I just made a JSFiddle that show pagination + search + order by on each column using Build with Twitter Bootstrap code: http://jsfiddle.net/SAWsA/11/

I faced same problem in emulator, but I solved it like this:

Create new emulator with x86_64 system image(ABI)

select device

select x86_64

That's it.

This error indicates the system(Device) not capable for run the application.

I hope this is helpful to someone.

You need to run the script as source or the shorthand .

source ./myscript.sh

or

. ./myscript.sh

This will run within the existing shell, ensuring any variables created or modified by the script will be available after the script completes.

Running the script just using the filename will execute the script in a separate subshell.

PermGen Space stands for memory allocation for Permanent generation All Java immutable objects come under this category, like String which is created with literals or with String.intern() methods and for loading the classes into memory. PermGen Space speeds up our String equality searching.

Many users have replied with os.walk answers, which includes all files but also all directories and subdirectories and their files.

import os


def files_in_dir(path, extension=''):
    """
       Generator: yields all of the files in <path> ending with
       <extension>

       \param   path       Absolute or relative path to inspect,
       \param   extension  [optional] Only yield files matching this,

       \yield              [filenames]
    """


    for _, dirs, files in os.walk(path):
        dirs[:] = []  # do not recurse directories.
        yield from [f for f in files if f.endswith(extension)]

# Example: print all the .py files in './python'
for filename in files_in_dir('./python', '*.py'):
    print("-", filename)

Or for a one off where you don't need a generator:

path, ext = "./python", ext = ".py"
for _, _, dirfiles in os.walk(path):
    matches = (f for f in dirfiles if f.endswith(ext))
    break

for filename in matches:
    print("-", filename)

If you are going to use matches for something else, you may want to make it a list rather than a generator expression:

    matches = [f for f in dirfiles if f.endswith(ext)]

Use p{width} column specifier: e.g. \begin{tabular}{ l p{10cm} } will put column's content into 10cm-wide parbox, and the text will be properly broken to several lines, like in normal paragraph.

You can also use tabular* environment to specify width for the entire table.

If you are using a reverse proxy such as nginx in between, you could define a custom token, such as X-API-Token.

In nginx you would rewrite it for the upstream proxy (your rest api) to be just auth:

proxy_set_header Authorization $http_x_api_token;

... while nginx can use the original Authorization header to check HTTP AUth.

** Update ** A scalars converter has been added to retrofit that allows for a String response with less ceremony than my original answer below.

Example interface --

public interface GitHubService {
    @GET("/users/{user}")
    Call<String> listRepos(@Path("user") String user);
}

Add the ScalarsConverterFactory to your retrofit builder. Note: If using ScalarsConverterFactory and another factory, add the scalars factory first.

Retrofit retrofit = new Retrofit.Builder()
    .baseUrl(BASE_URL)
    .addConverterFactory(ScalarsConverterFactory.create())
    // add other factories here, if needed.
    .build();

You will also need to include the scalars converter in your gradle file --

implementation 'com.squareup.retrofit2:converter-scalars:2.1.0'

--- Original Answer (still works, just more code) ---

I agree with @CommonsWare that it seems a bit odd that you want to intercept the request to process the JSON yourself. Most of the time the POJO has all the data you need, so no need to mess around in JSONObject land. I suspect your specific problem might be better solved using a custom gson TypeAdapter or a retrofit Converter if you need to manipulate the JSON. However, retrofit provides more the just JSON parsing via Gson. It also manages a lot of the other tedious tasks involved in REST requests. Just because you don't want to use one of the features, doesn't mean you have to throw the whole thing out. There are times you just want to get the raw stream, so here is how to do it -

First, if you are using Retrofit 2, you should start using the Call API. Instead of sending an object to convert as the type parameter, use ResponseBody from okhttp --

public interface GitHubService {
    @GET("/users/{user}")
    Call<ResponseBody> listRepos(@Path("user") String user);
}

then you can create and execute your call --

GitHubService service = retrofit.create(GitHubService.class);
Call<ResponseBody> result = service.listRepos(username);
result.enqueue(new Callback<ResponseBody>() {
    @Override
    public void onResponse(Response<ResponseBody> response) {
        try {
            System.out.println(response.body().string());
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

    @Override
    public void onFailure(Throwable t) {
        e.printStackTrace();
    }
});

Note The code above calls string() on the response object, which reads the entire response into a String. If you are passing the body off to something that can ingest streams, you can call charStream() instead. See the ResponseBody docs.

Yeah, I know, this is an ancient question, but I'll throw in my two cents:

LinkedList is almost always the wrong choice, performance-wise. There are some very specific algorithms where a LinkedList is called for, but those are very, very rare and the algorithm will usually specifically depend on LinkedList's ability to insert and delete elements in the middle of the list relatively quickly, once you've navigated there with a ListIterator.

There is one common use case in which LinkedList outperforms ArrayList: that of a queue. However, if your goal is performance, instead of LinkedList you should also consider using an ArrayBlockingQueue (if you can determine an upper bound on your queue size ahead of time, and can afford to allocate all the memory up front), or this CircularArrayList implementation. (Yes, it's from 2001, so you'll need to generify it, but I got comparable performance ratios to what's quoted in the article just now in a recent JVM)

You can also do this with ArgueJS:

function (){
  arguments = __({nodebox: undefined, str: [String: "hai"]})

  // and now on, you can access your arguments by
  //   arguments.nodebox and arguments.str
}

<b>request.META</b><br>
{% for k_meta, v_meta in request.META.items %}
  <code>{{ k_meta }}</code> : {{ v_meta }} <br>
{% endfor %}

The default value for client_max_body_size directive is 1 MiB.

It can be set in http, server and location context — as in the most cases, this directive in a nested block takes precedence over the same directive in the ancestors blocks.

Excerpt from the ngx_http_core_module documentation:

Syntax:   client_max_body_size size;
Default:  client_max_body_size 1m;
Context:  http, server, location

Sets the maximum allowed size of the client request body, specified in the “Content-Length” request header field. If the size in a request exceeds the configured value, the 413 (Request Entity Too Large) error is returned to the client. Please be aware that browsers cannot correctly display this error. Setting size to 0 disables checking of client request body size.

Don't forget to reload configuration by nginx -s reload or service nginx reload commands prepending with sudo (if any).

You need to save your PHP script file in UTF-8 encoding, and leave the <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> in the HTML.

For text editor, I recommend Notepad++, because it can detect and display the actual encoding of the file (in the lower right corner of the editor), and you can convert it as well.

The output of ps aux looks like you did not start docker through systemd/systemctl.

It looks like you started it with:

sudo dockerd -H gridsim1103:2376

When you try to stop it with systemctl, nothing should happen as the resulting dockerd process is not controlled by systemd. So the behavior you see is expected.

The correct way to start docker is to use systemd/systemctl:

systemctl enable docker
systemctl start docker

After this, docker should start on system start.

EDIT: As you already have the docker process running, simply kill it by pressing CTRL+C on the terminal you started it. Or send a kill signal to the process.

To prevent this, make sure every BEGIN TRANSACTION has COMMIT

The following will say successful but will leave uncommitted transactions:

BEGIN TRANSACTION
BEGIN TRANSACTION
<SQL_CODE?
COMMIT

Closing query windows with uncommitted transactions will prompt you to commit your transactions. This will generally resolve the Error 1222 message.

Actually i think that you have downloaded just a part of the script. Try to check 'Core' checkbox before download the whole script in jquery site.

Your image view will not show if you don't put that, don't ask me why.

You can do this in a slightly hack-y way by:

1. Stop Tomcat
2. Move ROOT.war aside and rm -rf webapps/ROOT
3. Copy the webapp you want to webapps/ROOT.war
4. Start Tomcat

A bit off on the "duck typing" definition -- dict.keys() returns an iterable object, not a list-like object. It will work anywhere an iterable will work -- not any place a list will. a list is also an iterable, but an iterable is NOT a list (or sequence...)

In real use-cases, the most common thing to do with the keys in a dict is to iterate through them, so this makes sense. And if you do need them as a list you can call list().

Very similarly for zip() -- in the vast majority of cases, it is iterated through -- why create an entire new list of tuples just to iterate through it and then throw it away again?

This is part of a large trend in python to use more iterators (and generators), rather than copies of lists all over the place.

dict.keys() should work with comprehensions, though -- check carefully for typos or something... it works fine for me:

>>> d = dict(zip(['Sounder V Depth, F', 'Vessel Latitude, Degrees-Minutes'], [None, None]))
>>> [key.split(", ") for key in d.keys()]
[['Sounder V Depth', 'F'], ['Vessel Latitude', 'Degrees-Minutes']]

A quick extension method:

    public static void IfNotNull<T>(this T obj, Action<T> action, Action actionIfNull = null) where T : class {
        if(obj != null) {
            action(obj);
        } else if ( actionIfNull != null ) {
            actionIfNull();
        }
    }

example:

  string str = null;
  str.IfNotNull(s => Console.Write(s.Length));
  str.IfNotNull(s => Console.Write(s.Length), () => Console.Write("null"));

or alternatively:

    public static TR IfNotNull<T, TR>(this T obj, Func<T, TR> func, Func<TR> ifNull = null) where T : class {
        return obj != null ? func(obj) : (ifNull != null ? ifNull() : default(TR));
    }

example:

    string str = null;
    Console.Write(str.IfNotNull(s => s.Length.ToString());
    Console.Write(str.IfNotNull(s => s.Length.ToString(), () =>  "null"));

I used a slightly modified version:

with open(file_name, 'w', encoding = 'utf-8') as f:
    for rec_index, rec in df.iterrows():
        f.write(rec['<field>'] + '\n')

I had to write the contents of a dataframe field (that was delimited) as a text file.

Modernizr is also a great option for giving IE HTML5 rendering capabilities.

tl;dr

LocalDate.parse( 
    "23/01/2017" ,  
    DateTimeFormatter.ofPattern( "dd/MM/uuuu" , Locale.UK ) 
).format(
    DateTimeFormatter.ofPattern( "uuuu/MM/dd" , Locale.UK )
)

Avoid legacy date-time classes

The answer by Christopher Parker is correct but outdated. The troublesome old date-time classes such as java.util.Date, java.util.Calendar, and java.text.SimpleTextFormat are now legacy, supplanted by the java.time classes.

Using java.time

Parse the input string as a date-time object, then generate a new String object in the desired format.

The LocalDate class represents a date-only value without time-of-day and without time zone.

DateTimeFormatter fIn = DateTimeFormatter.ofPattern( "dd/MM/uuuu" , Locale.UK );  // As a habit, specify the desired/expected locale, though in this case the locale is irrelevant.
LocalDate ld = LocalDate.parse( "23/01/2017" , fIn );

Define another formatter for the output.

DateTimeFormatter fOut = DateTimeFormatter.ofPattern( "uuuu/MM/dd" , Locale.UK );
String output = ld.format( fOut );

2017/01/23

By the way, consider using standard ISO 8601 formats for strings representing date-time values.

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

Where to obtain the java.time classes?

• Java SE 8, Java SE 9, and later
  • Built-in.
  • Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and Java SE 7
  • Much of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • The ThreeTenABP project adapts ThreeTen-Backport (mentioned above) for Android specifically.
  • See How to use ThreeTenABP….

The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval, YearWeek, YearQuarter, and more.

Joda-Time

UPDATE: The Joda-Time project is now in maintenance mode, with the team advising migration to the java.time classes. This section here is left for the sake of history.

For fun, here is his code adapted for using the Joda-Time library.

// © 2013 Basil Bourque. This source code may be used freely forever by anyone taking full responsibility for doing so.
// import org.joda.time.*;
// import org.joda.time.format.*;

final String OLD_FORMAT = "dd/MM/yyyy";
final String NEW_FORMAT = "yyyy/MM/dd";

// August 12, 2010
String oldDateString = "12/08/2010";
String newDateString;

DateTimeFormatter formatterOld = DateTimeFormat.forPattern(OLD_FORMAT);
DateTimeFormatter formatterNew = DateTimeFormat.forPattern(NEW_FORMAT);
LocalDate localDate = formatterOld.parseLocalDate( oldDateString );
newDateString = formatterNew.print( localDate );

Dump to console…

System.out.println( "localDate: " + localDate );
System.out.println( "newDateString: " + newDateString );

When run…

localDate: 2010-08-12
newDateString: 2010/08/12

If the problem is occurring on a device, check if traffic is going through a proxy (Settings > Wi-Fi > (info) > HTTP Proxy). I had my device setup to use with Charles, but forgot about the proxy. Seems that without Charles actually running this error occurs.

1. Check what security group you are using for your instance. See value of Security Groups column in row of your instance. It's important - I changed rules for default group, but my instance was under quickstart-1 group when I had similar issue.
2. Go to Security Groups tab, go to Inbound tab, select HTTP in Create a new rule combo-box, leave 0.0.0.0/0 in source field and click Add Rule, then Apply rule changes.

After hours of searching and looking for answer, finally I made it!!!!! Code is below :))))

HTML:

<form id="fileinfo" enctype="multipart/form-data" method="post" name="fileinfo">
    <label>File to stash:</label>
    <input type="file" name="file" required />
</form>
<input type="button" value="Stash the file!"></input>
<div id="output"></div>

jQuery:

$(function(){
    $('#uploadBTN').on('click', function(){ 
        var fd = new FormData($("#fileinfo"));
        //fd.append("CustomField", "This is some extra data");
        $.ajax({
            url: 'upload.php',  
            type: 'POST',
            data: fd,
            success:function(data){
                $('#output').html(data);
            },
            cache: false,
            contentType: false,
            processData: false
        });
    });
});

In the upload.php file you can access the data passed with $_FILES['file'].

Thanks everyone for trying to help:)

I took the answer from here (with some changes) MDN

Update your build.gradle(Module:app) add compileOptions block and add JavaVersion.VERSION_1_8

apply plugin: 'com.android.application'

android {
    .................
    .........................
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
}

I had the same problem... I had to run it as a user.

00 * * * * root /usr/bin/php /var/virtual/hostname.nz/public_html/cronjob.php

If you're using a self hosted site like me, the way to avoid this problem (as described above) is to stipulate on both the host and client side that the wsHttpBinding security mode = NONE.

When creating the binding, both on the client and the host, you can use this code:

 Dim binding as System.ServiceModel.WSHttpBinding 
 binding= New System.ServiceModel.WSHttpBinding(System.ServiceModel.SecurityMode.None)

or

 System.ServiceModel.WSHttpBinding binding
 binding = new System.ServiceModel.WSHttpBinding(System.ServiceModel.SecurityMode.None);

Make sure you type the command from the "App" Directory

you can get method parameter and its value and if annotated with a annotation with following code:

Map<String, Object> annotatedParameterValue = getAnnotatedParameterValue(MethodSignature.class.cast(jp.getSignature()).getMethod(), jp.getArgs()); ....

private Map<String, Object> getAnnotatedParameterValue(Method method, Object[] args) {
        Map<String, Object> annotatedParameters = new HashMap<>();
        Annotation[][] parameterAnnotations = method.getParameterAnnotations();
        Parameter[] parameters = method.getParameters();

        int i = 0;
        for (Annotation[] annotations : parameterAnnotations) {
            Object arg = args[i];
            String name = parameters[i++].getDeclaringExecutable().getName();
            for (Annotation annotation : annotations) {
                if (annotation instanceof AuditExpose) {
                    annotatedParameters.put(name, arg);
                }
            }
        }
        return annotatedParameters;
    }

MacVim is just Vim. Anything you are used to do in Vim will work exactly the same way in MacVim.

MacVim is more integrated in the whole OS than Vim in the Terminal or even GVim in Linux, it follows a lot of Mac OS X's conventions.

If you work mainly with GUI apps (YummyFTP + GitX + Charles, for example) you may prefer MacVim.

If you work mainly with CLI apps (ssh + svn + tcpdump, for example) you may prefer vim in the terminal.

Entering and leaving one realm (CLI) for the other (GUI) and vice-versa can be "expensive".

I use both MacVim and Vim depending on the task and the context: if I'm in CLI-land I'll just type vim filename and if I'm in GUI-land I'll just invoke Quicksilver and launch MacVim.

When I switched from TextMate I kind of liked the fact that MacVim supported almost all of the regular shortcuts Mac users are accustomed to. I added some of my own, mimiking TextMate but, since I was working in multiple environments I forced my self to learn the vim way. Now I use both MacVim and Vim almost exactly the same way. Using one or the other is just a question of context for me.

Also, like El Isra said, the default vim (CLI) in OS X is slightly outdated. You may install an up-to-date version via MacPorts or you can install MacVim and add an alias to your .profile:

alias vim='/path/to/MacVim.app/Contents/MacOS/Vim'

to have the same vim in MacVim and Terminal.app.

Another difference is that many great colorschemes out there work out of the box in MacVim but look terrible in the Terminal.app which only supports 8 colors (+ highlights) but you can use iTerm — which can be set up to support 256 colors — instead of Terminal.

So… basically my advice is to just use both.

EDIT: I didn't try it but the latest version of Terminal.app (in 10.7) is supposed to support 256 colors. I'm still on 10.6.x at work so I'll still use iTerm2 for a while.

EDIT: An even better way to use MacVim's CLI executable in your shell is to move the mvim script bundled with MacVim somewhere in your $PATH and use this command:

$ mvim -v

EDIT: Yes, Terminal.app now supports 256 colors. So if you don't need iTerm2's advanced features you can safely use the default terminal emulator.

In my case, it is taking time in AM and PM but sending data in 00-24 hours format to the server on form submit. and when use that DB data in its value then it will automatically select the appropriate AM or PM to edit form value.

A solution written in pure Bash:

#!/bin/bash

sometext="something1:    +12.0   (some unnecessary trailing data (this must go))
something2:    +15.5   (some more unnecessary trailing data)
something4:    +9.0   (some other unnecessary data)
something1:    +13.5  (blah blah blah)"

a=()
while read -r a1 a2 a3; do
    # we can add some code here to check valid values or modify them
    a+=("${a2}")
done <<< "${sometext}"
# between parenthesis to modify IFS for the current statement only
(IFS=',' ; printf '%s: %s\n' "Result" "${a[*]}")

Result: +12.0,+15.5,+9.0,+13.5

            var lines = new List<string>();

            string[] columnNames = dt.Columns.Cast<DataColumn>().
                                              Select(column => column.ColumnName).
                                              ToArray();

            var header = string.Join(",", columnNames);
            lines.Add(header);
            var valueLines = dt.AsEnumerable()
                               .Select(row => string.Join(",", row.ItemArray));
            lines.AddRange(valueLines);
            File.WriteAllLines("excel.csv", lines);

Here dt refers to your DataTable pass as a paramter

I am going to blow everyone's mind right now . . .

Delete all the <assemblyBinding> references from your .config file, and then run this command from the NuGet Package Manager console:

Get-Project -All | Add-BindingRedirect

If maven is not creating Local Repository i.e .m2/repository folder then try below step.

In your Eclipse\Spring Tool Suite, Go to Window->preferences-> maven->user settings-> click on Restore Defaults-> Apply->Apply and close

You're mixing the parts together instead of separating them cleanly.

printf '\e[1;34m%-6s\e[m' "This is text"

Basically, put the fixed stuff in the format and the variable stuff in the parameters.

for my case this worked

str_to_date(date, '%e/%m/%Y' )

The above solutions like run a query

SET session wait_timeout=600;

Will only work until mysql is restarted. For a persistant solution, edit mysql.conf and add after [mysqld]:

wait_timeout=300
interactive_timeout = 300

Where 300 is the number of seconds you want.

IF NOT EXISTS(select * FROM sys.views where name = 'data_VVVV ')
    BEGIN

    END
ELSE

I tried many of these answers, but on my AIX system with gnu make 3.80 I needed to do some things old school.

Turns out that lastword, abspath and realpath were not added until 3.81. :(

mkfile_path := $(word $(words $(MAKEFILE_LIST)),$(MAKEFILE_LIST))
mkfile_dir:=$(shell cd $(shell dirname $(mkfile_path)); pwd)
current_dir:=$(notdir $(mkfile_dir))

As others have said, not the most elegant as it invokes a shell twice, and it still has the spaces issues.

But as I don't have any spaces in my paths, it works for me regardless of how I started make:

• make -f ../wherever/makefile
• make -C ../wherever
• make -C ~/wherever
• cd ../wherever; make

All give me wherever for current_dir and the absolute path to wherever for mkfile_dir.

If you are the only the person working on the project, what you can do is:

 git checkout master
 git push origin +HEAD

This will set the tip of origin/master to the same commit as master (and so delete the commits between 41651df and origin/master)

Besides using one of the default formats you can specify any size you want in the unit you specify.

For example:

// Document of 210mm wide and 297mm high
new jsPDF('p', 'mm', [297, 210]);
// Document of 297mm wide and 210mm high
new jsPDF('l', 'mm', [297, 210]);
// Document of 5 inch width and 3 inch high
new jsPDF('l', 'in', [3, 5]);

The 3rd parameter of the constructor can take an array of the dimensions. However they do not correspond to width and height, instead they are long side and short side (or flipped around).

Your 1st parameter (landscape or portrait) determines what becomes the width and the height.

In the sourcecode on GitHub you can see the supported units (relative proportions to pt), and you can also see the default page formats (with their sizes in pt).

When your are three tables or more, just add union and left outer join:

select a.col1, b.col2, a.col3, b.col4, a.category_id 
from 
(
    select category_id from a
    union
    select category_id from b
) as c
left outer join a on a.category_id = c.category_id
left outer join b on b.category_id = c.category_id

ko.applyBindings accepts a second parameter that is a DOM element to use as the root.

This would let you do something like:

<div id="one">
  <input data-bind="value: name" />
</div>

<div id="two">
  <input data-bind="value: name" />
</div>

<script type="text/javascript">
  var viewModelA = {
     name: ko.observable("Bob")
  };

  var viewModelB = {
     name: ko.observable("Ted")
  };

  ko.applyBindings(viewModelA, document.getElementById("one"));
  ko.applyBindings(viewModelB, document.getElementById("two"));
</script>

So, you can use this technique to bind a viewModel to the dynamic content that you load into your dialog. Overall, you just want to be careful not to call applyBindings multiple times on the same elements, as you will get multiple event handlers attached.

You can use anonymous types for this, i.e.:

var pageObject = (from op in db.ObjectPermissions
                  join pg in db.Pages on op.ObjectPermissionName equals page.PageName
                  where pg.PageID == page.PageID
                  select new { pg, op }).SingleOrDefault();

This will make pageObject into an IEnumerable of an anonymous type so AFAIK you won't be able to pass it around to other methods, however if you're simply obtaining data to play with in the method you're currently in it's perfectly fine. You can also name properties in your anonymous type, i.e.:-

var pageObject = (from op in db.ObjectPermissions
                  join pg in db.Pages on op.ObjectPermissionName equals page.PageName
                  where pg.PageID == page.PageID
                  select new
                  {
                      PermissionName = pg, 
                      ObjectPermission = op
                  }).SingleOrDefault();

This will enable you to say:-

if (pageObject.PermissionName.FooBar == "golden goose") Application.Exit();

For example :-)

I don't think one syntax has real value over another. It all boils down, like you mentionned, to uniformity across the source files.

The only point where I find such rules interesting is when I need 2 things named identicaly, for example :

void myFunc(int index){
  this->index = index;
}

void myFunc(int index){
  m_index = index;
}

I use it to differentiate the two. Also when I wrap calls, like from windows Dll, RecvPacket(...) from the Dll might be wrapped in RecvPacket(...) in my code. In these particular occasions using a prefix like "_" might make the two look alike, easy to identify which is which, but different for the compiler

Yes, it is valid.

As for making it work with functors as well, the usual solution is something like this instead:

template <typename F>
void doOperation(F f)
{
  int temp=0;
  f(temp);
  std::cout << "Result is " << temp << std::endl;
}

which can now be called as either:

doOperation(add2);
doOperation(add3());

See it live

The problem with this is that if it makes it tricky for the compiler to inline the call to add2, since all the compiler knows is that a function pointer type void (*)(int &) is being passed to doOperation. (But add3, being a functor, can be inlined easily. Here, the compiler knows that an object of type add3 is passed to the function, which means that the function to call is add3::operator(), and not just some unknown function pointer.)

You should also look at new triggers.

MySQL doesn't show the table name in the error, so you're really left in a lurch. Here's a working example:

use test;
create table blah (id int primary key AUTO_INCREMENT, data varchar(100));
create table audit_blah (audit_id int primary key AUTO_INCREMENT, action enum('INSERT','UPDATE','DELETE'), id int, data varchar(100) null);
insert into audit_blah(action, id, data) values ('INSERT', 1, 'a');
select * from blah;
select * from audit_blah;
truncate table audit_blah;

delimiter //
/* I've commented out "id" below, so the insert fails with an ambiguous error: */
create trigger ai_blah after insert on blah for each row 
begin 
  insert into audit_blah (action, /*id,*/ data) values ('INSERT', /*NEW.id,*/ NEW.data);
end;//

/* This insert is valid, but you'll get an exception from the trigger: */
insert into blah (data) values ('data1');

SELECT  [ReportId], 
        SUBSTRING(d.EmailList,1, LEN(d.EmailList) - 1) EmailList
FROM
        (
            SELECT DISTINCT [ReportId]
            FROM Table1
        ) a
        CROSS APPLY
        (
            SELECT [Email] + ', ' 
            FROM Table1 AS B 
            WHERE A.[ReportId] = B.[ReportId]
            FOR XML PATH('')
        ) D (EmailList) 

SQLFiddle Demo

NOTE: This answer is for SQL Server 2005. For SQL Server 2008 and later, there are much better methods as seen in the other answers.

You can use INSERT with SELECT UNION ALL:

INSERT INTO MyTable  (FirstCol, SecondCol)
    SELECT  'First' ,1
    UNION ALL
SELECT  'Second' ,2
    UNION ALL
SELECT  'Third' ,3
...

Only for small datasets though, which should be fine for your 4 records.

If you do not want to use regular expressions, and do not wish to rely on a third party library, you can use this method instead, which takes between 89920 and 100113 nanoseconds in a 2.80 GHz CPU (less than a millisecond). It's not as pretty as Simon Nickerson's example, but it works:

This error can happen when you are accessing the SSH URL (Read/Write) instead of Git Read-Only URL but you have no write access to that repo.

Sometimes you just want to clone your own repo, e.g. deploy to a server. In this case you actually only need READ-ONLY access. But since that's your own repo, GitHub may display SSH URL if that's your preference. In this situation, if your remote host's public key is not in your GitHub SSH Keys, your access will be denied, which is expected to happen.

An equivalent case is when you try cloning someone else's repo to which you have no write access with SSH URL.

In a word, if your intent is to clone-only a repo, use HTTPS URL (https://github.com/{user_name}/{project_name}.git) instead of SSH URL ([email protected]:{user_name}/{project_name}.git), which avoids (unnecessary) public key validation.

Update: GitHub is displaying HTTPS as the default protocol now and this move can probably reduce possible misuse of SSH URLs.

You can discover those things easily by yourself:

def hello(*args, **kwargs):
    print kwargs
    print type(kwargs)
    print dir(kwargs)

hello(what="world")

The easiest way is:

var oldstr="Angular isn't easy";
var newstr=oldstr.toString().replace("isn't","is");

You can use SHOW:

SHOW max_connections;

This returns the currently effective setting. Be aware that it can differ from the setting in postgresql.conf as there are a multiple ways to set run-time parameters in PostgreSQL. To reset the "original" setting from postgresql.conf in your current session:

RESET max_connections;

However, not applicable to this particular setting. The manual:

This parameter can only be set at server start.

To see all settings:

SHOW ALL;

There is also pg_settings:

The view pg_settings provides access to run-time parameters of the server. It is essentially an alternative interface to the SHOW and SET commands. It also provides access to some facts about each parameter that are not directly available from SHOW, such as minimum and maximum values.

For your original request:

SELECT *
FROM   pg_settings
WHERE  name = 'max_connections';

Finally, there is current_setting(), which can be nested in DML statements:

SELECT current_setting('max_connections');

It is important to clearly differentiate the idea behind using factory or factory method. Both are meant to address mutually exclusive different kind of object creation problems.

Let's be specific about "factory method":

First thing is that, when you are developing library or APIs which in turn will be used for further application development, then factory method is one of the best selections for creation pattern. Reason behind; We know that when to create an object of required functionality(s) but type of object will remain undecided or it will be decided ob dynamic parameters being passed.

Now the point is, approximately same can be achieved by using factory pattern itself but one huge drawback will introduce into the system if factory pattern will be used for above highlighted problem, it is that your logic of crating different objects(sub classes objects) will be specific to some business condition so in future when you need to extend your library's functionality for other platforms(In more technically, you need to add more sub classes of basic interface or abstract class so factory will return those objects also in addition to existing one based on some dynamic parameters) then every time you need to change(extend) the logic of factory class which will be costly operation and not good from design perspective. On the other side, if "factory method" pattern will be used to perform the same thing then you just need to create additional functionality(sub classes) and get it registered dynamically by injection which doesn't require changes in your base code.

File one:

angular.module('myApp.controllers', []);

File two:

angular.module('myApp.controllers').controller('Ctrl1', ['$scope', '$http', function($scope, $http){

}]);

File three:

angular.module('myApp.controllers').controller('Ctrl2', ['$scope', '$http', function($scope, $http){

}]);

Include in that order. I recommend 3 files so the module declaration is on its own.

As for folder structure there are many many many opinions on the subject, but these two are pretty good

If your modulus / divisor is a known constant, and you care about performance, see this and this. A multiplicative inverse is even possible for loop-invariant values that aren't known until runtime, e.g. see https://libdivide.com/ (But without JIT code-gen, that's less efficient than hard-coding just the steps necessary for one constant.)

Never use div for known powers of 2: it's much slower than and for remainder, or right-shift for divide. Look at C compiler output for examples of unsigned or signed division by powers of 2, e.g. on the Godbolt compiler explorer. If you know a runtime input is a power of 2, use lea eax, [esi-1] ; and eax, edi or something like that to do x & (y-1). Modulo 256 is even more efficient: movzx eax, cl has zero latency on recent Intel CPUs (mov-elimination), as long as the two registers are separate.

In the simple/general case: unknown value at runtime

The DIV instruction (and its counterpart IDIV for signed numbers) gives both the quotient and remainder. For unsigned, remainder and modulus are the same thing. For signed idiv, it gives you the remainder (not modulus) which can be negative:
e.g. -5 / 2 = -2 rem -1. x86 division semantics exactly match C99's % operator.

DIV r32 divides a 64-bit number in EDX:EAX by a 32-bit operand (in any register or memory) and stores the quotient in EAX and the remainder in EDX. It faults on overflow of the quotient.

Unsigned 32-bit example (works in any mode)

mov eax, 1234          ; dividend low half
mov edx, 0             ; dividend high half = 0.  prefer  xor edx,edx

mov ebx, 10            ; divisor can be any register or memory

div ebx       ; Divides 1234 by 10.
        ; EDX =   4 = 1234 % 10  remainder
        ; EAX = 123 = 1234 / 10  quotient

In 16-bit assembly you can do div bx to divide a 32-bit operand in DX:AX by BX. See Intel's Architectures Software Developer’s Manuals for more information.

Normally always use xor edx,edx before unsigned div to zero-extend EAX into EDX:EAX. This is how you do "normal" 32-bit / 32-bit => 32-bit division.

For signed division, use cdq before idiv to sign-extend EAX into EDX:EAX. See also Why should EDX be 0 before using the DIV instruction?. For other operand-sizes, use cbw (AL->AX), cwd (AX->DX:AX), cdq (EAX->EDX:EAX), or cqo (RAX->RDX:RAX) to set the top half to 0 or -1 according to the sign bit of the low half.

div / idiv are available in operand-sizes of 8, 16, 32, and (in 64-bit mode) 64-bit. 64-bit operand-size is much slower than 32-bit or smaller on current Intel CPUs, but AMD CPUs only care about the actual magnitude of the numbers, regardless of operand-size.

Note that 8-bit operand-size is special: the implicit inputs/outputs are in AH:AL (aka AX), not DL:AL. See 8086 assembly on DOSBox: Bug with idiv instruction? for an example.

Signed 64-bit division example (requires 64-bit mode)

   mov    rax,  0x8000000000000000   ; INT64_MIN = -9223372036854775808
   mov    ecx,  10           ; implicit zero-extension is fine for positive numbers

   cqo                       ; sign-extend into RDX, in this case = -1 = 0xFF...FF
   idiv   rcx
       ; quotient  = RAX = -922337203685477580 = 0xf333333333333334
       ; remainder = RDX = -8                  = 0xfffffffffffffff8

Limitations / common mistakes

div dword 10 is not encodeable into machine code (so your assembler will report an error about invalid operands).

Unlike with mul/imul (where you should normally use faster 2-operand imul r32, r/m32 or 3-operand imul r32, r/m32, imm8/32 instead that don't waste time writing a high-half result), there is no newer opcode for division by an immediate, or 32-bit/32-bit => 32-bit division or remainder without the high-half dividend input.

Division is so slow and (hopefully) rare that they didn't bother to add a way to let you avoid EAX and EDX, or to use an immediate directly.

div and idiv will fault if the quotient doesn't fit into one register (AL / AX / EAX / RAX, the same width as the dividend). This includes division by zero, but will also happen with a non-zero EDX and a smaller divisor. This is why C compilers just zero-extend or sign-extend instead of splitting up a 32-bit value into DX:AX.

And also why INT_MIN / -1 is C undefined behaviour: it overflows the signed quotient on 2's complement systems like x86. See Why does integer division by -1 (negative one) result in FPE? for an example of x86 vs. ARM. x86 idiv does indeed fault in this case.

The x86 exception is #DE - divide exception. On Unix/Linux systems, the kernel delivers a SIGFPE arithmetic exception signal to processes that cause a #DE exception. (On which platforms does integer divide by zero trigger a floating point exception?)

For div, using a dividend with high_half < divisor is safe. e.g. 0x11:23 / 0x12 is less than 0xff so it fits in an 8-bit quotient.

Extended-precision division of a huge number by a small number can be implemented by using the remainder from one chunk as the high-half dividend (EDX) for the next chunk. This is probably why they chose remainder=EDX quotient=EAX instead of the other way around.

TL;DR

SELECT json_agg(t) FROM t

for a JSON array of objects, and

SELECT
    json_build_object(
        'a', json_agg(t.a),
        'b', json_agg(t.b)
    )
FROM t

for a JSON object of arrays.

List of objects

This section describes how to generate a JSON array of objects, with each row being converted to a single object. The result looks like this:

[{"a":1,"b":"value1"},{"a":2,"b":"value2"},{"a":3,"b":"value3"}]

9.3 and up

The json_agg function produces this result out of the box. It automatically figures out how to convert its input into JSON and aggregates it into an array.

SELECT json_agg(t) FROM t

There is no jsonb (introduced in 9.4) version of json_agg. You can either aggregate the rows into an array and then convert them:

SELECT to_jsonb(array_agg(t)) FROM t

or combine json_agg with a cast:

SELECT json_agg(t)::jsonb FROM t

My testing suggests that aggregating them into an array first is a little faster. I suspect that this is because the cast has to parse the entire JSON result.

9.2

9.2 does not have the json_agg or to_json functions, so you need to use the older array_to_json:

SELECT array_to_json(array_agg(t)) FROM t

You can optionally include a row_to_json call in the query:

SELECT array_to_json(array_agg(row_to_json(t))) FROM t

This converts each row to a JSON object, aggregates the JSON objects as an array, and then converts the array to a JSON array.

I wasn't able to discern any significant performance difference between the two.

Object of lists

This section describes how to generate a JSON object, with each key being a column in the table and each value being an array of the values of the column. It's the result that looks like this:

{"a":[1,2,3], "b":["value1","value2","value3"]}

9.5 and up

We can leverage the json_build_object function:

SELECT
    json_build_object(
        'a', json_agg(t.a),
        'b', json_agg(t.b)
    )
FROM t

You can also aggregate the columns, creating a single row, and then convert that into an object:

SELECT to_json(r)
FROM (
    SELECT
        json_agg(t.a) AS a,
        json_agg(t.b) AS b
    FROM t
) r

Note that aliasing the arrays is absolutely required to ensure that the object has the desired names.

Which one is clearer is a matter of opinion. If using the json_build_object function, I highly recommend putting one key/value pair on a line to improve readability.

You could also use array_agg in place of json_agg, but my testing indicates that json_agg is slightly faster.

There is no jsonb version of the json_build_object function. You can aggregate into a single row and convert:

SELECT to_jsonb(r)
FROM (
    SELECT
        array_agg(t.a) AS a,
        array_agg(t.b) AS b
    FROM t
) r

Unlike the other queries for this kind of result, array_agg seems to be a little faster when using to_jsonb. I suspect this is due to overhead parsing and validating the JSON result of json_agg.

Or you can use an explicit cast:

SELECT
    json_build_object(
        'a', json_agg(t.a),
        'b', json_agg(t.b)
    )::jsonb
FROM t

The to_jsonb version allows you to avoid the cast and is faster, according to my testing; again, I suspect this is due to overhead of parsing and validating the result.

9.4 and 9.3

The json_build_object function was new to 9.5, so you have to aggregate and convert to an object in previous versions:

SELECT to_json(r)
FROM (
    SELECT
        json_agg(t.a) AS a,
        json_agg(t.b) AS b
    FROM t
) r

or

SELECT to_jsonb(r)
FROM (
    SELECT
        array_agg(t.a) AS a,
        array_agg(t.b) AS b
    FROM t
) r

depending on whether you want json or jsonb.

(9.3 does not have jsonb.)

9.2

In 9.2, not even to_json exists. You must use row_to_json:

SELECT row_to_json(r)
FROM (
    SELECT
        array_agg(t.a) AS a,
        array_agg(t.b) AS b
    FROM t
) r

Documentation

Find the documentation for the JSON functions in JSON functions.

json_agg is on the aggregate functions page.

Design

If performance is important, ensure you benchmark your queries against your own schema and data, rather than trust my testing.

Whether it's a good design or not really depends on your specific application. In terms of maintainability, I don't see any particular problem. It simplifies your app code and means there's less to maintain in that portion of the app. If PG can give you exactly the result you need out of the box, the only reason I can think of to not use it would be performance considerations. Don't reinvent the wheel and all.

Nulls

Aggregate functions typically give back NULL when they operate over zero rows. If this is a possibility, you might want to use COALESCE to avoid them. A couple of examples:

SELECT COALESCE(json_agg(t), '[]'::json) FROM t

Or

SELECT to_jsonb(COALESCE(array_agg(t), ARRAY[]::t[])) FROM t

The other important reason sessions can not work is playing with the session cookie settings, eg. setting session cookie lifetime to 0 or other low values because of simple mistake or by other developer for a reason.

$update_query = "UPDATE db.tablename SET insert_time=".$date." WHERE username='" .$somename . "'"; 

These two style of filtering are equivalent in most cases, but when query on objects base on ForeignKey or ManyToManyField, they are slightly different.

Examples from the documentation.

model
Blog to Entry is a one-to-many relation.

from django.db import models

class Blog(models.Model):
    ...

class Entry(models.Model):
    blog = models.ForeignKey(Blog)
    headline = models.CharField(max_length=255)
    pub_date = models.DateField()
    ...

objects
Assuming there are some blog and entry objects here.

queries

Blog.objects.filter(entry__headline_contains='Lennon', 
    entry__pub_date__year=2008)
Blog.objects.filter(entry__headline_contains='Lennon').filter(
    entry__pub_date__year=2008)  
    

For the 1st query (single filter one), it match only blog1.

For the 2nd query (chained filters one), it filters out blog1 and blog2.
The first filter restricts the queryset to blog1, blog2 and blog5; the second filter restricts the set of blogs further to blog1 and blog2.

And you should realize that

We are filtering the Blog items with each filter statement, not the Entry items.

So, it's not the same, because Blog and Entry are multi-valued relationships.

It might be that the package "Combinations" is not updated anymore and does not work with a recent version of R (I was also unable to install it on R 2.13.1 on windows). The package "combinat" installs without problem for me and might be a solution for you depending on what exactly you're trying to do.

try following solution

HTML:

<div id="variant">
<label><input type="radio" name="toggle" class="radio" value="19,99€"><span>A</span></label>
<label><input type="radio" name="toggle" class="radio" value="<<<"><span>B</span></label>
<label><input type="radio" name="toggle" class="radio" value="xxx"><span>C</span></label>
<p id="price"></p>

JS:

$(document).ready(function () {
       $('.radio').click(function () {
           document.getElementById('price').innerHTML = $(this).val();
       });

   });

Put this line at the top of your source

# -*- coding: utf-8 -*-

If your editor uses a different encoding, substitute for utf-8

Then you can include utf-8 characters directly in the source

Try with the following code to get width and height of screen

int widthOfscreen =0;
int heightOfScreen = 0;
DisplayMetrics dm = new DisplayMetrics();
        try {
            ((Activity) context).getWindowManager().getDefaultDisplay()
                    .getMetrics(dm);
        } catch (Exception ex) {
        }
         widthOfscreen  = dm.widthPixels;
heightOfScreen  = dm.heightPixels;

Use CSS:

<input type="text" class="bigText"  name=" item" align="left" />

.bigText {
    height:30px;
}

Dreamweaver is a poor testing tool. It is not a browser.

I also had the same problem some time before, but I solved that issue.

There may be different reasons for this exception. And one of them may be that the jar you are adding to your lib folder may be old.

Try to find out the latest mysql-connector-jar version and add that to your classpath. It may solve your issue. Mine was solved like that.

$query = "ALTER TABLE `" . $table_prefix . "posts_to_bookmark` 
          ADD COLUMN `ping_status` INT(1) NOT NULL 
          AFTER `<TABLE COLUMN BEFORE THIS COLUMN>`";

I believe you need to have ADD COLUMN and use AFTER, not BEFORE.

In case you want to place column at the beginning of a table, use the FIRST statement:

$query = "ALTER TABLE `" . $table_prefix . "posts_to_bookmark`
          ADD COLUMN `ping_status` INT(1) NOT NULL 
          FIRST";

http://dev.mysql.com/doc/refman/5.1/en/alter-table.html

You could just use a simple JavaScript regular expression to test for purely numeric characters:

/^[0-9]+$/.test(input);

This returns true if the input is numeric or false if not.

or for event keycode, simple use below :

     // Allow: backspace, delete, tab, escape, enter, ctrl+A and .
    if ($.inArray(e.keyCode, [46, 8, 9, 27, 13, 110, 190]) !== -1 ||
         // Allow: Ctrl+A
        (e.keyCode == 65 && e.ctrlKey === true) || 
         // Allow: home, end, left, right
        (e.keyCode >= 35 && e.keyCode <= 39)) {
             // let it happen, don't do anything
             return;
    }

    var charValue = String.fromCharCode(e.keyCode)
        , valid = /^[0-9]+$/.test(charValue);

    if (!valid) {
        e.preventDefault();
    }

You can try export http_proxy=http://your_proxy:your_port

public class DummyViewModel : ViewModelBase
    {
        private bool isfocused= false;
        public bool IsFocused
        {
            get
            {
                return isfocused;
            }
            set
            {
                isfocused= value;
                OnPropertyChanged("IsFocused");
            }
        }
    }

Simply add

this.WindowState = FormWindowState.Minimized;
this.ShowInTaskbar = false;

to your form object. You will see only an icon at system tray.

NGINX large uploads are successfully working on hosted WordPress sites, finally (as per suggestions from nembleton & rjha94)

I thought it might be helpful for someone, if I added a little clarification to their suggestions. For starters, please be certain you have included your increased upload directive in ALL THREE separate definition blocks (server, location & http). Each should have a separate line entry. The result will like something like this (where the ... reflects other lines in the definition block):

http {
    ...
    client_max_body_size 200M;
}    

(in my ISPconfig 3 setup, this block is in the /etc/nginx/nginx.conf file)

server {
    ...
    client_max_body_size 200M;
}

location / {
    ...
    client_max_body_size 200M;
} 

(in my ISPconfig 3 setup, these blocks are in the /etc/nginx/conf.d/default.conf file)

Also, make certain that your server's php.ini file is consistent with these NGINX settings. In my case, I changed the setting in php.ini's File_Uploads section to read:

upload_max_filesize = 200M

Note: if you are managing an ISPconfig 3 setup (my setup is on CentOS 6.3, as per The Perfect Server), you will need to manage these entries in several separate files. If your configuration is similar to one in the step-by-step setup, the NGINX conf files you need to modify are located here:

/etc/nginx/nginx.conf
/etc/nginx/conf.d/default.conf 

My php.ini file was located here:

/etc/php.ini

I continued to overlook the http {} block in the nginx.conf file. Apparently, overlooking this had the effect of limiting uploading to the 1M default limit. After making the associated changes, you will also want to be sure to restart your NGINX and PHP FastCGI Process Manager (PHP-FPM) services. On the above configuration, I use the following commands:

/etc/init.d/nginx restart
/etc/init.d/php-fpm restart

By putting an assignment of list on a variable first

myVar <- list()

it opens the possibility of hiearchial assignments by

myVar[[1]] <- list()
myVar[[2]] <- list()

and so on... so now it's possible to do

myVar[[1]][[1]] <- c(...)
myVar[[1]][[2]] <- c(...)

or

myVar[[1]][['subVar']] <- c(...)

and so on

it is also possible to assign directly names (instead of $)

myVar[['nameofsubvar]] <- list()

and then

myVar[['nameofsubvar]][['nameofsubsubvar']] <- c('...')

important to remember is to always use double brackets to make the system work

then to get information is simple

myVar$nameofsubvar$nameofsubsubvar

and so on...

example:

a <-list()
a[['test']] <-list()
a[['test']][['subtest']] <- c(1,2,3)
a
$test
$test$subtest
[1] 1 2 3


a[['test']][['sub2test']] <- c(3,4,5)
a
$test
$test$subtest
[1] 1 2 3

$test$sub2test
[1] 3 4 5

a nice feature of the R language in it's hiearchial definition...

I used it for a complex implementation (with more than two levels) and it works!

As said by jensgram, IE6 does not support attribute selector. You could add a class="disabled" to select the disabled inputs so that this can work in IE6.

Another alternative would be to set environment variable ANDROID_SERIAL to the relevant serial, here assuming you are using Windows:

set ANDROID_SERIAL=7f1c864e
echo %ANDROID_SERIAL%
"7f1c864e"

Then you can use adb.exe shell without any issues.

Thanks All for your responses. Good solution was to use 'brain`s' method:

List<Object> list = getHouseInfo();
for (int i=0; i<list.size; i++){
Object[] row = (Object[]) list.get(i);
System.out.println("Element "+i+Arrays.toString(row));
}

Problem solved. Thanks again.

UPDATE: (5 years later)

Note: If you decide to use Kappa Architecture (Event Sourcing + CQRS), then you do not need updated date at all. Since your data is an immutable, append-only event log, you only ever need event created date. Similar to the Lambda Architecture, described below. Then your application state is a projection of the event log (derived data). If you receive a subsequent event about existing entity, then you'll use that event's created date as updated date for your entity. This is a commonly used (and commonly misunderstood) practice in miceroservice systems.

UPDATE: (4 years later)

If you use ObjectId as your _id field (which is usually the case), then all you need to do is:

let document = {
  updatedAt: new Date(),
}

Check my original answer below on how to get the created timestamp from the _id field. If you need to use IDs from external system, then check Roman Rhrn Nesterov's answer.

UPDATE: (2.5 years later)

You can now use the #timestamps option with mongoose version >= 4.0.

let ItemSchema = new Schema({
  name: { type: String, required: true, trim: true }
},
{
  timestamps: true
});

If set timestamps, mongoose assigns createdAt and updatedAt fields to your schema, the type assigned is Date.

You can also specify the timestamp fileds' names:

timestamps: { createdAt: 'created_at', updatedAt: 'updated_at' }

Note: If you are working on a big application with critical data you should reconsider updating your documents. I would advise you to work with immutable, append-only data (lambda architecture). What this means is that you only ever allow inserts. Updates and deletes should not be allowed! If you would like to "delete" a record, you could easily insert a new version of the document with some timestamp/version filed and then set a deleted field to true. Similarly if you want to update a document – you create a new one with the appropriate fields updated and the rest of the fields copied over.Then in order to query this document you would get the one with the newest timestamp or the highest version which is not "deleted" (the deleted field is undefined or false`).

Data immutability ensures that your data is debuggable – you can trace the history of every document. You can also rollback to previous version of a document if something goes wrong. If you go with such an architecture ObjectId.getTimestamp() is all you need, and it is not Mongoose dependent.

ORIGINAL ANSWER:

If you are using ObjectId as your identity field you don't need created_at field. ObjectIds have a method called getTimestamp().

ObjectId("507c7f79bcf86cd7994f6c0e").getTimestamp()

This will return the following output:

ISODate("2012-10-15T21:26:17Z")

More info here How do I extract the created date out of a Mongo ObjectID

In order to add updated_at filed you need to use this:

var ArticleSchema = new Schema({
  updated_at: { type: Date }
  // rest of the fields go here
});

ArticleSchema.pre('save', function(next) {
  this.updated_at = Date.now();
  next();
});

As the Python documentation says:

sys.maxsize

The largest positive integer supported by the platform’s Py_ssize_t type, and thus the maximum size lists, strings, dicts, and many other containers can have.

In my computer (Linux x86_64):

>>> import sys
>>> print sys.maxsize
9223372036854775807

I am not very sure whether it will make any difference in performance of my API.

Bear in mind that the primary benefit of asynchronous code on the server side is scalability. It won't magically make your requests run faster. I cover several "should I use async" considerations in my article on async ASP.NET.

I think your use case (calling other APIs) is well-suited for asynchronous code, just bear in mind that "asynchronous" does not mean "faster". The best approach is to first make your UI responsive and asynchronous; this will make your app feel faster even if it's slightly slower.

As far as the code goes, this is not asynchronous:

public Task<BackOfficeResponse<List<Country>>> ReturnAllCountries()
{
  var response = _service.Process<List<Country>>(BackOfficeEndpoint.CountryEndpoint, "returnCountries");
  return Task.FromResult(response);
}

You'd need a truly asynchronous implementation to get the scalability benefits of async:

public async Task<BackOfficeResponse<List<Country>>> ReturnAllCountriesAsync()
{
  return await _service.ProcessAsync<List<Country>>(BackOfficeEndpoint.CountryEndpoint, "returnCountries");
}

Or (if your logic in this method really is just a pass-through):

public Task<BackOfficeResponse<List<Country>>> ReturnAllCountriesAsync()
{
  return _service.ProcessAsync<List<Country>>(BackOfficeEndpoint.CountryEndpoint, "returnCountries");
}

Note that it's easier to work from the "inside out" rather than the "outside in" like this. In other words, don't start with an asynchronous controller action and then force downstream methods to be asynchronous. Instead, identify the naturally asynchronous operations (calling external APIs, database queries, etc), and make those asynchronous at the lowest level first (Service.ProcessAsync). Then let the async trickle up, making your controller actions asynchronous as the last step.

And under no circumstances should you use Task.Run in this scenario.

Expanding on Josh's benchmark... one can improve the clz as follows

/***************** clz2 ********************/

#define NUM_OF_HIGHESTBITclz2(a) ((a)                              \
                  ? (((1U) << (sizeof(unsigned)*8-1)) >> __builtin_clz(a)) \
                  : 0)

Regarding the asm: note that there are bsr and bsrl (this is the "long" version). the normal one might be a bit faster.

Insert this code in your .htaccess file. And it should work

RewriteCond %{HTTP_HOST} yourDomainName\.com [NC]
RewriteCond %{SERVER_PORT} 80
RewriteRule ^(.*)$ https://yourDomainName.com/$1 [R,L]

    //load css first, then print <link> to header, and execute callback
    //just set var href above this..
    $.ajax({
          url: href,
          dataType: 'css',
          success: function(){                  
                $('<link rel="stylesheet" type="text/css" href="'+href+'" />').appendTo("head");
                //your callback
            }
    });

For Jquery 1.2.6 and above ( omitting the fancy attributes functions above ).

I am doing it this way because I think that this will ensure that your requested stylesheet is loaded by ajax before you try to stick it into the head. Therefore, the callback is executed after the stylesheet is ready.

The issue in my case was a typo in the PATH variable. Since vsvars32.bat uses the "reg" tool to query the registry, it was failing because the tool was not found (just typing reg on a command prompt was failing for me).

FileUtils is class from apache org.apache.commons.io package, you need to download org.apache.commons.io.jar and then configure that jar file in your class path.

No. NodeJS is not available as an Apache module in the way mod-perl and mod-php are, so it's not possible to run node "on top of" Apache. As hexist pointed out, it's possible to run node as a separate process and arrange communication between the two, but this is quite different to the LAMP stack you're already using.

As a replacement for Apache, node offers performance advantages if you have many simultaneous connections. There's also a huge ecosystem of modules for almost anything you can think of.

From your question, it's not clear if you need to dynamically generate pages on every request, or just generate new content periodically for caching and serving. If its the latter, you could use separate node task to generate content to a directory that Apache would serve, but again, that's quite different to PHP or Perl.

Node isn't the best way to serve static content. Nginx and Varnish are more effective at that. They can serve static content while Node handles the dynamic data.

If you're considering using node for a web application at all, Express should be high on your list. You could implement a web application purely in Node, but Express (and similar frameworks like Flatiron, Derby and Meteor) are designed to take a lot of the pain and tedium away. Although the Express documentation can seem a bit sparse at first, check out the screen casts which are still available here: http://expressjs.com/2x/screencasts.html They'll give you a good sense of what express offers and why it is useful. The github repository for ExpressJS also contains many good examples for everything from authentication to organizing your app.

As was written above, if the language you use has a JSON-library coming with it, use it to try decoding the string and catch the exception/error if it fails! If the language does not (just had such a case with FreeMarker) the following regex could at least provide some very basic validation (it's written for PHP/PCRE to be testable/usable for more users). It's not as foolproof as the accepted solution, but also not that scary =):

~^\{\s*\".*\}$|^\[\n?\{\s*\".*\}\n?\]$~s

short explanation:

// we have two possibilities in case the string is JSON
// 1. the string passed is "just" a JSON object, e.g. {"item": [], "anotheritem": "content"}
// this can be matched by the following regex which makes sure there is at least a {" at the
// beginning of the string and a } at the end of the string, whatever is inbetween is not checked!

^\{\s*\".*\}$

// OR (character "|" in the regex pattern)
// 2. the string passed is a JSON array, e.g. [{"item": "value"}, {"item": "value"}]
// which would be matched by the second part of the pattern above

^\[\n?\{\s*\".*\}\n?\]$

// the s modifier is used to make "." also match newline characters (can happen in prettyfied JSON)

if I missed something that would break this unintentionally, I'm grateful for comments!

Use casting of types:

int main() {
    int a;
    float b, c, d;
    a = 750;
    b = a / (float)350;
    c = 750;
    d = c / (float)350;
    printf("%.2f %.2f", b, d);
    // output: 2.14 2.14
}

This is another way to solve that:

 int main() {
        int a;
        float b, c, d;
        a = 750;
        b = a / 350.0; //if you use 'a / 350' here, 
                       //then it is a division of integers, 
                       //so the result will be an integer
        c = 750;
        d = c / 350;
        printf("%.2f %.2f", b, d);
        // output: 2.14 2.14
    }

However, in both cases you are telling the compiler that 350 is a float, and not an integer. Consequently, the result of the division will be a float, and not an integer.

If you are using RestTemplate to make http calls Simply add an interceptor. Response body is cached by the implementation of ClientHttpResponse. Now inputstream can be retrieved from respose as many times as we need

ClientHttpRequestInterceptor interceptor =  new ClientHttpRequestInterceptor() {

            @Override
            public ClientHttpResponse intercept(HttpRequest request, byte[] body,
                    ClientHttpRequestExecution execution) throws IOException {
                ClientHttpResponse  response = execution.execute(request, body);

                  // additional work before returning response
                  return response 
            }
        };

    // Add the interceptor to RestTemplate Instance 

         restTemplate.getInterceptors().add(interceptor); 

i think u miss understand about table relation..

users : scores = 1 : *

just join is not a solution.

is this your intention?

SELECT users.username, avg(scores.point), avg(scores.avg_time)
FROM scores, users
WHERE scores.user_id = users.id
GROUP BY users.username
ORDER BY avg(scores.point) DESC, avg(scores.avg_time)
LIMIT 0, 20

(this query to get each users average point and average avg_time by desc point, asc )avg_time

if you want to get each scores ranking? use left outer join

SELECT users.username, scores.point, scores.avg_time
FROM scores left outer join users on scores.user_id = users.id
ORDER BY scores.point DESC, scores.avg_time
LIMIT 0, 20

Try this request:

Query

SELECT name
FROM   sys.procedures
WHERE  Object_definition(object_id) LIKE '%strHell%'

Update

the library already have Java/Kotlin support, see github.

To simplify I did a class to be used simply, I added it on Encryption library to use it you just do as follow:

Add the gradle library:

compile 'se.simbio.encryption:library:2.0.0'

and use it:

Encryption encryption = Encryption.getDefault("Key", "Salt", new byte[16]);
String encrypted = encryption.encryptOrNull("top secret string");
String decrypted = encryption.decryptOrNull(encrypted);

if you not want add the Encryption library you can just copy the following class to your project. If you are in an android project you need to import android Base64 in this class, if you are in a pure java project you need to add this class manually you can get it here

Talking about .hpp extension, I find it useful when people are supposed to know that this header file contains C++ an not C, like using namespaces or template etc, by the moment they see the files, so they won't try to feed it to a C compiler! And I also like to name header files which contain not only declarations but implementations as well, as .hpp files. like header files including template classes. Although that's just my opinion and of course it's not supposed to be right! :)

private void releaseObject(object obj)
{
    try
    {
        System.Runtime.InteropServices.Marshal.ReleaseComObject(obj);
        obj = null;
    }
    catch (Exception ex)
    {
        obj = null;
        MessageBox.Show("Unable to release the Object " + ex.ToString());
    }
    finally
    {
        GC.Collect();
    }
}

If you want new columns showing year and month separately you can do this:

df['year'] = pd.DatetimeIndex(df['ArrivalDate']).year
df['month'] = pd.DatetimeIndex(df['ArrivalDate']).month

or...

df['year'] = df['ArrivalDate'].dt.year
df['month'] = df['ArrivalDate'].dt.month

Then you can combine them or work with them just as they are.

It means your Class reference can hold a reference to any Class object.

It's basically the same as "Class" but you're showing other people who read your code that you didn't forget about generics, you just want a reference that can hold any Class object.

Bruce Eckel, Thinking in Java:

In Java SE5, Class<?> is preferred over plain Class, even though they are equivalent and the plain Class, as you saw, doesn’t produce a compiler warning. The benefit of Class<?> is that it indicates that you aren’t just using a non-specific class reference by accident, or out of ignorance. You chose the non-specific version.

I like @jesterjunk answer, however, a number is not always just digits. Consider those valid numbers: "123.5, 123,567.789, 12233234+E12"

So I just updated the regular expression:

var regex = /[\d|,|.|e|E|\+]+/g;

var string = "you can enter maximum 5,123.6 choices";
var matches = string.match(regex);  // creates array from matches

document.write(matches); //5,123.6

Simply because CPU/ABI says "No system images installed for this target". You need to install system images.

In the Android SDK Manager check that you have installed "ARM EABI v7a System Image" (for each Android version from 4.0 and on you have to install a system image to be able to run a virtual device)

In your case only ARM system image exsits (Android 4.2). If you were running an older version, Intel has provided System Images (Intel x86 ATOM). You can check on the internet to see the comparison in performance between both.

In my case (see image below) I haven't installed a System Image for Android 4.2, whereas I have installed ARM and Intel System Images for 4.1.2

As long as I don't install the 4.2 System Image I would have the same problem as you.

UPDATE : This recent article Speeding Up the Android Emaulator on Intel Architectures explains how to use/install correctly the intel system images to speed up the emulator.

EDIT/FOLLOW UP

What I show in the picture is for Android 4.2, as it was the original question, but is true for every versions of Android.

Of course (as @RedPlanet said), if you are developing for MIPS CPU devices you have to install the "MIPS System Image".

Finally, as @SeanJA said, you have to restart eclipse to see the new installed images. But for me, I always restart a software which I updated to be sure it takes into account all the modifications, and I assume it is a good practice to do so.

var a = ['a','b','c'];
var b = ['d','e','f'];
var c = a.concat(b); //c is now an an array with: ['a','b','c','d','e','f']
console.log( c[3] ); //c[3] will be 'd'

We can solve this issue so easily.

1. Open a command prompt, and do cd <platform-tools directory>
2. Run command adb kill-server
3. Open Windows Task manager and check whether adb is still running. If it is, just kill adb.exe
4. Run command adb start-server in the command prompt

public String substring(int beginIndex, int endIndex)

beginIndex—the begin index, inclusive.

endIndex—the end index, exclusive.

Example:

public class Test {

    public static void main(String args[]) {
        String Str = new String("Hello World");

        System.out.println(Str.substring(3, 8));
    }
 }

Output: "lo Wo"

From 3 to 7 index.

Also there is another kind of substring() method:

public String substring(int beginIndex)

beginIndex—the begin index, inclusive. Returns a sub string starting from beginIndex to the end of the main String.

Example:

public class Test {

    public static void main(String args[]) {
        String Str = new String("Hello World");

        System.out.println(Str.substring(3));
    }
}

Output: "lo World"

From 3 to the last index.

I also prefer Criteria Queries for dynamic queries. But I prefer hql for delete queries, for example if delete all records from child table for parent id 'xyz', It is easily achieved by HQL, but for criteria API first we must fire n number of delete query where n is number of child table records.

Use a parameterized query to prevent Sql injections (secutity problem)

Use the using statement so the connection will be closed and resources will be disposed.

using(var connection = new SqlConnection("connectionString"))
{
    connection.Open();
    var sql = "INSERT INTO Main(FirstName, SecondName) VALUES(@FirstName, @SecondName)";
    using(var cmd = new SqlCommand(sql, connection))
    {
        cmd.Parameters.AddWithValue("@FirstName", txFirstName.Text);
        cmd.Parameters.AddWithValue("@SecondName", txSecondName.Text);

        cmd.ExecuteNonQuery();
    }
}

Different solution that I find more elegant

Here's another way to do it. Some people will prefer this as the code is a bit cleaner. There are no %s and a RESET color to end the coloration.

#include <stdio.h>

#define RED   "\x1B[31m"
#define GRN   "\x1B[32m"
#define YEL   "\x1B[33m"
#define BLU   "\x1B[34m"
#define MAG   "\x1B[35m"
#define CYN   "\x1B[36m"
#define WHT   "\x1B[37m"
#define RESET "\x1B[0m"

int main() {
  printf(RED "red\n"     RESET);
  printf(GRN "green\n"   RESET);
  printf(YEL "yellow\n"  RESET);
  printf(BLU "blue\n"    RESET);
  printf(MAG "magenta\n" RESET);
  printf(CYN "cyan\n"    RESET);
  printf(WHT "white\n"   RESET);

  return 0;
}

This program gives the following output:

Simple example with multiple colors

This way, it's easy to do something like:

printf("This is " RED "red" RESET " and this is " BLU "blue" RESET "\n");

This line produces the following output:

A simpler approach like the one Ioannis Filippidis do :

import matplotlib.pyplot as plt
import numpy as np

# evenly sampled time at 200ms intervals
tMin=-1 ;tMax=10
t = np.arange(tMin, tMax, 0.1)

# red dashes, blue points default
plt.plot(t, 22*t, 'r--', t, t**2, 'b')

factor=3/4 ;offset=20  # text position in view  
textPosition=[(tMax+tMin)*factor,22*(tMax+tMin)*factor]
plt.text(textPosition[0],textPosition[1]+offset,'22  t',color='red',fontsize=20)
textPosition=[(tMax+tMin)*factor,((tMax+tMin)*factor)**2+20]
plt.text(textPosition[0],textPosition[1]+offset, 't^2', bbox=dict(facecolor='blue', alpha=0.5),fontsize=20)
plt.show()

code python 3 on sageCell

You could potentially write a helper method which returned an empty sequence if you passed in null:

public static <T> Iterable<T> emptyIfNull(Iterable<T> iterable) {
    return iterable == null ? Collections.<T>emptyList() : iterable;
}

Then use:

for (Object object : emptyIfNull(someList)) {
}

I don't think I'd actually do that though - I'd usually use your second form. In particular, the "or throw ex" is important - if it really shouldn't be null, you should definitely throw an exception. You know that something has gone wrong, but you don't know the extent of the damage. Abort early.

Would like to add:

After update, such as

ALTER TABLE table_name modify column_name tinyint(4) NOT NULL;

If you get

ERROR 1138 (22004): Invalid use of NULL value

Make sure you update the table first to have values in the related column (so it's not null)

Update April 2019

jQuery isn't needed for cookie reading/manipulation, so don't use the original answer below.

Go to https://github.com/js-cookie/js-cookie instead, and use the library there that doesn't depend on jQuery.

Basic examples:

// Set a cookie
Cookies.set('name', 'value');

// Read the cookie
Cookies.get('name') => // => 'value'

See the docs on github for details.

Before April 2019 (old)

See the plugin:

https://github.com/carhartl/jquery-cookie

You can then do:

$.cookie("test", 1);

To delete:

$.removeCookie("test");

Additionally, to set a timeout of a certain number of days (10 here) on the cookie:

$.cookie("test", 1, { expires : 10 });

If the expires option is omitted, then the cookie becomes a session cookie and is deleted when the browser exits.

To cover all the options:

$.cookie("test", 1, {
   expires : 10,           // Expires in 10 days

   path    : '/',          // The value of the path attribute of the cookie
                           // (Default: path of page that created the cookie).

   domain  : 'jquery.com', // The value of the domain attribute of the cookie
                           // (Default: domain of page that created the cookie).

   secure  : true          // If set to true the secure attribute of the cookie
                           // will be set and the cookie transmission will
                           // require a secure protocol (defaults to false).
});

To read back the value of the cookie:

var cookieValue = $.cookie("test");

You may wish to specify the path parameter if the cookie was created on a different path to the current one:

var cookieValue = $.cookie("test", { path: '/foo' });

UPDATE (April 2015):

As stated in the comments below, the team that worked on the original plugin has removed the jQuery dependency in a new project (https://github.com/js-cookie/js-cookie) which has the same functionality and general syntax as the jQuery version. Apparently the original plugin isn't going anywhere though.

The #include directive literally means "copy all the data in that file to this spot." So when you include the header file, it's textually within the code file, and everything in it will be there, give or take the effect of other directives or macro replacements, when the code file (now called the compilation unit or translation unit) is handed off from the preprocessor module to the compiler module.

Which means the declaration and definition of your static member function were really in the same file all along...

In the latter case, if obj is null you won't get a NullPointerException but a false.

this is my solution, you can set on an item (or a group) and deselect it with another click:

 private final ArrayList<Integer> seleccionados = new ArrayList<>();
@Override
    public void onBindViewHolder(final ViewHolder viewHolder, final int i) {
        viewHolder.san.setText(android_versions.get(i).getAndroid_version_name());
        if (!seleccionados.contains(i)){ 
            viewHolder.inside.setCardBackgroundColor(Color.LTGRAY);
        }
        else {
            viewHolder.inside.setCardBackgroundColor(Color.BLUE);
        }
        viewHolder.itemView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                if (seleccionados.contains(i)){
                    seleccionados.remove(seleccionados.indexOf(i)); 
                    viewHolder.inside.setCardBackgroundColor(Color.LTGRAY);
                } else { 
                    seleccionados.add(i);
                    viewHolder.inside.setCardBackgroundColor(Color.BLUE);
                }
            }
        });
    }

Maybe specifying a width would work. When you position:absolute an element, it's width will shrink to the contents I believe.

Use LD_PRELOAD: put your library somewhere out of the man lib directories and run:

LD_PRELOAD='mylibc.so anotherlib.so' program

The best way to view and manage your Android app database is to use the library DatabaseManager_For_Android.

It's a single Java activity file; just add it to your source folder. You can view the tables in your app database, update, delete, insert rows to you table. Everything from inside your app.

When the development is done remove the Java file from your src folder. That's it.

You can view the 5 minute demo, Database Manager for Android SQLite Database .

As described here input and output extension will detected by ffmpeg so there is no need to worry about the formats, simply run this command:

ffmpeg -i inputFile.ogg outputFile.mp3

To supply an example of why it has to be a string:

If you format 1.toFixed(2) you would get '1.00'.

This is not the same as 1, as 1 does not have 2 decimals.

I know JavaScript isn't exactly a performance language, but chances are you'd get better performance for a rounding if you use something like: roundedValue = Math.round(value * 100) * 0.01

GAC = Global Assembly Cache

Let's break it down:

• global - applies to the entire machine
• assembly - what .NET calls its code-libraries (DLLs)
• cache - a place to store things for faster/common access

So the GAC must be a place to store code libraries so they're accessible to all applications running on the machine.

I think the best response is from the user @b1nary.atr0phy. Somehow, I recommend combine the method from the b1nay.atr0phy response with a regex to cover all the possible cases.

public static final URL validateURL(String url, Logger logger) {

        URL u = null;
        try {  
            Pattern regex = Pattern.compile("(?i)^(?:(?:https?|ftp)://)(?:\\S+(?::\\S*)?@)?(?:(?!(?:10|127)(?:\\.\\d{1,3}){3})(?!(?:169\\.254|192\\.168)(?:\\.\\d{1,3}){2})(?!172\\.(?:1[6-9]|2\\d|3[0-1])(?:\\.\\d{1,3}){2})(?:[1-9]\\d?|1\\d\\d|2[01]\\d|22[0-3])(?:\\.(?:1?\\d{1,2}|2[0-4]\\d|25[0-5])){2}(?:\\.(?:[1-9]\\d?|1\\d\\d|2[0-4]\\d|25[0-4]))|(?:(?:[a-z\\u00a1-\\uffff0-9]-*)*[a-z\\u00a1-\\uffff0-9]+)(?:\\.(?:[a-z\\u00a1-\\uffff0-9]-*)*[a-z\\u00a1-\\uffff0-9]+)*(?:\\.(?:[a-z\\u00a1-\\uffff]{2,}))\\.?)(?::\\d{2,5})?(?:[/?#]\\S*)?$");
            Matcher matcher = regex.matcher(url);
            if(!matcher.find()) {
                throw new URISyntaxException(url, "La url no está formada correctamente.");
            }
            u = new URL(url);  
            u.toURI(); 
        } catch (MalformedURLException e) {  
            logger.error("La url no está formada correctamente.");
        } catch (URISyntaxException e) {  
            logger.error("La url no está formada correctamente.");  
        }  

        return u;  

    }

Throw a new exception on server using:

Response.StatusCode = 500

Response.StatusDescription = ex.Message()

I believe that the StatusDescription is returned to the Ajax call...

Example:

        Try

            Dim file As String = Request.QueryString("file")

            If String.IsNullOrEmpty(file) Then Throw New Exception("File does not exist")

            Dim sTmpFolder As String = "Temp\" & Session.SessionID.ToString()

            sTmpFolder = IO.Path.Combine(Request.PhysicalApplicationPath(), sTmpFolder)

            file = IO.Path.Combine(sTmpFolder, file)

            If IO.File.Exists(file) Then

                IO.File.Delete(file)

            End If

        Catch ex As Exception

            Response.StatusCode = 500

            Response.StatusDescription = ex.Message()

        End Try

How about one of the many wikis?

Kenny: I've used FlexWiki & ScrewTurn (abandoned).

someone else with RepPower to edit my post added this.
Wikipedia is powered by MediaWiki.

When creating a JQuery Dialog window, JQuery inserts a ui-widget-overlay class. If you bind a click function to that class to close the dialog, it should provide the functionality you are looking for.

Code will be something like this (untested):

$('.ui-widget-overlay').click(function() { $("#dialog").dialog("close"); });

Edit: The following has been tested for Kendo as well:

$('.k-overlay').click(function () {
            var popup = $("#dialogId").data("kendoWindow");
            if (popup)
                popup.close();
        });

Three ways you can do this - from the form designer, select the form, and where you normally see the list of properties, just above it there should be a little lightning symbol - this shows you all the events of the form. Find the form load event in the list, and you should be able to pick ProgramViwer_Load from the dropdown.

A second way to do it is programmatically - somewhere (constructor maybe) you'd need to add it, something like: ProgramViwer.Load += new EventHandler(ProgramViwer_Load);

A third way using the designer (probably the quickest) - when you create a new form, double click on the middle of it on it in design mode. It'll create a Form load event for you, hook it in, and take you to the event handler code. Then you can just add your two lines and you're good to go!

You can also concatenate strings from across multiple lines with whitespaces.

$ cat file.txt
apple 10
oranges 22
grapes 7

Example 1:

awk '{aggr=aggr " " $2} END {print aggr}' file.txt
10 22 7

Example 2:

awk '{aggr=aggr ", " $1 ":" $2} END {print aggr}' file.txt
, apple:10, oranges:22, grapes:7

Although this may be more complicated/heavier-weight than you want, one very flexible way to do it is using something like Expect (or one of the derivatives in another programming language).

Expect is a language designed specifically to control text-based applications, which is exactly what you are looking to do. If you end up needing to do something more complicated (like with logic to actually decide what to do/answer next), Expect is the way to go.

I know you asked to Rebase, but I'd Cherry-Pick the commits I wanted to move from Branch2 to Branch1 instead. That way, I wouldn't need to care about when which branch was created from master, and I'd have more control over the merging.

a -- b -- c                  <-- Master
     \     \
      \     d -- e -- f -- g <-- Branch1 (Cherry-Pick f & g)
       \
        f -- g               <-- Branch2

If it's not important to use a RelativeLayout, you could use a LinearLayout, and do this:

LinearLayout linearLayout = new LinearLayout(this);
linearLayout.setOrientation(LinearLayout.VERTICAL);

Doing this allows you to avoid the addRule method you've tried. You can simply use addView() to add new TextViews.

Complete code:

String[] textArray = {"One", "Two", "Three", "Four"};
LinearLayout linearLayout = new LinearLayout(this);
setContentView(linearLayout);
linearLayout.setOrientation(LinearLayout.VERTICAL);        
for( int i = 0; i < textArray.length; i++ )
{
    TextView textView = new TextView(this);
    textView.setText(textArray[i]);
    linearLayout.addView(textView);
}

I don't think there's any way to get width of texts in variable-width fonts, especially in javascript.

The only way I can think is to make a hidden element that has variable width set by css, put text in its innerHTML, and get the width of that element. So you may be able to apply this method to cope with textarea auto-sizing problem.

Differences between an XML Schema Definition (XSD) and Document Type Definition (DTD) include:

• XML schemas are written in XML while DTD are derived from SGML syntax.
• XML schemas define datatypes for elements and attributes while DTD doesn't support datatypes.
• XML schemas allow support for namespaces while DTD does not.
• XML schemas define number and order of child elements, while DTD does not.
• XML schemas can be manipulated on your own with XML DOM but it is not possible in case of DTD.
• using XML schema user need not to learn a new language but working with DTD is difficult for a user.
• XML schema provides secure data communication i.e sender can describe the data in a way that receiver will understand, but in case of DTD data can be misunderstood by the receiver.
• XML schemas are extensible while DTD is not extensible.

Not all these bullet points are 100% accurate, but you get the gist.

On the other hand:

• DTD lets you define new ENTITY values for use in your XML file.
• DTD lets you extend it local to an individual XML file.

Simply you can use the following code:

$arr=explode('sep1',str_replace(array('sep2','sep3','sep4'),'sep1',$mystring));

This works in IE9 (Compatibility View and Normal Mode), Firefox 17, and Chrome 23:

<table>
    <tr>
        <td style="background-image:url(untitled.png); background-position:right 0px; background-repeat:no-repeat;">
            Hello World
        </td>
    </tr>
</table>

You didn't use FROM expression for a table

SELECT DISTINCT Description, Date as treatmentDate
**FROM <A TABLE>**
WHERE doothey.Patient P, doothey.Account A, doothey.AccountLine AL, doothey.Item.I
AND P.PatientID = A.PatientID
AND A.AccountNo = AL.AccountNo
AND AL.ItemNo = I.ItemNo

For a simple Spring application, you don't have to define ContextLoaderListener in your web.xml; you can just put all your Spring configuration files in <servlet>:

<servlet>
    <servlet-name>hello</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:spring/mvc-core-config.xml, classpath:spring/business-config.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>

For a more complex Spring application, where you have multiple DispatcherServlet defined, you can have the common Spring configuration files that are shared by all the DispatcherServlet defined in the ContextLoaderListener:

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:spring/common-config.xml</param-value>
</context-param>
<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

<servlet>
    <servlet-name>mvc1</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:spring/mvc1-config.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>

<servlet>
    <servlet-name>mvc2</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:spring/mvc2-config.xmll</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>

Just keep in mind, ContextLoaderListener performs the actual initialization work for the root application context.

I found this article helps a lot: Spring MVC – Application Context vs Web Application Context

You can use a simple, low-cost USB port reader like this test connects directly to your Android device; it has a utility app and an SDK you can use for app development: https://www.atlasrfidstore.com/sls-rfid-smartmicro-android-micro-usb-reader/

A JavaScript accordion does the trick.

This fiddle by W3Schools makes a simple task even more simple using nothing but javascript, which i partially reproduce below.

<head>
<style>
button.accordion {
    background-color: #eee;
    color: #444;
    font-size: 15px;
    cursor: pointer;
}

button.accordion.active, button.accordion:hover {
    background-color: #ddd; 
}

div.panel {
    padding: 0 18px;
    display: none;
    background-color: white;
}

div.panel.show {
    display: block;
}
</style>
</head><body>
<script>
var acc = document.getElementsByClassName("accordion");
var i;

for (i = 0; i < acc.length; i++) {
    acc[i].onclick = function(){
    this.classList.toggle("active");
    this.nextElementSibling.classList.toggle("show");
  }
}
</script>
...
<button class="accordion">Section 1</button>
<div class="panel">
  <p>Lorem ipsum dolor sit amet</p>
</div>
...
<button class="accordion">Table</button>
<div class="panel">
  <p><table name="detail_table">...</table></p>
</div>
...
<button class="accordion"><table name="button_table">...</table></button>
<div class="panel">
  <p>Lorem ipsum dolor sit amet</p>
  <table name="detail_table">...</table>
  <img src=...></img>
</div>
...
</body></html>

if using php, don't forget to convert " to '. You can also use tables of data inside the button and it will still work.

For small functions like this you could just count by hand how many hops it is to the target, from the instruction under the branch instruction. If it branches backwards make that hop number negative. if that number doesn't require all 16 bits, then for every number to the left of the most significant of your hop number, make them 1's, if the hop number is positive make them all 0's Since most branches are close to they're targets, this saves you a lot of extra arithmetic for most cases.

var obj = {
    'key1':'value',
    '2':'value',
    'key 1':'value'
}

console.log(obj.key1)
console.log(obj['key1'])
console.log(obj['2'])
console.log(obj['key 1'])

// will not work
console.log(obj.2)

Edit:

"I'm specifically looking to target the index, just like the first example - if it's possible."

Actually the 'index' is the key. If you want to store the position of a key you need to create a custom object to handle this.

In C++, the size of int isn't specified explicitly. It just tells you that it must be at least the size of short int, which must be at least as large as signed char. The size of char in bits isn't specified explicitly either, although sizeof(char) is defined to be 1. If you want a 64 bit int, C++11 specifies long long to be at least 64 bits.

Here is my working solution with search and clear icon for Angularjs\Bootstrap with CSS.

                            <span class="glyphicon glyphicon-search form-control-feedback"></span>
                        </div>
                        <div ng-switch-when="true">
                            <span class="glyphicon glyphicon-remove-sign form-control-feedback" ng-click="$parent.filter = ''" style="pointer-events: auto; text-decoration: none;cursor: pointer;"></span>

But you shouldn't

For my Apache2.4 + php5-fpm installation to start working, I needed to activate the following Apache modules:

sudo a2enmod proxy
sudo a2enmod proxy_fcgi

No need for proxy_http, and this is what sends all .php files straight to php5-fpm:

<FilesMatch \.php$>
    SetHandler "proxy:unix:/var/run/php5-fpm.sock|fcgi://localhost"
</FilesMatch>

I've made a category from @Abizern answer

@implementation NSString (Extensions)
- (NSDictionary *) json_StringToDictionary {
    NSError *error;
    NSData *objectData = [self dataUsingEncoding:NSUTF8StringEncoding];
    NSDictionary *json = [NSJSONSerialization JSONObjectWithData:objectData options:NSJSONReadingMutableContainers error:&error];
    return (!json ? nil : json);
}
@end

Use it like this,

NSString *jsonString = @"{\"2\":\"3\"}";
NSLog(@"%@",[jsonString json_StringToDictionary]);

I used /etc/crontab. I used vi and entered in the PATHs I needed into this file and ran it as root. The normal crontab overwrites PATHs that you have set up. A good tutorial on how to do this.

The systemwide cron file looks like this:

This has the username field, as used by /etc/crontab.
# /etc/crontab: system-wide crontab
# Unlike any other crontab you don't have to run the `crontab'
# command to install the new version when you edit this file.
# This file also has a username field, that none of the other crontabs do.

SHELL=/bin/sh
PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin

# m h dom mon dow user   command
42 6 * * *   root    run-parts --report /etc/cron.daily
47 6 * * 7   root    run-parts --report /etc/cron.weekly
52 6 1 * *   root    run-parts --report /etc/cron.monthly

The dash is a special character in Bash as noted at http://tldp.org/LDP/abs/html/special-chars.html#DASHREF. So escaping this once just gets you past Bash, but Grep still has it's own meaning to dashes (by providing options).

So you really need to escape it twice (if you prefer not to use the other mentioned answers). The following will/should work

grep \\-X
grep '\-X'
grep "\-X"

One way to try out how Bash passes arguments to a script/program is to create a .sh script that just echos all the arguments. I use a script called echo-args.sh to play with from time to time, all it contains is:

echo $*

I invoke it as:

bash echo-args.sh \-X
bash echo-args.sh \\-X
bash echo-args.sh "\-X"

You get the idea.

I am using wildfly 10 for javaee container . I had experienced "Target Unreachable, 'entity' returned null" issue. Thanks for suggestions by BalusC but the my issue out of the solutions explained. Accidentally using "import com.sun.istack.logging.Logger;" instead of "import org.jboss.logging.Logger;" caused CDI implemented JSF EL. Hope it helps to improve solution .

Try like this:

$.ajax({

    data: { 
        'foo': 'bar', 
        'ca$libri': 'no$libri' // <-- the $ sign in the parameter name seems unusual, I would avoid it

I did want to obmit a old big history and start from a fresh commit i choosed to:

rsync -a --exclude '.git' old-repo/ new-repo/
cd new-repo 
git push 

when now old-repo changes i can apply the patches to the new-repo to rebase them on the new-repo.

How about using <input type="number"...>?

Also, here is a question that has some examples of using Javascript for validation.

Update: linked to better question (thanks alexblum).

try creating connection string this way:

MySqlConnectionStringBuilder conn_string = new MySqlConnectionStringBuilder();
conn_string.Server = "mysql7.000webhost.com";
conn_string.UserID = "a455555_test";
conn_string.Password = "a455555_me";
conn_string.Database = "xxxxxxxx";

using (MySqlConnection conn = new MySqlConnection(conn_string.ToString()))
using (MySqlCommand cmd = conn.CreateCommand())
{    //watch out for this SQL injection vulnerability below
     cmd.CommandText = string.Format("INSERT Test (lat, long) VALUES ({0},{1})",
                                    OSGconv.deciLat, OSGconv.deciLon);
     conn.Open();
     cmd.ExecuteNonQuery();
}

It has to be a constant - the value has to be computable at the time that the procedure is created, and that one computation has to provide the value that will always be used.

Look at the definition of sys.all_parameters:

default_value sql_variant If has_default_value is 1, the value of this column is the value of the default for the parameter; otherwise, NULL.

That is, whatever the default for a parameter is, it has to fit in that column.

As Alex K pointed out in the comments, you can just do:

CREATE PROCEDURE [dbo].[problemParam] 
    @StartDate INT = NULL,
    @EndDate INT = NULL
AS  
BEGIN
   SET @StartDate = COALESCE(@StartDate,CONVERT(INT,(CONVERT(CHAR(8),GETDATE()-130,112))))

provided that NULL isn't intended to be a valid value for @StartDate.

As to the blog post you linked to in the comments - that's talking about a very specific context - that, the result of evaluating GETDATE() within the context of a single query is often considered to be constant. I don't know of many people (unlike the blog author) who would consider a separate expression inside a UDF to be part of the same query as the query that calls the UDF.

MVC 5/6/Razor Pages

I think the best way is with strongly typed model, because Viewbags are being aboused too much already :)

MVC 5 example

Your Get Action

public async Task<ActionResult> Register()
    {
        var model = new RegistrationViewModel
        {
            Roles = GetRoles()
        };

        return View(model);
    }

Your View Model

    public class RegistrationViewModel
    {
        public string Name { get; set; }

        public int? RoleId { get; set; }

        public List<SelectListItem> Roles { get; set; }
    }    

Your View

    <div class="form-group">
        @Html.LabelFor(model => model.RoleId, htmlAttributes: new { @class = "col-form-label" })
        <div class="col-form-txt">
            @Html.DropDownListFor(model => model.RoleId, Model.Roles, "--Select Role--", new { @class = "form-control" })
            @Html.ValidationMessageFor(model => model.RoleId, "", new { @class = "text-danger" })
        </div>
    </div>                                   

Your Post Action

    [HttpPost, ValidateAntiForgeryToken]
    public async Task<ActionResult> Register(RegistrationViewModel model)
    {
        if (ModelState.IsValid)
        {
            var _roleId = model.RoleId, 

MVC 6 It'll be a little different

Get Action

public async Task<ActionResult> Register()
    {
        var _roles = new List<SelectListItem>();
        _roles.Add(new SelectListItem
        {
           Text = "Select",
           Value = ""
        });
        foreach (var role in GetRoles())
        {
          _roles.Add(new SelectListItem
          {
            Text = z.Name,
            Value = z.Id
          });
        }

        var model = new RegistrationViewModel
        {
            Roles = _roles
        };

        return View(model);
    }

Your View Model will be same as MVC 5

Your View will be like

<select asp-for="RoleId" asp-items="Model.Roles"></select>

Post will also be same

Razor Pages

Your Page Model

[BindProperty]
public int User User { get; set; } = 1;

public List<SelectListItem> Roles { get; set; }

public void OnGet()
{
    Roles = new List<SelectListItem> {
        new SelectListItem { Value = "1", Text = "X" },
        new SelectListItem { Value = "2", Text = "Y" },
        new SelectListItem { Value = "3", Text = "Z" },
   };
}

<select asp-for="User" asp-items="Model.Roles">
    <option value="">Select Role</option>
</select>

I hope it may help someone :)

I hope this answer isn't late. Because the gallery widget doesn't support multiple selection by default, but you can custom the gridview which accepted your multiselect intent. The other option is to extend the gallery view and add in your own code to allow multiple selection.
This is the simple library can do it: https://github.com/luminousman/MultipleImagePick

Update:
From @ilsy's comment, CustomGalleryActivity in this library use manageQuery, which is deprecated, so it should be changed to getContentResolver().query() and cursor.close() like this answer

I have used below line of code and it works, Try this

DataTable dt =  dataSource.Tables[0];

Got the error (in the function init) with the following code ;

"use strict" ;

var hdr ;

function init(){ // called on load
    hdr = document.getElementById("hdr");
}

... while using the stock browser on a Samsung galaxy Fame ( crap phone which makes it a good tester ) - userAgent ; Mozilla/5.0 (Linux; U; Android 4.1.2; en-gb; GT-S6810P Build/JZO54K) AppleWebKit/534.30 (KHTML, like Gecko) Version/4.0 Mobile Safari/534.30

The same code works everywhere else I tried including the stock browser on an older HTC phone - userAgent ; Mozilla/5.0 (Linux; U; Android 2.3.5; en-gb; HTC_WildfireS_A510e Build/GRJ90) AppleWebKit/533.1 (KHTML, like Gecko) Version/4.0 Mobile Safari/533.1

The fix for this was to change

var hdr ;

to

var hdr = null ;

For me, these steps fixed the issue:

1- Running this cmd as admin:

npm install --global --production windows-build-tools

2- Then running npm rebuild after the 1st step is completed (especially completing the python 2.7 installation, which was the main cause of the issue)

If the query doesn't contain parameter, use OpenQuery else use OpenRowset.

Basic thing would be to create schema as per stored procedure and insert into that table. e.g.:

DECLARE @abc TABLE(
                  RequisitionTypeSourceTypeID INT
                , RequisitionTypeID INT
                , RequisitionSourcingTypeID INT
                , AutoDistOverride INT
                , AllowManagerToWithdrawDistributedReq INT
                , ResumeRequired INT
                , WarnSupplierOnDNRReqSubmission  INT
                , MSPApprovalReqd INT
                , EnableMSPSupplierCounterOffer INT
                , RequireVendorToAcceptOffer INT
                , UseCertification INT
                , UseCompetency INT
                , RequireRequisitionTemplate INT
                , CreatedByID INT
                , CreatedDate DATE
                , ModifiedByID INT
                , ModifiedDate DATE
                , UseCandidateScheduledHours INT
                , WeekEndingDayOfWeekID INT
                , AllowAutoEnroll INT
                )
INSERT INTO @abc
EXEC [dbo].[usp_MySp] 726,3
SELECT * FROM @abc

I've only tested with AdBlock... if the ads.js file solution won't work for you, this may..

Somewhere in your <body> add:

<div class="ads-wrapper adTop adUnit"></div>

then you can detect if AdBlock is enabled after DOM ready and then trigger whatever you intend to do:

var adBlockDetected = null;
$(document).ready(function() {
    setTimeout(function() {
        adBlockDetected = !$('.ads-wrapper').length > 0 || !$('.ads-wrapper').is(':visible');

        if (adBlockDetected) {
            $(document).trigger('adblock-detected');
        }
    }, 1000); // give adblock time to do what it does best
});

$(document).on('adblock-detected', function() {
    // ... your code here
});

The following "work-around" retains the CRLF and supports pasting data with CRLF characters into Excel without breaking column data into multiple lines. It will require replacing "select *" with named columns and any double-quotes in the data will be replaced with the delimiter value.

declare @delimiter char(1)
set @delimiter = '|'

declare @double_quote char(1)
set @double_quote = '"'

declare @text varchar(255)
set @text = 'This
"is"
a
test'

-- This query demonstrates the problem.  Execute the query and then copy/paste into Excel.
SELECT @text

-- This query demonstrates the solution.
SELECT @double_quote + REPLACE(@text, @double_quote, @delimiter) + @double_quote

Got the answer :

SELECT * FROM DBA_ROLES;

Apache is not running

It could also be something as simple as Apache not being configured to start automatically on boot. Assuming you are on a Red Hat-like system such as CentOS or Fedora, the chkconfig –list command will show you which services are set to start for each runlevel. You should see a line like

    httpd           0:off   1:off   2:on    3:on    4:on    5:on    6:off

If instead it says "off" all the way across, you can activate it with chkconfig httpd on. OR you can start apache manually from your panel.

This is the error line:

if (called_from.equalsIgnoreCase("add")) {  --->38th error line

This means that called_from is null. Simple check if it is null above:

String called_from = getIntent().getStringExtra("called");

if(called_from == null) {
    called_from = "empty string";
}
if (called_from.equalsIgnoreCase("add")) {
    // do whatever
} else {
    // do whatever
}

That way, if called_from is null, it'll execute the else part of your if statement.

Ubuntu comes with a version of PIP from precambrian and that's how you have to upgrade it if you do not want to spend hours and hours debugging pip related issues.

apt-get remove python-pip python3-pip
wget https://bootstrap.pypa.io/get-pip.py
python get-pip.py
python3 get-pip.py

As you observed I included information for both Python 2.x and 3.x

none of the suggested solutions above worked for me but this technique solved the issue:

$('#myModal').on('shown.bs.modal', function() {
   //To relate the z-index make sure backdrop and modal are siblings
   $(this).before($('.modal-backdrop'));
   //Now set z-index of modal greater than backdrop
   $(this).css("z-index", parseInt($('.modal-backdrop').css('z-index')) + 1);
}); 

encodeURIComponent(Your text here);

This will truncate special characters.

I run my system on top of a XAMPP instalation on a OS X.

A few days ago I faced the same problem. I was getting a lot of permission problems when installing and managing CMS test platforms, so I decided to set the entire htdocs subtree to a+rwX permissions, and got the same error.

Although my decision to set the entire subtree to those permissions is generally a mistake, that I made knowingly because this system is only accessable by localhost and otherwise unreachable, the only file that needs permission changing to solve this issue is config.inc.php, and you can leave the rest with the permissions you think you need.

The problem is fixed with:
chmod 644 config.inc.php, or sudo chmod 644 config.inc.php, depending on the system. (issued inside the phpmyadmin folder)

Just in case someone comes here trying to know how to create a tuple assigning each part of the string "Quattro" and "TT" to an element of the list, it would be like this print tuple(a.split())

From http://www.codeave.com/javascript/code.asp?u_log=7004:

<input id="myTextInput" value="Hello world!" />

To address the --rebase vs. --merge option:

Let's say you have super repository A and submodule B and want to do some work in submodule B. You've done your homework and know that after calling

git submodule update

you are in a HEAD-less state, so any commits you do at this point are hard to get back to. So, you've started work on a new branch in submodule B

cd B
git checkout -b bestIdeaForBEver
<do work>

Meanwhile, someone else in project A has decided that the latest and greatest version of B is really what A deserves. You, out of habit, merge the most recent changes down and update your submodules.

<in A>
git merge develop
git submodule update

Oh noes! You're back in a headless state again, probably because B is now pointing to the SHA associated with B's new tip, or some other commit. If only you had:

git merge develop
git submodule update --rebase

Fast-forwarded bestIdeaForBEver to b798edfdsf1191f8b140ea325685c4da19a9d437.
Submodule path 'B': rebased into 'b798ecsdf71191f8b140ea325685c4da19a9d437'

Now that best idea ever for B has been rebased onto the new commit, and more importantly, you are still on your development branch for B, not in a headless state!

(The --merge will merge changes from beforeUpdateSHA to afterUpdateSHA into your working branch, as opposed to rebasing your changes onto afterUpdateSHA.)

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).

You can also do it by checking if View's indexOfView method if indexOfView method returns -1 then we can use.

ViewGroup's detachViewFromParent(v); followed by ViewGroup's removeDetachedView(v, true/false);

You can use the annotate command to place text annotations at any x and y values you want. To place them exactly at the data points you could do this

import numpy
from matplotlib import pyplot

x = numpy.arange(10)
y = numpy.array([5,3,4,2,7,5,4,6,3,2])

fig = pyplot.figure()
ax = fig.add_subplot(111)
ax.set_ylim(0,10)
pyplot.plot(x,y)
for i,j in zip(x,y):
    ax.annotate(str(j),xy=(i,j))

pyplot.show()

If you want the annotations offset a little, you could change the annotate line to something like

ax.annotate(str(j),xy=(i,j+0.5))

I think ResponseEntityExceptionHandler meets your requirements. A sample piece of code for HTTP 400:

@ControllerAdvice
public class MyExceptionHandler extends ResponseEntityExceptionHandler {

  @ResponseStatus(value = HttpStatus.BAD_REQUEST)
  @ExceptionHandler({HttpMessageNotReadableException.class, MethodArgumentNotValidException.class,
      HttpRequestMethodNotSupportedException.class})
  public ResponseEntity<Object> badRequest(HttpServletRequest req, Exception exception) {
    // ...
  }
}

Something like this will do it:

Rows("12:12").Select
Selection.Delete

So in your code it would look like something like this:

Rows(CStr(rand) & ":" & CStr(rand)).Select
Selection.Delete

If you don't see the web.xml file in WEB-INF folder,

- Select Deployment Descriptor and right click on it.
- Then select the Generate Deployment Descriptor Stub

Finally you get web.xml file.

You could use something like Grunt Include Source. It gives you a nice syntax that preprocesses your HTML, and then includes whatever you want. This also means, if you set up your build tasks correctly, you can have all these includes in dev mode, but not in prod mode, which is pretty cool.

If you aren't using Grunt for your project, there's probably similar tools for Gulp, or other task runners.

This kind of functionality is built in.

When using a decimal you can use a format string "C" or "c".

decimal dec = 123.00M;
string uk = dec.ToString("C", new CultureInfo("en-GB")); // uk holds "£123.00"
string us = dec.ToString("C", new CultureInfo("en-US")); // us holds "$123.00"

FYI. You can now just update VS 2012:

http://blogs.msdn.com/b/webdev/archive/2013/11/18/announcing-release-of-asp-net-and-web-tools-2013-1-for-visual-studio-2012.aspx

"We have released ASP.NET and Web Tools 2013.1 for Visual Studio 2012. This release brings a ton of great improvements, and include some fantastic enhancements to ASP.NET MVC 5, Web API 2, Scaffolding and Entity Framework to users of Visual Studio 2012 and Visual Studio 2012 Express for Web."

Use the 'EntireColumn' property, that's what it is there for. C# snippet, but should give you a good indication of how to do this:

string rangeQuery = "A1:A1";

Range range = workSheet.get_Range(rangeQuery, Type.Missing);

range = range.EntireColumn;

I am using Oracle Database and i had same problem. Eventually i found ORACLE DB is converting all the metadata (table/sp/view/trigger) in upper case.

And i was trying how i wrote table name (myTempTable) in sql whereas it expect how it store table name in databsae (MYTEMPTABLE). Also same applicable on column name.

It is quite common problem with developer whoever used sql and now jumped into ORACLE DB.

Beware that when the mounted event is fired on a component, not all Vue components are replaced yet, so the DOM may not be final yet.

To really simulate the DOM onload event, i.e. to fire after the DOM is ready but before the page is drawn, use vm.$nextTick from inside mounted:

mounted: function () {
  this.$nextTick(function () {
    // Will be executed when the DOM is ready
  })
}
