TreeSet is ordered.

http://docs.oracle.com/javase/6/docs/api/java/util/TreeSet.html

Note that if you use LIKE to determine if a string is a substring of another string, you must escape the pattern matching characters in your search string.

If your SQL dialect supports CHARINDEX, it's a lot easier to use it instead:

SELECT * FROM MyTable
WHERE CHARINDEX('word1', Column1) > 0
  AND CHARINDEX('word2', Column1) > 0
  AND CHARINDEX('word3', Column1) > 0

Also, please keep in mind that this and the method in the accepted answer only cover substring matching rather than word matching. So, for example, the string 'word1word2word3' would still match.

python setup.py uses distutils which doesn't support install_requires. setuptools does, also distribute (its successor), and pip (which uses either) do. But you actually have to use them. I.e. call setuptools through the easy_install command or pip install.

Another way is to import setup from setuptools in your setup.py, but this not standard and makes everybody wanting to use your package have to have setuptools installed.

The AtomicBoolean class gives you a boolean value that you can update atomically. Use it when you have multiple threads accessing a boolean variable.

The java.util.concurrent.atomic package overview gives you a good high-level description of what the classes in this package do and when to use them. I'd also recommend the book Java Concurrency in Practice by Brian Goetz.

Mongo sends the complete document as a callbackobject so you can simply get it from there only.

for example

collection.save(function(err,room){
  var newRoomId = room._id;
  });

When we are updating/add the fragments,

Should Include the .addToBackStack().

getSupportFragmentManager().beginTransaction()
    .add(detailFragment, "detail") // Add this transaction to the back stack (name is an optional name for this back stack state, or null).
    .addToBackStack(null)
    .commit();

After that if we give the getFragments.popBackStackImmediate() will return true if we add/update the fragments, and move back to the current screen.

YOur best bet is to fix the datbase design and add the identioty column to the table. Why do you havea table without one in the first place? Especially one with duplicate records! Clearly the database itself needs redesigning.

And why do you have to have this in a view, why isn't your solution with the temp table a valid solution? Views are not usually a really good thing to do to a perfectly nice database.

Here is something I used to drop files and/or folders full of files. In my case I was filtering for *.dwg files only and chose to include all subfolders.

fileList is an IEnumerable or similar In my case was bound to a WPF control...

var fileList = (IList)FileList.ItemsSource;

See https://stackoverflow.com/a/19954958/492 for details of that trick.

The drop Handler ...

  private void FileList_OnDrop(object sender, DragEventArgs e)
  {
    var dropped = ((string[])e.Data.GetData(DataFormats.FileDrop));
    var files = dropped.ToList();

    if (!files.Any())
      return;

    foreach (string drop in dropped)
      if (Directory.Exists(drop))
        files.AddRange(Directory.GetFiles(drop, "*.dwg", SearchOption.AllDirectories));

    foreach (string file in files)
    {
      if (!fileList.Contains(file) && file.ToLower().EndsWith(".dwg"))
        fileList.Add(file);
    }
  }

public class Person
{
    // Before C# 6.0
    [Display(Name = "Age", ResourceType = typeof(Testi18n.Resource))]
    public string Age { get; set; }

    // After C# 6.0
    // [Display(Name = nameof(Resource.Age), ResourceType = typeof(Resource))]
}

1. Define ResourceType of the attribute so it looks for a resource

2. Define Name of the attribute which is used for the key of resource, after C# 6.0, you can use nameof for strong typed support instead of hard coding the key.

3. Set the culture of current thread in the controller.

Resource.Culture = CultureInfo.GetCultureInfo("zh-CN");

4. Set the accessibility of the resource to public

5. Display the label in cshtml like this

@Html.DisplayNameFor(model => model.Age)

First off, RangeToHTML. The script calls it like a method, but it isn't. It's a popular function by MVP Ron de Bruin. Coincidentally, that links points to the exact source of the script you posted, before those few lines got b?u?t?c?h?e?r?e?d? modified.

On with Range.SpecialCells. This method operates on a range and returns only those cells that match the given criteria. In your case, you seem to be only interested in the visible text cells. Importantly, it operates on a Range, not on HTML text.

For completeness sake, I'll post a working version of the script below. I'd certainly advise to disregard it and revisit the excellent original by Ron the Bruin.

           vbNewLine & "Please correct and try again.", vbOKOnly

If it's a problem with the not selector, you can set all of them and override the last one

li:after
{
  content: ' |';
}
li:last-child:after
{
  content: '';
}

or if you can use before, no need for last-child

li+li:before
{
  content: '| ';
}

If you're dealing with natural language text and need to replace a word, not just part of a string, you have to add a pinch of regular expressions to your gsub as a plain text substitution can lead to disastrous results:

'mislocated cat, vindicating'.gsub('cat', 'dog')
=> "mislodoged dog, vindidoging"

Regular expressions have word boundaries, such as \b which matches start or end of a word. Thus,

'mislocated cat, vindicating'.gsub(/\bcat\b/, 'dog')
=> "mislocated dog, vindicating"

In Ruby, unlike some other languages like Javascript, word boundaries are UTF-8-compatible, so you can use it for languages with non-Latin or extended Latin alphabets:

'???? ? ??????, ??? ??????'.gsub(/\b????\b/, '?????')
=> "????? ? ??????, ??? ??????"

This is to extend on how to process a sequence of promises in a more generic way, supporting dynamic / infinite sequences, based on spex.sequence implementation:

var $q = require("q");
var spex = require('spex')($q);

var files = []; // any dynamic source of files;

var readFile = function (file) {
    // returns a promise;
};

function source(index) {
    if (index < files.length) {
        return readFile(files[index]);
    }
}

function dest(index, data) {
    // data = resolved data from readFile;
}

spex.sequence(source, dest)
    .then(function (data) {
        // finished the sequence;
    })
    .catch(function (error) {
        // error;
    });

Not only this solution will work with sequences of any size, but you can easily add data throttling and load balancing to it.

Current best practice in CSS development is to create more general selectors with modifiers that can be applied as widely as possible throughout the web site. I would try to avoid defining separate styles for individual page elements.

If the purpose of the CSS class on the <form/> element is to control the style of elements within the form, you could add the class attribute the existing <fieldset/> element which encapsulates any form by default in web pages generated by ASP.NET MVC. A CSS class on the form is rarely necessary.

Here's my regexp pure JavaScript solution:

function highlight(text) {
    document.body.innerHTML = document.body.innerHTML.replace(
        new RegExp(text + '(?!([^<]+)?<)', 'gi'),
        '<b style="background-color:#ff0;font-size:100%">$&</b>'
    );
}

Also, does Jenkins delete the artifacts after each build ? (not the archived artifacts, I know I can tell it to delete those)

No, Hudson/Jenkins does not, by itself, clear the workspace after a build. You might have actions in your build process that erase, overwrite, or move build artifacts from where you left them. There is an option in the job configuration, in Advanced Project Options (which must be expanded), called "Clean workspace before build" that will wipe the workspace at the beginning of a new build.

You need to create a class that extends Component. There you can override the paint method and put your painting code in:

package blah.whatever;

import java.awt.Component;
import java.awt.Graphics;

public class TestAWT extends Component {

/** @see java.awt.Component#paint(java.awt.Graphics) */
@Override
public void paint(Graphics g) {
    super.paint(g);
    g.drawLine(0,0,100,100);
    g.drawLine(10, 10, 20, 300);
    // more drawing code here...
}

}

Put this component into the GUI of your application. If you're using Swing, you need to extend JComponent and override paintComponent, instead.

As Helios mentioned, the painting code actually tells the system how your component looks like. The system will ask for this information (call your painting code) when it thinks it needs to be (re)painted, for example, if a window is moved in front of your component.

When you run the code

listoflists.append((list, list[0]))

You are not (as I think you expect) adding a copy of list to the end of listoflists. What you are doing is adding a reference to list to the end of listoflists. Thus, every time you update list, it updates every reference to list, which in this case, is every item in listoflists

What you could do instead is something like this:

listoflists = []
for i in range(1, 10):
    listoflists.append((range(i), 0))

I am struggling with this problem and none of the previous answers tackle the question as I see it. I have stripped the problem back down to its basics to see if I can make my problem clear.

I create a new repository (rep1), put one file in it and commit it.

mkdir rep1
cd rep1
git init
echo "Line1" > README
git add README
git commit -m "Commit 1"

I create a clone of rep1 and call it rep2. I look inside rep2 and see the file is correct.

cd ~
git clone ~/rep1 rep2
cat ~/rep2/README

In rep1 I make a single change to the file and commit it. Then in rep1 I create a remote to point to rep2 and push the changes.

cd ~/rep1
<change file and commit>
git remote add rep2 ~/rep2
git push rep2 master

Now when I go into rep2 and do a 'git status' I get told I am ahead of origin.

# On branch master
# Your branch is ahead of 'origin/master' by 1 commit.
#
# Changes to be committed:
#   (use "git reset HEAD <file>..." to unstage)
#
#   modified:   README
#

README in rep2 is as it was originally, before the second commit. The only modifications I have done are to rep1 and all I wanted to do was push them out to rep2. What is it I am not grasping?

strip only removes characters from the beginning and end of a string. You want to use replace:

str2 = str.replace("\n", "")
re.sub('\s{2,}', ' ', str) # To remove more than one space 

I just added the oracle folder to my environmental variables and that fixed my identical error

That's an individual question that could depend on how you're working. Some people like to put the variable type at the begining of the variable, like "str_message". And some people like to use underscore between their words ("my_message") while others like to separate them with upper-case letters ("myMessage").

I'm often working with huge JavaScript libraries with other people, so functions and variables (except the private variables inside functions) got to start with the service's name to avoid conflicts, as "guestbook_message".

In short: english, lower-cased, well-organized variable and function names is preferable according to me. The names should describe their existence rather than being short.

I was facing the same issue. After many tries below solution worked for me.

Based on the answer by Fred-II I wanted to share my take on the getOS function, it avoids globals, merges both lists and detects the architecture (x32/x64)

 * @return string
 */
function getOS($user_agent = null)
{
    if(!isset($user_agent) && isset($_SERVER['HTTP_USER_AGENT'])) {
        $user_agent = $_SERVER['HTTP_USER_AGENT'];
    }

You can reference gems with source:

source: 'https://source.com', git repository (:github => 'git/url') and with local path

:path => '.../path/gem_name'.

You can learn more about [Gemfiles and how to use them] (https://kolosek.com/rails-bundle-install-and-gemfile) in this article.

in response to Dan's comment above:

I am using this method to implement the same thing, but for some reason I am getting an exception on the ReadObject method: "Expecting element 'root' from namespace ''.. Encountered 'None' with name '', namespace ''." Any ideas why? – Dan Appleyard Apr 6 '10 at 17:57

I had the same problem (MVC 3 build 3.0.11209.0), and the post below solved it for me. Basically the json serializer is trying to read a stream which is not at the beginning, so repositioning the stream to 0 'fixed' it...

http://nali.org/asp-net-mvc-expecting-element-root-from-namespace-encountered-none-with-name-namespace/

The reason that appendChild is not a function is because you're executing it on the textContent of your p element.

You instead just need to select the paragraph itself, and then append your new text node to that:

var paragraph = document.getElementById("p");_x000D_
var text = document.createTextNode("This just got added");_x000D_
_x000D_
paragraph.appendChild(text);

<p id="p">This is some text</p>

However instead, if you like, you can just modify the text itself (rather than adding a new node):

var paragraph = document.getElementById("p");_x000D_
_x000D_
paragraph.textContent += "This just got added";

<p id="p">This is some text</p>

Use

document.getElementById('<%= txt_model_code.ClientID %>')

instead of

document.getElementById('txt_model_code')`

Also you can use onClientClick instead of onClick.

^[0-9]{1,6}$ should do it. I don't know VB.NET good enough to know if it's the same there.

For examples, have a look at the Wikipedia.

As a contemporary alternative, there is a standard now for client side cryptography. This has the advantage of being optimised by the browser itself.

Taken from the example in the documentation:

async function sha256(message) {

    // encode as UTF-8
    const msgBuffer = new TextEncoder('utf-8').encode(message);

    // hash the message
    const hashBuffer = await crypto.subtle.digest('SHA-256', msgBuffer);

    // convert ArrayBuffer to Array
    const hashArray = Array.from(new Uint8Array(hashBuffer));

    // convert bytes to hex string
    const hashHex = hashArray.map(b => ('00' + b.toString(16)).slice(-2)).join('');
    return hashHex;
}

sha256('abc').then(hash => console.log(hash));

(async function() {
    const hash = await sha256('abc');
}());

MD5 is likely unsupported, however the likes of SHA-256, SHA-384, and SHA-512 are.

And those will likely be able to be calculated server side also.

Here's some documentation on usage: https://developer.mozilla.org/en-US/docs/Web/API/SubtleCrypto/digest

And cross browser compatibility: https://caniuse.com/#feat=cryptography

Also, you can use -o or --offline in the mvn command line which will put maven in "offline mode" so it won't check for updates. You'll get some warning about not being able to get dependencies not already in your local repo, but no big deal.

A StringBuilder will help you when you need to build strings in multiple steps.

Instead of doing this:

String x = "";
x += "first ";
x += "second ";
x += "third ";

you do

StringBuilder sb = new StringBuilder("");
sb.Append("first ");
sb.Append("second ");
sb.Append("third");
String x = sb.ToString();

The final effect is the same, but the StringBuilder will use less memory and will run faster. Instead of creating a new string which is the concatenation of the two, it will create the chunks separately, and only at the end it will unite them.

Just in the context of this question, I want to post the 2 'APPLY' operators as well:

JOINS:

1. INNER JOIN = JOIN

2. OUTER JOIN

   • LEFT OUTER JOIN = LEFT JOIN

   • RIGHT OUTER JOIN = RIGHT JOIN

   • FULL OUTER JOIN = FULL JOIN

3. CROSS JOIN

SELF-JOIN: This is not exactly a separate type of join. This is basically joining a table to itself using one of the above joins. But I felt it is worth mentioning in the context JOIN discussions as you will hear this term from many in the SQL Developer community.

APPLY:

1. CROSS APPLY -- Similar to INNER JOIN (But has added advantage of being able to compute something in the Right table for each row of the Left table and would return only the matching rows)
2. OUTER APPLY -- Similar to LEFT OUTER JOIN (But has added advantage of being able to compute something in the Right table for each row of the Left table and would return all the rows from the Left table irrespective of a match on the Right table)

https://www.mssqltips.com/sqlservertip/1958/sql-server-cross-apply-and-outer-apply/

https://sqlhints.com/2016/10/23/outer-apply-in-sql-server/

Real life example, when to use OUTER / CROSS APPLY in SQL

I find APPLY operator very beneficial as they give better performance than having to do the same computation in a subquery. They are also replacement of many Analytical functions in older versions of SQL Server. That is why I believe that after being comfortable with JOINS, one SQL developer should try to learn the APPLY operators next.

• Linear regression output as probabilities

  It's tempting to use the linear regression output as probabilities but it's a mistake because the output can be negative, and greater than 1 whereas probability can not. As regression might actually produce probabilities that could be less than 0, or even bigger than 1, logistic regression was introduced.

  Source: http://gerardnico.com/wiki/data_mining/simple_logistic_regression

  

• Outcome

  In linear regression, the outcome (dependent variable) is continuous. It can have any one of an infinite number of possible values.

  In logistic regression, the outcome (dependent variable) has only a limited number of possible values.

• The dependent variable

  Logistic regression is used when the response variable is categorical in nature. For instance, yes/no, true/false, red/green/blue, 1st/2nd/3rd/4th, etc.

  Linear regression is used when your response variable is continuous. For instance, weight, height, number of hours, etc.

• Equation

  Linear regression gives an equation which is of the form Y = mX + C, means equation with degree 1.

  However, logistic regression gives an equation which is of the form Y = e^X + e^-X

• Coefficient interpretation

  In linear regression, the coefficient interpretation of independent variables are quite straightforward (i.e. holding all other variables constant, with a unit increase in this variable, the dependent variable is expected to increase/decrease by xxx).

  However, in logistic regression, depends on the family (binomial, Poisson, etc.) and link (log, logit, inverse-log, etc.) you use, the interpretation is different.

• Error minimization technique

  Linear regression uses ordinary least squares method to minimise the errors and arrive at a best possible fit, while logistic regression uses maximum likelihood method to arrive at the solution.

  Linear regression is usually solved by minimizing the least squares error of the model to the data, therefore large errors are penalized quadratically.

  Logistic regression is just the opposite. Using the logistic loss function causes large errors to be penalized to an asymptotically constant.

  Consider linear regression on categorical {0, 1} outcomes to see why this is a problem. If your model predicts the outcome is 38, when the truth is 1, you've lost nothing. Linear regression would try to reduce that 38, logistic wouldn't (as much)².

I solved this question with solution below

  import org.joda.time.LocalDate;
  Date myDate = new Date();
  LocalDate localDate = LocalDate.fromDateFields(myDate);
  System.out.println("My date using Date" Nov 18 11:23:33 BRST 2016);
  System.out.println("My date using joda.time LocalTime" 2016-11-18);

In this case localDate print your date in this format "yyyy-MM-dd"

A better way to clear the screen from within a script...

If you're using the OS X Terminal app (as stated by the OP), a better approach (thanks to Chris Page's answer to How do I reset the scrollback in the terminal via a shell command?) is just this:

clear && printf '\e[3J'

or more concisely (hat tip to user qiuyi):

printf '\33c\e[3J'

which clears the scrollback buffer as well as the screen. There are other options as well. See Chris Page's answer to How do I reset the scrollback in the terminal via a shell command? for more information.

Original answer

The AppleScript answer given in this thread works, but it has the nasty side effect of clearing any terminal window that happens to be active. This is surprising if you're running the script in one window and trying to get work done in another!

You avoid this by refining the AppleScript to only clear the screen if it is frontmost by doing this (taken from MattiSG's answer to How do I reset the scrollback in the terminal via a shell command?):

osascript -e 'if application "Terminal" is frontmost then tell application "System Events" to keystroke "k" using command down'

... but as when it's not the current window, the output will stack up until it becomes current again, which probably isn't what you want.

What you are getting is the result of the toString() method of the Object class or, more precisely, the identityHashCode() as uzay95 has pointed out.

"When we create an object in java with new keyword, we are getting a memory address from the OS."

It is important to realize that everything you do in Java is handled by the Java Virtual Machine. It is the JVM that is giving this information. What actually happens in the RAM of the host operating system depends entirely on the implementation of the JRE.

A slightly changed version from the one mantish posted:

var regExp = /^.*(youtu.be\/|v\/|u\/\w\/|embed\/|watch\?v=|\&v=)([^#\&\?]{11,11}).*/;
var match = url.match(regExp);
if (match) if (match.length >= 2) return match[2];
// error

This assumes the code is always 11 characters. I'm using this in ActionScript, not sure if {11,11} is supported in Javascript. Also added support for &v=.... (just in case)

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

The standard numpy function for what you want is np.column_stack:

>>> np.column_stack(([1, 2, 3], [4, 5, 6]))
array([[1, 4],
       [2, 5],
       [3, 6]])

So with your portfolio and index arrays, doing

np.column_stack((portfolio, index))

would yield something like:

[[portfolio_value1, index_value1],
 [portfolio_value2, index_value2],
 [portfolio_value3, index_value3],
 ...]

You can use the getimagesize function like this:

list($width, $height) = getimagesize('path to image');
echo "width: " . $width . "<br />";
echo "height: " .  $height;

Hi I have been using this page a lot for constraints and "how to". It took me forever to get to the point of realizing I needed:

myView.translatesAutoresizingMaskIntoConstraints = NO;

to get this example to work. Thank you Userxxx, Rob M. and especially larsacus for the explanation and code here, it has been invaluable.

Here is the code in full to get the examples above to run:

UIView *myView = [[UIView alloc] init];
myView.backgroundColor = [UIColor redColor];
myView.translatesAutoresizingMaskIntoConstraints = NO;  //This part hung me up 
[self.view addSubview:myView];
//needed to make smaller for iPhone 4 dev here, so >=200 instead of 748
[self.view addConstraints:[NSLayoutConstraint
                           constraintsWithVisualFormat:@"V:|-[myView(>=200)]-|"
                           options:NSLayoutFormatDirectionLeadingToTrailing
                           metrics:nil
                           views:NSDictionaryOfVariableBindings(myView)]];

[self.view addConstraints:[NSLayoutConstraint
                           constraintsWithVisualFormat:@"H:[myView(==200)]-|"
                           options:NSLayoutFormatDirectionLeadingToTrailing
                           metrics:nil
                           views:NSDictionaryOfVariableBindings(myView)]];

Variables can be assigned but not declared inside the conditional statement:

int v;
if((v = someMethod()) != 0) return true;

Even better

#include <stdio.h>
int
main(void)
{
  char *line = NULL;
  size_t count;
  char *dup_line;

  getline(&line,&count, stdin);
  dup_line=strdup(line);

  puts(dup_line);

  free(dup_line);
  free(line);

  return 0;
}

From the accepted answer, it looks like your desired behaviour is to turn

skip 0
skip 1
skip 2
skip 3

If that's right, then I think something like

import csv

with open("test.dat", "rb") as infile, open("test.csv", "wb") as outfile:
    reader = csv.reader(infile)
    writer = csv.writer(outfile, quoting=False)
    for i, line in enumerate(reader):
        if i < 4: continue
        date = line[0].split()
        day = date[0].split('-')
        time = date[1].split(':')
        newline = day + time + line[1:]
        writer.writerow(newline)

would be a little simpler than the reps stuff.

A way to use this in react:

class Timeout extends Component {
  constructor(props){
    super(props)

    this.state = {
      timeout: null
    }

  }

  userTimeout(){
    const { timeout } = this.state;
    clearTimeout(timeout);
    this.setState({
      timeout: setTimeout(() => {this.callAPI()}, 250)
    })

  }
}

Helpful if you'd like to only call an API after the user has stopped typing for instance. The userTimeout function could be bound via onKeyUp to an input.

Through GNU awk,

$ echo "Here is a string" | awk -v FS="(Here|string)" '{print $2}'
 is a 

grep with -P(perl-regexp) parameter supports \K, which helps in discarding the previously matched characters. In our case , the previously matched string was Here so it got discarded from the final output.

$ echo "Here is a string" | grep -oP 'Here\K.*(?=string)'
 is a 
$ echo "Here is a string" | grep -oP 'Here\K(?:(?!string).)*'
 is a 

If you want the output to be is a then you could try the below,

$ echo "Here is a string" | grep -oP 'Here\s*\K.*(?=\s+string)'
is a
$ echo "Here is a string" | grep -oP 'Here\s*\K(?:(?!\s+string).)*'
is a

The mysql command line is prone to too many problems on import. Here is how you do it:

• use excel to edit the header names to have no spaces
• save as .csv
• use free Navicat Lite Sql Browser to import and auto create a new table (give it a name)
• open the new table insert a primary auto number column for ID
• change the type of the columns as desired.
• done!

As it is already explained in other answers, const in C merely means that a variable is read-only. It is still a run-time value. However, you can use an enum as a real constant in C:

enum { NUM_TYPES = 4 };
static int types[NUM_TYPES] = { 
  1, 2, 3, 4
};

The most straightforward way to list all tables at command line is, for my taste :

psql -a -U <user> -p <port> -h <server> -c "\dt"

For a given database just add the database name :

psql -a -U <user> -p <port> -h <server> -c "\dt" <database_name>

It works on both Linux and Windows.

If you have a menu then changing ShortcutKeys property of the ToolStripMenuItem should do the trick.

If not, you could create one and set its visible property to false.

I was facing this issue for long time. Finally it was issue of ssh-add. Git ssh credentials were not taken into consideration.

Check following command might work for you:

ssh-add

Just simply add or die(mysqli_error($db)); at the end of your query, this will print the mysqli error.

 mysqli_query($db,"INSERT INTO stockdetails (`itemdescription`,`itemnumber`,`sellerid`,`purchasedate`,`otherinfo`,`numberofitems`,`isitdelivered`,`price`) VALUES ('$itemdescription','$itemnumber','$sellerid','$purchasedate','$otherinfo','$numberofitems','$numberofitemsused','$isitdelivered','$price')") or die(mysqli_error($db));

As a side note I'd say you are at risk of mysql injection, check here How can I prevent SQL injection in PHP?. You should really use prepared statements to avoid any risk.

IN completion to above answers, you can also customize your fallbacks for each async call you do, so that each call to the generic ASYNC method will populate different data, depending on the onTaskDone stuff you put there.

  Main.FragmentCallback FC= new  Main.FragmentCallback(){
            @Override
            public void onTaskDone(String results) {

                localText.setText(results); //example TextView
            }
        };

new API_CALL(this.getApplicationContext(), "GET",FC).execute("&Books=" + Main.Books + "&args=" + profile_id);

Remind: I used interface on the main activity thats where "Main" comes, like this:

public interface FragmentCallback {
    public void onTaskDone(String results);


}

My API post execute looks like this:

  @Override
    protected void onPostExecute(String results) {

        Log.i("TASK Result", results);
        mFragmentCallback.onTaskDone(results);

    }

The API constructor looks like this:

 class  API_CALL extends AsyncTask<String,Void,String>  {

    private Main.FragmentCallback mFragmentCallback;
    private Context act;
    private String method;


    public API_CALL(Context ctx, String api_method,Main.FragmentCallback fragmentCallback) {
        act=ctx;
        method=api_method;
        mFragmentCallback = fragmentCallback;


    }

For versions higher than 6.8 (7.x) you need two things.

1. change the network host to listen on the public interface.

In the configuration file elasticsearch.yml (for debian and derivatives -> /etc/elasticsearch/elasticsearch.yml).

• set the network.host or network.bind_host to:

...
network.host: 0.0.0.0
...

Or the interface that must be reached

2. Before going to production it's necessary to set important discovery and cluster formation settings.

According to elastic.co:
v6.8 -> discovery settings that should set.
by e.g

...
# roughly means the same as 1
discovery.zen.minimum_master_nodes: -1
...

v7.x -> discovery settings that should set.
by one single node

discovery.type: single-node
#OR set discovery.seed_hosts : 127.0.0.1:9200

at least one of [discovery.seed_hosts, discovery.seed_providers, cluster.initial_master_nodes] must be configured.

You can use the split command with the -b option:

split -b 1024m file.tar.gz

It can be reassembled on a Windows machine using @Joshua's answer.

copy /b file1 + file2 + file3 + file4 filetogether

Edit: As @Charlie stated in the comment below, you might want to set a prefix explicitly because it will use x otherwise, which can be confusing.

split -b 1024m "file.tar.gz" "file.tar.gz.part-"

// Creates files: file.tar.gz.part-aa, file.tar.gz.part-ab, file.tar.gz.part-ac, ...

Edit: Editing the post because question is closed and the most effective solution is very close to the content of this answer:

# create archives
$ tar cz my_large_file_1 my_large_file_2 | split -b 1024MiB - myfiles_split.tgz_
# uncompress
$ cat myfiles_split.tgz_* | tar xz

This solution avoids the need to use an intermediate large file when (de)compressing. Use the tar -C option to use a different directory for the resulting files. btw if the archive consists from only a single file, tar could be avoided and only gzip used:

# create archives
$ gzip -c my_large_file | split -b 1024MiB - myfile_split.gz_
# uncompress
$ cat myfile_split.gz_* | gunzip -c > my_large_file

For windows you can download ported versions of the same commands or use cygwin.

So you want to create a list of lists... We need to start with an empty list

list_of_lists = []

next, we read the file content, line by line

with open('data') as f:
    for line in f:
        inner_list = [elt.strip() for elt in line.split(',')]
        # in alternative, if you need to use the file content as numbers
        # inner_list = [int(elt.strip()) for elt in line.split(',')]
        list_of_lists.append(inner_list)

A common use case is that of columnar data, but our units of storage are the rows of the file, that we have read one by one, so you may want to transpose your list of lists. This can be done with the following idiom

by_cols = zip(*list_of_lists)

Another common use is to give a name to each column

col_names = ('apples sold', 'pears sold', 'apples revenue', 'pears revenue')
by_names = {}
for i, col_name in enumerate(col_names):
    by_names[col_name] = by_cols[i]

so that you can operate on homogeneous data items

 mean_apple_prices = [money/fruits for money, fruits in
                     zip(by_names['apples revenue'], by_names['apples_sold'])]

Most of what I've written can be speeded up using the csv module, from the standard library. Another third party module is pandas, that lets you automate most aspects of a typical data analysis (but has a number of dependencies).

Update While in Python 2 zip(*list_of_lists) returns a different (transposed) list of lists, in Python 3 the situation has changed and zip(*list_of_lists) returns a zip object that is not subscriptable.

If you need indexed access you can use

by_cols = list(zip(*list_of_lists))

that gives you a list of lists in both versions of Python.

On the other hand, if you don't need indexed access and what you want is just to build a dictionary indexed by column names, a zip object is just fine...

file = open('some_data.csv')
names = get_names(next(file))
columns = zip(*((x.strip() for x in line.split(',')) for line in file)))
d = {}
for name, column in zip(names, columns): d[name] = column

Since my account is new I can't up-vote Nino van Hooff's answer. If your strings are coming from a Windows based source such as an aspx based server, this solution does work:

rawText.replaceAll("(\\\\r\\\\n|\\\\n)", "<br />");

Seems to be a weird character set issue as the double back-slashes are being interpreted as single slash escape characters. Hence the need for the quadruple slashes above.

Again, under most circumstances "(\\r\\n|\\n)" should work, but if your strings are coming from a Windows based source try the above.

Just an FYI tried everything to correct the issue I was having replacing those line endings. Thought at first was failed conversion from Windows-1252 to UTF-8. But that didn't working either. This solution is what finally did the trick. :)

Only using Session.Clear() when a user logs out can pose a security hole. As the session is still valid as far as the Web Server is concerned. It is then a reasonably trivial matter to sniff, and grab the session Id, and hijack that session.

For this reason, when logging a user out it would be safer and more sensible to use Session.Abandon() so that the session is destroyed, and a new session created (even though the logout UI page would be part of the new session, the new session would not have any of the users details in it and hijacking the new session would be equivalent to having a fresh session, hence it would be mute).

Here's a variation of Eli Holmes' answer that worked for me without using latex:

Text<span id="a1">[¹](#1)</span>

<span id="1">¹</span> Footnote.[?](#a1)<br>

Example

try:

Cursor  cursor = db.rawQuery("select * from table",null);

AND for List<String>:

if (cursor.moveToFirst()) {
  while (!cursor.isAfterLast()) {
    String name = cursor.getString(cursor.getColumnIndex(countyname));

    list.add(name);
    cursor.moveToNext();
  }
}

git-gui gives a good answer: a previous git has crashed and left a lock file. Manually remove. In my case, this was in .git/ref/heads/branchname.lock.

delete, and error 128 goes away. It surprises that tortoisegit doesn't give such an easy explanation.

First step to get The Library: Open terminal and execute pip install mysql-python-connector. After the installation go the second step.

Second Step to import the library: Open your python file and write the following code: import mysql.connector

Third step to connect to the server: Write the following code:

conn = mysql.connector.connect(host=you host name like localhost or 127.0.0.1, username=your username like root, password = your password)

Third step Making the cursor: Making a cursor makes it easy for us to run queries. To make the cursor use the following code: cursor = conn.cursor()

Executing queries: For executing queries you can do the following: cursor.execute(query)

If the query changes any thing in the table you need to add the following code after the execution of the query: conn.commit()

Getting values from a query: If you want to get values from a query then you can do the following: cursor.excecute('SELECT * FROM table_name') for i in cursor: print(i) #Or for i in cursor.fetchall(): print(i)

The fetchall() method returns a list with many tuples that contain the values that you requested ,row after row .

Closing the connection: To close the connection you should use the following code: conn.close()

Handling exception: To Handel exception you can do it Vai the following method: try: #Logic pass except mysql.connector.errors.Error: #Logic pass To use a database: For example you are a account creating system where you are storing the data in a database named blabla, you can just add a database parameter to the connect() method ,like

mysql.connector.connect(database = database name)

don't remove other informations like host,username,password.

This isn't possible with ruby currently. You can't pass 'empty' attributes to methods. The closest you can get is to pass nil:

ldap_get(base_dn, filter, nil, X)

However, this will set the scope to nil, not LDAP::LDAP_SCOPE_SUBTREE.

What you can do is set the default value within your method:

def ldap_get(base_dn, filter, scope = nil, attrs = nil)
  scope ||= LDAP::LDAP_SCOPE_SUBTREE
  ... do something ...
end

Now if you call the method as above, the behaviour will be as you expect.

$date = '2014-02-25';
date('D', strtotime($date));

try this

var  insert = DateTime.ParseExact(line[i], "M/d/yyyy h:mm", CultureInfo.InvariantCulture);

Noone cand read the file except for those who have access to the file. You must make the code readable (but not writable) by the web server. If the php code handler is running properly you can't read it by requesting by name from the web server.

If someone compromises your server you are at risk. Ensure that the web server can only write to locations it absolutely needs to. There are a few locations under /var which should be properly configured by your distribution. They should not be accessible over the web. /var/www should not be writable, but may contain subdirectories written to by the web server for dynamic content. Code handlers should be disabled for these.

Ensure you don't do anything in your php code which can lead to code injection. The other risk is directory traversal using paths containing .. or begining with /. Apache should already be patched to prevent this when it is handling paths. However, when it runs code, including php, it does not control the paths. Avoid anything that allows the web client to pass a file path.

1. declarations: This property tells about the Components, Directives and Pipes that belong to this module.
2. exports: The subset of declarations that should be visible and usable in the component templates of other NgModules.
3. imports: Other modules whose exported classes are needed by component templates declared in this NgModule.
4. providers: Creators of services that this NgModule contributes to the global collection of services; they become accessible in all parts of the app. (You can also specify providers at the component level, which is often preferred.)
5. bootstrap: The main application view, called the root component, which hosts all other app views. Only the root NgModule should set the bootstrap property.

To make a simple hexagon without the need for a loop, Just use the beginPath() function. Make sure your canvas.getContext('2d') is the equal to ctx if not it will not work.

I also like to add a variable called times that I can use to scale the object if I need to.This what I don't need to change each number.

     // Times Variable 

     var times = 1;

    // Create a shape

    ctx.beginPath();
    ctx.moveTo(99*times, 0*times);
    ctx.lineTo(99*times, 0*times);
    ctx.lineTo(198*times, 50*times);
    ctx.lineTo(198*times, 148*times);
    ctx.lineTo(99*times, 198*times);
    ctx.lineTo(99*times, 198*times);
    ctx.lineTo(1*times, 148*times);
    ctx.lineTo(1*times,57*times);
    ctx.closePath();
    ctx.clip();
    ctx.stroke();

Detailed Solution with Screenshots

1. Create an empty user interface file and name it MyCustomCell.xib.

2. Add a UITableViewCell as the root of your xib file and any other visual components you want.

3. Create a cocoa touch class file with class name MyCustomCell as a subclass of UITableViewCell.

4. Set the custom class and reuse identifier for your custom table view cell.

5. Open the assistant editor and ctrl+drag to create outlets for your visual components.

6. Configure a UIViewController to use your custom cell.

class MyViewController: UIViewController {

    @IBOutlet weak var myTable: UITableView!

    override func viewDidLoad {
        super.viewDidLoad()

        let nib = UINib(nibName: "MyCustomCell", bundle: nil)
        myTable.register(nib, forCellReuseIdentifier: "MyCustomCell")
        myTable.dataSource = self
    }

    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        if let cell = tableView.dequeueReusableCell(withIdentifier: "MyCustomCell") as? MyCustomCell {
            cell.myLabel.text = "Hello world."
            return cell
        }
        ...
    }
}

The following steps work fine on macOS Sierra 10.12.4. Note that after brew installs Docker, the docker command (symbolic link) is not available at /usr/local/bin. Running the Docker app for the first time creates this symbolic link. See the detailed steps below.

1. Install Docker.

   brew cask install docker
   

2. Launch Docker.

   • Press ? + Space to bring up Spotlight Search and enter Docker to launch Docker.
   • In the Docker needs privileged access dialog box, click OK.
   • Enter password and click OK.

   When Docker is launched in this manner, a Docker whale icon appears in the status menu. As soon as the whale icon appears, the symbolic links for docker, docker-compose, docker-credential-osxkeychain and docker-machine are created in /usr/local/bin.

   $ ls -l /usr/local/bin/docker*
   lrwxr-xr-x  1 susam  domain Users  67 Apr 12 14:14 /usr/local/bin/docker -> /Users/susam/Library/Group Containers/group.com.docker/bin/docker
   lrwxr-xr-x  1 susam  domain Users  75 Apr 12 14:14 /usr/local/bin/docker-compose -> /Users/susam/Library/Group Containers/group.com.docker/bin/docker-compose
   lrwxr-xr-x  1 susam  domain Users  90 Apr 12 14:14 /usr/local/bin/docker-credential-osxkeychain -> /Users/susam/Library/Group Containers/group.com.docker/bin/docker-credential-osxkeychain
   lrwxr-xr-x  1 susam  domain Users  75 Apr 12 14:14 /usr/local/bin/docker-machine -> /Users/susam/Library/Group Containers/group.com.docker/bin/docker-machine
   

3. Click on the docker whale icon in the status menu and wait for it to show Docker is running.

   

4. Test that docker works fine.

   $ docker run hello-world
   Unable to find image 'hello-world:latest' locally
   latest: Pulling from library/hello-world
   78445dd45222: Pull complete
   Digest: sha256:c5515758d4c5e1e838e9cd307f6c6a0d620b5e07e6f927b07d05f6d12a1ac8d7
   Status: Downloaded newer image for hello-world:latest
   
   Hello from Docker!
   This message shows that your installation appears to be working correctly.
   
   To generate this message, Docker took the following steps:
    1. The Docker client contacted the Docker daemon.
    2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
    3. The Docker daemon created a new container from that image which runs the
       executable that produces the output you are currently reading.
    4. The Docker daemon streamed that output to the Docker client, which sent it
       to your terminal.
   
   To try something more ambitious, you can run an Ubuntu container with:
    $ docker run -it ubuntu bash

5. If you are going to use docker-machine to create virtual machines, install VirtualBox.

   brew cask install virtualbox
   

   Note that if VirtualBox is not installed, then docker-machine fails with the following error.

   $ docker-machine create manager
   Running pre-create checks...
   Error with pre-create check: "VBoxManage not found. Make sure VirtualBox is installed and VBoxManage is in the path"
   

Its not very elegant but in case you cant change the creation of dictionary, and all you need is a dirty hack, how about this:

var item = MyDictionary.Where(x => x.Key.ToLower() == MyIndex.ToLower()).FirstOrDefault();
    if (item != null)
    {
        TheValue = item.Value;
    }

Eclipse uses the default Java on the system to run itself. This can also be changed in the eclipse.ini file in your eclipse install folder.

To find out the version of java that your eclipse project is using, see Project->properties->build path->Libraries tab and see the JRE system library thats being used. You can also check it out at Window->Preferences->Java->Installed JREs. This is a list of all JREs that eclipse knows about

To find out using code, use the System.getProperty(...) method. See http://java.sun.com/j2se/1.5.0/docs/api/java/lang/System.html#getProperties() for supported properties.

Using Jupyterthemes, one can easily change look of notebook.

pip install jupyterthemes

jt -fs 15 

By default code font size is set to 11 . Trying above will change font size. It can be reset using.

jt -r 

This will reset all jupyter theme changes to default.

This is probably old news by now, but the magic seems to be:

• [ScriptService] attribute on web service class
• [ScriptMethod(UseHttpGet = true, ResponseFormat = ResponseFormat.Json)] on method
• Content-type: application/json in request

With those pieces in place, a GET request is successful.

For a HTTP POST

• [ScriptMethod(UseHttpGet = false, ResponseFormat = ResponseFormat.Json)] on method

and on the client side (assuming your webmethod is called MethodName, and it takes a single parameter called searchString):

        $.ajax({
            url: "MyWebService.asmx/MethodName",
            type: "POST",
            contentType: "application/json",
            data: JSON.stringify({ searchString: q }),
            success: function (response) {                  
            },
            error: function (jqXHR, textStatus, errorThrown) {
                alert(textStatus + ": " + jqXHR.responseText);
            }
        });

Use SimpleDateFormat for Android N and above. Use the calendar for earlier versions for example:

if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
        fileName = new SimpleDateFormat("yyyy-MM-dd-hh:mm:ss").format(new Date());
        Log.i("fileName before",fileName);
    }else{
        Calendar cal = Calendar.getInstance();
        cal.add(Calendar.MONTH,1);
        String zamanl =""+cal.get(Calendar.YEAR)+"-"+cal.get(Calendar.MONTH)+"-"+cal.get(Calendar.DAY_OF_MONTH)+"-"+cal.get(Calendar.HOUR_OF_DAY)+":"+cal.get(Calendar.MINUTE)+":"+cal.get(Calendar.SECOND);

        fileName= zamanl;
        Log.i("fileName after",fileName);
    }

Output:
fileName before: 2019-04-12-07:14:47  // use SimpleDateFormat
fileName after: 2019-4-12-7:13:12        // use Calender

Complete solution for mysql current month and current year, which makes use of indexing properly as well :)

-- Current month
SELECT id, timestampfield 
  FROM table1
 WHERE timestampfield >= DATE_SUB(CURRENT_DATE, INTERVAL DAYOFMONTH(CURRENT_DATE)-1 DAY)
   AND timestampfield <=  LAST_DAY(CURRENT_DATE);

-- Current year
SELECT id, timestampfield 
  FROM table1
 WHERE timestampfield >= DATE_SUB(CURRENT_DATE, INTERVAL DAYOFYEAR(CURRENT_DATE)-1 DAY)
   AND timestampfield <=  LAST_DAY(CURRENT_DATE);

What's likely happening is that SignalData is indirectly changing the subscribers dictionary under the hood during the loop and leading to that message. You can verify this by changing

foreach(Subscriber s in subscribers.Values)

To

foreach(Subscriber s in subscribers.Values.ToList())

If I'm right, the problem will disappear.

Calling subscribers.Values.ToList() copies the values of subscribers.Values to a separate list at the start of the foreach. Nothing else has access to this list (it doesn't even have a variable name!), so nothing can modify it inside the loop.

I think the easiest is to simply open the file in write mode and then close it. For example, if your file myfile.dat contains:

"This is the original content"

Then you can simply write:

f = open('myfile.dat', 'w')
f.close()

This would erase all the content. Then you can write the new content to the file:

f = open('myfile.dat', 'w')
f.write('This is the new content!')
f.close()

Your issue is in PHPMyAdmin itself. Some versions do not display the value of bit columns, even though you did set it correctly.

You maybe wanted to do the following:

foreach($user->data as $mydata)

    {
         echo $mydata->name . "\n";
         foreach($mydata->values as $values)
         {
              echo $values->value . "\n";
         }
    }        

useState is a hook that lets you add state to a functional component. It accepts an argument which is the initial value of the state property and returns the current value of state property and a method which is capable of updating that state property.
Following is a simple example:

import React, {useState} from react    

function HookCounter {    
  const [count, stateCount]= useState(0)    
    return(    
      <div>     
        <button onClick{( ) => setCount(count+1)}> count{count}</button>    
      </div>    
    )   
 }

useState accepts the initial value of the state variable which is zero in this case and returns a pair of values. The current value of the state has been called count and a method that can update the state variable has been called as setCount.

This is my understanding of what the relations are between the various "urllibs":

In the Python 2 standard library there exist two HTTP libraries side-by-side. Despite the similar name, they are unrelated: they have a different design and a different implementation.

• urllib was the original Python HTTP client, added to the standard library in Python 1.2.
• urllib2 was a more capable HTTP library, added in Python 1.6, intended to be eventually a replacement for urllib.

The Python 3 standard library has a new urllib, that is a merged/refactored/rewritten version of those two packages.

urllib3 is a third-party package. Despite the name, it is unrelated to the standard library packages, and there is no intention to include it in the standard library in the future.

Finally, requests internally uses urllib3, but it aims for an easier-to-use API.

This issue can be resolved permanently by running 1. systemctl enable docker 2. service docker start

I believe this would be somewhere close.

INSERT INTO Files
(FileId, FileData)
SELECT 1, * FROM OPENROWSET(BULK N'C:\Image.jpg', SINGLE_BLOB) rs

Something to note, the above runs in SQL Server 2005 and SQL Server 2008 with the data type as varbinary(max). It was not tested with image as data type.

To get the index values as a list/list of tuples for Index/MultiIndex do:

df.index.values.tolist()  # an ndarray method, you probably shouldn't depend on this

or

list(df.index.values)  # this will always work in pandas

There's a plugin for Notepad++ called XML Tools that offers XML verification and validation against an XSD.

You can see how to use it here.

That very well may be a false positive. Like the warning message says, it is common for a capture to start in the middle of a tcp session. In those cases it does not have that information. If you are really missing acks then it is time to start looking upstream from your host for where they are disappearing. It is possible that tshark can not keep up with the data and so it is dropping some metrics. At the end of your capture it will tell you if the "kernel dropped packet" and how many. By default tshark disables dns lookup, tcpdump does not. If you use tcpdump you need to pass in the "-n" switch. If you are having a disk IO issue then you can do something like write to memory /dev/shm. BUT be careful because if your captures get very large then you can cause your machine to start swapping.

My bet is that you have some very long running tcp sessions and when you start your capture you are simply missing some parts of the tcp session due to that. Having said that, here are some of the things that I have seen cause duplicate/missing acks.

1. Switches - (very unlikely but sometimes they get in a sick state)
2. Routers - more likely than switches, but not much
3. Firewall - More likely than routers. Things to look for here are resource exhaustion (license, cpu, etc)
4. Client side filtering software - antivirus, malware detection etc.

As for me, curly braces serve as a substitution for concatenation, they are quicker to type and code looks cleaner. Remember to use double quotes (" ") as their content is parsed by PHP, because in single quotes (' ') you'll get the literal name of variable provided:

<?php

 $a = '12345';

// This works:
 echo "qwe{$a}rty"; // qwe12345rty, using braces
 echo "qwe" . $a . "rty"; // qwe12345rty, concatenation used

// Does not work:
 echo 'qwe{$a}rty'; // qwe{$a}rty, single quotes are not parsed
 echo "qwe$arty"; // qwe, because $a became $arty, which is undefined

?>

Using standard C++ calling (note that you should use namespace std for cout or add using namespace std;)

#include <iostream>

int main()
{
    std::cout<<"Hello World!\n";
    return 0;
}

#include <stdio.h>
#include <stdlib.h>

int main(int argc, char **argv) {
  int i, parameter = 0;
  if (argc >= 2) {
    /* there is 1 parameter (or more) in the command line used */
    /* argv[0] may point to the program name */
    /* argv[1] points to the 1st parameter */
    /* argv[argc] is NULL */
    parameter = atoi(argv[1]); /* better to use strtol */
    if (parameter > 0) {
      for (i = 0; i < parameter; i++) printf("%d ", i);
    } else {
      fprintf(stderr, "Please use a positive integer.\n");
    }
  }
  return 0;
}

If you want to use them like that, define the function with the variable names as normal:

def my_function(school, standard, city, name):
    schoolName  = school
    cityName = city
    standardName = standard
    studentName = name

Now you can use ** when you call the function:

data = {'school':'DAV', 'standard': '7', 'name': 'abc', 'city': 'delhi'}

my_function(**data)

and it will work as you want.

P.S. Don't use reserved words such as class.(e.g., use klass instead)

As of CMake 3.1+ the developers strongly discourage users from using file(GLOB or file(GLOB_RECURSE to collect lists of source files.

Note: We do not recommend using GLOB to collect a list of source files from your source tree. If no CMakeLists.txt file changes when a source is added or removed then the generated build system cannot know when to ask CMake to regenerate. The CONFIGURE_DEPENDS flag may not work reliably on all generators, or if a new generator is added in the future that cannot support it, projects using it will be stuck. Even if CONFIGURE_DEPENDS works reliably, there is still a cost to perform the check on every rebuild.

See the documentation here.

There are two goods answers ([1], [2]) here on SO detailing the reasons to manually list source files.

It is possible. E.g. with file(GLOB:

cmake_minimum_required(VERSION 2.8)

file(GLOB helloworld_SRC
     "*.h"
     "*.cpp"
)

add_executable(helloworld ${helloworld_SRC})

Note that this requires manual re-running of cmake if a source file is added or removed, since the generated build system does not know when to ask CMake to regenerate, and doing it at every build would increase the build time.

As of CMake 3.12, you can pass the CONFIGURE_DEPENDS flag to file(GLOB to automatically check and reset the file lists any time the build is invoked. You would write:

cmake_minimum_required(VERSION 3.12)

file(GLOB helloworld_SRC CONFIGURE_DEPENDS "*.h" "*.cpp")

This at least lets you avoid manually re-running CMake every time a file is added.

There's an ongoing effort for a PDCurses port:

http://www.mail-archive.com/[email protected]/msg00129.html

http://www.projectpluto.com/win32a.htm

C++20 will have "uniform container erasure", and you'll be able to write:

std::erase_if(numbers, [](int n){ return n % 2 == 0 });

And that will work for vector, set, deque, etc. See cppReference for more info.

This is called a correlated update

UPDATE table1 t1
   SET (name, desc) = (SELECT t2.name, t2.desc
                         FROM table2 t2
                        WHERE t1.id = t2.id)
 WHERE EXISTS (
    SELECT 1
      FROM table2 t2
     WHERE t1.id = t2.id )

Assuming the join results in a key-preserved view, you could also

UPDATE (SELECT t1.id, 
               t1.name name1,
               t1.desc desc1,
               t2.name name2,
               t2.desc desc2
          FROM table1 t1,
               table2 t2
         WHERE t1.id = t2.id)
   SET name1 = name2,
       desc1 = desc2

if your question is "how to bind events on ajax loaded content" you can do like this :

$("img.lazy").lazyload({
    effect : "fadeIn",
    event: "scrollstop",
    skip_invisible : true
}).removeClass('lazy');

// lazy load to DOMNodeInserted event
$(document).bind('DOMNodeInserted', function(e) {
    $("img.lazy").lazyload({
        effect : "fadeIn",
        event: "scrollstop",
        skip_invisible : true
    }).removeClass('lazy');
});

so you don't need to place your configuration to every you ajax code

One line of code using jQuery:

$('td:nth-child(2)').hide();

// If your table has header(th), use this:
//$('td:nth-child(2),th:nth-child(2)').hide();

If ruby was installed in the following way:

./configure --prefix=/usr/local
make
sudo make install

You can uninstall it in the following way:

Check installed ruby version; lets assume 2.1.2

wget http://cache.ruby-lang.org/pub/ruby/2.1/ruby-2.1.2.tar.bz2
bunzip ...
tar xfv ...
cd ruby-2.1.2
./configure --prefix=/usr/local
make
sudo checkinstall
  # will build deb or rpm package and try to install it

After installation, you can now remove the package and it will remove the directories/files/etc.

sudo rpm -e ruby # or dpkg -P ruby (for Debian-like systems)

There might be some artifacts left:

Removing ruby ...
  warning: while removing ruby, directory '/usr/local/lib/ruby/gems/2.1.0/gems' not empty so not removed.
  ...

Remove them manually.

Have a look at XPCOM, there might be something that you can use if Firefox 3 is used by a client.

So, for future reference for anybody who doesn't want to spend two days searching the internet to figure this out, when you encode byte arrays into QR Codes, you have to use the ISO-8859-1character set, not UTF-8.

Prior to Oracle 12C you cannot select from PL/SQL-defined tables, only from tables based on SQL types like this:

CREATE OR REPLACE TYPE exch_row AS OBJECT(
currency_cd VARCHAR2(9),
exch_rt_eur NUMBER,
exch_rt_usd NUMBER);


CREATE OR REPLACE TYPE exch_tbl AS TABLE OF exch_row;

In Oracle 12C it is now possible to select from PL/SQL tables that are defined in a package spec.

Another solution that may help someone. There are 2 EditText which change instead of each other after editing. By default, it led to cyclicity.

use variable:

Boolean uahEdited = false;
Boolean usdEdited = false;

add TextWatcher

uahEdit = findViewById(R.id.uahEdit);
usdEdit = findViewById(R.id.usdEdit);

uahEdit.addTextChangedListener(new TextWatcher() {
        @Override
        public void beforeTextChanged(CharSequence s, int start, int count, int after) {
            if (!usdEdited) {
                uahEdited = true;
            }
        }

        @Override
        public void onTextChanged(CharSequence s, int start, int before, int count) {
            String tmp = uahEdit.getText().toString();

            if(!tmp.isEmpty() && uahEdited) {
                uah = Double.valueOf(tmp);
                usd = uah / 27;
                usdEdit.setText(String.valueOf(usd));
            } else if (tmp.isEmpty()) {
                usdEdit.getText().clear();
            }
        }

        @Override
        public void afterTextChanged(Editable s) {
            uahEdited = false;
        }
    });

usdEdit.addTextChangedListener(new TextWatcher() {
        @Override
        public void beforeTextChanged(CharSequence s, int start, int count, int after) {
            if (!uahEdited) {
                usdEdited = true;
            }
        }

        @Override
        public void onTextChanged(CharSequence s, int start, int before, int count) {
            String tmp = usdEdit.getText().toString();

            if (!tmp.isEmpty() && usdEdited) {
                usd = Double.valueOf(tmp);
                uah = usd * 27;
                uahEdit.setText(String.valueOf(uah));
            } else if (tmp.isEmpty()) {
                uahEdit.getText().clear();
            }
        }

        @Override
        public void afterTextChanged(Editable s) {
            usdEdited = false;
        }
    });

Don't criticize too much. I am a novice developer

If you want vertical sizing proportional to a width set in pixels on an enclosing div, I believe you need an extra element, like so:

#html

<div class="ptest">
    <div class="ptest-wrap">
        <div class="ptest-inner">
            Put content here
        </div>
    </div>
</div>

#css
.ptest {
  width: 200px;
  position: relative;
}

.ptest-wrap {
    padding-top: 60%;
}
.ptest-inner {
    position: absolute;
    top: 0;
    left: 0;
    right: 0;
    bottom: 0;
    background: #333;
}

Here's the 2 div solution that doesn't work. Note the 60% vertical padding is proportional to the window width, not the div.ptest width:

http://jsfiddle.net/d85FM/

Here's the example with the code above, which does work:

http://jsfiddle.net/mmq29/

Here's a simplest example from ASP.NET Community, this gave me a clear understanding on the concept....

what difference does this make?

For an example of this, here is a way to put focus on a text box on a page when the page is loaded into the browser—with Visual Basic using the RegisterStartupScript method:

Page.ClientScript.RegisterStartupScript(Me.GetType(), "Testing", _ 
"document.forms[0]['TextBox1'].focus();", True)

This works well because the textbox on the page is generated and placed on the page by the time the browser gets down to the bottom of the page and gets to this little bit of JavaScript.

But, if instead it was written like this (using the RegisterClientScriptBlock method):

Page.ClientScript.RegisterClientScriptBlock(Me.GetType(), "Testing", _
"document.forms[0]['TextBox1'].focus();", True)

Focus will not get to the textbox control and a JavaScript error will be generated on the page

The reason for this is that the browser will encounter the JavaScript before the text box is on the page. Therefore, the JavaScript will not be able to find a TextBox1.

This also did not work for me in Wordpress. I also tried -t and -n and other ways, but did not work. I used,

function pingAddress($ip) {
    $pingresult = exec("/bin/ping -c2 -w2 $ip", $outcome, $status);  
    if ($status==0) {
    $status = "alive";
    } else {
    $status = "dead";
    }
    $message .= '<div id="dialog-block-left">';
    $message .= '<div id="ip-status">The IP address, '.$ip.', is  '.$status.'</div><div style="clear:both"></div>';    
    return $message;
}
// Some IP Address
pingAddress("192.168.1.1"); 

This worked perfectly for me, finally. I referred this from http://www.phpscriptsdaily.com/php/php-ping/ Hope this will help

Well I want to modify this as it is working fine on my localhost but not on my live server For live server, I got another thing which now works for both local as well as live.

$fp = fSockOpen($ip,80,$errno,$errstr,1);
if($fp) { $status=0; fclose($fp); } else { $status=1; }

Then I show the Server is up for 0 and down for 1.

This works perfectly for me. I got this from Ping site and return result in PHP Thanks @karim79

You can use this approach to get the data from all the columns except one:-

1. Insert all the data into a temporary table
2. Then drop the column which you dont want from the temporary table
3. Fetch the data from the temporary table(This will not contain the data of the removed column)
4. Drop the temporary table

Something like this:

SELECT * INTO #TemporaryTable FROM YourTableName

ALTER TABLE #TemporaryTable DROP COLUMN Columnwhichyouwanttoremove

SELECT * FROM #TemporaryTable 

DROP TABLE #TemporaryTable 

For me (selectionChange) and the suggested (onSelectionChange) didn't work and I'm not using ReactiveForms. What I ended up doing was using the (valueChange) event like:

<mat-select (valueChange)="someFunction()">

And this worked for me

I had the same issue even when hardware acceleration installed. My solutions was uninstalling and reinstalling it using SDK Manager. Make sure you restart the Android studio after then.

Node.js itself offers an HTTP module, whose createServer method returns an object that you can use to respond to HTTP requests. That object inherits the http.Server prototype.

Which Oracle client are you using?

Oracle 64bit 11g client isn't support in PLSQL Developer. Try to install 32bits client.

That's pretty much all you need:

mysql> select * from t;
+------+-------+
| id   | data  |
+------+-------+
|    1 | max   |
|    2 | linda |
|    3 | sam   |
|    4 | henry |
+------+-------+
4 rows in set (0.02 sec)

mysql> update t set data=concat(data, 'a');
Query OK, 4 rows affected (0.01 sec)
Rows matched: 4  Changed: 4  Warnings: 0

mysql> select * from t;
+------+--------+
| id   | data   |
+------+--------+
|    1 | maxa   |
|    2 | lindaa |
|    3 | sama   |
|    4 | henrya |
+------+--------+
4 rows in set (0.00 sec)

Not sure why you'd be having trouble, though I am testing this on 5.1.41

I don't think there is a more "angular way" to select an element. See, for instance, the way they are achieving this goal in the last example of this old documentation page:

{
     template: '<div>' +
    '<div class="title">{{title}}</div>' +
    '<div class="body" ng-transclude></div>' +
    '</div>',

    link: function(scope, element, attrs) {
        // Title element
        var title = angular.element(element.children()[0]),
        // ...
    }
}

Support, unfortunately, is brutal at best. Here's a post on the topic:

https://www.campaignmonitor.com/blog/email-marketing/2013/02/embedded-images-in-html-email/

And the post content:

The only way UTF-8 affects std::string is that size(), length(), and all the indices are measured in bytes, not characters.

And, as sbi points out, incrementing the iterator provided by std::string will step forward by byte, not by character, so it can actually point into the middle of a multibyte UTF-8 codepoint. There's no UTF-8-aware iterator provided in the standard library, but there are a few available on the 'Net.

If you remember that, you can put UTF-8 into std::string, write it to a file, etc. all in the usual way (by which I mean the way you'd use a std::string without UTF-8 inside).

You may want to start your file with a byte order mark so that other programs will know it is UTF-8.

You can add an undecorated JDialog like this:

import java.awt.event.*;

import javax.swing.*;

public class TestSwing {
  public static void main(String[] args) throws Exception {
    JFrame frame = new JFrame("Parent");
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    frame.setSize(800, 600);
    frame.setVisible(true);

    final JDialog dialog = new JDialog(frame, "Child", true);    
    dialog.setSize(300, 200);
    dialog.setLocationRelativeTo(frame);
    JButton button = new JButton("Button");
    button.addActionListener(new ActionListener() {
      @Override
      public void actionPerformed(ActionEvent e) {
        dialog.dispose();
      }
    });
    dialog.add(button);
    dialog.setUndecorated(true);
    dialog.setVisible(true);
  }
}

Increase the width and height of view's frame with border width before adding the border:

float borderWidth = 2.0f
CGRect frame = self.frame;
frame.width += borderWidth;
frame.height += borderWidth;
 self.layer.borderColor = [UIColor yellowColor].CGColor;
 self.layer.borderWidth = 2.0f;

For muting library("name_of_library") codes, meanly just showing the codes, {r loadlib, echo=T, results='hide', message=F, warning=F} is great. And imho a better way than library(package, warn.conflicts=F, quietly=T)

This is because you're using getActivity() inside an inner class. Try using:

SherlockFragmentActivity.this.getActivity()

instead, though there's really no need for the getActivity() part. In your case, SherlockFragmentActivity .this should suffice.

This works for me

msg.BodyFormat = MailFormat.Html;

and then you can use html in your body

msg.Body = "<em>It's great to use HTML in mail!!</em>"

Last 5 rows retrieve in mysql

This query working perfectly

SELECT * FROM (SELECT * FROM recharge ORDER BY sno DESC LIMIT 5)sub ORDER BY sno ASC

or

select sno from(select sno from recharge order by sno desc limit 5) as t where t.sno order by t.sno asc

Another solution if you are running php script in CLI(cmd)

The php.ini file that needs edit is different in this case. In my WAMP installation the php.ini file that is loaded in command line is:

\wamp\bin\php\php5.5.12\php.ini

instead of \wamp\bin\apache\apache2.4.9\bin\php.ini which loads when php is run from browser

I'm not sure how far it will get you, but you can execute JavaScript one line at a time from the Developer Tool Console.

It will be proxy configuration of your browser. In NetWork Setting, use no proxy

For Manual proxy configuration add exception(No Proxy for in Firefox) like localhost:8080, localhost.

The jquery BalusC's solution improved by me. Used also: Brad Robertson's comment here.

Just put this in a .js, use the wide class for your desired combos and don't forge to give it an Id. Call the function in the onload (or documentReady or whatever).
As simple ass that :)
It will use the width that you defined for the combo as minimun length.

function fixIeCombos() {
    if ($.browser.msie && $.browser.version < 9) {
    var style = $('<style>select.expand { width: auto; }</style>');
    $('html > head').append(style);

    var defaultWidth = "200";

    // get predefined combo's widths.
    var widths = new Array();
    $('select.wide').each(function() {
        var width = $(this).width();
        if (!width) {
        width = defaultWidth;
        }
        widths[$(this).attr('id')] = width;
    });

    $('select.wide')
    .bind('focus mouseover', function() {
        // We're going to do the expansion only if the resultant size is bigger
        // than the original size of the combo.
        // In order to find out the resultant size, we first clon the combo as
        // a hidden element, add to the dom, and then test the width.
        var originalWidth = widths[$(this).attr('id')];

        var $selectClone = $(this).clone();
        $selectClone.addClass('expand').hide();
        $(this).after( $selectClone );
        var expandedWidth = $selectClone.width()
        $selectClone.remove();
        if (expandedWidth > originalWidth) {
        $(this).addClass('expand').removeClass('clicked');
        }
    })
    .bind('click', function() {
        $(this).toggleClass('clicked'); 
    })
    .bind('mouseout', function() {
        if (!$(this).hasClass('clicked')) {
        $(this).removeClass('expand');
        }
    })
    .bind('blur', function() {
        $(this).removeClass('expand clicked');
    })
    }
}

File extensions do not have any bearing or impact on the content of the file. You can hold YAML content in files with any extension: .yml, .yaml or indeed anything else.

The (rather sparse) YAML FAQ recommends that you use .yaml in preference to .yml, but for historic reasons many Windows programmers are still scared of using extensions with more than three characters and so opt to use .yml instead.

So, what really matters is what is inside the file, rather than what its extension is.

Just:

foreach ( $_POST as $key => $value) {

  echo "<p>".$key."</p>";
  echo "<p>".$value."</p>";
  echo "<hr />";

} 

On Windows I use this code:

void * G_pPointer = NULL;
const char * G_szPointerName = NULL;
void CheckPointerIternal()
{
    char cTest = *((char *)G_pPointer);
}
bool CheckPointerIternalExt()
{
    bool bRet = false;

    __try
    {
        CheckPointerIternal();
        bRet = true;
    }
    __except (EXCEPTION_EXECUTE_HANDLER)
    {
    }

    return  bRet;
}
void CheckPointer(void * A_pPointer, const char * A_szPointerName)
{
    G_pPointer = A_pPointer;
    G_szPointerName = A_szPointerName;
    if (!CheckPointerIternalExt())
        throw std::runtime_error("Invalid pointer " + std::string(G_szPointerName) + "!");
}

Usage:

unsigned long * pTest = (unsigned long *) 0x12345;
CheckPointer(pTest, "pTest"); //throws exception

this would explain how to write your own clientsideinlcude but jQuery is a lot, A LOT easier option ... plus you will gain a lot more by using jQuery anyways

$(window).scroll(function () {
  var Bottom = $(window).height() + $(window).scrollTop() >= $(document).height();
if(Bottom )
{
$('#div').hide();
}
});

I know this is probably the "obvious" answer, but it tripped me up for a bit. Make sure there's a dll for the project in the bin folder. When the service was published, the guy who published it deleted the dlls because he thought they were in the GAC. The one specifically for the project (QS.DialogManager.Communication.IISHost.RecipientService.dll, in this case) wasn't there.

Same error for a VERY different reason.

Just to expand on @splattne's answer a little:

MapPath(string virtualPath) calls the following:

public string MapPath(string virtualPath)
{
    return this.MapPath(VirtualPath.CreateAllowNull(virtualPath));
}

MapPath(VirtualPath virtualPath) in turn calls MapPath(VirtualPath virtualPath, VirtualPath baseVirtualDir, bool allowCrossAppMapping) which contains the following:

//...
if (virtualPath == null)
{
    virtualPath = VirtualPath.Create(".");
}
//...

So if you call MapPath(null) or MapPath(""), you are effectively calling MapPath(".")

use `json:"-"`

// Field is ignored by this package.
Field int `json:"-"`

// Field appears in JSON as key "myName".
Field int `json:"myName"`

// Field appears in JSON as key "myName" and
// the field is omitted from the object if its value is empty,
// as defined above.
Field int `json:"myName,omitempty"`

// Field appears in JSON as key "Field" (the default), but
// the field is skipped if empty.
// Note the leading comma.
Field int `json:",omitempty"`

This works for me especially in pivots table filtering when I want the count of cells with data on a filtered column. Reduce k accordingly (k - 1) if you have a header row for filtering:

k = Sheets("Sheet1").Range("$A:$A").SpecialCells(xlCellTypeVisible).SpecialCells(xlCellTypeConstants).Count

 Update 2020/05:
 Windows 10

first get a list of emulators, open cmd and run :

cd %homepath%\AppData\Local\Android\Sdk\emulator

then

emulator -list-avds

next create a shortcut of emulator.exe found in the directory above, then change the properties in it by editing the Target: text box like this

emulator.exe @YourDevice

To put the same text in a certain number of cells do the following:

1. Highlight the cells you want to put text into
2. Type into the cell you're currently in the data you want to be repeated
3. Hold Crtl and press 'return'

You will find that all the highlighted cells now have the same data in them. Have a nice day.

In my case, i had to save the file as UTF8 with BOM not just as UTF8 utf8 then this error was gone.

Quickest way to convert .ui to .py is from terminal:

pyuic4 -x input.ui -o output.py

Make sure you have pyqt4-dev-tools installed.

Replace this line cell.labelTitle.text = "This is a title"
with cell.labelTitle?.text = "This is a title"

Instead of the HTMLParser module, check out htmllib. It has a similar interface, but does more of the work for you. (It is pretty ancient, so it's not much help in terms of getting rid of javascript and css. You could make a derived class, but and add methods with names like start_script and end_style (see the python docs for details), but it's hard to do this reliably for malformed html.) Anyway, here's something simple that prints the plain text to the console

from htmllib import HTMLParser, HTMLParseError
from formatter import AbstractFormatter, DumbWriter
p = HTMLParser(AbstractFormatter(DumbWriter()))
try: p.feed('hello<br>there'); p.close() #calling close is not usually needed, but let's play it safe
except HTMLParseError: print ':(' #the html is badly malformed (or you found a bug)

With pure HTML you can't influence this - every modern browser (= the user) has complete control over this behavior because it has been misused a lot in the past...

HTML option

You can open a new window (HTML4) or a new browsing context (HTML5). Browsing context in modern browsers is mostly "new tab" instead of "new window". You have no influence on that, and you can't "force" modern browsers to open a new window.

In order to do this, use the anchor element's attribute target^[1]. The value you are looking for is _blank^[2].

<a href="www.example.com/example.html" target="_blank">link text</a>

JavaScript option

Forcing a new window is possible via javascript - see Ievgen's excellent answer below for a javascript solution.

(!) However, be aware, that opening windows via javascript (if not done in the onclick event from an anchor element) are subject to getting blocked by popup blockers!

_{[1] This attribute dates back to the times when browsers did not have tabs and using framesets was state of the art. In the meantime, the functionality of this attribute has slightly changed (see MDN Docu)}

_{[2] There are some other values which do not make much sense anymore (because they were designed with framesets in mind) like _parent, _self or _top.}

When you zip() together three lists containing 20 elements each, the result has twenty elements. Each element is a three-tuple.

See for yourself:

In [1]: a = b = c = range(20)

In [2]: zip(a, b, c)
Out[2]: 
[(0, 0, 0),
 (1, 1, 1),
 ...
 (17, 17, 17),
 (18, 18, 18),
 (19, 19, 19)]

To find out how many elements each tuple contains, you could examine the length of the first element:

In [3]: result = zip(a, b, c)

In [4]: len(result[0])
Out[4]: 3

Of course, this won't work if the lists were empty to start with.

There is a simple way.

1. You create an iframe which have for source something like "http://your-domain.com/index.php?url=http://the-site-you-want-to-get.com/unicorn

2. Then, you just get this url with $_GET and display the contents with file_get_contents($_GET['url']);

You will obtain an iframe which has a domain same than yours, then you will be able to use the $("iframe").contents().find("body") to manipulate the content.

You can try nvtop, which is similar to the widely-used htop tool but for NVIDIA GPUs. Here is a screenshot of nvtop of it in action.

Ok, something odd is happening here. To make this work, do NOT need to make any configuration changes in /etc/mysql/my.cnf . All you need to do is to restart the current mysql service in terminal:

sudo service mysql restart

Then if I want to "recreate" the bug, I simply restart the apache service:

sudo service apache2 restart

Which can then be fixed again by entering the following command:

sudo service mysql restart

So, it appears that the apache2 is doing something to not allow this feature when it starts up (which is then reversed/corrected if restart the mysql service).

Valid in Debian based distributions.

service mysqld restart
service httpd restart

Valid in RedHat based distributions

I compare strings using = and not <>. I've found out that in this context = seems to work in more reasonable fashion than <>. I have specified that two empty (or NULL) strings are equal. The real implementation returns PL/SQL boolean, but here I changed that to pls_integer (0 is false and 1 is true) to be able easily demonstrate the function.

create or replace function is_equal(a in varchar2, b in varchar2)
return pls_integer as
begin
  if a is null and b is null then
    return 1;
  end if;

  if a = b then
    return 1;
  end if;

  return 0;
end;
/
show errors

begin
  /* Prints 0 */
  dbms_output.put_line(is_equal('AAA', 'BBB'));
  dbms_output.put_line(is_equal('AAA', null));
  dbms_output.put_line(is_equal(null, 'BBB'));
  dbms_output.put_line(is_equal('AAA', ''));
  dbms_output.put_line(is_equal('', 'BBB'));

  /* Prints 1 */
  dbms_output.put_line(is_equal(null, null));
  dbms_output.put_line(is_equal(null, ''));
  dbms_output.put_line(is_equal('', ''));
  dbms_output.put_line(is_equal('AAA', 'AAA'));
end;

This issue may also occur if you have multiple versions of the same support library android-support-v4.jar. If your project is using other library projects that contain different-2 versions of the support library. To resolve the issue keep the same version of support library at each place.

-> is for pointers to a class instance

. is for class instances

:: is for classnames - for example when using a static member

With Python 3.4, the dependency is on Visual Studio 2010. Installing Visual C++ 2010 Express fixed the problem for me.

Tricking it into using the VS 2008 or 2013 installs that I happened to have didn't work.

When a variable is declared of a custom type (class), only a reference is created, which is called an object. At this stage, no memory is allocated to this object. It acts just as a pointer (to the location where the object will be stored in future). This process is called 'Declaration'.

Employee e; // e is an object

On the other hand, when a variable of custom type is declared using the new operator, which allocates memory in heap to this object and returns the reference to the allocated memory. This object which is now termed as instance. This process is called 'Instantiation'.

Employee e = new Employee(); // e is an instance

On the other hand, in some languages such as Java, an object is equivalent to an instance, as evident from the line written in Oracle's documentation on Java:

Note: The phrase "instantiating a class" means the same thing as "creating an object." When you create an object, you are creating an "instance" of a class, therefore "instantiating" a class.

Try this:

version: '3.5'
services:
  yourservice-here:
    container_name: container_name
    ports:
      - "4000:4000"
    extra_hosts: # <---- here
      - localhost:192.168.1.202
      - or-vitualhost.local:192.168.1.202

To get 192.168.1.202, uses ifconfig

This worked for me. Hope this help!

How about putting the long text in another <option> right below and disabling it? Might be a workaround for someone so posting here.

        <select>_x000D_
            <option>My real option text</option>_x000D_
            <option disabled style="font-style:italic">&nbsp;&nbsp;&nbsp;(...and my really really long option text that is basically a continuation of previous option)</option> _x000D_
            <option disabled style="font-style:italic">&nbsp;&nbsp;&nbsp;(...and still continuing my previous option)</option> _x000D_
            <option>Another real option text</option>_x000D_
        </select>

There is no direct string compare function in SQL Server

CASE
  WHEN str1 = str2 THEN 0
  WHEN str1 < str2 THEN -1
  WHEN str1 > str2 THEN 1
  ELSE NULL --one of the strings is NULL so won't compare (added on edit)
END

Notes

• you can wraps this via a UDF using CREATE FUNCTION etc
• you may need NULL handling (in my code above, any NULL will report 1)
• str1 and str2 will be column names or @variables

Komodo is wonderful, and it runs on OS X; they have a free version, Komodo Edit.

UPDATE from 2015: I've switched to PHPStorm from Jetbrains, the same folks that built IntelliJ IDEA and Resharper. It's better. Not just better. It's well worth the money.

Try with following:

public DataTable fillDataTable(string table)
    {
        string query = "SELECT * FROM dstut.dbo." +table;

        SqlConnection sqlConn = new SqlConnection(conSTR);
        sqlConn.Open();
        SqlCommand cmd = new SqlCommand(query, sqlConn);
        SqlDataAdapter da=new SqlDataAdapter(cmd);
        DataTable dt = new DataTable();
        da.Fill(dt);
        sqlConn.Close();
        return dt;
    }

Hope it is helpful.

Of course this will generate each pair twice as each for loop will go through every item of the list.

You could use some itertools magic here to generate all possible combinations:

import itertools
for a, b in itertools.combinations(mylist, 2):
    compare(a, b)

itertools.combinations will pair each element with each other element in the iterable, but only once.

You could still write this using index-based item access, equivalent to what you are used to, using nested for loops:

for i in range(len(mylist)):
    for j in range(i + 1, len(mylist)):
        compare(mylist[i], mylist[j])

Of course this may not look as nice and pythonic but sometimes this is still the easiest and most comprehensible solution, so you should not shy away from solving problems like that.

You can just use the View.setId(integer) for this. In the XML, even though you're setting a String id, this gets converted into an integer. Due to this, you can use any (positive) Integer for the Views you add programmatically.

According to View documentation

The identifier does not have to be unique in this view's hierarchy. The identifier should be a positive number.

So you can use any positive integer you like, but in this case there can be some views with equivalent id's. If you want to search for some view in hierarchy calling to setTag with some key objects may be handy.

Make sure you use the root folder of the JDK. Don't add "\lib" to the end of the path, where tools.jar is physically located. It took me an hour to figure that one out. Also, this post will help show you where Ant is looking for tools.jar:

Why does ANT tell me that JAVA_HOME is wrong when it is not?

http://www.java2s.com/Code/Java/Data-Type/Obtainingtheintegerandfractionalparts.htm

double num;
long iPart;
double fPart;

// Get user input
num = 2.3d;
iPart = (long) num;
fPart = num - iPart;
System.out.println("Integer part = " + iPart);
System.out.println("Fractional part = " + fPart);

Outputs:

Integer part = 2
Fractional part = 0.2999999999999998

KEEPING THE DIRECTORY NAME

The subdirectory-filter (or the shorter command git subtree) works good but did not work for me since they remove the directory name from the commit info. In my scenario I just want to merge parts of one repository into another and retain the history WITH full path name.

My solution was to use the tree-filter and to simply remove the unwanted files and directories from a temporary clone of the source repository, then pull from that clone into my target repository in 5 simple steps.

# 1. clone the source
git clone ssh://<user>@<source-repo url>
cd <source-repo>
# 2. remove the stuff we want to exclude
git filter-branch --tree-filter "rm -rf <files to exclude>" --prune-empty HEAD
# 3. move to target repo and create a merge branch (for safety)
cd <path to target-repo>
git checkout -b <merge branch>
# 4. Add the source-repo as remote 
git remote add source-repo <path to source-repo>
# 5. fetch it
git pull source-repo master
# 6. check that you got it right (better safe than sorry, right?)
gitk

if you have a data frame and want to remove all duplicates -- with reference to duplicates in a specific column (called 'colName'):

count before dedupe:

df.count()

do the de-dupe (convert the column you are de-duping to string type):

from pyspark.sql.functions import col
df = df.withColumn('colName',col('colName').cast('string'))

df.drop_duplicates(subset=['colName']).count()

can use a sorted groupby to check to see that duplicates have been removed:

df.groupBy('colName').count().toPandas().set_index("count").sort_index(ascending=False)

Many text-editors allow you to change to LF, see Atom instructions below. Simple and explicit.

Click CRLF on bottom right:

Select LF in dropdown on top:

<div id="scroller" style="height: 400px; width: 100%; overflow: auto;">
<iframe height="100%" id="iframe" scrolling="no" width="100%" src="url" />
</div>

I'm building my first site and this helped me get this working for all sites that I use iframe embededding for.

Thanks!

You can try to set_time_limit(n). However, if your PHP setup is running in safe mode, you can only change it from the php.ini file.

Just a note here that you may actually be better off having 3 separate SELECTS for reasons of optimization. If you have one single SELECT then the generated plan will have to project all columns col1, col2, col3, col7, col8 etc, although, depending on the value of the runtime @var, only some are needed. This may result in plans that do unnecessary clustered index lookups because the non-clustered index Doesn't cover all columns projected by the SELECT.

On the other hand 3 separate SELECTS, each projecting the needed columns only may benefit from non-clustered indexes that cover just your projected column in each case.

Of course this depends on the actual schema of your data model and the exact queries, but this is just a heads up so you don't bring the imperative thinking mind frame of procedural programming to the declarative world of SQL.

I launched ubuntu Xampp server on AWS amazon. And met the same problem with FTP, even though add user to group ftp SFTP and set permissions, owner group of htdocs folder. Finally find the reason in inbound rules in security group, added All TCP, 0 - 65535 rule(0.0.0.0/0,::/0) , then working right!

Yup, As @luizfelippe mentioned Session class has been removed since SDK 4.0. We need to use LoginManager.

I just looked into LoginButton class for logout. They are making this kind of check. They logs out only if accessToken is not null. So, I think its better to have this in our code too..

AccessToken accessToken = AccessToken.getCurrentAccessToken();
if(accessToken != null){
    LoginManager.getInstance().logOut();
}

Using bcrypt you can solve this issue. Extending the @Reem answer for someone who is trying to automate the process using bash and python.

#!/bin/bash

pip install bcrypt
yum install -y https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
yum -y install xmlstarlet

cat > /tmp/jenkinsHash.py <<EOF
import bcrypt
import sys

if not sys.argv[1]:
  sys.exit(10)

plaintext_pwd=sys.argv[1]
encrypted_pwd=bcrypt.hashpw(sys.argv[1], bcrypt.gensalt(rounds=10, prefix=b"2a"))
isCorrect=bcrypt.checkpw(plaintext_pwd, encrypted_pwd)

if not isCorrect:
   sys.exit(20);

print "{}".format(encrypted_pwd)
EOF

chmod +x /tmp/jenkinsHash.py
cd /var/lib/jenkins/users/admin*
pwd
while (( 1 )); do
    echo "Waiting for Jenkins to generate admin user's config file ..."

    if [[ -f "./config.xml" ]]; then
        break
    fi

    sleep 10
done

echo "Admin config file created"

admin_password=$(python /tmp/jenkinsHash.py password 2>&1)

# Repalcing the new passowrd
xmlstarlet -q ed --inplace -u "/user/properties/hudson.security.HudsonPrivateSecurityRealm_-Details/passwordHash" -v '#jbcrypt:'"$admin_password" config.xml

# Restart
systemctl restart jenkins
sleep 10

I have kept password hardcoded here but it can be a user input depending upon the requirement. Also make sure to add that sleep otherwise any other command revolving around Jenkins will fail.

For JDK 1.3 or earlier :

-Xnoagent -Djava.compiler=NONE -Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=6006

For JDK 1.4

-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=6006

For newer JDK :

-agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=6006

Please change the port number based on your needs.

From java technotes

From 5.0 onwards the -agentlib:jdwp option is used to load and specify options to the JDWP agent. For releases prior to 5.0, the -Xdebug and -Xrunjdwp options are used (the 5.0 implementation also supports the -Xdebug and -Xrunjdwp options but the newer -agentlib:jdwp option is preferable as the JDWP agent in 5.0 uses the JVM TI interface to the VM rather than the older JVMDI interface)

One more thing to note, from JVM Tool interface documentation:

JVM TI was introduced at JDK 5.0. JVM TI replaces the Java Virtual Machine Profiler Interface (JVMPI) and the Java Virtual Machine Debug Interface (JVMDI) which, as of JDK 6, are no longer provided.

You're missing service name:

 SQL> connect username/password@hostname:port/SERVICENAME

EDIT

If you can connect to the database from other computer try running there:

select sys_context('USERENV','SERVICE_NAME') from dual

and

select sys_context('USERENV','SID') from dual

Alternatively:

var keys = new List<string>(dicNumber.Keys);

You are halfway there. Try:

In [4]: a[a < 0] = 0

In [5]: a
Out[5]: array([1, 2, 3, 0, 5])

You can use a $where. Just be aware it will be fairly slow (has to execute Javascript code on every record) so combine with indexed queries if you can.

db.T.find( { $where: function() { return this.Grade1 > this.Grade2 } } );

or more compact:

db.T.find( { $where : "this.Grade1 > this.Grade2" } );

UPD for mongodb v.3.6+

you can use $expr as described in recent answer

Session Storage: It is same like local storage date except it will delete all windows when browser windows closed by a web user.

In Session storage can store upto 5 mb data

//set the value to a object in session storege
sessionStorage.myNameInSession = "Krishna";

Session: A session is a global variable stored on the server. Each session is assigned a unique id which is used to retrieve stored values.

Cookies: Cookies are data, stored in small text files as name-value pairs, on your computer. Once a cookie has been set, all page requests that follow return the cookie name and value.

I´ve found two problems with your Fiddle, one of the problems is first in Zeta´s answer.

the method is not toDataUrl(); is toDataURL(); and you forgot to store the canvas in your variable.

So the Fiddle now works fine http://jsfiddle.net/gfyWK/12/

I hope this helps!

say your array is called arr

do

arr[arr.Length - 1]

& is a character; & is a HTML character entity for that character.

<br> is an element. Elements don't get character entities.

In contrast to many answers here, \n or 
 are not equivalent to <br>. The former denotes a line break in text documents. The latter is intended to denote a line break in HTML documents and is doing that by virtue of its default CSS:

br:before { content: "\A"; white-space: pre-line }

A textual line break can be rendered as an HTML line break or can be treated as whitespace, depending on the CSS white-space property.

Possible. You can get commercial sport also.

JavaFXPorts is the name of the open source project maintained by Gluon that develops the code necessary for Java and JavaFX to run well on mobile and embedded hardware. The goal of this project is to contribute as much back to the OpenJFX project wherever possible, and when not possible, to maintain the minimal number of changes necessary to enable the goals of JavaFXPorts. Gluon takes the JavaFXPorts source code and compiles it into binaries ready for deployment onto iOS, Android, and embedded hardware. The JavaFXPorts builds are freely available on this website for all developers.
