If "keep a positive one" means you want a positive number to stay positive, but also convert a negative number to positive, use abs():

>>> abs(-1)
1
>>> abs(1)
1

-num will equal to num for Integer.MIN_VALUE as

 Integer.MIN_VALUE =  Integer.MIN_VALUE * -1

Let's define a list first:

lst=[1,2,3]

You can directly write your list to a file:

f=open("filename.txt","w")
f.write(str(lst))
f.close()

To read your list from text file first you read the file and store in a variable:

f=open("filename.txt","r")
lst=f.read()
f.close()

The type of variable lst is of course string. You can convert this string into array using eval function.

lst=eval(lst)

You will need to assign an ID to the checkbox:

<input id="checkboxId" type="checkbox" checked="" name="copyNewAddrToBilling">

and then in JavaScript:

document.getElementById("checkboxId").checked = false;

For anyone still coming to this post, the other option is to simply omit the parentheses:

Sub SomeOtherSub(Stattyp As String)
    'Daty and the other variables are defined here

    CatSubProduktAreakum Stattyp, Daty + UBound(SubCategories) + 2

End Sub

The Call keywords is only really in VBA for backwards compatibilty and isn't actually required.

If however, you decide to use the Call keyword, then you have to change your syntax to suit.

'// With Call
Call Foo(Bar)

'// Without Call
Foo Bar

Both will do exactly the same thing.

That being said, there may be instances to watch out for where using parentheses unnecessarily will cause things to be evaluated where you didn't intend them to be (as parentheses do this in VBA) so with that in mind the better option is probably to omit the Call keyword and the parentheses

node v6.6.0

If you just use in development. You can do this:

npm i babel-cli babel-plugin-transform-async-to-generator babel-polyfill --save-dev

the package.json would be like this:

"devDependencies": {
   "babel-cli": "^6.18.0",
   "babel-plugin-transform-async-to-generator": "^6.16.0",
   "babel-polyfill": "^6.20.0"
}

create .babelrc file and write this:

{
  "plugins": ["transform-async-to-generator"]
}

and then, run your async/await script like this:

./node_modules/.bin/babel-node script.js

Security Notice: Basing the cookie off an MD5 hash of deterministic data is a bad idea; it's better to use a random token derived from a CSPRNG. See ircmaxell's answer to this question for a more secure approach.

Usually I do something like this:

1. User logs in with 'keep me logged in'
2. Create session
3. Create a cookie called SOMETHING containing: md5(salt+username+ip+salt) and a cookie called somethingElse containing id
4. Store cookie in database
5. User does stuff and leaves ----
6. User returns, check for somethingElse cookie, if it exists, get the old hash from the database for that user, check of the contents of cookie SOMETHING match with the hash from the database, which should also match with a newly calculated hash (for the ip) thus: cookieHash==databaseHash==md5(salt+username+ip+salt), if they do, goto 2, if they don't goto 1

Off course you can use different cookie names etc. also you can change the content of the cookie a bit, just make sure it isn't to easily created. You can for example also create a user_salt when the user is created and also put that in the cookie.

Also you could use sha1 instead of md5 (or pretty much any algorithm)

Javascript solution:

I have successfully attached to existing browser session using this function

webdriver.WebDriver.attachToSession(executor, session_id);

Why not use the PDFMergerUtility of pdfbox?

PDFMergerUtility ut = new PDFMergerUtility();
ut.addSource(...);
ut.addSource(...);
ut.addSource(...);
ut.setDestinationFileName(...);
ut.mergeDocuments();

Just use this script to dynamically backup all databases on the server. Then create batch file according to the article. It is usefull to create two batch files, one for full backup a and one for diff backup. Then Create two tasks in Task Scheduler, one for full and one for diff.

And batch file can look like this:

sqlcmd -S localhost\myDB -Q "EXEC sp_BackupDatabases @backupLocation='c:\Dropbox\backup\DB\', @backupType='F'"  >> c:\Dropbox\backup\DB\full.log 2>&1

and

sqlcmd -S localhost\myDB -Q "EXEC sp_BackupDatabases @backupLocation='c:\Dropbox\backup\DB\', @backupType='D'"  >> c:\Dropbox\backup\DB\diff.log 2>&1

The advantage of this method is that you don't need to change anything if you add new database or delete a database, you don't even need to list the databases in the script. Answer from JohnB is better/simpler for server with one database, this approach is more suitable for multi database servers.

You may call U.difference(lists) method in underscore-java library. I am the maintainer of the project. Live example

import com.github.underscore.U;
import java.util.Arrays;
import java.util.List;

public class Main {
    public static void main(String[] args) {
        List<Integer> list1 = Arrays.asList(1, 2, 3);
        List<Integer> list2 = Arrays.asList(1, 2);
        List<Integer> list3 = U.difference(list1, list2);
        System.out.println(list3);
        // [3]
    }
}

BlogPost.find_each(&:destroy)

From your Activity, just pass in this as the Context for your layout:

ProfileView pv = new ProfileView(this, null, temp, tempPd);

Afterwards you will have a Context in the layout, but you will know it is actually your Activity and you can cast it so that you have what you need:

Activity activity = (Activity) context;

It's a late answer but now there is an easy way. Current version of jquery lets you search if attribute exists. For example

$('[id]')

will give you all the elements if they have id. If you want all spans with id starting with span you can use

$('span[id^="span"]')

What is your output when you do java -version? This will tell you what version the running JVM is.

The Unsupported major.minor version 51.0 error could mean:

• Your server is running a lower Java version then the one used to compile your Servlet and vice versa

Either way, uninstall all JVM runtimes including JDK and download latest and re-install. That should fix any Unsupported major.minor error as you will have the lastest JRE and JDK (Maybe even newer then the one used to compile the Servlet)

See: http://www.java.com/en/download/manual.jsp (7 Update 25 )

and here: http://www.oracle.com/technetwork/java/javase/downloads/index.html (Java Platform (JDK) 7u25)

for the latest version of the JRE and JDK respectively.

EDIT:

Most likely your code was written in Java7 however maybe it was done using Java7update4 and your system is running Java7update3. Thus they both are effectively the same major version but the minor versions differ. Only the larger minor version is backward compatible with the lower minor version.

Edit 2 : If you have more than one jdk installed on your pc. you should check that Apache Tomcat is using the same one (jre) you are compiling your programs with. If you installed a new jdk after installing apache it normally won't select the new version.

You're correct. As others said according to your comments, you probably did not initialize your ArrayList.

My point is different: you claimed that you're checking for duplicates and this is why you call the contains method. Try using HashSet. It should be more efficient - unless you need to keep the order of URLs for any reason.

I liked the idea of checking a list like:

for i in `cat Hostlist`
do  
  ping -c1 -w2 $i | grep "PING" | awk '{print $2,$3}'
done

but that snippet doesn't care if a host is unreachable, so is not a great answer IMHO.

I ran with it and wrote

for i in `cat Hostlist`
do
  ping -c1 -w2 $i >/dev/null 2>&1 ; echo $i $?
done

And I can then handle each accordingly.

Ok guys I found a possible solution to this problem. I realized that joins do not exists in Mongo, that's why first you need to query the user's ids with the role you like, and after that do another query to the profiles document, something like this:

    const exclude: string = '-_id -created_at -gallery -wallet -MaxRequestersPerBooking -active -__v';

  // Get the _ids of users with the role equal to role.
    await User.find({role: role}, {_id: 1, role: 1, name: 1},  function(err, docs) {

        // Map the docs into an array of just the _ids
        var ids = docs.map(function(doc) { return doc._id; });

        // Get the profiles whose users are in that set.
        Profile.find({user: {$in: ids}}, function(err, profiles) {
            // docs contains your answer
            res.json({
                code: 200,
                profiles: profiles,
                page: page
            })
        })
        .select(exclude)
        .populate({
            path: 'user',
            select: '-password -verified -_id -__v'
            // group: { role: "$role"} 
          })
    });

From both long and short youtube urls you can get the embed this way:

$ytarray=explode("/", $videolink);
$ytendstring=end($ytarray);
$ytendarray=explode("?v=", $ytendstring);
$ytendstring=end($ytendarray);
$ytendarray=explode("&", $ytendstring);
$ytcode=$ytendarray[0];
echo "<iframe width=\"420\" height=\"315\" src=\"http://www.youtube.com/embed/$ytcode\" frameborder=\"0\" allowfullscreen></iframe>";

Hope it helps someone

A more general approach would be to set the UIView's appearance's tintColor.

UIColor *myColor = [UIColor purpleColor];
[[UIView appearance] setTintColor:myColor];

Makes sense if you're using many default UI elements.

You have to disable or enable the individual elements. This is how I did it:

$(':input').keydown(function(e){
     var allowTab = true; 
     var id = $(this).attr('name');

     // insert your form fields here -- (:'') is required after
     var inputArr = {username:'', email:'', password:'', address:''}

     // allow or disable the fields in inputArr by changing true / false
     if(id in inputArr) allowTab = false; 

     if(e.keyCode==9 && allowTab==false) e.preventDefault();
});

facing same error while add repository to git hun using git bash on windows

 git remote add origin https://github.com/axaysushir/netflix_page_clone.git

fatal: remote origin already exists.

fatal: remote origin already exists.

 ! [rejected]        master -> master (fetch first)

error: failed to push some refs to 'https://github.com/axaysushir/meditation_app_using_js.git'

Update repository by following command

$ git remote set-url origin https://github.com/axaysushir/netflix_page_clone.git

then add repository using git remote add github instead git remote add origin

$ git remote add github https://github.com/axaysushir/netflix_page_clone.git

And then write following command instead of git push origin master this will upload your repository to github

$ git push github master

ES2017 approach

Object.entries(obj).map(([key, val]) => `${key}=${val}`).join('&')

Well here is an elegant, non-recursive, O(n!) solution:

public static StringBuilder[] permutations(String s) {
        if (s.length() == 0)
            return null;
        int length = fact(s.length());
        StringBuilder[] sb = new StringBuilder[length];
        for (int i = 0; i < length; i++) {
            sb[i] = new StringBuilder();
        }
        for (int i = 0; i < s.length(); i++) {
            char ch = s.charAt(i);
            int times = length / (i + 1);
            for (int j = 0; j < times; j++) {
                for (int k = 0; k < length / times; k++) {
                    sb[j * length / times + k].insert(k, ch);
                }
            }
        }
        return sb;
    }

TL-DR

docker ps --no-trunc and docker inspect CONTAINER provide the entrypoint executed to start the container, along the command passed to, but that may miss some parts such as ${ANY_VAR} because container environment variables are not printed as resolved.

To overcome that, docker inspect CONTAINER has an advantage because it also allow to retrieve separately env variables and their values defined in the container from the Config.Env property.

docker ps and docker inspect provide information about the executed entrypoint and its command. Often, that is a wrapper entrypoint script (.sh) and not the "real" program started by the container. To get information on that, requesting process information with ps or /proc/1/cmdline help.

1) docker ps --no-trunc

It prints the entrypoint and the command executed for all running containers. While it prints the command passed to the entrypoint (if we pass that), it doesn't show value of docker env variables (such as $FOO or ${FOO}).
If our containers use env variables, it may be not enough.

For example, run an alpine container :

docker run --name alpine-example -e MY_VAR=/var alpine:latest sh -c 'ls $MY_VAR'

When use docker -ps such as :

docker ps -a --filter name=alpine-example --no-trunc

It prints :

CONTAINER ID           IMAGE               COMMAND                CREATED             STATUS                     PORTS               NAMES
5b064a6de6d8417...   alpine:latest       "sh -c 'ls $MY_VAR'"   2 minutes ago       Exited (0) 2 minutes ago                       alpine-example

We see the command passed to the entrypoint : sh -c 'ls $MY_VAR' but $MY_VAR is indeed not resolved.

2) docker inspect CONTAINER

When we inspect the alpine-example container :

docker inspect alpine-example | grep -4 Cmd

The command is also there but we don't still see the env variable value :

        "Cmd": [
            "sh",
            "-c",
            "ls $MY_VAR"
        ],

In fact, we could not see interpolated variables with these docker commands.
While as a trade-off, we could display separately both command and env variables for a container with docker inspect :

docker inspect  alpine-example  | grep -4 -E "Cmd|Env"

That prints :

        "Env": [
            "MY_VAR=/var",
            "PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"
        ],
        "Cmd": [
            "sh",
            "-c",
            "ls $MY_VAR"
        ]

A more docker way would be to use the --format flag of docker inspect that allows to specify JSON attributes to render :

docker inspect --format '{{.Name}} {{.Config.Cmd}}  {{ (.Config.Env) }}'  alpine-example

That outputs :

/alpine-example [sh -c ls $MY_VAR]  [MY_VAR=/var PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin]

3) Retrieve the started process from the container itself for running containers

The entrypoint and command executed by docker may be helpful but in some cases, it is not enough because that is "only" a wrapper entrypoint script (.sh) that is responsible to start the real/core process.
For example when I run a Nexus container, the command executed and shown to run the container is "sh -c ${SONATYPE_DIR}/start-nexus-repository-manager.sh".
For PostgreSQL that is "docker-entrypoint.sh postgres".

To get more information, we could execute on a running container docker exec CONTAINER ps aux.
It may print other processes that may not interest us.
To narrow to the initial process launched by the entrypoint, we could do :

docker exec CONTAINER ps -1

I specify 1 because the process executed by the entrypoint is generally the one with the 1 id.

Without ps, we could still find the information in /proc/1/cmdline (in most of Linux distros but not all). For example :

docker exec CONTAINER cat /proc/1/cmdline | sed -e "s/\x00/ /g"; echo    

If we have access to the docker host that started the container, another alternative to get the full command of the process executed by the entrypoint is : : execute ps -PID where PID is the local process created by the Docker daemon to run the container such as :

ps -$(docker container inspect --format '{{.State.Pid}}'  CONTAINER)

User-friendly formatting with docker ps

docker ps --no-trunc is not always easy to read.
Specifying columns to print and in a tabular format may make it better :

docker ps   --no-trunc  --format "table{{.Names}}\t{{.CreatedAt}}\t{{.Command}}"

Create an alias may help :

alias dps='docker ps   --no-trunc  --format "table{{.Names}}\t{{.CreatedAt}}\t{{.Command}}"'

This: "\0" is a string, not a character. A character uses single quotes, like '\0'.

This will do it:

[[NSOperationQueue mainQueue] addOperationWithBlock:^ {

   //Your code goes in here
   NSLog(@"Main Thread Code");

}];

Hope this helps!

if we use the system given action bar following code works fine

getActionBar().setHomeButtonEnabled(true);

@Override
public boolean onMenuItemSelected(int featureId, MenuItem item) {

    int itemId = item.getItemId();
    switch (itemId) {
    case android.R.id.home:
      //do your action here.
        break;

    }

    return true;
}

push() is for arrays, not objects, so use the right data structure.

var data = [];
// ...
data[0] = { "ID": "1", "Status": "Valid" };
data[1] = { "ID": "2", "Status": "Invalid" };
// ...
var tempData = [];
for ( var index=0; index<data.length; index++ ) {
    if ( data[index].Status == "Valid" ) {
        tempData.push( data );
    }
}
data = tempData;

Being aware of the transaction (autocommit, explicit and implicit) handling for your database can save you from having to restore data from a backup.

Transactions control data manipulation statement(s) to ensure they are atomic. Being "atomic" means the transaction either occurs, or it does not. The only way to signal the completion of the transaction to database is by using either a COMMIT or ROLLBACK statement (per ANSI-92, which sadly did not include syntax for creating/beginning a transaction so it is vendor specific). COMMIT applies the changes (if any) made within the transaction. ROLLBACK disregards whatever actions took place within the transaction - highly desirable when an UPDATE/DELETE statement does something unintended.

Typically individual DML (Insert, Update, Delete) statements are performed in an autocommit transaction - they are committed as soon as the statement successfully completes. Which means there's no opportunity to roll back the database to the state prior to the statement having been run in cases like yours. When something goes wrong, the only restoration option available is to reconstruct the data from a backup (providing one exists). In MySQL, autocommit is on by default for InnoDB - MyISAM doesn't support transactions. It can be disabled by using:

SET autocommit = 0

An explicit transaction is when statement(s) are wrapped within an explicitly defined transaction code block - for MySQL, that's START TRANSACTION. It also requires an explicitly made COMMIT or ROLLBACK statement at the end of the transaction. Nested transactions is beyond the scope of this topic.

Implicit transactions are slightly different from explicit ones. Implicit transactions do not require explicity defining a transaction. However, like explicit transactions they require a COMMIT or ROLLBACK statement to be supplied.

Conclusion

Explicit transactions are the most ideal solution - they require a statement, COMMIT or ROLLBACK, to finalize the transaction, and what is happening is clearly stated for others to read should there be a need. Implicit transactions are OK if working with the database interactively, but COMMIT statements should only be specified once results have been tested & thoroughly determined to be valid.

That means you should use:

SET autocommit = 0;

START TRANSACTION;
  UPDATE ...;

...and only use COMMIT; when the results are correct.

That said, UPDATE and DELETE statements typically only return the number of rows affected, not specific details. Convert such statements into SELECT statements & review the results to ensure correctness prior to attempting the UPDATE/DELETE statement.

Addendum

DDL (Data Definition Language) statements are automatically committed - they do not require a COMMIT statement. IE: Table, index, stored procedure, database, and view creation or alteration statements.

I struggled with this myself, and tried Tomik's answer. However, this didn't made the layout to full available width on start, only when you add something to the view.

You'll need to set the LayoutParams.FILL_PARENT when adding the view:

//I'm using actionbarsherlock, but it's the same.
LayoutParams layout = new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT);
getSupportActionBar().setCustomView(overlay, layout); 

This way it completely fills the available space. (You may need to use Tomik's solution too).

This is the hash function that Google uses in production for python 2.5:

def c_mul(a, b):
  return eval(hex((long(a) * b) & (2**64 - 1))[:-1])

def py25hash(self):
  if not self:
    return 0 # empty
  value = ord(self[0]) << 7
  for char in self:
    value = c_mul(1000003, value) ^ ord(char)
  value = value ^ len(self)
  if value == -1:
    value = -2
  if value >= 2**63:
    value -= 2**64
  return value

non recursive approach to convert decimal to hex

def to_hex(dec):

    hex_str = ''
    hex_digits = ('0','1','2','3','4','5','6','7','8','9','A','B','C','D','E','F')
    rem = dec % 16

    while dec >= rem:
        remainder = dec % 16
        quotient = dec / 16
        if quotient == 0:
            hex_str += hex_digits[remainder]
        else:
            hex_str += str(remainder)
        dec = quotient

    return hex_str[::-1] # reverse the string

You could design your class to be immutable (Effective Java 2nd Ed. has a great section on this, Item 15: Minimize mutability) and make sure upon construction that no nulls are possible (and use the null object pattern if needed). Then you can skip all those checks and safely assume the values are not null.

You could create a list of Object like List<Object> list = new ArrayList<Object>(). As all classes implementation extends implicit or explicit from java.lang.Object class, this list can hold any object, including instances of Employee, Integer, String etc.

When you retrieve an element from this list, you will be retrieving an Object and no longer an Employee, meaning you need to perform a explicit cast in this case as follows:

List<Object> list = new ArrayList<Object>();
list.add("String");
list.add(Integer.valueOf(1));
list.add(new Employee());

Object retrievedObject = list.get(2);
Employee employee = (Employee)list.get(2); // explicit cast

A shorthand of the previous solutions is

var myDate = +new Date("2012-02-10T13:19:11+0000");

It does an on the fly type conversion and directly outputs date in millisecond format.

Another way is also using parse method of Date util which only outputs EPOCH time in milliseconds.

var myDate = Date.parse("2012-02-10T13:19:11+0000");

You can use a datetime field and set it's default value to GetDate().

CREATE TABLE [dbo].[Test](
    [TimeStamp] [datetime] NOT NULL CONSTRAINT [DF_Test_TimeStamp] DEFAULT (GetDate()),
    [Foo] [varchar](50) NOT NULL
) ON [PRIMARY]

The problem is that there is an in-browser print dialogue within the popup window. If you call window.close() immediately then the dialogue is not seen by the user. The user needs to click "Print" within the dialogue. This is not the same as on other browsers where the print dialogue is part of the OS, and blocks the window.close() until dismissed - on Chrome, it's part of Chrome, not the OS.

This is the code I used, in a little popup window that is created by the parent window:

var is_chrome = function () { return Boolean(window.chrome); }
window.onload = function() {
    if(is_chrome){
        /*
         * These 2 lines are here because as usual, for other browsers,
         * the window is a tiny 100x100 box that the user will barely see.
         * On Chrome, it needs to be big enough for the dialogue to be read
         * (NB, it also includes a page preview).
        */
        window.moveTo(0,0);
        window.resizeTo(640, 480);

        // This line causes the print dialogue to appear, as usual:
        window.print();

        /*
         * This setTimeout isn't fired until after .print() has finished
         * or the dialogue is closed/cancelled.
         * It doesn't need to be a big pause, 500ms seems OK.
        */
        setTimeout(function(){
            window.close();
        }, 500);
    } else {
        // For other browsers we can do things more briefly:
        window.print();
        window.close();
    }
}

    String start_dt = "2011-01-01"; // Input String

    SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd"); // Existing Pattern
    Date getStartDt = formatter.parse(start_dt); //Returns Date Format according to existing pattern

    SimpleDateFormat simpleDateFormat = new SimpleDateFormat("MM-dd-yyyy");// New Pattern
    String formattedDate = simpleDateFormat.format(getStartDt); // Format given String to new pattern

    System.out.println(formattedDate); //outputs: 01-01-2011

The way you are trying to do it is called LBYL (look before you leap), since you are checking conditions before trying to increment your value.

The other approach is called EAFP (easier to ask forgiveness then permission). In that case, you would just try the operation (increment the value). If it fails, you catch the exception and set the value to 1. This is a slightly more Pythonic way to do it (IMO).

For Mapping Composite primary key using Entity framework we can use two approaches.

1) By Overriding the OnModelCreating() Method

For ex: I have the model class named VehicleFeature as shown below.

public class VehicleFeature
{
    public int VehicleId { get; set; }
    public int FeatureId{get;set;}
    public Vehicle Vehicle{get;set;}
    public Feature Feature{get;set;}
}

The Code in my DBContext would be like ,

public class VegaDbContext : DbContext
{
    public DbSet<Make> Makes{get;set;}

    public DbSet<Feature> Features{get;set;}
    public VegaDbContext(DbContextOptions<VegaDbContext> options):base(options)        
    {           

    }
    // we override the OnModelCreating method here.
    protected override void OnModelCreating(ModelBuilder modelBuilder)
    {
        modelBuilder.Entity<VehicleFeature>().HasKey(vf=> new {vf.VehicleId, vf.FeatureId});
    }
}

2) By Data Annotations.

public class VehicleFeature
{
    [DatabaseGenerated(DatabaseGeneratedOption.Identity)]  
    [Key]
    public int VehicleId { get; set; }
    [DatabaseGenerated(DatabaseGeneratedOption.Identity)]   
    [Key]
    public int FeatureId{get;set;}
    public Vehicle Vehicle{get;set;}
    public Feature Feature{get;set;}
}

2) How to add a composite unique key using EF 6 Fluent Api?

Here's one sample: http://jsfiddle.net/CUUfb/1/

After Jenkins is installed just run sudo cat /var/lib/jenkins/secrets/initialAdminPassword.

In the Jenkins login page:

There is now a beta available of Google Maps KML Importing Utility.

It is part of the Google Maps Android API Utility Library. As documented it allows loading KML files from streams

KmlLayer layer = new KmlLayer(getMap(), kmlInputStream, getApplicationContext());

or local resources

KmlLayer layer = new KmlLayer(getMap(), R.raw.kmlFile, getApplicationContext());

After you have created a KmlLayer, call addLayerToMap() to add the imported data onto the map.

layer.addLayerToMap();

Do you need the pipe?

echo -ne "$MENU"
read NUMBER

If you are using Lodash library below is the way to set a dynamic variable in the angular scope.

To set the value in the angular scope.

_.set($scope, the_string, 'life.meaning')

To get the value from the angular scope.

_.get($scope, 'life.meaning')

It is possible to avoid constructor annotations with jdk8 where optionally the compiler will introduce metadata with the names of the constructor parameters. Then with jackson-module-parameter-names module Jackson can use this constructor. You can see an example at post Jackson without annotations

• The Java™ Tutorials - Obtaining Names of Method Parameters

if statement is not vectorized. For vectorized if statements you should use ifelse. In your case it is sufficient to write

w <- function(a){
if (any(a>0)){
  a/sum(a)
}
  else 1
}

or a short vectorised version

ifelse(a > 0, a/sum(a), 1)

It depends on which do you want to use, because first function gives output vector of length 1 (in else part) and ifelse gives output vector of length equal to length of a.

I had a similar problem and it turned out the issue was having both versions 6 & 7 of OpenJDK. The answer comes from r-senior on ubuntu forums (http://ubuntuforums.org/showthread.php?t=1977619) --- just uninstall version 6:

sudo apt-get remove openjdk-6-*

make sure that JAVA_HOME and CLASSPATH aren't set to anything since that isn't actually the problem.

If your simple test page is located on other protocol/domain/port than your hello world node.js example you are doing cross-domain requests and violating same origin policy therefore your jQuery ajax calls (get and load) are failing silently. To get this working cross-domain you should use JSONP based format. For example node.js code:

var http = require('http');

http.createServer(function (req, res) {
    console.log('request received');
    res.writeHead(200, {'Content-Type': 'text/plain'});
    res.end('_testcb(\'{"message": "Hello world!"}\')');
}).listen(8124);

and client side JavaScript/jQuery:

$(document).ready(function() {
    $.ajax({
        url: 'http://192.168.1.103:8124/',
        dataType: "jsonp",
        jsonpCallback: "_testcb",
        cache: false,
        timeout: 5000,
        success: function(data) {
            $("#test").append(data);
        },
        error: function(jqXHR, textStatus, errorThrown) {
            alert('error ' + textStatus + " " + errorThrown);
        }
    });
});

There are also other ways how to get this working, for example by setting up reverse proxy or build your web application entirely with framework like express.

Swift 3.0 solution:

let string = array.joined(separator: " ")

Static Typing: The languages such as Java and Scala are static typed.

The variables have to be defined and initialized before they are used in a code.

for ex. int x; x = 10;

System.out.println(x);

Dynamic Typing: Perl is an dynamic typed language.

Variables need not be initialized before they are used in code.

y=10; use this variable in the later part of code

The goal of an assertion in Python is to inform developers about unrecoverable errors in a program.

Assertions are not intended to signal expected error conditions, like “file not found”, where a user can take corrective action (or just try again).

Another way to look at it is to say that assertions are internal self-checks in your code. They work by declaring some conditions as impossible in your code. If these conditions don’t hold that means there’s a bug in the program.

If your program is bug-free, these conditions will never occur. But if one of them does occur the program will crash with an assertion error telling you exactly which “impossible” condition was triggered. This makes it much easier to track down and fix bugs in your programs.

Here’s a summary from a tutorial on Python’s assertions I wrote:

Python’s assert statement is a debugging aid, not a mechanism for handling run-time errors. The goal of using assertions is to let developers find the likely root cause of a bug more quickly. An assertion error should never be raised unless there’s a bug in your program.

You can expose the service in two different endpoints. the SOAP one can use the binding that support SOAP e.g. basicHttpBinding, the RESTful one can use the webHttpBinding. I assume your REST service will be in JSON, in that case, you need to configure the two endpoints with the following behaviour configuration

<endpointBehaviors>
  <behavior name="jsonBehavior">
    <enableWebScript/>
  </behavior>
</endpointBehaviors>

An example of endpoint configuration in your scenario is

<services>
  <service name="TestService">
    <endpoint address="soap" binding="basicHttpBinding" contract="ITestService"/>
    <endpoint address="json" binding="webHttpBinding"  behaviorConfiguration="jsonBehavior" contract="ITestService"/>
  </service>
</services>

so, the service will be available at

• http://www.example.com/soap
• http://www.example.com/json

Apply [WebGet] to the operation contract to make it RESTful. e.g.

public interface ITestService
{
   [OperationContract]
   [WebGet]
   string HelloWorld(string text)
}

Note, if the REST service is not in JSON, parameters of the operations can not contain complex type.

Reply to the post for SOAP and RESTful POX(XML)

For plain old XML as return format, this is an example that would work both for SOAP and XML.

[ServiceContract(Namespace = "http://test")]
public interface ITestService
{
    [OperationContract]
    [WebGet(UriTemplate = "accounts/{id}")]
    Account[] GetAccount(string id);
}

POX behavior for REST Plain Old XML

<behavior name="poxBehavior">
  <webHttp/>
</behavior>

Endpoints

<services>
  <service name="TestService">
    <endpoint address="soap" binding="basicHttpBinding" contract="ITestService"/>
    <endpoint address="xml" binding="webHttpBinding"  behaviorConfiguration="poxBehavior" contract="ITestService"/>
  </service>
</services>

Service will be available at

• http://www.example.com/soap
• http://www.example.com/xml

REST request try it in browser,

http://www.example.com/xml/accounts/A123

SOAP request client endpoint configuration for SOAP service after adding the service reference,

  <client>
    <endpoint address="http://www.example.com/soap" binding="basicHttpBinding"
      contract="ITestService" name="BasicHttpBinding_ITestService" />
  </client>

in C#

TestServiceClient client = new TestServiceClient();
client.GetAccount("A123");

Another way of doing it is to expose two different service contract and each one with specific configuration. This may generate some duplicates at code level, however at the end of the day, you want to make it working.

I resolved it like this:

<% @user.errors.each do |attr, msg| %>
  <li>
    <%= @user.errors.full_messages_for(attr).first if @user.errors[attr].first == msg %>
  </li>
<% end %>

This way you are using the locales for the error messages.

How do I run an executable JAR file? If you have a jar file called Example.jar, follow these rules:

Open a notepad.exe.
Write : java -jar Example.jar.
Save it with the extension .bat.
Copy it to the directory which has the .jar file.
Double click it to run your .jar file.

Since .Net 3.5 you can use DefaultIfEmpty() passing the default value as an argument. Something like one of the followings ways:

int max = (from e in context.Table where e.Year == year select e.RecordNumber).DefaultIfEmpty(0).Max();
DateTime maxDate = (from e in context.Table where e.Year == year select e.StartDate ?? DateTime.MinValue).DefaultIfEmpty(DateTime.MinValue).Max();

The first one is allowed when you query a NOT NULL column and the second one is the way a used it to query a NULLABLE column. If you use DefaultIfEmpty() without arguments the default value will be that defined to the type of your output, as you can see in the Default Values Table .

The resulting SELECT will not be so elegant but it's acceptable.

Hope it helps.

If I understand you correctly, you have a utf-8 encoded byte-string in your code.

Converting a byte-string to a unicode string is known as decoding (unicode -> byte-string is encoding).

You do that by using the unicode function or the decode method. Either:

unicodestr = unicode(bytestr, encoding)
unicodestr = unicode(bytestr, "utf-8")

Or:

unicodestr = bytestr.decode(encoding)
unicodestr = bytestr.decode("utf-8")

Whether null char is allowed or not really depends on base64 codec in question. Given vagueness of Base64 standard (there is no authoritative exact specification), many implementations would just ignore it as white space. And then others can flag it as a problem. And buggiest ones wouldn't notice and would happily try decoding it... :-/

But it sounds c# implementation does not like it (which is one valid approach) so if removing it helps, that should be done.

One minor additional comment: UTF-8 is not a requirement, ISO-8859-x aka Latin-x, and 7-bit Ascii would work as well. This because Base64 was specifically designed to only use 7-bit subset which works with all 7-bit ascii compatible encodings.

This is a bit of an open ended question since screen sizes are changing all the time and what might have been correct two years ago would likely be out of date now.

I use Twitter Bootstrap 3 at present and it uses a fluid grid system designed to work at sizes ranging from mobile/very small all the way up to the huge wide screen monitors that are now available.

Currently the upper default in BS3 is 1200px which translates to a container width of 1144px after taking account of margins and padding of the grids elements.

In my experience, modern designers are working to a width of around 1366px for desktop. All recent designs I've been given to implement have been 1366px.

Note also that you can customise the BS3 grid quite heavily. For example we will use a 32 column grid with 4px gutter in our sites/designs going forwards.

Ultimately the decision on page width needs to be made based on your website analytics and the screen sizes that your visitors typically use.

Update

The solution below has a "SEO friendlier" version:

function hyphenize($string) {
    $dict = array(
        "I'm"      => "I am",
        "thier"    => "their",
        // Add your own replacements here
    );
    return strtolower(
        preg_replace(
          array( '#[\\s-]+#', '#[^A-Za-z0-9. -]+#' ),
          array( '-', '' ),
          // the full cleanString() can be downloaded from http://www.unexpectedit.com/php/php-clean-string-of-utf8-chars-convert-to-similar-ascii-char
          cleanString(
              str_replace( // preg_replace can be used to support more complicated replacements
                  array_keys($dict),
                  array_values($dict),
                  urldecode($string)
              )
          )
        )
    );
}

function cleanString($text) {
    $utf8 = array(
        '/[áàâãªä]/u'   =>   'a',
        '/[ÁÀÂÃÄ]/u'    =>   'A',
        '/[ÍÌÎÏ]/u'     =>   'I',
        '/[íìîï]/u'     =>   'i',
        '/[éèêë]/u'     =>   'e',
        '/[ÉÈÊË]/u'     =>   'E',
        '/[óòôõºö]/u'   =>   'o',
        '/[ÓÒÔÕÖ]/u'    =>   'O',
        '/[úùûü]/u'     =>   'u',
        '/[ÚÙÛÜ]/u'     =>   'U',
        '/ç/'           =>   'c',
        '/Ç/'           =>   'C',
        '/ñ/'           =>   'n',
        '/Ñ/'           =>   'N',
        '/–/'           =>   '-', // UTF-8 hyphen to "normal" hyphen
        '/[’‘‹›‚]/u'    =>   ' ', // Literally a single quote
        '/[“”«»„]/u'    =>   ' ', // Double quote
        '/ /'           =>   ' ', // nonbreaking space (equiv. to 0x160)
    );
    return preg_replace(array_keys($utf8), array_values($utf8), $text);
}

The rationale for the above functions (which I find way inefficient - the one below is better) is that a service that shall not be named apparently ran spelling checks and keyword recognition on the URLs.

After losing a long time on a customer's paranoias, I found out they were not imagining things after all -- their SEO experts [I am definitely not one] reported that, say, converting "Viaggi Economy Perù" to viaggi-economy-peru "behaved better" than viaggi-economy-per (the previous "cleaning" removed UTF8 characters; Bogotà became bogot, Medellìn became medelln and so on).

There were also some common misspellings that seemed to influence the results, and the only explanation that made sense to me is that our URL were being unpacked, the words singled out, and used to drive God knows what ranking algorithms. And those algorithms apparently had been fed with UTF8-cleaned strings, so that "Perù" became "Peru" instead of "Per". "Per" did not match and sort of took it in the neck.

In order to both keep UTF8 characters and replace some misspellings, the faster function below became the more accurate (?) function above. $dict needs to be hand tailored, of course.

Previous answer

A simple approach:

// Remove all characters except A-Z, a-z, 0-9, dots, hyphens and spaces
// Note that the hyphen must go last not to be confused with a range (A-Z)
// and the dot, NOT being special (I know. My life was a lie), is NOT escaped

$str = preg_replace('/[^A-Za-z0-9. -]/', '', $str);

// Replace sequences of spaces with hyphen
$str = preg_replace('/  */', '-', $str);

// The above means "a space, followed by a space repeated zero or more times"
// (should be equivalent to / +/)

// You may also want to try this alternative:
$str = preg_replace('/\\s+/', '-', $str);

// where \s+ means "zero or more whitespaces" (a space is not necessarily the
// same as a whitespace) just to be sure and include everything

Note that you might have to first urldecode() the URL, since %20 and + both are actually spaces - I mean, if you have "Never%20gonna%20give%20you%20up" you want it to become Never-gonna-give-you-up, not Never20gonna20give20you20up . You might not need it, but I thought I'd mention the possibility.

So the finished function along with test cases:

function hyphenize($string) {
    return 
    ## strtolower(
          preg_replace(
            array('#[\\s-]+#', '#[^A-Za-z0-9. -]+#'),
            array('-', ''),
        ##     cleanString(
              urldecode($string)
        ##     )
        )
    ## )
    ;
}

print implode("\n", array_map(
    function($s) {
            return $s . ' becomes ' . hyphenize($s);
    },
    array(
    'Never%20gonna%20give%20you%20up',
    "I'm not the man I was",
    "'Légeresse', dit sa majesté",
    )));


Never%20gonna%20give%20you%20up    becomes  never-gonna-give-you-up
I'm not the man I was              becomes  im-not-the-man-I-was
'Légeresse', dit sa majesté        becomes  legeresse-dit-sa-majeste

To handle UTF-8 I used a cleanString implementation found online (link broken since, but a stripped down copy with all the not-too-esoteric UTF8 characters is at the beginning of the answer; it's also easy to add more characters to it if you need) that converts UTF8 characters to normal characters, thus preserving the word "look" as much as possible. It could be simplified and wrapped inside the function here for performance.

The function above also implements converting to lowercase - but that's a taste. The code to do so has been commented out.

look at String.indexOf and String.substring.

Make sure you check for -1 for indexOf.

You can invoke private method with reflection. Modifying the last bit of the posted code:

Method method = object.getClass().getDeclaredMethod(methodName);
method.setAccessible(true);
Object r = method.invoke(object);

There are a couple of caveats. First, getDeclaredMethod will only find method declared in the current Class, not inherited from supertypes. So, traverse up the concrete class hierarchy if necessary. Second, a SecurityManager can prevent use of the setAccessible method. So, it may need to run as a PrivilegedAction (using AccessController or Subject).

There's not much of one in everyday work.

However, according to the documentation for both functions (accessed by putting a ? before the function name and hitting enter), require is used inside functions, as it outputs a warning and continues if the package is not found, whereas library will throw an error.

I am using Google API for .Net, but no doubt you can find the same way to obtain this information using other version of API. As user872858 mentioned, scope userinfo.profile has been deprecated (google article) .

To obtain user profile info I use following code (re-written part from google's example):

IAuthorizationCodeFlow flow = new GoogleAuthorizationCodeFlow(
                                  new GoogleAuthorizationCodeFlow.Initializer
                                      {
                                            ClientSecrets = Secrets,
                                            Scopes = new[] { PlusService.Scope.PlusLogin,"https://www.googleapis.com/auth/plus.profile.emails.read"  }
                                       });    
TokenResponse _token = flow.ExchangeCodeForTokenAsync("", code, "postmessage", 
                              CancellationToken.None).Result;

                    // Create an authorization state from the returned token.
                    context.Session["authState"] = _token;

                    // Get tokeninfo for the access token if you want to verify.
                    Oauth2Service service = new Oauth2Service(
                     new Google.Apis.Services.BaseClientService.Initializer());
                    Oauth2Service.TokeninfoRequest request = service.Tokeninfo();
                    request.AccessToken = _token.AccessToken;
                    Tokeninfo info = request.Execute();
                    if (info.VerifiedEmail.HasValue && info.VerifiedEmail.Value)
                    {
                        flow = new GoogleAuthorizationCodeFlow(
                                    new GoogleAuthorizationCodeFlow.Initializer
                                         {
                                             ClientSecrets = Secrets,
                                             Scopes = new[] { PlusService.Scope.PlusLogin }
                                          });

                        UserCredential credential = new UserCredential(flow, 
                                                              "me", _token);
                        _token = credential.Token;
                        _ps = new PlusService(
                              new Google.Apis.Services.BaseClientService.Initializer()
                               {
                                   ApplicationName = "Your app name",
                                   HttpClientInitializer = credential
                               });
                        Person userProfile = _ps.People.Get("me").Execute();
                    }

Than, you can access almost anything using userProfile.

UPDATE: To get this code working you have to use appropriate scopes on google sign in button. For example my button:

     <button class="g-signin"
             data-scope="https://www.googleapis.com/auth/plus.login https://www.googleapis.com/auth/plus.profile.emails.read"
             data-clientid="646361778467-nb2uipj05c4adlk0vo66k96bv8inqles.apps.googleusercontent.com"
             data-accesstype="offline"
             data-redirecturi="postmessage"
             data-theme="dark"
             data-callback="onSignInCallback"
             data-cookiepolicy="single_host_origin"
             data-width="iconOnly">
     </button>

Here is an example from my code (for threaded pool, but just change class name and you'll have process pool):

def execute_run(rp): 
   ... do something 

pool = ThreadPoolExecutor(6)
for mat in TESTED_MATERIAL:
    for en in TESTED_ENERGIES:
        for ecut in TESTED_E_CUT:
            rp = RunParams(
                simulations, DEST_DIR,
                PARTICLE, mat, 960, 0.125, ecut, en
            )
            pool.submit(execute_run, rp)
pool.join()

Basically:

• pool = ThreadPoolExecutor(6) creates a pool for 6 threads
• Then you have bunch of for's that add tasks to the pool
• pool.submit(execute_run, rp) adds a task to pool, first arogument is a function called in in a thread/process, rest of the arguments are passed to the called function.
• pool.join waits until all tasks are done.

An elegant way to move your file to an nonexistent directory is to create the following extension to native FileInfo class:

public static class FileInfoExtension
{
    //second parameter is need to avoid collision with native MoveTo
    public static void MoveTo(this FileInfo file, string destination, bool autoCreateDirectory) { 

        if (autoCreateDirectory)
        {
            var destinationDirectory = new DirectoryInfo(Path.GetDirectoryName(destination));

            if (!destinationDirectory.Exists)
                destinationDirectory.Create();
        }

        file.MoveTo(destination);
    }
}

Then use brand new MoveTo extension:

 using <namespace of FileInfoExtension>;
 ...
 new FileInfo("some path")
     .MoveTo("target path",true);

Check Methods extension documentation.

I think the variable should be in the same block:

@{bool isUserConnected = string.IsNullOrEmpty(Model.CreatorFullName);
    if (isUserConnected)
    { // meaning that the viewing user has not been saved
        <div>
            <div> click to join us </div>
            <a id="login" href="javascript:void(0);" style="display: inline; ">join</a>
        </div>
    }
    }

'SELECT * FROM Employ where number = ' + parseInt(val, 10) + ';'

For example, if val is "10" then this will end up building the string:

"SELECT * FROM Employ where number = 10;"

True, there is no vivid and unambiguous way to declare a single-value variable, what you can do is

with myVar as (select "any value really")

then, to get access to the value stored in this construction, you do

(select * from myVar)

for example

with var as (select 123)    
... where id = (select * from var)

where stateb is List'' bucket is a two dimensional array

statesb= IntStream.of(bucket[j-1]).boxed().collect(Collectors.toList());

with import java.util.stream.IntStream;

This doesn't direcly answer your question, but if you are using innerHTML in order to write text within an element and you ran into encoding issues, just use textContent, i.e.:

var s = "Foo 'bar' baz <qux>";

var element = document.getElementById('foo');
element.textContent = s;

// <div id="foo">Foo 'bar' baz <qux></div>

For me reinstalling and then upgrading the pip worked.

1. Reinstall pip by using below command or following link How do I install pip on macOS or OS X?

   curl https://bootstrap.pypa.io/get-pip.py -o - | python

2. Upgrade pip after it's installed

   pip install -U pip

First thing I would try is to get a bit more information on the error - that's a pretty generic message.

You could enable remote errors as per the error message and replicate the error for more information:

Enable remote errors.

Or check the Report Server error logs to see what error was logged.

%programfiles%\Microsoft SQL Server\<SQL Server Instance>\Reporting Services\LogFiles\

The next step would be to connect as the Data Source user to the database, run any code/stored procedures that the report is using with the same parameters you're using when running the report, and see if any errors occur.

Tom if you have existing array you can convert that array to object and use it like this:

$r = (object) $MyQueryResult;
echo $r->key;

You can use this and then you can add just a class form from bootstrap. ^{(does not matter which version)}

<div class="form-group">
 <label >Begin voorverkoop periode</label>
 <input type="date" name="bday" max="3000-12-31" 
        min="1000-01-01" class="form-control">
</div>
<div class="form-group">
 <label >Einde voorverkoop periode</label>
 <input type="date" name="bday" min="1000-01-01"
        max="3000-12-31" class="form-control">
</div>

You're better off making two selects and showing one while hiding the other.

It's easier, and adding options to selects with your method will not work in IE8 (if you care).

If you use any(lst) you see that lst is the iterable, which is a list of some items. If it contained [0, False, '', 0.0, [], {}, None] (which all have boolean values of False) then any(lst) would be False. If lst also contained any of the following [-1, True, "X", 0.00001] (all of which evaluate to True) then any(lst) would be True.

In the code you posted, x > 0 for x in lst, this is a different kind of iterable, called a generator expression. Before generator expressions were added to Python, you would have created a list comprehension, which looks very similar, but with surrounding []'s: [x > 0 for x in lst]. From the lst containing [-1, -2, 10, -4, 20], you would get this comprehended list: [False, False, True, False, True]. This internal value would then get passed to the any function, which would return True, since there is at least one True value.

But with generator expressions, Python no longer has to create that internal list of True(s) and False(s), the values will be generated as the any function iterates through the values generated one at a time by the generator expression. And, since any short-circuits, it will stop iterating as soon as it sees the first True value. This would be especially handy if you created lst using something like lst = range(-1,int(1e9)) (or xrange if you are using Python2.x). Even though this expression will generate over a billion entries, any only has to go as far as the third entry when it gets to 1, which evaluates True for x>0, and so any can return True.

If you had created a list comprehension, Python would first have had to create the billion-element list in memory, and then pass that to any. But by using a generator expression, you can have Python's builtin functions like any and all break out early, as soon as a True or False value is seen.

For links generated in a JSP with custom tags, I had to use

<%@ page session="false" %>

in the JSP

AND

request.getSession().invalidate();

in the Struts action

This worked for me. If you using rvm and brew:

rvm remove 1.9.3
brew install openssl
rvm install 1.9.3 --with-openssl-dir=`brew --prefix openssl`

I wanted a text field that only allowed integers. Here's what I ended up with (using info from here and elsewhere):

Create integer number formatter (in UIApplicationDelegate so it can be reused):

@property (nonatomic, retain) NSNumberFormatter *integerNumberFormatter;

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    // Create and configure an NSNumberFormatter for integers
    integerNumberFormatter = [[NSNumberFormatter alloc] init];
    [integerNumberFormatter setMaximumFractionDigits:0];

    return YES;
}

Use filter in UITextFieldDelegate:

@interface MyTableViewController : UITableViewController <UITextFieldDelegate> {
    ictAppDelegate *appDelegate;
}

- (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string {
    // Make sure the proposed string is a number
    NSNumberFormatter *inf = [appDelegate integerNumberFormatter];
    NSString* proposedString = [textField.text stringByReplacingCharactersInRange:range withString:string];
    NSNumber *proposedNumber = [inf numberFromString:proposedString];
    if (proposedNumber) {
        // Make sure the proposed number is an integer
        NSString *integerString = [inf stringFromNumber:proposedNumber];
        if ([integerString isEqualToString:proposedString]) {
            // proposed string is an integer
            return YES;
        }
    }

    // Warn the user we're rejecting the change
    AudioServicesPlayAlertSound(kSystemSoundID_Vibrate);
    return NO;
}

you can set maxlength with jquery which is very fast

jQuery(document).ready(function($){ //fire on DOM ready
 setformfieldsize(jQuery('#comment'), 50, 'charsremain')
})

If all you want to do is run your Python Script on a windows computer that has the Python Interpreter installed, converting the extension of your saved script from '.py' to '.pyw' should do the trick.

But if you're using py2exe to convert your script into a standalone application that would run on any windows machine, you will need to make the following changes to your 'setup.py' file.

The following example is of a simple python-GUI made using Tkinter:

from distutils.core import setup
import py2exe
setup (console = ['tkinter_example.pyw'],
       options = { 'py2exe' : {'packages':['Tkinter']}})

Change "console" in the code above to "windows"..

from distutils.core import setup
import py2exe
setup (windows = ['tkinter_example.pyw'],
       options = { 'py2exe' : {'packages':['Tkinter']}})

This will only open the Tkinter generated GUI and no console window.

In Python 2.x this is not guaranteed as it is possible for True and False to be reassigned. However, even if this happens, boolean True and boolean False are still properly returned for comparisons.

In Python 3.x True and False are keywords and will always be equal to 1 and 0.

Under normal circumstances in Python 2, and always in Python 3:

False object is of type bool which is a subclass of int:

object
   |
 int
   |
 bool

It is the only reason why in your example, ['zero', 'one'][False] does work. It would not work with an object which is not a subclass of integer, because list indexing only works with integers, or objects that define a __index__ method (thanks mark-dickinson).

Edit:

It is true of the current python version, and of that of Python 3. The docs for python 2 and the docs for Python 3 both say:

There are two types of integers: [...] Integers (int) [...] Booleans (bool)

and in the boolean subsection:

Booleans: These represent the truth values False and True [...] Boolean values behave like the values 0 and 1, respectively, in almost all contexts, the exception being that when converted to a string, the strings "False" or "True" are returned, respectively.

There is also, for Python 2:

In numeric contexts (for example when used as the argument to an arithmetic operator), they [False and True] behave like the integers 0 and 1, respectively.

So booleans are explicitly considered as integers in Python 2 and 3.

So you're safe until Python 4 comes along. ;-)

I tried several solutions and here is the simplest I personally found.
Dan pointed out in the comments that the original post belongs to Oleg Sych—thanks, Oleg!

Here are the instructions:

1. Add an XML file for each configuration to the project.

Typically you will have Debug and Release configurations so name your files App.Debug.config and App.Release.config. In my project, I created a configuration for each kind of environment, so you might want to experiment with that.

2. Unload project and open .csproj file for editing

Visual Studio allows you to edit .csproj files right in the editor—you just need to unload the project first. Then right-click on it and select Edit <ProjectName>.csproj.

3. Bind App.*.config files to main App.config

Find the project file section that contains all App.config and App.*.config references. You'll notice their build actions are set to None:

<None Include="App.config" />
<None Include="App.Debug.config" />
<None Include="App.Release.config" />

First, set build action for all of them to Content.
Next, make all configuration-specific files dependant on the main App.config so Visual Studio groups them like it does designer and code-behind files.

Replace XML above with the one below:

<Content Include="App.config" />
<Content Include="App.Debug.config" >
  <DependentUpon>App.config</DependentUpon>
</Content>
<Content Include="App.Release.config" >
  <DependentUpon>App.config</DependentUpon>
</Content>

4. Activate transformations magic (only necessary for Visual Studio versions pre VS2017)

In the end of file after

<Import Project="$(MSBuildToolsPath)\Microsoft.CSharp.targets" />

and before final

</Project>

insert the following XML:

  <UsingTask TaskName="TransformXml" AssemblyFile="$(MSBuildExtensionsPath)\Microsoft\VisualStudio\v$(VisualStudioVersion)\Web\Microsoft.Web.Publishing.Tasks.dll" />
  <Target Name="CoreCompile" Condition="exists('app.$(Configuration).config')">
    <!-- Generate transformed app config in the intermediate directory -->
    <TransformXml Source="app.config" Destination="$(IntermediateOutputPath)$(TargetFileName).config" Transform="app.$(Configuration).config" />
    <!-- Force build process to use the transformed configuration file from now on. -->
    <ItemGroup>
      <AppConfigWithTargetPath Remove="app.config" />
      <AppConfigWithTargetPath Include="$(IntermediateOutputPath)$(TargetFileName).config">
        <TargetPath>$(TargetFileName).config</TargetPath>
      </AppConfigWithTargetPath>
    </ItemGroup>
  </Target>

Now you can reload the project, build it and enjoy App.config transformations!

FYI

Make sure that your App.*.config files have the right setup like this:

<?xml version="1.0" encoding="utf-8"?>
<configuration xmlns:xdt="http://schemas.microsoft.com/XML-Document-Transform">
     <!--magic transformations here-->
</configuration>

Here a CSS animation fork of jezzipin's Solution, to seperate code from styling.

JS:

$(window).on("scroll touchmove", function () {
  $('#header_nav').toggleClass('tiny', $(document).scrollTop() > 0);
});

CSS:

.header {
  width:100%;
  height:100px;
  background: #26b;
  color: #fff;
  position:fixed;
  top:0;
  left:0;
  transition: height 500ms, background 500ms;
}
.header.tiny {
  height:40px;
  background: #aaa;
}

http://jsfiddle.net/sinky/S8Fnq/

On scroll/touchmove the css class "tiny" is set to "#header_nav" if "$(document).scrollTop()" is greater than 0.

CSS transition attribute animates the "height" and "background" attribute nicely.

AsyncTask have four methods..

onPreExecute  -- for doing something before calling background task in Async

doInBackground  -- operation/Task to do in Background

onProgressUpdate  -- it is for progress Update

onPostExecute  -- this method calls after asyncTask return from doInBackground.

you can call your work on onPostExecute() it calls after returning from doInBackground()

onPostExecute is what you need to Implement.

Java 5+ has all the tools you need for this kind of thing. You will want to:

1. Put all your Producers in one ExecutorService;
2. Put all your Consumers in another ExecutorService;
3. If necessary, communicate between the two using a BlockingQueue.

I say "if necessary" for (3) because from my experience it's an unnecessary step. All you do is submit new tasks to the consumer executor service. So:

final ExecutorService producers = Executors.newFixedThreadPool(100);
final ExecutorService consumers = Executors.newFixedThreadPool(100);
while (/* has more work */) {
  producers.submit(...);
}
producers.shutdown();
producers.awaitTermination(Long.MAX_VALUE, TimeUnit.NANOSECONDS);
consumers.shutdown();
consumers.awaitTermination(Long.MAX_VALUE, TimeUnit.NANOSECONDS);

So the producers submit directly to consumers.

import operator
sorted_x = sorted(x, key=operator.attrgetter('score'))

if you want to sort x in-place, you can also:

x.sort(key=operator.attrgetter('score'))

You're in luck bud...I had the same issue but had more tech knowledge on the matter and was able to determine that it was a mod_sec issue that hostgator has to fix/whitelist on their own. You cannot do it yourself. Simply ask the hostgator tech to check mod_sec settings on your server.

Enjoy your fixed issue ;D

Try and run the following command:

ALTER TABLE `investments` 
MODIFY created_at TIMESTAMP 
DEFAULT CURRENT_TIMESTAMP 
NOT NULL;

and

ALTER TABLE `investments` 
MODIFY updated_at TIMESTAMP 
DEFAULT CURRENT_TIMESTAMP 
NOT NULL;

The reason you are getting this error is because you are not setting a default value for the created_at and updated_at fields. MySQL is not accepting your command since the values for these columns cannot be null.

$('#cloneDiv').click(function(){


  // get the last DIV which ID starts with ^= "klon"
  var $div = $('div[id^="klon"]:last');

  // Read the Number from that DIV's ID (i.e: 3 from "klon3")
  // And increment that number by 1
  var num = parseInt( $div.prop("id").match(/\d+/g), 10 ) +1;

  // Clone it and assign the new ID (i.e: from num 4 to ID "klon4")
  var $klon = $div.clone().prop('id', 'klon'+num );

  // Finally insert $klon wherever you want
  $div.after( $klon.text('klon'+num) );

});

xargs on MacOS doesn't have -d option, so this solution uses -0 instead.

Get ls to output one file per line, then translate newlines into nulls and tell xargs to use nulls as the delimiter:

ls -1 *mp3 | tr "\n" "\0" | xargs -0 mplayer

Old question, but another "pure razor" answer would be:

@Html.CheckBoxFor(model => model.As, htmlAttributes: new { @checked = true} )

If your server have a http service you can compress your directory and download the compressed file.

Compress:

tar -zcvf archive-name.tar.gz -C directory-name .

Download throught your browser:

http://the-server-ip/archive-name.tar.gz

If you don't have direct access to the server ip, do a ssh tunnel throught putty, and forward the 80 port in some local port, and you can download the file.

The problem must be with the parameters you are passing(You must be passing blank parameters). For example : http://www.myurl.com?id=5&name= Check if you are handling this at the server you are calling.

Instead of using subclassing/mixins, I like to use a generic class decorator

def comparable(cls):
    """ Class decorator providing generic comparison functionality """

    def __eq__(self, other):
        return isinstance(other, self.__class__) and self.__dict__ == other.__dict__

    def __ne__(self, other):
        return not self.__eq__(other)

    cls.__eq__ = __eq__
    cls.__ne__ = __ne__
    return cls

Usage:

@comparable
class Number(object):
    def __init__(self, x):
        self.x = x

a = Number(1)
b = Number(1)
assert a == b

Alternatively

with Pool() as pool: 
    pool.map(fits.open, [name + '.fits' for name in datainput])

The main new feature of Vim 8.1 is support for running a terminal in a Vim window.

:term will open the terminal in another window inside Vim.

Since char is a primitive type, you can just write c == ' '.
You only need to call equals() for reference types like String or Character.

Try adding a pair of class attributes, say 'even' and 'odd', to alternating list elements, e.g.

<ul>
    <li class="even"><a href="link">Link 1</a></li>
    <li class="odd"><a href="link">Link 2</a></li>
    <li class="even"><a href="link">Link 3</a></li>
    <li class="odd"><a href="link">Link 4</a></li>
    <li class="even"><a href="link">Link 5</a></li>
</ul>

In a <style> section of the HTML page, or in a linked stylesheet, you would define those same classes, specifying your desired background colours:

li.even { background-color: red; }
li.odd { background-color: blue; }

You might want to use a template library as your needs evolve to provide you with greater flexibility and to cut down on the typing. Why type all those list elements by hand?

Google has recently made public its internal Collaboratory project (link here). You can start a notebook in the same way as starting a Google Sheet or Google Doc, and then simply share the notebook or add collaborators..

For now, this is the easiest way for me.

As of swift 3.0 .normal state has been removed.you can use following to apply normal state.

myButton.setTitle("myTitle", for: [])

you can just do

select rownum, l.* from student  l where name like %ram%

this assigns the row number as the rows are fetched (so no guaranteed ordering of course).

if you wanted to order first do:

select rownum, l.*
  from (select * from student l where name like %ram% order by...) l;

if you want see select query output in pl/sql you need to use a explicit cursor. Which will hold active data set and by fetching each row at a time it will show all the record from active data set as long as it fetches record from data set by iterating in loop. This data will not be generated in tabular format this result will be in plain text format. Hope this will be helpful. For any other query you may ask....

set serveroutput on;
declare
cursor c1 is
   select foo, bar from foobar;
begin
  for i in c1 loop
    dbms_output.put_line(i.foo || ' ' || i.bar);
  end loop;
end;

We're talking about C++ right? Why on earth are we still using macros!?

C++ inline functions give you the same speed as a macro, with the added benefit of type-safety and parameter evaluation (which avoids the issue that Rodney and dwj mentioned.

inline const char * const BoolToString(bool b)
{
  return b ? "true" : "false";
}

Aside from that I have a few other gripes, particularly with the accepted answer :)

// this is used in C, not C++. if you want to use printf, instead include <cstdio>
//#include <stdio.h>
// instead you should use the iostream libs
#include <iostream>

// not only is this a C include, it's totally unnecessary!
//#include <stdarg.h>

// Macros - not type-safe, has side-effects. Use inline functions instead
//#define BOOL_STR(b) (b?"true":"false")
inline const char * const BoolToString(bool b)
{
  return b ? "true" : "false";
}

int main (int argc, char const *argv[]) {
    bool alpha = true;

    // printf? that's C, not C++
    //printf( BOOL_STR(alpha) );
    // use the iostream functionality
    std::cout << BoolToString(alpha);
    return 0;
}

Cheers :)

@DrPizza: Include a whole boost lib for the sake of a function this simple? You've got to be kidding?

I use this to avoid negative interval.

var seconds = (date1< date2)? (date2- date1).TotalSeconds: (date1 - date2).TotalSeconds;

[self.tableView setTableFooterView:footerView];

For SQL Sever:

Decimal Type is 128 bit signed number Float is a 64 bit signed number.

The real answer is Float, I was incorrect about decimal.

The reason is if you use a decimal you will never fill 64 bit of the decimal type.

Although decimal won't give you an error if you try to use a int type.

Here is a nice reference chart of the types.

In addition to @Daniel Li's answer, the nginx installation with Valet would use the Velet configuration as well, this is found in "/usr/local/etc/nginx/valet/valet.conf". The nginx.conf file would have imported this Valet conf file. The settings you need may be in the Valet file.

Use this extension, it generates xpaths based on id or class, which is probably what you want to use.

Click on the browser icon, the panel is shown on the right corner of the page, then click start inspect, then click on any element to get your xpath.

data: {"csrfmiddlewaretoken" : "{{csrf_token}}"}

You see "403 (FORBIDDEN)", because you don`t send "csrfmiddlewaretoken" parameter. In template each form has this: {% csrf_token %}. You should add "csrfmiddlewaretoken" to your ajax data dictionary. My example is sending "product_code" and "csrfmiddlewaretoken" to app "basket" view "remove":

$(function(){
    $('.card-body').on('click',function(){
        $.ajax({
          type: "post",
          url: "{% url 'basket:remove'%}",
          data: {"product_code": "07316", "csrfmiddlewaretoken" : "{{csrf_token}}" }
        });
    })
});

The differences between Model() and Model.objects.create() are the following:

1. INSERT vs UPDATE

   Model.save() does either INSERT or UPDATE of an object in a DB, while Model.objects.create() does only INSERT.

   Model.save() does

   • UPDATE If the object’s primary key attribute is set to a value that evaluates to True

   • INSERT If the object’s primary key attribute is not set or if the UPDATE didn’t update anything (e.g. if primary key is set to a value that doesn’t exist in the database).

2. Existing primary key

   If primary key attribute is set to a value and such primary key already exists, then Model.save() performs UPDATE, but Model.objects.create() raises IntegrityError.

   Consider the following models.py:

   class Subject(models.Model):
      subject_id = models.PositiveIntegerField(primary_key=True, db_column='subject_id')
      name = models.CharField(max_length=255)
      max_marks = models.PositiveIntegerField()
   

   1. Insert/Update to db with Model.save()

      physics = Subject(subject_id=1, name='Physics', max_marks=100)
      physics.save()
      math = Subject(subject_id=1, name='Math', max_marks=50)  # Case of update
      math.save()
      

      Result:

      Subject.objects.all().values()
      <QuerySet [{'subject_id': 1, 'name': 'Math', 'max_marks': 50}]>
      

   2. Insert to db with Model.objects.create()

      Subject.objects.create(subject_id=1, name='Chemistry', max_marks=100)
      IntegrityError: UNIQUE constraint failed: m****t.subject_id
      

   Explanation: In the example, math.save() does an UPDATE (changes name from Physics to Math, and max_marks from 100 to 50), because subject_id is a primary key and subject_id=1 already exists in the DB. But Subject.objects.create() raises IntegrityError, because, again the primary key subject_id with the value 1 already exists.

3. Forced insert

   Model.save() can be made to behave as Model.objects.create() by using force_insert=True parameter: Model.save(force_insert=True).

4. Return value

   Model.save() return None where Model.objects.create() return model instance i.e. package_name.models.Model

Conclusion: Model.objects.create() does model initialization and performs save() with force_insert=True.

Excerpt from the source code of Model.objects.create()

def create(self, **kwargs):
    """
    Create a new object with the given kwargs, saving it to the database
    and returning the created object.
    """
    obj = self.model(**kwargs)
    self._for_write = True
    obj.save(force_insert=True, using=self.db)
    return obj

Since, you are able to run Python in PowerShell. You can just do python <scriptName>.py to run the script. So, for a script named test.py containing

name = raw_input("Enter your name: ")
print "Hello, " + name

The PowerShell session would be

PS C:\Python27> python test.py
Enter your name: Monty Python
Hello, Monty Python

[Edit]

If you are doing this to trim the beginning of a log file, you can avoid loading the entire file by doing something like this:

// count the number of lines in the file
int count = 0;
using (var sr = new StreamReader("file.txt"))
{
    while (sr.ReadLine() != null) 
        count++;
}

// skip first (LOG_MAX - count) lines
count = LOG_MAX - count;
using (var sr = new StreamReader("file.txt"))
using (var sw = new StreamWriter("output.txt"))
{
    // skip several lines
    while (count > 0 && sr.ReadLine() != null) 
        count--;

    // continue copying
    string line = "";
    while ((line = sr.ReadLine()) != null)
        sw.WriteLine(line);
}

First of all, since File.ReadAllLines loads the entire file into a string array (string[]), copying to a list is redundant.

Second, you must understand that a List is implemented using a dynamic array under the hood. This means that CLR will need to allocate and copy several arrays until it can accommodate the entire file. Since the file is already on disk, you might consider trading speed for memory and working on disk data directly, or processing it in smaller chunks.

1. If you need to load it entirely in memory, at least try to leave in an array:

    string[] lines = File.ReadAllLines("file.txt");
   

2. If it really needs to be a List, load lines one by one:

    List<string> lines = new List<string>();
    using (var sr = new StreamReader("file.txt"))
    {
         while (sr.Peek() >= 0)
             lines.Add(sr.ReadLine());
    }
   

   Note: List<T> has a constructor which accepts a capacity parameter. If you know the number of lines in advance, you can prevent multiple allocations by preallocating the array in advance:

    List<string> lines = new List<string>(NUMBER_OF_LINES);
   

3. Even better, avoid storing the entire file in memory and process it "on the fly":

    using (var sr = new StreamReader("file.txt"))
    {
         string line;
         while ((line = sr.ReadLine()) != null) 
         {
             // process the file line by line
         }
    }
   

It should be noted that the documentation recommends using a Layout rather than Canvas.drawText directly. My full answer about using a StaticLayout is here, but I will provide a summary below.

String text = "This is some text.";

TextPaint textPaint = new TextPaint();
textPaint.setAntiAlias(true);
textPaint.setTextSize(16 * getResources().getDisplayMetrics().density);
textPaint.setColor(0xFF000000);

int width = (int) textPaint.measureText(text);
StaticLayout staticLayout = new StaticLayout(text, textPaint, (int) width, Layout.Alignment.ALIGN_NORMAL, 1.0f, 0, false);
staticLayout.draw(canvas);

Here is a fuller example in the context of a custom view:

public class MyView extends View {

    String mText = "This is some text.";
    TextPaint mTextPaint;
    StaticLayout mStaticLayout;

    // use this constructor if creating MyView programmatically
    public MyView(Context context) {
        super(context);
        initLabelView();
    }

    // this constructor is used when created from xml
    public MyView(Context context, AttributeSet attrs) {
        super(context, attrs);
        initLabelView();
    }

    private void initLabelView() {
        mTextPaint = new TextPaint();
        mTextPaint.setAntiAlias(true);
        mTextPaint.setTextSize(16 * getResources().getDisplayMetrics().density);
        mTextPaint.setColor(0xFF000000);

        // default to a single line of text
        int width = (int) mTextPaint.measureText(mText);
        mStaticLayout = new StaticLayout(mText, mTextPaint, (int) width, Layout.Alignment.ALIGN_NORMAL, 1.0f, 0, false);

        // New API alternate
        //
        // StaticLayout.Builder builder = StaticLayout.Builder.obtain(mText, 0, mText.length(), mTextPaint, width)
        //        .setAlignment(Layout.Alignment.ALIGN_NORMAL)
        //        .setLineSpacing(1, 0) // multiplier, add
        //        .setIncludePad(false);
        // mStaticLayout = builder.build();
    }

    @Override
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
        // Tell the parent layout how big this view would like to be
        // but still respect any requirements (measure specs) that are passed down.

        // determine the width
        int width;
        int widthMode = MeasureSpec.getMode(widthMeasureSpec);
        int widthRequirement = MeasureSpec.getSize(widthMeasureSpec);
        if (widthMode == MeasureSpec.EXACTLY) {
            width = widthRequirement;
        } else {
            width = mStaticLayout.getWidth() + getPaddingLeft() + getPaddingRight();
            if (widthMode == MeasureSpec.AT_MOST) {
                if (width > widthRequirement) {
                    width = widthRequirement;
                    // too long for a single line so relayout as multiline
                    mStaticLayout = new StaticLayout(mText, mTextPaint, width, Layout.Alignment.ALIGN_NORMAL, 1.0f, 0, false);
                }
            }
        }

        // determine the height
        int height;
        int heightMode = MeasureSpec.getMode(heightMeasureSpec);
        int heightRequirement = MeasureSpec.getSize(heightMeasureSpec);
        if (heightMode == MeasureSpec.EXACTLY) {
            height = heightRequirement;
        } else {
            height = mStaticLayout.getHeight() + getPaddingTop() + getPaddingBottom();
            if (heightMode == MeasureSpec.AT_MOST) {
                height = Math.min(height, heightRequirement);
            }
        }

        // Required call: set width and height
        setMeasuredDimension(width, height);
    }

    @Override
    protected void onDraw(Canvas canvas) {
        super.onDraw(canvas);
        // do as little as possible inside onDraw to improve performance

        // draw the text on the canvas after adjusting for padding
        canvas.save();
        canvas.translate(getPaddingLeft(), getPaddingTop());
        mStaticLayout.draw(canvas);
        canvas.restore();
    }
}

Starting in NumPy version 1.10, we have the method stack. It can stack arrays of any dimension (all equal):

# List of arrays.
L = [np.random.randn(5,4,2,5,1,2) for i in range(10)]

# Stack them using axis=0.
M = np.stack(L)
M.shape # == (10,5,4,2,5,1,2)
np.all(M == L) # == True

M = np.stack(L, axis=1)
M.shape # == (5,10,4,2,5,1,2)
np.all(M == L) # == False (Don't Panic)

# This are all true    
np.all(M[:,0,:] == L[0]) # == True
all(np.all(M[:,i,:] == L[i]) for i in range(10)) # == True

Enjoy,

Depending on how often you use this in your code you could consider the following:

macro

#define SIGN(x) ( (x) >= 0 )

Inline function

inline int sign(int x)
{
    return x >= 0;
}

Then you would just go:

bigInt.sign = sign(number); 

Use svn merge:

svn merge -c -[rev num that deleted the file] http://<path to repository>

So an example:

svn merge -c -12345 https://svn.mysite.com/svn/repo/project/trunk
             ^ The negative is important

For TortoiseSVN (I think...)

• Right click in Explorer, go to TortoiseSVN -> Merge...
• Make sure "Merge a range of revisions" is selected, click Next
• In the "Revision range to merge" textbox, specify the revision that removed the file
• Check the "Reverse merge" checkbox, click Next
• Click Merge

That is completely untested, however.

Edited by OP: This works on my version of TortoiseSVN (the old kind without the next button)

• Go to the folder that stuff was delated from
• Right click in Explorer, go to TortoiseSVN -> Merge...
• in the From section enter the revision that did the delete
• in the To section enter the revision before the delete.
• Click "merge"
• commit

The trick is to merge backwards. Kudos to sean.bright for pointing me in the right direction!

Edit: We are using different versions. The method I described worked perfectly with my version of TortoiseSVN.

Also of note is that if there were multiple changes in the commit you are reverse merging, you'll want to revert those other changes once the merge is done before you commit. If you don't, those extra changes will also be reversed.

If you're trying to convert a stream into text, you need to be aware of which encoding you want to use. You can then either pass an array of bytes into the String constructor and provide a Charset, or use InputStreamReader with the appropriate Charset instead.

Simply casting from int to char only works if you want ISO-8859-1, if you're reading bytes from a stream directly.

EDIT: If you are already using a Reader, then casting the return value of read() to char is the right way to go (after checking whether it's -1 or not)... but it's normally more efficient and convenient to call read(char[], int, int) to read a whole block of text at a time. Don't forget to check the return value though, to see how many characters have been read.

Unlike the C#/.NET class library (and most other sensible languages), when you pass a String in as the string-to-match argument to the string.replace method, it doesn't do a string replace. It converts the string to a RegExp and does a regex substitution. As Gumbo explains, a regex substitution requires the g?lobal flag, which is not on by default, to replace all matches in one go.

If you want a real string-based replace — for example because the match-string is dynamic and might contain characters that have a special meaning in regexen — the JavaScript idiom for that is:

var id= 'c_'+date.split('/').join('');

You need to add a parent with a relative position, inside this parent you can set the absolute position of your divs

<div> <------Relative
  <div/> <------Absolute
  <div/> <------Absolute
  <div/> <------Absolute
<div/>

Final result:

https://codepen.io/hiteshsahu/pen/XWKYEYb?editors=0100

<div class="container">
  <div class="header">TOP: I am at Top & above of body container</div>
  
    <div class="center">CENTER: I am at Top & in Center of body container</div>
  
  <div class="footer">BOTTOM: I am at Bottom & above of body container</div>
</div>
    

Set HTML Body full width

 html, body {
  overflow: hidden;
  width: 100%;
  height: 100%;
  margin: 0;
  padding: 0;
}

After that, you can set a div with the relative position to take full width and height

.container {
  position: relative;
  background-color: blue;
  height: 100%;
  width: 100%;
  border:1px solid;
  color: white;
  background-image: url("https://images.pexels.com/photos/5591663/pexels-photo-5591663.jpeg?auto=compress&cs=tinysrgb&dpr=2&h=750&w=1260");
  background-color: #cccccc;
}

Inside this div with the relative position you can put your div with absolute positions

On TOP above the container

.header {
  position: absolute;
  margin-top: -10px;
  background-color: #d81b60 ;
  left:0;
  right:0;
  margin:15px;
  padding:10px;
  font-size: large;
}

On BOTTOM above the container

.footer {
  position: absolute;
  background-color: #00bfa5;
  left:0;
  right:0;
  bottom:0;
  margin:15px;
  padding:10px;
  color: white;
  font-size: large;

}

In CENTER above the container

.center {
  position: absolute;
  background-color: #00bfa5;
  left:  30%;
  right: 30%;
  bottom:30%;
  top: 30%;
  margin:10px;
  padding:10px;
  color: white;
  font-size: large;
}

A solution that helped me: Go to Tools > NuGet Package Manager > Manage NuGet Packaged for Solution... > Browse > Search for System.IO.Compression.ZipFile and install it

As a quick solution you can copy the JavaFX runtime JAR file and those referenced from Oracle JRE(JDK) or any self-contained application that uses JavaFX(e.g. JavaFX Scene Builder 2.0):

cp <JRE_WITH_JAVAFX_HOME>/lib/ext/jfxrt.jar     <JRE_HOME>/lib/ext/
cp <JRE_WITH_JAVAFX_HOME>/lib/javafx.properties <JRE_HOME>/lib/
cp <JRE_WITH_JAVAFX_HOME>/lib/amd64/libprism_*  <JRE_HOME>/lib/amd64/
cp <JRE_WITH_JAVAFX_HOME>/lib/amd64/libglass.so <JRE_HOME>/lib/amd64/
cp <JRE_WITH_JAVAFX_HOME>/lib/amd64/libjavafx_* <JRE_HOME>/lib/amd64/

just make sure you have the gtk 2.18 or higher

You need to convert those to actual dates instead of strings, try this:

SELECT *
FROM <TABLENAME>
WHERE start_date BETWEEN TO_DATE('2010-01-15','YYYY-MM-DD') AND TO_DATE('2010-01-17', 'YYYY-MM-DD');

Edited to deal with format as specified:

SELECT *
FROM <TABLENAME>
WHERE start_date BETWEEN TO_DATE('15-JAN-10','DD-MON-YY') AND TO_DATE('17-JAN-10','DD-MON-YY');

if( (new Date(first).getTime() > new Date(second).getTime()))
{
    ----------------------------------
}

If you are not so keen on having to decorate code with Attributes as I am, esp when you cant tell at compile time what will happen here is my solution.

Using the Javascript Serializer

    public static class JsonSerializerExtensions
    {
        public static string ToJsonString(this object target,bool ignoreNulls = true)
        {
            var javaScriptSerializer = new JavaScriptSerializer();
            if(ignoreNulls)
            {
                javaScriptSerializer.RegisterConverters(new[] { new PropertyExclusionConverter(target.GetType(), true) });
            }
            return javaScriptSerializer.Serialize(target);
        }

        public static string ToJsonString(this object target, Dictionary<Type, List<string>> ignore, bool ignoreNulls = true)
        {
            var javaScriptSerializer = new JavaScriptSerializer();
            foreach (var key in ignore.Keys)
            {
                javaScriptSerializer.RegisterConverters(new[] { new PropertyExclusionConverter(key, ignore[key], ignoreNulls) });
            }
            return javaScriptSerializer.Serialize(target);
        }
    }


public class PropertyExclusionConverter : JavaScriptConverter
    {
        private readonly List<string> propertiesToIgnore;
        private readonly Type type;
        private readonly bool ignoreNulls;

        public PropertyExclusionConverter(Type type, List<string> propertiesToIgnore, bool ignoreNulls)
        {
            this.ignoreNulls = ignoreNulls;
            this.type = type;
            this.propertiesToIgnore = propertiesToIgnore ?? new List<string>();
        }

        public PropertyExclusionConverter(Type type, bool ignoreNulls)
            : this(type, null, ignoreNulls){}

        public override IEnumerable<Type> SupportedTypes
        {
            get { return new ReadOnlyCollection<Type>(new List<Type>(new[] { this.type })); }
        }

        public override IDictionary<string, object> Serialize(object obj, JavaScriptSerializer serializer)
        {
            var result = new Dictionary<string, object>();
            if (obj == null)
            {
                return result;
            }
            var properties = obj.GetType().GetProperties();
            foreach (var propertyInfo in properties)
            {
                if (!this.propertiesToIgnore.Contains(propertyInfo.Name))
                {
                    if(this.ignoreNulls && propertyInfo.GetValue(obj, null) == null)
                    {
                         continue;
                    }
                    result.Add(propertyInfo.Name, propertyInfo.GetValue(obj, null));
                }
            }
            return result;
        }

        public override object Deserialize(IDictionary<string, object> dictionary, Type type, JavaScriptSerializer serializer)
        {
            throw new NotImplementedException(); //Converter is currently only used for ignoring properties on serialization
        }
    }

Use break.

Unrelated to your question, I see in your code the line:

Violated = !(name.firstname == null) ? false : true;

In this line, you take a boolean value (name.firstname == null). Then, you apply the ! operator to it. Then, if the value is true, you set Violated to false; otherwise to true. So basically, Violated is set to the same value as the original expression (name.firstname == null). Why not use that, as in:

Violated = (name.firstname == null);

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

Create a vectorized method

def calc_xb_minus_xa(df):
    time_dict = {
        '<Minute>': 'm',
        '<Hour>': 'h',
        '<Day>': 'D',
        '<Week>': 'W',
        '<Month>': 'M',
        '<Year>': 'Y'
    }

    time_delta = df.at[df.index[0], 'end_time'] - df.at[df.index[0], 'open_time']
    offset_base_name = str(to_offset(time_delta).base)
    time_term = time_dict.get(offset_base_name)

    result = (df.end_time - df.open_time) / np.timedelta64(1, time_term)
    return result

Then in your df do:

df['x'] = calc_xb_minus_xa(df)

This will work for minutes, hours, days, weeks, month and Year. open_time and end_time need to change according your df

Way around would be moving M2 from user variables to system variables

Create a "module" object and declare variables in there. Unlike class-objects that have to be instantiated each time, the module objects are always available. Therefore, a public variable, function, or property in a "module" will be available to all the other objects in the VBA project, macro, Excel formula, or even within a MS Access JET-SQL query def.

Command:

grep -rl --include="*.js" "searchString" ${PWD}

Returned output:

/root/test/bas.js

"\n\r" produces 2 new lines while "\n","\r" & "\r\n" produce single lines if, in the Header, you use content-type: text/plain.

Beware: If you do the Following php code:

    $message='ab<br>cd<br>e<br>f';
print $message.'<br><br>';
    $message=str_replace('<br>',"\r\n",$message);
print $message;

you get the following in the Windows browser:

ab
cd
e
f

ab cd e f

and with content-type: text/plain you get the following in an email output;

ab
cd
e
f

Here is a very simple and effective solution using the split and mtime functions:

$date="30/07/2010 13:24"; //Date example
list($day, $month, $year, $hour, $minute) = split('[/ :]', $date); 

//The variables should be arranged according to your date format and so the separators
$timestamp = mktime($hour, $minute, 0, $month, $day, $year);
echo date("r", $timestamp);

It worked like a charm for me.

This should be tested in mysql, not postgresql:

SELECT table_schema, # "DB Name", 
Round(Sum(data_length + index_length) / 1024 / 1024, 1) # "DB Size in MB" 
FROM   information_schema.tables 
GROUP  BY table_schema; 

This boils down to two distinct steps:

1. Figure out when your condition is true, and hence compute a vector of booleans, or, as I prefer, their indices by wrapping it into which()
2. Create an updated data.frame by excluding the indices from the previous step.

Here is an example:

R> set.seed(42)
R> DF <- data.frame(sub=rep(1:4, each=4), day=sample(1:4, 16, replace=TRUE))
R> DF
   sub day
1    1   4
2    1   4
3    1   2
4    1   4
5    2   3
6    2   3
7    2   3
8    2   1
9    3   3
10   3   3
11   3   2
12   3   3
13   4   4
14   4   2
15   4   2
16   4   4
R> ind <- which(with( DF, sub==2 & day==3 ))
R> ind
[1] 5 6 7
R> DF <- DF[ -ind, ]
R> table(DF)
   day
sub 1 2 3 4
  1 0 1 0 3
  2 1 0 0 0
  3 0 1 3 0
  4 0 2 0 2
R> 

And we see that sub==2 has only one entry remaining with day==1.

Edit The compound condition can be done with an 'or' as follows:

ind <- which(with( DF, (sub==1 & day==2) | (sub=3 & day=4) ))

and here is a new full example

R> set.seed(1)
R> DF <- data.frame(sub=rep(1:4, each=5), day=sample(1:4, 20, replace=TRUE))
R> table(DF)
   day
sub 1 2 3 4
  1 1 2 1 1
  2 1 0 2 2
  3 2 1 1 1
  4 0 2 1 2
R> ind <- which(with( DF, (sub==1 & day==2) | (sub==3 & day==4) ))
R> ind
[1]  1  2 15
R> DF <- DF[-ind, ]
R> table(DF)
   day
sub 1 2 3 4
  1 1 0 1 1
  2 1 0 2 2
  3 2 1 1 0
  4 0 2 1 2
R> 

A small change of cgnorthcutt's solution, considering the string type variables

def get_confusion_matrix(l1, l2):

    assert len(l1)==len(l2), "Two lists have different size."

    K = len(np.unique(l1))

    # create label-index value
    label_index = dict(zip(np.unique(l1), np.arange(K)))

    result = np.zeros((K, K))
    for i in range(len(l1)):
        result[label_index[l1[i]]][label_index[l2[i]]] += 1

    return result

The layout to use is indeed "2006-01-02T15:04:05.000Z" described in RickyA's answer.
It isn't "the time of the first commit of go", but rather a mnemonic way to remember said layout.
See pkg/time:

The reference time used in the layouts is:

Mon Jan 2 15:04:05 MST 2006

which is Unix time 1136239445.
Since MST is GMT-0700, the reference time can be thought of as

 01/02 03:04:05PM '06 -0700

(1,2,3,4,5,6,7, provided you remember that 1 is for the month, and 2 for the day, which is not easy for an European like myself, used to the day-month date format)

As illustrated in "time.parse : why does golang parses the time incorrectly?", that layout (using 1,2,3,4,5,6,7) must be respected exactly.

parent.location.reload();

This should work.

Ok, after all the possibilities I have chosen to work with "Java Monitoring and Management"
Overview is here
That allows you to control one application from another one in relatively easy way. You can call the controlling application from a script to stop controlled application gracefully before killing it.

Here is the simplified code:

Controlled application:
run it with the folowing VM parameters:
-Dcom.sun.management.jmxremote
-Dcom.sun.management.jmxremote.port=9999
-Dcom.sun.management.jmxremote.authenticate=false
-Dcom.sun.management.jmxremote.ssl=false

//ThreadMonitorMBean.java
public interface ThreadMonitorMBean
{
String getName();
void start();
void stop();
boolean isRunning();
}

// ThreadMonitor.java
public class ThreadMonitor implements ThreadMonitorMBean
{
private Thread m_thrd = null;

public ThreadMonitor(Thread thrd)
{
    m_thrd = thrd;
}

@Override
public String getName()
{
    return "JMX Controlled App";
}

@Override
public void start()
{
    // TODO: start application here
    System.out.println("remote start called");
}

@Override
public void stop()
{
    // TODO: stop application here
    System.out.println("remote stop called");

    m_thrd.interrupt();
}

public boolean isRunning()
{
    return Thread.currentThread().isAlive();
}

public static void main(String[] args)
{
    try
    {
        System.out.println("JMX started");

        ThreadMonitorMBean monitor = new ThreadMonitor(Thread.currentThread());

        MBeanServer server = ManagementFactory.getPlatformMBeanServer();

        ObjectName name = new ObjectName("com.example:type=ThreadMonitor");

        server.registerMBean(monitor, name);

        while(!Thread.interrupted())
        {
            // loop until interrupted
            System.out.println(".");
            try 
            {
                Thread.sleep(1000);
            } 
            catch(InterruptedException ex) 
            {
                Thread.currentThread().interrupt();
            }
        }
    }
    catch(Exception e)
    {
        e.printStackTrace();
    }
    finally
    {
        // TODO: some final clean up could be here also
        System.out.println("JMX stopped");
    }
}
}

Controlling application:
run it with the stop or start as the command line argument

public class ThreadMonitorConsole
{

public static void main(String[] args)
{
    try
    {   
        // connecting to JMX
        System.out.println("Connect to JMX service.");
        JMXServiceURL url = new JMXServiceURL("service:jmx:rmi:///jndi/rmi://:9999/jmxrmi");
        JMXConnector jmxc = JMXConnectorFactory.connect(url, null);
        MBeanServerConnection mbsc = jmxc.getMBeanServerConnection();

        // Construct proxy for the the MBean object
        ObjectName mbeanName = new ObjectName("com.example:type=ThreadMonitor");
        ThreadMonitorMBean mbeanProxy = JMX.newMBeanProxy(mbsc, mbeanName, ThreadMonitorMBean.class, true);

        System.out.println("Connected to: "+mbeanProxy.getName()+", the app is "+(mbeanProxy.isRunning() ? "" : "not ")+"running");

        // parse command line arguments
        if(args[0].equalsIgnoreCase("start"))
        {
            System.out.println("Invoke \"start\" method");
            mbeanProxy.start();
        }
        else if(args[0].equalsIgnoreCase("stop"))
        {
            System.out.println("Invoke \"stop\" method");
            mbeanProxy.stop();
        }

        // clean up and exit
        jmxc.close();
        System.out.println("Done.");    
    }
    catch(Exception e)
    {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
}
}

That's it. :-)

Define the range between the numbers:

r = range(1,10)

Then use it:

if num in r:
    print("All right!")

You would do:

char c = str[1];

Or even:

char c = "Hello"[1];

edit: updated to find the "E".

It wasn't working for me. I run crontab with sudo, so I switched to root, did the above suggestions, and crontab would open in vim, but it still wouldn't from my user account. Finally I ran sudo select-editor from the user account and that did the trick.

You could try using the <col> tag manage table styling for all rows but you will need to set the table-layout:fixed style on the <table> or the tables css class and set the overflow style for the cells

http://www.w3schools.com/TAGS/tag_col.asp

<table class="fixed">
    <col width="20px" />
    <col width="30px" />
    <col width="40px" />
    <tr>
        <td>text</td>
        <td>text</td>
        <td>text</td>
    </tr>
</table>

and this be your CSS

table.fixed { table-layout:fixed; }
table.fixed td { overflow: hidden; }

This is the shortest version I could find,saving/hiding an extra conversion:

pil_image = PIL.Image.open('image.jpg')
opencvImage = cv2.cvtColor(numpy.array(pil_image), cv2.COLOR_RGB2BGR)

If reading a file from a URL:

import cStringIO
import urllib
file = cStringIO.StringIO(urllib.urlopen(r'http://stackoverflow.com/a_nice_image.jpg').read())
pil_image = PIL.Image.open(file)
opencvImage = cv2.cvtColor(numpy.array(pil_image), cv2.COLOR_RGB2BGR)

• Edit ---> Project Settings ---> Time ... decrease "Fixed Timestep" value .. This will solve the problem but it can affect performance negatively.

• Another solution is could be calculate the coordinates (for example, you have a ball and wall. Ball will hit to wall. So calculate coordinates of wall and set hitting process according these cordinates )

It is possible, if you're using a browser which supports the CSS :valid pseudo-class and the pattern validation attribute on inputs -- which includes most modern browsers except IE9.

For instance, to change the text of an input from black to green when the correct answer is entered:

input {_x000D_
  color: black;_x000D_
}_x000D_
input:valid {_x000D_
  color: green;_x000D_
}

<p>Which country has fifty states?</p>_x000D_
_x000D_
<input type="text" pattern="^United States$">

Provided that the remote repository is origin, and that you're interested in master:

git fetch origin
git reset --hard origin/master

This tells it to fetch the commits from the remote repository, and position your working copy to the tip of its master branch.

All your local commits not common to the remote will be gone.

This was the best solution I found after more time than I care to admit. Basically, add target="_self" to each link that you need to insure a page reload.

Here is email code I used in one of my databases. I just made variables for the person I wanted to send it to, CC, subject, and the body. Then you just use the DoCmd.SendObject command. I also set it to "True" after the body so you can edit the message before it automatically sends.

Public Function SendEmail2()

Dim varName As Variant          
Dim varCC As Variant            
Dim varSubject As Variant      
Dim varBody As Variant          

varName = "[email protected]"
varCC = "[email protected], [email protected]"
'separate each email by a ','

varSubject = "Hello"
'Email subject

varBody = "Let's get ice cream this week"

'Body of the email
DoCmd.SendObject , , , varName, varCC, , varSubject, varBody, True, False
'Send email command. The True after "varBody" allows user to edit email before sending.
'The False at the end will not send it as a Template File

What is wrong with Date.parse method?

str = "Tue, 10 Aug 2010 01:20:19 -0400 (EDT)"
date = Date.parse str
=> #<Date: 4910837/2,0,2299161>
puts date
2010-08-10

It seems to work.

The only problem here is time zone. If you want date in UTC time zone, then it is better to use Time object, suppose we have string:

str = "Tue, 10 Aug 2010 01:20:19 +0400"
puts Date.parse str
2010-08-10
puts Date.parse(Time.parse(str).utc.to_s)
2010-08-09

I couldn't find simpler method to convert Time to Date.

In case you are looking for parsing (positive, unsigned) integers instead of floats, you can use the isdigit() function for string objects.

>>> a = "03523"
>>> a.isdigit()
True
>>> b = "963spam"
>>> b.isdigit()
False

String Methods - isdigit(): Python2, Python3

There's also something on Unicode strings, which I'm not too familiar with Unicode - Is decimal/decimal

worth adding a lower in there so you don't find yourself wondering why the JPG's aren't showing up in your list.

os.path.splitext(filename)[1][1:].strip().lower()

From the JavaDocs of the ArrayList

The iterators returned by this class's iterator and listIterator methods are fail-fast: if the list is structurally modified at any time after the iterator is created, in any way except through the iterator's own remove or add methods, the iterator will throw a ConcurrentModificationException.

This solution works for me

var DELAY = 250, clicks = 0, timer = null;

$(".fc-event").click(function(e) {
    if (timer == null) {
        timer = setTimeout(function() {
           clicks = 0;
            timer = null;
            // single click code
        }, DELAY);
    }

    if(clicks === 1) {
         clearTimeout(timer);
         timer = null;
         clicks = -1;
         // double click code
    }
    clicks++;
});

If you want to use a character as a small integer, the safest way to do it is with the int8_tand uint8_t types.

It works fine. I tested it like this:

String command = @"C:\Doit.bat";

ProcessInfo = new ProcessStartInfo("cmd.exe", "/c " + command);
// ProcessInfo.CreateNoWindow = true;

I commented out turning off the window so I could SEE it run.

Because constructors are an implementation detail - they're not something that a user of an interface/superclass can actually invoke at all. By the time they get an instance, it's already been constructed; and vice-versa, at the time you construct an object there's by definition no variable it's currently assigned to.

Think about what it would mean to force all subclasses to have an inherited constructor. I argue it's clearer to pass the variables in directly than for the class to "magically" have a constructor with a certain number of arguments just because it's parent does.

There is also an .isInstance method on the "Class" class. if you get an object's class via myBanana.getClass() you can see if your object myApple is an instance of the same class as myBanana via

myBanana.getClass().isInstance(myApple)

There may be situations when df.reset_index() cannot be used (e.g., when you need the index, too). In this case, use index.get_level_values() to access index values directly:

df['Trial'] = df.index.get_level_values(0)
df['measurement'] = df.index.get_level_values(1)

This will assign index values to individual columns and keep the index.

See the docs for further info.

File outputfile = new File("image.jpg");
ImageIO.write(bufferedImage, "jpg", outputfile);

If you find yourself applying those 2 roles often you can wrap them in their own Authorize. This is really an extension of the accepted answer.

using System.Web.Mvc;

public class AuthorizeAdminOrMember : AuthorizeAttribute
{
    public AuthorizeAdminOrMember()
    {
        Roles = "members, admin";
    }
}

And then apply your new authorize to the Action. I think this looks cleaner and reads easily.

public class MyController : Controller
{
    [AuthorizeAdminOrMember]
    public ActionResult MyAction()
    {
        return null;
    }
}

Try this:

 window.location.href = "http://www.gorissen.info/Pierre/maps/googleMapLocation.php?lat="+elemA+"&lon="+elemB+"&setLatLon=Set";

To put a variable in a string enclose the variable in quotes and addition signs like this:

var myname = "BOB";
var mystring = "Hi there "+myname+"!"; 

Just remember that one rule!

Going off of tbradley22's answer, but using .map instead:

var a = ["car", "bike", "scooter"];
a.map(function(entry) {
    var singleObj = {};
    singleObj['type'] = 'vehicle';
    singleObj['value'] = entry;
    return singleObj;
});

Building a little more on Anton's answer, you can add all the columns like this:

df['sum'] = df[list(df.columns)].sum(axis=1)

Batch files can be run on Linux. This article explains how (http://www.linux.org/threads/running-windows-batch-files-on-linux.7610/).

Swift 2.0

extension Dictionary {

    mutating func unionInPlace(dictionary: Dictionary) {
        dictionary.forEach { self.updateValue($1, forKey: $0) }
    }

    func union(var dictionary: Dictionary) -> Dictionary {
        dictionary.unionInPlace(self)
        return dictionary
    }
}

I think you can't do that but atleast you can update it. In order to edit an existing row in a DataTable, you need to locate the DataRow you want to edit, and then assign the updated values to the desired columns.

Example,

DataSet1.Tables(0).Rows(4).Item(0) = "Updated Company Name"
DataSet1.Tables(0).Rows(4).Item(1) = "Seattle"

The best source is probably Apple's official documentation. The specific variable you are looking for is CONFIGURATION.

I use Apache Derby for pretty much all of my embedded database needs. You can also use Sun's Java DB that is based on Derby but the latest version of Derby is much newer. It supports a lot of options that commercial, native databases support but is much smaller and easier to embed. I've had some database tables with more than a million records with no issues.

I used to use HSQLDB and Hypersonic about 3 years ago. It has some major performance issues at the time and I switch to Derby from it because of those issues. Derby has been solid even when it was in incubator at Apache.

You may use:

if ( frm.product.value=="F" ){
    var $select_box = $('[name=val]');
    $select_box.find('[value=A],[value=C]').remove(); 
}

Update: If you modify your select box a bit to this

<select name="val" size="1" >
  <option id="A" value="A">Apple</option>
  <option id="C" value="C">Cars</option>
  <option id="H" value="H">Honda</option>
  <option id="F" value="F">Fiat</option>
  <option id="I" value="I">Indigo</option>                    
</select> 

the non-jQuery solution would be this

if ( frm.product.value=="F" ){
    var elem = document.getElementById('A');
    elem.parentNode.removeChild(elem);
    var elem = document.getElementById('C');
    elem.parentNode.removeChild(elem);
}

Another simple way:

ActiveSheet.Rows(ActiveSheet.UsedRange.Rows.Count+1).Select    
Selection.EntireRow.Delete

or simpler:

ActiveSheet.Rows(ActiveSheet.UsedRange.Rows.Count+1).EntireRow.Delete

The Basics

Look at these to build a solution more or less from scratch:

• Start from the basics: The Java Tutorial's chapter on Networking, including Working With URLs
• Make things easier for yourself: Apache HttpComponents (including HttpClient)

The Easily Glued-Up and Stitched-Up Stuff

You always have the option of calling external tools from Java using the exec() and similar methods. For instance, you could use wget, or cURL.

The Hardcore Stuff

Then if you want to go into more fully-fledged stuff, thankfully the need for automated web-testing as given us very practical tools for this. Look at:

• HtmlUnit (powerful and simple)
• Selenium, Selenium-RC
• WebDriver/Selenium2 (still in the works)
• JBehave with JBehave Web

Some other libs are purposefully written with web-scraping in mind:

• JSoup
• Jaunt

Some Workarounds

Java is a language, but also a platform, with many other languages running on it. Some of which integrate great syntactic sugar or libraries to easily build scrapers.

Check out:

• Groovy (and its XmlSlurper)
• or Scala (with great XML support as presented here and here)

If you know of a great library for Ruby (JRuby, with an article on scraping with JRuby and HtmlUnit) or Python (Jython) or you prefer these languages, then give their JVM ports a chance.

Some Supplements

Some other similar questions:

• Scrape data from HTML using Java
• Options for HTML Scraping

I found this function on a blog

 ggplotRegression <- function (fit) {

    `require(ggplot2)

    ggplot(fit$model, aes_string(x = names(fit$model)[2], y = names(fit$model)[1])) + 
      geom_point() +
      stat_smooth(method = "lm", col = "red") +
      labs(title = paste("Adj R2 = ",signif(summary(fit)$adj.r.squared, 5),
                         "Intercept =",signif(fit$coef[[1]],5 ),
                         " Slope =",signif(fit$coef[[2]], 5),
                         " P =",signif(summary(fit)$coef[2,4], 5)))
    }`

once you loaded the function you could simply

ggplotRegression(fit)

you can also go for ggplotregression( y ~ x + z + Q, data)

Hope this helps.

To change indicator color and height programmatically you can use reflection. for example for indicator color use code below:

        try {
            Field field = TabLayout.class.getDeclaredField("mTabStrip");
            field.setAccessible(true);
            Object ob = field.get(tabLayout);
            Class<?> c = Class.forName("android.support.design.widget.TabLayout$SlidingTabStrip");
            Method method = c.getDeclaredMethod("setSelectedIndicatorColor", int.class);
            method.setAccessible(true);
            method.invoke(ob, Color.RED);//now its ok
        } catch (NoSuchFieldException e) {
            e.printStackTrace();
        } catch (NoSuchMethodException e) {
            e.printStackTrace();
        } catch (InvocationTargetException e) {
            e.printStackTrace();
        } catch (IllegalAccessException e) {
            e.printStackTrace();
        } catch (ClassNotFoundException e) {
            e.printStackTrace();
        }

and to change indicator height use "setSelectedIndicatorHeight" instead of "setSelectedIndicatorColor" then invoke it by your desired height

I know this is a late answer but you could manually change the 7 font declarations in the latest version of Bootstrap:

html {
  font-family: sans-serif;
}

body {
  font-family: sans-serif;
}

pre, code, kbd, samp {
  font-family: monospace;
}

input, button, select, optgroup, textarea {
  font-family: inherit;
}

.tooltip {
  font-family: sans-serif;
}

.popover {
  font-family: sans-serif;
}

.text-monospace {
  font-family: monospace;
}

Good luck.

I've solved the problem , and I will explain how :

1. Download Github For Windows client and install it.
2. After The client successfully installed , connect it with your github account.It should be easy , just follow the wizard.
3. Then you should add git.exe location to your "Path Variable". The location you should add will probably be something like : C:\Users\Your_Username\AppData\Local\GitHub\PortableGit_ca477551eeb4aea0e4ae9fcd3358bd96720bb5c8\bin

Alternatively , if you don't want to add to environment variables. You can open the android studio and go to : Settings -> Version Control -> Git In text box next to "Path to Git Executable" you will see "git.exe" , just give it a full path like so : C:\Users\Your_Username\AppData\Local\GitHub\PortableGit_ca477551eeb4aea0e4ae9fcd3358bd96720bb5c8\bin\git.exe

Hope it saved your time . Happy coding :)

EDIT : For latest Github for windows versions some can find the git.exe under "...\cmd\git.exe" rather than "...\bin\git.exe".

In the head section of your html place your custom.css below bootstrap.css.

<link href="bootstrap.min.css" rel="stylesheet">
<link href="custom.css" rel="stylesheet">

Then in custom.css you have to use the exact same selector for the element you want to override. In the case of legend it just stays legend in your custom.css because bootstrap hasn't got any selectors more specific.

legend {
  display: inline;
  width: auto;
  padding: 0;
  margin: 0;
  font-size: medium;
  line-height: normal;
  color: #000000;
  border: 0;
  border-bottom: none;
}

But in case of h1 for example you have to take care of the more specific selectors like .jumbotron h1 because

h1 {
  line-height: 2;
  color: #f00;
}

will not override

.jumbotron h1,
.jumbotron .h1 {
  line-height: 1;
  color: inherit;
}

Here is a helpfull explantion of specificity of css selectors which you need to understand to know exactly which style rules will apply to an element. http://css-tricks.com/specifics-on-css-specificity/

Everything else is just a matter of copy/paste and edit styles.

You would do something like this by tapping into the scroll event handler on window, and using another table with a fixed position to show the header at the top of the page.

HTML:

<table id="header-fixed"></table>

CSS:

#header-fixed {
    position: fixed;
    top: 0px; display:none;
    background-color:white;
}

JavaScript:

var tableOffset = $("#table-1").offset().top;
var $header = $("#table-1 > thead").clone();
var $fixedHeader = $("#header-fixed").append($header);

$(window).bind("scroll", function() {
    var offset = $(this).scrollTop();

    if (offset >= tableOffset && $fixedHeader.is(":hidden")) {
        $fixedHeader.show();
    }
    else if (offset < tableOffset) {
        $fixedHeader.hide();
    }
});

This will show the table head when the user scrolls down far enough to hide the original table head. It will hide again when the user has scrolled the page up far enough again.

Working example: http://jsfiddle.net/andrewwhitaker/fj8wM/

Enumerations are used to represent a set of integer values.

The class keyword after the enum specifies that the enumeration is strongly typed and its enumerators are scoped. This way enum classes prevents accidental misuse of constants.

For Example:

enum class Animal{Dog, Cat, Tiger};
enum class Pets{Dog, Parrot};

Here we can not mix Animal and Pets values.

Animal a = Dog;       // Error: which DOG?    
Animal a = Pets::Dog  // Pets::Dog is not an Animal

JSON is similar to other data formats like XML - if you need to transmit more data, you just send more data. There's no inherent size limitation to the JSON request. Any limitation would be set by the server parsing the request. (For instance, ASP.NET has the "MaxJsonLength" property of the serializer.)

Is this what you're looking for?

if (request instanceof HttpServletRequest) {
 String url = ((HttpServletRequest)request).getRequestURL().toString();
 String queryString = ((HttpServletRequest)request).getQueryString();
}

To Reconstruct:

System.out.println(url + "?" + queryString);

Info on HttpServletRequest.getRequestURL() and HttpServletRequest.getQueryString().

@heridev and I created a small function in jQuery.

You can try next:

jQuery

// apply the two-digits behaviour to elements with 'two-digits' as their class
$( function() {
    $('.two-digits').keyup(function(){
        if($(this).val().indexOf('.')!=-1){         
            if($(this).val().split(".")[1].length > 2){                
                if( isNaN( parseFloat( this.value ) ) ) return;
                this.value = parseFloat(this.value).toFixed(2);
            }  
         }            
         return this; //for chaining
    });
});

In all RDBMS, the two ways of counting are equivalent in terms of what result they produce. Regarding performance, I have not observed any performance difference in SQL Server, but it may be worth pointing out that some RDBMS, e.g. PostgreSQL 11, have less optimal implementations for COUNT(1) as they check for the argument expression's nullability as can be seen in this post.

I've found a 10% performance difference for 1M rows when running:

-- Faster
SELECT COUNT(*) FROM t;

-- 10% slower
SELECT COUNT(1) FROM t;

split_part() does what you want in one step:

SELECT split_part(col, ',', 1) AS col1
     , split_part(col, ',', 2) AS col2
     , split_part(col, ',', 3) AS col3
     , split_part(col, ',', 4) AS col4
FROM   tbl;

Add as many lines as you have items in col (the possible maximum). Columns exceeding data items will be empty strings ('').

You can change the array type without converting like this:

a.dtype = numpy.float32

but first you have to change all the integers to something that will be interpreted as the corresponding float. A very slow way to do this would be to use python's struct module like this:

def toi(i):
    return struct.unpack('i',struct.pack('f',float(i)))[0]

...applied to each member of your array.

But perhaps a faster way would be to utilize numpy's ctypeslib tools (which I am unfamiliar with)

- edit -

Since ctypeslib doesnt seem to work, then I would proceed with the conversion with the typical numpy.astype method, but proceed in block sizes that are within your memory limits:

a[0:10000] = a[0:10000].astype('float32').view('int32')

...then change the dtype when done.

Here is a function that accomplishes the task for any compatible dtypes (only works for dtypes with same-sized items) and handles arbitrarily-shaped arrays with user-control over block size:

import numpy

def astype_inplace(a, dtype, blocksize=10000):
    oldtype = a.dtype
    newtype = numpy.dtype(dtype)
    assert oldtype.itemsize is newtype.itemsize
    for idx in xrange(0, a.size, blocksize):
        a.flat[idx:idx + blocksize] = \
            a.flat[idx:idx + blocksize].astype(newtype).view(oldtype)
    a.dtype = newtype

a = numpy.random.randint(100,size=100).reshape((10,10))
print a
astype_inplace(a, 'float32')
print a

The problem I had was because I had made a database in my LocalDb.
If that's the case then you have to write is as shown below:

    "SELECT * FROM <DatabaseName>.[dbo].[Projects]"

Replace with your database name.
You can probably also drop the "[ ]"

When I came out of college, the first real production-worthy C++ code I saw had these arcane #ifndef ... #endif directives in between them where the headers were defined. I asked the guy who was writing the code about these overarching things in a very naive fashion and was introduced to world of large-scale programming.

Coming back to the point, using directives to prevent duplicate header definitions was the first thing I learned when it came to reducing compiling times.
