The most basic way to iterate over a hash is as follows:

hash.each do |key, value|
  puts key
  puts value
end

Couldn't you just do this?

var things = [
    { id: 1, color: 'yellow' },
    { id: 2, color: 'blue' },
    { id: 3, color: 'red' }
];
$.post('@Url.Action("PassThings")', { things: things },
   function () {
        $('#result').html('"PassThings()" successfully called.');
   });

...and mark your action with

[HttpPost]
public void PassThings(IEnumerable<Thing> things)
{
    // do stuff with things here...
}

Here's another extension method:

    public static string Join(this IEnumerable<string> source, string separator)
    {
        return string.Join(separator, source);
    }

I managed to use soap,wsdl and Node.js You need to install soap with npm install soap

Create a node server called server.js that will define soap service to be consumed by a remote client. This soap service computes Body Mass Index based on weight(kg) and height(m).

const soap = require('soap');
const express = require('express');
const app = express();
/**
 * this is remote service defined in this file, that can be accessed by clients, who will supply args
 * response is returned to the calling client
 * our service calculates bmi by dividing weight in kilograms by square of height in metres
 */
const service = {
  BMI_Service: {
    BMI_Port: {
      calculateBMI(args) {
        //console.log(Date().getFullYear())
        const year = new Date().getFullYear();
        const n = args.weight / (args.height * args.height);
        console.log(n);
        return { bmi: n };
      }
    }
  }
};
// xml data is extracted from wsdl file created
const xml = require('fs').readFileSync('./bmicalculator.wsdl', 'utf8');
//create an express server and pass it to a soap server
const server = app.listen(3030, function() {
  const host = '127.0.0.1';
  const port = server.address().port;
});
soap.listen(server, '/bmicalculator', service, xml);

Next, create a client.js file that will consume soap service defined by server.js. This file will provide arguments for the soap service and call the url with SOAP's service ports and endpoints.

const express = require('express');
const soap = require('soap');
const url = 'http://localhost:3030/bmicalculator?wsdl';
const args = { weight: 65.7, height: 1.63 };
soap.createClient(url, function(err, client) {
  if (err) console.error(err);
  else {
    client.calculateBMI(args, function(err, response) {
      if (err) console.error(err);
      else {
        console.log(response);
        res.send(response);
      }
    });
  }
});

Your wsdl file is an xml based protocol for data exchange that defines how to access a remote web service. Call your wsdl file bmicalculator.wsdl

<definitions name="HelloService" targetNamespace="http://www.examples.com/wsdl/HelloService.wsdl"

Hope it helps

With the plugin: jQuery Selection Box. You can do this:

var myOptions = {
        "Value 1" : "Text 1",
        "Value 2" : "Text 2",
        "Value 3" : "Text 3"
    }
    $("#myselect2").addOption(myOptions, false); 

If your function returns a value via reference, the compiler cannot store it in a register when calling other functions because, theoretically, the first function can save the address of the variable passed to it in a globally accessible variable, and any subsecuently called functions may change it, so the compiler will have (1) save the value from registers back to memory before calling other functions and (2) re-read it when it is needed from the memory again after any of such calls.

If you return by reference, optimization of your program will suffer

Basically like this,

<?php
$link = ""; // Link goes here!
print "<a href="'.$link.'">Link</a>";
?>

try to disable the rewrite module in ubuntu using sudo a2dismod rewrite. This will perhaps stop your apache server to crash.

When doing django ranges with a filter make sure you know the difference between using a date object vs a datetime object. __range is inclusive on dates but if you use a datetime object for the end date it will not include the entries for that day if the time is not set.

    startdate = date.today()
    enddate = startdate + timedelta(days=6)
    Sample.objects.filter(date__range=[startdate, enddate])

returns all entries from startdate to enddate including entries on those dates. Bad example since this is returning entries a week into the future, but you get the drift.

    startdate = datetime.today()
    enddate = startdate + timedelta(days=6)
    Sample.objects.filter(date__range=[startdate, enddate])

will be missing 24 hours worth of entries depending on what the time for the date fields is set to.

Another solution that wasn't mentioned:

Example Here

var parent = document.querySelector('.parent');

if (parent.querySelector('.child') !== null) {
    // .. it's a child
}

It doesn't matter whether the element is a direct child, it will work at any depth.

Alternatively, using the .contains() method:

Example Here

var parent = document.querySelector('.parent'),
    child = document.querySelector('.child');

if (parent.contains(child)) {
    // .. it's a child
}

Don't join like that. It's a really really bad practice!!! It will slow down the performance in fetching with massive data. For example, if there were 100 rows in each tables, database server have to fetch 100x100x100 = 1000000 times. It had to fetch for 1 million times. To overcome that problem, join the first two table that can fetch result in minimum possible matching(It's up to your database schema). Use that result in Subquery and then join it with the third table and fetch it. For the very first join --> 100x100= 10000 times and suppose we get 5 matching result. And then we join the third table with the result --> 5x100 = 500. Total fetch = 10000+500 = 10200 times only. And thus, the performance went up!!!

make sure your doSomething function is not static.

If you can re-create or parse your input data, you can specify an escape character for the CREATE TABLE:

ROW FORMAT DELIMITED FIELDS TERMINATED BY "," ESCAPED BY '\\';

Will accept this line as 4 fields

1,some text\, with comma in it,123,more text

preg_match('/'.preg_quote('^\'£$%^&*()}{@#~?><,@|-=-_+-¬', '/').'/', $string);

TLDR:

- You can't hash a list, a set, nor a dict to put that into sets

- You can hash a tuple to put it into a set.

Example:

>>> {1, 2, [3, 4]}
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: unhashable type: 'list'

>>> {1, 2, (3, 4)}
set([1, 2, (3, 4)])

Note that hashing is somehow recursive and the above holds true for nested items:

>>> {1, 2, 3, (4, [2, 3])}
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: unhashable type: 'list'

Dict keys also are hashable, so the above holds for dict keys too.

try the following code

select * from TableA A 
inner join TableB B on A.Column=B.Column 
inner join TableC C on A.Column=C.Column

absolute positioning is evil... this solution doesn't take into account window size. If you resize the browser window, your div will be out of place!

There is an experimental release by Microsoft of Interactive Extensions to LINQ (also on NuGet, see RxTeams's profile for more links). The Channel 9 video explains it well.

Its docs are only provided in XML format. I have run this documentation in Sandcastle to allow it to be in a more readable format. Unzip the docs archive and look for index.html.

Among many other goodies, it provides the expected ForEach implementation. It allows you to write code like this:

int[] numbers = { 1, 2, 3, 4, 5, 6, 7, 8 };

numbers.ForEach(x => Console.WriteLine(x*x));

Short addition to the above for openJDK 11 with android sdk tools before upgrading to the latest version.

The above solutions didn't work for me

set DEFAULT_JVM_OPTS="-Dcom.android.sdklib.toolsdir=%~dp0\.."

To get this working I have installed the jaxb-ri (reference implementation) from the maven repo.

The information was given https://github.com/javaee/jaxb-v2 and links to the https://repo1.maven.org/maven2/com/sun/xml/bind/jaxb-ri/2.3.2/jaxb-ri-2.3.2.zip
This download includes a standalone runtime implementation in the mod-Folder.

I copied the mod-Folder to $android_sdk\tools\lib\ and added the following to classpath variable:

;%APP_HOME%\lib\mod\jakarta.xml.bind-api.jar;%APP_HOME%\lib\mod\jakarta.activation-api.jar;%APP_HOME%\lib\mod\jaxb-runtime.jar;%APP_HOME%\lib\mod\istack-commons-runtime.jar;

So finally it looks like:

set CLASSPATH=%APP_HOME%\lib\dvlib-26.0.0-dev.jar;%APP_HOME%\lib\jimfs-1.1.jar;%APP_HOME%\lib\jsr305-1.3.9.jar;%APP_HOME%\lib\repository-26.0.0-dev.jar;%APP_HOME%\lib\j2objc-annotations-1.1.jar;%APP_HOME%\lib\layoutlib-api-26.0.0-dev.jar;%APP_HOME%\lib\gson-2.3.jar;%APP_HOME%\lib\httpcore-4.2.5.jar;%APP_HOME%\lib\commons-logging-1.1.1.jar;%APP_HOME%\lib\commons-compress-1.12.jar;%APP_HOME%\lib\annotations-26.0.0-dev.jar;%APP_HOME%\lib\error_prone_annotations-2.0.18.jar;%APP_HOME%\lib\animal-sniffer-annotations-1.14.jar;%APP_HOME%\lib\httpclient-4.2.6.jar;%APP_HOME%\lib\commons-codec-1.6.jar;%APP_HOME%\lib\common-26.0.0-dev.jar;%APP_HOME%\lib\kxml2-2.3.0.jar;%APP_HOME%\lib\httpmime-4.1.jar;%APP_HOME%\lib\annotations-12.0.jar;%APP_HOME%\lib\sdklib-26.0.0-dev.jar;%APP_HOME%\lib\guava-22.0.jar;%APP_HOME%\lib\mod\jakarta.xml.bind-api.jar;%APP_HOME%\lib\mod\jakarta.activation-api.jar;%APP_HOME%\lib\mod\jaxb-runtime.jar;%APP_HOME%\lib\mod\istack-commons-runtime.jar;

Maybe I missed a lib due to some minor errors showing up. But sdkmanager.bat --update or --list is running now.

Use data type 'MultilineText':

[DataType(DataType.MultilineText)]
public string Text { get; set; }

See ASP.NET MVC3 - textarea with @Html.EditorFor

Reference taken from this blog:

Below is a list of hashing algorithm along with its require bit size:

• MD5 = 128-bit hash value.
• SHA1 = 160-bit hash value.
• SHA224 = 224-bit hash value.
• SHA256 = 256-bit hash value.
• SHA384 = 384-bit hash value.
• SHA512 = 512-bit hash value.

Created one sample table with require CHAR(n):

CREATE TABLE tbl_PasswordDataType
(
    ID INTEGER
    ,MD5_128_bit CHAR(32)
    ,SHA_160_bit CHAR(40)
    ,SHA_224_bit CHAR(56)
    ,SHA_256_bit CHAR(64)
    ,SHA_384_bit CHAR(96)
    ,SHA_512_bit CHAR(128)
); 
INSERT INTO tbl_PasswordDataType
VALUES 
(
    1
    ,MD5('SamplePass_WithAddedSalt')
    ,SHA1('SamplePass_WithAddedSalt')
    ,SHA2('SamplePass_WithAddedSalt',224)
    ,SHA2('SamplePass_WithAddedSalt',256)
    ,SHA2('SamplePass_WithAddedSalt',384)
    ,SHA2('SamplePass_WithAddedSalt',512)
);

If you sort the strings "12", "15" and "5" then "5" comes last because "5" > "1". i.e. the natural ordering of Strings doesn't work the way you expect.

If you want to store strings in your list but sort them numerically then you will need to use a comparator that handles this. e.g.

Collections.sort(list, new Comparator<String>() {
    public int compare(String o1, String o2) {
        Integer i1 = Integer.parseInt(o1);
        Integer i2 = Integer.parseInt(o2);
        return (i1 > i2 ? -1 : (i1 == i2 ? 0 : 1));
    }
});

Also, I think you are getting slightly mixed up between Collection types. A HashSet and a HashMap are different things.

A little cheat sheet on module queries.

To check all existing versions: e.g. go list -m -versions github.com/gorilla/mux

1. Specific version @v1.2.8
2. Specific commit @c783230
3. Specific branch @master
4. Version prefix @v2
5. Comparison @>=2.1.5
6. Latest @latest

E.g. go get github.com/gorilla/[email protected]

For linux you can install it via

sudo apt-get install php5-curl

For Windows(removing the ;) from php.ini

;extension=php_curl.dll

Restart apache server.

here a concatenation solution:

  {
    text = realloc( text, strlen(text)+1+strlen(buffer) );
    if( !text ) ... /* error handling */
    strcat( text, buffer ); /* note a '\n' is appended here everytime */

navigationView.setItemTextColor(ColorStateList.valueOf(Color.WHITE));

Note that if strings has spaces then quotation marks are needed at definition and must be chopped while concatenating:

rem The retail files set
set FILES_SET="(*.exe *.dll"

rem The debug extras files set
set DEBUG_EXTRA=" *.pdb"

rem Build the DEBUG set without any
set FILES_SET=%FILES_SET:~1,-1%%DEBUG_EXTRA:~1,-1%

rem Append the closing bracket
set FILES_SET=%FILES_SET%)

echo %FILES_SET%

Cheers...

the line

age=document.getElementById("age").value;

says 'the variable I called 'age' has the value of the element with id 'age'. In this case the input field.

The line

voteable=(age<18)?"Too young":"Old enough";

says in a variable I called 'voteable' I store the value following the rule :

"If age is under 18 then show 'Too young' else show 'Old enough'"

The last line tell to put the value of 'voteable' in the element with id 'demo' (in this case the 'p' element)

git log -1 --abbrev-commit

will also do it.

git log --abbrev-commit

will list the log entries with abbreviated SHA-1 checksum.

I had similar problem on a CentOS VPS. If MySQL won't start or keeps crashing right after it starts, try these steps:

1) Find my.cnf file (mine was located in /etc/my.cnf) and add the line:

innodb_force_recovery = X

replacing X with a number from 1 to 6, starting from 1 and then incrementing if MySQL won't start. Setting to 4, 5 or 6 can delete your data so be carefull and read http://dev.mysql.com/doc/refman/5.7/en/forcing-innodb-recovery.html before.

2) Restart MySQL service. Only SELECT will run and that's normal at this point.

3) Dump all your databases/schemas with mysqldump one by one, do not compress the dumps because you'd have to uncompress them later anyway.

4) Move (or delete!) only the bd's directories inside /var/lib/mysql, preserving the individual files in the root.

5) Stop MySQL and then uncomment the line added in 1). Start MySQL.

6) Recover all bd's dumped in 3).

Good luck!

Python dictionaries don't support duplicate keys. One way around is to store lists or sets inside the dictionary.

One easy way to achieve this is by using defaultdict:

from collections import defaultdict

data_dict = defaultdict(list)

All you have to do is replace

data_dict[regNumber] = details

with

data_dict[regNumber].append(details)

and you'll get a dictionary of lists.

I've just downloaded SQL Developer 4.0 for OS X (10.9), it just got out of beta. I also downloaded the latest Postgres JDBC jar. On a lark I decided to install it (same method as other third party db drivers in SQL Dev), and it accepted it. Whenever I click "new connection", there is a tab now for Postgres... and clicking it shows a panel that asks for the database connection details.

The answer to this question has changed, whether or not it is supported, it seems to work. There is a "choose database" button, that if clicked, gives you a dropdown list filled with available postgres databases. You create the connection, open it, and it lists the schemas in that database. Most postgres commands seem to work, though no psql commands (\list, etc).

Those who need a single tool to connect to multiple database engines can now use SQL Developer.

Solr currently checks for a "pure negative" query and inserts *:* (which matches all documents) so that it works correctly.

-foo is transformed by solr into (*:* -foo)

The big caveat is that Solr only checks to see if the top level query is a pure negative query! So this means that a query like bar OR (-foo) is not changed since the pure negative query is in a sub-clause of the top level query. You need to transform this query yourself into bar OR (*:* -foo)

You may check the solr query explanation to verify the query transformation:

?q=-title:foo&debug=query

is transformed to

(+(-title:foo +MatchAllDocsQuery(*:*))

Although the selected answer is correct, I just want to further elaborate it. I found here a useful Custom Adapter for multiple View Types in RecyclerView. Its Kotlin version is here.

Custom Adapter is following

public class CustomAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder> {
private final Context context;
ArrayList<String> list; // ArrayList of your Data Model
final int VIEW_TYPE_ONE = 1;
final int VIEW_TYPE_TWO = 2;

public CustomAdapter(Context context, ArrayList<String> list) { // you can pass other parameters in constructor
    this.context = context;
    this.list = list;
}

private class ViewHolder1 extends RecyclerView.ViewHolder {

    TextView yourView;
    ViewHolder1(final View itemView) {
        super(itemView);
        yourView = itemView.findViewById(R.id.yourView); // Initialize your All views prensent in list items
    }
    void bind(int position) {
        // This method will be called anytime a list item is created or update its data
        //Do your stuff here
        yourView.setText(list.get(position));
    }
}

private class ViewHolder2 extends RecyclerView.ViewHolder {

    TextView yourView;
    ViewHolder2(final View itemView) {
        super(itemView);
        yourView = itemView.findViewById(R.id.yourView); // Initialize your All views prensent in list items
    }
    void bind(int position) {
        // This method will be called anytime a list item is created or update its data
        //Do your stuff here
        yourView.setText(list.get(position));
    }
}

@Override
public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
   if (viewType == VIEW_TYPE_ONE) {
       return new ViewHolder1(LayoutInflater.from(context).inflate(R.layout.your_list_item_1, parent, false));
   }
   //if its not VIEW_TYPE_ONE then its VIEW_TYPE_TWO
   return new ViewHolder2(LayoutInflater.from(context).inflate(R.layout.your_list_item_2, parent, false));

}

@Override
public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {
    if (list.get(position).type == Something) { // put your condition, according to your requirements
        ((ViewHolder1) holder).bind(position);
    } else {
        ((ViewHolder2) holder).bind(position);
    }

}

@Override
public int getItemCount() {
    return list.size();
}

@Override
public int getItemViewType(int position) {
    // here you can get decide from your model's ArrayList, which type of view you need to load. Like
    if (list.get(position).type == Something) { // put your condition, according to your requirements
        return VIEW_TYPE_ONE;
    }
    return VIEW_TYPE_TWO;
}
}

I ran into a problem that my js was not executing when the user had clicked back or forward. I first set out to stop the browser from caching, but this didn't seem to be the problem. My javascript was set to execute after all of the libraries etc. were loaded. I checked these with the readyStateChange event.

After some testing I found out that the readyState of an element in a page where back has been clicked is not 'loaded' but 'complete'. Adding || element.readyState == 'complete' to my conditional statement solved my problems.

Just thought I'd share my findings, hopefully they will help someone else.

Edit for completeness

My code looked as follows:

script.onreadystatechange(function(){ 
   if(script.readyState == 'loaded' || script.readyState == 'complete') {
      // call code to execute here.
   } 
});

In the code sample above the script variable was a newly created script element which had been added to the DOM.

Try the following query:

;WITH CTE_DocTotal
 AS
 (
   SELECT SUM(Sale + VAT) AS DocTotal_1
   FROM PEDI_InvoiceDetail
   GROUP BY InvoiceNumber
 )

UPDATE CTE_DocTotal
SET DocTotal = CTE_DocTotal.DocTotal_1

Yes it stops execution so this is generally preferable to HAVING COUNT(*) > 0 which often won't.

With EXISTS if you look at the execution plan you will see that the actual number of rows coming out of table1 will not be more than 1 irrespective of number of matching records.

In some circumstances SQL Server can convert the tree for the COUNT query to the same as the one for EXISTS during the simplification phase (with a semi join and no aggregate operator in sight) an example of that is discussed in the comments here.

For more complicated sub trees than shown in the question you may occasionally find the COUNT performs better than EXISTS however. Because the semi join needs only retrieve one row from the sub tree this can encourage a plan with nested loops for that part of the tree - which may not work out optimal in practice.

NOTE The question in the bounty by @WilliamJockusch and the original question are different.

This answer is about StackOverflow's in the general case of third-party libraries and what you can/can't do with them. If you're looking about the special case with XslTransform, see the accepted answer.

Stack overflows happen because the data on the stack exceeds a certain limit (in bytes). The details of how this detection works can be found here.

I'm wondering if there is a general way to track down StackOverflowExceptions. In other words, suppose I have infinite recursion somewhere in my code, but I have no idea where. I want to track it down by some means that is easier than stepping through code all over the place until I see it happening. I don't care how hackish it is.

As I mentioned in the link, detecting a stack overflow from static code analysis would require solving the halting problem which is undecidable. Now that we've established that there is no silver bullet, I can show you a few tricks that I think helps track down the problem.

I think this question can be interpreted in different ways, and since I'm a bit bored :-), I'll break it down into different variations.

Detecting a stack overflow in a test environment

Basically the problem here is that you have a (limited) test environment and want to detect a stack overflow in an (expanded) production environment.

Instead of detecting the SO itself, I solve this by exploiting the fact that the stack depth can be set. The debugger will give you all the information you need. Most languages allow you to specify the stack size or the max recursion depth.

Basically I try to force a SO by making the stack depth as small as possible. If it doesn't overflow, I can always make it bigger (=in this case: safer) for the production environment. The moment you get a stack overflow, you can manually decide if it's a 'valid' one or not.

To do this, pass the stack size (in our case: a small value) to a Thread parameter, and see what happens. The default stack size in .NET is 1 MB, we're going to use a way smaller value:

class StackOverflowDetector
{
    static int Recur()
    {
        int variable = 1;
        return variable + Recur();
    }

    static void Start()
    {
        int depth = 1 + Recur();
    }

    static void Main(string[] args)
    {
        Thread t = new Thread(Start, 1);
        t.Start();
        t.Join();
        Console.WriteLine();
        Console.ReadLine();
    }
}

Note: we're going to use this code below as well.

Once it overflows, you can set it to a bigger value until you get a SO that makes sense.

Creating exceptions before you SO

The StackOverflowException is not catchable. This means there's not much you can do when it has happened. So, if you believe something is bound to go wrong in your code, you can make your own exception in some cases. The only thing you need for this is the current stack depth; there's no need for a counter, you can use the real values from .NET:

class StackOverflowDetector
{
    static void CheckStackDepth()
    {
        if (new StackTrace().FrameCount > 10) // some arbitrary limit
        {
            throw new StackOverflowException("Bad thread.");
        }
    }

    static int Recur()
    {
        CheckStackDepth();
        int variable = 1;
        return variable + Recur();
    }

    static void Main(string[] args)
    {
        try
        {
            int depth = 1 + Recur();
        }
        catch (ThreadAbortException e)
        {
            Console.WriteLine("We've been a {0}", e.ExceptionState);
        }
        Console.WriteLine();
        Console.ReadLine();
    }
}

Note that this approach also works if you are dealing with third-party components that use a callback mechanism. The only thing required is that you can intercept some calls in the stack trace.

Detection in a separate thread

You explicitly suggested this, so here goes this one.

You can try detecting a SO in a separate thread.. but it probably won't do you any good. A stack overflow can happen fast, even before you get a context switch. This means that this mechanism isn't reliable at all... I wouldn't recommend actually using it. It was fun to build though, so here's the code :-)

class StackOverflowDetector
{
    static int Recur()
    {
        Thread.Sleep(1); // simulate that we're actually doing something :-)
        int variable = 1;
        return variable + Recur();
    }

    static void Start()
    {
        try
        {
            int depth = 1 + Recur();
        }
        catch (ThreadAbortException e)
        {
            Console.WriteLine("We've been a {0}", e.ExceptionState);
        }
    }

    static void Main(string[] args)
    {
        // Prepare the execution thread
        Thread t = new Thread(Start);
        t.Priority = ThreadPriority.Lowest;

        // Create the watch thread
        Thread watcher = new Thread(Watcher);
        watcher.Priority = ThreadPriority.Highest;
        watcher.Start(t);

        // Start the execution thread
        t.Start();
        t.Join();

        watcher.Abort();
        Console.WriteLine();
        Console.ReadLine();
    }

    private static void Watcher(object o)
    {
        Thread towatch = (Thread)o;

        while (true)
        {
            if (towatch.ThreadState == System.Threading.ThreadState.Running)
            {
                towatch.Suspend();
                var frames = new System.Diagnostics.StackTrace(towatch, false);
                if (frames.FrameCount > 20)
                {
                    towatch.Resume();
                    towatch.Abort("Bad bad thread!");
                }
                else
                {
                    towatch.Resume();
                }
            }
        }
    }
}

Run this in the debugger and have fun of what happens.

Using the characteristics of a stack overflow

Another interpretation of your question is: "Where are the pieces of code that could potentially cause a stack overflow exception?". Obviously the answer of this is: all code with recursion. For each piece of code, you can then do some manual analysis.

It's also possible to determine this using static code analysis. What you need to do for that is to decompile all methods and figure out if they contain an infinite recursion. Here's some code that does that for you:

// A simple decompiler that extracts all method tokens (that is: call, callvirt, newobj in IL)
internal class Decompiler
{
    private Decompiler() { }

    static Decompiler()
    {
        singleByteOpcodes = new OpCode[0x100];
        multiByteOpcodes = new OpCode[0x100];
        FieldInfo[] infoArray1 = typeof(OpCodes).GetFields();
        for (int num1 = 0; num1 < infoArray1.Length; num1++)
        {
            FieldInfo info1 = infoArray1[num1];
            if (info1.FieldType == typeof(OpCode))
            {
                OpCode code1 = (OpCode)info1.GetValue(null);
                ushort num2 = (ushort)code1.Value;
                if (num2 < 0x100)
                {
                    singleByteOpcodes[(int)num2] = code1;
                }
                else
                {
                    if ((num2 & 0xff00) != 0xfe00)
                    {
                        throw new Exception("Invalid opcode: " + num2.ToString());
                    }
                    multiByteOpcodes[num2 & 0xff] = code1;
                }
            }
        }
    }

    private static OpCode[] singleByteOpcodes;
    private static OpCode[] multiByteOpcodes;

    public static MethodBase[] Decompile(MethodBase mi, byte[] ildata)
    {
        HashSet<MethodBase> result = new HashSet<MethodBase>();

        Module module = mi.Module;

        int position = 0;
        while (position < ildata.Length)
        {
            OpCode code = OpCodes.Nop;

            ushort b = ildata[position++];
            if (b != 0xfe)
            {
                code = singleByteOpcodes[b];
            }
            else
            {
                b = ildata[position++];
                code = multiByteOpcodes[b];
                b |= (ushort)(0xfe00);
            }

            switch (code.OperandType)

            CheckRecursion(method, calling, new HashSet<MethodBase>());
        }
    }

Now, the fact that a method cycle contains recursion, is by no means a guarantee that a stack overflow will happen - it's just the most likely precondition for your stack overflow exception. In short, this means that this code will determine the pieces of code where a stack overflow can occur, which should narrow down most code considerably.

Yet other approaches

There are some other approaches you can try that I haven't described here.

1. Handling the stack overflow by hosting the CLR process and handling it. Note that you still cannot 'catch' it.
2. Changing all IL code, building another DLL, adding checks on recursion. Yes, that's quite possible (I've implemented it in the past :-); it's just difficult and involves a lot of code to get it right.
3. Use the .NET profiling API to capture all method calls and use that to figure out stack overflows. For example, you can implement checks that if you encounter the same method X times in your call tree, you give a signal. There's a project here that will give you a head start.

The following worked well for me

try {
    asdf
} catch {
    $string_err = $_ | Out-String
}

write-host $string_err

The result of this is the following as a string instead of an ErrorRecord object

asdf : The term 'asdf' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.

    + CategoryInfo          : ObjectNotFound: (asdf:String) [], CommandNotFoundException
    + FullyQualifiedErrorId : CommandNotFoundException

There is one more solution to set column Full text to true.

These solution for example didn't work for me

ALTER TABLE news ADD FULLTEXT(headline, story);

My solution.

1. Right click on table
2. Design
3. Right Click on column which you want to edit
4. Full text index
5. Add
6. Close
7. Refresh

NEXT STEPS

1. Right click on table
2. Design
3. Click on column which you want to edit
4. On bottom of mssql you there will be tab "Column properties"
5. Full-text Specification -> (Is Full-text Indexed) set to true.

Refresh

I had the same problem, in my case i resolved it by:

1) going to File-->Project Structure---->Global libraries 2) looking for jfxrt.jar included as default in the jdk1.8.0_241\lib (after installing it) 3)click on + on top left to add new global library and i specified the path of my jdk1.8.0_241 Ex :(C:\Program Files\Java\jdk1.8.0_241).

I hope this will help you

Just an additional note - if the server runs on a port other than 80 (as might be common on a development/intranet machine) then HTTP_HOST contains the port, while SERVER_NAME does not.

$_SERVER['HTTP_HOST'] == 'localhost:8080'
$_SERVER['SERVER_NAME'] == 'localhost'

(At least that's what I've noticed in Apache port-based virtualhosts)

As Mike has noted below, HTTP_HOST does not contain :443 when running on HTTPS (unless you're running on a non-standard port, which I haven't tested).

I have fixed it with removing below code from

C:\wamp\bin\apache\apache2.4.9\conf\extra\httpd-vhosts.conf file

<VirtualHost *:80>
    ServerAdmin [email protected]
    DocumentRoot "c:/Apache24/docs/dummy-host.example.com"
    ServerName dummy-host.example.com
    ServerAlias www.dummy-host.example.com
    ErrorLog "logs/dummy-host.example.com-error.log"
    CustomLog "logs/dummy-host.example.com-access.log" common
 </VirtualHost>

<VirtualHost *:80>
    ServerAdmin [email protected]
    DocumentRoot "c:/Apache24/docs/dummy-host2.example.com"
    ServerName dummy-host2.example.com
    ErrorLog "logs/dummy-host2.example.com-error.log"
    CustomLog "logs/dummy-host2.example.com-access.log" common
</VirtualHost>

And added

<VirtualHost *:80>
    ServerAdmin webmaster@localhost
    DocumentRoot "c:/wamp/www"
    ServerName localhost
    ErrorLog "logs/localhost-error.log"
    CustomLog "logs/localhost-access.log" common
</VirtualHost>

And it has worked like charm

Using environment variable is sometimes more convenient when you do not control the build scripts / process.

For C includes use C_INCLUDE_PATH.

For C++ includes use CPLUS_INCLUDE_PATH.

See this link for other gcc environment variables.

Example usage in MacOS / Linux

# `pip install` will automatically run `gcc` using parameters
# specified in the `asyncpg` package (that I do not control)

C_INCLUDE_PATH=/home/scott/.pyenv/versions/3.7.9/include/python3.7m pip install asyncpg

Example usage in Windows

set C_INCLUDE_PATH="C:\Users\Scott\.pyenv\versions\3.7.9\include\python3.7m"

pip install asyncpg

# clear the environment variable so it doesn't affect other builds
set C_INCLUDE_PATH=

You can do this using the splat operator:

some_func(*params)

This causes the function to receive each list item as a separate parameter. There's a description here: http://docs.python.org/tutorial/controlflow.html#unpacking-argument-lists

DSO here means Dynamic Shared Object; since the error message says it's missing from the command line, I guess you have to add it to the command line.

That is, try adding -lpthread to your command line.

As others have said, you can/should prepend the string with @ (though you could also just escape the backslashes), but what they glossed over (that is, didn't bring it up despite making a change related to it) was the fact that, as I recently discovered, using \ at the beginning of a pathname, without . to represent the current directory, refers to the root of the current directory tree.

C:\foo\bar>cd \
C:\>

versus

C:\foo\bar>cd .\
C:\foo\bar>

(Using . by itself has the same effect as using .\ by itself, from my experience. I don't know if there are any specific cases where they somehow would not mean the same thing.)

You could also just leave off the leading .\ , if you want.

C:\foo>cd bar
C:\foo\bar>

In fact, if you really wanted to, you don't even need to use backslashes. Forwardslashes work perfectly well! (Though a single / doesn't alias to the current drive root as \ does.)

C:\>cd foo/bar
C:\foo\bar>

You could even alternate them.

C:\>cd foo/bar\baz
C:\foo\bar\baz>

...I've really gone off-topic here, though, so feel free to ignore all this if you aren't interested.

Another way could be to compile the code first in watch mode with tsc -w and then use nodemon over javascript. This method is similar in speed to ts-node-dev and has the advantage of being more production-like.

 "scripts": {
    "watch": "tsc -w",
    "dev": "nodemon dist/index.js"
  },

I have just installed the JDK for version 21 of Java SE 7 and found that it is installed in a different directory from Apple's Java 6. It is in /Library/Java... rather then in /System/Library/Java.... Running /usr/libexec/java_home -v 1.7 versus -v 1.6 will confirm this.

Here is my improved solution of Bruno Bronosky's answer using variable arrays.

it lets you mix parameters position and give you a parameter array preserving the order without the options

#!/bin/bash

echo $@

PARAMS=()
SOFT=0
SKIP=()
for i in "$@"
do
case $i in
    -n=*|--skip=*)
    SKIP+=("${i#*=}")
    ;;
    -s|--soft)
    SOFT=1
    ;;
    *)
        # unknown option
        PARAMS+=("$i")
    ;;
esac
done
echo "SKIP            = ${SKIP[@]}"
echo "SOFT            = $SOFT"
    echo "Parameters:"
    echo ${PARAMS[@]}

Will output for example:

$ ./test.sh parameter -s somefile --skip=.c --skip=.obj
parameter -s somefile --skip=.c --skip=.obj
SKIP            = .c .obj
SOFT            = 1
Parameters:
parameter somefile

You can use os.sep:

>>> import os
>>> os.sep
'/'

Use ToString() with this format:

12345.678901.ToString("0.0000"); // outputs 12345.6789
12345.0.ToString("0.0000"); // outputs 12345.0000

Put as much zero as necessary at the end of the format.

RUN: Can be many, and it is used in build process, e.g. install multiple libraries

CMD: Can only have 1, which is your execute start point (e.g. ["npm", "start"], ["node", "app.js"])

There is no Gacutil included in the .net 4.0 standard installation. They have moved the GAC too, from %Windir%\assembly to %Windir%\Microsoft.NET\Assembly.

They havent' even bothered adding a "special view" for the folder in Windows explorer, as they have for the .net 1.0/2.0 GAC.

Gacutil is part of the Windows SDK, so if you want to use it on your developement machine, just install the Windows SDK for your current platform. Then you will find it somewhere like this (depending on your SDK version):

C:\Program Files\Microsoft SDKs\Windows\v7.0A\bin\NETFX 4.0 Tools

There is a discussion on the new GAC here: .NET 4.0 has a new GAC, why?

If you want to install something in GAC on a production machine, you need to do it the "proper" way (gacutil was never meant as a tool for installing stuff on production servers, only as a development tool), with a Windows Installer, or with other tools. You can e.g. do it with PowerShell and the System.EnterpriseServices dll.

On a general note, and coming from several years of experience, I would personally strongly recommend against using GAC at all. Your application will always work if you deploy the DLL with each application in its bin folder as well. Yes, you will get multiple copies of the DLL on your server if you have e.g. multiple web apps on one server, but it's definitely worth the flexibility of being able to upgrade one application without breaking the others (by introducing an incompatible version of the shared DLL in the GAC).

Thats where asp.net puts dynamically compiled assemblies.

Try this:

Get-ChildItem -Path V:\Myfolder -Filter CopyForbuild.bat -Recurse | Where-Object { $_.Attributes -ne "Directory"}

You can rename your Conda env by just renaming the env folder. Here is the proof:

You can find your Conda env folder inside of C:\ProgramData\Anaconda3\envs or you can enter conda env list to see the list of conda envs and its location.

As per this answer over here: str='foo%20%5B12%5D' encodes foo [12]:

%20 is space
%5B is '['
and %5D is ']'

This is called percent encoding and is used in encoding special characters in the url parameter values.

EDIT By the way as I was reading https://developer.mozilla.org/en-US/docs/JavaScript/Reference/Global_Objects/encodeURI#Description, it just occurred to me why so many people make the same search. See the note on the bottom of the page:

Also note that if one wishes to follow the more recent RFC3986 for URL's, making square brackets reserved (for IPv6) and thus not encoded when forming something which could be part of a URL (such as a host), the following may help.

function fixedEncodeURI (str) {
    return encodeURI(str).replace(/%5B/g, '[').replace(/%5D/g, ']');
}

Hopefully this will help people sort out their problems when they stumble upon this question.

I just had a jaw-drop moment - Termux allows you to install NodeJS on an Android device!

It seems to work for a basic Websocket Speed Test I had on hand. The http served by it can be accessed both locally and on the network.

There is a medium post that explains the installation process

Basically: 1. Install termux 2. apt install nodejs 3. node it up!

One restriction I've run into - it seems the shared folders don't have the necessary permissions to install modules. It might just be a file permission thing. The private app storage works just fine.

When the local git projects are cloned in eclipse and are viewable in git perspective but not in package explorer (workspace), the following steps worked for me:

• Select the repository in git perspective
• Right click and select import projects

This is what I did. What I've done differently is use the same name and the new keyword on the "consuming" enum. Since the name of the enum is the same, you can just mindlessly use it and it will be right. Plus you get intellisense. You just have to manually take care when setting it up that the values are copied over from the base and keep them sync'ed. You can help that along with code comments. This is another reason why in the database when storing enum values I always store the string, not the value. Because if you are using automatically assigned increasing integer values those can change over time.

// Base Class for balls 
public class BaseBall
{
    // keep synced with subclasses!
    public enum Sizes
    {
        Small,
        Medium,
        Large
    }
}

public class VolleyBall : BaseBall
{
    // keep synced with base class!
    public new enum Sizes
    {
        Small = BaseBall.Sizes.Small,
        Medium = BaseBall.Sizes.Medium,
        Large = BaseBall.Sizes.Large,
        SmallMedium,
        MediumLarge,
        Ginormous
    }
}

Use scanf("%d",&rows) instead of scanf("%s",input)

This allow you to get direcly the integer value from stdin without need to convert to int.

If the user enter a string containing a non numeric characters then you have to clean your stdin before the next scanf("%d",&rows).

your code could look like this:

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

int clean_stdin()
{
    while (getchar()!='\n');
    return 1;
}

int main(void)  
{ 
    int rows =0;  
    char c;
    do
    {  
        printf("\nEnter an integer from 1 to 23: ");

    } while (((scanf("%d%c", &rows, &c)!=2 || c!='\n') && clean_stdin()) || rows<1 || rows>23);

    return 0;  
}

Explanation

1)

scanf("%d%c", &rows, &c)

This means expecting from the user input an integer and close to it a non numeric character.

Example1: If the user enter aaddk and then ENTER, the scanf will return 0. Nothing capted

Example2: If the user enter 45 and then ENTER, the scanf will return 2 (2 elements are capted). Here %d is capting 45 and %c is capting \n

Example3: If the user enter 45aaadd and then ENTER, the scanf will return 2 (2 elements are capted). Here %d is capting 45 and %c is capting a

2)

(scanf("%d%c", &rows, &c)!=2 || c!='\n')

In the example1: this condition is TRUE because scanf return 0 (!=2)

In the example2: this condition is FALSE because scanf return 2 and c == '\n'

In the example3: this condition is TRUE because scanf return 2 and c == 'a' (!='\n')

3)

((scanf("%d%c", &rows, &c)!=2 || c!='\n') && clean_stdin())

clean_stdin() is always TRUE because the function return always 1

In the example1: The (scanf("%d%c", &rows, &c)!=2 || c!='\n') is TRUE so the condition after the && should be checked so the clean_stdin() will be executed and the whole condition is TRUE

In the example2: The (scanf("%d%c", &rows, &c)!=2 || c!='\n') is FALSE so the condition after the && will not checked (because what ever its result is the whole condition will be FALSE ) so the clean_stdin() will not be executed and the whole condition is FALSE

In the example3: The (scanf("%d%c", &rows, &c)!=2 || c!='\n') is TRUE so the condition after the && should be checked so the clean_stdin() will be executed and the whole condition is TRUE

So you can remark that clean_stdin() will be executed only if the user enter a string containing non numeric character.

And this condition ((scanf("%d%c", &rows, &c)!=2 || c!='\n') && clean_stdin()) will return FALSE only if the user enter an integer and nothing else

And if the condition ((scanf("%d%c", &rows, &c)!=2 || c!='\n') && clean_stdin()) is FALSE and the integer is between and 1 and 23 then the while loop will break else the while loop will continue

To recap on the previous answers. If you have a list with [0,1,2] and another one with [3,4,5] and you want to merge them, so it becomes [0,1,2,3,4,5], you can either use chaining or extending and should know the differences to use it wisely for your needs.

Extending a list

Using the list classes extend method, you can do a copy of the elements from one list onto another. However this will cause extra memory usage, which should be fine in most cases, but might cause problems if you want to be memory efficient.

a = [0,1,2]
b = [3,4,5]
a.extend(b)
>>[0,1,2,3,4,5]

Chaining a list

Contrary you can use itertools.chain to wire many lists, which will return a so called iterator that can be used to iterate over the lists. This is more memory efficient as it is not copying elements over but just pointing to the next list.

import itertools
a = [0,1,2]
b = [3,4,5]
c = itertools.chain(a, b)

Make an iterator that returns elements from the first iterable until it is exhausted, then proceeds to the next iterable, until all of the iterables are exhausted. Used for treating consecutive sequences as a single sequence.

You can iterate over keys by calling map.keySet(), or iterate over the entries by calling map.entrySet(). Iterating over entries will probably be faster.

for (Map.Entry<String, List<String>> entry : map.entrySet()) {
    List<String> list = entry.getValue();
    // Do things with the list
}

If you want to ensure that you iterate over the keys in the same order you inserted them then use a LinkedHashMap.

By the way, I'd recommend changing the declared type of the map to <String, List<String>>. Always best to declare types in terms of the interface rather than the implementation.

Select Java editor settings for Intellij Select values for Tabsize, Indent & Continuation Intent (I choose 4,4 & 4)

Then Ctrl + Alt + L to format your file (or your selection).

<link href="https://fonts.googleapis.com/css?family=(any font of your 
choice)" rel="stylesheet" type="text/css">

To choose the font you can visit the link : https://fonts.google.com

Write the font name of your choice from the website excluding the brackets.

For example you chose Lobster as a font of your choice then,

<link href="https://fonts.googleapis.com/css?family=Lobster" rel="stylesheet" 
type="text/css">

Then you can use this normally as a font-family in your whole HTML/CSS file.

For example

Just ran into this. I'm getting over 6,000 records. Just decided I'd just do some paging. As in, I accept a page number in my MVC JsonResult endpoint, which is defaulted to 0 so it's not necessary, like so:

public JsonResult MyObjects(int pageNumber = 0)

Then instead of saying:

return Json(_repository.MyObjects.ToList(), JsonRequestBehavior.AllowGet);

I say:

return Json(_repository.MyObjects.OrderBy(obj => obj.ID).Skip(1000 * pageNumber).Take(1000).ToList(), JsonRequestBehavior.AllowGet);

It's very simple. Then, in JavaScript, instead of this:

function myAJAXCallback(items) {
    // Do stuff here
}

I instead say:

var pageNumber = 0;
function myAJAXCallback(items) {
    if(items.length == 1000)
        // Call same endpoint but add this to the end: '?pageNumber=' + ++pageNumber
    }
    // Do stuff here
}

And append your records to whatever you were doing with them in the first place. Or just wait until all the calls finish and cobble the results together.

I see this question so much! everywhere I look lacks the real answer.

The php.ini should be in the wp-admin directory, if it isn't just create it and then define whats needed, by default it should contain.

upload_max_filesize = 64M
post_max_size = 64M
max_execution_time = 300

Use LayoutParams (as explained already). However be careful which LayoutParams to choose. According to https://stackoverflow.com/a/11971553/3184778 "you need to use the one that relates to the PARENT of the view you're working on, not the actual view"

If for example the TextView is inside a TableRow, then you need to use TableRow.LayoutParams instead of RelativeLayout or LinearLayout

For applications such as games and embedded systems where memory and performance are both critical, float is usually the numeric type of choice as it is faster and half the size of a double. Integers used to be the weapon of choice, but floating point performance has overtaken integer in modern processors. Decimal is right out!

Use finish like this:

Intent i = new Intent(Main_Menu.this, NextActivity.class);
finish();  //Kill the activity from which you will go to next activity 
startActivity(i);

FLAG_ACTIVITY_NO_HISTORY you can use in case for the activity you want to finish. For exampe you are going from A-->B--C. You want to finish activity B when you go from B-->C so when you go from A-->B you can use this flag. When you go to some other activity this activity will be automatically finished.

To learn more on using Intent.FLAG_ACTIVITY_NO_HISTORY read: http://developer.android.com/reference/android/content/Intent.html#FLAG_ACTIVITY_NO_HISTORY

The problem is that you aren't correctly escaping the input string, try:

echo "\"member\":\"time\"" | grep -e "member\""

Alternatively, you can use unescaped double quotes within single quotes:

echo '"member":"time"' | grep -e 'member"'

It's a matter of preference which you find clearer, although the second approach prevents you from nesting your command within another set of single quotes (e.g. ssh 'cmd').

Declare Array: int[] arr;

Initialize Array: int[] arr = new int[10]; 10 represents the number of elements allowed in the array

Declare Multidimensional Array: int[][] arr;

Initialize Multidimensional Array: int[][] arr = new int[10][17]; 10 rows and 17 columns and 170 elements because 10 times 17 is 170.

Initializing an array means specifying the size of it.

You're going to have to rely on each individual's machine having the correct file associations. If you try and open the application from JavaScript/VBScript in a web page, the spawned application is either going to itself be sandboxed (meaning decreased permissions) or there are going to be lots of security prompts.

My suggestion is to look to SharePoint server for this one. This is something that we know they do and you can edit in place, but the question becomes how they manage to pull that off. My guess is direct integration with Office. Either way, this isn't something that the Internet is designed to do, because I'm assuming you want them to edit the original document and not simply create their own copy (which is what the default behavior of file:// would be.

So depending on you options, it might be possible to create a client side application that gets installed on all your client machines and then responds to a particular file handler that says go open this application on the file server. Then it wouldn't really matter who was doing it since all browsers would simply hand off the request to you. You would have to create your own handler like fileserver://.

Don't use in Browser

In the browser, use document.querySelect('[attribute-name]').

But if you're unit testing and your mocked dom has a flakey querySelector implementation, this will do the trick.

This is @kevinfahy's answer, just trimmed down to be a bit with ES6 fat arrow functions and by converting the HtmlCollection into an array at the cost of readability perhaps.

So it'll only work with an ES6 transpiler. Also, I'm not sure how performant it'll be with a lot of elements.

function getElementsWithAttribute(attribute) {
  return [].slice.call(document.getElementsByTagName('*'))
    .filter(elem => elem.getAttribute(attribute) !== null);
}

And here's a variant that will get an attribute with a specific value

function getElementsWithAttributeValue(attribute, value) {
  return [].slice.call(document.getElementsByTagName('*'))
    .filter(elem => elem.getAttribute(attribute) === value);
}

Here is the solution that best worked for me without attaching events to the container:

Certain HTML elements can have what is known as "focus", for example input elements. Those elements will also respond to the blur event, when they lose that focus.

To give any element the capacity to have focus, just make sure its tabindex attribute is set to anything other than -1. In regular HTML that would be by setting the tabindex attribute, but in React you have to use tabIndex (note the capital I).

You can also do it via JavaScript with element.setAttribute('tabindex',0)

This is what I was using it for, to make a custom DropDown menu.

var DropDownMenu = React.createClass({
    getInitialState: function(){
        return {
            expanded: false
        }
    },
    expand: function(){
        this.setState({expanded: true});
    },
    collapse: function(){
        this.setState({expanded: false});
    },
    render: function(){
        if(this.state.expanded){
            var dropdown = ...; //the dropdown content
        } else {
            var dropdown = undefined;
        }

        return (
            <div className="dropDownMenu" tabIndex="0" onBlur={ this.collapse } >
                <div className="currentValue" onClick={this.expand}>
                    {this.props.displayValue}
                </div>
                {dropdown}
            </div>
        );
    }
});

Others have answered your question perfectly, but I just thought I would throw out another way. It's always a good idea to separate HTML markup, CSS styling, and javascript code when possible. The cleanest way to hide something, with that in mind, is using a class. It allows the definition of "hide" to be defined in the CSS where it belongs. Using this method, you could later decide you want the ul to hide by scrolling up or fading away using CSS transition, all without changing your HTML or code. This is longer, but I feel it's a better overall solution.

Demo: http://jsfiddle.net/ThinkingStiff/RkQCF/

HTML:

<a id="showTags" href="#" title="Show Tags">Show All Tags</a>
<ul id="subforms" class="subforums hide"><li>one</li><li>two</li><li>three</li></ul>

CSS:

#subforms {
    overflow-x: visible; 
    overflow-y: visible;
}

.hide {
    display: none; 
}

Script:

document.getElementById( 'showTags' ).addEventListener( 'click', function () {
    document.getElementById( 'subforms' ).toggleClass( 'hide' );
}, false );

Element.prototype.toggleClass = function ( className ) {
    if( this.className.split( ' ' ).indexOf( className ) == -1 ) {
        this.className = ( this.className + ' ' + className ).trim();
    } else {
        this.className = this.className.replace( new RegExp( '(\\s|^)' + className + '(\\s|$)' ), ' ' ).trim();
    };
};

Maybe just try this simple script:

Result is:

CREATE SEQUENCE TABLE_PK_SEQ; 
CREATE OR REPLACE TRIGGER TR_SEQ_TABLE BEFORE INSERT ON TABLE FOR EACH ROW 

BEGIN
SELECT TABLE_PK_SEQ.NEXTVAL
INTO :new.PK
FROM dual;
END;

I tracked the solution down to Interface Builder's insistence that springs cannot be changed on a view that has the simulated screen elements turned on (status bar, etc.). Since the springs were off for the main view, that view could not change size and hence was scrolled down in its entirety when the in-call bar appeared.

Turning the simulated features off, then resizing the view and setting the springs correctly caused the animation to occur and my method to be called.

An extra problem in debugging this is that the simulator quits the app when the in-call status is toggled via the menu. Quit app = no debugger.

lappend <- function (lst, ...){

Bye.

You could use lodash method _.uniqWith, it is available in the current version of lodash 4.17.2.

Example:

var objects = [{ 'x': 1, 'y': 2 }, { 'x': 2, 'y': 1 }, { 'x': 1, 'y': 2 }];

_.uniqWith(objects, _.isEqual);
// => [{ 'x': 1, 'y': 2 }, { 'x': 2, 'y': 1 }]

More info: https://lodash.com/docs/#uniqWith

Edit the configuration and then in the box: Script path, select your .py file!

A slightly other way of iterating through each column of each line of a CSV-file would be

$path = "d:\scratch\export.csv"
$csv = Import-Csv -path $path

foreach($line in $csv)
{ 
    $properties = $line | Get-Member -MemberType Properties
    for($i=0; $i -lt $properties.Count;$i++)
    {
        $column = $properties[$i]
        $columnvalue = $line | Select -ExpandProperty $column.Name

        # doSomething $column.Name $columnvalue 
        # doSomething $i $columnvalue 
    }
} 

so you have the choice: you can use either $column.Name to get the name of the column, or $i to get the number of the column

Look at strtok(). strtok() is not a re-entrant function.

strtok_r() is the re-entrant version of strtok(). Here's an example program from the manual:

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

   int main(int argc, char *argv[])
   {
       char *str1, *str2, *token, *subtoken;
       char *saveptr1, *saveptr2;
       int j;

       if (argc != 4) {
           fprintf(stderr, "Usage: %s string delim subdelim\n",argv[0]);
           exit(EXIT_FAILURE);
       }

       for (j = 1, str1 = argv[1]; ; j++, str1 = NULL) {
           token = strtok_r(str1, argv[2], &saveptr1);
           if (token == NULL)
               break;
           printf("%d: %s\n", j, token);

           for (str2 = token; ; str2 = NULL) {
               subtoken = strtok_r(str2, argv[3], &saveptr2);
               if (subtoken == NULL)
                   break;
               printf(" --> %s\n", subtoken);
           }
       }

       exit(EXIT_SUCCESS);
   }

Sample run which operates on subtokens which was obtained from the previous token based on a different delimiter:

$ ./a.out hello:word:bye=abc:def:ghi = :

1: hello:word:bye
 --> hello
 --> word
 --> bye
2: abc:def:ghi
 --> abc
 --> def
 --> ghi

Swift 5.3

I think this is very elegant. Kudos at Paul Hudson of "Hacking with Swift" for this solution:

@available (macOS 10.15, * )
extension String {
    subscript(idx: Int) -> String {
        String(self[index(startIndex, offsetBy: idx)])
    }
}

Then to get one character out of the String you simply do:

var string = "Hello, world!"

var firstChar = string[0] // No error, returns "H" as a String

To load data from text file or csv file the command is

load data local infile 'file-name.csv'
into table table-name
fields terminated by '' enclosed by '' lines terminated by '\n' (column-name);

In above command, in my case there is only one column to be loaded so there is no "terminated by" and "enclosed by" so I kept it empty else programmer can enter the separating character . for e.g . ,(comma) or " or ; or any thing.

**for people who are using mysql version 5 and above **

Before loading the file into mysql must ensure that below tow line are added in side etc/mysql/my.cnf

to edit my.cnf command is

sudo vi /etc/mysql/my.cnf

[mysqld]  
local-infile

[mysql]  
local-infile  

I wanted to a way to compare the different solutions that made it easy to turn the knobs.

First I generated my data:

import random

N = 16 * 1024
x = range(N)
random.shuffle(x)
y = random.sample(range(N), N / 10)

Then I defined my functions:

def list_set(value_list, index_list):
    index_list = set(index_list)
    result = [value for index, value in enumerate(value_list) if index not in index_list]
    return result

def list_del(value_list, index_list):
    for index in sorted(index_list, reverse=True):
        del(value_list[index])

def list_pop(value_list, index_list):
    for index in sorted(index_list, reverse=True):
        value_list.pop(index)

Then I used timeit to compare the solutions:

import timeit
from collections import OrderedDict

M = 1000
setup = 'from __main__ import x, y, list_set, list_del, list_pop'
statement_dict = OrderedDict([
    ('overhead',  'a = x[:]'),
    ('set', 'a = x[:]; list_set(a, y)'),
    ('del', 'a = x[:]; list_del(a, y)'),
    ('pop', 'a = x[:]; list_pop(a, y)'),
])

overhead = None
result_dict = OrderedDict()
for name, statement in statement_dict.iteritems():
    result = timeit.timeit(statement, number=M, setup=setup)
    if overhead is None:
        overhead = result
    else:
        result = result - overhead
        result_dict[name] = result

for name, result in result_dict.iteritems():
    print "%s = %7.3f" % (name, result)

Output

set =   1.711
del =   3.450
pop =   3.618

So the generator with the indices in a set was the winner. And del is slightly faster then pop.

If for some reason it's still not working. First option for Laravel The second option for any application

FIRST OPTION:

1. As in the example above, we create middleware

    php artisan make:middleware Cors
   

2. Add the following code to app/Http/Middleware/Cors.php:

    public function handle($request, Closure $next) 
    {
        return $next($request)
            ->header('Access-Control-Allow-Origin', '*')
            ->header('Access-Control-Allow-Methods', 'GET, POST, PUT, PATCH, DELETE, OPTIONS')
            ->header('Access-Control-Allow-Headers', 'Authorization,Accept,Origin,DNT,X-CustomHeader,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Content-Range,Range'); 
    }
   

Look closely, the amount of data in the header ->header('Access-Control-Allow-Headers',

3. Step three, add middleware to $routeMiddleware array in app/Http/Kernel.php

    protected $routeMiddleware = [
        ....
        'cors' => \App\Http\Middleware\Cors::class,
    ];
   

SECOND OPTION:

1. Open the nginx.conf settings for your domain.

    sudo nano /etc/nginx/sites-enabled/your-domain.conf
   

2. Inside the server settings server { listen 80; .... } please add the following code:

    add_header 'Access-Control-Allow-Origin' '*';
    add_header 'Access-Control-Allow-Credentials' 'true';
    add_header 'Access-Control-Allow-Headers' 'Authorization,Accept,Origin,DNT,X-CustomHeader,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Content-Range,Range';
    add_header 'Access-Control-Allow-Methods' 'GET,POST,OPTIONS,PUT,DELETE,PATCH';
   

If you're using cygwin or some minimal shell that lacks killall you can just use this script:

killall.sh - Kill by process name.

#/bin/bash
ps -W | grep "$1" | awk '{print $1}' | xargs kill --

Usage:

$ killall <process name>

As of now (October 2017) Google has implemented a specific property to handle the zooming/scrolling, called gestureHandling. Its purpose is to handle mobile devices operation, but it modifies the behaviour for desktop browsers as well. Here it is from official documentation:

function initMap() {
  var locationRio = {lat: -22.915, lng: -43.197};
  var map = new google.maps.Map(document.getElementById('map'), {
    zoom: 13,
    center: locationRio,
    gestureHandling: 'none'
});

The available values for gestureHandling are:

• 'greedy': The map always pans (up or down, left or right) when the user swipes (drags on) the screen. In other words, both a one-finger swipe and a two-finger swipe cause the map to pan.
• 'cooperative': The user must swipe with one finger to scroll the page and two fingers to pan the map. If the user swipes the map with one finger, an overlay appears on the map, with a prompt telling the user to use two fingers to move the map. On desktop applications, users can zoom or pan the map by scrolling while pressing a modifier key (the ctrl or ? key).
• 'none': This option disables panning and pinching on the map for mobile devices, and dragging of the map on desktop devices.
• 'auto' (default): Depending on whether the page is scrollable, the Google Maps JavaScript API sets the gestureHandling property to either 'cooperative' or 'greedy'

In short, you can easily force the setting to "always zoomable" ('greedy'), "never zoomable" ('none'), or "user must press CRTL/? to enable zoom" ('cooperative').

If you get an exception for : Invalid column type

Please use getNamedParameterJdbcTemplate() instead of getJdbcTemplate()

 List<Foo> foo = getNamedParameterJdbcTemplate().query("SELECT * FROM foo WHERE a IN (:ids)",parameters,
 getRowMapper());

Note that the second two arguments are swapped around.

Blast from the past but I think I found an easy answer to this. The following worked for me. I think it's the equivalent of selecting the cell hitting F2 and then hitting enter, which makes Excel recognize the text as a date.

Columns("A").Select
Selection.Value = Selection.Value

orclpdb is the name of pluggable database which may be different based on the individual.

Richard Schneider is right. use code below to fetch data from site which is not utf8 charset will get wrong string.

It is important to know not only the types but the mapping of these types to the database types, too:

Edit: Here's a plugin I authored that extends the jQuery UI Dialog to include closing when clicking outside plus other features: https://github.com/jasonday/jQuery-UI-Dialog-extended

Here are 3 methods to close a jquery UI dialog when clicking outside popin:

If the dialog is modal/has background overlay: http://jsfiddle.net/jasonday/6FGqN/

jQuery(document).ready(function() {
    jQuery("#dialog").dialog({
        bgiframe: true,
        autoOpen: false,
        height: 100,
        modal: true,
        open: function() {
            jQuery('.ui-widget-overlay').bind('click', function() {
                jQuery('#dialog').dialog('close');
            })
        }
    });
}); 

If dialog is non-modal Method 1: http://jsfiddle.net/jasonday/xpkFf/

// Close Pop-in If the user clicks anywhere else on the page
jQuery('body')
    .bind('click', function(e) {
        if(jQuery('#dialog').dialog('isOpen')
            && !jQuery(e.target).is('.ui-dialog, a')
            && !jQuery(e.target).closest('.ui-dialog').length
        ) {
            jQuery('#dialog').dialog('close');
        }
    });

Non-Modal dialog Method 2: http://jsfiddle.net/jasonday/eccKr/

$(function() {
    $('#dialog').dialog({
        autoOpen: false, 
        minHeight: 100,
        width: 342,
        draggable: true,
        resizable: false,
        modal: false,
        closeText: 'Close',
        open: function() {
            closedialog = 1;
            $(document).bind('click', overlayclickclose); },
        focus: function() { 
            closedialog = 0; },
        close: function() { 
            $(document).unbind('click'); }
    });

    $('#linkID').click(function() {
        $('#dialog').dialog('open');
        closedialog = 0;
    });

    var closedialog;

    function overlayclickclose() {
        if (closedialog) {
            $('#dialog').dialog('close');
        }
        //set to one because click on dialog box sets to zero
        closedialog = 1;
    }
});

You could use a simple regular expression to assert that the id only contains allowed characters, like so:

if(id.match(/^[0-9a-zA-Z]{1,16}$/)){
    //The id is fine
}
else{
    //The id is illegal
}

My example allows only alphanumerical characters, and strings of length 1 to 16, you should change it to match the type of ids that you use.

By the way, at line 6, the value property is missing a pair of quotes, an easy mistake to make when you quote on two levels.

I can't see your actual data flow, depending on context this check may not at all be needed, or it may not be enough. In order to make a proper security review we would need more information.

In general, about built in escape or sanitize functions, don't trust them blindly. You need to know exactly what they do, and you need to establish that that is actually what you need. If it is not what you need, the code your own, most of the time a simple whitelisting regex like the one I gave you works just fine.

As an alternative to using UsedRange or providing an explicit range address, the AutoFilter.Range property can also specify the affected range.

ActiveSheet.AutoFilter.Range.Offset(1,0).Rows.SpecialCells(xlCellTypeVisible).Delete(xlShiftUp)

As used here, Offset causes the first row after the AutoFilter range to also be deleted. In order to avoid that, I would try using .Resize() after .Offset().

For just one run (from the unix shell prompt):

$ PORT=1234 node app.js

More permanently:

$ export PORT=1234
$ node app.js

In Windows:

set PORT=1234

In Windows PowerShell:

$env:PORT = 1234

while 1:
    root.update()

... is (very!) roughly similar to:

root.mainloop()

The difference is, mainloop is the correct way to code and the infinite loop is subtly incorrect. I suspect, though, that the vast majority of the time, either will work. It's just that mainloop is a much cleaner solution. After all, calling mainloop is essentially this under the covers:

while the_window_has_not_been_destroyed():
    wait_until_the_event_queue_is_not_empty()
    event = event_queue.pop()
    event.handle()

... which, as you can see, isn't much different than your own while loop. So, why create your own infinite loop when tkinter already has one you can use?

Put in the simplest terms possible: always call mainloop as the last logical line of code in your program. That's how Tkinter was designed to be used.

This will open a second cmd.exe window. If you want it to go away, replace the /K with /C.

Obviously, replace new_file_loc with whatever your new file location will be.

@echo off
for /F %%i in ('dir /B /O:-D *.txt') do (
    call :open "%%i"
    exit /B 0
)
:open
    start "window title" "cmd /K copy %~1 new_file_loc"
exit /B 0

The 'Answer' didn't work for me some reasons. So here is what I ended up doing:

map.fitBounds(bounds);//works!

I will share my experience with this problem. I was going crazy because of this, but I found out that the problem was a bug with Eclipse itself, rather than my code: In eclipse, unable to reference an android library project in another android project

So, if you have the Android Support Library in your C: drive and your project in the D: drive on your computer, Eclipse won't function correctly and won't know where the Android Support Library is (green tick turns into red cross). To solve this, you need to move both projects onto the same hard drive.

I have also encounter the same issue. One possible solution is to go to Xcode -> Preferences -> Accounts and from the left menu select on App ID then click on the View Details and tap on the refresh button. while reloading you will get following error

The selected team's agent, 'ADMIN NAME' must agree to the latest Program License Agreement.

If you will not get above error, Following solution will not work.

It means that you need to login into the developer account using Admin login and accept that latest agreement. Then you will be able to upload binary on the app store.

Set the aaSorting option to an empty array. It will disable initial sorting, whilst still allowing manual sorting when you click on a column.

"aaSorting": []

The aaSorting array should contain an array for each column to be sorted initially containing the column's index and a direction string ('asc' or 'desc').

You're looking for the OpenFileDialog class.

For example:

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

Yes, you can configure the Spring servlet context xml file to define your beans (i.e., classes), so that it can do the automatic injection for you. However, do note, that you have to do other configurations to have Spring up and running and the best way to do that, is to follow a tutorial ground up.

Once you have your Spring configured probably, you can do the following in your Spring servlet context xml file for Example 1 above to work (please replace the package name of com.movies to what the true package name is and if this is a 3rd party class, then be sure that the appropriate jar file is on the classpath) :

<beans:bean id="movieFinder" class="com.movies.MovieFinder" />

or if the MovieFinder class has a constructor with a primitive value, then you could something like this,

<beans:bean id="movieFinder" class="com.movies.MovieFinder" >
    <beans:constructor-arg value="100" />
</beans:bean>

or if the MovieFinder class has a constructor expecting another class, then you could do something like this,

<beans:bean id="movieFinder" class="com.movies.MovieFinder" >
    <beans:constructor-arg ref="otherBeanRef" />
</beans:bean>

...where 'otherBeanRef' is another bean that has a reference to the expected class.

If you just want the unix timestamp, create an extension:

extension Date {
    func currentTimeMillis() -> Int64 {
        return Int64(self.timeIntervalSince1970 * 1000)
    }
}

Then you can use it just like in other programming languages:

let timestamp = Date().currentTimeMillis()

Easy Peasy:

StringBuilder sb= new StringBuilder();
for(Entry<String,String> entry : map.entrySet()) {
        sb.append(entry.getKey() + "_" + entry.getValue() + "|");
}
String requiredString = sb.substring(0, sb.length() - 1);

TreeMap and TreeSet will give you an iteration over the contents in sorted order. Or you could use an ArrayList and use Collections.sort() to sort it. All those classes are in java.util

Turns out that the problem was with face that the script was running from a cPanel "email piped to script", so was running as the user, so is was a user problem, but was not affecting the web server at all.

The cause for the user not being able to access the /etc/pki directory was due to them only having jailed ssh access. Once I granted full access, it all worked fine.

Thanks for the info though, Remi.

for swift 2.2:

let today = NSDate()
let tomorrow = NSCalendar.currentCalendar().dateByAddingUnit(
        .Day,
        value: 1,
        toDate: today,
        options: NSCalendarOptions.MatchStrictly)

Hope this helps someone!

First a pointed to the string "Dog". Then you changed the variable a to point at a new string "Dog eats treats". You didn't actually mutate the string "Dog". Strings are immutable, variables can point at whatever they want.

For me I had a AdoptOpenJDK 8 installed, instead of SE JDK 8. For which it was not able to recognize JAVA_HOME or mvn commands.

Check your java_home /usr/libexec/java_home -V and use JAVA SE SDK if it is different.

Then follow the above steps to install maven and check again

If you create an image tag and add it to the DOM, either its onload or onerror event should fire. If onerror fires, the image doesn't exist on the server.

In case you don't want to set fixed width to anything

The solution below allows you to have table cell content that is long, but must not affect the width of the parent table, nor the height of the parent row. For example where you want to have a table with width:100% that still applies auto-size feature to all other cells. Useful in data grids with "Notes" or "Comment" column or something.

Add these 3 rules to your CSS:

.text-overflow-dynamic-container {
    position: relative;
    max-width: 100%;
    padding: 0 !important;
    display: -webkit-flex;
    display: -moz-flex;
    display: flex;
    vertical-align: text-bottom !important;
}
.text-overflow-dynamic-ellipsis {
    position: absolute;
    white-space: nowrap;
    overflow-y: visible;
    overflow-x: hidden;
    text-overflow: ellipsis;
    -ms-text-overflow: ellipsis;
    -o-text-overflow: ellipsis;
    max-width: 100%;
    min-width: 0;
    width:100%;
    top: 0;
    left: 0;
}
.text-overflow-dynamic-container:after,
.text-overflow-dynamic-ellipsis:after {
    content: '-';
    display: inline;
    visibility: hidden;
    width: 0;
}

Format HTML like this in any table cell you want dynamic text overflow:

<td>
  <span class="text-overflow-dynamic-container">
    <span class="text-overflow-dynamic-ellipsis" title="...your text again for usability...">
      //...your long text here...
    </span>
  </span>
</td>

Additionally apply desired min-width (or none at all) to the table cell.

Of course the fiddle: https://jsfiddle.net/9wycg99v/23/

Passing the dataframes to concat in a dictionary, results in a multi-index dataframe from which you can easily delete the duplicates, which results in a multi-index dataframe with the differences between the dataframes:

import sys
if sys.version_info[0] < 3:
    from StringIO import StringIO
else:
    from io import StringIO
import pandas as pd

DF1 = StringIO("""Date       Fruit  Num  Color 
2013-11-24 Banana 22.1 Yellow
2013-11-24 Orange  8.6 Orange
2013-11-24 Apple   7.6 Green
2013-11-24 Celery 10.2 Green
""")
DF2 = StringIO("""Date       Fruit  Num  Color 
2013-11-24 Banana 22.1 Yellow
2013-11-24 Orange  8.6 Orange
2013-11-24 Apple   7.6 Green
2013-11-24 Celery 10.2 Green
2013-11-25 Apple  22.1 Red
2013-11-25 Orange  8.6 Orange""")


df1 = pd.read_table(DF1, sep='\s+')
df2 = pd.read_table(DF2, sep='\s+')
#%%
dfs_dictionary = {'DF1':df1,'DF2':df2}
df=pd.concat(dfs_dictionary)
df.drop_duplicates(keep=False)

Result:

             Date   Fruit   Num   Color
DF2 4  2013-11-25   Apple  22.1     Red
    5  2013-11-25  Orange   8.6  Orange

After trying out all different solutions, the following method is the most elegant one. Change the color in the following delegate method:

- (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath {
    if (...){
        cell.backgroundColor = [UIColor blueColor];
    } else {
        cell.backgroundColor = [UIColor whiteColor];
    }
}

I found an easy way to get the dictionary value, and its name as well! I'm not sure yet about reading it back, I'm going to continue to do research and see if I can figure that out.

Here is the code:

your_dict = {'one': 1, 'two': 2}

variables = [var for var in dir() if var[0:2] != "__" and var[-1:-2] != "__"]

file = open("your_file","w")
for var in variables:
     if isinstance(locals()[var], dict):
          file.write(str(var) + " = " + str(locals()[var]) + "\n")
file.close()

Only problem here is this will output every dictionary in your namespace to the file, maybe you can sort them out by values? locals()[var] == your_dict for reference.

You can also remove if isinstance(locals()[var], dict): to output EVERY variable in your namespace, regardless of type. Your output looks exactly like your decleration your_dict = {'one': 1, 'two': 2}.

Hopefully this gets you one step closer! I'll make an edit if I can figure out how to read them back into the namespace :)

---EDIT---

Got it! I've added a few variables (and variable types) for proof of concept. Here is what my "testfile.txt" looks like:

string_test = Hello World
integer_test = 42
your_dict = {'one': 1, 'two': 2}

And here is the code the processes it:

import ast

file = open("testfile.txt", "r")
data = file.readlines()
file.close()

for line in data:
    var_name, var_val = line.split(" = ")
    for possible_num_types in range(3):  # Range is the == number of types we will try casting to
        try:
            var_val = int(var_val)
            break
        except (TypeError, ValueError):
            try:
                var_val = ast.literal_eval(var_val)
                break
            except (TypeError, ValueError, SyntaxError):
                var_val = str(var_val).replace("\n","")
                break
    locals()[var_name] = var_val


print("string_test =", string_test, " :  Type =", type(string_test))
print("integer_test =", integer_test, " :  Type =", type(integer_test))
print("your_dict =", your_dict, " :  Type =", type(your_dict))

This is what that outputs:

string_test = Hello World  :  Type = <class 'str'>
integer_test = 42  :  Type = <class 'int'>
your_dict = {'two': 2, 'one': 1}  :  Type = <class 'dict'>

I really don't like how the casting here works, the try-except block is bulky and ugly. Even worse, you cannot accept just any type! You have to know what you are expecting to take in. This wouldn't be nearly as bad if you only cared about dictionaries, but I really wanted something a bit more universal.

If anybody knows how to better cast these input vars I would LOVE to hear about it!

Regardless, this should still get you there :D I hope I've helped out!

Its an injector error. You may have use lots of JavaScript files so the injector may be missing.

Some are here:

var app = angular.module('app', 
    ['ngSanitize', 'ui.router', 'pascalprecht.translate', 'ngResource', 
     'ngMaterial', 'angularMoment','md.data.table', 'angularFileUpload', 
     'ngMessages', 'ui.utils.masks', 'angular-sortable-view',          
     'mdPickers','ngDraggable','as.sortable', 'ngAnimate', 'ngTouch']
);

Please check the injector you need to insert in your app.js

You can get single file EXE after build the console application

your Application folder - > bin folder -> there will have lot of files there is need 2 files must and other referenced dlls

1. IMG_PDF_CONVERSION [this is my application name, take your application name]
2. IMG_PDF_CONVERSION.exe [this is supporting configure file]
3. your refered dll's

then you can move that 3(exe, configure file, refered dll's) dll to any folder that's it

if you click on 1st IMG_PDF_CONVERSION it will execute the application cool way

any calcification please ask your queries.

we can do it in more easy way like by adding a function on button and on click we call that function for append.

<div id="Content">
<button id="Add" onclick="append();">Add Text</button>
</div> 
<script type="text/javascript">
function append()
{
$('<p>Text</p>').appendTo('#Content');
}
</script>

There is a Python 2 implementation by odiak.

Try this for WPF

StreamResourceInfo sri = Application.GetResourceStream(new Uri("pack://application:,,,/WpfGifImage001;Component/Images/Progess_Green.gif"));
picBox1.Image = System.Drawing.Image.FromStream(sri.Stream);

Unique Key :

1. More than one value can be null.
2. No two tuples can have same values in unique key.
3. One or more unique keys can be combined to form a primary key, but not vice versa.

Primary Key

1. Can contain more than one unique keys.
2. Uniquely represents a tuple.

You can see for yourself which is better between - List Comprehension and the Map Function

(List Comprehension takes lesser time to process 1 million records when compared to a map function)

Hope it helps! Good Luck :)

Don't forget that you can also use HTML to detect IE8.

<!--[if IE 8]>
<script type="text/javascript">
    ie = 8;
</script>
<![endif]-->

Having that before all your scripts will let you just check the "ie" variable or whatever.

Are you creating a very large table (hundreds of rows and columns)? If so, table-layout: fixed; is a good idea, as the browser only needs to read the first row in order to compute and render the entire table, so it loads faster.

But if not, I would suggest dumping table-layout: fixed; and changing your css as follows:

table th, table td{
border: 1px solid #000;
width:20px;  //or something similar   
}

table td.wideRow, table th.wideRow{
width: 300px;
}

Can you show code which you use for setting date object? Anyway< you can use this code for intialisation of date:

new SimpleDateFormat("yyyy-MM-dd hh:mm:ss").parse("2011-01-01 00:00:00")

I queried Google for the usage of the different methods on GitHub. This is done by running a Google search query for each method and limiting the query to the github.com domain and the .cs file extension by using the query "site:github.com file:cs ..."

It seems that the First* methods are more commonly used than the Single* methods.

| Method               | Results |
|----------------------|---------|
| FirstAsync           |     315 |
| SingleAsync          |     166 |
| FirstOrDefaultAsync  |     357 |
| SingleOrDefaultAsync |     237 |
| FirstOrDefault       |   17400 |
| SingleOrDefault      |    2950 |

If the image is part of the layout it might be "View.VISIBLE" but that doesn't mean it's within the confines of the visible screen. If that's what you're after; this will work:

Rect scrollBounds = new Rect();
scrollView.getHitRect(scrollBounds);
if (imageView.getLocalVisibleRect(scrollBounds)) {
    // imageView is within the visible window
} else {
    // imageView is not within the visible window
}

Lodash can contribute a bug chunk of code to your bundle depending on how you import from it. For example:

// includes the entire package (very large)
import * as _ from 'lodash';

// depending on your buildchain, may still include the entire package
import { flatten } from 'lodash';

// imports only the code needed for `flatten`
import flatten from 'lodash-es/flatten'

Personally I still wanted smaller footprints from my utility functions. E.g. flatten can contribute up to 1.2K to your bundle, after minimization. So I've been building up a collection of simplified lodash functions. My implementation of flatten contributes around 50 bytes. You can check it out here to see if it works for you: https://github.com/simontonsoftware/micro-dash

http://www.gnu.org/software/hello/manual/libc/Variable-Arguments-Output.html gives the following example to print to stderr. You can modify it to use your log function instead:

 #include <stdio.h>
 #include <stdarg.h>

 void
 eprintf (const char *template, ...)
 {
   va_list ap;
   extern char *program_invocation_short_name;

   fprintf (stderr, "%s: ", program_invocation_short_name);
   va_start (ap, template);
   vfprintf (stderr, template, ap);
   va_end (ap);
 }

Instead of vfprintf you will need to use vsprintf where you need to provide an adequate buffer to print into.

This error occurs if you are using the wrong path.

For e.g:

I'm using ubuntu system and my project folder name is 'myproject'

Suppose I have myproject/public/report directory exist and want to create a new folder called orders

Then I need a whole path where my project exists. You can get the path by PWD command

So my root path will be = '/home/htdocs/myproject/'

$dir = '/home/htdocs/myproject/public/report/Orders';

if (!is_dir($dir)) {
   mkdir($dir, 0775, true);
}

It will work for you !! Enjoy !!

Change your main to:

public static void main(String[] args) {
    EchoServer echoServer = new EchoServer();
    echoServer.listen();
}

When you declare Object EchoServer0; you have a few mistakes.

1. EchoServer0 is of type Object, therefore it doesn't have the method listen().
2. You will also need to create an instance of it with new.
3. Another problem, this is only regarding naming conventions, you should call your variables starting by lower case letters, echoServer0 instead of EchoServer0. Uppercase names are usually for class names.
4. You should not create a variable with the same name as its class. It is confusing.

better to used refresh migrate

You may rollback & re-migrate a limited number of migrations by providing the step option to the refresh command. For example, the following command will rollback & re-migrate the last two migrations:

php artisan migrate:refresh --step=2

otherwise used rollback migrate

You may rollback a limited number of migrations by providing the step option to the rollback command. For example, the following command will rollback the last three migrations:

php artisan migrate:rollback --step=3

The following is not exactly the same but similar, I was searching for a snippet to add a call to the interface method, but found this question, so I decided to add this snippet for those who were searching for it like me and found this question:

 public class MyClass
 {
        //... class code goes here

        public interface DataLoadFinishedListener {
            public void onDataLoadFinishedListener(int data_type);
        }

        private DataLoadFinishedListener m_lDataLoadFinished;

        public void setDataLoadFinishedListener(DataLoadFinishedListener dlf){
            this.m_lDataLoadFinished = dlf;
        }



        private void someOtherMethodOfMyClass()
        {
            m_lDataLoadFinished.onDataLoadFinishedListener(1);
        }    
    }

Usage is as follows:

myClassObj.setDataLoadFinishedListener(new MyClass.DataLoadFinishedListener() {
            @Override
            public void onDataLoadFinishedListener(int data_type) {
                }
            });

It declares an anonymous function, then calls it:

You should remove the unwanted one from the manifest

works in rails 4.1 and support symbols without quotes {:a => 'b'}

just add this to initializers folder:

class String
  def to_hash_object
    JSON.parse(self.gsub(/:([a-zA-z]+)/,'"\\1"').gsub('=>', ': ')).symbolize_keys
  end
end

For those who want to use Python, here's a simple routine that removes parenthesized substrings, including those with nested parentheses. Okay, it's not a regex, but it'll do the job!

def remove_nested_parens(input_str):
    """Returns a copy of 'input_str' with any parenthesized text removed. Nested parentheses are handled."""
    result = ''
    paren_level = 0
    for ch in input_str:
        if ch == '(':
            paren_level += 1
        elif (ch == ')') and paren_level:
            paren_level -= 1
        elif not paren_level:
            result += ch
    return result

remove_nested_parens('example_(extra(qualifier)_text)_test(more_parens).ext')

aString = "hello world"
aString.startswith("hello")

Use fileReader.readAsDataURL( fileObject ), this will encode it to base64, which you can safely upload to your server.

Java does not check consistency in a strict sense, only notifies you if it runs into serious trouble. Also it does not give you much information from the error.

I was puzzled with what's happening in my sorter and made a strict consistencyChecker, maybe this will help you:

To clarify a point in Thomas' excellent answer, it should be mentioned that append() is thread safe.

This is because there is no concern that data being read will be in the same place once we go to write to it. The append() operation does not read data, it only writes data to the list.

I find both YAML and JSON to be very effective. The only two things that really dictate when one is used over the other for me is one, what the language is used most popularly with. For example, if I'm using Java, Javascript, I'll use JSON. For Java, I'll use their own objects, which are pretty much JSON but lacking in some features, and convert it to JSON if I need to or make it in JSON in the first place. I do that because that's a common thing in Java and makes it easier for other Java developers to modify my code. The second thing is whether I'm using it for the program to remember attributes, or if the program is receiving instructions in the form of a config file, in this case I'll use YAML, because it's very easily human read, has nice looking syntax, and is very easy to modify, even if you have no idea how YAML works. Then, the program will read it and convert it to JSON, or whatever is preferred for that language.

In the end, it honestly doesn't matter. Both JSON and YAML are easily read by any experienced programmer.

Use the same DBContext object throughout the transaction.

Choose your poison - if you can't change the type of the property to be nullable then you're going to have to use a "magic" value to represent NULL. Guid.Empty seems as good as any unless you have some specific reason for not wanting to use it. A second choice would be Guid.Parse("ffffffff-ffff-ffff-ffff-ffffffffffff") but that's a lot uglier IMHO.

Lets assume you want a data frame with the following schema:

root
 |-- k: string (nullable = true)
 |-- v: integer (nullable = false)

You simply define schema for a data frame and use empty RDD[Row]:

import org.apache.spark.sql.types.{
    StructType, StructField, StringType, IntegerType}
import org.apache.spark.sql.Row

val schema = StructType(
    StructField("k", StringType, true) ::
    StructField("v", IntegerType, false) :: Nil)

// Spark < 2.0
// sqlContext.createDataFrame(sc.emptyRDD[Row], schema) 
spark.createDataFrame(sc.emptyRDD[Row], schema)

PySpark equivalent is almost identical:

from pyspark.sql.types import StructType, StructField, IntegerType, StringType

schema = StructType([
    StructField("k", StringType(), True), StructField("v", IntegerType(), False)
])

# or df = sc.parallelize([]).toDF(schema)

# Spark < 2.0 
# sqlContext.createDataFrame([], schema)
df = spark.createDataFrame([], schema)

Using implicit encoders (Scala only) with Product types like Tuple:

import spark.implicits._

Seq.empty[(String, Int)].toDF("k", "v")

or case class:

case class KV(k: String, v: Int)

Seq.empty[KV].toDF

or

spark.emptyDataset[KV].toDF

Adding the following line into the form worked for me:

<%= hidden_field_tag :authenticity_token, form_authenticity_token %>

As already stated by Jason Cohen, the Java Language Specification defines what a legal identifier is in section 3.8:

"An identifier is an unlimited-length sequence of Java letters and Java digits, the first of which must be a Java letter. [...] A 'Java letter' is a character for which the method Character.isJavaIdentifierStart(int) returns true. A 'Java letter-or-digit' is a character for which the method Character.isJavaIdentifierPart(int) returns true."

This hopefully answers your second question. Regarding your first question; I've been taught both by teachers and (as far as I can remember) Java compilers that a Java class name should be an identifier that begins with a capital letter A-Z, but I can't find any reliable source on this. When trying it out with OpenJDK there are no warnings when beginning class names with lower-case letters or even a $-sign. When using a $-sign, you do have to escape it if you compile from a bash shell, however.

My solution is:

import os
print(os.path.dirname(os.path.abspath(__file__)))

Iterate over the Array. First initialize the maximum value to the first element of the array and then for each element optimize it if the element under consideration is greater.

Looks like this issue can be reproduced while folowing mentioned tutorial on unix machines. Also noticed that author uses TC 8.0.33
Win (and OSX) do not have such issue, at least on my env:

Server version:        Apache Tomcat/8.5.4
Server built:          Jul 6 2016 08:43:30 UTC
Server number:         8.5.4.0
OS Name:               Windows 8.1
OS Version:            6.3
Architecture:          amd64
Java Home:             C:\TOOLS\jdk1.8.0_101\jre
JVM Version:           1.8.0_101-b13
JVM Vendor:            Oracle Corporation
CATALINA_BASE:         C:\TOOLS\tomcat\apache-tomcat-8.5.4
CATALINA_HOME:         C:\TOOLS\tomcat\apache-tomcat-8.5.4

After tomcat-users.xml is modified by adding role and user Tomcat Web Application Manager can be accessed on Tomcat/8.5.4.

Maybe this could work:

import __init__ as lib

Try this

package main

import "fmt"
import "strconv"

func FloatToString(input_num float64) string {
    // to convert a float number to a string
    return strconv.FormatFloat(input_num, 'f', 6, 64)
}

func main() {
    fmt.Println(FloatToString(21312421.213123))
}

If you just want as many digits precision as possible, then the special precision -1 uses the smallest number of digits necessary such that ParseFloat will return f exactly. Eg

strconv.FormatFloat(input_num, 'f', -1, 64)

Personally I find fmt easier to use. (Playground link)

fmt.Printf("x = %.6f\n", 21312421.213123)

Or if you just want to convert the string

fmt.Sprintf("%.6f", 21312421.213123)

You can do something like:

s = np.random.normal(2, 3, 1000)
import matplotlib.pyplot as plt
count, bins, ignored = plt.hist(s, 30, density=True)
plt.plot(bins, 1/(3 * np.sqrt(2 * np.pi)) * np.exp( - (bins - 2)**2 / (2 * 3**2) ), 
linewidth=2, color='r')
plt.show()

This error can be due to many many things.

The key here seems the hint about error reading. I see you are working on a flash drive or something similar? Try to run the install on a local folder owned by your current user.

You could also try with sudo, that might solve a permission problem if that's the case.

Another reason why it cannot read could be because it has not downloaded correctly, or saved correctly. A little problem in your network could have caused that, and the cache clean would remove the files and force a refetch but that does not solve your problem. That means it would be more on the save part, maybe it didn't save because of permissions, maybe it didn't not save correctly because it was lacking disk space...

To run org.apache.http.legacy perfectely in Android 9.0 Pie create an xml file res/xml/network_security_config.xml

<?xml version="1.0" encoding="utf-8"?>
    <network-security-config>
      <base-config cleartextTrafficPermitted="true">
       <trust-anchors>
        <certificates src="system" />
       </trust-anchors>
      </base-config>
    </network-security-config>

And add 2 tags tag in your AndroidManifest.xml

android:networkSecurityConfig="@xml/network_security_config" android:name="org.apache.http.legacy"

<?xml version="1.0" encoding="utf-8"?>
 <manifest......>
  <application android:networkSecurityConfig="@xml/network_security_config">
   <activity..../> 
   ......
   ......
 <uses-library
        android:name="org.apache.http.legacy"
        android:required="false"/>
</application>

Also add useLibrary 'org.apache.http.legacy' in your app build gradle

android {
compileSdkVersion 28
defaultConfig {
    applicationId "your application id"
    minSdkVersion 15
    targetSdkVersion 28
    versionCode 1
    versionName "1.0"
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    useLibrary 'org.apache.http.legacy'
}

Would it not make sense to use msbuild directly? If you are doing this with every build, then you can add a msbuild task at the end? If you would just like to see if you can’t find another macro value that is not showed on the Visual Studio IDE, you could switch on the msbuild options to diagnostic and that will show you all of the variables that you could use, as well as their current value.

To switch this on in visual studio, go to Tools/Options then scroll down the tree view to the section called Projects and Solutions, expand that and click on Build and Run, at the right their is a drop down that specify the build output verbosity, setting that to diagnostic, will show you what other macro values you could use.

Because I don’t quite know to what level you would like to go, and how complex you want your build to be, this might give you some idea. I have recently been doing build scripts, that even execute SQL code as part of the build. If you would like some more help or even some sample build scripts, let me know, but if it is just a small process you want to run at the end of the build, the perhaps going the full msbuild script is a bit of over kill.

Hope it helps Rihan

Your file .idea/workspace.xml is not under git version control. You have either not added it yet (check git status/Untracked files) or ignored it (using .gitignore or .git/info/exclude files)

You can verify it using following git command, that lists all ignored files:

git ls-files --others -i --exclude-standard

Enyo's tutorial is excellent.

I found that the sample script in the tutorial worked well for a button embedded in the dropzone (i.e., the form element). If you wish to have the button outside the form element, I was able to accomplish it using a click event:

First, the HTML:

<form id="my-awesome-dropzone" action="/upload" class="dropzone">  
    <div class="dropzone-previews"></div>
    <div class="fallback"> <!-- this is the fallback if JS isn't working -->
        <input name="file" type="file" multiple />
    </div>

</form>
<button type="submit" id="submit-all" class="btn btn-primary btn-xs">Upload the file</button>

Then, the script tag....

Dropzone.options.myAwesomeDropzone = { // The camelized version of the ID of the form element

    // The configuration we've talked about above
    autoProcessQueue: false,
    uploadMultiple: true,
    parallelUploads: 25,
    maxFiles: 25,

    // The setting up of the dropzone
    init: function() {
        var myDropzone = this;

        // Here's the change from enyo's tutorial...

        $("#submit-all").click(function (e) {
            e.preventDefault();
            e.stopPropagation();
            myDropzone.processQueue();
        }); 
    }
}

list(map(chr, [66, 53, 0, 94]))

map(func, *iterables) --> map object Make an iterator that computes the function using arguments from each of the iterables. Stops when the shortest iterable is exhausted.

"Make an iterator"

means it will return an iterator.

"that computes the function using arguments from each of the iterables"

means that the next() function of the iterator will take one value of each iterables and pass each of them to one positional parameter of the function.

So you get an iterator from the map() funtion and jsut pass it to the list() builtin function or use list comprehensions.

This error usually happens when you have conflicting version (angular js). So the webpack could not start the application. You can simply fix it by removing the webpack and reinstall it.

npm uninstall webpack --save-dev
npm install webpack --save-dev

The restart your application and everything is fine.

I hope am able to help someone. Cheers

With the Return statement from the proc, I needed to assign the temp variable and pass it to another stored procedure. The value was getting assigned fine but when passing it as a parameter, it lost the value. I had to create a temp table and set the variable from the table (SQL 2008)

From this: 
declare @anID int
exec @anID = dbo.StoredProc_Fetch @ID, @anotherID, @finalID
exec dbo.ADifferentStoredProc @anID (no value here)

To this:
declare @t table(id int) 
declare @anID int
insert into @t exec dbo.StoredProc_Fetch @ID, @anotherID, @finalID
set @anID= (select Top 1 * from @t)

If the millis value is number of millis since Jan 1, 1970 GMT, as is standard for the JVM, then that is independent of time zone. If you want to format it with a specific time zone, you can simply convert it to a GregorianCalendar object and set the timezone. After that there are numerous ways to format it.

I think the tutorial passed by @emdhie will help a lot. How install maven

But, i followed and still getting mvn: command not found

I found this solution to know what was wrong in my configuration:

I opened the command line and called this command:

../apache-maven-3.5.3/bin/mvn --version

After that i got the correct JAVA_HOME and saw that my JAVA_HOME was wrong.

Hope this helps.

Other option:

SELECT CASE
    WHEN EXISTS (
        SELECT 1
        FROM [MyTable] AS [MyRecord])
    THEN CAST(1 AS BIT) ELSE CAST(0 AS BIT)
END

Speed

Lookups in lists are O(n), lookups in dictionaries are amortized O(1), with regard to the number of items in the data structure. If you don't need to associate values, use sets.

Memory

Both dictionaries and sets use hashing and they use much more memory than only for object storage. According to A.M. Kuchling in Beautiful Code, the implementation tries to keep the hash 2/3 full, so you might waste quite some memory.

If you do not add new entries on the fly (which you do, based on your updated question), it might be worthwhile to sort the list and use binary search. This is O(log n), and is likely to be slower for strings, impossible for objects which do not have a natural ordering.

You can fix it, that increasing the amount of inotify watchers.

If you are not interested in the technical details and only want to get Listen to work:

• If you are running Debian, RedHat, or another similar Linux distribution, run the following in a terminal:

  $ echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p

• If you are running ArchLinux, run the following command instead

  $ echo fs.inotify.max_user_watches=524288 | sudo tee /etc/sysctl.d/40-max-user-watches.conf && sudo sysctl --system

Then paste it in your terminal and press on enter to run it.

The Technical Details

Listen uses inotify by default on Linux to monitor directories for changes. It's not uncommon to encounter a system limit on the number of files you can monitor. For example, Ubuntu Lucid's (64bit) inotify limit is set to 8192.

You can get your current inotify file watch limit by executing:

$ cat /proc/sys/fs/inotify/max_user_watches

When this limit is not enough to monitor all files inside a directory, the limit must be increased for Listen to work properly.

You can set a new limit temporary with:

$ sudo sysctl fs.inotify.max_user_watches=524288
$ sudo sysctl -p

If you like to make your limit permanent, use:

$ echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf
$ sudo sysctl -p

You may also need to pay attention to the values of max_queued_events and max_user_instances if listen keeps on complaining.

Although <input> ignores the rows attribute, you can take advantage of the fact that <textarea> doesn't have to be inside <form> tags, but can still be a part of a form by referencing the form's id:

<form method="get" id="testformid">
    <input type="submit" />
</form> 
<textarea form ="testformid" name="taname" id="taid" cols="35" wrap="soft"></textarea>

Of course, <textarea> now appears below "submit" button, but maybe you'll find a way to reposition it.
