Thanks for all the fast Answers.

This is my solution:

Week.Sort(delegate(cTag c1, cTag c2) { return DateTime.Parse(c1.date).CompareTo(DateTime.Parse(c2.date)); });

Thanks

If the element is an <input type="text">, you should query the value attribute:

alert(element.value);

See an example in this jsFiddle.

Also, and seeing you're starting to learn HTML, you might consider using console.log() instead of alert() for debugging purposes. It doesn't interrupt the execution flow of the script, and you can have a general view of all logs in almost every browser with developer tools (except that one, obviously).

And of course, you could consider using a web development tool like Firebug, for instance, which is a powerful addon for Firefox that provides a lot of functionalities (debugging javascript code, DOM inspector, real-time DOM/CSS changes, request monitoring ...)

The WITH syntax appears to be valid in an inline view, e.g.

UPDATE (WITH comp AS ...
        SELECT SomeColumn, ComputedValue FROM t INNER JOIN comp ...)
   SET SomeColumn=ComputedValue;

But in the quick tests I did this always failed with ORA-01732: data manipulation operation not legal on this view, although it succeeded if I rewrote to eliminate the WITH clause. So the refactoring may interfere with Oracle's ability to guarantee key-preservation.

You should be able to use a MERGE, though. Using the simple example you've posted this doesn't even require a WITH clause:

MERGE INTO mytable t
USING (select *, 42 as ComputedValue from mytable where id = 1) comp
ON (t.id = comp.id)
WHEN MATCHED THEN UPDATE SET SomeColumn=ComputedValue;

But I understand you have a more complex subquery you want to factor out. I think that you will be able to make the subquery in the USING clause arbitrarily complex, incorporating multiple WITH clauses.

There are four ways to do this as I know

const array = [{id:1,name:'Jim'},{id:2,name:'Parker'}];
const toDelete = 1;

The first:

_.reject(array, {id:toDelete})

The second one is :

_.remove(array, {id:toDelete})

In this way the array will be mutated.

The third one is :

_.differenceBy(array,[{id:toDelete}],'id')
// If you can get remove item 
// _.differenceWith(array,[removeItem])

The last one is:

_.filter(array,({id})=>id!==toDelete)

Answer to make a record, so that I can find it later.

If you removed the make all line from your "fresh" target:

fresh :
    rm -f *.o $(EXEC)
    clear

You could simply run the command make fresh all, which will execute as make fresh; make all.

Some might consider this as a second instance of make, but it's certainly not a sub-instance of make (a make inside of a make), which is what your attempt seemed to result in.

Here is another one liner using lambdas (create column with constant value = 10)

df['newCol'] = df.apply(lambda x: 10, axis=1)

before

df
    A           B           C
1   1.764052    0.400157    0.978738
2   2.240893    1.867558    -0.977278
3   0.950088    -0.151357   -0.103219

after

df
        A           B           C           newCol
    1   1.764052    0.400157    0.978738    10
    2   2.240893    1.867558    -0.977278   10
    3   0.950088    -0.151357   -0.103219   10

function showstuff(boxid){
   document.getElementById(boxid).style.visibility="visible";
}

<button onclick="showstuff('id_to_show');" />

This will help you, I think.

Refer below Code Snip

In HTML Page

<input id="test" type="number" value="0"/>

In Java Script

document.getElementById("test").value=request.responseText;// in case of String 
document.getElementById("test").value=new Number(responseText);// in case of Number

final Properties properties = new Properties();
try (final InputStream stream =
           this.getClass().getResourceAsStream("foo.properties")) {
    properties.load(stream);
    /* or properties.loadFromXML(...) */
}

Add in AndroidManifest.xml for your activity:

android:windowSoftInputMode="adjustPan|adjustResize"

You can use this for color without alpha:

String hexColor = String.format("#%06X", (0xFFFFFF & intColor));

or this with alpha:

String hexColor = String.format("#%08X", (0xFFFFFFFF & intColor));

An additional way to do that (from the command line):

git config --global diff.tool tkdiff
git config --global merge.tool tkdiff
git config --global --add difftool.prompt false

The first two lines will set the difftool and mergetool to tkdiff- change that according to your preferences. The third line disables the annoying prompt so whenever you hit git difftool it will automatically launch the difftool.

You can go to the browser in Iphone/Ipad and type the URl where the IPA has been uploaded and can directly download it to your Iphone or Ipad and install and run it.... simple and sweet ;)

If anyone has problems with using a custom dateformat for java.sql.Date, this is the simplest solution:

ObjectMapper mapper = new ObjectMapper();
SimpleModule module = new SimpleModule();
module.addSerializer(java.sql.Date.class, new DateSerializer());
mapper.registerModule(module);

(This SO-answer saved me a lot of trouble: https://stackoverflow.com/a/35212795/3149048 )

Jackson uses the SqlDateSerializer by default for java.sql.Date, but currently, this serializer doesn't take the dateformat into account, see this issue: https://github.com/FasterXML/jackson-databind/issues/1407 . The workaround is to register a different serializer for java.sql.Date as shown in the code example.

To Remove RED EXCLAMATION mark on project,
I have deleted all JAR files using BUILD Path--> LIBRARY --> ADD EXTERNAL JARs and remove all or selected JAR.
Reinstall again.
This action resolve my issue with Red exclamation mark.

You can do it with HttpWebRequest:

var httpWebRequest = (HttpWebRequest)WebRequest.Create("http://yourUrl");
httpWebRequest.ContentType = "application/json";
httpWebRequest.Method = "POST";
ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12 | SecurityProtocolType.Tls11 | SecurityProtocolType.Tls;

using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
{
    string json = new JavaScriptSerializer().Serialize(new
            {
                Username = "myusername",
                Password = "pass"
            });
    streamWriter.Write(json);
    streamWriter.Flush();
    streamWriter.Close();
}

var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
{
    var result = streamReader.ReadToEnd();
}

Don't forget, union all is a way to add records to a record set without sorting or merging (as opposed to union).

So for example:

select * from (
    select col1, col2
    from table a
    <....>
    order by col3
    limit by 200
) a
union all
select * from (
    select cola, colb
    from table b
    <....>
    order by colb
    limit by 300
) b

It keeps the individual queries clearer and allows you to sort by different parameters in each query. However by using the selected answer's way it might become clearer depending on complexity and how related the data is because you are conceptualizing the sort. It also allows you to return the artificial column to the querying program so it has a context it can sort by or organize.

But this way has the advantage of being fast, not introducing extra variables, and making it easy to separate out each query including the sort. The ability to add a limit is simply an extra bonus.

And of course feel free to turn the union all into a union and add a sort for the whole query. Or add an artificial id, in which case this way makes it easy to sort by different parameters in each query, but it otherwise is the same as the accepted answer.

First, you don't need the .class files if they are compiled from your .java classes.

To import your files, you need to create an empty Java project. They you either import them one by one (New -> File -> Advanced -> Link file) or directly copy them into their corresponding folder/package and refresh the project.

I usually use this workaround:

try:
    from .mymodule import myclass
except Exception: #ImportError
    from mymodule import myclass

Which means your IDE should pick up the right code location and the python interpreter will manage to run your code.

You could use the ready to use Url Rewrite Filter with a rule like this one:

<rule>
  <from>^/Check_License/Dir_My_App/Dir_ABC/My_Obj_([0-9]+)$</from>
  <to>/Check_License?Contact_Id=My_Obj_$1</to>
</rule>

Check the Examples for more... examples.

One thing that hasn't been explicitly mentioned - the scope feature gives you an option to have the same name for an enum and class method. For instance:

class Test
{
public:
   // these call ProcessCommand() internally
   void TakeSnapshot();
   void RestoreSnapshot();
private:
   enum class Command // wouldn't be possible without 'class'
   {
        TakeSnapshot,
        RestoreSnapshot
   };
   void ProcessCommand(Command cmd); // signal the other thread or whatever
};

import datetime
a = datetime.datetime.today().year

or even (as Lennart suggested)

a = datetime.datetime.now().year

or even

a = datetime.date.today().year

The general approach to write to any stream (not only MemoryStream) is to use BinaryWriter:

static void Write(Stream s, Byte[] bytes)
{
    using (var writer = new BinaryWriter(s))
    {
        writer.Write(bytes);
    }
}

I solved my problem. it's just the version of python which the interpreter reads off the first line. removing to version numbers did it for me, i.e.

#!/usr/bin/python2.7 --> #!/usr/bin/python

Please use this on SQL Server 2005:

sp_rename old_table_name , new_table_name

it will give you:

Caution: Changing any part of an object name could break scripts and stored procedures.

but your table name will be changed.

The widely accepted answer by Adam Hopkinson is not a fully automated method of creating a page! It requires a user to manually create a page in the back-end of WordPress (in the wp-admin dash). The problem with that is, a good plugin should have a fully automated setup. It should not require clients to manually create pages.

Also, some of the other widely accepted answers here involve creating a static page outside of WordPress, which then include only some of the WordPress functionality to achieve the themed header and footer. While that method may work in some cases, this can make integrating these pages with WordPress very difficult without having all its functionality included.

I think the best, fully automated, approach would be to create a page using wp_insert_post and have it reside in the database. An example and a great discussion about that, and how to prevent accidental deletion of the page by a user, can be found here: wordpress-automatically-creating-page

Frankly, I'm surprised this approach hasn't already been mentioned as an answer to this popular question (it has been posted for 7 years).

It means that you wrote to some variables on the stack in an illegal way, most likely as the result of a Buffer overflow.

Toggle the text Show and Hide and move your backgroundPosition Y axis

LIVE DEMO

$(function(){ // DOM READY shorthand

    $(".slidingDiv").hide();

    $('.show_hide').click(function( e ){
        // e.preventDefault(); // If you use anchors
        var SH = this.SH^=1; // "Simple toggler"
        $(this).text(SH?'Hide':'Show')
               .css({backgroundPosition:'0 '+ (SH?-18:0) +'px'})
               .next(".slidingDiv").slideToggle();
    });

});

CSS:

.show_hide{
  background:url(plusminus.png) no-repeat;
  padding-left:20px;  
}

If you're looking for a cross-platform GUI, then I'd highly recommend going with JRuby and Swing.

Also, take a look at the monkeybars library, which is a Ruby library for building MVC applications using JRuby and Swing, where you can also use the excellent Netbeans IDE to visually build your GUI.

Apple mail has also been known to make an encoding error on text and csv attachments outbound. In essence it replaces line terminators with soft line breaks on each line, which look like =0D in the encoding. If the attachment is emailed to Outlook, Outlook sees the soft line breaks, removes the = then appends real line breaks i.e. 0D0A so you get 0D0D0A (cr cr lf) at the end of each line. The encoding should be =0D= if it is a mac format file (or any other flavour of unix) or =0D0A= if it is a windows format file.

If you are emailing out from apple mail (in at least mavericks or yosemite), making the attachment not a text or csv file is an acceptable workaround e.g. compress it.

The bug also exists if you are running a windows VM under parallels and email a txt file from there using apple mail. It is the email encoding. Form previous comments here, it looks like netscape had the same issue.

you can save the xlsx file as a tab-delimited text file and do

BULK INSERT TableName
        FROM 'C:\SomeDirectory\my table.txt'
            WITH
    (
                FIELDTERMINATOR = '\t',
                ROWTERMINATOR = '\n'
    )
GO

As long as you're increasing the size of your varchar you're OK. As per the Alter Table reference:

Reducing the precision or scale of a column may cause data truncation.

I can give an example commonly seen in project.

Here, option --no-ff (i.e. true merge) creates a new commit with multiple parents, and provides a better history tracking. Otherwise, --ff (i.e. fast-forward merge) is by default.

$ git checkout master
$ git checkout -b newFeature
$ ...
$ git commit -m 'work from day 1'
$ ...
$ git commit -m 'work from day 2'
$ ...
$ git commit -m 'finish the feature'
$ git checkout master
$ git merge --no-ff newFeature -m 'add new feature'
$ git log
// something like below
commit 'add new feature'         // => commit created at merge with proper message
commit 'finish the feature'
commit 'work from day 2'
commit 'work from day 1'
$ gitk                           // => see details with graph

$ git checkout -b anotherFeature        // => create a new branch (*)
$ ...
$ git commit -m 'work from day 3'
$ ...
$ git commit -m 'work from day 4'
$ ...
$ git commit -m 'finish another feature'
$ git checkout master
$ git merge anotherFeature       // --ff is by default, message will be ignored
$ git log
// something like below
commit 'work from day 4'
commit 'work from day 3'
commit 'add new feature'
commit 'finish the feature'
commit ...
$ gitk                           // => see details with graph

(*) Note that here if the newFeature branch is re-used, instead of creating a new branch, git will have to do a --no-ff merge anyway. This means fast forward merge is not always eligible.

I've found timezone.make_aware(datetime.datetime.now()) is helpful in django (I'm on 1.9.1). Unfortunately you can't simply make a datetime object offset-aware, then timetz() it. You have to make a datetime and make comparisons based on that.

I do not like transformations to have any more info than needed. So instead of restating the keys, I simply state the condition and intention. It is much easier to see the intention when done like this, at least IMO. Also, I try and put all the xdt attributes first to indicate to the reader, these are transformations and not new things being defined.

<appSettings>
  <add xdt:Locator="Condition(@key='developmentModeUserId')" xdt:Transform="Remove" />
  <add xdt:Locator="Condition(@key='developmentMode')" xdt:Transform="SetAttributes"
       value="false"/>
</appSettings>

In the above it is much easier to see that the first one is removing the element. The 2nd one is setting attributes. It will set/replace any attributes you define here. In this case it will simply set value to false.

Old Question... But I want to add something not already stated by anyone here... (Note: This is my own observation, so don't ask for any reference)

Datetime2 is faster when used in filter criteria.

TLDR:

In SQL 2016 I had a table with hundred thousand rows and a datetime column ENTRY_TIME because it was required to store the exact time up to seconds. While executing a complex query with many joins and a sub query, when I used where clause as:

WHERE ENTRY_TIME >= '2017-01-01 00:00:00' AND ENTRY_TIME < '2018-01-01 00:00:00'

The query was fine initially when there were hundreds of rows, but when number of rows increased, the query started to give this error:

Execution Timeout Expired. The timeout period elapsed prior
to completion of the operation or the server is not responding.

I removed the where clause, and unexpectedly, the query was run in 1 sec, although now ALL rows for all dates were fetched. I run the inner query with where clause, and it took 85 seconds, and without where clause it took 0.01 secs.

I came across many threads here for this issue as datetime filtering performance

I optimized query a bit. But the real speed I got was by changing the datetime column to datetime2.

Now the same query that timed out previously takes less than a second.

cheers

I'm running Ubuntu 20 and I had a similar problem

Installed ffmpeg

pip install ffmpeg

then

sudo apt install ffmpeg

Just restating what Tomasz said.

There are many examples of FOO__in=... style filters in the many-to-many and many-to-one tests. Here is syntax for your specific problem:

users_in_1zone = User.objects.filter(zones__id=<id1>)
# same thing but using in
users_in_1zone = User.objects.filter(zones__in=[<id1>])

# filtering on a few zones, by id
users_in_zones = User.objects.filter(zones__in=[<id1>, <id2>, <id3>])
# and by zone object (object gets converted to pk under the covers)
users_in_zones = User.objects.filter(zones__in=[zone1, zone2, zone3])

The double underscore (__) syntax is used all over the place when working with querysets.

I ran into similar issues whose cause and solution turned out both to be rather simple:

Main Cause: Did not import the proper cert using keytool

NOTE: Only import root CA (or your own self-signed) certificates

NOTE: don't import an intermediate, non certificate chain root cert

Solution Example for imap.gmail.com

1. Determine the root CA cert:

   openssl s_client -showcerts -connect imap.gmail.com:993
   

   in this case we find the root CA is Equifax Secure Certificate Authority

2. Download root CA cert.
3. Verify downloaded cert has proper SHA-1 and/or MD5 fingerprints by comparing with info found here

4. Import cert for javax.net.ssl.trustStore:

   keytool -import -alias gmail_imap -file Equifax_Secure_Certificate_Authority.pem
   

5. Run your java code

The best way to help memory to be freed is to nullify large objects:

Sub Whatever()
    Dim someLargeObject as SomeObject

    'expensive computation

    Set someLargeObject = Nothing
End Sub

Also note that global variables remain allocated from one call to another, so if you don't need persistence you should either not use global variables or nullify them when you don't need them any longer.

However this won't help if:

• you need the object after the procedure (obviously)
• your object does not fit in memory

Another possibility is to switch to a 64 bit version of Excel which should be able to use more RAM before crashing (32 bits versions are typically limited at around 1.3GB).

Tickcount is good, however i suggest running it 100 or 1000 times, and calculating an average. Not only makes it more measurable - in case of really fast/short functions, but helps dealing with some one-off effects caused by the overhead.

Since Java 8, there are some standard options to do this in JDK:

Collection<E> in = ...
Object[] mapped = in.stream().map(e -> doMap(e)).toArray();
// or
List<E> mapped = in.stream().map(e -> doMap(e)).collect(Collectors.toList());

See java.util.Collection.stream() and java.util.stream.Collectors.toList().

Remove YouTube Branding

To date: Seeing a lot of searches and suggestions to disable YouTube logo and branding from an embedded video; I recommend you consider the following:

1. I guess YouTube don't want you to do this otherwise they would allow that at their front end.
2. Some brands spending huge efforts to provide the media not for a 5 min. removal.
3. It's good to have the logo and respects brands rights.
4. You still have the video and the luxury of embedding it in your site/blog.
5. Spare some of your time; that is not possible.

6. Yet! You have the option of having Modest-Branding using this parameters:

   https://www.youtube.com/embed/'+videourl+'?modestbranding=1

And some other parameters for customization:

&showinfo=0 //Turn off Title & Ratings

&showsearch=0 //Turn off Search

&rel=1 //Turn on Related Videos

&iv_load_policy=3 //Turn off Annotations

&cc_load_policy=1 //Force Closed Captions

&autoplay=1 //Turn on AutoPlay (not recommended)

&loop=1 //Loop Playback

&fs=0 //Remove Full Screen Option (not sure why you’d want to)

And here is the general customization window:

^{Disclaimer: I don't work for YouTube; simply I respect the copyrights.}

If you have access to you httpd.conf file (in ubuntu it is in the /etc/apache2 directory), you should add the same lines that you would to the .htaccess file in the specific directory. That is (for example):

ServerName YOURSERVERNAMEHERE
<Directory /var/www/>
AllowOverride None
order deny,allow
Options -Indexes FollowSymLinks
</Directory>

Do this for every directory that you want to control the information, and you will have one file in one spot to manage all access. It the example above, I did it for the root directory, /var/www.

This option may not be available with outsourced hosting, especially shared hosting. But it is a better option than adding many .htaccess files.

All DDL statements in Oracle PL/SQL should use Execute Immediate before the statement. Hence you should use:

execute immediate 'truncate table schema.tablename';

Use a real dropdown menu instead: a list (ul, li) and links. Never misuse form elements as links.

Readers with screen readers usually scan through a automagically generated list of links – the’ll miss these important information. Many keyboard navigation systems (e.g. JAWS, Opera) offer different keyboard shortcuts for links and form elements.

If you still cannot drop the idea of a select don’t use the onchange handler at least. This is a real pain for keyboard users, it makes your third item nearly inaccessible.

Here is my simple but efficient algorithm (in C++) for calculating running median from a stream of integers:

#include<algorithm>
#include<fstream>
#include<vector>
#include<list>

using namespace std;

void runningMedian(std::ifstream& ifs, std::ofstream& ofs, const unsigned bufSize) {
    if (bufSize < 1)
        throw exception("Wrong buffer size.");
    bool evenSize = bufSize % 2 == 0 ? true : false;
    list<int> q;
    vector<int> nums;
    int n;
    unsigned count = 0;
    while (ifs.good()) {
        ifs >> n;
        q.push_back(n);
        auto ub = std::upper_bound(nums.begin(), nums.end(), n);
        nums.insert(ub, n);
        count++;
        if (nums.size() >= bufSize) {
            auto it = std::find(nums.begin(), nums.end(), q.front());
            nums.erase(it);
            q.pop_front();
            if (evenSize)
                ofs << count << ": " << (static_cast<double>(nums[nums.size() / 2 - 1] +
                static_cast<double>(nums[nums.size() / 2]))) / 2.0 << '\n';
            else
                ofs << count << ": " << static_cast<double>(nums[nums.size() / 2]);
        }
    }
}

The bufferSize specifies the size of the numbers sequence, on which the running median must be calculated. When reading numbers from the input stream ifs the vector of the size bufferSize is maintained in sorted order. The median is calculated by taking the middle of the sorted vector, if bufferSize is odd, or the sum of the two middle elements divided by 2, when bufferSize is even. Additinally, I maintain a list of last bufferSize elements read from input. When a new element is added, I put it in the right place in sorted vector and remove from the vector the element added bufferSize steps before (the value of the element retained in the front of the list). In the same time I remove the old element from the list: every new element is placed on the back of the list, every old element is removed from the front. After reaching the bufferSize, both the list and the vector stop to grow, and every insertion of a new element is compensated be deletion of an old element, placed in the list bufferSize steps before. Note, I do not care, whether I remove from the vector exactly the element, placed bufferSize steps before, or just an element that has the same value. For the value of median it does not matter. All calculated median values are output in the output stream.

In order to keep track of dependency issues, I like to use the conda installer, which simply boils down to:

conda install openpyxl

I had the same problem, and it came from a wrong client_id / Facebook App ID.

Did you switch your Facebook app to "public" or "online ? When you do so, Facebook creates a new app with a new App ID.

You can compare the "client_id" parameter value in the url with the one in your Facebook dashboard.

function check (list){
    var foundRepeatingValue = false;
    var newList = [];
    for(i=0;i<list.length;i++){
        var thisValue = list[i];
        if(i>0){
            if(newList.indexOf(thisValue)>-1){
                foundRepeatingValue = true;
                console.log("getting repeated");
                return true;
            }
       } newList.push(thisValue);
    } return false;
}

var list1 = ["dse","dfg","dse"];
check(list1);

Output:

getting repeated
true

You will not have access to your real sd card in emulator. You will have to follow the steps in this tutorial to direct your emulator to a directory on your development environment acting as your SD card.

Sometimes it doesnt fire when the script has some syntax error, make sure the script and javascript syntax is correct.

To cater for the schema as well, use this format in SQL 2014

if exists(select 1 from sys.views V inner join sys.[schemas] S on  v.schema_id = s.schema_id where s.name='dbo' and v.name = 'someviewname' and v.type = 'v')
  drop view [dbo].[someviewname];
go

And just throwing it out there, to do stored procedures, because I needed that too:

if exists(select 1
          from sys.procedures p
          inner join sys.[schemas] S on p.schema_id = s.schema_id
          where
              s.name='dbo' and p.name = 'someprocname'
          and p.type in ('p', 'pc')
  drop procedure [dbo].[someprocname];
go

Try this:

import os
import sys

This is the code that I've found to run the fastest so far. I ran it on 109015 byte arrays of length 32, in 23ms. I was running it on a VM so it'll probably run faster on bare metal.

public static final char[] HEX_DIGITS =         {'0', '1', '2', '3', '4', '5', '6', '7', '8', '9', 'A', 'B', 'C', 'D', 'E', 'F'};

public static char[] encodeHex( final byte[] data ){
    final int l = data.length;
    final char[] out = new char[l<<1];
    for( int i=0,j=0; i<l; i++ ){
        out[j++] = HEX_DIGITS[(0xF0 & data[i]) >>> 4];
        out[j++] = HEX_DIGITS[0x0F & data[i]];
    }
    return out;
}

Then you can just do

String s = new String( encodeHex(myByteArray) );

0.1 second Google search:

BOOL DirectoryExists(const char* dirName) {
  DWORD attribs = ::GetFileAttributesA(dirName);
  if (attribs == INVALID_FILE_ATTRIBUTES) {
    return false;
  }
  return (attribs & FILE_ATTRIBUTE_DIRECTORY);
}

You can easily redirect different parts of your shell script to a file (or several files) using sub-shells:

{
  command1
  command2
  command3
  command4
} > file1
{
  command5
  command6
  command7
  command8
} > file2

This may be of help to a few who are struggling like I was:

var data = myform.getRange("A:AA").getValues().pop();
var myvariable1 = data[4];
var myvariable2 = data[7];

You're returning the address of a local variable allocated on the stack. When your function returns, the storage for all local variables (such as wc) is deallocated and is subject to being immediately overwritten by something else.

To fix this, you can pass the size of the buffer to GetWC, but then you've got pretty much the same interface as mbstowcs itself. Or, you could allocate a new buffer inside GetWC and return a pointer to that, leaving it up to the caller to deallocate the buffer.

This only worked for me...

txtSerialLogging->Text = "";

txtSerialLogging->AppendText(s);

I tried all the cases above, but the problem is in my case text s can decrease, increase and can also remain static for a long time. static means , static length(lines) but content is different.

So, I was facing one line jumping situation at the end when the length(lines) remains same for some times...

The value attribute on submit-type <input> elements controls the text displayed.

<input type="submit" class="like" value="Like" />

You need to set a layout manager for the JFrame to use - This deals with how components are positioned. A useful one is the BorderLayout manager.

Simply adding the following line of code should fix your problems:

mainFrame.setLayout(new BorderLayout());

(Do this before adding components to the JFrame)

JQuery has a way to pass parameters from HTML to javascript:

Put this in the myhtml.html file:

<!-- Import javascript -->
<script src="//code.jquery.com/jquery-1.11.2.min.js"></script>
<!-- Invoke a different javascript file called subscript.js -->
<script id="myscript" src="subscript.js" video_filename="foobar.mp4">/script>

In the same directory make a subscript.js file and put this in there:

//Use jquery to look up the tag with the id of 'myscript' above.  Get 
//the attribute called video_filename, stuff it into variable filename.
var filename = $('#myscript').attr("video_filename");

//print filename out to screen.
document.write(filename);

Analyze Result:

Loading the myhtml.html page has 'foobar.mp4' print to screen. The variable called video_filename was passed from html to javascript. Javascript printed it to screen, and it appeared as embedded into the html in the parent.

jsfiddle proof that the above works:

If you have the OAuth PHP library installed, you don't have to worry about forming the request yourself.

$oauth = new OAuth($consumer_key, $consumer_secret, OAUTH_SIG_METHOD_HMACSHA1, OAUTH_AUTH_TYPE_URI);
$oauth->setToken($access_token, $access_secret);

$oauth->fetch("https://api.twitter.com/1.1/statuses/user_timeline.json");
$twitter_data = json_decode($oauth->getLastResponse());

print_r($twitter_data);

For more information, check out The docs or their example. You can use pecl install oauth to get the library.

Use whoami /priv command to list all the user privileges.

Try the following:

ToString("X4")

See The X format specifier on MSDN.

First method

This method seems to work when the content doesn't include ?.

Install xsel or similar and assign a global shortcut key for this command in your WM or DE:

xsel -o | sed -r 's/^ ?[[:digit:]]+($| +)//g' | perl -pe 's/\n/?/g' | sed -r 's/??/\n\n/g; s/ ?? {1,}/ /g; s/?/\n/g' | xsel -b

Put this in your ~/.Xresources:

*selectToClipboard: false

Issue this in your xterm once to activate the above option:

xrdb -load ~/.Xresources

Now select the line(s) including the line numbers by pressing Shift while dragging the mouse. After the selection click your key combo; the line(s) are coppied and ready to be pasted anywhere you like.

Second method

Doesn't have the shortcoming of the first method.

Install xdotool and xsel or similar.

Put these two lines

Ctrl <Btn3Down>: select-start(PRIMARY, CLIPBOARD)
Ctrl <Btn3Up>: select-end(CLIPBOARD, PRIMARY)

in your ~/.Xresources like so:

*VT100*translations: #override \n\
    Alt <Key> 0xf6: exec-formatted("xdg-open '%t'", PRIMARY, CUT_BUFFER0) \n\                           
    Ctrl <Key>0x2bb: copy-selection(CLIPBOARD) \n\                              
    Alt <Key>0x2bb: insert-selection(CLIPBOARD) \n\                             
    Ctrl <Key> +:       larger-vt-font() \n\                                    
    Ctrl <Key> -:       smaller-vt-font() \n\
    Ctrl <Btn3Down>: select-start(PRIMARY, CLIPBOARD) \n\
    Ctrl <Btn3Up>: select-end(CLIPBOARD, PRIMARY) 

Issue this in your xterm once to activate the above option:

xrdb -load ~/.Xresources

Create this scrip in your path:

#!/bin/bash                                                                  

filepid=$(xdotool getwindowpid $(xdotool getactivewindow))                   
file=$(ps -p "$filepid" o cmd | grep -o --color=never "/.*")                   

firstline=$(xsel -b)                                                         
lastline=$(xsel)                                                             

sed -n ""$firstline","$lastline"p" "$file" | xsel -b

Assign a global shortcut key to call this script in your WM or DE.

Now when you want to copy a line (paragraph), select only the line number of that line (paragraph) by right mouse button while pressing Shift+Ctrl. After the selection click your custom global key combo you've created before. The line (paragraph) is coppied and ready to be pasted anywhere you like.

If you want to copy multiple lines, do the above for the first line and then for the last line of the range, instead of Shift+Ctrl+Btn3 (right mouse button), just select the number by left mouse button while pressing only Shift. After this, again call the script by your custom global shortcut. The range of lines are coppied and ready to pasted anywhere you like.

I asked a similar question. Based on @sawa's answer, the most succinct way to represent an integer in a string in binary format is to use the string formatter:

"%b" % 245
=> "11110101"

You can also choose how long the string representation to be, which might be useful if you want to compare fixed-width binary numbers:

1.upto(10).each { |n| puts "%04b" % n }
0001
0010
0011
0100
0101
0110
0111
1000
1001
1010

<?php
// sample array
$fruits3 = [
    "iron",
    1,
    "ascorbic",
    "potassium",
    "ascorbic",
    2,
    "2",
    "1",
];

// Let's say we are looking for the item "ascorbic", in the above array

//a PHP function matching indexOf() from JS
echo(array_search("ascorbic", $fruits3, true)); //returns "2"

// a PHP function matching lastIndexOf() from JS world
function lastIndexOf($needle, $arr)
{
    return array_search($needle, array_reverse($arr, true), true);
}

echo(lastIndexOf("ascorbic", $fruits3)); //returns "4"

// so these (above) are the two ways to run a function similar to indexOf and lastIndexOf()

std::string str = "STriNg oF mIxID CasE lETteRS"

C++ 11

• Using for_each

  std::for_each(str.begin(), str.end(), [](char & c){ c = ::toupper(c); });

• Using transform

  std::transform(str.begin(), str.end(), str.begin(), ::toupper);

C++ (Winodws Only)

_strupr_s(str, str.length());

C++ (Using Boost Library)

boost::to_upper_copy(str)

There is a method of UIScrollViewDelegate which can be used to detect (or better to say 'predict') when scrolling has really finished:

func scrollViewWillEndDragging(_ scrollView: UIScrollView, withVelocity velocity: CGPoint, targetContentOffset: UnsafeMutablePointer<CGPoint>)

of UIScrollViewDelegate which can be used to detect (or better to say 'predict') when scrolling has really finished.

In my case I used it with horizontal scrolling as following (in Swift 3):

func scrollViewWillEndDragging(_ scrollView: UIScrollView, withVelocity velocity: CGPoint, targetContentOffset: UnsafeMutablePointer<CGPoint>) {
    perform(#selector(self.actionOnFinishedScrolling), with: nil, afterDelay: Double(velocity.x))
}
func actionOnFinishedScrolling() {
    print("scrolling is finished")
    // do what you need
}

You can also use the code below, if you do not want to get IndexError when the list is empty.

next(reversed(some_list), None)

If you really want to split every word (bash meaning) into a different array index completely changing the array in every while loop iteration, @ruakh's answer is the correct approach. But you can use the read property to split every read word into different variables column1, column2, column3 like in this code snippet

while IFS=$'\t' read -r column1 column2 column3 ; do
  printf "%b\n" "column1<${column1}>"
  printf "%b\n" "column2<${column2}>"
  printf "%b\n" "column3<${column3}>"
done < "myfile"

to reach a similar result avoiding array index access and improving your code readability by using meaningful variable names (of course using columnN is not a good idea to do so).

You can add references to your model through command line in the following manner:

rails g migration add_column_to_tester user_id:integer

This will generate a migration file like :

class AddColumnToTesters < ActiveRecord::Migration
  def change
    add_column :testers, :user_id, :integer
  end
end

This works fine every time i use it..

\r can do the work here for you.

I found that some applications like Numbers in Mac ignore the double quote if there is space before it.

a, "b,c" doesn't work while a,"b,c" works.

You can set proxies using environment variables.

import os
os.environ['http_proxy'] = '127.0.0.1'
os.environ['https_proxy'] = '127.0.0.1'

urllib2 will add proxy handlers automatically this way. You need to set proxies for different protocols separately otherwise they will fail (in terms of not going through proxy), see below.

For example:

proxy = urllib2.ProxyHandler({'http': '127.0.0.1'})
opener = urllib2.build_opener(proxy)
urllib2.install_opener(opener)
urllib2.urlopen('http://www.google.com')
# next line will fail (will not go through the proxy) (https)
urllib2.urlopen('https://www.google.com')

Instead

proxy = urllib2.ProxyHandler({
    'http': '127.0.0.1',
    'https': '127.0.0.1'
})
opener = urllib2.build_opener(proxy)
urllib2.install_opener(opener)
# this way both http and https requests go through the proxy
urllib2.urlopen('http://www.google.com')
urllib2.urlopen('https://www.google.com')

Of course the "You shall not instantiate an item of this class" statement has been violated, but if this is the logic behind that, then we should all throw AssertionErrors everywhere, and that is obviously not what happens.

The code isn't saying the user shouldn't call the zero-args constructor. The assertion is there to say that as far as the programmer is aware, he/she has made it impossible to call the zero-args constructor (in this case by making it private and not calling it from within Example's code). And so if a call occurs, that assertion has been violated, and so AssertionError is appropriate.

There is nothing built into Java at the moment of writing this. I would suggest writing your own implementation. My preference is for a simple fluent builder interface instead of creating a map and passing it to function -- you end up with a nice contiguous chunk of code, for example:

String result = new TemplatedStringBuilder("My name is {{name}} and I from {{town}}")
   .replace("name", "John Doe")
   .replace("town", "Sydney")
   .finish();

Here is a simple implementation:

class TemplatedStringBuilder {

    private final static String TEMPLATE_START_TOKEN = "{{";
    private final static String TEMPLATE_CLOSE_TOKEN = "}}";

    private final String template;
    private final Map<String, String> parameters = new HashMap<>();

    public TemplatedStringBuilder(String template) {
        if (template == null) throw new NullPointerException();
        this.template = template;
    }

    public TemplatedStringBuilder replace(String key, String value){
        parameters.put(key, value);
        return this;
    }

    public String finish(){

        StringBuilder result = new StringBuilder();

        int startIndex = 0;

        while (startIndex < template.length()){

            int openIndex  = template.indexOf(TEMPLATE_START_TOKEN, startIndex);

            if (openIndex < 0){
                result.append(template.substring(startIndex));
                break;
            }

            int closeIndex = template.indexOf(TEMPLATE_CLOSE_TOKEN, openIndex);

            if(closeIndex < 0){
                result.append(template.substring(startIndex));
                break;
            }

            String key = template.substring(openIndex + TEMPLATE_START_TOKEN.length(), closeIndex);

            if (!parameters.containsKey(key)) throw new RuntimeException("missing value for key: " + key);

            result.append(template.substring(startIndex, openIndex));
            result.append(parameters.get(key));

            startIndex = closeIndex + TEMPLATE_CLOSE_TOKEN.length();
        }

        return result.toString();
    }
}

Keep in mind if you are wanting to test this component you will want to inject the window. Use the @Inject() function to inject the window object by naming it using a string token like detailed in this duplicate

import threading 

# global variable x 
x = 0

def increment(): 
    """ 
    function to increment global variable x 
    """
    global x 
    x += 1

def thread_task(): 
    """ 
    task for thread 
    calls increment function 100000 times. 
    """
    for _ in range(100000): 
        increment() 

def main_task(): 
    global x 
    # setting global variable x as 0 
    x = 0

    # creating threads 
    t1 = threading.Thread(target=thread_task) 
    t2 = threading.Thread(target=thread_task) 

    # start threads 
    t1.start() 
    t2.start() 

    # wait until threads finish their job 
    t1.join() 
    t2.join() 

if __name__ == "__main__": 
    for i in range(10): 
        main_task() 
        print("Iteration {0}: x = {1}".format(i,x))

You are mixing the 1.5.6 version of the jcl bridge with the 1.6.0 version of the slf4j-api; this won't work because of a few changes in 1.6.0. Use the same versions for both, i.e. 1.6.1 (the latest). I use the jcl-over-slf4j bridge all the time and it works fine.

You can follow this approach:

void addOrUpdate(Dictionary<int, int> dic, int key, int newValue)
{
    int val;
    if (dic.TryGetValue(key, out val))
    {
        // yay, value exists!
        dic[key] = val + newValue;
    }
    else
    {
        // darn, lets add the value
        dic.Add(key, newValue);
    }
}

The edge you get here is that you check and get the value of corresponding key in just 1 access to the dictionary. If you use ContainsKey to check the existance and update the value using dic[key] = val + newValue; then you are accessing the dictionary twice.

Here's a method you can use to rotate an image in C#:

/// <summary>
/// method to rotate an image either clockwise or counter-clockwise
/// </summary>
/// <param name="img">the image to be rotated</param>
/// <param name="rotationAngle">the angle (in degrees).
/// NOTE: 
/// Positive values will rotate clockwise
/// negative values will rotate counter-clockwise
/// </param>
/// <returns></returns>
public static Image RotateImage(Image img, float rotationAngle)
{
    //create an empty Bitmap image
    Bitmap bmp = new Bitmap(img.Width, img.Height);

    //turn the Bitmap into a Graphics object
    Graphics gfx = Graphics.FromImage(bmp);

    //now we set the rotation point to the center of our image
    gfx.TranslateTransform((float)bmp.Width / 2, (float)bmp.Height / 2);

    //now rotate the image
    gfx.RotateTransform(rotationAngle);

    gfx.TranslateTransform(-(float)bmp.Width / 2, -(float)bmp.Height / 2);

    //set the InterpolationMode to HighQualityBicubic so to ensure a high
    //quality image once it is transformed to the specified size
    gfx.InterpolationMode = InterpolationMode.HighQualityBicubic;

    //now draw our new image onto the graphics object
    gfx.DrawImage(img, new Point(0, 0));

    //dispose of our Graphics object
    gfx.Dispose();

    //return the image
    return bmp;
}

The directory must be empty and your program must have permissions to delete it

but the function called rmdir will do it

rmdir("C:/Documents and Settings/user/Desktop/itsme") 

Just echo the javascript out inside the if function

 <form name="testForm" id="testForm"  method="POST"  >
     <input type="submit" name="btn" value="submit" autofocus  onclick="return true;"/>
 </form>
 <?php
    if(isset($_POST['btn'])){
        echo "
            <script type=\"text/javascript\">
            var e = document.getElementById('testForm'); e.action='test.php'; e.submit();
            </script>
        ";
     }
  ?>

Also set the field to disabled when you disable the datePicker e.g

$("input").prop('disabled', true);

To stop the image being clickable you could unbind the click event on that

$('img#<id or class ref>').unbind('click');

With Firefox, Safari (and other Gecko based browsers) you can easily use textarea.selectionStart, but for IE that doesn't work, so you will have to do something like this:

function getCaret(node) {
  if (node.selectionStart) {
    return node.selectionStart;
  } else if (!document.selection) {
    return 0;
  }

  var c = "\001",
      sel = document.selection.createRange(),
      dul = sel.duplicate(),
      len = 0;

  dul.moveToElementText(node);
  sel.text = c;
  len = dul.text.indexOf(c);
  sel.moveStart('character',-1);
  sel.text = "";
  return len;
}

(complete code here)

I also recommend you to check the jQuery FieldSelection Plugin, it allows you to do that and much more...

Edit: I actually re-implemented the above code:

function getCaret(el) { 
  if (el.selectionStart) { 
    return el.selectionStart; 
  } else if (document.selection) { 
    el.focus(); 

    var r = document.selection.createRange(); 
    if (r == null) { 
      return 0; 
    } 

    var re = el.createTextRange(), 
        rc = re.duplicate(); 
    re.moveToBookmark(r.getBookmark()); 
    rc.setEndPoint('EndToStart', re); 

    return rc.text.length; 
  }  
  return 0; 
}

Check an example here.

Introduction

Since it is not really clear from your question what exactly you are having trouble with, I wrote up this quick walkthrough about how to implement this feature; if you still have questions feel free to ask.

I have a working example of everything I am talking about here in this GitHub Repository.
If you want to know more about the example project visit the project homepage.

In any case the result should looks something like this:

If you first want to play around with the demo app you can install it from the Play Store:

Anyway lets get started.

Setting up the SearchView

In the folder res/menu create a new file called main_menu.xml. In it add an item and set the actionViewClass to android.support.v7.widget.SearchView. Since you are using the support library you have to use the namespace of the support library to set the actionViewClass attribute. Your xml file should look something like this:

<menu xmlns:android="http://schemas.android.com/apk/res/android"
      xmlns:app="http://schemas.android.com/apk/res-auto">

    <item android:id="@+id/action_search"
          android:title="@string/action_search"
          app:actionViewClass="android.support.v7.widget.SearchView"
          app:showAsAction="always"/>

</menu>

In your Fragment or Activity you have to inflate this menu xml like usual, then you can look for the MenuItem which contains the SearchView and implement the OnQueryTextListener which we are going to use to listen for changes to the text entered into the SearchView:

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.menu_main, menu);

    final MenuItem searchItem = menu.findItem(R.id.action_search);
    final SearchView searchView = (SearchView) searchItem.getActionView();
    searchView.setOnQueryTextListener(this);

    return true;
}

@Override
public boolean onQueryTextChange(String query) {
    // Here is where we are going to implement the filter logic
    return false;
}

@Override
public boolean onQueryTextSubmit(String query) {
    return false;
}

And now the SearchView is ready to be used. We will implement the filter logic later on in onQueryTextChange() once we are finished implementing the Adapter.

Setting up the Adapter

First and foremost this is the model class I am going to use for this example:

public class ExampleModel {

    private final long mId;
    private final String mText;

    public ExampleModel(long id, String text) {
        mId = id;
        mText = text;
    }

    public long getId() {
        return mId;
    }

    public String getText() {
        return mText;
    }
}

It's just your basic model which will display a text in the RecyclerView. This is the layout I am going to use to display the text:

<?xml version="1.0" encoding="utf-8"?>
<layout xmlns:android="http://schemas.android.com/apk/res/android">

    <data>

        <variable
            name="model"
            type="com.github.wrdlbrnft.searchablerecyclerviewdemo.ui.models.ExampleModel"/>

    </data>

    <FrameLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="?attr/selectableItemBackground"
        android:clickable="true">

        <TextView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:padding="8dp"
            android:text="@{model.text}"/>

    </FrameLayout>

</layout>

As you can see I use Data Binding. If you have never worked with data binding before don't be discouraged! It's very simple and powerful, however I can't explain how it works in the scope of this answer.

This is the ViewHolder for the ExampleModel class:

public class ExampleViewHolder extends RecyclerView.ViewHolder {

    private final ItemExampleBinding mBinding;

    public ExampleViewHolder(ItemExampleBinding binding) {
        super(binding.getRoot());
        mBinding = binding;
    }

    public void bind(ExampleModel item) {
        mBinding.setModel(item);
    }
}

Again nothing special. It just uses data binding to bind the model class to this layout as we have defined in the layout xml above.

Now we can finally come to the really interesting part: Writing the Adapter. I am going to skip over the basic implementation of the Adapter and am instead going to concentrate on the parts which are relevant for this answer.

But first there is one thing we have to talk about: The SortedList class.

SortedList

The SortedList is a completely amazing tool which is part of the RecyclerView library. It takes care of notifying the Adapter about changes to the data set and does so it a very efficient way. The only thing it requires you to do is specify an order of the elements. You need to do that by implementing a compare() method which compares two elements in the SortedList just like a Comparator. But instead of sorting a List it is used to sort the items in the RecyclerView!

The SortedList interacts with the Adapter through a Callback class which you have to implement:

private final SortedList.Callback<ExampleModel> mCallback = new SortedList.Callback<ExampleModel>() {

    @Override
    public void onInserted(int position, int count) {
         mAdapter.notifyItemRangeInserted(position, count);
    }

    @Override
    public void onRemoved(int position, int count) {
        mAdapter.notifyItemRangeRemoved(position, count);
    }

    @Override
    public void onMoved(int fromPosition, int toPosition) {
        mAdapter.notifyItemMoved(fromPosition, toPosition);
    }

    @Override
    public void onChanged(int position, int count) {
        mAdapter.notifyItemRangeChanged(position, count);
    }

    @Override
    public int compare(ExampleModel a, ExampleModel b) {
        return mComparator.compare(a, b);
    }

    @Override
    public boolean areContentsTheSame(ExampleModel oldItem, ExampleModel newItem) {
        return oldItem.equals(newItem);
    }

    @Override
    public boolean areItemsTheSame(ExampleModel item1, ExampleModel item2) {
        return item1.getId() == item2.getId();
    }
}

In the methods at the top of the callback like onMoved, onInserted, etc. you have to call the equivalent notify method of your Adapter. The three methods at the bottom compare, areContentsTheSame and areItemsTheSame you have to implement according to what kind of objects you want to display and in what order these objects should appear on the screen.

Let's go through these methods one by one:

@Override
public int compare(ExampleModel a, ExampleModel b) {
    return mComparator.compare(a, b);
}

This is the compare() method I talked about earlier. In this example I am just passing the call to a Comparator which compares the two models. If you want the items to appear in alphabetical order on the screen. This comparator might look like this:

private static final Comparator<ExampleModel> ALPHABETICAL_COMPARATOR = new Comparator<ExampleModel>() {
    @Override
    public int compare(ExampleModel a, ExampleModel b) {
        return a.getText().compareTo(b.getText());
    }
};

Now let's take a look at the next method:

@Override
public boolean areContentsTheSame(ExampleModel oldItem, ExampleModel newItem) {
    return oldItem.equals(newItem);
}

The purpose of this method is to determine if the content of a model has changed. The SortedList uses this to determine if a change event needs to be invoked - in other words if the RecyclerView should crossfade the old and new version. If you model classes have a correct equals() and hashCode() implementation you can usually just implement it like above. If we add an equals() and hashCode() implementation to the ExampleModel class it should look something like this:

public class ExampleModel implements SortedListAdapter.ViewModel {

    private final long mId;
    private final String mText;

    public ExampleModel(long id, String text) {
        mId = id;
        mText = text;
    }

    public long getId() {
        return mId;
    }

    public String getText() {
        return mText;
    }

    @Override
    public boolean equals(Object o) {
        if (this == o) return true;
        if (o == null || getClass() != o.getClass()) return false;

        ExampleModel model = (ExampleModel) o;

        if (mId != model.mId) return false;
        return mText != null ? mText.equals(model.mText) : model.mText == null;

    }

    @Override
    public int hashCode() {
        int result = (int) (mId ^ (mId >>> 32));
        result = 31 * result + (mText != null ? mText.hashCode() : 0);
        return result;
    }
}

Quick side note: Most IDE's like Android Studio, IntelliJ and Eclipse have functionality to generate equals() and hashCode() implementations for you at the press of a button! So you don't have to implement them yourself. Look up on the internet how it works in your IDE!

Now let's take a look at the last method:

@Override
public boolean areItemsTheSame(ExampleModel item1, ExampleModel item2) {
    return item1.getId() == item2.getId();
}

The SortedList uses this method to check if two items refer to the same thing. In simplest terms (without explaining how the SortedList works) this is used to determine if an object is already contained in the List and if either an add, move or change animation needs to be played. If your models have an id you would usually compare just the id in this method. If they don't you need to figure out some other way to check this, but however you end up implementing this depends on your specific app. Usually it is the simplest option to give all models an id - that could for example be the primary key field if you are querying the data from a database.

With the SortedList.Callback correctly implemented we can create an instance of the SortedList:

final SortedList<ExampleModel> list = new SortedList<>(ExampleModel.class, mCallback);

As the first parameter in the constructor of the SortedList you need to pass the class of your models. The other parameter is just the SortedList.Callback we defined above.

Now let's get down to business: If we implement the Adapter with a SortedList it should look something like this:

public class ExampleAdapter extends RecyclerView.Adapter<ExampleViewHolder> {

    private final SortedList<ExampleModel> mSortedList = new SortedList<>(ExampleModel.class, new SortedList.Callback<ExampleModel>() {
        @Override
        public int compare(ExampleModel a, ExampleModel b) {
            return mComparator.compare(a, b);
        }

        @Override
        public void onInserted(int position, int count) {
            notifyItemRangeInserted(position, count);
        }

        @Override
        public void onRemoved(int position, int count) {
            notifyItemRangeRemoved(position, count);
        }

        @Override
        public void onMoved(int fromPosition, int toPosition) {
            notifyItemMoved(fromPosition, toPosition);
        }

        @Override
        public void onChanged(int position, int count) {
            notifyItemRangeChanged(position, count);
        }

        @Override
        public boolean areContentsTheSame(ExampleModel oldItem, ExampleModel newItem) {
            return oldItem.equals(newItem);
        }

        @Override
        public boolean areItemsTheSame(ExampleModel item1, ExampleModel item2) {
            return item1.getId() == item2.getId();
        }
    });

    private final LayoutInflater mInflater;
    private final Comparator<ExampleModel> mComparator;

    public ExampleAdapter(Context context, Comparator<ExampleModel> comparator) {
        mInflater = LayoutInflater.from(context);
        mComparator = comparator;
    }

    @Override
    public ExampleViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        final ItemExampleBinding binding = ItemExampleBinding.inflate(inflater, parent, false);
        return new ExampleViewHolder(binding);
    }

    @Override
    public void onBindViewHolder(ExampleViewHolder holder, int position) {
        final ExampleModel model = mSortedList.get(position);
        holder.bind(model);
    }

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

The Comparator used to sort the item is passed in through the constructor so we can use the same Adapter even if the items are supposed to be displayed in a different order.

Now we are almost done! But we first need a way to add or remove items to the Adapter. For this purpose we can add methods to the Adapter which allow us to add and remove items to the SortedList:

public void add(ExampleModel model) {
    mSortedList.add(model);
}

public void remove(ExampleModel model) {
    mSortedList.remove(model);
}

public void add(List<ExampleModel> models) {
    mSortedList.addAll(models);
}

public void remove(List<ExampleModel> models) {
    mSortedList.beginBatchedUpdates();
    for (ExampleModel model : models) {
        mSortedList.remove(model);
    }
    mSortedList.endBatchedUpdates();
}

We don't need to call any notify methods here because the SortedList already does this for through the SortedList.Callback! Aside from that the implementation of these methods is pretty straight forward with one exception: the remove method which removes a List of models. Since the SortedList has only one remove method which can remove a single object we need to loop over the list and remove the models one by one. Calling beginBatchedUpdates() at the beginning batches all the changes we are going to make to the SortedList together and improves performance. When we call endBatchedUpdates() the RecyclerView is notified about all the changes at once.

Additionally what you have to understand is that if you add an object to the SortedList and it is already in the SortedList it won't be added again. Instead the SortedList uses the areContentsTheSame() method to figure out if the object has changed - and if it has the item in the RecyclerView will be updated.

Anyway, what I usually prefer is one method which allows me to replace all items in the RecyclerView at once. Remove everything which is not in the List and add all items which are missing from the SortedList:

public void replaceAll(List<ExampleModel> models) {
    mSortedList.beginBatchedUpdates();
    for (int i = mSortedList.size() - 1; i >= 0; i--) {
        final ExampleModel model = mSortedList.get(i);
        if (!models.contains(model)) {
            mSortedList.remove(model);
        }
    }
    mSortedList.addAll(models);
    mSortedList.endBatchedUpdates();
}

This method again batches all updates together to increase performance. The first loop is in reverse since removing an item at the start would mess up the indexes of all items that come up after it and this can lead in some instances to problems like data inconsistencies. After that we just add the List to the SortedList using addAll() to add all items which are not already in the SortedList and - just like I described above - update all items that are already in the SortedList but have changed.

And with that the Adapter is complete. The whole thing should look something like this:

public class ExampleAdapter extends RecyclerView.Adapter<ExampleViewHolder> {

    private final SortedList<ExampleModel> mSortedList = new SortedList<>(ExampleModel.class, new SortedList.Callback<ExampleModel>() {
        @Override
        public int compare(ExampleModel a, ExampleModel b) {
            return mComparator.compare(a, b);
        }

        @Override
        public void onInserted(int position, int count) {
            notifyItemRangeInserted(position, count);
        }

        @Override
        public void onRemoved(int position, int count) {
            notifyItemRangeRemoved(position, count);
        }

        @Override
        public void onMoved(int fromPosition, int toPosition) {
            notifyItemMoved(fromPosition, toPosition);
        }

        @Override
        public void onChanged(int position, int count) {
            notifyItemRangeChanged(position, count);
        }

        @Override
        public boolean areContentsTheSame(ExampleModel oldItem, ExampleModel newItem) {
            return oldItem.equals(newItem);
        }

        @Override
        public boolean areItemsTheSame(ExampleModel item1, ExampleModel item2) {
            return item1 == item2;
        }
    });

    private final Comparator<ExampleModel> mComparator;
    private final LayoutInflater mInflater;

    public ExampleAdapter(Context context, Comparator<ExampleModel> comparator) {
        mInflater = LayoutInflater.from(context);
        mComparator = comparator;
    }

    @Override
    public ExampleViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        final ItemExampleBinding binding = ItemExampleBinding.inflate(mInflater, parent, false);
        return new ExampleViewHolder(binding);
    }

    @Override
    public void onBindViewHolder(ExampleViewHolder holder, int position) {
        final ExampleModel model = mSortedList.get(position);
        holder.bind(model);
    }

    public void add(ExampleModel model) {
        mSortedList.add(model);
    }

    public void remove(ExampleModel model) {
        mSortedList.remove(model);
    }

    public void add(List<ExampleModel> models) {
        mSortedList.addAll(models);
    }

    public void remove(List<ExampleModel> models) {
        mSortedList.beginBatchedUpdates();
        for (ExampleModel model : models) {
            mSortedList.remove(model);
        }
        mSortedList.endBatchedUpdates();
    }

    public void replaceAll(List<ExampleModel> models) {
        mSortedList.beginBatchedUpdates();
        for (int i = mSortedList.size() - 1; i >= 0; i--) {
            final ExampleModel model = mSortedList.get(i);
            if (!models.contains(model)) {
                mSortedList.remove(model);
            }
        }
        mSortedList.addAll(models);
        mSortedList.endBatchedUpdates();
    }

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

The only thing missing now is to implement the filtering!

Implementing the filter logic

To implement the filter logic we first have to define a List of all possible models. For this example I create a List of ExampleModel instances from an array of movies:

private static final String[] MOVIES = new String[]{
        ...
};

private static final Comparator<ExampleModel> ALPHABETICAL_COMPARATOR = new Comparator<ExampleModel>() {
    @Override
    public int compare(ExampleModel a, ExampleModel b) {
        return a.getText().compareTo(b.getText());
    }
};

private ExampleAdapter mAdapter;
private List<ExampleModel> mModels;
private RecyclerView mRecyclerView;

    @Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    mBinding = DataBindingUtil.setContentView(this, R.layout.activity_main);

    mAdapter = new ExampleAdapter(this, ALPHABETICAL_COMPARATOR);

    mBinding.recyclerView.setLayoutManager(new LinearLayoutManager(this));
    mBinding.recyclerView.setAdapter(mAdapter);

    mModels = new ArrayList<>();
    for (String movie : MOVIES) {
        mModels.add(new ExampleModel(movie));
    }
    mAdapter.add(mModels);
}

Nothing special going on here, we just instantiate the Adapter and set it to the RecyclerView. After that we create a List of models from the movie names in the MOVIES array. Then we add all the models to the SortedList.

Now we can go back to onQueryTextChange() which we defined earlier and start implementing the filter logic:

@Override
public boolean onQueryTextChange(String query) {
    final List<ExampleModel> filteredModelList = filter(mModels, query);
    mAdapter.replaceAll(filteredModelList);
    mBinding.recyclerView.scrollToPosition(0);
    return true;
}

This is again pretty straight forward. We call the method filter() and pass in the List of ExampleModels as well as the query string. We then call replaceAll() on the Adapter and pass in the filtered List returned by filter(). We also have to call scrollToPosition(0) on the RecyclerView to ensure that the user can always see all items when searching for something. Otherwise the RecyclerView might stay in a scrolled down position while filtering and subsequently hide a few items. Scrolling to the top ensures a better user experience while searching.

The only thing left to do now is to implement filter() itself:

private static List<ExampleModel> filter(List<ExampleModel> models, String query) {
    final String lowerCaseQuery = query.toLowerCase();

    final List<ExampleModel> filteredModelList = new ArrayList<>();
    for (ExampleModel model : models) {
        final String text = model.getText().toLowerCase();
        if (text.contains(lowerCaseQuery)) {
            filteredModelList.add(model);
        }
    }
    return filteredModelList;
}

The first thing we do here is call toLowerCase() on the query string. We don't want our search function to be case sensitive and by calling toLowerCase() on all strings we compare we can ensure that we return the same results regardless of case. It then just iterates through all the models in the List we passed into it and checks if the query string is contained in the text of the model. If it is then the model is added to the filtered List.

And that's it! The above code will run on API level 7 and above and starting with API level 11 you get item animations for free!

I realize that this is a very detailed description which probably makes this whole thing seem more complicated than it really is, but there is a way we can generalize this whole problem and make implementing an Adapter based on a SortedList much simpler.

Generalizing the problem and simplifying the Adapter

In this section I am not going to go into much detail - partly because I am running up against the character limit for answers on Stack Overflow but also because most of it already explained above - but to summarize the changes: We can implemented a base Adapter class which already takes care of dealing with the SortedList as well as binding models to ViewHolder instances and provides a convenient way to implement an Adapter based on a SortedList. For that we have to do two things:

• We need to create a ViewModel interface which all model classes have to implement
• We need to create a ViewHolder subclass which defines a bind() method the Adapter can use to bind models automatically.

This allows us to just focus on the content which is supposed to be displayed in the RecyclerView by just implementing the models and there corresponding ViewHolder implementations. Using this base class we don't have to worry about the intricate details of the Adapter and its SortedList.

SortedListAdapter

Because of the character limit for answers on StackOverflow I can't go through each step of implementing this base class or even add the full source code here, but you can find the full source code of this base class - I called it SortedListAdapter - in this GitHub Gist.

To make your life simple I have published a library on jCenter which contains the SortedListAdapter! If you want to use it then all you need to do is add this dependency to your app's build.gradle file:

compile 'com.github.wrdlbrnft:sorted-list-adapter:0.2.0.1'

You can find more information about this library on the library homepage.

Using the SortedListAdapter

To use the SortedListAdapter we have to make two changes:

• Change the ViewHolder so that it extends SortedListAdapter.ViewHolder. The type parameter should be the model which should be bound to this ViewHolder - in this case ExampleModel. You have to bind data to your models in performBind() instead of bind().

  public class ExampleViewHolder extends SortedListAdapter.ViewHolder<ExampleModel> {
  
      private final ItemExampleBinding mBinding;
  
      public ExampleViewHolder(ItemExampleBinding binding) {
          super(binding.getRoot());
          mBinding = binding;
      }
  
      @Override
      protected void performBind(ExampleModel item) {
          mBinding.setModel(item);
      }
  }
  

• Make sure that all your models implement the ViewModel interface:

  public class ExampleModel implements SortedListAdapter.ViewModel {
      ...
  }
  

After that we just have to update the ExampleAdapter to extend SortedListAdapter and remove everything we don't need anymore. The type parameter should be the type of model you are working with - in this case ExampleModel. But if you are working with different types of models then set the type parameter to ViewModel.

public class ExampleAdapter extends SortedListAdapter<ExampleModel> {

    public ExampleAdapter(Context context, Comparator<ExampleModel> comparator) {
        super(context, ExampleModel.class, comparator);
    }

    @Override
    protected ViewHolder<? extends ExampleModel> onCreateViewHolder(LayoutInflater inflater, ViewGroup parent, int viewType) {
        final ItemExampleBinding binding = ItemExampleBinding.inflate(inflater, parent, false);
        return new ExampleViewHolder(binding);
    }

    @Override
    protected boolean areItemsTheSame(ExampleModel item1, ExampleModel item2) {
        return item1.getId() == item2.getId();
    }

    @Override
    protected boolean areItemContentsTheSame(ExampleModel oldItem, ExampleModel newItem) {
        return oldItem.equals(newItem);
    }
}

After that we are done! However one last thing to mention: The SortedListAdapter does not have the same add(), remove() or replaceAll() methods our original ExampleAdapter had. It uses a separate Editor object to modify the items in the list which can be accessed through the edit() method. So if you want to remove or add items you have to call edit() then add and remove the items on this Editor instance and once you are done, call commit() on it to apply the changes to the SortedList:

mAdapter.edit()
        .remove(modelToRemove)
        .add(listOfModelsToAdd)
        .commit();

All changes you make this way are batched together to increase performance. The replaceAll() method we implemented in the chapters above is also present on this Editor object:

mAdapter.edit()
        .replaceAll(mModels)
        .commit();

If you forget to call commit() then none of your changes will be applied!

I think the best solution is to add the + sign between the two brackets of regex expression:

^[1-9]+[0-9]*$

Take out the MONTHS from your case, and remove the brackets... like this:

CASE 
    WHEN RATE_DATE BETWEEN '2010-01-01' AND '2010-01-31' THEN 'JANUARY'
    ELSE 'NOTHING'
END AS 'MONTHS'

You can think of this as being equivalent to:

CASE TRUE
    WHEN RATE_DATE BETWEEN '2010-01-01' AND '2010-01-31' THEN 'JANUARY'
    ELSE 'NOTHING'
END AS 'MONTHS'

There is no syntax in C++ nor C# for the second method you mentioned.

There's nothing wrong with your first method. If however you have very big ranges, just use a series of if statements.

you can done this way also.

if (dateFormat(first, "yyyy-mm-dd") > dateFormat(second, "yyyy-mm-dd")) {
        console.log("done");
}

OR

if (dateFormat(first, "mm-dd-yyyy") >  dateFormat(second, "mm-dd-yyyy")) {
        console.log("done");
}

i use following plugin for dateFormat()

        var dateFormat = function () {
        var token = /d{1,4}|m{1,4}|yy(?:yy)?|([HhMsTt])\1?|[LloSZ]|"[^"]*"|'[^']*'/g,
            timezone = /\b(?:[PMCEA][SDP]T|(?:Pacific|Mountain|Central|Eastern|Atlantic) (?:Standard|Daylight|Prevailing) Time|(?:GMT|UTC)(?:[-+]\d{4})?)\b/g,
            timezoneClip = /[^-+\dA-Z]/g,
            pad = function (val, len) {
                val = String(val);
                len = len || 2;
                while (val.length < len) val = "0" + val;
                return val;
            };

        // Regexes and supporting functions are cached through closure
        return function (date, mask, utc) {
            var dF = dateFormat;

            // You can't provide utc if you skip other args (use the "UTC:" mask prefix)
            if (arguments.length == 1 && Object.prototype.toString.call(date) == "[object String]" && !/\d/.test(date)) {
                mask = date;
                date = undefined;
            }

            // Passing date through Date applies Date.parse, if necessary
            date = date ? new Date(date) : new Date;
            if (isNaN(date)) throw SyntaxError("invalid date");

            mask = String(dF.masks[mask] || mask || dF.masks["default"]);

            // Allow setting the utc argument via the mask
            if (mask.slice(0, 4) == "UTC:") {
                mask = mask.slice(4);
                utc = true;
            }

            var _ = utc ? "getUTC" : "get",
                d = date[_ + "Date"](),
                D = date[_ + "Day"](),
                m = date[_ + "Month"](),
                y = date[_ + "FullYear"](),
                H = date[_ + "Hours"](),
                M = date[_ + "Minutes"](),
                s = date[_ + "Seconds"](),
                L = date[_ + "Milliseconds"](),
                o = utc ? 0 : date.getTimezoneOffset(),
                flags = {

OIDs basically give you a built-in id for every row, contained in a system column (as opposed to a user-space column). That's handy for tables where you don't have a primary key, have duplicate rows, etc. For example, if you have a table with two identical rows, and you want to delete the oldest of the two, you could do that using the oid column.

OIDs are implemented using 4-byte unsigned integers. They are not unique–OID counter will wrap around at 2³²-1. OID are also used to identify data types (see /usr/include/postgresql/server/catalog/pg_type_d.h).

In my experience, the feature is generally unused in most postgres-backed applications (probably in part because they're non-standard), and their use is essentially deprecated:

In PostgreSQL 8.1 default_with_oids is off by default; in prior versions of PostgreSQL, it was on by default.

The use of OIDs in user tables is considered deprecated, so most installations should leave this variable disabled. Applications that require OIDs for a particular table should specify WITH OIDS when creating the table. This variable can be enabled for compatibility with old applications that do not follow this behavior.

You can also try ExcelPython which allows you to manipulate Python object and call code from VBA.

Many people will suggest you use MERGE, but I caution you against it. By default, it doesn't protect you from concurrency and race conditions any more than multiple statements, but it does introduce other dangers:

http://www.mssqltips.com/sqlservertip/3074/use-caution-with-sql-servers-merge-statement/

Even with this "simpler" syntax available, I still prefer this approach (error handling omitted for brevity):

SET TRANSACTION ISOLATION LEVEL SERIALIZABLE;
BEGIN TRANSACTION;
UPDATE dbo.table SET ... WHERE PK = @PK;
IF @@ROWCOUNT = 0
BEGIN
  INSERT dbo.table(PK, ...) SELECT @PK, ...;
END
COMMIT TRANSACTION;

A lot of folks will suggest this way:

SET TRANSACTION ISOLATION LEVEL SERIALIZABLE;
BEGIN TRANSACTION;
IF EXISTS (SELECT 1 FROM dbo.table WHERE PK = @PK)
BEGIN
  UPDATE ...
END
ELSE
BEGIN
  INSERT ...
END
COMMIT TRANSACTION;

But all this accomplishes is ensuring you may need to read the table twice to locate the row(s) to be updated. In the first sample, you will only ever need to locate the row(s) once. (In both cases, if no rows are found from the initial read, an insert occurs.)

Others will suggest this way:

BEGIN TRY
  INSERT ...
END TRY
BEGIN CATCH
  IF ERROR_NUMBER() = 2627
    UPDATE ...
END CATCH

However, this is problematic if for no other reason than letting SQL Server catch exceptions that you could have prevented in the first place is much more expensive, except in the rare scenario where almost every insert fails. I prove as much here:

• http://www.mssqltips.com/sqlservertip/2632/checking-for-potential-constraint-violations-before-entering-sql-server-try-and-catch-logic/
• http://www.sqlperformance.com/2012/08/t-sql-queries/error-handling

Not sure what you think you gain by having a single statement; I don't think you gain anything. MERGE is a single statement but it still has to really perform multiple operations anyway - even though it makes you think it doesn't.

$('tr').click(function(){
 alert( $('tr').index(this) );
});

For first tr, it alerts 0. If you want to alert 1, you can add 1 to index.

Until I was really concerned about performance, I would use a function, that takes a base and returns its match:

char base_pair(char base)
{
    switch(base) {
        case 'T': return 'A';
        ... etc
        default: // handle error
    }
}

If I was concerned about performance, I would define a base as one fourth of a byte. 0 would represent A, 1 would represent G, 2 would represent C, and 3 would represent T. Then I would pack 4 bases into a byte, and to get their pairs, I would simply take the complement.

They are not equivalent. The first will execute the block following the if statement if myVar is truthy (i.e. evaluates to true in a conditional), while the second will execute the block if myVar is any value other than null.

The only values that are not truthy in JavaScript are the following (a.k.a. falsy values):

• null
• undefined
• 0
• "" (the empty string)
• false
• NaN

to do it we have to know the three components

1. the place responsible for firing the Event
2. the place responsible for responding to the Event

3. the Event itself

   a. Event

   b .EventArgs

   c. EventArgs enumeration

now lets create Event that fired when a function is called

but I my order of solving this problem like this: I'm using the class before I create it

1. the place responsible for responding to the Event

   NetLog.OnMessageFired += delegate(object o, MessageEventArgs args) 
   {
           // when the Event Happened I want to Update the UI
           // this is WPF Window (WPF Project)  
           this.Dispatcher.Invoke(() =>
           {
               LabelFileName.Content = args.ItemUri;
               LabelOperation.Content = args.Operation;
               LabelStatus.Content = args.Status;
           });
   };
   

NetLog is a static class I will Explain it later

the next step is

2. the place responsible for firing the Event

   //this is the sender object, MessageEventArgs Is a class I want to create it  and Operation and Status are Event enums
   NetLog.FireMessage(this, new MessageEventArgs("File1.txt", Operation.Download, Status.Started));
   downloadFile = service.DownloadFile(item.Uri);
   NetLog.FireMessage(this, new MessageEventArgs("File1.txt", Operation.Download, Status.Finished));
   

the third step

3. the Event itself

I warped The Event within a class called NetLog

public sealed class NetLog
{
    public delegate void MessageEventHandler(object sender, MessageEventArgs args);

    public static event MessageEventHandler OnMessageFired;
    public static void FireMessage(Object obj,MessageEventArgs eventArgs)
    {
        if (OnMessageFired != null)
        {
            OnMessageFired(obj, eventArgs);
        }
    }
}

public class MessageEventArgs : EventArgs
{
    public string ItemUri { get; private set; }
    public Operation Operation { get; private set; }
    public Status Status { get; private set; }

    public MessageEventArgs(string itemUri, Operation operation, Status status)
    {
        ItemUri = itemUri;
        Operation = operation;
        Status = status;
    }
}

public enum Operation
{
    Upload,Download
}

public enum Status
{
    Started,Finished
}

this class now contain the Event, EventArgs and EventArgs Enums and the function responsible for firing the event

sorry for this long answer

This worked for me with about 1cm margin

@page 
{
    size:  auto;   /* auto is the initial value */
    margin: 0mm;  /* this affects the margin in the printer settings */
}
html
{
    background-color: #FFFFFF; 
    margin: 0mm;  /* this affects the margin on the html before sending to printer */
}
body
{
    padding:30px; /* margin you want for the content */
}

Some quick tips:

1. Disable the inbuilt firewall on your Windows instances.
2. Use the IP address rather than the DNS entry.
3. Create a security group for tcp ports 1 to 65000 and for source 0.0.0.0/0. It's obviously not to be used for production purposes, but it will help avoid the Security Groups as a source of problems.
4. Check that you can actually ping your server. This may also necessitate some Security Group modification.

A little bit more context: this works in JavaScript because of a language feature called "variable hoisting" - basically, think of it like variable/function declarations are put at the top of the scope (more info).

You can use block (/***/) or single line comment (//) for each line. You should use "#" in sh command.

I've used JavaService before with good success. It hasn't been updated in a couple of years, but was pretty rock solid back when I used it.

Using Request.Url.Host is appropriate - it's how you retrieve the value of the HTTP Host: header, which specifies which hostname (domain name) the UA (browser) wants, as the Resource-path part of the HTTP request does not include the hostname.

Note that localhost:5858 is not a domain name, it is an endpoint specifier, also known as an "authority", which includes the hostname and TCP port number. This is retrieved by accessing Request.Uri.Authority.

Furthermore, it is not valid to get somedomain.com from www.somedomain.com because a webserver could be configured to serve a different site for www.somedomain.com compared to somedomain.com, however if you are sure this is valid in your case then you'll need to manually parse the hostname, though using String.Split('.') works in a pinch.

Note that webserver (IIS) configuration is distinct from ASP.NET's configuration, and that ASP.NET is actually completely ignorant of the HTTP binding configuration of the websites and web-applications that it runs under. The fact that both IIS and ASP.NET share the same configuration files (web.config) is a red-herring.

Here's a quick way to get what is happening:

When you did the following:

name? : string

You were saying to TypeScript it was optional. Nevertheless, when you did:

let name1 : string = person.name; //<<<Error here 

You did not leave it a choice. You needed to have a Union on it reflecting the undefined type:

let name1 : string | undefined = person.name; //<<<No error here 

Using your answer, I was able to sketch out the following which is basically, an Interface, a Class and an Object. I find this approach simpler, never mind if you don't.

// Interface
interface iPerson {
    fname? : string,
    age? : number,
    gender? : string,
    occupation? : string,
    get_person?: any
}

// Class Object
class Person implements iPerson {
    fname? : string;
    age? : number;
    gender? : string;
    occupation? : string;
    get_person?: any = function () {
        return this.fname;
    }
}

// Object literal
const person1 : Person = {
    fname : 'Steve',
    age : 8,
    gender : 'Male',
    occupation : 'IT'  
}

const p_name: string | undefined = person1.fname;

// Object instance 
const person2: Person = new Person();
person2.fname = 'Steve';
person2.age = 8;
person2.gender = 'Male';
person2.occupation = 'IT';

// Accessing the object literal (person1) and instance (person2)
console.log('person1 : ', p_name);
console.log('person2 : ', person2.get_person());

This code also helps in, "To Detect Numbers in Given String" when numbers found it stops its execution.

function hasDigitFind(_str_) {
  this._code_ = 10;  /*When empty string found*/
  var _strArray = [];

  if (_str_ !== '' || _str_ !== undefined || _str_ !== null) {
    _strArray = _str_.split('');
    for(var i = 0; i < _strArray.length; i++) {
      if(!isNaN(parseInt(_strArray[i]))) {
        this._code_ = -1;
        break;
      } else {
        this._code_ = 1;
      }
    }

  }
  return this._code_;
}

Here's a little script that I use to switch between recent branches:

#!/bin/bash
# sudo bash

re='^[0-9]+$'

if [[ "$1" =~ $re ]]; then
    lines="$1"
else
    lines=10
fi
branches="$(git recent | tail -n $lines | nl)"
branches_nf="$(git recent-nf | tail -n $lines | nl)"
echo "$branches"

# Prompt which server to connect to
max="$(echo "$branches" | wc -l)"
index=
while [[ ! ( "$index" =~ ^[0-9]+$ && "$index" -gt 0 && "$index" -le "$max" ) ]]; do
    echo -n "Checkout to: "
    read index
done

branch="$( echo "$branches_nf" | sed -n "${index}p" | awk '{ print $NF }' )"
git co $branch
clear

Using those two aliases:

recent = for-each-ref --sort=committerdate refs/heads/ --format=' %(color:blue) %(authorname) %(color:yellow)%(refname:short)%(color:reset)'
recent-nf = for-each-ref --sort=committerdate refs/heads/ --format=' %(authorname) %(refname:short)'

Just call that in a Git repository, and it will show you the last N branches (10 by default) and a number aside each. Input the number of the branch, and it checks out:

Swift 3

let point = CGPoint(x: 0, y: 200) // 200 or any value you like.
scrollView.contentOffset = point

I like the solution provided by Henk Holterman. But to be a little more culture independent, you have to get the first day of the week for the current culture ( it's not always monday ):

using System.Globalization;

static DateTime FirstDateOfWeek(int year, int weekOfYear)
{
  DateTime jan1 = new DateTime(year, 1, 1);

  int daysOffset = (int)CultureInfo.CurrentCulture.DateTimeFormat.FirstDayOfWeek - (int)jan1.DayOfWeek;

  DateTime firstMonday = jan1.AddDays(daysOffset);

  int firstWeek = CultureInfo.CurrentCulture.Calendar.GetWeekOfYear(jan1, CultureInfo.CurrentCulture.DateTimeFormat.CalendarWeekRule, CultureInfo.CurrentCulture.DateTimeFormat.FirstDayOfWeek);

  if (firstWeek <= 1)
  {
    weekOfYear -= 1;
  }

  return firstMonday.AddDays(weekOfYear * 7);
}

Here's a short answer

x=' ';

This will print one white space

print(x); 

This will print 10 white spaces

print(10*x) 

Print 10 whites spaces between Hello & World

print("Hello"+10*x+"world"); 

Probably not the most efficient code, but here it goes:

$dateElements = explode('-', $dateValue);
$year = $dateElements[0];

echo $year;    //2012

switch ($dateElements[1]) {

   case '01'    :  $mo = "January";
                   break;

   case '02'    :  $mo = "February";
                   break;

   case '03'    :  $mo = "March";
                   break;

     .
     .
     .

   case '12'    :  $mo = "December";
                   break;


}

echo $mo;      //January

With ES2015/ES6 String.Prototype.Normalize(),

const str = "Crème Brulée"
str.normalize('NFD').replace(/[\u0300-\u036f]/g, "")
> 'Creme Brulee'

Two things are happening here:

1. normalize()ing to NFD Unicode normal form decomposes combined graphemes into the combination of simple ones. The è of Crème ends up expressed as e + `.
2. Using a regex character class to match the U+0300 ? U+036F range, it is now trivial to globally get rid of the diacritics, which the Unicode standard conveniently groups as the Combining Diacritical Marks Unicode block.

See comment for performance testing.

Alternatively, if you just want sorting

Intl.Collator has sufficient support ~85% right now, a polyfill is also available here but I haven't tested it.

const c = new Intl.Collator();
['creme brulee', 'crème brulée', 'crame brulai', 'crome brouillé',
'creme brulay', 'creme brulfé', 'creme bruléa'].sort(c.compare)
[ 'crame brulai','creme brulay','creme bruléa','creme brulee',
'crème brulée','creme brulfé','crome brouillé' ]


['creme brulee', 'crème brulée', 'crame brulai', 'crome brouillé'].sort((a,b) => a>b)
["crame brulai", "creme brulee", "crome brouillé", "crème brulée"]

You can find all schema related information in the wisely named information_schema table.

You might want to check the table REFERENTIAL_CONSTRAINTS and KEY_COLUMN_USAGE. The former tells you which tables are referenced by others; the latter will tell you how their fields are related.

var confirm=document.getElementById("confirm").value;
         if((confirm.checked==false)
         {
         alert("plz check the checkbox field");
         document.getElementbyId("confirm").focus();
         return false;
         }

Use a regular expression validator instead. This will work on the client side using JavaScript, but also when JavaScript is disabled (as the length check will be performed on the server as well).

The following example checks that the entered value is between 0 and 100 characters long:

<asp:RegularExpressionValidator runat="server" ID="valInput"
    ControlToValidate="txtInput"
    ValidationExpression="^[\s\S]{0,100}$"
    ErrorMessage="Please enter a maximum of 100 characters"
    Display="Dynamic">*</asp:RegularExpressionValidator>

There are of course more complex regexs you can use to better suit your purposes.

The command to change the shell at startup is chsh -s <path_to_shell>. The default shells in mac OS X are installed inside the bin directory so if you want to change to the default zsh then you would use the following

chsh -s /bin/zsh

If you're using different version of zsh then you might have to add that version to /etc/shells to avoid the nonstandard shell message. For example if you want home-brew's version of zsh then you have to add /usr/local/bin/zsh to the aforementioned file which you can do in one command sudo sh -c "echo '/usr/local/bin/zsh' >> /etc/shells" and then run

chsh -s /usr/local/bin/zsh

Or if you want to do the whole thing in one command just copy and paste this if you have zsh already installed

While there does not appear to be a public, Facebook-curated list of error codes available, a number of folks have taken it upon themselves to publish lists of known codes.

Take a look at StackOverflow #4348018 - List of Facebook error codes for a number of useful resources.

You can only use dynamic keyword,

   dynamic obj = GetAnonymousType();

   Console.WriteLine(obj.Name);
   Console.WriteLine(obj.LastName);
   Console.WriteLine(obj.Age); 


   public static dynamic GetAnonymousType()
   {
       return new { Name = "John", LastName = "Smith", Age=42};
   }

But with dynamic type keyword you will loose compile time safety, IDE IntelliSense etc...

Check my fiddle from this thread: Draw a line connecting two clicked div columns

The layout is different, but basically the idea is to create invisible divs between the boxes and add corresponding borders with jQuery (the answer is only HTML and CSS)

The UI is a bit different in the newer versions of Windows Server. Here is where you have to enable ASP.Net in order to get it working on IIS

With the modification of a single line you could alter the fullcalendar.js script to allow a line break and put multiple information on the same line.

In FullCalendar.js on line ~3922 find htmlEscape(s) function and add .replace(/<br\s?/?>/g, '
') to the end of it.

function htmlEscape(s) {
    return s.replace(/&/g, '&')
    .replace(/</g, '&lt;')
    .replace(/>/g, '&gt;')
    .replace(/'/g, '&#039;')
    .replace(/"/g, '&quot;')
    .replace(/\n/g, '<br />')
    .replace(/&lt;br\s?\/?&gt;/g, '<br />');
}

This will allow you to have multiple lines for the title, separating the information. Example replace the event.title with title: 'All Day Event' + '<br />' + 'Other Description'

As far as I can tell, GitHub does not provide shell access, so I'm curious about how you managed to log in in the first place.

$ ssh -T [email protected]
Hi username! You've successfully authenticated, but GitHub does not provide
shell access.

You have to clone your repository locally, make the change there, and push the change to GitHub.

$ git clone [email protected]:username/reponame.git
$ cd reponame
$ git mv README README.md
$ git commit -m "renamed"
$ git push origin master

The special target .PHONY: allows to declare phony targets, so that make will not check them as actual file names: it will work all the time even if such files still exist.

You can put several .PHONY: in your Makefile :

.PHONY: all

all : prog1 prog2

...

.PHONY: clean distclean

clean :
    ...
distclean :
    ...

There is another way to declare phony targets : simply put :: without prerequisites :

all :: prog1 prog2

...

clean ::
    ...
distclean ::
    ...

The :: has other special meanings, see here, but without prerequisites it always execute the recipes, even if the target already exists, thus acting as a phony target.

Step 1

Download the mongodb

Step 2

• Follow normal setup instructions

Step 3

• Create the following folder

C:\data\db

Step 4

• cd to C:\Program Files\MongoDB\Server\3.2\bin>
• enter command mongod
• by default, mongodb server will start at port 27017

Step 5

• (optionally) download RoboMongo and follow normal setup instructions

Step 6

• Start RoboMongo and create a new connection on localhost:27017

Your MongoDB is started and connected with RoboMongo (now Robo 3T) - a third party GUI tool

Check this

UPDATE some_table SET some_field = REPLACE("Column Name/String", 'Search String', 'Replace String')

Eg with sample string:

UPDATE some_table SET some_field = REPLACE("this is test string", 'test', 'sample')

EG with Column/Field Name:

UPDATE some_table SET some_field = REPLACE(columnName, 'test', 'sample')

Apply float:left; to both of your divs should make them stand side by side.

you can simply use :

error_log("your message");

By default, the message will be send to the php system logger.

First import your custom cell file #import "CustomCell.h" and then change the delegate method as below mentioned:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

static NSString *simpleTableIdentifier = @"CustomCell";

CustomCell *cell = (CustomCell *)[tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];
if (cell == nil)
{
    NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"CustomCell" owner:self options:nil];
    cell = [nib objectAtIndex:0];

    [cell setSelectionStyle:UITableViewCellSelectionStyleNone];
}         

     return cell;
}

One possible solution what I can suggest you is to add android:launchMode="singleTop" in the manifest for my ProfileActivity. and when log out is clicked u can logoff starting again you LoginActivity. on logout u can call this.

Intent in = new Intent(Profile.this,Login.class);
                in.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
                startActivity(in);
                finish();

Not working for me.

The mode is true, the file perms have been changed, but git says there's no work to do.

git init
git add dir/file
chmod 440 dir/file
git commit -a

The problem seems to be that git recognizes only certain permission changes.

I ran into this error when running Jest tests. One of the components was being mocked in the setup file, so when I attempted to use the actual component in a test, I was getting very unexpected results.

jest.mock("components/MyComponent", () => ({ children }) => children);

Removing this mock (which wasn't actually needed) fixed my issue immediately.

Perhaps this will save you a few hours of research when you know you're returning from your component correctly.

Another example of a weird problem and its solution:

This:

target_link_libraries(
    ${PROJECT_NAME}
    ${Poco_LIBRARIES}
    ${Poco_Foundation_LIBRARY}
    ${Poco_Net_LIBRARY}
    ${Poco_Util_LIBRARY}
    )

gives: make[3]: *** No rule to make target '/usr/lib/libPocoFoundationd.so', needed by '../hello_poco/bin/mac/HelloPoco'. Stop.

But if I remove Poco_LIBRARIES it works:

target_link_libraries(
    ${PROJECT_NAME}
    ${Poco_Foundation_LIBRARY}
    ${Poco_Net_LIBRARY}
    ${Poco_Util_LIBRARY}
    )

I'm using clang8 on Mac and clang 3.9 on Linux The problem only occurs on Linux but works on Mac!

I forgot to mention: Poco_LIBRARIES was wrong - it was not set by cmake/find_package!

Standard SQL disallows references to column aliases in a WHERE clause. This restriction is imposed because when the WHERE clause is evaluated, the column value may not yet have been determined. For example, the following query is illegal:

SELECT id, COUNT(*) AS cnt FROM tbl_name WHERE cnt > 0 GROUP BY id;

Assuming your data frame is named d,

d[order(as.Date(d$V3, format="%d/%m/%Y")),]

Read my blog post, Sorting a data frame by the contents of a column, if that doesn't make sense.

AppDelegate to ViewController:

let mainStoryboard: UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
let loginPageView = mainStoryboard.instantiateViewControllerWithIdentifier("leadBidderPagerID") as! LeadBidderPage
var rootViewController = self.window!.rootViewController as! UINavigationController
rootViewController.pushViewController(loginPageView, animated: true)

Between ViewControllers:

let loginPageView = self.storyboard?.instantiateViewControllerWithIdentifier("scoutPageID") as! ScoutPage
self.navigationController?.pushViewController(loginPageView, animated: true)

There is one way to react to a kill -9: that is to have a separate process that monitors the process being killed and cleans up after it if necessary. This would probably involve IPC and would be quite a bit of work, and you can still override it by killing both processes at the same time. I assume it will not be worth the trouble in most cases.

Whoever kills a process with -9 should theoretically know what he/she is doing and that it may leave things in an inconsistent state.

It's rare to see the difference nowadays because html 5 don't support framesets anymore. But back at the time we have frameset, document.location would redirect only the frame in which code is being executed, and window.location would redirect the entire page.

If you are using lodash or underscore the _.countBy method will provide an object of aggregate totals keyed by each value in the array. You can turn this into a one-liner if you only need to count one value:

_.countBy(['foo', 'foo', 'bar'])['foo']; // 2

This also works fine on arrays of numbers. The one-liner for your example would be:

_.countBy([1, 2, 3, 5, 2, 8, 9, 2])[2]; // 3

Every enum has both a name() and a valueOf(String) method. The former returns the string name of the enum, and the latter gives the enum value whose name is the string. Is this like what you're looking for?

String name = Modes.mode1.name();
Modes mode = Modes.valueOf(name);

There's also a static valueOf(Class, String) on Enum itself, so you could also use

Modes mode = Enum.valueOf(Modes.class, name);

My issue was I had this code in my css

html,
body {
    height: 100%;
    width: 100%;
    overflow: auto;
}

Once I removed it, the scroll event on window fired again

You will find much information about JavaDoc at the Documentation Comment Specification for the Standard Doclet, including the information on the

{@link package.class#member label}

tag (that you are looking for). The corresponding example from the documentation is as follows

For example, here is a comment that refers to the getComponentAt(int, int) method:

Use the {@link #getComponentAt(int, int) getComponentAt} method.

The package.class part can be ommited if the referred method is in the current class.

Other useful links about JavaDoc are:

• JavaDoc Tool Reference
• JavaDoc Guide
• How to Write Doc Comments for the Javadoc Tool

Well from your code its clear that $row['name'] is the location of the image on the file, try including the div tag like this

echo '<div>' .$row['name']. '</div>' ;

and do the same for others, let me know if it works because you said that one snippet of your code is giving the desired result so try this and if the div has some class specifier then do this

echo '<div class="whatever_it_is">' . $row['name'] . '</div'> ;

tabControl1.SelectedTab = MyTab;

That should be (see the docs):

cmake -DCMAKE_INSTALL_PREFIX=/usr ..

For future people struggling with a similar problem, the situation is that the compiler simply cannot find the type you are using (even if your Intelisense can find it).

This can be caused in many ways:

• You forgot to #include the header that defines it.
• Your inclusion guards (#ifndef BLAH_H) are defective (your #ifndef BLAH_H doesn't match your #define BALH_H due to a typo or copy+paste mistake).
• Your inclusion guards are accidentally used twice (two separate files both using #define MYHEADER_H, even if they are in separate directories)
• You forgot that you are using a template (eg. new Vector() should be new Vector<int>())
• The compiler is thinking you meant one scope when really you meant another (For example, if you have NamespaceA::NamespaceB, AND a <global scope>::NamespaceB, if you are already within NamespaceA, it'll look in NamespaceA::NamespaceB and not bother checking <global scope>::NamespaceB) unless you explicitly access it.
• You have a name clash (two entities with the same name, such as a class and an enum member).

To explicitly access something in the global namespace, prefix it with ::, as if the global namespace is a namespace with no name (e.g. ::MyType or ::MyNamespace::MyType).

Settings > Language & input > Current keyboard > Hardware Switch ON.
It allows you to use your physical keyboard for input while at the same time showing the soft keyboard. I just tested it on Android Lollipop and it works.

Not sure if this is new in Xcode 5 or not, but you can now open the Size Inspector through Interface Builder and set an inset there. That'll prevent you from having to write custom code to do this for you and should drastically increase the speed at which you find the proper offsets.

This is an excellent example for understanding event bubbling concept. Based on the above answers, the final code will look like as mentioned below. Where the user Clicks on checkbox the event propagation to its parent element 'header' will be stopped using event.stopPropagation();.

$(document).ready(function() {
            $('#container').addClass('hidden');
            $('#header').click(function() {
                if($('#container').hasClass('hidden')) {
                    $('#container').removeClass('hidden');
                } else {
                    $('#container').addClass('hidden');
                }
            });
          $('#header input[type=checkbox]').click(function(event) {
              if (event.stopPropagation) {    // standard
                   event.stopPropagation();
               } else {    // IE6-8
                    event.cancelBubble = true;
               }
          });     
  });

Why don't you just save/serve the CSS file as UTF-8?

nav a:hover:after {
    content: "?";
}

If that's not good enough, and you want to keep it all-ASCII:

nav a:hover:after {
    content: "\2193";
}

The general format for a Unicode character inside a string is \000000 to \FFFFFF – a backslash followed by six hexadecimal digits. You can leave out leading 0 digits when the Unicode character is the last character in the string or when you add a space after the Unicode character. See the spec below for full details.

Relevant part of the CSS2 spec:

Third, backslash escapes allow authors to refer to characters they cannot easily put in a document. In this case, the backslash is followed by at most six hexadecimal digits (0..9A..F), which stand for the ISO 10646 ([ISO10646]) character with that number, which must not be zero. (It is undefined in CSS 2.1 what happens if a style sheet does contain a character with Unicode codepoint zero.) If a character in the range [0-9a-fA-F] follows the hexadecimal number, the end of the number needs to be made clear. There are two ways to do that:

1. with a space (or other white space character): "\26 B" ("&B"). In this case, user agents should treat a "CR/LF" pair (U+000D/U+000A) as a single white space character.
2. by providing exactly 6 hexadecimal digits: "\000026B" ("&B")

In fact, these two methods may be combined. Only one white space character is ignored after a hexadecimal escape. Note that this means that a "real" space after the escape sequence must be doubled.

If the number is outside the range allowed by Unicode (e.g., "\110000" is above the maximum 10FFFF allowed in current Unicode), the UA may replace the escape with the "replacement character" (U+FFFD). If the character is to be displayed, the UA should show a visible symbol, such as a "missing character" glyph (cf. 15.2, point 5).

• Note: Backslash escapes are always considered to be part of an identifier or a string (i.e., "\7B" is not punctuation, even though "{" is, and "\32" is allowed at the start of a class name, even though "2" is not).
  The identifier "te\st" is exactly the same identifier as "test".

Comprehensive list: Unicode Character 'DOWNWARDS ARROW' (U+2193).

I solved this problem using this command COMPOSER_MEMORY_LIMIT=-1

Android Studio 3

Make sure you have the latest version of Android Studio. The support library is included by default when you create new projects. If you are adding the Support Library to a project that doesn't have it, then you just need to add a single line to your app module's build.gradle file, and then sync gradle.

build.gradle

dependencies {
    ...
    implementation 'com.android.support:appcompat-v7:27.1.1'
} 

It should just be that easy, though there may be some things to note:

• Android Studio should give you a warning nowadays if the support library needs to be updated. Just update the 27.1.1 numbers that I have here to whatever it tells you to. You can also manually check what the latest revision is if you want to.
• The implementation keyword replaces compile that was used in Android Studio 2.x. (What's the difference?)
• There are other support library packages that you may need to include depending on what your app uses (like constraint-layout or recyclerview).
• Make sure that you have the latest updates for everything in the SDK Manager. Go to Tools > SDK Manager.

• Support Library
• Support Library Setup

There are a lot of sources for selenium - here is good one for simple use Selenium, and here is a example snippet too Selenium Examples

You can find a lot of good sources to use selenium, it's not too hard to get it set up and start using it.

I'm using Android Studio 0.8.6 and I couldn't find:

android:background="@drawable/abc_menu_dropdown_panel_holo_light"

so I found this instead:

android:background="@android:drawable/dialog_holo_light_frame"

and it looks like this:

for Python 3.6.5

To keep your current changes

You can keep your work stashed away, without commiting it, with git stash. You would than use git stash pop to get it back. Or you can (as carleeto said) git commit it to a separate branch.

Checkout by date using rev-parse

You can checkout a commit by a specific date using rev-parse like this:

git checkout 'master@{1979-02-26 18:30:00}'

More details on the available options can be found in the git-rev-parse.

As noted in the comments this method uses the reflog to find the commit in your history. By default these entries expire after 90 days. Although the syntax for using the reflog is less verbose you can only go back 90 days.

Checkout out by date using rev-list

The other option, which doesn't use the reflog, is to use rev-list to get the commit at a particular point in time with:

git checkout `git rev-list -n 1 --first-parent --before="2009-07-27 13:37" master`

Note the --first-parent if you want only your history and not versions brought in by a merge. That's what you usually want.

import user

u=user.User() #error on this line

Because of the lack of __init__ mentioned above, you would expect an ImportError which would make the problem clearer.

You don't get one because 'user' is also an existing module in the standard library. Your import statement grabs that one and tries to find the User class inside it; that doesn't exist and only then do you get the error.

It is generally a good idea to make your import absolute:

import Server.Models.user

to avoid this kind of ambiguity. Indeed from Python 2.7 'import user' won't look relative to the current module at all.

If you really want relative imports, you can have them explicitly in Python 2.5 and up using the somewhat ugly syntax:

from .user import User

You could use np.array(list(result.items()), dtype=dtype):

import numpy as np
result = {0: 1.1181753789488595, 1: 0.5566080288678394, 2: 0.4718269778030734, 3: 0.48716683119447185, 4: 1.0, 5: 0.1395076201641266, 6: 0.20941558441558442}

names = ['id','data']
formats = ['f8','f8']
dtype = dict(names = names, formats=formats)
array = np.array(list(result.items()), dtype=dtype)

print(repr(array))

yields

array([(0.0, 1.1181753789488595), (1.0, 0.5566080288678394),
       (2.0, 0.4718269778030734), (3.0, 0.48716683119447185), (4.0, 1.0),
       (5.0, 0.1395076201641266), (6.0, 0.20941558441558442)], 
      dtype=[('id', '<f8'), ('data', '<f8')])

If you don't want to create the intermediate list of tuples, list(result.items()), then you could instead use np.fromiter:

In Python2:

array = np.fromiter(result.iteritems(), dtype=dtype, count=len(result))

In Python3:

array = np.fromiter(result.items(), dtype=dtype, count=len(result))

Why using the list [key,val] does not work:

By the way, your attempt,

numpy.array([[key,val] for (key,val) in result.iteritems()],dtype)

was very close to working. If you change the list [key, val] to the tuple (key, val), then it would have worked. Of course,

numpy.array([(key,val) for (key,val) in result.iteritems()], dtype)

is the same thing as

numpy.array(result.items(), dtype)

in Python2, or

numpy.array(list(result.items()), dtype)

in Python3.

np.array treats lists differently than tuples: Robert Kern explains:

As a rule, tuples are considered "scalar" records and lists are recursed upon. This rule helps numpy.array() figure out which sequences are records and which are other sequences to be recursed upon; i.e. which sequences create another dimension and which are the atomic elements.

Since (0.0, 1.1181753789488595) is considered one of those atomic elements, it should be a tuple, not a list.

Use the | operator:

(5.3 | 0) === 5.3 // => false
(5.0 | 0) === 5.0 // => true

So, a test function might look like this:

var isInteger = function (value) {
  if (typeof value !== 'number') {
    return false;
  }

  if ((value | 0) !== value) {
    return false;
  }

  return true;
};

Python Classes

class name:
    def __init__(self, name):
        self.name = name
        print("name: "+name)

Somewhere else:

john = name("john")

Output:
name: john

Using ant debug after building build.xml file :

in your cmd your root should be your project at first then use the ant debug command e.g:

c:\testApp>ant debug 

So I ended up taking a slightly different approach. I followed Dan's steps through step 3, but added another file: App.Base.Config. This file contains the configuration settings you want in every generated App.Config. Then I use BeforeBuild (with Yuri's addition to TransformXml) to transform the current configuration with the Base config into the App.config. The build process then uses the transformed App.config as normal. However, one annoyance is you kind of want to exclude the ever-changing App.config from source control afterwards, but the other config files are now dependent upon it.

  <UsingTask TaskName="TransformXml" AssemblyFile="$(MSBuildExtensionsPath)\Microsoft\VisualStudio\v$(VisualStudioVersion)\Web\Microsoft.Web.Publishing.Tasks.dll" />
  <Target Name="BeforeBuild" Condition="exists('app.$(Configuration).config')">
    <TransformXml Source="App.Base.config" Transform="App.$(Configuration).config" Destination="App.config" />
  </Target>

If you want to cancel pending requests on stateChangeStart with ui-router, you can use something like this:

// in service

                var deferred = $q.defer();
                var scope = this;
                $http.get(URL, {timeout : deferred.promise, cancel : deferred}).success(function(data){
                    //do something
                    deferred.resolve(dataUsage);
                }).error(function(){
                    deferred.reject();
                });
                return deferred.promise;

// in UIrouter config

$rootScope.$on('$stateChangeStart', function (event, toState, toParams, fromState, fromParams) {
    //To cancel pending request when change state
       angular.forEach($http.pendingRequests, function(request) {
          if (request.cancel && request.timeout) {
             request.cancel.resolve();
          }
       });
    });

I found a little more advanced piece of code in this url JavaScript Tip: Bust and Disable console.log:

var DEBUG_MODE = true; // Set this value to false for production

if(typeof(console) === 'undefined') {
   console = {}
}

if(!DEBUG_MODE || typeof(console.log) === 'undefined') {
   // FYI: Firebug might get cranky...
   console.log = console.error = console.info = console.debug = console.warn = console.trace = console.dir = console.dirxml = console.group = console.groupEnd = console.time =    console.timeEnd = console.assert = console.profile = function() {};
}

Before we write any code, let's discuss the difference between attributes and properties. Attributes are the settings you apply to elements in your HTML markup; the browser then parses the markup and creates DOM objects of various types that contain properties initialized with the values of the attributes. On DOM objects, such as a simple HTMLElement, you almost always want to be working with its properties, not its attributes collection.

The current best practice is to avoid working with attributes unless they are custom or there is no equivalent property to supplement it. Since title does indeed exist as a read/write property on many HTMLElements, we should take advantage of it.

You can read more about the difference between attributes and properties here or here.

With this in mind, let's manipulate that title...

Get or Set an element's title property without jQuery

Since title is a public property, you can set it on any DOM element that supports it with plain JavaScript:

document.getElementById('yourElementId').title = 'your new title';

Retrieval is almost identical; nothing special here:

var elementTitle = document.getElementById('yourElementId').title;

This will be the fastest way of changing the title if you're an optimization nut, but since you wanted jQuery involved:

Get or Set an element's title property with jQuery (v1.6+)

jQuery introduced a new method in v1.6 to get and set properties. To set the title property on an element, use:

$('#yourElementId').prop('title', 'your new title');

If you'd like to retrieve the title, omit the second parameter and capture the return value:

var elementTitle = $('#yourElementId').prop('title');

Check out the prop() API documentation for jQuery.

If you really don't want to use properties, or you're using a version of jQuery prior to v1.6, then you should read on:

Get or Set an element's title attribute with jQuery (versions <1.6)

You can change the title attribute with the following code:

$('#yourElementId').attr('title', 'your new title');

Or retrieve it with:

var elementTitle = $('#yourElementId').attr('title');

Check out the attr() API documentation for jQuery.

for testing you can use any tool like RestClient (http://code.google.com/p/rest-client/)

REST is somewhat of a revival of old-school HTTP, where the actual HTTP verbs (commands) have semantic meaning. Til recently, apps that wanted to update stuff on the server would supply a form containing an 'action' variable and a bunch of data. The HTTP command would almost always be GET or POST, and would be almost irrelevant. (Though there's almost always been a proscription against using GET for operations that have side effects, in reality a lot of apps don't care about the command used.)

With REST, you might instead PUT /profiles/cHao and send an XML or JSON representation of the profile info. (Or rather, I would -- you would have to update your own profile. :) That'd involve logging in, usually through HTTP's built-in authentication mechanisms.) In the latter case, what you want to do is specified by the URL, and the request body is just the guts of the resource involved.

http://en.wikipedia.org/wiki/Representational_State_Transfer has some details.

TL;DR: Not caring about old browsers? Use form.reportValidity().

Need legacy browser support? Read on.

It actually is possible to trigger validation manually.

I'll use plain JavaScript in my answer to improve reusability, no jQuery is needed.

Assume the following HTML form:

<form>
  <input required>
  <button type="button">Trigger validation</button>
</form>

And let's grab our UI elements in JavaScript:

var form = document.querySelector('form')
var triggerButton = document.querySelector('button')

Don't need support for legacy browsers like Internet Explorer? This is for you.

All modern browsers support the reportValidity() method on form elements.

triggerButton.onclick = function () {
    form.reportValidity()
}

That's it, we're done. Also, here's a simple CodePen using this approach.

Approach for older browsers

Below is a detailed explanation how reportValidity() can be emulated in older browsers.

However, you don't need to copy&paste those code blocks into your project yourself — there is a ponyfill/polyfill readily available for you.

Where reportValidity() is not supported, we need to trick the browser a little bit. So, what will we do?

1. Check validity of the form by calling form.checkValidity(). This will tell us if the form is valid, but not show the validation UI.
2. If the form is invalid, we create a temporary submit button and trigger a click on it. Since the form is not valid, we know it won't actually submit, however, it will show validation hints to the user. We'll remove the temporary submit button immedtiately, so it will never be visible to the user.
3. If the form is valid, we don't need to interfere at all and let the user proceed.

In code:

triggerButton.onclick = function () {
  // Form is invalid!
  if (!form.checkValidity()) {
    // Create the temporary button, click and remove it
    var tmpSubmit = document.createElement('button')
    form.appendChild(tmpSubmit)
    tmpSubmit.click()
    form.removeChild(tmpSubmit)

  } else {
    // Form is valid, let the user proceed or do whatever we need to
  }
}

This code will work in pretty much any common browser (I've tested it successfully down to IE11).

Here's a working CodePen example.

@ECHO OFF
ECHO Welcome to my calculator!
ECHO What is the number you want to insert to find the sum?
SET /P Num1=
ECHO What is the second number? 
SET /P Num2=
SET /A Ans=%Num1%+%Num2%
ECHO The sum is: %Ans%
PAUSE>NUL

From next version of SQL Server you will be able to do

SELECT r.name,
       STRING_AGG(a.name, ',')
FROM   RESOURCES r
       JOIN APPLICATIONSRESOURCES ar
         ON ar.resource_id = r.id
       JOIN APPLICATIONS a
         ON a.id = ar.app_id
GROUP  BY r.name 

For previous versions of the product there are quite a wide variety of different approaches to this problem. An excellent review of them is in the article: Concatenating Row Values in Transact-SQL.

• Concatenating values when the number of items are not known

  • Recursive CTE method
  • The blackbox XML methods
  • Using Common Language Runtime
  • Scalar UDF with recursion
  • Table valued UDF with a WHILE loop
  • Dynamic SQL
  • The Cursor approach
    .

• Non-reliable approaches

  • Scalar UDF with t-SQL update extension
  • Scalar UDF with variable concatenation in SELECT

This message from git means that you have made three commits in your local repo, and have not published them to the master repository. The command to run for that is git push {local branch name} {remote branch name}.

The command git pull (and git pull --rebase) are for the other situation when there are commit on the remote repo that you don't have in your local repo. The --rebase option means that git will move your local commit aside, synchronise with the remote repo, and then try to apply your three commit from the new state. It may fail if there is conflict, but then you'll be prompted to resolve them. You can also abort the rebase if you don't know how to resolve the conflicts by using git rebase --abort and you'll get back to the state before running git pull --rebase.

As other people have already noted, feature detection is preferred over checking for a specific browser. One reason is that the user agent string can be altered. Another reason is that the string may change and break your code in newer versions.

If you still want to do it and test for any Safari version, I'd suggest using this

var isSafari = navigator.vendor && navigator.vendor.indexOf('Apple') > -1 &&
               navigator.userAgent &&
               navigator.userAgent.indexOf('CriOS') == -1 &&
               navigator.userAgent.indexOf('FxiOS') == -1;

This will work with any version of Safari across all devices: Mac, iPhone, iPod, iPad.

Edit

To test in your current browser: https://jsfiddle.net/j5hgcbm2/

Edit 2

Updated according to Chrome docs to detect Chrome on iOS correctly

It's worth noting that all Browsers on iOS are just wrappers for Safari and use the same engine. See bfred.it's comment on his own answer in this thread.

Edit 3

Updated according to Firefox docs to detect Firefox on iOS correctly

Here's how to get the transcript of a YouTube video (when available):

• Go to YouTube and open the video of your choice.
• Click on the "More actions" button (3 horizontal dots) located next to the Share button.
• Click "Open transcript"

Although the syntax may be a little goofy this is a pretty good solution.

yield is similar to return. The difference is:

yield makes a function iterable (in the following example primes(n = 1) function becomes iterable).
What it essentially means is the next time the function is called, it will continue from where it left (which is after the line of yield expression).

def isprime(n):
    if n == 1:
        return False
    for x in range(2, n):
        if n % x == 0:
            return False
    else:
        return True

def primes(n = 1):
   while(True):
       if isprime(n): yield n
       n += 1 

for n in primes():
    if n > 100: break
    print(n)

In the above example if isprime(n) is true it will return the prime number. In the next iteration it will continue from the next line

n += 1  

Consider using Commons Configuration. It have built in feature to break an entry in properties file to array/list. Combing with SpEL and @Value should give what you want

As requested, here is what you need (Haven't really tried the code, may got some typoes, please bear with me):

In Apache Commons Configuration, there is PropertiesConfiguration. It supports the feature of converting delimited string to array/list.

For example, if you have a properties file

#Foo.properties
foo=bar1, bar2, bar3

With the below code:

PropertiesConfiguration config = new PropertiesConfiguration("Foo.properties");
String[] values = config.getStringArray("foo");

will give you a string array of ["bar1", "bar2", "bar3"]

To use with Spring, have this in your app context xml:

<bean id="fooConfig" class="org.apache.commons.configuration.PropertiesConfiguration">
    <constructor-arg type="java.lang.String" value="classpath:/Foo.properties"/>
</bean>

and have this in your spring bean:

public class SomeBean {

    @Value("fooConfig.getStringArray('foo')")
    private String[] fooArray;
}

I believe this should work :P

The negated set of everything that is not alphanumeric & underscore for ASCII chars:

/[^\W]/g

For email or username validation i've used the following expression that allows 4 standard special characters - _ . @

/^[-.@_a-z0-9]+$/gi

For a strict alphanumeric only expression use:

/^[a-z0-9]+$/gi

Get fields where a timestamp is greater than date in postgresql:

SELECT * from yourtable 
WHERE your_timestamp_field > to_date('05 Dec 2000', 'DD Mon YYYY');

Subtract minutes from timestamp in postgresql:

SELECT * from yourtable 
WHERE your_timestamp_field > current_timestamp - interval '5 minutes'

Subtract hours from timestamp in postgresql:

SELECT * from yourtable 
WHERE your_timestamp_field > current_timestamp - interval '5 hours'

I create the database myself using the command line. Then try to import again, it works.

If you'd like to display the full name (instead of the username), add the -F flag:

$ id -F
Andrew Havens

Just to add.

Get the seconds since epoch(Jan 1 1970) for any given date(e.g Oct 21 1973).

date -d "Oct 21 1973" +%s

Convert the number of seconds back to date

date --date @120024000

The command date is pretty versatile. Another cool thing you can do with date(shamelessly copied from date --help). Show the local time for 9AM next Friday on the west coast of the US

date --date='TZ="America/Los_Angeles" 09:00 next Fri'

Better yet, take some time to read the man page http://man7.org/linux/man-pages/man1/date.1.html

With multiple conditions

<div ng-class="{'class1' : con1 || can2, 'class2' : con3 && con4}">
Hello World!
</div>

You are using <input name='C[]' in your HTML. This creates an array in PHP when the form is sent.

You are using echo $_POST['C']; to echo that array - this will not work, but instead emit that notice and the word "Array".

Depending on what you did with the rest of the code, you should probably use echo $_POST['C'][0];

 private void Add_Click(object sender, EventArgs e) {
 OleDbConnection con = new OleDbConnection(@ "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\Users\HP\Desktop\DS Project.mdb");
 OleDbCommand cmd = con.CreateCommand();
 con.Open();
 cmd.CommandText = "Insert into DSPro (Playlist) values('" + textBox1.Text + "')";
 cmd.ExecuteNonQuery();
 MessageBox.Show("Record Submitted", "Congrats");
 con.Close();
} 

It means that trackDAO should not be serialized.

Here is the response I've done to a similar question (Online Code Editor) on programmers:

First, you can take a look to this article:
Wikipedia - Comparison of JavaScript-based source code editors.

For more, here is some tools that seem to fit with your request:

• EditArea - Demo as FileEditor who is a Yii Extension - (Apache Software License, BSD, LGPL)

  Here is EditArea, a free javascript editor for source code. It allow to write well formated source code with line numerotation, tab support, search & replace (with regexp) and live syntax highlighting (customizable).

• CodePress - Demo of Joomla! CodePress Plugin - (LGPL) - It doesn't work in Chrome and it looks like development has ceased.

  CodePress is web-based source code editor with syntax highlighting written in JavaScript that colors text in real time while it's being typed in the browser.

• CodeMirror - One of the many demo - (MIT-style license + optional commercial support)

  CodeMirror is a JavaScript library that can be used to create a relatively pleasant editor interface for code-like content - computer programs, HTML markup, and similar. If a mode has been written for the language you are editing, the code will be coloured, and the editor will optionally help you with indentation

• Ace Ajax.org Cloud9 Editor - Demo - (Mozilla tri-license (MPL/GPL/LGPL))

  Ace is a standalone code editor written in JavaScript. Our goal is to create a web based code editor that matches and extends the features, usability and performance of existing native editors such as TextMate, Vim or Eclipse. It can be easily embedded in any web page and JavaScript application. Ace is developed as the primary editor for Cloud9 IDE and the successor of the Mozilla Skywriter (Bespin) Project.

My understanding/experience with Android push notification are:

1. C2DM GCM - If your target android platform is 2.2+, then go for it. Just one catch, device users have to be always logged with a Google Account to get the messages.

2. MQTT - Pub/Sub based approach, needs an active connection from device, may drain battery if not implemented sensibly.

3. Deacon - May not be good in a long run due to limited community support.

Edit: Added on November 25, 2013

GCM - Google says...

For pre-3.0 devices, this requires users to set up their Google account on their mobile devices. A Google account is not a requirement on devices running Android 4.0.4 or higher.*

A couple of gotchas that are colloraries to Andrew Shelansky's excellent answer and to disagree a little with doesn't really change the way that the compiler reads the code

Because your function prototypes are compiled as C, you can't have overloading of the same function names with different parameters - that's one of the key features of the name mangling of the compiler. It is described as a linkage issue but that is not quite true - you will get errors from both the compiler and the linker.

The compiler errors will be if you try to use C++ features of prototype declaration such as overloading.

The linker errors will occur later because your function will appear to not be found, if you do not have the extern "C" wrapper around declarations and the header is included in a mixture of C and C++ source.

One reason to discourage people from using the compile C as C++ setting is because this means their source code is no longer portable. That setting is a project setting and so if a .c file is dropped into another project, it will not be compiled as c++. I would rather people take the time to rename file suffixes to .cpp.

The name of the DOM function is actually getElementsByClassName, not getElementByClassName, simply because more than one element on the page can have the same class, hence: Elements.

The return value of this will be a NodeList instance, or a superset of the NodeList (FF, for instance returns an instance of HTMLCollection). At any rate: the return value is an array-like object:

var y = document.getElementsByClassName('foo');
var aNode = y[0];

If, for some reason you need the return object as an array, you can do that easily, because of its magic length property:

var arrFromList = Array.prototype.slice.call(y);
//or as per AntonB's comment:
var arrFromList = [].slice.call(y);

As yckart suggested querySelector('.foo') and querySelectorAll('.foo') would be preferable, though, as they are, indeed, better supported (93.99% vs 87.24%), according to caniuse.com:

• querySelector(all)
• getElementsByClassName
• Don't use w3schools to learn something
• Refer to MDN for accurate information

Depending on distribution, using "cron reload" might do nothing. To paste a snippet out of init.d/cron (debian squeeze):

reload|force-reload) log_daemon_msg "Reloading configuration files for periodic command scheduler" "cron"
    # cron reloads automatically
    log_end_msg 0
    ;;

Some developer/maintainer relied on it reloading, but doesn't, and in this case there's not a way to force reload. I'm generating my crontab files as part of a deploy, and unless somehow the length of the file changes, the changes are not reloaded.

I would do something like the following:

INSERT INTO cache VALUES (key, generation)
ON DUPLICATE KEY UPDATE (key = key, generation = generation + 1);

Setting the generation value to 0 in code or in the sql but the using the ON DUP... to increment the value. I think that's the syntax anyway.
