You should be able to transfer the Application to another Username. You would need all your old user information to transfer it. The application would remove it's self from old account to new account. Also you could put a limit on how many times you where allowed to transfer it. If you transfer it to the application could expire after a year and force to buy update.

if using /bin/sh you can use:

if [ <condition> ] && [ <condition> ]; then
    ...
fi

if using /bin/bash you can use:

if [[ <condition> && <condition> ]]; then
    ...
fi

While @tymeJV gave a correct answer, the way to do this to be inline with angular would be:

ng-click="hidePrefs()"

and then in your controller:

$scope.hidePrefs = function() {  
  $scope.prefs = false;
}

Also make sure you do not wrap parentheses around your query string like so:

SELECT Name from [USER] WHERE [UserId] in (@ids)

I had this cause a SQL Syntax error using Dapper 1.50.2, fixed by removing parentheses

SELECT Name from [USER] WHERE [UserId] in @ids

Going down your list:

• "Unicode" isn't an encoding, although unfortunately, a lot of documentation imprecisely uses it to refer to whichever Unicode encoding that particular system uses by default. On Windows and Java, this often means UTF-16; in many other places, it means UTF-8. Properly, Unicode refers to the abstract character set itself, not to any particular encoding.
• UTF-16: 2 bytes per "code unit". This is the native format of strings in .NET, and generally in Windows and Java. Values outside the Basic Multilingual Plane (BMP) are encoded as surrogate pairs. These used to be relatively rarely used, but now many consumer applications will need to be aware of non-BMP characters in order to support emojis.
• UTF-8: Variable length encoding, 1-4 bytes per code point. ASCII values are encoded as ASCII using 1 byte.
• UTF-7: Usually used for mail encoding. Chances are if you think you need it and you're not doing mail, you're wrong. (That's just my experience of people posting in newsgroups etc - outside mail, it's really not widely used at all.)
• UTF-32: Fixed width encoding using 4 bytes per code point. This isn't very efficient, but makes life easier outside the BMP. I have a .NET Utf32String class as part of my MiscUtil library, should you ever want it. (It's not been very thoroughly tested, mind you.)
• ASCII: Single byte encoding only using the bottom 7 bits. (Unicode code points 0-127.) No accents etc.
• ANSI: There's no one fixed ANSI encoding - there are lots of them. Usually when people say "ANSI" they mean "the default locale/codepage for my system" which is obtained via Encoding.Default, and is often Windows-1252 but can be other locales.

There's more on my Unicode page and tips for debugging Unicode problems.

The other big resource of code is unicode.org which contains more information than you'll ever be able to work your way through - possibly the most useful bit is the code charts.

If Source Date format isn't consistent there is some problem with substr function, e.g.:

1/1/2017 or 1/11/2017 or 11/11/2017 or 1/1/17 etc.

So I followed a different apporach using a temporary table. This snippet outputs 'YYYY-MM-DD' + time if exists.

Note that this version accepts Day/Month/Year format. If you want Month/Day/Year swap the first two variables DayPart and MonthPart. Also, two year dates '44-'99 assumes 1944-1999 whereas '00-'43 assumes 2000-2043.

 BEGIN;

    CREATE TEMP TABLE [DateconvertionTable] (Id TEXT PRIMARY KEY, OriginalDate  TEXT  , SepA  INTEGER,  DayPart TEXT,Rest1 TEXT, SepB  INTEGER,  MonthPart TEXT, Rest2 TEXT, SepC  INTEGER,  YearPart TEXT, Rest3 TEXT, NewDate TEXT);
    INSERT INTO [DateconvertionTable] (Id,OriginalDate)  SELECT SourceIdColumn, SourceDateColumn From  [SourceTable];

    --day Part (If day is first)

    UPDATE [DateconvertionTable] SET SepA=instr(OriginalDate ,'/');
    UPDATE [DateconvertionTable] SET DayPart=substr(OriginalDate,1,SepA-1) ;
    UPDATE [DateconvertionTable] SET Rest1=substr(OriginalDate,SepA+1);

    --Month Part (If Month is second)

    UPDATE [DateconvertionTable] SET SepB=instr(Rest1,'/');
    UPDATE [DateconvertionTable]  SET MonthPart=substr(Rest1, 1,SepB-1);
    UPDATE [DateconvertionTable] SET Rest2=substr(Rest1,SepB+1);

    --Year Part (3d)

    UPDATE [DateconvertionTable] SET SepC=instr(Rest2,' ');

           --Use Cases In case of time string included
    UPDATE [DateconvertionTable]  SET YearPart= CASE WHEN SepC=0 THEN Rest2 ELSE substr(Rest2,1,SepC-1)  END;

           --The Rest considered time
    UPDATE [DateconvertionTable]  SET Rest3= CASE WHEN SepC=0 THEN  '' ELSE substr(Rest2,SepC+1) END;

           -- Convert 1 digit day and month to 2 digit
    UPDATE [DateconvertionTable] SET DayPart=0||DayPart WHERE CAST(DayPart AS INTEGER)<10;
    UPDATE [DateconvertionTable] SET MonthPart=0||MonthPart WHERE CAST(MonthPart AS INTEGER)<10;

           --If there is a need to convert 2 digit year to 4 digit year, make some assumptions...
    UPDATE [DateconvertionTable] SET YearPart=19||YearPart WHERE CAST(YearPart AS INTEGER)>=44 AND CAST(YearPart AS INTEGER)<100;
    UPDATE [DateconvertionTable] SET YearPart=20||YearPart WHERE CAST(YearPart AS INTEGER)<44 AND CAST(YearPart AS INTEGER)<100;

    UPDATE [DateconvertionTable] SET NewDate = YearPart  || '-' || MonthPart || '-' || DayPart || ' ' || Rest3;  

    UPDATE [SourceTable] SET SourceDateColumn=(Select NewDate FROM DateconvertionTable WHERE [DateconvertionTable].id=SourceIdColumn);
    END;

ORDER BY: sort the data in ascending or descending order.

Consider the CUSTOMERS table:

+----+----------+-----+-----------+----------+
| ID | NAME     | AGE | ADDRESS   | SALARY   |
+----+----------+-----+-----------+----------+
|  1 | Ramesh   |  32 | Ahmedabad |  2000.00 |
|  2 | Khilan   |  25 | Delhi     |  1500.00 |
|  3 | kaushik  |  23 | Kota      |  2000.00 |
|  4 | Chaitali |  25 | Mumbai    |  6500.00 |
|  5 | Hardik   |  27 | Bhopal    |  8500.00 |
|  6 | Komal    |  22 | MP        |  4500.00 |
|  7 | Muffy    |  24 | Indore    | 10000.00 |
+----+----------+-----+-----------+----------+

Following is an example, which would sort the result in ascending order by NAME:

SQL> SELECT * FROM CUSTOMERS
     ORDER BY NAME;

This would produce the following result:

+----+----------+-----+-----------+----------+
| ID | NAME     | AGE | ADDRESS   | SALARY   |
+----+----------+-----+-----------+----------+
|  4 | Chaitali |  25 | Mumbai    |  6500.00 |
|  5 | Hardik   |  27 | Bhopal    |  8500.00 |
|  3 | kaushik  |  23 | Kota      |  2000.00 |
|  2 | Khilan   |  25 | Delhi     |  1500.00 |
|  6 | Komal    |  22 | MP        |  4500.00 |
|  7 | Muffy    |  24 | Indore    | 10000.00 |
|  1 | Ramesh   |  32 | Ahmedabad |  2000.00 |
+----+----------+-----+-----------+----------+

GROUP BY: arrange identical data into groups.

Now, CUSTOMERS table has the following records with duplicate names:

+----+----------+-----+-----------+----------+
| ID | NAME     | AGE | ADDRESS   | SALARY   |
+----+----------+-----+-----------+----------+
|  1 | Ramesh   |  32 | Ahmedabad |  2000.00 |
|  2 | Ramesh   |  25 | Delhi     |  1500.00 |
|  3 | kaushik  |  23 | Kota      |  2000.00 |
|  4 | kaushik  |  25 | Mumbai    |  6500.00 |
|  5 | Hardik   |  27 | Bhopal    |  8500.00 |
|  6 | Komal    |  22 | MP        |  4500.00 |
|  7 | Muffy    |  24 | Indore    | 10000.00 |
+----+----------+-----+-----------+----------+

if you want to group identical names into single name, then GROUP BY query would be as follows:

SQL> SELECT * FROM CUSTOMERS
     GROUP BY NAME;

This would produce the following result: (for identical names it would pick the last one and finally sort the column in ascending order)

    +----+----------+-----+-----------+----------+   
    | ID | NAME     | AGE | ADDRESS   | SALARY   |
    +----+----------+-----+-----------+----------+
    |  5 | Hardik   |  27 | Bhopal    |  8500.00 |
    |  4 | kaushik  |  25 | Mumbai    |  6500.00 |
    |  6 | Komal    |  22 | MP        |  4500.00 |
    |  7 | Muffy    |  24 | Indore    | 10000.00 |
    |  2 | Ramesh   |  25 | Delhi     |  1500.00 |
    +----+----------+-----+-----------+----------+

as you have inferred that it is of no use without SQL functions like sum,avg etc..

so go through this definition to understand the proper use of GROUP BY:

A GROUP BY clause works on the rows returned by a query by summarizing identical rows into a single/distinct group and returns a single row with the summary for each group, by using appropriate Aggregate function in the SELECT list, like COUNT(), SUM(), MIN(), MAX(), AVG(), etc.

Now, if you want to know the total amount of salary on each customer(name), then GROUP BY query would be as follows:

SQL> SELECT NAME, SUM(SALARY) FROM CUSTOMERS
     GROUP BY NAME;

This would produce the following result: (sum of the salaries of identical names and sort the NAME column after removing identical names)

+---------+-------------+
| NAME    | SUM(SALARY) |
+---------+-------------+
| Hardik  |     8500.00 |
| kaushik |     8500.00 |
| Komal   |     4500.00 |
| Muffy   |    10000.00 |
| Ramesh  |     3500.00 |
+---------+-------------+

Do you have to do it with Ajax? Coouldn't it be a possibility to load it in an iframe?

I wrote two little C function based on cafs answer to calculate the user+kernel cpu usage of of an process: https://github.com/fho/code_snippets/blob/master/c/getusage.c

The answers here are useful as a general guidance about await/async. They also contain some detail about how await/async is wired. I would like to share some practical experience with you that you should know before using this design pattern.

The term "await" is literal, so whatever thread you call it on will wait for the result of the method before continuing. On the foreground thread, this is a disaster. The foreground thread carries the burden of constructing your app, including views, view models, initial animations, and whatever else you have boot-strapped with those elements. So when you await the foreground thread, you stop the app. The user waits and waits when nothing appears to happen. This provides a negative user experience.

You can certainly await a background thread using a variety of means:

Device.BeginInvokeOnMainThread(async () => { await AnyAwaitableMethod(); });

// Notice that we do not await the following call, 
// as that would tie it to the foreground thread.
try
{
Task.Run(async () => { await AnyAwaitableMethod(); });
}
catch
{}

The complete code for these remarks is at https://github.com/marcusts/xamarin-forms-annoyances. See the solution called AwaitAsyncAntipattern.sln.

The GitHub site also provides links to a more detailed discussion on this topic.

Associative Arrays in JavaScript don't really work the same as they do in other languages. for each statements are complicated (because they enumerate inherited prototype properties). You could declare properties on an object/associative array as Pointy mentioned, but really for this sort of thing you should use an array with the push method:

jsArr = []; 

for (var i = 1; i <= 10; i++) { 
    jsArr.push('example ' + 1); 
} 

Just don't forget that indexed arrays are zero-based so the first element will be jsArr[0], not jsArr[1].

I was having similar issue and adding

 sessionFactory.setAnnotatedClasses(User.class);

this line helped but before that I was having

sessionFactory.setPackagesToScan(new String[] { "com.rg.spring.model" });

I am not sure why that one is not working.User class is under com.rg.spring.model Please let me know how to get it working via packagesToScan method.

You can do:

timeStamp.toLocalDateTime().toLocalDate();

Note that timestamp.toLocalDateTime() will use the Clock.systemDefaultZone() time zone to make the conversion. This may or may not be what you want.

This function can sum up all the numbers -

 function array(arr){
   var sum = 0;
   for (var i = 0; i< arr.length; i++){
    sum += arr[i];
   }
   console.log(sum);
 }
 array([5, 1, 3, 3])

If you use dplyr package you can do:

library(dplyr)
filter(df, aged <= laclen)

If the variable is a parameter then you could use advanced function parameter binding like below to validate not null or empty:

[CmdletBinding()]
Param (
    [parameter(mandatory=$true)]
    [ValidateNotNullOrEmpty()]
    [string]$Version
)

This will recursively traverse the /path/to/folder directory and list only the symbolic links:

ls -lR /path/to/folder | grep ^l

If your intention is to follow the symbolic links too, you should use your find command but you should include the -L option; in fact the find man page says:

   -L     Follow symbolic links.  When find examines or prints information
          about files, the information used shall be taken from the  prop-
          erties  of  the file to which the link points, not from the link
          itself (unless it is a broken symbolic link or find is unable to
          examine  the file to which the link points).  Use of this option
          implies -noleaf.  If you later use the -P option,  -noleaf  will
          still  be  in  effect.   If -L is in effect and find discovers a
          symbolic link to a subdirectory during its search, the subdirec-
          tory pointed to by the symbolic link will be searched.

          When the -L option is in effect, the -type predicate will always
          match against the type of the file that a symbolic  link  points
          to rather than the link itself (unless the symbolic link is bro-
          ken).  Using -L causes the -lname and -ilname predicates  always
          to return false.

Then try this:

find -L /var/www/ -type l

This will probably work: I found in the find man page this diamond: if you are using the -type option you have to change it to the -xtype option:

          l      symbolic link; this is never true if the -L option or the
                 -follow option is in effect, unless the symbolic link  is
                 broken.  If you want to search for symbolic links when -L
                 is in effect, use -xtype.

Then:

find -L /var/www/ -xtype l

Had the same issue, my app is behind nginx. Making these changes to my Nginx config removed the error.

location / {
proxy_pass http://localhost:8080;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_set_header Host $host;
}

I would change your service layer to:

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

as you have it, you are still running your _service.Process call synchronously, and gaining very little or no benefit from awaiting it.

With this approach, you are wrapping the potentially slow call in a Task, starting it, and returning it to be awaited. Now you get the benefit of awaiting the Task.

You also can lead your initial string, which you are going to check for pattern matching, to lower case. And use in your pattern lower case symbols respectively.

Have a look at this jsfiddle.

The idea is to filter rows with function which will loop through words.

jo.filter(function (i, v) {
    var $t = $(this);
    for (var d = 0; d < data.length; ++d) {
        if ($t.is(":contains('" + data[d] + "')")) {
            return true;
        }
    }
    return false;
})
//show the rows that match.
.show();

EDIT: Note that case insensitive filtering cannot be achieved using :contains() selector but luckily there's text() function so filter string should be uppercased and condition changed to if ($t.text().toUpperCase().indexOf(data[d]) > -1). Look at this jsfiddle.

If you select the log entry to which you want to revert to then you can click on "Reset to this commit". Only use this option if you didn't push the reverse commit changes. If you're worried about losing the changes then you can use the soft mode which will leave a set of uncommitted changes (what you just changed). Using the mixed resets the working copy but keeps those changes, and a hard will just get rid of the changes entirely. Here's some screenshots:

In the Drupal content management system, 'hook' has a relatively specific meaning. When an internal event occurs (like content creation or user login, for example), modules can respond to the event by implementing a special "hook" function. This is done via naming convention -- [your-plugin-name]_user_login() for the User Login event, for example.

Because of this convention, the underlying events are referred to as "hooks" and appear with names like "hook_user_login" and "hook_user_authenticate()" in Drupal's API documentation.

Why don't you insert a map using the MapView object instead of MapFragment ? I am not sure if there is any limitation in MapView,though i found it helpful.

Choose Open Transcript from the ... dropdown to the right of the vote up/down and share links.

This will open a Transcript scrolling div on the right side.

You can then use Copy. Note that you cannot use Select All but need to click the top line, then scroll to the bottom using the scroll thumb, and then shift-click on the last line.

Note that you can also search within this text using the normal web page search.

The answer is here: http://php.net/manual/en/function.mysql-list-fields.php I'd use the following code in your case:

$result = mysql_query("SHOW COLUMNS FROM sometable");
if (!$result) {
    echo 'Could not run query: ' . mysql_error();
    exit;
}
$fields = array();
if (mysql_num_rows($result) > 0) {
    while ($row = mysql_fetch_assoc($result)) {
        $fields[] = $row['Field'];
    }
}

window.onresize = function(){
    var img = document.getElementById('fullsize');
    img.style.width = "100%";
};

In IE onresize event gets fired on every pixel change (width or height) so there could be performance issue. Delay image resizing for few milliseconds by using javascript's window.setTimeout().

Magic:

$ git svn clone http://svn/repo/here/trunk

Git and SVN operate very differently. You need to learn Git, and if you want to track changes from SVN upstream, you need to learn git-svn. The git-svn main page has a good examples section:

$ git svn --help

$dateString = '08/04/2010 22:15:00';
$dateObject = new DateTime($dateString);
echo $dateObject->format('h:i A');

For reference, I had this error message and the solution was that when you specify the library you miss the 'lib' off the front and the '.so' from the end.

So, if you have a file libmyfablib.so, you need to call:

   System.loadLibrary("myfablib"); // this loads the file 'libmyfablib.so' 

Having looked in the apk, installed/uninstalled and tried all kinds of complex solutions I couldn't see the simple problem that was right in front of my face!

The extra [ ] on the outside of your second syntax are unnecessary, and possibly confusing. You may use them, but if you must you need to have whitespace between them.

Alternatively:

while [ $stats -gt 300 ] || [ $stats -eq 0 ]

Just for sake of completeness, you can also use the same technique above with excel tables.

In the example below, I'm looking of a text in any cell of a Excel Table named "tblConfig", place in the sheet named Config that normally is set to be hidden. I'm accepting the defaults of the Find method.

Dim list As ListObject
Dim config As Worksheet
Dim cell as Range


Set config = Sheets("Config")
Set list = config.ListObjects("tblConfig")

'search in any cell of the data range of excel table
Set cell = list.DataBodyRange.Find(searchTerm)

If cell Is Nothing Then
    'when information is not found
Else
    'when information is found
End If

I use this:

function round(value, precision) {_x000D_
_x000D_
 if(precision == 0)_x000D_
  return Math.round(value);   _x000D_
_x000D_
 exp = 1;_x000D_
 for(i=0;i<precision;i++)_x000D_
  exp *= 10;_x000D_
_x000D_
 return Math.round(value*exp)/exp;_x000D_
}

I tried all the solutions and nothing worked. The following, however, does:

tr -cd '\11\12\15\40-\176'

Which I found here:

https://alvinalexander.com/blog/post/linux-unix/how-remove-non-printable-ascii-characters-file-unix

My problem needed it in a series of piped programs, not directly from a file, so modify as needed.

AFNetworking provides async image loading into a UIImageView with placeholder support. It also supports async networking for working with APIs in general.

Right click the project and click "Properties". Then select "Android" from the tree on the left. You can then select the target version on the right.

(Note as per the popular comment below, make sure your properties, classpath and project files are writable otherwise it won't work)

On linux : you can use ctrl + L or type command system clear.

• z means (un)z_ip.
• x means ex_tract files from the archive.
• v means print the filenames v_erbosely.
• f means the following argument is a f_ilename.

For more details, see tar's man page.

For this html:

<div class="outer">
     <div class="inner"></div>
</div>

This selector should work:

$('.outer > .inner')

A lot of things can configured in applicationproperties. Unfortunately this feature only in Version 1.3, but you can add in a Config-Class

@Autowired(required = true)
public void configureJackson(ObjectMapper jackson2ObjectMapper) {
    jackson2ObjectMapper.setSerializationInclusion(JsonInclude.Include.NON_NULL);
}

[UPDATE: You must work on the ObjectMapper because the build()-method is called before the config is runs.]

The data event is fired multiple times with 'chunks' of the body as they are downloaded and an end event when all chunks have been downloaded.

With Node supporting Promises now, I created a simple wrapper to return the concatenated chunks through a Promise:

const httpGet = url => {
  return new Promise((resolve, reject) => {
    http.get(url, res => {
      res.setEncoding('utf8');
      let body = ''; 
      res.on('data', chunk => body += chunk);
      res.on('end', () => resolve(body));
    }).on('error', reject);
  });
};

You can call it from an async function with:

const body = await httpGet('http://www.somesite.com');

<embed ... autostart="0">

Replace false with 0

If your string is

foo="US/Central - 10:26 PM (CST)"

then

echo "${foo}" | cut -d ' ' -f3

will do the job.

In my opinion the best approach to achieve this by using the filter method as it's meaningless to return in a forEach block; for an example on your snippet:

// Fetch all objects in SomeElements collection
var elementsCollection = SomeElements.find();
elementsCollection
.filter(function(element) {
  return element.shouldBeProcessed;
})
.forEach(function(element){
  doSomeLengthyOperation();
});

This will narrow down your elementsCollection and just keep the filtred elements that should be processed.

Also, make sure your branch is clean and there is nothing unstaged you can check with git status stash or commit the changes then run the comand

Vanilla JDBC only supports named parameters in a CallableStatement (e.g. setString("name", name)), and even then, I suspect the underlying stored procedure implementation has to support it.

An example of how to use named parameters:

//uss Sybase ASE sysobjects table...adjust for your RDBMS
stmt = conn.prepareCall("create procedure p1 (@id int = null, @name varchar(255) = null) as begin "
        + "if @id is not null "
        + "select * from sysobjects where id = @id "
        + "else if @name is not null "
        + "select * from sysobjects where name = @name "
        + " end");
stmt.execute();

//call the proc using one of the 2 optional params
stmt = conn.prepareCall("{call p1 ?}");
stmt.setInt("@id", 10);
ResultSet rs = stmt.executeQuery();
while (rs.next())
{
    System.out.println(rs.getString(1));
}


//use the other optional param
stmt = conn.prepareCall("{call p1 ?}");
stmt.setString("@name", "sysprocedures");
rs = stmt.executeQuery();
while (rs.next())
{
    System.out.println(rs.getString(1));
}

First, Examine XCode Preferences "Indentation" section. You can customize things quite a bit there...

For more fine grained control, refer to the XCode User Defaults document from apple. (May require a developer login to view). For example, I was able to disable the "indent on paste" by entering the following in terminal:

defaults write com.apple.XCODE PBXIndentOnPaste No

to read back your setting:

defaults read com.apple.XCODE PBXIndentOnPaste

Since the string "North" might be the beginning of a street name, e.g. "Northern Boulevard", street directions are always between the street number and the street name, and separated from street number and street name.

Public Function strReplace(varValue As Variant) as Variant

Select Case varValue

    Case "Avenue"
        strReplace = "Ave"

Run these Python3 codes to watch the need of finally:

CASE1:

count = 0
while True:
    count += 1
    if count > 3:
        break
    else:
        try:
            x = int(input("Enter your lock number here: "))

            if x == 586:
                print("Your lock has unlocked :)")

                break
            else:
                print("Try again!!")

                continue

        except:
            print("Invalid entry!!")
        finally:
            print("Your Attempts: {}".format(count))

CASE2:

count = 0

while True:
    count += 1
    if count > 3:
        break
    else:
        try:
            x = int(input("Enter your lock number here: "))

            if x == 586:
                print("Your lock has unlocked :)")

                break
            else:
                print("Try again!!")

                continue

        except:
            print("Invalid entry!!")

        print("Your Attempts: {}".format(count))

Try the following inputs each time:

1. random integers
2. correct code which is 586(Try this and you will get your answer)
3. random strings

** At a very early stage of learning Python.

Just uninstall whatever node version you have in your system. Then go to this site https://nodejs.org/download/release/ and choose your desired version like for me its like v7.0.0/ and click on that go get .msi file of that. Finally you will get installer in your system, so install it. It will solve all your problems.

There are so many ways to do it like

Dont add and href attribute

<a name="here"> Test <a>

You can add onclick event instead of href like

<a name="here" onclick="YourFunction()"> Test <a>

Or you can add void function like this which would be the best way

<a href="javascript:void(0);"> 
<a href="javascript:;">

Change the name of the .CSS file Load the page and then change the file again in the original name it works for me.

function pageLoad() is very dangerous to use in this situation. You could have events become wired multiple times. I would also stay away from .live() as it attaches to the document element and has to traverse the entire page (slow and crappy).

The best solution I have seen so far is to use jQuery .delegate() function on a wrapper outside the update panel and make use of bubbling. Other then that, you could always wire up the handlers using Microsoft's Ajax library which was designed to work with UpdatePanels.

Give them a class and add your style to the class.

<style>
  p {
    color: red;
  }
  .paragraph1 {
    font-size: 18px;
  }
  .paragraph2 {
    font-size: 13px;
  }
</style>

<p class="paragraph1">Paragraph 1</p>
<p class="paragraph2">Paragraph 2</p>

Check this EXAMPLE

AFAIS, nobody mentions of final usage for that. If you modify your last example and define variables a and b as final variables, then the compiler is assured that their sum, value 5 , can be assigned to a variable of type byte, without any loss of precision. In this case, the compiler is good to assign the sum of a and b to c . Here’s the modified code:

final byte a = 2;
final byte b = 3;
byte c = a + b;

Say you had some URL that gave you JSON data like:

{'field': 'value'}

...and you had a similar URL except it used JSONP, to which you passed the callback function name 'myCallback' (usually done by giving it a query parameter called 'callback', e.g. http://example.com/dataSource?callback=myCallback). Then it would return:

myCallback({'field':'value'})

...which is not just an object, but is actually code that can be executed. So if you define a function elsewhere in your page called myFunction and execute this script, it will be called with the data from the URL.

The cool thing about this is: you can create a script tag and use your URL (complete with callback parameter) as the src attribute, and the browser will run it. That means you can get around the 'same-origin' security policy (because browsers allow you to run script tags from sources other than the domain of the page).

This is what jQuery does when you make an ajax request (using .ajax with 'jsonp' as the value for the dataType property). E.g.

$.ajax({
  url: 'http://example.com/datasource',
  dataType: 'jsonp',
  success: function(data) {
    // your code to handle data here
  }
});

Here, jQuery takes care of the callback function name and query parameter - making the API identical to other ajax calls. But unlike other types of ajax requests, as mentioned, you're not restricted to getting data from the same origin as your page.

The message means that both the packages have functions with the same names. In this particular case, the testthat and assertive packages contain five functions with the same name.

When two functions have the same name, which one gets called?

R will look through the search path to find functions, and will use the first one that it finds.

search()
 ##  [1] ".GlobalEnv"        "package:assertive" "package:testthat" 
 ##  [4] "tools:rstudio"     "package:stats"     "package:graphics" 
 ##  [7] "package:grDevices" "package:utils"     "package:datasets" 
 ## [10] "package:methods"   "Autoloads"         "package:base"

In this case, since assertive was loaded after testthat, it appears earlier in the search path, so the functions in that package will be used.

is_true
## function (x, .xname = get_name_in_parent(x)) 
## {
##     x <- coerce_to(x, "logical", .xname)
##     call_and_name(function(x) {
##         ok <- x & !is.na(x)
##         set_cause(ok, ifelse(is.na(x), "missing", "false"))
##     }, x)
## }
<bytecode: 0x0000000004fc9f10>
<environment: namespace:assertive.base>

The functions in testthat are not accessible in the usual way; that is, they have been masked.

What if I want to use one of the masked functions?

You can explicitly provide a package name when you call a function, using the double colon operator, ::. For example:

testthat::is_true
## function () 
## {
##     function(x) expect_true(x)
## }
## <environment: namespace:testthat>

How do I suppress the message?

If you know about the function name clash, and don't want to see it again, you can suppress the message by passing warn.conflicts = FALSE to library.

library(testthat)
library(assertive, warn.conflicts = FALSE)
# No output this time

Alternatively, suppress the message with suppressPackageStartupMessages:

library(testthat)
suppressPackageStartupMessages(library(assertive))
# Also no output

Impact of R's Startup Procedures on Function Masking

If you have altered some of R's startup configuration options (see ?Startup) you may experience different function masking behavior than you might expect. The precise order that things happen as laid out in ?Startup should solve most mysteries.

For example, the documentation there says:

Note that when the site and user profile files are sourced only the base package is loaded, so objects in other packages need to be referred to by e.g. utils::dump.frames or after explicitly loading the package concerned.

Which implies that when 3rd party packages are loaded via files like .Rprofile you may see functions from those packages masked by those in default packages like stats, rather than the reverse, if you loaded the 3rd party package after R's startup procedure is complete.

How do I list all the masked functions?

First, get a character vector of all the environments on the search path. For convenience, we'll name each element of this vector with its own value.

library(dplyr)
envs <- search() %>% setNames(., .)

For each environment, get the exported functions (and other variables).

fns <- lapply(envs, ls)

Turn this into a data frame, for easy use with dplyr.

fns_by_env <- data_frame(
  env = rep.int(names(fns), lengths(fns)),
  fn  = unlist(fns)
)

Find cases where the object appears more than once.

fns_by_env %>% 
  group_by(fn) %>% 
  tally() %>% 
  filter(n > 1) %>% 
  inner_join(fns_by_env)

To test this, try loading some packages with known conflicts (e.g., Hmisc, AnnotationDbi).

How do I prevent name conflict bugs?

The conflicted package throws an error with a helpful error message, whenever you try to use a variable with an ambiguous name.

library(conflicted)
library(Hmisc)
units
## Error: units found in 2 packages. You must indicate which one you want with ::
##  * Hmisc::units
##  * base::units

I had two charts.

<div id="barChart"></div>
<div id="bubbleChart"></div>

This removed all charts.

d3.select("svg").remove(); 

This worked for removing the existing bar chart, but then I couldn't re-add the bar chart after

d3.select("#barChart").remove();

Tried this. It not only let me remove the existing bar chart, but also let me re-add a new bar chart.

d3.select("#barChart").select("svg").remove();

var svg = d3.select('#barChart')
       .append('svg')
       .attr('width', width + margins.left + margins.right)
       .attr('height', height + margins.top + margins.bottom)
       .append('g')
       .attr('transform', 'translate(' + margins.left + ',' + margins.top + ')');

Not sure if this is the correct way to remove, and re-add a chart in d3. It worked in Chrome, but have not tested in IE.

What @Bogdan Maxim said. Or change to use InProc if you're not using an external sesssion state server.

<sessionState mode="InProc" timeout="20" cookieless="AutoDetect" />

Look here for more info on the SessionState directive.

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

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

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

Then you can just do

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

or you can use a simple approach and just convert the string's case to substring's case and then use contains method.

You can use String unescapeJava(String) method of StringEscapeUtils from Apache Commons Lang.

Here's an example snippet:

    String in = "a\\tb\\n\\\"c\\\"";

    System.out.println(in);
    // a\tb\n\"c\"

    String out = StringEscapeUtils.unescapeJava(in);

    System.out.println(out);
    // a    b
    // "c"

The utility class has methods to escapes and unescape strings for Java, Java Script, HTML, XML, and SQL. It also has overloads that writes directly to a java.io.Writer.

Caveats

It looks like StringEscapeUtils handles Unicode escapes with one u, but not octal escapes, or Unicode escapes with extraneous us.

    /* Unicode escape test #1: PASS */
    
    System.out.println(
        "\u0030"
    ); // 0
    System.out.println(
        StringEscapeUtils.unescapeJava("\\u0030")
    ); // 0
    System.out.println(
        "\u0030".equals(StringEscapeUtils.unescapeJava("\\u0030"))
    ); // true
    
    /* Octal escape test: FAIL */
    
    System.out.println(
        "\45"
    ); // %
    System.out.println(
        StringEscapeUtils.unescapeJava("\\45")
    ); // 45
    System.out.println(
        "\45".equals(StringEscapeUtils.unescapeJava("\\45"))
    ); // false

    /* Unicode escape test #2: FAIL */
    
    System.out.println(
        "\uu0030"
    ); // 0
    System.out.println(
        StringEscapeUtils.unescapeJava("\\uu0030")
    ); // throws NestableRuntimeException:
       //   Unable to parse unicode value: u003

A quote from the JLS:

Octal escapes are provided for compatibility with C, but can express only Unicode values \u0000 through \u00FF, so Unicode escapes are usually preferred.

If your string can contain octal escapes, you may want to convert them to Unicode escapes first, or use another approach.

The extraneous u is also documented as follows:

The Java programming language specifies a standard way of transforming a program written in Unicode into ASCII that changes a program into a form that can be processed by ASCII-based tools. The transformation involves converting any Unicode escapes in the source text of the program to ASCII by adding an extra u-for example, \uxxxx becomes \uuxxxx-while simultaneously converting non-ASCII characters in the source text to Unicode escapes containing a single u each.

This transformed version is equally acceptable to a compiler for the Java programming language and represents the exact same program. The exact Unicode source can later be restored from this ASCII form by converting each escape sequence where multiple u's are present to a sequence of Unicode characters with one fewer u, while simultaneously converting each escape sequence with a single u to the corresponding single Unicode character.

If your string can contain Unicode escapes with extraneous u, then you may also need to preprocess this before using StringEscapeUtils.

Alternatively you can try to write your own Java string literal unescaper from scratch, making sure to follow the exact JLS specifications.

        if (card1.getRarity() < card2.getRarity()) {
            return 1;

However, if card2.getRarity() is less than card1.getRarity() you might not return -1.

You similarly miss other cases. I would do this, you can change around depending on your intent:

public int compareTo(Object o) {    
    if(this == o){
        return 0;
    }

    CollectionItem item = (CollectionItem) o;

    Card card1 = CardCache.getInstance().getCard(cardId);
    Card card2 = CardCache.getInstance().getCard(item.getCardId());
    int comp=card1.getSet() - card2.getSet();
    if (comp!=0){
        return comp;
    }
    comp=card1.getRarity() - card2.getRarity();
    if (comp!=0){
        return comp;
    }
    comp=card1.getSet() - card2.getSet();
    if (comp!=0){
        return comp;
    }   
    comp=card1.getId() - card2.getId();
    if (comp!=0){
        return comp;
    }   
    comp=card1.getCardType() - card2.getCardType();

    return comp;

    }
}

showInventory(player);     // I get the error here.

void showInventory(player& obj) {   // By Johnny :D

this means that player is an datatype and showInventory expect an referance to an variable of type player.

so the correct code will be

  void showInventory(player& obj) {   // By Johnny :D
    for(int i = 0; i < 20; i++) {
        std::cout << "\nINVENTORY:\n" + obj.getItem(i);
        i++;
        std::cout << "\t\t\t" + obj.getItem(i) + "\n";
        i++;
    }
    }

players myPlayers[10];

    std::string toDo() //BY KEATON

    std::string commands[5] =   // This is the valid list of commands.
        {"help", "inv"};

    std::string ans;
    std::cout << "\nWhat do you wish to do?\n>> ";

    if(ans == commands[0]) {

This should do what you want:

@Erik's answer didn't fly for me.

Following did:

 @Html.TextBoxFor(m => m.ShortName,  new { data_val_required = "You need me" })

plus doing this manually under field I had to add error message container

@Html.ValidationMessageFor(m => m.ShortName, null, new { @class = "field-validation-error", data_valmsg_for = "ShortName" })

The split-method of the string returns a list. A list in Python is very different from an array. == in this case does an element-wise comparison of the two lists and returns if all their elements are equal and the number and order of the elements is the same. Read the documentation.

I think you have an issue with your server certificate, is not a valid certificate (I think this is what "handshake_failure" means in this case):

Import your server certificate into your trustcacerts keystore on client's JRE. This is easily done with keytool:

    -alias <provide_an_alias>
    -file <certificate_file>
    -keystore <your_path_to_jre>/lib/security/cacerts

Here is an extension of Roberto14's answer that does the following:

THIS WILL ONLY ALLOW IMAGES

Checks if FileReader is available and falls back to extension checking if it is not available.

Gives an error alert if not an image

If it is an image it loads a preview

Yow can use querySelectorAll to select all the classes and loop through them to assign the eventListener. The if condition checks if it contains the class name.

const arrClass = document.querySelectorAll(".className");
for (let i of arrClass) {
  i.addEventListener("click", (e) => {
    if (e.target.classList.contains("className")) {
        console.log("Perfrom Action")
    }

Consider the figure enclosed in this other question. ebp-4 is your first local variable and, seen as a dword pointer, it is the address of a 32 bit integer that has to be cleared. Maybe your source starts with

Object x = null;

According to a quick google search, this update only applies to the current shell you have open. It can probably be fixed by typing python3, as mac and linux are similar enough for things like this to coincide. Link to the result of google search.

Also, as ninjagecko stated, most programs have not been updated to 3.x yet, so having the default python as 3.x would break many python scripts used in applications.

How about this?

http://jsfiddle.net/P7c9q/4/

<div class="relative">
  <div class="yellow-div"></div>
  <div class="yellow-div"></div>
  <div class="absolute"></div>
</div>

.relative{
position:relative;
}

.absolute {
position:absolute;
width: 40px;
height: 100px;
background: #000;
z-index: 1;
top:30px;
left:0px;
}
.yellow-div {
position:relative;
width: 200px;
height: 50px;
background: yellow;
margin-bottom:4px;
z-index:0;
}

use the relative div as wrapper and let the yellow div's have normal positioning.

Only the black block need to have an absolute position then.

It's as simple as that:

function isMacintosh() {
  return navigator.platform.indexOf('Mac') > -1
}

function isWindows() {
  return navigator.platform.indexOf('Win') > -1
}

You can do funny things then like:

var isMac = isMacintosh();
var isPC = !isMacintosh();

You could manually set the cookie, but depending on your use case (and if you might want to add more types of persistent/session data in future) it might make more sense to use Django's sessions feature. This will let you get and set variables tied internally to the user's session cookie. Cool thing about this is that if you want to store a lot of data tied to a user's session, storing it all in cookies will add a lot of weight to HTTP requests and responses. With sessions the session cookie is all that is sent back and forth (though there is the overhead on Django's end of storing the session data to keep in mind).

This is an old post, but it may help some people searching on this error to try setting "Enable 32-Bit Applications" to True for the app pool. That is what resolved the error for me. I came upon this solution by reading some the comments to @beckelmw's answer.

An element can have any number of classNames, however, it can only have one class attribute; only the first one will be read by jQuery.

Using the code you posted, $(".alert-box.warn") will work but $(".alert-box.dead") will not.

This is a complete implementation of Paul Bourdeaux's idea, namely returning a special initial view (or an empty view) in getView() for position 0.

It works for me and is relatively straightforward. You might consider this approach especially if you already have a custom adapter for your Spinner. (In my case, I was using custom adapter in order to easily customise the layout of the items, each item having a couple of TextViews.)

The adapter would be something along these lines:

public class MySpinnerAdapter extends ArrayAdapter<MyModel> {

    public MySpinnerAdapter(Context context, List<MyModel> items) {
        super(context, R.layout.my_spinner_row, items);
    }

    @Override
    public View getDropDownView(int position, View convertView, @NonNull ViewGroup parent) {
        if (position == 0) {
            return initialSelection(true);
        }
        return getCustomView(position, convertView, parent);
    }

    @NonNull
    @Override
    public View getView(int position, View convertView, @NonNull ViewGroup parent) {
        if (position == 0) {
            return initialSelection(false);
        }
        return getCustomView(position, convertView, parent);
    }


    @Override
    public int getCount() {
        return super.getCount() + 1; // Adjust for initial selection item
    }

    private View initialSelection(boolean dropdown) {
        // Just an example using a simple TextView. Create whatever default view 
        // to suit your needs, inflating a separate layout if it's cleaner.
        TextView view = new TextView(getContext());
        view.setText(R.string.select_one);
        int spacing = getContext().getResources().getDimensionPixelSize(R.dimen.spacing_smaller);
        view.setPadding(0, spacing, 0, spacing);

        if (dropdown) { // Hidden when the dropdown is opened
            view.setHeight(0);
        }

        return view;
    }

    private View getCustomView(int position, View convertView, ViewGroup parent) {
        // Distinguish "real" spinner items (that can be reused) from initial selection item
        View row = convertView != null && !(convertView instanceof TextView) 
        ? convertView :
        LayoutInflater.from(getContext()).inflate(R.layout.my_spinner_row, parent, false);

        position = position - 1; // Adjust for initial selection item
        MyModel item = getItem(position);

        // ... Resolve views & populate with data ...

        return row;
    }

}

That's it. Note that if you use a OnItemSelectedListener with your Spinner, in onItemSelected() you'd also have to adjust position to take the default item into account, for example:

if (position == 0) {
    return;
} else {
    position = position - 1;
}
MyModel selected = items.get(position);

If you use manual signing (which I would definitely encourage), this error may occur because Xcode thinks that it should sign a release build with a developer certificate, which is obviously not included in a release provisioning profile.

There is a build setting that defines which certificate should be used for which build configuration. To change it, go to build settings and search for Code Signing Identity. When expanded, there should be separate rows for each build configuration (usually Debug and Release) with in the second column its selected identity (usually iOS Developer or iOS Distribution). Make sure that it's set to the correct identity for each build configuration.

In some cases, the build configurations can also be expanded. Make sure that also its subitems are set to the correct identities.

Exe Application, first of all, references from a current directory to a subdirectory. And then, system directory. VS6.0 system directory was ..windows/system32. .NET system directory is like the below GAC path.

1. GAC path

   1) C:\Windows\Assembly (for .NET 2.0 ~ 3.5)

   2) C:\Windows\Microsoft.NET\assembly (for .NET 4.0)

2. How to install an assembly into GAC (as Administrator)

   1) Drag and Drop

   2) Use GacUtil.exe with Visual Studio Command Prompt

    gacutil -i [Path][Assembly Name].dll
   

   • Note: To install an assembly into the GAC, the assembly must be strongly named. Otherwise you get an error like this: Failure adding assembly to the cache: Attempt to install an assembly without a strong name.

3. How to uninstall an assembly from GAC (as Administrator)

    gacutil -u [Assembly Name], Version=1.0.0.0, PublickeyToken=7896a3567gh
   

   • Note: has no extention, .dll. Version and PublickeyToken can be omitted and be checked in GAC assembly.

The MySQL function LAST_INSERT_ID() does just what you need: it retrieves the id that was inserted during this session. So it is safe to use, even if there are other processes (other people calling the exact same script, for example) inserting values into the same table.

The PHP function mysql_insert_id() does the same as calling SELECT LAST_INSERT_ID() with mysql_query().

For Android device screen coordinates, below concept will work.

Display mdisp = getWindowManager().getDefaultDisplay();
Point mdispSize = new Point();
mdisp.getSize(mdispSize);
int maxX = mdispSize.x; 
int maxY = mdispSize.y;

EDIT:- ** **for devices supporting android api level older than 13. Can use below code.

    Display mdisp = getWindowManager().getDefaultDisplay();
    int maxX= mdisp.getWidth();
    int maxY= mdisp.getHeight();

(x,y) :-

1) (0,0) is top left corner.

2) (maxX,0) is top right corner

3) (0,maxY) is bottom left corner

4) (maxX,maxY) is bottom right corner

here maxX and maxY are screen maximum height and width in pixels, which we have retrieved in above given code.

Instead of:

void addStudent(person)
{
    return;
}

try this:

void addStudent(student person)
{
    return;
}

Since you have already declared a structure called 'student' you don't necessarily have to specify so in the function implementation as in:

void addStudent(struct student person)
{
    return;
}

From version 9.1.4 you only need to import ReactiveFormsModule

If you're processing a large amount of data (many megabytes) then you want to be using XmlReader to stream parse the XML.

Anything else (XPathNavigator, XElement, XmlDocument and even XmlSerializer if you keep the full generated object graph) will result in high memory usage and also a very slow load time.

Of course, if you need all the data in memory anyway, then you may not have much choice.

PHP foreach loop can be used with Indexed arrays, Associative arrays and Object public variables.

In foreach loop, the first thing php does is that it creates a copy of the array which is to be iterated over. PHP then iterates over this new copy of the array rather than the original one. This is demonstrated in the below example:

<?php
$numbers = [1,2,3,4,5,6,7,8,9]; # initial values for our array
echo '<pre>', print_r($numbers, true), '</pre>', '<hr />';
foreach($numbers as $index => $number){
    $numbers[$index] = $number + 1; # this is making changes to the origial array
    echo 'Inside of the array = ', $index, ': ', $number, '<br />'; # showing data from the copied array
}
echo '<hr />', '<pre>', print_r($numbers, true), '</pre>'; # shows the original values (also includes the newly added values).

Besides this, php does allow to use iterated values as a reference to the original array value as well. This is demonstrated below:

<?php
$numbers = [1,2,3,4,5,6,7,8,9];
echo '<pre>', print_r($numbers, true), '</pre>';
foreach($numbers as $index => &$number){
    ++$number; # we are incrementing the original value
    echo 'Inside of the array = ', $index, ': ', $number, '<br />'; # this is showing the original value
}
echo '<hr />';
echo '<pre>', print_r($numbers, true), '</pre>'; # we are again showing the original value

Note: It does not allow original array indexes to be used as references.

Can I see (...) the real SQL

If you want to see the SQL sent directly to the database (that is formatted similar to your example), you'll have to use some kind of jdbc driver proxy like P6Spy (or log4jdbc).

Alternatively you can enable logging of the following categories (using a log4j.properties file here):

log4j.logger.org.hibernate.SQL=DEBUG
log4j.logger.org.hibernate.type=TRACE

The first is equivalent to hibernate.show_sql=true, the second prints the bound parameters among other things.

  • 3.5. Logging
• Hibernate 4.1 Core Documentation
  • 4.1. Logging

this error usually shows if the name of your struct is different from the initialization of your struct in the code, so normally, c will find the name of the struct you put and if the original struct is not found, this would usually appear, or if you point a pointer pointed into that pointer, the error will show up.

You can also rename remote tags without checking them out, by duplicate the old tag/branch to a new name and delete the old one, in a single git push command.

Remote tag rename / Remote branch ? tag conversion: (Notice: :refs/tags/)

git push <remote_name> <old_branch_or_tag>:refs/tags/<new_tag> :<old_branch_or_tag>

Remote branch rename / Remote tag ? branch conversion: (Notice: :refs/heads/)

git push <remote_name> <old_branch_or_tag>:refs/heads/<new_branch> :<old_branch_or_tag>

Output renaming a remote tag:

D:\git.repo>git push gitlab App%2012.1%20v12.1.0.23:refs/tags/App_12.1_v12.1.0.23 :App%2012.1%20v12.1.0.23

Another technique that you can use to get the symbol from url gibberish is to open Chrome console with F12 and just paste following javascript:

decodeURIComponent("%2c")

it will decode and return the symbol (or symbols).

Hope this saves you some time.

Well, technically it's not possible to get :before and :after pseudo elements work on input elements

From W3C:

12.1 The :before and :after pseudo-elements

Authors specify the style and location of generated content with the :before and :after pseudo-elements. As their names indicate, the :before and :after pseudo-elements specify the location of content before and after an element's document tree content. The 'content' property, in conjunction with these pseudo-elements, specifies what is inserted.

So I had a project where I had submit buttons in the form of input tags and for some reason the other developers restricted me to use <button> tags instead of the usual input submit buttons, so I came up with another solution, of wrapping the buttons inside a span set to position: relative; and then absolutely positioning the icon using :after pseudo.

Note: The demo fiddle uses the content code for FontAwesome 3.2.1 so you may need to change the value of content property accordingly.

HTML

<span><input type="submit" value="Send" class="btn btn-default" /></span>

CSS

input[type="submit"] {
    margin: 10px;
    padding-right: 30px;
}

span {
    position: relative;
}

span:after {
    font-family: FontAwesome;
    content: "\f004"; /* Value may need to be changed in newer version of font awesome*/
    font-size: 13px;
    position: absolute;
    right: 20px;
    top: 1px;
    pointer-events: none;
}

Demo

Now here everything is self explanatory here, about one property i.e pointer-events: none;, I've used that because on hovering over the :after pseudo generated content, your button won't click, so using the value of none will force the click action to go pass through that content.

From Mozilla Developer Network :

In addition to indicating that the element is not the target of mouse events, the value none instructs the mouse event to go "through" the element and target whatever is "underneath" that element instead.

Hover the heart font/icon Demo and see what happens if you DON'T use pointer-events: none;

$timestamp = strtotime($row['DATETIMEAPP']);

gives you timestamp, which then you can use date to format:

$date = date('d-m-Y', $timestamp);
$time = date('Gi.s', $timestamp);

Alternatively

list($date, $time) = explode('|', date('d-m-Y|Gi.s', $timestamp));

You can try

document.getElementById("textboxid").readOnly = true;

Over time, I have found that extracting text from PDFs in a structured format is tough business. However if you are looking for an easy solution, you might want to consider XPDF tool pdftotext.

Pseudocode to extract the text would include:

1. Using SHELL VBA statement to extract the text from PDF to a temporary file using XPDF
2. Using sequential file read statements to read the temporary file contents into a string
3. Pasting the string into Excel

Simplified example below:

    Sub ReadIntoExcel(PDFName As String)
        'Convert PDF to text
        Shell "C:\Utils\pdftotext.exe -layout " & PDFName & " tempfile.txt"

        'Read in the text file and write to Excel
        Dim TextLine as String
        Dim RowNumber as Integer
        Dim F1 as Integer
        RowNumber = 1
        F1 = Freefile()
        Open "tempfile.txt" for Input as #F1
            While Not EOF(#F1)
                Line Input #F1, TextLine
                ThisWorkbook.WorkSheets(1).Cells(RowNumber, 1).Value = TextLine
                RowNumber = RowNumber + 1
            Wend
        Close #F1
    End Sub

i'd like to suggest my approach. First, separate grouping and aggregating. Lets declare prototypical "group by" function. It takes another function to produce "hash" string for each array element to group by.

Array.prototype.groupBy = function(hash){
  var _hash = hash ? hash : function(o){return o;};

  var _map = {};
  var put = function(map, key, value){
    if (!map[_hash(key)]) {
        map[_hash(key)] = {};
        map[_hash(key)].group = [];
        map[_hash(key)].key = key;

    }
    map[_hash(key)].group.push(value); 
  }

  this.map(function(obj){
    put(_map, obj, obj);
  });

  return Object.keys(_map).map(function(key){
    return {key: _map[key].key, group: _map[key].group};
  });
}

when grouping is done you can aggregate data how you need, in your case

data.groupBy(function(o){return JSON.stringify({a: o.Phase, b: o.Step});})
    /* aggreagating */
    .map(function(el){ 
         var sum = el.group.reduce(
           function(l,c){
             return l + parseInt(c.Value);
           },
           0
         );
         el.key.Value = sum; 
         return el.key;
    });

in common it works. i have tested this code in chrome console. and feel free to improve and find mistakes ;)

From Effective Go:

Constants in Go are just that—constant. They are created at compile time, even when defined as locals in functions, and can only be numbers, characters (runes), strings or booleans. Because of the compile-time restriction, the expressions that define them must be constant expressions, evaluatable by the compiler. For instance, 1<<3 is a constant expression, while math.Sin(math.Pi/4) is not because the function call to math.Sin needs to happen at run time.

Slices and arrays are always evaluated during runtime:

var TestSlice = []float32 {.03, .02}
var TestArray = [2]float32 {.03, .02}
var TestArray2 = [...]float32 {.03, .02}

[...] tells the compiler to figure out the length of the array itself. Slices wrap arrays and are easier to work with in most cases. Instead of using constants, just make the variables unaccessible to other packages by using a lower case first letter:

var ThisIsPublic = [2]float32 {.03, .02}
var thisIsPrivate = [2]float32 {.03, .02}

thisIsPrivate is available only in the package it is defined. If you need read access from outside, you can write a simple getter function (see Getters in golang).

I just added an @ symbol and it started working. Like this: @$product->save();

Using API version 2, which is deprecated, the URL for uploads (of channel UCqAEtEr0A0Eo2IVcuWBfB9g) is:

There is an API version 3.

group by default order by pk id,so the result
username point avg_time
demo123 100 90 ---> id = 4
demo123456 100 100 ---> id = 7
demo 90 120 ---> id = 1

In addition to:

myFilePath = replace(myFilePath, "/", "\")
myFilePath = replace(myFilePath, "http:", "")

also replace space:

myFilePath = replace(myFilePath, " ", "%20")

If you want to install dependencies from a requirements file within a CI server or alike, you can do this:

git config --global credential.helper 'cache'
echo "protocol=https
host=example.com
username=${GIT_USER}
password=${GIT_PASS}
" | git credential approve
pip install -r requirements.txt

In my case, I used GIT_USER=gitlab-ci-token and GIT_PASS=${CI_JOB_TOKEN}.

This method has a clear advantage. You have a single requirements file which contains all of your dependencies.

I have great news: this will be in Compose 1.3!

I'm using it in the current RC (RC1) like this:

rng:
  build: rng
  extra_hosts:
    seed: 1.2.3.4
    tree: 4.3.2.1

Try these

 String appDirectoryName = getResources().getString(R.string.app_name);
    File directory = new File(Environment.getExternalStorageDirectory().getAbsolutePath() + "/" + getResources().getString(R.string.app_name));
    directory.mkdirs();
    File[] fList = directory.listFiles();
    int a = 1;
    for (int x = 0; x < fList.length; x++) {

        //txt.setText("You Have Capture " + String.valueOf(a) + " Photos");
        a++;
    }
    //get all the files from a directory
    for (File file : fList) {
        if (file.isFile()) {
            list.add(new ModelClass(file.getName(), file.getAbsolutePath()));
        }
    }

val() should handle both cases

  <option value="1">it's me</option>      


$('select').val('1'); // selects "it's me"

$('select').val("it's me"); // also selects "it's me"

As stated in the Laravel manual, you may roll back specific number of migrations using the --step option

From there if you need any more info you can just look up the object / line number.

Try

string reversed(temp.rbegin(), temp.rend());

EDIT: Elaborating as requested.

string::rbegin() and string::rend(), which stand for "reverse begin" and "reverse end" respectively, return reverse iterators into the string. These are objects supporting the standard iterator interface (operator* to dereference to an element, i.e. a character of the string, and operator++ to advance to the "next" element), such that rbegin() points to the last character of the string, rend() points to the first one, and advancing the iterator moves it to the previous character (this is what makes it a reverse iterator).

Finally, the constructor we are passing these iterators into is a string constructor of the form:

template <typename Iterator>
string(Iterator first, Iterator last);

which accepts a pair of iterators of any type denoting a range of characters, and initializes the string to that range of characters.

I'd almost never store them in the DB. The best approach is usually to store your images in a path controlled by a central configuration variable and name the images according to the DB table and primary key (if possible). This gives you the following advantages:

• Move your images to another partition or server just by updating the global config.
• Find the record matching the image by searching on its primary key.
• Your images are accessable to processing tools like imagemagick.
• In web-apps your images can be handled by your webserver directly (saving processing).
• CMS tools and web languages like Coldfusion can handle uploading natively.

In typescript it is possible to do an instanceof check in an if statement and you will have access to the same variable with the Typed properties.

So let's say MarkerSymbolInfo has a property on it called marker. You can do the following:

if (symbolInfo instanceof MarkerSymbol) {
    // access .marker here
    const marker = symbolInfo.marker
}

It's a nice little trick to get the instance of a variable using the same variable without needing to reassign it to a different variable name.

Check out these two resources for more information:

TypeScript instanceof & JavaScript instanceof

def factorial(n):
    if n < 2:
        return 1
    return n * factorial(n - 1)

A solution that I like, because it keeps rspec output separate from actual rails log output, is to do the following:

• Open a second terminal window or tab, and arrange it so that you can see both the main terminal you're running rspec on as well as the new one.
• Run a tail command in the second window so you see the rails log in the test environment. By default this can be like $ tail -f $RAILS_APP_DIR/logs/test.log or tail -f $RAILS_APP_DIR\logs\test.log for Window users
• Run your rspec suites

If you are running a multi-pane terminal like iTerm, this becomes even more fun and you have rspec and the test.log output side by side.

For future reference, you can get help for any command by using the /? switch, which should explain what switches do what.

According to the set /? screen, the format for set /p is SET /P variable=[promptString] which would indicate that the p in /p is "prompt." It just prints in your example because <nul passes in a nul character which immediately ends the prompt so it just acts like it's printing. It's still technically prompting for input, it's just immediately receiving it.

/L in for /L generates a List of numbers.

A bit of encoding can solve this:

Client Side:

message = input("->")
clientSocket.sendto(message.encode('utf-8'), (address, port))

Server Side:

data = s.recv(1024)
modifiedMessage, serverAddress = clientSocket.recvfrom(message.decode('utf-8'))

You can also set the options --log-fd if you just want to read your logs with a less. For example :

valgrind --log-fd=1 ls | less

Try this

$('#testID').addClass('nameOfClass');

or

$('#testID').removeClass('nameOfClass');

 date('Y-m-d',(strtotime ( '-1 day' , strtotime ( $date) ) ));

You can also add column to a specific position using before column or after column like:

rails generate migration add_dob_to_customer dob:date

The migration file will generate the following code except after: :email. you need to add after: :email or before: :email

class AddDobToCustomer < ActiveRecord::Migration[5.2]
  def change
    add_column :customers, :dob, :date, after: :email
  end
end

While it may work on some platforms, be aware that platform.architecture is not always a reliable way to determine whether python is running in 32-bit or 64-bit. In particular, on some OS X multi-architecture builds, the same executable file may be capable of running in either mode, as the example below demonstrates. The quickest safe multi-platform approach is to test sys.maxsize on Python 2.6, 2.7, Python 3.x.

$ arch -i386 /usr/local/bin/python2.7

Screenshot:

1. Using BoxShadow (more customizations):

   Container(
     width: 100,
     height: 100,
     decoration: BoxDecoration(
       color: Colors.teal,
       borderRadius: BorderRadius.circular(20),
       boxShadow: [
         BoxShadow(
           color: Colors.red,
           blurRadius: 4,
           offset: Offset(4, 8), // Shadow position
         ),
       ],
     ),
   )
   

2. Using PhysicalModel:

   PhysicalModel(
     color: Colors.teal,
     elevation: 8,
     shadowColor: Colors.red,
     borderRadius: BorderRadius.circular(20),
     child: SizedBox(width: 100, height: 100),
   )
   

datetime.time can not do it - But you could use datetime.datetime.now()

start = datetime.datetime.now()
sleep(10)
end = datetime.datetime.now()
duration = end - start

If you want to truncate by a number of words and add an ellipsis you can use this function:

truncate(value: string, limit: number = 40, trail: String = '…'): string {
  let result = value || '';

  if (value) {
    const words = value.split(/\s+/);
    if (words.length > Math.abs(limit)) {
      if (limit < 0) {
        limit *= -1;
        result = trail + words.slice(words.length - limit, words.length).join(' ');
      } else {
        result = words.slice(0, limit).join(' ') + trail;
      }
    }
  }

  return result;
}

Example:

truncate('Bacon ipsum dolor amet sirloin tri-tip swine', 5, '…')
> "Bacon ipsum dolor amet sirloin…"

taken from: https://github.com/yellowspot/ng2-truncate/blob/master/src/truncate-words.pipe.ts

If you want to truncate by a number of letters but don't cut words out use this:

truncate(value: string, limit = 25, completeWords = true, ellipsis = '…') {
  let lastindex = limit;
  if (completeWords) {
    lastindex = value.substr(0, limit).lastIndexOf(' ');
  }
  return `${value.substr(0, limit)}${ellipsis}`;
}

Example:

truncate('Bacon ipsum dolor amet sirloin tri-tip swine', 19, true, '…')
> "Bacon ipsum dolor…"

truncate('Bacon ipsum dolor amet sirloin tri-tip swine', 19, false, '…')
> "Bacon ipsum dolor a…"

Try this for multiple CSS styles:

$(this).css({
    "background-color": 'red',
    "color" : "white"
});

check the postgres server is running with following code

sudo service postgresql status

if the postgres server is inactive, write the following command.

sudo service postgresql start

Well, data.str().c_str() yields a char const* but your function Printfunc() wants to have char*s. Based on the name, it doesn't change the arguments but merely prints them and/or uses them to name a file, in which case you should probably fix your declaration to be

void Printfunc(int a, char const* loc, char const* stream)

The alternative might be to turn the char const* into a char* but fixing the declaration is preferable:

Printfunc(num, addr, const_cast<char*>(data.str().c_str()));

If you are interested in parsing command line arguments to an R script try RScript which is bundled with R as of version 2.5.x

                ]
            )
            ->get();

Remember the group by is optional,this should work in most cases when you want a count group by to exclude duplicated select values, the addSelect is a querybuilder instance method.

If you're having problems with phpize not found on CentOS7.x after you have installed the relevant devel tools for your version/s of PHP, this path finally worked for me:

For PHP 7.2.x

/opt/cpanel/ea-php72/root/usr/bin/phpize

For PHP 7.3.x

/opt/cpanel/ea-php73/root/usr/bin/phpize

For PHP 7.4.x

/opt/cpanel/ea-php74/root/usr/bin/phpize

Run this in your folder containing the downloaded PHP extension, for example in line 3 below:

Example based on installing the PHP v7.3.x Brotli Extension from https://github.com/kjdev/php-ext-brotli

git clone --recursive --depth=1 https://github.com/kjdev/php-ext-brotli.git
cd /php-ext-brotli

"For servers with more than one IP address, this attribute specifies which address will be used for listening on the specified port. By default, this port will be used on all IP addresses associated with the server."

Android Studio (Preview) sometimes recommends updating to a Gradle Plugin that is not available yet (did Google forget to publish it?). Such as today with

'com.android.tools.build:gradle:3.1.0-beta1'

I found I can see current versions of com.android.tools.build:gradle here, and then I just pick the newest:

https://dl.google.com/dl/android/maven2/index.html

I just found this beta1 gradle bug in the Android Bug Tracker. I also just learned Android Studio > Help Menu > Submit Feedback brought me to the bug tracker.

Found temporary solution at androiddev reddit for the 3.1.0-beta1 problem: Either roll back to Preview Canary 8, or switch to gradle plugin 3.0.1 until Canary 10 is released shortly.

#include<stdio.h>

while (*ptr) { // While there are more characters to process...
    if ( isdigit(*ptr) ) {
        // Found a number
        int val = (int)strtol(ptr,&ptr, 10); // Read number
        printf("%d\n", val); // and print it.
    } else {
        // Otherwise, move on to the next character.
        ptr++;
    }
}

}

Try this,

Use the code below as a reference to check a single item in RecyclerView:

public class SampleAdapter extends RecyclerView.Adapter<SampleAdapter.ViewHolder> {

    private final String[] list;
    private int lastCheckedPosition = -1;

    public SampleAdapter(String[] list) {
        this.list = list;
    }

    @Override
    public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View view = View.inflate(parent.getContext(), R.layout.sample_layout, null);
        ViewHolder holder = new ViewHolder(view);
        return holder;
    }

    @Override
    public void onBindViewHolder(ViewHolder holder, int position) {
        holder.choiceName.setText(list[position]);
        holder.radioButton.setChecked(position == lastCheckedPosition);
    }

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

    public class ViewHolder extends RecyclerView.ViewHolder {
        @Bind(R.id.choice_name)
        TextView choiceName;
        @Bind(R.id.choice_select)
        RadioButton radioButton;

        public ViewHolder(View itemView) {

                public void onClick(View v) {
                    int copyOfLastCheckedPosition = lastCheckedPosition;
            lastCheckedPosition = getAdapterPosition();
            notifyItemChanged(copyOfLastCheckedPosition);
            notifyItemChanged(lastCheckedPosition);

                }

        }
    }
}

It is rare, in reality, that you would want to use an array. Definitely use a List<T> any time you want to add/remove data, since resizing arrays is expensive. If you know the data is fixed length, and you want to micro-optimise for some very specific reason (after benchmarking), then an array may be useful.

List<T> offers a lot more functionality than an array (although LINQ evens it up a bit), and is almost always the right choice. Except for params arguments, of course. ;-p

As a counter - List<T> is one-dimensional; where-as you have have rectangular (etc) arrays like int[,] or string[,,] - but there are other ways of modelling such data (if you need) in an object model.

See also:

• How/When to abandon the use of Arrays in c#.net?
• Arrays, What's the point?

That said, I make a lot of use of arrays in my protobuf-net project; entirely for performance:

• it does a lot of bit-shifting, so a byte[] is pretty much essential for encoding;
• I use a local rolling byte[] buffer which I fill before sending down to the underlying stream (and v.v.); quicker than BufferedStream etc;
• it internally uses an array-based model of objects (Foo[] rather than List<Foo>), since the size is fixed once built, and needs to be very fast.

But this is definitely an exception; for general line-of-business processing, a List<T> wins every time.

<?php

$xml = $argv[1];

$dom = new DOMDocument();

// Initial block (must before load xml string)
$dom->preserveWhiteSpace = false;
$dom->formatOutput = true;
// End initial block

$dom->loadXML($xml);
$out = $dom->saveXML();

print_R($out);

This will work everywhere.

<body>
  <table style="table-layout:fixed;">
  <tr>
    <td><div style="word-wrap: break-word; width: 100px" > gdfggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggg</div></td>
  </tr>
  </table>
 </body>

You can now use _.reject which allows you to filter based on what you need to get rid of, instead of what you need to keep.

unlike _.pull or _.remove that only work on arrays, ._reject is working on any Collection

obj.subTopics = _.reject(obj.subTopics, (o) => {
  return o.number >= 32;
});

I use one of the following two ways for this check:

1: View config.json file:

In case you are logged in to "private.registry.com" you will see an entry for the same as following in ~/.docker/config.json:

"auths": {
    "private.registry.com": {
        "auth": "gibberishgibberishgibberishgibberishgibberishgibberish"
    }
 }

2: Try docker login once again:

If you are trying to see if you already have an active session with private.registry.com, try to login again:

bash$ docker login private.registry.com
Username (logged-in-user):

If you get an output like the above, it means logged-in-user already had an active session with private.registry.com. If you are just prompted for username instead, that would indicate that there's no active session.

For some applications may be better:

string.Join(",", arr1) == string.Join(",", arr2)

There is another important difference between select and datalist. Here comes the browser support factor.

select is widely supported by browsers compared to datalist. Please take a look at this page for complete browser support of datalist--

Datalist browser support

Where as select is supported in effectively all browsers (since IE6+, Firefox 2+, Chrome 1+ etc)

This question has been answered already several times, I'll short summary for each of them, an example and insights as of September 2019:

• Normalize.css - as the name suggests, it normalizes styles in the browsers for their user agents, i.e. makes them the same across all browsers due to the reason by default they're slightly different.

Example: <h1> tag inside <section> by default Google Chrome will make smaller than the "expected" size of <h1> tag. Microsoft Edge on the other hand is making the "expected" size of <h1> tag. Normalize.css will make it consistent.

Current status: the npm repository shows that normalize.css package has currently more than 500k downloads per week. GitHub stars in the project of the repository are more than 36k.

• Reset CSS - as the name suggests, it resets all styles, i.e. it removes all browser's user agent styles.

Example: it would do something like that below:

html, body, div, span, ..., audio, video {  
   margin: 0;  
   padding: 0;  
   border: 0;  
   font-size: 100%;  
   font: inherit;  
   vertical-align: baseline; 
}

Current status: it's much less popular than Normalize.css, the reset-css package shows it's something around 26k downloads per week. GitHub stars are only 200, as it can be noticed from the project's repository.

• Assumption 1: You're attempting to convert a date to a timestamp, however since a date covers a 24 hour period, there isn't a single timestamp that represents that date. I'll assume that you want to represent the timestamp of that date at midnight (00:00:00.000).

• Assumption 2: The date you present is not associated with a particular time zone, however you want to determine the offset from a particular time zone (UTC). Without knowing the time zone the date is in, it isn't possible to calculate a timestamp for a specific time zone. I'll assume that you want to treat the date as if it is in the local system time zone.

First, you can convert the date instance into a tuple representing the various time components using the timetuple() member:

dtt = d.timetuple() # time.struct_time(tm_year=2011, tm_mon=1, tm_mday=1, tm_hour=0, tm_min=0, tm_sec=0, tm_wday=5, tm_yday=1, tm_isdst=-1)

You can then convert that into a timestamp using time.mktime:

ts = time.mktime(dtt) # 1293868800.0

You can verify this method by testing it with the epoch time itself (1970-01-01), in which case the function should return the timezone offset for the local time zone on that date:

d = datetime.date(1970,1,1)
dtt = d.timetuple() # time.struct_time(tm_year=1970, tm_mon=1, tm_mday=1, tm_hour=0, tm_min=0, tm_sec=0, tm_wday=3, tm_yday=1, tm_isdst=-1)
ts = time.mktime(dtt) # 28800.0

28800.0 is 8 hours, which would be correct for the Pacific time zone (where I'm at).

Use the Figure.savefig() method, like so:

ax = s.hist()  # s is an instance of Series
fig = ax.get_figure()
fig.savefig('/path/to/figure.pdf')

It doesn't have to end in pdf, there are many options. Check out the documentation.

Alternatively, you can use the pyplot interface and just call the savefig as a function to save the most recently created figure:

import matplotlib.pyplot as plt
s.hist()
plt.savefig('path/to/figure.pdf')  # saves the current figure

Based on @Dave Syer, @kaliatech and @asmaier answers the springboot v2+ way would be:

@Configuration
@AutoConfigureAfter(DispatcherServletAutoConfiguration.class)
public class StaticResourceConfiguration implements WebMvcConfigurer  {

  @Override
  public void addResourceHandlers(ResourceHandlerRegistry registry) {
    String myExternalFilePath = "file:///C:/temp/whatever/m/";

     registry.addResourceHandler("/m/**").addResourceLocations(myExternalFilePath);

  }

}

Use the CKEditor method setData():

CKEDITOR.instances[**fieldname**].setData(**your data**)

You can just use wildcards in the predicate (after IF, WHERE or ON):

@mainstring LIKE '%' + @substring + '%'

or in this specific case

' ' + @mainstring + ' ' LIKE '% ME[., ]%'

(Put the spaces in the quoted string if you're looking for the whole word, or leave them out if ME can be part of a bigger word).

If boolean() is not available (the tool I'm using does not) one way to achieve it is:

//SELECT[@id='xpto']/OPTION[not(not(@selected))]

In this case, within the /OPTION, one of the options is the selected one. The "selected" does not have a value... it just exists, while the other OPTION do not have "selected". This achieves the objective.

pthread_self() function will give the thread id of current thread.

pthread_t pthread_self(void);

The pthread_self() function returns the Pthread handle of the calling thread. The pthread_self() function does NOT return the integral thread of the calling thread. You must use pthread_getthreadid_np() to return an integral identifier for the thread.

NOTE:

pthread_id_np_t   tid;
tid = pthread_getthreadid_np();

is significantly faster than these calls, but provides the same behavior.

pthread_id_np_t   tid;
pthread_t         self;
self = pthread_self();
pthread_getunique_np(&self, &tid);

I had a new VirtualHost configuration file that was not showing when using the apachectl -S command. After much head scratching I realised that my file did not have suffix ".conf". Once I renamed the file with that suffix my Vhost started showing and working!

I think that you are after this:

SELECT image_id
FROM list
WHERE (style_id, style_value) IN ((24,'red'),(25,'big'),(27,'round'))
GROUP BY image_id
HAVING count(distinct style_id, style_value)=3

You can't use AND, because values can't be 24 red and 25 big and 27 round at the same time in the same row, but you need to check the presence of style_id, style_value in multiple rows, under the same image_id.

In this query I'm using IN (that, in this particular example, is equivalent to an OR), and I am counting the distinct rows that match. If 3 distinct rows match, it means that all 3 attributes are present for that image_id, and my query will return it.

Use CSS styles with CSS Classes instead

CSS

.error {
  border:2px solid red;
}

Now in Javascript

document.getElementById("fName").className = document.getElementById("fName").className + " error";  // this adds the error class

document.getElementById("fName").className = document.getElementById("fName").className.replace(" error", ""); // this removes the error class

The main reason I mention this is suppose you want to change the color of the errored element's border. If you choose your way you will may need to modify many places in code. If you choose my way you can simply edit the style sheet.

I was getting the same error. For Java version 7, following is working for me.

java.lang.System.setProperty("https.protocols", "TLSv1.2");

I assume that you've run yum upgrade. That will in general update you to the newest minor release.

Your main resources for determining the version are /etc/redhat_release and lsb_release -a

It seems System.gc() do not work on Art Android 6.0.1 Nexus 5x, So I use Runtime.getRuntime().gc(); instead.

In python, bool(sequence) is False if the sequence is empty. Since strings are sequences, this will work:

cookie = ''
if cookie:
    print "Don't see this"
else:
    print "You'll see this"

A predicate is a function that returns a true/false (i.e. boolean) value, as opposed to a proposition which is a true/false (i.e. boolean) value. In Java, one cannot have standalone functions, and so one creates a predicate by creating an interface for an object that represents a predicate and then one provides a class that implements that interface. An example of an interface for a predicate might be:

public interface Predicate<ARGTYPE>
{
    public boolean evaluate(ARGTYPE arg);
}

And then you might have an implementation such as:

public class Tautology<E> implements Predicate<E>
{
     public boolean evaluate(E arg){
         return true;
     }
}

To get a better conceptual understanding, you might want to read about first-order logic.

Edit
There is a standard Predicate interface (java.util.function.Predicate) defined in the Java API as of Java 8. Prior to Java 8, you may find it convenient to reuse the com.google.common.base.Predicate interface from Guava.

Also, note that as of Java 8, it is much simpler to write predicates by using lambdas. For example, in Java 8 and higher, one can pass p -> true to a function instead of defining a named Tautology subclass like the above.

In my case, I was calling a delegate method but the method wasn't declared.

This error is generic and can appear by a number of reasons. Make sure you have not disabled your Logs to actually see what happened. Enable OS_ACTIVITY_MODE in the schemes if you have disabled it. You might have disabled it to prevent a lot of irrelevant logs but they are handy.

You can also trace the cause in more details by adding an exception breakpoint po $arg1. As already mentioned by Ahmed-Lotfi

Here is a common checklist that you can go through.

2) Check if you have renamed an IBOutlet and calling it
3) Check if you have renamed a method name or the method doesn't exist
4) Check if you are trying to add or remove any view from hierarchy
5) Check for any missing framework or library
6) Check if you’ve forgot to register your custom cell identifier
7) Check for any missing flag in the Proejct Setting (-obj) or any other linker flag etc.

Set the following two environment variables:

NVIDIA_VISIBLE_DEVICES=$gpu_id
CUDA_VISIBLE_DEVICES=0

where gpu_id is the ID of your selected GPU, as seen in the host system's nvidia-smi (a 0-based integer) that will be made available to the guest system (e.g. to the Docker container environment).

You can verify that a different card is selected for each value of gpu_id by inspecting Bus-Id parameter in nvidia-smi run in a terminal in the guest system).

More info

This method based on NVIDIA_VISIBLE_DEVICES exposes only a single card to the system (with local ID zero), hence we also hard-code the other variable, CUDA_VISIBLE_DEVICES to 0 (mainly to prevent it from defaulting to an empty string that would indicate no GPU).

Note that the environmental variable should be set before the guest system is started (so no chances of doing it in your Jupyter Notebook's terminal), for instance using docker run -e NVIDIA_VISIBLE_DEVICES=0 or env in Kubernetes or Openshift.

If you want GPU load-balancing, make gpu_id random at each guest system start.

If setting this with python, make sure you are using strings for all environment variables, including numerical ones.

You can verify that a different card is selected for each value of gpu_id by inspecting nvidia-smi's Bus-Id parameter (in a terminal run in the guest system).

The accepted solution based on CUDA_VISIBLE_DEVICES alone does not hide other cards (different from the pinned one), and thus causes access errors if you try to use them in your GPU-enabled python packages. With this solution, other cards are not visible to the guest system, but other users still can access them and share their computing power on an equal basis, just like with CPU's (verified).

This is also preferable to solutions using Kubernetes / Openshift controlers (resources.limits.nvidia.com/gpu), that would impose a lock on the allocated card, removing it from the pool of available resources (so the number of containers with GPU access could not exceed the number of physical cards).

This has been tested under CUDA 8.0, 9.0 and 10.1 in docker containers running Ubuntu 18.04 orchestrated by Openshift 3.11.

No, that's pretty much it. In theory you could use visibility: collapse on some <col>?s to do it, but browser support isn't all there.

To improve what you've got slightly, you could use table-layout: fixed on the <table> to allow the browser to use the simpler, faster and more predictable fixed-table-layout algorithm. You could also drop the .show rules as when a cell isn't made display: none by a .hide rule it will automatically be display: table-cell. Allowing table display to revert to default rather than setting it explicitly avoids problems in IE<8, where the table display values are not supported.

Use the Insert method:

ti.Insert(0, initialItem);

If you have anaconda install than you just need to use command: conda install PyAudio.

In order to execute this command you must set thePYTHONPATH environment variable in anaconda.

Use

git cherry-pick <commit>

to apply <commit> to your current branch.

I myself would probably cross-check the commits I pick in gitk and cherry-pick them with right-clicks on the commit entry there instead.

If you want to go more automatic (with all its dangers) and assuming all commits since yesterday happened on wss you could generate the list of commits using git log (with --pretty suggested by Jefromi)

git log --reverse --since=yesterday --pretty=%H

so everything together assuming you use bash

for commit in $(git log --reverse --since=yesterday --pretty=%H);
do
    git cherry-pick $commit
done

If something goes wrong here (there is a lot of potential) you are in trouble since this works on the live checkout, so either do manual cherry-picks or use rebase like suggested by Jefromi.

>>> dict([('A', 1), ('B', 2), ('C', 3)])
{'A': 1, 'C': 3, 'B': 2}

getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE);

This one is working for me.

Addition:

When using the MySQL client library, then you should prevent a conversion back to your connection's default charset. (see mysql_set_character_set()[1])

In this case, use an additional cast to binary:

SELECT column1, CAST(CONVERT(column2 USING utf8) AS binary)
FROM my_table
WHERE my_condition;

Otherwise, the SELECT statement converts to utf-8, but your client library converts it back to a (potentially different) default connection charset.

In my case it worked great just by doing the following:

The Controller:

[HttpPost]
public ActionResult DoSomething(int custNum)
{
    // Some magic code here...
}

Create the form with no action:

<form id="frmSomething" method="post">
    <div>
        <!-- Some magic html here... -->
    </div>
    <button id="btnSubmit" type="submit">Submit</button>
</form>

Set button click event to trigger submit after adding the action to the form:

var frmSomething= $("#frmSomething");
var btnSubmit= $("#btnSubmit");
var custNum = 100;

btnSubmit.click(function()
    {
        frmSomething.attr("action", "/Home/DoSomething?custNum=" + custNum);

        btnSubmit.submit();
    });

Hope this helps vatos!

Here's a nice little global function you can add for a nicer syntax:

func dispatch_on_main(block: dispatch_block_t) {
    dispatch_async(dispatch_get_main_queue(), block)
}

And usage

dispatch_on_main {
    // Do some UI stuff
}

Just activate the curl in the php.ini file

;extension=php_curl.dll

to

extension=php_curl.dll

and then composer install

Another solution I ran across tonight, which worked for my needs, was to add box-sizing attributes:

-webkit-box-sizing: border-box;
-moz-box-sizing: border-box;
box-sizing: border-box;

These attributes force the border to be part of the box model's width and height and correct the issue as well.

According to caniuse.com » box-sizing, box-sizing is supported in IE8+.

If you're using LESS or Sass there is a Bootstrap mixin for this.

LESS:

.box-sizing(border-box);

Sass:

@include box-sizing(border-box);

If you need to handle values that cannot be converted separately, you can use this method:

try {
    $valueToUse = trim($stringThatMightBeNumeric) + 0;
} catch (\Throwable $th) {
    // bail here if you need to
}

It's time to be a big boy and install from source. Try this:

1) Download the MySQL-python-1.X.X.tar.gz file(by default will go to your Downloads directory)

2) Open a Terminal window and cd to the Downloads directory.

3) Unzip the file you downloaded:

~/Downloads$ tar xfvz MySQL-python-1.X.X.tar.gz

That will create a directory inside your Downloads directory called MySQL-python

4) cd into the newly created directory.

5) Typically, you just open the file called README or INSTALL and follow the instructions--but generally to install a python module all you do is:

$ sudo python setup.py install

If you care to look, there should be a file called setup.py inside your newly created MySQL-python directory, and you are invoking that program to install the module.

Also note that this:

export PATH=$PATH:/usr/local/mysql/bin

is not permanent if you did that on the command line. You need to put that line in a file called .bashrc in your home directory (~/ or equivalently /Users/YOUR_USER_NAME). To see if .bashrc already exists(it's a hidden file), issue the command:

$ ls -al 

and look for .bashrc. If .bashrc doesn't exist, then create it.

There's no difference, == is a synonym for = (for the C/C++ people, I assume). See here, for example.

You could double-check just to be really sure or just for your interest by looking at the bash source code, should be somewhere in the parsing code there, but I couldn't find it straightaway.

The "d.ts" file is used to provide typescript type information about an API that's written in JavaScript. The idea is that you're using something like jQuery or underscore, an existing javascript library. You want to consume those from your typescript code.

Rather than rewriting jquery or underscore or whatever in typescript, you can instead write the d.ts file, which contains only the type annotations. Then from your typescript code you get the typescript benefits of static type checking while still using a pure JS library.

My take on this, as a good exercise - vparse, which has a tiny source, with a simple function:

function parseVersion(v) {
    var m = v.match(/\d*\.|\d+/g) || [];
    v = {
        major: +m[0] || 0,
        minor: +m[1] || 0,
        patch: +m[2] || 0,
        build: +m[3] || 0
    };
    v.isEmpty = !v.major && !v.minor && !v.patch && !v.build;
    v.parsed = [v.major, v.minor, v.patch, v.build];
    v.text = v.parsed.join('.');
    return v;
}

For clarification, here is a more detailed example demonstrating Form Validation using jQuery Validation Unobtrusive.

Both use the following JavaScript with jQuery:

  $("#commentForm").validate({
    submitHandler: function(form) {
      // some other code
      // maybe disabling submit button
      // then:
      alert("This is a valid form!");
//      form.submit();
    }
  });

The main differences between the two plugins are the attributes used for each approach.

jQuery Validation

Simply use the following attributes:

• Set required if required
• Set type for proper formatting (email, etc.)
• Set other attributes such as size (min length, etc.)

Here's the form...

<form id="commentForm">
  <label for="form-name">Name (required, at least 2 characters)</label>
  <input id="form-name" type="text" name="form-name" class="form-control" minlength="2" required>
  <input type="submit" value="Submit">
</form>

jQuery Validation Unobtrusive

The following data attributes are needed:

• data-msg-required="This is required."
• data-rule-required="true/false"

Here's the form...

<form id="commentForm">
  <label for="form-x-name">Name (required, at least 2 characters)</label>
  <input id="form-x-name" type="text" name="name" minlength="2" class="form-control" data-msg-required="Name is required." data-rule-required="true">
  <input type="submit" value="Submit">
</form>

Based on either of these examples, if the form fields that are required have been filled, and they meet the additional attribute criteria, then a message will pop up notifying that all form fields are validated. Otherwise, there will be text near the offending form fields that indicates the error.

Use phpinfo() and search for Configuration File (php.ini) Path to see which config file path for php is used. PHP can have multiple config files depending on environment it's running. Usually, for console it's:

/etc/php5/cli/php.ini

and for php run by apache it's:

/etc/php5/apache2/php.ini

And then set error_reporting the way you need it:

From an SEO perspective, choosing whether or not to include a trailing slash at the end of a URL is irrelevant. These days, it is common to see examples of both on the web. A site will not be penalized either way, nor will this choice affect your website's search engine ranking or other SEO considerations.

Just choose a URL naming convention you prefer, and include a canonical meta tag in the <head> section of each webpage.

Search engines may consider a single webpage as two separate duplicate URLS when they encounter it with and without the trailing slash, ie example.com/about-us/ and example.com/about-us.

It is best practice to include a canonical meta tag on each page because you cannot control how other sites link to your URLs.

The canonical tag looks like this: <link rel="canonical" href="https://example.com/about-us" />. Using a canonical meta tag ensures that search engines only count each of your URLs once, regardless of whether other websites include a trailing slash when they link to your site.

ViewWillAppear is an override method of UIViewController class so adding a subView will not call viewWillAppear, but when you present, push , pop, show , setFront Or popToRootViewController from a viewController then viewWillAppear for presented viewController will get called.

Try this one, it works fine for me.

In CSS:

::-webkit-scrollbar
{
    width: 0px;
}
::-webkit-scrollbar-track-piece
{
    background-color: transparent;
    -webkit-border-radius: 6px;
}

and here is the working demo: https://jsfiddle.net/qpvnecz5/

The form tag needs some attributes set:

1. action: The URL that the form data is sent to on submit. Generate it with url_for. It can be omitted if the same URL handles showing the form and processing the data.
2. method="post": Submits the data as form data with the POST method. If not given, or explicitly set to get, the data is submitted in the query string (request.args) with the GET method instead.
3. enctype="multipart/form-data": When the form contains file inputs, it must have this encoding set, otherwise the files will not be uploaded and Flask won't see them.

The input tag needs a name parameter.

Add a view to handle the submitted data, which is in request.form under the same key as the input's name. Any file inputs will be in request.files.

@app.route('/handle_data', methods=['POST'])
def handle_data():
    projectpath = request.form['projectFilepath']
    # your code
    # return a response

Set the form's action to that view's URL using url_for:

<form action="{{ url_for('handle_data') }}" method="post">
    <input type="text" name="projectFilepath">
    <input type="submit">
</form>

Have you considered using plain old javascript?

var box = document.getElementById('aioConceptName');

conceptName = box.options[box.selectedIndex].text;

You could use cursor.lastrowid (see "Optional DB API Extensions"):

connection=sqlite3.connect(':memory:')
cursor=connection.cursor()
cursor.execute('''CREATE TABLE foo (id integer primary key autoincrement ,
                                    username varchar(50),
                                    password varchar(50))''')
cursor.execute('INSERT INTO foo (username,password) VALUES (?,?)',
               ('test','test'))
print(cursor.lastrowid)
# 1

If two people are inserting at the same time, as long as they are using different cursors, cursor.lastrowid will return the id for the last row that cursor inserted:

cursor.execute('INSERT INTO foo (username,password) VALUES (?,?)',
               ('blah','blah'))

cursor2=connection.cursor()
cursor2.execute('INSERT INTO foo (username,password) VALUES (?,?)',
               ('blah','blah'))

print(cursor2.lastrowid)        
# 3
print(cursor.lastrowid)
# 2

cursor.execute('INSERT INTO foo (id,username,password) VALUES (?,?,?)',
               (100,'blah','blah'))
print(cursor.lastrowid)
# 100

Note that lastrowid returns None when you insert more than one row at a time with executemany:

cursor.executemany('INSERT INTO foo (username,password) VALUES (?,?)',
               (('baz','bar'),('bing','bop')))
print(cursor.lastrowid)
# None

Opening a file creates it and (unless append ('a') is set) overwrites it with emptyness, such as this:

open(filename, 'w').close()
