I had this issue while reloading data in UITableView. Simply dispatching reload as follows fixed the issue for me.

    dispatch_async(dispatch_get_main_queue(), { () -> Void in
        self.tableView.reloadData()
    })

What if your server goes down at 4:59AM and comes back at 5:01AM? I think it will just skip the run. I would recommend persistent scheduler like Quartz, that would store its schedule data somewhere. Then it will see that this run hasn't been performed yet and will do it at 5:01AM.

You should use fm element to delete blank spaces.

SELECT TO_CHAR(sysdate, 'fmDAY DD "de" MONTH "de" YYYY') CURRENT_DATE
FROM   dual;

For null values in the dataframe of pyspark

Dict_Null = {col:df.filter(df[col].isNull()).count() for col in df.columns}
Dict_Null

# The output in dict where key is column name and value is null values in that column

{'#': 0,
 'Name': 0,
 'Type 1': 0,
 'Type 2': 386,
 'Total': 0,
 'HP': 0,
 'Attack': 0,
 'Defense': 0,
 'Sp_Atk': 0,
 'Sp_Def': 0,
 'Speed': 0,
 'Generation': 0,
 'Legendary': 0}

I had the same issue too and this worked for me try:

this.http.request('http://thecatapi.com/api/images/get?format=html&results_per_page=10').
  subscribe((res) => {
    let resSTR = JSON.stringify(res);
    let resJSON = JSON.parse(resStr);
    console.log(resJSON._body);
  })

You'll need:

• Strong name your assembly (Visual Studio, Project Properties, Signing tab, Sign the assembly)
• Alter your Build Events (Project Properties, Build Events tab, Post-build command line)

   cd C:\Program Files\Microsoft Visual Studio 8\SDK\v2.0\Bin
   gacutil.exe /i "$(TargetPath)" /f /nologo
   gacutil /l "$(TargetName)" /nologo

Now, everytime you build your project, it'll be installed on GAC.

There isn't direct support for COUNT(DISTINCT {x})), but you can simulate it from an IGrouping<,> (i.e. what group by returns); I'm afraid I only "do" C#, so you'll have to translate to VB...

 select new
 {
     Foo= grp.Key,
     Bar= grp.Select(x => x.SomeField).Distinct().Count()
 };

Here's a Northwind example:

    using(var ctx = new DataClasses1DataContext())
    {
        ctx.Log = Console.Out; // log TSQL to console
        var qry = from cust in ctx.Customers
                  where cust.CustomerID != ""
                  group cust by cust.Country
                  into grp
                  select new
                  {
                      Country = grp.Key,
                      Count = grp.Select(x => x.City).Distinct().Count()
                  };

        foreach(var row in qry.OrderBy(x=>x.Country))
        {
            Console.WriteLine("{0}: {1}", row.Country, row.Count);
        }
    }

The TSQL isn't quite what we'd like, but it does the job:

SELECT [t1].[Country], (
    SELECT COUNT(*)
    FROM (
        SELECT DISTINCT [t2].[City]
        FROM [dbo].[Customers] AS [t2]
        WHERE ((([t1].[Country] IS NULL) AND ([t2].[Country] IS NULL)) OR (([t1]
.[Country] IS NOT NULL) AND ([t2].[Country] IS NOT NULL) AND ([t1].[Country] = [
t2].[Country]))) AND ([t2].[CustomerID] <> @p0)
        ) AS [t3]
    ) AS [Count]
FROM (
    SELECT [t0].[Country]
    FROM [dbo].[Customers] AS [t0]
    WHERE [t0].[CustomerID] <> @p0
    GROUP BY [t0].[Country]
    ) AS [t1]
-- @p0: Input NVarChar (Size = 0; Prec = 0; Scale = 0) []
-- Context: SqlProvider(Sql2008) Model: AttributedMetaModel Build: 3.5.30729.1

The results, however, are correct- verifyable by running it manually:

        const string sql = @"
SELECT c.Country, COUNT(DISTINCT c.City) AS [Count]
FROM Customers c
WHERE c.CustomerID != ''
GROUP BY c.Country
ORDER BY c.Country";
        var qry2 = ctx.ExecuteQuery<QueryResult>(sql);
        foreach(var row in qry2)
        {
            Console.WriteLine("{0}: {1}", row.Country, row.Count);
        }

With definition:

class QueryResult
{
    public string Country { get; set; }
    public int Count { get; set; }
}

Regarding tables names, case, etc, the prevalent convention is:

• SQL keywords: UPPER CASE
• names (identifiers): lower_case_with_underscores

For example:

UPDATE my_table SET name = 5;

This is not written in stone, but the bit about identifiers in lower case is highly recommended, IMO. Postgresql treats identifiers case insensitively when not quoted (it actually folds them to lowercase internally), and case sensitively when quoted; many people are not aware of this idiosyncrasy. Using always lowercase you are safe. Anyway, it's acceptable to use camelCase or PascalCase (or UPPER_CASE), as long as you are consistent: either quote identifiers always or never (and this includes the schema creation!).

I am not aware of many more conventions or style guides. Surrogate keys are normally made from a sequence (usually with the serial macro), it would be convenient to stick to that naming for those sequences if you create them by hand (tablename_colname_seq).

See also some discussion here, here and (for general SQL) here, all with several related links.

Note: Postgresql 10 introduced identity columns as an SQL-compliant replacement for serial.

Since jQuery doesn't support this out of the box, the best solution I have come across so far is to define your own CSS hooks in jQuery. Essentially, this means to define custom methods to get and set CSS values which also works with jQuery.animate().

There is already a very handy implementation for this on github: https://github.com/brandonaaron/jquery-cssHooks/blob/master/bgpos.js

With this plugin in place, you can do something like this:

$('#demo1').hover(
  function() {
    $(this).stop().animate({
      backgroundPositionX: '100%',
      backgroundPositionY: '100%'
    });
  },
  function () {
    $(this).stop().animate({
      backgroundPositionX: '105%',
      backgroundPositionY: '105%'
    });
  }
);

For me, this worked on all browsers tested so far including IE6+.

I did put a quick demo online a while ago and you can rip it apart if you need further guidance.

This is one of the biggest sources of confusion with VB.Net, IMO.

Nothing in VB.Net is the equivalent of default(T) in C#: the default value for the given type.

• For value types, this is essentially the equivalent of 'zero': 0 for Integer, False for Boolean, DateTime.MinValue for DateTime, ...
• For reference types, it is the null value (a reference that refers to, well, nothing).

The statement d Is Nothing is therefore equivalent to d Is DateTime.MinValue, which obviously does not compile.

Solutions: as others have said

• Either use DateTime? (i.e. Nullable(Of DateTime)). This is my preferred solution.
• Or use d = DateTime.MinValue or equivalently d = Nothing

In the context of the original code, you could use:

Dim d As DateTime? = Nothing
Dim boolNotSet As Boolean = d.HasValue

If you need to pass the asterisk symbol, you have to wrap it with quotes.

In my case, I need to configure cors for websockets. So, I decided to put cors urls into application.yml. For prod env I'll use specific urls, but for dev it's ok to use just *.

In yml file I have:

websocket:
  cors: "*"

In Config class I have:

@Value("${websocket.cors}")
private String[] cors;

You are implementing the Click Handler rather than Select Handler. A List by default doesn't suppose to have selection.

What you should change, in your above example, is to

public void onItemClick(AdapterView<?> adapter, View v, int position, long id) {
    MyClass item = (MyClass) adapter.getItem(position);
}

It's been quite some time but it's a core part of the stdlib and has dozens of potential methods so I think it's useful to have some benchmarks for the different suggestions and include the numpy method which can be by far the fastest.

import random
from timeit import timeit
import numpy as np

l = [random.random() for i in range(10**4)]
l[10**4 - 100] = 5

# method 1
def fun1(l:list, x:int, e = -1) -> int:
    return [[i for i,elem in enumerate(l) if elem == x] or [e]][0]

# method 2
def fun2(l:list, x:int, e = -1) -> int:
    for i,elem in enumerate(l):
        if elem == x:
            return i
    else:
        return e

# method 3
def fun3(l:list, x:int, e = -1) -> int:
    try:
        idx = l.index(x)
    except ValueError:
        idx = e
    return idx

# method 4
def fun4(l:list, x:int, e = -1) -> int:
    return l.index(x) if x in l else e

l2 = np.array(l)
# method 5
def fun5(l:list or np.ndarray, x:int, e = -1) -> int:
    res = np.where(np.equal(l, x))
    if res[0].any():
        return res[0][0]
    else:        
        return e


if __name__ == "__main__":
    print("Method 1:")
    print(timeit(stmt = "fun1(l, 5)", number = 1000, globals = globals()))
    print("")
    print("Method 2:")
    print(timeit(stmt = "fun2(l, 5)", number = 1000, globals = globals()))
    print("")
    print("Method 3:")
    print(timeit(stmt = "fun3(l, 5)", number = 1000, globals = globals()))
    print("")
    print("Method 4:")
    print(timeit(stmt = "fun4(l, 5)", number = 1000, globals = globals()))
    print("")
    print("Method 5, numpy given list:")
    print(timeit(stmt = "fun5(l, 5)", number = 1000, globals = globals()))
    print("")
    print("Method 6, numpy given np.ndarray:")
    print(timeit(stmt = "fun5(l2, 5)", number = 1000, globals = globals()))
    print("")

When run as main, this results in the following printout on my machine indicating time in seconds to complete 1000 trials of each function:

Method 1: 0.7502102799990098

Method 2: 0.7291318440002215

Method 3: 0.24142152300009911

Method 4: 0.5253471979995084

Method 5, numpy given list: 0.5045417560013448

Method 6, numpy given np.ndarray: 0.011147511999297421

Of course the question asks specifically about lists so the best solution is to use the try-except method, however the speed improvements (at least 20x here compared to try-except) offered by using the numpy data structures and operators instead of python data structures is significant and if building something on many arrays of data that is performance critical then the author should try to use numpy throughout to take advantage of the superfast C bindings. (CPython interpreter, other interpreter performances may vary)

Btw, the reason Method 5 is much slower than Method 6 is because numpy first has to convert the given list to it's own numpy array, so giving it a list doesn't break it it just doesn't fully utilise the speed possible.

HTML are markup languages, basically they are set of tags like <html>, <body>, which is used to present a website using css, and javascript as a whole. All these, happen in the clients system or the user you will be browsing the website.

Now, Connecting to a database, happens on whole another level. It happens on server, which is where the website is hosted.

So, in order to connect to the database and perform various data related actions, you have to use server-side scripts, like php, jsp, asp.net etc.

Now, lets see a snippet of connection using MYSQLi Extension of PHP

$db = mysqli_connect('hostname','username','password','databasename');

This single line code, is enough to get you started, you can mix such code, combined with HTML tags to create a HTML page, which is show data based pages. For example:

<?php
    $db = mysqli_connect('hostname','username','password','databasename');
?>
<html>
    <body>
          <?php
                $query = "SELECT * FROM `mytable`;";
                $result = mysqli_query($db, $query);
                while($row = mysqli_fetch_assoc($result)) {
                      // Display your datas on the page
                }
          ?>
    </body>
</html>

In order to insert new data into the database, you can use phpMyAdmin or write a INSERT query and execute them.

Open the storyboard in the XML view and try to edit the rowHeight attribute of the wanted element.

It worked for me when I tried to set custom rowHeight for my prototyped row. It's not working via inspector, but via XML it works.

A workaround is to use a willAnswer() method.

For example the following works (and doesn't throw a MockitoException but actually throws a checked Exception as required here) using BDDMockito:

given(someObj.someMethod(stringArg1)).willAnswer( invocation -> { throw new Exception("abc msg"); });

The equivalent for plain Mockito would to use the doAnswer method

I am in the same situation pointed out by malcook in his comment: unfortunately the answer by Thierry does not work with ggplot2 version 0.9.3.1.

png("figure_%d.png")
set.seed(2014)
library(ggplot2)
dataset <- data.frame(category = rep(LETTERS[1:5], 100),
    x = rnorm(500, mean = rep(1:5, 100)),
    y = rnorm(500, mean = rep(1:5, 100)))
dataset$fCategory <- factor(dataset$category)
subdata <- subset(dataset, category %in% c("A", "D", "E"))

ggplot(dataset, aes(x = x, y = y, colour = fCategory)) + geom_point()
ggplot(subdata, aes(x = x, y = y, colour = fCategory)) + geom_point()

Here it is the first figure:

and the second figure:

As we can see the colors do not stay fixed, for example E switches from magenta to blu.

As suggested by malcook in his comment and by hadley in his comment the code which uses limits works properly:

ggplot(subdata, aes(x = x, y = y, colour = fCategory)) +       
    geom_point() + 
    scale_colour_discrete(drop=TRUE,
        limits = levels(dataset$fCategory))

gives the following figure, which is correct:

Check recursion from command line:

php -r 'function foo() { static $x = 1; echo "foo ", $x++, "\n"; foo(); } foo();'

if result > 100 THEN check memory limit;

When we want to copy an array using the assignment operator ( = ) it doesn't create a copy it merely copies the pointer/reference to the array. For example:

const oldArr = [1,2,3];_x000D_
_x000D_
const newArr = oldArr;  // now oldArr points to the same place in memory _x000D_
_x000D_
console.log(oldArr === newArr);  // Points to the same place in memory thus is true_x000D_
_x000D_
const copy = [1,2,3];_x000D_
_x000D_
console.log(copy === newArr);  // Doesn't point to the same place in memory and thus is false

Often when we transform data we want to keep our initial datastructure (e.g. Array) intact. We do this by making a exact copy of our array so this one can be transformed while the initial one stays intact.

Ways of copying an array:

const oldArr = [1,2,3];_x000D_
_x000D_
// Uses the spread operator to spread out old values into the new array literal_x000D_
const newArr1 = [...oldArr];_x000D_
_x000D_
// Slice with no arguments returns the newly copied Array_x000D_
const newArr2 = oldArr.slice();_x000D_
_x000D_
// Map applies the callback to every element in the array and returns a new array_x000D_
const newArr3 = oldArr.map((el) => el);_x000D_
_x000D_
// Concat is used to merge arrays and returns a new array. Concat with no args copies an array_x000D_
const newArr4 = oldArr.concat();_x000D_
_x000D_
// Object.assign can be used to transfer all the properties into a new array literal_x000D_
const newArr5 = Object.assign([], oldArr);_x000D_
_x000D_
// Creating via the Array constructor using the new keyword_x000D_
const newArr6 = new Array(...oldArr);_x000D_
_x000D_
// For loop_x000D_
function clone(base) {_x000D_
 const newArray = [];_x000D_
    for(let i= 0; i < base.length; i++) {_x000D_
     newArray[i] = base[i];_x000D_
 }_x000D_
 return newArray;_x000D_
}_x000D_
_x000D_
const newArr7 = clone(oldArr);_x000D_
_x000D_
console.log(newArr1, newArr2, newArr3, newArr4, newArr5, newArr6, newArr7);

Be careful when arrays or objects are nested!:

When arrays are nested the values are copied by reference. Here is an example of how this could lead to issues:

let arr1 = [1,2,[1,2,3]]_x000D_
_x000D_
let arr2 = [...arr1];_x000D_
_x000D_
arr2[2][0] = 5;  // we change arr2_x000D_
_x000D_
console.log(arr1);  // arr1 is also changed because the array inside arr1 was copied by reference

So don't use these methods when there are objects or arrays inside your array you want to copy. i.e. Use these methods on arrays of primitives only.

If you do want to deepclone a javascript array use JSON.parse in conjunction with JSON.stringify, like this:

let arr1 = [1,2,[1,2,3]]_x000D_
_x000D_
let arr2 = JSON.parse(JSON.stringify(arr1)) ;_x000D_
_x000D_
arr2[2][0] = 5;_x000D_
_x000D_
console.log(arr1);  // now I'm not modified because I'm a deep clone

Performance of copying:

So which one do we choose for optimal performance. It turns out that the most verbose method, the for loop has the highest performance. Use the for loop for really CPU intensive copying (large/many arrays).

After that the .slice() method also has decent performance and is also less verbose and easier for the programmer to implement. I suggest to use .slice() for your everyday copying of arrays which aren't very CPU intensive. Also avoid using the JSON.parse(JSON.stringify(arr)) (lots of overhead) if no deep clone is required and performance is an issue.

Source performance test

There are 4 dimensions of the tensor you want to convert.

[:, ::-1, :, :] 

: means that the first dimension should be copied as it is and converted, same goes for the third and fourth dimension.

::-1 means that for the second axes it reverses the the axes

OK. We have official document now. It talked all I have mentioned, in a better way.

Read more detailed here.

Yes, the main difference is surfaceView can be updated on the background thread. However, there are more you might care.

• surfaceView has dedicate surface buffer while all the view shares one surface buffer that is allocated by ViewRoot. In another word, surfaceView cost more resources.

• surfaceView cannot be hardware accelerated (as of JB4.2) while 95% operations on normal View are HW accelerated using openGL ES.

• More work should be done to create your customized surfaceView. You need to listener to the surfaceCreated/Destroy Event, create an render thread, more importantly, synchronized the render thread and main thread. However, to customize the View, all you need to do is override onDraw method.

• The timing to update is different. Normal view update mechanism is constraint or controlled by the framework:You call view.invalidate in the UI thread or view.postInvalid in other thread to indicate to the framework that the view should be updated. However, the view won't be updated immediately but wait until next VSYNC event arrived. The easy approach to understand VSYNC is to consider it is as a timer that fire up every 16ms for a 60fps screen. In Android, all the normal view update (and display actually but I won't talk it today), is synchronized with VSYNC to achieve better smoothness. Now,back to the surfaceView, you can render it anytime as you wish. However, I can hardly tell if it is an advantage, since the display is also synchronized with VSYNC, as stated previously.

I had this same issue and I solved it as well by creating a custom renderer for iOS as Falko suggests, however, I avoided the styles modification for Android, I figured out a way to use a custom renderer for Android as well.

It is kind of funky how the selected flag is always false for the android view cell that's why I had to create a new private property to track it. but other than that I think this follows a more appropriate pattern if you want to use custom renderers for both platforms, In my case I did it for TextCell but I believe it applies the same way for other CellViews.

Xamarin Forms

using Xamarin.Forms;

public class CustomTextCell : TextCell
    {
        /// <summary>
        /// The SelectedBackgroundColor property.
        /// </summary>
        public static readonly BindableProperty SelectedBackgroundColorProperty =
            BindableProperty.Create("SelectedBackgroundColor", typeof(Color), typeof(CustomTextCell), Color.Default);

        /// <summary>
        /// Gets or sets the SelectedBackgroundColor.
        /// </summary>
        public Color SelectedBackgroundColor
        {
            get { return (Color)GetValue(SelectedBackgroundColorProperty); }
            set { SetValue(SelectedBackgroundColorProperty, value); }
        }
    }

iOS

public class CustomTextCellRenderer : TextCellRenderer
    {
        public override UITableViewCell GetCell(Cell item, UITableViewCell reusableCell, UITableView tv)
        {
            var cell = base.GetCell(item, reusableCell, tv);
            var view = item as CustomTextCell;
            cell.SelectedBackgroundView = new UIView
            {
                BackgroundColor = view.SelectedBackgroundColor.ToUIColor(),
            };

            return cell;
        }
    }

Android

public class CustomTextCellRenderer : TextCellRenderer
{
    private Android.Views.View cellCore;
    private Drawable unselectedBackground;
    private bool selected;

    protected override Android.Views.View GetCellCore(Cell item, Android.Views.View convertView, ViewGroup parent, Context context)
    {
        cellCore = base.GetCellCore(item, convertView, parent, context);

        // Save original background to rollback to it when not selected,
        // We assume that no cells will be selected on creation.
        selected = false;
        unselectedBackground = cellCore.Background;

        return cellCore;
    }

    protected override void OnCellPropertyChanged(object sender, PropertyChangedEventArgs args)
    {
        base.OnCellPropertyChanged(sender, args);

        if (args.PropertyName == "IsSelected")
        {
            // I had to create a property to track the selection because cellCore.Selected is always false.
            // Toggle selection
            selected = !selected;

            if (selected)
            {
                var customTextCell = sender as CustomTextCell;
                cellCore.SetBackgroundColor(customTextCell.SelectedBackgroundColor.ToAndroid());
            }
            else
            {
                cellCore.SetBackground(unselectedBackground);
            }
        }
    }
}

...then, in the .xaml page, you need to add an XMLNS reference back to the new CustomViewCell...

xmlns:customuicontrols="clr-namespace:MyMobileApp.CustomUIControls"

And don't forget to make actual use of the new Custom comtrol in your XAML.

For Node/Express developers you can use middleware and set this via server.

app.use(function(req, res, next) {
  res.setHeader('X-UA-Compatible', 'IE=edge');
  next();
});

The short answer is: don't. (...) You really can't. And that's a good thing

I'd like to set the record straight regarding this:

NodeJS does support Synchronous Requests. It wasn't designed to support them out of the box, but there are a few workarounds if you are keen enough, here is an example:

var request = require('sync-request'),
    res1, res2, ucomp, vcomp;

try {
    res1 = request('GET', base + u_ext);
    res2 = request('GET', base + v_ext);
    ucomp = res1.split('\n')[1].split(', ')[1];
    vcomp = res2.split('\n')[1].split(', ')[1];
    doSomething(ucomp, vcomp);

} catch (e) {}

When you pop the hood open on the 'sync-request' library you can see that this runs a synchronous child process in the background. And as is explained in the sync-request README it should be used very judiciously. This approach locks the main thread, and that is bad for performance.

However, in some cases there is little or no advantage to be gained by writing an asynchronous solution (compared to the certain harm you are doing by writing code that is harder to read).

This is the default assumption held by many of the HTTP request libraries in other languages (Python, Java, C# etc), and that philosophy can also be carried to JavaScript. A language is a tool for solving problems after all, and sometimes you may not want to use callbacks if the benefits outweigh the disadvantages.

For JavaScript purists this may rankle of heresy, but I'm a pragmatist so I can clearly see that the simplicity of using synchronous requests helps if you find yourself in some of the following scenarios:

1. Test Automation (tests are usually synchronous by nature).

2. Quick API mash-ups (ie hackathon, proof of concept works etc).

3. Simple examples to help beginners (before and after).

Be warned that the code above should not be used for production. If you are going to run a proper API then use callbacks, use promises, use async/await, or whatever, but avoid synchronous code unless you want to incur a significant cost for wasted CPU time on your server.

If you are matching the full value of the field use

WHERE UPPER(fieldName) = 'ANGEL'

EDIT: From your comment you want to use:

SELECT 
    RPAD(a.name, 10,'=') "Nombre del Cliente"
    , RPAD(b.name, 12,'*') "Nombre del Consumidor" 
FROM 
    s_customer a, 
    s_region b 
WHERE 
    a.region_id = b.id 
    AND UPPER(a.name) LIKE '%SPORT%' 

I just deleted my ~/.m2/repository and that forced a re-download ;)

None of the above worked for me. This is what finally worked for me:

1) Start Services (Type services in your start > search)
2) Look for Apache services.It was disabled in my case. Enabling it worked for me.

Some people have also reported duplicate listing of Apache services which has prevented it from starting. If that is the case, delete/disable one of the Apache services which corresponds to the wrong path.

A restart of XAMPP might be required.

you can add this style to your buttons:

To add to Rob's answer, since iOS 10.0, Apple has introduced an entirely new "Unified Logging" system that supersedes existing logging systems (including ASL and Syslog, NSLog), and also surpasses existing logging approaches in performance, thanks to its new techniques including log data compression and deferred data collection.

From Apple:

The unified logging system provides a single, efficient, performant API for capturing messaging across all levels of the system. This unified system centralizes the storage of log data in memory and in a data store on disk.

Apple highly recommends using os_log going forward to log all kinds of messages, including info, debug, error messages because of its much improved performance compared to previous logging systems, and its centralized data collection allowing convenient log and activity inspection for developers. In fact, the new system is likely so low-footprint that it won't cause the "observer effect" where your bug disappears if you insert a logging command, interfering the timing of the bug to happen.

You can learn more about this in details here.

To sum it up: use print() for your personal debugging for convenience (but the message won't be logged when deployed on user devices). Then, use Unified Logging (os_log) as much as possible for everything else.

First navigate to below location and open it in a text editor

<TOMCAT_HOME>/conf/tomcat-users.xml

For tomcat 7, Add the following xml code somewhere between <tomcat-users> I find the following solution.

  <role rolename="manager-gui"/>
  <user username="username" password="password" roles="manager-gui"/>

Now restart the tomcat server.

Weirdness is highly subjective, I just suggest to follow the official recommendation:

Guide to naming conventions on groupId, artifactId and version

• groupId will identify your project uniquely across all projects, so we need to enforce a naming schema. It has to follow the package name rules, what means that has to be at least as a domain name you control, and you can create as many subgroups as you want. Look at More information about package names.

  eg. org.apache.maven, org.apache.commons

  A good way to determine the granularity of the groupId is to use the project structure. That is, if the current project is a multiple module project, it should append a new identifier to the parent's groupId.

  eg. org.apache.maven, org.apache.maven.plugins, org.apache.maven.reporting

• artifactId is the name of the jar without version. If you created it then you can choose whatever name you want with lowercase letters and no strange symbols. If it's a third party jar you have to take the name of the jar as it's distributed.

  eg. maven, commons-math

• version if you distribute it then you can choose any typical version with numbers and dots (1.0, 1.1, 1.0.1, ...). Don't use dates as they are usually associated with SNAPSHOT (nightly) builds. If it's a third party artifact, you have to use their version number whatever it is, and as strange as it can look.

  eg. 2.0, 2.0.1, 1.3.1

New-style classes inherit from object, or from another new style class:

class SomeObject(object):
    pass

class SubObject(SomeObject):
    pass

Old-style classes don't:

class SomeObject:
    pass

This only applies to Python 2 - in Python 3 all the above will create new-style classes.

See 9. Classes (Python tutorial), NewClassVsClassicClass and What is the difference between old style and new style classes in Python? for details.

I had the same issue with setting StatusCode and then Response.End in HandleUnauthorizedRequest method of AuthorizeAttribute

var ctx = filterContext.HttpContext;
ctx.Response.StatusCode = (int)HttpStatusCode.Forbidden;
ctx.Response.End();

If you are using .NET 4.5+, add this line before Response.StatusCode

filterContext.HttpContext.Response.SuppressFormsAuthenticationRedirect = true;

If you are using .NET 4.0, try SuppressFormsAuthenticationRedirectModule.

Complementing @Bob Jarvis and @dmikam answer, Postgres don't perform a good plan when you don't use LATERAL, below a simulation, in both cases the query data results are the same, but the cost are very different

Table structure

CREATE TABLE ITEMS (
    N INTEGER NOT NULL,
    S TEXT NOT NULL
);

INSERT INTO ITEMS
  SELECT
    (random()*1000000)::integer AS n,
    md5(random()::text) AS s
  FROM
    generate_series(1,1000000);

CREATE INDEX N_INDEX ON ITEMS(N);

Performing JOIN with GROUP BY in subquery without LATERAL

EXPLAIN 
SELECT 
    I.*
FROM ITEMS I
INNER JOIN (
    SELECT 
        COUNT(1), n
    FROM ITEMS
    GROUP BY N
) I2 ON I2.N = I.N
WHERE I.N IN (243477, 997947);

The results

Merge Join  (cost=0.87..637500.40 rows=23 width=37)
  Merge Cond: (i.n = items.n)
  ->  Index Scan using n_index on items i  (cost=0.43..101.28 rows=23 width=37)
        Index Cond: (n = ANY ('{243477,997947}'::integer[]))
  ->  GroupAggregate  (cost=0.43..626631.11 rows=861418 width=12)
        Group Key: items.n
        ->  Index Only Scan using n_index on items  (cost=0.43..593016.93 rows=10000000 width=4)

Using LATERAL

EXPLAIN 
SELECT 
    I.*
FROM ITEMS I
INNER JOIN LATERAL (
    SELECT 
        COUNT(1), n
    FROM ITEMS
    WHERE N = I.N
    GROUP BY N
) I2 ON 1=1 --I2.N = I.N
WHERE I.N IN (243477, 997947);

Results

Nested Loop  (cost=9.49..1319.97 rows=276 width=37)
  ->  Bitmap Heap Scan on items i  (cost=9.06..100.20 rows=23 width=37)
        Recheck Cond: (n = ANY ('{243477,997947}'::integer[]))

              Index Cond: (n = i.n)

My Postgres version is PostgreSQL 10.3 (Debian 10.3-1.pgdg90+1)

Just create .htaccess file at root and add these lines to it

<IfModule mod_rewrite.c>
    RewriteEngine On

    RewriteRule ^(.*)$ public/$1 [L]
</IfModule>

That's it!

The above code works on the root public_html folder. Having said that your core laravel file should be inside the public_html folder, if your directory looks like public_html/laravelapp/public and if you put the above code inside laravelapp it won't work. Therefore you must copy all your core files into public_html and put the .htaccess file there .

If you want to keep the code in a subdirectory then you can create a subdomain then this code will work for that also.

This is very similar to another stackoverflow article, Bind a function to Twitter Bootstrap Modal Close. Assuming you are using some version of Bootstap v3 or v4, you can do something like the following:

$("#myModal").on("hidden.bs.modal", function () {
    // put your default event here
});

jQuery("select#cboDays option[value='Wednesday']").attr("selected", "selected");

You may try this

#headerAgentInfoDetailsPhone
{
    white-space:pre
}
#headerAgentInfoDetailsPhone:after {
    content:"Office: XXXXX \A Mobile: YYYYY ";
}

Try setting a height on your td elements.

vertical-align: middle; 

means the element the style is applied to will be aligned within the parent element. The height of the td may be only as high as the text inside.

It should work with:

.modal:before{
   opacity:0.001 !important;
}

Code Runner Extension will only let you "run" java files.

To truly debug 'Java' files follow the quick one-time setup:

• Install Java Debugger Extension in VS Code and reload.
• open an empty folder/project in VS code.
• create your java file (s).
• create a folder .vscode in the same folder.
• create 2 files inside .vscode folder: tasks.json and launch.json
• copy paste below config in tasks.json:

{
    "version": "2.0.0",
    "type": "shell",
    "presentation": {
        "echo": true,
        "reveal": "always",
        "focus": false,
        "panel": "shared"
    },
    "isBackground": true,
    "tasks": [
        {
            "taskName": "build",
            "args": ["-g", "${file}"],
            "command": "javac"
        }
    ]
}

• copy paste below config in launch.json:

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Debug Java",
            "type": "java",
            "request": "launch",
            "externalConsole": true,                //user input dosen't work if set it to false :(
            "stopOnEntry": true,
            "preLaunchTask": "build",                 // Runs the task created above before running this configuration
            "jdkPath": "${env:JAVA_HOME}/bin",        // You need to set JAVA_HOME enviroment variable
            "cwd": "${workspaceRoot}",
            "startupClass": "${workspaceRoot}${file}",
            "sourcePath": ["${workspaceRoot}"],   // Indicates where your source (.java) files are
            "classpath": ["${workspaceRoot}"],    // Indicates the location of your .class files
            "options": [],                             // Additional options to pass to the java executable
            "args": []                                // Command line arguments to pass to the startup class
        }

    ],
    "compounds": []
}

You are all set to debug java files, open any java file and press F5 (Debug->Start Debugging).

Tip: *To hide .class files in the side explorer of VS code, open settings of VS code and paste the below config:

"files.exclude": {
        "*.class": true
    }

Your database, that apparently has the ORACLE_SID XE, is not defined in the listener.ora. That is no problem, since when the database normally opens, it will register itself to the default listener, being the one on port 1521 so that is ok.

1. is the database open?
2. what is the start order of listener/database?
3. is the error persistent?

If the database starts before the listener, the database has no listener to register to. It will do so every few minutes so after a while, I expect the error will go away because of the registration has taken place. You can issue alter system register; to speed this. If the database is in restricted mode, the connections using a service will fail. You are using ORACLE_SID so that is not your problem.

Also check the names in use. Is localhost resolving to the same address as Brodyaga-PC? In the jdbc string you use localhost and the listener listens om Brodyaga-PC. Is localhost 127.0.0.1 ?

You don't need regex to split a string on whitespace:

In [2]: print '\n'.join(line.split()[0] for line in text.split('\n'))

If double-clicking on it brings up WinRAR, you need to change the program you are running it with. You can right-click on it and click "Open with". Java should be listed in there.

However, you must first upgrade your Java version to be compatible with that JAR.

Assuming you are writing a bootloader or other application that has access to the BIOS, here is a rough sketch of what you can do:

• Isolate the first digit of the hex byte
• If it is greater than 9 (i.e. 0x0A to 0x0F), subtract 10 from it (scaling it down to 0 to 5), and add 'A' (0x41).
• If it is less than or equal to 9 (i.e. 0x00 to 0x09), add '0' to it.
• Repeat this with the next hex digit.

Here is my implementation of this:

; Prints AL in hex.
printhexb:
    push ax
    shr al, 0x04
    call print_nibble
    pop ax
    and al, 0x0F
    call print_nibble
    ret
print_nibble:
    cmp al, 0x09
    jg .letter
    add al, 0x30
    mov ah, 0x0E
    int 0x10
    ret
.letter:
    add al, 0x37
    mov ah, 0x0E
    int 0x10
    ret   

If you're using the Vixie Cron, e.g. on most Linux distributions, you can just put a file in /etc/cron.d with the individual cronjob.

This only works for root of course. If your system supports this you should see several examples in there. (Note the username included in the line, in the same syntax as the old /etc/crontab)

It's a sad misfeature in cron that there is no way to handle this as a regular user, and that so many cron implementations have no way at all to handle this.

If you are issuing a single command with several select statements, you might use NextResult method to move to next resultset within the datareader: http://msdn.microsoft.com/en-us/library/system.data.idatareader.nextresult.aspx

I show how it could look bellow:

public DataSet SelectOne(int id)
{
    DataSet result = new DataSet();
    using (DbCommand command = Connection.CreateCommand())
    {
        command.CommandText = @"
select * from table1
select * from table2
        ";

        var param = ParametersBuilder.CreateByKey(command, "ID", id, null);
        command.Parameters.Add(param);

        Connection.Open();
        using (DbDataReader reader = command.ExecuteReader())
        {
            result.MainTable.Load(reader);
            reader.NextResult();
            result.SecondTable.Load(reader);
            // ...
        }
        Connection.Close();
    }
    return result;
}

Jump if the status is "Not set" on Equal/Zero flag

"Not set" is a status when "equal/zero flag" in the CPU is set to 0 which only happens when the condition is met or equally matched.

One way to solve this error is to put the ForeignKey attribute on top of the property you want as a foreign key and add the navigation property.

Note: In the ForeignKey attribute, between parentheses and double quotes, place the name of the class referred to in this way.

Read Cookie in Web Api

var cookie = actionContext.Request.Headers.GetCookies("newhbsslv1");


                    Logger.Log("Cookie  " + cookie, LoggerLevel.Info);
                    Logger.Log("Cookie count  " + cookie.Count, LoggerLevel.Info);

                    if (cookie != null && cookie.Count > 0)

                        }
                    }

You can use .toFixed(0) to remove complete decimal part or provide the number in arguments upto which you want decimal to be truncated.

Note: toFixed will convert the number to string.

From the Spring reference, 3.2.3.1 Naming Beans:

Every bean has one or more ids (also called identifiers, or names; these terms refer to the same thing). These ids must be unique within the container the bean is hosted in. A bean will almost always have only one id, but if a bean has more than one id, the extra ones can essentially be considered aliases.

When using XML-based configuration metadata, you use the 'id' or 'name' attributes to specify the bean identifier(s). The 'id' attribute allows you to specify exactly one id, and as it is a real XML element ID attribute, the XML parser is able to do some extra validation when other elements reference the id; as such, it is the preferred way to specify a bean id. However, the XML specification does limit the characters which are legal in XML IDs. This is usually not a constraint, but if you have a need to use one of these special XML characters, or want to introduce other aliases to the bean, you may also or instead specify one or more bean ids, separated by a comma (,), semicolon (;), or whitespace in the 'name' attribute.

So basically the id attribute conforms to the XML id attribute standards whereas name is a little more flexible. Generally speaking, I use name pretty much exclusively. It just seems more "Spring-y".

You want the NPGSQL library. Your only other alternative is ODBC.

Some of Methods mentioned above ignores if there are any integers and float with values 0 & 0.0

If someone wants to avoid the above can use below code(removes empty strings and None values from nested dictionary and nested list):

def remove_empty_from_dict(d):
    if type(d) is dict:
        _temp = {}
        for k,v in d.items():
            if v == None or v == "":
                pass
            elif type(v) is int or type(v) is float:
                _temp[k] = remove_empty_from_dict(v)
            elif (v or remove_empty_from_dict(v)):
                _temp[k] = remove_empty_from_dict(v)
        return _temp
    elif type(d) is list:
        return [remove_empty_from_dict(v) for v in d if( (str(v).strip() or str(remove_empty_from_dict(v)).strip()) and (v != None or remove_empty_from_dict(v) != None))]
    else:
        return d

Here's an ECMA-style implementation:

function gcd(a, b){
    // Euclidean algorithm
    while (b != 0){
        var temp = b;
        b = a % b;
        a = temp;
    }
    return a;
}

function lcm(a, b){
    return (a * b / gcd(a, b));
}

function lcmm(args){
    // Recursively iterate through pairs of arguments
    // i.e. lcm(args[0], lcm(args[1], lcm(args[2], args[3])))

    if(args.length == 2){

use this one line script: ifconfig | grep "inet " | grep -v 127.0.0.1|awk 'match($0, /([0-9]+\.[0-9]+\.[0-9]+\.[0-9]+)/) {print substr($0,RSTART,RLENGTH)}' mac & linux (tested in ubuntu) both works.

Since Spark 1.5 you can use a number of date processing functions:

• pyspark.sql.functions.year
• pyspark.sql.functions.month
• pyspark.sql.functions.dayofmonth
• pyspark.sql.functions.dayofweek()
• pyspark.sql.functions.dayofyear
• pyspark.sql.functions.weekofyear()

import datetime
from pyspark.sql.functions import year, month, dayofmonth

elevDF = sc.parallelize([
    (datetime.datetime(1984, 1, 1, 0, 0), 1, 638.55),
    (datetime.datetime(1984, 1, 1, 0, 0), 2, 638.55),
    (datetime.datetime(1984, 1, 1, 0, 0), 3, 638.55),
    (datetime.datetime(1984, 1, 1, 0, 0), 4, 638.55),
    (datetime.datetime(1984, 1, 1, 0, 0), 5, 638.55)
]).toDF(["date", "hour", "value"])

elevDF.select(
    year("date").alias('year'), 
    month("date").alias('month'), 
    dayofmonth("date").alias('day')
).show()
# +----+-----+---+
# |year|month|day|
# +----+-----+---+
# |1984|    1|  1|
# |1984|    1|  1|
# |1984|    1|  1|
# |1984|    1|  1|
# |1984|    1|  1|
# +----+-----+---+

You can use simple map as with any other RDD:

elevDF = sqlContext.createDataFrame(sc.parallelize([
        Row(date=datetime.datetime(1984, 1, 1, 0, 0), hour=1, value=638.55),
        Row(date=datetime.datetime(1984, 1, 1, 0, 0), hour=2, value=638.55),
        Row(date=datetime.datetime(1984, 1, 1, 0, 0), hour=3, value=638.55),
        Row(date=datetime.datetime(1984, 1, 1, 0, 0), hour=4, value=638.55),
        Row(date=datetime.datetime(1984, 1, 1, 0, 0), hour=5, value=638.55)]))

(elevDF
 .map(lambda (date, hour, value): (date.year, date.month, date.day))
 .collect())

and the result is:

[(1984, 1, 1), (1984, 1, 1), (1984, 1, 1), (1984, 1, 1), (1984, 1, 1)]

Btw: datetime.datetime stores an hour anyway so keeping it separately seems to be a waste of memory.

Using url-loader, described here (SurviveJS - Loading Images), you can then use in your code :

import LogoImg from 'YOUR_PATH/logo.png';

and

<img src={LogoImg}/>

Edit: a precision, images are inlined in the js archive with this technique. It can be worthy for small images, but use the technique wisely.

$_='~s/blue/red/g';

Uh, what??

Just

s/blue/red/g;

or, if you insist on using a variable (which is not necessary when using $_, but I just want to show the right syntax):

$_ =~ s/blue/red/g;

Client send some messages need be compressed, server (kafka) decompress the string meesage

Below is my sample:

compress:

   public static String compress(String str, String inEncoding) {
        if (str == null || str.length() == 0) {
            return str;
        }
        try {
            ByteArrayOutputStream out = new ByteArrayOutputStream();
            GZIPOutputStream gzip = new GZIPOutputStream(out);
            gzip.write(str.getBytes(inEncoding));
            gzip.close();
            return URLEncoder.encode(out.toString("ISO-8859-1"), "UTF-8");
        } catch (IOException e) {
            e.printStackTrace();
        }
        return null;
    }

decompress:

    public static String decompress(String str, String outEncoding) {
        if (str == null || str.length() == 0) {
            return str;
        }

        try {
            String decode = URLDecoder.decode(str, "UTF-8");

            ByteArrayOutputStream out = new ByteArrayOutputStream();
            ByteArrayInputStream in = new ByteArrayInputStream(decode.getBytes("ISO-8859-1"));
            GZIPInputStream gunzip = new GZIPInputStream(in);
            byte[] buffer = new byte[256];
            int n;
            while ((n = gunzip.read(buffer)) >= 0) {
                out.write(buffer, 0, n);
            }
            return out.toString(outEncoding);
        } catch (IOException e) {
            e.printStackTrace();
        }
        return null;
    }

I didn't want to mess with additional libraries. Simple ways suggested here didn't work out either. Finally, not on the request object, but I could get a GET parameter w/o all that hassle via self.GET.get('XXX'):

...
def get_context_data(self, **kwargs):
    context = super(SomeView, self).get_context_data(**kwargs)
    context['XXX'] = self.GET.get('XXX')

I'm a big fan of Autohotkey. I defined a 'paste plain text' macro that works in any application. It runs when I press Ctrl+Shift+V and pastes a plain version of whatever is on the clipboard. The nice thing about Autohotkey: you can code things to work the way you want them to work across all applications.

^+v::
    ; Convert any copied files, HTML, or other formatted text to plain text
    Clipboard = %Clipboard%

    ; Paste by pressing Ctrl+V
    SendInput, ^v
return

If you want to keep the database between uninstalls you have to put it on the SD Card. This is the only place that won't be deleted at the moment your app is deleted. But in return it can be deleted by the user every time.

If you put your DB on the SD Card you can't use the SQLiteOpenHelper anymore, but you can use the source and the architecture of this class to get some ideas on how to implement the creation, updating and opening of a databse.

extension UITapGestureRecognizer {

    func didTapAttributedTextInLabel(label: UILabel, inRange targetRange: NSRange) -> Bool {

        let layoutManager = NSLayoutManager()
        let textContainer = NSTextContainer(size: CGSize.zero)
        let textStorage = NSTextStorage(attributedString: label.attributedText!)

        // Configure layoutManager and textStorage
        layoutManager.addTextContainer(textContainer)
        textStorage.addLayoutManager(layoutManager)

        // Configure textContainer
        textContainer.lineFragmentPadding = 0.0
        textContainer.lineBreakMode = label.lineBreakMode
        textContainer.maximumNumberOfLines = label.numberOfLines
        textContainer.size = label.bounds.size

        // main code
        let locationOfTouchInLabel = self.location(in: label)

        let indexOfCharacter = layoutManager.characterIndex(for: locationOfTouchInLabel, in: textContainer, fractionOfDistanceBetweenInsertionPoints: nil)
        let indexOfCharacterRange = NSRange(location: indexOfCharacter, length: 1)
        let indexOfCharacterRect = layoutManager.boundingRect(forGlyphRange: indexOfCharacterRange, in: textContainer)
        let deltaOffsetCharacter = indexOfCharacterRect.origin.x + indexOfCharacterRect.size.width

        if locationOfTouchInLabel.x > deltaOffsetCharacter {
            return false
        } else {
            return NSLocationInRange(indexOfCharacter, targetRange)
        }
    }
}

JTextField allows us to getText() and setText() these are used to get and set the contents of the text field, for example.

text = texfield.getText();

hope this helps

For just quickly viewing the cookies on any particular page, I keep a favorites-bar "Cookies" shortcut with the URL set to:

javascript:window.alert(document.cookie.split(';').join(';\r\n'));

You can not alter constraints ever but you can drop them and then recreate.

Have look on this

ALTER TABLE your_table DROP CONSTRAINT ACTIVEPROG_FKEY1;

and then recreate it with ON DELETE CASCADE like this

ALTER TABLE your_table
add CONSTRAINT ACTIVEPROG_FKEY1 FOREIGN KEY(ActiveProgCode) REFERENCES PROGRAM(ActiveProgCode)
    ON DELETE CASCADE;

hope this help

Here is a function I just wrote in jQuery to do it - you can port it to Prototype, but they don't support the "liveness" of jQuery so elements added by Ajax requests will not respond.

This version not only expands, but it also contracts when delete or backspace is pressed.

This version relies on jQuery 1.4.2.

Enjoy ;)

http://pastebin.com/SUKeBtnx

Usage:

$("#sometextarea").textareacontrol();

or (any jQuery selector for example)

$("textarea").textareacontrol();

It was tested on Internet Explorer 7/Internet Explorer 8, Firefox 3.5, and Chrome. All works fine.

set @cnt=0;
select s.* from (SELECT  (@cnt := @cnt + 1) AS rank,a.* FROM one as a  order by a.salary DESC) as s WHERE s.rank='3';

=>this for 3rd highest salary. for nth replace 3 value. for example 5th highest:

set @cnt=0;
select s.* from (SELECT  (@cnt := @cnt + 1) AS rank,a.* FROM one as a  order by a.salary DESC) as s WHERE s.rank='5';

Ideally the pivot should be the middle value in the entire array. This will reduce the chances of getting worst case performance.

From documentation:

To comply with the SQL standard, IN returns NULL not only if the expression on the left hand side is NULL, but also if no match is found in the list and one of the expressions in the list is NULL.

This is exactly your case.

Both IN and NOT IN return NULL which is not an acceptable condition for WHERE clause.

Rewrite your query as follows:

SELECT  *
FROM    match m
WHERE   NOT EXISTS
        (
        SELECT  1
        FROM    email e
        WHERE   e.id = m.id
        )

use:

String[] mStrings = new String[title.length];

Another option would be to set a flag variable as a Boolean and then change that value based on your criteria.

Dim count as Integer 
Dim flag as Boolean

flag = True

While flag
    count = count + 1 

    If count = 10 Then
        'Set the flag to false         '
        flag = false
    End If 
Wend

The classical way to achieve this is to put the text into the div and use an image replacement technique.

<div class"ir background-image">Your alt text</div>

with background-image beeing the class where you assign the background image and ir could be HTML5boilerplates image replacement class, below:

/* ==========================================================================
   Helper classes
   ========================================================================== */

/*
 * Image replacement
 */

.ir {
    background-color: transparent;
    border: 0;
    overflow: hidden;
    /* IE 6/7 fallback */
    *text-indent: -9999px;
}

.ir:before {
    content: "";
    display: block;
    width: 0;
    height: 150%;
}

To guess what's the source encoding you can use the file *nix command.

Example:

$ file --mime jumper.xml

jumper.xml: application/xml; charset=utf-8

You are trying to insert a record with a value in the foreign key column that doesn't exist in the foreign table.

For example: If you have Books and Authors tables where Books has a foreign key constraint on the Authors table and you try to insert a book record for which there is no author record.

This will also work on iOS:

<input type="text" onclick="this.focus(); this.setSelectionRange(0, 9999);" />

An anonymous class is extending or implementing while creating its object For example :

Interface in = new InterFace()
{

..............

}

Here anonymous class is implementing Interface.

Class cl = new Class(){

.................

}

here anonymous Class is extending a abstract Class.

First, declare the output variable:

DECLARE @MyOutputParameter INT;

Then, execute the stored procedure, and you can do it without parameter's names, like this:

EXEC my_stored_procedure 'param1Value', @MyOutputParameter OUTPUT

or with parameter's names:

EXEC my_stored_procedure @param1 = 'param1Value', @myoutput = @MyOutputParameter OUTPUT

And finally, you can see the output result by doing a SELECT:

SELECT @MyOutputParameter 

$SQL_Part="("
$i=0;
while ($i<length($cat)-1)
{
   $SQL_Part+=$cat[i]+",";
}
$SQL_Part=$SQL_Part+$cat[$i+1]+")"

$SQL="SELECT * FROM products WHERE catid IN "+$SQL_Part;

It's more generic and will fit for any array!!

}

I know there are many other answers, but here is another way to do it using the sort and rle functions. The function rle stands for Run Length Encoding. It can be used for counts of runs of numbers (see the R man docs on rle), but can also be applied here.

test.data = rep(c(1, 2, 2, 2), 25)
rle(sort(test.data))
## Run Length Encoding
##   lengths: int [1:2] 25 75
##   values : num [1:2] 1 2

If you capture the result, you can access the lengths and values as follows:

## rle returns a list with two items.
result.counts <- rle(sort(test.data))
result.counts$lengths
## [1] 25 75
result.counts$values
## [1] 1 2

You're tired and cant do any more work. You eat food. The energy spent looking for food, getting it and actually eating it consumes energy and is overhead!

Overhead is something wasted in order to accomplish a task. The goal is to make overhead very very small.

In computer science lets say you want to print a number, thats your task. But storing the number, the setting up the display to print it and calling routines to print it, then accessing the number from variable are all overhead.

In your GIT view where you have your repositories you will see a structure such as:

• branches
• tags
• references
• remotes
• etc...

Click on remotes, right-click on the url of the repository there and select 'Change Credentials'.

Check your log4j.properties file

Check easy example here at here.

If your object could contain any key/value pairs, you could declare an interface called keyable like :

interface keyable {
    [key: string]: any  
}

then use it as follows :

let countryProviders: keyable[];

or

let countryProviders: Array<keyable>;

Today NodeJS supports new async/await syntax. This is an easy syntax and makes the life much easier

async function process(promises) { // must be an async function
    let x = await Promise.all(promises);  // now x will be an array
    x = x.map( tmp => tmp * 10);              // proccessing the data.
}

const promises = [
   new Promise(resolve => setTimeout(resolve, 0, 1)),
   new Promise(resolve => setTimeout(resolve, 0, 2))
];

process(promises)

Would this relationship not be better expressed as a one-to-many foreign key relationship to a Friends table? I understand that myFriends are just strings but I would think that a better design would be to create a Friend model and have MyClass contain a foreign key realtionship to the resulting table.

also one of the popular reasons maybe you miss to include the service file in your page

You could do something like:

find . -type d > dirs.txt

to create the list of directories, then

xargs mkdir -p < dirs.txt

to create the directories on the destination.

I use this for most situations, keep the seed if there is a need to repeat the sequence

After upgrading the Application. I observed different Cordova versions.

1. Apache Cordova Cli version which is 6.0.0.
2. Cordova Android version which is 5.1.0.
3. Cordova IOS version which is 4.1.1.
4. Docs version is which is 6.0.0, shown on the Cordova Docs website.

Now i am confused, On which version basis, Google Dev Console is giving warning?

Please migrate your app(s) to Apache Cordova v.4.1.1 or higher as soon as possible and increment the version number of the upgraded APK. Beginning May 9, 2016, Google Play will block publishing of any new apps or updates that use pre-4.1.1 versions of Apache Cordova.

The vulnerabilities were addressed in Apache Cordova 4.1.1. If you’re using a 3rd party library that bundles Apache Cordova, you’ll need to upgrade it to a version that bundles Apache Cordova 4.1.1 or later.

And before upgrading. Our Application versions were these.

1. Apache Cordova Cli version which is 5.4.1.
2. Cordova Android version which is 4.1.1.
3. Cordova IOS version which is 3.9.1.
4. Docs version is which is 5.4.1, shown on the Cordova Docs website.

Since 10gR2, Oracle allows to fine-tune the behaviour of string comparisons by setting the NLS_COMP and NLS_SORT session parameters:

SQL> SET HEADING OFF
SQL> SELECT *
  2  FROM NLS_SESSION_PARAMETERS
  3  WHERE PARAMETER IN ('NLS_COMP', 'NLS_SORT');

NLS_SORT
BINARY

NLS_COMP
BINARY


SQL>
SQL> SELECT CASE WHEN 'abc'='ABC' THEN 1 ELSE 0 END AS GOT_MATCH
  2  FROM DUAL;

         0

SQL>
SQL> ALTER SESSION SET NLS_COMP=LINGUISTIC;

Session altered.

SQL> ALTER SESSION SET NLS_SORT=BINARY_CI;

Session altered.

SQL>
SQL> SELECT *
  2  FROM NLS_SESSION_PARAMETERS
  3  WHERE PARAMETER IN ('NLS_COMP', 'NLS_SORT');

NLS_SORT
BINARY_CI

NLS_COMP
LINGUISTIC


SQL>
SQL> SELECT CASE WHEN 'abc'='ABC' THEN 1 ELSE 0 END AS GOT_MATCH
  2  FROM DUAL;

         1

You can also create case insensitive indexes:

create index
   nlsci1_gen_person
on
   MY_PERSON
   (NLSSORT
      (PERSON_LAST_NAME, 'NLS_SORT=BINARY_CI')
   )
;

This information was taken from Oracle case insensitive searches. The article mentions REGEXP_LIKE but it seems to work with good old = as well.

In versions older than 10gR2 it can't really be done and the usual approach, if you don't need accent-insensitive search, is to just UPPER() both the column and the search expression.

To add to the above, the most obvious place to add stylesheet_link_tag is in your global application layout - application.html.erb.

The jQuery way:

$('#test').attr('id')

In your example:

$(document).ready(function() {_x000D_
  console.log($('#test').attr('id'));_x000D_
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>_x000D_
<div id="test"></div>

Or through the DOM:

$('#test').get(0).id;

or even :

$('#test')[0].id;

and reason behind usage of $('#test').get(0) in JQuery or even $('#test')[0] is that $('#test') is a JQuery selector and returns an array() of results not a single element by its default functionality

an alternative for DOM selector in jquery is

$('#test').prop('id')

which is different from .attr() and $('#test').prop('foo') grabs the specified DOM foo property, while $('#test').attr('foo') grabs the specified HTML foo attribute and you can find more details about differences here.

try this

In your model

If u want get all album data use

  function get_all_album_data() {

    $this->db->select ( '*' ); 
    $this->db->from ( 'Album' );
    $this->db->join ( 'Category', 'Category.cat_id = Album.cat_id' , 'left' );
    $this->db->join ( 'Soundtrack', 'Soundtrack.album_id = Album.album_id' , 'left' );
    $query = $this->db->get ();
    return $query->result ();
 }

if u want to get specific album data use

  function get_album_data($album_id) {

    $this->db->select ( '*' ); 
    $this->db->from ( 'Album' );
    $this->db->join ( 'Category', 'Category.cat_id = Album.cat_id' , 'left' );
    $this->db->join ( 'Soundtrack', 'Soundtrack.album_id = Album.album_id' , 'left' );
    $this->db->where ( 'Album.album_id', $album_id);
    $query = $this->db->get ();
    return $query->result ();
 }

you can use rjust string method of python syntax: string.rjust(length, fillchar) fillchar is optional

and for your Question you acn write like this

'0b'+ '1'.rjust(8,'0)

so it wil be '0b00000001'

Put the width and height in separate attributes, with no unit:

Another Option:

<!--[if gte mso 9]>
<style type="text/css">
img.header { width: 600px; } /* or something like that */

Use this to convert String to Blob. Where connection is the connection to db object.

    String strContent = s;
    byte[] byteConent = strContent.getBytes();
    Blob blob = connection.createBlob();//Where connection is the connection to db object. 
    blob.setBytes(1, byteContent);

In code to load resource in the executing assembly where my image 'Freq.png' was in the folder "Icons" and defined as "Resource".

        this.Icon = new BitmapImage(new Uri(@"pack://application:,,,/" 
             + Assembly.GetExecutingAssembly().GetName().Name 
             + ";component/" 
             + "Icons/Freq.png", UriKind.Absolute)); 

I also made a function if anybody would like it...

/// <summary>
/// Load a resource WPF-BitmapImage (png, bmp, ...) from embedded resource defined as 'Resource' not as 'Embedded resource'.
/// </summary>
/// <param name="pathInApplication">Path without starting slash</param>
/// <param name="assembly">Usually 'Assembly.GetExecutingAssembly()'. If not mentionned, I will use the calling assembly</param>
/// <returns></returns>
public static BitmapImage LoadBitmapFromResource(string pathInApplication, Assembly assembly = null)
{
    if (assembly == null)
    {
        assembly = Assembly.GetCallingAssembly();
    }

    if (pathInApplication[0] == '/')
    {
        pathInApplication = pathInApplication.Substring(1);
    }
    return new BitmapImage(new Uri(@"pack://application:,,,/" + assembly.GetName().Name + ";component/" + pathInApplication, UriKind.Absolute)); 
}

Usage:

        this.Icon = ResourceHelper.LoadBitmapFromResource("Icons/Freq.png");

You can use the LocalForward directive in your host yam section of ~/.ssh/config:

Build on what you already know and have a look at lot of job adverts. E.g I have seen jobs asking for WinForms/WPF AND electronics for the writing of a UI to control a custom bit of hardware.

You may find the “robotics” .net toolkit interesting.

.Net is now too big for anyone to learn both WEB and Desktop so you have to decide the way you are going to go. Web has lots more jobs, but there are very few people with good desktop stills.

OnClick is triggered when the user releases the button. But if you still want to use the TouchListener you need to add it in code. It's just:

myView.setOnTouchListener(new View.OnTouchListener()
{
    // Implementation;
});

The .css() function doesn't queue behind running animations, it's instantaneous.

To match the behaviour that you're after, you'd need to do the following:

$(document).ready(function() {
  $("button").mouseover(function() {
    var p = $("p#44.test").css("background-color", "yellow");
    p.hide(1500).show(1500);
    p.queue(function() {
      p.css("background-color", "red");
    });
  });
});

The .queue() function waits for running animations to run out and then fires whatever's in the supplied function.

From MSDN

@@IDENTITY, SCOPE_IDENTITY, and IDENT_CURRENT are similar functions in that they return the last value inserted into the IDENTITY column of a table.

@@IDENTITY and SCOPE_IDENTITY will return the last identity value generated in any table in the current session. However, SCOPE_IDENTITY returns the value only within the current scope; @@IDENTITY is not limited to a specific scope.

IDENT_CURRENT is not limited by scope and session; it is limited to a specified table. IDENT_CURRENT returns the identity value generated for a specific table in any session and any scope. For more information, see IDENT_CURRENT.

• IDENT_CURRENT is a function which takes a table as a argument.
• @@IDENTITY may return confusing result when you have an trigger on the table
• SCOPE_IDENTITY is your hero most of the time.

Extending Adam Thomas answer you can easily make this directive more generic by adding input argument with custom regexp:

var app = angular.module('myApp', []);

app.controller('MainCtrl', function($scope) {
});

app.directive('validInput', function() {
  return {
    require: '?ngModel',
    scope: {
      "inputPattern": '@'
    },
    link: function(scope, element, attrs, ngModelCtrl) {

      var regexp = null;

      if (scope.inputPattern !== undefined) {
        regexp = new RegExp(scope.inputPattern, "g");
      }

      if(!ngModelCtrl) {
        return;
      }

      ngModelCtrl.$parsers.push(function(val) {
        if (regexp) {
          var clean = val.replace(regexp, '');
          if (val !== clean) {
            ngModelCtrl.$setViewValue(clean);
            ngModelCtrl.$render();
          }
          return clean;
        }
        else {
          return val;
        }

      });

      element.bind('keypress', function(event) {
        if(event.keyCode === 32) {
          event.preventDefault();
        }
      });
    }
}});

Well, to do it with eloquent you would do:

Blog:all();

From within your Model you do:

return DB::table('posts')->get();

You can also get this warning when performing a segue from a view controller that is embedded in a container. The correct solution is to use segue from the parent of container, not from container's view controller.

I have another solution. If Alpha and Beta are your only extra class then why not make a static variable with the image of the class.

Like in Alpha class :

public class Alpha{
        public static Alpha alpha;
        public Alpha(){
                this.alpha = this;
}

Now you you can call the function in Beta class by just using these lines :

new Alpha();
Alpha.alpha.DoSomethingAlpha();

If you do not mind having to compile/generate the file then you could use a pre processing technique. This gives you the power of the generate but results in a clean Verilog file which is often easier to debug and leads to less simulator issues.

I use RubyIt to generate verilog files from templates using ERB (Embedded Ruby).

parameter ROWBITS = <%= ROWBITS %> ;
always @(posedge sysclk) begin
  <% (0...ROWBITS).each do |addr| -%>
    temp[<%= addr %>] <= 1'b0;
  <% end -%>
end

Generating the module_name.v file with :

$ ruby_it --parameter ROWBITS=4 --outpath ./ --file ./module_name.rv

The generated module_name.v

parameter ROWBITS = 4 ;
always @(posedge sysclk) begin
  temp[0] <= 1'b0;
  temp[1] <= 1'b0;
  temp[2] <= 1'b0;
  temp[3] <= 1'b0;
end

            }
        });

Deleting the existing global.asax file and adding a new one, clears out this error. This has worked for me many times.

here is more simple way without StartCoroutine:

float t = 0f;
float waittime = 1f;

and inside Update/FixedUpdate:

if (t < 0){
    t += Time.deltaTIme / waittime;
    yield return t;
}

There is a difference, but subtle. Look at it this way: struct Foo introduces a new type. The second one creates an alias called Foo (and not a new type) for an unnamed struct type.

7.1.3 The typedef specifier

1 [...]

A name declared with the typedef specifier becomes a typedef-name. Within the scope of its declaration, a typedef-name is syntactically equivalent to a keyword and names the type associated with the identifier in the way described in Clause 8. A typedef-name is thus a synonym for another type. A typedef-name does not introduce a new type the way a class declaration (9.1) or enum declaration does.

8 If the typedef declaration defines an unnamed class (or enum), the first typedef-name declared by the declaration to be that class type (or enum type) is used to denote the class type (or enum type) for linkage purposes only (3.5). [ Example:

typedef struct { } *ps, S; // S is the class name for linkage purposes

So, a typedef always is used as an placeholder/synonym for another type.

EF 6

In my scenario, Entity Framework was not picking up the newly updated data. The reason might be the data was updated outside of its scope. Refreshing data after fetching resolved my issue.

private void RefreshData(DBEntity entity)
{
    if (entity == null) return;

    ((IObjectContextAdapter)DbContext).ObjectContext.RefreshAsync(RefreshMode.StoreWins, entity);
}

private void RefreshData(List<DBEntity> entities)
{
    if (entities == null || entities.Count == 0) return;

    ((IObjectContextAdapter)DbContext).ObjectContext.RefreshAsync(RefreshMode.StoreWins, entities);
}

There is also a slightly simpler way of removing the value.

mydropdownid.Items.Remove("Chicago"); 
<dropdown id=mydropdown .....>

values

• Florida
• Texas
• Utah
• Chicago

You can take a look here for a longer list of screen sizes and respective media queries.

Or go for Bootstrap media queries:

/* Large desktop */
@media (min-width: 1200px) { ... }

/* Portrait tablet to landscape and desktop */
@media (min-width: 768px) and (max-width: 979px) { ... }

/* Landscape phone to portrait tablet */
@media (max-width: 767px) { ... }

/* Landscape phones and down */
@media (max-width: 480px) { ... }

Additionally you might wanty to take a look at Foundation's media queries with the following default settings:

// Media Queries

Try rerunning the pod and running

 kubectl get pods --watch

to watch the status of the pod as it progresses.

In my case, I would only see the end result, 'CrashLoopBackOff,' but the docker container ran fine locally. So I watched the pods using the above command, and I saw the container briefly progress into an OOMKilled state, which meant to me that it required more memory.

We can replace the code in the AndroidManifest file in the application tag

("Jesse" or "jesse")

The above expression tests whether or not "Jesse" evaluates to True. If it does, then the expression will return it; otherwise, it will return "jesse". The expression is equivalent to writing:

"Jesse" if "Jesse" else "jesse"

Because "Jesse" is a non-empty string though, it will always evaluate to True and thus be returned:

>>> bool("Jesse")  # Non-empty strings evaluate to True in Python
True
>>> bool("")  # Empty strings evaluate to False
False
>>>
>>> ("Jesse" or "jesse")
'Jesse'
>>> ("" or "jesse")
'jesse'
>>>

This means that the expression:

name == ("Jesse" or "jesse")

is basically equivalent to writing this:

name == "Jesse"

In order to fix your problem, you can use the in operator:

# Test whether the value of name can be found in the tuple ("Jesse", "jesse")
if name in ("Jesse", "jesse"):

Or, you can lowercase the value of name with str.lower and then compare it to "jesse" directly:

# This will also handle inputs such as "JeSSe", "jESSE", "JESSE", etc.
if name.lower() == "jesse":

Isn't this a much simpler solution, if I correctly understand the question, of course.

I want to load email addresses that are in a table called "spam" into a variable.

select email from spam

produces the following list, say:

.accountant
.bid
.buiilldanything.com
.club
.cn
.cricket
.date
.download
.eu

To load into the variable @list:

declare @list as varchar(8000)
set @list += @list (select email from spam)

@list may now be INSERTed into a table, etc.

I hope this helps.

To use it for a .csv file or in VB, spike the code:

declare @list as varchar(8000)
set @list += @list (select '"'+email+',"' from spam)
print @list

and it produces ready-made code to use elsewhere:

".accountant,"
".bid,"
".buiilldanything.com,"
".club,"
".cn,"
".cricket,"
".date,"
".download,"
".eu,"

One can be very creative.

Thanks

Partial mocking of a class is also supported via Spy in mockito

List list = new LinkedList();
List spy = spy(list);

//optionally, you can stub out some methods:
when(spy.size()).thenReturn(100);

//using the spy calls real methods
spy.add("one");
spy.add("two");

//size() method was stubbed - 100 is printed
System.out.println(spy.size());

Check the 1.10.19 and 2.7.22 docs for detailed explanation.

As you see from the other post you have linked, there isn't a way for the app to know if the user has left a review or not. And for good reason.

Think about it, if an app could tell if the user has left a review or not, the developer could restrict certain features that would only be unlocked if the user leaves a 5/5 rating. This would lead the other users of Google Play to not trust the reviews and would undermine the rating system.

The alternative solutions I have seen is that the app reminds the user to submit a rating whenever the app is opened a specific number of times, or a set interval. For example, on every 10th time the app is opened, ask the user to leave a rating and provide a "already done" and "remind me later" button. Keep showing this message if the user has chosen to remind him/her later. Some other apps developers show this message with an increasing interval (like, 5, 10, 15nth time the app is opened), because if a user hasn't left a review on the, for example, 100th time the app was opened, it's probably likely s/he won't be leaving one.

This solution isn't perfect, but I think it's the best you have for now. It does lead you to trust the user, but realize that the alternative would mean a potentially worse experience for everyone in the app market.

Just a shot in the dark(since you did not share the compiler initialization code with us): the way you retrieve the compiler causes the issue. Point your JRE to be inside the JDK as unlike jdk, jre does not provide any tools hence, results in NPE.

I've face this problem, i fixed it by deleting the emulator then created a new one with higher API level.

The short answer is the iPhone supports H.264 video, High profile and AAC audio, in container formats .mov, .mp4, or MPEG Segment .ts. MPEG Segment files are used for HTTP Live Streaming.

• For maximum compatibility with Android and desktop browsers, use H.264 + AAC in an .mp4 container.
• For extended length videos longer than 10 minutes you must use HTTP Live Streaming, which is H.264 + AAC in a series of small .ts container files (see App Store Review Guidelines rule 2.5.7).

Video

On the iPhone, H.264 is the only game in town. [1]

There are several different feature tiers or "profiles" available in H.264. All modern iPhones (3GS and above) support the High profile. These profiles are basically three different levels of algorithm "tricks" used to compress the video. More tricks give better compression, but require more CPU or dedicated hardware to decode. This is a table that lists the differences between the different profiles.

[1] Interestingly, Apple's own Facetime uses the newer H.265 (HEVC) video codec. However right now (August 2017) there is no Apple-provided library that gives access to a HEVC codec to developers. This is expected to change at some point.

In talking about what video format the iPhone supports, a distinction should be made between what the hardware can support, and what the (much lower) limits are for playback when streaming over a network.

The only data given about hardware video support by Apple about the current generation of iPhones (SE, 6S, 6S Plus, 7, 7 Plus) is that they support

4K [3840x2160] video recording at 30 fps

1080p [1920x1080] HD video recording at 30 fps or 60 fps.

Obviously the phone can play back what it can record, so we can guess that 3840x2160 at 30 fps and 1920x1080 at 60 fps represent design limits of the phone. In addition, the screen size on the 6S Plus and 7 Plus is 1920x1080. So if you're interested in playback on the phone, it doesn't make sense to send over more pixels then the screen can draw.

However, streaming video is a different matter. Since networks are slow and video is huge, it's typical to use lower resolutions, bitrates, and frame rates than the device's theoretical maximum.

The most detailed document giving recommendations for streaming is TN2224 Best Practices for Creating and Deploying HTTP Live Streaming Media for Apple Devices. Figure 3 in that document gives a table of recommended streaming parameters:

This table is from May 2016.

As you can see, Apple recommends the relatively low resolution of 768x432 as the highest recommended resolution for streaming over a cellular network. Of course this is just a recommendation and YMMV.

Audio

The question is about video, but that video generally has one or more audio tracks with it. The iPhone supports a few audio formats, but the most modern and by far most widely used is AAC. The iPhone 7 / 7 Plus, 6S Plus / 6S, SE all support AAC bitrates of 8 to 320 Kbps.

Container

The audio and video tracks go inside a container. The purpose of the container is to combine (interleave) the different tracks together, to store metadata, and to support seeking. The iPhone supports

1. QuickTime .mov,
2. MP4, and
3. MPEG-TS.

The .mov and .mp4 file formats are closely related (.mp4 is in fact based on .mov), however .mp4 is an ISO standard that has much wider support.

As noted above, you have to use MPEG-TS for videos longer than 10 minutes.

var now = DateTime.Now;
var first = new DateTime(now.Year, now.Month, 1);
var last = first.AddMonths(1).AddDays(-1);

You could also use DateTime.DaysInMonth method:

var last = new DateTime(now.Year, now.Month, DateTime.DaysInMonth(now.Year, now.Month));

The best way to decide questions like this to benchmark them:

use strict;
use warnings;
use Benchmark qw(:all);

our @input_array = (0..1000);

my $a = sub {
    my @array = @{[ @input_array ]};

       die unless $index == $element;
       $index++;
    }
};

my $b = sub {
    my @array = @{[ @input_array ]};
    my $index = 0;
    while (defined(my $element = shift @array)) {
       die unless $index == $element;
       $index++;
    }
};

my $c = sub {

    my $index = 0;
    while (scalar(@array) !=0) {
       my $element = shift(@array);
       die unless $index == $element;
       $index++;
    }
};

my $d = sub {
    my @array = @{[ @input_array ]};
    foreach my $index (0.. $#array) {
       my $element = $array[$index];
       die unless $index == $element;
    }
};

my $e = sub {
    my @array = @{[ @input_array ]};
    for (my $index = 0; $index <= $#array; $index++) {
       my $element = $array[$index];
       die unless $index == $element;
    }
};

my $f = sub {
    my @array = @{[ @input_array ]};
    while (my ($index, $element) = each @array) {
       die unless $index == $element;
    }
};

my $count;
timethese($count, {
   '1' => $a,
   '2' => $b,
   '3' => $c,
   '4' => $d,
   '5' => $e,
   '6' => $f,
});

And running this on perl 5, version 24, subversion 1 (v5.24.1) built for x86_64-linux-gnu-thread-multi

I get:

Benchmark: running 1, 2, 3, 4, 5, 6 for at least 3 CPU seconds...
         1:  3 wallclock secs ( 3.16 usr +  0.00 sys =  3.16 CPU) @ 12560.13/s (n=39690)
         2:  3 wallclock secs ( 3.18 usr +  0.00 sys =  3.18 CPU) @ 7828.30/s (n=24894)

         6:  3 wallclock secs ( 3.12 usr +  0.00 sys =  3.12 CPU) @ 5653.53/s (n=17639)

So the 'foreach (@Array)' is about twice as fast as the others. All the others are very similar.

@ikegami also points out that there are quite a few differences in these implimentations other than speed.

You can also do this with the ol' good method :

String inputLine = "test123";
String translatedString = null;
char[] stringArray = inputLine.toCharArray();
for(int i=0;i<stringArray.length;i++){
      translatedString += Integer.toBinaryString((int) stringArray[i]);
}

With a foreach:

let itemYouWant = null;
array.forEach((item) => {
    if (item.name === 'string 1') {
        itemYouWant = item;
    }
});
console.log(itemYouWant);

Looks like recentish versions of Git (I'm on git v2.20) allow one to simply say

git fetch --prune --prune-tags

Much cleaner!

https://git-scm.com/docs/git-fetch#_pruning

You can also configure git to always prune tags when fetching:

git config fetch.pruneTags true

If you only want to prune tags when fetching from a specific remote, you can use the remote.<remote>.pruneTags option. For example, to always prune tags when fetching from origin but not other remotes,

git config remote.origin.pruneTags true

If you don't want to install Homebrew only for install Maven you could simply do this:

1. Download the binary Maven and extract the zip

2. Launch the Terminal and type this command:

   sudo ln -s /path_to_maven_folder/bin/mvn /usr/bin/mvn

You can find more details on this post.

foreach($months as $key => $month){

        echo "<div style ='font:11px/21px Arial,tahoma,sans-serif;color:#ff0000'> Movie List for $key 2013</div>";
    }
}

var datep = $('#datepicker').val();

if(Date.parse(datep)-Date.parse(new Date())<0)
{

I did found a way to convert (even bad) html into well formed XML. I started to base this on the DOM loadHTML function. However during time several issues occurred and I optimized and added patches to correct side effects.

  function tryToXml($dom,$content) {
    if(!$content) return false;

    // xml well formed content can be loaded as xml node tree
    $fragment = $dom->createDocumentFragment();
    // wonderfull appendXML to add an XML string directly into the node tree!

    // aappendxml will fail on a xml declaration so manually skip this when occurred
    if( substr( $content,0, 5) == '<?xml' ) {
      $content = substr($content,strpos($content,'>')+1);
      if( strpos($content,'<') ) {
        $content = substr($content,strpos($content,'<'));
      }
    }

    // if appendXML is not working then use below htmlToXml() for nasty html correction
    if(!@$fragment->appendXML( $content )) {
      return $this->htmlToXml($dom,$content);
    }

    return $fragment;
  }



  // convert content into xml
  // dom is only needed to prepare the xml which will be returned
  function htmlToXml($dom, $content, $needEncoding=false, $bodyOnly=true) {

    // no xml when html is empty
    if(!$content) return false;

    // real content and possibly it needs encoding
    if( $needEncoding ) {
      // no need to convert character encoding as loadHTML will respect the content-type (only)
      $content =  '<meta http-equiv="Content-Type" content="text/html;charset='.$this->encoding.'">' . $content;
    }

    // return a dom from the content
    $domInject = new DOMDocument("1.0", "UTF-8");
    $domInject->preserveWhiteSpace = false;
    $domInject->formatOutput = true;

    // html type
    try {
      @$domInject->loadHTML( $content );
    } catch(Exception $e){
      // do nothing and continue as it's normal that warnings will occur on nasty HTML content
    }
        // to check encoding: echo $dom->encoding
        $this->reworkDom( $domInject );

    if( $bodyOnly ) {
      $fragment = $dom->createDocumentFragment();

      // retrieve nodes within /html/body
      foreach( $domInject->documentElement->childNodes as $elementLevel1 ) {
       if( $elementLevel1->nodeName == 'body' and $elementLevel1->nodeType == XML_ELEMENT_NODE ) {
         foreach( $elementLevel1->childNodes as $elementInject ) {
           $fragment->insertBefore( $dom->importNode($elementInject, true) );
         }
        }
      }
    } else {
      $fragment = $dom->importNode($domInject->documentElement, true);
    }

    return $fragment;
  }



    protected function reworkDom( $node, $level = 0 ) {

        // start with the first child node to iterate
        $nodeChild = $node->firstChild;

        while ( $nodeChild )  {
            $nodeNextChild = $nodeChild->nextSibling;

            switch ( $nodeChild->nodeType ) {
                case XML_ELEMENT_NODE:
                    // iterate through children element nodes
                    $this->reworkDom( $nodeChild, $level + 1);
                    break;
                case XML_TEXT_NODE:
                case XML_CDATA_SECTION_NODE:
                    // do nothing with text, cdata
                    break;
                case XML_COMMENT_NODE:
                    // ensure comments to remove - sign also follows the w3c guideline
                    $nodeChild->nodeValue = str_replace("-","_",$nodeChild->nodeValue);
                    break;
                case XML_DOCUMENT_TYPE_NODE:  // 10: needs to be removed
                case XML_PI_NODE: // 7: remove PI
                    $node->removeChild( $nodeChild );
                    $nodeChild = null; // make null to test later
                    break;
                case XML_DOCUMENT_NODE:
                    // should not appear as it's always the root, just to be complete
                    // however generate exception!
                case XML_HTML_DOCUMENT_NODE:
                    // should not appear as it's always the root, just to be complete
                    // however generate exception!
                default:
                    throw new exception("Engine: reworkDom type not declared [".$nodeChild->nodeType. "]");
            }
            $nodeChild = $nodeNextChild;
        } ;
    }

Now this also allows to add more html pieces into one XML which I needed to use myself. In general it can be used like this:

        $c='<p>test<font>two</p>';
    $dom=new DOMDocument('1.0', 'UTF-8');

$n=$dom->appendChild($dom->createElement('info')); // make a root element

if( $valueXml=tryToXml($dom,$c) ) {
  $n->appendChild($valueXml);
}
    echo '<pre/>'. htmlentities($dom->saveXml($n)). '</pre>';

In this example '<p>test<font>two</p>' will nicely be outputed in well formed XML as '<info><p>test<font>two</font></p></info>'. The info root tag is added as it will also allow to convert '<p>one</p><p>two</p>' which is not XML as it has not one root element. However if you html does for sure have one root element then the extra root <info> tag can be skipped.

With this I'm getting real nice XML out of unstructured and even corrupted HTML!

I hope it's a bit clear and might contribute to other people to use it.

I know it's an old post but I had the same issue today, what I did is simple : changing my script that send my playbook from my local host to the server, before sending it with maven command, I did this :

cat common_vars.yml > vars.yml
cat snapshot_vars.yml >> vars.yml
# or 
#cat release_vars.yml >> vars.yml
mvn ....

MySQLi stands for MySQL improved. It's an object-oriented interface to the MySQL bindings which makes things easier to use. It also offers support for prepared statements (which are very useful). If you're on PHP 5 use MySQLi.

You can add the script tags like how we use in the asp.net while doing client side validations like below.

@{
    ViewBag.Title = "Index";
}

<h2>Index</h2>
<script type="text/javascript" src="~/Scripts/jquery-3.1.1.min.js"></script>
<script type="text/javascript">
    $(function () {
       //Your code
    });
</script>

Converting to a list without using the keys method makes it more readable:

list(newdict)

and, when looping through dictionaries, there's no need for keys():

for key in newdict:
    print key

unless you are modifying it within the loop which would require a list of keys created beforehand:

for key in list(newdict):
    del newdict[key]

On Python 2 there is a marginal performance gain using keys().

V8.NET is a new kid on the block (as of April 2013) that more closely wraps the native V8 engine functionality. It allows for more control over the implementation.

Assuming the renderDetailItem method has the following signature...

(rowData, sectionID, rowID, highlightRow) 

Try doing this...

<TouchableHighlight key={rowID} underlayColor='#dddddd'>

There is a KeyValuePair built-in type. As a matter of fact, this is what the IDictionary is giving you access to when you iterate in it.

Also, this structure is hardly a tree, finding a more representative name might be a good exercise.

If you run pub build --mode=debug the build directory contains the application without symlinks. The Dart code should be retained when --mode=debug is used.

Here is some discussion going on about this topic too Dart and it's place in Rails Assets Pipeline

I had the same problem of "gpg: keyserver timed out" with a couple of different servers. Finally, it turned out that I didn't need to do that manually at all. On a Debian system, the simple solution which fixed it was just (as root or precede with sudo):

aptitude install debian-archive-keyring

In case it is some other keyring you need, check out

apt-cache search keyring | grep debian

My squeeze system shows all these:

debian-archive-keyring       - GnuPG archive keys of the Debian archive
debian-edu-archive-keyring   - GnuPG archive keys of the Debian Edu archive
debian-keyring               - GnuPG keys of Debian Developers
debian-ports-archive-keyring - GnuPG archive keys of the debian-ports archive
emdebian-archive-keyring     - GnuPG archive keys for the emdebian repository

Maybe you're looking for something like this:

def tableize(df):
    if not isinstance(df, pd.DataFrame):
        return
    df_columns = df.columns.tolist() 
    max_len_in_lst = lambda lst: len(sorted(lst, reverse=True, key=len)[0])
    align_center = lambda st, sz: "{0}{1}{0}".format(" "*(1+(sz-len(st))//2), st)[:sz] if len(st) < sz else st
    align_right = lambda st, sz: "{0}{1} ".format(" "*(sz-len(st)-1), st) if len(st) < sz else st
    max_col_len = max_len_in_lst(df_columns)
    max_val_len_for_col = dict([(col, max_len_in_lst(df.iloc[:,idx].astype('str'))) for idx, col in enumerate(df_columns)])
    col_sizes = dict([(col, 2 + max(max_val_len_for_col.get(col, 0), max_col_len)) for col in df_columns])
    build_hline = lambda row: '+'.join(['-' * col_sizes[col] for col in row]).join(['+', '+'])
    build_data = lambda row, align: "|".join([align(str(val), col_sizes[df_columns[idx]]) for idx, val in enumerate(row)]).join(['|', '|'])
    hline = build_hline(df_columns)
    out = [hline, build_data(df_columns, align_center), hline]
    for _, row in df.iterrows():
        out.append(build_data(row.tolist(), align_right))
    out.append(hline)
    return "\n".join(out)


df = pd.DataFrame([[1, 2, 3], [11111, 22, 333]], columns=['a', 'b', 'c'])
print tableize(df)

Output:
+-------+----+-----+
|    a  |  b |   c |
+-------+----+-----+
|     1 |  2 |   3 |
| 11111 | 22 | 333 |
+-------+----+-----+

Shortcut from JavaDoc:

boolean contains(Object o)

Returns true if this list contains the specified element. More formally, returns true if and only if this list contains at least one element e such that (o==null ? e==null : o.equals(e))

I found this will have git ignore temporary files created by vim:

[._]*.s[a-w][a-z]

It can also be viewed here.

The :nth-child() and :nth-of-type() pseudo-classes allows you to select elements with a formula.

The syntax is :nth-child(an+b), where you replace a and b by numbers of your choice.

For instance, :nth-child(3n+1) selects the 1st, 4th, 7th etc. child.

td:nth-child(3n+1) {  
  /* your stuff here */
}

:nth-of-type() works the same, except that it only considers element of the given type ( in the example).

I can do like that (sorry it's c# not java but it's not a problem...) :

private int iValue = 1234567890;

function void MyTest()
{
    Intent oIntent = new Intent (this, typeof(Camera2Activity));
    Bundle oBundle = new Bundle();
    oBundle.PutInt("MYVALUE", iValue); //=> 1234567890
    oIntent.PutExtras (oBundle);
    iRequestCode = 1111;
    StartActivityForResult (oIntent, 1111);
}

AND IN YOUR ACTIVITY FOR RESULT

private int iValue = 0;

protected override void OnCreate(Bundle bundle)
{
    Bundle oBundle =  Intent.Extras;
    if (oBundle != null)
    {
        iValue = oBundle.GetInt("MYVALUE", 0);
        //=>1234567890
    }
}

private void FinishActivity(bool bResult)
{
    Intent oIntent = new Intent();
    Bundle oBundle = new Bundle();
    oBundle.PutInt("MYVALUE", iValue);//=>1234567890
    oIntent.PutExtras(oBundle);
    if (bResult)
        {
            SetResult (Result.Ok, oIntent);
        }
    else
        SetResult(Result.Canceled, oIntent);
    GC.Collect();
    Finish();
}

FINALLY

protected override void OnActivityResult(int iRequestCode, Android.App.Result oResultCode, Intent oIntent)
{
    base.OnActivityResult (iRequestCode, oResultCode, oIntent);
    iValue = oIntent.Extras.GetInt("MYVALUE", -1); //=> 1234567890
}

A more modern version would be to use something akin to the following...

require 'rubygems'
puts Gem::Specification.all().map{|g| [g.name, g.version.to_s].join('-') }

NOTE: very similar the first part of an answer by Evgeny... but due to page formatting, it's easy to miss.

public class ResourceQuery

   public int OptionalParam2 { get; set; }
}

public class SampleResourceController : ApiController
{
    public SampleResourceModel Get([FromUri] ResourceQuery query)
    {
        // action
    }
}

create an intent and set an action for it while passing the url to the intent

yourbtn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                String theurl = "http://google.com";
                Uri urlstr = Uri.parse(theurl);
                Intent urlintent = new Intent();
                urlintent.setData(urlstr);
                urlintent.setAction(Intent.ACTION_VIEW);
                startActivity(urlintent);

$(document).on( "keydown",  keyPressed);

function keyPressed (e){
    e = e || window.e;
    var newchar = e.which || e.keyCode;
    alert(newchar)
}

other way(unicode string even):

$res = array();
$str = 'test 1234 555 2.7 string ..... 2.2 3.3';
$str = preg_replace("/[^0-9\.]/", " ", $str);
$str = trim(preg_replace('/\s+/u', ' ', $str));
$arr = explode(' ', $str);
for ($i = 0; $i < count($arr); $i++) {
    if (is_numeric($arr[$i])) {
        $res[] = $arr[$i];
    }
}
print_r($res); //Array ( [0] => 1234 [1] => 555 [2] => 2.7 [3] => 2.2 [4] => 3.3 ) 

To do this in the layout.xml file:

android:textStyle

Examples:

android:textStyle="bold|italic"

Programmatically the method is:

setTypeface(Typeface tf)

Sets the typeface and style in which the text should be displayed. Note that not all Typeface families actually have bold and italic variants, so you may need to use setTypeface(Typeface, int) to get the appearance that you actually want.

If it does not work by using the click() method like suggested in the accepted answer, then you can try this:

//trigger second button
$("#second").mousedown();
$("#second").mouseup();

I had this issue occurring with mailto: and tel: links inside an iframe (in Chrome, not a webview). Clicking the links would show the grey "page not found" page and inspecting the page showed it had a ERR_UNKNOWN_URL_SCHEME error.

Adding target="_blank", as suggested by this discussion of the issue fixed the problem for me.

For php.ini 5.6 version (check version using php -v)

;extension=php_intl.dll ; remove semicolon and keep like this extension=php_intl.dll

For php.ini 7.* version

Though both Inheritance and Composition provides code reusablility, main difference between Composition and Inheritance in Java is that Composition allows reuse of code without extending it but for Inheritance you must extend the class for any reuse of code or functionality. Another difference which comes from this fact is that by using Composition you can reuse code for even final class which is not extensible but Inheritance cannot reuse code in such cases. Also by using Composition you can reuse code from many classes as they are declared as just a member variable, but with Inheritance you can reuse code form just one class because in Java you can only extend one class, because multiple Inheritance is not supported in Java. You can do this in C++ though because there one class can extend more than one class. BTW, You should always prefer Composition over Inheritance in Java, its not just me but even Joshua Bloch has suggested in his book

I had to use os.system, since subprocess was giving me a memory error for larger tasks. Reference for this problem here. So, in order to get the output of the os.system command I used this workaround:

import os

batcmd = 'dir'
result_code = os.system(batcmd + ' > output.txt')
if os.path.exists('output.txt'):
    fp = open('output.txt', "r")
    output = fp.read()
    fp.close()
    os.remove('output.txt')
    print(output)

My problem was not listed, it was something so silly ..... The table that has the FK as PK was a composite PK that was declared like this: primary key (CNPJ, CEP) I wanted the CEP field to be FK in another table and I was stuck in this error, the moral of the story just inverted the code above for Primary key (CEP, CNPJ) and it worked. Get tip their friends.

If your CSS html element has the following overflow markup, scrollTop will not function.

html {
    overflow-x: hidden;
    overflow-y: hidden;
}

To allow scrollTop to scroll, modify your markup remove overflow markup from the html element and append to a body element.

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

Besides put all your assets in the public folder, you can use the HTML::image() Method, and only needs an argument which is the path to the image, relative on the public folder, as well:

{{ HTML::image('imgs/picture.jpg') }}

Which generates the follow HTML code:

<img src="http://localhost:8000/imgs/picture.jpg">

The link to other elements of HTML::image() Method: http://laravel-recipes.com/recipes/185/generating-an-html-image-element

Some time in the future, we can write it like this:

li:nth-child(2) {
    rotate: 15deg;
    translate:-20px 0px;        
}

This will become especially useful when applying individual classes on an element:

<div class="teaser important"></div>

.teaser{rotate:10deg;}
.important{scale:1.5 1.5;}

This syntax is defined in the in-progress CSS Transforms Level 2 specification, but can't find anything about current browser support other then chrome canary. Hope some day i'll come back and update browser support here ;)

Found the info in this article which you might want to check out regarding workarounds for current browsers.

Your stored procedures work as coded. The problem is with the last line, it is unable to invoke either of your stored procedures.

Three choices in SQL*Plus are: call, exec, and an anoymous PL/SQL block.

call appears to be a SQL keyword, and is documented in the SQL Reference. http://download.oracle.com/docs/cd/B19306_01/server.102/b14200/statements_4008.htm#BABDEHHG The syntax diagram indicates that parentesis are required, even when no arguments are passed to the call routine.

CALL test_sp_1();

An anonymous PL/SQL block is PL/SQL that is not inside a named procedure, function, trigger, etc. It can be used to call your procedure.

BEGIN
    test_sp_1;
END;
/

Exec is a SQL*Plus command that is a shortcut for the above anonymous block. EXEC <procedure_name> will be passed to the DB server as BEGIN <procedure_name>; END;

Full example:

SQL> SET SERVEROUTPUT ON
SQL> CREATE OR REPLACE PROCEDURE test_sp 
  2  AS 
  3  BEGIN 
  4      DBMS_OUTPUT.PUT_LINE('Test works'); 
  5  END;
  6  /

Procedure created.

SQL> CREATE OR REPLACE PROCEDURE test_sp_1 
  2  AS

First include the file in head tag of html , then call the function in script tags under body tags e.g.

Js file function to be called

function tryMe(arg) {
    document.write(arg);
}

HTML FILE

<!DOCTYPE html>
<html>
<head>
    <script type="text/javascript" src='object.js'> </script>
    <title>abc</title><meta charset="utf-8"/>
</head>
<body>
    <script>
    tryMe('This is me vishal bhasin signing in');
    </script>
</body>
</html>

This is happening because they're all referencing the same i variable, which is changing every loop, and left as 10 at the end of the loop. You can resolve it using a closure like this:

link.onclick = function(j) { return function() { onClickLink(j+''); }; }(i);

You can give it a try here

Or, make this be the link you clicked in that handler, like this:

link.onclick = function(j) { return function() { onClickLink.call(this, j); }; }(i);

You can try that version here

In your regex you need to escape the dot "\." or use it inside a character class "[.]", as it is a meta-character in regex, which matches any character.

Also, you need \w+ instead of \w to match one or more word characters.

Now, if you want the test.this content, then split is not what you need. split will split your string around the test.this. For example:

>>> re.split(r"\b\w+\.\w+@", s)
['blah blah blah ', 'gmail.com blah blah']

You can use re.findall:

>>> re.findall(r'\w+[.]\w+(?=@)', s)   # look ahead
['test.this']
>>> re.findall(r'(\w+[.]\w+)@', s)     # capture group
['test.this']

As android doesn't support such a thing, you can do it manually with FontCreator. It has good options for font modifying. I used this tool to build a custom font, even if it takes some times but you can always use it in your projects.

just install requirements:

sudo apt-get install libxml2-dev libxslt-dev python-dev

Now, you can install it with pip package management tool:

pip install lxml

For python3 users:

sudo apt-get install libxml2-dev libxslt-dev python3-dev

pip3 install lxml

SELECT d1.Short_Code 
FROM domain1 d1

I wanted to try a simple class outside IDE and stuff. So downloaded selenium zip from website and run the class like this:

java -cp selenium-2.50.1/*:selenium-2.50.1/libs/*:. my/package/MyClass <params>

I had the issue that I initially used lib instead of libs. I didn't need to add selenium standalone jar. This is Java 8 that understands wildcards in classpath. I think java 7 would also do.

It will definitely cost you more space & bandwidth if you want to use base64 encoded images. However if your site has a lot of small images you can decrease the page loading time by encoding your images to base64 and placing them into html. In this way, the client browser wont need to make a lot of connections to the images, but will have them in html.

Oracle 12c

We now finally have IDENTITY columns like many other databases, in case of which a sequence is auto-generated behind the scenes. This solution is much faster than a trigger-based one as can be seen in this blog post.

So, your table creation would look like this:

CREATE TABLE qname
(
    qname_id integer GENERATED BY DEFAULT AS IDENTITY (START WITH 1) NOT NULL PRIMARY KEY,
    qname    VARCHAR2(4000) NOT NULL -- CONSTRAINT qname_uk UNIQUE
);

Oracle 11g and below

According to the documentation, you cannot do that:

Restriction on Default Column Values A DEFAULT expression cannot contain references to PL/SQL functions or to other columns, the pseudocolumns CURRVAL, NEXTVAL, LEVEL, PRIOR, and ROWNUM, or date constants that are not fully specified.

The standard way to have "auto increment" columns in Oracle is to use triggers, e.g.

CREATE OR REPLACE TRIGGER my_trigger
  BEFORE INSERT 
  ON qname
  FOR EACH ROW
  -- Optionally restrict this trigger to fire only when really needed
  WHEN (new.qname_id is null)
DECLARE
  v_id qname.qname_id%TYPE;
BEGIN
  -- Select a new value from the sequence into a local variable. As David
  -- commented, this step is optional. You can directly select into :new.qname_id
  SELECT qname_id_seq.nextval INTO v_id FROM DUAL;

  -- :new references the record that you are about to insert into qname. Hence,
  -- you can overwrite the value of :new.qname_id (qname.qname_id) with the value
  -- obtained from your sequence, before inserting
  :new.qname_id := v_id;
END my_trigger;

In my case, I found that size of Writer have to matched with the frame size both from camera or files. So that I read the frame size first and apply to writer setting as below.

(grabbed, frame) = camera.read()
fshape = frame.shape
fheight = fshape[0]
fwidth = fshape[1]
print fwidth , fheight
fourcc = cv2.VideoWriter_fourcc(*'XVID')
out = cv2.VideoWriter('output.avi',fourcc, 20.0, (fwidth,fheight))

I had the problem due to an extra space in the name of the linked server. "SERVER1, 1234" instead of "SERVER1,1234"

At the moment there are three realy powerfull cmd.exe alternatives:

• cmder
  
• PowerCmd
• ComEmu
• Terminal for Windows 10
  

cmder is an enhancement off ConEmu and Clink

All have features like Copy & Paste, Window Resize per Mouse, Splitscreen, Tabs and a lot of other usefull features.

Using the out keyword with a return type of bool, can sometimes reduce code bloat and increase readability. (Primarily when the extra info in the out param is often ignored.) For instance:

var result = DoThing();
if (result.Success)
{
    result = DoOtherThing()
    if (result.Success)
    {
        result = DoFinalThing()
        if (result.Success)
        {
            success = true;
        }
    }
}

vs:

var result;
if (DoThing(out result))
{
    if (DoOtherThing(out result))
    {
        if (DoFinalThing(out result))
        {
            success = true;
        }
    }
}

android.os.NetworkOnMainThreadException occurs when you try to access network on your main thread (You main activity execution). To avoid this, you must create a separate thread or AsyncTask or Runnable implementation to execute your JSON data loading. Since HoneyComb you can not further execute the network task on main thread. Here is the implementation using AsyncTask for a network task execution
