I'm assuming you figured this out already but:
Technical Reference for Log Files in Configuration Manager
That's a list of client-side logs and what they do. They are located in Windows\CCM\Logs
AppEnforce.log
will show you the actual command-line executed and the resulting exit code for each Deployment Type (only for the new style ConfigMgr Applications)
This is my go-to for troubleshooting apps. Haven't really found any other logs that are exceedingly useful.
Python lists are heterogeneous that is the elements in the same list can be any type of object. The expression: c.append(c)
appends the object c
what ever it may be to the list. In the case it makes the list itself a member of the list.
The expression c += c
adds two lists together and assigns the result to the variable c
. The overloaded +
operator is defined on lists to create a new list whose contents are the elements in the first list and the elements in the second list.
So these are really just different expressions used to do different things by design.
Assuming employee numbers are in the first column and their names are in the second:
=VLOOKUP(A1, Sheet2!A:B, 2,false)
FLAnimatedImage is a performant open source animated GIF engine for iOS:
It's a well-tested component that I wrote to power all GIFs in Flipboard.
<sj:datepicker id="datepickerid" name="datepickername" displayFormat="%{formatDateJsp}" readonly="true"/>
Works for me.
Here is a practical example (there are several good ones already). I just wanted to add one that is useful to almost any developer.
At some point, developers will need to parse an object as with a response from an API or some type of object or array.
This function is initially called to parse an object which may just contain parameters, but what if the object also contains other objects or arrays? This will need to be addressed, and for the most part the basic function already does this, so the function just calls itself again (after confirming that the key or value is either an object or an array) and parses this new object or array. Ultimately what is returned is a string that creates each parameter on a line by itself for readability, but you could just as easily log the values to a log file or insert into a DB or whatever.
I added the $prefix
parameter to use the parent element to help describe the end variable so that we can see what the value pertains to. It doesn't include things like null values, but this can be amended from this example.
If you have the object:
$apiReturn = new stdClass();
$apiReturn->shippingInfo = new stdClass();
$apiReturn->shippingInfo->fName = "Bill";
$apiReturn->shippingInfo->lName = "Test";
$apiReturn->shippingInfo->address1 = "22 S. Deleware St.";
$apiReturn->shippingInfo->city = "Chandler";
$apiReturn->shippingInfo->state = "AZ";
$apiReturn->shippingInfo->zip = 85225;
$apiReturn->phone = "602-312-4455";
$apiReturn->transactionDetails = array(
"totalAmt" => "100.00",
"currency" => "USD",
"tax" => "5.00",
"shipping" => "5.00"
);
$apiReturn->item = new stdClass();
$apiReturn->item->name = "T-shirt";
$apiReturn->item->color = "blue";
$apiReturn->item->itemQty = 1;
and use:
var_dump($apiReturn);
it will return:
object(stdClass)#1 (4) { ["shippingInfo"]=> object(stdClass)#2 (6) { ["fName"]=> string(4) "Bill" ["lName"]=> string(4) "Test" ["address1"]=> string(18) "22 S. Deleware St." ["city"]=> string(8) "Chandler" ["state"]=> string(2) "AZ" ["zip"]=> int(85225) } ["phone"]=> string(12) "602-312-4455" ["transactionDetails"]=> array(4) { ["totalAmt"]=> string(6) "100.00" ["currency"]=> string(3) "USD" ["tax"]=> string(4) "5.00" ["shipping"]=> string(4) "5.00" } ["item"]=> object(stdClass)#3 (3) { ["name"]=> string(7) "T-shirt" ["color"]=> string(4) "blue" ["itemQty"]=> int(1) } }
and here is the code to parse it into a string with a line break for each parameter:
function parseObj($obj, $prefix = ''){
$stringRtrn = '';
foreach($obj as $key=>$value){
if($prefix){
switch ($key) {
case is_array($key):
foreach($key as $k=>$v){
$stringRtrn .= parseObj($key, $obj);
}
break;
case is_object($key):
$stringRtrn .= parseObj($key, $obj);
break;
default:
switch ($value) {
case is_array($value):
$stringRtrn .= parseObj($value, $key);
break;
case is_object($value):
$stringRtrn .= parseObj($value, $key);
break;
default:
$stringRtrn .= $prefix ."_". $key ." = ". $value ."<br>";
break;
}
break;
}
} else { // end if($prefix)
switch($key){
case is_array($key):
$stringRtrn .= parseObj($key, $obj);
break;
case is_object($key):
$stringRtrn .= parseObj($key, $obj);
break;
default:
switch ($value) {
case is_array($value):
$stringRtrn .= parseObj($value, $key);
break;
case is_object($value):
$stringRtrn .= parseObj($value, $key);
break;
default:
$stringRtrn .= $key ." = ". $value ."<br>";
break;
} // end inner switch
} // end outer switch
} // end else
} // end foreach($obj as $key=>$value)
return $stringRtrn;
} // END parseObj()
This will return the object as follows:
shippingInfo_fName = Bill
shippingInfo_lName = Test
shippingInfo_address1 = 22 S. Deleware St.
shippingInfo_city = Chandler
shippingInfo_state = AZ
shippingInfo_zip = 85225
phone = 602-312-4455
transactionDetails_totalAmt = 100.00
transactionDetails_currency = USD
transactionDetails_tax = 5.00
transactionDetails_shipping = 5.00
item_name = T-shirt
item_color = blue
item_itemQty = 1
I did the nested switch statements to avoid confusion with if . . . ifelse . . . else
, but it was almost as long. If it helps, just ask for the if conditionals and I can paste them for those who need it.
this is a sample of one of my app how i handle
//searching for the Edit Text in the view
final EditText myEditText =(EditText)view.findViewById(R.id.myEditText);
myEditText.setOnKeyListener(new View.OnKeyListener() {
public boolean onKey(View v, int keyCode, KeyEvent event) {
if (event.getAction() == KeyEvent.ACTION_DOWN)
if ((keyCode == KeyEvent.KEYCODE_DPAD_CENTER) ||
(keyCode == KeyEvent.KEYCODE_ENTER)) {
//do something
//true because you handle the event
return true;
}
return false;
}
});
I did it! Using <intent-filter>
. Put the following into your manifest file:
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data android:host="www.youtube.com" android:scheme="http" />
</intent-filter>
This works perfectly!
You absolutely need to know where the files to be read can be located. However, this information can be relative of course so it may be well adapted to other systems.
So it could relate to the current directory (get it from Directory.GetCurrentDirectory()
) or to the application executable path (eg. Application.ExecutablePath
comes to mind if using Windows Forms or via Assembly.GetEntryAssembly().Location
) or to some special Windows directory like "Documents and Settings" (you should use Environment.GetFolderPath()
with one element of the Environment.SpecialFolder
enumeration).
Note that the "current directory" and the path of the executable are not necessarily identical. You need to know where to look!
In either case, if you need to manipulate a path use the Path class to split or combine parts of the path.
You cannot calculate the differences separately ... what difference would that yield for 7:59 and 8:00 o'clock? Try
import time
time.time()
which gives you the seconds since the start of the epoch.
You can then get the intermediate time with something like
timestamp1 = time.time()
# Your code here
timestamp2 = time.time()
print "This took %.2f seconds" % (timestamp2 - timestamp1)
How about using unique()
itself?
df <- data.frame(yad = c("BARBIE", "BARBIE", "BAKUGAN", "BAKUGAN"),
per = c("AYLIK", "AYLIK", "2 AYLIK", "2 AYLIK"),
hmm = 1:4)
df
# yad per hmm
# 1 BARBIE AYLIK 1
# 2 BARBIE AYLIK 2
# 3 BAKUGAN 2 AYLIK 3
# 4 BAKUGAN 2 AYLIK 4
unique(df[c("yad", "per")])
# yad per
# 1 BARBIE AYLIK
# 3 BAKUGAN 2 AYLIK
from cmd run: SVN List URL you will be provided with 3 options (r)eject, (a)ccept, (p)ermanently. enter p. This resolved issue for me
if you want to populate a table in SQL SERVER you can use while statement as follows:
declare @llenandoTabla INT = 0;
while @llenandoTabla < 10000
begin
insert into employeestable // Name of my table
(ID, FIRSTNAME, LASTNAME, GENDER, SALARY) // Parameters of my table
VALUES
(555, 'isaias', 'perez', 'male', '12220') //values
set @llenandoTabla = @llenandoTabla + 1;
end
Hope it helps.
Here's an option if you need to escape multiple %'s in a string with some already escaped.
(?:[^%]|^)(?:(%%)+|)(%)(?:[^%])
To sanitise the message before passing it to String.format, you can use the following
Pattern p = Pattern.compile("(?:[^%]|^)(?:(%%)+|)(%)(?:[^%])");
Matcher m1 = p.matcher(log);
StringBuffer buf = new StringBuffer();
while (m1.find())
m1.appendReplacement(buf, log.substring(m1.start(), m1.start(2)) + "%%" + log.substring(m1.end(2), m1.end()));
// Return the sanitised message
String escapedString = m1.appendTail(buf).toString();
This works with any number of formatting characters, so it will replace % with %%, %%% with %%%%, %%%%% with %%%%%% etc.
It will leave any already escaped characters alone (e.g. %%, %%%% etc.)

In addition to the above answers to exemplify invocation order, a simple run example
class myclass:
def __init__(self):
print("__init__")
def __enter__(self):
print("__enter__")
def __exit__(self, type, value, traceback):
print("__exit__")
def __del__(self):
print("__del__")
with myclass():
print("body")
Produces the output:
__init__
__enter__
body
__exit__
__del__
A reminder: when using the syntax with myclass() as mc
, variable mc gets the value returned by __enter__()
, in the above case None
! For such use, need to define return value, such as:
def __enter__(self):
print('__enter__')
return self
Here is simple solution for PHP 5.4+
namespace {
trait Names {
public static function getNamespace() {
return implode('\\', array_slice(explode('\\', get_called_class()), 0, -1));
}
public static function getBaseClassName() {
return basename(str_replace('\\', '/', get_called_class()));
}
}
}
What will be return?
namespace x\y\z {
class SomeClass {
use \Names;
}
echo \x\y\z\SomeClass::getNamespace() . PHP_EOL; // x\y\z
echo \x\y\z\SomeClass::getBaseClassName() . PHP_EOL; // SomeClass
}
Extended class name and namespace works well to:
namespace d\e\f {
class DifferentClass extends \x\y\z\SomeClass {
}
echo \d\e\f\DifferentClass::getNamespace() . PHP_EOL; // d\e\f
echo \d\e\f\DifferentClass::getBaseClassName() . PHP_EOL; // DifferentClass
}
What about class in global namespace?
namespace {
class ClassWithoutNamespace {
use \Names;
}
echo ClassWithoutNamespace::getNamespace() . PHP_EOL; // empty string
echo ClassWithoutNamespace::getBaseClassName() . PHP_EOL; // ClassWithoutNamespace
}
After following Tim Davis' guide and Steve's follow-up, here is what I did:
Server PC
Add the following to the user's CopSSH/home/user/.bashrc file:
GITPATH='/cygdrive/c/Program Files (x86)/Git/bin'
GITCOREPATH='/cygdrive/c/Program Files (x86)/Git/libexec/git-core'
PATH=${GITPATH}:${GITCOREPATH}:${PATH}
Open Git Bash and create a repository anywhere on your PC:
$ git --bare init repo.git
Initialized empty Git repository in C:/repopath/repo.git/
Client PC
This allowed me to successfully clone and commit, but I could not push to the bare repo on the server. I kept getting:
git: '/repopath/repo.git' is not a git command. See 'git --help'.
fatal: The remote end hung up unexpectedly
This led me to Rui's trace and solution which was to create or add the following lines to .gitconfig in your Client PC's %USERPROFILE% path (C:\Users\UserName).
[remote "origin"]
receivepack = git receive-pack
I am not sure why this is needed...if anybody could provide insight, this would be helpful.
my git version is 1.7.3.1.msysgit.0
If you want an index, you can use std::find
in combination with std::distance
.
auto it = std::find(Names.begin(), Names.end(), old_name_);
if (it == Names.end())
{
// name not in vector
} else
{
auto index = std::distance(Names.begin(), it);
}
The following code works fine:
@using (Html.BeginForm("Upload", "Upload", FormMethod.Post,
new { enctype = "multipart/form-data" }))
{
@Html.ValidationSummary(true)
<fieldset>
Select a file <input type="file" name="file" />
<input type="submit" value="Upload" />
</fieldset>
}
and generates as expected:
<form action="/Upload/Upload" enctype="multipart/form-data" method="post">
<fieldset>
Select a file <input type="file" name="file" />
<input type="submit" value="Upload" />
</fieldset>
</form>
On the other hand if you are writing this code inside the context of other server side construct such as an if
or foreach
you should remove the @
before the using
. For example:
@if (SomeCondition)
{
using (Html.BeginForm("Upload", "Upload", FormMethod.Post,
new { enctype = "multipart/form-data" }))
{
@Html.ValidationSummary(true)
<fieldset>
Select a file <input type="file" name="file" />
<input type="submit" value="Upload" />
</fieldset>
}
}
As far as your server side code is concerned, here's how to proceed:
[HttpPost]
public ActionResult Upload(HttpPostedFileBase file)
{
if (file != null && file.ContentLength > 0)
{
var fileName = Path.GetFileName(file.FileName);
var path = Path.Combine(Server.MapPath("~/content/pics"), fileName);
file.SaveAs(path);
}
return RedirectToAction("Upload");
}
I'm not sure if this is quite what you're looking for but I've had a lot of success using an HTML to Postscript converter html2ps to create postscript copies of web pages, which I then convert to .gif or .pngs
This doesn't produce exact screenshot quality that you'd get from a web browser and doesn't handle complicated things like flash or css all that well, but the advantage is that you can run it on the web server.
(I use it to create thumbnails of user created content, for navigation)
There is a simple way of passing parameters into runnables. Code:
public void Function(final type variable) {
Runnable runnable = new Runnable() {
public void run() {
//Code adding here...
}
};
new Thread(runnable).start();
}
For Basic Authentication of WSDL the accepted answers code raises an error. Try the following instead
Authenticator.setDefault(new Authenticator() {
@Override
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication("username","password".toCharArray());
}
});
This will list Everything (including sub directories) from the directory you specify, in order, and with the attributes. I have spent days looking for something to do this, and I took parts from this entire discussion, and a little of my own, and put it together. ENJOY!!
#!/usr/bin/perl --
print qq~Content-type: text/html\n\n~;
print qq~<font face="arial" size="2">~;
use File::Find;
# find( \&wanted_tom, '/home/thomas/public_html'); # if you want just one website, uncomment this, and comment out the next line
find( \&wanted_tom, '/home');
exit;
sub wanted_tom {
($dev,$ino,$mode,$nlink,$uid,$gid,$rdev,$size,$atime,$mtime,$ctime,$blksize,$blocks) = stat ($_);
$mode = (stat($_))[2];
$mode = substr(sprintf("%03lo", $mode), -3);
if (-d $File::Find::name) {
print "<br><b>--DIR $File::Find::name --ATTR:$mode</b><br>";
} else {
print "$File::Find::name --ATTR:$mode<br>";
}
return;
}
You can try to use as well this functions to capture StdErr StdOut and return code.
def runShell(String command){
def responseCode = sh returnStatus: true, script: "${command} &> tmp.txt"
def output = readFile(file: "tmp.txt")
if (responseCode != 0){
println "[ERROR] ${output}"
throw new Exception("${output}")
}else{
return "${output}"
}
}
Notice:
&>name means 1>name 2>name -- redirect stdout and stderr to the file name
Creating the template page is the correct answer. For this, just add this into the page you created inside the theme folder:
<?php
/*
Template Name: mytemplate
*/
?>
For running this code, you need to select "mytemplate" as the template of the page from the back end.
Please see this link for getting the correct details https://developer.wordpress.org/themes/template-files-section/page-template-files/.
Starting Python 3.8
, the standard library provides the NormalDist
object as part of the statistics
module:
from statistics import NormalDist
def confidence_interval(data, confidence=0.95):
dist = NormalDist.from_samples(data)
z = NormalDist().inv_cdf((1 + confidence) / 2.)
h = dist.stdev * z / ((len(data) - 1) ** .5)
return dist.mean - h, dist.mean + h
This:
Creates a NormalDist
object from the data sample (NormalDist.from_samples(data)
, which gives us access to the sample's mean and standard deviation via NormalDist.mean
and NormalDist.stdev
.
Compute the Z-score
based on the standard normal distribution (represented by NormalDist()
) for the given confidence using the inverse of the cumulative distribution function (inv_cdf
).
Produces the confidence interval based on the sample's standard deviation and mean.
This assumes the sample size is big enough (let's say more than ~100 points) in order to use the standard normal distribution rather than the student's t distribution to compute the z
value.
in my case, I try tried File
>Invalidate Cache/Restart
and that works for me.
I've been using this line to launch the default browser:
System.Diagnostics.Process.Start("http://www.google.com");
You need the Microsoft.AspNet.WebApi.Core package.
You can see it in the .csproj file:
<Reference Include="System.Web.Http, Version=5.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35, processorArchitecture=MSIL">
<SpecificVersion>False</SpecificVersion>

In my case it was because it was being backed up my a background process which started before I opened Access. It isn't normally a problem if it have the database open when the backup starts.
You are consuming a line at, which is discarded
while((str=input.readLine())!=null && str.length()!=0)
and reading a bigint at
BigInteger n = new BigInteger(input.readLine());
so try getting the bigint from string which is read as
BigInteger n = new BigInteger(str);
Constructor used: BigInteger(String val)
Aslo change while((str=input.readLine())!=null && str.length()!=0)
to
while((str=input.readLine())!=null)
see related post string to bigint
readLine()
Returns:
A String containing the contents of the line, not including any line-termination characters, or null if the end of the stream has been reached
see javadocs
The alternative way to check if an array is empty could be:
count($array)>0
It works for me without that error
Even if this thread is old is the first on Google, so I'll post an Oracle equivalent to the function implemented here, using regular expressions.
Is fairly faster than nested replace(), and much cleaner.
To replace strings 'a','b','c' with 'd' in a string column from a given table
select regexp_replace(string_col,'a|b|c','d') from given_table
It is nothing else than a regular expression for several static patterns with 'or' operator.
Beware of regexp special characters!
As you are already using jQuery, you can use the grep function which is intended for searching an array:
var result = $.grep(myArray, function(e){ return e.id == id; });
The result is an array with the items found. If you know that the object is always there and that it only occurs once, you can just use result[0].foo
to get the value. Otherwise you should check the length of the resulting array. Example:
if (result.length === 0) {
// no result found
} else if (result.length === 1) {
// property found, access the foo property using result[0].foo
} else {
// multiple items found
}

schema definition as simple string
Just in case if some one is interested in schema definition as simple string with date and time stamp
data file creation from Terminal or shell
echo "
2019-07-02 22:11:11.000999, 01/01/2019, Suresh, abc
2019-01-02 22:11:11.000001, 01/01/2020, Aadi, xyz
" > data.csv
Defining the schema as String
user_schema = 'timesta TIMESTAMP,date DATE,first_name STRING , last_name STRING'
reading the data
df = spark.read.csv(path='data.csv', schema = user_schema, sep=',', dateFormat='MM/dd/yyyy',timestampFormat='yyyy-MM-dd HH:mm:ss.SSSSSS')
df.show(10, False)
+-----------------------+----------+----------+---------+
|timesta |date |first_name|last_name|
+-----------------------+----------+----------+---------+
|2019-07-02 22:11:11.999|2019-01-01| Suresh | abc |
|2019-01-02 22:11:11.001|2020-01-01| Aadi | xyz |
+-----------------------+----------+----------+---------+
Please note defining the schema explicitly instead of letting spark infer the schema also improves the spark read performance.
For v4 this is a known issue that won't be addressed in 4.0 but there is a workaround. Check https://github.com/select2/select2/issues/2830
Aergistal's answer works, but I found that converting to mp4 can make some m3u8 videos broken. If you are stuck with this problem, try to convert them to mkv, and convert them to mp4 later.
I dont want to use like this
That is the syntax for Update
statement in SQL, you have to use that syntax otherwise you will get the exception.
command.Text = "UPDATE Student SET Address = @add, City = @cit Where FirstName = @fn AND LastName = @ln";
and then add your parameters accordingly.
command.Parameters.AddWithValue("@ln", lastName);
command.Parameters.AddWithValue("@fn", firstName);
command.Parameters.AddWithValue("@add", address);
command.Parameters.AddWithValue("@cit", city);
Very nice pdf about many GIT secrets.
Add is same as svn's add (how ever sometimes it is used to mark file resolved).
Commit also is same as svn's , but it commit change into your local repository.
In my case i just needed to pass the whole url and encode only the value of each parameters. I didn't find a common code to do that so (!!) so i created this small method to do the job :
public static String encodeUrl(String url) throws Exception {
if (url == null || !url.contains("?")) {
return url;
}
List<String> list = new ArrayList<>();
String rootUrl = url.split("\\?")[0] + "?";
String paramsUrl = url.replace(rootUrl, "");
List<String> paramsUrlList = Arrays.asList(paramsUrl.split("&"));
for (String param : paramsUrlList) {
if (param.contains("=")) {
String key = param.split("=")[0];
String value = param.replace(key + "=", "");
list.add(key + "=" + URLEncoder.encode(value, "UTF-8"));
}
else {
list.add(param);
}
}
return rootUrl + StringUtils.join(list, "&");
}
public static String decodeUrl(String url) throws Exception {
return URLDecoder.decode(url, "UTF-8");
}
It uses org.apache.commons.lang3.StringUtils
You can pass via GET. So if you want to pass the value foobar
from PageA.php
to PageB.php
, call it as PageB.php?value=foobar
.
In PageB.php, you can access it this way:
$value = $_GET['value'];
If you're using Python < 3, you'll need to tell the interpreter that your string literal is Unicode by prefixing it with a u

.selector { scale(1400px, 16px, 5px, 20px, $property: padding-right); scale(1400px, 16px, 5px, 20px, $property: padding-left); }
This would scale down to 5px and up to 20px, between 5-20 it is dynamic based of vw
In your first example, you are correct. The batch will hit the commit transaction, regardless of whether the try block fires.
In your second example, I agree with other commenters. Using the success flag is unnecessary.
I consider the following approach to be, essentially, a light weight best practice approach.
If you want to see how it handles an exception, change the value on the second insert from 255 to 256.
CREATE TABLE #TEMP ( ID TINYINT NOT NULL );
INSERT INTO #TEMP( ID ) VALUES ( 1 )
BEGIN TRY
BEGIN TRANSACTION
INSERT INTO #TEMP( ID ) VALUES ( 2 )
INSERT INTO #TEMP( ID ) VALUES ( 255 )
COMMIT TRANSACTION
END TRY
BEGIN CATCH
DECLARE
@ErrorMessage NVARCHAR(4000),
@ErrorSeverity INT,
@ErrorState INT;
SELECT
@ErrorMessage = ERROR_MESSAGE(),
@ErrorSeverity = ERROR_SEVERITY(),
@ErrorState = ERROR_STATE();
RAISERROR (
@ErrorMessage,
@ErrorSeverity,
@ErrorState
);
ROLLBACK TRANSACTION
END CATCH
SET NOCOUNT ON
SELECT ID
FROM #TEMP
DROP TABLE #TEMP
I had the same issue. Fixed it by adding a static route on my host to my VM via the VMnet8 adapter:
route ADD VM_addr MASK 255.255.255.255 VMnet8_addr
As previously mentioned, you need a bridged connection.
SELECT chargeId, chargeType, MAX(serviceMonth) AS serviceMonth
FROM invoice
GROUP BY chargeId, chargeType
Check out what's in your database.yml
file. If you already have your plain Rails app and simply wrapping it with Docker, you should change (inside database.yml
):
socket: /var/run/mysqld/mysqld.sock #just comment it out
to
host: db
where db
is the name of my db-service from docker-compose.yml
. And here's my docker-compose.yml
:
version: '3'
services:
web:
build: .
command: bundle exec rails s -p 3000 -b '0.0.0.0'
volumes:
- .:/myapp
ports:
- "3000:3000"
links:
- db
db:
image: mysql:5.7
environment:
MYSQL_ROOT_PASSWORD: root
You start your app in console (in app folder) as docker-compose up
. Then WAIT 1 MINUTE (let your mysql service to completely load) until some new logs stop appearing in console. Usually the last line should be like
db_1 | 2017-12-24T12:25:20.397174Z 0 [Note] End of list of non-natively partitioned tables
Then (in a new terminal window) apply:
docker-compose run web rake db:create
and then
docker-compose run web rake db:migrate
After you finish your work stop the loaded images with
docker-compose stop
Don't use docker-compose down
here instead because if you do, you will erase your database content.
Next time when you want to resume your work apply:
docker-compose start
The rest of the things do exactly as explained here: https://docs.docker.com/compose/rails/
Sorry, my english is not that good. But i like to improve the upvoted answers. I think that using Dictionary is more simple and clean.
class Program
{
static void Main(string[] args)
{
agencia ag1 = new agencia()
{
name = "Iquique",
data = new object[] { new object[] {"Lucas", 20 }, new object[] {"Fernando", 15 } }
};
agencia ag2 = new agencia()
{
name = "Valparaiso",
data = new object[] { new object[] { "Rems", 20 }, new object[] { "Perex", 15 } }
};
agencia agn = new agencia()
{

Console.WriteLine(da);
Console.ReadLine();
}
}
public class agencia

From Terminal just run this command:
ios-sim start
Or,add this to your ~/.profile
to save yourself a few keystrokes:
alias ios="ios-sim start"
Not sure which version of Max OS X and Xcode this command became available. I'm running 10.10.3 and 6.3 respectively.
Since you already have <Tags>
component calling a function on its parent, you do not need additional state: simply pass the filter to the <Tags>
component as a prop, and use this in rendering your buttons. Like so:
Change your render function inside your <Tags>
component to:
render: function() {
return <div className = "tags">
<button className = {this._checkActiveBtn('')} onClick = {this.setFilter.bind(this, '')}>All</button>
<button className = {this._checkActiveBtn('male')} onClick = {this.setFilter.bind(this, 'male')}>male</button>
<button className = {this._checkActiveBtn('female')} onClick = {this.setFilter.bind(this, 'female')}>female</button>
<button className = {this._checkActiveBtn('blonde')} onClick = {this.setFilter.bind(this, 'blonde')}>blonde</button>
</div>
},
And add a function inside <Tags>
:
_checkActiveBtn: function(filterName) {
return (filterName == this.props.activeFilter) ? "btn active" : "btn";
}
And inside your <List>
component, pass the filter state to the <tags>
component as a prop:
return <div>
<h2>Kids Finder</h2>
<Tags filter = {this.state.filter} onChangeFilter = {this.changeFilter} />
{list}
</div>
Then it should work as intended. Codepen here (hope the link works)

This is the code required if you're using only JavaScript and not jQuery
var el = document.getElementById("id");
el.addEventListener("click", function(){alert("click1 triggered")}, false);
el.addEventListener("click", function(){alert("click2 triggered")}, false);

be careful it's root of the domain.
P.S. and please use lowercase for attribute names.
std::vector
has a constructor that takes two iterators. You can use that:
std::string str = "hello";
std::vector<char> data(str.begin(), str.end());
If you already have a vector and want to add the characters at the end, you need a back inserter:
std::string str = "hello";
std::vector<char> data = /* ... */;
std::copy(str.begin(), str.end(), std::back_inserter(data));
You have to use the isomorphic-fetch
module to your Node
project because of Node
does not contain Fetch API
yet. for fixing this problem run below command:
npm install --save isomorphic-fetch es6-promise
After installation use below code in your project:
import "isomorphic-fetch"
Hope this answer helps you.
There are a couple of answers posted here that will give you the text effects you want, but...
The thing about tables is that they are organized collections of labels and data. Having both a label ("Datum") and the value that it labels in the same cell is oh so very wrong. The label should be in a <th>
element, with the value in a <td>
either in the same row or the same column (depending on the data arrangement you are trying to achieve). You can have <th>
elements running either vertically or horizontally or both, but if you don't have heading cells (which is what <th>
means), you don't have a table, you just have a meaningless grid of text. It would be preferable, too, to have a <caption>
element to label the table as a whole (you don't have to display the caption, but it should be there for accessibility) and have a summary="blah blah blah"
attribute in the table tag, again for accessibility. So your HTML should probably look a lot more like this:
<html>
<head>
<title>Test page with Table<title>
<style type="text/css">
th {
font-size: 35px;
font-weight: bold;
padding-left: 5px;
padding-bottom: 3px;
}
</style>
</head>
<body>
<table id="table_1" summary="This table has both labels and values">
<caption>Table of Stuff</caption>
<tr>
<th>Datum</th>
<td>November 2010</td>
</tr>
</table>
</body>
</html>
That may not be exactly what you want -- it's hard to tell whether November 2010 is a data point or a label from what you've posted, and "Datum" isn't a helpful label in any case. Play with it a bit, but make sure that when your table is finished it actually has some kind of semantic meaning. If it's not a real table of data, then don't use a <table>
to lay it out.
The STAThreadAttribute
is essentially a requirement for the Windows message pump to communicate with COM components. Although core Windows Forms does not use COM, many components of the OS such as system dialogs do use this technology.
MSDN explains the reason in slightly more detail:
STAThreadAttribute indicates that the COM threading model for the application is single-threaded apartment. This attribute must be present on the entry point of any application that uses Windows Forms; if it is omitted, the Windows components might not work correctly. If the attribute is not present, the application uses the multithreaded apartment model, which is not supported for Windows Forms.
This blog post (Why is STAThread required?) also explains the requirement quite well. If you want a more in-depth view as to how the threading model works at the CLR level, see this MSDN Magazine article from June 2004 (Archived, Apr. 2009).
The best way to do this is to use response interceptors along with custom directive. And the process can further be improved using pub/sub mechanism using $rootScope.$broadcast & $rootScope.$on methods.
As the whole process is documented in a well written blog article, I'm not going to repeat that here again. Please refer to that article to come up with your needed implementation.
Off the top of my head, no.
I think the best you could do is something like this:
def loop(f,n):
for i in xrange(n): f()
loop(lambda: <insert expression here>, 5)
But I think you can just live with the extra i
variable.
Here is the option to use the _
variable, which in reality, is just another variable.
for _ in range(n):
do_something()
Note that _
is assigned the last result that returned in an interactive python session:
>>> 1+2
3
>>> _
3
For this reason, I would not use it in this manner. I am unaware of any idiom as mentioned by Ryan. It can mess up your interpreter.
>>> for _ in xrange(10): pass
...
>>> _
9
>>> 1+2
3
>>> _
9
And according to Python grammar, it is an acceptable variable name:
identifier ::= (letter|"_") (letter | digit | "_")*
This Function takes the URL then returns the image BASE64
function getBase64FromImageUrl(url) {
var img = new Image();
img.setAttribute('crossOrigin', 'anonymous');
img.onload = function () {
var canvas = document.createElement("canvas");
canvas.width =this.width;
canvas.height =this.height;
var ctx = canvas.getContext("2d");
ctx.drawImage(this, 0, 0);
var dataURL = canvas.toDataURL("image/png");
alert(dataURL.replace(/^data:image\/(png|jpg);base64,/, ""));
};
img.src = url;
}
Call it like this :
getBase64FromImageUrl("images/slbltxt.png")
I found that these instructions were not enough. I also had to search through the code files for models, controllers, and views as well as the AppStart files to change the namespace.
Since I was copying my project not just renaming it, I also had to go into the applicationhost.config for IIS express and recreate the bindings using different port numbers and change the physical directory as well.
Yes, fill in a Rectangle with a solid color across the canvas, use the height
and width
of the canvas itself:
var canvas = document.getElementById("canvas");
var ctx = canvas.getContext("2d");
ctx.fillStyle = "blue";
ctx.fillRect(0, 0, canvas.width, canvas.height);
_x000D_
canvas{ border: 1px solid black; }
_x000D_
<canvas width=300 height=150 id="canvas">
_x000D_
I had the same problem here, solved like this:
Just add another application-{yourprofile}.yml
where "yourprofile" could be "client".
In my case I just wanted to remove Redis in a Dev profile, so I added a application-dev.yml
next to the main application.yml
and it did the job.
In this file I put:
spring.autoconfigure.exclude: org.springframework.boot.autoconfigure.data.redis.RedisAutoConfiguration,org.springframework.boot.autoconfigure.data.redis.RedisRepositoriesAutoConfiguration
this should work with properties files as well.
I like the fact that there is no need to change the application code to do that.
Have a look at using something like
Converts the string representation of the name or numeric value of one or more enumerated constants to an equivalent enumerated object. A parameter specifies whether the operation is case-sensitive. The return value indicates whether the conversion succeeded.
or
Converts the string representation of the name or numeric value of one or more enumerated constants to an equivalent enumerated object.
.set_title('') can be used to add title to Seaborn Plot

.then(function (response) {
if (response.HasError) {
$scope.HasError = response.HasError;

}]
var EmployeeService = ["$http", "$q",
function ($http, $q) {

.post("/api/EmployeeApi/Create", angular.toJson(employee))
.success(function (response, status, headers, config) {
deferred.resolve(response, status, headers, config);
})
.error(function (response, status, headers, config) {
deferred.reject(response, status, headers, config);
});
return deferred.promise;
};
You can make it even simplier, if you want to avoid extra structures.
service:
mappings:
key1: value1
key2: value2
@Configuration
@EnableConfigurationProperties
public class ServiceConfigurationProperties {
@Bean
@ConfigurationProperties(prefix = "service.mappings")
public Map<String, String> serviceMappings() {
return new HashMap<>();
}
}
And then use it as usual, for example with a constructor:
public class Foo {
private final Map<String, String> serviceMappings;
public Foo(Map<String, String> serviceMappings) {
this.serviceMappings = serviceMappings;
}
}
Check it out in this demo fiddle, go ahead and change the dropdown or default values in the code.
Setting the passenger.Title
with a value that equals to a title.Value
should work.
View:
<select [(ngModel)]="passenger.Title">
<option *ngFor="let title of titleArray" [value]="title.Value">
{{title.Text}}
</option>
</select>
TypeScript used:
class Passenger {
constructor(public Title: string) { };
}
class ValueAndText {
constructor(public Value: string, public Text: string) { }
}
...
export class AppComponent {
passenger: Passenger = new Passenger("Lord");
titleArray: ValueAndText[] = [new ValueAndText("Mister", "Mister-Text"),
new ValueAndText("Lord", "Lord-Text")];
}
there are many options that would change the height of an input box. padding, font-size, height would all do this. different combinations of these produce taller input boxes with different styles. I suggest just changing the font-size (and font-family for looks) and add some padding to make it even taller and also more appealing. I will give you an example of all three style though:
#signin input {
font-size:20px;
}
OR
#signin input {
padding:10px;
}
OR
#signin input {
height:24px;
}
This is the combination of the three that I recommend:
#signin input {
font-size:20px;font-family: "HelveticaNeue-Light", "Helvetica Neue Light", "Helvetica Neue", Helvetica, Arial, "Lucida Grande", sans-serif; font-weight: 300;
padding:10px;
}
Just another way to use Git's awesomeness...
git difftool HEAD HEAD@{N} /PATH/FILE.ext
Use the 64 bit version only if you have to work with heavy amounts of data, in that scenario, the 64 bits performs better with the inconvenient that John La Rooy said; if not, stick with the 32 bits.
I'll have to add an answer here, because the other answers are either not covering my case or are needlessly complicated.
I use github with other developers and I just want all the local branches whose remotes were (possibly merged and) deleted from a github PR to be deleted in one go from my machine. No, things like git branch -r --merged
don't cover the branches that were not merged locally, or the ones that were not merged at all (abandoned) etc, so a different solution is needed.
Anyway, the first step I got it from other answers:
git fetch --prune
A dry run of git remote prune origin
seemed like it would do the same thing in my case, so I went with the shortest version to keep it simple.
Now, a git branch -v
should mark the branches whose remotes are deleted as [gone]
.
Therefore, all I need to do is:
git branch -v|grep \\[gone\\]|awk '{print $1}'|xargs -I{} git branch -D {}
As simple as that, it deletes everything I want for the above scenario.
The less common xargs
syntax is so that it also works on Mac & BSD in addition to Linux.
Careful, this command is not a dry run so it will force-delete all the branches marked as [gone]
. Obviously, this being git nothing is gone forever, if you see branches deleted that you remember you wanted kept you can always undelete them (the above command will have listed their hash on deletion, so a simple git checkout -b <branch> <hash>
.
Edit: Just add this alias to your .bashrc/.bash_profile, the two commands made into one and I updated the second to work on all shells:
alias old_branch_delete='git fetch -p && git branch -vv | awk "/: gone]/{print \$1}" | xargs git branch -D'
Or, you could do it the really simple way.

The problem is with line
imageWidth = 1 * Convert.ToInt32(Label1.Text);
Label1.Text
may or may not be int. Check.
Use Int32.TryParse(value, out number)
instead. That will solve your problem.
int imageWidth;
if(Int32.TryParse(Label1.Text, out imageWidth))
{
Image1.Width= imageWidth;
}
The for-each loop should generally be preferred. The "get" approach may be slower if the List implementation you are using does not support random access. For example, if a LinkedList is used, you would incur a traversal cost, whereas the for-each approach uses an iterator that keeps track of its position in the list. More information on the nuances of the for-each loop.

Use std::stringstream
. Its operator <<
is overloaded for all built-in types.
#include <sstream>
std::stringstream s;
s << "(" << c1 << "," << c2 << ")";
storedCorrect[count] = s.str();
This works like you'd expect - the same way you print to the screen with std::cout
. You're simply "printing" to a string instead. The internals of operator <<
take care of making sure there's enough space and doing any necessary conversions (e.g., double
to string
).
Also, if you have the Boost library available, you might consider looking into lexical_cast
. The syntax looks much like the normal C++-style casts:
#include <string>
#include <boost/lexical_cast.hpp>
using namespace boost;
storedCorrect[count] = "(" + lexical_cast<std::string>(c1) +
"," + lexical_cast<std::string>(c2) + ")";
Under the hood, boost::lexical_cast
is basically doing the same thing we did with std::stringstream
. A key advantage to using the Boost library is you can go the other way (e.g., string
to double
) just as easily. No more messing with atof()
or strtod()
and raw C-style strings.
Your getting the error because you're probably doing it on your Local server environment. You need to skip the certificates check when the cURL call is made. For that just add the following options
curl_setopt($c, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($c, CURLOPT_SSL_VERIFYHOST, 0);
Try this code it is already built in c#
int lastDay = DateTime.DaysInMonth (2014, 2);
and the first day is always 1.
Good Luck!
For me the problem was that I was using obsolete versions of the cordova android and ios platforms. So upgrading to [email protected] and [email protected] solved it.
You can upgrade to these specific versions:
cordova platforms rm android
cordova platforms add [email protected]
cordova platforms rm ios
cordova platforms add [email protected]
I use the jQuery clueTip plugin for this.
Break your path into bucket and object.
Testing the bucket using the method doesBucketExist
,
Testing the object using the size of the listing (0 in case not exist).
So this code will do:
String bucket = ...;
String objectInBucket = ...;
AmazonS3 s3 = new AmazonS3Client(...);
return s3.doesBucketExist(bucket)
&& !s3.listObjects(bucket, objectInBucket).getObjectSummaries().isEmpty();
var date = new Date().toLocaleDateString("en-US");
Also, you can call method toLocaleDateString
with two parameters:
var date = new Date().toLocaleDateString("en-US", {
"year": "numeric",
"month": "numeric"
});
Your PHP array is defined as:
$arr = array ('resonse'=>'error','comment'=>'test comment here');
Notice the mispelling "resonse
". Also, as RaYell has mentioned, you have to use data
instead of json
in your success
function because its parameter is currently data
.
Try editing your PHP file to change the spelling form resonse
to response
. It should work then.
if ( $("#your_select_id option[value=<enter_value_here>]").length == 0 ){
alert("option doesn't exist!");
}
%>%
has no builtin meaning but the user (or a package) is free to define operators of the form %whatever%
in any way they like. For example, this function will return a string consisting of its left argument followed by a comma and space and then it's right argument.
"%,%" <- function(x, y) paste0(x, ", ", y)
# test run
"Hello" %,% "World"
## [1] "Hello, World"
The base of R provides %*%
(matrix mulitiplication), %/%
(integer division), %in%
(is lhs a component of the rhs?), %o%
(outer product) and %x%
(kronecker product). It is not clear whether %%
falls in this category or not but it represents modulo.
expm The R package, expm, defines a matrix power operator %^%
. For an example see Matrix power in R .
operators The operators R package has defined a large number of such operators such as %!in%
(for not %in%
). See http://cran.r-project.org/web/packages/operators/operators.pdf
igraph This package defines %--% , %->% and %<-% to select edges.
lubridate This package defines %m+% and %m-% to add and subtract months and %--% to define an interval. igraph also defines %--% .
magrittr In the case of %>%
the magrittr R package has defined it as discussed in the magrittr vignette. See http://cran.r-project.org/web/packages/magrittr/vignettes/magrittr.html
magittr has also defined a number of other such operators too. See the Additional Pipe Operators section of the prior link which discusses %T>%
, %<>%
and %$%
and http://cran.r-project.org/web/packages/magrittr/magrittr.pdf for even more details.
dplyr The dplyr R package used to define a %.%
operator which is similar; however, it has been deprecated and dplyr now recommends that users use %>%
which dplyr imports from magrittr and makes available to the dplyr user. As David Arenburg has mentioned in the comments this SO question discusses the differences between it and magrittr's %>%
: Differences between %.% (dplyr) and %>% (magrittr)
pipeR The R package, pipeR, defines a %>>%
operator that is similar to magrittr's %>% and can be used as an alternative to it. See http://renkun.me/pipeR-tutorial/
The pipeR package also has defined a number of other such operators too. See: http://cran.r-project.org/web/packages/pipeR/pipeR.pdf
postlogic The postlogic package defined %if%
and %unless%
operators.
wrapr The R package, wrapr, defines a dot pipe %.>%
that is an explicit version of %>%
in that it does not do implicit insertion of arguments but only substitutes explicit uses of dot on the right hand side. This can be considered as another alternative to %>%
. See https://winvector.github.io/wrapr/articles/dot_pipe.html
Bizarro pipe. This is not really a pipe but rather some clever base syntax to work in a way similar to pipes without actually using pipes. It is discussed in http://www.win-vector.com/blog/2017/01/using-the-bizarro-pipe-to-debug-magrittr-pipelines-in-r/ The idea is that instead of writing:
1:8 %>% sum %>% sqrt
## [1] 6
one writes the following. In this case we explicitly use dot rather than eliding the dot argument and end each component of the pipeline with an assignment to the variable whose name is dot (.
) . We follow that with a semicolon.
1:8 ->.; sum(.) ->.; sqrt(.)
## [1] 6
Update Added info on expm package and simplified example at top. Added postlogic package.
Here is a simple directive that will scroll to an element on click:
myApp.directive('scrollOnClick', function() {
return {
restrict: 'A',
link: function(scope, $elm) {
$elm.on('click', function() {
$("body").animate({scrollTop: $elm.offset().top}, "slow");
});
}
}
});
Demo: http://plnkr.co/edit/yz1EHB8ad3C59N6PzdCD?p=preview
For help creating directives, check out the videos at http://egghead.io, starting at #10 "first directive".
edit: To make it scroll to a specific element specified by a href, just check attrs.href
.
myApp.directive('scrollOnClick', function() {
return {
restrict: 'A',
link: function(scope, $elm, attrs) {
var idToScroll = attrs.href;
$elm.on('click', function() {
var $target;
if (idToScroll) {
$target = $(idToScroll);
} else {
$target = $elm;
}
$("body").animate({scrollTop: $target.offset().top}, "slow");
});
}
}
});
Then you could use it like this: <div scroll-on-click></div>
to scroll to the element clicked. Or <a scroll-on-click href="#element-id"></div>
to scroll to element with the id.
Sure, call the java executable.
Mine is C:\Program Files\Java\jre6\bin\java.exe

As @weichsel stated, CGFloat is just a typedef for either float
or double
. You can see for yourself by Command-double-clicking on "CGFloat" in Xcode — it will jump to the CGBase.h header where the typedef is defined. The same approach is used for NSInteger and NSUInteger as well.
These types were introduced to make it easier to write code that works on both 32-bit and 64-bit without modification. However, if all you need is float
precision within your own code, you can still use float
if you like — it will reduce your memory footprint somewhat. Same goes for integer values.
I suggest you invest the modest time required to make your app 64-bit clean and try running it as such, since most Macs now have 64-bit CPUs and Snow Leopard is fully 64-bit, including the kernel and user applications. Apple's 64-bit Transition Guide for Cocoa is a useful resource.
In case you're looking for it, like me - meanwhile there's a nice and safe JQuery method.
https://api.jquery.com/jquery.parsehtml/
You can f.ex. type this in your console:
var x = "test &";
> undefined
$.parseHTML(x)[0].textContent
> "test &"
So $.parseHTML(x) returns an array, and if you have HTML markup within your text, the array.length will be greater than 1.
You only need to use LoadLibrary if you want to late bind and only resolve the imported functions at runtime. The easiest way to use a third party dll is to link against a .lib.
In reply to your edit:
Yes, the third party API should consist of a dll and/or a lib that contain the implementation and header files that declares the required types. You need to know the type definitions whichever method you use - for LoadLibrary you'll need to define function pointers, so you could just as easily write your own header file instead. Basically, you only need to use LoadLibrary if you want late binding. One valid reason for this would be if you aren't sure if the dll will be available on the target PC.
Use itertools.chain:
itertools.chain(*iterables)
:Make an iterator that returns elements from the first iterable until it is exhausted, then proceeds to the next iterable, until all of the iterables are exhausted. Used for treating consecutive sequences as a single sequence.
from itertools import chain
A = [[1,2], [3,4]]
print list(chain(*A))
# or better: (available since Python 2.6)
print list(chain.from_iterable(A))
The output is:
[1, 2, 3, 4]
[1, 2, 3, 4]
I had the same problem and searched the web for several hours but I couldn't find any solution so I made my own. I wondered why the .net configuration system is so inflexible.
Background: I want to have my DAL.dll to have its own config file for database and DAL settings. I also need the app.config for Enterprise Library and its own configurations. So I need both the app.config and dll.config.
What I did not wanted to do is pass-through every property/setting from the app to my DAL layer!
to bend the "AppDomain.CurrentDomain.SetupInformation.ConfigurationFile" is not possible because I need it for the normal app.config behavior.
My requirements/point of views were:
I came up with modifying the Settings.cs file and implemented a method that opens the ClassLibrary1.dll.config and reads the section information in a private field. After that, I've overriden "this[string propertyName]" so the generated Settings.Desginer.cs calls into my new Property instead of the base class. There the setting is read out of the List.
Finally there is the following code:
internal sealed partial class Settings
{
private List<ConfigurationElement> list;
/// <summary>
/// Initializes a new instance of the <see cref="Settings"/> class.
/// </summary>
public Settings()
{
this.OpenAndStoreConfiguration();
}
/// <summary>
/// Opens the dll.config file and reads its sections into a private List of ConfigurationElement.
/// </summary>
private void OpenAndStoreConfiguration()
{
string codebase = System.Reflection.Assembly.GetExecutingAssembly().CodeBase;
Uri p = new Uri(codebase);
string localPath = p.LocalPath;
string executingFilename = System.IO.Path.GetFileNameWithoutExtension(localPath);
string sectionGroupName = "applicationSettings";
string sectionName = executingFilename + ".Properties.Settings";
string configName = localPath + ".config";
ExeConfigurationFileMap fileMap = new ExeConfigurationFileMap();
fileMap.ExeConfigFilename = configName;
Configuration config = ConfigurationManager.OpenMappedExeConfiguration(fileMap, ConfigurationUserLevel.None);
// read section of properties
var sectionGroup = config.GetSectionGroup(sectionGroupName);
var settingsSection = (ClientSettingsSection)sectionGroup.Sections[sectionName];
list = settingsSection.Settings.OfType<ConfigurationElement>().ToList();
// read section of Connectionstrings
var sections = config.Sections.OfType<ConfigurationSection>();
var connSection = (from section in sections
where section.GetType() == typeof(ConnectionStringsSection)
select section).FirstOrDefault() as ConnectionStringsSection;
if (connSection != null)
{
list.AddRange(connSection.ConnectionStrings.Cast<ConfigurationElement>());
}
}
/// <summary>
/// Gets or sets the <see cref="System.Object"/> with the specified property name.
/// </summary>
/// <value></value>
public override object this[string propertyName]
{
get
{
var result = (from item in list
where Convert.ToString(item.ElementInformation.Properties["name"].Value) == propertyName
select item).FirstOrDefault();
if (result != null)
{
if (result.ElementInformation.Type == typeof(ConnectionStringSettings))
{
return result.ElementInformation.Properties["connectionString"].Value;
}
else if (result.ElementInformation.Type == typeof(SettingElement))
{
return result.ElementInformation.Properties["value"].Value;
}
}
return null;
}
// ignore
set
{
base[propertyName] = value;
}
}
You just will have to copy your ClassLibrary1.dll.config from the ClassLibrary1 output directory to your application's output directory. Perhaps someone will find it useful.

jQuery is an abstraction of JavaScript. Think of jQuery as a sub-set of JavaScript, aimed at working with the DOM. That being said; there are functions for adding item(s) to a collection. I would use basic JavaScript in your case though:
var array;
array[0] = "value1";
array[1] = "value2";
array[2] = "value3";
... Or:
var array = ["value1", "value2", "value3"];
... Or:
var array = [];
array.push("value1");
array.push("value2");
array.push("value3");
Using Hibernate :

org.hibernate.SQLQuery q = (org.hibernate.SQLQuery) session.createSQLQuery("SELECT u.username, u.name, u.email, 'blabla' as passe, login_type as loginType FROM users u").addScalar("username", StringType.INSTANCE).addScalar("name", StringType.INSTANCE).addScalar("email", StringType.INSTANCE).addScalar("passe", StringType.INSTANCE).addScalar("loginType", IntegerType.INSTANCE)
.setResultTransformer(Transformers.aliasToBean(User2DTO.class));
List<User2DTO> userList = q.list();

Use ast.literal_eval to evaluate Python literals. However, what you have is JSON (note "true" for example), so use a JSON deserializer.
>>> import json
>>> s = """{"id":"123456789","name":"John Doe","first_name":"John","last_name":"Doe","link":"http:\/\/www.facebook.com\/jdoe","gender":"male","email":"jdoe\u0040gmail.com","timezone":-7,"locale":"en_US","verified":true,"updated_time":"2011-01-12T02:43:35+0000"}"""
>>> json.loads(s)
{u'first_name': u'John', u'last_name': u'Doe', u'verified': True, u'name': u'John Doe', u'locale': u'en_US', u'gender': u'male', u'email': u'[email protected]', u'link': u'http://www.facebook.com/jdoe', u'timezone': -7, u'updated_time': u'2011-01-12T02:43:35+0000', u'id': u'123456789'}
In Window->Preferences->General->Startup and Shutdown->Workspaces, make sure that 'Prompt for Workspace on startup' is checked.

There is no mistake in your bash script. But you are executing it with sh which has a less extensive syntax ;)
So, run bash ./choose.sh

Wrap the column name in brackets like so, from
becomes [from].
select [from] from table;
It is also possible to use the following (useful when querying multiple tables):
select table.[from] from table;
Here's something that I just wrote along those lines::
#include <random>
#include <chrono>
#include <thread>
using namespace std;

public:
random_device rd;
mt19937 mt;
uniform_real_distribution<double> dist;
backoff_time_t() : rd{}, mt{rd()}, dist{0.5, 1.5} {}
double rand() {
return dist(mt);
}
};
thread_local backoff_time_t backoff_time;
int main(int argc, char** argv) {
double x1 = backoff_time.rand();
double x2 = backoff_time.rand();
double x3 = backoff_time.rand();
double x4 = backoff_time.rand();
return 0;

With a character class this big it is easier to say what you want to keep. A caret in the first position of a character class inverts its sense, so you can write
$varTemp =~ s/[^"%'+\-0-9<=>a-z_{|}]+//gi
or, using the more efficient tr
$varTemp =~ tr/"%'+\-0-9<=>A-Z_a-z{|}//cd
Use the Array#join
method (the argument to join
is what to insert between the strings - in this case a space):
@arr.join(" ")
I found this question when I was looking for the answer to the above question. But in my case the issue was the use of an 'en dash' rather than a 'dash'. Check which dash you are using, it might be the wrong one. I hope this answer speeds up someone else's search, a comment like this could have saved me a bit of time.
Add this to build.gradle file

The function STR_TO_DATE(COLUMN, '%input_format') can do it, you only have to specify the input format. Example : to convert p052011
SELECT STR_TO_DATE('p052011','p%m%Y') FROM your_table;
The result : 2011-05-00
I think you are right by saying that people cannot click half pixels, so personally, I would use rounded jQuery offset...
Variation of the code by Bijaya Bidari that is accepted by Java 8 without warnings in regard with overridable method calls in constructor:

super.setDefaultCloseOperation(EXIT_ON_CLOSE);
jp = new GPanel();
super.add(jp);
}
public static void main(String[] args) {
Graph g1 = new Graph();
g1.setVisible(true);
}
class GPanel extends JPanel {
public GPanel() {
super.setPreferredSize(new Dimension(300, 300));
}
@Override
public void paintComponent(Graphics g) {
super.paintComponent(g);
//rectangle originated at 10,10 and end at 240,240
g.drawRect(10, 10, 240, 240);
//filled Rectangle with rounded corners.
g.fillRoundRect(50, 50, 100, 100, 80, 80);
}
}
}
You have declared your Class as:
@Table( name = "foobar" )

Since no answer is accepted, I would like to provide one possible solution. If your script is written on Windows and uploaded to a Linux server(through FTP), then the problem will raise usually. The reason is that Windows uses CRLF
to end each line while Linux uses LF
. So you should convert it from CRLF
to LF
with the help of an editor, such Atom, as following
If you are on Windows, you just need to do only one step as 'rails restart' and then again type 'rails s' You are good to go.
If I move
CreateUser.py
to the main user_management directory, I can easily use:import Modules.LDAPManager
to importLDAPManager.py
--- this works.
Please, don't. In this way the LDAPManager
module used by CreateUser
will not be the same as the one imported via other imports. This can create problems when you have some global state in the module or during pickling/unpickling. Avoid imports that work only because the module happens to be in the same directory.
When you have a package structure you should either:
Use relative imports, i.e if the CreateUser.py
is in Scripts/
:
from ..Modules import LDAPManager
Note that this was (note the past tense) discouraged by PEP 8 only because old versions of python didn't support them very well, but this problem was solved years ago. The current version of PEP 8 does suggest them as an acceptable alternative to absolute imports. I actually like them inside packages.
Use absolute imports using the whole package name(CreateUser.py
in Scripts/
):
from user_management.Modules import LDAPManager
In order for the second one to work the package user_management
should be installed inside the PYTHONPATH
. During development you can configure the IDE so that this happens, without having to manually add calls to sys.path.append
anywhere.
Also I find it odd that Scripts/
is a subpackage. Because in a real installation the user_management
module would be installed under the site-packages
found in the lib/
directory (whichever directory is used to install libraries in your OS), while the scripts should be installed under a bin/
directory (whichever contains executables for your OS).
In fact I believe Script/
shouldn't even be under user_management
. It should be at the same level of user_management
.
In this way you do not have to use -m
, but you simply have to make sure the package can be found (this again is a matter of configuring the IDE, installing the package correctly or using PYTHONPATH=. python Scripts/CreateUser.py
to launch the scripts with the correct path).
In summary, the hierarchy I would use is:
user_management (package)
|
|------- __init__.py
|
|------- Modules/
| |
| |----- __init__.py
| |----- LDAPManager.py
| |----- PasswordManager.py
|
Scripts/ (*not* a package)
|
|----- CreateUser.py
|----- FindUser.py
Then the code of CreateUser.py
and FindUser.py
should use absolute imports to import the modules:
from user_management.Modules import LDAPManager
During installation you make sure that user_management
ends up somewhere in the PYTHONPATH
, and the scripts inside the directory for executables so that they are able to find the modules. During development you either rely on IDE configuration, or you launch CreateUser.py
adding the Scripts/
parent directory to the PYTHONPATH
(I mean the directory that contains both user_management
and Scripts
):
PYTHONPATH=/the/parent/directory python Scripts/CreateUser.py
Or you can modify the PYTHONPATH
globally so that you don't have to specify this each time. On unix OSes (linux, Mac OS X etc.) you can modify one of the shell scripts to define the PYTHONPATH
external variable, on Windows you have to change the environmental variables settings.
Addendum I believe, if you are using python2, it's better to make sure to avoid implicit relative imports by putting:
from __future__ import absolute_import
at the top of your modules. In this way import X
always means to import the toplevel module X
and will never try to import the X.py
file that's in the same directory (if that directory isn't in the PYTHONPATH
). In this way the only way to do a relative import is to use the explicit syntax (the from . import X
), which is better (explicit is better than implicit).
This will make sure you never happen to use the "bogus" implicit relative imports, since these would raise an ImportError
clearly signalling that something is wrong. Otherwise you could use a module that's not what you think it is.
I think it doesn't, except that a multiline string isn't processed. However, most, if not all Python IDEs have a shortkey for 'commenting out' multiple lines of code.
Happen with me because I ran git config core.autocrlf true
and I forgot to rever back.
After that, when I checkout/pull new code, all LF (break line in Unix) was replaced by CRLF (Break line in Windows).
I ran linter, and all error messages are Expected linebreaks to be 'LF' but found 'CRLF'
To fix the issue, I checked autocrlf
value by running git config --list | grep autocrlf
and I got:
core.autocrlf=true
core.autocrlf=false
I edited the global GIT config ~/.gitconfig
and replaced autocrlf = true
by autocrlf = false
.
After that, I went to my project and do the following (assuming the code in src/
folder):
CURRENT_BRANCH=$(git branch | grep \* | cut -d ' ' -f2);
rm -rf src/*
git checkout $CURRENT_BRANCH src/
To get that file use the below code.
include(Mage::getBaseDir('skin').'myfunc.php');
But it is not a correct way. To add your custom functions you can use the below file.
app/code/core/Mage/core/functions.php
Kindly avoid to use the PHP function under skin dir.
This is the way (I was thinking it's impossible):
First give the table only vertical border-spacing (for example 5px) and set it's horizontal border-spacing to 0. Then you should give proper borders to each row cell. For example the right-most cell in each row should have border on top, bottom and right. The left-most cells should have border on top, bottom and left. And the other cells between these 2 should only have border on top and bottom. Like this example:
<table style="border-spacing:0 5px; color:black">
<tr>
<td style="border-bottom:thin black solid; border-top:thin black solid; border-left:thin black solid;">left-most cell</td>
<td style="border-bottom:thin black solid; border-top:thin black solid;">other cell</td>
<td style="border-bottom:thin black solid; border-top:thin black solid;">other cell</td>
<td style="border-bottom:thin black solid; border-top:thin black solid;">other cell</td>
<td style="border-bottom:thin black solid; border-top:thin black solid; border-right:thin black solid;">right-most cell</td>
</tr>
<tr>
<td style="border-bottom:thin black solid; border-top:thin black solid; border-left:thin black solid;">left-most cell</td>
<td style="border-bottom:thin black solid; border-top:thin black solid;">other cell</td>
<td style="border-bottom:thin black solid; border-top:thin black solid;">other cell</td>
<td style="border-bottom:thin black solid; border-top:thin black solid;">other cell</td>
<td style="border-bottom:thin black solid; border-top:thin black solid; border-right:thin black solid;">right-most cell</td>
</tr>
<tr>
<td style="border-bottom:thin black solid; border-top:thin black solid; border-left:thin black solid;">left-most cell</td>
<td style="border-bottom:thin black solid; border-top:thin black solid;">other cell</td>
<td style="border-bottom:thin black solid; border-top:thin black solid;">other cell</td>
<td style="border-bottom:thin black solid; border-top:thin black solid;">other cell</td>
<td style="border-bottom:thin black solid; border-top:thin black solid; border-right:thin black solid;">right-most cell</td>
</tr>

Step 1: Restart VS Code as an adminstrator
(click the windows key, search for "Visual Studio Code", right click, and you'll see the administrator option)
Step 2: In your VS code powershell terminal run Set-ExecutionPolicy Unrestricted
Just include #import "myProject-Swift.h" in .m or .h file
P.S You will not find "myProject-Swift.h" in file inspector it's hidden. But it is generated by app automatically.
If you want this type of code to run in IE11 (which does not support much of ES6 at all), then you need to get a 3rd party promise library (like Bluebird), include that library and change your coding to use ES5 coding structures (no arrow functions, no let
, etc...) so you can live within the limits of what older browsers support.
Or, you can use a transpiler (like Babel) to convert your ES6 code to ES5 code that will work in older browsers.
Here's a version of your code written in ES5 syntax with the Bluebird promise library:
<script src="https://cdnjs.cloudflare.com/ajax/libs/bluebird/3.3.4/bluebird.min.js"></script>
<script>
'use strict';
var promise = new Promise(function(resolve) {
setTimeout(function() {
resolve("result");
}, 1000);
});
promise.then(function(result) {
alert("Fulfilled: " + result);
}, function(error) {
alert("Rejected: " + error);
});
</script>
Try this to scroll on top

The OP did not exclude the starting variable, so for completeness here is how to handle the generic case of processing a supposed dictionary that may include items as dictionaries.
Also following the pure Python(3.8) recommended way to test for dictionary in the above comments.
from collections.abc import Mapping
dict = {'abc': 'abc', 'def': {'ghi': 'ghi', 'jkl': 'jkl'}}
def parse_dict(in_dict):
if isinstance(in_dict, Mapping):
for k_outer, v_outer in in_dict.items():
if isinstance(v_outer, Mapping):
for k_inner, v_inner in v_outer.items():
print(k_inner, v_inner)

For situations like this, i like to make a deep copy and loop through that copy while modifying the original dict.
If the lookup field is within a list, you can enumerate in the for loop of the list and then specify the position as index to access the field in the original dict.
...
for(int i=0;i<3;i++){ //Rows
for(int j=0;j<5;j++){ //Cols
printf("%<...>\t",var);
}
printf("\n");
}
...
considering that <...> would be d,e,f,s,c... etc datatype... X)
Combining my initial idea and your answers I reached what seems to be the solution to my own question:
public ProducerDTO findAndRemove(String pod) {
ProducerDTO p = null;
try {
p = IntStream.range(0, producersProcedureActive.size())
.filter(i -> producersProcedureActive.get(i).getPod().equals(pod))
.boxed()
.findFirst()
.map(i -> producersProcedureActive.remove((int)i))
.get();
logger.debug(p);
} catch (NoSuchElementException e) {
logger.error("No producer found with POD [" + pod + "]");
}
return p;
}
It lets remove the object using remove(int)
that do not traverse again the
list (as suggested by @Tunaki) and it lets return the removed object to
the function caller.
I read your answers that suggest me to choose safe methods like ifPresent
instead of get
but I do not find a way to use them in this scenario.
Are there any important drawback in this kind of solution?
Edit following @Holger advice
This should be the function I needed
public ProducerDTO findAndRemove(String pod) {
return IntStream.range(0, producersProcedureActive.size())
.filter(i -> producersProcedureActive.get(i).getPod().equals(pod))
.boxed()
.findFirst()
.map(i -> producersProcedureActive.remove((int)i))
.orElseGet(() -> {
logger.error("No producer found with POD [" + pod + "]");
return null;
});
}
JSONObject json = new JSONObject();
json.put("fromZIPCode","123456");
JSONObject json1 = new JSONObject();
json1.put("fromZIPCode","123456");
sList.add(json1);
sList.add(json);
System.out.println(sList);
Output will be
[{"fromZIPCode":"123456"},{"fromZIPCode":"123456"}]

I use ,
as a leader key and ,a
shortcut does the trick
Add this line if you prefer ,a
shortcut
map <Leader>a :%y+<CR>
I use Ctrl y
shortcut to copy
vmap <C-y> y:call system("xclip -i -selection clipboard", getreg("\""))<CR>:call system("xclip -i", getreg("\""))<CR>
And ,v
to paste
nmap <Leader>v :call setreg("\"",system("xclip -o -selection clipboard"))<CR>p
Before using this you have to install xclip
$ sudo apt-get install xclip
Edit: When you use :%y+
, it can be only pasted to Vim vim Ctrl+Insert
shortcut.
And
map <C-a> :%y+<Esc>
is not conflicting any settings in my Vimrc.
As in Swift 3.x for upload image with parameter we can use below alamofire upload method-
static func uploadImageData(inputUrl:String,parameters:[String:Any],imageName: String,imageFile : UIImage,completion:@escaping(_:Any)->Void) {
let imageData = UIImageJPEGRepresentation(imageFile , 0.5)
Alamofire.upload(multipartFormData: { (multipartFormData) in
multipartFormData.append(imageData!, withName: imageName, fileName: "swift_file\(arc4random_uniform(100)).jpeg", mimeType: "image/jpeg")
for key in parameters.keys{
let name = String(key)
if let val = parameters[name!] as? String{
multipartFormData.append(val.data(using: .utf8)!, withName: name!)
}
}
}, to:inputUrl)
{ (result) in
switch result {
case .success(let upload, _, _):
upload.uploadProgress(closure: { (Progress) in
})
upload.responseJSON { response in
if let JSON = response.result.value {
completion(JSON)
}else{
completion(nilValue)
}
}
case .failure(let encodingError):
completion(nilValue)
}
}
}
Note: Additionally if our parameter is array of key-pairs then we can use
var arrayOfKeyPairs = [[String:Any]]()
let json = try? JSONSerialization.data(withJSONObject: arrayOfKeyPairs, options: [.prettyPrinted])
let jsonPresentation = String(data: json!, encoding: .utf8)
Valid regex tokens vary by implementation. A generic form is:
[0-9]+(\.[0-9][0-9]?)?
More compact:
\d+(\.\d{1,2})?
Both assume that both have at least one digit before and one after the decimal place.
To require that the whole string is a number of this form, wrap the expression in start and end tags such as (in Perl's form):
^\d+(\.\d{1,2})?$
To match numbers without a leading digit before the decimal (.12
) and whole numbers having a trailing period (12.
) while excluding input of a single period (.
), try the following:
^(\d+(\.\d{0,2})?|\.?\d{1,2})$
Wrapped the fractional portion in ()?
to make it optional. Be aware that this excludes forms such as 12.
Including that would be more like ^\d+\\.?\d{0,2}$
.
Use ^\d{1,6}(\.\d{1,2})?$
to stop repetition and give a restriction to whole part of the decimal value.
If you can't use a public/private keys, you can use expect:
#!/usr/bin/expect
spawn rsync SRC DEST
expect "password:"
send "PASS\n"
expect eof
if [catch wait] {
puts "rsync failed"
exit 1
}
exit 0
You will need to replace SRC and DEST with your normal rsync source and destination parameters, and replace PASS with your password. Just make sure this file is stored securely!
Fileformat.info is a pretty good reference for this stuff. In your case, it's already in hex, so the hex value is f066
. So you'd do:
content: "\f066";
Try this
$("#postcontent").submit(function() {
return false;
};
$('#postsubmit').click(function(){
// your ajax request here
});
All you need to do is make an array of fields and then set it to the class you want like shown below.
Field fld[] = (class name).class.getDeclaredFields();
for(Field x : fld)
{System.out.println(x);}
For example if you did
Field fld[] = Integer.class.getDeclaredFields();
for(Field x : fld)
{System.out.println(x);}
you would get
public static final int java.lang.Integer.MIN_VALUE
public static final int java.lang.Integer.MAX_VALUE
public static final java.lang.Class java.lang.Integer.TYPE
static final char[] java.lang.Integer.digits
static final char[] java.lang.Integer.DigitTens
static final char[] java.lang.Integer.DigitOnes
static final int[] java.lang.Integer.sizeTable
private static java.lang.String java.lang.Integer.integerCacheHighPropValue
private final int java.lang.Integer.value
public static final int java.lang.Integer.SIZE
private static final long java.lang.Integer.serialVersionUID
An extension of @John Doe & @user3270492's answer. But, this seems to work for me.
<your_secret_command>; history -d $((HISTCMD-1))
You should not see the entry of the command in your history.
Here's the explanation..
The 'history -d' deletes the mentioned entry from the history.
The HISTCMD stores the command_number of the one to be executed next. So, (HISTCMD-1) refers to the last executed command.
For those who are on SunOS which is non-GNU, the following code will help:
sed '1d' test.dat > tmp.dat
Add a column to your existing data to get rid of the hour:minute:second time stamp on each row:
=DATE(YEAR(A1), MONTH(A1), DAY(A1))
Extend this down the length of your data. Even easier: quit collecting the hh:mm:ss data if you don't need it. Assuming your date/time was in column A, and your value was in column B, you'd put the above formula in column C, and auto-extend it for all your data.
Now, in another column (let's say E), create a series of dates corresponding to each day of the specific month you're interested in. Just type the first date, (for example, 10/7/2016 in E1), and auto-extend. Then, in the cell next to the first date, F1, enter:
=SUMIF(C:C, E1, B:B )
autoextend the formula to cover every date in the month, and you're done. Begin at 1/1/2016, and auto-extend for the whole year if you like.
Of course! jQuery is just a library that utilizes javascript after all.
You can use document.getElementById to get the element in question, then change its height accordingly, through element.style.height.
elementToChange = document.getElementById('collapseableEl');
elementToChange.style.height = '100%';
Wrap that up in a neat little function that caters for toggling back and forth and you have yourself a solution.
As others have suggested that you should look into MERGE statement but nobody provided a solution using it I'm adding my own answer with this particular TSQL construct. I bet you'll like it.
Your code has a typo in your if
statement in not exists(select...)
part. Inner select
statement has only one where
condition while UserName condition is excluded from the not exists
due to invalid brace completion. In any case you cave too many closing braces.
I assume this based on the fact that you're using two where
conditions in update
statement later on in your code.
Let's continue to my answer...
MERGE statement is a beautiful TSQL gem very well suited for "insert or update" situations. In your case it would look similar to the following code. Take into consideration that I'm declaring variables what are likely stored procedure parameters (I suspect).
declare @clockDate date = '08/10/2012';
declare @userName = 'test';
merge Clock as target
using (select @clockDate, @userName) as source (ClockDate, UserName)
on (target.ClockDate = source.ClockDate and target.UserName = source.UserName)
when matched then
update
set BreakOut = getdate()
when not matched then
insert (ClockDate, UserName, BreakOut)
values (getdate(), source.UserName, getdate());
Another commonly used option is to pass environment variables. In your code you read them via ENV['VAR']
, and can pass them right before the rake
command, like
$ VAR=foo rake mytask
Think about expectations.
As a client app, you expect to know if something goes wrong on the server side. If the server needs to throw an error when blah
is missing or the requestedResource
value is incorrect than a 400 error would be appropriate.
My answer is an amalgamation of the above two with extension to drawing sphere of user-defined opacity and some annotation. It finds application in b-vector visualization on a sphere for magnetic resonance image (MRI). Hope you find it useful:
from mpl_toolkits.mplot3d import Axes3D
import matplotlib.pyplot as plt
import numpy as np
fig = plt.figure()
ax = fig.gca(projection='3d')
# draw sphere
u, v = np.mgrid[0:2*np.pi:50j, 0:np.pi:50j]
x = np.cos(u)*np.sin(v)
y = np.sin(u)*np.sin(v)
z = np.cos(v)
# alpha controls opacity
ax.plot_surface(x, y, z, color="g", alpha=0.3)
# a random array of 3D coordinates in [-1,1]
bvecs= np.random.randn(20,3)
# tails of the arrows
tails= np.zeros(len(bvecs))
# heads of the arrows with adjusted arrow head length
ax.quiver(tails,tails,tails,bvecs[:,0], bvecs[:,1], bvecs[:,2],
length=1.0, normalize=True, color='r', arrow_length_ratio=0.15)
ax.set_xlabel('X-axis')
ax.set_ylabel('Y-axis')
ax.set_zlabel('Z-axis')
ax.set_title('b-vectors on unit sphere')
plt.show()
A correct way of iterating over the vector and printing its values is as follows:
#include<vector>
// declare the vector of type int
vector<int> v;
// insert elements in the vector
for (unsigned int i = 0; i < 5; ++i){
v.push_back(i);
}
// print those elements
for (auto it = v.begin(); it != v.end(); ++it){
std::cout << *it << std::endl;
}
But at least in the present case it is nicer to use a range-based for loop:
for (auto x: v) std::cout << x << "\n";
(You may also add &
after auto
to make x
a reference to the elements rather than a copy of them. It is then very similar to the above iterator-based approach, but easier to read and write.)
Another way to look at it is to consider git rebase master
as:
Rebase the current branch on top of
master
Here , 'master
' is the upstream branch, and that explain why, during a rebase, ours
and theirs
are reversed.
Here It is actually returning tuple
.
If you execute this code in Python 3:
def get():
a = 3
b = 5
return a,b
number = get()
print(type(number))
print(number)
Output :
<class 'tuple'>
(3, 5)
But if you change the code line return [a,b]
instead of return a,b
and execute :
def get():
a = 3
b = 5
return [a,b]
number = get()
print(type(number))
print(number)
Output :
<class 'list'>
[3, 5]
It is only returning single object which contains multiple values.
There is another alternative to return
statement for returning multiple values, use yield
( to check in details see this What does the "yield" keyword do in Python?)
Sample Example :
def get():
for i in range(5):
yield i
number = get()
print(type(number))
print(number)
for i in number:
print(i)
Output :
<class 'generator'>
<generator object get at 0x7fbe5a1698b8>

Cocoa doesn’t provide anything called abstract. We can create a class abstract which gets checked only at runtime, and at compile time this is not checked.
If it is Rails 5, because of new hash notation:
params.permit(:name, groundtruth: [:type, coordinates:[]])
will work fine.
Before actually answering your question:
Parameters in a URL (e.g. key=listOfUsers/user1
) are GET
parameters and you shouldn't be using them for POST
requests. A quick explanation of the difference between GET and POST can be found here.
In your case, to make use of REST principles, you should probably have:
http://ip:5000/users
http://ip:5000/users/<user_id>
Then, on each URL, you can define the behaviour of different HTTP methods (GET
, POST
, PUT
, DELETE
). For example, on /users/<user_id>
, you want the following:
GET /users/<user_id> - return the information for <user_id>
POST /users/<user_id> - modify/update the information for <user_id> by providing the data
PUT - I will omit this for now as it is similar enough to `POST` at this level of depth
DELETE /users/<user_id> - delete user with ID <user_id>
So, in your example, you want do a POST
to /users/user_1
with the POST data being "John"
. Then the XPath expression or whatever other way you want to access your data should be hidden from the user and not tightly couple to the URL. This way, if you decide to change the way you store and access data, instead of all your URL's changing, you will simply have to change the code on the server-side.
Now, the answer to your question: Below is a basic semi-pseudocode of how you can achieve what I mentioned above:
from flask import Flask
from flask import request
app = Flask(__name__)
@app.route('/users/<user_id>', methods = ['GET', 'POST', 'DELETE'])
def user(user_id):
if request.method == 'GET':
"""return the information for <user_id>"""
.
.
.
if request.method == 'POST':
"""modify/update the information for <user_id>"""
# you can use <user_id>, which is a str but could
# changed to be int or whatever you want, along
# with your lxml knowledge to make the required
# changes
data = request.form # a multidict containing POST data
.
.
.
if request.method == 'DELETE':
"""delete user with ID <user_id>"""
.
.
.
else:
# POST Error 405 Method Not Allowed
.
.
.
There are a lot of other things to consider like the POST
request content-type but I think what I've said so far should be a reasonable starting point. I know I haven't directly answered the exact question you were asking but I hope this helps you. I will make some edits/additions later as well.
Thanks and I hope this is helpful. Please do let me know if I have gotten something wrong.
IF you are checking one variable against multiple condition then you would use something like this Here the block of code where the condition is true will be executed and other blocks will be ignored.
IF(@Var1 Condition1)
BEGIN
/*Your Code Goes here*/
END
ELSE IF(@Var1 Condition2)
BEGIN
/*Your Code Goes here*/
END
ELSE --<--- Default Task if none of the above is true
BEGIN
/*Your Code Goes here*/
END
If you are checking conditions against multiple variables then you would have to go for multiple IF Statements, Each block of code will be executed independently from other blocks.
IF(@Var1 Condition1)
BEGIN
/*Your Code Goes here*/
END
IF(@Var2 Condition1)
BEGIN
/*Your Code Goes here*/
END
IF(@Var3 Condition1)
BEGIN
/*Your Code Goes here*/
END
After every IF statement if there are more than one statement being executed you MUST put them in BEGIN..END Block. Anyway it is always best practice to use BEGIN..END blocks
Update
Found something in your code some BEGIN END you are missing
ELSE IF(@ID IS NOT NULL AND @ID in (SELECT ID FROM Places)) -- Outer Most Block ELSE IF
BEGIN
SELECT @MyName = Name ...
...Some stuff....
IF(SOMETHNG_1) -- IF
--BEGIN
BEGIN TRY
UPDATE ....
END TRY
BEGIN CATCH
SELECT ERROR_MESSAGE() AS 'Message'
RETURN -1
END CATCH
-- END
ELSE IF(SOMETHNG_2) -- ELSE IF
-- BEGIN
BEGIN TRY
UPDATE ...
END TRY
BEGIN CATCH
SELECT ERROR_MESSAGE() AS 'Message'
RETURN -1
END CATCH
-- END
ELSE -- ELSE
BEGIN
BEGIN TRY
UPDATE ...
END TRY
BEGIN CATCH
SELECT ERROR_MESSAGE() AS 'Message'
RETURN -1
END CATCH
END
--The above works I then insert this below and these if statement become nested----
IF(@A!= @SA)
BEGIN
exec Store procedure
@FIELD = 15,
... more params...
END
IF(@S!= @SS)
BEGIN
exec Store procedure
@FIELD = 10,
... more params...
This is what I tried for a right outer join [as per my requirement]:
m1 <- merge(x=companies, y=rounds2, by.x=companies$permalink,
by.y=rounds2$company_permalink, all.y=TRUE)
# Error in fix.by(by.x, x) : 'by' must specify uniquely valid columns
m1 <- merge(x=companies, y=rounds2, by.x=c("permalink"),
by.y=c("company_permalink"), all.y=TRUE)
This worked.

Press Shift + F12 to find all references.
The HTML
<a href="#" id="btn">click</a>
And the javascript
// get a cross-browser function for adding events, place this in [global] or somewhere you can access it
var on = (function(){
if (window.addEventListener) {
return function(target, type, listener){
target.addEventListener(type, listener, false);
};
}
else {
return function(object, sEvent, fpNotify){
object.attachEvent("on" + sEvent, fpNotify);
};
}
}());
// find the element
var el = document.getElementById("btn");
// add the first listener
on(el, "click", function(){
alert("foo");
});
// add the second listener
on(el, "click", function(){
alert("bar");
});
This will alert both 'foo' and 'bar' when clicked.
You can't use a foreach statement for that. The foreach is using internally an iterator:
The iterators returned by this class's iterator and listIterator methods are fail-fast: if the list is structurally modified at any time after the iterator is created, in any way except through the iterator's own remove or add methods, the iterator will throw a ConcurrentModificationException.
(From ArrayList javadoc)
In the foreach statement you don't have access to the iterator's add method and in any case that's still not the type of add that you want because it does not append at the end. You'll need to traverse the list manually:
int listSize = list.size();
for(int i = 0; i < listSize; ++i)
list.add("whatever");
Note that this is only efficient for Lists that allow random access. You can check for this feature by checking whether the list implements the RandomAccess marker interface. An ArrayList has random access. A linked list does not.
Trying to open multiple panels of a collapse control that is setup as an accordion i.e. with the data-parent
attribute set, can prove quite problematic and buggy (see this question on multiple panels open after programmatically opening a panel)
Instead, the best approach would be to:
To allow each panel to toggle individually, on the data-toggle="collapse"
element, set the data-target
attribute to the .collapse
panel ID selector (instead of setting the data-parent
attribute to the parent control. You can read more about this in the question Modify Twitter Bootstrap collapse plugin to keep accordions open.
Roughly, each panel should look like this:
<div class="panel panel-default">
<div class="panel-heading">
<h4 class="panel-title"
data-toggle="collapse"
data-target="#collapseOne">
Collapsible Group Item #1
</h4>
</div>
<div id="collapseOne"
class="panel-collapse collapse">
<div class="panel-body"></div>
</div>
</div>
To manually enforce the accordion behavior, you can create a handler for the collapse show event which occurs just before any panels are displayed. Use this to ensure any other open panels are closed before the selected one is shown (see this answer to multiple panels open). You'll also only want the code to execute when the panels are active. To do all that, add the following code:
$('#accordion').on('show.bs.collapse', function () {
if (active) $('#accordion .in').collapse('hide');
});
Then use show
and hide
to toggle the visibility of each of the panels and data-toggle
to enable and disable the controls.
$('#collapse-init').click(function () {
if (active) {
active = false;
$('.panel-collapse').collapse('show');
$('.panel-title').attr('data-toggle', '');
$(this).text('Enable accordion behavior');
} else {
active = true;
$('.panel-collapse').collapse('hide');
$('.panel-title').attr('data-toggle', 'collapse');
$(this).text('Disable accordion behavior');
}
});
This method is very simple and you can modify your clone without modify the original array.

We can say like DispatcherServlet
taking care of everything in Spring MVC.
At web container start up:
DispatcherServlet
will be loaded and initialized by calling
init()
methodinit()
of DispatcherServlet
will try to identify the Spring
Configuration Document with naming conventions like
"servlet_name-servlet.xml"
then all beans can be identified.Example:
public class DispatcherServlet extends HttpServlet {
ApplicationContext ctx = null;
public void init(ServletConfig cfg){
// 1. try to get the spring configuration document with default naming conventions
String xml = "servlet_name" + "-servlet.xml";
//if it was found then creates the ApplicationContext object
ctx = new XmlWebApplicationContext(xml);
}
...
}
So, in generally DispatcherServlet
capture request URI and hand over to HandlerMapping
. HandlerMapping
search mapping bean with method of controller, where controller returning logical name(view). Then this logical name is send to DispatcherServlet
by HandlerMapping
. Then DispatcherServlet
tell ViewResolver
to give full location of view by appending prefix and suffix, then DispatcherServlet
give view to the client.
I use an i5 processor with 4Gb RAM. It works very well. I feel this is the minimum configuration required to run both eclipse and android avd simultaneously. Just an old processor with high RAM is not sufficient.
To expand on @Andrew Whitaker's answer above, you can convert your tooltip to html entities within the title tag so as to avoid putting raw html directly in your attributes:
$('div').tooltip({_x000D_
content: function () {_x000D_
return $(this).prop('title');_x000D_
}_x000D_
});
_x000D_
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>_x000D_
<script src="http://code.jquery.com/ui/1.9.2/jquery-ui.js"></script>_x000D_
<div class="tooltip" title="<div>check out these kool <i>italics</i> and this <span style="color:red">red text</span></div>">Hover Here</div>
_x000D_
More often than not, the tooltip is stored in a php variable anyway so you'd only need:
<div title="<?php echo htmlentities($tooltip); ?>">Hover Here</div>
You can override by enabling Password less authentication. But you should install keys (pub, priv) before going for that.
Execute the following commands at local server.
Local $> ssh-keygen -t rsa
Press ENTER for all options prompted. No values need to be typed.
Local $> cd .ssh
Local $> scp .ssh/id_rsa.pub user@targetmachine:
Prompts for pwd$> ENTERPASSWORD
Connect to remote server using the following command
Local $> ssh user@targetmachine
Prompts for pwd$> ENTERPASSWORD
Execute the following commands at remote server
Remote $> mkdir .ssh
Remote $> chmod 700 .ssh
Remote $> cat id_rsa.pub >> .ssh/authorized_keys
Remote $> chmod 600 .ssh/authorized_keys
Remote $> exit
Execute the following command at local server to test password-less authentication. It should be connected without password.
$> ssh user@targetmachine
Confirmed.

I needed something to print things out nicely and separate the bits every n-bit. In other words display the leading zeros and show something like this:
n = 5463
output = 0000 0000 0000 0000 0001 0101 0101 0111
So here's what I wrote:
/**
* Converts an integer to a 32-bit binary string
* @param number
* The number to convert
* @param groupSize
* The number of bits in a group
* @return
* The 32-bit long bit string
*/
public static String intToString(int number, int groupSize) {
StringBuilder result = new StringBuilder();
for(int i = 31; i >= 0 ; i--) {
int mask = 1 << i;
result.append((number & mask) != 0 ? "1" : "0");
if (i % groupSize == 0)
result.append(" ");
}
result.replace(result.length() - 1, result.length(), "");
return result.toString();
}
Invoke it like this:
public static void main(String[] args) {
System.out.println(intToString(5463, 4));
}
I would suggest you use TryParse
:
Console.WriteLine("1. Add account.");
Console.WriteLine("Enter choice: ");
string input = Console.ReadLine();
int number;
Int32.TryParse(input, out number);
This way, your application does not throw an exception, if you try to parse something like "1q" or "23e", because somebody made a faulty input.
Int32.TryParse
returns a boolean value, so you can use it in an if
statement, to see whether or not you need to branch of your code:
int number;
if(!Int32.TryParse(input, out number))
{
//no, not able to parse, repeat, throw exception, use fallback value?
}
To your question: You will not find a solution to read an integer because ReadLine()
reads the whole command line, threfor returns a string. What you can do is, try to convert this input into and int16/32/64 variable.
There are several methods for this:
If you are in doubt about the input, which is to be converted, always go for the TryParse methods, no matter if you try to parse strings, int variable or what not.
Update In C# 7.0 out variables can be declared directly where they are passed in as an argument, so the above code could be condensed into this:
if(Int32.TryParse(input, out int number))
{
/* Yes input could be parsed and we can now use number in this code block
scope */
}
else
{
/* No, input could not be parsed to an integer */
}
A complete example would look like this:
class Program
{
static void Main(string[] args)
{
Console.WriteLine("Hello World!");
var foo = Console.ReadLine();
if (int.TryParse(foo, out int number1)) {
Console.WriteLine($"{number1} is a number");
}
else
{
Console.WriteLine($"{foo} is not a number");
}
Console.WriteLine($"The value of the variable {nameof(number1)} is {number1}");
Console.ReadLine();
}
}
Here you can see, that the variable number1
does get initialized even if the input is not a number and has the value 0 regardless, so it is valid even outside the declaring if block
This one works better if you don't have the python on path or want to specify the directory :
//for Windows
npm config set python C:\Python27\python.exe
//for Linux
npm config set python /usr/bin/python27

I think the better answer for this questions is
array_diff()
because it Compares array against one or more other arrays and returns the values in array that are not present in any of the other arrays.
Whereas
array_intersect() returns an array containing all the values of array that are present in all the arguments. Note that keys are preserved.
The proxies
' dict syntax is {"protocol":"ip:port", ...}
. With it you can specify different (or the same) proxie(s) for requests using http, https, and ftp protocols:
http_proxy = "http://10.10.1.10:3128"
https_proxy = "https://10.10.1.11:1080"
ftp_proxy = "ftp://10.10.1.10:3128"
proxyDict = {
"http" : http_proxy,
"https" : https_proxy,
"ftp" : ftp_proxy
}
r = requests.get(url, headers=headers, proxies=proxyDict)
Deduced from the requests
documentation:
Parameters:
method
– method for the new Request object.
url
– URL for the new Request object.
...
proxies
– (optional) Dictionary mapping protocol to the URL of the proxy.
...
On linux you can also do this via the HTTP_PROXY
, HTTPS_PROXY
, and FTP_PROXY
environment variables:
export HTTP_PROXY=10.10.1.10:3128
export HTTPS_PROXY=10.10.1.11:1080
export FTP_PROXY=10.10.1.10:3128
On Windows:
set http_proxy=10.10.1.10:3128
set https_proxy=10.10.1.11:1080
set ftp_proxy=10.10.1.10:3128
Thanks, Jay for pointing this out:
The syntax changed with requests 2.0.0.
You'll need to add a schema to the url: https://2.python-requests.org/en/latest/user/advanced/#proxies
Imagine you've thread A and thread B. They are both synchronised
on the same object and inside this block there's a global variable they are both updating;
static boolean commonVar = false;
Object lock = new Object;
...
void threadAMethod(){
...
while(commonVar == false){
synchornized(lock){
...
commonVar = true
}
}
}
void threadBMethod(){
...
while(commonVar == true){
synchornized(lock){
...
commonVar = false
}
}
}
So, when thread A enters in the while
loop and holds the lock, it does what it has to do and set the commonVar
to true
. Then thread B comes in, enters in the while
loop and since commonVar
is true
now, it is be able to hold the lock. It does so, executes the synchronised
block, and sets commonVar
back to false
. Now, thread A again gets it's new CPU window, it was about to quit the while
loop but thread B has just set it back to false
, so the cycle repeats over again. Threads do something (so they're not blocked in the traditional sense) but for pretty much nothing.
It maybe also nice to mention that livelock does not necessarily have to appear here. I'm assuming that the scheduler favours the other thread once the synchronised
block finish executing. Most of the time, I think it's a hard-to-hit expectation and depends on many things happening under the hood.
In MySQL -> INT(10) does not mean a 10-digit number, it means an integer with a display width of 10 digits. The maximum value for an INT in MySQL is 2147483647 (or 4294967295 if unsigned).
You can use a BIGINT instead of INT to store it as a numeric. Using BIGINT will save you 3 bytes per row over VARCHAR(10).
If you want to Store "Country + area + number separately". Try using a VARCHAR(20). This allows you the ability to store international phone numbers properly, should that need arise.
Use collectl
which has extensive process I/O monitoring including monitoring threads.
Be warned that there are I/O counters for I/O being written to cache and I/O going to disk. collectl
reports them separately. If you're not careful you can misinterpret the data. See http://collectl.sourceforge.net/Process.html
Of course, it shows a lot more than just process stats because you'd want one tool to provide everything rather than a bunch of different one that displays everything in different formats, right?
Here is how I made a script that could take either command line inputs or have a text file redirected.
if ($#ARGV < 1) {
@ARGV = ();
@ARGV = <>;
chomp(@ARGV);
}
This will reassign the contents of the file to @ARGV, from there you just process @ARGV as if someone was including command line options.
WARNING
If no file is redirected, the program will sit their idle because it is waiting for input from STDIN.
I have not figured out a way to detect if a file is being redirected in yet to eliminate the STDIN issue.
I would use JTidy - it is simlar to JSoup, but I don't know JSoup well. JTidy handles broken HTML and returns a w3c Document, so you can use this as a source to XSLT to extract the content you are really interested in. If you don't know XSLT, then you might as well go with JSoup, as the Document model is nicer to work with than w3c.
EDIT: A quick look on the JSoup website shows that JSoup may indeed be the better choice. It seems to support CSS selectors out the box for extracting stuff from the document. This may be a lot easier to work with than getting into XSLT.

you can use the UNION ALL
keyword for this.
Here is the MSDN doc to do it in T-SQL http://msdn.microsoft.com/en-us/library/ms180026.aspx
UNION ALL - combines the result set
UNION- Does something like a Set Union and doesnt output duplicate values
For the difference with an example: http://sql-plsql.blogspot.in/2010/05/difference-between-union-union-all.html
This is Java. You have to make your own tailored Pair class with descriptive class and field names, and not to mind that you will reinvent the wheel by writing hashCode()/equals() or implementing Comparable again and again.
Python string comparison is lexicographic:
From Python Docs: http://docs.python.org/reference/expressions.html
Strings are compared lexicographically using the numeric equivalents (the result of the built-in function ord()) of their characters. Unicode and 8-bit strings are fully interoperable in this behavior.
Hence in your example, 'abc' < 'bac'
, 'a' comes before (less-than) 'b' numerically (in ASCII and Unicode representations), so the comparison ends right there.
I guess this can be due to many things. In my case it was having "WHERE id IN" condition in my query and I was setting IDs separated by dash as a string using setString method on PreparedStatement.
Not sure if there is better way to do this but I just added placeholder in my statement and replaced it by values on my own.

Update (2016):
If you only need SOAP client, there is well maintained library called zeep. It supports both Python 2 and 3 :)
Update:
Additionally to what is mentioned above, I will refer to Python WebServices page which is always up-to-date with all actively maintained and recommended modules to SOAP and all other webservice types.
Unfortunately, at the moment, I don't think there is a "best" Python SOAP library. Each of the mainstream ones available has its own pros and cons.
Older libraries:
SOAPy: Was the "best," but no longer maintained. Does not work on Python 2.5+
ZSI: Very painful to use, and development is slow. Has a module called "SOAPpy", which is different than SOAPy (above).
"Newer" libraries:
SUDS: Very Pythonic, and easy to create WSDL-consuming SOAP clients. Creating SOAP servers is a little bit more difficult. (This package does not work with Python3. For Python3 see SUDS-py3)
SUDS-py3: The Python3 version of SUDS
spyne: Creating servers is easy, creating clients a little bit more challenging. Documentation is somewhat lacking.
ladon: Creating servers is much like in soaplib (using a decorator). Ladon exposes more interfaces than SOAP at the same time without extra user code needed.
pysimplesoap: very lightweight but useful for both client and server - includes a web2py server integration that ships with web2py.
Of the above, I've only used SUDS personally, and I liked it a lot.
This should do it, let me know if you have trouble with it:
Sub foo()
Dim x As Workbook
Dim y As Workbook
'## Open both workbooks first:
Set x = Workbooks.Open(" path to copying book ")
Set y = Workbooks.Open(" path to destination book ")
'Now, copy what you want from x:
x.Sheets("name of copying sheet").Range("A1").Copy
'Now, paste to y worksheet:
y.Sheets("sheetname").Range("A1").PasteSpecial
'Close x:
x.Close
End Sub
Alternatively, you could just:
Sub foo2()
Dim x As Workbook
Dim y As Workbook
'## Open both workbooks first:
Set x = Workbooks.Open(" path to copying book ")
Set y = Workbooks.Open(" path to destination book ")
'Now, transfer values from x to y:
y.Sheets("sheetname").Range("A1").Value = x.Sheets("name of copying sheet").Range("A1")
'Close x:
x.Close
End Sub
To extend this to the entire sheet:
With x.Sheets("name of copying sheet").UsedRange
'Now, paste to y worksheet:
y.Sheets("sheet name").Range("A1").Resize( _
.Rows.Count, .Columns.Count) = .Value
End With
And yet another way, store the value as a variable and write the variable to the destination:
Sub foo3()
Dim x As Workbook
Dim y As Workbook
Dim vals as Variant
'## Open both workbooks first:
Set x = Workbooks.Open(" path to copying book ")
Set y = Workbooks.Open(" path to destination book ")
'Store the value in a variable:
vals = x.Sheets("name of sheet").Range("A1").Value
'Use the variable to assign a value to the other file/sheet:
y.Sheets("sheetname").Range("A1").Value = vals
'Close x:
x.Close
End Sub
The last method above is usually the fastest for most applications, but do note that for very large datasets (100k rows) it's observed that the Clipboard actually outperforms the array dump:
Copy/PasteSpecial vs Range.Value = Range.Value
That said, there are other considerations than just speed, and it may be the case that the performance hit on a large dataset is worth the tradeoff, to avoid interacting with the Clipboard.
The easiest way is to use lubridate:
library(lubridate)
prods.all$Date2 <- mdy(prods.all$Date2)
This function automatically returns objects of class POSIXct
and will work with either factors or characters.

Therefore you should always register an error handler to catch those things (as @tidbeck suggested).
At first, I advice you to take a look at the documentation for the MediaPlayer
class and get an understanding of what that with states means. See: http://developer.android.com/reference/android/media/MediaPlayer.html#StateDiagram
Your mistake here could well be one of the common ones, the others wrote here, but in general, I would take a look at the documentation of what methods are valid to call in what state: http://developer.android.com/reference/android/media/MediaPlayer.html#Valid_and_Invalid_States
In my example it was the method mediaPlayer.CurrentPosition
, that I called while the media player was in a state, where it was not allowed to call this property.
Typeface tf = Typeface.createFromAsset(getAssets(),
"fonts/DroidSansFallback.ttf");
TextView tv = (TextView) findViewById(R.id.CustomFontText);
tv.setTypeface(tf);
Input masks can be implemented using a combination of the keyup
event, and the HTMLInputElement
value
, selectionStart
, and selectionEnd
properties. Here's a very simple implementation which does some of what you want. It's certainly not perfect, but works well enough to demonstrate the principle:
Array.prototype.forEach.call(document.body.querySelectorAll("*[data-mask]"), applyDataMask);_x000D_
_x000D_
function applyDataMask(field) {_x000D_
var mask = field.dataset.mask.split('');_x000D_
_x000D_
// For now, this just strips everything that's not a number_x000D_
function stripMask(maskedData) {_x000D_
function isDigit(char) {_x000D_
return /\d/.test(char);_x000D_
}_x000D_
return maskedData.split('').filter(isDigit);_x000D_
}_x000D_
_x000D_
// Replace `_` characters with characters from `data`_x000D_
function applyMask(data) {_x000D_
return mask.map(function(char) {_x000D_
if (char != '_') return char;_x000D_
if (data.length == 0) return char;_x000D_
return data.shift();_x000D_
}).join('')_x000D_
}_x000D_
_x000D_
function reapplyMask(data) {_x000D_
return applyMask(stripMask(data));_x000D_
}_x000D_
_x000D_
function changed() { _x000D_
var oldStart = field.selectionStart;_x000D_
var oldEnd = field.selectionEnd;_x000D_
_x000D_
field.value = reapplyMask(field.value);_x000D_
_x000D_
field.selectionStart = oldStart;_x000D_
field.selectionEnd = oldEnd;_x000D_
}_x000D_
_x000D_
field.addEventListener('click', changed)_x000D_
field.addEventListener('keyup', changed)_x000D_
}
_x000D_
ISO Date: <input type="text" value="____-__-__" data-mask="____-__-__"/><br/>_x000D_
Telephone: <input type="text" value="(___) ___-____" data-mask="(___) ___-____"/><br/>
_x000D_
There are also a number of libraries out there which perform this function. Some examples include:
for the GitLab Enterprise Edition 9.3.0
By default, master branch is protected so unprotect :)
1-Select you "project"
2-Select "Repository"
3-Select "branches"
4-Select "Project Settings"
5-In "Protected Branches" click to "expand"
6-and after click in "unprotect" button
If you have installed wordpress using apt, the config files are split in multiple directories. In that case you need to run:
sudo chown -R -h www-data:www-data /var/lib/wordpress/wp-content/
sudo chown -R -h www-data:www-data /usr/share/wordpress/wp-content/
The -h
switch changes the permissions for symlinks as well, otherwise they are not removable by user www-data
I found you can do this easily via the Cloud Flare service.
Set up a bucket, enable webhosting on the bucket and point the desired CNAME to that endpoint via Cloudflare... and pay for the service of course... but $5-$20 VS $600 is much easier to stomach.

Today things have changed a little.
Now we avoid use ProgressDialog to show spinning progress:
If you want to put in your app a spinning progress you should use an Activity indicators:

A general solution to convert from byte array to string when you don't know the encoding:
static string BytesToStringConverted(byte[] bytes)
{
using (var stream = new MemoryStream(bytes))
{
using (var streamReader = new StreamReader(stream))
{
return streamReader.ReadToEnd();
}
}
}
