b));
}

public void Test()
{
    Calculator(10, 23, delegate(Int32 a, Int32 b)
    {
        return a + b;
    });
    Calculator(10, 23, delegate(Int32 a, Int32 b)
    {
        return a - b;
    });
}

And then in C# 3.0 we got lambdas which makes the code even shorter:

public delegate Int32 Op(Int32 a, Int32 b);

public void Calculator(Int32 a, Int32 b, Op op)
{
    Console.WriteLine("Calculator: op(" + a + ", " + b + ") = " + op(a, b));
}

public void Test()
{
    Calculator(10, 23, (a, b) => a + b);
    Calculator(10, 23, (a, b) => a - b);
}

It seems to me that everyone answering this question is kind-of missing the one critical issue, except @deceze -- use the right tool for the job. You can force a relational database to store almost any type of data and you can force Mongo to handle relational data, but at what cost? You end up introducing complexity at all levels of development and maintenance, from schema design to application code; not to mention the performance hit.

In 2014 we have access to many database servers that handle specific types of data exceptionally well.

• Mongo (document storage)
• Redis (key-value data storage)
• MySQL/Maria/PostgreSQL/Oracle/etc (relational data)
• CouchDB (JSON)

I'm sure I missed some others, like RabbirMQ and Cassandra. My point is, use the right tool for the data you need to store.

If your application requires storage and retrieval of a variety of data really, really fast, (and who doesn't) don't shy away from using multiple data sources for an application. Most popular web frameworks provide support for multiple data sources (Rails, Django, Grails, Cake, Zend, etc). This strategy limits the complexity to one specific area of the application, the ORM or the application's data source interface.

The format for HTTP headers is defined in the HTTP specification. I'm going to talk about HTTP 1.1, for which the specification is RFC 2616. In section 4.2, 'Message Headers', the general structure of a header is defined:

   message-header = field-name ":" [ field-value ]
   field-name     = token
   field-value    = *( field-content | LWS )
   field-content  = <the OCTETs making up the field-value
                    and consisting of either *TEXT or combinations
                    of token, separators, and quoted-string>

This definition rests on two main pillars, token and TEXT. Both are defined in section 2.2, 'Basic Rules'. Token is:

   token          = 1*<any CHAR except CTLs or separators>

In turn resting on CHAR, CTL and separators:

   CHAR           = <any US-ASCII character (octets 0 - 127)>

   CTL            = <any US-ASCII control character
                    (octets 0 - 31) and DEL (127)>

   separators     = "(" | ")" | "<" | ">" | "@"
                  | "," | ";" | ":" | "\" | <">
                  | "/" | "[" | "]" | "?" | "="
                  | "{" | "}" | SP | HT

TEXT is:

   TEXT           = <any OCTET except CTLs,
                    but including LWS>

Where LWS is linear white space, whose definition i won't reproduce, and OCTET is:

   OCTET          = <any 8-bit sequence of data>

There is a note accompanying the definition:

The TEXT rule is only used for descriptive field contents and values
that are not intended to be interpreted by the message parser. Words
of *TEXT MAY contain characters from character sets other than ISO-
8859-1 [22] only when encoded according to the rules of RFC 2047
[14].

So, two conclusions. Firstly, it's clear that the header name must be composed from a subset of ASCII characters - alphanumerics, some punctuation, not a lot else. Secondly, there is nothing in the definition of a header value that restricts it to ASCII or excludes 8-bit characters: it's explicitly composed of octets, with only control characters barred (note that CR and LF are considered controls). Furthermore, the comment on the TEXT production implies that the octets are to be interpreted as being in ISO-8859-1, and that there is an encoding mechanism (which is horrible, incidentally) for representing characters outside that encoding.

So, to respond to @BalusC in particular, it's quite clear that according to the specification, header values are in ISO-8859-1. I've sent high-8859-1 characters (specifically, some accented vowels as used in French) in a header out of Tomcat, and had them interpreted correctly by Firefox, so to some extent, this works in practice as well as in theory (although this was a Location header, which contains a URL, and these characters are not legal in URLs, so this was actually illegal, but under a different rule!).

That said, i wouldn't rely on ISO-8859-1 working across all servers, proxies, and clients, so i would stick to ASCII as a matter of defensive programming.

Another solution could be via pandas Series:

import pandas as pd

a = pd.Series([-2, 1, 5, 3, 8, 5, 6])
b = [1, 2, 5]
c = a[b]

You can then convert c back to a list if you want:

c = list(c)

This is my way i do comments (I think its secure):

<h1>Comment's:</h1>
<?php 
$i  = addslashes($_POST['a']);
$ip = addslashes($_POST['b']);
$a  = addslashes($_POST['c']);
$b  = addslashes($_POST['d']);
if(isset($i) & isset($ip) & isset($a) & isset($b))
{
    $r = mysql_query("SELECT COUNT(*) FROM $db.ban WHERE ip=$ip"); //Check if banned
    $r = mysql_fetch_array($r);
    if(!$r[0]) //Phew, not banned
    {
        if(mysql_query("INSERT INTO $db.com VALUES ($a, $b, $ip, $i)"))
        {
            ?>
            <script type="text/javascript">
                window.location="/index.php?id=".<?php echo $i; ?>;
            </script>
            <?php
        }
        else echo "Error, in mysql query";  
    }
    else echo "Error, You are banned.";
}
$x = mysql_query("SELECT * FROM $db.com WHERE i=$i");
while($r = mysql_fetch_object($x) echo '<div class="c">'.$r->a.'<p>'.$row->b.'</p> </div>';

?>  
<h1>Leave a comment, pl0x:</h1>
<form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post">
    <input type="hidden" name="a" value="<?php $echo $_GET['id']; ?>" />
    <input type="hidden" name="b" value="<?php $echo $_SERVER['REMOTE_ADDR']; ?>" />
    <input type="text" name="c" value="Name"/></br>
    <textarea name="d">
    </textarea>
    <input type="submit" />
</form>

This does it all in one page (This is only the comments section, some configuration is needed)

I'd suggest 3 things in the beginning of your script:

First, as already being said use environment:

#!/usr/bin/env python

Second, set your encoding:

# -*- coding: utf-8 -*-

Third, set some doc string:

"""This is a awesome
    python script!"""

And for sure I would use " " (4 spaces) for ident.
Final header will look like:

#!/usr/bin/env python
# -*- coding: utf-8 -*-

"""This is a awesome
        python script!"""

Best wishes and happy coding.

Here is another simpler take:

df = pd.DataFrame([[0,1,3,4,np.nan,2],[3,5,6,np.nan,3,3]])

inds = np.asarray(df.isnull()).nonzero()

(array([0, 1], dtype=int64), array([4, 3], dtype=int64))

To check a space symbol you can use the following approach

if ( c == ' ' ) { /*...*/ }

To check a space and/or a tab symbol (standard blank characters) you can use the following approach

#include <ctype.h>

//...

if ( isblank( c ) ) { /*...*/ }

To check a white space you can use the following approach

#include <ctype.h>

//...

if ( isspace( c ) ) { /*...*/ }

Partial import from lodash should work in angular 4.1.x using following notation:

let assign = require('lodash/assign');

Or use 'lodash-es' and import in module:

import { assign } from 'lodash-es';

You could do a WHILE loop based on the count on your script length divided by 8000.

EG:

DECLARE @Counter INT
SET @Counter = 0
DECLARE @TotalPrints INT
SET @TotalPrints = (LEN(@script) / 8000) + 1
WHILE @Counter < @TotalPrints 
BEGIN
    -- Do your printing...
    SET @Counter = @Counter + 1
END

The only benefit in using the newInstance() that I see are the following:

1. You will have a single place where all the arguments used by the fragment could be bundled up and you don't have to write the code below everytime you instantiate a fragment.

   Bundle args = new Bundle();
   args.putInt("someInt", someInt);
   args.putString("someString", someString);
   // Put any other arguments
   myFragment.setArguments(args);
   

2. Its a good way to tell other classes what arguments it expects to work faithfully(though you should be able to handle cases if no arguments are bundled in the fragment instance).

So, my take is that using a static newInstance() to instantiate a fragment is a good practice.

Altenative one-liners in plain-old java:

String.format("The date: %tY-%tm-%td", date, date, date);

String.format("The date: %1$tY-%1$tm-%1$td", date);

String.format("Time with tz: %tY-%<tm-%<td %<tH:%<tM:%<tS.%<tL%<tz", date);

String.format("The date and time in ISO format: %tF %<tT", date);

This uses Formatter and relative indexing instead of SimpleDateFormat which is not thread-safe, btw.

Slightly more repetitive but needs just one statement. This may be handy in some cases.

Well you said without redirecting. Well its a javascript code:

<a href="JavaScript:void(0);" onclick="function()">Whatever!</a>

<script type="text/javascript">
function confirm_delete() {
    var delete_confirmed=confirm("Are you sure you want to delete this file?");

    if (delete_confirmed==true) {
       // the php code :) can't expose mine ^_^
    } else { 
       // this one returns the user if he/she clicks no :)
       document.location.href = 'whatever.php';
    }
}
</script>

give it a try :) hope you like it

You could use GCJ to compile your Java program into native code.
At some time they even compiled Eclipse into a native version.

Looks like you created a separate question. I was answering your other question How to change flat file source using foreach loop container in an SSIS package? with the same answer. Anyway, here it is again.

Create two string data type variables namely DirPath and FilePath. Set the value C:\backup\ to the variable DirPath. Do not set any value to the variable FilePath.

Select the variable FilePath and select F4 to view the properties. Set the EvaluateAsExpression property to True and set the Expression property as @[User::DirPath] + "Source" + (DT_STR, 4, 1252) DATEPART("yy" , GETDATE()) + "-" + RIGHT("0" + (DT_STR, 2, 1252) DATEPART("mm" , GETDATE()), 2) + "-" + RIGHT("0" + (DT_STR, 2, 1252) DATEPART("dd" , GETDATE()), 2)

Arrays in JS have two types of properties:

Regular elements and associative properties (which are nothing but objects)

When you define a = new Array(), you are defining an empty array. Note that there are no associative objects yet

When you define b = new Array(2), you are defining an array with two undefined locations.

In both your examples of 'a' and 'b', you are adding associative properties i.e. objects to these arrays.

console.log (a) or console.log(b) prints the array elements i.e. [] and [undefined, undefined] respectively. But since a1/a2 and b1/b2 are associative objects inside their arrays, they can be logged only by console.log(a.a1, a.a2) kind of syntax

use below method for setting padding dynamically

setPadding(int left, int top, int right, int bottom)

Example :

view.setPadding(2,2,2,2);

By default, Visual Studio searches for headers in the folder where your project is ($ProjectDir) and in the default standard libraries directories. If you need to include something that is not placed in your project directory, you need to add the path to the folder to include:

Go to your Project properties (Project -> Properties -> Configuration Properties -> C/C++ -> General) and in the field Additional Include Directories add the path to your .h file.

You can, also, as suggested by Chris Olen, add the path to VC++ Directories field.

Quick steps:

1) Open up the Developer Tools dashboard by going to the Chrome Menu -> Tools -> Developer Tools

2) Click on the settings icon on the right hand side (it's a cog!)

3) Check the box "Disable cache (when DevTools is open)"

4) Now, while the dashboard is up, just hit refresh and JS won't be cached!

I had a similar issue and based on above suggestions I first added "super.setIntegerProperty("loadUrlTimeoutValue", 70000);" but that did not help. So I tried Project -> Clean, that worked and I can launch the app now !

Avinash...

Try to add the class for validation dynamically, when the form has been submitted or the field is invalid. Use the form name and add the 'name' attribute to the input. Example with Bootstrap:

<div class="form-group" ng-class="{'has-error': myForm.$submitted && (myForm.username.$invalid && !myForm.username.$pristine)}">
    <label class="col-sm-2 control-label" for="username">Username*</label>
    <div class="col-sm-10 col-md-9">
        <input ng-model="data.username" id="username" name="username" type="text" class="form-control input-md" required>
    </div>
</div>

It is also important, that your form has the ng-submit="" attribute:

<form name="myForm" ng-submit="checkSubmit()" novalidate>
 <!-- input fields here -->
 ....

  <button type="submit">Submit</button>
</form>

You can also add an optional function for validation to the form:

//within your controller (some extras...)

$scope.checkSubmit = function () {

   if ($scope.myForm.$valid) {
        alert('All good...'); //next step!

   }
   else {
        alert('Not all fields valid! Do something...');
    }

 }

Now, when you load your app the class 'has-error' will only be added when the form is submitted or the field has been touched. Instead of:
!myForm.username.$pristine

You could also use:
myForm.username.$dirty

test -e will test whether a file exists or not. The test command returns a zero value if the test succeeds or 1 otherwise.

Test can be written either as test -e or using []

[ -e "$file_name" ] && grep "poet" $file_name

Unless you actually need the output of grep you can test the return value as grep will return 1 if there are no matches and zero if there are any.

In general terms you can test if a string is non-empty using [ "string" ] which will return 0 if non-empty and 1 if empty

I ran into this issue when trying to get to one of my companies intranet sites. Here is the solution I used:

1. enter about:config into the firefox address bar and agree to continue.
2. search for the preference named security.ssl.enable_ocsp_stapling.
3. double-click this item to change its value to false.

This will lower your security as you will be able to view sites with invalid certs. Firefox will still prompt you that the cert is invalid and you have the choice to proceed forward, so it was worth the risk for me.

I found that as of May, 2012, if you set the frame size so that the minimum pixel area (width • height) is above a certain threshold, it bumps the quality up from 360p to 480p, if you're video is at least 640 x 360.

I've discovered that setting a frame size to 780 x 480 for the embed frame triggers the 480p quality, without distorting the video (scaling up). 640 x 585 also works in this manner. I also used the &hd=1 parameter, but I doubt this has much control if your video is not uploaded in HD (720p or higher).

For instance:

<iframe width="780" height="480" src="http://www.youtube.com/embed/[VIDEO-ID]?rel=0&fs=1&showinfo=0&autohide=1&hd=1"></iframe>

Of course, the drawback is that by setting these static frame dimensions, you will most likely get black bars on the sides or above and below, depending on what you prefer.

If you didn't care about the controls being cut-off, you could go on to use CSS and overflow: hidden to crop the black bars out of the frame, providing you know the exact dimensions of the video.

Hope this helps, and hope the Embed method soon gets discrete quality parameters again one day!

You can use the Conditional Formatting to replace text and NOT effect any formulas. Simply go to the Rule's format where you will see Number, Font, Border and Fill.
Go to the Number tab and select CUSTOM. Then simply type where it says TYPE: what you want to say in QUOTES.

Example.. "OTHER"

Don't post the data as an array. To bind to a list, the key/value pairs should be submitted with the same value for each key.

You should not need a form to do this. You just need a list of key/value pairs, which you can include in the call to $.post.

Step 1

• Search → Find → (goto Tab) Mark
• Find what: ^Session.*$
• Enable the checkbox Bookmark line
• Enable the checkbox Regular expression (under Search Mode)
• Click Mark All (this will find the regex and highlights all the lines and bookmark them)

Step 2

• Search → Bookmark → Remove Bookmarked Lines

I have experienced that kind of issue before and now I'm not using header('Location: pageExample.php'); anymore, instead I'm using javascript's document.location.

Change your:

header('Location: page1.php');

To something like this:

echo "<script type='text/javascript'> document.location = 'page1.php'; </script>";

And what is the purpose of echo $_POST['cancel']; by the way?, just delete that line if what you want is just the redirection. I've been using that <script> every time and it doesn't fail me. :-)

happend to me and was sent to this page, not sure if I had the same scenario, but mine was me trying to "re-merge" that "test" branch.

So I previously merged it but I intentionally exclude some specific changes during that merge, so it clearly has some diff between branches. I was then trying to re-merge it because I realize/forget that I should have and wanted to add a particular change/file that I have previously excluded and I was hoping if I do a merge again would show all changes that I excluded before, but I was wrong and I get the "Already up-to-date" message instead.

Upon reading @Bombe's comment/answer, he is right, and git I think behaves that way, so what I did was to make hard backup of the files on test branch, then checkout the master branch and manually paste the files in it and commit it as if it was new changes.

am not sure if this is the right way or could help others having this same issue, but it did provide solution to my particular case.

This is old, but I put exports in my alias for connecting to the db:

alias schema_one.con="PGOPTIONS='--search_path=schema_one' psql -h host -U user -d database etc"

And for another schema:

alias schema_two.con="PGOPTIONS='--search_path=schema_two' psql -h host -U user -d database etc"

Use the source, Luke.

No, but seriously I found that building Node.js from source, running the tests, and looking at the benchmarks did get me on the right track. From there, the .js files in the lib directory are a good place to look, especially the file http.js.

Update: I wrote this answer over a year ago, and since that time there has an explosion in the number of great resources available for people learning Node.js. Though I still believe diving into the source is worthwhile, I think that there are now better ways to get started. I would suggest some of the books on Node.js that are starting to come out.

Maven is a Framework, Ant is a Toolbox

Maven is a pre-built road car, whereas Ant is a set of car parts. With Ant you have to build your own car, but at least if you need to do any off-road driving you can build the right type of car.

To put it another way, Maven is a framework whereas Ant is a toolbox. If you're content with working within the bounds of the framework then Maven will do just fine. The problem for me was that I kept bumping into the bounds of the framework and it wouldn't let me out.

XML Verbosity

tobrien is a guy who knows a lot about Maven and I think he provided a very good, honest comparison of the two products. He compared a simple Maven pom.xml with a simple Ant build file and he made mention of how Maven projects can become more complex. I think that its worth taking a look at a comparison of a couple of files that you are more likely to see in a simple real-world project. The files below represent a single module in a multi-module build.

First, the Maven file:

<project

</project>

And the equivalent Ant file:

<project name="persist" >

    <import file="../build/common-build.xml" />


    <path id="compile.classpath.main">
        <pathelement location="${common.jar}" />
        <pathelement location="${domain.jar}" />
        <pathelement location="${hibernate.jar}" />
        <pathelement location="${commons-lang.jar}" />
        <pathelement location="${spring.jar}" />
    </path>


    <path id="compile.classpath.test">
        <pathelement location="${classes.dir.main}" />
        <pathelement location="${testng.jar}" />
        <pathelement location="${dbunit.jar}" />
        <pathelement location="${easymock.jar}" />
        <pathelement location="${commons-dbcp.jar}" />
        <pathelement location="${oracle-jdbc.jar}" />
        <path refid="compile.classpath.main" />
    </path>


    <path id="runtime.classpath.test">
        <pathelement location="${classes.dir.test}" />
        <path refid="compile.classpath.test" />
    </path>


</project>

tobrien used his example to show that Maven has built-in conventions but that doesn't necessarily mean that you end up writing less XML. I have found the opposite to be true. The pom.xml is 3 times longer than the build.xml and that is without straying from the conventions. In fact, my Maven example is shown without an extra 54 lines that were required to configure plugins. That pom.xml is for a simple project. The XML really starts to grow significantly when you start adding in extra requirements, which is not out of the ordinary for many projects.

But you have to tell Ant what to do

My Ant example above is not complete of course. We still have to define the targets used to clean, compile, test etc. These are defined in a common build file that is imported by all modules in the multi-module project. Which leads me to the point about how all this stuff has to be explicitly written in Ant whereas it is declarative in Maven.

Its true, it would save me time if I didn't have to explicitly write these Ant targets. But how much time? The common build file I use now is one that I wrote 5 years ago with only slight refinements since then. After my 2 year experiment with Maven, I pulled the old Ant build file out of the closet, dusted it off and put it back to work. For me, the cost of having to explicitly tell Ant what to do has added up to less than a week over a period of 5 years.

Complexity

The next major difference I'd like to mention is that of complexity and the real-world effect it has. Maven was built with the intention of reducing the workload of developers tasked with creating and managing build processes. In order to do this it has to be complex. Unfortunately that complexity tends to negate their intended goal.

When compared with Ant, the build guy on a Maven project will spend more time:

• Reading documentation: There is much more documentation on Maven, because there is so much more you need to learn.
• Educating team members: They find it easier to ask someone who knows rather than trying to find answers themselves.
• Troubleshooting the build: Maven is less reliable than Ant, especially the non-core plugins. Also, Maven builds are not repeatable. If you depend on a SNAPSHOT version of a plugin, which is very likely, your build can break without you having changed anything.
• Writing Maven plugins: Plugins are usually written with a specific task in mind, e.g. create a webstart bundle, which makes it more difficult to reuse them for other tasks or to combine them to achieve a goal. So you may have to write one of your own to workaround gaps in the existing plugin set.

In contrast:

• Ant documentation is concise, comprehensive and all in one place.
• Ant is simple. A new developer trying to learn Ant only needs to understand a few simple concepts (targets, tasks, dependencies, properties) in order to be able to figure out the rest of what they need to know.
• Ant is reliable. There haven't been very many releases of Ant over the last few years because it already works.
• Ant builds are repeatable because they are generally created without any external dependencies, such as online repositories, experimental third-party plugins etc.
• Ant is comprehensive. Because it is a toolbox, you can combine the tools to perform almost any task you want. If you ever need to write your own custom task, it's very simple to do.

Familiarity

Another difference is that of familiarity. New developers always require time to get up to speed. Familiarity with existing products helps in that regard and Maven supporters rightly claim that this is a benefit of Maven. Of course, the flexibility of Ant means that you can create whatever conventions you like. So the convention I use is to put my source files in a directory name src/main/java. My compiled classes go into a directory named target/classes. Sounds familiar doesn't it.

I like the directory structure used by Maven. I think it makes sense. Also their build lifecycle. So I use the same conventions in my Ant builds. Not just because it makes sense but because it will be familiar to anyone who has used Maven before.

I usually do as you describe:
Add a separate column with a random value (=RAND()) and then perform a sort on that column.

Might be more complex and prettyer ways (using macros etc), but this is fast enough and simple enough for me.

I would suggest reading PEP 483 and PEP 484 and watching this presentation by Guido on type hinting.

In a nutshell: Type hinting is literally what the words mean. You hint the type of the object(s) you're using.

Due to the dynamic nature of Python, inferring or checking the type of an object being used is especially hard. This fact makes it hard for developers to understand what exactly is going on in code they haven't written and, most importantly, for type checking tools found in many IDEs (PyCharm and PyDev come to mind) that are limited due to the fact that they don't have any indicator of what type the objects are. As a result they resort to trying to infer the type with (as mentioned in the presentation) around 50% success rate.

To take two important slides from the type hinting presentation:

Why type hints?

1. Helps type checkers: By hinting at what type you want the object to be the type checker can easily detect if, for instance, you're passing an object with a type that isn't expected.
2. Helps with documentation: A third person viewing your code will know what is expected where, ergo, how to use it without getting them TypeErrors.
3. Helps IDEs develop more accurate and robust tools: Development Environments will be better suited at suggesting appropriate methods when know what type your object is. You have probably experienced this with some IDE at some point, hitting the . and having methods/attributes pop up which aren't defined for an object.

Why use static type checkers?

• Find bugs sooner: This is self-evident, I believe.
• The larger your project the more you need it: Again, makes sense. Static languages offer a robustness and control that dynamic languages lack. The bigger and more complex your application becomes the more control and predictability (from a behavioral aspect) you require.
• Large teams are already running static analysis: I'm guessing this verifies the first two points.

As a closing note for this small introduction: This is an optional feature and, from what I understand, it has been introduced in order to reap some of the benefits of static typing.

You generally do not need to worry about it and definitely don't need to use it (especially in cases where you use Python as an auxiliary scripting language). It should be helpful when developing large projects as it offers much needed robustness, control and additional debugging capabilities.

Type hinting with mypy:

In order to make this answer more complete, I think a little demonstration would be suitable. I'll be using mypy, the library which inspired Type Hints as they are presented in the PEP. This is mainly written for anybody bumping into this question and wondering where to begin.

Before I do that let me reiterate the following: PEP 484 doesn't enforce anything; it is simply setting a direction for function annotations and proposing guidelines for how type checking can/should be performed. You can annotate your functions and hint as many things as you want; your scripts will still run regardless of the presence of annotations because Python itself doesn't use them.

Anyways, as noted in the PEP, hinting types should generally take three forms:

• Function annotations (PEP 3107).
• Stub files for built-in/user modules.
• Special # type: type comments that complement the first two forms. (See: What are variable annotations? for a Python 3.6 update for # type: type comments)

Additionally, you'll want to use type hints in conjunction with the new typing module introduced in Py3.5. In it, many (additional) ABCs (abstract base classes) are defined along with helper functions and decorators for use in static checking. Most ABCs in collections.abc are included, but in a generic form in order to allow subscription (by defining a __getitem__() method).

For anyone interested in a more in-depth explanation of these, the mypy documentation is written very nicely and has a lot of code samples demonstrating/describing the functionality of their checker; it is definitely worth a read.

Function annotations and special comments:

First, it's interesting to observe some of the behavior we can get when using special comments. Special # type: type comments can be added during variable assignments to indicate the type of an object if one cannot be directly inferred. Simple assignments are generally easily inferred but others, like lists (with regard to their contents), cannot.

Note: If we want to use any derivative of containers and need to specify the contents for that container we must use the generic types from the typing module. These support indexing.

# Generic List, supports indexing.
from typing import List

# In this case, the type is easily inferred as type: int.
i = 0

# Even though the type can be inferred as of type list
# there is no way to know the contents of this list.
# By using type: List[str] we indicate we want to use a list of strings.
a = []  # type: List[str]

# Appending an int to our list
# is statically not correct.
a.append(i)

# Appending a string is fine.
a.append("i")

print(a)  # [0, 'i']

If we add these commands to a file and execute them with our interpreter, everything works just fine and print(a) just prints the contents of list a. The # type comments have been discarded, treated as plain comments which have no additional semantic meaning.

By running this with mypy, on the other hand, we get the following response:

(Python3)jimmi@jim: mypy typeHintsCode.py
typesInline.py:14: error: Argument 1 to "append" of "list" has incompatible type "int"; expected "str"

Indicating that a list of str objects cannot contain an int, which, statically speaking, is sound. This can be fixed by either abiding to the type of a and only appending str objects or by changing the type of the contents of a to indicate that any value is acceptable (Intuitively performed with List[Any] after Any has been imported from typing).

Function annotations are added in the form param_name : type after each parameter in your function signature and a return type is specified using the -> type notation before the ending function colon; all annotations are stored in the __annotations__ attribute for that function in a handy dictionary form. Using a trivial example (which doesn't require extra types from the typing module):

def annotated(x: int, y: str) -> bool:
    return x < y

The annotated.__annotations__ attribute now has the following values:

{'y': <class 'str'>, 'return': <class 'bool'>, 'x': <class 'int'>}

If we're a complete newbie, or we are familiar with Python 2.7 concepts and are consequently unaware of the TypeError lurking in the comparison of annotated, we can perform another static check, catch the error and save us some trouble:

(Python3)jimmi@jim: mypy typeHintsCode.py
typeFunction.py: note: In function "annotated":
typeFunction.py:2: error: Unsupported operand types for > ("str" and "int")

Among other things, calling the function with invalid arguments will also get caught:

annotated(20, 20)

# mypy complains:
typeHintsCode.py:4: error: Argument 2 to "annotated" has incompatible type "int"; expected "str"

These can be extended to basically any use case and the errors caught extend further than basic calls and operations. The types you can check for are really flexible and I have merely given a small sneak peak of its potential. A look in the typing module, the PEPs or the mypy documentation will give you a more comprehensive idea of the capabilities offered.

Stub files:

Stub files can be used in two different non mutually exclusive cases:

• You need to type check a module for which you do not want to directly alter the function signatures
• You want to write modules and have type-checking but additionally want to separate annotations from content.

What stub files (with an extension of .pyi) are is an annotated interface of the module you are making/want to use. They contain the signatures of the functions you want to type-check with the body of the functions discarded. To get a feel of this, given a set of three random functions in a module named randfunc.py:

def message(s):
    print(s)

def alterContents(myIterable):
    return [i for i in myIterable if i % 2 == 0]

def combine(messageFunc, itFunc):
    messageFunc("Printing the Iterable")
    a = alterContents(range(1, 20))
    return set(a)

We can create a stub file randfunc.pyi, in which we can place some restrictions if we wish to do so. The downside is that somebody viewing the source without the stub won't really get that annotation assistance when trying to understand what is supposed to be passed where.

Anyway, the structure of a stub file is pretty simplistic: Add all function definitions with empty bodies (pass filled) and supply the annotations based on your requirements. Here, let's assume we only want to work with int types for our Containers.

# Stub for randfucn.py
from typing import Iterable, List, Set, Callable

def message(s: str) -> None: pass

def alterContents(myIterable: Iterable[int])-> List[int]: pass

def combine(
    messageFunc: Callable[[str], Any],
    itFunc: Callable[[Iterable[int]], List[int]]
)-> Set[int]: pass

The combine function gives an indication of why you might want to use annotations in a different file, they some times clutter up the code and reduce readability (big no-no for Python). You could of course use type aliases but that sometime confuses more than it helps (so use them wisely).

This should get you familiarized with the basic concepts of type hints in Python. Even though the type checker used has been mypy you should gradually start to see more of them pop-up, some internally in IDEs (PyCharm,) and others as standard Python modules.

I'll try and add additional checkers/related packages in the following list when and if I find them (or if suggested).

Checkers I know of:

• Mypy: as described here.
• PyType: By Google, uses different notation from what I gather, probably worth a look.

Related Packages/Projects:

• typeshed: Official Python repository housing an assortment of stub files for the standard library.

The typeshed project is actually one of the best places you can look to see how type hinting might be used in a project of your own. Let's take as an example the __init__ dunders of the Counter class in the corresponding .pyi file:

class Counter(Dict[_T, int], Generic[_T]):
        @overload
        def __init__(self) -> None: ...
        @overload
        def __init__(self, Mapping: Mapping[_T, int]) -> None: ...
        @overload
        def __init__(self, iterable: Iterable[_T]) -> None: ...

Where _T = TypeVar('_T') is used to define generic classes. For the Counter class we can see that it can either take no arguments in its initializer, get a single Mapping from any type to an int or take an Iterable of any type.

Notice: One thing I forgot to mention was that the typing module has been introduced on a provisional basis. From PEP 411:

A provisional package may have its API modified prior to "graduating" into a "stable" state. On one hand, this state provides the package with the benefits of being formally part of the Python distribution. On the other hand, the core development team explicitly states that no promises are made with regards to the the stability of the package's API, which may change for the next release. While it is considered an unlikely outcome, such packages may even be removed from the standard library without a deprecation period if the concerns regarding their API or maintenance prove well-founded.

So take things here with a pinch of salt; I'm doubtful it will be removed or altered in significant ways, but one can never know.

^** Another topic altogether, but valid in the scope of type-hints: PEP 526: Syntax for Variable Annotations is an effort to replace # type comments by introducing new syntax which allows users to annotate the type of variables in simple varname: type statements.

See What are variable annotations?, as previously mentioned, for a small introduction to these.

Another way to look at it is to consider git rebase master as:

Rebase the current branch on top of master

Here , 'master' is the upstream branch, and that explain why, during a rebase, ours and theirs are reversed.

What about making a simple function?

function isEmptyObject(obj) {
  for(var prop in obj) {
    if (Object.prototype.hasOwnProperty.call(obj, prop)) {
      return false;
    }
  }
  return true;
}

isEmptyObject({}); // true
isEmptyObject({foo:'bar'});  // false

The hasOwnProperty method call directly on the Object.prototype is only to add little more safety, imagine the following using a normal obj.hasOwnProperty(...) call:

isEmptyObject({hasOwnProperty:'boom'});  // false

Note: _{(for the future)} The above method relies on the for...in statement, and this statement iterates only over enumerable properties, in the currently most widely implemented ECMAScript Standard (3rd edition) the programmer doesn't have any way to create non-enumerable properties.

However this has changed now with ECMAScript 5th Edition, and we are able to create non-enumerable, non-writable or non-deletable properties, so the above method can fail, e.g.:

var obj = {};
Object.defineProperty(obj, 'test', { value: 'testVal', 
  enumerable: false,
  writable: true,
  configurable: true
});
isEmptyObject(obj); // true, wrong!!
obj.hasOwnProperty('test'); // true, the property exist!!

An ECMAScript 5 solution to this problem would be:

function isEmptyObject(obj) {
  return Object.getOwnPropertyNames(obj).length === 0;
}

The Object.getOwnPropertyNames method returns an Array containing the names of all the own properties of an object, enumerable or not, this method is being implemented now by browser vendors, it's already on the Chrome 5 Beta and the latest WebKit Nightly Builds.

Object.defineProperty is also available on those browsers and latest Firefox 3.7 Alpha releases.

PHP's inbuilt functions may not work for checking URL if allow_url_fopen setting is set to off for security reasons. Curl is a better option as we would not need to change our code at later stage. Below is the code I used to verify a valid URL:

$url = str_replace(' ', '%20', $url);
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);

Two ways to delete the image from public folder without changing laravel filesystems config file or messing with pure php unlink function:

1. Using the default local storage you need to specify public subfolder:

Storage::delete('public/'.$image_path);

2. Use public storage directly:

Storage::disk('public')->delete($image_path);

I would suggest second way as the best one.

Hope this help other people.

The modern approach is to move away from VBA for important code, and write a .NET managed Add-In using c# or vb.net, there are a lot of resources for this on the www, and you could use the Express version of MS Visual Studio

To add timezone information in Python 3.2+

import datetime

>>> d = datetime.datetime.now(tz=datetime.timezone.utc)
>>> print(d.tzinfo)
'UTC+00:00'

char *p = "String";   means pointer to a string type variable.

char p3[5] = "String"; means you are pre-defining the size of the array to consist of no more than 5 elements. Note that,for strings the null "\0" is also considered as an element.So,this statement would give an error since the number of elements is 7 so it should be:

char p3[7]= "String";

The reason you are getting the the IOException is because you are not catching the IOException of your countLines method. You'll want to do something like this:

public static void main(String[] args) {
  int lines = 0;  

  // TODO - Need to get the filename to populate sFileName.  Could
  // come from the command line arguments.

   try {
       lines = LineCounter.countLines(sFileName);
    }
    catch(IOException ex){
        System.out.println (ex.toString());
        System.out.println("Could not find file " + sFileName);
    }

   if(lines > 0) {
     // Do rest of program.
   }
}

there is a JDK tools executed via command line as following :

native2ascii -encoding utf8 src.txt output.txt

Example :

src.txt

??? ???? ?????? ??????

output.txt

\u0628\u0633\u0645 \u0627\u0644\u0644\u0647 \u0627\u0644\u0631\u062d\u0645\u0646 \u0627\u0644\u0631\u062d\u064a\u0645

If you want to use it in your Java application, you can wrap this command line by :

String pathSrc = "./tmp/src.txt";
String pathOut = "./tmp/output.txt";
String cmdLine = "native2ascii -encoding utf8 " + new File(pathSrc).getAbsolutePath() + " " + new File(pathOut).getAbsolutePath();
Runtime.getRuntime().exec(cmdLine);
System.out.println("THE END");

Then read content of the new file.

if (in_array($id,$user_access_arr)==0)
{
    $this->Session->setFlash(__('Access Denied! You are not eligible to access this.'), 'flash_custom_success');
    return $this->redirect(array('controller'=>'Dashboard','action'=>'index'));
}

The following code is in plain c language and handles blank spaces. It only allocates memory once, so one free() is needed, for each processed line.

I think you have to write each object to an own File or you have to split the one when reading it. You may also try to serialize your list and retrieve that when deserializing.

substring(0,38) means the String has to be 38 characters or longer. If not, the "String index is out of range".

As we all know MySQL was deprecated in PHP 5.5.0, and it was removed in PHP 7.0.0 ref so I have converted accepted answer to mysqli.

<?php
// Name of the file
$filename = 'db.sql';
// MySQL host
$mysql_host = 'localhost';
// MySQL username
$mysql_username = 'root';
// MySQL password
$mysql_password = '123456';
// Database name
$mysql_database = 'mydb';

$connection = mysqli_connect($mysql_host,$mysql_username,$mysql_password,$mysql_database) or die(mysqli_error($connection));

// Temporary variable, used to store current query
$templine = '';
// Read in entire file
$lines = file($filename);
// Loop through each line
foreach ($lines as $line)
{
// Skip it if it's a comment
if (substr($line, 0, 2) == '--' || $line == '')
    continue;

// Add this line to the current segment
$templine .= $line;
// If it has a semicolon at the end, it's the end of the query
if (substr(trim($line), -1, 1) == ';')
{
    // Perform the query
    mysqli_query($connection,$templine) or print('Error performing query \'<strong>' . $templine . '\': ' . mysqli_error($connection) . '<br /><br />');
    // Reset temp variable to empty
    $templine = '';
}
}
 echo "Tables imported successfully";

For the case you do not use "DO": this is my solution for a FOR EACH with nested If conditional statements:

For Each line In lines
    If <1st condition> Then
        <code if 1st condition>
        If <2nd condition> Then
            If <3rd condition> Then
                GoTo ContinueForEach
            Else
                <code else 3rd condition>
            End If
        Else
            <code else 2nd condition>
        End If
    Else
        <code else 1st condition>
    End If
ContinueForEach:

I think Shaz's answer for local variables is hard to understand, though it works for non-recursive functions. Here's another way that I think it's clearer (but it's still his idea, exact same behavior). It's also not accessing the local variables dynamically, just the property of the local variable.

Essentially, it's using a global variable (attached to the function object)

// Here's  a version of it that is more straight forward.
function doIt() {
    doIt.objname = {};
    var someObject = "objname";
    doIt[someObject].value = "value";    
    console.log(doIt.objname);
})();

Which is essentially the same thing as creating a global to store the variable, so you can access it as a property. Creating a global to do this is such a hack.

Here's a cleaner hack that doesn't create global variables, it uses a local variable instead.

function doIt() {
  var scope = {
     MyProp: "Hello"
  };
  var name = "MyProp";
  console.log(scope[name]);
}

See Javascript: interpret string as object reference?

Use raw:

<%=raw @str >

But as @jmort253 correctly says, consider where the HTML really belongs.

Answer

Sigh, it took me 45 minutes to find the answer to this simple question. The answer is: grepl(needle, haystack, fixed=TRUE)

# Correct
> grepl("1+2", "1+2", fixed=TRUE)
[1] TRUE
> grepl("1+2", "123+456", fixed=TRUE)
[1] FALSE

# Incorrect
> grepl("1+2", "1+2")
[1] FALSE
> grepl("1+2", "123+456")
[1] TRUE

Interpretation

grep is named after the linux executable, which is itself an acronym of "Global Regular Expression Print", it would read lines of input and then print them if they matched the arguments you gave. "Global" meant the match could occur anywhere on the input line, I'll explain "Regular Expression" below, but the idea is it's a smarter way to match the string (R calls this "character", eg class("abc")), and "Print" because it's a command line program, emitting output means it prints to its output string.

Now, the grep program is basically a filter, from lines of input, to lines of output. And it seems that R's grep function similarly will take an array of inputs. For reasons that are utterly unknown to me (I only started playing with R about an hour ago), it returns a vector of the indexes that match, rather than a list of matches.

But, back to your original question, what we really want is to know whether we found the needle in the haystack, a true/false value. They apparently decided to name this function grepl, as in "grep" but with a "Logical" return value (they call true and false logical values, eg class(TRUE)).

So, now we know where the name came from and what it's supposed to do. Lets get back to Regular Expressions. The arguments, even though they are strings, they are used to build regular expressions (henceforth: regex). A regex is a way to match a string (if this definition irritates you, let it go). For example, the regex a matches the character "a", the regex a* matches the character "a" 0 or more times, and the regex a+ would match the character "a" 1 or more times. Hence in the example above, the needle we are searching for 1+2, when treated as a regex, means "one or more 1 followed by a 2"... but ours is followed by a plus!

So, if you used the grepl without setting fixed, your needles would accidentally be haystacks, and that would accidentally work quite often, we can see it even works for the OP's example. But that's a latent bug! We need to tell it the input is a string, not a regex, which is apparently what fixed is for. Why fixed? No clue, bookmark this answer b/c you're probably going to have to look it up 5 more times before you get it memorized.

A few final thoughts

The better your code is, the less history you have to know to make sense of it. Every argument can have at least two interesting values (otherwise it wouldn't need to be an argument), the docs list 9 arguments here, which means there's at least 2^9=512 ways to invoke it, that's a lot of work to write, test, and remember... decouple such functions (split them up, remove dependencies on each other, string things are different than regex things are different than vector things). Some of the options are also mutually exclusive, don't give users incorrect ways to use the code, ie the problematic invocation should be structurally nonsensical (such as passing an option that doesn't exist), not logically nonsensical (where you have to emit a warning to explain it). Put metaphorically: replacing the front door in the side of the 10th floor with a wall is better than hanging a sign that warns against its use, but either is better than neither. In an interface, the function defines what the arguments should look like, not the caller (because the caller depends on the function, inferring everything that everyone might ever want to call it with makes the function depend on the callers, too, and this type of cyclical dependency will quickly clog a system up and never provide the benefits you expect). Be very wary of equivocating types, it's a design flaw that things like TRUE and 0 and "abc" are all vectors.

From what I've found online, this is a bug introduced in JDK 1.7.0_45. I've read it will be fixed in the next release of Java, but it's not out yet. Supposedly, it was fixed in 1.7.0_60b01, but I can't find where to download it and 1.7.0_60b02 re-introduces the bug.

I managed to get around the problem by reverting back to JDK 1.7.0_25. Probably not the solution you wanted, but it's the only way I've been able to get it working. Don't forget add JDK 1.7.0_25 in Eclipse after installing the JDK.

Please DO NOT REPLY directly to this email but go to StackOverflow: Class JavaLaunchHelper is implemented in both. One of the two will be used. Which one is undefined

Installing Appropriate file from above link fixed my issue.

Mention: Jason Erickson [[email protected]]. He manages this page fairly well for Windows users.

I do one of two things in this scenario

1. Implement a serialize/deserialize system for my objects and pass them as Strings (in JSON format usually, but you can serialize them any way you'd like)

2. Implement a container that lives outside of the activities so that all my activities can read and write to this container. You can make this container static or use some kind of dependency injection to retrieve the same instance in each activity.

Parcelable works just fine, but I always found it to be an ugly looking pattern and doesn't really add any value that isn't there if you write your own serialization code outside of the model.

Arhhh this got me and I spent a lot of time troubleshooting it. The problem was my tests were being executed in Parellel (the default with XUnit).

To make my test run sequentially I decorated each class with this attribute:

[Collection("Sequential")]

This is how I worked it out: Execute unit tests serially (rather than in parallel)

I mock up my EF In Memory context with GenFu:

private void CreateTestData(TheContext dbContext)
{
    GenFu.GenFu.Configure<Employee>()
       .Fill(q => q.EmployeeId, 3);
    var employee = GenFu.GenFu.ListOf<Employee>(1);

    var id = 1;
    GenFu.GenFu.Configure<Team>()
        .Fill(p => p.TeamId, () => id++).Fill(q => q.CreatedById, 3).Fill(q => q.ModifiedById, 3);
    var Teams = GenFu.GenFu.ListOf<Team>(20);
    dbContext.Team.AddRange(Teams);

    dbContext.SaveChanges();
}

When Creating Test Data, from what I can deduct, it was alive in two scopes (once in the Employee's Tests while the Team tests were running):

public void Team_Index_should_return_valid_model()
{
    using (var context = new TheContext(CreateNewContextOptions()))
    {
        //Arrange
        CreateTestData(context);
        var controller = new TeamController(context);

        //Act
        var actionResult = controller.Index();

        //Assert
        Assert.NotNull(actionResult);
        Assert.True(actionResult.Result is ViewResult);
        var model = ModelFromActionResult<List<Team>>((ActionResult)actionResult.Result);
        Assert.Equal(20, model.Count);
    }
}

Wrapping both Test Classes with this sequential collection attribute has cleared the apparent conflict.

[Collection("Sequential")]

This is working fine in my script. In Express, I am doing this:

exports.index = function(req, res){
  res.render( 'index',  { layout:false, login: req.session.login } );
};

I guess the latest jade is different?

Here is a simple example overriding imageView, you can then also use it in layout designer to preview.

public class RoundedImageView extends ImageView {

    public RoundedImageView(Context context) {
        super(context);
    }

    public RoundedImageView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public RoundedImageView(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
    }

    @TargetApi(Build.VERSION_CODES.LOLLIPOP)
    public RoundedImageView(Context context, AttributeSet attrs, int defStyleAttr, int defStyleRes) {
        super(context, attrs, defStyleAttr, defStyleRes);
    }

    @Override
    public void setImageDrawable(Drawable drawable) {
        float radius = 0.1f;
        Bitmap bitmap = ((BitmapDrawable) drawable).getBitmap();
        RoundedBitmapDrawable rid = RoundedBitmapDrawableFactory.create(getResources(), bitmap);
        rid.setCornerRadius(bitmap.getWidth() * radius);
        super.setImageDrawable(rid);
    }
}

This is for fast solution. Radius is used on all corners and is based of percentage of bitmap width.

I just overrided setImageDrawable and used support v4 method for rounded bitmap drawable.

Usage:

<com.example.widgets.RoundedImageView
        android:layout_width="39dp"
        android:layout_height="39dp"
        android:src="@drawable/your_drawable" />

Preview with imageView and custom imageView:

A slightly faster approach than looping on xrange(N) is:

import itertools

for _ in itertools.repeat(None, N):
    do_something()

There are a number of JavaScript obfuscation tools that are freely available; however, I think it's important to note that it is difficult to obfuscate JavaScript to the point where it cannot be reverse-engineered.

To that end, there are several options that I've used to some degree overtime:

• YUI Compressor. Yahoo!'s JavaScript compressor does a good job of condensing the code that will improve its load time. There is a small level of obfuscation that works relatively well. Essentially, Compressor will change function names, remove white space, and modify local variables. This is what I use most often. This is an open-source Java-based tool.

• JSMin is a tool written by Douglas Crockford that seeks to minify your JavaScript source. In Crockford's own words, "JSMin does not obfuscate, but it does uglify." It's primary goal is to minify the size of your source for faster loading in browsers.

• Free JavaScript Obfuscator. This is a web-based tool that attempts to obfuscate your code by actually encoding it. I think that the trade-offs of its form of encoding (or obfuscation) could come at the cost of filesize; however, that's a matter of personal preference.

This design was not mentioned yet:

Multiple lineage columns

Though it has limitations, if you can bear them, it's very simple and very efficient. Features:

• Columns: one for each lineage level, refers to all the parents up to the root, levels below the current items' level are set to 0 (or NULL)
• There is a fixed limit to how deep the hierarchy can be
• Cheap ancestors, descendants, level
• Cheap insert, delete, move of the leaves
• Expensive insert, delete, move of the internal nodes

Here follows an example - taxonomic tree of birds so the hierarchy is Class/Order/Family/Genus/Species - species is the lowest level, 1 row = 1 taxon (which corresponds to species in the case of the leaf nodes):

CREATE TABLE `taxons` (
  `TaxonId` smallint(6) NOT NULL default '0',
  `ClassId` smallint(6) default NULL,
  `OrderId` smallint(6) default NULL,
  `FamilyId` smallint(6) default NULL,
  `GenusId` smallint(6) default NULL,
  `Name` varchar(150) NOT NULL default ''
);

and the example of the data:

+---------+---------+---------+----------+---------+-------------------------------+
| TaxonId | ClassId | OrderId | FamilyId | GenusId | Name                          |
+---------+---------+---------+----------+---------+-------------------------------+

This is great because this way you accomplish all the needed operations in a very easy way, as long as the internal categories don't change their level in the tree.

If you are looking in linux..

npm update will not work mostly am not sure reason but following steps will help you to resolve issue...

Terminal process to upgrade node 4.x to 6.x.

 $ node -v
 v4.x

Check node path

$ which node
/usr/bin/node

Download latest(6.x) node files from [Download][1]

[1]: https://nodejs.org/dist/v6.9.2/node-v6.9.2-linux-x64.tar.xz and unzip files keep in /opt/node-v6.9.2-linux-x64/.

Now unlink current node and link with latest as following

$ unlink /usr/bin/node
$ ln -s /opt/node-v6.9.2-linux-x64/bin/node node
$ node -v
$ v6.9.2

The legacy solution, before 1.6, was to use .attr and handle the returned value as a bool. The main problem is that the returned type of .attr has changed to string, and therefore the comparison with == true is broken (see http://jsfiddle.net/2vene/1/ (and switch the jquery-version)).

With 1.6 .prop was introduced, which returns a bool.

Nevertheless, I suggest to use .is(), as the returned type is intrinsically bool, like:

$('#dropUnit').is(':disabled');
$('#dropUnit').is(':enabled');

Furthermore .is() is much more natural (in terms of "natural language") and adds more conditions than a simple attribute-comparison (eg: .is(':last'), .is(':visible'), ... please see documentation on selectors).

I'm guessing you didn't run this command after the commit failed so just actually run this to create the remote :

 git remote add origin https://github.com/VijayNew/NewExample.git

And the commit failed because you need to git add some files you want to track.

open is a new access level in Swift 3, introduced with the implementation of

• SE-0117 Allow distinguishing between public access and public overridability

It is available with the Swift 3 snapshot from August 7, 2016, and with Xcode 8 beta 6.

In short:

• An open class is accessible and subclassable outside of the defining module. An open class member is accessible and overridable outside of the defining module.
• A public class is accessible but not subclassable outside of the defining module. A public class member is accessible but not overridable outside of the defining module.

So open is what public used to be in previous Swift releases and the access of public has been restricted. Or, as Chris Lattner puts it in SE-0177: Allow distinguishing between public access and public overridability:

“open” is now simply “more public than public”, providing a very simple and clean model.

In your example, open var hashValue is a property which is accessible and can be overridden in NSObject subclasses.

For more examples and details, have a look at SE-0117.

Well you can also do something interesting like this and do your job by using for loop

#suppose you have variable name
name = "Mr.Suryaa"
for index in range ( len ( name ) ):
    print ( name[index] ) #just like c and c++ 

Answer is

M r . S u r y a a

However since range() create a list of the values which is sequence thus you can directly use the name

for e in name:
    print(e)

This also produces the same result and also looks better and works with any sequence like list, tuple, and dictionary.

We have used tow Built in Functions ( BIFs in Python Community )

1) range() - range() BIF is used to create indexes Example

for i in range ( 5 ) :
can produce 0 , 1 , 2 , 3 , 4

2) len() - len() BIF is used to find out the length of given string

@Mahender, you probably meant the difference between \W (instead of \w) and \b. If not, then I would agree with @BoltClock and @jwismar above. Otherwise continue reading.

\W would match any non-word character and so its easy to try to use it to match word boundaries. The problem is that it will not match the start or end of a line. \b is more suited for matching word boundaries as it will also match the start or end of a line. Roughly speaking (more experienced users can correct me here) \b can be thought of as (\W|^|$). [Edit: as @?mega mentions below, \b is a zero-length match so (\W|^|$) is not strictly correct, but hopefully helps explain the diff]

Quick example: For the string Hello World, .+\W would match Hello_ (with the space) but will not match World. .+\b would match both Hello and World.

I come up with this query

SELECT CASE (SELECT count(*) FROM pragma_table_info(''product'') c WHERE c.name = ''purchaseCopy'') WHEN 0 THEN ALTER TABLE product ADD purchaseCopy BLOB END

• Inner query will return 0 or 1 if column exists.
• Based on the result, alter the column

Another great Treeview jquery plugin is http://www.jstree.com/

For an advance view you should check jquery-treetable
http://ludo.cubicphuse.nl/jquery-plugins/treeTable/doc/

A fine example found here. Powerlord got it right, below, for POST you need HttpURLConnection, instead.

Below is the code to do that,

    URL url = new URL(urlString);
    URLConnection conn = url.openConnection();
    conn.setDoOutput(true);
    conn.setRequestProperty ("Authorization", encodedCredentials);

    OutputStreamWriter writer = new OutputStreamWriter(conn.getOutputStream());

    writer.write(data);
    writer.flush();
    String line;
    BufferedReader reader = new BufferedReader(new 
                                     InputStreamReader(conn.getInputStream()));
    while ((line = reader.readLine()) != null) {
      System.out.println(line);
    }
    writer.close();
    reader.close();

Change URLConnection to HttpURLConnection, to make it POST request.

    HttpURLConnection conn = (HttpURLConnection) url.openConnection();
    conn.setRequestMethod("POST");

Suggestion (...in comments):

You might need to set these properties too,

conn.setRequestProperty( "Content-type", "application/x-www-form-urlencoded");
conn.setRequestProperty( "Accept", "*/*" );

In your .button CSS, try display:inline-block. See this JSFiddle

You could try updating the table to get rid of these characters:

UPDATE dbo.[audit]
  SET UserID = REPLACE(UserID, CHAR(0), '')
  WHERE CHARINDEX(CHAR(0), UserID) > 0;

But then you'll also need to fix whatever is putting this bad data into the table in the first place. In the meantime perhaps try:

SELECT CONVERT(INT, REPLACE(UserID, CHAR(0), ''))
  FROM dbo.[audit];

But that is not a long term solution. Fix the data (and the data type while you're at it). If you can't fix the data type immediately, then you can quickly find the culprit by adding a check constraint:

ALTER TABLE dbo.[audit]
  ADD CONSTRAINT do_not_allow_stupid_data
  CHECK (CHARINDEX(CHAR(0), UserID) = 0);

EDIT

Ok, so that is definitely a 4-digit integer followed by six instances of CHAR(0). And the workaround I posted definitely works for me:

DECLARE @foo TABLE(UserID VARCHAR(32));
INSERT @foo SELECT 0x31353831000000000000;

-- this succeeds:
SELECT CONVERT(INT, REPLACE(UserID, CHAR(0), '')) FROM @foo;

-- this fails:
SELECT CONVERT(INT, UserID) FROM @foo;

Please confirm that this code on its own (well, the first SELECT, anyway) works for you. If it does then the error you are getting is from a different non-numeric character in a different row (and if it doesn't then perhaps you have a build where a particular bug hasn't been fixed). To try and narrow it down you can take random values from the following query and then loop through the characters:

SELECT UserID, CONVERT(VARBINARY(32), UserID)
  FROM dbo.[audit]
  WHERE UserID LIKE '%[^0-9]%';

So take a random row, and then paste the output into a query like this:

DECLARE @x VARCHAR(32), @i INT;
SET @x = CONVERT(VARCHAR(32), 0x...); -- paste the value here
SET @i = 1;
WHILE @i <= LEN(@x)
BEGIN
  PRINT RTRIM(@i) + ' = ' + RTRIM(ASCII(SUBSTRING(@x, @i, 1)))
  SET @i = @i + 1;
END

This may take some trial and error before you encounter a row that fails for some other reason than CHAR(0) - since you can't really filter out the rows that contain CHAR(0) because they could contain CHAR(0) and CHAR(something else). For all we know you have values in the table like:

SELECT '15' + CHAR(9) + '23' + CHAR(0);

...which also can't be converted to an integer, whether you've replaced CHAR(0) or not.

I know you don't want to hear it, but I am really glad this is painful for people, because now they have more war stories to push back when people make very poor decisions about data types.

For an app created with create-react-app I managed to see the version:

1. Open Chrome Dev Tools / Firefox Dev Tools,
2. Search and open main.XXXXXXXX.js file where XXXXXXXX is a builds hash /could be different,
3. Optional: format source by clicking on the {} to show the formatted source,
4. Search as text inside the source for react-dom,
5. in Chrome was found: "react-dom": "^16.4.0",
6. in Firefox was found: 'react-dom': '^16.4.0'

The app was deployed without source map.

you can't use VALUES clause when inserting data using another SELECT query. see INSERT SYNTAX

INSERT INTO user
(
 id, name, username, email, opted_in
)
(
    SELECT id, name, username, email, opted_in
    FROM user
         LEFT JOIN user_permission AS userPerm
            ON user.id = userPerm.user_id
);

In my case, the problem was a conflict of derived dependencies that were been used by other dependencies, and some of those derived dependencies versions were not available, maybe because some deploy that i forgot to do because with workspace resolution everything worked, but when moving to other environment all broke suddenly. And also I was working with version ranges

maven was giving me this error:

Could not resolve dependencies for project MyProject:MyProject:jar:1.0.0: Could not resolve version conflict among Dependency-A:1.0.1 -> Dependency-B:1.1.0 -> Dependency-C:1.0.0, Dependency-X:1.0.1 -> Dependency-Y:1.1.0 -> Dependency-C:1.0.0, Dependency-I:1.0.1 -> Dependency-J:1.1.0 -> Dependency-C:1.0.0

I tried all above and nothing worked, so...

THE SOLUTION: Use LATEST as version in all dependencies, so maven don't need to resolve all dependencies in ranges, wich must be used with care because if you miss to deploy one of the dependencies the build will fail

Only I suggest you to use LATEST if you are working with your own dependencies, otherwise in some third party future version, you could find some compilation or runtime errors

Streams are EventEmitters so you can listen to certain events. As you said there is a finish event for request (previously end).

 var stream = request(...).pipe(...);
 stream.on('finish', function () { ... });

For more information about which events are available you can check the stream documentation page.

myString.substring(str.length,str.length-1)

You should be able to do something like the above - which will get the last character

ECUs (EC2 Computer Units) are a rough measure of processor performance that was introduced by Amazon to let you compare their EC2 instances ("servers").

CPU performance is of course a multi-dimensional measure, so putting a single number on it (like "5 ECU") can only be a rough approximation. If you want to know more exactly how well a processor performs for a task you have in mind, you should choose a benchmark that is similar to your task.

In early 2014, there was a nice benchmarking site comparing cloud hosting offers by tens of different benchmarks, over at CloudHarmony benchmarks. However, this seems gone now (and archive.org can't help as it was a web application). Only an introductory blog post is still available.

Also useful: ec2instances.info, which at least aggregates the ECU information of different EC2 instances for comparison. (Add column "Compute Units (ECU)" to make it work.)

Another possibility is to use the options with data attributes, like this(minimum date 1 week before):

<input class='datepicker' data-date-start-date="-1w">

More info: http://bootstrap-datepicker.readthedocs.io/en/latest/options.html

Make sure your code is in DOM Ready as pointed by rocket-hazmat

.click()

$('#RootNode').click(function(){
  //do something
});

document.getElementById("RootNode").onclick = function(){//do something}

Use event Delegation/

$(document).on("click", "#RootNode", function(){
   //do something
});

Wrap Code in Dom Ready

$(document).ready(function(){
    $('#RootNode').click(function(){
     //do something
    });
});

Since inline events are executed as functions you can simply use arguments.

<p id="p" onclick="doSomething.apply(this, arguments)">

and

function doSomething(e) {
  if (!e) e = window.event;
  // 'e' is the event.
  // 'this' is the P element
}

The 'event' that is mentioned in the accepted answer is actually the name of the argument passed to the function. It has nothing to do with the global event.

Hosting asp.net 4.5/4.5.1 Web application on Local IIS 1)Be Sure IIS Installation before Visual Installation Installataion then aspnet_regiis will already registerd with IIS

If Not Install IIS and then Register aspnet_regiis with IIS by cmd Editor

For VS2012 and 32 bit OS Run Below code on command editor :

1)Install IIS First & then

2)

cd C:\Windows\Microsoft.NET\Framework\v4.0.30319   

  C:\Windows\Microsoft.NET\Framework\v4.0.30319> aspnet_regiis -i

For VS2012 and 64 bit OS Below code on command editor:

1)Install IIS First & then

2)

cd C:\Windows\Microsoft.NET\Framework64\v4.0.30319    
  C:\Windows\Microsoft.NET\Framework64\v4.0.30319> aspnet_regiis -i

BY Following Above Steps Current Version of VS2012 registered with IIS Hosting (VS2012 Web APP)

Create VS2012 Web Application(WebForm/MVC) then Build Application Right Click On WebApplication(WebForm/MVC) go to 'Properties' Click On 'Web' Tab on then 'Use Local IIS Web Server' Then Uncheck 'Use IIS Express' (If Visul Studio 2013 Select 'Local IIS' from Dropdown) Provide Project Url like "http://localhost/MvcDemoApp" Then Click On 'Create Virtual Directory' Button Then Open IIS by Prssing 'Window + R' Run Command and type 'inetmgr' and 'Enter' (or 'OK' Button) Then Expand 'Sites->Default Web Site' you Hosted Successfully. If Still Gets any Server Error like 'The resource cannot be found.' Then Include following code in web.config

 <configuration>
     <system.webServer>
         <modules runAllManagedModulesForAllRequests="true"></modules>

And Run Application

If still problem occurs Check application pool by : In iis Right click on application->Manage Application->Advanced setting->General. you see the application pool. then close advance setting window. click on 'Application Pools' you will see the all application pools in middle window. Right click on application pool in which application hosted(DefaultAppPool). click 'Basic Setting' -> Change .Net FrameWork Version to->.Net FrameWork v4.0.30349

Simplest:

Form form = new Form();
form.add("id", "1");    
form.add("name", "supercobra");
ClientResponse response = webResource
  .type(MediaType.APPLICATION_FORM_URLENCODED_TYPE)
  .post(ClientResponse.class, form);

You can use single line comments:

-- this is a comment
# this is also a comment

Or a multiline comment:

/*
   multiline
   comment
*/

BEGIN
  FOR r IN (select sid,serial# from v$session where username='user')
  LOOP
      EXECUTE IMMEDIATE 'alter system kill session ''' || r.sid  || ',' 
        || r.serial# || ''' immediate';
  END LOOP;
END;

This should work - I just changed your script to add the immediate keyword. As the previous answers pointed out, the kill session only marks the sessions for killing; it does not do so immediately but later when convenient.

From your question, it seemed you are expecting to see the result immediately. So immediate keyword is used to force this.

I believe the author was looking for an equivalent method via the IDE that would generate the code behind and make sure all parameters were in place, etc. Found this from MS:

Creating Event Handlers on the Windows Forms Designer

Coming from a VB background myself, this is what I was looking for, here is the brief version for the click adverse:

1. Click the form or control that you want to create an event handler for.
2. In the Properties window, click the Events button
3. In the list of available events, click the event that you want to create an event handler for.
4. In the box to the right of the event name, type the name of the handler and press ENTER

Update to the answer https://stackoverflow.com/a/4184237/565525:

if you want multiple columns, that can be achived like this:

update file1
set
  (firstfield, secondfield) = (
        select 'stuff' concat 'something from file2', 
               'some secondfield value' 
        from file2
        where substr(file1.field1, 10, 20) = substr(file2.xxx,1,10) )
where
  file1.foo like 'BLAH%'

You could also build out a new Gemfile and run bundle clean --force. This will remove all other gems that aren't included in the new Gemfile.

Given your factorGenerator function, here is a divisorGen that should work:

def divisorGen(n):
    factors = list(factorGenerator(n))
    nfactors = len(factors)
    f = [0] * nfactors
    while True:
        yield reduce(lambda x, y: x*y, [factors[x][0]**f[x] for x in range(nfactors)], 1)
        i = 0
        while True:
            f[i] += 1
            if f[i] <= factors[i][1]:
                break
            f[i] = 0
            i += 1
            if i >= nfactors:
                return

The overall efficiency of this algorithm will depend entirely on the efficiency of the factorGenerator.

If you just want to send an enum you can do something like:

First declare an enum containing some value(which can be passed through intent):

 public enum MyEnum {
    ENUM_ZERO(0),
    ENUM_ONE(1),
    ENUM_TWO(2),
    ENUM_THREE(3);
    private int intValue;

    MyEnum(int intValue) {
        this.intValue = intValue;
    }

    public int getIntValue() {
        return intValue;
    }

    public static MyEnum getEnumByValue(int intValue) {
        switch (intValue) {
            case 0:
                return ENUM_ZERO;
            case 1:
                return ENUM_ONE;
            case 2:
                return ENUM_TWO;
            case 3:
                return ENUM_THREE;
            default:
                return null;
        }
    }
}

Then:

  intent.putExtra("EnumValue", MyEnum.ENUM_THREE.getIntValue());

And when you want to get it:

  NotificationController.MyEnum myEnum = NotificationController.MyEnum.getEnumByValue(intent.getIntExtra("EnumValue",-1);

Piece of cake!

Are you looking something like this short and effective:

http://jsfiddle.net/XBfMV/

$('div').on('click',function(){
  $('div').removeClass('active');
  $(this).addClass('active');
});

you can simply add a general class 'active' for selected div. when a div is clicked, remove the 'active' class, and add it to the clicked div.

Take one example - you have a table with huge data per row. That means every instance of the object is Big.

If you use B tree here then most of the time is spent scanning the pages with data - which is of no use. In databases that is the reason of using B+ Trees to avoid scanning object data.

B+ Trees separate keys from data.

But if your data size is less then you can store them with key which is what B tree does.

If using Java-JSP, What worked for me is to paste below in JSP page

<%@ page contentType="text/html; charset=UTF-8" %>

AskTom is probably the single most helpful resource on best practices on Oracle DBs. (I usually just type "asktom" as the first word of a google query on a particular topic)

I don't think it's really appropriate to speak of design patterns with relational databases. Relational databases are already the application of a "design pattern" to a problem (the problem being "how to represent, store and work with data while maintaining its integrity", and the design being the relational model). Other approches (generally considered obsolete) are the Navigational and Hierarchical models (and I'm nure many others exist).

Having said that, you might consider "Data Warehousing" as a somewhat separate "pattern" or approach in database design. In particular, you might be interested in reading about the Star schema.

I'll tell you how it can be done in eclipse. My dev system - Windows 64bit, Eclipse Luna, Perlipse plugin for eclipse, Strawberry pearl installer. I use perl.exe as my interpreter.

Eclipse > create new perl project > right click project > build path > configure build path > libraries tab > add external source folder > go to the folder where all your perl modules are installed > ok > ok. Done !

You know, all this stuff about the joins and the 'complex transactions' -- but it was Monty himself who, many years ago, explained away the "need" for COMMIT / ROLLBACK, saying that 'all that is done in the logic classes (and not the database) anyway' -- so it's the same thing all over again. What is needed is a dumb yet incredibly tidy and fast data storage/retrieval engine, for 99% of what the web apps do.

It is unfortunately not supported in older versions of MSTest. Apparently there is an extensibility model and you can implement it yourself. Another option would be to use data-driven tests.

My personal opinion would be to just stick with NUnit though...

As of Visual Studio 2012, update 1, MSTest has a similar feature. See McAden's answer.

Add the following to the top of your file # coding=utf-8

If you go to the link in the error you can seen the reason why:

Defining the Encoding

Python will default to ASCII as standard encoding if no other encoding hints are given. To define a source code encoding, a magic comment must be placed into the source files either as first or second line in the file, such as: # coding=

The problem is there is a JavaScript .focus and a jQuery .focus function. This call to .focus is ambiguous. So it doesn't always work. What I do is cast my jQuery object to a JavaScript object and use the JavaScript .focus. This works for me:

$("#goal-input")[0].focus();

using (SqlConnection connection = new SqlConnection(connectionString)) 
{
    connection.Open(); 
    using (SqlCommand command = connection.CreateCommand()) 
    { 
        command.CommandText = "INSERT INTO klant(klant_id,naam,voornaam) VALUES(@param1,@param2,@param3)";  

        command.Parameters.AddWithValue("@param1", klantId));  
        command.Parameters.AddWithValue("@param2", klantNaam));  
        command.Parameters.AddWithValue("@param3", klantVoornaam));  

        command.ExecuteNonQuery(); 
    } 
}

You can use unsigned assemblies if your assembly is also unsigned.

For your case you could also look into numpy.bincount

In [56]: a = np.array([0, 0, 0, 1, 0, 1, 1, 0, 0, 0, 0, 1])

In [57]: np.bincount(a)
Out[57]: array([8, 4])  #count of zeros is at index 0 : 8
                        #count of ones is at index 1 : 4

since iOS 10 you should use:

guard let url = URL(string: linkUrlString) else {
    return
}
    
if #available(iOS 10.0, *) {
    UIApplication.shared.open(url, options: [:], completionHandler: nil)
} else {
    UIApplication.shared.openURL(url)
}

Just pass it in like any other parameter:

def a(x):
    return "a(%s)" % (x,)

def b(f,x):
    return f(x)

print b(a,10)

INSERT INTO def (field_1, field_2, field3) 
VALUES 
('$field_1', (SELECT id_user from user_table where name = 'jhon'), '$field3')

As much as your available memory will allow. There's no size limit except for the heap.

Pressing Shift-Alt-J on the method declaration gives:

/**
 * @param i
 * @return
 */
public int doAction(int i) {
    return i;
}

Try HostingEnvironment.MapPath, which is static.

See this SO question for confirmation that HostingEnvironment.MapPath returns the same value as Server.MapPath: What is the difference between Server.MapPath and HostingEnvironment.MapPath?

I experienced the same issue, it occurred because my ES6 component class was not extending React.Component.

This isn't in the boto3 documentation. This worked for me:

object.get()["Body"].read()

object being an s3 object: http://boto3.readthedocs.org/en/latest/reference/services/s3.html#object

Insert Into FEMALE(ID, Image)
Select '1', BulkColumn 
from Openrowset (Bulk 'D:\thepathofimage.jpg', Single_Blob) as Image

You will also need admin rights to run the query.

Have a look at the config file.

Repository > Repository Settings > Edit config file.

Check if the [user] section exists. If the user section is missing, add it.

Example:

[user]
name = "your name"
email = "your email"

This is probably never going to be seen among all the other responses, but this is the code I came up with, this has the benefit of using the DescriptionAttribute if it exists, but otherwise using the name of the enum value itself.

I used a dictionary because it has a ready made key/value item pattern. A List<KeyValuePair<string,object>> would also work and without the unnecessary hashing, but a dictionary makes for cleaner code.

I get members that have a MemberType of Field and that are literal. This creates a sequence of only members that are enum values. This is robust since an enum cannot have other fields.

public static class ControlExtensions
{
    public static void BindToEnum<TEnum>(this ComboBox comboBox)
    {
        var enumType = typeof(TEnum);

        var fields = enumType.GetMembers()
                              .OfType<FieldInfo>()
                              .Where(p => p.MemberType == MemberTypes.Field)
                              .Where(p => p.IsLiteral)
                              .ToList();

        var valuesByName = new Dictionary<string, object>();

        foreach (var field in fields)
        {
            var descriptionAttribute = field.GetCustomAttribute(typeof(DescriptionAttribute), false) as DescriptionAttribute;

            var value = (int)field.GetValue(null);
            var description = string.Empty;

            if (!string.IsNullOrEmpty(descriptionAttribute?.Description))
            {
                description = descriptionAttribute.Description;
            }
            else
            {
                description = field.Name;
            }

            valuesByName[description] = value;
        }

        comboBox.DataSource = valuesByName.ToList();
        comboBox.DisplayMember = "Key";
        comboBox.ValueMember = "Value";
    }


}

Like the other answers say, you can't remove an item from a collection you're iterating over. You can get around this by explicitly using an Iterator and removing the item there.

Iterator<Item> iter = list.iterator();
while(iter.hasNext()) {
  Item blah = iter.next();
  if(...) {
    iter.remove(); // Removes the 'current' item
  }
}

You can get SVN command-line tools with TortoiseSVN 1.7 or later or get a 6.5mb standalone package from VisualSVN.

Starting with TortoiseSVN 1.7, its installer provides you with an option to install the command-line tools.

It also makes sense to check the Apache Subversion "Binary Packages" page. xD

I tried searching for documentation on the EM7 OpenSource REST API. No luck so far.

http://blog.sciencelogic.com/sciencelogic-em7-the-next-generation/05/2011

There's a lot of talk about OpenSource REST API, but no link to the actual API or any documentation. Maybe I was impatient.

Here are few things you can try out

$a = Invoke-RestMethod -Uri https://IPADDRESS/resource -Credential $cred -certificate $cert 
$a.Results | ConvertFrom-Json

Try this to see if you can filter out the columns that you are getting from the API

$a.Results | ft

or, you can try using this also

$b = Invoke-WebRequest -Uri https://IPADDRESS/resource -Credential $cred -certificate $cert 
$b.Content | ConvertFrom-Json

Curl Style Headers

$b.Headers

I tested the IRM / IWR with the twitter JSON api.

$a = Invoke-RestMethod http://search.twitter.com/search.json?q=PowerShell 

Hope this helps.

Here's a solution which will work even when JavaScript is disabled:

<form action="login.html">
    <button type="submit">Login</button>
</form>

The trick is to surround the button with its own <form> tag.

I personally prefer the <button> tag, but you can do it with <input> as well:

<form action="login.html">
    <input type="submit" value="Login"/>
</form>

select * from information_schema.REFERENTIAL_CONSTRAINTS where 
UNIQUE_CONSTRAINT_SCHEMA = 'TABLE_NAME' 

This will list the column with TABLE_NAME and REFERENCED_COLUMN_NAME.

It's possible you forgot a sheet1 each time somewhere before the columns.count, or it will count the activesheet columns and not the sheet1's.

Also, shouldn't it be xltoleft instead of xltoright? (Ok it is very late here, but I think I know my right from left) I checked it, you must write xltoleft.

lastColumn = Sheet1.Cells(1, sheet1.Columns.Count).End(xlToleft).Column

You can transfer array from javascript to PHP...

Javascript... ArraySender.html

<script language="javascript">

//its your javascript, your array can be multidimensional or associative

plArray = new Array();
plArray[1] = new Array(); plArray[1][0]='Test 1 Data'; plArray[1][1]= 'Test 1'; plArray[1][2]= new Array();
plArray[1][2][0]='Test 1 Data Dets'; plArray[1][2][1]='Test 1 Data Info'; 
plArray[2] = new Array(); plArray[2][0]='Test 2 Data'; plArray[2][1]= 'Test 2';
plArray[3] = new Array(); plArray[3][0]='Test 3 Data'; plArray[3][1]= 'Test 3'; 
plArray[4] = new Array(); plArray[4][0]='Test 4 Data'; plArray[4][1]= 'Test 4'; 
plArray[5] = new Array(); plArray[5]["Data"]='Test 5 Data'; plArray[5]["1sss"]= 'Test 5'; 

function convertJsArr2Php(JsArr){
    var Php = '';

            Php += '\'' + i + '\' => ' + convertJsArr2Php(JsArr[i]);

                Php += ', ';
            }
        }
        Php += ')';
        return Php;
    }
    else{
        return '\'' + JsArr + '\'';
    }
}


function ajaxPost(str, plArrayC){

    xmlhttp.send('Array=' + plArrayC);
}

ajaxPost('ArrayReader.php',convertJsArr2Php(plArray));
</script>

and PHP Code... ArrayReader.php

<?php

ag (the silver searcher) has pretty simple syntax for this

       -G --file-search-regex PATTERN
          Only search files whose names match PATTERN.

so

ag -G *.h -G *.cpp CP_Image <path>

svn co svn://path destination

To specify current directory, use a "." for your destination directory:

svn checkout file:///home/landonwinters/svn/waterproject/trunk .

Some form of rounding is often unavoidable when dealing with floating point numbers. This is because numbers that you can express exactly in base 10 cannot always be expressed exactly in base 2 (which your computer uses).

For example:

>>> .1
0.10000000000000001

In this case, you're seeing .1 converted to a string using repr:

>>> repr(.1)
'0.10000000000000001'

I believe python chops off the last few digits when you use str() in order to work around this problem, but it's a partial workaround that doesn't substitute for understanding what's going on.

>>> str(.1)
'0.1'

I'm not sure exactly what problems "rounding" is causing you. Perhaps you would do better with string formatting as a way to more precisely control your output?

e.g.

>>> '%.5f' % .1
'0.10000'
>>> '%.5f' % .12345678
'0.12346'

Anonymous FTP usage is covered by RFC 1635: How to Use Anonymous FTP:

What is Anonymous FTP?

Anonymous FTP is a means by which archive sites allow general access to their archives of information. These sites create a special account called "anonymous".

…

Traditionally, this special anonymous user account accepts any string as a password, although it is common to use either the password "guest" or one's electronic mail (e-mail) address. Some archive sites now explicitly ask for the user's e-mail address and will not allow login with the "guest" password. Providing an e-mail address is a courtesy that allows archive site operators to get some idea of who is using their services.

These are general recommendations, though. Each FTP server may have its own guidelines.

For sample use of the ftp command on anonymous FTP access, see appendix A:

On a mac it should ideally be at : /Applications/Android Studio.app/Contents/gradle/gradle-2.14.1

(Replace the version string with the latest)

To achieve your current need, you need to fire below query

> insert overwrite table student 
> select *from student 
> where id <> 1;

This will delete current table and create new table with same name with all rows except the rows that you want to exclude/delete

I tried this on Hive 1.2.1

You have to ask users to store the 11 character code from the youtube video.

For e.g. http://www.youtube.com/watch?v=Ahg6qcgoay4

The eleven character code is : Ahg6qcgoay4

You then take this code and place it in your database. Then wherever you want to place the youtube video in your page, load the character from the database and put the following code:-

e.g. for Ahg6qcgoay4 it will be :

<object width="425" height="350" data="http://www.youtube.com/v/Ahg6qcgoay4" type="application/x-shockwave-flash"><param name="src" value="http://www.youtube.com/v/Ahg6qcgoay4" /></object>

You can do it by walking the stack backwards. In reality, though, it's frequently easier to add an identifier onto a call stack at the beginning of each function and pop it at the end, then just walk that printing the contents. It's a bit of a PITA, but it works well and will save you time in the end.

Use the code below:

using Newtonsoft.Json;
string JSONString = string.Empty;
JSONString = JsonConvert.SerializeObject(ds.Tables[0]);

I'm updating this answer since is very useful. Just add readonly to the input.

So the form will be:

<form action="/Media/Add">
    <input type="hidden" name="Id" value="123" />
    <input type="textbox" name="Percentage" value="100" readonly/>
</form>

Using CSS+

<div class="EXTENDER">
  <div class="PADDER-CENTER">
    <div contentEditable="true">Edit this text...</div>
  </div>
</div>

On Fedora 24: For Python 3.x

sudo dnf install postgresql-devel python3-devel

sudo dnf install redhat-rpm-config

Activate your Virtual Environment:

pip install psycopg2

Use glob. There are comprehensive guide how to open all files from dir: PHP: Using functional programming for listing files and directories

If you using JavaScript to test your Regex, try \\. instead of \..

It acts on the same way because JS remove first backslash.

With C# 8 onwards you can make it even more concise with the new switch. And with the use of discard option _ you can avoid creating innecesary variables when you don't need them, like this:

        return document switch {
            Invoice _ => "Is Invoice",
            ShippingList _ => "Is Shipping List",
            _ => "Unknown"
        };

Invoice and ShippingList are classes and document is an object that can be either of them.

Hide response header and then add a new custom header value

Adding a header with add_header works fine with proxy pass, but if there is an existing header value in the response it will stack the values.

If you want to set or replace a header value (for example replace the Access-Control-Allow-Origin header to match your client for allowing cross origin resource sharing) then you can do as follows:

# 1. hide the Access-Control-Allow-Origin from the server response
proxy_hide_header Access-Control-Allow-Origin;
# 2. add a new custom header that allows all * origins instead
add_header Access-Control-Allow-Origin *;

So proxy_hide_header combined with add_header gives you the power to set/replace response header values.

Similar answer can be found here on ServerFault

UPDATE:

Note: proxy_set_header is for setting request headers before the request is sent further, not for setting response headers (these configuration attributes for headers can be a bit confusing).

Heredoc sounds more convenient for this purpose. It is used to send multiple commands to a command interpreter program like ex or cat

cat << EndOfMessage
This is line 1.
This is line 2.
Line 3.
EndOfMessage

The string after << indicates where to stop.

To send these lines to a file, use:

cat > $FILE <<- EOM
Line 1.
Line 2.
EOM

You could also store these lines to a variable:

read -r -d '' VAR << EOM
This is line 1.
This is line 2.
Line 3.
EOM

This stores the lines to the variable named VAR.

When printing, remember the quotes around the variable otherwise you won't see the newline characters.

echo "$VAR"

Even better, you can use indentation to make it stand out more in your code. This time just add a - after << to stop the tabs from appearing.

read -r -d '' VAR <<- EOM
    This is line 1.
    This is line 2.
    Line 3.
EOM

But then you must use tabs, not spaces, for indentation in your code.

try this, it works. (in the example below i have 3 cells for example.)

    func scrollViewDidEndDecelerating(scrollView: UIScrollView) {
    let visibleRect = CGRect(origin: self.collectionView.contentOffset, size: self.collectionView.bounds.size)
    let visiblePoint = CGPointMake(CGRectGetMidX(visibleRect), CGRectGetMidY(visibleRect))
    let visibleIndexPath = self.collectionView.indexPathForItemAtPoint(visiblePoint)
    if let v = visibleIndexPath {
        switch v.item {
        case 0: setImageDescription()
            break
        case 1: setImageConditions()
            break
        case 2: setImageResults()
            break
        default: break
        }
    }

You can do this a couple of ways.

Via the "Solution Explorer"

1. Simply right-click the "References" folder and select "Manage NuGet Packages..."
2. Once that window comes up click on the option labeled "Online" in the left most part of the dialog.
3. Then in the search bar in the upper right type "json.net"
4. Click "Install" and you're done.

Via the "Package Manager Console"

1. Open the console. "View" > "Other Windows" > "Package Manager Console"
2. Then type the following:

   Install-Package Newtonsoft.Json

For more info on how to use the "Package Manager Console" check out the nuget docs.

This works, even done is printed.

  SpringApplication.run(MyApplication.class, args).close();
  System.out.println("done");

So adding .close() after run()

Explanation:

public ConfigurableApplicationContext run(String... args)

Run the Spring application, creating and refreshing a new ApplicationContext. Parameters:

args - the application arguments (usually passed from a Java main method)

Returns: a running ApplicationContext

and:

void close() Close this application context, releasing all resources and locks that the implementation might hold. This includes destroying all cached singleton beans. Note: Does not invoke close on a parent context; parent contexts have their own, independent lifecycle.

This method can be called multiple times without side effects: Subsequent close calls on an already closed context will be ignored.

So basically, it will not close the parent context, that's why the VM doesn't quit.

Button btn=(Button)findViewById(R.id.btn);
btn.setVisibility(8);

I haven't used it but you might want to try the jQuery plugin written by Mark Gibson

It adds the two functions: $.toJSON(value), $.parseJSON(json_str, [safe]).

Even simpler is to use:

(?P<project_id>\w+|)

The "(a|b)" means a or b, so in your case it would be one or more word characters (\w+) or nothing.

So it would look like:

url(
    r'^project_config/(?P<product>\w+)/(?P<project_id>\w+|)/$',
    'tool.views.ProjectConfig',
    name='project_config'
),

Run the script as source= to run in debug mode as well.

source= ./myscript.sh

I've created a class which helps to reduce errors in setting up custom handlers and takes advantage of the system property so there are no issues with calling a method first or not being in the right container. There's also an exception class if you get things wrong:
