In my experience, I often encounter the following situations;

1. If you work in a corporate company, contact the network and security team. Because in requests made to external services, it may be necessary to give permission for the relevant endpoint.

2. Another issue is that the SSL certificate may have expired on the server where your application is running.

I was getting exactly that error too: Connection reset by peer. The exception was being raised by Spring's REST template upon running the postForObject() method. For me the problem was too long HTTP URL request. So first check whether the URL produced is what it should be and, if your server really should be able to handle requests of that length, simply go to server's configuration and raise the default allowed length of URL requests.

That solved the problem for me, but be aware: the application might not run on some internet browsers, especially old ones, as they have fixed max length of URL requests.

Hope it helps...

I got this error in an application that uses AppFabric. The clue was getting a DataCacheException in the stack trace. To see if this is the issue for you, run the following PowerShell command:

@("AppFabricCachingService","RemoteRegistry") | % { get-service $_ }

If either of these two services are stopped, then you will get this error.

The correct way to 'solve' it is to close the connection and forget about the client. The client has closed the connection while you where still writing to it, so he doesn't want to know you, so that's it, isn't it?

It is possible for the TCP socket to be "closing" and your code to not have yet been notified.

Here is a animation for the life cycle. http://tcp.cs.st-andrews.ac.uk/index.shtml?page=connection_lifecycle

Basically, the connection was closed by the client. You already have throws IOException and SocketException extends IOException. This is working just fine. You just need to properly handle IOException because it is a normal part of the api.

EDIT: The RST packet occurs when a packet is received on a socket which does not exist or was closed. There is no difference to your application. Depending on the implementation the reset state may stick and closed will never officially occur.

I have got this error on open page from Google Cache.

I think, cached page(client) disconnecting on page loading.

You can ignore this error log with try-catch on filter.

First, factor consists of indices and levels. This fact is very very important when you are struggling with factor.

For example,

> z <- factor(letters[c(3, 2, 3, 4)])

# human-friendly display, but internal structure is invisible
> z
[1] c b c d
Levels: b c d

# internal structure of factor
> unclass(z)
[1] 2 1 2 3
attr(,"levels")
[1] "b" "c" "d"

here, z has 4 elements.
The index is 2, 1, 2, 3 in that order.
The level is associated with each index: 1 -> b, 2 -> c, 3 -> d.

Then, as.numeric converts simply the index part of factor into numeric.
as.character handles the index and levels, and generates character vector expressed by its level.

?as.numeric says that Factors are handled by the default method.

Problem not solved. To sufficiently model this out and to prevent code replication you'd either need multiple inheritance or mixins. Interfaces with default functions are not sufficient because you cannot hold members in interfaces. Interface modeling leads to code replication in subclasses or statics, which is both evil.

All you can do is to use a custom construction and split it up in more components and compose it all together...

For those trying to do it without using JSON, the following is how I did it:

<script>
    var originalLabels = [ '@Html.Raw(string.Join("', '", Model.labels))'];
</script>

You can use Ajax-cross-origin a jQuery plugin. With this plugin you use jQuery.ajax() cross domain. It uses Google services to achieve this:

The AJAX Cross Origin plugin use Google Apps Script as a proxy jSON getter where jSONP is not implemented. When you set the crossOrigin option to true, the plugin replace the original url with the Google Apps Script address and send it as encoded url parameter. The Google Apps Script use Google Servers resources to get the remote data, and return it back to the client as JSONP.

It is very simple to use:

    $.ajax({
        crossOrigin: true,
        url: url,
        success: function(data) {
            console.log(data);
        }
    });

You can read more here: http://www.ajax-cross-origin.com/

A simple &nbsp; between input fields would do the job easily...

I agree that it is not possible in general.

The only thing CSS3 can do (which helped in my case) is to select elements that have no children:

table td:empty
{
   background-color: white;
}

Or have any children (including text):

table td:not(:empty)
{
   background-color: white;
}

Try the following configuration:

log4j.rootLogger=TRACE, stdout

log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d [%24F:%t:%L] - %m%n

log4j.appender.debugLog=org.apache.log4j.FileAppender
log4j.appender.debugLog.File=logs/debug.log
log4j.appender.debugLog.layout=org.apache.log4j.PatternLayout
log4j.appender.debugLog.layout.ConversionPattern=%d [%24F:%t:%L] - %m%n

log4j.appender.reportsLog=org.apache.log4j.FileAppender
log4j.appender.reportsLog.File=logs/reports.log
log4j.appender.reportsLog.layout=org.apache.log4j.PatternLayout
log4j.appender.reportsLog.layout.ConversionPattern=%d [%24F:%t:%L] - %m%n

log4j.category.debugLogger=TRACE, debugLog
log4j.additivity.debugLogger=false

log4j.category.reportsLogger=DEBUG, reportsLog
log4j.additivity.reportsLogger=false

Then configure the loggers in the Java code accordingly:

static final Logger debugLog = Logger.getLogger("debugLogger");
static final Logger resultLog = Logger.getLogger("reportsLogger");

Do you want output to go to stdout? If not, change the first line of log4j.properties to:

log4j.rootLogger=OFF

and get rid of the stdout lines.

Try using rextract. It will let you extract text using a regular expression and reformat it.

Example:

$ echo "This is 02G05 a test string 20-Jul-2012" | ./rextract '([\d]+G[\d]+)' '${1}'

2G05

I believe DataFrame.fillna() will do this for you.

Link to Docs for a dataframe and for a Series.

Example:

In [7]: df
Out[7]: 
          0         1
0       NaN       NaN
1 -0.494375  0.570994
2       NaN       NaN
3  1.876360 -0.229738
4       NaN       NaN

In [8]: df.fillna(0)
Out[8]: 
          0         1
0  0.000000  0.000000
1 -0.494375  0.570994
2  0.000000  0.000000
3  1.876360 -0.229738
4  0.000000  0.000000

To fill the NaNs in only one column, select just that column. in this case I'm using inplace=True to actually change the contents of df.

In [12]: df[1].fillna(0, inplace=True)
Out[12]: 
0    0.000000
1    0.570994
2    0.000000
3   -0.229738
4    0.000000
Name: 1

In [13]: df
Out[13]: 
          0         1
0       NaN  0.000000
1 -0.494375  0.570994
2       NaN  0.000000
3  1.876360 -0.229738
4       NaN  0.000000

EDIT:

To avoid a SettingWithCopyWarning, use the built in column-specific functionality:

df.fillna({1:0}, inplace=True)

It looks like it is an extension method (in System.Net.Http.Formatting):

HttpContentExtensions Class

Update:

PM> install-package Microsoft.AspNet.WebApi.Client

According to the System.Net.Http.Formatting NuGet package page, the System.Net.Http.Formatting package is now legacy and can instead be found in the Microsoft.AspNet.WebApi.Client package available on NuGet here.

I learned all my Regex from this website: http://www.zytrax.com/tech/web/regex.htm. Google on 'Regex tutorials' and you'll find loads of helful articles.

String regex = "[a-zA-Z]*\.jpg";
System.out.println ("somthing.jpg".matches (regex));

returns true.

My solution:

jQuery('.foo').on('click',function(event){
    if ( !jQuery(event.target).is('.foo *') ) {
        // code goes here
    } 
});

The AngularJS way of calling $http would look like:

$http({
    url: "http://example.appspot.com/rest/app",
    method: "POST",
    data: {"foo":"bar"}
}).then(function successCallback(response) {
        // this callback will be called asynchronously
        // when the response is available
        $scope.data = response.data;
    }, function errorCallback(response) {
        // called asynchronously if an error occurs
        // or server returns response with an error status.
        $scope.error = response.statusText;
});

or could be written even simpler using shortcut methods:

$http.post("http://example.appspot.com/rest/app", {"foo":"bar"})
.then(successCallback, errorCallback);

There are number of things to notice:

• AngularJS version is more concise (especially using .post() method)
• AngularJS will take care of converting JS objects into JSON string and setting headers (those are customizable)
• Callback functions are named success and error respectively (also please note parameters of each callback) - Deprecated in angular v1.5
• use then function instead.
• More info of then usage can be found here

The above is just a quick example and some pointers, be sure to check AngularJS documentation for more: http://docs.angularjs.org/api/ng.$http

I'll add that arrays are very low-level constructs in C++ and you should try to stay away from them as much as possible when "learning the ropes" -- even Bjarne Stroustrup recommends this (he's the designer of C++).

Vectors come very close to the same performance as arrays, but with a great many conveniences and safety features. You'll probably start using arrays when interfacing with API's that deal with raw arrays, or when building your own collections.

You can use the XMLHttpRequest object as follows:

xhr.open("POST", url, true);
xhr.setRequestHeader("Content-Type", "application/x-www-form-urlencoded; charset=UTF-8");
xhr.send(someStuff);

That code would post someStuff to url. Just make sure that when you create your XMLHttpRequest object, it will be cross-browser compatible. There are endless examples out there of how to do that.

No, but you can use a delegate (e.g. Action) as an alternative.

Inspired in part by Robin R's answer when facing a situation where I thought I wanted an optional out parameter, I instead used an Action delegate. I've borrowed his example code to modify for use of Action<int> in order to show the differences and similarities:

public string foo(string value, Action<int> outResult = null)
{
    // .. do something

    outResult?.Invoke(100);

    return value;
}

public void bar ()
{
    string str = "bar";

    string result;
    int optional = 0;

    // example: call without the optional out parameter
    result = foo (str);
    Console.WriteLine ("Output was {0} with no optional value used", result);

    // example: call it with optional parameter
    result = foo (str, x => optional = x);
    Console.WriteLine ("Output was {0} with optional value of {1}", result, optional);

    // example: call it with named optional parameter
    foo (str, outResult: x => optional = x);
    Console.WriteLine ("Output was {0} with optional value of {1}", result, optional);
}

This has the advantage that the optional variable appears in the source as a normal int (the compiler wraps it in a closure class, rather than us wrapping it explicitly in a user-defined class).

The variable needs explicit initialisation because the compiler cannot assume that the Action will be called before the function call exits.

It's not suitable for all use cases, but worked well for my real use case (a function that provides data for a unit test, and where a new unit test needed access to some internal state not present in the return value).

The option I use is as follows:

columns.Bound(p => p.OrderDate).Format("{0:d}").ClientTemplate("#=formatDate(OrderDate)#");

function formatDate(OrderDate) {
    var formatedOrderDate = kendo.format("{0:d}", OrderDate);

    return formatedOrderDate;
}

In response to Thomas Browne's comment, because lnmx's answer only works for subtracting a date, here is a modification of his code that works for subtracting time from a time.Time type.

package main

import (
    "fmt"
    "time"
)

func main() {
    now := time.Now()

    fmt.Println("now:", now)

    count := 10
    then := now.Add(time.Duration(-count) * time.Minute)
    // if we had fix number of units to subtract, we can use following line instead fo above 2 lines. It does type convertion automatically.
    // then := now.Add(-10 * time.Minute)
    fmt.Println("10 minutes ago:", then)
}

Produces:

now: 2009-11-10 23:00:00 +0000 UTC
10 minutes ago: 2009-11-10 22:50:00 +0000 UTC

Not to mention, you can also use time.Hour or time.Second instead of time.Minute as per your needs.

If you are from the Java world, you can compare a closure with a member function of a class. Look at this example

var f=function(){
  var a=7;
  var g=function(){
    return a;
  }
  return g;
}

The function g is a closure: g closes a in. So g can be compared with a member function, a can be compared with a class field, and the function f with a class.

The manpage for git-push is worth a read. Combined with this website I wrote the following in my .git/config:

[remote "origin"]
    url = …
    fetch = …
    push = :
    push = refs/tags/*

The push = : means "push any 'matching' branches (i.e. branches that already exist in the remote repository and have a local counterpart)", while push = refs/tags/* means "push all tags".

So now I only have to run git push to push all matching branches and all tags.

Yes, this is not quite what the OP wanted (all of the branches to push must already exist on the remote side), but might be helpful for those who find this question while googling for "how do I push branches and tags at the same time".

Create key-value pairs within a foreach like this:

function createOfferUrlArray($Offer) {
    $offerArray = array();

    foreach ($Offer as $key => $value) {
        $offerArray[$key] = $value[4];
    }

    return $offerArray;
}

Use chown to change ownership and chmod to change rights.

use the -R option to apply the rights for all files inside of a directory too.

Note that both these commands just work for directories too. The -R option makes them also change the permissions for all files and directories inside of the directory.

For example

sudo chown -R username:group directory

will change ownership (both user and group) of all files and directories inside of directory and directory itself.

sudo chown username:group directory

will only change the permission of the folder directory but will leave the files and folders inside the directory alone.

you need to use sudo to change the ownership from root to yourself.

Edit:

Note that if you use chown user: file (Note the left-out group), it will use the default group for that user.

Also You can change the group ownership of a file or directory with the command:

chgrp group_name file/directory_name

You must be a member of the group to which you are changing ownership to.

You can find group of file as follows

# ls -l file
-rw-r--r-- 1 root family 0 2012-05-22 20:03 file

# chown sujit:friends file

User 500 is just a normal user. Typically user 500 was the first user on the system, recent changes (to /etc/login.defs) has altered the minimum user id to 1000 in many distributions, so typically 1000 is now the first (non root) user.

What you may be seeing is a system which has been upgraded from the old state to the new state and still has some processes knocking about on uid 500. You can likely change it by first checking if your distro should indeed now use 1000, and if so alter the login.defs file yourself, the renumber the user account in /etc/passwd and chown/chgrp all their files, usually in /home/, then reboot.

But in answer to your question, no, you should not really be worried about this in all likelihood. It'll be showing as "500" instead of a username because o user in /etc/passwd has a uid set of 500, that's all.

Also you can show your current numbers using id i'm willing to bet it comes back as 1000 for you.

I see some of the above answers are now a bit out of date. From my perspective, and I work with both Solr(Cloud and non-Cloud) and ElasticSearch on a daily basis, here are some interesting differences:

• Community: Solr has a bigger, more mature user, dev, and contributor community. ES has a smaller, but active community of users and a growing community of contributors
• Maturity: Solr is more mature, but ES has grown rapidly and I consider it stable
• Performance: hard to judge. I/we have not done direct performance benchmarks. A person at LinkedIn did compare Solr vs. ES vs. Sensei once, but the initial results should be ignored because they used non-expert setup for both Solr and ES.
• Design: People love Solr. The Java API is somewhat verbose, but people like how it's put together. Solr code is unfortunately not always very pretty. Also, ES has sharding, real-time replication, document and routing built-in. While some of this exists in Solr, too, it feels a bit like an after-thought.
• Support: there are companies providing tech and consulting support for both Solr and ElasticSearch. I think the only company that provides support for both is Sematext (disclosure: I'm Sematext founder)
• Scalability: both can be scaled to very large clusters. ES is easier to scale than pre-Solr 4.0 version of Solr, but with Solr 4.0 that's no longer the case.

For more thorough coverage of Solr vs. ElasticSearch topic have a look at https://sematext.com/blog/solr-vs-elasticsearch-part-1-overview/ . This is the first post in the series of posts from Sematext doing direct and neutral Solr vs. ElasticSearch comparison. Disclosure: I work at Sematext.

When running this command:

ALTER TABLE MYTABLENAME MODIFY CONSTRAINT MYCONSTRAINTNAME_FK ENABLE;

I got this error:

ORA-02270: no matching unique or primary key for this column-list
02270. 00000 -  "no matching unique or primary key for this column-list"
*Cause:    A REFERENCES clause in a CREATE/ALTER TABLE statement
          gives a column-list for which there is no matching unique or primary
          key constraint in the referenced table.
*Action:   Find the correct column names using the ALL_CONS_COLUMNS

The referenced table has a primary key constraint with matching type. The root cause of this error, in my case, was that the primary key constraint was disabled.

As Selman22 said, you are overriding the default object.Equals method, which accepts an object obj and not a safe compile time type.

In order for that to happen, make your type implement IEquatable<Box>:

public class Box : IEquatable<Box>
{
    double height, length, breadth;

    public static bool operator ==(Box obj1, Box obj2)
    {
        if (ReferenceEquals(obj1, obj2))
        {
            return true;
        }
        if (ReferenceEquals(obj1, null))
        {
            return false;
        }
        if (ReferenceEquals(obj2, null))
        {
            return false;
        }

        return obj1.Equals(obj2);
    }

    public static bool operator !=(Box obj1, Box obj2)
    {
        return !(obj1 == obj2);
    }

    public bool Equals(Box other)
    {
        if (ReferenceEquals(other, null))
        {
            return false;
        }
        if (ReferenceEquals(this, other))
        {
            return true;
        }

        return height.Equals(other.height) 
               && length.Equals(other.length) 
               && breadth.Equals(other.breadth);
    }

    public override bool Equals(object obj)
    {
        return Equals(obj as Box);
    }

    public override int GetHashCode()
    {
        unchecked
        {
            int hashCode = height.GetHashCode();
            hashCode = (hashCode * 397) ^ length.GetHashCode();
            hashCode = (hashCode * 397) ^ breadth.GetHashCode();
            return hashCode;
        }
    }
}

Another thing to note is that you are making a floating point comparison using the equality operator and you might experience a loss of precision.

I'm doing exactly what you're looking for in my rules engine, which uses CS-Script for dynamically compiling, loading, and running C#. It should be easily translatable into what you're looking for, and I'll give an example. First, the code (stripped-down):

using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Reflection;
using CSScriptLibrary;

namespace RulesEngine
{
    /// <summary>
    /// Make sure <typeparamref name="T"/> is an interface, not just any type of class.
    /// 
    /// Should be enforced by the compiler, but just in case it's not, here's your warning.
    /// </summary>
    /// <typeparam name="T"></typeparam>
    public class RulesEngine<T> where T : class
    {
        public RulesEngine(string rulesScriptFileName, string classToInstantiate)
            : this()
        {
            if (rulesScriptFileName == null) throw new ArgumentNullException("rulesScriptFileName");
            if (classToInstantiate == null) throw new ArgumentNullException("classToInstantiate");

            if (!File.Exists(rulesScriptFileName))
            {
                throw new FileNotFoundException("Unable to find rules script", rulesScriptFileName);
            }

            RulesScriptFileName = rulesScriptFileName;
            ClassToInstantiate = classToInstantiate;

            LoadRules();
        }

        public T @Interface;

        public string RulesScriptFileName { get; private set; }
        public string ClassToInstantiate { get; private set; }
        public DateTime RulesLastModified { get; private set; }

        private RulesEngine()
        {
            @Interface = null;
        }

        private void LoadRules()
        {
            if (!File.Exists(RulesScriptFileName))
            {
                throw new FileNotFoundException("Unable to find rules script", RulesScriptFileName);
            }

            FileInfo file = new FileInfo(RulesScriptFileName);

            DateTime lastModified = file.LastWriteTime;

            if (lastModified == RulesLastModified)
            {
                // No need to load the same rules twice.
                return;
            }

            string rulesScript = File.ReadAllText(RulesScriptFileName);

            Assembly compiledAssembly = CSScript.LoadCode(rulesScript, null, true);

            @Interface = compiledAssembly.CreateInstance(ClassToInstantiate).AlignToInterface<T>();

            RulesLastModified = lastModified;
        }
    }
}

This will take an interface of type T, compile a .cs file into an assembly, instantiate a class of a given type, and align that instantiated class to the T interface. Basically, you just have to make sure the instantiated class implements that interface. I use properties to setup and access everything, like so:

private RulesEngine<IRulesEngine> rulesEngine;

public RulesEngine<IRulesEngine> RulesEngine
{
    get
    {
        if (null == rulesEngine)
        {
            string rulesPath = Path.Combine(Application.StartupPath, "Rules.cs");

            rulesEngine = new RulesEngine<IRulesEngine>(rulesPath, typeof(Rules).FullName);
        }

        return rulesEngine;
    }
}

public IRulesEngine RulesEngineInterface
{
    get { return RulesEngine.Interface; }
}

For your example, you want to call Run(), so I'd make an interface that defines the Run() method, like this:

public interface ITestRunner
{
    void Run();
}

Then make a class that implements it, like this:

public class TestRunner : ITestRunner
{
    public void Run()
    {
        // implementation goes here
    }
}

Change the name of RulesEngine to something like TestHarness, and set your properties:

private TestHarness<ITestRunner> testHarness;

public TestHarness<ITestRunner> TestHarness
{
    get
    {
        if (null == testHarness)
        {
            string sourcePath = Path.Combine(Application.StartupPath, "TestRunner.cs");

            testHarness = new TestHarness<ITestRunner>(sourcePath , typeof(TestRunner).FullName);
        }

        return testHarness;
    }
}

public ITestRunner TestHarnessInterface
{
    get { return TestHarness.Interface; }
}

Then, anywhere you want to call it, you can just run:

ITestRunner testRunner = TestHarnessInterface;

if (null != testRunner)
{
    testRunner.Run();
}

It would probably work great for a plugin system, but my code as-is is limited to loading and running one file, since all of our rules are in one C# source file. I would think it'd be pretty easy to modify it to just pass in the type/source file for each one you wanted to run, though. You'd just have to move the code from the getter into a method that took those two parameters.

Also, use your IRunnable in place of ITestRunner.

Just a small observation: you keep mentioning conn usr\pass, and this is a typo, right? Cos it should be conn usr/pass. Or is it different on a Unix based OS?

Furthermore, just to be sure: if you use tnsnames, your login string will look different from when you use the login method you started this topic out with.

tnsnames.ora should be in $ORACLE_HOME$\network\admin. That is the Oracle home on the machine from which you are trying to connect, so in your case your PC. If you have multiple oracle_homes and wish to use only one tnsnames.ora, you can set environment variable tns_admin (e.g. set TNS_ADMIN=c:\oracle\tns), and place tnsnames.ora in that directory.

Your original method of logging on (usr/[email protected]:port/servicename) should always work. So far I think you have all the info, except for the port number, which I am sure your DBA will be able to give you. If this method still doesn't work, either the server's IP address is not available from your client, or it is a firewall issue (blocking a certain port), or something else not (directly) related to Oracle or SQL*Plus.

The Icon property for a project specifies the icon file (.ico) that will be displayed for the compiled application in Windows Explorer and in the Windows taskbar.

The Icon property can be accessed in the Application pane of the Project Designer; it contains a list of icons that have been added to a project either as resources or as content files.

To specify an application icon

1. With a project selected in Solution Explorer, on the Project menu click Properties.
2. Select the Application pane.
3. Select an icon (.ico) file from the Icon drop-down list.

To specify an application icon and add it to your project

1. With a project selected in Solution Explorer, on the Project menu, click Properties.
2. Select the Application pane.
3. Select Browse from the Icon drop-down list and browse to the location of the icon file that you want.

The icon file is added to your project as a content file and can be seen on top left corner.

And if you want to show separate icons for every form you have to go to each form's properties, select icon attribute and browse for an icon you want.

Here's MSDN link for the same purpose...

Hope this helps.

A colleague and I have created a tool just for this. It's a visual representation of all the locks that your sessions produce. Give it a try (http://www.sqllockfinder.com), it's open source (https://github.com/LucBos/SqlLockFinder)

You could try something like:

    WebElement rxBtn = driver.findElement(By.className("icon-rx"));
    WebElement otcBtn = driver.findElement(By.className("icon-otc"));
    WebElement herbBtn = driver.findElement(By.className("icon-herb"));

    Assert.assertEquals(true, rxBtn.isDisplayed());
    Assert.assertEquals(true, otcBtn.isDisplayed());
    Assert.assertEquals(true, herbBtn.isDisplayed());

This is just an example. Basically you declare and define the WebElement variables you wish to use and then Assert whether or not they are displayed. This is using TestNG Assertions.

The following website has both right click and view source disabled.

They fooled you. Just scroll down in view-source.

Furthermore, employing such tactics marks you as unprofessional. Don’t do it.

List<? extends HasWord> accepts any concrete classes that extends HasWord. If you have the following classes...

public class A extends HasWord { .. }
public class B extends HasWord { .. }
public class C { .. }
public class D extends SomeOtherWord { .. }

... the wordList can ONLY contain a list of either As or Bs or mixture of both because both classes extend the same parent or null (which fails instanceof checks for HasWorld).

if you want to remove all elements with matching ID parts, for example:

<span id='myID_123'>
<span id='myID_456'>
<span id='myID_789'>

try this:

$("span[id*=myID]").remove();

don't forget the '*' - this will remove them all at once - cheers

Working Demo

foreach over a statement is just a syntax sugar for the regular one-way fetch() loop. If you want to loop over your data more than once, select it as a regular array first

$sql = "SELECT * FROM users";
$stm = $dbh->query($sql);
// here you go:
$users = $stm->fetchAll();

foreach ($users as $row) {
    print $row["name"] . "-" . $row["sex"] ."<br/>";
}
echo "<br/>";
foreach ($users as $row) {
    print $row["name"] . "-" . $row["sex"] ."<br/>";
}

Also quit that try..catch thing. Don't use it, but set the proper error reporting for PHP and PDO

updated:

startdate = "20.03.2014";
var new_date = moment(startdate, "DD-MM-YYYY").add(5,'days');

alert(new_date)

If you are using Notepad++ editor Goto ctrl + F choose tab 3 find in files and enter:

1. Find What = text1*.*text2
2. Filters : .
3. Search mode = Regular Expression
4. Directory = enter the path of the directory you want to search in. You can check Follow current doc. to have the path of the current file to be filled.

If you wanted to change the title from a child view controller of a Page View Controller that's embedded in a navigation controller, it would look like this:

override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(animated)
    self.parent?.title = "some title"
}

Essentially, and as-noted by @kevin-b:

// find('#id')
angular.element(document.querySelector('#id'))

//find('.classname'), assumes you already have the starting elem to search from
angular.element(elem.querySelector('.classname'))

Note: If you're looking to do this from your controllers you may want to have a look at the "Using Controllers Correctly" section in the developers guide and refactor your presentation logic into appropriate directives (such as <a2b ...>).

I had read yesterday that the issue was fixed for someone when that person cleared cookies. I had tried that but it did not work for me.

Checking the following section in DatabaseInterface.class.php,

        define(
            'PMA_MYSQL_INT_VERSION',
            PMA_Util::cacheGet('PMA_MYSQL_INT_VERSION', true)
        );

I figured that somehow cache is the problem. So, I remembered that I was restarting the service instead of doing a start and stop.

# restart the service
systemd restart php-fpm

# start and stop the service
systemd stop php-fpm
systemd start php-fpm

Doing a stop followed by a start fixed the issue for me.

I used another repository for oracle java.

sudo add-apt-repository ppa:linuxuprising/java
sudo apt-get update

sudo apt install  oracle-java11-installer

The rules (which did not change in C++11):

• Reserved in any scope, including for use as implementation macros:
  • identifiers beginning with an underscore followed immediately by an uppercase letter
  • identifiers containing adjacent underscores (or "double underscore")
• Reserved in the global namespace:
  • identifiers beginning with an underscore
• Also, everything in the std namespace is reserved. (You are allowed to add template specializations, though.)

From the 2003 C++ Standard:

17.4.3.1.2 Global names [lib.global.names]

Certain sets of names and function signatures are always reserved to the implementation:

• Each name that contains a double underscore (__) or begins with an underscore followed by an uppercase letter (2.11) is reserved to the implementation for any use.
• Each name that begins with an underscore is reserved to the implementation for use as a name in the global namespace.¹⁶⁵

¹⁶⁵⁾ Such names are also reserved in namespace ::std (17.4.3.1).

Because C++ is based on the C standard (1.1/2, C++03) and C99 is a normative reference (1.2/1, C++03) these also apply, from the 1999 C Standard:

7.1.3 Reserved identifiers

Each header declares or defines all identifiers listed in its associated subclause, and optionally declares or defines identifiers listed in its associated future library directions subclause and identifiers which are always reserved either for any use or for use as file scope identifiers.

• All identifiers that begin with an underscore and either an uppercase letter or another underscore are always reserved for any use.
• All identifiers that begin with an underscore are always reserved for use as identifiers with file scope in both the ordinary and tag name spaces.
• Each macro name in any of the following subclauses (including the future library directions) is reserved for use as specified if any of its associated headers is included; unless explicitly stated otherwise (see 7.1.4).
• All identifiers with external linkage in any of the following subclauses (including the future library directions) are always reserved for use as identifiers with external linkage.¹⁵⁴
• Each identifier with file scope listed in any of the following subclauses (including the future library directions) is reserved for use as a macro name and as an identifier with file scope in the same name space if any of its associated headers is included.

No other identifiers are reserved. If the program declares or defines an identifier in a context in which it is reserved (other than as allowed by 7.1.4), or defines a reserved identifier as a macro name, the behavior is undefined.

If the program removes (with #undef) any macro definition of an identifier in the first group listed above, the behavior is undefined.

¹⁵⁴⁾ The list of reserved identifiers with external linkage includes errno, math_errhandling, setjmp, and va_end.

Other restrictions might apply. For example, the POSIX standard reserves a lot of identifiers that are likely to show up in normal code:

• Names beginning with a capital E followed a digit or uppercase letter:
  • may be used for additional error code names.
• Names that begin with either is or to followed by a lowercase letter
  • may be used for additional character testing and conversion functions.
• Names that begin with LC_ followed by an uppercase letter
  • may be used for additional macros specifying locale attributes.
• Names of all existing mathematics functions suffixed with f or l are reserved
  • for corresponding functions that operate on float and long double arguments, respectively.
• Names that begin with SIG followed by an uppercase letter are reserved
  • for additional signal names.
• Names that begin with SIG_ followed by an uppercase letter are reserved
  • for additional signal actions.
• Names beginning with str, mem, or wcs followed by a lowercase letter are reserved
  • for additional string and array functions.
• Names beginning with PRI or SCN followed by any lowercase letter or X are reserved
  • for additional format specifier macros
• Names that end with _t are reserved
  • for additional type names.

While using these names for your own purposes right now might not cause a problem, they do raise the possibility of conflict with future versions of that standard.

Personally I just don't start identifiers with underscores. New addition to my rule: Don't use double underscores anywhere, which is easy as I rarely use underscore.

After doing research on this article I no longer end my identifiers with _t as this is reserved by the POSIX standard.

The rule about any identifier ending with _t surprised me a lot. I think that is a POSIX standard (not sure yet) looking for clarification and official chapter and verse. This is from the GNU libtool manual, listing reserved names.

CesarB provided the following link to the POSIX 2004 reserved symbols and notes 'that many other reserved prefixes and suffixes ... can be found there'. The POSIX 2008 reserved symbols are defined here. The restrictions are somewhat more nuanced than those above.

If the response is in json you could do something like (python3):

import json
import requests as reqs

# Make the HTTP request.
response = reqs.get('http://demo.ckan.org/api/3/action/group_list')

# Use the json module to load CKAN's response into a dictionary.
response_dict = json.loads(response.text)

for i in response_dict:
    print("key: ", i, "val: ", response_dict[i])

To see everything in the response you can use .__dict__:

print(response.__dict__)

You cat use setVisible () method of JFrame (and set visibility to false) or dispose () method which is more similar to close operation.

After running into the same issue - here're some of my thoughts:

• due to Chrome removing support for h264, on some machines, mp4 videos encoded with it will either not work (throwing an Parser error when viewing under Firebug/Network tab - consistent with issue submitted here), or crash the browser, depending upon the encoding settings
• it isn't consistent - it entirely depends upon the codecs installed on the computer - while I didn't encounter this issue on my machine, we did have one in the office where the issue occurred (and thus we used this one for testing)
• it might to do with Quicktime / divX settings (the machine in question had an older version of Quicktime than my native one - we didn't want to loose our testing pc though, so we didn't update it).

As it affects only Chrome (other browsers work fine with VideoForEverybody solution) the solution I've used is:

for every mp4 file, create a Theora encoded mp4 file (example.mp4 -> example_c.mp4) apply following js:

if (window.chrome)
    $("[type=video\\\/mp4]").each(function()
    {
        $(this).attr('src', $(this).attr('src').replace(".mp4", "_c.mp4"));
    });

Unfortunately it's a bad Chrome hack, but hey, at least it works.

This also can help: chrome could play html5 mp4 video but html5test said chrome did not support mp4 video codec

Also check your version of crome here: html5test

Perhaps use plt.annotate:

import numpy as np
import matplotlib.pyplot as plt

N = 10
data = np.random.random((N, 4))
labels = ['point{0}'.format(i) for i in range(N)]

plt.subplots_adjust(bottom = 0.1)
plt.scatter(
    data[:, 0], data[:, 1], marker='o', c=data[:, 2], s=data[:, 3] * 1500,
    cmap=plt.get_cmap('Spectral'))

for label, x, y in zip(labels, data[:, 0], data[:, 1]):
    plt.annotate(
        label,
        xy=(x, y), xytext=(-20, 20),
        textcoords='offset points', ha='right', va='bottom',
        bbox=dict(boxstyle='round,pad=0.5', fc='yellow', alpha=0.5),
        arrowprops=dict(arrowstyle = '->', connectionstyle='arc3,rad=0'))

plt.show()

Surprising to see nobody mentioned document.hasFocus

if (document.hasFocus()) console.log('Tab is active')

MDN has more information.

if you want same string output then try below else use without double quotes for proper output

$str = '20130814';
  echo date('"F Y"', strtotime($str));

//output  : "August 2013" 

I wish that I could just comment on yojimbo87's answer to post this, but I don't have enough reputation to comment yet. It was pointed out that this relative path only works from the root:

        window.location.href = "/{controller}/{action}/{params}";

Just wanted to confirm that you can use @Url.Content to provide the absolute path:

function DeleteJob() {
    if (confirm("Do you really want to delete selected job/s?"))
        window.location.href = '@Url.Content("~/{controller}/{action}/{params}")';
    else
        return false;
}

You may consider 3rd party tool that called Excel Jetcell .NET component for read/write excel files:

C# sample

// Create New Excel Workbook
ExcelWorkbook Wbook = new ExcelWorkbook();
ExcelCellCollection Cells = Wbook.Worksheets.Add("Sheet1").Cells;

Cells["A1"].Value = "Excel writer example (C#)";
Cells["A1"].Style.Font.Bold = true;
Cells["B1"].Value = "=550 + 5";

// Write Excel XLS file
Wbook.WriteXLS("excel_net.xls");

VB.NET sample

' Create New Excel Workbook
Dim Wbook As ExcelWorkbook = New ExcelWorkbook()
Dim Cells As ExcelCellCollection = Wbook.Worksheets.Add("Sheet1").Cells

Cells("A1").Value = "Excel writer example (C#)"
Cells("A1").Style.Font.Bold = True
Cells("B1").Value = "=550 + 5"

' Write Excel XLS file
Wbook.WriteXLS("excel_net.xls")

For Windows. Run these commands in Git Bash:

git config --global diff.tool meld
git config --global difftool.meld.path "C:\Program Files (x86)\Meld\Meld.exe"
git config --global difftool.prompt false

git config --global merge.tool meld
git config --global mergetool.meld.path "C:\Program Files (x86)\Meld\Meld.exe"
git config --global mergetool.prompt false

(Update the file path for Meld.exe if yours is different.)

For Linux. Run these commands in Git Bash:

git config --global diff.tool meld
git config --global difftool.meld.path "/usr/bin/meld"
git config --global difftool.prompt false

git config --global merge.tool meld
git config --global mergetool.meld.path "/usr/bin/meld"
git config --global mergetool.prompt false

You can verify Meld's path using this command:

which meld

You get a nice header output with the following command:

 curl -L -v -s -o /dev/null google.de

• -L, --location follow redirects
• -v, --verbose more output, indicates the direction
• -s, --silent don't show a progress bar
• -o, --output /dev/null don't show received body

Or the shorter version:

 curl -Lvso /dev/null google.de

Results in:

As you can see curl outputs both the outgoing and the incoming headers and skips the bodydata althought telling you how big the body is.

Additionally for every line the direction is indicated so that it is easy to read. I found it particular useful to trace down long chains of redirects.

I think its a bug in android..It can be fixed by adding this patch :)
Check these links question 1 and question 2

Hope it will be useful.

How about:

<asp:HtmlIframe ID="yourIframe" runat="server" />

Is supported since .Net Framework 4.5

If you have Problems using this control, you might take a look here.

Well, you already have good answers, but they're most Lambda. A more LINQ approach would be like

var NotSentMessages =
                from msg in MsgList
                where !SentList.Any(x => x.MsgID == msg.MsgID)
                select msg;

A simple Javascript function that makes the content inside a page-element unselectable:

function makeUnselectable(elem) {
  if (typeof(elem) == 'string')
    elem = document.getElementById(elem);
  if (elem) {
    elem.onselectstart = function() { return false; };
    elem.style.MozUserSelect = "none";
    elem.style.KhtmlUserSelect = "none";
    elem.unselectable = "on";
  }
}

Use apply function,

Xlower = df['x'].apply(lambda x: x.upper()).head(10) 

You can do this in a one line LINQ statement. OK, I realise this is not necessarily the fastest, so doesn't technically answer the question, but it's probably the easiest to write:

str.All(c => c >= '0' && c <= '9')

This code will add an event listener to the default local Inbox, then take some action on incoming emails. You need to add that action in the code below.

Private WithEvents Items As Outlook.Items 
Private Sub Application_Startup() 
  Dim olApp As Outlook.Application 
  Dim objNS As Outlook.NameSpace 
  Set olApp = Outlook.Application 
  Set objNS = olApp.GetNamespace("MAPI") 
  ' default local Inbox
  Set Items = objNS.GetDefaultFolder(olFolderInbox).Items 
End Sub
Private Sub Items_ItemAdd(ByVal item As Object) 

  On Error Goto ErrorHandler 
  Dim Msg As Outlook.MailItem 
  If TypeName(item) = "MailItem" Then
    Set Msg = item 
    ' ******************
    ' do something here
    ' ******************
  End If
ProgramExit: 
  Exit Sub
ErrorHandler: 
  MsgBox Err.Number & " - " & Err.Description 
  Resume ProgramExit 
End Sub

After pasting the code in ThisOutlookSession module, you must restart Outlook.

I used Retrofit 2.0 for my register users, send multipart/form File image and text from register account

In my RegisterActivity, use an AsyncTask

//AsyncTask
private class Register extends AsyncTask<String, Void, String> {

    @Override
    protected void onPreExecute() {..}

    @Override
    protected String doInBackground(String... params) {
        new com.tequilasoft.mesasderegalos.dbo.Register().register(txtNombres, selectedImagePath, txtEmail, txtPassword);
        responseMensaje = StaticValues.mensaje ;
        mensajeCodigo = StaticValues.mensajeCodigo;
        return String.valueOf(StaticValues.code);
    }

    @Override
    protected void onPostExecute(String codeResult) {..}

And in my Register.java class is where use Retrofit with synchronous call

You can extract a private key from a keystore with Java6 and OpenSSL. This all depends on the fact that both Java and OpenSSL support PKCS#12-formatted keystores. To do the extraction, you first use keytool to convert to the standard format. Make sure you use the same password for both files (private key password, not the keystore password) or you will get odd failures later on in the second step.

keytool -importkeystore -srckeystore keystore.jks \
    -destkeystore intermediate.p12 -deststoretype PKCS12

Next, use OpenSSL to do the extraction to PEM:

openssl pkcs12 -in intermediate.p12 -out extracted.pem -nodes

You should be able to handle that PEM file easily enough; it's plain text with an encoded unencrypted private key and certificate(s) inside it (in a pretty obvious format).

When you do this, take care to keep the files created secure. They contain secret credentials. Nothing will warn you if you fail to secure them correctly. The easiest method for securing them is to do all of this in a directory which doesn't have any access rights for anyone other than the user. And never put your password on the command line or in environment variables; it's too easy for other users to grab.

I needed a way to repeat/loop an array (with n items) m times.

For example, distributing a list (of persons) to a week/month. Let's say I have 3 names, and I want to them to repeat in a week:

fillArray(["Adam", "Blair", "Curtis"], 7); // returns ["Adam", "Blair", "Curtis", "Adam", "Blair", "Curtis", "Adam"]

function fillArray(pattern, count) {
    let result = [];
    if (["number", "string"].includes(typeof pattern)) {
        result = new Array(5);
        result.fill(pattern);
    }
    else if (pattern instanceof Array) {
        for (let i = 0; i < count; i++) {
            result = result.concat(pattern);
        }
        result = result.slice(0, count);
    }
    return result;
}

fillArray("a", 5);        // ["a", "a", "a", "a", "a"]
fillArray(1, 5);          // [1, 1, 1, 1, 1]
fillArray(["a", "b"], 5); // ["a", "b", "a", "b", "a"]

There are scripts on CPAN which attempt to uninstall modules:

• pm-uninstall
• perlrocks

ExtUtils::Packlist shows sample module removing code, modrm.

This is probably the best option in C#.

If you want to know if the string contains a whole number (integer):

string someString;
// ...
int myInt;
bool isNumerical = int.TryParse(someString, out myInt);

The TryParse method will try to convert the string to a number (integer) and if it succeeds it will return true and place the corresponding number in myInt. If it can't, it returns false.

Solutions using the int.Parse(someString) alternative shown in other responses works, but it is much slower because throwing exceptions is very expensive. TryParse(...) was added to the C# language in version 2, and until then you didn't have a choice. Now you do: you should therefore avoid the Parse() alternative.

If you want to accept decimal numbers, the decimal class also has a .TryParse(...) method. Replace int with decimal in the above discussion, and the same principles apply.

Assuming that you are using Java 1.5, and that you cannot add Google Collections, I would do something very similar to what the Google guys did. This is a slight variation on Jon's comments.

First add this interface to your codebase.

public interface IPredicate<T> { boolean apply(T type); }

Its implementers can answer when a certain predicate is true of a certain type. E.g. If T were User and AuthorizedUserPredicate<User> implements IPredicate<T>, then AuthorizedUserPredicate#apply returns whether the passed in User is authorized.

Then in some utility class, you could say

public static <T> Collection<T> filter(Collection<T> target, IPredicate<T> predicate) {
    Collection<T> result = new ArrayList<T>();
    for (T element: target) {
        if (predicate.apply(element)) {
            result.add(element);
        }
    }
    return result;
}

So, assuming that you have the use of the above might be

Predicate<User> isAuthorized = new Predicate<User>() {
    public boolean apply(User user) {
        // binds a boolean method in User to a reference
        return user.isAuthorized();
    }
};
// allUsers is a Collection<User>
Collection<User> authorizedUsers = filter(allUsers, isAuthorized);

If performance on the linear check is of concern, then I might want to have a domain object that has the target collection. The domain object that has the target collection would have filtering logic for the methods that initialize, add and set the target collection.

UPDATE:

In the utility class (let's say Predicate), I have added a select method with an option for default value when the predicate doesn't return the expected value, and also a static property for params to be used inside the new IPredicate.

public class Predicate {
    public static Object predicateParams;

    public static <T> Collection<T> filter(Collection<T> target, IPredicate<T> predicate) {
        Collection<T> result = new ArrayList<T>();
        for (T element : target) {
            if (predicate.apply(element)) {
                result.add(element);
            }
        }
        return result;
    }

    public static <T> T select(Collection<T> target, IPredicate<T> predicate) {
        T result = null;
        for (T element : target) {
            if (!predicate.apply(element))
                continue;
            result = element;
            break;
        }
        return result;
    }

    public static <T> T select(Collection<T> target, IPredicate<T> predicate, T defaultValue) {
        T result = defaultValue;
        for (T element : target) {
            if (!predicate.apply(element))
                continue;
            result = element;
            break;
        }
        return result;
    }
}

The following example looks for missing objects between collections:

List<MyTypeA> missingObjects = (List<MyTypeA>) Predicate.filter(myCollectionOfA,
    new IPredicate<MyTypeA>() {
        public boolean apply(MyTypeA objectOfA) {
            Predicate.predicateParams = objectOfA.getName();
            return Predicate.select(myCollectionB, new IPredicate<MyTypeB>() {
                public boolean apply(MyTypeB objectOfB) {
                    return objectOfB.getName().equals(Predicate.predicateParams.toString());
                }
            }) == null;
        }
    });

The following example, looks for an instance in a collection, and returns the first element of the collection as default value when the instance is not found:

MyType myObject = Predicate.select(collectionOfMyType, new IPredicate<MyType>() {
public boolean apply(MyType objectOfMyType) {
    return objectOfMyType.isDefault();
}}, collectionOfMyType.get(0));

UPDATE (after Java 8 release):

It's been several years since I (Alan) first posted this answer, and I still cannot believe I am collecting SO points for this answer. At any rate, now that Java 8 has introduced closures to the language, my answer would now be considerably different, and simpler. With Java 8, there is no need for a distinct static utility class. So if you want to find the 1st element that matches your predicate.

final UserService userService = ... // perhaps injected IoC
final Optional<UserModel> userOption = userCollection.stream().filter(u -> {
    boolean isAuthorized = userService.isAuthorized(u);
    return isAuthorized;
}).findFirst();

The JDK 8 API for optionals has the ability to get(), isPresent(), orElse(defaultUser), orElseGet(userSupplier) and orElseThrow(exceptionSupplier), as well as other 'monadic' functions such as map, flatMap and filter.

If you want to simply collect all the users which match the predicate, then use the Collectors to terminate the stream in the desired collection.

final UserService userService = ... // perhaps injected IoC
final List<UserModel> userOption = userCollection.stream().filter(u -> {
    boolean isAuthorized = userService.isAuthorized(u);
    return isAuthorized;
}).collect(Collectors.toList());

See here for more examples on how Java 8 streams work.

containerObject = new JSONObject(container);
if (containerObject.has("video")) { 
   //get Value of video
}

Following up as of 2019-04-04, this seems to be able to be accomplished with the React Hooks' useState:

import React, { useState } from 'react'
import uniqueId from 'lodash/utility/uniqueId'

const Field = props => {
  const [ id ] = useState(uniqueId('myprefix-'))

  return (
    <div>
      <label htmlFor={id}>{props.label}</label>
      <input id={id} type="text"/>
    </div>
  )      
}

export default Field

As I understand it, you ignore the second array item in the array destructuring that would allow you to update id, and now you've got a value that won't be updated again for the life of the component.

The value of id will be myprefix-<n> where <n> is an incremental integer value returned from uniqueId. If that's not unique enough for you, consider making your own like

function gen4() {
  return Math.random().toString(16).slice(-4)
}

function simpleUniqueId(prefix) {
  return (prefix || '').concat([
    gen4(),
    gen4(),
    gen4(),
    gen4(),
    gen4(),
    gen4(),
    gen4(),
    gen4()
  ].join(''))
}

or check out the library I published with this here: https://github.com/rpearce/simple-uniqueid. There are also hundreds or thousands of other unique ID things out there, but lodash's uniqueId with a prefix should be enough to get the job done.

Update 2019-07-10

Thanks to @Huong Hk for pointing me to hooks lazy initial state, the sum of which is that you can pass a function to useState that will only be run on the initial mount.

// before
const [ id ] = useState(uniqueId('myprefix-'))

// after
const [ id ] = useState(() => uniqueId('myprefix-'))

Combining multiple answers, here's a command that works on both Linux and MacOS

rm -rf $(find . -type d -name __pycache__)

I found this post because I was having the same error in Microsoft Visual C++. (Though it seems it's cause was a little different, than the above posted question.)

I had placed the file, I was trying to include, in the same directory, but it still could not be found.

My include looked like this: #include <ftdi.h>

But When I changed it to this: #include "ftdi.h" then it found it.

$('#demolist li').on('click', function(){
    $('#datebox').val($(this).text());
});

Like this:

<c:forEach var="entry" items="${myMap}">
  Key: <c:out value="${entry.key}"/>
  Value: <c:out value="${entry.value}"/>
</c:forEach>

' = "

/ = \ = \\

example :

f = open('c:\word.txt', 'r')
f = open("c:\word.txt", "r")
f = open("c:/word.txt", "r")
f = open("c:\\\word.txt", "r")

Results are the same

=>> no, they're not the same. A single backslash will escape characters. You just happen to luck out in that example because \k and \w aren't valid escapes like \t or \n or \\ or \"

If you want to use single backslashes (and have them interpreted as such), then you need to use a "raw" string. You can do this by putting an 'r' in front of the string

im_raw = r'c:\temp.txt'
non_raw = 'c:\\temp.txt'
another_way = 'c:/temp.txt'

As far as paths in Windows are concerned, forward slashes are interpreted the same way. Clearly the string itself is different though. I wouldn't guarantee that they're handled this way on an external device though.

var checkbox = $( "#checkbox" );
checkbox.val( checkbox[0].checked ? "true" : "false" );

This will set the value of the checkbox to "true" or "false" (value property is a string), depending whether it's unchecked or checked.

Works in jQuery >= 1.0

Normaly you can GET and POST parameters in a servlet the same way:

request.getParameter("cmd");

But only if the POST data is encoded as key-value pairs of content type: "application/x-www-form-urlencoded" like when you use a standard HTML form.

If you use a different encoding schema for your post data, as in your case when you post a json data stream, you need to use a custom decoder that can process the raw datastream from:

BufferedReader reader = request.getReader();

Json post processing example (uses org.json package )

public void doPost(HttpServletRequest request, HttpServletResponse response)
  throws ServletException, IOException {

  StringBuffer jb = new StringBuffer();
  String line = null;
  try {
    BufferedReader reader = request.getReader();
    while ((line = reader.readLine()) != null)
      jb.append(line);
  } catch (Exception e) { /*report an error*/ }

  try {
    JSONObject jsonObject =  HTTP.toJSONObject(jb.toString());
  } catch (JSONException e) {
    // crash and burn
    throw new IOException("Error parsing JSON request string");
  }

  // Work with the data using methods like...
  // int someInt = jsonObject.getInt("intParamName");
  // String someString = jsonObject.getString("stringParamName");
  // JSONObject nestedObj = jsonObject.getJSONObject("nestedObjName");
  // JSONArray arr = jsonObject.getJSONArray("arrayParamName");
  // etc...
}

Try this

$client = new \GuzzleHttp\Client();
$client->post(
    'http://www.example.com/user/create',
    array(
        'form_params' => array(
            'email' => '[email protected]',
            'name' => 'Test user',
            'password' => 'testpassword'
        )
    )
);

<script type="text/javascript">
$(document).ready(function(){
    $('.nav li').click(function(){
        $(this).addClass('active');
        $(this).siblings().removeClass('active');

    });

});

As DimtryB mentioned, by default the keystore is under the user directory. But if you are trying to update the cacerts file, so that the JVM can pick the keys, then you will have to update the cacerts file under jre/lib/security. You can also view the keys by executing the command keytool -list -keystore cacerts to see if your certificate is added.

Not unless you make all variables "public", i.e. make them members of the Function either directly or through the prototype property.

var C = function( ) {
    this.x = 10 , this.y = 20 ;
    this.modify = function( ) {
        this.x = 30 , this.y = 40 ;
        console.log("(!) C >> " + (this.x + this.y) ) ;
    } ;
} ;

var A = function( ) {
    this.modify = function( ) {
       this.x = 300 , this.y = 400 ;
       console.log("(!) A >> " + (this.x + this.y) ) ;
    } ;
} ;
    A.prototype = new C ;

var B = function( ) {
    this.modify = function( ) {
       this.x = 3000 , this.y = 4000 ;
       console.log("(!) B >> " + (this.x + this.y) ) ;
    } ;
} ;


new C( ).modify( ) ;
new A( ).modify( ) ;
new B( ).modify( ) ; 

• test it here

You will notice a few changes.

Most importantly the call to the supposed "super-classes" constructor is now implicit within this line:

<name>.prototype = new C ;

Both A and B will now have individually modifiable members x and y which would not be the case if we would have written ... = C instead.

Then, x, y and modify are all "public" members so that assigning a different Function to them

 <name>.prototype.modify = function( ) { /* ... */ }

will "override" the original Function by that name.

Lastly, the call to modify cannot be done in the Function declaration because the implicit call to the "super-class" would then be executed again when we set the supposed "super-class" to the prototype property of the supposed "sub-classes".

But well, this is more or less how you would do this kind of thing in JavaScript.

HTH,

it is also possible to implement what you want using a single layer

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >

    <item
        android:bottom="-5dp"
        android:right="-5dp"
        android:top="-5dp">
        <shape android:shape="rectangle" >
            <solid android:color="@color/color_of_the_background" />

            <stroke
                android:width="5dp"
                android:color="@color/color_of_the_border" />
        </shape>
    </item>

</layer-list>

this way only left border is visible but you can achieve any combination you want by playing with bottom, left, right and top attributes of the item element

The answer of Jari Laamanen is the best solution. I want just explain how to use more than 1 input parameter with shell variables:

output=test1.png
data=foo.data
gnuplot -e "datafile='${data}'; outputname='${output}'" foo.plg

and foo.plg:

set terminal png
set outputname 
f(x) = sin(x)
plot datafile

As you can see,more parameters are passed with semi colons (like in bash scripts), but string variables NEED to be encapsuled with ' ' (gnuplot syntax, NOT Bash syntax)

audio /= np.max(np.abs(audio),axis=0)
image *= (255.0/image.max())

Using /= and *= allows you to eliminate an intermediate temporary array, thus saving some memory. Multiplication is less expensive than division, so

image *= 255.0/image.max()    # Uses 1 division and image.size multiplications

is marginally faster than

image /= image.max()/255.0    # Uses 1+image.size divisions

Since we are using basic numpy methods here, I think this is about as efficient a solution in numpy as can be.

In-place operations do not change the dtype of the container array. Since the desired normalized values are floats, the audio and image arrays need to have floating-point point dtype before the in-place operations are performed. If they are not already of floating-point dtype, you'll need to convert them using astype. For example,

image = image.astype('float64')

java.lang.ClassCastException: [Ljava.lang.Object; cannot be cast to [Ljava.lang.Integer;

you try to cast an Array of Object to cast into Array of Integer. You cant do it. This type of downcast is not permitted.

You can make an array of Integer, and after that copy every value of the first array into second array.

This is typically done using an edit distance measure. Searching for "edit distance java" turns up a number of libraries, like this one.

Alternatively, you can use requests.Session and observe cookies before and after a request:

>>> import requests
>>> session = requests.Session()
>>> print(session.cookies.get_dict())
{}
>>> response = session.get('http://google.com')
>>> print(session.cookies.get_dict())
{'PREF': 'ID=5514c728c9215a9a:FF=0:TM=1406958091:LM=1406958091:S=KfAG0U9jYhrB0XNf', 'NID': '67=TVMYiq2wLMNvJi5SiaONeIQVNqxSc2RAwVrCnuYgTQYAHIZAGESHHPL0xsyM9EMpluLDQgaj3db_V37NjvshV-eoQdA8u43M8UwHMqZdL-S2gjho8j0-Fe1XuH5wYr9v'}

Rather than:

first_element = myList[i[0]]

You probably want:

first_element = myList[i][0]

I'd love to use regex to accomplish this, but since you can only use lists, loops, functions, etc..

here's what I came up with:

stringWithNumbers="I have 10 bananas for my 5 monkeys!"
stringWithoutNumbers=''.join(c if c not in map(str,range(0,10)) else "" for c in stringWithNumbers)
print(stringWithoutNumbers) #I have  bananas for my  monkeys!

Select value from drop down.

  <select class="form-control" name="category" id="sel1">
                   <?php         
                    foreach($data as $key =>$value){ 
                      ?>                         
                           <option value="<?php echo $data[$key]->name; ?>"<?php if($id_name[0]->p_name==$data[$key]->name) echo 'selected="selected"'; ?>><?php echo $data[$key]->name; ?></option>
                    <?php } ?>
   </select> 

In addition to this solution (https://stackoverflow.com/a/3727813/5218712) just want to add that it should work only if listView.getChildCount() == yourDataList.size(); There could be additional view inside ListView.

Example of how the child elements are populated:

I am sure what Artem Bilan has explained here might be one of the reasons for this error:

Caused by: com.rabbitmq.client.AuthenticationFailureException: 
ACCESS_REFUSED - Login was refused using authentication mechanism PLAIN. 
For details see the

but the solution for me was that I logged in to rabbitMQ admin page (http://localhost:15672/#/users) with the default user name and password which is guest/guest then added a new user and for that new user I enabled the permission to access it from virtual host and then used the new user name and password instead of default guest and that cleared the error.

In the spring framework, there is an annotation called the repository, and in the description of this annotation, there is useful information about the repository, which I think it is useful for this discussion.

Indicates that an annotated class is a "Repository", originally defined by Domain-Driven Design (Evans, 2003) as "a mechanism for encapsulating storage, retrieval, and search behavior which emulates a collection of objects".

Teams implementing traditional Java EE patterns such as "Data Access Object" may also apply this stereotype to DAO classes, though care should be taken to understand the distinction between Data Access Object and DDD-style repositories before doing so. This annotation is a general-purpose stereotype and individual teams may narrow their semantics and use as appropriate.

A class thus annotated is eligible for Spring DataAccessException translation when used in conjunction with a PersistenceExceptionTranslationPostProcessor. The annotated class is also clarified as to its role in the overall application architecture for the purpose of tooling, aspects, etc.

You can add your own id or class to the body tag of your index page to target all elements on that page with a custom style like so:

<body id="index">
   <h1>...</h1>
</body>

Then you can target the elements you wish to modify with your class or id like so:

#index h1 {
   color:red;
}

The rebinding behaviour mentioned in other answers does matter in certain circumstances:

>>> a = ([],[])
>>> a[0].append(1)
>>> a
([1], [])
>>> a[1] += [1]
Traceback (most recent call last):
  File "<interactive input>", line 1, in <module>
TypeError: 'tuple' object does not support item assignment

That's because augmented assignment always rebinds, even if the object was mutated in-place. The rebinding here happens to be a[1] = *mutated list*, which doesn't work for tuples.

You're trying to pass file objects as filenames. Try using

infile = '110331_HS1A_1_rtTA.result'
outfile = '2.txt'

at the top of your code.

(Not only does the doubled usage of open() cause that problem with trying to open the file again, it also means that infile and outfile are never closed during the course of execution, though they'll probably get closed once the program ends.)

This error is happening because you are just opening html documents directly from the browser. To fix this you will need to serve your code from a webserver and access it on localhost. If you have Apache setup, use it to serve your files. Some IDE's have built in web servers, like JetBrains IDE's, Eclipse...

If you have Node.Js setup then you can use http-server. Just run npm install http-server -g and you will be able to use it in terminal like http-server C:\location\to\app. Kirill Fuchs

Actually its pretty easy to make integration between Csharp (VS) and Python with IronPython. It's not that much complex... As Chris Dunaway already said in answer section I started to build this inegration for my own project. N its pretty simple. Just follow these steps N you will get your results.

step 1 : Open VS and create new empty ConsoleApp project.

step 2 : Go to tools --> NuGet Package Manager --> Package Manager Console.

step 3 : After this open this link in your browser and copy the NuGet Command. Link: https://www.nuget.org/packages/IronPython/2.7.9

step 4 : After opening the above link copy the PM>Install-Package IronPython -Version 2.7.9 command and paste it in NuGet Console in VS. It will install the supportive packages.

step 5 : This is my code that I have used to run a .py file stored in my Python.exe directory.

using IronPython.Hosting;//for DLHE
using Microsoft.Scripting.Hosting;//provides scripting abilities comparable to batch files
using System;
using System.Diagnostics;
using System.IO;
using System.Net;
using System.Net.Sockets;
class Hi
{
private static void Main(string []args)
{
Process process = new Process(); //to make a process call
ScriptEngine engine = Python.CreateEngine(); //For Engine to initiate the script
engine.ExecuteFile(@"C:\Users\daulmalik\AppData\Local\Programs\Python\Python37\p1.py");//Path of my .py file that I would like to see running in console after running my .cs file from VS.//process.StandardInput.Flush();
process.StandardInput.Close();//to close
process.WaitForExit();//to hold the process i.e. cmd screen as output
}
} 

step 6 : save and execute the code

I would like to add something to the responses that I read in this thread and this thread (which references this one).

Disclaimer: this remarks come from the experiments I ran

Variables outside __init__:

These are, in fact, static class variables and are, therefore, accesible to all instances of the class.

Variables inside __init__:

The value of these instance variables are only accesible to the instance at hand (through the self reference)

My contribution:

One thing that programmers must consider when using static class variables is that they can be shadowed by instance variables (if you are accessing the static class variables through the self reference).

Explanation:

Previously, I thought that both ways of declaring the variables were exactly the same (silly me), and that was partly because I could access both kind of variables through the self reference. It was now, when I ran into trouble, that I researched the topic and cleared it up.

The problem with accessing static class variables through the self reference is that it only references the static class variable if there is no instance variable with the same name, and to make things worse, trying to redefine a static class variable through the self reference does not work because an instance variable is created which then shadows the previously-accesible static class variable.

To get around this problem, you should always reference static class variables through the name of the class.

Example:

#!/usr/bin/env python

class Foo:
    static_var = 'every instance has access'

    def __init__(self,name):
        self.instance_var = 'I am %s' % name

    def printAll(self):
        print 'self.instance_var = %s' % self.instance_var
        print 'self.static_var = %s' % self.static_var
        print 'Foo.static_var = %s' % Foo.static_var

f1 = Foo('f1')

f1.printAll()

f1.static_var = 'Shadowing static_var'

f1.printAll()

f2 = Foo('f2')

f2.printAll()

Foo.static_var = 'modified class'

f1.printAll()
f2.printAll()

Output:

self.instance_var = I am f1
self.static_var = every instance has access
Foo.static_var = every instance has access
self.instance_var = I am f1
self.static_var = Shadowing static_var
Foo.static_var = every instance has access
self.instance_var = I am f2
self.static_var = every instance has access
Foo.static_var = every instance has access
self.instance_var = I am f1
self.static_var = Shadowing static_var
Foo.static_var = modified class
self.instance_var = I am f2
self.static_var = modified class
Foo.static_var = modified class

I hope this is helpful to someone

On Django 1.9, I tried django-admin runserver and got the same error, but when I used python manage.py runserver I got the intended result. This may solve this error for a lot of people!

1. Right click on your /bat/ folder and click Create Shortcut.

   • On Windows 7 you will get bat - Shortcut in the current directory.
   • On Windows XP you will get Shortcut to bat.

2. Right click on the shortcut you just created and click Properties.

3. Change Target (under the Shortcut tab on Windows 7) to the following:

   %windir%\system32\cmd.exe /c start "" "%CD%\bat\bat\run.bat"
   

4. Make sure Start in is blank. That causes it to start in the current directory.

5. Click OK. On Windows 7, the shortcut icon will change to the cmd.exe icon.

6. That's probably acceptable in the case of shortcutting to a .bat but if you want to change the icon, open the shortcut's properties again and click Change Icon... (again, under the Shortcut tab on Windows 7). At this point you can Browse... for an icon or bring up a list of default system icons by entering

   %SystemRoot%\system32\SHELL32.dll
   

   to the left of the Browse... button and hitting Enter. This works on Windows 7 and Windows XP but the icons are different due to style updates (but are recognizably similar). Depending on the version of Windows the shortcut resides, the icon will will sometimes change accordingly.

More Info:

See Using the "start" command with parameters passed to the started program to better understand the empty double-quotes at the beginning of the first Target command.

There is no system defined function in SQL server. But you can create your own user-defined function- a scalar function. You would find scalar functions in the Object Explorer for your database: Programmability->Functions->Scalar-valued Functions. Below, I use a table variable to bring it all together.

--Create the user-defined function
CREATE FUNCTION getmonth (@num int)
RETURNS varchar(9) --since 'September' is the longest string, length 9
AS
BEGIN

DECLARE @intMonth Table (num int PRIMARY KEY IDENTITY(1,1), month varchar(9))

INSERT INTO @intMonth VALUES ('January'), ('February'), ('March'), ('April'), ('May')
                           , ('June'), ('July'), ('August') ,('September'), ('October')
                           , ('November'), ('December')

RETURN (SELECT I.month
        FROM @intMonth I
        WHERE I.num = @num)
END
GO

--Use the function for various months
SELECT dbo.getmonth(4) AS [Month]
SELECT dbo.getmonth(5) AS [Month]
SELECT dbo.getmonth(6) AS [Month]

I had same problem, but I think I have simple solution(code is from my RoR app): Extract industry ids from yahoo.finance.sectors and add it to db:

    select = "select * from yahoo.finance.sectors"
    generate_query select
    @data.each do |data|
      data["industry"].each do |ind|
        unless ind.kind_of?(Array)
          unless ind["id"].nil?
            id = ind["id"].to_i
            if id > 0
              Industry.where(id: id).first_or_create(name: ind["name"]).update_attribute(:name, ind["name"])
            end
          end
        end
      end
    end

Extract all comanies with their symbols with industry ids:

    ids = Industry.all.map{|ind| "'#{ind.id.to_s}'" }.join(",")
    select = "select * from yahoo.finance.industry where id in"
    generate_query select, ids
    @data.each do |ts|
      unless ts.kind_of?(Array) || ts["company"].nil?
        if ts["company"].count == 2 && ts["company"].first[0] == "name"
          t = ts["company"]
          Ticket.find_or_create_by_symbol(symbol: t["symbol"], name: t["name"] ).update_attribute(:name, t["name"])
        else
          ts["company"].each do |t|
            Ticket.find_or_create_by_symbol(symbol: t["symbol"], name: t["name"] ).update_attribute(:name, t["name"])

IMPORTANT NOTE: You should not concatenate SQL queries unless you trust the user completely. Query concatenation involves risk of SQL Injection being used to take over the world, ...khem, your database.

If you don't want to go into details how to execute query using SqlCommand then you could call the same command line like this:

string userInput = "Brian";
var process = new Process();
var startInfo = new ProcessStartInfo();
startInfo.WindowStyle = ProcessWindowStyle.Hidden;
startInfo.FileName = "cmd.exe";
startInfo.Arguments = string.Format(@"sqlcmd.exe -S .\PDATA_SQLEXPRESS -U sa -P 2BeChanged! -d PDATA_SQLEXPRESS  
     -s ; -W -w 100 -Q "" SELECT tPatCulIntPatIDPk, tPatSFirstname, tPatSName,
     tPatDBirthday  FROM  [dbo].[TPatientRaw] WHERE tPatSName = '{0}' """, userInput);

process.StartInfo = startInfo;
process.Start();

Just ensure that you escape each double quote " with ""

What I think you may want is an ArrayList<Integer> instead of an array. This will allow you do to:

ArrayList<Integer> arr = new ArrayList<Integer>(20);
System.out.println(arr.size());

The output will be 0.

Then, you can add things to the list, and it will keep track of the count for you. (It will also grow the size of the backing storage as you need as well.)

.NET Framework provides many collection classes too. You can use Dictionary in C#. Please find the below msdn link for details and samples http://msdn.microsoft.com/en-us/library/xfhwa508.aspx

Suppose the directory is present in C:/harley/mydir. What you have to do is the following:

• Create a new project (Right click on Project explorer, select New -> Project; from the wizard list, select General -> Project and click next.)

• Give to the project the same name of your target directory (in this case mydir)

• Uncheck Use default location and give the exact location, for example C:/harley/mydir

• Click on Finish

You are done. I do it this way.

select min(DEPARTMENT.DeptName) as deptname 
from DEPARTMENT
inner join employee on
DEPARTMENT.DeptId = employee.DeptId
where Salary > 1000
group by (EmpId) having count(EmpId) > =2 

FYI, I needed to update the color of the calendar icon which didn't seem possible with properties like color, fill, etc.

I did eventually figure out that some filter properties will adjust the icon so while i did not end up figuring out how to make it any color, luckily all I needed was to make it so the icon was visible on a dark background so I was able to do the following:

body { background: black; }_x000D_
_x000D_
input[type="date"] { _x000D_
  background: transparent;_x000D_
  color: white;_x000D_
}_x000D_
_x000D_
input[type="date"]::-webkit-calendar-picker-indicator {_x000D_
  filter: invert(100%);_x000D_
}

<body>_x000D_
 <input type="date" />_x000D_
</body>

Hopefully this helps some people as for the most part chrome even directly says this is impossible.

please try to make it as a character

string str = "Tigger";
//then str[0] will return 'T' not "T"

What will you have? You'll probably end up with a default search and a search that you load from somewhere. Default search requires a default constructor, so make one like Dismissile has already suggested.

If you load the search criteria from elsewhere, then you should probably have some mapping logic.

I have observed this once when running the application inside the emulator. In the emulator settings, you need to specify the size of external storage ("SD Card") properly. By default, the "external storage" field is empty, and that probably means there is no such device and EACCES is thrown even if permissions are granted in the manifest.

No you can't use case and in like this. But you can do

SELECT * FROM Product P    
WHERE @Status='published' and P.Status IN (1,3)
or @Status='standby' and P.Status IN  (2,5,9,6)
or @Status='deleted' and P.Status IN (4,5,8,10)
or P.Status IN (1,3)

BTW you can reduce that to

SELECT * FROM Product P    
WHERE @Status='standby' and P.Status IN (2,5,9,6)
or @Status='deleted' and P.Status IN (4,5,8,10)
or P.Status IN (1,3)

since or P.Status IN (1,3) gives you also all records of @Status='published' and P.Status IN (1,3)

Every method in HtmlHelper class has a twin with For suffix. Html.Hidden takes a string as an argument that you must provide but Html.HiddenFor takes an Expression that if you view is a strongly typed view you can benefit from this and feed that method a lambda expression like this

o=>o.SomeProperty 

instead of "SomeProperty" in the case of using Html.Hidden method.

you can convert this string into an array of chars using split(), then iterate through it.

const str = "javascript";_x000D_
const strArray = str.split('');_x000D_
_x000D_
strArray.map(s => console.log(s));

If your repo have 2FA enabled. Highly suggest to use the app provided by github.com Here is the link: https://desktop.github.com/

After you downloaded it and installed it. Follow the withard, the app will ask you to provide the one time password for login. Once you filled in the one time password, you could see your repo/projects now.

That's funny you asked this, I just did this recently for my work's site and I was thinking I should write a tutorial... Here is how to do it with PHP/Imagick, which uses ImageMagick:

$usmap = '/path/to/blank/us-map.svg';
$im = new Imagick();
$svg = file_get_contents($usmap);

/*loop to color each state as needed, something like*/ 
$idColorArray = array(
     "AL" => "339966"
    ,"AK" => "0099FF"
    ...
    ,"WI" => "FF4B00"
    ,"WY" => "A3609B"
);

foreach($idColorArray as $state => $color){
//Where $color is a RRGGBB hex value
    $svg = preg_replace(
         '/id="'.$state.'" style="fill:#([0-9a-f]{6})/'
        , 'id="'.$state.'" style="fill:#'.$color
        , $svg
    );
}

$im->readImageBlob($svg);

/*png settings*/
$im->setImageFormat("png24");
$im->resizeImage(720, 445, imagick::FILTER_LANCZOS, 1);  /*Optional, if you need to resize*/

/*jpeg*/
$im->setImageFormat("jpeg");
$im->adaptiveResizeImage(720, 445); /*Optional, if you need to resize*/

$im->writeImage('/path/to/colored/us-map.png');/*(or .jpg)*/
$im->clear();
$im->destroy();

the steps regex color replacement may vary depending on the svg path xml and how you id & color values are stored. If you don't want to store a file on the server, you can output the image as base 64 like

<?php echo '<img src="data:image/jpg;base64,' . base64_encode($im) . '"  />';?>

(before you use clear/destroy) but ie has issues with PNG as base64 so you'd probably have to output base64 as jpeg

you can see an example here I did for a former employer's sales territory map:

Start: https://upload.wikimedia.org/wikipedia/commons/1/1a/Blank_US_Map_(states_only).svg

Finish:

Edit

Since writing the above, I've come up with 2 improved techniques:

1) instead of a regex loop to change the fill on state , use CSS to make style rules like

<style type="text/css">
#CA,#FL,HI{
    fill:blue;
}
#Al, #NY, #NM{
    fill:#cc6699;
}
/*etc..*/
</style>

and then you can do a single text replace to inject your css rules into the svg before proceeding with the imagick jpeg/png creation. If the colors don't change, check to make sure you don't have any inline fill styles in your path tags overriding the css.

2) If you don't have to actually create a jpeg/png image file (and don't need to support outdated browsers), you can manipulate the svg directly with jQuery. You can't access the svg paths when embedding the svg using img or object tags, so you'll have to directly include the svg xml in your webpage html like:

<div>
<?php echo file_get_contents('/path/to/blank/us-map.svg');?>
</div>

then changing the colors is as easy as:

<script type="text/javascript" src="/path/to/jquery.js"></script>
<script type="text/javascript">
    $('#CA').css('fill', 'blue');
    $('#NY').css('fill', '#ff0000');
</script>

A solution, can be:

with open("file", "r") as fd:
    lines = fd.read().splitlines()

You get the list of lines without "\r\n" or "\n".

Or, use the classic way:

with open("file", "r") as fd:
    for line in fd:
        line = line.strip()

You read the file, line by line and drop the spaces and newlines.

If you only want to drop the newlines:

with open("file", "r") as fd:
    for line in fd:
        line = line.replace("\r", "").replace("\n", "")

Et voilà.

Note: The behavior of Python 3 is a little different. To mimic this behavior, use io.open.

See the documentation of io.open.

So, you can use:

with io.open("file", "r", newline=None) as fd:
    for line in fd:
        line = line.replace("\n", "")

When the newline parameter is None: lines in the input can end in '\n', '\r', or '\r\n', and these are translated into '\n'.

newline controls how universal newlines works (it only applies to text mode). It can be None, '', '\n', '\r', and '\r\n'. It works as follows:

On input, if newline is None, universal newlines mode is enabled. Lines in the input can end in '\n', '\r', or '\r\n', and these are translated into '\n' before being returned to the caller. If it is '', universal newlines mode is enabled, but line endings are returned to the caller untranslated. If it has any of the other legal values, input lines are only terminated by the given string, and the line ending is returned to the caller untranslated.

If in the listener you get the root layout of the item (say itemLayout), and you gave some id's to the textviews, you can then get them with something like itemLayout.findViewById(R.id.textView1).

I actually used the answer from How do I run a node.js app as a background service? combined with what dwrz said above. In my case, I was creating a Discord bot that needed to be able to run when I was not around.

With this service in place, I initially got the same error that the initial poster did, which brought me here. I was missing the #!/usr/bin/env node at the top of my executed node.js script.

Since then, no problems, although I intend to see what else can be extended to the service itself.

Yes, it can be done.
It is based on the new html5 "download" attribute of anchor tags.
The flow should be something like this :

1. load the image
2. draw the image into a canvas with the crop boundaries specified
3. get the image data from the canvas and make it a href attribute for an anchor tag in the dom
4. add the download attribute (download="desired-file-name") to that a element That's it. all the user has to do is click your "download link" and the image will be downloaded to his pc.

I'll come back with a demo when I get the chance.

Update
Here's the live demo as I promised. It takes the jsfiddle logo and crops 5px of each margin.
The code looks like this :

var img = new Image();
img.onload = function(){
    var cropMarginWidth = 5,
        canvas = $('<canvas/>')
                    .attr({
                         width: img.width - 2 * cropMarginWidth,
                         height: img.height - 2 * cropMarginWidth
                     })
                    .hide()
                    .appendTo('body'),
        ctx = canvas.get(0).getContext('2d'),
        a = $('<a download="cropped-image" title="click to download the image" />'),
        cropCoords = {
            topLeft : {
                x : cropMarginWidth,
                y : cropMarginWidth 
            },
            bottomRight :{
                x : img.width - cropMarginWidth,
                y : img.height - cropMarginWidth
            }
        };

    ctx.drawImage(img, cropCoords.topLeft.x, cropCoords.topLeft.y, cropCoords.bottomRight.x, cropCoords.bottomRight.y, 0, 0, img.width, img.height);
    var base64ImageData = canvas.get(0).toDataURL();


    a
        .attr('href', base64ImageData)
        .text('cropped image')
        .appendTo('body');

    a
        .clone()
        .attr('href', img.src)
        .text('original image')
        .attr('download','original-image')
        .appendTo('body');

    canvas.remove();
}
img.src = 'some-image-src';

Update II
Forgot to mention : of course there is a downside :(.
Because of the same-origin policy that is applied to images too, if you want to access an image's data (through the canvas method toDataUrl).
So you would still need a server-side proxy that would serve your image as if it were hosted on your domain.

Update III Although I can't provide a live demo for this (for security reasons), here is a php sample code that solves the same-origin policy :

file proxy.php :

$imgData = getimagesize($_GET['img']);
header("Content-type: " . $imgData['mime']);
echo file_get_contents($_GET['img']);  

This way, instead of loading the external image direct from it's origin :

img.src = 'http://some-domain.com/imagefile.png';

You can load it through your proxy :

img.src = 'proxy.php?img=' + encodeURIComponent('http://some-domain.com/imagefile.png');  

And here's a sample php code for saving the image data (base64) into an actual image :

file save-image.php :

$data = preg_replace('/data:image\/(png|jpg|jpeg|gif|bmp);base64/','',$_POST['data']);
$data = base64_decode($data);
$img = imagecreatefromstring($data);

$path = 'path-to-saved-images/';
// generate random name
$name  = substr(md5(time()),10);
$ext = 'png';
$imageName = $path.$name.'.'.$ext;

// write the image to disk
imagepng($img,  $imageName);
imagedestroy($img);
// return the image path
echo $imageName;

All you have to do then is post the image data to this file and it will save the image to disc and return you the existing image filename.

Of course all this might feel a bit complicated, but I wanted to show you that what you're trying to achieve is possible.

In your pg_hba.conf file, I see some incorrect and confusing lines:

# fine, this allows all dbs, all users, to be trusted from 192.168.0.1/32
# not recommend because of the lax permissions
host    all        all         192.168.0.1/32        trust

# wrong, /128 is an invalid netmask for ipv4, this line should be removed
host    all        all         192.168.0.1/128       trust

# this conflicts with the first line
# it says that that the password should be md5 and not plaintext
# I think the first line should be removed
host    all        all         192.168.0.1/32        md5

# this is fine except is it unnecessary because of the previous line
# which allows any user and any database to connect with md5 password
host    chaosLRdb  postgres    192.168.0.1/32        md5

# wrong, on local lines, an IP cannot be specified
# remove the 4th column
local   all        all         192.168.0.1/32        trust

I suspect that if you md5'd the password, this might work if you trim the lines. To get the md5 you can use perl or the following shell script:

 echo -n 'chaos123' | md5sum
 > d6766c33ba6cf0bb249b37151b068f10  -

So then your connect line would like something like:

my $dbh = DBI->connect("DBI:PgPP:database=chaosLRdb;host=192.168.0.1;port=5433",
    "chaosuser", "d6766c33ba6cf0bb249b37151b068f10");

For more information, here's the documentation of postgres 8.X's pg_hba.conf file.

You usually see it in the ternary assignment operator;

Syntax

variable =  `condition ? result 1 : result 2;`

example:

boolean isNegative = number > 0 ? false : true;

which is "equivalent" in nature to the if else

if(number > 0){
    isNegative = false;
}
else{
    isNegative = true;
}

Other than examples given by different posters,

you can also use : to signify a label for a block which you can use in conjunction with continue and break..

for example:

public void someFunction(){
     //an infinite loop
     goBackHere: { //label
          for(int i = 0; i < 10 ;i++){
               if(i == 9 ) continue goBackHere;
          }
     }
}

Since the question was asking how to do this with JS I'm providing a vanilla JS implementation.

var element = document.querySelector(".your-element-class-goes-here");
// it's a good idea to check whether the element exists
if (element != null && element != undefined) {
  element.disabled = "disabled";
}

Well I have been battling to understand why, when at the Account section of the installation of a second node, the system will not accept the password I used to log in. I have been scratching my head - reading every post under the sun all to no avail.

I did notice that some service accounts were given as [email protected] and others were given as DOMAIN\service.instname.instno (the latter being the Win2000 version)

I also noticed comments about strength of password so I thought - I can do that so I changed the password to a much higher strength and RDC in to the server - with new password and thought - best to update the services on the existing node first. I stopped the service, clicked on password and pasted in from the clipboard - (can't go wrong eh?) ha ha says Windows.. Got ya.. it wouldn't accept the password - that I just logged in with. I clicked on browse to select the service account and VOILA! the account name changed to the DOMAIN\user version and readily accepted the password. I then repeated the exercise on the other service. I then found that the node installation would continue (after backing up and forward through the process) to pick up the new name format and accepted the passwords without complaint.

I think the moral of this experience is to use the wizards and select through the "browse" button rather than manually entering the service name.

I hope my experience saves someone else the pain I went through.

You can use Path.Combine with the "base" path, then GetFullPath on the results.

string absPathContainingHrefs = GetAbsolutePath(); // Get the "base" path
string fullPath = Path.Combine(absPathContainingHrefs, @"..\..\images\image.jpg");
fullPath = Path.GetFullPath(fullPath);  // Will turn the above into a proper abs path

To improve James' excellent answer:

It's better to put BINARY in front of the constant instead:

SELECT * FROM `table` WHERE `column` = BINARY 'value'

Putting BINARY in front of column will prevent the use of any index on that column.

new URL("file:///your/file/here")

To those still having problems, I solved it this way:

List<Item> newItems = databaseHandler.getItems();
ListArrayAdapter.clear();
ListArrayAdapter.addAll(newItems);
ListArrayAdapter.notifyDataSetChanged();
databaseHandler.close();

I first cleared the data from the adapter, then added the new collection of items, and only then set notifyDataSetChanged(); This was not clear for me at first, so I wanted to point this out. Take note that without calling notifyDataSetChanged() the view won't be updated.

I take that to my app.module. After the imports it should be works

I prefer to hunt down and fix problems instead of suppressing logs whenever possible. After a couple days of observing this issue in my app, I realized I was setting listeners on the req.socket in an Express middleware to catch socket io errors that kept popping up. At some point, I learned that that was not necessary, but I kept the listeners around anyway. I just removed them and the error you are experiencing went away. I verified it was the cause by running requests to my server with and without the following middleware:

socketEventsHandler(req, res, next) {
        req.socket.on("error", function(err) {
            console.error('------REQ ERROR')
            console.error(err.stack)
        });
        res.socket.on("error", function(err) {
            console.error('------RES ERROR')
            console.error(err.stack)
        });
        next();
    }

Removing that middleware stopped the warning you are seeing. I would look around your code and try to find anywhere you may be setting up listeners that you don't need.

    // Single quotes
    echo 'My name is $fname.'; // My name is $fname.

    // Double quotes
    echo "My name is $fname."; // My name is David.

    // Curly braces to isolate the name of the variable
    echo "My name is {$fname}."; // My name is David.

set -x enables a mode of the shell where all executed commands are printed to the terminal. In your case it's clearly used for debugging, which is a typical use case for set -x: printing every command as it is executed may help you to visualize the control flow of the script if it is not functioning as expected.

set +x disables it.

return $picName = time().'.'.$request->file->extension();

The time() function will make the image unique then the .$request->file->extension() gets the image extension for you.

You can use this it works well with Laravel 6 and above.

If you're looking for reflection of all properties, the answers above are great.

If you're simply looking to get the keys of a dictionary (which is different from an 'object' in Python), use

my_dict.keys()

my_dict = {'abc': {}, 'def': 12, 'ghi': 'string' }
my_dict.keys() 
> ['abc', 'def', 'ghi']

You are thinking in the right direction. Merge master with mobiledevicesupport continuously and merge mobiledevicesupport with master when mobiledevicesupport is stable. Each developer will have his own branch and can merge to and from either on master or mobiledevicesupport depending on their role.

As RocketDonkey suggested, your module itself needs to have some docstrings.

For example, in myModule/__init__.py:

"""
The mod module
"""

You'd also want to generate documentation for each file in myModule/*.py using

pydoc myModule.thefilename

to make sure the generated files match the ones that are referenced from the main module documentation file.

Minor update on top of Karthik Bose's answer - you can configure git globally, to affect all of your workspaces to behave that way:

git config --global push.default upstream

Dot notation does not work with some keywords (like new and class) in internet explorer 8.

I had this code:

//app.users is a hash
app.users.new = {
  // some code
}

And this triggers the dreaded "expected indentifier" (at least on IE8 on windows xp, I havn't tried other environments). The simple fix for that is to switch to bracket notation:

app.users['new'] = {
  // some code
}

Adding this first conditional should work:

protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
    if(resultCode != RESULT_CANCELED){
        if (requestCode == CAMERA_REQUEST) {  
            Bitmap photo = (Bitmap) data.getExtras().get("data"); 
            imageView.setImageBitmap(photo);
        }
    }
}

I recommend Google protocol buffers. I had the chance to test drive the library on a new project and it's remarkably easy to use. The library is heavily optimized for performance.

Protobuf is different than other serialization solutions mentioned here in the sense that it does not serialize your objects, but rather generates code for objects that are serialization according to your specification.

You Should Used Collection keyword in Controller. Like Here..

public function ApiView(){
    return User::collection(Profile::all());
}

Here, User is Resource Name and Profile is Model Name. Thank You.

I was having the same problem and everyone was talking about this is related to DNS configuration, which make sense, since your container maybe isn't knowing how to resolve the name of the domain where your database is.

I guess your can configure that at the moment you start your container, but I think it's better to config this once and for all.

I'm using Windows 10 and in this case docker's gui give us some facilities.

Just right click on docker's icon in the tray bar and select "Settings" item.

Then, on the Docker's window, select the "Network" section and change the DNS option from "Automatic" to "Fixed" and hit "Apply". Docker will restart itself after that. I putted the Google's DNS (8.8.8.8) and it worked fine to me.

Hope it helps.

Just in case if the problem is still there, You can refer to ansible inventory through ‘hostvars’, ‘group_names’, and ‘groups’ ansible variables.

Example:

To be able to get ip addresses of all servers within group "mygroup", use the below construction:

- debug: msg="{{ hostvars[item]['ansible_eth0']['ipv4']['address'] }}" 
  with_items:
     - "{{ groups['mygroup'] }}"

Here is your simple and easy answer

Go to your class where you want to give a negative margin then copy and paste this inside the class.

Example for negative margin top

mt-n3

Example for negative margin bottom

mb-n2

You need to make sure requestAnimFrame stops being called once game == 1. A break statement only exits a traditional loop (e.g. while()).

function loop() {
    if (isPlaying) {
        jet1.draw();
        drawAllEnemies();
        if (game != 1) {
            requestAnimFrame(loop);
        }
    }
}

Or alternatively you could simply skip the second if condition and change the first condition to if (isPlaying && game !== 1). You would have to make a variable called game and give it a value of 0. Add 1 to it every game.

Try making the whole sheet font size smaller. Then zoom and save. Make a practice sheet first because it really screws everything up.

Unfortunately, (for practical and security reasons I guess), if you want to add/copy local content, it must be located under the same root path than the Dockerfile.

From the documentation:

The <src> path must be inside the context of the build; you cannot ADD ../something/something, because the first step of a docker build is to send the context directory (and subdirectories) to the docker daemon.

EDIT: There's now an option (-f) to set the path of your Dockerfile ; it can be used to achieve what you want, see @Boedy 's response.

I ran into the same problem. From my solution i came into this. So here is your code:

- root_directory
    - sub_directory_a
        - _common.scss
        - template.scss
    - sub_directory_b
        - more_styles.scss

As far i know if you want to import one scss to another its has to be a partial. When you are importing from different directory name your more_styles.scss to _more_styles.scss. Then import it into your template.scss like this @import ../sub_directory_b/_more_styles.scss. It worked for me. But as you mentioned ../sub_directory_a/_common.scss not working. That's the same directory of the template.scss. That is why it wont work.

Here is my implementation:

function daysBetween(one, another) {
  return Math.round(Math.abs((+one) - (+another))/8.64e7);
}

+<date> does the type coercion to the integer representation and has the same effect as <date>.getTime() and 8.64e7 is the number of milliseconds in a day.

package com.dataload;

    public class insertCSV 
    {
        public static void main(String args[])
        {
            ApplicationContext context =
        new ClassPathXmlApplicationContext("applicationcontext.xml");


            // retrieve configured instance
            JobLauncher launcher = context.getBean("laucher", JobLauncher.class);
            Job job = context.getBean("job", Job.class);
            JobParameters jobParameters = context.getBean("jobParameters", JobParameters.class);
        }
    }

use $BASHPID or $$

See the [manual][1] for more information, including differences between the two.

TL;DRTFM

• $$ Expands to the process ID of the shell.
  • In a () subshell, it expands to the process ID of the invoking shell, not the subshell.
• $BASHPID Expands to the process ID of the current Bash process (new to bash 4).
  • In a () subshell, it expands to the process ID of the subshell [1]: http://www.gnu.org/software/bash/manual/bashref.html#Bash-Variables

I don't think it is possible to share a database link between more than one user but not all. They are either private (for one user only) or public (for all users).

A good way around this is to create a view in SCHEMA_B that exposes the table you want to access through the database link. This will also give you good control over who is allowed to select from the database link, as you can control the access to the view.

Do like this:

create database link db_link... as before;
create view mytable_view as select * from mytable@db_link;
grant select on mytable_view to myuser;

After looking at the previous responses, I hope this will help resolve any ambiguities. In case the similarities in the previous solutions and my solution are illusive, or this method of solving for roots is unclear, I've also made a graph which can be found here.

This is a working root function capable of solving for any nth-root

(default is square root for the sake of this question)

#include <cmath> 
// for "pow" function

double sqrt(double A, double root = 2) {
    const double e = 2.71828182846;
    return pow(e,(pow(10.0,9.0)/root)*(1.0-(pow(A,-pow(10.0,-9.0)))));
}

Explanation:

click here for graph

This works via Taylor series, logarithmic properties, and a bit of algebra.

Take, for example:

log A = N
   x

*Note: for square-root, N = 2; for any other root you only need to change the one variable, N.

1) Change the base, convert the base 'x' log function to natural log,

log A   =>   ln(A)/ln(x) = N
   x

2) Rearrange to isolate ln(x), and eventually just 'x',

ln(A)/N = ln(x)

3) Set both sides as exponents of 'e',

e^(ln(A)/N) = e^(ln(x))  >~{ e^ln(x) == x }~>  e^(ln(A)/N) = x

4) Taylor series represents "ln" as an infinite series,

ln(x) = (k=1)Sigma: (1/k)(-1^(k+1))(k-1)^n

           <~~~ expanded ~~~>

[(x-1)] - [(1/2)(x-1)^2] + [(1/3)(x-1)^3] - [(1/4)(x-1)^4] + . . .

*Note: Continue the series for increased accuracy. For brevity, 10^9 is used in my function which expresses the series convergence for the natural log with about 7 digits, or the 10-millionths place, for precision,

ln(x) = 10^9(1-x^(-10^(-9)))

5) Now, just plug in this equation for natural log into the simplified equation obtained in step 3.

e^[((10^9)/N)(1-A^(-10^-9)] = nth-root of (A)

6) This implementation might seem like overkill; however, its purpose is to demonstrate how you can solve for roots without having to guess and check. Also, it would enable you to replace the pow function from the cmath library with your own pow function:

double power(double base, double exponent) {
    if (exponent == 0) return 1;
    int wholeInt = (int)exponent;
    double decimal = exponent - (double)wholeInt;
    if (decimal) {
        int powerInv = 1/decimal;
        if (!wholeInt) return root(base,powerInv);
        else return power(root(base,powerInv),wholeInt,true);
    }
    return power(base, exponent, true);
}

double power(double base, int exponent, bool flag) {
    if (exponent < 0) return 1/power(base,-exponent,true);
    if (exponent > 0) return base * power(base,exponent-1,true);
    else return 1;
}

int root(int A, int root) {
    return power(E,(1000000000000/root)*(1-(power(A,-0.000000000001))));
}

This worked for me in Angular 2:

var img = new Image()
img.src = 'assets/sample.png'
pdf.addImage(img, 'png', 10, 78, 12, 15)

jsPDF version 1.5.3

assets directory is in src directory of the Angular project root

For those like me that stumbled here looking for a viable solution to this issue, when the variable might be undefined, the closest i got is:

if 'variablename' in globals() and ((variablename or False) == True):
  print('variable exists and it\'s true')
else:
  print('variable doesn\'t exist, or it\'s false')

Note that a string is needed when checking in globals, but afterwards the actual variable is used when checking for value.

More on variable existence: How do I check if a variable exists?

To make @Mark Fisher's answer more clear, the inserted view being inflated should be a xml file under layout folder but without a layout (ViewGroup) like LinearLayout etc. inside. My example:

res/layout/my_view.xml

<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/i_am_id"
    android:text="my name"
    android:textSize="17sp"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_weight="1"/>

Then, the insertion point should be a layout like LinearLayout:

res/layout/activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/aaa"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <LinearLayout
        android:id="@+id/insert_point"
        android:layout_width="match_parent"
        android:layout_height="match_parent">

    </LinearLayout>

</RelativeLayout>

Then the code should be

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_shopping_cart);

    LayoutInflater inflater = getLayoutInflater();
    View view = inflater.inflate(R.layout.my_view, null);
    ViewGroup main = (ViewGroup) findViewById(R.id.insert_point);
    main.addView(view, 0);
}

The reason I post this very similar answer is that when I tried to implement Mark's solution, I got stuck on what xml file should I use for insert_point and the child view. I used layout in the child view firstly and it was totally not working, which took me several hours to figure out. So hope my exploration can save others' time.

Just for future reference:

I'm developing on iOS 6 using Storyboards.

I was having the same issue, but I could not find the "Identifier" field in the inspector. Instead, just set the field named "Storyboard ID" to what you would name the Identifier. This field can be found under the "Show the Identity inspector" tab in the inspector.

[Note - comments below indicate that some people have found that they need to (also?) set the field "Restoration ID" just below the Storyboard ID in the inspector. Clicking on "Use Storyboard ID" does not seem to be enough.]

There's an image below for reference: (in this instance I've named my identifier the same as my class)

If you happen to be using the venv module that comes with Python 3.3+, it supports an --upgrade option. Per the docs:

Upgrade the environment directory to use this version of Python, assuming Python has been upgraded in-place

python3 -m venv --upgrade ENV_DIR

You are looking for System.Reflection.Assembly.GetExecutingAssembly()

string assemblyFolder = Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location);
string xmlFileName = Path.Combine(assemblyFolder,"AggregatorItems.xml");

Note:

The .Location property returns the location of the currently running DLL file.

Under some conditions the DLL is shadow copied before execution, and the .Location property will return the path of the copy. If you want the path of the original DLL, use the Assembly.GetExecutingAssembly().CodeBase property instead.

.CodeBase contains a prefix (file:\), which you may need to remove.

For context, I created a project using the ASP.NET Core 2 Web Application template. Then, select the Web Application (MVC) then hit the Change Authentication button and select Individual User accounts.

There is a lot of infrastructure built up for you from this template. Find the ManageController in the Controllers folder.

This ManageController class constructor requires this UserManager variable to populated:

private readonly UserManager<ApplicationUser> _userManager;

Then, take a look at the the [HttpPost] Index method in this class. They get the current user in this fashion:

var user = await _userManager.GetUserAsync(User);

As a bonus note, this is where you want to update any custom fields to the user Profile you've added to the AspNetUsers table. Add the fields to the view, then submit those values to the IndexViewModel which is then submitted to this Post method. I added this code after the default logic to set the email address and phone number:

user.FirstName = model.FirstName;
user.LastName = model.LastName;
user.Address1 = model.Address1;
user.Address2 = model.Address2;
user.City = model.City;
user.State = model.State;
user.Zip = model.Zip;
user.Company = model.Company;
user.Country = model.Country;
user.SetDisplayName();
user.SetProfileID();

_dbContext.Attach(user).State = EntityState.Modified;
_dbContext.SaveChanges();

Two things you can do:

1. Change #childdivimage to a span element, and change #parentdivimage to an anchor tag. This may require you to add some more styling to get things looking perfect. This is preffered, since it uses semantic markup, and does not rely on javascript.

2. Use Javascript to bind a click event to #parentdivimage. You must redirect the browser window by modifying window.location inside this event. This is TheEasyWay^TM, but will not degrade gracefully.

For my project's setup, "${pageContext.request.contextPath}"= refers to "src/main/webapp". Another way to tell is by right clicking on your project in Eclipse and then going to Properties:

The first one should work:

> "a\nb".split("\n");
[ 'a', 'b' ]
> var a = "test.js\nagain.js"
undefined
> a.split("\n");
[ 'test.js', 'again.js' ]

DIFFERENCES - USES (when and why)

A field is a variable that is declared directly in a class or struct. A class or struct may have instance fields or static fields or both. Generally, you should use fields only for variables that have private or protected accessibility. Data that your class exposes to client code should be provided through methods, properties and indexers. By using these constructs for indirect access to internal fields, you can guard against invalid input values.

A property is a member that provides a flexible mechanism to read, write, or compute the value of a private field. Properties can be used as if they are public data members, but they are actually special methods called accessors. This enables data to be accessed easily and still helps promote the safety and flexibility of methods. Properties enable a class to expose a public way of getting and setting values, while hiding implementation or verification code. A get property accessor is used to return the property value, and a set accessor is used to assign a new value.

The best security practice is not to store the password at all (not even encrypted), but to store the salted hash (with a unique salt per password) of the encrypted password.

That way it is (practically) impossible to retrieve a plaintext password.

You can do:

SELECT GETDATE()+'03:30:00'

I couldn't just use the <xsl:text>&#xa;</xsl:text> approach because if I format the XML file using XSLT the entity will disappear. So I had to use a slightly more round about approach using variables

<xsl:variable name="nl" select="'&#10;'"/>
<xsl:template match="/">
    <xsl:value-of select="$nl" disable-output-escaping="no"/>
    <xsl:apply-templates select="*"/>
</xsl:template>

You can attach a SLOT to the

void aboutToQuit();

signal of your QApplication. This signal should be raised just before app closes.

This:

 lst = [8 for i in range(9)]

creates a list, elements are initialized 8

but this:

lst = [0] * 7

would create 7 lists which have one element

Try :

height: 21px;
line-height: 21px; /* FOR IE */

Because on some versions of IE (< 9) the property height is not properly interpreted.

In order to activate the core dump do the following:

1. In /etc/profile comment the line:

   # ulimit -S -c 0 > /dev/null 2>&1
   

2. In /etc/security/limits.conf comment out the line:

   *               soft    core            0
   

3. execute the cmd limit coredumpsize unlimited and check it with cmd limit:

   # limit coredumpsize unlimited
   # limit
   cputime      unlimited
   filesize     unlimited
   datasize     unlimited
   stacksize    10240 kbytes
   coredumpsize unlimited
   memoryuse    unlimited
   vmemoryuse   unlimited
   descriptors  1024
   memorylocked 32 kbytes
   maxproc      528383
   #
   

4. to check if the corefile gets written you can kill the relating process with cmd kill -s SEGV <PID> (should not be needed, just in case no core file gets written this can be used as a check):

   # kill -s SEGV <PID>
   

Once the corefile has been written make sure to deactivate the coredump settings again in the relating files (1./2./3.) !

If you are using Angular CLI: 7.3.3 What I did is, On my assets folder I put my fake json data then on my services I just did this.

const API_URL = './assets/data/db.json';

getAllPassengers(): Observable<PassengersInt[]> {
    return this.http.get<PassengersInt[]>(API_URL);
  }

In your generic method, T is just a placeholder for a type. However, the compiler doesn't per se know anything about the concrete type(s) being used runtime, so it can't assume that they will have a var member.

The usual way to circumvent this is to add a generic type constraint to your method declaration to ensure that the types used implement a specific interface (in your case, it could be ITest):

public void PrintGeneric<T>(T test) where T : ITest

Then, the members of that interface would be directly available inside the method. However, your ITest is currently empty, you need to declare common stuff there in order to enable its usage within the method.

Installing dev bits for mysql got rid of the config-win.h error I was having, and threw another. Failed to load and parse the manifest. The system cannot find the file specified. I found the answer to my problem in this post: http://www.fuyun.org/2009/12/install-mysql-for-python-on-windows/.

I copied the file 'C:\Python26\Lib\distutils\msvc9compiler.py` into my virtualenv, made the edit suggested in the above link, and things are working fine.

If you are making a cross-platform app (eg. using phonegap/cordova) then,

Don't use device-width or device-height. Rather use width or height in CSS media queries because Android device will give problems in device-width or device-height. For iOS it works fine. Only android devices doesn't support device-width/device-height.

Without external variables:

       $('.element').bind('mousewheel', function(e, d) {
            if((this.scrollTop === (this.scrollHeight - this.offsetHeight) && d < 0)
                || (this.scrollTop === 0 && d > 0)) {
                e.preventDefault();
            }
        });

After declaring correctly in pubspec.yaml, consider giving full path of the image ex.

'assets/images/about_us.png' 

instead of just images/..

worked for me after wasting 2 hours on such a trivial error.
