No.
A developer is responsible for keeping track of time-zone information associated with a DateTime value via some external mechanism.
A quote from an excellent article here. A must read for every .Net developer.
So my advice is to write a little wrapper class that suits your needs.
For UUID4 I make it that there are approximately as many IDs as there are grains of sand in a cube-shaped box with sides 360,000km long. That's a box with sides ~2 1/2 times longer than Jupiter's diameter.
Working so someone can tell me if I've messed up units:
To initialize long you need to append "L" to the end.
It can be either uppercase or lowercase.
All the numeric values are by default int
. Even when you do any operation of byte
with any integer, byte
is first promoted to int
and then any operations are performed.
Try this
byte a = 1; // declare a byte
a = a*2; // you will get error here
You get error because 2
is by default int
.
Hence you are trying to multiply byte
with int
.
Hence result gets typecasted to int
which can't be assigned back to byte
.
you must write it in SQL not it C/PHP style
IF( action = 2 AND state = 0, 1, 0 ) AS state
for use in query
IF ( action = 2 AND state = 0 ) THEN SET state = 1
for use in stored procedures or functions
You can use easy & simple EasyFonts third party library to set variety of custom font to your TextView
. By using this library you should not have to worry about downloading and adding fonts into the assets/fonts folder. Also about Typeface object creation. You will be free from creating asset folder too.
Simply:
TextView myTextView = (TextView)findViewById(R.id.myTextView);
myTextView.setTypeface(EasyFonts.robotoThin(this));
There are many type of fonts provided by this library.
Try this, which I think makes it clear. the underlying array is changed but our slice is not, print
just prints len()
chars, by another slice to the cap()
, you can see the changed array:
func main() {
for i := 0; i < 7; i++ {
a[i] = i
}
Test(a)
fmt.Println(a) // prints [0..6]
fmt.Println(a[:cap(a)] // prints [0..6,100]
}
By default Jsonresult "Deny get"
Suppose if we have method like below
[HttpPost]
public JsonResult amc(){}
By default it "Deny Get".
In the below method
public JsonResult amc(){}
When you need to allowget or use get ,we have to use JsonRequestBehavior.AllowGet.
public JsonResult amc()
{
return Json(new Modle.JsonResponseData { Status = flag, Message = msg, Html = html }, JsonRequestBehavior.AllowGet);
}

Successful! hope this helps.
In my case DialogFragment
occupied full activity size like a Fragment
. The DialogFragment
was based on XML-layout, not AlertDialog
. My mistake was adding the dialog fragment to FragmentManager
as a usual fragment:
fragmentManager?.beginTransaction()?.run {
replace(R.id.container, MyDialogFragment.newInstance(), MyDialogFragment.TAG)
addToBackStack(MyDialogFragment.TAG)
}?.commitAllowingStateLoss()
Instead I need to show
the dialog fragment:
val dialogFragment = MyDialogFragment.newInstance()
fragmentManager?.let { dialogFragment.show(it, MyDialogFragment.TAG) }
After some editing (I have ViewPager2
in the layout) the dialog fragment became too narrow:
I used the solution of N1hk:
override fun onActivityCreated(savedInstanceState: Bundle?) {
super.onActivityCreated(savedInstanceState)
dialog?.window?.attributes?.width = ViewGroup.LayoutParams.MATCH_PARENT
dialog?.window?.attributes?.height = ViewGroup.LayoutParams.MATCH_PARENT
}
Now it has defined width and height, not full activity size.
I want to say about onCreateView
and onCreateDialog
. If you have a dialog fragment based on layout, you can use any of these 2 methods.
If you use onCreateView
, then you should use onActivityCreated
to set width.
If you use onCreateDialog
instead of onCreateView
, you can set parameters there. onActivityCreated
won't be needed.
override fun onCreateDialog(savedInstanceState: Bundle?): Dialog { super.onCreateDialog(savedInstanceState)
val view = activity?.layoutInflater?.inflate(R.layout.your_layout, null)
val dialogBuilder = MaterialAlertDialogBuilder(context!!).apply { // Or AlertDialog.Builder(context!!).apply
setView(view)
// setCancelable(false)
}
view.text_view.text = "Some text"
val dialog = dialogBuilder.create()
// You can access dialog.window here, if needed.
return dialog
}
You can Simply use
finish();
startActivity(getIntent());
to refresh an Activity
from within itself.
Been a while since I was in ASP land, but iirc there's a couple of ways:
try catch finally
can be reasonably simulated in VBS (good article here here) and there's an event called class_terminate
you can watch and catch exceptions globally in. Then there's the possibility of changing your scripting language...
You will not be able to find out the password he chose. However, you may create a new user or set a new password to the existing user.
Usually, you can login as the postgres user:
Open a Terminal and do sudo su postgres
.
Now, after entering your admin password, you are able to launch psql
and do
CREATE USER yourname WITH SUPERUSER PASSWORD 'yourpassword';
This creates a new admin user. If you want to list the existing users, you could also do
\du
to list all users and then
ALTER USER yourusername WITH PASSWORD 'yournewpass';
I suspect you haven't set up last_name
properly in the caller.
With the statement Worksheets(data_sheet).Range("C2").Value = ProcessString(last_name)
this will only work if last_name
is a string, i.e.
Dim last_name as String
appears in the caller somewhere.
The reason for this is that VBA passes in variables by reference by default which means that the data types have to match exactly between caller and callee.
1) Force ByVal -- Change your function to pass variable ByVal: Public Function ProcessString(ByVal input_string As String) As String
, or
2) Dim varname -- put Dim last_name As String
in the caller before you use it.
(1) works because for ByVal
, a copy of input_string is taken when passing to the function which will coerce it into the correct data type. It also leads to better program stability since the function cannot modify the variable in the caller.
Breadth first is a queue, depth first is a stack.
For breadth first, add all children to the queue, then pull the head and do a breadth first search on it, using the same queue.
For depth first, add all children to the stack, then pop and do a depth first on that node, using the same stack.
A stored procedure is a set of precompiled SQL statements that are used to perform a special task.
Example: If I have an Employee
table
Employee ID Name Age Mobile
---------------------------------------
001 Sidheswar 25 9938885469
002 Pritish 32 9178542436
First I am retrieving the Employee
table:
Create Procedure Employee details
As
Begin
Select * from Employee
End
To run the procedure on SQL Server:
Execute Employee details
--- (Employee details is a user defined name, give a name as you want)
Then second, I am inserting the value into the Employee Table
Create Procedure employee_insert
(@EmployeeID int, @Name Varchar(30), @Age int, @Mobile int)
As
Begin
Insert Into Employee
Values (@EmployeeID, @Name, @Age, @Mobile)
End
To run the parametrized procedure on SQL Server:
Execute employee_insert 003,’xyz’,27,1234567890
--(Parameter size must be same as declared column size)
Example: @Name Varchar(30)
In the Employee
table the Name
column's size must be varchar(30)
.
in ubuntu or windows
Remove the ; from ;extension=pdo_mysql or extension=php_pdo_mysql.dll and add extension=pdo_mysql.so
restart xampp or wampp
install sudo apt-get install php-mysql
and
php artisan migrate
Agree with redsquare however it is worth mentioning that if you have a two word property like text-align
you would do this:
$("#message").css({ width: '30px', height: '10px', 'text-align': 'center'});
Simplicity is a virtue. Use this naturally readable array:
char alphabet[] = {'a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j', 'k', 'l', 'm', 'n', 'o', 'p', 'q', 'r', 's', 't', 'u', 'v', 'w', 'x', 'y', 'z'};
The sql array type is not neccessary. Not if the element type is a primitive one. (Varchar, number, date,...)
Very basic sample:
declare
type TPidmList is table of sgbstdn.sgbstdn_pidm%type;
pidms TPidmList;
begin
select distinct sgbstdn_pidm
bulk collect into pidms
from sgbstdn
where sgbstdn_majr_code_1 = 'HS04'
and sgbstdn_program_1 = 'HSCOMPH';
-- do something with pidms
open :someCursor for
select value(t) pidm
from table(pidms) t;
end;
When you want to reuse it, then it might be interesting to know how that would look like. If you issue several commands than those could be grouped in a package. The private package variable trick from above has its downsides. When you add variables to a package, you give it state and now it doesn't act as a stateless bunch of functions but as some weird sort of singleton object instance instead.
e.g. When you recompile the body, it will raise exceptions in sessions that already used it before. (because the variable values got invalided)
However, you could declare the type in a package (or globally in sql), and use it as a paramter in methods that should use it.
create package Abc as
type TPidmList is table of sgbstdn.sgbstdn_pidm%type;
function CreateList(majorCode in Varchar,
program in Varchar) return TPidmList;
function Test1(list in TPidmList) return PLS_Integer;
-- "in" to make it immutable so that PL/SQL can pass a pointer instead of a copy
procedure Test2(list in TPidmList);
end;
create package body Abc as
function CreateList(majorCode in Varchar,
program in Varchar) return TPidmList is
result TPidmList;
begin
select distinct sgbstdn_pidm
bulk collect into result
from sgbstdn
where sgbstdn_majr_code_1 = majorCode
and sgbstdn_program_1 = program;
return result;
end;
function Test1(list in TPidmList) return PLS_Integer is
result PLS_Integer := 0;
begin
if list is null or list.Count = 0 then
return result;
end if;
for i in list.First .. list.Last loop
if ... then
result := result + list(i);
end if;
end loop;
end;
procedure Test2(list in TPidmList) as
begin
...
end;
return result;
end;
How to call it:
declare
pidms constant Abc.TPidmList := Abc.CreateList('HS04', 'HSCOMPH');
xyz PLS_Integer;
begin
Abc.Test2(pidms);
xyz := Abc.Test1(pidms);
...
open :someCursor for
select value(t) as Pidm,
xyz as SomeValue
from table(pidms) t;
end;
So from the error above. All you have to do to fix this issue is to revert your code. (git revert HEAD
) then git pull
and then redo your changes, then git pull
again and was able to commit or merge with no errors.
If someone asks about string reverse, the intension could be to find out whether you know any bitwise operation like XOR. In C# you have Array.Reverse function, however, you can do using simple XOR operation in few lines of code(minimal)
public static string MyReverse(string s)
{
char[] charArray = s.ToCharArray();
int bgn = -1;
int end = s.Length;
while(++bgn < --end)
{
charArray[bgn] ^= charArray[end];
charArray[end] ^= charArray[bgn];
charArray[bgn] ^= charArray[end];
}
return new string(charArray);
}
Git tags are just pointers to the commit. So you use them the same way as you do HEAD, branch names or commit sha hashes. You can use tags with any git command that accepts commit/revision arguments. You can try it with git rev-parse tagname
to display the commit it points to.
In your case you have at least these two alternatives:
Reset the current branch to specific tag:
git reset --hard tagname
Generate revert commit on top to get you to the state of the tag:
git revert tag
This might introduce some conflicts if you have merge commits though.
In my case, there are several interpreters, but I have to manually add them.
To the right of where you see "No Interpreters", there is a gear icon. Click the gear icon -> Click "Add...", then you can add the ones you need.
you can't increase the heap size dynamically.
you can request to use more by using android:largeHeap="true"
in the manifest.
also, you can use native memory (NDK & JNI)
, so you actually bypass the heap size limitation.
here are some posts i've made about it:
and here's a library i've made for it:
All Answers are right, but i still want to give some other alternatives that may work.
If you are looking for the assigned width (ignoring padding, margin and so on) you could use.
getComputedStyle(element).width; //returns value in px like "727.7px"
getComputedStyle allows you to access all styles of that elements. For example: padding, paddingLeft, margin, border-top-left-radius and so on.
If you like to remove last 5 characters, you can use:
path.substring(0,path.length() - 5)
( could contain off by one error ;) )
If you like to remove some variable string:
path.substring(0,path.lastIndexOf('yoursubstringtoremove));
(could also contain off by one error ;) )
Why not make use of a tooltip?
private void ShowToolTip(object sender, string message)
{
new ToolTip().Show(message, this, Cursor.Position.X - this.Location.X, Cursor.Position.Y - this.Location.Y, 1000);
}
The code above will show message for 1000 milliseconds (1 second) where you clicked.
To call it, you can use the following in your button click event:
ShowToolTip("Hello World");
If you're using the public API, the best way to do it is using if
statements.
If the video is public or unlisted, you set the thumbnail using the URL method. If the video is private you use the API to get the thumbnail.
<?php
if($video_status == 'unlisted'){
$video_thumbnail = 'http://img.youtube.com/vi/'.$video_url.'/mqdefault.jpg';
$video_status = '<i class="fa fa-lock"></i> Unlisted';
}
elseif($video_status == 'public'){
$video_thumbnail = 'http://img.youtube.com/vi/'.$video_url.'/mqdefault.jpg';
$video_status = '<i class="fa fa-eye"></i> Public';
}
elseif($video_status == 'private'){
$video_thumbnail = $playlistItem['snippet']['thumbnails']['maxres']['url'];
$video_status = '<i class="fa fa-lock"></i> Private';
}
return results == null ? 0 : (results[1] || 0);
I know this may seem obvious but I also had to use a single quote around the u/n and p/w before it worked
mongo admin -u 'user' -p 'password'
What you really want to do is to remove any string that starts with either http://
or https://
plus any combination of non white space characters. Here is how I would solve it. My solution is very similar to that of @tolgayilmaz
#Define the text from which you want to replace the url with "".
text ='''The link to this post is https://stackoverflow.com/questions/11331982/how-to-remove-any-url-within-a-string-in-python'''
import re
#Either use:
re.sub('http://\S+|https://\S+', '', text)
#OR
re.sub('http[s]?://\S+', '', text)
And the result of running either code above is
>>> 'The link to this post is '
I prefer the second one because it is more readable.
I found a combination of the first two answers gave me what I needed. I used the CurrentCellDirtyStateChanged event and inspected the EditedFormattedValue.
private void dgv_CurrentCellDirtyStateChanged(object sender, EventArgs e)
{
DataGridView dgv = (DataGridView)sender;
DataGridViewCell cell = dgv.CurrentCell;
if (cell.RowIndex >= 0 && cell.ColumnIndex == 3) // My checkbox column
{
// If checkbox checked, copy value from col 1 to col 2
if (dgv.Rows[cell.RowIndex].Cells[cell.ColumnIndex].EditedFormattedValue != null && dgv.Rows[cell.RowIndex].Cells[cell.ColumnIndex].EditedFormattedValue.Equals(true))
{
dgv.Rows[cell.RowIndex].Cells[1].Value = dgv.Rows[cell.RowIndex].Cells[2].Value;
}
}
}
Add a reference to it in your project and a using clause at the top of the CS file where you want to use it.
Adding a reference:
Adding a using clause:
Add "using [namespace];" to the CS file where you want to reference your library. So, if the library you want to reference has a namespace called MyLibrary, add the following to the CS file:
using MyLibrary;
The shortest expression is
curl 'http://…' | jq length
UPDATE: for rxjs > v5.5
As mentioned in some of the comments and other answers, by default the HttpClient deserializes the content of a response into an object. Some of its methods allow passing a generic type argument in order to duck-type the result. Thats why there is no json()
method anymore.
import {throwError} from 'rxjs';
import {catchError, map} from 'rxjs/operators';
export interface Order {
// Properties
}
interface ResponseOrders {
results: Order[];
}
@Injectable()
export class FooService {
ctor(private http: HttpClient){}
fetch(startIndex: number, limit: number): Observable<Order[]> {
let params = new HttpParams();
params = params.set('startIndex',startIndex.toString()).set('limit',limit.toString());
// base URL should not have ? in it at the en
return this.http.get<ResponseOrders >(this.baseUrl,{
params
}).pipe(
map(res => res.results || []),
catchError(error => _throwError(error.message || error))
);
}
Notice that you could easily transform the returned Observable
to a Promise
by simply invoking toPromise()
.
ORIGINAL ANSWER:
In your case, you can
Assumming that your backend returns something like:
{results: [{},{}]}
in JSON format, where every {} is a serialized object, you would need the following:
// Somewhere in your src folder
export interface Order {
// Properties
}
import { HttpClient, HttpParams } from '@angular/common/http';
import { Observable } from 'rxjs/Observable';
import 'rxjs/add/operator/catch';
import 'rxjs/add/operator/map';
import { Order } from 'somewhere_in_src';
@Injectable()
export class FooService {
ctor(private http: HttpClient){}
fetch(startIndex: number, limit: number): Observable<Order[]> {
let params = new HttpParams();
params = params.set('startIndex',startIndex.toString()).set('limit',limit.toString());
// base URL should not have ? in it at the en
return this.http.get(this.baseUrl,{
params
})
.map(res => res.results as Order[] || []);
// in case that the property results in the res POJO doesnt exist (res.results returns null) then return empty array ([])
}
}
I removed the catch section, as this could be archived through a HTTP interceptor. Check the docs. As example:
https://gist.github.com/jotatoledo/765c7f6d8a755613cafca97e83313b90
And to consume you just need to call it like:
// In some component for example
this.fooService.fetch(...).subscribe(data => ...); // data is Order[]
Use os.path.join to combine the path to the Documents
directory with the completeName
(filename?) supplied by the user.
import os
with open(os.path.join('/path/to/Documents',completeName), "w") as file1:
toFile = raw_input("Write what you want into the field")
file1.write(toFile)
If you want the Documents
directory to be relative to the user's home directory, you could use something like:
os.path.join(os.path.expanduser('~'),'Documents',completeName)
Others have proposed using os.path.abspath
. Note that os.path.abspath
does not resolve '~'
to the user's home directory:
In [10]: cd /tmp
/tmp
In [11]: os.path.abspath("~")
Out[11]: '/tmp/~'
Element needs to be a variant, so you can't declare it as a string. Your function should accept a variant if it is a string though as long as you pass it ByVal.
Public Sub example()
Dim sArray(4) As string
Dim element As variant
For Each element In sArray
do_something (element)
Next element
End Sub
Sub do_something(ByVal e As String)
End Sub
The other option is to convert the variant to a string before passing it.
do_something CStr(element)
You can use the property object-fit
.cover {
object-fit: cover;
width: 150px;
height: 100px;
}
Like suggested here
A full explanation of this property by Chris Mills in Dev.Opera
And an even better one in CSS-Tricks
It's supported in
I just checked that vivaldi and chromium support it as well (no surprise here)
It's currently not supported on IE, but... who cares ? Also, iOS supports object-fit, but not object-position, but it will soon.
Section 6.16 Frame target names in the HTML 4.01 spec defines the meanings, but it is partly outdated. It refers to “windows”, whereas HTML5 drafts more realistically speak about “browsing contexts”, since modern browsers often use tabs instead of windows in this context.
Briefly, _self
is the default (current browsing context, i.e. current window or tab), so it is useful only to override a <base target=...>
setting. The value _parent
refers to the frameset that is the parent of the current frame, whereas _top
“breaks out of all frames” and opens the linked document in the entire browser window.
I think the V$SQLAREA table contains what you're looking for (see columns SQL_TEXT and SQL_FULLTEXT).
If you are using CentOS linux system the Maven local repositary will be:

Suggest the following simplification: capture return value from Workbooks.Add
instead of subscripting Windows()
afterward, as follows:
Set wkb = Workbooks.Add
wkb.SaveAs ...
wkb.Activate ' instead of Windows(expression).Activate
General Philosophy Advice:
Avoid use Excel's built-ins: ActiveWorkbook, ActiveSheet, and Selection: capture return values, and, favor qualified expressions instead.
Use the built-ins only once and only in outermost macros(subs) and capture at macro start, e.g.
Set wkb = ActiveWorkbook
Set wks = ActiveSheet
Set sel = Selection
During and within macros do not rely on these built-in names, instead capture return values, e.g.
Set wkb = Workbooks.Add 'instead of Workbooks.Add without return value capture
wkb.Activate 'instead of Activeworkbook.Activate
Also, try to use qualified expressions, e.g.
wkb.Sheets("Sheet3").Name = "foo" ' instead of Sheets("Sheet3").Name = "foo"
or
Set newWks = wkb.Sheets.Add
newWks.Name = "bar" 'instead of ActiveSheet.Name = "bar"
Use qualified expressions, e.g.
newWks.Name = "bar" 'instead of `xyz.Select` followed by Selection.Name = "bar"
These methods will work better in general, give less confusing results, will be more robust when refactoring (e.g. moving lines of code around within and between methods) and, will work better across versions of Excel. Selection, for example, changes differently during macro execution from one version of Excel to another.
Also please note that you'll likely find that you don't need to .Activate
nearly as much when using more qualified expressions. (This can mean the for the user the screen will flicker less.) Thus the whole line Windows(expression).Activate
could simply be eliminated instead of even being replaced by wkb.Activate
.
(Also note: I think the .Select statements you show are not contributing and can be omitted.)
(I think that Excel's macro recorder is responsible for promoting this more fragile style of programming using ActiveSheet, ActiveWorkbook, Selection, and Select so much; this style leaves a lot of room for improvement.)
here is how to validate the input to only accept numbers this will accept numbers like 123123123.41212313
<input type="text"
onkeypress="if ( isNaN(this.value + String.fromCharCode(event.keyCode) )) return false;"
/>
and this will not accept entering the dot (.), so it will only accept integers
<input type="text"
onkeypress="if ( isNaN( String.fromCharCode(event.keyCode) )) return false;"
/>
this way you will not permit the user to input anything but numbers
You shouldn't be using string.h
if you're coding in C++. Strings in C++ are of the std::string
variety which is a lot easier to use than then old C-style "strings". Use:
#include <string>
to get the correct information and something std::string s
to declare one. The many wonderful ways you can use std::string
can be seen here.
If you have a look at the large number of questions on Stack Overflow regarding the use of C strings, you'll see why you should avoid them where possible :-)
Just ps -o etime= -p "<your_process_pid>"
Use DateFormat. For example,
SimpleDateFormat isoFormat = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss");
isoFormat.setTimeZone(TimeZone.getTimeZone("UTC"));
Date date = isoFormat.parse("2010-05-23T09:01:02");
Efficient way to iterate your ArrayList

int size = list.size();
for(int j = 0; j < size; j++) {
System.out.println(list.get(i));
}
I have tried everything but could not make it work. Finally I have used pyenv
and it worked directly like a charm.
So having homebrew
installed, juste do:
brew install pyenv
pyenv install 3.6.5
to manage virtualenvs:
brew install pyenv-virtualenv
pyenv virtualenv 3.6.5 env_name
See pyenv and pyenv-virtualenv for more info.
I have found using the pyenv-installer easier than homebrew to install pyenv and pyenv-virtualenv direclty:
curl https://pyenv.run | bash
To manage python version, either globally:
pyenv global 3.6.5
or locally in a given directory:
pyenv local 3.6.5

Maybe you can use the [Integer] data annotation (If you use the DataAnnotationsExtensions http://dataannotationsextensions.org/) . However, this wil only check if the value is an integer, nót if it is filled in (So you may also need the [Required] attribute).
If you enable Unobtrusive Validation it will validate it clientside, but you should also use Modelstate.Valid in your POST action to decline it in case people have Javascript disabled.

This probably isn't exactly the answer you're looking for, but having struggled with this myself and having issues with suggested answers, I decided to make it uncontrolled instead.
When editable
prop is false
, I use text
prop as is, but when it is true
, I switch to editing mode in which text
has no effect (but at least browser doesn't freak out). During this time onChange
are fired by the control. Finally, when I change editable
back to false
, it fills HTML with whatever was passed in text
:
/** @jsx React.DOM */
'use strict';
var React = require('react'),
escapeTextForBrowser = require('react/lib/escapeTextForBrowser'),
{ PropTypes } = React;
var UncontrolledContentEditable = React.createClass({
propTypes: {
component: PropTypes.func,
onChange: PropTypes.func.isRequired,
text: PropTypes.string,
placeholder: PropTypes.string,
editable: PropTypes.bool
},
getDefaultProps() {
return {
component: React.DOM.div,
editable: false
};
},
getInitialState() {
return {
initialText: this.props.text
};
},
componentWillReceiveProps(nextProps) {
if (nextProps.editable && !this.props.editable) {
this.setState({
initialText: nextProps.text
});
}
},
componentWillUpdate(nextProps) {
if (!nextProps.editable && this.props.editable) {
this.getDOMNode().innerHTML = escapeTextForBrowser(this.state.initialText);
}
},
render() {
var html = escapeTextForBrowser(this.props.editable ?
this.state.initialText :
this.props.text
);
return (
<this.props.component onInput={this.handleChange}
onBlur={this.handleChange}
contentEditable={this.props.editable}
dangerouslySetInnerHTML={{__html: html}} />
);
},
handleChange(e) {
if (!e.target.textContent.trim().length) {
e.target.innerHTML = '';
}
this.props.onChange(e);
}
});
module.exports = UncontrolledContentEditable;
The extensions methods also provide a ToDictionary extension. It is fairly simple to use, the general usage is passing a lambda selector for the key and getting the object as the value, but you can pass a lambda selector for both key and value.
class SomeObject
{
public int ID { get; set; }
public string Name { get; set; }
}
SomeObject[] objects = new SomeObject[]
{
new SomeObject { ID = 1, Name = "Hello" },
new SomeObject { ID = 2, Name = "World" }
};
Dictionary<int, string> objectDictionary = objects.ToDictionary(o => o.ID, o => o.Name);
Then objectDictionary[1]
Would contain the value "Hello"
You can use list slicing to archive your goal:
n = 5
mylist = [1,2,3,4,5,6,7,8,9]
newlist = mylist[n:]
print newlist
Outputs:
[6, 7, 8, 9]
Or del
if you only want to use one list:
n = 5
mylist = [1,2,3,4,5,6,7,8,9]
del mylist[:n]
print mylist
Outputs:
[6, 7, 8, 9]
In my case I showed DialogFragment
in Activity
. In this dialog fragment I wrote as in DialogFragment remove black border:
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setStyle(STYLE_NO_FRAME, 0)
}
override fun onCreateDialog(savedInstanceState: Bundle?): Dialog {
super.onCreateDialog(savedInstanceState)
val dialog = Dialog(context!!, R.style.ErrorDialogTheme)
val inflater = LayoutInflater.from(context)
val view = inflater.inflate(R.layout.fragment_error_dialog, null, false)
dialog.setTitle(null)
dialog.setCancelable(true)
dialog.setContentView(view)
return dialog
}
Either remove setStyle(STYLE_NO_FRAME, 0)
in onCreate()
or chande/remove onCreateDialog
. Because dialog settings have changed after the dialog has been created.

If you are having a small script that you need to run (I simply needed to copy a file), I found it much easier to call the commands on the PHP script by calling
exec("sudo cp /tmp/testfile1 /var/www/html/testfile2");
and enabling such transaction by editing (or rather adding) a permitting line to the sudoers by first calling sudo visudo
and adding the following line to the very end of it
www-data ALL=(ALL) NOPASSWD:/bin/cp /tmp/testfile1 /var/www/html/testfile2
All I wanted to do was to copy a file and I have been having problems with doing so because of the root password problem, and as you mentioned I did NOT want to expose the system to have no password for all root transactions.
Another option is YADDRESS.
The simplest solution is to add modal dialog styles to the top of the page or import css with this code:
<style>
.modal-dialog {
position:absolute;
top:50% !important;
transform: translate(0, -50%) !important;
-ms-transform: translate(0, -50%) !important;
-webkit-transform: translate(0, -50%) !important;
margin:auto 50%;
width:40%;
height:40%;
}
</style>
Modal declaration:
<div class="modal fade" id="exampleModalCenter" tabindex="-1" role="dialog" aria-labelledby="exampleModalCenterTitle" aria-hidden="true">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title" id="exampleModalLongTitle">Modal title</h5>
<button type="button" class="close" data-dismiss="modal" aria-label="Close">
<span aria-hidden="true">×</span>
</button>
</div>
<div class="modal-body">
...
</div>
<div class="modal-footer">
<button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
<button type="button" class="btn btn-primary">Save changes</button>
</div>
</div>
</div>
</div>
Modal usage:
<a data-toggle="modal" data-target="#exampleModalCenter">
...
</a>
In Java 8:
List<WorldLocation> locations = new ArrayList<>();

The following solution works for Android Marshmallow 6 (API 23, API 24, API 25, API 26, API 27, API 28). It also works in Xamarin.
LatLngBounds.Builder builder = new LatLngBounds.Builder();
//the include method will calculate the min and max bound.
builder.include(marker1.getPosition());
builder.include(marker2.getPosition());
builder.include(marker3.getPosition());
builder.include(marker4.getPosition());
LatLngBounds bounds = builder.build();
int width = getResources().getDisplayMetrics().widthPixels;
int height = getResources().getDisplayMetrics().heightPixels;
int padding = (int) (width * 0.10); // offset from edges of the map 10% of screen
CameraUpdate cu = CameraUpdateFactory.newLatLngBounds(bounds, width, height, padding);
mMap.animateCamera(cu);
If notepad is already started, you should write:
// import the function in your class
[DllImport ("User32.dll")]
static extern int SetForegroundWindow(IntPtr point);
//...
Process p = Process.GetProcessesByName("notepad").FirstOrDefault();
if (p != null)
{
IntPtr h = p.MainWindowHandle;
SetForegroundWindow(h);
SendKeys.SendWait("k");
}
GetProcessesByName
returns an array of processes, so you should get the first one (or find the one you want).
If you want to start notepad
and send the key, you should write:
Process p = Process.Start("notepad.exe");
p.WaitForInputIdle();
IntPtr h = p.MainWindowHandle;
SetForegroundWindow(h);
SendKeys.SendWait("k");
The only situation in which the code may not work is when notepad
is started as Administrator and your application is not.
You can catch it like any other exception:
try {
foo();
}
catch (const std::bad_alloc&) {
return -1;
}
Quite what you can usefully do from this point is up to you, but it's definitely feasible technically.
In general you cannot, and should not try, to respond to this error. bad_alloc
indicates that a resource cannot be allocated because not enough memory is available. In most scenarios your program cannot hope to cope with that, and terminating soon is the only meaningful behaviour.
Worse, modern operating systems often over-allocate: on such systems, malloc
and new
can return a valid pointer even if there is not enough free memory left – std::bad_alloc
will never be thrown, or is at least not a reliable sign of memory exhaustion. Instead, attempts to access the allocated memory will then result in a segmentation fault, which is not catchable (you can handle the segmentation fault signal, but you cannot resume the program afterwards).
The only thing you could do when catching std::bad_alloc
is to perhaps log the error, and try to ensure a safe program termination by freeing outstanding resources (but this is done automatically in the normal course of stack unwinding after the error gets thrown if the program uses RAII appropriately).
In certain cases, the program may attempt to free some memory and try again, or use secondary memory (= disk) instead of RAM but these opportunities only exist in very specific scenarios with strict conditions:
It’s exceedingly rare that applications have control over point 1 — userspace applications never do, it’s a system-wide setting that requires root permissions to change.1
OK, so let’s assume you’ve fixed point 1. What you can now do is for instance use a LRU cache for some of your data (probably some particularly large business objects that can be regenerated or reloaded on demand). Next, you need to put the actual logic that may fail into a function that supports retry — in other words, if it gets aborted, you can just relaunch it:
lru_cache<widget> widget_cache;
double perform_operation(int widget_id) {
std::optional<widget> maybe_widget = widget_cache.find_by_id(widget_id);
if (not maybe_widget) {
maybe_widget = widget_cache.store(widget_id, load_widget_from_disk(widget_id));
}
return maybe_widget->frobnicate();
}
…
for (int num_attempts = 0; num_attempts < MAX_NUM_ATTEMPTS; ++num_attempts) {
try {
return perform_operation(widget_id);
} catch (std::bad_alloc const&) {
if (widget_cache.empty()) throw; // memory error elsewhere.
widget_cache.remove_oldest();
}
}
// Handle too many failed attempts here.
But even here, using std::set_new_handler
instead of handling std::bad_alloc
provides the same benefit and would be much simpler.
1 If you’re creating an application that does control point 1, and you’re reading this answer, please shoot me an email, I’m genuinely curious about your circumstances.
new
in c++?The usual notion is that if new
operator cannot allocate dynamic memory of the requested size, then it should throw an exception of type std::bad_alloc
.
However, something more happens even before a bad_alloc
exception is thrown:
C++03 Section 3.7.4.1.3: says
An allocation function that fails to allocate storage can invoke the currently installed new_handler(18.4.2.2), if any. [Note: A program-supplied allocation function can obtain the address of the currently installed new_handler using the set_new_handler function (18.4.2.3).] If an allocation function declared with an empty exception-specification (15.4), throw(), fails to allocate storage, it shall return a null pointer. Any other allocation function that fails to allocate storage shall only indicate failure by throw-ing an exception of class std::bad_alloc (18.4.2.1) or a class derived from std::bad_alloc.
Consider the following code sample:
#include <iostream>
#include <cstdlib>
// function to call if operator new can't allocate enough memory or error arises
void outOfMemHandler()
{
std::cerr << "Unable to satisfy request for memory\n";
std::abort();
}
int main()
{
//set the new_handler
std::set_new_handler(outOfMemHandler);
//Request huge memory size, that will cause ::operator new to fail
int *pBigDataArray = new int[100000000L];
return 0;
}
In the above example, operator new
(most likely) will be unable to allocate space for 100,000,000 integers, and the function outOfMemHandler()
will be called, and the program will abort after issuing an error message.
As seen here the default behavior of new
operator when unable to fulfill a memory request, is to call the new-handler
function repeatedly until it can find enough memory or there is no more new handlers. In the above example, unless we call std::abort()
, outOfMemHandler()
would be called repeatedly. Therefore, the handler should either ensure that the next allocation succeeds, or register another handler, or register no handler, or not return (i.e. terminate the program). If there is no new handler and the allocation fails, the operator will throw an exception.
new_handler
and set_new_handler
?new_handler
is a typedef for a pointer to a function that takes and returns nothing, and set_new_handler
is a function that takes and returns a new_handler
.
Something like:
typedef void (*new_handler)();
new_handler set_new_handler(new_handler p) throw();
set_new_handler's parameter is a pointer to the function operator new
should call if it can't allocate the requested memory. Its return value is a pointer to the previously registered handler function, or null if there was no previous handler.
Given the behavior of new
a well designed user program should handle out of memory conditions by providing a proper new_handler
which does one of the following:
Make more memory available: This may allow the next memory allocation attempt inside operator new's loop to succeed. One way to implement this is to allocate a large block of memory at program start-up, then release it for use in the program the first time the new-handler is invoked.
Install a different new-handler: If the current new-handler can't make any more memory available, and of there is another new-handler that can, then the current new-handler can install the other new-handler in its place (by calling set_new_handler
). The next time operator new calls the new-handler function, it will get the one most recently installed.
(A variation on this theme is for a new-handler to modify its own behavior, so the next time it's invoked, it does something different. One way to achieve this is to have the new-handler modify static, namespace-specific, or global data that affects the new-handler's behavior.)
Uninstall the new-handler: This is done by passing a null pointer to set_new_handler
. With no new-handler installed, operator new
will throw an exception ((convertible to) std::bad_alloc
) when memory allocation is unsuccessful.
Throw an exception convertible to std::bad_alloc
. Such exceptions are not be caught by operator new
, but will propagate to the site originating the request for memory.
Not return: By calling abort
or exit
.

The timeout problem occurs when either the network is slow or many network calls are made using await
. These scenarios exceed the default timeout, i.e., 5000 ms. To avoid the timeout error, simply increase the timeout of globals that support a timeout. A list of globals and their signature can be found here.

My current choice is Razor. It is very clean and easy to read and keeps the view pages very easy to maintain. There is also intellisense support which is really great. ALos, when used with web helpers it is really powerful too.
To provide a simple sample:
@Model namespace.model
<!Doctype html>
<html>
<head>
<title>Test Razor</title>
</head>
<body>
<ul class="mainList">
@foreach(var x in ViewData.model)
{
<li>@x.PropertyName</li>
}
</ul>
</body>
And there you have it. That is very clean and easy to read. Granted, that's a simple example but even on complex pages and forms it is still very easy to read and understand.
As for the cons? Well so far (I'm new to this) when using some of the helpers for forms there is a lack of support for adding a CSS class reference which is a little annoying.
Thanks Nathj07
As others suggested, you can serialize and deserialize the whole list at once, which is simpler and seems to comply perfectly with what you intend to do.
In that case the serialization code becomes
ObjectOutputStream oos = null;
FileOutputStream fout = null;
try{
fout = new FileOutputStream("G:\\address.ser", true);
oos = new ObjectOutputStream(fout);
oos.writeObject(myClassList);
} catch (Exception ex) {
ex.printStackTrace();
} finally {
if(oos != null){
oos.close();
}
}
And deserialization becomes (assuming that myClassList is a list and hoping you will use generics):
ObjectInputStream objectinputstream = null;
try {
FileInputStream streamIn = new FileInputStream("G:\\address.ser");
objectinputstream = new ObjectInputStream(streamIn);
List<MyClass> readCase = (List<MyClass>) objectinputstream.readObject();
recordList.add(readCase);
System.out.println(recordList.get(i));
} catch (Exception e) {
e.printStackTrace();
} finally {
if(objectinputstream != null){
objectinputstream .close();
}
}
You can also deserialize several objects from a file, as you intended to:
ObjectInputStream objectinputstream = null;
try {
streamIn = new FileInputStream("G:\\address.ser");
objectinputstream = new ObjectInputStream(streamIn);
MyClass readCase = null;
do {
readCase = (MyClass) objectinputstream.readObject();
if(readCase != null){
recordList.add(readCase);
}
} while (readCase != null)
System.out.println(recordList.get(i));
} catch (Exception e) {
e.printStackTrace();
} finally {
if(objectinputstream != null){
objectinputstream .close();
}
}
Please do not forget to close stream objects in a finally clause (note: it can throw exception).
EDIT
As suggested in the comments, it should be preferable to use try with resources and the code should get quite simpler.
Here is the list serialization :
try(
FileOutputStream fout = new FileOutputStream("G:\\address.ser", true);
ObjectOutputStream oos = new ObjectOutputStream(fout);
){
oos.writeObject(myClassList);
} catch (Exception ex) {
ex.printStackTrace();
}
If only the columns are required then DataTable.Clone()
can be used. With Clone
function only the schema will be copied. But DataTable.Copy()
copies both the structure and data
E.g.
DataTable dt = new DataTable();
dt.Columns.Add("Column Name");
dt.Rows.Add("Column Data");
DataTable dt1 = dt.Clone();
DataTable dt2 = dt.Copy();
dt1
will have only the one column but dt2
will have one column with one row.
After all the above methods like turning OFF SSL certificate verification, turning ON only Use System Proxy and removing HTTP_PROXY and HTTPS_PROXY system environment variables, it worked.
Note: Had to restart the Postman app, since the environment variables were changed.
how can i return a array in a c++ method and how must i declare it? int[] test(void); ??
This sounds like a simple question, but in C++ you have quite a few options. Firstly, you should prefer...
std::vector<>
, which grows dynamically to however many elements you encounter at runtime, or
std::array<>
(introduced with C++11), which always stores a number of elements specified at compile time,
...as they manage memory for you, ensuring correct behaviour and simplifying things considerably:
std::vector<int> fn()
{
std::vector<int> x;
x.push_back(10);
return x;
}
std::array<int, 2> fn2() // C++11
{
return {3, 4};
}
void caller()
{
std::vector<int> a = fn();
const std::vector<int>& b = fn(); // extend lifetime but read-only
// b valid until scope exit/return
std::array<int, 2> c = fn2();
const std::array<int, 2>& d = fn2();
}
The practice of creating a const
reference to the returned data can sometimes avoid a copy, but normally you can just rely on Return Value Optimisation, or - for vector
but not array
- move semantics (introduced with C++11).
If you really want to use an inbuilt array (as distinct from the Standard library class called array
mentioned above), one way is for the caller to reserve space and tell the function to use it:
void fn(int x[], int n)
{
for (int i = 0; i < n; ++i)
x[i] = n;
}
void caller()
{
// local space on the stack - destroyed when caller() returns
int x[10];
fn(x, sizeof x / sizeof x[0]);
// or, use the heap, lives until delete[](p) called...
int* p = new int[10];
fn(p, 10);
}
Another option is to wrap the array in a structure, which - unlike raw arrays - are legal to return by value from a function:
struct X
{
int x[10];
};
X fn()
{
X x;
x.x[0] = 10;
// ...
return x;
}
void caller()
{
X x = fn();
}
Starting with the above, if you're stuck using C++03 you might want to generalise it into something closer to the C++11 std::array
:
template <typename T, size_t N>
struct array
{
T& operator[](size_t n) { return x[n]; }
const T& operator[](size_t n) const { return x[n]; }
size_t size() const { return N; }
// iterators, constructors etc....
private:
T x[N];
};
Another option is to have the called function allocate memory on the heap:
int* fn()
{
int* p = new int[2];
p[0] = 0;
p[1] = 1;
return p;
}
void caller()
{
int* p = fn();
// use p...
delete[] p;
}
To help simplify the management of heap objects, many C++ programmers use "smart pointers" that ensure deletion when the pointer(s) to the object leave their scopes. With C++11:
std::shared_ptr<int> p(new int[2], [](int* p) { delete[] p; } );
std::unique_ptr<int[]> p(new int[3]);
If you're stuck on C++03, the best option is to see if the boost library is available on your machine: it provides boost::shared_array
.
Yet another option is to have some static memory reserved by fn()
, though this is NOT THREAD SAFE, and means each call to fn()
overwrites the data seen by anyone keeping pointers from previous calls. That said, it can be convenient (and fast) for simple single-threaded code.
int* fn(int n)
{
static int x[2]; // clobbered by each call to fn()
x[0] = n;
x[1] = n + 1;
return x; // every call to fn() returns a pointer to the same static x memory
}
void caller()
{
int* p = fn(3);
// use p, hoping no other thread calls fn() meanwhile and clobbers the values...
// no clean up necessary...
}
If you will later know the length of the array you can create the initial array like this:
String[] array;
And later when you know the length you can finish initializing it like this
array = new String[42];
You will have to install the "Developer Tools" that are provided as optional packages in OS X installation disks.
Somewhere in your initialisation put this code.
Array.prototype.contains = function contains(obj) {
for (var i = 0; i < this.length; i++) {
if (this[i] === obj) {
return true;
}
}
return false;
};
Then, you can use it this way:
<li ng-class="{approved: selectedForApproval.contains(jobSet)}"></li>
You mean the ASCII ordinal value? Try type casting like this one:
int x = 'a';

pressing Enter when the focus in on a form control (input) normally triggers a submit
(onSubmit) event on the form itself (not the input) so you could bind your this.handleInput
to the form onSubmit.
Alternatively you could bind it to the blur
(onBlur) event on the input
which happens when the focus is removed (e.g. tabbing to the next element that can get focus)
Update January 2013: a brand new search has arrived!, based on elasticsearch.org:
A search for stat within the ruby repo will be expressed as stat repo:ruby/ruby
, and will now just workTM.
(the repo name is not case sensitive: test repo:wordpress/wordpress
returns the same as test repo:Wordpress/Wordpress
)
Will give:
And you have many other examples of search, based on followers, or on forks, or...
Update July 2012 (old days of Lucene search and poor code indexing, combined with broken GUI, kept here for archive):
The search (based on SolrQuerySyntax) is now more permissive and the dreaded "Invalid search query. Try quoting it.
" is gone when using the default search selector "Everything":)
(I suppose we can all than Tim Pease, which had in one of his objectives "hacking on improved search experiences for all GitHub properties", and I did mention this Stack Overflow question at the time ;) )
Here is an illustration of a grep within the ruby code: it will looks for repos and users, but also for what I wanted to search in the first place: the code!
Initial answer and illustration of the former issue (Sept. 2012 => March 2012)
You can use the advanced search GitHub form:
Code
, Repositories
or Users
from the drop-down and For instance, Use the repo:username/repo-name
directive to limit the search to a code repository.
The initial "Advanced Search
" page includes the section:
Code Search:
The Code search will look through all of the code publicly hosted on GitHub. You can also filter by :
- the language
language:
- the repository name (including the username)
repo:
- the file path
path:
So if you select the "Code
" search selector, then your query grepping for a text within a repo will work:
What is incredibly unhelpful from GitHub is that:
Code
"), you will get an error message:Invalid search query. Try quoting it.
" the error message doesn't help you at all.
No amount of "quoting it
" will get you out of this error.
once you get that error message, you don't get the sections reminding you of the right association between the search selectors ("Repositories
", "Users
" or "Language
") and the (right) search filters (here "repo:
").
Any further attempt you do won't display those associations (selectors-filters) back. Only the error message you see above...
The only way to get back those arrays is by clicking the "Advance Search
" icon:
the "Everything
" search selector, which is the default, is actually the wrong one for all of the search filters! Except "language:
"...
(You could imagine/assume that "Everything
" would help you to pick whatever search selector actually works with the search filter "repo:
", but nope. That would be too easy)
you cannot specify the search selector you want through the "Advance Search
" field alone!
(but you can for "language:
", even though "Search Language
" is another combo box just below the "Search for
" 'type' one...)
So, the user's experience usually is as follows:
Advanced Search
", glance over those sections of filters, and notice one you want to use: "repo:
"repo:jruby/jruby stat
", but with the default Search selector "Everything
"FAIL
! (and the arrays displaying the association "Selectors-Filters" is gone)Repositories
" ("Dah! I want to search within repositories...")FAIL
!Users
"), without even looking at said selector, just to give it one more try...FAIL
!So, to recap, if you want to "grep for something inside a Github project's code", as the OP Ben Humphreys, don't forget to select the "Code
" search selector...
To merge any number of raw objects
function merge_obj(){
foreach(func_get_args() as $a){
$objects[]=(array)$a;
}
return (object)call_user_func_array('array_merge', $objects);
}
I've ended up with the following working code:
RewriteEngine on
RewriteCond %{THE_REQUEST} /([^.]+)\.php [NC]
RewriteRule ^ /%1 [NC,L,R]
RewriteCond %{REQUEST_FILENAME}.php -f
RewriteRule ^ %{REQUEST_URI}.php [NC,L]
Use ByteArrayInputStream
:
InputStream is = new ByteArrayInputStream(decodedBytes);
I've looked around and the
display: table-cell;
vertical-align: middle;
seems to be the most popular solution

Not gonna happen with CSS only
Inline javascript
<a href='index.html'
onmouseover='this.style.textDecoration="none"'
onmouseout='this.style.textDecoration="underline"'>
Click Me
</a>
In a working draft of the CSS2 spec it was declared that you could use pseudo-classes inline like this:
<a href="http://www.w3.org/Style/CSS"
style="{color: blue; background: white} /* a+=0 b+=0 c+=0 */
:visited {color: green} /* a+=0 b+=1 c+=0 */
:hover {background: yellow} /* a+=0 b+=1 c+=0 */
:visited:hover {color: purple} /* a+=0 b+=2 c+=0 */
">
</a>
but it was never implemented in the release of the spec as far as I know.

data
is not an array, it is an object with an array of products so iterate over data.products
var allProducts = data.products.map(function (item) {
return new getData(item);
});
If you want to use fetch instead:
var myImage = document.querySelector('img');
fetch('flowers.jpg').then(function(response) {
return response.blob();
}).then(function(myBlob) {
var objectURL = URL.createObjectURL(myBlob);
myImage.src = objectURL;
});

It looks like your 'trainData' is a list of strings:
['-214' '-153' '-58' ..., '36' '191' '-37']
Change your 'trainData' to a numeric type.

}
}
Next time, Please try providing some code.
The accepted answer didn't work for me on Internet Explorer 9. I checked it and the browser detection was not working properly, it detected ff (firefox) when i was at Internet Explorer.
I just did this change:
if ($.browser.msie)
Instead of:
if (br == "ie") {
The resulting code is this one:
function insertAtCaret(areaId,text) {
var txtarea = document.getElementById(areaId);
var scrollPos = txtarea.scrollTop;
var strPos = 0;
var br = ((txtarea.selectionStart || txtarea.selectionStart == '0') ?
"ff" : (document.selection ? "ie" : false ) );
if ($.browser.msie) {
txtarea.focus();
var range = document.selection.createRange();
range.moveStart ('character', -txtarea.value.length);
strPos = range.text.length;
}
else if (br == "ff") strPos = txtarea.selectionStart;
var front = (txtarea.value).substring(0,strPos);
var back = (txtarea.value).substring(strPos,txtarea.value.length);
txtarea.value=front+text+back;
strPos = strPos + text.length;
if (br == "ie") {
txtarea.focus();
var range = document.selection.createRange();
range.moveStart ('character', -txtarea.value.length);
range.moveStart ('character', strPos);
range.moveEnd ('character', 0);
range.select();
}
else if (br == "ff") {
txtarea.selectionStart = strPos;
txtarea.selectionEnd = strPos;
txtarea.focus();
}
txtarea.scrollTop = scrollPos;
}
Another reason to the error may be if you are running a cron job that updates a subversion working copy and then has attempted to run a versioned script that was in a conflicted state after the update...
Look at ?par
for the various graphics parameters.
In general cex
controls size, col
controls colour. If you want to control the colour of a label, the par
is col.lab
, the colour of the axis annotations col.axis
, the colour of the main
text, col.main
etc. The names are quite intuitive, once you know where to begin.
For example
x <- 1:10
y <- 1:10
plot(x , y,xlab="x axis", ylab="y axis", pch=19, col.axis = 'blue', col.lab = 'red', cex.axis = 1.5, cex.lab = 2)
If you need to change the colour / style of the surrounding box and axis lines, then look at ?axis
or ?box
, and you will find that you will be using the same parameter names within calls to box
and axis.
You have a lot of control to make things however you wish.
eg
plot(x , y,xlab="x axis", ylab="y axis", pch=19, cex.lab = 2, axes = F,col.lab = 'red')
box(col = 'lightblue')
axis(1, col = 'blue', col.axis = 'purple', col.ticks = 'darkred', cex.axis = 1.5, font = 2, family = 'serif')
axis(2, col = 'maroon', col.axis = 'pink', col.ticks = 'limegreen', cex.axis = 0.9, font =3, family = 'mono')
Which is seriously ugly, but shows part of what you can control
I'm surprised that nobody has mentioned it but Pygments is able to make an educated guess about the mime-type of, particularly, text documents.
Pygments is actually a Python syntax highlighting library but is has a method that will make an educated guess about which of 500 supported document types your document is. i.e. c++ vs C# vs Python vs etc
import inspect
def _test(text: str):
from pygments.lexers import guess_lexer
lexer = guess_lexer(text)
mimetype = lexer.mimetypes[0] if lexer.mimetypes else None
print(mimetype)
if __name__ == "__main__":
# Set the text to the actual defintion of _test(...) above
text = inspect.getsource(_test)
print('Text:')
print(text)
print()
print('Result:')
_test(text)
Output:
Text:
def _test(text: str):
from pygments.lexers import guess_lexer
lexer = guess_lexer(text)
mimetype = lexer.mimetypes[0] if lexer.mimetypes else None
print(mimetype)
Result:
text/x-python
Now, it's not perfect, but if you need to be able to tell which of 500 document formats are being used, this is pretty darn useful.
According to documentation it is:
spring.jpa.show-sql=true # Enable logging of SQL statements.
Use lodash. In ES6 syntax:
import isEqual from 'lodash/isEqual';
let equal = isEqual([1,2], [1,2]); // true
Or previous js versions:
var isEqual = require('lodash/isEqual');
var equal = isEqual([1,2], [1,2]); // true
For me I just added the bellow xml code in the POM.xml file. And after I dit **right click in the project -> Maven -> Update Project and I checked Force Update of Snapshots/Releases ** and every thing worked

With argc
(argument count) and argv
(argument vector) you can get the number and the values of passed arguments when your application has been launched.
This way you can use parameters (such as -version
) when your application is started to act a different way.
But you can also use int main(void)
as a prototype in C.
There is a third (less known and nonstandard) prototype with a third argument which is envp
. It contains environment variables.
Resources:
Initializer block is just like any bits of code; it's not "attached" to any field/method preceding it. To assign values to fields, you have to explicitly use the field as the lhs of an assignment statement.
private int lineCount; {
try{
lineCount = LineCounter.countLines(sFileName);
/*^^^^^^^*/
}
catch(IOException ex){
System.out.println (ex.toString());
System.out.println("Could not find file " + sFileName);
}
}
Also, your countLines
can be made simpler:
public static int countLines(String filename) throws IOException {
LineNumberReader reader = new LineNumberReader(new FileReader(filename));
while (reader.readLine() != null) {}
reader.close();
return reader.getLineNumber();
}
Based on my test, it looks like you can getLineNumber()
after close()
.
file1=/tmp/main.one.two.sh
t=$(basename "$file1") # output is main.one.two.sh
name=$(echo "$file1" | sed -e 's/\.[^.]*$//') # output is /tmp/main.one.two
name=$(echo "$t" | sed -e 's/\.[^.]*$//') # output is main.one.two
use whichever you want. Here I assume that last .
(dot) followed by text is extension.
Make another div and add both 'dummy' and 'img-container' inside the div
Do HTML and CSS like follows
html , body {height:100%;}_x000D_
.responsive-container { height:100%; display:table; text-align:center; width:100%;}_x000D_
.inner-container {display:table-cell; vertical-align:middle;}
_x000D_
<div class="responsive-container">_x000D_
<div class="inner-container">_x000D_
<div class="dummy">Sample</div>_x000D_
<div class="img-container">_x000D_
Image tag_x000D_
</div>_x000D_
</div> _x000D_
</div>
_x000D_
Instead of 100% for the 'responsive-container' you can give the height that you want.,
Here's my setup: I am on Ubuntu 9.10.
Now, Here's what I did.
Create an xml file "myapp.xml" (i guess it must have the same name as the name of the folder in step 2) inside /etc/tomcat6/Catalina/localhost with the following contents.
< Context path="/myapp" docBase="/usr/share/tomcat6-myapp/myapp" />
This xml is called the 'Deployment Descriptor' which Tomcat reads and automatically deploys your app named "myapp".
Now go to http://localhost:8080/myapp in your browser - the index.html gets picked up by tomcat and is shown.
I hope this helps!

Why don't you disable the view cache with cache-view="false"?
In your view add this to the ion-nav-view like that:
<ion-nav-view name="other" cache-view="false"></ion-nav-view>
Or in your stateProvider:
$stateProvider.state('other', {
cache: false,
url : '/other',
templateUrl : 'templates/other/other.html'
})
Either one will make your controller being called always.
This is an old answer with deprecated and hacky way of overcoming some specific content resolver pain points. Take it with some huge grains of salt and use the proper openInputStream API if at all possible.
You can use the Content Resolver to get a file://
path from the content://
URI:
String filePath = null;
Uri _uri = data.getData();
Log.d("","URI = "+ _uri);
if (_uri != null && "content".equals(_uri.getScheme())) {
Cursor cursor = this.getContentResolver().query(_uri, new String[] { android.provider.MediaStore.Images.ImageColumns.DATA }, null, null, null);
cursor.moveToFirst();
filePath = cursor.getString(0);
cursor.close();
} else {
filePath = _uri.getPath();
}
Log.d("","Chosen path = "+ filePath);
The primary flag seems to only work for vagrant ssh
for me.
In the past I have used the following method to hack around the issue.
# stage box intended for configuration closely matching production if ARGV[1] == 'stage' config.vm.define "stage" do |stage| box_setup stage, \ "10.9.8.31", "deploy/playbook_full_stack.yml", "deploy/hosts/vagrant_stage.yml" end end
I realize this is a very old post and has some great answers already, but I wanted to make a simple MCVE to demonstrate one such approach and allow new coders a way to quickly see the concept in action.
In this example, we will use 5 files:
All files are listed in their entirety at the bottom of this post.
The Goal: To demonstrate passing values from Controller1
to Controller2
and vice versa.
The Program Flow:
TextField
, a Button
, and a Label
. When the Button
is clicked, the second window is loaded and displayed, including the text entered in the TextField
.TextField
, a Button
, and a Label
. The Label
will display the text entered in the TextField
on the first scene.TextField
and clicking its Button
, the first scene's Label
is updated to show the entered text.This is a very simple demonstration and could surely stand for some improvement, but should make the concept very clear.
The code itself is also commented with some details of what is happening and how.

It's happening because the @valerio-vaudi said.
Your problem is the dependency of spring batch spring-boot-starter-batch that has a spring-boot-starter-jdbc transitive maven dependency.
But you can resolve it set the primary datasource with your configuration
@Primary
@Bean(name = "dataSource")
@ConfigurationProperties(prefix = "spring.datasource")
public DataSource getDataSource() {
return DataSourceBuilder.create().build();
}
@Bean
public JdbcTemplate jdbcTemplate(DataSource dataSource) {
return new JdbcTemplate(dataSource);
}
First I'd check to verify it is listening on the IPs you expect it to be:
netstat -nlpt | grep 6379
Depending on how you start/stop you may not have actually restarted the instance when you thought you had. The netstat will tell you if it is listening where you think it is. If not, restart it and be sure it restarts. If it restarts and still is not listening where you expect, check your config file just to be sure.
After establishing it is listening where you expect it to, from a remote node which should have access try:
redis-cli -h REMOTE.HOST ping
You could also try that from the local host but use the IP you expect it to be listening on instead of a hostname or localhost. You should see it PONG in response in both cases.
If not, your firewall(s) is/are blocking you. This would be either the local IPTables or possibly a firewall in between the nodes. You could add a logging statement to your IPtables configuration to log connections over 6379 to see what is happening. Also, trying he redis ping from local and non-local to the same IP should be illustrative. If it responds locally but not remotely, I'd lean toward an intervening firewall depending on the complexity of your on-node IP Tables rules.
I created this simple example from different search results on the internet.
public static ServiceHost CreateServiceHost(Type serviceInterface, Type implementation)
{
//Create base address
string baseAddress = "net.pipe://localhost/MyService";
ServiceHost serviceHost = new ServiceHost(implementation, new Uri(baseAddress));
//Net named pipe
NetNamedPipeBinding binding = new NetNamedPipeBinding { MaxReceivedMessageSize = 2147483647 };
serviceHost.AddServiceEndpoint(serviceInterface, binding, baseAddress);
//MEX - Meta data exchange
ServiceMetadataBehavior behavior = new ServiceMetadataBehavior();
serviceHost.Description.Behaviors.Add(behavior);
serviceHost.AddServiceEndpoint(typeof(IMetadataExchange), MetadataExchangeBindings.CreateMexNamedPipeBinding(), baseAddress + "/mex/");
return serviceHost;
}
Using the above URI I can add a reference in my client to the web service.
There are several problems here, so I'll start with my usual high-level advice: Start small and simple, add complexity a little at a time, test at every step, and never add to code that doesn't work. (I really ought to have that hotkeyed.)
You're mixing Make syntax and shell syntax in a way that is just dizzying. You should never have let it get this big without testing. Let's start from the outside and work inward.
UNAME := $(shell uname -m)
all:
$(info Checking if custom header is needed)
ifeq ($(UNAME), x86_64)
... do some things to build unistd_32.h
endif
@make -C $(KDIR) M=$(PWD) modules
So you want unistd_32.h built (maybe) before you invoke the second make
, you can make it a prerequisite. And since you want that only in a certain case, you can put it in a conditional:
ifeq ($(UNAME), x86_64)
all: unistd_32.h
endif
all:
@make -C $(KDIR) M=$(PWD) modules
unistd_32.h:
... do some things to build unistd_32.h
Now for building unistd_32.h
:
F1_EXISTS=$(shell [ -e /usr/include/asm/unistd_32.h ] && echo 1 || echo 0 )
ifeq ($(F1_EXISTS), 1)
$(info Copying custom header)
$(shell sed -e 's/__NR_/__NR32_/g' /usr/include/asm/unistd_32.h > unistd_32.h)
else
F2_EXISTS=$(shell [[ -e /usr/include/asm-i386/unistd.h ]] && echo 1 || echo 0 )
ifeq ($(F2_EXISTS), 1)
$(info Copying custom header)
$(shell sed -e 's/__NR_/__NR32_/g' /usr/include/asm-i386/unistd.h > unistd_32.h)
else
$(error asm/unistd_32.h and asm-386/unistd.h does not exist)
endif
endif
You are trying to build unistd.h
from unistd_32.h
; the only trick is that unistd_32.h
could be in either of two places. The simplest way to clean this up is to use a vpath
directive:
vpath unistd.h /usr/include/asm /usr/include/asm-i386
unistd_32.h: unistd.h
sed -e 's/__NR_/__NR32_/g' $< > $@
For Excel 2010 it should be UTF-8. Instruction by MS :
http://msdn.microsoft.com/en-us/library/bb507946:
"The basic document structure of a SpreadsheetML document consists of the Sheets and Sheet elements, which reference the worksheets in the Workbook. A separate XML file is created for each Worksheet. For example, the SpreadsheetML for a workbook that has two worksheets name MySheet1 and MySheet2 is located in the Workbook.xml file and is shown in the following code example.
<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>
<workbook xmlns=http://schemas.openxmlformats.org/spreadsheetml/2006/main xmlns:r="http://schemas.openxmlformats.org/officeDocument/2006/relationships">
<sheets>
<sheet name="MySheet1" sheetId="1" r:id="rId1" />
<sheet name="MySheet2" sheetId="2" r:id="rId2" />
</sheets>
</workbook>
The worksheet XML files contain one or more block level elements such as SheetData. sheetData represents the cell table and contains one or more Row elements. A row contains one or more Cell elements. Each cell contains a CellValue element that represents the value of the cell. For example, the SpreadsheetML for the first worksheet in a workbook, that only has the value 100 in cell A1, is located in the Sheet1.xml file and is shown in the following code example.
<?xml version="1.0" encoding="UTF-8" ?>
<worksheet xmlns="http://schemas.openxmlformats.org/spreadsheetml/2006/main">
<sheetData>
<row r="1">
<c r="A1">
<v>100</v>
</c>
</row>
</sheetData>
</worksheet>

Lots of answers but no substance, like robots doing cut and paste on what's on their system. There is no need to set GOROOT
as an environment variable. However, there is a beneficial need to set the GOPATH
environment variable, and if not set it defaults to ${HOME}/go/
folder.
It is the PATH
environment variable that you must pay attention because this variable is the variable that can change your go version
. Not GOROOT
! Forget GOROOT
.
Now, if you switch or change to a new go version
, your downloaded packages will use the default $HOME/go
folder and it will mixed-up with whatever your previous go version
was. This is not good.
Therefore, this is where GOPATH
you need to define in order to isolate downloaded packages of the new go version
.
In summary, forget GOROOT
. Think more on GOPATH
.
On alternativ answer is this.
if you have and array like this: var contacts = [bob, mary];
and you want to put another array in this array, you can do that in this way:
Declare the function constructor
function add (firstName,lastName,email,phoneNumber) {
this.firstName = firstName;
this.lastName = lastName;
this.email = email;
this.phoneNumber = phoneNumber;
}
make the object from the function:
var add1 = new add("Alba","Fas","[email protected]","[098] 654365364");
and add the object in to the array:
contacts[contacts.length] = add1;
What if the incoming changes are the ones you want? I'm unable to run svn resolve --accept theirs-full

This problem will happen if you delete using PlaylistadMap modal instead of PlayList. in this case FetchType = Lazy is not the right option. It will not throw any exception but only data from PlaylistadMap will get deleted, the data in PlayList will remain in the table. check that also.
Why has no one simply listed.
$(element).attr("class").split(/\s+/);

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;
}
}
It's really simple to fix the issue, however keep in mind that you should fork and commit your changes for each library you are using in their repositories to help others as well.
Let's say you have something like this in your code:
$str = "test";
echo($str{0});
since PHP 7.4 curly braces method to get individual characters inside a string has been deprecated, so change the above syntax into this:
$str = "test";
echo($str[0]);
Fixing the code in the question will look something like this:
public function getRecordID(string $zoneID, string $type = '', string $name = ''): string
{
$records = $this->listRecords($zoneID, $type, $name);
if (isset($records->result[0]->id)) {
return $records->result[0]->id;
}
return false;
}
Reload collectionView on Main Thread
DispatchQueue.main.async {
self.collectionView.reloadData()
}
Strictly,
other = s if s is not None else "default value"
Otherwise, s = False
will become "default value"
, which may not be what was intended.
If you want to make this shorter, try:
def notNone(s,d):
if s is None:
return d
else:
return s
other = notNone(s, "default value")
IMO, the best seems to use sql statements only to copy that row, while at the same time only referencing the columns you must and want to change.

in one atomic operation.For those looking to use axios-mock-adapter in place of the mockfetch example in the Redux documentation for async testing, I successfully used the following:
describe('SignInUser', () => {
var history = {
push: function(str) {
expect(str).toEqual('/feed');
}
}
it('Dispatches authorization', () => {
let mock = new MockAdapter(axios);
mock.onPost(`${ROOT_URL}/auth/signin`, {
email: '[email protected]',
password: 'test'
}).reply(200, {token: 'testToken' });
const expectedActions = [ { type: types.AUTH_USER } ];
const store = mockStore({ auth: [] });
return store.dispatch(actions.signInUser({
email: '[email protected]',
password: 'test',
}, history)).then(() => {
expect(store.getActions()).toEqual(expectedActions);
});
});
In order to test a successful case for signInUser
in file actions/index.js:
export const signInUser = ({ email, password }, history) => async dispatch => {
const res = await axios.post(`${ROOT_URL}/auth/signin`, { email, password })
.catch(({ response: { data } }) => {
...
});
if (res) {
dispatch({ type: AUTH_USER }); // Test verified this
localStorage.setItem('token', res.data.token); // Test mocked this
history.push('/feed'); // Test mocked this
}
}
Given that this is being done with jest, the localstorage call had to be mocked. This was in file src/setupTests.js:
const localStorageMock = {
removeItem: jest.fn(),
getItem: jest.fn(),
setItem: jest.fn(),
clear: jest.fn()
};
global.localStorage = localStorageMock;
Use:
var hovered = $("#parent").find("#element:hover").length;
jQuery 1.9+
You could use a bit of jQuery:
$('input:radio').click(function(){
$('label#' + $(this).attr('id')).toggleClass('checkedClass'); // checkedClass is defined in your CSS
});
You'd need to make sure your checked radio buttons have the correct class on page load as well.
C++ style casts are checked by the compiler. C style casts aren't and can fail at runtime.
Also, c++ style casts can be searched for easily, whereas it's really hard to search for c style casts.
Another big benefit is that the 4 different C++ style casts express the intent of the programmer more clearly.
When writing C++ I'd pretty much always use the C++ ones over the the C style.
Eval is used to bind to an UI item that is setup to be read-only (eg: a label or a read-only text box), i.e., Eval is used for one way binding - for reading from a database into a UI field.
It is generally used for late-bound data (not known from start) and usually bound to the smallest part of the data-bound control that contains a whole record. The Eval method takes the name of a data field and returns a string containing the value of that field from the current record in the data source. You can supply an optional second parameter to specify a format for the returned string. The string format parameter uses the syntax defined for the Format method of the String class.
In my case, it was due to an input in an array at an index equal to the length of the array.
string x[5];
for(int i=1; i<=5; i++){
cin>>x[i];
}
x[5] is being accessed which is not present.
You can build your class files within the VS Command prompt (so that all required environment variables are loaded), not the default Windows command window.

If this is your detail.html
I don't see where do you load detail.js
?
Maybe this
<script src="js/index.js"></script>
should be this
<script src="js/detail.js"></script>
?
I made a simple function, maybe someone can use it
function secsToTime(secs){
function format(number){
if(number===0){
return '00';
}else {
if (number < 10) {
return '0' + number
} else{
return ''+number;
}
}
}
var minutes = Math.floor(secs/60)%60;
var hours = Math.floor(secs/(60*60))%24;
var days = Math.floor(secs/(60*60*24));
var seconds = Math.floor(secs)%60;
return (days>0? days+"d " : "")+format(hours)+':'+format(minutes)+':'+format(seconds);
}
this can generate the followings outputs:
It can also be as simple as this.

Yes.
However, if you need to use Application.DoEvents

I tried all of these and could not get my break-point working...
What i did to fix this issue was
In the page where my break-point was not hitting, i selected the folder > add an existing item and then select the page from its save path. This allowed the break point to start working.
Possible solution
Based on Jürgen Weigert's answer, I have some improvement:
docker build -t xeyes - << __EOF__
FROM debian
RUN apt-get update
RUN apt-get install -qqy x11-apps
ENV DISPLAY :0
CMD xeyes
__EOF__
XSOCK=/tmp/.X11-unix
XAUTH_DIR=/tmp/.docker.xauth
XAUTH=$XAUTH_DIR/.xauth
mkdir -p $XAUTH_DIR && touch $XAUTH
xauth nlist $DISPLAY | sed -e 's/^..../ffff/' | xauth -f $XAUTH nmerge -
docker run -ti -v $XSOCK:$XSOCK -v $XAUTH_DIR:$XAUTH_DIR -e XAUTHORITY=$XAUTH xeyes
The only difference is that it creates a directory $XAUTH_DIR which is used to place $XAUTH file and mount $XAUTH_DIR directory instead of $XAUTH file into docker container.
The benefit of this method is that you can write a command in /etc/rc.local which is to create a empty folder named $XAUTH_DIR in /tmp and change its mode to 777.
tr '\n' '\000' < /etc/rc.local | sudo tee /etc/rc.local >/dev/null
sudo sed -i 's|\x00XAUTH_DIR=.*\x00\x00|\x00|' /etc/rc.local >/dev/null
tr '\000' '\n' < /etc/rc.local | sudo tee /etc/rc.local >/dev/null
sudo sed -i 's|^exit 0.*$|XAUTH_DIR=/tmp/.docker.xauth; rm -rf $XAUTH_DIR; install -m 777 -d $XAUTH_DIR\n\nexit 0|' /etc/rc.local
When system restart, before user login, docker will mount the $XAUTH_DIR directory automatically if container's restart policy is "always". After user login, you can write a command in ~/.profile which is to create $XAUTH file, then the container will automatically use this $XAUTH file.
tr '\n' '\000' < ~/.profile | sudo tee ~/.profile >/dev/null
sed -i 's|\x00XAUTH_DIR=.*-\x00|\x00|' ~/.profile
tr '\000' '\n' < ~/.profile | sudo tee ~/.profile >/dev/null
echo "XAUTH_DIR=/tmp/.docker.xauth; XAUTH=\$XAUTH_DIR/.xauth; touch \$XAUTH; xauth nlist \$DISPLAY | sed -e 's/^..../ffff/' | xauth -f \$XAUTH nmerge -" >> ~/.profile
Afterall, the container will automatically get the Xauthority file every time the system restart and user login.
To add a unique key use :
alter table your_table add UNIQUE(target_column_name);
To remove a unique key use:
alter table your_table drop INDEX target_column_name;
Methods Where authenticity_token
is required
authenticity_token
is required in case of idempotent methods like post, put and delete, Because Idempotent methods are affecting to data.
Why It is Required
It is required to prevent from evil actions. authenticity_token is stored in session, whenever a form is created on web pages for creating or updating to resources then a authenticity token is stored in hidden field and it sent with form on server. Before executing action user sent authenticity_token is cross checked with
authenticity_token
stored in session. Ifauthenticity_token
is same then process is continue otherwise it does not perform actions.
In my case this is incorrect/improper dependency

A keystore needs a keystore file. The KeyStore
class needs a FileInputStream
. But if you supply null (instead of FileInputStream
instance) an empty keystore will be loaded. Once you create a keystore, you can verify its integrity using keytool
.
Following code creates an empty keystore with empty password
KeyStore ks2 = KeyStore.getInstance("jks"); ks2.load(null,"".toCharArray()); FileOutputStream out = new FileOutputStream("C:\\mykeytore.keystore"); ks2.store(out, "".toCharArray());
Once you have the keystore, importing certificate is very easy. Checkout this link for the sample code.

or latest. Once after doing setup in cmd start with mvn clean install then mvn org.jacoco:jacoco-maven-plugin:prepare-agent install (Check on project's target folder whether jacoco.exec is created) & then do mvn sonar:sonar , this is what I've tried please let me know if some other best possible solution available.Hope this helps!!

For whatever reason I have had issues with some of these answers, I've went and written a couple helper functions for myself, so if you have problems like I did, give these a try.
def bin_string_to_bin_value(input):
highest_order = len(input) - 1
result = 0
for bit in input:
result = result + int(bit) * pow(2,highest_order)
highest_order = highest_order - 1
return bin(result)
def hex_string_to_bin_string(input):
lookup = {"0" : "0000", "1" : "0001", "2" : "0010", "3" : "0011", "4" : "0100", "5" : "0101", "6" : "0110", "7" : "0111", "8" : "1000", "9" : "1001", "A" : "1010", "B" : "1011", "C" : "1100", "D" : "1101", "E" : "1110", "F" : "1111"}
result = ""
for byte in input:

They seem to work well.

Let's say you have the DLLs build for both platforms, and they are in the following location:
C:\whatever\x86\whatever.dll
C:\whatever\x64\whatever.dll
You simply need to edit your .csproj file from this:
<HintPath>C:\whatever\x86\whatever.dll</HintPath>
To this:
<HintPath>C:\whatever\$(Platform)\whatever.dll</HintPath>
You should then be able to build your project targeting both platforms, and MSBuild will look in the correct directory for the chosen platform.

Another problem is when eclipse doesn't have write access to your src folder. Change the security permission and make sure "Authenticated Users" are added with all permissions checked but Full Control & Special Permissions.
Using the hashmap of weak reference approach, described above, and in http://developer.android.com/guide/faq/framework.html seems problematic to me. How are entire entries reclaimed, not just the map value? What scope do you allocate it in? As the framework is in control of the Activity lifecycle, having one of the participating Activities own it risks runtime errors when the owner is destroyed in advance of its clients. If the Application owns it, some Activity must explicitly remove the entry to avoid the hashmap from holding on to entries with a valid key and a potentially garbaged collected weak reference. Furthermore, what should a client do when the value returned for a key is null?
It seems to me that a WeakHashMap owned by the Application or within a singleton is a better choice. An value in the map is accessed via a key object, and when no strong references to the key exist (i.e. all Activities are done with the key and what it maps to), GC can reclaim the map entry.
STATICFILES_DIRS
is used in development and STATIC_ROOT
in production,
STATICFILES_DIRS
and STATIC_ROOT

If you need to use the exact same static folder in development and production, try this method

import socket
HOSTNAME = socket.gethostname()
# if hostname same as production url name use STATIC_ROOT
if HOSTNAME == 'www.example.com':
STATIC_ROOT = os.path.join(BASE_DIR, "static/")
else:
STATICFILES_DIRS = [
os.path.join(BASE_DIR, 'static/'),

For me I had setup my remote repo with an SSH key but git could not find them because the HOMEDRIVE environment variable was automatically getting set to a network share due to my company's domain policy. Changing that environment variable in my shell prior to launching code .
caused VSCode to inherit the correct environment variable and viola no more connection errors in the git output window.
Now I just have to figure out how to override the domain policy so HOMEDRIVE is always pointing to my local c:\users\marvhen
directory which is the default location for the .ssh
directory.
In advance of my questions being answered, this is how I'd go about it:
Minimize the number of statements and the work they do issued in relative terms.
All scenarios assume you have a table of IDs (PURGE_IDS
) to delete from TABLE_1
, TABLE_2
, etc.
Consider Using CREATE TABLE AS SELECT for really large deletes
If there's no concurrent activity, and you're deleting 30+ % of the rows in one or more of the tables, don't delete; perform a create table as select
with the rows you wish to keep, and swap the new table out for the old table. INSERT /*+ APPEND */ ... NOLOGGING
is surprisingly cheap if you can afford it. Even if you do have some concurrent activity, you may be able to use Online Table Redefinition to rebuild the table in-place.
Don't run DELETE statements you know won't delete any rows
If an ID value exists in at most one of the six tables, then keep track of which IDs you've deleted - and don't try to delete those IDs from any of the other tables.
CREATE TABLE TABLE1_PURGE NOLOGGING
AS
SELECT ID FROM PURGE_IDS INNER JOIN TABLE_1 ON PURGE_IDS.ID = TABLE_1.ID;
DELETE FROM TABLE1 WHERE ID IN (SELECT ID FROM TABLE1_PURGE);
DELETE FROM PURGE_IDS WHERE ID IN (SELECT ID FROM TABLE1_PURGE);
DROP TABLE TABLE1_PURGE;
and repeat.
Manage Concurrency if you have to
Another way is to use PL/SQL looping over the tables, issuing a rowcount-limited delete statement. This is most likely appropriate if there's significant insert/update/delete concurrent load against the tables you're running the deletes against.
declare
l_sql varchar2(4000);
begin
for i in (select table_name from all_tables
where table_name in ('TABLE_1', 'TABLE_2', ...)
order by table_name);
loop
l_sql := 'delete from ' || i.table_name ||
' where id in (select id from purge_ids) ' ||
' and rownum <= 1000000';
loop

You can convert the list of passed values into a table valued parameter and then select against this list
DECLARE @list NVARCHAR(MAX)
SET @list = '1,2,5,7,10';
DECLARE @pos INT
DECLARE @nextpos INT
DECLARE @valuelen INT
DECLARE @tbl TABLE (number int NOT NULL)
SELECT @pos = 0, @nextpos = 1;
WHILE @nextpos > 0
BEGIN
SELECT @nextpos = charindex(',', @list, @pos + 1)
SELECT @valuelen = CASE WHEN @nextpos > 0
THEN @nextpos
ELSE len(@list) + 1
END - @pos - 1
INSERT @tbl (number)
VALUES (convert(int, substring(@list, @pos + 1, @valuelen)))
SELECT @pos = @nextpos;
END
SELECT * FROM DBTable WHERE id IN (SELECT number FROM @tbl);
In this example the string passed in '1,2,5,7,10' is split by the commas and each value is added as a new row within the @tbl
table variable. This can then be selected against using standard SQL.
If you intend to reuse this functionality you could go further and convert this into a function.

This is a really obvious answer/rookie mistake, but I thought I would just put it here in case it might help someone. So my structure was that a had a Website in IIS with the frontend as one application underneath the website and the backend was the other. The backend application had six seperate api applications sitting beneath it. I had forgotten to convert each of the api folders to applications within IIS and of course this was causing the routes to my api endpoints to return a 404.0 error.
My Point: Check the simple stuff first! Make sure that you have converted all folders to applications in IIS where that is required for your website to function correctly.
Maybe you don't need this logic for a responsive behavior.
E.g.
placement: 'auto left'
Bootstrap 3 has auto value for placement. Bootstrap doc:
When "auto" is specified, it will dynamically reorient the tooltip. For example, if placement is "auto left", the tooltip will display to the left when possible, otherwise it will display right.
Remember that in git
you have:
HEAD
pointer, which tells you what commit you're working onPlease include detailed explanations about:
--hard
,--soft
and--merge
;
In increasing order of dangerous-ness:
--soft
moves HEAD
but doesn't touch the staging area or the working tree.--mixed
moves HEAD
and updates the staging area, but not the working tree.--merge
moves HEAD
, resets the staging area, and tries to move all the changes in your working tree into the new working tree.--hard
moves HEAD
and adjusts your staging area and working tree to the new HEAD
, throwing away everything.concrete use cases and workflows;
--soft
when you want to move to another commit and patch things up without "losing your place". It's pretty rare that you need this.--
# git reset --soft example
touch foo // Add a file, make some changes.
git add foo //
git commit -m "bad commit message" // Commit... D'oh, that was a mistake!
git reset --soft HEAD^ // Go back one commit and fix things.
git commit -m "good commit" // There, now it's right.
--
Use --mixed
(which is the default) when you want to see what things look like at another commit, but you don't want to lose any changes you already have.
Use --merge
when you want to move to a new spot but incorporate the changes you already have into that the working tree.
Use --hard
to wipe everything out and start a fresh slate at the new commit.

From GC Performance Tuning training documents of Oracle:
-Xmn[size]: Size of young generation heap space.
Applications with emphasis on performance tend to use -Xmn to size the young generation, because it combines the use of -XX:MaxNewSize and -XX:NewSize and almost always explicitly sets -XX:PermSize and -XX:MaxPermSize to the same value.
In short, it sets the NewSize and MaxNewSize values of New generation to the same value.
Best way to install Go on Ubuntu is to download required version from here. Here you could have all stable and releases, along with archived versions.
after downloading you selected version you can follow further steps, i will suggest you to download tar.gz format for ubuntu machine:
sudo rm -rf /usr/local/go /usr/local/gocache
this will remove all the local go code base but wait something more we have to do to remove fully from local, i was missing this step and it took so much time until I understood what i am missing so here is the purge stuff to remove from list
sudo apt-get purge golang
or
sudo apt remove golang-go
tar -C /usr/local -xzf go1.10.8.linux-amd64.tar.gz
GOROOT
variable value you can check the value by go env
if not set then export PATH=$PATH:/usr/local/go
/home/yourusername/go/test.php
if you haven't changed set GOPATH
value:package main import "fmt" func main() { fmt.Println("hello world") }
go run test.go
i hope it works for you!!
In Node.js, __dirname
is always the directory in which the currently executing script resides (see this). So if you typed __dirname
into /d1/d2/myscript.js
, the value would be /d1/d2
.
By contrast, .
gives you the directory from which you ran the node
command in your terminal window (i.e. your working directory) when you use libraries like path
and fs
. Technically, it starts out as your working directory but can be changed using process.chdir()
.
The exception is when you use .
with require()
. The path inside require
is always relative to the file containing the call to require
.
Let's say your directory structure is
/dir1
/dir2
pathtest.js
and pathtest.js
contains
var path = require("path");
console.log(". = %s", path.resolve("."));
console.log("__dirname = %s", path.resolve(__dirname));
and you do
cd /dir1/dir2
node pathtest.js
you get
. = /dir1/dir2
__dirname = /dir1/dir2
Your working directory is /dir1/dir2
so that's what .
resolves to. Since pathtest.js
is located in /dir1/dir2
that's what __dirname
resolves to as well.
However, if you run the script from /dir1
cd /dir1
node dir2/pathtest.js
you get
. = /dir1
__dirname = /dir1/dir2
In that case, your working directory was /dir1
so that's what .
resolved to, but __dirname
still resolves to /dir1/dir2
.
.
inside require
...If inside dir2/pathtest.js
you have a require
call into include a file inside dir1
you would always do
require('../thefile')
because the path inside require
is always relative to the file in which you are calling it. It has nothing to do with your working directory.
You can use the PUT method and pass data that will be included in the body of the request:
let data = {"key":"value"}
$.ajax({
type: 'PUT',
url: 'http://example.com/api',
contentType: 'application/json',
data: JSON.stringify(data), // access in body
}).done(function () {
console.log('SUCCESS');
}).fail(function (msg) {
console.log('FAIL');
}).always(function (msg) {
console.log('ALWAYS');
});
I've noticed that if you set the theme in the AndroidManifest, it seems to get rid of that short time where you can see the action bar. So, try adding this to your manifest:
<android:theme="@android:style/Theme.NoTitleBar">
Just add it to your application
tag to apply it app-wide.

This is not a direct answer to OP's question, this is more of the stuffs (experiments) I tried so far to solve the same problem and obtained some results and have some observations that I want to share, I am curious if we can have some further insights from this.
I just tried my minimax implementation with alpha-beta pruning with search-tree depth cutoff at 3 and 5. I was trying to solve the same problem for a 4x4 grid as a project assignment for the edX course ColumbiaX: CSMM.101x Artificial Intelligence (AI).
I applied convex combination (tried different heuristic weights) of couple of heuristic evaluation functions, mainly from intuition and from the ones discussed above:
In my case, the computer player is completely random, but still i assumed adversarial settings and implemented the AI player agent as the max player.
I have 4x4 grid for playing the game.
If I assign too much weights to the first heuristic function or the second heuristic function, both the cases the scores the AI player gets are low. I played with many possible weight assignments to the heuristic functions and take a convex combination, but very rarely the AI player is able to score 2048. Most of the times it either stops at 1024 or 512.
I also tried the corner heuristic, but for some reason it makes the results worse, any intuition why?
Also, I tried to increase the search depth cut-off from 3 to 5 (I can't increase it more since searching that space exceeds allowed time even with pruning) and added one more heuristic that looks at the values of adjacent tiles and gives more points if they are merge-able, but still I am not able to get 2048.
I think it will be better to use Expectimax instead of minimax, but still I want to solve this problem with minimax only and obtain high scores such as 2048 or 4096. I am not sure whether I am missing anything.
Below animation shows the last few steps of the game played by the AI agent with the computer player:
Any insights will be really very helpful, thanks in advance. (This is the link of my blog post for the article: https://sandipanweb.wordpress.com/2017/03/06/using-minimax-with-alpha-beta-pruning-and-heuristic-evaluation-to-solve-2048-game-with-computer/ and the youtube video: https://www.youtube.com/watch?v=VnVFilfZ0r4)
The following animation shows the last few steps of the game played where the AI player agent could get 2048 scores, this time adding the absolute value heuristic too:
The following figures show the game tree explored by the player AI agent assuming the computer as adversary for just a single step:
Hash #

Basically, when the column name starts with #

The DATEDIFF function is use to calculate the number of days between the required date
Example if you are diff current date from given date in string format
SELECT * , DATEDIFF(CURDATE(),STR_TO_DATE('01/11/2017', '%m/%d/%Y')) AS days FROM consignments WHERE code = '1610000154'
Here, STR_TO_DATE () : Take a string and returns a date specified by a format mask;
For your example :
SELECT dtCreated
, bActive
, dtLastPaymentAttempt
, dtLastUpdated
, dtLastVisit
, DATEDIFF(dtLastUpdated, dtCreated) as Difference
FROM Customers
WHERE (bActive = 'true')
AND (dtLastUpdated > '2012-01-01 00:00:00')

Browse to C:\windows\System32
and right click on cmd.exe
and run as Administrator. Worked for me on Windows 7.
If you are trying to run a script with elevated privileges you could do the same for the script file or use the scheduler's run as a different user option to run the script.
Try this
<script>
$().ready(function(){
$('.coupon_question').live('click',function()
{
if ($('.coupon_question').is(':checked')) {
$(".answer").show();
} else {
$(".answer").hide();
}

I create a file dif.go
that contains your code:
package dif
import (
"time"
)
var StartTime = time.Now()
Outside the folder I create my main.go
, it is ok!
package main
import (
dif "./dif"
"fmt"
)
func main() {
fmt.Println(dif.StartTime)
}
Outputs:
2016-01-27 21:56:47.729019925 +0800 CST
Files directory structure:

It works!
After you have done npm install material-design-icons
, add this in your main CSS file:

url(~material-design-icons/iconfont/MaterialIcons-Regular.woff) format('woff'),
url(~material-design-icons/iconfont/MaterialIcons-Regular.ttf) format('truetype');
}
.material-icons {
font-family: 'Material Icons';
font-weight: normal;
font-style: normal;
font-size: 24px; /* Preferred icon size */
display: inline-block;
line-height: 1;
text-transform: none;
letter-spacing: normal;
word-wrap: normal;

font-feature-settings: 'liga';
}
To add bold, italic and underline, just add the following to the font argument:
font=("Arial", 8, 'normal', 'bold', 'italic', 'underline')
Here's the nearly shortest possible solution to your question. The solution works in python 3.x. For python 2.x change the import
to Tkinter
rather than tkinter
(the difference being the capitalization):
import tkinter as tk
#import Tkinter as tk # for python 2
def create_window():
window = tk.Toplevel(root)
root = tk.Tk()
b = tk.Button(root, text="Create new window", command=create_window)
b.pack()
root.mainloop()
This is definitely not what I recommend as an example of good coding style, but it illustrates the basic concepts: a button with a command, and a function that creates a window.
You don't need AJAX for this, just some plain java script setting the background-color property of the body element, like this:
document.body.style.backgroundColor = "#AA0000";
If you want to do it as if it was initiated by the server, you would have to poll the server and then change the color accordingly.

The interpretation of the backspace and carriage return characters is left to the software you use for display. A terminal emulator, when displaying \b would move the cursor one step back, and when displaying \r to the beginning of the line. If you print these characters somewhere else, like a text file, the software may choose. to do something else.

In PL/SQL v.10
keyword declare is used to declare variable
DECLARE stupidvar varchar(20);
to assign a value you can set it when you declare
DECLARE stupidvar varchar(20) := '12345678';
or to select something into that variable you use INTO
statement, however you need to wrap statement in BEGIN
and END
, also you need to make sure that only single value is returned, and don't forget semicolons.
so the full statement would come out following:
DECLARE stupidvar varchar(20);
BEGIN
SELECT stupid into stupidvar FROM stupiddata CC
WHERE stupidid = 2;
END;
Your variable is only usable within BEGIN
and END
so if you want to use more than one you will have to do multiple BEGIN END
wrappings
DECLARE stupidvar varchar(20);
BEGIN
SELECT stupid into stupidvar FROM stupiddata CC
WHERE stupidid = 2;
DECLARE evenmorestupidvar varchar(20);
BEGIN
SELECT evenmorestupid into evenmorestupidvar FROM evenmorestupiddata CCC
WHERE evenmorestupidid = 42;
INSERT INTO newstupiddata (newstupidcolumn, newevenmorestupidstupidcolumn)
SELECT stupidvar, evenmorestupidvar
FROM dual
