Quote a word, using single quotes

ciw'Ctrl+r"'

It was easier for me to do it this way

ciw '' Esc P

Additional to putting the variable in quotation, one could also translate the output of the variable using tr and converting spaces to newlines.

$ echo $var | tr " " "\n"
foo
bar
baz

Although this is a little more convoluted, it does add more diversity with the output as you can substitute any character as the separator between array variables.

Both versions are working, either with concatenation by using the escaped single quote character (\'), or with concatenation by enclosing the single quote character within double quotes ("'").

The author of the question did not notice that there was an extra single quote (') at the end of his last escaping attempt:

alias rxvt='urxvt -fg'\''#111111'\'' -bg '\''#111111'\''
           ¦         ¦??|       ¦??¦     ¦??¦       ¦??¦
           +-STRING--+??+-STRIN-+??+-STR-+??+-STRIN-+??¦
                      ??         ??       ??         ??¦
                      ??         ??       ??         ??¦
                      +---------------?---------------+¦
                          All escaped single quotes    ¦
                                                       ¦
                                                       ?

As you can see in the previous nice piece of ASCII/Unicode art, the last escaped single quote (\') is followed by an unnecessary single quote ('). Using a syntax-highlighter like the one present in Notepad++ can prove very helpful.

The same is true for another example like the following one:

alias rc='sed '"'"':a;N;$!ba;s/\n/, /g'"'"
alias rc='sed '\'':a;N;$!ba;s/\n/, /g'\'

These two beautiful instances of aliases show in a very intricate and obfuscated way how a file can be lined down. That is, from a file with a lot of lines you get only one line with commas and spaces between the contents of the previous lines. In order to make sense of the previous comment, the following is an example:

$ cat Little_Commas.TXT
201737194
201802699
201835214

$ rc Little_Commas.TXT
201737194, 201802699, 201835214

Java EE is actually a collection of technologies and APIs for the Java platform designed to support "Enterprise" Applications which can generally be classed as large-scale, distributed, transactional and highly-available applications designed to support mission-critical business requirements.

In terms of what an employee is looking for in specific techs, it is quite hard to say, because the playing field has kept changing over the last five years. It really is about the class of problems that are being solved more than anything else. Transactions and distribution are key.

I think seeing your usage for addEntity and removeEntity code would be helpful, but my first thought is are you actually setting the object.name? Try in your loader just before scene.add(object); something like this:

object.name = "test_name";
scene.add(object);

What might be happening is the default "name" for an Object3D is "", so when you then call your removeEntity function it fails due to the scene objects name being ""

Also, I notice you pass in object.name to your loader? Is this where your storing the URL to the resource? If so, I would recommend using the Object3D's built in .userData method to store that information and keep the name field for scene identification purposes.

Edit: Response to newly added Code

First thing to note is it's not a great idea to have "/" in your object name, it seems to work fine but you never know if some algorithm will decide to escape that string and break your project.

Second item is now that I've seen your code, its actually straight forward whats going on. Your delete function is trying to delete by name, you need an Object3D to delete. Try this:

function removeEntity(object) {
    var selectedObject = scene.getObjectByName(object.name);
    scene.remove( selectedObject );
    animate();
}

Here you see I lookup your Object3D in the Three.js Scene by passing in your object tag's name attribute. Hope that helps

You have two line segments. Define one segment by endpoints A & B and the second segment by endpoints C & D. There is a nice trick to show that they must intersect, WITHIN the bounds of the segments. (Note that the lines themselves may intersect beyond the bounds of the segments, so you must be careful. Good code will also watch for parallel lines.)

The trick is to test that points A and B must line on opposite sides of line CD, AND that points C and D must lie on opposite sides of line AB.

Since this is homework, I won't give you an explicit solution. But a simple test to see which side of a line a point falls on, is to use a dot product. Thus, for a given line CD, compute the normal vector to that line (I'll call it N_C.) Now, simply test the signs of these two results:

dot(A-C,N_C)

and

dot(B-C,N_C)

If those results have opposite signs, then A and B are opposite sides of line CD. Now do the same test for the other line, AB. It has normal vector N_A. Compare the signs of

dot(C-A,N_A)

and

dot(D-A,N_A)

I'll leave it to you to figure out how to compute a normal vector. (In 2-d, that is trivial, but will your code worry about whether A and B are distinct points? Likewise, are C and D distinct?)

You still need to worry about line segments that lie along the same infinite line, or if one point actually falls on the other line segment itself. Good code will cater to every possible problem.

Database table

Having the following blog database table storing the blogs hosted by our platform:

And, we have two blogs currently hosted:

Getting our report without using the SQL LATERAL JOIN

We need to build a report that extracts the following data from the blog table:

• the blog id
• the blog age, in years
• the date for the next blog anniversary
• the number of days remaining until the next anniversary.

If you're using PostgreSQL, then you have to execute the following SQL query:

SELECT
  b.id as blog_id,
  extract(
    YEAR FROM age(now(), b.created_on)
  ) AS age_in_years,
  date(
    created_on + (
      extract(YEAR FROM age(now(), b.created_on)) + 1
    ) * interval '1 year'
  ) AS next_anniversary,
  date(
    created_on + (
      extract(YEAR FROM age(now(), b.created_on)) + 1
    ) * interval '1 year'
  ) - date(now()) AS days_to_next_anniversary
FROM blog b
ORDER BY blog_id

As you can see, the age_in_years has to be defined three times because you need it when calculating the next_anniversary and days_to_next_anniversary values.

And, that's exactly where LATERAL JOIN can help us.

Getting the report using the SQL LATERAL JOIN

The following relational database systems support the LATERAL JOIN syntax:

• Oracle since 12c
• PostgreSQL since 9.3
• MySQL since 8.0.14

SQL Server can emulate the LATERAL JOIN using CROSS APPLY and OUTER APPLY.

LATERAL JOIN allows us to reuse the age_in_years value and just pass it further when calculating the next_anniversary and days_to_next_anniversary values.

The previous query can be rewritten to use the LATERAL JOIN, as follows:

SELECT
  b.id as blog_id,
  age_in_years,
  date(
    created_on + (age_in_years + 1) * interval '1 year'
  ) AS next_anniversary,
  date(
    created_on + (age_in_years + 1) * interval '1 year'
  ) - date(now()) AS days_to_next_anniversary
FROM blog b
CROSS JOIN LATERAL (
  SELECT
    cast(
      extract(YEAR FROM age(now(), b.created_on)) AS int
    ) AS age_in_years
) AS t
ORDER BY blog_id

And, the age_in_years value can be calculated one and reused for the next_anniversary and days_to_next_anniversary computations:

Much better, right?

The age_in_years is calculated for every record of the blog table. So, it works like a correlated subquery, but the subquery records are joined with the primary table and, for this reason, we can reference the columns produced by the subquery.

AlliterativeAlice's example helped me tremendously. In my case, though, the server I was talking to didn't like having single quotes around utf-8 in the content type. It failed with a generic "Server Error" and it took hours to figure out what it didn't like:

request.ContentType = "text/xml; encoding=utf-8";

Another way of doing this, using only JavaScript, would be this:

window.addEventListener('resize', functionName);

This fires every time the size changes, like the other answer.

functionName is the name of the function being executed when the window is resized (the brackets on the end aren't necessary).

Just assign the int to a char variable.

int i = 65;
char c = i;
printf("%c", c); //prints A

This is often caused by the (accidental) removal of the JRE folder that is set in the Eclipse configuration. You can try following these instructions from the Eclipse wiki on how to configure the eclipse.ini file to include the the JRE location, or alternatively, launch eclipse from the command prompt using VM arguments. I have tried them both myself and in my opinion, the command prompt option works much better.

Once you are able to launch Eclipse, make sure you verify the installed JRE location under Java --> Installed JREs in the Preferences window.

In the database, there are two options:

• bytea. Stores the data in a column, exported as part of a backup. Uses standard database functions to save and retrieve. Recommended for your needs.
• blobs. Stores the data externally, not normally exported as part of a backup. Requires special database functions to save and retrieve.

I've used bytea columns with great success in the past storing 10+gb of images with thousands of rows. PG's TOAST functionality pretty much negates any advantage that blobs have. You'll need to include metadata columns in either case for filename, content-type, dimensions, etc.

You don't show us the declaration of carBootSaleList. However from the exception message I can see that it is of type CarBootSaleList. This type doesn't implement the IEnumerable interface and therefore cannot be used in a foreach.

Your CarBootSaleList class should implement IEnumerable<CarBootSale>:

public class CarBootSaleList : IEnumerable<CarBootSale>
{
    private List<CarBootSale> carbootsales;

    ...

    public IEnumerator<CarBootSale> GetEnumerator()
    {
        return carbootsales.GetEnumerator();
    }

    IEnumerator IEnumerable.GetEnumerator()
    {
        return carbootsales.GetEnumerator();
    }
}

Assuming line is a variable which holds your required line number, if you can use head and tail, then it is quite simple:

head -n $line file | tail -1

If not, this should work:

x=0
want=5
cat lines | while read line; do
  x=$(( x+1 ))
  if [ $x -eq "$want" ]; then
    echo $line
    break
  fi
done

In angular, They separate it into 2 kind of url.

1. URL pattern /heroes/:limit. Example: /heroes/20

   • You can get raw value by using route.snapshot.paramMap.get.
   • Subscribe from route.paramMap to get params

2. URL pattern /heroes. Example: /heroes?limit=20

   • You can get raw value by using route.snapshot.queryParamMap

To sum it all up;

function toHex(i, pad) {

  if (typeof(pad) === 'undefined' || pad === null) {
    pad = 2;
  } 

  var strToParse = i.toString(16);

  while (strToParse.length < pad) {
    strToParse = "0" + strToParse;
  }

  var finalVal =  parseInt(strToParse, 16);

  if ( finalVal < 0 ) {
    finalVal = 0xFFFFFFFF + finalVal + 1;
  }

  return finalVal;
}

However, if you don't need to convert it back to an integer at the end (i.e. for colors), then just making sure the values aren't negative should suffice.

With the Dynamic Array formulas(as of this posting only available to Office 365 Insiders):

You might want to check you spaces and tabs. A tab is a default of 4 spaces. However, your "if" and "elif" match, so I am not quite sure why. Go into Options in the top bar, and click "Configure IDLE". Check the Indentation Width on the right in Fonts/Tabs, and make sure your indents have that many spaces.

As answered by Magus :

the full path must me specified

Abstract states can be used to add a prefix to all child state urls. But note that abstract still needs a ui-view for its children to populate. To do so you can simply add it inline.

.state('app', {
   url: "/app",
   abstract: true,
   template: '<ui-view/>'
})

Just an additive.

I know this is old, but I wanted to add a solution I don't see that I came up with myself. Found this question while on hunt of a different solution and just figured, "Well, while I'm here."

First of all, Neal's answer is good and great to use after you run your loop, however, I'd prefer do all work at once. Of course, in my specific case I had to do more work than this simple example here, but the method still applies. I saw where a couple others suggested foreach loops, however, this still leaves you with after work due to the nature of the beast. Normally I suggest simpler things like foreach, however, in this case, it's best to remember good old fashioned for loop logic. Simply use i! To maintain appropriate index, just subtract from i after each removal of an Array item.

Here's my simple, working example:

$array = array(1,2,3,4,5);

for ($i = 0; $i < count($array); $i++) {
    if($array[$i] == 1 || $array[$i] == 2) {
        array_splice($array, $i, 1);
        $i--;
    }
}

Will output:

array(3) {
    [0]=> int(3)
    [1]=> int(4)
    [2]=> int(5)
}

This can have many simple implementations. For example, my exact case required holding of latest item in array based on multidimensional values. I'll show you what I mean:

$files = array(
    array(
        'name' => 'example.zip',
        'size' => '100000000',
        'type' => 'application/x-zip-compressed',
        'url' => '28188b90db990f5c5f75eb960a643b96/example.zip',
        'deleteUrl' => 'server/php/?file=example.zip',
        'deleteType' => 'DELETE'
    ),
    array(
        'name' => 'example.zip',
        'size' => '10726556',
        'type' => 'application/x-zip-compressed',
        'url' => '28188b90db990f5c5f75eb960a643b96/example.zip',
        'deleteUrl' => 'server/php/?file=example.zip',
        'deleteType' => 'DELETE'
    ),
    array(
        'name' => 'example.zip',
        'size' => '110726556',
        'type' => 'application/x-zip-compressed',
        'deleteUrl' => 'server/php/?file=example.zip',
        'deleteType' => 'DELETE'
    ),
    array(
        'name' => 'example2.zip',
        'size' => '12356556',
        'type' => 'application/x-zip-compressed',
        'url' => '28188b90db990f5c5f75eb960a643b96/example2.zip',
        'deleteUrl' => 'server/php/?file=example2.zip',
        'deleteType' => 'DELETE'
    )
);

for ($i = 0; $i < count($files); $i++) {
    if ($i > 0) {
        if (is_array($files[$i-1])) {
            if (!key_exists('name', array_diff($files[$i], $files[$i-1]))) {
                if (!key_exists('url', $files[$i]) && key_exists('url', $files[$i-1])) $files[$i]['url'] = $files[$i-1]['url'];
                $i--;
                array_splice($files, $i, 1);
            }
        }
    }
}

Will output:

array(1) {
    [0]=> array(6) {
            ["name"]=> string(11) "example.zip"
            ["size"]=> string(9) "110726556"
            ["type"]=> string(28) "application/x-zip-compressed"
            ["deleteUrl"]=> string(28) "server/php/?file=example.zip"
            ["deleteType"]=> string(6) "DELETE"
            ["url"]=> string(44) "28188b90db990f5c5f75eb960a643b96/example.zip"
        }
    [1]=> array(6) {
            ["name"]=> string(11) "example2.zip"
            ["size"]=> string(9) "12356556"
            ["type"]=> string(28) "application/x-zip-compressed"
            ["deleteUrl"]=> string(28) "server/php/?file=example2.zip"
            ["deleteType"]=> string(6) "DELETE"
            ["url"]=> string(45) "28188b90db990f5c5f75eb960a643b96/example2.zip"
        }
}

As you see, I manipulate $i before the splice as I'm seeking to remove the previous, rather than the present item.

In shell you assign to a variable without the dollar-sign:

TEST=`pwd`
echo $TEST

that's better (and can be nested) but is not as portable as the backtics:

TEST=$(pwd)
echo $TEST

Always remember: the dollar-sign is only used when reading a variable.

You're looking for the OpenFileDialog class.

For example:

Sub SomeButton_Click(sender As Object, e As EventArgs) Handles SomeButton.Click
    Using dialog As New OpenFileDialog
        If dialog.ShowDialog() <> DialogResult.OK Then Return
        File.Copy(dialog.FileName, newPath)
    End Using
End Sub

If you call your classes tests Maven seems to run them automatically, at least they did for me. Rename the classes and Maven will just go through to verification without running them.

This article suggests the following properties of the browser's navigator object:

• navigator.language (Netscape - Browser Localization)
• navigator.browserLanguage (IE-Specific - Browser Localized Language)
• navigator.systemLanguage (IE-Specific - Windows OS - Localized Language)
• navigator.userLanguage

Roll these into a javascript function and you should be able to guess the right language, in most circumstances. Be sure to degrade gracefully, so have a div containing your language choice links, so that if there is no javascript or the method doesn't work, the user can still decide. If it does work, just hide the div.

The only problem with doing this on the client side is that either you serve up all the languages to the client, or you have to wait until the script has run and detected the language before requesting the right version. Perhaps serving up the most popular language version as a default would irritate the fewest people.

Edit: I'd second Ivan's cookie suggestion, but make sure the user can always change the language later; not everyone prefers the language their browser defaults to.

I find out a possible method by "filter" and "alias" of PowerShell, when you want use grep in pipeline output(grep file should be similar):

first define a filter:

filter Filter-Object ([string]$pattern)
{
    Out-String -InputObject $_ -Stream | Select-String -Pattern "$pattern"
}

then define alias:

New-Alias -Name grep -Value Filter-Object

final, put the former filter and alias in your profile:

$Home[My ]Documents\PowerShell\Microsoft.PowerShell_profile.ps1

Restart your PS, you can use it:

alias | grep 'grep'

For some who wants to reset the form can also use type="reset" inside any form.

<form action="/action_page.php">
Email: <input type="text" name="email"><br>
Pin: <input type="text" name="pin" maxlength="4"><br>
<input type="reset" value="Reset">
<input type="submit" value="Submit">
</form>

use ONLY

function init() { 
    about = document.getElementById("about");
    about.style.color = 'blue';
}

.innerHTML() sets or gets the HTML syntax describing the element's descendants., All you need is an object here.

Demo

Use an SSH key without a passphrase.

Maybe this is obvious to some (wasn't to me). It also doesn't solve the issue if you absolutely require a passphrase, but this was a decent compromise in my situation on Mac.

Use a comma ","

eg: 
UPDATE my_table SET rowOneValue = rowOneValue + 1, rowTwoValue  = rowTwoValue + ( (rowTwoValue / (rowTwoValue) ) + ?) * (v + 1) WHERE value = ?

You can stay DRY and just use node-ipware that supports both IPv4 and IPv6.

Install:

npm install ipware

In your app.js or middleware:

var getIP = require('ipware')().get_ip;
app.use(function(req, res, next) {
    var ipInfo = getIP(req);
    console.log(ipInfo);
    // { clientIp: '127.0.0.1', clientIpRoutable: false }
    next();
});

It will make the best attempt to get the user's IP address or returns 127.0.0.1 to indicate that it could not determine the user's IP address. Take a look at the README file for advanced options.

I've had the same problem.

Use CSS to hide is not the best solution, because sometimes you want users without JS can see the div.. The cleanest solution is to hide the div with JQuery. But the div is visible about 0.5 seconde, which is problematic if the div is on the top of the page.

In these cases, I use an intermediate solution, without JQuery. This one works and is immediate :

<script>document.write('<style>.js_hidden { display: none; }</style>');</script>

<div class="js_hidden">This div will be hidden for JS users, and visible for non JS users.</div>

Of course, you can still add all the effects you want on the div, JQuery toggle() for example. And you will get the best behaviour possible (imho) :

• for non JS users, the div is visible directly
• for JS users, the div is hidden and has toggle effect.

        System.out.println("DB Connection started");
        Statement sta = conn.createStatement();
        String Sql = "select * from TABLE_NAME";
        ResultSet rs = sta.executeQuery(Sql);
        while (rs.next()) {
            System.out.println(rs.getString("COLUMN_NAME"));
        }
    }

anyway you have not a unlimited accuracy so C define a constant in this way:

#define PI 3.14159265358979323846

import math.h to use this

Just as an addition to the accepted answer, you might find your code looking more consistent when using the LINQ method syntax:

Context.person_account_portfolio
.Where(p => person_id == personId)
.ToList()
.ForEach(x => x.is_default = false);

.ToList() is neccessary because .ForEach() is defined only on List<T>, not on IEnumerable<T>. Just be aware .ToList() is going to execute the query and load ALL matching rows from database before executing the loop.

Years later, but a useful option would be to utilize XPath Axes (https://www.w3schools.com/xml/xpath_axes.asp). More specifically, you are looking to use the descendants axes.

I believe this example would do the trick:

//book[descendant::title[@lang='it']]

This allows you to select all book elements that contain a child title element (regardless of how deep it is nested) containing language attribute value equal to 'it'.

I cannot say for sure whether or not this answer is relevant to the year 2009 as I am not 100% certain that the XPath Axes existed at that time. What I can confirm is that they do exist today and I have found them to be extremely useful in XPath navigation and I am sure you will as well.

An alternative solution is described on Separate sentence to one word per line, by applying display:table-caption; to the element

This way you can create Observable from data, in my case I need to maintain shopping cart:

service.ts

export class OrderService {
    cartItems: BehaviorSubject<Array<any>> = new BehaviorSubject([]);
    cartItems$ = this.cartItems.asObservable();

    // I need to maintain cart, so add items in cart

    addCartData(data) {
        const currentValue = this.cartItems.value; // get current items in cart
        const updatedValue = [...currentValue, data]; // push new item in cart

        if(updatedValue.length) {
          this.cartItems.next(updatedValue); // notify to all subscribers
        }
      }
}

Component.ts

export class CartViewComponent implements OnInit {
    cartProductList: any = [];
    constructor(
        private order: OrderService
    ) { }

    ngOnInit() {
        this.order.cartItems$.subscribe(items => {
            this.cartProductList = items;
        });
    }
}

A couple of plain old foreach loops provides a clean solution:

foreach (XElement level1Element in XElement.Load("data.xml").Elements("level1"))
{
    result.AppendLine(level1Element.Attribute("name").Value);

    foreach (XElement level2Element in level1Element.Elements("level2"))
    {
        result.AppendLine("  " + level2Element.Attribute("name").Value);
    }
}

^dbo\..*_fn$

This should work you.

I got this error when running a query without SSL.

Simply changing the URL scheme of my request from HTTP to HTTPS fixed it.

You can use SUBSTRING(locations.raw,-6,4) for where conditon

SELECT `users`.`first_name`, `users`.`last_name`, `users`.`email`,
SUBSTRING(`locations`.`raw`,-6,4) AS `guaranteed_postcode`
FROM `users` LEFT OUTER JOIN `locations`
ON `users`.`id` = `locations`.`user_id`
WHERE SUBSTRING(`locations`.`raw`,-6,4) NOT IN #this is where the fake col is being used
(
SELECT `postcode` FROM `postcodes` WHERE `region` IN
(
 'australia'
)
)

private void dataGridView1_CellClick(object sender, DataGridViewCellEventArgs e)
{
    if (dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex].Value != null)
    {
       MessageBox.Show(dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex].Value.ToString());
    }
}

os.path.basename(os.path.normpath('/folderA/folderB/folderC/folderD/'))

Try this :) don't know if it works.

Make sure your article:author data is a Facebook author URL. Unfortunately, that conflicts with what Pinterest is expecting. It's the best thing about standards, there are so many ways to implement them!

<meta property="article:author" content="https://www.facebook.com/mpatnode76">

But Pinterest wants to see something like this:

<meta property="article:author" content="Mike Patnode">

We ended up swapping the formats depending upon the user agent. Hopefully, that doesn't screw up your page cache. That fixed it for us.

Full disclosure. Found this here: https://surniaulula.com/2014/03/01/pinterest-articleauthor-incompatible-with-open-graph/

Editing Dialogs

One good ability to edit dialogs is using SharpDevelop in a version 4.0.1.7090 (or higher). With help of this tool a standalone dialog (wxs files from WiX sources like e.g. InstallDirDlg.wxs) can be opened, previewed and edited in Design view.

In Google Sheets you can use =ArrayFormula(Sheet1!B2:B)on the first cell and it will populate all column contents not sure if that will work in excel

The command is date

To customise the output there are a myriad of options available, see date --help for a list.

For example, date '+%A %W %Y %X' gives Tuesday 34 2013 08:04:22 which is the name of the day of the week, the week number, the year and the time.

You're trying to concatenate a string and an integer, which is incorrect.

Change print(numlist.pop(2)+" has been removed") to any of these:

Explicit int to str conversion:

print(str(numlist.pop(2)) + " has been removed")

Use , instead of +:

print(numlist.pop(2), "has been removed")

String formatting:

print("{} has been removed".format(numlist.pop(2)))

Mike Nereson has this to say on his blog at:

http://blog.codehangover.com/load-multiple-contexts-into-spring/

There are a couple of ways to do this.

1. web.xml contextConfigLocation

Your first option is to load them all into your Web application context via the ContextConfigLocation element. You’re already going to have your primary applicationContext here, assuming you’re writing a web application. All you need to do is put some white space between the declaration of the next context.

  <context-param>
      <param-name> contextConfigLocation </param-name>
      <param-value>
          applicationContext1.xml
          applicationContext2.xml
      </param-value>
  </context-param>

  <listener>
      <listener-class>
          org.springframework.web.context.ContextLoaderListener
      </listener-class>
  </listener>

The above uses carriage returns. Alternatively, yo could just put in a space.

  <context-param>
      <param-name> contextConfigLocation </param-name>
      <param-value> applicationContext1.xml applicationContext2.xml </param-value>
  </context-param>

  <listener>
      <listener-class> org.springframework.web.context.ContextLoaderListener </listener-class>
  </listener>

2. applicationContext.xml import resource

Your other option is to just add your primary applicationContext.xml to the web.xml and then use import statements in that primary context.

In applicationContext.xml you might have…

  <!-- hibernate configuration and mappings -->
  <import resource="applicationContext-hibernate.xml"/>

  <!-- ldap -->
  <import resource="applicationContext-ldap.xml"/>

  <!-- aspects -->
  <import resource="applicationContext-aspects.xml"/>

Which strategy should you use?

1. I always prefer to load up via web.xml.

Because , this allows me to keep all contexts isolated from each other. With tests, we can load just the contexts that we need to run those tests. This makes development more modular too as components stay loosely coupled, so that in the future I can extract a package or vertical layer and move it to its own module.

2. If you are loading contexts into a non-web application, I would use the import resource.

Use the SC command, like this (you need to be on a command prompt to execute the commands in this post):

SC STOP shortservicename
SC DELETE shortservicename

Note: You need to run the command prompt as an administrator, not just logged in as the administrator, but also with administrative rights. If you get errors above about not having the necessary access rights to stop and/or delete the service, run the command prompt as an administrator. You can do this by searching for the command prompt on your start menu and then right-clicking and selecting "Run as administrator". Note to PowerShell users: sc is aliased to set-content. So sc delete service will actually create a file called delete with the content service. To do this in Powershell, use sc.exe delete service instead

If you need to find the short service name of a service, use the following command to generate a text file containing a list of services and their statuses:

SC QUERY state= all >"C:\Service List.txt"

For a more concise list, execute this command:

SC QUERY state= all | FIND "_NAME"

The short service name will be listed just above the display name, like this:

SERVICE_NAME: MyService
DISPLAY_NAME: My Special Service

And thus to delete that service:

SC STOP MyService
SC DELETE MyService

this is Postgres UPDATE JOIN format:

UPDATE address 
SET cid = customers.id
FROM customers 
WHERE customers.id = address.id

Here's the other variations: http://mssql-to-postgresql.blogspot.com/2007/12/updates-in-postgresql-ms-sql-mysql.html

Introduction

Object-Relational Mapping (ORM) is a technique that lets you query and manipulate data from a database using an object-oriented paradigm. When talking about ORM, most people are referring to a library that implements the Object-Relational Mapping technique, hence the phrase "an ORM".

An ORM library is a completely ordinary library written in your language of choice that encapsulates the code needed to manipulate the data, so you don't use SQL anymore; you interact directly with an object in the same language you're using.

For example, here is a completely imaginary case with a pseudo language:

You have a book class, you want to retrieve all the books of which the author is "Linus". Manually, you would do something like that:

book_list = new List();
sql = "SELECT book FROM library WHERE author = 'Linus'";
data = query(sql); // I over simplify ...
while (row = data.next())
{
     book = new Book();
     book.setAuthor(row.get('author');
     book_list.add(book);
}

With an ORM library, it would look like this:

book_list = BookTable.query(author="Linus");

The mechanical part is taken care of automatically via the ORM library.

Pros and Cons

Using ORM saves a lot of time because:

• DRY: You write your data model in only one place, and it's easier to update, maintain, and reuse the code.
• A lot of stuff is done automatically, from database handling to I18N.
• It forces you to write MVC code, which, in the end, makes your code a little cleaner.
• You don't have to write poorly-formed SQL (most Web programmers really suck at it, because SQL is treated like a "sub" language, when in reality it's a very powerful and complex one).
• Sanitizing; using prepared statements or transactions are as easy as calling a method.

Using an ORM library is more flexible because:

• It fits in your natural way of coding (it's your language!).
• It abstracts the DB system, so you can change it whenever you want.
• The model is weakly bound to the rest of the application, so you can change it or use it anywhere else.
• It lets you use OOP goodness like data inheritance without a headache.

But ORM can be a pain:

• You have to learn it, and ORM libraries are not lightweight tools;
• You have to set it up. Same problem.
• Performance is OK for usual queries, but a SQL master will always do better with his own SQL for big projects.
• It abstracts the DB. While it's OK if you know what's happening behind the scene, it's a trap for new programmers that can write very greedy statements, like a heavy hit in a for loop.

How to learn about ORM?

Well, use one. Whichever ORM library you choose, they all use the same principles. There are a lot of ORM libraries around here:

• Java: Hibernate.
• PHP: Propel or Doctrine (I prefer the last one).
• Python: the Django ORM or SQLAlchemy (My favorite ORM library ever).
• C#: NHibernate or Entity Framework

If you want to try an ORM library in Web programming, you'd be better off using an entire framework stack like:

• Symfony (PHP, using Propel or Doctrine).
• Django (Python, using a internal ORM).

Do not try to write your own ORM, unless you are trying to learn something. This is a gigantic piece of work, and the old ones took a lot of time and work before they became reliable.

Today I filed a JEP draft to OpenJDK about this aliasing feature. I hope they will reconsider it.

If you are interested, you can find a JEP draft here: https://gist.github.com/cardil/b29a81efd64a09585076fe00e3d34de7

HTML Code:-

<input type="text" name="txt1" id="txt1" onkeypress="return AddKeyPress(event);" />      

<input type="button" id="btnclick">

Java Script Code

function AddKeyPress(e) { 
        // look for window.event in case event isn't passed in
        e = e || window.event;
        if (e.keyCode == 13) {
            document.getElementById('btnEmail').click();
            return false;
        }
        return true;
    }

Your Form do not have Default Submit Button

I use tortoiseGit. I had the same problem. Then in push settings I unchecked "autoload putty key", tried to push, then I checked it again, and pushed, and it worked. But seriously, I don't know why.

As of OSX 10.10 (Yosemite) and since at least OS X 10.8 (Mountain Lion), the behavior is as follows when you open (double-click) executable scripts from Finder:

• Executable scripts^[1] with either NO suffix or suffix .command:
• are executed by default - no setup required:
  • a new Terminal window opens in which the script runs.
  • by default, the window will remain open after the script terminates so you can inspect the output (though at that point the shell that ran the script has exited and you cannot interact with it any longer).
    However, via Terminal's Preferences... > Profiles you can opt to automatically close the window when the script exits.
• Caveat: the working folder is invariably the current user's home folder, NOT the folder in which the script is located.
  • To make a shell script change to the folder in which it is located, place
    • cd -- "$(dirname "$BASH_SOURCE")" right after the shebang line
    • or, if you must remain POSIX-compliant, cd -- "$(dirname "$0")".
    • For edge cases, such as finding a symlinked script's true source directory, see this answer.
• If the script is unexpectedly not executable:
  • Make it executable by running chmod +x <script> in Terminal; otherwise, you'll see the following symptoms:
  • .command: Finder displays a misleading error message that suggests the problem can be fixed via File > Get Info, which is not true - use the chmod +x method suggested above.
  • no suffix:
    • with a shebang line (e.g., #!/bin/bash): behavior is as if the suffix were .sh - see below.
    • with no shebang line: opens in your default text editor (which is TextEdit by default).
• Scripts with suffix .sh, whether executable or not:
• are opened for editing in TextEdit.app or, if installed, with Xcode.app.
• Scripts with suffix .scpt or .applescript (even if they're themselves marked as executable, which is not normally the case):
  • opened for editing in [Apple]Script Editor
  • Note that the JXA source-code files seem to have no distinct suffix (yet).
• Scripts with a custom suffix (a suffix not yet known to the system), whether executable or not (in fact, applies to any kind of file):
  • prompt you for the app to open them with when you first open them, and remember that choice.

^{[1] Executable means: a script with the executable permission bit(s) set and the calling user - relative to the ownership to the file - therefore potentially being allowed to execute it.
If you use chmod a+x to set all permission bits (which is typical), anyone can invoke it (assuming they're also allowed to read the file based on the read permission bit(s) and the file's ownership).}

JavaScript:

function maketimus(timestampz)
{
    var linktime = new Date(timestampz * 1000);
    var linkday = linktime.getDate();
    var freakingmonths = new Array();

    freakingmonths[0]  = "jan";
    freakingmonths[1]  = "feb";
    freakingmonths[2]  = "mar";
    freakingmonths[3]  = "apr";
    freakingmonths[4]  = "may";
    freakingmonths[5]  = "jun";
    freakingmonths[6]  = "jul";
    freakingmonths[7]  = "aug";
    freakingmonths[8]  = "sep";
    freakingmonths[9]  = "oct";
    freakingmonths[10] = "nov";
    freakingmonths[11] = "dec";

    var linkmonthnum = linktime.getMonth();
    var linkmonth = freakingmonths[linkmonthnum];
    var linkyear = linktime.getFullYear();
    var linkhour = linktime.getHours();
    var linkminute = linktime.getMinutes();

    if (linkminute < 10)
    {
        linkminute = "0" + linkminute;
    }

    var fomratedtime = linkday + linkmonth + linkyear + " " +
                       linkhour + ":" + linkminute + "h";
    return fomratedtime;
}

Simply provide your times in Unix timestamp format to this function; JavaScript already knows the timezone of the user.

Like this:

PHP:

echo '<script type="text/javascript">
var eltimio = maketimus('.$unix_timestamp_ofshiz.');
document.write(eltimio);
</script><noscript>pls enable javascript</noscript>';

This will always show the times correctly based on the timezone the person has set on his/her computer clock. There is no need to ask anything to anyone and save it into places, thank god!

public static class DateTimeExtensions
{
    public static DateTime LastDayOfMonth(this DateTime date)
    {
        return date.AddDays(1-(date.Day)).AddMonths(1).AddDays(-1);
    }
}

From what I understand, you have your data on a table and you want to create the CSV from that data. However, you have problem creating the CSV.

My thoughts would be to iterate and parse the contents of the table and generate a string from the parsed data. You can check How to convert JSON to CSV format and store in a variable for an example. You are using jQuery in your example so that would not count as an external plugin. Then, you just have to serve the resulting string using window.open and use application/octetstream as suggested.

Something like this in your form main. Double click the form in the visual editor to create the form load event.

 Timer Clock=new Timer();
 Clock.Interval=2700000; // not sure if this length of time will work 
 Clock.Start();
 Clock.Tick+=new EventHandler(Timer_Tick);

Then add an event handler to do something when the timer fires.

  public void Timer_Tick(object sender,EventArgs eArgs)
  {
    if(sender==Clock)
    {
      // do something here      
    }
  }

You can use Oracle.ManagedDataAccess.dll instead (download from Oracle), include that dll in you project bin dir, add reference to that dll in the project. In code, "using Oracle.MangedDataAccess.Client". Deploy project to server as usual. No need install Oracle Client on server. No need to add assembly info in web.config.

To directly answer your question if you want to return a view that belongs to another controller you simply have to specify the name of the view and its folder name.

public class CommentsController : Controller
{
    public ActionResult Index()
    { 
        return View("../Articles/Index", model );
    }
}

and

public class ArticlesController : Controller
{
    public ActionResult Index()
    { 
        return View();
    }
}

Also, you're talking about using a read and write method from one controller in another. I think you should directly access those methods through a model rather than calling into another controller as the other controller probably returns html.

I have written this article about the ICommand interface.

The idea - creating a universal command that takes two delegates: one is called when ICommand.Execute (object param) is invoked, the second checks the status of whether you can execute the command (ICommand.CanExecute (object param)).

Requires the method to switching event CanExecuteChanged. It is called from the user interface elements for switching the state CanExecute() command.

public class ModelCommand : ICommand
{
    #region Constructors

    public ModelCommand(Action<object> execute)
        : this(execute, null) { }

    public ModelCommand(Action<object> execute, Predicate<object> canExecute)
    {
        _execute = execute;
        _canExecute = canExecute;
    }

    #endregion

    #region ICommand Members

    public event EventHandler CanExecuteChanged;

    public bool CanExecute(object parameter)
    {
        return _canExecute != null ? _canExecute(parameter) : true;
    }

    public void Execute(object parameter)
    {
        if (_execute != null)
            _execute(parameter);
    }

    public void OnCanExecuteChanged()
    {
        CanExecuteChanged(this, EventArgs.Empty);
    }

    #endregion

    private readonly Action<object> _execute = null;
    private readonly Predicate<object> _canExecute = null;
}

It's possible your Java compiler is configured not to preserve variable information. Right-click on the project in Project Explorer, then select Properties > Java Compiler > Add variable attributes to generated class files (used by the debugger). Without this option set, you will only see fields in the Variables view, not local variables.

if you want to stay DRY, use an include.

{% if foo %}
  {% with a as b %}
    {% include "snipet.html" %}
  {% endwith %} 
{% else %}
  {% with bar as b %}
    {% include "snipet.html" %}
  {% endwith %} 
{% endif %}

or, even better would be to write a method on the model that encapsulates the core logic:

def Patient(models.Model):
    ....
    def get_legally_responsible_party(self):
       if self.age > 18:
          return self
       else:
          return self.parent

Then in the template:

{% with patient.get_legally_responsible_party as p %}
  Do html stuff
{% endwith %} 

Then in the future, if the logic for who is legally responsible changes you have a single place to change the logic -- far more DRY than having to change if statements in a dozen templates.

All the above answers really help me to construct my answer, because of this I voted for all the answers that other users put it out: But I finally put together my own answer to exact problem I was dealing with:

As question clearly defined I had to access some of the siblings and its children in a dom structure: This solution will iterate over the images in the dom structure and construct image name using product title and save the image to the local directory.

• Select MY_FOLDER >> Add MY_FILE.Swift
• Voila ! You are good to go .

Chrome developer tools allows to see handshake request which stays pending during the opened connection, but you can't see traffic as far as I know. However you can sniff it for example.

You can consider to replace default WordPress jQuery script with Google Library by adding something like the following into theme functions.php file:

function modify_jquery() {
    if (!is_admin()) {
        wp_deregister_script('jquery');
        wp_register_script('jquery', 'http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js', false, '1.10.2');
        wp_enqueue_script('jquery');
    }
}
add_action('init', 'modify_jquery');

<?php

$string = "<element><child>Hello World</child></element>";
$xml = new SimpleXMLElement($string);

$text = (string)$xml->child;

$text will be 'Hello World'

Everything is mirrored on omapzoom.org. Some of the code is also mirrored on github.

Contacts is here for example.

Since December 2019, you can use the new official public code search tool for AOSP: cs.android.com. There's also the Android official source browser (based on Gitiles) has a web view of many of the different parts that make up android. Some of the projects (such as Kernel) have been removed and it now only points you to clonable git repositories.

To get all the code locally, you can use the repo helper program, or you can just clone individual repositories.

And others:

• Downloading the Source Tree

This a variant of brettdj's & pstraton post.

This will return a true Value and not give you the #NUM! error. And \D is shorthand for anything but digits. The rest is much like the others only with this minor fix.

Function StripChar(Txt As String) As Variant
With CreateObject("VBScript.RegExp")
    .Global = True
    .Pattern = "\D"
    StripChar = Val(.Replace(Txt, " "))
End With
End Function

I suggest you truncate first, and then format:

double a = 123.4567;
double aTruncated = Math.Truncate(a * 100) / 100;
CultureInfo ci = new CultureInfo("de-DE");
string s = string.Format(ci, "{0:0.00}%", aTruncated);

Use the constant 100 for 2 digits truncate; use a 1 followed by as many zeros as digits after the decimal point you would like. Use the culture name you need to adjust the formatting result.

how about in vuejs how is it applicable?

From Anko library method

fun Context.browse(url: String, newTask: Boolean = false): Boolean {
    try {
        val intent = Intent(Intent.ACTION_VIEW)
        intent.data = Uri.parse(url)
        if (newTask) {
            intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK)
        }
        startActivity(intent)
        return true
    } catch (e: ActivityNotFoundException) {
        e.printStackTrace()
        return false
    }
}

In your NGINX vhost file, in location block which processes your PHP files (usually location ~ \.php$ {) through FastCGI, make sure you have next lines:

proxy_buffer_size          128k;
proxy_buffers              4 256k;
proxy_busy_buffers_size    256k;
fastcgi_buffer_size        16k;
fastcgi_buffers            4 16k;

After that don't forget to restart fpm and nginx.

Additional:

NGINX vhost paths

• /etc/nginx/sites-enabled/ - Linux
• '/usr/local/etc/nginx/sites-enabled/' - Mac

Restart NGINX:

• sudo service nginx restart - Linux
• brew service restart nginx - Mac

Restart FPM:

Determine fpm process name: - systemctl list-unit-files | grep fpm - Linux - brew services list | grep php - Mac

and then restart it with:

• sudo service <service-name> restart - Linux
• brew services restart <service-name> - Mac

To get the value of the Value attribute you can do something like this:

$("input[type='checkbox']").val();

Or if you have set a class or id for it, you can:

$('#check_id').val();
$('.check_class').val();

However this will return the same value whether it is checked or not, this can be confusing as it is different to the submitted form behaviour.

To check whether it is checked or not, do:

if ($('#check_id').is(":checked"))
{
  // it is checked
}

DISCLAMER: Following code creates different threads for each function.

This might be useful for some of the cases as it is simpler to use. But know that it is not async but gives illusion of async using multiple threads, even though decorator suggests that.

To make any function non blocking, simply copy the decorator and decorate any function with a callback function as parameter. The callback function will receive the data returned from the function.

import asyncio
import requests


def run_async(callback):
    def inner(func):
        def wrapper(*args, **kwargs):
            def __exec():
                out = func(*args, **kwargs)
                callback(out)
                return out

            return asyncio.get_event_loop().run_in_executor(None, __exec)

        return wrapper

    return inner


def _callback(*args):
    print(args)


# Must provide a callback function, callback func will be executed after the func completes execution !!
@run_async(_callback)
def get(url):
    return requests.get(url)


get("https://google.com")
print("Non blocking code ran !!")

I also just changed the "Start in" setting of the shortcut icon to: %HOMEDRIVE%/xampp/htdocs/

go_as's answer as a one liner

 python -c "help('modules');" | grep module

So , just make sure that you are on the right environment i.e 32 bit SWT LIBRARIES should match 32 bit JVM , vice versa.

I solved this problem by installing 64-bit jdk ,64-bit jre and finally by adding setting the jdk path in environment variables adn adding jre to the eclipse.

alter table [table name] remove [present column name] to [new column name.

I created a JsFiddle here based on the answer given by Zachary. It provides a more accessible user interface and also escapes double quotes within strings properly.

The accepted answer is correct but I will rewrite complete steps for java.

I am currently using Swagger V2 with Spring Boot 2 and it's straightforward 3 step process.

Step 1: Add required dependencies in pom.xml file. The second dependency is optional use it only if you need Swagger UI.

        <!-- https://mvnrepository.com/artifact/io.springfox/springfox-swagger2 -->
        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger2</artifactId>
            <version>2.9.2</version>
        </dependency>
        <!-- https://mvnrepository.com/artifact/io.springfox/springfox-swagger-ui -->
        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger-ui</artifactId>
            <version>2.9.2</version>
        </dependency>

Step 2: Add configuration class

@Configuration
@EnableSwagger2
public class SwaggerConfig {

     public static final Contact DEFAULT_CONTACT = new Contact("Usama Amjad", "https://stackoverflow.com/users/4704510/usamaamjad", "[email protected]");
      public static final ApiInfo DEFAULT_API_INFO = new ApiInfo("Article API", "Article API documentation sample", "1.0", "urn:tos",
              DEFAULT_CONTACT, "Apache 2.0", "http://www.apache.org/licenses/LICENSE-2.0", new ArrayList<VendorExtension>());

    @Bean
    public Docket api() {
        Set<String> producesAndConsumes = new HashSet<>();
        producesAndConsumes.add("application/json");
        return new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(DEFAULT_API_INFO)
                .produces(producesAndConsumes)
                .consumes(producesAndConsumes);

    }
}

Step 3: Setup complete and now you need to document APIs in controllers

    @ApiOperation(value = "Returns a list Articles for a given Author", response = Article.class, responseContainer = "List")
    @ApiResponses(value = { @ApiResponse(code = 200, message = "Success"),
            @ApiResponse(code = 404, message = "The resource you were trying to reach is not found") })
    @GetMapping(path = "/articles/users/{userId}")
    public List<Article> getArticlesByUser() {
       // Do your code
    }

Usage:

You can access your Documentation from http://localhost:8080/v2/api-docs just copy it and paste in Postman to import collection.

Optional Swagger UI: You can also use standalone UI without any other rest client via http://localhost:8080/swagger-ui.html and it's pretty good, you can host your documentation without any hassle.

Try to use this with single quotes in data:

insert into table test_hive values ('1','puneet');

Expanding on Brian Camire's Answer:

Using =MEDIAN(IF($A$1:$A$6="Airline",$B$1:$B$6,"")) with CTRL+SHIFT+ENTER will include blank cells in the calculation. Blank cells will be evaluated as 0 which results in a lower median value. The same is true if using the average funtion. If you don't want to include blank cells in the calculation, use a nested if statement like so:

=MEDIAN(IF($A$1:$A$6="Airline",IF($B$1:$B$6<>"",$B$1:$B$6)))

Don't forget to press CTRL+SHIFT+ENTER to treat the formula as an "array formula".

Huffman encoding is a sensible option here. Gzip and friends do this, but the way they work is to build a Huffman tree for the input, send that, then send the data encoded with the tree. If the tree is large relative to the data, there may be no not saving in size.

However, it is possible to avoid sending a tree: instead, you arrange for the sender and receiver to already have one. It can't be built specifically for every string, but you can have a single global tree used to encode all strings. If you build it from the same language as the input strings (English or whatever), you should still get good compression, although not as good as with a custom tree for every input.

I was looking for a solution to the opposite problem where I needed a fixed width div in the centre and a fluid width div on either side, so I came up with the following and thought I'd post it here in case anyone needs it.

#wrapper {_x000D_
  clear: both;_x000D_
  width: 100%;_x000D_
}_x000D_
_x000D_
#wrapper div {_x000D_
  display: inline-block;_x000D_
  height: 500px;_x000D_
}_x000D_
_x000D_
#center {_x000D_
  background-color: green;_x000D_
  margin: 0 auto;_x000D_
  overflow: auto;_x000D_
  width: 500px;_x000D_
}_x000D_
_x000D_
#left {_x000D_
  float: left;_x000D_
}_x000D_
_x000D_
#right {_x000D_
  float: right;_x000D_
}_x000D_
_x000D_
.fluid {_x000D_
  background-color: yellow;_x000D_
  width: calc(50% - 250px);_x000D_
}

<div id="wrapper">_x000D_
  <div id="center">_x000D_
    This is fixed width in the centre_x000D_
  </div>_x000D_
  <div id="left" class="fluid">_x000D_
    This is fluid width on the left_x000D_
  </div>_x000D_
  <div id="right" class="fluid">_x000D_
    This is fluid width on the right_x000D_
  </div>_x000D_
</div>

If you change the width of the #center element then you need to update the width property of .fluid to:

width: calc(50% - [half of center width]px);

Try Color class method:

public static int parseColor (String colorString)

From Android documentation:

Supported formats are: #RRGGBB #AARRGGBB 'red', 'blue', 'green', 'black', 'white', 'gray', 'cyan', 'magenta', 'yellow', 'lightgray', 'darkgray'

AndroidX: String.toColorInt()

Fastest way I think

       $newArray = array();

for($count == 0;$row = mysql_fetch_assoc($getResults);$count++)
    {
    foreach($row as $key => $value)
    { 
    $newArray[$count]{$key} = $row[$key];
    }
}

I could reproduce this issue by creating an enumeration with a non-static member class and a static block enumerating its values:

public enum Foo {
Dummy(new Bar [] {new Bar()});
static {
    for (Foo foo: Foo.values());
}
private Foo(Bar [] params) {}
public class Bar {}
 }

This class breaks the Ganymede compiler. If you delete the line in the static initializer block, the code compiles correctly again, and you get the error that there is no enclosing instance for the new Bar() call, as expected.

-- correction: The above holds only if the project has gaeNature from Google Appengine. However, if you get an error similar as mentioned in the original question, you might be encountering another java compiler bug ...

Use:

int Years(DateTime start, DateTime end)
{
    return (end.Year - start.Year - 1) +
        (((end.Month > start.Month) ||
        ((end.Month == start.Month) && (end.Day >= start.Day))) ? 1 : 0);
}

If you have a clean (un-modified) working copy

To rollback one commit (make sure you note the commit's hash for the next step):

git reset --hard HEAD^

To pull that commit into a different branch:

git checkout other-branch
git cherry-pick COMMIT-HASH

If you have modified or untracked changes

Also note that git reset --hard will kill any untracked and modified changes you might have, so if you have those you might prefer:

git reset HEAD^
git checkout .

There is no way to do that as the author of the HTML that a browser renders. At least not yet that I know of. Its pretty much up to the browser and its settings / preferences that are set by users themselves.

Also, you shouldn't impose this upon any user. A browser is the user's property. If a user wants to open all links in tabs or in new windows, then let the user do exactly that.

It's good that we can't do certain things. target=_blank is still abused and popups have been done to death.

Maybe you should just write the ImageView first and the TextView second. That can help sometimes. That's simple but I hope it helps somebody. :)

1. CTRL + comma
2. Search for indent using tabs
3. Go and change Editor: Tab Size

That's aLL

If you'd like to explicitly declare your package dependencies or automate the download, you can add a node package to pull in google fonts and serve locally.

npm - Google Font Downloads

The typefaces project creates NPM packages for Open Source typefaces :

Each package ships with all the necessary fons and css to self-host an open source typeface.
All Google Fonts have been added as well as a small but growing list of other open source fonts.

Just search npm for typeface-<typefacename> to browse the available fonts like typeface-roboto or typeface-open-sans and install like this:

$ npm install typeface-roboto    --save 
$ npm install typeface-open-sans --save 
$ npm install material-icons     --save 

npm - Google Fonts Download-ers

For the more generic use case, there are several npm packages that will deliver fonts in two steps, first by obtaining the package, and then by pointing it to the font name and options you'd like to include.

Here are some of the options:

• Google Fonts Webpack Plugin
• Google Fonts Offline
• Google Fonts
• Get Google Fonts

I've done what you suggest, and I don't see a "Renew" button either.

The following is how I got mine renewed.

I see my three profiles (companynameProfile, "Team Provisioning Profile", and productnameProfile). THe first and third are going to expire within a couple of weeks. The second (and only the second) is flagged as "managed by Xcode". The profile names appear in a table with columns labelled: "Provisioning Profile", App ID, Status, and Actions. The status for all three is "Active". First 1 and 3, the Actions column has a "Download" button, and an "Edit" link. For 2, gthe Actions column has only the "Download" button.

There is no "Renew" (or "Refresh") button / link anywhere (and I did a view-source and searched that too :)

So, I thought...click on "Edit" on #3 ... two choices pop-up: Modify and Duplicate. I chose "Modify"

There is still no renew/refresh ... but there is a "Submit" button ... which doesn't work (turns out its sort of grayed out, but that's not at all obvious...bad UI design).

I discovered that if I change something on the screen (in my case, I selected a previously unused device), "Submit" darkens (becomes available). Click on "Submit". You're quietly (another UI problem :) taken back to the prior page, and the "Download" and "Edit" buttons are gone, and the status column should say "Pending"!

After awhile, I refreshed the window (reloaded) (don't know if it would have auto-refreshed) ... and saw that the status column had changed to "Active".

Now...I downloaded the new profile (the one that the darn page doesn't tell you is new, and doesn't LIST THE EXPIRATION DATE so you could tell yourself ... third UI flaw already :)

I downloaded the profile, deleted the old profile from the list in the Organizer window of Xcode, then dragged the new one into the Organizer window of Xcode, and ... voila, Organizer shows a new expiration date (of about 3 months from today).

Hope that helps,

array_push — Push one or more elements onto the end of array

Take note of the words "one or more elements onto the end" to do that using $arr[] you would have to get the max size of the array

Try this:

function funcName() {
    alert("test");
}

var run = setInterval(funcName, 10000)

Step 1: Add new column with integer or numeric as per your requirement

Step 2: Populate data from varchar column to numeric column

Step 3: drop varchar column

Step 4: change new numeric column name as per old varchar column

Using Socket.IO 1.x:

Get array of the connected clients:

io.engine === io.eio // => true
Object.keys(io.engine.clients) // => [ 'US8AxrUrrDF_G7ZUAAAA', 'Ov2Ca24Olkhf2NHbAAAB' ]
Object.keys(io.eio.clients)    // => [ 'US8AxrUrrDF_G7ZUAAAA', 'Ov2Ca24Olkhf2NHbAAAB' ]

Get the number of connected clients:

io.engine.clientsCount // => 2
io.eio.clientsCount    // => 2

Add a Console.ReadKey call to your program to force it to wait for you to press a key before exiting.

I had this same problem. Go into a python shell and type:

>>> import nltk
>>> nltk.download()

Then an installation window appears. Go to the 'Models' tab and select 'punkt' from under the 'Identifier' column. Then click Download and it will install the necessary files. Then it should work!

Basically, don't use ArrayList.toString() - build the string up for yourself. For example:

StringBuilder builder = new StringBuilder();
for (String value : publicArray) {
    builder.append(value);
}
String text = builder.toString();

(Personally I wouldn't call the variable publicArray when it's not actually an array, by the way.)

You can use checkout or co

$ svn co http://example.com/svn/app-name directory-name

Some short codes:-

1. checkout (co)
2. commit (ci)
3. copy (cp)
4. delete (del, remove,rm)
5. diff (di)

I had a similar issue uploading to an S3 bucket protected with KWS encryption. I have a minimal policy that allows the addition of objects under a specific s3 key.

I needed to add the following KMS permissions to my policy to allow the role to put objects in the bucket. (Might be slightly more than are strictly required)

What the error is telling, is that you can't convert an entire list into an integer. You could get an index from the list and convert that into an integer:

x = ["0", "1", "2"] 
y = int(x[0]) #accessing the zeroth element

If you're trying to convert a whole list into an integer, you are going to have to convert the list into a string first:

x = ["0", "1", "2"]
y = ''.join(x) # converting list into string
z = int(y)

If your list elements are not strings, you'll have to convert them to strings before using str.join:

x = [0, 1, 2]
y = ''.join(map(str, x))
z = int(y)

Also, as stated above, make sure that you're not returning a nested list.

I simply install all the versions of JDK I need and the latest installed becomes default, so I just reinstall the one I want to be default if necessary.

You are lucky that you didn't complete the rebase, so you can still do git rebase --abort. If you had completed the rebase (it rewrites history), things would have been much more complex. Consider tagging the tips of branches before doing potentially damaging operations (particularly history rewriting), that way you can rewind if something blows up.

In addition to the steps below, you may want to also remove the .gitignore file.

• Consider removing the .gitignore file if you want to remove any trace of Git in your project.

• ** Consider leaving the .gitignore file if you would ever want reincorporate Git into the project.

Some frameworks may automatically produce the .gitignore file so you may want to leave it.

Linux, Mac, or Unix based operating systems

Open a terminal and navigate to the directory of your project, i.e. - cd path_to_your_project.

Run this command:

rm -rf .git*

This will remove the Git tracking and metadata from your project. If you want to keep the metadata (such as .gitignore and .gitkeep), you can delete only the tracking by running rm -rf .git.

Windows

Using the command prompt

The rmdir or rd command will not delete/remove any hidden files or folders within the directory you specify, so you should use the del command to be sure that all files are removed from the .git folder.

1. Open the command prompt

   1. Either click Start then Run or hit the key and r at the same time.

   2. Type cmd and hit enter

2. Navigate to the project directory, i.e. - cd path_to_your_project

3. Run these commands

   1. del /F /S /Q /A .git

   2. rmdir .git

The first command removes all files and folder within the .git folder. The second removes the .git folder itself.

No command prompt

1. Open the file explorer and navigate to your project

2. Show hidden files and folders - refer to this article for a visual guide

   1. In the view menu on the toolbar, select Options

   2. In the Advanced Settings section, find Hidden files and Folders under the Files and Folders list and select Show hidden files and folders

3. Close the options menu and you should see all hidden folders and files including the .git folder.

   Delete the .git folder Delete the .gitignore file ** (see note at the top of this answer)

As shown above use 'shown.bs.modal' event which comes in bootstrap 3.

EDIT :-

and just try to open some other url from iframe other than google.com ,it will not allow you to open google.com due to some security threats.

The reason for this is, that Google is sending an "X-Frame-Options: SAMEORIGIN" response header. This option prevents the browser from displaying iFrames that are not hosted on the same domain as the parent page.

This is the simplest example I can think of that conveys the rare cases where this feature is pertinent:

#include <iostream>

class bowl {
public:
    int apples;
    int oranges;
};

int count_fruit(bowl * begin, bowl * end, int bowl::*fruit)
{
    int count = 0;
    for (bowl * iterator = begin; iterator != end; ++ iterator)
        count += iterator->*fruit;
    return count;
}

int main()
{
    bowl bowls[2] = {
        { 1, 2 },
        { 3, 5 }
    };
    std::cout << "I have " << count_fruit(bowls, bowls + 2, & bowl::apples) << " apples\n";
    std::cout << "I have " << count_fruit(bowls, bowls + 2, & bowl::oranges) << " oranges\n";
    return 0;
}

The thing to note here is the pointer passed in to count_fruit. This saves you having to write separate count_apples and count_oranges functions.

You can use PdfBox from Apache which is simple to use and has good performance.

Here is an example of extracting text from a PDF file (you can read more here) :

import java.io.*;
import org.apache.pdfbox.pdmodel.*;
import org.apache.pdfbox.util.*;

public class PDFTest {

 public static void main(String[] args){
 PDDocument pd;
 BufferedWriter wr;
 try {
         File input = new File("C:\\Invoice.pdf");  // The PDF file from where you would like to extract
         File output = new File("C:\\SampleText.txt"); // The text file where you are going to store the extracted data
         pd = PDDocument.load(input);
         System.out.println(pd.getNumberOfPages());
         System.out.println(pd.isEncrypted());
         pd.save("CopyOfInvoice.pdf"); // Creates a copy called "CopyOfInvoice.pdf"
         PDFTextStripper stripper = new PDFTextStripper();
         wr = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(output)));
         stripper.writeText(pd, wr);
         if (pd != null) {
             pd.close();
         }
        // I use close() to flush the stream.
        wr.close();
 } catch (Exception e){
         e.printStackTrace();
        } 
     }
}

UPDATE:

You can get the text using PDFTextStripper:

PDFTextStripper reader = new PDFTextStripper();
String pageText = reader.getText(pd); // PDDocument object created

The previous posters made a little mistake. The accept attribute is only a display filter. It will not validate your entry before submitting.

This attribute forces the file dialog to display the required mime type only. But the user can override that filter. He can choose . and see all the files in the current directory. By doing so, he can select any file with any extension, and submit the form.

So, to answer to the original poster, NO. You cannot restrict the input file to one particular extension by using HTML.

But you can use javascript to test the filename that has been chosen, just before submitting. Just insert an onclick attribute on your submit button and call the code that will test the input file value. If the extension is forbidden, you'll have to return false to invalidate the form. You may even use a jQuery custom validator and so on, to validate the form.

Finally, you'll have to test the extension on the server side too. Same problem about the maximum allowed file size.

The first answer you posted (System is a built-in class...) is pretty spot on.

You can add that the System class contains large portions which are native and that is set up by the JVM during startup, like connecting the System.out printstream to the native output stream associated with the "standard out" (console).

Instead of:

var host = req.get('host');
var origin = req.get('origin');

you can also use:

var host = req.headers.host;
var origin = req.headers.origin;

I often use row_number() as a quick way to discard duplicate records from my select statements. Just add a where clause. Something like...

select a,b,rn 
  from (select a, b, row_number() over (partition by a,b order by a,b) as rn           
          from table) 
 where rn=1;

necromancing

it's just way more easy to make a shared file if possible!

//out
File.AppendAllText("sharedFile.txt", "payload text here");
// in
File.ReadAllText("sharedFile.txt");

Just go to cmd and install pip install pywin32 pythoncom is part of pywin32 for API window extension.... good luck

Any int other than zero is true; false is zero. That way code like this continues to work as expected:

int done = 0;   // `int` could be `bool` just as well

while (!done)
{
     // ...
     done = OS_SUCCESS_CODE == some_system_call ();
}

IMO, bool is an overrated type, perhaps a carry over from other languages. int works just fine as a boolean type.

Here is the implementation of custom filter, which will filter the data using array of values.It will support multiple key object with both array and single value of keys. As mentioned inangularJS API AngularJS filter Doc supports multiple key filter with single value, but below custom filter will support same feature as angularJS and also supports array of values and combination of both array and single value of keys.Please find the code snippet below,

myApp.filter('filterMultiple',['$filter',function ($filter) {
return function (items, keyObj) {
    var filterObj = {
        data:items,
        filteredData:[],
        applyFilter : function(obj,key){
            var fData = [];
            if (this.filteredData.length == 0)
                this.filteredData = this.data;
            if (obj){
                var fObj = {};
                if (!angular.isArray(obj)){
                    fObj[key] = obj;
                    fData = fData.concat($filter('filter')(this.filteredData,fObj));
                } else if (angular.isArray(obj)){
                    if (obj.length > 0){
                        for (var i=0;i<obj.length;i++){
                            if (angular.isDefined(obj[i])){
                                fObj[key] = obj[i];
                                fData = fData.concat($filter('filter')(this.filteredData,fObj));    
                            }
                        }

                    }
                }
                if (fData.length > 0){
                    this.filteredData = fData;
                }
            }
        }
    };
    if (keyObj){
        angular.forEach(keyObj,function(obj,key){
            filterObj.applyFilter(obj,key);
        });
    }
    return filterObj.filteredData;
}
}]);

Usage:

arrayOfObjectswithKeys | filterMultiple:{key1:['value1','value2','value3',...etc],key2:'value4',key3:[value5,value6,...etc]}

Here is a fiddle example with implementation of above "filterMutiple" custom filter. :::Fiddle Example:::

If you really want to create an array rather than a list use either

String[] names = ["lucas", "Fred", "Mary"]

or

def names = ["lucas", "Fred", "Mary"].toArray()

Add the "collapse" class to the alert div and the alert will be "collapsed" (hidden) by default. You can still call it using "show"

<div class="alert alert-error collapse" role="alert" id="passwordsNoMatchRegister">
  <span>
  <p>Looks like the passwords you entered don't match!</p>
  </span>
</div>

enum ? int

yourEnum.ordinal()

int ? enum

EnumType.values()[someInt]

String ? enum

EnumType.valueOf(yourString)

enum ? String

yourEnum.name()

A side-note:
As you correctly point out, the ordinal() may be "unstable" from version to version. This is the exact reason why I always store constants as strings in my databases. (Actually, when using MySql, I store them as MySql enums!)

... just a little bit late :) you might give a try at http://code.google.com/p/tarlog-plugins/. It gives you options like open shell and open explorer from Project Explorer context menu.

There's also http://sourceforge.net/projects/explorerplugin/ but it seems kind of stuck at 2009.

There are two ways to achieve that:

• Use -rpath linker option:

gcc XXX.c -o xxx.out -L$HOME/.usr/lib -lXX -Wl,-rpath=/home/user/.usr/lib

• Use LD_LIBRARY_PATH environment variable - put this line in your ~/.bashrc file:

  export LD_LIBRARY_PATH=/home/user/.usr/lib

This will work even for a pre-generated binaries, so you can for example download some packages from the debian.org, unpack the binaries and shared libraries into your home directory, and launch them without recompiling.

For a quick test, you can also do (in bash at least):

LD_LIBRARY_PATH=/home/user/.usr/lib ./xxx.out

which has the advantage of not changing your library path for everything else.

I have had some recent luck in some simple cases with the code below. I haven't finished all testing but....

EditText input = (EditText) findViewById(R.id.Input);
input.requestFocus();    
input.dispatchTouchEvent(MotionEvent.obtain(SystemClock.uptimeMillis(), SystemClock.uptimeMillis(), MotionEvent.ACTION_DOWN , 0, 0, 0));
input.dispatchTouchEvent(MotionEvent.obtain(SystemClock.uptimeMillis(), SystemClock.uptimeMillis(), MotionEvent.ACTION_UP , 0, 0, 0));

And presto the keyboard shows up.

I am using Visual Studio 2010 express and adding a reference to C:\Program Files\Microsoft ADO.NET Entity Framework 4.1\Binaries\EntityFramework.dll solved the problem.

Not sure which guide you are following, but if you check out this page,

https://www.digitalocean.com/community/tutorials/how-to-install-nginx-on-ubuntu-14-04-lts

It uses another command

ip addr show eth0 | grep inet | awk '{ print $2; }' | sed 's/\/.*$//' 

and also indicates what result is expected.

Symfony 2.3 / 2.4:

This function get's all the errors. The ones on the form like "The CSRF token is invalid. Please try to resubmit the form." as well as additional errors on the form children which have no error bubbling.

private function getErrorMessages(\Symfony\Component\Form\Form $form) {
    $errors = array();

    foreach ($form->getErrors() as $key => $error) {
        if ($form->isRoot()) {
            $errors['#'][] = $error->getMessage();
        } else {
            $errors[] = $error->getMessage();
        }
    }

    foreach ($form->all() as $child) {
        if (!$child->isValid()) {
            $errors[$child->getName()] = $this->getErrorMessages($child);
        }
    }

    return $errors;
}

To get all errors as a string:

$string = var_export($this->getErrorMessages($form), true);

Symfony 2.5 / 3.0:

$string = (string) $form->getErrors(true, false);

I also ran into the same problem awhile ago. I wanted to use the key file, but Amazon says somewhere that you cannot add a key file to an existing EC2 server. For the first Beanstalk application, Amazon preconfigures the application for you. You need to create a new application, and you can configure the EC2 server that runs the Beanstalk app to use an old pem file (ppk if using Putty), or you can create a new one. Now you should be able to SSH.

Then configure, then delete your old app.

If you want MySQL to automatically produce primary keys then you have to tell it when creating the table. You don't have to do this in Oracle.

On the Primary Key you have to include AUTO_INCREMENT. See the example below.

CREATE TABLE `supplier`  
(  
  `ID` int(11) NOT NULL **AUTO_INCREMENT**,  
  `FIRSTNAME` varchar(60) NOT NULL,  
  `SECONDNAME` varchar(100) NOT NULL,  
  `PROPERTYNUM` varchar(50) DEFAULT NULL,  
  `STREETNAME` varchar(50) DEFAULT NULL,  
  `CITY` varchar(50) DEFAULT NULL,  
  `COUNTY` varchar(50) DEFAULT NULL,  
  `COUNTRY` varchar(50) DEFAULT NULL,  
  `POSTCODE` varchar(50) DEFAULT NULL,  
  `HomePHONENUM` bigint(20) DEFAULT NULL,  
  `WorkPHONENUM` bigint(20) DEFAULT NULL,  
  `MobilePHONENUM` bigint(20) DEFAULT NULL,  
  `EMAIL` varchar(100) DEFAULT NULL,  
  PRIMARY KEY (`ID`)  
)

logger.exception will output a stack trace alongside the error message.

For example:

import logging
try:
    1/0
except ZeroDivisionError:
    logging.exception("message")

Output:

ERROR:root:message
Traceback (most recent call last):
  File "<stdin>", line 2, in <module>
ZeroDivisionError: integer division or modulo by zero

@Paulo Cheque notes, "be aware that in Python 3 you must call the logging.exception method just inside the except part. If you call this method in an arbitrary place you may get a bizarre exception. The docs alert about that."

First convert all your pdf files to text files:

for file in *.pdf;do pdftotext "$file"; done

Then use grep as normal. This is especially good as it is fast when you have multiple queries and a lot of PDF files.

When I'm doing something like this I use the onKeyUp event.

<script type="text/javascript">
 function bar() {
      //do stuff
 }
<input type="text" name="foo" onKeyUp="return bar()" />

but if you don't want to use an HTML event you could try to use jQuerys .change() method

$('.target').change(function() {
   //do stuff
});

in this example, the input would have to have a class "target"

if you're going to have multiple text boxes that you want to have done the same thing when their text is changed and you need their data then you could do this:

$('.target').change(function(event) {
   //do stuff with the "event" object as the object that called the method
)};

that way you can use the same code, for multiple text boxes using the same class without having to rewrite any code.

Just create a .bat file with the line

hostname

in it. That's it. Windows also supports the hostname command.

This is not possible. I tried to do so, too. I could figure out the package name and the activity which will be started. But in the end you will get a security exception because of a missing permission you can't declare.

UPDATE:

Regarding the other answer I also recommend to open the App settings screen. I do this with the following code:

    public static void startInstalledAppDetailsActivity(final Activity context) {
    if (context == null) {
        return;
    }
    final Intent i = new Intent();
    i.setAction(Settings.ACTION_APPLICATION_DETAILS_SETTINGS);
    i.addCategory(Intent.CATEGORY_DEFAULT);
    i.setData(Uri.parse("package:" + context.getPackageName()));
    i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    i.addFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
    i.addFlags(Intent.FLAG_ACTIVITY_EXCLUDE_FROM_RECENTS);
    context.startActivity(i);
}

As I don't want to have this in my history stack I remove it using intent flags.

Dim cel As Range, hasNoData As Boolean

    hasNoData = True
    For Each cel In Selection
        hasNoData = hasNoData And IsEmpty(cel)
    Next

This will return True if no cells in Selection contains any data. For a specific range, just substitute RANGE(...) for Selection.

I use type(x) == type(y)

For instance, if I want to check something is an array:

type( x ) == type( [] )

string check:

type( x ) == type( '' ) or type( x ) == type( u'' )

If you want to check against None, use is

x is None

There is an easier method than the other answers here, which require first deserializing into a c# class, and then turning it into a datatable.

It is possible to go directly to a datatable, with JSON.NET and code like this:

DataTable dt = (DataTable)JsonConvert.DeserializeObject(json, (typeof(DataTable)));

The problem is probably you're using a Gradle version rather than 3. go to gradle/wrapper/gradle-wrapper.properties and change the last line to this:

distributionUrl=https\://services.gradle.org/distributions/gradle-3.3-all.zip

.. or if you're not sure it should always be 8 digits, you can pass it as a parameter:

>>> '%0*d' % (8, int(bin(6)[2:]))
'00000110'

Just check if the request has a status code 200. So for example:

if status != 200:
    print("An error has occured. [Status code", status, "]")
else:
    data = response.json() #Only convert to Json when status is OK.
    if not data["elements"]:
        print("Empty JSON")
    else:
        "You can extract data here"

                dr["date"] = DateTime.Parse(row.Cells[0].Text);
                dr["loanbalance"] = double.Parse(row.Cells[1].Text);
                dr["offsetbalance"] = double.Parse(row.Cells[2].Text);

                dr["interestrateperday"] = double.Parse(row.Cells[5].Text);


                dtCalculate.Rows.Add(dr);

            return dtCalculate;

If the checkbox is checked you will get a value for it in your $_POST array. If it isn't the element will be omitted from the array altogether.

The easiest way to test it is like this:

if (isset($_POST['myCheckbox'])) {
  $checkBoxValue = "yes";
} else {
  $checkBoxValue = "no";
}

For your code, add it immediately below the other preprocessing:

$name = $_POST['name']; 
$email_address = $_POST['email']; 
$message = $_POST['tel']; 

if (isset($_POST['newsletter'])) {
  $newsletter = "yes";
} else {
  $newsletter = "no";
}

You'll also need to change the HTML slightly. Change this line:

<input type="checkbox" name="newsletter[]" value="newsletter" checked>i want to sign up for newsletter<br>

to this:

<input type="checkbox" name="newsletter" value="newsletter" checked>i want to sign up   for newsletter<br>
                                      ^^^ remove square brackets here.

note: you may lose values once system restarts.

You can also add system environment variables without Admin rights in Windows 10.

now don't restart, close any opened cmd or powershell, reopen cmd and test by ng version command if you see this it is confirmed working fine.

hope this helps

After updating from TFS 2018 v3 to DevOps Server 2019.0.1 last weekend I now receive this authentication error when attempting to manage security:

TF30063: You are not authorized to access tfs.

I receive this error when attempting to manage security from the Server Administration Console via Application Tier > Administer Security. I also receive the error when I attempt to set permissions via tfssecurity cli tool. I am in the local administrator group and I am listed in the console administration user section.

I'm trying to set permissions because after the update I received several reports from employees that receive errors when they try to access their projects. Those errors are:

TF40049: You do not have licensing rights to access this feature: Code.

I spent 8 hrs working through this issue yesterday, and this is what fixed our problem:

• deleted DevOps server cache. (location of cache listed in devops admin console on server)
• reboot server.

I deleted the cache off the server based on an article I read with the same error, a user was having security/permissions issues with visual studio and they deleted the vs cache on their local machine and it solved their problem. I don't know if deleting the cache or the reboot would have fixed it independently because I did them both as a single troubleshooting step.

Hope this helps someone.

I couldn't find the code in the doc suggested by the accepted answer but I found the updated equivalent here:

File System Programming Guide :: Accessing Files and Directories »

- (NSURL*)applicationDataDirectory {
    NSFileManager* sharedFM = [NSFileManager defaultManager];
    NSArray* possibleURLs = [sharedFM URLsForDirectory:NSApplicationSupportDirectory
                                 inDomains:NSUserDomainMask];
    NSURL* appSupportDir = nil;
    NSURL* appDirectory = nil;

    if ([possibleURLs count] >= 1) {
        // Use the first directory (if multiple are returned)
        appSupportDir = [possibleURLs objectAtIndex:0];
    }

    // If a valid app support directory exists, add the
    // app's bundle ID to it to specify the final directory.
    if (appSupportDir) {
        NSString* appBundleID = [[NSBundle mainBundle] bundleIdentifier];
        appDirectory = [appSupportDir URLByAppendingPathComponent:appBundleID];
    }

    return appDirectory;
}

It discourages use of NSSearchPathForDirectoriesInDomain:

The NSSearchPathForDirectoriesInDomains function behaves like the URLsForDirectory:inDomains: method but returns the directory’s location as a string-based path. You should use the URLsForDirectory:inDomains: method instead.

Here are some other useful directory constants to play with. No doubt not all of these are supported in iOS. Also you can use the NSHomeDirectory() function which:

In iOS, the home directory is the application’s sandbox directory. In OS X, it is the application’s sandbox directory or the current user’s home directory (if the application is not in a sandbox)

From NSPathUtilities.h

NSApplicationDirectory = 1,             // supported applications (Applications)
    NSDemoApplicationDirectory,             // unsupported applications, demonstration versions (Demos)

And finally, some convenience methods in an NSURL category http://club15cc.com/code/ios/easy-ios-file-directory-paths-with-this-handy-nsurl-category

The best solution to me is to create a client service that you'll instantiate with your token an use it to wrap axios.

import axios from 'axios';

const client = (token = null) => {
    const defaultOptions = {
        headers: {
            Authorization: token ? `Token ${token}` : '',
        },
    };

    return {
        get: (url, options = {}) => axios.get(url, { ...defaultOptions, ...options }),
        post: (url, data, options = {}) => axios.post(url, data, { ...defaultOptions, ...options }),
        put: (url, data, options = {}) => axios.put(url, data, { ...defaultOptions, ...options }),
        delete: (url, options = {}) => axios.delete(url, { ...defaultOptions, ...options }),
    };
};

const request = client('MY SECRET TOKEN');

request.get(PAGES_URL);

In this client, you can also retrieve the token from the localStorage / cookie, as you want.

You can compare an array like the below mentioned if the array has some values

it('should check if the array are equal', function() {
        var mockArr = [1, 2, 3];
        expect(mockArr ).toEqual([1, 2, 3]);
 });

But if the array that is returned from some function has more than 1 elements and all are zero then verify by using

expect(mockArray[0]).toBe(0);

Go to the first line from which you would like to delete, and press the keys dG

As far as I know it's not possible... but you can try something like this:

.underline _x000D_
{_x000D_
    color: blue;_x000D_
    border-bottom: 1px solid red;_x000D_
}

<div>_x000D_
    <span class="underline">hello world</span>_x000D_
</div>

Check whether your code contains a namespace which the right most part matches your static class name.

Given the a static Bar class, defined on namespace Foo, implementing a method Jump or a property, chances are you are receiving compiler error because there is also another namespace ending on Bar. Yep, fishi stuff ;-)

If that's so, it means your using a Using Bar; and a Bar.Jump() call, therefore one of the following solutions should fit your needs:

• Fully qualify static class name with according namepace, which result on Foo.Bar.Jump() declaration. You will also need to remove Using Bar; statement
• Rename namespace Bar by a diffente name.

In my case, the foollowing compiler error occurred on a EF (Entity Framework) repository project on an Database.SetInitializer() call:

Member 'Database.SetInitializer<MyDatabaseContext>(IDatabaseInitializer<MyDatabaseContext>)' cannot be accessed with an instance reference; qualify it with a type name instead MyProject.ORM

This error arouse when I added a MyProject.ORM.Database namespace, which sufix (Database), as you might noticed, matches Database.SetInitializer class name.

In this, since I have no control on EF's Database static class and I would also like to preserve my custom namespace, I decided fully qualify EF's Database static class with its namepace System.Data.Entity, which resulted on using the following command, which compilation succeed:

System.Data.Entity.Database.SetInitializer<MyDatabaseContext>(MyMigrationStrategy)

Hope it helps

What would you think of this for 3D ArrayList - can be used similarly to arrays - see the comments in the code:

    import java.util.List;

    /**
     * ArrayList3D simulates a 3 dimensional array,<br>
     * e.g: myValue = arrayList3D.get(x, y, z) is the same as: <br>

     * and<br>
     *      arrayList3D.set(x, y, z, myValue) is the same as:<br> 
     *      array[x][y][z] = myValue; <br>

            if (indexDim1 < max)
                return arrayList3D.get(indexDim1);

            for (int ix = max-1; ix < indexDim1; ix++ ) {
                ar2 = newArrayDim2();
                arrayList3D.add(ar2);
            }
            return ar2;

        }

        private List<T> setOrAddDim3(int indexDim1, int indexDim2) {

            List<List<T>> ar2 = setOrAddDim2(indexDim1);
            List<T>       ar3 = null;

            int max = ar2.size();
            if (indexDim2 < 0)
                indexDim2 = 0;
            if (indexDim2 < max)
                return ar2.get(indexDim2);

            for (int ix = max-1; ix < indexDim2; ix++ ) {
                ar3 = newArrayDim3();
                ar2.add(ar3);
            }
            return ar3;
        }


        public List<List<List<T>>> getArrayList3D() {
            return arrayList3D;
        }

    }

And here is a test code:

        ArrayList3D<Integer> ar = new ArrayList3D<>();

        int max = 3;
        for (int i1 = 0; i1 < max; i1++) {
            for (int i2 = 0; i2 < max; i2++) {
                for (int i3 = 0; i3 < max; i3++) {
                    ar.setOrAddValue(i1, i2, i3, (i3 + 1) + (i2*max) + (i1*max*max));
                    int x = ar.get(i1, i2, i3);
                    System.out.println(" - " + i1 + ", " + i2 + ", " + i3 + " = " + x);
                }
            }
        }

Result output:

• 0, 0, 0 = 1
• 0, 0, 1 = 2
• 0, 0, 2 = 3

No one seems to understand that a retail Nexus One even after being rooted still will not let you browse the file system using DDMS File Explorer. We are talking about real phones here and not the emulator. If you happen to have a Nexus One Developer Phone you can browse the file system using DDMS Filer Explorer, but a retail Nexus One that has been rooted you can't. Got it?

So I hope that answers the question of not being able to use the DDMS File Explorer to browse the file system of a rooted retail Nexus One. After rooting a retail Nexus One there is still something that remains to be done to use DDMS to use the File Explorer to browse the phones File System. I don't know what it is. Maybe someone else knowns.

Explanation by analogy

Imagine that you wrote a letter to your pen pal but that you wrote it in different languages each time.

For example, you might have chosen to write your first letter in Tamil, and the second in German etc.

In order for your friend to translate those letters, your friend would need to:

• (i) identify the language type, and
• (ii) and then translate it accordingly. But identifying a language is not that easy - it's going to take a lot of computational energy. It would be much easier if you wrote the language you are sending across on the top of your letter - that would make life a lot easier for your friend.

So then, in order to highlight the language you are writing in, you simple annotate the language (e.g. "French") on the top of your letter.

How would your friend know or be able to read or distinguish between the different language types you are specifying at the top of your letter? That's easy: you agree upon this beforehand.

Tying the analogy back in with HTML

Because there are different types of data formats which need to be sent over the internet, specifying the data type up front would allow the corresponding client to properly interpret and render the data accordingly to the user.

Why do we have different data formats?

Principally because they serve different purposes and have different abilities.

For example, a PDF format is very different from a picture format - which is also different from a sound format - both serve very different purposes and accordingly are written different prior to being sent over the internet.

I would recommend looking ad joda time. http://www.joda.org/joda-time/

I was afraid of adding another library to my thick project, but it's just easy and fast and smart and awesome. Plus, it plays nice with existing code, to some extent.

You can use the following wrap to make sync call

this.setState((state =>{_x000D_
  return{_x000D_
    something_x000D_
  }_x000D_
})

Here is the clear example of creating array of 10 employee objects, with a constructor that takes parameter:

public class MainClass
{  
    public static void main(String args[])
    {
        System.out.println("Hello, World!");
        //step1 : first create array of 10 elements that holds object addresses.
        Emp[] employees = new Emp[10];
        //step2 : now create objects in a loop.
        for(int i=0; i<employees.length; i++){
            employees[i] = new Emp(i+1);//this will call constructor.
        }
    }
}

class Emp{
    int eno;
    public Emp(int no){
        eno = no;
        System.out.println("emp constructor called..eno is.."+eno);
    }
}

In your client code you are not specifying the content type of the data you are sending - so Jersey is not able to locate the right MessageBodyWritter to serialize the b1 object.

Modify the last line of your main method as follows:

ClientResponse response = resource.type(MediaType.APPLICATION_XML).put(ClientResponse.class, b1);

And add @XmlRootElement annotation to class B on both the server as well as the client sides.

According to their documentation:

An Intent is an object that provides runtime binding between separate components (such as two activities). The Intent represents an app’s "intent to do something." You can use intents for a wide variety of tasks, but most often they’re used to start another activity.

Here is the link with example: http://developer.android.com/training/basics/firstapp/starting-activity.html#BuildIntent

As the document describes, in order to start an activity (you also need to understand what activity is) use the intent like below

/** Called when the user clicks the Send button */
public void sendMessage(View view) {
    Intent intent = new Intent(this, DisplayMessageActivity.class);
    EditText editText = (EditText) findViewById(R.id.edit_message);
    String message = editText.getText().toString();
    intent.putExtra(EXTRA_MESSAGE, message);
    startActivity(intent);
}

WinSCP works fine on Linux under Wine. I installed Wine and WinSCP and had no problems.

Finally I found a neat solution, thanks to Apache Commons:

package com.example;
import org.apache.commons.io.IOUtils;
public class FooTest {
  @Test 
  public void shouldWork() throws Exception {
    String xml = IOUtils.toString(
      this.getClass().getResourceAsStream("abc.xml"),
      "UTF-8"
    );
  }
}

Works perfectly. File src/test/resources/com/example/abc.xml is loaded (I'm using Maven).

If you replace "abc.xml" with, say, "/foo/test.xml", this resource will be loaded: src/test/resources/foo/test.xml

You can also use Cactoos:

package com.example;
import org.cactoos.io.ResourceOf;
import org.cactoos.io.TextOf;
public class FooTest {
  @Test 
  public void shouldWork() throws Exception {
    String xml = new TextOf(
      new ResourceOf("/com/example/abc.xml") // absolute path always!
    ).asString();
  }
}

This may be helpful for some.

My problem exactly is incomplete gradle-1.12-all file download.

Below is screen shot of the Error

1. I re-downloaded the file from the gradle site here and extracted it in path/to/the/gradle, in my case was in C:\Users\maneeOsman\.gradle\wrapper\dists\gradle-1.12-all\2apkk7d25miauqf1pdjp1bm0uo
2. I closed the android studio and reopen it in administrator privilege (Run as administrator).

The android studio starts downloading the necessary files for building and debugging. You can notice that from bottom-left indicator bar.

After this, it is working fine.

See the screen shot below

Just as reference. Taking from D-B answer and comments, I came with this solution which is close to D-B solution. It works fine in all of my cases and it is thread safe. I don't think that using a ConcurrentDictionary would have been ok.

using System;
using System.Collections.Generic;
using System.Xml.Serialization;

namespace HQ.Util.General
{
    public class XmlSerializerHelper
    {
        private static readonly Dictionary<Type, XmlSerializer> _dictTypeToSerializer = new Dictionary<Type, XmlSerializer>();

        public static XmlSerializer GetSerializer(Type type)
        {
            lock (_dictTypeToSerializer)
            {
                XmlSerializer serializer;
                if (! _dictTypeToSerializer.TryGetValue(type, out serializer))
                {
                    var importer = new XmlReflectionImporter();
                    var mapping = importer.ImportTypeMapping(type, null, null);
                    serializer = new XmlSerializer(mapping);
                    return _dictTypeToSerializer[type] = serializer;
                }

                return serializer;
            }
        }
    }
}

Usage:

        if (File.Exists(Path))
        {
            using (XmlTextReader reader = new XmlTextReader(Path))
            {
                // XmlSerializer x  = new XmlSerializer(typeof(T));
                var x = XmlSerializerHelper.GetSerializer(typeof(T));

                try
                {
                    options = (OptionsBase<T>)x.Deserialize(reader);
                }
                catch (Exception ex)
                {
                    Log.Instance.AddEntry(LogType.LogException, "Unable to open Options file: " + Path, ex);
                }
            }
        }

Don't use delete to remove an item from array and use splice() instead.

this.data.splice(this.data.indexOf(msg), 1);

See a similar question: How do I remove a particular element from an array in JavaScript?

Note, that TypeScript is a superset of ES6 (arrays are the same in both TypeScript and JavaScript) so feel free to look for JavaScript solutions even when working with TypeScript.

The question is tagged with ubuntu, but the solution of un-commenting the extension=mysqli.dll is specific to windows. I am confused here?!, anyways, first thing run <? php phpinfo ?> and search for mysql* under Configuration heading. If you don't see such a thing implies you have not installed or enabled php-mysql. So first install php-mysql

sudo apt get install php-mysql

This command will install php-mysql depending on the php you have already installed, so no worries about the version!!.

Then comes the unix specific solution, in the php.ini file un-comment the line

extension=msql.so

verify that msql.so is present in /usr/lib/php/<timestamp_folder>, ELSE

extension=path/to/msql.so

Then finally restart the apache and mysql services, and you should now see the mysql section under Configrations heading in phpinfo page

Specify the paths explicitly:

git diff HEAD:full/path/to/foo full/path/to/bar

Check out the --find-renames option in the git-diff docs.

Use time

Let's say you have the initial dates as strings like these:
date1 = "31/12/2015"
date2 = "01/01/2016"

You can do the following:
newdate1 = time.strptime(date1, "%d/%m/%Y") and newdate2 = time.strptime(date2, "%d/%m/%Y") to convert them to python's date format. Then, the comparison is obvious:

newdate1 > newdate2 will return False
newdate1 < newdate2 will return True

Yes, use this code:

stopAngle = Convert.ToDecimal(159.9);
startAngle = Convert.ToDecimal(355.87);

The problem is harder for arbitrary values. :-)

The simplest way is to just redirect the output, like so:

Compare-Object $(Get-Content c:\user\documents\List1.txt) $(Get-Content c:\user\documents\List2.txt) > c:\user\documents\diff_output.txt

> will cause the output file to be overwritten if it already exists.
>> will append new text to the end of the output file if it already exists.

If you already have the data "for (Parcelable currentHeadline : allHeadlines)," then why are you doing that in a separate thread?

You should poll the data in a separate thread, and when it's finished gathering it, then call your populateTables method on the UI thread:

private void populateTable() {
    runOnUiThread(new Runnable(){
        public void run() {
            //If there are stories, add them to the table
            for (Parcelable currentHeadline : allHeadlines) {
                addHeadlineToTable(currentHeadline);
            }
            try {
                dialog.dismiss();
            } catch (final Exception ex) {
                Log.i("---","Exception in thread");
            }
        }
    });
}

SELECT * 
FROM t1
JOIN t2 USING (id, date)

perhaps you'll need to use INNEER JOIN or where t2.id is not null if you want results only matching both conditions

Example case, when I get file from remote server and save it in local machine

        InputStream in = channel.get("testScp");
        String lf = "OBJECT_FILE";
        FileOutputStream tergetFile = new FileOutputStream(lf);

        int c;
        while ( (c= in.read()) != -1 ) {
            tergetFile.write(c);
        } 

        in.close();
        tergetFile.close();

        channel.disconnect();

Answer in 2020 (Includes Timezone Support)

The problem we were having is that, by default, ISOStrings aren't localized to your timezone. So, this is kinda hacky, but here's how we ended up solving this issue:

/** Imports Moment for time utilities. */
const moment = require("moment-timezone")
moment().tz("America/Chicago").format()

//** Returns now in ISO format in Central Time */
export function getNowISO() {
  return `${moment().toISOString(true).substring(0, 23)}Z`
}

This will leave you with an exact ISO-formatted, localized string.

Important note: Moment now suggests using other packages for new projects.

I built quicktype exactly for this purpose. Just paste your sample JSON and quicktype generates this type hierarchy for your API data:

struct Forecast {
    let hourly: Hourly
    let daily: Daily
    let currently: Currently
    let flags: Flags
    let longitude: Double
    let latitude: Double
    let offset: Int
    let timezone: String
}

struct Hourly {
    let icon: String
    let data: [Currently]
    let summary: String
}

struct Daily {
    let icon: String
    let data: [Datum]
    let summary: String
}

struct Datum {
    let precipIntensityMax: Double
    let apparentTemperatureMinTime: Int
    let apparentTemperatureLowTime: Int
    let apparentTemperatureHighTime: Int
    let apparentTemperatureHigh: Double
    let apparentTemperatureLow: Double
    let apparentTemperatureMaxTime: Int
    let apparentTemperatureMax: Double
    let apparentTemperatureMin: Double
    let icon: String
    let dewPoint: Double
    let cloudCover: Double
    let humidity: Double
    let ozone: Double
    let moonPhase: Double
    let precipIntensity: Double
    let temperatureHigh: Double
    let pressure: Double
    let precipProbability: Double
    let precipIntensityMaxTime: Int
    let precipType: String?
    let sunriseTime: Int
    let summary: String
    let sunsetTime: Int
    let temperatureMax: Double
    let time: Int
    let temperatureLow: Double
    let temperatureHighTime: Int
    let temperatureLowTime: Int
    let temperatureMin: Double
    let temperatureMaxTime: Int
    let temperatureMinTime: Int
    let uvIndexTime: Int
    let windGust: Double
    let uvIndex: Int
    let windBearing: Int
    let windGustTime: Int
    let windSpeed: Double
}

struct Currently {
    let precipProbability: Double
    let humidity: Double
    let cloudCover: Double
    let apparentTemperature: Double
    let dewPoint: Double
    let ozone: Double
    let icon: String
    let precipIntensity: Double
    let temperature: Double
    let pressure: Double
    let precipType: String?
    let summary: String
    let uvIndex: Int
    let windGust: Double
    let time: Int
    let windBearing: Int
    let windSpeed: Double
}

struct Flags {
    let sources: [String]
    let isdStations: [String]
    let units: String
}

It also generates dependency-free marshaling code to coax the return value of JSONSerialization.jsonObject into a Forecast, including a convenience constructor that takes a JSON string so you can quickly parse a strongly typed Forecast value and access its fields:

let forecast = Forecast.from(json: jsonString)!
print(forecast.daily.data[0].windGustTime)

You can install quicktype from npm with npm i -g quicktype or use the web UI to get the complete generated code to paste into your playground.

Note: If you're using MAMP you MUST edit the file using the built-in editor.

Select PHP in the languages section (LH Menu Column) Next, in the main panel next to the default version drop-down click the small arrow pointing to the right. This will launch the php.ini file using the MAMP text editor. Any changes you make to this file will persist after you restart the servers.

Editing the file through Application->MAMP->bin->php->{choosen the version}->php.ini would not work. Since the application overwrites any changes you make.

Needless to say: "Here be dragons!" so please cut and paste a copy of the original and store it somewhere safe in case of disaster.

The way to keep SELECT dbo.fCalculateEstimateDate(647) call working is:

ALTER function [dbo].[fCalculateEstimateDate] (@vWorkOrderID numeric)
Returns varchar(100)  AS
   Declare @Result varchar(100)
   SELECT @Result = [dbo].[fCalculateEstimateDate_v2] (@vWorkOrderID,DEFAULT)
   Return @Result
Begin
End

CREATE function [dbo].[fCalculateEstimateDate_v2] (@vWorkOrderID numeric,@ToDate DateTime=null)
Returns varchar(100)  AS
Begin
  <Function Body>
End
