After some fiddling with a script I came to this action. Copy and save it in a .bat file:

FOR /F "usebackq tokens=5" %%i IN (`netstat -aon ^| find "3306"`) DO taskkill /F /PID %%i

Change 'find "3306"' in the port number which needs to be free. Then run the file as administrator. It will kill all the processes running on this port.

Quite an old question, but might be helpful to somebody in need.

If you know the url, 1. open the chrome browser, 2. open developer tools in chrome , 3. Put the url in search bar and hit enter 4. look in network tab, you will see the ip and port both

If you want to use this in a more general context, you should make sure, that the socket that you open also gets closed. So the check should be more like this:

import socket
from contextlib import closing

def check_socket(host, port):
    with closing(socket.socket(socket.AF_INET, socket.SOCK_STREAM)) as sock:
        if sock.connect_ex((host, port)) == 0:
            print "Port is open"
        else:
            print "Port is not open"

Here's one that works for both Mac and Linux:

netstat -aln | awk '$6 == "LISTEN" && $4 ~ "[\\.\:]445$"'

Actually, you can just run the service using /mysqld --PORT 1234, it would force mysql to run on the specified port without change the cnf/ini file.

I just cought a case that cnf didn't work. It was weired... so I just use the cmd line as the shortcut and it works!

Find out which other service uses port 80.

I have heard skype uses port 80. Check it there isn't another server or database running in the background on port 80.

Two good alternatives to xampp are wamp and easyphp. Out of that, wamp is the most user friendly and it also has a built in tool for checking if port 80 is in use and which service is currently using it.

Or disable iis. It has been known to use port 80 by default.

the first step

netstat -vanp tcp | grep 8888

example

tcp4     0      0    127.0.0.1.8888   *.*    LISTEN      131072 131072  76061    0
tcp46    0      0    *.8888           *.*    LISTEN      131072 131072  50523    0

the second step: find your PIDs and kill them

in my case

sudo kill -9 76061 50523

How about netstat?

http://support.microsoft.com/kb/907980

The command is netstat -anob.

(Make sure you run command as admin)

I get:

C:\Windows\system32>netstat -anob

And If you want to check for the particular port, command to use is: netstat -aon | findstr 8080 from the same path

Ahem, because 22 is the port number for ssh and has been for ages?

You can get the port number by using server.address().port like in below code:

var http = require('http');
var serverFunction = function (req, res) {

    if (req.url == '/') {
        console.log('get method');
        res.writeHead(200, { 'content-type': 'text/plain' });
        res.end('Hello World');
    }

}
var server = http.createServer(serverFunction);
server.listen(3002, function () {
    console.log('server is listening on port:', server.address().port);
});

If you want your container ports to bind on your ipv4 address, just :

• find the settings file
  • /etc/sysconfig/docker-network on RedHat alike
  • /etc/default/docker-network on Debian ans alike
• edit the network settings
  • add DOCKER_NETWORK_OPTIONS=-ip=xx.xx.xx.xx
  • xx.xx.xx.xx being your real ipv4 (and not 0.0.0.0)
• restart docker deamon

works for me on docker 1.9.1

you can get loccalhost page by writing localhost/xampp or by writing http://127.0.0.1 you will get the local host page. After starting the apache serve that can be from wamp, xamp or lamp.

You'll need to add a firewall rule to open inbound access to tcp:9090 to your instances. If you have more than the two instances, and you only want to open 9090 to those two, you'll want to make sure that there is a tag that those two instances share. You can add or update tags via the console or the command-line; I'd recommend using the GUI for that if needed because it handles the read-modify-write cycle with setinstancetags.

If you want to open port 9090 to all instances, you can create a firewall rule like:

gcutil addfirewall allow-9090 --allowed=tcp:9090

which will apply to all of your instances.

If you only want to open port 9090 to the two instances that are serving your application, make sure that they have a tag like my-app, and then add a firewall like so:

gcutil addfirewall my-app-9090 --allowed=tcp:9090 --target_tags=my-app

You can read more about creating and managing firewalls in GCE here.

You have to edit postgresql.conf file and change line with 'listen_addresses'.

This file you can find in the /etc/postgresql/9.3/main directory.

Default Ubuntu config have allowed only localhost (or 127.0.0.1) interface, which is sufficient for using, when every PostgreSQL client work on the same computer, as PostgreSQL server. If you want connect PostgreSQL server from other computers, you have change this config line in this way:

listen_addresses = '*'

Then you have edit pg_hba.conf file, too. In this file you have set, from which computers you can connect to this server and what method of authentication you can use. Usually you will need similar line:

host    all         all         192.168.1.0/24        md5

Please, read comments in this file...

EDIT:

After the editing postgresql.conf and pg_hba.conf you have to restart postgresql server.

EDIT2: Highlited configuration files.

So it's throwing up that error message because you have apache2 running on port 80.

If this is for development, I would just leave it as it is on port 5000.

If it's for production either:

Not Recommended

• Stop apache2 first;

Not recommended as it states in the documentation:

You can use the builtin server during development, but you should use a full deployment option for production applications. (Do not use the builtin development server in production.)

Recommended

• Proxy HTTP traffic through apache2 to Flask.

This way, apache2 can handle all your static files (which it's very good at - much better than the debug server built into Flask) and act as a reverse proxy for your dynamic content, passing those requests to Flask.

Here's a link to the official documentation about setting up Flask with Apache + mod_wsgi.

Edit 1 - Clarification for @Djack

Proxy HTTP traffic to Flask through apache2

When a request comes to the server on port 80 (HTTP) or port 443 (HTTPS) a web server like Apache or Nginx handles the connection of the request and works out what to do with it. In our case a request received should be configured to be passed through to Flask on the WSGI protocol and handled by the Python code. This is the "dynamic" part.

reverse proxy for dynamic content

There are a few advantages to configuring your web server like the above;

• SSL Termination - The web server will be optimized to handle HTTPS requests with only a little configuration. Don't "roll your own" in Python which is probably very insecure in comparison.
• Security - Opening a port to the internet requires careful consideration of security. Flask's development server is not designed for this and could have open bugs or security issues in comparison to a web server designed for this purpose. Note that a badly configured web server can also be insecure!
• Static File Handling - It is possible for the builtin Flask web server to handle static files however this is not recommended; Nginx/Apache are much more efficient at handling static files like images, CSS, Javascript files and will only pass "dynamic" requests (those where the content is often read from a database or the content changes) to be handled by the Python code.
• +more. This is bordering on scope for this question. If you want more info do some research into this area.

There are couple of good free service that let you do the same. Ideal for showing something quickly for testing:

• http://localtunnel.me/
• https://ngrok.com/
• http://localhost.run/

Edits:

• add ngrok service
• add localhost.run service

Paying tribute to IgorBeaz, you need to stop running the current container. For that you are going to know current CONTAINER ID:

$ docker container ls

You get something like:

CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS                  NAMES

Then you stop the container by:

$ docker stop 12a32e8928ef

Finally you try to do what you wanted to do, for example:

$ docker run -p 4000:80 friendlyhello

1. Go to C:\xampp\phpMyAdmin

2. Edit the config.inc.php file

3. Replace $cfg['Servers'][$i]['auth_type'] = 'config'; by $cfg['Servers'][$i]['auth_type'] = 'cookie';

For now on the PHPMyAdmin will ask you for your password, no more error.

Port 465: IANA has reassigned a new service to this port, and it should no longer be used for SMTP communications.

However, because it was once recognized by IANA as valid, there may be legacy systems that are only capable of using this connection method. Typically, you will use this port only if your application demands it. A quick Google search, and you'll find many consumer ISP articles that suggest port 465 as the recommended setup. Hopefully this ends soon! It is not RFC compliant.

Port 587: This is the default mail submission port. When a mail client or server is submitting an email to be routed by a proper mail server, it should always use this port.

Everyone should consider using this port as default, unless you're explicitly blocked by your upstream network or hosting provider. This port, coupled with TLS encryption, will ensure that email is submitted securely and following the guidelines set out by the IETF.

Port 25: This port continues to be used primarily for SMTP relaying. SMTP relaying is the transmittal of email from email server to email server.

In most cases, modern SMTP clients (Outlook, Mail, Thunderbird, etc) shouldn't use this port. It is traditionally blocked, by residential ISPs and Cloud Hosting Providers, to curb the amount of spam that is relayed from compromised computers or servers. Unless you're specifically managing a mail server, you should have no traffic traversing this port on your computer or server.

use netstat -bano in an elevated command prompt to see what apps are listening on which ports.

But Usually following applications uses port 80 in windows.

1. IIS
2. World Wide Web Publishing service
3. IIS Admin Service
4. SQL Server Reporting services
5. Web Deployment Agent Service

Stop above applications if running and check!!!

netstat -a -n | find /c "10.240.199.9:8080"

it will give you number of sockets active on a specific IP and port(Server port number)

Use NETSTAT on the command-line:

netstat util

i have found that similar issue on my system, and that was from skype installed before xampp installed. i got similar error. for fixing the error i followed these,

1. logged out to skype for a while ,
2. restarted apache from xampp control panel,
3. checked on browser, whether it worked or not, by http://localhost/
4. got it worked,
5. signed in again to skype,
6. all working great, as simple as that

i wasn't need nothing to install or uninstall, and this worked for me in less then 1 minute.

cheers

A socket = IP Address + a port (numeric address)
Together they identify an end-point for a network connection on a machine. (Did I just flunk network 101?)

SOAP (communication protocol) for communication between applications. Uses HTTP (port 80) or SMTP ( port 25 or 2525 ), for message negotiation and transmission.

Follow the steps that are described on this answer just instead of using the drop down, type the port (8787) in "port range" an then "Add rule".

Go to the "Network & Security" -> Security Group settings in the left hand navigation

Find the Security Group that your instance is apart of Click on Inbound Rules Use the drop down and add HTTP (port 80) Click Apply and enjoy

PORT 4369: Erlang makes use of a Port Mapper Daemon (epmd) for resolution of node names in a cluster. Nodes must be able to reach each other and the port mapper daemon for clustering to work.

PORT 35197 set by inet_dist_listen_min/max Firewalls must permit traffic in this range to pass between clustered nodes

RabbitMQ Management console:

• PORT 15672 for RabbitMQ version 3.x
• PORT 55672 for RabbitMQ pre 3.x

PORT 5672 RabbitMQ main port.

For a cluster of nodes, they must be open to each other on 35197, 4369 and 5672.

For any servers that want to use the message queue, only 5672 is required.

We cannot change the application port from the avtivator but can change from the command line activator "~run 8080"

But to run on the poet 9000 from the activator we need to stop the application which is using this port. We can use the this application to find this and end the process https://technet.microsoft.com/en-in/sysinternals/bb897437.aspx

After this we can run and it will be successful.

I guess the problem is that you need to start a separate thread for each connection and call serverSocket.accept() in a loop to accept more than one connection.

It is not a problem to have more than one connection on the same port.

The default port of Postgres is commonly configured in:

sudo vi /<path to your installation>/data/postgresql.conf

On Ubuntu this might be:

sudo vi /<path to your installation>/main/postgresql.conf

Search for port in this file.

The default port for SQL Server Database Engine is 1433.

And as a best practice it should always be changed after the installation. 1433 is widely known which makes it vulnerable to attacks.

In my case this issue caused because my local machine used to the one MySQL service installed earlier at 3006 port. Thus I modified both my.ini (C:\xampp\mysql\bin\my.ini) and php.ini (C:\xampp\php\php.ini) files replaced port 3006 to 3008

After that I've created a new service running the command described above by Tommer:

sc.exe create "mysqlweb" binPath= "C:\xampp\mysql\bin\mysqld.exe --defaults-file=c:\xampp\mysql\bin\my.ini mysqlweb"

A connected socket is assigned to a new (dedicated) port

That's a common intuition, but it's incorrect. A connected socket is not assigned to a new/dedicated port. The only actual constraint that the TCP stack must satisfy is that the tuple of (local_address, local_port, remote_address, remote_port) must be unique for each socket connection. Thus the server can have many TCP sockets using the same local port, as long as each of the sockets on the port is connected to a different remote location.

See the "Socket Pair" paragraph at: http://books.google.com/books?id=ptSC4LpwGA0C&lpg=PA52&dq=socket%20pair%20tuple&pg=PA52#v=onepage&q=socket%20pair%20tuple&f=false

Yes and no. Only one application can actively listen on a port. But that application can bequeath its connection to another process. So you could have multiple processes working on the same port.

we an use handy tools like ssh to accomplish this easily.

I was using ubuntu host and ubuntu based docker image.

1. Inside docker have openssh-client installed.
2. Outside docker (host) have openssh-server server installed.

when a new port is needed to be mapped out,

inside the docker run the following command

ssh -R8888:localhost:8888 <username>@172.17.0.1

172.17.0.1 was the ip of the docker interface (you can get this by running ifconfig docker0 | grep "inet addr" | cut -f2 -d":" | cut -f1 -d" " on the host).

here I had local 8888 port mapped back to the hosts 8888. you can change the port as needed.

if you need one more port, you can kill the ssh and add one more line of -R to it with the new port.

I have tested this with netcat.

The following configs works on Cent OS 6 or earlier

As stated above first have to disable selinux.

Step 1 nano /etc/sysconfig/selinux

Make sure the file has this configurations

SELINUX=disabled

SELINUXTYPE=targeted

Then restart the system

Step 2

iptables -A INPUT -m state --state NEW -p tcp --dport 8080 -j ACCEPT

Step 3

sudo service iptables save

For Cent OS 7

step 1

firewall-cmd --zone=public --permanent --add-port=8080/tcp

Step 2

firewall-cmd --reload

I tried to improve the suggestion from mshutov. I added the option to use the output as an object.

 function Test-Port($hostname, $port)
    {
    # This works no matter in which form we get $host - hostname or ip address
    try {
        $ip = [System.Net.Dns]::GetHostAddresses($hostname) | 
            select-object IPAddressToString -expandproperty  IPAddressToString
        if($ip.GetType().Name -eq "Object[]")
        {
            #If we have several ip's for that address, let's take first one
            $ip = $ip[0]
        }
    } catch {
        Write-Host "Possibly $hostname is wrong hostname or IP"
        return
    }
    $t = New-Object Net.Sockets.TcpClient
    # We use Try\Catch to remove exception info from console if we can't connect
    try
    {
        $t.Connect($ip,$port)
    } catch {}

    if($t.Connected)
    {
        $t.Close()
        $object = [pscustomobject] @{
                        Hostname = $hostname
                        IP = $IP
                        TCPPort = $port
                        GetResponse = $True }
        Write-Output $object
    }
    else
    {
        $object = [pscustomobject] @{
                        Computername = $IP
                        TCPPort = $port
                        GetResponse = $False }
        Write-Output $object

    }
    Write-Host $msg
}

I assume you're talking about the Apache server that Oracle installs. Look for the file httpd.conf.

Open this file in a text editor and look for the line
Listen 8080
or
Listen {ip address}:8080

Change the port number and either restart the web server or just reboot the machine.

It's easy enough to do with the -z and -w TIMEOUT options to nc, but not all systems have nc installed. If you have a recent enough version of bash, this will work:

# Connection successful:
$ timeout 1 bash -c 'cat < /dev/null > /dev/tcp/google.com/80'
$ echo $?
0

# Connection failure prior to the timeout
$ timeout 1 bash -c 'cat < /dev/null > /dev/tcp/sfsfdfdff.com/80'
bash: sfsfdfdff.com: Name or service not known
bash: /dev/tcp/sfsfdfdff.com/80: Invalid argument
$ echo $?
1

# Connection not established by the timeout
$ timeout 1 bash -c 'cat < /dev/null > /dev/tcp/google.com/81'
$ echo $?
124

What's happening here is that timeout will run the subcommand and kill it if it doesn't exit within the specified timeout (1 second in the above example). In this case bash is the subcommand and uses its special /dev/tcp handling to try and open a connection to the server and port specified. If bash can open the connection within the timeout, cat will just close it immediately (since it's reading from /dev/null) and exit with a status code of 0 which will propagate through bash and then timeout. If bash gets a connection failure prior to the specified timeout, then bash will exit with an exit code of 1 which timeout will also return. And if bash isn't able to establish a connection and the specified timeout expires, then timeout will kill bash and exit with a status of 124.

None of these answers seem to completely address the question, which calls for an arbitrary url, not specifically the url of the current page.

Method 1: Use the URL API (caveat: no IE11 support)

You can use the URL API (not supported by IE11, but available everywhere else).

This also makes it easy to access search params. Another bonus: it can be used in a Web Worker since it doesn't depend on the DOM.

const url = new URL('http://example.com:12345/blog/foo/bar?startIndex=1&pageSize=10');

Method 2 (old way): Use the browser's built-in parser in the DOM

Use this if you need this to work on older browsers as well.

//  Create an anchor element (note: no need to append this element to the document)
const url = document.createElement('a');
//  Set href to any path
url.setAttribute('href', 'http://example.com:12345/blog/foo/bar?startIndex=1&pageSize=10');

That's it!

The browser's built-in parser has already done its job. Now you can just grab the parts you need (note that this works for both methods above):

//  Get any piece of the url you're interested in
url.hostname;  //  'example.com'
url.port;      //  12345
url.search;    //  '?startIndex=1&pageSize=10'
url.pathname;  //  '/blog/foo/bar'
url.protocol;  //  'http:'

Bonus: Search params

Chances are you'll probably want to break apart the search url params as well, since '?startIndex=1&pageSize=10' isn't too useable on its own.

If you used Method 1 (URL API) above, you simply use the searchParams getters:

url.searchParams.get('startIndex');  // '1'

Or to get all parameters:

function searchParamsToObj(searchParams) {
  const paramsMap = Array
    .from(url.searchParams)
    .reduce((params, [key, val]) => params.set(key, val), new Map());
  return Object.fromEntries(paramsMap);
}
searchParamsToObj(url.searchParams);
// -> { startIndex: '1', pageSize: '10' }

If you used Method 2 (the old way), you can use something like this:

// Simple object output (note: does NOT preserve duplicate keys).
var params = url.search.substr(1); // remove '?' prefix
params
    .split('&')
    .reduce((accum, keyval) => {
        const [key, val] = keyval.split('=');
        accum[key] = val;
        return accum;
    }, {});
// -> { startIndex: '1', pageSize: '10' }

I... don't think so. You can redirect the subdomain (such as blah.something.com) to point to something.com:25566, but I don't think you can actually set up the subdomain to be on a different port like that. I could be wrong, but it'd probably be easier to use a simple .htaccess or something to check %{HTTP_HOST} and redirect according to the subdomain.

There are a lot of options and tools. If you just want a list of listening ports and their owner processes try.

netstat -bano

I have solved this problem because the MongoDB or there is another app u had run it before on this port, so to solve it kill the process from task manager, or just change the number of the port from 3000 to any other one.

A single listening port can accept more than one connection simultaneously.

There is a '64K' limit that is often cited, but that is per client per server port, and needs clarifying.

Each TCP/IP packet has basically four fields for addressing. These are:

source_ip source_port destination_ip destination_port
<----- client ------> <--------- server ------------>

Inside the TCP stack, these four fields are used as a compound key to match up packets to connections (e.g. file descriptors).

If a client has many connections to the same port on the same destination, then three of those fields will be the same - only source_port varies to differentiate the different connections. Ports are 16-bit numbers, therefore the maximum number of connections any given client can have to any given host port is 64K.

However, multiple clients can each have up to 64K connections to some server's port, and if the server has multiple ports or either is multi-homed then you can multiply that further.

So the real limit is file descriptors. Each individual socket connection is given a file descriptor, so the limit is really the number of file descriptors that the system has been configured to allow and resources to handle. The maximum limit is typically up over 300K, but is configurable e.g. with sysctl.

The realistic limits being boasted about for normal boxes are around 80K for example single threaded Jabber messaging servers.

When hosting your application on another service (like Heroku, Nodejitsu, and AWS), your host may independently configure the process.env.PORT variable for you; after all, your script runs in their environment.

Amazon's Elastic Beanstalk does this. If you try to set a static port value like 3000 instead of process.env.PORT || 3000 where 3000 is your static setting, then your application will result in a 500 gateway error because Amazon is configuring the port for you.

This is a minimal Express application that will deploy on Amazon's Elastic Beanstalk:

var express = require('express');
var app = express();

app.get('/', function (req, res) {
  res.send('Hello World!');
});

// use port 3000 unless there exists a preconfigured port
var port = process.env.PORT || 3000;

app.listen(port);

You need to edit your ~/.ssh/config file. Add something like the following:

Host example.com
    Port 1234

A quick google search shows a few different resources that explain it in more detail than me.

If your server starts up, then that socket was not used.

EDIT

Something like:

ServerSocket s = null ;

try { 
    s = new ServerSocket( 0 ); 
} catch( IOException ioe ){
   for( int i = START; i < END ; i++ ) try {
        s = new ServerSocket( i );
    } catch( IOException ioe ){}
}
// At this point if s is null we are helpless
if( s == null ) {
    throw new IOException(
       Strings.format("Unable to open server in port range(%d-%d)",START,END));
}

So here is the solution for this:

I check port 80 used by Skype, after that I changes port to 81 and also along with that somewhere i read this error may be because of SSL Port then I changed SSL port to 444. However this got resolved easily.

One most important thing to notice here, all the port changes should be done inside config files, for http port change: httpd.conf for SSL httpd-ssl.conf. Otherwise changes will not replicate to Apache, Sometime PC reboot is also required.

Edit: Make Apache use port 80 and make Skype communicate on other Port

For those who are struggling with Skype, want to change its port and to make Apache to use port 80.

No need to Re-Install, Here is simply how to change Skype Port

Goto: Tools > Options > Advanced > Connection

There you need to uncheck Use port 80 and 443 as alternative for incoming connections.

That's it, here is screen shot of it.

As the others have said, you'll have to kill all processes that are listening on that port. The easiest way to do that would be to use the fuser(1) command. For example, to see all of the processes listening for http requests on port 80 (run as root or use sudo):

# fuser 80/tcp

If you want to kill them, then just add the -k option.

localhost seemed to be working fine in my emulator at start and then i started getting connection refused exception i used 127.0.2.2 from the emulator browser and it worked and when i used this in my android app in emulator it again started showing the connection refused problem.

then i did ifconfig and i used the ip 192.168.2.2 and it worked perfectly

We had a similar situation, but in our case Infosec agreed to allow any to 1, so we didnt had to fix the slave port, rather fixing the master to high level JNLP port 49187 worked ("Configure Global Security" -> "TCP port for JNLP slave agents").

TCP
49187 - Fixed jnlp port
8080 - jenkins http port

Other ports needed to launch slave as a windows service

TCP
135 
139 
445

UDP
137
138

Another utility that I found and is good and small as well, is PortQry Command Line Port Scanner version 2.0.

You can ping a server and a port and it will tell you the state of the port. There is a command-line utility and a UI for it.

An other service that could occupied the port 80 is BranchCache

services.msc showing it as "BranchCache"

or use the net command to stop the service like

net stop PeerDistSvc

Update:

PeerDistSvc is a service behind svhost.exe, to view svchost services type

tasklist /svc /fi "imagename eq svchost.exe"

There are many answers, but you should just be able to keep it simple. Make sure you know what port SSH is listening on, and define it. Here is what I just used to replicate your problem.

scp -P 12222 file.7z [email protected]:/home/user/Downloads It worked out well.

Your port 80 is being used by the system.

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

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

You need to edit the Tomcat/conf/server.xml and change the connector port. The connector setting should look something like this:

<Connector port="8080" maxHttpHeaderSize="8192"
           maxThreads="150" minSpareThreads="25" maxSpareThreads="75"
           enableLookups="false" redirectPort="8443" acceptCount="100"
           connectionTimeout="20000" disableUploadTimeout="true" />

Just change the connector port from default 8080 to another valid port number.

To view open ports, use the following command.

firewall-cmd --list-ports

We use the following to see services whose ports are open.

firewall-cmd --list-services

We use the following to see services whose ports are open and see open ports

firewall-cmd --list-all

To add a service to the firewall, we use the following command, in which case the service will use any port to open in the firewall.

firewall-cmd --add-services=ntp 

For this service to be permanently open we use the following command.

firewall-cmd —add-service=ntp --permanent 

To add a port, use the following command

firewall-cmd --add-port=132/tcp  --permanent

To run the firewall must be reloaded using the following command.

firewall-cmd --reload

It appears that as of Java 7, David Santamaria's answer doesn't work reliably any more. It looks like you can still reliably use a Socket to test the connection, however.

private static boolean available(int port) {
    System.out.println("--------------Testing port " + port);
    Socket s = null;
    try {
        s = new Socket("localhost", port);

        // If the code makes it this far without an exception it means
        // something is using the port and has responded.
        System.out.println("--------------Port " + port + " is not available");
        return false;
    } catch (IOException e) {
        System.out.println("--------------Port " + port + " is available");
        return true;
    } finally {
        if( s != null){
            try {
                s.close();
            } catch (IOException e) {
                throw new RuntimeException("You should handle this error." , e);
            }
        }
    }
}

to build on what @veer7 said:

if you want to know what was on the port, do this before you kill it.

$ sudo netstat -plten |grep java
tcp6       0      0 127.0.0.1:8005          :::*                    LISTEN      1000       906726      25296/java      
tcp6       0      0 :::8009                 :::*                    LISTEN      1000       907503      25296/java      
tcp6       0      0 :::8080                 :::*                    LISTEN      1000       907499      25296/java      
$ ps 25296
  PID TTY      STAT   TIME COMMAND
25296 ?        Sl     0:16 /usr/lib/jvm/java-8-openjdk-amd64/bin/java -Dcatalina.base=/hom

Use 'ps' and the number of the process that netstat reported back

There's a native GUI for Windows:

• Start menu → All Programs → Accessories → System Tools → Resource Monitor

Or Run resmon.exe, or from Task Manager's performance tab.

Well you can disable skype to use port 80. Click tools --> Options --> Advanced --> Connection and uncheck the appropriate checkbox.

I also read the answers and comments and tried some solutions from this thread.

Then a Googled a little more and this worked for me

https://www.c-sharpcorner.com/blogs/iis-express-failed-to-register-url-access-is-denied

Didn't comment on no one's answer because I didn't read whats written here, so it needed a new answer post. There's answers here that talk about netsh wlan stuff, but I didn't see exactly this solution. If some one wrote the exact same solution please tell me so I can comment there and remove this.

If you really need to do this, use reverse proxy.

For example, with nginx as reverse proxy

server {
  listen       api.mydomain.com:80;
  server_name  api.mydomain.com;
  location / {
    proxy_pass http://127.0.0.1:8000;
  }
}

on windows, the netstat option to get the pid's is -o and -p selects a protocol filter, ex.: netstat -a -p tcp -o

Am Using windows Operating system.

I killed all the node process and restarted the app it worked.

try

taskkill /im node.exe

According to this link

Actually, SO_REUSEADDR flag can lead to much greater consequences: SO_REUSADDR permits you to use a port that is stuck in TIME_WAIT, but you still can not use that port to establish a connection to the last place it connected to. What? Suppose I pick local port 1010, and connect to foobar.com port 300, and then close locally, leaving that port in TIME_WAIT. I can reuse local port 1010 right away to connect to anywhere except for foobar.com port 300.

However you can completely avoid TIME_WAIT state by ensuring that the remote end initiates the closure (close event). So the server can avoid problems by letting the client close first. The application protocol must be designed so that the client knows when to close. The server can safely close in response to an EOF from the client, however it will also need to set a timeout when it is expecting an EOF in case the client has left the network ungracefully. In many cases simply waiting a few seconds before the server closes will be adequate.

I also advice you to learn more about networking and network programming. You should now at least how tcp protocol works. The protocol is quite trivial and small and hence, may save you a lot of time in future.

With netstat command you can easily see which programs ( (program_name,pid) tuple) are binded to which ports and what is the socket current state: TIME_WAIT, CLOSING, FIN_WAIT and so on.

A really good explanation of linux network configurations can be found https://serverfault.com/questions/212093/how-to-reduce-number-of-sockets-in-time-wait.

You can also use this first command to kill a process that owns a particular port:

sudo netstat -ap | grep :<port_number>

For example, say this process holds port 8000 TCP, then running the command:

sudo netstat -ap | grep :8000

will output the line corresponding to the process holding port 8000, for example:

tcp  0  0 *:8000   *:* LISTEN  4683/procHoldingPort

In this case, procHoldingPort is the name of the process that opened the port, 4683 is its pid, and 8000 (note that it is TCP) is the port number it holds (which you wish to close).

Then kill the process, following the above example:

kill  4683

As others mentioned here out, if that doesn't work (you can try using kill with -9 as an argument):

kill -9 4683

Again, in general, it's better to avoid sending SIGKILL (-9) if you can.

This worked for me :

Added a custom container class :

@Component
public class CustomContainer implements EmbeddedServletContainerCustomizer {

    @Override
    public void customize(ConfigurableEmbeddedServletContainer configurableEmbeddedServletContainer) {
       configurableEmbeddedServletContainer.setPort(8888);
    }

}

But this was still not using port 8888.

Then I set "scanBasePackages" property like this on "@SpringBootApplication" class on my main method: (scanBasePackages = {"custom container package"})

@SpringBootApplication(scanBasePackages = {"com.javabrains.util"})
public class CourseApiApp {

    public static void main (String args []) {
        SpringApplication.run(CourseApiApp.class, args);
    }
}

And it started picking up port set in Custom Container.

For the sake of snippet of what the guys have explained above:

import socket
from contextlib import closing

def find_free_port():
    with closing(socket.socket(socket.AF_INET, socket.SOCK_STREAM)) as s:
        s.bind(('', 0))
        s.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
        return s.getsockname()[1]

Just change the port 80 to anything else like 8080(in httpd.conf), and port 443 to something else like 4433 (in httpd-ssl.conf)

In bin/www, there is a line:

var port = normalizePort(process.env.PORT || '3000');

Try to modify it.

You can get the server port from the

HttpServletRequest

@Autowired
private HttpServletRequest request;

@GetMapping(value = "/port")
public Object getServerPort() {
   System.out.println("I am from " + request.getServerPort());
   return "I am from  " + request.getServerPort();
}
    

First off, a "port" is just a number. All a "connection to a port" really represents is a packet which has that number specified in its "destination port" header field.

Now, there are two answers to your question, one for stateful protocols and one for stateless protocols.

For a stateless protocol (ie UDP), there is no problem because "connections" don't exist - multiple people can send packets to the same port, and their packets will arrive in whatever sequence. Nobody is ever in the "connected" state.

For a stateful protocol (like TCP), a connection is identified by a 4-tuple consisting of source and destination ports and source and destination IP addresses. So, if two different machines connect to the same port on a third machine, there are two distinct connections because the source IPs differ. If the same machine (or two behind NAT or otherwise sharing the same IP address) connects twice to a single remote end, the connections are differentiated by source port (which is generally a random high-numbered port).

Simply, if I connect to the same web server twice from my client, the two connections will have different source ports from my perspective and destination ports from the web server's. So there is no ambiguity, even though both connections have the same source and destination IP addresses.

Ports are a way to multiplex IP addresses so that different applications can listen on the same IP address/protocol pair. Unless an application defines its own higher-level protocol, there is no way to multiplex a port. If two connections using the same protocol simultaneously have identical source and destination IPs and identical source and destination ports, they must be the same connection.

A simple but relatively insecure way would be to use the --net=host option to docker run.

This option makes it so that the container uses the networking stack of the host. Then you can connect to services running on the host simply by using "localhost" as the hostname.

This is easier to configure because you won't have to configure the service to accept connections from the IP address of your docker container, and you won't have to tell the docker container a specific IP address or host name to connect to, just a port.

For example, you can test it out by running the following command, which assumes your image is called my_image, your image includes the telnet utility, and the service you want to connect to is on port 25:

docker run --rm -i -t --net=host my_image telnet localhost 25

If you consider doing it this way, please see the caution about security on this page:

https://docs.docker.com/articles/networking/

It says:

--net=host -- Tells Docker to skip placing the container inside of a separate network stack. In essence, this choice tells Docker to not containerize the container's networking! While container processes will still be confined to their own filesystem and process list and resource limits, a quick ip addr command will show you that, network-wise, they live “outside” in the main Docker host and have full access to its network interfaces. Note that this does not let the container reconfigure the host network stack — that would require --privileged=true — but it does let container processes open low-numbered ports like any other root process. It also allows the container to access local network services like D-bus. This can lead to processes in the container being able to do unexpected things like restart your computer. You should use this option with caution.

Cities of the world database donated by MaxMind.com

The company MaxMind.com1 has agreed to release their cities of the world database under the GPL. The database contains locations by country, city, latitude and longitude. There are over 3,047,000 records in the database. For those of you who have tried the location.module with the zipcodes database from CivicSpace, you will recognize how cool it is and how well this fits with that project and therefore Drupal.

Here's another free one that might help you get started.

Creating and maintaining such a database is quite a bit of work - so anyone who's done it is likely keeping it to themselves, or offering it for a fee.

This is also coming when you apply a constant in PHP to the empty() function:

if (!empty(SOME_CONSTANT)) {

}

That was my case. I solved it by using this:

$string = SOME_CONSTANT;
if (!empty($string)) {

}

You've simply got it backwards. Specifying a minimum width would make the select menu always be at least that width, so it will continue expanding to 90% no matter what the window size is, also being at least the size of its longest option.

You need to use max-width instead. This way, it will let the select menu expand to its longest option, but if that expands past your set maximum of 90% width, crunch it down to that width.

Take a look at your code :

 getUsers(): Observable<User[]> {
        return Observable.create(observer => {
            this.http.get('http://users.org').map(response => response.json();
        })
    }

and code from https://angular.io/docs/ts/latest/tutorial/toh-pt6.html (BTW. really good tutorial, you should check it out)

 getHeroes(): Promise<Hero[]> {
    return this.http.get(this.heroesUrl)
               .toPromise()
               .then(response => response.json().data as Hero[])
               .catch(this.handleError);
  }

The HttpService inside Angular2 already returns an observable, sou don't need to wrap another Observable around like you did here:

   return Observable.create(observer => {
        this.http.get('http://users.org').map(response => response.json()

Try to follow the guide in link that I provided. You should be just fine when you study it carefully.

---EDIT----

First of all WHERE you log the this.users variable? JavaScript isn't working that way. Your variable is undefined and it's fine, becuase of the code execution order!

Try to do it like this:

  getUsers(): void {
        this.userService.getUsers()
            .then(users => {
               this.users = users
               console.log('this.users=' + this.users);
            });


    }

See where the console.log(...) is!

There are a couple of variants of a rename command, in your case, it may be as simple as

rename ABC XYZ *.dat

You may have a version which takes a Perl regex;

rename 's/ABC/XYZ/' *.dat

This is a fairly trivial effect to accomplish. One way to achieve this is to simply place floated div elements within a common parent container, and set their width and height. In order to clear the floated elements, we set the overflow property of the parent.

<div class="container">
    <div class="cube">do</div>
    <div class="cube">ray</div>
    <div class="cube">me</div>
    <div class="cube">fa</div>
    <div class="cube">so</div>
    <div class="cube">la</div>
    <div class="cube">te</div>
    <div class="cube">do</div>
</div>

The CSS resembles the strategy outlined in the first paragraph above:

.container {
    width: 450px;
    overflow: auto;
}

.cube {
    float: left;
    width: 150px; 
    height: 150px;
}

You can see the end result here: http://jsfiddle.net/Qjum2/2/

Browsers that support pseudo elements provide an alternative way to clear:

.container::after {
    content: "";
    clear: both;
    display: block;
}

You can see the results here: http://jsfiddle.net/Qjum2/3/

I hope this helps.

A one-line version of this excellent answer to plot the line of best fit is:

plt.plot(np.unique(x), np.poly1d(np.polyfit(x, y, 1))(np.unique(x)))

Using np.unique(x) instead of x handles the case where x isn't sorted or has duplicate values.

Another way to understand it is to figure out what error code it eliminates by having attr_accessor.

Example:

class BankAccount    
  def initialize( account_owner )
    @owner = account_owner
    @balance = 0
  end

  def deposit( amount )
    @balance = @balance + amount
  end

  def withdraw( amount )
    @balance = @balance - amount
  end
end

The following methods are available:

$ bankie = BankAccout.new("Iggy")
$ bankie 
$ bankie.deposit(100)
$ bankie.withdraw(5)

The following methods throws error:

$ bankie.owner     #undefined method `owner'... 
$ bankie.balance   #undefined method `balance'...

owner and balance are not, technically, a method, but an attribute. BankAccount class does not have def owner and def balance. If it does, then you can use the two commands below. But those two methods aren't there. However, you can access attributes as if you'd access a method via attr_accessor!! Hence the word attr_accessor. Attribute. Accessor. It accesses attributes like you would access a method.

Adding attr_accessor :balance, :owner allows you to read and write balance and owner "method". Now you can use the last 2 methods.

$ bankie.balance
$ bankie.owner

I faced the same issue with jdk1.8.0_201.It got resolved when I made JAVA_HOME=C:\Program Files\Java\jdk1.8.0_201 and added "C:\Program Files\Java\jdk1.8.0_201\bin" in path variable

The simplest way is:

String someNum = "123000";
System.out.println(someNum);

My reason was having same library with different snapshot versions in WEB-INF/lib:

some-lib-3.14.0.143-SNAPSHOT.jar

To fix the issue remove redundant copy.

I have started writing one tutorial for everyone on this topic, see making gadgets for Windows 7.

Using find and replace will work if you type "null" in the find and put a zero in the replace...you will be warned that this cannot be undone.

myArray.sample

will return 1 random value.

myArray.shuffle.first

will also return 1 random value.

Personally none of the above worked for me. What did:

new_str = [str(x) for x in old_obj][0]

Here is the only solution that worked for me:

http://www.hanewin.net/encrypt/aes/aes.htm

It's pretty basic, but simple to use and seems to work well.

Assuming you only want to disallow strings that match the regex completely (i.e., mmbla is okay, but mm isn't), this is what you want:

^(?!(?:m{2}|t)$).*$

(?!(?:m{2}|t)$) is a negative lookahead; it says "starting from the current position, the next few characters are not mm or t, followed by the end of the string." The start anchor (^) at the beginning ensures that the lookahead is applied at the beginning of the string. If that succeeds, the .* goes ahead and consumes the string.

FYI, if you're using Java's matches() method, you don't really need the the ^ and the final $, but they don't do any harm. The $ inside the lookahead is required, though.

you can extract only text from HTML with BeautifulSoup

url = "https://www.geeksforgeeks.org/extracting-email-addresses-using-regular-expressions-python/"
con = urlopen(url).read()
soup = BeautifulSoup(con,'html.parser')
texts = soup.get_text()
print(texts)

Use Integer.compare(int, int). And don'try to micro-optimize your code unless you can prove that you have a performance issue.

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

 <span class="hidden-xs" style="background: url(particular_ad.png)"></span>
 <span class="visible-xs" style="background: url(particular_ad_small.png)"></span>

No behaviors can be set by CSS. The only way to disable something in CSS is to make it invisible by either setting display:none or simply putting div with transparent img all over it and changing their z-orders to disable user focusing on it with mouse. Even though, user will still be able to focus with tab from another field.

You need to use df.shift here.
df.shift(i) shifts the entire dataframe by i units down.

So, for i = 1:

Input:

    x1   x2  
0  206  214  
1  226  234  
2  245  253  
3  265  272    
4  283  291

Output:

    x1   x2
0  Nan  Nan   
1  206  214  
2  226  234  
3  245  253  
4  265  272 

So, run this script to get the expected output:

import pandas as pd

df = pd.DataFrame({'x1': ['206', '226', '245',' 265', '283'],
                   'x2': ['214', '234', '253', '272', '291']})

print(df)
df['x2'] = df['x2'].shift(1)
print(df)

Specially for Android

For callback purposes I usually implement my own generic Runnable with input parameter(s):

public interface Runnable<TResult> {
    void run(TResult result);
}

Usage is simple:

myManager.doCallbackOperation(new Runnable<MyResult>() {
    @Override
    public void run(MyResult result) {
        // do something with the result
    }
});

In manager:

public void doCallbackOperation(Runnable<MyResult> runnable) {
    new AsyncTask<Void, Void, MyResult>() {
        @Override
        protected MyResult doInBackground(Void... params) {
            // do background operation
            return new MyResult(); // return resulting object
        }

        @Override
        protected void onPostExecute(MyResult result) {
            // execute runnable passing the result when operation has finished
            runnable.run(result);
        }
    }.execute();
}

You're missing #include <stdlib.h>.

Session class has been removed on SDK 4.0. The login magement is done through the class LoginManager. So:

mLoginManager = LoginManager.getInstance();
mLoginManager.logOut();

As the reference Upgrading to SDK 4.0 says:

Session Removed - AccessToken, LoginManager and CallbackManager classes supercede and replace functionality in the Session class.

Maybe you have added class with some "FirstNameClass" and after that manually rename to "ColoredDotView". Try to copy content of "ColoredDotView" class to clipboard, remove "ColoredDotView" from project and add agin.

This id fix similar problem from me.

At the bottom of this answer is an example of GLSL code which allows to output the full float value as color, encoding IEEE 754 binary32. I use it like follows (this snippet gives out yy component of modelview matrix):

vec4 xAsColor=toColor(gl_ModelViewMatrix[1][1]);
if(bool(1)) // put 0 here to get lowest byte instead of three highest
    gl_FrontColor=vec4(xAsColor.rgb,1);
else
    gl_FrontColor=vec4(xAsColor.a,0,0,1);

After you get this on screen, you can just take any color picker, format the color as HTML (appending 00 to the rgb value if you don't need higher precision, and doing a second pass to get the lower byte if you do), and you get the hexadecimal representation of the float as IEEE 754 binary32.

Here's the actual implementation of toColor():

const int emax=127;
// Input: x>=0
// Output: base 2 exponent of x if (x!=0 && !isnan(x) && !isinf(x))
//         -emax if x==0
//         emax+1 otherwise
int floorLog2(float x)
{
    if(x==0.) return -emax;
    // NOTE: there exist values of x, for which floor(log2(x)) will give wrong
    // (off by one) result as compared to the one calculated with infinite precision.
    // Thus we do it in a brute-force way.
    for(int e=emax;e>=1-emax;--e)
        if(x>=exp2(float(e))) return e;
    // If we are here, x must be infinity or NaN
    return emax+1;
}

// Input: any x
// Output: IEEE 754 biased exponent with bias=emax
int biasedExp(float x) { return emax+floorLog2(abs(x)); }

// Input: any x such that (!isnan(x) && !isinf(x))
// Output: significand AKA mantissa of x if !isnan(x) && !isinf(x)
//         undefined otherwise
float significand(float x)
{
    // converting int to float so that exp2(genType) gets correctly-typed value
    float expo=float(floorLog2(abs(x)));
    return abs(x)/exp2(expo);
}

// Input: x\in[0,1)
//        N>=0
// Output: Nth byte as counted from the highest byte in the fraction
int part(float x,int N)
{
    // All comments about exactness here assume that underflow and overflow don't occur
    const float byteShift=256.;
    // Multiplication is exact since it's just an increase of exponent by 8
    for(int n=0;n<N;++n)
        x*=byteShift;

    // Cut higher bits away.
    // $q \in [0,1) \cap \mathbb Q'.$
    float q=fract(x);

    // Shift and cut lower bits away. Cutting lower bits prevents potentially unexpected
    // results of rounding by the GPU later in the pipeline when transforming to TrueColor
    // the resulting subpixel value.
    // $c \in [0,255] \cap \mathbb Z.$
    // Multiplication is exact since it's just and increase of exponent by 8
    float c=floor(byteShift*q);
    return int(c);
}

// Input: any x acceptable to significand()
// Output: significand of x split to (8,8,8)-bit data vector
ivec3 significandAsIVec3(float x)
{
    ivec3 result;
    float sig=significand(x)/2.; // shift all bits to fractional part
    result.x=part(sig,0);
    result.y=part(sig,1);
    result.z=part(sig,2);
    return result;
}

// Input: any x such that !isnan(x)
// Output: IEEE 754 defined binary32 number, packed as ivec4(byte3,byte2,byte1,byte0)
ivec4 packIEEE754binary32(float x)
{
    int e = biasedExp(x);
    // sign to bit 7
    int s = x<0. ? 128 : 0;

    ivec4 binary32;
    binary32.yzw=significandAsIVec3(x);
    // clear the implicit integer bit of significand
    if(binary32.y>=128) binary32.y-=128;
    // put lowest bit of exponent into its position, replacing just cleared integer bit
    binary32.y+=128*int(mod(float(e),2.));
    // prepare high bits of exponent for fitting into their positions
    e/=2;
    // pack highest byte
    binary32.x=e+s;

    return binary32;
}

vec4 toColor(float x)
{
    ivec4 binary32=packIEEE754binary32(x);
    // Transform color components to [0,1] range.
    // Division is inexact, but works reliably for all integers from 0 to 255 if
    // the transformation to TrueColor by GPU uses rounding to nearest or upwards.
    // The result will be multiplied by 255 back when transformed
    // to TrueColor subpixel value by OpenGL.
    return vec4(binary32)/255.;
}

It's just a namespace definition to avoid collision of class names. The com.domain.package.Class is an established Java convention wherein the namespace is qualified with the company domain in reverse.

The ANSI SQL answer is FETCH FIRST.

SELECT a.names,
         COUNT(b.post_title) AS num
    FROM wp_celebnames a
    JOIN wp_posts b ON INSTR(b.post_title, a.names) > 0
    WHERE b.post_date > DATE_SUB(CURDATE(), INTERVAL 1 DAY)
GROUP BY a.names
ORDER BY num DESC
FETCH FIRST 10 ROWS ONLY

If you want ties to be included, do FETCH FIRST 10 ROWS WITH TIES instead.

To skip a specified number of rows, use OFFSET, e.g.

...
ORDER BY num DESC
OFFSET 20
FETCH FIRST 10 ROWS ONLY

Will skip the first 20 rows, and then fetch 10 rows.

Supported by newer versions of Oracle, PostgreSQL, MS SQL Server, Mimer SQL and DB2 etc.

here is a solution if you are not using jquery:

myArray = myArray.filter(function( obj ) {
  return obj.id !== id;
});

With formatting

require 'json'
tempHash = {
    "key_a" => "val_a",
    "key_b" => "val_b"
}
File.open("public/temp.json","w") do |f|
  f.write(JSON.pretty_generate(tempHash))
end

Output

{
    "key_a":"val_a",
    "key_b":"val_b"
}

With Node 0.12, it's possible to do this synchronously now:

  var fs = require('fs');
  var path = require('path');

  // Buffer mydata
  var BUFFER = bufferFile('../public/mydata.png');

  function bufferFile(relPath) {
    return fs.readFileSync(path.join(__dirname, relPath)); // zzzz....
  }

fs is the file system. readFileSync() returns a Buffer, or string if you ask.

fs correctly assumes relative paths are a security issue. path is a work-around.

To load as a string, specify the encoding:

return fs.readFileSync(path,{ encoding: 'utf8' });

you can create addHeaderView and use

adapter.addHeaderView(View).

This code build the addHeaderView for more then one header. the headers should have:

android:layout_height="wrap_content"

public class MyAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder> {
    private static final int TYPE_ITEM = -1;
    public class MyViewSHolder extends RecyclerView.ViewHolder {
        public MyViewSHolder (View view) {
            super(view);
        }
        // put you code. for example:
        View mView;
        ...
    }

    public class ViewHeader extends RecyclerView.ViewHolder {
        public ViewHeader(View view) {
            super(view);
        }
    }

    private List<View> mHeaderViews = new ArrayList<>();
    public void addHeaderView(View headerView) {
        mHeaderViews.add(headerView);
    }

    @Override
    public int getItemCount() {
       return ... + mHeaderViews.size();
    }

    @Override
    public int getItemViewType(int position) {
        if (mHeaderViews.size() > position) {
            return position;
        }

        return TYPE_ITEM;
    }
    @Override
    public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        if (viewType != TYPE_ITEM) {
            //inflate your layout and pass it to view holder
            return new ViewHeader(mHeaderViews.get(viewType));
        }
        ...
    }
    @Override
    public void onBindViewHolder(RecyclerView.ViewHolder holder, int basePosition1) {
        if (holder instanceof ViewHeader) {
            return;
        }
        int basePosition = basePosition1 -  mHeaderViews.size();
        ...
    }
}

No, they are not 0 by default. The simplest way to ensure that all values or defaulted to 0 is to define a constructor

Snapshot() : x(0), y(0) {
}

This ensures that all uses of Snapshot will have initialized values.

To read the values from application.properties we need to just annotate our main class with @SpringBootApplication and the class where you are reading with @Component or variety of it. Below is the sample where I have read the values from application.properties and it is working fine when web service is invoked. If you deploy the same code as is and try to access from http://localhost:8080/hello you will get the value you have stored in application.properties for the key message.

package com.example;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@SpringBootApplication
@RestController
public class DemoApplication {

    @Value("${message}")
    private String message;

    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }

    @RequestMapping("/hello")
    String home() {
        return message;
    }

}

The global scope in React Native is variable global. Such as global.foo = foo, then you can use global.foo anywhere.

But do not abuse it! In my opinion, global scope may used to store the global config or something like that. Share variables between different views, as your description, you can choose many other solutions(use redux,flux or store them in a higher component), global scope is not a good choice.

A good practice to define global variable is to use a js file. For example global.js

global.foo = foo;
global.bar = bar;

Then, to make sure it is executed when project initialized. For example, import the file in index.js:

import './global.js'
// other code

Now, you can use the global variable anywhere, and don't need to import global.js in each file. Try not to modify them!

Method #1:

To achieve a completely transparent status bar, you have to use statusBarColor, which is only available on API 21 and above. windowTranslucentStatus is available on API 19 and above, but it adds a tinted background for the status bar. However, setting windowTranslucentStatus does achieve one thing that changing statusBarColor to transparent does not: it sets the SYSTEM_UI_FLAG_LAYOUT_STABLE and SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN flags. The easiest way to get the same effect is to manually set these flags, which effectively disables the insets imposed by the Android layout system and leaves you to fend for yourself.

You call this line in your onCreate method:

getWindow().getDecorView().setSystemUiVisibility(
    View.SYSTEM_UI_FLAG_LAYOUT_STABLE
    | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);

Be sure to also set the transparency in /res/values-v21/styles.xml:

<item name="android:statusBarColor">@android:color/transparent</item>

Or set the transparency programmatically:

getWindow().setStatusBarColor(Color.TRANSPARENT);

The good side to this approach is that the same layouts and designs can also be used on API 19 by trading out the transparent status bar for the tinted translucent status bar.

<item name="android:windowTranslucentStatus">true</item>

Method #2:

If you only need to paint a background image under your status bar, instead of positioning a view behind it, this can be done by simply setting the background of your activity's theme to the desired image and setting the status bar transparency as shown in method #1. This was the method I used to create the screenshots for the Android Police article from a few months ago.

Method #3:

If you've got to ignore the standard system insets for some layouts while keeping them working in others, the only viable way to do it is to work with the often linked ScrimInsetsFrameLayout class. Of course, some of the things done in that class aren't necessary for all scenarios. For example, if you don't plan to use the synthetic status bar overlay, simply comment out everything in the init() method and don't bother adding anything to the attrs.xml file. I've seen this approach work, but I think you'll find that it brings some other implications that may be a lot of work to get around.

I also saw that you're opposed to wrapping multiple layouts. In the case of wrapping one layout inside of another, where both have match_parent for height and width, the performance implications are too trivial to worry about. Regardless, you can avoid that situation entirely by changing the class it extends from FrameLayout to any other type of Layout class you like. It will work just fine.

Go to the Eclipse base folder ? open eclipse.ini ? you will find the below line at line no 4:

plugins/org.eclipse.equinox.launcher.win32.win32.x86_64_1.1.200.v20150204-1316 plugins/org.eclipse.equinox.launcher.win32.win32.x86_1.1.200.v20120913-144807

As you can see, line 1 is of 64-bit Eclipse. It contains x86_64 and line 2 is of 32-bit Eclipse. It contains x_86.

For 32-bit Eclipse only x86 will be present and for 64-bit Eclipse x86_64 will be present.

The STAThreadAttribute marks a thread to use the Single-Threaded COM Apartment if COM is needed. By default, .NET won't initialize COM at all. It's only when COM is needed, like when a COM object or COM Control is created or when drag 'n' drop is needed, that COM is initialized. When that happens, .NET calls the underlying CoInitializeEx function, which takes a flag indicating whether to join the thread to a multi-threaded or single-threaded apartment.

Read more info here (Archived, June 2009)

and

Why is STAThread required?

Add this function to your helper file and simply call.

function getRawQuery($sql){
        $query = str_replace(array('?'), array('\'%s\''), $sql->toSql());
        $query = vsprintf($query, $sql->getBindings());     
        return $query;
}

Output: "select * from user where status = '1' order by id desc limit 25 offset 0"

If you would like to run it locally, use this -

mvn spring-boot:run -Drun.jvmArguments='-Dserver.port=8085'

As of Spring Boot 2.0, here's the command that works (clues were here):

mvn spring-boot:run -Dspring-boot.run.arguments=--server.port=8085

Swift 4.1 introduces new -Osize optimization mode.

In Swift 4.1 the compiler now supports a new optimization mode which enables dedicated optimizations to reduce code size.

The Swift compiler comes with powerful optimizations. When compiling with -O the compiler tries to transform the code so that it executes with maximum performance. However, this improvement in runtime performance can sometimes come with a tradeoff of increased code size. With the new -Osize optimization mode the user has the choice to compile for minimal code size rather than for maximum speed.

To enable the size optimization mode on the command line, use -Osize instead of -O.

If you were wondering, this is actually for an ASCOM Telescope Driver.

First, I took advice from above and created some platforma variables in a seperate file, you can see those scattered through the XML.

The if-then-else part near the top deals with x86 vs x64 compatibility. My assembly targets 'Any CPU' so on an x64 system, I need to register it twice, once in the 64-bit registry and once in the 32-bit Wow6432Node areas. The if-then-else sets me up for this, the values are used in a foreach loop later on. This way, I only have to author the registry keys once (DRY principle).

The file element specifies the actual assembly dll being installed and registered:

<File Id="filDriverAssembly" Source="$(var.TiGra.Astronomy.AWRDriveSystem.TargetPath)" KeyPath="yes" Vital="yes" Assembly=".net" AssemblyApplication="filDriverAssembly"  />

Nothing revolutionary, but notice the Assembly=".net" - this attribute alone would cause the assembly to be put into the GAC, which is NOT what I wanted. Using the AssemblyApplication attribute to point back to itself is simply a way of stopping Wix putting the file into the GAC. Now that Wix knows it's a .net assembly, though, it lets me use certain binder variables within my XML, such as the !(bind.assemblyFullname.filDriverAssembly) to get the assembly full name.

You are probably looking for the DATEDIFF function.

DATEDIFF ( datepart , startdate , enddate )

Where you code might look like this:

DATEDIFF ( hh , startdate , enddate )

Found a working answer in a separate thread:

There's no one event that will always work, and monkey patching the pushState event is pretty hit or miss for most major SPAs.

So smart polling is what's worked best for me. You can add as many event types as you like, but these seem to be doing a really good job for me.

Written for TS, but easily modifiable:

const locationChangeEventType = "MY_APP-location-change";

// called on creation and every url change
export function observeUrlChanges(cb: (loc: Location) => any) {
  assertLocationChangeObserver();
  window.addEventListener(locationChangeEventType, () => cb(window.location));
  cb(window.location);
}

function assertLocationChangeObserver() {
  const state = window as any as { MY_APP_locationWatchSetup: any };
  if (state.MY_APP_locationWatchSetup) { return; }
  state.MY_APP_locationWatchSetup = true;

  let lastHref = location.href;

  ["popstate", "click", "keydown", "keyup", "touchstart", "touchend"].forEach((eventType) => {
    window.addEventListener(eventType, () => {
      requestAnimationFrame(() => {
        const currentHref = location.href;
        if (currentHref !== lastHref) {
          lastHref = currentHref;
          window.dispatchEvent(new Event(locationChangeEventType));
        }
      })
    })
  });
}

Usage

observeUrlChanges((loc) => {
  console.log(loc.href)
})

This code works for me:

Sub test()
    Dim myRange As Range
    Dim NumRows As Integer

    Set myRange = Range("A:A")
    NumRows = Application.WorksheetFunction.CountA(myRange)

    MsgBox NumRows
End Sub

Google, as of now, cannot open w/out saving. As a workaround, I use IE Tab from the Chrome Store. It is an extension that runs IE - which does allow opening w/ out saving- inside of the Chrome browser application.

Not the best solution, but it's an effective "patch" for now.

I had a need to add a guid primary key column in an existing table and populate it with unique GUID's and this update query with inner select worked for me:

UPDATE sri_issued_quiz SET quiz_id=(SELECT uuid());

So simple :-)

Here's a link to my tutorial, which walks you through :

• creating a JSON WCF Web Service from scratch (and the problems you'll want to avoid)
• adapting it to read/write SQL Server data
• getting an iOS 6 app to use the JSON servies.
• using the JSON web services with JavaScript

An Ad-hoc query is one created to provide a specific recordset from any or multiple merged tables available on the DB server. These queries usually serve a single-use purpose, and may not be necessary to incorporate into any stored procedure to run again in the future.

Ad-hoc scenario: You receive a request for a specific subset of data with a unique set of variables. If there is no pre-written query that can provide the necessary results, you must write an Ad-hoc query to generate the recordset results.

Beyond a single use Ad-hoc query are stored procedures; i.e. queries which are stored within the DB interface tool. These stored procedures can then be executed in sequence within a module or macro to accomplish a predefined task either on demand, on a schedule, or triggered by another event.

Stored Procedure scenario: Every month you need to generate a report from the same set of tables and with the same variables (these variables may be specific predefined values, computed values such as “end of current month”, or a user’s input values). You would created the procedure as an ad-hoc query the first time. After testing the results to ensure accuracy, you may chose to deploy this query. You would then store the query or series of queries in a module or macro to run again as needed.

Checking for installed php modules and packages

In addition to running

php -m

to get the list of installed php modules, you will probably find it helpful to get the list of the currently installed php packages in Ubuntu:

sudo dpkg --get-selections | grep -v deinstall | grep php

This is helpful since Ubuntu makes php modules available via packages.

You can then install the needed modules by selecting from the available Ubuntu php packages, which you can view by running:

sudo apt-cache search php | grep "^php5-"

Or, for Ubuntu 16.04 and higher:

sudo apt-cache search php | grep "^php7"

As you have mentioned, there is plenty of information available on the actual installation of the packages that you might require, so I won't go into detail about that here.

Related: Enabling / disabling installed php modules

It is possible that an installed module has been disabled. In that case, it won't show up when running php -m, but it will show up in the list of installed Ubuntu packages.

Modules can be enabled/disabled via the php5enmod tool (phpenmod on later distros) which is part of the php-common package.

Ubuntu 12.04:

Enabled modules are symlinked in /etc/php5/conf.d

Ubuntu 12.04: (with PHP 5.4+)

To enable an installed module:

php5enmod <modulename>

To disable an installed module:

php5dismod <modulename>

Ubuntu 16.04 (php7) and higher:

To enable an installed module:

phpenmod <modulename>

To disable an installed module:

phpdismod <modulename>

Reload Apache

Remember to reload Apache2 after enabling/disabling:

service apache2 reload

Try This :

document.getElementById(<element_ID>).readOnly=true;

I used the above logic but modified it slightly. My input is of format : "apple:100|pinapple:200|orange:300" stored in a variable @updtAdvanceKeyVal

Here is the function block :

set @res = "";

set @i = 1;
set @updtAdvanceKeyVal = updtAdvanceKeyVal;

REPEAT


 -- set r =  replace(SUBSTRING(SUBSTRING_INDEX(@updtAdvanceKeyVal, "|", @i),
 --  LENGTH(SUBSTRING_INDEX(@updtAdvanceKeyVal, "|", @i -1)) + 1),"|","");

-- wrapping the function in "replace" function as above causes to cut off a character from
 -- the 2nd splitted value if the value is more than 3 characters. Writing it in 2 lines causes no such problem and the output is as expected
-- sample output by executing the above function :
-- orange:100
-- pi apple:200    !!!!!!!!strange output!!!!!!!!
-- tomato:500

      set @r =  SUBSTRING(SUBSTRING_INDEX(@updtAdvanceKeyVal, "|", @i),
                  LENGTH(SUBSTRING_INDEX(@updtAdvanceKeyVal, "|", @i -1)) + 1);

      set @r = replace(@r,"|","");

      if @r <> "" then

              set @key = SUBSTRING_INDEX(@r, ":",1);
              set @val = SUBSTRING_INDEX(@r, ":",-1);

              select @key, @val;
      end if;

      set @i = @i + 1;

     until @r = ""
END REPEAT;

How this works?

Example: http://jsfiddle.net/953Yj/

<div class="center">
    Lorem ipsum
</div>

.center{
    position:absolute;
    height: X px;
    width: Y px;
    left:50%;
    top:50%;
    margin-top:- X/2 px;
    margin-left:- Y/2 px;
}

• X would your your height.
• Y would be your width.

To position the div vertically and horizontally, divide X and Y by 2.

With Jeffrey Fox's interpretation about no-cache, i've tested under chrome 52.0.2743.116 m, the result shows that no-cache has the same behavior as must-revalidate, they all will NOT use local cache when server is unreachable, and, they all will use cache while tap browser's Back/Forward button when server is unreachable. As above, i think max-age=0, must-revalidate is identical to no-cache, at least in implementation.

In a method of your Form or Control, you have 3 choices:

this.Invalidate();  // request a delayed Repaint by the normal MessageLoop system    
this.Update();      // forces Repaint of invalidated area 
this.Refresh();     // Combines Invalidate() and Update()

Normally, you would just call Invalidate() and let the system combine that with other Screen updates. If you're in a hurry you should call Refresh() but then you run the risk that it will be repainted several times consecutively because of other controls (especially the Parent) Invalidating.

The normal way Windows (Win32 and WinForms.Net) handles this is to wait for the MessageQueue to run empty and then process all invalidated screen areas. That is efficient because when something changes that usually cascades into other things (controls) changing as well.

The most common scenario for Update() is when you change a property (say, label1.Text, which will invalidate the Label) in a for-loop and that loop is temporarily blocking the Message-Loop. Whenever you use it, you should ask yourself if you shouldn't be using a Thread instead. But the answer is't always Yes.

To keep the promise chain going, you can't use setTimeout() the way you did because you aren't returning a promise from the .then() handler - you're returning it from the setTimeout() callback which does you no good.

Instead, you can make a simple little delay function like this:

function delay(t, v) {
   return new Promise(function(resolve) { 
       setTimeout(resolve.bind(null, v), t)
   });
}

And, then use it like this:

getLinks('links.txt').then(function(links){
    let all_links = (JSON.parse(links));
    globalObj=all_links;

    return getLinks(globalObj["one"]+".txt");

}).then(function(topic){
    writeToBody(topic);
    // return a promise here that will be chained to prior promise
    return delay(1000).then(function() {
        return getLinks(globalObj["two"]+".txt");
    });
});

Here you're returning a promise from the .then() handler and thus it is chained appropriately.

You can also add a delay method to the Promise object and then directly use a .delay(x) method on your promises like this:

function delay(t, v) {_x000D_
   return new Promise(function(resolve) { _x000D_
       setTimeout(resolve.bind(null, v), t)_x000D_
   });_x000D_
}_x000D_
_x000D_
Promise.prototype.delay = function(t) {_x000D_
    return this.then(function(v) {_x000D_
        return delay(t, v);_x000D_
    });_x000D_
}_x000D_
_x000D_
_x000D_
Promise.resolve("hello").delay(500).then(function(v) {_x000D_
    console.log(v);_x000D_
});

Or, use the Bluebird promise library which already has the .delay() method built-in.

Single line works just fine:

<a href="http://example.com/"
 onclick="return confirm('Please click on OK to continue.');">click me</a>

Adding another line with a different link on the same page works fine too:

<a href="http://stackoverflow.com/"
 onclick="return confirm('Click on another OK to continue.');">another link</a>

1. Drop the primary key first: (The primary key is your responsibility)

   ALTER TABLE Persons DROP PRIMARY KEY ;
   

2. Then make all insertions:

3. Add new primary key just like before dropping:

   ALTER TABLE Persons ADD PRIMARY KEY (P_Id);
   

Take a look at the PDOStatement.fetchAll method. You could also use fetch in an iterator pattern.

Code sample for fetchAll, from the PHP documentation:

<?php
$sth = $dbh->prepare("SELECT name, colour FROM fruit");
$sth->execute();

/* Fetch all of the remaining rows in the result set */
print("Fetch all of the remaining rows in the result set:\n");
$result = $sth->fetchAll(\PDO::FETCH_ASSOC);
print_r($result);

Results:

Array
(
    [0] => Array
        (
            [NAME] => pear
            [COLOUR] => green
        )

    [1] => Array
        (
            [NAME] => watermelon
            [COLOUR] => pink
        )
)

For people who use Bootstrap, textarea.form-control can lead to textarea sizing issues as well. Chrome and Firefox appear to use different heights with the following Bootstrap CSS:

textarea.form-conrtol{
    height:auto;
}

For a time difference, note that the calendar starts at 01.01.1970, 01:00, not at 00:00. If you're using java.util.Date and java.text.SimpleDateFormat, you will have to compensate for 1 hour:

long start = System.currentTimeMillis();
long end = start + (1*3600 + 23*60 + 45) * 1000 + 678; // 1 h 23 min 45.678 s
Date timeDiff = new Date(end - start - 3600000); // compensate for 1h in millis
SimpleDateFormat timeFormat = new SimpleDateFormat("H:mm:ss.SSS");
System.out.println("Duration: " + timeFormat.format(timeDiff));

This will print:

Duration: 1:23:45.678

This was working fine for me, hope it helps others too. to get this i have struggled more days. :(

We build our project using ant, so we can use the schemavalidate task to check our config files:

<schemavalidate> 
    <fileset dir="${configdir}" includes="**/*.xml" />
</schemavalidate>

Now naughty config files will fail our build!

Split the text into lines, and draw each separately:

function fillTextMultiLine(ctx, text, x, y) {
  var lineHeight = ctx.measureText("M").width * 1.2;
  var lines = text.split("\n");
  for (var i = 0; i < lines.length; ++i) {
    ctx.fillText(lines[i], x, y);
    y += lineHeight;
  }
}

• first you cannot extend AsyncTask without override doInBackground

• second try to create AlterDailog from the builder then call show().

I wrote a tutorial about this a while ago.

The most important point is the "Site URL":

Site URL: http://localhost/app_name/

Where the folder structure is something like:

app_name
¦   index.php
¦
+---canvas
¦   ¦   index.php
¦   ¦
¦   +---css
¦           main.css
¦           reset.css
¦
+---src
        facebook.php
        fb_ca_chain_bundle.crt

EDIT:
Kavya: how does the FB server recognize my localhost even without an IP or port??

I don't think this has anything to do with Facebook, I guess since the iframe src parameter is loaded from client-side it'll treat your local URL as if you put it directly on your browser.

For example have a file on your online server with content (e.g. online.php):

<iframe src="http://localhost/test.php" width="100%" height="100%">
    <p>Not supported!</p>
</iframe>

And on your localhost root directory, have the file test.php:

<?php echo "Hello from Localhost!"; ?>

Now visit http://your_domain.com/online.php you will see your localhost file's content!

This is why realtime subscriptions and deauthorize callbacks (just to mention) won't work with localhost URLs! because Facebook will ping (send http requests) to these URLs but obviously Facebook server won't translate those URLs to yours!

You can also do it like this (string to list conversion here, then conversion to a dictionary)

    string_list = """
    Hello World
    Goodbye Night
    Great Day
    Final Sunset
    """.split()

    string_list = dict(zip(string_list[::2],string_list[1::2]))

    print string_list

while Alexey Kukanov's answer may be more efficient, you can also iterate through a queue in a very natural manner, by popping each element from the front of the queue, then pushing it to the back:

#include <iostream>
#include <queue>

using namespace std;

int main() {
    //populate queue
    queue<int> q;
    for (int i = 0; i < 10; ++i) q.push(i);

    // iterate through queue
    for (size_t i = 0; i < q.size(); ++i) {
        int elem = std::move(q.front());
        q.pop();
        elem *= elem;
        q.push(std::move(elem));
    }

    //print queue
    while (!q.empty()) {
        cout << q.front() << ' ';
        q.pop();
    }
}

output:

0 1 4 9 16 25 36 49 64 81 

Sometimes we need a code block where we need to perform some operation right after setState where we are sure the state is being updated. That is where setState callback comes into play

For example, there was a scenario where I needed to enable a modal for 2 customers out of 20 customers, for the customers where we enabled it, there was a set of time taking API calls, so it looked like this

async componentDidMount() {
  const appConfig = getCustomerConfig();
  this.setState({enableModal: appConfig?.enableFeatures?.paymentModal }, async 
   ()=>{
     if(this.state.enableModal){
       //make some API call for data needed in poput
     }
  });
}

enableModal boolean was required in UI blocks in the render function as well, that's why I did setState here, otherwise, could've just checked condition once and either called API set or not.

I had this same problem and I was able to fix it. afk5min was right, the problem is the branch that you pulled code from has since changed on the remote repository. Per the standard git practices(http://git-scm.com/book/en/Git-Basics-Working-with-Remotes), you need to (now) merge those changes at the remote repository into your local changes before you can commit. This makes sense, this forces you to take other's changes and merge them into your code, ensuring that your code continues to function with the other changes in place.

Anyway, on to the steps.

1. Configure the 'fetch' to fetch the branch you originally pulled from.

2. Fetch the remote branch.

3. Merge that remote branch onto your local branch.

4. Commit the (merge) change in your local repo.

5. Push the change to the remote repo.

In detail...

1. In eclipse, open the view 'Git Repositories'.

2. Ensure you see your local repository and can see the remote repository as a subfolder. In my version, it's called Remotes, and then I can see the remote project within that.

3. Look for the green arrow pointing to the left, this is the 'fetch' arrow. Right click and select 'Configure Fetch'.

4. You should see the URI, ensure that it points to the remote repository.

5. Look in the ref mappings section of the pop-up. Mine was empty. This will indicate which remote references you want to fetch. Click 'Add'.

6. Type in the branch name you need to fetch from the remote repository. Mine was 'master' (btw, a dropdown here would be great!!, for now, you have to type it). Continue through the pop-up, eventually clicking 'Finish'.

7. Click 'Save and Fetch'. This will fetch that remote reference.

8. Look in the 'Branches' folder of your local repository. You should now see that remote branch in the remote folder. Again, I see 'master'.

9. Right-Click on the local branch in the 'Local' folder of 'Branches', which is named 'master'. Select 'Merge', and then select the remote branch, which is named 'origin/master'.

10. Process through the merge.

11. Commit any changes to your local repository.

12. Push your changes to the remote repository.

13. Go have a tasty beverage, congratulating yourself. Take the rest of the day off.

LinkedHashMap is precisely what you're looking for.

It is exactly like HashMap, except that when you iterate over it, it presents the items in the insertion order.

The vast majority of current android 2.1+ phone screens are 480x800 (or in the case of motodroid oddities, 480x854)

However, this doesn't mean this should be your only concern. You need to make it looking good on tablets, and smaller or 4:3 ratio smaller screens.

RelativeLayout is your friend!

This is very simple you are trying to convert an integer to a list object !!! of course it will fail and it should ...

To demonstrate/prove this to you by using the example you provided ...just use type function for each case as below and the results will speak for itself !

<class 'range'>
>>> 
>>> type(cow[0])
<class 'int'>
>>> 
>>> type(0)
<class 'int'>
>>> 
>>> >>> list(0)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'int' object is not iterable

The code you have at the moment seems to be all right. Check what the checkboxes array contains using this. Add this code on the top of your php script and see whether the checkboxes are being passed to your script.

echo '<pre>'.print_r($_POST['myCheckboxes'], true).'</pre>';
exit;

Close nodejs app running in another shell. Restart the terminal and run the program again.

Another server might be also using the same port that you have used for nodejs. Kill the process that is using nodejs port and run the app.

8000/tcp:            16708

Here PID is 16708 Now kill the process using the kill [PID] command

$ kill 16708

You can use display:inline-block instead of float and vertical-align:middle with this CSS:

.col-lg-4, .col-lg-8 {
    float:none;
    display:inline-block;
    vertical-align:middle;
    margin-right:-4px;
}

The issue HttpServletRequest.login does not set authentication state in session has been fixed in 3.0.1. Update glassfish to the latest version and you're done.

Updating is quite straightforward:

Disk space is not the issue... but memory and performance will be. Double the page reads, double index size, strange LIKE and = constant behaviour etc

Do you need to store Chinese etc script? Yes or no...

And from MS BOL "Storage and Performance Effects of Unicode"

Edit:

Recent SO question highlighting how bad nvarchar performance can be...

SQL Server uses high CPU when searching inside nvarchar strings

Here is a more easy solution. just remove the "navbar-nav" class and add "nav-justified".

As mentioned in the comments height:100% relies on the height of the parent container being explicitly defined. One way to achieve what you want is to use absolute/relative positioning, and specifying the left/right/top/bottom properties to "stretch" the content out to fill the available space. I have implemented what I gather you want to achieve in jsfiddle. Try resizing the Result window and you will see the content resizes automatically.

The limitation of this approach in your case is that you have to specify an explicit margin-top on the parent container to offset its contents down to make room for the header content. You can make it dynamic if you throw in javascript though.

I had the same problem and I fixed it by using the

1. new context menu "Make Public".
2. Go to https://console.aws.amazon.com/s3/home,
3. select the bucket and then for each Folder or File (or multiple selects) right click and
4. "make public"

As others have said, BeautifulSoup doesn't have xpath support. There are probably a number of ways to get something from an xpath, including using Selenium. However, here's a solution that works in either Python 2 or 3:

from lxml import html
import requests

page = requests.get('http://econpy.pythonanywhere.com/ex/001.html')
tree = html.fromstring(page.content)
#This will create a list of buyers:
buyers = tree.xpath('//div[@title="buyer-name"]/text()')
#This will create a list of prices
prices = tree.xpath('//span[@class="item-price"]/text()')

print('Buyers: ', buyers)
print('Prices: ', prices)

I used this as a reference.

If you are starting new and its a java application then Spring ROO looks very interesting too!

Hope that helps.

All params will be stored in jsonObject.

The byte array contains characters in a special encoding (that you should know). The way to convert it to a String is:

String decoded = new String(bytes, "UTF-8");  // example for one encoding type

By The Way - the raw bytes appear may appear as negative decimals just because the java datatype byte is signed, it covers the range from -128 to 127.

-109 = 0x93: Control Code "Set Transmit State"

The value (-109) is a non-printable control character in UNICODE. So UTF-8 is not the correct encoding for that character stream.

0x93 in "Windows-1252" is the "smart quote" that you're looking for, so the Java name of that encoding is "Cp1252". The next line provides a test code:

System.out.println(new String(new byte[]{-109}, "Cp1252")); 

You are missing zlib.h header file, on Linux install it via:

sudo apt-get install libz-dev

As a matter of fact, the module presents as zlib1g-dev in the apt repo, so this is the up-to-date call (Feb 2019):

sudo apt install zlib1g-dev

On Fedora: sudo dnf install zlib-devel (in older versions: sudo dnf install libz-devel).

This will provide the development support files for a library implementing the deflate compression method found in gzip and PKZIP.

If you've already zlib library, make sure you're compiling your code sources with -lz. See: How to fix undefined references to inflate/deflate functions?.

Unfortunately, none of those solutions worked for me. Perhaps, due to the difference in the initialization of our tables, we have different results. It might be possible, that one of those solutions would work for someone. Anyways, wanted to share my solution, just in case someone is still troubled with this issue. It is a bit hackish, though, but it works for me, since I don't change the width of the table later.

After I load the page and click on the header, so that it expands and shows normally, I inspect the table header and record the width of the .dataTables_scrollHeadInner div. In my case it is 715px, for example. Then add that width to css:

.dataTables_scrollHeadInner
{
  width: 715px !important;
}

Just a variation on the answers above.

I tried the straight up node command above without success, but the suggestion from this Angular CLI issue worked for me - you create a Node script in your package.json file to increase the memory available to Node when you run your production build.

So if you want to increase the memory available to Node to 4gb (max-old-space-size=4096), your Node command would be node --max-old-space-size=4096 ./node_modules/@angular/cli/bin/ng build --prod. (increase or decrease the amount of memory depending on your needs as well - 4gb worked for me, but you may need more or less). You would then add it to your package.json 'scripts' section like this:

"prod": "node --max-old-space-size=4096 ./node_modules/@angular/cli/bin/ng build --prod"

It would be contained in the scripts object along with the other scripts available - e.g.:

"scripts": {
    "ng": "ng",
    "start": "ng serve",
    "build": "ng build",
    "test": "ng test",
    "lint": "ng lint",
    "e2e": "ng e2e",
    "prod": "node --max-old-space-size=4096./node_modules/@angular/cli/bin/ng build --prod"
}

And you run it by calling npm run prod (you may need to run sudo npm run prod if you're on a Mac or Linux).

Note there may be an underlying issue which is causing Node to need more memory - this doesn't address that if that's the case - but it at least gives Node the memory it needs to perform the build.

I'm assuming you figured this out already but:

Technical Reference for Log Files in Configuration Manager

That's a list of client-side logs and what they do. They are located in Windows\CCM\Logs

AppEnforce.log will show you the actual command-line executed and the resulting exit code for each Deployment Type (only for the new style ConfigMgr Applications)

This is my go-to for troubleshooting apps. Haven't really found any other logs that are exceedingly useful.

if you testing some javascript requests for ionic2 or angularjs 2 , in your chrome on pc or mac , then be sure that you install CORS plugin for chrome browser to allow cross origin .

mayba get requests will work without needing that , but post and puts and delete will need you to install cors plugin for testing to go without problems , that definitley not cool , but i do not know how people do it without CORS plugin .

and also be sure the json response is not returning 400 by some json status

The for attribute shows that this label stands for related input field, or check box or radio button or any other data entering field associated with it. for example

<li>
    <label>{translate:blindcopy}</label>
    <a class="" href="#" title="{translate:savetemplate}" onclick="" ><i class="fa fa-list" class="button" ></i></a> &nbsp 
            <input type="text" id="BlindCopy" name="BlindCopy" class="splitblindcopy" />

</li>

You can have only one default export which you declare like:

export default App; or export default class App extends React.Component {...

and later do import App from './App'

If you want to export something more you can use named exports which you declare without default keyword like:

export {
  About,
  Contact,
}

or:

export About;
export Contact;

or:

export const About = class About extends React.Component {....
export const Contact = () => (<div> ... </div>);

and later you import them like:

import App, { About, Contact } from './App';

EDIT:

There is a mistake in the tutorial as it is not possible to make 3 default exports in the same main.js file. Other than that why export anything if it is no used outside the file?. Correct main.js :

import React from 'react';
import ReactDOM from 'react-dom';
import { Router, Route, Link, browserHistory, IndexRoute  } from 'react-router'

class App extends React.Component {
...
}

class Home extends React.Component {
...
}


class About extends React.Component {
...
}


class Contact extends React.Component {
...
}


ReactDOM.render((
   <Router history = {browserHistory}>
      <Route path = "/" component = {App}>
         <IndexRoute component = {Home} />
         <Route path = "home" component = {Home} />
         <Route path = "about" component = {About} />
         <Route path = "contact" component = {Contact} />
      </Route>
   </Router>

), document.getElementById('app'))

EDIT2:

another thing is that this tutorial is based on react-router-V3 which has different api than v4.

try this regex (allowing Alphabets, Dots, Spaces):

"^[A-Za-z\s]{1,}[\.]{0,1}[A-Za-z\s]{0,}$" //regular
"^\pL+[\pL\pZ\pP]{0,}$" //unicode

This will also ensure DOT never comes at the start of the name.

Just add the line below to the <TextInput>

secureTextEntry={true}

sum([1 for elem in <yourlist> if elem==<your_value>])

This will return the amount of occurences of your_value

You can access characters in strings in the same way as you would access an array index, e.g.

$length = strlen($string);
$thisWordCodeVerdeeld = array();
for ($i=0; $i<$length; $i++) {
    $thisWordCodeVerdeeld[$i] = $string[$i];
}

You could also do:

$thisWordCodeVerdeeld = str_split($string);

However you might find it is easier to validate the string as a whole string, e.g. using regular expressions.

Probably the path you supplied was not correct. Check that.

I would recomment the article Howto: (Almost) Everything In Active Directory via C# which really helped me in the past in dealing with AD.

Anups answer in swift. Can be reused from any class.

In swift file

extension NSMutableAttributedString {

    func setColorForStr(textToFind: String, color: UIColor) {

        let range = self.mutableString.rangeOfString(textToFind, options:NSStringCompareOptions.CaseInsensitiveSearch);
        if range.location != NSNotFound {
            self.addAttribute(NSForegroundColorAttributeName, value: color, range: range);
        }

I've successfully used pdftk to remove pages I didn't want/need in pdfs. You can download the program here

You might try something like the following. Taken from here under examples

Remove 'page 13' from in1.pdf to create out1.pdf pdftk in.pdf cat 1-12 14-end output out1.pdf

or:

pdftk A=in1.pdf cat A1-12 A14-end output out1.pdf

I fixed this issue by adding following code in my file.

@Component
@Scope(value = "session",  proxyMode = ScopedProxyMode.TARGET_CLASS)

XML configuration -

<listener>
        <listener-class>
            org.springframework.web.context.request.RequestContextListener 
        </listener-class>
</listener>

Above we can do using Java configuration -

@Configuration
@WebListener
public class MyRequestContextListener extends RequestContextListener {
}

How to add a RequestContextListener with no-xml configuration?

I am using spring version 5.1.4.RELEASE and no need to add below changes in pom.

<dependency>
    <groupId>cglib</groupId>
    <artifactId>cglib</artifactId>
    <version>3.2.10</version>

After experimenting for a few hours I figured it out.

<% if @user.errors.full_messages.any? %>
  <% @user.errors.full_messages.each do |error_message| %>
    <%= error_message if @user.errors.full_messages.first == error_message %> <br />
  <% end %>
<% end %>

Even better:

<%= @user.errors.full_messages.first if @user.errors.any? %>

Note: Due to reputation I cannot comment on bdeem's post. I'm posting my findings as an answer instead.

Following bdeem's post, I did the following (in order):

1. I modified the [project].csproj file. Added the <Content Include="" /> tags to the ItemGroup for the different config files and made them dependent on the original config file.

Note: Using <None Include="" /> will not work with the transformation.

<!-- App.config Settings -->
<!-- Create App.($Configuration).config files here. -->
<Content Include="App.config" />
<Content Include="App.Debug.config">
  <DependentUpon>App.config</DependentUpon>
</Content>
<Content Include="App.Release.config">
  <DependentUpon>App.config</DependentUpon>
</Content>

2. At the bottom of the [project].csproj file (before the closing </Project> tag), I imported the ${MSBuildToolsPath\Microsoft.CSharp.targets file, added the UsingTask to transform the XML and added the Target to copy the transformed App.config file to the output location.

Note: The Target will also overwrite the App.Config in the local directory to see immediate changes working locally. The Target also uses the Name="Afterbuild" property to ensure the config files can be transformed after the executables are generated. For reasons I do not understand, when using WCF endpoints, if I use Name="CoreCompile", I will get warnings about the service attributes. Name="Afterbuild" resolved this.

  <!-- Task to transform the App.config using the App.($Configuration).config file. -->
  <UsingTask TaskName="TransformXml" AssemblyFile="$(MSBuildExtensionsPath)\Microsoft\VisualStudio\v$(VisualStudioVersion)\Web\Microsoft.Web.Publishing.Tasks.dll" />

  <!-- Only compile the App.config if the App.($Configuration).config file exists. -->
  <!-- Make sure to use the AfterBuild name instead of CoreCompile to avoid first time build errors and WCF endpoint errors. -->
  <Target Name="AfterBuild" Condition="exists('App.$(Configuration).config')">
    <!-- Generate transformed App.config in the intermediate output directory -->    
    <TransformXml Source="App.config" Destination="$(IntermediateOutputPath)$(TargetFileName).config" Transform="App.$(Configuration).config" />
    
    <!-- Modify the original App.config file with the transformed version. -->
    <TransformXml Source="App.config" Destination="App.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>
</Project>

3. Went back into Visual Studio and reloaded the modified files.

4. Manually added the App.*.config files to the project. This allowed them to group under the original App.config file.

Note: Make sure the App.*.config files have the proper XML structure.

<?xml version="1.0" encoding="utf-8"?>

<!-- For more information on using web.config transformation visit https://go.microsoft.com/fwlink/?LinkId=125889 -->

<configuration xmlns:xdt="http://schemas.microsoft.com/XML-Document-Transform">
  <connectionStrings>
    <add name="myConn" connectionString=""; Initial Catalog=; User ID=; Password=;" xdt:Transform="SetAttributes" xdt:Locator="Match(name)" />
  </connectionStrings>
</configuration>

5. Re-built the project.

The following series of steps might be helpful:

1. Open Windows Explorer
2. In the top-left corner, click "Organize"
3. select "Folder and Search Options"
4. Switch to the "View" tab
5. Scroll down and uncheck "Hide file extensions for known file types"
6. Click OK
7. Now find the dll file
8. Right-click on it and select "Rename"
9. Change the extension(what comes after the last .) and change it to .exe

You should use some form of the String#equals(Object) method. However, there is some subtlety in how you should do it:

If you have a string literal then you should use it like this:

"Hello".equals(someString);

This is because the string literal "Hello" can never be null, so you will never run into a NullPointerException.

If you have a string and another object then you should use:

myString.equals(myObject);

You can make sure you are actually getting string equality by doing this. For all you know, myObject could be of a class that always returns true in its equals method!

Start with the object less likely to be null because this:

String foo = null;
String bar = "hello";
foo.equals(bar);

will throw a NullPointerException, but this:

String foo = null;
String bar = "hello";
bar.equals(foo);

will not. String#equals(Object) will correctly handle the case when its parameter is null, so you only need to worry about the object you are dereferencing--the first object.

I got a bad result with git push origin branch1:branch2 command:

In my case, branch2 is deleted and branch1 has been updated with some new changes.

Hence, if you want only the changes push on the branch2 from the branch1, try procedures below:

• On branch1: git add .
• On branch1: git commit -m 'comments'

• On branch1: git push origin branch1

• On branch2: git pull origin branch1

• On branch1: revert to the previous commit.

James' answer is correct, of course, but I should remind you that the whole ASMX thing is, if not obsolete, at least not the current method. I strongly suggest that you look into WCF, if only to avoid learning things you will need to forget.

No, Java doesn't have that amazing feature. But you could create it manually using the observer pattern. Here is an example: Write C# delegate in java

As a simplification to chrfin's response, since Chrome should be on the run path if installed, you could just call:

Process.Start("chrome.exe", "http://www.YourUrl.com");

This seem to work as expected for me, opening a new tab if Chrome is already open.

I use the following function extensively. As pointed out above, using other methods can sometimes give inaccurate results due to used range updates, gaps in the data, or different columns having different row counts.

Example of use:

lastRow=FindRange("Sheet1","A1:A1000")

would return the last occupied row number of the entire range. You can specify any range you want from single columns to random rows, eg FindRange("Sheet1","A100:A150")

Public Function FindRange(inSheet As String, inRange As String) As Long
    Set fr = ThisWorkbook.Sheets(inSheet).Range(inRange).find("*", SearchOrder:=xlByRows, SearchDirection:=xlPrevious)
    If Not fr Is Nothing Then FindRange = fr.row Else FindRange = 0
End Function

Off the top of my head:

float fl = 0.678;
int rounded_f = (int)(fl+0.5f);

In regedit.exe go to:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\InstallDate

It's given as the number of seconds since January 1, 1970. (Note: for Windows 10, this date will be when the last feature update was installed, not the original install date.)

To convert that number into a readable date/time just paste the decimal value in the field "UNIX TimeStamp:" of this Unix Time Conversion online tool.

Gradle is a build system. Build systems are software tools designed to automate the process of program compilation. Build systems come in various forms, and are used for a variety of software build tasks. While their primary goal is to efficiently create executables.

Another related term is Build automation which is the process of automating the creation of a software build and the associated processes including: compiling computer source code into binary code, packaging binary code, and running automated tests.

Few similar build system for other languages are (see complete list here):

1. Apache Ant & Apache Maven - Java
2. sbt (Simple Build Tool) - for Scala (Play framework etc)
3. A-A-P - Python based build tool
4. Rake (Apache Builder) - Ruby
5. Leiningen for Clojure

I've got the same error on a fully updated Windows Vista Family 64bit with a .NET application that I've compiled to 32 bit only - the program is installed in the programx86 folder on 64 bit machines. It fails with this error message even with 2007 access database provider installed, with/wiothout the SP2 of the same installed, IIS installed and app pool set for 32bit app support... yes I've tried every solution everywhere and still no success.

I switched my app to ACE OLE DB.12.0 because JET4.0 was failing on 64bit machines - and it's no better :-/ The most promising thread I've found was this:

http://ellisweb.net/2010/01/connecting-to-excel-and-access-files-using-net-on-a-64-bit-server/

but when you try to install the 64 bit "2010 Office System Driver Beta: Data Connectivity Components" it tells you that you can't install the 64 bit version without uninstalling all 32bit office applications... and installing the 32 bit version of 2010 Office System Driver Beta: Data Connectivity Components doesn't solve the initial problem, even with "Microsoft.ACE.OLEDB.12.0" as provider instead of "Microsoft.ACE.OLEDB.14.0" which that page (and others) recommend.

My next attempt will be to follow this post:

The issue is due to the wrong flavor of OLEDB32.DLL and OLEDB32r.DLL being registered on the server. If the 64 bit versions are registered, they need to be unregistered, and then the 32 bit versions registered instead. To fix this, unregister the versions located in %Program Files%/Common Files/System/OLE DB. Then register the versions at the same path but in the %Program Files (x86)% directory.

Has anyone else had so much trouble with both JET4.0 and OLEDB ACE providers on 64 bit machines? Has anyone found a solution if none of the others work?

[start:stop:step]

So If you want to take only 100 first character, use your_string[0:100] or your_string[:100] If you want to take only the character at even position, use your_string[::2] The "default values" for start is 0, for stop - len of string, and for step - 1. So when you don't provide one of its and put ':', it'll use it default value.

Try using the code after you active the sheet:

Dim J as integer
J = ActiveSheet.UsedRange.SpecialCells(xlCellTypeLastCell).Row

If you use Cells.SpecialCells(xlCellTypeLastCell).Row only, the problem will be that the xlCellTypeLastCell information will not be updated unless one do a "Save file" action. But use UsedRange will always update the information in realtime.

Another way to do this:

1. create another branch
2. checkout the previous commit on that branch using "git checkout"
3. push the new branch.
4. delete the old branch & push the delete (use git push origin --delete <branch_name>)
5. rename the new branch into the old branch
6. push again.

//white background
canvas.drawRGB(255, 255, 255);
//border's properties
paint.setColor(Color.BLACK);

paint.setStyle(Paint.Style.STROKE);         
canvas.drawRect(100, 100, 200, 200, paint);

To test if the POST variable has an element called 'userID' you would be better off using array_key_exists .. which actually tests for the existence of the array key not whether its value has been set .. a subtle and probably only semantic difference, but it does improve readability.

and right now your $uid is being set to a boolean value depending whether $__POST['userID'] is set or not ... If I recall from memory you might want to try ...

$uid = (array_key_exists('userID', $_POST)?$_POST['userID']:'guest';

Then you can use an identifiable 'guest' user and render your code that much more readable :)

Another point re isset() even though it is unlikely to apply in this scenario, it's worth remembering if you don't want to get caught out later ... an array element can be legitimately set to NULL ... i.e. it can exist, but be as yet unpopulated, and this could be a valid, acceptable, and testable condition. but :

a = array('one'=>1, 'two'=>null, 'three'=>3);
isset(a['one']) == true
isset(a['two']) == false

array_key_exists(a['one']) == true
array_key_exists(a['two']) == true

Bw sure you know which function you want to use for which purpose.

Updating lines in place in a file is not supported on most file system (a line in a file is just some data that ends with newline, the next line start just after that).

As I see it you have two options:

1. Have your data generating loops be generators, this way they won't consume a lot of memory - you'll get data for each row "just in time"
2. Use a database (sqlite?) and update the rows there. When you're done - export to CSV

Small example for the first method:

from itertools import islice, izip, count
print list(islice(izip(count(1), count(2), count(3)), 10))

This will print

[(1, 2, 3), (2, 3, 4), (3, 4, 5), (4, 5, 6), (5, 6, 7), (6, 7, 8), (7, 8, 9), (8, 9, 10), (9, 10, 11), (10, 11, 12)]

even though count generate an infinite sequence of numbers

You can try the following:

1. Create a view that simply selects all the columns from the original table but add an extra numeric column that increase in value with each record\row. You may need to make this column a non integer column (e.g a decimal and increment it by 1.00 for each record to use it in the RANK() SQL statement).

2. Also add another column (e.g. 'RecordRank') to contain calculated ranked values for all columns using the RANK() OVER SQL clause to create values for this column - see references below. The RANK statement allows you to partition the records and then order each partition records according to the values in the order by column (use the Column with increasing values from step 1 for your order by). You use the columns with identical data in the partition clause so all those similar duplicates are partitioned or grouped together, and then ordered by the values in the extra column (order by column from step1).

   http://msdn.microsoft.com/en-us/library/ms189461.aspx

3, After successfully creating the above view, just write another view to select only records with 'RecordRank' = 1

This should select only one of each record from the duplicates or partitions.

I think your date data should look like 2013-08-14.

<?php
 $yrdata= strtotime('2013-08-14');
    echo date('M-Y', $yrdata);
 ?>
// Output is Aug-2013

I had a similar problem, maybe that help someone, for example - table with 3 columns

SELECT * FROM DataTable WHERE Data_text = 'test' GROUP BY Data_Name ORDER BY Data_Name ASC

or

SELECT Data_Id, Data_Text, Data_Name FROM DataTable WHERE Data_text = 'test' GROUP BY Data_Name ORDER BY Data_Name ASC

Two ways work for me.

You are exceeding the length of int datatype. You can use UNSIGNED attribute to support that value.

SIGNED INT can support till 2147483647 and with UNSIGNED INT allows double than this. After this you still want to save data than use CHAR or VARCHAR with length 10

You can check if a list is inside of another list with this

var list1 = new List<int> { 1, 2, 3, 4, 6 };
var list2 = new List<int> { 2, 3 };
bool a = list1.Any(c => list2.Contains(c));

Just do this

<button OnClick=" location.href='link.html' ">Visit Page Now</button>

Although, it's been a while since I've touched JavaScript - maybe location.href is outdated? Anyways, that's how I would do it.

Consider a simple shopping cart application that uses a CartContents class to keep track of the items in the shopping cart and an Order class for processing a purchase. The Order needs to determine the total value of the contents in the cart, it might do that like so:

Tightly Coupled Example:

public class CartEntry
{
    public float Price;
    public int Quantity;
}

public class CartContents
{
    public CartEntry[] items;
}

public class Order
{
    private CartContents cart;
    private float salesTax;

    public Order(CartContents cart, float salesTax)
    {
        this.cart = cart;
        this.salesTax = salesTax;
    }

    public float OrderTotal()
    {
        float cartTotal = 0;
        for (int i = 0; i < cart.items.Length; i++)
        {
            cartTotal += cart.items[i].Price * cart.items[i].Quantity;
        }
        cartTotal += cartTotal*salesTax;
        return cartTotal;
    }
}

Notice how the OrderTotal method (and thus the Order class) depends on the implementation details of the CartContents and the CartEntry classes. If we were to try to change this logic to allow for discounts, we'd likely have to change all 3 classes. Also, if we change to using a List collection to keep track of the items we'd have to change the Order class as well.

Now here's a slightly better way to do the same thing:

Less Coupled Example:

public class CartEntry
{
    public float Price;
    public int Quantity;

    public float GetLineItemTotal()
    {
        return Price * Quantity;
    }
}

public class CartContents
{
    public CartEntry[] items;

    public float GetCartItemsTotal()
    {
        float cartTotal = 0;
        foreach (CartEntry item in items)
        {
            cartTotal += item.GetLineItemTotal();
        }
        return cartTotal;
    }
}

public class Order
{
    private CartContents cart;
    private float salesTax;

    public Order(CartContents cart, float salesTax)
    {
        this.cart = cart;
        this.salesTax = salesTax;
    }

    public float OrderTotal()
    {
        return cart.GetCartItemsTotal() * (1.0f + salesTax);
    }
}

The logic that is specific to the implementation of the cart line item or the cart collection or the order is restricted to just that class. So we could change the implementation of any of these classes without having to change the other classes. We could take this decoupling yet further by improving the design, introducing interfaces, etc, but I think you see the point.

curl's -w option and the sub variable url_effective is what you are looking for.

Something like

curl -Ls -o /dev/null -w %{url_effective} http://google.com

More info

-L         Follow redirects
-s         Silent mode. Don't output anything
-o FILE    Write output to <file> instead of stdout
-w FORMAT  What to output after completion

You might want to add -I (that is an uppercase i) as well, which will make the command not download any "body", but it then also uses the HEAD method, which is not what the question included and risk changing what the server does. Sometimes servers don't respond well to HEAD even when they respond fine to GET.

In case you are considering using the numpy module, it makes this task very simple, as requested:

import numpy as np

j = np.array([4, 5, 6, 7, 1, 3, 7, 5])

j2 = np.sort(j[j >= 5])

The code inside of the brackets, j >= 5, produces a list of True or False values, which then serve as indices to select the desired values in j. Finally, we sort with the sort function built into numpy.

Tested result (a numpy array):

array([5, 5, 6, 7, 7])

SELECT to_char(emp_login_date,'DD-MON-YYYY HH24:MI:SS'),A.*

AND
to_date(to_char('22-MAY-2015 17:56:52'),'DD-MON-YYYY HH24:MI:SS') 
ORDER BY emp_login_date

pg_hba.conf entry define login methods by IP addresses. You need to show the relevant portion of pg_hba.conf in order to get proper help.

Change this line:

host    all             all             <my-ip-address>/32        md5

To reflect your local network settings. So, if your IP is 192.168.16.78 (class C) with a mask of 255.255.255.0, then put this:

host    all             all             192.168.16.0/24        md5

Make sure your WINDOWS MACHINE is in that network 192.168.16.0 and try again.

Poor man's profiling, no extensions required. Supports nested profiles and percent of total:

function p_open($flag) {
    global $p_times;
    if (null === $p_times)
        $p_times = [];
    if (! array_key_exists($flag, $p_times))
        $p_times[$flag] = [ 'total' => 0, 'open' => 0 ];
    $p_times[$flag]['open'] = microtime(true);
}

function p_close($flag)
{
    global $p_times;
    if (isset($p_times[$flag]['open'])) {
        $p_times[$flag]['total'] += (microtime(true) - $p_times[$flag]['open']);
        unset($p_times[$flag]['open']);
    }
}

function p_dump()
{
    global $p_times;
    $dump = [];
    $sum  = 0;
    foreach ($p_times as $flag => $info) {
        $dump[$flag]['elapsed'] = $info['total'];
        $sum += $info['total'];
    }
    foreach ($dump as $flag => $info) {
        $dump[$flag]['percent'] = $dump[$flag]['elapsed']/$sum;
    }
    return $dump;
}

Example:

<?php

p_open('foo');
sleep(1);
p_open('bar');
sleep(2);
p_open('baz');
sleep(3);
p_close('baz');
sleep(2);
p_close('bar');
sleep(1);
p_close('foo');

var_dump(p_dump());

Yields:

array:3 [
  "foo" => array:2 [
    "elapsed" => 9.000766992569
    "percent" => 0.4736904954747
  ]
  "bar" => array:2 [
    "elapsed" => 7.0004580020905
    "percent" => 0.36841864946596

require 5.013002; # or better:    use Syntax::Construct qw(/r);
print "bla: ", $myvar =~ s/a/b/r, "\n";

See perl5132delta:

The substitution operator now supports a /r option that copies the input variable, carries out the substitution on the copy and returns the result. The original remains unmodified.

my $old = 'cat';
my $new = $old =~ s/cat/dog/r;
# $old is 'cat' and $new is 'dog'

The answer is simply that it makes no difference how the segue is triggered.

The prepareForSegue:sender: method is called in any case and this is where you pass your parameters across.

Try this:

Date date = new Date(logEvent.timeSTamp);
DateFormat formatter = new SimpleDateFormat("HH:mm:ss.SSS");
formatter.setTimeZone(TimeZone.getTimeZone("UTC"));
String dateFormatted = formatter.format(date);

See SimpleDateFormat for a description of other format strings that the class accepts.

See runnable example using input of 1200 ms.

This work for me for a location in India:

SET GLOBAL time_zone = "Asia/Calcutta";
SET time_zone = "+05:30";
SET @@session.time_zone = "+05:30";

Check out php-ip-2-country from code.google. The database they provide is updated daily, so it is not necessary to connect to an outside server for the check if you host your own SQL server. So using the code you would only have to type:

<?php
$ip = $_SERVER['REMOTE_ADDR'];

if(!empty($ip)){
        require('./phpip2country.class.php');

        /**
         * Newest data (SQL) avaliable on project website
         * @link http://code.google.com/p/php-ip-2-country/
         */
        $dbConfigArray = array(
                'host' => 'localhost', //example host name
                'port' => 3306, //3306 -default mysql port number
                'dbName' => 'ip_to_country', //example db name
                'dbUserName' => 'ip_to_country', //example user name
                'dbUserPassword' => 'QrDB9Y8CKMdLDH8Q', //example user password
                'tableName' => 'ip_to_country', //example table name
        );

        $phpIp2Country = new phpIp2Country($ip,$dbConfigArray);
        $country = $phpIp2Country->getInfo(IP_COUNTRY_NAME);
        echo $country;
?>

Example Code (from the resource)

<?
require('phpip2country.class.php');

$dbConfigArray = array(
        'host' => 'localhost', //example host name
        'port' => 3306, //3306 -default mysql port number
        'dbName' => 'ip_to_country', //example db name
        'dbUserName' => 'ip_to_country', //example user name
        'dbUserPassword' => 'QrDB9Y8CKMdLDH8Q', //example user password
        'tableName' => 'ip_to_country', //example table name
);

$phpIp2Country = new phpIp2Country('213.180.138.148',$dbConfigArray);

print_r($phpIp2Country->getInfo(IP_INFO));
?>

Output

It is a string formatting syntax (which it borrows from C).

Please see "PyFormat":

Python supports formatting values into strings. Although this can include very complicated expressions, the most basic usage is to insert values into a string with the %s placeholder.

Edit: Here is a really simple example:

#Python2
name = raw_input("who are you? ")
print "hello %s" % (name,)

#Python3+
name = input("who are you? ")
print("hello %s" % (name,))

The %s token allows me to insert (and potentially format) a string. Notice that the %s token is replaced by whatever I pass to the string after the % symbol. Notice also that I am using a tuple here as well (when you only have one string using a tuple is optional) to illustrate that multiple strings can be inserted and formatted in one statement.

data: '{"jewellerId":"' + filter + '","locale":"' + locale + '"}',

Based on semver, you can use

• Hyphen Ranges X.Y.Z - A.B.C 1.2.3-2.3.4 Indicates >=1.2.3 <=2.3.4

• X-Ranges 1.2.x 1.X 1.2.*

• Tilde Ranges ~1.2.3 ~1.2 Indicates allowing patch-level changes or minor version changes.

• Caret Ranges ^1.2.3 ^0.2.5 ^0.0.4

  Allows changes that do not modify the left-most non-zero digit in the [major, minor, patch] tuple

  • ^1.2.x (means >=1.2.0 <2.0.0)
  • ^0.0.x (means >=0.0.0 <0.1.0)
  • ^0.0 (means >=0.0.0 <0.1.0)

Depends on what type of button you are using

<input type='button' value='Add' id='btnAddProfile'>
$("#btnAddProfile").attr('value', 'Save'); //versions older than 1.6

<input type='button' value='Add' id='btnAddProfile'>
$("#btnAddProfile").prop('value', 'Save'); //versions newer than 1.6

<!-- Different button types-->

<button id='btnAddProfile' type='button'>Add</button>
$("#btnAddProfile").html('Save');

Your button could also be a link. You'll need to post some HTML for a more specific answer.

EDIT : These will work assuming you've wrapped it in a .click() call, of course

EDIT 2 : Newer jQuery versions (from > 1.6) use .prop rather than .attr

EDIT 3 : If you're using jQuery UI, you need to use DaveUK's method (below) of adjusting the text property

<video id="myvideo">
  <source src="path/to/movie.mp4" />
</video>

<p onclick="toggleControls();">Toggle</p>

<script>
var video = document.getElementById("myvideo");

function toggleControls() {
  if (video.hasAttribute("controls")) {
     video.removeAttribute("controls")   
  } else {
     video.setAttribute("controls","controls")   
  }
}
</script>

This is maybe the wrong answer for you. But this was the first hit on Google when I tried to solve my problem. With that said...

The same error message occurred for me as well, but when I tried to run IIS Express through Visual Studio.

My problem was that I mistakenly commited my applicationhost.config to TFS. Later when I tried to run the project on my laptop after getting the latest commits. that's when the error occurred.

I found that the virtual directory path was wrong.

<virtualDirectory path="/" physicalPath="C:\Users\user1\Documents\Visual Studio 2015\Projects\ProjectName\ProjectName\ProjectName.Web" />

Hope that this help somebody!

This is my first post, so be gentle :)

Use defaultValue to preselect the values for Select.

<Select defaultValue={[{ value: category.published, label: 'Publish' }]} options={statusOptions} onChange={handleStatusChange} />

You have to just add the index_col=False parameter

df1 = pd.read_csv('foo.csv',
     header=0,
     index_col=False,
     names=["dummy", "date", "loc", "x"], 
     usecols=["dummy", "date", "loc", "x"],
     parse_dates=["date"])
  print df1

In case anyone are still interested in this subject, I find that the best approach for filtering lists is to create a generic Filter class and use it with some base reflection/generics techniques contained in the Java old school SDK package. Here's what I did:

public class GenericListFilter<T> extends Filter {

    /**
     * Copycat constructor
     * @param list  the original list to be used
     */
    public GenericListFilter (List<T> list, String reflectMethodName, ArrayAdapter<T> adapter) {
        super ();

        mInternalList = new ArrayList<>(list);
        mAdapterUsed  = adapter;

        try {
            ParameterizedType stringListType = (ParameterizedType)
                    getClass().getField("mInternalList").getGenericType();
            mCompairMethod =
                    stringListType.getActualTypeArguments()[0].getClass().getMethod(reflectMethodName);
        }
        catch (Exception ex) {
            Log.w("GenericListFilter", ex.getMessage(), ex);

            try {
                if (mInternalList.size() > 0) {
                    T type = mInternalList.get(0);
                    mCompairMethod = type.getClass().getMethod(reflectMethodName);
                }
            }
            catch (Exception e) {
                Log.e("GenericListFilter", e.getMessage(), e);
            }

        }
    }

    /**
     * Let's filter the data with the given constraint
     * @param constraint
     * @return
     */
    @Override protected FilterResults performFiltering(CharSequence constraint) {
        FilterResults results = new FilterResults();
        List<T> filteredContents = new ArrayList<>();

        if ( constraint.length() > 0 ) {
            try {
                for (T obj : mInternalList) {
                    String result = (String) mCompairMethod.invoke(obj);
                    if (result.toLowerCase().startsWith(constraint.toString().toLowerCase())) {
                        filteredContents.add(obj);
                    }
                }
            }
            catch (Exception ex) {
                Log.e("GenericListFilter", ex.getMessage(), ex);
            }
        }
        else {
            filteredContents.addAll(mInternalList);
        }

        results.values = filteredContents;
        results.count  = filteredContents.size();
        return results;
    }

    /**
     * Publish the filtering adapter list
     * @param constraint
     * @param results
     */
    @Override protected void publishResults(CharSequence constraint, FilterResults results) {
        mAdapterUsed.clear();
        mAdapterUsed.addAll((List<T>) results.values);

        if ( results.count == 0 ) {
            mAdapterUsed.notifyDataSetInvalidated();
        }
        else {
            mAdapterUsed.notifyDataSetChanged();
        }
    }

    // class properties
    private ArrayAdapter<T> mAdapterUsed;
    private List<T> mInternalList;
    private Method  mCompairMethod;
}

And afterwards, the only thing you need to do is to create the filter as a member class (possibly within the View's "onCreate") passing your adapter reference, your list, and the method to be called for filtering:

this.mFilter = new GenericFilter<MyObjectBean> (list, "getName", adapter);

The only thing missing now, is to override the "getFilter" method in the adapter class:

@Override public Filter getFilter () {
     return MyViewClass.this.mFilter;
}

All done! You should successfully filter your list - Of course, you should also implement your filter algorithm the best way that describes your need, the code bellow is just an example.. Hope it helped, take care.

If by "application startup" you mean "application context startup", then yes, there are many ways to do this, the easiest (for singletons beans, anyway) being to annotate your method with @PostConstruct. Take a look at the link to see the other options, but in summary they are:

• Methods annotated with @PostConstruct
• afterPropertiesSet() as defined by the InitializingBean callback interface
• A custom configured init() method

Technically, these are hooks into the bean lifecycle, rather than the context lifecycle, but in 99% of cases, the two are equivalent.

If you need to hook specifically into the context startup/shutdown, then you can implement the Lifecycle interface instead, but that's probably unnecessary.

No longer works for spreadsheets Protected with Excel 2013 or later -- they improved the pw hash. So now need to unzip .xlsx and hack the internals.

Another way to do this and this works well if you have multiple columns to convert to datetime.

cols = ['date1','date2']
df[cols] = df[cols].apply(pd.to_datetime)

I did not have rights to create functions but had text like

["blahblah012345679"]

And needed to extract the numbers out of the middle

Note this assumes the numbers are grouped together and not at the start and end of the string.

select substring(column_name,patindex('%[0-9]%', column_name),patindex('%[0-9][^0-9]%', column_name)-patindex('%[0-9]%', column_name)+1)
from table name

That's how I obtained my:

private class SessionStatusCallback implements Session.StatusCallback {
        @Override
        public void call(Session session, SessionState state, Exception exception) {

            if (exception != null) {
                new AlertDialog.Builder(FriendActivity.this)
                        .setTitle(R.string.login_failed_dialog_title)
                        .setMessage(exception.getMessage())
                        .setPositiveButton(R.string.ok_button, null)
                        .show();
            }

So when you re trying to enter without the key, an exception will occur. Facebook put the RIGHT key into this exception. All you need to do is to copy it.

By default node package is nodejs, so use

$ nodejs -v

or

$ nodejs --version 

You can make a link using

$ sudo ln -s /usr/bin/nodejs /usr/bin/node

then u can use

$ node --version

or

$ node -v

As @Ofer said, when you are using another libraries or modules, you should import all of them inside the if __name__ == '__main__':

So, in my case, ended like this:

if __name__ == '__main__':

    import os
    import pandas as pd

In my case and while installing VS 2015 on Windows7 64x SP1, I experienced the same so tried to cancel and download/install the KBKB2999226 separately and for some reason the standalone update installer also get stuck searching for updates.

Here what I did:

1. When the VS installer stuck at the KB2999226 update I clicked cancel.
2. Installer took me back to confirm cancellation, waited for a while then opened the windows task manager and ended the process of wuse.exe (windows standalone update installer)
3. On the VS installer clicked "No" to return to installation process. The process was completed without errors.

You are dividing by rr which may be 0.0. Check if rr is zero and do something reasonable other than using it in the denominator.

I think this is the best option.

temp = [line.strip() for line in file.readlines()]

Using latest Jenkins version 2.7.4 which is also having a bug for existing jobs.

1. Add new JDKs through Manage Jenkins -> Global Tool Configuration -> JDK ** If you edit current job then JDK dropdown is not showing (bug)

2. Hit http://your_jenkin_server:8080/restart and restart the server

3. Re-configure job

Now, you should see JDK dropdown in "job name" -> Configure in Jenkins web ui. It will list all JDKs available in Jenkins configuration.

You can use within <td> tag css : display:inline-block

One approach: if you can guarantee unrelated applications won't use the files in a conflicting manner, just create a pool of files of varying sizes in a specific directory, then create links to them when needed.

For example, have a pool of files called:

• /home/bigfiles/512M-A
• /home/bigfiles/512M-B
• /home/bigfiles/1024M-A
• /home/bigfiles/1024M-B

Then, if you have an application that needs a 1G file called /home/oracle/logfile, execute a "ln /home/bigfiles/1024M-A /home/oracle/logfile".

If it's on a separate filesystem, you will have to use a symbolic link.

The A/B/etc files can be used to ensure there's no conflicting use between unrelated applications.

The link operation is about as fast as you can get.

You can also use inspect.getdoc. It cleans up the __doc__ by normalizing tabs to spaces and left shifting the doc body to remove common leading spaces.

The only way that worked for me is creating a Boolean variable that I set to true when I add the event. Then I ask: If the variable is false, I add the event.

bool alreadyAdded = false;

This variable can be global.

if(!alreadyAdded)
{
    myClass.MyEvent += MyHandler;
    alreadyAdded = true;
}

import csv
from sys import argv

d = open("mydata.csv", "r")

db = []

for line in csv.reader(d):
    db.append(line)

# the rest of your code with 'db' filled with your list of lists as rows and columbs of your csv file.

Further to Stephen Weinberg's answer, I have since implemented a handy tool called iojson, which helps to populate data to an existing object easily as well as encoding the existing object to a JSON string. A iojson middleware is also provided to work with other middlewares. More examples can be found at https://github.com/junhsieh/iojson

Example:

func main() {
    jsonStr := `{"Status":true,"ErrArr":[],"ObjArr":[{"Name":"My luxury car","ItemArr":[{"Name":"Bag"},{"Name":"Pen"}]}],"ObjMap":{}}`

    car := NewCar()

    i := iojson.NewIOJSON()

    if err := i.Decode(strings.NewReader(jsonStr)); err != nil {
        fmt.Printf("err: %s\n", err.Error())
    }

    // populating data to a live car object.
    if v, err := i.GetObjFromArr(0, car); err != nil {
        fmt.Printf("err: %s\n", err.Error())
    } else {
        fmt.Printf("car (original): %s\n", car.GetName())
        fmt.Printf("car (returned): %s\n", v.(*Car).GetName())

        for k, item := range car.ItemArr {
            fmt.Printf("ItemArr[%d] of car (original): %s\n", k, item.GetName())
        }

        for k, item := range v.(*Car).ItemArr {
            fmt.Printf("ItemArr[%d] of car (returned): %s\n", k, item.GetName())
        }
    }
}

Sample output:

car (original): My luxury car
car (returned): My luxury car
ItemArr[0] of car (original): Bag
ItemArr[1] of car (original): Pen
ItemArr[0] of car (returned): Bag
ItemArr[1] of car (returned): Pen

I assume one uses print_r for debugging. I would then suggest using libraries like Kint. This allows displaying big arrays in a readable format:

$data = [['Natural Child 1', 'Natural Child 2', 'Natural Child 3']];
Kint::dump($data, $_SERVER);

If you're making a dictionary only to make a list of tuples, as creating dicts like you are may be a pain, you might look into using zip()

Its especialy useful if you've got one heading, and multiple rows. For instance if I assume that you want Olympics stats for countries:

headers = ['Capital', 'Food', 'Year']
countries = [
    ['London', 'Fish & Chips', '2012'],
    ['Beijing', 'Noodles', '2008'],
]

for olympics in countries:
    print zip(headers, olympics)

gives

[('Capital', 'London'), ('Food', 'Fish & Chips'), ('Year', '2012')]
[('Capital', 'Beijing'), ('Food', 'Noodles'), ('Year', '2008')]

Don't know if thats the end goal, and my be off topic, but it could be something to keep in mind.

If you want to generate a file in the Windows, then, please follow the below steps:

1. Go to a directory where you want to save the generated file
2. Open the command prompt on that directory
3. Run this fsutil file createnew [filename].[extension] [# of bytes] command. For example fsutil file createnew test.pdf 999999999
4. 95.3 MB File will be generated

Update: The generated file will not be a valid pdf file. It just holds the given size.

Open the Servers view -> double click tomcat -> drop down the Timeouts section you can increase the startup time for each particular server. like 45 to 450

Another way

=IF(SUMPRODUCT(--(NOT(ISERR(SEARCH({"Gingrich","Obama","Romney"},C1)))))>0,"1","")

Also, if you keep a list of values in, say A1 to A3, then you can use

=IF(SUMPRODUCT(--(NOT(ISERR(SEARCH($A$1:$A$3,C1)))))>0,"1","")

The wildcards are not necessary at all in the Search() function, since Search() returns the position of the found string.

If you want only the name of the folder that is the immediate parent of the file provided as an argument and not the absolute path to that file:

os.path.split(os.path.dirname(currentDir))[1]

i.e. with a currentDir value of /home/user/path/to/myfile/file.ext

The above command will return:

myfile

A full outer join combines a left outer join and a right outer join. The result set returns rows from both tables where the conditions are met but returns null columns where there is no match.

A cross join is a Cartesian product that does not require any condition to join tables. The result set contains rows and columns that are a multiplication of both tables.

The problem is the MySQL client C library, which most MySQL APIs are built on. The problem is that the C library doesn't support simultaneous execution of queries, so all APIs built on top of that also do not. Even if you use unbuffered queries. This is one reason why the asynchronous MySQL API was written. It communicates directly with the MySQL server using TCP and the wire-protocol does support simultaneous queries.

Your solution is to either modify the algorithm so you don't need to have both in progress at once, or change them to use buffered queries, which is probably one of the original reasons for their existence in the C library (the other is to provide a kind of cursor).

I don't think you can!

/home/export/user1 $ sqlplus / 
> @script1.sql
> HOST CD /home/export/user2
> @script2.sql

script2.sql has to be in /home/export/user1.

You either use the full path, or exit the script and start sqlplus again from the right directory.

#!/bin/bash
oraenv .
cd /home/export/user1
sqlplus / @script1.sql
cd /home/export/user2
sqlplus / @script2.sql

(something like that - doing this from memory!)

Linux, Apache, MySQL and PHP. free and open-source software. For example, an equivalent installation on the Microsoft Windows family of operating systems is known as WAMP. and for mac as MAMP. and XAMPP for both of them

The tab character is \t. Notice the use of " instead of '.

$chunk = "abc\tdef\tghi";

PHP Strings - Double quoted

If the string is enclosed in double-quotes ("), PHP will interpret more escape sequences for special characters:

...

\t horizontal tab (HT or 0x09 (9) in ASCII)

Also, let me recommend the fputcsv() function which is for the purpose of writing CSV files.

CSS can't change the tooltip appearance. It is browser/OS-dependent. If you want something different you'll have to use Javascript to generate markup when you hover over the element instead of the default tooltip.

int[] numbers = { 1, 3, 4, 9, 2 };
numbers = numbers.Except(new int[]{4}).ToArray();

I found the answer :)

Use JsonPath or XmlPath (in case you have XML) to get data from the response body.

In my case:

JsonPath jsonPath = new JsonPath(responseBody);
int user_id = jsonPath.getInt("user_id");

For individual variables you want to make available on a one off basis you can make it part of the command.

sudo http_proxy=$http_proxy wget "http://stackoverflow.com"

To make a div in center. There isn't any need to assign the width of the div.

A working demo is here:

http://jsfiddle.net/6yukdmwq/

    .container {
        width: 100%;
        height: 500px;
        display: table;
        border: 1px solid red;
        text-align: center;}

    .center {
        display: table-cell;
        vertical-align: middle;
    }

    .content {
        display: inline-block;
        text-align: center;
        border: 1px solid green;
    }

    <section class="container">
        <div class="center">
            <div class="content">
                <h1>Helllo Center Text</h1>
            </div>
        </div>
    </section>

earl's answer gives you the solution, but I thought I'd add what the problem is that's causing your IllegalStateException. You're calling group(1) without having first called a matching operation (such as find()). This isn't needed if you're just using $1 since the replaceAll() is the matching operation.

No, it's not possible. If it runs on the client browser, it must be downloaded by the client browser. It's pretty trivial to use Fiddler to inspect the HTTP session and get any downloaded js files.

There are tricks you can use. One of the most obvious is to employ a javascript obfuscator.

Then again, obfuscation only prevents casual snooping, and doesnt prevent people from lifting and using your code.

You can try compiled action script in the form of a flash movie.

Using vmin and vmax forces the range for the colors. Here's an example:

import matplotlib as m
import matplotlib.pyplot as plt
import numpy as np

cdict = {
  'red'  :  ( (0.0, 0.25, .25), (0.02, .59, .59), (1., 1., 1.)),
  'green':  ( (0.0, 0.0, 0.0), (0.02, .45, .45), (1., .97, .97)),
  'blue' :  ( (0.0, 1.0, 1.0), (0.02, .75, .75), (1., 0.45, 0.45))
}

cm = m.colors.LinearSegmentedColormap('my_colormap', cdict, 1024)

x = np.arange(0, 10, .1)
y = np.arange(0, 10, .1)
X, Y = np.meshgrid(x,y)

data = 2*( np.sin(X) + np.sin(3*Y) )

def do_plot(n, f, title):
    #plt.clf()
    plt.subplot(1, 3, n)
    plt.pcolor(X, Y, f(data), cmap=cm, vmin=-4, vmax=4)
    plt.title(title)
    plt.colorbar()

plt.figure()
do_plot(1, lambda x:x, "all")
do_plot(2, lambda x:np.clip(x, -4, 0), "<0")
do_plot(3, lambda x:np.clip(x, 0, 4), ">0")
plt.show()

I had modified my answer tons of times and realized i don't have to say anything, python had explained itself already.

a = 'string'
a.replace('t', '_')
print(a)
>>> 'string'

a = a.replace('t', '_')
print(a)
>>> 's_ring'

b = 100
b + 1
print(b)
>>> 100

b = b + 1
print(b)
>>> 101

def test_id(arg):
    c = id(arg)
    arg = 123
    d = id(arg)
    return

a = 'test ids'
b = id(a)
test_id(a)
e = id(a)

# b = c  = e != d

# this function do change original value
del change_like_mutable(arg):
    arg.append(1)
    arg.insert(0, 9)
    arg.remove(2)
    return

test_1 = [1, 2, 3]
change_like_mutable(test_1)



# this function doesn't 
def wont_change_like_str(arg):
     arg = [1, 2, 3]
     return


test_2 = [1, 1, 1]
wont_change_like_str(test_2)
print("Doesn't change like a imutable", test_2)

This devil is not the reference / value / mutable or not / instance, name space or variable / list or str, IT IS THE SYNTAX, EQUAL SIGN.
