(Swift 4.2 Xcode 11) Simple to use Extension:-
extension Double {
func round(to places: Int) -> Double {
let divisor = pow(10.0, Double(places))
return (self * divisor).rounded() / divisor
}
}
Use:-
if let distanceDb = Double(strDistance) {
cell.lblDistance.text = "\(distanceDb.round(to:2)) km"
}
Noneof the answers worked for me, I was getting "'HttpRequestBase' does not contain a definition for 'Query'", but this did work:
HttpContext.Current.Request.QueryString["index"]
This is default by iOS7 design. try to do the below:
[tableView setSeparatorInset:UIEdgeInsetsMake(0, 0, 0, 0)];
You can set the 'Separator Inset' from the storyboard:
If you want to get classes of div and then want to check if any class exists then simple use.
if ( $('#div-id' ).hasClass( 'classname' ) ) {
// do something...
}
e.g;
if ( $('body').hasClass( 'home' ) ) {
$('#menu-item-4').addClass('active');
}
It is possible to specify null
as field value in native sql.
@Query(value = "select p.id, p.uid, p.title, null as documentation, p.ptype " +
" from projects p " +
"where p.uid = (:uid)" +
" and p.ptype = 'P'", nativeQuery = true)
Project findInfoByUid(@Param("uid") String uid);
The difference in assignment operators is clearer when you use them to set an argument value in a function call. For example:
median(x = 1:10)
x
## Error: object 'x' not found
In this case, x
is declared within the scope of the function, so it does not exist in the user workspace.
median(x <- 1:10)
x
## [1] 1 2 3 4 5 6 7 8 9 10
In this case, x
is declared in the user workspace, so you can use it after the function call has been completed.
There is a general preference among the R community for using <-
for assignment (other than in function signatures) for compatibility with (very) old versions of S-Plus. Note that the spaces help to clarify situations like
x<-3
# Does this mean assignment?
x <- 3
# Or less than?
x < -3
Most R IDEs have keyboard shortcuts to make <-
easier to type. Ctrl + = in Architect, Alt + - in RStudio (Option + - under macOS), Shift + - (underscore) in emacs+ESS.
If you prefer writing =
to <-
but want to use the more common assignment symbol for publicly released code (on CRAN, for example), then you can use one of the tidy_*
functions in the formatR
package to automatically replace =
with <-
.
library(formatR)
tidy_source(text = "x=1:5", arrow = TRUE)
## x <- 1:5
The answer to the question "Why does x <- y = 5
throw an error but not x <- y <- 5
?" is "It's down to the magic contained in the parser". R's syntax contains many ambiguous cases that have to be resolved one way or another. The parser chooses to resolve the bits of the expression in different orders depending on whether =
or <-
was used.
To understand what is happening, you need to know that assignment silently returns the value that was assigned. You can see that more clearly by explicitly printing, for example print(x <- 2 + 3)
.
Secondly, it's clearer if we use prefix notation for assignment. So
x <- 5
`<-`(x, 5) #same thing
y = 5
`=`(y, 5) #also the same thing
The parser interprets x <- y <- 5
as
`<-`(x, `<-`(y, 5))
We might expect that x <- y = 5
would then be
`<-`(x, `=`(y, 5))
but actually it gets interpreted as
`=`(`<-`(x, y), 5)
This is because =
is lower precedence than <-
, as shown on the ?Syntax
help page.

It's important to point out that all of the above solutions map the port to every interface on your machine. This is less than desirable if you have a public IP address, or your machine has an IP on a large network. Your application may be exposed to a much wider audience than you'd hoped.
redis:
build:
context:
dockerfile: Dockerfile-redis
ports:
- "127.0.0.1:3901:3901"
127.0.0.1
is the ip address that maps to the hostname localhost
on your machine. So now your application is only exposed over that interface and since 127.0.0.1
is only accessible via your machine, you're not exposing your containers to the entire world.
The documentation explains this further and can be found here: https://docs.docker.com/compose/compose-file/#ports
Note: If you're using Docker for mac this will make the container listen on 127.0.0.1 on the Docker for Mac VM and will not be accessible from your localhost. If I recall correctly.
Connection.Response resp = Jsoup.connect(url) //
.timeout(20000) //
.method(Connection.Method.GET) //
.execute();
actually, the error occurs when you have slow internet so try to maximize the timeout time and then your code will definitely work as it works for me.

You can now simply do Instant.parse("2015-04-28T14:23:38.521Z")
and get the correct thing now, especially since you should be using Instant
instead of the broken java.util.Date
with the most recent versions of Java.
You should be using DateTimeFormatter
instead of SimpleDateFormatter
as well.
The explanation below is still valid as as what the format represents. But it was written before Java 8 was ubiquitous so it uses the old classes that you should not be using if you are using Java 8 or higher.
Z
as demonstrated:In the pattern the
T
is escaped with'

as documented in the JavaDoc forSimpleDateFormat

is the marker for the oldTimeZone
information as well.

For Windows if you dont want to edit pb_gba.conf ie leave the method to MD5(default), create a new user, by running this query in Query tool in PGadmin
CREATE USER admin WITH PASSWORD 'secret'
then in cmd
psql "dbname=Main_db host=127.0.0.1 user=admin password=secret port=5432
where dbname is your db in postgresql
Versions of sed
that support the -i
option for editing a file in place write to a temporary file and then rename the file.
Alternatively, you can just use ed
. For example, to change all occurrences of foo
to bar
in the file file.txt
, you can do:
echo ',s/foo/bar/g; w' | tr \; '\012' | ed -s file.txt
Syntax is similar to sed
, but certainly not exactly the same.
Even if you don't have a -i
supporting sed
, you can easily write a script to do the work for you. Instead of sed -i 's/foo/bar/g' file
, you could do inline file sed 's/foo/bar/g'
. Such a script is trivial to write. For example:
#!/bin/sh
IN=$1
shift
trap 'rm -f "$tmp"' 0
tmp=$( mktemp )
<"$IN" "$@" >"$tmp" && cat "$tmp" > "$IN" # preserve hard links
should be adequate for most uses.
Is there use case you can provide?
Anywhere you want to store an object name for use by database maintenance scripts. For example, a script purges old rows from certain tables that have a date column. It's configured with a table that gives table name, column name to filter on, and how many days of history to keep. Another script dumps certain tables to CSV files, and again is configured with a table listing the tables to dump. These configuration tables can use the sysname
type to store table and column names.
This must be a bug with Chrome (Version 56.0.2924.87), but the below fixes the bluriness for me when changing css properties in the console('.0'). I'll report it.

Transact-SQL is a bit more tricky that C# or C++ try/catch blocks, because of the added complexity of transactions. A CATCH block has to check the xact_state() function and decide whether it can commit or has to rollback. I have covered the topic in my blog and I have an article that shows how to correctly handle transactions in with a try catch block, including possible nested transactions: Exception handling and nested transactions.
create procedure [usp_my_procedure_name]
as
begin
set nocount on;
declare @trancount int;
set @trancount = @@trancount;
begin try
if @trancount = 0
begin transaction
else
save transaction usp_my_procedure_name;
-- Do the actual work here
lbexit:
if @trancount = 0
commit;
end try
begin catch
declare @error int, @message varchar(4000), @xstate int;
select @error = ERROR_NUMBER(),
@message = ERROR_MESSAGE(), @xstate = XACT_STATE();
if @xstate = -1
rollback;
if @xstate = 1 and @trancount = 0
rollback
if @xstate = 1 and @trancount > 0
rollback transaction usp_my_procedure_name;
raiserror ('usp_my_procedure_name: %d: %s', 16, 1, @error, @message) ;
return;
end catch
end
distcp command use for copying from one cluster to another cluster in parallel. You have to set the path for namenode of src and path for namenode of dst, internally it use mapper.
Example:
$ hadoop distcp <src> <dst>
there few options you can set for distcp
-m for no. of mapper for copying data this will increase speed of copying.
-atomic for auto commit the data.
-update will only update data that is in old version.
There are generic command for copying files in hadoop are -cp and -put but they are use only when the data volume is less.
Should be xpath with not contains() method, //production[not(contains(category,'business'))]
If INSERTS
are rare, I would avoid doing a NOT EXISTS (...)
since it emits a SELECT
on all updates. Instead, take a look at wildpeaks answer: https://dba.stackexchange.com/questions/5815/how-can-i-insert-if-key-not-exist-with-postgresql
CREATE OR REPLACE FUNCTION upsert_tableName(arg1 type, arg2 type) RETURNS VOID AS $$
DECLARE
BEGIN
UPDATE tableName SET col1 = value WHERE colX = arg1 and colY = arg2;
IF NOT FOUND THEN
INSERT INTO tableName values (value, arg1, arg2);
END IF;
END;
$$ LANGUAGE 'plpgsql';
This way Postgres will initially try to do a UPDATE
. If no rows was affected, it will fall back to emitting an INSERT
.

This should work in your case without removing namespaces:
XmlNode idNode = myXmlDoc.GetElementsByTagName("id")[0];
def is_nil_and_zero(data)
data.blank? || data == 0
end
If we pass "" it will return false whereas blank? returns true. Same is the case when data = false blank? returns true for nil, false, empty, or a whitespace string. So it's better to use blank? method to avoid empty string as well.
Try this:
MyContext Context = new MyContext();
Context.YourEntity.Add(obj);
Context.SaveChanges();
int ID = obj._ID;
Also possible with vanilla JS
new Date().toISOString() // "2017-08-26T16:31:02.349Z"
I can't find anything that deals with clock times exactly, so I'd just use some functions from package:lubridate and work with seconds-since-midnight:
require(lubridate)
clockS = function(t){hour(t)*3600+minute(t)*60+second(t)}
plot(clockS(times),val)
You might then want to look at some of the axis code to figure out how to label axes nicely.
This doesn't require a permission.
val intent = Intent(Intent.ACTION_DIAL, Uri.parse("tel:+123456"))
startActivity(intent)
Or
val intent = Intent(Intent.ACTION_DIAL, Uri.fromParts("tel", "+123456", null))
startActivity(intent)
But it shows one more dialog (asking whether you want to call phone just once or always). So it would be better to use ACTION_CALL
with a permission (see Revoked permission android.permission.CALL_PHONE).
The inspect module provides several useful functions to help get information about live objects such as modules, classes, methods, functions, tracebacks, frame objects, and code objects.
Using getmembers()
you can see all attributes of your class, along with their value. To exclude private or protected attributes use .startswith('_')
. To exclude methods or functions use inspect.ismethod()
or inspect.isfunction()
.
import inspect
class NewClass(object):
def __init__(self, number):
self.multi = int(number) * 2
self.str = str(number)
def func_1(self):
pass
a = NewClass(2)
for i in inspect.getmembers(a):
# Ignores anything starting with underscore
# (that is, private and protected attributes)
if not i[0].startswith('_'):
# Ignores methods
if not inspect.ismethod(i[1]):
print(i)
Note that ismethod()
is used on the second element of i
since the first is simply a string (its name).
Offtopic: Use CamelCase for class names.
You can't float or set the width of an inline element. Remove display: inline;
from both classes and your markup should present fine.
EDIT: You can set the width, but it will cause the element to be rendered as a block.
The simple way to do it. All you need is to put the decorator method outside the class. You can still use it inside.
def my_decorator(func):
#this is the key line. There's the aditional self parameter
def wrap(self, *params, **kwargs):
# you can use self here as if you were inside the class
return func()
return wrap
class Test(object):
@my_decorator
def bar(self):
pass

You can find the entire stack trace using browser specific code. The good thing is someone already made it; here is the project code on GitHub.
But not all the news is good:
It is really slow to get the stack trace so be careful (read this for more).
You will need to define function names for the stack trace to be legible. Because if you have code like this:
var Klass = function kls() {
this.Hello = function() { alert(printStackTrace().join('\n\n')); };
}
new Klass().Hello();
Google Chrome will alert ... kls.Hello ( ...
but most browsers will expect a function name just after the keyword function
and will treat it as an anonymous function. An not even Chrome will be able to use the Klass
name if you don't give the name kls
to the function.
And by the way, you can pass to the function printStackTrace the option {guess: true}
but I didn't find any real improvement by doing that.
Not all browsers give you the same information. That is, parameters, code column, etc.
By the way, if you only want the name of the caller function (in most browsers, but not IE) you can use:
arguments.callee.caller.name
But note that this name will be the one after the function
keyword. I found no way (even on Google Chrome) to get more than that without getting the code of the whole function.
And summarizing the rest of the best answers (by Pablo Cabrera, nourdine, and Greg Hewgill). The only cross-browser and really safe thing you can use is:
arguments.callee.caller.toString();
Which will show the code of the caller function. Sadly, that is not enough for me, and that is why I give you tips for the StackTrace and the caller function Name (although they are not cross-browser).
There are standard statistical functions and methods for finding outliers to data, which is probably what you need in the first case. Using derivatives would solve your second. I'm not sure for a method which solves both continuous functions and sampled data, however.
Well, actually I'll have to say David is right with his solution, but there are some topics disturbing me:
ViewModel
, and include the Model as member in the ViewModel
, then you effectively sent your model to the View => this is BADSo how can you create a better coupling?
I would use a tool like AutoMapper
or ValueInjecter to map between ViewModel
and Model.
AutoMapper
does seem to have the better syntax and feel to it, but the current version lacks a
very severe topic: It is not able to perform the mapping from ViewModel
to Model (under certain circumstances like flattening, etc., but this is off topic)
So at present I prefer to use ValueInjecter
.
So you create a ViewModel
with the fields you need in the view.
You add the SelectList items you need as lookups.
And you add them as SelectLists already. So you can query from a LINQ enabled sourc, select the ID and text field and store it as a selectlist:
You gain that you do not have to create a new type (dictionary) as lookup and you just move the new SelectList
from the view to the controller.
// StaffTypes is an IEnumerable<StaffType> from dbContext
// viewModel is the viewModel initialized to copy content of Model Employee
// viewModel.StaffTypes is of type SelectList
viewModel.StaffTypes =
new SelectList(
StaffTypes.OrderBy( item => item.Name )
"StaffTypeID",
"Type",
viewModel.StaffTypeID
);
In the view you just have to call
@Html.DropDownListFor( model => mode.StaffTypeID, model.StaffTypes )
Back in the post element of your method in the controller you have to take a parameter of the type of your ViewModel
. You then check for validation.
If the validation fails, you have to remember to re-populate the viewModel.StaffTypes
SelectList, because this item will be null on entering the post function.
So I tend to have those population things separated into a function.
You just call back return new View(viewModel)
if anything is wrong.
Validation errors found by MVC3 will automatically be shown in the view.
If you have your own validation code you can add validation errors by specifying which field they belong to. Check documentation on ModelState
to get info on that.
If the viewModel
is valid you have to perform the next step:
If it is a create of a new item, you have to populate a model from the viewModel
(best suited is ValueInjecter
). Then you can add it to the EF collection of that type and commit changes.
If you have an update, you get the current db item first into a model. Then you can copy the values from the viewModel
back to the model (again using ValueInjecter
gets you do that very quick).
After that you can SaveChanges
and are done.
Feel free to ask if anything is unclear.
I have another possible answer for those wondering why event log entries are not showing up in the History tab of Task Scheduler for certain tasks, even though All Task History is enabled, the events for those tasks are viewable in the Event Log, and all other tasks show history just fine. In my case, I had created 13 new tasks. For 5 of them, events showed fine under History, but for the other 8, the History tab was completely blank. I even verified these tasks were enabled for history individually (and logging events) using Mick Wood's post about using the Event Viewer.
Then it hit me. I suddenly realized what all 8 had in common that the other 5 did not. They all had an ampersand (&) character in the event name. I created them by exporting the first task I created, "Sync E to N", renaming the exported file name, editing the XML contents, and then importing the new task. Windows Explorer happily let me rename the task, for example, to "Sync C to N & T", and Task Scheduler happily let me import it. However, with that pesky "&" in the name, it could not retrieve its history from the event log. When I deleted the original event, renamed the xml file to "Sync C to N and T", and imported it, voila, there were all of the log entries in the History tab in Task Scheduler.
In a Ruby on Rails application (especially with something like the Prawn gem and the Prawnto Rails plugin), you can accomplish this a little more simply than a full on script (like the previous PHP example).
In your controller:
def index
respond_to do |format|
format.html # Your HTML view
format.pdf { render :layout => false }
end
end
The render :layout => false part tells the browser to open up the "Would you like to download this file?" prompt instead of attempting to render the PDF. Then you would be able to link to the file normally: http://mysite.com/myawesomepdf.pdf
$objPHPExcel
->getActiveSheet()
->getStyle('A1')
->getFill()
->getStartColor()
->getRGB();
// 09/28/2015
System.out.println(new SimpleDateFormat("MM/dd/yyyy").format(Calendar.getInstance().getTime()));
// Mon Sep 28
System.out.println( new Date().toString().substring(0, 10) );
// 2015-09-28
System.out.println(new java.sql.Date(System.currentTimeMillis()));
// 2015-09-28
// java 8
System.out.println( LocalDate.now(ZoneId.of("Europe/Paris")) ); // rest zones id in ZoneId class
Presumably, if one wants to use an OnTouchListener
rather than an OnClickListener
, then the extra functionality of the OnTouchListener
is needed. This is a supplemental answer to show more detail of how an OnTouchListener
can be used.
Define the listener
Put this somewhere in your activity or fragment.
private View.OnTouchListener handleTouch = new View.OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
int x = (int) event.getX();
int y = (int) event.getY();
switch (event.getAction()) {
case MotionEvent.ACTION_DOWN:
Log.i("TAG", "touched down");
break;
case MotionEvent.ACTION_MOVE:
Log.i("TAG", "moving: (" + x + ", " + y + ")");
break;
case MotionEvent.ACTION_UP:
Log.i("TAG", "touched up");
break;
}
return true;
}
};
Set the listener
Set the listener in onCreate
(for an Activity) or onCreateView
(for a Fragment).
myView.setOnTouchListener(handleTouch);
Notes
getX
and getY
give you the coordinates relative to the view (that is, the top left corner of the view). They will be negative when moving above or to the left of your view. Use getRawX
and getRawY
if you want the absolute screen coordinates.x
and y
values to determine things like swipe direction.For me adding AppRoutingModule to my imports solved the problem.
imports: [
BrowserModule,
AppRoutingModule,
RouterModule.forRoot([
{
path: 'new-cmp',
component: NewCmpComponent

OK so, picture the scenario I was just in:
You attempt a merge
, or maybe a cherry-pick
, and you're stopped with
$ git cherry-pick 1023e24
error: could not apply 1023e24... [Commit Message]
hint: after resolving the conflicts, mark the corrected paths
hint: with 'git add <paths>' or 'git rm <paths>'
hint: and commit the result with 'git commit'
Now, you view the conflicted file and you really don't want to keep your changes. In my case above, the file was conflicted on just a newline my IDE had auto-added. To undo your changes and accept their's, the easiest way is:
git checkout --theirs path/to/the/conflicted_file.php
git add path/to/the/conflicted_file.php
The converse of this (to overwrite the incoming version with your version) is
git checkout --ours path/to/the/conflicted_file.php
git add path/to/the/conflicted_file.php
Surprisingly, I couldn't find this answer very easily on the Net.
You can use Notepad++ to evaluate a file's encoding without needing to write code. The evaluated encoding of the open file will display on the bottom bar, far right side. The encodings supported can be seen by going to Settings -> Preferences -> New Document/Default Directory
and looking in the drop down.
You can use outline with outline offset
<div class="double-border"></div>
.double-border{
background-color:#ccc;
outline: 1px solid #f00;
outline-offset: 3px;
}
Quite frankly I would say use a library that does what you need (like platform.js for example). At some point things will change and the library will be equipped for those changes and manual parsing using regular expressions will fail.

Combining Alaa Akoum and Nick Eagle's solutions allowed me to loop through a series of windows services and stop them if they're running.
# stop the following Windows services in the specified order:
[Array] $Services = 'Service1','Service2','Service3','Service4','Service5';
# loop through each service, if its running, stop it
foreach($ServiceName in $Services)
{
$arrService = Get-Service -Name $ServiceName
write-host $ServiceName
while ($arrService.Status -eq 'Running')
{
Stop-Service $ServiceName
write-host $arrService.status
write-host 'Service stopping'
Start-Sleep -seconds 60
$arrService.Refresh()
if ($arrService.Status -eq 'Stopped')
{
Write-Host 'Service is now Stopped'
}
}
}
The same can be done to start a series of service if they are not running:
# start the following Windows services in the specified order:
[Array] $Services = 'Service1','Service2','Service3','Service4','Service5';
# loop through each service, if its not running, start it
foreach($ServiceName in $Services)
{
$arrService = Get-Service -Name $ServiceName
write-host $ServiceName
while ($arrService.Status -ne 'Running')
{
Start-Service $ServiceName
write-host $arrService.status
write-host 'Service starting'
Start-Sleep -seconds 60
$arrService.Refresh()
if ($arrService.Status -eq 'Running')
{
Write-Host 'Service is now Running'
}
}
}
If you're using JPA1, you might have to drop a persistence.xml
file in there which specifies the name of a persistence-unit you might want to use. A persistence-unit provides a convenient way of specifying a set of metadata files, and classes, and jars that contain all classes to be persisted in a grouping.
import javax.persistence.EntityManagerFactory;
import javax.persistence.Persistence;
// ...
EntityManagerFactory emf =
Persistence.createEntityManagerFactory(persistenceUnitName);

The typical formula for recalculation of 2D array indices into 1D array index is
index = indexX * arrayWidth + indexY;
Alternatively you can use
index = indexY * arrayHeight + indexX;
(assuming that arrayWidth
is measured along X axis, and arrayHeight
along Y axis)
Of course, one can come up with many different formulae that provide alternative unique mappings, but normally there's no need to.
In C/C++ languages built-in multidimensional arrays are stored in memory so that the last index changes the fastest, meaning that for an array declared as
int xy[10][10];
element xy[5][3]
is immediately followed by xy[5][4]
in memory. You might want to follow that convention as well, choosing one of the above two formulae depending on which index (X or Y) you consider to be the "last" of the two.
If you want to pass the variable to your proxy backend, you have to set it with the proxy module.
location / {
proxy_pass http://example.com;
proxy_set_header Host example.com;
proxy_set_header HTTP_Country-Code $geoip_country_code;
proxy_pass_request_headers on;
}
And now it's passed to the proxy backend.
declare @data as varchar(50)
set @data='ciao335'
--get text
Select Left(@Data, PatIndex('%[0-9]%', @Data + '1') - 1) ---->>ciao
--get numeric
Select right(@Data, len(@data) - (PatIndex('%[0-9]%', @Data )-1) ) ---->>335
Using dataset with default values is one way, but you must use query for Available values and for Default Values, if values are hard coded in Available values tab, then you must define default values as expressions. Pictures should explain everything
Create Parameter (if not automaticly created)
Define values - wrong way example
Define values - correct way example
Set default values - you must define all default values reflecting available values to make "Select All" by default, if you won't define all only those defined will be selected by default.
The Result
One picture for Data type: Int
<p style="margin-left:5em;">Lorem ipsum dolor sit amet, consectetur adipiscing elit. Ut lacinia vestibulum quam sit amet aliquet. Phasellus tempor nisi eget tellus venenatis tempus. Aliquam dapibus porttitor convallis. Praesent pretium luctus orci, quis ullamcorper lacus lacinia a. Integer eget molestie purus. Vestibulum porta mollis tempus. Class aptent taciti sociosqu ad litora torquent per conubia nostra, per inceptos himenaeos. </p>
That'll do it, there's a few improvements obviously, but that's the basics. And I use 'em'
as the measurement, you may want to use other units, like 'px'
.
EDIT: What they're describing above is a way of associating groups of styles, or classes, with elements on a web page. You can implement that in a few ways, here's one which may suit you:
In your HTML page, containing the <p>
tagged content from your DB add in a new 'style' node and wrap the styles you want to declare in a class like so:
<head>
<style type="text/css">
p { margin-left:5em; /* Or another measurement unit, like px */ }
</style>
</head>
<body>
<p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Ut lacinia vestibulum quam sit amet aliquet.</p>
</body>
So above, all <p>
elements in your document will have that style rule applied. Perhaps you are pumping your paragraph content into a container of some sort? Try this:
<head>
<style type="text/css">
.container p { margin-left:5em; /* Or another measurement unit, like px */ }
</style>
</head>
<body>
<div class="container">
<p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Ut lacinia vestibulum quam sit amet aliquet.</p>
</div>
<p>Vestibulum porta mollis tempus. Class aptent taciti sociosqu ad litora torquent per conubia nostra.</p>
</body>
In the example above, only the <p>
element inside the div, whose class name is 'container', will have the styles applied - and not the <p>
element outside the container.
In addition to the above, you can collect your styles together and remove the style element from the <head>
tag, replacing it with a <link>
tag, which points to an external CSS file. This external file is where you'd now put your <p>
tag styles. This concept is known as 'seperating content from style' and is considered good practice, and is also an extendible way to create styles, and can help with low maintenance.
The collapse package provides the fastest scale function - implemented in C++ using Welfords Online Algorithm:
dat <- data.frame(x = rnorm(1e6, 30, .2),
y = runif(1e6, 3, 5),
z = runif(1e6, 10, 20))
library(collapse)
library(microbenchmark)
microbenchmark(fscale(dat), scale(dat))
Unit: milliseconds
expr min lq mean median uq max neval cld
fscale(dat) 27.86456 29.5864 38.96896 30.80421 43.79045 313.5729 100 a
scale(dat) 357.07130 391.0914 489.93546 416.33626 625.38561 793.2243 100 b
Furthermore: fscale
is S3 generic for vectors, matrices and data frames and also supports grouped and/or weighted scaling operations, as well as scaling to arbitrary means and standard deviations.
I'll try summarize the great answer by Alex and the jlmendezbonini's point, adding a modification that will make everything ARC compatible (so far it's not since ARC will complain since you should return id
, which means "any object", but BOOL
is not an object type).
- (BOOL) endWorldHunger:(id)largeAmountsOfMonies error:(NSError**)error {
// begin feeding the world's children...
// it's all going well until....
if (ohNoImOutOfMonies) {
// sad, we can't solve world hunger, but we can let people know what went wrong!
// init dictionary to be used to populate error object
NSMutableDictionary* details = [NSMutableDictionary dictionary];
[details setValue:@"ran out of money" forKey:NSLocalizedDescriptionKey];
// populate the error object with the details
if (error != NULL) {
// populate the error object with the details
*error = [NSError errorWithDomain:@"world" code:200 userInfo:details];
}
// we couldn't feed the world's children...return nil..sniffle...sniffle
return NO;
}
// wohoo! We fed the world's children. The world is now in lots of debt. But who cares?
return YES;
}
Now instead of checking for the return value of our method call, we check whether error
is still nil
. If it's not we have a problem.
// initialize NSError object
NSError* error = nil;
// try to feed the world
BOOL success = [self endWorldHunger:smallAmountsOfMonies error:&error];
if (!success) {
// inspect error
NSLog(@"%@", [error localizedDescription]);
}
// otherwise the world has been fed. Wow, your code must rock.
A little hacky, but I created an array called "console", and anytime I wanted to output to console I pushed to the array. Then whenever I wanted to see the actual output, I just returned console
instead of whatever I was returning before.
//return 'console' //uncomment to output console
return "actual output";
}
Here is the simplest and the easiest way to find the position of the clicked item:
I've also faced the same problem.
I wanted to find of the position of the clicked/selected item of the RecyclerView() and perform some specific operations on that particular item.
getAdapterPosition() method works like a charm for these kind of stuff. I found this method after a day of long research and after trying numerous other methods.
int position = getAdapterPosition();
Toast.makeText(this, "Position is: "+position, Toast.LENGTH_SHORT).show();
You do not have to use any extra method. Just create a global variable named 'position' and initialize it with getAdapterPosition() in any of the major method of the adapter (class or similar).
Here is a brief documentation from this link.
getAdapterPosition added in version 22.1.0 int getAdapterPosition () Returns the Adapter position of the item represented by this ViewHolder. Note that this might be different than the getLayoutPosition() if there are pending adapter updates but a new layout pass has not happened yet. RecyclerView does not handle any adapter updates until the next layout traversal. This may create temporary inconsistencies between what user sees on the screen and what adapter contents have. This inconsistency is not important since it will be less than 16ms but it might be a problem if you want to use ViewHolder position to access the adapter. Sometimes, you may need to get the exact adapter position to do some actions in response to user events. In that case, you should use this method which will calculate the Adapter position of the ViewHolder.
Happy to help. Feel free to ask doubts.

ensure_ascii=False really only defers the issue to the decoding stage:

Ultimately you can't store raw bytes in a JSON document, so you'll want to use some means of unambiguously encoding a sequence of arbitrary bytes as an ASCII string - such as base64.

Another solution with pure CSS+HTML and the pseudo-class :lang()
.
Use some HTML to mark up the number with the classes thousands-separator
and decimal-separator
:
<html lang="es">
Spanish: 1<span class="thousands-separator">200</span><span class="thousands-separator">000</span><span class="decimal-separator">.</span>50
</html>
Use the lang
pseudo-class to format the number.
/* Spanish */
.thousands-separator:lang(es):before{
content: ".";
}
.decimal-separator:lang(es){
visibility: hidden;
position: relative;
}
.decimal-separator:lang(es):before{
position: absolute;
visibility: visible;
content: ",";
}
/* English and Mexican Spanish */
.thousands-separator:lang(en):before, .thousands-separator:lang(es-MX):before{
content: ",";
}

If the variable ax.xaxis._autolabelpos = True, matplotlib sets the label position in function _update_label_position in axis.py according to (some excerpts):
bboxes, bboxes2 = self._get_tick_bboxes(ticks_to_draw, renderer)
bbox = mtransforms.Bbox.union(bboxes)
bottom = bbox.y0
x, y = self.label.get_position()
self.label.set_position((x, bottom - self.labelpad * self.figure.dpi / 72.0))
You can set the label position independently of the ticks by using:
ax.xaxis.set_label_coords(x0, y0)
that sets _autolabelpos to False or as mentioned above by changing the labelpad parameter.
If you don't mind a bit more markup, this would work:
<div class="centered">
<button class="btn btn-large btn-primary" type="button">Submit</button>
</div>
With the corresponding CSS rule:
.centered
{
text-align:center;
}
I have to look at the CSS rules for the btn
class, but I don't think it specifies a width, so auto
left & right margins wouldn't work. If you added one of the span
or input-
rules to the button, auto margins would work, though.
Edit:
Confirmed my initial thought; the btn
classes do not have a width defined, so you can't use auto side margins. Also, as @AndrewM notes, you could simply use the text-center
class instead of creating a new ruleset.
This is because .
is a reserved character in regular expression, representing any character.
Instead, we should use the following statement:
String extensionRemoved = filename.split("\\.")[0];
In Chrome when you load a website from some HTTP server both absolute paths (e.g. /images/sth.png
) and relative paths to some upper level directory (e.g. ../images/sth.png
) work.
But!
When you load (in Chrome!) a HTML document from local filesystem you cannot access directories above current directory. I.e. you cannot access ../something/something.sth
and changing relative path to absolute or anything else won't help.
7 in a
Clearest and fastest way to do it.
You can also consider using a set
, but constructing that set from your list may take more time than faster membership testing will save. The only way to be certain is to benchmark well. (this also depends on what operations you require)
Couldn't you use the server variables to do this?
Or would this work?:
unset($_GET['page']);
$url = $_SERVER['SCRIPT_NAME'] ."?".http_build_query($_GET);
Just a thought.
Editor's note: disabling SSL verification has security implications. Without verification of the authenticity of SSL/HTTPS connections, a malicious attacker can impersonate a trusted endpoint such as Gmail, and you'll be vulnerable to a Man-in-the-Middle Attack.

If it is the case that only the IDE indicates that it cannot find included files, but compiling is successful, the issue is simply that IntelliSense is not fully up to date with recent changes. This can happen specifically when including existing projects, in my own experience. Deleting the .sdf file (= IntelliSense database) that is generated in your solution directory forces Visual Studio to regenerate it, so that it is up to date again. Just doing a "clean" will probably do the same thing, but takes more time since everything will be generated again then.

Do you want to disable error reporting, or just prevent the user from seeing it? It’s usually a good idea to log errors, even on a production site.
# in your PHP code:
ini_set('display_errors', '0'); # don't show any errors...
error_reporting(E_ALL | E_STRICT); # ...but do log them
They will be logged to your standard system log, or use the error_log
directive to specify exactly where you want errors to go.
I just read a pretty interesting explanation on the difference between the two, and a growing preference to attach models to the controller and alias the controller to bind models to the view. http://toddmotto.com/digging-into-angulars-controller-as-syntax/ is the article.
NOTE: The original link still exists, but changes in formatting have made it hard to read. It's easier to view in the original.
He doesn't mention it but when defining directives, if you need to share something between multiple directives and don't want a service (there are legitimate cases where services are a hassle) then attach the data to the parent directive's controller.
The $scope
service provides plenty of useful things, $watch
being the most obvious, but if all you need to bind data to the view, using the plain controller and 'controller as' in the template is fine and arguably preferable.
a bit more convoluted solution that fully matches your spec
echo `expr $FILENAME : '\(.*\)\.[^.]*'`_`date +%d-%m-%y`.`expr $FILENAME : '.*\.\([^.]*\)'`
where first 'expr' extracts file name without extension, second 'expr' extracts extension
As Marcelo suggests:
UPDATE mytable
SET new_column = <expr containing old_column>;
If this takes too long and fails due to "snapshot too old" errors (e.g. if the expression queries another highly-active table), and if the new value for the column is always NOT NULL, you could update the table in batches:
UPDATE mytable
SET new_column = <expr containing old_column>
WHERE new_column IS NULL
AND ROWNUM <= 100000;
Just run this statement, COMMIT, then run it again; rinse, repeat until it reports "0 rows updated". It'll take longer but each update is less likely to fail.

A better alternative that should be more efficient is to use the DBMS_PARALLEL_EXECUTE

DBMS_PARALLEL_EXECUTE.CREATE_TASK ('mytask');
-- Chunk the table by ROWID
DBMS_PARALLEL_EXECUTE.CREATE_CHUNKS_BY_ROWID('mytask', 'HR', 'EMPLOYEES', true, 100);
-- Execute the DML in parallel
l_sql_stmt := 'update EMPLOYEES e
SET e.salary = e.salary + 10
WHERE rowid BETWEEN :start_id AND :end_id';
DBMS_PARALLEL_EXECUTE.RUN_TASK('mytask', l_sql_stmt, DBMS_SQL.NATIVE,
parallel_level => 10);
-- If there is an error, RESUME it for at most 2 times.
l_try := 0;
l_status := DBMS_PARALLEL_EXECUTE.TASK_STATUS('mytask');
WHILE(l_try < 2 and l_status != DBMS_PARALLEL_EXECUTE.FINISHED)
LOOP
l_try := l_try + 1;
DBMS_PARALLEL_EXECUTE.RESUME_TASK('mytask');
l_status := DBMS_PARALLEL_EXECUTE.TASK_STATUS('mytask');
END LOOP;
-- Done with processing; drop the task
DBMS_PARALLEL_EXECUTE.DROP_TASK('mytask');

The difference between 'exec' and 'system' is that exec replaces your current program with 'command' and NEVER returns to your program. system, on the other hand, forks and runs 'command' and returns you the exit status of 'command' when it is done running. The back tick runs 'command' and then returns a string representing its standard out (whatever it would have printed to the screen)
You can also use popen to run shell commands and I think that there is a shell module - 'use shell' that gives you transparent access to typical shell commands.
Hope that clarifies it for you.
It's short for Dimension, as it was originally used in BASIC to specify the size of arrays.
DIM — (short for dimension) define the size of arrays
Ref: http://en.wikipedia.org/wiki/Dartmouth_BASIC
A part of the original BASIC compiler source code, where it would jump when finding a DIM
command, in which you can clearly see the original intention for the keyword:
DIM LDA XR01 BACK OFF OBJECT POINTER
SUB N3
STA RX01
LDA L 2 GET VARIABLE TO BE DIMENSIONED
STA 3
LDA S 3
CAB N36 CHECK FOR $ ARRAY
BRU *+7 NOT $
...
Ref: http://dtss.dartmouth.edu/scans/BASIC/BASIC%20Compiler.pdf
Later on it came to be used to declare all kinds of variables, when the possibility to specify the type for variables was added in more recent implementations.
These instructions are for XCode 6.4 (since I couldn't find the update for the recent versions even this was a bit outdated)

Click "+" to add, and then follow the instructions. You will need to open "Keychain Access.app", there under "Keychain Access" menu > "Certificate Assistant>", choose "Request a Certificate From a Certificate Authority" etc.
b) XCode part:
After all, you need to go to XCode, and open XCode>Preferences..., choose your Apple ID > View Details... > click that rounded arrow to update as well as "+" to check for iOS Distribution or iOS Developer Signing Identities.

get it from here. https://github.com/UB-Mannheim/tesseract/wiki
Download the suitable version.
2 - Add Tesseract path to your System Environment. i.e. Edit system variables.
3 - Run pip install pytesseract
and pip install tesseract
4 - Add this line to your python script every time
pytesseract.pytesseract.tesseract_cmd = 'C:/OCR/Tesseract-OCR/tesseract.exe' # your path may be different
5 - Run the code.
Internet Explorer has a new feature since IE9 RC: adding <-loopback>
to the proxy bypass list causes WinInet (the network library used by IE) to send requests destined for localhost
and 127.0.0.1
through the defined proxy.
Here's the original announcement by @EricLaw: http://blogs.msdn.com/b/fiddler/archive/2011/02/10/fiddler-is-better-with-internet-explorer-9.aspx
My solution breaks down in 3 parts: the state of the user is stored in a service, in the run method you watch when the route changes and you check if the user is allowed to access the requested page, in your main controller you watch if the state of the user change.
app.run(['$rootScope', '$location', 'Auth', function ($rootScope, $location, Auth) {
$rootScope.$on('$routeChangeStart', function (event) {
if (!Auth.isLoggedIn()) {
console.log('DENY');
event.preventDefault();
$location.path('/login');
}
else {
console.log('ALLOW');
$location.path('/home');
}
});
}]);
You should create a service (I will name it Auth
) which will handle the user object and have a method to know if the user is logged or not.
service:
.factory('Auth', function(){
var user;
return{
setUser : function(aUser){
user = aUser;
},
isLoggedIn : function(){
return(user)? user : false;
}
}
})
From your app.run
, you should listen the $routeChangeStart
event. When the route will change, it will check if the user is logged (the isLoggedIn
method should handle it). It won't load the requested route if the user is not logged and it will redirect the user to the right page (in your case login).
The loginController
should be used in your login page to handle login. It should just interract with the Auth
service and set the user as logged or not.
loginController:
.controller('loginCtrl', [ '$scope', 'Auth', function ($scope, Auth) {
//submit
$scope.login = function () {
// Ask to the server, do your job and THEN set the user
Auth.setUser(user); //Update the state of the user in the app
};
}])
From your main controller, you could listen if the user state change and react with a redirection.
.controller('mainCtrl', ['$scope', 'Auth', '$location', function ($scope, Auth, $location) {
$scope.$watch(Auth.isLoggedIn, function (value, oldValue) {
if(!value && oldValue) {
console.log("Disconnect");
$location.path('/login');
}
if(value) {
console.log("Connect");
//Do something when the user is connected
}
}, true);
With React >= 16.3 you can use ref and forwardRef, to gain access to child's DOM from its parent. Don't use old way of refs anymore.
Here is the example using your case :
import React, { Component } from 'react';
export default class P extends React.Component {
constructor (props) {
super(props)
this.state = {data: 'test' }
this.onUpdate = this.onUpdate.bind(this)
this.ref = React.createRef();
}
onUpdate(data) {
this.setState({data : this.ref.current.value})
}
render () {
return (
<div>
<C1 ref={this.ref} onUpdate={this.onUpdate}/>
<C2 data={this.state.data}/>
</div>
)
}
}
const C1 = React.forwardRef((props, ref) => (
<div>
<input type='text' ref={ref} onChange={props.onUpdate} />
</div>
));
class C2 extends React.Component {
render () {
return <div>C2 reacts : {this.props.data}</div>
}
}
See Refs and ForwardRef for detailed info about refs and forwardRef.
Here is the way to go:
Runtime rt = Runtime.getRuntime();
String[] commands = {"system.exe", "-get t"};
Process proc = rt.exec(commands);
BufferedReader stdInput = new BufferedReader(new
InputStreamReader(proc.getInputStream()));
BufferedReader stdError = new BufferedReader(new
InputStreamReader(proc.getErrorStream()));
// Read the output from the command
System.out.println("Here is the standard output of the command:\n");
String s = null;
while ((s = stdInput.readLine()) != null) {
System.out.println(s);
}
// Read any errors from the attempted command
System.out.println("Here is the standard error of the command (if any):\n");
while ((s = stdError.readLine()) != null) {
System.out.println(s);
}
Read the Javadoc for more details here. ProcessBuilder
would be a good choice to use.
There is a lot of confusion about these methods, but it is actually not that complicated. Most of the confusion is because:
View/ViewGroup
or any of its children do not return true in
onTouchEvent
, dispatchTouchEvent
and onInterceptTouchEvent
will ONLY
be called for MotionEvent.ACTION_DOWN
. Without a true from
onTouchEvent
, the parent view will assume your view does not need
the MotionEvents.MotionEvent.ACTION_DOWN
, even if your ViewGroup returns true in onTouchEvent
.Processing order is like this:
dispatchTouchEvent
is called.onInterceptTouchEvent
is called for MotionEvent.ACTION_DOWN
or when
any of the children of the ViewGroup returned true in onTouchEvent
.onTouchEvent
is first called on the children of the ViewGroup and
when none of the children returns true it is called on the
View/ViewGroup
.If you want to preview TouchEvents/MotionEvents
without disabling the events on your children, you must do two things:
dispatchTouchEvent
to preview the event and return
super.dispatchTouchEvent(ev)
;onTouchEvent
and return true, otherwise you won’t get any
MotionEvent
except MotionEvent.ACTION_DOWN
.If you want to detect some gesture like a swipe event, without disabling other events on your children as long as you did not detect the gesture, you can do it like this:
onInterceptTouchEvent
when your flag is set to cancel
MotionEvent processing by your children. This is also a convenient
place to reset your flag, because onInterceptTouchEvent won’t be
called again until the next MotionEvent.ACTION_DOWN
.Example of overrides in a FrameLayout
(my example in is C# as I’m programming with Xamarin Android, but the logic is the same in Java):
public override bool DispatchTouchEvent(MotionEvent e)
{
// Preview the touch event to detect a swipe:
switch (e.ActionMasked)
{
case MotionEventActions.Down:
_processingSwipe = false;
_touchStartPosition = e.RawX;
break;
case MotionEventActions.Move:
if (!_processingSwipe)
{
float move = e.RawX - _touchStartPosition;
if (move >= _swipeSize)
{
_processingSwipe = true;
_cancelChildren = true;
ProcessSwipe();
}
}
break;
}
return base.DispatchTouchEvent(e);
}
public override bool OnTouchEvent(MotionEvent e)
{
// To make sure to receive touch events, tell parent we are handling them:
return true;
}
public override bool OnInterceptTouchEvent(MotionEvent e)
{
// Cancel all children when processing a swipe:
if (_cancelChildren)
{
// Reset cancel flag here, as OnInterceptTouchEvent won't be called until the next MotionEventActions.Down:
_cancelChildren = false;
return true;
}
return false;
}
Brief answer to your question: No. You shouldn't call ConfigureAwait(false)
at the application level like that.
TL;DR version of the long answer: If you are writing a library where you don't know your consumer and don't need a synchronization context (which you shouldn't in a library I believe), you should always use ConfigureAwait(false)
. Otherwise, the consumers of your library may face deadlocks by consuming your asynchronous methods in a blocking fashion. This depends on the situation.
Here is a bit more detailed explanation on the importance of ConfigureAwait
method (a quote from my blog post):
When you are awaiting on a method with await keyword, compiler generates bunch of code in behalf of you. One of the purposes of this action is to handle synchronization with the UI (or main) thread. The key component of this feature is the
SynchronizationContext.Current
which gets the synchronization context for the current thread.SynchronizationContext.Current
is populated depending on the environment you are in. TheGetAwaiter
method of Task looks up forSynchronizationContext.Current
. If current synchronization context is not null, the continuation that gets passed to that awaiter will get posted back to that synchronization context.When consuming a method, which uses the new asynchronous language features, in a blocking fashion, you will end up with a deadlock if you have an available SynchronizationContext. When you are consuming such methods in a blocking fashion (waiting on the Task with Wait method or taking the result directly from the Result property of the Task), you will block the main thread at the same time. When eventually the Task completes inside that method in the threadpool, it is going to invoke the continuation to post back to the main thread because
SynchronizationContext.Current
is available and captured. But there is a problem here: the UI thread is blocked and you have a deadlock!
Also, here are two great articles for you which are exactly for your question:
Finally, there is a great short video from Lucian Wischik exactly on this topic: Async library methods should consider using Task.ConfigureAwait(false).
Hope this helps.

The base difference that which already everyone mentioned is that one is heavy weight and other is light weight. Let me explain, basically what the term heavy weight means is that when you're using the awt components the native code used for getting the view component is generated by the Operating System, thats why it the look and feel changes from OS to OS. Where as in swing components its the responsibility of JVM to generate the view for the components. Another statement which i saw is that swing is MVC based and awt is not.
The closest equivalent of C++ std::map<>
(a tree internally) is C# OrderedDictionary<>
(a tree internally), while C# OrderedDictionary<>
is missing some very important methods from C++ std::map<>
, namely: std::map::find
, std::map::lower_bound
, std::map::upper_bound
, std::map::equal_range
, and std::map
iterators
, which are basically the backbone for the previous 4 methods.
Why those 4 methods are important? Because it gives us the ability to locate the "whereabouts" of a given key, in addition to only being able to check if a key exists, or the SortedDictionary is guaranteed to be ordered.
What is "whereabouts" of a key in a std::map
? The key doesn't necessarily have to exist in the collection, we want to know the location the key might be at, usually between two iterators pointing to two adjacent existing keys respectively in the collection, so we can operate on the range the key falls into in a O(logN)
complexity. Without such 4 methods (with iterators), one has to do an O(N)
iteration through the collection every time a range is queried against a key.
On your branch - say master, pull and allow unrelated histories
git pull origin master --allow-unrelated-histories
Worked for me.
$(this).parent().siblings(":first").text()
parent
gives you the <td>
around the link,
siblings
gives all the <td>
tags in that <tr>
,
:first
gives the first matched element in the set.
text()
gives the contents of the tag.
Don't know if it's the best way but I'd do this:
=A1 & TEXT(A2,"mm/dd/yyyy")
That should format your date into your desired string.
Edit: That funny number you saw is the number of days between December 31st 1899 and your date. That's how Excel stores dates.
This is a straightforward way to add items to an R List:
# create an empty list:
small_list = list()
# now put some objects in it:
small_list$k1 = "v1"
small_list$k2 = "v2"
small_list$k3 = 1:10
# retrieve them the same way:
small_list$k1
# returns "v1"
# "index" notation works as well:
small_list["k2"]
Or programmatically:
kx = paste(LETTERS[1:5], 1:5, sep="")
vx = runif(5)
lx = list()
cn = 1
for (itm in kx) { lx[itm] = vx[cn]; cn = cn + 1 }
print(length(lx))
# returns 5
def count_letters(word):
return len(word) - word.count(' ')
Alternatively, if you have multiple letters to ignore, you could filter the string:
def count_letters(word):
BAD_LETTERS = " "
return len([letter for letter in word if letter not in BAD_LETTERS])
This will iterate over all descendant files, not just the immediate children of the directory:
import os
for subdir, dirs, files in os.walk(rootdir):
for file in files:
#print os.path.join(subdir, file)
filepath = subdir + os.sep + file
if filepath.endswith(".asm"):
print (filepath)
I had this edge case, where I checked out a previous version of the code in which my file directory structure was different:
git checkout 1.87.1
warning: unable to unlink web/sites/default/default.settings.php: Permission denied
... other warnings ...
Note: checking out '1.87.1'.
You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by performing another checkout.
If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -b with the checkout command again.
Example:
git checkout -b <new-branch-name>
HEAD is now at 50a7153d7... Merge branch 'hotfix/1.87.1'
In a case like this you may need to use --force (when you know that going back to the original branch and discarding changes is a safe thing to do).
git checkout master
did not work:
$ git checkout master
error: The following untracked working tree files would be overwritten by checkout:
web/sites/default/default.settings.php
... other files ...
git checkout master --force
(or git checkout master -f
) worked:
git checkout master -f
Previous HEAD position was 50a7153d7... Merge branch 'hotfix/1.87.1'
Switched to branch 'master'
Your branch is up-to-date with 'origin/master'.
For example: Add this data-attr to your primary slick div: data-space="7"
$('[data-space]').each(function () {
var $this = $(this),
$space = $this.attr('data-space');
$('.slick-slide').css({
marginLeft: $space + 'px',
marginRight: $space + 'px'
});
$('.slick-list').css({
marginLeft: -$space + 'px',
marginRight: -$space/2 + 'px'
})
});
Yes, you can use GT for free. See the post with explanation. And look at repo on GitHub.
UPD 19.03.2019 Here is a version for browser on GitHub.
ASCII has 128 code positions, allocated to graphic characters and control characters (control codes).
Unicode has 1,114,112 code positions. About 100,000 of them have currently been allocated to characters, and many code points have been made permanently noncharacters (i.e. not used to encode any character ever), and most code points are not yet assigned.
The only things that ASCII and Unicode have in common are: 1) They are character codes. 2) The 128 first code positions of Unicode have been defined to have the same meanings as in ASCII, except that the code positions of ASCII control characters are just defined as denoting control characters, with names corresponding to their ASCII names, but their meanings are not defined in Unicode.
Sometimes, however, Unicode is characterized (even in the Unicode standard!) as “wide ASCII”. This is a slogan that mainly tries to convey the idea that Unicode is meant to be a universal character code the same way as ASCII once was (though the character repertoire of ASCII was hopelessly insufficient for universal use), as opposite to using different codes in different systems and applications and for different languages.
Unicode as such defines only the “logical size” of characters: Each character has a code number in a specific range. These code numbers can be presented using different transfer encodings, and internally, in memory, Unicode characters are usually represented using one or two 16-bit quantities per character, depending on character range, sometimes using one 32-bit quantity per character.
I used the following query to retrieve the information of constraints in the SQL Server 2012, and works perfectly. I hope it would be useful for you.

,clmns.max_length AS [Column Max Length]
,clmns.precision AS [Column Precision]
,CASE WHEN clmns.is_nullable = 0 THEN 'NO' ELSE 'YES' END AS [Column Nullable]
,CASE WHEN clmns.is_identity = 0 THEN 'NO' ELSE 'YES' END AS [Column IS IDENTITY]

Just telling you about one other possibility: I like using friend definitions for that:
namespace Math
{
class Matrix
{
public:
[...]
friend std::ostream& operator<< (std::ostream& stream, const Matrix& matrix) {
[...]
}
};
}
The function will be automatically targeted into the surrounding namespace Math
(even though its definition appears within the scope of that class) but will not be visible unless you call operator<< with a Matrix object which will make argument dependent lookup find that operator definition. That can sometimes help with ambiguous calls, since it's invisible for argument types other than Matrix. When writing its definition, you can also refer directly to names defined in Matrix and to Matrix itself, without qualifying the name with some possibly long prefix and providing template parameters like Math::Matrix<TypeA, N>
.
Simply add style="line-height:0"
to each cell. This works in IE because it sets the line-height of both existant and non-existant text to about 19px and that forces the cells to expand vertically in most versions of IE. Regardless of whether or not you have text this needs to be done for IE to correctly display rows less than 20px high.
It makes a duplicate copy of the string passed in by running a malloc and strcpy of the string passed in. The malloc'ed buffer is returned to the caller, hence the need to run free on the return value.

Something simple like this can be done using subqueries in the select
clause:
select ((select sum(hours) from resource) +
(select sum(hours) from projects-time)
) as totalHours
For such a simple query as this, such a subselect is reasonable.
In some databases, you might have to add from dual
for the query to compile.
If you want to output each individually:
select (select sum(hours) from resource) as ResourceHours,
(select sum(hours) from projects-time) as ProjectHours
If you want both and the sum, a subquery is handy:
select ResourceHours, ProjectHours, (ResourceHours+ProjecctHours) as TotalHours
from (select (select sum(hours) from resource) as ResourceHours,
(select sum(hours) from projects-time) as ProjectHours
) t

Most of the time after the installation of Eclipse eclipse.ini is changed. If you change the jdk in eclipse.ini then eclipse will use this jdk by default.
Let's say you install a new version of Eclipse and you have forgotten to change the eclipse.ini related to the jdk. Then Eclipse finds a jdk for you. Let's say it is java 1.6 that was automatically discovered (you did nothing).
If you use maven (M2E) and you reference a 1.7 jdk then you will see the frustrating message. But normally it is not displayed because you configure the correct jdk in eclipse.ini.
That was my case. I made reference into the pom to a jdk that was not configured into Eclipse.
In the screenshot you can see that 1.7 is configured and seen by Eclipse. In this case, you should make reference into the pom to a jre that is compatible with 1.7! If not -> frustrating message!
Apply this trick.
First you need IP address of url you want to redirect to. Lets say you want to redirect to stackoverflow.com To find it, use the ping command in a Command Prompt. Type in:
ping stackoverflow.com
into the command prompt window and you’ll see stackoverflow's numerical IP address. Now use that IP into your host file
104.16.36.249 google.com
yay now google is serving stackoverflow :)
I found the there is a certificate expired issue with:
npm set registry https://registry.npmjs.org/
So I made it http, not https :-
npm set registry http://registry.npmjs.org/
And have no problems so far.
I was receiving the same error message, and my issue was that I was not in the correct directory when running the command make install
. When I changed to the directory that had my makefile it worked.
So possibly you aren't in the right directory.
you can use finishAffinity();
to close all the activity..
I really simplistic way I guess would be, for every exe that is running, you could create/open a file on disk in a known location (c:\temp) with a special name "yourapp.lock" and then just count how many of those there are.
A harder way, would be to open up some inter-process communication, or sockets, so with the process list you could interrogate each process to see if it was your application.
There's something really simple that you might be overlooking after trying to center the window using either setLocationRelativeTo(null)
or setLocation(x,y)
and it ends up being a little off center.
Make sure that you use either one of these methods after calling pack()
because the you'll end up using the dimensions of the window itself to calculate where to place it on screen. Until pack()
is called, the dimensions aren't what you'd think thus throwing off the calculations to center the window. Hope this helps.

You may want to save the blog link. I still reference it from time to time.
According to the docs for func (*Client) Do
:
"An error is returned if caused by client policy (such as CheckRedirect), or if there was an HTTP protocol error. A non-2xx response doesn't cause an error.
When err is nil, resp always contains a non-nil resp.Body."
Then looking at this code:
res, err := client.Do(req)
defer res.Body.Close()
if err != nil {
return nil, err
}
I'm guessing that err

. You're accessing the .Close()
method on res.Body
before you check for the err
.
The defer
only defers the function call. The field and method are accessed immediately.
So instead, try checking the error immediately.
res, err := client.Do(req)
if err != nil {
return nil, err
}
defer res.Body.Close()
No it's not. You may block right-clicks and simillar stuff but if someone wants to download it, he will do so, trust me ;)

That should do it.
Let us say you have a data frame you created and named "Data_output", you can simply export it to same directory by using the following syntax.
write.csv(Data_output, "output.csv", row.names = F, quote = F)
You don't need to locate the user if you only need their country. You can look their IP address up in any IP-to-location service (like maxmind, ipregistry or ip2location). This will be accurate most of the time.
If you really need to get their location, you can get their lat/lng with that method, then query Google's or Yahoo's reverse geocoding service.

You don't need to create a user-defined setting. The built-in setting "Preprocessor Macros" works just fine. alt text http://idisk.mac.com/cdespinosa/Public/Picture%204.png
If you have multiple targets or projects that use the same prefix file, use Preprocessor Macros Not Used In Precompiled Headers instead, so differences in your macro definition don't trigger an unnecessary extra set of precompiled headers.
My use case was to save range to variable and then select it later on
Dim targetRange As Range
Set targetRange = Sheets("Sheet").Range("Name")
Application.Goto targetRange
Set targetRangeQ = Nothing ' reset
@Query("SELECT distinct new com.model.referential.Asset(firefCode,firefDescription) FROM AssetClass ")

Use the CLIM function (equivalent to CAXIS function in MATLAB):
plt.pcolor(X, Y, v, cmap=cm)
plt.clim(-4,4) # identical to caxis([-4,4]) in MATLAB
plt.show()
Add this code inside your input tag
<?php if ($tag_1 == 'yes') echo "checked='checked'"; ?>
Assuming you want to throw away any changes you have, first check the output of git status
. For any file that says "unmerged" next to it, run git add <unmerged file>
. Then follow up with git reset --hard
. That will git rid of any local changes except for untracked files.

I solve this issue by switching from .NET 4.7.2 => .NET 4.5.2 and then switch back to 472. So in some cases this error occurs because package manager unable resolve dependences
You can try this:
au BufWinEnter * if &textwidth > 8
\ | let w:m1=matchadd('MatchParen', printf('\%%<%dv.\%%>%dv', &textwidth+1, &textwidth-8), -1)
\ | let w:m2=matchadd('ErrorMsg', printf('\%%>%dv.\+', &textwidth), -1)
\ | endif
That will set up two highlights in every buffer, one for characters in the 8 columns prior to whatever your &textwidth
is set to, and one for characters beyond that column. That way you have some extent of anticipation. Of course you can tweak it to use a different width if you want more or less anticipation (which you pay for in the form of loss of syntax highlighting in those columns).
If you want to convert an existing string to raw string, then we can reassign that like below
s1 = "welcome\tto\tPython"
raw_s1 = "%r"%s1
print(raw_s1)
Will print
welcome\tto\tPython
My quick-fix is to add the directory to the path:
import sys
sys.path.insert(0, '../components/')
You can't access form inputs via their name. Use document.getElements
methods instead.

usually means that jQuery DataTables cannot find the data in the response to the Ajax request.
By default jQuery DataTables expects the data to be in one of the formats shown below. Error occurs because data is returned in the format other than default.
Array of arrays

ECMAScript 2018 introduces named capturing groups into JavaScript regexes.
Example:
const auth = 'Bearer AUTHORIZATION_TOKEN'
const { groups: { token } } = /Bearer (?<token>[^ $]*)/.exec(auth)
console.log(token) // "Prints AUTHORIZATION_TOKEN"
If you need to support older browsers, you can do everything with normal (numbered) capturing groups that you can do with named capturing groups, you just need to keep track of the numbers - which may be cumbersome if the order of capturing group in your regex changes.
There are only two "structural" advantages of named capturing groups I can think of:
In some regex flavors (.NET and JGSoft, as far as I know), you can use the same name for different groups in your regex (see here for an example where this matters). But most regex flavors do not support this functionality anyway.
If you need to refer to numbered capturing groups in a situation where they are surrounded by digits, you can get a problem. Let's say you want to add a zero to a digit and therefore want to replace (\d)
with $10
. In JavaScript, this will work (as long as you have fewer than 10 capturing group in your regex), but Perl will think you're looking for backreference number 10
instead of number 1
, followed by a 0
. In Perl, you can use ${1}0
in this case.
Other than that, named capturing groups are just "syntactic sugar". It helps to use capturing groups only when you really need them and to use non-capturing groups (?:...)
in all other circumstances.
The bigger problem (in my opinion) with JavaScript is that it does not support verbose regexes which would make the creation of readable, complex regular expressions a lot easier.
Steve Levithan's XRegExp library solves these problems.

You are modifying the list book_shop.values()[i]
, which is not getting updated in the dictionary. Whenever you call the values()
method, it will give you the values available in dictionary, and here you are not modifying the data of the dictionary.
Do you checks that file is uploaded ok ? Maybe you exceeded max_post_size, or max_upload_filesize. When login using FileZilla you are copying files as you, when uploading by PHP wiritng this file is from user that runs apache (for exaplme www-data), try to put chmod 755 for images.
I tend to use the following pattern to check for the document to complete loading. The function returns a Promise (if you need to support IE, include the polyfill) that resolves once the document completes loading. It uses setInterval
underneath because a similar implementation with setTimeout
could result in a very deep stack.
function getDocReadyPromise()
{
function promiseDocReady(resolve)
{
function checkDocReady()
{
if (document.readyState === "complete")
{
clearInterval(intervalDocReady);
resolve();
}
}
var intervalDocReady = setInterval(checkDocReady, 10);
}
return new Promise(promiseDocReady);
}
Of course, if you don't have to support IE:
const getDocReadyPromise = () =>
{
const promiseDocReady = (resolve) =>
{
const checkDocReady = () =>
((document.readyState === "complete") && (clearInterval(intervalDocReady) || resolve()));
let intervalDocReady = setInterval(checkDocReady, 10);
}
return new Promise(promiseDocReady);
}
With that function, you can do the following:
getDocReadyPromise().then(whatIveBeenWaitingToDo);
You do not have to use final
, but the final
is making clear to everyone else - including the compiler - that this is a constant, and that's the good practice in it.
Why people doe that even if the constant will be used only in one place and only in the same class: Because in many cases it still makes sense. If you for example know it will be final during program run, but you intend to change the value later and recompile (easier to find), and also might use it more often later-on. It is also informing other programmers about the core values in the program flow at a prominent and combined place.
An aspect the other answers are missing out unfortunately, is that using the combination of public final
needs to be done very carefully, especially if other classes or packages will use your class (which can be assumed because it is public
).
Here's why:
final
, the compiler will inline this field during compile time into any compilation unit reading this field. So far, so good.public
, the compiler will also inline this value into any other compile unit. That means other classes using this field.What are the consequences?
Imagine you have this:
class Foo {
public static final String VERSION = "1.0";
}
class Bar {
public static void main(String[] args) {
System.out.println("I am using version " + Foo.VERSION);
}
}
After compiling and running Bar
, you'll get:
I am using version 1.0
Now, you improve Foo
and change the version to "1.1".
After recompiling Foo
, you run Bar
and get this wrong output:
I am using version 1.0
This happens, because VERSION
is declared final
, so the actual value of it was already in-lined in Bar
during the first compile run. As a consequence, to let the example of a public static final ...
field propagate properly after actually changing what was declared final
(you lied!;), you'd need to recompile every class using it.
I've seen this a couple of times and it is really hard to debug.
If by final
you mean a constant that might change in later versions of your program, a better solution would be this:
class Foo {
private static String version = "1.0";
public static final String getVersion() {
return version;
}
}
The performance penalty of this is negligible, since JIT code generator will inline it at run-time.
No need to use select
just use [
instead
data[,grepl("search_string", colnames(data))]
Let's try with iris
dataset
>iris[,grepl("Sepal", colnames(iris))]
Sepal.Length Sepal.Width
1 5.1 3.5
2 4.9 3.0
3 4.7 3.2
4 4.6 3.1
5 5.0 3.6
6 5.4 3.9
Try This:
$this->db->where('sell_date BETWEEN "'. date('Y-m-d', strtotime($start_date)). '" and "'. date('Y-m-d', strtotime($end_date)).'"');
Hope this will work

Recently when working on a web app for a client, I noticed that any click events added to a non-anchor element didn't work on the iPad or iPhone. All desktop and other mobile devices worked fine - but as the Apple products are the most popular mobile devices, it was important to get it fixed.
Turns out that any non-anchor element assigned a click handler in jQuery must either have an onClick attribute (can be empty like below):
onClick=""
OR
The element css needs to have the following declaration:
cursor:pointer
Strange, but that's what it took to get things working again!

I found another solution which you can convert it to whatever format you want and apply to all LocalDateTime datatype and you do not have to specify @JsonFormat above every LocalDateTime datatype. first add the dependency :
<dependency>
<groupId>com.fasterxml.jackson.datatype</groupId>
<artifactId>jackson-datatype-jsr310</artifactId>
</dependency>
Add the following bean :
@Configuration
public class Java8DateTimeConfiguration {
/**
* Customizing
* http://docs.spring.io/spring-boot/docs/current/reference/html/howto-spring-mvc.html
*
* Defining a @Bean of type Jackson2ObjectMapperBuilder will allow you to customize both default ObjectMapper and XmlMapper (used in MappingJackson2HttpMessageConverter and MappingJackson2XmlHttpMessageConverter respectively).
*/
@Bean
public Module jsonMapperJava8DateTimeModule() {
val bean = new SimpleModule();
bean.addDeserializer (ZonedDateTime.class, new JsonDeserializer<ZonedDateTime>() {
@Override
public ZonedDateTime deserialize(JsonParser jsonParser, DeserializationContext deserializationContext) throws IOException, JsonProcessingException {
return ZonedDateTime.parse(jsonParser.getValueAsString(), DateTimeFormatter.ISO_ZONED_DATE_TIME);
}
});
bean.addDeserializer(LocalDateTime.class, new JsonDeserializer<LocalDateTime>() {
@Override
public LocalDateTime deserialize(JsonParser jsonParser, DeserializationContext deserializationContext) throws IOException, JsonProcessingException {
return LocalDateTime.parse(jsonParser.getValueAsString(), DateTimeFormatter.ISO_LOCAL_DATE_TIME);
}
});
bean.addSerializer(ZonedDateTime.class, new JsonSerializer<ZonedDateTime>() {
@Override
public void serialize(
ZonedDateTime zonedDateTime, JsonGenerator jsonGenerator, SerializerProvider serializerProvider)
throws IOException {
jsonGenerator.writeString(DateTimeFormatter.ISO_ZONED_DATE_TIME.format(zonedDateTime));
}
});
bean.addSerializer(LocalDateTime.class, new JsonSerializer<LocalDateTime>() {
@Override
public void serialize(
LocalDateTime localDateTime, JsonGenerator jsonGenerator, SerializerProvider serializerProvider)
throws IOException {
jsonGenerator.writeString(DateTimeFormatter.ISO_LOCAL_DATE_TIME.format(localDateTime));
}
});
return bean;
}
}
in your config file add the following :
@Import(Java8DateTimeConfiguration.class)
This will serialize and de-serialize all properties LocalDateTime and ZonedDateTime as long as you are using objectMapper created by spring.
The format that you got for ZonedDateTime is : "2017-12-27T08:55:17.317+02:00[Asia/Jerusalem]" for LocalDateTime is : "2017-12-27T09:05:30.523"
I had the same error. Creating a new AVD with the appropriate API level solved my problem.
no, jquery always returns a jquery object regardless if a selector was matched or not. You need to use .length
if ( $('#someDiv').length ){
}
Inline styles cannot be used to target pseudo-classes or pseudo-elements. You need to use a stylesheet.
If you want to generate CSS dynamically, then the easiest way is to create a DOM element <style>
.
<style dangerouslySetInnerHTML={{
__html: [
'.my-special-div:after {',
' content: "Hello";',
' position: absolute',
'}'
].join('\n')
}}>
</style>
<div className='my-special-div'></div>

I've created a little Powershell function to emulate MSDOS pause
. This handles whether running Powershell ISE or non ISE. (ReadKey
does not work in powershell ISE). When running Powershell ISE, this function opens a Windows MessageBox

does not always come to the forefront. Anyway, here it goes:
Usage:
pause "Press any key to continue"

Set / change / reset the MySQL root password on Ubuntu Linux. Enter the following lines in your terminal.
sudo /etc/init.d/mysql stop
Start the mysqld
configuration: sudo mysqld --skip-grant-tables &
In some cases, you've to create the /var/run/mysqld
first:
sudo mkdir -v /var/run/mysqld && sudo chown mysql /var/run/mysqld
sudo service mysql start
mysql -u root mysql
Replace YOURNEWPASSWORD
with your new password:
UPDATE
mysql.user
SET
Password = PASSWORD('YOURNEWPASSWORD')
WHERE
User = 'root';
FLUSH PRIVILEGES;
exit;
Note: on some versions, if
password
column doesn't exist, you may want to try:
UPDATE user SET authentication_string=password('YOURNEWPASSWORD') WHERE user='root';
Note: This method is not regarded as the most secure way of resetting the password, however, it works.

Turning Hardware Acceleration OFF seems to be the setting that affects popups & dialogs.
Chrome was continually hiding Dialog Windows when I needed to respond Yes or No to things, also when I needed to Rename folders in my bookmarks panel. After weeks of doing this. I disabled all the Chrome helpers in Settings, Also In windows 10 I switched Window Snapping off. It has done something to put the popups and dialogs back in the Viewport.
When this bug is happening, I was able to shut a tab by first pressing Enter before clicking the tab close X button. The browser had an alert box, hidden which needed a response from the user.
Switching Hardware Accleration Off and back On, Killing the Chrome process and switching all the other Helpers Off and back has fixed it for me... It must be in chrome itself because Ive just gone into a Chrome window in the Mac and it has now stopped the problem, without any intervention. Im guessing flicking the chrome settings on/off/on has caused it to reposition the dialogs. I cant get the browser to repeat the fault now...
Just trying to make it as easy as possible see code below:
- (void)viewDidLoad
{
[self appWillEnterForeground]; //register For Application Will enterForeground
}
- (id)appWillEnterForeground{ //Application will enter foreground.
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(allFunctions)
name:UIApplicationWillEnterForegroundNotification
object:nil];
return self;
}
-(void) allFunctions{ //call any functions that need to be run when application will enter foreground
NSLog(@"calling all functions...application just came back from foreground");
}
I had the similar issue. Probably check if you are using proxy.
If yes, set up the proxy before doing download:
nltk.set_proxy('http://proxy.example.com:3128', ('USERNAME', 'PASSWORD'))
In case you need to convert the returned date of a select statement to a specific format you may use the following:
select to_char(DATE (*date_you_want_to_select*)::date, 'DD/MM/YYYY') as "Formated Date"
To prevent IE 8 CTRL and SHIFT click text selection on individual element
var obj = document.createElement("DIV");
obj.onselectstart = function(){

To prevent text selection on document
window.onload = function(){
document.onselectstart = function(){
return false;
}
}
If you not want include other function like 'ReDimPreserve' could use temporal matrix for resizing. On based to your code:
Dim n As Integer, m As Integer, i as Long, j as Long
Dim arrTemporal() as Variant
n = 1
m = 0
Dim arrCity() As String
ReDim arrCity(n, m)
n = n + 1
m = m + 1
'VBA automatically adapts the size of the receiving matrix.
arrTemporal = arrCity
ReDim arrCity(n, m)
'Loop for assign values to arrCity
For i = 1 To UBound(arrTemporal , 1)
For j = 1 To UBound(arrTemporal , 2)
arrCity(i, j) = arrTemporal (i, j)
Next
Next
If you not declare of type VBA assume that is Variant.
Dim n as Integer, m As Integer
I faced the same issue, mine is even more complicated.
Admin will upload audio and pdf files into storage:
audios/season1, season2.../class1, class 2/.mp3 files
books/.pdf files
Android app needs to get the list of sub folders and files.
The solution is catching the upload event on storage and create the same structure on firestore using cloud function.
Step 1: Create manually 'storage' collection and 'audios/books' doc on firestore
Step 2: Setup cloud function
Might take around 15 mins: https://www.youtube.com/watch?v=DYfP-UIKxH0&list=PLl-K7zZEsYLkPZHe41m4jfAxUi0JjLgSM&index=1
Step 3: Catch upload event using cloud function
import * as functions from 'firebase-functions';
import * as admin from 'firebase-admin';
admin.initializeApp(functions.config().firebase);
const path = require('path');
export const onFileUpload = functions.storage.object().onFinalize(async (object) => {
let filePath = object.name; // File path in the bucket.
const contentType = object.contentType; // File content type.
const metageneration = object.metageneration; // Number of times metadata has been generated. New objects have a value of 1.
if (metageneration !== "1") return;
// Get the file name.
const fileName = path.basename(filePath);
filePath = filePath.substring(0, filePath.length - 1);
console.log('contentType ' + contentType);
console.log('fileName ' + fileName);
console.log('filePath ' + filePath);
console.log('path.dirname(filePath) ' + path.dirname(filePath));
filePath = path.dirname(filePath);
const pathArray = filePath.split("/");
let ref = '';
for (const item of pathArray) {
if (ref.length === 0) {
ref = item;
}
else {
ref = ref.concat('/sub/').concat(item);
}
}
ref = 'storage/'.concat(ref).concat('/sub')
admin.firestore().collection(ref).doc(fileName).create({})
.then(result => {console.log('onFileUpload:updated')})
.catch(error => {
console.log(error);
});
});
Step 4: Retrieve list of folders/files on Android app using firestore
private static final String STORAGE_DOC = "storage/";
public static void getMediaCollection(String path, OnCompleteListener onCompleteListener) {
String[] pathArray = path.split("/");
String doc = null;
for (String item : pathArray) {
if (TextUtils.isEmpty(doc)) doc = STORAGE_DOC.concat(item);
else doc = doc.concat("/sub/").concat(item);
}
doc = doc.concat("/sub");
getFirestore().collection(doc).get().addOnCompleteListener(onCompleteListener);
}
Step 5: Get download url
public static void downloadMediaFile(String path, OnCompleteListener<Uri> onCompleteListener) {
getStorage().getReference().child(path).getDownloadUrl().addOnCompleteListener(onCompleteListener);
}
Note
We have to put "sub" collection to each item since firestore doesn't support to retrieve the list of collection.
It took me 3 days to find out the solution, hopefully will take you 3 hours at most.
Cheers.
Actually AllocConsole with SetStdHandle in a GUI application might be a safer approach. The problem with the "console hijacking" already mentioned, is that the console might not be a foreground window at all, (esp. considering the influx of new window managers in Vista/Windows 7) among other things.
I had this problem when I did a SharePoint 2010 to 2013 migration. I suspected that because the database server is on the other side of a firewall which does not route IP6 that it was trying then to use IP6 and failing when connecting to the database.
I think the issue is now solved. The errors seem to have stopped. What I did was I simply disabled IP6 (by unchecking it) for the network adapter on the SharePoint Servers.
I found out why this happening.
After looking at my settings on my wamp, i did not check http headers, since activated this, it now works.
Thank you everyone for trying to solve this. :)
The static keyword, when applied to a class, tells the compiler to create a single instance of that class. It is not then possible to 'new' one or more instance of the class. All methods in a static class must themselves be declared static.
It is possible, And often desirable, to have static methods of a non-static class. For example a factory method when creates an instance of another class is often declared static as this means that a particular instance of the class containing the factor method is not required.
For a good explanation of how, when and where see MSDN
I was having some trouble using an Indeterminate Progress Dialog with the solution here, after some work and trial and error I got it to work.
First, create the animation you want to use for the Progress Dialog. In my case I used 5 images.
../res/anim/progress_dialog_icon_drawable_animation.xml:
<animation-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@drawable/icon_progress_dialog_drawable_1" android:duration="150" />
<item android:drawable="@drawable/icon_progress_dialog_drawable_2" android:duration="150" />
<item android:drawable="@drawable/icon_progress_dialog_drawable_3" android:duration="150" />
<item android:drawable="@drawable/icon_progress_dialog_drawable_4" android:duration="150" />
<item android:drawable="@drawable/icon_progress_dialog_drawable_5" android:duration="150" />
</animation-list>
Where you want to show a ProgressDialog:
dialog = new ProgressDialog(Context.this);
dialog.setIndeterminate(true);
dialog.setIndeterminateDrawable(getResources().getDrawable(R.anim.progress_dialog_icon_drawable_animation));
dialog.setMessage("Some Text");
dialog.show();
This solution is really simple and worked for me, you could extend ProgressDialog and make it override the drawable internally, however, this was really too complicated for what I needed so I did not do it.
You need INDIRECT
function:
=INDIRECT("'"&A5&"'!G7")
List<String> items = new ArrayList<>();
items.add("A");
items.add("B");
items.add("C");
items.add("D");
items.add("E");
//lambda
//Output : A,B,C,D,E
items.forEach(item->System.out.println(item));
//Output : C
items.forEach(item->{
System.out.println(item);
System.out.println(item.toLowerCase());
}
});
My solution.
Before doing anything check:
if (!$this->entityManager->isOpen()) {
$this->entityManager = $this->entityManager->create(
$this->entityManager->getConnection(),
$this->entityManager->getConfiguration()
);
}
All entities will be saved. But it is handy for particular class or some cases. If you have some services with injected entitymanager, it still be closed.
If the data to be encoded contains "exotic" characters, I think you have to encode in "UTF-8"
encoded = base64.b64encode (bytes('data to be encoded', "utf-8"))
Perhaps you'd consider using android:shadowColor, android:shadowDx
, android:shadowDy
, android:shadowRadius
; alternatively setShadowLayer() ?
OOP should be the approach and frame
should be a class variable instead of instance variable.
from Tkinter import *
class App:
def __init__(self, master):
frame = Frame(master)
frame.pack()
self.button = Button(frame,
text="QUIT", fg="red",
command=frame.quit)
self.button.pack(side=LEFT)
self.slogan = Button(frame,
text="Hello",
command=self.write_slogan)
self.slogan.pack(side=LEFT)
def write_slogan(self):
print "Tkinter is easy to use!"
root = Tk()
app = App(root)
root.mainloop()
FileNotFound
is just an unfortunate exception used to indicate that the web server returned a 404.
Not an official name per se, but I've heard vertical ellipsis referred to as "snowman" in SAS community.
