Here is my solution:

SELECT CONCAT('DROP TABLE `', TABLE_NAME,'`;') 
FROM INFORMATION_SCHEMA.TABLES 
WHERE TABLE_NAME LIKE 'TABLE_PREFIX_GOES_HERE%';

And of course you need to replace TABLE_PREFIX_GOES_HERE with your prefix.

This is more a footnote to a number of the answers above which suggest the use of ON DUPLICATE KEY UPDATE, BEWARE that this is NOT always replication safe, so if you ever plan on growing beyond a single server, you'll want to avoid this and use two queries, one to verify the existence, and then a second to either UPDATE when a row exists, or INSERT when it does not.

Unfortunately (or fortunately) not. The cross-domain policy is there for a reason, if it were easy to get around it then it wouldn't be very effective as a security measure. Other than JSONP, the only option is to proxy the pages using your own server.

With an iframe, they are subject to the same policy. Of course you can display the data from an external domain, you just can't manipulate it.

use this for horizontal divider

<View
    android:layout_width="1dp"
    android:layout_height="match_parent"
    android:background="@color/honeycombish_blue" />

and this for vertical divider

<View
    android:layout_width="match_parent"
    android:layout_height="1dp"
    android:background="@color/honeycombish_blue" />

OR if you can use the LinearLayout divider, for horizontal divider

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" >
    <size android:height="1dp"/>
    <solid android:color="#f6f6f6"/>
</shape>

and in LinearLayout

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:divider="@drawable/divider"
    android:orientation="vertical"
    android:showDividers="middle" >

If you want to user vertical divider then in place of android:height="1dp" in shape use android:width="1dp"

Tip: Don't forget the android:showDividers item.

Here is another way to loop through XML elements using JDOM.

        List<Element> nodeNodes = inputNode.getChildren();
        if (nodeNodes != null) {
            for (Element nodeNode : nodeNodes) {
                List<Element> elements = nodeNode.getChildren(elementName);
                if (elements != null) {
                    elements.size();
                    nodeNodes.removeAll(elements);
                }
            }

for anyone coming here as of post-May 2015: there's a new "-proxy" option that will be included in the next release of openssl: https://rt.openssl.org/Ticket/Display.html?id=2651&user=guest&pass=guest

you need to use -e flag for echo then you can

echo -e "\t\t x"

it depends what sort of t-test you want to do (one sided or two sided dependent or independent) but it should be as simple as:

from scipy.stats import ttest_ind

cat1 = my_data[my_data['Category']=='cat1']
cat2 = my_data[my_data['Category']=='cat2']

ttest_ind(cat1['values'], cat2['values'])
>>> (1.4927289925706944, 0.16970867501294376)

it returns a tuple with the t-statistic & the p-value

see here for other t-tests http://docs.scipy.org/doc/scipy/reference/stats.html

Add your own class, ex: <div class="sidebar right"></div>, with the CSS as

.sidebar.right { 
    float:right
} 

Just Add AjaxControlToolkit.dll to your Reference folder.

On your Project Solution

Right Click on Reference Folder  > Add Reference > browse  AjaxControlToolkit.dll .

Then build.

Don't do nl2br when you save it to the database. Do nl2br when you're displaying the text in HTML. I can strongly recommend to not store any HTML formatting in the database (unless you're using a rich HTML editor as well, in which case it would be silly not to).

A newline \n will just become a newline in the textarea.

It doesn't matter is your app Boot or just raw Spring. There is just enough to inject org.springframework.core.env.Environment to your bean.

@Autowired
private Environment environment;
....

this.environment.getActiveProfiles();

In my opinion this is great solution:

interface PersonRepository extends Repository<Person, UUID> {

    <T> Collection<T> findByLastname(String lastname, Class<T> type);
}

and using it like so

void someMethod(PersonRepository people) {

  Collection<Person> aggregates =
    people.findByLastname("Matthews", Person.class);

  Collection<NamesOnly> aggregates =
    people.findByLastname("Matthews", NamesOnly.class);
}

Here is a simple one-line solution

((int) ((value + 0.005f) * 100)) / 100f

Maybe you can try this: though please note - This pulls the column count, not the row count

 using (SqlDataReader reader = command.ExecuteReader())
 {
     while (reader.Read())
     {
         int count = reader.VisibleFieldCount;
         Console.WriteLine(count);
     }
 }

I go against convention here. I don't like typedef's to base types. I think it's a useless indirection that removes value.

1. When I see the base type in your source I will instantly understand it. If it's a typedef I have to look it up to see what I'm really dealing with.
2. When porting to another compiler or adding another library their set of typedefs may conflict and cause issues that are difficult to debug. I just got done dealing with this in fact. In one library boolean was typedef'ed to int, and in mingw/gcc it's typedef'ed to a char.

If you're using Swift, it's as simple as:

subviews.map { $0.removeFromSuperview }

It's similar in philosophy to the makeObjectsPerformSelector approach, however with a little more type safety.

It's also cleaner to use @JoinTable when an Entity could be the child in several parent/child relationships with different types of parents. To follow up with Behrang's example, imagine a Task can be the child of Project, Person, Department, Study, and Process.

Should the task table have 5 nullable foreign key fields? I think not...

As the other answers didn't address my concern I decided to write my own answer.

The path given in the icon attribute of the md-icon directive is the URL of a .png or .svg file lying somewhere in your static file directory. So you have to put the right path of that file in the icon attribute. p.s put the file in the right directory so that your server could serve it.

Remember md-icon is not like bootstrap icons. Currently they are merely a directive that shows a .svg file.

Update

Angular material design has changed a lot since this question was posted.

Now there are several ways to use md-icon

The first way is to use SVG icons.

<md-icon md-svg-src = '<url_of_an_image_file>'></md-icon>

Example:

<md-icon md-svg-src = '/static/img/android.svg'></md-icon>

or

<md-icon md-svg-src = '{{ getMyIcon() }}'></md-icon>

:where getMyIcon is a method defined in $scope.

or <md-icon md-svg-icon="social:android"></md-icon>

to use this you have to the $mdIconProvider service to configure your application with svg iconsets.

angular.module('appSvgIconSets', ['ngMaterial'])  
  .controller('DemoCtrl', function($scope) {})  
  .config(function($mdIconProvider) {
    $mdIconProvider
      .iconSet('social', 'img/icons/sets/social-icons.svg', 24)
      .defaultIconSet('img/icons/sets/core-icons.svg', 24);    
  });

The second way is to use font icons.

<md-icon md-font-icon="android" alt="android"></md-icon>

<md-icon md-font-icon="fa-magic" class="fa" alt="magic wand"></md-icon>

prior to doing this you have to load the font library like this..

<link href="https://fonts.googleapis.com/icon?family=Material+Icons" rel="stylesheet">

or use font icons with ligatures

<md-icon md-font-library="material-icons">face</md-icon>

<md-icon md-font-library="material-icons">#xE87C;</md-icon>

<md-icon md-font-library="material-icons" class="md-light md-48">face</md-icon>

For further details check our

Angular Material mdIcon Directive documentation

$mdIcon Service Documentation

$mdIconProvider Service Documentation

A simple DELETE before the INSERT would suffice:

DELETE FROM Table2 WHERE Id = (SELECT Id FROM Table1)
INSERT INTO Table2 (Id, name) SELECT Id, name FROM Table1

Switching Table1 for Table2 depending on which table's Id and name pairing you want to preserve.

$('#myForm').on('change', 'input[type=checkbox]', function() {
    this.checked ? this.value = 'apple' : this.value = 'pineapple';
});

Something else to check is make sure viewstate is on (I just solved this yesterday). If you don't have viewstate on, the gridview will be blank until you load it again.

An answer using css flex layout and justify-content

p {
  display: flex;
  justify-content: space-between;
}

<p>
  <span>This text is left aligned</span>
  <span>This text is right aligned</span>
</p>

If you use the string literal exactly as you have shown us, the problem is the ; character at the end. You may not include that in the query string in the JDBC calls.

As you are inserting only a single row, a regular INSERT should be just fine even when inserting multiple rows. Using a batched statement is probable more efficient anywy. No need for INSERT ALL. Additionally you don't need the temporary clob and all that. You can simplify your method to something like this (assuming I got the parameters right):

String query1 = "select substr(to_char(max_data),1,4) as year, " + 
  "substr(to_char(max_data),5,6) as month, max_data " +
  "from dss_fin_user.acq_dashboard_src_load_success " + 
  "where source = 'CHQ PeopleSoft FS'";

String query2 = ".....";

String sql = "insert into domo_queries (clob_column) values (?)";
PreparedStatement pstmt = con.prepareStatement(sql);
StringReader reader = new StringReader(query1);
pstmt.setCharacterStream(1, reader, query1.length());
pstmt.addBatch();

reader = new StringReader(query2);
pstmt.setCharacterStream(1, reader, query2.length());
pstmt.addBatch();

pstmt.executeBatch();   
con.commit();

.img-container {
  display: flex;
}

img {
  margin: auto;
}

this will make the image center in both vertically and horizontally

Here is an alternative method using ls:

(ls x.txt && echo yes) || echo no

If you want to hide any output from ls so you only see yes or no, redirect stdout and stderr to /dev/null:

(ls x.txt >> /dev/null 2>&1 && echo yes) || echo no

You can also use a git-friendly text editor. They show colors on the lines that have been modified, another color for added lines, another color for deleted lines, etc.

A good text editor that does this is GitHub's Atom 1.0.

you can use the following

private async Task<List<string>> GetItems()
{
    return await Task.FromResult(new List<string> 
    { 
      "item1", "item2", "item3" 
    });
}

Say the other guy created bar on top of foo, but you created baz in the meantime and then merged, giving a history of

$ git lola
*   2582152 (HEAD, master) Merge branch 'otherguy'
|\  
| * c7256de (otherguy) bar
* | b7e7176 baz
|/  
* 9968f79 foo

Note: git lola is a non-standard but useful alias.

No dice with git revert:

$ git revert HEAD
fatal: Commit 2582152... is a merge but no -m option was given.

Charles Bailey gave an excellent answer as usual. Using git revert as in

$ git revert --no-edit -m 1 HEAD
[master e900aad] Revert "Merge branch 'otherguy'"
 0 files changed, 0 insertions(+), 0 deletions(-)
 delete mode 100644 bar

effectively deletes bar and produces a history of

$ git lola
* e900aad (HEAD, master) Revert "Merge branch 'otherguy'"
*   2582152 Merge branch 'otherguy'
|\  
| * c7256de (otherguy) bar
* | b7e7176 baz
|/  
* 9968f79 foo

But I suspect you want to throw away the merge commit:

$ git reset --hard HEAD^
HEAD is now at b7e7176 baz

$ git lola
* b7e7176 (HEAD, master) baz
| * c7256de (otherguy) bar
|/  
* 9968f79 foo

As documented in the git rev-parse manual

<rev>^, e.g. HEAD^, v1.5.1^0
A suffix ^ to a revision parameter means the first parent of that commit object. ^<n> means the n-th parent (i.e. <rev>^ is equivalent to <rev>^1). As a special rule, <rev>^0 means the commit itself and is used when <rev> is the object name of a tag object that refers to a commit object.

so before invoking git reset, HEAD^ (or HEAD^1) was b7e7176 and HEAD^2 was c7256de, i.e., respectively the first and second parents of the merge commit.

Be careful with git reset --hard because it can destroy work.

minor correction to mwhs's answer for the windows portion...

The move command does not work for the .\features folder because... well, frankly because Windows is retarded (you can use wildcards with 'move' on files, but apparently wildcards + folders == ignore the command). Anyway, this should work as an alternative to the windows snippet provided for step #2 in his answer.

as a batch file:

@echo off
set eclipse_dir=C:\eclipse_luna

mkdir disabled
mkdir disabled\features 
mkdir disabled\plugins

move plugins\org.eclipse.jpt.* disabled\plugins
for /f %%i in ('dir "%eclipse_dir%\features\org.eclipse.jpt.*" /ad /b') do (
    move "%eclipse_dir%\features\%%i" "%eclipse_dir%\disabled\features\%%i"
)

Try,

  public class Sent
{
    public int MsgID;
    public string Content;
    public int Status;

}

public class Messages
{
    public int MsgID;
    public string Content;
}

  List<Sent> SentList = new List<Sent>() { new Sent() { MsgID = 1, Content = "aaa", Status = 0 }, new Sent() { MsgID = 3, Content = "ccc", Status = 0 } };
            List<Messages> MsgList = new List<Messages>() { new Messages() { MsgID = 1, Content = "aaa" }, new Messages() { MsgID = 2, Content = "bbb" }, new Messages() { MsgID = 3, Content = "ccc" }, new Messages() { MsgID = 4, Content = "ddd" }, new Messages() { MsgID = 5, Content = "eee" }};

            int [] sentMsgIDs = SentList.Select(v => v.MsgID).ToArray();
            List<Messages> result1 = MsgList.Where(o => !sentMsgIDs.Contains(o.MsgID)).ToList<Messages>();

Hope it should help.

/* 
Lines to be commented
*/

NB: multiline comments like this DO NOT NEST. This can be the source of errors. It is generally better to just comment every line with //. Most IDEs allow you to do this quite simply.

Download Git on Msys. Then:

git clone git://project.url.here

The error comes when you try to call sum(x) and x is a factor.

What that means is that one of your columns, though they look like numbers are actually factors (what you are seeing is the text representation)

simple fix, convert to numeric. However, it needs an intermeidate step of converting to character first. Use the following:

family[, 1] <- as.numeric(as.character( family[, 1] ))
family[, 3] <- as.numeric(as.character( family[, 3] ))

For a detailed explanation of why the intermediate as.character step is needed, take a look at this question: How to convert a factor to integer\numeric without loss of information?

It is very simple, just add a property:

public string Value {
  get { return textBox1.Text; }
  set { textBox1.Text = value; }
}

Using the Text property is a bit trickier, the UserControl class intentionally hides it. You'll need to override the attributes to put it back in working order:

[Browsable(true), EditorBrowsable(EditorBrowsableState.Always), Bindable(true)]
[DesignerSerializationVisibility(DesignerSerializationVisibility.Visible)]
public override string Text {
  get { return textBox1.Text; }
  set { textBox1.Text = value; }
}

There's no exact equaliant of language construct die of PHP in Javascript. die in PHP is pretty much equal to System.exit() in Java, which terminates the current script and calls shutdown hooks. As some users suggested; throw Error can be used in some cases, however it never guarantees the termination of the current script. There can be always an exception handling block surrounding your throw statement- unless you call it on the top most level script block, which eventually exits only the script block you're executing.

However it won't prevent the second block from being executed here (prints hello):

<script type="text/javascript">
  throw new Error('test');
</script>
<script type="text/javascript">
  document.write("hello");
</script> 

The top answer didn't do it for me. This did though:

<script type="text/javascript">
    $(document).ready(function(){

        $("#li_13").click(function(){
            if($("#agree").attr('checked')){
                $("#saveForm").fadeIn();
            }
            else
            {
                $("#saveForm").fadeOut();
            }
        });
    });
</script>

Basically when the element #li_13 is clicked, it checks if the element # agree (which is the checkbox) is checked by using the .attr('checked') function. If it is then fadeIn the #saveForm element, and if not fadeOut the saveForm element.

Maybe you can use jQuery selectbox replacement. It's a jQuery plugin.

This function can sum up all the numbers -

 function array(arr){
   var sum = 0;
   for (var i = 0; i< arr.length; i++){
    sum += arr[i];
   }
   console.log(sum);
 }
 array([5, 1, 3, 3])

Personal preference is to use Ignore over SilentlyContinue here because it's not an error at all. Since we're expecting it to potentially be $false let's prevent it (with Ignore) from being put (albeit silently) in the $Error stack.

You can use:

if (Get-Variable 'foo' -Scope 'Global' -ErrorAction 'Ignore') {
    $true
} else {
    $false
}

More tersely:

[bool](gv foo -s global -ea ig)

Output of either:

False

Alternatively

You can trap the error that is raised when the variable doesn't exist.

try {
    Get-Variable foo -Scope Global -ErrorAction 'Stop'
} catch [System.Management.Automation.ItemNotFoundException] {
    Write-Warning $_
}

Outputs:

WARNING: Cannot find a variable with the name 'foo'.

URL url = new URL(yourUrl, "/api/v1/status.xml");

According to the javadocs this constructor just appends whatever resource to the end of your domain, so you would want to create 2 urls:

URL domain = new URL("http://example.com");
URL url = new URL(domain + "/files/resource.xml");

When you create a database in Microsoft SQL Server you can have multiple file groups, where storage is created in multiple places, directories or disks. Each file group can be named. The PRIMARY file group is the default one, which is always created, and so the SQL you've given creates your table ON the PRIMARY file group.

See MSDN for the full syntax.

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()

I have followed the below steps in Macbook.

1. Open terminal
2. type nano ~/.bash_profile and enter
3. Now add the line alias python=python3
4. Press CTRL + o to save it.
5. It will prompt for file name Just hit enter and then press CTRL + x.
6. Now check python version by using the command : python --version

To ensure that a cell will return a date value and not just a string that looks like a date, first you must set the NumberFormat property to a Date format, then put a real date into the cell's content.

Sub test_date_or_String()
 Set c = ActiveCell
 c.NumberFormat = "@"
 c.Value = CDate("03/04/2014")
   Debug.Print c.Value & " is a " & TypeName(c.Value) 'C is a String
 c.NumberFormat = "m/d/yyyy"
   Debug.Print c.Value & " is a " & TypeName(c.Value) 'C is still a String
 c.Value = CDate("03/04/2014")
   Debug.Print c.Value & " is a " & TypeName(c.Value) 'C is a date    
End Sub

I've experienced the same issue on our project. This Microsoft support web page helped me to find the cause. And this solution helped to sort out the issue.

In my case the issue was around ViewStateUserKey as Page.ViewStateUserKey property had an incorrect value (Caused 4 in here). Deleting localhost certificates and recreating them by repairing IIS Expres as mentioned in here fixed the issue.

When you access resultFrame through document.all it only pulls it as an HTML element, not a window frame. You get the same issue if you have a frame fire an event using a "this" self-reference.

Replace:

document.all.resultFrame.Reset();

With:

window.frames.resultFrame.Reset();

Or:

document.all.resultFrame.contentWindow.Reset();

I know this is old but this answer came up in search results. For the next guy - the proposed and accepted answer works, however the code initially submitted in the question is lower-level than it needs to be. Nobody got time for that.

Setting the td height to less than the natural height of its content

Since table cells want to be at least big enough to encase their content, if the content has no apparent height, the cells can be arbitrarily resized.

By resizing the cells, we can control the row height.

One way to do this, is to set the content with an absolute position within the relative cell, and set the height of the cell, and the left and top of the content.

The table-layout property

The second table in the snippet above has table-layout: fixed applied, which causes cells to be given equal width, regardless of their content, within the parent.

According to caniuse.com, there are no significant compatibility issues regarding the use of table-layout as of Sept 12, 2019.

Or simply apply width to specific cells as in the third table.

These methods allow the cell containing the effectively sizeless content created by applying position: absolute to be given some arbitrary girth.

Much more simply...

I really should have thought of this from the start; we can manipulate block level table cell content in all the usual ways, and without completely destroying the content's natural size with position: absolute, we can leave the table to figure out what the width should be.

  width: 100%;_x000D_

I suspect you've got the same problem at least twice.

Here:

namespace TimeTest
{
    class TimeTest
    {
}

... you're declaring a type with the same name as the namespace it's in. Don't do that.

Now you apparently have the same problem with Time2. I suspect if you add:

using Time2;

to your list of using directives, your code will compile. But please, please, please fix the bigger problem: the problematic choice of names. (Follow the link above to find out more details of why it's a bad idea.)

(Additionally, unless you're really interested in writing time-based types, I'd advise you not to do so... and I say that as someone who does do exactly that. Use the built-in capabilities, or a third party library such as, um, mine. Working with dates and times correctly is surprisingly hairy. :)

Procedure Example :

Create Procedure [dbo].[test]
@Name varchar(100),
@ID int Output   
As  
Begin   
SELECT @ID = UserID from tbl_UserMaster where  Name = @Name   
Return;
END     

How to call this procedure

Declare @ID int    
EXECUTE [dbo].[test] 'Abhishek',@ID OUTPUT   
PRINT @ID

I met the same problem just before,the friend at the first floor was right,you called the start() at the wrong time,you should set a listener for prepare() or prepareSync() with this method mediaPlayer.setOnPreparedListener(this); before prepare,in this callback call start().It may resolve your problem. I have tried already.

If you are OK with HTML5 it can be accomplished without any JavaScript code at all...

<input type="number" name="textWeight" id="txtWeight" max="5" min="0" />

Otherwise, something like...

var input = document.getElementById('txtWeight');

input.addEventListener('change', function(e) {
    var num = parseInt(this.value, 10),
        min = 0,
        max = 100;

    if (isNaN(num)) {
        this.value = "";
        return;
    }

    this.value = Math.max(num, min);
    this.value = Math.min(num, max);
});

This will only reset the values when the input looses focus, and clears out any input that can't be parsed as an integer...

OBLIGATORY WARNING

You should always perform adequate server-side validation on inputs, regardless of client-side validation.

You can try this.

XML Document

Save as employees.xml.

<?xml version="1.0" encoding="UTF-8"?>
<Employees>
    <Employee id="1">
        <age>29</age>
        <name>Pankaj</name>
        <gender>Male</gender>
        <role>Java Developer</role>

Parser class

The class have following methods

• List item
• A Method that will return the Employee Name for input ID.
• A Method that will return list of Employees Name with age greater than the input age.
• A Method that will return list of Female Employees Name.

There is a post about this same issue on MSDN:

Getting more information about a serial port in C#

Hi Ravenb,

We can't get the information through the SerialPort type. I don't know why you need this info in your application. However, there's a solved thread with the same question as you. You can check out the code there, and see if it can help you.

If you have any further problem, please feel free to let me know.

Best regards, Bruce Zhou

The link in that post goes to this one:

How to get more info about port using System.IO.Ports.SerialPort

You can probably get this info from a WMI query. Check out this tool to help you find the right code. Why would you care though? This is just a detail for a USB emulator, normal serial ports won't have this. A serial port is simply know by "COMx", nothing more.

I had the same error - in my case it was extra slash in path argument that made the difference.

BAD:

DirectoryEntry directoryEntry = 
    new DirectoryEntry("LDAP://someserver.contoso.com/DC=contoso,DC=com/", 
                       userName, password);

GOOD:

DirectoryEntry directoryEntry = 
    new DirectoryEntry("LDAP://someserver.contoso.com/DC=contoso,DC=com", 
                       userName, password);

This is what I did to get formatted date from front end

  @RequestMapping(value = "/{dateString}", method = RequestMethod.GET)
  @ResponseBody
  public HttpStatus getSomething(@PathVariable @DateTimeFormat(iso = DateTimeFormat.ISO.DATE) String dateString) {
   return OK;
  }

You can use it to get what you want.

A hacky way to solve it without regex is where ',' || x || ',' like '%,3,%'

First of all, you should make an HTML form containing a file input element. You also need to set the form's enctype attribute to multipart/form-data:

<form method="post" enctype="multipart/form-data" action="/upload">
    <input type="file" name="file">
    <input type="submit" value="Submit">
</form>

Assuming the form is defined in index.html stored in a directory named public relative to where your script is located, you can serve it this way:

const http = require("http");
const path = require("path");
const fs = require("fs");

const express = require("express");

const app = express();
const httpServer = http.createServer(app);

const PORT = process.env.PORT || 3000;

httpServer.listen(PORT, () => {
  console.log(`Server is listening on port ${PORT}`);
});

// put the HTML file containing your form in a directory named "public" (relative to where this script is located)
app.get("/", express.static(path.join(__dirname, "./public")));

Once that's done, users will be able to upload files to your server via that form. But to reassemble the uploaded file in your application, you'll need to parse the request body (as multipart form data).

In Express 3.x you could use express.bodyParser middleware to handle multipart forms but as of Express 4.x, there's no body parser bundled with the framework. Luckily, you can choose from one of the many available multipart/form-data parsers out there. Here, I'll be using multer:

You need to define a route to handle form posts:

const multer = require("multer");

const handleError = (err, res) => {
  res
    .status(500)
    .contentType("text/plain")
    .end("Oops! Something went wrong!");
};

const upload = multer({
  dest: "/path/to/temporary/directory/to/store/uploaded/files"
  // you might also want to set some limits: https://github.com/expressjs/multer#limits
});


app.post(
  "/upload",
  upload.single("file" /* name attribute of <file> element in your form */),
  (req, res) => {
    const tempPath = req.file.path;
    const targetPath = path.join(__dirname, "./uploads/image.png");

    if (path.extname(req.file.originalname).toLowerCase() === ".png") {
      fs.rename(tempPath, targetPath, err => {
        if (err) return handleError(err, res);

        res
          .status(200)
          .contentType("text/plain")
          .end("File uploaded!");
      });
    } else {
      fs.unlink(tempPath, err => {
        if (err) return handleError(err, res);

        res
          .status(403)
          .contentType("text/plain")
          .end("Only .png files are allowed!");
      });
    }
  }
);

In the example above, .png files posted to /upload will be saved to uploaded directory relative to where the script is located.

In order to show the uploaded image, assuming you already have an HTML page containing an img element:

<img src="/image.png" />

you can define another route in your express app and use res.sendFile to serve the stored image:

app.get("/image.png", (req, res) => {
  res.sendFile(path.join(__dirname, "./uploads/image.png"));
});

@Filoche's Angular 2 updated solution. Using FormControl

(<Control>this.form.controls['dept']).updateValue(selected.id)

import { FormControl } from '@angular/forms';

(<FormControl>this.form.controls['dept']).setValue(selected.id));

Alternatively you can use @AngularUniversity's solution which uses patchValue

If, like me, you found that @wiggin answer didn't work and images still did not appear in-line, you can use the 'align' property of the html image tag and some breaks to achieve the desired effect, for example:

# Title

<img align="left" src="./documentation/images/A.jpg" alt="Made with Angular" title="Angular" hspace="20"/>
<img align="left" src="./documentation/images/B.png" alt="Made with Bootstrap" title="Bootstrap" hspace="20"/>
<img align="left" src="./documentation/images/C.png" alt="Developed using Browsersync" title="Browsersync" hspace="20"/>
<br/><br/><br/><br/><br/>

## Table of Contents...

Obviously, you have to use more breaks depending on how big the images are: awful yes, but it worked for me so I thought I'd share.

According to http://tools.android.com/tech-docs/new-build-system/migrating-from-eclipse-projects, You have a couple of choices
- simply importing
- pre-exporting first from Eclipse.

Pre-exporting from eclipse may be the better choice if your project contains a lot of relationships that are Eclipse-specific. A.S. cannot 'translate' everything Eclipse can produce. If you want to continue using Eclipse as well as A.S. on this project code, this is the better choice. If you choose this method, please read the above link, there are some important pre-requisites.

Simply importing into AS will let AS 'translate' and rearrange the project, and is the recommended method, especially if you have no intention of returning to Eclipse. In this case, you let the A.S. wizard do everything and you dont need to manually generate gradle files.

It has to do with the way the post-increment operator works. It returns the value of i and then increments the value.

FYI: I also noticed I can mess up a perfectly working spring boot app and prevent it from serving contents from the static folder, if I add a bad rest controller like so

 @RestController
public class BadController {
    @RequestMapping(method= RequestMethod.POST)
    public String someMethod(@RequestParam(value="date", required=false)String dateString, Model model){
        return "foo";
    }
}

In this example, after adding the bad controller to the project, when the browser asks for a file available in static folder, the error response is '405 Method Not Allowed'.

Notice paths are not mapped in the bad controller example.

Instead of calling /usr/bin/gcc, use /usr/bin/c99. This is the Single-Unix-approved way of invoking a C99 compiler. On an Ubuntu system, this points to a script which invokes gcc after having added the -std=c99 flag, which is precisely what you want.

I have resolved the issue using following steps

$ sudo service docker status
$ sudo service docker start
$ sudo docker-compose up

now docker-compose up is working

I need to make a POST request via Curl from the command line. Data for this request is located in a file...

All you need to do is have the --data argument start with a @:

curl -H "Content-Type: text/xml" --data "@path_of_file" host:port/post-file-path

For example, if you have the data in a file called stuff.xml then you would do something like:

curl -H "Content-Type: text/xml" --data "@stuff.xml" host:port/post-file-path

The stuff.xml filename can be replaced with a relative or full path to the file: @../xml/stuff.xml, @/var/tmp/stuff.xml, ...

Do you mean search and replace a string in all files matched by grep?

perl -p -i -e 's/oldstring/newstring/g' `grep -ril searchpattern *`

Edit

Since this seems to be a fairly popular question thought I'd update.

Nowadays I mostly use ack-grep as it's more user-friendly. So the above command would be:

perl -p -i -e 's/old/new/g' `ack -l searchpattern`

To handle whitespace in file names you can run:

ack --print0 -l searchpattern | xargs -0 perl -p -i -e 's/old/new/g'

you can do more with ack-grep. Say you want to restrict the search to HTML files only:

ack --print0 --html -l searchpattern | xargs -0 perl -p -i -e 's/old/new/g'

And if white space is not an issue it's even shorter:

perl -p -i -e 's/old/new/g' `ack -l --html searchpattern`
perl -p -i -e 's/old/new/g' `ack -f --html` # will match all html files

Use a combination of Microsoft specific CSS rules to filter IE11:

<!doctype html>
<html>
 <head>
  <title>IE10/11 Media Query Test</title>
  <meta charset="utf-8">
  <meta http-equiv="X-UA-Compatible" content="IE=edge">
  <style>
    @media all and (-ms-high-contrast:none)
     {
     .foo { color: green } /* IE10 */
     *::-ms-backdrop, .foo { color: red } /* IE11 */
     }
  </style>
 </head>
 <body>
  <div class="foo">Hi There!!!</div>
 </body>
</html>

Filters such as this work because of the following:

When a user agent cannot parse the selector (i.e., it is not valid CSS 2.1), it must ignore the selector and the following declaration block (if any) as well.

<!doctype html>_x000D_
<html>_x000D_
 <head>_x000D_
  <title>IE10/11 Media Query Test</title>_x000D_
  <meta charset="utf-8">_x000D_
  <meta http-equiv="X-UA-Compatible" content="IE=edge">_x000D_
  <style>_x000D_
    @media all and (-ms-high-contrast:none)_x000D_
     {_x000D_
     .foo { color: green } /* IE10 */_x000D_
     *::-ms-backdrop, .foo { color: red } /* IE11 */_x000D_
     }_x000D_
  </style>_x000D_
 </head>_x000D_
 <body>_x000D_
  <div class="foo">Hi There!!!</div>_x000D_
 </body>_x000D_
</html>

I ran into the same problem every time it finds a special character marks it as ??. to solve this, I tried using the encoding: ISO-8859-1

BufferedReader br = new BufferedReader(new InputStreamReader(new FileInputStream("txtPath"),"ISO-8859-1"));

while ((line = br.readLine()) != null) {

}

I hope this can help anyone who sees this post.

You need to have your variables exported. So for example in Linux:

export EnvironmentVariableName=foo

Unexported variables are empty in CMAKE.

UPDATED

For python 3, you should use items() instead of iteritems()

PYTHON 2

for attr, value in k.__dict__.iteritems():
        print attr, value

PYTHON 3

for attr, value in k.__dict__.items():
        print(attr, value)

This will print

'names', [a list with names]
'tweet', [a list with tweet]

Using the Interop you get a range of cells and call the .Merge() method on that range.

eWSheet.Range[eWSheet.Cells[1, 1], eWSheet.Cells[4, 1]].Merge();

Yeah, I'm using tf 2.0-beta and want to enable/disable the default logging. The environment variable and methods in tf1.X don't seem to exist anymore.

I stepped around in PDB and found this to work:

# close the TF2 logger
tf2logger = tf.get_logger()
tf2logger.error('Close TF2 logger handlers')
tf2logger.root.removeHandler(tf2logger.root.handlers[0])

I then add my own logger API (in this case file-based)

logtf = logging.getLogger('DST')
logtf.setLevel(logging.DEBUG)

# file handler
logfile='/tmp/tf_s.log'
fh = logging.FileHandler(logfile)
fh.setFormatter( logging.Formatter('fh %(asctime)s %(name)s %(filename)s:%(lineno)d :%(message)s') )
logtf.addHandler(fh)
logtf.info('writing to %s', logfile)

To disable resizing completely:

textarea {
    resize: none;
}

To allow only vertical resizing:

textarea {
    resize: vertical;
}

To allow only horizontal resizing:

textarea {
    resize: horizontal;
}

Or you can limit size:

textarea {
    max-width: 100px; 
    max-height: 100px;
}

To limit size to parents width and/or height:

textarea {
    max-width: 100%; 
    max-height: 100%;
}

When creating a New Project, under the language of your choice, select Web and then change to .NET Framework 3.5 and you will get the option of creating an ASP.NET WEB Service Application.

if ( ! $("input").is(':checked') )

Doesn't work?

You might also try iterating over the elements like so:

var iz_checked = true;
$('input').each(function(){
   iz_checked = iz_checked && $(this).is(':checked');
});
if ( ! iz_checked )

For right labels use ax.yaxis.set_label_position("right"), i.e.:

f = plt.figure()
ax = f.add_subplot(111)
ax.yaxis.tick_right()
ax.yaxis.set_label_position("right")
plt.plot([2,3,4,5])
ax.set_xlabel("$x$ /mm")
ax.set_ylabel("$y$ /mm")
plt.show()

My compiler will print out 9876543210 when I run this code.

#include <iostream>
int main()
{
    int x = 10;

    while( x --> 0 ) // x goes to 0
    {
        std::cout << x;
    }
}

As expected. The while( x-- > 0 ) actually means while( x > 0). The x-- post decrements x.

while( x > 0 ) 
{
    x--;
    std::cout << x;
}

is a different way of writing the same thing.

It is nice that the original looks like "while x goes to 0" though.

If what you want is to get just a single integer from the query, use:

myCmdObject.ExecuteScalar()

>>> format(3735928559, 'x')
'deadbeef'

To set all existing files and new files to space identation to 2 just put it in your settingns.json (in the root of json):

        "editor.tabSize": 2,
        "editor.insertSpaces": true,
        "editor.detectIndentation":false
 }

you can add the language type of the configuration:

"[javascript]": {
    "editor.tabSize": 2,
    "editor.insertSpaces": true,
    "editor.detectIndentation":false
} 

Here is a solution am using with anular 6.

[readonly]="DateRelatedObject.bool_DatesEdit ? true : false"

plus above given answer

[attr.disabled]="valid == true ? true : null"

did't work for me plus be aware of using null cause it's expecting bool.

I want to extend this topic/answers with the following. As someone mentioned, this auto-generated AssemblyInfo can be an obstacle for the external tools. In my case, using FinalBuilder, I had an issue that AssemblyInfo wasn't getting updated by build action. Apparently, FinalBuilder relies on ~proj file to find location of the AssemblyInfo. I thought, it was looking anywhere under project folder. No. So, changing this

<PropertyGroup>
   <GenerateAssemblyInfo>false</GenerateAssemblyInfo>
</PropertyGroup> 

did only half the job, it allowed custom assembly info if built by VS IDE/MS Build. But I needed FinalBuilder do it too without manual manipulations to assembly info file. I needed to satisfy all programs, MSBuild/VS and FinalBuilder.

I solved this by adding an entry to the existing ItemGroup

<ItemGroup>
   <Compile Remove="Common\**" />
   <Content Remove="Common\**" />
   <EmbeddedResource Remove="Common\**" />
   <None Remove="Common\**" />
   <!-- new added item -->
   <None Include="Properties\AssemblyInfo.cs" />
</ItemGroup>

Now, having this item, FinalBuilder finds location of AssemblyInfo and modifies the file. While action None allows MSBuild/DevEnv ignore this entry and no longer report an error based on Compile action that usually comes with Assembly Info entry in proj files.

C:\Program Files\dotnet\sdk\2.0.2\Sdks\Microsoft.NET.Sdk\build\Microsoft.NET.Sdk.DefaultItems.targets(263,5): error : Duplicate 'Compile' items were included. The .NET SDK includes 'Compile' items from your project directory by default. You can either remove these items from your project file, or set the 'EnableDefaultCompileItems' property to 'false' if you want to explicitly include them in your project file. For more information, see https://aka.ms/sdkimplicititems. The duplicate items were: 'AssemblyInfo.cs'

You're on the right track with using document.getElementById() as you have done for your first two text boxes. Use something like document.getElementById("textbox3") to retrieve the element. Then you can just set its value property: document.getElementById("textbox3").value = answer;

For the "Your answer is: --", I'd recommend wrapping the "--" in a <span/> (e.g. <span id="answerDisplay">--</span>). Then use document.getElementById("answerDisplay").textContent = answer; to display it.

❐ Using java.sql.Date

If your table has a column of type DATE:

• java.lang.String

  The method java.sql.Date.valueOf(java.lang.String) received a string representing a date in the format yyyy-[m]m-[d]d. e.g.:

  ps.setDate(2, java.sql.Date.valueOf("2013-09-04"));
  

• java.util.Date

  Suppose you have a variable endDate of type java.util.Date, you make the conversion thus:

  ps.setDate(2, new java.sql.Date(endDate.getTime());
  

• Current

  If you want to insert the current date:

  ps.setDate(2, new java.sql.Date(System.currentTimeMillis()));
  
  // Since Java 8
  ps.setDate(2, java.sql.Date.valueOf(java.time.LocalDate.now()));
  

❐ Using java.sql.Timestamp

If your table has a column of type TIMESTAMP or DATETIME:

• java.lang.String

  The method java.sql.Timestamp.valueOf(java.lang.String) received a string representing a date in the format yyyy-[m]m-[d]d hh:mm:ss[.f...]. e.g.:

  ps.setTimestamp(2, java.sql.Timestamp.valueOf("2013-09-04 13:30:00");
  

• java.util.Date

  Suppose you have a variable endDate of type java.util.Date, you make the conversion thus:

  ps.setTimestamp(2, new java.sql.Timestamp(endDate.getTime()));
  

• Current

  If you require the current timestamp:

  ps.setTimestamp(2, new java.sql.Timestamp(System.currentTimeMillis()));
  
  // Since Java 8
  ps.setTimestamp(2, java.sql.Timestamp.from(java.time.Instant.now()));
  ps.setTimestamp(2, java.sql.Timestamp.valueOf(java.time.LocalDateTime.now()));
  

If you are using the default template that is created when you select a new ASP.net Web application and selected Individual User accounts as Authentication and trying to create users with Roles so here is the solution. In the Account Controller's Register method which is called using [HttpPost], add the following lines in if condition.

using Microsoft.AspNet.Identity.EntityFramework;

var user = new ApplicationUser { UserName = model.Email, Email = model.Email };

var result = await UserManager.CreateAsync(user, model.Password);

if (result.Succeeded)
{
  var roleStore = new RoleStore<IdentityRole>(new ApplicationDbContext());
  var roleManager = new RoleManager<IdentityRole>(roleStore);
  if(!await roleManager.RoleExistsAsync("YourRoleName"))
     await roleManager.CreateAsync(new IdentityRole("YourRoleName"));

  await UserManager.AddToRoleAsync(user.Id, "YourRoleName");
  await SignInManager.SignInAsync(user, isPersistent:false, rememberBrowser:false);
  return RedirectToAction("Index", "Home");
}

This will create first create a role in your database and then add the newly created user to this role.

This is what I did to extract the piece of the directory:

for path in file_list:
  directories = path.rsplit('\\')
  directories.reverse()
  line_replace_add_directory = line_replace+directories[2]

Thank you for your help.

If you are only looking to point to a different location for you identity file, the you can modify your ~/.ssh/config file with the following entry:

IdentityFile ~/.foo/identity

man ssh_config to find other config options.

Consider using my implementation of "Date.prototype.getWeek", think is more accurate than the others i have seen here :)

Date.prototype.getWeek = function(){
    // We have to compare against the first monday of the year not the 01/01
    // 60*60*24*1000 = 86400000
    // 'onejan_next_monday_time' reffers to the miliseconds of the next monday after 01/01

    var day_miliseconds = 86400000,
        onejan = new Date(this.getFullYear(),0,1,0,0,0),
        onejan_day = (onejan.getDay()==0) ? 7 : onejan.getDay(),
        days_for_next_monday = (8-onejan_day),
        onejan_next_monday_time = onejan.getTime() + (days_for_next_monday * day_miliseconds),
        // If one jan is not a monday, get the first monday of the year
        first_monday_year_time = (onejan_day>1) ? onejan_next_monday_time : onejan.getTime(),
        this_date = new Date(this.getFullYear(), this.getMonth(),this.getDate(),0,0,0),// This at 00:00:00
        this_time = this_date.getTime(),
        days_from_first_monday = Math.round(((this_time - first_monday_year_time) / day_miliseconds));

    var first_monday_year = new Date(first_monday_year_time);

    // We add 1 to "days_from_first_monday" because if "days_from_first_monday" is *7,
    // then 7/7 = 1, and as we are 7 days from first monday,
    // we should be in week number 2 instead of week number 1 (7/7=1)
    // We consider week number as 52 when "days_from_first_monday" is lower than 0,
    // that means the actual week started before the first monday so that means we are on the firsts
    // days of the year (ex: we are on Friday 01/01, then "days_from_first_monday"=-3,
    // so friday 01/01 is part of week number 52 from past year)
    // "days_from_first_monday<=364" because (364+1)/7 == 52, if we are on day 365, then (365+1)/7 >= 52 (Math.ceil(366/7)=53) and thats wrong

    return (days_from_first_monday>=0 && days_from_first_monday<364) ? Math.ceil((days_from_first_monday+1)/7) : 52;
}

I had great luck with OWASP Anti-Samy and an AspectJ advisor on all my Spring Controllers that blocks XSS from getting in.

public class UserInputSanitizer {

    private static Policy policy;
    private static AntiSamy antiSamy;

    private static AntiSamy getAntiSamy() throws PolicyException  {
        if (antiSamy == null) {
            policy = getPolicy("evocatus-default");
            antiSamy = new AntiSamy();
        }
        return antiSamy;

    }

    public static String sanitize(String input) {
        CleanResults cr;
        try {
            cr = getAntiSamy().scan(input, policy);
        } catch (Exception e) {
            throw new RuntimeException(e);
        }
        return cr.getCleanHTML();
    }

    private static Policy getPolicy(String name) throws PolicyException {
        Policy policy = 
            Policy.getInstance(Policy.class.getResourceAsStream("/META-INF/antisamy/" + name + ".xml"));
        return policy;
    }

}

I think this is a better approach then c:out particular if you do a lot of javascript.

I would recommend a little research on Money Pattern. Martin Fowler in his book Analysis pattern has covered this in more detail.

public class Money {

    private static final Currency USD = Currency.getInstance("USD");
    private static final RoundingMode DEFAULT_ROUNDING = RoundingMode.HALF_EVEN;

    private final BigDecimal amount;
    private final Currency currency;   

    public static Money dollars(BigDecimal amount) {
        return new Money(amount, USD);
    }

    Money(BigDecimal amount, Currency currency) {
        this(amount, currency, DEFAULT_ROUNDING);
    }

    Money(BigDecimal amount, Currency currency, RoundingMode rounding) {
        this.currency = currency;      
        this.amount = amount.setScale(currency.getDefaultFractionDigits(), rounding);
    }

    public BigDecimal getAmount() {
        return amount;
    }

    public Currency getCurrency() {
        return currency;
    }

    @Override
    public String toString() {
        return getCurrency().getSymbol() + " " + getAmount();
    }

    public String toString(Locale locale) {
        return getCurrency().getSymbol(locale) + " " + getAmount();
    }   
}

Coming to the usage:

You would represent all monies using Money object as opposed to BigDecimal. Representing money as big decimal will mean that you will have the to format the money every where you display it. Just imagine if the display standard changes. You will have to make the edits all over the place. Instead using the Money pattern you centralize the formatting of money to a single location.

Money price = Money.dollars(38.28);
System.out.println(price);

This is a real-world example.

While working with GWT-Bootstrap V2, it will inject some CSS file, which will override my CSS styles. In order to make my properties to be not overridden, I used !important.

It's entirely possible if your code has enough relative logic to work with.

Simply use the viewport units though for some the math may be a bit more complicated. I used this to prevent list items from bloating certain table columns with much longer text.

ol {max-width: 10vw; padding: 0; overflow: hidden;}

Apparently max-width on colgroup elements do not work which is pretty lame to be dependent entirely on child elements to control something on the parent.

I was also running into this - turns out I was using a community-created AMI - and the default username was niehter root, nor was it ect-user or ubuntu. In fact, I had no idea what it was - till I tried 'root' and the server kindly asked me to login as xxx where xxx is whatever it tells you.

-cheers!

Here are a variety of ways to do this in base R including an alternative aggregate approach. The examples below return means per month, which I think is what you requested. Although, the same approach could be used to return means per person:

Using ave:

my.data <- read.table(text = '
     Name     Month  Rate1     Rate2
     Aira       1      12        23
     Aira       2      18        73
     Aira       3      19        45
     Ben        1      53        19
     Ben        2      22        87
     Ben        3      19        45
     Cat        1      22        87
     Cat        2      67        43
     Cat        3      45        32
', header = TRUE, stringsAsFactors = FALSE, na.strings = 'NA')

Rate1.mean <- with(my.data, ave(Rate1, Month, FUN = function(x) mean(x, na.rm = TRUE)))
Rate2.mean <- with(my.data, ave(Rate2, Month, FUN = function(x) mean(x, na.rm = TRUE)))

my.data <- data.frame(my.data, Rate1.mean, Rate2.mean)
my.data

Using by:

my.data <- read.table(text = '
     Name     Month  Rate1     Rate2
     Aira       1      12        23
     Aira       2      18        73
     Aira       3      19        45
     Ben        1      53        19
     Ben        2      22        87
     Ben        3      19        45
     Cat        1      22        87
     Cat        2      67        43
     Cat        3      45        32
', header = TRUE, stringsAsFactors = FALSE, na.strings = 'NA')

by.month <- as.data.frame(do.call("rbind", by(my.data, my.data$Month, FUN = function(x) colMeans(x[,3:4]))))
colnames(by.month) <- c('Rate1.mean', 'Rate2.mean')
by.month <- cbind(Month = rownames(by.month), by.month)

my.data <- merge(my.data, by.month, by = 'Month')
my.data

Using lapply and split:

my.data <- read.table(text = '
     Name     Month  Rate1     Rate2
     Aira       1      12        23
     Aira       2      18        73
     Aira       3      19        45
     Ben        1      53        19
     Ben        2      22        87
     Ben        3      19        45
     Cat        1      22        87
     Cat        2      67        43
     Cat        3      45        32
', header = TRUE, stringsAsFactors = FALSE, na.strings = 'NA')

ly.mean <- lapply(split(my.data, my.data$Month), function(x) c(Mean = colMeans(x[,3:4])))
ly.mean <- as.data.frame(do.call("rbind", ly.mean))
ly.mean <- cbind(Month = rownames(ly.mean), ly.mean)

my.data <- merge(my.data, ly.mean, by = 'Month')
my.data

Using sapply and split:

my.data <- read.table(text = '
     Name     Month  Rate1     Rate2
     Aira       1      12        23

     Aira       3      19        45
     Ben        1      53        19
     Ben        2      22        87

     Cat        1      22        87
     Cat        2      67        43
     Cat        3      45        32
', header = TRUE, stringsAsFactors = FALSE, na.strings = 'NA')
my.data

sy.mean <- t(sapply(split(my.data, my.data$Month), function(x) colMeans(x[,3:4])))
colnames(sy.mean) <- c('Rate1.mean', 'Rate2.mean')
sy.mean <- data.frame(Month = rownames(sy.mean), sy.mean, stringsAsFactors = FALSE)
my.data <- merge(my.data, sy.mean, by = 'Month')
my.data

Using aggregate:

my.data <- read.table(text = '
     Name     Month  Rate1     Rate2
     Aira       1      12        23

', header = TRUE, stringsAsFactors = FALSE, na.strings = 'NA')

my.summary <- with(my.data, aggregate(list(Rate1, Rate2), by = list(Month), 
                   FUN = function(x) { mon.mean = mean(x, na.rm = TRUE) } ))

my.summary <- do.call(data.frame, my.summary)
colnames(my.summary) <- c('Month', 'Rate1.mean', 'Rate2.mean')
my.summary

my.data <- merge(my.data, my.summary, by = 'Month')
my.data

EDIT: June 28, 2020

Here I use aggregate to obtain the column means of an entire matrix by group where group is defined in an external vector:

my.group <- c(1,2,1,2,2,3,1,2,3,3)

my.data <- matrix(c(   1,    2,    3,    4,    5,
                      10,   20,   30,   40,   50,
                       2,    4,    6,    8,   10,
                      20,   30,   40,   50,   60,
                      20,   18,   16,   14,   12,
                    1000, 1100, 1200, 1300, 1400,

my.data

my.summary <- aggregate(list(my.data), by = list(my.group), FUN = function(x) { my.mean = mean(x, na.rm = TRUE) } )
my.summary

That is not always true; it only works in Windows.
For interacting with terminal in putty, Linux shell,... it will be used for returning the cursor to the beginning of line. following picture shows the usage of that:

Without '\r':

Data comes without '\r' to the putty terminal, it has just '\n'.
it means that data will be printed just in next line.

With '\r':

Data comes with '\r', i.e. string ends with '\r\n'. So the cursor in putty terminal not only will go to the next line but also at the beginning of line

- Each time you append or do any modification with it, it creates a new String object.

- So use append() method of StringBuilder(If thread safety is not important), else use StringBuffer(If thread safety is important.), that will be efficient way to do it.

These two CSS properties can be used to hide the scrollbars:

overflow-y: hidden; // hide vertical
overflow-x: hidden; // hide horizontal

I needed to have a button handler that created a form post to another application within the client's browser. I landed on this question but didn't see an answer that suited my scenario. This is what I came up with:

      protected void Button1_Click(object sender, EventArgs e)
        {

            var formPostText = @"<html><body><div>
<form method=""POST"" action=""OtherLogin.aspx"" name=""frm2Post"">
  <input type=""hidden"" name=""field1"" value=""" + TextBox1.Text + @""" /> 
  <input type=""hidden"" name=""field2"" value=""" + TextBox2.Text + @""" /> 
</form></div><script type=""text/javascript"">document.frm2Post.submit();</script></body></html>
";
            Response.Write(formPostText);
        }

If you run $ heroku logs you may get a "hint" to what the problem is. For me, Heroku could not detect what type of app I was creating. It required me to set the buildpack. Since I was creating a Node.js app, I just had to run $ heroku buildpacks:set https://github.com/heroku/heroku-buildpack-nodejs. You can read more about it here: https://devcenter.heroku.com/articles/buildpacks. No pushing issues after that.

I know this is an old question, but still posting this here incase someone else gets stuck.

\copy which is a postgres command can work for any user. Don't know if it works for \dt or not, but general syntax is reproduced from the following link Postgres SQL copy syntax

\copy (select * from tempTable limit 100) to 'filenameinquotes' with header delimiter as ','

The above will save the output of the select query in the filename provided as a csv file

EDIT:

For my psql server the following command works this is an older version v8.5

copy (select * from table1) to 'full_path_filename' csv header;

if you have HTML like this

<tr>
 <td><span class="spanUser" userid="123"></span></td>
 <td><span class="spanUser" userid="123"></span></td>
</tr>

where userid="123" is a custom attribute that you can populate dynamically when you build the table,

you can use something like

  $(".spanUser").live("click", function () {

        var span = $(this);   
        var userid = $(this).attr('userid');

        var currentURL = window.location.protocol + '//' + window.location.host;
        var url = currentURL + "/Account/DeleteUser/" + userid;

        $.post(url, function (data) {
          if (data) {
                   var tdTAG = span.parent(); // GET PARENT OF SPAN TAG
                   var trTAG = tdTAG.parent(); // GET PARENT OF TD TAG
                   trTAG.remove(); // DELETE TR TAG == DELETE AN ENTIRE TABLE ROW 
             } else {
                alert('Sorry, there is some error.');
            }

     });

So in that case you don't know the class or id of the TR tag but anyway you are able to delete it.

Along with the other answers mentioned by Barmar and Joni, I've noticed that I sometimes have to leave a blank line before and after my EOF when using <<-EOF.

The API docs on link_to show some examples of adding querystrings to both named and oldstyle routes. Is this what you want?

link_to can also produce links with anchors or query strings:

link_to "Comment wall", profile_path(@profile, :anchor => "wall")
#=> <a href="/profiles/1#wall">Comment wall</a>

link_to "Ruby on Rails search", :controller => "searches", :query => "ruby on rails"
#=> <a href="/searches?query=ruby+on+rails">Ruby on Rails search</a>

link_to "Nonsense search", searches_path(:foo => "bar", :baz => "quux")
#=> <a href="/searches?foo=bar&amp;baz=quux">Nonsense search</a>

If notepad is already started, you should write:

// import the function in your class
[DllImport ("User32.dll")]
static extern int SetForegroundWindow(IntPtr point);

//...

Process p = Process.GetProcessesByName("notepad").FirstOrDefault();
if (p != null)
{
    IntPtr h = p.MainWindowHandle;
    SetForegroundWindow(h);
    SendKeys.SendWait("k");
}

GetProcessesByName returns an array of processes, so you should get the first one (or find the one you want).

If you want to start notepad and send the key, you should write:

Process p = Process.Start("notepad.exe");
p.WaitForInputIdle();
IntPtr h = p.MainWindowHandle;
SetForegroundWindow(h);
SendKeys.SendWait("k");

The only situation in which the code may not work is when notepad is started as Administrator and your application is not.

Now with css3 you could try to use calc()

.main{
  height: calc(100% - 111px);
}

have a look at this answer: Div width 100% minus fixed amount of pixels

Try this example.

All that metadata is held in the DB2 catalog tables in the SYSIBM 'schema'. It varies for the DB2/z mainframe product and the DB2/LUW distributed product but they're coming closer and closer with each release.

IBM conveniently place all their manuals up on the publib site for the world to access. My area of expertise, DB2/z, has the pages you want here.

There are a number of tables there that you'll need to reference:

SYSTABLES        for table information.
SYSINDEXES    \
SYSINDEXPART   + for index information.
SYSKEYS       /
SYSCOLUMNS       for column information.

The list of all information centers is here which should point you to the DB2/LUW version if that's your area of interest.

When you use git push origin :staleStuff, it automatically removes origin/staleStuff, so when you ran git remote prune origin, you have pruned some branch that was removed by someone else. It's more likely that your co-workers now need to run git prune to get rid of branches you have removed.

So what exactly git remote prune does? Main idea: local branches (not tracking branches) are not touched by git remote prune command and should be removed manually.

Now, a real-world example for better understanding:

You have a remote repository with 2 branches: master and feature. Let's assume that you are working on both branches, so as a result you have these references in your local repository (full reference names are given to avoid any confusion):

• refs/heads/master (short name master)
• refs/heads/feature (short name feature)
• refs/remotes/origin/master (short name origin/master)
• refs/remotes/origin/feature (short name origin/feature)

Now, a typical scenario:

1. Some other developer finishes all work on the feature, merges it into master and removes feature branch from remote repository.
2. By default, when you do git fetch (or git pull), no references are removed from your local repository, so you still have all those 4 references.
3. You decide to clean them up, and run git remote prune origin.
4. git detects that feature branch no longer exists, so refs/remotes/origin/feature is a stale branch which should be removed.
5. Now you have 3 references, including refs/heads/feature, because git remote prune does not remove any refs/heads/* references.

It is possible to identify local branches, associated with remote tracking branches, by branch.<branch_name>.merge configuration parameter. This parameter is not really required for anything to work (probably except git pull), so it might be missing.

(updated with example & useful info from comments)

Doing password checks on client side is unsafe especially when the password is hard coded.

The safest way is password checking on server side, but even then the password should not be transmitted plain text.

Checking the password client side is possible in a "secure way":

• The password needs to be hashed
• The hashed password is used as part of a new url

Say "abc" is your password so your md5 would be "900150983cd24fb0d6963f7d28e17f72" (consider salting!). Now build a url containing the hash (like http://yourdomain.com/90015...f72.html).

Just use wpdb->insert(tablename, coloumn, format) and wp will prepare that's query

<?php
global $wpdb;
$wpdb->insert("wp_submitted_form", array(
   "name" => $name,
   "email" => $email,
   "phone" => $phone,
   "country" => $country,
   "course" => $course,
   "message" => $message,
   "datesent" => $now ,
));
?>

If you or another dev will not work on branchB further, I think it's better to keep commits in order to make reverts without headaches. So ;

git checkout branchA
git pull --rebase branchB

It's important that branchB shouldn't be used anymore.

I used this code to show the dialog at the bottom of the screen:

Dialog dlg = <code to create custom dialog>;

Window window = dlg.getWindow();
WindowManager.LayoutParams wlp = window.getAttributes();

wlp.gravity = Gravity.BOTTOM;
wlp.flags &= ~WindowManager.LayoutParams.FLAG_DIM_BEHIND;
window.setAttributes(wlp);

This code also prevents android from dimming the background of the dialog, if you need it. You should be able to change the gravity parameter to move the dialog about

private void showPictureialog() {
    final Dialog dialog = new Dialog(this,
            android.R.style.Theme_Translucent_NoTitleBar);

    // Setting dialogview
    Window window = dialog.getWindow();
    window.setGravity(Gravity.CENTER);

    window.setLayout(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT);
    dialog.setTitle(null);
    dialog.setContentView(R.layout.selectpic_dialog);
    dialog.setCancelable(true);

    dialog.show();
}

you can customize you dialog based on gravity and layout parameters change gravity and layout parameter on the basis of your requirenment

Scraping it to JSON with Node.js would be fun :)

Here is a simple function for converting a byte buffer to string:

public String byteBufferToString(ByteBuffer bufferData) {
    byte[] buffer = new byte[bufferData.readableByteCount()];
    // read bufferData and insert into buffer 
    data.read(buffer);
    // CharsetUtil supports UTF_16, ASCII, and many more
    String text = new String(buffer, CharsetUtil.UTF_8);
    System.out.println("Text: "+text);
    return text;
}

Not to belabor the point, but if you are working in a Dockerfile, you would solve this particular issue with Composer by installing the unzip utility. Below is an example using the official PHP image to install unzip and the zip PHP extension for good measure.

FROM php:7.4-apache

# Install Composer
COPY --from=composer /usr/bin/composer /usr/bin/composer

# Install unzip utility and libs needed by zip PHP extension 
RUN apt-get update && apt-get install -y \
    zlib1g-dev \
    libzip-dev \
    unzip
RUN docker-php-ext-install zip

This is a helpful GitHub issue where the above is lovingly lifted from.

mvc:annotation-driven is a tag added in Spring 3.0 which does the following:

1. Configures the Spring 3 Type ConversionService (alternative to PropertyEditors)
2. Adds support for formatting Number fields with @NumberFormat
3. Adds support for formatting Date, Calendar, and Joda Time fields with @DateTimeFormat, if Joda Time is on the classpath
4. Adds support for validating @Controller inputs with @Valid, if a JSR-303 Provider is on the classpath
5. Adds support for support for reading and writing XML, if JAXB is on the classpath (HTTP message conversion with @RequestBody/@ResponseBody)
6. Adds support for reading and writing JSON, if Jackson is o n the classpath (along the same lines as #5)

context:annotation-config Looks for annotations on beans in the same application context it is defined and declares support for all the general annotations like @Autowired, @Resource, @Required, @PostConstruct etc etc.

You can use the iOS simulator to do this. You need to enable "Developer Mode" on Safari (Preferences -> Advanced).

Then open the website you want to debug in the iOS simulator. Go back to safari and under Develop you will see the simulator and the tabs open on safari.

If you want to test an actual device, then just plug it into your computer and it should show there too.

That's how I do it.

from tkinter import *
from PIL import ImageTk, Image

window = Tk()
window.geometry("1000x300")

path = "1.jpg"

image = PhotoImage(Image.open(path))

panel = Label(window, image = image)

panel.pack()

window.mainloop()

Go to settings section of your repository and choose master branch at the Source section and click save button after that refresh the page and you will be able to see the link of your page!.

UPDATE your_table
SET your_field = REPLACE(your_field, 'articles/updates/', 'articles/news/')
WHERE your_field LIKE '%articles/updates/%'

Now rows that were like

http://www.example.com/articles/updates/43

will be

http://www.example.com/articles/news/43

Yes, Spring framework logging is very detailed, You did not mention in your post, if you are already using a logging framework or not. If you are using log4j then just add spring appenders to the log4j config (i.e to log4j.xml or log4j.properties), If you are using log4j xml config you can do some thing like this

<category name="org.springframework.beans">
    <priority value="debug" />
</category>

or

<category name="org.springframework">
    <priority value="debug" />
</category>

I would advise you to test this problem in isolation using JUnit test, You can do this by using spring testing module in conjunction with Junit. If you use spring test module it will do the bulk of the work for you it loads context file based on your context config and starts container so you can just focus on testing your business logic. I have a small example here

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations={"classpath:springContext.xml"})
@Transactional
public class SpringDAOTest 
{
    @Autowired
    private SpringDAO dao;

    @Autowired
    private ApplicationContext appContext;

    @Test
    public void checkConfig()
    {
        AnySpringBean bean =  appContext.getBean(AnySpringBean.class);
        Assert.assertNotNull(bean);
    }
}

UPDATE

I am not advising you to change the way you load logging but try this in your dev environment, Add this snippet to your web.xml file

<context-param>
    <param-name>log4jConfigLocation</param-name>
    <param-value>/WEB-INF/log4j.xml</param-value>
</context-param>

<listener>
    <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>
</listener>

UPDATE log4j config file

I tested this on my local tomcat and it generated a lot of logging on application start up. I also want to make a correction: use debug not info as @Rayan Stewart mentioned.

Let me add some more use case of the square-bracket notation. If you want to access a property say x-proxy in a object, then - will be interpreted wrongly. Their are some other cases too like space, dot, etc., where dot operation will not help you. Also if u have the key in a variable then only way to access the value of the key in a object is by bracket notation. Hope you get some more context.

you need to alter session

you can try before insert

 sql : alter session set nls_date_format = 'YYYY-MM-DD HH24:MI:SS'

This should work in your case without removing namespaces:

XmlNode idNode = myXmlDoc.GetElementsByTagName("id")[0];

Maybe you are out of inodes. Try df -i

                     2591792  136322 2455470    6% /home
/dev/sdb1            1887488 1887488       0  100% /data

Disk used 6% but inode table full.

1. Make sure markup (svc) file has service attribute with namespace.classname and codebehind will be classname.svc.cs

2. Rebuild the solution

3. Restart the app pools from local IIS once.

Maybe, e.g.,

SAVE_IFS="$IFS"
IFS=","
FOOJOIN="${FOO[*]}"
IFS="$SAVE_IFS"

echo "$FOOJOIN"

If you disable the maintain aspect ratio in options then it uses the available height:

var chart = new Chart('blabla', {
                type: 'bar',
                data: {
                },
                options: {
                    maintainAspectRatio: false,
                }
            });

You'll see this in all the directives:

When you use brackets, it means you're passing a bindable property (a variable).

  <a [routerLink]="routerLinkVariable"></a>

So this variable (routerLinkVariable) could be defined inside your class and it should have a value like below:

export class myComponent {

    public routerLinkVariable = "/home"; // the value of the variable is string!

But with variables, you have the opportunity to make it dynamic right?

export class myComponent {

    public routerLinkVariable = "/home"; // the value of the variable is string!


    updateRouterLinkVariable(){

        this.routerLinkVariable = '/about';
    }

Where as without brackets you're passing string only and you can't change it, it's hard coded and it'll be like that throughout your app.

<a routerLink="/home"></a>

UPDATE :

The other speciality about using brackets specifically for routerLink is that you can pass dynamic parameters to the link you're navigating to:

So adding a new variable

export class myComponent {
        private dynamicParameter = '129';
        public routerLinkVariable = "/home"; 

Updating the [routerLink]

  <a [routerLink]="[routerLinkVariable,dynamicParameter]"></a>

When you want to click on this link, it would become:

  <a href="/home/129"></a>

If this is for a non-Rails project, I'd use String#index:

"foobar".index("foo") == 0  # => true

For Xamarin.Android I have created this extension.

public static class ViewExtensions
{
    public static void FocusEditText(this EditText editText, Activity activity)
    {
        if (editText.RequestFocus())
        {
            InputMethodManager imm = (InputMethodManager)activity.GetSystemService(Context.InputMethodService);
            imm.ShowSoftInput(editText, ShowFlags.Implicit);
        }
    }
}

You could do it easily using

File.AppendAllText("date.txt", DateTime.Now.ToString());

If you need newline

File.AppendAllText("date.txt", 
                   DateTime.Now.ToString() + Environment.NewLine);

Anyway if you need your code do this:

TextWriter tw = new StreamWriter("date.txt", true);

with second parameter telling to append to file.
Check here StreamWriter syntax.

Maybe not an advanced technique, but one I see all the time that drives me crazy:

if (x == 1)
{
   x = 2;
}
else
{
   x = 3;
}

can be condensed to:

x = (x==1) ? 2 : 3;

If you use jquery then you can also do like this,

 $(document).on("keydown", '.class_name', function (event) {
    if (event.keyCode == 37) {
        console.log('left arrow pressed');
    }
    if (event.keyCode == 38) {
        console.log('up arrow pressed');
    }
    if (event.keyCode == 39) {
        console.log('right arrow pressed');
    }
    if (event.keyCode == 40) {
        console.log('down arrow pressed');
    }
 });

Use which.min:

df <- data.frame(Name=c('A','B','C','D'), Amount=c(150,120,175,160))
df[which.min(df$Amount),]

> df[which.min(df$Amount),]
  Name Amount
2    B    120

From the help docs:

Determines the location, i.e., index of the (first) minimum or maximum of a numeric (or logical) vector.

No need for array. Just use something like this:

Sub ARRAYER()

    Dim Rng As Range
    Dim Number_of_Sims As Long
    Dim i As Long
    Number_of_Sims = 10

    Set Rng = Range("C4:G4")
    For i = 1 To Number_of_Sims
       Rng.Offset(i, 0).Value = Rng.Value
       Worksheets("Sheetname").Calculate   'replacing Sheetname with name of your sheet
    Next

End Sub

"Requery" is indeed what you what you want to run, but you could do that in Form A's "On Got Focus" event. If you have code in your Form_Load, perhaps you can move it to Form_Got_Focus.

I would also recommend to search for fields which all have the same value, not just NULL.

That is, for each column in each table do the query:

SELECT COUNT(DISTINCT field) FROM tableName

and concentrate on those which return 1 as a result.

I combined some of Flavio's answer to this small solution.

.hidden-ul-bullets li {
    list-style: none;
}
.hidden-ul-bullets ul {
    margin-left: 0.25em; // for my purpose, a little indentation is wished
}

The decision about bullets is made at an enclosing element, typically a div. The drawback (or todo) of my solution is that the liststyle removal also applies to ordered lists.

There is a possibility to use "volumes_from" as a workaround until depends_on feature (discussed below) is introduced. All you have to do is change your docker-compose file as below:

nginx:
  image: nginx
  ports:
    - "42080:80"
  volumes:
    - ./config/docker/nginx/default.conf:/etc/nginx/conf.d/default.conf:ro
  volumes_from:
    - php

php:
  build: config/docker/php
  ports:
    - "42022:22"
  volumes:
    - .:/var/www/html
  env_file: config/docker/php/.env.development

mongo:
  image: mongo
  ports:
    - "42017:27017"
  volumes:
    - /var/mongodata/wa-api:/data/db
  command: --smallfiles

One big caveat in the above approach is that the volumes of php are exposed to nginx, which is not desired. But at the moment this is one docker specific workaround that could be used.

depends_on feature This probably would be a futuristic answer. Because the functionality is not yet implemented in Docker (as of 1.9)

There is a proposal to introduce "depends_on" in the new networking feature introduced by Docker. But there is a long running debate about the same @ https://github.com/docker/compose/issues/374 Hence, once it is implemented, the feature depends_on could be used to order the container start-up, but at the moment, you would have to resort to one of the following:

1. make nginx retry until the php server is up - I would prefer this one
2. use volums_from workaround as described above - I would avoid using this, because of the volume leakage into unnecessary containers.

Just to complement Mr @potatosalad answer.

You don't actually need to access the function scope to get the result on the onload callback, you can freely do the following on the event parameter:

var arrayBuffer;
var fileReader = new FileReader();
fileReader.onload = function(event) {
    arrayBuffer = event.target.result;
};
fileReader.readAsArrayBuffer(blob);

Why this is better? Because then we may use arrow function without losing the context

var fileReader = new FileReader();
fileReader.onload = (event) => {
    this.externalScopeVariable = event.target.result;
};
fileReader.readAsArrayBuffer(blob);

This may help you.

$today = date("m-d-Y H:i:s");
$thisMonth =date("m");
$thisYear = date("y");
$expectedDate = ($thisMonth+1)."-08-$thisYear 23:58:00";


if (strtotime($expectedDate) > strtotime($today)) {
    echo "Expected date is greater then current date";
    return ;
} else
{
 echo "Expected date is lesser then current date";
}

if you don't like the double brackets or you don't want to write a function, you can just use a variable.

$path = Test-Path C:\Code
if (!$path) {
    write "it doesn't exist!"
}

This sort of thing is one of the logistical reasons why Abort is deprecated. First and foremost, do not use Thread.Abort() to cancel or stop a thread if at all possible. Abort() should only be used to forcefully kill a thread that is not responding to more peaceful requests to stop in a timely fashion.

That being said, you need to provide a shared cancellation indicator that one thread sets and waits while the other thread periodically checks and gracefully exits. .NET 4 includes a structure designed specifically for this purpose, the CancellationToken.

You should set a TimeZone in your DateFormat, otherwise it will use the default one (depending on the settings of the computer).

Just changed Amber's COUNT(*) to COUNT(1) for the better performance.

SELECT name, COUNT(1) as count 
FROM tablename 
GROUP BY name 
ORDER BY count DESC;

I created jquery.backgroundSize.js: a 1.5K jquery plugin that can be used as a IE8 fallback for "cover" and "contain" values. Have a look at the demo.

A form action set to a JavaScript function is not widely supported, I'm surprised it works in FireFox.

The best is to just set form action to your PHP script; if you need to do anything before submission you can just add to onsubmit

Edit turned out you didn't need any extra function, just a small change here:

function validateFormOnSubmit(theForm) {
    var reason = "";
    reason += validateName(theForm.name);
    reason += validatePhone(theForm.phone);
    reason += validateEmail(theForm.emaile);

    if (reason != "") {
        alert("Some fields need correction:\n" + reason);
    } else {
        simpleCart.checkout();
    }
    return false;
}

Then in your form:

<form action="#" onsubmit="return validateFormOnSubmit(this);">

Even if technically feasible, is NOT a good approach. When You say: "The splash screen would have buttons for each room that would allow you to jump to any point on the walk through." So you want to pass through appdelegate to call these controllers via tohc events on buttons?

This approach does not follow Apple guidelines and has a lot of drawbacks.

using sizeof()

char h[] = "hello";
printf("%d\n",sizeof(h)-1); //Output = 5

using string.h

using function (strlen implementation)

int strsize(const char* str);

    char h[] = "hello";
    printf("%d\n",strsize(h)); //Output = 5

According to the official documentation:

Fragment#setTargetFragment

Optional target for this fragment. This may be used, for example, if this fragment is being started by another, and when done wants to give a result back to the first. The target set here is retained across instances via FragmentManager#putFragment.

Fragment#getTargetFragment

Return the target fragment set by setTargetFragment(Fragment, int).

So you can do this:

// In your fragment

public class MyFragment extends Fragment implements OnClickListener {
    private void showDialog() {
        DialogFragment dialogFrag = MyDialogFragment.newInstance(this);
        // Add this
        dialogFrag.setTargetFragment(this, 0);
        dialogFrag.show(getFragmentManager, null);
    }
    ...
}

// then

public class MyialogFragment extends DialogFragment {
    @Override
    public void onAttach(Context context) {
        super.onAttach(context);
        // Then get it
        Fragment fragment = getTargetFragment();
        if (fragment instanceof OnClickListener) {
            listener = (OnClickListener) fragment;
        } else {
            throw new RuntimeException("you must implement OnClickListener");
        }
    }
    ...
}

I think the fastest way—without using lookup tables and popcount—is the following. It counts the set bits with just 12 operations.

int popcount(int v) {
    v = v - ((v >> 1) & 0x55555555);                // put count of each 2 bits into those 2 bits
    v = (v & 0x33333333) + ((v >> 2) & 0x33333333); // put count of each 4 bits into those 4 bits  
    return c = ((v + (v >> 4) & 0xF0F0F0F) * 0x1010101) >> 24;
}

It works because you can count the total number of set bits by dividing in two halves, counting the number of set bits in both halves and then adding them up. Also know as Divide and Conquer paradigm. Let's get into detail..

v = v - ((v >> 1) & 0x55555555); 

The number of bits in two bits can be 0b00, 0b01 or 0b10. Lets try to work this out on 2 bits..

 ---------------------------------------------
 |   v    |   (v >> 1) & 0b0101   |  v - x   |
 ---------------------------------------------
   0b00           0b00               0b00   
   0b01           0b00               0b01     
   0b10           0b01               0b01
   0b11           0b01               0b10

This is what was required: the last column shows the count of set bits in every two bit pair. If the two bit number is >= 2 (0b10) then and produces 0b01, else it produces 0b00.

v = (v & 0x33333333) + ((v >> 2) & 0x33333333); 

This statement should be easy to understand. After the first operation we have the count of set bits in every two bits, now we sum up that count in every 4 bits.

v & 0b00110011         //masks out even two bits
(v >> 2) & 0b00110011  // masks out odd two bits

We then sum up the above result, giving us the total count of set bits in 4 bits. The last statement is the most tricky.

c = ((v + (v >> 4) & 0xF0F0F0F) * 0x1010101) >> 24;

Let's break it down further...

v + (v >> 4)

It's similar to the second statement; we are counting the set bits in groups of 4 instead. We know—because of our previous operations—that every nibble has the count of set bits in it. Let's look an example. Suppose we have the byte 0b01000010. It means the first nibble has its 4bits set and the second one has its 2bits set. Now we add those nibbles together.

0b01000010 + 0b01000000

It gives us the count of set bits in a byte, in the first nibble 0b01100010 and therefore we mask the last four bytes of all the bytes in the number (discarding them).

0b01100010 & 0xF0 = 0b01100000

Now every byte has the count of set bits in it. We need to add them up all together. The trick is to multiply the result by 0b10101010 which has an interesting property. If our number has four bytes, A B C D, it will result in a new number with these bytes A+B+C+D B+C+D C+D D. A 4 byte number can have maximum of 32 bits set, which can be represented as 0b00100000.

All we need now is the first byte which has the sum of all set bits in all the bytes, and we get it by >> 24. This algorithm was designed for 32 bit words but can be easily modified for 64 bit words.

If you have headers in the markdown files, you can directly link them in the file.

Markdown Header -

## The Header

this will generate an implicit id #the-header (replace internal spaces with hyphens and make lowercase).

To navigate to this id, you can create the link like this:

[Link to Header](#the-header)

This is equivalent to:

<a href="#the-header">Link to Header</a>

Please note the reference's name is a lower-case #header.

Change the REGEXP to Like

SELECT * FROM table_name WHERE column_name like '%[^a-zA-Z0-9]%'

this one works fine

The simplest way to achieve this is given below,

I)

Glide.with(context.getApplicationContext())
                        .load(Your Path)   
                        .override(15, 15) // (change according to your wish)
                        .error(R.drawable.placeholder)
                        .into(image.score);

else you can follow the code below..

II)

1.Create a class.(Code is given below)

public class BlurTransformation extends BitmapTransformation {

    private RenderScript rs;

    public BlurTransformation(Context context) {
        super( context );

        rs = RenderScript.create( context );
    }

    @Override
    protected Bitmap transform(BitmapPool pool, Bitmap toTransform, int outWidth, int outHeight) {
        Bitmap blurredBitmap = toTransform.copy( Bitmap.Config.ARGB_8888, true );

        // Allocate memory for Renderscript to work with
        Allocation input = Allocation.createFromBitmap(
            rs, 
            blurredBitmap, 
            Allocation.MipmapControl.MIPMAP_FULL, 
            Allocation.USAGE_SHARED
        );
        Allocation output = Allocation.createTyped(rs, input.getType());

        // Load up an instance of the specific script that we want to use.
        ScriptIntrinsicBlur script = ScriptIntrinsicBlur.create(rs, Element.U8_4(rs));
        script.setInput(input);

        // Set the blur radius
        script.setRadius(10);

        // Start the ScriptIntrinisicBlur
        script.forEach(output);

        // Copy the output to the blurred bitmap
        output.copyTo(blurredBitmap);

        toTransform.recycle();

        return blurredBitmap;
    }

    @Override
    public String getId() {
        return "blur";
    }
}

2.Set image to ImageView using Glide.

eg:

Glide.with(this)
     .load(expertViewDetailsModel.expert.image)
     .asBitmap()
     .transform(new BlurTransformation(this))
     .into(ivBackground);

In addition to previous post you can have

<h:form rendered="#{!bean.boolvalue}" />
<h:form rendered="#{bean.textvalue == 'value'}" />

Jsf 2.0

If the user doesn't have Chrome, it will throw an exception like this:

    //chrome.exe http://xxx.xxx.xxx --incognito
    //chrome.exe http://xxx.xxx.xxx -incognito
    //chrome.exe --incognito http://xxx.xxx.xxx
    //chrome.exe -incognito http://xxx.xxx.xxx
    private static void Chrome(string link)
    {
        string url = "";

        if (!string.IsNullOrEmpty(link)) //if empty just run the browser
        {
            if (link.Contains('.')) //check if it's an url or a google search
            {
                url = link;
            }
            else
            {
                url = "https://www.google.com/search?q=" + link.Replace(" ", "+");
            }
        }

        try
        {
            Process.Start("chrome.exe", url + " --incognito");
        }
        catch (System.ComponentModel.Win32Exception e)
        {
            MessageBox.Show("Unable to find Google Chrome...",
                "chrome.exe not found!", MessageBoxButtons.OK, MessageBoxIcon.Error);
        }
    }

In view file (HTML or EJS)

<div ng-repeat="item in vm.itemList  | filter: myFilter > </div>

and In Controller

$scope.myFilter = function(item) {
return (item.propertyA === 'value' || item.propertyA === 'value');
}

By default, a vagrant box doesn't have any ip address. In order to find the IP address, you simply assign the IP address in your Vagrantfile then call vagrant reload

If you just need to access a vagrant machine from only the host machine, setting up a "private network" is all you need. Either uncomment the appropriate line in a default Vagrantfile, or add this snippet. If you want your VM to appear at 172.30.1.5 it would be the following:

config.vm.network "private_network", ip: "172.30.1.5"

Learn more about private networks. https://www.vagrantup.com/docs/networking/private_network.html

If you need vagrant to be accessible outside your host machine, for instance for developing against a mobile device such as iOS or Android, you have to enable a public network you can use either static IP, such as 192.168.1.10, or DHCP.

config.vm.network "public_network", ip: "192.168.1.10"

Learn more about configuring a public network https://www.vagrantup.com/docs/networking/public_network.html

Minor improvements to @Alex's answer that enables updating of dictionaries of differing depths as well as limiting the depth that the update dives into the original nested dictionary (but the updating dictionary depth is not limited). Only a few cases have been tested:

def update(d, u, depth=-1):
    """
    Recursively merge or update dict-like objects. 
    >>> update({'k1': {'k2': 2}}, {'k1': {'k2': {'k3': 3}}, 'k4': 4})
    {'k1': {'k2': {'k3': 3}}, 'k4': 4}
    """

    for k, v in u.iteritems():
        if isinstance(v, Mapping) and not depth == 0:
            r = update(d.get(k, {}), v, depth=max(depth - 1, -1))
            d[k] = r
        elif isinstance(d, Mapping):
            d[k] = u[k]
        else:
            d = {k: u[k]}
    return d

When you are building a new image you often want to run a new container each time and with the same name. I found the easiest way was to start the container with the --rm option:

--rm        Automatically remove the container when it exits

e.g.

docker run --name my-micro-service --rm <image>

Sadly it's used almost randomly in the examples from the docs

You can use pandas, by transforming the list to a pd.Series then simply use .value_counts()

import pandas as pd
a = ['1', '1', '1', '1', '1', '1', '2', '2', '2', '2', '7', '7', '7', '10', '10']
a_cnts = pd.Series(a).value_counts().to_dict()

Input  >> a_cnts["1"], a_cnts["10"]
Output >> (6, 2)

I was trying to download zip files linked from Omeka's themes page - pretty similar task. This worked for me:

wget -A zip -r -l 1 -nd http://omeka.org/add-ons/themes/

• -A: only accept zip files
• -r: recurse
• -l 1: one level deep (ie, only files directly linked from this page)
• -nd: don't create a directory structure, just download all the files into this directory.

All the answers with -k, -K, -E etc options probably haven't really understood the question, as those as for rewriting HTML pages to make a local structure, renaming .php files and so on. Not relevant.

To literally get all files except .html etc:

wget -R html,htm,php,asp,jsp,js,py,css -r -l 1 -nd http://yoursite.com

In order to do this in SQL Server, you must order the query by a column, so you can specify the rows you want.

Example:

select * from table order by [some_column] 
offset 10 rows
FETCH NEXT 10 rows only

I've just release a pre-alpha version of CefSharp my .Net bindings for the Chromium Embedded Framework.

Check it out and give me your thoughts: https://github.com/chillitom/CefSharp (binary libs and example available in the downloads page)

update: Released a new version, includes the ability to bind C# objects into the DOM and more.

update 2: no-longer alpha, lib is used in real world projects including Facebook Messenger for Windows, Rdio's Windows client and Github for Windows

One reason to have both is so that authentication can be done by the database server, but authorization can be scoped to the database. That way, if you move your database to another server, you can always remap the user-login relationship on the database server, but your database doesn't have to change.

Not exactly what you're looking for, but I've found this quite helpful:

git add -AN

Will add all files to the index, but without their content. Files that were untracked now behave as if they were tracked. Their content will be displayed in git diff, and you can add then interactively with git add -p.

When the WSDL is available, it is just two steps you need to follow to invoke that web service.

Step 1: Generate the client side source from a WSDL2Java tool

Step 2: Invoke the operation using:

YourService service = new YourServiceLocator();
Stub stub = service.getYourStub();
stub.operation();

If you look further, you will notice that the Stub class is used to invoke the service deployed at the remote location as a web service. When invoking that, your client actually generates the SOAP request and communicates. Similarly the web service sends the response as a SOAP. With the help of a tool like Wireshark, you can view the SOAP messages exchanged.

However since you have requested more explanation on the basics, I recommend you to refer here and write a web service with it's client to learn it further.

If you are using gcc, you can use the GNU-extension a specifier to have scanf() allocate memory for you to hold the input:

int main()
{
  char *str = NULL;

  scanf ("%as", &str);
  if (str) {
      printf("\"%s\"\n", str);
      free(str);
  }
  return 0;
}

Edit: As Jonathan pointed out, you should consult the scanf man pages as the specifier might be different (%m) and you might need to enable certain defines when compiling.

To get the column names from pandas dataframe in python3- Here I am creating a data frame from a fileName.csv file

>>> import pandas as pd
>>> df = pd.read_csv('fileName.csv')
>>> columnNames = list(df.head(0)) 
>>> print(columnNames)

Now that you have provided your HTML sample, we're able to see that your XPath is slightly wrong. While it's valid XPath, it's logically wrong.

You've got:

//*[contains(@id, 'ctl00_btnAircraftMapCell')]//*[contains(@title, 'Select Seat')]

Which translates into:

Get me all the elements that have an ID that contains ctl00_btnAircraftMapCell. Out of these elements, get any child elements that have a title that contains Select Seat.

What you actually want is:

//a[contains(@id, 'ctl00_btnAircraftMapCell') and contains(@title, 'Select Seat')]

Which translates into:

Get me all the anchor elements that have both: an id that contains ctl00_btnAircraftMapCell and a title that contains Select Seat.

For completeness, write_csv() from the readr package is faster and never writes row names

# install.packages('readr', dependencies = TRUE)
library(readr)
write_csv(t, "t.csv")

If you need to write big data out, use fwrite() from the data.table package. It's much faster than both write.csv and write_csv

# install.packages('data.table')
library(data.table)
fwrite(t, "t.csv")

Below is a benchmark that Edouard published on his site

microbenchmark(write.csv(data, "baseR_file.csv", row.names = F),
               write_csv(data, "readr_file.csv"),

I use this for cleaning up data in test/development databases. You can filter by table name and record count.

DECLARE @sqlCommand VARCHAR(3000);
DECLARE @tableList TABLE(Value NVARCHAR(128));
DECLARE @TableName VARCHAR(128);
DECLARE @RecordCount INT;

-- get a cursor with a list of table names and their record counts
DECLARE MyCursor CURSOR FAST_FORWARD
FOR SELECT t.name TableName,
           i.rows Records
    FROM sysobjects t,
         sysindexes i
    WHERE 
          t.xtype = 'U'              -- only User tables
          AND i.id = t.id          
          AND i.indid IN(0, 1)       -- 0=Heap, 1=Clustered Index
          AND i.rows < 10            -- Filter by number of records in the table
          AND t.name LIKE 'Test_%';  -- Filter tables by name. You could also provide a list:
                                     -- AND t.name IN ('MyTable1', 'MyTable2', 'MyTable3');
                                     -- or a list of tables to exclude:
                                     -- AND t.name NOT IN ('MySpecialTable', ... );

OPEN MyCursor;

FETCH NEXT FROM MyCursor INTO @TableName, @RecordCount;

-- for each table name in the cursor, delete all records from that table:
WHILE @@FETCH_STATUS = 0
    BEGIN
        SET @sqlCommand = 'DELETE FROM ' + @TableName;
        EXEC (@sqlCommand);
        FETCH NEXT FROM MyCursor INTO @TableName, @RecordCount;
    END;

CLOSE MyCursor;
DEALLOCATE MyCursor;

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

One of the most straightforward ways of gettings rid of ^Ms with just an emacs command one-liner:

    C-x h C-u M-| dos2unix    

Analysis:

    C-x h: select current buffer
    C-u: apply following command as a filter, redirecting its output to replace current buffer
    M-| dos2unix: performs `dos2unix` [current buffer]

*nix platforms have the dos2unix utility out-of-the-box, including Mac (with brew). Under Windows, it is widely available too (MSYS2, Cygwin, user-contributed, among others).

there are two cause of this exception:

1

Arrays.asList(factors) returns a List<int[]> where factors is an int array

2

you forgot to add the type parameter to:

ArrayList<Integer> f = new ArrayList(Arrays.asList(factors));

with:

ArrayList<Integer> f = new ArrayList<Integer>(Arrays.asList(factors));  

resulting in a compile-time error:

found   : java.util.List<int[]>
required: java.util.List<java.lang.Integer>

I found these instructions on a blog post that indicated this step, which worked for me (Windows 8, 64-bit):

Make sure that in windows features, you have both WCF options under .Net framework are ticked. So go to Control Panel –> Programs and Features –> Turn Windows Features ON/Off –> Features –> Add Features –> .NET Framework X.X Features. Make sure that .Net framework says it is installed, and make sure that the WCF Activation node underneath it is selected (checkbox ticked) and both options under WCF Activation are also checked.

These are:
* HTTP Activation
* Non-HTTP Activation
Both options need to be selected (checked box ticked).

You have to rely on '#' but to make the task easier in vi you can perform the following (press escape first):

:10,20 s/^/#

with 10 and 20 being the start and end line numbers of the lines you want to comment out

and to undo when you are complete:

:10,20 s/^#//

Here's my take experience with E7 async/await:

In case you have an async helperFunction() called from your test... (one explicilty with the ES7 async keyword, I mean)

? make sure, you call that as await helperFunction(whateverParams) (well, yeah, naturally, once you know...)

And for that to work (to avoid ‘await is a reserved word’), your test-function must have an outer async marker:

it('my test', async () => { ...

Another way of solving this is to use the DictReader class, which "skips" the header row and uses it to allowed named indexing.

Given "foo.csv" as follows:

FirstColumn,SecondColumn
asdf,1234
qwer,5678

Use DictReader like this:

import csv
with open('foo.csv') as f:
    reader = csv.DictReader(f, delimiter=',')
    for row in reader:
        print(row['FirstColumn'])  # Access by column header instead of column number
        print(row['SecondColumn'])

THis has helped me sooooo many times....

Here's my twist on it, with a runnable example. Note this will only work in the situation where Id is unique, and you have duplicate values in other columns.

DECLARE @SampleData AS TABLE (Id int, Duplicate varchar(20))

INSERT INTO @SampleData
SELECT 1, 'ABC' UNION ALL
SELECT 2, 'ABC' UNION ALL
SELECT 3, 'LMN' UNION ALL
SELECT 4, 'XYZ' UNION ALL
SELECT 5, 'XYZ'

DELETE FROM @SampleData WHERE Id IN (
    SELECT Id FROM (
        SELECT 
            Id
            ,ROW_NUMBER() OVER (PARTITION BY [Duplicate] ORDER BY Id) AS [ItemNumber]
            -- Change the partition columns to include the ones that make the row distinct
        FROM 
            @SampleData
    ) a WHERE ItemNumber > 1 -- Keep only the first unique item
)

SELECT * FROM @SampleData

And the results:

Id          Duplicate
----------- ---------
1           ABC
3           LMN
4           XYZ

Not sure why that's what I thought of first... definitely not the simplest way to go but it works.

<div style="float: left;margin-right:10px">
  <table>
    <tr>
      <td>..</td>
    </tr>

    <tr>
      <td>..</td>

A version that avoids creating a sub-process:

for D in *; do
    if [ -d "${D}" ]; then
        echo "${D}"   # your processing here
    fi
done

Or, if your action is a single command, this is more concise:

for D in *; do [ -d "${D}" ] && my_command; done

Or an even more concise version (thanks @enzotib). Note that in this version each value of D will have a trailing slash:

for D in */; do my_command; done

I had similar problem when importing phone number data from excel to mysql database. So a simple trick without the need to identify the length of the phone number (because the length of the phone numbers varied in my data):

UPDATE table SET phone_num = concat('0', phone_num) 

I just concated 0 in front of the phone_num.

There is the RowIndex property for the CurrentCell property for the DataGridView.

datagridview.CurrentCell.RowIndex

Handle the SelectionChanged event and find the index of the selected row as above.

I also meet this problem, and I found the solution as 2 step below: 1. In sites-enabled folder of apache2, you edit in Directory element by set "AllowOverride all" (should be "all" not "none") 2. In kohana project in www folder, rename "example.htaccess" to ".htaccess"

I did it on ubuntu. Hope that it will help you.

The syntax looks right to me ... try to change it to use INNER JOIN ...

Have a look at this.

Seems like you could also do this:

__dirname=fs.realpathSync('.');

of course, dont forget fs=require('fs')

(it's not really global in node scripts exactly, its just defined on the module level)
