In some previous backups, your bad objects may have been packed in different files or may be loose objects yet. So your objects may be recovered.

It seems there are a few bad objects in your database. So you could do it the manual way.

Because of git hash-object, git mktree and git commit-tree do not write the objects because they are found in the pack, then start doing this:

mv .git/objects/pack/* <somewhere>
for i in <somewhere>/*.pack; do
  git unpack-objects -r < $i
done
rm <somewhere>/*

(Your packs are moved out from the repository, and unpacked again in it; only the good objects are now in the database)

You can do:

git cat-file -t 6c8cae4994b5ec7891ccb1527d30634997a978ee

and check the type of the object.

If the type is blob: retrieve the contents of the file from previous backups (with git show or git cat-file or git unpack-file; then you may git hash-object -w to rewrite the object in your current repository.

If the type is tree: you could use git ls-tree to recover the tree from previous backups; then git mktree to write it again in your current repository.

If the type is commit: the same with git show, git cat-file and git commit-tree.

Of course, I would backup your original working copy before starting this process.

Also, take a look at How to Recover Corrupted Blob Object.

No, you can't undo, rollback or reverse a commit.

STOP THE DATABASE!

(Note: if you deleted the data directory off the filesystem, do NOT stop the database. The following advice applies to an accidental commit of a DELETE or similar, not an rm -rf /data/directory scenario).

If this data was important, STOP YOUR DATABASE NOW and do not restart it. Use pg_ctl stop -m immediate so that no checkpoint is run on shutdown.

You cannot roll back a transaction once it has commited. You will need to restore the data from backups, or use point-in-time recovery, which must have been set up before the accident happened.

If you didn't have any PITR / WAL archiving set up and don't have backups, you're in real trouble.

Urgent mitigation

Once your database is stopped, you should make a file system level copy of the whole data directory - the folder that contains base, pg_clog, etc. Copy all of it to a new location. Do not do anything to the copy in the new location, it is your only hope of recovering your data if you do not have backups. Make another copy on some removable storage if you can, and then unplug that storage from the computer. Remember, you need absolutely every part of the data directory, including pg_xlog etc. No part is unimportant.

Exactly how to make the copy depends on which operating system you're running. Where the data dir is depends on which OS you're running and how you installed PostgreSQL.

Ways some data could've survived

If you stop your DB quickly enough you might have a hope of recovering some data from the tables. That's because PostgreSQL uses multi-version concurrency control (MVCC) to manage concurrent access to its storage. Sometimes it will write new versions of the rows you update to the table, leaving the old ones in place but marked as "deleted". After a while autovaccum comes along and marks the rows as free space, so they can be overwritten by a later INSERT or UPDATE. Thus, the old versions of the UPDATEd rows might still be lying around, present but inaccessible.

Additionally, Pg writes in two phases. First data is written to the write-ahead log (WAL). Only once it's been written to the WAL and hit disk, it's then copied to the "heap" (the main tables), possibly overwriting old data that was there. The WAL content is copied to the main heap by the bgwriter and by periodic checkpoints. By default checkpoints happen every 5 minutes. If you manage to stop the database before a checkpoint has happened and stopped it by hard-killing it, pulling the plug on the machine, or using pg_ctl in immediate mode you might've captured the data from before the checkpoint happened, so your old data is more likely to still be in the heap.

Now that you have made a complete file-system-level copy of the data dir you can start your database back up if you really need to; the data will still be gone, but you've done what you can to give yourself some hope of maybe recovering it. Given the choice I'd probably keep the DB shut down just to be safe.

Recovery

You may now need to hire an expert in PostgreSQL's innards to assist you in a data recovery attempt. Be prepared to pay a professional for their time, possibly quite a bit of time.

I posted about this on the Pg mailing list, and ?????? ?????? linked to depesz's post on pg_dirtyread, which looks like just what you want, though it doesn't recover TOASTed data so it's of limited utility. Give it a try, if you're lucky it might work.

See: pg_dirtyread on GitHub.

I've removed what I'd written in this section as it's obsoleted by that tool.

See also PostgreSQL row storage fundamentals

Prevention

See my blog entry Preventing PostgreSQL database corruption.

On a semi-related side-note, if you were using two phase commit you could ROLLBACK PREPARED for a transction that was prepared for commit but not fully commited. That's about the closest you get to rolling back an already-committed transaction, and does not apply to your situation.

I just installed MySQL 5.7 on Windows7. The database files are located in the following directory which is a hidden one: C:\ProgramData\MySQL\MySQL Server 5.7\Data

The my.ini file is located in the same root: C:\ProgramData\MySQL\MySQL Server 5.7

I´d say MoDisco is by far the most powerful one (though probably not the easiest one to work with).

MoDisco is a generic reverse engineering framework (so that you can customize your reverse engineering project, with MoDisco you can even reverse engineer the behaviour of the java methods, not only the structure and signatures) but also includes some predefined features like the generation of class diagrams out of Java code that you need.

There's an entire practice that says it's a bad idea to have inline functions/styles. Taking into account you already have an ID for your button, consider

JS

var myvar=15;
function init(){
    document.getElementById('EditBanner').onclick=function(){EditBanner(myvar);};
}
window.onload=init;

HTML

<input id="EditBanner" type="button"  value="Edit Image" />

DateTime is an immutable type, so you can't change it.

However, you can create a new DateTime instance based on your previous instance. In your case, it sounds like you need the Date property, and you can then add a TimeSpan that represents the time of day.

Something like this:

var newDt = s.Date + TimeSpan.FromHours(2);

Laravel raw sql – Insert query:

lets create a get link to insert data which is accessible through url . so our link name is ‘insertintodb’ and inside that function we use db class . db class helps us to interact with database . we us db class static function insert . Inside insert function we will write our PDO query to insert data in database . in below query we will insert ‘ my title ‘ and ‘my content’ as data in posts table .

put below code in your web.php file inside routes directory :

Route::get('/insertintodb',function(){
DB::insert('insert into posts(title,content) values (?,?)',['my title','my content']);
});

Now fire above insert query from browser link below :

localhost/yourprojectname/insertintodb

You can see output of above insert query by going into your database table .you will find a record with id 1 .

Laravel raw sql – Read query :

Now , lets create a get link to read data , which is accessible through url . so our link name is ‘readfromdb’. we us db class static function read . Inside read function we will write our PDO query to read data from database . in below query we will read data of id ‘1’ from posts table .

put below code in your web.php file inside routes directory :

Route::get('/readfromdb',function() {
    $result =  DB::select('select * from posts where id = ?', [1]);
    var_dump($result);
});

now fire above read query from browser link below :

localhost/yourprojectname/readfromdb

It's a reserved keyword (like return, filter, function, break).

Reference

Also, as per Section 7.6.4 of Bruce Payette's Powershell in Action:

But what happens when you want a script to exit from within a function defined in that script? ... To make this easier, Powershell has the exit keyword.

Of course, as other have pointed out, it's not hard to do what you want by wrapping exit in a function:

PS C:\> function ex{exit}
PS C:\> new-alias ^D ex

By using git-add with '--all' or '--update' options you may get more than you wanted. New and/or modified files will also be added to the index. I have a bash alias setup for when I want to remove deleted files from git without touching other files:

alias grma='git ls-files --deleted -z | xargs -0 git rm'

All files that have been removed from the file system are added to the index as deleted.

use display:inline-block; instead of float

you can't centre floats, but inline-blocks centre as if they were text, so on the outer overall container of your "row" - you would set text-align: center; then for each image/caption container (it's those which would be inline-block;) you can re-align the text to left if you require

I wasn't happy with any of the suggested time pickers, so I created my own with inspiration from Perifer's and the HTML5 spec:

http://github.com/gregersrygg/jquery.timeInput

You can either use the new html5 attributes for time input (step, min, max), or use an options object:

<input type="time" name="myTime" class="time-mm-hh" min="9:00" max="18:00" step="1800" />
<input type="time" name="myTime2" class="time-mm-hh" />

<script type="text/javascript">
    $("input[name='myTime']").timeInput(); // use default or html5 attributes
    $("input[name='myTime2']").timeInput({min: "6:00", max: "15:00", step: 900}); // 15 min intervals from 6:00 am to 3:00 pm
</script>

Validates input like this:

• Insert ":" if missing
• Not valid time? Replace with blank
• Not a valid time according to step? Round up/down to closest step

The HTML5 spec doesn't allow am/pm or localized time syntax, so it only allowes the format hh:mm. Seconds is allowed according to spec, but I have not implemented it yet.

It's very "alpha", so there might be some bugs. Feel free to send me patches/pull requests. Have manually tested in IE 6&8, FF, Chrome and Opera (Latest stable on Linux for the latter ones).

It just associates a semaphore with every object, and uses that.

I was having exactly the same problem. I looked for two hours what was wrong with no luck until I realize my POST method was private instead of public .

Funny now seeing that error message is kind of generic. Hope it helps!

You don't have to do everything in one line:

case 'SOME_ACTION':
  const newState = { ...state };
  newState.contents = 
    [
      newState.contents[0],
      {title: newState.contnets[1].title, text: action.payload}
    ];
  return newState

I've faced the same issue. Though the mongodb service is not running, the log showed address already in use message.

 $netstat -tulpn | grep :27017 

returns nothing

On further analysis found that the issue was due to lock file. The service is running fine, after deleting the lock file and restarting it.

$grep "dbpath" /etc/mongodb.conf

dbpath =/var/lib/mongodb

$ls /var/lib/mongodb/mongod.lock

$service mongod start

I think the answers here are great, but I would like to add a scenario.

Several times I've wanted to take a certain amount of characters off the front of a string, without worrying about it's length. There are several ways of doing this with RIGHT() and SUBSTRING(), but they all need to know the length of the string which can sometimes slow things down.

I've use the STUFF() function instead:

SET @Result = STUFF(@Result, 1, @LengthToRemove, '')

This replaces the length of unneeded string with an empty string.

I don't know of any direct answer as how to find exactly what process is using the swap space, however, this link may be helpful. Another good one is over here

Also, use a good tool like htop to see which processes are using a lot of memory and how much swap overall is being used.

here are two samples: http://jsfiddle.net/H5q5h/1/

one uses float:left and a wrapper with overflow:hidden. the wrapper ensures the sibling of the wrapper starts below the wrapper.

the 2nd one uses the more recent display:inline-block and wrapper can be disregarded. but this is not generally supported by older browsers so tread lightly on this one. also, any white space between the items will cause an unnecessary "margin-like" white space on the left and right of the item divs.

Please try the following:

<script>
    $(document).ready(function() {      
        $('.carousel').carousel('pause');
    });
</script>

For anyone struggling with this problem in the now (Feb 2020), the following Medium post was crucial to overcoming it for us.

https://medium.com/@ttulka/spring-http-message-converters-customizing-770814eb2b55

In our case, the app uses @EnableWebMvc and would break if removed so, the section on 'The Life without Spring Boot' was critical. Here's what ended up solving this for us. It allows us to still consume and produce JSON and XML as well as format our datetime during serialization to suit the app's needs.

@Configuration
@ComponentScan("com.company.branch")
@EnableWebMvc
public class WebMvcConfig implements WebMvcConfigurer {

@Override
public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
    converters.add(0, new MappingJackson2XmlHttpMessageConverter(
                new Jackson2ObjectMapperBuilder()
                        .defaultUseWrapper(false)
                        .createXmlMapper(true)
                        .simpleDateFormat("yyyy-mm-dd'T'HH:mm:ss'Z'")
                        .build()
        ));
    converters.add(1, new MappingJackson2HttpMessageConverter(
                new Jackson2ObjectMapperBuilder()
                        .build()
        ));
    }
}

try using HttpClient as Sephy said:

public String getHtml(String url) {
    HttpClient vClient = new DefaultHttpClient();
    HttpGet vGet = new HttpGet(url);
    String response = "";    

    try {
        ResponseHandler<String> vHandler = new BasicResponseHandler();
        response = vClient.execute(vGet, vHandler);
    } catch (Exception e) {
        e.printStackTrace();
    }
    return response;
}

Make sure you import MaterialModule as well since you are using md-input which does not belong to FormsModule

You can also delete cookies without using jquery.cookie plugin:

document.cookie = 'NAMEOFYOURCOOKIE' + '=; expires=Thu, 01-Jan-70 00:00:01 GMT;';

You actually just need to fix the swagger url by removing the starting backslash just like this :

c.SwaggerEndpoint("swagger/v1/swagger.json", "MyAPI V1");

instead of :

c.SwaggerEndpoint("/swagger/v1/swagger.json", "MyAPI V1");

// Two different dates
var date1 = new Date(2013, 05, 13); 
var date2 = new Date(2013, 04, 10) ;
// convert both dates in milliseconds and use Math.min function
var minDate = Math.min(date1.valueOf(), date2.valueOf());
// convert minDate to Date
var date = new Date(minDate);

You can do this with pure CSS but you will need to hard code the offset scroll amounts, which may not be ideal should you be changing page content- or should dimensions of your content change on say window resize.

You're likely best placed to use e.g. jQuery, specifically:

$('html, body').stop().animate({
   scrollTop: element.offset().top
}, 1000);

A complete implementation may be:

$('#up, #down').on('click', function(e){
    e.preventDefault();
    var target= $(this).get(0).id == 'up' ? $('#down') : $('#up');
    $('html, body').stop().animate({
       scrollTop: target.offset().top
    }, 1000);
});

Where element is the target element to scroll to and 1000 is the delay in ms before completion.

Demo Fiddle

The benefit being, no matter what changes to your content dimensions, the function will not need to be altered.

On windows you can use Drip.exe to find memory leaks or check if your free mem routine works.

It's really simple, just enter a website URL and you will see the memory consumption of the integrated IE renderer. Then hit refresh, if the memory increases, you found a memory leak somewhere on the webpage. But this is also very useful to see if routines for freeing memory work for IE.

If the API says to use HTTP Basic authentication, then you need to add an Authorization header to your request. I'd alter your code to look like this:

    WebRequest req = WebRequest.Create(@"https://sub.domain.com/api/operations?param=value&param2=value");
    req.Method = "GET";
    req.Headers["Authorization"] = "Basic " + Convert.ToBase64String(Encoding.Default.GetBytes("username:password"));
    //req.Credentials = new NetworkCredential("username", "password");
    HttpWebResponse resp = req.GetResponse() as HttpWebResponse;

Replacing "username" and "password" with the correct values, of course.

This is one of the basic differences not mentioned in previous comments:
Readonly property will work with textbox for and it will not work with EditorFor.

@Html.TextBoxFor(model => model.DateSoldOn, new { @readonly = "readonly" })

Above code works, where as with following you can't make control to readonly.

@Html.EditorFor(model => model.DateSoldOn, new { @readonly = "readonly" })

Douglas Crockford had a remark about how he wished JavaScript contained a loop structure:

loop
{
  ...code...
}

And I don't think Java would be any worse for having a loop structure either.

There's nothing inherently wrong with while(true) loops, but there is a tendency for teachers to discourage them. From the teaching perspective, it's very easy to have students create endless loops and not understand why the loop isn't ever escaped.

But what they rarely mention is that all looping mechanisms can be replicated with while(true) loops.

while( a() )
{
  fn();
}

is the same as

loop
{
  if ( !a() ) break;
  fn();
}

and

do
{
  fn();
} while( a() );

is the same as:

loop
{
  fn();
  if ( !a() ) break;
}

and

for ( a(); b(); c() )
{
  fn();
}

is the same as:

a();
loop
{
  if ( !b() ) break;
  fn();
  c();
}

As long as you can set up your loops in a way that works the construct that you choose to use is unimportant. If it happens to fit in a for loop, use a for loop.

One last part: keep your loops simple. If there's a lot of functionality that needs to happen on every iteration, put it in a function. You can always optimize it after you've got it working.

There is a new way using transforms. Apply this to the element to centre. It nudges down by half the container height and then 'corrects' by half the element height.

position: relative;
top: 50%;
transform: translateY(-50%);
-webkit-transform: translateY(-50%);
-ms-transform: translateY(-50%);

It works most of the time. I did have a problem where a div was in a div in a li. The list item had a height set and the outer divs made up 3 columns (Foundation). The 2nd and 3rd column divs contained images, and they centered just fine with this technique, however the heading in the first column needed a wrapping div with an explicit height set.

Now, does anyone know if the CSS people are working on a way to align stuff, like, easily? Seeing that its 2014 and even some of my friends are regularly using the internet, I wondered if anyone had considered that centering would be a useful styling feature yet. Just us then?

For anyone that searched and pressed on this link, i solved it by simply searching for mysql notifier and stop mysql from running there, Then run mysql in xampp again and it runs. why this works ? iam not expert, but i think it is easy : port was taken already by mysql notifier so had to stop it there and run it here.

SELECT * FROM SysColumns WHERE Name like 'a%'

Will get you a list of columns, you will want to filter more to restrict it to your target table

From there you can construct some ad-hoc sql

It indicates that you do not have a newline (usually '\n', aka CR or CRLF) at the end of file.

That is, simply speaking, the last byte (or bytes if you're on Windows) in the file is not a newline.

The message is displayed because otherwise there is no way to tell the difference between a file where there is a newline at the end and one where is not. Diff has to output a newline anyway, or the result would be harder to read or process automatically.

Note that it is a good style to always put the newline as a last character if it is allowed by the file format. Furthermore, for example, for C and C++ header files it is required by the language standard.

It is as simple as that. You just need to use "value" attributes instead of "defaultValue" or you can keep both if a pre-selected feature is there.

 ....
const [currentValue, setCurrentValue] = useState(2);
<select id = "dropdown" value={currentValue} defaultValue={currentValue}>
     <option value="N/A">N/A</option>
     <option value="1">1</option>
     <option value="2">2</option>
     <option value="3">3</option>
     <option value="4">4</option>
  </select>
.....

setTimeut(()=> {
 setCurrentValue(4);
}, 4000);

In this case, after 4 secs the dropdown will be auto-selected with option 4.

When app is in background as shanegao you can use

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
{
    if ( application.applicationState == UIApplicationStateInactive || application.applicationState == UIApplicationStateBackground  )
    {
         //opened from a push notification when the app was on background
    }
}

But if you want to launch the application and when app is closed and you want to debug your application you can go to Edit Scheme and in left menu select Run and then in launch select Wait for executable to be launched and then you application launch when you click on push notification

Edit Scheme > Run > Wait for executable to be launched

Add this extension method

public static class ForEachAsyncExtension
{
    public static Task ForEachAsync<T>(this IEnumerable<T> source, int dop, Func<T, Task> body)
    {
        return Task.WhenAll(from partition in Partitioner.Create(source).GetPartitions(dop) 
            select Task.Run(async delegate
            {
                using (partition)
                    while (partition.MoveNext())
                        await body(partition.Current).ConfigureAwait(false);
            }));
    }
}

    var buckets = await s3.ListBucketsAsync();

    foreach (var s3Bucket in buckets.Buckets)

            }
        }
    }
}).Wait();

on my C drive I first create a txt file to create a new table. You can use what ever you want in this text file

in this case the text file is called "Bedrijf.txt"

the content:

Print 'START(A) create table'

GO 1

If not EXISTS
(
    SELECT *
    FROM INFORMATION_SCHEMA.TABLES
    WHERE TABLE_NAME = 'Bedrijf'
)
BEGIN
CREATE TABLE [dbo].[Bedrijf] (
[IDBedrijf] [varchar] (38)   NOT NULL ,
[logo] [varbinary] (max) NULL ,
[VolledigeHandelsnaam] [varchar] (100)  NULL 
) ON [PRIMARY]

save it

then I create an other txt file with the name "Bedrijf.bat" and the extension bat. It's content:

OSQL.EXE  -U Username -P Password -S IPaddress -i C:Bedrijf.txt -o C:Bedrijf.out -d myDatabaseName

save it and from explorer double click to execute

The results will be saved in a txt file on your C drive with the name "Bedrijf.out"

it shows

1> 2> 3> START(A) create table

if all goes well

That's it

They are related values, and kept consistent by the property setter/getter methods (and using the fact that frame is a purely synthesized value, not backed by an actual instance variable).

The main equations are:

frame.origin = center - bounds.size / 2

(which is the same as)

center = frame.origin + bounds.size / 2

(and there’s also)

frame.size = bounds.size

That's not code, just equations to express the invariant between the three properties. These equations also assume your view's transform is the identity, which it is by default. If it's not, then bounds and center keep the same meaning, but frame can change. Unless you're doing non-right-angle rotations, the frame will always be the transformed view in terms of the superview's coordinates.

This stuff is all explained in more detail with a useful mini-library here:

Strings with dates are comparable in JavaScript (if they are syntactically the same), e.g.:

'2020-12-01' < '2020-12-02' == true

This means you can use this expression in a custom sort function:

var arr = [{id:1, date:'2020-12-01'}, {id:1, date:'2020-12-15'}, {id:1, date:'2020-12-12'}]

function sortByDate(a, b) {
    if (a.date < b.date) {
        return 1;
    }
    if (a.date > b.date) {
        return -1;
    }
    return 0;
}

const sorted = arr.sort(sortByDate);
console.log(sorted);

You can add comments in Vim's configuration file by either:

" brief descriptiion of command

or:

"" commended command

Taken from here

You can resolve the issue by forcing the collation used in a query to be a particular collation, e.g. SQL_Latin1_General_CP1_CI_AS or DATABASE_DEFAULT. For example:

SELECT MyColumn
FROM FirstTable a
INNER JOIN SecondTable b
ON a.MyID COLLATE SQL_Latin1_General_CP1_CI_AS = 
b.YourID COLLATE SQL_Latin1_General_CP1_CI_AS

In the above query, a.MyID and b.YourID would be columns with a text-based data type. Using COLLATE will force the query to ignore the default collation on the database and instead use the provided collation, in this case SQL_Latin1_General_CP1_CI_AS.

Basically what's going on here is that each database has its own collation which "provides sorting rules, case, and accent sensitivity properties for your data" (from http://technet.microsoft.com/en-us/library/ms143726.aspx) and applies to columns with textual data types, e.g. VARCHAR, CHAR, NVARCHAR, etc. When two databases have differing collations, you cannot compare text columns with an operator like equals (=) without addressing the conflict between the two disparate collations.

MailMessage mm = new MailMessage(txtEmail.Text, txtTo.Text);
mm.Subject = txtSubject.Text;
mm.Body = txtBody.Text;
if (fuAttachment.HasFile)//file upload select or not
{
    string FileName = Path.GetFileName(fuAttachment.PostedFile.FileName);
    mm.Attachments.Add(new Attachment(fuAttachment.PostedFile.InputStream, FileName));
}
mm.IsBodyHtml = false;
SmtpClient smtp = new SmtpClient();
smtp.Host = "smtp.gmail.com";
smtp.EnableSsl = true;
NetworkCredential NetworkCred = new NetworkCredential(txtEmail.Text, txtPassword.Text);
smtp.UseDefaultCredentials = true;
smtp.Credentials = NetworkCred;
smtp.Port = 587;
smtp.Send(mm);
Response.write("Send Mail");

You can do do it. The input type submit should be inside of a form. Then all you have to do is write the link you want to redirect to inside the action attribute that is inside the form tag.

Code To Get Today's date in any specific Format

You can define the desired format in SimpleDateFormat instance to get the date in that specific formate

 DateFormat dateFormat = new SimpleDateFormat("MM/dd/yyyy");
        Calendar cal = Calendar.getInstance();
        Date date = cal.getTime();
        String todaysdate = dateFormat.format(date);
         System.out.println("Today's date : " + todaysdate);

Follow below links to see the valid date format combination.

https://docs.oracle.com/javase/7/docs/api/java/text/SimpleDateFormat.html

CODE : To get x days ahead or Previous from Today's date, To get the past date or Future date.

For Example :

Today date : 11/27/2018

xdayFromTodaysDate = 2 to get date as 11/29/2018

xdayFromTodaysDate = -2 to get date as 11/25/2018

  public String getAniversaryDate(int xdayFromTodaysDate ){

        DateFormat dateFormat = new SimpleDateFormat("MM/dd/yyyy");
        Calendar cal = Calendar.getInstance();
        Date date = cal.getTime();
        cal.setTime(date);
        cal.add(Calendar.DAY_OF_MONTH,xdayFromTodaysDate);
        date = cal.getTime();
        String aniversaryDate = dateFormat.format(date);
        LOGGER.info("Today's date : " + todaysdate);
          return aniversaryDate;

    }

CODE : To get x days ahead or Previous from a Given date

  public String getAniversaryDate(String givendate, int xdayFromTodaysDate ){


        Calendar cal = Calendar.getInstance();
        DateFormat dateFormat = new SimpleDateFormat("MM/dd/yyyy");
        try {
            Date date = dateFormat.parse(givendate);
            cal.setTime(date);
            cal.add(Calendar.DAY_OF_MONTH,xdayFromTodaysDate);
            date = cal.getTime();
            String aniversaryDate = dateFormat.format(date);
            LOGGER.info("aniversaryDate : " + aniversaryDate);
            return aniversaryDate;
        } catch (ParseException e) {
            e.printStackTrace();
            return null;
        }

    }

You can use Armory plugin which makes switching between projects comfortable. The default shortcut for Project List is Alt + A.

By default currently opened projects are displayed at the top of this list (with bold style).

I know this is an old post but try using an extension method:

    public static IEnumerable<DateTime> Range(this DateTime startDate, DateTime endDate)
    {
        return Enumerable.Range(0, (endDate - startDate).Days + 1).Select(d => startDate.AddDays(d));
    }

and use it like this

    var dates = new DateTime(2000, 1, 1).Range(new DateTime(2000, 1, 31));

Feel free to choose your own dates, you don't have to restrict yourself to January 2000.

If you use:

import Math

then that will allow you to use Math's functions, but you must do Math.Calculate, so that is obviously what you don't want.

If you want to import a module's functions without having to prefix them, you must explicitly name them, like:

from Math import Calculate, Add, Subtract

Now, you can reference Calculate, Add, and Subtract just by their names. If you wanted to import ALL functions from Math, do:

from Math import *

However, you should be very careful when doing this with modules whose contents you are unsure of. If you import two modules who contain definitions for the same function name, one function will overwrite the other, with you none the wiser.

I would suggest:

SELECT DAY(EOMONTH(GETDATE()))

try:

dt <- data.table(A = c(1:5), 
                 B= c(11:15))

x <- ncol(dt)

for(i in 1:x) 
{
     dt[[i]] <- as.character(dt[[i]])
}

When I understand this correctly, you replace the default constructor with a parameterized one and therefore have to describe the JSON keys which are used to call the constructor with.

I had the same error message. For me it was happening because I was trying to run the installer from the DVD rather than running the installer from Add/Remove programs.

The problem that you are facing is : TypeError : str returned non-string (type NoneType)

Here you have to understand the str function's working: the str fucntion,although is mostly used to print values but actually is designed to return a string,not to print one. In your class str function is calling the print directly while it is returning nothing ,that explains your error output.Since our formatted string is built, and since our function returns nothing, the None value is used. This was the explaination for your error

You can solve this problem by using the return in str function like: *simply returnig the string value instead of printing it

 class Summary(models.Model):
   book = models.ForeignKey(Book,on_delete = models.CASCADE)
   summary = models.TextField(max_length=600)

    def __str__(self):
        return self.summary

but if the value you are returning in not of string type then you can do like this to return string value from your str function

*typeconverting the value to string that your str function returns

class Summary(models.Model):
   book = models.ForeignKey(Book,on_delete = models.CASCADE)
   summary = models.TextField(max_length=600)

   def __str__(self):
       return str(self.summary)
            `

If you want just a single field, you could use fetchColumn instead of fetch - http://www.php.net/manual/en/pdostatement.fetchcolumn.php

I was looking for a way to get the event type when jQuery listens for several events at once, and Google put me here.

So, for those interested, event.type is my answer :

$('#element').on('keyup keypress blur change', function(event) {
    alert(event.type); // keyup OR keypress OR blur OR change
});

More info in the jQuery doc.

Using DateTime::createFromFormat:

$format = "d_m_y";
$date1  = \DateTime::createFromFormat($format, "03_01_12");
$date2  = \DateTime::createFromFormat($format, "31_12_11");

var_dump($date1 > $date2);

To improve on the answers provided by Alex Kucherenko and Dan Dar3

I added this to my styles:

<style name="Divider">
    <item name="android:layout_width">match_parent</item>
    <item name="android:layout_height">1dp</item>
    <item name="android:background">?android:attr/listDivider</item>
</style>

Then in my layouts is less code and simpler to read.

<View style="@style/Divider"/>

You do not need jQuery for this

In Vanilla you can do :

document.querySelectorAll('.a.b')

you have to be aware that when using interface builder and creating a Xib (nib) containing one cell that there is also a placeholder created that points to the class that will be used. Meaning, when you place two UITableViewCell in one Xib file you possibly run into the exact same trouble causing an *** Assertion failure .... The placeholder mechanism doesn't work adn will be confused then. Instead placing different placeholders in one Xib read on..

The most easy solution (even if that seems a bit to simple) is to place one Cell at a time in one Xib. IB will create a placeholder for you and all works as expected then. But this then leads directly to one extra line of code, because then you need to load the correct nib/xib asking for the reuseIdentified Cell where it resides in. So the following example code focuses the use of multiple Cell Indentifiers in one tableview where an Assertion Failure is very common.

// possibly above class implementation
static NSString *firstCellIdentifier = @"firstCellIdentifier";
static NSString *secondCellIdentifier = @"secondCellIdentifier";

// possibly in -(instancetype)init 
UINib *firstNib = [UINib nibWithNibName:@"FirstCell" bundle:nil];
[self.tableView registerNib:firstNib forCellReuseIdentifier:firstCellIdentifier];
UINib *secondNib = [UINib nibWithNibName:@"SecondCell" bundle:nil];
[self.tableView registerNib:secondNib forCellReuseIdentifier:secondCellIdentifier];

Another trouble with the use of two CellIdentifier's in one UITableView is that row height and/or section height have to be taken care of. Two cells can have different heights of course.

When registering classes for reuse the code should look different.

The "simple solution" looks also much different when your cells reside inside a Storyboard instead of Xib's. Watch out for the placeholders.

Keep also in mind that interface builder files have version wise variations and need to be set to a version that your targeted OS version supports. Even if you may be lucky that the particular feature you placed in your Xib is not changed since the last IB version and does not throw errors yet. So a Xib made with IB set to be compatible to iOS 13+ but used in a target that is compiled on an earlier version iOS 12.4 will cause also trouble and can end up with Assertion failure.

Try the -i flag (or --ignore-errors). The documentation seems to suggest a more robust way to achieve this, by the way:

To ignore errors in a command line, write a - at the beginning of the line's text (after the initial tab). The - is discarded before the command is passed to the shell for execution.

For example,

clean:
  -rm -f *.o

This causes rm to continue even if it is unable to remove a file.

All examples are with rm, but are applicable to any other command you need to ignore errors from (i.e. mkdir).

Might be a very late answer, but this is good and simple.

select * from table_name order by id desc limit 5

This query will return a set of last 5 values(last 5 rows) you 've inserted in your table

I also faced the same problem but I resolved the issue by starting the TNS listener in control panel -> administrative tools -> services ->oracle TNS listener start.I am using windows Xp and Toad to connect to Oracle.

In newer versions of Git for Windows, Bash is started with --login which causes Bash to not read .bashrc directly. Instead it reads .bash_profile.

If this file does not exist, create it with the following content:

if [ -f ~/.bashrc ]; then . ~/.bashrc; fi

This will cause Bash to read the .bashrc file. From my understanding of this issue, Git for Windows should do this automatically. However, I just installed version 2.5.1, and it did not.

Instead of adding any tag which is never a good solution. You can always use margin property with the required element.

You can add the margin on row class itself. So it will affect globally.

.row{
  margin-top: 30px;
  margin-bottom: 30px
}

Update: Better solution in all cases would be to introduce a new class and then use it along with .row class.

.row-m-t{
  margin-top : 20px
}

Then use it wherever you want

<div class="row row-m-t"></div>

Here is how I fixed this issue:

Open the nuget package manager console and install the below nuget packages:

Install-Package WebMatrix.Data
Install-Package Microsoft.AspNet.WebHelpers
Update-Package

Clean the solution, rebuild and my asp.net web app starts working!

You can use bookmarklets if you want run bigger scripts in more convenient way and run them automatically by one click.

Just as normal, using data-original-title:

Html:

<div rel='tooltip' data-original-title='<h1>big tooltip</h1>'>Visible text</div>

Javascript:

$("[rel=tooltip]").tooltip({html:true});

The html parameter specifies how the tooltip text should be turned into DOM elements. By default Html code is escaped in tooltips to prevent XSS attacks. Say you display a username on your site and you show a small bio in a tooltip. If the html code isn't escaped and the user can edit the bio themselves they could inject malicious code.

if you do not intend to have static functions just get rid of the "this" keyword in the arguments.

Here are the timeit results for the top 2 answers. Note that "file.txt" is a text file containing 100,000+ lines of random string with a file size of 1MB+.

Using itertools:

import itertools
from timeit import timeit

timeit("""with open("file.txt", "r") as fo:
    for line in itertools.islice(fo, 90000, None):
        line.strip()""", number=100)

>>> 1.604976346003241

Using two for loops:

from timeit import timeit

timeit("""with open("file.txt", "r") as fo:
    for i in range(90000):
        next(fo)
    for j in fo:
        j.strip()""", number=100)

>>> 2.427317383000627

clearly the itertools method is more efficient when dealing with large files.

So I take it you want 2 options default selected, and then get the value of it? If so:

http://jsfiddle.net/NdQbw/1/

<div class="divright">
    <select id="drp_Books_Ill_Illustrations" class="leaderMultiSelctdropdown Books_Illustrations" name="drp_Books_Ill_Illustrations" multiple="">
        <option value=" ">No illustrations</option>
        <option value="a" selected>Illustrations</option>
        <option value="b">Maps</option>
        <option value="c" selected>selectedPortraits</option>
    </select>
</div>

And to get value:

alert($(".leaderMultiSelctdropdown").val());

To set the value:

 $(".leaderMultiSelctdropdown").val(["a", "c"]);

You can also use an array to set the values:

var selectedValues = new Array();
selectedValues[0] = "a";
selectedValues[1] = "c";

$(".Books_Illustrations").val(selectedValues);

First of all, check out my post on retained Fragments. It might help.

Now to answer your questions:

Does the fragment also retain its view state, or will this be recreated on configuration change - what exactly is "retained"?

Yes, the Fragment's state will be retained across the configuration change. Specifically, "retained" means that the fragment will not be destroyed on configuration changes. That is, the Fragment will be retained even if the configuration change causes the underlying Activity to be destroyed.

Will the fragment be destroyed when the user leaves the activity?

Just like Activitys, Fragments may be destroyed by the system when memory resources are low. Whether you have your fragments retain their instance state across configuration changes will have no effect on whether or not the system will destroy the Fragments once you leave the Activity. If you leave the Activity (i.e. by pressing the home button), the Fragments may or may not be destroyed. If you leave the Activity by pressing the back button (thus, calling finish() and effectively destroying the Activity), all of the Activitys attached Fragments will also be destroyed.

Why doesn't it work with fragments on the back stack?

There are probably multiple reasons why it's not supported, but the most obvious reason to me is that the Activity holds a reference to the FragmentManager, and the FragmentManager manages the backstack. That is, no matter if you choose to retain your Fragments or not, the Activity (and thus the FragmentManager's backstack) will be destroyed on a configuration change. Another reason why it might not work is because things might get tricky if both retained fragments and non-retained fragments were allowed to exist on the same backstack.

Which are the use cases where it makes sense to use this method?

Retained fragments can be quite useful for propagating state information — especially thread management — across activity instances. For example, a fragment can serve as a host for an instance of Thread or AsyncTask, managing its operation. See my blog post on this topic for more information.

In general, I would treat it similarly to using onConfigurationChanged with an Activity... don't use it as a bandaid just because you are too lazy to implement/handle an orientation change correctly. Only use it when you need to.

Probably this is not best code for this task, but is working -

def front_back(a, b):

 if len(a) % 2 == 0 and len(b) % 2 == 0:
    print a[:(len(a)/2)] + b[:(len(b)/2)] + a[(len(a)/2):] + b[(len(b)/2):]

 elif len(a) % 2 == 1 and len(b) % 2 == 0:
    print a[:(len(a)/2)+1] + b[:(len(b)/2)] + a[(len(a)/2)+1:] + b[(len(b)/2):] 

 elif len(a) % 2 == 0 and len(b) % 2 == 1:
     print a[:(len(a)/2)] + b[:(len(b)/2)+1] + a[(len(a)/2):] + b[(len(b)/2)+1:] 

 else :
     print a[:(len(a)/2)+1] + b[:(len(b)/2)+1] + a[(len(a)/2)+1:] + b[(len(b)/2)+1:]

You shouldn´t use client javascript to access databases for several reasons (bad practice, security issues, etc) but if you really want to do this, here is an example:

var connection = new ActiveXObject("ADODB.Connection") ;

var connectionstring="Data Source=<server>;Initial Catalog=<catalog>;User ID=<user>;Password=<password>;Provider=SQLOLEDB";

connection.Open(connectionstring);
var rs = new ActiveXObject("ADODB.Recordset");

rs.Open("SELECT * FROM table", connection);
rs.MoveFirst
while(!rs.eof)
{
   document.write(rs.fields(1));
   rs.movenext;
}

rs.close;
connection.close; 

A better way to connect to a sql server would be to use some server side language like PHP, Java, .NET, among others. Client javascript should be used only for the interfaces.

And there are rumors of an ancient legend about the existence of server javascript, but this is another story. ;)

NOTE:

The mentioned LATEST and RELEASE metaversions have been dropped for plugin dependencies in Maven 3 "for the sake of reproducible builds", over 6 years ago. (They still work perfectly fine for regular dependencies.) For plugin dependencies please refer to this Maven 3 compliant solution.

If you always want to use the newest version, Maven has two keywords you can use as an alternative to version ranges. You should use these options with care as you are no longer in control of the plugins/dependencies you are using.

When you depend on a plugin or a dependency, you can use the a version value of LATEST or RELEASE. LATEST refers to the latest released or snapshot version of a particular artifact, the most recently deployed artifact in a particular repository. RELEASE refers to the last non-snapshot release in the repository. In general, it is not a best practice to design software which depends on a non-specific version of an artifact. If you are developing software, you might want to use RELEASE or LATEST as a convenience so that you don't have to update version numbers when a new release of a third-party library is released. When you release software, you should always make sure that your project depends on specific versions to reduce the chances of your build or your project being affected by a software release not under your control. Use LATEST and RELEASE with caution, if at all.

See the POM Syntax section of the Maven book for more details. Or see this doc on Dependency Version Ranges, where:

• A square bracket ( [ & ] ) means "closed" (inclusive).
• A parenthesis ( ( & ) ) means "open" (exclusive).

Here's an example illustrating the various options. In the Maven repository, com.foo:my-foo has the following metadata:

<?xml version="1.0" encoding="UTF-8"?><metadata>
  <groupId>com.foo</groupId>
  <artifactId>my-foo</artifactId>
  <version>2.0.0</version>
  <versioning>
    <release>1.1.1</release>
    <versions>
      <version>1.0</version>
      <version>1.0.1</version>
      <version>1.1</version>
      <version>1.1.1</version>
      <version>2.0.0</version>
    </versions>
    <lastUpdated>20090722140000</lastUpdated>
  </versioning>
</metadata>

If a dependency on that artifact is required, you have the following options (other version ranges can be specified of course, just showing the relevant ones here):

Declare an exact version (will always resolve to 1.0.1):

<version>[1.0.1]</version>

Declare an explicit version (will always resolve to 1.0.1 unless a collision occurs, when Maven will select a matching version):

<version>1.0.1</version>

Declare a version range for all 1.x (will currently resolve to 1.1.1):

<version>[1.0.0,2.0.0)</version>

Declare an open-ended version range (will resolve to 2.0.0):

<version>[1.0.0,)</version>

Declare the version as LATEST (will resolve to 2.0.0) (removed from maven 3.x)

<version>LATEST</version>

Declare the version as RELEASE (will resolve to 1.1.1) (removed from maven 3.x):

<version>RELEASE</version>

Note that by default your own deployments will update the "latest" entry in the Maven metadata, but to update the "release" entry, you need to activate the "release-profile" from the Maven super POM. You can do this with either "-Prelease-profile" or "-DperformRelease=true"

It's worth emphasising that any approach that allows Maven to pick the dependency versions (LATEST, RELEASE, and version ranges) can leave you open to build time issues, as later versions can have different behaviour (for example the dependency plugin has previously switched a default value from true to false, with confusing results).

It is therefore generally a good idea to define exact versions in releases. As Tim's answer points out, the maven-versions-plugin is a handy tool for updating dependency versions, particularly the versions:use-latest-versions and versions:use-latest-releases goals.

Nothing compares to extjs in terms of community size and presence on StackOverflow. Despite previous controversy, Ext JS now has a GPLv3 open source license. Its learning curve is long, but it can be quite rewarding once learned. Ext JS lacks a Material Design theme, and the team has repeatedly refused to release the source code on GitHub. For mobile, one must use the separate Sencha Touch library.

Have in mind also that,

large JavaScript libraries, such as YUI, have been receiving less attention from the community. Many developers today look at large JavaScript libraries as walled gardens they don’t want to be locked into.

-- Announcement of YUI development being ceased

That said, below are a number of Ext JS alternatives currently available.

Leading client widget libraries

1. Blueprint is a React-based UI toolkit developed by big data analytics company Palantir in TypeScript, and "optimized for building complex data-dense interfaces for desktop applications". Actively developed on GitHub as of May 2019, with comprehensive documentation. Components range from simple (chips, toast, icons) to complex (tree, data table, tag input with autocomplete, date range picker. No accordion or resizer.

   Blueprint targets modern browsers (Chrome, Firefox, Safari, IE 11, and Microsoft Edge) and is licensed under a modified Apache license.

2. Webix - an advanced, easy to learn, mobile-friendly, responsive and rich free&open source JavaScript UI components library. Webix spun off from DHTMLX Touch (a project with 8 years of development behind it - see below) and went on to become a standalone UI components framework. The GPL3 edition allows commercial use and lets non-GPL applications using Webix keep their license, e.g. MIT, via a license exemption for FLOSS. Webix has 55 UI widgets, including trees, grids, treegrids and charts. Funding comes from a commercial edition with some advanced widgets (Pivot, Scheduler, Kanban, org chart etc.). Webix has an extensive list of free and commercial widgets, and integrates with most popular frameworks (React, Vue, Meteor, etc) and UI components.

   

   Skins look modern, and include a Material Design theme. The Touch theme also looks quite Material Design-ish. See also the Skin Builder.

   Minimal GitHub presence, but includes the library code, and the documentation (which still needs major improvements). Webix suffers from a having a small team and a lack of marketing. However, they have been responsive to user feedback, both on GitHub and on their forum.

   The library was lean (128Kb gzip+minified for all 55 widgets as of ~2015), faster than ExtJS, dojo and others, and the design is pleasant-looking. The current version of Webix (v6, as of Nov 2018) got heavier (400 - 676kB minified but NOT gzipped).

   The demos on Webix.com look and function great. The developer, XB Software, uses Webix in solutions they build for paying customers, so there's likely a good, funded future ahead of it.

   Webix aims for backwards compatibility down to IE8, and as a result carries some technical debt.

3. react-md - MIT-licensed Material Design UI components library for React. Responsive, accessible. Implements components from simple (buttons, cards) to complex (sortable tables, autocomplete, tags input, calendars). One lead author, ~1900 GitHub stars.

4. kendo - jQuery-based UI toolkit with 40+ basic open-source widgets, plus commercial professional widgets (grids, trees, charts etc.). Responsive&mobile support. Works with Bootstrap and AngularJS. Modern, with Material Design themes. The documentation is available on GitHub, which has enabled numerous contributions from users (4500+ commits, 500+ PRs as of Jan 2015).

   

   Well-supported commercially, claiming millions of developers, and part of a large family of developer tools. Telerik has received many accolades, is a multi-national company (Bulgaria, US), was acquired by Progress Software, and is a thought leader.

   A Kendo UI Professional developer license costs $700 and posting access to most forums is conditioned upon having a license or being in the trial period.

5. OpenUI5 - jQuery-based UI framework with 180 widgets, Apache 2.0-licensed and fully-open sourced and funded by German software giant SAP SE.

   

   The community is much larger than that of Webix, SAP is hiring developers to grow OpenUI5, and they presented OpenUI5 at OSCON 2014.

   The desktop themes are rather lackluster, but the Fiori design for web and mobile looks clean and neat.

   Wikipedia • GitHub • Mobile-first controls demos • Desktop controls demos • SO

6. DHTMLX - JavaScript library for building rich Web and Mobile apps. Looks most like ExtJS - check the demos. Has been developed since 2005 but still looks modern. All components except TreeGrid are available under GPLv2 but advanced features for many components are only available in the commercial PRO edition - see for example the tree. Claims to be used by many Fortune 500 companies.

   

   Minimal presence on GitHub (the main library code is missing) and StackOverflow but active forum. The documentation is not available on GitHub, which makes it difficult to improve by the community.

7. Polymer, a Web Components polyfill, plus Polymer Paper, Google's implementation of the Material design. Aimed at web and mobile apps. Doesn't have advanced widgets like trees or even grids but the controls it provides are mobile-first and responsive. Used by many big players, e.g. IBM or USA Today.

   

8. Ant Design claims it is "a design language for background applications", influenced by "nature" and helping designers "create low-entropy atmosphere for developer team". That's probably a poor translation from Chinese for "UI components for enterprise web applications". It's a React UI library written in TypeScript, with many components, from simple (buttons, cards) to advanced (autocomplete, calendar, tag input, table).

   The project was born in China, is popular with Chinese companies, and parts of the documentation are available only in Chinese. Quite popular on GitHub, yet it makes the mistake of splitting the community into Chinese and English chat rooms. The design looks Material-ish, but fonts are small and the information looks lost in a see of whitespace.

9. PrimeUI - collection of 45+ rich widgets based on jQuery UI. Apache 2.0 license. Small GitHub community. 35 premium themes available.

10. qooxdoo - "a universal JavaScript framework with a coherent set of individual components", developed and funded by German hosting provider 1&1 (see the contributors, one of the world's largest hosting companies. GPL/EPL (a business-friendly license).

    Mobile themes look modern but desktop themes look old (gradients).

11. jQuery UI - easy to pick up; looks a bit dated; lacks advanced widgets. Of course, you can combine it with independent widgets for particular needs, e.g. trees or other UI components, but the same can be said for any other framework.

12. angular + Angular UI. While Angular is backed by Google, it's being radically revamped in the upcoming 2.0 version, and "users will need to get to grips with a new kind of architecture. It's also been confirmed that there will be no migration path from Angular 1.X to 2.0". Moreover, the consensus seems to be that Angular 2 won't really be ready for use until a year or two from now. Angular UI has relatively few widgets (no trees, for example).

13. DojoToolkit and their powerful Dijit set of widgets. Completely open-sourced and actively developed on GitHub, but development is now (Nov 2018) focused on the new dojo.io framework, which has very few basic widgets. BSD/AFL license. Development started in 2004 and the Dojo Foundation is being sponsored by IBM, Google, and others - see Wikipedia. 7500 questions here on SO.

    

    Themes look desktop-oriented and dated - see the theme tester in dijit. The official theme previewer is broken and only shows "Claro". A Bootstrap theme exists, which looks a lot like Bootstrap, but doesn't use Bootstrap classes. In Jan 2015, I started a thread on building a Material Design theme for Dojo, which got quite popular within the first hours. However, there are questions regarding building that theme for the current Dojo 1.10 vs. the next Dojo 2.0. The response to that thread shows an active and wide community, covering many time zones.

    Unfortunately, Dojo has fallen out of popularity and fewer companies appear to use it, despite having (had?) a strong foothold in the enterprise world. In 2009-2012, its learning curve was steep and the documentation needed improvements; while the documentation has substantially improved, it's unclear how easy it is to pick up Dojo nowadays.

    With a Material Design theme, Dojo (2.0?) might be the killer UI components framework.

14. Enyo - front-end library aimed at mobile and TV apps (e.g. large touch-friendly controls). Developed by LG Electronix and Apache-licensed on GitHub.

15. The radical Cappuccino - Objective-J (a superset of JavaScript) instead of HTML+CSS+DOM

16. Mochaui, MooTools UI Library User Interface Library. <300 GitHub stars.

17. CrossUI - cross-browser JS framework to develop and package the exactly same code and UI into Web Apps, Native Desktop Apps (Windows, OS X, Linux) and Mobile Apps (iOS, Android, Windows Phone, BlackBerry). Open sourced LGPL3. Featured RAD tool (form builder etc.). The UI looks desktop-, not web-oriented. Actively developed, small community. No presence on GitHub.

18. ZinoUI - simple widgets. The DataTable, for instance, doesn't even support sorting.

19. Wijmo - good-looking commercial widgets, with old (jQuery UI) widgets open-sourced on GitHub (their development stopped in 2013). Developed by ComponentOne, a division of GrapeCity. See Wijmo Complete vs. Open.

20. CxJS - commercial JS framework based on React, Babel and webpack offering form elements, form validation, advanced grid control, navigational elements, tooltips, overlays, charts, routing, layout support, themes, culture dependent formatting and more.

Widgets - Demo Apps - Examples - GitHub

Full-stack frameworks

1. SproutCore - developed by Apple for web applications with native performance, handling large data sets on the client. Powers iCloud.com. Not intended for widgets.

2. Wakanda: aimed at business/enterprise web apps - see What is Wakanda?. Architecture:

   • Wakanda Server (server-side JavaScript (custom engine) + open-source NoSQL database)
   • desktop IDE and WYSIWYG editor for tables, forms, reports

   • Wakanda Application Framework (datasource layer + browser-based interface widgets) that helps with browser and device compatibility across desktop and mobile

     Wakanda is highly integrated, includes a ton of features out of the box, but has a very small GitHub community and SO presence.

3. Servoy - "a cross platform frontend development and deployment environment for SQL databases". Boasts a "full WYSIWIG (What You See Is What You Get) UI designer for HTML5 with built-in data-binding to back-end services", responsive design, support for HTML6 Web Components, Websockets and mobile platforms. Written in Java and generates JavaScript code using various JavaBeans.

4. SmartClient/SmartGWT - mobile and cross-browser HTML5 UI components combined with a Java server. Aimed at building powerful business apps - see demos.

5. Vaadin - full-stack Java/GWT + JavaScript/HTML3 web app framework

6. Backbase - portal software

7. Shiny - front-end library on top R, with visualization, layout and control widgets

8. ZKOSS: Java+jQuery+Bootstrap framework for building enterprise web and mobile apps.

CSS libraries + minimal widgets

These libraries don't implement complex widgets such as tables with sorting/filtering, autocompletes, or trees.

1. Bootstrap

2. Foundation for Apps - responsive front-end framework on top of AngularJS; more of a grid/layout/navigation library

3. UI Kit - similar to Bootstrap, with fewer widgets, but with official off-canvas.

Libraries using HTML Canvas

Using the canvas elements allows for complete control over the UI, and great cross-browser compatibility, but comes at the cost of missing native browser functionality, e.g. page search via Ctrl/Cmd+F.

1. Zebra - demos

No longer developed as of Dec 2014

1. Yahoo! User Interface - YUI, launched in 2005, but no longer maintained by the core contributors - see the announcement, which highlights reasons why large UI widget libraries are perceived as walled gardens that developers don't want to be locked into.
2. echo3, GitHub. Supports writing either server-side Java applications that don't require developer knowledge of HTML, HTTP, or JavaScript, or client-side JavaScript-based applications do not require a server, but can communicate with one via AJAX. Last update: July 2013.

If you have bash completion for make installed, the completion script will define a function _make_target_extract_script. This function is meant to create a sed script which can be used to obtain the targets as a list.

Use it like this:

# Make sure bash completion is enabled
source /etc/bash_completion 

# List targets from Makefile
sed -nrf <(_make_target_extract_script --) Makefile

This is my answer which solved the same problem. Fragment2.java is the fragment class which holds the layout of fragment2.xml.

public void onClick(View v) {
                    Fragment  fragment2 = new Fragement2();
                    FragmentManager fragmentManager = getFragmentManager();
                    FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
                    fragmentTransaction.replace(R.id.frame_container, fragment2);
                    fragmentTransaction.addToBackStack(null);
                    fragmentTransaction.commit();   
                }

You can check your all defined function by

$arr = get_defined_functions();
print_r($arr);

this will give you array of all functions in if your function exist in it you can use it like:

 {{ user.myfunction({{parameter}}) }}

Instead of Str(RequestID), try convert(varchar(38), RequestID)

An effective savior for this kind of situation is Time Machine (OS X) or a similar time-based backup system. It's saved me a couple of times because I can go back and restore just that one file.

Edit 2018-02-06: revision based on this comment

Edit: forgot to mention that this works on Python 2.7.x

There's multiprocesing.pool, and the following sample illustrates how to use one of them:

from multiprocessing.pool import ThreadPool as Pool
# from multiprocessing import Pool

pool_size = 5  # your "parallelness"

# define worker function before a Pool is instantiated
def worker(item):
    try:
        api.my_operation(item)
    except:
        print('error with item')

pool = Pool(pool_size)

for item in items:
    pool.apply_async(worker, (item,))

pool.close()
pool.join()

Now if you indeed identify that your process is CPU bound as @abarnert mentioned, change ThreadPool to the process pool implementation (commented under ThreadPool import). You can find more details here: http://docs.python.org/2/library/multiprocessing.html#using-a-pool-of-workers

New style classes may use super(Foo, self) where Foo is a class and self is the instance.

super(type[, object-or-type])

Return a proxy object that delegates method calls to a parent or sibling class of type. This is useful for accessing inherited methods that have been overridden in a class. The search order is same as that used by getattr() except that the type itself is skipped.

And in Python 3.x you can simply use super() inside a class without any parameters.

For Example:

$data = array('firstKey' => 'firstValue', 'secondKey' => 'secondValue');

For changing key value:

$data['firstKey'] = 'changedValue'; 
//this will change value of firstKey because firstkey is available in array

output:

Array ( [firstKey] => changedValue [secondKey] => secondValue )

For adding new key value pair:

$data['newKey'] = 'newValue'; 
//this will add new key and value because newKey is not available in array

output:

Array ( [firstKey] => firstValue [secondKey] => secondValue [newKey] => newValue )

Make sure your iframe is already loaded. Old but reliable way without jQuery:

<iframe src="samedomain.com/page.htm" id="iframe" onload="access()"></iframe>

<script>
function access() {
   var iframe = document.getElementById("iframe");
   var innerDoc = iframe.contentDocument || iframe.contentWindow.document;
   console.log(innerDoc.body);
}
</script>

select u from UserGroup ug inner join ug.user u 
where ug.group_id = :groupId 
order by u.lastname

As a named query:

@NamedQuery(
  name = "User.findByGroupId",
  query =
    "SELECT u FROM UserGroup ug " +
    "INNER JOIN ug.user u WHERE ug.group_id = :groupId ORDER BY u.lastname"
)

Use paths in the HQL statement, from one entity to the other. See the Hibernate documentation on HQL and joins for details.

This answer doesn't necessarily scale but only requires minor adjustments as the list grows. Semantically it might seem a little counter-intuitive since it is two lists, but aside from that it'll look the way you want in any browser ever made.

Change your TableView Style:

self.tableview = [[UITableView alloc] initwithFrame:frame style:UITableViewStyleGrouped];

As per apple documentation for UITableView:

UITableViewStylePlain- A plain table view. Any section headers or footers are displayed as inline separators and float when the table view is scrolled.

UITableViewStyleGrouped- A table view whose sections present distinct groups of rows. The section headers and footers do not float.

Hope this small change will help you ..

For unmanaged types aka value types, structs:

        Marshal.SizeOf(object);

For managed objects the closer i got is an approximation.

        long start_mem = GC.GetTotalMemory(true);

        aclass[] array = new aclass[1000000];
        for (int n = 0; n < 1000000; n++)
            array[n] = new aclass();

        double used_mem_median = (GC.GetTotalMemory(false) - start_mem)/1000000D;

Do not use serialization.A binary formatter adds headers, so you can change your class and load an old serialized file into the modified class.

Also it won't tell you the real size in memory nor will take into account memory alignment.

[Edit] By using BiteConverter.GetBytes(prop-value) recursivelly on every property of your class you would get the contents in bytes, that doesn't count the weight of the class or references but is much closer to reality. I would recommend to use a byte array for data and an unmanaged proxy class to access values using pointer casting if size matters, note that would be non-aligned memory so on old computers is gonna be slow but HUGE datasets on MODERN RAM is gonna be considerably faster, as minimizing the size to read from RAM is gonna be a bigger impact than unaligned.

Add json jar to your classpath

or use java -classpath json.jar ClassName

Trying to compress a PDF I made with 400ppi tiffs, mostly 8-bit, a few 24-bit, with PackBits compression, using tiff2pdf compressed with Zip/Deflate. One problem I had with every one of these methods: none of the above methods preserved the bookmarks TOC that I painstakingly manually created in Acrobat Pro X. Not even the recommended ebook setting for gs. Sure, I could just open a copy of the original with the TOC intact and do a Replace pages but unfortunately, none of these methods did a satisfactory job to begin with. Either they reduced the size so much that the quality was unacceptably pixellated, or they didn't reduce the size at all and in one case actually increased it despite quality loss.

If you are using Entity Framework 5 < you can use DbGeography. Example from MSDN:

public class University  
{ 
    public int UniversityID { get; set; } 
    public string Name { get; set; } 
    public DbGeography Location { get; set; } 
}

public partial class UniversityContext : DbContext 
{ 
    public DbSet<University> Universities { get; set; } 
}

using (var context = new UniversityContext ()) 
{ 
    context.Universities.Add(new University() 
        { 
            Name = "Graphic Design Institute", 
            Location = DbGeography.FromText("POINT(-122.336106 47.605049)"), 
        }); 

    context. Universities.Add(new University() 
        { 
            Name = "School of Fine Art", 
            Location = DbGeography.FromText("POINT(-122.335197 47.646711)"), 
        }); 

    context.SaveChanges(); 

    var myLocation = DbGeography.FromText("POINT(-122.296623 47.640405)"); 

    var university = (from u in context.Universities 
                        orderby u.Location.Distance(myLocation) 
                        select u).FirstOrDefault(); 

    Console.WriteLine( 
        "The closest University to you is: {0}.", 
        university.Name); 
}

https://msdn.microsoft.com/en-us/library/hh859721(v=vs.113).aspx

Something I struggled with then I started using DbGeography was the coordinateSystemId. See the answer below for an excellent explanation and source for the code below.

public class GeoHelper
{
    public const int SridGoogleMaps = 4326;
    public const int SridCustomMap = 3857;

    public static DbGeography FromLatLng(double lat, double lng)
    {
        return DbGeography.PointFromText(
            "POINT("
            + lng.ToString() + " "
            + lat.ToString() + ")",
            SridGoogleMaps);
    }
}

1. There is no such thing as xhr.file = file;; the file object is not supposed to be attached this way.

2. xhr.send(file) doesn't send the file. You have to use the FormData object to wrap the file into a multipart/form-data post data object:

   var formData = new FormData();
   formData.append("thefile", file);
   xhr.send(formData);
   

After that, the file can be access in $_FILES['thefile'] (if you are using PHP).

Remember, MDC and Mozilla Hack demos are your best friends.

EDIT: The (2) above was incorrect. It does send the file, but it would send it as raw post data. That means you would have to parse it yourself on the server (and it's often not possible, depend on server configuration). Read how to get raw post data in PHP here.

About promise composition vs. Rxjs, as this is a frequently asked question, you can refer to a number of previously asked questions on SO, among which :

• How to do the chain sequence in rxjs
• RxJS Promise Composition (passing data)
• RxJS sequence equvalent to promise.then()?

Basically, flatMap is the equivalent of Promise.then.

For your second question, do you want to replay values already emitted, or do you want to process new values as they arrive? In the first case, check the publishReplay operator. In the second case, standard subscription is enough. However you might need to be aware of the cold. vs. hot dichotomy depending on your source (cf. Hot and Cold observables : are there 'hot' and 'cold' operators? for an illustrated explanation of the concept)

As Arnaud suggested in a comment to the original post, you should put this in your html header:

<meta http-equiv="X-UA-Compatible" content="IE=edge">

I don't want any cred for this. I just want to make it more visible for anyone else that come here.

I like the solution provided by RoToRa (try to parse given value, if it has any boolean meaning, otherwise - don't). Nevertheless I'd like to provide small modification, to have it working more or less like Boolean.TryParse in C#, which supports out params. In JavaScript it can be implemented in the following manner:

var BoolHelpers = {
    tryParse: function (value) {
        if (typeof value == 'boolean' || value instanceof Boolean)
            return value;
        if (typeof value == 'string' || value instanceof String) {
            value = value.trim().toLowerCase();
            if (value === 'true' || value === 'false')
                return value === 'true';
        }
        return { error: true, msg: 'Parsing error. Given value has no boolean meaning.' }
    }
}

The usage:

var result = BoolHelpers.tryParse("false");
if (result.error) alert(result.msg);

Create black png with lets say 50% transparency. Overlay this on mouseover.

You're referencing a DOM element when doing something like $('#lastName'). That's an element with id attribute "lastName". Why do that? You want to reference the value stored in a local variable, completely unrelated. Try this (assuming the assignment to formObject is in the same scope as the variable declarations) -

var formObject = {
    formObject: [
        {
            firstName:firstName,  // no need to quote variable names
            lastName:lastName
        },
        {
            phoneNumber:phoneNumber,
            address:address
        }
    ]
};

This seems very odd though: you're creating an object "formObject" that contains a member called "formObject" that contains an array of objects.

As far as I know, a forced update like this is not directly possible. You might be able to reduce the DNS downtime by reducing the TTL (Time-To-Live) value of the entries before changing them, if your name server service provider allows that.

Here's a guide for less painful DNS changes.

A fair warning, though - not all name servers between your client and the authoritative (origin) name server will enforce your TTL, they might have their own caching time.

Use the find and replace command accessible through ctrl+h, make sure you are searching through the functions of the cells. You can then wildcards to accommodate any deviations of the formula. * for # wildcards, ? for charcter wildcards, and ~? or ~* to search for ? or *.

This is simple and works pretty well:

function twoDigit(number) {
  var twodigit = number >= 10 ? number : "0"+number.toString();
  return twodigit;
}

Isn't the 'date' command much simpler? No need for awk, stat, etc.

date -r <filename>

Also, consider looking at the man page for date formatting; for example with common date and time format:

date -r <filename> "+%m-%d-%Y %H:%M:%S"

References are "hidden pointers" (non-null) to things which can change (lvalues). You cannot define them to a constant. It should be a "variable" thing.

EDIT::

I am thinking of

int &x = y;

as almost equivalent of

int* __px = &y;
#define x (*__px)

where __px is a fresh name, and the #define x works only inside the block containing the declaration of x reference.

There's no mystery here, the linker is telling you that you haven't defined the missing symbols, and you haven't.

Similarity::Similarity() or Similarity::~Similarity() are just missing and you have defined the others incorrectly,

void Similarity::readData(Scanner& inStream){
}

not

void readData(Scanner& inStream){
}

etc. etc.

The second one is a function called readData, only the first is the readData method of the Similarity class.

To be clear about this, in Similarity.h

void readData(Scanner& inStream);

but in Similarity.cpp

void Similarity::readData(Scanner& inStream){
}

The second loop involves a lot less cache activity, so it's easier for the processor to keep up with the memory demands.

If you by writing "non letters and numbers" exclude more than [A-Za-z0-9] (ie. considering letters like åäö to be letters to) and want to be able to accurately handle UTF-8 strings \p{L} and \p{N} will be of aid.

1. \p{N} will match any "Number"
2. \p{L} will match any "Letter Character", which includes
   • Lower case letter
   • Modifier letter
   • Other letter
   • Title case letter
   • Upper case letter

Documentation PHP: Unicode Character Properties

$data = "Thäre!wouldn't%bé#äny";

$new_data = str_replace  ("'", "", $data);
$new_data = preg_replace ('/[^\p{L}\p{N}]/u', '_', $new_data);

var_dump (
  $new_data
);

output

string(23) "Thäre_wouldnt_bé_äny"

Here is a simpler method (hack) that gives you back the setdefaultencoding() function that was deleted from sys:

import sys
# sys.setdefaultencoding() does not exist, here!
reload(sys)  # Reload does the trick!
sys.setdefaultencoding('UTF8')

(Note for Python 3.4+: reload() is in the importlib library.)

This is not a safe thing to do, though: this is obviously a hack, since sys.setdefaultencoding() is purposely removed from sys when Python starts. Reenabling it and changing the default encoding can break code that relies on ASCII being the default (this code can be third-party, which would generally make fixing it impossible or dangerous).

Another option is to use Promise.all to wait for an array of promises to resolve and then act on those.

Code below shows how to wait for all the promises to resolve and then deal with the results once they are all ready (as that seemed to be the objective of the question); Also for illustrative purposes, it shows output during execution (end finishes before middle).

function append_output(suffix, value) {
  $("#output_"+suffix).append(value)
}

function kickOff() {
  let start = new Promise((resolve, reject) => {
    append_output("now", "start")
    resolve("start")
  })
  let middle = new Promise((resolve, reject) => {
    setTimeout(() => {
      append_output("now", " middle")
      resolve(" middle")
    }, 1000)
  })
  let end = new Promise((resolve, reject) => {
    append_output("now", " end")
    resolve(" end")
  })

  Promise.all([start, middle, end]).then(results => {
    results.forEach(
      result => append_output("later", result))
  })
}

kickOff()

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
Updated during execution: <div id="output_now"></div>
Updated after all have completed: <div id="output_later"></div>

Im not sure If this will help anyone but I was getting this error (although I was using php to create it instead of the command line) and to fix it I had to ensure that no old .key or .pem files were in the directory I was looking at. By deleting them and making fresh files with the authentication it worked perfectly!

If use generic repository

> lstModule = _ModuleRepository.GetAll().OrderBy(x => new { x.Level,
> x.Rank}).ToList();

else

> _db.Module.Where(x=> ......).OrderBy(x => new { x.Level, x.Rank}).ToList();

all numbers are stored in binary. if you want a textual representation of a given number in binary, use bin(i)

>>> bin(10)
'0b1010'
>>> 0b1010
10

in the directory that you want to donwload:

git init
git remote add origin -f repoUrl // folder url
touch .git/info/sparse-checkout
git pull origin master

only 4 lines of code

You can use following command -

LENGTH(TRIM(TRANSLATE(string1, '+-.0123456789', '')))

This will return NULL if your string1 is Numeric

your query would be -

select * from tablename 
where LENGTH(TRIM(TRANSLATE(X, '+-.0123456789', ''))) is null

You can do this with one line of code:

Arrays.toString(strings).replaceAll("[\\[.\\].\\s+]", "");

You should look at the article C++ Programming/Type Casting.

It contains a good description of all of the different cast types. The following taken from the above link:

const_cast

const_cast(expression) The const_cast<>() is used to add/remove const(ness) (or volatile-ness) of a variable.

static_cast

static_cast(expression) The static_cast<>() is used to cast between the integer types. 'e.g.' char->long, int->short etc.

Static cast is also used to cast pointers to related types, for example casting void* to the appropriate type.

dynamic_cast

Dynamic cast is used to convert pointers and references at run-time, generally for the purpose of casting a pointer or reference up or down an inheritance chain (inheritance hierarchy).

dynamic_cast(expression)

The target type must be a pointer or reference type, and the expression must evaluate to a pointer or reference. Dynamic cast works only when the type of object to which the expression refers is compatible with the target type and the base class has at least one virtual member function. If not, and the type of expression being cast is a pointer, NULL is returned, if a dynamic cast on a reference fails, a bad_cast exception is thrown. When it doesn't fail, dynamic cast returns a pointer or reference of the target type to the object to which expression referred.

reinterpret_cast

Reinterpret cast simply casts one type bitwise to another. Any pointer or integral type can be casted to any other with reinterpret cast, easily allowing for misuse. For instance, with reinterpret cast one might, unsafely, cast an integer pointer to a string pointer.

I was looking at Swagger Editor and thought it could export the preview pane but turned out it cannot. So I wrote my own version of it.

In case someone need to handle a dynamic object come from Json, I has modified Seth Reno answer to handle dynamic object deserialized from NewtonSoft.Json.JObjcet.

public static bool PropertyExists(dynamic obj, string name)
    {
        if (obj == null) return false;
        if (obj is ExpandoObject)
            return ((IDictionary<string, object>)obj).ContainsKey(name);
        if (obj is IDictionary<string, object> dict1)
            return dict1.ContainsKey(name);
        if (obj is IDictionary<string, JToken> dict2)
            return dict2.ContainsKey(name);
        return obj.GetType().GetProperty(name) != null;
    }

Like mentioned earlier, I'd recommend boost lexical_cast. Not only does it have a fairly nice syntax:

#include <boost/lexical_cast.hpp>
std::string s = boost::lexical_cast<std::string>(i);

it also provides some safety:

try{
  std::string s = boost::lexical_cast<std::string>(i);
}catch(boost::bad_lexical_cast &){
 ...
}

You used the singular in your question but there are typically several authoritative name servers, the RFC 1034 recommends at least two.

Unless you mean "primary name server" and not "authoritative name server". The secondary name servers are authoritative.

To find out the name servers of a domain on Unix:

  % dig +short NS stackoverflow.com
 ns52.domaincontrol.com.
 ns51.domaincontrol.com.

To find out the server listed as primary (the notion of "primary" is quite fuzzy these days and typically has no good answer):

% dig +short  SOA stackoverflow.com | cut -d' ' -f1
ns51.domaincontrol.com.

To check discrepencies between name servers, my preference goes to the old check_soa tool, described in Liu & Albitz "DNS & BIND" book (O'Reilly editor). The source code is available in http://examples.oreilly.com/dns5/

% check_soa stackoverflow.com
ns51.domaincontrol.com has serial number 2008041300
ns52.domaincontrol.com has serial number 2008041300

Here, the two authoritative name servers have the same serial number. Good.

Use:

1..10 | % { write "loop $_" }

Output:

PS D:\temp> 1..10 | % { write "loop $_" }
loop 1
loop 2
loop 3
loop 4
loop 5
loop 6
loop 7
loop 8
loop 9
loop 10

Kind of a mix:

Set it in your layout file :-

 <CheckBox android:layout_width="wrap_content"
           android:layout_height="wrap_content" 
           android:text="new checkbox"
           android:background="@drawable/checkbox_background" 
           android:button="@drawable/checkbox" />

where the @drawable/checkbox will look like:

<?xml version="1.0" encoding="utf-8"?>

<selector xmlns:android="http://schemas.android.com/apk/res/android">
 <item android:state_checked="true" android:state_focused="true"
  android:drawable="@drawable/checkbox_on_background_focus_yellow" />
 <item android:state_checked="false" android:state_focused="true"
  android:drawable="@drawable/checkbox_off_background_focus_yellow" />
 <item android:state_checked="false"
  android:drawable="@drawable/checkbox_off_background" />
 <item android:state_checked="true"
  android:drawable="@drawable/checkbox_on_background" />
</selector>

action:@selector(switchToNewsDetails:)

You do not pass parameters to switchToNewsDetails: method here. You just create a selector to make button able to call it when certain action occurs (touch up in your case). Controls can use 3 types of selectors to respond to actions, all of them have predefined meaning of their parameters:

1. with no parameters

   action:@selector(switchToNewsDetails)
   

2. with 1 parameter indicating the control that sends the message

   action:@selector(switchToNewsDetails:)
   

3. With 2 parameters indicating the control that sends the message and the event that triggered the message:

   action:@selector(switchToNewsDetails:event:)
   

It is not clear what exactly you try to do, but considering you want to assign a specific details index to each button you can do the following:

1. set a tag property to each button equal to required index

2. in switchToNewsDetails: method you can obtain that index and open appropriate deatails:

   - (void)switchToNewsDetails:(UIButton*)sender{
       [self openDetails:sender.tag];
       // Or place opening logic right here
   }
   

In the GSM specification 3GPP TS 11.11, there are 10 bytes set aside in the MSISDN EF (6F40) for 'dialing number'. Since this is the GSM representation of a phone number, and it's usage is nibble swapped, (and there is always the possibility of parentheses) 22 characters of data should be plenty.

In my experience, there is only one instance of open/close parentheses, that is my reasoning for the above.

The problem is that '_' underscores are not valid in header attribute. If removing the underscore is not an option you can add to the server block:

underscores_in_headers on;

This is basically a copy and paste from @kishorer747 comment on @Fleshgrinder answer, and solution is from: https://serverfault.com/questions/586970/nginx-is-not-forwarding-a-header-value-when-using-proxy-pass/586997#586997

I added it here as in my case the application behind nginx was working perfectly fine, but as soon ngix was between my flask app and the client, my flask app would not see the headers any longer. It was kind of time consuming to debug.

Note: This may be obsolete for current versions of Amazon Linux 2 since late 2018 (see comments), you can now directly install it via yum install python3.

In Amazon Linux 2, there isn't a python3[4-6] in the default yum repos, instead there's the Amazon Extras Library.

sudo amazon-linux-extras install python3

If you want to set up isolated virtual environments with it; using yum install'd virtualenv tools don't seem to reliably work.

virtualenv --python=python3 my_venv

Calling the venv module/tool is less finicky, and you could double check it's what you want/expect with python3 --version beforehand.

python3 -m venv my_venv

String value = "{first_name = naresh,last_name = kumar,gender = male}"

Let's start

1. Remove { and } from the String>>first_name = naresh,last_name = kumar,gender = male
2. Split the String from ,>> array of 3 element
3. Now you have an array with 3 element
4. Iterate the array and split each element by =
5. Create a Map<String,String> put each part separated by =. first part as Key and second part as Value

With Flexbox you can easily horizontally (and vertically) center floated children inside a div.

So if you have simple markup like so:

<div class="wpr">
    <span></span>
    <span></span>
    <span></span>
    <span></span>
    <span></span>
</div>

with CSS:

.wpr
{
    width: 400px;
    height: 100px;
    background: pink;
    padding: 10px 30px;
}

.wpr span
{
    width: 50px;
    height: 50px;
    background: green;
    float: left; /* **children floated left** */
    margin: 0 5px;
}

(This is the (expected - and undesirable) RESULT)

Now add the following rules to the wrapper:

display: flex;
justify-content: center; /* align horizontal */

and the floated children get aligned center (DEMO)

Just for fun, to get vertical alignment as well just add:

align-items: center; /* align vertical */

If you are still having issues, try running these steps from VMware to disable credential guard. Worked for me, finally. Steps and link are posted below, not taking credit for them.

Original content from https://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2146361

To disable Device Guard or Credential Guard on Itanium based computers:

1. Disable the group policy setting that was used to enable Credential Guard.

   On the host operating system, click Start > Run, type gpedit.msc, and click Ok. The Local group Policy Editor opens.

   Go to Local Computer Policy > Computer Configuration > Administrative Templates > System > Device Guard > Turn on Virtualization Based Security.

   Select Disabled.

2. Go to Control Panel > Programs and Features > Turn Windows features on or off to turn off Hyper-V. [ remove a program on Windows 8 or earlier]

3. Select Do not restart.

4. Delete the related EFI variables by launching a command prompt on the host machine using an Administrator account and run these commands:

   enter code here

   mountvol X: /s

   copy %WINDIR%\System32\SecConfig.efi X:\EFI\Microsoft\Boot\SecConfig.efi /Y

   bcdedit /create {0cb3b571-2f2e-4343-a879-d86a476d7215} /d "DebugTool" /application osloader

   bcdedit /set {0cb3b571-2f2e-4343-a879-d86a476d7215} path "\EFI\Microsoft\Boot\SecConfig.efi"

   bcdedit /set {bootmgr} bootsequence {0cb3b571-2f2e-4343-a879-d86a476d7215}

   bcdedit /set {0cb3b571-2f2e-4343-a879-d86a476d7215} loadoptions DISABLE-LSA-ISO,DISABLE-VBS

   bcdedit /set {0cb3b571-2f2e-4343-a879-d86a476d7215} device partition=X:

   mountvol X: /d

Note: Ensure X is an unused drive, else change to another drive.

5. Restart the host.

6. Accept the prompt on the boot screen to disable Device Guard or Credential Guard.

You should be able to install and start HAXM now

This is an old question but I just had the same issue (with PHP7) and the solution was, in the end, pretty simple. Uncommenting the line in php.ini as per the other answers wasn't quite enough though. I needed to change it from:

;extension=php_openssl.dll

to:

extension=ext/php_openssl.dll

Note the ext prefix. The dll already existed but was in a subfolder. After changing the config the composer installer was happy.

Interesting I never spent too much time adjusting the colours in IntelliJ although tried once.

See link below with an already defined colour scheme you can import.

Where can I download IntelliJ IDEA 10 Color Schemes?

http://devnet.jetbrains.net/docs/DOC-1154

Download the jar file, file import the jar where you will see a what to import ;)

autowidth: true

worked perfectly for me. learnt from here.

How about this?

if (element.hasClass("class1 class2")

The files selected are stored in an array: [input].files

For example, you can access the items

// assuming there is a file input with the ID `my-input`...
var files = document.getElementById("my-input").files;

for (var i = 0; i < files.length; i++)
{
 alert(files[i].name);
}

For jQuery-comfortable people, it's similarly easy

// assuming there is a file input with the ID `my-input`...
var files = $("#my-input")[0].files;

for (var i = 0; i < files.length; i++)
{
 alert(files[i].name);
}

I used runas /user:domainuser@domain cmd which opened an elevated prompt successfully.

Well in my case the following work fine

<div class="card-body p-2">
  <div class="d-flex flex-row justify-content-center">
     <div style="margin: auto;">
        <input type="text" autocomplete="off"
          style="max-width:150px!important; "
          class="form-control form-control-sm font-weight-bold align-self-center w-25" id="dtTechState">
     </div>
  </div>
</div>

You can only use await in an async method, and Main cannot be async.

You'll have to use your own async-compatible context, call Wait on the returned Task in the Main method, or just ignore the returned Task and just block on the call to Read. Note that Wait will wrap any exceptions in an AggregateException.

If you want a good intro, see my async/await intro post.

Sharepoint Lists automatically have an column with "ID" which auto increments. You simply need to select this column from the "modify view" screen to view it.

Yes, Just be careful if you are also iterating over the list, because in this case you will need to synchronize on it. From the Javadoc:

It is imperative that the user manually synchronize on the returned list when iterating over it:

List list = Collections.synchronizedList(new ArrayList());
    ...
synchronized (list) {
    Iterator i = list.iterator(); // Must be in synchronized block
    while (i.hasNext())
        foo(i.next());
}

Or, you can use CopyOnWriteArrayList which is slower for writes but doesn't have this issue.

There is an extension to the gcc compiler which allows the syntax:

int array[100] = { [0 ... 99] = -1 };

This would set all of the elements to -1.

This is known as "Designated Initializers" see here for further information.

Note this isn't implemented for the gcc c++ compiler.

This question is old, the other answers are old. "Employed Russian"s answer is very good and informative, but it only works if you have the source code. If you don't, the alternatives back then were very tricky. Fortunately nowadays we have a simple solution to this problem (as commented in one of his replies), using patchelf. All you have to do is:

$ ./patchelf --set-interpreter /path/to/newglibc/ld-linux.so.2 --set-rpath /path/to/newglibc/ myapp

And after that, you can just execute your file:

$ ./myapp

No need to chroot or manually edit binaries, thankfully. But remember to backup your binary before patching it, if you're not sure what you're doing, because it modifies your binary file. After you patch it, you can't restore the old path to interpreter/rpath. If it doesn't work, you'll have to keep patching it until you find the path that will actually work... Well, it doesn't have to be a trial-and-error process. For example, in OP's example, he needed GLIBC_2.3, so you can easily find which lib provides that version using strings:

$ strings /lib/i686/libc.so.6 | grep GLIBC_2.3
$ strings /path/to/newglib/libc.so.6 | grep GLIBC_2.3

In theory, the first grep would come empty because the system libc doesn't have the version he wants, and the 2nd one should output GLIBC_2.3 because it has the version myapp is using, so we know we can patchelf our binary using that path. If you get a segmentation fault, read the note at the end.

When you try to run a binary in linux, the binary tries to load the linker, then the libraries, and they should all be in the path and/or in the right place. If your problem is with the linker and you want to find out which path your binary is looking for, you can find out with this command:

$ readelf -l myapp | grep interpreter
  [Requesting program interpreter: /lib/ld-linux.so.2]                                                                                                                                                                                   

If your problem is with the libs, commands that will give you the libs being used are:

$ readelf -d myapp | grep Shared
$ ldd myapp 

This will list the libs that your binary needs, but you probably already know the problematic ones, since they are already yielding errors as in OP's case.

"patchelf" works for many different problems that you may encounter while trying to run a program, related to these 2 problems. For example, if you get: ELF file OS ABI invalid, it may be fixed by setting a new loader (the --set-interpreter part of the command) as I explain here. Another example is for the problem of getting No such file or directory when you run a file that is there and executable, as exemplified here. In that particular case, OP was missing a link to the loader, but maybe in your case you don't have root access and can't create the link. Setting a new interpreter would solve your problem.

Thanks Employed Russian and Michael Pankov for the insight and solution!

Note for segmentation fault: you might be in the case where myapp uses several libs, and most of them are ok but some are not; then you patchelf it to a new dir, and you get segmentation fault. When you patchelf your binary, you change the path of several libs, even if some were originally in a different path. Take a look at my example below:

$ ldd myapp
./myapp: /usr/lib/x86_64-linux-gnu/libstdc++.so.6: version `GLIBCXX_3.4.20' not found (required by ./myapp)
./myapp: /usr/lib/x86_64-linux-gnu/libstdc++.so.6: version `GLIBCXX_3.4.21' not found (required by ./myapp)
        linux-vdso.so.1 =>  (0x00007fffb167c000)
        libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007f9a9aad2000)
        libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007f9a9a8ce000)
        libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007f9a9a6af000)
        libstdc++.so.6 => /usr/lib/x86_64-linux-gnu/libstdc++.so.6 (0x00007f9a9a3ab000)
        libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f9a99fe6000)
        /lib64/ld-linux-x86-64.so.2 (0x00007f9a9adeb000)
        libgcc_s.so.1 => /lib/x86_64-linux-gnu/libgcc_s.so.1 (0x00007f9a99dcf000)

Note that most libs are in /lib/x86_64-linux-gnu/ but the problematic one (libstdc++.so.6) is on /usr/lib/x86_64-linux-gnu. After I patchelf'ed myapp to point to /path/to/mylibs, I got segmentation fault. For some reason, the libs are not totally compatible with the binary. Since myapp didn't complain about the original libs, I copied them from /lib/x86_64-linux-gnu/ to /path/to/mylibs2, and I also copied libstdc++.so.6 from /path/to/mylibs there. Then I patchelf'ed it to /path/to/mylibs2, and myapp works now. If your binary uses different libs, and you have different versions, it might happen that you can't fix your situation. :( But if it's possible, mixing libs might be the way. It's not ideal, but maybe it will work. Good luck!

My simple, simple, simple approach! =D

Code

string_to_test = "The criminals stole $1,000,000 in jewels."
chars_to_check = ["$", ",", "0", "1", "2", "3", "4", "5", "6", "7", "8", "9"]
for char in chars_to_check:
    if char in string_to_test:
        print("Char \"" + char + "\" detected!")

Output

Char "$" detected!
Char "," detected!
Char "0" detected!
Char "1" detected!

Thanks!

Convert the collection into an array by using function

Object[] toArray(Object[] a) 

(This info is from The Git User's Manual)

I'm also learning, so this might not be exactly an answer to the question but it might help somebody:

1. When a remote repository is initially cloned copies of all branches are stored in your local repository (view them with git branch -r)
2. To update these copies and make them current (i.e. sync them with the remote branch) use git fetch. This will not effect any of you existing, custom created branches.
3. To override your local branch checkout a fresh version of whatever branch you are working on (Assuming that you have already executed git add origin /path/to/repository) use git checkout origin/branch_name, this will override your locals changes on branch branch_name

Change

private void Form1_Load(object sender, EventArgs e) 
    { 
        CERas.CERAS = new CERas.CERAS(); 
    } 

to

private void Form1_Load(object sender, EventArgs e) 
    { 
        CERas.CERAS c = new CERas.CERAS(); 
    } 

Or if you wish to use it later again

change it to

using System.Drawing; 
using System.Linq; 
using System.Text; 
using System.Windows.Forms; 

namespace WinApp_WMI2 
{ 
    public partial class Form1 : Form 
    { 
        CERas.CERAS m_CERAS;

        public Form1() 
        { 
            InitializeComponent(); 
        } 

    private void Form1_Load(object sender, EventArgs e) 
    { 
        m_CERAS = new CERas.CERAS(); 
    } 
} 


}

In my case ,first i've meet a '???' in my website, then i check Mysql's character set which is latin now ,so i change it into utf-8,then i restart my project ,then i got the same error with you , then i found that i forget to change the database's charset and change into utf-8, boom,it worked.

menu -> build -> Rebuild Project

has worked for me

As @Felix Kling suggested use action='store_true':

>>> from argparse import ArgumentParser
>>> p = ArgumentParser()
>>> _ = p.add_argument('-f', '--foo', action='store_true')
>>> args = p.parse_args()
>>> args.foo
False
>>> args = p.parse_args(['-f'])
>>> args.foo
True

You could have the function take a variable as the first arg and modify the variable with the string you want to return.

#!/bin/bash
set -x
function pass_back_a_string() {
    eval "$1='foo bar rab oof'"
}

return_var=''
pass_back_a_string return_var
echo $return_var

Prints "foo bar rab oof".

Edit: added quoting in the appropriate place to allow whitespace in string to address @Luca Borrione's comment.

Edit: As a demonstration, see the following program. This is a general-purpose solution: it even allows you to receive a string into a local variable.

#!/bin/bash
set -x
function pass_back_a_string() {
    eval "$1='foo bar rab oof'"
}

return_var=''
pass_back_a_string return_var
echo $return_var

function call_a_string_func() {
     local lvar=''
     pass_back_a_string lvar
     echo "lvar='$lvar' locally"
}

call_a_string_func
echo "lvar='$lvar' globally"

This prints:

+ return_var=
+ pass_back_a_string return_var
+ eval 'return_var='\''foo bar rab oof'\'''
++ return_var='foo bar rab oof'
+ echo foo bar rab oof
foo bar rab oof
+ call_a_string_func
+ local lvar=
+ pass_back_a_string lvar
+ eval 'lvar='\''foo bar rab oof'\'''
++ lvar='foo bar rab oof'
+ echo 'lvar='\''foo bar rab oof'\'' locally'
lvar='foo bar rab oof' locally
+ echo 'lvar='\'''\'' globally'
lvar='' globally

Edit: demonstrating that the original variable's value is available in the function, as was incorrectly criticized by @Xichen Li in a comment.

#!/bin/bash
set -x
function pass_back_a_string() {
    eval "echo in pass_back_a_string, original $1 is \$$1"
    eval "$1='foo bar rab oof'"
}

return_var='original return_var'
pass_back_a_string return_var
echo $return_var

function call_a_string_func() {
     local lvar='original lvar'
     pass_back_a_string lvar
     echo "lvar='$lvar' locally"
}

call_a_string_func
echo "lvar='$lvar' globally"

This gives output:

+ return_var='original return_var'
+ pass_back_a_string return_var
+ eval 'echo in pass_back_a_string, original return_var is $return_var'
++ echo in pass_back_a_string, original return_var is original return_var
in pass_back_a_string, original return_var is original return_var
+ eval 'return_var='\''foo bar rab oof'\'''
++ return_var='foo bar rab oof'
+ echo foo bar rab oof
foo bar rab oof
+ call_a_string_func
+ local 'lvar=original lvar'
+ pass_back_a_string lvar
+ eval 'echo in pass_back_a_string, original lvar is $lvar'
++ echo in pass_back_a_string, original lvar is original lvar
in pass_back_a_string, original lvar is original lvar
+ eval 'lvar='\''foo bar rab oof'\'''
++ lvar='foo bar rab oof'
+ echo 'lvar='\''foo bar rab oof'\'' locally'
lvar='foo bar rab oof' locally
+ echo 'lvar='\'''\'' globally'
lvar='' globally

1. Follow up the PySvc.py

2. changing the dll folder

I know this is old but I was stuck on this forever. For me, this specific problem was solved by copying this file - pywintypes36.dll

From -> Python36\Lib\site-packages\pywin32_system32

To -> Python36\Lib\site-packages\win32

setx /M PATH "%PATH%;C:\Users\user\AppData\Local\Programs\Python\Python38-32;C:\Users\user\AppData\Local\Programs\Python\Python38-32\Scripts;C:\Users\user\AppData\Local\Programs\Python\Python38-32\Lib\site-packages\pywin32_system32;C:\Users\user\AppData\Local\Programs\Python\Python38-32\Lib\site-packages\win32

3. changing the path to python folder by

cd C:\Users\user\AppData\Local\Programs\Python\Python38-32

4. NET START PySvc
5. NET STOP PySvc

MY PREFERRED METHOD is using fopen,fwrite and fclose [it will cost less CPU]

$f=fopen('myfile.txt','w');
fwrite($f,'new content');
fclose($f);

Warning for those using file_put_contents

It'll affect a lot in performance, for example [on the same class/situation] file_get_contents too: if you have a BIG FILE, it'll read the whole content in one shot and that operation could take a long waiting time

You should be able to name the buttons and give them a value; then map this name as an argument to the action. Alternatively, use 2 separate action-links or 2 forms.

Just create this batch command file in your game directory. Bat file takes one argument %1 as the username.

Also, I use a splash screen to make pretty. You will NOT be able to play online, but who cares.

Adjust your memory usage to fit your machine (-Xmx & -Xmns).

Here is some help for 2Tier and 3Tier difference, please refer below.

ANSWER:
1. 2Tier is Client server architecture and 3Tier is Client, Server and Database architecture.
2. 3Tier has a Middle stage to communicate client to server, Where as in 2Tier client directly get communication to server.
3. 3Tier is like a MVC, But having difference in topologies
4. 3Tier is linear means in that request flow is Client>>>Middle Layer(SErver application) >>>Databse server and Response is reverse.
While in 2Tier it a Triangular View >>Controller>>Model
5. 3Tier is like Website while web browser is Client application(middle layer), and ASP/PHP language code is server application.

Using imagemagick, you can try:

convert page.png page.pdf

Or for multiple images:

convert page*.png mydoc.pdf

Change in your html with adding the function on the button click

 <input type="button" value="Clear" onclick="javascript:eraseText();"> 
    <textarea id='output' rows=20 cols=90></textarea>

Try this in your js file:

function eraseText() {
    document.getElementById("output").value = "";
}

I suspect that the line

DataTO.Id = Convert.ToInt64(dataAccCom.GetParameterValue(IDbCmd, "op_Id"));

is causing the problem. Is it possible that the op_Id value is being set to null by the stored procedure?

To Guard against it use the Convert.IsDBNull method. For example:

if (!Convert.IsDBNull(dataAccCom.GetParameterValue(IDbCmd, "op_Id"))
{
 DataTO.Id = Convert.ToInt64(dataAccCom.GetParameterValue(IDbCmd, "op_Id"));
}
else 
{
 DataTO.Id = ...some default value or perform some error case management
}

Unfortunately this answer is probably of little or no help whatsoever, but I did a forensics analysis of the Java Lambda Mailing list to see if I could find the cause of this design. This is what I found out.

In the beginning there was an instance method for Stream.concat(Stream)

In the mailing list I can clearly see the method was originally implemented as an instance method, as you can read in this thread by Paul Sandoz, about the concat operation.

In it they discuss the issues that could arise from those cases in which the stream could be infinite and what concatenation would mean in those cases, but I do not think that was the reason for the modification.

You see in this other thread that some early users of the JDK 8 questioned about the behavior of the concat instance method when used with null arguments.

This other thread reveals, though, that the design of the concat method was under discussion.

Refactored to Streams.concat(Stream,Stream)

But without any explanation, suddenly, the methods were changed to static methods, as you can see in this thread about combining streams. This is perhaps the only mail thread that sheds a bit of light about this change, but it was not clear enough for me to determine the reason for the refactoring. But we can see they did a commit in which they suggested to move the concat method out of Stream and into the helper class Streams.

Refactored to Stream.concat(Stream,Stream)

Later, it was moved again from Streams to Stream, but yet again, no explanation for that.

So, bottom line, the reason for the design is not entirely clear for me and I could not find a good explanation. I guess you could still ask the question in the mailing list.

Some Alternatives for Stream Concatenation

This other thread by Michael Hixson discusses/asks about other ways to combine/concat streams

1. To combine two streams, I should do this:

   Stream.concat(s1, s2)
   

   not this:

   Stream.of(s1, s2).flatMap(x -> x)
   

   ... right?

2. To combine more than two streams, I should do this:

   Stream.of(s1, s2, s3, ...).flatMap(x -> x)
   

   not this:

   Stream.of(s1, s2, s3, ...).reduce(Stream.empty(), Stream::concat)
   

   ... right?

Regardless of the echo (which would need to be replaced with print_r or var_dump), if an exception is thrown the object should stay empty:

DOMNodeList Object
(
)

Solution

1. Set recover to true, and strictErrorChecking to false

   $content = file_get_contents($url);
   
   $doc = new DOMDocument();
   $doc->recover = true;
   $doc->strictErrorChecking = false;
   $doc->loadHTML($content);
   

2. Use php's entity-encoding on the markup's contents, which is a most common error source.

By default, np.genfromtxt uses dtype=float: that's why you string columns are converted to NaNs because, after all, they're Not A Number...

You can ask np.genfromtxt to try to guess the actual type of your columns by using dtype=None:

>>> from StringIO import StringIO
>>> test = "a,1,2\nb,3,4"
>>> a = np.genfromtxt(StringIO(test), delimiter=",", dtype=None)
>>> print a
array([('a',1,2),('b',3,4)], dtype=[('f0', '|S1'),('f1', '<i8'),('f2', '<i8')])

You can access the columns by using their name, like a['f0']...

Using dtype=None is a good trick if you don't know what your columns should be. If you already know what type they should have, you can give an explicit dtype. For example, in our test, we know that the first column is a string, the second an int, and we want the third to be a float. We would then use

>>> np.genfromtxt(StringIO(test), delimiter=",", dtype=("|S10", int, float))
array([('a', 1, 2.0), ('b', 3, 4.0)], 
      dtype=[('f0', '|S10'), ('f1', '<i8'), ('f2', '<f8')])

Using an explicit dtype is much more efficient than using dtype=None and is the recommended way.

In both cases (dtype=None or explicit, non-homogeneous dtype), you end up with a structured array.

[Note: With dtype=None, the input is parsed a second time and the type of each column is updated to match the larger type possible: first we try a bool, then an int, then a float, then a complex, then we keep a string if all else fails. The implementation is rather clunky, actually. There had been some attempts to make the type guessing more efficient (using regexp), but nothing that stuck so far]

ser.read(64) should be ser.read(size=64); ser.read uses keyword arguments, not positional.

Also, you're reading from the port twice; what you probably want to do is this:

i=0
for modem in PortList:
    for port in modem:
        try:
            ser = serial.Serial(port, 9600, timeout=1)
            ser.close()
            ser.open()
            ser.write("ati")
            time.sleep(3)
            read_val = ser.read(size=64)
            print read_val
            if read_val is not '':
                print port
        except serial.SerialException:
            continue
        i+=1

Note that rstrip doesn't act exactly like Perl's chomp() because it doesn't modify the string. That is, in Perl:

$x="a\n";

chomp $x

results in $x being "a".

but in Python:

x="a\n"

x.rstrip()

will mean that the value of x is still "a\n". Even x=x.rstrip() doesn't always give the same result, as it strips all whitespace from the end of the string, not just one newline at most.

There are several problems in your code.

First the big ones:

1. You are creating a new figure and a new axes in every iteration of your loop ? put fig = plt.figure and ax = fig.add_subplot(1,1,1) outside of the loop.

2. Don't use the Locators. Call the functions ax.set_xticks() and ax.grid() with the correct keywords.

3. With plt.axes() you are creating a new axes again. Use ax.set_aspect('equal').

The minor things: You should not mix the MATLAB-like syntax like plt.axis() with the objective syntax. Use ax.set_xlim(a,b) and ax.set_ylim(a,b)

This should be a working minimal example:

import numpy as np
import matplotlib.pyplot as plt

fig = plt.figure()
ax = fig.add_subplot(1, 1, 1)

# Major ticks every 20, minor ticks every 5
major_ticks = np.arange(0, 101, 20)
minor_ticks = np.arange(0, 101, 5)

ax.set_xticks(major_ticks)
ax.set_xticks(minor_ticks, minor=True)
ax.set_yticks(major_ticks)
ax.set_yticks(minor_ticks, minor=True)

# And a corresponding grid
ax.grid(which='both')

# Or if you want different settings for the grids:
ax.grid(which='minor', alpha=0.2)
ax.grid(which='major', alpha=0.5)

plt.show()

Output is this:

You're talking about template literals.

They allow for both multiline strings and string interpolation.

Multiline strings:

console.log(`foo_x000D_
bar`);_x000D_
// foo_x000D_
// bar

String interpolation:

var foo = 'bar';_x000D_
console.log(`Let's meet at the ${foo}`);_x000D_
// Let's meet at the bar

Bash allows you to place strings adjacently, and they'll just end up being glued together.

So this:

$ echo "Hello"', world!'

produces

Hello, world!

The trick is to alternate between single and double-quoted strings as required. Unfortunately, it quickly gets very messy. For example:

$ echo "I like to use" '"double quotes"' "sometimes"

produces

I like to use "double quotes" sometimes

In your example, I would do it something like this:

$ dbtable=example
$ dbload='load data local infile "'"'gfpoint.csv'"'" into '"table $dbtable FIELDS TERMINATED BY ',' ENCLOSED BY '"'"'"' LINES "'TERMINATED BY "'"'\n'"'" IGNORE 1 LINES'
$ echo $dbload

which produces the following output:

load data local infile "'gfpoint.csv'" into table example FIELDS TERMINATED BY ',' ENCLOSED BY '"' LINES TERMINATED BY "'\n'" IGNORE 1 LINES

It's difficult to see what's going on here, but I can annotate it using Unicode quotes. The following won't work in bash – it's just for illustration:

dbload=‘load data local infile "’“'gfpoint.csv'”‘" into’“table $dbtable FIELDS TERMINATED BY ',' ENCLOSED BY '”‘"’“' LINES”‘TERMINATED BY "’“'\n'”‘" IGNORE 1 LINES’

The quotes like “ ‘ ’ ” in the above will be interpreted by bash. The quotes like " ' will end up in the resulting variable.

If I give the same treatment to the earlier example, it looks like this:

$ echo“I like to use”‘"double quotes"’“sometimes”

Solved it. So by default, all packages that falls under @SpringBootApplication declaration will be scanned.

Assuming my main class ExampleApplication that has @SpringBootApplication declaration is declared inside com.example.something, then all components that falls under com.example.something is scanned while com.example.applicant will not be scanned.

So, there are two ways to do it based on this question. Use

@SpringBootApplication(scanBasePackages={
"com.example.something", "com.example.application"})

That way, the application will scan all the specified components, but I think what if the scale were getting bigger ?

So I use the second approach, by restructuring my packages and it worked ! Now my packages structure became like this.

src/
+-- main/
¦   +-- java/
|       +-- com.example/
|       |   +-- Application.java
|       +-- com.example.model/
|       |   +-- User.java
|       +-- com.example.controller/
|       |   +-- IndexController.java
|       |   +-- UsersController.java
|       +-- com.example.service/
|           +-- UserService.java
+-- resources/
    +-- application.properties

HTML5 download attribute

Just to allow user to download the image or other file you may use the HTML5 download attribute.

Static file download

<a href="/images/image-name.jpg" download>
<!-- OR -->
<a href="/images/image-name.jpg" download="new-image-name.jpg"> 

Dynamic file download

In cases requesting image dynamically it is possible to emulate such download.

If your image is already loaded and you have the base64 source then:

function saveBase64AsFile(base64, fileName) {
    var link = document.createElement("a");

    document.body.appendChild(link); // for Firefox

    link.setAttribute("href", base64);
    link.setAttribute("download", fileName);
    link.click();
}

Otherwise if image file is downloaded as Blob you can use FileReader to convert it to Base64:

function saveBlobAsFile(blob, fileName) {
    var reader = new FileReader();

    reader.onloadend = function () {    
        var base64 = reader.result ;
        var link = document.createElement("a");

        document.body.appendChild(link); // for Firefox

        link.setAttribute("href", base64);
        link.setAttribute("download", fileName);
        link.click();
    };

    reader.readAsDataURL(blob);
}

Firefox

The anchor tag you are creating also needs to be added to the DOM in Firefox, in order to be recognized for click events (Link).

IE is not supported: Caniuse link

They both are indeed synonymous, However i found the small difference between them,

1)You cannot use Int32 while creatingenum

enum Test : Int32
{ XXX = 1   // gives you compilation error
}

enum Test : int
{ XXX = 1   // Works fine
}

2) Int32 comes under System declaration. if you remove using.System you will get compilation error but not in case for int

CSTR({number_field}, 0, '')

The second placeholder is for decimals.

The last placeholder is for thousands separator.

The following works for me (Excel 2010)

Dim b1 As Button

Set b1 = ActiveSheet.Buttons("Button 1")

b1.Font.ColorIndex = 15
b1.Enabled = False
Application.Cursor = xlWait
Call aLongAction
b1.Enabled = True
b1.Font.ColorIndex = 1
Application.Cursor = xlDefault

Be aware that .enabled = False does not gray out a button.

The font color has to be set explicitely to get it grayed.

No, you cannot. But you can create a user defined table function.

Use this:

android:background="@android:color/transparent"

To multiply, use mult for signed multiplication and multu for unsigned multiplication. Note that the result of the multiplication of two 32-bit numbers yields a 64-number. If you want the result back in $v0 that means that you assume the result will fit in 32 bits.

The 32 most significant bits will be held in the HI special register (accessible by mfhi instruction) and the 32 least significant bits will be held in the LO special register (accessible by the mflo instruction):

E.g.:

li $a0, 5
li $a1, 3
mult $a0, $a1
mfhi $a2 # 32 most significant bits of multiplication to $a2
mflo $v0 # 32 least significant bits of multiplication to $v0

To divide, use div for signed division and divu for unsigned division. In this case, the HI special register will hold the remainder and the LO special register will hold the quotient of the division.

E.g.:

div $a0, $a1
mfhi $a2 # remainder to $a2
mflo $v0 # quotient to $v0

I came across this thread while trying to clear the date already set. Attempting:

$('#datepicker').val('').datepicker('update');

produced:

TypeError: t.dpDiv is undefined 
https://ajax.googleapis.com/ajax/libs/jqueryui/1.11.2/jquery-ui.min.js -- Line 8

Thinking that perhaps one needed to include the original Datepicker for bootstrap removes the error, but then causes the original Datepicker widget to appear! - so that's obviously wrong and not needed.

Looking further, the crash in jqueryui is in:

    /* Generate the date picker content. */
_updateDatepicker: function(inst) {
    this.maxRows = 4; //Reset the max number of rows being displayed (see #7043)
    datepicker_instActive = inst; // for delegate hover events
    inst.dpDiv.empty().append(this._generateHTML(inst));
    this._attachHandlers(inst);

and inst.pdDiv does not exist.

Investigating further - I realized that what was needed was:

        $formControl = $duedate.find("input");
        $formControl.val('');
        $formControl.removeData();

Which solved my problem. Note I also needed the $formControl.removeData() otherwise the state of the widget would not be reinitialized to the initial state.

I hope this helps someone else. :-)

I don't like the solution of settings widths on .btn because it assumes there'll always be the same number of items in the .btn-group. This is a faulty assumption and leads to bloated, presentation-specific CSS.

A better solution is to change how .btn-group with .btn-block and child .btn(s) are display. I believe this is what you're looking for:

.btn-group.btn-block {
    display: table;
}
.btn-group.btn-block > .btn {
    display: table-cell;
}

Here's a fiddle: http://jsfiddle.net/DEwX8/123/

If you'd prefer to have equal-width buttons (within reason) and can support only browsers that support flexbox, try this instead:

.btn-group.btn-block {
    display: flex;
}
.btn-group.btn-block > .btn {
    flex: 1;
}

Here's a fiddle: http://jsfiddle.net/DEwX8/124/

You'd use the corresponding method getVisibility(). Method names prefixed with 'get' and 'set' are Java's convention for representing properties. Some language have actual language constructs for properties but Java isn't one of them. So when you see something labeled 'setX', you can be 99% certain there's a corresponding 'getX' that will tell you the value.

I am pretty sure this is a duplicate. Anyway, have a look at the following piece of code

x <- seq(5, 15, length=1000)
y <- dnorm(x, mean=10, sd=3)
plot(x, y, type="l", lwd=1)

I'm sure you can work the rest out yourself, for the title you might want to look for something called main= and y-axis labels are also up to you.

If you want to see more of the tails of the distribution, why don't you try playing with the seq(5, 15, ) section? Finally, if you want to know more about what dnorm is doing I suggest you look here

Pass float to sleep, like sleep 0.1

Basically I want to clear the views cache.

There is now a command in Laravel 5.1 for that

php artisan view:clear

You can use the Feed URL "Direct URL" option, as described on the Feed Dialog page:

You can also bring up a Feed Dialog by explicitly directing the user to the /dialog/feed endpoint:

  https://www.facebook.com/dialog/feed?  
  app_id=123050457758183&
  link=https://developers.facebook.com/docs/reference/dialogs/&
  picture=http://fbrell.com/f8.jpg&
  name=Facebook%20Dialogs&
  caption=Reference%20Documentation&
  description=Using%20Dialogs%20to%20interact%20with%20users.&
  redirect_uri=http://www.example.com/response`

Looks like they no longer mention "sharing" anywhere in their docs; this has been replaced with the concept of adding to your Feed.

If you are using virtualenv, it is not as trivial to get the driver using the installer. What you can do then: install it as described by Devon. Then copy over cx_Oracle.pyd and the cx_Oracle-XXX.egg-info folder from Python\Lib\site-packages into the Lib\site-packages from your virtual env. Of course, also here, architecture and version are important.

First you need to compose the message. The bare minimum is composed of these two headers:

MIME-Version: 1.0
Content-Type: text/html

... and the appropriate message body:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head><title></title>
</head>
<body>

<p>Hello, world!</p>

</body>
</html>

Once you have it, you can pass the appropriate information to the mail command:

body = '...'

echo $body | mail \
-a "From: [email protected]" \
-a "MIME-Version: 1.0" \
-a "Content-Type: text/html" \
-s "This is the subject" \
[email protected]

This is an oversimplified example, since you also need to take care of charsets, encodings, maximum line length... But this is basically the idea.

Alternatively, you can write your script in Perl or PHP rather than plain shell.

Update

A shell script is basically a text file with Unix line endings that starts with a line called shebang that tells the shell what interpreter it must pass the file to, follow some commands in the language the interpreter understands and has execution permission (in Unix that's a file attribute). E.g., let's say you save the following as hello-world:

#!/bin/sh

echo Hello, world!

Then you assign execution permission:

chmod +x hello-world

And you can finally run it:

./hello-world

Whatever, this is kind of unrelated to the original question. You should get familiar with basic shell scripting before doing advanced tasks with it. Here you are a couple of links about bash, a popular shell:

http://www.gnu.org/software/bash/manual/html_node/index.html

http://tldp.org/HOWTO/Bash-Prog-Intro-HOWTO.html

Something to note here. We had the same issue with Windows VM's running on an ESXi host. The time sync was turned on in VMWare Tools on the guest, but the guest clocks were consistently off (by about 30 seconds) from the host clock. The ESXi host was configured to get time updates from an internal time server.

It turns out we had the Internet Time setting turned on in the Windows VM's (Control Panel > Date and Time > Internet Time tab) so the guest was getting time updates from two places and the internet time was winning. We turned that off and now the guest clocks are good, getting their time exclusively from the ESXi host.

I don't think you can skip rows in a different format with BULK INSERT/BCP.

When I run this:

TRUNCATE TABLE so1029384

BULK INSERT so1029384
FROM 'C:\Data\test\so1029384.txt'
WITH
(
--FIRSTROW = 2,
FIELDTERMINATOR= '|',
ROWTERMINATOR = '\n'
)

SELECT * FROM so1029384

I get:

col1                                               col2                                               col3

It looks like it requires the '|' even in the header data, because it reads up to that into the first column - swallowing up a newline into the first column. Obviously if you include a field terminator parameter, it expects that every row MUST have one.

You could strip the row with a pre-processing step. Another possibility is to select only complete rows, then process them (exluding the header). Or use a tool which can handle this, like SSIS.

IRI (RFC 3987) is the latest standard that replaces the URI/URL (RFC 3986 and older) standards. URI/URL do not natively support Unicode (well, RFC 3986 adds provisions for future URI/URL-based protocols to support it, but does not update past RFCs). The "%uXXXX" scheme is a non-standard extension to allow Unicode in some situations, but is not universally implemented by everyone. IRI, on the other hand, fully supports Unicode, and requires that text be encoded as UTF-8 before then being percent-encoded.

Also create PATH enviroment variable on you computer like this (if it doesn't exist already):

1. Right click on My Computer/Computer
2. Properties
3. Advanced system settings (or just Advanced)
4. Enviroment variables
5. If PATH variable doesn't exist among "User variables" click New (Variable name: PATH, Variable value : C:\Program Files\Java\jdk1.8.0\bin; <-- please check out the right version, this may differ as Oracle keeps updating Java). ; in the end enables assignment of multiple values to PATH variable.
6. Click OK! Done

To be sure that everything works, open CMD Prompt and type: java -version to check for Java version and javac to be sure that compiler responds.

I hope this helps. Good luck!

Since the Logical Address space is 32-bit long that means program size is 2^32 bytes i.e. 4GB. Now we have the page size of 4KB i.e.2^12 bytes.Thus the number of pages in program are 2^20.(no. of pages in program = program size/page size).Now the size of page table entry is 4 byte hence the size of page table is 2^20*4 = 4MB(size of page table = no. of pages in program * page table entry size). Hence 4MB space is required in Memory to store the page table.

Adding on to @Alexandre Aimbiré's answer - sometimes you may need to specify z-index:1 to have the element always on top while scrolling. Like this:

position: -webkit-sticky; /* Safari & IE */
position: sticky;
top: 0;
z-index: 1;

You're not using splice correctly:

arr.splice(4, 1)

this will remove 1 item at index 4. see here

I think you want to use slice:

arr.slice(0,5)

this will return elements in position 0 through 4.

This assumes all the rest of your code (cookies etc) works correctly

In Font Awesome 5 it can be done using pure CSS as in some of the above answers with some modifications.

ul {
  list-style-type: none;
}

li:before {
  position: absolute;
  font-family: 'Font Awesome 5 free';
          /*  Use the Name of the Font Awesome free font, e.g.:
           - 'Font Awesome 5 Free' for Regular and Solid symbols;
           - 'Font Awesome 5 Brand' for Brands symbols.
           - 'Font Awesome 5 Pro' for Regular and Solid symbols (Professional License);
          */
  content: "\f1fc"; /* Unicode value of the icon to use: */
  font-weight: 900; /* This is important, change the value according to the font family name
                       used above. See the link below  */
  color: red;
}

Without the correct font-weight, it will only show a blank square.
