I was getting the same error in my IBM Websphere with c3p0 jar files. I have Oracle 10g database. I simply added the oraclejdbc.jar files in the Application server JVM in IBM Classpath using Websphere Console and the error was resolved.

The oraclejdbc.jar should be set with your C3P0 jar files in your Server Class path whatever it be tomcat, glassfish of IBM.

If you add your site to "Local Intranet" in

Chrome > Options > Under the Hood > Change Proxy Settings > Security (tab) > Local Intranet/Sites > Advanced.

Add you site URL here and it will work.

Update for New Version of Chrome

If you really want an iterator-free solution, you can use numpy and its array round function.

import numpy as np
myList = list(np.around(np.array(myList),2))

Do aman 2 sendfile. You only need to open the source file on the client and destination file on the server, then call sendfile and the kernel will chop and move the data.

Probably very late to the answer but I just read this while preparing for my 70-480 exam, and found this to work -

var elem = document.getElementById('myCanvas');
elem.onclick = function() { alert("hello world"); }

Notice the event as onclick instead of onClick.

Here is one possiblity for you if you are using Bootstrap 3

I'm using the resposive table code from http://getbootstrap.com/css/#tables-responsive

ie:

<div class="table-responsive">
<table class="table">
...
</table>
</div>

First of all, you do not have to develop any form yourself : phpMyAdmin, depending on its configuration (i.e. config.inc.php) will display an identification form, asking for a login and password.

To get that form, you should not use :

$cfg['Servers'][$i]['auth_type'] = 'config';

But you should use :

$cfg['Servers'][$i]['auth_type'] = 'cookie';

(At least, that's what I have on a server which prompts for login/password, using a form)

For more informations, you can take a look at the documentation :

• Using authentication modes
• Configuration, which states (quoting) :

'config' authentication ($auth_type = 'config') is the plain old way: username and password are stored in config.inc.php.

'cookie' authentication mode ($auth_type = 'cookie') as introduced in 2.2.3 allows you to log in as any valid MySQL user with the help of cookies.
Username and password are stored in cookies during the session and password is deleted when it ends.

Hasan Badshah's answer worked for me, but the method is slated to be deprecated and may be problematic for others going forward. Following the MDN web docs on alternative methods, I landed here: PerformanceNavigationTiming.type

if (performance.getEntriesByType("navigation")[0].type === 'back_forward') {
  // back or forward button functionality
}

This doesn't directly solve for back button over the forward button, but was good enough for what I needed. In the docs they detail the available event data that may be helpful with solving your specific needs:

function print_nav_timing_data() {
  // Use getEntriesByType() to just get the "navigation" events
  var perfEntries = performance.getEntriesByType("navigation");

  for (var i=0; i < perfEntries.length; i++) {
    console.log("= Navigation entry[" + i + "]");
    var p = perfEntries[i];
    // dom Properties
    console.log("DOM content loaded = " + (p.domContentLoadedEventEnd - 
    p.domContentLoadedEventStart));
    console.log("DOM complete = " + p.domComplete);
    console.log("DOM interactive = " + p.interactive);

    // document load and unload time
    console.log("document load = " + (p.loadEventEnd - p.loadEventStart));
    console.log("document unload = " + (p.unloadEventEnd - 
    p.unloadEventStart));

    // other properties
    console.log("type = " + p.type);
    console.log("redirectCount = " + p.redirectCount);
  }
}

According to the Docs at the time of this post it is still in a working draft state and is not supported in IE or Safari, but that may change by the time it is finished. Check the Docs for updates.

In my case, I had to specify messageEncoding to Mtom in app.config of the client application like that:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <startup> 
        <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.6.1" />
    </startup>
    <system.serviceModel>
        <bindings>
            <basicHttpBinding>
                <binding name="IntegrationServiceSoap" messageEncoding="Mtom"/>
            </basicHttpBinding>
        </bindings>
        <client>
            <endpoint address="http://localhost:29495/IntegrationService.asmx"
                binding="basicHttpBinding" bindingConfiguration="IntegrationServiceSoap"
                contract="IntegrationService.IntegrationServiceSoap" name="IntegrationServiceSoap" />
        </client>
    </system.serviceModel>
</configuration>

Both my client and server use basicHttpBinding. I hope this helps the others :)

I use a fairly low tech solution. I format the code using this online syntax highlighting tool then just paste it into the blog

I used just the lines below and it worked. I just wanted to compile VirtualBox and VMWare WorkStation using kernel 4.8.10 on Ubuntu 14.04. Initially, most things were not working for example graphics and networking. I was lucky that VMWare workstation requested for gcc 6.2.0. I couldn't start my Genymotion Android emulators because virtualbox was down. Will post results later if necessary.

You have to wrap the entire url statement in the bypassSecurityTrustStyle:

<div class="header" *ngIf="image" [style.background-image]="image"></div>

And have

this.image = this.sanitization.bypassSecurityTrustStyle(`url(${element.image})`);

Otherwise it is not seen as a valid style property

ACID and BASE are consistency models for RDBMS and NoSQL respectively. ACID transactions are far more pessimistic i.e. they are more worried about data safety. In the NoSQL database world, ACID transactions are less fashionable as some databases have loosened the requirements for immediate consistency, data freshness and accuracy in order to gain other benefits, like scalability and resiliency.

BASE stands for -

• Basic Availability - The database appears to work most of the time.
• Soft-state - Stores don't have to be write-consistent, nor do different replicas have to be mutually consistent all the time.
• Eventual consistency - Stores exhibit consistency at some later point (e.g., lazily at read time).

Therefore BASE relaxes consistency to allow the system to process request even in an inconsistent state.

Example: No one would mind if their tweet were inconsistent within their social network for a short period of time. It is more important to get an immediate response than to have a consistent state of users' information.

data.removeAll(data); will do the work, I think.

I've had this happen (405 method not allowed) when the web api post method I was calling had primitive types for parameters, instead of a complex type that was accessed from the body. Like so:

This worked:

 [Route("update"), Authorize, HttpPost]
  public int Update([FromBody] updateObject update)

This didn't:

 [Route("update"), Authorize, HttpPost]
 public int Update(string whatever, int whatever, string whatever)

In IE9, it is possible with purely a hack as advised by @Spudley. Since you've customized height and width of the div and select, you need to change div:before css to match yours.

In case if it is IE10 then using below css3 it is possible

select::-ms-expand {
    display: none;
}

However if you're interested in jQuery plugin, try Chosen.js or you can create your own in js.

Table with papging, sort and filter

You are correct that without a parent node, solution with traversal will give you O(n) time complexity.

Traversal approach Suppose you are finding LCA for node A and B, the most straightforward approach is to first get the path from root to A and then get the path from root to B. Once you have these two paths, you can easily iterate over them and find the last common node, which is the lowest common ancestor of A and B.

Recursive solution Another approach is to use recursion. First, we can get LCA from both left tree and right tree (if exists). If the either of A or B is the root node, then the root is the LCA and we just return the root, which is the end point of the recursion. As we keep divide the tree into sub-trees, eventually, we’ll hit either A and B.

To combine sub-problem solutions, if LCA(left tree) returns a node, we know that both A and B locate in left tree and the returned node is the final result. If both LCA(left) and LCA(right) return non-empty nodes, it means A and B are in left and right tree respectively. In this case, the root node is the lowest common node.

Check Lowest Common Ancestor for detailed analysis and solution.

My 2 pennies:-

 collection.Count(v => (v.PropertyToUpdate = newValue) == null);

The problem is that the checkout takes place on a laptop and in this case subversion can not cope with the off-line synchronization. The problem is reproducable on an other laptop while on a desktop I have no problem checking out the same repository.

I hope this answer wil help you, it took me quite long to find out.

The built-in webserver is hardwired to use Default.aspx as the default page.

The project must have atleast an empty Default.aspx file to overcome the Directory Listing problem for Global.asax.

:)

Once you add that empty file all requests can be handled in one location.

public class Global : System.Web.HttpApplication
{
    protected void Application_BeginRequest(object sender, EventArgs e)
    {
        this.Response.Write("hi@ " + this.Request.Path + "?" + this.Request.QueryString);
        this.Response.StatusCode = 200;
        this.Response.ContentType = "text/plain";

        this.Response.End();
    }
}

You can use a FileReader object to read text file here is example code:

  <div id="page-wrapper">

        <h1>Text File Reader</h1>
        <div>
            Select a text file: 
            <input type="file" id="fileInput">
        </div>
        <pre id="fileDisplayArea"><pre>

    </div>
<script>
window.onload = function() {
        var fileInput = document.getElementById('fileInput');
        var fileDisplayArea = document.getElementById('fileDisplayArea');

        fileInput.addEventListener('change', function(e) {
            var file = fileInput.files[0];
            var textType = /text.*/;

            if (file.type.match(textType)) {
                var reader = new FileReader();

                reader.onload = function(e) {
                    fileDisplayArea.innerText = reader.result;
                }

                reader.readAsText(file);    
            } else {
                fileDisplayArea.innerText = "File not supported!"
            }
        });
}

</script>

Here is the codepen demo

If you have a fixed file to read every time your application load then you can use this code :

<script>
var fileDisplayArea = document.getElementById('fileDisplayArea');
function readTextFile(file)
{
    var rawFile = new XMLHttpRequest();
    rawFile.open("GET", file, false);
    rawFile.onreadystatechange = function ()
    {
        if(rawFile.readyState === 4)
        {
            if(rawFile.status === 200 || rawFile.status == 0)
            {
                var allText = rawFile.responseText;
                fileDisplayArea.innerText = allText 
            }
        }
    }
    rawFile.send(null);
}

readTextFile("file:///C:/your/path/to/file.txt");
</script>

The key is that they allow concurrent access and modification safely. They're commonly used as counters in a multithreaded environment - before their introduction this had to be a user written class that wrapped up the various methods in synchronized blocks.

You can also just delay some operation this way:

setTimeout(function (){

  // Something you want delayed.

}, 5000); // How long do you want the delay to be (in milliseconds)? 

This example selects a new Range of Cells defined by the current cell to a cell 5 to the right.

Note that .Offset takes arguments of Offset(row, columns) and can be quite useful.

Sub testForStackOverflow()
    Range(ActiveCell, ActiveCell.Offset(0, 5)).Copy
End Sub

I faced the same issue when I had to pass a pom version to a downstream Rundeck job.

What I did, was using parameters injection via a properties file as such:

1) Creating properties in properties file via shell :

Build actions:

• Execute a shell script
• Inject environment variables

E.g : properties definition

2) Passing defined properties to the downstream job : Post Build Actions :

• Trigger parameterized build on other project
• Add parameters : Current build parameters
• Add parameters : predefined parameters

E.g : properties sending

3) It was then possible to use $POM_VERSION as such in the downstream Rundeck job.

/!\ Jenkins Version : 1.636

/!\ For some reason when creating the triggered build, it was necessary to add the option 'Current build parameters' to pass the properties.

use the following inside the body tag

<body onclick="theFunction(event)">

then use in javascript the following function to get the ID

<script>
function theFunction(e)
{ alert(e.target.id);}

Type info variables to list "All global and static variable names".

Type info locals to list "Local variables of current stack frame" (names and values), including static variables in that function.

Type info args to list "Arguments of the current stack frame" (names and values).

Angular's $http has a cache built in. According to the docs:

cache – {boolean|Object} – A boolean value or object created with $cacheFactory to enable or disable caching of the HTTP response. See $http Caching for more information.

Boolean value

So you can set cache to true in its options:

$http.get(url, { cache: true}).success(...);

or, if you prefer the config type of call:

$http({ cache: true, url: url, method: 'GET'}).success(...);

Cache Object

You can also use a cache factory:

var cache = $cacheFactory('myCache');

$http.get(url, { cache: cache })

You can implement it yourself using $cacheFactory (especially handly when using $resource):

var cache = $cacheFactory('myCache');

var data = cache.get(someKey);

if (!data) {
   $http.get(url).success(function(result) {
      data = result;
      cache.put(someKey, data);
   });
}

You need to treat a table valued udf like a table, eg JOIN it

select Emp_Id 
from Employee E JOIN dbo.Splitfn(@Id,',') CSV ON E.Emp_Id = CSV.items 

as explained in above answers Also, to return only one field from the entire array you can use projection into find. and use $

db.getCollection("sizer").find(
  { awards: { $elemMatch: { award: "National Medal", year: 1975 } } },
  { "awards.$": 1, name: 1 }
);

will be reutrn

{
    _id: 1,
    name: {
        first: 'John',
        last: 'Backus'
    },
    awards: [
        {
            award: 'National Medal',
            year: 1975,
            by: 'NSF'
        }
    ]
}

Or maybe even easier

grep -R put **/*bills*

The ** glob syntax means "any depth of directories". It will work in Zsh, and I think recent versions of Bash too.

Your root logger definition is a bit confused. See the log4j documentation.

This is a standard Java properties file, which means that lines are treated as key=value pairs. Your second log4j.rootLogger line is overwriting the first, which explains why you aren't seeing anything on the console appender.

You need to merge your two rootLogger definitions into one. It looks like you're trying to have DEBUG messages go to the console and INFO messages to the file. The root logger can only have one level, so you need to change your configuration so that the appenders have appropriate levels.

While I haven't verified that this is correct, I'd guess it'll look something like this:

log4j.rootLogger=DEBUG,console,file
log4j.appender.console=org.apache.log4j.ConsoleAppender
log4j.appender.file=org.apache.log4j.RollingFileAppender

Note that you also have an error in casing - you have console lowercase in one place and in CAPS in another.

I'll explain it in a simple way.

Generics defined at Class level are completely separate from the generics defined at the (static) method level.

class Greet<T> {

    public static <T> void sayHello(T obj) {
        System.out.println("Hello " + obj);
    }
}

When you see the above code anywhere, please note that the T defined at the class level has nothing to do with the T defined in the static method. The following code is also completely valid and equivalent to the above code.

class Greet<T> {

    public static <E> void sayHello(E obj) {
        System.out.println("Hello " + obj);
    }
}

Why the static method needs to have its own generics separate from those of the Class?

This is because, the static method can be called without even instantiating the Class. So if the Class is not yet instantiated, we do not yet know what is T. This is the reason why the static methods needs to have its own generics.

So, whenever you are calling the static method,

Greet.sayHello("Bob");
Greet.sayHello(123);

JVM interprets it as the following.

Greet.<String>sayHello("Bob");
Greet.<Integer>sayHello(123);

Both giving the same outputs.

Hello Bob
Hello 123

Table or record locking is available in Access during data writes. You can control the Default record locking through Tools | Options | Advanced tab:

1. No Locks
2. All Records
3. Edited Record

You can set this on a form's Record Locks or in your DAO/ADO code for specific needs.

Transactions shouldn't be a problem if you use them correctly.

Best practice: Separate your tables from All your other code. Give each user their own copy of the code file and then share the data file on a network server. Work on a 'test' copy of the code (and a link to a test data file) and then update user's individual code files separately. If you need to make data file changes (add tables, columns, etc), you will have to have all users get out of the application to make the changes.

See other answers for Oracle comparison.

You can do :

document.forms["loginForm"].submit()

But this won't call the onclick action of your button, so you will need to call it by hand.

Be aware that you must use the name of your form and not the id to access it.

If you are using the JPA annotations, you can use @PrePersist and @PreUpdate event hooks do this:

@Entity
@Table(name = "entities")    
public class Entity {
  ...

  private Date created;
  private Date updated;

  @PrePersist
  protected void onCreate() {
    created = new Date();
  }

  @PreUpdate
  protected void onUpdate() {
    updated = new Date();
  }
}

or you can use the @EntityListener annotation on the class and place the event code in an external class.

I think you should use python wheels for distribution instead of egg now.

Wheels are the new standard of python distribution and are intended to replace eggs. Support is offered in pip >= 1.4 and setuptools >= 0.8.

this works for renaming the first key:

$a = ['catine' => 'cat', 'canine'  => 'dog'];
$tmpa['feline'] = $a['catine'];
unset($a['catine']);
$a = $tmpa + $a;

then, print_r($a) renders a repaired in-order array:

Array
(
    [feline] => cat
    [canine] => dog
)

this works for renaming an arbitrary key:

$a = ['canine'  => 'dog', 'catine' => 'cat', 'porcine' => 'pig']
$af = array_flip($a)
$af['cat'] = 'feline';
$a = array_flip($af)

print_r($a)

Array
(
    [canine] => dog
    [feline] => cat
    [porcine] => pig
)

a generalized function:

function renameKey($oldkey, $newkey, $array) {
    $val = $array[$oldkey];
    $tmp_A = array_flip($array);
    $tmp_A[$val] = $newkey;

    return array_flip($tmp_A);
}

If using the following HTML:

<button id="submit-button"></button>

Style can be applied through JS using the style object available on an HTMLElement.

To set height and width to 200px of the above example button, this would be the JS:

var myButton = document.getElementById('submit-button');
myButton.style.height = '200px';
myButton.style.width= '200px';

I believe with this method, you are not directly writing CSS (inline or external), but using JavaScript to programmatically alter CSS Declarations.

Here are the rules for how these functions work:

stringValue.CompareTo(otherStringValue)

1. null comes before a string
2. it uses CultureInfo.CurrentCulture.CompareInfo.Compare, which means it will use a culture-dependent comparison. This might mean that ß will compare equal to SS in Germany, or similar

stringValue.Equals(otherStringValue)

1. null is not considered equal to anything
2. unless you specify a StringComparison option, it will use what looks like a direct ordinal equality check, i.e. ß is not the same as SS, in any language or culture

stringValue == otherStringValue

1. Is not the same as stringValue.Equals().
2. The == operator calls the static Equals(string a, string b) method (which in turn goes to an internal EqualsHelper to do the comparison.
3. Calling .Equals() on a null string gets null reference exception, while on == does not.

Object.ReferenceEquals(stringValue, otherStringValue)

Just checks that references are the same, i.e. it isn't just two strings with the same contents, you're comparing a string object with itself.

Note that with the options above that use method calls, there are overloads with more options to specify how to compare.

My advice if you just want to check for equality is to make up your mind whether you want to use a culture-dependent comparison or not, and then use .CompareTo or .Equals, depending on the choice.

Try string.TrimEnd():

Something = Something.TrimEnd(',');

I had a similar problem.

As it turned out, I ran mvn clean package install.

Correct way is mvn clean install

Try

ps -ef | grep "KEYWORD" | awk '{print $2}'

That command should give you the PID of the processes with KEYWORD in them. In this instance, awk is returning what is in the 2nd column from the output.

exec is shelling to the operating system, and unless the OS has some special way of knowing how to execute a file, then it's going to default to treating it as a shell script or similar. In this case, it has no idea how to run your php file. If this script absolutely has to be executed from a shell, then either execute php passing the filename as a parameter, e.g

exec ('/usr/local/bin/php -f /opt/lampp/htdocs/.../name.php)') ;

or use the punct at the top of your php script

#!/usr/local/bin/php
<?php ... ?>

try with \w

This is my Solution for extend 100% height and 100% width in a html <td>

if you delete the first line in your code you can fix it ...

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
 "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

because this doctype does not permit in some files to use the 100% percent inside of <td>, but if you delete this line, the body fails expanding the background to 100% height and 100% width, so I found this DOCTYPE that solves the problem

<!DOCTYPE html PUBLIC "-//IETF//DTD HTML 2.0//EN">

this DOCTYPE let you extends the background in your body as 100% height and 100% width, and let you take all the 100% height and 100% width into the <td>

You can also check the .Any() method:

if (!YourResult.Any())

Just a note that .Any will still retrieve the records from the database; doing a .FirstOrDefault()/.Where() will be just as much overhead but you would then be able to catch the object(s) returned from the query

In C, it is a common idiom to zero out the memory for a struct using memset:

struct x myStruct;
memset(&myStruct, 0, sizeof(myStruct));

Technically speaking, I don't believe that this is portable because it assumes that the NULL pointer on a machine is represented by the integer value 0, but it's used widely because on most machines this is the case.

If you move from C to C++, be careful not to use this technique on every object. C++ only makes this legal on objects with no member functions and no inheritance.

you could just set outline: none; and border to a different color on focus.

Hope below helps!

PS C:\Users\aameer>$invoice = $object.'Invoice Month'
$invoice = "01-" + $invoice
[datetime]$Format_date =$invoice

Now type is converted. You can use method or can access any property.

Example :$Format_date.AddDays(5)

You need to wrap your input with component, and add containerElement property with value 'label' ...

<RaisedButton
   containerElement='label' // <-- Just add me!
   label='My Label'>
   <input type="file" />
</RaisedButton>

You can read more about it in this GitHub issue.

EDIT: Update 2019.

Check at the bottom answer from @galki

TLDR;

<input
  accept="image/*"
  className={classes.input}
  style={{ display: 'none' }}
  id="raised-button-file"
  multiple
  type="file"
/>
<label htmlFor="raised-button-file">
  <Button variant="raised" component="span" className={classes.button}>
    Upload
  </Button>
</label> 

you also can add this inline instead of config, just add it to the same file before you add your own disable stuff

/* eslint-env es6 */
/* eslint-disable no-console */

my case was disable a file and eslint-disable were not working for me alone

/* eslint-env es6 */
/* eslint-disable */

There may be one or multiple reasons if you are not able to connect to MAC OS X MySQL server with MySQL-workbench.

When you press 'test connection' you might see this error. This could be explained briefly if you go step by step through 'Configure server management..' On the basis of the red crosses you can filter out the real problem.

The most common problems are associated with the installation of MySQL-server. Few people either forget to install the server prior to installing MySQL-workbench. Some others would install a part of the product. Please check whether you have also installed all the 3 parts that comes with the MySQL-Server dmg(disk image) file which contains mysql-server package. Those 3 parts are: MySQL server, preference pane and startup item.

Note: If you haven't selected preference pane then you won't be able to start mysql server instance from the System preferences.

After you make sure that you have installed each item then you can check server instance of your native mysql-server. Open System preferences from dock and click MySQL. Then click Start MySQL Server to start the server instance. If the server instance is stopped, then MySQL-workbench won't be able to connect to the MySQL server.

If you are still facing issue, then you need to check the port of the connection which you are making. Default port is '3307' and NOT '3306'. You can check it with using the following command in mysql terminal:

SHOW GLOBAL VARIABLES LIKE 'PORT';

Please note that this process helps you to connect to the local instance. If you have to connect to a remote server, then you have to enter that specific IP and Port. Contact your server's administrator if you are facing the issue. As this question specifically states that the problem is related to connecting to the local instance, I am not writing checks that you may need to ensure.

>>> from operator import itemgetter
>>> data = [('abc', 121),('abc', 231),('abc', 148), ('abc',221)]
>>> sorted(data,key=itemgetter(1))
[('abc', 121), ('abc', 148), ('abc', 221), ('abc', 231)]

IMO using itemgetter is more readable in this case than the solution by @cheeken. It is also faster since almost all of the computation will be done on the c side (no pun intended) rather than through the use of lambda.

>python -m timeit -s "from operator import itemgetter; data = [('abc', 121),('abc', 231),('abc', 148), ('abc',221)]" "sorted(data,key=itemgetter(1))"
1000000 loops, best of 3: 1.22 usec per loop

>python -m timeit -s "data = [('abc', 121),('abc', 231),('abc', 148), ('abc',221)]" "sorted(data,key=lambda x: x[1])"
1000000 loops, best of 3: 1.4 usec per loop

Data Warehouse vs Database: A data warehouse is specially designed for data analytics, which involves reading large amounts of data to understand relationships and trends across the data. A database is used to capture and store data, such as recording details of a transaction.

Data Warehouse: Suitable workloads - Analytics, reporting, big data. Data source - Data collected and normalized from many sources. Data capture - Bulk write operations typically on a predetermined batch schedule. Data normalization - Denormalized schemas, such as the Star schema or Snowflake schema. Data storage - Optimized for simplicity of access and high-speed query. performance using columnar storage. Data access - Optimized to minimize I/O and maximize data throughput.

Transactional Database: Suitable workloads - Transaction processing. Data source - Data captured as-is from a single source, such as a transactional system. Data capture - Optimized for continuous write operations as new data is available to maximize transaction throughput. Data normalization - Highly normalized, static schemas. Data storage - Optimized for high throughout write operations to a single row-oriented physical block. Data access - High volumes of small read operations.

Use git checkout instead of git stash apply:

$ git checkout stash -- .
$ git commit

This will restore all the files in the current directory to their stashed version.

If there are changes to other files in the working directory that should be kept, here is a less heavy-handed alternative:

$ git merge --squash --strategy-option=theirs stash

If there are changes in the index, or the merge will touch files with local changes, git will refuse to merge. Individual files can be checked out from the stash using

$ git checkout stash -- <paths...>

or interactively with

$ git checkout -p stash

One thing that might not always be obvious to some is that a cross join with an empty table (or result set) results in empty table (M x N; hence M x 0 = 0)

A full outer join will always have rows unless both M and N are 0.

I was able to overcome this by using the "vh" metric with max-height on the .modal-body element. 70vh looked about right for my uses. Then set the overflow-y to auto so it only scrolls when needed.

.modal-body {
   overflow-y: auto;
   max-height: 70vh;
}

xargs -a your_file | sed 's/ /,/g'

This is a shorter way.

Using my library at rootbox, it is pretty easy. Check the required code below:

    //Pass true to <Shell>.start(...) call to run as superuser
    Shell shell = null;
    try {
            shell = Shell.start(true);
    } catch (IOException exception) {
            exception.printStackTrace();
    }
    if (shell == null)
            // We failed to execute su binary
            return;
    if (shell.isRoot()) {
            // Verified running as uid 0 (root), can continue with commands
            ...
    } else
            throw Exception("Unable to gain root access. Make sure you pressed Allow/Grant in superuser prompt.");

You can use Eclipse Collections factories:

Iterable<String> iterable = Arrays.asList("1", "2", "3");

MutableList<String> list = Lists.mutable.withAll(iterable);
MutableSet<String> set = Sets.mutable.withAll(iterable);
MutableSortedSet<String> sortedSet = SortedSets.mutable.withAll(iterable);
MutableBag<String> bag = Bags.mutable.withAll(iterable);
MutableSortedBag<String> sortedBag = SortedBags.mutable.withAll(iterable);

You can also convert the Iterable to a LazyIterable and use the converter methods or any of the other available APIs available.

Iterable<String> iterable = Arrays.asList("1", "2", "3");
LazyIterable<String> lazy = LazyIterate.adapt(iterable);

MutableList<String> list = lazy.toList();
MutableSet<String> set = lazy.toSet();
MutableSortedSet<String> sortedSet = lazy.toSortedSet();
MutableBag<String> bag = lazy.toBag();
MutableSortedBag<String> sortedBag = lazy.toSortedBag();

All of the above Mutable types extend java.util.Collection.

Note: I am a committer for Eclipse Collections.

If you happen to be using date in a MacOS environment, try this:

ST1:~ ejf$ date
Mon Feb 20 21:55:48 CST 2017
ST1:~ ejf$ date -v-1m +%m
01
ST1:~ ejf$ date -v+1m +%m
03

Also, I'd rather calculate the previous and next month on the first day of each month, this way you won't have issues with months ending the 30/31 or 28/29 (Feb/Feb leap year)

Instead of SELECT max(len(CR)) AS Max_Length_String FROM table1

Use

SELECT (CR) FROM table1

WHERE len(CR) = (SELECT max(len(CR)) FROM table1)

Parsing is the process of analyzing text made of a sequence of tokens to determine its grammatical structure with respect to a given (more or less) formal grammar.

The parser then builds a data structure based on the tokens. This data structure can then be used by a compiler, interpreter or translator to create an executable program or library.

If I gave you an english sentence, and asked you to break down the sentence into its parts of speech (nouns, verbs, etc.), you would be parsing the sentence.

That's the simplest explanation of parsing I can think of.

That said, parsing is a non-trivial computational problem. You have to start with simple examples, and work your way up to the more complex.

Both works. Instead of == you can write eq

One of the most important thing to remember when decorating a method with async is that at least there is one await operator inside the method. In your example, I would translate it as shown below using TaskCompletionSource.

private Task<int> DoWorkAsync()
{
    //create a task completion source
    //the type of the result value must be the same
    //as the type in the returning Task
    TaskCompletionSource<int> tcs = new TaskCompletionSource<int>();
    Task.Run(() =>
    {
        int result = 1 + 2;
        //set the result to TaskCompletionSource
        tcs.SetResult(result);
    });
    //return the Task
    return tcs.Task;
}

private async void DoWork()
{
    int result = await DoWorkAsync();
}

for i=1:length(list)
  elm = list(i);
  //do something with elm.

You can use a conditional expression:

x if x is not None else some_value

Example:

In [22]: x = None

In [23]: print x if x is not None else "foo"
foo

In [24]: x = "bar"

In [25]: print x if x is not None else "foo"
bar

PEP 8 defines that it is better to use the is operator when comparing singletons.

I found @AgileZebra's answer (plus @starfry's comment) the most useful, but it sets heads to a scalar. An array is probably more useful:

heads=( "${@:1:$(($# - 1))}" )
tail=${@:${#@}}

Note that this is bash-only.

Specify /D to change the drive also.

CD /D %root%

If you want to change the range to [0, 1], make sure the output data type is float.

image = cv2.imread("lenacolor512.tiff", cv2.IMREAD_COLOR)  # uint8 image
norm_image = cv2.normalize(image, None, alpha=0, beta=1, norm_type=cv2.NORM_MINMAX, dtype=cv2.CV_32F)

document.cookie = "cookiename=Some Name; path=/";

This will do

You can prefix the function declaration with extern “C” keyword, e.g.

extern “C” int Mycppfunction()

{

// Code goes here

return 0;

}

For more examples you can search more on Google about “extern” keyword. You need to do few more things, but it's not difficult you'll get lots of examples from Google.

I meet the same issue on a Windows installed .NET Framework 4.0.
And I Solved this issue by installing .NET Framework 4.6.2.
Or you may download the newest package to have a try.

I think the simplest way might be:

values.reduce(function(a, b){return a+b;})

Here are some more console logging "pro tips":

console.table

var animals = [
    { animal: 'Horse', name: 'Henry', age: 43 },
    { animal: 'Dog', name: 'Fred', age: 13 },
    { animal: 'Cat', name: 'Frodo', age: 18 }
];

console.table(animals);

console.trace

Shows you the call stack for leading up to the console.

You can even customise your consoles to make them stand out

console.todo = function(msg) {
    console.log(‘ % c % s % s % s‘, ‘color: yellow; background - color: black;’, ‘–‘, msg, ‘–‘);
}

console.important = function(msg) {
    console.log(‘ % c % s % s % s’, ‘color: brown; font - weight: bold; text - decoration: underline;’, ‘–‘, msg, ‘–‘);
}

console.todo(“This is something that’ s need to be fixed”);
console.important(‘This is an important message’);

If you really want to level up don't limit your self to the console statement.

Here is a great post on how you can integrate a chrome debugger right into your code editor!

Moving Dylan's comment into a full-blown answer because TOO USEFUL:

docker run --rm -v /var/run/docker.sock:/var/run/docker.sock assaflavie/runlike YOUR-CONTAINER

What does it do? Runs https://github.com/lavie/runlike inside a container, gets you the complete docker run command, then removes the container for you.

There is no hard and fast rule.

Here are some rules to make code thread safe in .NET and why these are not good rules:

1. Function and all functions it calls must be pure (no side effects) and use local variables. Although this will make your code thread-safe, there is also very little amount of interesting things you can do with this restriction in .NET.
2. Every function that operates on a common object must lock on a common thing. All locks must be done in same order. This will make the code thread safe, but it will be incredibly slow, and you might as well not use multiple threads.
3. ...

There is no rule that makes the code thread safe, the only thing you can do is make sure that your code will work no matter how many times is it being actively executed, each thread can be interrupted at any point, with each thread being in its own state/location, and this for each function (static or otherwise) that is accessing common objects.

Seems you have installed express in root directory.Copy path of package.json and delete package json file and node_modules folder.

I solved this, without having to completely reinstall Visual Studio 2013.

For those who may come across this in the future, the following steps worked for me:

1. Run the ISO (or vs_professional.exe).

2. If you get the error below, you need to update the Windows Registry to trick the installer into thinking you still have the base version. If you don't get this error, skip to step 3

   • Click the link for 'examine the log file' and look near the bottom of the log, for this line:

   • open regedit.exe and do an Edit > Find... for that GUID. In my case it was {6dff50d0-3bc3-4a92-b724-bf6d6a99de4f}. This was found in:

     HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall{6dff50d0-3bc3-4a92-b724-bf6d6a99de4f}

   • Edit the BundleVersion value and change it to a lower version. I changed mine from 12.0.21005.13 to 12.0.21000.13:

   • Exit the registry

3. Run the ISO (or vs_professional.exe) again. If it has a repair button like the image below, you can skip to step 4.

   

   • Otherwise you have to let the installer fix the registry. I did this by "installing" at least one feature, even though I think I already had all features (they were not detected). This took about 20 minutes.

4. Run the ISO (or vs_professional.exe) again. This time repair should be visible.

5. Click Repair and let it update your installation and apply its embedded license key. This took about 20 minutes.

Now when you run Visual Studio 2013, it should indicate that a license key was applied, under Help > Register Product:

Hope this helps somebody in the future!

The second one would be more efficient as it just has one predicate to evaluate against each item in the collection where as in the first one, it's applying the first predicate to all items first and the result (which is narrowed down at this point) is used for the second predicate and so on. The results get narrowed down every pass but still it involves multiple passes.

Also the chaining (first method) will work only if you are ANDing your predicates. Something like this x.Age == 10 || x.Fat == true will not work with your first method.

First of all, since Spring doesn't do persistence itself, it cannot specify what readOnly should exactly mean. This attribute is only a hint to the provider, the behavior depends on, in this case, Hibernate.

If you specify readOnly as true, the flush mode will be set as FlushMode.NEVER in the current Hibernate Session preventing the session from committing the transaction.

Furthermore, setReadOnly(true) will be called on the JDBC Connection, which is also a hint to the underlying database. If your database supports it (most likely it does), this has basically the same effect as FlushMode.NEVER, but it's stronger since you cannot even flush manually.

Now let's see how transaction propagation works.

If you don't explicitly set readOnly to true, you will have read/write transactions. Depending on the transaction attributes (like REQUIRES_NEW), sometimes your transaction is suspended at some point, a new one is started and eventually committed, and after that the first transaction is resumed.

OK, we're almost there. Let's see what brings readOnly into this scenario.

If a method in a read/write transaction calls a method that requires a readOnly transaction, the first one should be suspended, because otherwise a flush/commit would happen at the end of the second method.

Conversely, if you call a method from within a readOnly transaction that requires read/write, again, the first one will be suspended, since it cannot be flushed/committed, and the second method needs that.

In the readOnly-to-readOnly, and the read/write-to-read/write cases the outer transaction doesn't need to be suspended (unless you specify propagation otherwise, obviously).

the issue happened with me, I resolved by removing the scope tag only and built successfully.

set -x is fine, but if you do something like:

set -x;
command;
set +x;

it would result in printing

+ command
+ set +x;

You can use a subshell to prevent that such as:

(set -x; command)

which would just print the command.

I just want to add a note to the answer by @Snicolas. The following steps can be used to check stop service with/without calling onDestroy().

1. onDestroy() called: Go to Settings -> Application -> Running Services -> Select and stop your service.

2. onDestroy() not Called: Go to Settings -> Application -> Manage Applications -> Select and "Force Stop" your application in which your service is running. However, as your application is stopped here, so definitely the service instances will also be stopped.

Finally, I would like to mention that the approach mentioned there using a static variable in singleton class is working for me.

To convert seconds time stamp to millisecond time stamp. You could use the TimeUnit API and neat like this.

long milliSecondTimeStamp = MILLISECONDS.convert(secondsTimeStamp, SECONDS)

  $.ajax({
        url: '//freegeoip.net/json/',
        type: 'POST',
        dataType: 'jsonp',
        success: function(location) {
            alert(location.ip);
        }
    });

This code will work https sites too

You must set proxy server for gradle at some time, you can try to change the proxy server ip address in gradle.properties which is under .gradle document

I have tried in many ways. The only way that worked for me was:

The Yush0 CSS solution:

#yourTable{
    table-layout: fixed !important;
    word-wrap:break-word;
}

Together with Roy Jackson HTML Solution:

    <th style='width: 5%;'>ProjectId</th>
    <th style='width: 15%;'>Title</th>
    <th style='width: 40%;'>Abstract</th>
    <th style='width: 20%;'>Keywords</th>
    <th style='width: 10%;'>PaperName</th>
    <th style='width: 10%;'>PaperURL</th>
</tr>

A web server runs the HTTP protocol to serve web pages. An application server can (but doesn't always) run on a web server to execute program logic, the results of which can then be delivered by the web server. That's one example of a web server/application server scenario.

A good example in the Microsoft world is the Internet Information Server / SharePoint Server relationship. IIS is a web server; SharePoint is an application server. SharePoint sits "on top" of IIS, executes specific logic, and serves the results via IIS.

In the Java world, there's a similar scenario with Apache and Tomcat, for example.

I'm not sure that Java has infinity for every numerical type but for some numerical data types the answer is positive:

Float.POSITIVE_INFINITY
Float.NEGATIVE_INFINITY

or

Double.POSITIVE_INFINITY
Double.NEGATIVE_INFINITY

Also you may find useful the following article which represents some mathematical operations involving +/- infinity: Java Floating-Point Number Intricacies.

In case you'd like to do it with async:

const request = async <T>(param1: string, param2: number) => {
  const res = await func();
  return res.response() as T;
}

And a more complex pattern, in case you'd like to wrap your function inside a generic counterpart, such as memoization (Example uses fast-memoize):

const request = memoize(
  async <T>(
    url: string,
    token?: string
  ) => {
    // Perform your code here
  }
);

See how you define the generic after the memoizing function.

Sub SelectAllCellsInSheet(SheetName As String)
    lastCol = Sheets(SheetName).Range("a1").End(xlToRight).Column
    Lastrow = Sheets(SheetName).Cells(1, 1).End(xlDown).Row
    Sheets(SheetName).Range("A2", Sheets(SheetName).Cells(Lastrow, lastCol)).Select
End Sub

To use with ActiveSheet:

Call SelectAllCellsInSheet(ActiveSheet.Name)

String dataIWant = mydata.replaceFirst(".*'(.*?)'.*", "$1");

If you do something like this:

size will be taken from "some large text".Length

This can be problematic when it's an output parameter, you get back no more characters then you put as input.

Had the same problem with Windows 10 when turned on all IIS windows features. Switched to Windows 8.1 and got problem again. The root was in web site name "http://MySite.local" (not related to OS version).

And solution is simple

• Edit hosts file in %SystemRoot%\System32\drivers\etc\

• Add line with ip binding: 127.0.0.1 MySite.local

The appropriate way to read text files in Cocoa/Objective-C is documented in Apple's String programming guide. The section for reading and writing files should be just what you're after. PS: What's a "line"? Two sections of a string separated by "\n"? Or "\r"? Or "\r\n"? Or maybe you're actually after paragraphs? The previously mentioned guide also includes a section on splitting a string into lines or paragraphs. (This section is called "Paragraphs and Line Breaks", and is linked to in the left-hand-side menu of the page I pointed to above. Unfortunately this site doesn't allow me to post more than one URL as I'm not a trustworthy user yet.)

To paraphrase Knuth: premature optimisation is the root of all evil. Don't simply assume that "reading the whole file into memory" is slow. Have you benchmarked it? Do you know that it actually reads the whole file into memory? Maybe it simply returns a proxy object and keeps reading behind the scenes as you consume the string? (Disclaimer: I have no idea if NSString actually does this. It conceivably could.) The point is: first go with the documented way of doing things. Then, if benchmarks show that this doesn't have the performance you desire, optimise.

Here is one that works better for me (LINQPad version):

DateTime d;
DateTime.TryParseExact(
    "2010-08-20T15:00:00Z",
    @"yyyy-MM-dd\THH:mm:ss\Z",
    CultureInfo.InvariantCulture,
    DateTimeStyles.AssumeUniversal, 
    out d);
d.ToString()

produces

true

String literals

Escaping single quotes ' by doubling them up -> '' is the standard way and works of course:

'user's log'     -- incorrect syntax (unbalanced quote)
'user''s log'

In old versions or if you still run with standard_conforming_strings = off or, generally, if you prepend your string with E to declare Posix escape string syntax, you can also escape with the backslash \:

E'user\'s log'

Backslash itself is escaped with another backslash. But that's generally not preferable.
If you have to deal with many single quotes or multiple layers of escaping, you can avoid quoting hell in PostgreSQL with dollar-quoted strings:

'escape '' with '''''
$$escape ' with ''$$

To further avoid confusion among dollar-quotes, add a unique token to each pair:

$token$escape ' with ''$token$

Which can be nested any number of levels:

$token2$Inner string: $token1$escape ' with ''$token1$ is nested$token2$

Pay attention if the $ character should have special meaning in your client software. You may have to escape it in addition. This is not the case with standard PostgreSQL clients like psql or pgAdmin.

That is all very useful for writing plpgsql functions or ad-hoc SQL commands. It cannot alleviate the need to use prepared statements or some other method to safeguard against SQL injection in your application when user input is possible, though. @Craig's answer has more on that. More details:

• SQL injection in Postgres functions vs prepared queries

Values inside Postgres

When dealing with values inside the database, there are a couple of useful functions to quote strings properly:

• quote_literal() or quote_nullable() - the latter outputs the string NULL for null input. (There is also quote_ident() to double-quote strings where needed to get valid SQL identifiers.)
• format() with the format specifier %L is equivalent to quote_nullable().
  Like: format('%L', string_var)
• concat() or concat_ws() are typically no good for this purpose as those do not escape nested single quotes and backslashes.

From Hadoop page,

start-all.sh 

This will startup a Namenode, Datanode, Jobtracker and a Tasktracker on your machine.

start-dfs.sh

This will bring up HDFS with the Namenode running on the machine you ran the command on. On such a machine you would need start-mapred.sh to separately start the job tracker

start-all.sh/stop-all.sh has to be run on the master node

You would use start-all.sh on a single node cluster (i.e. where you would have all the services on the same node.The namenode is also the datanode and is the master node).

In multi-node setup,

You will use start-all.sh on the master node and would start what is necessary on the slaves as well.

Alternatively,

Use start-dfs.sh on the node you want the Namenode to run on. This will bring up HDFS with the Namenode running on the machine you ran the command on and Datanodes on the machines listed in the slaves file.

Use start-mapred.sh on the machine you plan to run the Jobtracker on. This will bring up the Map/Reduce cluster with Jobtracker running on the machine you ran the command on and Tasktrackers running on machines listed in the slaves file.

hadoop-daemon.sh as stated by Tariq is used on each individual node. The master node will not start the services on the slaves.In a single node setup this will act same as start-all.sh.In a multi-node setup you will have to access each node (master as well as slaves) and execute on each of them.

Have a look at this start-all.sh it call config followed by dfs and mapred

You can do this in your code:

final ListView lv = (ListView) convertView.findViewById(R.id.list_view);

for (int i = 0; i < lv.getChildCount(); i++) {
    ((TextView)lv.getChildAt(i)).setTextColor(getResources().getColor(R.color.black));
}

Hint 1: read the description of linked lists at http://en.wikipedia.org/wiki/Linked_list

Hint 2: the Java implementation of LinkedList is a doubly linked list. Yours is a singly linked list. The algorithms don't directly apply.

Also:

... but creating [a linked list class] from scratch makes no sense whatsoever.

It depends on what the required outcome of the work is. If the goal is to produce code that meets certain functional / non-functional requirements, then you are right. If the real goal is for you to learn how to program / design APIs / implement non-trivial data structures, then the utility of the final product is almost entirely irrelevant.

And thus magically we have a linked list

What you actually have there is a open data type, that could be used to build a (sort of) list. But that is not what your teacher wants. And it certainly would not be considered to be a useful list abstraction. A useful abstraction would include:

• methods to do the things that programmers don't want to have to repeat over and over again, and

• an abstraction layer that stops programmers "breaking" the list; e.g. by accidentally creating a cycle, or accidentally stitching a sublist in two lists to create an inverted tree.

When your program has more open descriptors than the open files ulimit (ulimit -a will list this), the kernel will refuse to open any more file descriptors. Make sure you don't have any file descriptor leaks - for example, by running it for a while, then stopping and seeing if any extra fds are still open when it's idle - and if it's still a problem, change the nofile ulimit for your user in /etc/security/limits.conf

In the detached window (Tool Options), the name of the view (Paintbrush) is a grab-bar.

Put your cursor over the grab-bar, click and drag it to the dock area in the main window in order to reattach it to the main window.

In controller:

function innerItem($scope, $element){
    var jQueryInnerItem = $($element); 
}

Change your code from:

render() {
    return (
      <ol>
        {this.props.results.map((result) => (
          <li>{result.text}</li>
        ))}
      </ol>
    );
}

To:

render() {
    return (
      <ol>
        {this.props.results.map((result) => (
          <li key={result.id}>{result.text}</li>
        ))}
      </ol>
    );
}

Then solved.

You can use the regex

(\s)\1

and

replace it with $1.

Java code:

str = str.replaceAll("(\\s)\\1","$1");

If the input is "foo\t\tbar " you'll get "foo\tbar " as output
But if the input is "foo\t bar" it will remain unchanged because it does not have any consecutive whitespace characters.

If you treat all the whitespace characters(space, vertical tab, horizontal tab, carriage return, form feed, new line) as space then you can use the following regex to replace any number of consecutive white space with a single space:

str = str.replaceAll("\\s+"," ");

But if you want to replace two consecutive white space with a single space you should do:

str = str.replaceAll("\\s{2}"," ");

This is what I am using as of now:

nnoremap <silent> <Leader>= :exe "resize " . (winheight(0) * 3/2)<CR>
nnoremap <silent> <Leader>- :exe "resize " . (winheight(0) * 2/3)<CR>
nnoremap <silent> <Leader>0 :exe "vertical resize " . (winwidth(0) * 3/2)<CR>
nnoremap <silent> <Leader>9 :exe "vertical resize " . (winwidth(0) * 2/3)<CR>

This answer has long been answered, but I thought I would share my Decorator class which makes writing new decorators easy and compact.

from abc import ABCMeta, abstractclassmethod

class Decorator(metaclass=ABCMeta):
    """ Acts as a base class for all decorators """

    def __init__(self):
        self.method = None

    def __call__(self, method):
        self.method = method
        return self.call

    @abstractclassmethod
    def call(self, *args, **kwargs):
        return self.method(*args, **kwargs)

For one I think this makes the behavior of decorators very clear, but it also makes it easy to define new decorators very concisely. For the example listed above, you could then solve it as:

class MakeBold(Decorator):
    def call():
        return "<b>" + self.method() + "</b>"

class MakeItalic(Decorator):
    def call():
        return "<i>" + self.method() + "</i>"

@MakeBold()
@MakeItalic()
def say():
   return "Hello"

You could also use it to do more complex tasks, like for instance a decorator which automatically makes the function get applied recursively to all arguments in an iterator:

class ApplyRecursive(Decorator):
    def __init__(self, *types):
        super().__init__()
        if not len(types):
            types = (dict, list, tuple, set)
        self._types = types

    def call(self, arg):
        if dict in self._types and isinstance(arg, dict):
            return {key: self.call(value) for key, value in arg.items()}

        if set in self._types and isinstance(arg, set):
            return set(self.call(value) for value in arg)

        if tuple in self._types and isinstance(arg, tuple):
            return tuple(self.call(value) for value in arg)

        if list in self._types and isinstance(arg, list):
            return list(self.call(value) for value in arg)

        return self.method(arg)


@ApplyRecursive(tuple, set, dict)
def double(arg):
    return 2*arg

print(double(1))
print(double({'a': 1, 'b': 2}))
print(double({1, 2, 3}))
print(double((1, 2, 3, 4)))
print(double([1, 2, 3, 4, 5]))

Which prints:

2
{'a': 2, 'b': 4}
{2, 4, 6}
(2, 4, 6, 8)
[1, 2, 3, 4, 5, 1, 2, 3, 4, 5]

Notice that this example didn't include the list type in the instantiation of the decorator, so in the final print statement the method gets applied to the list itself, not the elements of the list.

It is recommended that you create a file named setenv.bat and place it in the Tomcat bin directory. With this file (which is run by the catalina.bat and catalina.sh scripts), you can change the following Tomcat environment settings with the JAVA_OPTS variable:

You can set the minimum and maximum memory heap size with the

JVM -Xms and -Xmx parameters.

The best limits depend on many conditions, such as transformations that Integrator ETL should execute. For Information Discovery transformations, a maximum of 1 GB is recommended. For example, to set the minimum heap size to 128 MB and the maximum heap size to 1024 MB, use

JAVA_OPTS=-Xms128m -Xmx1024m        

You should set the maximum limit of the PermGen (Permanent Generation) memory space to a size larger than the default. The default of 64 MB is not enough for enterprise applications. A suitable memory limit depends on various criteria, but 256 MB would make a good choice in most cases. If the PermGen space maximum is too low, OutOfMemoryError: PermGen space errors may occur. You can set the PermGen maximum limit with the following JVM parameter

    -XX:MaxPermSize=256m

For performance reasons, it is recommended that the application is run in Server mode. Apache Tomcat does not run in Server mode by default. You can set the Server mode by using the JVM -server parameter. You can set the JVM parameter in the JAVA_OPTS variable in the environment variable in the setenv file.

The following is an example of a setenv.bat file:

set "JAVA_OPTS=%JAVA_OPTS% -Xms128m -Xmx1024m -XX:MaxPermSize=256m -server"

To account for leading and trailing whitespace, you probably want to use normalize-space()

//div[contains(@class, 'Caption') and normalize-space(.)='Model saved']

and

//div[@id='alertLabel' and normalize-space(.)='Save to server successful']

Note that //div[contains(@class, 'Caption') and normalize-space(.//text())='Model saved'] also works.

you can do top level await since typescript 3.8
https://www.typescriptlang.org/docs/handbook/release-notes/typescript-3-8.html#-top-level-await
From the post:
This is because previously in JavaScript (along with most other languages with a similar feature), await was only allowed within the body of an async function. However, with top-level await, we can use await at the top level of a module.

const response = await fetch("...");
const greeting = await response.text();
console.log(greeting);

// Make sure we're a module
export {};

Note there’s a subtlety: top-level await only works at the top level of a module, and files are only considered modules when TypeScript finds an import or an export. In some basic cases, you might need to write out export {} as some boilerplate to make sure of this.

Top level await may not work in all environments where you might expect at this point. Currently, you can only use top level await when the target compiler option is es2017 or above, and module is esnext or system. Support within several environments and bundlers may be limited or may require enabling experimental support.

Since IOS 9.0 use UIAlertController:

UIAlertController* alert = [UIAlertController alertControllerWithTitle:@"My Alert"
                                                           message:@"This is an alert."
                                                          preferredStyle:UIAlertControllerStyleAlert];

UIAlertAction* defaultAction = [UIAlertAction actionWithTitle:@"OK" style:UIAlertActionStyleDefault
                                                  handler:^(UIAlertAction * action) {
                    //use alert.textFields[0].text
                                                       }];
UIAlertAction* cancelAction = [UIAlertAction actionWithTitle:@"Cancel" style:UIAlertActionStyleDefault
                                                      handler:^(UIAlertAction * action) {
                                                          //cancel action
                                                      }];
[alert addTextFieldWithConfigurationHandler:^(UITextField * _Nonnull textField) {
    // A block for configuring the text field prior to displaying the alert
}];
[alert addAction:defaultAction];
[alert addAction:cancelAction];
[self presentViewController:alert animated:YES completion:nil];

As karim79 mentioned, the first is the most concise. However I could argue that the second is more understandable as it is not obvious/known to some Javascript/jQuery programmers that non-zero/false values are evaluated to true in if-statements. And because of that, the third method is incorrect.

Having just encountered this on Arch Linux 4.13.3, I solved the issue by simply reinstalling semver:

pacman -S semver

Both methods do the same functionally - they compare values.
As is written on MSDN:

• About String.Equals method - Determines whether this instance and another specified String object have the same value. (http://msdn.microsoft.com/en-us/library/858x0yyx.aspx)
• About == - Although string is a reference type, the equality operators (== and !=) are defined to compare the values of string objects, not references. This makes testing for string equality more intuitive. (http://msdn.microsoft.com/en-en/library/362314fe.aspx)

But if one of your string instances is null, these methods are working differently:

string x = null;
string y = "qq";
if (x == y) // returns false
    MessageBox.Show("true");
else
    MessageBox.Show("false");

if (x.Equals(y)) // returns System.NullReferenceException: Object reference not set to an instance of an object. - because x is null !!!
    MessageBox.Show("true");
else
    MessageBox.Show("false");

I think this is a very useful question with good answer. Just to add my two cents from the MSDN Create a Login page:

A login is a security principal, or an entity that can be authenticated by a secure system. Users need a login to connect to SQL Server. You can create a login based on a Windows principal (such as a domain user or a Windows domain group) or you can create a login that is not based on a Windows principal (such as an SQL Server login).

Note:
To use SQL Server Authentication, the Database Engine must use mixed mode authentication. For more information, see Choose an Authentication Mode.

As a security principal, permissions can be granted to logins. The scope of a login is the whole Database Engine. To connect to a specific database on the instance of SQL Server, a login must be mapped to a database user. Permissions inside the database are granted and denied to the database user, not the login. Permissions that have the scope of the whole instance of SQL Server (for example, the CREATE ENDPOINT permission) can be granted to a login.

Looks like you forgot adding correct headers to your get request (ask the REST API developer or you specific API description):

HttpURLConnection connection = (HttpURLConnection)url.openConnection();
connection.header("Accept", "application/xml")
connection.setRequestMethod("GET");
connection.connect();

or

connection.header("Accept", "application/xml;version=1")

Another way would be to use lftp:

lftp sftp://user:password@host  -e "put local-file.name; bye"

The disadvantage of this method is that other users on the computer can read the password from tools like ps and that the password can become part of your shell history.

A more secure alternative which is available since LFTP 4.5.0 is setting the LFTP_PASSWORDenvironment variable and executing lftp with --env-password. Here's a full example:

LFTP_PASSWORD="just_an_example"
lftp --env-password sftp://user@host  -e "put local-file.name; bye"

LFTP also includes a cool mirroring feature (can include delete after confirmed transfer --Remove-source-files):

lftp -e 'mirror -R /local/log/path/ /remote/path/' --env-password -u user sftp.foo.com

Simple way to detect scroll up/down on android listview

@Override
public void onScroll(AbsListView view, int firstVisibleItem, int visibleItemCount, int totalItemCount){
  if(prevVisibleItem != firstVisibleItem){
    if(prevVisibleItem < firstVisibleItem)
      //ScrollDown
    else
      //ScrollUp

  prevVisibleItem = firstVisibleItem;
}

dont forget

yourListView.setOnScrollListener(yourScrollListener);

This one works for me:

index.php

    <?php
       if(isset($_GET['action']))
              {
                 //your code
                 echo 'Welcome';
              }
    ?>


    <form id="frm" method="post"  action="?action" >
    <input type="submit" value="Submit" id="submit" />
    </form>

better to used refresh migrate

You may rollback & re-migrate a limited number of migrations by providing the step option to the refresh command. For example, the following command will rollback & re-migrate the last two migrations:

php artisan migrate:refresh --step=2

otherwise used rollback migrate

You may rollback a limited number of migrations by providing the step option to the rollback command. For example, the following command will rollback the last three migrations:

php artisan migrate:rollback --step=3

Fix could be as simple as clicking run/skip all breakpoints. Worked for me.

This will tell you what line is the problem.

import csv

lines = []
with open('output.txt','r') as f:
    for line in f.readlines():
        lines.append(line[:-1])

with open('corrected.csv','w') as correct:
    writer = csv.writer(correct, dialect = 'excel')
    with open('input.csv', 'r') as mycsv:
        reader = csv.reader(mycsv)
        try:
            for i, row in enumerate(reader):
                if row[0] not in lines:
                   writer.writerow(row)
        except csv.Error:
            print('csv choked on line %s' % (i+1))
            raise

Perhaps this from daniweb would be helpful:

I'm getting this error when reading from a csv file: "Runtime Error! line contains NULL byte". Any idea about the root cause of this error?

...

Ok, I got it and thought I'd post the solution. Simply yet caused me grief... Used file was saved in a .xls format instead of a .csv Didn't catch this because the file name itself had the .csv extension while the type was still .xls

Add click listener for item view in .onBindViewHolder() of your RecyclerView's adapter. get currently selected position and change color by .setBackground() for previously selected and current item

Supposing you desire the following features:

1. Source file behaves properly in your debugger (filename shows in stack, etc)
2. __name__ == '__main__' is True so scripts behave properly as scripts.

The exec(open('foo.py').read()) fails feature 1 The import foo strategy fails feature 2

To get both, you need this:

    source = open(filename).read()
    code = compile(source, filename, 'exec')
    exec(code)

Method 1:

If the method DoSomethingBeta was static you need only call:

Beta.DoSomethingBeta();

Method 2:

If Alpha extends from Beta you could call DoSomethingBeta() directly.

public class Alpha extends Beta{
     public void DoSomethingAlpha() {
          DoSomethingBeta();  //?
     }
}

Method 3:

Alternatively you need to have access to an instance of Beta to call the methods from it.

public class Alpha {
     public void DoSomethingAlpha() {
          Beta cbeta = new Beta();
          cbeta.DoSomethingBeta();  //?
     }
}

Incidentally is this homework?

If you're willing to run X applications as well - use xpra together with "screen".

If you have a strong suspicion that the DOUBLE is actually a LONG, and you want to

1) get a handle on its EXACT value as a LONG

2) throw an error when its not a LONG

you can try something like this:

public class NumberUtils {

    /**
    * Convert a {@link Double} to a {@link Long}.
    * Method is for {@link Double}s that are actually {@link Long}s and we just
    * want to get a handle on it as one.
    */
    public static long getDoubleAsLong(double specifiedNumber) {
        Assert.isTrue(NumberUtils.isWhole(specifiedNumber));
        Assert.isTrue(specifiedNumber <= Long.MAX_VALUE && specifiedNumber >= Long.MIN_VALUE);
        // we already know its whole and in the Long range
        return Double.valueOf(specifiedNumber).longValue();
    }

    public static boolean isWhole(double specifiedNumber) {
        // http://stackoverflow.com/questions/15963895/how-to-check-if-a-double-value-has-no-decimal-part
        return (specifiedNumber % 1 == 0);
    }
}

Long is a subset of Double, so you might get some strange results if you unknowingly try to convert a Double that is outside of Long's range:

@Test
public void test() throws Exception {
    // Confirm that LONG is a subset of DOUBLE, so numbers outside of the range can be problematic
    Assert.isTrue(Long.MAX_VALUE < Double.MAX_VALUE);
    Assert.isTrue(Long.MIN_VALUE > -Double.MAX_VALUE); // Not Double.MIN_VALUE => read the Javadocs, Double.MIN_VALUE is the smallest POSITIVE double, not the bottom of the range of values that Double can possible be

    // Double.longValue() failure due to being out of range => results are the same even though I minus ten
    System.out.println("Double.valueOf(Double.MAX_VALUE).longValue(): " + Double.valueOf(Double.MAX_VALUE).longValue());
    System.out.println("Double.valueOf(Double.MAX_VALUE - 10).longValue(): " + Double.valueOf(Double.MAX_VALUE - 10).longValue());

    // casting failure due to being out of range => results are the same even though I minus ten
    System.out.println("(long) Double.valueOf(Double.MAX_VALUE): " + (long) Double.valueOf(Double.MAX_VALUE).doubleValue());
    System.out.println("(long) Double.valueOf(Double.MAX_VALUE - 10).longValue(): " + (long) Double.valueOf(Double.MAX_VALUE - 10).doubleValue());
}

This is probably not the main reason why the create_all() method call doesn't work for people, but for me, the cobbled together instructions from various tutorials have it such that I was creating my db in a request context, meaning I have something like:

# lib/db.py
from flask import g, current_app
from flask_sqlalchemy import SQLAlchemy

def get_db():
  if 'db' not in g:
    g.db = SQLAlchemy(current_app)
  return g.db

I also have a separate cli command that also does the create_all:

# tasks/db.py
from lib.db import get_db

@current_app.cli.command('init-db')
def init_db():
  db = get_db()
  db.create_all()

I also am using a application factory.

When the cli command is run, a new app context is used, which means a new db is used. Furthermore, in this world, an import model in the init_db method does not do anything, because it may be that your model file was already loaded(and associated with a separate db).

The fix that I came around to was to make sure that the db was a single global reference:

# lib/db.py
from flask import g, current_app
from flask_sqlalchemy import SQLAlchemy

db = None
def get_db():
  global db
  if not db:
    db = SQLAlchemy(current_app)
  return db

I have not dug deep enough into flask, sqlalchemy, or flask-sqlalchemy to understand if this means that requests to the db from multiple threads are safe, but if you're reading this you're likely stuck in the baby stages of understanding these concepts too.

1. Set a breakpoint as usual
2. Right click on the breakpoint and select Condition
3. You'll see a dialog that says "Breakpoint Condition"
4. Put a condition in the field e.g. "i==5"

The breakpoint will only get hit when i is 5.

You can use an HTTP Handler (.ashx) to download a file, like this:

DownloadFile.ashx:

public class DownloadFile : IHttpHandler 
{
    public void ProcessRequest(HttpContext context)
    {   
        System.Web.HttpResponse response = System.Web.HttpContext.Current.Response;
        response.ClearContent();
        response.Clear();
        response.ContentType = "text/plain";
        response.AddHeader("Content-Disposition", 
                           "attachment; filename=" + fileName + ";");
        response.TransmitFile(Server.MapPath("FileDownload.csv"));
        response.Flush();    
        response.End();
    }

    public bool IsReusable
    {
        get
        {
            return false;
        }
    }
}

Then you can call the HTTP Handler from the button click event handler, like this:

Markup:

<asp:Button ID="btnDownload" runat="server" Text="Download File" 
            OnClick="btnDownload_Click"/>

Code-Behind:

protected void btnDownload_Click(object sender, EventArgs e)
{
    Response.Redirect("PathToHttpHandler/DownloadFile.ashx");
}

Passing a parameter to the HTTP Handler:

You can simply append a query string variable to the Response.Redirect(), like this:

Response.Redirect("PathToHttpHandler/DownloadFile.ashx?yourVariable=yourValue");

Then in the actual handler code you can use the Request object in the HttpContext to grab the query string variable value, like this:

System.Web.HttpRequest request = System.Web.HttpContext.Current.Request;
string yourVariableValue = request.QueryString["yourVariable"];

// Use the yourVariableValue here

Note - it is common to pass a filename as a query string parameter to suggest to the user what the file actually is, in which case they can override that name value with Save As...

Try this:

if (!emailRegistration.matches("[a-zA-Z0-9._-]+@[a-z]+\.[a-z]+")) {
 editTextEmail.setError("Invalid Email Address");
}

Hope it is useful for someone.

PHP's getimagesize() returns an array of data. The first two items in the array are the two items you're interested in: the width and height. To get these, you would simply request the first two indexes in the returned array:

var $imagedata = getimagesize("someimage.jpg");

print "Image width  is: " . $imagedata[0];
print "Image height is: " . $imagedata[1];

For further information, see the documentation.

I knew that i am too late for this answer, but i hope this will help to other who are facing and who will face.

As you have written h_url is global var like var = h_url; so you can use that variable anywhere in your file.

• h_url=document.getElementById("u").value; Here h_url contain value of your search box text value whatever user has typed.

• document.getElementById("u"); This is the identifier of your form field with some specific ID.

• Your Search Field without id

  <input type="text" class="searchbox1" name="search" placeholder="Search for Brand, Store or an Item..." value="text" />

• Alter Search Field with id

  <input id="u" type="text" class="searchbox1" name="search" placeholder="Search for Brand, Store or an Item..." value="text" />

• When you click on submit that will try to fetch value from document.getElementById("u").value; which is syntactically right but you haven't define id so that will return null.

• So, Just make sure while you use form fields first define that ID and do other task letter.

I hope this helps you and never get Cannot set property 'value' of null Error.

except:

accepts all exceptions, whereas

except Exception as e:

only accepts exceptions that you're meant to catch.

Here's an example of one that you're not meant to catch:

>>> try:
...     input()
... except:
...     pass
... 
>>> try:
...     input()
... except Exception as e:
...     pass
... 
Traceback (most recent call last):
  File "<stdin>", line 2, in <module>
KeyboardInterrupt

The first one silenced the KeyboardInterrupt!

Here's a quick list:

issubclass(BaseException, BaseException)
#>>> True
issubclass(BaseException, Exception)
#>>> False


issubclass(KeyboardInterrupt, BaseException)
#>>> True
issubclass(KeyboardInterrupt, Exception)
#>>> False


issubclass(SystemExit, BaseException)
#>>> True
issubclass(SystemExit, Exception)
#>>> False

If you want to catch any of those, it's best to do

except BaseException:

to point out that you know what you're doing.

All exceptions stem from BaseException, and those you're meant to catch day-to-day (those that'll be thrown for the programmer) inherit too from Exception.

It works for me by using require syntax like this:

$('.eventSlick').slick({
    dots: true,
    slidesToShow: 3,
    slidesToScroll: 1,
    autoplay: false,
    autoplaySpeed: 2000,
    arrows: true,
    draggable: false,
    prevArrow: '<button type="button" data-role="none" class="slick-prev"><img src="' + require("@/assets/img/icon/Arrow_Left.svg")+'"></button>',

Here's a variation on ashirazi's answer which doesn't rely on $IFS. It does have its own issues which I ouline below.

sentence="one;two;three"
sentence=${sentence//;/$'\n'}  # change the semicolons to white space
for word in $sentence
do
    echo "$word"
done

Here I've used a newline, but you could use a tab "\t" or a space. However, if any of those characters are in the text it will be split there, too. That's the advantage of $IFS - it can not only enable a separator, but disable the default ones. Just make sure you save its value before you change it - as others have suggested.

Here's a simple HSV color thresholder script to determine the lower/upper color ranges using trackbars for any image on the disk. Simply change the image path in cv2.imread()

import cv2
import numpy as np

def nothing(x):
    pass

# Load image
image = cv2.imread('1.jpg')

# Create a window
cv2.namedWindow('image')

# Create trackbars for color change
# Hue is from 0-179 for Opencv
cv2.createTrackbar('HMin', 'image', 0, 179, nothing)
cv2.createTrackbar('SMin', 'image', 0, 255, nothing)
cv2.createTrackbar('VMin', 'image', 0, 255, nothing)
cv2.createTrackbar('HMax', 'image', 0, 179, nothing)
cv2.createTrackbar('SMax', 'image', 0, 255, nothing)
cv2.createTrackbar('VMax', 'image', 0, 255, nothing)

# Set default value for Max HSV trackbars
cv2.setTrackbarPos('HMax', 'image', 179)
cv2.setTrackbarPos('SMax', 'image', 255)
cv2.setTrackbarPos('VMax', 'image', 255)

# Initialize HSV min/max values
hMin = sMin = vMin = hMax = sMax = vMax = 0
phMin = psMin = pvMin = phMax = psMax = pvMax = 0

while(1):
    # Get current positions of all trackbars
    hMin = cv2.getTrackbarPos('HMin', 'image')
    sMin = cv2.getTrackbarPos('SMin', 'image')
    vMin = cv2.getTrackbarPos('VMin', 'image')
    hMax = cv2.getTrackbarPos('HMax', 'image')
    sMax = cv2.getTrackbarPos('SMax', 'image')
    vMax = cv2.getTrackbarPos('VMax', 'image')

    # Set minimum and maximum HSV values to display
    lower = np.array([hMin, sMin, vMin])
    upper = np.array([hMax, sMax, vMax])

    # Convert to HSV format and color threshold
    hsv = cv2.cvtColor(image, cv2.COLOR_BGR2HSV)
    mask = cv2.inRange(hsv, lower, upper)
    result = cv2.bitwise_and(image, image, mask=mask)

    # Print if there is a change in HSV value
    if((phMin != hMin) | (psMin != sMin) | (pvMin != vMin) | (phMax != hMax) | (psMax != sMax) | (pvMax != vMax) ):
        print("(hMin = %d , sMin = %d, vMin = %d), (hMax = %d , sMax = %d, vMax = %d)" % (hMin , sMin , vMin, hMax, sMax , vMax))
        phMin = hMin
        psMin = sMin
        pvMin = vMin
        phMax = hMax
        psMax = sMax
        pvMax = vMax

You could put an index on MemberType.

You could do this:

InputStream in = new ByteArrayInputStream(string.getBytes("UTF-8"));

Note the UTF-8 encoding. You should specify the character set that you want the bytes encoded into. It's common to choose UTF-8 if you don't specifically need anything else. Otherwise if you select nothing you'll get the default encoding that can vary between systems. From the JavaDoc:

The behavior of this method when this string cannot be encoded in the default charset is unspecified. The CharsetEncoder class should be used when more control over the encoding process is required.

I had exactly the same issue. Tried everything but finally one trick worked.

1. Delete folder IISExpress from "My Documents"
2. Load your project again, it will create IISExpress folder again with updated configuration
3. Check IISExpress folder has sufficient permissions to read-write the configuration file
4. Load project again and Run IISExpress. It should work.

$a = array(1, 2, 3, 4); 
$b = array(1, 6, 5, 2, 9); 
$c = array_merge($a, $b);
$unique = array_keys(array_flip($c));
print_r($unique);

Thank you for your responses. Turns out my problem was a database issue with duplicate entries, not with my logic. A quick table sync fixed that and the SUM feature worked as expected. This is all still useful knowledge for the SUM feature and is worth reading if you are having trouble using it.

If you want to gain access to the whole the error body, do it as shown below:

 async function login(reqBody) {
  try {
    let res = await Axios({
      method: 'post',
      url: 'https://myApi.com/path/to/endpoint',
      data: reqBody
    });

    let data = res.data;
    return data;
  } catch (error) {
    console.log(error.response); // this is the main part. Use the response property from the error object

    return error.response;
  }

}

You can use git log with the pathnames of the respective folders:

git log A B

The log will only show commits made in A and B. I usually throw in --stat to make things a little prettier, which helps for quick commit reviews.

If you want to limit memory for jvm (not the heap size ) ulimit -v

To get an idea of the difference between jvm and heap memory , take a look at this excellent article http://blogs.vmware.com/apps/2011/06/taking-a-closer-look-at-sizing-the-java-process.html

The javadocs for Scanner answer your question

A Scanner breaks its input into tokens using a delimiter pattern, which by default matches whitespace.

You might change the default whitespace pattern the Scanner is using by doing something like

Scanner s = new Scanner();
s.useDelimiter("\n");

If using Visual Studio 2010 you can right-click on the project for the service, and select properties. Then select the Web tab. Under the Servers section you can configure the URL. There is also a button to create the virtual directory.

i'll make an example, first decide what browser you want to emulate, in this case i chose Firefox 60.6.1esr (64-bit), and check what GET request it issues, this can be obtained with a simple netcat server (MacOS bundles netcat, most linux distributions bunles netcat, and Windows users can get netcat from.. Cygwin.org , among other places),

setting up the netcat server to listen on port 9999: nc -l 9999

now hitting http://127.0.0.1:9999 in firefox, i get:

$ nc -l 9999
GET / HTTP/1.1
Host: 127.0.0.1:9999
User-Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:60.0) Gecko/20100101 Firefox/60.0
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Accept-Language: en-US,en;q=0.5
Accept-Encoding: gzip, deflate
Connection: keep-alive
Upgrade-Insecure-Requests: 1

now let us compare that with this simple script:

<?php
$ch=curl_init("http://127.0.0.1:9999");
curl_exec($ch);

i get:

$ nc -l 9999
GET / HTTP/1.1
Host: 127.0.0.1:9999
Accept: */*

there are several missing headers here, they can all be added with the CURLOPT_HTTPHEADER option of curl_setopt, but the User-Agent specifically should be set with CURLOPT_USERAGENT instead (it will be persistent across multiple calls to curl_exec() and if you use CURLOPT_FOLLOWLOCATION then it will persist across http redirections as well), and the Accept-Encoding header should be set with CURLOPT_ENCODING instead (if they're set with CURLOPT_ENCODING then curl will automatically decompress the response if the server choose to compress it, but if you set it via CURLOPT_HTTPHEADER then you must manually detect and decompress the content yourself, which is a pain in the ass and completely unnecessary, generally speaking) so adding those we get:

<?php
$ch=curl_init("http://127.0.0.1:9999");
curl_setopt_array($ch,array(
        CURLOPT_USERAGENT=>'Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:60.0) Gecko/20100101 Firefox/60.0',
        CURLOPT_ENCODING=>'gzip, deflate',
        CURLOPT_HTTPHEADER=>array(
                'Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8',
                'Accept-Language: en-US,en;q=0.5',
                'Connection: keep-alive',
                'Upgrade-Insecure-Requests: 1',
        ),
));
curl_exec($ch);

now running that code, our netcat server gets:

$ nc -l 9999
GET / HTTP/1.1
Host: 127.0.0.1:9999
User-Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:60.0) Gecko/20100101 Firefox/60.0
Accept-Encoding: gzip, deflate
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Accept-Language: en-US,en;q=0.5
Connection: keep-alive
Upgrade-Insecure-Requests: 1

and voila! our php-emulated browser GET request should now be indistinguishable from the real firefox GET request :)

this next part is just nitpicking, but if you look very closely, you'll see that the headers are stacked in the wrong order, firefox put the Accept-Encoding header in line 6, and our emulated GET request puts it in line 3.. to fix this, we can manually put the Accept-Encoding header in the right line,

<?php
$ch=curl_init("http://127.0.0.1:9999");
curl_setopt_array($ch,array(
        CURLOPT_USERAGENT=>'Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:60.0) Gecko/20100101 Firefox/60.0',
        CURLOPT_ENCODING=>'gzip, deflate',
        CURLOPT_HTTPHEADER=>array(
                'Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8',
                'Accept-Language: en-US,en;q=0.5',
                'Accept-Encoding: gzip, deflate',
                'Connection: keep-alive',
                'Upgrade-Insecure-Requests: 1',
        ),
));
curl_exec($ch);

running that, our netcat server gets:

$ nc -l 9999
GET / HTTP/1.1
Host: 127.0.0.1:9999
User-Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:60.0) Gecko/20100101 Firefox/60.0
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Accept-Language: en-US,en;q=0.5
Accept-Encoding: gzip, deflate
Connection: keep-alive
Upgrade-Insecure-Requests: 1

problem solved, now the headers is even in the correct order, and the request seems to be COMPLETELY INDISTINGUISHABLE from the real firefox request :) (i don't actually recommend this last step, it's a maintenance burden to keep CURLOPT_ENCODING in sync with the custom Accept-Encoding header, and i've never experienced a situation where the order of the headers are significant)

Check with your firewall expert. They open the firewall for PROD servers so there is no need to use the Proxy.

Thanks your tip helped me solve my problem:

Had to to set the Credentials in two locations to get past the 407 error:

HttpWebRequest webRequest = WebRequest.Create(uirTradeStream) as HttpWebRequest;
webRequest.Proxy = WebRequest.DefaultWebProxy;
webRequest.Credentials = new NetworkCredential("user", "password", "domain");
webRequest.Proxy.Credentials = new NetworkCredential("user", "password", "domain");

and voila!

Imagine that we have 3 buttons for example

public class MainActivity extends ActionBarActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);


        // Capture our button from layout
        Button button = (Button)findViewById(R.id.corky);
        Button button2 = (Button)findViewById(R.id.corky2);
        Button button3 = (Button)findViewById(R.id.corky3);
        // Register the onClick listener with the implementation above
        button.setOnClickListener(mCorkyListener);
        button2.setOnClickListener(mCorkyListener);
        button3.setOnClickListener(mCorkyListener);

    }

    // Create an anonymous implementation of OnClickListener
    private View.OnClickListener mCorkyListener = new View.OnClickListener() {
        public void onClick(View v) {
            // do something when the button is clicked 
            // Yes we will handle click here but which button clicked??? We don't know

        }
    };

}

So what we will do?

public class MainActivity extends ActionBarActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);


        // Capture our button from layout
        Button button = (Button)findViewById(R.id.corky);
        Button button2 = (Button)findViewById(R.id.corky2);
        Button button3 = (Button)findViewById(R.id.corky3);
        // Register the onClick listener with the implementation above
        button.setOnClickListener(mCorkyListener);
        button2.setOnClickListener(mCorkyListener);
        button3.setOnClickListener(mCorkyListener);

    }

    // Create an anonymous implementation of OnClickListener
    private View.OnClickListener mCorkyListener = new View.OnClickListener() {
        public void onClick(View v) {
            // do something when the button is clicked
            // Yes we will handle click here but which button clicked??? We don't know

            // So we will make
            switch (v.getId() /*to get clicked view id**/) {
                case R.id.corky:

                    // do something when the corky is clicked

                    break;
                case R.id.corky2:

                    // do something when the corky2 is clicked

                    break;
                case R.id.corky3:

                    // do something when the corky3 is clicked

                    break;
                default:
                    break;
            }
        }
    };

}

Or we can do this:

public class MainActivity extends ActionBarActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);


        // Capture our button from layout
        Button button = (Button)findViewById(R.id.corky);
        Button button2 = (Button)findViewById(R.id.corky2);
        Button button3 = (Button)findViewById(R.id.corky3);
        // Register the onClick listener with the implementation above
        button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                // do something when the corky is clicked
            }
        });
        button2.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                // do something when the corky2 is clicked
            }
        });
        button3.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                // do something when the corky3 is clicked
            }
        });

    }

}

Or we can implement View.OnClickListener and i think it's the best way:

public class MainActivity extends ActionBarActivity implements View.OnClickListener {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);


        // Capture our button from layout
        Button button = (Button)findViewById(R.id.corky);
        Button button2 = (Button)findViewById(R.id.corky2);
        Button button3 = (Button)findViewById(R.id.corky3);
        // Register the onClick listener with the implementation above
        button.setOnClickListener(this);
        button2.setOnClickListener(this);
        button3.setOnClickListener(this);

    }

    @Override
    public void onClick(View v) {
        // do something when the button is clicked
        // Yes we will handle click here but which button clicked??? We don't know

        // So we will make
        switch (v.getId() /*to get clicked view id**/) {
            case R.id.corky:

                // do something when the corky is clicked

                break;
            case R.id.corky2:

                // do something when the corky2 is clicked

                break;
            case R.id.corky3:

                // do something when the corky3 is clicked

                break;
            default:
                break;
        }
    }
}

Finally there is no real differences here Just "Way better than the other"

Following two steps worked perfectly fine for me:

1. Comment out the bind address from the file /etc/mysql/my.cnf:

   #bind-address = 127.0.0.1

2. Run following query in phpMyAdmin:

   GRANT ALL PRIVILEGES ON *.* TO 'root'@'%'; FLUSH PRIVILEGES;

Try VIM

If you have vim you can use this:

Not tested for every encoding.

The cool part about this is that you don't have to know the source encoding

vim +"set nobomb | set fenc=utf8 | x" filename.txt

Be aware that this command modify directly the file

Explanation part!

1. + : Used by vim to directly enter command when opening a file. Usualy used to open a file at a specific line: vim +14 file.txt
2. | : Separator of multiple commands (like ; in bash)
3. set nobomb : no utf-8 BOM
4. set fenc=utf8 : Set new encoding to utf-8 doc link
5. x : Save and close file
6. filename.txt : path to the file
7. " : qotes are here because of pipes. (otherwise bash will use them as bash pipe)

Python doesn't have builtin unsigned types. You can use mathematical operations to compute a new int representing the value you would get in C, but there is no "unsigned value" of a Python int. The Python int is an abstraction of an integer value, not a direct access to a fixed-byte-size integer.

Take a look at the GeckoFX control.

GeckoFX is an open-source component which makes it easy to embed Mozilla Gecko (Firefox) into any .NET Windows Forms application. Written in clean, fully commented C#, GeckoFX is the perfect replacement for the default Internet Explorer-based WebBrowser control.

I use this in my fragment.

Button btn1 = (Button) thisLayout
            .findViewById(R.id.btnDb1);

    btn1.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            Intent intent = new Intent(getActivity(), otherActivity.class);
            ((MainActivity) getActivity()).startActivity(intent);

        }
    });

    return thisLayout;
}

Asp.net codebehind runs on server first and then page is rendered to client (browser). Codebehind has no access to client side (javascript, html) because it lives on server only.

So, either use ajax and sent value of label to code behind. You can use PageMethods , or simply post the page to server where codebehind lives, so codebehind can know the updated value :)

in phpmyadmin

note: this will work if you delete last rows not middle rows.

goto your table-> click on operations menu-> goto table options->change AUTO_INCREMENT to that no from where you want to start.

your table autoincrement start from that no.

try it.

I had this problem (403 error for each package) and I found nothing great in the internet to solve it. My .npmrc file inside my user folder was wrong and misunderstood. I changed this npmrc line from

proxy=http://XX.XX.XXX.XXX:XXX/

to :

proxy = XX.XX.XXX.XXX:XXXX

You can use validDate.setTime(strDate) Have a look at the javadoc at http://docs.oracle.com/javase/1.5.0/docs/api/java/util/Calendar.html

If the e.target is the same element as this, you've not clicked on a descendant.

$('.foobar').on('click', function(e) {_x000D_
  if (e.target !== this)_x000D_
    return;_x000D_
  _x000D_
  alert( 'clicked the foobar' );_x000D_
});

.foobar {_x000D_
  padding: 20px; background: yellow;_x000D_
}_x000D_
span {_x000D_
  background: blue; color: white; padding: 8px;_x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>_x000D_
<div class='foobar'> .foobar (alert) _x000D_
  <span>child (no alert)</span>_x000D_
</div>

There is no need to add if{}else{} control flow. Initialise the button texts for different states at the View or ViewController constructor:

[btnCheckButton setTitle:@"Normal" forState:UIControlStateNormal];
[btnCheckButton setTitle:@"Selected" forState:UIControlStateSelected];

Then switch the button state to Selected:

[btnCheckButton setSelected:YES];

Then switch the button state to Normal:

[btnCheckButton setSelected:NO];

There is a comment by @afr0 asking how to filter on folders..

There is two ways using the GetDirectoryReference or looping through a containers blobs and checking the type. The code below is in C#

CloudBlobContainer container = blobClient.GetContainerReference("photos");

//Method 1. grab a folder reference directly from the container
CloudBlobDirectory folder = container.GetDirectoryReference("directoryName");

//Method 2. Loop over container and grab folders.
foreach (IListBlobItem item in container.ListBlobs(null, false))
{
    if (item.GetType() == typeof(CloudBlobDirectory))
    {
        // we know this is a sub directory now
        CloudBlobDirectory subFolder = (CloudBlobDirectory)item;

        Console.WriteLine("Directory: {0}", subFolder.Uri);
    }
}

read this for more in depth coverage: http://www.codeproject.com/Articles/297052/Azure-Storage-Blobs-Service-Working-with-Directori

you can read empList directly in forEach tag.Try this

 <table>
       <c:forEach items="${sessionScope.empList}" var="employee">
            <tr>
                <td>Employee ID: <c:out value="${employee.eid}"/></td>
                <td>Employee Pass: <c:out value="${employee.ename}"/></td>  
            </tr>
        </c:forEach>
    </table>

By default, Log4j logs to standard output and that means you should be able to see log messages on your Eclipse's console view. To log to a file you need to use a FileAppender explicitly by defining it in a log4j.properties file in your classpath.

Create the following log4j.properties file in your classpath. This allows you to log your message to both a file as well as your console.

log4j.rootLogger=debug, stdout, file

log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout

# Pattern to output the caller's file name and line number.
log4j.appender.stdout.layout.ConversionPattern=%5p [%t] (%F:%L) - %m%n

log4j.appender.file=org.apache.log4j.FileAppender
log4j.appender.file.File=example.log
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%p %t %c - %m%n

Note: The above creates an example.log in your current working directory (i.e. Eclipse's project directory) so that the same log4j.properties could work with different projects without overwriting each other's logs.

Easy. text = text.remove(text.length - 3). I subtracted 3 because the Remove function removes all items from that index to the end of the string which is text.length. So if I subtract 3 then I get the string with 3 characters removed from it.

You can generalize this to removing a characters from the end of the string, like this:

text = text.remove(text.length - a) 

So what I did was the same logic. The remove function removes all items from its inside to the end of the string which is the length of the text. So if I subtract a from the length of the string that will give me the string with a characters removed.

So it doesn't just work for 3, it works for all positive integers, except if the length of the string is less than or equal to a, in that case it will return a negative number or 0.

Change the code where you load the partial view to:

@Html.Partial("_CreateNote", new QuickNotes.Models.Note())

This is because the partial view is expecting a Note but is getting passed the model of the parent view which is the IEnumerable

 TimeZone tz = TimeZone.getDefault();  
Calendar cal = GregorianCalendar.getInstance(tz);
int offsetInMillis = tz.getOffset(cal.getTimeInMillis());

String offset = String.format("%02d:%02d", Math.abs(offsetInMillis / 3600000), Math.abs((offsetInMillis / 60000) % 60));
offset = (offsetInMillis >= 0 ? "+" : "-") + offset;

You want DateTime.Today.AddDays(1).

int id = getResources().getIdentifier("gameover", "drawable", getPackageName());
ImageView imageView = new ImageView(this);
LinearLayout.LayoutParams vp = 
    new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT, 
                    LayoutParams.WRAP_CONTENT);
imageView.setLayoutParams(vp);        
imageView.setImageResource(id);        
someLinearLayout.addView(imageView); 

Here are oneliners:

1. $(basename "${s%.*}")
2. $(basename "${s}" ".${s##*.}")

I needed this, the same as asked by bongbang and w4etwetewtwet.

Disable horizontal scrollbar completely by adding this code.

body{
  overflow-x: hidden;
  overflow-y: scroll;
}

Use overflow-y:auto for displaying scroll automatically when the content exceeds the divs set height.

See this demo

For python >= 3.5 subprocess.run should be used in place of subprocess.call

https://docs.python.org/3/library/subprocess.html#older-high-level-api

import subprocess
subprocess.run(['notepad.exe', 'test.txt'])

If you do not want to have a reference to the grid in the handler, you can use this code:

 $(".k-pager-refresh").trigger('click');

This will refresh the grid, if there is a refresh button. The button can be enabled like so:

[MVC GRID DECLARATION].Pageable(p=> p.Refresh(true))

Hibernate queries are case sensitive with property names (because they end up relying on getter/setter methods on the @Entity).

Make sure you refer to the property as fileName in the Criteria query, not filename.

Specifically, Hibernate will call the getter method of the filename property when executing that Criteria query, so it will look for a method called getFilename(). But the property is called FileName and the getter getFileName().

So, change the projection like so:

criteria.setProjection(Projections.property("fileName"));

Depth first search with backtracking should work here. Keep an array of boolean values to keep track of whether you visited a node before. If you run out of new nodes to go to (without hitting a node you have already been), then just backtrack and try a different branch.

The DFS is easy to implement if you have an adjacency list to represent the graph. For example adj[A] = {B,C} indicates that B and C are the children of A.

For example, pseudo-code below. "start" is the node you start from.

dfs(adj,node,visited):  
  if (visited[node]):  
    if (node == start):  
      "found a path"  
    return;  
  visited[node]=YES;  
  for child in adj[node]:  
    dfs(adj,child,visited)
  visited[node]=NO;

Call the above function with the start node:

visited = {}
dfs(adj,start,visited)

I am surprised that none of the answers mentioned the insertAdjacentHTML() method. Check it out here. The first parameter is where you want the string appended and takes ("beforebegin", "afterbegin", "beforeend", "afterend"). In the OP's situation you would use "beforeend". The second parameter is just the html string.

Basic usage:

var d1 = document.getElementById('one');
d1.insertAdjacentHTML('beforeend', '<div id="two">two</div>');

The server you're trying to download from may be badly configured. Even if it works in your browser, it may not be including all the public certificates in the chain needed for a cache-empty client to verify.

I recommend checking the site in SSLlabs tool: https://www.ssllabs.com/ssltest/

Look for this error:

This server's certificate chain is incomplete.

And this:

Chain issues.........Incomplete

In order to check if an object is compatible with a given type variable, instead of writing

u is t

you should write

typeof(t).IsInstanceOfType(u)

I think you want to return a REFCURSOR:

create function test_cursor 
            return sys_refcursor
            is
                    c_result sys_refcursor;
            begin
                    open c_result for
                    select * from dual;
                    return c_result;
            end;

Update: If you need to call this from SQL, use a table function like @Tony Andrews suggested.

Although the prior answer by brunsgaard is an efficient encoding, it works only for unsigned integers. This one builds upon it to work for both signed and unsigned integers.

def int_to_bytes(i: int, *, signed: bool = False) -> bytes:
    length = ((i + ((i * signed) < 0)).bit_length() + 7 + signed) // 8
    return i.to_bytes(length, byteorder='big', signed=signed)

def bytes_to_int(b: bytes, *, signed: bool = False) -> int:
    return int.from_bytes(b, byteorder='big', signed=signed)

# Test unsigned:
for i in range(1025):
    assert i == bytes_to_int(int_to_bytes(i))

# Test signed:
for i in range(-1024, 1025):
    assert i == bytes_to_int(int_to_bytes(i, signed=True), signed=True)

For the encoder, (i + ((i * signed) < 0)).bit_length() is used instead of just i.bit_length() because the latter leads to an inefficient encoding of -128, -32768, etc.

You may do a \d *search pattern * with asterisks to find tables that match the search pattern you're interested in.

You are getting that error because when the param1 if statements are evaluated, param is always null due to being scoped variables without delayed expansion.

When parentheses are used, all the commands and variables within those parentheses are expanded. And at that time, param1 has no value making the if statements invalid. When using delayed expansion, the variables are only expanded when the command is actually called.

Also I recommend using if not defined command to determine if a variable is set.

Per documentation, android:weightSum defines the maximum weight sum, and is calculated as the sum of the layout_weight of all the children if not specified explicitly.

Let's consider an example with a LinearLayout with horizontal orientation and 3 ImageViews inside it. Now we want these ImageViews always to take equal space. To acheive this, you can set the layout_weight of each ImageView to 1 and the weightSum will be calculated to be equal to 3 as shown in the comment.

<LinearLayout
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    <!-- android:weightSum="3" -->
    android:orientation="horizontal"
    android:layout_gravity="center">

   <ImageView
       android:layout_height="wrap_content"       
       android:layout_weight="1"
       android:layout_width="0dp"/>
  .....

weightSum is useful for having the layout rendered correctly for any device, which will not happen if you set width and height directly.

found a paper at: http://papers.ssrn.com/sol3/papers.cfm?abstract_id=1924044 that suggests a formula to calculate the downloads:

d_iPad=13,516*rank^(-0.903)
d_iPhone=52,958*rank^(-0.944)

my code works for txt,doc,docx,pdf,ppt,pptx,jpg,png,zip extensions and I think its better to use the actual MIME types explicitly.

$file_name = "a.txt";

// extracting the extension:
$ext = substr($file_name, strpos($file_name,'.')+1);

header('Content-disposition: attachment; filename='.$file_name);

if(strtolower($ext) == "txt")
{
    header('Content-type: text/plain'); // works for txt only
}
else
{
    header('Content-type: application/'.$ext); // works for all extensions except txt
}
readfile($decrypted_file_path);

You just have to send extras while calling your intent.

Like this:

Intent intent = new Intent(getApplicationContext(), SecondActivity.class);
intent.putExtra("Variable name", "Value you want to pass");
startActivity(intent);

Now on the OnCreate method of your SecondActivity you can fetch the extras like this.

If the value you sent was in long:

long value = getIntent().getLongExtra("Variable name which you sent as an extra", defaultValue(you can give it anything));

If the value you sent was a String:

String value = getIntent().getStringExtra("Variable name which you sent as an extra");

If the value you sent was a Boolean:

Boolean value = getIntent().getBooleanExtra("Variable name which you sent as an extra", defaultValue);

You should include the brackets as well . . .

<input type="checkbox" name="bla[]" value="1" />

therefore referencing it should be as be name='bla[]'

$(document).ready( function () { 

   $("input[name='bla[]']").each( function () {
       alert( $(this).val() );
   });

});

I'm a fan of:

chooseCRANmirror()

Which will print the list of mirrors in the output (no worrying a popup window since you are running it from the terminal) and then you enter the number you want.

$timeFirst  = strtotime('2011-05-12 18:20:20');
$timeSecond = strtotime('2011-05-13 18:20:20');
$differenceInSeconds = $timeSecond - $timeFirst;

You will then be able to use the seconds to find minutes, hours, days, etc.

Building upon your existing Student class, this is how I usually do it, especially if I need more than one comparator.

public class Student implements Comparable<Student> {

    String name;
    int age;

    public Student(String name, int age) {
       this.name = name;
       this.age = age;
    }

    @Override
    public String toString() {
        return name + ":" + age;
    }

    @Override
    public int compareTo(Student o) {
        return Comparators.NAME.compare(this, o);
    }


    public static class Comparators {

        public static Comparator<Student> NAME = new Comparator<Student>() {
            @Override
            public int compare(Student o1, Student o2) {
                return o1.name.compareTo(o2.name);
            }
        };
        public static Comparator<Student> AGE = new Comparator<Student>() {
            @Override
            public int compare(Student o1, Student o2) {
                return o1.age - o2.age;
            }
        };
        public static Comparator<Student> NAMEANDAGE = new Comparator<Student>() {
            @Override
            public int compare(Student o1, Student o2) {
                int i = o1.name.compareTo(o2.name);
                if (i == 0) {
                    i = o1.age - o2.age;
                }
                return i;
            }
        };
    }
}

Usage:

List<Student> studentList = new LinkedList<>();
Collections.sort(studentList, Student.Comparators.AGE);

EDIT

Since the release of Java 8 the inner class Comparators may be greatly simplified using lambdas. Java 8 also introduces a new method for the Comparator object thenComparing, which removes the need for doing manual checking of each comparator when nesting them. Below is the Java 8 implementation of the Student.Comparators class with these changes taken into account.

public static class Comparators {
    public static final Comparator<Student> NAME = (Student o1, Student o2) -> o1.name.compareTo(o2.name);
    public static final Comparator<Student> AGE = (Student o1, Student o2) -> Integer.compare(o1.age, o2.age);
    public static final Comparator<Student> NAMEANDAGE = (Student o1, Student o2) -> NAME.thenComparing(AGE).compare(o1, o2);
}
